High-Throughput Complex Disease Modeling for Ethical Drug Discovery: Clinical Relevance of a NAM Platform for Cancer Biomarker Development

May 2026 DOI 10.14302/issn.2572-3030.jcgb-26-6307

The development of tumor biomarkers derived from blood, or its components, has become pivotal in advancing early cancer diagnosis. Malignant transformations induce cancer-specific alterations in the transcriptome, proteome, and secretome of tumor cells. Recent studies highlighted similar alterations in peripheral blood mononuclear cells (PBMCs) in cancer patients, which appear to mirror the state of transformation in tumor cells. These findings suggest an intercellular communication–driven mechanism rather than a systemic inflammatory response and, in addition to current ctDNA-based liquid biopsy biomarkers, point to a novel, simple, and highly robust approach for the early detection of cancer. Using this phenomenon to advance PBMC-based biomarker development, it will be essential to achieve 3D in vitro tumor models that reproduce a highly physiological tumor microenvironment (TME). Likewise, more enhanced 3D ex vivo models are required to enable the replication of cell-to-cell and organ-to-organ communication. These systems will guide the self-organization of mixed microenvironments derived from different tissues and enable them to accurately reproduce the molecular connections underlying these alterations. In this study, an innovative new modular 3D co-culturing approach was used to expose PBMCs to lung tumoroids, under physiologically relevant conditions. Changes in DNA fragmentation of PBMCs in the presence of lung cancer were quantified and used as a biomarker. To validate the predictiveness of this biomarker, our results were compared with clinical data from a clinical evaluation study. Similar to the clinical trial observations, PBMCs, when exposed to lung tumoroids, showed a significantly lower level of DNA fragmentation (37%). This modular 3D co-culturing model showed a predictiveness of the clinical data of > 90%, demonstrating its power to monitoring cell-to-cell communication effects and support the development of blood-based biomarkers.

Apomorphine Subcutaneous Infusion is More Efficient Than foslevodopa/foscarbidopa Subcutaneous Infusion in the Treatment of Advanced Parkison´s Disease for the Spanish National Health System

May 2026 DOI 10.14302/issn.2641-4538.jphi-26-6161

Objectives Motor fluctuations and non-motor disorders not manageable by first-line treatments in advanced Parkinson's disease require continuous dopaminergic stimulation strategies such as subcutaneous infusions of apomorphine (APO) or foslevodopa/foscarbidopa (FLD/FCD). A Budget Impact Analysis (BIA) was performed to estimate the cost difference between both treatments assuming equivalent clinical efficacy and safety. Material and methods The efficacy results of pivotal clinical trials at 12 and 52 weeks of treatment and the safety profile of APO vs FLD/FCD were compared, based on latest scientific publications and other available clinical data. A comparative BIA was performed, based on estimated annual drug treatment costs at Spanish published prices. Results The efficacy of APO (16 h/day) and FLD/FCD (24 h/day) in reduction of OFF hours (2.47 vs 2.75, 12 weeks; 3.66 vs 3.50, 52 weeks; respectively) and increase of ON hours without disabling dyskinesias (2.77 vs 2.72, 12 weeks; 3.31 vs 3.80, 52 weeks; respectively) could be considered clinically equivalent, as well as their safety profiles. However, a significant discrepancy is observed in the costs of the aforementioned alternatives. Considering published prices and the average dose reported in the literature, in Spain the annual cost of APO would be €13,980 compared to €55,198 for FLD/FCD. Consequently, the financial resources required for the treatment of FLD/FCD would enable the treatment of approximately three to four patients with APO. The BIA indicated the potential for annual savings in more than €2,500 million, considering a total target population of over 60,000 patients per year. Finally, an univariant sensitivity analysis was performed, considering a scenario in which the hospital acquisition cost of FLD/FCD decreased between 20%-30% (€44,159- €38,638/year). In this scenario, the total annual savings range between €1,875-€1,532 million per year. Conclusions Overall APO is more efficient than FLD/FCD, as it provides similar clinical efficacy at a lower treatment cost. The selection of an appropriate treatment option is to be determined by clinical criteria and patient characteristics, but cost evaluation should be considered to select the most cost-effective therapeutic option.

Toward Better Care for Sickle Cell Disease in Nigeria: A Review of Challenges and Interventions

Dec 2025 DOI 10.14302/issn.2997-1977.jd-25-5754

With more than 150,000 affected infants annually, Nigeria bears the largest burden worldwide of sickle cell disease (SCD), making it a significant public health concern. The management of SCD in Nigeria is challenging, despite advancements in medical research and increased knowledge. This review examines the numerous issues surrounding SCD in the nation, including the financial burden on affected families, the lack of specialized care facilities, the absence of newborn screening programs, the sociocultural stigmatization of SCD, and restricted access to high-quality healthcare. Additionally, inadequate public health education and a lack of coordinated national policies result in delayed diagnosis and suboptimal treatment outcomes. We also highlighted recent efforts and recommendations aimed at improving early detection, comprehensive care, and community support. Addressing these challenges through expanded health education and enhanced healthcare infrastructure is essential to reducing morbidity and mortality associated with SCD in Nigeria.

Comparative Study of Deep Learning Techniques for Detecting Corn Plant Leaf Diseases Using Transfer Learning

Mar 2025 DOI 10.14302/issn.2638-4469.japb-25-5395

Plant leaf diseases pose significant threats to crop yield and agricultural sustainability, making early and accurate detection crucial for effective disease management. In current years, deep neural network (DNN) techniques have shown remarkable potential in the field of image classification, including plant disease detection. The study aims to investigate the performance of two popular deep learning architectures, namely, VGG16 and InceptionResNetV2, for the detection of tomato plant leaf disease. The proposed methodology involves acquiring a diverse dataset comprising high-resolution images of healthy and diseased leaves from the target crops. Preprocessing techniques such as image augmentation and normalization are applied to enhance the generalization ability of the models and mitigate overfitting. Transfer learning is employed to initialize the deep learning architectures with weights pre-trained on large-scale image datasets to accelerate convergence and improve the models' performance in limited data scenarios. To evaluate performance of proposed networks various metrics such as validation and test accuracies, precision and recall, F1 score, and the area under the curve (AUC) are considered. From the investigations, the classification accuracy of the finest architectures is as follows: 99.8 percent for VGG16 and 99.4 percent for InceptionResNetV2 on Corn Leaves. The results suggest that the models developed during the investigation phase to identify the leaf disease were superior to any existing Deep Neural Networks (DNNs).

Why Do Human Body Systems Go Into Catastrophic System Failure Leading to Diseases -Is the Answer in Science or Nature?

Oct 2024

Both the human body and the natural world are governed by multiple complex systems. These systems have feedback loops which is a process in which the outputs of a system are circled back and used as inputs. Where there are multiple systems, there is always the potential for a catastrophic system failure. If a system fails in the human body, this can lead to a number of life-threatening and debilitating diseases such as cancer. Diseases such as cancer is in effect, the result of a catastrophic system failure. There are cancer cases in which the root cause of the disease is unknown. System failure in the human reproductive system can lead to congenital birth defects. In cases of a system failure leading to congenital birth defects, some of the causal factors are known but in 65% of these cases, the reasons for this reproductive system failure are unexplained. There are neurological diseases such as Parkinson’s, multiple sclerosis and Alzheimer’s where again, the root causes are unknown. Then there are a number of infectious diseases where the root cause is unknown. The initial causative factors for most of these human diseases are well known. What has yet to be fully understood is the primary root cause that triggers and underpins these system failures in the first place. Nature also has devastating system failures such as in earthquakes and hurricanes. Humans and nature are a close partnership and nature can influence human health. Nature’s systems are deeply interconnected and often exhibit complex behaviours due to positive and negative feedback loops present in both nature and human body systems. Using systems methodology and systems thinking and philosophical insights, the objective is to try to ascertain the answer as to why there are these unknown root causes of diseases; questions that presently, science alone cannot explain. It will be argued that as man and nature are as one, the answers as to why human body systems fail leading to disease may lie not in science but in nature.

Primary Healthcare Services and Health-Related Quality of Life of Older Persons with Non-Communicable Diseases: A Narrative Literature Review

Sep 2024 DOI 10.14302/issn.2693-1176.ijgh-24-5233

In response to the rising burden of non-communicable disease (NDC), the World Health Organization (WHO) developed tools to enable early detection and management of NCDs in Primary Healthcare centers (PHC). Globally, the prevalence of NCDs remains alarmingly high with 41 million deaths annually. Of these, 17 million people die before the age of 70, and 86% of these premature deaths occur in low-and middle-income countries. This narrative review aimed to assess the effect of PHC services on health-related quality of life (HRQoL) of older persons with NCDs, to critically analyze the potential of the existing literature in informing improvements in PHC services. We searched various databases (PubMed, Springer, Scopus, and ScienceDirect) for relevant literature. Peer-reviewed articles on the influence of PHC services on HRQoL among older persons with NCDs written and published in English between January 2013 and May 2024 were considered. The review indicates that effective PHC services are linked to good HRQoL. However, PHC services are sub-optimal and poor in low- and middle-income countries, hence more health interventions are essential to improve PHC services to enhance HRQoL of older persons.

Health-Related Quality of Life Perception Among Older Persons with Non-Communicable Diseases in Primary Healthcare Facilities: A Qualitative Inquiry

Sep 2024 DOI 10.14302/issn.2693-1176.ijgh-24-5215

Background The understanding of older persons with non-communicable diseases (NCDs) regarding health well-being is paramount and can translate to increased self-efficiency, independence, and enhanced well-being. However, little is known about older persons' understanding of the concept of health-related quality of life (HRQoL) in Uganda. The study explored perceptions and unveiled understanding of older persons with NCDs on HRQoL in central Uganda. Methods This exploratory qualitative study design involved 23 participants recruited from selected Primary healthcare facilities in Central Uganda. Thematic analysis using an inductive approach generated themes that informed the study's qualitative findings. Results The study highlighted the physical domain as a key component of HRQoL, encompassing holistic well-being, lifestyle modification, and financial stability. To promote well-being and support a healthy aging journey, it is essential to adopt a person-centered approach that aligns with the perceptions of older adults on HRQoL.

A Systematic Review of Dengue Fever and Dengue-Associated Neurological Conditions Was Conducted in an Attempt to Better Understand This Disease

Jun 2024 DOI 10.14302/issn.2374-9431.jbd-24-5077

Dengue is a global arbovirus disease primarily carried by Aedes aegypti and Aedes albopictus mosquitoes. It has four serotypes (DENV1, DENV2, DENV3, and DENV4) and is classified into distinct genotypes. The epidemic is complicated by immunological interactions and viral lineage turnover. Neurological problems are commonly associated with DENV2 and DENV3, with DENV2 displaying the most severe symptoms. Direct viral invasion, host-mediated immune system reactions, or host-mediated metabolic alterations can all result in dengue-related neurological issues. The three dengue vaccinations and the significance of meta-analyses for genetic data will also be covered. Finally, establish a connection with the microRNAs associated with dengue fever, creating new opportunities for the creation of dengue treatment regimens involving microRNAs.

Development of Municipal Decision-Making Strategies as Management Tools to Combat Waterborne Diseases

May 2024

Waterborne diseases pose a significant global public health threat, particularly in sub-Saharan Africa, where frequent outbreaks occur. These diseases stemming from contaminated drinking water, poor waste management, and insufficient hygiene contribute to high morbidity and mortality in children under 5 years old. A study addressed waterborne diseases in N'Djamena, Chad's 3rd and 9th districts, through decision-making strategies. The research employed various methods, including a household survey using questionnaires, workshops, semi-structured interviews, and focus group discussions. Additionally, documentary research provided essential data for analysing the situation of diseases in the community. Epidemiological data from 2019- 2022 indicated a substantial prevalence of diseases such as diarrhoea, dysentery, skin infections, typhoid, abdominal pain, and malaria, with notable mortality, especially among children. Among surveyed households, 50% believed the consumed water was contaminated, attributing it to faecal matter, while 28% and 22% linked the diseases to inadequate hygiene and unsanitary conditions, respectively. The study advocates for comprehensive strategies, including improving water treatment efficiency, implementing safe waste management, promoting hygiene, and vaccination. Active involvement of all stakeholders, with municipal authorities leading, is crucial for effective implementation and combating waterborne diseases.

Is Vagus Nerve Therapy a Potential Alzheimer's Disease Treatment?

Dec 2023 DOI 10.14302/issn.2693-1176.ijgh-23-4854

A potential treatment for Alzheimer's disease is vagus nerve therapy, which has been made possible by considerable advances in neuroscience. An essential component of the autonomic nervous system, the vagus nerve regulates memory, inflammation, and cognition. Researchers hope to delay the progression of Alzheimer's disease and improve cognitive function by implanting a vagus nerve stimulator (VNS). Alzheimer's patients have higher heart rate variability, according to an ECG study, which may be advantageous. To completely grasp its mechanics and long-term effectiveness, more research is necessary.

Rheumatic Heart Disease In Chad: Clinical, Paraclinical, Therapeutic And Progressive Aspects

Dec 2023 DOI 10.14302/issn.2329-9487.jhc-23-4848

Introduction Rheumatic heart disease is mostly common in low-income or developing parts of the world, such as Sub-Saharan Africa, with a high morbidity and mortality rate. There are few data that are available in Chad on rheumatic heart disease. Our objective was to study the clinical, echocardiographic, therapeutic, and progressive aspects of rheumatic heart disease at the Renaissance University Hospital Center and the National Reference Teaching Hospital in N’Djamena, Chad. Patient and methods This was a prospective, multicenter and observational cohort study, covering a consecutive series of patients consulted and/or hospitalized for rheumatic heart disease, documented by an echocardiogram from January 2015 to January 2021. Results Among the 4456 patients consulted and/or hospitalized, 398 cases of rheumatic heart disease (8.9%) were collected, and 364 patients had met the inclusion criteria. The mean age was 31.2 ± 14.4 years, and 193 patients (53%) were female. On admission, heart failure was present in 214 patients (58.8%), ischemic stroke in 10 patients (2.7%) and supraventricular arrhythmias such as atrial fibrillation in 94 patients (25.8%) and atrial flutter in 6 patients (1.6%). Mitral regurgitation was observed in 49.7% (n=181) of cases, aortic regurgitation in 33.2% (n=121), mitral stenosis in 31.3% (n=114), and aortic stenosis in 7.7% (n=28). At least two valvular disorders were combined in 48.4% of cases. A surgical intervention such as a heart valve replacement and/or valvuloplasty was performed in 80 patients (22.2%). At least one rehospitalization was noted in 56.9% of patients. Forty-two of the 150 patients free of heart failure at inclusion (28%) had experienced the first episode of decompensated heart failure during follow-up. On the other hand, in 119 patients (55.6%), it was the second episode of decompensated heart failure. Other progressive complications included atrial fibrillation (13.8%), thromboembolic complications (6.3%), infective endocarditis (6.0%) and prosthetic valve dysfunction (1.4%). Altogether, the mortality rate was 10.4%. It was 9.9% in non-operated patients compared to 12.5% in operated patients (p=0.49). Conclusion The present study shows that morbidity and mortality of rheumatic heart disease remain high in our context and often affect children, young adults, and women. Treatment is essentially based on cardiac surgery which is not available in Chad.

