- Frontal cortical abnormalities and executive function impairment co-occur in bipolar disorder. Recent studies have shown that bipolar subtypes differ in the degree of structural and functional impairments. The relationships between cognitive performance and cortical integrity have not been clarified and might differ across patients with bipolar disorder type I, II, and healthy subjects.Using a vertex-wise whole-brain analysis, we investigated how cortical integrity, as measured by cortical thickness, correlates with executive performance in patients with bipolar disorder type I, II, and controls (N = 160).We found focal associations between executive function and cortical thickness in the medial prefrontal cortex in bipolar II patients and controls, but not in bipolar I disorder. In bipolar II patients, we observed additional correlations in lateral prefrontal and occipital regions.Our findings suggest that bipolar disorder patients show altered structure-function relationships, and importantly that those relationships may differ between bipolar subtypes. The findings are line with studies suggesting subtype-specific neurobiological and cognitive profiles. This study contributes to a better understanding of brain structure-function relationships in bipolar disorder and gives important insights into the neuropathophysiology of diagnostic subtypes.

- Objective: Pedophilic disorder (PD) is characterized bypersistent, intense sexual attraction to prepubertal children that the individual has acted on, or causes marked distress or interpersonal difficulty. Although prior research suggests that PD has neurodevelopmental underpinnings, the evidence remains sparse. To aid the understanding of etiology and treatment development, we quantified neurobiological and clinical correlates of PD.Method: We compared 55 self-referred, help-seeking, non-forensic male patients with DSM-5 PD with 57 age-matched, healthy male controls (HC) on clinical, neuropsychological, and structural brain imaging measures (cortical thickness and surface area, subcortical and white matter volumes). Structural brain measures were related to markers for aberrant neurodevelopment including IQ, and the 2nd to 4th digit ratio (2D:4D).Results: PD was associated with psychiatric disorder comorbidity and ADHD and autism spectrum disorder symptoms. PD patients had lower total IQ than HC. PD individuals exhibited cortical surface area abnormalities in regions belonging to the brain's default mode network and showed abnormal volume of white matter underlying those regions. PD subjects had smaller hippocampi and nuclei accumbens than HC. Findings were not related to history of child-related sexual offending. IQ correlated negatively with global expression of PD-related brain features and 2D:4D correlated with surface area in PD.Conclusions: In the largest single-center study to date, we delineate psychiatric comorbidity, neurobiological and cognitive correlates of PD. Our morphometric findings, their associations with markers of aberrant neurodevelopment, and psychiatric comorbidities suggest that neurodevelopmental mechanisms are involved in PD. The findings may need consideration in future development of clinical management of PD patients.

- Objective: Mental illness is increasing among young people and likewise the request for health care services. At the same time, somatic comorbidity is common in children and adolescents with psychiatric disorders. There is a lack of studies on health care use in children and adolescents, and the hypothesis was that children and adolescents with psychiatric disorders use more primary-, and specialized somatic health care compared to children without psychiatric disorders. Methods: In this retrospective population-based register study, all individuals aged 3-17 years living in Vastra Gotaland region in Sweden in 2017 were included (n = 298,877). Linear and Poisson regression were used to compare health care use during 2016-2018 between children with and without psychiatric diagnoses, controlling for age and gender. The results were reported as unstandardised beta coefficient (beta) and adjusted prevalence ratio (aPR) respectively. Results: Having a psychiatric diagnosis was associated with more primary care visits (beta 2.35, 95% CI 2.30-2.40). This applied to most diagnoses investigated. Girls had more primary care visits than boys. Likewise, individuals with psychiatric diagnoses had more specialized somatic outpatient care (beta 1.70, 95% CI 1.67-1.73), both planned and unplanned (beta 1.23, 95% CI 1.21-1.25; beta 0.18, 95% CI 0.17-0.19). Somatic inpatient care was more common in those having a psychiatric diagnosis (aPR 1.65, 95% CI 1.58-1.72), with the diagnoses of psychosis and substance use exerting the greatest risk. Conclusions: Psychiatric diagnoses were associated with increased primary-, somatic outpatient- as well as somatic inpatient care. Increased awareness of comorbidity and easy access to relevant health care could be beneficial for patients and caregivers. The results call for a review of current health care systems with distinct division between medical disciplines and levels of health care.

- The pathophysiology behind the abnormalities of the hypothalamic pituitary adrenal cortex axis found in patients with major depressive disorder was studied by the use of the vasopressin test. The response of plasma adrenocorticotropin (ACTH) and cortisol to the injection of 10 IU lysine-vasopressin (LVP) was investigated in 18 patients meeting the DSM-III criteria for major depressive episode. The response was correlated to the outcome of the dexamethasone suppression test (DST) with the use of two different cut-off points, 139 nmol/l and 200 nmol/l respectively. The results show that no significant difference was found in ACTH or cortisol response between patients having a normal or abnormal DST. The results do not seem to support the hypothesis that the abnormalities of the hypothalamic pituitary adrenal cortex axis involve a hypersecretion of corticotropin-releasing factor (CRF) and a subsequent desensitization of the corticotrophs to CRF-stimulated ACTH release.

- Objective: This study aimed to associate antidepressants with versus without antipsychotics with readmission and suicide in patients with psychotic unipolar depression.Methods: Swedish national registers were used to identify inpatients with psychotic unipolar depression, treated 2007-2016. The participants collected antidepressants with or without antipsychotics from a pharmacy within 14 days after discharge and were followed up for 2 years. The primary outcome was hospital readmission due to any psychiatric disorder, suicide attempt, or completed suicide. Cox regression was used to analyze the data, which were adjusted for sex, age, prior admissions, comorbidity, electroconvulsive therapy, and other pharmacological treatments.Results: We identified 4391 patients, of which 2972 were in the antidepressant + antipsychotic combination therapy group, and 1419 were in the antidepressant monotherapy group. After 2 years, 42.3% and 36.6% of patients were readmitted or committed suicide in the combination therapy and monotherapy group, respectively. Monotherapy was significantly associated with a lower risk of reaching the outcome in the main analysis (hazard ratio = 0.86; 95% confidence interval: 0.77-0.95). The results went in the same direction in all sensitivity analyses.Conclusion: Our findings do not indicate any advantage of adding antipsychotics as adjunctive to antidepressants as maintenance treatment. Considering the wide use, known side effects, and the current lack of evidence supporting the benefit, further studies on the effect of antipsychotics in the maintenance phase of psychotic unipolar depression are urgently warranted.

- One hundred key informants were interviewed regarding their awareness and attitudes toward suicidal behaviour. Eighty-eight informants were male, 58 were Muslim and 42 were Christian. Informants on average, claimed to know more persons who had completed suicide than those who had attempted suicide. Almost all informants mentioned more than one cause for suicide. Of these, frustration was the most frequently mentioned cause. Most informants believed that suicide attempters are cruel, feared and not trustworthy. Their attitude toward suicide completers was expressed as condemned sinners, do not deserve funeral ceremony, and should be buried separately from others. Christians gave importance to the funeral issue more than did the Muslims. Generally, the attitudes of informants were punitive and disapproving.
