Sex difference of urinary osmolality in German children.

BACKGROUND/AIMS: Origin ofÂ sexÂ differenceÂ inÂ urinaryÂ osmolality. METHODS: In 495 healthyÂ childrenÂ aged 4.0-14.9 years participating in the DONALD (Dortmund Nutritional and Anthropometric Longitudinally Designed) study (247 boys, 248 girls), the water intake recorded in 24-hour weighed dietary records along withÂ urinaryÂ volume,Â osmolalityÂ and free water reserve in 24-hour urine samples from the same day as the dietary record were determined. RESULTS: Boys showed [...]

Influence of raised osmolarity on clinical outcome after acute stroke.

BACKGROUND AND PURPOSE: Abnormal physiological parametersÂ afterÂ acute strokeÂ may induce early neurological deterioration. Studies of the effect of dehydration onÂ strokeÂ outcomeÂ are limited. We examined the association ofÂ raisedplasma osmolality onÂ strokeÂ outcomeÂ at 3 months and the change of plasma osmolality with hydration during the first weekafterÂ stroke. METHODS: Acute strokeÂ patients had their plasma osmolality measured at admission and at days 1, 3, [...]

Effects of Ramadan upon fluid and food intake, fatigue, and physical, mental, andsocial activities: a comparison between the UK and Libya.

Two studies were performed duringÂ Ramadan, one in theÂ UKÂ (N=31) and the other inÂ LibyaÂ (N=33). The aims were to assess some changes to lifestyle that are produced by fasting as well asÂ effectsÂ due to culture. Subjects were studied on eight separate occasions: four control days (two before and two afterÂ Ramadan) and four days during the four weeks ofÂ Ramadan itself. [...]

Urine colour as an index of hydration in critically ill patients

In order to test the hypothesis thatÂ urineÂ colourÂ can be used as anÂ indexÂ ofÂ hydrationÂ inÂ criticallyÂ illÂ patients, we selected 40 intensive care and high-dependencyÂ patientsÂ and correlatedÂ urineÂ colourÂ (scored on an eight-point scale) with various indices ofÂ hydration:Â urine:plasma sodium, osmolality and urea ratios,Â urineÂ output and central venous pressure. In addition, we compared theÂ colour-chart score with scores made by intensive care nurses (without the benefit of aÂ colourÂ chart) in [...]

Effect of sodium in a rehydration beverage when consumed as a fluid or meal.

To investigate the impact of fluid composition on rehydration effectiveness, 30 subjects (15 men and 15 women) were studied during 2 h of rehydration after a 2.5% body weight loss. In a randomized crossover design, subjects rehydrated with water (H2O), chicken broth (CB: 109.5 mmol/l Na, 25.3 mmol/l K), a carbohydrate-electrolyte drink (CE: 16.0 mmol/l [...]

Dehydration in the elderly: a short review.

DehydrationÂ is the most common fluid and electrolyte problem among theÂ elderly. The usual causes of water loss are frequently absent in dehydratedÂ elderlyÂ patients. Age-related changes in total body water, thirst perception, renal concentrating ability, and vasopressin effectiveness probably predispose toÂ dehydration.Â DehydrationÂ related to infection, high-protein tube feedings, cerebral vascular accidents, and medication-related hypodypsia are particularly relevant forÂ elderlypatients. Appropriate treatment [...]

Fluid and electrolyte balance in ultra-endurance sport.

It is well known that fluid and electrolyte balance are critical to optimal exercise performance and, moreover, health maintenance. Most research conducted on extreme sporting endeavour (>3 hours) is based on case studies and studies involving small numbers of individuals. Ultra-endurance sportsmen and women typically do not meet their fluid needs during exercise. However, successful [...]

Dehydration: biological considerations, age-related changes and risk factors in older adults

Maintenance of water balance is essential to normal physiologic function and vigorous aging.Â OlderÂ adults, however, frequently experience alterations in fluid homeostasis, which result inÂ dehydration. This article describes the physiology of water balance,Â age-relatedÂ changesÂ that influence fluid regulation, and associatedÂ riskÂ factorsÂ forÂ dehydrationÂ inÂ olderÂ adults. Fluid hygiene is an important health promotion activity for this age group, but when efforts to prevent imbalance are [...]

Effects of solution osmolality on absorption of select fluid replacement solutionsin human duodenojejunum.

These experiments examined relationships between initial osmolality and carbohydrate (CHO) composition of an infused solution and osmolality and water and CHO absorption in a test segment. A triple-lumen tube with a 10-cm mixing segment and a 40-cm test segment was passed into the duodenojejunum. The infusion port was approximately 10 cm beyond the pyloric sphincter. [...]

Human hydration indices: acute and longitudinal reference values.

It is difficult to describe hydration status and hydration extremes because fluid intakes and excretion patterns of free-living individuals are poorly documented and regulation of human water balance is complex and dynamic. This investigation provided reference values for euhydration (i.e., body mass, daily fluid intake, serum osmolality; M +/- SD); it also compared urinary indices [...]
