BACKGROUND Cachexia affects the majority of patients with advanced cancer and is associated with a reduction in treatment tolerance, response to therapy, and duration of survival. One impediment towards the effective treatment of cachexia is a validated classification system. METHODS 41 patients with resectable upper gastrointestinal (GI) or pancreatic(More)
In Scotland, the 2009 outbreak of Bacillus anthracis infection among persons who inject drugs resulted in a 28% death rate. To compare nonsurvivors and survivors, we obtained data on 11 nonsurvivors and 16 survivors. Time from B. anthracis exposure to symptoms or hospitalization and skin and limb findings at presentation did not differ between nonsurvivors(More)
BACKGROUND Muscle depletion is a poor prognostic indicator in colorectal cancer (CRC) patients, but there were no data assessing comparative temporal body composition changes following elective CRC surgery. We examined patient skeletal muscle index trajectories over time after surgery and determined factors that may contribute to those alterations. (More)
Muscle wasting in old age or cancer may result from failed myofiber regeneration and/or accelerated atrophy. This study aimed to determine from transcriptomic analysis of human muscle the integrity of the cellular stress response system in relation to satellite cell differentiation or apoptosis in patients with cancer (weight-stable (CWS) or weight-losing(More)
BACKGROUND Preoperative weight loss and abnormal serum-albumin have traditionally been associated with reduced survival. More recently, a correlation between postoperative complications and reduced long-term survival has been reported and the significance of the relative proportion of skeletal muscle, visceral and subcutaneous adipose tissue has been(More)
BACKGROUND Endovascular technology now permits total endovascular thoracoabdominal aortic aneurysm (TAAA) repair with high volume centres reporting encouraging results. The long-term durability of such stent grafts is unknown, leading to concerns regarding their use in younger patients. This study reports contemporary outcomes of open repair in young(More)
The authors sought to evaluate the visual search patterns of mammographers to better understand the process by which a diagnosis is reached when mammographic images are viewed. An unobtrusive gaze tracking system was applied to track gaze direction and pupil size. Data were collected at 60 Hz and analyzed to evaluate how visual search patterns (location and(More)
Retrograde transport of fluorescent latex microspheres was combined with immunocytochemistry for glutamate to determine the organization of the projections from glutamate-containing neurones in the rostral hypothalamus to the different subdivisions of the periaqueductal grey (PAG). Double-labelled neurones, i.e. neurones immunoreactive for glutamate and(More)
