Journal ArticleDOI
The effect of low-dose continuous estrogen and progesterone therapy with calcium and vitamin D on bone in elderly women. A randomized, controlled trial.
TL;DR: The primary hypothesis was that continuous administration of conjugated equine estrogen, 0.3 mg/d, combined with medroxyprogesterone, 2.5 mg/D, in elderly postmenopausal women would prevent bone loss in the spine over 3.5 years compared with placebo in the context of adequate calcium and vitamin D nutrition.
Journal ArticleDOI

TL;DR: The lowest 25(OH)D levels are associated with an increased risk for suicide, and future studies could determine if additional sunlight exposure and vitamin D supplementation might reduce suicide by increasing 25( OH) D levels.
Journal ArticleDOI
Effect of Low-Dose Continuous Estrogen and Progesterone Therapy with Calcium and Vitamin D on Bone in Elderly Women
TL;DR: In elderly women, continuous low-dose hormone replacement therapy with conjugated equine estrogen and oral medroxyprogesterone combined with adequate calcium and vitamin D provides a bone-sparing therapy in elderly women.
Journal ArticleDOI
Comparison of speed of sound ultrasound with single photon absorptiometry for determining fracture odds ratios
TL;DR: It is concluded that ultrasound velocity is as good as single photon absorptiometry in estimating odds of fracture, and the ultrasound measure is more precise than bone mineral density, but less precise thanBone mineral content.
Journal ArticleDOI
Calcium Absorption from Three Salts and CaSO4-Fortified Bread in Premenopausal Women
TL;DR: Fractional calcium absorption was slightly but significantly greater from fortified bread than from milk (mean within subject difference = 0.0675 +/- 0.016).
