Lower limb osteoarthritis, a widespread age related chronic condition is often accompanied by an increased tendency to fall and thereby various degrees of intrinsic and extrinsic injury. Falls, in turn may provoke the disease alone and in turn a high falls risk and cycle of recurrent falls and heightened disability. This report which updates what is known about falls in the context of disabling osteoarthritis argues for a possible future ecological orientation rather than a focal uni dimensional approach to addressing this costly health problem. It examines osteoarthritis falls risk factors, falls injury prevention attempts, and recommendations to advance research and practice using an ecological analytic approach in this regard. Using the PUBMED data base and others, lower limb osteoarthritis linkages and falls interaction studies were sought and examined. The data revealed osteoarthritis can lead to the chances of incurring one or more falls and further health and disability challenges, while falling can provoke the onset of osteoarthritis in its own right. Although many factors appear to be involved, these are rarely viewed through a broad multi dimensional ecological perspective, thus are confusing or overwhelming to apply to the active community dwelling elderly subject.

Several mRNA vaccines are used on the population in the U.S. I started predicting the dangers of mRNA vaccines before March 2021 and update my findings periodically. My prior model study enabled me to identify many flaws in clinical trials, side-effect evaluation methods and mechanism studies, and I also considered consistent failure in predicting drug side effects in the past and systematic failure of FDA in keeping out dangerous drugs from market. I found that the risks of vaccination cannot be determined by experiments alone and must be determined by using a combination of methods. By studying mRNA expression dynamics and kinetics, I predict that vaccination with mRNA vaccines may increase cancer risks, multiple organ failure risks, earlier death risks, genome alteration speeds by one or more mechanisms, alter the normal selection process for viral evolution resulting in more virulent viruses, and aggravate chronic diseases or cause healed diseases to relapse. Two root problems are practical inability to control expression sites and severe adverse reactions from repeated vaccination. Based on mRNA bio-distribution, the mRNA mainly strikes the liver and other vital organs, and poses grave dangers to persons whose vascular functional reserves are relatively small, or whose vascular systems are temporarily burdened by other causes such as viral infections or life activities. If an mRNA vaccine is administered on a pregnant woman by second or booster shots, spike protein synthesis in fetus brain disrupts the highly regulated protein synthesis processes, resulting in potential brain damages. In less than a year, most of my early predicted damages are being materialized or are on the track to hit the population. In this update, I present a benefits-and-risks map to show how the number of deaths caused by mRNA vaccines is grossly underestimated and why claimed benefits like 95% effectiveness rate and 90% death rate reduction are meaningless and misleading.

Aflatoxins (AFs)B1, B2, G1, and G2 are important hepatotoxic mycotoxins produced by Aspergillus flavus, A. parasiticus, and A. nominus. They are converted into metabolites of AFM1, AFM2, B2a, and aflatoxicol by cytochrome P450-related enzymes in the liver after digestion of the feed. These metabolites accumulating in the animal-derived food products such as eggs, milk, cheese, and honey cannot be destroyed by pasteurization or heating process and may influence public health negatively. Therefore, it is very important to prevent or limit the aflatoxin contamination in the animal feeds to decrease the risk of contamination of these metabolites in animal-derived foods.

Pharmacodynamic modeling of sunscreens was performed using a new concept of Skin UV Index (SUI) on the exposed skin as a parameter to evaluate the potential effectiveness of sunscreens against sun damage. The SUI predicts the UV heat intensity on the skin surface in terms of the solar UV Index at the time of the study and is calculated by solar UV Index/sunscreen’s SPF. SUI numbers for sunscreen with SPF ranging from 2 to 100 under a solar UV Index of 10 was used for illustration. Based on guidelines from WHO, Australia and New Zealand, sunscreens yielding SUI < 3 are assumed to be effective against sun damage such as sunburn and melanoma. Based on the above assumption, sunscreens with SPF > 4 were found to be effective when sunscreens were evenly applied at 2 mg/cm2. Review of numerous studies suggests that missing applications may represent a major, seemingly unavoidable, SPF-independent factor causing unintended sunburns for sunbathers in the US and other countries with a temperate climate. This might in turn become a major factor for causing exponential increase in melanoma incidence rates observed in the last few decades. For example, in an SPF 30 sunscreen study all 25 participants suffered unintended sunburns after one week of sunbathing. Also, a mean missing application of 20% of the total exposed area and a mean missing of about 50% of the time were reported in two separate studies. Simulations were also performed with under-applications of 50% and 75%. The present simulations may provide a rationale of why routine use of a low SPF 8 sunscreen was reported to be effective against melanoma in a 2018 Australian study. Based on model simulations it is proposed that in the US, SPF 8 sunscreen and SPF 2 to 6 sunscreen may be adequate for routine, unintentional use for sun-sensitive populations and non-sun-sensitive populations, respectively.

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.

