Multimodal Prehabilitation in Gastric Cancer Patients

This single-arm phase II trial investigates whether a multimodal prehabilitation program can attenuate the postoperative inflammatory response in patients undergoing curative gastric cancer surgery. Major abdominal surgery induces a pronounced systemic inflammatory reaction that contributes to postoperative complications, delayed recovery, impaired functional status, and reduced tolerance to adjuvant therapy. Elevated postoperative C-reactive protein (CRP) trajectories have been associated with infectious complications, whereas a timely decline in CRP may reflect a more adequate immune response. Interventions that improve nutritional status, physical fitness, and psychological resilience before surgery may modulate these inflammatory processes. The PING-P intervention combines three components starting two weeks before surgery and continuing for three weeks postoperatively: (1) structured exercise including resistance, aerobic and respiratory training supported by pulsed electromagnetic field (PEMF) therapy to both thighs twice weekly; (2) individualized nutritional therapy with counseling and provision of omega-3-enriched high-protein oral nutritional supplements twice daily to achieve ≥1.2 g/kg/day protein intake; and (3) psychological support using coaching and digital relaxation tools. The program is delivered in hospital and at home using a mobile application with regular monitoring and feedback. The primary objective is to evaluate whether this multimodal approach reduces the proportion of patients with a poor postoperative immune response, defined as either a CRP peak ≥166 mg/L or a decrease from peak CRP to two days later of \<35%. CRP will be measured from postoperative day (POD) 1 to POD7 or until discharge. Secondary objectives include assessment of feasibility (recruitment, retention, and adherence to ONS intake, PEMF sessions, and exercises), postoperative infectious and overall complications, intervention-related adverse events, functional recovery, nutritional status, body composition, and quality of life. Adults with histologically proven gastric or esophagogastric junction cancer (Siewert II-III) scheduled for minimally-invasive curative gastrectomy at National University Hospital and Ng Teng Fong General Hospital, Singapore, will be enrolled. Exclusion criteria include distant metastases, emergency surgery, need for preoperative tube or parenteral feeding, inability to follow the program, or contraindications to oral nutrition. A total of 25 participants will be recruited. The study will provide first data on whether targeted multimodal prehabilitation can favorably modify perioperative inflammation and inform the design of a future randomized trial.

Circulatory Exercise After Total Knee Replacement

Total knee replacement is commonly associated with early postoperative inflammation, edema, pain, and reduced mobility. This randomized controlled trial will evaluate whether adding a simple circulatory exercise program to standard postoperative rehabilitation reduces early limb edema and inflammatory response after unilateral primary total knee replacement. Participants will be randomized to standard rehabilitation alone or standard rehabilitation plus seated and supine knee-extension exercises with alternating ankle dorsiflexion. The primary endpoint is change in limb edema measured by standardized limb circumference at postoperative day 14.

Preoperative Shoulder Exercises and Postoperative Inflammation, Pain, and Function After Modified Radical Mastectomy

This study evaluates whether preoperative shoulder range-of-motion exercises influence postoperative inflammatory response, pain, shoulder function, and quality of life in patients with locally advanced breast cancer undergoing modified radical mastectomy.

Efficacy of NSAID vs. Steroid-NSAID Combo Post-Selective Laser Trabeculoplasty: Phase 4, Single-Center RCT

This clinical trial, led by Dr. Enitan A. Sogbesan at the Hamilton Regional Eye Clinic, St. Joseph's Healthcare Hamilton, aims to compare the efficacy and safety of non-steroidal anti-inflammatory drug (NSAID) ketorolac alone versus a combination of ketorolac and the corticosteroid fluorometholone, and a control group receiving no postoperative treatment. The trial will evaluate these treatment strategies following Selective Laser Trabeculoplasty (SLT) in patients with open-angle glaucoma. The primary objective is to determine the most effective postoperative management strategy to reduce inflammation, improve patient comfort, and control intraocular pressure (IOP). Participants will be randomly assigned to one of the three groups, with follow-up visits scheduled at 1 hour, 1 week, 1 month, 3 months, 6 months, and 1 year post-SLT. The study's findings aim to guide clinicians in optimizing postoperative care for better patient outcomes.
