PURPOSE OF REVIEW: The intake of water and electrolytes is inseparable from the ingestion of nutrients by normal or artificial means. Recent reports have agreed in criticizing the poor standards of practice and of training in the management of fluid and electrolyte balance, resulting in a large amount of avoidable morbidity, particularly in the elderly [...]
OBJECTIVE: To perform a chemical analysis of all the available waters in Spain with the idea of offering consume recommendations to lithiasic patients. MATERIAL AND METHODS: Information research of the chemical composition of Spanish tap and bottled water in publications, supermarkets and Internet. A descriptive study, and a correlation study between water components by means [...]
In this double-blind crossover study, the effects of bolus infusions of 0.9% saline (NaCl) and Hartmann's solution on serum albumin, haematocrit and serum and urinary biochemistry were compared in healthy subjects. Nine young adult male volunteers received 2-litre intravenous infusions of 0.9% saline and Hartmann's solution on separate occasions, in random order, each over 1h. [...]
Drinking water for approximately one sixth of US households is obtained from private wells. These wells can become contaminated by pollutant chemicals or pathogenic organisms and cause illness. Although the US Environmental Protection Agency and all states offer guidance for construction, maintenance, and testing of private wells, there is little regulation. With few exceptions, well [...]
OBJECTIVE: To compare the treatment of acute intravenous hydration with placebo in term pregnant women manifesting oligohydramnios. METHODS: All patients with oligohydramnios who met the inclusion criteria were offered participation in this randomized, double-blind, placebo-controlled study. After ruling out rupture of membranes and maternal and fetal complications, we recruited 44 women with third trimester singleton [...]
The occupation of firefighting is one that has repeatedly attracted the research interests of ergonomics. Among the activities encountered are attention to live fires, performing search and rescue of victims, and dealing with emergencies. The scientific literature is reviewed to highlight the investigative models used to contribute to the knowledge base about the ergonomics of [...]
Background: Knowledge of the biological variability of the hydration factor (HF), ie, the ratio between total body water and fat-free mass, is important when calculating total body fat by means of the commonly used two-component model, which is based on estimates of body weight and total body water. The effect of pregnancy on the biological [...]
The purpose of this study was to determine the sweat rate and sweat electrolyte composition in female international level soccer players. Thirteen soccer players performed two 90 min soccer-specific training sessions (T1 and T2) on separate days. Hydration status was determined prior to each session and sweat loss, sweat rate and sweat composition (Na (+), [...]
PURPOSE: To investigate the effect of ice slurry ingestion on thermoregulatory responses and sub-maximal running time in the heat. METHODS:: On two separate occasions, in a counterbalanced order, ten males ingested 7.5 g.kg of either ice slurry (-1 degrees C) or cold water (4 degrees C) before running to exhaustion at their first ventilatory threshold [...]
BACKGROUND & AIMS: Bioimpedance spectroscopy (BIS) for the estimation of total body water (TBW) has advantages over isotope dilution techniques, including cost, portability, and ease of use. The aim of the current study was to determine the validity of a BIS device (Imp SFB7) for tracking changes in overfat and obese individuals. METHODS: Sixty overfat [...]
