Humor Associated With Positive Outcomes in Individual Psychotherapy.

Considerable anecdotal evidence points to the usefulness of humor in the therapeutic process, but empirical evidence is lacking. The purpose of this study, conducted in Belgium, was to search for an association between humor and therapy outcomes in a population of 110 adult psychotherapy clients who attended at least 10 therapy sessions. Clients and their therapist evaluated the frequency and intensity of humorous events, as well as therapy effectiveness, therapeutic alliance, perceived hope, and pleasure in participating in therapy sessions. A strong positive correlation was observed between humor and therapy effectiveness, from both client (rs=0.40; p<0.001) and therapist perspectives (rs=0.37; p<0.001). The link between humor and therapy effectiveness remained significant in subgroups of clients with more severe illness, although these clients reported less humor in their therapy sessions. Further research is needed to determine whether humor enhances outcomes or whether positive outcomes trigger occurrence of humor.

Efficacy of Heroin-assisted Treatment In Belgium: A Randomised Controlled Trial.

BACKGROUND/AIMS: Heroin-assisted treatment (HAT) can improve the condition of heroin addicts still using street heroin after a methadone treatment. In Belgium, a new trial compared the efficacy of a HAT to existing methadone maintenance treatment. METHODS: In this randomised controlled trial, HAT was limited to 12 months. Participants were assessed every 3 months. They were responders if they showed improvement on the level of street heroin use, health or criminal involvement. RESULTS: 74 participants were randomised in the trial. The experimental group (n = 36) counted 30% of responders more than the control group (n = 38) at each assessment point (p < 0.05), except at 12 months where the difference (11%) was no longer significant (p = 0.35). Still, after 12 months, participants in the experimental group reported significantly greater improvements (p < 0.05) than the control group on the level of street heroin use and on the level of physical and mental health. Both groups reported significantly less criminal acts after 12 months (p < 0.001), but with no significant difference between the groups. CONCLUSIONS: This trial confirms the short-term efficacy of HAT for severe heroin addicts, who already failed methadone treatment.

The downward spiral of mental disorders and educational attainment: a systematic review on early school leaving.

BACKGROUND: Most psychiatric disorders present symptom patterns that cause severe impairment on the emotional, cognitive and social level. Thus, adolescents who suffer from a mental disorder risk finding themselves in a downward spiral caused by the reciprocal association of psychological symptoms and negative school experiences that may culminate in early school leaving. In addition to previous collective work that mainly focused on school refusing behaviour among children and was presented as an expert's opinion, the following systematic review fills the knowledge gap by providing a structured overview of the bidirectional association between mental health and secondary school dropout based on a sound methodology and with a particular focus on mediating factors. METHODS: Four electronic databases were searched from January 1990 until June 2014. Selected references were assessed for study details, main results, mediating factors and methodological limitations. Standardized risk of bias assessment was conducted. RESULTS: Mood and anxiety disorders seemed to have a less consequential direct effect on early school leaving than substance use and disruptive behaviour disorders. The association between externalizing disorders and educational attainment was even stronger when the disorder occurred early in life. On the other hand, internalizing disorders were reported to develop as a consequence of school dropout. Only few studies had addressed gender differences, with discrepant results. Socio-economic background, academic achievement and family support were identified as significant mediating factors of the association between mental disorders and subsequent educational attainment. CONCLUSIONS: Findings suggested a strong association between mental health and education, in both directions. However, most studies focused on mediating factors that could not be targeted by intervention programs.

Prevalence and clinical characteristics of remission during treatment in generalized anxiety.

OBJECTIVE: Although the remission criteria for generalized anxiety are well defined, there is not much data available on the point prevalence of remission. The Measuring Impact of Remission in Anxiety Disorders in Belgium (MIRABEL) study is a naturalistic study designed to document the point prevalence of remission in patients treated for general anxiety and potential factors affecting this prevalence. METHODS: The study population consisted of 618 adult outpatients being treated for generalized anxiety. The sample is defined by the key symptoms of generalized anxiety disorder rather than by fulfilling the exact DSM-IV-TR diagnostic criteria. Remission was defined as a Hamilton Anxiety Scale (HAM-A) score of less than or equal to 7. To reduce the interrater reliability, the HAM-A was assessed by the attending physicians who had no specific training. Factors investigated as possibly related to remission included sociodemographic, disease and treatment characteristics. RESULTS: The point prevalence of remission in the study population was estimated at 13.3%. Remission prevalence varied with occupational status and severity of the current anxiety episode. Remission prevalence was lower in the presence of comorbidity and was proportional to the number of comorbid symptoms. Remitters took fewer medications but were treated longer. Remission prevalence was higher in patients who were taking antidepressants, but was lower in patients who were taking sedatives. CONCLUSIONS: These findings underline the poor prognosis of generalized anxiety.

