Introduction
Antidepressants are often used by persons with schizophrenia. These medications are used for a variety of symptoms, such as negative or depressive ones. Effectiveness of antidepressant use in persons with schizophrenia has rarely been studied in the real-world setting.
ObjectivesThe aim of this study was to investigate the risk of hospitalization due to psychosis related to antidepressant use in persons with schizophrenia.
MethodsThis cohort study utilized data combined from Finnish nationwide registers. The study cohort included all 61 889 persons treated in inpatient care due to schizophrenia (defined as International Classification of Diseases, ICD, version 10 codes F20-F25 during 1972–2014 in Finland). National Prescription register data was utilized to obtain drug purchase data, and modelled into drug use periods with PRE2DUP (From Prescriptions to Drug Use Periods) method, developed by our research group. The follow-up covered the years from 1996 to 2017. Antidepressants (Anatomic Therapeutic Chemical classification system, ATC code N06A) were categorized by mechanism of action (non-selective monoamine reuptake inhibitors, TCAs, ATC-codes N06AA, selective serotonin reuptake inhibitors, SSRIs, N06AB and serotonin-norepinephrine reuptake inhibitors, SNRIs, including venlafaxine, milnacipran and duloxetine), and also on drug-substance level. Main outcome was hospitalization due to psychosis (ICD-10 diagnoses F20-F29) as the main diagnosis. We used within-individual design to compare the risk of outcome between the time periods of antidepressant use and non-use within the same person to minimize selection bias. Stratified Cox regression analyses were utilized to calculate adjusted hazard ratios (aHR) with 95% confidence intervals (CIs). These analyses were then adjusted for sequential order of treatments, time since cohort entry, use of antipsychotics, mood stabilizers, benzodiazepines, and Z-drugs.
ResultsThe mean age of the study cohort was 46.2 (SD 16.0) years at cohort entry, and 50.3% of were males. Altogether 49.3% (N=30 508) of the study cohort used antidepressants during the follow-up (median 14.8 years, IQR 7.5-22.0), with citalopram and mirtazapine being the most commonly used antidepressants. The risk of psychosis hospitalization was lower during antidepressant use as compared to non-use (aHR 0.93, 95% CI 0.92-0.95). Use of SSRIs was associated with similar risk (aHR 0.91, 95% CI 0.89-0.93), followed by SNRIs (aHR 0.92, 95% CI 0.88-0.97) and TCAs (aHR 0.93, 95% CI 0.89-0.98). Considering individual drug substances, lowest risk were obserwed with use of sertraline (aHR 0.87, 95% CI 0.83-0.91), fluoxetine (aHR 0.88, 95% CI 0.83-0.91) and citalopram (aHR 0.92, 95% CI 0.90-0.95).
ConclusionsUse of antidepressants was associated with a 7% lowered risk of hospitalization due to psychosis, and AD subgroups did not differ in their real-world effectiveness.

Introduction
Depression markedly increases the risk of suicide, and depression is the most common psychiatric disorder diagnosed in persons with a completed suicide, but the interplay between depression and psychotic symptoms in suicides has remained unsettled.
ObjectivesThe purpose of this study was to establish the risk of suicide associated with incident psychotic depression (PD) compared to incident non-psychotic severe depression (NPD) in a large nationwide cohort.
MethodsThis cohort study used routine data from nationwide health registers in Finland. Eligible participants were aged 18 ̶ 59 years at the index diagnosis. Causes of death were defined by the International Classification of Diseases, 10th revision codes. The follow-up time was up to five years. Adjusted Cox regression models were used to analyse risk of death by method of suicide.
ResultsWe included 17331 individuals with incident PD and 85989 individuals with incident NPD. Most of the deaths due to suicides occurred within the first two years after the index diagnosis. Compared to NPD, PD was associated with an overall two-fold increased risk of suicide (adjusted hazard ratio, (aHR) 2.19, 95% confidence interval (CI) 1.95, 2.46), after adjusting for psychiatric comorbidities. In PD, the highest relative risks were for impact-related suicides (aHR 3.03, 95%CI 2.23, 4.13) and for suffocation-related suicides (aHR 2.72, 95%CI 2.23, 3.30), whereas the lowest relative risk was for intentional poisonings (aHR 1.66, 95%CI 1.37, 2.02).
ConclusionsPsychotic symptoms increased the risk of suicide 2-fold of the risk that was associated with severe depression, after controlling for comorbid psychiatric disorders. The severity of suicidal ideation may be higher in PD than in NPD, which then leads to more lethal methods of self-harm.

