Quantitating Age-Related BMD Textural Variation from DXA Region-Free-Analysis: A Study of Hip Fracture Prediction in Three Cohorts.

J Bone Miner Res 2022 Jun 24. Epub 2022 Jun 24.

Department of Oncology and Metabolism, The University of Sheffield, Sheffield, S10 2RX, U.K.

The risk of osteoporotic fracture is inversely related to bone mineral density (BMD), but how spatial BMD pattern influences fracture risk remains incompletely understood. This study used a pixel-level spatio-temporal atlas of proximal femoral BMD in 13,338 white European women (age 20 to 97 years) to quantitate age-related texture variation in BMD maps and generate a 'reference' map of bone ageing. We introduce a new index, called Densitometric Bone Age (DBA), as the age at which an individual site-specific BMD map (the proximal femur is studied here) best matches the median ageing trajectory at that site in terms of the root mean squared error (RMSE).

Acta Endocrinol (Buchar) 2021 Oct-Dec;17(4):509-516

"Iuliu Hațieganu" University of Medicine and Pharmacy, 2 Internal Medicine Department, Cluj-Napoca, Romania.

Recent studies suggest that osteopontin (OPN) could be used as an early marker for the diagnosis of bone disorders. Considering the contradictory opinions in the literature, the objective of this systematic review is to analyse the current information regarding the relationship between OPN and bone mineral density (BMD), which represents an important process in the development of osteoporosis. We performed a literature search of clinical trials using the PubMed database, published between 1999-2020, and identified 7 studies that were eligible for analysis. Read More

Nutrients 2022 Jun 15;14(12). Epub 2022 Jun 15.

Department of Medicine and Therapeutics, Prince of Wales Hospital, The Chinese University of Hong Kong, Hong Kong 999077, China.

Amino acids (AAs) and dietary inflammatory potential play essential roles in muscle health. We examined the associations of dietary inflammatory index (DII) of habitual diet with serum AA profile, and ascertained if the associations between DII and muscle outcomes were mediated by serum AAs, in 2994 older Chinese community-dwelling men and women (mean age 72 years) in Hong Kong. Higher serum branched chain AAs (BCAAs), aromatic AAs and total glutathione (tGSH) were generally associated with better muscle status at baseline. Read More

Cardiovascular Safety and Effectiveness of Bisphosphonates: From Intervention Trials to Real-Life Data.

Nutrients 2022 Jun 7;14(12). Epub 2022 Jun 7.

Bone Metabolic Diseases Unit, Department of Experimental, Clinical and Biomedical Sciences, University of Florence, 50139 Florence, Italy.

Both osteoporosis with related fragility fractures and cardiovascular diseases are rapidly outspreading worldwide. Since they are often coexistent in elderly patients and may be related to possible common pathogenetic mechanisms, the possible reciprocal effects of drugs employed to treat these diseases have to be considered in clinical practice. Bisphosphonates, the agents most largely employed to decrease bone fragility, have been shown to be overall safe with respect to cardiovascular diseases and even capable of reducing cardiovascular morbidity in some settings, as mainly shown by real life studies.

Association of the rs700518 Polymorphism with Selected Markers of Bone Metabolism in Women with Hyperandrogenism.

J Clin Med 2022 Jun 20;11(12). Epub 2022 Jun 20.

Department of Pharmacology and Pharmacoeconomics, Pomeranian Medical University, 71-230 Szczecin, Poland.

Hyperandrogenism is the most common endocrine disorder in women, characterized by an imbalance of normal estrogen and androgen levels in the blood. Androgens play an important role in the female body because they influence bone mineral density (BMD), body mass composition, muscle mass, mental state, and the regulation of sexual function. The reduced activity of aromatase, due to mutations in the gene, reduces the estrogen pool in favor of androgens. Read More
