Osteoporosis referral and treatment among people with severe mental illness: A ten-year data linkage study. J Psychiatr Res 2022; 147:94-102. [PMID: 35030512 DOI: 10.1016/j.jpsychires.2022.01.005] [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: 07/06/2021] [Revised: 11/17/2021] [Accepted: 01/03/2022] [Indexed: 11/24/2022]
Abstract
INTRODUCTION People with severe mental illness (SMI) are at increased risk of osteoporosis but minimal information is available on their treatment and referral. We investigated differences in these outcomes between patients with/without SMI in linked primary and specialist care data. METHODS People with SMI aged 18+ at diagnosis with both primary and mental healthcare records between 1st May 2009 and 31st May 2019 from a south London catchment were matched 1:4 to randomly selected controls on gender, age and duration of primary care follow-up. Outcomes included prescription of osteoporosis medications and referrals for osteoporosis, analysed using multivariable logistic regression analyses. RESULTS The study included 2269 people with SMI and 9069 matched non-SMI controls. People with SMI were more likely to have a recorded prescription of osteoporosis medications (odds ratio [OR] = 3.54, 95% confidence interval [CI] 2.87, 4.35) and be referred for osteoporosis (OR = 1.51, 95% CI 1.09, 2.08) within 2 years after the date of first SMI diagnosis after adjusting for ethnicity, deprivation and Charlson Comorbidity Index. Factors including older age (osteoporosis medications: OR = 1.04, 95% CI 1.03, 1.05; osteoporosis referral: OR = 1.05, 95% CI 1.04, 1.07) and being prescribed with Class A analgesics (osteoporosis medications: OR = 1.91, 95% CI 1.31, 2.77; osteoporosis referral: OR = 1.77, 95% CI 1.02, 3.07) are significant predictors for osteoporosis management pathways within SMI patients. CONCLUSION People with SMI are more frequently prescribed medications for osteoporosis and referred to osteoporosis screening than the general population. Given the many risk factors for osteoporosis in this group, this increased rate of referrals may well be warranted, and there is need to pay more attention to this at-risk group. Screening studies are needed to determine whether the rate of referral is proportional to the need.

Chen S, Dai M. Lipopolysaccharide-Induced lncRNA TMC3-AS1 is Highly Expressed in Osteoporosis and Promotes Osteoblast Apoptosis by Suppressing the Formation of Mature miR-708. Int J Gen Med 2022; 15:3345-3352. [PMID: 35368795 PMCID: PMC8964444 DOI: 10.2147/ijgm.s350081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Accepted: 01/10/2022] [Indexed: 11/23/2022] Open
Abstract
Background LncRNA TMC3-AS1 expression is affected by lipopolysaccharide (LPS), a contributor to osteoporosis (OS). Therefore, we hypothesized that TMC3-AS1 could inhibit osteoblast apoptosis and interact with miR-708, a regulator of osteoblast apoptosis in OS. Methods Differential expression of TMC3-AS1 and miR-708 (mature and premature) in OS patients and controls was analyzed using RT-qPCR. Subcellular location of TMC3-AS1 in osteoblasts was analyzed using subcellular fractionation assay. The direct interaction between TMC3-AS1 and premature miR-708 was analyzed using RNA pulldown assay. The role of TMC3-AS1 and miR-708 in the expression of each other was explored with overexpression assays. Cell apoptosis induced by LPS was analyzed using cell apoptosis assay. Results TMC3-AS1 and premature miR-708 were highly expressed in OS and were upregulated by LPS in osteoblasts. In contrast, mature miR-708 was under-expressed in OS and downregulated by LPS. TMC3-AS1 directly interacted with premature miR-708 and was detected in both the nuclear and cytoplasm fractions. TMC3-AS1 decreased premature miR-708 level and increased mature miR-708 level. Moreover, TMC3-AS1 increased LPS-induced cell apoptosis and suppressed the role of miR-708 in cell apoptosis. Conclusion TMC3-AS1 is highly expressed in OS and promotes LPS-induced osteoblast apoptosis by reducing miR-708 maturation.

Do Vitamin D receptor gene polymorphisms affect bone mass density in men?: A meta-analysis of observational studies. Ageing Res Rev 2022; 75:101571. [PMID: 35063697 DOI: 10.1016/j.arr.2022.101571] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2021] [Revised: 11/28/2021] [Accepted: 01/16/2022] [Indexed: 12/18/2022]
Abstract
The signs of aging in humans can often be detected through a decrease in bone mass density (BMD). The decrease in BMD as a risk of osteoporosis is often only seen in women, but not in men, even though men also have a risk of osteoporosis which can affect their well-being. We conducted study searches through databases such as PubMed, EBSCO, ProQuest, Willey Online, Science Direct, and SAGE. We performed analysis on four types of Vitamin D receptor polymorphisms: BsmI, ApaI, FokI, and TaqI from 14 potential studies involving men. We found that several genetic analysis models of BsmI and FokI significantly affected BMD in men: BB vs bb in whole body BMD (SMD = 0.43, 95% CI = [0.12-0.75], p = 0.0008, BB vs Bb in whole body BMD (SMD = -1.38, 95% CI = [-1.87 to 0.88], p < 0.00001), and FF+Ff vs ff spine BMD (SMD = 0.59, 95% CI = 0.13-1.05], p = 0.001), even after adjusting for comorbidities as confounding variables. The present meta-analysis showed that BsmI and FokI polymorphisms of the VDR gene were correlated with decreased BMD in men which may contribute to the aging process and well-being.

Bone manganese is a sensitive biomarker of ongoing elevated manganese exposure, but does not accumulate across the lifespan. ENVIRONMENTAL RESEARCH 2022; 204:112355.

Abstract
Studies have established associations between environmental and occupational manganese (Mn) exposure and executive and motor function deficits in children, adolescents, and adults. These health risks from elevated Mn exposure underscore the need for effective exposure biomarkers to improve exposure classification and help detect/diagnose Mn-related impairments. Here, neonate rats were orally exposed to 0, 25, or 50 mg Mn/kg/day during early life (PND 1-21) or lifelong through ∼ PND 500 to determine the relationship between oral Mn exposure and blood, brain, and bone Mn levels over the lifespan, whether Mn accumulates in bone, and whether elevated bone Mn altered the local atomic and mineral structure of bone, or its biomechanical properties. Additionally, we assessed levels of bone Mn compared to bone lead (Pb) in aged humans (age 41-91) living in regions impacted by historic industrial ferromanganese activity. The animal studies show that blood, brain, and bone Mn levels naturally decrease across the lifespan without elevated Mn exposure. With elevated exposure, bone Mn levels were strongly associated with blood Mn levels, bone Mn was more sensitive to elevated exposures than blood or brain Mn, and Mn did not accumulate with lifelong elevated exposure. Elevated early life Mn exposure caused some changes in bone mineral properties, including altered local atomic structure of hydroxyapatite, along with some biomechanical changes in bone stiffness in weanlings or young adult animals. In aged humans, blood Mn ranged from 5.4 to 23.5 ng/mL; bone Mn was universally low, and decreased with age, but did not vary based on sex or female parity history. Unlike Pb, bone Mn showed no evidence of accumulation over the lifespan, and may not be a biomarker of cumulative long-term exposure. Thus, bone may be a useful biomarker of recent ongoing Mn exposure in humans, and may be a relatively minor target of elevated exposure.

Delayed Diagnosis of a Tibial Stress Fracture Associated with Glucocorticoid and Methotrexate Therapy in a Patient with Rheumatoid Arthritis: A Case Report. JOURNAL OF ACUPUNCTURE RESEARCH 2022.

Abstract
The risk of stress fractures is associated with rheumatoid arthritis (RA), which can aggravate bone loss. We report the case of a patient who was on long-term medication for RA presenting with lower extremity pain on the left and swelling without trauma. Magnetic resonance imaging and plain radiographs at the previous hospital showed no signs of fracture, but radiographs performed later, revealed a stress fracture of the left distal tibia. The stress fracture may have occurred due to multiple reasons such as long-term use of methotrexate and glucocorticoids, active RA, postmenopausal state, and immobility. Suspicion of a stress fracture should not be ruled out especially in RA patients with persistent pain, even if the radiographical findings are normal. Additional imaging and follow-ups are essential. The patient’s pain was relieved with Korean medicine treatments, which suggests their potential application for stress fractures in RA patients.

Abstract
The use of anti-osteoporosis treatment following a diagnosis of osteoporosis with fracture or a relevant fragility fracture remains low in France. Initiating an anti-resorptive may reduce the incidence of a subsequent fracture by 60%. PURPOSE To describe real-world osteoporosis treatment patterns in individuals with a fragility fracture in France and to explore the impact of initiating treatment on the risk of subsequent fracture. METHODS A retrospective cohort study, using the national French Health Insurance claims database. Males and females 50 years and over, with a hospital discharge diagnosis of osteoporosis with fracture or a relevant fragility fracture between 2011 and 2014, were included and followed until death or the end of 2016, whichever came first. The primary outcome was the proportion of patients receiving anti-osteoporosis treatments prior to and post-index fracture. Change in fracture rates before and after treatment initiation was assessed in an exploratory analysis. RESULTS A total of 574,133 patients (138,567 males, 435,566 females) had a qualifying index fracture. The proportion of patients receiving any anti-osteoporosis treatment increased pre-index fracture to post-index fracture from 2.2 to 5.6% among males, and from 11.8 to 18.2% among females. Oral bisphosphonates were the most prescribed anti-osteoporosis treatment for both males and females among post-index fractures (60.6% and 68.8% of patients initiating treatment). Following initiation of anti-resorptives, the incidence of subsequent fracture was reduced by 60% (rate ratio (RR): 0.40, 95% confidence interval [CI]: 0.34-0.45). CONCLUSION Anti-osteoporosis treatment following an index fracture in France remains low. Improved identification and pharmacologic management of patients at risk of fragility fractures are necessary to reduce the risk of subsequent fractures.

