Transtornos mentais comuns entre estudantes de medicina da Universidade Federal de Sergipe: estudo transversal

Objetivo: Estimar a prevalência de transtorno mental comum e fatores associados entre estudantes de Medicina da Universidade Federal de Sergipe. Método: Estudo transversal com 473 dos 512 matriculados em 2006, aplicando o Self Reporting Questionnaire-20 e um questionário estruturado sobre características sociodemográficas, processo ensino-aprendizagem e vivências psicoemocionais. Os calouros foram excluídos após comparação inicial com os alunos do 2° ao 12° períodos. Análise estatística por regressão logística múltipla, após estatística descritiva e cálculo das ORs simples e ajustadas. Resultados: A prevalência de transtorno mental comum geral foi de 40% (n = 473), mas com a retirada dos calouros, aumentou para 42,5% (n = 433) entre os alunos do 2° ao 12° semestre, sendo maior entre aqueles que não acreditavam ter adquirido habilidades para se tornarem bons médicos (OR = 2,82), que se sentiam pouco confortáveis com as atividades do curso (OR = 3,75), que se consideravam emocionalmente tensos (OR = 2,14), nos que não se consideravam felizes (OR = 2,85), nos que achavam que o curso era menos do que esperavam (OR = 1,64) e nos que tiveram diagnóstico prévio de transtorno mental feito por psiquiatra (OR = 3,78). Conclusão: Os resultados sugerem a necessidade de mudanças no processo ensino-aprendizagem, bem como estruturação de programas para cuidar da saúde mental dos estudantes. _________________________________________________________________________________________ ABSTRACT: Objective: Estimate the prevalence of common mental disorder and its associated factors among medical students of the Universidade Federal de Sergipe. Method: A cross-sectional study was carried out, applying Self Reporting Questionnaire-20 to 473 students from the 512 medical students enrolled in 2006 and compared with compared with a structured questionnaire by the authors containing information on the socio-demographic characteristics, the teaching–learning process and the psycho-emotional experiences of the students. Freshmen were excluded after initial comparison with the students already exposed to the medical course. Statistical analysis by multiple logistic regression after calculating simple and adjusted odds ratio (OR). Results: The general prevalence of common mental disorder was 40% (n = 473); after exclusion of the freshmen it increased to 42.5% among students from the 2nd to the 12th semester.It was higher among those who did not have faith in their acquisition of the skills needed to become a good doctor (OR = 2.82), who felt less comfortable about course activities (OR = 3.75), who considered themselves emotionally stressed (OR = 2.14), among those who did not consider themselves happy (OR = 2.85), who believed that the course did not match their expectations (OR = 1.64) and those who had a prior diagnosis of mental disorder by a psychiatrist (OR = 3.78). Conclusion: The results suggest the necessity of changes to the teaching-learning process and the establishment of a preventive mental health program for medical students

Guidelines for the use and interpretation of assays for monitoring autophagy (4th edition)1.

In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide realistic and reasonable critiques of reports that are focused on these processes. These guidelines are not meant to be a dogmatic set of rules, because the appropriateness of any assay largely depends on the question being asked and the system being used. Moreover, no individual assay is perfect for every situation, calling for the use of multiple techniques to properly monitor autophagy in each experimental setting. Finally, several core components of the autophagy machinery have been implicated in distinct autophagic processes (canonical and noncanonical autophagy), implying that genetic approaches to block autophagy should rely on targeting two or more autophagy-related genes that ideally participate in distinct steps of the pathway. Along similar lines, because multiple proteins involved in autophagy also regulate other cellular pathways including apoptosis, not all of them can be used as a specific marker for bona fide autophagic responses. Here, we critically discuss current methods of assessing autophagy and the information they can, or cannot, provide. Our ultimate goal is to encourage intellectual and technical innovation in the field

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.