A 5 years old female child recovered from Moyamoya Disease with Unani formulation: A Case Report

Mar 2023

Moyamoya disease is a very rare chronic circulatory occlusive disorder of the blood vessels of the brain, in which patients complain of headache, seizure, weakness, and sometimes paralysis. A 5 years old female child with a complaint of headache and seizure was admitted elsewhere and during the treatment, she was diagnosed with Moyamoya disease. Further, she went to AIIMS Patna, where the neurosurgeon advised Digital Subtraction Angiography (DSA) and after the final diagnosis, they suggest the surgical intervention of the brain. During the search for an alternative treatment, they consulted my center for Unani treatment. We advised a semiliquid Unani polyherbal formulation containing Gule Banafsha (Viola odorata), Ustukhuddoos(Lavandula stoechas), and Nilofer (Nymphaea alba Linn) for three months. After the completion of the treatment schedule, she went for DSA again in Patna AIIMS and they find that there is no sign of occlusion in the blood vessels of the brain. The patient has no complaints and the report also showed that she gets improved. 

Outcome of Percutaneous Coronary Intervention Among Very Elderly Patients with Ischemic Heart Disease

Sep 2022

Background Cardiovascular disease, and ischemic heart disease (IHD), is a major cause of morbidity and mortality in the very elderly patients worldwide. In the developing countries like Bangladesh it has been increasing with time. Due to life style, food habits and urbanisation. These patients represent a rapidly growing cohort presenting for percutaneous coronary intervention (PCI), now constituting more than one in five patients treated with PCI in real-world practice. Materials and Methods From July 2020 we included 152 patients with IHD purposively in Cardiology department of Bangabandhu Sheikh Mujib Medical University Dhaka, Bangladesh undergone PCI who were divided into 2 groups according to age: e” 75 years (n = 51) and <75 years (n = 101). Baseline clinical characteristics, indications for coronary intervention, in hospital outcomes were obtained. Study endpoint was Renal impairment, MI, LVF, emergency revascularization and death. Results Very elderly patients were more frequently male (86.2%) and nonsmoker at present (41.1% vs. 63.3%, p=0.003), had higher prevalence of hypertension (60.7% vs. 50.4%, p<0.13), and more often presented with NSTEMI (54.9% vs. 23.7%, p<0.001). Elderly group had higher incidence of TVD and LM disease (37.2% vs. 26.7% and 9.8% vs. 2.9%, p=0.07) and more incidence of ostial (17.6% vs.5.9%,p=0.007) and calcified lesions (31.3% vs. 14.8%, p=0.004). Procedural success (TIMI III) were high in both groups, but still lower in the elderly as compared to younger group (96% vs. 97%, p=0.65). Very elderly patients had higher incidence of post PCI bleeding, CIN, MI, LVF and death (9.8% vs.5.9%, 7.8% vs.3.9%, 5.8% vs.5.9%, 9.8% vs. 4.9% and 5.8%vs.3.9%,p=0.07), whereas emergency revascularization were higher in younger group (5.8% vs. 6.9%, p=0.07). Conclusion Very elderly patients aged ≥80 years face more vascular site complications during PCI, usually have more LM and TVD with more ostial and calcified lesions in comparison with younger group. Though procedural success is similar with younger group, they face more post PCI CIN, LVF and MI. Repeat revascularization was higher in younger group.

A Clinical, Electrocardiographic and Echocardiographic Comparison of Patients with Single Vs Multivessel Disease Presenting with Acute Coronary Syndromes

Sep 2022 DOI 10.14302/issn.2329-9487.jhc-22-4252

Background Prevalence of coronary artery disease is between 7-13 percent in urban and 2-7 % in rural India1. The alarm in rise in the prevalence of coronary risk factors like diabetes, hypertension, dyslipidemia, smoking, central obesity and physical inactivity2. The correlation between these risk factors and the severity of coronary atherosclerosis, assessed by angiography which may be either single or multivessel is less consistent with studies reporting conflicting results 3,4. Therefore our study aims to understand the proper correlation between risk factors and severity of coronary artery disease in an Indian population Methods This study was conducted in the department of cardiology, NIMS hospital Hyderabad which receives patients from the urban as well as rural areas of Telangana. the patients admitted in the department of cardiology, NIMS hospital Hyderabad that presented with acute coronary syndromes and diagnosed to have coronary artery disease (single vessel/multivessel disease) on coronary angiography taken for study. Sample Size is 150 Results Among the 150 subjects, males were 111(74%) and females were 39(26%). Mean age of the study population is 55.2 ± 11.4. Among SVD group 73.65% were males &26.3% were females. Among MVD group 76.2% were males & 23.7% were females. Mean age for SVD was 53±14.4 years, while mean age foe MVD was 58.6±14.5 years. For ACS mean age of presentation for females is 60.7±11.4 and for males mean age of presentation is 55.1±12.6. MVD (57.2%) were more common among smokers than SVD. In <45 years age group SVD (69.2%) were more common than MVD (30.8%). In 45- 70 years age group and >70 years age group MVD were more common than SVD with 69.6% and 66.6% respectively, which is statistically significant. MVD (60%) were more common among hypertensives than SVD. Among non-hypertensives MVD (41.8%) was less common than SVD (58.2%) MVD was common among all age groups, which is statistically signicant. Among STEMI group SVD (58.3%) was more common than MVD (41.7%). Among NSTEMI group MVD (62%) was more common than SVD (38%).Correlation between groups was statistically significant. Among SVD study group, LVEF was commonly between 30-45% & very few with LVEF <30% MVD was associated with more severe LV dysfunction as compared to SVD in acute MI. The difference in ejection fraction between the two groups was statistically significant P value=0.0002. In hospital MACE Among SVD there was 1 MI (due to stent thrombosis) who had to TVR (primary PCI) & rest were asymptomatic and discharged in normal state MVD there were in hospital deaths (due to refractory cardiogenic shock) rest were asymptomatic and were discharged in normal state. This difference between the two groups was statistically insignificant. Conclusion Multivessel disease in ACS were seen more commonly among elderly as compared to young subjects where single vessel disease were more common. Females especially elderly more commonly have multivessel disease. Mean age for multivessel disease was higher than single vessel disease. Among <45 years age group, SVD was more prevalent among smokers, obese and physically active. Multi vessel disease is more prevalent among patients with risk factors like diabetes, hypertension, dyslipidemia and physically inactive. Subjects with family history of premature CAD presented early and correlated well with prevalence of SVD.NSTEMI presented more with multi vessel disease. In echocardiographic wall motion analysis, a depressed regional segment of infarcted area with remote hyperkinesis predicted SVD where as remote area hypokinesis predicts more multivessel disease. In hospital outcomes were seen among multi vessel disease as compared to single vessel disease although not statistically significant.

Tay-Sachs Disease: From Molecular Characterization to Ethical Quandaries and the Possibility of Genetic Medicine

Jun 2022 DOI 10.14302/issn.2470-5020.jnrt-22-4217

Tay-Sachs disease (TSD) is a rare neurodegenerative disorder caused by mutations in the HEXA gene, which encodes the ɑ subunit of the enzyme β-hexosaminidase A. Lacking this key enzyme in GM2 ganglioside catabolism, individuals who are homozygous for HEXA mutations suffer from abnormal accumulation of GM2 ganglioside in brain and nerve cells, ultimately resulting in the progressive deterioration of the central nervous system. TSD is one of three disorders characterized by β-hexosaminidase deficiency; Sandhoff disease (SD) and the AB variant arise by mutations in the HEXB and GM2A genes respectively, which disrupt other points of GM2 ganglioside degradation. Characterized by developmental delay and stagnation, muscular weakness, coordination deficits, seizures, and eventual hearing and vision loss, these three disorders are clinically indistinguishable and occur in three forms defined by age of onset. While there is a much higher incidence of TSD in the Ashkenazi Jewish population, community carrier screening and counseling initiatives have reduced disease prevalence to about the equivalent of non-Jewish populations; however, such efforts have raised ethical concerns in the Jewish community that are increasingly relevant in light of scientific and medical advancements. Currently, treatments for TSD and its related disorders focus on symptom management, with gene therapies and the application of modified CRISPR-Cas-9 technology being explored.

Integrated Management of Sclerotinia Sclerotiorum, An Emerging Fungal Pathogen Causing White Mold Disease

Jun 2022 DOI 10.14302/issn.2832-5311.jpcd-22-4182

Sclerotiniasclerotiorum, the causal agent for white mold (Sclerotinia stem rot), is a devastating fungal pathogen. Currently, Sclerotinia is most commonly managed using the chemical fungicide which can lead to Sclerotinia resistance development, impacting biodiversity and interfering with key ecosystem services. In this regards, field experiments were conducted during 2017-18 planting seasons to evaluate the efficacy of different components viz. sawdust burning, stable bleaching powder, fungal and bacterial bio-control agents, chemical fungicide Rovral 50 WP and integration of different components for the management white mold disease of bush bean, mustard and garden pea in three different locations viz. in the field of Plant Pathology Division, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur, Regional Agricultural Research Station (RARS), Burirhat, Rangpur and RARS, Ishurdi, Pabna, respectively. The results showed that different treatments displayed varying levels of effectiveness against the disease. All the treatments gave satisfactory reduction of white mold disease development and increased plant growth as well as yield of bush bean, mustard and garden pea. Among the treatments, integration of saw dust burning + soil amendments with Trichoderma based bio-fungicide + bacillus based bio-control agents + application fungicide Rovral 50 WP is the best treatment which reduced 97.49%, 77.72%, 72.26% white mold disease incidence and 84.61%, 81.14%, 71.01% white mold disease severity of mustard, bush bean and garden pea, respectively and increasing plant growth parameter as well as 52.16%, 27.74%, 36.97% yield of mustard, bush bean and garden pea, respectively. Application of only fungicide Rovral 50 WP also better treatment in reduction of white mold disease incidence and disease severity and increasing plant growth parameter as well as increasing yield of mustard, bush bean and garden pea. Soil amendment with fungal or bacterial bio-control agents also gave satisfactory results in reduction of white mold disease incidence and disease severity and increasing plant growth parameter as well as increasing yield of mustard, bush bean and garden pea. It could be concluded from the obtained results that integration between bio-control agents as a soil treatment and foliar application chemical fungicide might be useful as a good tool for controlling white mold disease caused by S.sclerotiorum and obtained higher yield of bush bean, mustard and garden pea under field condition.

Microalbuminuria and the Presence of Hypoxemia in Patients with Chronic Obstructive Pulmonary Disease

Jun 2022 DOI 10.14302/issn.2642-9241.jrd-22-4181

Introduction Worldwide, the Chronic Obstructive Pulmonary Disease (COPD) is a major public health concern; On the basis of epidemiologic data, by 2020, COPD will be the third leading cause of death worldwide. Objective To assess the frequency of Microalbuminuria and the presence of Hypoxemia in patients with COPD. Materials and Methods Study Design Cross-sectional observational study. Place of Study Department of Medicine & Respiratory Medicine in Dhaka Medical College Hospital (DMCH). Study Period Six months after approval of the protocol Study Population Patient suffering from COPD and admitted in Department of Medicine & Respiratory medicine, DMCH, Dhaka, Bangladesh. Total 100 samples were included in this study. COPD usually presents with a history of chronic cough with sputum production or exertional breathlessness which may be associated with relevant clinical findings and a post-bronchodilator FEV1/FVC less than 0.7. In most cases it is associated with smoking Results Total 100 patients of COPD were included in the study. Mean age was 58.16±5.4 years ranging from 50 to 74 years. Out of 100 patients, majority (42%) were from age group 55 to 60 years. Among all, 82% patients were male and 18% were female, of 100 patients, majority (30%) were day laborer. Only 2% were unemployed. The percentage of housewives was 18%. Other 34% were businessman and service holders. COPD severity was assessed using GOLD guideline. Out of 100 COPD patients, 38% had severe COPD (GOLD stage III). 16 % patients were in mild (Stage I) and 32% patients were in moderate stage (Stage II). The condition was very severe for 14% patients (Stage IV). Of 100 COPD patients, 30% had microalbuminuria. Among 100 COPD patients, chance of microalbuminuria increases among COPD patients with the increase of age significantly. There is smoking history of 36 pack year for COPD patients with microalbuminuria. Of 100 patients 26% were hypoxemic. The average forced expiratory volume (FEV1%) was 37.40 with standard deviation 14.48 for patients with microalbuminuria. The PaO2 and PaCO2 is 63.06 with standard deviation 7.09 and 46.09 with standard deviation 2.43 for COPD patients with microalbuminuria respectively. All of these characteristics are significant with p-value 0.00. However, the body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were not found significant. The patients who had PaO2 less than 70 mmHg were considered hypoxemic. The patients who had microalbuminuria among them 87% were hypoxemic. Only 13% patients were free from hypoxemia who had microalbuminuria. Patients without microalbuminuria had no history of hypoxemia. There is significant relation exists between hypoxemia and the presence of microalbuminuria (p<0.5). Conclusion In this study, about one-fourth of the patients have hypoxemia and more than one fourth of the patients have microalbuminuria. Stage III was more frequent among the study population but there was no association between severity grading and presence of microalbuminuria. However, significant relation is found between co-existence of both microalbuminuria and hypoxemia in COPD patients.

Knowledge, Attitudes and Practices about Cardiovascular Diseases among Adult Patients Attending Public Health Centers in Kigali city, Rwanda

May 2022 DOI 10.14302/issn.2641-4538.jphi-22-4189

In Rwanda, CVDs accounts around 14% of all death. Studies on knowledge, attitude, and practice (KAP) would be of great value in helping public health professionals develop targeted programs and measure the effectiveness of interventional programs. The main objective of this study was to analyze the KAP about CVDs among adult patients attending public health centers located in the City of Kigali, Rwanda. A total of 384 adult patients were enrolled in this study. A structured questionnaire was used. Data entry and analysis was done using SPSS version 21. Findings were presented as frequencies and percentages in tables. For determining the KAP-levels, the overall scores were determined for each respondent by adding up the scores through the KAP-related questions. The mean age was 36.4 years, primary school (57.3%), married (62.8%), self-employed (40.9%), and females predominated (61.5%). The knowledge mean score was 14.2 and 76% had high level of knowledge of CVD risks and prevention. The average attitude score for all respondents was 17.6 and 22.9% of the respondents showed negative attitude towards CVDs prevention. Research findings revealed that 36.5 % were not practicing physical activity and exercise. The mean practice score for all respondents was 3.9 and 70% of respondents had negative practice towards CVDs prevention. Poor CVDs prevention practices were observed among the study participants. Therefore, it is necessary to establish more effective educational interventions intended to promote positive health behaviors related CVD prevention

A Cancer Theory: The Central Nervous System’s Adaptive Changes Make Chronic Diseases Incurable

Mar 2022 DOI 10.14302/issn.2471-7061.jcrc-22-4139

We examined special roles of the Central Nervous System (CNS) in an attempt to resolve the puzzle that chronic diseases cannot be cured in medicine. By exploring a skill-learning model, we found that the CNS is able to remember certain information reflecting biochemical and cellular (B&C) processes in the body. From the skill-using ability, we found that the CNS is able to control basic B&C processes that drive and power the skill. From the ability to adjust forces and moving direction of body parts, we infer that the CNS is able to adjust B&C processes that control physical acts. From this controlling capability, we inferred that the CNS must also store certain information on the baseline B&C processes, is able to up-regulate or down-regulate the B&C processes, and make comparisons in performing its regulatory functions. We found that chronic diseases are the results of deviated baseline B&C processes, the CNS plays a role in maintaining deviated baseline B&C processes, and protects the body state of a fully developed disease. The three CNS roles can explain that cancer progresses with increasing malignancy, cancer quickly returns after a surgery, cancer cells repopulate after chemotherapy and radiotherapy, cancer patients develop drug resistance inevitably, immune cells rebound after suppression, etc. We further showed that long-term exercises generally can correct part of the departures in B&C processes and thus help to reverse chronic diseases. Finally, we propose strategies for resetting the CNS’ state memory as an essential condition for curing chronic diseases and cancer.

