The lifetime prevalence of suicide is around 5% in patients with schizophrenia. Non-adherence to antipsychotic medication is an important risk factor, but prospective studies investigating joint effects of antipsychotic drugs, antidepressants, and benzodiazepines on suicidality are scarce. We aimed to investigate how use and non-use of psychotropic medications are associated with suicidality in schizophrenia.
Methods
An open cohort study followed all patients consecutively admitted to a psychiatric acute unit during a 10-year period with a diagnosis of schizophrenia (n = 696). Cox multiple regression analyses were conducted with use of antipsychotics, antidepressants, and benzodiazepines as time-dependent variables. Adjustments were made for age, gender, depressive mood, agitated behavior, and use of alcohol and illicit substances.
Results
A total of 32 (4.6%) suicide events were registered during follow-up. Of these, 9 (28%) were completed suicides and 23 (72%) were attempted suicides. A total of 59 (8.5%) patients were readmitted with suicidal plans during the follow-up. Compared to non-use, use of antipsychotics was associated with 70% lower risk of attempted or completed suicide (adjusted hazard ratio [AHR] = 0.30, p < 0.01, CI 0.14–0.65) and 69% reduced risk of readmission with suicidal plans (AHR = 0.31, p < 0.01, CI 0.18–0.55). Use of prescribed benzodiazepines was associated with 126% increased risk of readmission with suicidal plans (AHR = 2.26, p = 0.01, CI 1.24–4.13).
Conclusions
Adherence to antipsychotic medication is strongly associated with reduced suicidal risk in schizophrenia. The use of prescribed benzodiazepines was identified as a significant risk factor for being readmitted with suicidal plans.
Individual placement and support (IPS) is an evidence-based practice that helps individuals with mental illness gain and retain employment. IPS was implemented for young adults at a municipality level through a cross-sectoral collaboration between specialist mental healthcare, primary mental healthcare, and the government funded employment service (NAV). We investigated whether IPS implementation had a causal effect on employment outcomes for all young adults in receipt of a temporary health-related rehabilitation (work assessment allowance, WAA) welfare benefit, measured at the societal level compared to municipalities that did not implement IPS.
Method
We used a difference in differences design to estimate the effects of IPS implementation on the outcome of workdays per year using longitudinal registry data. We estimate the average effect of being exposed to IPS implementation during four-years of implementation compared to ten control municipalities without IPS for all WAA recipients.
Results
We found a significant, positive, causal effect on societal level employment outcomes of 5.6 (p = 0.001, 95% CI 2.7–8.4) increased workdays per year per individual, equivalent to 12.7 years of increased work in the municipality where IPS was implemented compared to municipalities without IPS. Three years after initial exposure to IPS implementation individuals worked, on average, 10.5 more days per year equating to 23.8 years of increased work.
Conclusions
Implementing IPS as a cross sectoral collaboration at a municipality level has a significant, positive, causal, societal impact on employment outcomes for all young adults in receipt of a temporary health-related rehabilitation welfare benefit.
There are now hundreds of systematic reviews on attention deficit hyperactivity disorder (ADHD) of variable quality. To help navigate this literature, we have reviewed systematic reviews on any topic on ADHD.
Methods
We searched MEDLINE, PubMed, PsycINFO, Cochrane Library, and Web of Science and performed quality assessment according to the Joanna Briggs Institute Manual for Evidence Synthesis. A total of 231 systematic reviews and meta-analyses met the eligibility criteria.
Results
The prevalence of ADHD was 7.2% for children and adolescents and 2.5% for adults, though with major uncertainty due to methodological variation in the existing literature. There is evidence for both biological and social risk factors for ADHD, but this evidence is mostly correlational rather than causal due to confounding and reverse causality. There is strong evidence for the efficacy of pharmacological treatment on symptom reduction in the short-term, particularly for stimulants. However, there is limited evidence for the efficacy of pharmacotherapy in mitigating adverse life trajectories such as educational attainment, employment, substance abuse, injuries, suicides, crime, and comorbid mental and somatic conditions. Pharmacotherapy is linked with side effects like disturbed sleep, reduced appetite, and increased blood pressure, but less is known about potential adverse effects after long-term use. Evidence of the efficacy of nonpharmacological treatments is mixed.
Conclusions
Despite hundreds of systematic reviews on ADHD, key questions are still unanswered. Evidence gaps remain as to a more accurate prevalence of ADHD, whether documented risk factors are causal, the efficacy of nonpharmacological treatments on any outcomes, and pharmacotherapy in mitigating the adverse outcomes associated with ADHD.
