Heart rate variability is not associated with multiple chemical sensitivity in a cross-sectional population-based study - The Danish study of functional disorders.

Objective: Multiple chemical sensitivity (MCS), a functional somatic disorder (FSD), is a multisystem, polysymptomatic disease, characterized by various individual symptoms attributed to low level of volatile chemical exposures. Symptoms relate to the autonomic nerve system (ANS) among others which is mandatory in the MCS delimitations. An accepted measure of ANS is heart rate variability (HRV).

Use and discontinuation of antipsychotic medication in 20 years following a first episode of schizophrenia: results from the OPUS trial.

Introduction: Short-term exposure to antipsychotics has proven to be beneficial. However, naturalistic studies are lacking regarding the long-term use of antipsychotics. This study aimed to investigate changes in use of antipsychotics over 20 years after a first-episode schizophrenia.

Cognition Assessment in Virtual Reality (CAVIR): Associations with neuropsychological performance and activities of daily living in patients with mood or psychosis spectrum disorders.

Background: More ecologically valid tools are needed to better capture daily-life cognitive impairments in patients with mood or psychosis spectrum disorders in clinical settings and cognitive treatment trials. We developed the Cognition Assessment in Virtual Reality (CAVIR) test, which assesses daily-life cognitive skills in an immersive virtual reality kitchen scenario. This study investigated the validity and sensitivity of CAVIR, including its association with activities of daily living (ADL) ability.

Lifestyle factors as predictors of incident functional somatic disorder. Five-year follow-up of The DanFunD study.

Aims: To assess whether lifestyle factors, including sleep pattern, are predictors for the development of functional somatic disorder (FSD).

Methods: A population-based prospective cohort of 9656 men and women aged 18-76 years was established in 2011-2015 and invited for re-examination in 2017-2020, when 5738 participated. Median follow-up period was 65 months.

Psychotic and negative symptoms are core features of schizophrenia but knowledge on the long-term course of these symptoms is lacking. While antipsychotics improve psychotic symptoms, they have limited effect on negative symptoms. Specialized early interventions like OPUS show great effects while ongoing but long-term follow-up indicates no lasting disease-modifying effects.

Relation of Insulin Resistance to Brain Glucose Metabolism in Fasting and Hyperinsulinemic States: A Systematic Review and Meta-Analysis.

Context: Abnormal brain glucose metabolism may cause cognitive disease in type 2 diabetes, yet the relation between insulin resistance and brain glucose metabolism has not been systematically described.

Objective: We evaluated the impact of metabolic condition (fasting vs insulin stimulation, e.g.

Clinical illness course and family-related outcomes among parents with a first episode of schizophrenia spectrum disorder: a 20-year follow-up of the OPUS trial.

Background: Studies investigating parenthood and how it affects long-term outcomes are lacking among individuals with schizophrenia spectrum disorders. This study aimed to examine the life of participants 20 years after their first diagnosis with a special focus on parenthood, clinical illness course, and family-related outcomes.

Methods: Among 578 individuals diagnosed with first-episode schizophrenia spectrum disorder between 1998 and 2000, a sample of 174 participants was reassessed at the 20-year follow-up.

Is reduced heart rate variability associated with functional somatic disorders? A cross-sectional population-based study; DanFunD.

Objectives: It has been hypothesised that functional somatic disorders (FSD) could be initiated by sympathetic predominance in the autonomic nervous system as measured by low heart rate variability (HRV). Earlier studies on the association between HRV and FSD are small case-control studies hampered by selection bias and do not consider the great overlap between the various FSDs. The aim of the present study is to assess any associations between HRV and various FSDs and whether chronic stress confounds such an association.

Effect of immersive virtual reality-based cognitive remediation in patients with mood or psychosis spectrum disorders: study protocol for a randomized, controlled, double-blinded trial.

Background: Cognitive impairments are prevalent across mood disorders and psychosis spectrum disorders, but there is a lack of real-life-like cognitive training programmes. Fully immersive virtual reality has the potential to ensure motivating and engaging cognitive training directly relevant to patients' daily lives. We will examine the effect of a 4-week, intensive virtual reality-based cognitive remediation programme involving daily life challenges on cognition and daily life functioning in patients with mood disorders or psychosis spectrum disorders and explore the neuronal underpinnings of potential treatment efficacy.

Treatment of schizotypal disorder: a protocol for a systematic review of the evidence and recommendations for clinical practice.

Introduction: Schizotypal disorder is associated with a high level of disability at an individual level and high societal costs. However, clinical recommendations for the treatment of schizotypal disorder are scarce and based on limited evidence. This review aims to synthesise the current evidence on treatment for schizotypal disorder making recommendations for clinical practice.

Are Sexual Assaults Related to Functional Somatic Disorders? A Cross-Sectional Study.

An increasing number of sexual assaults (SAs) are being reported. This study investigated associations between SA and FSD, conceptualized as bodily distress syndrome (BDS), and five functional somatic syndromes (FSSs): chronic widespread pain (CWP), irritable bowel (IB), chronic fatigue (CF), multiple chemical sensitivity (MCS), and whiplash-associated disorder (WAD). Participants ( = 7493) from the population-based cohort Danish Study of Functional Disorders (DanFunD) completed questionnaires on FSD, emotional distress, SA, and sociodemographics.

Children at Familial High risk of Schizophrenia and Bipolar Disorder Exhibit Altered Connectivity Patterns During Pre-attentive Processing of an Auditory Prediction Error.

