Effects of whole body vibration exercises on bone mineral density of women with postmenopausal osteoporosis without medications: novel findings and literature review
Abstract
Objectives: The aim of this study was to review the literature about the effect of whole body vibration exercise in the BMD in patients with postmenopausal osteoporosis without medications. Methods: A systematic review was performed.
Results: The frequency of the mechanical vibration used in the protocols has varied from 12 to 90 Hz. The time used in the protocols varied from 2 up to 22 months. Techniques with ...

COPD and osteoporosis: links, risks, and treatment challenges
Abstract: Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory airway disease associated with various systemic comorbidities including osteoporosis. Osteoporosis and its related fractures are common and have significant impacts on quality of life and even respiratory function in patients with COPD. COPD-associated osteoporosis is however extremely undertreated. Recent studies have suggested that both decreased bone mineral density (BMD) and impaired bone quality contribute to bone fragility, causing ...

Calcium plus vitamin D supplementation and risk of fractures: an updated meta-analysis from the National Osteoporosis Foundation
Abstract
Summary The aim was to meta-analyze randomized controlled trials of calcium plus vitamin D supplementation and fracture prevention. Meta-analysis showed a significant 15 % reduced risk of total fractures (summary relative risk estimate [SRRE], 0.85; 95 % confidence interval [CI], 0.73–0.98) and a 30 % reduced risk of hip fractures (SRRE, 0.70; 95 % CI, 0.56–0.87). Introduction Calcium plus vitamin D supplementation has been widely recomme...

Associations between VDR Gene Polymorphisms and Osteoporosis Risk and Bone Mineral Density
in Postmenopausal Women: A systematic review and MetaAnalysis
Results on the relationships between vitamin D receptor (VDR) gene polymorphisms and postmenopausal osteoporosis (PMOP) susceptibility and bone mineral density (BMD) are conficting. The aim of the study is to identify more eligible studies that calculated pooled OR and WMD with 95% CI to assess their associations. Overall, there were signifcant correlations between VDR ApaI, VDR FokI and PMOP susceptibility. Subgroup analysis ...

Associations between ERα/β gene polymorphisms and osteoporosis susceptibility and bone mineral density in postmenopausal women: a systematic review and meta-analysis
Abstract
Background: Many studies have reported associations between estrogen receptor (ER) gene polymorphisms and
postmenopausal osteoporosis (PMOP) risk and bone mineral density (BMD), but the results are controversial. The
aim of the present meta-analysis is to verify the association between ERα and ERβ gene polymorphisms and
osteoporosis susceptibility and BMD in postmenopausal women.
Methods: PubMed, EMBASE, ...

ASSESSMENT OF DIFFERENCES IN NUTRIENTS CONSUMPTION IN WOMEN DIAGNOSED WITH OSTEOPOROSIS AS COMPARED TO A HEALTHY CONTROL GROUP
ABSTRACT
Background. Osteoporosis is a condition that has been much more frequent for women, which is related to menopause and to their lower bone mineral density (BMD). Inappropriate diet is among the development factors of the disease.
Objective. To assess differences in consumption of particular nutrients among women with and without osteoporosis diagnosed.
Material and Methods. The study was conducted in 2013 in a group of 100 women aged 51-70, using a ...

Vitamin D Deficiency and Metabolism in HIV-Infected and HIV-Uninfected Men in the Multicenter
AIDS Cohort Study
Abstract
We evaluated associations of serum 25-hydroxyvitamin D (25[OH]D) and 1,25-dihydroxyvitamin D (1,25[OH]2D) levels in a cohort of HIV-infected and HIV-uninfected men at risk for infection in the United States. Stored samples collected between 1999 and 2008 were tested for vitamin D metabolites between 2014 and 2015. Vitamin D deficiency was defined as a serum concentration of 25[OH]D <20 ng/ml. Multivariate models were used to assess associations of various ...

Vitamin D levels and their impact on mineral metabolism in HIV infected patients: an exploratory study
Summary
Vitamin D has immunomodulating properties. The nuclear receptor for vitamin D is expressed in several immune cells, which convert 25-hydroxyvitamin D (25OHD) to the active form 1,25 hydroxyvitamin D [1,25(OH)2 D].
Under conditions of infection, 1,25(OH)2 D promotes production of cathelicidin (an antimicrobial peptide) in
monocytes and activated macrophages. In vitro studies have shown the ability of cathelicidin to inhibit replication of human immunodeficiency virus (HIV-1) ...
