Abstract
Patients with inflammatory rheumatic and musculoskeletal diseases (iRMDs) such as rheumatoid arthritis, connective tissue diseases, vasculitides and spondyloarthropathies are at a higher risk of osteoporosis and fractures than are individuals without iRMDs. Research and management recommendations for osteoporosis in iRMDs often focus on glucocorticoids as the most relevant risk factor, but they largely ignore disease-related and general risk factors. However, the aetiopathogenesis of osteoporosis in iRMDs has many facets, including the negative effects on bone health of local and systemic inflammation owing to disease activity, other iRMD-specific risk factors such as disability or malnutrition (for example, malabsorption in systemic sclerosis), and general risk factors such as older age and hormonal loss resulting from menopause. Moreover, factors that can reduce fracture risk, such as physical activity, healthy nutrition, vitamin D supplementation and adequate treatment of inflammation, are variably present in patients with iRMDs. Evidence relating to general and iRMD-specific protective and risk factors for osteoporosis indicate that the established and very often used term 'glucocorticoid-induced osteoporosis' oversimplifies the complex inter-relationships encountered in patients with iRMDs. Osteoporosis in these patients should instead be described as 'multifactorial'. Consequently, a multimodal approach to the management of osteoporosis is required. This approach should include optimal control of disease activity, minimization of glucocorticoids, anti-osteoporotic drug treatment, advice on physical activity and nutrition, and prevention of falls, as well as the management of other risk and protective factors, thereby improving the bone health of these patients.

Osteoporosis management in adults with schizophrenia following index hip fracture event: a 10-year population-based retrospective cohort study, Ontario, Canada. Osteoporos Int 2024; 35:1289-1298. [PMID: 38760503 DOI: 10.1007/s00198-024-07123-3] [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: 09/27/2023] [Accepted: 05/08/2024] [Indexed: 05/19/2024]
Abstract
Little is known about the incidence of osteoporosis testing and treatment in individuals with schizophrenia, who may be more likely to fracture. Using competing risk models, we found that schizophrenia was associated with lower incidence of testing or treatment. Implications are for understanding barriers and solutions for this disadvantaged group. PURPOSE Evidence suggests that individuals with schizophrenia may be more likely to experience hip fractures than the general population; however, little is known about osteoporosis management in this disadvantaged subpopulation. Our study objective was to compare bone mineral density (BMD) testing and pharmacologic treatment in hip fracture patients with versus without schizophrenia. METHODS This was a retrospective population-based cohort study leveraging health administrative databases, and individuals aged 66-105 years with hip fracture between fiscal years 2009 and 2018 in Ontario, Canada. Schizophrenia was ascertained using a validated algorithm. The outcome was a composite measure of (1) pharmacologic prescription for osteoporosis; or (2) a BMD test. Inferential analyses were conducted using Fine-Gray subdistribution hazard regression, with mortality as the competing event. RESULTS A total of 52,722 individuals aged 66 to 105 years who sustained an index hip fracture in Ontario during the study period were identified, of whom 1890 (3.6%) had schizophrenia. Hip fracture patients with vs without schizophrenia were more likely to be long-term care residents (44.3% vs. 18.1%; standardized difference, 0.59), frail (62.5% vs. 36.5%; standardized difference, 0.54) and without a primary care provider (9.2% vs. 4.8%; standardized difference, 0.18). In Fine-Gray models, schizophrenia was associated with a lower incidence of testing or treatment (0.795 (0.721, 0.877)). CONCLUSIONS In this population-based retrospective cohort study, a schizophrenia diagnosis among hip fracture patients was associated with a lower incidence of testing or treatment, after accounting for mortality, and several enabling and predisposing factors. Further research is required to investigate barriers to osteoporosis management in this disadvantaged population.

