Bone mineral density (BMD) changes during the life span, increasing rapidly during adolescence, plateauing in the third decade of life, and subsequently entering a phase of age-related decline. In women, menopause leads to accelerated bone loss and an increase in fracture risk. Between peak bone mass attainment and menopause, BMD is generally stable and the risk of fracture is typically low. This time period is marked by life events such as pregnancy and lactation, which transiently decrease BMD, yet their long-term effects on fracture risk are less certain. BMD may also be altered by exposure to medications that affect bone metabolism (e.g., contraceptives, glucocorticoids, antidiabetic medications, antiepileptic drugs). Although oral contraceptives are often believed to be neutral with regard to bone health, depot medroxyprogesterone acetate (DMPA) and gonadotropin-releasing hormone (GnRH) agonists have been associated with decreases in BMD. Development of newer medical therapies, principally GnRH antagonists (e.g., ASP1707, elagolix, linzagolix, relugolix), for treatment of endometriosis-associated pelvic pain and heavy menstrual bleeding due to uterine fibroids has renewed interest in the short- and long-term impacts of changes in BMD experienced by premenopausal women. It is important to understand how these drugs influence BMD and put the findings into context with regard to measurement variability and naturally occurring factors that influence bone health. This review summarizes what is known about the effects on bone health pregnancy, lactation, and use of DMPA, GnRH agonists, and GnRH antagonists in premenopausal women and potential consequences later in life.

The article presents information on developments in atypical femoral fractures (AFF) and discusses evidence for diagnosis, prevention and management. Topics discussed include the characterization of AFFs, the definition of AFF by the American Society for Bone and Mineral Research, and the association of atypical fractures with total joint arthroplasty.

In postmenopausal women, osteoporotic fractures are more common than stroke, myocardial infarction, and breast cancer combined, and fractures can be costly and result in disability or death. Because there are no signs or symptoms of osteoporosis other than fracture, risk assessment is necessary to identify those at higher risk for clinical events. For women, a clinical fracture risk assessment (FRAX) is appropriate at menopause. Bone mineral density (BMD) measurement is recommended for women at age 65, and earlier for those who have risk factors. Adequate calcium, vitamin D, and weight-bearing exercise are important for bone health at all ages, and those at high risk for fracture based on BMD or FRAX should be offered medical therapy to reduce fracture risk after an appropriate medical evaluation. Bisphosphonates can accumulate in bone, so after a period of treatment, lower risk patients may be offered a period off drug therapy. However, the effects of denosumab are not sustained when treatment is discontinued, so there is no “drug holiday” with denosumab. Anabolic therapy can be offered to those with higher risk for fracture. Although rare safety concerns regarding atypical femoral fracture and osteonecrosis of the jaw have received prominent attention, for patients who are appropriately treated according to National Osteoporosis Foundation guidelines, the benefit of hip fracture risk reduction far outweighs the risk of these uncommon side effects. Accurate information for patients and shared decision-making are important for acceptance and persistent with appropriate treatment. [ABSTRACT FROM AUTHOR]

GLOW is an observational, longitudinal, practice-based cohort study of osteoporosis in 60,393 women aged >55 years in 10 countries on three continents. In this Review, we present insights from the first 3 years of the study. Despite cost analyses being frequently based on spine and hip fractures, we found that nonvertebral, nonhip fractures were around five times more common and doubled the use of health-care resources compared with hip and spine fractures combined. Fractures not at the four so-called major sites in FRAX® (upper arm, forearm, hip and clinical vertebral fractures) account for >40% of all fractures. The risk of fracture is increased by various comorbidities, such as Parkinson disease, multiple sclerosis and lung and heart disease. Obesity, although thought to be protective against all fractures, substantially increased the risk of fractures in the ankle or lower leg. Simple assessment by age plus fracture history has good predictive value for all fractures, but risk profiles differ for first and subsequent fractures. Fractures diminish quality of life as much or more than diabetes mellitus, arthritis and lung disease, yet women substantially underestimate their own fracture risk. Treatment rates in patients at high risk of fracture are below those recommended but might be too frequent in women at low risk. Comorbidities and the limits of current therapeutic regimens jeopardize the efficacy of drugs; new regimens should be explored for severe cases. [ABSTRACT FROM AUTHOR]

Abstract: There are numerous causes of secondary osteoporosis including endocrine disorders, nutritional deficiencies, and other miscellaneous conditions and medications. It is essential to identify and address these factors to appropriately manage patients with osteoporosis. Failure to do so may result in further bone loss despite pharmacologic intervention for osteoporosis. The following diagnostic studies should be considered initially: complete blood count, complete metabolic panel, 25-hydroxyvitamin D level, testosterone level in men, and 24-hour urinary calcium, sodium, and creatinine. Further testing may be performed in selected patients depending on the clinical picture and results of the initial workup. [ABSTRACT FROM AUTHOR]

Abstract: Objective: To investigate the prevalence and incidence of clinical fractures in obese, postmenopausal women enrolled in the Global Longitudinal study of Osteoporosis in Women (GLOW). Methods: This was a multinational, prospective, observational, population-based study carried out by 723 physician practices at 17 sites in 10 countries. A total of 60,393 women aged ≥55 years were included. Data were collected using self-administered questionnaires that covered domains that included patient characteristics, fracture history, risk factors for fracture, and anti-osteoporosis medications. Results: Body mass index (BMI) and fracture history were available at baseline and at 1 and 2 years in 44,534 women, 23.4% of whom were obese (BMI ≥30 kg/m2). Fracture prevalence in obese women at baseline was 222 per 1000 and incidence at 2 years was 61.7 per 1000, similar to rates in nonobese women (227 and 66.0 per 1000, respectively). Fractures in obese women accounted for 23% and 22% of all previous and incident fractures, respectively. The risk of incident ankle and upper leg fractures was significantly higher in obese than in nonobese women, while the risk of wrist fracture was significantly lower. Obese women with fracture were more likely to have experienced early menopause and to report 2 or more falls in the past year. Self-reported asthma, emphysema, and type 1 diabetes were all significantly more common in obese than nonobese women with incident fracture. At 2 years, 27% of obese women with incident fracture were receiving bone protective therapy, compared with 41% of nonobese and 57% of underweight women. Conclusions: Our results demonstrate that obesity is not protective against fracture in postmenopausal women and is associated with increased risk of ankle and upper leg fractures.

