BACKGROUND: The abdominal wall may be severely compromised in the vast majority of intestinal and multiorgan transplant candidates, and sometimes as a consequence of complex liver transplantation. Multiple options have been described to overcome this problem, varying from component separation to the extreme need of performing an abdominal wall transplantation. The aim of the present paper is to report the largest and longest-term results of patients that received an abdominal rectus fascia (ARF) after liver, intestinal, or multiorgan transplantation at a single transplant center...

INTRODUCTION: Abdominal wall reconstruction using posterior component separation with transversus abdominis release (AWTAR) produces a unique post-operative CRP profile, when compared to routine elective colorectal operations. Therefore, we aim to establish the normal post-operative C-reactive protein (poCRP) profile following AWRTAR and reduce the unnecessary invasive interventions in patients already at greater risk of septic complications. METHODS: A retrospective analysis of daily poCRP levels was performed both for patients who underwent uncomplicated AWRTAR (n=12), and a comparator group of uncomplicated open right hemicolectomies (RH) matched for age and sex (n=24)...

INTRODUCTION: Little is known about the predictors of increased ambulatory costs following open ventral and incisional hernia repair (VIHR); however, postoperative complications would be expected to be associated with an increased burden on outpatient resources. The purpose of this study is to evaluate the impact of perioperative factors on outpatient resource utilization following VIHR. METHODS: With IRB approval, the surgery scheduling system was queried to identify all cases of VIHR done at our institution over 3 years...

When light falls within a neuronal visual receptive field (RF) the resulting activity is referred to as the visual response. Recent work suggests this activity is in response to both the visual stimulation and the abrupt appearance, or salience, of the presentation. Here we present a novel method for distinguishing the two, based on the timing of random and non-random presentations. We examined these contributions in frontal eye field (FEF, N = 51) and as a comparison, an early stage in the primary visual cortex (V1, N = 15) of male monkeys (Macaca mulatta)...

REVIEW
Bram Cornette, Dirk De Bacquer, Frederik Berrevoet
The component separation technique (CST) has gained popularity among general surgeons in the management of giant abdominal hernia. A systematic review of the MedLine and EMBASE databases was performed. 36 observational cohort studies were included for data-analysis and divided in 4 main groups: Open Anterior Approach (OAA), Transversus Abdominis Release (TAR), Laparoscopic Anterior Approach (LAA) and Perforator Preserving Approach (PPA). Surgical Site Occurrences (SSO) occurred in 21.4%, 23.7%, 20.3% and 16...

BACKGROUND: Massive defects of the abdominal wall are commonly repaired with the component separation technique (CST) when insufficient tissue exists to close the defect primarily. Although the utility of CST has been documented in cases of large ventral hernias in adults, its application to congenital and acquired defects in pediatric patients has been largely unreported. This study is a retrospective case series discussing the success of CST at a large pediatric hospital. METHODS: Seven patients with massive abdominal wall defects, including ventral hernia and omphalocele, repaired with CST at a pediatric hospital were identified as candidates...

BACKGROUND: Repair of large incisional hernias remains a surgical and costly challenge. Temporary paralysis of the lateral abdominal wall muscles with topical administration of botulinum toxin A (BTA) is a new therapeutic concept, which may obviate the need for component separation technique (CST) for repair of large incisional hernias. Current literature on the administration of BTA as adjunct to surgical repair of abdominal incisional hernias was investigated. METHODS: The electronic databases PubMed and Embase were searched for eligible studies...

BACKGROUND: Mesh options for reinforcement of ventral/incisional hernia (VIH) repair include synthetic or biologic materials. While each material has known advantages and disadvantages, little is understood about outcomes when these materials are used in combination. This multicenter study reports on the first human use of a novel synthetic/biologic hybrid mesh (Zenapro(®) Hybrid Hernia Repair Device) for VIH repair. METHODS: This prospective, multicenter post-market clinical trial enrolled consecutive adults who underwent elective VIH repair with hybrid mesh placed in the intraperitoneal or retromuscular/preperitoneal position...

