Jun Iwamoto
Among females who require the strategies for preventing osteoporosis, appropriate exercise and sport through all their life are important to increase or maintain bone mass. However, the type of exercise and sport applied to females is different in accordance with the lifecycle. Jumping exercise increases bone mineral content(BMC)in prepubescent children(premenarcheal girls). Bone mineral density(BMD)is higher in adolescent athletes who are engaged in weight-bearing activities. Jumping exercise, muscle strengthening exercise, and weight-bearing plus muscle strengthening exercises increase BMD in young adults and premenopausal women...

PURPOSE OF REVIEW: The scope of this review was to review the newest developments in the context of the existing knowledge on premenopausal bone fragility. Fragility fractures are common in postmenopausal women and men and diagnostic criteria for osteoporosis have been agreed and multiple pharmacological treatments have been developed over the last 25 years. In premenopausal women, fragility fractures and very low bone mass are uncommon and osteoporosis in premenopausal women has therefore attracted much less interest...

To evaluate a possible correlation between bone mineral density (BMD) and age at menarche, the present study used the BMD dataset of the Korea National Health and Nutrition Examination Survey IV-V (KNHANES IV-V). Age at menarche had a small but significant association with BMD of the lumbar spine in premenopausal Korean females, aged 20-50 years. INTRODUCTION: To investigate any correlation between bone mineral density (BMD) and age at menarche in Korean females using data from the fourth and fifth Korea National Health and Nutrition Examination Survey (KNHANES IV-V; 2008-2011)...

We have previously reported that premenopausal women with idiopathic osteoporosis (IOP) have profound microarchitectural deficiencies and heterogeneous bone remodeling. Those with the lowest bone formation rate have higher baseline serum insulin-like growth factor-1 (IGF-1) levels and less robust response to teriparatide. Because IGF-1 stimulates bone formation and is critical for teriparatide action on osteoblasts, these findings suggest a state of IGF-1 resistance in some IOP women. To further investigate the hypothesis that osteoblast and IGF-1-related mechanisms mediate differential responsiveness to teriparatide in IOP, we studied circulating osteoblast progenitor (COP) cells and their IGF-1 receptor (IGF-1R) expression...

BACKGROUND: This case report draws attention to the debated role of prophylactic oophorectomy in women undergoing definitive surgical resection of colon and rectal cancers. It can be challenging to discern the indications and appropriate patient population for this procedure based on the current literature. Potential benefits include treatment and prevention of metastatic disease, preventing development of primary ovarian cancer, and prolonging survival. Negative effects include an increase in operative time and potential morbidity, development of osteoporosis, the risk of cardiac events, and decreasing sexual function...

REVIEW
Adi Cohen
Most premenopausal women with low trauma fracture(s) or low bone mineral density have a secondary cause of osteoporosis or bone loss. Where possible, treatment of the underlying cause should be the focus of management. Premenopausal women with an ongoing cause of bone loss and those who have had, or continue to have, low trauma fractures may require pharmacologic intervention. Clinical trials provide evidence of benefits of bisphosphonates and teriparatide for bone mineral density in several types of premenopausal osteoporosis, but studies are small and do not provide evidence regarding fracture risk reduction...

The present cross-sectional study performed using data from the Korea National Health and Nutrition Examination Survey in 9526 women older than 18 years of age demonstrates that high sodium intake is associated with lower bone mineral density and sodium intake ≥2000 mg/day is a risk factor for osteoporosis in postmenopausal women. INTRODUCTION: Several studies have reported that large amount of dietary sodium intake is highly associated with elevated urinary calcium. However, the direct effect of excessive dietary sodium intake on bone mass, as a risk factor for osteoporosis, is still a controversial issue...

The etiology and underlying mechanisms of pregnancy-associated osteoporosis (PAO) are still unknown, since no systematic analyses exist. Our results indicate that PAO is a heterogeneous, rare but severe disease including a substantial number of fractures with a significant delay from first symptom to diagnose. INTRODUCTION: Pregnancy-associated osteoporosis (PAO) is a rare but severe type of premenopausal osteoporosis. Most common symptom includes acute lower back pain due to vertebral fracture predominantly occurring in the last trimester of pregnancy or immediately postpartum...