Osteoporosis is a serious health concern affecting millions of Americans, with many patients going undiagnosed and untreated. Fractures due to osteoporosis and fracture-related complications are the most clinically relevant and costly consequences of this disorder. The Fracture Risk Assessment Tool (FRAX®), released by the World Health Organization (WHO) in February 2008, is a major achievement in helping determine which patients may be candidates for pharmacological therapy for osteoporosis. This Web-based algorithm, which has been incorporated into some dual x-ray absorptiometry (DXA) reporting software, calculates the 10-year probability of major osteoporotic fracture (clinical vertebral, hip, forearm, or humerus) and the 10-year probability of hip fracture in men and women based on easily obtained clinical risk factors and bone mineral density (BMD) of the femoral neck (optional). The National Osteoporosis Foundation updated its U.S. guidelines in February 2008 to incorporate FRAX and recommends that all postmenopausal women and men aged ≥50 years with a hip or vertebral fracture, a T-score ≤−2.5 at the femoral neck or spine (excluding secondary causes), or low bone mass (T-score between −1.0 and −2.5) and a 10-year probability of hip fracture ≥3% or of major osteoporosis-related fracture ≥20% (based on FRAX) should be considered candidates for drug therapy. Despite its demonstrated clinical utility, FRAX has limitations and should not be used in all situations. Acceptance and clinical use of FRAX may help identify men and women at increased risk for osteoporotic fracture, but implementing the tool into clinical practice may be a challenge for busy physicians.

These guidelines, which are developed by the World Health Organization Fracture Risk Assessment Tool and the National Osteoporosis Foundation (NOF), are helpful clinical tools in the management of osteoporosis.

The first bisphosphonate (etidronate) was approved by the FDA in 1977; alendronate was approved in 1995 for the prevention and treatment of osteoporosis. Bisphosphonates have emerged as the agents of choice for the treatment of osteoporosis and have proved useful in the treatment of skeletal complications of malignancy (hypercalcemia, bone metastases) and have been used long-term in millions of patients. Osteonecrosis of the jaw (ONJ) is a newly described condition (2003) defined as exposed bone in the maxillofacial area, not associated with radiation or any other known cause and not healing for 8 weeks. Most cases have followed dental extraction, another invasive dental procedure, or poorly fitting dentures. Although most cases are painful and it can be progressive, approximately one-third of cases are painless and some do resolve. Although ONJ occurs exclusively or almost exclusively in patients receiving bisphosphonate therapy, a causal association has not been shown, and the mechanism is not clear. In patients receiving high-dose IV bisphosphonates for malignant diseases, ONJ may occur in 5 to 10% over 3 years. It does occur in patients receiving oral or IV bisphosphonates for osteoporosis, but is rare in that setting; about 1 case per 100,000. Treatment is conservative (antimicrobial mouthwash, antibiotics for secondary infection, limited debridement). Preventive strategies should include good dental hygiene for all patients and completion of elective invasive dental procedures before initiating high-dose IV bisphosphonate therapy for cancer. Patients with osteoporosis receiving lower-dose bisphosphonate therapy do not require special precautions, but should be informed of the low risk of this complication. [ABSTRACT FROM AUTHOR]

Measurement of bone mineral density (BMD) with central dual-energy X-ray absorptiometry (DXA) is the current “gold standard” for diagnosing osteoporosis and for monitoring patients. Errors in demographic information, improper patient positioning, incorrect scan analysis, and mistakes in interpretation can all lead to a wrong clinical decision or action. This paper reviews the fundamentals of positioning, scan analysis, and interpretation for central DXA and highlights some of the common pitfalls that may lead to erroneous results.

Placebo controls are essential to assess anti-fracture efficacy of new osteoporosis therapies, but inclusion of a placebo arm in a subsequent clinical trial may be limited by practical or ethical considerations; in these cases, use of an historical control may be appropriate. A recent active-controlled study of risedronate 35 mg once a week demonstrated that this regimen produces increases in bone mineral density (BMD) that are comparable to those seen with the risedronate 5 mg daily dose, which has proven anti-fracture efficacy. To assess the anti-fracture efficacy of this new regimen, we have analyzed the fracture data collected in an active controlled study of risedronate dosing regimens (the Once-a-Week study) using matched historical control data from previous placebo-controlled trials. Women in the Once-a-Week study were matched for age, years since menopause, BMD, and prevalent vertebral fracture status, with placebo patients in the Vertebral Efficacy of Risedronate Therapy (VERT) trials forming an historical placebo group. We also constructed an historical active treatment group from the 5 mg daily arm of the VERT trials for comparison with the 5 mg daily and 35 mg once weekly treatment groups in the Once-a-Week study. Data were obtained from the risedronate 5 mg daily group (n=480) and 35 mg once-a-week group (n=485) in the Once-a-Week study and historical control groups representing daily placebo patients (n=114, matched from 993) and risedronate 5 mg daily patients (n=120; matched from 990) in the VERT studies. Patients received calcium supplementation (1000 mg daily); vitamin D was given if baseline serum 25-hydroxyvitamin D levels were low. Over 1 year, new vertebral fracture risk in the 35 mg once-a-week group was reduced by 77% relative to the historical placebo group (1.2% versus 5.0%; RR 0.23; 95% CI, 0.54 to 0.91, P=0.018), similar to the 1-year risk reduction observed in the VERT trials of risedronate 5 mg daily (61–65%). The incidence of new vertebral fractures in the three active treatment groups was similar: 1.7% in the historical risedronate 5 mg group, 1.5% in the risedronate 5 mg daily group from the Once-a-Week study, and 1.2% in the 35 mg once-a-week group. Risedronate 35 mg once a week appears as effective as the 5 mg daily dose in reducing the risk of new vertebral fractures in the first year of treatment. The use of appropriate historical control data provides an approach to the assessment of fracture effects in osteoporosis trials for which placebo-controlled data are not available.

