Persons with osteoarthritis often have signs of reduced muscle strength. Some studies suggest that this strength could be improved with exercise. However, does this form of therapy improve the disease status as assessed by improvements in cartilage viability, a hallmark of the disease? This brief describes the possible usage of exercises in general, plus those known to improve strength and function, and reduce pain and whether structural impacts that favor or impede disease regression have been observed in this context among the older osteoarthritis adult population. Since exercise may also do harm, rather than good in osteoarthritis management if excessive, contra indicated, or suboptimal, what is the consensus in this regard in 2024?

This exploratory study investigates factors and consequences of underdiagnoses or late diagnoses of attention deficit hyperactivity disorder (ADHD) in females favoring males in the referral, diagnosis, and treatment processes resulting in gender disparities. A literature review in PubMed, PsychINFO, PsychArticles, and PsychiatryOnline from 2010 to 2023 underscores significant implications of delayed ADHD diagnosis in females, hindering timely access, support, and interventions during critical developmental years. Factors associated with underdiagnosis of ADHD among girls include gender differences in symptomology presentation, comorbidity, and gender bias among parents, teachers, and healthcare providers. We highlight the role of ethnicity and cultural factors. This bias prevents girls from receiving necessary ADHD support and treatment, impacting their health, social, and economic outcomes into adulthood. We summarize strategies to urgently address gaps in ADHD research and practice. Raising awareness among communities, healthcare providers, educators, and parents is vital to alleviate these gender disparities. By illuminating factors contributing to delayed diagnoses, the study informs policymakers and stakeholders, facilitating targeted interventions to improve early detection and treatment outcomes for females with ADHD.

Knee joint osteoarthritis, a chronic condition resulting in considerable disability, particularly in later life, not only impacts life quality significantly and severely, but is also strongly associated with the persistence of intractable pain, depression, helplessness, and a high falls injury risk. This narrative overview synthesizes the knowledge base regarding painful knee osteoarthritis and what is known about Tai Chi exercise participation in the context of reducing knee joint disability and its associated risk of one or more injurious falls, as well as pain and depression. To this end, all relevant articles published in the English language on the topic were sought. While most reports rely on Eastern observations, rather than Western medicine studies, collectively, these data reveal that Tai Chi practiced widely in Asia for many centuries may have an enormous positive impact on reducing distress and increasing function and autonomy among older adults living in the community and diagnosed as having knee osteoarthritis. They specifically suggest the increasing numbers of older adults diagnosed as having knee osteoarthritis can safely practice selected Tai Chi exercises with the expectation that consistent applications will enhance mobility, reduce pain and depression, plus instability and possible injurious falls, while reducing fatigue, even if surgery is forthcoming.

Dams are built to produce electricity, store water for irrigation, control flood hazards and other uses. The operation of dam has a complicated problem, which includes multiple decision variables, several conflicting and contradictory objectives together with significant uncertainty and risk. The objective of this study was to make an impact assessment that Fincha’a-Amarti dam operation can bring on the downstream activity. Fincha’a-Amarti dam downstream irrigation water requirement was done by using CROPWAT software. The SWAT model was also used to model the watershed and simulate the flow. Meteorological data and spatial data of the study area were used as an input of the model. The meteorological stations considered were Shambu, Fincha’a, Homi, Nashe and Harato. The study shows that downstream water requirement greater than the existing downstream water release during the months of: January, February, March, April, May, September, October, November and December; but existing water release is greater than downstream water requirement during wet season only. Therefore, the study concludes that there is downstream water stress except during wet season.

Background Osteoarthritis, a serious joint disease, said to represent a generally declining state of wellbeing and function among many older adults has been shown to be affected to a considerable degree by various negative beliefs and inactions rather than degradation alone. Aim This review examines the case of depression as this pertains to the older adult with osteoarthritis of one or more joints. Specifically, the most up to date information on this topic was sought, as care improvements over the past decade have not shown any impactful population wide results. Method Reviewed were relevant 2021-2022 research and review articles specifically pertaining to what is being observed currently by researchers as far as osteoarthritis-depression linkages goes, as these may reveal opportunities for more profound research, and practice-based endeavors. Results In line with 60 years of prior research, it appears a clinically important role for depression in some osteoarthritis cases cannot be ruled out. It further appears that if detected and addressed early on, many older adults suffering from osteoarthritis may yet be enabled to lead a quality life, rather than a distressing and excessively impaired state of being. Those older osteoarthritis cases requiring surgery who suffer from concomitant depressive symptoms are likely to be disadvantaged in the absence of efforts to treat and identify this psychosocial disease correlate. Conclusion Providers and researchers are encouraged to pursue this line of inquiry and begin to map clinical osteoarthritis measures with those that can track cognitive patterns, musculoskeletal, features and inflammatory reactions along with valid depression indicators among carefully selected osteoarthritis sub groups.

Garden egg nutritional values are numerous. However, few nutritional and epidemiological data exist on the impacts of garden egg consumption on diabetes control. In this experimentally-control designed nutritional study, the effects of scarlet garden egg species (Solanum aethiopicum L.) on lipoglycemic profile, weight control and, pancreas histoarchitecture in diabetic male Wistar rats were examined. Twenty-One adult male Wistar rats inducted with diabetes were randomly categorized into three groups (n = 7, each): Diabetic control (DC); Diabetic treated with aqueous extract of garden egg (DEE) and Diabetic fed with garden egg-supplemented diet (DSE). Animals were fed for six weeks according to the experimental design. Glycemic status and body weights were assessed twice weekly while lipid analysis was conducted at the entry and 6th week of the study. Oral glucose tolerance (OGT) test was conducted. Gross analysis and tissue histology of the pancreas were assessed by Hematoxylin and Eosin (H&E) staining technique. Statistical analysis was done using analysis of variance, and the results were expressed as mean ± S.E.M. at P < 0.05. Garden egg reduced mean body weight gain (DSE: 14.53%; DEE: 10.58%; P value = 0.04) and decreased blood glucose concentrations (DEE: 37.33%; DSE: 18.68%; P = 0.03) with corresponding improved lipid profile, glycemic tolerance and control (DEE > DSE) and, preserved pancreas histoarchitecture in diabetic Wistar rats. Solanum aethiopicum (garden egg) consumption (as fresh fruit or supplemented diet) preserves pancreatic tissue histoarchitecture and improves lipoglycemic profile and weight control in diabetic Wistar rats.

Background The pandemic has disrupted the lives of many globally including persons with disabilities. These disruptions are universal. However, the vulnerable communities are more affected. Purpose The study examines impacts on persons with disabilities to share knowledge and inform interventions that ensure persons with disabilities are supported. Methodology The study is a systematic literature review using different search engines to search for scholarly articles all over the globe. Results Persons with disabilities have been negatively impacted in numerous ways: lack of access to healthcare services, inadequate rehabilitation services, increased human rights violation, stigmatization and discrimination, increased risk of dying, being subjected to violence, losing financial income, lack of access to education and treatment, increased in neglect and traumatization, poverty, lack of access to food, decreased in community support; and worse of all, in comparison with the overall population, the death of persons with disabilities during the Covid-19 is higher. These impacts were precipitated by inaccessible built environment and sense of touching, lack of disability sensitive policies, increased prevalence of risk factors, difficulties in adhering to WHO recommendations, pervasiveness of underlying health conditions, lack of disability-friendly information and inclusive intervention, national budget cuts; and poorly funded institutions. Conclusion Persons with disabilities have been negatively impacted due to many risk factors peculiar to them.

