Filter by:It is well known that some chronic respiratory pathologies such as asthma or chronic obstructive pulmonary disease (COPD) are associated with an increased risk of osteoporosis, due to the pathology itself and the therapies implemented (per-os or inhaled corticosteroids). Osteoporosis leads to an increased risk of fragility fracture, with an increased morbidity and mortality associated with severe fractures such as vertebral fractures. Also, osteoporotic vertebral fractures often occur at the thoracolumbar hinge, resulting in worsening of the thoracic kyphosis. However, to the best of our knowledge, the prevalence of osteoporotic vertebral fractures measured by CT scan in patients with interstitial lung disease (ILD) is not known. For these patients who already have impaired respiratory function, the appearance of vertebral fractures could impact their management and worsen their prognosis (additional restrictive syndrome, difficulties in analgesics management because of respiratory contraindications, difficulties in wearing a corset, etc...). In this context, it appears interesting to define the prevalence of osteoporosis and osteoporotic vertebral fractures at the thoracic spine and the thoraco-lumbar hinge in a population of patients followed for ILD. So, the main objective of this study is to describe the prevalence of vertebral osteoporotic fractures in an overall cohort of patients with ILD.
This project aims to improve the global outcome for an aging individual after a traumatic fall, through identifying conditions contributing to a fall and promoting recovery and rehabilitation. Through better understanding 'falling phenotype', the ultimate aim is to prevent future complications, as well as new falls and fractures in the growing older population.
The aim of this study is to investigate the effect of romosozumab on bone cells during early and late phases of treatment.
This was a cross-sectional study. Patients who attended the osteoporosis clinic of Kowloon Hospital from June to December 2022 were recruited. Grip strength and appendicular skeletal muscle mass index were measured with a Jamar dynamometer and a bioimpedance analyser. Since most patients in our clinic are of Chinese ethnicity, the diagnostic criteria in the Consensus Update on Sarcopenia Diagnosis and Treatment by the Asian Working Group for Sarcopenia in 2019 was utilised. The diagnosis of sarcopenia was established by the presence of both low grip strength (Male: < 28 kg, Female < 18 kg) and low appendicular skeletal mass (Male: < 7.0 kg/m2, Female: < 5.7 kg/m2)
OPTIMAL is a pilot feasibility study for a machine learning (ML) based enhanced screening software for osteoporosis. This tool has been created using machine learning, based on data from NHS Greater Glasgow and Clyde. The study will contact individuals deemed at high risk by the study (750 patients will be re-identified, and these will be contacted starting from the highest risk until 250 patients are recruited) and perform DXA scans, clinical review, and bloods tests that are relevant to osteoporosis. This data will then be compared to the predictions made by the OPTIMAL enhanced screening tool, in order to test how effective it is.
In this cross-sectional clinical study, we will examine the bones of 111 Type 1 Diabetes (T1D) patients and 37 age-matched healthy controls with the aim of describing a T1D Bone Phenotype. The main Objectives of the study is a) to determine if the material properties of the bones are affected in diabetic bone disease and b) to determine if the mitochondrial function in osteoclasts and osteoblasts is impaired in T1D. Secondary end points are c) to establishment of the T1D bone phenotype and d) to investigate if mitochondrial dysfunction in T1D bone cells correlates to changes in gene expression, gene activity, bone remodelling, bone density, microarchitecture, geometry and material properties. Furthermore, in terms of contributing to knowledge on etiology and pathology of type one diabetic bone disease, we will study the predictory value of muscle mass in T1D patients and controls, as well as other characteristics such as heart rate variability (HRV) and AGE content. Furthermore, we will study the epidemiology of osteoporosis and fractures in Danish T1D patients. To assess the material properties of the bones, we will measure the bone mass density (BMD), use High Resolution peripheral Quantitative Computed Tomography (HRpQCT) for assessment of the microarchitecture and finite element analysis of bone strength, and by microindentation, we will obtain direct measures of the strength of the cortical bone of the tibia. Further we will measure bone turnover markers and circulating microRNA and in a subgroup of participants (24 T1D, 12 controls) bone samples will be retrieved for examination of bone histomorphometry (structural and static parameters) and cell samples from blood and bone marrow will be used for in vitro experiments focused on cell differentiation mitochondrial function, as hyperglycemia may affect mitochondrial function. Finally measures of some possible predictors of bone fragility in subjects with T1D are examined (sarcopenia, skin advanced glycation end products (AGE) content, autonomic neuropathy)
Osteosarcopenia is a geriatric musculoskeletal syndrome characterized by co-existence of osteoporosis and sarcopenia (low skeletal muscle mass, strength, and/or functional capacity). There is strong evidence of overlap between the pathophysiology of osteoporosis and sarcopenia (muscle-bone crosstalk). This research plan will further explore the relationship between bone and muscle, and provide new information about effect of osteoporosis medications on muscle health in older adults who are under treatment for osteoporosis.
The aims of ZOLARMAB2 are fourfold. First, the investigators want to investigate if multiple infusions of zoledronate can prevent the rebound activation of bone turnover and the subsequent bone loss in patients previously treated with denosumab and if there is difference between infusing zoledronate at fixed time-points after the last injection of denosumab or when bone turnover is increased. Second, the investigators want to investigate if bone loss will resume after controlling the rebound activation of bone turnover during the first year after denosumab discontinuation and if this can be prevented by yearly infusions of zoledronate. Third, the investigators want to investigate the underlying pathophysiological mechanisms by investigating biochemical markers, osteoclast and osteoblast activation signals in the bone and bone marrow, and the pool of preosteoclasts/mature osteoclasts before and after treatment with zoledronate. Fourth, the investigators want to investigate the effect of denosumab discontinuation on muscle mass and muscle strength and on insulin sensitivity.
70 postmenopausal women, aged 50 to 60, who are vitamin D deficient and diagnosed with osteoporosis or osteopenia with T score of DEXA of lumbar spine (L1 to L4) was less than or equal -1 and their body mass index between 25 and 30 kg/m2. They will be divided into two groups by randomization. 35 postmenopausal women in Group (A) will undergo three weekly sessions of UV therapy in addition to routine aerobic activity and vitamin D supplements (800 IU) daily for three months. For three months, group (B), which consists of 35 postmenopausal women, will undergo daily aerobic exercise and vitamin D supplementation (800 IU) only. The amount of serum 25-hydroxyvitamin D was measured using ELISA kits, bone mineral density of lumber spine was measured by dual energy X-ray absorptiometry (DEXA), and the torque of knee flexors and extensors was evaluated using the Biodex System 3 isokinetic dynamometer,
This study will provide objective evidence for the efficiency and safety of minodronate in the treatment of postmenopausal osteoporosis with low back pain protocol. Furthermore, it will be helpful to evaluate the quantitative relationship between bone metabolic markers (BTM) and bone mineral density (BMD) in patients with osteoporosis under different ages.
