Filter by:This study will compare and assess the prevalence of osteopenia and vitamin D deficiency as well as effects of TDF on the patients' bone among HIV positive and negative patients.
The study seeks to determine the impact of assessing risk for osteoporosis in women on patient and physician behaviors through a pharmacist directed osteoporosis screening program. Women will be offered a heel ultrasound to screen for their bone density and may or may not be asked questions about their risk for bone fracture. Pharmacists will counsel and educate all women on ways to prevent the onset of osteoporosis. Women will be telephoned three months after the screening and asked a series of 10 questions to follow up on decisions made by their physicians or changes made to their health behaviors related to bone health.
The aim of clinical study is to assess effectiveness of Bone UltraSonic Scanner (BUSS) versus densitometry (DXA) in osteoporosis detection.
This study is designed to provide information on the safety, tolerability, pharmacokinetics (PK) and bone biomarker response following multiple BPS804 administration in multiple dosing regimens. This information will permit a comparison of the possible risks and benefits of different dosing regimens of the study drug to enable optimal doses and dose intervals to be tested in subsequent studies.
Anorexia nervosa is an eating disorder that can cause thinning of the bones (a decrease in bone density). A significant decrease in bone density is called osteopenia or osteoporosis. Sometimes the loss of bone density can be severe enough to cause breaks and fractures of the bones. It is not known what causes the bones to thin in anorexia nervosa. Women who have this condition often have thin or weak bones that are more likely to break. They also have very low levels of a chemical called IGF-1 in their body. This chemical is very important for increasing bone growth in puberty and for maintaining healthy adult bones. The investigators would like to find out if giving rhIGF-1 followed by risedronate or risedronate alone can lead to an increase in bone formation, bone density, and bone strength in women with anorexia nervosa.
Does the consumption of dairy foods reduce the rate of bone loss in older women more than calcium and vitamin D supplements.
An adequate calcium intake is important for bone turnover and the risk of developing osteoporosis. Yet many studies have documented that supplementation with calcium tablets are often associated with a poor compliance, therefore it is important to explore ways to better calcium influx. Calcium consumed through dairy products must first be cleaved from the molecules which it is bound to before it can be absorbed. Chymosin is an enzyme which cleaves the protein binding between some amino acids in κ-casein. The reaction occurs after ingestion of milk and causes a process whereby the time the milk is staying gastrointestinal tract is extended, this can lead to enhanced uptake of calcium. When the body's calcium balance is in equilibrium excretion in urine (24 h) in roughly the size of the intake, whereby a measurement of circadian urine excretion of calcium can determine the amount of calcium absorbed from the intestine. The investigators want to clarify whether the addition of chymosin to milk increases calcium absorption. Secondary to explore issues of significance for this effect, including vitamin D status and amount of daily calcium intake and whether a change in calcium absorption has immediate effects on bone turnover (measured as plasma osteocalcin, bone specific alkaline phosphatase (BSAP), and the renal excretion of cross-linked N-terminal telopeptide of type 1 collagen (NTx/Cr) ratio) and on the parathyroid function (measured as PTH). Finally we will explore relations between bone mineral density (BMD) and the measured parameters (in terms of P-PTH, P-25OHD, P-1,25(OH)2D, P-osteocalcin, P-BSAP, and U-NTx/Cr).
The aim of this study is to investigate effect of whole-body vibration on plasma sclerostin level in healthy young adult women. Fifteen healthy young adult women are planned to include in this study. All cases will be trained on a whole-body vibration (WBV) platform (Power Plate) 5 times a week for one week period. Training duration will be short at the beginning but progressed slowly. The amplitude of vibration will be 2 mm and the frequency of the vibration will be 40 Hz. The subjects will be asked to report negative side effects or adverse reactions in their training diary. Previbration and postvibration (just after, 10.minute and 30.minute) levels of plasma sclerostin will be measured on first, second and fifth day of experiment. Sclerostin levels will be measured by human sclerostin ELISA kit.
Although there is some evidence that whole body electromyostimulation(WB-EMS) affect bone via its acute and longitudinal effects on muscle mass and strength, the corresponding impact on bone density and falls in older adults has not been assessed yet. The investigators hypothesize that WB-EMS significantly affects bone parameters as assessed by DXA, and significantly reduce fall rate and ratio in a cohort of frail elderly women.
The purpose of this study is to determine the safety and tolerability of RN564 in women with osteopenia and healthy men.
