HIV testing programmes need to ensure that all clients who test for HIV are provided with correct diagnoses. The accuracy of HIV testing is critical to prevent misdiagnosis, as the consequences of giving an incorrect test result can be serious for clients, HIV testing services, HIV programmes and pu...blic health.
With the evolution of global HIV epidemiology, HIV testing approaches must also evolve to maintain accuracy and efficiency in population-level diagnosis. Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used. As a result of changing epidemiology and declining HIV positivity in testing, WHO recommends all countries use a standard three-test strategy to ensure a PPV of at least 99%, minimizing false-positive misdiagnosis. The WHO-recommended HIV testing strategy, along with quality assurance measures such as retesting to verify a positive diagnosis prior to initiation of HIV treatment, is cost-effective as it prevents misdiagnosis and unnecessary initiation of costly lifelong treatment.
This implementation guide provides practical advice on switching to a three-test strategy and instituting other measures that can help national HIV programmes deliver high-quality, accurate HIV testing services and ensure that misdiagnosis is minimized.

The present Community Empowerment Manual draws upon the lessons learned of the Community Protection Approach implementation in Lebanon, the occupied Palestinian territory and Central America during the period 2015-2020 by WeWorld – GVC and its partners.
The Manual means to accompany Field Staff i...n devising the most appropriate strategy to engage with communities, given the conditions of access, security and time of the specific context in which a project is implemented. Even though the steps described proceed alongside the implementation of the Community Protection Approach, the manual has different sections providing guidance for the definition of engagement strategies in any context or project in question.

The Capacity Project worked to strengthen HRIS in several low-resource countries to assist decision-makers and human resources managers in identifying and responding to critical gaps in HRH. The findings and recommendations in this report cover the Capacity Project’s implementation of HRIS in Swaz...iland, Rwanda and Uganda.

Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they ha...ve primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models to spatially interpolate the observations. Our estimates show that the accumulated number of microplastic particles in 2014 ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons, which is only approximately 1% of global plastic waste estimated to enter the ocean in the year 2010. These estimates are larger than previous global estimates, but vary widely because the scarcity of data in most of the world ocean, differences in model formulations, and fundamental knowledge gaps in the sources, transformations and fates of microplastics in the ocean.

This codebook outlines the set of TUFF procedures that have been developed, tested, refined, and implemented by AidData staff and affiliated faculty at the College of William & Mary. We initially employed these methods to achieve a specific objective: documenting the known universe of officially fin...anced Chinese projects in Africa (Strange et al. 2013, 2017). We have since then employed these methods to track Chinese official finance to five major world regions: Africa, the Middle East, Asia and the Pacific, Latin America and the Caribbean, and Central and Eastern Europe (Dreher et al. 2017). Additionally, other social scientists have adapted and applied the TUFF methodology to identify grants and loans from Gulf Cooperation Council (GCC) members (Minor et al. 2014), under-reported humanitarian assistance flows from traditional and non-traditional sources (Ghose 2017), foreign direct investment from Western and non-Western sources (Bunte et al. 2017), and pre-2000 foreign aid flows from China (Morgan and Zheng 2017). However, this codebook focuses specifically on TUFF data collection and quality assurance procedures to track Chinese official finance between 2000 and 2014.

Diabetes is a serious, chronic disease that occurs either when the pancreas does not produce enough insulin (a hormone that regulates blood sugar, or glucose), or when the body cannot effectively use the insulin it produces. Diabetes is an important public health problem, one of four priority noncom...municable diseases (NCDs) targeted for action by world leaders. Both the number of cases and the prevalence of diabetes have been steadily increasing over the past few decades

The aim of this study was to examine the prevalence of mental health symptoms (anxiety, depression, and stress) in Bangladesh and the factors associated with these symptoms during the COVID-19 pandemic.
They found that ...about 64%, 87%, and 61% of the respondents in Bangladesh reported high levels of depression, anxiety, and stress, respectively and this varied between divisions (regions), more in women, those who self-quarantined, and those that experienced classical symptoms of COVID-19. We think there is a need for mental health support in this population to minimise the long term effects.

This report, written in partnership with various Royal Medical Colleges and Public Health England, sets out the essential actions to improve the physical health of adults with severe mental illness (SMI) across the NHS. The report makes practical recommendations for changes that will help adults wit...h SMI to receive the same standards of physical healthcare as the general population and reduce the risk of premature death.

The magnitude and complexity of these mental health conditions caused by prolonged and extensive trauma requires a diagnosis fitting the unique context of the Syrian conflict. Over half a million people have been killed since the beginning of the conflict in 2011, and more than 6.4 million are inter...nally displaced with over 5 million living as refugees. SAMS documents the multi-dimensional nature of mental health disorders afflicting Syrians, including accounts of refugee experiences from Eastern Ghouta, Idlib, and beyond. This qualitative report seeks to raise awareness about increasing mental health needs, while sharing personal stories of those who have been affected by the trauma of the conflict.
