Prior fragility fractures are associated with a higher risk of 8-year complications following total shoulder arthroplasty. Osteoporos Int 2024; 35:1767-1772. [PMID: 38900164 DOI: 10.1007/s00198-024-07147-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Accepted: 06/08/2024] [Indexed: 06/21/2024]
Abstract
Patients who sustain fragility fractures prior to total shoulder arthroplasty have significantly higher risk for bone health-related complications within 8 years of procedure. Identification of these high-risk patients with an emphasis on preoperative, intraoperative, and postoperative bone health optimization may help minimize these preventable complications. PURPOSE As the population ages, more patients with osteoporosis are undergoing total shoulder arthroplasty (TSA), including those who have sustained a prior fragility fracture. Sustaining a fragility fracture before TSA has been associated with increased risk of short-term revision rates, periprosthetic fracture (PPF), and secondary fragility fractures but long-term implant survivorship in this patient population is unknown. Therefore, the purpose of this study was to characterize the association of prior fragility fractures with 8-year risks of revision TSA, periprosthetic fracture, and secondary fragility fracture. METHODS Patients aged 50 years and older who underwent TSA were identified in a large national database. Patients were stratified based on whether they sustained a fragility fracture within 3 years prior to TSA. Patients who had a prior fragility fracture (7631) were matched 1:1 to patients who did not based on age, gender, Charlson Comorbidity Index (CCI), smoking, obesity, diabetes mellitus, and alcohol use. Kaplan-Meier and Cox Proportional Hazards analyses were used to observe the cumulative incidences of all-cause revision, periprosthetic fracture, and secondary fragility fracture within 8 years of index surgery. RESULTS The 8-year cumulative incidence of revision TSA (5.7% vs. 4.1%), periprosthetic fracture (3.8% vs. 1.4%), and secondary fragility fracture (46.5% vs. 10.1%) were significantly higher for those who had a prior fragility fracture when compared to those who did not. On multivariable analysis, a prior fragility fracture was associated with higher risks of revision (hazard ratio [HR], 1.48; 95% confidence interval [CI], 1.24-1.74; p < 0.001), periprosthetic fracture (HR, 2.98; 95% CI, 2.18-4.07; p < 0.001) and secondary fragility fracture (HR, 8.39; 95% CI, 7.62-9.24; p < 0.001). CONCLUSIONS Prior fragility fracture was a significant risk factor for revision, periprosthetic fracture, and secondary fragility fracture within 8 years of primary TSA. Identification of these high-risk patients with an emphasis on preoperative and postoperative bone health optimization may help minimize these complications. LEVEL OF EVIDENCE III.

Osteoporos Int 2024; 35:1497-1511. [PMID: 38740589 DOI: 10.1007/s00198-024-07078-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Accepted: 03/27/2024] [Indexed: 05/16/2024]
Abstract
PURPOSE This systematic review seeks to evaluate the proportion of fragility fracture patients screened in secondary fracture prevention programs who were indicated for pharmacological treatment, received prescriptions for bone-active medications, and initiated the prescribed medication. Additionally, the study aims to analyze equity in pharmacological treatment by examining equity-related variables including age, sex, gender, race, education, income, and geographic location. METHODS We conducted a systematic review to ascertain the proportion of fragility fracture patients indicated for treatment who received prescriptions and/or initiated bone-active medication through secondary fracture prevention programs. We also examined treatment indications reported in studies and eligibility criteria to confirm patients who were eligible for treatment. To compute the pooled proportions for medication prescription and initiation, we carried out a single group proportional meta-analysis. We also extracted the proportions of patients who received a prescription and/or began treatment based on age, sex, race, education, socioeconomic status, location, and chronic conditions. RESULTS This review included 122 studies covering 114 programs. The pooled prescription rate was 77%, and the estimated medication initiation rate was 71%. Subgroup analysis revealed no significant difference in treatment initiation between the Fracture Liaison Service and other programs. Across all studies, age, sex, and socioeconomic status were the only equity variables reported in relation to treatment outcomes. CONCLUSION Our systematic review emphasizes the need for standardized reporting guidelines in post-fracture interventions. Moreover, considering equity stratifiers in the analysis of health outcomes will help address inequities and improve the overall quality and reach of secondary fracture prevention programs.

