Factors associated with treatment initiation for psychiatric and substance use disorders among persons with HIV.
ObjectivePrior studies of individuals with HIV infection have found that accessing psychiatric and substance abuse treatment when needed can improve health and prolong life, yet little is known about factors associated with treatment initiation.MethodsIn a retrospective cohort design including individuals with HIV infection (≥14 years old) in an integrated health care system in Northern California, this study included 822 patients with a major psychiatric diagnosis and 1,624 with a substance use disorder diagnosis. Data were extracted from a regional HIV registry and computerized databases.ResultsTwenty-four percent (N=198) of study patients with psychiatric diagnoses and 15% (N=245) with substance abuse or dependence received one or more specialty care visits within 12 months of diagnosis. Among patients with a psychiatric diagnosis, significant predictors of visiting a psychiatry clinic included not having an AIDS diagnosis at baseline or before the study (p=.049), having a diagnosis of major depression (p=.013), having a diagnosis of bipolar disorder (p<.001), and receiving a psychiatric diagnosis in 1996 versus later years of the study (p<.01). Among patients with a substance use disorder, significant predictors of initiating substance abuse treatment included age <30 (p=.015) and being in the HIV transmission risk group of injection drug use (p<.001).ConclusionsClinical, diagnostic, and demographic factors were associated with specialty care treatment initiation in this sample of individuals with HIV infection and substance use or psychiatric disorders. Developing strategies to enhance treatment initiation has the potential to improve outcomes for individuals with HIV infection
Factors Associated With Treatment Initiation for Psychiatric and Substance Use Disorders Among Persons With HIV
Luteolin Isolated from the Medicinal Plant Elsholtzia rugulosa (Labiatae) Prevents Copper-Mediated Toxicity in β-Amyloid Precursor Protein Swedish Mutation Overexpressing SH-SY5Y Cells
Luteolin, a 3’,4’,5,7-tetrahydroxyflavone, is a plant flavonoid and pharmacologically active agent that has been isolated from several plant species. In the present study, the effects of luteolin obtained from the medicinal plant Elsholtzia rugulosa and the related mechanisms were examined in an Alzheimer's disease (AD) cell model. In this model, copper was used to exacerbate the neurotoxicity in β-amyloid precursor protein Swedish mutation stably overexpressed SH-SY5Y cells (named “APPsw cells” for short). Based on this model, we demonstrated that luteolin increased cell viability, reduced intracellular ROS generation, enhanced the activity of SOD and reversed mitochondrial membrane potential dissipation. Inhibition of caspase-related apoptosis was consistently involved in the neuroprotection afforded by luteolin. Furthermore, it down-regulated the expression of AβPP and lowered the secretion of Aβ1-42. These results indicated that luteolin from the Elsholtzia rugulosa exerted neroprotective effects through mechanisms that decrease AβPP expression, lower Aβ secretion, regulate the redox imbalance, preserve mitochondrial function, and depress the caspase family-related apoptosis