PURPOSE: Calcium nephrolithiasis is associated with an increased risk of osteoporosis and fracture. Hypercalciuria has been assumed to be pathogenic for bone loss in kidney stone formers, although this association was shown in small cross-sectional studies. We explored the association of urine calcium with bone mineral density in kidney stone formers. MATERIALS AND METHODS: We retrospectively studied bone mineral density in kidney stone formers. Excluded were subjects with hypercalcemia, chronic bowel disease, primary hyperparathyroidism, distal renal tubular acidosis or endogenous creatinine clearance less than 40 ml per minute...

BACKGROUND: We investigated whether there were gender differences in the effect of obesity on bone mineral density (BMD) based on menopausal status. METHODS: We assessed 5,892 consecutive patients 20 to 91 years old who were referred for dual-energy X-ray absorptiometry (DXA) scans. All subjects underwent a standard BMD scan of the hip (total hip and femoral neck) and lumbar spine (L1 to L4) using a DXA scan and body size assessment. Body mass index was used to categorize the subjects as normal weight, overweight, and obese...

Celiac disease is a chronic inflammatory autoimmune enteropathy based disorder that is triggered by the ingestion of gluten in genetically susceptible individuals. The global prevalence of 1% to 2% represents only the tip of the iceberg. The diagnosis is confirmed by positive specific antibody, anti-transglutaminase or anti-endomysium, specific lesions of the small intestine and a response to strict gluten-free diet. The diagnosis is difficult and often delayed because the clinical variability is very large, ranging from digestive clinical presentation "classic" to "atypical" symptoms, often extra-intestinal, that are sometimes attributed to a concomitant disease or a complication...

BACKGROUND: Breast cancer is the most deadly malignancy in Mexican women. Although treatment has improved, it may significantly affect bone mineral status in those who receive it. The aim of this study was to assess the impact of cancer treatment on bone mineral density (BMD) and bone mineral content (BMC), in patients with breast cancer and explore the interaction of menopausal status and clinical stage with cancer treatment on such changes. METHODS: A quasi-experimental design was applied with measurements before and after a chemotherapy treatment in 40 patients with primary diagnosis of invasive breast cancer...

Aromatase inhibitors (AIs) are the first-line recommended standard of care for postmenopausal estrogen receptor-positive breast cancer. Because they cause a profound suppression of estrogen levels, concerns regarding their potential to increase the risk of fracture were rapidly raised. There is currently a general consensus that a careful baseline evaluation is needed of the risk of fracture in postmenopausal women about to start treatment with AIs but also in all premenopausal women with early disease. Bisphosphonates have been shown in several phase III trials to prevent the bone loss induced by cancer treatment, although no fracture data are available...

REVIEW

Bilateral oophorectomy performed in women before they are menopausal induces surgical primary ovarian insufficiency, an acute and chronic deficiency of the hormones normally produced by the ovaries. Without hormone replacement therapy (HRT) most of these women develop severe symptoms of estrogen (E) deficiency and are at increased risk for osteoporosis, cardiovascular disease, cognitive decline, dementia, and the associated increases in morbidity and mortality. In cases in which a hysterectomy has been performed at the time of bilateral oophorectomy transdermal or transvaginal E2 replacement therapy without cyclic progestin replacement is the optimum hormonal management for these women...

Context: Stress fractures are repetitive use injuries in which recurrent strains lead to material fatigue and microarchitectural discontinuities. They account for up to 20% of athletic injuries, more often in women and in the setting of track-and-field events. In women, menstrual disturbances, low body mass index, low energy intake, and sometimes low bone mass, may be contributing factors. There are no standard protocols for evaluation or management of stress fractures. Evidence Acquisition: Available literature published in English was retrieved using the following terms: stress fractures; fractures; osteoporosis, athletes, premenopausal women, and athletic triad; through PubMed...

BACKGROUND: Anticoagulant therapy is a mainstay of treatment subsequent to major orthopedic surgeries. Evidence linking anticoagulant therapy, osteoporosis, and delayed fracture healing is not conclusive. We have previously reported that rivaroxaban significantly inhibited cell growth and energy metabolism in a human osteoblastic cell line. This study analyzed the response of primary female osteoblast cells to rivaroxaban in combination with various bone-modulating hormones. METHODS: Bone samples were taken from both premenopausal (pre-Ob) and postmenopausal (post-Ob) women...
