Clinical and intracranial electrophysiological signatures of post-operative and post-ictal delirium.

Objectives: (1) Gain insight into the mechanisms of postoperative delirium (POD). (2) Determine mechanistic overlap with post-ictal delirium (PID). Epilepsy patients undergoing intracranial electrophysiological monitoring can experience both POD and PID, and thus are suitable subjects for these investigations.

Janus LAAM-loaded electrospun fibrous buccal films for treating opioid use disorder.

The opioid crisis has claimed approximately one million lives in the United States since 1999, underscoring a significant public health concern. This surge in opioid use disorder (OUD) fatalities necessitates improved therapeutic options. Current OUD therapies often require daily clinical visits, leading to poor patient compliance and high costs to the health systems.

Divergent Effects of Ketamine and the Serotoninergic Psychedelic 2,5-Dimethoxy-4-Iodoamphetamine on Hippocampal Plasticity and Metaplasticity.

Introduction: Serotonergic psychedelics and ketamine produce rapid and long-lasting symptomatic relief in multiple psychiatric disorders. Evidence suggests that despite having distinct molecular targets, both drugs may exert therapeutic benefit via their pro-neuroplastic effects. Following treatment with ketamine or serotonergic psychedelics, patients are reported to be more open to behavioral change, which is leveraged for psychotherapy-assisted reframing of narratives of the self.

Effects of the kappa-opioid receptor antagonist nor-binaltorphimine on methamphetamine-vs-food choice in male rhesus monkeys.

Background: Kappa-opioid receptors (KOR) are hypothesized to be involved in mediating ongoing methamphetamine self-administration. Previous rat studies have demonstrated that treatment with the KOR antagonist nor-binaltorphimine (nor-BNI) decreases methamphetamine self-administration. However, KOR antagonist effects on methamphetamine self-administration in nonhuman primates are unknown.

Revalidation of Proactive Gastrostomy Tube Placement Guidelines for Head and Neck Cancer Patients Receiving Helical Intensity-Modulated Radiotherapy.

The Royal Brisbane and Women's Hospital (RBWH) Swallowing and Nutrition Management Guidelines for Patients with Head and Neck Cancer were developed to enable evidence-based decision-making by the Head and Neck Multidisciplinary Team (H&N MDT) regarding enteral nutrition support options. The purpose of this study was to revalidate these guidelines in a cohort of patients receiving helical intensity-modulated radiotherapy (H-IMRT) compared to a historical cohort who received primarily 3D-conformal radiotherapy. Eligible patients attending the RBWH H&N MDT between 2013 and 2014 (n = 315) were assessed by the guidelines, with high-risk patients being recommended proactive gastrostomy tube placement.
