Characteristics and survival of hospitalized combat casualties during two major conflicts between Israel and Hamas: 2023 versus 2014.

Background: In the complex landscape of modern warfare, understanding combat-related injuries leading to hospitalization is crucial for optimizing injury treatment. This study aims to compare combat casualty characteristics and outcomes during the major conflicts between Israel and Hamas in 2023 and 2014 as a basis for understanding the effectiveness of trauma care practices for wounded soldiers.

Methods: A cohort study of soldiers hospitalized due to combat injuries during two major wars between Israel and Hamas in 2023 and 2014, using data from the Israeli National Trauma Registry.

Impact of Atrial Fibrillation Type on Outcomes of Transcatheter Aortic Valve Replacement for Aortic Stenosis: A Single-Center Analysis.

Background: Atrial fibrillation (AF) is a recognized risk factor for mortality after transcatheter aortic valve replacement for severe aortic stenosis, but the impact of different types of AF on clinical outcomes remains unclear.

Methods: This retrospective study included 982 patients divided into 3 groups: no AF, paroxysmal AF, and nonparoxysmal AF (persistent or permanent). Clinical outcomes were analyzed using inverse probability weighting and multivariate models.

Validation of Parkinson's Disease Ascertainment in the Veterans Administration Electronic Medical Record.

Background: Electronic medical record (EMR)-based studies hold great potential for epidemiologic investigations of Parkinson's disease (PD) causal factors and phenomenology, but diagnostic misclassification may obscure or bias inferences.

Objectives: The aims were to determine the validity of PD diagnostic codes in the Veterans Administration (VA) national electronic medical databases and develop recommendations for maximizing ascertainment accuracy.

Methods: We investigated a cohort of 146,776 veterans who utilized VA healthcare between 1999 and 2021.

Early crystalloid resuscitation in Trauma: How much is too much? Insights from a National Trauma Registry.

Background: Crystalloid administration during early resuscitation of bleeding trauma patients is recommended by current guidelines, yet evidence supporting this practice is limited. We aimed to evaluate the trends in the utilization of crystalloids during the last decade and to determine the threshold crystalloid volume independently associated with mortality risk in trauma patients at risk of or experiencing shock.

Methods: A retrospective cohort study using data from the Israel National Trauma Registry (January 2013 to December 2022) was conducted.

Impact of Flow-Gradient Patterns on Outcomes of Transcatheter Aortic Valve Replacement for Severe Aortic Stenosis with Preserved Left Ventricular Ejection Fraction.

To compare the clinical outcomes of transcatheter aortic valve replacement (TAVR) in patients with severe aortic stenosis (AS) and preserved ejection fraction (pEF) according to flow-gradient status.This retrospective study focused on patients with severe AS and pEF (≥ 50%) undergoing TAVR with newer generation valves (Sapien3/3 Ultra, Evolut Pro/Pro+/FX) between 2018 and 2022 (n = 781). Patients were divided into 3 groups: normal-flow high-gradient (NF-HG, stroke volume index ≥ 35 mL/m and mean pressure gradient ≥ 40 mmHg or peak velocity ≥ 4 m/second), low-flow high-gradient (LF-HG), and paradoxical low-flow low-gradient (pLF-LG) groups.
