Osteoporosis is characterized by bone loss and degradation of bone microstructure leading to fracture particularly in elderly people. Osteoporotic bone degeneration and fracture risk can be assessed by bone mineral density and trabecular bone score from 2D projection dual-energy X-ray absorptiometry images. However, multidetector computed tomography image based quantification of trabecular bone microstructure showed significant improvement in prediction of fracture risk beyond that from bone mineral density and trabecular bone score; however, high radiation exposure limits its use in routine clinical in vivo examinations...

Physical activity has a major impact on bone density and on osteoporosis prevention. Sclerostin is produced by osteocytes and inhibits bone formation. The impact of exercise on sclerostin secretion has not been studied so far. This pilot study aimed to explore circulating sclerostin levels immediately after acute exercise. Healthy young women practicing physical activity less than 120 min per week were enrolled. The exercise was a 45-min, low-speed, treadmill running test. Blood samples were taken at rest before exercise and within 5 min after the end of exercise...

AIM: To investigate the effect of mechanical stress on periostin and semaphorin-3A expression in a murine model of postmenopausal osteoporosis and in osteoblast-like MC3T3-E1 cells. MATERIALS AND METHODS: Female mice were divided into three groups and treated with a sham operation, ovariectomy (OVX) or OVX plus treadmill training (OVX+Run). After 10 weeks, tibias were used for histological analysis. MC3T3-E1 cells were burdened by mechanical stress using a centrifuge or were treated with periostin, and the production of biologically-active semaphorin-3A was examined in vitro...

Background and purpose - Patients with osteoporosis who present with an acute onset of back pain often have multiple fractures on plain radiographs. Differentiation of an acute osteoporotic vertebral fracture (AOVF) from previous fractures is difficult. The aim of this study was to investigate the incidence of concomitant AOVFs and previous OVFs in patients with symptomatic AOVFs, and to identify risk factors for concomitant AOVFs. Patients and methods - This was a prospective epidemiological study based on the Registry of Pathological Osteoporotic Vertebral Fractures (REPAPORA) with 1,005 patients and 2,874 osteoporotic vertebral fractures, which has been running since February 1, 2006...

BACKGROUND: Depression is commonly comorbid with many other somatic diseases and symptoms. Identification of individuals in clusters with comorbid symptoms may reveal new pathophysiological mechanisms and treatment targets. The aim of this research was to combine machine-learning (ML) algorithms with traditional regression techniques by utilising self-reported medical symptoms to identify and describe clusters of individuals with increased rates of depression from a large cross-sectional community based population epidemiological study...

Modifiable lifestyle factors may reduce the risk of developing breast cancer. Obesity is associated particularly with post-menopausal breast cancer. Diet is important, and exercise equivalent to running for up to 8 hours each week reduces the risk of breast cancer, both in its own right and through reducing obesity. Alcohol consumption may be responsible for 5.8% of breast cancers in Australia and it is recommended to reduce this to two standard drinks per day. Drinking alcohol and smoking increases the risk for breast cancer and, therefore, it is important to quit tobacco smoking...

This study examined the effects of different exercise intensities and durations on bone mineral density (BMD) and bone strength in senescence-accelerated mouse prone 6 (SAMP6) and determined the involvement of the Wnt signaling pathway in exercise-induced osteogenesis. Three-month-old male SAMP6 mice were randomly assigned to different speeds of treadmill running exercise representing low, medium and high intensity, with the duration of five and nine weeks, respectively. We showed that medium-intensity exercise had positive effects on skeletal health, including BMD and bone strength, and the efficacy was higher than that of low-intensity exercise...

Inflammatory bowel diseases (IBDs) often present as a complex inflammatory process wherein colon lesions (ulcerative colitis, UC) or widespread ulceration and fissure (Crohn's disease, CD) might be accompanied by ancillary extraintestinal manifestations (EIMs) that could involve almost every organ system, but also by autoimmune disorders ranging from psoriasis and rheumatoid arthritis to connective tissue diseases. Certain EIMs are more common related to the activity of the IBD (joint, skin, ocular and oral manifestations), other EIMs typically run a course independent of the IBD activity (hepatobiliary disorders) and some are non-specific disorders (osteoporosis and amyloidosis)...

