RESUMO

BACKGROUND: Despite the existence of effective treatments and prescribed therapeutic protocols, there is a lack of management of osteoporosis, resulting in increased secondary morbidity and mortality. The general practitioner (GP) is the first-line practitioner for the detection and management of osteoporosis. OBJECTIVE: This study was conducted to explore the practices, knowledge, and difficulties in postmenopausal osteoporosis management reported by GPs. METHODS: An anonymous questionnaire (19 questions) was created via Google Forms and distributed to 300 GPs via social networks (WhatsApp, Facebook, and Gmail). The survey results were automatically calculated on "Google Forms" and checked using SPSS.20 software. RESULTS: A total of 129 responses were received, representing a response rate of 43%. The majority of respondents were women (67.2%). The definition of osteoporosis was variable, with 51.6% defining it as a T-score of ≤-2.5 SD, 25.8% defining it as diffuse bone demineralization, and 12.1% defining it as a fracture after falling with low energy. Prolonged corticosteroid therapy was the most commonly indicated reason for measuring bone mineral density (BMD) (81.39%). The calcium phosphate balance was the most requested (90.1%). Vitamin D and calcium supplementation were reported by 74.41% and 54.26% of GPs, respectively. Fracture of the upper end of the femur was the main therapeutic indication (65.11%). Most GPs surveyed (73.3%) were unfamiliar with the fracture risk assessment tool (FRAX). Most of the GPs gave advice on fall prevention to their patients (83.72%), and 62.5% of GPs monitored their patients' height. Anti-osteoporosis treatment was maintained for 3 to 5 years by 44.96% of GPs. CONCLUSION: Our survey found that the practices and knowledge of GPs on osteoporosis vary widely and often deviate from the recommended standards. This highlights the need for more excellent education of GPs, due to their vital role in the management of osteoporosis.

RESUMO

Osteoporosis affects more than 200 million women worldwide, with postmenopausal women being particularly susceptible to this condition and its severe sequelae disproportionately, such as osteoporotic fractures. To date, the current focus has been more on symptomatic treatment, rather than preventive measures. To address this, we performed a meta-analysis aiming to identify potential predictors of osteoporotic fractures in postmenopausal women, with the ultimate goal of identifying high-risk patients and exploring potential therapeutic approaches. We searched Embase, MEDLINE and Cochrane with search terms (postmenopausal AND fracture) AND ("risk factor" OR "predictive factor") in May 2022 for cohort and case-control studies on the predictors of osteoporotic fracture in postmenopausal women. Ten studies with 1,287,021 postmenopausal women were found eligible for analyses, in which the sample size ranged from 311 to 1,272,115. The surveyed date spanned from 1993 to 2021. Our results suggested that age, BMI, senior high school and above, parity ≥ 3, history of hypertension, history of diabetes mellitus, history of alcohol intake, age at menarche ≥ 15, age at menopause < 40, age at menopause > 50, estrogen use and vitamin D supplements were significantly associated with osteoporotic fracture in postmenopausal women. Our findings facilitate the early prediction of osteoporotic fracture in postmenopausal women and may contribute to potential therapeutic approaches. By focusing on preventive strategies and identifying high-risk individuals, we can work toward reducing the burden of osteoporosis-related fractures in this vulnerable population.

RESUMO

Presently, postmenopausal osteoporosis mainly caused by excessive activation of in vivo osteoclasts has become a global public health burden. Natural compounds have gradually become the potential drugs for the treatment of postmenopausal osteoporosis. Aloperine is a new alkaloid extracted from the leaves and seeds of sophora bean. The current studies have proved that aloperine has many biological activities, including anti-inflammatory, antiviral and anticancer activities. This study shows that aloperine can inhibit activity and formation of osteoclast mediated by RANKL in a dose-dependent manner without affecting the activity of bone marrow macrophages (BMM). In addition, it is found that aloperine can inhibit the expression of osteoclast specific marker genes, including nuclear factor of activated T cells cytoplasmic 1 (NFATc1), tartrate resistant acid phosphatase (TRAcP), matrix metallopeptidase 9 (MMP9), cathepsin K (Ctsk), V-ATPase d2 and calcitonin receptor. The in vitro experiment of aloperine proved that aloperine can inhibit the degradation of IκBα and the phosphorylation of P65, ERK and JNK. Additionally, aloperine improves bone loss in ovariectomized (OVX) mice by inhibiting osteoclast activity. This project proved that aloperine can affect the formation of osteoclasts by inhibiting RANKL signaling channel, and it is indicated that aloperine has the potential to be developed as a new drug for the prevention and treatment of postmenopausal osteoporosis.

