Purpose: The Guangzhou Nutrition and Health Study (GNHS) aims to assess the determinants of risk of osteoporosis and cardio-metabolic diseases and changes in their relevant indices in nutritional aspects, as well as other environmental and genetic factors. Study design: GNHS is a community-based prospective cohort study. Participants: About 4540 apparently healthy residents, living in Guangzhou city (South China) for >5 years, aged 40-80 years, recruited between 2008 and 2013. Visits and Data Collection: Participants were/will be visited every three years by invited to the School of Public Health, Sun Yat-sen University. At each visit, face-to-face interviews, specimen collection, anthropometric measurements, DXA scanning, ultrasonography evaluation were/will be conducted. Up to May 2017, 3400 and 2380 subjects completed the 2nd and 3rd visits. Key variables: 1. Questionnaire interviews: Structured questionnaires were/will be used to collect the participants' socio-demographic characteristics, lifestyle factors, menstruation and reproductive history (women only), sleep quality, family history, psychological health, social support and participation, cognitive function, habitual dietary intake, use of supplements and history of chronic diseases. 2. Physical examinations: Anthropometric measurements, blood pressure tests, handgrip strength, and usual gait speed. 3. DXA scanning: A dual-energy x-ray absorptiometry (DXA) was/will be used to determine bone density and bone mineral content, bone geometry information, fat mass and muscle mass. 4. Ultrasonography evaluations: Ultrasonography evaluation was/will be performed to determine carotid artery intima-media thickness and plaque, and fatty liver. 5. Specimen collections: Overnight fasting blood sample and early morning first-void urine sample and faces samples were/will be collected, separated and stored at −80°C till tests. 6. Laboratory tests: 1. Blood tests: Metabolic syndrome-related indices; inflammatory markers; sexual hormones and SHBG; genetic markers; nutritional indices (e.g., carotenoids; fatty acids; minerals, folate, betaine, choline, and vitamin D, etc.) 2. Urinary tests: Flavonoids and flavones; minerals; creatinine and renal function related markers 3. Fecal test: Gut microbiota and related metabolites. 7. Morbidity and mortality: Relevant data were/will be also retrieved via local multiple health information systems.
The purpose of this study is to compare the effects of two teriparatide products, PF708 and Forteo, in patients with osteoporosis.
This study aims to create a database of patients with stable and chronic heart failure with comprehensive assessment of bone, skeletal and vascular status. RoC-HF will facilitate cross-sectional and, eventually, longitudinal mechanistic epidemiological analyses to disentangle the role of the bone- vascular axis in chronic heart failure. Blood and urine samples will be stored to facilitate future biomarker analyses.
The purpose of this study is to evaluate the follow-up of the osteoporotic patient by a physician-pharmacist collaboration.
Osteoporosis (OP) and subsequent fractures (OP fractures) are a source of morbidity and high mortality in the elderly. Despite numerous programs aiming at improving OP care, the prevention, diagnostic and treatment remain suboptimal. Barriers to a better care are multiple, both in the general and at-risk population, and in medical practitioners. Since they do not perceive their susceptibility to OP, people do not see the benefit of prevention. In addition, physicians do not give sufficient importance to OP prevention and care, despite the existence of guidelines. The investigators implemented a qualitative study to explore the knowledge and representations regarding osteoporosis in the general and at-risk population and in doctors in Rhône-Alpes Region, France, using focus groups with women and men and semi-structured face-to-face interviews with general practitioners. Understanding barriers to osteoporosis care in patients and general practitioners will help to set up effective strategies to improve prevention and treatment.
