Long-term follow-up of open and laparoscopic repair of large incisional hernias

Long-term results after laparoscopic repair of large incisional hernias remain to be determined. The aim of this prospective study was to compare early and late complications between laparoscopic repair and open repair in patients with large incisional hernias.

Mesh shrinkage and pain in laparoscopic ventral hernia repair: a randomized clinical trial comparing suture versus tack mesh fixation

Mesh fixation during laparoscopic ventral hernia repair can be performed using transfascial sutures or metal tacks. The aim of the present study is to compare mesh shrinkage and pain between two different techniques of mesh fixation in a prospective randomized trial.

Statin therapy and the expression of genes that regulate calcium homeostasis and membrane repair in skeletal muscle

In skeletal muscle of patients with clinically diagnosed statin-associated myopathy, discrete signs of structural damage predominantly localize to the T-tubular region and are suggestive of a calcium leak. The impact of statins on skeletal muscle of non-myopathic patients is not known. We analyzed the expression of selected genes implicated in the molecular regulation of calcium and membrane repair, in lipid homeostasis, myocyte remodeling and mitochondrial function. Microscopic and gene expression analyses were performed using validated TaqMan custom arrays on skeletal muscle biopsies of 72 age-matched subjects who were receiving statin therapy (n = 38), who had discontinued therapy due to statin-associated myopathy (n = 14), and who had never undergone statin treatment (n = 20). In skeletal muscle, obtained from statin-treated, non-myopathic patients, statins caused extensive changes in the expression of genes of the calcium regulatory and the membrane repair machinery, whereas the expression of genes responsible for mitochondrial function or myocyte remodeling was unaffected. Discontinuation of treatment due to myopathic symptoms led to a normalization of gene expression levels, the genes encoding the ryanodine receptor 3, calpain 3, and dystrophin being the most notable exceptions. Hence, even in clinically asymptomatic (non-myopathic) patients, statin therapy leads to an upregulation in the expression of genes that are concerned with skeletal muscle regulation and membrane repair.

Cell-based therapy for myocardial repair in patients with acute myocardial infarction: rationale and study design of the SWiss multicenter Intracoronary Stem cells Study in Acute Myocardial Infarction (SWISS-AMI)

Recent studies report that intracoronary administration of autologous bone marrow mononucleated cells (BM-MNCs) may improve remodeling of the left ventricle after acute myocardial infarction (AMI). Subgroup analysis suggest that early treatment between days 4 and 7 after AMI is probably most effective; however, the optimal time point of intracoronary cell administration has never been addressed in clinical trials. Furthermore, reliable clinical predictors are lacking for identifying patients who are thought to have most benefit from cellular therapy.

Is the surgical repair of unruptured atherosclerotic aneurysms at a higher risk of intraoperative ischemia?

The incidence of ischemia might be increased in the surgical repair of atherosclerotic unruptured aneurysms compared to non-atherosclerotic aneurysms. The atherosclerotic wall might increase the occurrence of thrombembolic events or its rigidity might endanger the occlusion of perforators within the aneurysm vicinity.

Quality of life after acute type B dissection in the era of thoracic endovascular aortic repair

Conservative management of acute type B aortic dissection is currently being challenged by primary thoracic endovascular aortic repair. Aim was to assess outcome and quality of life after these different approaches using an adjusted standard population as benchmark.

Plicated patch repair for acquired Gerbode defect involving the tricuspid valve

Gerbode's defect, a left ventricular-to-right atrial communication, with involvement of the tricuspid valve acquired after bacterial endocarditis can be challenging to repair. We report a modified technique for a shunt closure and reconstruction of the tricuspid valve using a plicated bovine pericardial patch. Combining such a repair with a left ventricular patch resulted in a complete defect closure and competent tricuspid valve without regurgitation.

Value and pitfalls of neurophysiological monitoring in thoracic and thoracoabdominal aortic replacement and endovascular repair

The aim of our study was to analyze the neurophysiological monitoring method with regard to its potential problems during thoracic and thoracoabdominal aortic open or endovascular repair. Furthermore, preventive strategies to the main pitfalls with this method were developed.

Risk factors of mortality in different age groups after thoracic endovascular aortic repair

The aim of this study was to determine risk factors for mortality in different age groups after thoracic endovascular aortic repair (TEVAR).
