The present study evaluated, using a well-controlled dehydration protocol, the effects of 24 h fluid deprivation (FD) on selected mood and physiological parameters. In the present cross-over study, twenty healthy women (age 25 (SE 0.78) years) participated in two randomised sessions: FD-induced dehydration v. a fully hydrated control condition. In the FD period, the last water intake was betwee...

BACKGROUND Despite exercising in cool environments, ice hockey players exhibit several dehydration risk factors. Individualized fluid plans (IFPs) are designed to mitigate dehydration by matching an individual's sweat loss in order to optimize physiological systems and performance. METHODS A randomized control trial was used to examine IFP versus ad libitum fluid ingestion on hydration in 11 ...

The lifespan of cats with non-obstructive kidney stones is shortened compared with healthy cats indicating a need to reduce stone formation and minimize chronic kidney disease. The purpose of this study was to investigate the effects of increasing dietary polyunsaturated fatty acids (PUFA) on urine characteristics. Domestic-short-hair cats (n = 12; mean age 5.6 years) were randomized into two g...

Purpose. The prevalence of exercise-associated hyponatremia (EAH) has mainly been investigated in male endurance athletes. The aim of the present study was to investigate the prevalence of EAH in female 100-km ultra-marathoners and to compare them to male ultra-runners since females are considered more at risk of EAH. Methods. changes in body mass, hematocrit, [Na+] and [K+] levels in both plas...

Urinalysis is a simple urine analysis performed in many healthcare settings and at home that reveals important diagnostic information. Diabetes mellitus, kidney failure, renal, liver diseases, hydration, urinary tract infection, metabolic abnormalities are among the diseases studied. to perform using test strip, but results must be correctly interpreted. noninvasive, widely available, reasonabl...

OBJECTIVE There is a major problem about the incidence, diagnosis, and differentiation of cerebral salt wasting syndrome (CSWS) and syndrome of inappropriate secretion of antidiuretic hormone (SIADH) in patients with acute central nervous system (CNS) disorders. According to rare reports of these cases, this study was performed in children with acute CNS disorders for diagnosis of CSWS versus S...

The concentrating and diluting mechanisms of the normal kidney contribute in an impressive manner to the defense of water economy. In health, a given amount of solute may be excreted in a widely varying volume of water which is determined under most circumstances by the water needs of the organism. This ability to regulate the osmolality of the urine accounts for a range of urine concentrations...
