Subarachnoid hemorrhage (SAH) is a severe cerebrovascular disorder characterized by the sudden influx of blood into the subarachnoid space. The use of sedatives may be associated with the prognosis of SAH patients. We obtained SAH data from the MIMIC-IV database. The receiver operating characteristic curve, Delong test, and decision curve analysis were used to assess the predictive value of sedatives. Propensity score matching (PSM) method was applied to match samples at a 1:1 ratio. Logistic regression analysis, generalized linear regression analysis, and stratified analysis were used to investigate the association of the sedative with in-hospital mortality and length of hospital stay (LOS). Finally, a competing risk analysis was performed to evaluate the survival probability with two potential outcomes. Dexmedetomidine had a better prognosis value than Propofol and Midazolam. After PSM analysis, the Dexmedetomidine and the non-Dexmedetomidine groups had 248 samples each. The application of Dexmedetomidine reduced the risk of in-hospital mortality but might prolong the LOS. When considering in-hospital mortality as a competing risk factor for LOS, Dexmedetomidine was a protective factor for in-hospital mortality but had no significant relationship with LOS. In conclusion, treatment of Dexmedetomidine could reduce the risk of in-hospital mortality with satisfactory predictive efficiency.

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.
Evolving racial/ethnic disparities in AML survival in the novel therapy era.

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).

Department of Emergency Medicine, The Ohio State University, Columbus.
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
February 2025
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.
