This report investigates the impact of potential misclassification of samples on HIV prevalence estimates for 23 surveys conducted from 2010-2014. In addition to visual inspection of laboratory results, we examined how accounting for potential misclassification of HIV status through Bayesian latent ...class models affected the prevalence estimates. Two types of Bayesian models were specified: a model that only uses the individual dichotomous test results and a continuous model that uses the quantitative information of the EIA (i.e., the signal-to-cutoff values). Overall, we found that adjusted prevalence estimates matched the surveys’ original results, with overlapping uncertainty intervals. This suggested that misclassification of HIV status should not affect the prevalence estimates in most surveys. However, our analyses suggested that two surveys may be problematic. The prevalence could have been overestimated in the Uganda AIDS Indicator Survey 2011 and the Zambia Demographic and Health Survey 2013-14, although the magnitude of overestimation remains difficult to ascertain. Interpreting results from the Uganda survey is difficult because of the lack of internal quality control and potential violation of the multivariate normality assumption of the continuous Bayesian latent class model. In conclusion, despite the limitations of our latent class models, our analyses suggest that prevalence estimates from most of the surveys reviewed are not affected by sample misclassification.

Cholera is an acute gastrointestinal infection caused by the bacterium Vibrio Cholerae serogroup O1 or O139, and is often linked to unsafe drinking water, lack of proper sanitation and personal hygiene. It adversely affects mostly the poor and vulnerable populations in countries, which are already d...eprived of proper health facilities and conducive environmental conditions. The disease spreads through oro-fecal transmission by the ingestion of contaminated food or water or by person-to-person contact. It has a short incubation period of 2 hours to 5 days and the number of affected cases can rapidly increase across large regions. Cholera is a significant threat to global public health leading to an estimated 3-5 million cases per year worldwide, with an annual toll of 100,000 deaths. The disease was first reported in 1817 from the Ganges Delta of India and since then the ongoing 7th pandemic has emerged from Indonesia, reached Africa in 1970 and Somalia happens to be one of the early affected countries. Over the past few decades,
Somalia has witnessed the occurrence of repeated AWD/Cholera disease outbreaks that have caused high morbidity and mortality across the country.

Plastic pollution is ubiquitous throughout the marine environment, yet estimates of the global abundance and weight of floating plastics have lacked data, particularly from the Southern Hemisphere and remote regions. Here we re...port an estimate of the total number of plastic particles and their weight floating in the world's oceans from 24 expeditions (2007–2013) across all five sub-tropical gyres, costal Australia, Bay of Bengal and the Mediterranean Sea conducting surface net tows (N = 680) and visual survey transects of large plastic debris (N = 891). Using an oceanographic model of floating debris dispersal calibrated by our data, and correcting for wind-driven vertical mixing, we estimate a minimum of 5.25 trillion particles weighing 268,940 tons. When comparing between four size classes, two microplastic <4.75 mm and meso- and macroplastic >4.75 mm, a tremendous loss of microplastics is observed from the sea surface compared to expected rates of fragmentation, suggesting there are mechanisms at play that remove <4.75 mm plastic particles from the ocean surface.

The WHO guidelines for malaria bring together the Organization’s most up-to-date recommendations for malaria in one user-friendly and easy-to-navigate online platform.
The WHO guidelines for malaria bring together the Organization’s most up-to-date recommendations for malaria in one user-frie...ndly and easy-to-navigate online platform. The Guidelines supersedes 2 previous WHO publications: the Guidelines for the treatment of malaria, third edition and the Guidelines for malaria vector control. Recommendations on malaria will continue to be reviewed and, where appropriate, updated based on the latest available evidence. Any updated recommendations will always display the date of the most recent revision in the MAGICapp platform. With each update, a new PDF version of the consolidated guidelines will also be available for download on the WHO website.
This version of the Guidelines includes an updated recommendation for malaria vaccines, new recommendations on the use of near-patients qualitative and semiquantitative G6PD tests to guide anti-relapse treatment of P. vivax and P. ovale, updated recommendations on primaquine and the recommendation on the use of tafenoquine. It replaces the versions published on 16 February 2021, 13 July 2021, 18 February 2022, 31 March 2022, 3 June 2022, 25 November 2022, 14 March 2023 and 16 October 2023.

Results: Twenty-one studies were analyzed, most of them demonstrating an association between the existence of burnout and the worsening of patient safety. High levels of burnout is more common among physicians and nurses, and it is associated wit...h external factors such as: high workload, long journeys, and ineffective interpersonal relationships. Good patient safety practices are influenced by organized workflows that generate autonomy for health professionals. Through meta-analysis, we found a relationship between the development of burnout and patient safety actions with a probability of superiority of 66.4%. Conclusion: There is a relationship between high levels of burnout and worsening patient safety.

For the estimated 20 million refugees and 25 million internally displaced people worldwide, well-planned settlements can help to maximise their protection and security, and support them to minimise the spread of disease, manage natural resources sustainably, and maintain good relations with their ho...sts until durable solutions to their displacement are achieved.
The result of extensive consultations with a wide range of specialist organisations, this book takes a holistic view of shelter for displaced populations, extending beyond refugee camps to consider support for all of the settlement and shelter options open to displaced people. It offers co-ordinators and specialists a common planning tool which links strategy, programmes, projects, and technical information for use in the field

Applying the evidence of what works from HIV-related stigma and discrimination in six settings to the COVID-19 response
This brief provide evidence-informed guidance to countries on the intersection of stigma related to HIV and COVID-19 in national responses.
Food security, human health and wellbeing largely depend on biodiversity. Biodiversity supports agriculture through ecosystem services such as pollination and water purification, and provides access to natural medicines,
which are the primary source of health care for 4 billion people worldwide

Представлены данные о факторах риска, которые способствуют развитию суицидального поведения. На развитие суицидального поведения влияет целый ряд факторов: пол, ...озраст, место проживания, профессия, семейное положение, состояние здоровья и т.д. Отмечается влияние экономических и социальных факторов на уровень суицидальной активности населения. Наблюдаются взаимосвязи между психическими расстройствами, наркологическими заболеваниями (особенно алкоголизм) и суицидом. При наличии многочисленных исследований в области суицидологии целый ряд проблем остаётся неразрешенным. Необходимо их дальнейшее изучение. Особо следует отметить значимость «региональных» факторов риска, которые оказывают наибольшее влияние на формирование суицидального поведения в отдельно взятом регионе.
