This is the first report of proteomic alterations following embryonic exposure to atrazine, an environmentally persistent pesticide and common water contaminant. Although the transcriptomic alterations in larval zebrafish with embryonic atrazine exposure have been reported, neither the time at which gene expression changes occur nor the resulting proteomic changes have been investigated. This study seeks to address these knowledge gaps by evaluating atrazine's effect on gene expression through multiple time points during embryogenesis, and correlating changes in gene expression to pathological alterations in brain length and functional changes in behavior. Finally, pathway analysis of the proteomic alterations identifies connections between the molecular changes and functional outcomes associated with embryonic atrazine exposure.

Introduction The office-based endovascular facility has increased in number recently due in part to expedient patient experience. This study analyzed treatment outcomes of procedures performed in our office-based endovascular suite. Methods Treatment outcomes of 5134 consecutive procedures performed in our office-based endovascular suites from 2006 to 2013 were analyzed. Five sequential groups (group I-V) of 1000 consecutive interventions were compared with regard to technical success and treatment outcomes. Results Our patients included 2856 (56%) females and 2267 (44%) males. Procedures performed included diagnostic arteriogram, arterial interventions, venous interventions, dialysis access interventions, and venous catheter management, which were 1024 (19.9%), 1568 (30.6%), and 3073 (60.0%), 621(12.1%), and 354 (6.9%), respectively. The complication rates for group I, II, III, IV, and V were 3%, 1.5%, 1%, 1.1%, and 0.7%, respectively. The complication rate was higher in group I when compared to each of the remaining four groups ( p < 0.05). Nine patients (0.18%) died within the 30-day period following their procedures, and none were procedure related. Conclusions Endovascular procedure can be performed safely in an office-based facility with excellent outcomes. Lessons learned in establishing office-based endovascular suites with efforts to reduce procedural complications and optimize quality patient care are discussed.
