Abstract
Here, we present surface analysis and biocompatibility evaluation of novel composite material based on graphene oxide traded as Hastalex. First, the surface morphology and elemental analysis of the pristine material were examined by atomic force and scanning electron microscopies, and by energy-dispersive and X-ray photoelectron spectroscopies, respectively. The Hastalex surface was then modified by plasma (3 and 8 W with exposure times up to 240 s), the impact of which on the material surface wettability and morphology was further evaluated. In addition, the material aging was studied at room and elevated temperatures. Significant changes in surface roughness, morphology, and area were detected at the nanometer scale after plasma exposure. An increase in oxygen content due to the plasma exposure was observed both for 3 and 8 W. The plasma treatment had an outstanding effect on the cytocompatibility of Hastalex foil treated at both input powers of 3 and 8 W. The cell number of human MRC-5 fibroblasts on Hastalex foils exposed to plasma increased significantly compared to pristine Hastalex and even to tissue culture polystyrene. The plasma exposure also affected the fibroblasts' cell growth and shape.

Abstract
Current research in the area of surgical mesh implants is somewhat limited to traditional designs and synthesis of various mesh materials, whereas meshes with multiple functions may be an effective approach to address long-standing challenges including postoperative complications. Herein, a bioresorbable electronic surgical mesh is presented that offers high mechanical strength over extended timeframes, wireless post-operative pressure monitoring, and on-demand drug delivery for the restoration of tissue structure and function. The study of materials and mesh layouts provides a wide range of tunability of mechanical and biochemical properties. Dissolvable dielectric composite with porous structure in a pyramidal shape enhances sensitivity of a wireless capacitive pressure sensor, and resistive microheaters integrated with inductive coils provide thermo-responsive drug delivery system for an antibacterial agent. In vivo evaluations demonstrate reliable, long-lived operation, and effective treatment for abdominal hernia defects, by clear evidence of suppressed complications such as adhesion formation and infections.

Artificial Intelligence (AI) Based Analysis of In Vivo Polymers and Collagen Scaffolds Inducing Vascularization. In Vivo 2024; 38:620-629. [PMID: 38418141 PMCID: PMC10905450 DOI: 10.21873/invivo.13481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 01/03/2024] [Accepted: 01/10/2024] [Indexed: 03/01/2024]
Abstract
BACKGROUND/AIM Biomaterials are essential in modern medicine, both for patients and research. Their ability to acquire and maintain functional vascularization is currently debated. The aim of this study was to evaluate the vascularization induced by two collagen-based scaffolds (with 2D and 3D structures) and one non-collagen scaffold implanted on the chick embryo chorioallantoic membrane (CAM). MATERIALS AND METHODS Classical stereomicroscopic image vascular assessment was enhanced with the IKOSA software by using two applications: the CAM assay and the Network Formation Assay, evaluating the vessel branching potential, vascular area, as well as tube length and thickness. RESULTS Both collagen-based scaffolds induced non-inflammatory angiogenesis, but the non-collagen scaffold induced a massive inflammation followed by inflammatory-related angiogenesis. Vessels branching points/Region of Interest (Px^2) and Vessel branching points/Vessel total area (Px^2), increased exponentially until day 5 of the experiment certifying a sustained and continuous angiogenic process induced by 3D collagen scaffolds. CONCLUSION Collagen-based scaffolds may be more suitable for neovascularization compared to non-collagen scaffolds. The present study demonstrates the potential of the CAM model in combination with AI-based software for the evaluation of vascularization in biomaterials. This approach could help to reduce and replace animal experimentation in the pre-screening of biomaterials.

Ann Med Surg (Lond) 2024; 86:1072-1075. [PMID: 38333272 PMCID: PMC10849424 DOI: 10.1097/ms9.0000000000001531] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Accepted: 11/12/2023] [Indexed: 02/10/2024] Open
Abstract
Introduction Pelvic organ prolapse (POP) is a prevalent condition among parous women, often warranting surgical intervention. This case accentuates the complications associated with mesh in POP surgeries, iterating the imperative need for an evidence-based approach towards its utilization and exhaustive patient counselling. Case presentation A 60-year-old female, post-mesh-augmented POP repair, embarked on a 13-year journey characterized by persistent pelvic pain and multiple interventions. Despite undergoing several surgeries across different countries, involving mesh and stone removals, her symptoms, notably pelvic pain and dyspareunia, persisted. Clinical examinations revealed mesh erosion into the perivesical tissue, bladder, and associated stones, which were addressed through multiple interventions, albeit with transient success. Discussion The complex journey of this patient exemplifies the intricate challenges mesh poses in POP surgeries. While mesh application offers a minimally invasive approach and has proven successful in numerous cases, it simultaneously opens a Pandora's box of potential severe complications, necessitating thorough patient counselling and post-surgery management. Conclusion The case delineates the challenging path that clinicians and patients tread when navigating through mesh-associated complications post-POP repair. Although mesh has been heralded as a revolutionary approach in POP surgeries, its potential drawbacks necessitate judicious application, ensuring clinicians are well-versed with its associated risks and are adept in managing ensuing complications.

Safety and Efficacy of Vaginal Implants in Pelvic Organ Prolapse Surgery: A Meta-analysis of 161 536 Patients. Eur Urol Focus 2023:S2405-4569(23)00243-2. [PMID: 37968187 DOI: 10.1016/j.euf.2023.11.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Accepted: 11/02/2023] [Indexed: 11/17/2023]
Abstract
CONTEXT Among the many surgical treatments for pelvic organ prolapse (POP), better results can be achieved with the use of vaginal implants. However, owing to perceived complications, vaginal implant surgeries have been restricted or banned in many countries. OBJECTIVE To assess the real value of vaginal implants in POP surgery and compare the safety and efficacy of operations with and without implants. EVIDENCE ACQUISITION A systematic search was performed in three medical databases. Randomised controlled trials and observational studies comparing the safety and efficacy of vaginal POP surgery with implants versus native tissue were included. Safety outcomes were defined as different types of complications (functional and non-functional) and reoperations for complications. Efficacy outcomes were parameters of anatomical success and the rate of reoperations due to recurrence. A multivariate meta-analysis framework was used to estimate pooled odds ratios (ORs) with confidence intervals (CIs) with simultaneous control for study correlations and estimation of multiple correlated outcomes. EVIDENCE SYNTHESIS We included 50 comparative studies in the analysis. Rates of reoperation for complications (OR 2.15, 95% CI 1.20-3.87), vaginal erosion (OR 14.05, 95% CI 9.07-21.77), vaginal bleeding (OR 1.67, 95% CI 1.25-2.23), and de novo stress urinary incontinence (OR 1.44, 95% CI 1.18-1.75) were significantly higher in the implant group. Rates of anatomical success (OR 3.22, 95% CI 2.06-5.0) and reoperation for recurrence (OR 0.55, 95% CI 0.36-0.85) were superior in the implant group. CONCLUSIONS POP surgeries with vaginal implants are more effective than surgeries without implants, with acceptable complication rates. Therefore, the complete prohibition of implants for POP surgeries should be reconsidered. PATIENT SUMMARY We compared vaginal surgery with and without implants for repair of pelvic organ prolapse. Despite higher complication rates, vaginal implants provide better long-term results overall than surgery without implants.
