Resumo A pandemia de COVID-19 tem desafiado pesquisadores e gestores a encontrar medidas de saúde pública que evitem o colapso dos sistemas de saúde e reduzam os óbitos. Esta revisão narrativa buscou sistematizar as evidências sobre o impacto das medidas de distanciamento social na epidemia de COVID-19 e discutir sua implementação no Brasil. Foram triados artigos sobre o efeito do distanciamento social na COVID-19 no PubMed, medRXiv e bioRvix, e analisados atos do poder público nos níveis federal e estadual para sumarizar as estratégias implementadas no Brasil. Os achados sugerem que o distanciamento social adotado por população é efetivo, especialmente quando combinado ao isolamento de casos e à quarentena dos contatos. Recomenda-se a implementação de medidas de distanciamento social e de políticas de proteção social para garantir a sustentabilidade dessas medidas. Para o controle da COVID-19 no Brasil, é imprescindível que essas medidas estejam aliadas ao fortalecimento do sistema de vigilância nos três níveis do SUS, que inclui a avaliação e uso de indicadores adicionais para monitorar a evolução da pandemia e o efeito das medidas de controle, a ampliação da capacidade de testagem, e divulgação ampla e transparente das notificações e de testagem desagregadas.
Urban populations, in diverse geographic settings, experience increases in mortality due to both high and low temperatures. The effects of heat and cold vary depending on climate and non-climate factors such as the population disease profile and age structure. Although such populations will undergo some adaptation to increasing temperatures, many are likely to have substantial vulnerability to climate change. Additional research is needed to elucidate vulnerability within populations.
This study presents an overview of public sector interventions and progress made on the women's and child health front in Brazil between 1990 and 2015. We analyzed indicators of antenatal and labor and delivery care and maternal and infant health status using data from the Live Birth Information System and Mortality Information System, national surveys, published articles, and other sources. We also outline the main women's and child health policies and intersectoral poverty reduction programs. There was a sharp fall in fertility rates; the country achieved universal access to antenatal and labor and delivery care services; access to contraception and breastfeeding improved significantly; there was a reduction in hospital admissions due to abortion and in malnutrition. The rates of congenital syphilis, caesarean sections and preterm births remain excessive. Under-five mortality decreased by more than two-thirds, but less pronounced for the neonatal component. The maternal mortality ratio decreased from 143.2 to 59.7 per 100 000 live births. Despite worsening scores or levelling off across certain health indicators, the large majority improved markedly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