Background Acute diarrhea is the major cause of health public problem among paediatric patients in Tanzania. And in Low income countries (LICs), studies have shown, Acute watery Diarrhea (AWD) is the cause of morbidity and mortality which can be prevented by immediate identification and treatment of complications. Methods A prospective cohort study was done between December 2021 and April 2022 to determine the risks, complications, management strategies and predictors of mortality among paediatric patients ≤12 years of age with severe diarrhea. We excluded those who arrived in cardiac arrest at the Emergency Medicine Department (EMD) of Muhimbili National Hospital (MNH). Proportion was used to summarize the counts and frequency of participants who were at risk of complications and management strategies given and for predictors of outcomes. A Modified Poisson log linear model with a robust estimation test was used to test for significant associations between predictors and outcomes. Multivariate logistic regression was used to adjust for confounders. Results A total 6,570 paediatric patients presented to EMD during study period, and we recruited 144 (2.2%). The median age was 1 (IQR 0.7-2.0) years and most were male 86 (59.7%). Among the study participants with diarrhea, 120 (83.3%) had dehydration, acidosis 60 (42.3%), hypoglycemia 8 (5.6%), hypokalemia 76 (53.1%), and Acute renal failure 11 (7.6%). Those patients with complications received appropriate management, including IV crystalloid solution given to 131 (90.97%), and correction of acidosis 60 (42.3%), hypoglycemia correction with IV dextrose 10% 6 (4.2%), and hypokalemia and infections were corrected with IV potassium chloride 52 (36.1%) and IV antibiotic treatment 84 (58.3%) respectively. Conclusion Pediatric patients under 2 years of age are at high risk of severe diarrhea with dehydration as compared to other ages. Early referral and availability of point care tests are essential in early recognition of accompanied complications.

Background/Aim Sleep disturbances are common and are associated with impaired daytime functioning, reduced quality of life, and increased health risks. Non-pharmacological neuromodulatory interventions have gained interest as alternatives to hypnotic medication. Pulsed electromagnetic field (PEMF) therapy has been proposed as a non-invasive approach to improve sleep quality and recovery, but evidence from large, well-controlled trials remains limited. The objective of this study was to evaluate the efficacy and safety of pulsed magnetic field therapy (PMT) on sleep quality, sleep-related symptoms, daytime functioning, and well-being in adults with heterogeneous sleep complaints. Materials and Methods In this remote, randomized, double-blind, placebo-controlled trial, 217 adults reporting non-restorative sleep, difficulties initiating sleep, or frequent nocturnal awakenings were assigned to active PMT using a PEMF device (Night Harmony Female/Male protocol) or a sham application for three weeks. Primary outcomes were changes in the Pittsburgh Sleep Quality Index (PSQI) global score and self-rated sleep satisfaction, restfulness, and sleep initiation difficulties. Secondary outcomes included sleep diary measures, daytime functioning, well-being (WHO-5), symptom burden (MYMOP), and daytime sleepiness (Epworth Sleepiness Scale). Analyses followed the intention-to-treat principle using ANCOVA with baseline values of the respective parameter as covariate. Results Both groups showed significant improvements over time in global sleep quality and most secondary outcomes (p < 0.001). Between-group differences in PSQI global score were not significant (p = 0.314). However, active PMT resulted in significantly greater improvements in subjective sleep satisfaction (p = 0.02) and restfulness (p = 0.02), particularly among participants with moderate to severe baseline sleep disturbances (p < 0.001 for both). Sleep continuity measures improved similarly in both groups. No serious adverse events were reported. Conclusions PMT produced modest but significant improvements in subjective restorative aspects of sleep beyond placebo effects and was well tolerated. Further studies using objective sleep measures and longer follow-up are warranted.

Background Domestic violence among HIV discordant couples poses significant public health challenges, affecting treatment adherence and HIV transmission risks. This study examined factors contributing to domestic violence among HIV discordant couples in Kicukiro District, Rwanda. Methods A cross-sectional study was conducted among 384 HIV discordant couples from eleven health centers using stratified systematic sampling. Data were collected through structured face-to-face interviews and analyzed using descriptive statistics and bivariate analysis. Results Domestic violence prevalence was 41.1% physical violence, 34.2% sexual coercion, and 52.3% emotional abuse. Key socio-demographic risk factors included female gender (56% vs. 29% males, p<0.001), older age (61% in ≥55 years vs. 32% in 18-24 years, p=0.004), unemployment (55% vs. 34% formal employment, p=0.014), and financial hardship (63% vs. 25% comfortable situations, p=0.002). Behavioral factors included alcohol use (58% vs. 38%, p=0.021), substance abuse (62% vs. 35%, p<0.001), and poor conflict resolution (72% vs. 25%, p<0.001). Contextual factors like hostile HIV disclosure reactions (68% vs. 34%, p<0.001) and HIV-related stigma (60% vs. 35%, p<0.001) significantly increased violence risk. Conclusions Domestic violence among HIV discordant couples is multifactorial, driven by socio-economic, behavioral, and HIV-related factors. Integrated interventions addressing economic empowerment, conflict resolution skills, stigma reduction, and couple-centered counseling are urgently needed.