Introduction
Due to its relatively high prevalence and recurrent nature, depression causes a major burden on healthcare systems and societies.
ObjectivesTo investigate healthcare resource utilization and costs associated with treatment-resistant depression (TRD) compared with non-TRD depression in Finland.
MethodsOf all patients aged 16-65 years and diagnosed with depression in Finland during 2004-2016, persons with TRD (N=15 405) were identified from nationwide registers and matched 1:1 with comparison persons with depression but no TRD. TRD was defined as initiation of a third treatment trial after having failed two pharmacological treatment trials. Follow-up period covered five years after TRD or corresponding matching data (until end of 2018). Healthcare resource utilization was studied with negative binomial regression and average excess costs of TRD with generalized estimating equations, by adjusting for baseline costs, comorbidity and baseline severity of depression.
ResultsPersons with TRD (mean age 38.7, SD 13.1, 60.0% women) had more healthcare utilization and work disability (sick leaves and disability pensions), adjusted incidence rate ratio for work disability days was 1.72 (95% CI 1.64-1.80). This resulted in higher total costs for persons with TRD, adjusted mean difference 7572 (95% CI 7215-7929) EUR per patient per year, higher productivity losses (due to sick leaves and disability pensions, mean difference 5296, 95% CI 5042-5550) and direct healthcare costs (2002, 95% CI 1853-2151) compared with non-TRD patients. Mean difference was highest during the first year after TRD (total costs difference 11760, 95% CI 11314-12206).
ConclusionsTreatment-resistant depression is associated with a significant cost burden.

Background
Substance-induced psychosis (SIP) is a serious condition and may predispose for schizophrenia. We know too little about SIP incidence over time and across countries, including substance-specific SIPs. We estimated annual incidence rate of SIP in Denmark, Norway, and Sweden according to substance, age, gender, and socioeconomic background.
MethodsData were drawn from registries covering the whole adult population in the countries. Annual incidence rate per 100 000 persons of SIPs was estimated for Denmark and Sweden from 2000 to 2016 and for Norway from 2010 to 2015.
ResultsThe annual incidence rate of any SIP fluctuated between 9.3 and 14.1. The most commonly occurring SIPs were those induced by alcohol, cannabis, amphetamines, and multiple substances. There was a steady decrease in the incidence rate of alcohol-induced psychosis from the first to the last year of the observation period in Denmark (from 4.9 to 1.5) and Sweden (from 4.5 to 2.2). The incidence rate of cannabis-induced psychosis increased in all countries, from 2.6 to 5.6 in Denmark, from 0.8 to 2.7 in Sweden, and from 1.8 to 3.0 in Norway. Median age of any SIP decreased in Denmark (from 36 to 29 years) and Sweden (from 41 to 31 years). Incidence rates were higher in men and in individuals on disability pension, and increased more among those with high parental education.
ConclusionsWe found similar and stable incidence rates of any SIP in all Scandinavian countries through the observation period. The incidence of alcohol-induced psychosis decreased. The incidence of cannabis-induced psychosis increased.