We reviewed the epidemiology, diagnosis, and treatment of vertebral fractures due to osteoporosis in the elderly. Vertebral fractures are underdiagnosed despite their high prevalence in both men and women. Clinical consequences of vertebral fractures include increased risk of future vertebral and hip fracture, acute and chronic back pain, decreased quality of life, and increased mortality. Patients with vertebral fractures have functional impairment and increased mortality similar to those with hip fractures. Asymptomatic fractures identified on radiograph also affect quality of life and mortality. A vertebral fracture is a clinical marker for a subsequent fracture and should trigger assessment and diagnosis of osteoporosis. The care of patients with vertebral fractures includes pain management, rehabilitation, and prevention of further fractures. There is evidence from randomized controlled trials that pharmacologic therapy can reduce the risk of future fractures by 40% to 50%. Vertebroplasty may be effective in the control of pain and in obtaining stability of the spine. [Copyright &y& Elsevier]

Summary A number of agents have been shown to reduce the risk of fractures in patients with postmenopausal osteoporosis. However, the additional benefits of combination therapy as opposed to monotherapy are uncertain. We performed a MEDLINE search and reviewed the published randomized trials of agents used in combination. Combination therapy results in greater gains in bone mineral density than monotherapy and possibly greater effects on bone turnover. However, none of these studies are large enough or of sufficient duration to determine whether a greater reduction in fracture is achieved. Combination therapy has important cost implications and is likely to be associated with an increased prevalence of adverse events, reduced tolerability and a reduction in adherence. Furthermore, over-suppression of bone turnover as a result of combination antiresorptive therapy might have adverse effects on bone strength, particularly with long-term treatment. Thus, the use of combination therapy for treatment of osteoporosis cannot be recommended on the basis of currently available evidence. [ABSTRACT FROM AUTHOR]

Examines the long-term effect of intermittent cyclic etidronate treatment on postmenopausal osteoprosis. Study design; Treatment regimens; Bone mass measurements; Radiographic assessment; Biochemical and statistical analyses; Effect on spinal and hip bone density with three years of therapy; Effect on vertebral fracture rates in patients.

Purpose: To determine the efficacy and safety of cyclical etidronate for up to 7 years in the treatment of postmenopausal osteoporosis and to examine the effects of discontinuing treatment after 2 or 5 years of therapy.Patients and Methods: Patients were randomized at entry into the original study in 1986 to blinded treatment for 2 years with either a calcium (placebo) or an intermittent cyclical etidronate regimen, which most patients continued for a third year. Following this phase of the study, patients were enrolled into an open-label, follow-up study (years 4 and 5), during which all patients received cyclical etidronate treatment. In the present double-blind study (years 6 and 7), patients were rerandomized to receive intermittent cyclical therapy with either etidronate or placebo; all patients received calcium. The treatment regimen consisted of 400 mg/day etidronate or placebo for 14 days, followed by 76 days of elemental calcium (500 mg/day); this cycle was repeated approximately 4 times in each year. Of the 193 patients who continued in years 6 and 7 of the study, 93 were randomized to receive cyclical etidronate and 100 were randomized to receive calcium only. For purposes of efficacy analyses, patients were categorized by their total years of cumulative etidronate treatment (7, 5, 4, or 2 years). There were 51, 46, 42, and 54 patients in the 7-, 5-, 4-, and 2-year groups, respectively. Annual assessments included lumbar spine bone mineral density (BMD), as measured by densitometry, and vertebral radiographs.Results: The groups receiving cyclical etidronate during this 2-year study period (7- and 4-year groups) had statistically significant mean percent increases in spinal BMD of 1.8% and 2.2%, respectively (P < 0.05) at the week 104 observation time. The 5- and 2-year groups, which did not receive etidronate during this period, had mean values of 1.4% and 0.2%, respectively (not significant) at week 104. In the 7-, 5-, 4-, and 2-year groups, the increases in spinal BMD at the end of 7 years were 7.6%, 8.6%, 8.1%, and 3.9%, respectively; these values were statistically significant for all groups compared with original baseline (year 0) (P < 0.05). BMD of the femur and wrist was maintained throughout the 7-year period. The incidence and rate of vertebral fractures were lowest in patients with the longest exposure to etidronate. Etidronate was well tolerated during the study, with low incidences of gastrointestinal side effects and nonvertebral fractures.Conclusions: Long-term cyclical etidronate is a safe, effective, and well-tolerated treatment for postmenopausal osteoporosis. Bone mass is maintained for at least 2 years after treatment with etidronate is stopped; however, further gains in spinal bone mass are seen in patients who continue therapy. [ABSTRACT FROM AUTHOR]