Abstract
Our study was carried out to evaluate the effect of lipoic acid (LA) on the densitometric properties, structure and mechanical strength of the mandible of Wistar rats with developing osteopenia. The study used 42 sham-operated (SHO) and ovariectomized (OVX) rats. The OVX rats were randomly divided (n = 6) onto two controls treated subcutaneously with physiological saline (OVX-PhS) and 17β-estradiol (OVX-E2), respectively, and onto four experimental OVX groups that received LA in the doses of 12.5, 25, 50 and 100 mg/kg/day for 28 days. The results demonstrated that the lack of estrogen brought about osteopenic bone changes, especially in the trabecular compartment. In addition, while the usage of LA in the doses of 12.5 and 25 LA had no effect in OVX rats, the dose of 100 effectively inhibited osteopenic changes of the mandible. This dose maintained structural, densitometric and mechanical parameters at levels like that in the SHO and OVX-E2 groups by inhibiting the destructive influence of oxidative stress. Dose 50, however, was revealed to be the most effective. It not only inhibited atrophic changes and the influence of oxidative stress, but also stimulated the formation of mandibular bone tissue. Our results suggest that the administration of LA is effective in preventing atrophic changes in the mandibular bone tissue in conditions of ovarian hormone deficiency and suggest its potential in the therapy of osteoporosis.

Abstract
Osteoporosis is a chronical, systemic skeletal disorder characterized by an increase in bone resorption, which leads to reduced bone density. The reduction in bone mineral density and therefore low bone mass results in an increased risk of fractures. Osteoporosis is caused by an imbalance in the normally strictly regulated bone homeostasis. This imbalance is caused by overactive bone-resorbing osteoclasts, while bone-synthesizing osteoblasts do not compensate for this. In this review, the mechanism is presented, underlined by in vitro and animal models to investigate this imbalance as well as the current status of clinical trials. Furthermore, new therapeutic strategies for osteoporosis are presented, such as anabolic treatments and catabolic treatments and treatments using biomaterials and biomolecules. Another focus is on new combination therapies with multiple drugs which are currently considered more beneficial for the treatment of osteoporosis than monotherapies. Taken together, this review starts with an overview and ends with the newest approaches for osteoporosis therapies and a future perspective not presented so far.

BIOLOGY 2022; 11:biology11020189.

Abstract
Simple Summary In the first two years following spinal cord injury, people lose up to 50% of bone below the injury. This injury-induced bone loss significantly affects rehabilitation and leaves people vulnerable to fractures and post-fracture complications, including lung and urinary tract infections, blood clots in the veins, and depression. Unfortunately, little is known about the factors driving this bone loss. In fact, even though we know that injury, age, and sex independently increase bone loss, there have been no studies looking at the cumulative effects of these variables. People with spinal injury are aging, and the age at which injuries occur is increasing. It is essential to know whether these factors together will further compromise bone. To examine this, we assessed bone loss in young and old, male and female mice after spinal injury. As expected, we found that aging alone decreased motor activity and bone volume. Spinal injury also reduced bone volume, but it did not worsen the effects of age. Instead, injury effects appeared related to reduced rearing activity. The data suggest that although partial weight-bearing does not reduce bone loss after spinal cord injury, therapies that put full weight on the legs may be clinically effective. Abstract After spinal cord injury (SCI), 80% of individuals are diagnosed with osteopenia or osteoporosis. The dramatic loss of bone after SCI increases the potential for fractures 100-fold, with post-fracture complications occurring in 54% of cases. With the age of new SCI injuries increasing, we hypothesized that a SCI-induced reduction in weight bearing could further exacerbate age-induced bone loss. To test this, young (2–3 months) and old (20–30 months) male and female mice were given a moderate spinal contusion injury (T9–T10), and recovery was assessed for 28 days (BMS, rearing counts, distance traveled). Tibial trabecular bone volume was measured after 28 days with ex vivo microCT. While BMS scores did not differ across groups, older subjects travelled less in the open field and there was a decrease in rearing with age and SCI. As expected, aging decreased trabecular bone volume and cortical thickness in both old male and female mice. SCI alone also reduced trabecular bone volume in young mice, but did not have an additional effect beyond the age-dependent decrease in trabecular and cortical bone volume seen in both sexes. Interestingly, both rearing and total activity correlated with decreased bone volume. These data underscore the importance of load and use on bone mass. While partial weight-bearing does not stabilize/reverse bone loss in humans, our data suggest that therapies that simulate complete loading may be effective after SCI.

Abstract
The number of studies illuminating major sex differences in liver metabolic activities is growing, but we still lack a theory to explain the origin of the functional differences we are identifying. In the animal kingdom, energy metabolism is tightly associated with reproduction; conceivably, the major evolutionary step that occurred about 200 million years ago with placentation determined a significant change in female physiology, as females had to create new energy strategies to allow the growth of the embryo in the womb and the lactation of the newborn. In vertebrates the liver is the metabolic organ most tuned to gonadal functions because the liver synthesizes and transports of all the components necessary for the maturation of the egg upon estrogenic stimulation. Thus, in mammals, evolution must have worked on the already strict gonad-liver relationship fostering these novel reproductive needs. As a consequence, the functions of mammalian liver in females diverged from that in males to acquire the flexibility necessary to tailor metabolism according to reproductive status and to ensure the parsimonious exploitation and storage of energy for the continuation of gestation in case of food scarcity. Indeed, several studies show that male and female livers adopt very different strategies when confronted with nutritional stress of varied origins. Considering the role of liver and energy metabolism in most pathologies, a better focus on liver functions in the 2 sexes might be of considerable help in personalizing medicine and pharmacology for male and female needs.

Fractures in untreated patients with osteoporosis in Germany: an InGef healthcare insurance database analysis. Osteoporos Int 2022; 33:77-86. [PMID: 34268605 DOI: 10.1007/s00198-021-06051-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2020] [Accepted: 06/24/2021] [Indexed: 10/20/2022]
Abstract
UNLABELLED Osteoporosis is a skeletal disease that may result in low-trauma fracture if untreated. Among men and women ≥ 70 years untreated for osteoporosis, 30% (43,514) sustained at least one post-index fracture. Care for patients with osteoporosis diagnosis directly contributed to a cost burden of €786 million. INTRODUCTION Osteoporosis is a skeletal disease that manifests as bone mineral density loss and low-trauma fractures. This database analysis describes the characteristics of untreated osteoporosis patients, and their rate of fractures, health resource utilization, and cost burden. METHODS From the InGef database (2011-2016), eligible patients (≥ 70 years) untreated for osteoporosis were identified via a recorded diagnosis of osteoporosis (ICD-10 codes M80/M81) or an initial fragility fracture (index point). All patients were followed up for fractures post index. Direct costs included inpatient, outpatient, pharmacy, and ancillary care costs. RESULTS A total of 144,752 patients (mean age 79 years; 73% female, median follow-up of 3.2 years) met the eligibility criteria; 23% had a history of fractures. Forty-eight percent of patients had cardiac diseases, 32% diabetes, and 27% cerebrovascular disease. Thirty percent (43,514) of patients had at least one post-index fracture; two or more post-index fractures were experienced in 7% (10,262) of patients. Median time from index date to first fracture was 145.5 days. Bisphosphonates were the most prescribed osteoporosis treatment following a first fracture post-index (n = 4102, 9.2%). There was a total of 107,055 patients (74.0%) who had at least one all-cause hospital stay. The total number of fracture-related admissions was 63,595 and that of outpatient visits was 323,460. A total of 34,764 (24%) patients died during follow-up. Costs for fracture-related care for patients directly contributed to a cost burden of €786 million. CONCLUSIONS Osteoporosis patients and patients who sustain a fragility fracture remain undertreated for osteoporosis, increasing their risk of future fractures. Diagnosing and treating this group of patients should remain a priority to alleviate the clinical and economic burden of osteoporosis-related fractures.

[PMID: 34666201 DOI: 10.1016/j.bone.2021.116233] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 09/21/2021] [Accepted: 10/12/2021] [Indexed: 01/15/2023]
Abstract
BACKGROUND Magnesium plays a key role in bone health and may, therefore, represent an interesting nutrient for the prevention of bone loss and osteoporosis. The aim of this systematic review and meta-analysis was to investigate the impact of magnesium intake from any source on bone mineral density (BMD), bone mineral content (BMC), bone turnover markers, and fracture risk in older adults. METHODS A systematic search was conducted using Embase, Medline Ovid and Cochrane Central from database inception to October 2020. All studies that related magnesium intake with bone health outcomes among adults aged ≥60 years were included. Two investigators independently conducted abstract and full-text screenings, data extractions, and risk of bias assessments. Authors were contacted for missing data. RESULTS Once 787 records were screened, six cohort studies, one case-control study and five cross-sectional studies were included. Qualitative evaluation demonstrated a positive trend between higher magnesium intake and higher hip and femoral neck BMD. Meta-analysis of four studies showed a significant positive association between magnesium intake and hip BMD (pooled beta: 0.03, 95% CI: 0.01-0.06, p < 0.05). CONCLUSIONS This systematic review indicates that a higher magnesium intake may support an increase in hip and femoral neck BMD. Due to limited research no associations with BMD at other sites or fractures were found. There is a need for properly designed cohort studies to determine the association between magnesium intake and bone health in older adults. Next, large and long-term randomized controlled trials in older adults are needed to determine whether an increase in magnesium (supplementation) intake can improve bone health. The combination of several bone nutrients (calcium, vitamin D, protein, magnesium and potentially more) may be needed for the most optimal effect on bone health and to delay or prevent the development of osteoporosis.

