Bone Mineral Density (BMD) is one of the primary markers of bone health. Exercise provides constant mechanical stress to bone, which in turn increases BMD. Gut-bone axis is considered to play an important role in the regulation of exercise on bone. Also, the metabolites of gut microbiota (GM), especially short-chain fatty acids (SCFAs), are thought to be involved in the progress. In this study, by analyzing serum and GM from humans with low and high BMD, we found that exercise indeed enhanced BMD, and butyrate secreted from GM was involved in the regulation.

Background: Our previous study suggested that low bone mineral density (BMD), known as osteopenia, was a poor prognostic factor in patients who underwent esophagectomy for esophageal cancer (EC).Meanwhile, the association between BMD reduction during neoadjuvant chemotherapy (NAC) and the worse prognosis remains unknown, although esophagectomy after NAC is the first option for the treatment of advanced esophageal squamous cell carcinoma (ESCC). Therefore, this study intended to investigate the prognostic impact of BMD reduction during NAC.

Background: Guided bone regeneration (GBR) relies on biocompatible membranes to support osteogenesis. 1,4-butanediol diglycidyl ether (BDDE)-crosslinked hyaluronic acid (xHyA) has shown promise in enhancing bone regeneration, yet its mechanisms remain unclear.
Objective: This study evaluates the osteogenic effects of xHyA-functionalized native pericardium collagen membrane (NPCM) and ribose-crosslinked collagen membrane (RCCM) using an airlift culture model with SaOS-2 cells.

Unlabelled: This retrospective cohort study analysed a total of 344 patients from the OSTEOMED registry with matched baseline and follow-up DXA data, finding that comorbidities such as nephrolithiasis, hypertension or coronary heart disease may influence the response to prescribed anti-osteoporotic treatment.
Purpose: To determine: 1) comorbidities associated with reduced bone mineral density (BMD), T-score and Z-score at the lumbar spine (L1 to L4 vertebrae), femoral neck and total hip; and 2) the role of multimorbidity (≥ 2 comorbidities) in reduced BMD, T-score and Z-score at the lumbar spine, femoral neck and total hip.
Methods: Retrospective cohort study analyzing patients [319 females (92.

Purpose: Conduct an overview of systematic reviews of the current fracture risk prediction tools in use.
Material And Methods: We included systematic reviews (SRs) that assessed the predictive ability of any tool, score, algorithm, or other instrument for fracture risk. The primary outcome measure was the area under the curve (AUC) representing predicted fracture risk within a specified timeframe obtained from receiver operating characteristic (ROC) analysis.