Etidronate is a non-nitrogen-containing bisphosphonate. Because it binds with calcium and inhibits crystal formation and dissolution, it was considered by Procter & Gamble as an additive to toothpaste (to prevent build-up of tartar) and detergent (to bind calcium and increase sudsing in "hard" water). The first clinical use (1968) was for fibrodysplasia ossificans progressiva. The first approved clinical use (1977) was for treatment of Paget's disease of bone. Other approved indications are hypercalcemia of malignancy and heterotopic ossification, with a host of off-label uses (including fibrous dysplasia, periodontal disease, multiple myeloma, neuropathic arthropathy, pulmonary microlithiasis, diabetic retinopathy, bone metastases, melorheostosis, urinary stone disease, periodontal disease, etc.). Unique among bisphosphonates, etidronate (oral therapy) results in hyperphosphatemia, increased tubular reabsorption of phosphorus and increased levels of 1,25-dihydroxyvitamin D. The dose that reduces bone resorption is close to the dose that impairs mineralization; prolonged high-dose use can result in osteomalacia and bone fractures. Intermittent cyclic etidronate for osteoporosis resulted in favorable changes in bone density and histomorphometry (no mineralization defect) as well as a decrease in vertebral fracture rates in postmenopausal women with osteoporosis. Later studies showed similar effects in men with osteoporosis and patients with glucocorticoid-induced osteoporosis. Although its use for osteoporosis has given way to newer bisphosphonates and other agents, because of its unique properties, it remains the bisphosphonate of choice for treatment of heterotopic ossification. • Etidronate, a non-nitrogen-containing bisphosphonate, was the first in this class to be used clinically • In the 1970s, 80s and early 90s, etidronate was widely use for treatment of Paget's disease and osteoporosis • Clinical use has markedly diminished, but etidronate is still used for treatment of heterotopic ossification [ABSTRACT FROM AUTHOR]

The authors reflect on shared decision making in clinical practice in connection with osteoporosis and fracture risk evaluation and management practices in the U.S. as of 2017. American public health problems and mortality risk are examined, along with the medical care costs that are associated with osteoporosis-related fractures. Spinal and pelvic fractures are assessed, as well as bone mineral density measurements. The relationships between vitamin D, calcium, and bone health are mentioned.

Although calcium and vitamin D supplementation may affect chronic disease in older women, evidence of long-term effects on health outcomes is limited. This post hoc analysis examines long-term postintervention outcomes with more than 20 years of follow-up of a 7-year randomized intervention trial of calcium and vitamin D. Visual Abstract. Long-Term Effect of Randomization to Calcium and Vitamin D Supplementation on Health in Older Women: Although calcium and vitamin D supplementation may affect chronic disease in older women, evidence of long-term effects on health outcomes is limited. This post hoc analysis examines long-term postintervention outcomes with more than 20 years of follow-up of a 7-year randomized intervention trial of calcium and vitamin D. Background: Although calcium and vitamin D (CaD) supplementation may affect chronic disease in older women, evidence of long-term effects on health outcomes is limited. Objective: To evaluate long-term health outcomes among postmenopausal women in the Women's Health Initiative CaD trial. Design: Post hoc analysis of long-term postintervention follow-up of the 7-year randomized intervention trial of CaD. (ClinicalTrials.gov: NCT00000611) Setting: A multicenter (n = 40) trial across the United States. Participants: 36 282 postmenopausal women with no history of breast or colorectal cancer. Intervention: Random 1:1 assignment to 1000 mg of calcium carbonate (400 mg of elemental calcium) with 400 IU of vitamin D 3 daily or placebo. Measurements: Incidence of colorectal, invasive breast, and total cancer; disease-specific and all-cause mortality; total cardiovascular disease (CVD); and hip fracture by randomization assignment (through December 2020). Analyses were stratified on personal supplement use. Results: For women randomly assigned to CaD versus placebo, a 7% reduction in cancer mortality was observed after a median cumulative follow-up of 22.3 years (1817 vs. 1943 deaths; hazard ratio [HR], 0.93 [95% CI, 0.87 to 0.99]), along with a 6% increase in CVD mortality (2621 vs. 2420 deaths; HR, 1.06 [CI, 1.01 to 1.12]). There was no overall effect on other measures, including all-cause mortality (7834 vs. 7748 deaths; HR, 1.00 [CI, 0.97 to 1.03]). Estimates for cancer incidence varied widely when stratified by whether participants reported supplement use before randomization, whereas estimates on mortality did not vary, except for CVD mortality. Limitation: Hip fracture and CVD outcomes were available on only a subset of participants, and effects of calcium versus vitamin D versus joint supplementation could not be disentangled. Conclusion: Calcium and vitamin D supplements seemed to reduce cancer mortality and increase CVD mortality after more than 20 years of follow-up among postmenopausal women, with no effect on all-cause mortality.

A letter to the editor is presented in response to the article "Narrative (Corrected) Review: Biphosphonates and Osteonecrosis of the Jaws," by S. B. Woo, J. W. Hellstein and J. R. Kalmar .

The article discusses the diagnosis and evaluation of patients with Osteoporosis. Osteoporosis is a silent condition characterized by reduced bone mass and abnormal bone architecture, with an associated increase in the risk of fractures. Biochemical markers of bone turnover may be useful to decide if treatment is needed and to determine the effectiveness of treatment. Osteoporosis in adults is commonly caused by estrogen deficiency and aging. However, bone loss may be secondary to a variety of diseases and conditions. Bone biopsy should be considered in patients who have unusual features of osteoporosis, men and young women who have osteoporosis, patients who have very low bone mass, patients who have fragility fractures but normal bone mass and patients failing conventional therapy.

Focuses on advances in endocrinology. Improved understanding of the management of some common endocrine diseases; Treatment of osteoporosis; Treatments for achieving increases in bone density and decreases in the incidence of vertebral fracture; Glucocorticoid therapy.

