Hepatocellular cancer: The impact of obesity, type 2 diabetes and a multidisciplinary team

TL;DR: HCC related mortality is increasing, with typical patients being elderly with metabolic risk factors, but older patients with co-morbidities can do well, managed, within a specialist multidisciplinary team if their cancer is detected pre-symptomatically.
Journal ArticleDOI

Submaximal cardiopulmonary exercise testing predicts complications and hospital length of stay in patients undergoing major elective surgery.

TL;DR: An objective measure of cardiorespiratory reserve was an independent predictor of a major surgical group with increased postoperative complications and hospital LOS, and AT measurement significantly improved outcome prediction compared with an algorithm-based activity assessment.
Journal ArticleDOI

Chemotherapy-associated liver injury in patients with colorectal liver metastases: a systematic review and meta-analysis.

TL;DR: Chemotherapy before resection of colorectal liver metastases is associated with an increased risk of regimen-specific liver injury, which may have implications for the functional reserve of the liver for patients undergoing major hepatectomy for coloreCTal Liver metastases.
Journal ArticleDOI

Cardiorespiratory Fitness Predicts Mortality and Hospital Length of Stay After Major Elective Surgery in Older People

TL;DR: Cardiorespiratory fitness is an independent predictor of mortality and length of hospital stay and provides significantly more accurate prognostic information than age alone, and Clinicians should consider both the prognostic value of cardiore Spiratory testing and techniques to preserve cardioryspiratory function before elective surgery in older people.
Journal ArticleDOI

Routine intraoperative ureteric stenting for kidney transplant recipients
