To analyze the overall performance of flexible nitinol stents used to line chimney grafts (CGs) during chimney endovascular aneurysm repair (chEVAR) of pararenal pathologies.

A retrospective review was conducted of all 116 elective patients (mean age 74.3±7.2 years; 103 men) who underwent chEVAR with balloon-expandable Advanta V12/iCAST CGs in combination with the Endurant stent-graft between January 2009 and December 2017 at a single center. CG lining with a nitinol stent was electively performed in 43 target vessels of 32 patients. The Kaplan-Meier method was used to estimate the primary outcomes of CG patency and freedom from reintervention (FFR) at the patient level and according to the use of a stent to line the CG. Estimates are reported with the 95% confidence interval (CI). Adjusted odds ratios (ORs) were calculated to identify any confounding effect between the presence/absence of a stent lining or according to the number of CGs.

The mean radiological follow-up was 27.3 months (range 22.1-32.6)el.
To present a new outcomes-based registry to collect data on outpatient endovascular interventions, a relatively new site of service without adequate historical data to assess best clinical practices. Quality data collection with subsequent outcomes analysis, benchmarking, and direct feedback is necessary to achieve optimal care.

The Outpatient Endovascular and Interventional Society (OEIS) established the OEIS National Registry in 2017 to collect data on safety, efficacy, and quality of care for outpatient endovascular interventions. Since then, it has grown to include a peripheral artery disease (PAD) module with plans to expand to include cardiac, venous, dialysis access, and other procedures in future modules. As a Qualified Clinical Data Registry approved by the Centers for Medicare and Medicaid Services, this application also supports new quality measure development under the Quality Payment Program. All physicians operating in an office-based laboratory or ambulatory surgery center can use the Regis interventional procedures (87.6%). The hospital transfer rate was 0.62%, with 88 urgent/emergent transfers and 24 elective transfers. The overall complication rate for the Registry was 1.87% (n=338), and the rate of major adverse events was 0.51% (n=92). Thirty-day mortality was 0.03% (n=6).

This report describes the current structure, methodology, and preliminary results of OEIS National Registry, an outcomes-based registry designed to collect quality performance data with subsequent outcome analysis, benchmarking, and direct feedback to aid clinicians in providing optimal care.

To investigate the effect of intravascular ultrasound (IVUS) imaging use on clinical outcomes after aortoiliac stenting in patients with peripheral artery disease (PAD).

Subjects for this retrospective analysis were derived from the OMOTENASHI registry database, which contained 803 symptomatic PAD patients (Rutherford categories 2-4) who were treated with self-expanding stent implantation for aortoiliac atherosclerotic lesions at 61 centers in Japan between January 2014 and April 2016. Of the 803 patients, 545 (67.9%) patients (mean age 73±9 years; 453 men) underwent IVUS-supported stent implantation and were compared with the 258 patients (mean age 73±8 years; 217 men) treated without IVUS. A propensity score analysis of 138 matched pairs was conducted to compare treatment strategies and clinical outcomes between patients having IVUS-supported endovascular therapy and those treated without IVUS.

Endovascular strategies and postoperative medications were not significantly different between the IVUS and no-IVUS groups. A procedure time under 1 hour was less frequent in the IVUS group, which had a longer fluoroscopy time. The 12-month restenosis rate was not significantly different between the 2 groups [10.2% (95% CI 6.9 to 14.9%) vs 10.3% (95% CI 5.4 to 18.6%), p=0.99]. There was no interaction between baseline characteristics and the association of IVUS use with restenosis risk.

Propensity score matching analysis revealed that duration and fluoroscopy time during IVUS-supported procedures were significantly longer than in cases without IVUS use, whereas the 12-month restenosis rate was not significantly different between the groups. IVUS use in aortoiliac lesions may be unnecessary.

