Filter by:The overall objective of this study is to define an effective therapeutic approach, using currently available medication, to prevent or mitigate the loss of bone mass and bone strength that occurs after acute spinal cord injury.
The purpose of this study is to test whether active vitamin D (calcitriol) protects bones from weakening and protects blood vessels from calcium deposits over the first year of kidney transplantation.
The purpose of this study is to determine if a year of alendronate treatment will maintain or increase bone mass density (BMD) compared to baseline BMD values in people with chronic spinal cord injury (SCI). This study will also investigate 1) if alendronate therapy will increase bone strength in people with chronic SCI, 2) the number of participants with adverse events from alendronate, and 3) the effects of alendronate on serum markers of bone metabolism.
The purpose of this study is to determine if a second year of exposure to teriparatide in both subjects that received a year of teriparatide or teriparatide-placebo will result in a greater increase in bone mass density (BMD) compared to that seen in a single year's treatment. This study will also investigate 1) if a second year of teriparatide therapy will increase bone strength in people with chronic spinal cord injury (SCI) who previously received a year of teriparatide or teriparatide-placebo, 2) the number of participants with adverse events from teriparatide, and 3) the effects of teriparatide on serum markers of bone metabolism.
In patients that require a dental implant, does zirconia compared to titanium, or cad-cam acrylic abutments, provide less inflammation, marginal bone loss or infection during the osseointegration period ?
The purpose of the present research is to evaluate the effect of bioactive glass in bone regeneration immediately following extraction of mandibular and maxillary premolars.The hypothesis of the study assumes that this treatment would promote the healing of the extraction socket while preserving both the height and width of the bone. Furthermore, it would allow more effective tooth movement during orthodontic treatment.
The overall purpose is to explore the link between the gut and the bones by investigating meal stimulated changes in the blood level of a number of hormones and markers related to intestinal growth and bone turnover in patients undergoing surgery for obesity (gastric bypass). The hormones will be measured in blood samples taken before and after surgery. The results are compared with changes in body weight and body composition as measured by DEXA scanning.
Objective: The purpose of this study is to determine the etiology of the weight increase in Depot-medroxyprogesterone Acetate (DMPA) users. Method: Prospective study with 100 women, aged 18-40 years old and BMI < 30kg/m², paired with users of a non hormonal method follow for two years. Will be included only women who never used DMPA. There will be evaluated habit, blood pressure, anthropometric measure, distribution of corporal fat, lipids profile and glycemia parameters every six months. Thirty women and their control group will performed a euglycemic-hyperinsulinemic clamp to evaluate the resistance of insulin, adiponectin,neuropeptide Y, apolipoprotein A/B and arterial evaluation with ultrasound, intimal and media measure. Anova analysis for repeated samples. The metabolic alterations should elucidate the etiology, and the beginning of the sub clinical cardiovascular disease should be shown/discarded with the arterial evaluation.
Does the consumption of dairy foods reduce the rate of bone loss in older women more than calcium and vitamin D supplements.
Military personnel face many physiological challenges, including sustained physical activity and prolonged periods of negative energy balance. Chronic energy deficiency often results in a loss of skeletal muscle mass and can reduce overall bone health. Recent evidence suggests that dietary interventions that provide protein in excess of the current national dietary recommendation may confer protection against the negative effects of energy deficiency on the musculoskeletal system. The primary objective of this randomized, controlled study is to assess the effects dietary protein intake spanning the current acceptable macronutrient distribution range on musculoskeletal health following prolonged energy deficiency. Findings from this investigation will improve current understanding of dietary conditions necessary to reduce the damaging effects of caloric deficiency on musculoskeletal health in warfighters. Furthermore, given the rise in obesity in military populations, findings may aid in the development of nutritional weight management strategies that promote healthy weight loss without compromising musculoskeletal health.