Patients with Systemic lupus erythematosus (SLE) are known to present an increased risk of osteoporosis and cardiovascular calcification. It has also been suggested that bone remodelling and cardiovascular calcification are regulated by the same mechanisms, but inversely in terms of calcium deposition, as osteoporosis is often associated with cardiovascular calcification. Inflammatory and immune factors have been implicated in these two processes. The role of the RANKL/OPG system in osteoclast differentiation has been elucidated over the last ten years. RANKL induces differentiation of monocytes-macrophages into osteoclasts, while, inversely, OPG exerts an inhibitory role by inactivating RANKL. Differentiation of smooth muscle cells into osteoblasts in the vessel wall induces calcification, and this phenomenon is counterbalanced by differentiation of monocytes into osteoclasts. Although the role of the RANKL/OPG ratio in the pathogenesis of osteoporosis has now been clearly established, its role in vascular calcification is only hypothetical at the present time. This study will focus on patients with SLE diagnosed and followed in the Amiens University Hospital Internal Medicine and Nephrology departments
A multicenter, randomized, double-blind, placebo-controlled study to evaluate the effect of 6 months treatment with Romosozumab compared to placebo by determining the percent changes in bone mineral density
The aim of Patient-Centred Innovations for Persons With Multimorbidity (PACE in MM) study is to reorient the health care system from a single disease focus to a multimorbidity focus; centre on not only disease but also the patient in context; and realign the health care system from separate silos to coordinated collaborations in care. PACE in MM will propose multifaceted innovations in Chronic Disease Prevention and Management (CDPM) that will be grounded in current realities (i.e. Chronic Care Models including Self-Management Programs), that are linked to Primary Care (PC) reform efforts. The study will build on this firm foundation, will design and test promising innovations and will achieve transformation by creating structures to sustain relationships among researchers, decision-makers, practitioners, and patients. The Team will conduct inter-jurisdictional comparisons and is mainly a Quebec (QC) - Ontario (ON) collaboration with participation from 3 other provinces: British Columbia (BC); Manitoba (MB); and Nova Scotia (NS). The Team's objectives are: 1) to identify factors responsible for success or failure of current CDPM programs linked to the PC reform, by conducting a realist synthesis of their quantitative and qualitative evaluations; 2) to transform consenting CDPM programs identified in Objective 1, by aligning them to promising interventions on patient-centred care for multimorbidity patients, and to test these new innovations' in at least two jurisdictions and compare among jurisdictions; and 3) to foster the scaling-up of innovations informed by Objective 1 and tested/proven in Objective 2, and to conduct research on different approaches to scaling-up. This registration for Clinical Trials only pertains to Objective 2 of the study.
Background: Cardiovascular disease (CVD), osteoporosis and dementia are chronic diseases of ageing that impact adversely on the lives of those affected and have major health, social and economic consequences. A number of factors are considered to be implicated in these diseases, ranging from the more established factors to those that are less well recognised. Lifestyle factors such as diet, body weight, smoking, physical activity and years of education are acknowledged as risk factors for the development of these chronic diseases of aging. Emerging research suggests that elevated homocysteine and/or sub-optimal status of the metabolically related B-vitamins (folate, vitamin B12, B6 and riboflavin) may be associated with a higher risk of age-related disease. The interplay between relevant genetic and nutrient factors (gene-nutrient interactions) is considered to be highly relevant in the development (and prevention) of chronic diseases of ageing, however this relatively new area of research is as yet poorly understood. The collection of clinical, lifestyle, nutritional and genetic data on large numbers of patients would permit the investigation of those nutrients which interact with specific genes to increase the likelihood of a person developing chronic diseases of ageing. Aim: The aim of the TUDA study is to collect detailed clinical, lifestyle, dietary, genetic and biochemical data to investigate gene-nutrient interactions (particularly from the perspective of the B-vitamins and vitamin D/calcium) in the development of CVD, osteoporosis and dementia by studying older adults exhibiting the early stages of these common diseases, namely hypertension, low bone mineral density, and early memory loss, respectively. Secondary aim (follow up TUDA investigation): The aim of this longitudinal investigation is to re-assess clinical, nutritional, genetic and biochemical factors in relation to the progression of disease outcomes in TUDA study participants, in subsequent years after initial investigation. Study design: A total of 6000 non-institutionalised older Irish people aged over 60 years with early predictors of either dementia, stroke and osteoporosis (namely early memory loss, high blood pressure and low bone mineral density, respectively) recruited from three centres (St James's Hospital Dublin, Ulster University Coleraine and The Clinical Translational Research and Innovation Centre (C-TRIC), Londonderry) across Ireland. Non-fasting blood samples were collected from all subjects and routine blood biochemistry profiles and biomarkers of relevance to B vitamin and vitamin D status were measured. Supplement use was recorded and a targeted food frequency questionnaire was used to record dietary intakes of specific vitamins of interest (folate, B12, B6, riboflavin and D) from major food sources, particularly fortified foods. Physiological function tests including blood pressure, bone health (DXA scans) and cognitive function tests and anthropometric measures were also taken.
This is multiple center, prospective study aiming to investigate the tracking and outcome of patients attending Greek General hospitals with low-trauma fractures. Secondary end-points were to facilitate the implementation of coordinated, multi-disciplinary models of care for secondary fracture prevention, and to monitor osteoporosis treatment initiation, osteoporosis treatment persistence at 12 months, compliance, and subsequent fractures.