[PMID: 38898155 DOI: 10.1007/s11657-024-01409-z] [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: 01/02/2024] [Accepted: 06/05/2024] [Indexed: 06/21/2024]
Abstract
This study examined the clinical characteristics and refracture rates of Colombian patients with high- and very high-risk osteoporosis. This reveals osteoporosis diagnoses and treatment gaps. Only 5.3% of the patients were diagnosed with osteoporosis at discharge and 70.5% had refractures. This finding underscores the need for national policies to enhance osteoporosis prevention and treatment. PURPOSE This study aimed to assess the clinical features and refracture rates among patients with high- and very-high-risk osteoporosis in Colombia, highlighting diagnostic and treatment gaps. METHODS A retrospective observational study was conducted using the medical records of patients aged ≥ 50 years who experienced fragility fractures between 2003 and 2022. Clinical and demographic characteristics at the time of the initial fracture were analyzed, as well as the subsequent imminent risk (refracture rate) and the diagnosis and treatment gap. RESULTS 303.982 fragility fractures occurred, and only 5.3% of patients were diagnosed with osteoporosis upon discharge. The most prevalent index fractures were forearm, vertebral, rib, and hip. Only 17.8% of the cohort had a matched osteoporosis diagnosis, indicating a low healthcare capture. Among the diagnosed patients, 10.08% were classified as high- and very high-risk of fracture, predominantly women with a mean age of 73 years. Comorbidities included diabetes, Sjögren's syndrome, and heart failure. The prevalence of osteoporosis has increased significantly from 2004 to 2022, possibly due to improved detection methods, an aging population, or a combination of both. Despite this increase, treatment delay was evident. Refractures affected 70.5% of the patients, with forearm, hip, humerus, and vertebral fractures being the most common, with a mean time of refracture of 7 months. CONCLUSION Significant delays were observed in the diagnosis and treatment of fragility fractures. Colombia's government and health system must address osteoporosis by implementing national policies that prioritize osteoporosis and fragility fracture prevention and reduce delays in diagnosis and treatment.

Abstract
The TBS is a new method for clinicians to assess the bone quality. It is directly related to the mechanical strength of bone and helps predict fracture risk. The present analysis aimed to investigate the associations between serum PTH levels and TBS by analyzing data from the National Health and Nutrition Examination Survey (NHANES). A total of 3516 participants from the NHANES 2005-2006 were included in this cross-sectional study. The independent variable was serum PTH, and the outcome variable was TBS. The associations of serum PTH levels with TBS were examined using multivariable linear regression models. After adjusting for covariates, there was a negative association between serum PTH level and TBS (β = - 0.0034; 95% confidence interval, - 0.0050 to - 0.0017). However, in the subgroup analysis stratified by gender, race, and age, this association became negative only in Non-Hispanic White (β = - 0.0047, 95% CI: - 0.0071 to - 0.0048) and young people (age < 60) (β = - 0.0036, 95% CI: - 0.0057, - 0.0016), regardless of gender. In addition, the association of serum PTH with TBS was an U-shaped curve, with a point of inflection at 6.71 pmol/L. This study showed that serum PTH level was negatively associated with TBS. Maintaining PTH levels in a lower reasonable clinical range may be beneficial to bone health, especially for young non-Hispanic white.

Abstract
PURPOSE OF REVIEW Recently, the American Diabetes Association updated the 2024 guidelines for Standards of Care in Diabetes and recommend that a T-score of - 2.0 in patients with diabetes should be interpreted as equivalent to - 2.5 in people without diabetes. We aimed to evaluate the most recent findings concerning the bone mineral density (BMD)-derived T-score and risk of fractures related to osteoporosis in subjects with diabetes. RECENT FINDINGS The dual-energy X-ray absorptiometry (DXA) scan is the golden standard for evaluating BMD. The BMD-derived T-score is central to fracture prediction and signifies both diagnosis and treatment for osteoporosis. However, the increased fracture risk in diabetes is not sufficiently explained by the T-score, complicating the identification and management of fracture risk in these patients. Recent findings agree that subjects with type 2 diabetes (T2D) have a higher T-score and higher fracture risk compared with subjects without diabetes. However, the actual number of studies evaluating the direct association of higher fracture risk at higher T-score levels is scant. Some studies support the adjustment based on the 0.5 BMD T-score difference between subjects with T2D and subjects without diabetes. However, further data from longitudinal studies is warranted to validate if the T-score treatment threshold necessitates modification to prevent fractures in subjects with diabetes.