Two-Phase Lung Damage Mechanisms For COVID-19 Disease, and Driving Force and Selectivity in Leukecyte Recruitment and Migration

Mar 2022 DOI 10.14302/issn.2642-9241.jrd-22-4132

To understand lung damages caused by COVID-19, we deduced two phases lung damage mechanisms. After the lungs are infected with COVID-19, the affected lung tissue swells and surface properties of pulmonary capillaries change, both contributing to an increased flow resistance of the capillaries. The initial damages are mainly fluid leakage in a limited number of involved alveoli. The increased vascular resistance results in retaining more white blood cells (“WBCs”) in pulmonary capillaries. Some of the WBCs may get into interstitial spaces. When more and more WBCs are dynamically retained, the vascular resistance of pulmonary capillaries further rises; and thus the overall vascular resistance of the lungs rises and pulmonary pressure rises. The rise in the pulmonary pressure in turn results in elevated capillary pressures. When pulmonary capillary pressures around the alveoli are sufficiently high, the elevated pressure causes interstitial pressures to change from normally negative values to positive values. The positive pressures cause fluid leakage to the alvoeli and thus degrade lung function. Tissue swelling, and occupation of WBCs in interstitial spaces and occupation of alvoelar spaces by leaked water result in reduced deformable and compressible spaces, and thus causes a further rise of the vascular resistance of the lungs. When the pulmonary pressure has reached a critical point as in the second phase, the blood breaks capillary walls and squeezes through interstitial spaces to reach alveolar spaces, resulting in irreversible lung damages. Among potential influencing factors, the available space in the thorax cage, temperature, and humid are expected to have great impacts. The free space in the thorax cage, lung usable capacity, and other organ usable capacities are the major factors that determine the arrival time of last- phase irreversible damage. The mechanisms imply that the top priority for protecting lungs is maintaining pulmonary micro-circulation and preserving organ functions in the entire disease course while controlling viral reproduction should be stressed in the earliest time possible. The mechanisms also explain how leukecytes are “recruited and migrated” into inflamed tissues by dynamic retention.

Feb 2022 DOI 10.14302/issn.2639-3166.jar-21-4019

This article has been retracted on 10 November 2022. VIEW THE RETRACTION NOTICE (https://doi.org/10.14302/issn.2639-3166.jar-25-5841) A field experiment was conducted with a view to test the efficacy of Tricho-composts and integration of Tricho-composts, poultry refuse (PR), neem oilcake (NOC), saw dust burning (SDB) with chemical nematicide Furadan 5G (Carbofuran) for controlling root knot nematode of country bean through which growers will be benefited. The root-knot nematode infested soils were treated with Tricho-compost-1 @ 2 kg/pit, Tricho-compost-2 @ 2 kg/pit, Tricho-compost-1 @ 2 kg/pit + Furadan 5 G @ 20 g/pit, Tricho-compost-2 @ 2 kg/pit + Furadan 5 G @ 20 g/pit, poultry refuse @ 5-6 kg/pit + Furadan 5 G @20 g/pit , neem oil cake @ 500 g/pit + Furadan 5 G @ 20 g/pit and saw dust burning + Furadan 5 G @ 20 g/pit. It was revealed that all the treatments performed well in reducing root-knot nematode infestation and increasing plant growth and yield country bean compared to farmers’ practices. Among the treatments, integration of poultry refuse with Furadan 5G or Trichoderma based bio-fungicides Tricho-composts with Furadan 5G or neem oil cake with Furadan 5G are the best treatments in reducing root-knot nematode infestation and increasing plant growth as well as yield of country bean. Soil treatment with only Tricho-composts or integration of saw dust burning with Furadan 5G also performed better in reduction of root knot nematode disease and increasing plant growth as well as yield of country bean.

Thyroid Function Abnormalities in Patients with Chronic Kidney Disease

Feb 2022 DOI 10.14302/issn.2574-4488.jna-21-4039

The function of the thyroid gland is one of the most important in the human body as it regulates the majority of the body's physiological actions. The thyroid produces hormones (T3 and T4) that have many actions including metabolism, development, protein synthesis, and the regulation of many other important hormones. There is a lot of interaction between the kidney and thyroid gland during the disease States thyroid hormones have a major role in regulating the glomerular filtration rate through its hormonal actions in normal physiology. But these things are altered in the disease States such as chronic kidney disease. It is a well-known fact that hypothyroidism causes decreased Glomerular filtration rate whereas hyperthyroidism causes increased Glomerular filtration rate leading to renin-angiotensin-aldosterone system activation. In our study we aim to see the prevalence of low T3 syndrome in different stages of CKD which is a state of physiological benefit in preserving the proteins lost through the Kidneys in CKD patients and since CKD is progressed in hyperthyroidism state it is a protective mechanism in restoring the CKD status. Other subclinical hypothyroidism hyperthyroidism. Autoimmune hypothyroidism. Glomerulonephritis are all part of a dynamic endocrine and nephrology sequence. Thorough knowledge of these is required for optimum treatment of thyroid in CKD patients.

COVID-19 epidemic, described as a community health emergency by the World Health Organization, began in December 2019. COVID-19 is a source of deep vein thrombosis (DVT) because of hypercoagulation, blood stasis, and endothelium injury complications. This study reports a 26-year-old pregnant woman with coronavirus hospitalized with a left ovarian vein (LOV) thrombosis at Sultangazi- Haseki Training and Research Hospital in Istanbul. Risk classification for DVT disease is of crucial importance for the forecast of coronavirus.

Features of the Emergence and Re-Emergence of Infectious Diseases, Geopolitics and Gain-of-Function Research

Jan 2022 DOI 10.14302/issn.2692-1537.ijcv-21-4044

This paper attempts to present the dissemination and transmission dynamics of emerging and reemerging infectious diseases and the underlying features of gain-of-function research and geopolitics in the ambient within and across borders. Research and publication are relevant from perspectives in the management of local and global health because disease is perspicuously a geopolitical issue ostensibly linked to gain-of-function research where health diplomacy undergirds present and future global functionalities regarding the emergence and reemergence of infectious diseases. These have generated vehement reactions with propensity for extreme geopolitics and gain-of-function natural and anthropogenic activities. Geopolitical parameters and gain-of-function issues impact on the social determinants of health and vice versa. The convening and convergence of countries for unprecented epidemic or pandemic treaty settings or other formulations to confront emerging and reemerging infectious diseases will afford considerable opportunities concerning challenges in action, preparedness and response. Provisions are pertinent for legal instruments, effective and efficient systems to curb future threats and outbreaks of infectious diseases.

Serum Ferritin Level as a Prognostic Marker of 30 days In Hospital Mortality of Coronavirus Disease 2019 (COVID 19) Pneumonia at World Citi Medical Center: A Retrospective, Observational Cohort, Single Center Study

Dec 2021 DOI 10.14302/issn.2692-1537.ijcv-21-4025

Introduction The COVID-19 pandemic continues to affect a large swath of the global population. The Philippine records four hundred seventy-four thousand sixty-four (474, 064) confirmed COVID 19 cases since December 31 2020. The COVID 19 pandemic recently highlighted the role of systemic hyperferritenemia as a major cause of death. In this study, we were able to correlate the serum ferritin level and predict 30 day in hospital mortality in COVID 19 pneumonia. Objective The aim of the study is to investigate the correlation between serum ferritin level and disease mortality in COVID19 pneumonia with subset analysis on demographics and co-morbidities of patients with COVID 19 pneumonia. Methodology We reviewed the records of all laboratory confirmed COVID 19 patients from World Citi Medical Center from April 2020 up to April 2021.A statistically significant sample size of seventy nine (79) admitted patients were used in this study. A serum ferritin level was assayed using electrochemilumenescence immunoassay with a Roche COBAS analyzer. Results Result showed that high ferritin level is associated with in hospital mortality. With ferritin level of 1437.07ng/ml, poor clinical outcome and in hospital mortality was considered. We also observed that demographics and co morbidities of patients in this study were significant to predict in hospital mortality. Further sub-analysis of co morbidities such as Hypertensive cardiovascular disease, Type 2 Diabetes Mellitus, Chronic kidney disease, Liver disease, Chronic obstructive pulmonary disease and Cerebrovascular disease showed poor outcome which were directly related to ferritin levels with p value of <0.0001. Conclusion This study has demonstrated that elevated ferritin levels were shown to correlate with 30 day in hospital mortality as well as medical comorbidities such as Hypertensive Cardiovascular disease, Type 2 Diabetes Mellitus, and chronic kidney disease have shown significant evidence for in hospital mortality.

Aug 2021 DOI 10.14302/issn.2578-2371.jslr-21-3912

Background Liver disease has caused significant morbidity and mortality worldwide. Its epidemiologic and clinical pattern, however, is not well characterized in sub-Saharan countries. Objective This study aimed to describe demographic, clinical characteristics, and patterns of liver disease in a community hospital in Addis Ababa, Ethiopia. Method A retrospective hospital-based study was conducted on patients with liver disease admitted at Ras Desta Damtew memorial hospital, in Addis Ababa-Ethiopia, from February 2015 to April 2020. Result Of the total 212 patients majority, 78.8% were male, 49.1% of patients were in the age range of 31-50 with a median age of 42. The most common initial clinical presentation was ascites (87.7 %), and more than half of patients (56.6%) had a history of alcohol misuse documented on their medical charts. Chronic liver disease (cirrhosis) was found in 177 (83.5%), and Hepatocellular Cancer accounted for 7.5% of the patients. Alcohol misuse caused 45% of chronic Liver Disease, followed by Hepatitis B virus infection. Conclusion Chronic liver disease is the most common form of liver disease, and the most affected were middle-aged men. The common cause of chronic liver disease was alcohol followed by hepatitis B virus infection.

Jul 2021 DOI 10.14302/issn.2641-4538.jphi-21-3897

Background Water-related diseases are water-related disorders of the body. They are a public health problem as they are responsible for 60% of infant mortality in our developing countries. There are few studies in South Cameroon on the subject. Overall Objective of this work was to study the explanatory behavioral factors of waterborne diseases in children aged 0 to 5 years in the health area of the urban dispensary in Ebolowa in Cameroon in 2020. Methodology This was an analytical cross-sectional study comparing two groups of children (group 1: children affected by waterborne diseases group 2: children unaffected by waterborne diseases) within the health area of the Ebolowa urban area. It lasted 21 months and the study period was from 28 December 2020 to 22 January 2021. We included children aged 0 to 5 years present in households where parents/guardians gave their informed consent. Sampling was probabilistic and cluster sampling. Using the Kelsey formula, we obtained a sample of 420 households and 566 children. Data was collected using a questionnaire and stored in the Excel spreadsheet and analyzed with CDC USA's epi info software 7.2.2.6. The calculation p value was done with Stat Calc at the significance threshold of 0.05. Bold The proportion of waterborne diseases was 97% (549/566) among the children aged 0 to 5 years surveyed. The most common reasons for using the health service for children aged 0-5 years were diarrhea 78.62% (IC75.06-81.80), and malaria 78.09% (74.09-81.30). The median age of children suffering from these pathologies was 36 months (24; 60). The gender ratio (Boys/Girls) was 2.06/1. Conclusion We propose to increase the awareness of mothers/guardians on good practices; also, to increase health promotion in the fight against waterborne diseases.

Jul 2021 DOI 10.14302/issn.2574-4488.jna-21-3887

Polycystic kidney disease is an inherited disease that can lead to high blood pressure and kidney failure. In Mexico, 4.5% of patients with kidney failure are carriers of this disease; the liver is another of the organs affected by this disease that can manifest as abdominal pain and a mass effect in the abdominal cavity; we present 2 cases of polycystic kidney and liver disease (mother and child), in addition to describing the clinical manifestations, two different stages of the disease are shown, being a hereditary disease it is suggested that once a case is identified, an abdominal ultrasound is performed to first-degree relatives in search of cystic lesions to indicate preventive measures that help us preserve the overall well-being of the patient.

Adjacent Segment Disease Associated with Klippel-Feil Syndrome: A New Classification System with Corresponding Therapeutic Options

May 2021 DOI 10.14302/issn.2766-8681.jcsr-21-3783

Background Klippel-Feil Syndrome (KFS) is described as the clinical triad of short neck, low posterior hairline, and limitation of neck mobility. Objective Topresent our clinical experience with KFS patients who also had adjacent segment disease (ASD) and to propose a novel classification system for these patients. Methods This retrospective study was performed in the neurosurgery department of our tertiary care center. Data were gathered using the medical records of 22 KFS patients (10 males, 12 females) with ASD. Diagnosis was confirmed with imaging modalities including X-ray, computerized tomography, and magnetic resonance imaging. Clinical and radiological findings as well as therapeutic outcomes were noted. Results The average age of our series was 56.09 (range: 41 to 67) years. The operative technique was selected as for our novel “Yilmaz-Yucesoy Classification System”. Accordingly, one patient (4.54 %) received non-surgical treatment (Yilmaz-Yucesoy Grade 1), six cases (27.27 %) underwent anterior cervical arthroplasty, seven patients (31.81 %) underwent anterior cervical discectomy or corpectomy and fusion with cervical cage and plate (Yilmaz-Yucesoy Grade 3). Eight patients (36.36 %) with cervical spinal instability had anterior cervical discectomy or corpectomy and fusion with cervical cage and plate (Yilmaz-Yucesoy Grade 4). No mortality or remarkable complications were detected. Conclusion Appropriate and timely recognition and classification of patients with KFS and ASD based on our newly proposed “Yilmaz-Yucesoy Classification System” yielded promising treatment outcomes. However, further prospective, randomized, controlled trials are warranted on larger series to validate our preliminary results.  

