Objective: The administration of amiodarone or lidocaine is recommended during the resuscitation of out-of-hospital cardiac arrest (OHCA) patients presenting with defibrillation-refractory or recurrent ventricular fibrillation or ventricular tachycardia. Our objective was to use 'target trial emulation' methodology to compare the outcomes of patients who received amiodarone or lidocaine during resuscitation.

Methods: Adult, non-traumatic OHCA patients in the ESO Data Collaborative 2018-2023 datasets who experienced OHCA prior to EMS arrival, presented with a shockable rhythm, and received amiodarone or lidocaine during resuscitation were evaluated for inclusion.

Glucocorticosteroids remain the most common pharmaceutical approach for the treatment of equine asthma but can be associated with significant side effects, including respiratory microbiome alterations. The goal of the study was to assess the impact of 2% lidocaine nebulization, a projected alternative treatment of equine asthma, on the healthy equine respiratory microbiota. A prospective, randomized, controlled, blinded, 2-way crossover study was performed, to assess the effect of 1 mg/kg 2% lidocaine (7 treatments over 4 days) on the equine respiratory microbiota compared to control horses (saline and no treatment).

Purpose: Catheter ablation (CA) for atrial fibrillation (AF) in heart failure patients with preserved ejection fraction (HFPEF) has shown promising results in reducing mortality and improving heart function. However, previous studies have been limited by a lack of control groups and significant heterogeneity in their methodologies.

Hypothesis: CA for AF in HFPEF patients may not increase the complications and had similarly the rate of freedom from AF vs.

Background: Amiodarone is a widely used antiarrhythmic agent with significant toxicities and drug interactions more likely to affect older adults. Nevertheless, data regarding amiodarone safety in this population are limited.

Methods: We conducted a retrospective analysis of FDA Adverse Event Reporting System (FAERS) data from 2003 to 2024 .

Objectives: Lateral sagittal infraclavicular approach is frequently used because it has less risk of complications and provides rapid and adequate regional anesthesia. Due to the fact that the brachial plexus is deeper in the infraclavicular region and the approach angle is sharper, it can be technically challenging. In this study, we aimed to compare the costoclavicular approach, which is a newly defined approach, with the lateral sagittal infraclavicular brachial plexus block.