Background Falls injuries continue to contribute to numerous premature deaths as well as high disability levels, and excess morbidity rates among older adults, worldwide. But can vitamin D account for excess falls injuries among older adults? This review specifically focuses on what is known about vitamin D in the context of postural stability or balance control, both fairly consistent independent predictors of falls among older adults. Methods and Procedures Drawn largely from a review of current relevant English language peer reviewed research publications published over the last 10 years detailing the relationship between vitamin D levels and balance control among the elderly, as this relates to falls injuries, evidence for any emerging consensus on this controversial topic was sought. Used to conduct the search were various key word combinations including: falls injuries and older adults, vitamin D or vitamin D deficiency and balance or postural control. The database used predominantly to provide input into this largely descriptive assessment and narrative overview was PUBMED. Results The prevailing data show falls injuries currently constitute a widespread costly major impediment to successful aging and longevity for many older adults, despite numerous efforts to prevent this disabling set of events over the past two to three decades. However, no consistent association appears to exist between the variables of vitamin D, falls, and balance attributes in the older population-despite years of research, regardless of study approach, and a strong rationale for hypothesizing a clinically meaningful relationahip. Conclusion It is not possible to arrive at any universal recommendation concerning the value of vitamin D supplementation as regards its possible influence on balance capacity among older adults in the realm of falls prevention efforts, as has been frequently proposed. However, until more definitive research is conducted, there still appears sufficient justification for considering the screening of vulnerable aging adults for serum vitamin D levels, along with balance impairments, and intervening as required in the case of deficits in either or both of these possible falls determinants.

Background to the Issue Many older adults, including those already suffering from chronically painful disabling osteoarthritis of one or more joints remain more susceptible than healthy age and gender matched adults to the COVID-19 corona virus. Aims This report sought to examine what has been published in 2020 on this health condition from the perspective of the variable of widely imposed social isolation strategies designed to mitigate the spread of this highly infectious disease, and to especially keep older community dwelling adults ‘safe’ from infection. Methods Reviewed were all articles published in 2020 in PUBMED from January 1-December 24, 2020 on osteoarthritis and COVID-19 isolation impacts, plus relevant past osteoarthritis and isolation literature among older adults. The focus was on ascertaining how social isolation and distancing strategies might impact current community-dwelling adults diagnosed with osteoarthritis and whether more should be done specifically to mitigate any potentially preventable ‘socially’ induced negative health impact among this group, in spite of the laudable goals of this public health strategy. Results Older adults with osteoarthritis living in the community who are asked to self-isolate, may incur more osteoarthritis pain and disability than would otherwise be encountered if actions taken to counter this possibility are not forthcoming. Advocated over and above basic care approaches are several psychosocial strategies including the role of mobilizing various forms of social support. Conclusion Data indicate a need for concerted thoughtful and immediate attention to offset isolation, fear, and anxiety and depression effects as part of a carefully devised integrated plan of management to reduce excess osteoarthritis disability, as well as excess COVID-19 risk among otherwise free living older adults already compromised by osteoarthritis.

Public health professionals working in rural communities are aware of the health disparities which result from lack of physicians, limited services, and income during the pandemic. Also they are aware that some populations are more vulnerable than others. People in the rural areas are experiencing problems on their physical, social and economic life styles because the pandemic is exacerbating some inequities. Individuals especially women and children in the rural areas are facing barriers in accessing health care services due to lack of resources and availability of health care providers in the communities. With COVID-19, women are less likely to seek services, including sexual and reproductive health services. Such services may be postponed to limit exposure to COVID-19 infection. This is particularly disturbing because in addition to the women maintaining their own health, they are also responsible for taking care of the mental, emotional and physical health needs of their families as well as all domestic responsibilities. As such, women in rural settings face special challenges as a result of these significant roles they play. Therefore, the impacts of COVID-19 are exacerbated on women by virtue of their sex and the roles they play in the family. This is a qualitative study that reviewed the reports of the 36 health care professionals under the aegis of members of COVID-19 committee working in partnership with state government to control, prevent and cushion the effects of COVID-19 in the society. This study is therefore, a summary of the observations of the COVID-19 committee members made up of 10(27.8%) females and 26(72.2%) males. The study focused on exploring how individual lifestyles in the rural areas have been affected in the face of COVID- 19 pandemic by identifying the vulnerabilities in social, political and economic systems which can amplify the impacts of the pandemic. Findings showed that preventive measures like lockdown and social distancing rules, wearing of face mask, hand washing with soap, and environmental cleanliness were not observed. The study noted that health seeking behaviours, sexual and marital life including income, education, employment and social interactions were all negatively affected. Most hospitals were battered and health care professionals boycotted the hospitals for fear of being infected. It was found that lack of health workers in the hospitals caused a good number of individuals to engage in self-medications. Also most pregnant women delivered their babies at home and few with traditional birth attendants. Some of the women who had deliveries at home experienced complications during and after delivery. Unfortunately, the report showed that governments’ financial supports to these women and their family members were insignificant as the government was more concerned with mitigating the spread of COVID-19 than assisting women to have safe deliveries. Therefore, the vulnerable groups especially women, children, and the elderly who experienced threats to their safety and wellbeing as a result of the services that were disrupted during the pandemic, should be assisted so as not to lose their lives to preventable diseases.

The environmental impacts of waste disposal of polyethylene bags and seasonal variation of polyethylene disposal in Gusau City of Zamfara state, Nigeria was investigated. General public waste disposals from homes, schools and daily markets, were randomly selected for data collection. The data showed that polyethylene waste is generated more in the dry season than the wet season. The result also showed that table water sachet has 75% disposal. This is because, sachet water is cheap and consumed throughout the year with very little seasonal variation while at homes and markets also, displayed a very interesting pattern. The study revealed that in the market, polyethylene for table water sachets (10%) was the least, followed by ice cream sachets (6%), assorted items (5%) and biscuits wrappers (4%). On the other hand, the results showed that, at home, polyethylene for assorted items was the highest (61%), closely followed by biscuit wrappers (20%), table water sachets (14%) and ice cream wrappers (5%) respectively. Polyethylene waste poses various threats to public health and adversely affects flora and fauna as well as the environment especially when it is not appropriately collected and properly disposed. And based on this research, it was found that most of the public do not know the advantages, disadvantages and the health effects of rampant and improper disposal of polyethylene bags. It is concluded that aggressive campaign and enlightenment of the masses on the threats posed by polyethylene bags pollution should be carried out to prevent further negative environmental impact.

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.

Cassava is the fourth largest staple food after rice, wheat and maize. Cassava is produced in the tropical and sub-tropical countries. Currently, the global production of cassava is about 215,436,496 tons. Out of these, Nigeria accounts for 20.3%, being the largest producing nation. During processing of cassava flour (Gari), three main wastes are generated including cassava mill effluents (CME), solid and gaseous emission. This paper reviews the impacts of CME in Nigeria. The study found that CME’s physicochemical quality often exceeds the limit for effluents discharge onto land and surface water as recommended by Federal Environmental Protection Agency (FEPA), Nigeria. CME alters the quality of soil and water with regard to physicochemical, heavy metal and microbial characteristics. CME can induce toxicological effects on the environments and its biota including humans, fisheries, flora and fauna. The impacts are mostly associated with physicochemical (viz: odour, cyanide, acidic, dissolved oxygen, biological and chemical oxygen demand, conductivity) and heavy metals characteristics. Therefore, there is the need for treatment and sustainable management strategies of CME through biotechnological advancement.

