Neuropsychological performance, postural stability, and symptoms after dehydration.
CONTEXT: Dehydration and concussion are common in athletic performance. Some experts have speculated that dehydration may negatively influence performance on tests commonly used for concussion assessment. OBJECTIVE: To determine how the signs and symptoms, neuropsychological performance, and postural stability are affected by dehydration. DESIGN: Repeated-measures design assessing subjects in the euhydrated and dehydrated conditions.Setting: Sports [...]
Is the prevalence of dehydration among community-dwelling older adults really low? Informing current debate over the fluid recommendation for adults aged 70+years.
OBJECTIVE: The fluid recommendation for adults aged 70+ years has been criticised on the basis of a low prevalence of dehydration in community-dwelling older adults. This study explores whether the low prevalence might reflect limitations of individual dehydration indices. DESIGN: Cross-sectional data on plasma sodium, blood urea nitrogen (BUN), creatinine, glucose and potassium were used [...]

Effect of exercise-induced dehydration on lactate parameters during incremental exercise.
Cyclists often use heart rate limits or power output zones, obtained from lactate parameters during incremental exercise testing, to control training intensity. However, the relationship between heart rate or power output, and blood lactate can be changed by several factors including dehydration. Therefore, in the current study we investigated the impact of exercise-induced dehydration on [...]
Urine specific gravity and other urinary indices: inaccurate tests for dehydration.
OBJECTIVE: Urine output, specific gravity, and ketones (urinary indices) are commonly used as an objective means to assess for dehydration and gastroenteritis severity; however, their utility has not been established. The study was designed to evaluate the accuracy of urinary indices as diagnostic tests to identify acute dehydration. METHODS: We completed a prospective cohort study [...]
Dehydration and heat-related death: sweat lodge syndrome
A 37-year-old Caucasian male died of dehydration and heat exposure following a sweat lodge ceremony in outback Australia. The case demonstrates difficulties that may arise in the determination of the cause of death at autopsy due to nonspecific pathologic findings in hyperthermic deaths. There are also a number of features that characterize this particular "sweat [...]
Impact of an early weighing policy on neonatal hypernatraemic dehydration and breast feeding
AIMS: To ascertain the effect of a policy of early weighing on the detection and severity of neonatal hypernatraemic dehydration (NHD) and on breastfeeding rates in the short and medium term. METHODS: A policy of weighing infants at 72-96 h was introduced from 1 July 2004. Two time periods were studied: pre-policy and post-policy (18 [...]

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 [...]
