Filter by:The purpose of this study is to determine if drinking proprietary water (PW) during a standardized daily plan as compared to distilled water (control) and carbohydrate-electrolyte (CE) drink can improve hydration status over time. Another purpose is to determine if PW, as compared to control and CE, can improve hydration status, perceptual responses, physiological responses, and cognition measures in a heat stressful environment. Healthy, physically active males and females aged 18 to 50y will be recruited for the study. Participants will be randomized into one of three groups: PW, CE, or Control. The participant will be given a daily standardized plan integrating their assigned fluid into daily hydration habits for five days. Participants will provide their first-morning urine sample, keep a daily food log, and answer questions about their perceptions of hydration. After the five days, they will participate in a treadmill exercise protocol within a warm environment (heat chamber). Multiple physiological, perceptual, and cognitive measures will be obtained while participants exercise and then recover.
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
Dehydration lowers both physical and mental performance if it is severe enough. Performance declines are more pronounced in hot conditions or after prolonged strenuous activity such as exercise. Most individuals drink less than their sweat losses during activity, while some individuals overdrink and develop a sodium deficiency. Water and electrolyte balance must be restored as part of the recovery process after any activity that causes sweating. Plain water causes a decrease in plasma sodium concentration and osmolality, which reduces the desire to drink and increases urine production. Unless the volume ingested exceeds the loss, individuals are in net negative fluid balance throughout the recovery period due to urinary losses. When sodium and potassium are added to rehydration fluids, urine production is reduced in the hours following rehydration. Rehydration is only possible if a volume of fluid equal to or greater than the amount lost through sweat is consumed, together with adequate electrolytes. The test products for this study, TP1 and TP2, are novel hydration beverage formulas. They are an electrolyte drink mixture with five essential vitamins and three times more electrolytes than typical sports beverages. The test products create an osmotic force that permits water to be supplied to the bloodstream sooner in the digestive system by using a specific ratio of sodium, glucose, and potassium. This randomized, placebo-controlled, semi-blind, crossover study will evaluate the effects of the test products on rehydration in healthy adults.
The aim of the clinical trial is to evaluate the efficacy of two novel hydration products on rehydration following exercise.
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.
Greater muscular strength and power are relevant qualities for athletic success and decreased injury rate. It is known that dehydration impairs muscular strength and power, although the explanation for this association is not entirely clear. Besides morphological factors, strength production also depends on neural factors which in turn can be affected by dehydration. Some studies tested the effects of dehydration on neuromuscular function using electromyography (EMG) analysis. However, there is no consensus among those studies. Additionally, exercise may disturb water balance. This can further lead to dehydration if the athlete does not properly rehydrate. In this sense, the scientific evidence has identified people who are considered low drinkers that may be more susceptible to cellular shrinkage, potentially impairing health and performance. Thus, it would be expected that athletes regularly exposed to lower amounts of water intake would have beneficial effects in both performance and health if higher water ingestion was promoted, namely an improved neuromuscular function via enhanced cellular hydration. However, any potential benefit of increasing water intake on neuromuscular function is still to be determined using well-designed experimental studies and state-of-the-art methods. Lastly, there is no consensus regarding the diagnosis of dehydration in athletes. The identification of simple indices to measure dehydration in athletes is crucial as many may be inaccurately diagnosed.
The central hypothesis is that improving hydration through increased water consumption will change the relative abundance of mucolytic bacteria found in the stool. Therefore the specific aims are 1) to quantify intervention effects on fecal microbiota relative abundance and plasma lipopolysaccharide binding protein, 2) observe the effects of the intervention on bowel frequency and signs/symptoms of gastrointestinal stress, and 3) to investigate relations between executive function and hydration status.
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 purpose of this study was to determine if rapid changes in hydration status could be determined by urine color expressed in CIE color space
The purpose of this study is to investigate the ability of a wearable bioimpedance sensor to detect mild dehydration in healthy volunteers following the administration of Furosemide. In addition, the study will investigate changes in bioimpedance related to normal variation in tissue hydration (circadian changes, skin thickness, posture, and moderate activity). The study will also provide information on the durability of the sensor.
