Impact of childhood trauma on antipsychotic effectiveness in schizophrenia spectrum disorders: A prospective, pragmatic, semi-randomized trial

Antipsychotic medications are generally effective in ameliorating psychotic symptoms in schizophrenia spectrum disorders (SSDs). Identifying predictors associated with poor treatment response is important for a personalized treatment approach. Childhood trauma (CT) may have a general and differential effect on the effectiveness of different types of antipsychotics in SSDs. The Bergen-Stavanger-Trondheim-Innsbruck (BeSt InTro) study is a pragmatic, researcher-initiated, semi-randomized trial. The present study aimed to investigate symptom change (the Positive and Negative Syndrome Scale) from baseline to 1, 3, 6, 12, 26, 39 and 52 weeks of antipsychotic treatment (amisulpride, aripiprazole and olanzapine) by group (CT/no CT). Participants (n = 98) with diagnoses within the schizophrenia spectrum (F20–29 in the International Classification of Diseases — 10th Revision) were randomized to receive amisulpride, aripiprazole or olanzapine, and for this study categorized into groups of none and low CT, and moderate to severe CT according to thresholds defined by the Childhood Trauma Questionnaire Short-Form manual. CT in SSDs predicted an overall slower treatment response and less antipsychotic effectiveness after 26 weeks of treatment, which was statistically nonsignificant at 52 weeks. Secondary analyses showed a differential effect of CT related to type of antipsychotic medication: patients with SSDs and CT who received olanzapine showed less antipsychotic effectiveness throughout 52 weeks of treatment. The intention-to-treat and per-protocol analyses were convergent. Our findings indicate that in patients with SSD and CT, delayed response to antipsychotics could be expected, and a longer evaluation period before considering change of medication may be recommended.publishedVersio

Does childhood trauma influence cognitive functioning in schizophrenia? The association of childhood trauma and cognition in schizophrenia spectrum disorders.

Childhood trauma (CT) is a risk factor for schizophrenia spectrum disorders (SSDs), and cognitive impairment is a core feature and a vulnerability marker of SSDs. Studies of the relationship between CT and cognitive impairment in SSDs are inconclusive. In addition, few studies have examined differential effects of CT subtypes, e.g. physical, sexual or emotional abuse/neglect, on cognitive functioning. The present study therefore aimed to examine the effects of CT and CT subtypes on cognitive impairment in SSD. Participants (n = 78) with SSDs completed a comprehensive neuropsychological test battery and the Childhood Trauma Questionnaire Short-Form (CTQ-SF). We compared global cognitive performance as well as scores in seven subdomains (verbal abilities, visuospatial abilities, learning, memory, attention/working memory, executive abilities and processing speed) between participants reporting no CT and those reporting CT experiences using independent samples t-tests as well as linear regression analyses to control for possible confounders. CT subtype physical neglect was associated with attention and working memory after controlling for positive and negative psychosis symptoms, years of education, antipsychotics, gender and age, and adjustment of multiple testing. Our results indicate that the observed heterogeneity in cognitive impairment in SSDs, especially attention/working memory abilities, may in part be associated with childhood physical neglect

The Creative Commons Public Domain Dedication waiver (http://creativecommons.org/publicdomain/zero/1.0/) applies to the data made available in this article, unless otherwise stated.BACKGROUND: Pregnant women who gain excess weight are at risk of complications during pregnancy and in the long term. Interventions based on diet and physical activity minimise gestational weight gain with varied effect on clinical outcomes. The effect of interventions on varied groups of women based on body mass index, age, ethnicity, socioeconomic status, parity, and underlying medical conditions is not clear. Our individual patient data (IPD) meta-analysis of randomised trials will assess the differential effect of diet- and physical activity-based interventions on maternal weight gain and pregnancy outcomes in clinically relevant subgroups of women. METHODS/DESIGN: Randomised trials on diet and physical activity in pregnancy will be identified by searching the following databases: MEDLINE, EMBASE, BIOSIS, LILACS, Pascal, Science Citation Index, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects, and Health Technology Assessment Database. Primary researchers of the identified trials are invited to join the International Weight Management in Pregnancy Collaborative Network and share their individual patient data. We will reanalyse each study separately and confirm the findings with the original authors. Then, for each intervention type and outcome, we will perform as appropriate either a one-step or a two-step IPD meta-analysis to obtain summary estimates of effects and 95% confidence intervals, for all women combined and for each subgroup of interest. The primary outcomes are gestational weight gain and composite adverse maternal and fetal outcomes. The difference in effects between subgroups will be estimated and between-study heterogeneity suitably quantified and explored. The potential for publication bias and availability bias in the IPD obtained will be investigated. We will conduct a model-based economic evaluation to assess the cost effectiveness of the interventions to manage weight gain in pregnancy and undertake a value of information analysis to inform future research.

