This paper reviews some recent studies on former uranium miners, shares what seems controversial to the author and wonders whether lifetime exposure at home to widely varying radon concentrations can actually impact the quality of exposure assessment, and hence impact the results of the exposure-risk relationship. This meta-analysis compared the efficacy and safety of oral anticoagulation (OAC) therapy alone versus OAC plus single antiplatelet therapy (SAPT) in patients with an indication for chronic OAC (mostly due to atrial fibrillation) after transcatheter aortic valve implantation (TAVI). A systematic literature search was performed in the PubMed, Embase, and Cochrane Library databases to identify relevant studies. Data was extracted from the eligible studies and outcomes expressed as relative risks (RRs) with 95% confidence intervals (CIs). Five studies comprising 1344 patients with an indication for chronic OAC and undergoing TAVI were included. Of the 1344 patients, 480 patients received OAC therapy alone and 864 patients received OAC plus SAPT. There were no significant differences between OAC alone versus OAC plus SAPT in all-cause mortality (RR = 1.05, 95% CI 0.84-1.30, p = 0.69) and ischemic stroke (RR = 0.95, 95% CI 0.95-1.61, p = 0.86). However, OAC alone was associated with significantly lower risks of all bleeding events (RR = 0.62, 95% CI 0.49-0.69, p < 0.0001) and major and/ life-threatening bleeding events (RR = 0.57, 95% CI 0.42-0.76, p = 0.0002) compared to OAC plus SAPT. In patients with an indication for chronic anticoagulation, post-TAVI antithrombotic therapy with OAC alone compared to OAC plus SAPT may be not significantly different in reducing all-cause mortality and ischemic stroke, but has an important benefit in a significantly lower risk of all bleeding and major and/life-threatening bleeding events. In patients with an indication for chronic anticoagulation, post-TAVI antithrombotic therapy with OAC alone compared to OAC plus SAPT may be not significantly different in reducing all-cause mortality and ischemic stroke, but has an important benefit in a significantly lower risk of all bleeding and major and/life-threatening bleeding events. The goals of this review are two folds (1) to describe the recent understandings on the roles of calcitonin gene-related peptide-α (CGRP) in bone homeostasis and the underlying mechanisms of related neuronal regulation and (2) to propose innovative CGRP-modulated approaches for enhancing bone regeneration in challenging bone disorders. CGRP is predominantly produced by the densely distributed sensory neuronal fibers in bone, declining with age. Under mechanical and biochemical stimulations, CGRP releases and exerts either physiological or pathophysiological roles. CGRP at physiological level orchestrates the communications of bone cells with cells of other lineages, affecting not only osteogenesis, osteoclastogenesis, and adipogenesis but also angiogenesis, demonstrating with pronounced anabolic effect, thus is essential for maintaining bone homeostasis, with tuned nerve-vessel-bone network. In addition, its effects on immunity and cell recruitment are also crucial for bone fracture healing. Binding to thgh-resolution 3D imaging of transparent bulk bone and single-cell RNA-sequencing. Last but not the least, given that small molecule antagonists such as BIBN4096BS can block the beneficial effects of CGRP on bone, concerns on the potential side effects of humanized CGRP-neutralizing antibodies when systemically administrated to treat migraine in clinics are arising. Osteoporosis is commonly diagnosed through the clinical assessment of bone quantity using bone mineral density; however, the primary clinical concern is bone fragility. Bone fragility is determined by both bone quantity and bone quality. Over the past decade, the gut microbiome has emerged as a factor that can regulate diseases
