OBJECTIVE: To evaluate the attributes of Primary Health Care (PHC) for rural workers; to analyze sociodemographic conditions, history of poisoning and hospitalizations for pesticides and use of personal protective equipment; and to verify exposure to pesticides by determining bioindicators. METHODS: Cross-sectional, descriptive-analytical study with a sample of 1,027 rural workers living in municipalities belonging to a regional health department in Southern Minas Gerais, whose PHC is governed by the Family Health Strategy model. We used the adult version of the Primary Care Assessment Tool (PCATool Brazil) and a structured questionnaire to collect socioeconomic data, history of poisoning and hospitalization for pesticides and use of personal protective equipment. Blood samples were collected to measure biomarkers of pesticide exposure and signs of renal and hepatic sequelae. RESULTS: Low education was prevalent, as well as the intense contact of workers with pesticides. Frequent use of personal protective equipment was higher among men, as was the history of poisoning and hospitalizations for pesticides. Rates of 20% poisoning, 15% liver disease and 2% nephropathy were detected. Signs of hepatotoxicity were more frequent in men. Gender differences were all statistically significant. Regarding PHC, only the attribute “degree of affiliation” had a high score. None of the poisoning cases detected in the study were previously diagnosed. CONCLUSIONS: Despite the high coverage of the Family Health Strategy, occupational risk and its consequences have not been detected by health services, which do not seem oriented to primary care, even lacking their essential attributes. There is a need for immediate and effective adaptation of public policies regarding the health of rural workers, with adequate training of teams and review of the portfolio of PHC services offered.

Introdução: Indivíduos com diabetes correm um risco maior de hospitalização e mortalidade resultante de infecções virais, bacterianas e fúngicas. A doença do coronavírus-2019 (COVID-19), causada pela síndrome respiratória aguda grave do coronavírus-2 (SARS-CoV-2), se espalhou rapidamente para os países e custou milhares de vidas até dezembro de 2020. Notavelmente, em vários estudos, o diabetes é uma das comorbidades mais relatadas em pacientes com COVID-19 grave. Objetivo: Discutir sobre a influência do diabetes sobre o prognóstico de pacientes com COVID-19 através de uma revisão literatura. Metodologia: Trata-se de um estudo de revisão sistemática. Para identificar a literatura publicada até dezembro de 2020, foram aplicadas estratégias de buscas individuais nos seguintes bancos de dados eletrônicos: PubMed, Medline, Lilacs e SciELO. Resultados: Pode-se notar que com base nos novos dados clínicos obtidos de pacientes COVID-19, vários mecanismos, como tempestade de citocinas, disfunção pulmonar e endotelial e hipercoagulação, que podem tornar os indivíduos com diabetes mais vulneráveis à COVID-19. Estudos epidemiológicos mostram que o diabetes mal controlado é um fator de risco para várias doenças infecciosas. Conclusão: Dado a importância clínica do diabetes e a natureza pandêmica dos coronavírus, compreender como o diabetes afeta a gravidade da COVID-19 é fundamental para o desenvolvimento de conscientização da população e de tratamentos personalizados de indivíduos afetados pelas doenças.

Introduction: The synthesis ovarian’s steroids is a process thats depends on the supply of cholesterol. Objective: to evaluate the influence of dyslipidemia on the secretion ovarian’s steroids. Methodology: wild female mice were used (C57BL6) and LDL (LDLR-/-), which they were separated into 4 groups (n = 10): WTS: fed a standard diet; WTHL: fed a high-fat diet; KOS: fed a standard diet; KOHL: fed a high-fat diet. After 60 days, the estrous cycle was analyzed and after anesthetized, blood was collected for the to assess the lipid profile, glucose, plasma insulin level and HOMA index was calculated. In addition, plasma levels of C-reactive protein, estrogen and progesterone were determined. Results: The hyperlipidic diet in both the WTHL and the KOHL group generated hypercholesterolemia when compared to the WTS and KOS, respectively, with a decrease in HDLc, associated with an increase in CRP levels. Severe hypercholesterolemia in the KOHL group generated insulin resistance, marked by an increase in HOMAir. Food hypercholesterolemia in the WTHL group, food and genetics in the KOHL group, compared to their WTS and KOS controls, was definitive in reducing plasma levels of estrogen and progesterone. The genetic hypercholesterolemia associated with insulin resistance observed in the KOS and KOHL groups reduced the levels of progesterone, this reduction being more severe in the KOHL group, which had the highest HOMAir. Conclusion: dyslipidemia affected ovarian steroidogenesis in mice by means of oxidative stress, inflammation and insulin resistance and / or by decreasing HDL cholesterol levels.
