NERVENARZT. 2017;88(1):26-33.With each additional accumulative exposure to severe and traumatic stressors, the likelihood of developing mental health problems and physical diseases increases. Displaced individuals have usually experienced a number of serious threats to health due to organized violence in their home country or attacks during the flight. Frequently, domestic violence adds additional strain to the stressors experienced. The resulting impairments in psychosocial functioning reduce the resources needed for social adjustment and integration. Social exclusion then in turn often further aggravates the existing mental health complications. For the treatment of trauma spectrum disorders, different evidence-based psychotherapies are available. In high-income countries, trained and licensed psychotherapists are typically in positions to apply such interventions; however, even an advanced system with a high capacity, such as the psychotherapeutic care offered in Germany, severely struggles to manage the demands associated with the rapid addition of hundreds of thousands of displaced people. Germany's mental healthcare system at present lacks the resources, both human and technological, to effectively manage the present demands. Systematic scientific studies in resource-poor regions of war and conflict have demonstrated that the dissemination of effective treatment to local personnel, even with limited training, results in substantial improvements in the mental health challenges within the community: Organized as a cascade model, members of the refugee community learn to identify weakened fellow citizens requiring in-depth diagnostic interviews. Educated, bilingual individuals acquainted with their country's healthcare system (e. g. nurses, teachers and social workers) receive training to conduct structured interviews and evidence-based interventions under the supervision of centrally organized licensed psychotherapists. More complex cases are referred to local psychotherapists, psychiatrists or specialized treatment centers. These humanitarian efforts are based on the convention for the protection of human rights and secure the safety, freedom and dignity of these persons

Stigmatization Is Associated With Increased PTSD Risk After Traumatic Stress and Diminished Likelihood of Spontaneous Remission–A Study With East-African Conflict Survivors

Studies in conflict population have repeatedly documented that the number of traumatic event types experienced (trauma load) increases the risk to develop posttraumatic stress disorder (PTSD) in a dose-dependent manner. Misconceptions about survivors' experiences and actions during the war, as well as mental health symptoms frequently lead to stigmatization by their own families and the community, which might render them even more vulnerable for PTSD development and prevent successful recovery. We therefore investigated whether stigmatization affects trauma-related psychopathology beyond the well-known effect of trauma load. The study sample comprised N = 1131 survivors of the rebel war led by the Lord's Resistance Army (LRA) in Northern Uganda, including a large proportion of formerly abducted individuals and child soldiers. We investigated how the experience of stigmatization affects PTSD risk and the likelihood of spontaneous remission, taking trauma load into account. Further, the association of stigmatization with treatment outcome was determined in a subsample of N = 284 individuals with PTSD who received trauma-focused psychotherapy. More than one third of the total sample, and almost two-thirds of the therapy subsample, reported experiences of stigmatization. The main reasons for stigmatization were related to an association with a rebel group (e.g., being called a rebel), followed by mental health problems/PTSD symptoms and HIV/AIDS. Stigmatization was strongly associated with a higher prevalence of lifetime and current PTSD, a diminished probability of spontaneous remission and higher PTSD symptoms before and after trauma-focused psychotherapy, beyond the effect of trauma load. In sum, our results support the assumption that stigmatization aggravates trauma-related psychopathology and impede symptom improvement. In post-conflict regions, community and family interventions which aim at reducing stigmatization and discrimination might therefore complement individual psychotherapy in order to allow survivors to recover and reintegrate into society

The efficacy of Narrative Exposure Therapy for Children (KIDNET) as a treatment for traumatized young refugees versus treatment as usual: study protocol for a multi-center randomized controlled trial (YOURTREAT).

Wilker S, Catani C, Wittmann J, et al. The efficacy of Narrative Exposure Therapy for Children (KIDNET) as a treatment for traumatized young refugees versus treatment as usual: study protocol for a multi-center randomized controlled trial (YOURTREAT). Trials. 2020;21(1): 185.BACKGROUND: Germany hosts a large number of refugees from war-affected countries. The integration of refugees, in particular young refugees from the Middle East, is one of the major current social challenges in Germany. Mental disorders, first of all post-traumatic stress disorder (PTSD) that results from war experiences, are common among young refugees and interfere with quality of life as well as functional integration. Evidence regarding effective treatment options for this population is scarce. In this trial, we aim to evaluate the pragmatic, short-term psychotherapy Narrative Exposure Therapy for Children (KIDNET) for the treatment of young refugees in Germany.; METHODS: In a rater-blinded, multi-center, randomized-controlled trial, KIDNET is compared to treatment as usual (TAU) within the general health care system. A total number of 80 young refugees who fulfill the diagnostic criteria of PTSD will be randomized to either KIDNET or TAU. Diagnostic interviews will take place at baseline before treatment as well as 6 and 12months thereafter. They will assess exposure to traumatic events, PTSD and comorbid symptoms, as well as parameters of integration.; DISCUSSION: The results of this study should provide evidence regarding effective treatment options for young refugees in Germany, a population that has been understudied and received only limited access to mental health care so far. Next to the effects of treatment on mental health outcomes, integration parameters will be investigated. Therefore, this study should provide broad insights into treatment options for young refugees and their potential implications on successful integration.; TRIAL REGISTRATION: German Clinical Trials Register (Deutsches Register Klinischer Studien; DRKS), ID: DRKS00017222.