Abstract
Although observational studies have explored factors that may be associated with osteoporosis, it is not clear whether they are causal. Osteoporosis in men is often underestimated. This study aimed to identify the causal risk factors associated with bone mineral density(BMD) in men. Single nucleotide polymorphisms (SNPs) associated with the exposures at the genome-wide significance (p < 5x10-8) level were obtained from corresponding genome-wide association studies (GWASs) and were utilized as instrumental variables. Summary-level statistical data for BMD were obtained from two large-scale UK Biobank GWASs. A Mendelian randomization (MR) analysis was performed to identify causal risk factors for BMD. Regarding the BMD of the heel bone, the odds of BMD increased per 1-SD increase of free testosterone (FT) (OR = 1.13, P = 9.4 × 10-17), together with estradiol (E2) (OR = 2.51, P = 2.3 × 10-4). The odds of BMD also increased with the lowering of sex-hormone binding globulin (SHBG) (OR = 0.87, P = 7.4 × 10-8) and total testosterone (TT) (OR = 0.96, P = 3.2 × 10-2) levels. Regarding the BMD of the lumbar spine, the odds of BMD increased per 1-SD increase in FT (OR = 1.18, P = 4.0 × 10-3). Regarding the BMD of the forearm bone, the odds of BMD increased with lowering SHBG (OR = 0.75, P = 3.0 × 10-3) and TT (OR = 0.85, P = 3.0 × 10-3) levels. Our MR study corroborated certain causal relationships and provided genetic evidence among sex hormone traits, lifestyle factors and BMD. Furthermore, it is a novel insight that TT was defined as a disadvantage for osteoporosis in male European populations.

Abstract
Carbon materials constitute a growing family of high-performance materials immersed in ongoing scientific technological revolutions. Their biochemical properties are interesting for a wide set of healthcare applications and their biomechanical performance, which can be modulated to mimic most human tissues, make them remarkable candidates for tissue repair and regeneration, especially for articular problems and osteochondral defects involving diverse tissues with very different morphologies and properties. However, more systematic approaches to the engineering design of carbon-based cell niches and scaffolds are needed and relevant challenges should still be overcome through extensive and collaborative research. In consequence, this study presents a comprehensive description of carbon materials and an explanation of their benefits for regenerative medicine, focusing on their rising impact in the area of osteochondral and articular repair and regeneration. Once the state-of-the-art is illustrated, innovative design and fabrication strategies for artificially recreating the cellular microenvironment within complex articular structures are discussed. Together with these modern design and fabrication approaches, current challenges, and research trends for reaching patients and creating social and economic impacts are examined. In a closing perspective, the engineering of living carbon materials is also presented for the first time and the related fundamental breakthroughs ahead are clarified.

Abstract
Type 1 diabetes (T1D)-induced osteoporosis is characterized by decreased bone mineral density, bone quality, rate of bone healing, bone formation, and increased bone resorption. Patients with T1D have a 2-7-fold higher risk of osteoporotic fracture. The mechanisms leading to increased risk of osteoporotic fracture in T1D include insulin deficiency, hyperglycemia, insulin resistance, lower insulin-like growth factor-1, hyperglycemia-induced oxidative stress, and inflammation. In addition, a higher probability of falling, kidney dysfunction, weakened vision, and neuropathy indirectly increase the risk of osteoporotic fracture in T1D patients. Decreased nitric oxide (NO) bioavailability contributes to the pathophysiology of T1D-induced osteoporotic fracture. This review discusses the role of NO in osteoblast-mediated bone formation and osteoclast-mediated bone resorption in T1D. In addition, the mechanisms involved in reduced NO bioavailability and activity in type 1 diabetic bones as well as NO-based therapy for T1D-induced osteoporosis are summarized. Available data indicates that lower NO bioavailability in diabetic bones is due to disruption of phosphatidylinositol 3‑kinase/protein kinase B/endothelial NO synthases and NO/cyclic guanosine monophosphate/protein kinase G signaling pathways. Thus, NO bioavailability may be boosted directly or indirectly by NO donors. As NO donors with NO-like effects in the bone, inorganic nitrate and nitrite can potentially be used as novel therapeutic agents for T1D-induced osteoporosis. Inorganic nitrites and nitrates can decrease the risk for osteoporotic fracture probably directly by decreasing osteoclast activity, decreasing fat accumulation in the marrow cavity, increasing osteoblast activity, and increasing bone perfusion or indirectly, by improving hyperglycemia, insulin resistance, and reducing body weight.

Abstract
Background: The effect of aqua training on human body composition still causes inconsistency. Objectives: This study was set to identify the effects of WATERinMOTION (WiM) as a water-based exercise on anthropometric and body composition variables without dietetic supervision in overweight/obese, sedentary elderly men. Methods: Participants (n = 70; age: 70.5 ± 4.4 years) derived by purposive and accessible selection were randomly distributed to either a one-month WiM aqua training group (n = 35, two weekly sessions each included 55 minutes on WiM aqua training) or a control group (n = 35, at the same time in sitting state). Anthropometric measures (height, weight, and waist circumference [WC]) and body composition variables (body mass index [BMI], fat mass [FM], total body water [TBW], and free fat mass [FFM]) were evaluated pre/post-study. Results: Upon analysis, statistically significant changes (P ≤ 0.05) were set on weight, BMI, and FM by comparing pre/post study for the WiM group. Furthermore, comparing groups at post disclosed a significant change in anthropometric measures (weight and WC) and body composition variables (BMI, FM, TBW, and FFM). Conclusions: A short-run, non-diet-supervised WiM program suggests supporting a loss in weight, FM, and BMI in overweight/obese, sedentary elderly men.

Abstract
BACKGROUND Osteoporosis is one of the most common bone system diseases that is associated with an increased risk of bone fractures and causes many complications for patients. With age, the prevalence of this disease increases so that it has become a serious problem among the elders. In this study, the prevalence of osteoporosis among elders around the world is examined to gain an understanding of its prevalence pattern. METHODS In this systematic review and meta-analysis, articles that have focused on prevalence of osteoporosis in the world's elders were searched with these key words, such as Prevalence, Osteoporosis, Elders, Older adult in the Science Direct, Embase, Scopus, PubMed, Web of Science (WoS) databases and Google Scholar search engine, and extracted without time limit until March 2020 and transferred to information management software (EndNote). Then, duplicate studies were eliminated and the remaining studies were evaluated in terms of screening, competence and qualitative evaluation based on inclusion and exclusion criteria. Data analysis was performed with Comprehensive Meta-Analysis software (Version 2) and Begg and Mazumdar test was used to check the publication bias and I2 test was used to check the heterogeneity. RESULTS In a review of 40 studies (31 studies related to Asia, 5 studies related to Europe and 4 studies related to America) with a total sample size of 79,127 people, the prevalence of osteoporosis in the elders of the world; 21.7% (95% confidence interval: 18.8-25%) and the overall prevalence of osteoporosis in older men and women in the world, 35.3% (95% confidence interval: 27.9-43.4%), 12.5% (95% confidence interval: 9.3-16.7%) was reported. Also, the highest prevalence of osteoporosis in the elders was reported in Asia with; 24.3% (95% confidence interval: 20.9-28.1%). CONCLUSION The results of the present study showed that the prevalence of osteoporosis in the elders and especially elders' women is very high. Osteoporosis was once thought to be an inseparable part of elders' lives. Nowadays, Osteoporosis can be prevented due to significant scientific advances in its causes, diagnosis, and treatment. Regarding the growing number of elderly people in the world, it is necessary for health policy-makers to think of measures to prevent and treat osteoporosis among the elders.

Abstract
Background It has been reported that serum periostin levels are significantly higher in postmenopausal patients with osteoporotic fractures. Nonetheless, the levels of serum periostin in postmenopausal women with different bone mass remain unclear. Purpose The objective of the study was to identify the levels of serum periostin in Chinese postmenopausal women with different bone mass, and the correlations between the periostin levels and the classical bone turnover markers (BTMs), and bone mineral densities (BMDs) at different sites. Patients and Methods This study enrolled 331 Chinese postmenopausal women in Shanghai; their clinical features were collected; their levels of serum periostin and traditional BTMs were measured by ELISA or the fully automated immunoassay analyzer; their BMDs at different sites were measured by dual-energy X-ray absorptiometry (DXA). Results According to the T-value of bone mineral density (BMD), these postmenopausal women were divided into normal group (n=84), osteopenia group (n=126) and osteoporosis group (n=121). There was no significant difference in the serum periostin levels among the above three groups of subjects. In addition, Spearman correlation analysis also revealed that no correlation was observed between the value of serum periostin and those of traditional BTMs, and BMDs at different sites, respectively. The values of traditional BTMs were negatively correlated with those of BMDs at all measured sites. Furthermore, the receiver-operating characteristic (ROC) curves analysis indicated that among the periostin and traditional BTMs mentioned above, the best predictors for postmenopausal osteoporosis in Shanghai Chinese postmenopausal women were osteocalcin (OC) and procollagen type 1 N-terminal propeptide (P1NP) [the areas under the ROC curve (AUC)=0.746 and 0.761, respectively]. Conclusion Serum periostin may not be used as a marker of systemic bone metabolism in Shanghai Chinese postmenopausal women without prior fracture. In addition, serum P1NP and OC levels may be the predictors of osteoporosis occurrence in Chinese postmenopausal women.

