Childhood sexual abuse in boys and men: The case for gender-sensitive interventions.

OBJECTIVE: To review the literature on the experiences of boys and men exposed to childhood sexual abuse, and to assess the implications of this literature for trials of interventions and tailored services for this population. METHOD: We conducted a narrative review of papers pertaining to boys and men exposed to childhood sexual abuse. Implications of this literature for treatment were critically appraised. RESULTS: Boys and men suffer the negative sequelae of childhood sexual abuse to the same (and sometimes greater) extent as girls and women. Boys and men also experience a number of unique challenges, as the abuse experience may undermine masculine identities and relations. This conflict may contribute to the underreporting of childhood sexual abuse among boys and men. Boys and men are less likely to disclose their abuse experience and wait longer to disclose compared to girls and women. Existing estimates therefore likely underestimate the prevalence of childhood sexual abuse among boys and men. Additionally, to date, intervention trials for individuals exposed to childhood sexual abuse have included a disproportionately low number of boys and men, even based on existing prevalence estimates. CONCLUSIONS: Further investigation into the treatment needs of boys and men exposed to childhood sexual abuse is critically important. To facilitate a better understanding of their needs, intervention studies for this cohort should include a greater proportion of boys and men. Studies should also assess the influence of boys' and men's alignments to masculine norms for moderating treatment outcomes as a means to guide gender-sensitive treatments.

Subjective distress, self-harm, and suicidal ideation or behavior throughout trauma-focused cognitive-behavioral therapy in transitional age youth.

OBJECTIVE: Elevations in distress, self-harm, and suicidal ideation or behavior are of significant concern in clinical practice. We examined these in a pilot trial of Trauma Focused-Cognitive Behavioral Therapy (TF-CBT) for transitional age youth (aged 15-25 years) with histories of interpersonal trauma and symptoms of posttraumatic stress disorder. METHOD: Participants were 20 young people (13 females, M = 19.5 years) from a pilot study of TF-CBT. Frequencies of elevated distress, self-harm, and suicidal ideation or behavior were measured throughout treatment sessions and across the treatment phases of TF-CBT. RESULTS: Across the 279 sessions of TF-CBT (m = 15.5 sessions), there were 16 incidents of elevated distress in seven participants (i.e., six in Phase I and five each in Phases II and III); 15 incidents of self-harming behavior in seven participants (five incidents in each of the three phases) and one incident of both elevated distress and suicide ideation (Phase I). CONCLUSION: Findings indicate that there may be a relationship between the experience of in session distress and self-harming behaviors. The importance of safety planning and coping skills (acquired in Phase 1) is stressed to ensure the effective implementation of TF-CBT. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Relative efficacy of psychological interventions following interpersonal trauma on anxiety, depression, substance use, and PTSD symptoms in young people: A meta-analysis.

AIM: Interpersonal trauma exposures are associated with anxiety, depression, and substance use in youth populations (aged 12-25 years). This meta-analysis reports on the efficacy of psychological interventions on these symptom domains in addition to post-traumatic stress. METHODS: Following PRISMA guidelines, a search of electronic databases was performed for randomized controlled trials (RCTs) assessing interventions for young people following interpersonal trauma exposure. Risk of bias was assessed using the Cochrane Risk of Bias tool. Data were analysed using random-effects meta-analyses. RESULTS: Of the 4832 records screened, 78 studies were reviewed, and 10 RCTs, involving 679 participants (mean age 15.6 years), were analysed. There was a large pooled effect size for post-traumatic stress (7 studies, g = 1.43, 95% CI [0.37, 2.15], p = .002) and substance use (2 studies, g = 0.70, 95% CI [-0.11, 1.22], p < .001) and small effect sizes for anxiety (4 studies, g = 0.30, 95% CI [0.10, 0.49], p = .003), and trend-level effect for depression (10 studies, g = 0.27, 95% CI [0.00, 0.54], p = .052). Heterogeneity was significant for post-traumatic stress and moderate for depression. CONCLUSIONS: High-quality RCTs of psychological interventions for anxiety, depression, substance use, and post-traumatic stress symptoms in young people exposed to interpersonal trauma are scarce. While available studies show either statistically significant or trend-level efficacy for psychological interventions in reducing these symptoms, wide confidence intervals, heterogeneity and small sample size mean that results need to be interpreted with caution.

Trauma-focused cognitive-behavioral therapy (TF-CBT) for interpersonal trauma in transitional-aged youth.