RESUMO

The menopausal transition is a critical period in women's lives. Exercise might be the most promising non-pharmaceutic intervention to address the large variety of risk factors related to the pronounced estradiol decline during peri- and early-postmenopause. The aim of this study was to determine the effect of an 18-month multipurpose exercise program on risk factors and symptoms related to the menopausal transition. Fifty-four women 1-5 years postmenopause with osteopenia or osteoporosis were randomly assigned 1) to a high impact weight-bearing/high-intensity/velocity resistance training group (EG: n=27) exercising three times a week or 2) to an attendance control group (CG: n=27) that performed low-intensity exercise once a week. Both groups were supplemented with cholecalciferol and calcium. The primary study endpoint was bone mineral density (BMD) at lumbar spine (LS) and total hip, secondary outcomes were lean body mass (LBM), total and abdominal body percentage, metabolic syndrome Z-Score (MetS-Z), menopausal symptoms and muscle strength and power. Due to COVID-19, the study was stopped after 13 months. We observed significant effects for BMD-LS (EG: 0.002±.018 versus CG: -.009±0.018 mg/cm2, p=0.027) but not for BMD total hip (EG: -0.01±.016 versus CG: -.009±0.020 mg/cm2, p=0.129). LBM improved significantly in the EG and decreased in the CG (0.39±1.08 vs -0.37±1.34 kg, p=0.026). Total and abdominal body fat improved significantly in the EG and was maintained in the CG (-1.44±1.49 vs -0.02±1.55 kg, p=0.002 and -1.50±2.33 vs 0.08±2.07 kg, p=0.011). Significant effects in favor of the EG were also determined for menopausal symptoms (p=0.029), hip/leg extension strength (p<0.001) and power (p<0.001). However, changes of the MetS-Z did not differ significantly (p=0.149) between EG and CG. In summary, with minor exceptions, we demonstrated the effectiveness of a multipurpose exercise protocol dedicated to early-postmenopausal women on various risk factors and complaints related to the menopausal transition.

RESUMO

CONTEXT: In the Denosumab and High-Dose Teriparatide Administration (DATA-HD) study, we reported that 15 months of combined high-dose (HD) teriparatide and denosumab increased mean areal bone mineral density (aBMD) at the hip and spine more than combined denosumab and standard-dose (SD) teriparatide. OBJECTIVE: In the current analysis, we compare the individual rates of aBMD response between the treatment groups. DESIGN: Single-site, open-label, randomized controlled trial in which postmenopausal women received either teriparatide 20-µg daily (SD) or 40-µg daily (HD) given months 0 through 9, overlapped with denosumab 60 mg, given months 3 through 15 (15 months' total duration). The proportion of participants in the SD and HD groups experiencing total hip, femoral neck, and lumbar spine aBMD gains of >3%, >6%, and >9% were compared. PARTICIPANTS: Postmenopausal women with osteoporosis completing all study visits (n = 60). MAIN OUTCOME MEASURE(S): aBMD (dual x-ray absorptiometry). RESULTS: At the end of the 15-month treatment period, a higher proportion of women in the HD group had aBMD increases >3% (83% vs. 58%, P = .037) and >6% (45% vs. 19%, P = .034) at the total hip, and >3% at the femoral neck (86% vs. 63%, P = .044). At the lumbar spine, >3% response rates were similar, whereas the >6% and >9% response rates were greater in the HD group (100% vs. 79%, P = .012 and 93% vs. 59%, P = .003, respectively). CONCLUSION: Compared with the SD regimen, more women treated with the HD regimen achieved clinically meaningful and rapid gains in hip and spine aBMD. These results suggest that this approach may provide unique benefits in the treatment of postmenopausal osteoporosis.