Abstract
Background Adequate footwear comfort and functionality are important regardless of age, but they become particularly important in the youngest-old women and men, mainly due to the fact that this age range is the initial period of old age with changes in shoe preferences. The aim of this study was to assess the perception of footwear comfort and its relationship with the feet structure in youngest-old women and men. Methods The cross-sectional study covered community dwellers living on their own aged 65–74 years (50 women; 50 men). The feet characteristics were measured using the CQ-ST podoscope (Electronic System, Ltd, EU), and the perception of footwear comfort was assessed with a visual analogue scale. The assessment took into account gender-specific footwear of a certain brand (Befado Dr orto). Results Statistically significant intergender differences were observed in the perception of footwear comfort with respect to the shoe heel width (p = 0.022), the arch height (p = 0.013), the overall comfort (p = 0.049) and the material properties of the footwear (p = 0.017). In women, there were statistically significant positive relationships among the heel angle (γ) and the perception of footwear comfort in terms of heel cushioning (p = 0.021), forefoot cushioning (p = 0.015), arch height (p = 0.029). In men, there was a statistically significant negative relationship of the left foot Clarke’s angle with the heel height (p = 0.043), and a positive relationship between the right foot width and the arch height (p = 0.044). Conclusions Youngest-old women, compared to men of the same age range, have a higher perception of shoe comfort in terms of the shoe heel width, the arch height, the overall comfort of the footwear and the material properties of the footwear. The appropriate profile and construction of the shoe allows for an increase in the contact surface of the foot with the shoe, hence the improvement in the perception of footwear comfort in people with lowered arch or widened forefoot.

Abstract
OBJECTIVE To assess how bone morphology and mineralization changes with age, in women by digital X-ray radiogrammetry (DXR). DXR has potential as a screening tool for osteoporosis, as it can evaluate bone mineralization similarly to dual-energy X-ray absorptiometry. METHODS The nondominant hand was analyzed with DXR in 13,285 women ages 40-74 years undergoing mammography. 1,556 women attended two consecutive examinations with 18 to 24 months interval. Changes in bone parameters were calculated and compared in 5-year age groups. Regression analysis and ANOVA tests were performed. RESULTS Univariate linear regression showed no significant difference in age or bone size between the groups with single or consecutive measurements. In the group with consecutive measurements, the average inner diameter (DXR-ID) of the metacarpals significantly increased with age from 0.38 cm in the 40-45 years age span to 0.47 cm in the 65+ age group (P < 0.001), whereas DXR bone mineral density (DXR-BMD) decreased from 0.59 g/cm2 to 0.50 g/cm2 in the same age groups (P < 0.001). Intraindividual measurements showed a fourfold increase in yearly DXR-ID increase and concurrent DXR-BMD loss between 50 and 59 years of age (P < 0.001). The outer diameter only increased significantly between the youngest and oldest age group (P < 0.001). CONCLUSIONS The faster decrease in DXR-BMD observed during and after menopause is caused by resorption of the inner cortical surface, not matched by outer diameter increase. We speculate that most bones in the human body grow in the same pattern as observed in the metacarpals, partly explaining decreasing BMD at DXR and dual-energy X-ray absorptiometry.

Abstract
INTRODUCTION As the elderly population of the United States and the world increases, so does the incidence of osteoporotic fragility fractures from a fall or minor injury. This results in a large cost to the health care system. This cost is further increased as more than 50% of individuals will have refractures within the first year. In order to reduce the refracture rate in such patients, we enrolled our elderly trauma patients with vertebral compression fractures and vertebral augmentation in a Fracture Liaison Service (FLS) clinic for two years and reevaluated their refracture rate. METHOD This is a retrospective analysis of 720 patients. 142 patients (Group A) were seen between 2012 and 2014 before establishing the FLS program and 578 patients (Group B) were seen between 2015 and 2020 after implementation of the FLS program. The patients enrolled in the FLS program were followed for two years after sustaining a vertebral compression fracture. The data collected included age, sex, serum calcium and vitamin D levels, dual energy X-ray absorptiometry (DXA) scan, 10-year fracture risk (FRAX) score, pressure measurements in PSI taken during vertebral augmentation, as well as the refracture rate. The data collected were analyzed and compared between the two groups using the Student's t-test and chi-square test. RESULTS There was significant reduction in the refracture rate of pre-FLS vs post-FLS vertebral, as well as other fractures in the FLS group (pre-FLS: 48.9% vs post-FLS: 37.0%; P = .01). There was no significant difference between groups A and B in regard to the mean serum level of calcium (9.44 mg/dL vs 9.53 mg/dL), vitamin D level (35.04 ng/mL vs 41.39 ng/mL), DXA scan for spine (-.52 vs -.76) and for femur (-1.77 vs -1.52), and 10-year refracture risk for osteoporotic major fracture (FRAX score-mean: 22.6% vs 19.2%) and for hip fracture (9.18% vs 7.53%). There was a significant difference in the mean age between the groups (79.5 vs 73.5 years; P = .01). Of those who underwent vertebral augmentation, 235 had Pressure Scale Index (PSI) measurements taken. There was a trend in increasing refracture rate when PSI ≤199 compared with those who had PSI ≥200, although statistical significance was not met (33.9% vs 27.0%, P = .21). CONCLUSION A Fracture Liaison Service program will improve the bone health of geriatric osteoporotic patients presenting to the trauma service with vertebral compression fractures and thus reduces the subsequent refracture rate. Further study is needed to evaluate the best PSI used to impact reduction in refracture rate.

Gender, health and ageing in Fiji: a mixed methods analysis. Int J Equity Health 2021; 20:205. [PMID: 34521430 PMCID: PMC8439064 DOI: 10.1186/s12939-021-01529-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Accepted: 08/10/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Women are disadvantaged by ageing: older women are more likely than older men to suffer from ill-health, have less access to health care and suffer discrimination within the health care system. Globally, there is a dearth of health research on gender and ageing with substantial knowledge gaps in low and middle-income country contexts. Part of a wider investigation on health and ageing in Fiji, our objective was to identify and describe gendered differences in healthy ageing in this Pacific Island context. We believe this to be the first such study in the Pacific region. METHODS Applying a health systems lens, we used a mixed-methods approach, encompassing analysis of cause of death data; focus group discussion to gather community and family attitudes to health services; and policy analysis, and then used data triangulation techniques to draw out key themes and insights. RESULTS We found that gender affects health outcomes among older persons, attitudes towards and experience of healthy ageing, and an older person's access to and use of health services. We also found that while Fiji's policy response to ageing has recognised the importance of gender, to-date there has been limited action to address gender differences. Gender (as oppose to sex differences) has direct and indirect implications for the health of older Fijians, while gendered inequalities and patriarchal norms appear to affect both men and women's experience of ageing and the health system response. Further, gender and age discrimination may be intersecting, intensifying their separate effects. CONCLUSION This study demonstrates the feasibility and importance of applying a gender lens to the study of healthy ageing. Our findings from Fiji may be relevant to other island nations in the south Pacific which share similar challenges of population ageing, a constrained health budget and geographically-dispersed populations. The data triangulation methodology may be considered an efficient and insightful way to examine gendered responses to healthy ageing elsewhere.

Bone mineral density and risk of cardiovascular disease in men and women: the HUNT study. Eur J Epidemiol 2021; 36:1169-1177. [PMID: 34515906 PMCID: PMC8629874 DOI: 10.1007/s10654-021-00803-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Accepted: 08/30/2021] [Indexed: 11/17/2022]
Abstract
The association between bone mineral density (BMD) and cardiovascular disease (CVD) is not fully understood. We evaluated BMD as a risk factor for cardiovascular disease and specifically atrial fibrillation (AF), acute myocardial infarction (AMI), ischemic (IS) and hemorrhagic stroke (HS) and heart failure (HF) in men and women. This prospective population cohort utilized data on 22 857 adults from the second and third surveys of the HUNT Study in Norway free from CVD at baseline. BMD was measured using single and dual-energy X-ray absorptiometry in the non-dominant distal forearm and T-score was calculated. Hazard ratios (HR) and 95% confidence intervals (CI) were calculated from adjusted cox proportional hazards models. The analyses were sex-stratified, and models were adjusted for age, age-squared, BMI, physical activity, smoking status, alcohol use, and education level. Additionally, in women, we adjusted for estrogen use and postmenopause. During a mean follow-up of 13.6 ± 5.7 years, 2 928 individuals (12.8%) developed fatal or non-fatal CVD, 1 020 AF (4.5%), 1 172 AMI (5.1%), 1 389 IS (6.1%), 264 HS (1.1%), and 464 HF (2.0%). For every 1 unit decrease in BMD T-score the HR for any CVD was 1.01 (95% CI 0.98 to 1.04) in women and 0.99 (95% CI 0.94 to 1.03) in men. Point estimates for the four cardiovascular outcomes ranged from slightly protective (HR 0.95 for AF in men) to slightly deleterious (HR 1.12 for HS in men). We found no evidence of association of lower distal forearm BMD with CVD, AF, AMI, IS, HS, and HF.

