Objective: To examine whether Lapprotector, a protective film and ring device for protecting wounds, can prevent wound infection after open appendectomy.
Methods: We performed open appendectomy on 64 patients between 2004 and 2006. In September 2005, we started using Lapprotector to protect the site of incision (McBurney's point). Patients were divided into two groups as follows: Lapp(-), n = 32; Lapp(+), n = 32. Patient demographics were not statistically different and antibiotic protocols were identical.
Results: In the Lapp(-) group, the appendix was perforated in seven patients (21.9%) and not perforated in 25 patients (78.1%). In the Lapp(+) group, the appendix was perforated in nine patients (28.1%) and not perforated in 23 patients (71.9%). For perforated cases, incisional wound infection was seen in three out of seven patients (42.9%) in the Lapp(-) group and in no patient (0%) in the Lapp(+) group, a significant difference (p < 0.05, Chi-squared test). For nonperforated cases, wound infection was seen in only one out of 25 patients (4.0%) in the Lapp(-) group.
Conclusion: We recommend using Lapprotector to prevent incisional wound infection in patients requiring open appendectomy, especially in cases where the appendix is perforated.

Purpose: Tibial open shaft fractures are very common and susceptible to infection, which can lead to significant morbidity especially infection and non-union. Antibiotic coated nail is one option for fixing open shaft tibial fractures to minimise infection. This study aimed to compare the clinical outcome of Gentamicin-coated tibial nails versus regular unreamed interlocking tibial nails in the treatment of type I and II tibial open fractures.

Dissecting the spatial heterogeneity of cancer-associated fibroblasts (CAFs) is vital for understanding tumor biology and therapeutic design. By combining pathological image analysis with spatial proteomics, we revealed two stromal archetypes in hepatocellular carcinoma (HCC) with different biological functions and extracellular matrix compositions. Using paired single-cell RNA and epigenomic sequencing with Stereo-seq, we revealed two fibroblast subsets CAF-FAP and CAF-C7, whose spatial enrichment strongly correlated with the two stromal archetypes and opposing patient prognosis.

This study reports the development of a highly absorbent Chitosan (CS)/Tannic Acid (TA) sponge, synthesized via chemical cross-linking with Epichlorohydrin (ECH) and integrated with zinc oxide nanoparticles (ZnO NPs) as a novel hemostatic anti-infection agent. The chemical properties of the sponges were characterized using Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and zeta potential measurements. Morphological and elemental analyses conducted through scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDAX) revealed a uniform distribution of ZnO NPs, with particle sizes below 20 nm.

The healing of bacteria-infected wounds has long posed a significant clinical challenge. Traditional hydrogel wound dressings often lack self-healing properties and effective antibacterial characteristics, making wound healing difficult. In this study, a bioactive small molecule cross-linking agent 4-FPBA/Lys/4-FPBA (FLF) composed of 4-formylphenylboronic acid (4-FPBA) and lysine (Lys) was utilized to cross-link guar gum (GG) and a tannic acid/iron (TA/Fe) chelate through multiple dynamic bonds, leading to the formation of a novel self-healing hydrogel dressing GG-FLF/TA/Fe.