Background Malnutrition is a significant public health issue in Bangladesh, particularly impacting women and children. Rajshahi, marked by socio-economic disparities, offers a distinctive context to explore the nutritional status and health outcomes of these vulnerable groups. Objectives This study aims to assess the nutritional status of women and children in Rajshahi and investigate associated health outcomes. Additionally, it seeks to identify socio-economic and cultural factors that influence nutrition. Methods A mixed-methods approach was utilized, incorporating a cross-sectional survey of 460 households and in-depth interviews with mothers and caregivers. Anthropometric measurements were taken to evaluate the nutritional status of women and children, while dietary assessments measured nutrient intake and diversity. Logistic regression analysis was performed to determine the likelihood of malnutrition based on socio-economic characteristics, thereby identifying key risk factors. Results The findings indicate a troubling prevalence of malnutrition, with 36% of children under five classified as stunted and 25% as underweight. The analysis highlights critical factors contributing to chronic undernutrition, including maternal education, employment, and dietary diversity. Notably, mothers aged 27-37 exhibit a lower risk of undernutrition, and urban households with secure food access demonstrate better nutritional outcomes. Discussion Maternal education and employment were positively associated with better nutritional outcomes, as educated and employed mothers had higher chances of maintaining a normal BMI. Regular ANC visits (≥4 visits) were crucial for improved maternal nutrition. Household food security emerged as a significant determinant, with food-secure households showing better maternal nutritional status. Safe water access and adequate dietary diversity were also linked to improved maternal BMI. Additionally, factors such as child birth weight, exclusive breastfeeding, and childhood diarrhea significantly influenced maternal nutrition. Moreover, frequent antenatal care visits and a diverse diet are vital in mitigating undernutrition risks among children. Conclusion This study emphasizes the urgent need for targeted interventions to combat malnutrition in Rajshahi. Recommendations include implementing community-based nutrition education programs and improving access to healthcare services. By addressing the socio-economic and cultural determinants of nutrition, stakeholders can enhance health outcomes for women and children in the region, ultimately contributing to broader public health objectives in Bangladesh.

Rwanda is a small Central African country. A land with thousands of hills and mountains. It is a low-income country and one of Africa's fastest-growing economies. It is home to a variety of ecosystems, such as mountainous rainforests, gallery forests, savanna woodlands, wetlands, aquatic forests, and agroecosystems. From rising temperatures to changing rainfall patterns, the hidden dangers of climate change are unmasking themselves in the form of various health risks. Every year, many deaths, bodily injuries, and house collapses, among other repercussions, are documented as detrimental effects of climate change events on public health. This article delves into the intricate relationship between climate change and public health in Rwanda, exploring the adverse effects it has on vulnerable communities. By shedding light on this pressing issue, we can better understand the urgency of taking action to mitigate the impact of climate change on public health as well as potential solutions to the current predicament. The authors researched several literatures to develop their perspectives on the subject and explored potential solutions to protect the well-being of Rwandans in the face of this global crisis.

Background and Purpose Public health problems are caused by the emergence of environmental pollution and infectious diseases, which have caused concern around the world. The public health threat affects the relationship between people. Population growth and associated pressures increase difficulties associated with effective means of maintaining public health. The diseases transmitted from human and livestock communication, water pollution, air pollution, and environmental pollutants urge us to find new solutions to address these problems. Understanding the environmental and environmental health is a prerequisite for protecting public health. In Iran, like other countries in the world, the issue of environmental protection and its compliance with the first program of economic, social and cultural development of the Islamic Republic has begun and expanded in the future. In this regard, new perspectives are being introduced that will bring about dramatic changes at various levels of planning, processes and specialized sectors such as civil, industrial and educational sectors. The training of engineers in this regard can play a very important role in refining the attitudes of young engineers and using these bases in their specialized activities. One of the important tasks of universities is to provide a suitable platform for such training. In this regard, it is essential that the major industrial universities of the country develop various programs in this field. Materials and Methods The present study is a review of the type of validity that is performed through search of authoritative scientific databases such as PubMed and Scopus, Google scholar, PubMed using the key words of building safety and health, HSE, and prevention methods are the latest information. Results Implementing the principles of HSE in various construction, industrial and other projects requires time, because any change that is considered in the system requires a change of attitude, which in turn requires time to adapt and adapt to the new conditions. The conditions for the projects in this research are their current conditions, and the next research, after a while, can determine the percentage of project progress in terms of HSE. Conclusion In order to comply with the principle of HSE cases, there is a need for training. These trainings should be executed at different levels and levels of contracting and monitoring so that the level of awareness of the risks involved in the development of civil operations between the personnel reaches a common frontier.

The work environment, in its most general conception, alludes to biased expectations of risks and benefits around a function and in relation to the performance of a working group, but in its factorial structure, dimensions have been found that explain a moderate percentage of the variance of the construct. In this sense, the objective of this paper is to specify a model for the study of the work climate, considering the institutionalism and human capital of a public university. An exploratory study was carried out with an intentional sample of 125 administrative personnel. From a structural model it was found that the relationship climate factor explained the highest percentage of the variance (21%) and it was the reflective dimension of the construct (0.524). The inclusion of the task climate is recommended due to its link with the leadership and the collaborative climate.

Underwater sound is very important to most fishes and invertebrates. Underwater sounds from both natural and human sources can have adverse effects upon aquatic animals, and especially fishes, and invertebrates. It is important to examine the effects of sound upon them, and especially the effects of sounds derived from human sources (anthropogenic sounds). It may be possible to introduce protective regulations to reduce their effects. Fishes and invertebrates can detect underwater sounds, and they use sound to obtain key information about the environment around them. They can also make sounds themselves, especially during their spawning. Sounds travel rapidly over great distances in water and can provide detailed information to these animals on the presence of prey, predators, and related species, while the overall acoustic scene provides them with key information about their environment. Anthropogenic sounds can be very harmful, and it is therefore important to deal with them. A succession of reports and scientific papers have emphasised the risks to these animals from exposure to man-made sounds or noise and will be mentioned in this paper, which also deals with the Criteria and Metrics for assessing the effects of underwater sound on fishes and invertebrates.

