AI Article Synopsis
- - Foot and ankle surgeons are researching bone graft alternatives to autologous bone and this study focuses on using bioactive glass for hindfoot arthrodesis in patients at risk for delayed healing.
- - A retrospective review was conducted on 29 patients who underwent surgeries on 48 joints, all possessing at least one risk factor for nonunion, and were followed for over 24 weeks.
- - The results showed a 25% nonunion rate overall and indicated that the union rates with bioactive glass were comparable to those achieved with autografts and other bone graft substitutes.
Article Abstract
Foot and ankle surgeons continue to explore bone graft alternatives that will be comparable to the reference standard of autologous bone. The purpose of the present study was to consider the outcomes of hindfoot arthrodesis supplemented with bioactive glass in patients at risk of delayed union and nonunion. We performed a retrospective radiographic review of 29 consecutive patients (48 joints) who had undergone arthrodesis of ≥1 joint of the hindfoot (ankle, subtalar, talonavicular, calcaneocuboid). All patients included in the present study had a minimum of 1 documented risk factor for osseous nonunion (history of previous nonunion, trauma, smoking, diabetes, Charcot arthropathy, obesity, age >65 years at surgery). The patients were followed up for a minimum of 24 weeks or until radiographic healing had been achieved. We found 12 (25.0%) nonunions across all 48 joints supplemented with bioactive glass. We found 4 (16.7%) nonunions in the subtalar joint, 1 (11.1%) in the calcaneocuboid joint, and 1 (11.1%) in the talonavicular joint. We found that hindfoot arthrodesis procedures supplemented with bioactive glass resulted in an incidence of union comparable to that with autograft and other bone graft substitutes.

Introduction: () infection is highly prevalent globally and poses a significant public health challenge due to its link with chronic gastritis, peptic ulcers, and gastric malignancies. 's persistence within the gastric environment, particularly in case of infection with virulent strains, triggers chronic inflammatory responses and mucosal damage. Antibiotic therapy is the primary approach for eradication, but antibiotic resistance and adverse effects hinder treatment efficacy.

The mechanisms underlying the impact of probiotic supplementation on health remain largely elusive. While previous studies primarily focus on the discovery of novel bioactive bacteria and alterations in the microbiome environment to explain potential probiotic effects, our research delves into the role of living Lactiplantibacillus (formerly known as Lactobacillus) and their conditioned media, highlighting that only the former, not dead bacteria, enhance the healthspan of Caenorhabditis elegans (C. elegans).
