Filter by:The goal of this clinical trial is to compare betaine supplementation to placebo in firefighters undergoing live burn training regarding thermoregulation and inflammation. The main questions it aims to answer are: - Does betaine supplementation mitigate rises in core temperature during firefighter live burn training? - Does betaine supplementation decrease inflammation from firefighter training? - Does betaine supplementation increase total body water stores? Participants will supplement with betaine for 1 month and complete: - Total Body Water measures - Body Composition measures - Live Burn training with Core Temperature Measurements - Provide Salivary samples
Dehydration is commonplace in a number of settings, including exercise, daily living (i.e. inadequate fluid intake) and with relatively common bacterial/viral infections that induce diarrhoea and/or vomiting. As such, it is important to develop effective strategies to facilitate the recovery and maintenance of body water (i.e. rehydration). Whilst rehydration from exercise dehydration has been well-studied, rehydration from other types of dehydration have not. Despite this, oral rehydration solutions have been produced and are commercially available (in chemists/pharmacies and supermarkets) to help recover from dehydration produced by illnesses like diarrhoea and vomiting. Most commercially available oral rehydration solutions use a sugar-base (glucose) and a mixture of electrolytes, but little work has gone into evaluating the efficacy of such solutions. Furthermore, more recent work has explored the use of proteins that they may offer some advantage over sugar/glucose-based beverages. Therefore, the aim of this study is to investigate the efficacy of a protein-based oral rehydration solution compared to two current commercially available glucose-based oral rehydration solutions.
Traditional protocols for intravenous fluid administration in children who have undergone a major abdominal or thoracic operation are based on a landmark paper published in 1957 by Holliday and Segar. The basic tenets include: (1) Continuous intravenous fluid administration; (2) Total fluid volume based on the "4:2:1" rule; (3) Use of hypotonic electrolyte solutions, most commonly 0.45% sodium chloride (NaCl) + 20 milliequivalents per liter (mEq/L) potassium chloride (KCl); and (4) Inclusion of 5% dextrose to increase the osmolarity of the infusate and to help prevent ketosis and acidemia.
The primary aim of this study is to assess cardiovascular changes (blood pressure, heart rate, electrocardiogram/ECG) in response to mild fluid-restriction dehydration and subsequent rehydration in healthy young and old people. Secondary aims are to assess changes in body composition, mood, and hunger in response to mild dehydration and rehydration.
Water is largest single component to the human body and is requisite for numerous essential metabolic processes. Dehydration refers to deficient body water content and is prevalent in healthcare. It has been repeatedly shown that dehydration is associated with increased mortality and morbidity. Despite its prevalence and deleterious sequelae, there is substantial deficiency in the knowledge, assessment and management of this pathological state: there is no internationally-recognised definition, clinical signs can be subtle and unreliable, and there is no objective marker with everyday clinical utility. As a consequence, diagnosis of dehydration and prompt rehydration strategies are often poorly delivered in healthcare environments. Thirst plays an integral part in body water homeostasis. Plasma osmolality will increase with uncompensated water loss and is considered the most reliable surrogate objective marker of dehydration. Increased osmolality is sensed by hypothalamic osmoreceptors stimulating thirst and pituitary secretion of antidiuretic hormone (ADH). Thirst has been shown to be sensitive to small changes in plasma osmolality and shows little intra-individual variation. In view of this, it is rational to propose tendering control of intravenous rehydration to patients, enabling them to use the finely-honed intrinsic thirst mechanism to guide their own fluid therapy. A recent pilot study demonstrated that healthy subjects, when allowed to regulate their own intravenous fluid therapy in response to thirst intensity, rehydrated themselves more efficiently than subjects receiving a guideline-based, clinician-delivered fluid regimen. What is unclear is the extent of the reliability of thirst in guiding intravenous fluid rehydration therapy. The investigators propose a double-blinded, repeated measures study in which healthy volunteers are dehydrated using exercise-heat stress in a climatic chamber. Once dehydrated by 3-5% of their body weight, subjects will receive intravenous fluid rehydration which they can demand in response to their sensation of thirst. In one arm of the study they will receive low volume fluid bolus on demand, and in the other arm they will receive a higher volume fluid bolus. Thirst scores and surrogate markers of dehydration will be measured throughout this process. The investigators can then assess whether the demand for additional fluid in response to thirst reduces in frequency in proportion to the degree of correction of fluid deficit.
The goal of this research study is to learn if home-use of devices to identify dehydration risk, when added to standard care, will help to lower hospitalizations and emergency room visits (and related costs) in patients with head and neck cancer. CYCORE is a software-based system that enables comprehensive collection, storage and analysis of information related to cancer research and clinical care. In this study, those in the CYCORE group use devices at home to measure their dehydration risk. This information is monitored by their clinicians. Those in the standard care group complete health based surveys, as do those in the CYCORE group.