RESUMO

PURPOSE: Aromatase inhibitors (AIs) represent the first-line adjuvant therapy for hormone receptor-positive breast cancer (BC) women. AIs have been associated with an increased rate of fractures. The aim of our study was to investigate trabecular bone score (TBS) and bone quantitative ultrasound (QUS) measurements as bone quality surrogates in AIs users. METHODS: Sixty postmenopausal BC women starting AIs and forty-two controls (mean age 61.64 ± 8.33 years) were considered. Bone mineral density (BMD) at lumbar spine and femoral neck and TBS were measured by DXA; QUS-derived Amplitude-Dependent Speed of Sound (AD-SoS), Bone Transmission Time (BTT), and Ultrasound Bone Profile Index (UBPI) were assessed at phalangeal site; morphometric vertebral fractures (Vfx) by X-ray, serum bone-specific alkaline phosphatase (BSAP), and C-telopeptide of type 1 collagen (CTX) were also evaluated. RESULTS: After 18 months, changes of TBS vs baseline were significantly different between AIs group and controls [Δ TBS - 2.2% vs - 0.4%, respectively, p = 0.001]. AD-SoS, BTT and UBPI values decreased only in AIs' group (- 3.7%, - 6.45%, -8.5%, vs baseline, respectively, pall < 0.001). 3 Vfx occurred in AIs users and were associated with the greater TBS and AD-SoS modifications. In the AIs' group, ΔTBS was associated with ΔAD-SoS (r = 0.58, p < 0.001) and ΔUBPI (r = 0.415, p = 0.001), but not with ΔBMD. Moreover, ΔTBS was independently predicted by ΔAD-SoS, after correcting for BMD, CTX and BSAP level changes (ß = 0.37, SE = 2.44, p < 0.001). CONCLUSIONS: TBS and phalangeal QUS provide useful information related to bone quality in AI-treated BC survivors and could be considered for fracture risk evaluation.

RESUMO

The phase III DATA study investigates the efficacy of adjuvant anastrozole (6 vs. 3 year) in postmenopausal women with breast cancer previously treated with 2-3 years of tamoxifen. This planned side-study assessed patterns of care regarding detection and treatment of osteopenia/osteoporosis, and trends in bone mineral density (BMD) during and after therapy. We registered all BMD measurements and bisphosphonate-use. Time to osteopenia/osteoporosis was analysed by Kaplan Meier methodology. For the trend in T-scores we used linear mixed models with random patients effects. Of 1860 eligible DATA patients, 910 (48.9%) had a baseline BMD measurement. Among patients with a normal baseline BMD (n = 417), osteopenia was observed in 53.5% and 55.4% in the 6- and 3-year group respectively (p = 0.18), during follow-up. Only two patients (3-year group) developed osteoporosis. Of the patients with osteopenia at baseline (n = 408), 24.4% and 20.4% developed osteoporosis respectively (p = 0.89). Three years after randomisation 18.3% and 18.2% used bisphosphonates in the 6- and 3-year groups respectively and 6 years after randomisation this was 23.7% and 20.9% respectively (p = 0.90) of which the majority used oral bisphosphonates. The yearly mean BMD-change during anastrozole in the lumbar spine showed a T-score decline of 0.075. After bisphosphonate addition the decline became less prominent (0.047 (p < 0.001)) and after anastrozole cessation, while continuing bisphosphonates, the mean BMD yearly increased (0.047 (p < 0.001)). In conclusion, extended anastrozole therapy was not associated with a higher incidence of osteoporosis. Anastrozole-use was associated with a BMD decrease; however, the decline was modest and partially reversible after anastrozole cessation.

