ABSTRACT

BACKGROUND: The aim of this article is to summarize the current state of research on the effectiveness of psychotherapeutic treatment of posttraumatic stress disorder (PTSD). METHODS: The results of current meta-analyses and trend-setting individual studies are summarized and the most important forms of intervention are explained. RESULTS: The psychotherapeutic treatment methods for PTSD are very effective, the effect sizes are large and superior to those of pharmacotherapy. Trauma exposure and cognitive restructuring are most effective. Trauma-focused procedures are generally superior to other forms of psychotherapy. A range of different cognitive behavioral procedures as well as eye movement desensitization and reprocessing are recommended. The most recent initial findings confirm a very good effectiveness for imagery rescripting methods as protective interventions without a formal confrontation with trauma. Individual therapy works better than group psychotherapy. In the group setting cognitive processing therapy has proven to be the best intervention. Trauma-focused treatment should also be used when comorbid conditions such as schizophrenia, bipolar disorder or addiction are present. DISCUSSION: Trauma-focused psychotherapy in an individual setting is the treatment of choice for PTSD. A large selection of effective methods and well-reviewed manuals are available. The German language S3 guidelines are currently being updated.

ABSTRACT

Introduction: Cultural factors were shown to be particularly relevant for the development and expression of posttraumatic stress. Recently, the concept of cultural scripts of trauma has been introduced, which proposes that trauma sequelae elements may be sequentially linked and specifically associated with cultural factors. Furthermore, a cascade model is proposed, including trauma exposure, demographic characteristics, cultural affiliation, and trauma-related value orientations as influencing factors of posttraumatic development. The purpose of this Network Project is to investigate cultural psychological factors that contribute to the expression of posttraumatic stress.Methods: The present Network Project implements a mixed methods approach and will be conducted in 5 different study sites, including Switzerland, Israel, Georgia, China, and East Africa. In sub-study I, the cultural scripts of traumatic stress inventories (CSTIs) will be developed. These scales provide a pool of trauma sequelae elements for each cultural group. For this purpose, focus groups with trauma survivors and trauma experts will be conducted and analysed using qualitative research methods. Sub-study II implements a validation analysis of the CSTIs and the empirical investigation of a cultural cascade model. This quantitative approach will include a larger sample of individuals who experienced traumatic life events.Discussion: This contribution is timely and enriches the knowledge of trauma and culture. Future publications of this Network Project will address trauma sequelae from a cultural perspective and provide diagnostic and psychotherapeutic implications.


This paper presents a Network Project that investigates cultural factors in posttraumatic sequelae.The Network Project encompasses an innovative research design with both qualitative and quantitative methods.New developments in the field of cultural clinical psychology are introduced, including cultural scripts of trauma and a cascade model of cultural factors in posttraumatic symptom expression.

ABSTRACT

BACKGROUND: The concept of cultural scripts has proven to be very useful for describing depression-like psychological complaints in different cultural regions of the world. The article presents the galaxy model and its implementation in the model of cultural scripts theoretically for the first time and connects these with cultural psychological value research. A new, extensive series of research projects aims to investigate post-trauma -related psychological complaints in various regions of the world. METHODS: The work in two countries/regions began with focus groups in which elements of cultural scripts were collected by traumatized clients and/or by (therapeutic) experts. For this purpose, a theory-based framework of possible post-traumatic script elements was provided. In Switzerland, focus groups were conducted with patients and experts. Focus groups were conducted with genocide survivors and other trauma victims in Rwanda and three East African countries. The evaluation was semi-quantitative. RESULTS: In Switzerland, around 50 symptoms and changes were mentioned as script elements (e. g. still having to function). Approximately 100 symptoms and changes were mentioned as script elements in East Africa (e. g. loss of dignity). The first temporal connections (i. e. strong scripts) were found for the Swiss scripts (e. g. self-devaluation - urge to function). In the East African study, cultural value orientations underlying the script groupings were also assessed (e. g. community reputation). DISCUSSION: The illustrative results presented here demonstrate the galaxy model and the suitability of the cultural script concept for recording the effects of trauma. There are differences and similarities in the two world regions examined so far. Further steps at the two study sites will be the temporal connections and the relationships to value orientations. The studies will be started at the other study sites in the following years.