OBJECTIVE: Posttraumatic stress disorder (PTSD) following interpersonal trauma in transitional-aged youth (TAY), aged 15 to 25, is highly prevalent; however, evidence-based interventions have rarely been studied. METHOD: A single-group pre-/posttest study was conducted at headspace Sunshine, Melbourne, Australia, evaluating the feasibility, acceptability, safety, tolerability, and potential clinical effectiveness of trauma-focused cognitive-behavioral therapy (TF-CBT). RESULTS: An intent-to-treat analysis was conducted for N = 20 participants (65% female, n = 13) who attended a mean of 15 TF-CBT sessions over 25 weeks. At the end of treatment, only 1 of the 16 participants with a baseline PTSD diagnosis still met diagnostic criteria. Significant improvements were also noted for self-report measures of PTSD (d = -.83), anxiety (d = -.74), and depression (d = -.76). A minority of participants reported a brief exacerbation in symptoms of PTSD (n = 8) and anxiety and depression (n = 5) during stabilization and directly before and/or after the trauma-narration phase. However, all symptoms resolved at the end of treatment. The majority of participants (85%, n = 17) rated the intervention as helpful. CONCLUSION: Regardless of the expected temporary symptom exacerbation, the results indicated that TF-CBT was safe, tolerable, and acceptable. Transitional-aged youth is an emerging area of research. With limited research available on this age group to inform evidence-based practice, it is recommended that a randomized controlled trial is conducted to determine if TF-CBT (Cohen et al., 2017) can be effectively translated to this underresearched age group.

A Systematic Review and Synthesis of Trauma-Informed Care Within Outpatient and Counseling Health Settings for Young People.

There is growing consensus that outpatient health services for young people (aged 12-25 years) need to deliver trauma-informed care to ameliorate the effects of trauma, offer safe treatments, and avoid retraumatization. Trauma-informed care has become a familiar term for many professionals; however, its operating definition lacks clarity. MEDLINE, Embase, and PsycINFO were systematically searched to clarify what trauma-informed care is, and what it should achieve in these settings. We reviewed 3,381 unique records, of which 13 met criteria for inclusion. Content analysis identified 10 components of trauma-informed care as it has been operationalized in practice: seven of these occurred at the system-level (interagency collaboration; service provider training; safety; leadership, governance and agency processes; youth and family/carer choice in care; cultural and gender sensitivity; youth and family/carer participation), and three involved trauma-specific clinical practices (screening and assessment; psychoeducation; therapeutic interventions). There is a need for greater consensus regarding an operating definition of trauma-informed care and further research into outcomes for young people and their families/carers.

"Like a huge weight lifted off my shoulders": Exploring young peoples' experiences of treatment in a pilot trial of trauma-focused cognitive behavioral therapy.

Background: The efficacy of trauma-focused cognitive behavioral therapy (TF-CBT) is well-established, yet little work has been done to understand how young people experience this intervention.Method: Semi-structured interviews were conducted with 13 young people aged 17-25 years (M = 20.0, SD = 2.61) who received TF-CBT as part of a pilot trial. Transcripts were analyzed via interpretative phenomenological analysis.Results: Four super-ordinate themes were identified: (i) experience of authentic care, (ii) personal role in therapy and recovery, (iii) talking about trauma is difficult but important, and (iv), transformative change. Young people described authenticity on behalf of the therapist, which seemed to foster emotional connection and comfort discussing trauma. They emphasized the importance of retaining autonomy and control during therapy, and a degree of personal responsibility in their recovery. Talking about trauma was described as difficult and potentially distressing, but also as critical for recovery. Transformative life changes were noted, which had a significant impact on young peoples' future outlook and self-perception.Conclusions: This study suggests that therapists should be attuned to the interpersonal needs of clients, attempt to foster self-determination throughout therapy, and simultaneously recognize the difficulty and importance of trauma work for young people when delivering TF-CBT.

Local ATP generation by brain-type creatine kinase (CK-B) facilitates cell motility.

BACKGROUND: Creatine Kinases (CK) catalyze the reversible transfer of high-energy phosphate groups between ATP and phosphocreatine, thereby playing a storage and distribution role in cellular energetics. Brain-type CK (CK-B) deficiency is coupled to loss of function in neural cell circuits, altered bone-remodeling by osteoclasts and complement-mediated phagocytotic activity of macrophages, processes sharing dependency on actomyosin dynamics. METHODOLOGY/PRINCIPAL FINDINGS: Here, we provide evidence for direct coupling between CK-B and actomyosin activities in cortical microdomains of astrocytes and fibroblasts during spreading and migration. CK-B transiently accumulates in membrane ruffles and ablation of CK-B activity affects spreading and migration performance. Complementation experiments in CK-B-deficient fibroblasts, using new strategies to force protein relocalization from cytosol to cortical sites at membranes, confirmed the contribution of compartmentalized CK-B to cell morphogenetic dynamics. CONCLUSION/SIGNIFICANCE: Our results provide evidence that local cytoskeletal dynamics during cell motility is coupled to on-site availability of ATP generated by CK-B.

