This study is being done to examine whether fasting for 13 hours every night is feasible and if it can help breast cancer survivors lose weight and improve their health. - Previous studies have found that women who are overweight or obese when their breast cancer is found (diagnosed) have a greater risk of their breast cancer recurring. Recent research suggests that prolonged nighttime fasting (>13 hours) may improve the risk of recurrence for breast cancer. - This study will examine if fasting for 13 hours per night is doable for participants and will also study what the effect of fasting is on quality of life, mood, fatigue, body size, and markers of health in the blood.
Perioperative fasting remains a common clinical practice in surgical patients to prevent the development of postoperative anesthesia- and surgical-related complications. Clinical observational studies indicated that the combination catabolic effects resulted from prolonged perioperative fasting and profound surgical stress are likely to induce extensive protein catabolism, muscle breakdown and impaired glycemic control during postoperative phase, leading to the development of severe complications. Furthermore, prolonged gastrointestinal fasting is associated with microbial translocation that deteriorates the early recovery after surgery. This clinical trial anticipates in determining the beneficial effect of intraoperative feeding to improve intraoperative hemodynamics and enhance postoperative recovery due to attenuation of systemic catabolism and improvement of insulin sensitivity to glycemic control.
This study will evaluate the effect of short-term fasting (36 hours) in gene expression in blood cells in healthy volunteers.
This study will evaluate the ability of short-term fasting to reduce chemotherapy toxicity and enhance anti-tumour response in patients with colorectal carcinoma subjected to chemotherapy.
Elevated levels of plasma triglycerides are increasingly recognized as an important causal risk factor for cardiovascular disease and associated pathologies. Lowering plasma triglycerides may therefore be a therapeutic target to lower cardiovascular disease risk. With this study the investigators want to examine the effects of fasting on adipose tissue metabolism in humans.
The aim of this work is to evaluate the effect of semi sitting versus supine positions on gastric emptying of fluids in children using gastric ultrasound. The investigators hypothesize that gastric emptying in children might be faster if the patient is in semi-sitting position. This hypothesis could impact the current guidelines for peri-operative fasting. Moreover, if this proved effective, could be used for enhancement of gastric emptying before emergency operations in non-fasting patient.
This study evaluates the perception and compliance with the fasting instructions given to parents of children undergoing surgery. A questionnaire was provided to the parents indicating fasting time requested and actual time of fasting.
Excessive fat in the liver is associated with impairments in metabolic health. Low levels of DNL and high levels of hepatic fat oxidation are considered to be protective. A decrease in glycogen stores has been causally linked to improved whole body fat oxidation. Also on an organ level, it is suggested that hepatic fat oxidation is stimulated by low hepatic glycogen stores. Next to hepatic fat oxidation, DNL may be influenced by hepatic glycogen stores. Some studies have shown that prolongation of fasting time lowers hepatic glycogen content. It is therefore hypothesized that prolonging fasting time will lower glycogen content and thereby increases fat oxidation and decreases DNL in the liver. To this end, hepatic fat oxidation (plasma marker beta-hydroxybutyrate), de novo lipogenesis, hepatic glycogen content and intrahepatic fat content, will be measured upon a short overnight fast and an extended overnight fast in 13 overweight/obese subjects with hepatic steatosis.
Selected patients will be randomised to either hydrocortisone or prednisolone. Each treatment period is of 14 days. Abnormal clinical symptoms, blood glucose and quality of life will be monitored.