Chirps Amidst Coronavirus Disease-2019 (COVID-19) Transmission and Prevention in Ethiopia in 2020

Apr 2021 DOI 10.14302/issn.2692-1537.ijcv-21-3741

Background Ethiopia confirmed its 1st case of COVID-19 on Friday 13th February 2020. The burden increased dramatically by August/2020. The conditions that led to this rise were not reviewed. Objective To exploreCOVID-19 related phenomena in Ethiopia during 2019-2020. Materials and Methods Review of journals, books, and letters to editors, e-sources, news, personal experiences, observations, and communications. Results The zoonotic source of SARS- CoV-2 (Severe Acute Respiratory Distress Syndrome- Coronavirus-2) is not confirmed. The precedent events; and exact mechanism of COVID-19 is not clear. Dynamic models were required on the time line of dynamics of COVID-19; dynamics of infectiousness of COVID-19, and mechanism of transmission of COVID-19. Incubatory carriers might have been missed. Screening based on temperature had been problematic. The time spent in the development of diagnostic test for COVID-19 might have contributed to the early spread. Uninterrupted flights to China during the epidemic by Ethiopian Airlines as well as uninterrupted domestic flights; IDP (Internally Displaced People); and others put Ethiopia (and other countries) at great risk. Demographic adjustment may not be applicable for Ethiopia due to lack of census which had to be conducted every 10 year, was conducted only in 2007. This adds to the problem of error projection. The impact of HIV (Human Immuno-Deficiency Virus Disease) and war in Ethiopia before 2000 might have had affected people who would be now old age and who would be at the most risk of death. This made the impact of COVID-19 to appear low as revealed by the lower number of COVID-related deaths in Ethiopia. There were also hesitations inconsistencies in case definitions; implementations of quarantine; and burial regulations. Conclusion Even though uninhibited foreign flight to China as well as domestic flights; inconsistencies in the implementation of regulations pertaining to COVID-19 have contributed to COVID- 19 emergence in Ethiopia, the absence of census; the demographic impact of HIV and war before 2000 might have made the impact of COVID-19 to appear low as revealed by the lower number of COVID-related deaths in Ethiopia. Recommendation Accurate and current evaluation of the impact of COVID-19 in Ethiopia may require the absence of census; demographic consequences of HIV; and war before 2000 into consideration.

Some Regulation Mechanisms of Candidate Genes for Human Cardiovascular Diseases

Mar 2021 DOI 10.14302/issn.2329-9487.jhc-21-3742

Cardiovascular disease is actually a major cause of mortality, illness and hospitalization worldwide. Several risk factors have been identified that are strongly associated with the development of cardiovascular disease. Public prevention strategies have relied predominately on managing environmental factors that contribute to cardiovascular disease, such as obesity, smoking and lack of exercise. The understanding of the role of genetics in cardiovascular disease development has become much more important to link genetics with the onset of disease and response to therapy. This seeks to examine how genes can predispose individuals to cardiovascular disease and how this knowledge might be applied to more comprehensive preventive strategies in the future. In addition, the review explores possibilities for genetics in cardiovascular disease treatment, particularly through the use of identified driver genes and gene therapy. To fully understand the biological implications of these associations, there is a need to relate them to the exquisite, multilayered regulation of protein expression and regulatory elements, mutation, microRNAs and epigenetics. Understanding how the information contained in the DNA relates to the operation of these regulatory layers will allow us not only to better predict the development of cardiovascular disease but also to develop more effective therapies.

Clinical Gastroenterological Manifestations as Criteria for the Pathology and Effectiveness of Surgical Correction of Reflux Disease of the Digestive System

Jan 2021

The presence of numerous complaints of a gastroenterocolitic nature in patients with proven NBZ and CNDP and a sharp regression of these complaints after surgical correction of NBZ and CNDP allows us to conclude that the causes of these pathological manifestations are the failure of the Bauhinia valve and chronic violation of the duodenal patency, and the most adequate surgical aid for elimination of clinical manifestations of reflux disease is bauginoplasty with simultaneous duodenojejunostomy.

Proposition and Practical Significance of Two Classes of New Teaching Methods and Diversified Assessment During the Coronavirus Disease 2019 Epidemic

Jan 2021 DOI 10.14302/issn.2766-8681.jcsr-21-3716

After entering the new century, people are facing a new external environment. Recently human society is coming into knowledge economy era, and the industrial structure has deeply been adjusted. Today, the past teaching method of imparting knowledge and getting people to accept education, or exam-oriented teaching ideas have been unable to keep up with the needs of the development of the Times. In the future, the key point of education is to promote people to understand the knowledge, and grasp rules between things. Based on this, it is particularly necessary for the talents cultivation to adopt a new idea of training. The paper takes the major in mathematics as an example, designs two classes of new teaching methods CT&CL and BOOF with the diversified assessment to cultivate students’ innovative thinking, providing a reference for the other students. The two classes of new teaching methods and the diversified assessment are worthy of further spreading and exercising during the coronavirus disease 2019 epidemic.

Statistical Analysis on the Influence of Flipped Classroom Teaching on Students’ Learning Effect During the Coronavirus Disease 2019 Epidemic

Jan 2021 DOI 10.14302/issn.2766-8681.jcsr-21-3718

Currently, many educational practitioners do not agree on how flipped classroom affects students’ learning effect. In order to further explore the impact of flipped classroom on students’ learning effect, this paper conducts a quantitative analysis of some flipped classroom experimental and quasi-experimental studies systematically by means of meta-analysis method. The study finds that the random effect model shows that the combined effect is 0.373, reaching the statistical significance level, which indicates that flipped classroom has moderate positive effect on improving students' learning effect. There is no significant difference in the effect of flipped classroom on the learning effect of different subjects and stages, but the effect on primary school students is weaker. Significant differences in the effect on learning outcomes among different knowledge types have been found, and specifically, the flipped instruction is good for the study of practical knowledge, but has less influence on theoretical knowledge learning. Therefore, in the application of flipped classroom, it is necessary to pay attention to the characteristics of different learning objects and types of knowledge, and flipped classroom teaching cannot be used too much in primary school and the teaching of theoretical knowledge during the coronavirus disease 2019 epidemic.

A Summary of Circular RNAs in Alzheimer's Disease

Jan 2021 DOI 10.14302/issn.2470-5020.jnrt-20-3619

Circular RNAs (circRNAs) are recently rediscovered eukaryotic molecules that form a covalently closed-loop structure through a special type of alternative splicing known as backsplicing. These closed-loop structures are highly stable and resistant to RNase degradation, and are thereby expressed in a tissue-specific and evolutionarily conserved manner, which regulates the expression of proteins and mRNAs that are involved in the metabolic pathways associated with specific diseases. Recent evidence of the ubiquitous expression of circRNAs in cancer under physiological and pathophysiological conditions indicates that dysregulation of gene and protein expression might promote tumorigenesis and carcinogenesis, and that circRNAs have important clinical significance in the diagnosis, treatment, and prognosis of cancer and other diseases. This review provides a brief introduction to the characteristics, formation, and function of circRNAs. Some of circRNAs act as microRNA (miRNA) sponges to regulate the level of transcriptional splicing and the expression of parental genes through the circRNA-miRNA-mRNA regulation axis. We summarize recent progress in above-mentioned circRNAs associated with Alzheimer's disease (AD).

Rare Association Between Neuroimmunological Diseases: A Possible Autoimmune Polyglandular Syndrome Type IV

Jun 2020 DOI 10.14302/issn.2641-5518.jcci-20-3370

Autoimmune polyglandular syndromes (APS) are a diverse group of clinical conditions characterized by loss of immune tolerance in various tissues. This condition can be diagnosed in childhood or adulthood, with changes in the components of the disease throughout life. Here, an unusual case of association between immune-mediated diseases will be addressed: Myasthenia Gravis, Systemic Lupus Erythematosus, and Celiac Disease. In this patient, each disease was expressed over time. Finally, we assume that this is a clinical form of APS type IV, due to the lack of thyroid involvement to date.

Molecular Study of Hepcidin HAMP (-582A/G) Gene Polymorphisms and Measurement of Serum Hepcidin Level among Sudanese Patients with Anemia of Chronic Kidney Disease

May 2020 DOI 10.14302/issn.2575-7881.jdrr-20-3343

Background Anemia of chronic disease is anemia found in certain chronic disease states, is typically marked by the disturbance of iron homeostasis or hypoferremia. Chronic renal failure is currently known as Chronic Kidney Disease (CKD) or Chronic Renal Insufficiency (CRI) implies long-standing, progressive and irreversible renal parenchyma disease resulting in diminished renal function up to 40 to 60%. Often, chronic kidney disease is diagnosed as a result of screening of people known to be at risk of kidney problems, such as those with high blood pressure or diabetes and those with a blood relative with chronic kidney disease. This disease may also be identified when it leads to one of its recognized complications such as cardiovascular disease, anemia, or pericarditis.                             Methods Sysmex kx21 used to CBC and the Cobase411 used to iron profile. Enzyme-Linked immunoassay (ELISA) was used to determine the level of serum hepcidin.  Sample preparation and PCR detection of HAMP DNA Polymorphisms: Restriction digestion of PCR products was done using Fast Digest. (Figure 1).                                                                                         Results Serum hepcidin levels higher in patients with anemia of chronic kidney disease compared with healthy controls mean. The polymorphisms of the hepcidin gene promoter in Sudanese patients with ACKD showed that the hepcidin HAMP AA genotype 70, AG 23, and GG 7 in 100 patients dialysis-dependent and AA 83, AG 17 and GG 0, and the allele A are more frequent in patients affected by ACKD. Significant statistical association observed between the hepcidin level and end-stage kidney disease. Conclusion This study evaluates for the first time the association between anemia of chronic kidney disease and hepcidin genes promoter polymorphisms and show that the hepcidin HAMP AA genotype and the allele A are more frequent in patients affected by ACKD, further investigation is needed, our data support the hypothesis and hepcidin HAMP are important in the pathophysiology of ACKD.

Care in Chronic Diseases and in "Frail" Patients in General Practice

May 2020 DOI 10.14302/issn.2692-5257.ijgp-20-3375

The world of chronicity is an area in progressive growth that involves a considerable commitment of resources, requiring continuity of assistance for long periods of time and a strong integration of health services with social ones and those requiring residential and territorial services often not sufficiently designed and developed. The fundamental aim of the treatment of chronic systems is to keep as much as possible the patient at home and prevent or reduce the risk of institutionalization. GP could put their expertise to good use in the Complex of Primary Care Units and Territorial Functional Aggregations, reducing the costs of the health service.

Medical Concepts with Clinical-Epidemiological Implications that have to be Re-Assessed Since the Coronavirus Disease 2019 (Covid-19) Pandemic

Apr 2020 DOI 10.14302/issn.2692-5257.ijgp-20-3299

The coronavirus disease 2019 (COVID-19) pandemic is something new that baffles us. The dominant health model and the theory that supported it until before COVID-19 are refuted or invalidated by observing the current tragically situation, which also implies lasting changes in that new medical model. Consequently, once the urgency of the epidemic is over, the conceptual and organizational building of medical care can no longer be rebuilt in the same way. Based on the COVID-19 experience, it is necessary to rethink what kind of knowledge can emerge. Some of the concepts with clinical-epidemiological implications that have to be re-evaluated since the COVID-19 pandemic are: 1. Large epidemics or changes do not arise from an event similar to the "Big Bang", but rather they develop slowly and underground, so a surveillance system must be instituted; 2. Re-evaluate what we understand by "evidence-based medicine"; 3. Patient-centered care is inadequate and must be replaced by community-centered care; 4. Telecare and changes in the organization of consultations; 5. Hospitals and health centers are "biological bombs" that act as vectors of disease and must change their architecture, organization and use; 6. The end of the nursing home model; 7. Change of habits; and 8. Social media can democratize information and help communities organize.

Purpose The goals of the present study were to assess the genotypic and allelic distribution of Bsm-I (rs1544410) and Apa-I (rs7975232) polymorphisms of the vitamin D receptor (VDR) gene in coronary artery disease (CAD) patients in comparison to control patients of the same age without CAD and to determine whether these gene variants are associated with dyslipidemia. Materials and Methods Based on a case-control design, 302 hospitalized patients  with CAD and 194 people of comparable age without CAD were enrolled in the study. The BsmI and ApaI polymorphisms of VDR gene were studied using polymerase chain reaction followed by restriction analysis. The allele digested by the restriction enzyme was denoted by a lower letter, whereas that not digested was indicated by a capital letter. Determination of the level of vitamin D and immunoreactive insulin in the blood serum was carried out using the immuno-enzyme method. Results The bb genotype of Bsm-I VDR gene polymorphism was detected more often in patients with CAD than in the comparison group with an increased risk of CAD by 1.52 times (p=0.006, OR=1.52(1.05÷2.2). The level of HDL cholesterol was higher in CAD patients − carriers of BB genotype compared to its level in Bb genotype carriers and bb genotype carriers (1,13±0,05 mmol/l, 1,01±0,03 mmol/l, 1,02±0,03 mmol/l respectively, p<0,05). The level of vitamin D was higher in patients with BB genotype compared to its level in bb genotype carriers (45.12±3.73 nmol / l and 34.16±1.95 nmol/l respectively, p=0.008). The occurrence of a allele of Apa-I VDR gene polymorphism was higher in patients with CAD than in the control group (p=0.02, OR=1.21(0.93÷1.57). HDL cholesterol level was higher in CAD patients - AA genotype carriers compared with carriers of Aa and aa genotypes (1.18±0.08 mmol / l, 1,02±0.02 mmol / l and 1.01±0.03 mmol/l respectively, p<0,05). Immunoreactive insulin level was significantly higher in CAD patients – aa genotype carriers. No differences in LDL cholesterol and triglycerides were found. Vitamin D level was lower in CAD patients - Aa and aa genotype carriers (33,8±33,9 nmol/l ,p=0,02 and 24,7±4,9 nmol/l, p=0,05 respectively in comparison to vitamin D level = 43,3 ±4,2 nmol/l in AA genotype carriers). Conclusion The bb genotype of Bsm-I VDR gene polymorphism is associated with an increased risk of CAD. A carriage of b allele in CAD patients is associated with lower level of vitamin D and HDL cholesterol. A carriage of a allele of Apa-I VDR gene polymorphism in CAD patients is associated with lower level of vitamin D and HDL cholesterol.  

Urgent Prevention of Corona Virus Disease 2019 (COVID-19): Chinese Eating and Mask-Wearing Cultures

Mar 2020 DOI 10.14302/issn.2641-4538.jphi-20-3264

Chinese people have a very good mask-wearing culture; it is normal to wear masks to protect their faces from wind and pollution. Thus, they easily accept the wearing of masks to prevent infectious diseases, as seen with the Corona Virus Disease 2019 (COVID-19) in China today. However, Chinese people have a dangerous eating culture: they share foods or soups from the same bowls and pots using their personal chopsticks/spoons and emphasize loud talking when eating at banquets or at homes. We think this eating culture has raised the infection risk of COVID-19 from person to person by contamination. Therefore, in this paper, we propose models to elucidate how people are infected with COVID-19 through droplet transmission when eating with Chinese cultural context to address the urgent need to change Chinese eating culture; we believe these study models can help not only the Chinese people, but also other national people, to raise mindfulness of public health, prevent COVID-19 and other infectious diseases, at the present pandemic and in the future.

