Atmospheric transport modeling has been used to interpret the unprecedented number of multi-isotope detections of radioxenons observed during the six months of the qualification process by the Comprehensive Nuclear-Test-Ban Treaty Organization of the new SPALAX-NG system (Système de Prélèvement Automatique en Ligne avec l'Analyse du Xénon - Nouvelle Génération). Highest 133Xe activity concentrations were found to be systematically associated with the concomitant measurement of several other radioxenons at the prevailing wind direction of north/northeast pointing to the Institute for Radio Elements (IRE), a medical isotope production facility located in Fleurus (Belgium). The lowest 133Xe activity concentrations were not associated with a prevailing wind direction or other radioxenons, indicating the contribution of distant sources (global background). The IRE's average source terms for 133mXe and to a lesser extent for 133Xe (slightly overestimated by a factor of 1.7) showed good agreement with the literature values, while corrections by a factor of ~23 and ~53 were proposed for 131mXe and 135Xe since the initial values were underestimated. However, detections of 131mXe alone and some low-activity concentrations of 133Xe associated with only one of the other radioxenons could not be linked to the IRE releases. Analysis of these cases suggests the contribution of local source releases that have been difficult to identify to date. In addition to the global background, releases from such local sources, if not identified, could affect the analysis of the isotopic ratios measured following a nuclear test. The characterization of these local contributions is now possible owing to the capacity of the SPALAX-NG and other new generation measurements systems.
Symptomatic intracranial vertebro-basilar stenoses (SIVBS) are associated with high risk of recurrent ischemic stroke, even in patients receiving the best medical treatment. Although medical treatment is still the standard of care, non-responding patients may require endovascular treatment; balloon-mounted coronary stents (BMCS) could be successfully employed. This study aims to retrospectively analyze our high volume Interventional Neurovascular center ten-year experience in the off-label use of BMCS for the treatment of SIVBS, in order to assess its feasibility and safety.

We retrospectively analyzed all consecutive patients with SIVBS treated with BMCS in the last ten years in our center. Data collected included patient demographics, stenosis location and characteristics, early (<30 days) and late (>30 days) stroke and death rates, pre-symptomatic and post-treatment modified Rankin Scale (mRS) scores.

42 patients (35 males, average age 65,7±10,7, range 37-85) with SIVBS were treated with BMCS. Thirty-four (80,9%) patients were symptomatic despite ongoing best medical therapy; eight (19,1%) patients were treated in emergency for large vessel occlusion, due to an underlying stenosis. BMCSs were successfully deployed in all cases. The incidence of stroke and death at one month was 7,1% (3/42). The incidence of TIA, stroke and death at long-term follow-up (average time of 3 years) was 14,3% (4,7 per 100 person-years). At long-term follow-up, mRS improved in 82% of patients who underwent elective treatment.

In our experience, the off-label use of BMCS in the endovascular treatment of SIVBS resistant to medical treatment is feasible and safe.

The poor prognosis of acute stroke may be largely attributed to delays in treatment. Emergency medical services (EMS) usage is associated with a significant reduction in the delay in stroke treatment. The aims of this study were to identify factors associated with the delay in EMS activation for patients with acute stroke.

This study was conducted at 26 Fire Safety Centers in five districts of Seoul, Korea. Patients with acute stroke transferred by EMS and admitted to a tertiary referral hospital from January 2014 to December 2018 were enrolled. Phosphoramidon inhibitor In this cross-sectional study, the dependent variable was the time from stroke onset to EMS activation time. Patients were divided into two groups, onset-to-alarm time ≤ 30min and onset-to-alarm time > 30min, and previously collected patient data were analyzed. We performed logistical regression analyses of characteristics differing significantly between groups.

Out of 480 patients, 197 (41%) had onset-to-alarm times > 30min. Significant variables in the logistical analysis were alert mental state (adjusted odds ratio [aOR] 2.77; 95% confidence interval [CI] 1.31-6.13), pre-stroke mRS ≥ 2 (aOR 2.46; 95% CI 1.26-4.95), onset occurrence at private space (aOR 2.31; 95% CI 1.23-4.41), recognizing symptoms between 0 and 8 am (aOR 2.30; 95% CI 1.25-4.31), ischemic stroke (aOR 1.88; 95% CI 1.04-3.43), and witnessed by others (aOR 0.32; 95% CI 0.18-0.55).

Delay in EMS activation for acute stroke cases is possibly related to difficult situations to recognize stroke symptoms, such as alert mental state, pre-stroke mRS ≥ 2, onset occurrence at private space, recognizing symptoms between 0 and 8 am, and unwitnessed by others.

Hyper-responsiveness to clopidogrel abnormally inhibits platelet aggregation and increases hemorrhagic complications. The present study investigated clinical factors related to clopidogrel hyper-responsiveness in neuro-interventional procedures.

Two hundred twenty-four patients receiving clopidogrel for coil embolization to treat unruptured cerebral aneurysm or carotid artery stenting to treat carotid artery stenosis at the internal carotid artery origin were retrospectively reviewed for their P2Y12 reactivity unit (PRU) values and clinical characteristics. Hyper-responsiveness to clopidogrel was defined as a PRU of <95.

The mean PRU was 218.2±77.8. Hyper-responsiveness to clopidogrel was observed in 12 patients (5.4%). Hyper-responsiveness was observed in younger patients, patients with a lower concentration of hemoglobin A1c, and patients with a higher low-density lipoprotein cholesterol (LDL-C) concentration compared with non-hyper-responsive patients (P=0.01, P<0.01, P<0.01, respectively). On analysis of concomitant drugs, the patients in the hyper-responsive group were less frequently administered calcium channel blockers (CCBs) compared with the non-hyper-responsive group (P=0.