Osteoporosis is a condition that affects approximately 44 million Americans and is characterized by reduced bone mass and an increased risk of fractures. Of the 1.5 million osteoporotic fractures in the United States each year, vertebral fractures are the most common, while hip fractures are the most serious, with 10-20% of those victims dying within one year. The articles focus on the available methods of diagnosing osteoporosis, the existing treatment options, the importance of self-management and low bone mineral density, and the prevention of glucocorticoid-induced osteoporosis.

Background: Osteoporosis is a widespread but largely preventable disease. Improved adherence to screening and treatment recommendations is needed to reduce fracture and mortality rates. Additionally, clinicians face increasing demands to demonstrate proficient quality patient care aligning with evidence-based standards. Methods: A three-stage, clinician-focused performance improvement (PI) continuing medical education (CME) initiative was developed to enhance clinician awareness and execution of evidence-based standards of osteoporosis care. Clinician performance was evaluated through a retrospective chart analysis of patients at risk or with a diagnosis of osteoporosis. Results: Seventy-five participants reported their patient practices on a total of 1875 patients before and 1875 patients after completing a PI initiative. Significant gains were made in the use of Fracture Risk Assessment Tool (FRAX) (stage A, 26%, n=1769 vs. stage C, 51%, n=1762; p<0.001), assessment of fall risk (stage A, 46%, n=1276 vs. stage C, 89%, n=1190; p<0.001), calcium levels (stage A, 62%, n=1451 vs. stage C, 89%, n=1443; p<0.001), vitamin D levels (stage A, 79%, n=1438 vs. stage C, 93%, n=1439; p<0.001), and medication adherence (stage A, 88%, n=1136 vs. stage C, 96%, n=1106; p<0.001). Conclusions: Gains in patient screening, treatment, and adherence were associated with an initiative promoting self-evaluation and goal setting. Clinicians must assess their performance to improve patient care and maintain certification. PI CME is a valid, useful educational tool for accomplishing these standards. [ABSTRACT FROM AUTHOR]

Abstract: Bisphosphonates are effective in reducing bone turnover, increasing BMD and reducing fracture risk in postmenopausal women with osteoporosis. The licensed bisphosphonates exhibit some differences in potency and speed of onset and offset of action. These differences mean that different agents may be more advantageous in different situations. Uncertainties still exist around the optimum duration of treatment and treatment holidays, how best to use bisphosphonates with anabolic treatments, and the benefits of treatment in patients who do not have a BMD T-score below −2.5. This article is part of a Special Issue entitled Bisphosphonates. [Copyright &y& Elsevier]

This paper describes the development of a biosensor based on label-free immunosensing for the detection of the C-terminal telopeptide bone turnover marker from type-1 collagen. A self-assembled monolayer (SAM) of dithiodipropionic acid was deposited on a gold electrode. Then streptavidin and biotinylated anti-human C-terminal telopeptide antibody were successively conjugated on the self-assembled monolayer. Electrochemical impedance measurements were made to characterize each step of the SAM/streptavidin/biotinylated antibody binding. Subsequently, electrochemical impedance was measured with different concentrations of C-teminal telopeptide. A detection limit of 50 ng/mL and a dynamic range up to 3 μg/mL were achieved. To our knowledge, this is the first attempt to develop a label-free immunosensor based on electrochemical impedance with DC bias for detection of bone-related degradation and rebuilding products. The electronic biosensor might eventually be used for quantitative point-of-care screening of bone health. It is hoped that analysis of bone turnover markers can indicate the beginning of bone diseases such as osteoarthritis and osteoporosis so that treatment might start early when it is most effective.

Objective: To investigate the safety and efficacy of elagolix, an oral gonadotropin-releasing hormone antagonist, with hormonal add-back therapy for up to 12 months in women with heavy menstrual bleeding associated with uterine leiomyomas.Methods: Elaris UF-EXTEND was a phase 3 extension study that evaluated an additional 6 months (up to 12 months total) of elagolix 300 mg twice daily with hormonal add-back therapy (estradiol 1 mg and norethindrone acetate 0.5 mg once daily) in women who completed an initial 6 months of the same treatment in one of two preceding phase 3 studies. The primary endpoint was the percentage of women with both less than 80 mL menstrual blood loss during final month and a 50% or greater reduction in menstrual blood loss from baseline to final month. Safety evaluations included adverse events and bone mineral density changes. The planned sample size of UF-EXTEND was based on estimated rollover and discontinuation rates in the two preceding studies.Results: From September 2016 to March 2019, 433 women were enrolled in UF-EXTEND. Of these women, 218 received up to 12 months of elagolix with add-back therapy; the mean±SD age of this group was 42.4±5.4 years and 67.3% were black. The percentage of women who met the primary endpoint in this elagolix with add-back group was 87.9% (95% CI [83.4-92.3]). The most frequently reported adverse events with up to 12 months of elagolix plus add-back therapy were hot flush (6.9%), night sweats (3.2%), headache (5.5%), and nausea (4.1%). Mean percent decreases in bone mineral density from baseline to extension month 6 were significantly less with elagolix plus add-back therapy than with elagolix alone {between-group difference in lumbar spine: -3.3 (95% CI [-4.1 to -2.5])}.Conclusion: Up to 12 months of elagolix with add-back therapy provided sustained reduction in menstrual blood loss in women with uterine leiomyomas, with the addition of add-back therapy attenuating the hypoestrogenic effects of elagolix alone.