Feb 2020 DOI 10.14302/issn.2470-5020.jnrt-20-3226

Charcot Marie Tooth disease is a is a very chronic progressive hereditarymotor and sensory neuropathy characterized by progressive weakness andloss of touch sensation across various parts of the body. There are no curative or effective medical therapies that can ameliorate the disability associated with Charcot Marie Tooth disease. The aim of this paper is to describe the safe novel use of cerebrolysin in an Iraqi patient with Charcot Marie Tooth disease. Patients and Methods A boy who was born on the seventh of November, 2009, and was first seen on 29th of January, 2018 at the Children Teaching Hospital of Baghdad Medical City and had Charcot Marie Tooth disease was observed. He had difficulty in walking and abnormal gait that made him left first grade primary school. The nerve conduction study and electromyography study supported the clinical diagnosis of chronic symmetric sensori-motor polyneuropathy of moderated severity. The boy was treated with a safe novel therapy for one month. He receivedten doses of 3 ml intra-muscular cerebrolysin every three days. Results The short term effect of the therapy was dramatic with noticeable improvement that has never been reported before with this condition. Conclusion Further studies enrolling more patients are highly recommended.

Implementation of an Elemental Diet in Five Children Diagnosed with Autism Spectrum Disorder Presenting with Gastrointestinal Disease: A Brief Report

Feb 2020 DOI 10.14302/issn.2379-7835.ijn-20-3181

Autism Spectrum Disorder (ASD) is a developmental disorder characterized by impaired communication and social interaction. Children with ASD are frequently diagnosed with gastrointestinal (GI) issues, including inflammatory bowel disease (IBD), gastroesophageal reflux, abdominal pain, diarrhea, and constipation, although the association between ASD and GI conditions is unclear. Underlying nutritional deficiencies are more common in children with ASD, and increase the risk of them developing medical conditions secondary to the behavioral diagnosis. This objective of this study was to examine the use of an elemental diet (ED) in the treatment of gastrointestinal disease in 5 children with ASD ages 2-21 years of age. In the study participants, the ED was well-tolerated with improvements in anthropometric measures, nutritional markers, and/or GI functioning reported after 12 weeks of intervention. Further research to advance the development of specific evidence-based guidelines in the management and treatment of gastrointestinal concerns in the ASD population is warranted.

Nutritional Care for Patients with Ebola Virus Disease in Ebola Treatment Units – Past and Current Experiences from Practitioners

Nov 2019 DOI 10.14302/issn.2379-7835.ijn-19-3083

Background In November 2014, the World health Organization (WHO), in collaboration with United Nations Children's Fund (UNICEF), and the World Food Programme, produced interim guidelines (iGL) on providing nutritional support to patients in Ebola treatment units (ETUs). They have been translated into French and issued by the Ministry of Health, UNICEF and WHO in adapted versions to be used in the current outbreak in the Democratic Republic of the Congo (DRC). This paper evaluates the use and usefulness of the 2014 iGL in the West Africa and current DRC Ebola virus disease (EVD) outbreaks and identifies experiences and lessons learned from practitioners on the operational aspects of nutritional care and support in ETUs. Methods Key-informants (n=26), from 12 organizations (Non-Governmental Organizations, United Nations, Red Cross Red Crescent Movement) were interviewed who were actively engaged in the nutritional and/or clinical care of EVD patients. Results There was a consensus among key-informants that the 2014 iGL initially served a guiding purpose. However, the vast amount of learning from the 2014-2016 and current EVD outbreaks indicates that the interim guidelines need to be revised. Practitioners struggled to find operational solutions for nutritional care, and the challenges were plentiful, especially regarding 1) the different perceptions of the importance of nutritional care among ETU staff; 2) the difficulties around food preparation and distribution for EVD patients; 3) how to take into account the patients’ dietary preferences; 4) the nutritional care needed in relation to specific EVD symptoms; 5) who assumed roles in nutritional care in ETUs; 6) if and how feeding support was organized; 7) whether malnutrition needed to be addressed and how; and 8) whether the intake of specific nutrients could contribute to improved treatment outcomes.  Information from the key-informants interviews resulted in numerous lessons learned and recommendations for nutritional support during current and future outbreaks. Conclusions This investigation underscored the importance of documenting experiences of practitioners on nutritional care in emerging infectious diseases for which limited scientific evidence exists and for which interim guidelines are produced to fill in knowledge gaps. It also emphasized the importance of nutritional care in ETUs during treatment.

Capsaicin: A Potential Therapy Adjuvant for Intestinal Bowel Disease

Nov 2019 DOI 10.14302/issn.2574-4526.jddd-19-3063

Most of the patients with inflammatory bowel disease avoid pepper or spicy food, alleging that this condiment causes anal sensation of burning and accelerates intestinal movements. Capsaicin is the main bioactive component of peppers responsible for the pungent flavor that characterizes red peppers. Capsaicin has been related to several biological effects, including decreased body fat, antianti-inflammatory, anticarcinogenic, antioxidant activites and modulator of intestinal motility. These actions mostly are due to its role as an agonist of the transient receptor potential vanilloid 1 (TRPV1), expressed in the mesenteric nervous system and epithelial cells of the colon. Nonetheless, the anti-inflammatory action of capsaicin is also related to its role in activating the peroxisomal proliferator-activated receptor gamma (PPAR-γ). Topical capsaicin formulations are already used for pain management, but oral administration of capsaicin is rare. Here, we discuss the main actions of capsaicin that could interfere with the symptoms and severity of IBD. Although animal experiments suggest a beneficial effect of capsaicin on colitis, clinical studies exploring the potential analgesic and anti-inflammatory of capsaicin on Crohn or Ulcerative Colitis are scarce. We concluded that there is no evidence that capsaicin aggravates IBD symptoms or severity. On the opposite, experimental studies suggest that capsaicin could reduce intestinal inflammation by a mechanism that could involve not only the TRPV1 receptor but also PPAR γ. However, clinical studies are still scarce, and data regarding capsaicin concentrations, routes of administration, and long-term side-effects need to be better understood before its use.

Comparison of Dipper and Non-Dipper Hypertension Patterns According to Chronic Kidney Disease Stage

Sep 2019 DOI 10.14302/issn.2574-4488.jna-19-3008

Introduction Hypertension is a major cardiovascular risk factor. There is a strong relationship between blood pressure (BP) elevation and stroke, myocardial infarction, heart failure and mortality due to kidney disease. It is known that the loss of the dipping pattern in hypertension is associated with increased target organ damage. In our study, we aimed to investigate the prevalence of dipper hypertension (DHT) and nondipper hypertension (NDHT) and related factors in patients with stage 1 and 2 chronic kidney disease (CKD). Materials and Methods A total of 158 patients diagnosed with stage 1 or stage 2 CKD were included in the study. Demographic characteristics, anthropometric measurements, physical examination findings and laboratory results of the patients were recorded. Ambulatory BP monitoring was performed in all patients. Results Of the 158 patients (female n: 98), 78 (49%) were in the stage 1 CKD group and 80 (51%) were in the stage 2 CKD group. No significant difference was observed in the prevalence of DHT or NDHT between hypertensive patients in the stage 1 and 2 CKD groups. The rate of NDHT was 59.5% (94/158 patients). Female patients had more DHT in the general population and in the stage 1 group than male patients (p=0.05, p=0.01, respectively). Conclusion No significant difference was observed in the prevalence of DHT or NDHT between hypertensive patients in the stage 1 and 2 CKD groups. The prevalence of DHT in female patients was significantly higher in both groups than in men in both groups, but especially in the stage 1 CKD group.

Severe Infantile Blount’s Disease in Kumasi, Ghana: A Case Report

Sep 2019 DOI 10.14302/issn.2474-3585.jpmc-19-3009

Blount’s disease, also known as tibia vara, is a developmental disorder involving the posteromedial proximal tibial physis resulting in progressive varus, procurvatum and internal torsion of the affected tibia 1. The condition was first published by Blount in 1973 2. The aetiology of this disease is unkown. However, associations exist between blount’s disease and the Afro-Caribbean race, early age of walking and obesity 34. Furthermore, genetic predisposition has been postulated as well as mechanical loading of the physis 456. Affected children are usually overweight and start walking early. It is bilateral in 80% of cases 7.

Rosenthal's Disease (Hemophilia C or factor XI Deficiency) Revealed by Chronic Epistaxis: The First Observation in Sub-Saharan Africa.

Aug 2019 DOI 10.14302/issn.2372-6601.jhor-19-2982

Objective Rosenthal's disease (RD) is a rare constitutional hemorrhagic disorder defined by factor XI deficiency. It is clinically characterized by the presence of minimal haemorrhage. We report the first observation of RD in Togo. Observation Mrs. G. A., 45 years old with no particular pathological antecedents, was referred for anemia in a context of chronic epistaxis. It was a spontaneous anterior exteriorization epistaxis often of great abundance, rocking and which evolved episodically. The patient received several transfusions for anemia. The ear-nose-throat examination was normal and a sinus CT scan found only an inflammatory process of the right maxillary sinus. The blood count showed microcytic severe anemia (2,2g/dl). Hemostasis tests showed a prolonged aPTT (57,9 seconds). Clinical examination documented an anemic syndrome with dry skin. Iron deficiency was found. The hemostasis balance confirmed aPTT elongation. Coagulation factors activity showed normal VIII and IX level, but moderate decrease of factor XI (32%). The family survey was not possible (orphan patient). It is recommended the setting under fresh frozen plasma (FFP) in case of a new episode. Follow-up is in progress. Conclusion In the event of any hemorrhagic syndrome, the isolated elongation of the aPTT must lead to a systematic analysis of intrinsic pathway factors

Jun 2019 DOI 10.14302/issn.2374-9431.jbd-19-2788

Purpose The goal of this study is to determine the association of L162V polymorphism of PPAR-alpha gene, A603G polymorphism of tissue factor gene and the risk of coronary heart disease development in Russian population.   Materials and Methods A clinical and genetic study of 414 patients with CHD and 220 people of comparable age without CHD which amounted to a control group was performed. L162L and L162V genotypes of L162V polymorphism of PPAR-α gene, A603A, A603G and G603G genotypes of A603G polymorphism of tissue factor gene were determined by polymerase chain reaction followed by restriction analysis. Results A carriage of L162V genotype and V allele of PPAR-α gene was associated with an increase risk of CHD in 2,13 times (L162V genotype) and in 2,21 times (V allele), with an increase in risk of CHD before the age of 45 years in 4,68 times (L162V genotype) and in 3,88 times (V allele). Significantly higher in patients with CHD compared with the general population and in patients with a carriage of G603G genotype and G allele of tissue factor gene was associated with the increase of CHD risk in 2,68 times (G603G genotype) and in 4,37 times (G allele), occurred more frequently in patients with debut of disease at age of 45 years and younger. The level of tissue factor was significantly higher in patients with CHD – carriers G603G genotype compared with carriers A603A genotype (217,9±15,2 pg/ml and 152,6±30,4 pg/ml, respectively, p=0,04). A carriage of the combination of L162V and G603G genotypes was associated with an increased risk of CHD in 3,04 times. Conclusion A carriage of V allele of L162V polymorphism of PPAR-α gene and G allele of A603G polymorphism of tissue factor gene, as well as their pair combination are associated with an increased CHD risk, especially at age 45 years or less.

Lyme Disease: In the “Lime Light” for Over 25 Years

Jun 2019 DOI 10.14302/issn.2640-690X.jfm-18-2067

Lyme disease has been a topic of debate practically since its discovery in the 1970’s. The hot topic is whether or not long-term antibiotics should be used for Lyme disease patients with persistent symptoms. The source of such a long-running debate stems from the difference in opinions over the cause of long-term, persistent symptoms after treatment in some patients. Toward its end, Medicine has finally begun to embrace the existence of Chronic Lyme Disease, but changes still need to be made in the future.

Cardiac Inflammatory Pseudotumors in Behçet’s Disease

May 2019 DOI 10.14302/issn.2329-9487.jhc-19-2787

Introduction Cardiac non-specific inflammatory pseudotumors (NSIPT) are exceptionally associated to Behçet's disease (BD) and represent a real diagnostic and therapeutic challenge. The meaning and the mechanisms of this association are not yet well understood. The purpose of this paper is to study the epidemiologic, therapeutic, and evolutionary characteristics of cardiac NSIPT during BD Methods Systemic review of all reported cases of cardiac NSIPT associated with BD. Results We found only 6 cases of NSIPT associated with BD. Of these six patients, 4 were men (66.66%) and 2 were women (33.33%): Sex ratio =2. The average age was 26.66 years (9-35 years). The pseudotumor was unique in all cases. The chronology of occurrence of these NSIPT compared to the underlying angiitis was variable: inaugural of the disease in 4 cases, and complicating a previously known BD in 2 cases. The surgery was performed in all cases. It was carried out for diagnostic purpose in 4 cases, and therapeutic in the other 2. Additional medical treatment based on systemic corticosteroids with or without immunosuppressants was indicated in 4 patients. The evolution was favorable in 5 cases and a single case was quickly fatal. Recurrence of NSIPT was reported in one patient (20%). Conclusion The results of this review suggest a very likely association between BD and cardiac NSIPT; especially because of the scarcity of these two conditions in the general population, and the epidemiological characteristics clearly different from those of cardiac NSIPTs in the general population. The pathogenic mechanisms common to these two conditions (immune, inflammatory, reactive, and vascular) reinforce this causal link. The main differential diagnoses of these pseudotumors during BD remain cancer and intracardiac thrombosis.

Cardiovascular Disease and Depression/Anxiety, Two Complication of Menopause Status

Apr 2019 DOI 10.14302/issn.2379-7835.ijn-19-2579

Objective Postmenopausal women are at an increased risk of Cardiovascular Disease. We aimed to investigate whether this risk differed between individuals with a naturally occurring and other reasons for menopause within a large population-based Iranian sample. Study Design A total number of 1763 postmenopausal women (defined by amenorrhea for more than a year, or FSH > 30-40 mIU/ml), 900 of them with a natural menopause and 863 of them with other reasons for menopause caused by (hysterectomy without oophorectomy or one side oophorectomy, hysterectomy with oophorectomy or two side oophorectomy without hysterectomy) were recruited as part of the Mashhad Stroke and Heart Atherosclerotic Disorders (MASHAD) cohort study. Biochemical and hematological risk factors were measured in all the subjects and the data were analyzed by SPSS software version 20 Results There was a significant difference in the presence of cardiovascular disease in the natural menopause group compared with other reasons for menopause group (p<0.05). There was also a meaningful difference between the prevalence of depression and anxiety in the natural menopause individuals compared with other reasons for menopause group (p<0.05). Discussion High prevalence of CVD, depression and anxiety in other reasons in menopause women were observed among Mashhad urban females. It should be considered as a noticeable message. Furthermore, studies are necessary to determine different parameters between evaluating CVD, depression and anxiety among menopauses women.