Depression alters "top-down" visual attention: a dynamic causal modeling comparison between depressed and healthy subjects.

Using functional magnetic resonance imaging (fMRI), we recently demonstrated that nonmedicated patients with a first episode of unipolar major depression (MDD) compared to matched controls exhibited an abnormal neural filtering of irrelevant visual information (Desseilles et al., 2009). During scanning, subjects performed a visual attention task imposing two different levels of attentional load at fixation (low or high), while task-irrelevant colored stimuli were presented in the periphery. In the present study, we focused on the visuo-attentional system and used "Dynamic Causal Modeling" (DCM) on the same dataset to assess how attention influences a network of three dynamically-interconnected brain regions (visual areas V1 and V4, and intraparietal sulcus (P), differentially in MDD patients and healthy controls. Bayesian model selection (BMS) and model space partitioning (MSP) were used to determine the best model in each population. The best model for the controls revealed that the increase of parietal activity by high attention load was selectively associated with a negative modulation of P on V4, consistent with high attention reducing the processing of irrelevant colored peripheral stimuli. The best model accounting for the data from the MDD patients showed that both low and high attention levels exerted modulatory effects on P. The present results document abnormal effective connectivity across visuo-attentional networks in MDD, which likely contributes to deficient attentional filtering of information.

Do general practitioners and psychiatrists agree about defining cure from depression? The DEsCRIBE™ survey.

BACKGROUND: This study aimed to document the outcome dimensions that physicians see as important in defining cure from depression. The study also aimed to analyse physicians' attitudes about depression and to find out whether they affect their prescribing practices and/or the outcome dimensions that they view as important in defining cure. METHODS: A 51-item questionnaire based on six validated scales was used to rate the importance of several depression outcome dimensions. Physicians' attitudes about depression were also assessed using the Depression Attitude Scale. Overall, 369 Belgian physicians (264 general practitioners [GPs]; 105 psychiatrists) participated in the DEsCRIBE™ survey. RESULTS: GPs and psychiatrists strongly agreed that functioning and depressive symptomatology were most important in defining cure; anxious and somatic symptomatology was least important. GPs and psychiatrists differed in their attitudes about depression (p <0.001). Logistic regression revealed that the attitudes of GPs - but not psychiatrists - were significantly associated with their rates of antidepressant prescription (p < 0.001) and that certain attitudes predicted which outcome dimensions were seen as important in defining cure. CONCLUSIONS: Belgian GPs and psychiatrists strongly agreed on which criteria were important in defining cure from depression but differed in their attitudes about depression. The outcome dimensions that were considered important in defining cure were influenced by physicians' attitudes - this was more pronounced in GPs than in psychiatrists.

Psychosocial risk and protective factors of secondary school dropout in Luxembourg: the protocol of an exploratory case-control study.

BACKGROUND: In Luxembourg, the extensive phenomenon of school dropout is a prime policy concern in the light of individual, social and economic consequences. Although the authorities report an overall decrease of the national dropout rate, the proportion of early school leavers who remain without any specific occupation is still alarming. Therefore, this study intends a shift of focus from system-inherent to individual factors, including mental health and family correlates, to provide a more comprehensive analysis of the dropout phenomenon. METHODS/DESIGN: The objectives of this study are to investigate the type and prevalence of psychiatric disorders among school dropouts and to compare the findings with those by a matched control group of regularly enrolled students. Furthermore, family variables and socioeconomic status will be analysed, as they are factors likely to interfere with both educational attainment and mental health. A trained psychologist will use structured interviews and self-report forms to investigate for mental health issues, information on schooling, socioeconomic situation and family life. Controls will be matched for gender, age, school type and educational grade. DISCUSSION: As school dropouts face a serious risk of long term professional and social marginalization, there is an evident need for action. Identifying psychosocial risk and protective factors of school dropout will deliver solid insight on how to conceive public health strategies for young people who may need a more customized support to carry out their academic potential.

