Filter by:The present study aims to measure the impact of consuming a lower sugar flavored water compared to an equal amount of plain water during exercise on selected rehydration markers in healthy children. Participants will complete two experimental visits designed to examine the differentiating effects of one of two selected beverages (1) lower sugar flavored water beverage and 2) plain water) on certain hydration markers and related perceptual variables during repeated bouts of exercise in a warm environment to induce mild dehydration.
Trial Design: This is a feasibility randomised controlled trial. Aim: The study aims to assess the feasibility of conducting a randomised controlled trial using a digital health tool (Keep-On-Keep-Up Nutrition, KOKU-Nut) to improve dietary intake in community-dwelling older adults. Objectives: 1. Is it feasible and practical to run KOKU-Nut study as a powered randomised controlled trial. 2. Adherence to the intervention, motivations, barriers and facilitators of engaging with KOKU-Nut Study population: Community-dwelling adults aged 65 and older Intervention: Participants in the intervention group will be asked to engage with KOKU-Nut at least 3 times a week throughout the 12-week period. A crib sheet and contact details for the research team will be available if participants require additional support to help with technical issues. Control: Participants will continue with usual care and receive a leaflet developed by Age UK about the importance of a healthy lifestyle. Timing and duration 3 month intervention with interviews carried out approximately one week after the intervention period
The investigators want to understand the impact of the body losing and gaining water on brain function. Participants will restrict fluids consumed and exercise to lose 5% of body mass. Participants will then be provided fluid equal to the volume lost to consume over 2 hours (recovery). A series of brain function tests will be performed at baseline, following weight loss, and following recovery.
This is a single-arm prospective study, investigating the feasibility, usability, and safety of a wearable bioimpedance sensor in elderly individuals. The sensor is applied on the upper back of the subject, and will be replaced once weekly. The study will include four phases, each interspersed by an interim analysis. Each phase will have a duration of four weeks.
Acute decompensated heart failure (ADHF) is a complex clinical syndrome caused by cardiac abnormalities compromising the ability of the heart to provide a blood supply adequate to the metabolic needs of peripheral tissues. ADHF is characterized by systemic and pulmonary fluid retention, with weight gain, peripheral edema, needing diuretic therapy. Moreover, ADHF is associated with neurohormonal hyper-activation with enhanced sympathetic nervous and renin-angiotensin-aldosterone systems stimulation, that sustain the vicious circle of cardiac dysfunction and fluid retention. The administration of high doses of diuretics, usually required in ADHF treatment, can induce hypovolemia-induced neurohormonal activation and transient deterioration of kidney function, that, in turn, counteracts the effect of diuretics and limits recovery from fluid overload. The investigators hypothesized that, in patients with ADHF, a more controlled and physiologically-oriented dehydration may blunt diuretic-associated neurohormonal activation, thus providing a safer and more sustained clinical benefit. This controlled dehydration can be achieved by combining furosemide with the RenalGuard System (see The RenalGuard™ System Operator's Manual for specific instructions in setting up and running the device). To date, no data have been provided regarding the potential beneficial effect of this therapeutic strategy in patients with ADHF and fluid overload. Much of the evidences on the use of the RenalGuard system comes from the clinical setting of acute kidney injury (AKI) prevention in patients undergoing intravascular contrast exposure. In this specific field, furosemide-induced high-volume diuresis with concurrent maintenance of intravascular volume through matched hydration, by the RenalGuard System, is now considered by current Guidelines a recommended strategy for AKI prevention in patients with chronic renal failure undergoing coronary interventional procedures. Based on this experience, the investigators will assess the safety and efficacy of this known system capable of delivering intravenous fluid in an amount exactly pre-determined, considering the volume of urine produced by the patient and precisely weighed by the system. This could prevent hypovolemia that may occur in response to high-volume diuresis induced by furosemide. The researchers will perform a spontaneous, prospective, randomized trial aiming at investigating the effect of combined furosemide-induced diuresis and automated matched dehydration, compared with standard furosemide administration in ADHF patients with fluid overload.
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.
Buoy is an all-natural, organic, FDA compliant dietary electrolyte supplement that can be dissolved in 8-12oz water (or other liquid) and provide electrolytes in servings of 1/3 teaspoon. This study will evaluate Buoy in hydrating active adults.
This study aims to evaluate the dehydration and rehydration changes in teeth over time and the quantitative effect of these changes on natural tooth color in the clinic. In addition, it is aimed to evaluate the effectiveness of different color measuring devices used in color detection in the clinic, the use of cross-polarization filters, and white balance calibration in color evaluation. Clinicians will evaluate the results of the time intervals in which dehydration is effective in detectable levels of color change. Considering the quantitative changes in dehydrated and rehydrated teeth, it will be possible to prevent negative results in restorations.
This study will assess the efficacy of Cellular MatrixTM BCT-HA Kit treatment compared to placebo condition on revitalization and skin rejuvenation on the midface. Particular attention will be made to the safety aspects, as well as the histological consequences of treatment.
An epidemic of chronic kidney disease is occurring in laborers who undertake physical work outdoors in hot conditions. The reason for this is largely unknown, but may be related to kidney dysfunction caused by increases in body temperature and dehydration that elicit oxidative stress and inflammation in the renal tubules. The purpose of this study is to determine whether hydration status modifies the development of renal oxidative stress and inflammation.
