Effectiveness of a brief motivation enhancing intervention on treatment initiation, treatment retention and abstinence: Results from a multi-site cluster-randomized trial.

The aim of this study was to test the effectiveness of a brief motivational enhancing intervention (MEI) as an add-on to supervision-as-usual (SAU) in reducing time to treatment initiation in offenders with substance use disorders (SUDs) under probation supervision. We also tested the effectiveness in enhancing treatment retention and abstinence of primary substance rates. The study was designed as a multi-site, cluster randomized trial (CRT) in six addiction probation offices.

The Predictive Value of Impulsivity and Risk-Taking Measures for Substance Use in Substance Dependent Offenders.

Impulsivity and risk-taking are known to have an important impact on problematic substance use and criminal behavior. This study examined the predictive value of baseline self-report and behavioral impulsivity and risk-taking measures [Delay Discounting Task (DDT), Balloon Analogue Risk Task (BART) and Behavioral Inhibition, Behavioral Activation Scale (BIS/BAS)] in 12-months follow-up substance use outcomes (e.g.

The Role of Motivation in Predicting Addiction Treatment Entry Among Offenders With Substance Use Disorders Under Probation Supervision.

Many offenders with a substance use disorder (SUD) do not enter addiction treatment. The aim of this study was to examine predictors of addiction treatment entry and to get more insight in the predictive value of treatment motivation. A total of 83 male offenders with a SUD under probation supervision in the Netherlands were assessed at the start of probation supervision and at 12-month follow-up.

[This corrects the article DOI: 10.1371/journal.pone.

The use and helpfulness of self-management strategies for depression: The experiences of patients.

Objective: To explore which of 50 self-management strategies are actually used and which are perceived as most helpful by patients in their day-to-day management of depression, in order to empower patients and promote active engagement in their own care.

Methods: Retrospective study using an online self-report survey to assess the use and perceived helpfulness of 50 previously identified self-management strategies in 193 participants who recently recovered from a major depressive episode.

Results: Forty-five of the 50 strategies were used by at least half of all participants and about one third of all participants perceived almost 50% of all strategies as (very) helpful.

The measurement of cognitive reactivity to sad mood in patients remitted from major depressive disorder.

Objectives: Cognitive reactivity (CR) to sad mood is a risk factor for major depressive disorder (MDD). CR is usually measured by assessing change on the Dysfunctional Attitudes Scale (DAS-change) after sad mood-induction. It has, however, been suggested that the versions of the DAS (A/B) are not interchangeable, impacting the reliability and validity of the change score.

Diagnosing ADHD during active substance use: Feasible or flawed?

Background: Attention Deficit Hyperactivity Disorder (ADHD) is highly prevalent in patients with a substance use disorder (SUD). Because of possible problems with validity, diagnostic assessment of ADHD is usually postponed until after a period of abstinence, which may jeopardize adequate and timely treatment. The aim of this study is to investigate how a diagnostic assessment of ADHD in patients who are actively using substances compares to the results of a second assessment after a period of full or partial abstinence.

Advanced Glycation End Products in Recent-Onset Psychosis Indicate Early Onset of Cardiovascular Risk.

Objective: Profoundly increased mortality rates in schizophrenia, largely caused by a higher risk and earlier onset of cardiovascular disease, remain a major challenge. During the human lifespan, advanced glycation end products (AGEs) accumulate, and their concentration is strongly linked to cardiovascular mortality. AGE accumulation can be accelerated by several pathways, including oxidative stress.

Nursing Staff Factors Contributing to Seclusion in Acute Mental Health Care - An Explorative Cohort Study.

Background: Seclusion is a controversial intervention. Efficacy with regard to aggressive behaviour has not been demonstrated, and seclusion is only justified for preventing safety hazards. Previous studies indicate that nursing staff factors may be predictors for seclusion, although methodological issues may have led to equivocal results.

Helpful Factors in the Treatment of Depression from the Patient's, Carer's and Professional's Perspective: A Concept Map Study.