Abstract
Introduction: Vertebral compression fractures (VCFs) pose a considerable healthcare burden and are linked to elevated morbidity and mortality. Despite available anti-osteoporotic treatments (AOTs), guideline adherence is lacking. This study aims to evaluate subsequent hip fracture incidence after index VCF and to elucidate AOT prescribing patterns in VCF patients, further assessing the impact of surgical interventions on these patterns. Materials and Methods: Patients with index VCFs between 2010 and 2021 were identified using the PearlDiver database. Diagnostic and procedural data were recorded using International Classification of Diseases (ICD-9, ICD-10) and Current Procedural Terminology (CPT) codes. Patients under age 50 and follow-up

Abstract
To determine and appraise the certainty of fracture liaison service (FLS) in reducing the risk of secondary fragility fractures in older adults aged ≥ 50 years and to examine the nature of the FLS and the roles of various disciplines involved in the delivery of the FLS. Medline, EMBASE, PubMed, CINAHL, SCOPUS, and The Cochrane Library were searched from January 1st, 2010, to May 31st, 2022. Two reviewers independently extracted data. The risk of bias was evaluated using the Newcastle-Ottawa Scale for cohort studies and the PEDro scale for randomized trials, while the GRADE approach established the certainty of the evidence. Thirty-seven studies were identified of which 34 (91.9%) were rated as having a low risk of bias and 22 (59.5%) were meta-analyzed. Clinically important low certainty evidence at 1 year (RR 0.26, CI 0.13 to 0.52, 6 pooled studies) and moderate certainty evidence at ≥ 2 years (RR 0.68, CI 0.55 to 0.83, 13 pooled studies) indicate that the risk of secondary fragility fracture was lower in the FLS intervention compared to the non-FLS intervention. Sensitivity analyses with no observed heterogeneity confirmed these findings. This review found clinically important moderate certainty evidence showing that the risk of secondary fragility fracture was lower in the FLS intervention at ≥ 2 years. More high-quality studies in this field could improve the certainty of the evidence. Review registration: PROSPERO-CRD42021266408.

Li D, Mao SS, Budoff MJ. Trabecular bone mineral density as measured by thoracic vertebrae predicts incident hip and vertebral fractures: the multi-ethnic study of atherosclerosis. Osteoporos Int 2024; 35:1061-1068. [PMID: 38519739 DOI: 10.1007/s00198-024-07040-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 02/12/2024] [Indexed: 03/25/2024]
Abstract
We evaluated the relationship of bone mineral density (BMD) by computed tomography (CT), to predict fractures in a multi-ethnic population. We demonstrated that vertebral and hip fractures were more likely in those patients with low BMD. This is one of the first studies to demonstrate that CT BMD derived from thoracic vertebrae can predict future hip and vertebral fractures. PURPOSE/INTRODUCTION Osteoporosis affects an enormous number of patients, of all races and both sexes, and its prevalence increases as the population ages. Few studies have evaluated the association between the vertebral trabecular bone mineral density(vBMD) and osteoporosis-related hip fracture in a multiethnic population, and no studies have demonstrated the predictive value of vBMD for fractures. METHOD We sought to determine the predictive value of QCT-based trabecular vBMD of thoracic vertebrae derived from coronary artery calcium scan for hip fractures in the Multi-Ethnic Study of Atherosclerosis(MESA), a nationwide multicenter cohort included 6814 people from six medical centers across the USA and assess if low bone density by QCT can predict future fractures. Measures were done using trabecular bone measures, adjusted for individual patients, from three consecutive thoracic vertebrae (BDI Inc, Manhattan Beach CA, USA) from non-contrast cardiac CT scans. RESULTS Six thousand eight hundred fourteen MESA baseline participants were included with a mean age of 62.2 ± 10.2 years, and 52.8% were women. The mean thoracic BMD is 162.6 ± 46.8 mg/cm3 (95% CI 161.5, 163.7), and 27.6% of participants (n = 1883) had osteoporosis (T-score 2.5 or lower). Over a median follow-up of 17.4 years, Caucasians have a higher rate of vertebral fractures (6.9%), followed by Blacks (4.4%), Hispanics (3.7%), and Chinese (3.0%). Hip fracture patients had a lower baseline vBMD as measured by QCT than the non-hip fracture group by 13.6 mg/cm3 [P < 0.001]. The same pattern was seen in the vertebral fracture population, where the mean BMD was substantially lower 18.3 mg/cm3 [P < 0.001] than in the non-vertebral fracture population. Notably, the above substantial relationship was unaffected by age, gender, race, BMI, hypertension, current smoking, medication use, or activity. Patients with low trabecular BMD of thoracic vertebrae showed a 1.57-fold greater risk of first hip fracture (HR 1.57, 95% CI 1.38-1.95) and a nearly threefold increased risk of first vertebral fracture (HR 2.93, 95% CI 1.87-4.59) compared to normal BMD patients. CONCLUSION There is significant correlation between thoracic trabecular BMD and the incidence of future hip and vertebral fracture. This study demonstrates that thoracic vertebrae BMD, as measured on cardiac CT (QCT), can predict both hip and vertebral fractures without additional radiation, scanning, or patient burden. Osteopenia and osteoporosis are markedly underdiagnosed. Finding occult disease affords the opportunity to treat the millions of people undergoing CT scans every year for other indications.