Employment is intrinsic to recovery from mental health conditions, helping people live independently. Systematic reviews indicate supported employment (SE) focused on competitive employment, including individual placement and support (IPS), is effective in helping people with mental health conditions into work. Evidence is limited on cost-effectiveness. We comprehensively reviewed evidence on the economic case for SE/IPS programmes.
Methods
We searched PubMed/MEDLINE, EMBASE, PsycINFO, CINAHL, IBSS, Business Source Complete, and EconLit for economic and return on investment analyses of SE/IPS programmes for mental health conditions. Traditional vocational rehabilitation, sheltered work, and return to work initiatives after sickness absence of less than 1 year were excluded. Studies were independently screened by two reviewers. We assessed quality using the Consolidate Health Economic Evaluation Reporting Standards checklist. The protocol was preregistered with PROSPERO-CRD42020184359.
Results
From 40,015 references, 28 studies examined the economic case for IPS, four IPS augmented by another intervention, and 24 other forms of SE. Studies were very heterogenous, quality was variable. Of 41 studies with quality scores over 50%, 10 reported cost per quality-adjusted life year gained, (8 favourable to SE/IPS), 14 net monetary benefits (12 positive), 5 return on investment (4 positive), and 20 cost per employment outcome (14 favorable, 5 inconclusive, 1 negative). Totally, 24 of these 41 studies had monetary benefits that more than outweighed the additional costs of SE/IPS programmes.
Conclusions
There is a strong economic case for the implementation of SE/IPS programmes. The economic case is conservative as evidence on long-term impacts of programmes is limited.
Economic and technological development has increased the amount, density and complexity of maritime traffic, which has resulted in new challenges. One challenge is conforming to the distinct evasion manoeuvres required by vessels entering into near-collision situations (NCSs). Existing rules are vague and do not precisely dictate which, when and how collision avoidance manoeuvres (CAMs) should be executed. The automatic identification system (AIS) is widely used for vessel monitoring and traffic control. This paper presents an efficient, scalable method for processing large-scale raw AIS data using the closest point of approach (CPA) framework. NCSs are identified to create a database of historical traffic data. Important features describing CAMs are defined, estimated and analysed. Applications on a high-quality real-world data set show promising results for a subset of the identified situations. Future applications may play a significant role in the maritime regulatory framework, navigation protocol compliance evaluation, risk assessment, automatic collision avoidance, and algorithm design and testing for autonomous vessels.
Smoking is reported to be associated with depression and anxiety. The present study (a) examines these associations taking comorbidity into account, (b) investigates possible confounders, (c) examines how former smokers compared to current and never-smokers in terms of anxiety and depression, and if anxiety and depression decline by time since cessation. Participants (66%) aged 20–89 years in a population-based health survey (N = 60,814) were screened employing the HADS. (a) The association with smoking was strongest in comorbid anxiety depression, followed by anxiety, and only marginal in depression. Associations were stronger in females and younger participants. (b) Variables partly accounting for the association comprised somatic symptoms, socio-demographics, alcohol problems, and low physical activity. (c) Anxiety and depression were most common in current smokers, followed by quitters, and then never-smokers. No decline in anxiety or depression was found with time since cessation. Previous studies of associations between depression and smoking might have overestimated the association when ignoring comorbid anxiety.
This study from Norway examines mental health status of women with child sexual abuse (CSA) who formerly had outpatient psychotherapy for anxiety disorders and/or depression. The relative contributions of CSA and other family background risk factors (FBRF) to aspects of mental health status are also explored.
Subjects
At a mean of 5.1 years after outpatient psychotherapy, 56 female outpatients with CSA and 56 without CSA were personally examined by an independent female psychiatrist. Systematic information about current mental health and functioning was collected by structured interview and questionnaires.
Results
Among women with CSA 95% had a mental disorder, 50% had PTSD, and mean global assessment of functioning (GAF) score was 61.8 ± 10.6. In contrast, 70% of women without CSA had a mental disorder, 14% had PTSD, and mean GAF 71.2 + 8.5. GAF and trauma scale scores were mainly determined by CSA, while FBRF mainly influenced the global psychopathology and dissociation scores.
Discussion
We have little knowledge on the mental health status at long-term in women with CSA who had psychotherapy. This study found their mental status to be rather poor, and worse than that of women without CSA who had psychotherapy for the same disorders. From the broad spectrum of mental disorders associated with CSA, this study concerns only women treated as outpatients for anxiety disorders and/or non-psychotic depressions.
Conclusion
Women with CSA showed poor mental health at long-term follow-up after treatment. The fitness of the psychodynamic individual psychotherapy given, or to what extent treatment can remedy the consequences of such childhood adversities, is discussed.