RESUMO

Purpose To investigate whether assessment of bone strength with quantitative computed tomography (CT) in combination with dual-energy x-ray absorptiometry (DXA) is cost-effective as a screening tool for osteoporosis in postmenopausal women. Materials and Methods A state-transition microsimulation model of osteoporosis for postmenopausal women aged 55 years or older was developed with a lifetime horizon and U.S. societal perspective. All model inputs were derived from published literature. Three strategies were compared: no screening, DXA with T score-dependent rescreening intervals, and a combination of DXA and quantitative CT with different intervals (3, 5, and 10 years) at different screening initiation ages (55-65 years). Oral bisphosphonate therapy was started if DXA hip T scores were less than or equal to -2.5, 10-year risk for hip fracture was greater than 3% (World Health Organization Fracture Risk Assessment Tool score, or FRAX), 10-year risk for major osteoporotic fracture was greater than 20% (FRAX), quantitative CT femur bone strength was less than 3000 N, or occurrence of first fracture (eg, hip, vertebral body, wrist). Outcome measures were incremental cost-effectiveness ratios (ICERs) in 2015 U.S. dollars per quality-adjusted life year (QALY) gained and number of fragility fractures. Probabilistic sensitivity analysis was also performed. Results The most cost-effective strategy was combined DXA and quantitative CT screening starting at age 55 with quantitative CT screening every 5 years (ICER, $2000 per QALY). With this strategy, 12.8% of postmenopausal women sustained hip fractures in their remaining life (no screening, 18.7%; DXA screening, 15.8%). The corresponding percentages of vertebral fractures for DXA and quantitative CT with a 5-year interval, was 7.5%; no screening, 11.1%; DXA screening, 9%; for wrist fractures, 14%, 17.8%, and 16.4%, respectively; for other fractures, 22.6%, 30.8%, and 27.3%, respectively. In probabilistic sensitivity analysis, DXA and quantitative CT at age 55 years with quantitative CT screening every 5 years was the best strategy in more than 90% of all 1000 simulations (for thresholds of $50 000 per QALY and $100 000 per QALY). Conclusion Combined assessment of bone strength and bone mineral density is a cost-effective strategy for osteoporosis screening in postmenopausal women and has the potential to prevent a substantial number of fragility fractures. © RSNA, 2017 Online supplemental material is available for this article.

RESUMO

Electromagnetic fields (EMF) was considered as a non-invasive modality for treatment of osteoporosis while the effects were diverse with EMF parameters in time domain. In present study, we extended analysis of EMF characteristics from time domain to frequency domain, aiming to investigate effects of four kinds of EMF (LP (1-100 Hz), BP (100-3,000 Hz), HP (3,000-50,000 Hz) and AP (1-50,000 Hz)) on ovariectomized (OVX) osteoporosis (OP) in mice. Forty-eight 3-month-old female BALB/c mice were equally assigned to Sham, OVX, OVX + LP, OVX + BP, OVX + HP and OVX + AP groups (n = 8). After 8-week exposure (3 h/day), LP and BP significantly increased serum bone formation markers and osteogenesis-related gene expressions compared with OVX. Bedsides, LP and BP also slightly increased bone resorption activity compared with OVX, evidenced by increased RANKL/OPG ratio. HP sharply decreased serum bone formation and resporption markers and osteogenesis and osteoclastogenesis related gene expressions compared with OVX. AP had accumulative effects of LP, BP and HP, which significantly increased bone formation and decreased bone resporption activity compared with OVX. As a result, LP, BP and HP exposure did not later deterioration of bone mass, microarchitecture and mechanical strength in OVX mice with OP. However, AP stimulation attenuated OVX-induced bone loss.

RESUMO

PURPOSE: The aim of this work was to explore the risk factors for distal radius fracture in postmenopausal women. PATIENTS AND METHODS: A total of 611 postmenopausal women with distal radius fractures were included. In all, 173 patients with unstable distal radius fractures were included (unstable fracture group), while there were 438 patients with stable distal radius fractures (stable fracture group). The control group comprised 800 postmenopausal women with no fracture. A questionnaire survey was conducted. RESULTS: Compared with the control group, the 611 postmenopausal women with distal radius fractures had a higher body mass index (BMI). Advanced age and higher BMI were more common in the unstable fracture group than in the stable fracture group (P <0.05). A higher proportion of the 611 postmenopausal women with a distal radius fracture had fallen in the last 12 months than in the control group. Comorbidities and the frequency of falls in the last 12 months were higher in the unstable fracture group than in the stable fracture group (P < 0.05). A higher proportion of the control group was taking calcium supplements, while the proportion taking calcium supplementation in the unstable fracture group was lower than that in the stable fracture group (P < 0.05). Osteoporosis in the two fracture groups (P < 0.05) was significantly higher than in the control group and was the highest in the unstable fracture group (P < 0.05). CONCLUSIONS: In postmenopausal women, obesity, falls, unknown osteoporosis status, and osteoporosis are associated with high risk of distal radius fracture. If comorbidities and advanced age are also present, this group of persons may be at higher risk for unstable distal radius fractures.