Abstract
Hip fractures exceed 250,000 cases annually in the United States, with the worldwide incidence projected to increase by 240-310% by 2050. Hip fractures are predominantly diagnosed by radiologist review of radiographs. In this study, we developed a deep learning model by extending the VarifocalNet Feature Pyramid Network (FPN) for detection and localization of proximal femur fractures from plain radiography with clinically relevant metrics. We used a dataset of 823 hip radiographs of 150 subjects with proximal femur fractures and 362 controls to develop and evaluate the deep learning model. Our model attained 0.94 specificity and 0.95 sensitivity in fracture detection over the diverse imaging dataset. We compared the performance of our model against five benchmark FPN models, demonstrating 6-14% sensitivity and 1-9% accuracy improvement. In addition, we demonstrated that our model outperforms a state-of-the-art transformer model based on DINO network by 17% sensitivity and 5% accuracy, while taking half the time on average to process a radiograph. The developed model can aid radiologists and support on-premise integration with hospital cloud services to enable automatic, opportunistic screening for hip fractures.

Abstract
OBJECTIVES With management of comorbidity in people living with HIV (PLWH) a key component of clinical care, early loss of bone integrity and clinical fracture are recognized as important issues. This review aims to describe the epidemiology of fracture in PLWH, as well as summarizing the relative balance of factors that contribute to fracture. We also aim to describe fracture risk assessment and interventional strategies to modify the risk of fracture in this population. RESULTS Data from recent meta-analyses show that PLWH have significantly more fractures than the general population, with men and injecting drug users at higher risk. Modifiable factors that contribute to fracture risk in this cohort include body mass index (BMI), drug use, concurrent medications, frailty, and hepatitis C virus infection. Relating to antiretroviral therapy, current or ever tenofovir exposure has been identified as predictive of fracture but not cumulative use, and a potentially modest protective effect of efavirenz has been observed. Fracture Risk Assessment Tool scores underestimate fracture risk in PLWH with improved accuracy when HIV is considered a cause of secondary osteoporosis and bone mineral density (BMD) included. CONCLUSION Early consideration of risk, prompting evaluation of modifiable risk factors, frailty and falls risk with bone density imaging and prompt intervention may avert fracture in PLWH. Guidance on screening and lifestyle modification is available in international guidelines. Bisphosphonates are safe and effective in PLWH, with limited data for other agents.