Background Osteoarthritis, the most common joint disease and one affecting a large number of older adults is not always amenable to the use of passive interventions such as surgery or pharmacologic interventions, but even then, to maximize any desirable intervention approaches, a trustworthy and supportive partnership with the sufferer is strongly indicated. Complicating this process are emerging equity and persistent health literacy issues, as well as post COVID-19 service associated ramifications and persistent disease risks. Aim This mini review was designed to examine what current data reveal as regards the presentation of osteoarthritis and its pathology among the older adult as of the current post COVID-19 pandemic period in 2022, and how health literacy and equity issues are likely implicated in some degree with the disease presentation and its outcomes and will be likely to continue, unless remediated. Methods Peer reviewed published articles on this topic were sought from multiple data bases using the key words- osteoarthritis, health equity, health literacy, prevention, and intervention. Results As in prior years, osteoarthritis continues to induce considerable physical disability and consistently impedes the attainment of a high life quality for many older adults. Although not studied to any degree, attention to health equity and literacy issues appear to pose additional osteoarthritis intervention challenges, especially among the long COVID affected older adults and those with low income and educational levels. Conclusions Many behaviourally oriented and necessary osteoarthritis management approaches and interventions may fail to reduce the functional disability and pain experienced by older people with any form of osteoarthritis to any meaningful degree if a) the provider does not tailor their recommendations in light of possible prevailing health literacy, economic, and educational challenges; b) the patient does not understand how their health behaviours impact joint disease as well as COVID-19 risk status, and are not empowered to undertake these.

Studies have linked freshwater snails with human flukes as a result of repeated contacts with contaminated water. This study is aimed to determine the distribution of freshwater snails and their infectivity rates along human dwellings in Okigwe Imo state using Physico-Chemical parameters. Freshwater snails were collected by using long plastic spoons and with hand-picking method. The Physico-Chemical parameters were determined with appropriate instrument and freshwater snails harvested from the site were morphologically identified. One thousand four hundred and nine (1409) freshwater snails belonging to the species Lymneae and Bulinus were collected once a week throughout the period of study with the relative percentage of 43.9%; 29.9% ;26.2% respectively. The infectivity rate was highest in snails that were collected in the month of May compared to those collected in June and July, the rate was 69.2%, 50.1% and 33.6% in the months of May, June and July respectively. Dissolved oxygen (DO), Biological oxygen demand (BOD) and PH were found to significantly influence snail distribution in the site (p<0.05). The finding showed that 54.2% of all the snails collected were infected. The snail distribution observed may give an insight into some aspects of the epidemiology of trematodes infection in Okigwe the site for the study and their potential risks to infect human beings and animals.

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

With the spread of the new coronavirus around the world, governments of various countries have begun to use the mathematical modeling method to construct some virus transmission models assessing the risks of spatial spread of the new coronavirus COVID-19, while carrying out epidemic prevention work, and then calculate the inflection point for better prevention and control of epidemic transmission. This work analyzes the spread of the new coronavirus in China, Italy, Germany, Spain, and France, and explores the quantitative relationship between the growth rate of the number of new coronavirus infections and time. In investigating the dynamics of a disease such as COVID-19, its mathematical representation can be constructed at many levels of details, guided by the questions the model tries to help answer. Mathematical sophistication may have to yield to a more pragmatic approach closer to the ability to make predictions that inform public health policies. Background In December 2019 , the first Chinese patients with pneumonia of unknown cause is China admitted to hospital in Wuhan, Hubei Jinyintan , since then, COVID-19 in the rapid expansion of China Wuhan, Hubei, in a few months time, COVID-19 is Soon it spread to a total of 34 provincial-level administrative regions in China and neighboring countries, and Hubei Province immediately became the hardest hit by the new coronavirus. In an emergency situation, we strive to establish an accurate infectious disease retardation growth model to predict the development and propagation of COVID-19, and on this basis, make some short-term effective predictions. The construction of this model has Relevant departments are helpful for the prevention and monitoring of the new coronavirus, and also strive for more time for the clinical trials of Chinese researchers and the research on vaccines against the virus to eliminate the new corona virus as soon as possible. Methods According to the original data change law, Establish a Logistic growth model, we collect and compare and integrate the spread of COVID-19 in China, Italy, France, Spain and Germany, record the virus transmission trend among people in each country and the protest measures of relevant government departments. Findings Based on the analysis results of the Logistic model model, the Logistic model has a good fitting effect on the actual cumulative number of confirmed cases, which can bring a better effect to the prediction of the epidemic situation and the prevention and control of the epidemic situation. Interpretation In the early stage of the epidemic, due to inadequate anti-epidemic measures in various countries, the epidemic situation in various countries spread rapidly. However, with the gradual understanding of COVI D -19, the epidemic situation began to be gradually controlled, thereby retarding growth

Open bite malocclusion, due to it’s multifactorial etiology, has always been considered a difficult problem to treat. Often associated with transverse maxillary deficiency, this is a real challenge in the field of orthodontics. The traditional approach, for this type of anomaly, in adult patients, is orthognathic surgery and RME (rapid maxillary expansion). There are several approaches to the treatment of adult patients using digital technology. Mini-implant supported palatal expander limits the side effects of the conventional RME and is less invasive compared to orthognathic surgery. Precise and predictable mini-implant insertion, using a customized surgical guide, provides a safe therapeutic approach. This case report combines Cone-beam computed tomography (CBCT), laser scan superimposition, computer-aided design (CAD) and 3D printing in order to design and print a customized surgical guide for orthodontic mini-implant insertion. A CBCT scan was performed to determine the optimal site for mini-implants’ placement. Using the 3Shape Trios Intraoral Scanner the maxilla and the mandible were laser-scanned. Blue Sky Plan 4 software was used to design the surgical guide, and RayWare software was used for printing it. 4 mini-implants were inserted using a safe and predictable technique. The 3D technology represents the future of orthodontics, reducing the risks, chair-side time while providing the best treatment plan for the patient.