Evolutionary conserved role of neural cell adhesion molecule-1 in memory.

Vukojevic V, Mastrandreas P, Arnold A, et al. Evolutionary conserved role of neural cell adhesion molecule-1 in memory. Translational psychiatry. 2020;10(1): 217.The neural cell adhesion molecule 1 (NCAM-1) has been implicated in several brain-related biological processes, including neuronal migration, axonal branching, fasciculation, and synaptogenesis, with a pivotal role in synaptic plasticity. Here, we investigated the evolutionary conserved role of NCAM-1 in learning and memory. First, we investigated sustained changes in ncam-1 expression following aversive olfactory conditioning in C. elegans using molecular genetic methods. Furthermore, we examined the link between epigenetic signatures of the NCAM1 gene and memory in two human samples of healthy individuals (N=568 and N=319) and in two samples of traumatized individuals (N=350 and N=463). We found that olfactory conditioning in C. elegans induced ncam-1 expression and that loss of ncam-1 function selectively impaired associative long-term memory, without causing acquisition, sensory, or short-term memory deficits. Reintroduction of the C. elegans or human NCAM1 fully rescued memory impairment, suggesting a conserved role of NCAM1 for memory. In parallel, DNA methylation of the NCAM1 promoter in two independent healthy Swiss cohorts was associated with memory performance. In two independent Sub-Saharan populations of conflict zone survivors who had faced severe trauma, DNA methylation at an alternative promoter of the NCAM1 gene was associated with traumatic memories. Our results support a role of NCAM1 in associative memory in nematodes and humans, and might, ultimately, be helpful in elucidating diagnostic markers or suggest novel therapy targets for memory-related disorders, like PTSD

Response to responsible research assessment I and II from the perspective of the DGPs working group on open science in clinical psychology

We comment on the papers by Schönbrodt et al. (2022) and Gärtner et al. (2022) on responsible research assessment from the perspective of clinical psychology and psychotherapy research. Schönbrodt et al. (2022) propose four principles to guide hiring and promotion in psychology: (1) In addition to publications in scientific journals, data sets and the development of research software should be considered. (2) Quantitative metrics can be useful, but they should be valid and applied responsibly. (3) Methodological rigor, research impact, and work quantity should be considered as three separate dimensions for evaluating research contributions. (4) The quality of work should be prioritized over the number of citations or the quantity of research output. From the perspective of clinical psychology, we endorse the initiative to update current practice by establishing a matrix for comprehensive, transparent and fair evaluation criteria. In the following, we will both comment on and complement these criteria from a clinical-psychological perspective

Selection of antigenically advanced variants of seasonal influenza viruses.

Influenza viruses mutate frequently, necessitating constant updates of vaccine viruses. To establish experimental approaches that may complement the current vaccine strain selection process, we selected antigenic variants from human H1N1 and H3N2 influenza virus libraries possessing random mutations in the globular head of the haemagglutinin protein (which includes the antigenic sites) by incubating them with human and/or ferret convalescent sera to human H1N1 and H3N2 viruses. We also selected antigenic escape variants from human viruses treated with convalescent sera and from mice that had been previously immunized against human influenza viruses. Our pilot studies with past influenza viruses identified escape mutants that were antigenically similar to variants that emerged in nature, establishing the feasibility of our approach. Our studies with contemporary human influenza viruses identified escape mutants before they caused an epidemic in 2014-2015. This approach may aid in the prediction of potential antigenic escape variants and the selection of future vaccine candidates before they become widespread in nature.This work was supported by the Bill & Melinda Gates Foundation Global Health Grant OPPGH5383; National Institute of Allergy and Infectious Diseases (NIAID) Public Health Service research grants (USA); ERATO (Japan Science and Technology Agency); the Center for Research on Influenza Pathogenesis (CRIP) funded by the NIAID Contracts HHSN266200700010C and HHSN27 2201400008C; the Japan Initiative for Global Research Network on Infectious Diseases; Grants-in-Aid for Specially Promoted Research from the Ministry of Education, Culture, Sports, Science, and Technology, Japan; Grants-in-Aid from the Ministry of Health, Labour and Welfare, Japan; grants from the Strategic Basic Research Program of the Japan Science and Technology Agency; and by the Advanced Research & Development Programs for Medical Innovation from the Japan Agency for Medical Research and Development (AMED).