Chemical insecticides have been the primary method used by farmers to control pests. However, their negative environmental impacts, harmful effects on beneficial insects and human health, and prohibition in organic farming systems have driven the search for natural alternatives with insecticidal properties. These alternatives provide a safer and more sustainable way to control insect pests. Medicinal plants and their constituents play an important role in pest management. For example, ginger (Zingiber officinale) extracts contain bioactive compounds with insecticidal activities. The objective of this work was to track the population of the green peach aphid (Myzuspersicae) on pepper crops in a greenhouse, identify the active ingredients in ginger extracts, and evaluate the insecticidal effects of three concentrations of ginger-derived aqueous and essential oil extracts against M. persicae on pepper plants under laboratory and greenhouse conditions. The results demonstrate that M. persicae grows rapidly on pepper crops under greenhouse conditions, reaching high densities on leaves. The ginger extract contains two active ingredients with insecticidal effects against this pest. The significant reduction in aphid (M. persicae) populations indicates that Z. officinale aqueous extract (150 mL/L) and essential oil (2 mL/L) have strong potential for the biological control of this pest under greenhouse conditions. Thus, the use of ginger plant extract emerges as a promising alternative for reducing M. persicae infestations on pepper plants.

Sudan's ecological landscape is characterized by various zones, including deserts, semi-deserts, and savannas, which host a diverse array of forests, rangelands, and numerous plant and animal species. However, the sustainable management of these resources is becoming increasingly challenging due to human activities and the impacts of climate change. This article presents the results of a research project focused on monitoring and documenting biodiversity in Sudan's semi-arid regions, particularly emphasizing insect diversity. Insects are vital for maintaining ecosystem health through processes such as nutrient cycling, decomposition, pollination, and acting as natural predators to pests. Field surveys were conducted across three Sudanese states—North Kordofan, Gezira, and Khartoum—to assess the diversity of flora and fauna. Specifically, El Rawakeeb semi-arid land in Khartoum state was investigated, which comprised three sites with varying soil elevations: a hilly site at 420 meters above sea level, a flat site at 416 meters, and a valley site at 411 meters. Researchers utilized direct collection methods and butterfly nets to gather insect specimens, which were subsequently preserved and identified for further analysis. Diversity indices, including Simpson’s Diversity Index, Shannon-Wiener Index, and Margalef Richness Index, were computed to compare the biodiversity of these sites, along with metrics for evenness and species richness. Permanova analysis was carried out for insect variation between the study sites. A total of 1541 insect specimens were gathered from El Rawakeeb, encompassing 34 species distributed across 21 families and 9 orders. The order Lepidoptera exhibited the greatest number of species (35.29%), followed by Coleoptera (20.59%). The orders Neuroptera, Orthoptera and Thysanoptera recorded the fewest species (2.94% each). From the hilly site, 514 insect specimens were collected, representing 9 orders, among which Hymenoptera included 4 species, while Lepidoptera had 3 species, and Odonata, Orthoptera, and Thysanoptera each had 1 species. The highest individual counts were recorded for Copriniklobe (dung beetle), Dacus longistylus (fruit fly), Camponotussp. (carpenter ant), and Anax ephippiger (dragonfly). In a flat site, 484 insect specimens were collected, classified into 15 species, 12 families, and 7 orders. The highest individual counts were noted in four species: Onthophagusnuba (dung beetle), Dacus longistylus (fruit fly), Camponotussp. (carpenter ant), and Anax ephippiger (dragonfly). In a valley site, 543 insect specimens were collected, categorized into 17 species, 16 families, and 9 orders. Insect Diversity in three research sites. Simpson's Diversity Index revealed varying levels of insect diversity across the three sites. The valley site exhibited the highest diversity level with an index score of 0.857, followed by the flat site at 0.826, and the hilly site at 0.819. The Shannon diversity index of 2.22 indicated the highest diversity among the three sites, suggesting a relatively diverse insect community. The relative abundance of insects was greatest in the valley site at 35.24%, followed by the hilly site at 33.35%, and the flat site at 31.41%. The Margalef Richness Index indicated a moderate level of richness in the insects collected from the three locations. Certain insect species were found in some sites but were absent in others. The PERMANOVA revealed notable variations among the three study sites (F = 2.24, p-value = 0.035).

Background Masculinity remains a dominant phenomenon in the social construction and performance of male roles in society, influencing economic participation, access to essential services, and decision-making at household levels. Research focusing on women's empowerment has been extensively done, with little focus on how masculine support from men impacts the well- being of married women. This study examined how married women perceive male support in the context of economic, emotional, and physical support in Luwero district, Uganda. Methods This was an exploratory qualitative study conducted among married women aged 18 to 49 years. Key informant interviews were conducted with community women aged 30 to 40 years, and village health teams aged 30 to 40 years. The study participants were purposively selected based on the inclusion criteria of the study. Data were analysed using content analysis and the findings were presented using themes/sub-themes along with participant quotes. Results We interviewed married women aged 18 to 49 years old, with the majority falling in the age category of 30 to 39 years (59.1%) and were married for over 6 to 9 years (45.5%). Concerning the key informants, 2 VHTs were aged between 30 to 39 years (66.7%), and the women leaders were aged between 30 to 40 years (60%). About male support among women, nine subthemes emerged, including low engagement in family affairs, lack of financial support and cultural traditions, women’s insecurity, emotional neglect, women as providers of emotional support, lack of emotional responsiveness, emotional support driven by institutional policy, shared domestic responsibilities, and lack of physical presence during sickness. Generally, male support towards women was found to be lacking. Conclusion Male support among married women remains insufficient, contributing to emotional strain and unequally distributed responsibilities. Strengthening community awareness and engaging men through tailored programs can foster a more supportive domestic environment.

Interspecific predation within Odonata is a critical yet underexplored aspect of their ecological interactions. This short communication reports a novel observation of Ischnura senegalensis preying upon Agriocnemis pygmaea in rice fields at the Faculty of Agriculture, Rajarata University of Sri Lanka. Documented on March 22, 2024, during the reproductive stage of the rice field, the predatory event involved a female I. senegalensis feeding on the head of a female A. pygmaea. Predation, characterized by the use of mandibles and lasting at least 15 minutes, reveals significant predatory efficiency and behavioral specialization. This observation fills a gap in the understanding of I. senegalensis feeding behavior in Sri Lanka and contributes to the broader knowledge of Odonate predator-prey dynamics. The findings highlight the importance of these interactions in maintaining ecological balance and suggest further research into the impacts of such predatory behaviors on agricultural ecosystems.

