Background: Over the last several decades, as a result of an evolution in manufacturing processes, a marked development has been made in the field of gonadotropins for ovarian stimulation. Initially, therapeutic gonadotropins were produced from a simple process of urine extraction and purification; now they are produced via a complex system involving recombinant technology, which yields gonadotropins with high levels of purity, quality, and consistency.
A total of 72 postmenopausal patients presenting no risk factors for cardiovascular disease nor osteoporosis, were studied. The study evaluated total serum cholesterol and fractions and bone mass by densitometry of the lumbar spine and femur using a Lunar-DPX. There was no association between lipid profile variables and bone mineral density, except for high density lipoprotein (HDL), which showed an inverse correlation (p=0.001). Multiple regression showed that total cholesterol levels higher than 240 mg% had a positive association with BMD (p=0.026). In addition, the ratio between LDL and HDL (Castelli 2 index) showed a negative association with BMD (p=0.002). The diagnostic validation test showed that all lipid profile variables had low sensitivity and specificity as indicators for osteoporosis. The conclusions were that lipid profile variables did not show a significant association with bone mass and could not be used as indicators for bone mineral density.
A osteoporose é doença crônico-degenerativa caracterizada pela diminuição da massa óssea e deterioração da microarquitetura do tecido ósseo, tendo como conseqüência elevado risco de fratura 1. É considerada a doença osteo-metabólica mais A Ligadura Tubária é Fator de Risco para a Redução da Densidade Mineral Óssea em Mulheres na Pós-menopausa?
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
