Observational Study
Prognosis Impact of Frailty Assessed by the Edmonton Frail Scale in the Setting of Acute Coronary Syndrome in the Elderly.
Elderly patients represent a large proportion of patients admitted for acute coronary syndrome (ACS). Whether frailty-defined as a biological syndrome that reflects a state of decreased physiological reserve and vulnerability to stressors-may impact the clinical outcomes in this population remains unclear. We aimed to determine the prevalence of frailty and its impact on mortality in patients aged ≥ 80 years admitted for ACS. ⋯ Frailty is a strong and independent prognostic factor for midterm all-cause mortality in elderly patients presenting with ACS.

Consensus regarding the management of massive pulmonary embolism (PE) and persistent shock after thrombolysis is lacking. A 30-year-old man collapsed with massive PE 3 days after an exploratory laparotomy for penetrating trauma, and he remained hypoxic and hypotensive despite thrombolytic therapy. ⋯ After 48 hours, the RVAD was removed, and the patient survived to discharge. ECMO and temporary RVAD to support surgical embolectomy are lifesaving therapeutic considerations.

Review Meta Analysis
Risk Prediction Models for Contrast-Induced Acute Kidney Injury Accompanying Cardiac Catheterization: Systematic Review and Meta-analysis.
Identification of patients at risk of contrast-induced acute kidney injury (CI-AKI) is valuable for targeted prevention strategies accompanying cardiac catheterization. ⋯ Three published models were identified that produced generalizable risk estimates for predicting CI-AKI. Further research is needed to evaluate the effect of their implementation in clinical care.

Review Meta Analysis
Warfarin and the Risk of Stroke and Bleeding in Patients With Atrial Fibrillation Receiving Dialysis: A Systematic Review and Meta-analysis.
Patients with atrial fibrillation who receive dialysis are at a high risk of ischemic stroke. The role of warfarin in mitigating this risk in patients with atrial fibrillation who receive dialysis is uncertain. Our objective was to examine the safety and efficacy of warfarin in patients who have atrial fibrillation and receive dialysis. ⋯ Observational studies suggest that warfarin was not associated with a clear benefit or harm among patients who have atrial fibrillation and receive dialysis. These estimates were limited by study heterogeneity including the inability to account for a number of important confounders such as the time in the therapeutic range. Because of the high prevalence of atrial fibrillation, stroke, and bleeding complications in this population, well designed clinical trials of warfarin and other anticoagulants are urgently needed.

Research is a core aspect of training in academic medicine, but fellows face many challenges thwarting their ability to perform clinically meaningful projects. The concept of a multicentre clinical trial collectively operated by fellows, and integrated longitudinally into training, has never been described. In this article, the authors expose the key principles of Collectively Operated Fellow-Initiated Research (COFIR) that they put in place. ⋯ Third, fellows must document and disseminate the newly acquired methodological know-how. Finally, fellows must put the safety of patients above any other consideration. Examples of how these principles were applied in a research project are provided in this article; it represents a call to action for fellows to collectively contribute to the production of significant medical research.
