Since its first description in 1985, two opposing theories have evolved to explain the etiology of symptomatic hyponatremia of exercise. The first holds that the condition occurs only in athletes who lose both water and sodium during exercise, and fail to fully replace their sodium losses. The second theory holds that the symptomatic form of [...]

The purpose of this research is to ascertain nursing home (NH) staffs' perspectives of the problem of dehydration in NHs (skilled nursing facilities) and have them identify clinically practical interventions to ensure that NH residents consistently take adequate fluids. Four focus groups with 28 NH staff members in attendance are held in three NHs in [...]
To investigate the mechanisms controlling human gallbladder contraction, especially to determine the role of neural factors, the gallbladder response to various stimuli was evaluated in eight normal subjects using realtime ultrasonography. In addition, plasma cholecystokinin (CCK) levels were measured using a region-specific antibody (OAL 656). Intramuscular injections of CCK-8 and of cerulein induced mean maximal [...]

During exercise, sweat output often exceeds water intake, producing a water deficit or hypohydration. The water deficit lowers both intracellular and extracellular fluid volumes, and causes a hypotonic-hypovolemia of the blood. Aerobic exercise tasks are likely to be adversely effected by hypohydration (even in the absence of heat strain), with the potential affect being greater [...]