Background And Hypothesis: Individuals with schizophrenia or bipolar disorder have attenuated auditory mismatch negativity (MMN) responses, indicating impaired sensory information processing. Computational models of effective connectivity between brain areas underlying MMN responses show reduced connectivity between fronto-temporal areas in individuals with schizophrenia. Here we ask whether children at familial high risk (FHR) of developing a serious mental disorder show similar alterations.

Integrated mental healthcare and vocational rehabilitation for people on sick leave with stress-related disorders: 24-month follow-up of the randomized IBBIS trial.

Objectives: Integrating vocational rehabilitation and mental healthcare has shown effects on vocational outcomes during sick leave with common mental disorders. In a previous paper, we showed that a Danish integrated healthcare and vocational rehabilitation intervention (INT) had a surprisingly negative impact on vocational outcomes compared to service as usual (SAU) at 6- and 12-month follow-up. That was also the case with a mental healthcare intervention (MHC) tested in the same study.

Integrated Mental Healthcare and Vocational Rehabilitation for People on Sick Leave with Anxiety or Depression: 24-Month Follow-up of the Randomized IBBIS Trial.

Integration of vocational rehabilitation and mental healthcare has shown some effect on work participation at 1-year follow-up after sick leave with depression and anxiety. We aimed to study the effect on work and health outcomes at 2-year follow-up, why we performed a randomized trial was conducted to study the effectiveness of integrated intervention (INT) compared to service as usual (SAU) and best practice mental healthcare (MHC). We included 631 participants, and at 24-month follow-up, we detected no differences in effect between INT and SAU.

Clinical Recovery and Long-Term Association of Specialized Early Intervention Services vs Treatment as Usual Among Individuals With First-Episode Schizophrenia Spectrum Disorder: 20-Year Follow-up of the OPUS Trial.

Importance: The OPUS 20-year follow-up is the longest follow-up of a randomized clinical trial testing early intervention services (EIS) among individuals with first-episode schizophrenia spectrum disorder.

Objective: To report on long-term associations of EIS compared with treatment as usual (TAU) for first-episode schizophrenia spectrum disorder.

Design, Setting, And Participants: A total of 547 individuals were included in this Danish multicenter randomized clinical trial between January 1998 and December 2000 and allocated to early intervention program group (OPUS) or TAU.

Affective lability in parents with schizophrenia or bipolar disorder and their co-parents - The Danish High Risk and Resilience Study VIA 7.

In bipolar disorder, dysregulation of affect is a core feature while knowledge on affective lability in schizophrenia is sparse. Research on affective lability in partners to individuals with schizophrenia or bipolar disorder is also lacking. The objective of this study was to investigate affective lability in parents with schizophrenia or bipolar disorder, and their co-parents without these disorders.

Effect of mode of birth on development of mental disorders in the offspring.

Objective: Increasing rates of caesarean sections has led to concerns about long-term effects on the offspring's health, and it has been hypothesised that caesarean section induced differences in the child's microbiota could potentially increase the risk of mental disorders.

Methods: Nationwide Danish cohort study of 2,196,687 births was conducted between 1980 and 2015, with 38.5 million observation-years.

Premorbid functioning in adolescence associates with comorbid disorders in individuals at ultra-high risk for psychosis: A brief report.

Aim: This study examines associations between premorbid adjustment and comorbid disorders in individuals at ultra-high risk (UHR) for psychosis.

Methods: Premorbid social and academic adjustment data were collected from 146 UHR individuals using the Premorbid Adjustment Scale. Comorbid disorders were determined by the Structural Clinical Interview for DSM-IV.

Association Between Early Risk Factors and Level of Functioning at Age Seven in Children at Familial Risk for Schizophrenia Or Bipolar Disorder - the Danish High Risk and Resilience Study VIA 7.

Background: Facing multiple risk factors, relative to single risk factor exposure early in life can have great implications for negative child development.

Objective: We aim to examine whether the prevalence of early risk factors is higher among children with familial high risk for schizophrenia or bipolar disorder compared to controls. Further, to investigate the association between number of early risk factors and level of functioning at age seven, and whether this possible association is different in children with familial high risk compared to controls.

Association between infections and functional somatic disorders: a cross-sectional population-based cohort study.

Objectives: It has been suggested that infections can trigger functional somatic disorders (FSD). However, current evidence is limited by inconsistent findings in smaller studies conducted in clinical settings within selected populations and short follow-up times. We aimed to test the hypothesis that former infections are associated with FSD using data from nationwide registries and a large population-based cohort study, the Danish Study of Functional Disorders study.

Time trends in co-occurring substance use and psychiatric illness (dual diagnosis) from 2000 to 2017 - a nationwide study of Danish register data.

Objective: This article aims to describe the time trend in number of dual diagnosis patients treated in the psychiatric system in Denmark from 2000 to 2017.

Method: We calculated the share of patients with dual diagnosis, number of dual diagnosis contacts, number of unique individuals with dual diagnosis as well as number of new patients with dual diagnosis among patients in psychiatric treatment, i.e.

Examine the public health impacts of functional somatic disorders using the DanFunD study.

Persistent physical symptoms (e.g. pain, fatigue) are prevalent in the population and some persons may develop a functional somatic disorder (FSD).

The effect of an integrated care intervention of multidisciplinary mental health treatment and employment services for trauma-affected refugees: study protocol for a randomised controlled trial.

Background: The complexity of past trauma and ongoing post-migration stressors challenges the existing mental health treatment for trauma-affected refugees. Therefore, interventions are needed to accommodate these complex challenges in mental health treatment. This study examines the effect of an add-on integrated care intervention compared to treatment as usual (TAU) for trauma-affected refugees in a randomised controlled trial (RCT).
