Filter by:Primary Objective Characterizing precise functional capacity in surgical patients is critical for risk stratification and identification of patients at high risk for perioperative complications. The primary objective for the study is to evaluate the feasibility of effective subject recruitment of an FDA-approved simplified cardiopulmonary exercise testing apparatus in adults >60 years old prior to moderate to high-risk surgery. In addition, by development of a validation cohort of older adults, defined as >60 years old, self-reporting >4 METS and with a score of <2 on the revised cardiac risk index (RCRI)1 we will compare its effectiveness when compared to conventional preoperative evaluation measures (METS determination by standard scoring and Duke Activity Status Index) to SHAPE™ testing.
Rationale: The complication rate after pancreatic resection is high, especially in elderly and physically unfit patients. Aerobic capacity, as indicated by the ventilatory anaerobic threshold (VAT) assessed by a cardiopulmonary exercise test (CPET), can be used to identify high-risk patients. Previous studies have demonstrated that exercise prehabilitation can increase aerobic capacity in patients scheduled for intra-abdominal surgery, subsequently leading to better treatment outcomes. There is limited evidence on the feasibility of a (partly) supervised home-based prehabilitation program in patients scheduled for pancreatic resection. Objective: The primary objective of this study is to assess the feasibility of a four-week supervised home-based prehabilitation program in patients scheduled for elective pancreatic resection. Secondary objectives are to evaluate individual responses to prehabilitation on a number of secondary endpoints (no cause-effect relationship to be established). Study design: This study is a pragmatic multicenter study with a pretest-posttest design. It will take place at the Maastricht University Medical Center+ and University Medical Center Groningen in the Netherlands, and at the 'Città della Salute e della Scienza' in Torino, Italy. Study population: Patients planned for elective resection of a pancreatic tumor will be screened for potential eligibility. High-risk patients, identified by an oxygen uptake (VO2) at VAT ≤13 ml/kg/min and/or VO2peak ≤18 ml/kg/min, will be asked to participate. Intervention: A total of 45 patients will participate in a four-week (partly) supervised home-based personalized exercise training program before surgery (12 sessions in total). An advanced cycle ergometer (Lode Corival, Lode BV, Groningen, the Netherlands) will be delivered at the patient's home. Three weekly sessions of high-intensity interval training on the cycle will be combined with functional task exercise training. A trained physical therapist will visit the patient at least weekly to monitor progress. Main study parameters: The main study parameter is feasibility of the (partly) supervised home-based prehabilitation program. Hereto participation rate and reasons for non-participation will be evaluated. In participating patients, adherence/compliance, dropout rate, reasons for dropout, adverse events, patient motivation, and patient and therapist appreciation will be assessed throughout the program. Secondary endpoints: Secondary endpoints before and after prehabilitation include aerobic capacity, muscle function, body composition, functional mobility, immune system function, perceived fatigue, quality of life, and sarcopenia. Data on patient characteristics, neoadjuvant therapy, surgical procedure, and postoperative outcomes will also be collected for explorative purposes.
The study aims at assessing the influence of β-hydroxy-β-methylbutyrate (HMB) free acid supplementation (90 mg/kg of fat free body mass/day) supplemented for 21 days on protein kinases activity and selected hormones levels, and subsequent improvements in muscle protein synthesis, lean body mass content and aerobic capacity.
