This video provides a step-by-step guide for performing the hybrid endoscopic thoracic discectomy using navigation and robotic arm for addressing high migrated calcified disc herniation. With the development of techniques, endoscopic spine surgery has emerged as a reliable treatment for thoracic myelopathy. This approach offers high-resolution, off-axis visualization of the surgical field.

This study investigates the green synthesis of chitosan-based silver nanoparticles (Ag NPs) and their application as antimicrobial coatings for food preservation. The effects of three coatings were evaluated on refrigerated tomatoes over 22 days: distilled water (control), 1 % chitosan (CH), and chitosan-based Ag NPs (Ag/CH). The synthesized Ag/CH was characterized by FT-IR, UV-vis spectroscopy, SEM, TEM, DLS, and XRD, confirming successful synthesis and a crystalline face-centered cubic structure.

Multifunctional wound dressings with antibacterial and antioxidant properties hold significant promise for treating chronic wounds; however, achieving a balance of these characteristics while maintaining biocompatibility is challenging. To enhance this balance, this study focuses on the design and development of 3D-printed chitosan-matrix composite scaffolds, which are incorporated with varying amounts of cerium oxide nanoparticles (0, 1, 3, 5, and 7 wt%) and subsequently coated with a vancomycin-loaded alginate layer. The structure, antibiotic drug delivery kinetics, biodegradation, swelling, biocompatibility, antibacterial, antioxidant, and cell migration behaviors of the fabricated dressings were evaluated in-vitro.

Article Synopsis
- The study examined antibiotic resistance in carbapenem-resistant Klebsiella pneumoniae (CRKP) isolates in Europe, focusing on changes influenced by aging populations, migrations, and climate change over the last three years.
- Researchers compared hospital and community isolates to analyze resistance mechanisms, trends, and types of carbapenemases and plasmids, using methods like disk diffusion and PCR.
- Results showed high resistance rates to common antibiotics, with OXA-48 being the predominant carbapenemase found in the majority of isolates, indicating a similar trend to neighboring countries.

Purpose: To describe two patients affected by optic disk pit-maculopathy ODP-M surgically treated with pars-plana vitrectomy (PPV) and the apposition of a human Amniotic Membrane (hAM) patch.
Methods: Patients underwent a PPV with the apposition of a hAM patch to cover the ODP. In case 1, a 2 surgery was necessary to push the hAM patch inside the pit, whereas in case 2 the patch was pulled inside the pit following the pressure gradient when infusion was turned on.
