Spontaneous bacterial peritonitis (SBP) is a severe complication of liver disease. A significant proportion of patients have culture-negative ascites, despite having similar signs, symptoms and mortality to those with SBP. Therefore, empirical antibiotic treatment for infection is often started without knowledge of the causative organisms. Here, we(More)
The principal cause of morbidity and mortality in cystic fibrosis is persistent respiratory colonization with mucoid strains of Pseudomonas aeruginosa. To investigate possible mechanisms of resistance to this organism, we studied serum from 16 older (greater than or equal to 12 years) patients not colonized with mucoid P. aeruginosa, 11 older (greater than(More)
The Pseudomonas aeruginosa-derived phenazine pigments pyocyanin and 1-hydroxyphenazine (1-hp) prime human neutrophils for enhanced, stimulus-activated release of superoxide and myeloperoxidase (MPO), respectively. In the present study, the modulatory potentials of the antimicrobial agents clindamycin, erythromycin, and roxithromycin (10 and 20(More)
OBJECTIVES We examined the effect of mechanical unloading with ventricular assist device (VAD) therapy on myocardial inducible nitric oxide synthase (iNOS) expression and cardiomyocyte apoptosis in patients with end-stage heart failure (HF). BACKGROUND Despite advances in medical therapy, HF continues to be a progressive and ultimately fatal disorder.(More)
OBJECTIVE To examine potential differences in psychiatric symptoms between parent-bereaved youth (N = 172), youth who experienced the death of another relative (N = 815), and nonbereaved youth (N = 235), aged 11 to 21 years, above and beyond antecedent environmental and individual risk factors. METHOD Sociodemographics, family composition, and family(More)
This study was designed to verify the in vivo efficacy of sulfoxide and sulfone fexinidazole metabolites following oral administration in a murine model of Chagas disease. Female Swiss mice infected with the Y strain of Trypanosoma cruzi were treated orally once per day with each metabolite at doses of 10 to 100 mg/kg of body weight for a period of 20 days.(More)
