ResumoObjetivo: Identificar os principais fatores associados a quedas e fraturas de fêmur em idosos. Métodos: Trata-se de estudo caso-controle (um grupo de casos e dois grupos controle) na proporção de 1:1:1, em que foram estudados 135 indivíduos com idade ≥60 anos, pareados por sexo, no período de 2005 a 2012. Os dados foram coletados por meio de entrevistas nos domicílios dos participantes, e realizou-se levantamento de informações em prontuários. Para análise das diferenças entre proporções e médias entre os grupos, empregaram-se o teste qui-quadrado e o teste t Student, respectivamente. Para o estudo da associação entre variáveis, foram realizadas análises univariadas e multivariadas empregando-se regressão logística. Como medida de efeito, foram empregados odds ratio (OR) e seu intervalo de confiança a 95% (IC95%). Em todas as análises, considerou-se um nível de significância de 5%. Resultados: Após análise multivariada, os fatores de proteção contra fratura de fêmur foram: ouvir bem e possuir corrimão nas escadas de suas residências. Os fatores de risco para fratura de fêmur foram: hipertensão arterial sistêmica, sedentarismo e possuir superfície escorregadia na residência. Os fatores de proteção para queda foram: possuir corrimão nas escadas de suas residências, ser portador de osteoporose e depressão. O fator de risco de queda foi o sedentarismo. Conclusão: As fraturas de fêmur representam importante fator de morbidade em idosos. Conhecer os fatores de risco para fraturas pós-queda em idosos é essencial para o planejamento de ações individuais e coletivas voltadas à prevenção deste agravo e suas consequências. Atividades físicas, planos terapêuticos mais adequados e correção de inadequações nos domicílios desses indivíduos devem ser orientados e incentivados. Palavras

Since the introduction of highly active antiretroviral therapy (HAART) in 1996, there have been worldwide shifts in the causes of hospitalization for patients with HIV/AIDS. The aim of this study was to describe the characteristics of HIV/AIDS patient hospitalizations between 1997 and 2012. This cross-sectional study used a hospital database that centralizes records of admissions in 31 hospitals, both public and private, across 26 municipalities in the interior of São Paulo. In order to verify associations between the variables, we used the prevalence ratio (PR) and a 95% confidence interval. Among 9,797 adults and children, 10,696 admissions were registered, which was equal to 1.09 admissions per patient. Most (62%) of the patients were male, and the predominant age group was 21 and 50 years (63.5%). Mortality was higher among male patients from all age groups (PR= 1.42 [95% CI: 1.28-1.57]; p < 0.05). The main cause of hospitalization (54.5% of the total) was infectious disease, whether opportunistic or not. This was true, even in the post-HAART era. Furthermore, gender and age differences were noted in patient mortality rates.

Objective:To describe and analyze the occurrence of hospitalizations for community-acquired pneumonia in children before and after the pneumococcal 10-valent conjugate vaccine implementation into the National Immunization Program.Methods:This is an ecological study that includes records of children younger than one year old, vaccinated and not vaccinated with the pneumococcal 10-valent conjugate vaccine in the periods pre- and post-inclusion of the vaccine in the National Immunization Program in the area covered by the Regional Health Superintendence of Alfenas, state of Minas Gerais, Brazil. Vaccination was considered as the exposure factor and hospitalization for community-acquired pneumonia as the endpoint, using secondary annual data by municipality. The prevalence ratio and its 95% confidence interval (95%CI) were used to verify the association between variables. The Z test was used to calculate the difference between proportions.Results:Considering the 26 municipalities of the Regional Health Superintendence of Alfenas, there was a significant reduction in hospitalizations for community-acquired pneumonia in children younger than one year of age, with prevalence ratio (PR)=0.81 (95%CI: 0.74-0.89; p<0.05), indicating a 19% lower prevalence of hospitalization for community-acquired pneumonia in the post-vaccination period.Conclusions:The results suggest the effectiveness of the pneumococcal 10-valent conjugate vaccine in preventing severe cases of community-acquired pneumonia in children younger than one year of age.

