Drinking water is associated with weight loss in overweight dieting women independent of diet and activity.

BACKGROUND: Data from short-term experiments suggest thatÂ drinkingÂ waterÂ may promoteÂ weightÂ lossÂ by lowering total energy intake and/or altering metabolism. The long-term effects ofÂ drinkingÂ waterÂ on change in bodyÂ weightÂ and composition are unknown, however. OBJECTIVE: This study tested for associations between absolute and relative increases inÂ drinkingÂ waterÂ andÂ weightÂ lossÂ over 12 months. METHODS AND PROCEDURES: Secondary analyses were conducted on data from the Stanford A TO ZÂ weightÂ lossÂ intervention [...]

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 [...]

Bioelectrical impedance analysis in the assessment of hydration status in peritoneal dialysis patients.

Objective: Assessment of fluid status in chronic peritoneal dialysis (PD) patients is complex. Clinical evaluation based solely on body weight, blood pressure, volume of ultrafiltration (UF) and peripheral edema is insufficient. A non-invasive test, bioelectrical impedance analysis (BIA) might be of potential benefit. Aim: To test whether BIA correlates with other ancillary markers of extracellular [...]

Comparison of Ringers Lactate vs Normal Saline in Children with Acute Diarrhea and Severe Dehydration: A Double Blind Randomized Controlled Trial.

OBJECTIVE: WHO recommends Ringers lactate (RL) and Normal Saline (NS) for rapid intravenous rehydration in childhood diarrhea and severe dehydration. We compared these two fluids for improvement in pH over baseline during rapid intravenous rehydration in children with acute diarrhea. DESIGN: Double-blind randomized controlled trial. SETTING: Pediatric emergency facilities at a tertiary-care referral hospital. INTERVENTION: [...]

Hydration and cognitive performance.

A clinical link exists between severe dehydration andÂ cognitiveÂ performance. Using rapid and severe water loss induced either by intense exercise and/or heat stress, initial studies suggested there were alterations in short-term memory andÂ cognitiveÂ function related to vision, but more recent studies have not all confirmed these data. Some studies argue that water loss is not responsible for [...]