Massive Left Atrium from Severe Mitral Stenosis due to Rheumatic Heart Disease: Clinical Images Not Usually Seen in Modern Radiology and Ultrasound

Apr 2019 DOI 10.14302/issn.2641-5518.jcci-19-2700

Rheumatic heart disease is becoming far less common in the developed world, and therefore expsoure to its complications are been seen less by clinicians. With the increasing ease of world travel, patients with less commonly seen medical conditions are increasingly presenting to Hospitals requiring management of their complications. We present a case of an elderly lady who was a tourist in Australia, who presented with complications of her rheumatic heart disease, and her subsequent radiological and echocardiographic investigations were a significant surpirse for her treating clinicians.

Early Prediction of Alzheimer’s Disease Using OCT Imaging Technique

Apr 2019 DOI 10.14302/issn.2998-4211.jalr-19-2658

Alzheimer’s Disease (AD) is one amongst the overwhelming types of dementia that distresses the brain nerve cells leading to a perpetual loss in memory and creating a lot of difficulties for the family members in caretaking. The prediction of the disease at an earlier stage is a common problem. The most prevalent imaging modalities used for diagnosing AD are Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT). They can provide valuable information regarding the changes in internal and external brain regions and activities for diagnosing AD. But the relevant studies made on retina reveals that in addition to brain changes there are some variations on the retina layers of the AD patients. Therefore, the retina can be used as a biomarker for diagnosing AD. There are different techniques available for an eye examination. Most noticeable of them are Fundus Imaging and Optical Coherence Tomography (OCT). In this paper, we have focused on OCT retinal images of AD patients for the early diagnosis of AD.

Lung Cancer and Isolated Adrenal Metastases: Different Disease?

Mar 2019 DOI 10.14302/issn.2642-9241.jrd-18-2499

Distant metastases generally indicate disseminated disease and the standard treatment for these patients is palliative chemotherapy. Retrospective series showed that selected patients with metastatic lung cancer and a solitary extrathoracic disease could be effectively treated with curative intention by resection of both primary tumor and the single site of metastatic disease. According to current data, adrenalectomy might be considered as an alternative option for patients with isolated adrenal metastases. Significant morbidity and mortality may be happened by these procedures, and a cautious analysis of pros and cons should be discussed with the patient. We present a review of the literature and updated recommendations focusing lung cancer with solitary adrenal metastasis.

Reduction of Side Effects by Segmented Electrodes in Case of Subthalamic Nucleus Deep Brain Stimulation in Parkinson Disease: A Case Report.

Mar 2019 DOI 10.14302/issn.2470-5020.jnrt-19-2630

Patients suffering treatment resistant Parkinson´s disease (PD) are potential candidates for deep brain stimulation (DBS). Commonly most implanted electrodes have a cylindrical shape with quadripolar electrode contacts and generate a symmetrical stimulation field around the lead. To reduce side effects through activation of neighboring fibers a new electrode design with segmented contacts was developed and enables a better adaption of the field of stimulation as well as a multi-target stimulation to improve therapeutic benefits. We report about a 51-year-old male patient with a 15-year history of treatment-refractory PD, who was implanted with bilateral segmented electrodes in the subthalamic nucleus (STN) with St. Jude Medical Infinity™ DBS System (Abbott/St. Jude Medical, Saint Paul, Minnesota, USA). Despite a clear mood-enhancing effect, stimulation with ring electrodes caused motor side effects including rigor and speech disorder. With segmented electrodes an effective and gentle stimulation was achieved. The stimulation of the anterior segments in the central position of the electrode in the STN showed no side-effects and allowed a reduction of initial symptoms in an low stimulation amplitude. Despite precise preoperatively planning and intraoperative trial stimulation, side effects of STN stimulation are very common. The application of segmented electrodes permits more options to reduce side effects rather than using ring electrodes. Studies with larger sample sizes are needed to establish the optional DBS electrode.

Robust Sampling of Defective Pathways in Parkinson Disease

Jan 2019 DOI 10.14302/issn.2641-5526.jmid-18-2529

Discrimination of case-control status based on gene expression differences has potential to identify novel pathways relevant to neurodegenerative diseases including Parkinson’s disease (PD). In this paper we applied two different novel algorithms to predict dysregulated pathways of gene expression across several different regions of the brain in PD and controls. The Fisher’s ratio sampler uses the Fisher’s ratio of the most discriminatory genes as prior probability distribution to sample the genetic networks and their likelihood (accuracy) was established via Leave-One-Out-Cross Validation (LOOCV). The holdout sampler finds the minimum-scale signatures corresponding to different random holdouts, establishing their likelihood using the validation dataset in each holdout. Phenotype prediction problems have by genesis a very high underdetermined character. We used both approaches to sample different lists of genes that optimally discriminate PD from controls and subsequently used gene ontology to identify pathways affected by disease. Both algorithms identified common pathways of Insulin signaling, FOXA1 Transcription Factor Network, HIF-1 Signaling, p53 Signaling and Chromatin Regulation/Acetylation. This analysis provides new therapeutic targets to treat PD.

The Current Immunoassays and Emerging Immunogenomic Approaches for Immunomonitoring Cancer and Infectious Diseases

Jan 2019 DOI 10.14302/issn.2572-3030.jcgb-18-2527

As remarkable advances have been made in immunotherapies, the overall goal of immunotherapy has become the selection of patients and evaluating the benefits of treatment. One of the major obstacles to develop immunotherapies is the lack of effective immune monitoring. Monitoring of key changes in the immune system during immunotherapy (immunomonitoring) provides important insights into efficacy as well as the immune mechanisms of response at the molecular and cellular levels. Immunomonitoring techniques include traditional immunoassays that use specific antibodies to recognize the analytes of interest, new high-throughput immunoassays that target immune cells and nucleic acids, and less classical immunogenomic approaches that rely on genome-wide profiling and computational analysis on various types of clinical samples. Substantial progress has been made in the application of immunomonitoring strategies to pre-clinical and clinical studies, especially for patients with cancer and infectious diseases. Current and emerging immunoassays performed in clinical practice will be examined herein, and immunogenomic approaches that complement these techniques will be highlighted and compared with traditional methods. Finally, we will discuss several new computational methods for analyzing gene signatures for immunomonitoring, including gene expression data profiling by microarray, the nCounter technique, regular RNA-seq, and single-cell RNA-seq. Novel immunomonitoring techniques, especially immunogenomic approaches, will continue to be developed to facilitate assessment of immunotherapeutic response and predict patient outcomes in cancer and infectious disease.  

Synthesis and Analysis of Copper Neem (Azadirechta Indica) Soap-Nitro and Ethoxy Benzothiazole Complexes for Anti-Bacterial Activity Related with Skin Diseases

Dec 2018 DOI 10.14302/issn.2328-0182.japst-18-2522

The solid copper(II) soap derived from Neem (Azadirechta Indica)oil and its complex with ligand containing nitrogen, sulphur and oxygen atoms like 2-amino -6-nitro benzothiazole and 2-amino- 6-ethoxy benzothiazole have been synthesized and characterised by elemental analysis, IR spectroscopy and biological studies. From the analytical data, the stoichiometry of the complex has been observed to be 1:1 (metal:ligand). The derived compounds were found active against Staphylococcus aureus,Coagulase-negative staphylococci (CoNs), Acinetobacter baumanii, Pseudomonas aeruginosa and micrococcus bacteria. These findings have high medical, industrial and economic significance as copper (II) soap and copper (II) soap complex could be harnessed in the formulation of medicated soaps.

Intestinal Malrotation in a Suspected Celiac Disease Patient: A Case Report

Nov 2018

Intestinal malrotation is the incomplete rotation of the midgut during embryogenesis. The reported prevalence is 1 in 500 live births, however some studies report a prevalence as high as 1% of the population1, 2. Traditionally it is though as a disease of the pediatric population presenting as bilious emesis during the first year of life but can present with different symptoms even in adulthood. Presentation in older populations tends to be atypical, chronic abdominal pain, nausea and diarrhea being the most commonly reported symptoms 3. However, as these symptoms accompany almost all-gastrointestinal pathology it is difficult to determine if abnormalities of rotation and fixation of the intestine are the cause for the symptoms in a given patient given its relative rarity. It therefore is important to have a high index of suspicion in patients with non-specific gastrointestinal symptoms. We report laparoscopic management of a patient with abnormal rotation/fixation who was treated for many years as celiac disease (CD). Celiac disease is an immune mediated systemic disorder elicited by gluten in genetically susceptible individuals4. It can present as chronic abdominal pain, chronic diarrhea, failure to thrive, weight loss, stunted growth, distention and fatigue. His symptoms immediately resolved after surgery.

Short-Term Outcomes of Deep Brain Stimulation of the Subthalamic Nucleus in Patients with Parkinson’s Disease - Pilot Study

Sep 2018 DOI 10.14302/issn.2470-5020.jnrt-18-2185

Background: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) provides efficient treatment for the alleviation of motor signs in patients with Parkinson's disease (PD), but more studies about gait and functionality are needed. We aimed to understand whether short-term DBS treatment will can relieve the symptoms of PD patients, specifically we examined its effect on motor-cognitive-complication parameters, fine motor skills and daily living activity (DLA) of these patients. Method: Ten patients from Mustafa Kemal University Neurosurgery Department were recruited. The assessments were made twice, first time preoperatively, which was within one week prior to the surgery, second time postoperatively, which was 55-65 days post treatment. The motor scores, DLA scores, mental scores and complication scores were measured with Unified Parkinson's Disease Rating Scale (UPDRS), fine motor skills measured with The nine-hole peg test (9-HPT), balance measured with Berg Balance Scale (BBS) and falling risk measured with Timed Up and Go Test (TUG). Results: 10 patients (5 female, 5 male) aged between 40-60 (mean=49.44±6.69 years) were included in the study. Duration of the disease’s mean was 5.60 years. We found significant difference between pre-op and post-op results in UPDRS DLA, UPDRS motor, UPDRS complication, UPDRS total score and TUG tests (Table 2). There was no significant difference between preop-postop assessment in UPDRS mental, BBS and 9-HPT results (p>0.05). Discussion: Balance, walk and fine motor impairment occurs almost always in Parkinson’s disease and resulting in difficulties with daily living activities. We found that DBS has positive effect on PD complications, balance and walking abilities. PD patients that have falling risk and multiple motor symptoms may have benefit from DBS.

Association between Sclerosing Cholangitis and Paget Disease: Diagnostic Difficulties

Sep 2018 DOI 10.14302/issn.2578-2371.jslr-18-2174

A rare case of association between primary sclerosing cholangitis and Paget's disease emphasizing the diagnostic difficulties in front of increased alkaline phosphatase is reported. The association between sclerosing cholangitis and Paget's disease wasn’t yet described and could thus be coincidental. However, our observation underlines the benefit of dosing ALP isoenzyme to characterize the bone or hepatic origin of ALP and therefore, help to guide the diagnosis.

Evaluation of Co-morbidities among Different Chronic Obstructive Pulmonary Disease Phenotypes

Aug 2018

Background: Co-morbidities are associated with increasing risk of mortality, hospitalizations and costs of treatment in Chronic Obstructive Pulmonary Disease patients. Identification of Co- morbidities related to COPD phenotypes may guide individualized therapies and achieve better prognosis. Methods: A prospective study of one hundred ten patients of confirmed COPD diagnosis were carried out and divided into five different phenotypes with related co-morbidities. History taking, clinical examination, Chest X-ray, Computed chest Tomography, laboratory investigations, arterial blood gas, Echocardiography and Electrocardiography were done for all patients. St. George’s Respiratory Questionnaire, COPD assessment test (CAT score) and BODEx (BMI, FEV1, dyspnea and exacerbations) were used for assessment of disease impact on quality of life, severity, and exacerbation respectively. Results: Emphysema group were 31% among all cases with mean age 61.8±9.1, frequent exacerbator group and Chronic bronchitis phenotype were 18% with mean age 64.4±11.3, and 48.8±9 respectively. COPD with bronchiectasis group were 19% with mean age 60.3±6 and Asthma COPD Overlap Syndrome (ACOS) were 12% with mean age 62.8±15.8. There was significant difference as regards age between different group of phenotypes P- value <0.001. There was significance difference in BODEx index and in (CAT) score among different COPD phenotypes P-value 0.020, 0.001 respectively. There was significant difference in all items of SGRQ among different COPD phenotypes P–value 0.001. Diabetes was commonly presented in 50 % ACOS cases, Ischemic heart disease was present more in Emphysema 22.9%, Osteoporosis was more in COPD with bronchiectasis 28.6%, Cor-pulmonale was more present in frequent excerbator 65%, and Anemia more common in COPD with bronchiectasis 23.8%. Depression was more common in frequent excerbator phenotype (45.0 %). Gastro-esophageal reflux was the most common co-morbidities (58 %) then cor-pulmonale 41.8%, systemic hypertension 40 % and pulmonary hypertension 28%. Conclusion: The presence of significant co-morbidities is important modifying risk factors for severity in COPD. They contribute to the overall severity in individual patients, have a major impact on quality of life, and major causes of hospitalization. Co-morbidities can be associated with any clinical phenotype.

Human Proteome Project and Current Bioinformatics Status in Disease Diagnosis and Treatment

Apr 2018 DOI 10.14302/issn.2326-0793.jpgr-18-2004

Human proteome project was revolutionized about 40 years ago with purpose of summarizing whole proteomic data at one place. It was launched after human genome project to map and observe all proteins. The goal related proteomic study is to draft the entire human proteome in disease diagnosis by using bioinformatics tools. Pillars of human proteome project provide different databases related to proteins at transcriptional and translational level. Human proteome organization(HUPO) published biology disease HUPO whose aim is to measure protein and proteome by life and processes related to human diseases. Different human organ like plasma, liver, brain and diabetic base project are used to characterize human disease and health. Major data resources accumulated in databases like peptides Atlas, GPMDB and neXtProt for proteins. Matrices of human proteome project identify and characterize the protein products as Post translational modification (PTM), splice various isoforms from 20,300 proteins. Matrices related to different years make proteomes counterpart by magnify the research biomedical community with high output of instruments and specimen pre-analytical protocols. CALIPHO multidisciplinary group provides information about protein complexities, interactions, function and structure complexities after Uniport and Swissprot. Different bioinformatics tools are used for structural and functional annotations of protein, disease diagnosis and mutations due to protein. Extensive study of human proteome project has been proved helpful in disease treatment at translational and post- translational levels. In future, human proteome project along with bioinformatics will include protein profiling, biomarkers, Mass spectrophotometer technique and cross analysis of different proteome projects.

