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.

Detonation of a nuclear weapon or activation of a radiological dispersal device could cause radioactively contaminated decedents. These guidelines are designed to address both of these scenarios. They could also be applicable in other instances where decedents’ bodies are contaminated with radioa...ctive material (e.g. reactor accidents, transportation accidents involving radioactive material, or
the discharge of a decedent from a hospital after injection or implantation of a radiopharmaceutical). These guidelines suggest ways for medical examiners, coroners, and morticians to deal with loose surface contamination, internal contamination, or shrapnel on or in decedents’ bodies.

In response to the first cases of coronavirus disease 2019 (COVID-19) reported on the continent, many African Union Member States implemented large-scale public health and social measures (PHSM) rapidly. These measures were aimed at reducing transmission and the number of new cases being reported, p...rotecting the most vulnerable populations, and allowing time for countries to ramp up critical healthcare and diagnostic services. While these quick actions bought time for Member States, the negative socio-economic impacts are being felt widely, and countries are now exploring how best to ease these measures back while still managing the outbreak.

Does accepting palliative care mean our family is giving up on ot...her treatments?
How can my child’s pain be managed?
How can our family get palliative care?
