Filter by:The investigators hypothesise that there is no increased risk of peri-procedural complications, accompanied by improved patient satisfaction among patients allowed to eat up to the point of coronary angiography/angioplasty compared to patients, kept nil by mouth. Therefore, the investigators aim to change the practice of fasting for all patients before elective catheterization procedures. Consented patients will be randomised in a 1:1 ratio to either fasting (standard hospital fasting policy) or non-fasting (allowed to eat and drink freely up to the point of transfer to the Catheter Laboratory). Primary End Point will composite peri-procedural nausea, vomiting, pre-procedural hypotension, pre-procedural hypoglycemia, intra-procedural emergency endotracheal intubation and aspiration pneumonia. This will be calculated as the number of patients experiencing at least one event. Secondary end-points will include patient satisfaction questionnaire and the individual outcomes assessed in the primary end point.
This is a clinical trial assessing the effects of fasting on the immune system in healthy adults. Immune profiling, gene expression profiling, and flow cytometry on peripheral blood mononuclear cells (PBMCs) will be performed and we hypothesize that a period of fasting will alter the immune system in healthy adults.
The aim of this trial is to investigate the effects of long-term fasting on size, mass, composition and function of metabolic active tissues in several organs that reexpand possibly rejuvenated after 1-4 months. Additionally, the lipid metabolism is investigated in depth.
Preoperative carbohydrate loading has been shown to reduce pre-operative discomfort and postoperative nausea and vomiting. There is no need for prolonged preoperative fasting of the patients, but the traditional approach still continues especially in thoracic surgery patients. For this purpose, we aimed to evaluate the effect of preoperative carbohydrate loading on postoperative morbidity in the patients.
This study aims to describe the dynamic changes in nutritional biomarkers in the blood during the postprandial period, i.e. the time period from the last meal and into the fasting state. In total 36 healthy, young men and women will be recruited in Bergen, Norway, and after receiving a standardized breakfast meal they will consume only water for the next 24 hours.
Diabetes Mellitus individuals are known to have dietary rules, namely regulating the amount, type and time of eating. Ramadan fasting seems to be beneficial for people who want to reduce their weight, but it is not easy for diabetic patients. Because of its distinctive features, Ramadhan induces changes in eating habits, calorie consumption, sleeping patterns, and daily physical activity, which may contribute to changes in hunger-satiety responses and glicemic control. Examining changes in gut hormones during Ramadan fasting may reveal whether this observance could change glucose metabolism in diabetics without triggering the undesirable effect of gluconeogenesis. The proportions of fat, protein, and carbohydrate in meals vary between outside and within Ramadan. Alterations in timing and composition meal during Ramadan lead to reduced food intake may affect gut hormones and metabolic responses. The aim of this study to determine whether the effect of Ramadan fasting differed in people with DM patients, pre-DM and healthy individuals, with respect to gut hormones, body composition, metabolic parameters, and glycemic control
This research proposal aims to investigate the correlation between a) the hunger feeling as measured by a ten point scale and b) total gastric fluid volumes and content as measured with gastric PoCUS in fasted, healthy subjects > 18 of age, scheduled for elective surgery.
Autophagy, which involves the degradation of aged or damaged cellular components, has been shown to extend healthspan and lifespan in multiple organisms, including flies, worms, and mice. Research has also demonstrated that autophagy declines with age in these simpler experimental models. However, human studies are lacking. Our study seeks to determine whether fasting, a robust stimulus of autophagy, upregulates autophagy in humans, and whether autophagy is reduced in healthy older people compared to healthy younger individuals.
The "CenTEnari" study is a cross-sectional study aiming at suveying the dietary and lifestyle habits of nonagenarians and centenarianss of citizens of the Abruzzo region, Italy.
This study evaluates how Fast Bar(TM), a specially formulated energy bar, when consumed with coffee or tea, affects the physiological condition in participants after an overnight fasting. Participants will fast for 19 hours (Fast Group), consume a Fast Bar in the night (Night Bar Group) or in the morning (Bar+Coffee and Bar+Tea Groups) after an approximately 15-hour overnight fasting. Participants will be assessed for physiological parameters associated with fasting.
