Human neuropsychology investigates brain-behavior relationships, using objective tools (neurological tests) to tie the biological and behavior aspects together. The use of neuropsychological assessment tools in assessing potential effects of dehydration is a natural progression of the scientific pursuit to understand the physical and mental ramifications of dehydration. It has long been known that dehydration negatively [...]
Protein-energy malnutrition and hypervolemia are major causes of morbidity and mortality in patients on chronic hemodialysis (CHD). The methods used to evaluate nutritional status and volume status remain controversial. Vector bioelectric impedance analysis (vector- BIA) has recently been developed to assess both nutritional status and tissue hydration. The purpose of the study was to assess [...]
The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a disorder of water balance characterized by hypotonic hyponatremia and impaired water excretion. The diagnosis of SIADH is based on the exclusion of other hyponatremic conditions, the presence of hyposmolality with inappropriate urine osmolality and a urine sodium concentration usually above 30 mEq/L. Some simple and [...]
Many diseases have multifactorial origins. There is increasing evidence that mild dehydration plays a role in the development of various morbidities. In this review, effects of hydration status on acute and chronic diseases are depicted (excluding the acute effects of mild dehydration on exercise performance, wellness, cognitive function, and mental performance) and categorized according to [...]
The mode of transmission of Helicobacter pylori, a bacterium causing gastric cancer and peptic ulcer disease, is unknown although waterborne transmission is a likely pathway. This study investigated the hypothesis that access to treated water and a sanitary sewerage system reduces the H. pylori incidence rate, using data from 472 participants in a cohort study [...]
To increase water intake is an useful prophylactic treatment for many urologic diseases, such as urolithiasis or urinary tract infection. An high water intake increases urinary volume with a dilutional effect that involves a consequent decrease of the concentrations of urinary solutes and a reduction of the levels of the salts involved in the lithogenic [...]
Background: The Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate, provided extensive tables of data on total water intake, water intake from beverages and water intake from foods; however, very little information was provided about the specific details of these analyses. Reported total water intake varied with gender and somewhat with age and [...]
Two studies were conducted to investigate gastrointestinal (GI) tolerance of high carbohydrate (CHO) intakes during intense running. The first study investigated tolerance of a CHO gel delivering glucose plus fructose (GLU+FRC) at different rates. The second study investigated tolerance of high intakes of glucose (GLU) vs. GLU+FRC gel. Both studies used a randomized, 2-treatment, 2-period [...]
BACKGROUND AND METHODS: Unusual water intake and drinking behaviour has occasionally been observed in individuals with Prader-Willi syndrome (PWS). The aim of this study is to explore whether this observation is a part of the PWS phenotype and what the consequences may be. The parents of 51 individuals with PWS (age range 2-40 years) were [...]
