OBJECTIVE To evaluate the impact of the route of administration of artificial nutrition and the composition of the diet on outcome. DESIGN Prospective, randomized, clinical trial. SETTING Department of surgery, university hospital. PATIENTS One hundred sixty-six consecutive patients undergoing curative surgery for gastric or pancreatic cancer. (More)
HYPOTHESIS Perioperative administration of a supplemented enteral formula may reduce the rate of postoperative infections. DESIGN Prospective, randomized, double-blind clinical trial. SETTING Department of surgery at a university hospital. PATIENTS Two hundred six patients with neoplasm of colorectum, stomach, or pancreas. INTERVENTION Patients were(More)
OBJECTIVE To study the effect of the route of delivery and formulation of postoperative nutritional support on host defense, protein metabolism, infectious complications, and outcome. DESIGN Prospective, randomized, clinical trial. SETTING Department of Surgery at a university hospital. PATIENTS Two hundred sixty candidates for pancreaticoduodenectomy(More)
BACKGROUND Although current opinion favours the use of enteral over parenteral nutrition, the clinical benefits of early postoperative nutrition in patients undergoing elective surgery have never been clearly shown. We aimed to test the hypothesis that postoperative enteral nutrition is better (fewer postoperative complications) than parenteral nutrition(More)
Patients undergoing pancreaticoduodenectomy (PD) often require postoperative artificial nutrition. This trial was undertaken to evaluate whether the route of administration and the composition of the postoperative nutritional support could affect the immunometabolic response and outcome. A prospective, randomized trial was carried out in 212 subjects who(More)
In 40 out of 99 patients (40.4%) with solid tumours of different tissue, but the same stage (IV), elevated serum levels of interleukin-10 were observed. The mean levels of the cytokine in patients with malignant melanoma (24.3 ng/ml), pancreatic (6.8 ng/ml) or gastric (6.3 ng/ml) adenocarcinoma were significantly higher than in healthy subjects (3.4 ng/ml)(More)
OBJECTIVE Alprazolam (ALP), a benzodiazepine-activating GABAergic receptor, possesses clear centrally mediated inhibitory effects on ACTH and cortisol secretion that could reflect an inhibitory influence on CRH- and/or AVP-secreting neurones. An inhibitory effect of ALP on catecholamine release has also been shown while its effect on GH secretion is(More)
Galanin enhances both baseline and growth hormone-releasing hormone (GHRH)-induced GH secretion both in animals and in man. Although galanin has a clear influence on the secretion of other anterior pituitary hormones in animals, in man it increases prolactin (PRL) slightly but does not affect spontaneous thyrotropin (TSH), luteinizing hormone (LH),(More)
The gut can be a source of sepsis after thermal injury. In the present study the relationship between the extent of burn injury and magnitude of bacterial translocation was investigated. Mice underwent 0%, 10%, 20%, 30%, or 50% total body surface area full-thickness burn and simultaneous gavage with 1 x 10(10) 14C-labeled Escherichia coli. mesenteric lymph(More)
Hexarelin (HEX) is a synthetic GHRP which acts on specific receptors at both the pituitary and the hypothalamic level to stimulate GH release both in animals and in humans. Like other GHRPs, HEX possesses also acute ACTH and cortisol-releasing activity similar to that of hCRH. The mechanisms underlying the stimulatory effect of GHRPs on(More)
