Stress-related psychopathology after cardiac surgery and intensive care treatment

Objective: Cardiac surgery patients are at risk for psychopathology. Symptoms of post-traumatic stress disorder (PTSD) and depression occur in 10–20% of these patients and affect their quality of life. The aim of this study was to assess factors associated with psychopathology after cardiac surgery. Methods: We followed participants of the multi-center randomized clinical trial Dexamethasone for Cardiac Surgery (DECS), on a single, intravenous dose of dexamethasone (1 mg/kg) or placebo during cardiac surgery, using validated questionnaires to assess PTSD and depressive symptoms after 1.5 to 4 years, as well as childhood trauma, trait anxiety, pre-existing psychopathology, and substance use. Saliva was used for genotyping of the hypothalamic-pituitary-adrenal-axis (HPA axis) glucocorticoid receptor gene. Linear backward regression analysis was performed with these factors, including pre-specified interaction terms of dexamethasone with sex and genotype. Results: Complete data was available for 90% of cases (n = 1111). The model including trait anxiety and the [dexamethasone x female sex] interaction explained 57% of variance in PTSD symptoms (Model fit F (2;4.817)=643.043, p<.001; R2=0 0.57). Similar explained variance was seen for depressive symptoms, where age, trait anxiety and the [dexamethasone x female sex] interaction provided the optimal model (Model fit F (3;4.261)=435,960, p<.001; R2=0.58). Limitations: In this study psychopathology was assessed through validated questionnaires. Variability in data collection detail was present. Conclusion: This study suggests that the occurrence of psychopathology after cardiac surgery is influenced by higher trait anxiety. Female cardiac surgery patients may benefit from intra-operative dexamethasone administration

Parental Age in Relation to Offspring's Neurodevelopment

Objective: Advanced parenthood increases the risk of severe neurodevelopmental disorders like autism, Down syndrome and schizophrenia. Does advanced parenthood also negatively impact offspring’s general neurodevelopment? Method: We analyzed child-, father-, mother- and teacher-rated attention-problems (N = 38,024), and standardized measures of intelligence (N = 10,273) and educational achievement (N = 17,522) of children from four Dutch population-based cohorts. The mean age over cohorts varied from 9.73–13.03. Most participants were of Dutch origin, ranging from 58.7%-96.7% over cohorts. We analyzed 50% of the data to generate hypotheses and the other 50% to evaluate support for these hypotheses. We aggregated the results over cohorts with Bayesian research synthesis. Results: We mostly found negative linear relations between parental age and attention-problems, meaning that offspring of younger parents tended to have more attention problems. Maternal age was positively and linearly related to offspring’s IQ and educational achievement. Paternal age showed an attenuating positive relation with educational achievement and an inverted U-shape relation with IQ, with offspring of younger and older fathers at a disadvantage. Only the associations with maternal age remained after including SES. The inclusion of child gender in the model did not affect the relation between parental age and the study outcomes. Conclusions: Effects were small but significant, with better outcomes for children born to older parents. Older parents tended to be of higher SES. Indeed, the positive relation between parenta

Transition from Child and Adolescent to Adult Mental Health Services in Young People with Depression: On What Do Clinicians Base their Recommendation?

BACKGROUND: Clinicians in Child and Adolescent Mental Healthcare Services (CAMHS) face the challenge to determine who is at risk of persistence of depressive problems into adulthood and requires continued treatment after reaching the CAMHS upper age limit of care-provision. We assessed whether risk factors for persistence were related to CAMHS clinicians’ transition recommendations. METHODS: Within the wider MILESTONE cohort study, 203 CAMHS users were classified with unipolar depressive disorder by their clinician, and 185 reported clinical levels of depressive problems on the DSM-oriented Depressive Problems scale of the Achenbach Youth Self Report. Logistic regression models were fitted to both subsamples to assess the relationship between clinicians’ transition recommendations and risk factors for persistent depression. RESULTS: Only clinicianrated severity of psychopathology was related to a recommendation to continue treatment for those classified with unipolar depressive disorder (N = 203; OR = 1 45, 95% CI (1.03–2.03), p = 044) and for those with self-reported depressive problems on the Achenbach DSM-oriented Depressive Problems scale (N = 185; OR = 1 62, 95% CI (1.12–2.34), p = 012). CONCLUSION: Transition recommendations and need for continued treatment are based on clinical expertise, rather than self-reported problems and needs

Dose response of the 16p11.2 distal copy number variant on intracranial volume and basal ganglia.

Carriers of large recurrent copy number variants (CNVs) have a higher risk of developing neurodevelopmental disorders. The 16p11.2 distal CNV predisposes carriers to e.g., autism spectrum disorder and schizophrenia. We compared subcortical brain volumes of 12 16p11.2 distal deletion and 12 duplication carriers to 6882 non-carriers from the large-scale brain Magnetic Resonance Imaging collaboration, ENIGMA-CNV. After stringent CNV calling procedures, and standardized FreeSurfer image analysis, we found negative dose-response associations with copy number on intracranial volume and on regional caudate, pallidum and putamen volumes (β = -0.71 to -1.37; P &lt; 0.0005). In an independent sample, consistent results were obtained, with significant effects in the pallidum (β = -0.95, P = 0.0042). The two data sets combined showed significant negative dose-response for the accumbens, caudate, pallidum, putamen and ICV (P = 0.0032, 8.9 × 10-6, 1.7 × 10-9, 3.5 × 10-12 and 1.0 × 10-4, respectively). Full scale IQ was lower in both deletion and duplication carriers compared to non-carriers. This is the first brain MRI study of the impact of the 16p11.2 distal CNV, and we demonstrate a specific effect on subcortical brain structures, suggesting a neuropathological pattern underlying the neurodevelopmental syndromes

Does assessment type matter? A measurement invariance analysis of online and paper and pencil assessment of the Community Assessment of Psychic Experiences (CAPE)

The psychometric properties of an online test are not necessarily identical to its paper and pencil original. The aim of this study is to test whether the factor structure of the Community Assessment of Psychic Experiences (CAPE) is measurement invariant with respect to online vs. paper and pencil assessment.status: publishe