Reproductive performance is an essential trait of cows in dairy cattle. The effect of different factors on reproductive performances and sex ratio difference in dairy cattle were not well documented in Ethiopia. In this research, cross-sectional study was conducted from December 2021 to June 2022 in Hawassa city to assess reproductive performances and effect of breeding methods on sex ratio difference of newborn. Questionnaires and observational study were used to collect data. In this study, the mean+SE of age at first service was 17.53+0.035 with difference of relatively one month from onset of puberty. The mean number of services per conception was higher in animals breed naturally (1.87+0.056) as compared to AI (1.69+0.049). Higher conception rate of 74.26% was obtained in age group of <4years as compared to old age >6years at rate of 4.11% with statistically significant difference (P<0.05). Animals with medium level of milk production (15-20L/day) more conceived to first service 43.14% than higher milk production group (20-25L/day) with 35.59%. The presence of reproductive problems significantly affect conception rate to first service with higher conception rate of 54.47% in negative animals and 22.41% in animals with reproductive problems. Conception rate was increased with increasing number of services in both breeding types. Sex of newborn was not significantly affected by breeding methods used and difference in the study area. Generally this research found that reproductive performances and use of AI in the study area were satisfactory even though age, level of milk production and presence of reproductive health problems had significant impacts on performances. In order to sustain and improve reproductive performances age, reproductive health problems and breeding management should be considered. Therefore, reproductive health management and application of AI for genetic improvement should be well practiced to improve dairy cattle reproductive performances.

Helminth parasite infections in sheep are of major veterinary importance in many agro-ecological zones and are a primary factor in the productivity of sheep. The main objective of this study was to determine helminth parasites prevalence and their economic loss caused on sheep with its control approach at the study area. A cross-sectional study using a simple random sampling procedure was used to study helminth parasite identification at Gudaya Bila district during 2022 in two seasons of the year: winter (January - March) and summer (June - August). Out of 384 sheep chosen at random sampling from five Kebeles in the Gudaya Bila district (Welenelemu, Harogodisa, Chalejima, Hagelogidami, and Bila) that underwent flotation and sedimentation procedures, about 149 were infected by ay helminth parasites, with an overall prevalence 38.8%. Regarding the distribution of helimenth parasites at the class level, the prevalence was 13.9%, 11.7%, and 3.9% in trematoda, nematode, and cestoda, respectively. The helminth species that had highest prevalence were Fasciola species (19.5%), Haemonchus species (14.76%), Strongyloides species (10.74%), and Schistosoma species (9.4%), and those that had the least prevalence were Moniezia species (6.04%), Paramphistomum species (5.4%), Taenia species (4.02%), Nematodirus species (3.3%) and Trichostrongylus species (1.34 %). The summer season was favorable for helminths parasite transmission. The prevalence of helminths in the summer season was 98 (25.5%), and in the winter season it was 51 (13.3%). The study shows that the gastrointestinal helminth parasite was a major health problem and had an impact on the production of sheep in the study area. Therefore, a detailed study should be conducted to identify the parasite at the species level, and further investigation will be needed to study the association of the prevalence of helminth parasites within age, sex and the agroecology of sheep in the area. Then educating the people about the impacts of helminths is needed to control them.

This study explored concerns and unsolicited advice relating to miscarriage shared on multiple social media platforms for mentions of questions, advocacy, medical advice, conflicts of interest, and terminology used to describe miscarriage. Public social media posts in English from January 1st, 2019 to June 30th, 2021 were searched using keywords related to miscarriage. A dataset of questions, advice, conflicts of interest, and terminology used was created from eligible posts determined by inclusionary and exclusionary criteria. The dataset was analyzed to identify themes and calculate statistics. Approximately 1000 posts were reviewed and 149 posts were found eligible for analysis. Of the total, 116 posts included advice and a subset of 71 posts offered questions. A total of 152 mentions of advice were identified from the total eligible posts with 82.9% of advice related to advocacy for destigmatizing miscarriage, enhancing community support, or expressing grief. 17.1% of posts offered medical advice eligible for evaluation of which 73% were accurate across all platforms. From the dataset, 103 questions were analyzed for common themes. The four most common themes of questions included grief, self-blame, quality of post-miscarriage counseling in different care settings, and inadequate medical counseling. This study indicates that women who experience miscarriage have many unanswered questions and powerful feelings relating to grief and self-blame that could have long-term impacts. Social media has become a place for women to self-advocate and connect with others for support, from which clinicians could increase their understanding of women’s unmet needs.

Aim This review examines the research base concerning hand osteoarthritis and changes in muscle mass and quality known as sarcopenia and the possible use of vitamin-D supplementation for reducing this potentially adverse functionally disabling state. Methods Publications detailing a possible link between hand osteoarthritis manifestations and sarcopenia, plus those discussing vitamin D as a possible intervention strategy for minimizing sarcopenia in the older adult were systematically sought and reviewed. Results Collectively, data reveal hand osteoarthritis in the older population is common, and is possibly affected by age as well as disease associated muscle mass declines. Vitamin D, a powerful steroid required by the body to foster many life affirming physiological functions may help reduce the degree of any prevailing sarcopenia and thereby some degree of hand osteoarthritis disability. Conclusions Older individuals with hand osteoarthritis, as well as healthy older adults at risk for sarcopenia are likely to benefit physically from efforts to clarify the extent of this association and if indicated, to examine and intervene thoughtfully to maximize muscle composition as well as safe vitamin D levels where subnormal. Researchers can make highly notable impacts in multiple spheres in this regard and are encouraged to do so.

The study aimed to assess the oral health condition and its impact on the quality of life (QoL) among a sample of Yemeni population. The study including 256 individuals who responded to the Oral Health Impacts Profile (OHIP) through completing a face-to-face survey of the OHIP-14 Arabic version. The data were collected by one dentist trained in the terms of oral health-related quality of life (OHRQoL). The study revealed that the impact of OHRQoL among the study sample was found with a weighted OHIP-14 score of 1.1 (±0.9). Physical pain (3.7±2.3), followed by physical disability (2.4±2.2), and psychological disability (2.1±2.3) were the highest scoring. A significantly higher effect (p < 0.05) was found for the adults (18-44 years old) compared to those elderly individuals (> 64 years). The OHRQoL was better in male than in female and in employees than in both pensioners and un-employees. Females had a significantly higher effect when compared to males in the OHRQoL (p < 0.05). The unemployed subjects were significantly higher than those pensioners and employees in the OHRQoL (p < 0.05). The OHRQoL was also better in subjects with higher income and education than those participants with low. However, there were no significant differences for OHRQoL with respect to the educational level and monthly income of participants (p > 0.05). Conclusion, the quality of life is greatly affected by the oral health conditions of the elderly. This impact of oral health on quality of life has an association with individual and contextual variables.

Background Many older adults remain vulnerable to COVID-19 infections. They are also often at risk for frailty and poor health outcomes. Aim This exploratory review examines the correlates of long COVID and frailty and their association insofar as the older adult’s wellbeing may be jeopardized. Methods and procedures Articles that emerged between January 1 2022 and 2023 in major electronic data bases that addressed the current topic of interest were sought using the key words: Long COVID and Frailty. Those deemed relevant were duly downloaded, analyzed and summarized in narrative form. Results A high proportion of older adults can be expected to remain vulnerable to COVID-19 long term impacts, plus new variants of infection, along with frailty as both an outcome and mediator. Many too are at risk for persistent long COVID-19 complications and a low life quality if more concerted preventive and rehabilitation efforts to avert frailty early on are not forthcoming in a timely manner. Conclusion Prompt and continuing frailty assessments of older adults at risk for COVID-19 or recovering from this disease, especially those with long COVID manifestations who are frail or may become frail are strongly indicated.

