Dysphagia, Nutrition, and Hydration in Ischemic Stroke Patients at Admission and Discharge from Acute Care.

Dysphagia may predispose stroke patients toward undernutrition and hydration. These comorbidities increase patient risks for reduced functional outcome and short-term mortality. Despite this impact, available information on relationships among dysphagia, nutrition, and hydration status in acute stroke is limited and conflicted. This study evaluated nutrition and hydration status in ischemic stroke patients with versus without [...]

The hypertonic state.

Evolution has provided an elaborate network of regulatory systems that stabilize body-fluid volume, temperature and composition. This stability insulates cells from an ambient hostile world and assures them the best possible conditions in which to function optimally. When one of these regulatory systems fails, cells and even whole organ systems cannot function properly. This paper [...]

French children start their school day with a hydration deficit.

Background and Aims: Fluid requirements of children vary as a function of gender and age. To our knowledge, there is very little literature on the hydration status of French children. We assessed the morning hydration status in a large sample of 529 French schoolchildren aged 9-11 years. Methods: Recruited children completed a questionnaire on fluid [...]

Plasma volume changes with movement to supine and standing positions.

The chronology of hemoconcentration and hemodilution associated withÂ changesÂ in posture, and the reliability of venous hematocrit (Hct), hemoglobin (Hb), andÂ plasmaÂ proteins (PP) as indicators in evaluatingÂ changesÂ inÂ plasmaÂ volumeÂ were determined in seven male subjects. Red cell mass was also measured by the CO method at the termination of the erect andÂ supineÂ positions.Â Movementto and fromÂ supineÂ and erectÂ positionsÂ produced consistent, rapid, and progressiveÂ changesÂ in Hct, Hb, [...]

Body weight changes in child and adolescent athletes during a triathlon competition.

We examined young athletes during a triathlon performed in a hot climate. Complete or partial data were available for 95 athletes competing in the National Triathlon Championship in Costa Rica. Mean Â± SD for age and body weight (BW) were 13.1 Â± 2.5 years and 46.3 Â± 11.5 kg, respectively. Race requirements included: 500 m [...]

The effect of beverages varying in glycaemic load on postprandial glucose responses, appetite and cognition in 10-12-year-old school children.

Reducing glycaemic index (GI) and glycaemic load (GL) inconsistently improves aspects of cognitive function and appetite in children. Whether altering the GL by lowering carbohydrate relative to protein and fat has a role in these effects is unknown. Therefore, we assessed the differential effects of beverages varying in GL and dairy composition on appetite, energy [...]

Analysis of dehydration and strength in elite badminton players.

BACKGROUND. The negative effects of dehydration on aerobic activities are well established. However, it is unknown how dehydration affects intermittent sports performance. The purpose of this study was to identify the level of dehydration in elite badminton players and its relation to muscle strength and power production. METHODOLOGY: Seventy matches from the National Spanish badminton [...]

Effect of Preexercise Soup Ingestion on Water Intake and Fluid Balance During Exercise in the Heat.

PURPOSE: To determine whether chicken noodle soup before exercise increases ad libitum water intake, fluid balance, and physical and cognitive performance compared with water. METHODS: Nine trained men (age: 25Â±3y; VO2peak: 54.2Â±5.1mlÂ·kg-1Â·min-1; meanÂ±SD) performed cycle exercise in the heat (Wet Bulb Globe Temperature=25.9Â±0.4ÂºC) for 90min at 50% VO2peak, 45min after ingesting 355ml of either commercially-available [...]

Hydration status and fluid and sodium balance in elite Canadian junior women’s soccer players in a cool environment.

Dehydration can impair mental and on-field performance in soccer athletes; however, there is little data available from the female adolescent player. There is a lack of research investigating fluid and electrolyte losses in cool temperatures. Therefore, the purpose of this study was to investigate the pretraining hydration status, fluid balance, and sweat sodium loss in [...]

Relationship between thirst perception and plasma arginine vasopressin concentration in man.

We examined the possibility that measurements of thirst perception in man using the visual Analogue Scale (VAS) can be used to estimate plasma arginine vasopressin concentration in man. In thirty normal subjects (male=15 and female=15), thirst perception (TP, cm) was rated and 5.0ml blood samples were collected for the measurement of plasma arginine vasopressin (PAVP) [...]
