Objective: To describe the prevalence and demographic, clinical and functional correlates of childhood trauma in patients attending early psychosis clinics. Method: Participants were recruited from outpatients attending four early psychosis services. Exposure to childhood trauma was assessed using the Childhood Trauma Questionnaire (CTQ). Psychopathology was measured using the Positive and Negative Syndrome Scale and the Depression, Anxiety and Stress Scale. Social and vocational functioning and substance use were also assessed. Results: Over three-quarters of the 100 patients reported exposure to any childhood trauma. Emotional, physical and sexual abuse were reported by 54%, 23% and 28% of patients, respectively, while 49% and 42% of patients reported emotional and physical neglect, respectively. Female participants were significantly more likely to be exposed to emotional and sexual abuse. Exposure to childhood trauma was correlated with positive psychotic symptoms and higher levels of depressive, anxiety and stress symptoms; however, it had no impact on social or vocational functioning or recent substance use. Conclusion: Exposure to childhood trauma was common in patients with early psychosis, and associated with increased symptomatology. Existing recommendations that standard clinical assessment of patients with early psychosis should include inquiry into exposure to childhood trauma are supported.

The purpose of this work is to use the concepts of human time and cultural trauma in a biographical study of the turning points in the recent history of Estonia. This research is primarily based on 148 in-depth biographical interviews conducted in Estonia and Sweden in 1995-2005, supplemented by excerpts from 5 collections and 10 individually published autobiographies. The main body of the thesis consists of six published and of two forthcoming separate refereed articles, summarised in the theoretical introduction, and Appendix of the full texts of three particular life stories. The topic of the first article is the generational composition and the collective action frames of anti-Soviet social mobilisation in Estonia in 1940-1990. The second article details the differentiation of the rites of passage and the calendar traditions as a strategy to adapt to the rapidly changed political realities, comparatively in Soviet Estonia and among the boat-refugees in Sweden. The third article investigates the life stories of the double-minded strategic generation of the Estonian-inclined Communists, who attempted to work within the Soviet system while professing to uphold the ideals of pre-war Estonia. The fourth article is concentrated on the problems of double mental standards as a coping strategy in a contradictory social reality. The fifth article implements the theory of cultural trauma for the social practice of singing nationalism in Estonia. The sixth article bridges the ideas of Russian theoreticians concerning cultural dialogue and the Western paradigm of cultural trauma, with examples from Estonian Russian life stories. The seventh article takes a biographical look at the logic of the unraveling of cultural trauma through four Soviet decades. The eighth article explores the re-shaping of citizen activities as a strategy of coping with the loss of the independent nation state, comparatively in Soviet Estonia and among Swedish Estonians. Cultural trauma is interpreted as the re-ordering of the society s value-normative constellation due to sharp, violent, usually political events. The first one under consideration was caused by the occupations of the Republic of Estonia by the Soviet army in 1940-45. After half a century of suppression the memories of these events resurfaced as different stories describing the long-term, often inter-generational strategies of coping with the value collapse. The second cultural trauma is revealed together with the collapse of the Soviet power and ideology in Estonia in 1991. According to empirical data, the following three trauma discourses have been reconstructed: - the forced adaptation to Soviet order of the homeland Estonians; - the difficulty of preserving Estonian identity in exile (Sweden); - the identity crisis of the Russian population of Estonia. Comparative analyses of these discourses have shown that opposing experiences and worldviews cause conflicting interpretations of the past. Different social and ethnic groups consider coping with cultural trauma as a matter of self-defence and create appropriate usable pasts to identify with. Keywords: human time, cultural trauma, frame analysis, discourse, life stories

[ES] Veintisiete años después de la publicación de la primera síntesis sobre el Paleolítico superior inicial en el País Vasco, nos proponemos actualizar esta temática de acuerdo a los avances desarrollados en la investigación de campo a lo largo de estos años. Valoramos como un hito el citado artículo debido a diferentes motivos, que se exponen con cierto detalle en el texto. Debido a diferentes circunstancias (que intentaremos exponer), se detecta un desfase creciente entre actividad de campo y publicación de resultados, que de no corregirse puede dar lugar a excavaciones inéditas y, por tanto, no productivas.

