Active clinical trials for "Osteoporosis"

The purpose of the study is to provide information about the rate of response and persistence to drug therapies for osteoporosis. Another issue examined in this study refers to the preferences and concerns about future treatments in patients during "drug holiday".

Osteoporosis after gastrectomy, which is characterized by both the loss of bone mass and the deterioration of bone architecture, is a serious complication in the long course after gastrectomy. The aim of the present study was to evaluate osteoporosis by using high-resolution peripheral quantitative computed tomography (HR-pQCT) in the long course after gastrectomy. In total gastrectomy and distal gastrectomy groups, at least 5 years should have elapsed since gastrectomy.

Compare the data obtained with two formulations of alendronate 70 mg (tablets vs effervescent tablet for buffered solution) on the change in bone turnover markers, on gastric tolerance and on treatment adherence (including compliance and persistence).

A novel methodology was recently developed and validated by the applicants to compute bone strength at the distal radius and tibia using second-generation HR-pQCT reconstructions. The methodology is expected to improve significantly the assessment of bone fracture risk in idiopathic and secondary osteoporosis, but no reference data and no reproducibility data are available. The objective of the study is the determination of the sex- and age-specific distributions of accurate distal radius and tibia strength assessed by HR-pQCT in the Swiss population.

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 a prospective,observational single-center study. The osteoporotic patients requiring posterior lumbar interbody fusion(PLIF) with cages at the lowest fusion segment are prospectively enrolled and followed up. The patients undergoing PLIF with the 3D-printed porous titanium alloy cages are compared with those using PEEK cages. The hypothesis is that the use of 3D-printed porous titanium alloy cages can reduce the rate of pedicle screw loosening and increase the rate of lumbar fusion in osteoporotic patients.

Type 1 diabetes is associated with low bone mineral density(BMD) and type 2 diabetes with normal or high BMD. Cystatin C is a small molecule that is used to measure kidney function but it's not a troponin of the kidney. It has been associated with many other diseases like atrial fibrillation, depressive symptoms, melanoma, etc. This crossectional clinical study was done to evaluate the association between Cystatin C and Bone mineral density in both types of diabetic patients.

Studying the current state of the clinical approaches to bone diseases in breast cancer patients treated with adjuvant and/or hormone therapy

The study is a genetic historical cohort study in a military combat recruits - this study does not examine a specific treatment but rather examines a statistical link between medical history of traumatic fractures, clinical diagnosis of stress fractures and the presence of unique SNPs in subjects DNA.
