False Elevation of Troponin Levels in a Patient With Chest Pain and Significant Psychoemotional Stress.

We present a case of a 63-year-old woman who experienced significant psychoemotional stress and was seen in the emergency department for an evaluation of chest pain. She was sent home after reassurance. Subsequent troponin levels came back above the normal range.

Cohort study on immune checkpoint inhibitor-associated acute kidney injury: Incidence, risk factors, and management strategies.

Introduction: Case studies and retrospective chart reviews of health system data have demonstrated an increased risk of nephrotoxicity in patients receiving immune checkpoint inhibitors compared to clinical trials. This study investigated the frequency, causes, and risk factors for acute kidney injury in a real-world, rural setting.

Methods: This was a retrospective cohort study of patients who received at least one dose of a checkpoint inhibitor at a rural health system from May 2013 to February 2020 and who received at least one dose of a checkpoint inhibitor.

Three-Year Survival after Transcatheter Aortic Valve Replacement: Findings from the Marshfield Aortic Valve Experience (MAVE) Study.

Transcatheter aortic valve replacement (TAVR) is a rapidly evolving treatment for severe aortic stenosis. However, uncertainties exist for optimal valve selection as there are few long-term studies comparing patient survival by valve type. We hypothesized that self-expandable valves (SEV) would provide a survival advantage over balloon expandable valves (BEV), as SEV continue to expand and might better accommodate to the anatomy of the aortic valve over time.
