A cross-sectional study comparing the shadow'' examiner with the original OSCE examiner format(2019) RODRIGUES, Marcelo Arlindo Vasconcelos; OLMOS, Rodrigo Diaz; KIRA, Celia Maria; LOTUFO, Paulo Andrade; SANTOS, Itamar Souza; TIBERIO, Iolanda de Fatima Lopes CalvoOBJECTIVES: Feedback is a powerful learning tool, but a lack of appropriate feedback is a very common complaint from learners to teachers. To improve opportunities for feedback on objective structured clinical examinations (OSCEs), a modified examiner role, termed the ""shadow'' examiner, was tested. This study aims to present and analyze comparisons between the ""shadow'' examiner and the original OSCE examiner format. METHODS: In 2011, experiments were carried out with modifications to the examiner's role to define the ""shadow'' examiner format. From February 2012 to May 2014, research was conducted with 415 6th-year medical students. Of these students, 316 were randomly assigned to assessments by both ""shadow'' and ""fixed'' examiners. Pearson correlation analysis with linear regression, Student's t-tests and Bland-Altman plots were the statistical methods used to compare the assessment modes. To strengthen the analysis, checklist items were classified by domain. RESULTS: High correlations between the ""shadow'' and ""fixed'' examiners' global scores were observed. The results of the analysis of specific domains demonstrated higher correlations for cognitive scores and lower correlations for affective scores. No statistically significant differences between the mean examiner global scores were found. The Bland-Altman analysis showed that the ""shadow'' examiners' affective scores were significantly higher than those of the ""fixed'' examiners, but the magnitude of this difference was small. CONCLUSION: The modified examiner role did not lead to any important bias in the students' scores compared with the original OSCE examiner format. This new strategy may provide important insights for formative assessments of clinical performance.

Objectives: The aim of this study was to analyze the urine cultures performed at a secondary hospital, during two periods, 2005-2006 and 2010-2011, and to estimate the microbial resistance. Patients and methods: We analyzed 11,943 aerobic urine cultures according to basic demographic data and susceptibility to antibiotics in accordance with the Clinical and Laboratory Standards Institute (CLSI) for Vitek 1 and 2. Results: Most of our cohort consisted of young adult females that were seen at the Emergency Department. E. coli was the most frequent (70.2%) among the 75 species isolated. Resistance of all isolates was = 20% for trimethoprim/sulfamethoxazole (TMP/SMX), norfloxacin, nitrofurantoin, cefazolin and nalidixic acid. Although E. coli was more susceptible (resistance = 20% for TMP/SMX and nalidixic acid) among all of the isolates, when classified by the number and percentage of antibiotic resistance. Global resistance to fluoroquinolones was approximately 12%. Risk factors for E. coli were female gender and an age less than 65 years. Men and patients older than 65 years of age, presented more resistant isolates. Extended spectrum beta-lactamases (ESBL) were identified in 173 out of 5,722 Gram-negative isolates (3.0%) between 2010 and 2011. Conclusion: E. coli was the most frequent microbe isolated in the urine cultures analyzed in this study. There was a significant evolution of bacterial resistance between the two periods studied. In particular, the rise of bacterial resistance to fluoroquinolones was concerning.

H.; LOTUFO, Paulo A.; BENSENOR, Isabela M.Background Atrial fibrillation is a predictor of poor prognosis after stroke. Aims To evaluate atrial fibrillation and all-cause and cardiovascular mortality in a stroke cohort with low socioeconomic status, taking into consideration oral anticoagulant use during 12-year follow-up. Methods All-cause mortality was analyzed by Kaplan-Meier survival curve and Cox regression models to estimate hazard ratios and 95% confidence intervals (95% CI). For specific mortality causes, cumulative incidence functions were computed. A logit link function was used to calculate odds ratios (OR) with 95% CIs. Full models were adjusted by age, sex, oral anticoagulant use (as a time-dependent variable) and cardiovascular risk factors. Results Of 1121 ischemic stroke participants, 17.8% had atrial fibrillation. Overall, 654 deaths (58.3%) were observed. Survival rate was lower (median days, interquartile range-IQR) among those with atrial fibrillation (531, IQR: 46-2039) vs. non-atrial fibrillation (1808, IQR: 334-3301), p-log rank < 0.0001). Over 12-year follow-up, previous atrial fibrillation was associated with increased mortality: all-cause (multivariable hazard ratios, 1.82; 95% CI: 1.43-2.31) and cardiovascular mortality (multivariable OR, 2.07; 95% CI: 1.36-3.14), but not stroke mortality. In the same multivariable models, oral anticoagulant use was inversely associated with all-cause mortality (oral anticoagulant time-dependent effect: multivariable hazard ratios, 0.47; 95% CI: 0.30-0.50, p = 0.002) and stroke mortality (oral anticoagulant time-dependent effect >= 6 months: multivariable OR, 0.09; 95% CI: 0.01-0.65, p-value = 0.02), but not cardiovascular mortality. Conclusions Among individuals with low socioeconomic status, atrial fibrillation was an independent predictor of poor survival, increasing all-cause and cardiovascular mortality risk. Long-term oral anticoagulant use was associated with a markedly reduced risk of all-cause and stroke mortality.
