Introduction: One of the challenges of personalized medicine is a departure from traditional pharmacology toward individualized, genotype-based therapies. Postmenopausal osteoporosis is a prevalent condition requiring intensive treatment, whose effects are measurable only after a long time, and the goal is bone fracture prevention. This study aimed to determine the influence of gene variation on anti-osteoporotic one-year treatment with denosumab in 63 Polish women with postmenopausal osteoporosis.

Materials And Methods: The correlation between bone mineral density (BMD) of the lumbar vertebral column (L1-L4) and femoral neck, and genotype distributions for the , , , and variants of the gene was analyzed. Bone fractures during denosumab therapy were also investigated.

Results: In the case of the polymorphism, female patients with BB and Bb genotypes had statistically significantly higher values of BMD and T-score/Z-score indicators, which persisted after a year of denosumab treatment. Our results indicated that the polymorphism contributes to better bone status, and, consequently, to more efficient biological therapy. The study did not reveal significant differences between changes (delta) in BMD and genotypes for the analyzed gene . In the entire study group, one bone fracture was observed in one patient throughout the yearlong period of denosumab therapy.

Conclusions: BB and Bb genotypes of the polymorphism of the gene determine higher DXA parameter values both before and after one-year denosumab therapy in postmenopausal women with osteoporosis.

Background: The increasing prevalence of glucocorticoid-induced osteoporosis (GIOP) due to long-term glucocorticoid therapy underscores the need for effective treatment options. Denosumab and bisphosphonates, both key in managing GIOP, require further comparative evaluation to determine their relative efficacy and safety profiles.

Methods: We conducted a systematic review and meta-analysis, adhering to PRISMA guidelines.

Patient-derived tumor organoids (PDTOs) models have been widely used to investigate the response of primary cancer tissues to anti-cancer agents. Nonetheless, only few case study tried to establish PDTOs and test treatment response based on bone metastasis (BoM) tissues. Fresh BoM tissues were obtained from lung cancer (LC) patients who underwent spinal metastatic tumor surgery for PDTOs culture.

Bone Health ECHO (Extension for Community Healthcare Outcomes) is a virtual community of practice, where healthcare professionals have met via videoconferencing weekly since 2015. This model of learning is focused on short didactics and the presentation of real but de-identified patient cases followed by highly interactive discussions. These are often clinical situations with diagnostic and therapeutic dilemmas that are not readily addressed by randomized placebo-controlled clinical trials and clinical practice guidelines.

Tenosynovial giant cell tumor (TGCT) is a fibrous histiocytic tumor originating in the synovial membrane. While cervical TGCT may not be considered a common diagnosis preoperatively because it is relatively rare, it has a high recurrence rate and should be considered. Total resection is preferable, but it can be challenging due to the risk of damaging the vertebral artery.
