INTRODUCTION: Service members with traumatic amputations may be at an increased risk of elevated core body temperature, since their ability to dissipate heat may decrease with the reduction in body surface area (BSA) after injury. Elevated core temperature can impair physical performance during combat operations potentially putting the service members and their teams at risk. The purpose of this study was to compare core temperature between individuals with and without amputations during a prolonged endurance event...

Our aim was to determine short and medium-term changes of neutrophil gelatinase-associated lipocalin (NGAL) in the urine of patients undergoing shock wave lithotripsy (SWL). In patients with kidney stones, serum urea and creatinine (Cr), urine Cr and NGAL levels were determined immediately before and at 3, 24 h and 30 days after SWL. Urine NGAL concentrations were normalized to urinary Cr ruling out the confounding effect of variable hydration states. Thirty-five patients with a single renal stone were enrolled...

The purpose of this study was to compare markers of hydration during sub-maximal exercise and subsequent time trial performance when consuming water (PW) or coconut water (CW). There was also a secondary aim to assess the palatability of CW during exercise and voluntary intake during intense exercise. 10 males (age 27.9 + 4.9 years, body mass 78.1 + 10.1kg, average max minute power 300.2 + 28.2W) completed 60-min of sub-maximal cycling followed by a 10-km time trial on two occasions. During these trials participants consumed either PW or CW in a randomised manner, drinking a 250 ml of the assigned drink between 10-15 min, 25-30 min and 40-45 min, and then drinking ad libitum from 55-min until the end of the time trial...

The aim of this pilot study was to assess body composition and total energy expenditure (TEE) in 35 obese 7-9 years old Kuwaiti children (18 girls and 17 boys). Total body water (TBW) and TEE were assessed by doubly-labeled water technique. TBW was derived from the intercept of the elimination rate of deuterium and TEE from the difference in elimination rates of (18)O and deuterium. TBW was used to estimate fat-free mass (FFM), using hydration factors for different ages and gender. Fat mass (FM) was calculated as the difference between body weight and FFM...

Runners are unlikely to consume fluid during training bouts increasing the importance of recovery rehydration efforts. This study assessed urine specific gravity (USG) responses following runs in the heat with different recovery fluid intake volumes. Thirteen male runners completed 3 evening running sessions resulting in approximately 2,200±300 mL of sweat loss (3.1±0.4% body mass) followed by a standardized dinner and breakfast. Beverage fluid intake (pre/post-breakfast) equaled 1,565/2,093 mL (low; L), 2,065/2,593 mL (moderate; M) and 2,565/3,356 mL (high; H)...

K Tangvoraphonkchai, A Davenport
BACKGROUND/OBJECTIVES: Patients with chronic kidney disease treated by haemodialysis (HD) are at increased risk of sarcopenia. Bioelectrical impedance spectroscopy (BIS) can be used to determine body composition, and is one of the several potential screening tools for sarcopenia. The newer generation of portable hand-held devices can be readily used in dialysis centres. The results from BIS devices using a two-compartmental model of body composition can be affected by hydration status and so ideally measurements should be made when patients are not overhydrated...

A 60-year-old man initially presented with pain in the right upper quadrant in October 2010. A computed tomography (CT) scan of the abdomen pelvis completed at that time showed a mass at the junction of the body and tail of the pancreas and multiple large liver lesions. A CT-guided liver biopsy revealed low-grade neuroendocrine carcinoma. The patient was initially started on systemic treatment with sunitinib (Sutent) and octreotide. He developed intolerable side effects, including nausea and migraine. Therapy was discontinued in October 2011, when a CT scan revealed evidence of disease progression...

BACKGROUND: Optimizing body composition for healthy aging in the community is a significant challenge. There are a number of potential interventions available for older people to support both weight gain (for those who are underweight) and weight loss (for overweight or obese people). While the benefits of weight gain for underweight people are generally clearly defined, the value of weight loss in overweight or obese people is less clear, particularly for older people. OBJECTIVES: This umbrella review aimed to measure the effectiveness of nutritional interventions for optimizing healthy body composition in older adults living in the community and to explore theirqualitative perceptions...

The assessment of body composition has important applications in the evaluation of nutritional status and estimating potential health risks. Bioelectrical impedance analysis (BIA) is a valid method for the assessment of body composition. BIA is an alternative to more invasive and expensive methods like dual-energy X-ray absorptiometry, computerized tomography, and magnetic resonance imaging. Bioelectrical impedance analysis is an easy-to-use and low-cost method for the estimation of fat-free mass (FFM) in physiological and pathological conditions...
