Filter by:Diseases of bone associated with ageing, including osteoporosis (OP) and osteoarthritis (OA), reduce bone mass, bone strength and joint integrity. Current non-surgical approaches are limited to pharmaceutical agents that are not disease modifying and have poor patient tolerability due to side effect profiles. Developing a fundamental understanding of cellular bone homeostasis, including how key cell types affect tissue health, and offering novel therapeutic targets for prevention of bone disease is therefore essential. This is the focus of OSTEOMICS. A number of factors have been linked to increased risk of bone disease, including genetic predisposition, diet, smoking, ageing, autoimmune disorders and endocrine disorders. In our study, we will recruit patients undergoing elective and non-elective orthopaedic surgery and obtain surgical bone waste for analysis. This will capture a cohort of patients with bone disorders like OP and OA, in addition to patients without overt clinical bone disease. We will study the relationship between the molecular biology of bone cells, bone structure, genetics (DNA) and environmental factors with the aim of identifying and validating novel therapeutic targets. We will leverage modern single cell technologies to understand the diversity of cell types found in bone. These technologies have now led to the characterisation of virtually every tissue in the body, however bone and bone-adjacent tissues are massively underrepresented due to the anatomical location and underlying technical challenges. Early protocols to demineralise bone and perform single cell profiling have now been developed. We will systematically scale up these efforts to observe how genetic variation at the population level leads to alterations in bone structure and quality. Over the next 10 years, we will generate data to comprehensively characterise bone across health and disease, use machine learning to drive analysis, and experimentally validate hypotheses - which will ultimately contribute to developing the next generation of therapeutic agents.
Osteoporosis is a disease characterized by low bone mass and structural deterioration of bone tissue leading to bone fragility (i.e., weakness) and an increased risk for fracture. Bone strength is a critical factor in a bone's ability to resist fracture and is clearly an important outcome in studies of osteoporosis. The current standard for assessing bone health and diagnosing osteoporosis is to use dual-energy x-ray absorptiometry (DXA) to quantify the areal bone mineral density (BMD), typically at the hip and spine. However, DXA-derived BMD has limited discriminatory accuracy for distinguishing individuals that experience fragility fracture from those who do not. One well known limitation of DXA-derived BMD is that it does not adequately assay bone strength. There is a critical unmet need to identify persons more accurately with diminished bone strength who are at high risk of experiencing a fragility fracture in order to determine an appropriate therapy. A potential new diagnostic approach to assess skeletal health and improve osteoporosis diagnosis is the use of Cortical Bone Mechanics Technology (CBMT). CBMT leverages multifrequency vibration analysis to conduct a noninvasive, dynamic 3-point bending test that makes direct, mechanical measurements of ulnar cortical bone. Data indicates that CBMT-derived ulnar flexural rigidity accurately estimates ulnar whole bone strength and provides information about cortical bone that is unique and independent of DXA-derived BMD. However, the clinical utility of CBMT-derived flexural rigidity has not yet been demonstrated. The investigators have designed a clinical study to assess the accuracy of CBMT-derived ulnar flexural rigidity in discriminating post-menopausal women who have suffered a fragility fracture from those who have not. These data will be compared to DXA-derived peripheral and central measures of BMD obtained from the same subjects.
Artificial Intelligence-assisted Diagnosis and Prognostication in Osteoporosis Using Chest X-ray
In the last decade, there has been a shift towards Cone-Beam Computed Tomography (CBCT - regarding its low-dose radiation profile) in Dentistry/Implantology fields because it presents a more conclusive insight in the bone micro-architecture and cortical/trabecular bone structures assessment due to 3D acquisition higher resolution. Despite convergent and interesting preliminary results, most CBCT studies failed in highlighting a potential new osteoporosis diagnostic tool. TOMOSTEOp study aims to explore inter-relation between CBCT parameters and DXA Gold-Standard parameters in order to build resolutive explicative model of bone mineral density and test CBCT diagnostic performances.
The aim of this clinical trial is to investigate the effect of the OsteoStrong training method and the Individually Adapted and Combined Training on the bone health of older women with high fracture risk. Additionally, the aim is also to explore the participants' experiences of each training method. Participants will be randomised to either treatment arm A (OsteoStrong) or treatment arm B (Individually Adapted and Combined Training). Participants in both groups will train for nine months. Treatment arm A will train individually once a week and treatment arm B will train in a group twice a week. Both groups will have a training instructor who will supervise and give training instructions. Researchers will compare the groups to see the effects of the training methods on the participants' bone health among other outcome measures. The participants will be tested at baseline and post-intervention (9 months later).
The initiation of bisphosphonate therapy for osteoporosis requires an assessment of the oral status to prevent the risk of osteonecrosis of the jaw. This recommendation is sometimes a hindrance to the initiation of treatment or may be responsible for a delay in treatment or even the failure to initiate treatment. However, in the case of a severe osteoporotic fracture (femoral or humeral neck fracture, vertebral fracture or pelvic fracture), treatment must be rapid because of the major risk of refracture in the short term (multiplied by 5 in the 2 years following the fracture). In the rheumatology department of the Nice University Hospital, the investigator team take care of patients with osteoporotic fractures either directly in hospital or referred by the orthopedics department as part of a care program. For these patients, the team perform an etiological assessment, bone densitometry and evaluation of the oral status with dental panoramic and tele-expertise to determine if there is an indication to perform surgical care before starting the treatment. Therefore, the investigator aimed to describe the number of patients requiring dental surgery befor the initiation of bisphosphonate or denosumab treatment before to introduce treatment for osteoporosis
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)
