Proton pump inhibitors (PPIs) are among the most used drugs in the UK. PPI use has been associated with decreased bone mineral density (BMD) and increased fracture risk, although these results have been inconsistent. We hypothesized that PPI could modulate BMD by altering gut and/or host systemic metabolic environments. Using data from more than 5000 British male and female individuals, we confirmed that PPI use is associated with decreased lumbar spine and total hip BMD. This effect was not mediated through the gut microbiome. We suggest here that PPI use may influence total hip BMD, both directly and indirectly, via plasma metabolites involved in the sex hormone pathway. © 2022 The Authors.

Objective: Progesterone (PG) and its target, progesterone receptor (PGR), are important regulators in inflammatory diseases. This study aimed to investigate the specific role of PG in periodontitis and to elucidate the underlying mechanisms involving PGR.
Methods: Women with periodontitis, including 250 with PG deficiency, 250 with PG supplementation, and 245 controls (normal PG) were enrolled.

Background: Hounsfield units (HU) on computed tomography (CT) are strongly correlated with bone mineral density (BMD) and may aid in osteoporosis screening. However, there is no standardized method for assessing bone density in displaced femoral head fractures. This study aimed to measure HU values in the femoral head using preoperative post-fracture CT images of patients with intertrochanteric femoral fractures and investigate whether it correlated with BMD measured by dual-energy X-ray absorptiometry (DXA).

Within the bone microenvironment, the intricate interplay and regulation among matrix components form a complex network. Disentangling this network is crucial for uncovering potential therapeutic targets in bone pathology. Osteocalcin (OCN), the most abundant non-collagenous bone protein, is an essential node within this network.

Atypical proximal tibial fractures in adolescents are rare, particularly when linked to hormonal therapy for short stature. This case series reports the clinical and imaging features of atypical proximal tibial and distal femoral physeal fractures in male adolescents undergoing combined growth hormone (GH) and aromatase inhibitor (AI) therapy for idiopathic short stature. We report three cases of skeletally immature male adolescents (ages 12-16) treated with GH and anastrozole who presented with acute leg pain following low-energy trauma during soccer.

Unlabelled: REMS-BMD by radiofrequency echographic multispectrometry is primarily determined by a patient's BMI, age, and sex. Only about 2.8% of the changes in femoral neck REMS-BMD can be attributed to replacement of the total hip with metal implants.