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.

The connection between the nurse employee’s apparent degree of work environment incivility and their expectation to stop their individual associations has been upheld by research for far over 10 years. Placed contentions have additionally analyzed a distinction in nurses' view of work environment incivility considering the kind of working environment (i.e., regardless of whether a public or private healthcare practice), considering the impression of existing working environment incivility and aim to stop employment, separately. The reason for such survey of writings is not just to decide the degree to which work environment incivility influences a nurses' plan to stop employment, yet more so to make for all viewpoints being additionally featured. Additional exploration on working environment incivility, remains continuous, with its related contributory elements, and the impacts on the examined relationships. New research on working environment incivility has critical ramifications for nurses, patients, healthcare services and associations were generally investigated 14569151718232427282943445868697172. Work environment incivility displays lack of respect, negligence or discourteousness that has formed into a combined issue, proved by irritating unfavorable consequences for human resources, and the adverse consequence on the association 78.

Background Many older adults are vulnerable to becoming frail. They are also often at risk for falling and serious injuries and poor health outcomes. Aim This exploratory review examines the correlates of frailty, and fear of falling and their association insofar as older adults wellbeing may be jeopardized. Methods and Procedures Articles extracted from major electronic data bases that addressed the current topic of interest were used. Key findings regarding the syndromes of frailty and fear of falling were duly downloaded, analyzed and summarized in narrative form. Results A high proportion of older adults can be expected to exhibit frailty or become frail as they age. Many too are at risk for falls and fear of future falls, regardless of frailty status. A persistent fear of falls may however, heighten frailty risk or manifestations if not duly addressed in a timely manner. Conclusion Prompt comprehensive assessment of at risk older adults, as well as the frail and pre frail older adult, plus those who have fallen may avert serious injury and long term disability plus excess frailty and its deleterious impacts this syndrome has on aging older adults as well as societies.

Copper (Cu) has a strong impact on the function of the immune system through several different pathways. These impacts include helping the function of monocytes, neutrophils, and macrophages, and enhancing Natural Killer cells’ activities. Cu also has a role in antimicrobial properties and inflammatory response. It is also important for IL-2 production and response, which is a component of adaptive immune cells. Additionally, Cu has multiple roles in both proliferation and differentiation of T cells and is involved in the production of antibodies. Cu deficiency can even lead to "increased viral virulence"1. Copper has a long history of use in medicine, and has continued to be used for purification of water, including use in hospitals to prevent legionnaires disease. The CDC pre released information on a study completed in March 2020 on the lifespan of COVID-19 on different surfaces which included its lifespan on copper, where it was completely dead within 4 hours. In addition, "Several reports demonstrated that Cu deficiency weakens the human immune response" 2. Given the multiple avenues of impact, it has been suggested that Cu supplementation, within recommended levels, be given to individuals who are low in Cu to help them fight off COVID-19. It is also possible that Cu supplementation, within recommended levels, may help prevent COVID-19 infection, or help individuals who are not low in Cu to fight off COVID-19 infection. However, dosage would have to be carefully managed, as excess levels of Cu can lead to both neurodegenerative and neurodevelopmental diseases.

Background Aging is said to represent a declining state that is possibly especially compromised by sleep issues, and declining melatonin levels. Aim This review examined the idea that aging can be favorably influenced in numerous ways by the addition or maintenance of adequate melatonin levels. Specifically, the impact of melatonin on skeletal muscle was the key topic of interest. Method Reviewed were peer reviewed research and review articles specifically pertaining to healthy aging, melatonin, and muscle associated observations. Results Declining melatonin levels greatly impact multiple essential body systems and tissues. Supplements or interventions that heighten melatonin presence appear to have beneficial impacts on aging in general, and muscle function and structure, in particular. Conclusion The use of melatonin early on in the aging process is likely to produce more favorable long-term outcomes than not in cases of deficiency, and should be further investigated.

Background Aging, a commonly accepted time period of declining heath has been shown to vary in terms of its impact on function and independence. Aims This mini review examines the current impact of COVID-19 on the goal of ‘successful aging’, a conceptual model and outcome variable deemed desirable, but hard to attain. Methods Peer reviewed articles published between March 1 2020 and April 15 2021 focusing on ‘successful aging’ and COVID-19 secondary impacts, as located in the PUBMED data base were specifically sought. Results Despite a lack of consensus on the concept of ‘successful aging, and whether this can be achieved or not, ample evidence points to a severe secondary impact on efforts to age as successfully as possible by older adults, especially those isolated in the community as a result of lockdowns. Conclusion Pursuing more efforts to counter predictable harmful cognitive as well as physical impacts of lockdowns, resource and movement restrictions is urgently needed.

Purpose This paper assess the impact of COVID-19 pandemic on Education, Staff development and Training in Africa. Online Research Methodology/Approach The data use in this paper was generated from online survey questionnaire, in which the participants were asked about certain questions in which covid-19 affect their social-economic situation. The questionnaire was design to help Africa to understand covid-19 impacts on their social and economic live. Results The results of this study reveal that coronavirus pandemic affected Africa in a number of ways; 1) 52.2 percent of the respondents said they should open school now in Africa, while 47.8 percent fear they should not open schools 2) 81 percent said before educational institution are closed there is public or official announcement that institutions must be closed due to pandemic—may be 3 months, ……,,…,, one week it depends on the severity of how covid-19 is spreading across the regions in Africa, 10.7 percent of the respondent said it may be and only 8.3 percent said it is not official announced.3) 65.4 percent of the respondents said government implemented an education response for continue of learning in Africa while educational institutions are closed 4) 61.5 percent said use of online/digital learning platform is the method for continuity of learning is currently available for children affected by closures of educational institutes provided by government, while 50 percent said television, radio, or podcast broadcast and 17.9 percent said assigning reading and exercises for home study. 5) 45.3 percent out of 100 percent said use of online or digital learning platform are the proportion of children affected by education institution closure. 38.7 percent said the proportion of children affect are the one that concentrate of using television, radio or podcast broadcasts to get academic content. 14.7 percent of the respondents are the proportion of the children affected by educational institute closure if they are assigning reading and exercises for home study. 6) 52.6 percent of the respondents from non-government organization, private schools said use of online or digital learning platform is the method for continuity of learning is currently available for children affected by closures of educational institutes, while 61.5 percent said use of online/digital learning platform is the method for continuity of learning is currently available for children affected by closures of educational institutes provided by government. The same thing government said as well. Similar respondents from government as do the non-government or private schools and 35.9 percent respondent said television, radio and podcast broadcast are method for continuity of learning is currently available for children affected by closures of educational institutes-provided by non-governmental organization, private schools etc, whereas 50 percent of the respondents said assigning reading and exercises for home study is the method for continuity of learning is currently available for children affected by closures of educational institutes-provided by government.7) 48.1 percent of the respondents said for the impact of covid-19 pandemic on staff development and training that their enterprise or organization partially suspended operation due to the pandemic and 34.2 percent of the responded said they completely suspended operation because of coronavirus pandemic and 16.5 percent said no closures on in operation for staff development and training because of pandemic. 8)According to the results of this question of the online survey, 49.3 percent said the challenges their enterprise face in delivery staff training programmes and activities using online learning or offline learning during covid-19 was due to infrastructure issues such the problem associated with internet and the like. The survey of the study also confirmed that 32.9 percent twice said limited digital skills of trainers and cost of staff training was a major setback to train staff in their enterprise or organization or department or establishment while 30.1 percent said it is due to limited digital literacy of users are the main challenges face by their department in order to train staff. Policy Implications The implication of the results from this online survey is that it has serious impacts on education closure and staff development and training. As educations are closed due to covid-19 pandemic, it will affect already problems of human capital that are hampering the development of Africa. Due to covid-19 pandemic, the achievement of sustainable development goals on quality education will be seriously halted. The government and the ministry in Africa should work hand in hand to solve the problems of children affected by schools closure after the pandemic by either additional hours or provide more study hours for schools to catch-up with what happened during the pandemic, the study noted. Originality/value The impact of covid-19 on education, staff development and training.

