Incarcerated Young Men, Masculinity, and Trauma.

The current article is part of a unique comparative study of the experiences and adjustment of 190 incarcerated young men in both Scotland and Canada. In collecting data on the participants' lives, the authors learned of the multiple traumas and losses many of them had suffered. Many participants however seemed to adhere to a prison masculinity that may constrain help-seeking behavior. Ultimately, this article analyses the levels of trauma that exists in a population of incarcerated young men within the context and alongside of the masculine ideals they appeared to adhere to. This article advocates for gender-responsive trauma-informed care for incarcerated young men that incorporates an exploration and understanding of masculine identity and how it interacts with help-seeking and trauma recovery.

The prevalence of childhood bereavement in Scotland and its relationship with disadvantage: the significance of a public health approach to death, dying and bereavement.

BACKGROUND AND METHOD: There is an absence of research on the prevalence of bereavement during early childhood and the relationship between childhood bereavement and socioeconomic status (SES) and this poses a challenge in both understanding and supporting children's bereavement experiences. Using longitudinal data from the Growing Up in Scotland study, which tracks the lives of three nationally representative cohorts of children, this paper aimed to address these gaps in research. It specifically drew on data from Birth Cohort 1 to document the recorded bereavements of 2,815 children who completed all 8 sweeps of data collection, from age 10 months to 10 years. FINDINGS: The study found that 50.8% of all children are bereaved of a parent, sibling, grandparent or other close family member by age 8 and this rises to 62% by age 10. The most common death experienced was that of a grandparent or other close relative. The study also found that children born into the lowest income households are at greater risk of being bereaved of a parent or sibling than those born into the highest income households. DISCUSSION AND CONCLUSION: Given the prevalence of childhood bereavement and its relationship with disadvantage, this paper argues that there is an important need to understand bereavement as a universal issue that is affected by the social conditions in which a child becomes bereaved, as well as an individual experience potentially requiring specialist support. This paper thus seeks to position childhood bereavement more firmly within the public health approach to palliative and bereavement care discourse and contends that doing so provides a unique and comprehensive opportunity to better understand and holistically respond to the experience of bereavement during childhood.

Blockade of the 5-HT transporter contributes to the behavioural, neuronal and molecular effects of cocaine.

BACKGROUND AND PURPOSE: The psychostimulant cocaine induces complex molecular, cellular and behavioural responses as a consequence of inhibiting presynaptic dopamine, noradrenaline and 5-HT transporters. To elucidate 5-HT transporter (SERT)-specific contributions to cocaine action, we evaluated cocaine effects in the SERT Met172 knock-in mouse, which expresses a SERT coding substitution that eliminates high-affinity cocaine recognition. EXPERIMENTAL APPROACH: We measured the effects of SERT Met172 on cocaine antagonism of 5-HT re-uptake using ex vivo synaptosome preparations and in vivo microdialysis. We assessed SERT dependence of cocaine actions behaviourally through acute and chronic locomotor activation, sensitization, conditioned place preference (CPP) and oral cocaine consumption. We used c-Fos, quantitative RT-PCR and RNA sequencing methods for insights into cellular and molecular networks supporting SERT-dependent cocaine actions. KEY RESULTS: SERT Met172 mice demonstrated functional insensitivity for cocaine at SERT. Although they displayed wild-type levels of acute cocaine-induced hyperactivity or chronic sensitization, the pattern of acute motor activation was different, with a bias toward thigmotaxis. CPP was increased, and a time-dependent elevation in oral cocaine consumption was observed. SERT Met172 mice displayed relatively higher levels of neuronal activation in the hippocampus, piriform cortex and prelimbic cortex (PrL), accompanied by region-dependent changes in immediate early gene expression. Distinct SERT-dependent gene expression networks triggered by acute and chronic cocaine administration were identified, including PrL Akt and nucleus accumbens ERK1/2 signalling. CONCLUSION AND IMPLICATIONS: Our studies reveal distinct SERT contributions to cocaine action, reinforcing the possibility of targeting specific aspects of cocaine addiction by modulation of 5-HT signalling.
