Introduction: This document provides an update to the 2015 consensus statement with new content on inpatient utilization, procedural data, and compensation. The full document is available on the American Urological Association (AUA) website (https://www.auanet.

Tenecteplase versus Alteplase before Thrombectomy for Ischemic Stroke.

Background: Intravenous infusion of alteplase is used for thrombolysis before endovascular thrombectomy for ischemic stroke. Tenecteplase, which is more fibrin-specific and has longer activity than alteplase, is given as a bolus and may increase the incidence of vascular reperfusion.

Methods: We randomly assigned patients with ischemic stroke who had occlusion of the internal carotid, basilar, or middle cerebral artery and who were eligible to undergo thrombectomy to receive tenecteplase (at a dose of 0.

A Right Intercosto-Bronchial Artery Derived from the Thyrocervical Trunk: An Unusual Cause of Type II Endoleak Post Thoracic Aortic Stenting.

The aetiology, incidence and management of type II endoleaks in standard infrarenal endovascular aortic aneurysm repair is well described. Far less data is available for thoracic stent grafting. We present a rare and interesting case of a type II endoleak post thoracic aortic stenting and highlight the aberrant anatomy that can cause this phenomenon in such cases.

Vertebrobasilar dissections: case series comparing patients with and without dissecting aneurysms.

Vertebrobasilar dissections are being increasingly diagnosed due to better awareness and increased availability of modern imaging techniques of the intracranial and extracranial arteries. The clinical presentation and outcome in patients with vertebrobasilar dissections may be complicated by dissecting aneurysms. The aim of this retrospective study was to compare the clinical profile of patients with vertebrobasilar dissections with and without dissecting aneurysms, and to determine predisposing factors to the development of aneurysms.

Safety and efficacy of oral DMSA therapy for children with autism spectrum disorders: part B - behavioral results.

Background: This study investigated the effects of oral dimercapto succinic acid (DMSA) therapy on the behavioural symptoms of children with autism spectrum disorders (ASD) ages 3-8 years.

Methods: Phase 1 involved 65 children with ASD who received one round of DMSA (3 days). Participants who had high urinary excretion of toxic metals were selected to continue on to phase 2.

Safety and efficacy of oral DMSA therapy for children with autism spectrum disorders: Part A--medical results.

Background: This study investigated the effect of oral dimercapto succinic acid (DMSA) therapy for children with autism spectrum disorders ages 3-8 years.

Methods: Phase 1 involved 65 children who received one round of DMSA (3 days). Participants who had high urinary excretion of toxic metals were selected to continue on to phase 2.

More than one dilemma.

We present an unusual case that highlights a number of management dilemmas: the cause, investigation and treatment of subarachnoid hemmorrhage in patients iwth vascular connective tissue diseases; the further investigation of small aneurysms identified on CT angiography; and the difficulties associated with anticoagulation, mechanical cardiac valves and cerebral hemorrhage.

Regions of strong coupling between soil moisture and precipitation.

Previous estimates of land-atmosphere interaction (the impact of soil moisture on precipitation) have been limited by a lack of observational data and by the model dependence of computational estimates. To counter the second limitation, a dozen climate-modeling groups have recently performed the same highly controlled numerical experiment as part of a coordinated comparison project. This allows a multimodel estimation of the regions on Earth where precipitation is affected by soil moisture anomalies during Northern Hemisphere summer.

Intraorbital ophthalmic artery aneurysms.

Angiographically documented aneurysms of the intraorbital ophthalmic artery are extremely rare. Two cases are presented of intra-orbital ophthalmic artery aneurysms, both associated with arteriovenous malformation (AVM). There have only been isolated reports documenting this combination of vascular anomalies.

Comparison of vehicle exhaust emissions from modified diesel fuels.

Three diesel fuels, one oil sand-derived (OSD) diesel serving as base fuel, one cetane-enhanced base fuel, and one oxygenate [diethylene glycol dimethyl ether (DEDM)]-blended base fuel, were tested for their emission characterizations in vehicle exhaust on a light-duty diesel truck that reflects the engine technology of the 1994 North American standard. Both the cetane-enhanced and the oxygenate-blended fuels were able to reduce regulated [CO, particulate matter (PM), total hydrocarbon (THC)] and nonregulated [polyaromatic hydrocarbons (PAHs), carbonyls, and other volatile organic chemicals] emissions, except for nitrogen oxides (NO(x)), compared with the base fuel. Although burning a fuel that contains oxygen could conceivably yield more oxygenated compounds in emissions, the oxygenate-blended diesel fuel resulted in reduced emissions of formaldehyde along with hydrocarbons such as benzene, 1,3-butadiene, and PAHs.
