The authors offer an evidence-based MEJC approach that is free, interactive with virtual breakout rooms and requires no prior learner preparation. Early indicators suggest that others navigating the COVID-19 crisis may want to implement this approach.

The role of secondary prevention therapy in patients with MINOCA remains unclear. This study aimed to evaluate the associations between secondary prevention medications and outcomes in patients with MINOCA. A total of 259 patients with MINOCA were consecutively enrolled. Basic information and medication of patients were assessed. We defined major adverse cardiovascular events as the primary end point and angina rehospitalization as the secondary end point. Logistic regression models were used to assess the correlation between treatment and outcomes. The proportion of statins, aspirin, clopidogrel, angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACEI/ARB), and β-blocker used at admission was 88.8%, 86.9%, 84.6%, 51.7%, and 61.4%, respectively. At discharge, patients with MINOCA were less likely to be released on statins, aspirin, clopidogrel, ACEI/ARB, and β-blocker. The use of secondary prevention medications was significantly lower at 2 years of follow-up with the most significant reductions being clopidogrel 29.4%, ACEI/ARB 39.0%, and aspirin 42.3%. About 19.1% of patients with MINOCA suffered adverse events during the follow-up period. Adverse events risk decreased when statins and ACEI/ARB were used, whereas the risk of adverse events was not lower in patients with aspirin, clopidogrel, and β-blocker. In conclusion, patients with MINOCA were less likely to receive secondary prevention medications at the time of discharge and early discontinuation of medications at the time of follow-up. Statins and ACEI/ARB were the only medications substantially associated with lower adverse events; by comparison, aspirin, clopidogrel, and β-blocker seem to have no impact on prognosis.

Although hospital length of stay is generally modeled continuously, it is increasingly recommended that length of stay should be considered a time-to-event outcome (i.e., time to discharge). Additionally, in-hospital mortality is a competing risk that makes it impossible for a patient to be discharged alive. We estimated the effect of trauma center accreditation on risk of being discharged alive while considering in-hospital mortality as a competing risk. We also compared these results with those from the "naive" approach, with length of stay modeled continuously.

Data include admissions to a level I trauma center in Quebec, Canada, between 2008 and 2017. We computed standardized risk of being discharged alive at specific days by combining inverse probability weighting and the Aalen-Johansen estimator of the cumulative incidence function. We estimated effect of accreditation using pre-post, interrupted time series (ITS) analyses, and the "naive" approach.

Among 5,300 admissions, 12% died, and 83% were discharged alive within 60 days. Following accreditation, we observed increases in risk of discharge between the 7th day (4.5% [95% CI = 2.3, 6.6]) and 30th day since admission 3.8% (95% CI = 1.5, 6.2). We also observed a stable decrease in hospital mortality, -1.9% (95% CI = -3.6, -0.11) at the 14th day. Although pre-post and ITS produced similar results, we observed contradictory associations with the naive approach.

Treating length of stay as time to discharge allows for estimation of risk of being discharged alive at specific days after admission while accounting for competing risk of death.

Lifecourse research provides an important framework for chronic disease epidemiology. However, data collection to observe health characteristics over long periods is vulnerable to systematic error and statistical bias. We present a multiple-bias analysis using real-world data to estimate associations between excessive gestational weight gain and mid-life obesity, accounting for confounding, selection, and misclassification biases.

Participants were from the multiethnic Study of Women's Health Across the Nation. Obesity was defined by waist circumference measured in 1996-1997 when women were age 42-53. Gestational weight gain was measured retrospectively by self-recall and was missing for over 40% of participants. We estimated relative risk (RR) and 95% confidence intervals (CI) of obesity at mid-life for presence versus absence of excessive gestational weight gain in any pregnancy. We imputed missing data via multiple imputation and used weighted regression to account for misclassification.

Among the 2,339 women in this analysis, 937 (40%) experienced obesity in mid-life. In complete case analysis, women with excessive gestational weight gain had an estimated 39% greater risk of obesity (RR = 1.4, CI = 1.1, 1.7), covariate-adjusted. Temsirolimus Imputing data, then weighting estimates at the guidepost values of sensitivity = 80% and specificity = 75%, increased the RR (95% CI) for obesity to 2.3 (2.0, 2.6). Only models assuming a 20-point difference in specificity between those with and without obesity decreased the RR.

The inference of a positive association between excessive gestational weight gain and mid-life obesity is robust to methods accounting for selection and misclassification bias.

No study to our knowledge has examined the use of observational data to emulate a clinical trial whereby patients at the time of kidney transplant proposal are randomly assigned to an awaiting transplantation or transplantation group. The main methodologic issue is definition of the baseline for dialyzed patients assigned to awaiting transplantation, resulting in the inability to use common propensity score-based approaches. We aimed to use time-dependent propensity score to better appraise the benefit of transplantation.

We studied 23,231 patients included in the French registry and on a transplant waiting list from 2005 to 2016. The main outcome was time to death. By matching on time-dependent propensity score, we obtained 10,646 pairs of recipients (transplantation group) versus comparable patients remaining on dialysis (awaiting transplantation group).

The baseline exposure, that is, pseudo-randomization, was matching time. Median follow-up time was 3.5 years. At 10 years' follow-up, the restricted mean survival time was 8.
