Society of American Gastrointestinal and Endoscopic Surgeons guidelines development: Clinical Practice Guideline Update Standard Operating Procedure.

Introduction: The SAGES Guidelines Committee creates evidence-based clinical practice guidelines (CPGs). Updates which incorporate new evidence into the guidelines are necessary to maintain relevance for clinical use. A description of our standard operating procedure for this process is described here, which contributes to SAGES' commitment to producing high-quality clinical recommendations.

SAGES guidelines for the management of comorbidities relevant to metabolic and bariatric surgery.

Background: Patients who are under consideration for or have undergone metabolic and bariatric surgery frequently have comorbid medical conditions that may make their perioperative care more complex. These recommendations address routine intraoperative cholangiography in patients with bypass-type anatomy, the management of reflux disease after sleeve gastrectomy, and the optimal bariatric procedure for patients with comorbid inflammatory bowel disease.

Methods: A systematic review was conducted including studies published from 1990 to 2022 to address these questions.

Turns around periodic spatial boundaries facilitate increasing event segmentation over time.

Event segmentation is a neurocognitive process bridging perception and episodic memory. To our knowledge, almost all segmentation work is framed towards humans, yet evolutionarily conserved mechanisms in event cognition exist across species. Here, we addressed segmentation in a way that is applicable to humans and non-human animals, inspired by research in rats; specifically, the fragmentation of grid-cell spatial representations following the insertion of boundaries into an environment (forming a corridor maze).