Study Design: Retrospective cohort study of the Own the Bone database which is a fracture liaison service designed to improve recognition and treatment of osteoporosis.Objective: To use the Own the Bone (OTB) database to 1) examine the specific demographics of patients presenting with a low-energy clinical vertebral fracture (VFX) and 2) compare demographic and fracture-specific risk factors between patients with clinical VFX versus patients with nonvertebral low-energy fracture (NVFX).Summary Of Background Data: Large database studies have described risk factors for developing VFX. It is well described that a history of previous VFX portends an increased risk of future VFX. Few studies have reported cohorts from a fracture liaison service such as the OTB initiative.Methods: 35,039 unique cases of fragility fracture occurred between 2009 and 2016 and were included in analysis. VFX accounted for 3395 (9.9%) of the presenting fractures at OTB enrollment. The demographics, lifestyle factors, medication use, and fracture-specific data for patients in the OTB registry with vertebral fractures were summarized and then statistically compared to those with nonvertebral fragility fractures.Results: The majority of VFX patients were Caucasian, postmenopausal women (74.4%). There was an increased likelihood of presenting with a vertebral fracture in patients who sustained a previous VFX after the age of 50, while patients who sustained a prior nonvertebral fracture (NVFX) were more likely to present with a subsequent NVFX. After controlling for patients with a history of fracture after the age of 50, VFX patients (vs. NVFX) were more likely to be age 70-79, class 1 obesity, with a history of taking anti-osteoporotic prescription medications.Conclusions: Multiple factors were associated with a significantly increased risk of VFX compared with NVFX. Understanding the risk factors unique to fragility VFX is a critical component for targeting "at-risk" patients and preventing future osteoporosis-related fractures and their consequences.Level Of Evidence: 4.

Background: Uterine fibroids are hormone-responsive neoplasms that are associated with heavy menstrual bleeding. Elagolix, an oral gonadotropin-releasing hormone antagonist resulting in rapid, reversible suppression of ovarian sex hormones, may reduce fibroid-associated bleeding.Methods: We conducted two identical, double-blind, randomized, placebo-controlled, 6-month phase 3 trials (Elaris Uterine Fibroids 1 and 2 [UF-1 and UF-2]) to evaluate the efficacy and safety of elagolix at a dose of 300 mg twice daily with hormonal "add-back" therapy (to replace reduced levels of endogenous hormones; in this case, estradiol, 1 mg, and norethindrone acetate, 0.5 mg, once daily) in women with fibroid-associated bleeding. An elagolix-alone group was included to assess the impact of add-back therapy on the hypoestrogenic effects of elagolix. The primary end point was menstrual blood loss of less than 80 ml during the final month of treatment and at least a 50% reduction in menstrual blood loss from baseline to the final month; missing data were imputed with the use of multiple imputation.Results: A total of 412 women in UF-1 and 378 women in UF-2 underwent randomization, received elagolix or placebo, and were included in the analyses. Criteria for the primary end point were met in 68.5% of 206 women in UF-1 and in 76.5% of 189 women in UF-2 who received elagolix plus add-back therapy, as compared with 8.7% of 102 women and 10% of 94 women, respectively, who received placebo (P<0.001 for both trials). Among the women who received elagolix alone, the primary end point was met in 84.1% of 104 women in UF-1 and in 77% of 95 women in UF-2. Hot flushes (in both trials) and metrorrhagia (in UF-1) occurred significantly more commonly with elagolix plus add-back therapy than with placebo. Hypoestrogenic effects of elagolix, especially decreases in bone mineral density, were attenuated with add-back therapy.Conclusions: Elagolix with add-back therapy was effective in reducing heavy menstrual bleeding in women with uterine fibroids.

Objective: To evaluate elagolix, an oral gonadotropin-releasing hormone receptor antagonist, alone or with add-back therapy, in premenopausal women with heavy menstrual bleeding (greater than 80 mL per month) associated with uterine leiomyomas.Methods: This double-blind, randomized, placebo-controlled, parallel-group study evaluated efficacy and safety of elagolix in cohorts 1 (300 mg twice daily) and 2 (600 mg daily) with four arms per cohort: placebo, elagolix alone, elagolix with 0.5 mg estradiol/0.1 norethindrone acetate, and elagolix with 1.0 mg estradiol/0.5 mg norethindrone acetate. A sample size of 65 per group was planned to compare elagolix with add-back to placebo on the primary end point: the percentage of women who had less than 80 mL menstrual blood loss and 50% or greater reduction in menstrual blood loss from baseline to the last 28 days of treatment. Safety assessments included changes in bone mineral density.Results: From April 8, 2013, to December 8, 2015, 571 women were enrolled, 567 were randomized and treated (cohort 1=259; cohort 2=308), and 80% and 75% completed treatment, respectively. Participants had a mean±SD age of 43±5 years (cohort 2, 42±5 years), and 70% were black (cohort 2, 74%). Primary end point responder rates in cohort 1 (cohort 2) were 92% (90%) for elagolix alone, 85% (73%) for elagolix with 0.5 mg estradiol/0.1 mg norethindrone acetate, 79% (82%) for elagolix with 1.0 mg estradiol/0.5 mg norethindrone acetate, and 27% (32%) for placebo (all P<.001 vs placebo). Elagolix groups had significant decreases compared with placebo in lumbar spine bone mineral density, which was attenuated by adding 1.0 mg estradiol/0.5 mg norethindrone acetate.Conclusion: Elagolix with and without add-back significantly reduced menstrual blood loss in women with uterine leiomyomas. Add-back therapy reduced hypoestrogenic effects on bone mineral density.Clinical Trial Registration: ClinicalTrials.gov, NCT01817530; EU Clinical Trial Register, 2013-000082-37.

