Purpose of the study : The aim of this study was to evaluate the impact of 3D and 2D vision on performance of novice subjects using da Vinci robotic system. Methods : 224 nurses without any surgical experience were divided into two groups and executed a motor task with the robotic system in 2D for one group and with the robotic system in 3D for the other group. Time to perform the task was recorded. Results : Our data showed significant better time performance in 3D view (24.67 +/- 11.2) than in 2D view (40.26 +/- 17.49, P < 0.001). Conclusions : Our findings emphasized the advantage of 3D vision over 2D view in performing surgical task, encouraging the development of efficient and less expensive 3D systems in order to improve the accuracy of surgical gesture, the resident training and the operating time.

Objective: To evaluate the long-term safety and efficacy of etanercept in patients with rheumatoid arthritis. Methods: 549 patients entered this 5-year, open-label extension study and received etanercept 25 mg twice weekly. All patients showed inadequate responses to disease-modifying antirheumatic drugs before entry into the double-blind studies. Safety assessments were carried out at regular intervals. Primary efficacy end points were the numbers of painful and swollen joints; secondary variables included American College of Rheumatology (ACR) response rate, Disease Activity Score and acute-phase reactants. Efficacy was analysed using the last-observation-carried-forward approach. Results: Of the 549 patients enrolled in the open-label trial, 467 (85%), 414 (75%) and 371 (68%) completed 1, 2 and 3 years, respectively; 363 (66%) remained in the study at the time of this analysis. A total exposure of 1498 patient-years, including the double-blind study, was accrued. In the open-label trial, withdrawals for efficacy-related and safety-related reasons were 11% and 13%, respectively. Frequent adverse events included upper respiratory infections, flu syndrome, rash and injection-site reactions. Rates of serious infections and malignancies remained unchanged over the course of the study; there were no reports of patients with central demyelinating disease or serious blood dyscrasias. After 3 years, ACR20, ACR50 and ACR70 response rates were 78%, 51% and 27%, respectively. The Disease Activity Score score was reduced to 3.0 at 3 months and 2.6 at 3 years from 5.1. A sustained improvement was found in Health Assessment Questionnaire scores throughout the 3-year time period. Conclusion: After 3 years of treatment, etanercept showed sustained efficacy and a favourable safety profile. [less ▲]

We propose a multi-dimensional strategy, associating immunodetection to a protein fractionating two-dimensional liquid chromatography tool, for serological characterization of microbial antigens. The originality of such immunoproteomic approaches resides in their application in large-scale studies for rapid serotyping of micro-organisms, evaluation of immunomes and could be proposed in the development and monitoring of vaccines.

Since the beginning of RHD genotyping in maternal plasma, no Rh D positive baby was diagnosed RHD negative in our institution. Genotyping from circulating DNA in maternal plasma is as efficient as genotyping on amniocyts but without the associated risks. We propose a prophylactic injection based on fetal genotyping RHD in maternal blood with 300 microg anti-D immunoglobulin at 28 weeks of amenhorrea in all of Rh D negative pregnant women whitch fetuses positive RHD.

In this paper we consider the question of parameter identifiability for biochemical reaction networks, as typically encountered in systems biology. Specifically, we are interested in deriving conditions on the biochemical reaction network and on the measured outputs that guarantee identifiability of the parameters. Taking the specific system structure of biochemical reaction networks into account, we derive sufficient conditions for local parameter identifiability based on a suitable system expansion which does not any more directly depend on the parameters. Rather, as shown, the problem of identifiability can be recast as the question of observability of the (parameter free) expanded system. The conditions derived are exemplified considering a simple example [less ▲]

Aim of the study : To evaluate the role of perioperative, catheter-guided fibrinolysis in the management of thrombosed popliteal artery aneurysms. Material : From 1990 to 2005, six patients suffering subacute limb ischemia, secondary to thrombosis of a popliteal artery aneurysm, benefited selective intra-arterial fibrinolysis, followed by subsequent aneurysm exclusion and bypass grafting. This represents ten percent of all popliteal aneurysms operated on in that time period and 28% of all thrombosed popliteal artery aneurysms. Results : The lytic procedure was successful in all cases, restituting patency in two (n = 3), one (n = 2) or all (n = 1) crural arteries. The venous bypass graft remained patent in all but one patient. In one patient, the graft occluded at 10 months without limb loss. This outcome compares more favorable than the result obtained with emergent surgery alone for thrombosed popliteal artery aneurysms with profound limb ischemia (eight patients, of whom one required amputation at day 5 and one lost his limb at nine months following graft thrombosis). Conclusion : Preoperative intra-arterial lytic therapy, in the setting of subacute limb ischemia caused by thrombosis of a popliteal artery aneurysm, can be considered as safe and effective.

We isolated 59 strains of cyanobacteria from the benthic microbial mats of 23 Antarctic lakes, from five locations in two regions, in order to characterize their morphological and genotypic diversity. On the basis of their morphology, the cyanobacteria were assigned to 12 species that included four Antarctic endemic taxa. Sequences of the ribosomal RNA gene were determined for 56 strains. In general, the strains closely related at the 16S rRNA gene level belonged to the same morphospecies. Nevertheless, divergences were observed concerning the diversity in terms of species richness, novelty, and geographical distribution. For the 56 strains, 21 operational taxonomic units (OTUs, defined as groups of partial 16S rRNA gene sequences with more than 97.5% similarity) were found, including nine novel and three exclusively Antarctic OTUs. Sequences of Petalonema cf. involvens and Chondrocystis sp. were determined for the first time. The internally transcribed spacer (ITS) between the 16S and the 23S rRNA genes was sequenced for 33 strains, and similar groupings were observed with the 16S rRNA gene and the ITS, even when the strains were derived from different lakes and regions. In addition, 48 strains were screened for antimicrobial and cytotoxic activities, and 17 strains were bioactive against the gram-positive Staphylococcus aureus, or the fungi Aspergillus fumigatus and Cryptococcus neoformans. The bioactivities were not in coincidence with the phylogenetic relationships, but rather were specific to certain strains. [less ▲]

The authors discuss the potential influence of obesity surgery on the risk of cancer, focusing on the upper GI tract directly affected by operations. There is currently no substantiation for an increased risk of cancer after bariatric surgery, because there are only about 25 reports of subsequent cancer of the esophagus and the stomach. However, this review emphasizes the need to detect potential precancerous conditions before surgery. Candidates for postoperative endoscopic surveillance may include patients >15 years after gastric surgery, but also patients symptomatic for gastroesophageal reflux disease in whom a high incidence of Barrett's metaplasia has been reported. The greatest concern is a delay in diagnosis from inadequate investigation due to mistaking serious upper GI symptoms as a consequence of the past operation. [less ▲]

Context. Since the discovery, with the EINSTEIN satellite, of strong X-ray emission associated with HD 93162 (equivalent to WR 25), this object has been predicted to be a colliding-wind binary system. However, radial-velocity variations that would prove the suspected binary nature have yet to be found. Aims. We spectroscopically monitored this object to investigate its possible variability to address this discordance. Methods. We compiled the largest available radial-velocity data set for this star to look for variations that might be due to binary motion. We derived radial velocities from spectroscopic data acquired mainly between 1994 and 2006, and searched these radial velocities for periodicities using different numerical methods. Results. For the first time, periodic radial-velocity variations are detected. Our analysis definitively shows that the Wolf-Rayet star WR 25 is an eccentric binary system with a probable period of about 208 days. [less ▲]
