Bone Turnover Markers Predict Changes in Bone Mineral Density in Men Treated with Abaloparatide: Results from ATOM.

Early increases in bone turnover markers (BTMs) in response to anabolic therapy correlate with 18-month bone mineral density (BMD) increases in postmenopausal women with osteoporosis; however, this relationship has not been assessed in men. In this analysis, the correlation between changes from baseline in fasting intact serum procollagen type I N propeptide (PINP) and serum carboxy-terminal cross-linking telopeptide of type I collagen (CTX) at 1, 3, 6, and 12 months and percent increase from baseline in BMD at 12 months in men from the randomized phase 3 ATOM study (NCT03512262) were evaluated using Pearson's correlation coefficients. The uncoupling index (UI), a measure of the balance between markers of bone formation (PINP) and bone resorption (CTX), with positive UI favoring bone formation, was calculated.

Risk of Gastrointestinal Diseases in Osteogenesis Imperfecta: A Nationwide, Register-Based Cohort Study.

Osteogenesis imperfecta (OI) is a group of rare genetic disorders most commonly caused by reduced amount of biologically normal collagen type I, a structural component of the gastrointestinal tract and abdominal wall. The risk of gastrointestinal (GI) disease in individuals with OI is not well understood, despite GI complaints being frequently reported by the OI population. To investigate the risk of GI diseases in individuals with OI.

Cardiovascular disease in adults with osteogenesis imperfecta: Clinical characteristics, care recommendations and research priorities identified using a modified Delphi technique.

Osteogenesis imperfecta (OI) is a multisystem disorder most often caused by pathogenic variants in genes that encode type I collagen. Type I collagen is abundant not only in bone but also in multiple tissues including skin, tendons, cornea, blood vessels and heart. Thus, OI can be expected to affect cardiovascular system, and there are numerous reports of cardiovascular disease (CVD) in people with OI.

Sociodemographic, lifestyle, and medical factors associated with calculated free testosterone concentrations in men: individual participant data meta-analyses.

Objective: Sociodemographic, lifestyle, and medical variables influence total testosterone (T) and sex hormone-binding globulin (SHBG) concentrations. The relationship between these factors and "free" T remains unclear. We examined 21 sociodemographic, lifestyle, and medical predictors influencing calculated free T (cFT) in community-dwelling men across ages.

Associations of Serum Testosterone and Sex Hormone-Binding Globulin with Incident Fractures in Middle-Aged to Older Men.

Context: As men age, circulating testosterone (T) decreases, circulating sex-hormone binding globulin (SHBG) increases, and risk of fracture increases. It is unclear if circulating T, independently of comorbidities, is associated with fracture risk in men.

Objectives: To determine associations for T and SHBG with incident fractures in men.
