Osteosarcopenia is an increasingly recognized geriatric syndrome with a considerable prevalence which increases morbidity and mortality. Although osteosarcopenia is a result of age-related deterioration in muscle and bone, there are many risk factors that provoking osteosarcopenia. These risk factors should be considered by the clinicians to treat osteosarcopenia. We assessed the link between osteosarcopenia and conventional risk factors of cardiovascular diseases. This study was a cross-sectional study that has been conducted within the framework of Bushehr Elderly Health (BEH) program stage II in which participants aged ≥ 60 years were included. Osteopenia/osteoporosis was defined as a t -score ≤  − 1.0 standard deviation below the mean values of a young healthy adult. We defined sarcopenia as reduced skeletal muscle mass plus low muscle strength and/or low physical performance. Osteosarcopenia was considered as the presence of both osteopenia/osteoporosis and sarcopenia. We estimated the age-standardized prevalence of osteosarcopenia for men and women, separately. Using modified Poisson regression analysis, adjusted prevalence ratio (PR) with 95% CI was used to show the measure of associations in the final model. Among 2353 participants, 1205 (51.2%) were women. Age-standardized prevalence of osteosarcopenia was 33.8 (95% CI 31.0–36.5) in men and 33.9 (30.9–36.8) in women. In both sexes, the inverse association was detected with body mass index and having osteosarcopenia (PR 0.84, 95% CI 0.81–0.88 in men and 0.77, 95% CI 0.74–0.80 in women). In both sexes, high-fat mass was positively associated with osteosarcopenia [PR 1.46 (95% CI 1.11–1.92) in men, and 2.25 (95% CI 1.71–2.95) in women]. Physical activity had a significant inverse association in men (PR = 0.64, 95% CI 0.46, 0.88), but not in women. Diabetes was also showed a direct association with osteosarcopenia in men (PR 1.33, 95% CI 1.04–1.69). No associations were detected between the lipid profiles and osteosarcopenia. Results demonstrated a high prevalence of osteosarcopenia in both sexes suggesting a high disease burden in a rapidly aging country. Lifestyle and socioeconomic factors, as well as chronic diseases, were significantly associated with osteosarcopenia.


骨质疏松症是一种日益被认可的老年综合征,其患病率相当高,增加了发病率和死亡率。虽然骨质疏松症是与年龄相关的肌肉和骨骼恶化的结果,但有许多危险因素引起骨质疏松症。这些危险因素是临床医生治疗骨质疏松症应考虑的因素。我们评估了骨质疏松症与心血管疾病常规危险因素之间的联系。本研究是在 Bushehr 老年健康 (BEH) 项目 II 期框架内进行的一项横断面研究,纳入年龄 ≥ 60 岁的参与者。骨量减少/骨质疏松症定义为低于年轻健康成人平均值的 t-评分 ≤-1.0 标准差。我们将肌肉减少症定义为骨骼肌质量减少加上低肌力和/或低体能。骨质减少被认为是骨量减少/骨质疏松症和肌肉减少症的存在。我们分别估计了男性和女性的年龄标准化骨质减少患病率。使用改良 Poisson 回归分析,使用 95% CI 的调整患病率比 (PR) 显示最终模型中的相关性测量。在 2353 名参与者中,1205 名 (51.2%) 是女性。男性骨减少症的年龄标准化患病率为 33.8 (95% CI 31.0-36.5),女性为 33.9 (30.9-36.8)。在两种性别中,发现与体重指数和骨质减少呈负相关 (男性 PR 0.84,95% CI 0.81-0.88,女性 0.77,95% CI 0.74-0.80)。在两种性别中,高脂质量与骨质减少症呈正相关 [男性 PR 1.46 (95% CI 1.11-1.92),女性 PR 2.25 (95% CI 1.71-2.95)]。体力活动在男性中呈显著负相关 (pr = 0.64,95% CI 0.46,0.88),但在女性中无显著负相关。糖尿病也与男性骨质疏松症直接相关 (PR 1.33,95% CI 1.04-1.69)。未检测到血脂谱与骨质疏松之间的相关性。结果表明,男性和女性的骨质减少症患病率均较高,提示在快速老龄化的国家,疾病负担较高。生活方式和社会经济因素,以及慢性疾病,与骨质疏松症显著相关。