Chagas Disease in Dogs

Jan 2018 DOI 10.14302/issn.2575-1212.jvhc-17-1817

Chagas disease is zoonotic illness or an anthropozoonosis caused by flagellated protozoan parasite Trypanosoma cruzi. This infection presents alarming rates of incidence/prevalence, for this reason, is recognized worldwide as one of the 13 most neglected tropical diseases 1. Numerous studies have demonstrated the existence of domestic dogs infected with T. cruzi across endemic areas ranging from southern United States of America to Argentina 2. The reported prevalence varies widely (1.42-92%), depending on ecoepidemiological and sociocultural factors 3. It is important to emphasize that the natural infection in dogs with T. cruzi occurs in the same way as in humans, that is to say, through active transmission by vectors, contamination by feces infected with the parasite through wounds or the conjunctiva, can also occur by ingestion of infected vectors or tissues of wild animals present in the peridomicile or home 4. The transplacental transmission is also an important mode of transmission in dogs 5. Nevertheless, the main mode of transmission in canine species seems to be the ingestion of infected vectors 6. During the life cycle of T. cruzi the trypomastigotes present in the heces of the triatomines are introduced in the mammalian host by  contamination of the insect bite or mucosal membranes. The metacyclic form can penetrate a variety of phagocytic and nonphagocytic nucleated cells. Once inside the cells the parasite becomes in amastigote, which are multiplicative forms that divide into cells. Due to the high parasitic load they produce the lysis of the cells and escapes into the cytoplasm. The amastigotes transform to slender trypomastigotes which can invade adjacent cells, this forms can be ingested by triatomines and they transform into epimastigotes Finally, after migration to the bug's hindgut, the epimastigotes differentiate into infectious metacyclic trypomastigotes, in this way the life cycle of this microorganism is completed 7.

Anti-DPPX-Encephalitis in A Patient with Cerebral Vasculitis and Connective Tissue Disease

Jan 2018 DOI 10.14302/issn.2470-5020.jnrt-17-1926

Since the first description in 2013, 39 cases of anti-DPPX-encephalitis have been described. Main features of this autoimmune encephalitis characterized by antibodies against the potassium-channel-associated regulatory protein DPPX are gastrointestinal symptoms, cognitive dysfunction and signs of CNS hyperexcitability. While the majority of patients responds to immunotherapy relapses are frequent and often successfully treated with rituximab. Here we report another case of anti-DPPX-encephalitis presenting with the above mentioned triad. However, this is the first case of anti-DPPX-encephalitis in the context of a connective tissue disease combined with cerebral arteriopathy along with brain parenchymal lesions that we interpreted as a secondary, CTD-associated cerebral vasculitis. While the latter resolved under immunosuppressive treatment, comprising glucocorticosteroids, cyclophosphamide, rituximab and plasmapheresis, deterioration of the CTD and multiple infectious complications finally led to the patient's death. As histological evidence for cerebral vasculitis is lacking, other differential diagnoses for the observed cerebral arteriopathy, especially reversible cerebral vasoconstriction syndrome, have to be considered.

Advanced Virological And Clinicopathological Studies On Cattle Suffering From Foot And Mouth Disease Virus

Sep 2017 DOI 10.14302/issn.2577-137X.ji-17-1736

Some strains of Foot and mouth disease virus (FMDV) are endemic in Egypt. The present study was performed on cattle and buffaloes (ages: 3 months up to 1.5 years old, of years 2015 and 2016), which were suffering foot and mouth disease (FMD). Sera and tissues samples were tested by different techniques including serum and virus neutralization tests (SNT, VNT), virus isolation and identification by tissue culture methods, Enzyme linked immune-Sorbent Assays (ELISA); and by the pathological and hematology techniques. The results showed the predominance of FMDV serotype O with the presence of serotypes SAT2 and A. The results showed the pathologic picture of FMD was similar regardless its specific subtypes, as apparently the studied strains produces same pathological and hematological changes. Microscopic examination reveals severe hydropic degenerations and necrosis in most affected organs, accompanied by significant changes in blood parameters which indicate severity and direct effects of FMDV on the hematopoietic system. These findings indicates the mode of pathogenesis of FMD virus in its way to exhibits the characteristic symptoms of illness. However, the investigation showed the presence of FMDV type O, A and SAT2 in the studied areas of delta governorates. It is important to focus on producing of vaccines which have only these serotypes as solution to get rid of the endemic behavior of FMDV in delta of Egypt.

Development of a Chronic Obstructive Pulmonary Disease Severity Classification System Using A Japanese Health Insurance Claims Database

Sep 2017 DOI 10.14302/issn.2474-7785.jarh-17-1727

Background: Healthcare services provided to patients should vary depending on disease severity. However, disease severity bias, a type of selection bias, is a commonly encountered problem in administrative database studies. Herein, we selected chronic obstructive pulmonary disease (COPD), which commonly affects elderly Japanese citizens, for the development and validation of a severity classification system based on a health insurance claims database. Methods: Patients who received COPD-related diagnostic codes in 2011 were selected from a commercially based health insurance claims database. COPD patients were randomly divided into two groups to develop and validate severity scores. A principal component analysis was used to estimate factor loadings used to weight calculations of COPD severity scores. Score validity was evaluated using a linear trend test to predict COPD treatment costs and acute exacerbation events. Results: Using records from 880 patients, ten variables were created: acute exacerbation events, emphysema diagnoses, laboratory test and oxygen therapy procedures, prescribed anticholinergic, inhaled corticosteroid (ICS), short acting beta-agonist, and long acting bronchodilator (LABA) agents, asthma diagnosis and patient birth years. Factor loadings from LABA and ICS prescriptions had the strongest impacts on estimated severity scores (0.50 and 0.49, respectively). Among 300 validation group patients, scores were found to associate with increasing trends of median costs and exacerbation risks (p for trend < 0.05). Conclusions: Estimatedseverity scores would help to predict COPD-related medical costs and exacerbation events. For further clinical implementation, this classification system should be re-evaluated using clinical lung functions information indicative COPD severity and treatment choices.

A Model for Identifying Actionable Findings on Computed Tomography in Crohn’s Disease Patients in the Emergency Department

Aug 2017 DOI 10.14302/issn.2574-4526.jddd-17-1688

Patients with inflammatory bowel disease (IBD) frequently visit the emergency department (ED). The use of cputed tomography (CT) scans in this population has drastically increased in recent years and may confer an increased risk of malignancy. Records were obtained for IBD patients aged 18 or older who visited our institutional ED with a gastrointestinal chief complaint and who had a CT scan ordered by an ED physician. A predictive model for identifying a clinically actionable finding (CAF) on CT scan was created using logistic regression carried out on a predetermined set of variables. Data were available on 156 Crohn’s disease (CD) patients contributing 350 visits and 63 ulcerative colitis (UC) patients contributing 114 total visits. CAF was identified at 108/350 (30.9%) of visits in CD patients and 33/114 (29.0%) of visits in UC patients. History of CAF (OR 11.6, CI 4.54-29.6) and a platelet count above 400,000/mL (OR 3.42, CI 1.56-7.50) were the strongest predictors of CAF. History of psychiatric illness (OR 0.67, CI 0.35-1.29) and diarrhea (OR .043, CI 0.23-0.83) were associated with a lower likelihood of CAF. A prediction model was created that was able to detect 94.4% of CAF cases while correctly predicting CAF non-cases 35% of the time. This model holds promise as a tool to reduce imaging in this population.

Early Versus Late Immunomodulatory Therapy in Vogt-Koyanagi-Harada disease

Aug 2017 DOI 10.14302/issn.2470-0436.jos-17-1666

Purpose: To evaluate early versus late immunomodulatory therapy (IMT) for patients following initial diagnosis of Vogt-Koyanagi-Harada (VKH) disease. Methods: Retrospective review including all VKH patients seen 5/1/2014 to 4/1/2016 at LAC+USC. Early IMT was defined as starting an immunomodulatory agent within 3 months of corticosteroid initiation. Results: Twenty-seven patients were included, of whom 15 received early IMT and 8 received late IMT. Early IMT patients trended toward greater improvement in vision compared to late IMT (logMAR 0.59 vs. 0.11; p=0.14) with no differences in ocular complications including ocular hypertension (p=0.53) and cataract (p=1.0). Patients receiving early IMT averaged 0.93 recurrences versus 2.13 recurrences for late IMT (p=0.092). Of patients successfully taper off oral corticosteroids, the early IMT group was tapered in an average of 8.3 months versus 19.8 months for late IMT (p=0.0019). Conclusions: Early IMT in VKH may allow for shorter duration of corticosteroids with similar visual outcomes, ocular complications, and disease recurrences.

Morphological and Functional Abnormalities of the Thyroid Gland among End Stage Kidney Disease Patients

Aug 2017 DOI 10.14302/issn.2372-6601.jhor-17-1606

Several interactions exist between thyroid and kidney function in many disorders. Many publications explored the relationship between thyroid diseases (TD) and chronic kidney diseases (CKD). However, the morphological thyroid changes in patients with CKD or End Stage Kidney disease (ESKD) were not fully explored. The aim of this study is to explore the morphological and the functional abnormalities of the thyroid gland among ESKD patients as detected by Doppler ultrasound. Patients and Methods: All of the 92 ESKD patients at our center were consented and included in the study. Demographic and clinical data and biochemical and hormonal profiles were recorded. Every patient received a dedicated ultrasound scan of the thyroid gland. GE ultrasound system with Doppler capabilities and high frequency transducer was used. Grey scale imaging and Doppler ultrasound were used to image the thyroid gland for every patient. Taking the thyroid morphology detected by ultrasound and the thyroid function as the dependent variables, all other parameters of age, sex, BMI, occupation, residence, duration of time on dialysis and other comorbilities were taken as independent variables and their relationship to the dependent variables was further studied using appropriate statistical tests. Results: Thyroid nodule(s) presence was found to be the most prevalent thyroid morphology detected on ultrasound scanning. Fifty three patients (57.6%) were found to have ultrasound detected nodule(s). The nodule presence was correlated to different independent variables and was found to significantly correlate with age only. The thyroid function as reflected by the level of thyroid hormones was also studied for correlation with the independent variables. No correlation was found between the thyroid function and the presence of nodules. Conclusion and Recommendation: Ultrasound detected nodules are very common in ESKD patients. The presence of nodule significantly correlates with patient age denoting its degenerative nature. Ultrasound screening of the thyroid in ESKD patients may be cost effective. However, we recommend a larger multicenter study for better results.

A Role for in Vitro Disease Models in the Landscape of Preclinical Cardiotoxicity and Safety Testing

Jul 2017 DOI 10.14302/issn.2574-4372.jesr-17-1705

Drug-induced cardiotoxicity is one of the predominant reasons for drug attrition and withdrawals. This is of critical concern when potentially cardiotoxic drugs are administered to individuals with inherited arrhythmogenic cardiac diseases or with metabolic diseases such as obesity and diabetes, which are key risk factors for cardiovascular diseases. Pathophysiological alteration prevalent under such conditions can alter or exacerbate cardiotoxic responses. The growing incidence of obesity, diabetes and metabolic syndrome subject a significant percentage of the population to drug treatments, thereby augmenting their risk for drug-induced cardiovascular toxicity. Hence, screening for drug-induced cardiotoxicity early in the preclinical stages of drug development, by using appropriate human disease models, can be effective in ensuring safety in clinical trials and preventing late stage and post-marketing drug withdrawals owing to cardiotoxicity. The advent of human pluripotent stem cells (hPSC) and induced pluripotent stem cell (iPSC)-derived cardiomyocytes are revolutionizing safety/toxicity screening in human cells by providing relevant human-specific, renewable model systems to explore human drug toxicity. The ability to generate patient-specific iPSCs that can model cardiac diseases, now offers a valuable option that can further improve drug safety assessments and enable a more accurate prediction of toxicity that occurs in the representative population that are prescribed the drugs. Use of appropriate disease models will not only provide cost savings by decreasing potential drug attrition and withdrawals, seen with many drugs, but will also be a promising option to advance precision medicine

Increased Level of Lactate Dehydrogenase Correlates with Disease Growth in Algerian Children with Lymphoma

Jul 2017 DOI 10.14302/issn.2372-6601.jhor-17-1473

Objective: This study aimed to evaluate the relation of Lactate dehydrogenase (LDH) levels with stage of the disease and it role in monitoring tumor response to therapy in lymphoma patients. Methods. LDH levels were evaluated on 65 diagnosed Algerian children and compared to healthy control. Results: Our results revealed that LDH levels were significantly higher in untreated children with both hodgkin’s and non hodgkin’s lymphomas compared to control. Moreover, it was observed that the higher is the stage of disease, the more serum LDH level will be. However, there was a significant fall in serum LDH activity by completion of the chemotherapeutic courses. Conclusion: LDH plays an important role in tumor initiation and maintenance. The elevated serum LDH may reflect, release of the enzyme from malignant cells and suggest that they may reflect tumor burden and therefore correlate with disease progression.

MicroRNA: New Era for Therapeutic Strategy in Ischaemic Heart Disease

Jun 2017 DOI 10.14302/issn.2329-9487.jhc-17-1536

Over the last few decades, many research works highlighted the role of miRNAs on cardiac diseases. Ischaemic heart disease (IHD) or coronary heart disease is a condition that is mainly caused by atherosclerosis. It has been established that microribonucleic acids regulate many factors that are involved in the development and pathophysiology of IHD. As a result, there are great potential opportunities for miRNAs to be used as a biomarker for disease differentiation, as well as novel drug targets or therapeutics for the treatment and also as a diagnostic approach. As it is now evident that miRNAs play critical roles in the disease mechanisms, this review article tried to focus on the pathway, in which; the miRNAs stimulate the IHD to develop. By understanding the mechanisms, it will be possible to present a complete strategy of IHD treatment and also solving all the impediments that are highlighted in this article. Still, there are a number of limitations and obstacles on the way of developing a proper therapeutic approach that can be approved and well accepted. This review is mainly dependent on the potential of miRNAs as a promising arena on the field of cardiac treatment and the possible obstacles that are needed to be explored and overcome.

Single Daily Activity or Exercise Capacity Measurements Did not Predict Future Changes in Cardiovascular Risk Factors in Congenital Heart Disease

Jun 2017 DOI 10.14302/issn.2329-9487.jhc-17-1493

Objective: Studies suggest that cardiovascular risk of patients with congenital heart disease (CHD) is increased. This study aims on the predictive value of a single daily activity and exercise capacity assessments on the change of body-mass-index (BMI) and blood pressure in the future. Patients and Methods: We retrospectively analyzed all patients with CHD who underwent a daily activity assessment by triaxial accelerometry and accompanied cardiopulmonary exercise testing. From 276 patients 16 years or older (120 female, 28.6 ± 8.5 years) current BMI and blood pressure could be abstracted from their last outpatient visit. Results: After a mean follow-up of 5.5 ± 1.5 years, the BMI of the patients has increased from 23.0 ± 3.4 to 23.7 ± 3.5 kg/m2 (p<.001) corresponding to an annual increase of 0.14 ± 0.40 kg/m2 respectively. The systolic blood pressure decreased by -0.37 ± 3.14 mmHg (p=.049). The multivariable regression analysis corrected for confounders showed no association to annual BMI change according to baseline daily activity levels (p=.891) or peak oxygen uptake (p=.596). Only in patients with higher BMI at baseline (Beta= -.275; p<.001) and females (Beta= -.177; p=.009) increase in BMI was less. Also the blood pressure change was not associated with daily activity levels (p=.420) and peak oxygen uptake (p=.732) at baseline. Conclusions: Single daily activity or exercise capacity measures do not predict future BMI or blood pressure changes. Regular evaluation of functional status including exercise testing, activity assessment and tailored counseling are therefore recommended in patients with CHD.

