Nucleoside analogs are structurally, metabolically, and pharmacodynamically related agents that nevertheless have diverse biological actions and therapeutic consequences. This class of agents affects the structural integrity of DNA, generally after incorporation during replication or DNA excision repair synthesis, leading to stalled replication forks and(More)
BACKGROUND AND PURPOSE Endovascular treatments are being increasingly used in acute ischemic stroke, and better tools are needed to determine which patients may benefit most from these techniques. We hypothesized that specific chronic diseases can be used, along with age and stroke severity, to predict endovascular stroke treatment outcomes. MATERIALS AND(More)
OBJECTIVE To compare the safety and effectiveness of three methods of reversing coagulopathic effects of warfarin in patients with potentially life-threatening intracranial hemorrhage. METHODS A retrospective electronic medical record review of 63 patients with warfarin-related intracranial hemorrhage between 2007 and 2010 in an integrated health care(More)
IMPORTANCE Statin use during hospitalization is associated with improved survival and a better discharge disposition among patients with ischemic stroke. It is unclear whether inpatient statin use has a similar effect among patients with intracerebral hemorrhage (ICH). OBJECTIVE To determine whether inpatient statin use in ICH is associated with improved(More)
BACKGROUND AND PURPOSE Statins reduce infarct size in animal models of stroke and have been hypothesized to improve clinical outcomes after ischemic stroke. We examined the relationship between statin use before and during stroke hospitalization and poststroke survival. METHODS We analyzed records from 12 689 patients admitted with ischemic stroke to any(More)
Acute necrotizing encephalopathy (ANE) is a severe neurological complication of influenza infection, including H1N1 influenza. Many cases of ANE have been reported in the pediatric literature, but very few cases have been described in adults. The cause of ANE remains unknown-the influenza virus is not known to be neurotropic, and evidence of direct viral(More)
BACKGROUND AND PURPOSE Patients with cryptogenic ischemic stroke may have undetected paroxysmal atrial fibrillation (PAF). We established the Stroke and Monitoring for PAF in Real Time (SMART) Registry to determine the yield of 30-day outpatient PAF monitoring in cryptogenic ischemic stroke. METHODS The SMART Registry was a 3-year, prospective multicenter(More)
BACKGROUND AND PURPOSE Percutaneous dilatational tracheostomy (PDT) continues to gain in popularity as a bedside method for tracheostomy placement in the intensive care unit. Here, we present a description of ultrasound technique and two case examples to show the utility of bedside ultrasound screening to select patients with appropriate anatomy for PDT. (More)
BACKGROUND External ventricular drains (EVDs) are associated with high rates of infection, and EVD infections cause substantial morbidity and mortality. OBJECTIVE To determine whether the introduction of an evidence-based EVD infection control protocol could reduce the rate of EVD infections. METHODS This was a retrospective analysis of an EVD infection(More)
OBJECTIVE To determine whether statin use is associated with improved discharge disposition after ischemic stroke. METHODS We used generalized ordinal logistic regression to analyze discharge disposition among 12,689 patients with ischemic stroke over a 7-year period at 17 hospitals in an integrated care delivery system. We also analyzed treatment(More)