COVID-19 remains a global public health emergency till date. It is eminent that the transmission of the disease is subjective to people’s readiness to implement public health preventative strategies and these are often related to knowledge. Proper public knowledge about COVID-19 plus its predisposing factors is critical to effectively manage the increasing public health risks. However, socio-demographics have been implicated to COVID-19 infection risk and management outcome. Thus, this present study examined the influence of knowledge on COVID-19 risk outcome, the contribution of socio-demographics on the risk of COVID-19 and predicted synergistic effects of knowledge and socio-demographics on the risk of COVID-19. All measured was strictly perception amongst African sampled with an online Google form as the primary data source. The Correlation designed used Zr Statistics of Fisher Transformation to determine the differences between the two correlation coefficients of the prediction variables after an initial test using Pearson Product Moment Correlation between COVID-19 risk and Knowledge plus socio-demographic. The hypothesis was tested using Statistical Package for Social Science version 21 and iStat at varying significant levels of 0.05 and 0.01 respectively. Generally, a significant relationship exists between COVID-19 risk and knowledge level but not with composite socio-demographics. However, specific significant relationship (p<0.05) was noticed between COVID-19 risk and age (r=0.220) as well as marital status (r=-0.158). Educational level, location, and sex showed no correlation (p>0.05) with COVID-19 exposure. Also, the proposition of no significant difference between correlation coefficients of socio-demographics and knowledge was proven otherwise (p<0.05). The regression model (R2=0.420 and adjusted R2=0.404, df=2, 336, F-value=27.012. p=0.00) significantly predicted the synergic contributions of knowledge level and socio-demographics to COVID-19 exposure. 40.04% of the COVID-19 risk exposure can be explained by socio-demographics and knowledge about COVID-19. Synergic contribution of knowledge and socio-demographics proved risk prediction to COVID-19. Traditional factor like age should be decidedly considered and attention should be drawn towards good knowledge about COVID-19 especially its signs and symptoms plus transmission.

Context In the face of further waves of the COVID-19 pandemic it becomes essential to find a balance between protective actions to guard public health and restrictive measures which can collapse our economy. Background As a basis for public health decisions, officials still rely on metrics which were helpful in the beginning of the pandemic but are now not precise enough for a focused and targeted approach to keep the spread of the infection under control. This can lead to public mistrust, “pandemic tiredness”, and can cause unnecessary damage to the economy without having the desired protective effect on public health. Methods This article discusses various metrics, their advantages and caveats, and it provides suggestions for use in a more targeted and risk-based approach, as an alternative to the current “general lock-down” practice. It suggests the notion of including a concept of “risk contacts per area” to better describe the possibility of virus transmission than currently published metrics do. The article also suggests specific analyses of real-world data for identification of populations at risk for severe courses of COVID-19 to allow more targeted protective actions. Discussion Data currently used to describe the COVID-19 pandemic lack important parameters like population density and local likelihood of potentially infectious contacts. The currently often used “all or nothing” approach of shut-down orders needs to be replaced by more sophisticated tactics considering individual local exposure risks and need to be balanced towards metrics on economic short term and long-term impact. In addition, smart analyses of real-world data may contribute to effective protection of individuals at risk.

Mannose binding lectins (MBL), a key molecule in our innate immune response, contributes to host defense against coronaviruses such as SARS-CoV. This article reviews the role of MBL in the innate immune response against coronavirus infections, highlights evidence of MBL’s significance, and suggests dietary MBL supplementation through increased consumption of fruits and vegetables as an accessible and viable approach to minimizing COVID-19 infection risk. Increasing consumption of plant lectins (e.g., eating fruits and vegetables) may reduce COVID-19 risks.

We explore the global evidence of major health crisis potential impacts and the factors influencing the mental health outcomes among the population during the outbreak of COVID-19. Preparation measures for a COVID-19 focus on rapid quarantine of social isolation and economic concerns have risen metal health considerations that become an integrated part of the pandemic outbreak. This outbreak of novel Coronavirus disease (COVID-19) pandemic is swayed an overall 213 countries, areas or territories, with over 2,921,439 confirmed cases and 203,289 confirmed deaths reported till 26 April 2020. This created a lot of strain and fear; fear of falling ill and dying of being infected leading to heightened levels of insurmountable psychological pressure. This scrutiny attempt to assess the widespread outbreaks of COVID-19 on mental health professionals, healthcare workers and general population in association with adverse mental health sequelae like generalized anxiety disorder (GAD), depressive symptoms, insomnia, panic attacks, post-traumatic stress disorder, OCD, suicidal behavior, delirium, psychosis, harmful alcohol consumption, and drug use. There is a need for more evocative exploration to intensify awareness to address the potential psychological and behavioral risks that will remain elevated as long as the COVID-19 pandemic continues in the community. In conclusion, incessant surveillance of the subsyndromal mental health problems for outbreaks should be part of galvanized global action during the quarantine.