Abnormal neural filtering of irrelevant visual information in depression.

The pathophysiology of major depressive disorder (MDD) includes both affective and cognitive dysfunctions. We aimed to clarify how regions regulating affective processing interact with those involved in attention, and how such interaction impacts perceptual processing within sensory cortices. Based on previous work showing that top-down influences from attention can determine the processing of external inputs within early sensory cortices, we tested with functional magnetic resonance imaging (fMRI) whether MDD alters attentional ("top-down") effects on the neural filtering of irrelevant, nonemotional visual stimuli. The present fMRI study was conducted in 14 nonmedicated patients with a first episode of unipolar MDD and 14 matched controls. During scanning, subjects performed two tasks imposing two different levels of attentional load at fixation (easy or difficult), while irrelevant colored stimuli were presented in the periphery. Analyses of fMRI data revealed that MDD patients show (1) an abnormal filtering of irrelevant information in visual cortex, (2) an altered functional connectivity between frontoparietal networks and visual cortices, and (3) a hyperactivity in subgenual cingulate/medial orbitofrontal cortex that was modulated by attentional load. These results demonstrate that biological abnormalities contribute to the cognitive deficits seen in major depression, and clarify how neural networks implicated in mood regulation influence executive control and perceptual processes. These findings not only improve our understanding of the pathophysiological mechanisms underlying cognitive dysfunctions in MDD, but also shed new light on the interaction between cognition and mood regulation.

Duloxetine in major depressed patients resistant to SSRIs and/or venlafaxine.

Several acute depression trials suggest that only 35% of the patients achieve remission state with antidepressant monotherapy. An increasing body of evidence is emerging suggesting that multi-action antidepressants might be more effective in treatment-resistant depressed patients than single-action agents. In this context, the purpose of the study was to assess the effectiveness of duloxetine in treatment-resistant major depressed outpatients. We performed a retrospective study assessing the efficacy of duloxetine in major depressed outpatients who did not achieve full symptom remission (CGI-S (severity) >=3) after treatment of adequate dose and duration (more than 8 weeks) with at least either one SSRI or the SNRI venlafaxine. We excluded patients with a severe medical illness and a personality disorder. CGI-S was used as a measure of symptom severity and administered before the prescription of duloxetine and 6 weeks later. The sample included 29 patients (9 M, 20 F). We observed a very significant decrease in CGI-S scores (4.86 ± 0.51 to 2.17 ± 1.44, p<0.0001) after treatment with duloxetine (dose between 60 and 120 mg). Remission was achieved in 48% of the patients. The tolerance was excellent. This study suggests the potential interest of duloxetine in some treatment-resistant depressed patients.

Electroconvulsive therapy for depression in a patient with an intracranial arachnoid cyst.

Electroconvulsive therapy (ECT) has been frequently considered relatively contraindicated in patients with space-occupying lesions in the brain. After the 7 cases available in the literature, we describe the safe use of ECT in a depressive patient with arachnoid cyst. We provide a comprehensive review on this clinical association, and we conclude that even if the few data available are reassuring, careful neurological evaluation before the ECT treatment is indicated.

Vasopressin-neurophysin and DST in major depression: relationship with suicidal behavior.

The purpose of the present study was to assess if AVP-neurophysin is associated with hypercortisolemia and suicidal behaviour in depressed patients. The study included 28 patients subgrouped into suicide attempters (n=13) and nonattempters (n=15). We assessed basal AVP-neurophysins concentrations and post-dexamethasone (DST) cortisol levels. Concentrations of AVP-neurophysins did not differ between DST suppressors and nonsuppressors: 0.29+/-0.13 ng/ml vs 0.36+/-0.21 ng/ml, (F=1.1, df=1, 27, p=0.30). Suicide attempters did not differ from nonattempters for AVP-neurophysins levels. Our results fail to support a role of AVP in the early cortisol escape.

Socioeconomic correlates of generalized anxiety disorder and major depression in primary care: the GADIS II study (Generalized Anxiety and Depression Impact Survey II).

