HIV testing programmes need to ensure that all clients who test for HIV are provided with correct diagnoses. The accuracy of HIV testing is critical to prevent misdiagnosis, as the consequences of giving an incorrect test result can be serious for clients, HIV testing services, HIV programmes and pu...blic health.
With the evolution of global HIV epidemiology, HIV testing approaches must also evolve to maintain accuracy and efficiency in population-level diagnosis. Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used. As a result of changing epidemiology and declining HIV positivity in testing, WHO recommends all countries use a standard three-test strategy to ensure a PPV of at least 99%, minimizing false-positive misdiagnosis. The WHO-recommended HIV testing strategy, along with quality assurance measures such as retesting to verify a positive diagnosis prior to initiation of HIV treatment, is cost-effective as it prevents misdiagnosis and unnecessary initiation of costly lifelong treatment.
This implementation guide provides practical advice on switching to a three-test strategy and instituting other measures that can help national HIV programmes deliver high-quality, accurate HIV testing services and ensure that misdiagnosis is minimized.

The chapter Closing the Gap: The Health Disparities of Older LGBTI People in the Americas, is part of the publication series titled ‘Decade of Healthy Aging: situation and challenges’. In order to outline the current knowledge available on the situation of health and well-being of older persons ...in the Americas at the beginning of the United Nations Decade of Healthy Aging (2021-2030), this document presents data and existing evidence different forms of discrimination and mistreatment older people face due to their sexual orientation and gender identities that ultimately increase health disparities. Previous studies on LGBTI older people offer valuable information on the lived experiences of these communities and demonstrate that they face unique challenges with aging, emphasizing the difficulties related to access to care. Very few studies on older people and aging include a focus on sexual orientation or gender identity; however, it is possible to point out that HIV/AIDS is one of the most significant health disparities confronting LGBTI older persons, followed by physical and mental health problems, substance use, social isolation, poverty, and the lack of access to quality healthcare, including long-term care facilities or other institutions. Closing the gap in access and quality of health and care services is an imperative to increase longevity, health status and quality of life of LGBTI older people.

The aim of the present paper is to review capacity building in public health nutrition (PHN), the need for which has been stressed for many years by a range of academics, national and international organisations. Although great strides have been made worldwide in the science of nutrition, there rema...in many problems of undernutrition and increasingly of obesity and related chronic diseases. The main emphasis in capacity building has been on the nutrition and health workforce, but the causes of these health problems are multifactorial and require collaboration across sectors in their solution. This means that PHN capacity building has to go beyond basic nutrition and beyond the immediate health workforce to policy makers in other sectors. The present paper provides examples of capacity building activities by various organisations, including universities, industry and international agencies. Examples of web-based courses are given including an introduction to the e-Nutrition Academy. The scope is international but with a special focus on Africa. In conclusion, there remains a great need for capacity building in PHN but the advent of the internet has revolutionised the possibilities.

Vitamin A supplementation (VAS) programs targeted at children aged 6–59 months are implemented in many countries. By improving immune function, vitamin A (VA) reduces mortality associated with measles, diarrhea, and other illnesses. There is currently a debate regarding the relevance of VAS, but a...midst the debate, researchers acknowledge that the majority of nationally-representative data on VA status is outdated. To address this data gap and contribute to the debate, we examined data from 82 countries implementing VAS programs, identified other VA programs, and assessed the recentness of national VA deficiency (VAD) data.
