Journal ArticleDOI
Hepatocellular cancer: The impact of obesity, type 2 diabetes and a multidisciplinary team
Jessica K Dyson,B Jaques,Dipankar Chattopadyhay,R. Lochan,Janine Graham,Debasish Das,Tahira Aslam,I Patanwala,Sameer Gaggar,Michael Cole,K Sumpter,Stephen Stewart,John Rose,Mark Hudson,Derek Manas,Helen L. Reeves,Helen L. Reeves +16 more
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.
Chris Snowden,James Prentis,Helen Anderson,D.R.Digby Roberts,Derek Randles,Morag Renton,Derek Manas +6 more
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.
Stuart Robinson,Colin H Wilson,Alastair D. Burt,Alastair D. Burt,Derek Manas,Steven A. White,Steven A. White +6 more
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
Chris Snowden,James Prentis,Byron Jacques,Helen Anderson,Derek Manas,Dave J. Jones,Michael I. Trenell +6 more
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
TL;DR: To examine the benefits and harms of routine ureteric stenting to prevent urological complications in kidney transplant recipients, seven RCTs of low or moderate quality were identified and the incidence of MUCs was significantly reduced.