Abstract
INTRODUCTION Existing data on fragility spinal fractures prevalence in liver transplant candidates are scarce and inconsistent. This may be due to other comorbidities, besides hepatic osteodystrophy (HO), that contribute to bone loss and fragility fracture prevalence in chronic liver disease (CLD). OBJECTIVES The aim of this study was to investigate the prevalence of spinal thoracic and lumbar fragility fractures among cirrhotic, non-chronic kidney disease (CKD), non-diabetic liver transplant candidates and to explore their relationship with clinical characteristics, laboratory markers and dual-energy x-ray absorptiometry (DXA) results. MATERIAL AND METHODS This cross-sectional observational study was conducted at Merkur University Hospital, Croatia, between February 2019 and May 2023. Adult patients with liver cirrhosis referred for liver transplantation were included. Patients with acute infection, CKD, diabetes mellitus, malignancies, inflammatory bone diseases and those on corticosteroid or antiresorptive therapy were excluded. Clinical, laboratory and radiological assessment was carried out and patients were accordingly allocated into non-fractured and fractured group for the purpose of statistical analysis. RESULTS A total of 90 patients were included in the study. There was 123 fractures, 87 (70.7 %) in the thoracic and 36 (29.3 %) in the lumbar region. Eighty-nine (72.4 %) fractures were grade 1, 31 (25.2 %) were grade 2 and 3 (2.4 %) were grade 3. Patients in the fractured group were significantly older (p < 0.001). No significant differences between fractured and non-fractured group according to laboratory and DXA parameters were noted. Subgroup with lumbar fractures had significantly lower bone mineral density values at L1-L4 region. Statistically significant negative correlation between bone specific alkaline phosphatase (BALP) and hip total BMD (rho = -0.414, p < 0.001) and spine total BMD (rho = -0.258, p = 0.014) values was found. CONCLUSION Present study confirmed detrimental impact of CLD and HO on bone strength. DXA measurement correlated with the presence of lumbar fragility fractures. A combination of standard X-ray imaging and DXA is needed for adequate bone evaluation in pretransplant period and BALP could be useful for detecting HO in CLD. Searching for other risk factors and implementing bone turnover markers and additional imaging techniques for bone loss evaluation in liver transplant candidates is needed.

Cheng TA, Lai PH, Chuang HC, Hsu KL, Kuan FC, Su WR, Hong CK. Predictors of in-hospital mortality in older patients undergoing distal femur fracture surgery: A case-control study. SICOT J 2023; 9:36. [PMID: 38059859 DOI: 10.1051/sicotj/2023035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 11/19/2023] [Indexed: 12/08/2023] Open
Abstract
INTRODUCTION Geriatric fractures including distal femur and hip fractures are associated with high mortality rates. Currently, prognostic factors for in-hospital postoperative mortality are not identified. We aimed to evaluate overall in-hospital mortality and related potential risk factors in elderly patients who underwent distal femur fracture surgery. MATERIALS AND METHODS A retrospective cohort study of patients older than 60 years, who underwent distal femur fracture surgery between January 01, 2003, and December 31, 2021, was conducted. A case-control study was conducted to compare two age-matched groups of elderly patients of equivalent ages at a 1:4 ratio. The in-hospital mortality rate was calculated and potential confounders were compared between groups. RESULTS A total of 170 patients were enrolled; five died during hospital stay after undergoing surgery, yielding a 2.94% in-hospital mortality rate. Twenty patients who did not die were included in the control group. Patients' demographics were similar. The case-control comparison showed that the time from injury to surgery, preoperative hemoglobin level, estimated glomerular filtration rate (eGFR), and white blood cell count were significant factors correlated with in-hospital mortality. DISCUSSION The overall in-hospital mortality rate was 2.94%. Significant risk factors for in-hospital mortality included a longer time from injury to surgery, lower preoperative hemoglobin level and eGFR, and higher preoperative white blood cell count. In conclusion, preoperative comprehensive geriatric assessment, including cognitive, nutritional, and frailty status, should also be considered in the elderly fracture care model.

