Is fluoroscopy‐guided percutaneous bone biopsy of diabetic foot with suspected osteomyelitis worthwhile? A retrospective study 一项回顾性研究:怀疑骨髓炎的糖尿病足在透视引导下经皮骨活检是否具有价值?

Journal of Diabetes, Volume 15, Issue 4, Page 332-337, April 2023., 2023
Abstract Background Diabetic foot infection, particularly osteomyelitis, is a major risk factor of amputation in persons with diabetes. Bone biopsy with microbial examination is considered the gold standard of diagnosis of osteomyelitis, providing information about the offending pathogens as well as their antibiotics susceptibility.

Influence of hospital size on antimicrobial resistance and advantages of restricting antimicrobial use based on cumulative antibiograms in dogs with Staphylococcus pseudintermedius infections in Japan

Veterinary Dermatology, Volume 32, Issue 6, Page 668-e178, December 2021., 2021
Background Antimicrobial resistance in Staphylococcus pseudintermedius (SP) and the prevalence of meticillin‐resistant SP (MRSP) is increasing in dogs worldwide. Objectives To evaluate the influence of hospital size on antimicrobial resistance of SP and whether restricted use of antimicrobials based on antibiograms could reduce the identification of ...

Chemical and microbiological stability of diluted ceftazidime in three different solutions under three storage temperatures over a 28 day period

Veterinary Dermatology, Volume 32, Issue 5, Page 456-e124, October 2021., 2021
Background – Ceftazidime (CAZ) solutions are being used based on anecdotal reports for otitis externa complicated by multidrug‐resistant Pseudomonas aeruginosa (MDR PA). The chemical and microbiological stability of these proposed compounded solutions have not been evaluated, and likely are affected by the diluent and storage duration or temperature ...

Clindamycin resistance of skin derived Staphylococcus pseudintermedius is higher in dogs with a history of antimicrobial therapy

Veterinary Dermatology, Volume 31, Issue 4, Page 305-e75, August 2020., 2020
Background – In the Netherlands there is a lack of data regarding resistance of Staphylococcus pseudintermedius to the systemic antimicrobial drugs used for the treatment of superficial pyoderma. Objectives – To assess antimicrobial resistance, with emphasis on resistance to clindamycin and meticillin, in clinical isolates of S.

Faecalibacterium prausnitzii‐derived microbial anti‐inflammatory molecule regulates intestinal integrity in diabetes mellitus mice via modulating tight junction protein expression 普拉梭菌活性产物‐微生物抗炎分子通过调控细胞紧密连接蛋白表达修复糖尿病小鼠肠道屏障

Journal of Diabetes, Volume 12, Issue 3, Page 224-236, March 2020., 2020
Highlights Diabetic conditions induce compositional dysbiosis of the gut microbiota and impair gut barrier integrity. Diabetic conditions markedly downregulate the abundance of Faecalibacterium prausnitzii in the gut. Under diabetic conditions, microbial anti‐inflammatory molecules from Faecalibacterium prausnitzii restore the gut barrier and ZO‐1 ...

A Carboxymethyl Chitosan/Tannic Acid@Ag Composite Hydrogel for Gastrointestinal Defect Sealing and Smart Motion Monitoring

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Conductive hydrogels show great potential in flexible electronics and biomedical devices, yet their practical applications are often hindered by insufficient mechanical strength, poor environmental stability, and limited functionality. To address these challenges, this study has developed a hydrogel platform that integrates diagnosis and ...

Synergistic Effect of Hydrophilic Surface and Nano‐Ag2O in TiO2‐Based Composites Coating on Antibacterial and Osteogenic Properties of Low Modulus Ti‐Mo‐Ag Alloy

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Ti‐15Mo‐2.5Ag alloy exhibited a low modulus and strong antibacterial ability but poor bioactivity. To resolve this problem, sandblasting and anodization were used to create a hydrophilic and nano‐Ag2O‐containing TiO2 coating. Subsequently, the microstructure and physicochemical properties were investigated by scanning electron microscopy, X ...

Preparation of Highly Bioactive Nanolignin via Dopamine Mannich Modification and Its Synergistic Effects With Zn2+ in PVA Hydrogels

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Lignin is a natural non‐toxic polyphenolic macromolecule, which shows inherent antioxidant and broad‐spectrum antibacterial activities. However, due to the low content and the high bond dissociation energy of phenolic hydroxyl groups (Ar‐O·H), its antioxidant and antibacterial activities are relatively weak, which limits its application as a ...

3D Printed High‐Strength Hydrogel for Dual Release of Cu2+ and Ag+ Ions to Enhance Bone Repair and Antibacterial Properties

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.