Manganese (Mn) is a toxic heavy metal exposing workers in various occupational settings and causing, among others, nervous system damage. Metal fumes of welding, a typical source of Mn exposure, contain a complex mixture of metal oxides partly in nanoparticle form. As toxic effects of complex substances cannot be sufficiently understood by examining its components separately, general toxicity and functional neurotoxicity of a main pathogenic welding fume metal, Mn, was examined alone and combined with iron (Fe) and chromium (Cr), also frequently found in fumes...

BACKGROUND: In large incisional hernias and after laparostoma midline closure may be impossible. A novel abdominal wall expander system (AWEX) is proposed and evaluated. METHODS: In patients with large incisional hernias and laparostoma where primary midline closure was impossible, AWEX was used. Patients undergoing abdominal wall reconstruction using AWEX between May 2012 and December 2015 were included. Intraoperative the abdominal wall was stretched by attaching the midline fascia borders to a retraction system under tension for 30 minutes...

Brain electrical activity recordings by electroencephalography (EEG) are often contaminated with signal artifacts. Procedures for automated removal of EEG artifacts are frequently sought for clinical diagnostics and brain computer interface (BCI) applications. In recent years, a combination of independent component analysis (ICA) and discrete wavelet transform (DWT) has been introduced as standard technique for EEG artifact removal. However, in performing the wavelet-ICA procedure, visual inspection or arbitrary thresholding may be required for identifying artifactual components in the EEG signal...

BACKGROUND: In case of complex ventral hernias, Rives-Stoppa and component separation technique are considered as favourable treatment techniques. However, mesh-related complications like recurrence, infection and chronic pain are still a common problem after mesh repair. Previous studies have reported promising results of the use of a self-gripping mesh (ProGrip™) in incisional hernia repair. This study aimed to evaluate the long term results of this mesh for complex ventral hernia treatment...

Yi-Xin Guo, Zhi-Biao Shao, Hui-Bin Tao, Kai-Liang Xu, Ting Li
Inductive proximity sensors (IPSs) present a unique no-contact advantage. They are widely preferred for displacement measurement in various industrial fields (e.g., aviation and aerospace), and they are improved continuously. When the inductance and resistance components of the IPS sensing core are separated, the influence of temperature drift on measurement can be eliminated. The complexity of online computation of component separation can be reduced using a two-dimensional look-up table method. However, this method exhibits disadvantages, such as large capacity of the look-up table, dependency on precision measurement of sensing core parameter, and nonlinear distribution of measurement resolution...

Distortion-product otoacoustic emissions (DPOAEs) arise in the cochlea in response to two tones with frequencies f1 and f2 and mainly consist of two components, a nonlinear-distortion and a coherent-reflection component. Wave interference between these components limits the accuracy of DPOAEs when evaluating the function of the cochlea with conventional continuous stimulus tones. Here, DPOAE components are separated in the time domain from DPOAE signals elicited with short stimulus pulses. The extracted nonlinear-distortion components are used to derive estimated distortion-product thresholds (EDPTs) from semi-logarithmic input-output (I/O) functions for 20 normal-hearing and 21 hearing-impaired subjects...

A neuron is categorized as "multisensory" if there is a statistically significant difference between the response evoked, e.g., by a crossmodal stimulus combination and that evoked by the most effective of its components separately. Being responsive to multiple sensory modalities does not guarantee that a neuron has actually engaged in integrating its multiple sensory inputs: it could simply respond to the stimulus component eliciting the strongest response in a given trial. Crossmodal enhancement is commonly expressed as a proportion of the strongest mean unisensory response...

Brad Denney, Jorge I de la Torre
Component separation with mesh reinforcement has become the primary modality for complex abdominal wall reconstruction. However, many fundamental questions remain unanswered, such as whether underlay versus overlay mesh placement is superior, and what is the best means of suture fixation technique for mesh placement? This study presents the senior author's technique for onlay biologic mesh placement with multipoint suture fixation in combination with component separation and its subsequent low recurrence rates...
