OBJECTIVE To examine in vivo glutamatergic neurochemical alterations in the anterior cingulate cortex of pediatric patients with obsessive-compulsive disorder (OCD) without major depressive disorder (MDD) versus pediatric patients with MDD without OCD and healthy controls. METHOD Single-voxel proton magnetic resonance spectroscopic examinations of the(More)
OBJECTIVE To examine in vivo glutamatergic neurochemical alterations in the anterior cingulate cortex of children with major depressive disorder (MDD). METHOD Single-voxel proton magnetic resonance spectroscopic (H-MRS) examinations of the anterior cingulate cortex were conducted in 13 psychotropic-naïve children and adolescents with MDD and 13 age- and(More)
OBJECTIVE To compare outcomes for patients with hepatocellular carcinoma (HCC) treated with either liver resection or transplantation. METHODS A retrospective, single-institution analysis of 413 HCC patients from 1999 to 2009. RESULTS A total of 413 patients with HCC underwent surgical resection (n = 106) and transplantation (n = 270) or were listed(More)
OBJECTIVES This study evaluated the effectiveness of a community youth service (CYS) program in reducing sexual risk behaviors among African American and Latino urban young adolescents. METHODS A total of 1061 students at 2 urban middle schools were surveyed at baseline and 6-month follow-up. Students at one school were randomly assigned by classroom to(More)
BACKGROUND Misoprostol, a prostaglandin E1 analog, stimulates uterine contractility and cervical ripening. A number of randomized trials and systematic reviews have evaluated its use in obstetric and gynecologic conditions. Misoprostol is inexpensive, stable at room temperature, and available in more than 80 countries, making it particularly useful in(More)
The objectives of this study were to describe the most recent pregnancy intentions and family planning preferences of HIV-infected and HIV-uninfected postpartum Malawian women, and to assess whether HIV status is associated with fertility desire and knowledge of intrauterine contraception (IUC) and the subdermal contraceptive implant. We conducted a(More)
One of the hallmarks of Alzheimer's disease is the formation of protein plaques in the brain, which mainly consist of amyloid-β peptides of different lengths. While the role of these plaques in the pathology of the disease is not clear, the mechanism behind peptide aggregation is a topic of intense research and discussion. Because of their simplicity,(More)
Hormonal contraception is central in the prevention of unintended pregnancy; however there are concerns that certain methods may increase the risk of HIV acquisition and transmission. Hormonal contraceptives may modify the genital mucosa in several ways, however the mechanisms are incompletely understood. Few studies have examined genital HIV shedding(More)
OBJECTIVE To assess why postpartum women who desired long-acting reversible contraception (LARC) did not receive it in the postpartum period and to assess which contraceptive methods they were using instead. STUDY DESIGN This was a subgroup analysis of 324 women enrolled in a randomized, controlled trial to receive or not receive an educational LARC(More)
Proton magnetic resonance spectroscopy (1H-MRS) studies of schizophrenia suggest an effect of the disease or of antipsychotic medications on brain N-acetyl aspartate (NAA), a marker of neuronal viability. We studied in rat the effect of haloperidol on NAA, glutamate, and glutamine in several brain regions where metabolite reductions have been reported in(More)
