The Medical Team

Jeremy Powell-Tuck

Jeremy Powell-Tuck is Professor of Clinical Nutrition at Barts and the London, Queen Mary's School of Medicine and Dentistry. He is a consultant gastroenterologist at Barts and the London NHS Trust with a particular interest in artificial feeding and intestinal failure. He links with the Wingate Institute at the Royal London Hospital, which has a long standing research interest in severe chronic intestinal dysmotility.

Research Activity

My research is orientated to the assessment and management of acute and chronic intestinal failure in order to improve nutritional support in hospitalised patients and patients with long term intestinal failure needing treatment at home.

Refeeding syndrome is an important cause of mortality after hospitalisation in developing countries and is increasingly recognised as a major metabolic complication associated with the refeeding of patients in hospital here. Study 1 addresses in detail the endocrine and metabolic responses to refeeding in the unusual context of a compliant faster, not complicated by disease. Study 4 adds to our knowledge of body composition changes during fasting.

We have been working with colleagues on the Intensive Care Unit to enhance nutritional support in critical care. Patients fed early, enterally do best clinically and we have been studying the gastric emptying responses to continuous and bolus feeds in patients on the borderline of enteral feed gastro-intestinal intolerance. This (2) is a pilot study in normals developing a technique which can be subsequently used on the ICU. The studies in critical care have been analysed and will shortly be submitted.

Dr Nigel Meadows MD FRCP FRCPCH

Lead clinician for paediatric gastroenterology. Role in coordinating the activities of the department and collaborating with academic unit. Also is responsible for the running of our network of outreach clinics throughout the south east of England.

I am a member of the council of the British Society of paediatric gastroenterology, Hepatology and Nutrition. In this capacity I chair the Clinical Standards committee.

I am also a member of the Royal College of paediatrics and child nutrition committee, and the British Society of Gastroenterology Clinical standards committee.

I am an active member of the British artificial Nutrition surgery (BANS), and sit on the Paediatric Intestinal Failure group.

I am a member of 2 patient support groups. National association of Crohns and Colitis (NACC) and Pseudo obstruction Research Trust (PORT), in which capacity I act as a medical advisor.

My activities in the Royal College include being a Senior examiner for the MRCPCH exam. In terms of undergraduate exams i am an external examiner for the University of London at St Georges Hospital.

My research interests include the provision of artificial nutrition support any dysphagia in children. I lecture nationally on feeding difficulties in children and obesity.

Dr Nikhil Thapar BSc (Soton). BM(Soton). MRCP (UK). MRCPCH PhD (UoL)

Dr Nikhil Thapar undertook his medical training at the University of Southampton. Within this he also completed an Interealated BSc in Biomedical Sciences. After graduating from Southampton in 1993 he completed his pre-registration house officer posts in Southampton General Hospital and Queen Alexandra Hospital, Portsmouth.

Having attained the MRCPCH Dr Thapar went on to complete his core Specialist Registrar  training in Portsmouth. He developed an interest in Gastroenterology and left the region to train in the sub-speciality by virtue of the National Treasure sub-speciality rotation based in the North Thames London region. These included posts at the Royal Hospital and Great Ormond Street Hospitals, as well as hepatology training at King’s College Childrens Liver Unit. During this time he became especially interested in the management of gastro-intestinal Neuro-muscular disorders, he went on to complete doctoral (PhD) training at the National Institute for Medical Research London, where he researched the development of the gut nervous system and use of stem cell therapies.

Dr Thapar returned to the Institute of Child Health and Great Ormond Street Hospital in 2004 where he is pursuing his academic career and research interest as a clinician scientist. He is also an honorary Consultant Paediatric Gastroenterologist at Great Ormond Street Hospital.

Professor Qasim Aziz PhD, FRCP

Professor of Neurogastroenterology

Director, Wingate Institute of Neurogastroenterology

Biography

He moved to Barts and The London in December 2006. Professor Aziz has pioneered the use of neurophysiological techniques to study human brain gut interactions in health and disease. His PhD work led to the identification of the cortical representation of swallowing muscles.

Research Activity

His major research interest is to study the mechanisms of visceral pain in health and disease. His work has contributed to the current understanding of the brain neural networks involved in processing human gut sensation using functional brain imaging techniques. He has a particular interest in how the perception and the brain processing of visceral pain are modulated by psychological factors. In addition he has studied the role of inflammation / injury in sensitising visceral nerves in health and in functional gastrointestinal disorders. His current research interests include the study of psycho-physiological factors that predict the inter-individual variability in pain perception.

Mr Charles H Knowles MBBChir, PhD, FRCS, FRCS (Gen Surg)

Biography

Charles Knowles undertook his preclinical training at Cambridge University and then moved to the London Hospital Medical College , qualifying in 1992.
