A retrospective 'target trial emulation' comparing amiodarone and lidocaine for adult out-of-hospital cardiac arrest resuscitation.

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.

The association between initial defibrillation dose and outcomes following adult out-of-hospital cardiac arrest resuscitation: a retrospective, multi-agency study.

Introduction: Effective defibrillation is essential to out-of-hospital cardiac arrest (OHCA) survival. International guidelines recommend initial defibrillation energies between 120 and 360 Joules, which has led to widespread practice variation. Leveraging this natural experiment, we aimed to explore the association between initial defibrillation dose and outcome following OHCA.

Improved accuracy of delayed cerebral ischemia diagnosis with plasma nitric oxide synthase 3, nicotinamide adenine dinucleotide phosphate, and 8-iso-prostaglandin F2α.

Objective: The pathophysiology of delayed cerebral ischemia (DCI) is not fully elucidated. The lack of accurate diagnostic tools increases the probability of delayed diagnosis and timely treatment. The authors assessed the relationship of 8-iso-prostaglandin F2α (F2-IsoP) and oxidative stress biomarkers, nitric oxide synthase 3 (NOS3) and nicotinamide adenine dinucleotide phosphate (NADPH), with DCI after aneurysmal subarachnoid hemorrhage (aSAH).

Corticotropin-releasing factor-like diuretic hormone 44 and five corresponding GPCRs in Drosophila suzukii: Structural and functional characterization.

Diuretic hormones (DHs) activate corresponding G protein-coupled receptors (GPCRs), mediating the water and ion homeostasis in arthropods. There are two different DHs known to be expressed in insects, calcitonin (CT)-like DH31 and corticotropin-releasing factor (CRF)-like DH44. In this study, we identified and characterized a DH44 and five GPCR variants, DH44-R1 and DH44-R2a/b/c/d, in Drosophila suzukii (spotted-wing drosophila), causing detrimental damage to fresh and soft-skinned fruits.
