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.

Mund-Nasen-Bedeckung im öffentlichen Raum als weitere Komponente zur Reduktion der Übertragungen von COVID-19. Strategieergänzungen zu empfohlenen Schutzmaßnahmen und Zielen (3. Update) Das RKI empfiehlt ein generelles Tragen einer Mund-Nasen-Bedeckung (MNB) in bestimmten Situationen im öffentl...ichen Raum als einen weiteren Baustein, um Risikogruppen zu schützen und den Infektionsdruck und damit die Ausbreitungsgeschwindigkeit von COVID-19 in der Bevölkerung zu reduzieren. Diese Empfehlung beruht auf einer Neubewertung aufgrund der zunehmenden Evidenz, dass ein hoher Anteil von Übertragungen unbemerkt erfolgt, und zwar bereits vor dem Auftreten von Krankheitssymptomen. Ziel des im Epidemiologischen Bulletin 19/2020 veröffentlichten Artikels ist es, eine kurze Übersicht zum fachlichen Hintergrund der Empfehlung zu geben und zu erläutern, welche Dinge hierbei zu berücksichtigen sind.

Obesity and diabetes are affecting the peoples of the Americas at high and increasing rates. National surveys demonstrate that obesity is increasing in prevalence among all age groups; 7% to 12% of children under 5 years old and
one-fi fth of adolescents are obese, while rates of overweight and obe...sity among adults approach 60%. Obesity is the major modifi able risk factor for diabetes.

Cardiovascular disease (CVD) is the leading cause of global deaths, with the majority occurring in low- and middle-income countries (LMIC). The primary and secondary prevention of CVD is suboptimal throughout the world, but the evidence-practice gaps are much more pronounced in LMIC. Barriers at the... patient, health-care provider, and health system level prevent the implementation of optimal primary and secondary prevention. Identification of the particular barriers that exist in resource-constrained settings is necessary to inform effective strategies to reduce the identified evidence-practice gaps. Furthermore, targeting modifiable factors that contribute most significantly to the global burden of CVD, including tobacco use, hypertension, and secondary prevention for CVD will lead to the biggest gains in mortality reduction. We review a select number of novel, resource-efficient strategies to reduce premature mortality from CVD, including: (1) effective measures for tobacco control; (2) implementation of simplified screening and management algorithms for those with or at risk of CVD, (3) increasing the availability and affordability of simplified and cost-effective treatment regimens including combination CVD preventive drug therapy, and (4) simplified delivery of health care through task-sharing (non-physician health workers) and optimizing self-management (treatment supporters). Developing and deploying systems of care that address barriers related to the above, will lead to substantial reductions in CVD and related mortality.

There has never been a more critical moment to invest in WHO, and strengthen the unique role it plays in global health. Now is the time to sustainably finance WHO and invest in a healthy return for all.
In 2019, the Task Force on Fiscal Policy for Health concluded that taxes on tobacco, alcohol, and sugar-sweetened beverages were a highly effective but greatly underused policy tool to reduce consumption, save lives, and raise domestic resources. The Task Force estimated that if all countries increa...sed their excise taxes to raise prices by 50 percent, over 50 million premature deaths could be averted worldwide over the next 50 years while
raising over USD 20 trillion of additional revenue. Since the Task Force first convened, the world has faced a “polycrisis,” including a global pandemic, an economic recession, and the outbreak of wars in Europe and the Middle East. Against this backdrop, the world has also experienced prolonged health and fiscal crises. Health systems, weakened by the COVID-19 pandemic, lack sufficient financing to rebuild and respond to the surging noncommunicable diseases epidemic caused by uncontrolled risk factors such as tobacco, alcohol, and sugar consumption. Opportunities to raise domestic resources are limited and debt burdens have squeezed budgets. The period from 2019 to 2027 risks becoming a “lost decade” for health and social policies, with 110 countries facing little prospect of any
ability to raise government revenues beyond current levels. In this paper, we describe the current health and fiscal crises and review the contribution that health taxes could make in turning around this dire situation. We conclude that taxes on tobacco, alcohol, and
sugar-sweetened beverages are an ideal policy solution—good for the budget and good for health. These taxes are relatively quick to implement, and, unlike other taxes, do not put economic growth at risk—a vital benefit in the current era.

Le Plan Stratégique National de Lutte contre le Paludisme 2023–2027 de la Guinée vise à réduire de 80 % l’incidence et la mortalité liées au paludisme d’ici 2027, en s’appuyant sur les leçons des années précédentes. Il prévoit des actions renforcées de prévention (moustiquaire...s, lutte antivectorielle, chimio-prévention saisonnière, prévention chez les femmes enceintes et les enfants), une amélioration de la prise en charge des cas à tous les niveaux (public, privé, communautaire), ainsi qu’un renforcement de la gestion, des ressources, de la gouvernance, de la communication et de l’évaluation. L’objectif final est de guider le pays vers la pré-élimination du paludisme, en assurant l’accès universel à des soins de qualité et en mobilisant tous les acteurs nationaux et internationaux.

The Guidelines for the Use of the APCA African Palliative Outcome Scale (POS) has been developed by the APCA, in collaboration with
stakeholders, to help appropriately trained health practitioners and researchers across the region to utilise the APCA African POS in their work place (Powell et... al, 2007; Warria et al, 2007). Not only do the guidelines provide a clear rationale for measuring palliative care outcomes, but they also outline practical information on how to use the tool to collect data and analyse its results. So why is there a need for these guidelines?
Palliative care as a concept and discipline is not well understood across Africa, and its development is still embryonic in many countries. While there are many obstacles that hinder palliative care development on the continent, a key challenge is the lack of accurate information about the palliative care being provided and its outcomes. The APCA African POS is a useful tool to help us measure these outcomes and, given that
measuring palliative care outcomes remains a relatively new concept, it is important to guide people on how to use the tool. Of course, these guidelines are not intended to address everything related to the measurement of palliative care outcomes; they contain only essential information for providers. More detailed information on the use of outcome tools, and in particular within the research setting, can be gained from contacting relevantly trained professionals.

MINDSPACE is an acronym developed by the UK's behavioural insights team to summarise nine key influences on human behaviour: Messenger, Incentives, Norms, Default, Salience, Priming, Affect, Commitment, and E...go. These effects have been used in various settings to design interventions that encourage positive behaviours. Currently, over 200 institutionalised behavioural insight teams exist internationally, which may draw upon the MINDSPACE framework to inform policy and improve public services.
