Brazilian media and science communicators must understand the main characteristics of misinformation in social media about COVID-19, so that they can develop attractive, up-to-date and evidence-based content that helps to increase health literacy and counteract the spread of false information.
Food environments are usually defined as the settings with all the different types of
food made available and accessible to people as they go about their daily lives.
That is, the range of food in supermarkets, small retail outlets, wet markets, street
food stalls, coffee shops, tea houses, s
...
chool canteens, restaurants, and all the other
venues where people buy and eat food. These environments differ enormously depending on the context. They can be extensive and diverse, with a seemingly endless array of options and price ranges, or they can be sparse, with very few options on offer. Because they determine what food consumers can access at a given moment in time, at what price, and with what degree of convenience, food environments both constrain and prompt the consumer’s choice.Food environments are influenced by the food systems which supply them, and vice versa. Food systems encompass the entire range of activities, people and institutions involved in the production, processing,
marketing, consumption and disposal of food (FAO, 2013). They include but are not limited to food supply chains. Making food systems nutrition-sensitive can contribute to addressing all forms of malnutrition, as food systems determine whether the food needed for good nutrition are available, affordable, acceptable and of adequate
quantity and quality. How closely food systems and food environments are interrelated and interdependent, and the degree to which external factors affect nutrition outcomes, varies from setting to setting.Many of today’s food systems
and food environments are challenged in supporting consumer choices that are
consistent with healthy diets and good nutrition. Consumers are not making choices based on nutrition and health, and poor diet is now the number one risk factor for death and disability worldwide (GBD, 2015). Food systems that do not enable healthy diets are increasingly recognized as an underlying cause of malnutrition (GLOPAN, 2016), and malnutrition, irrespective of form, has a huge cost. Economic costs associated with undernutrition are estimated at $1-2 trillion per year, about 2-3% of global GDP (FAO, 2013); the global economic cost of obesity and associated diet-related non-communicable diseases is estimated at $2 trillion per year, about 2.8% of global GDP (McKinsey, 2014). Influencing food environments for promoting healthy diets is an emerging strategy to address today’s nutrition challenges.

Klinische Falldefinition einer Post-COVID-19-Erkrankung gemäß Delphi-Konsens, 6.Oktober 2021
recommended
Die WHO hat mit Hilfe der Delphi-Methode eine klinische Falldefinition für das Post-COVID-19-Syndrom entwickelt, die 12 Domänen umfasst und in allen Bereichen verwendet werden kann. Diese erste Version wurde von Patienten, Forschern und anderen Personen aus allen WHO-Regionen entwickelt, wobei dav

on ausgegangen wird, dass sich die Definition ändern kann, wenn sich neue Erkenntnisse ergeben und sich unser Verständnis der Folgen von COVID-19 weiterentwickelt.
Die Post-COVID-19-Erkrankung tritt bei Personen mit einer wahrscheinlichen oder bestätigten SARS-CoV-2-Infektion in der Anamnese auf, in der Regel drei Monate nach dem Auftreten von COVID-19 mit Symptomen, die mindestens zwei Monate anhalten und nicht durch eine andere Diagnose erklärt werden können. Zu den häufigen Symptomen gehören Müdigkeit, Kurzatmigkeit, kognitive Störungen, aber auch andere Symptome, die sich im Allgemeinen auf das tägliche Leben auswirken. Die Symptome können nach der anfänglichen Genesung von einer akuten COVID-19-Episode neu auftreten oder nach der ersten Erkrankung fortbestehen. Die Symptome können auch schwanken oder im Laufe der Zeit wieder auftreten.

e todas las regiones de la OMS, en el entendimiento de que la definición puede cambiar a medida que surjan nuevas pruebas y siga evolucionando nuestra comprensión de las consecuencias de la COVID-19.
La afección posterior a la COVID-19 se produce en personas con antecedentes de infección probable o confirmada por el CoV-2 del SRAS, normalmente a los 3 meses de la aparición de la COVID-19 con síntomas y que duran al menos 2 meses y no pueden explicarse por un diagnóstico alternativo. Los síntomas más comunes son la fatiga, la dificultad respiratoria y la disfunción cognitiva, pero también otros, y generalmente tienen un impacto en el funcionamiento diario. Los síntomas pueden ser de nueva aparición tras la recuperación inicial de un episodio agudo de COVID-19 o persistir desde la enfermedad inicial. Los síntomas también pueden fluctuar o recaer con el tiempo.

Adolescent girls and young women (AGYW) remain disproportionately affected by HIV in Eastern and Southern Africa (ESA), with 26 per cent of new infections attributed to this population.

thods. Oral Pre-exposure Prophylaxis (PrEP) is proven to be highly effective as an additional prevention choice for reducing the risk of HIV acquisition, including for AGYW. Successful uptake and adherence to PrEP is critical in its effectiveness as an HIV prevention method, however, the current demand for PrEP by AGYW is low with suboptimal adherence.
Within the ESA region, there is currently great impetus to address these challenges and scale up PrEP for AGYW. A critical aspect of this is to leverage the learnings and evidence from implementation of how to improve the demand and quality of PrEP programming for this population. Improving the Quality of Pre-Exposure Prophylaxis Implementation for Adolescent Girls and Young Women in Eastern and Southern Africa examines the current efforts in the region to accelerate and scale up evidence-based PrEP delivery platforms. The implementation brief provides current knowledge and builds on WHO guidance to provide key considerations for implementation, including driving demand and improving quality, as well as focus on wider combination prevention and integration agendas.

ities in these diseases is essential for taking strategic, evidence-informed action to realize our shared vision of ending the epidemics of HIV, TB and malaria.
This report presents the first comprehensive analysis of the magnitude and patterns of socioeconomic, demographic and geographic inequalities in disease burden and access to services for prevention and treatment.
The results confirm there have been improvements in service coverage and decreased disease burden at the national level over the past decade. But they also reveal an uncomfortable reality: unfair inequalities between population subgroups within countries are widespread and have remained largely unchanged over the past decade. For some disease indicators, inequalities are even worsening.
Moreover, the report points to the persistent lack of available data to fully understand inequality patterns in HIV, TB and malaria. Collecting data to improve the monitoring of inequalities in these diseases is vital to develop targeted responses for impact.
There are, encouragingly, isolated successes in reducing inequities. Change is possible when deliberate action is taken to reach disadvantaged populations.