For economic growth and development in any WE African country the GDP progress is depending on the key push-pull factors as migration, personal remittances received, bilateral aids and, absolutely, employment in agriculture which is about 1/3 of the population and not a predominant and protected minority as happens in the industrialized EU and North America. In order to represent the framework of the reciprocal dependencies the present study used the statistics of Gambia from WDI covering the periods from 1960 to 2017 by applying linear regression models. The results confirmed that migration and remittances have significant positive impact on employment in agriculture because new investment in agriculture created new skilled and unskilled employment. The results also found out that employment in agriculture has negative and significant impacts on foreign aids: 10% increase in migration, increases foreign aid by 50.3%. Increasing 10% of remittance, increase economic growth by 0.14% but 10% increases in employment in agriculture, decrease economic growth by 0.04%. To face globalization the economy of the Gambia should use the foreign aid to improve agriculture production and productivity thereby increase economic growth through human capital theory of migration, skilled migration, export and food security, the study recommends.

A cross-sectional study was conducted from November 2017 to March 2018 to determine the prevalence of ovine fasciolosis in the Community Based Horro Sheep Breeding site at Horro district, Horro Guduru Wollega zone, Ethiopia. Coprological examination was performed on a total of 390 sheep at the study area. Age, sex, body condition score and peasant association were taken into consideration as rik factors. An overall prevalence of fasciolosis 45.4% 95% CI (40.41 50.36 was found on the basis of coprological examinations. The prevalence of fasciolosis findings according to PAs were (41.5%) in Laku Ingu and (48.2%) in Gitilo Dole. Statistical analysis of the prevalence among study site (PAs) showed insignificant difference P=0.102 (P>0.05), but significant difference (P<0.05) was observed between animal age groups (P=0.032, with a prevalence of 37.2% in young and 49.8% in adult) and body condition scores (P=0.001, with a prevalence of 57.9%, 43.5% and 29.9% in sheep with poor, medium and good body condition score, respectively. There was insignificance difference (P>0.05) in sex group of study animals in which the prevalence was 47.6% in female and 38.8% in male. Therefore further studies on the epidemiology, seasonal dynamic of the disease, the snail intermediate host and impacts of the infection in animal production with implementations of strategic intervention is necessary.

Since the independence of South Sudan, Sudan lost 75% of its oil reserves, this led to major fuel shortages country wide, the fuel shortage raised the fuel prices and the overall transport prices. Scarcity led to black market trade of fuel specially in states away from the Capital City (Khartoum). Managing the available stock comes first before increasing the supply amount in order to solve the problem, one of the major fuel consumers to be managed is the transport sector specially the long haulage freight transport. Moving freight in Sudan is constrained by inadequate infrastructure and high costs. This paper covers specifically the long haulage freight transport between Khartoum State and Western side of the country (Darfur Region), Contributing to manage fuel consumption for trucks, taking into account trucks types used, roads, environmental impacts and mitigation measures applicable to save fuel . The results showed that the primary reason for the excessive fuel consumption is the usage of the rigid trucks (lorries) for transport specially the Hino700 series, this truck type, overload and absence of weight stations and control policies contributed significantly to deterioration of roads and transport efficiency decreasing. First step towards the solution would be in upgrading roads infrastructure assuring high quality along with enforced weight regulations and weight stations to protect roads from damages. High quality roads shall ease the usage of different truck types with different configurations. Then stablish a policy to force replacement of the low efficiency lorry truck types with high quality tractor semi-trailer combinations.

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.

The effects of global warming have been causing irreversible damage to the Earth over the past decades. One way we can reduce our individual impact on the environment is to focus on the production and consumption of Eco‐friendly sources of electricity such as solar, wind, or bio-electric energy. Based on the current available and suitable energy options, we have proposed to modify a chosen house from Northern Wisconsin by using a hybrid system including solar energy and wind turbine energy to replace the traditional power grid. Considering sunlight‐time, wind speed in Northern Wisconsin, we have predicted the immediate and long‐term fiscal and environmental impacts. From this cost‐benefit analysis, we project that the best hybrid option is a combination of 95% solar power and 5% wind energy, which would save about $41,000 over the next 30 years.

This study explores the effects of the collaborative model of health impact assessment (HIA), as deployed in Monteregie (Quebec), on the development, adoption and implementation of municipal projects that include health considerations. Nine HIA processes were studied in nine territories and 35 individuals were interviewed. Data collection was based on the six steps of contribution analysis, and included document analysis, semi-structured interviews, and on-site observations. The study design is cross-sectional design were every HIA was analysed at least six month after completion. The individuals interviewed where those implicated into the HIA process (no matter at what point of the process). No exclusion criteria were applied considering that all points of view were important for this analysis. The Contribution Analysis (CA) was used to analyze the data. The study results emerged form by the interviews, the field observations and document analysis. They showed that the HIAs had varying results. First, the actors involved acquired new knowledge. However, the HIAs had little impact in terms of increasing the municipal actors’ awareness of health issues. Rather, it helped them acquire arguments for raising awareness among and convincing their municipal council members of the merits of certain actions and their potential positive impacts on citizens’ health. In fact, the HIAs were generally undertaken by municipal actors already aware of the importance of promoting citizen health. Second, as observed in the document, in a few of the HIAs, some recommendations were integrated into planning documents, but usually, as reported by the actor, the HIA report constituted an additional planning document and was not merged with the original planning documents. Lastly, following the HIAs, document analysis and interviews showed that most of the municipal actors continued to include health considerations in their subsequent planning of public policies and projects. Prerequisites for effective HIA include the presence of municipal actors, who are aware of the importance of their role in their local population’s health, municipal policies that include health considerations, and the municipality’s active participation in the HIA process. This study sheds light on the complexity of the factors that ensure HIA impact on municipal decision making and decisions. The particularities of each HIA process play a major role.