Recently there has been a renewed interest in defining the boundaries and subdomains of the negative syndrome in schizophrenia and new scales have been asked for. Apathy is one of the symptoms in focus. The Apathy Evaluation Scale (AES) with its clinical version (AES-C) is one of the most used scales in an interdisciplinary context, but it has never previously been used in a population with first episode psychosis. The main aims of this study were to examine the psychometric properties of the AES-C and its relationship to the Positive and Negative Syndrome Scale (PANSS).
Methods
A total of 104 patients with first episode psychosis from the ongoing Thematic Organized Psychosis Research (TOP) study were included.
Results
A factor analysis of the AES-C identified three subscales: Apathy, Insight and Social Contacts. Only the Apathy subscale showed satisfactory psychometric properties and showed acceptable convergent and discriminate properties by correlating strongly with the apathy-related items of the PANSS.
Conclusions
This study shows that the AES-C measures more than one dimension. The main factor, the Apathy subscale, can however be used to assess apathy in first episode psychosis patients in the ongoing work of refining the subdomains of the negative syndrome.
Depressive symptoms are associated with higher cancer mortality, whereas anxiety symptoms are associated with lower than expected risk.
Aims
This study aimed to investigate the prospective association between depressive/anxiety symptoms and the extent of disease (EOD) of first cancer at diagnosis.
Method
Prospective population-based study conducted from the second wave of the Nord-Trøndelag Health (HUNT) study. Of 65 000 residents comprehensively interviewed and examined for health status, 407 received first lifetime cancer diagnoses 1–3 years later, ascertained from the Cancer Registry of Norway, and had EOD recorded. Patients with localised disease or regional/distant spread at cancer diagnosis were analysed for earlier depressive/anxiety symptoms ascertained by the Hospital Anxiety and Depression Scale in HUNT.
Results
Beyond-local EOD was present in 59.8% of those with neither anxiety nor depression, in 76.6% of those with depression alone (odds ratio, 2.20; 1.08–4.49), in 39.3% of those with anxiety alone (odds ratio, 0.44; 0.20–0.96) and in 57.7% of those with both anxiety and depression (odds ratio, 0.92; 0.41–2.06). After adjustment for demographic and health status, and cancer type, these associations were marginally stronger, but no longer statistically significant (odds ratios, 2.26; 0.84–6.11; 0.43; 0.15–1.26; and 1.00; 0.98–1.03, respectively).
Conclusions
In people who develop cancer, beyond-local EOD at diagnosis was more common in people with previous depression and less common in people with previous anxiety; however, independence from confounding factors could not be concluded.
Individual placement and support (IPS) is a vocational rehabilitation programme that was developed in the USA to improve employment outcomes for people with severe mental illness. Its ability to be generalised to other countries and its effectiveness in varying economic conditions remains to be ascertained.
Aims
To investigate whether IPS is effective across international settings and in different economic conditions.
Method
A systematic review and meta-analysis of randomised controlled trials comparing IPS with traditional vocational services was undertaken; 17 studies, as well as 2 follow-up studies, were included. Meta-regressions were carried out to examine whether IPS effectiveness varied according to geographic location, unemployment rates or gross domestic product (GDP) growth.
Results
The overall pooled risk ratio for competitive employment using IPS compared with traditional vocational rehabilitation was 2.40 (95% CI 1.99–2.90). Meta-regressions indicated that neither geographic area nor unemployment rates affected the overall effectiveness of IPS. Even when a country's GDP growth was less than 2% IPS was significantly more effective than traditional vocational training, and its benefits remained evident over 2 years.
Conclusions
Individual placement and support is an effective intervention across a variety of settings and economic conditions and is more than twice as likely to lead to competitive employment when compared with traditional vocational rehabilitation.
Across Europe grandparents play very different roles. This paper studies to what extent grandparents' role as providers of child care relates to the country policy context, focusing on public child-care services and parental leave regulation, and to the availability of part-time jobs for women. We also explore whether mothers' needs to combine family and work differently influence the frequency of grandparental child care across countries. The analysis combines micro-data from the Survey of Health, Ageing and Retirement in Europe and macro-indicators from the Multilinks database and Eurostat. We find a clear association between policy context and frequency of grandparental child care. Three models emerge. In countries close to the familialism by default model (i.e. characterised by scarce public child-care services and parental leave), when grandparents provide child care they often do it daily. In countries characterised by defamilialisation and supported familialism policies (with generous public services and parental leave) grandparents take on a marginal role. An intermediate model emerges in countries characterised by a limited offer of child care or parental leave, where grandparental child care complements state support and tends to be offered on a weekly basis. Our analysis corroborates the idea that the highly intensive involvement of grandparents in countries with low availability of part-time jobs for women is influenced by the need (unmet by the welfare) of mothers to combine work and family.
