Postoperative Outcomes

The goal of this clinical trial is to learn whether high-dose multimodal prehabilitation, delivered either in person or remotely with coaching and web application support, is feasible and acceptable for women preparing for ovarian cancer surgery. It will also examine which delivery model patients prefer and the factors influencing patient preferences. The main questions ADAPT-OC aims to answer are: 1. Can participants achieve the prescribed aerobic exercise target of at least 10 MET-hours per week before surgery? 2. Do patients prefer in-person prehabilitation, remote prehabilitation, or education-only care, and what factors influence that preference? The researchers will compare in-person prehabilitation, remote prehabilitation, and education-only care to see which delivery approach is most feasible, acceptable, and practical for patients with suspected ovarian cancer. Participants will: * Choose their preferred study group, or be randomly assigned if they have no preference * Complete physical assessments, questionnaires, and interviews at baseline, 1-3 days before surgery, and 4 weeks after surgery * If assigned to a prehabilitation group, complete aerobic exercise, protein supplementation, and daily breathing exercises before surgery * Attend weekly coaching sessions with a trained prehabilitation coach * Use the KingstonPrehab web application to track exercise, nutrition, breathing practice, and progress toward activity goals

To evaluate the diagnostic efficiency of the neural network in predicting complications of Small Incision Lenticule Extraction in a multi-center cross-sectional study.

This prospective observational study will assess the impact of standardized perioperative nutritional care on postoperative outcomes in patients undergoing elective total hip (THA) or knee arthroplasty (TKA) at the First Department of Orthopaedic Surgery, St. Anne's University Hospital in Brno. The protocol includes preoperative patient education, nutritional risk screening, and carbohydrate loading up to two hours before anesthesia, followed by early postoperative refeeding. Data collection will include demographic and surgical variables, nutritional status, carbohydrate intake, and the occurrence of intra- and postoperative complications, including infection and delayed wound healing. As perioperative nutritional care is part of routine clinical practice, the study requires no additional interventions or resources. Results will provide evidence on the effectiveness of structured nutritional support in enhancing recovery and reducing complications after joint replacement surgery.
