The Effect of Bovine Colostrum Supplementation in Older Adults
SarcopeniaOsteoporosisBovine colostrum is the initial milk secreted by cows during the first day after calving. Colostrum is high in protein and contains a number of substances that have potential to be beneficial for the immune system. Preliminary studies about effects of colostrum supplementation show its potential for increasing human exercise performance; however, more evidence across the lifespan is required to confirm effects and to understand mechanisms of action. The objectives are to determine the effect of 8 weeks of bovine colostrum supplementation, compared to whey protein supplementation on the following dependent variables in men and women 50 years and older while participating in a resistance-training program: muscle mass strength blood levels of growth factors and markers of inflammation urine levels of muscle and bone catabolic markers tests of cognitive ability It is hypothesized that bovine colostrum supplementation will result in greater increases in muscle mass, strength, blood IGF-1 levels (an anabolic hormone), and cognitive ability, and greater reductions in inflammation, and markers of muscle and bone catabolism, compared to placebo.
Sarcopenia and Risk of Falls in Patients With Major Chronic Diseases
StrokeOsteoporosis2 moreThe objective of this study is to investigate the effects of therapeutic exercise and nutrition intervention for sarcopenia and risk of falls in patients with major chronic diseases. The outcomes will be analyzed regarding muscle strength, quality, and volume, etc., balance and gait, bone density, body composition, fall and quality of life after the intervention.
Blackcurrants Modify Gut Microbiota and Reduce Osteoporosis and CVD Risk
Postmenopausal OsteoporosisGut Microbiota1 moreAim to evaluate the effects of blackcurrant supplementation on changes in gut microbiome, bone mass, and CVD risk factors in adult women.
Improving Bone Health Among Rheumatoid Arthritis (RA) Patients on Chronic Glucocorticoids
Adverse Effect of Glucocorticoids and Synthetic AnaloguesOsteoporosis1 moreThis quality improvement project is aimed at improving health care by identifying low cost strategies to get Rheumatoid Arthritis (RA) patients to more effectively communicate with their physicians about osteoporosis prevention and treatment (improving doctor-patient communication). The investigators will implement a direct to patient intervention to the population of interest (patients on chronic glucocorticoids) via story-telling, using an Internet based video. The target audience is people on chronic glucocorticoids not already receiving bones-specific osteoporosis medications to determine differences in post-intervention rates of osteoporosis care, and the rates of prescription anti-osteoporosis therapies.

Rheumatoid ArthritisOsteoporosis1 moreThis study was to investigate the efficacy of oral monthly ibandronate in the management of glucocorticoid induced osteoporosis in women with rheumatoid arthritis.
Musculoskeletal Effects of Bicarbonate
Muscle LossFractures3 moreWith aging, men and women develop a mild and progressive metabolic acidosis. This occurs as a result of declining renal function and ingestion of acid-producing diets. There is extensive evidence that severe metabolic acidosis causes bone and muscle loss, but the impact of the chronic, mild acidosis on bone and muscle in older individuals has not been established. In a recent study, administration of a single dose of bicarbonate daily for 3 months significantly reduced urinary excretion of N-telopeptide (NTX), a marker of bone resorption and urinary nitrogen, a marker of muscle wasting and improved muscle performance in the women but not the men. These and other data support a potential role for bicarbonate as a means of reducing the musculoskeletal declines that lead to extensive morbidity and mortality in the elderly. Before proceeding to a long-term bicarbonate intervention study, however, it is important to identify the dose of bicarbonate most likely to be optimal and to characterize the subjects who benefit most from it. This double blind, placebo controlled, dose-finding study will evaluate the effects of placebo and two doses of bicarbonate on urinary NTX and nitrogen excretion and on lower extremity performance over a 3 month period in 138 men and 138 women, age 60 and older. Changes in urinary excretion of NTX and nitrogen and in selected measures of lower extremity performance will be compared across the three groups. The safety and tolerability of the interventions will also be evaluated. This investigation should provide needed information on the appropriate dosing regimen for men and women and on the study population that should be enrolled in a future bicarbonate intervention trial to assess the long-term effects of this simple, low cost intervention on important clinical outcomes including rates of loss in bone and muscle mass, falls, and fractures.
Nitrates and Bone Turnover; Nitrates and Bone Turnover Bisphosphonate Sub-Study
OsteoporosisPurpose: NABT: To compare five widely available nitrate formulations: (1) 15 of nitroglycerin (NTG) ointment, (2) 0.3 mg and (3) 0.6 mg of sublingual NTG, (4) 20 mg of isosorbide mononitrate (an oral tablet), and (5) 160 mg of glycerol trinitrate (a patch), for their efficacy on markers of bone formation and resorption and for the incidence and severity of headache they cause. Hypothesis: There is one ideal nitrate preparation which balances the clinical efficacy in bone remodeling against the common side effect of headache. NABT-B: To determine if nitrates affect markers of bone formation (serum BALP and P1NP) and resorption (serum CTX and urine NTX) in women who have recently discontinued treatment with alendronate, risedronate or zoledronate.
