Filter by:According to the World Health Organization criteria, osteoporosis was defined as a bone mineral density that lies 2.5 standard deviations or more below the average value for young healthy women. Osteoporosis is a major cause of fractures and can lead to serious complications in postmenopausal women. For this reason, approaches to prevent the appearance and progression of osteoporosis are of primary importance. This randomized clinical trial analyzes the effects of two types of physical exercise oriented to prevent osteoporosis in postmenopausal women with pharmacological supplements of Calcium and Vitamin-D.
The purpose of this study is to determine wheather the monitored vitamin D (vit D) therapy is safer and more effective than standard therapy in pretrem infants.
The primary objective was to determine whether caffeine therapy is associated with decreases bone mineral content using dual energy x-ray absorptiometry. Secondary objectives were to determine whether caffeine therapy is associated with increased incidence of nephrocalcinosis or bone fracture.
The purpose of this study is to determine the effects of Moringa Oleifera on the structure and function of bone in post-menopausal women ingesting 1000 mg of Moringa Oleifera daily for 12 weeks.
To evaluate in patients with chronic kidney disease the impact of two dosages of per os vitamin D3 supplementation (cholecalciferol) on large arterial stiffness (evaluated non invasively by pulse wave velocity and high-resolution echotracking system). We will also study arterial calcification (lateral abdominal radiography and echocardiogram), arterial remodeling (high-resolution echotracking system), endothelial function (evaluated by a non-invasive finger biosensor device), and bone remodeling (evaluated by serum biomarkers and bone mineral density).
Low bone mineral density (BMD) is commonly reported in patients receiving home parenteral nutrition (HPN). Denosumab represent a new drug, which helped to prevent osteoclast. The aim of the study was to assess its value in chronic intestinal failure patients.
Despite being effective in weight reduction in severely obese patients, bariatric surgery (BS) negatively influences bone metabolism and increases the risk of falls thereby potentially increasing the risk of fracture. The mechanisms of BS induced bone loss are unknown but may be related to calcium and vitamin D malabsorption, changes in the energy regulation metabolism and gastrointestinal hormonal physiology. Since the etiology of BS induced bone loss is largely unknown, treatment relies mostly on calcium and vitamin D supplementation, which provide little benefit. Exercise is an effective strategy to prevent bone mass losses in several health conditions. However, no study so far has examined the effects of an exercise-training program in the prevention of BS induced bone loss. The investigators main goal is to investigate the effects on bone metabolism and fracture risk of an exercise-training program specifically tailored to improve bone health and balance of patients that underwent BS. The investigators will perform a randomized controlled trial on obese patients (n=80; BMI>40 Kg.m-2) elected to BS. Patients will be randomly assigned into 2 groups i) a group receiving standard follow-up and medical care, or ii) a group that will undergo a 11 months' Exercise Training program designed to improve bone health and reduce fall risk plus the standard follow-up and medical care. All patients will be assessed i) before the surgery, ii) one month, iii) 6 months, and iv) 12 months after the surgery. Assessments include: biochemical markers of bone turnover (BTM), BMD, bone tissue biomechanical properties, hormones involved in the regulation of energy, gastrointestinal and bone metabolism, body composition, BMI, nutritional intake, balance, muscle strength, cardiorespiratory fitness and daily physical activity. These evaluations will allow the investigators to understand the effects of an exercise-training program on bone metabolism of BS patients, contributing also to further elucidate the mechanisms underlying BS induced bone loss and fracture risk increase. The investigators will use established methods in the literature as well as novel procedures, which will enable them to overcome some of the limitations of previous studies. At the end of the study the investigators expect to have collected consistent data about whether an exercise-training program is or is not able to effectively prevent BS induced bone losses and fracture risk increases.
Gaucher disease is a most common genetic metabolic disease characterized by low platelet number, liver and spleen enlargement and various forms of bone diseases including low bone mineral density leading to brittle bones. Various treatment options are now available for this disease. The purpose of this research study is to determine the prevalence of Gaucher disease in patients with low bone mineral density as observed by DEXA scan, which is a form of X-Ray of the bone.
Background: Endocrine glands give off hormones. Researchers want to learn more about the disorders that affect these glands in children. These disorders might be caused by changes in genes. Genes contain DNA, which is the blueprint of how a cell works. Researchers want to identify the genes involved in endocrine and metabolic disorders. This might help develop new ways to diagnose and treat the disorders. Objective: To study the inheritance of endocrine or metabolism disorders. Eligibility: Children ages 3month-18 with known or suspected endocrine or metabolism disorders. Family members ages 3months-100. They may participate in the DNA part of the study. Design: Participants will be screened with a review of their medical records. Their parents or guardians will allow the records to be released. Participants will have a clinic visit. This may include a physical exam and medical history. Parents or guardians will give their consent for the study. Participants may have tests, surgery, or other procedures to help diagnose or treat their condition. These could include: Blood, urine, and saliva tests Growth hormone test Pituitary and adrenal function tests Picture of chromosomes Imaging tests. These may include X-ray, ultrasound, scans, or a skeletal survey. Genetic tests Sleep study Medical photographs If surgery is done, a tissue sample will be taken. Participants may have follow-up visits for diagnosis and treatment. Participating relatives will have one visit. This will include medical history and blood and saliva tests. The blood and saliva will be used for DNA testing.
Recently, osteoporosis has been recognized as a serious health problem in the elderly, it has also increased in young • middle-aged layer. Ginseng is history 2, 000 years Korean typical herbal medicine which is used as a medicinal is known the mystery of Elixir from a long time ago. A previous study was administered ginseng extract results in animal models induced osteoporosis, the bone-related biomarkers, including improved bone density and bone mass.
