A systematic review of the association between depression and health care utilization in children and adults with sickle cell disease.

Patients with sickle cell disease (SCD) experience a disproportionately high use of health care resources. Several studies have examined depression and other negative mood states as risk factors for increased health care utilization; however, there have been no systematic reviews examining and summarizing this evidence in SCD. The aim of this systematic review, therefore, was to determine whether depression or depressive symptoms are associated with health care utilization among children and adults with SCD.

Factors associated with non-adherence to Buprenorphine-naloxone among opioid dependent African-Americans: A retrospective chart review.

Background And Objectives: Opioid use disorders are common, chronic relapsing disorders. Buprenorphine (BUP) is an FDA approved medication in the treatment of opioid use disorders, but patient adherence to this medication remains a challenge. To identify risk factors for non-adherence, this chart review study examined the association between DSM-IV Axis I psychiatric disorders, substance use, demographics, and adherence to BUP-naloxone in African-American patients.

Neuronal tryptophan hydroxylase expression in BALB/cJ and C57Bl/6J mice.

BALB/c is an inbred stress-sensitive mouse strain exhibiting low brain serotonin (5-HT) content and a 5-HT biosynthetic enzyme tryptophan hydroxylase (Tph2) variant reported to have lower catalytic activity compared with other inbred base strains. To evaluate other mechanisms that may explain low 5-HT, we compared BALB/cJ mice and a control inbred strain C57Bl/6J mice, for expression of Tph2 mRNA, TPH2 protein and regional levels of 5-HT and its metabolite 5-hydroxyindoleacetic acid. Tph2 mRNA and TPH2 protein in brainstem dorsal raphe nuclei was assayed by in situ hybridization and immunocytochemistry respectively.