Weight-bearing exercise is beneficial to bone health. Myostatin (MSTN) deficiency has a positive effect on bone formation. We wondered if a combination of weight-bearing training and polyclonal antibody for MSTN (MsAb) would augment bone formation to a greater degree than single treatment. In this study, rats were randomly assigned to four groups: Control, weight-bearing training (WT), MsAb, and WT+MsAb. The trained rats ran at 15 m/min bearing with 35% of their body weight, 40 min/day (2 min of running followed by 2 min of rest), 6 days/week, for 8 weeks...

Femoral neck stress fractures in young healthy individuals are rare and occur in those who take part in physical training with repetitive loading and those with osteoporosis. Bone density is related to sex hormone status, which is artificially manipulated during gender reassignment. Conflicting evidence currently exists on the effect of cross sex hormone treatment on bone density, with no literature suggesting a link between hormone treatment in gender reassignment and stress fractures. Our aim is to highlight the potential risk of stress fractures amongst transsexual patients receiving cross sex hormones as part of gender reassignment...

Articles that update the state of knowledge regarding osteoporosis run the risk of quickly becoming obsolete because research and studies on osteoporosis today are arousing great interest among researchers, the pharmaceutical and medical equipment industries, governments and even WHO. All orthopedists know about osteoporosis because of its most deleterious effect: osteoporotic fracture. Osteoporosis without fractures does not arouse suspicion because this is a pathological condition with a nonspecific clinical profile...

OBJECTIVE: The use of a levonorgestrel intrauterine system (LNG-IUS) is useful in preventing pregnancy and for the treatment of menstrual disturbances. A smooth or symptom-free transition to and through menopause is possible when LNG-IUS is combined with estrogen therapy. Unfortunately the majority of physicians are generally unaware of this usefulness combined hormonal therapy in the pre-, peri- and postmenopausal women. DESIGN AND METHOD: Based on long-term clinical experience with LNG-IUS in the form of Femilis®, 104 women where followed from the premenopause through the menopausal transition into the postmenopause...

The increasing importance of preventive measures in the field of orthopedics and trauma surgery becomes apparent because of the demographic changes and the high risk for secondary fractures following osteoporotic fractures. Within the fracture treatment chain, orthopedics and trauma surgery are in the "pole position" to initiate these measures in geriatric patients. In the past orthopedists and trauma surgeons have constantly accused of neglecting secondary fracture prevention in fragility fracture patients...

UNLABELLED: Both men and women who sustain a fracture of the distal forearm run an increased risk of sustaining a subsequent hip fracture. Our study implies that these patients may not necessarily constitute a group in which osteoporosis screening is warranted. INTRODUCTION: People who sustain a distal radius fracture run an increased risk of sustaining a subsequent hip fracture. However, many institutions only screen for osteoporosis at the time of a hip fracture...

Physical inactivity is an important contributor to skeletal muscle weakness, osteoporosis, and weight loss in chronic obstructive pulmonary disease. However, the effects of physical inactivity, in interaction with smoking, on lung, muscle, and bone are poorly understood. To address this issue, male mice were randomly assigned to an active (daily running), moderately inactive (space restriction), or extremely inactive group (space restriction followed by hindlimb suspension to mimic bed rest) during 24 weeks and simultaneously exposed to either cigarette smoke or room air...

While mesenchymal stem cells (MSCs) are rapidly cleared from the body following systemic transplantation, their therapeutic benefits typically persist. In this issue, Liu et al. (2015) reveal that the ability of transplanted MSCs to alleviate osteoporosis in systemic lupus erythematosus is maintained through epigenetic changes conferred by secretory action of the MSCs.

Runs of homozygosity (ROHs), in which both parental alleles are identical, have been proposed to have recessive effects on multiple human complex diseases. Osteoporosis is a common complex disease characterized by low bone mineral density (BMD), which is highly heritable. And recessive loci that contribute to BMD variations have been identified. In this study, we performed a genome-wide ROHs association study using our SNP array data from three GWAS samples including 4,900 subjects from Caucasian and Chinese populations...
