Hydration and independence in activities of daily living in people with multiple sclerosis: a pilot investigation.

We investigated whether an athlete's self-chosen nutrition strategy (A), compared with a scientifically determined one (S), led to an improved endurance performance in a laboratory time trial after an endurance exercise. S consisted of about 1000Â mLÂ·h(-1) fluid, in portions of 250Â mL every 15Â min, 0.5Â g sodiumÂ·L(-1), 60Â g glucoseÂ·h(-1), 30Â g fructoseÂ·h(-1), and 5Â mg caffeineÂ·kg body mass(-1). Eighteen [...]

Hydration Status of Arabic Adolescents and Young Men: Measurement, Evaluation, and a School-based Initiative to Improve Drinking Behaviour.

BACKGROUND. Despite the importance of hydration, limited research has been undertaken in Arabic populations. METHODS: Study 1: 88 adult military cadets and 32 school-based adolescents provided five sequential daily mid-morning urine samples. Hydration thresholds were produced using percentiles of estimated urine osmolality (Uosm) and urine color (Ucol). Study 2: 120 military cadets and 52 adolescents [...]

Influence of Beverage Temperature on Palatability and Fluid Ingestion During Endurance Exercise: a systematic review.

BACKGROUND. Beverage palatability is known to influence fluid consumption during exercise and may positively influence hydration status and help to prevent fatigue, heat illness and decreased performance. PURPOSE: The aims of this review were to evaluate the effect of beverage temperature on fluid intake during exercise and investigate the influence of beverage temperature on palatability. [...]

Effect of exercise-induced dehydration on endurance performance: evaluating the impact of exercise protocols on outcomes using a meta-analytic procedure.

Objective: It is purported that exercise-induced dehydration (EID), especially if â‰¥ 2% bodyweight, impairs endurance performance (EP). Field research shows that athletes can achieve outstanding EP while dehydrated > 2% bodyweight. Using the meta-analytic procedure, this study compared the findings of laboratory-based studies that examined the impact of EID upon EP using either ecologically valid [...]

Hypernatremia in critically ill patients.

Hypernatremia is common in intensive care units. It has detrimental effects on various physiologic functions and was shown to be an independent risk factor for increased mortality in critically ill patients. Mechanisms of hypernatremia include sodium gain and/or loss of free water and can be discriminated by clinical assessment and urine electrolyte analysis. Because many [...]

Urine osmolality. A definitive test of renal function.

The ability of the kidneys to concentrate urine is regarded as a sensitive indicator of renal function.1Â Since concentration tests are easily done, they enjoy wide clinical use. This renal activity is usually studied by measuring urine specific gravity, i.e. the ratio of the weight of urine to an equal volume of water. The specific gravity [...]

Improving nutrition and hydration in hospital: the nurse’s responsibility.

Ensuring that the nutrition and hydration needs of patients in hospital are met is part of the nurse's role. Adequate nutrition and hydration is vital for good health, from both a physical and psychological perspective, and should be considered a priority by nurses. Actions required by nurses may include addressing potential barriers and obstacles that [...]

Effects of hydration and water deprivation on blood viscosity during a soccer game in sickle cell trait carriers.

The present study compared the changes in blood viscosity, hydration status, body temperature and heart rate between a group of sickle cell trait (SCT) carriers and a control (Cont) group before and after a soccer game performed in two conditions: one with water offered ad libitum (hydration condition; Hyd) and the other one without water [...]

Is there a role for parenteral nutrition or hydration at the end of life?

Hydration and nutrition are essential for the maintenance of life. In patients at the end of life, artificial hydration and nutrition pose clinical, ethical, and logistical dilemmas. No strong evidence exists supporting the use of parenteral hydration/nutrition for the majority of terminally ill patients; however, a subset of patients may derive some benefit. Uncertainty about [...]

Physical signs of dehydration in the elderly.

Objective Dehydration is a common condition and frequent cause of hospitalization in older people, despite the caregiver's high attention in attempt to avoid its occurrence. In this study, various physical signs were examined as clinical signs of dehydration in elderly. Methods A prospective observational study was conducted in an acute care teaching hospital. Consecutive elderly [...]
