Interestingly, loading at 2 or 4 Hz was found to overcome the mechanosensing deficits observed at 0.5 Hz and these counter effects became more pronounced at 4 Hz and with sparser PCM in the lactating bone. Synergistically, higher loading frequency (2, 4 Hz) and sparser PCM enhanced flow-mediated mechanosensing and diffusion/convection of nutrients and signaling molecules for osteocytes. In summary, lactation-induced structural changes alter the local environment of osteocytes in ways that favor metabolism, mechanosensing, and post-weaning recovery of maternal bone. Thus, osteocytes play a role in balancing the metabolic and mechanical functions of female skeleton during reproduction and lactation.Chronic graft-versus-host disease (cGVHD) is a serious complication after allogeneic stem cell transplantation. There are no well-established treatment options for cGVHD after primary steroid-based treatment. Ibrutinib showed clinical benefit with an acceptable safety profile in steroid-dependent/refractory cGVHD patients in a Phase 1b/2 study (PCYC-1129-CA, NCT02195869), with which it was approved in the United States for adult cGVHD patients after failure of ≥1 systemic treatments. This open-label, single-arm, multicenter study was conducted to evaluate the efficacy, safety, pharmacokinetics, and pharmacodynamics of ibrutinib in Japanese patients ≥12 years of age with steroid-dependent/refractory cGVHD (NCT03474679). Patients were assessed on the basis of the National Institutes of Health (NIH) Consensus Development Project Criteria for Clinical Trials in cGVHD (2014). All patients received ibrutinib at a dose of 420 mg orally once daily, with a dose reduction to 280 mg/d on the concomitant use of