In spite of the popularity of open-air waste dumping in Nigeria, it remains a relatively less effective waste management option across the globe because of its associated environmental impacts which includes the release of green house gases (GHGs), persistent organic pollutants (POPs), and metal micro-pollutants amongst others. This study aims to assess the potential environmental risks associated to metals released and vertically delineated across the soil profile within surroundings of dumpsite. Heavy metals in soil samples were acid-digested using the aqua-regia mixture of hydrochloric and nitric acid, followed by instrumentation analysis using the GBC 908 PBMT model atomic absorption spectrophotometer. Contaminated sites showed metal concentrations ranging from 1.493 to 109.460 mg/kg, 0.133 to 4.237 mg/kg, and 5.200 to 25.367 mg/kg for lead, cadmium and chromium respectively, with location 1 land area showing the most contamination. Only soil chromium was observed within regulatory stipulations in all cases. There was significant variation (p < 0.05) between the different sample locations, thereby indicating variations in composition of dumped wastes. Lead and cadmium showed the strongest positive correlation (r = 0.855, p < 0.01) and the application of some heavy metal pollution indicators revealed relatively higher metal loads and degree of contamination, as well as depicting potential ecological risk for soils of location 1. The significant heavy metal contamination of soils in the Tombia-Amassoma waste dumpsite requires that the local environmental sanitation and regulatory authorities take necessary remedial action to forestall the escalation of public health concerns that may emanate from this open-air dump.

Aim Overconsumption of salt contributes to hypertension and increases the risks of cardiovascular diseases. Most studies that investigated salt intake by applying the Health belief model (HBM) have focused on urban settings. This study aims to identify the prevalence of salt overconsumption (>6 g per day) in a rural village in Southwestern China and to determine the association between knowledge regarding salt consumption/HBM constructs and salt overconsumption behavior among village residents. Methods Inthis cross-sectional study, 79 adults aged 18 years and above were interviewed using household-based and face-to-face questionnaires. Salt intake was measured using an electronic balance in accordance with a previous protocol. Results Our finding showed that the average daily salt intake is 11.19±11.14 (mean±SD) g. Moreover, 64.6% of the participants overconsumed salt. None of the participants was aware of the national recommendation for salt intake. Univariate logistic regression showed that i) knowledge about hypertension causing cardiovascular diseases (odds ratio [ORu]=3.02), ii) perceived severity of hypertension as a serious disease (ORu=4.92), and iii) perceived benefit of reducing salt intake to prevent hypertension (ORu=3.52) were unexpectedly positively associated with salt overconsumption behavior. All the studied sociodemographic factors were not associated with salt overconsumption behavior. Conclusions A high prevalence of salt overconsumption was found among residents of rural villages in Southwestern China. HBM was unable to explain the causal relationship between its constructs and salt overconsumption behavior. The extremely low awareness of the national salt recommendation highlighted the urgent need to provide relevant health education in rural China.

Background Globally, about 10 to 25% of the volume of bio-medical waste from hospitals and healthcare institutions presents a serious health risks to patients, healthcare personnel, and anybody who comes in contact with it. The waste management practices in Rwanda healthcare facilities are poor and need improvement. Objectives To assess the knowledge and practices regarding bio-medical waste management among healthcare personnel at Kabgayi district hospital in Southern Province of Rwanda. Materials and Methods A cross-sectional study design was conducted. A total of 200 healthcare personnel were selected randomly out of 400 target population including doctors, nurses, social workers, and cleaners. Structured questionnaire was used to collect data. Descriptive analysis using frequency and proportions were used. Chi-Square test was used to determine the association between the variables and level of significance was set at p ≤ 0.05. Results The study found that about half (49.0%) of healthcare personnel had good knowledge about waste management. We found that the majority of healthcare personel 133(66.5%) had poor practices towards bio-medical waste management. The factors associated with good practice were better knowledge on bio-medical waste management (p=0.013) and older age group (p=0.001). Conclusion/Recommendations The level of in both knowledge and practice towards bio-medical waste management among healthcare personnel was low. Continuing education and training programmes and short courses on bio-medical waste management should be carried out to improve the knowledge and practices towards bio-medical waste management among healthcare personnel.

Background: Chest wall deformities may be managed with skeletal manipulation, which risks life-threatening complications. Custom-made prostheses are a less invasive surgical option, manufactured from silicone elastomer using 3D computed tomographic reconstruction and 3D-printed thoracic models. Methods: All patients undergoing custom-made implants between January 2010 and March 2017 were identified from the prosthetic department records. A retrospective review of the clinical records was performed. Mean follow up period was 1.8 years. A comparison was made with our earlier results from 1995 to 2009. Results: Twenty-six patients underwent insertion of custom-made implants for chest wall deformity. Pectus excavatum was present in 50% (n=13), and Poland syndrome 42% (n=11). All 11 female patients underwent 3D reconstruction and 3D printed models, and 3 of 15 males. Four underwent simultaneous bilateral breast augmentation, and three had staged breast augmentation. Seroma occurred in 27% (n=7), and hypertrophic scar in 12% (n=3). The reoperation rate was 23% (n=6), including autologous fat graft in two patients. Surgical suction drains were used in 42% (n=11) patients, of whom 36% (n=4) developed seroma, compared with 17% (n=2) of those without drains (p=0.08). Conclusions: Custom-made prostheses are an effective and safe option for patients with chest wall deformities. The majority have a short postoperative inpatient stay (81%) and are satisfied with the outcome (77%). Seroma was the commonest complication (27%), and drains did not reduce seroma risk. Single dose intravenous antibiotic prophylaxis is adequate. A minority of patients opt for further aesthetic procedures.