Abstract
Background: Milk proteins (MPs) and their derivative whey proteins (WPs) are important components of human diet that might prevent bone loss. We aimed to investigate the effects of MP on the bones of postmenopausal women, along with the effects of WP on osteoblast cells. Methods: We conducted a feasibility controlled clinical study with 62 postmenopausal women who were asked to consume an MP-enriched ice cream. We also investigated the effect of WP on the ERK1/2 and AKT pathways, RUNX2, alkaline phosphatase, RANKL/OPG ratio, and COL1A of Saos-2. Results: After 12 weeks, we found a greater bone mineral density and bone alkaline phosphatase reduction in women who consumed the MP-enriched ice cream compared to the control group (p = 0.03 and p = 0.02, respectively). In Saos-2 cells, WP upregulated ERK1/2 and AKT pathways (p = 0.002 and p = 0.016), cell proliferation (p = 0.03), and osteoblast differentiation markers, along with downregulating RANKL/OPG (p < 0.001). Moreover, the inhibition of ERK1/2 by PD184253 reverted the effects on both the RUNX2 and ALP mRNA expression and cells proliferation (p = 0.028, p = 0.004, and p = 0.003, respectively) when treated with WP. Conclusions: WP upregulates cell proliferation, RUNX2, and alkaline phosphatase through the activation of the ERK1/2 pathways on Saos-2. These mechanisms probably contribute to preventing bone loss in postmenopausal women.

Abstract
Osteoporosis is a common condition in which deteriorating bone tissue results in an increased risk of low trauma fracture. Influenced by the role of estrogen in building and maintaining bone mineral density, women have different patterns of bone accrual and loss compared with men, resulting in a lower peak bone mass and a greater lifetime fracture risk. Moreover, fracture risk increases significantly in postmenopausal women who have depleted estrogen levels. Osteoporotic fractures pose serious consequences-ranging from an inability to perform basic tasks and an increased risk of repeat fracture to the need for assisted living and even death. There is also a large economic toll associated with the health care costs required for post-fracture care. The Society for Women's Health Research (SWHR) convened an interdisciplinary Bone Health Working Group to review the current state of science and practice concerning women's bone health and osteoporosis care and to explore strategies to address gaps in screening, diagnosis, and treatment of bone disease in women. Women's bone health care must shift its paradigm from one of postmenopausal and post-fracture care to a preventive model that engages touchpoints throughout the lifespan. To achieve this paradigm shift, the Working Group recommends prioritizing efforts to build public awareness and clinical education of preventive bone health care for women, increase access to screening tools, improve patient-provider communication, and treat osteoporosis using a broader risk stratification approach.

Multiscale Femoral Neck Imaging and Multimodal Trabeculae Quality Characterization in an Osteoporotic Bone Sample. MATERIALS (BASEL, SWITZERLAND) 2022; 15:8048.

Abstract
Although multiple structural, mechanical, and molecular factors are definitely involved in osteoporosis, the assessment of subregional bone mineral density remains the most commonly used diagnostic index. In this study, we characterized bone quality in the femoral neck of one osteoporotic patients as compared to an age-matched control subject, and so used a multiscale and multimodal approach including X-ray computed microtomography at different spatial resolutions (pixel size: 51.0, 4.95 and 0.9 µm), microindentation and Fourier transform infrared spectroscopy. Our results showed abnormalities in the osteocytes lacunae volume (358.08 ± 165.00 for the osteoporotic sample vs. 287.10 ± 160.00 for the control), whereas a statistical difference was found neither for shape nor for density. The osteoporotic femoral head and great trochanter reported reduced elastic modulus (Es) and hardness (H) compared to the control reference (−48% (p < 0.0001) and −34% (p < 0.0001), respectively for Es and H in the femoral head and −29% (p < 0.01) and −22% (p < 0.05), respectively for Es and H in the great trochanter), whereas the corresponding values in the femoral neck were in the same range. The spectral analysis could distinguish neither subregional differences in the osteoporotic sample nor between the osteoporotic and healthy samples. Although, infrared spectroscopic measurements were comparable among subregions, and so regardless of the bone osteoporotic status, the trabecular mechanical properties were comparable only in the femoral neck. These results illustrate that bone remodeling in osteoporosis is a non-uniform process with different rates in different bone anatomical regions, hence showing the interest of a clear analysis of the bone microarchitecture in the case of patients’ osteoporotic evaluation.

