Long-term Follow-up of Dexmedetomidine-esketamine and tDCS for Neurocognitive Complications After Surgery
Neurocognitive complications, mainly delirium and neurocognitive disorders, are common cerebral complications in older patients after surgery and associated with worse long-term outcomes. An ongoing 2×2 factorial trial conducted by the investigators plan to test the effects of perioperative dexmedetomidine-esketamine combination and transcranial direct current stimulation (tDCS) on postoperative neurocognitive complications in older patients. This long-term follow-up of the ongoing trial aims to investigate the effects of perioperative dexmedetomidine-esketamine combination and tDCS on long-term outcomes in older patients after noncardiac surgery.

Dexmedetomidine-esketamine and tDCS for Prevention of Neurocognitive Complications After Surgery
Neurocognitive complications, mainly delirium and neurocognitive disorders, are common cerebral complications in older patients after surgery and associated with worse outcomes. In previous studies, perioperative use of dexmedetomidine-esketamine combination improved analgesia and sleep quality after surgery. Perioperative use of transcranial direct current stimulation (tDCS) also improved sleep quality and reduced delirium occurrence early after surgery. This 2×2 factorial trial is designed to investigate the effects of perioperative dexmedetomidine-esketamine combination and tDCS on delirium occurrence and early postoperative neurocognitive recovery in older patients.

Detection of Cerebral Ischemia With Artificial Intelligence.
In patients undergoing planned surgery for carotid tromendarterendectomy, a non-invasive device that registers heart rate variability is attached. Furthermore a non-invasive device that monitors cerebral oxygenation- near infrared spectroscopy as well as electroencephalography is also attached. At times when surgeons clamps the carotid artery, there will be a moment with controlled cerebral ischemia. This will be registered by the devices. The information obtained will be used to teach artificial intelligence what patterns are related to cerebral ischemia. The same procedure will be performed in patients undergoing ocklusive cerebral trombectomy, so the artificial intelligence will learn to recognize cerebral reperfusion.Blood samples will be drawn before and after cerebral ischemia may occur and will be analyzed for neurobiomarkers and cardiac biomarkers. To teach the algorithm patterns from anaesthesia and surgery in patients without pre existing neuronal injury, the same method will be applied to patients undergoing mixed abdominal surgery. This group will provide a better knowledge of neuro biomarker patterns during anesthesia and surgery.

COgnitive and Physical Exercise to Improve Outcomes After Surgery (COPE-iOS) Study
The COgnitive and Physical Exercise to improve Outcomes after Surgery (COPE-iOS) study is testing the hypothesis that a pragmatic program combining computerized cognitive training and physical training throughout the perioperative period will improve long-term cognitive and disability outcomes in older surgical patients at high risk for decline. To accomplish these goals, the Investigators are randomizing 250 patients ≥60 years old undergoing elective major non-cardiac surgery with expected hospitalization ≥3 days to a pragmatic comprehensive training program (computerized cognitive training and supervised progressive physical exercise) or to active control (control computer game, stretching exercises) for 2-4 weeks prior to surgery and for 3 months after discharge. At baseline and after discharge, the Investigators will assess global cognition, activities of daily living, depression, endothelial and blood brain barrier function (blood biomarkers), and neuroimaging (anatomical and functional MRI). In this early stage trial, the Investigators will determine if certain subgroups benefit most, program aspects with greatest effect on outcomes, mechanistic associations with outcomes, and additional exploratory analyses.

Surgery vs. Watch-and-Wait Strategy in Partial & Complete Responders for Hepatocellular Carcinoma
The "Surgery versus Maintenance after Conversion-therapy-achieved Complete/Partial Response in Hepatocellular Carcinoma (SWITCH)" study is a multicenter, open-label, prospective non-randomized cohort study with the protocol number SWITCH-01 (Version 0.1, dated October 5, 2025). Sponsored by West China Hospital of Sichuan University and led by Principal Investigator Wu Hong, the study involves 10 participating centers and has completed NCT registration. Its core objective is to evaluate and compare the efficacy and safety of two management strategies-surgical resection and maintenance therapy-in patients with hepatocellular carcinoma (HCC) who have achieved complete response (CR) or partial response (PR) after conversion therapy and are deemed eligible for curative liver resection (R0) by a multidisciplinary team (MDT). The study is designed to address the clinical dilemma of optimal management for initially unresectable HCC patients who attain favorable responses to conversion therapy, providing high-level evidence for clinical decision-making.

Ultrasound Evaluation for Improving Patient Selection in vNOTES
Vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) is an emerging field in minimally invasive surgery. An international consensus-based statement was recently published to help guide the basis for adopting vNOTES into clinical practice, including regarding patient selection. It was agreed that women with potential adhesions are not appropriate candidates for vNOTES approach including women with suspected adhesions due to history of severe pelvic inflammatory disease (PID) or endometriosis. However, as some pelvic infections might be asymptomatic, pre-operation imaging might be beneficial to complete improved selection of patients. Moreover, women with previous severe PID or endometriosis might still have favorable pelvic characteristics to perform the vNOTES approach. Therefore, we aim to compare pre-operation ultrasound evaluation to operative characteristics and outcomes in women undergoing VNOTES approach surgery. Douglas space characteristics, as assessed by ultrasound evaluation of sliding sign, of the patients undergoing vNOTES approach surgery will be compared to patients that were ruled from vNOTES approach in order to evaluate the association of the presence or absence of sliding sign on pre-operation ultrasound to the clinical findings.

Evaluation of a Prehabilitation Program in Patients Requiring Scoliosis Surgery.
Scoliosis is a curvature of the spine that, in the most severe cases, may require surgical treatment. This surgery is invasive and complex, causing anxiety for children, adolescents, and their parents. In-hospital medical and surgical care is well standardized, but there are significant disparities among patients (and their families) in the psychological and physical management of this experience. The hypothesis of the study is that a specific physical and psychological prehabilitation program (a personalized preparation known as "pre-surgical prehabilitation") could improve patient care, particularly in managing anxiety and pre- and postoperative pain throughout the care pathway.

Standardized Educational Videos of Laparoscopic Gynecological Surgeries
Owing to coronavirus disease-related social distancing requirements, online education has gained prominence. Surgical trainers consider online videos as a useful teaching aid that maximizes trainees' learning and skill development given the backdrop of time constraints and productivity demands, however, online videos usually do not undergo a peer-review process. Based on these premises the LAP-VEGaS guidelines (LAParoscopic surgery Video Educational GuidelineS), a recommended checklist for production of educational surgical videos, were developed. This study aime to evaluate the impact of educational videos of laparoscopic gynecological surgeries, that were standardized with the LAP-VEGaS, for the improvement of surgical confidence and performance of surgical trainees.

Evaluating a Dropless Postoperative Regimen After Cataract Surgery in a Vulnerable, County-hospital Population
The current postoperative cataract surgery eye drop regimen used at Zuckerberg San Francisco General Hospital (ZSFG) is a significant burden for its patient population, contributing to high rates of non-adherence and the development of postoperative complications. The investigators propose to replace this complex regimen with a single administration of intraocular antibiotic and subconjunctival steroid at the time of surgery. This pilot study will obtain the preliminary data required to eventually fully evaluate this innovation in postoperative care in a safety-net population with respect to postoperative outcomes, patient compliance, and patient and caregiver satisfaction.