Objective: To evaluate the efficacy and safety of elagolix, an oral, nonpeptide gonadotropin-releasing hormone antagonist, over 12 months in women with endometriosis-associated pain.Methods: Elaris Endometriosis (EM)-III and -IV were extension studies that evaluated an additional 6 months of treatment after two 6-month, double-blind, placebo-controlled phase 3 trials (12 continuous treatment months) with two elagolix doses (150 mg once daily and 200 mg twice daily). Coprimary efficacy endpoints were the proportion of responders (clinically meaningful pain reduction and stable or decreased rescue analgesic use) based on average monthly dysmenorrhea and nonmenstrual pelvic pain scores. Safety assessments included adverse events, clinical laboratory tests, and endometrial and bone mineral density assessments. The power of Elaris EM-III and -IV was based on the comparison to placebo in Elaris EM-I and -II with an expected 25% dropout rate.Results: Between December 28, 2012, and October 31, 2014 (Elaris EM-III), and between May 27, 2014, and January 6, 2016 (Elaris EM-IV), 569 participants were enrolled. After 12 months of treatment, Elaris EM-III responder rates for dysmenorrhea were 52.1% at 150 mg once daily (Elaris EM-IV 550.8%) and 78.2% at 200 mg twice daily (Elaris EMIV 575.9%). Elaris EM-III nonmenstrual pelvic pain responder rates were 67.5% at 150 mg once daily (Elaris EM-IV 566.4%) and 69.1% at 200 mg twice daily (Elaris EM-IV 567.2%).”After 12 months of treatment, Elaris EM-III dyspareunia responder rates were 45.2% at 150 mg once daily (Elaris EM-IV=45.9%) and 60.0% at 200 mg twice daily (Elaris EM-IV=58.1%). Hot flush was the most common adverse event. Decreases from baseline in bone mineral density and increases from baseline in lipids were observed after 12 months of treatment. There were no adverse endometrial findings.Conclusion: Long-term elagolix treatment provided sustained reductions in dysmenorrhea, nonmenstrual pelvic pain, and dyspareunia. The safety was consistent with reduced estrogen levels and no new safety concerns were associated with long-term elagolix use.Clinical Trial Registration: ClinicalTrials.gov, NCT01760954 and NCT02143713.

Fractures may be associated with higher morbidity in obese postmenopausal women than in nonobese women. We compared health-care utilization, functional status, and health-related quality of life (HRQL) in obese, nonobese, and underweight women with fractures. Information from the GLOW study, started in 2006, was collected at baseline and at 1, 2, and 3 years. In this subanalysis, self-reported incident clinical fractures, health-care utilization, HRQL, and functional status were recorded and examined. Women in GLOW (n = 60,393) were aged ≥55 years, from 723 physician practices at 17 sites in 10 countries. Complete data for fracture and body mass index were available for 90 underweight, 3,270 nonobese, and 941 obese women with one or more incident clinical fractures during the 3-year follow-up. The median hospital length of stay, adjusted for age, comorbidities, and fracture type, was significantly greater in obese than nonobese women (6 vs. 5 days, p = 0.017). Physical function and vitality score were significantly worse in obese than in nonobese women, both before and after fracture; but changes after fracture were similar across groups. Use of antiosteoporosis medication was significantly lower in obese than in nonobese or underweight women. In conclusion, obese women with fracture undergo a longer period of hospitalization for treatment and have poorer functional status and HRQL than nonobese women. Whether these differences translate into higher economic costs and adverse effects on longer-term outcomes remains to be established. [ABSTRACT FROM AUTHOR]

Objective: To examine when, where and how fractures occur in postmenopausal women. Methods: We analyzed data from the Global Longitudinal Study of Osteoporosis in Women (GLOW), including women aged ≥55 years from the United States of America, Canada, Australia and seven European countries. Women completed questionnaires including fracture data at baseline and years 1, 2 and 3. Results: Among 60,393 postmenopausal women, 4122 incident fractures were reported (86% non-hip, non-vertebral [NHNV], 8% presumably clinical vertebral and 6% hip). Hip fractures were more likely to occur in spring, with little seasonal variation for NHNV or spine fractures. Hip fractures occurred equally inside or outside the home, whereas 65% of NHNV fractures occurred outside and 61% of vertebral fractures occurred inside the home. Falls preceded 68–86% of NHNV and 68–83% of hip fractures among women aged ≤64 to ≥85 years, increasing with age. About 45% of vertebral fractures were associated with falls in all age groups except those ≥85 years, when only 24% occurred after falling. Conclusion: In this multi-national cohort, fractures occurred throughout the year, with only hip fracture having a seasonal variation, with a higher proportion in spring. Hip fractures occurred equally within and outside the home, spine fractures more often in the home, and NHNV fractures outside the home. Falls were a proximate cause of most hip and NHNV fractures. Postmenopausal women at risk for fracture need counseling about reducing potentially modifiable fracture risk factors, particularly falls both inside and outside the home and during all seasons of the year.

Abstract: Introduction: Many women at risk of fracture do not receive anti-osteoporosis medication (AOM), while others may be receiving unnecessary treatment. Purpose: To examine the characteristics associated with AOM use among women at low and high risks of fracture. Methods: The Global Longitudinal Study of Osteoporosis in Women (GLOW) is a prospective cohort study in which data were collected, via self-administered questionnaires, from 60,393 non-institutionalized women aged ≥55years in 10 countries between October 1, 2006 and April 30, 2008. This is a cross-sectional analysis of baseline USA data, in which women were classified as having low fracture risk (<65years; no FRAX risk factors) or high fracture risk (≥65years; prior fracture or ≥2 other FRAX risk factors). Results: Of 27,957 women, 3013 were at low risk of fracture and 3699 were at high risk. Only 35.7% of high-risk women reported AOM treatment, rising to 39.5% for those with self-reported osteopenia and 65.4% for those with self-reported osteoporosis. Conversely, 13.4% of low-risk women reported AOM, rising to 28.7% for osteopenia and 62.4% for osteoporosis. Characteristics associated with significantly higher AOM treatment rates among low- and high-risk women were: osteoporosis (odds ratios 75.3 and 18.1, respectively), osteopenia (17.9 and 6.3), concern about osteoporosis (2.0 and 1.8), higher perceived risk of fracture (2.3 and 1.6), and higher vitality score (1.7 and 1.6). Conclusion: Use of AOM is frequently inconsistent with published guidelines in both high- and low-risk women. Characteristics other than FRAX fracture risk appear to influence this use, particularly the presence of self-reported osteoporosis. [Copyright &y& Elsevier]

