OBJECTIVE: To investigate the state of hydration in infants during the weaning period in dry and hot climates in the center of Iran. METHODS: Using a refractometer, 162 urine specific gravity (USG) was measured from 400 infants, between 4 to 6 months old. They were chosen among infants who visited the primary clinics in the [...]

BACKGROUND: Older adults are at increased risk of dehydration, yet water balance is understudied in this population. OBJECTIVE: This controlled diet study assessed the effect of age on water input, output, and balance in healthy adults. Hydration status (plasma osmolality and urine specific gravity) and body composition were also measured. DESIGN: Eleven men and 14 [...]

All cultures dictate the need to feed the hungry and create rituals for almost every life passage around the consumption of food and beverage. Yet, in old age and among those who cannot advocate for themselves, mealtime is medicalized and demoted to an insignificant event without dignity or regard for individualized needs. Attention must be [...]

Because dehydration (DEH) violates assumptions used in the assessment of body composition, hydration testing has become an integral part of minimal weight (MW) assessment. PURPOSE: To determine the accuracy of hydration tests for the detection and quantification of hypertonic DEH. METHODS: Twenty-five male collegiate wrestlers (mean +/- SD, age: 20.0 +/- 1.4 yr, height: 175.0 [...]

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 [...]

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 [...]
