Effect of Cardiovascular Autonomic Neuropathy on AKI and Outcomes in Isolated CABG Surgery

This study aims to investigate the effects of Cardiovascular Autonomic Neuropathy (CAN) on Acute Kidney Injury (AKI) and clinical outcomes in patients undergoing isolated Coronary Artery Bypass Graft (CABG) surgery requiring extracorporeal circulation(ECC). Preoperative data including demographics, comorbidities, kidney function tests, hemodynamic parameters, and baseline regional cerebral oxygen saturation (rSO2) will be recorded. Intraoperative data will include hemodynamics, urine output, blood gases, cardiopulmonary bypass and aortic cross-clamp times, cardioplegia details, number of coronary anastomoses, and rSO2 changes at defined time points. Postoperatively, kidney function, neurological status, mechanical ventilation duration, inotropic drug use, transfusion requirements, complications, ICU and hospital length of stay, and mortality will be evaluated. Acute Kidney Injury will be classified according to KDIGO criteria. The primary objective is to analyze the effect of CAN on AKI. Secondary objectives include assessing the impact of CAN on other clinical outcomes and exploring the relationship between CAN and intraoperative cerebral oxygen changes. This study has been approved by the Acıbadem University and Acıbadem Healthcare Institutions Medical Research Ethics Committee (ATADEK) and will be conducted following ethical principles and good clinical practice.

Diagnostic Efficacy of CNN in Predicting Intraoperative Complications and Postoperative Outcomes in SMILE

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

The Effect of Perioperative Nutritional Care on Recovery After Knee and Hip Replacement Surgery

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.