O presente trabalho investiga os diferentes processos sociais relacionados ao surgimento do transtorno de estresse pós-traumático (TEPT) no contexto brasileiro. Categoria diagnóstica norte-americana instituída na década de 1980 pela terceira edição do Manual Diagnóstico e Estatístico de Transtornos Mentais (Diagnostic and Statistical Manual of Mental Disorders DSM-III) uma publicação da Associação Americana de Psiquiatria (American Psychiatric Association APA) o TEPT tornou-se, desde a sua aparição, uma das categorias nosológicas mais difundidas, estudadas e diagnosticadas da psiquiatria contemporânea. A partir do cotidiano de um laboratório de pesquisa e tratamento do TEPT, de análises conversacionais dos atendimentos médicos, de um estudo das diferentes escalas psiquiátricas utilizadas no acompanhamento dos pacientes e de pesquisas sobre a mídia relacionada às experiências traumáticas buscou-se entender os entrelaçamentos entre os processos de difusão e a construção da legitimidade da categoria diagnóstica do TEPT. A abordagem aqui proposta pretende ir além do aparente dilema entre uma concepção medicalizada que assumem a existência o TEPT como um fenômeno natural e as abordagens sócio-antropológicas que veem o TEPT como uma experiência culturalmente construída. Por fim, pretendo mostrar, pela investigação dos alicerces políticos e culturais dos denominados transtornos mentais, que o estatuto social dos diagnósticos e dos tratamentos da moderna psiquiatria só pode ser compreendido tendo como referência as dinâmicas de longo prazo nas sociedades contemporâneas.

O transtorno de estresse pós-traumático (TEPT) é um transtorno de ansiedade que pode ser desenvolvido após a ocorrência de um evento traumático, e que costuma vir acompanhado de um significativo comprometimento da qualidade de vida. Indivíduos diagnosticados com o TEPT apresentam níveis de frequência cardíaca mais elevados em situações de exposição a eventos estressores, como sons e imagens que relembram a experiência traumática. No entanto, estudos que avaliaram a frequência cardíaca no momento do trauma como preditor do desenvolvimento de TEPT não apresentam resultados consistentes. Os objetivos deste trabalho foram: verificar se frequência cardíaca (FC) peritraumática de repouso, após exposição ao trauma, é um fator preditor para o desenvolvimento do TEPT e para a gravidade dos sintomas de TEPT em adultos. Foi realizada uma revisão sistemática, seguida de metanálise, utilizando-se as bases eletrônicas PUBMED, LILACS, PILOTS, PsycoINFO e Web of Science. Foram incluídos 17 estudos nesta revisão sistemática. Os resultados de dez estudos foram utilizados para a metanálise das diferenças de médias de FC combinada. Oito estudos foram utilizados para a metanálise das correlações entre a FC e a gravidade dos sintomas de TEPT. Modelos de meta-regressão foram ajustados para identificar variáveis que pudessem explicar a heterogeneidade entre os estudos. A FC peritraumática no grupo de pacientes com TEPT é, em média, 3,98 batimento por mimuto (bpm) (p=0,04) maior em comparação com aqueles sem o transtorno, e o coeficiente de correlação de Pearson combinado foi de 0,14 (p=0,05).Consistente com a hipótese levantada, a frequência cardíaca peritraumática de repouso foi maior em indivíduos que desenvolveram o TEPT. Contudo, mensuração mais próxima do evento traumático e a exclusão de casos dissociativos poderão ampliar a magnitude do efeito encontrado, tornando este biomarcador simples e facilmente obtido um preditor clinicamente útil do desenvolvimento de TEPT.

Trauma care in the general population has largely become protocol-driven, with an emphasis on fast and efficient treatment, good team communication at all levels of care including prehospital care, initial resuscitation, intensive care, and rehabilitation. Most available literature on trauma care has focused on adults, allowing the potential to apply concepts from adult care to pediatric care. But there remain issues that will always be specific to pediatric patients that may not translate from adults. Several new devices such as intraosseous (IO) needle systems and techniques such as ultrasonography to cannulate central and peripheral veins have become available for integration into our pre-existing trauma care system for children. This review will focus specifically on the latest techniques and evidence available for establishing intravenous access, rational approaches to fluid resuscitation, and blood product transfusion in the pediatric trauma patient.

Using longitudinal data, the present study examined change in midlife neuroticism following trauma exposure. Our primary analyses included 670 participants (M(age) = 60.55; 65.22% male, 99.70% Caucasian) who completed the NEO Personality Inventory at ages 42 and 50 and reported their lifetime exposure to traumatic events approximately 10 years later. No differences in pre- and post-trauma neuroticism scores were found among individuals who experienced all of their lifetime traumas in the interval between the personality assessments. Results were instead consistent with normative age-related declines in neuroticism throughout adulthood. Furthermore, longitudinal changes in neuroticism scores did not differ between individuals with and without histories of midlife trauma exposure. Examination of change in neuroticism following life-threatening traumas yielded a comparable pattern of results. Analysis of facet-level scores largely replicated findings from the domain scores. Overall, our findings suggest that neuroticism does not reliably change following exposure to traumatic events in middle adulthood. Supplemental analyses indicated that individuals exposed to life-threatening traumas in childhood or adolescence reported higher midlife neuroticism than individuals who experienced severe traumas in adulthood. Life-threatening traumatic events encountered early in life may have a more pronounced impact on adulthood personality than recent traumatic events.
