Calciumis the key to keeping bones healthy. Hormone changes that happen at menopause increase the chance of having osteopenia for people AFAB, and people AMAB with lower testosterone levels have higher odds of getting it. Other risk factors include those that can lead to developing osteoporosis, ...
Mean serum GH and IGF-I levels were respectively 159 +/- 183 micrograms/l and 843 +/- 497 micrograms/l. Total body calcium was increased in the acromegalics (males: 1272 +/- 217 g, range 916-1816 g; females: 1041 +/- 223 g, range 739-1609 g) when compared with normal ...
Getting lower bone density is, in part, a natural consequence of inactivity and weak muscles and is also typical of normal women after menopause. The problem comes when this progresses from acceptable, low fracture-risk levels to high fracture-risk levels, which can lead to a hip fracture, ...
Bone formation was not increased (alkaline phosphatase and serum P1CP levels were normal). In the partially treated group, the level of P1CP was significantly increased compared to the untreated group (Mann Whitney z = 2.27, p = 0.02), suggesting that bone formation was occurring. In the ...
supplement, even at a relatively modest dose of 500 mg, produces a "borderline hypercalcemia" that persists for several hours and raises the risk for MI or stroke, the same way that people in the highest quartile for normal blood calcium levels have an increased risk for cardiovascular disease...
Osteopenia is a term to define bone density that is not normal but also not as low as osteoporosis. By definition from the World Health Organization osteopenia is defined by bone densitometry as a T score 1 to 2.5. There are many causes for osteopenia including calcium and vitamin D deficienc...
Median time of progression to osteopenia was almost 7 years, but in those patients with normal BMD but whose baseline minimum T score was in the “high-risk" tertile, this progression was much faster (<2 years). Similarly, osteopenia progressed to osteoporosis in a quarter of patients. How ...
Let’s start with a definition of terms. Osteopenia refers to a decrease in bone mineral density below normal reference values, yet not low enough to meet the diagnostic criteria for osteoporosis. Clinicians assess bone mineral density using a T score, which is a numerical value determined by ...
Spaceflight osteopenia remains one of the most serious impediments to long term exposure to microgavity. Much of the research on its cause has been focused on the absence of weigthbearing in the bones of the lower extremities.
Four normal men were injected intravenously with physiological doses (6 mug) of vitamin D(3)-1,2-(3)H. Serial samples of plasma were collected for 50 days... JE Smith,DWS Goodman - 《Journal of Clinical Investigation》 被引量: 187发表: 1971年 Dexamethasone treatment impairs calcium regulat...