Abstract
BACKGROUNDS/AIMS This study was performed to reveal the usefulness of the trabecular bone score (TBS) in assessing bone strength in patients with ankylosing spondylitis (AS) in comparison with dual-energy X-ray absorptiometry (DXA) methods. METHODS A total of 215 AS patients (75.8% male) were enrolled from a single university hospital in Korea. Demographic and clinical information were assessed. Patients completed X-rays of the cervical and lumbar spine (L-spine), and spinal ankyloses were quantified using the modified Stoke AS Spine Score (mSASSS). Hip, anteroposterior and lateral L-spine bone mineral density (BMD) and TBS were assessed by DXA methods. Clinical characteristics and bone strength measurement results were compared between male and female AS patients. The accuracy of each bone strength evaluation method in predicting Fracture Risk Assessment Tool (FRAX) scores indicating moderate or higher fracture risk was compared by receiver operating characteristic curves in patients aged ≥ 40 years. Correlations between each bone strength measurement method and mSASSS were examined. RESULTS Male patients showed higher mSASSS and less prevalent peripheral joint involvement compared to female patients (p < 0.05). TBS, hip BMD, and L-spine lateral BMD showed comparably high areas under the curve (AUCs) for predicting FRAX-major osteoporotic fractures (MOF) ≥ 10% (AUC ranged 0.72 to 0.76). TBS negatively correlated with mSASSS in both male and female patients (p < 0.01). CONCLUSION TBS could predict the risk of MOF and is not influenced by spinal osteoproliferation in AS patients, even in those with advanced spinal changes.

Abstract
Objective Hemorrhagic transformation (HT) can be occurred after acute cerebral infarction. HT can worse symptoms in severe cases and adversely affect long-term prognosis. As bone and vascular smooth muscle are composed of type 1 collagen, we aimed to identify a potential relationship between bone mineral density (BMD) and HT after acute cardioembolic stroke.
Methods As an indicator of BMD, we used mean frontal skull Hounsfield unit (HU) values on brain computed tomography (CT). Multivariative hazard ratios were calculated using Cox regression analysis to identify whether the osteoporotic condition was an independent predictor of HT after acute cardioembolic stroke.
Results This 11-year analysis enrolled 506 patients who diagnosed as acute cardioembolic infarction. The first tertile of skull HU value was an independent predictor of HT development compared to the third tertile (hazard ratio, 2.12; 95% confidence interval, 1.13–3.98; p=0.020). We observed no interactions between age and skull HU with respect to HT statistically.
Conclusion The results of this study revealed an association between osteoporotic conditions and HT development after acute cardioembolic stroke. A convenient method to measure the cancellous bone HU value of the frontal skull using brain CT images may be useful for predicting HT in patients with acute cerebral infarction.

Abstract
UNLABELLED Osteoporosis-related fragility fractures increase the risk of subsequent fractures and are associated with substantial morbidity and mortality. Emphasis should be placed on the prevention of recurrent fractures, which will decrease both the clinical burden on patients and the economic burden on the health system. INTRODUCTION Fragility fractures are associated with increased morbidity and mortality. Quantifying the clinical and economic burden of subsequent fractures following an initial osteoporosis-related fracture is a key to informing public health policies. METHODS A retrospective cohort study, using the national French health insurance claims database. Males and females ≥ 50 years, with a hospital discharge diagnosis of osteoporosis with fracture or a relevant fragility fracture (hip, vertebrae, femur, pelvis, wrist/hand, forearm, humerus/clavicle) between 2011 and 2014, were included and followed until death or end of 2016, whichever came first. Index fracture was the first qualifying hospitalization; subsequent fractures were defined as those occurring either at a different site from the index fracture or at the same site ≥ 90 days apart. Costs abstracted included hospitalization, external consultation, outpatient visits, and treatment. RESULTS A total of 544,426 participants (132,148 [24.3%] males and 412,278 [75.7%] females), of whom 16,110 (12.2%) males and 73,538 (17.8%) females had at least one subsequent fracture during follow-up, were included. Incidence of subsequent fracture was highest in the first year following index fracture. During follow-up, 161,179 patients died; mortality was highest among those with a hip fracture at index (29,971 (51.6%) males and 65,254 (39.6%) females). Total mean costs per patient in the year following index fracture were highest for males and females with a hip fracture (€18,585 and €15,754, respectively). CONCLUSION Subsequent fractures among osteoporotic participants with an initial fracture result in increased clinical mortality and high healthcare resource use. Emphasis should be placed on the prevention of recurrent fractures.

Abstract
Due to improvements in diabetes care, people with type 1 diabetes (T1D) are living longer. Studies show that post-menopausal T1D women have a substantially elevated cardiovascular risk compared to those without T1D. As T1D may also accelerate age-related bone and muscle loss, the risk of frailty may be considerable for T1D women. Exercise and physical activity may be optimal preventative therapies to maintain health and prevent complications in this population: They are associated with improvements in, or maintenance of, cardiovascular health, bone mineral density, and muscle mass in older adults. Resistance exercise, in particular, may provide important protection against age-related frailty, due to its specific effects on bone and muscle. Fear of hypoglycemia can be a barrier to exercise in those with T1D, and resistance exercise may cause less hypoglycemia than aerobic exercise. There are currently no exercise studies involving older, post-menopausal women with T1D. As such, it is unknown whether current guidelines for insulin adjustment/carbohydrate intake for activity are appropriate for this population. This review focuses on existing knowledge about exercise in older adults and considers potential future directions around resistance exercise as a therapeutic intervention for post-menopausal T1D women.

Abstract
CONTEXT Acromegaly can impair bone integrity, increasing the risk of vertebral fractures (VFs). OBJECTIVE To evaluate the impact of isolated GH/IGF-I hypersecretion on bone turnover markers, Wnt inhibitors, bone mineral density (BMD), microarchitecture, bone strength and vertebral fractures in female patients with acromegaly (Acro), compared with healthy control group (HC). DESIGN, SETTING, AND PATIENTS Cross-sectional study including 83 premenopausal women without any pituitary deficiency:18 acromegaly in remission (AcroR), 12 in group with active acromegaly (AcroA), and 53 HC. Serum procollagen type 1 N-terminal propeptide, β-carboxy-terminal crosslinked telopeptide of type 1 collagen, osteocalcin, sclerostin, and DKK1 were measured in blood samples. dual-energy X-ray absorptiometry, high-resolution peripheral quantitative computed tomography (HR-pQCT) and vertebral fractures evaluation were also assessed simultaneously. MAIN OUTCOME AND RESULTS AcroA showed significantly lower sclerostin and higher DKK1 compared with HC. On HR-pQCT of tibia and radius, Acro showed impairment of trabecular (area and trabecular number), increased cortical porosity, and increased cortical area and cortical thickness compared with HC. The only significant correlation found with HR-pQCT parameters was a positive correlation between cortical porosity and serum DKK1 (R = 0.45, P = 0.044). Mild VFs were present in approximately 30% of patients. CONCLUSIONS Eugonadal women with acromegaly without any pituitary deficiency showed increased cortical BMD, impairment of trabecular bone microstructure, and increased VF. Sclerostin was not correlated with any HR-pQCT parameters; however, DKK1 was correlated with cortical porosity in tibia (P = 0.027). Additional studies are needed to clarify the role of Wnt inhibitors on bone microarchitecture impairment in acromegaly.

The Gender-Specific Relationship between Nutritional Status, Physical Activity and Functional Mobility in Irish Community-Dwelling Older Adults. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18168427.

Abstract
Research suggests that both nutrition and physical activity can protect mobility in older adults, but it is yet to be determined whether these relationships are affected by gender. Thus, we investigated the gender-specific relationship between nutritional status, physical activity level and functional mobility in Irish older adults. A cross-sectional study was undertaken in 176 community-dwelling older adults (73.6 ± 6.61 years) living in Cork, Ireland. Nutritional status was measured using the Mini Nutritional Assessment-Short Form (MNA-SF) and physical activity was assessed via the Physical Activity Scale for the Elderly (PASE). Functional mobility was measured using the Timed Up and Go (TUG) test. The gender-stratified relationship between variables was assessed using Pearson's correlations and multiple linear regression. Partial correlations (p < 0.05) were observed for TUG with PASE score in both genders, and with MNA-SF score in females, only. Multiple regression showed that physical activity was a predictor of TUG in both genders (β = 0.257 for males, β = 0.209 for females, p < 0.05), while nutritional status was a predictor of TUG in females, only (β = -0.168, p = 0.030). Our results suggest that physical activity is associated with functional mobility in both genders, while the relationship between nutritional status and mobility may be specific to older females. These findings may be of interest for the design of functional preservation strategies.

Salicylic acid-based nanomedicine with self-immunomodulatory activity facilitates microRNA therapy for metabolic skeletal disorders. Acta Biomater 2021; 130:435-446. [PMID: 34089908 DOI: 10.1016/j.actbio.2021.05.024] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2021] [Revised: 05/20/2021] [Accepted: 05/26/2021] [Indexed: 12/22/2022]
Abstract
Metabolic skeletal disorders remain a major clinical challenge. The complexity of this disease requires a strategy to address the net effects of both inflammation and impaired bone formation. microRNA-based gene therapy provides several therapeutic advantages to tackle these issues. Herein, we describe a microRNA-21 (miR-21) delivery system with an additional therapeutic effect from that of the delivery carrier itself. Poly (salicylic acid) (PSA) is, for the first time, synthesized via polycondensation of salicylic acid (SA), a bioactive ingredient widely used for anti-inflammation in medicine. PSA can self-assemble into nanoparticles (PSA-NPs) and can effectively deliver genes both in vitro and in vivo. The carrier was then attached to repetitive sequences of aspartate, serine, serine (DSS)6 for delivering miRNAs specifically to bone-formation surfaces. In vitro studies showed that miR-21@PSA-NP could effectively realize the intracellular delivery of miR-21 with low toxicity, while in vivo results indicated that the miR-21@PSA-NP-DSS6 prolonged blood circulation time, enhanced bone accumulation, and significantly improved the efficacy of miR-21-based bone anabolic therapy in osteoporotic mice. The constructed delivery system (miR-21@PSA-NP-DSS6) inherited the advantages of both SA and miR-21, which could ameliorate bone-inflamed niche and rescued the impaired bone formation ability. The synergy of anti-inflammatory and pro-osteogenic effects significantly improved trabecular bone microstructure in osteoporotic mice. STATEMENT OF SIGNIFICANCE: The complexity of metabolic skeletal disorders requires a strategy to address the net effects of both inflammation and impaired bone formation. microRNA-based gene therapy provides several therapeutic advantages to tackle these issues. We develop a novel microRNA-21 delivery system with additional therapeutic effect from that of the gene carrier itself. Poly (salicylic acid) (PSA) nanoparticles, for the first time, synthesized via polycondensation of salicylic acid and can effectively deliver genes both in vitro and in vivo. The constructed delivery system (miR-21@PSA-NP-DSS6) inherited the advantages of both SA (commonly used anti-inflammation drug in medicine) and miR-21 (a pro-osteogenic molecule), which could ameliorate bone-inflamed niche, rescued impaired bone formation ability and significantly improved trabecular bone microstructure in osteoporotic mice.

