Osteosarcopenia is a newly described syndrome that describes the co-existence of osteoporosis and sarcopenia, two chronic musculoskeletal conditions associated with ageing. Osteoporosis, a condition of low bone mass and micro-architectural deterioration of bone, and sarcopenia, the loss of muscle mass, strength and function, often co-exist in a frail subset of the elderly population, leading to significantly worsened outcomes than seen in either condition alone. These include a greater risk of f ...[more]

Project description:This cross-sectional study investigated osteosarcopenia prevalence and its correlates among 2142 adults aged 55 and older in Finland. Findings show 3.9% had osteosarcopenia, while 13.8% and 11.1% had probable sarcopenia only or osteoporosis only, respectively. Osteosarcopenia was associated with low BMI, impaired mobility, ADL limitations and depression. Sarcopenia appeared to drive these associations more than osteoporosis. Osteosarcopenia may be a risk factor for functional decline, hospitalization, and institutionalization, warranting further research.PurposeOsteosarcopenia is a disorder consisting of concurrent osteoporosis and sarcopenia. This cross-sectional study using nationally representative data from Finland in 2000 aimed to determine the prevalence of osteosarcopenia in Finland. In addition, associations of sociodemographic, lifestyle, anthropometric, physical and mental function indicators, chronic conditions and various biomarkers with osteosarcopenia were examined.MethodsThe study included 2142 subjects aged 55 and over (mean age 68.0 years, SD 9.0). Probable sarcopenia was defined as grip strength < 27 kg for men and < 16 kg for women. Osteoporosis was defined as either ultrasound-based bone density measurement of T < -2.5, or self-reported, pre-existing diagnosis of osteoporosis. Participants were categorized into 4 groups: no sarcopenia and no osteoporosis, probable sarcopenia only, osteoporosis only, and osteosarcopenia. Information on sociodemographic, lifestyle, anthropometric, physical and mental function indicators, chronic conditions and various biomarkers were collected via structured interview, questionnaires, clinical examination, and blood and urine samples.ResultsThe prevalence of probable sarcopenia, osteoporosis and osteosarcopenia was 13.8%, 11.1%, and 3.9%, respectively. Osteosarcopenia was associated with low BMI, slow gait speed, impaired mobility, impaired ability in the activities of daily living and depression. Of the two components, probable sarcopenia appeared to contribute to these associations more than osteoporosis.ConclusionAccording to representative population-based study, about every fifth person with probable sarcopenia also has osteoporosis. Mobility and ADL limitations were more common among people with osteosarcopenia than those with osteoporosis or probable sarcopenia alone. Future studies are needed to examine osteosarcopenia as an independent risk factor for functional decline, hospitalization, and institutionalization.

Project description:Osteopenia/osteoporosis and sarcopenia are common geriatric diseases among older adults and harm activities of daily living (ADL) and quality of life (QOL). Osteosarcopenia is a unique syndrome that is a concomitant of both osteopenia/osteoporosis and sarcopenia. This review aimed to summarize the related factors and clinical outcomes of osteosarcopenia to facilitate understanding, evaluation, prevention, treatment, and further research on osteosarcopenia. We searched the literature to include meta-analyses, reviews, and clinical trials. The prevalence of osteosarcopenia among community-dwelling older adults is significantly higher in female (up to 64.3%) compared to male (8-11%). Osteosarcopenia is a risk factor for death, fractures, and falls based on longitudinal studies. However, the associations between osteosarcopenia and many other factors have been derived based on cross-sectional studies, so the causal relationship is not clear. Few studies of osteosarcopenia in hospitals have been conducted. Osteosarcopenia is a new concept and has not yet been fully researched its relationship to clinical outcomes. Longitudinal studies and high-quality interventional studies are warranted in the future.

