Ramadan observance requires a total abstention from food and drink from sunrise to sunset for a period of one month. Such intermittent fasting has only minor effects upon the overall nutrition and physiological responses of the general sedentary population. Larger meals are consumed at night and in the early morning. Body mass usually remains unchanged, [...]
This study determined the fluid balance of elite female basketball players before and during competition. Before and during two international games seventeen national level players (age: 24.2 ± 3 y; height: 180.5 ± 6 cm; mass: 78.8 ± 8 kg) were assessed. Fluid balance assessment included pregame hydration level as determined by urine specific gravity [...]
Hydration and nutrition are essential for the maintenance of life. In patients at the end of life, artificial hydration and nutrition pose clinical, ethical, and logistical dilemmas. No strong evidence exists supporting the use of parenteral hydration/nutrition for the majority of terminally ill patients; however, a subset of patients may derive some benefit. Uncertainty about [...]
OBJECTIVE: WHO recommends Ringers lactate (RL) and Normal Saline (NS) for rapid intravenous rehydration in childhood diarrhea and severe dehydration. We compared these two fluids for improvement in pH over baseline during rapid intravenous rehydration in children with acute diarrhea. DESIGN: Double-blind randomized controlled trial. SETTING: Pediatric emergency facilities at a tertiary-care referral hospital. INTERVENTION: [...]
Ensuring that the nutrition and hydration needs of patients in hospital are met is part of the nurse's role. Adequate nutrition and hydration is vital for good health, from both a physical and psychological perspective, and should be considered a priority by nurses. Actions required by nurses may include addressing potential barriers and obstacles that [...]
Background: Patients admitted to surgery may be dehydrated, which is difficult to diagnose except when it is severe (>5% of the body weight). We hypothesized that modest dehydration can be detected by kinetic analysis of the blood hemoglobin concentration after a bolus infusion of crystalloid fluid.Methods:Four series of experiments were performed on 10 conscious, healthy [...]
Objective: It is purported that exercise-induced dehydration (EID), especially if ≥ 2% bodyweight, impairs endurance performance (EP). Field research shows that athletes can achieve outstanding EP while dehydrated > 2% bodyweight. Using the meta-analytic procedure, this study compared the findings of laboratory-based studies that examined the impact of EID upon EP using either ecologically valid [...]
In the absence of any food or fluid intake during the hours of daylight during the month of Ramadan, a progressive loss of body water will occur over the course of each day, though these losses can be completely replaced each night. Large body water deficits will impair both physical and cognitive performance. The point [...]
Hypernatremia is common in intensive care units. It has detrimental effects on various physiologic functions and was shown to be an independent risk factor for increased mortality in critically ill patients. Mechanisms of hypernatremia include sodium gain and/or loss of free water and can be discriminated by clinical assessment and urine electrolyte analysis. Because many [...]
Hyponatremia associated with diarrhea is usually caused by dehydration, with salt loss accompanying the excessive loss of water. On the other hand, hyponatremia in this setting can occasionally be caused by excess ingestion or administration of hypotonic fluids (1, 2). In this report, we describe the differential diagnosis of hyponatremia in an infant.
