22 Clinical Trials for Various Conditions
The presence of certain ingredients such as sodium and glycerol can facilitate retention of the fluid consumed via renal water reabsorption. To maintain overall whole-body fluid balance, it is important that ingested fluid is retained in the body instead of losing it through urination. The purpose of this study is to determine the effect of sodium and glycerol concentrations at various fluid intake volumes on fluid balance in healthy, euhydrated men and women.
The results of a prior study PEP-2311 suggested there was a positive dose-response effect of glycerol and sodium on fluid balance and fluid retention. In addition, inclusion of glycerol resulted in an upward shift in the relationship between sodium concentration and fluid balance. The practical interpretation is that addition of glycerol enables a reduction in sodium concentration compared with a 0% glycerol drink. In this follow-up study, the investigators hypothesize that 1) fluid balance will be sustained (greater than or not different from baseline) and significantly greater than placebo for 120 min after drinking the test no/low/moderate carbohydrate beverages and 2) fluid balance will not differ between the carbohydrate-electrolyte beverages, but both will be greater than placebo.
The objective of this study is to determine the effect of consumption of drinks with varying amounts of glycerol and electrolytes on fluid balance at rest.
This pilot study will examine the benefit of this amino acid based hydration solution in patients with IBD who have undergone a total colectomy and have either ileostomies or jpouches. Findings from this study and possible future studies could have broad implications for patients with malabsorption resulting from many underlying conditions, including IBD.
The specific aim of this study is to gather data on fluid balance, intravenous medication administration, electrolyte balance, and diuretic and dialysis use in patients with acute respiratory failure who might benefit from a strategy designed to limit fluid administration.
Sepsis is a common inflammatory response to infection characterized by hypovolemia and vasodilation for which early administration of intravenous fluids has been suggested to improve outcomes. The ideal fluid balance following initial resuscitation is unclear. Septic patients treated in the intensive care unit commonly receive significant volumes of intravenous fluids with resultant positive fluid balance for up to a week after their initial resuscitation. Observational studies have associated fluid receipt and positive fluid balance in patients with severe sepsis and septic shock with increased mortality but are inherently limited by indication bias. In order to determine the optimal approach to fluid management following resuscitation in patients with severe sepsis and septic shock, a randomized controlled trial is needed. The primary hypothesis of this study is that, compared to usual care, a conservative approach to fluid management after resuscitation in patients with sepsis and cardiopulmonary dysfunction will increase intensive care unit free days.
The purpose of the APEX study is to determine whether carbohydrate-electrolyte beverage intake promotes fluid balance during exercise in the heat compared with water or placebo intake.
This study is about investigating the relationship of postoperative fluid balance, inflammation and acute kidney injury. This is a non-interventional study (no drug administration). The investigators will collect baseline demographic data, postoperative fluid balance status by Intake-output data, follow routine labs and collect 1 blood sample (0.5ml) with morning lab draws on day 1 and 5ml urine samples on day 1 and 2.
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 primary purpose of the proposed study is to evaluate the effects of a topical sodium bicarbonate lotion (PR Lotion, AMP Human, Park City, UT) on measures of hydration status and fluid balance in humans when exposed to the heat while resting and during light/moderate aerobic exercise. A secondary purpose is to examine these same effects with two differing dosage patterns of the lotion. A tertiary purpose is to investigate the effect of an amino acid rehydration beverage in comparison to a placebo on measurements of hydration, subjective assessments of stress, and vestibular as well as musculoskeletal measures of fatigue for up to 24-hours after the completion of both passive and exertional heat stress within a dehydrated state.
The purpose of this research study is to evaluate the effects of a topical sodium bicarbonate lotion on physiological and psychological responses associated with hydration status and fluid balance in humans during passive heat stress. Currently, the ingestion of sodium has been an effective measure for improvements in fluid regulation and hydration status in humans. However, the investigators do not know its regulatory relationship with measurements of fluid balance when supplemented through the skin.
