Tai Chi Chuan

Osteoporosis is a disease characterized by fragile bones and high susceptibility to low trauma fractures. Tai Chi, an ancient Chinese mind-body exercise that is reported to enhance muscle function, balance and flexibility, and to reduce pain, depression and anxiety, may safely and effectively be used to prevent or treat osteoporosis. The aim of this review is to evaluate the evidence for Tai Chi as an intervention to reduce rate of bone loss in postmenopausal women. A literature search on randomized controlled trials (RCTs), prospective cohort studies, and cross-sectional studies that included Tai Chi as an intervention, and had at least 1 outcome related to measurement of bone metabolism were identified in PubMed/Medline. Twenty-one controlled studies were identified in the database, which suggested Tai Chi slowed down the loss of bone mineral density in most postmenopausal women, improved balance and strength, relieves pain from arthritis, and improved mental strength so they can cope better with chronic diseases. Regular Tai Chi Chuan exercise is beneficial for retarding bone loss in the weight-bearing bones of postmenopausal women.

The Mean

Breast cancer and osteoporosis are both diseases of aging. The "one in eight" lifetime risks of breast cancer occur primarily in the sixth, seventh, eighth, and ninth decades of life. One-third of postmenopausal women will experience an osteoporotic fracture. It is the coalescence of osteoporosis, breast cancer, and breast cancer treatments that, in some cases, increases the risks of osteoporotic fracture. That makes it imperative to assess risk factors, screen, and prevent or treat osteoporosis in postmenopausal women with breast cancer. Osteoporosis is primarily a genetic disease with a few modifiable risk factors. These risk factors include greater than two to three alcoholic drinks per day, current smoking, and decreased physical activity. The standard screening tool for osteoporosis is dual-energy x-ray absorptiometry (DXA) that gives a readout of T-scores of the lumbar spine, total hip, and femoral neck. The T-score is the number of standard deviations (SD) above or below the mean bone mineral density (BMD) of an average young adult of the same sex. For every SD below the mean BMD, the fracture risks double. Osteoporosis prevention and treatment do not differ in women with or without breast cancer. The difference is in breast cancer treatments, such as aromatase inhibitors (AI), which cause two to three-fold higher bone loss than average postmenopausal bone loss. Two classes of drugs for osteoporosis are oral and intravenous (iv) bisphosphonates and the receptor activator of nuclear factor kappa B ligand (RANKL) ligand inhibitor, subcutaneous (sc) denosumab. All three prevent bone loss and reduce the likelihood of fragility fractures. The treatment choice depends upon patient and provider preferences, specific contraindications (e.g., renal insufficiency), compliance, and costs. Despite guidelines and algorithms for AI-induced bone loss, the screening and treatment of osteoporosis remain suboptimal in postmenopausal women with breast cancer.

AbstractOsteocytes act as mechanosensors in bone; however, the underlying mechanism remains poorly understood. Here we report that deleting Kindlin-2 in osteocytes causes severe osteopenia and mechanical property defects in weight-bearing long bones, but not in non-weight-bearing calvariae. Kindlin-2 loss in osteocytes impairs skeletal responses to mechanical stimulation in long bones. Control and cKO mice display similar bone loss induced by unloading. However, unlike control mice, cKO mice fail to restore lost bone after reloading. Osteocyte Kindlin-2 deletion impairs focal adhesion (FA) formation, cytoskeleton organization and cell orientation in vitro and in bone. Fluid shear stress dose-dependently increases Kindlin-2 expression and decreases that of Sclerostin by downregulating Smad2/3 in osteocytes; this latter response is abolished by Kindlin-2 ablation. Kindlin-2-deficient osteocytes express abundant Sclerostin, contributing to bone loss in cKO mice. Collectively, we demonstrate an indispensable novel role of Kindlin-2 in maintaining skeletal responses to mechanical stimulation by inhibiting Sclerostin expression during osteocyte mechanotransduction.