In The Gambia like all nations, drug abuse is seen as a social and health problem that has many serious implications for the physical, social, psychological and intellectual development of the victims more especially, the children. Therefore, it continues to be a concern to families, community leaders, educators, social workers, health care professionals, academics, government and its development partners. Though there are some studies on drug abuse, there is none on children and drug abuse focusing on the street children the most vulnerable category. Street children are hypothesized to be more at risk of any epidemic including drug abuse. This study sought to determine the risk and prevalence of drug abuse among street children focusing on those in the car parks. The research was focused on six critical areas: level of knowledge of drug abuse, perception towards it, level of knowledge of the causes of it in the community and among street children, level of knowledge of negative impacts of it, level of knowledge of the preventive methods; and level of knowledge of the support services and treatments needed by victims. A structured questionnaire was used to collect the data from thirty five participants (i.e. one driver and six casual apprentices from each of the five car parks) were interviewed. The data was presented and analyzed using tables and percentage. The findings revealed among other things, that there is high level of awareness of drug abuse but the feelings towards it are mixed. Like other children, street children are abusing drugs mainly due to peer influence with the ultimate objective of getting high to relief stress, group recognition, desire to be trusted by peers, etc. Similarly, participants are highly aware of the negative impacts encompassing fighting, stealing, mental illness, etc. To finance the behavior, victims are engaged in all types of dangerous antisocial behavior including romantic ones exposing them to a range of diseases including STIs and HIV/AIDS. Marijuana is the most commonly abused drug. Though in the minority, some have started experimenting cocaine/coke, hashish; and heroin. While participants have good knowledge of the critical methods to fight drug abuse, the support services needed by victims, victims are mostly reluctant to seek the services not only because they are hard to find but fear societal stigmatization, exclusion and discrimination and professionals’ maltreatments.

All aspects of life activities in living cells are mediated/executed and regulated by a vast number of networks, comprising a wide spectrum of components, starting with simple biomolecules and ending with the whole organism, and functioning within a precisely organized tight framework. Proper mediation of cellular activities necessitates their inclusion within the context of structured and organized network systems capable of regulating/coordinating and synchronizing the countless numbers of biological processes occurring within living cells. The number of biological networks and pathways within the living cell is considerably huge, being dependent on the structural complexity and functional capabilities of the cell. Pathogenesis and progression of human diseases result from functional disturbances of biological networks within the cell as disturbed network function leads to deleterious effects on physiological processes dependent on, and mediated by, affected network(s). Ensuing pathological processes, defined by the nature of disturbed networks and the specific organs or tissues affected, pave the way for the development of pathognomonic and characteristic disease entities. As most network functions are dependent on relatively small number of key regulatory biomolecules, i.e. enzymes/proteins and signal transducing factors, it follows that functional disturbances of biological networks and pathogenesis of disease states can be attributed, in most instances, to quantitative and/or qualitative abnormalities of these key regulatory molecules. Study and analysis of the structural designs and the functional mechanisms of biological networks would have crucial and important impacts on many theoretical and applied aspects of biology, in general, and of medical sciences in particular. Meticulous study of biological networks represents an important and integral aspect in study of biology. Interpretation and analysis of key information deduced from observing and analyzing structural designs and functional characteristics and dynamics of biological networks discloses and defines the basic framework within which life activities in living cells are initiated, adapted to physiological requirements, maintained, and terminated upon completion of their aims. More important, however, is the contribution of this information to proper understanding of the different mechanisms responsible for regulating and synchronizing the functions and performances of the vast spectrum of different network categories within the cell. In addition to its vital scientific significance, discovering and defining the key pivotal structural and regulatory molecules within life-mediating networks, and along different pathways responsible for controlling functional dynamics of the network, represent an indispensable diagnostic approach insistent for designing proper therapeutic approaches to diseases caused by network defects.

Background: Monitoring ultrasonic probe quality remains an important problem which impacts diagnostic accuracy. Here we present a quantitative method to assess probe quality primarily based on measuring probe maximum contrast (dB) and dynamic range. Method: Contrast relevant parameters of 26 transducer models manufactured by five manufacturers were measured with a novel Random Void Phantom (RVP) approach. 3D-data were acquired and analysed to determine image quality. Results: Acoustic contrast values ranging from 15dB to 36dB were observed. Conclusion: By examining artefact producing side lobes, the novel RVP approach presented here permits a quantitative assessment of ultrasound probe quality.

Overview: Dementia is a serious brain disease that impacts negatively in several areas of patient’s functioning. Depression has a strong link with dementia and is part of the behavior and psychological symptoms (BPSD). Behavior management for depression is recommended as a first-line psychological treatment for dementia patients. However, there are no systematic reviews examining the efficacy of behavior management for depression in dementia. Objective: To examine the efficacy of behavior management (BM) for depression in dementia patients. Methods: Five electronic databases were searched (1999 to 2015) for randomized controlled trials (RCTs) which were selected according to eligibility criteria. Data was pooled, quality assessment was completed, and a meta-analysis was performed. Results: This review included ten randomized controlled trials. In the four studies where behavior management was a focused intervention, no significant treatment effect was observed (standardized mean difference SMD -0.20; 95 % CI -0.96 to 0.56). In the remaining six studies in which behavior treatment was involved as a component, the analysis showed a trend favored the intervention, but it was not significant (SMD -0.12; 95 % CI -0.25 to 0.01). Conclusion: There is no evidence for behavior management alleviating depression in dementia patients. Future research examining the efficacy of specific behavior management techniques for milder forms of dementia and multimodal interventions are recommended.

Background: The impact of sexual violence in any community is extremely devastating and women in the Eastern part of the Congo are no exception. Sexual violence not only affects the health of women, but it impacts their social life within the community too. Objective: The study aims to investigate the experiences of female victims of sexual violence in accessing medical care in North Kivu. Design: An interpretive, phenomenological approach was used for this inductive and qualitative study. In-depth informant interviews were the main data collection tool. Open-ended questions were used during the interviews in order to garner more information from the interviewees. Heidegger’s approach was utilized in analyzing the collected data. Results: The analyzed and interpreted results of the data indicated that survivors of sexual violence are engaged in an ongoing struggle. The victims demonstrated immense resilience despite the lack of comprehensive medical care and have continued to reassemble their broken lives. In order to present the outcomes of the research in a succinct and coherent manner, the outcomes are categorized into five sub-themes: managing worries and shame; regaining happiness; healing and restoration; the need for professional assistance and struggles in daily life. Conclusion: The study provides an understanding of the recovery processes of survivors of sexual violence in North Kivu, with important insights into dimensions that rehabilitation programs should take into consideration.

Up till now, chitosan has confirmed its versatile application in skin, cartilage and bone tissue engineering, as well as in drug delivery applications. This study is focused on enzymatic degradation of porous chitosan structures usually designed for mentioned purposes. In vitro degradation was monitored during four weeks of incubation at physiological temperature and in two different media, phosphate buffer saline solution and water. The scaffolds were characterised before and after enzymatic degradation using scanning electron microscopy and infrared spectroscopy with Fourier transformations (FTIR). According to the gravimetric analysis, higher weight loss of chitosan scaffolds was observed in buffered medium with respect to the water. The results implied that the total weight loss obtained in buffer involves physical dissolution of chitosan and lysozyme cleavage of glycoside bond. Importantly, FTIR identification of chitosan scaffolds after enzymatic degradation indicated the absence of lysozyme activity in water, indicating that weight loss is a result of the chitosan dissolution. This finding greatly impacts design of degradation experiments and characterisation of degradation behaviour of chitosan-based materials utilised as implants or drug delivery systems.

