Data from an International Multi-Centre Study of Statistics and Mathematics Anxieties and Related Variables in University Students (the SMARVUS Dataset)

This large, international dataset contains survey responses from N = 12,570 students from 100 universities in 35 countries, collected in 21 languages. We measured anxieties (statistics, mathematics, test, trait, social interaction, performance, creativity, intolerance of uncertainty, and fear of negative evaluation), self-efficacy, persistence, and the cognitive reflection test, and collected demographics, previous mathematics grades, self-reported and official statistics grades, and statistics module details. Data reuse potential is broad, including testing links between anxieties and statistics/mathematics education factors, and examining instruments’ psychometric properties across different languages and contexts

CT diagnosis of cerebral venous thrombosis: importance of the first examination fast treatment.

This study is a retrospective investigation of the role of non contrast-enhanced CT (NCCT) in the diagnosis of cerebral venous thrombosis (CVT) in clinical practice. We retrospectively identified 24 patients discharged with a diagnosis of CVT between January 2002 and December 2008 who had undergone NCCT as the first imaging modality. NCCT had been evaluated by a general radiologist and subsequently by a neuroradiologist in five cases. Final diagnosis was established by CT angiography (CTA), magnetic resonance (MR) and digital subtraction angiography (DSA). NCCT diagnosis was defined as "positive" when the neuroradiologist suggested the diagnosis of CVT on the report, as opposed to the "negative" diagnosis group. All NCCT examinations were reviewed by a neuroradiologist experienced in cerebrovascular pathology. We compared his evaluation and analysed the location and number of direct signs found on NCCT. The neuroradiologist strongly suggested an NCCT diagnosis of CVT in 63% (15/24) of patients: 80% (4/5) with deep venous thrombosis (DVT) and 57% (11/19) with sinus venous thrombosis (SVT). The general radiologist's NCCT evaluation was incorrect in four cases, subsequently diagnosed at NCCT by the neuroradiologist. After reviewing the NCCT examination the experienced neuroradiologist identified the CVT direct sign in two that belonged to the NCCT negative diagnosis group. Thus the direct sign was present in 71% (17/24) of the cases: all the patients with DVT and 63% (12/19) of the patients with SVT. NCCT still plays an important role for fast and accurate diagnosis of CVT in the emergency setting. NCCT displayed the CVT direct sign more frequently than previously thought and it was correctly interpreted in most cases. Neuroradiological consultation adds value to the general radiologist's evaluation

Target balloon-assisted antegrade and retrograde use of re-entry catheters in complex chronic total occlusions

Purpose, Retrograde recanalizations have gained increasing recognition in complex arterial occlusive disease. Re-entry devices are a well described adjunct for antegrade recanalizations. We present our experience with target balloon-assisted antegrade and retrograde recanalizations using re-entry devices in challenging chronic total occlusions. MATERIALS AND METHODS: We report data from a retrospective multicenter registry. Eligibility criteria included either antegrade or retrograde use of the OutbackTM or GoBackTM re-entry catheter in combination with a balloon as a target to accomplish wire passage, when conventional antegrade and retrograde recanalization attempts had been unsuccessful. Procedural outcomes included technical success (defined as wire passage though the occlusion and delivery of adjunctive therapy with <30% residual stenosis at final angiogram), safety (periprocedural complications, e.g., bleeding, vessel injury, or occlusion of the artery at the re-entry site, and distal embolizations), and clinical outcome (amputation-free survival and freedom from target lesion revascularization after 12-months follow-up). RESULTS: Thirty-six consecutive patients underwent target balloon-assisted recanalization attempts. Fourteen (39 %) patients had a history of open vascular surgery in the index limb. Fifteen patients were claudications (Rutherford Class 2 or 3, 21 presented with chronic limb threatening limb ischemia (Rutherford Class 4 to 6). The locations of the occlusive lesions were as follows: iliac arteries in 3 cases, femoropopliteal artery in 39 cases, and in below-the-knee arteries in 12 cases. In 15 cases, recanalization was attempted in multilevel occlusions. Retrograde access was attempted in 1 case in the common femoral artery, in the femoropopliteal segment in 10 cases, in below-the-knee arteries in 23 cases, and finally in 2 patients via the brachial artery. In 10 cases, the re-entry devices were inserted via the retrograde access site. Technical success was achieved in 34 (94 %) patients. There were 3 periprocedural complications, none directly related to the target balloon-assisted re-entry maneuver. Amputation-free survival was 87.8 % and freedom from clinically driven target lesion revascularization was 86.6 % after 12-months follow-up. CONCLUSION: Target balloon-assisted use of re-entry devices in chronic total occlusions provides an effective and safe endovascular adjunct, when conventional antegrade and retrograde recanalization attempts have failed
