A Rat Model of the Brain-Derived Neurotrophic Factor Val66Met Polymorphism Shows Attenuated Motivation for Alcohol Self-Administration and Diminished Propensity for Cue-Induced Relapse in Females.

Brain-derived neurotrophic factor (BDNF) has been implicated in alcohol use disorder. The Val66Met polymorphism is a common variant of the BDNF gene (rs6265) which reduces activity-dependent BDNF release, and has been suggested as a risk factor for psychiatric disorders and substance use. Using an operant self-administration paradigm, this study aimed to investigate ethanol preference and ethanol seeking in a novel rat model of the BDNF Val66Met polymorphism, Val68Met rats. Male and female BDNF Val68Met rats of three genotypes (Val/Val, Val/Met and Met/Met) were trained to lever press for a 10% ethanol solution. There was no effect of Val68Met genotype on acquisition of stable response to ethanol or its extinction. Met/Met rats of both sexes had a slight, but significantly lower breakpoint during progressive ratio sessions while female rats with the Met/Met genotype demonstrated a lower propensity for reinstatement of responding to cues. There were no effects of Val68Met genotype on anxiety-like behaviour or locomotor activity. In conclusion, Met/Met rats showed lower motivation to continue to press for a reward, and also a decreased propensity to relapse, suggesting a possible protective effect of the Met/Met genotype against alcohol use disorder, at least in females.

Creating community: Expanding access to psychosocial programs for Latina breast cancer survivors.

OBJECTIVE: Breast cancer survivors often derive benefits from psychosocial interventions, but less is known about Latina women's experiences. Given the disproportionately high disease burden faced by Latina survivors, it is critical to examine ways to enhance access for this population. Thus, the present study aimed to (a) examine women's perceptions of factors associated with effective delivery of a psychosocial program designed for Spanish speaking women with limited access to care, and (b) identify the mechanisms by which the program enhanced women's psychological well-being. METHODS: In a qualitative study, in-depth interviews were conducted with 15 immigrant Latina breast cancer survivors who previously received psychosocial services at a community-based organization. Grounded theory was used to analyze the data. RESULTS: Through open, axial, and selective coding, we arrived at the core category achieving a sense of community. The psychosocial program promoted access and enhanced women's psychological well-being by creating a sense of community among participants. This was facilitated by three primary aspects of service provision: access factors, a holistic approach to health, and therapeutic factors imparted through a biweekly support group. CONCLUSIONS: Psychosocial services promoted a sense of community among Latina breast cancer survivors while reflecting their cultural values and unique psychosocial needs. Findings may guide the development of interventions to increase access to care, enhance health outcomes, and create and maintain a sense of community among medically underserved populations.

Using social network analysis as a tool in action research.

The following paper presents case examples of one research team's use of social network analysis (SNA) with three different collaboratives in South Florida: (a) a Collective Impact initiative seeking to end youth homelessness, (b) a university collaborative of campus organizations working towards Black students' concerns, and (c) a movement network of local social justice organizations. The research team used SNA to assess the level of connectivity of three different community coalitions. While research questions were slightly different for each collaborative, each project asked about the frequency of communication between organizations to determine connectivity. Results vary between case examples. Both the Youth Homeless Collaboration and the Black Student Association used Gephi to analyze results, while The Community Partnership used R to measure network centrality. The paper concludes with a general discussion of challenges related to using SNA as an action research tool, as well as the role of power in organizational networks.

Effects of Intensive Family Preservation Services in Rural Tennessee on Parental Hopefulness with Families Affected by Substance Use.

This article describes how Building Strong Families in Rural Tennessee (BS-FinRT) increased hopefulness and helped to promote the policy goal of developing a recovery focus among families with vulnerabilities. These outcomes were achieved by implementing collaborative strategies for addressing issues of child safety, substance use, and family stability. Early analyses of the program's outcomes indicated an unexpected positive influence on parent and child hopefulness. Further analyses found that changes in hope between baseline and discharge correlated positively with changes over the same time period in problem severity, general functioning, and mental health symptomology.
