Continuous serratus anterior block for sternotomy analgesia after cardiac surgery: a single-centre feasibility study.
Br J Anaesth
January 2025
Department of Anesthesia, Pain Management & Perioperative Medicine, Dalhousie University, Halifax, NS, Canada.
Background: Moderate-to-severe pain is common after cardiac surgery, peaking during the first and second postoperative days. Several nerve blocks for sternotomy have been described; however, the optimal location for continuous catheters has not been established. This study assessed the feasibility of a larger trial evaluating the efficacy of serratus anterior plane (SAP) catheter analgesia for sternotomy pain.

Ann Vasc Surg
January 2025
Department of Medicine, King Edward Medical University Lahore.
Background And Objectives: Post-embolization syndrome (PES), characterized by pain, fever, nausea, and vomiting, is a common but non-serious adverse event following arterial embolization, negatively impacting patient satisfaction with the procedure. This study aimed to evaluate the efficacy of dexamethasone-based prophylactic therapy in preventing PES, as well as to assess the effects of its dosage and timing of administration.
Methods: A systematic search was conducted across three databases, two trial registries, and citation searches to identify relevant studies.
Intranasal oxytocin for apathy in people with frontotemporal dementia (FOXY): a multicentre, randomised, double-blind, placebo-controlled, adaptive, crossover, phase 2a/2b superiority trial.

Background: No treatments exist for apathy in people with frontotemporal dementia. Previously, in a randomised double-blind, placebo-controlled, dose-finding study, intranasal oxytocin administration in people with frontotemporal dementia improved apathy ratings on the Neuropsychiatric Inventory over 1 week and, in a randomised, double-blind, placebo-controlled, crossover study, a single dose of 72 IU oxytocin increased blood-oxygen-level-dependent signal in limbic brain regions. We aimed to determine whether longer treatment with oxytocin improves apathy in people with frontotemporal dementia.

Clin Trials
January 2025
Department of Biostatistics, University of Florida, Gainesville, FL, USA.
Introduction: The sequential parallel comparison design has emerged as a valuable tool in clinical trials with high placebo response rates. To further enhance its efficiency and effectiveness, adaptive strategies, such as sample size adjustment and allocation ratio modification can be employed.
Methods: We compared the performance of Jennison and Turnbull's method and the Promising Zone approach for sample size adjustment in a two-phase sequential parallel comparison design study.
Toward effective oxytocin interventions in autism: Overcoming challenges and harnessing opportunities.
J Psychopharmacol
January 2025
Neuromodulation Laboratory, Department of Rehabilitation Sciences, KU Leuven, Leuven, Belgium.
Intranasal administration of oxytocin is emerging as a potential pharmacological option for mitigating social difficulties and regulating stress in autism spectrum disorder. However, initial single-dose and multiple-dose trials showed mixed results, with some demonstrating improvements in social and repetitive behavior and others showing no benefit over placebo. This perspective aims to elucidate factors contributing to this variability and to highlight pitfalls and opportunities in the field.