Many researchers have devoted considerable attention to the impact of individual-level factors on child mortality, but little is known about how family and community characteristics affect health of children. Trend in child mortality as well as its determinants, has long been the subject of academic and policy debates. In spite of this, the problem of child mortality remains as daunting as ever. In fact, advancement in medical sciences and the upsurge in information and telecommunication technology equipment have not significantly reduced child mortality in the country, unlike in the West. The Multilevel proportional hazards model for data that are hierarchically clustered at three levels was applied to the study of covariates of child mortality in Nigeria. This study merges two parallel developments of statistical tools for data analysis: statistical methods known as hazard models that are used for analyzing event-duration data and statistical methods for analyzing hierarchically clustered data known as multilevel models. These developments have rarely been integrated in research practice and the formalization and estimation of models for hierarchically clustered survival data remain largely uncharted. The model was estimated using the Newton-Raphsons numerical search approach. The model accounts for hierarchical clustering with three random effects or frailty effects. We assume that the random effects are independent and follow the Exponential and Weibull distribution. The results indicate that bio-demographic factors are more important in infancy while socioeconomic factors and household and environmental conditions have a greater effect in childhood. Furthermore, there is significant variation in child mortality risks even after controlling for measured determinants of mortality. Also, factors that fall under family and community level are more significant indicating that child survival is most controlled or determined by family and community factors and variables at the child level is not weighty. This suggests that there may exits unobserved or unobservable factors related to mortality.

This review is designed to look at a prospective evaluation of the use of the femtosecond laser and manual incision standard cataract surgery in one center with one surgeon focusing on visual outcomes and complications. Multiple studies support both benefits, risks, alternatives, and differences between manual capsulotomy combined with standard manual incision cataract surgery and cataract surgery employing the femtosecond laser in conjunction with routine phacoemulsification. The purpose of this study was to evaluate early postoperative outcomes using a prospective evaluation of cases from one surgeon over the course of two years from 2015-2017. The first group of cases involves 2134 eyes comparing phacoemulsification time in seconds (PT), ultrasound time in seconds (UT), and cumulative delivered energy (CDE). The second group of cases involves 1913 eyes that were Lens Opacification Classification III similar and without other ocular or lenticular abnormalities. Finally, a subgroup from the latter group (n=150) were evaluated over the course of two days and postoperative 3-hour examinations (visual acuity) were compared.

Wind turbines are often perceived as benign. This can be attributed to the population majority dwelling in urban locations distant from most wind turbines. Society may understate the risk to individuals living near turbines due to an overstatement of the perceived benefits of turbines, and an understatement of the risk of injury from falling turbine parts, or shed ice. Flaws in risk calculation may be attributed to a less than fully developed safety culture. Indications of this are the lack of a comprehensive industry failure database, and safety limits enabling the industry growth, but not protective of the public. A comprehensive study of wind turbine failures and risks in the Canadian province of Ontario gives data to enable validation of existing failure models. Failure probabilities are calculated, to show risk on personal property, or in public spaces. Repeated failures, and inadequate safety separation show public safety is not currently assured. A method of calculating setbacks from wind turbines to mitigate public risk is shown. Wind turbines with inadequate setbacks can adversely impact public health both directly from physical risk and indirectly by irritation from loss of safe use of property. Physical public safety setbacks are separate from larger setbacks required to prevent irritation from noise and other stressors, particularly when applied to areas of learning, rest and recuperation. The insights provided by this paper can assist the industry to enhance its image and improve its operation, as well as helping regulators set safety guidelines assuring protection of the public.

A cohort of Pony Club horses was observed for 13 months with data collected from owner-kept diaries and monthly property visits. All horses studied had access to pasture for all or part of the day. Whilst paddock size was seldom limiting, pasture degradation was evident and observed pasture mass and composition varied greatly. Horses’ body weight indices and body condition scores also varied greatly, closely matching seasonal variations in pasture mass. Increments in bodyweight varied in a non-linear fashion with body condition score. Most horses experienced additional year-round hand-fed supplementation and half of the study horses recorded body condition scores greater than 3.5 out of 5. This suggests that the owners of Pony Club horses did not rely on pasture as the sole source of nutrition, even though, based on estimated energy demands, well-managed pasture can meet the energy requirements of Pony Club horses. Furthermore, the fact that owners appeared not to make horse feeding decisions based on body condition score resulting in obesity, raises health and welfare concerns in this cohort of horses. The inappropriate feeding of supplements observed during times of high pasture growth was a concern. Whilst the ideal pasture for Pony Club horses has not been described, it is likely to differ to those considered ideal for broodmares and other livestock because of these unique health risks associated with high levels of non-structural carbohydrate content in improved pasture species. This study highlights the need to educate owners about recognising unhealthy body conditions of horses and better managing pastures and pasture access to reduce the risk of obesity related disorders, whilst at the same time reducing pasture degradation and supplemental feed costs

