Children Rehydration During Exercise
Dehydration in ChildrenThe 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.
Effects of Two Novel Hydration Beverage Formulas on Rehydration in Adults
DehydrationThe 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).
Effects of Hydration Changes on Neuromuscular Function of Athletes
DehydrationHyperhydrationGreater 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.

Boluses of Ringer's in Surgical Kids (BRiSK Study)
Dehydration in ChildrenFluid TherapyTraditional 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.
Quantitative Evaluation of the Effect of Dehydration and Rehydration Levels on Tooth Color
Tooth DiscolorationThis 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.
Prevelane and Short Term Outcome of Hypernatremic Dehydration in Children With Acute Gastroenteritis...
Gastroenteritis AcuteHypernatremic 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
Clinical and Laboratory Parameters Associated With Different Degrees of Dehydration Among Children...
Diabetic KetoacidosisDiabetic 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.
Sensor-Assisted Prevention of Dehydration in Head and Neck Cancer Patients
Head and Neck CancerThe 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.