Pharmacogenomic Effects of β-Blocker Use on Femoral Neck Bone Mineral Density. J Endocr Soc 2021; 5:bvab092.

Abstract
CONTEXT Recent studies have shown that β-blocker (BB) users have a decreased risk of fracture and higher bone mineral density (BMD) compared to nonusers, likely due to the suppression of adrenergic signaling in osteoblasts, leading to increased BMD. There is also variability in the effect size of BB use on BMD in humans, which may be due to pharmacogenomic effects. OBJECTIVE To investigate potential single-nucleotide variations (SNVs) associated with the effect of BB use on femoral neck BMD, we performed a cross-sectional analysis using clinical data, dual-energy x-ray absorptiometry, and genetic data from the Framingham Heart Study's (FHS) Offspring Cohort. We then sought to validate our top 4 genetic findings using data from the Rotterdam Study, the BPROOF Study, the Malta Osteoporosis Fracture Study (MOFS), and the Hertfordshire Cohort Study. METHODS We used sex-stratified linear mixed models to determine SNVs that had a significant interaction effect with BB use on femoral neck (FN) BMD across 11 gene regions. We also evaluated the association of our top SNVs from the FHS with microRNA (miRNA) expression in blood and identified potential miRNA-mediated mechanisms by which these SNVs may affect FN BMD. RESULTS One variation (rs11124190 in HDAC4) was validated in females using data from the Rotterdam Study, while another (rs12414657 in ADRB1) was validated in females using data from the MOFS. We performed an exploratory meta-analysis of all 5 studies for these variations, which further validated our findings. CONCLUSION This analysis provides a starting point for investigating the pharmacogenomic effects of BB use on BMD measures.

Abstract
OBJECTIVE The aim of this study is to explore the current characteristics of people with chronic lower back (CLB) pain, and the sociodemographic and work-related predictors of this pain. STUDY DESIGN The study design used in the study is a cross-sectional study. METHOD The 2018 National Health Interview Survey data were used. Chi-squared analysis was used to assess the sociodemographic characteristics, and logistic regression was used to analyze the risk factors after multiple imputation. RESULTS Of the 72,831 respondents, 25,397 had provided data on CLB pain and were eligible for this study. People with CLB pain were more likely to be obese, white, female, older than 40 years, and did not have a college degree. They were more likely to carry out less than 150 min of moderate aerobic exercise per week. Age was the sociodemographic predictor of CLB pain (P-value <0.001). After imputation and adjusting for covariates, construction and extraction and military-specific occupational groups were associated with an increased risk of CLB pain [odds ratios (OR): 1.32, confidence interval (CI): 1.10-1.59, P-value = 0.004; OR: 2.20, CI: 1.36-3.55, P-value = 0.001]. Working between 41 and 60 h/week significantly also had an increased risk of developing CLB pain (OR: 1.13, CI: 1.01-1.27, P-value 0.043; OR: 1.23, CI: 1.10-1.37, P-value <0.001). CONCLUSION Low socio-economic status, poor physical fitness, work-life imbalance, and the type of occupation contribute to the development of CLB pain. An improvement in preventive measures is needed to address this morbidity. More studies should be carried out to analyze the type of workplace movements that increase the risk of developing CLB.

Abstract
Standards and models of reference for osteoporosis (OP) have been developed for female individuals as they are more likely to be affected by the disease. Nonetheless, OP is also responsible for one-third of hip fractures in male individuals suggesting that a sexblinded approach to OP may lead to miss opportunities for equity in bone health. OPrelated fractures, especially hip fractures, are a matter of immediate concern as they are associated with limited mobility, chronic disability, loss of independence, and reduced quality of life in both sexes. When it comes to sociocultural gender, the effect of gender domains (i.e., identity, roles, relations, and institutionalized gender) on development and management of OP is largely overlooked despite risk factors or protective conditions are gendered. Clinical trials testing the efficacy and safety of anti-OP drugs as well as non-pharmacological interventions have been conducted mainly in female participants, limiting the generalizability of the findings. The present narrative review deals with the sex and gender-based challenges and drawbacks in OP knowledge and translation to clinical practice, also considering the impact of coronavirus disease 2019 pandemic.

Abstract
OBJECTIVE To examine the contribution of skeletal mass index (SMI) as a mediator in the relationship between menarcheal age and hip/spine bone mineral density (BMD) in premenopausal women by race/ethnicity. METHODS The data of 4,329 participants (age ≥ 18; mean age=35.7 ± 9.5) of Whites (n = 2,543), African Americans (n = 1,236), and Asians (n = 550) enrolled from October 2011 to January 2019 from the Louisiana Osteoporosis Study were analyzed. After adjustment for physiological and behavioral factors, multivariable linear regression analyses were conducted to evaluate each component of the proposed mediation models, and mediation was verified by the bootstrapping resampling approach. RESULTS Premenopausal women with early menarcheal age tended to have higher SMI and BMD than women with normal menarcheal age among all races/ethnicities included. Women with late menarcheal age were, however, more likely to have a lower SMI than their counterparts with normal menarcheal age (r = -0.212, 95% CI = [-0.321 to -0.103] for White women; r = -0.181, 95% CI = [-0.410 to -0.008] for African-American women; r = -0.174, 95% CI = [-0.343 to -0.006] for Asian women). Similar results were found for both spine and hip BMD. SMI fully mediated the difference in BMD due to different menarcheal ages among Whites, African Americans, and Asian women with early menarcheal age; however, no mediating effects were observed for Asian women with late menarcheal age. CONCLUSIONS SMI, as a full mediator, affected the relationship between menarcheal age and BMD among premenopausal women, and the mediating effects varied by race/ethnicity. To prevent or slow down the loss of hip/spine BMD and the development of osteoporosis, measures aiming at minimizing the risk for muscle mass loss should be recommended, especially for White and African-American women with late menarcheal age.

Abstract
Background Milk consumption is associated with bone mineral density (BMD), but reports are limited in terms of participant age, sex, and number of study subjects. We investigated the association between milk consumption and BMD in South Korean adults (≥20 years). Methods We analyzed men and women aged ≥20 years who participated in the Korean National Health and Nutrition Examination Survey, 2008–2011. We used linear regression to calculate the mean BMD and 95% confidence interval (CI) based on the frequency of milk consumption. Multivariate logistic regression analysis was used to estimate the odds ratios (ORs) and 95% CI for T-scores ≤-2.5 (osteoporosis) in both men aged ≥50 years and postmenopausal women. Results In total 8,539 subjects were studied. Drinking milk more than once a day was associated with higher BMD in the total femur and femoral neck in men aged <50 years and lumbar spine in men aged ≥50 years, compared to less than once a week. It was also associated with lower ORs for osteoporosis of the femoral neck and lumbar spine in men aged ≥50 years (OR, 0.35; 95% CI, 0.125–0.979 and OR, 0.34; 95% CI, 0.143–0.804, respectively). In postmenopausal women who consumed milk 2–6 times weekly, higher BMD and lower OR for osteoporosis were observed in the total femur (OR, 0.23; 95% CI, 0.055–0.958). Conclusion This study suggests that frequent milk consumption could potentially reduce osteoporosis incidence in South Korean adults. Further prospective study is necessary to elucidate the effect of milk consumption on BMD.

Abstract
OBJECTIVE Osteoporosis is highly prevalent among patients with chronic obstructive pulmonary disease (COPD) and most commonly presents as a vertebral compression fracture (VCF). Our objective was to quantify the effect of osteoporosis and VCFs on the mortality and pulmonary function tests (PFTs), such as forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC), of patients with COPD. METHODS A PubMed/Medline search was conducted using the search terms "chronic obstructive pulmonary disease", "osteoporosis" and "vertebral compression fracture". Meta-analyses were conducted to evaluate the differences in mortality and PFTs between patients with COPD with and without osteoporosis or VCFs, according to PRISMA guidelines. PROSPERO registration: CRD42019120335. RESULTS Of the 896 abstracts identified, 27 studies describing 7662 patients with COPD of which 1883 (24.6%) had osteoporosis or VCFs, were included. Random effects model analysis demonstrated that patients with COPD and osteoporosis or VCFs had an increased OR for mortality of 2.40 (95% CI: 1.24; 4.64, I2=89%, P<0.01), decreased FEV1/FVC with a mean difference of -4.80% (95% CI: -6.69; -2.90, I2=83%, P<0.01) and decreased FEV1, with a mean difference of -4.91% (95% CI: -6.51; -3.31, I2=95%, P<0.01) and -0.41 L (95% CI: -0.59; -0.24, I2=97%, P<0.01), compared to control subjects. Apart from FEV1 (liters) in subgroup 1 (P=0.06), all subgroup analyses found significant differences between groups, as did sensitivity analysis of low risk of bias studies. CONCLUSION Osteoporosis and VCFs are associated with a significant reduction in survival and pulmonary function among patients with COPD.

