Question: It is still debatable whether anemia predicts stroke outcome.', 'To describe the characteristics of patients with acute ischemic stroke (AIS) and anemia and identify whether hemoglobin status on admission is a prognostic factor of AIS outcome.', 'All 2439 patients of the Acute Stroke Registry and Analysis of Lausanne (ASTRAL) between January 2003 and June 2011 were selected. Demographics, risk factors, prestroke treatment, clinical, radiological and metabolic variables in patients with and without anemia according to the definition of the World Health Organization were compared. Functional disability and mortality were recorded up to 12 months from admission.', 'Anemic patients (17.5%) were older, had lower body mass index, higher rates of coronary artery disease (CAD), atrial fibrillation, diabetes mellitus and peripheral artery disease. Anemia was associated with more severe stroke manifestations, lower systolic and diastolic blood pressure measurements, worse estimated glomerular filtration rate and elevated C-reactive protein concentrations upon admission and with increased modified Rankin scores during the follow-up. Anemic patients had higher 7-day, 3-month and 12-month mortality, which was associated with hemoglobin status and other factors, including age, CAD, stroke severity, and baseline C-reactive levels. Hemoglobin levels were inversely associated with recurrent stroke and mortality throughout the 12-month follow-up.

Question: Clinical studies demonstrate increased prevalence of human papillomavirus (HPV)-associated disease in HIV-infected individuals and an increased risk of HIV acquisition in HPV-infected individuals. The mechanisms underlying this synergy are not defined. We hypothesize that women with cervical intraepithelial neoplasia (CIN) will exhibit changes in soluble mucosal immunity that may promote HPV persistence and facilitate HIV infection.', 'The concentrations of immune mediators and endogenous anti-Escherichia coli activity in genital tract secretions collected by cervicovaginal lavage were compared in HIV-negative women with high-risk HPV-positive (HRHPV+) CIN-3 (n = 37), HRHPV+ CIN-1 (n = 12), or PAP-negative control subjects (n = 57).', 'Compared with control subjects, women with CIN-3 or CIN-1 displayed significantly higher levels of proinflammatory cytokines including interleukin (IL)-1α, IL-1β, and IL-8 (P < 0.002) and significantly lower levels of anti-inflammatory mediators and antimicrobial peptides, including IL-1 receptor antagonist, secretory leukocyte protease inhibitor (P < 0.01), and human β defensins 2 and 3 (P < 0.02). There was no significant difference in endogenous anti-E. coli activity after controlling for age and sample storage time.

Question: Although early primary repair of tetralogy of Fallot has gained wider acceptance, there is some speculation that repair at a younger age may be associated with increased morbidity and resource utilization.', 'A retrospective review of all consecutive patients undergoing tetralogy of Fallot repair between September 2004 and December 2011 was performed. Primary end points were hospital charges, and surrogates of postoperative hospital resource utilization, including ventilation time, intensive care unit (ICU) stay, and hospital stay. The secondary end point was operative death. Logistic regression analysis was used to determine factors associated with increased postoperative hospital resource utilization.', 'Among 164 patients in the study, there was 1 hospital death (0.6%). After excluding 9 patients who had palliative procedures before their repair, 155 comprised the primary repair group. Multivariate linear regression analysis revealed prematurity (p\xa0= 0.018), a nonelective operation (p < 0.001), and major extracardiac anomalies (p\xa0= 0.003) were independent predictors of increased postoperative hospital charges. Prematurity (p < 0.002), low birth weight (p\xa0= 0.047), and major extracardiac anomalies (p < 0.001) were significant predictors of increased ventilation time. Prematurity (p < 0.001), a nonelective operation (p < 0.001), and low birth weight (p\xa0= 0.048) significantly increased ICU length of stay. A nonelective operation (p\xa0= 0.025) and major extracardiac anomalies (p < 0.001) were predictors of an increased hospital stay. Younger age at repair was not associated with any increase in ventilation time, ICU stay, hospital stay, or with an increase in hospital charges.