The aim of this study was to determine the effects of ß-hydroxy-ß-methylbutyrate (HMB) supplementation during pregnancy on postpartum bone tissue quality by assessing changes in trabecular and compact bone as well as in hyaline and epiphyseal cartilage. The experiment was carried out on adult 6-month-old female spiny mice (Acomys cahirinus) divided into three groups: pregnant control (PregCont), pregnant HMB-treated (supplemented with 0.02 g/kg b.w of HMB during the second trimester of pregnancy, PregHMB), and non-pregnant females (NonPreg). Cross-sectional area and cortical index of the femoral mid-shaft, stiffness, and Young modulus were significantly greater in the PregHMB group. Whole-bone mineral density was similar in all groups, and HMB supplementation increased trabecular number. Growth plate cartilage was the thinnest, while the articular cartilage was the thickest in the PregHMB group. HMB supplementation increased the content of proteoglycans in the articular cartilage and the percentage of immature collagen content in metaphyseal trabeculae and compact bone. In summary, dietary HMB supplementation during the second trimester of pregnancy intensifies bone metabolic processes and prevents bone loss during pregnancy.

Objectives:Previous studies suggest that high systemic bone mineral density (BMD) is associated with incident knee osteoarthritis (OA) defined by osteophytes but not with joint space narrowing (JSN), and are inconsistent regarding BMD and progression of existing OA. The association of BMD with incident and progressive tibiofemoral OA was tested in a large prospective study of men and women aged 50–79 years with or at risk for knee OA.Methods:Baseline and 30-month weight-bearing posteroanterior and lateral knee radiographs were scored for Kellgren-Lawrence (K-L) grade, JSN and osteophytes. Incident OA was defined as the development of K-L grade ⩾2 at follow-up. All knees were classified for increases in grade of JSN and osteophytes from baseline. The association of gender-specific quartiles of baseline BMD with risk of incident and progressive OA was analysed using logistic regression, adjusting for covariates.Results:The mean (SD) age of 1754 subjects was 63.2 (7.8) years and body mass index was 29.9 (5.4) kg/m2. In knees without baseline OA, higher femoral neck and whole body BMD were associated with an increased risk of incident OA and increases in grade of JSN and osteophytes (p<0.01 for trends); adjusted odds were 2.3–2.9-fold greater in the highest compared with the lowest BMD quartiles. In knees with existing OA, progression was not significantly related to BMD.Conclusions:In knees without OA, higher systemic BMD was associated with a greater risk of the onset of JSN and K-L grade ⩾2. The role of systemic BMD in early knee OA pathogenesis warrants further investigation.

The aim of the present study was to identify the association of dietary patterns with osteoporosis in Korean postmenopausal women from the Korean Health and Nutrition Examination Survey 2008–10. The present cross-sectional analysis included 3735 postmenopausal women who completed a health interview, nutrition survey and a health examination including bone mineral density (BMD) measurements. The general characteristics and dietary intakes of the participants were obtained using a standardised questionnaire and a 24 h recall method, respectively. The BMD of the femoral neck and lumbar spine was measured using dual-energy X-ray absorptiometry; osteoporosis was defined based on the WHO T-score criteria. Overall, we identified four dietary patterns using factor analysis as follows: ‘meat, alcohol and sugar’, ‘vegetables and soya sauce’, ‘white rice, kimchi and seaweed’ and ‘dairy and fruit’, which accounted for 30·9 % of the total variance in food intake (11·3, 7·7, 6·0 and 5·9 %, respectively). The subjects in the highest quintile of the ‘dairy and fruit’ pattern showed a decreased risk of osteoporosis of the lumbar spine (53 %) compared with those in the lowest quintile, after adjusting for covariates (OR 0·47, 95 % CI 0·35, 0·65, P for trend < 0·0001). In contrast, the ‘white rice, kimchi and seaweed’ dietary pattern was negatively associated with bone health (OR 1·40, 95 % CI 1·03, 1·90, P for trend = 0·0479). The present results suggest that an increased intake of dairy foods and fruits in the traditional Korean diet, based on white rice and vegetables, may decrease the risk of osteoporosis in Korean postmenopausal women.
