Calf circumference: clinical validation for evaluation of muscle mass in the elderly.

CONCLUSION: CC can be used as a measure for early identification of muscle mass decrease in routine evaluations of the elderly in primary care. PMID: 29412289 [PubMed - in process]

Conclusions: Osteoporosis in CF occurs with deteriorating clinical status while the role of calcium metabolism seems minor. Gender specific and dysglycemic impact on bone status should be investigated further. PMID: 29780417 [PubMed]

Objective: The clinical consequences of insulin resistance and hyperinsulinemia on marrow lipid remain elusive. We aimed to explore the effects of anthropometric and biochemical measures, that is, estimates of insulin resistance, on marrow lipid accumulation in nondiabetic postmenopausal women using magnetic resonance (MR) spectroscopy. Methods: The study participants were 91 nondiabetic postmenopausal women. Marrow fat fraction (FF) at the L3 vertebral body by single-voxel MR spectroscopy and bone mineral density (BMD) by dual-energy x-ray absorptiometry were measured. Their glucose and lipid metabolism were determin...

In this study, we investigated the association between NAFLD and sarcopenia in elderly patients. Methods: We classified the participants into sarcopenia/nonsarcopenia groups based on dual-energy X-ray absorptiometry (DXA), muscle strength (grip strength), or/and physical performance (6 m usual gait speed). We diagnosed NAFLD by ultrasonography combined with the history of alcohol intake. Logistic regression analysis was used to assess the correlation between sarcopenia and NAFLD. Results: NAFLD was significantly less frequent in the sarcopenia group than in the nonsarcopenia group (P

Chronic kidney disease (CKD) patients and renal transplant recipients (RTRs) are characterized by aberrant body composition such as muscle wasting and obesity. It is still unknown which is the most accurate method to estimate body composition in CKD. We investigated the validity of the Hume equation and bioelectrical impedance analysis (BIA) as an estimate of body composition against dual-energy X-ray absorptiometry (DXA) in a cohort of nondialysis dependent (NDD)-CKD and RTRs.

Duplanty, AA, Levitt, DE, Hill, DW, McFarlin, BK, DiMarco, NM, and Vingren, JL. Resistance training is associated with higher bone mineral density among young adult male distance runners independent of physiological factors. J Strength Cond Res 32(6): 1594–1600, 2018—Low bone mineral density (BMD) in male distance runners is common and could be modulated by a host of biomarkers involved in the dynamic balance of bone tissue. In contrast, resistance training can increase BMD; however, the efficacy of resistance training in protecting BMD in distance runners has not been elucidated. The aim of this study was to i...

Lumbar spine TBS, a texture index derived from lumbar spine dual-energy x-ray absorptiometry (DXA) images, enhances fracture prediction. No studies to date have studied a broad range of clinical variables to determine which patients might experience the greatest benefit from the use of TBS.

AbstractSummaryVitamin D deficiency has been reported in patients with gastrointestinal disorders. Little is known on the potentially deleterious effect of cholecystectomy on vitamin D levels and osteoporosis. We found that 25-hydroxyvitamin D levels and bone mineral density were lower in patients with prior cholecystectomy.PurposeThe influence of bile salts on vitamin D absorption is well-known, and increased incidence of vitamin D deficiency has been reported in patients with gastrointestinal disorders. Little is known on the potentially deleterious effect of cholecystectomy on vitamin D levels and osteoporosis. Herein, ...

Abstract OBJECTIVE: In a representative sample of US adults, we investigated the associations of nutrient patterns (NP) with bone mineral density (BMD) and fractures. DESIGN: Cross-sectional. SETTING: US community-based National Health and Nutrition Examination Survey (NHANES). SUBJECTS: Participants with measured data on dietary intake and BMD from 2005 to 2010 were included. Principal components analysis was used to identify NP. BMD was measured using dual-energy X-ray absorptiometry. ANCOVA, adjusted logistic and linear regression models were employed, accounting for the complex survey design and...

In uncemented total hip arthroplasty (THA), low bone mineral density (BMD) is associated with aseptic loosening. BMD is usually assessed via dual-energy X-ray absorptiometry (DXA) or quantitative computed tomography, which takes time and exposes patients to radiation. Due to its low risk profile, intraoperative measurement of the trabecular stability might be a useful alternative to DXA.
