Preventing Spinal-induced Hypotension During Elective Cesarean Sections.

Purpose: The purpose of this quality improvement project was to implement an evidence-based intraoperative protocol to reduce the incidence of spinal-induced hypotension during elective cesarean sections.

Design: A quality improvement project.

Methods: After receiving education, anesthesia providers implemented the intraoperative protocol for 6 weeks on elective cesarean sections.

A Reinforcement Learning approach to study climbing plant behaviour.

A plant's structure is the result of constant adaptation and evolution to the surrounding environment. From this perspective, our goal is to investigate the mass and radius distribution of a particular plant organ, namely the searcher shoot, by providing a Reinforcement Learning (RL) environment, that we call Searcher-Shoot, which considers the mechanics due to the mass of the shoot and leaves. We uphold the hypothesis that plants maximize their length, avoiding a maximal stress threshold.

The Application of Radiofrequency Ablation in Acute and Chronic Pain Management.

Radiofrequency ablation (RFA), also known as rhizotomy, is one of the frequently used modalities in interventional pain management. This nonsurgical procedure delivers radiofrequency waves to the targeted nerves to interrupt transmission of nociceptive signals from the peripheral tissues to the central nervous system, thereby reducing pain perception. Recent studies have demonstrated the efficacy of RFA treatment as an effective interventional pain management technique to treat a variety of acute and chronic pain conditions including facial pain, headaches, postmastectomy, musculoskeletal, and major joint pain (knee, hip, shoulder, sacroiliac), and cancer pain.

Characteristics Associated with Relationship-Centred and Task-Focused Mealtime Practices in Older Adult Care Settings.

To assess care home and staff characteristics associated with task-focused (TF) and relationship-centred care (RCC) mealtime practices prior to the COVID-19 pandemic. Staff working in Canadian and American care homes were invited to complete a 23-item online survey assessing their perceptions of mealtime care, with one item assessing 26 potential care practices from the Mealtime Relational Care Checklist (relationship-centred = 15; task-focused = 11) reported to occur in the home prior to the pandemic. Multivariate linear regression evaluated staff and care home characteristics associated with mealtime practices.