Modulation of cell motility by spatial repositioning of enzymatic ATP/ADP exchange capacity.

ATP is the "principal energy currency" in metabolism and the most versatile small molecular regulator of cellular activities. Although already much is known about the role of ATP in fundamental processes of living systems, data about its compartmentalization are rather scarce, and we still have only very limited understanding of whether patterns in the distribution of intracellular ATP concentration ("ATP inhomogeneity") do exist and have a regulatory role. Here we report on the analysis of coupling of local ATP supply to regulation of actomyosin behavior, a widespread and dynamic process with conspicuous high ATP dependence, which is central to cell shape changes and cell motility. As an experimental model, we use embryonic fibroblasts from knock-out mice without major ATP-ADP exchange enzymes, in which we (re)introduce the ATP/ADP exchange enzyme adenylate kinase-1 (AK1) and deliberately manipulate its spatial positioning by coupling to different artificial location tags. By transfection-complementation of AK1 variants and comparison with yellow fluorescent protein controls, we found that motility and spreading were enhanced in cells with AK1 with a focal contact guidance tag. Intermediary enhancement was observed in cells with membrane-targeted or cytosolic AK1. Use of a heterodimer-inducing approach for transient translocation of AK1 to focal contacts under conditions of constant global AK1 activity in the cell corroborated these results. Based on our findings with these model systems, we propose that local ATP supply in the cell periphery and "on site" fuelling of the actomyosin machinery, when maintained via enzymes involved in phosphoryl transfer, are codetermining factors in the control of cell motility.

Mild impairment of motor nerve repair in mice lacking PTP-BL tyrosine phosphatase activity.

Mouse PTP-BL is a large, nontransmembrane protein tyrosine phosphatase of unclear physiological function that consists of a KIND domain, a FERM domain, five PDZ domains, and a COOH-terminal catalytic PTP domain. PTP-BL and its human ortholog PTP-BAS have been proposed to play a role in the regulation of microfilament dynamics, cytokinesis, apoptosis, and neurite outgrowth. To investigate the biological function of PTP-BL enzyme activity, we have generated mice that lack the PTP-BL PTP moiety. These PTP-BL(DeltaP/DeltaP) mice are viable and fertile and do not present overt morphological alterations. Although PTP-BL is expressed in most hematopoietic cell lineages, no alterations of thymocyte development in PTP-BL(DeltaP/DeltaP) mice could be detected. Sciatic nerve lesioning revealed that sensory nerve recovery is unaltered in these mice. In contrast, a very mild but significant impairment of motor nerve repair was observed. Our findings exclude an essential role for PTP-BL as a phosphotyrosine phosphatase and rather are in line with a role as scaffolding or anchoring molecule.

The DMWD protein from the myotonic dystrophy (DM1) gene region is developmentally regulated and is present most prominently in synapse-dense brain areas.

The DMWD gene is located in the myotonic dystrophy (DM1) gene cluster on 19q, just upstream of the DMPK gene. RNA and protein products of this gene are ubiquitously expressed in all adult tissues, but occur most abundant in testes and brain. Altered expression of DMWD mRNA in DM1 patients has been observed, suggesting a role of the DMWD gene products in disease manifestation. Here we focussed on DMWD expression in mouse brain and followed mRNA and protein levels and (intra)cellular location in developing brain in vivo as well as in differentiating neuronal cell cultures in vitro. In the interval between postnatal days P7 and P21, the steady-state level of DMWD mRNA remained constant, whereas the DMWD protein (doublet of 70 kDa) level gradually increased during the same period. The DMWD protein was expressed throughout the brain, at a low level in glial cells, more prominently in neurons and specifically in the neuropil of brain areas with a high density of synaptic connections. Intracellularly, DMWD was dispersed in a punctuate fashion throughout the neural cell body, the nucleus and the dendrites with their synapses, but was excluded from axons. Based on these findings and on new literature data concerning the role of DMWD homologs in lower eukaryotes, we discuss the possible role of DMWD in the brain-related symptoms seen in DM1 patients.