RESUMO

BACKGROUND: Postmenopausal osteoporosis has been linked to accelerated cognitive decline; however, little is known about the effects of medical treatment on cognitive functions. MATERIAL AND METHODS: In this prospective study, we evaluated the effects of bisphosphonate treatment and calcium plus vitamin D supplementation on cognitive functions in 45 women with postmenopausal osteoporosis who were started on medical treatment. The medications included alendronate, zoledronic acid, risedronate, or ibandronic acid along with a low or high dose of calcium plus vitamin D supplements. The cognitive function was assessed by the mini-mental state examination (MMSE) test. All subjects underwent bone mineral density (BMD) measurement via dual-energy X-ray absorptiometry at baseline and at study completion. RESULTS: The mean T-score improved significantly at 1 year, except for neck of the femur area. The mean MMSE score did not change significantly at 12 months (26.40 ± 2.07 vs. 26.48 ± 2.07; p = 0.513), with no difference among bisphosphonates combined with calcium plus vitamin D. Higher dose (1200 mg/800 U/day) of calcium plus vitamin D supplementation tended to have a greater improvement as compared with lower dose (600 mg/400 U/day) (Δ MMSE: 0.11 ± 0.72 vs. -0.14 ± 0.69). CONCLUSIONS: Cognitive functions in the women remained unaltered, whereas bone BMD T-scores were significantly improved at the 12(th) month after the administration of bisphosphonates and calcium plus vitamin D supplements. Higher doses of calcium plus vitamin D supplements were likely to have better cognitive effects as compared with lower doses.

RESUMO

Traditional Chinese medicine (TCM) is a theoretical based system and is completely different from western medicine and states that numerous diseases, especially chronic diseases, are cured or relieved. "Zheng" (syndrome) is a summarization of the pathological changes which take place during the different stages of the development of a disease, including its location, cause and nature as well as the state of both Xie-qi (pathogenic factors) and Zheng-qi (healthy energy). Compared to a single symptom, syndrome can demonstrate the nature of a disease more extensively, completely and correctly. However, it is difficult to compare "Zheng" to the western medicine theory, which is based on scientific evidence for the diagnosis and treatment of a specific disease. Estrogen deficiency is a major pathogenetic factor in bone loss after menopause and oophorectomy with the subsequent risk of developing osteoporosis. According to TCM theory, the kidney stores essence and this can transform into bone marrow to nourish the bones, strenghthen the skeleton by promoting growth and repair. The kidney deficiency can decrease the estrogen level adjusted by the gonadal axis, causing osteoporosis. Traditional Chinese medicines tonifying the kidney can significantly enhance the level of estrogen to alleviate osteoporosis. In combination with other evidence, we further deduce that the syndrome as defined within TCM has a similar pathological mechanism to that defined by western medicine. If TCM theory is to be understood and accepted, and further fused with the western medicine theory, the micro pathological basis of TCM syndrome must be investigated extensively, which will lead to bridging the two theories together. The fusion of TCM with western medicine will pay more attention to analyzing the common nature and difference of disease and syndrome. This paper reviews the way forward for new translational advances.

RESUMO

Estrogen and bone health form a cornerstone of osteoporosis management. Diagnosis of osteoporosis is performed using bone mineral density (BMD), despite the limitations associated with this. Within the last 25 years, numerous bone turnover markers (BTM) have been developed, and this has led to a marked improvement in drug development for osteoporosis and understanding of fast bone losers. Estrogen research has provided landmark research on understanding the relationship between osteoporosis and BTMs. Clinical studies have illustrated how measurement of BTMs can assist in prediction of rapid bone loss, future fractures and, most importantly, the fracture efficacy of drugs. The BTMs provide information independent of BMD and fracture history. In addition, changes in bone turnover within 1 month predict later changes in BMD, which allows for early efficacy and prognostic measures. The aim is to provide a careful review of the possibilities that implementation of BTMs into clinical practice have provided, while placed in a historical context. The primary focus is on how the BTMs have revolutionized clinical trials on osteoporosis drugs through their ability to supplement bone mass measurements and fracture efficacy endpoints.

