Background: In ST-segment elevation myocardial infarction, the main therapy is early arterial reperfusion, performed by primary percutaneous coronary intervention. The recommended door-to-balloon time is <90 minutes. The objective of this study was to associate the door-to-balloon time and clinical factors with hospital shifts. Methods: This was a cross-sectional observational study, part of the Catarina Heart Study. We analyzed patients diagnosed with ST-segment elevation myocardial infarction in hospitals of the metropolitan area of Florianópolis, from 2016 to 2020. The qualitative variables were analyzed using the Chi-square test, and the quantitative variables were analyzed using the Student’s t test and Mann-Whitney test. Results: A total of 318 patients were analyzed, with a mean age of 58.7±11.4 years, predominantly male (71.7%) and hypertensive (53.7%). The median door-to-balloon time was significantly lower in the group seen on weekdays compared to the group seen on weekends, respectively, 71.0 (51.0-126.0) minutes and 91.0 (71.0-123.0) minutes (p=0.028). There was no difference in the door-to-balloon time in the night shift and in off-hours. Individuals undergoing primary percutaneous coronary intervention during the night shift showed a non-significant tendency for higher mortality rates from any cause (1.9%) compared to those seen during the day shift (0.0%; p=0.057). Conclusion: Patients with ST-segment elevation myocardial infarction seen on weekdays have shorter door-to-balloon time.

Objective: To investigate factors associated with pregnancy in adolescent couples and the perinatal outcomes. Method:A cross-sectional study with SINASC/SC data, included 17,156 deliveries of primiparous women with single pregnancy. Prevalence ratios adjusted according to hierarchical model and Percentage Attributable Risk (RAP) were calculated to obtain the excess in the chances of the outcomes among the adolescent couples.Results: Findings show that in the 16.6% of deliveries among adolescent mothers, more than 1/3 of these occurred among live births of adolescent parents. This group had a less privileged profile regarding sociodemographic factors, prenatal care and an excess in the relative risk and attributable risk for practically all the variables of interest when compared to pairs of adolescent mother and adult father. Conclusion:When strategies are designed directed at the issue of adolescent pregnancy, it is essential to look at the adolescent couple as a special group, and the adolescent father as an independent factor, with an important role in the final definition of risk in this group.

Materials and Methods:A cross-sectional study was carried out using data from the National School Health Survey (PeNSE), for the year of 2015. Female adolescents from 13 to 17 years of age were included. The dependent variable was pregnancy. The data were analyzed using SPSS 18.0, Chi-square test was applied and prevalence ratios (PR), with 95% CI were obtained, results were considered statistically significant when p value was less than 5%. A model of Multivariate Analysis by Logistic Regression was used, based on a Hierarchical Model.