Project description:AimOsteopenia and sarcopenia, features of the aging process, are recognized as major health problems in an aging society. This study investigated the prognostic impact of osteosarcopenia, the coexistence of osteopenia and sarcopenia, in older adults undergoing curative resection for colorectal cancer.MethodsWe retrospectively reviewed data of older adults aged 65-98 y who had undergone curative resection for colorectal cancer. Osteopenia was evaluated by bone mineral density measurement in the midvertebral core of the 11th thoracic vertebra on preoperative computed tomography images. Sarcopenia was evaluated by measuring the skeletal muscle cross-sectional area at the third lumbar vertebra level. Osteosarcopenia was defined as the coexistence of osteopenia and sarcopenia. We explored the relationship of preoperative osteosarcopenia with the disease-free and overall survival after curative resection.ResultsAmong the 325 patients included, those with osteosarcopenia had significantly lower overall survival rates than those with osteopenia or sarcopenia alone (P < 0.01). In the multivariate analysis, male sex (P = 0.045), C-reactive protein-to-albumin ratio (P < 0.01), osteosarcopenia (P < 0.01), pathological T4 stage (P = 0.023), and pathological N1/N2 stage (P < 0.01) were independent predictors of disease-free survival, while age (P < 0.01), male sex (P = 0.049), C-reactive protein-to-albumin ratio (P < 0.01), osteosarcopenia (P < 0.01), pathological T4 stage (P = 0.036), pathological N1/N2 stage (P < 0.01), and carbohydrate antigen 19-9 (P = 0.041) were independent predictors of overall survival.ConclusionOsteosarcopenia was a strong predictor of poor outcomes in older adults undergoing curative resection for colorectal cancer, suggesting an important role of osteosarcopenia in an aging society.

Project description:Osteosarcopenia and frailty have a negative health impact on an aging society. This cross-sectional study aimed to investigate the clinical characteristics and relationship of osteosarcopenia and frailty in 291 patients with chronic liver disease (CLD), who comprised 137 males and 154 females, with a median age of 70.0 years. Sarcopenia was diagnosed according to the Japan Society of Hepatology criteria. Bone mineral density was measured using dual-energy X-ray absorptiometry. Frailty was defined by five parameters (exhaustion, slowness, weakness, low physical activity, and weight loss). Among the 291 patients, 49 (16.8%) and 81 (27.8%) had osteosarcopenia and frailty, respectively. Frailty and vertebral fracture were more frequently noted in patients with osteosarcopenia than in those without osteosarcopenia (79.6% vs. 17.4% and 59.2% vs. 20.2%, respectively; p < 0.001 for both). Meanwhile, osteosarcopenia and vertebral fracture were more frequently observed in patients with frailty than in those without frailty (48.1% vs. 4.8% and 49.4% vs. 18.1%, respectively; p < 0.001 for both). On multivariate analysis, frailty was an independent factor associated with osteosarcopenia (odds ratio (OR), 9.837; p < 0.001), and vice versa (OR, 10.069; p < 0.001). Osteosarcopenia and frailty were prevalent, closely interrelated, and increased the risk of vertebral fracture in patients with CLD.

Project description:BackgroundOsteosarcopenia, defined as the coexistence of sarcopenia and osteoporosis, is associated with adverse clinical outcomes. The present study investigated the prognostic significance of osteosarcopenia in patients with cirrhosis.MethodsThis retrospective study evaluated 126 patients with cirrhosis. Participants were classified into three groups based on the presence or absence of (1) sarcopenia and/or osteoporosis; and (2) Child-Pugh (CP) class B/C cirrhosis and/or osteosarcopenia, and the cumulative survival rates were compared between the groups. Cox proportional hazards model was used to identify independent factors associated with mortality. Sarcopenia and osteoporosis were diagnosed according to the Japan Society of Hepatology and the World Health Organization criteria, respectively.ResultsAmong the 126 patients, 24 (19.0%) had osteosarcopenia. Multivariate analysis identified osteosarcopenia as a significant and independent prognostic factor. The cumulative survival rates were significantly lower in patients with osteosarcopenia than in those without (1/3/5-year survival rates = 95.8%/73.7%/68.0% vs. 100%/93.6%/86.5%, respectively; p = 0.020). Patients with osteosarcopenia, but not sarcopenia or osteoporosis alone, had significantly lower cumulative survival rates than those without both conditions (p = 0.019). Furthermore, patients with both CP class B/C and osteosarcopenia had significantly lower cumulative survival rates than those without both (p < 0.001) and with either condition (p < 0.001).ConclusionsOsteosarcopenia was significantly associated with mortality in patients with cirrhosis. The cumulative survival rates were lower in patients with osteosarcopenia than in those without both conditions. Additionally, comorbid osteosarcopenia worsened the prognosis of patients with CP class B/C. Therefore, simultaneous evaluation of both sarcopenia and osteoporosis is crucial to better predict the prognosis.

