The salinization process at the mouth of the São Francisco River has been caused serious damage to the ecosystem and the quality of life among riverine populations. This study aimed to assess the perception of the riverine populations regarding the effects of water salinization at the mouth of the São Francisco River, and also to analyze the quality of water that is provided to the Potengi community in Piaçabuçu, Alagoas, Brazil. For data collection, semi- tructured interviews were conducted with 22 riverine residents. The analyses of water samples were carried out at four places in the community, in which analyzes of pH, electrical conductivity, determination of salinity, and turbidity of the water were made. It was possible to identify, during the performance of this study, the inefficiency of the public authorities, both concerning the informative and mitigating actions, as the exposure of the population to high levels of sodium and turbid water, leading to changes in the parameters concerning data established by the World Health Organization (WHO). The results revealed that one of the samples analyzed presented a saline level 17 times higher than the limit established by the WHO, and a turbidity index was 15.6 times higher than the technical limit established. Therefore, these changes have affected the health of the community, directly compromising the use of water and the composition of the biota in the region.

Nitrate groundwater contamination is of major interest all over the world. This problem arises in agricultural regions across Morocco. An excess amount of nitrate causes a serious problem in urban water networks and human health. Because of these health risks, considerable attention has been paid to find effective treatment processes to reduce nitrate concentrations to safe levels. The World Health Organization has set an acceptable level for nitrate in drinking water at 50 mg/L. The aim of this study is to reduce the nitrate concentration from groundwater using two membrane processes: Electrodialysis (ED) and Nanofiltration (NF). Efficiencies of these two technologies are compared in respect to nitrate ions removal, cost process and final quality of water. The results of technologies show that, for electrodialysis standards level can be achieved for a demineralization rate of 15% and the physico-chemical quality of the produced water is satisfactory. For nanofiltration we obtain a nitrate removal of 90% but the produced water is very de-mineralized and must be remineralized.

Abstract Background Joint contractures, which affect activity, participation, and quality of life, are common complications of neurological conditions among elderly residents in long-term care facilities. This study examined the reliability and validity of the Chinese version of the PaArticular Scales in a population with joint contractures. Methods A cross-sectional study design was used. The sample included elderly residents older than 64 years with joint contractures in an important joint who had lived at one of 12 long-term care facilities in Taiwan for more than 6 months (N = 243). The Chinese version of the PaArticular Scales for joint contractures was generated from the English version through five stages: translation, review, back-translation, review by a panel of specialists, and a pretest. Test-retest reliability, internal consistency reliability, construct validity, and criterion validity were evaluated, and the results were compared with those for the World Health Organization Quality of Life scale and the World Health Organization Disability Assessment Schedule. Results The Chinese version of the PaArticular Scales had excellent reliability, with a Cronbach α coefficient of 0.975 (mean score, 28.98; standard deviation, 17.34). An exploratory factor analysis showed three factors and one factor with an eigenvalue > 1 that explained 75.176 and 62.83 % of the total variance in the Activity subscale and Participation subscale, respectively. The subscale-to-total scale correlation analysis showed Pearson correlation coefficients of 0.881 for the Activity subscale and 0.843 for the Participation subscale. Pearson’s product-moment correlation revealed that the correlation coefficient (r) between the Chinese version of the PaArticular Scales and the World Health Organization Disability Assessment Schedule was 0.770, whereas that for the World Health Organization Quality of Life scale was − 0.553; these values were interpreted as large coefficients. Conclusions The underlying theoretical model of the Chinese version of the PaArticular Scales functions well in Taiwan and has acceptable levels of reliability and validity. However, the Chinese version must be further tested for applicability and generalizability in future studies, preferably with a larger sample and in different clinical domains.

Abstract Background The global coronavirus disease 2019 (COVID-19) was announced as pandemic by the World Health Organization (WHO). With the increased number of infected and dead victims daily all over the world, it becomes necessary to stop or overcome its rapid spread. Main body Although the production of vaccine or even specified effective anti-virus may take about six months to a year, intravenous immunoglobulin (IVIg) may be clinically used as a safe treatment to save and improve the quality of life of patients with a variety of immunodeficiency diseases such as lymphocytopenia, which is a common clinical feature in COVID-19. Conclusion Through the current review, it was concluded that this passive immunization may promote the immunity to better fight against the virus, so the survival of the patients could be kept longer. The efficacy of immunotherapy with IVIg would be greater if the immune IgG antibodies were collected from convalescent plasma therapy.

Abstract Over the past 25 years, there has been significant progress in increasing the recognition of, resources for, and action on adolescent health, and adolescent sexual and reproductive health (ASRH) in particular. As with numerous other health areas, however, many of the projects that aim to improve ASRH are implemented without well-thought-out plans for evaluation. As a result, the lessons that projects learn as they encounter and address policy and programmatic challenges are often not extracted and placed in the public arena. In such cases, post-project evaluation (PPE) offers the possibility to generate learnings about what works (and does not work), to complement prospective studies of new or follow-on projects. To fill the gap in the literature and guidance on PPE, the World Health Organization developed The project has ended, but we can still learn from it! Practical guidance for conducting post-project evaluations of adolescent sexual and reproductive health projects. This article provides an overview of the guidance by outlining key methodological and contextual challenges in conducting PPE, as well as illustrative solutions for responding to them.

According to the World Health Organization (WHO), 71 million people were living with Hepatitis C virus (HCV) infection worldwide in 2015. Each year, about 399,000 HCV-infected people succumb to cirrhosis, hepatocellular carcinoma, and liver failure. Therefore, screening of HCV infection with simple, rapid, but highly sensitive and specific methods can help to curb the global burden on HCV healthcare. Apart from the determination of viral load/viral clearance, the identification of specific HCV genotype is also critical for successful treatment of hepatitis C. This critical review focuses on the technologies used for the detection, discrimination, and genotyping of HCV in clinical samples. This article also focuses on advantages and disadvantages of the reported methods used for HCV detection, quantification, and genotyping.

In 2016, the World Health Organization, through the Global Cooperation on Assistive Technology Initiative, issued the Priority Assistive Products List which is meant to be a guide to member states of the 50 assistive products needed for a basic health care and/or social welfare system; it is also a model from which nations can develop their national priority assistive products lists. The aim of this opinion paper is to share my views about the Priority Assistive Products List on the grounds that it makes no distinct mention of sexual assistive devices, yet research has indicated that sexuality is an area of great concern for persons with disabilities. In any case, sexuality forms a core part of being human, and it impacts on both the physical and mental well-being of all human beings. I conclude in part that, in its present format, the list perpetuates the myth that persons with disabilities are asexual beings who are innocent of sexual thoughts, feelings and experiences. The list also propagates the stereotype that sexuality is a sacred, private, bedroom matter that should be kept out of the public domain, to the detriment of the health and well-being of persons with disabilities.

The objectives of this study were to quantify the fresh water quality of Blue Nile River before processing, identify the pollutants, and to determine the most polluted areas, and their impacts on living organisms as well as the surrounding environment. Thus, random water samples were collected and analyzed at the laboratory of the Ministry of Irrigation and Water Resources, Ground water and Wadis Directorates - Khartoum. The outcomes were compared with the World Health Organization standardization. The results revealed variations in the concentration of the studied elements taken from the different locations. But, the results indicated that the water quality is good, and it is within the permissible water use. However, further study is recommended to include seasonal variation as well as the biological analysis.