The investigators hypothesize that 1. an acute treatment of low-dose aspirin will lead to a) decreased resting platelet activation, platelet aggregation, and clotting potential, b) increased fibrinolytic potential following fire fighting, c) no significant effect on endothelial function or arterial stiffness versus the placebo condition. 2. chronic treatment with low-dose aspirin will lead to a) decreased resting and fire fighting induced platelet activation, platelet aggregation, clotting potential, b) increased fibrinolytic potential, and c) increased endothelial function and decreased arterial stiffness in response to live fire fighting versus the placebo condition. 3. short-term fire fighting activity will result in: a) a reduction in arterial function (reduced endothelial function, increased augmentation index and an attenuated arterial stiffness response); b) a disruption in hemostasis that is characterized by an increase in platelet number and function, an increased coagulatory potential and altered fibrinolytic potential; and c) an elevation in procoagulatory cytokines, systemic inflammation, monokine chemoattractant protein, and matrix metalloproteinases.
The purpose of this study is to determine whether an intravenous salt solution called "Plasmalyte" causes less abnormality of the body's acid levels than a solution called "Normal Saline."
It is well established that post-exercise rehydration with electrolyte solutions is more effective than plain water. However, most commercially available drinks are high in electrolytes but lack some essential trace minerals. This study aims to examine the impact of a higher-electrolyte sports drink compared with a low-electrolyte, trace-mineral-rich solution and water on the time course and extent of rehydration after exercise-induced dehydration.
The "beverage hydration index" (BHI) assesses the hydration potential of any consumable fluid relative to water. The BHI is a relatively new metric. Our purpose was to assess the BHI of beverages never previously tested, including an amino acid-based oral rehydration solution (AA-ORS), a glucose-containing ORS (G-ORS) and a sports drink (SD) compared to water (control).
The purpose of this study is to collect information about what happens to certain chemicals produced in the body called hormones during respiratory infections such as bronchiolitis. Bronchiolitis is an infection of small airways in the lungs caused by a virus. This infection, which causes swelling and injury in the lungs, is commonly seen in infants and children less than 2 years of age.
This observational study evaluates the impact of high and low chloride containing IV fluids on administrative and clinical outcomes. The study uses a large electronic health dataset and examines patients receiving fluid replacement and resuscitation. The hypothesis is that high chloride solutions are associated with adverse outcomes as measured by administrative data and by clinical parameters.
The objectives of this multicenter pragmatic clinical trial are to compare the effectiveness and relative safety of balanced fluid resuscitation versus 0.9% "normal" saline in children with septic shock, including whether balanced fluid resuscitation can reduce progression of kidney injury.
Many patients with traumatic brain injuries (including strokes, blood clots, or other brain injuries) are given concentrated salt water solutions (hypertonic saline) in order to treat brain swelling (cerebral edema). Current therapies consist of a mixture of sodium and chloride, which can lead to high levels of serum chloride and increased total body water. High levels of chloride can cause acidosis, which can cause the body to function sub-optimally. Therefore, the investigators are proposing to use two concentrated solutions in these patients at the same time that will allow for a lower total volume of solution administration and reduce the rise in chloride to prevent acidosis. The main outcome will therefore be the patients sodium level, chloride level and serum pH.
The objective of this pilot study is to assess overall feasibility prior to embarking on a larger randomized pragmatic trial comparing the clinical effectiveness of fluid resuscitation with NS versus LR for pediatric patients with suspected septic shock. Necessary feasibility assessments include ensuring appropriate compliance with study fluid in each of the two arms, effectiveness of study enrollment using a pragmatic study design embedded within routine clinical practice, and acceptability of using Exception from Informed Consent (EFIC).
The investigators are developing two new medical instruments: 1. the Intelligent Sensor Belt (ISB), and 2. the Body Composition and Hydration Status Analyzer (BC-HS-A). ISB serves the purpose of measuring calorie/ energy consumption of the human body during physical activity. The BC-HS-A measures the body composition, i.e. the fat and lean body mass and the hydration status i.e the amount of water inside and outside of the body cells. The goal of this pilot study is to obtain data from the investigators prototype medical instruments: 1. ISB, and 2. BC-HS-A during physical exercise and compare those results with readings of other commercially available instruments or exercise equipments. The investigators would be testing for technical feasibility and, through comparison with existing measuring devices, the reliability of the investigators prototype.
The purpose of this study is to determine the safety and efficacy of lixivaptan in the treatment of hyponatremia in patients with congestive heart failure.