Abstract
INTRODUCTION One in two women and one in four men experience an osteoporosis-related fracture in their lifetime. Related morbidity and mortality rates are higher in men versus women. Current guidelines are inconsistent in the screening recommendations for osteoporosis in men. Examination of gender disparities in the management of osteoporosis-related fractures among Medicare enrollees is currently lacking. METHODS In this retrospective cohort study using 5% National Medicare claims data from January 1, 2012 through December 31, 2016, eligible patients who were at least 65 years of age on the date of a new fracture episode were classified into two mutually exclusive cohorts on the basis of whether they received testing and/or treatment for osteoporosis in the 6-month period after the new fracture episode. The cohorts were defined on the basis of the National Committee for Quality Assurance (NCQA) quality measure "osteoporosis management in women who had a fracture." Patients were followed to identify the occurrence of subsequent fracture, all-cause mortality, and a composite outcome-defined as the first occurrence of either subsequent fracture or mortality. Logistic regression models were carried out to identify predictors of testing and/or treatment and time-varying survival analysis to identify the relationship between the presence of testing and/or treatment and patient outcomes. RESULTS Of the 35,774 eligible patients, only 10.2% (12.1% women and 5.7% men) received osteoporosis testing and/or treatment within 6 months after a fracture. The interaction between gender and fragility fracture was significant (P < 0.0001). Fragility fracture had greater adjusted odds of testing and/or treatment among men (adjusted odds ratio [AOR] 3.47; 95% CI 2.94-4.10) than women (AOR 1.65; 95% CI 1.53-1.79). Of patients who were eligible for the outcome assessment, 27.5% experienced a subsequent fracture, 23.2% died, and 44.3% experienced a composite outcome during follow-up. Patients who received testing and/or treatment had a significantly lower hazard of all-cause mortality (hazard ratio [HR] 0.57; 95% CI 0.50-0.65; P < 0.0001) and the composite outcome (HR 0.42; 95% CI 0.39-0.45; P < 0.0001), but no difference in the risk of subsequent fracture (HR 1.02; 95% CI 0.94-1.11; P = 0.6083). Men were found to have a significantly lower hazard of subsequent fracture (HR 0.69; 95% CI 0.64-0.73; P < 0.0001), all-cause mortality (HR 0.67; 95% CI 0.61-0.72; P < 0.0001), and the composite outcome (HR 0.69; 95% CI 0.65-0.73; P < 0.0001). CONCLUSION Testing and/or treatment for osteoporosis among older adults with a fracture is poor in the Medicare fee-for-service population overall and worse for men compared to women. Receiving appropriate testing and/or treatment was associated with reduced mortality and the risk of composite outcome. Improving osteoporosis testing and/or treatment and reducing health disparities are essential for managing the clinical and economic burden of osteoporosis in the USA.

Current Perspectives on the Beneficial Effects of Soybean Isoflavones and Their Metabolites for Humans. Antioxidants (Basel) 2021; 10:antiox10071064. [PMID: 34209224 PMCID: PMC8301030 DOI: 10.3390/antiox10071064] [Citation(s) in RCA: 97] [Impact Index Per Article: 32.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Revised: 06/27/2021] [Accepted: 06/28/2021] [Indexed: 12/13/2022] Open
Abstract
Soybeans are rich in proteins and lipids and have become a staple part of the human diet. Besides their nutritional excellence, they have also been shown to contain various functional components, including isoflavones, and have consequently received increasing attention as a functional food item. Isoflavones are structurally similar to 17-β-estradiol and bind to estrogen receptors (ERα and ERβ). The estrogenic activity of isoflavones ranges from a hundredth to a thousandth of that of estrogen itself. Isoflavones play a role in regulating the effects of estrogen in the human body, depending on the situation. Thus, when estrogen is insufficient, isoflavones perform the functions of estrogen, and when estrogen is excessive, isoflavones block the estrogen receptors to which estrogen binds, thus acting as an estrogen antagonist. In particular, estrogen antagonistic activity is important in the breast, endometrium, and prostate, and such antagonistic activity suppresses cancer occurrence. Genistein, an isoflavone, has cancer-suppressing effects on estrogen receptor-positive (ER+) cancers, including breast cancer. It suppresses the function of enzymes such as tyrosine protein kinase, mitogen-activated kinase, and DNA polymerase II, thus inhibiting cell proliferation and inducing apoptosis. Genistein is the most biologically active and potent isoflavone candidate for cancer prevention. Furthermore, among the various physiological functions of isoflavones, they are best known for their antioxidant activities. S-Equol, a metabolite of genistein and daidzein, has strong antioxidative effects; however, the ability to metabolize daidzein into S-equol varies based on racial and individual differences. The antioxidant activity of isoflavones may be effective in preventing dementia by inhibiting the phosphorylation of Alzheimer's-related tau proteins. Genistein also reduces allergic responses by limiting the expression of mast cell IgE receptors, which are involved in allergic responses. In addition, they have been known to prevent and treat various diseases, including cardiovascular diseases, metabolic syndromes, osteoporosis, diabetes, brain-related diseases, high blood pressure, hyperlipidemia, obesity, and inflammation. Further, it also has positive effects on menstrual irregularity in non-menopausal women and relieving menopausal symptoms in middle-aged women. Recently, soybean consumption has shown steep increasing trend in Western countries where the intake was previously only 1/20-1/50 of that in Asian countries. In this review, I have dealt with the latest research trends that have shown substantial interest in the biological efficacy of isoflavones in humans and plants, and their related mechanisms.

Abstract
Air pollution is associated with inflammation and oxidative stress, which predispose to several chronic diseases in human. Emerging evidence suggests that the severity and progression of osteoporosis are directly associated with inflammation induced by air pollutants like particulate matter (PM). This systematic review examined the relationship between PM and bone health or fractures. A comprehensive literature search was conducted from January until February 2021 using the PubMed, Scopus, Web of Science, Google Scholar and Cochrane Library databases. Human cross-sectional, cohort and case-control studies were considered. Of the 1500 papers identified, 14 articles were included based on the inclusion and exclusion criteria. The air pollution index investigated by most studies were PM2.5 and PM10. Current studies demonstrated inconsistent associations between PM and osteoporosis risk or fractures, which may partly due to the heterogeneity in subjects' characteristics, study design and analysis. In conclusion, there is an inconclusive relationship between osteoporosis risk and fracture and PM exposures which require further validation.

Abstract
This study has analyzed sex-specific differences in pedestrian and cyclist accidents involving passenger cars. The most frequently injured body regions, types of injuries, which show sex-specific differences and the general accident parameters of females and males were compared. Accident data from three different European countries (Austria, Netherlands, Sweden) were analyzed. The current analysis shows that for both, females and males, pedestrian and cyclist injuries are sustained mainly to the body regions head, thorax, upper extremities and lower extremities. The results show that the odds for sustaining skeletal injuries to the lower extremities (incl. pelvis) in females are significantly higher. It was observed in all datasets, that the odds of females being involved in a rural accident or an accident at night are lower than for males. Elderly pedestrian and cyclist (≥60YO) tend to sustain more severe injuries (AIS2+ and AIS3+) than younger pedestrian and cyclists (<60YO) in some of the datasets. The findings of this study highlight the differences in males and females in both, accident scenarios and sustained injuries. Further investigations are needed to distinguish between gender- and sex-specific differences causing the different injury patterns.

J Clin Med 2021; 10:jcm10112526. [PMID: 34200258 PMCID: PMC8201205 DOI: 10.3390/jcm10112526] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Revised: 05/26/2021] [Accepted: 06/02/2021] [Indexed: 01/07/2023] Open
Abstract
Background: hemorrhagic transformation (HT) is a frequent complication of ischemic stroke, and parenchymal hematoma (PH)-type HT has been shown to correlate with symptomatic deterioration. Because both bone and vascular smooth muscle cells are composed of type 1 collagen, we hypothesized that the integrity of blood vessels around the infarction area might be more damaged in osteoporotic conditions after a cardioembolic stroke. Methods: we measured frontal skull Hounsfield unit (HU) values on brain CT images from cardioembolic stroke patients. We conducted a receiver operating characteristic curve analysis in a large sample registry to identify the optimal HU threshold for predicting osteopenia and osteoporosis. Hazard ratios were estimated using a Cox regression analysis to identify whether osteoporotic conditions were an independent predictor of PH-type HT in patients with cardioembolic stroke. Results: altogether, 600 consecutive patients (>18 years old) with cardioembolic stroke were enrolled over a 12-year period at our hospital. The infarction volume and hypothetical osteoporosis were independent predictive factors for PH-type HT development in patients with cardioembolic stroke. In the male group, hypothetical osteoporosis was an independent predictor for PH-type HT development after cardioembolic stroke (hazard ratio, 4.12; 95% confidence interval, 1.40–12.10; p = 0.010). Conclusions: our study suggests an association between possible osteoporosis and the development of PH-type HT in patients with cardioembolic stroke. Our findings could help to predict PH-type HT by providing a convenient method for measuring the HU value using brain CT images.

