OBJECTIVES: To assess effects of dehydration on tooth colour. To investigate any change in tooth colour resulting from dehydration and the time required for any change to return to baseline. METHODS: 20 subjects with intact maxillary central incisors were recruited. In each case one incisor was randomly assigned as test tooth with the other acting [...]
Good fluid intake in children is vitally important as they have immature thirst mechanisms, relatively high rates of fluid loss and are physically active. Poor fluid intake may affect children's cognitive functioning as well as bladder control. Research shows that children drink seven times as much soft drink as water. Schools have a vital role [...]
The purpose of this study was to examine 1) wildfire fighters' ability to consume the prescribed fluid volume (1200Â mLÂ h(-1)), 2) the effect of fluid intake on plasma sodium and hydration, and 3) the effect of fluid intake on firefighters' heart rate, core temperature and activity during emergency suppression shifts. METHODS: Thirty-four firefighters were divided into [...]
Background: Early identification and treatment of dehydration is prudent in patients requiring home parenteral nutrition (HPN) or home intravenous fluids (HIVF) to prevent hospital admissions for dehydration. Our home nutrition support service (HNS) developed a protocol in 2010 to provide additional bags of HIVF to be kept on hand for immediate use in patients identified [...]
Background/objectives: Post-exercise hypotension (PEH) is a sustained reduction in mean arterial blood pressure (MAP) after prolonged exercise. As water drinking is known to elicit a large acute pressor response, we aimed to explore the effect of drinking water during exercise on PEH. Subjects/methods: Ten normotensive male volunteers performed the control protocol: 30 min supine rest, 60 min [...]
PURPOSE: Dry axilla can sometimes be found among dehydrated older patients. In this study, we measured the axillary moisture and assessed it as possible marker for dehydration. METHODS: Twenty-nine older patients admitted with acute medical conditions participated in this study. Dehydration was diagnosed by the calculated serum osmolality of greater than 295mOsm/L. The moisture of [...]
In elite soccer, players are frequently required to play consecutive matches interspersed by 3 days and complete physical performance recovery may not be achieved. Incomplete recovery might result in underperformance and injury. During congested schedules, recovery strategies are therefore required to alleviate post-match fatigue, regain performance faster and reduce the risk of injury. This article [...]
No matter how mild, dehydration is not a desirable condition because there is an imbalance in the homeostatic function of the internal environment. This can adversely affect cognitive performance, not only in groups more vulnerable to dehydration, such as children and the elderly, but also in young adults. However, few studies have examined the impact [...]
Chronic kidney disease is common and associated with significant morbidity. Given the high risk of cardiovascular morbidity and mortality in patients with chronic kidney disease, it is important to identify and treat related risk factors. However, there is growing uncertainty about the benefits of some recommended treatment targets.The National Kidney Foundation's Kidney Disease Outcomes Quality [...]
