Assessment of professional identity formation: a transcultural validation of the professional identity essay for brazilian portuguese.

INTRODUCTION: Professional identity formation (PIF) is recognized worldwide as an outcome of medical education grounded in the psychology of adult development and the literature on medical professionalism. However, instruments to assess and support PIF are scarce. The Professional Identity Essay (PIE) is an open-ended question assessment of PIF that elicits short narrative responses from learners and that can be analyzed to provide formative feedback and an overall stage of development. In this study, our aim was to translate and adapt the PIE to Brazilian Portuguese. METHODS: We followed a systematic procedure for the translation and cross-cultural adaptation of the instrument. A pilot study was conducted with medical students from the University of São Paulo. After providing individual formative feedback, we administered an online questionnaire to the Brazilian students to better understand the consequences of using the PIE. Content analyses of qualitative data were performed, we employ manifest content analysis, and the categories of analysis emerged from the participants' speeches. RESULTS: Students found the instrument's questions easy to interpret and self-reflective. It also gave students the opportunity to consider their PIF. The PIE was perceived as reliable and brought more awareness of the students' own processes in addition to a sense of capability to foster their own development. In the same way, the students emphasized the importance of being helped in this process. CONCLUSION: We found sufficient evidence of the validity of the PIE in terms of content, face validity, and consequences of use. The PIE enhances self-assurance in PIF through formative assessment and is sensitive to different cultures, making it a potential tool for educators.

Measurement of uncertainty tolerance revisited.

INTRODUCTION: Uncertainty tolerance (UT) is attracting increasing attention in medical education due to the numerous challenges associated with uncertainty in professional life. Inconsistencies in analysing the relationship between UT and moderators may arise from inadequate measurement methods. Most instruments were formulated before the most widely accepted framework was published. Our aim was to investigate the validity of an UT scale using an actual framework to corroborate with better and accurate instruments. METHODS: A total of 1052 students were invited. Various psychometric methods were used to explore validity of the TAMSAD scale in light of actual framework. Classic exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed. Secondly, content item classification was triangulated with exploratory graph analysis (EGA), and the new EFA, CFA, and cognitive diagnostic modelling (CDM) analysis were conducted. The reliability was calculated using Cronbach's alpha and McDonald's omega. RESULTS: A total of 694 students (65.9%) responded to the questionnaire. The reliability of the TAMSAD scale was 0.782. The initial EFA revealed no clear interpretable dimensions. The TAMSAD scale items can be classified into sources of uncertainty. The EGA has three dimensions, and the new EFA led to a 17-item TAMSAD scale with the following three dimensions: ambiguity, complexity, and probability. These dimensions lead to better adjustment fit indices in the new CFA and CDM analyses. CONCLUSION: We found evidence that the TAMSAD scale can be considered a multidimensional scale, organised in terms of sources of uncertainty.

Divergent: Age, Frailty, and Atypical Presentations of COVID-19 in Hospitalized Patients.

BACKGROUND: Although frailty has been associated with atypical manifestations of infections, little is known about COVID-19 presentations in hospitalized frail patients. We aimed to investigate the association between age, frailty, and clinical characteristics of COVID-19 in hospitalized middle-aged and older adults. METHOD: Longitudinal observational study comprising 711 patients aged ≥50 years consecutively admitted to a university hospital dedicated to COVID-19 severe cases, between March and May 2020. We reviewed electronic medical records to collect data on demographics, comorbidities, COVID-19 signs/symptoms, and laboratory findings on admission. We defined frailty using the Clinical Frailty Scale (CFS = 1-9; frail ≥5). We also documented in-hospital mortality. We used logistic regressions to explore associations between age, frailty, and COVID-19 signs/symptoms; and between typical symptoms (fever, cough, dyspnea) and mortality. RESULTS: Participants had a mean age of 66 ± 11 years, and 43% were female. Overall, 25% were frail, and 37% died. The most common COVID-19 presentations were dyspnea (79%), cough (74%), and fever (62%), but patients aged ≥65 years were less likely to have a co-occurrence of typical symptoms, both in the absence (OR = 0.56; 95% CI = 0.39-0.79) and in the presence of frailty (OR = 0.52; 95% CI = 0.34-0.81). In contrast, older age and frailty were associated with unspecific presentations, including functional decline, acute mental change, and hypotension. After adjusting for age, sex, and frailty, reporting fever was associated with lower odds of mortality (OR = 0.70; 95% CI = 0.50-0.97). CONCLUSIONS: Atypical COVID-19 presentations are common in frail and older hospitalized patients. Providers should be aware of unspecific disease manifestations during the management and follow-up of this population.

Dact1, a Wnt-Pathway Inhibitor, Mediates Human Mesangial Cell TGF-ß1-Induced Apoptosis.

Chronic kidney disease (CKD) is a worldwide public health problem that affects millions of men and women of all ages and racial groups. Loss of mesangial cells (MC) represents an early common feature in the pathogenesis of CKD. Transforming growth factor-ß1 (TGF-ß1) is a key inducer of kidney damage and triggers several pathological changes in renal cells, notably MC apoptosis. However, the mechanism of MC apoptosis induced by TGF-ß1 remains elusive. Here, we demonstrate for the first time a novel regulatory pathway in which the disheveled-binding antagonist of ß-catenin 1 (Dact1) gene is upregulated by TGF-ß1, inducing MC apoptosis. We also show that the inhibitory effect of Dact1 and TGF-ß1 on the transcriptional activation of the pro-survival Wnt pathway is the mechanism of death induction. In addition, Dact1 mRNA/protein levels are increased in kidney remnants from 5/6 nephrectomized rats and strongly correlate with TGF-ß1 expression. Together, our results point to Dact1 as a novel element controlling MC survival that is causally related to CKD progression. J. Cell. Physiol. 232: 2104-2111, 2017. © 2016 Wiley Periodicals, Inc.