METHODS::Apparent calcium absorption, total bone mineral content and density, and mineral contents of the right femur were studied using a growing rat model. Twenty-four male Wistar rats were fed with diets based on extruded whole grain red (RSD) or white sorghum (WSD), and control diet (CD) up to 60 days. The animals fed with sorghum diets consumed less and gained less weight compared to those fed with CD, but the efficiency of all diets was similar. Calcium intake was lower in animals fed with sorghum diets, related to the lower total intake of these animals. Apparent calcium absorption in animals fed with RSD was lower than in those fed with CD (CD: 72.7%, RSD: 51.0%, WSD: 64.8%). No significant differences in bone mineral density of total body, spin, femur, distal femur, tibia and proximal tibia were observed among the groups. However, Ca and P contents in the right femur of the rats consuming RSD were lower, indicating a certain imbalance in the metabolism of these minerals.

METHODS:OBJECTIVE:Controversy exists about the impact of bone mineral density (BMD) and fracture risk in newly diagnosed patients with breast cancer (BC). It is presumed that there are differences in BMD between women with BC and healthy controls. BMD is therefore considered as a potential marker to predict BC risk. This study was conducted to investigate the association of BMD, trabecular bone score (TBS) and fracture risk in younger postmenopausal women with hormone responsive BC. METHODS:Overall, 343 women were examined. Women with BC were matched to a control group of the general population. Forty-nine women and fifty-nine controls were included in the final analysis. All subjects underwent dual energy x-ray absorptiometry (DXA) of the lumbar spine, femoral neck, and the total hip to evaluate bone mineral density. The 10-year fracture risk for a major osteoporotic fracture was assessed using the FRAX-score and the TBS-adjusted FRAX-Score, respectively. RESULTS:Lumbar and femoral neck BMD were similar in BC patients and controls. No difference was found for TBS of the spine (1.38 ± 0.1 vs.1.36 ± 0.09) in the BC and the control group, respectively (p = 0.19). The 10- year probability for a major osteoporotic fracture (MoF) or femoral neck (FN) fracture was 6.1 (± 2.6%) and 0.9 (± 1.2%) in the BC group vs. 6.7 (± 3.5%) (p = 0.33) and 0.9 (± 1.1%) (p = 0.73) in the control group. CONCLUSION:Postmenopausal women younger than 60 years with breast cancer do not show any differences in baseline BMD, TBS, or TBS adjusted FRAX in comparison to controls.

METHODS::The goals of this study are to evaluate the ability of the multicomponent collagen-elastin-like polypeptide (ELP)-Bioglass scaffolds to support osteogenesis of rat mesenchymal stem cells (rMSCs), demonstrate in vivo biocompatibility by subcutaneous implantation in Sprague-Dawley rats, monitor degradation noninvasively, and finally assess the scaffold's ability in healing critical-sized cranial bone defects. The collagen-ELP-Bioglass scaffold supports the in vitro osteogenic differentiation of rMSCs over a 3 week culture period. The cellular (rMSC-containing) or acellular scaffolds implanted in the subcutaneous pockets of rats do not cause any local or systemic toxic effects or tumors. The real-time monitoring of the fluorescently labeled scaffolds by IVIS reveals that the scaffolds remain at the site of implantation for up to three weeks, during which they degrade gradually. Micro-CT analysis shows that the bilateral cranial critical-sized defects created in rats lead to greater bone regeneration when filled with cellular scaffolds. Bone mineral density and bone microarchitectural parameters are comparable among different scaffold groups, but the histological analysis reveals increased formation of high-quality mature bone in the cellular group, while the acellular group has immature bone and organized connective tissue. These results suggest that the rMSC-seeded collagen-ELP-Bioglass composite scaffolds can aid in better bone healing process.
