O consumo de bebida alcoólica e o binge drink entre os graduandos de Medicina de uma Universidade de Minas Gerais
RESUMO Objetivos O estudo objetivou verificar o padrão de consumo de bebidas alcoólicas e a presença do beber pesado episódico (BPE) entre os estudantes de Medicina de uma universidade do centro-oeste de Minas Gerais. Métodos Trata-se de um estudo transversal, exploratório e descritivo, realizado com 202 graduandos do curso de Medicina de uma universidade do centro-oeste de Minas Gerais. A coleta de dados foi realizada no primeiro semestre de 2015, com a utilização de um questionário sociodemográfico e do questionário Audit. O tratamento estatÃstico dos dados foi realizado com a utilização da análise bivariada, por meio do teste qui-quadrado ou do teste de Fisher e de modelos multivariados de regressão logÃstica. Resultados Observou-se que o álcool é utilizado por 76,6% dos estudantes pesquisados, e 53,7% praticavam o BPE. O consumo de bebidas alcoólicas teve associação significativa com a idade e o fato de não morar com a famÃlia e estar acima do terceiro ano de graduação. O BPE, por sua vez, esteve associado com o sexo masculino e com o fato de não morar com a famÃlia. Conclusões Este trabalho mostrou que o consumo de álcool entre os estudantes de Medicina é maior do que o da população geral e que a prática do BPE possui alta prevalência nesse grupo. Idade, não morar com a famÃlia e perÃodo mais avançado do curso foram associados a maior consumo de álcool. Ser do sexo masculino e não morar com a famÃlia se associaram a maior risco de BPE
The consumption of alcoholic beverages and the binge drink among Medicine graduating in a Minas Gerais University
<p></p><p>ABSTRACT Objectives The study had as its goal to verify the pattern of the alcoholic beverages consumption and the presence of drinking heavily snatchy (BPE) among the Medicine students of a Minas Gerais Midwest university. Methods It is about a transversal, exploratory and descriptive study, performed on 202 graduating students of the Medicine course of a Minas Gerais Midwest university. The data collet was performed on the first term of 2015, a sociodemographic questionnaire and the Audit questionnaire were used. The statistical treatment of the data was performed with the use of the bivariate analysis, through the chi-square test or by the Fisher test, and multivariate logistic regression models. Results It was noticed that the alcohol is used by 76,6% of the students surveyed, being that 53,7% practiced the drinking heavily episodic. The alcoholic beverages consumption had meaningful association with the age, not living with family and being above the 3rd year of graduation. Drinking heavily episodic had meaningful association with the males and not living with family. Conclusions This paperwork has shown that the alcohol consumption among Medicine students is bigger than among the general population and the binge drink practice has high prevalence on that group. Age, not living with the family and more advanced period of the course were associated with higher alcohol consumption. Being male and not living with the family were associated with a higher risk of BPE.</p><p></p
Clinical characteristics and outcomes of hospital-manifested COVID-19 among Brazilians
ABSTRACT: Objectives: To analyze the clinical characteristics and outcomes of admitted patients with the hospital- versus community-manifested COVID-19 and to evaluate the risk factors related to mortality in the first population. Methods: This retrospective cohort included consecutive adult patients with COVID-19, hospitalized between March and September 2020. The demographic data, clinical characteristics, and outcomes were extracted from medical records. Patients with hospital-manifested COVID-19 (study group) and those with community-manifested COVID-19 (control group) were matched by the propensity score model. Logistic regression models were used to verify the risk factors for mortality in the study group. Results: Among 7,710 hospitalized patients who had COVID-19, 7.2% developed symptoms while admitted for other reasons. Patients with hospital-manifested COVID-19 had a higher prevalence of cancer (19.2% vs 10.8%) and alcoholism (8.8% vs 2.8%) than patients with community-manifested COVID-19 and also had a higher rate of intensive care unit requirement (45.1% vs 35.2%), sepsis (23.8% vs 14.5%), and death (35.8% vs 22.5%) (P <0.05 for all). The factors independently associated with increased mortality in the study group were increasing age, male sex, number of comorbidities, and cancer. Conclusion: Hospital-manifested COVID-19 was associated with increased mortality. Increasing age, male sex, number of comorbidities, and cancer were independent predictors of mortality among those with hospital-manifested COVID-19 disease
