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 [...]
BackgroundnnLow concentrations of albumin in serum and long gastric emptying times have been returned to normal in dogs by salt and water restriction, or a high protein intake. We aimed to determine the effect of salt and water balance on recovery of gastrointestinal function after elective colonic resection in human beings.nMethodsnnWe randomly allocated ten patients [...]
The airway mucus in patients with cystic fibrosis (CF) is dehydrated and adhesive and accumulates in the airways, resulting in chronic inflammation, infection, and progressive loss of lung function. Inhaled mannitol improves mucus clearance and, when administered over 2 weeks, it improves lung function in CF (Jaques et al. Chest. 2008;133(6):1388-1396). The changes in the [...]
Aim. Extensive research has been undertaken in the area of exercise and hydration. Most work has focused on prehydration. Less is known about different fluid intake patterns during exercise and its effect in thermoregulatory variables in hot environments. This study attempted to determine if ingesting fluid either in a single bolus or intermittently during exercise [...]
Previous researchers have not investigated the thermoregulatory responses to multiple consecutive days of American football in adolescents. OBJECTIVE: To examine the thermoregulatory and hydration responses of high school players during formal preseason football practices. DESIGN: Observational study. SETTING: Players practiced outdoors in late August once per day on days 1 through 5, twice per day [...]
