OBJECTIVES: Social network analysis can provide added causal insight into otherwise confusing epidemiologic findings in public health research. Although foster care and homelessness are risk factors for methamphetamine use, current research has failed to explicate why homeless youth with foster care experience engage in methamphetamine use at higher rates than other homeless young adults. This study examined the mediating effect of network engagement and time spent homeless on the relationship between foster care experience and recent methamphetamine use among homeless youth in Los Angeles...

The role of platelets in the neurological diseases that underlie cognitive impairment has attracted increasing attention in recent years. Multiple pathways in platelets contribute to host defenses, as well as to CNS function. In the current study, we hypothesize that the Blood Brain Barrier (BBB) is disrupted when exposed to platelets from patients with triple Co-morbidity (hazardous alcohol users+ HIV+ thrombocytopenia), compared to those with dual, single or no morbidity (HIV only, alcohol only or healthy controls)...

Due to the legalization of marijuana and the increased demand for cannabis and alcohol consumption, research efforts highlighting the biomedical consequences of the use of alcohol and cannabinoids are not only relevant to the substance abuse scientific field, but are also of public health interest. Moreover, an overview of the recent literature about alcohol and cannabinoids neuro-immunomodulatory effects highlighting their future therapeutic potentials will provide a significant contribution to science and medicine...

A series of studies by Drs. Barak Caine, James Woods, Gregory Collins, Jonathan Katz and Takato Hiranita demonstrated a novel and unique reinforcing effect using dopamine (DA) D2-like receptor [D2-like R: D2, D3, and D4 receptor subtypes (respectively, D2R, D3R, and D4R)] agonists in rats and genetically modified mice. In order to understand how important their findings are, a comparison was made regarding the reinforcing effects of DA D2-like R full agonists with those of DA uptake inhibitors and of a DA D1-like receptor [D1-like R, D1 and D5 receptor subtypes (D1R and D5R)] full agonist (±)-SKF 82958...

There are a variety of self-help treatments which have components of sponsorship or peer support. Although there has been a recent surge in the utilization of peer support interventions within clinical settings, there is limited data on substance use outcome predictors for interventions designed solely for peer support within community treatment settings that are empirically based. We examined both treatment process and participant characteristic variables as predictors of substance use outcomes within our Stage I pilot which developed a new intervention, Mentorship for Addiction Problems (MAP)...

BACKGROUND: Despite the excessive rates of Hazardous Alcohol Use (HAU) among people living with HIV (PLWH), although largely speculated, psychological and physiological components associated with HAU, has not been actively measured. Therefore, the present study was geared toward determining: 1) the rates of mood disorders and its relationship with HAU, and 2) to assess the impact of Brain Derived Neurotrophic Factor (BDNF), a well-known regulator of alcohol and mood disorders. METHODS: For this study, participants of the longitudinal PADS Study n=400, were followed over time...

Alcoholism frequently occurs in returning U.S. Veterans, and is often comorbid with Post Traumatic Stress Disorder (PTSD). The goal of this study was to investigate the relationship between white matter changes and neuropsychological alterations in Operation Enduring Freedom, and/or Operation Iraqi Freedom (OEF/OIF) alcoholic Veterans with two primary aims: (1) to examine the relationship of alcoholism to brain structure and function while controlling for the potential effects of comorbid PTSD, and (2) to examine whether the effects of alcoholism are moderated by the quantity of lifetime alcohol consumption...

BACKGROUND: The increased susceptibility for developing alcohol dependence seen in offspring from families with alcohol dependence may be related to structural and functional differences in brain circuits that influence emotional processing. Early childhood environment, genetic variation in the serotonin transporter-linked polymorphic region (5-HTTLPR) of the SLCA4 gene and allelic variation in the Brain Derived Neurotrophic Factor (BDNF) gene have each been reported to be related to volumetric differences in the temporal lobe especially the amygdala...

As the number of women who use alcohol increases, so does the number of women who engage in alcohol abuse and develop alcohol dependence. The recent increased focus on women and gender differences in alcoholism research has largely come about following recognition that the face of alcoholism is changing, with alcoholism rates among men remaining stable and rising among women, particularly in younger women. As such, the need to understand gender differences in both acute and long-term effects of alcohol abuse has never been more critical...

PURPOSE: It is challenging to identify older adolescents at risk for alcohol dependence. This study investigated first-year college students who scored as dependent alcohol users (DAU), and examined their alcohol use and Facebook displays. MATERIALS AND METHODS: This longitudinal study recruited college students at two universities to complete a phone interview prior to college (Time 1) and one year later (Time 2). Interviews assessed lifetime and current alcohol use, and attitude (scale of 0=very negative to 6=very positive) and intention (scale of 0=not at all likely to 5=very likely) toward alcohol use...
