Dopamine D2 Receptor Occupancy Estimated From Plasma Concentrations of Four Different Antipsychotics and the Subjective Experience of Physical and Me…
2019
Background Impaired subjective well-being in schizophrenia patients treated with antipsychotics has often been linked inter alia to the antidopaminergic effects of medication. Thus, it is important to capture the association between striatal dopamine D2 receptor occupancy (D2-RO) and global subjective well-being. We examined this association using data from our multicenter, randomized, double-blind Neuroleptic Strategy Study (NeSSy). Methods An innovative double randomization process was used for allocation of patients to the specific treatment groups. Plasma drug concentrations were measured after 6 and 24 weeks of treatment to obtain the estimated D2-RO (eD2-RO) relative to literature val…
Insight in schizophrenia–course and predictors during the acute treatment phase of patients suffering from a schizophrenia spectrum disorder
2012
AbstractBackgroundTo analyse insight of illness during the course of inpatient treatment, and to identify influencing factors and predictors of insight.MethodsInsight into illness was examined in 399 patients using the item G12 of the Positive and Negative Syndrome Scale (“lack of insight and judgement”). Ratings of the PANSS, HAMD, UKU, GAF, SOFAS, SWN-K and Kemp's compliance scale were performed and examined regarding their potential association with insight. The item G12 was kept as an ordinal variable to compare insight between subgroups of patients.ResultsAlmost 70% of patients had deficits in their insight into illness at admission. A significant improvement of impairments of insight …
Gene-environment interaction as a predictor of early adjustment in first episode psychosis.
2017
Abstract Background This study aims to explore the gene-environment interaction hypothesis applied to pre-symptomatic neurodevelopmental phenotypes of first episode psychosis (FEP), that is, genetic factors might increase vulnerability to the effects of environmental adverse conditions occurring at later stages of development. Methods We constructed a schematic ‘two-hit’ model, with Val/Val homozygosity for the catechol- O -methyltransferase ( COMT ) Val158Met polymorphism as the ‘first hit’ and history of obstetric complications and parental socioeconomic status as ‘second hits’. Early adjustment, measured using the Premorbid Adjustment Scale, was considered the main outcome. The study pop…
Cerebellar parcellation in schizophrenia and bipolar disorder
2019
International audience; Objective: The cerebellum is involved in cognitive processing and emotion control. Cerebellar alterations could explain symptoms of schizophrenia spectrum disorder (SZ) and bipolar disorder (BD). In addition, literature suggests that lithium might influence cerebellar anatomy. Our aim was to study cerebellar anatomy in SZ and BD, and investigate the effect of lithium.Methods: Participants from 7 centers worldwide underwent a 3T MRI. We included 182 patients with SZ, 144 patients with BD, and 322 controls. We automatically segmented the cerebellum using the CERES pipeline. All outputs were visually inspected.Results: Patients with SZ showed a smaller global cerebellar…
Patients’ health locus of control and preferences about the role that they want to play in the medical decision-making process
2021
Health locus of control (HLOC) may influence people’s behavior regarding their health as well as their desires to be involved in the medical decision-making. Our study aimed to examine HLOC’s relations with people’s control preferences about the medical decision-making. A total of 153 people filled out the self-administered version of the Control Preference Scale and the Multidimensional Health Locus of Control Scale–form C. The most preferred role is the collaborative one. However, HLOC explained heterogeneity in people’s control preferences: lower scores in external HLOC were related to a greater preference for the active and the collaborative role. From the personalized medicine perspect…
Increased Risk of Rehospitalization for Acute Diabetes Complications and Suicide Attempts in Patients With Type 1 Diabetes and Comorbid Schizophrenia
2018
OBJECTIVE The aim of this large retrospective cohort study was to estimate the supplementary morbidity and mortality risks conferred by the co-occurrence of schizophrenia among young people with type 1 diabetes. RESEARCH DESIGN AND METHODS This nationwide population-based study included individuals aged 15–35 years hospitalized in France for type 1 diabetes from 2009 to 2012 with or without schizophrenia. For assessment of the occurrence of rehospitalization for acute diabetes complications, suicide attempts, and hospital mortality, multivariate logistic regressions and survival analysis adjusted for age, sex, and Charlson comorbidity index scores were performed. The association between ho…
Effects of age on depressive symptomatology and response to antidepressant treatment in patients with major depressive disorder aged 18 to 65 years
2020
Background: There is evidence that symptomatology in patients with major depressive disorder (MDD) changes with age. However, studies comparing depressive symptomatology between different age groups during antidepressant therapy are rare. We compared demographic and clinical characteristics in depressed patients of different age groups at baseline and during treatment. Methods: 889 MDD inpatients were divided into four age groups (18–29, 30–39, 40–49, 50–65 yrs.). Demographic and clinical characteristics including depressive symptomatology (assessed by the Inventory of Depressive Symptoms) were assessed at baseline and weekly during treatment. Results: At baseline, young patients (18–29 yea…
Remission in schizophrenia — What are we measuring? Comparing the consensus remission criteria to a CGI-based definition of remission and to remissio…
2019
Despite being recommended for use in clinical trials, the consensus remission criteria were found to leave patients with persisting symptoms, relevant areas of functional impairment and a decreased sense of wellbeing. Therefore, to evaluate the appropriateness of the schizophrenia consensus criteria, a definition of remission based on the Clinical Global Impression Scale (CGI) was developed and remitter subgroups were compared.239 patients with a schizophrenia spectrum disorder were evaluated regarding their remission status after inpatient treatment. Remission in schizophrenia was defined according to the symptom-severity component of the consensus criteria by Andreasen et al. and a CGI ba…
Psychiatric Comorbidity at the Time of Diagnosis in Adults With ADHD: The CAT Study.
2016
Objective: The CAT ( Comorbilidad en Adultos con TDAH) study aimed to quantify and characterize the psychiatric comorbidity at the time of diagnosis of ADHD in adult outpatients. Method: Cross-sectional, multicenter, observational register of adults with ADHD diagnosed for the first time. Results: In this large sample of adult ADHD ( n = 367), psychiatric comorbidities were present in 66.2% of the sample, and were more prevalent in males and in the hyperactive-impulsive and combined subtypes. The most common comorbidities were substance use disorders (39.2%), anxiety disorders (23%), and mood disorders (18.1%). In all, 88.8% patients were prescribed pharmacological treatment for ADHD (in 9…
Psychological distress associated with the COVID-19 lockdown: A two-wave network analysis
2021
Abstract Background Although preliminary research has evidenced negative psychological consequences of the COVID-19 pandemic among the general population, little research has been carried out examining the interplay among the broader dimensions and correlates of individual distress. Via network analysis, the current study investigated the pathways that underlie some components of psychological distress and their changes over time (during and post COVID-19-related lockdown). Methods 1,129 adult participants (79.1% women) completed a two-wave online survey during and after the lockdown, and reported on variables such as depression, anxiety, stress, fear of COVID, intolerance of uncertainty, e…
