INTRODUCTION Rheumatoid arthritis (RA) is a chronic disease causing recurring inflammatory joint attacks. These attacks are characterized by macrophage infiltration contributing to joint destruction. Studies have shown that RA treatment efficacy is correlated to synovial macrophage number. The aim of this study was to experimentally validate the use of in vivo superparamagnetic iron oxide nanop...

AIMS To examine body composition in preterm infants. METHODS Body composition was measured by dual energy x-ray absorptiometry (DEXA) at hospital discharge, term, 12 weeks, and at 6 and 12 months corrected age in 125 infants (birthweight < or = 1750 g, gestational age < or = 34 weeks). RESULTS Body weight derived by DEXA accurately predicted that determined by conventional scales. In both s...

We validated whole body composition estimates from dual-energy X-ray absorptiometry (DEXA) against estimates from a four-component model to determine whether accuracy is affected by gender, race, athletic status, or musculoskeletal development in young adults. Measurements of body density by hydrostatic weighing, body water by deuterium dilution, and bone mineral by whole body DEXA were obtaine...

An increase in femoral and tibio/fibular bone mass following periosteal membrane stimulation by Moloney sarcoma virus inoculation into thigh muscles of mice was measured in situ on formalin fixed excised hind limbs using a Hologic 4500A Fan Beam X-ray bone densitometer adapted for small bone samples. These results were verified by measurements of constant dry bone mass of the same bones liberat...

We would like to thank the DEXA 2002 Workshop General Chair (Professor Roland Wagner) and the organizing committee of the 13th International Conference on Database and Expert Systems Applications (DEXA 2002) for their support and their cooperation. Many thanks go to Ms. Gabriela Wagner for providing a great deal of assistance. We are very indebted to all program committee members and external r...

We examined the relationship between body fat and body mass index (BMI) in a multiethnic population of obese children. BMI z-scores were compared to DEXA measures of whole body composition and regional fat distribution. Fat mass index (FMI) was best predicted by the equation: 1/[(0.159- 0.013 x percentile of total abdominal fat)- (0.01 x BMI z-score)], where percentile of abdominal fat ranges f...

Background Smart scales are increasingly used at home by patients to monitor their body weight and composition, but scale accuracy has not often been documented. Objective The goal of the research was determine 3 commercially available smart for composition compared with dual x-ray absorptiometry (DEXA) as gold standard. Methods We designed a cross-sectional study in consecutive evaluated DEXA ...

INTRODUCTION Scientific studies indicate that there is a correlation between decreased bone mineral density and the age of the patient, especially in post menopausal women. GOAL The aim of our study was to assess the connection between osteoporosis and the age of respondents, based on the DEXA findings in patients with calcium urolithiasis. MATERIAL AND METHODS The study was prospectively a...

BACKGROUND Body composition assessment in patients with chronic renal failure is of paramount importance since studies have demonstrated the association of protein-energy malnutrition with an increased morbidity and mortality in this population. However, practical and sensible indicators of body compartments are still needed for clinical purposes. Thus, we aimed to evaluate the simple methods o...
