Active clinical trials for "Nutrition Disorders"

The incidence of malnutrition in patients with severe neurological diseases is approximately 37%, among which hypoproteinemia is a common manifestation. It has been confirmed that serum albumin level is closely related to severity and mortality for patients. Protein is the basic component of tissue cells in the body, which plays an important role in the growth and development of senescent cells and the repair of damaged tissues. At present, the results of some randomized controlled studies show that it is difficult to achieve enough protein supplementation by commercial standard enteral nutrition agents alone, and additional protein supplementation is required. Commercial standard enteral nutrition preparations, whose whole protein components are casein and soy protein, do not achieve optimal uptake and utilization compared to whey proteins, which are more readily absorbed and utilized by the human gut. Whey protein and its hydrolyzed products have better nutritional quality than casein, which can provide high-quality nitrogen source for enteral nutrition and play an important role in correcting negative nitrogen balance, promoting wound healing and improving body immunity. Whether whey protein supplementation based on standard enteral nutrition preparation can improve serum albumin level and reduce the incidence of hypoproteinemia in patients with severe acute neurological disease has not been proved. In conclusion, we propose the hypothesis that compared with the standard enteral nutrition preparation regimen, the enteral nutrition regimen supplemented with whey protein in patients with severe neurological disease is more beneficial to improve the nutritional indicators of patients and reduce the occurrence of hypoproteinemia. It is expected that this randomized controlled trial will provide a new clinical basis for optimizing the enteral nutrition support program for patients with severe neurological diseases.

The overall goal of this inquiry is to determine whether PALS is more effective than comparable online resources at educating patients in the outpatient clinic setting about nutrition. Participants will be randomly assigned to view either a PALS article or WebMD article on the same nutrition topic. Participants will then fill out a post-survey to assess knowledge uptake and attitudes regarding healthy eating.

The aim is to define in detail metabolic pathways at rest and during aerobic exercise in normal and healthy men and women under normobaric normoxic and moderate hypoxic conditions, using metabolomics technologies based on minimally invasive sampling relying on gas chromatography and mass spectrometry.

This study aims to measure skeletal muscle metabolism in vivo during exercise using the non-invasive Magnetic Resonance Spectroscopy (MRS) technique. Specifically, phosphocreatine (PCr) kinetic and Acetylcarnitine levels will be determined at resting, during exercise and during the recovery post exercise. The target population is adult healthy men, with a wide range of maximal physical capacity.

The study compares nutritional status of two groups elderly patient aged 65 and more. One group of the patients received nutritional support (Nutridrink Multi Fibre) for 14 days. Nutritional status of the patients were compared 2 months after the start of the intervention.

Despite numerous studies of meal components in humans, little is still known about how different meals influence on metabolism. The purpose of this study is to a gain knowledge of how a balanced test meal with either lean seafood (example:cod) or meat as the main protein source will: affect the postprandial metabolism acutely (test-meal at beginning of the study) affect the postprandial metabolism after 4 weeks controlled intervention (test meal at end of intervention period) affect gut microbiota composition

Gut microbiota ecology is altered in obesity and could link obesity and its complications. Bariatric surgery enables a major and sustained weight loss therefore improving obesity related disease. the investigators primary aim is to evaluate gut microbiota adaptation to weight loss and the specific role of energetic restriction. Furthermore we aim to compare gut flora of obese patients post bariatric surgery to that of lean healthy volunteers. Thus, the investigators plan to compare gut microbiota from 140 obese individuals before and after either restrictive (gastric banding) procedures or gastric bypass procedures to that of 40 lean healthy volunteers at baseline.

The incidence of oesophagogastric cancer has increased by 400% since the 1970s in Ireland and the United Kingdom. In addition, refinement of perioperative management and the now widespread use of multimodal protocols for patients with locally advanced disease have significantly improved outcomes for patients with oesophagogastric cancer treatable with curative intent. Despite significant advances in chemoradiotherapy, surgical resection remains the primary curative option. Unintentional weight loss and nutritional complications represent serious concerns for patients after radical resection, even among those who remain free from recurrent disease in the long-term. A study from the Swedish Esophageal and Cardia Cancer Registry reported a mean three year weight loss of 10.8% among disease-free patients, with 33.8% of this cohort demonstrating malnutrition at three years post-oesophagectomy. Mechanisms contributing to weight loss for disease-free patients after upper gastrointestinal surgery are poorly understood, however an association between increasing magnitude of weight loss and the presence of increased satiety is described. Our recent studies at SJH have demonstrated four fold elevated postprandial satiety gut hormone concentrations after oesophagectomy, compared with baseline preoperative values. Postprandial gut hormone levels correlate significantly with postprandial symptoms and altered appetite at 3 months postoperatively, and with body weight loss at 2 years postoperatively. However, the mechanism leading to exaggerated postprandial gut hormone production after upper gastrointestinal surgery is poorly understood, limiting targeted therapeutic options. In this study, we aim to characterise the role of altered nutrient transit and enteroendocrine cell function in the pathophysiology of excessive post-prandial gut hormone responses after upper gastrointestinal surgery. To do this, we will measure the gut hormone response to a standardised 400 kcal meal, as per previous studies, while concurrently assessing gastrointestinal transit time, and enteroendocrine cell morphology and function. In this way, we will determine whether the magnitude of the postprandial gut hormone response correlates with the rate of nutrient transit into the enteroendocrine L-cell rich small intestine, and whether enteroendocrine cell adaptation occurs after oesophagectomy. Furthermore, we have previously observed that gut hormone suppression using octreotide is associated with increased ad libitum among subjects after upper gastrointestinal cancer surgery (Elliott JA et al, Annals of Surgery, 2015). The mechanism of action of octreotide may relate to SSTR-5-mediated negative feedback to the enteroendocrine L-cell, but this medication may additionally reduce enteroendocrine L-cell responses through its inhibitory effect on gastrointestinal motility - reducing the rapidity with which nutrients are delivered to the small intestine - and small intestinal nutrient sensing via inhibition of the Na+-dependent glucose transporter SGLT-18-10. Through conduction of this double-blind, randomised, placebo-controlled crossover study, we aim to establish the mechanism of action of octreotide-mediated increased food intake in patients after gastrointestinal surgery. This may inform the design of future targeted interventions for this patient group.

Relative Energy Deficiency in Sport (RED-S) characterizes a range of negative health and performance outcomes that result from chronically low energy availability. RED-S concerns high performance junior and senior athletes across Canada and has a prevalence rate of 3-60%. Our ability to assess and diagnose RED-S remains poor. Accordingly, we aim to create the best parameters to diagnose and manage RED-S; along with information of the prevalence and severity across Canada and globally. These outcomes are expected to have a significant positive impact on the health and performance of Canadian athletes in preparation for the Olympic Games in 2022 and beyond.

To determine whether the consumption of a beef-rich lunch improves appetite control, satiety, and energy intake regulation while reducing food reward and food cravings compared to the consumption of a soy-rich lunch when matched for macronutrients and fiber content or when match for serving size. The mechanisms of action surrounding the differential responses of beef versus soy proteins were also explored.