ABSTRACT

BACKGROUND: The novel concept of cultural scripts of trauma sequelae captures culture-specific expressions of posttraumatic distress (e.g., cognitive, emotional, interpersonal, psychosomatic changes) and their temporal associations. Cultural scripts of trauma sequelae complement pan-cultural (etic) diagnoses, such as posttraumatic stress disorder (PTSD) and Complex PTSD, as well as the cultural syndromes concept. OBJECTIVE: This study aimed to develop the cultural scripts of trauma inventory (CSTI) for German-speaking Switzerland and to explore temporal associations of script elements. METHOD: Five semi-structured focus groups were conducted with psychotraumatologists (n = 8) and Swiss trauma survivors (n = 7). The interview schedule included open questions about different domains of potential posttraumatic changes (emotions, cognitions, worldviews, interpersonal relationships, body-related experiences, behavior, and growth). Data were analyzed using qualitative content analysis. RESULTS: The Swiss CSTI includes 57 emic elements that represent salient trauma sequelae (30 conformed with a theoretically derived item pool, 27 were newly phrased). Temporal script associations were visualized in a network, whereby self-deprecation, the urge to function and overcompensate, and the urge to hide and endure suffering had the highest number of connections. CONCLUSION: While many posttraumatic changes identified in the present work seem to mirror pan-cultural phenomena represented in the Complex PTSD concept (e.g., self-deprecation), others (e.g., urge to function and perform, urge to hide and endure suffering) may be prominently related to Swiss culture with its value orientations. Knowledge about cultural scripts of trauma sequelae may provide a culture-specific framework that can help to understand individual experiences of distress and enable mental health practitioners to administer culturally sensitive interventions. Pending further validation, the Swiss CSTI bears the potential to advance culture-sensitive assessment of trauma sequelae.

ABSTRACT

The ICD-11 features a new group of disorders specifically associated with stress, which are interlinked by various symptoms, such as intrusive memory symptoms. Although research interest in these new ICD-11 diagnoses is growing rapidly, so far, no studies have systematically investigated the transdiagnostic distribution of stress-associated symptoms in these disorders. In the present study, 447 individuals completed a series of online questionnaires, which measured various stress-associated symptoms, e.g., flashbacks, preoccupation or yearning. Findings showed that the majority of correlations between the measured psychopathological constructs was between 0.30 and 0.60. Furthermore, with regard to specific diagnostic groups, a complex variation of stress-associated symptoms was observed, with preoccupation as a predominant symptom in all disorders. Results demonstrate that stress-associated symptoms are inherently interconnected yet possess an individual variation in different disorders. Furthermore, findings illustrate that preoccupation represents a major feature in all stress-associated disorders.

ABSTRACT

In the ICD-11 diagnostic guidelines, preoccupation has been introduced as the new core symptom of adjustment disorder. Despite this essential innovation, preoccupation has so far largely been defined as rumination and worry and does not feature a distinct character as an independent symptom. In order to investigate the nature of preoccupation, various cognitive approaches are evaluated and linked to preoccupation. Furthermore, the aim of this review is to define preoccupation more precisely and to distinguish it from other symptoms in psychopathology. The evaluation of key features of cognitive dissonance theory, attention bias theory, memory theories, and other cognitive paradigms indicates that preoccupation is constituted by a complex interaction of cognitive-emotional mechanisms. In addition, this review implies that preoccupation in AjD can be defined as stressor-related factual thinking, which is time-consuming and often associated with negative emotions. It is assumed that rumination and dysfunctional worry serve as reactive processes to cope with preoccupation. For further distinction, this review presents similarities and differences of preoccupation and other symptoms, including negative automatic thoughts, flashbacks, and yearning. Finally, implications and suggestions for future research on preoccupation are offered. Overall, it is plausible that preoccupation is not only associated with adjustment disorder but also possesses a transdiagnostic character.

ABSTRACT

Background: After almost three decades of ICD-10 use for diagnostic purposes, the World Health Organization has conducted a systematic and elaborate evaluation to revise the classification of mental disorders in this system. This revision resulted in the 11th version (ICD-11), introduced in 2022. As one new feature, the ICD-11 forms a new grouping of mental disorders specifically associated with stress. Method: The current review presents an overview of the diagnostic features and cultural specifications of disorders specifically associated with stress. This grouping includes posttraumatic stress disorder and complex posttraumatic stress disorder, prolonged grief disorder, adjustment disorder, as well as two diagnoses for children, reactive attachment disorder and disinhibited social engagement disorder. Results: Overall, there is evidence for the improved clinical utility and applicability of these disorders. The disorders have been defined in a parsimonious way by few features, but they suffice for scientific purposes as well. Conclusion: However, more research is needed to evaluate assessments for the diagnoses and diagnostic features in the ICD-11.

