Filter by: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.
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.
DETERMINING GASTRIC EMPTYING TIME IN ELDERLY USING ULTRASOUND ASSOCIATED WITH PREOPERATIVE FASTING TIME Background: Gastric contents aspiration is the most crucial complication of general anaesthesia. There are limited studies to assess the gastric volume ultrasound to clarify an appropriate fasting time before surgery. Gastric content will examine after a traditional Turkish breakfast with ultrasound. Methods: After the first ultrasound examination by asking 8 hours fasting ,gastric emptying time(GET) was determined by serial gastric ultrasound examinations with two ultrasonographers and GET identified by real time USG evaluations in every 1 hour. All ultrasound assessments on volunteers will made both in the supine position and right lateral decubitus (RLD) from the epigastric area by using a convex probe. This study is the first one which examine gastric emptying time after a standard Turkish breakfast in over 65 years Turkish population by measuring antral cross section area (CSA) using noninvasive ultrasound.
Undergoing anesthesia requires patients to fast pre-operatively to allow the stomach to empty and prevent aspiration pneumonia but patients are allowed to drink "clear" liquids up to 2 hours before surgery. Clear liquids are defined as water, carbonated sodas, black coffee or tea without milk or sugar, and juices without pulp. Many Americans prefer to take their coffee with half and half or coffee creamer rather than black. This study will determine whether the addition of a small amount of cream to coffee makes any difference to the volume in the stomach after 2 hours. This study will use healthy volunteers as study participants. Each participant will participate in the study 3 times with at least 2 days in between. We will use a bedside ultrasound machine to measure their stomach content volume at baseline and then they will consume one of 3 different prepare drinks - black coffee, coffee with half and half, or coffee with non-dairy coffee creamer. After 2 hours, we will scan their stomach again and measure stomach content volume and compare it to the first measurement. The participants will repeat this two more times on different days so that they would have had a chance to consume all three prepared coffee drinks in a random order.
The study sought to investigate the effects of 16/8 time restricted eating (TRE) with windows of 16 hours of fasting and 8 hours of eating on on body composition, muscle strength, and metabolic factors during resistance training in healthy resistance trained males
In the past, some guidelines advised no oral intake for at least 8 hours before any surgery. However, research has shown risks associated with excessive fasting, such as postoperative insulin resistance, and advantages in shorter fasting protocols, such as reduced postoperative nausea and vomiting. The perioperative fasting guidelines of the European Society of Anaesthesiology focus on preoperative carbohydrates. They hold that it is safe for patients to drink carbohydrate-rich fluids up to 2 hours before elective surgery and that drinking carbohydrate-rich fluids improves subjective well-being, reduces thirst and hunger, and reduces postoperative insulin resistance at an evidence level of 1++. Nevertheless, data on drinking carbohydrate fluids before surgery in elderly patients are limited. In our institution, there are two clinical pathways for total knee arthroplasty according to the surgeons. One difference is whether carbohydrate fluids drink or not before surgery. The purpose of this study, therefore, is to assess gastric volume in fasted elderly patients using ultrasound after they drank carbohydrate fluids 2 hours before surgery and to compare with matched patients using age, body mass index, and comorbidity, who did not drink carbohydrate fluids before surgery.
This study evaluates how Fast Bar(TM), a specially formulated energy bar, affects the physiological condition in participants after an overnight fasting. Participants will fast for 19 hours (Fast Group), consume a breakfast Bar (Breakfast Group) or a Fast Bar(TM) (Fast Bar Group) after an approximately 15-hour overnight fasting. Participants will be assessed for physiological parameters associated with fasting.
The aim of the study is to test a Fasting Mimicking Diet (FMD) for its efficacy on improving muscular resistance and endurance. The investigators will perform a randomized clinical trial to test the efficacy of the FMD on improving muscular strength, muscular resistance and endurance in physically active young adults (18-40 years of age). The study will include two arms: Placebo (Placebo diet) and FMD (3 cycles of 5-day fasting-mimicking diet within two months). Study endpoints will include muscular strength evaluation of lower limbs, cardio-pulmonary responses, neuromuscular function and muscle architecture. Subjects will be evaluated 4 times within 3 months: at baseline (T1), after the 1st cycle of diet (T2), 7 to 15 days after the 3rd cycle of diet maintaining baseline intensity (T3) and with re-assessment of Peak Power Output (T4).
