Effectiveness of romosozumab in patients with osteoporosis at high fracture risk: a Japanese real-world study.

Introduction: To describe the real-world use of romosozumab in Japan, we conducted a chart review of > 1000 Japanese patients with osteoporosis (OP) at high risk of fracture, across multiple medical institutions.

Materials And Methods: Treatment-naïve and prior OP-treatment patients who received romosozumab for 12 months followed by ≥ 6 months of sequential OP treatment were included. The primary objective described the baseline demographics and clinical characteristics; secondary objectives evaluated changes in bone mineral density (BMD) and bone turnover markers in all patients and effectiveness of romosozumab in a sub-group of treatment-naïve patients using the fracture risk assessment tool (FRAX).

Efficacy and safety of romosozumab among Japanese postmenopausal women with osteoporosis and mild-to-moderate chronic kidney disease.

Introduction: This post hoc analysis of the placebo-controlled phase 3 FRAME study assessed the efficacy and safety of romosozumab in a subpopulation of Japanese postmenopausal women with osteoporosis and chronic kidney disease (CKD).

Materials And Methods: Data were analyzed by baseline estimated glomerular filtration rate (eGFR), where < 90 mL/min/1.73 m denoted CKD and ≥ 90 mL/min/1.

Romosozumab followed by denosumab in Japanese women with high fracture risk in the FRAME trial.

Introduction: This post-hoc analysis of the FRAME study investigated the long-term efficacy and safety of romosozumab followed by denosumab in postmenopausal Japanese women with osteoporosis at high fracture risk.

Materials And Methods: Data from Japanese women with a high fracture risk participating in the international, randomised, double-blind, placebo-controlled, phase 3 FRAME study were analysed. High risk of fracture was defined as ≥ 1 fragility fracture with bone mineral density (BMD) ≤ - 2.

Correlation of Radiocesium Activity between Muscle and Peripheral Blood of Live Cattle Depending on Presence or Absence of Radiocontamination in Feed.

To monitor radiocesium activity in skeletal muscle of live cattle, the animals were given radiocesium-contaminated feed continuously, then switched to contamination-free feed after radiocecium concentration in peripheral blood (PB) reached plateau. Radioactivity in skeletal muscles of neck and rump was measured by attaching the probe of a NaI survey meter closely on the body surface just above the muscle of the live cattle (external measurement). We validated the strong positive correlation between the value of the external measurement and radiocesium activity concentration of dissected muscle (r = 0.