Development and validation of the MMCD score to predict kidney replacement therapy in COVID-19 patients
Abstract Background Acute kidney injury (AKI) is frequently associated with COVID-19, and the need for kidney replacement therapy (KRT) is considered an indicator of disease severity. This study aimed to develop a prognostic score for predicting the need for KRT in hospitalised COVID-19 patients, and to assess the incidence of AKI and KRT requirement. Methods This study is part of a multicentre cohort, the Brazilian COVID-19 Registry. A total of 5212 adult COVID-19 patients were included between March/2020 and September/2020. Variable selection was performed using generalised additive models (GAM), and least absolute shrinkage and selection operator (LASSO) regression was used for score derivation. Accuracy was assessed using the area under the receiver operating characteristic curve (AUC-ROC). Results The median age of the model-derivation cohort was 59 (IQR 47–70) years, 54.5% were men, 34.3% required ICU admission, 20.9% evolved with AKI, 9.3% required KRT, and 15.1% died during hospitalisation. The temporal validation cohort had similar age, sex, ICU admission, AKI, required KRT distribution and in-hospital mortality. The geographic validation cohort had similar age and sex; however, this cohort had higher rates of ICU admission, AKI, need for KRT and in-hospital mortality. Four predictors of the need for KRT were identified using GAM: need for mechanical ventilation, male sex, higher creatinine at hospital presentation and diabetes. The MMCD score had excellent discrimination in derivation (AUROC 0.929, 95% CI 0.918–0.939) and validation (temporal AUROC 0.927, 95% CI 0.911–0.941; geographic AUROC 0.819, 95% CI 0.792–0.845) cohorts and good overall performance (Brier score: 0.057, 0.056 and 0.122, respectively). The score is implemented in a freely available online risk calculator ( https://www.mmcdscore.com/ ). Conclusions The use of the MMCD score to predict the need for KRT may assist healthcare workers in identifying hospitalised COVID-19 patients who may require more intensive monitoring, and can be useful for resource allocation
ABC-SPH risk score for in-hospital mortality in COVID-19 patients : development, external validation and comparison with other available scores
The majority of available scores to assess mortality risk of coronavirus disease 2019 (COVID-19) patients in the emergency department have high risk of bias. Therefore, this cohort aimed to develop and validate a score at hospital admission for predicting in-hospital mortality in COVID-19 patients and to compare this score with other existing ones. Consecutive patients (≥ 18 years) with confirmed COVID-19 admitted to the participating hospitals were included. Logistic regression analysis was performed to develop a prediction model for in-hospital mortality, based on the 3978 patients admitted between March-July, 2020. The model was validated in the 1054 patients admitted during August-September, as well as in an external cohort of 474 Spanish patients. Median (25-75th percentile) age of the model-derivation cohort was 60 (48-72) years, and in-hospital mortality was 20.3%. The validation cohorts had similar age distribution and in-hospital mortality. Seven significant variables were included in the risk score: age, blood urea nitrogen, number of comorbidities, C-reactive protein, SpO/FiO ratio, platelet count, and heart rate. The model had high discriminatory value (AUROC 0.844, 95% CI 0.829-0.859), which was confirmed in the Brazilian (0.859 [95% CI 0.833-0.885]) and Spanish (0.894 [95% CI 0.870-0.919]) validation cohorts, and displayed better discrimination ability than other existing scores. It is implemented in a freely available online risk calculator (https://abc2sph.com/). An easy-to-use rapid scoring system based on characteristics of COVID-19 patients commonly available at hospital presentation was designed and validated for early stratification of in-hospital mortality risk of patients with COVID-19
