    Is sarcopenia associated with osteoporosis? A cross-sectional study of 262 women with hip fracture. European journal of physical and rehabilitation medicine BACKGROUND:Several lines of evidence support the view that sarcopenia and osteoporosis are strictly connected. However, the capability of the updated sarcopenia definition to capture the concomitant presence of osteoporosis has been scarcely investigated. AIM:The main aim was to assess the association between sarcopenia defined according to the revised criteria from the European Working Group on Sarcopenia in Older People (EWGSOP2) and osteoporosis in women with a hip fracture. A second aim was to investigate the thresholds for low appendicular lean mass (aLM) and handgrip strength to optimize osteoporosis detection. DESIGN:Cross-sectional study. SETTING:Rehabilitation hospital. POPULATION:Women with subacute hip fracture. METHODS:A scan by dual-energy x-ray absorptiometry (DXA) was performed to assess body composition. A Jamar dynamometer was used to measure handgrip strength. Sarcopenia was diagnosed with both handgrip strength < 16kg and aLM < 15kg. Osteoporosis was identified with femoral bone mineral density lower than 2.5 standard deviations below the mean of the young reference population. RESULTS:We studied 262 of 290 women. Osteoporosis was found in 189 of the 262 women (72%; 95% CI from 67% to 78%) whereas sarcopenia in 147 (56%; 95% CI from 50% to 62%). After adjustment for age, time interval between fracture and DXA scan and body fat percentage the odds ratio to have osteoporosis for a sarcopenic woman was 2.30 (95% CI from 1.27 to 4.14; P=0.006). Receiver operating characteristic curve analyses showed that the best cut-off points to discriminate osteoporosis were 20kg for handgrip strength and 12.547kg for aLM. Adopting the optimized thresholds to define sarcopenia, the adjusted odds ratio to have osteoporosis for a sarcopenic woman was 3.68 (95% CI from 1.93 to 7.03; P<0.001). CONCLUSIONS:This preliminary study shows a positive association between sarcopenia defined according to the EWGSOP2 criteria and osteoporosis in 262 women with hip fracture. The association may be bettered by refining the cut-off points for low aLM and handgrip strength. CLINICAL REHABILITATION IMPACT:Sarcopenia seems to be a risk factor for osteoporosis in hip-fracture women. The issue, and the potential role of optimized thresholds should be addressed by robust longitudinal studies. 10.23736/S1973-9087.22.07215-X
    Is central sarcopenia a predictor of prognosis for patients with pathological fracture? The surgeon : journal of the Royal Colleges of Surgeons of Edinburgh and Ireland INTRODUCTION:We aimed to investigate the relationship between central sarcopenia and survival in patients with pathological fracture. METHODS:We reviewed records of patients who were treated for pathological fracture of axial and appendicular skeleton in our clinic between 2011 and 2020. We used the psoas: lumbar vertebral index (PLVI) on axial computer tomographic evaluation to assess for central sarcopenia. A multivariate Cox algorithm was applied to recognize these factors independently associated with one month, six months, one year, and overall survival. RESULTS:A total of 147 patients [61 (41.4%) male and 86 (58.6%) female] were included, with an average age of 62.4 years. During the study, 108 (73.4%) patients died, and 39 (26.6%) were alive. The survival rates at 1 month, 6 months, and 1 year after surgery were 94.6%, 68.7%, and 53.1%, respectively. PLVI values ranged from 0.21 to 1.20 with a mean of 0.536 and a median of 0.520. According to the median value of PLVI, 68 patients with sarcopenia had low PLVI and 79 patients without sarcopenia had high PLVI. For the first month, only the preoperative albumin level was identified as a prognostic factor. Eastern Cooperative Oncology Group Performance Status (ECOG), American Society of Anesthesia (ASA) scores and primary malignancy (rapid grade) were strong predictor of poor survival. The PLVI was independent significant predictor of first month (HR, 0.083 [95% CI, 0.011-0.649], p = 0.018) and overall survival (HR, 0.129 [95% CI, 0.034-0.492], p = 0.003). CONCLUSION:The PLVI was a strong predictor of first year, and overall survival in patients with pathological fracture. 10.1016/j.surge.2022.03.005
