THREE PERCENT HYPOHYDRATION DOES NOT AFFECT THE THRESHOLD FREQUENCY OF ELECTRICALLY-INDUCED CRAMPS

PURPOSE:: Dehydration is hypothesized to cause exercise-associated muscle cramps (EAMC). The theory states that dehydration contracts the interstitial space thereby increasing the pressure on nerve terminals and cramps ensue. Research supporting this theory is often observational and fatigue is rarely controlled. Inducing cramps with electrical stimulation minimizes many of the confounding factors associated with exercise-induced [...]

HEART RATE RESPONSES AND FLUID BALANCE OF COMPETITIVE CROSS-COUNTRY HANG GLIDING PILOTS

PURPOSE: To evaluate the physiological challenges of competitive cross-country hang gliding. METHODS: Seventeen experienced male pilots (age=41+/-9 y; mean+/-SD) were fitted with a monitor that recorded heart rate and altitude at 0.5 Hz throughout a competitive flight. Fluid losses were evaluated by comparing pilot pre- and postflight mass. RESULTS: The pilots' displacement was 88.4+/-43.7 km [...]

THE ROLE OF HYDRATION IN VOCAL FOLD PHYSIOLOGY

PURPOSE OF REVIEW: Increased vocal fold hydration is a popular target in the prevention and management of voice disorders. Current intervention strategies focus on enhancing both systemic (internal) and superficial (surface) hydration. We review relevant bench and human research on the role of hydration in vocal fold physiology. RECENT FINDINGS: Bench and human studies provide [...]

ANESTHESIA IN PATIENTS WITH ANOREXIA NERVOSA AND BULIMIA NERVOSA

Eating disorders are typical diseases of adolescence and early adulthood. About 1-3% of female juveniles suffer from anorexia nervosa (AN) or bulimia nervosa (BN). Today AN is still the psychiatric disease with the highest mortality rate. The peri-operative mortality rate of patients suffering from AN is in the range up to 15%. The beginning of [...]

INVOLVEMENT OF HOSPITAL NURSES IN CARE DECISIONS RELATED TO ADMINISTRATION OF ARTIFICIAL NUTRITION OR HYDRATION (ANH) IN PATIENTS WITH DEMENTIA: A QUALITATIVE STUDY

BACKGROUND: Nurses that care for patients with advanced dementia are increasingly faced with consequences of disease progression, often requiring them to decide whether to artificially feed these patients. Clarifying how nurses can be better supported in complex care processes involving ethically sensitive decision-making requires that their practice be mapped out. OBJECTIVES: The aims of this [...]

AQUAPORINS IN KIDNEY PATHOPHYSIOLOGY

Seven aquaporin water channels are expressed in human kidneys, and they have key roles in maintaining body water homeostasis. Impairment of their function can result in nephrogenic diabetes insipidus and other water-balance disorders. A lot of data have increased understanding of the functions and mechanisms of regulation of aquaporins both at the molecular and the [...]

REPRODUCIBILITY OF BODY COMPOSITION AND BODY WATER SPACES MEASUREMENTS IN HEALTHY ELDERLY INDIVIDUALS

BACKGROUND AND AIMS : The assessment of body composition and water spaces in elderly persons, especially in disease situations, would be a critical component of the nutritional and hydration management. Bioelectrical impedance analysis (BIA) is a validated bed-side technique for the estimate of total body (TBW) and extracellular (ECW) water. The aim of the present [...]

COMPARISON OF REHYDRATION REGIMENS FOR REHABILITATION OF FIREFIGHTERS PERFORMING HEAVY EXERCISE IN THERMAL PROTECTIVE CLOTHING: A REPORT FROM THE FIREGROUND REHAB EVALUATION (FIRE) TRIAL

BACKGROUND: Performing fire suppression activities results in cardiovascular stress, hyperthermia, and hypohydration. Fireground rehabilitation (rehab) is recommended to blunt the deleterious effects of these conditions. OBJECTIVE: We tested the hypothesis that three rehydration fluids provided after exercise while wearing thermal protective clothing (TPC) would produce different heart rate or core temperature responses during a second [...]

SEX DIFFERENCES IN VOLUNTARY FLUID INTAKE BY OLDER ADULTS DURING EXERCISE

PURPOSE: This study compared the voluntary fluid intake behavior of older men and women (54-70 yr) when provided cold, palatable beverages and ample opportunity to drink between repeated bouts of exercise in the heat. METHODS: Thirteen men and 14 women performed four bouts of 15-min cycling at 65% VO2peak followed by 15 min of rest [...]

OSMOTIC DEMYELINATION SYNDROME

The osmotic demyelination syndrome (ODS) has been a recognized complication of the rapid correction of hyponatremia for decades. However, in recent years, a variety of other medical conditions have been associated with the development of ODS, independent of changes in serum sodium. This finding suggests that the pathogenesis of ODS may be more complex and [...]