RESUMO

OBJECTIVES: The Medication Use Patterns, Treatment Satisfaction, and Inadequate Control of Osteoporosis Study (MUSIC OS-EU) was designed to better understand the rate and burden of gastrointestinal (GI) events on clinical and health care outcomes among postmenopausal women with osteoporosis. METHODS: MUSIC OS-EU is a prospective, multinational, observational cohort study of postmenopausal women ≥50 years of age diagnosed with osteoporosis and enrolled in physician clinics in six countries: France, Italy, the Netherlands, Sweden, the United Kingdom, and Canada. The MUSIC OS-EU study has three components: (i) a physician survey to describe their management of osteoporotic patients with GI events; (ii) a retrospective chart survey to describe the receipt and type of osteoporosis medication prescribed; and (iii) a prospective cohort study including untreated and treated patients diagnosed with osteoporosis to investigate the rate of GI events and association with osteoporosis medication use patterns, health-related quality of life, treatment satisfaction and resource utilisation among postmenopausal women with osteoporosis. RESULTS: Physicians at 97 sites completed the physician questionnaire and data for 716 patients were abstracted for the retrospective chart review. Enrolment and the baseline data collection for the prospective cohort study were conducted between March 2012 and June 2013 for 292 untreated and 2,959 treated patients, of whom 684 were new users and 2,275 were experienced users of oral osteoporosis medications. CONCLUSIONS: The results of MUSIC OS-EU will illuminate the association of GI events with the management of osteoporosis and with patient-reported outcomes among postmenopausal women with osteoporosis in Europe and Canada.

RESUMO

BACKGROUND: Osteoporosis (OP) and osteoarthritis (OA) are prevalent skeletal disorders among postmenopausal women. Coexistence is common especially that of postmenopausal osteoporosis (PMO) and lumbar OA. An hypothesis has been raised that OP and OA might share the same pathogenic mechanism, and pulsed electromagnetic fields (PEMFs) were reported to have anti-osteoporosis and anti-osteoarthritis properties, but this suggestion was based primarily on biomarker data. Therefore, whether these two effects could take place simultaneously has not yet been investigated. This randomized controlled trial (RCT) is designed to explore the effect of PEMFs for PMO and concomitant lumbar OA. METHODS/DESIGN: The study will include PMO patients (postmenopausal women; aged between 50 and 70 years; have been postmenopausal for at least 5 years and diagnosed with OP using proximal femur T-score) with concomitant lumbar OA (patients with confounding disorders like diabetes, hypertension, hyperlipidemia, and previous fracture history, etcetera, will be excluded) will be randomly assigned to two arms: PEMFs group and sham PEMFs group. There will be 25 participants in each arm (50 in total) and the outcome assessment, including the primary endpoint (proximal femur bone mineral density), will be performed at 5 weeks, 3 months and 6 months after enrollment. DISCUSSION: PMO and lumbar OA are prominent public health problem, especially for postmenopausal women. We hope this RCT will provide scientific evidence to primary care of the postmenopausal women regarding the use of these nonpharmaceutical, noninvasive modalities, PEMFs, in managing PMO and lumbar OA.

RESUMO

Trabecular bone score (TBS) is a recently-developed analytical tool that performs novel grey-level texture measurements on lumbar spine dual X-ray absorptiometry (DXA) images, and thereby captures information relating to trabecular microarchitecture. In order for TBS to usefully add to bone mineral density (BMD) and clinical risk factors in osteoporosis risk stratification, it must be independently associated with fracture risk, readily obtainable, and ideally, present a risk which is amenable to osteoporosis treatment. This paper summarizes a review of the scientific literature performed by a Working Group of the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis. Low TBS is consistently associated with an increase in both prevalent and incident fractures that is partly independent of both clinical risk factors and areal BMD (aBMD) at the lumbar spine and proximal femur. More recently, TBS has been shown to have predictive value for fracture independent of fracture probabilities using the FRAX® algorithm. Although TBS changes with osteoporosis treatment, the magnitude is less than that of aBMD of the spine, and it is not clear how change in TBS relates to fracture risk reduction. TBS may also have a role in the assessment of fracture risk in some causes of secondary osteoporosis (e.g., diabetes, hyperparathyroidism and glucocorticoid-induced osteoporosis). In conclusion, there is a role for TBS in fracture risk assessment in combination with both aBMD and FRAX.