Abstract
MRI could be applied for bone microarchitecture assessment; however, this technique is still suffering from low resolution compared to the trabecular dimension. A clear comparative analysis between MRI and X-ray microcomputed tomography (μCT) regarding microarchitecture metrics is still lacking. In this study, we performed a comparative analysis between μCT and 7T MRI with the aim of assessing the image resolution effect on the accuracy of microarchitecture metrics. We also addressed the issue of air bubble artifacts in cadaveric bones. Three fresh cadaveric femur heads were scanned using 7T MRI and µCT at high resolution (0.051 mm). Samples were submitted to a vacuum procedure combined with vibration to reduce the volume of air bubbles. Trabecular interconnectivity, a new metric, and conventional histomorphometric parameters were quantified using MR images and compared to those derived from µCT at full resolution and downsized resolutions (0.102 and 0.153 mm). Correlations between bone morphology and mineral density (BMD) were evaluated. Air bubbles were reduced by 99.8% in 30 min, leaving partial volume effects as the only source of bias. Morphological parameters quantified with 7T MRI were not statistically different (p > 0.01) to those computed from μCT images, with error up to 8% for both bone volume fraction and trabecular spacing. No linear correlation was found between BMD and all morphological parameters except trabecular interconnectivity (R2 = 0.69 for 7T MRI-BMD). These results strongly suggest that 7T MRI could be of interest for in vivo bone microarchitecture assessment, providing additional information about bone health and quality.

Abstract
PURPOSE OF REVIEW In this paper, we discuss how recent advancements in image processing and machine learning (ML) are shaping a new and exciting era for the osteoporosis imaging field. With this paper, we want to give the reader a basic exposure to the ML concepts that are necessary to build effective solutions for image processing and interpretation, while presenting an overview of the state of the art in the application of machine learning techniques for the assessment of bone structure, osteoporosis diagnosis, fracture detection, and risk prediction. RECENT FINDINGS ML effort in the osteoporosis imaging field is largely characterized by "low-cost" bone quality estimation and osteoporosis diagnosis, fracture detection, and risk prediction, but also automatized and standardized large-scale data analysis and data-driven imaging biomarker discovery. Our effort is not intended to be a systematic review, but an opportunity to review key studies in the recent osteoporosis imaging research landscape with the ultimate goal of discussing specific design choices, giving the reader pointers to possible solutions of regression, segmentation, and classification tasks as well as discussing common mistakes.

Abstract
PURPOSE The International Osteoporosis Foundation (IOF) formulated a set of best practice framework as an international benchmark for secondary fracture prevention (SFP) and fracture liaison services (FLS), delineating essential elements of service delivery. The aim of this audit was to assess compliance with the IOF standards for patients ≥ 50 years presenting with fragility hip fractures at a tertiary care center in Pakistan. METHODS A retrospective sample of hip fracture cases from Jan 2019 to Dec 2019, treated at the section of Orthopedic Surgery, Aga Khan University, Karachi, was conducted. After excluding high energy trauma cases and patients younger than 50 years of age, medical records were audited, using a pre-structured Performa based on IOF standards. Compliance level of 0, 1, 2, and 3 was recorded as defined by IOF. Microsoft excel was used for data analysis. RESULTS A compliance level of 3 was recorded for patient identification and fall prevention services, whereas level 1 was attained for database maintenance for 25 (100%) cases. For medication initiation, level 0 was recorded for all the cases; however, 8 (32%) cases were prescribed calcium and vitamin D supplements. For the standards, including post-fracture assessment timing, evaluation of secondary causes of osteoporosis, multifaceted assessment, medication review, communication strategy, and long-term management, a level 0 was noted for 25 (100%) cases. Moreover, no recommended assessment guidelines were followed uniformly. CONCLUSION The care gaps identified require substantial efforts to ensure adequate implementation of the overall best practice standards for SFP, necessitating the need for FLS initiation and establishment of fracture care pathway.