A previous Generalized Anxiety Disorder Impact Survey (GADIS I) performed on 15,399 Belgian patients consulting their primary care physicians, revealed high prevalences of generalized anxiety disorder (GAD) and major depression (MD) with important regional differences. The objective of this study (GADIS II) was to replicate previous findings and to evaluate the role of socioeconomic factors in the diagnoses of GAD and MD. A large-scale cross-sectional survey was conducted in a random sample of 377 general practitioners distributed geographically over Belgium and Luxemburg. Each physician was asked to screen 40 consecutive patients at predefined time periods for the presence of GAD and MD using sections of the Mini International Neuropsychiatric Interview (MINI). Socioeconomic parameters were collected. The level of impairment was assessed using the Sheehan Disability Scale. In a sample of 13,699 patients, point prevalences of GAD and of MD were found to be 13.4 and 11.0%, respectively. Overall, 17.8% of the population was positive for GAD and/or MD. Both disorders were significantly more frequent in women than in men. Marked regional differences were observed with prevalences for GAD and/or MD of 24.2% in Brussels, 22.7% in Wallonia, 13.6% in Luxemburg and 12.9% in Flanders. Several socioeconomic factors were significantly associated with positive diagnoses: living alone, a low level of education and unemployment. However, regional differences remained significant even after controlling for socioeconomic factors. The study confirms the high prevalence of GAD and MD in primary care and the role of several socioeconomic and regional factors in the illnesses.

The short allele of the serotonin transporter promoter polymorphism influences relapse in alcohol dependence.

AIMS: The short (S) allele of the serotonin transporter gene promoter polymorphism (5-HTTLPR) contributes to the risk of alcohol dependence and co-occurring clinical features. We studied the putative link between this allele and relapse. METHODS: 48 alcohol-dependent male patients were recruited and genotyped for the 5-HTTLPR. Relapse to alcohol drinking was monitored during 3 months after standardized withdrawal. RESULTS: The S allele was significantly associated with relapse (p = 0.008) while no other factor that was measured played a significant role. CONCLUSIONS: The S allele of the 5-HTTLPR polymorphism may influence the risk of relapse in abstinent alcohol-dependent patients, possibly through intermediate phenotypes.

Nitrous oxide and xenon prevent amphetamine-induced carrier-mediated dopamine release in a memantine-like fashion and protect against behavioral sensitization.

BACKGROUND: Amphetamine administration induces stimulation-independent dopamine release in the nucleus accumbens (NAcc) through reverse dopamine transport, a critical neurochemical event involved in its psychostimulant action, and furthermore decreases stimulation-dependent vesicular dopamine release. These effects may involve possible indirect glutamatergic mechanisms. METHODS: We investigated the effects of nitrous oxide and xenon, which possess antagonistic action at the N-methyl-D-aspartate (NMDA) receptor, on brain slices ex vivo on amphetamine-induced changes in carrier-mediated and KCl-evoked dopamine release in the NAcc, and in vivo on amphetamine-induced locomotor sensitization. RESULTS: Like the low-affinity NMDA receptor antagonist memantine, but not the prototypical compound MK-801, nitrous oxide and xenon at appropriate concentrations blocked both the increase in carrier-mediated dopamine release and locomotor sensitization produced by amphetamine. CONCLUSIONS: In contrast to what has generally been found using prototypical NMDA receptor antagonists, these data regarding the effect of memantine, nitrous oxide, and xenon support the hypothesis that activation of certain NMDA receptors (possibly those containing the NR1a/NR2D subunit) in the NAcc is involved in the amphetamine-induced increase in carrier-mediated dopamine release and the development of behavioral sensitization to amphetamine. Nitrous oxide, xenon, and memantine may be of therapeutic interest for treating drug dependence.

Loss of treatment benefit when heroin-assisted treatment is stopped after 12 months.

PURPOSE: In 2013, during a recent heroin-assisted treatment trial, participants in heroin-assisted treatment (HAT) decreased significantly more their street heroin use than participants in oral methadone treatment. After the trial, HAT was discontinued. To examine whether the treatment benefits were sustained three months after the trial, the use of street heroin by the participants was analyzed in a follow-up study. RESULTS: At the follow-up assessment, street heroin use increased in the experimental group. The two groups no longer showed a significant difference (p=0.55) in the level of street heroin use. CONCLUSION: A predetermined and forced end of HAT was followed by a significant increase in the level of street level use.

