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 purpose of cancer screening tests is to detect pre-cancer or early-stage cancer in asymptomatic individuals so that timely diagnosis and early treatment can be offered, where this treatment can lead to better outcomes for some people.
The aim of a cancer screening programme is either to reduc...e mortality and morbidity in a population by early detection and early treatment of a cancer (for example, breast screening) or to reduce the incidence of a cancer by identifying and treating its precursors (such as cervical and colorectal screening).
This short guide is designed to be a quick reference that contains the important ideas about cancer screening. Readers should refer to other publications for comprehensive discussion and detailed guidance on cancer screening programmes.

Tuberculosis (TB) is, and should be, a curable disease; however, each year significant numbers of patients acquire or develop drug-resistant TB, which has a much lower cure rate. Patients with drug-resistant TB have a high prevalence of symptoms; hence, staff caring for these patients should h...ave some familiarity with palliative care, so that general palliative care principles are available to all patients. The timely identification, and addressing, of adverse events occurring during the treatment course is considered as general palliative care for those receiving curative treatment. This publication summarizes the general palliative care approach, which is recommended for use in settings and services that occasionally treat palliative care patients, but do not provide palliative care as the main focus of their work. The review focuses on 18 high TB priority countries of the WHO European Region.

Overview of Community-Based Integrated Management of Childhood Illnesses
The speed of developing diagnostics for SARS-CoV-2, the causative agent of coronavirus disease 2019 (COVID-19), has been quite remarkable. Diagnostics have focused on nucleic acid amplification testing (NAAT) to identify infected individuals in acute-phase disease for timely implementation of mitiga...tion strategies and case management. More and more immunodiagnostics, mostly rapid diagnostic tests, are being made available as an alternative to NAATs. This type of test can be used out-of-laboratory conditions at large scale.

síntesis de hallazgos en cinco países de América Latina
Esta nueva hoja de ruta traza el camino a seguir para las acciones a nivel de país con el fin de alcanzar un ambicioso conjunto de objet ivos de prevención del VIH para 2025. Estos objetivos surgieron de la Declaración Política sobre el VIH y el sida de 2021, que la Asamblea General de las Nacio...nes Unidas adoptó en junio de 2021 y están respaldados por la Estrategia mundial contra el sida (2021-2026). La Estrategia establece los principios, los enfoques, el área de acción prioritaria y los objetivos programáticos para la respuesta mundial al VIH.

El Plan de Respuesta Humanitaria tiene como objetivo llegar a 2,6 millones de personas vulnerables hasta finales del año, que representa un número limitado de las personas en necesidad, e incluye 1,2 millones de niñas, niños y adolescentes. Para alcanzar estos objetivos, las Naciones Unidas y su...s socios requieren $223 millones de dólares. El Plan tiene sus fundamentos en la estrategia de escalamiento que se inició en octubre de 2018 por Naciones Unidas para responder a las necesidades humanitarias y de otras iniciativas de respuestas implementadas por otros actores humanitarios. Este Plan permitirá fortalecer las capacidades operacionales de los actores humanitarios y poner las bases para alcanzar una población meta más amplia en 2020. El Plan será actualizado de acuerdo a información disponible, incluyendo nuevas evaluaciones.

This evaluation is the first systematic effort by UNICEF to generate evidence on how well its global as well as country level Community Management of Acute Malnutrition (CMAM) strategies have worked, including their acceptance and ownership in various contexts and appropriateness of investments in c...apacity development and supply components. Overall, the evaluation recommends that UNICEF continue to promote and support CMAM as a viable approach to preventing and addressing severe acute malnutrition (SAM), with an emphasis on prevention through strengthening community outreach and integrating CMAM into national health systems and with other intervention

La tendencia al calentamiento en América Latina y el Caribe continuó en 2021. La tasa media de aumento de las temperaturas fue de aproximadamente 0,2 °C por década entre 1991 y 2021, en comparación con los 0,1 °C por década registrados entre 1961 y 1990.En 2021, la temperatura se situó por e...ncima de la media de 1981-2010 en todas las subregiones, habiéndose registrado la anomalía máxima de +0,59 (±0,1 °C) en la región de México y América Central, lo que corresponde a +0,97 (±0,1 °C) por encima del período de referencia de 1961-1990 de la OMM para el cambio climático.
