Background: Cardiovascular disease remains a major cause of morbidity and mortality among homeless adults. Despite major advances in the management of ST elevation myocardial infarction (STEMI), limited information is available for the clinical presentation and management and outcome of STEMI among patients experiencing homelessness (PEH).
Methods: All patients presenting with STEMI between January 1, 2008 and December 31, 2017 at a PCI capable STEMI network inner city hospital comprised the study population. Baseline characteristics, homeless status and clinical outcomes were determined from hospital records. The primary outcome of in-hospital mortality was compared between PEH and nonhomeless patients using a log-binomial regression model with propensity score adjusted standardised mortality ratio weighting (SMRW).
Results: Among 2854 STEMI admissions during the study period, 75 patients (2.6%) were identified as PEH. The PEH group was younger (58 vs 63 years; P = 0.0002), predominantly male (96% vs 76%), and more likely to present with cardiogenic shock or cardiac arrest (17% vs 6%) compared with the nonhomeless group. The in-hospital mortality remained significantly higher among PEH (risk ratio 3.83, 95% confidence interval 1.27-11.60) after propensity score adjustment.
Conclusions: Despite universal health care and contemporary STEMI management, PEH presenting with STEMI experienced a 4-fold higher in-hospital mortality compared with the nonhomeless cohort. Targeted interventions are needed to improve STEMI outcomes in this high-risk group.

Measures to Prevent and Control COVID-19 in Skilled Nursing Facilities: A Scoping Review.
JAMA Health Forum
January 2025
Department of Health Policy and Management, Harvard T. H. Chan School of Public Health, Boston, Massachusetts.
Importance: Skilled nursing facilities (SNFs) experienced high mortality during the COVID-19 pandemic, leading them to adopt preventive measures to counteract viral spread. A critical appraisal of these measures is essential to support SNFs in managing future infectious disease outbreaks.
Objective: To perform a scoping review of data and evidence on the use and effectiveness of preventive measures implemented from 2020 to 2024 to prevent COVID-19 infection in SNFs in the US.

Little is known about the impact of recent advances in acute myeloid leukemia (AML) treatment on racial/ethnic disparities in survival outcomes. We performed a retrospective cohort study of patients with newly diagnosed AML using data from a nationwide electronic health record-derived deidentified database. Patients were categorized based on their diagnosis date relative to venetoclax approval, as pre-novel therapy era (Pre era; 2014-2018; n = 2998) or post-novel therapy era (Post era; 2019-2022; n = 2098).

Importance: While national guidelines recommend avoidance of hypoxia, hypotension, and hypocarbia in the prehospital care of traumatic brain injury (TBI), limited data validate the association of these adverse physiologic events with TBI outcomes.
Objective: To validate the associations of prehospital hypoxia, hypotension, and hypocarbia with TBI outcomes in a US national trauma network.
Design, Setting, And Participants: This cohort study examined data from 8 level I trauma centers and their affiliated ground and air emergency medical services (EMS) agencies in the Linking Investigations in Trauma and Emergency Services (LITES) Network from January 1, 2017, to June 30, 2021.
Corticosteroids in Cardiogenic Shock: A Retrospective Analysis of the Medical Information Mart for Intensive Care-IV Database.
Crit Care Explor

Division of Critical Care Medicine, Department of Medicine, McMaster University, Hamilton, ON, Canada.
Importance: While corticosteroid administration in septic shock has been shown to result in faster shock reversal and lower short-term mortality, the role of corticosteroids in the management of cardiogenic shock (CS) remains unexplored.
Objectives: Determine the impact of corticosteroid administration on 90-day mortality (primary outcome) in patients admitted to a critical care unit with CS.
Design, Setting, And Participants: In this retrospective cohort study, we used the critical care database of Medical Information Mart for Intensive Care-IV, and included all adult patients diagnosed with CS excluding repeated admissions, patients with adrenal insufficiency, those receiving baseline corticosteroids, and those requiring extracorporeal life support.
