Gender-Specific Patterns of Injury in Older Adults After a Fall from a Four-Wheeled Walker (Rollator): Retrospective Study from a Swiss Level 1 Trauma Centre.

Aim: As the population is aging, falls by older people, in particular falls from four-wheeled walkers ("rollators"), are a growing problem. These falls must be examined by targeted research and interventions that incorporate gender differences. Therefore, this study examined the injury patterns of elderly patients admitted to a tertiary trauma centre in Switzerland after falls from rollators and focussed on gender differences.

Pre-injury narcotic drug use in isolated severe traumatic brain injury: effect on outcomes.

Purpose: The aim of this study was to explore the association between pre-injury narcotic drug use (opioids, methadone, and/or oxycodone) and outcomes in isolated severe traumatic brain injury (TBI) patients.

Methods: ACS TQIP study included adult trauma patients (≥ 16 years) with complete drug and alcohol screening. Isolated severe TBI was defined as head trauma with AIS 3-5 and without significant extracranial trauma.

Early Restrictive vs Liberal Oxygen for Trauma Patients: The TRAUMOX2 Randomized Clinical Trial.

Importance: Early administration of supplemental oxygen for all severely injured trauma patients is recommended, but liberal oxygen treatment has been associated with increased risk of death and respiratory complications.

Objective: To determine whether an early 8-hour restrictive oxygen strategy compared with a liberal oxygen strategy in adult trauma patients would reduce death and/or major respiratory complications.

Design, Setting, And Participants: This randomized controlled trial enrolled adult trauma patients transferred directly to hospitals, triggering a full trauma team activation with an anticipated hospital stay of a minimum of 24 hours from December 7, 2021, to September 12, 2023.

Surgical Management of Penetrating Carotid Artery Injury: Preoperative Level of Consciousness Does Matter.

Background: The optimal surgical management of penetrating carotid artery injuries (PCAIs) remains controversial. This study aimed to examine the association between operative techniques for PCAI and the incidence of stroke.

Study Design: This retrospective cohort study used the American College of Surgeons TQIP (2016 to 2021) database.

Understanding AFM-IR Signal Dependence on Sample Thickness and Laser Excitation: Experimental and Theoretical Insights.

Photothermal induced resonance (PTIR), also known as atomic force microscopy-infrared (AFM-IR), enables nanoscale IR absorption spectroscopy by transducing the local photothermal expansion and contraction of a sample with the tip of an atomic force microscope. PTIR spectra enable material identification at the nanoscale and can measure sample composition at depths >1 μm. However, implementation of quantitative, multivariate, nanoscale IR analysis requires an improved understanding of PTIR signal transduction and of the intensity dependence on sample characteristics and measurement parameters.