Project description:There is growing interest in "osteosarcopenia" as the coexistence of osteoporosis and sarcopenia exacerbates negative outcomes. However, limited information is available regarding the risk factors of osteosarcopenia development in patients with osteoporosis. Therefore, we retrospectively reviewed 276 consecutive patients with postmenopausal osteoporosis who regularly visited Showa University Hospital. Patients were eligible for the study if they were ?65 years of age and underwent dual-energy X-ray absorptiometry, blood sampling, and physical performance assessment. Patients were divided into the osteosarcopenia and osteoporosis alone groups according to the diagnostic criteria of the Asian Working Group for Sarcopenia. Of the 276 patients with osteoporosis, 54 patients (19.6%) had osteosarcopenia. Patients in the osteosarcopenia group had a greater risk of frailty than did those in the osteoporosis alone group (odds ratio 2.33; 95% confidence interval, 1.13-4.80, P = 0.028). Low body mass index seemed to be the strongest factor related to the development of osteosarcopenia, and none of the patients in the osteosarcopenia group were obese (BMI ?27.5 kg/m2). Multiple logistic analyses revealed that patients aged 65-74 years who had comorbidities such as kidney dysfunction and high levels of HbA1c were at risk of developing osteosarcopenia. Thus, we strongly recommend the assessment of the key components of the diagnosis of osteosarcopenia in an osteoporosis clinic for patients with low body mass index. Furthermore, appropriate assessments, including comorbidities, will help in identifying patients at greater risk of developing osteosarcopenia.

Project description:IntroductionOsteosarcopenia is defined as the concomitant occurrence of sarcopenia and osteopenia or osteoporosis. Older adults with this syndrome have a greater fragility and mortality risk compared with those without these conditions. Based on separate interventions with individuals with sarcopenia and osteoporosis, exercise has been recommended as a treatment for osteosarcopenia. However, there is no evidence of its efficacy. Our objective is to identify whether physical exercise can improve osteosarcopenia in older adults and lead to good health outcomes.Methods and analysisWe will perform a systematic review in the following databases: PubMed, Embase, Cochrane and Scopus. The criterion of inclusion will be clinical trials involving physical exercise interventions in older adults diagnosed with osteosarcopenia. To assess the risk of bias, the Grading of Recommendations, Assessment, Development and Evaluation and Downs and Black tools will be used. For each search result, the quality of the evidence will ultimately receive one of four grades: high, moderate, low or very low. The outcome of this study is to demonstrate the effectiveness of physical exercise in improving the parameters that lead to the diagnosis of osteosarcopenia (bone mineral density, quality of muscle mass, muscle strength and physical function) in older adults. The possibility of meta-analysis will be assessed according to the homogeneity of the studies, using the methods of fixed or random effects. Sensitivity analyses will be performed, and the funnel plot will be used to assess publication bias. The proposed statistical analyses will be performed using STATA software, V.14.0.Ethics and disseminationThe results of the systematic review will be disseminated via publication in a peer-reviewed journal and presented at a relevant conference. As we will not use individual patient data, ethical approval is not required.Trial registration numberCRD42020215659.

