Background: Primary closure of large ventral hernia is difficult and is usually complicated by postoperative mesh bulge, migration, and higher recurrence. Techniques like component separation and bridging mesh, transversus abdominus release, da Silva triple-layer repair, and peritoneal flap hernioplasty (PFH) are common treatment options.
Objective: To evaluate the early postoperative and long-term outcomes of PFH for large ventral hernias.
Methods: A systematic literature search was performed on the electronic databases of PubMed, Web of Knowledge, and Scopus till July 28, 2024. We performed a single-arm meta-analysis of non-comparative studies using OpenMeta[Analyst] software (Center for Evidence-Based Medicine, Brown University, Rhode Island, USA).
Results: Five studies including 432 patients (238 male and 194 female patients in a ratio of 1.23:1.0) underwent PFH for large ventral hernia. The estimated proportion of patients who may experience skin necrosis, seroma, hematoma, superficial surgical site infection, and deep mesh infection were 1.2% (95% CI: 0.001, 0.022; I: 0.53%) 5.8% (95% CI: 0.036, 0.080; I: 0%), 3.7% (95% CI: 0.007, 0.067; I: 59.32%), 10.6% (95% CI: 0.077, 0.135; I: 0%), and 0.9% (95% CI: -0.004, 0.022; I: 15.99%) respectively. Similarly, the estimated recurrence rate and chronic pain following PFH was 1.9% (95% CI: 0.005, 0.033; I: 2%) and 11.6% (95% CI: 0.032, 0.200; I: 83.43%) respectively during the mean follow-up time of 33 months (95% CI: 1.9, 64.1).
Conclusion: PFH seems to be a safe and feasible procedure for the repair of complex or large ventral hernias where it is difficult to perform primary fascial closure. Further studies with a direct comparison of PFH with component separation techniques are necessary to validate the results of our study.

Hearing is an active process in which listeners must detect and identify sounds, segregate and discriminate stimulus features, and extract their behavioral relevance. Adaptive changes in sound detection can emerge rapidly, during sudden shifts in acoustic or environmental context, or more slowly as a result of practice. Although we know that context- and learning-dependent changes in the sensitivity of auditory cortical (ACX) neurons support many aspects of perceptual plasticity, the contribution of subcortical auditory regions to this process is less understood.

Background: Systemic inflammation in patients with Alzheimer's disease (AD) has been associated with an exacerbation in cognitive decline, but the underlying mechanisms remain largely unknown. In AD, intraneuronal hyperphosphorylated tau spreads through the brain via trans-synaptic prion-like propagation. Evidence suggests that propagation of tau pathology is linked to neuroinflammation.

Background: Although it is well established that lower cognitive performance, on average, is associated with a greater risk of developing Alzheimer's disease (AD) dementia, it is unclear whether distinct cognitively-defined subgroups exist among non-demented older adults and whether such profiles map onto distinct AD neuroimaging measure profiles.
Method: The sample consisted of 167 non-demented older adults from the BIOCARD study with comprehensive neuropsychological and clinical evaluations, amyloid PET and brain MRI scans. The MRI measure included: global cortical volume in AD-signature regions and a medial-temporal lobe composite; resting-state functional connectivity within 5 large-scale cognitive networks; global white matter microstructure, index by fractional anisotropy (FA) and radial diffusion (RD) on DTI scans; and global white matter hyperintensity (WMH) volume on FLAIR scans.

Human medial parietal cortex (MPC) is recruited during multiple cognitive processes. Previously, we demonstrated regions specific to recall of people or places and proposed that the functional organization of MPC mirrors the category selectivity defining the medial-lateral axis of ventral temporal cortex (VTC). However, prior work considered recall of people and places only and VTC also shows object-selectivity sandwiched between face- and scene-selective regions.

The insular cortex (ICx) has a role in large a variety of functions. Thalamus plays an important role in modulating cortical functions. The present study aims to show thalamic-ICx connections using the fluoro-gold (FG) tracing method in rats and diffusion tensoring-based tractography (DTI) in humans.