Different cardiovascular societies worldwide have recommended the endovascular approach as the standard of care in their currently available guidelines. While endovascular treatment has established its role in daily clinical practice, a new debate has arisen regarding the indications, appropriateness, limitations, and role of open surgery. To inform this debate, the MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials databases were searched from 2010 to May 2020; the systematic search identified 5 articles published between 2011 and 2020 by 4 cardiovascular societies and the National Institute of Health and Care Excellence (NICE). Four debatable domains were assessed and analyzed diagnostic methods and screening, preoperative management, indications and treatment modalities, and postoperative follow-up and endoleak management. The review addresses controversial proposals as well as widely accepted recommendations and "gray zone" issues that need to be further investigated and analyzed, such as screening in women, medical management, and follow-up imaging. Blasticidin S nmr While the recommendations for AAA management have significant overlap and agreement among international cardiovascular societies, the NICE guidelines diverge regarding the role of open repair in aortic disease, recommending conventional surgery in most elective cases.
To present a novel angiographic scoring system that stratifies the risk of restenosis after endovascular therapy (EVT) to inform the decision to use paclitaxel-eluting devices in the femoropopliteal segment.

A prospective, multicenter registry including 1799 limbs of 1578 patients (mean age 74±9 years; 1090 men) with symptomatic peripheral artery disease undergoing intravascular ultrasound-supported femoropopliteal EVT was used as the basis for developing the angiographic score. Multivariable analysis identified baseline patient and limb characteristics associated with restenosis at 12 months. These risk factors for 12-month restenosis were explored using a generalized linear mixed model with a logit-link function in which the inter-institutional and inter-subject variability were treated as random effects. The multiple imputation method was adopted to address missing data. Results of the regression analysis are presented as the odds ratio (OR) with 95% confidence interval (CI).

Twelve-month primary pat study demonstrated a novel angiographic score for 12-month restenosis after femoropopliteal EVT in a real-world clinical practice. The developed score was significantly and independently associated with the 12-month restenosis risk, but the TASC class was not.

The genomic landscape of pediatric AML has been recently mapped and redefined thanks to large-scale sequencing efforts. Today, understanding how to incorporate the growing list of genetic lesions into a risk stratification algorithm for pediatric AML is increasingly challenging given the uncertainty regarding the prognostic impact of rare lesions. Here we review some uncommon cytogenetic lesions to be considered for inclusion in the high-risk groups of the next pediatric AML treatment protocols. We describe their main clinical characteristics, biological background and outcome. We also provide some suggestions for the management of these rare but challenging patients and some novel targeted therapeutic options.Manual assembly in the future Industry 4.0 workplace will put high demands on operators' cognitive processing. The development of mental workload (MWL) measures therefore looms large. Physiological gauges such as electroencephalography (EEG) show promising possibilities, but still lack sufficient reliability when applied in the field. This study presents an alternative measure with a substantial ecological validity. First, we developed a behavioural video coding scheme identifying 11 assembly behaviours potentially revealing MWL being too high. Subsequently, we explored its validity by analysing videos of 24 participants performing a high and a low complexity assembly. Results showed that five of the behaviours identified, such as freezing and the amount of part rotations, significantly differed in occurrence and/or duration between the two conditions. The study hereby proposes a novel and naturalistic method that could help practitioners to map and redesign critical assembly phases, and researchers to enrich validation of MWL-measures through measurement triangulation. Practitioner summary Current physiological mental workload (MWL) measures still lack sufficient reliability when applied in the field. Therefore, we identified several observable assembly behaviours that could reveal MWL being too high. The results propose a method to map MWL by observing specific assembly behaviours such as freezing and rotating parts.

Quinoline is formed by various natural compounds, such as alkaloids from the cinchona plant, which exhibit various biological activities, and is an important building material for the development of new drugs. Quinoline can be used in anti-radiation drug development but radiation interaction properties must be determined.

In this study, six types of synthesized quinoline derivatives were used. Fast neutron removal cross-section, mean free path, half value layer and transmission number were theoretically determined by using GEometry ANd Tracking 4 and FLUktuierende KAskade simulation codes for neutron shielding. Neutron dose absorption rates were determined using the
Am-Be fast neutron source and the Canberra NP series portable BF
gas proportional neutron detector. Gamma radiation shielding parameters were determined by using WinXCom and PSY-X/PSD software. Additionally, the genotoxic potentials of the derivatives were assessed by using the Ames/
bacterial reversion assay.

Neutron shielding parameters such as removal cross-section, mean free path, half value layer and transmission number were theoretically determined for fast neutrons.