Abstract
Abstract
Sedentary lifestyle and physiological menopause are among the risk factors of osteopenia, especially in elderly people. However, bone mineral density decrease can also be observed in young individuals, for instance, due to deficiency of female sex hormones after surgical interventions, particularly ovariectomy. Our research enabled us to assess the efficacy of whole-body vibration in preventing the loss of bone mineral density in the ovariectomy rat osteopenia model. Thus, whole-body vibration with acceleration level 0.3 g and frequency 50 Hz was used on young female rats, which had been subjected to ovariectomy (n = 18). It had been conducted for 24 weeks, exposure time – 30 minutes per day, 5 times a week. Assessment of mineral component loss of the tibia was performed by means of X-ray diffraction. Bone remodeling was assessed by determining hormones: parathyroid hormone and calcitonin, Ca and P in the blood. X-ray diffraction is an effective method, which enables the evaluation a nanocomposites structure of the bone tissue in the experiment. In the article, we applied this method to determine the loss of bone mineral mass after ovariectomy and the impact of whole-body vibration under such conditions. In the ovariectomy group, the volume of a mineral component significantly decreased starting already from the 16th week (р<0.05) versus control. However, in the group with ovariectomy + whole-body vibration, the loss of a mineral component was insignificant during 8-16 weeks of the investigation, compared with the control group. On the 24th day, the spectrums almost did not differ from ovariectomized rats group. Meanwhile, hormone levels changed in ovariectomized rats group. It should be emphasized that the aforementioned whole-body vibration parameters do not cause severe bone damage or further negative consequences.

Abstract
Sexual dimorphism of the skeleton is well documented. At maturity, the male skeleton is typically larger and has a higher bone density than the female skeleton. However, the underlying mechanisms for these differences are not completely understood. In this study, we examined sexual dimorphism in the formation of osteoclasts between cells from female and male mice. We found that the number of osteoclasts in bones was greater in females. Similarly, in vitro osteoclast differentiation was accelerated in female osteoclast precursor (OCP) cells. To further characterize sex differences between female and male osteoclasts, we performed gene expression profiling of cultured, highly purified, murine bone marrow OCPs that had been treated for 3 days with macrophage colony-stimulating factor (M-CSF) and receptor activator of NF-κB ligand (RANKL). We found that 125 genes were differentially regulated in a sex-dependent manner. In addition to genes that are contained on sex chromosomes, transcriptional sexual dimorphism was found to be mediated by genes involved in innate immune and inflammatory response pathways. Furthermore, the NF-κB-NFATc1 axis was activated earlier in female differentiating OCPs, which partially explains the differences in transcriptomic sexual dimorphism in these cells. Collectively, these findings identify multigenic sex-dependent intrinsic difference in differentiating OCPs, which results from an altered response to osteoclastogenic stimulation. In humans, these differences could contribute to the lower peak bone mass and increased risk of osteoporosis that females demonstrate relative to males. © 2021 American Society for Bone and Mineral Research (ASBMR).

Prevalence on 115 Periprosthetic Femoral Fractures Around a Primary Hip Stem. J Arthroplasty 2021; 36:2189-2196. [PMID: 33610412 DOI: 10.1016/j.arth.2021.01.066] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Revised: 01/19/2021] [Accepted: 01/23/2021] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Some periprosthetic femoral fractures (PFFs) present history and radiographic aspect consistent with an atypical femoral fracture (AFF), fulfilling the criteria for AFF except that PFFs by themselves are excluded from the diagnosis of AFFs. The aim of this study is to evaluate in a single institution series of PFFs if any of them could be considered a periprosthetic atypical femoral fracture (PAFF), and their prevalence. METHODS Surgical records were searched for PFFs around a primary hip stem from January 2013 to December 2019. Cases were classified according to Vancouver classification. Demographic and medical history was extracted. Fisher's exact test was used for statistical analysis. RESULTS One hundred fifteen PFFs were identified, 59 of them were type B1 and 16 were type C. Radiographs and medical records were available for all patients. Twenty-four patients (32%) have been treated with bisphosphonates (BPs) for longer than 4 years. Four patients presented a fracture with characteristics of PAFF. When enlarged to all PFFs of the series, no other PAFF was found: prevalence of PAFFs was 5.3% for type B1 and C cases and 3.5% for all surgically treated PFFs. Statistical significative difference between PAFFs and PFFs was found for prolonged BP assumption and for the level of fracture clear of the stem. CONCLUSION Fracture with characteristics of AFFs can also happen over a prosthetic stem, configuring themselves as PAFFs, and they are related to prolonged BP use. As a correct diagnosis is mandatory for proper treatment, a revision of criteria for AFFs should be considered, accepting that PAFFs exist.

Abstract
Sex is a common baseline factor collected in studies that has the potential to be a prognostic factor (PF) in several clinical areas. In recent years, research on sex as a PF has increased; however, this influx of new studies frequently shows conflicting results across the same treatment or disease state. Thus, systematic reviews (SRs) addressing sex as a PF may help us to better understand diseases and further personalize healthcare. We wrote this article to offer insights into the challenges we encountered when conducting SRs on sex as a PF and suggestions on how to overcome these obstacles, regardless of the clinical domain. When carrying out a PF SR with sex as the index factor, it is important to keep in mind the modifications that must be made in various SR stages, such as modifying the PF section of CHARMS-PF, adjusting certain sections of QUIPS and extracting data on the sex and gender terms used throughout the studies. In this paper, we provide an overview of the lessons learned from carrying out our reviews on sex as a PF in different disciplines and now call on researchers, funding agencies and journals to realize the importance of studying sex as a PF.

Abstract
BACKGROUND Current evidence demonstrate that sugar-sweetened beverages (SSBs) and bone health are related; however, there has been only a few reviews on the link between SSBs and bone health. A systematic review and meta-analysis was performed to investigate the association between SSBs consumption and bone health in chidren and adults. METHODS Relevant studies of SSBs and bone health published up to 15 March 2021 were searched using PubMed, the Web of Science, Cochrane Library, and a reference search. A random-effects meta-analysis was conducted to estimate the standardized mean difference (SMD). Subgroup analyses were performed to identify whether effects were modified by age, sex, measured skeletal sites, type of SSBs, and SSBs intake questionnaire. RESULTS Twenty-six publications including 124,691 participants were selected on the review. The results from this meta-analysis showed a significant inverse association between SSBs intake and bone mineral density (BMD) in adults (ES: -0.66, 95% CI: - 1.01, - 0.31, n = 4312). Eighteen of the 20 studies included in the qualitative-only review in children and adults supported the findings from the meta-analysis. When subgroup analysis was performed according to skeletal site, a large effect was found on whole body BMD (ES: -0.97, 95% CI: - 1.54, - 0.40). There was a moderate effect on BMD in females (ES: -0.50, 95% CI: - 0.87, - 0.13). There was a moderate or large effect on BMD in individuals aged under 50 years (under 30 years: ES: -0.57, 95% CI: - 0.97, - 0.17; 30 to 50 years: ES: -1.33, 95% CI: - 1.72, - 0.93). High consumption of carbonated beverages had a moderate effect on BMD (ES: -0.73, 95% CI: - 1.12, - 0.35). CONCLUSION The meta-analysis showed that SSBs consumption such as carbonated beverages were inversely related to BMD in adults. Qualitative review supported the results of meta-analysis.

Abstract
BACKGROUND The burden of age-associated fragility fracture of the pelvis has gradually amplified over the years. Commonly used clinical tools cannot fully explain age-associated fracture risk increase, and microstructural analysis could be required to elucidate pubic bone strength decline in elderly. MATERIAL AND METHODS The study sample encompassed 46 pubic bones obtained from cadaveric donors divided into a young women (<45 years, n = 11), aged women (>60 years, n = 11), young men (<45 years, n = 12) and aged men group (>60 years, n = 12). Micro-computed tomography was used to evaluate the cortical and trabecular microstructure of pubic bone samples. RESULTS Apart from age-associated loss in quantitative trabecular parameters, significant alteration of micro-CT parameters that more closely reflect internal trabecular microarchitectural complexity may contribute to pubic bone strength decline in men and women of advanced age (p < 0.05). Additionally, decreased cortical thickness and increased Ct.Po, Po.Dm and Po.N were found in the anterior and posterior cortical surface of pubic bone samples from the aged individuals (p < 0.05). The more pronounced alteration was noted in aged female donors, illustrated in a significant deterioration trend of the Tb.N, Tb.Sp, and thinner posterior cortical surface with decreased pore spacing (p < 0.05). CONCLUSION Our data suggest that age-associated deterioration in trabecular and cortical pubic bone micro-architecture could unravel a morphological basis for decreased pubic bone strength and increased pubic bone fragility, which leads to fracture predilection in the elderly women. Thus, the individual fracture risk assessment should be advised in the elderly, with a particular accent on aged women.

Abstract
Objectives To investigate changes in bone mineral density (BMD) in patients with early rheumatoid arthritis (RA) over a 10-year period. Methods Consecutive patients with early RA (symptom duration <12 months) were followed according to a structured programme and examined with dual-energy X-ray absorptiometry (DXA) at inclusion and after 2, 5 and 10 years. Mean Z-scores over the study period were estimated using mixed linear effect models. Changes in Z-scores between follow-up visits were analysed using paired T-tests. Results At inclusion, 220 patients were examined with DXA. At the femoral neck, the mean Z-score over 10 years was −0.33 (95 % CI −0.57 to −0.08) in men and −0.07 (−0.22 to 0.08) in women. Men had significantly lower BMD at the femoral neck than expected by age at inclusion (intercept Z-score value −0.35; 95 % CI −0.61 to −0.09), whereas there was no such difference in women. At the lumbar spine, the mean Z-score over the study period for men was −0.05 (−0.29 to 0.19) and for women 0.06 (−0.10 to 0.21). In paired comparisons of BMD at different follow-up visits, femoral neck Z-scores for men decreased significantly from inclusion to the 5-year follow-up. After 5 years, no further reduction was seen. Conclusions In this observational study of a limited sample, men with early RA had reduced femoral neck BMD at diagnosis, with a further significant but marginal decline during the first 5 years. Lumbar spine BMD Z-scores were not reduced in men or women with early RA. Data on 10-year follow-up were limited.