Objective: Depression research has resulted in knowledge about neurobiology, pharmacological strategies and short-term cost-effective treatments. However, more than two-thirds of all depressed patients experience insufficient improvement. Therefore, a better understanding of what patients, carers and professionals perceive as most helpful in the treatment of depression is needed.

The impact of second generation antipsychotics on insight in schizophrenia: Results from 14 randomized, placebo controlled trials.

Despite the negative impact of lack of insight on the prognosis, general functioning and treatment adherence, the effect of antipsychotic medication on insight has been investigated only in small samples and uncontrolled studies. In this study we examine whether previously reported effects of antipsychotics on insight from uncontrolled studies can be confirmed in a database including 14 randomized, double-blind, placebo-controlled trials. The database contained placebo-controlled RCTs of five second-generation antipsychotics (SGAs: olanzapine, paliperidone, quetiapine, risperidone and sertindole) and included a total of 4243 patients with schizophrenia.

Childhood trauma exposure in substance use disorder patients with and without ADHD.

Background: Childhood trauma exposure (CTE) is frequently reported by those with substance use disorders (SUDs). SUDs also frequently co-occur with attention deficit hyperactivity disorder (ADHD).

Objective: To investigate the role of childhood trauma exposure (CTE) in the presence and the persistence of ADHD in treatment seeking SUD patients.

Early Nonresponse in the Antipsychotic Treatment of Acute Mania: A Criterion for Reconsidering Treatment? Results From an Individual Patient Data Meta-Analysis.

Objective: To investigate whether early nonresponse to antipsychotic treatment of acute mania predicts treatment failure and, if so, to establish the best definition or criterion of an early nonresponse.

Data Sources: Short-term efficacy studies assessing antipsychotics that were submitted to the Dutch Medicines Evaluation Board during an 11-year period as part of the marketing authorization application for the indication of acute manic episode of bipolar disorder. Pharmaceutical companies provided their raw patient data, which enabled us to perform an individual patient data meta-analysis.

The effect of childhood trauma and Five-Factor Model personality traits on exposure to adult life events in patients with psychotic disorders.

Introduction: Recent life events are associated with transition to and outcome in psychosis. Childhood trauma and personality characteristics play a role in proneness to adult life events. However, little is known about the relative contribution and interrelatedness of these characteristics in psychotic disorders.

Acceptability of Extended-Release Naltrexone by Heroin-Dependent Patients and Addiction Treatment Providers in the Netherlands.

Background: Extended-release naltrexone (XRNT) was developed to overcome poor treatment compliance with oral naltrexone in alcohol and opioid-dependent patients. XRNT injections are registered in the United States and Russia, but not in The Netherlands. However, XRNT can be obtained for individual patients, but it is expensive and not reimbursed by the health insurance.

Vulnerability for new episodes in recurrent major depressive disorder: protocol for the longitudinal DELTA-neuroimaging cohort study.

Introduction: Major depressive disorder (MDD) is widely prevalent and severely disabling, mainly due to its recurrent nature. A better understanding of the mechanisms underlying MDD-recurrence may help to identify high-risk patients and to improve the preventive treatment they need. MDD-recurrence has been considered from various levels of perspective including symptomatology, affective neuropsychology, brain circuitry and endocrinology/metabolism.

Persistence and Subtype Stability of ADHD Among Substance Use Disorder Treatment Seekers.

To examine ADHD symptom persistence and subtype stability among substance use disorder (SUD) treatment seekers. In all, 1,276 adult SUD treatment seekers were assessed for childhood and adult ADHD using Conners' Adult ADHD Diagnostic Interview for (4th ed.; ; CAADID).

Does Insight Affect the Efficacy of Antipsychotics in Acute Mania?: An Individual Patient Data Regression Meta-Analysis.

Patients having an acute manic episode of bipolar disorder often lack insight into their condition. Because little is known about the possible effect of insight on treatment efficacy, we examined whether insight at the start of treatment affects the efficacy of antipsychotic treatment in patients with acute mania. We used individual patient data from 7 randomized, double-blind, placebo-controlled registration studies of 4 antipsychotics in patients with acute mania (N = 1904).

