Filter by:Approximately 60% of males and 40% of females do not meet current fluid intake recommendations, which is associated with adverse health consequences such as obesity, diabetes, and chronic kidney disease. Newer technologies have been designed to promote fluid intake. "Smart Water Bottles" use mHealth technology to capture fluid intake behaviors automatically and provide cues to encourage fluid consumption. Studies using Smart Water Bottles have helped some individuals increase fluid intake to help reduce kidney stone formation. However, limited research has assessed the efficacy of this technology on improving fluid intake in college students. College is a time with the potential to form healthy habits that carry into adulthood. Previous work has also identified daily changes in morning urine color, thirst perception, and body mass, as simple, inexpensive indicators of daily fluctuations in water balance. Tracking changes in these metrics has the potential to provide participants with evidence of adequate or inadequate fluid consumption. Thus, the combination of prompting from a smart water bottle, as well as daily self-monitoring changes in hydration status, may encourage college students to increase daily fluid consumption.
The primary objective of this study is to analyze smart phone-based Transdermal Optical Imaging (TOI) features to develop a model that can discern hydration status, including: 1) at various timepoints throughout a 24-hour period in healthy adults from the general population (GENPOP), and 2) before and after a team coach-led training session in athletes competing in a sport (ATHLETE). TOI data will be collected alongside standard reference measures of hydration status. In this study each subject will serve as their own control.
The low fluid intake in combination with a high intake of sugar-sweetened beverages (SSB) by children is a significant concern among public health professionals. Therefore reformulation of existing commercially available beverages has been suggested as one of the strategies to change SSB beverage behaviors of children. It has been suggested that lack of flavor in plain water is one of the factors of low water intake in children. Therefore, the addition of a flavor to a low-carbohydrate beverage might increase and facilitate the voluntary fluid intake in children, and result in more effective rehydration during and after exercise. The present study aims to examine if a lower sugar flavored water will improve voluntary hydration in children that perform multiple exercise bouts within a period of 3 hours.
The electrolyte test products are composed of powder and provided in individual stick packs with 5 vitamins including Vitamins B3, B5, B6, B12 and Vitamin C. The products are gluten-, soy-, and dairy-free, and provide electrolytes at concentrations well below the daily value (DV). The DV tells us how much a particular nutrient in a serving of a food product contributes to a daily diet, based on a standard 2000 calorie diet. Despite what the name suggests, this product is taken orally, not intravenously. These packets contain a small percentage of the needed total daily electrolytes but adequate amounts to replace lost electrolytes as a result of physical activity. The products will be consumed following a 90-minute bout of cycling exercise at a moderate intensity of 70-80% max heart rate, at 30-32°C (86-89°F) and 50 ± 5% relative humidity. This same exercise duration and room temperature has been used in a recent study, which also utilized the same body temperature monitoring device as proposed in the present study. The purpose of the exercise bout is to simulate what many individuals are exposed to when exercising in the heat and to moderately dehydrate subjects, as would be the case during a moderate run or cycling event in exercise-trained individuals. Subjects will report to the lab on three separate occasions to consume one of the 3 drinks (hydration multiplier, sugar-free hydration matrix, or water), in random order. The drinks will be consumed during the post-exercise period (30 minutes following the completion of exercise).
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.
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.
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.
Hypernatremic dehydration (HND) is a common and potentially life-threatening condition in children. It is defined by a serum level of sodium greater than or equal to 145 mmol/L . HND is a type of acute dehydration constitutes a medical emergency and requires a rapid diagnosis for adequate and quick management. It is characterized by a deficit of total body water (TBW) relative to total body sodium (TBS) levels due to either loss of free water, or excessive administration of hypertonic sodium solutions. It is common in infants. Net water loss as seen in diarrhea is the most common cause of hypernatremia. Clinical interventions at the hospital settings or accidental sodium loading usually cause hypertonic sodium gain. It is common in developing countries where gastroenteritis is a common problem. Most children with hypernatremia are dehydrated and have the typical signs and symptoms as weight loss, decreased skin turgor, pale skin color, and dry mucous membranes. Hypernatremia, even without dehydration, cause central nervous system symptoms according to the degree of sodium elevation and the acuity of the increase. Patients are irritable, restless weak, and lethargic. Some infants have a high-pitched cry. Alert patients are very thirsty, although nausea and fever may be present. HND can lead to neurological impairment due to brain shrinkage, which can tear cerebral blood vessels, leading to brain hemorrhage. Cerebral hemorrhages are the most serious complications of HND that can eventually lead to convulsions and even coma . The first priority in managing a child with HND is to stop the ongoing water loss by treating the underlying cause. The next step is to restore the intravascular volume with isotonic fluid. Dehydration can be treated with oral, nasogastric, or intravenous fluids. The child is given a fluid bolus, usually 20 mL/kg of the isotonic solution, over about 20 to 30 minutes. More severe dehydration needs repeated boluses at a faster rate. After the fluid bolus is given, the signs of dehydration should be reassessed in order to confirm a complete rehydration. Fluid loss should not be corrected rapidly. Cerebral edema as well as convulsions is serious risks during rapid rehydration, so correction of deficit should be achieved slowly and gradually over 48 hours and should not be decreased to less than 12 mEq/L. To prevent cerebral edema and convulsion, individuals with hypernatremia should be managed in such a way that the reduction rate of serum sodium occurs at approximately 10 to 12 mmol/L/24 hr. Cerebral edema and seizures can be consequences of rapid correction of serum sodium level in these patients in whom the rate of fluid and sodium administration are inappropriate
Diabetic ketoacidosis (DKA) is a common acute complication of type 1 diabetes mellitus (T1DM). DKA is characterized by hyperglycemia, metabolic acidosis, increased levels of ketone bodies in blood and urine. This leads to osmotic diuresis and severe depletion of water and electrolytes from both the intra- and extracellular fluid (ECF) compartments. Estimation of the degree of dehydration for children admitted with DKA is of great clinical importance. The calculation of the amount of deficit therapy depends on the estimated degree of dehydration. However, the degree of dehydration present during DKA is difficult to be clinically assessed. Hyperosmolality tends to preserve intravascular volume with maintenance of peripheral pulses, blood pressure, and urine output until extreme volume depletion occurs. Metabolic acidosis leads to hyperventilation and dry oral mucosa as well as decreased peripheral vascular resistance and cardiac function . consequently, hyper-osmolality may lead to an underestimation of the degree of dehydration, whereas metabolic acidosis may lead to an overestimation of the degree of dehydration. This makes the physical findings unreliable in this setting. Several clinical and biochemical markers were suggested to assess and stage the degree of dehydration at hospital admission. The blood urea nitrogen , hematocrit , plasma albumin are useful markers of the degree of ECF contraction.However, Several previous studies demonstrated that there was no agreement between assessed and measured degree of dehydration which is calculated according to change in body weight at admission and after correction of dehydration. there were tendencies to overestimated or underestimate the degree of dehydration between different physicians. The assessment of the magnitude of dehydration in DKA is of major interest and continues to be a subject of research. This study aims to assess the association between different clinical and laboratory parameters in children with diabetic ketoacidosis and the degree of dehydration at hospital admission among those children.
