Hydration status in college football players during consecutive days of twice-a-day preseason practices.
BACKGROUND: Football players lose 3.5 to 5 kg of body weight during preseason practices because of heavy sweating. This fluid may be difficult to replace when practices occur 2 times per day on consecutive days. HYPOTHESIS: Football players are hypohydrated during twice-a-day preseason training in a hot, humid environment. STUDY DESIGN: Descriptive laboratory study. METHODS: [...]
EFFECT OF MATERNAL ORAL HYDRATION ON AMNIOTIC FLUID INDEX IN WOMEN WITH PREGNANCY-INDUCED HYPERTENSION.
OBJECTIVE: To evaluate the effect of maternal oral hydration on amniotic fluid index (AFI) in women with pregnancy-induced hypertension. METHODS: Five women with pregnancy-induced hypertension and five normotensive gravidae at 32-37 weeks gestation with normal AFI (8-18cm) were hydrated by oral intake of 2L of water over 1 h. Both groups were similar in age, [...]
HYDRATION FOR TREATMENT OF PRETERM LABOUR.
BACKGROUND: Hydration has been proposed as a treatment for women with preterm labour. Theoretically, hydration may reduce uterine contractility by increasing uterine blood flow and by decreasing pituitary secretion of antidiuretic hormone and oxytocin. OBJECTIVES: To evaluate the effectiveness of intravenous or oral hydration to avoid preterm birth and its consequences in women with preterm [...]

Physiology and pathophysiology of the vasopressinergic system.
Arginine vasopressin, a hypothalamic peptide hormone, has multiple physiological functions, including body water regulation, control of blood pressure and effects on body temperature, insulin release, corticotropin release, memory and social behaviour. These functions are achieved via at least three specific G-protein-coupled vasopressin receptors. Development of specific vasopressin receptor antagonists in recent years is helping to [...]
EFFECT OF ORAL AND INTRAVENOUS HYDRATION ON OLIGOHYDRAMNIOS.
OBJECTIVE: To investigate whether oral or intravenous hydration affects oligohydramnios in cases with normal biophysical profile scores. STUDY DESIGN: One hundred twenty-four gravidas with singleton pregnancies at or near term were identified during a 16-month period retrospectively as having oligohydramnios. A total of 50 subjects with normal biophysical profiles (8 of 10) whose labor was [...]
Aquaporin-related disorders of water homeostasis.
The discovery of four major water channels in the kidney, namely aquaporins (AQP) 1, 2, 3 and 4, has allowed a substantial increase in our understanding of renal water regulation in health and disease. This review discusses the renal aquaporin water channels in the urinary dilution and concentrating defects in cardiac failure, cirrhosis, syndrome of [...]
