Objective: To analyze the prevalence and factors associated with sexual violence against children and adolescents in the city of Petrolina/Pernambuco., Method: Ecological study carried out with data from children and adolescents who were victims of sexual violence, collected in the Information System for Notifiable Diseases and analyzed according to descriptive and inferential statistics, with multiple logistic regression., Results: A total of 1,232 cases of sexual violence against children and adolescents were registered, with a prevalence of 30.6%. Sexual violence was more likely to occur among female victims (Odds Ratio = 11.39), in their own home (Odds Ratio = 1.96), and the father was the most likely aggressor (Odds Ratio = 8.97). Alcohol use by the aggressor increased the chance for the outcome (Odds Ratio = 2.26)., Conclusion: The prevalence of sexual violence and associated factors point to the need to implement humane practices within a network of health services integrated with other public systems, with the objective of promoting, protecting and defending the rights of children and adolescents.

Objective: To evaluate the clinical evolution and survival of neurocritical patients in Hospital Units., Method: Cohort with hospitalized patients in follow-up treatment in public and private hospitals between September 2012 and June 2016. Data were initially analyzed from descriptive and inferential statistics. The Kaplan-Meier indicator was applied as a form of survival analysis. The Cox proportional hazards regression model was used to analyze the prognostic factors by calculating the hazard ratio., Results: Participation of 1,289 patients in the study. Patients with a higher score on the Glasgow Coma Scale presented greater survival, and the one-point increase in the scale score corresponded to 42% improvement in their survival. In the analysis of survival, sex and the use of vasoactive drugs showed a significant difference., Conclusion: Female patients with a better score on the Glasgow Coma Scale and using vasoactive drugs had higher survival rates.
