Introdução: a quarentena, imposta a partir de 24 de março de 2020 em São Paulo, devido à pandemia de Covid-19 trouxe problemas sociais e econômicos que contribuíram para a elevação de risco de transtornos mentais, incluindo a autolesão suicida. Objetivo: comparar as taxas de internações e de óbitos por suicídio no estado de São Paulo antes e durante a pandemia de Covid-19, correlacionando os resultados com variáveis sociodemográficas de sexo, faixa etária e cor da pele/raça das vítimas. Método: estudo descritivo com dados de morbidade hospitalar do SUS (SIH/SUS) por causas externas e por local de internação, referentes ao estado de São Paulo, nos meses de abril a dezembro, nos anos de 2017 a 2020 (CID 10 – X60 a X84). Foram estabelecidos dois grupos: pré-pandemia (2017 a 2019); e pós-pandemia (2020). Foi feita análise dos dados com o programa estatístico SPSS® Version 22.2. Resultados: foram analisados dados de 9.930 internações e 416 óbitos por lesões autoprovocadas voluntariamente. A média de internações foi maior no período pré-pandemia (278 por mês) em comparação com o da pandemia (230,5 por mês) (t(34)= 2,630; p=0,013); a média de mortes no período da pandemia foi maior (14,50 por mês) (t(34)= -3,104; p=0,004) que no pré-pandemia (11 por mês). Não houve diferença entre os períodos estudados ao correlacionar internações com dados sociodemográficos (sexo: p=0,661; faixa etária: p=0,658; cor de pele: p=0,913) ou óbitos com dados sociodemográficos (sexo: p=0,861; faixa etária: p=0,663; cor de pele: p=0,761). Conclusão: os resultados mostraram redução na média de internações por lesões autoprovocadas voluntariamente entre os períodos pré e pós-pandemia, entretanto, a média de óbitos por suicídio foi superior no período de pandemia. Isso pode significar maior efetividade da autolesão suicida durante a pandemia. Não houve diferença entre os períodos estudados ao correlacionar óbitos e internações com dados sociodemográficos.

Design of the Study: Historical Cohort. Objectives: This study aimed to verify which risk factors contribute to increase hs-cTnI in patients with Myocardial Infarcion with ST segment elevation, to ana-lyze which prognostic impacts it may have and to evaluate troponin levels in pa-tients that had previous acute myocardial infarction and assess how this com-pared to patients without previous history of an acute event. Methodology: It was assessed medical records of patients admitted in the Cor-onary Unit of the Hospital de Clínicas (HC-UFPR) in Curitiba, South of Brazil, diagnosed with ST segment elevation Myocardial Infarction and whose serum levels of high sensitivity troponin I (hs-cTnI) were collected at admission moment. The select data were: gender, age, high blood pressure, smoking, diabetes, previous myocardial infarction, dyslipidemia and serum levels of high sensitivity troponin I. For prognostic proposes, it was analysed intra-hospital death and ventricular function, based on left ventricular ejection fraction. Findings: Patients admitted with previous myocardial infarction had lower levels of hs-TnI. Gender, age, presence of high blood pressure, tabagism, diabetes and dyslipidemia didn’t reveal correlation with troponin values, allowing the in-ference that high sensitivity troponin values at first presentation of these patients have no direct relation to these variables. Regarding prognosis, levels of high sensitivity troponin could not be associated to mortality or ventricular malfunction. Conclusions: At admission, high-sensitivity troponin I levels were lower in pa-tients with prior myocardial infarction. Relevance: This work correlates the values of the high-sensitivity troponin of    patients with ST segment Elevation Myocardial Infarction to cardiovascular risks factors and to the prognosis of these patients. This approach is not found in cur-rent medical literature, whose works mainly relates to acute events.

introduction: In the early 1970s, a new type of firearm was introduced into the military arsenal, with a format and function identical to those that had been used for centuries by forces from different countries, but now fed with rubber or plastic ammunition, whose use was intended to contain the targets without causing lethal damage. Until the present-day firearms with less lethal projectiles are used by police forces. objectives: This article aims to expose the characteristics of the injuries caused by this type of ammunition, which parts of the body are most affected, in addition to finding out which are the most frequent sequelae and whether there is a risk of death in its use. methods: A literature review was performed on PubMed and all articles and case reports involving injuries in live humans caused by this type of ammunition were analyzed. results: 37 articles were included in the present study and, together, they exposed a total of 932 injuries, of which 612 could be classified as simple blunt or perforated contusion. discussion: Shots by less-lethal ammunition, despite being known as “non-lethal ammunition”, can result in death or serious impairment by damaging organs, sense or function, especially when they reach more sensitive regions of the human body, such as the face or eyes. conclusion: Of the injuries that could be classified, 60% were blunt and 40% perforated-contuse. The head was the most affected region. The eyes accounted for 32% of the total number of injuries, which justifies visual loss as the most frequently reported sequelae. The risk of death exists; 26 people died from gunshot wounds.
