Background: Biologic mesh is often used in complex hernia repair, but there has been limited clinical evidence to date to support this practice. The aim of this study was to compare clinical and patient-reported outcomes of biologic versus synthetic mesh for complex open ventral hernia repair (OVHR) at 3 years.
Methods: Patients from a single center, randomized, controlled, pilot trial comparing biologic versus synthetic mesh in complex OVHR were followed for 3 years. The primary outcome focused on major complications, namely mesh infections, hernia recurrences, reoperations, and deaths. Secondary outcomes included surgical site infections, surgical site occurrences, and patient-reported outcomes. Outcomes were assessed using frequentist generalized linear models.
Results: A total of 87 patients (44 biologic mesh, 43 synthetic mesh) were randomized, and 61 patients (70%; 28 biologic and 33 synthetic) completed 3-year follow-up. Baseline demographics were similar in both groups. No significant differences were seen in major complications (50% vs 30%, = .123), mesh infection (14% vs 3%, = .144), recurrence (39% vs 24%, = .214), reoperation (14% vs 9%, = .531), or mortality (4% vs 0%, = .459) between the 2 arms. A single death occurred as a result of bacteremia in a patient with hepatocellular carcinoma. Similarly, no significant differences were seen in secondary or patient-reported outcomes. Both groups demonstrated clinically important improvements in quality of life and pain scores at 3 years.
Conclusion: This study failed to find benefits with biologic mesh as opposed to synthetic mesh in complex OVHR at 3 years when comparing both clinical and patient-reported outcomes.

Recalcitrant biofilm infections pose a great challenge to human health. Micro- and nanorobots have been used to eliminate biofilm infections in hard-to-reach regions inside the body. However, applying antibiofilm robots under physiological conditions is limited by the conflicting demands of accessibility and driving force.

Purpose: As the use of robotic platforms for inguinal hernia repairs continues to grow, the rTAPP (Robotic Trans-Abdominal Pre-Peritoneal) approach is being performed significantly more often than rTEP (Robotic Totally Extra-Peritoneal) and is predominantly taught to newly trained robotic surgeons. This study's primary objective was to evaluate the feasibility of a proposed modified rTEP technique that incorporates balloon dissection as a primary tool, enabling the horizontal placement of three trocars aligned with the umbilicus. Secondary objectives included evaluation of safety and effectiveness of this technique, and of the learning curve required to reach proficiency.

Specialized, maternally derived ribonucleoprotein (RNP) granules play an important role in specifying the primordial germ cells in many animal species. Typically, these germ granules are small (∼100 nm to a few microns in diameter) and numerous; in contrast, a single, extremely large granule called the oosome plays the role of germline determinant in the wasp The organizational basis underlying the form and function of this unusually large membraneless RNP granule remains an open question. Here we use a combination of super-resolution and transmission electron microscopy to investigate the composition and morphology of the oosome.

Background: Schizophrenia and psychotic disorders are disabling, complex and severe psychiatric conditions, which may pose a significant therapeutic challenge. Integrating current psychopharmacological treatment with psychosocial interventions demonstrated a higher efficacy in terms of prognosis. However, most schizophrenia or psychotic patients may have restricted or no access to evidence-based psychosocial interventions, mainly due to poor dissemination of specialized interventions or stigma.
