AI Article Synopsis
- This study investigates how preoperative stress affects brain inflammation and cognitive issues after surgery, particularly in older adults.
- In aged rats, stress before surgery led to heightened brain inflammation and worse cognitive abilities after the operation, with these issues lasting for up to 28 days.
- The results imply that reducing preoperative stress could improve recovery and cognitive health for elderly patients post-surgery.
Article Abstract
Objective: This study examines the impact of preoperative stress on postoperative neuroinflammation and associated cognitive dysfunction, with a focus on aged individuals. The goal is to determine whether managing preoperative stress can enhance postoperative outcomes and lower the risk of cognitive impairment.
Results: In aged rats, preoperative restraint stress significantly worsened neuroinflammation and cognitive deficits following abdominal surgery. Elevated levels of pro-inflammatory cytokines were observed in the hippocampus and medial prefrontal cortex two days post-surgery, and these effects persisted for twenty-eight days. In contrast, adult rats did not show significant changes in neuroinflammation or cognitive function due to preoperative restraint stress. An ex vivo analysis indicated that hippocampal microglia from aged rats exhibited an intensified proinflammatory response to lipopolysaccharide stimulation, further heightened by preoperative restraint stress. These findings suggest that managing preoperative stress could mitigate these adverse effects, leading to better postoperative recovery and cognitive health in elderly patients.

The Autologous Fascial Pubovaginal Sling for Recurrent Stress Incontinence: A Retrospective Study.
Low Urin Tract Symptoms
January 2025
Department of Urology, Institute of Urology (Laboratory of Reconstructive Urology), West China Hospital, Sichuan University, Chengdu, Sichuan, People's Republic of China.
Aim: This study aimed to analyze the clinical efficacy and safety of autologous fascial pubovaginal sling (AFPVS) surgery in treating recurrent stress urinary incontinence (SUI) following the failure of mid-urethral sling procedures.
Methods: A retrospective analysis was conducted on the clinical data of SUI patients who underwent AFPVS at our hospital between 2008 June and 2024 June following the failure of mid-urethral sling procedures. The analysis included basic information, surgical parameters, and postoperative complications.
Purpose: To investigate long-term corneal biomechanical changes in thin corneas after small incision lenticule extraction (SMILE).
Methods: Patients with indications for SMILE were enrolled in this study between November 2017 and March 2018. Patients were matched for age, spherical diopter, cylinder, spherical equivalent (SE), and lenticule thickness (LT), and then categorized into the thin cornea group (preoperative thinnest central corneal thickness [CCT] of 500 µm or less, 32 eyes) or normal cornea group (CCT of greater than 500 µm, 32 eyes).
Identifying Components of an Enhanced Recovery Pathway for Primary Cleft Palate Repair: A Scoping Review.
Cleft Palate Craniofac J
January 2025
Department of Plastic Surgery, Children's Health Ireland at Crumlin, Dublin, Ireland.
Objective: This study aims to map the existing sources of evidence on perioperative care and recovery strategies for primary cleft palate repair, to identify elements that should be included in an enhanced recovery pathway (ERP), and to identify gaps in current knowledge.
Design: Scoping review.
Setting: ERPs are evidence-based, patient-centered, multimodal, perioperative care pathways designed to reduce surgical stress and improve postoperative outcomes and are increasingly being reported in the cleft lip and palate literature.
Poor Colonoscopy Bowel Prep in Cognitively Impaired 85‐Year‐Old with Low Education: Another Case Example.
Alzheimers Dement
December 2024
University of Florida, Gainesville, FL, USA
Introduction: Colonoscopies are routine procedures performed primarily on adults over the age of 50; however, there is little known about the influence of social determinants of health on successful completion of colonoscopies. Inadequate at‐home bowel preparation can result in increased procedure duration, decreased cancer detection, and may necessitate a repeated colonoscopy, putting undue stress on the patient. Research suggests neurocognitive disorder is a risk factor for poor bowel preparation in older adults; however, lower education may confound neurocognitive findings, independently contributing to risk of incomplete colonoscopies.

J Orthop Surg Res
January 2025
Key Laboratory for Biomechanics and Mechanobiology of Ministry of Education, Beijing Advanced Innovation Center for Biomedical Engineering, School of Biological Science and Medical Engineering, Beihang University, Beijing, 100083, China.
Background: Meniscus tears can change the biomechanical environment of the knee joint and might accelerate the development of osteoarthritis. The aim of this study was to investigate the dynamic biomechanical effects of different medial meniscus tear positions and tear gaps on the knee during walking.
Methods: Seven finite element models of the knee joint were constructed, including the intact medial meniscus (IMM), radial stable tears in the anterior, middle, and posterior one-third regions of the medial meniscus (RSTA, RSTM, RSTP), and the corresponding unstable tears (RUTA, RUTM, RUTP).