Rescuing Canavan Disease by Redirecting Metabolic Processing: Support for the Astrocyte Hypothesis of Canavan Disease Generation and A Possible Human Cure

Apr 2017 DOI 10.14302/issn.2572-5424.jgm-17-1482

Canavan disease (CD) is a globally occurring but rare human spongiform leukodystrophy that is associated with inborn errors affecting the activity of aspartoacylase (ASPA), an enzyme highly expressed in oligodendrocytes that hydrolyzes N-acetylaspartate (NAA). Lack of ASPA activity is associated with the inability of oligodendrocytes to build or maintain axon-enveloping myelin sheaths. The primary source of NAA in brain is neurons, cells that synthesize but cannot catabolize it. Neurons also synthesize N-acetylaspartylglutamate (NAAG) from NAA and glutamate but cannot catabolize this substance as well. For their metabolism, these substances are released to extracellular fluid and are metabolized by oligodendrocyte ASPA and astrocyte NAAG peptidase respectively. A hypothesis developed suggested that the cause of the leukodystrophy component in CD was due to release of NAAG by neurons at white matter nodes of Ranvier, its catabolism by astrocytes forming NAA and increased osmotic-hydrostatic pressure as a result of its buildup at these nodes due to the lack of ASPA activity. In this communication, we provide evidence supporting this hypothesis and comment on the cause and possible cure for human CD.

Differentiating Depression from Apathy in Chronic Kidney Disease: A Prospective Study

Mar 2017 DOI 10.14302/issn.2476-1710.jdt-16-1262

Background. Emotional deterioration is frequently found in patients with chronic kidney disease, but some patients are affected by depressed mood without fulfilling the criteria of a depressive disorder. Those patients might rather suffer from an apathy symptom. Apathy as a symptom of a medical disease is accompanied by loss of motivation and interest, cognitive impairments, and emotional distress. Our study tested how groups of apathetic and depressed chronic kidney disease patients responded to a single haemodialysis session on measures of mood. Methods. 21 haemodialysis patients were assigned to subgroups (depressed, apathetic only, without depression and apathy) according to clinical relevant cut-offs. Sensitive questionnaires were administered to monitor mood state in general and mood changes before and after a single haemodialysis session in the chronic kidney disease patients. The results were compared to 20 age-matched healthy controls receiving no treatment. Results. Fortheen dialysis patients had eighter apathy or depressen and seven had neighter apathy nor depression. Mood state was seriously affected in all haemodialysis patients with depressed patients showing the largest effect compared to healthy controls. Patients with apathy and patients without apathy and depression were comparable in their mood state. We observed a positive mood change after the haemodialysis only in patients without apathy and depression. Their mood state improved significantly and reached nearly the level of healthy controls. Conclusions. The absence of a short-term mood change in apathetic dialysis patients makes them comparable to dialysis patients with depression. We argue that apathetic patients lack the probable mood brightening effect of the haemodialysis. The lack of emotional improvement by dialysis sessions could also lead to decreased adherence of the patients. Hence, apathy seems to be a serious symptom in chronic kidney disease that is worth to be considered at least in the diagnostic process. Accompanying psychotherapeutic care for these patients would be desirable

Bioinformatic Analysis of Coronary Disease Associated SNPs and Genes to Identify Proteins Potentially Involved in the Pathogenesis of Atherosclerosis

Mar 2017 DOI 10.14302/issn.2326-0793.jpgr-17-1447

Factors that contribute to the onset of atherosclerosis may be elucidated by bioinformatic techniques applied to multiple sources of genomic and proteomic data. The results of genome wide association studies, such as the CardioGramPlusC4D study, expression data, such as that available from expression quantitative trait loci (eQTL) databases, along with protein interaction and pathway data available in Ingenuity Pathway Analysis (IPA), constitute a substantial set of data amenable to bioinformatics analysis. This study used bioinformatic analyses of recent genome wide association data to identify a seed set of genes likely associated with atherosclerosis. The set was expanded to include protein interaction candidates to create a network of proteins possibly influencing the onset and progression of atherosclerosis. Local average connectivity (LAC), eigenvector centrality, and betweenness metrics were calculated for the interaction network to identify top gene and protein candidates for a better understanding of the atherosclerotic disease process. The top ranking genes included some known to be involved with cardiovascular disease (APOA1, APOA5, APOB, APOC1, APOC2, APOE, CDKN1A, CXCL12, SCARB1, SMARCA4 and TERT), and others that are less obvious and require further investigation (TP53, MYC, PPARG, YWHAQ, RB1, AR, ESR1, EGFR, UBC and YWHAZ). Collectively these data help define a more focused set of genes that likely play a pivotal role in the pathogenesis of atherosclerosis and are therefore natural targets for novel therapeutic interventions.

Evaluation of Vitamin D Deficiency in Patients with Chronic Liver Disease and Its Clinical Significance

Dec 2016 DOI 10.14302/issn.2379-7835.ijn-16-1381

Introduction: Vitamin D deficiency has been reported highly prevalent in Chronic liver disease (CLD) and there is an emerging interest to explore the relationship of vitamin D deficiency and severity of various types of CLD. Aim: To evaluate vitamin D level in patients with various type of CLD and clinical significance of its deficiency. Materials and Methods: Serum vitamin D levels were measured by ELFA in 100 patients (91 male and 9 female) suffering from CLD. The degree of liver dysfunction was estimated by Child Pugh criteria and Model for End stage Liver Disease (MELD) score. Results: Prevalence of vitamin D deficiency and insufficiency were 43% and 42% respectively among CLD patients. Low levels of vitamin D were associated with leucopenia or leucocytosis indicating increased risk of infection. On Linear regression vitamin D level showed significant negative correlation with Child Pugh score (r = – 0.7382, p<0.0001) and MELD score (r = – 0.6673, p<0.0001). Our study shows low vitamin D level was associated with poor outcome (mean vitamin D level 10.38 ± 2.35 who died vs 23.14 ± 6.68 who survived and discharged). Conclusion: CLD is associated with a significantly low level of vitamin D which was independent to patient’s gender, BMI, residence and education level. The lower level of vitamin D is associated with severity of CLD, mortality and increased risk for infections. Awareness of serum vitamin D level in patients with CLD is important to improve outcome.

Prevalence of Impulse Control Disorders among Adult Filipino Patients with Idiopathic Parkinson’s Disease seen at Jose R. Reyes Memorial Medical Center

Oct 2016 DOI 10.14302/issn.2470-5020.jnrt-16-1240

Background: Impulse Control Disorders (ICDs) are characterized as pathologicalbehavioral patterns of excess impulsivity which may result as part of the non-motor complications of Parkinson’s disease (PD). These significantly affect the patient’s overall quality of life and have impact on their care givers, as well. Currently, the prevalence of ICDs among adult Filipino patients with Parkinson’s disease is unknown and less reported. Objectives: The study is intended to determine the prevalence of ICDs and its severityamong adult Filipino patients with idiopathic Parkinson’s disease seen at Jose R. Reyes Memorial Medical Center. Specifically, this study will identify risk factors and the clinical correlates to these patients. Methods: Adult Filipino patients diagnosed withidiopathic Parkinson’s diseasewhowere seen at the outpatient department from March 2015 – September 2015 are screened for the study. The Modified Hoehn and Yahr staging was utilized to determine the stage of PD. With approval from the author, the Questionnaire for Impulsive-Compulsive Disorders in Parkinson’s Disease-Rating Scale (QUIP-RS) was used for detecting the presence of ICDs and corresponding severity. Results: We were able to examine 66 patients (31 males and 35 females) withidiopathic Parkinson disease. Majority of the patients manifested with Tremor Dominant (50%) subtype, followed by Early Disease Onset (34.8%), and Non-Tremor Dominant (15.2%). Sixteen (16) out of 66 patients (24.2%) have ICD symptoms with the following incidence rates: hobbyism/ punding 56.25%, compulsive eating 50%, hypersexuality 18.75%, compulsive shopping 18.75, Dopamine dysregulation syndrome 18.75%, and gambling 12.5%. Overall average QUIP-RS score is 5.42. There is significant association of PD duration with occurrence of ICD symptoms; the longer the PD duration, the higher risk of having ICD symptoms (x2 20.41; p = 0.026). Patients with higher mean modified Hoehn and Yahr stage (2.66±0.94), t 2.735, df 64, p 0.008, have much higher incidence of ICD symptoms. Conclusion: Filipino patients with idiopathic Parkinson disease who are majority onlevodopa + carbidopa therapy may develop impluse control disorders (ICDs). Other contributory factors in development of ICDs include longer duration of PD and higher mean Modified Hoehn and Yahr stage.

Distinguishing between Knowledge Gaps and Misconceptions of Alzheimer’s Disease among Caregivers in the UK

Oct 2016 DOI 10.14302/issn.2474-7785.jarh-16-1128

A popular scale for assessing knowledge about Alzheimer’s disease is the Alzheimer’s Disease Knowledge Scale (ADKS). The aim of the study was to investigate the effect of adding ‘don’t know’ to the original ‘true’ or ‘false’ response option. It was assumed that this modification would provide insight into the reasons underlying incorrect responses and could distinguish between misconceptions and knowledge gaps. To investigate this, carers (care home carers and informal carers) and members of the general population were recruited. The results showed that percentage correct responses was lower than previously reported, suggesting potential inflation of knowledge by guesses without the ‘don’t know’ option. Moreover, care-home workers were more likely to select the incorrect response than ‘don’t know’ compared to informal carers for several items related to the earlier stages of AD, suggesting a higher level of misconceptions around this topic and highlighting potential training needs for care home carers.

Psychological “Risks” of Colonoscopy are Greater Amongst Fecal Immunohistochemical Test Positive Individuals than those with Inflammatory Bowel Disease

Aug 2016 DOI 10.14302/issn.2471-7061.jcrc-14-426

Background: Colorectal cancer (CRC) screening by Fecal Immunohistochemical Testing (FIT) followed by colonoscopy reduces colorectal cancer mortality. Barriers to colonoscopy should be minimised. Objective: To compare psychological “risks” of colonoscopy in FIT positive (FIT+) subjects and those with Inflammatory Bowel Disease (IBD). Method: IBD patients undergoing colonoscopic CRC surveillance were age and gender matched with FIT+ individuals awaiting colonoscopy. Subjects completed Spielberger State and Trait Scales for current levels of anxiety, depression, anger and curiosity, versus long term personality tendencies. Results: 70 IBD respondents were matched with 70 FIT+ respondents, (57% male, mean age 57.6 years). FIT+ subjects demonstrated greater scores for state Anxiety (22.3 vs 20.3 p=0.024), Curiosity (24.3 vs 21.8 p=0.036), Anger (13.7 vs11.5 p=0.037) and Depression (23.8 vs21.2 p=0.002). Conclusion: FIT+ patients experience more anxiety and depression prior to their colonoscopy than IBD patients, which may reduce colonoscopy uptake and is important to address.

Muscle Activation Signals During Gait Parkinson’s Disease are More Rhythmic than in Healthy Controls

Aug 2016 DOI 10.14302/issn.2470-5020.jnrt-15-750

Background To quantify the underlying rhythmic patterns observed in surface electromyography (SEMG) in patients with Parkinson’s Disease (PD), to compare rhythmicity of PD gait with normal gait, and to compare overground walking to treadmill gait. Methods Eight individuals with idiopathic PD, and ten individuals with no history of neurological disorders participated. SEMG was recorded from the vastus lateralis, tibialis anterior, lateral gastrocnemius and biceps femoris muscles bilaterally. Each participant performed two trials of overground walking and two trials of treadmill walking at a self-selected comfortable walking speed. SEMG was analyzed using a non-linear statistical model that identified underlying recurrent locomotor patterns, which estimated the relative contribution of central pattern generators to the observed muscle activation signals. An index of rhythmicity was determined from the statistic, R2. Results The rhythmicity of PD gait was significantly higher than that of normal gait (p = .0458). There was also a significant difference between the rhythmicity of overground walking and treadmill walking (p = .0097). Conclusions Individuals with PD appear to walk with muscle activation patterns that are more rhythmic than normal. This suggests that there is more stride-to-stride consistency, and there are fewer postural adjustments and responses to perturbations. We also found that treadmill gait was more rhythmic than overground walking. These findings, although preliminary, challenge the paradigm and current approach to gait retraining of patients with PD.

Organic or Psychiatric Disease? A Misdiagnosed Superior Mesenteric Artery Syndrome

Aug 2016 DOI 10.14302/issn.2379-7835.ijn-16-1154

Superior mesenteric artery syndrome 1234 is a rare disorder characterised by a compression of the duodenum because of the reduced angle between the aorta and superior mesenteric artery. The disease is clinically characterised by abdominal pain, lack of appetite, vomiting and anorexia; some of these symptoms also characterise eating disorders. We report a case of a young female patient presenting with abdominal pain, loss of appetite and chronic loss of weight which led to misdiagnosis of anorexia nervosa; ultrasound with echo color Doppler methodology has subsequently allowed the correct diagnosis.

Metabolic Acidosis and Cardiovascular Disease in Patients on Peritoneal Dialysis

Jun 2016 DOI 10.14302/issn.2329-9487.jhc-15-905

Backgroud: Metabolic acidosis, a common condition particularly in end stage renal disease patients, results in malnutrition and inflammation. In this study, we focused on the importance of metabolic acidosis on manifestations of cardiovascular disease in patients on peritoneal dialysis. Methods: We studied 20 patients on continuous ambulatory peritoneal dialysis (CAPD), 15 males and 5 females, on mean age 61.6 ±11.3 years old. Metabolic acidosis was determined by serum bicarbonate concentrations less than 22mmol/L, which were measured in gas machine. Dialysis adequacy was defined by total Kt/V/week for urea including peritoneal Kt/V for urea and residual GFR (ml/min/1.73m2). High sensitivity C-reactive protein (hsCRP) was measured using enzyme linked immunoabsorbed assay (ΕLISA). The concentrations of intact-parathormone (i-PTH) and beta2-microglobulin (beta2M) were measured by radioimmunoassays. Arterial stiffness was measured as carotid-femoral pulse wave velocity (c-f PWV) and augmentation index (AIx). We built a Cox regression analysis to predict coronary artery disease (CAD), congestive heart failure (CHF) and peripheral vascular disease (PVD). Results: Serum bicarbonate levels were inversely associated to beta2M, i-PTH and AIx (r=-0.451, p=0.04, r=-0.477, p=0.03 and r=-0.569, p=0.009 respectively). Cox- regression analysis revealed significant association of serum bicarbonate levels and PVD having as confounders traditional and specific for these patients risk factors. Conclusion: Metabolic acidosis may be an independent risk factor for arterial stiffening and peripheral vascular disease manifestation in patients on peritoneal dialysis.
