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.

Internationally, there is a growing concern over antimicro-bial resistance (AMR) which is currently estimated to ac-count for more than 700,000 deaths per year worldwide. If no appropriate measures are taken to halt its pro-gress, AMR will cost approximately 10 million lives andabout US$100 trillion... per year by 2050. In contrast tosome other health issues, AMR is a problem that con-cerns every country irrespective of its level of incomeand development as resistant pathogens do not respect borders.Despite the threat presented by AMR, the 2014 WorldHealth Organization (WHO) and the recent O’Neill re-port describe significant gaps in surveillance, standardmethodologies and data sharing. The 2014 WHOreport identified Africa and South East Asia as the regions without established AMR surveillance systems.

In 1998 the Swedish Veterinary Association decided to adopt a general policy for the use of antibiotics in animals. Since then specifi c policies for the use of antibiotics in dogs and cats have been adopted and in 2011 Guidelines for the use of Antibiotics in Production animals – Cattle and Pigs,... were accepted. By decision of the board of the Swedish Veterinary Society (SVS) these guidelines have been updated. Th e over-arching goal of SVS is to achieve a low and controlled use of antibiotics in Swedish animal production so that the fi rst-hand choices of treatment remain effi cient and that the spread of antimicrobial resistance – among animals and herds as well as in the food chain – is kept at a minimum. Keeping antimicrobial resistance in animals low is important also for human health, since we are all part of the same ecosystem. Th e authors of these guidelines hope that they may be useful for veteri-narians in clinical practice when deciding on treatments for common diseases and ailments caused by bacteria. Sometimes the decision may even be to refrain from use of antibiotics and chose other ways of improving herd health.

Recommendations for health care professionals – the experience from Latvia
This handbook builds on lessons learned from surveys implemented 2015-2017 and advice provided by the Global task force on TB patient cost surveys. It provides a standardized methodology for conducting health facility-based cross-sectional surveys to assess the direct and indirect costs incurred by ...TB patients and their households. In addition, it provides recommendations on results dissemination, engaging across sectors in policy dialogue and enabling action and related research for effective modifications in care delivery models, in patient support, and wider cross-sectoral interventions.

Following review of the latest evidence, WHO recommends that TB-LAMP can be used as a replacement for microscopy for the diagnosis of pulmonary TB in adults with signs and symptoms of TB. It can also be considered as a follow-on test to microscopy in adults with signs and symptoms of pulmonary TB, e...specially when further testing of sputum smear-negative specimens is necessary.