To assess impacts of the nationwide Norwegian School Fruit Scheme (NSFS) using nationally representative data.
Design
The NSFS is organized such that primary-school children (grades 1–7) are randomly assigned to one of three school fruit arrangements: (i) the child receives one free fruit or vegetable per day; (ii) the child is given the option to subscribe to one fruit or vegetable per day at a subsidized price; and (iii) the child attends a school that has no school fruit arrangement.
Setting
Data from an Internet survey are used to compare child and parental fruit and vegetable intakes across the three NSFS groups focusing mainly on groups (i) and (iii). The analysis was conducted using multivariate regression techniques.
Subjects
Parents of primary-school children (n 1423) who report on behalf of themselves and their children.
Results
Children who receive free school fruit eat on average 0·36 more fruit portions daily – or 25·0 % more fruits – than children who attend schools with no fruit arrangement (P < 0·001). Moreover, parents of children who receive free school fruit eat on average 0·19 more fruit portions daily – or 12·5 % more fruits – than parents of children who attend schools with no fruit arrangement (P = 0·040). No significant associations were found between the NSFS and the vegetable intakes of children and their parents.
Conclusions
The study shows, using nationally representative data, that free school fruit is associated with increased child fruit intake and that it may also affect parental fruit intake.
Aims – To illustrate the application of sequence analysis to the study of rare patient behaviour in physician-patient dialogue. The rare behaviour in question here is patients' expression of emotional cues and concerns. We investigate which physician behaviours precede and follow such expressions. Methods – Thirty-five cancer-patient consultations performed by four oncologists (two male and two female) were analysed. The consultations were coded with the Roter Interaction Analysis System (RIAS). Sequence analysis by means of Sequential Data Interchange Standard (SDIS) and the Generalized Sequential Querier (GSEQ) was applied to the coded data. Lag analysis (using RIAS categories) was applied to associate the given behaviour (patient ‘concerns’) with target behaviours (physician utterances). Results – For female physicians the significantly associated behaviour before the patient's expression of concern was reassurance, while male physicians also applied facilitation behaviour. After patients' expression of concern both reassurance and facilitating behaviour were shown by physicians of both genders. Conclusions – Sequence analysis appears to be a clinically meaningful and statistically sound method for analysing rare patient utterances and associated physician behaviour.
Previous studies have suggested that physical activity may have antidepressant and/or anti-anxiety effects.
Aims
To examine the bidirectional relationship between physical activity and common mental disorders and establish the importance of context, type and intensity of activity undertaken.
Method
A clinical examination of 40 401 residents of Norway was undertaken. Participants answered questions relating to the frequency and intensity of both leisure-time and workplace activity. Depression and anxiety were measured using the Hospital Anxiety and Depression Scale (HADS). Biological and social data were also collected.
Results
There was an inverse relationship between the amount of leisure-time physical activity and case-level symptoms of depression. This cross-sectional association was only present with leisure-time (as opposed to workplace) activity and was not dependent on the intensity of activities undertaken. Higher levels of social support and social engagement were important in explaining the relationship between leisure activity and depression. Biological changes such as alterations to parasympathetic vagal tone (resting pulse) and changes to metabolic markers had a less important role.
Conclusions
Individuals who engage in regular leisure-time activity of any intensity are less likely to have symptoms of depression. The context and social benefits of exercise are important in explaining this relationship.
Depression is reported to be associated with increased mortality, although underlying mechanisms are uncertain. Associations between anxiety and mortality are also uncertain.
Aims
To investigate associations between individual and combined anxiety/depression symptom loads (using the Hospital Anxiety and Depression Scale (HADS)) and mortality over a 3–6 year period.
Method
We utilised a unique link between a large population survey (HUNT–2,n = 61 349) and a comprehensive mortality database.
Results
Case-level depression was associated with increased mortality (hazard ratio (HR) = 1.52, 95% CI 1.35–1.72) comparable with that of smoking (HR = 1.59, 95% CI 1.44–1.75), and which was only partly explained by somatic symptoms/conditions. Anxiety comorbid with depression lowered mortality compared with depression alone (anxiety depression interactionP = 0.017). The association between anxiety symptom load and mortality was U-shaped.
Conclusions
Depression as a risk factor for mortality was comparable in strength to smoking. Comorbid anxiety reduced mortality compared with depression alone. The relationship between anxiety symptoms and mortality was more complex with a U-shape and highest mortality in those with the lowest anxiety symptom loads.
