BACKGROUND To test the effectiveness and safety of omega-3 fatty acids (Omegabrite(R) brand) in the treatment of pediatric bipolar disorder (BPD). METHOD Subjects (N=20) were outpatients of both sexes, 6 to 17 years of age, with a DSM-IV diagnosis of BPD and Young Mania Rating Scale (YMRS) score of >15 treated over an 8-week period in open-label trial(More)
We examined the antidepressant efficacy and dose-response pattern of the n-3 docosahexaenoic acid (DHA). Thirty-five depressed adult outpatients (46% women; mean age 42+/-14 years) with a 17-item Hamilton-Depression Scale (HAM-D-17) score of >or=18 were randomized into one of three double-blind dosing arms for 12 weeks. Group A (n=14): 1 g/day of oral DHA;(More)
The aim of the study was to determine whether fatty acid ethyl esters, nonoxidative products of ethanol metabolism selectively present in organs damaged by ethanol abuse, are detectable in the serum after ethanol ingestion. Serum samples of hospital emergency room patients with positive (n = 32) and negative (n = 5) blood ethanol levels were assayed for(More)
Cystic fibrosis (CF) is caused by a mutation of the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR). We examined platelet function in CF patients because lung inflammation is part of this disease and platelets contribute to inflammation. CF patients had increased circulating leukocyte-platelet aggregates and increased platelet(More)
Clinician attitudes toward multiplexed genomic testing may be vital to the success of translational programs. We surveyed clinicians at an academic medical center about their views on a large pharmacogenomics implementation, the PREDICT (Pharmacogenomic Resource for Enhanced Decisions in Care and Treatment) program. Participants were asked about test(More)
Although alcohol abuse is known to cause an array of ethanol-induced red blood cell (RBC) abnormalities, the underlying molecular mechanisms remain poorly understood. Fatty acid ethyl esters (FAEEs) are toxic, nonoxidative ethanol metabolites that have been found in blood, plasma, and tissues. Because FAEEs have been shown to be incorporated into(More)
Patients with cystic fibrosis (CF) exhibit characteristic polyunsaturated fatty acid abnormalities, including low linoleic acid and high arachidonic acid levels that are thought to contribute to the pathophysiology of this disease. Recent studies indicate that changes in fatty acid metabolism are responsible for these abnormalities. This study examines the(More)
Fatty acid ethyl esters (FAEE), esterification products of fatty acid and ethanol, have been implicated as mediators of ethanol-induced organ damage. To understand the molecular and cellular events in FAEE synthesis and secretion, we developed a system in which HepG2 cells synthesize and release FAEE into the culture medium upon incubation with ethanol. The(More)