Cognitive reactivity versus dysfunctional cognitions and the prediction of relapse in recurrent major depressive disorder.

Objective: Major depressive disorder (MDD) is a burdensome disease that has a high risk of relapse/recurrence. Cognitive reactivity appears to be a risk factor for relapse. It remains unclear, however, whether dysfunctional cognitions alone or the reactivity of such cognitions to mild states of sadness (ie, cognitive reactivity) is the crucial factor that increases relapse risk.

Levels of Red Blood Cell Fatty Acids in Patients With Psychosis, Their Unaffected Siblings, and Healthy Controls.

Background: Two recent meta-analyses showed decreased red blood cell (RBC) polyunsaturated fatty acids (FA) in schizophrenia and related disorders. However, both these meta-analyses report considerable heterogeneity, probably related to differences in patient samples between studies. Here, we investigated whether variations in RBC FA are associated with psychosis, and thus may be an intermediate phenotype of the disorder.

Erythrocyte fatty acid profiles and plasma homocysteine, folate and vitamin B6 and B12 in recurrent depression: Implications for co-morbidity with cardiovascular disease.

Oxidative stress induced interactions between fatty acid (FA) and one-carbon metabolism may be involved in co-occurrence of major depressive disorder (MDD) and cardiovascular disease (CVD), which have been scarcely studied together. In 137 recurrent MDD-patients vs. 73 age- and sex-matched healthy controls, we simultaneously measured key components of one-carbon metabolism in plasma (homocysteine, folate, vitamins B6 and B12), and of FA-metabolism in red blood cell membranes [main polyunsaturated fatty acids (PUFAs) eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and arachidonic acid (AA) and structural FA-indices (chain length, unsaturation, peroxidation)].

Potency trends of Δ9-tetrahydrocannabinol, cannabidiol and cannabinol in cannabis in the Netherlands: 2005-15.

Background And Aims: Between 2000 and 2005 the average percentage of Δ(9) -tetrahydrocannabinol (THC) in marijuana as sold in Dutch coffeeshops has increased substantially; the potency of domestic products (Nederwiet and Nederhasj) has particularly increased. In contrast with imported marijuana, Nederwiet hardly contained any cannabidiol (CBD), a cannabinoid that is thought to offset some of the adverse effects of THC. In 2005, the THC content in Nederwiet was significantly lower than in 2004.

Enduring effects of Preventive Cognitive Therapy in adults remitted from recurrent depression: A 10 year follow-up of a randomized controlled trial.

Background: Prevention of recurrence is a challenge in the management of major depressive disorder (MDD). The long-term effects of Preventive Cognitive Therapy (PCT) in preventing recurrence in MDD are not known.

Methods: A RCT comparing the addition of PCT to Treatment As Usual (TAU), versus TAU including patients with recurrent depression who were in remission at entry (N=172).

Predictors of impaired work functioning in employees with major depression in remission.

Objectives: This study aims to (i) assess work functioning in employees returning to work with a major depression in remission, (ii) study the predictors of impaired work functioning.

Methods: Participants diagnosed with major depressive disorder (MDD), on long term sick leave (mean 27 weeks) and treated in a specialized mental healthcare setting, were selected from an intervention study sample. They were eligible for this study if they were remitted from their depression and had returned to work for at least 50% of their contract hours at 18 month follow-up.

Fatty acid metabolism and its longitudinal relationship with the hypothalamic-pituitary-adrenal axis in major depression: Associations with prospective antidepressant response.

Background: Metabolism of dietary fatty acids (FAs), and its relationship with the hypothalamic-pituitary-adrenal (HPA)-axis, have been found to be altered in major depressive disorder (MDD). Moreover, indications exist that these factors are associated with antidepressant-response. If we better understand these associations, we might identify novel targets for add-on therapy to increase antidepressant-response, and/or early indicators to improve response prediction.