Aims
Labour market marginalisation (LMM), i.e. severe problems in finding and keeping a job, is common among young adults with attention-deficit/hyperactivity disorder (ADHD). This study aimed to disentangle the extent of LMM as well as the heterogeneity in patterns of LMM among young adults with ADHD and what characterises those belonging to these distinct trajectories of LMM.
MethodsThis population-based register study investigated all 6287 young adults, aged 22–29 years, who had their first primary or secondary diagnosis of ADHD in Sweden between 2006 and 2011. Group-based trajectory (GBT) models were used to estimate trajectories of LMM, conceptualised as both unemployment and work disability, 3 years before and 5 years after the year of an incident diagnosis of ADHD. Odds ratios (ORs) with 95% confidence intervals (CIs) for the association between individual characteristics and the trajectory groups of LMM were estimated by multinomial logistic regression.
ResultsSix distinct trajectories of LMM were found: ‘increasing high’ (21% belonged to this trajectory group) with high levels of LMM throughout the study period, ‘rapidly increasing’ (19%), ‘moderately increasing’ (21%), ‘constant low’ (12%) with low levels of LMM throughout the study period, ‘moderately decreasing’ (14%) and finally ‘fluctuating’ (13%), following a reversed u-shaped curve. Individuals with the following characteristics had an increased probability of belonging to trajectory groups of increasing LMM: low educational level (moderately increasing: OR: 1.4; CI: 1.2–1.8, rapidly increasing: OR: 1.7; CI: 1.3–2.1, increasing high: OR: 2.9; CI: 2.3–3.6), single parents (moderately increasing: OR: 1.6; CI: 1.1–2.4, rapidly increasing: OR: 2.0; CI: 1.3–3.0), those born outside the European Union/the Nordic countries (rapidly increasing: OR: 1.7; CI: 1.1–2.5, increasing high: OR: 2.1; CI: 1.4–3.1), persons living in small cities/villages (moderately increasing: OR: 2.4; CI: 1.9–3.0, rapidly increasing: OR: 2.1; CI: 1.6–2.7, increasing high: OR: 2.6; CI: 2.0–3.3) and those with comorbid mental disorders, most pronounced regarding schizophrenia/psychoses (rapidly increasing: OR: 6.7; CI: 2.9–19.5, increasing high: OR: 12.8; CI: 5.5–37.0), autism spectrum disorders (rapidly increasing: OR: 4.6; CI: 3.1–7.1, increasing high: OR: 9.6; CI: 6.5–14.6), anxiety/stress-related disorders (moderately increasing: OR: 1.3; CI: 1.1–1.7, rapidly increasing: OR: 2.0; CI: 1.6–2.5, increasing high: OR: 1.8; CI: 1.5–2.3) and depression/bipolar disorder (moderately increasing: OR: 1.3; CI: 1.0–1.6, rapidly increasing: OR: 1.7; CI: 1.4–2.2, increasing high: OR: 1.5; CI: 1.2–1.9).
ConclusionsAbout 61% of young adults were characterised by increasing LMM after a diagnosis of ADHD. To avoid marginalisation, attention should especially be given to young adults diagnosed with ADHD with a low educational level, that are single parents and who are living outside big cities. Also, young adults with comorbid mental disorders should be monitored for LMM early in working life.

Introduction
Workplace violence (WPV) is a worldwide health problem with major individual and societal consequences. Previously identified predictors of WPV include working in psychiatry and work stress.
ObjectivesTo investigate WPV trends during Norwegian doctors’ careers and assess individual long-term predictors in a longitudinal study.
MethodsTwo nationwide medical student cohorts (n=1052) who graduated 6 years apart were surveyed at graduation (T1, 1993/94 and 1999) and 4 (T2), 10 (T3), 15 (T4) and 20 (T5) years after graduation (Figure 1). WPV was measured as multiple threats or acts of violence experienced at least twice. Individual predictors were obtained at T1 and work-related factors at T2–T5. WPV was analysed using repeated measures (Generalized Estimating Equations).
ResultsThe prevalence of multiple threats and acts of violence declined at T2–T5 (p<0.001). Adjusted predictors of threats were male gender (odds ratio, OR 2.76, [95% confidence interval] 1.73–4.40; p<0.001), vulnerability traits (OR 0.90, [0.82–0.99]; p=0.031), older cohort (OR 1.63,[1.04–2.58], p=0.035) and working in psychiatry (OR 7.50, [4.42–12.71]; p<0.001). Adjusted predictors of acts were male gender (OR 3.37, [1.45–7.84]; p=0.005), older cohort (OR 6.08, [1.68–21.97]; p=0.006) and working in psychiatry (OR 12.34, [5.40–28.23]; p<0.001).
ConclusionsHigher rates of multiple threats and acts of violence were observed during early medical careers, with men at higher risk. Low levels of vulnerability traits (neuroticism) predicted independently the experience of violent threats. A cohort effect indicated a reduction in WPV (both threats and acts) in the younger cohort.

