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.

The aim of this handbook is to provide network members and other laboratories involved in the diagnosis of tuberculosis, with an agreed list of key diagnostic methods and their protocols in various areas of TB diagnosis, ranging from microbiological diagnosis of active TB to the diagnosis of latent ...TB infection. This handbook offers a single source of reference by compiling all methods, with a strong focus on standard (reference) and evidence-based methods. In so doing, it will also contribute to the improvement of disease surveillance data for Europe.

This Rapid Advice Guideline updates the Interim Guidance on the “Assessment of infants with microcephaly in the context of Zika virus” published in February 2016 (WHO/ZIKV/MOC/16.3). The recommendations provides guidance on the screening, clinical assessment, neuroimaging, laboratory investigati...on and follow-up of children born to women living in areas of Zika virus transmission. The Guideline summarises the evidence base and rationale in support of the recommendations and expands the scope to address complications beyond microcephaly and what is now referred to as the congenital Zika virus syndrome

Iron deficiency is one of the most common forms of nutritional deficiencies, particularly among vulnerable groups such as women, children and low-income populations. Iron deficiency often precedes anaemia, and anaemia during pregnancy is one of the strongest predictors of anaemia duri...ng the postpartum period, beginning just after childbirth throughout the subsequent 6 weeks. The consequences of iron deficiency and anaemia during the postpartum period can be serious and have long-term health implications for the mother and her infant.
This guideline reviews the evidence on the safety and effectiveness of iron supplementation in postpartum women.

Recently, a renewed interest in large-scale community health worker (CHW) programs has been seen globally. This renewal provides an opportune moment to take stock of issues and challenges such programs face and what can be done to make them as effective as possible. With this in mind, this manual is... intended to be used a practical guide for policymakers and program
managers wishing to develop or strengthen a CHW program, drawing lessons from other countries that have implemented CHW programs at-scale. Throughout, we discuss major policy and programmatic issues that decision-makers and planners need to consider when designing, implementing, scaling up or strengthening a national-level CHW program. We offer an overview
of specific challenges CHW programs face, country lessons, tools, and other resources that may be helpful, while incorporating relevant programmatic examples as much as possible.

In recent years Terre des Hommes Netherlands observed the steady rise of a new form of child sexual exploitation. One that is enabled and fuelled by rapid technological advances, increasing global connectivity, persisting poverty rates, and growing disparity in the global distribution of resources. ...Terre des Hommes Netherlands received alarming signals from collaborating project partners from the Philippines that new commercial child exploitation trades are evolving and spreading parallel to rising global Internet access rates and developments in communications technology.
Webcam child sex tourism is evidently growing, closely related to child prostitution, child trafficking and child abuse. What is not clear however, are the psychological and social consequences of this new phenomenon. To date, no research has been done on the psychosocial consequences of webcam sex for children. The aim of this research is therefore to gain more knowledge on the psychosocial consequences of webcam child sex tourism for children and to give insight into the antecedent factors that play a role.