Abstract
BACKGROUND Impaired orthostatic blood pressure response and syncope confer a high risk of falls and trauma. The relationship between a history of unexplained syncope and orthostatic hypotension (OH) with subsequent fractures, however, has not been thoroughly examined. In this study, we aimed to investigate the relationship between previous hospital admissions due to unexplained syncope and OH and incident fractures in a middle-aged population. METHODS We analysed a large population-based prospective cohort of 30,399 middle-aged individuals (age, 57.5 ± 7.6; women, 60.2%). We included individuals hospitalised due to unexplained syncope or OH as the main diagnosis. Multivariable-adjusted Cox regression analysis was applied to assess the impact of unexplained syncope and OH hospitalisations on subsequent incident fractures. RESULTS During a follow-up period of 17.8 + 6.5 years, 8201 (27%) subjects suffered incident fractures. The mean time from baseline and first admission for syncope (n = 493) or OH (n = 406) was 12.6 ± 4.2 years, and the mean age of the first hospitalisation was 74.6 ± 7.4 years. Individuals with incident fractures were older, more likely to be women, and had lower BMI, higher prevalence of prevalent fractures, and family history of fractures. Multivariable-adjusted Cox regression showed an increased risk of incident fractures following hospitalisations due to unexplained syncope (HR 1.20; 95% CI 1.02-1.40; p = 0.025) and OH (HR 1.42; 95% CI 1.21-1.66; p < 0.001) compared with unaffected individuals. CONCLUSIONS Individuals hospitalised due to unexplained syncope and orthostatic hypotension have an increased risk of subsequent fractures. Our findings suggest that such individuals should be clinically assessed for their syncope aetiology, with preventative measures aimed at fall and fracture risk assessment and management.

Abstract
Introduction: Low-energy falls are the leading cause of injury-related morbidity and mortality in the elderly. In the past, physicians focused on treating fractures resulting from falls rather than preventing them. The purpose of this study is to identify patients with a hospital encounter for fall prior to a fracture as an opportunity for pre-injury intervention when patients might be motivated to engage in falls prevention. Materials & Methods: A retrospective analysis of all emergency room and inpatient encounters in 2016 with an ICD10 diagnosis code including “fall” across a tri-state health system was performed. Subsequent encounters with diagnosis of fracture within 2 years were then identified. Data was collected for time to subsequent fracture, fracture type and location, and length of stay of initial encounter. Results: There were 12,382 encounters for falls among 10,589 patients. Of those patients, 1,040 (9.8%) sustained a subsequent fracture. Fractures were most commonly lower extremity fractures (661 fractures; 63.5%), including hip fractures (447 fractures; 45.87%). Median time from fall to fracture was 105 days (IQR 16-359 days). Discussion: Falls are an important, modifiable risk factor for fragility fracture. This study demonstrates that patients are presenting to the hospital with one of the main modifiable risk factors for fracture within a time window that allows for intervention. Conclusions: Presentation to the hospital for a fall is a vital opportunity to intervene and prevent subsequent fracture in a high-risk population.

Abstract
Osteoporosis is a bone disease characterized by chronic pain and recurrent fractures. Osterix is a transcription factor regulating bone formation. miR-214 was found to have a role in skeletogenesis. Our goal was to investigate the possible role of miR-214 in primary osteoporosis through osterix. Their expression was determined in bone samples obtained from primary osteoporotic patients (n = 26) and age- and sex-matched controls (n = 14). Additionally, their expression was correlated to the laboratory and clinical parameters of the study participants. Differential expression of osterix and miR-214 was detected in the osteoporotic group compared to controls. While miR-214 was significantly higher, osterix was significantly lower. In primary osteoporotic patients, relative quantification value of osterix was positively correlated with sex, body mass index, and ionized calcium and negatively correlated with miR-214 and C-reactive protein. Thus, the role of miR-214 in primary osteoporosis could be through inhibiting osterix expression in bones and therefore both miR-214 and osterix could be targets for future therapeutic intervention.
