Epidemiological profile, temporal analysis, and future projections of suicide cases in rural cities in the extreme south of Brazil.

The present study aimed to verify the time series (2000-2017) of death rates by suicide and its associated factors in 4 municipalities in the extreme south of Brazil. Data were obtained through the analysis of medical reports and police report bulletins at the Instituto Médico Legal, in the city of Rio Grande. The suicide rate in the Rio Grande region varied from 4 to 11 suicides per 100,000 inhabitants and it is estimated that by 2030 this rate could reach 16.5 suicides per 100,000 inhabitants. The rural cities of Santa Vitória do Palmar and Chuí present even higher suicide averages when compared to Rio Grande, the most populous city of the four. The death rate from suicide increased gradually in the period analyzed, with the prevalence rising among the youngest and the elderly population. A more comprehensive understanding of the influences of environmental issues on suicidal decisions constitutes an important action that needs to be taken, both because of regional vulnerabilities and the target population identified. Evidence indicates that knowledge of factors affecting individuals residing in this Brazilian region where increased suicide rates are recorded needs to be recognized as a priority.

Impact of hepatitis C virus eradication with direct-acting antivirals on glycidic metabolism.

Objective: To compare the glucose metabolism of patients with chronic hepatitis C virus infection treated with direct-acting antivirals (DAAs) in pretreatment and sustained viral response (SVR) periods. Materials and methods: This was an intervention pre-post study of 273 patients with chronic hepatitis C virus infection treated with DAAs from March 2018 to December 2019. Glycidic metabolism was evaluated through homeostasis model assessment (HOMA) - insulin resistance (IR) and HOMA-ß indices and assessments of insulinemia and HbA1c levels. These parameters were analyzed with a T test by paired comparison of the means of the variables and Wilcoxon's test paired for the median; in the variables with an abnormal distribution, the Z score was generated for the mean in both the pretreatment and SVR periods. Statistical significance was considered at p ≤ 0.05. Results: Among 273 participants, 125 (45.8%) had prediabetes, and 50 (18.3%) had diabetes. In SVR, there was a significant increase in platelets, albumin, alkaline phosphatase, cholesterol and triglycerides and a significant decrease in aspartate aminotransferase, alanine aminotransferase, gamma GT and bilirubin. The HOMA-IR and HOMA-ß indices increased in SVR from 1.95 to 2.29 (p = 0.087) and 71.20 to 82.60 (p = 0.001), respectively. Insulinemia increased from 7.60 µU/mL to 8.90 µU/mL (p = 0.011). HbA1c decreased from 5.6 to 5.4 (p < 0.001). Among patients with prediabetes and those with diabetes, the reduction in HbA1c values was significant (p = 0.006 and p = 0.026, respectively). Conclusion: SVR significantly impacts and leads to improvement in glucose metabolism in patients with chronic liver disease induced by hepatitis C virus.

Cut down on the prevalence of cesarean sections in Brazil: a time-series from 2000 to 2017

Cesarean section was developed to reduce maternal-fetal morbidity and mortality, however when performed without scientific evidence it is associated with complications. This study analyses the temporal trend and factors associated with cesarean section in Brazil, its regions and Federation Units between 2000 and 2017. Ecological study. The prevalence of cesarean sections and maternal variables were identified from the Information System on Live Births. The Prais-Winsten method was used for time series analysis. In the whole period there were 53.497.303 births in Brazil, 48.4% by cesarean section. Between 2000 and 2009, the mean cesarean section in Brazil increased from 39.7% (SD 9.8) to 53% (SD 9.4) between 2010 and 2017 with an annual variation of 1.7 p.p (95%CI 1.6; 1.8). There is stability between 2010 and 2017, with a slight decline from 2015 in the Southeast region with an annual variation of -0.9 (95%CI -1.5; 0.0). It is observed that the caesarean section has remained stable in most macro-regions and even decreasing in the southeast and in the group of women with higher education, not adolescents and better prenatal coverage. It is believed that Brazil has reached the plateau in the prevalence of cesarean section (60%) in most states and in the next years there is a decrease in these prevalences.