5-Hydroxytryptamine 1A receptors, major depression, and suicidal behavior.

BACKGROUND: Several lines of evidence suggest a clear relationship between serotonin (5-hydroxytryptamine, 5-HT) hypoactivity and suicidal behavior across several psychiatric diagnoses. Few data are available, however, regarding the possible specific role of 5-HT1A receptors in the biology of suicidality. Therefore, the aim of our study was to use a neuroendocrine strategy to test the hypothesis of a role for 5-HT1A receptors in the biology of suicidal behavior. METHODS: Hormonal (adrenocorticotropic hormone [ACTH], cortisol, prolactin [PRL]) and temperature responses after administration of flesinoxan, a highly potent and selective 5-HT1A receptor full agonist, were assessed in 40 inpatients with major depression, divided into two subgroups (20 suicide attempters and 20 nonattempters), compared with 20 normal control subjects matched for gender and age. RESULTS: Compared with nonattempters, suicide attempters exhibited significantly lower PRL (p = .01), cortisol (p = .014), and temperature (p = .0002) responses. Prolactin (p = .007), cortisol (p = .04), and temperature (p = .00003) responses were also decreased in suicide attempters compared with normal control subjects. In contrast, we did not observe any significant differences in hormonal or temperature responses to flesinoxan between depressed patients without a history of suicide attempt and normal control subjects. CONCLUSIONS: The present study tends to confirm the role of 5-HT and more specifically 5-HT1A receptors in the biology of suicidal behavior in major depression.

Prevalence and impact of generalized anxiety disorder and major depression in primary care in Belgium and Luxemburg: the GADIS study.

PURPOSE: GADIS aims at determining the prevalence of generalized anxiety disorder (GAD) and major depression (MD) in primary care and their impact on the patient's functioning in Belgium and Luxemburg. METHOD: A large scale screening program was conducted at the consultation of general practitioners to detect patients with GAD and MD according to DSM-IV criteria. We collected additional data regarding the use of hypnotic, tranquilizer, antidepressant and analgesic medications. Impact on the patient was assessed with the Sheehan disability scale. RESULTS: Three hundred GP's in Belgium and Luxemburg were asked to screen 50 consecutive patients. Of the 13,677 analyzed patients, 8.3% were diagnosed to have GAD and 6.3% MD. Comorbidity was observed in 4.2% of patients. The prevalence was much higher in the French-speaking part of Belgium. GAD and MD were associated with impairment in social, familial and professional functioning. Only a minority of patients with GAD and/or MD was treated with an antidepressant and almost half of subjects with GAD and/or MD were treated with a tranquilizer. CONCLUSION: Prevalence rates of GAD and MD in primary care in Belgium are comparable to other countries. GAD and MD are disabling conditions. Antidepressants are still used only in a minority of subjects with GAD and/or MD in primary care in Belgium and Luxemburg. The prevalence of GAD and MD appears to be much higher in French-speaking parts of Belgium.

What is important in being cured from: does discordance between physicians and patients matter? (2).

AIMS: The influence of discordance in what is important in being cured from depression on clinical outcome at 6 months, assessed with a divergence index. METHODS: 304 outpatients treated for depression by general practitioners or by psychiatrists and completing a 6-month treatment period: a divergence index (divergence between physician and patient view on what is important in being cured from depression) was calculated for each physician-patient pair. The relation between this index and outcome at 6 months was analyzed (including depressive, anxious and somatic symptom severity, positive effect, functional impairment and quality of life (psychological and social relations). RESULTS: Response rates (50% improvement) were 65.9% for depressive symptomatology and 46.2% for anxious symptomatology. The subgroup with a poor physician-patient agreement (highest quartile) on expectations had a worse clinical outcome than the subgroup with an excellent physician-patient agreement (lowest quartile): differences in response rate between these groups ranged from 9% to 27%; this difference reached statistical significance for 3 outcome variables (anxiety, positive effect and social relationships). CONCLUSIONS: The study shows that outcomes with standard antidepressant drugs are still suboptimal and that discordance between what patients׳ and physicians׳ consider important in the definition of cure from depression significantly influences clinical outcomes at 6 months.