Neo-Darwinian natural selection theory indicates that sudden, drastic changes in the environment place selective pressure on genetic variants in a population. As time progresses, this pressure sculpts individuals to better fit this new environment. Waddington’s classic experiment was repeated using white-eyed (the w1118strains) flies which produced the crossveinless (cve; disturbed wing crossveins) trait from the parent generation. The F1 generation was split into two selection lines: an Upward Selection Line, that produced more cve in successive generations, and a Downward Selection Line that responded with a consistent but non-linear decline in the percentage of crossveinless. This article will introduce and enlarge observations made on flies with cve; especially the manner in which the Waddington experiment impacts the population. It seems that Waddington evaluated crossveinless just by what it is good for, but not by the price of using it. That is to say, there is an inevitable cost that needs to be paid in order to acquire crossveinless-ness (cve and the associated phenotypes).

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 objective of this study was to investigate whether percentage of mature oocytes retrieved from ovaries stimulated with long agonist or multi-dose antagonist protocols affect the implantation, clinical pregnancy and live birth of ICSI (Intracytoplasmic sperm injection) cycles. The 654 cycles of agonist (long lupron) and 610 cycles of multi-dose flexible antagonist (antagon) were analyzed after stratification according to the percentage of the mature oocytes retrieved. The clinical pregnancy of the groups with less than 30 % mature oocytes retrieved, both antagonist and agonist protocol was statistically lower (at least p< 0.05) compared to the groups with more than 30% mature oocytes retrieved. In the agonist protocol, the implantation and live births for this group were significantly (p<0.009) lower than in the group with ≥70% mature oocytes retrieved. The live births in groups with more mature oocytes retrieved (30-69% and ≥70 %) of the antagonist protocol were lower (22.2% vs. 35.9% and 23.9% vs. 41.5%, p<0.0001, respectively) compare to the agonist protocol. The results of our study showed that a very low percentage of mature oocytes retrieved impacts the clinical outcome of antagonist and long agonist protocols.

Given the aging of the population, an increase in the number of persons in need of long-term care and end-of-life care can be expected in the coming years. The scientific literature underlines the lack of end-of-life care for elderly people in long-term care centres. The aim of this study is to explore needs in terms of new knowledge and research on end-of-life care for elderly persons in long-term care settings, from the perspective not only of the scientific and international community, but also of Quebec professionals concerned by the issue. An online survey using the LimeSurvey® tool was conducted in 2015 among health professionals involved in end-of-life care for elderly persons in long-term care settings in Quebec. 208 professionals rated the priority of new knowledge and research needs related to 1) health professionals; 2) delivery and quality of care; 3) residents and their loved ones; and 4) organization and management of care. The results show that the statements collected in scientific literature resonate with health professionals. The most important need is to identify the symptoms of distress in residents in the final stages of their lives, as well as their causes and treatments. This study also shows professionals’ concerns about attitudes, beliefs, and values of practitioners and the related impacts on end-of-life care in long-term care settings. This study shows that there is a significant need for new knowledge and research. It revealed that there are few studies on end-of-life care for elderly persons in long-term care settings and that there is much more to be discovered in this field.

Although structured taught aquatic baby programmes (STABPs) are one of the earliest forms of physical activity, the possible impacts of structured taught aquatic baby programmes are unknown. This study aims to understand the perceived impact that attending STABPs has on parents/carers, their baby/child and their family. An online survey was completed by 2854 parents/carers. It was advertised via numerous online advertisements. Of the respondents, 89% had attended STABPs. ‘Attendees’ were significantly older and were less likely to live in a more deprived area compared to ‘non-attendees’. STABPs are perceived to be beneficial in terms of water safety, confidence, benefits to parent-child relationships and interaction with other children but cost affects attendance. The evidence-base regarding the benefits of STABPs should be established to further understand their impact on parents/carers and babies. Further research should focus on understanding barriers to attendance and ways to facilitate attendance. The need to understand the ‘key ingredients’ of structured taught aquatic baby programmes was highlighted.

The prevalence of young adults endorsing depressive symptomatology is thought to peak during late adolescence. While there has been a wealth of research assessing the relationship between decline of the prefrontal cortex and how this process impacts depression and therapy in older adults, very little is known about the relationship on the younger end of the continuum. The current study sought to explore whether there is also a significant relationship between executive functioning and depression in younger adults. In addition, different types of executive dysfunction were assessed to better understand the possible implications for therapy in younger adults with depressive symptomatology. Data from 1,730 college-aged participants were collected on measures of depression (Center for Epidemiological Studies-Depression, CES-D) and executive dysfunction (Dysexecutive Questionnaire, DEX). In addition, three factors of the DEX were assessed; Executive cognition (EC), emotional/ behavioral control (EMO), and metacognition (MC). Correlations between CES-D scores and the full DEX survey were statistically significant (R = .45, p < .001) as were correlations between CES-D scores and scores on each individual factor (p< .001). A multiple linear regression was run to demonstrate the predictive value of each individual DEX factor as a function of CES-D scores (p < .001). Results suggested that there was a clear relationship between depressive symptoms and executive dysfunction and that all factors of the DEX appeared to be affected by depressive symptoms in this population. The implications of these results for therapy, particularly the use of problem-solving therapy or complimentary executive functioning training are discussed.

Introduction Working with people who are HIV positive is a herculean task and relevant theories to assist them medically, psychologically, economically, socially and otherwise are necessary. People who are living positively with HIV and AIDS are usually ridiculed, discriminated against, rejected and isolated. Using theories to work with them will help to cushion the negative impacts of HIV and AIDS, especially stigma which has been identified as a major barrier to health care and quality of life in illness management. The fundamental human rights of people living positively with HIV and AIDS should be protected since majority of such rights are usually trampled upon. The review aimed at discussing the potential benefits of using theories to assist people living positively with HIV and AIDS to cope with their various and varying situations in life. Materials and Method: Information for this study was collected by extensive review of recent literature on theories for assisting people living positively with HIV and AIDS. The paper reviews theories that influence long-term behaviour change among people living positively with HIV and AIDS. It assesses the need for using these theories to improve HIV and AIDS intervention in developing countries including Nigeria. In this study, eleven behaviour theories were reviewed. Result It was noted that some of the theories promoted adherence as well as helped to explain the benefits of adherence to HIV and AIDS medication. Also a good number of the theories assisted researchers in designing effective intervention strategies. Conclusion: Further research is needed to determine the effective theories that will increase adherence to long-term treatment regimens of HIV and AIDS. Such theories can be used to alleviate the potential burnout of Caregivers and people living positively with HIV and AIDS who travel long distances for diagnostic procedures and work long hours without adequate remuneration, support and supervision.

Despite recent improvements in teen pregnancy and birth rates, 2000 teens get pregnant each day in the U.S. Innovative strategies that are effective and acceptable within communities are needed to continue these declines in teen pregnancies. Captivating educational interventions enhanced by infant simulators, such as “Baby Think it Over” (BTIO), can discourage teen pregnancy. The purpose of this research was to evaluate a BTIO intervention to determine the effectiveness of the program in changing 236 high school students’ perceptions of the costs of teen parenting. From a comparison of pre-test/two post-test measures, it appears the participants recognized that teen parenting would be costly in terms of increased difficulty in making responsible decisions as well as the challenges of juggling school with parenting. They also recognized other costs including negative impacts on relationships, on feelings of personal worth, and the likelihood of diminished achievements in the future.