Introduction The practices of having extreme and permanent body modifications as in tattoos and scarifications are gaining popularity among youths especially those in the universities. Not minding the unbearable and painful pressure of sharp objects on the tissues and the risk of being infected with blood transmitted infections including HIV, youths still engage in these practices. This study aimed to examine the extent to which university students are aware of the risks of using improperly sterilized and disinfected sharp objects. Materials and Method First year students in three universities, Federal, State and Private Universities were used for the study. A random sample of ninety (90) students made up of 30 students from each of the three universities studied was used. Drama was used as an intervention that will create awareness on risks of utilizing sharp objects in making scarifications. The completed copies of self-administered pre- and post-drama questionnaire were collected and analyzed quantitatively using Tables and percentages. Results Results showed that a good number of students 29 (97%) in Michael Okpara University of Agriculture (MOUA) , 28(93%) in Abia State University (ABSU) and 27( 90%) in Rhema University viewed sharing sharp objects like razor blades and syringes as risk to blood transmitted infections especially HIV. A total of 28(31%) of students both males and females in MOUA, ABSU, and Rhema had marks (scarification and/ or tattoos) on the body. The main reason for having the marks was for traditional identification and this was more among students in MOUA than in others. Conclusion Based on the results of the study, drama proved to be a valuable and timely intervention strategy that created awareness among university students on the risks of using sharp objects to make marks on the body.

Objective: Presentation of rare case report of primary non-Hodgkin Lymphoma of temporal bone secondary to immunodeficiency after prolonged steroid administration in a diabetic patient. Then review the literature of similar case reports. Method: 49 years old female presented with hearing loss, facial paralysis and otalgia. Biopsy revealed high grade non Hodgkin’s B-lymphoma. She underwent chemotherapy and had remarkable response. Result: Rapidly progressive deafness, facial paralysis and otalgia are common presentations of external canal Non-Hodgkin lymphoma. The disease is common in middle age, females and has a fair response to chemotherapy, good to radiotherapy. Surgery is an alternative method in isolated lesions or recurrent cases. Conclusion: High dose steroid and type II diabetes are potential risks for acquired immunodeficiency. External Auditory canal lymphoma is uncommon sequel. Chemotherapy is very effective in treatment of isolated cases without B symptoms

Objective: Demographic analysis of intrauterine deaths in North-Eastern Hungary with national and international comparison. Materials and Methods: The authors collected data from the National Bureau of Statistics’ 1996-2014 database to assess frequency, gestational age, maternal age and education for six counties of the region. 722 individual cases were analyzed. A regional survey was initiated to collect more detailed data on living environment in the region between 2010 and 2014 through community midwifery services records. Results: Data over 20 years showed most intrauterine deaths (Perinatal mortality, Late fetal death, Stillbirth] occurred between 24th and 36th weeks of which 35% occurred in the North-Eastern region of Hungary. The causes of intrauterine deaths were placental abruption, cord accident, placental insufficiency, malformations and intrauterine infection. Detailed analysis regarding attendance at either the Obstetricians or the community midwifery services, the patient’s medical history and the patients’ compliance were reported, compliance in 1% completely lacked. Gravidity and multiparity were associated risk factors. A significant proportion was associated with teenage pregnancy, low maternal education, smoking risks, unemployment, dependence on social support, unhygienic environment and smaller accommodations. Lack of cooperation during antenatal care was significant. Conclusion: Frequency and distribution of intrauterine deaths in North-Eastern Hungary show a similar picture as those of socio-economic indices. The unfavorable trend came to an end in 2015, however the national statistics did not show any improvement. The solution to the problem seems to be independent of the service provision, therefore, socio-economic development of affected counties is warranted, and financial incentives and/or government aid provided during pregnancy may improve future perinatal outcomes.

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.

The global popularity of soccer has led to widespread tendency towards this sport. Because of the convenience of using artificial surfaces, the rapid growth of using these surfaces led to concerns about the declining performance of the players. The aim of this comprehensive review is to study the difference between the performance of players on different playing surfaces and the risk factors for use of artificial turf compared to natural grass. A literature search of valid scientific databases such as Science Direct, PubMed and Jstor by searching keywords was performed. In total, more than 6,000 articles were retrieved. After the preliminary selection process, the final analysis was performed on a total of 76 articles. Results: Mechanical properties of artificial grass have a significant effect on the average time of sprinting, the best time of sprinting and maximum speed. The numbers of sliding tackles on artificial turf were lower compared to natural grass. Artificial turfs exposed hardness, elasticity and high friction. The characteristics of artificial grass have changed over time and increased the probability of injuries. There was no significant difference between the overall risks of acute injuries in soccer players performing on artificial turf compared to natural grass. The amateur, young and female soccer players had rated lower injuries on artificial grass. But the rate of injuries in elite soccer players were higher on artificial grass and hence they are not found of playing on such playing surfaces.

Second-generation antipsychotics have relatively recently become available in long-acting intramuscular formulations (LAIs) and have been receiving a substantial amount of pharmaceutical industry promotion on the grounds that they improve treatment adherence in patients with psychotic illness. LAIs do have some drawbacks, however, which is the topic area covered by this review. A Global Scholar search of the nursing and medical literature reveals several factors that can negatively impinge on the clinical efficacy of LAIs: 1. The extent of training of injection personnel 2. The quality of surveillance of patient symptoms and side effects 3. The skilled use of the full range of injection techniques 4. The extent of drug accumulation over time 5. The potential loss of drug dose flexibility 6. The impact of exercise and temperature on drug distribution 7. The burden of the medication routine and the social burdens of LAIs 8. The safety of LAIs during pregnancy 9. The perceived coerciveness of LAIs 10. Issues of overdose and polypharmacy 11. Issues of cost 12. The important issue of responsibility for self-management of illness. Although the evidence is clinical and anecdotal, LAIs appear to work well for many patients, but their drawbacks are not negligible. Clinicians need to weigh individual risks and benefits when making treatment decisions.