Abstract
Importance A high proportion of patients who sustain a fracture have multimorbidity. However, the association of multimorbidity with postfracture adverse outcomes, such as subsequent fractures and premature mortality, has not been widely explored. Objective To examine the association of multimorbidity and self-rated health with subsequent fractures and mortality after fracture. Design, Setting, and Participants This prospective cohort study included participants from New South Wales, Australia, in the Sax Institute's 45 and Up Study (n = 267 357). Participants were recruited from July 2005 to December 2009 and followed up from the date of the incident fracture until subsequent fracture, death, or the end of the study (April 2017), whichever occurred first, with questionnaire data linked to hospital admission and medication records. Data analysis was reported between March and September 2023. Exposures Charlson Comorbidity Index (CCI) score and self-rated health (SRH). Main Outcomes and Measures The main outcomes were subsequent fracture or mortality after an incident fracture. Associations between SRH measures and subsequent fracture and mortality were also assessed. All analyses were stratified by sex given the different fracture and mortality risk profiles of females and males. Results Of 25 280 adults who sustained incident fractures, 16 191 (64%) were female (mean [SD] age, 74 [12] years) and 9089 (36%) were male (mean [SD] age, 74 [13] years). During a median follow-up time of 2.8 years (IQR, 1.1-5.2 years), 2540 females (16%) and 1135 males (12%) sustained a subsequent fracture and 2281 females (14%) and 2140 males (24%) died without a subsequent fracture. Compared with a CCI score of less than 2, those with a CCI score of 2 to 3 had an increased risk of subsequent fracture (females: hazard ratio [HR], 1.16 [95% CI, 1.05-1.27]; males: HR, 1.25 [95% CI, 1.09-1.43]) and mortality (females: HR, 2.19 [95% CI, 1.99-2.40]; males: HR, 1.89 [95% CI, 1.71-2.09]). Those with a CCI score of 4 or greater had greater risks of subsequent fracture (females: HR, 1.33 [95% CI, 1.12-1.58]; males: HR, 1.48 [95% CI, 1.21-1.81]) and mortality (females: HR, 4.48 [95% CI, 3.97-5.06]; males: HR, 3.82 [95% CI 3.41-4.29]). Self-rated health was also significantly associated with subsequent fracture and mortality. Those reporting the poorest health and quality of life had the highest subsequent fracture risks, and their mortality risks were even higher. Conclusions and Relevance In this cohort study, both CCI and SRH measures were associated with increased risk of subsequent fractures and mortality after fracture, underscoring the importance of managing the care of patients with comorbidities who sustain a fracture.

The impact of a Fracture Liaison Service after 3 years on secondary fracture prevention and mortality in a Portuguese tertiary center. Arch Osteoporos 2023; 19:4. [PMID: 38110537 DOI: 10.1007/s11657-023-01363-2] [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: 06/11/2023] [Accepted: 12/06/2023] [Indexed: 12/20/2023]
Abstract
Despite the establishment of Fracture Liaison Services (FLS) worldwide, no study has evaluated their impact on the Portuguese population. Our work has shown that the implementation of an FLS is associated with a significant increase in OP treatment and a lower risk of secondary fracture. PURPOSE Fracture Liaison Services (FLS) have been established worldwide, with positive effects on treatment, secondary fracture, mortality, and economic burden. However, no study has evaluated their impact on the Portuguese population. Therefore, we purposed to evaluate the effect of an FLS model in a Portuguese center on osteoporosis (OP) treatment, secondary fracture, and mortality rates, 3 years after a fragility fracture. METHODS Patients over 50 years old, admitted with a fragility fracture, between January 2017 and December 2020, were included in this retrospective study. Patients evaluated after FLS implementation (2019-2020) were compared with those evaluated before (2017-2018) and followed for 36 months. Predictors of secondary fracture and mortality were assessed using a multivariate Cox regression model, adjusted to potential confounders. RESULTS A total of 551 patients were included (346 before and 205 after FLS). The FLS significantly increased the rate of OP treatment, when compared with standard clinical practice (8.1% vs 77.6%). During follow-up, the secondary fracture rate was 14.7% and 7.3%, before and after FLS, respectively. FLS was associated with a lower risk of secondary fracture (HR 0.39, C.I. 0.16-0.92). Although we observed a lower mortality rate (25.1% vs 13.7%), FLS was not a significant predictor of survival. CONCLUSION Implementing the FLS model in a Portuguese center has increased OP treatment and reduced the risk of secondary fracture. We believe that our work supports adopting FLS models in national programs.