ABSTRACT

BACKGROUND: A fixed dose of cefazolin results in serum concentrations that decrease as body mass increases. Current national guidelines suggest a pre-operative cefazolin dose of two grams may be insufficient for patients ≥120 kg; thus a three gram dose is recommended. These recommendations, however, are based on pharmacokinetic rather than outcome data. We evaluate the efficacy of pre-operative cefazolin two gram and three gram doses as measured by the rate of surgical site infection (SSI). PATIENTS AND METHODS: We conducted a retrospective review of adult patients ≥100 kg who were prescribed cefazolin as surgical prophylaxis between September 1, 2012 and May 31, 2013 at an academic medical center. Patients were excluded if cefazolin was prescribed but not administered, had a known infection at the site of surgery, or inappropriately received cefazolin prophylaxis based on surgical indication. The SSIs were identified by documentation of SSI in the medical record or findings consistent with the standard Centers for Disease Control and Prevention definition. Inpatient and outpatient records up to 90 days post-operative were reviewed for delayed SSI. RESULTS: Four hundred eighty-three surgical cases were identified in which pre-operative cefazolin was prescribed. Forty-seven patients were excluded leaving a total of 436 patients for final analysis: 152 in the cefazolin two gram group and 284 in the three gram group. Baseline demographics were similar between groups with a mean follow-up duration of 77 days for both groups. Unadjusted SSI rates were 7.2% and 7.4% (odds ratio [OR] 0.98, p = 0.95), for the two gram and three gram groups, respectively. When differences in follow-up between groups were considered and logistic regression was adjusted with propensity score, there remained no difference in SSI rates (OR 0.87, 95% confidence interval 0.36-2.06, p = 0.77). CONCLUSION: In otherwise similar obese surgical patients weighing ≥100 kg, the administration of a pre-operative cefazolin two gram dose is associated with a similar rate of SSI compared with patients who received a three gram dose.

ABSTRACT

Rosmarinic acid and chlorogenic acid are caffeic acid esters widely found in the plant kingdom and presumably accumulated as defense compounds. In a survey, more than 240 plant species have been screened for the presence of rosmarinic and chlorogenic acids. Several rosmarinic acid-containing species have been detected. The rosmarinic acid accumulation in species of the Marantaceae has not been known before. Rosmarinic acid is found in hornworts, in the fern family Blechnaceae and in species of several orders of mono- and dicotyledonous angiosperms. The biosyntheses of caffeoylshikimate, chlorogenic acid and rosmarinic acid use 4-coumaroyl-CoA from the general phenylpropanoid pathway as hydroxycinnamoyl donor. The hydroxycinnamoyl acceptor substrate comes from the shikimate pathway: shikimic acid, quinic acid and hydroxyphenyllactic acid derived from l-tyrosine. Similar steps are involved in the biosyntheses of rosmarinic, chlorogenic and caffeoylshikimic acids: the transfer of the 4-coumaroyl moiety to an acceptor molecule by a hydroxycinnamoyltransferase from the BAHD acyltransferase family and the meta-hydroxylation of the 4-coumaroyl moiety in the ester by a cytochrome P450 monooxygenase from the CYP98A family. The hydroxycinnamoyltransferases as well as the meta-hydroxylases show high sequence similarities and thus seem to be closely related. The hydroxycinnamoyltransferase and CYP98A14 from Coleus blumei (Lamiaceae) are nevertheless specific for substrates involved in RA biosynthesis showing an evolutionary diversification in phenolic ester metabolism. Our current view is that only a few enzymes had to be "invented" for rosmarinic acid biosynthesis probably on the basis of genes needed for the formation of chlorogenic and caffeoylshikimic acid while further biosynthetic steps might have been recruited from phenylpropanoid metabolism, tocopherol/plastoquinone biosynthesis and photorespiration.

ABSTRACT

The final reactions of rosmarinic acid biosynthesis, the introduction of the aromatic 3- and 3'-hydroxyl groups, are catalysed by cytochrome P450-dependent hydroxylases. The cDNAs encoding CYP98A14 as well as a NADPH:cytochrome P450 reductase (CPR) were isolated from Coleus blumei and actively expressed in Saccharomyces cerevisiae. The CYP98A14-cDNA showed an open reading frame of 1521 nucleotides with high similarities to 4-coumaroylshikimate/quinate 3-hydroxylases. Yeast microsomes harbouring the CYP98A14 protein catalysed the 3-hydroxylation of 4-coumaroyl-3',4'-dihydroxyphenyllactate and the 3'-hydroxylation of caffeoyl-4'-hydroxyphenyllactate, in both cases forming rosmarinic acid. Apparent K (m)-values for 4-coumaroyl-3',4'-dihydroxyphenyllactate and caffeoyl-4'-hydroxyphenyllactate were determined to be at 5 microM and 40 microM, respectively. CYP98A14 differs from CYP98s from other plants, since 4-coumaroylshikimate or -quinate were not accepted as substrates. Coexpression of the Coleus blumei CPR and CYP98A14 in the same yeast cells increased the hydroxylation activity up to sevenfold. CYP98A14 from Coleus blumei is a novel bifunctional cytochrome P450 specialised for rosmarinic acid biosynthesis.
