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.

Cryptococcal disease is one of the most common opportunistic infections among people living with advanced HIV disease and is a major contributor to severe illness, morbidity, and mortality, particularly in sub-Saharan Africa.
These guidelines update the recommendations that were first released i...n 2018 on diagnosing, preventing, and managing cryptococcal disease. In response to important new evidence that became available in 2021, these new guidelines strongly recommend a single high dose of liposomal amphotericin B as part of the preferred induction regimen for the treatment of cryptococcal meningitis in people living with HIV. This simplified regimen - a single high dose of liposomal amphotericin B paired with other standard medicines (flucytosine and fluconazole) - is as effective as the previous WHO standard of care, with the benefits of lower toxicity and fewer monitoring demands.
The objective of these guidelines is to provide updated, evidence-informed recommendations for treating adults, adolescents and children living with HIV who have cryptococcal disease. These guidelines are aimed at HIV programme managers, policymakers, national treatment advisory boards, implementing partners and health-care professionals providing care for people living with HIV in resource-limited settings with a high burden of cryptococcal disease.

The main objectives of these guidelines are to:
1. contribute to the quality assurance of medicinal plant materials used as the source for herbal medicines to improve the quality, safety and efficacy of finished herbal products;
2. guide the formulation of national and/or regional GACP guideli...nes and GACP monographs for medicinal plants and related standard operating procedures; and
3. encourage and support the sustainable cultivation and collection of medicinal plants of good quality in ways that respect and support the conservation of medicinal plants and the environment in general.
These guidelines concern the cultivation and collection of medicinal plants and include certain post-harvest operations.

The aim of this report is to: (1) synthesize the findings from selected maternal and newborn related studies in Nepal conducted during 2011-2014, (2) identify areas of improvement in existing interventions, and (3) recommend possible strategies to fulfill such gaps.
Neonatal mortality is a major challenge in reducing child mortality rates in Nepal. Despite efforts by the Government of Nepal, data from the last three demographic and health surveys show a rise in the contribution of neonatal deaths to infant and child mortality. The Government of Nepal has implem...ented community-based programs that were piloted and then scaled up based on lessons learned. These programs include, but are not limited to ensuring safe motherhood, birth preparedness package, community-based newborn care package, and integrated management of childhood illnesses. Despite the implementation of such programs on a larger scale, their effective coverage is yet to be achieved. Health system challenges included an inadequate policy environment, funding gaps, inadequate procurement, and insufficient supplies of commodities, while human resource management has been found to be impeding service delivery. Such bottlenecks at policy, institutional and service delivery level need to be addressed incorporating health information in decision-making as well as working in partnership with communities to facilitate the utilization of available services.

A discussion paper on the scope of the problem, its drivers, and strategies for moving forward for policy, practice, and research
In many protracted emergencies, the prevalence rates of global acute malnutrition (GAM) regularly exceed the emergency threshold of > 15% of children with acute malnutri...tion (< -2 weight-for-height z-scores (WHZ) or with nutritional edema), despite ongoing humanitarian interventions. The widespread scale and long-lasting nature of “persistent GAM” means that it is a policy and programming priority.

The report aims to help policy-makers and programme managers identify the areas that need attention and to work towards effective implementation and enforcement of policies and legislations. The need for alcohol policy-specific infrastructures to support the alcohol policy process, including designa...ted responsible agency, policy and strategy, and law and regulation, is also required at the country level.
The report is presented in three sections. Section 1 gives an insight to the alcohol consumption situation in the WHO South-East Asia Region and cites the alcohol-related problems that the Region is facing. Section 2 illustrates the policy situation in the 10 areas of national action identified in the Global Strategy to Reduce the Harmful Use of Alcohol and gives specific recommendations pertaining to these areas. Section 3 provides overall recommendations.

The document contains a set of indicators that can be used for monitoring traditional and complementary medicine (T&CM) systems in a country.
The core indicator set consists of 16 indicators that were considered essential and collectively able to provide information on T&CM inputs, processes and ou...tputs. A longer list of reference indicators is also available for countries that wish to monitor more indicators or that want to consider alternative metrics that would better suit each country’s T&CM situation, priorities and monitoring capacities.
Each core and reference indicator is accompanied by a set of metadata. This provides information on the indicator rationale, definitions, data elements (numerator, denominator and data disaggregation), frequency of measurement, and data sources. It is a guide towards more standardized data measurement as well as data interpretation.

To implement the set of recommendations on the marketing of foods and non-alcoholic beverages to children
With the growing obesity crisis among children, WHO and other public health advocates and consumer groups have called for restrictions on advertising of ‘unhealthy foods’ high in salt, ...sugar and fat to children. Each day, children in the South East Asia Region are exposed to large volume of marketing of unhealthy foods that may influence children’s food preferences and consumption patterns and is associated with childhood overweight and obesity.
The definition of ‘unhealthy’ is debatable, and therefore, an objective method of describing foods as healthy or unhealthy is needed. A nutrient profile model does just that and therefore, a nutrition profile model for South East Asia was developed. The model is consistent with international guidance for preventing chronic disease and is a simple system with clear cut-offs for defining which foods are not suitable for advertising to children.

The World Health Organization (WHO) endorses the use of population-based prevalence surveys for estimating the prevalence of trachoma. In general, the prevalence of TF in children aged 1–9 years and the prevalence of TT in adults aged ≥ 15 years are measured at the same time in any district bein...g surveyed. This was the approach of the Global Trachoma Mapping Project, which undertook baseline surveys in > 1500 districts worldwide in order to provide the data required to start interventions where needed.
The survey design recommended by WHO is a two-stage cluster random sample survey, which uses probability proportional to size sampling to select 20–30 villages, and random, systematic or quasi-random sampling to select 25–30 households in each of those villages. In most surveys, everyone aged ≥ 1 year living in selected households is examined.

Water, sanitation and hygiene (WASH) are critical in the prevention and care for all of the 17 neglected tropical diseases (NTDs) scheduled for intensified control or elimination by 2020.
Provision of safe water, sanitation and hygiene is one of the five key interventions within the global NTD ...roadmap. Yet to date, the WASH component of the strategy has received little attention and the potential to link efforts on WASH and NTDs has been largely untapped.
Focused efforts on WASH are urgently needed if the global NTD roadmap targets are to be met. This is especially needed for NTDs where transmission is most closely linked to poor WASH conditions such as soil-transmitted helminthiasis, schistosomiasis, trachoma and lymphatic filariasis.
This strategy aims to mobilise WASH and NTD actors to work together towards the roadmap targets.
