OBJECTIVE To assess the efficacy of interventions and environmental factors on increasing fluid intake or reducing dehydration risk in older people living in long-term care facilities. DESIGN Systematic review of intervention and observational studies. DATA SOURCES Thirteen electronic databases were searched from inception until September 2013 in all languages. References of included papers...

Background: dehydration fever is a common problem during the first week of life. This study aimed to compare the characteristics of neonates with fever due to dehydration and healthy infants. Methods: This cross-sectional study was performed on 324 neonates including 120 neonates with normal body temperature and 204 neonates with fever due to dehydration (hyperthermia) referred to Ghaem Hospit...

  A male neonate from a 23 year-old mother by cesarean section without complication in labor or delivery had vomiting from birth for 9 days and lost 400 grams of body weight. He had severe dehydration upon admission to our hospital. After treating his dehydration and assessment of his problem by laboratory tests and radiography we found that he had esophageal atresia without hypoglycemia. We re...

this paper investigates hollow and porous alumina nanospheres that were previously synthesized to be used for the dehydration of methanol to dimethyl ether (dme). as hollow nanostructures possess characteristics such as low density and high surface to volume ratio, their catalytic activity between hollow and porous structure is compared. for this purpose, three most important parameters (acidit...

introduction: a growing number of muslim athletes now engage in international competition. this raises the question of the advice they should be given if a major event occurs during the month of ramadan. methods: a narrative review has been based upon books and extensive reviews completed by the author and other investigators. results: practical considerations hamper assessment of the effects o...

introduction: unstained formalin-fixed whole brain specimens and brain slices do not give satisfactory results for teaching neuroanatomy. in addition, difficulties in obtaining human brains for dissection have increased the demand for more durable brain specimens that have been obtained by the plastination technique. in the present study brain specimens were sliced, fixed and stained using the ...

Clinical medicine defines dehydration using blood markers that confirm hypertonicity (serum sodium concentration ([Na+])>145 mmol/L) and intracellular dehydration. Sports medicine equates dehydration with a concentrated urine as defined by any urine osmolality (UOsm) ≥700 mOsmol/kgH2O or urine specific gravity (USG) ≥1.020. Objective To compare blood versus urine indices of dehydration in a c...

Angiotensin (Ang) type 1a (AT1a) receptors are critical in the control of blood pressure and water balance. Experiments were performed to determine the influence of dehydration on brain Ang receptors and plasma vasopressin (VP) in mice lacking this receptor. Control or AT1a knockout (AT1aKO) male mice were give water ad libitum or deprived of water for 48 hours. Animals were anesthetized with h...
