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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
Background and aims: Spinal cord injured patients may be adversely affected by disturbances of nutritional status, particularly malnutrition and fat mass overload. Malnutrition increases the risk for development of pressure sores, and fat mass excess increases the cardiovascular and respiratory risks of these patients, as well as predisposing to the development of diabetes mellitus, pressures [...]
CONTEXT: The protective equipment worn during American football has been shown to increase thermal strain; however, the perception of this increased heat has not been examined. OBJECTIVE: To evaluate perceptual responses of American football players while wearing different uniforms during exercise in the heat and to evaluate how these responses may be used to monitor [...]
