Filter by:Adult Muslims are obliged to start fasting during the month of Ramadan. Fasting entails refraining from all food, drink, tablets and injections(vitamins & fluids) between sunrise and sunset; a period which varies by geographical location and season. People with type 1 Diabetes are among those who are risky to fast this holy month in the Muslim faith and thus are exempted from fasting. Yet many patients fast in spite of medical advice and religious exemption and for those patients, healthcare professionals should provide the utmost care and continuous diabetes education. Different diabetes education modalities exist like DSME (Diabetes self-management education with proven efficacy. One modality is the Diabetes Conversation Map which delivers diabetes education interactively through a series of maps that address different issues in diabetes management and includes a specially designed Ramadan map. In this study, two modalities of Diabetes focused Ramadan education will be compared regarding aiding patients to fast Ramadan safely. One modality will be Diabetes conversation maps and the other the International Diabetes Federation Education modules.
Participants will undergo one day of habitual eating followed by 36 hours of water only fasting and final day of habitual eating of the exact same diet consumed on the first eating day. Blood draws will be performed on Day 1 in a 10-12 hr fasted state and 2 hour postprandial state and again on Day 3 in a 36hr fasted state and a 2 hour post prandial state. Microbiome samples and blood glucose data will be collected throughout the course of the study.
According to normal physiology, the longer fasting period allows food particles to pass stomach through small intestines to minimize intragastric content. The practice guidelines recommend 2-hour fasting period for clear fluid (including water, pulp-free juice and tea or coffee without milk), 4- hour fasting period for breast milk and 6-hour fasting period for non-human milk and solid food to reduce risks of pulmonary aspiration. As a result of longer fasting period, patients tend to experience preoperative dehydrated states and intraoperative hypotension. Patients' demographic data will be obtained from charts. Parents will be asked for type, volume of fluid/food intake and NPO time. This study will be done at BCH's Gastroenterology Procedure Unit (GPU) theaters to measure actual intragastric volume and pH at the beginning esopagogastroduodenoscopy procedures. We hope to demonstrate the relationship between NPO time and actual intragastric volume which provide sufficient data of NPO time to ensure patient's safety.
This study aims at assessing whether breath acetone concentration is a good bio-marker of instantaneous energy balance in healthy subjects.
This study will examine the effect of eating timing on body composition. Previous studies have shown that restricting food intake to 8 hours a day can result in losses in body fat and an up-regulation of fat use. The purpose of this study is to assess changes in body composition when the eating window time is from 6am-2pm vs 2pm-10pm. Hypothesis: The 2-10pm eating window will result in significantly greater changes in body composition (i.e. decreased fat mass) and the 2pm-10pm window will result in better adherence. Methods: Body composition (fat and lean mass) will be assessed by air displacement densitometry (Bod Pod). Measures will be made over 4 weeks (pre-) and (post) dietary treatment. Adherence will also be assessed by a questionnaire to determine the ease/difficulty of the treatment.
Historically, adults and children who undergo elective surgery remain fasting in the preoperative period, for the purposes of avoiding bronchial aspiration of the gastric contents during general anesthesia. The determination of preoperative fasting has taken on importance only in 1946, when Mendelson established a relationship between pulmonary aspiration during labor and general anesthesia. Stemming from other studies, such concept has been expanded to elective surgery and 25 ml were set as the maximum threshold of the gastric content to thus reduce the hazards of aspiration pneumonia. The fasting time prescribed is still the subject of several investigations. For decades it has been established that patients should not feed on solids or ingest liquids over a period of 8 to 12 hours prior to surgery. The guidelines are well set in connection with the rules of fasting, with aims at making the instructions constant throughout different services worldwide. In 2011, the American and the European guidelines became more permissive and determined as safe the 2 hours for liquids devoid of residue, 4 hours for breast milk, 6 hours for infant formula and non-human milk, 6 hours for light meals, and 8 hours for full meals. In accordance with the American guideline, liquids devoid of residue are: water, fruit juice with no pulp, carbohydrate-based beverages, tea with no residue, and black coffee, but those examples are not extensive. Gelatin is solid prior to intake, but it is found in a liquid state inside the stomach and, therefore, it is regarded as a liquid devoid of residue. Yet, in spite of the non-human milk's being a liquid material, it features a gastric emptying time which is similar to that of the non-fat solids. A light meal is characterized by toast and liquids devoid of residue, whilst a full meal includes food that is fried or which contains a high level of fat. Currently, many directives (American Society of Anaesthesiologists - ASA; Norwegian National Consensus Guideline - NNCG; Association of Anaesthetists of Great Britain and Ireland - AAGBI) recommend liquids devoid of residue until two hours prior to the anesthetic induction for elective surgery in healthy children. The particular benefit of the oral intake of fluids includes a lower incidence of deleterious effects, such as thirst, irritation, crying, hypoglycemia, and dehydration. The preservation of the intravascular volume improves the hemodynamic conditions during the induction of inhalation anesthesia and facilitates the vascular access. Even though the old instruction of "nothing by mouth after midnight" is in a process of being replaced by shorter periods of fasting, both surgeons and anesthesiologists still deem the traditional fast indispensable and have trouble with implementing the new norms, either by uncertainty before the possibility of the catastrophic consequences of pulmonary aspiration, or by lack of update on the subject. That matter generates mistakes in the rendering of information by the health professionals. Combined with the unawareness of the guardians in respect of the risk of bronchial aspiration and the anxiety in relation to the fasting, there is a result of difficulty in abidance by the proper preoperative fasting. The minority of the guardians understands the real importance of the preoperative fasting and, many times, food regarded as "harmless" is offered during the period of fasting. Likewise, the guardians provide improper information in order to maintain the surgical procedure, with no regard for the correct observance of the fasting. That way, countless pediatric elective surgeries are canceled, deriving in psychological, social, and economic implications. The correction of these flaws will allow for the anesthetic procedure to take place in a more secure manner, with the proper observance of the fasting period and with the least possible trauma to the child.
Prospective comparative cohort study including 159 pregnant women at the third trimester recruited from the antenatal clinic at EL-Demerdash outpatient clinic, and followed up during the holy month of Ramadan (from 18th June To 16th July 2015). The patients recorded their pattern of fasting during Ramadan then grouped into three groups A, B, C regarding fasting state A- Non fasting group B- Partially fasting group C- Totally fasting group
The primary aim of this study is to examine the effect of fructose ingestion on serum FGF-21 levels in humans.
Effectiveness of fasting or fasting-mimicking diet has been proved an effective approach to treat metabolic and autoimmune diseases in mice. However, clinical trials performing prolonged fasting with more than 7 days have not been reported. Investigators conduct an open label, phase I/II clinical trial to evaluate the safety and effectiveness of the 21-day fasting-like diet in the treatment of metabolic and autoimmune diseases.
The investigators want to establish a new model of acute febrile disease by mimicking the conditions seen in hospitalized patients in regards to inflammation, immobilisation and fasting. In this new model of disease, healthy young adults will be given lipopolysaccharide (LPS) to induce endotoxemia and inflammation/fever and then fast and bedrest for 36 hours. Glucose, fat and protein metabolism will be investigated using clamp technique and tracer methodology together with intracellular signalling pathway activation in muscle and fat biopsies. This new model of disease will later be used in another study to investigate different protein supplement´s effect on muscle waste during acute febrile disease.
