2001 Text Retrieval Conference  
For TREC-10, we participated in the adhoc and manual web tracks and in both the site-finding and cross-lingual tracks. For the adhoc track, we did extensive calibrations and learned that combining similarity measures yields little improvement. This year, we focused on a single highperformance similarity measure. For site finding, we implemented several algorithms that did well on the data provided for calibration, but poorly on the real dataset. For the cross-lingual track, we calibrated on the

2008 Circulation  
Background-The clinical efficacy of alcohol septal ablation for drug-refractory hypertrophic cardiomyopathy remains unclear. This study examines the outcome of alcohol septal ablation performed at a tertiary hypertrophic cardiomyopathy referral center. Methods and Results-Among 601 patients with severely symptomatic obstructive hypertrophic cardiomyopathy referred for alcohol septal ablation or myectomy from 1998 to 2006, 138 patients (median age, 64 years; 39% men) chose to undergo ablation.
more » ... ocedural complications included death in 1.4%, sustained ventricular arrhythmias in 3%, tamponade in 3%, and pacemaker implantation in 20%. This rate was higher than a combined complication rate of 5% in age-and gender-matched patients who had undergone septal myectomy at Mayo Clinic (PϽ0.0001). Four-year survival free of all mortality was 88.0% (95% confidence interval, 79.4 to 97.5%), which was similar to that of the age-and gender-matched patients who had undergone myectomy (Pϭ0.18). Six patients had documented ventricular arrhythmias after ablation, 4 of whom had successful intervention. Four-year survival free of death and severe New York Heart Association class III/IV symptoms after septal ablation was 76.4%, and 71 patients (51%) became asymptomatic. Myectomy patients Յ65 years of age had significantly better survival free of death and severe symptoms (Pϭ0.01). Conclusions-Alcohol septal ablation is an efficacious procedure if performed in an experienced institution and may resolve symptoms in a subset of patients with obstructive hypertrophic cardiomyopathy. However, the procedural complication rate exceeds that of myectomy. Patients Յ65 years of age have better symptom resolution with myectomy. No impairment in short-term survival was noted in this nonrandomized study, but the long-term outcome remains unknown. (Circulation. 2008;118:131-139.)

Incidence, associations, and evaluation of sixth nerve palsy using a population-based method

Purpose: To determine the incidence of sixth nerve palsy in a population-based study, with particular emphasis on associated coexisting medical conditions and to use these data to develop a management algorithm. Design: Retrospective, population-based case series. Participants: All residents of Olmsted County, Minnesota, USA, diagnosed with sixth nerve palsy between January 1, 1978 and December 31, 1992. Methods: All cases were identified by using the Rochester Epidemiology Project medical
more » ... ds linkage system, which captures all patient-physician encounters in Olmsted County. The entire medical record of each patient was reviewed to confirm the diagnosis, document county residency, and to determine associated medical conditions. We used stringent predetermined criteria to define diabetes mellitus and hypertension as associations. Incidence rates were adjusted to the age and gender distribution of the 1990 white population in the United States. Main Outcome Measures: Etiology or systemic associations of the palsy. Results: We identified 137 new cases of sixth nerve palsy over the 15-year period. The age-and genderadjusted annual incidence of sixth nerve palsy was 11.3/100 000 (95% confidence interval, 9.3-13.2/100 000). Causes and associations were: undetermined (26%), hypertension alone (19%), coexistent hypertension and diabetes (12%), trauma (12%), multiple sclerosis (7%), neoplasm (5%), diabetes alone (4%), cerebrovascular accident (4%), postneurosurgery (3%), aneurysm (2%), and other (8%). When sixth nerve palsy was the presenting sign in cases of neoplasm (n ϭ 1) and aneurysm (n ϭ 3), history and examination revealed the presence of other neurologic symptoms or signs. Conclusions: We provide population-based data on the incidence of sixth nerve palsy with a notably lower incidence of neoplasm and higher incidence of diabetes and hypertension than previous institution-based series. We suggest that patients with nontraumatic neurologically isolated sixth nerve palsy may undergo a focused medical evaluation followed by close observation, whereas non-neurologically isolated cases warrant a full neurologic evaluation, including prompt neuroimaging.

2002 Journal of the American College of Cardiology  
OBJECTIVES The goal of this study was to determine whether women undergoing contemporary percutaneous coronary intervention (PCI) remain at increased risk in comparison with men and whether the outcomes in women have improved. BACKGROUND Previous studies have shown that women treated with coronary angioplasty have a higher incidence of procedural morbidity and mortality than men. METHODS Gender differences in wave 1 of the National Heart, Lung and Blood Institute (NHLBI) Dynamic registry were

Baseline characteristics and outcomes in women in the Dynamic registry were compared with those in women in the 1985-1986 and 1993-1994 NHLBI Percutaneous Transluminal Coronary Angioplasty (PTCA) registries. RESULTS Women were older with a higher prevalence of diabetes mellitus, hypertension, congestive heart failure, unstable angina and single vessel disease in comparison with men. Although procedural success and in-hospital death (2.2% vs. 1.3%), myocardial infarction (MI) (2.3% vs. 3.0%) and coronary artery bypass graft surgery (CABG) (1.3% vs. 1.4%) were similar in women and men, respectively, one-year mortality (6.5% vs. 4.3%, p ϭ 0.02) and combined end point of death/MI/CABG (18.3% vs. 14.4%, p ϭ 0.03) were higher in women than in men. After controlling for other factors, gender was not a significant predictor of death or death plus MI at one year. Despite a higher risk profile in women in the Dynamic registry in comparison with women in the 1985-1986 NHLBI PTCA registry, in-hospital death/MI/ CABG was lower (6.0% vs. 11.6%, p Ͻ 0.001). CONCLUSIONS Despite persistent high-risk characteristics in women, gender differences in outcomes in patients undergoing contemporary PCI have decreased, and outcomes in women have improved. (J Am
