Introdução: distúrbios do sono são comuns na gravidez e decorrem de modificações anatômicas, fisiológicas e hormonais. A atenção primária à saúde encontra-se em posição singular no reconhecimento de tais desordens. Nesse contexto, esta pesquisa tem como objetivo avaliar a qualidade do sono de gestantes em uma Unidade Básica de Saúde e correlacioná-la com parâmetros analisados durante o acompanhamento pré-natal. Metodologia: trata-se de um estudo observacional, transversal e analítico, desenvolvido por meio de pesquisa de campo, com gestantes acompanhadas em uma Unidade Básica de Saúde. Os dados foram obtidos utilizando uma ficha de questionário que associava algumas variáveis com a qualidade do sono, mensurada pelo Índice de Qualidade do sono de Pittsburgh, em sua versão brasileira (PSQI-BR). Resultados e Discussão: foram entrevistadas 83 gestantes, com 76 preenchendo os critérios de inclusão. A maioria das pacientes possuía idade inferir a 26 anos (64,4%), era multípara (59,2%), com peso inadequado (72,4%), não tinha distúrbio hipertensivo na gestação (76,3%) e estava no primeiro trimestre (40,8%). Após a aplicação do teste qui-quadrado de Pearson e a razão de chances, verificou-se que as três últimas variáveis citadas tinham relação com a qualidade do sono, apresentando significância estatística (p<0,05). Além disso, 34,2% das gestantes tinha má qualidade do sono. Conclusão: a qualidade do sono deve ser avaliada durante o acompanhamento pré-natal, visto que seu comprometimento é frequente, sobretudo diante de certos fatores de risco, e pode resultar em desfechos maternos adversos. Assim, o reconhecimento precoce possibilita melhora do prognóstico gestacional.

Accidents on federal highways in Brazil lead to social and economic impacts on the country. Data from the Federal Highway Police reveal that thousands of people lose their lives in these accidents year after year. This paper aims to examine the factors that influence the probability of death based on the occurrence of the accident. The estimation of a binary logistic regression model took place, in which the event of interest is the circumstance of death in an accident with data from 2021. Following variable selection procedures, it was possible to obtain the final model, which was later validated with data from 2022. The accuracy of the model for both 2021 and 2022 data was around 70%. Then, the odds ratio was calculated between some distinct categories, and how much of an increase in accident lethality it generates compared to the reference category. For example, in a crash, a pedestrian is 15.6 times more likely to die when compared to the driver, while a cyclist is 5.3 times more likely to die. Although most accidents have a human cause, some results show the need of public policies that can help reduce these tragedies. To explain the model, a dashboard was created in a way that the user is able to obtain the probability of death by selecting specific accident characteristics and those involved.

Chronic hepatitis C is a silent evolution disease that can lead to outcomes such as liver cirrhosis and hepatocellular carcinoma (HCC), a public health problem due to high universal morbidity. It is transmitted by single-stranded ribonucleic acid (RNA) virus, discovered in 1989 through studies of contaminated chimpanzees. Unsafe health practices, use of illegal intravenous drugs and tattoos are among the major risk factors for the transmission of this virus. Currently, it is estimated that 71 million people are infected worldwide, in Brazil, the prevalence of 0.7% indicates that 1.032.000 individuals are contaminated. With quick execution and rapid results availability, Rapid Tests (RT) facilitate epidemiological studies and early diagnosis of hepatic impairment, allowing the modification of the natural history of the disease. To evaluate the presence of Anti-HCV antibodies and epidemiological characteristics of hepatitis C in users of health services in Campina Grande-PB. A prospective cross-sectional observational study, from February 2015 to July 2018. Individuals born between 1945 and 1970 who sought health services voluntarily underwent structured questionnaires and the Bioeasy® Rapid Anti-HCV Test. A total of 385 individuals were studied, with a prevalence of Anti-HCV antibodies of 1.84% (n = 7). Of the interviewees, the majority (29.7%) were in the age group between 45 and 50 years and 67.7% were female. Intravenous illicit drug use, tattooing and male sex presented the highest statistical relevance as a risk factor in the study population. A prevalence higher than that estimated for the country was found, which highlights the need to implement strategies aimed at the early detection of virus carriers.