Introduction
There is a lack of knowledge on utilized pharmacotherapies for treatment resistant depression (TRD).
ObjectivesTo investigate the courses of treatment of TRD.
MethodsAll patients aged 16-65 years and diagnosed with depression in Finland during 2004-2016 were included (identified from nationwide registers for inpatient and specialized outpatient care, sick leaves and disability pensions). New antidepressant users were identified with six-month washout period and followed up for two years to observe the possible emergence of TRD, which was defined as initiation of a third treatment after having two failed pharmacological treatments with adequate duration. Pharmacological treatments were analyzed using PRE2DUP-method.
ResultsDuring follow-up, 177,144 persons had their first registered depression (mean age:39.5, 62.5% women). Of them, 10.9% (N=19,322) met TRD criteria. Among the TRD patients, most common first and second lines antidepressants were as follows: SSRIs (44.6%), mirtazapine (19.0%) and SNRIs (16.5%). As the third line of treatment, 44.2% of TRD patients had antidepressant monotherapy, 32.1% a combination of ≥2 antidepressants, 15.8% antipsychotic or mood stabilizer augmentation and an antidepressant, 4.9% both combination of antidepressants and an augmentation with a mood stabilizer or antipsychotic, 2.7% antipsychotic or mood stabilizer monotherapy and 0.3% ECT monotherapy. Of TRD patients, 36.2% (N=6985) progressed to the fourth line of treatment and most common treatments were antidepressant monotherapy (37.5%), antidepressant combinations (30.8%) and augmentation (20.3%).
ConclusionsAlthough antidepressant combination and augmentation strategies became more frequent, antidepressant monotherapies were still the most common third and fourth lines of depression treatment.

Introduction
Schizophrenia is highly comorbid with substance use disorders (SUD), which may negatively impact the course of illness. However, large studies exploring the best lines of treatment for this combination are lacking.
ObjectivesWe investigated what are the most effective antipsychotics for patients with schizophrenia in preventing the development of substance use disorders and preventing hospitalizations in patients already having substance use disorder.
MethodsWe used two independent national cohort registries including all patient with schizophrenia aged under 46 years. Participants were followed during 22 (1996–2017, Finland) and 11 years (2006–2016, Sweden). We studied risk of rehospitalization, and risk of developing an SUD when using vs. not using antipsychotics, using Cox proportional hazards regression analysis models.
Results45,476 patients with schizophrenia were identified (30,860 in Finland; 14,616 in Sweden). For patients without SUD, clozapine and antipsychotic polytherapy were associated with the lowest risks of developing SUD in both countries. For patients with co-existing SUD, the risk of hospitalization was the lowest during clozapine, polytherapy and long-acting injectable use.
ConclusionsIn patients with schizophrenia and comorbid SUD, antipsychotic medications were effective in preventing relapses. In those without an SUD, antipsychotic use was associated with a markedly reduced risk of developing an initial SUD. Clozapine and long-acting injectables should be considered treatments of choice in patients with schizophrenia and SUD, or at risk of developing co-morbid SUD.

