Background: Risky sexual behaviors are associated with the number of sexual partners, and non-use of condom, among other factors. Objective: To identify the profile of health students attending a higher education institution, according to demographic and sexual characteristics. Methods: This is a prospective, cross-sectional and descriptive study with a quantitative approach using a sample of 819 university health students. We used a questionnaire in order to obtain information on the students' demographic characteristics, sexual behaviors and knowledge of STIs/AIDS. We defined risky behavior as the adoption of 2 or more of the following sexual behaviors: non-use of condom, more than 10 sexual partners, sexual intercourse under the influence of alcohol/drugs, and sexual intercourse with little or recently known person. Results: The sample was composed of 77.41% (634) of women and 22.59% (185) of men, with a mean age of 24.4 years (SD ± 6.7). Most participants (52%) reported risky behaviors and insufficient knowledge of STIs. Conclusion: The fact that 52% of the participants reported risky sexual behaviors points to the need for preventive interventions among this population, aimed at raising awareness and reducing the risk of STIs.

Introdução: As metástases cerebrais são, geralmente, decorrentes de carcinoma pulmonar, mama e melanoma. A procura ao hospital por sintomas neurológicos sem o conhecimento prévio do câncer primário é frequente. Objetivos: Analisar o perfil epidemiológico dos pacientes com metástase cerebral. Método: Trata-se de um estudo transversal, com coleta de dados dos pacientes com metástases cerebrais entre 2010 a 2020. Resultados: A amostra foi de 114 pacientes e os principais sítios primários foram pulmão (39%), sítio não determinado (25%) e melanoma (15%). A maior parte (61%) desconhecia o câncer primário. O local mais acometido foi lobo frontal (32%), do lado direito (41%), e a maioria das lesões eram únicas (68%). Conclusão: A análise epidemiológica corroborou com grande parte dos achados na literatura, sendo o sítio primário pulmonar e a descoberta da metástase antes do câncer primário a maioria dos casos.

Objectives: to evaluate the profile of emergency care of trauma patients at Hospital Universitário Evangélico Mackenzie (HUEM) during the period of restrictive measures due to COVID-19 (03/13/2021 to 04/05/2021), and compare to the same period at the beginning of the pandemic, in 2020, and before the pandemic, in 2019. Methods: quantitative and descriptive observational cross-sectional study. The final sample of 8,338 was analyzed in terms of date, gender, age and service responsible for providing care; the traumas were analyzed according to the etiology and conduct of the treatment and outcome. Results: there was a percentage increase in non-traumatic emergency care during the pandemic, and the medical clinic held a third of admissions in 2021. There was a reduction in trauma care, since in 2019 traumas were responsible for 44.9% of admissions and by 23.5% in 2021. There was a significant difference in the proportion between the attendance of men and women, and the percentage of men victims of trauma was higher than in the pre-pandemic periods. There was a reduction in absolute numbers, with statistical significance, in traffic accidents, falls from the same level, burns, general blunt trauma and sports and leisure trauma. The proportion of conservative treatments with hospital discharge reduced. There was a significant difference in the number of deaths, decreasing in 2020 but increasing in 2021. Conclusion: there was a reduction in trauma care during the pandemic, but the profile remained the adult male victim of a traffic accident. More severe traumas were admitted, resulting in an increase in surgical treatment, hospitalizations and deaths.
