Stimulant-involved overdose deaths: Constructing dynamic hypotheses.

Int J Drug Policy

January 2025

MGH Institute for Technology Assessment, Harvard Medical School, Boston, MA, 02144, USA. Electronic address:

The overdose epidemic in the United States is evolving, with a rise in stimulant (cocaine and/or methamphetamine)-only and opioid and stimulant-involved overdose deaths for reasons that remain unclear. We conducted interviews and group model building workshops in Massachusetts and South Dakota. Building on these data and extant research, we identified six dynamic hypotheses, explaining changes in stimulant-involved overdose trends, visualized using causal loop diagrams.

Effect of Esketamine on Cognitive Recovery After Propofol Sedation for Outpatient Colonoscopy: A Randomized Clinical Trial.

Drug Des Devel Ther

January 2025

Department of Anesthesiology, Shengli Clinical Medical College of Fujian Medical University, Fujian Provincial Hospital, Fuzhou, Fujian, People's Republic of China.

Purpose: While esketamine shows promise as an adjunct in procedural sedation, its impact on postoperative cognitive recovery remains incompletely characterized. This study investigated the effects of esketamine on multiple dimensions of recovery, particularly cognition, in patients undergoing colonoscopy with propofol-based sedation.

Patients And Methods: We conducted this randomized, double-blinded, placebo-controlled trial from January 6, 2023, to May 20, 2024, at two hospitals in China.

Most cases of patellar dislocation can be reduced spontaneously or manually without sedation. To date, only one case of arthroscopic reduction for a lateral locked patellar dislocation has been reported, with a short follow-up period. Herein, we report the case of a 22-year-old man with a lateral locked patellar dislocation for whom we performed arthroscopic reduction and repair of the medial structure, which stabilized the patella medially.

Virtual reality for reduction of intraprocedural pharmacological sedation and analgesia in adult patients: A systematic review and meta-analysis.

Anaesth Crit Care Pain Med

January 2025

Department of Anesthesiology and Pain Medicine, Maisonneuve-Rosemont Hospital, Montréal, QC, Canada; Université de Montréal, Montréal, QC, Canada; Maisonneuve-Rosemont Hospital Research Center, Montreal, QC, Canada.

Background: Pharmacological sedation and analgesia are used to alleviate discomfort during awake medical procedures but can cause adverse effects like apnea and hypoxemia, increasing the need for airway management and prolonging recovery. Virtual reality (VR) has emerged as a non-pharmacological intervention to reduce the need for procedural sedatives and analgesics.

Methods: A systematic review and meta-analysis were conducted, assessing the impact of VR immersion on intraprocedural sedation and analgesia usage in adults (≥ 18 years).

Tracheostomy Practice in the Italian Intensive Care Units: A Point-Prevalence Survey.

Medicina (Kaunas)

January 2025

Department of Surgical Sciences and Integrated Diagnostics (DISC), University of Genoa, 16126 Genova, Italy.

: A tracheostomy is a frequently performed surgical intervention in intensive care units (ICUs) for patients requiring prolonged mechanical ventilation. This procedure can offer significant benefits, including reduced sedation requirements, improved patient comfort, and enhanced airway management. However, it is also associated with various risks, and the absence of standardized clinical guidelines complicates its implementation.