Introduction
Schizophrenia is highly comorbid with substance use disorders (SUD) but large epidemiological cohorts exploring the prevalence and prognostic significance of SUD are lacking.
ObjectivesTo investigate the prevalence of SUD in patients with schizophrenia in Finland and Sweden, and the effect of these co-occurring disorders on risks of psychiatric hospitalization and mortality.
Methods45,476 individuals with schizophrenia from two independent national cohort studies, aged <46 years at cohort entry, were followed during 22 (1996-2017, Finland) and 11 years (2006-2016, Sweden). We first assessed SUD prevalence (excluding smoking). Then we performed Cox regression on risk of psychiatric hospitalization and mortality in patients with schizohrenia and SUD compared with those without SUD.
ResultsThe prevalence of SUD in specialized healthcare ranged from 26% (Finland) to 31% (Sweden). Multiple drug use and alcohol use disorders were the most prevalent SUD, followed by cannabis use disorders. Any SUD comorbidity, and particularly multiple drug use and alcohol use, were associated with 50% to 100% increases in hospitalization and mortality compared to individuals without SUD. Elevated mortality risks were observed especially for deaths due to suicide and other external causes. All results were similar across countries.
ConclusionsCo-occurring SUD, and particularly alcohol and multiple drug use, are associated with high rates of hospitalization and mortality in patients with schizophrenia. Preventive interventions should prioritize detection and tailored treatments for these co-morbidities, which often remain underdiagnosed and untreated.

Background:
Studies investigating psychiatric disorders as Alzheimer's disease (AD) risk factors have yielded heterogeneous findings. Differences in time windows between the exposure and outcome could be one explanation. We examined whether (1) mental and behavioral disorders in general or (2) specific mental and behavioral disorder categories increase the risk of AD and (3) how the width of the time window between the exposure and outcome affects the results.
Methods:A nationwide nested case-control study of all Finnish clinically verified AD cases, alive in 2005 and their age, sex and region of residence matched controls (n of case-control pairs 27,948). History of hospital-treated mental and behavioral disorders was available since 1972.
Results:Altogether 6.9% (n = 1932) of the AD cases and 6.4% (n = 1784) of controls had a history of any mental and behavioral disorder. Having any mental and behavioral disorder (adjusted OR = 1.07, 95% CI = 1.00–1.16) or depression/other mood disorder (adjusted OR = 1.17, 95% CI = 1.05–1.30) were associated with higher risk of AD with 5-year time window but not with 10-year time window (adjusted OR, 95% CI 0.99, 0.91–1.08 for any disorder and 1.08, 0.96–1.23 for depression).
Conclusions:The associations between mental and behavioral disorders and AD were modest and dependent on the time window. Therefore, some of the disorders may represent misdiagnosed prodromal symptoms of AD, which underlines the importance of proper differential diagnostics among older persons. These findings also highlight the importance of appropriate time window in psychiatric and neuroepidemiology research.

Introduction
The clinical distinction between schizophrenia and affective psychoses is often not clear-cut, and very little is known about the effectiveness of treatments among patients having both schizophrenia and affective symptoms.
ObjectivesTo study the comparative real-world effectiveness of antipsychotic treatments among patients having schizophrenia and affective symptoms.
MethodsWe studied the risk of all-cause rehospitalization during use of specific antipsychotics during 1996–2012 among all patients who had been previously hospitalized with both schizophrenia and mood disorder diagnoses in Finland since 1987 (n = 28,015). We linked nation-wide databases on hospitalization, mortality, and filled prescriptions. The primary analysis was within-individual analysis, in which each individual was used as his/her own control to eliminate selection bias. The effect of concomitant psychotropic medications, and the temporal orders of exposure and non-exposure periods were adjusted.
ResultsWhen 22 specific antipsychotic treatments were compared with the most frequently used antipsychotic quetiapine, the lowest rehospitalization risks were observed during the treatment periods of olanzapine long-acting injection (LAI) (HR: 0.52; 95% CI: 0.34–0.80), risperidone LAI (0.67; 0.56–0.81), and clozapine (0.68; 0.63–0.74). The worst outcome was observed for periciazine (1.19; 0.96–1.48) and no antipsychotic use (1.09; 1.04–1.13).
ConclusionsOlanzapine LAI, risperidone LAI, and clozapine use are associated with the lowest risk of rehospitalization among patients with schizophrenia and affective symptoms.
