Filter by:The purpose of this study is to validate a revised food frequency questionnaire that is designed to capture vitamin D, calcium and protein intake in a population of elderly men and women with fragility fractures. Protein, calcium and protein intake will be correlated with biochemical measures and bone mineral density measured by DXA.
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.
The purpose of this study is to compare the pharmacokinetics (blood levels) of two teriparatide products, PF708 and Forteo, in healthy subjects.
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.
Bone responds according to the load placed on it. In this study, investigators want to know if exercise that loads the body in exercises, like walking or jogging (Ground Reaction Forces: GRF), affects bone differently than exercises that load the joints, like weight lifting (Joint Reaction Forces: JRF). Participants will exercise at least 3 times a week for 6 months. Measures of bone strength and mass, muscular strength, and aerobic fitness will be taken at the beginning and the end of the 6 month program. Period blood samples will be taken for future analysis of blood markers.
Ibandronate is a third-generation biphosphonate with recognized antiresorptive efficacy by several international, randomized, double-blind, controlled trials. These studies have not included patients from central america, to the best of our knowledge. Therefore, this open-label, uncontrolled study, was set out to assess the clinical effects of a 6-m treatment course with Ibandronate plus vitamine D and Calcium on bone mineral density and health-related quality of life.
Aims: (1) to Establish the FLS services at the National Taiwan University Hospital Jinshan Branch. (2) To establish a anti-osteoporosis medication management service at Jinshan Branch. Method: From Aug., 2015, a fracture liaison services (FLSs) following the 13 'Capture the Fracture Best Practice Standards' were implemented at the National Taiwan University Hospital Jinshan Branch health care system. The Jinshan Branch program enrolled patient with 1) new hip fracture 2) newly identified vertebral fractures (radiological or clinical) from both inpatients and outpatients. At the same time, a osteoporosis medication management service is also establish as a complement of FLS to enroll patients on antiosteoporosis medications (AOMs) but not necessary with fracture. Participating physicians will select those eligible for services and refer to study coordinators. Study coordinators will conduct baseline assessments on osteoporosis/fracture risks, record medical conditions, AOMs, provide educations on osteoporosis, fracture, sarcopenia, fall, medications, nutrition, and exercise. They also arrange return clinic visit, telephone reminder and follow up for patients, and communicate with providers on regular bases. During the whole study period, the investigators planed to enroll 200 patients (with or without fracture). Each patient would be assessed at baseline, and every 4 months last for two years.
The aim of this study is to acquire preliminary, pilot data over a 2-year period on the safety and efficacy of subcutaneous denosumab versus the current CHEO standard-of-care (intravenous zoledronic acid) for the treatment of osteoporosis in children. Both denosumab (1.0mg/kg) and zoledronic acid (0.025mg/kg) will be given as four doses separated by a six month interval (i.e. at baseline, 6 months, 12 months and 18 months), with follow-up to 2 years.
This study explores the effect of zoledronic acid on incident vertebral fractures and osteonecrotic lesions in children recently diagnosed with acute lymphoblastic leukemia.
This study uses a bone labeling calcium tracer methodology to compare the dose-response effect of blueberry consumption on calcium retention and bone loss. Post-menopausal women will receive food or beverage products containing freeze-dried blueberries in the amount equivalent to 0.75 (low), 1.5 (medium), and 3 cups (high) of fresh blueberries per day over a 42-day period. The hypothesis is that the polyphenolics found in blueberries will reduce calcium loss from bones.