Childhood Trauma in Schizophrenia Spectrum Disorders: A comparison to substance abuse disorders, and relation to cognitive performance and antipsychotic treatment outcomes

An increasing body of research points to the importance of childhood trauma (CT) in psychosis, and as a risk factor for schizophrenia spectrum disorders (SSDs). The aim of this thesis was to investigate and compare the frequency and severity of CT in relation to clinical aspects and treatment outcomes in SSDs. The Childhood Trauma Questionnaire Short-Form (CTQ-SF) was used to retrospectively measure overall exposure to CT and CT subtypes (physical, sexual, and emotional abuse, and physical and emotional neglect). Paper I examined the specificity of CT in SSDs, and showed no group differences between patients with SSDs and patients with substance use disorders (SUDs) when comparing CTQ-SF sum and subscale scores, as well as no differences in the frequency and severity in the reported CT. Paper II examined the potential effect of CT on cognition in SSDs. No overall group differences emerged between SSD patients with CT compared to those reporting no CT. However, the CT subtype physical neglect predicted impaired attention/working memory abilities in SSDs. Paper III examined the influence of CT on general and differential antipsychotic effectiveness in SSDs. There were no differences for general antipsychotic effectiveness at 52 weeks for SSDs patients with CT as compared to the no CT group. However, for the olanzapine subgroup, the CT group showed less decrease in overall psychosis symptoms form baseline to 12, 26, 39 and 52 weeks. Findings from the current thesis suggest that CT is frequently reported in SSDs, although not unique nor specific for SSDs in comparison to SUDs. The CT subtype neglect appears to be related to clinically relevant features associated with SSDs such as cognitive performance, possibly reflecting a cognitive vulnerability for psychosis. Additionally, our findings indicate that CT may be associated with a slower antipsychotic treatment response to olanzapine in SSDs, even though the overall effect of CT was minimal. Clinicians and patients with SSDs and SUDs could benefit from integrating information regarding CT exposure in routine clinical settings

The treatment of PTSD in an older adult Norwegian woman using narrative exposure therapy: a case report

The bulk of the literature on effective treatments for posttraumatic stress disorder (PTSD) has focused on children, adolescents, and young adults. The evidence on treatments for older adults is sparse. This case report presents the application of narrative exposure therapy (NET) for a 70-year-old Norwegian woman suffering from PTSD as a result of multiple childhood and late life traumatic events. NET is a manualized, short-term, cognitive-behavioural therapy for PTSD, originally developed to meet the needs of survivors of war and organized violence. Some aspects of NET may be a good fit for older adults, including its brevity, simplicity, and concrete nature. The course of therapy included psychoeducation, a lifeline exercise, imaginal exposure, and the creation of a coherent narrative. Symptoms of depression and posttraumatic stress showed improvement over the course of therapy and at follow-up. This suggests that NET may have potential as a trauma treatment for older adults

Impact of job adjustment, pain location and exercise on sick leave due to lumbopelvic pain in pregnancy: a longitudinal study

Objective: To identify factors associated with sick leave due to lumbopelvic pain (LPP) in pregnancy. Design: Prospective cohort study using participants from a randomized controlled trial (RCT) designed to study the effect of exercise during pregnancy on pregnancy related diseases. Setting: St. Olavs Hospital, Trondheim University Hospital and Stavanger University Hospital, April 2007 to December 2009. Subjects: Healthy pregnant women. Main outcome measures: Self-reported sick leave due to LPP in late pregnancy (gestation week 32–36). Results: In total, 532/716 (74%) women reported LPP at 32–36 weeks of pregnancy, and 197/716 (28%) reported sick leave due to LPP. Not receiving job adjustments when needed (Odds ratio, OR with 95% confidence interval, CI, was 3.0 (1.7–5.4)) and having any pain in the pelvic girdle versus no pain (OR 2.7 (1.3–5.6), OR 2.7 (1.4–5.2) and OR 2.2 (1.04–4.8)) for anterior, posterior and combined anterior and posterior pain in the pelvis respectively, were associated with sick leave due to LPP in late pregnancy. Also higher disability, sick listed due to LPP at inclusion and lower education, were significant explanatory variables. There was a trend of reduced risk for sick leave due to LPP when allocated to the exercise group in the original RCT (OR 0.7 (0.4–1.0)). Conclusion: Facilitating job adjustments when required might keep more pregnant women in employment. Furthermore, pain locations in pelvic area, disability, lower education and being sick listed due to LPP in mid pregnancy are important risk factors for sick leave in late pregnancy.Key points Current awareness: More than half of pregnant women are on sick leave during pregnancy and the most frequently reported cause is lumbopelvic pain. This paper adds:Inability to make job adjustments, pain locations in pelvic area, disability and lower education level were the most important risk factors for sick leave in late pregnancy. Facilitating early job adjustment might be a precaution to keep more pregnant women in work. Allocation to an exercise group tended to reduce the risk of sick leave in late pregnancy.Registration number: Clinical trial gov (NCT 00476567)
