Five trained men were studied during 2 h of cycling exercise at 67% peak oxygen uptake at 20-22 degrees C to examine the effect of fluid ingestion on muscle metabolism. On one occasion, the subjects completed this exercise without fluid ingestion(NF) while on the other they ingested a volume of distilled deionized water that prevented [...]
BACKGROUND: Detection of estrogens in the environment has raised concerns in recent years because of their potential to affect both wildlife and humans. OBJECTIVES: We compared exposures to prescribed and naturally occurring estrogens in drinking water to exposures to naturally occurring background levels of estrogens in the diet of children and adults and to four [...]
This Position Stand provides guidance on fluid replacement to sustain appropriate hydration of individuals performing physical activity. The goal of prehydrating is to start the activity euhydrated and with normal plasma electrolyte levels. Prehydrating with beverages, in addition to normal meals and fluid intake, should be initiated when needed at least several hours before the [...]
Dehydration secondary to acute gastroenteritis is a commonly encountered condition among patients presenting to physicians' offices and hospital EDs. Treatment options consist of oral rehydration therapy (ORT), intravenous rehydration therapy (IVRT) and subcutaneous rehydration therapy (SCRT). Although most patients with dehydration can be effectively treated in an outpatient setting, hospitalization is frequently warranted, with estimated [...]
OBJECTIVES: Vocal fold hydration is purported to promote optimal biomechanical characteristics of vocal fold mucosa, increase efficiency of vocal fold oscillation, and enhance voice quality. The purpose of this work was to determine the magnitude and consistency of the effect of vocal fold hydration on vocal fold function across published clinical studies. METHODS: We completed [...]
Early postnatal life is a period of active functional reorganization and cutaneous physiological adaptation to the extrauterine environment. Skin as the outermost organ of mammalians is endowed of multiple functions such as protection, secretion, absorption and thermoregulation. Birth stimulates the epidermal barrier maturation and the skin surface acidification especially in premature infants. In full-term infants [...]
BACKGROUND: With the current practice of using estimated glomerular filtration rate (eGFR) for the assessment of renal function, serum urea is arguably a redundant test. However, with little evidence, it is purported that urea can be used as a marker to aid in the assessment of hydration status. The aim of this study was to [...]
The goal of this study was to instrumentally evaluate the skin of healthy infants and to compare it to adult skin. A total of 70 infants, 45 girls and 25 boys, ages 8-24 months, and 30 healthy women were studied by means of transepidermal water loss (TEWL), capacitance, and pH measurements at two different skin [...]
Primary cerebral vasculitis in children is a newly recognized, rare inflammatory condition affecting the vessels of the brain. It is characterized by newly acquired neurological deficit(s) with angiographic or histological evidence of central nervous system (CNS) vasculitis, in the absence of other known diseases with these findings. MATERIAL AND METHODS: We performed a retrospective review [...]
BACKGROUND: Contrast-induced nephropathy is the leading cause of in-hospital acute renal failure. This side effect of contrast agents leads to increased morbidity, mortality, and health costs. Ensuring adequate hydration prior to contrast exposure is highly effective at preventing this complication, although the optimal hydration strategy to prevent contrast-induced nephropathy still remains an unresolved issue. Former [...]