Abstract: Mechanical loads play a pivotal role in the growth and maintenance of bone and joints. Although loading can activate anabolic genes and induce bone remodeling, damping is essential for preventing traumatic bone injury and fracture. In this study we investigated the damping capacity of bone, joint tissue, muscle, and skin using a mouse hindlimb model of enhanced loading in conjunction with finite element modeling to model bone curvature. Our hypothesis was that loads were primarily absorbed by the joints and muscle tissue, but that bone also contributed to damping through its compression and natural bending. To test this hypothesis, fresh mouse distal lower limb segments were cyclically loaded in axial compression in sequential bouts, with each subsequent bout having less surrounding tissue. A finite element model was generated to model effects of bone curvature in silico. Two damping-related parameters (phase shift angle and energy loss) were determined from the output of the loading experiments. Interestingly, the experimental results revealed that the knee joint contributed to the largest portion of the damping capacity of the limb, and bone itself accounted for approximately 38% of the total phase shift angle. Computational results showed that normal bone curvature enhanced the damping capacity of the bone by approximately 40%, and the damping effect grew at an accelerated pace as curvature was increased. Although structural curvature reduces critical loads for buckling in beam theory, evolution apparently favors maintaining curvature in the tibia. Histomorphometric analysis of the tibia revealed that in response to axial loading, bone formation was significantly enhanced in the regions that were predicted to receive a curvature-induced bending moment. These results suggest that in addition to bone''s compressive damping capacity, surrounding tissues, as well as naturally-occurring bone curvature, also contribute to mechanical damping, which may ultimately affect bone remodeling and bone quality.

Objectives To determine the proportion of untreated women who reported receiving treatment after incident fracture and to identify factors that predict treatment across an international spectrum of individuals. Design Prospective observational study. Self-administered questionnaires were mailed at baseline and 1 year. Setting Multinational cohort of noninstitutionalized women recruited from 723 primary physician practices in 10 countries. Participants Sixty thousand three hundred ninety-three postmenopausal women aged 55 and older were recruited with a 2:1 oversampling of women aged 65 and older. Measurements Data collected included participant demographics, medical history, fracture occurrence, medications, and risk factors for fracture. Anti-osteoporosis medications ( AOMs) included estrogen, selective estrogen receptor modulators, bisphosphonates, calcitonin, parathyroid hormone, and strontium. Results After the first year of follow-up, 1,075 women reported an incident fracture. Of these, 17% had started AOM, including 15% of those with a single fracture and 35% with multiple fractures. Predictors of treatment included baseline calcium use ( P = .01), baseline diagnosis of osteoporosis ( P < .001), and fracture type ( P < .001). In multivariable analysis, women taking calcium supplements at baseline (odds ratio ( OR) = 1.67) and with a baseline diagnosis of osteoporosis ( OR = 2.55) were more likely to be taking AOM. Hip fracture ( OR = 2.61), spine fracture ( OR = 6.61), and multiple fractures ( OR = 3.79) were associated with AOM treatment. Age, global region, and use of high-risk medications were not associated with treatment. Conclusion More than 80% of older women with new fractures were not treated, despite the availability of AOM. Important factors associated with treatment in this international cohort included diagnosis of osteoporosis before the incident fracture, spine fracture, and to a lesser degree, hip fracture.

This study examined patients' risk profiles and adherence to treatment in relation to the effect of risedronate and raloxifene on hip fracture incidence. Administrative billing data were used to follow two cohorts of women aged 65 and older after starting therapy with either risedronate (n = 86,735) or raloxifene (n = 37,726). The fracture risk profile was described using a 6-month history period before starting therapy. Effectiveness of each therapy was evaluated by comparing the incidence of hip fractures during the first 3 months with the subsequent 12 months among women adherent (medication possession ratio >80%) compared with those non-adherent to treatment. At the start of therapy, the raloxifene cohort was younger than the risedronate cohort (median age 73 vs. 76 years) and had fewer prior fractures (p < 0.01 for both). In the first 3 months of therapy, hip fracture incidence was lower in the raloxifene group (0.51 per 100 person-years) compared with the risedronate group (0.94 per 100 person-years). In the subsequent 12 months, the incidence of hip fractures decreased among patients adherent to the risedronate regimen [relative risk (RR) 0.70, 95% CI 0.59-0.84, p < 0.01] and did not change significantly among patients adherent to the raloxifene regimen (RR 1.02, 95% CI 0.73-1.44). In poorly adherent patients, neither drug decreased hip fracture risk. Risedronate treatment in adherent patients rapidly decreased the risk of hip fractures, whereas raloxifene treatment did not.

The article focuses on proper handling and long-term care of patients suffering from osteoporosis with prior fracture. It states that the proper management of the disease is critical to prevent risks for recurrent fractures. The World health Organization (WHO) has introduced fracture prediction algorithm (FRAX) to be able to absolutely predict fracture risks using the body mass index of the patient. Discussions of the other possible therapies that may be applied for osteoporosis are provided.
