RESUMO Lutzomyia longipalpis (Lutz & Neiva, 1912) é o vetor do agente da leishmaniose visceral (LV) no Novo Mundo de maior relevância epidemiológica. Em 25 de outubro de 2023, o Centro de Informações Estratégicas em Vigilância em Saúde de Macapá detectou um caso de LV no bairro Km9 desse município. O objetivo deste estudo foi identificar as espécies de flebotomíneos nessa área a fim de auxiliar na confirmação da autoctonia do caso. Foram coletados 12 espécimes, desses, cinco foram de […]

ABSTRACT This study determines the factors of abandonment of tuberculosis treatment in the public health network of Cali, Colombia, during years 2016 to 2018. We conducted an operational case-control investigation including 224 patients with tuberculosis (112 abandoned treatment and 112 completed it). We found that treatment abandonment for tuberculosis is driven by factors related to the individuals and health services that facilitate non-adherence and drive them away from the care provided in medical institutions.

ABSTRACT We have previously reported the impact of covid-19 pandemic on breast cancer screening, in Brazil: among women aged 50–69 years, mammography attendance decreased by 42% in public healthcare (SUS), comparing 2019 and 2020. In this short communication, we wish to present: a) an update of the number of mammograms performed, in 2021; b) an exploratory analysis of the characteristics of the screened population between 2019 and 2021. A total of 1.675.307 mammograms were performed in 2021, nearly 15% lower […]

ABSTRACT Knowledge about HIV transmission and prevention is a necessary step for adopting preventive behaviors. We assessed HIV knowledge and its correlation with the perceived accuracy of the “Undetectable = Untransmittable” (U=U) slogan in an online sample with 401 adult Brazilians. Overall, 28% of participants showed high HIV knowledge level. The perceived accuracy of the U=U slogan significantly correlated with HIV knowledge. Younger participants, those reporting lower income or lower education, or who had never tested for HIV showed poorer […]

ABSTRACT This study aimed to verify socio-demographic and baseline clinical factors associated with death in a hospital cohort of patients with COVID-19. A retrospective cohort study was conducted between February and December 2020 in a university hospital in the city of São Paulo, using Hospital Epidemiology Center data. RT-PCR-positive patients were selected to compose the sample (n = 1,034). At the end of the study, 362 (32%) patients died. In this cohort, age equal to or greater than sixty years […]

ABSTRACT Interrupted time series analyses were conducted to measure the impact of social distancing policies (instituted on March 22, 2020) and of subsequent mandatory masking in the community (instituted on May 4, 2020) on the incidence and effective reproductive number of COVID-19 in São Paulo State, Brazil. Overall, the impact of social distancing both on incidence and Rt was greater than the incremental effect of mandatory masking. Those findings may reflect either a small impact of face masking or the […]

ABSTRACT We report cognitive, language and motor neurodevelopment, assessed by the Bayley-III test, in 31 non-microcephalic children at age 3 with PCR-confirmed maternal Zika virus exposure (Rio de Janeiro, 2015–2016). Most children had average neurodevelopmental scores, however, 8 children (26%) presented delay in some domain. Language was the most affected: 7 children (22.6%) had a delay in this domain (2 presenting severe delay). Moderate delay was detected in the cognitive (3.2%) and motor (10%) domains. Maternal illness in the third […]

RESUMO Este estudo descreve modificações no peso corporal de participantes da coorte NutriNet Brasil (n = 14.259) ocorridas durante a pandemia de covid-19. Foram analisados dados informados em período anterior ao início da pandemia (26/01/2020 a 18/03/2020) e cerca de 6 meses após (14/09/2020 a 19/10/2020). O ganho de peso ≥ 2 kg alcançou 19,7% dos participantes, mostrando-se diretamente associado ao sexo masculino, à menor escolaridade e à presença prévia de excesso de peso, sendo inversamente associado à idade. A […]

RESUMO No Brasil, quase metade da população não tem acesso a coleta e tratamento de esgotos. Os efluentes não tratados, devido a contaminação das águas de reservatórios para abastecimento humano, geram florações de cianobactérias – e esses microrganismos produzem toxinas, como a saxitoxina, uma neurotoxina bastante potente e presente nos reservatórios da região Nordeste. Estudo recente confirmou que a ingestão crônica de água contaminada com neurotoxinas associada a infeção pelo zika vírus em camundongos prenhes poderia levar a desfecho semelhante […]

ABSTRACT The World Health Organization has emphasized that one of the most important questions to address regarding the covid-19 pandemic is to understand risk factors for disease severity. We conducted a brief review that synthesizes the available evidence and provides a judgment on the consistency of the association between risk factors and a composite end-point of severe-fatal covid-19. Additionally, we also conducted a comparability analysis of risk factors across 17 studies. We found evidence supporting a total of 60 predictors […]
