Intravenous tissue-type plasminogen activator (tPA) is a proven treatment for acute ischemic stroke, but there has been limited evaluation among patients aged ≥90 years.', 'We analyzed data from the Get With The Guidelines-Stroke national quality improvement registry from January 2009 to April 2013. Frequency, determinants, and outcomes of tPA use were compared among patients aged ≥90 and 3 younger age groups (18-64, 65-79, and 80-89 years).', 'Among 35\u2009708 patients from 1178 sites who arrived within 2 hours of time last known well and received tPA, 2585 (7.2%) were ≥90 years. Compared with younger patients, the rate of tPA use among patients without a documented contraindication was lower among patients aged ≥90 years (67.4% versus 84.1% in 18-89-year olds; P<0.0001). Discharge outcomes among individuals aged ≥90 years included discharge to home or acute rehabilitation in 31.4%, independent ambulation at discharge in 13.4%, symptomatic hemorrhage in 6.1%, and in-hospital mortality or hospice discharge in 36.4%. On multivariable analysis, good functional outcomes generally occurred less often and mortality more often among patients aged ≥90 years. The risk of symptomatic hemorrhage was increased compared with patients <65 years but was not significantly different than the risk in 66- to 89-year olds.

Progression of pulmonary vascular disease limits heart transplantation for hypoplastic left heart syndrome (HLHS) to early infancy. Our objective was to assess the impact of bilateral pulmonary artery banding (PAB) on the operative courses of HLHS infants transplanted at ages older than 4 months.', 'Courses of all HLHS patients in our center who remained listed to age >or=120 days before heart transplantation were assessed. Patients undergoing transplantation after standard management (control group) were compared to patients having a prior pulmonary blood flow limiting procedure (PAB group).', 'Of 16 identified patients, one crossed over to stage I Norwood on day 185 and died post-operatively. Fifteen patients were transplanted at age >or=120 days (control group n=9, PAB group n=6). Four PAB patients had open PA band placement. Two PAB patients underwent experimental percutaneous bilateral internal pulmonary artery flow limiting device insertion. The PAB group mean age at banding was 141+/-54 days, and mean interval from PAB to transplant was 35+/-31 days (range 1.5-68 days). No differences in age at transplant, weight at transplant, warm graft ischemia time or total graft ischemia time were detected between groups. Mean times of mechanical ventilation (control 143+/-69h vs. PAB 44+/-13h), inhaled nitric oxide (control 126+/-70h vs. PAB 37+/-9h), inotropic support (control 171+/-64h vs. PAB 87+/-17h), intensive care unit (ICU) stay (control 8.3+/-2.7 days vs. PAB 4.5+/-1.4 days), and hospital stay (control 10.4+/-3.9 days vs. PAB 7.0+/-1.1 days) were all lower in the PAB group (P<0.05 all comparisons). Two control patients died, three required extracorporeal membrane oxygenation (ECMO), and six did not tolerate primary chest closure. No PAB patient died or required ECMO. All PAB patients tolerated primary chest closure. All PAB patients had widely patent branch pulmonary arteries with no re-interventions to date. All hospital survivors remain alive (mean follow-up, control 50.2 months, PAB 11.5 months).

Observational studies suggest that an association between vegetable consumption and coronary heart disease (CHD). However, the results are inconsistent. This study aimed to investigate the daily intake of vegetables on a national level and its effect on the risk of CHD risk, as determined by the Framingham Risk Score (FRS).', 'This study was conducted a cross-sectional design of 2,510 male adults 40-64y of age who participated in the 2007-2009 Korean National Health and Nutrition Examination Survey. Daily intake of vegetable was assessed by 24-h recall, and the consumption frequency of vegetables was determined using a food frequency questionnaire. The odd ratio of CHD risk according to daily intake and frequency of vegetables was analyzed.', 'Total vegetable intake was inversely and significantly associated with the risk of CHD (Model 1: 4th vs. 1st quartile, OR = 0.74, 95% CI = 0.58-0.96, P for trend = 0.0015), and the significant relationship with CHD risk remained even after adjusting for potential confounders (Model 3: 4th vs. 1st quartile, adjusted OR [aOR] = 0.69, 95% CI = 0.49-0.95, P for trend = 0.0492). Subjects in the higher quartiles of non-salted vegetable intake had 31% lower odds of the risk of CHD compared to those in the lowest quartile after adjusting for various potential confounders in model 3 (aOR = 0.69; 95% CI = 0.49-0.97, P for trend = 0.0478). No significant associations between the frequency of vegetable intake (total, green, white and red vegetable) and the risk of CHD were found.
