Background: The role of beta-blockers in severe, traumatic brain injury (TBI) management is debated. Severe TBI may elicit a surge of catecholamines, which has been associated with increased morbidity and mortality. We hypothesize administering propranolol, a non-selective beta-blocker, within 48 h of TBI will reduce patient mortality within 30 days of injury.

Objective: To evaluate the impact of adding epidural dexmedetomidine to low-concentration patient-controlled epidural analgesia (PCEA) on pain control and side effects in total knee arthroplasty (TKA).
Methods: In this double-blind study, American Society of Anesthesiologists I to II patients undergoing TKA were assigned to receive 0.125% bupivacaine + fentanyl 4 µg/mL (group R) or 0.

Background: Afatinib and Osimertinib are first-line treatments for EGFR-mutated advanced non-small cell lung cancer (NSCLC), but their comparative efficacies and the patient groups that benefit the most remain unclear. This multicenter retrospective study evaluated the efficacy of first-line Afatinib and Osimertinib in NSCLC patients with EGFR 19del and no brain metastases at diagnosis.
Methods: The primary endpoints were time on treatment (ToT) and overall survival (OS).

This study investigates the modulatory effects of nicergoline, a major bioactive compound derived from ergot fungus, on the 5-hydroxytryptamine 3A (5-HT3A) receptor. Utilizing a two-electrode voltage-clamp technique, we evaluated the impact of nicergoline on the 5-HT-induced inward current (I) in 5-HT3A receptors. Our findings reveal that nicergoline inhibits I in a reversible and concentration-dependent manner.