Project description:ObjectivesBody composition alterations occur during aging. The purpose of the present analysis was to explore the functional consequences of the overlap of sarcopenia and osteoporosis, and the potential role of insulin-like growth factor 1 (IGF1) in their development in the oldest old.Setting and participantsEighty-seven nonagenarians from the Louisiana Healthy Aging Study were included.MeasuresThe definition of sarcopenia was based on appendicular lean mass (ALM). Osteoporosis was diagnosed based on bone mineral density (BMD) T score. Four phenotypes were compared: (1) healthy body composition, that is, nonosteoporotic nonsarcopenic (CO, control group), (2) osteoporotic (O, low BMD T score), (3) sarcopenic (S, low ALM), and (4) osteosarcopenic (OS, low BMD T score and low ALM). Sex- and age-specific IGF1-Standard Deviation Scores (SDS) were calculated. The Continuous Scale-Physical Functional Performance (CS-PFP) test was performed.ResultsIn OS men, IGF1-SDS values (-0.61 ±0.37 vs -0.04 ± 0.52, P = .02) were lower than those in CO males (control group), whereas IGF1-SDS were similar in the 4 body composition phenotypes in women. In men only, ALM was positively associated with IGF1-SDS values (P = .01) independent of age and C-reactive protein concentration. Regarding bone health, we found no association between IGF1-SDS values and BMD. IGF1-SDS was not associated with functional performance (CS-PFP) in men and women.Conclusions/implicationsIGF1 sensitivity in skeletal muscle and bone may differ by sex in the oldest old. IGF1 status did not appear to affect physical functionality. Determinants and clinical and functional characteristics of osteosarcopenia need to be further investigated in order to define conclusive diagnostic criteria.

Project description:Aging is considered to be accelerated by insulin signaling in lower organisms, but it remained unclear whether this could hold true for mammals. Here we show that mice with skeletal muscle-specific double knockout of Akt1/2, key downstream molecules of insulin signaling, serve as a model of premature sarcopenia with insulin resistance. The knockout mice exhibit a progressive reduction in skeletal muscle mass, impairment of motor function and systemic insulin sensitivity. They also show osteopenia, and reduced lifespan largely due to death from debilitation on normal chow and death from tumor on high-fat diet. These phenotypes are almost reversed by additional knocking out of Foxo1/4, but only partially by additional knocking out of Tsc2 to activate the mTOR pathway. Overall, our data suggest that, unlike in lower organisms, suppression of Akt activity in skeletal muscle of mammals associated with insulin resistance and aging could accelerate osteosarcopenia and consequently reduce lifespan.

Project description:BackgroundOsteosarcopenia, a combination of osteopenia/osteoporosis and sarcopenia, is a common condition among older adults. While numerous studies and meta-analyses have been conducted on the treatment of osteoporosis, the pharmacological treatment of osteosarcopenia still lacks evidence. Denosumab, a human monoclonal antibody, has shown encouraging results for the treatment of osteosarcopenia. Our systematic review and meta-analysis aimed to investigate the potential dual role of denosumab as an anti-resorptive agent and for other beneficial muscle-related effects in patients with osteosarcopenia, and to evaluate whether denosumab can be a treatment of choice compared to bisphosphonate.MethodsRelevant literature was collated from the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, and Google Scholar databases. The primary outcome was denosumab's effect on lumbar spine bone mineral density (LS BMD), handgrip strength, and gait speed change. The secondary outcome was the effect of denosumab on appendicular lean mass (ALM). The outcomes were presented as mean difference (MD). A random effects model was used in the analysis to represent the population. The risk of bias was assessed using funnel plots.ResultsOut of the 3,074 studies found, four full-text studies met the inclusion criteria, including 264 and 244 participants in the intervention and control groups, respectively. Regarding a primary outcome, our meta-analysis showed that denosumab showed no significant differences in LS BMD and gait speed changes compared to other agents-MD=0.37, 95% confidence interval (CI), -0.35 to 0.79; p=0.09 and MD=0.11; 95% CI, -0.18 to 0.40; p=0.46, respectively. Denosumab had a significant effect on handgrip strength change compared to standard agents-MD=5.16; 95% CI, 1.38 to 18.94; p=0.007, based on the random effects model.ConclusionsDenosumab was better than bisphosphonate and placebo in improving muscle strength (handgrip strength). Therefore, denosumab may be favored in individuals with osteosarcopenia to improve muscular performance and reduce fall risk.
