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...

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...

INTRODUCTION: Several studies have shown that aerobic exercise is effective in treating the depression and improving the mental health. There are various theories which explains why aerobic exercise is effective in the treatment of depression and improve mental health, but there are limited studies to show how cognitive components and depression improve during aerobic exercises. AIM: The current study was carried out to investigate the cognitive change process during aerobic exercises in depressed students...

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...

Halloysite is a natural nanotubular clay mineral (HNTs, Halloysite Nano Tubes) chemically identical to kaolinite and, due to its good biocompatibility, is an attractive nanomaterial for a vast range of biological applications. Chitosan oligosaccharides are homo- or heterooligomers of N-acetylglucosamine and D-glucosamine, that accelerate wound healing by enhancing the functions of inflammatory and repairing cells. The aim of the work was the development of a nanocomposite based on HNTs and chitosan oligosaccharides, to be used as pour powder to enhance healing in the treatment of chronic wounds...

Susanna Hewon Shin, Benjamin Ware Starnes
BACKGROUND: Up to 40% of abdominal aortic aneurysms (AAAs) have coexistent iliac artery aneurysms (IAAs). In the past, successful endovascular repair required internal iliac artery (IIA) embolization, which can lead to pelvic or buttock ischemia. This study describes a technique that uses a readily available solution with a minimally altered off-the-shelf bifurcated graft in the IAA to maintain IIA perfusion. METHODS: From August 2009 to May 2015, 14 patients with AAAs and coexisting IAAs underwent repair with a bifurcated-bifurcated approach...

BACKGROUND: Despite a multitude of evidence-based prediction models and risk factors for postoperative complications after ventral hernia repair, estimating a patient's risk of postoperative complications after ventral hernia repair remains challenging. In an attempt to improve the preoperative assessment of complex hernia patients, some studies have examined pulmonary changes after hernia repair hypothesizing that large hernias lead to pulmonary changes and increased pulmonary complication rates...

An open posterior component separation (PCS) is a commonly utilized surgical approach for repair of complex abdominal wall defects and hernias. Although this approach may improve surgical outcomes, significant postoperative pain can be expected given the required laparotomy and extensive abdominal wall manipulation. Both systemic opioids and thoracic epidural analgesia (TEA) are viable postoperative analgesic options, and both are commonly utilized. Although the benefits of TEA have been investigated following a variety of surgeries, there is a paucity of literature related to its efficacy for this particular surgery...

A moisturizing cream mixed with a steroid ointment is frequently prescribed to patients suffering from atopic dermatitis. However, there is a concern that the mixing operation causes destabilization. The present study was performed to investigate the stability of such preparations closely using magnetic resonance imaging (MRI). As sample preparations, five commercial moisturizing creams that are popular in Japan were mixed with an ointment base, a white petrolatum, at a volume ratio of 1 : 1. The mixed preparations were stored at 60°C to accelerate the destabilization processes...
