Summary: In this study, a novel surface coating composed of zein, bioactive glass, and copper-containing bioactive glass was developed by electrophoretic deposition (EPD) to improve the bioactivity and antibacterial properties of stainless steel implants for bone replacement. The coatings exhibited excellent cytocompatibility, maintained pro-osteogenic properties towards progenitor cells, and demonstrated antibacterial activity against common joint pathogens. Additionally, the ability of copper to recruit blood vessels and inhibit bacterial infection was confirmed in vivo, enhancing the therapeutic potential of the coatings for orthopedic applications.

Summary: Effective wound management is challenging due to complexity of wound microenvironment, bacterial infections, impaired angiogenesis, aggravated inflammation, and enduring pain. A multifunctional composite hydrogel was developed to address these challenges, comprised of gelatin, chitosan, polydopamine-coated bioactive glass (BG), and curcumin-capped silver nanoparticles (Cur-AgNPs). The PDA-coated BG provides adhesive, angiogenic, and pain-relieving properties, while Cur-AgNPs offer bactericidal and anti-inflammatory benefits. The composite hydrogel showed excellent wound healing potential by alleviating pain, eliminating microbes, reducing inflammation, promoting angiogenesis, and achieving effective skin regeneration.

Summary: Self-expanding cryogels with unique properties have potential for treating uncontrollable hemorrhages. In this study, a superelastic cellular-structured bioactive glass nanofibrous cryogel (BGNC) was developed, showing high absorption capacity, fast self-expanding ability, injectability, and good tissue adhesion. The BGNCs demonstrated superior hemostatic capacity in animal models and promoted wound healing. These findings offer a promising strategy for the development of multifunctional hemostatic and wound repair materials.

Summary: This study investigates the effect of sintering temperature on bioactive glass-ceramics derived from a new composition of CaO-P2O5-Na2O-B2O3-SiO2 glass system. The sintering behavior of the samples' physical, structural, and mechanical properties is examined. The results showed that sintering improved the crystallization and hardness of the final product. The bioactive glass-ceramics sintered at 700 degrees C exhibited the highest densification and optimal mechanical properties, making them a potential candidate for dental applications.

Summary: Cementless total hip arthroplasty relies on initial press-fit fixation of femoral stems against cortical bone for osseointegration, posing challenges in stability, especially in postmenopausal women with decreased bone mineral density. Postoperative hip BMD and walking activity are significantly associated with femoral stem rotation, with height acting as a potential confounding factor. The study highlights the need for high-resolution imaging techniques to explore reasons for stem subsidence even in women with normal hip BMD.

Summary: In postmenopausal women undergoing cementless total hip arthroplasty, initial femoral stem migration, as measured by RSA, is clinically significant. Patients with less than 2mm of initial stem subsidence showed faster recovery and better patient-reported outcome measures, while those with greater subsidence had slower recovery and less satisfactory outcomes.

Summary: In a trial involving 65 postmenopausal women, denosumab failed to reduce initial migration of a cementless femoral stem despite preventing periprosthetic bone loss. Women with normal bone mineral density had significantly less stem subsidence compared to those with osteopenia and osteoporosis. Understanding 3D implant migration events can provide valuable insights for future large-scale trials.
