To assess safety and efficacy of repeated B-cell depletion with rituximab in patients rheumatoid arthritis (RA).Thirty-seven refractory RA entered into a programme B-lymphocyte (up to 5 cycles, 89 cycles total) protocols based on the anti-CD20 monoclonal antibody, rituximab, have been observed over periods >5 yrs (n = 22) or 3-5 14).Twenty two subjects followed up for yrs. Average duration benefit per cycle was 15 months (maximum 43 months), time re-treatment 20 months. Nineteen remain...

The pathogenesis of chronic joint inflammation remains unclear, although the involvement pathogen recognition receptors has been suggested recently. In present article, we describe role two members NACHT-LRR (NLR) family, Nod1 (nucleotide-binding oligomerization domain) and Nod2 in a model acute induced by intraarticular injection Streptococcus pyogenes cell wall fragments. Here, show that deficiency resulted reduced protection against early cartilage damage. contrast, gene-deficient mice...

The status of predictive biomarkers in metastatic colorectal cancer is currently underdeveloped. Our study aimed to investigate the value six circulating exosomal miRNAs derived from plasma (miR-92a-3p, miR-143-3p, miR-146a-5p, miR-221-3p, miR-484, and miR-486-5p) for chemosensitivity, resistance patterns, survival. Thirty-one patients were selected before receiving first-line irinotecan- or oxaliplatin-based chemotherapy. Blood samples harvested at baseline 4-6 months after initiation...

Background: En bloc removal of the kidney with tumor thrombus excision in a multidisciplinary team remains standard treatment for renal cell carcinoma (RCC) extension. In order to minimize hemodynamic impact surgical blood loss, intraoperative salvage (IOCS) techniques can decrease need allogeneic and prevent transfusion related complications. Objective: this article, we evaluated safety IOCS during radical nephrectomy inferior vena cava thrombectomy under cardiopulmonary bypass or without...

Introduction: Image-guided invasive procedures on the liver require a steep learning curve to acquire necessary skills. The best and safest way achieve these skills is through hands-on courses that include simulations phantoms of different complications, without any risks for patients. There are many market made various materials; however, there few multimodal phantoms, only two cast in 3D-printed mold. Methods: We created virtual mold by segmenting CT scan.

Surgical treatment of toracoabdominal aortic aneurysms (TAAA) represents a difficult problem for the vascular surgeon and may become formidable challenge in an emergency procedure. In patient with hemodynamic instability, protective measures as cerebral spinal fluid drainage bio-pump against cord, visceral renal ischemia, be ineffective or impracticable.We report our experience 51 emergency-operated patients TAAA out 660 treated between 1994 2014; 48 (94%) were hemodynamically unstable, 3...
