Sarcopenia is independently associated with poor preoperative physical fitness in patients undergoing colorectal cancer surgery.

Background: Accurate preoperative risk assessment for major colorectal cancer (CRC) surgery remains challenging. Body composition (BC) and cardiopulmonary exercise testing (CPET) can be used to evaluate risk. The relationship between BC and CPET in patients undergoing curative CRC surgery is unclear.

First Clinical Results of the Merit WRAPSODY™ Cell-Impermeable Endoprosthesis for Treatment of Access Circuit Stenosis in Haemodialysis Patients.

Purpose: This prospective, observational first in human study evaluated the safety and effectiveness of WRAPSODY Cell-impermeable Endoprosthesis (Merit Medical Systems, Inc.) in the treatment of arteriovenous fistula and arteriovenous graft access circuit stenosis.

Materials And Methods: Investigators conducted a prospective analysis of 46 patients with access circuit stenosis from three centres.

Total psoas area predicts medium-term mortality after lower limb revascularization.

Background: Analytic morphometry is a novel concept in perioperative risk assessment. Low core muscle mass assessed by morphometry is associated with frailty and has been demonstrated to be an independent predictor of postoperative complications and mortality in oncologic, transplant, and aneurysm surgery. We aimed to study associations between core muscle mass and complication rates, length of hospital stay, and survival after surgical lower limb revascularization.
