Council-based approaches to reforming the health care response to domestic violence: promising findings and cautionary tales.

Councils are commonly formed to address social issues including intimate partner violence (IPV). Research suggests that councils may be well positioned to achieve proximal outcomes, but that their success may depend on contextual factors. The current study compared providers and health care settings at two points in time to explore the degree to which the Health Care Council achieved proximal outcomes in the health care response to IPV, including: (a) providers' reported capacity to screen for IPV, (b) providers' beliefs about IPV as a health care issue and about the IPV screening process, (c) providers' screening behaviors and (d) organizational policies and protocols to encourage screening. This study, while preliminary, provides support for council-based efforts to stimulate change in the health care response to IPV and also highlights the central role that organizational environment plays in shaping desired outcomes.

"Changing the text": modeling council capacity to produce institutionalized change.

Collaboration is a ubiquitous approach to change, but is notoriously difficult and not definitively linked to desirable outcomes. Not surprisingly, the collaboration literature is replete with numerous facilitators and barriers to collaborative efforts. The current study aimed to develop a parsimonious model of factors influencing the success of collaborative efforts both internal and external to the council, including, (a) features of the council environment, (b) intermediate outcomes including the empowerment of members in the council context and the degree to which councils have generated social capital and (c) the extent to which collaborative efforts are occurring in a community context supportive of their aims. In particular, this study examines whether these factors affect the extent to which councils are positioned to achieve institutionalized change, or changes "in the text" that govern front line providers' (e.g., police, advocates) practices in the community response to intimate partner violence. Results suggest that perceived member empowerment, generation of social capital, and supportive community context are the most important predictors of the extent to which councils foster shifts in institutionalized change. Features of the council environment are only indirectly related to the degree to which institutionalized change is ultimately fostered as mediated by the generation of social capital. This suggests that the ability of members to act as change agents and the extent to which those in power support council efforts figure more prominently to facilitate or constrain council efforts than council functioning itself.

Elevation of 11ß-hydroxysteroid dehydrogenase type 2 activity in Holocaust survivor offspring: evidence for an intergenerational effect of maternal trauma exposure.

BACKGROUND: Adult offspring of Holocaust survivors comprise an informative cohort in which to study intergenerational transmission of the effects of trauma exposure. Lower cortisol and enhanced glucocorticoid sensitivity have been previously demonstrated in Holocaust survivors with PTSD, and in offspring of Holocaust survivors in association with maternal PTSD. In other work, reduction in the activity of the enzyme 11ß-hydroxysteroid dehydrogenase type 2 (11ß-HSD-2), which inactivates cortisol, was identified in Holocaust survivors in comparison to age-matched, unexposed Jewish controls. Therefore, we investigated glucocorticoid metabolism in offspring of Holocaust survivors to evaluate if similar enzymatic decrements would be observed that might help to explain glucocorticoid alterations previously shown for Holocaust offspring. METHODS: Holocaust offspring (n=85) and comparison subjects (n=27) were evaluated with clinical diagnostic interview and self-rating scales, and asked to collect a 24-h urine sample from which concentrations of cortisol and glucocorticoid metabolites were assayed by GCMS. 11ß-HSD-2 activity was determined as the ratio of urinary cortisone to cortisol. RESULTS: Significantly reduced cortisol excretion was observed in Holocaust offspring compared to controls (p=.046), as had been shown for Holocaust survivors. However, 11ß-HSD-2 activity was elevated for offspring compared to controls (p=.008), particularly among those whose mothers had been children, rather than adolescents or adults, during World War II (p=.032). The effect of paternal Holocaust exposure could not be reliably investigated in the current sample. CONCLUSIONS: The inverse association of offspring 11ß-HSD-2 activity with maternal age at Holocaust exposure is consistent with the influence of glucocorticoid programming. Whereas a long standing reduction in 11ß-HSD-2 activity among survivors is readily interpreted in the context of Holocaust related deprivation, understanding the directional effect on offspring will require replication and further exploration.

Epigenetic Biomarkers as Predictors and Correlates of Symptom Improvement Following Psychotherapy in Combat Veterans with PTSD.

Epigenetic alterations offer promise as diagnostic or prognostic markers, but it is not known whether these measures associate with, or predict, clinical state. These questions were addressed in a pilot study with combat veterans with PTSD to determine whether cytosine methylation in promoter regions of the glucocorticoid related NR3C1 and FKBP51 genes would predict or associate with treatment outcome. Veterans with PTSD received prolonged exposure (PE) psychotherapy, yielding responders (n = 8), defined by no longer meeting diagnostic criteria for PTSD, and non-responders (n = 8). Blood samples were obtained at pre-treatment, after 12 weeks of psychotherapy (post-treatment), and after a 3-month follow-up. Methylation was examined in DNA extracted from lymphocytes. Measures reflecting glucocorticoid receptor (GR) activity were also obtained (i.e., plasma and 24 h-urinary cortisol, plasma ACTH, lymphocyte lysozyme IC50-DEX, and plasma neuropeptide-Y). Methylation of the GR gene (NR3C1) exon 1F promoter assessed at pre-treatment predicted treatment outcome, but was not significantly altered in responders or non-responders at post-treatment or follow-up. In contrast, methylation of the FKBP5 gene (FKBP51) exon 1 promoter region did not predict treatment response, but decreased in association with recovery. In a subset, a corresponding group difference in FKBP5 gene expression was observed, with responders showing higher gene expression at post-treatment than non-responders. Endocrine markers were also associated with the epigenetic markers. These preliminary observations require replication and validation. However, the results support research indicating that some glucocorticoid related genes are subject to environmental regulation throughout life. Moreover, psychotherapy constitutes a form of "environmental regulation" that may alter epigenetic state. Finally, the results further suggest that different genes may be associated with prognosis and symptom state, respectively.
