Associated Factors With Self-reported Systemic Arterial Hypertension and Diabetes in Brazilian Older Adults: Populational-Based Cross-Sectional Study

Objective: This cross-sectional study aimed to assess the prevalence and associated factors of Systemic Arterial Hypertension (SAH) and Diabetes Mellitus (DM) in older adults.Materials and Methods: Self-reported SAH and DM (outcomes) were obtained through a structured questionnaire. This questionnaire also collected the independent variables (sociodemographic characteristics, use of medication and access to the oral health service). Obesity, physical activity, and tooth loss were assessed using validated instruments. Crude and adjusted Poisson regression with a robust error variance were performed to determine the prevalence ratio (PR) and 95% confidence interval (CI).Results: A total of 282 older adults were included, with the prevalence of 71.28% and 21.63% for SAH and DM, respectively. SAH was significantly associated with increase in the individuals’ age (PR:1.01; 95%CI:1.00–1.02) and the positive diagnosis for obesity (PR:1.24; 95%CI:1.09–1.43). Those that do not use drugs for other conditions  (PR:0.74; 95%CI:0.60–0.71) presented significantly lower PR for SAH. Non-sedentary older adults have the lower RP of DM (PR: 0.42; 95%CI: 0.24–0.74).Conclusions: A high prevalence of SAH and DM was observed among the older adults, and the main associated factors were mainly related to demographic characteristics, general health and behavioral habits

Variação de pH, salinidade e temperatura viabilizantes para estabelecimento do Vibrio cholerae nas águas portuárias da cidade do Rio de Janeiro, Brasil

Introdução: O Vibrio cholerae toxigênico, causador da cólera, possui tolerância ambiental definida quanto ao pH, temperatura e salinidade, o que não o impede de entrar em estado viável, mas não cultivável (VNC), quando as faixas destes parâmetros não lhe são propícias. As zonas portuárias são áreas vulneráveis de introdução do patógeno, devido ao aporte de efluentes urbanos e descarte de água de lastro. Objetivo: O trabalho avaliou se as águas portuárias da cidade do Rio de Janeiro apresentam condições de pH, salinidade e temperatura que possibilitam o estabelecimento do microrganismo. Método: Foram realizadas 22 campanhas de monitoramento em nove pontos, no período de março de 2017 a fevereiro de 2018, buscando sempre diferentes condições climáticas e de maré. Resultados: A maré apresentou ligeira influência na salinidade, enquanto o clima interagiu com todos os fatores. A temperatura e o pH se mantiveram dentro da faixa considerada ótima para o estabelecimento do patógeno, enquanto a salinidade se apresentou, na maioria das vezes, fora da variação ideal. Conclusões: Analisando somente estes fatores, podemos sugerir que, caso estes padrões se mantenham, a região apresenta um risco de sobrevida do microrganismo

Fatores associados à redução de atendimentos odontológicos na Atenção Primária à Saúde no Brasil, com o surgimento da COVID-19: estudo transversal, 2020

Objective: To analyze the associated factors of reductions for dental visits performed in Primary Health Care (PHC) in Brazil during COVID-19 pandemic. Methods: Crosssectional study with PHC dentists. The outcome was a reduction in dental care appointments and that the exposure variables included sociodemographic factors, aspects about personal protective clothing and equipment (PPE) and measures adopted by the Basic Health Unit (UBS) in Brazil after the appearance of COVID. Poisson regression was performed, used to determine the prevalence ratio and 95% confidence interval. Results: Reduction in visits above 50% after the onset of the pandemic was reported by 62.6% of 958 participating. Biosafety protocols (PR=1.04 – 95%CI 1.01;1.07), PPE suggested by the protocols (PR=0.94 – 95%CI 0.89;0.99), and telescreening (PR=0.90 – 95%CI 0.85;0.96) were factors associated with this reduction. Conclusion: The availability of the new PPE and the implementation of telescreening at UBS seem to have minimized the reduction in dental care after the onset of the pandemicObjetivo: Analizar factores asociados a la reducción de consultas odontológicas en Atención Primaria de Salud (APS) en Brasil durante COVID-19.

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Sepse por Serratia marcescens KPC Serratia marcescens KPC sepsis

A resistência aos carbapenems entre as bactérias não fermentadoras de glicose é comumente descrita. Porém, os relatos de resistência aos carbapenems em enterobactérias ainda são fatos isolados. Neste relato de caso, descrevemos um caso de infecção generalizada por Serratia marcescens carreadora de gene blaKPC. No Brasil, já foram relatados casos de isolados de Klebsiella pneumoniae e Escherichia coli carreando gene blaKPC, ficando evidente a emergência desse tipo de carbapenemase e sua disseminação entre espécies diferentes de enterobactérias em nosso país.Carbapenem resistance among Gram-negative non fermentative bacteria is widely known, whereas carbapenem resistance among Enterobacteriaceae is rare. In this study we describe a case of sepsis caused by Serratia marcescens carrying blaKPC gene. In Brazil, cases of KPC have been reported in Klebsiella pneumoniae and Escherichia coli, which shows the emergence of this kind of carbapenemase and its dissemination among different species of Enterobacteriaceae in our country
