Correlation of bone mineral density with MRI T2* values in quantitative analysis of lumbar osteoporosis

AbstractSummaryWe found that the MRI T2* value is moderately negatively correlated with the bone mineral density assessed with quantitative computed tomography in evaluating osteoporosis in postmenopausal women and may have some potential in assessing severity of lumbar osteoporosis for scientific research.PurposeTo investigate the T2* quantitative measurement in magnetic resonance imaging (MRI) and its correlation with the bone mineral density (BMD) values evaluated with quantitative computed tomography (QCT) in women with postmenopausal lumbar vertebrae osteoporosis.Materials and methodsEighty-seven postmenopausal women were enrolled who had MRI scanning with T1WI, T2WI, and T2* mapping sequences and QCT evaluation of BMD. The T2* value and the BMD were assessed in lumbar vertebral bodies 2 –4. Based on the BMD values, the patients were divided into three groups: normal, osteopenia, and osteoporosis.ResultsThe inter- and intra-observer intraclass correlation coefficients (ICCs) for T2* were 0.91 (0.87 –0.94, 95% CI) and 0.93 (0.88–0.95, 95% CI), respectively. The inter- and intra-observer ICCs for the BMD value were 0.89 (0.83–0.92, 95% CI) and 0.91 (0.86–0.93, 95% CI), respectively. The differences of the T2* values and BMD among the three groups were statistically significant (P

Authors: Intriago M, Maldonado G, Guerrero R, Messina OD, Rios C Abstract Objective: To study the association between osteoporosis and sarcopenia and determine the prevalence of osteosarcopenia in patients who attended a rheumatology center in Ecuador. Methods: A cross-sectional study was conducted in a population of patients who had a densitometric study. The diagnosis of sarcopenia was determined by the DXA standard gold test, screening, and conventional methods (bioimpedance, anthropometric measurements, SARC-F, muscle function, and gait test). Results: A total of 92 patients were studied. The median age...

AbstractPurpose of ReviewThe aim of this narrative review is to summarise recent literature on the effects of exercise and nutrition interventions alone or in combination on muscle and bone loss in people with cancer.Recent FindingsThere is emerging evidence to support the inclusion of targeted exercise and nutrition strategies to counter loss of muscle and bone associated with cancer treatments. Although research in this field is advancing, the optimal exercise and nutrition prescription to combat cancer-related bone and muscle loss remain unknown.SummaryThis review identifies specific components of nutrition and exercise...

ConclusionThis KPI set compliments the existing Best Practice Framework to support FLSs to examine their own performance using patient-level data. By using this KPI set for local quality improvement cycles, FLSs will be able to efficiently realise the full potential of secondary fracture prevention and improved clinical outcomes for their local populations.

In this study, we showed that osteoporosis is highly associated with reduction in hematopoietic autophagy activity in humans. We showed that an autophagy defect in the hematological system leads to severe bone loss. The disturbed osteocyte homeostasis is apparently caused by impaired type H blood vessels and possibly an aberrant alteration in the extracellular matrix (ECM) pathways that govern osteocyte homeostasis in hematopoietic autophagy-defective mice. Our results thus suggest that autophagy in the adjacent hematopoietic cells is essential to maintain bone homeostasis, and chronic hematopoietic autophagy deficiency ca...

(Natural News) Fasting can improve reproductive and mental health, as well as lower the risk of musculoskeletal disorders in women, according to a recent review published in the Journal of Mid-Life Health. Researchers from the National Institute of Naturopathy in India found evidence that fasting not only prevents metabolic disorders, but it also improves bone health. The...

AbstractFragility hip fractures and their associated morbidity and mortality pose a global healthcare problem. Several pharmaceutical products have been postulated to alter bone architecture and contribute to fragility hip fractures. We searched four electronic databases from inception to September 2017. Inclusion criteria were the following: (1) adult patients with fragility hip fractures, (2) full text in English, (3) minimum one-year follow-up, and (4) reporting of at least one risk factor. To minimize heterogeneity among the studies, we performed subgroup analyses. Whenever heterogeneity remained significant, we employ...

AbstractSummaryThe prevalence of unknown vertebral fractures evaluated by systematic vertebral fracture assessment (VFA) was 21% in patients over 50  years of age who suffered from a recent low-trauma non-severe peripheral fracture. The outcome of VFA resulted in changes in the management of osteoporosis.IntroductionThe aim of this study was to evaluate the utility of VFA in detecting vertebral fractures (VFs) in patients over 50  years of age, who suffered from a recent low-trauma non-severe peripheral fracture.MethodsThis was an observational, single-center, cross-sectional study conducted in patients over 50 &...