RESUMO

UNLABELLED: We found that the fragility hip and vertebral fractures caused excess mortality rates in this Chinese female population, which was unexpectedly lower than those in western countries and other Asian countries. This was the first nationwide survey relating to post-fracture outcomes conducted among Chinese population in Mainland China. INTRODUCTION: This study aimed to investigate the mortality, self-care ability, diagnosis, and medication treatment of osteoporosis following fragility hip and vertebral fractures through a nationwide survey among female patients aged over 50 in Mainland China. METHODS: This was a multicenter, retrospective cohort study based on medical chart review and patient questionnaire. Female patients aged 50 or older admitted for low-trauma hip or vertebral fractures and discharged from Jan 1, 2008 to Dec 31, 2012 were followed. RESULTS: Total of 1151 subjects of hip fracture and 842 subjects of vertebral fracture were included. The mean age was 73.4 ± 10.0, and the median of duration from index fracture to interview was 2.6 years. The overall 1-year, 2-year, 3-year, 4-year, and 5-year cumulative mortality rates were 3.5, 7.0, 11.2, 13.1, and 16.9 %, respectively. The first year mortality rates in hip (3.8 %, 95% CI 3.3-4.4 %) and vertebral fracture (3.1 %, 95% CI 2.5-3.7 %) were significantly higher than that in the general population (1.6 %). Impaired self-care ability was observed in 33.2, 40.6, and 23.8 % of overall, hip fracture, and vertebral fracture group, respectively. The overall diagnosis rate of osteoporosis was 56.8 %, and bone mineral density (BMD) measurement had never been conducted in 42.0 % among these women. After the index fracture, 69.6 % of them received supplements and/or anti-osteoporotic medications, among which 39.6 % only received calcium with/without vitamin D supplementation. CONCLUSIONS: The osteoporotic hip and vertebral fractures caused excess mortality rates in this population of Mainland China. The current diagnosis and medical treatment following the fragility fractures is still insufficient in Mainland China.

RESUMO

Brazil has an aging population, with an associated increase in the prevalence of chronic diseases. Postmenopausal osteoporosis is of particular concern because it leads to an increased risk of fractures, with subsequent negative impacts on health in older women. In recent years, efforts have been made to better understand the epidemiology of osteoporosis in Brazil, and to manage both direct and indirect costs to the Brazilian health care system. The reported prevalence of osteoporosis among postmenopausal women in Brazil varies from 15% to 33%, depending on the study methodology and the use of bone densitometry data or self-reporting by participants. A diagnosis of osteoporosis can be made on the basis of fractures occurring without significant trauma or on the basis of low bone mineral density measured by dual energy X-ray absorptiometry. To reduce the risk of osteoporosis, all postmenopausal women should be encouraged to maintain a healthy lifestyle, which includes physical activity and a balanced diet. Smoking and alcohol use should also be addressed. Special attention should be given to interventions to reduce the risk of falls, especially among older women. Calcium intake should be encouraged, preferably through diet. The decision to recommend calcium supplementation should be made individually because there is concern about a possible increased risk of cardiovascular disease associated with this treatment. Brazilian women obtain a minimal amount of vitamin D from their diet, and supplementation is warranted in women with little exposure to solar ultraviolet-B radiation. For women diagnosed with osteoporosis, some form of pharmacologic therapy should be initiated. Compliance with treatment should be monitored, and the treatment period should be individualized for each patient. The Brazilian government provides medication for osteoporosis through the public health system free of charge, but without proper epidemiological knowledge, the implementation of public health programs is impaired.

RESUMO

PURPOSE: The ability of a pharmacy technician to support the patient screening and documentation-related functions of a pharmacist-driven osteoporosis management service was evaluated. METHODS: A two-phase prospective study was conducted within a large integrated health system to assess a pharmacy technician's performance in supporting a multisite team of clinical pharmacy specialists providing postfracture care. In phase I of the study, a specially trained pharmacy technician provided support to pharmacists at five participating medical offices, helping to identify patients requiring pharmacist intervention and, when applicable, collecting patient-specific clinical information from the electronic health record. In phase II of the study, the amount of pharmacist time saved through the use of technician support versus usual care was evaluated. RESULTS: The records of 127 patient cases were reviewed by the pharmacy technician during phase I of the study, and a pharmacist agreed with the technician's determination of the need for intervention in the majority of instances (92.9%). An additional 91 patient cases were reviewed by the technician in phase II of the research. With technician support, pharmacists spent less time reviewing cases subsequently determined as not requiring intervention (mean ± S.D., 5.0 ± 3.8 minutes per case compared with 5.2 ± 4.5 minutes under the usual care model; p = 0.78). In cases requiring intervention, technician support was associated with a reduction in the average pharmacist time spent on care plan development (13.5 ± 7.1 minutes versus 18.2 ± 16.6 minutes with usual care, p = 0.34). CONCLUSION: The study results suggest that a pharmacy technician can accurately determine if a patient is a candidate for pharmacist intervention and collect clinical information to facilitate care plan development.
