The Impact of Smoking on Bone Metabolism, Bone Mineral Density and Vertebral Fractures in Postmenopausal Women.

Background: Smoking is recognized among the risk factors for osteoporosis, but only few studies have comprehensively explored its influence on bone metabolism and strength. We aimed to evaluate smoking effects on calcium-phosphate metabolism, bone mineral density (BMD) and fracture risk in postmenopausal women.

Methods: Our sample included 1067 postmenopausal women who arrived to our osteoporosis outpatient clinic.

Identification of asymptomatic frailty vertebral fractures in post-menopausal women.

Purpose: Vertebral fractures are associated with persistent pain, disability and mortality. However, around two thirds of women with vertebral fractures are unaware of them. We aimed to analyze which factors could mostly be associated to the presence of vertebral fractures in post-menopausal women, and evaluate the effectiveness of current screening criteria for the detection of vertebral fractures in an outpatient setting.

The Association Between Bone Mineral Density and Airflow Limitation in a Cohort of Fit Elderly Women.

Purpose: As studies examining the association between bone mineral density (BMD) and airflow limitation (AL) have produced conflicting results, the current one set out to analyze if and to what degree there are any correlations between these variables in a population of fit elderly women.

Methods: One hundred and twenty-one non-smoking, fit and healthy women (age ≥ 65 years) underwent anthropometric assessment, laboratory testing (serum 25-hydroxy vitamin D, parathormone, and cytokine levels), pulmonary function testing (PFT), and dual-energy X-ray absorptiometry to evaluate BMD values of the lumbar and femoral regions.

Results: A significant positive association was found between FEV/FVC ratio (Tiffeneau index), a sensitive index of AL, and lumbar and femoral BMD; a 10 % increase in the FEV/FVC ratio resulted in a significant increase of 0.

Nephrolithiasis, bone mineral density, osteoporosis, and fractures: a systematic review and comparative meta-analysis.

Unlabelled: Our meta-analysis demonstrates that people with nephrolithiasis have decreased bone mineral density, an increased odds of osteoporosis, and potentially an elevated risk of fractures.

Introduction: People with nephrolithiasis might be at risk of reduced bone mineral density (BMD) and fractures, but the data is equivocal. We conducted a meta-analysis to investigate if patients with nephrolithiasis have worse bone health outcomes (BMD), osteoporosis, and fractures versus healthy controls (HCs).

Duration of breastfeeding as a risk factor for vertebral fractures.

Purpose: Among the risk factors for osteoporosis and fractures, gynecological history (fertile period, parity and breastfeeding) play an important part. Changes in calcium metabolism to enable an adequate mineral transfer to the milk have a prominent role in bone loss during breastfeeding. Data on the influence of breastfeeding in postmenopausal osteoporosis are inconsistent.

Effects of acetylsalicylic acid and indomethacin on growth hormone secretion in man.

To investigate the possibility that prostaglandins (PG) take part in the control of growth hormone (GH) secretion in humans, we have studied the effects of protracted and acute administration of acetylsalicylic acid (ASA) and indomethacin (ID), two PG synthesis inhibitors, on basal and insulin-stimulated GH secretion in normal volunteers. In eight subjects, oral administration of 3-2 g daily of ASA for 4 days clearly reached GH response to insulin hypoglycemia (p less than 0.01, ANOVA).
