Effects of acute dehydration on brain morphology in healthy humans
Dehydration can affect brain structure which has important implications for human health. In this study, we measured regional changes in brain structure following acute dehydration. Healthy volunteers received a structural MRI scan before and after an intensive 90-min thermal-exercise dehydration protocol. We used two techniques to determine changes in brain structure: a manual point counting [...]
Brain apparent diffusion coefficient decrease during correction of severe hypernatremic dehydration
We report on the brain diffusion MR imaging findings in a neonate with severe hypernatremic dehydration, which resulted in cerebral edema (osmotic edema) and in apparent diffusion coefficient decrease, despite a careful and slow rehydration. This report provides in vivo insight into nervous cell response to osmotic challenge. PMID: 16091515 [PubMed - indexed for MEDLINE
Clinical assessment of dehydration in older people admitted to hospital: what are the strongest indicators?
Due to an absence of published primary data, this study explores dehydration prevalence and the change in physiological parameters frequently used to assess dehydration (fluid deficit) in older hospitalized people, as no standard measurement method exists. This observational longitudinal cohort study recruited 43 people aged 60 years or over, voluntarily admitted to a tertiary teaching [...]
Influence of moderate dehydration on soccer performance: physiological responses to 45 min of outdoor match-play and the immediate subsequent performance of sport-specific and mental concentration tests
OBJECTIVE: To determine whether moderate water loss (approximately 1.5-2% of body mass (BM)) represents a significant impairment to soccer match-play and the related fitness variables. METHODS: 11 moderately active male soccer players (mean (SD) age 24.4 (3) years, BM 74.03 (10.5) kg, peak oxygen consumption 50.91 (4.0) ml/kg/min) volunteered to participate. The experimental procedure comprised: [...]
The effects of dehydration on brain volume — preliminary results.
In adults the cranium is a rigid bony vault of fixed size and therefore the intra-cranial volume is a constant which equals the sum of the volume of the brain, the intra-cranial volume of CSF and the intra-cranial volume of blood. There can be marked changes in the volumes of these three intra-cranial compartments which [...]
Return to competition following ischemic colitis caused by severe dehydration
OBJECTIVE: This article summarizes a case of ischemic colitis suffered by a triathlete during an Ironman competition. BACKGROUND: Exercise results in a significant reduction in splanchnic blood flow to help maintain cardiovascular function. When dehydration and heat stress accompany exercise, blood flow to the splanchnic vasculature is further reduced, increasing the risk of local ischemia [...]
Dehydration among long-term care elderly patients with oropharyngeal dysphagia
INTRODUCTION: Long-term care (LTC) residents, especially the orally fed with dysphagia, are prone to dehydration. The clinical consequences of dehydration are critical. The validity of the common laboratory parameters of hydration status is far from being absolute, especially so in the elderly. However, combinations of these indices are more reliable. OBJECTIVE: Assessment of hydration status [...]
Hypernatraemic dehydration in Jamaican breastfed neonates: a 12-year review in a baby-friendly hospital.
A 12-year retrospective review of neonates admitted with hypernatraemic dehydration to the neonatal unit of the University Hospital of the West Indies was conducted between 1 January 1990 and 31 December 2001. Twenty-four infants fulfilled the criteria for hypernatraemic dehydration. Nineteen (79%) women were either nulliparous or primiparous with a mean (SD) age of 26.9 [...]