Objective:To determine the prevalence of overweight and obesity in schoolchildren aged 10 to 16 years and its association with dietary and behavioral factors.Methods:Cross-sectional study that evaluated 505 adolescents using a structured questionnaire and anthropometric data. The data was analyzed through the T Test for independent samples and Mann-Whitney Test to compare means and medians, respectively, and Chi2 Test for proportions. Prevalence ratio (RP) and the 95% confidence interval was used to estimate the degree of association between variables. The logistic regression was employed to adjust the estimates to confounding factors. The significance level of 5% was considered for all analysis.Results:Excess weight was observed in 30.9% of the schoolchildren: 18.2% of overweight and 12.7% of obesity. There was no association between weight alterations and dietary/behavioral habits in the bivariate and multivariate analyses. However, associations were observed in relation to gender. Daily consumption of sweets [PR=0.75 (0.64-0.88)] and soft drinks [PR=0.82 (0.70-0.97)] was less frequent among boys; having lunch daily was slightly more often reported by boys [OR=1.11 (1.02-1.22)]. Physical activity practice of (≥3 times/week) was more often mentioned by boys and the association measures disclosed two-fold more physical activity in this group [PR=2.04 (1.56-2.67)] when compared to girls. Approximately 30% of boys and 40% of girls stated they did not perform activities requiring energy expenditure during free periods, with boys being 32% less idle than girls [PR=0.68 (0.60-0.76)].Conclusions:A high prevalence of both overweight and obesity was observed, as well as unhealthy habits in the study population, regardless of the presence of weight alterations. Health promotion strategies in schools should be encouraged, in order to promote healthy habits and behaviors among all students.

The prevalence of obesity among children and adolescents in Brazil is high and urgently needs measures to prevent consequences associated with the disease, as well as measures to reduce the impact, in the short term, the overweight and childhood obesity.

Este artigo tem por objetivo identificar, nas decisões do Superior Tribunal de Justiça (STJ), as principais causas dos danos decorrentes da prática médica obstétrica no momento do parto. O estudo analisou 21 decisões julgadas pela corte entre 2004 e 2014 relacionadas a indenizações judiciais na obstetrícia. O critério de seleção dos casos utilizou como método a busca de decisões no site do STJ, cujos descritores foram: "parto", "erro médico"; "médico"; "paciente"; "profissional da saúde"; "dano moral"; "dano material"; "SUS"; "responsabilidade civil" e "indenização por erro médico". O Rio de Janeiro foi o estado com maior número de ações indenizatórias (28,6%) apreciadas pelo STJ, seguido de São Paulo e Minas Gerais, com 14,3% cada um. No tocante aos réus que figuraram no polo passivo das demandas, 38,1% eram médicos e hospitais. Verificou-se que 71% das supostas falhas médicas que originaram as ações ocorreram durante a realização do parto natural, contra 29% dos casos de cesariana. A principal causa dos danos relatados foi a demora na realização do parto, seguida dos traumatismos. Apesar de pesquisas demonstrarem que a cesariana oferece maiores riscos para a parturiente e o feto, os resultados obtidos das decisões judiciais analisadas pelo STJ evidenciaram que os danos que resultaram sequelas irreversíveis no nascituro foram recorrentes nos casos relacionados ao parto natural, sugerindo que atenção especial deve ser dada à formação médica obstétrica, bem como à compreensão dos aspectos socioculturais envolvendo a indicação e a escolha pelo tipo de parto.

Introduction: Mathematical models have been used to obtain long-term forecasts of the COVID-19 epidemic. Methods: The daily COVID-19 case count in two Brazilian states was used to show the potential limitations of long-term forecasting through the application of a mathematical model to the data. Results: The predicted number of cases at the end of the epidemic and at the moment that the peak occurs, is highly dependent on the length of the time series used in the predictive model. Conclusions: Predictions obtained during the course of the COVID-19 pandemic need to be viewed with caution.
