[Barriers in mental health care for asylum seekers]. / Barrières in de ggz voor asielzoekers in hoge-inkomenslanden.

Background  Despite high prevalence of psychopathology, the use of mental health services by asylum seekers seems low. Barriers to care may play an important role in this. Aim  To explore the barriers in mental health care for adult and adolescent asylum seekers and their care providers in high-income countries. Method  A narrative literature review, based on a systematic evaluation of the current scientific literature. Results  In a narrative synthesis of the results, we identified the following six categories of barriers: lack of knowledge of the healthcare system, language barriers, discrepant beliefs and expectations of mental healthcare, lack of trust towards authority, and structural difficulties. Conclusion  Six thematic barriers were retained. Different interventions are possible to address these barriers. Further research into needs and interventions is recommended, with specific attention to the Belgian and Dutch context.

[Psychiatric disorders in adults with Prader-Willi syndrome: a systematic literature review]. / Psychiatrische comorbiditeit bij volwassenen met prader-willisyndroom: systematisch literatuuroverzicht.

BACKGROUND: Prader-Willi syndrome (PWS) is a genetic syndrome characterized by dysmorphic features and endocrine, cognitive and psychiatric problems. Psychiatric problems interfere with the transition from pediatric to adult care. Psychiatric expertise is needed to facilitate this transition. AIM: To provide a literature review on the prevalence and clinical presentation of psychiatric disorders in adults with PWS. METHOD: A systematic literature review following the PRISMA-guidelines. RESULTS: Thirty-three articles were included. Most adults with PWS had a specific behavioral profile with disruptive, autistic and compulsive characteristics. Psychotic symptoms occured in one third of adults with PWS, mostly in patients with maternal uniparental disomy. Mood disorders were present in 10 to 20% of adults with PWS and often accompanied by psychotic features. Studies were limited and heterogeneous in samples and methods. CONCLUSION: There is a broad spectrum of psychiatric symptoms in adults with PWS. The clinical presentation does not fully fit within the DSM categories and shows differences between genetic subgroups. Longitudinal studies assessing the psychiatric symptoms with standardized methods are needed to improve practices on diagnosing, prevention, and treatment.

The longitudinal course of cognitive insight and mood in bipolar disorder.

Cognitive insight or the ability to be self-reflective and to retain from being over-confident in own beliefs is an upcoming topic in research regarding psychiatric disorders. In bipolar disorder investigations are scarce and an important lacuna is the unexamined longitudinal relationship between cognitive insight and mood. Therefore, in this study the level of cognitive insight, mania and depression were assessed in a total of 56 patients with bipolar disorder at baseline, four months and eight months follow-up. In addition, the cognitive insight of 35 healthy controls was assessed at baseline and at four months follow-up. The current research shows that self-reflectiveness and self-certainty remained stable over time in bipolar disorder. The improvement of mood did not affect the course of cognitive insight. However, at baseline higher levels of depression were correlated with more self-reflectiveness. In addition, self-reflectiveness was higher for bipolar disorder patients in comparison with the healthy controls. Our results could imply that higher levels of self-reflectiveness are a specific characteristic in bipolar disorder that is independent from an improvement in mood.

[The effect of mood-stabilising drugs on cytokine levels in bipolar disorder: a systematic review]. / De impact van stemmingsstabiliserende geneesmiddelen op cytokineconcen-traties bij patiënten met een bipolaire stoornis: een systematisch literatuur-onderzoek1.

ACHTERGROND: Veranderde cytokineconcentraties bij personen met een bipolaire stoornis ten opzichte van controle-personen suggereren een rol van het immuunsysteem in de pathofysiologie van bipolaire stoornis. Farmacotherapie is een belangrijke verstorende factor in klinisch onderzoek naar cytokineconcentraties.
DOEL: Evalueren van cytokineconcentraties bij medicatievrije patiënten met een bipolaire stoornis en van het effect van stemmingsstabiliserende geneesmiddelen op deze concentraties.
METHODE: We doorzochten systematisch PubMed en Embase naar klinische studies die cytokineconcentraties bij medicatievrije patiënten met een bipolaire stoornis beschrijven of het effect van een individueel stemmingsstabiliserend geneesmiddel op deze concentraties evalueren.
RESULTATEN: Van de 564 gescreende artikelen werden er 17 geïncludeerd. Resultaten bij medicatievrije patiënten toonden stemmingsgerelateerde cytokineveranderingen. Hoewel geen data over de kortetermijneffecten van lithium beschikbaar waren, was lithiumgebruik langer dan 2 maanden geassocieerd met normale cytokineconcentraties. Twee studies rapporteerden geen effect van valproïnezuur. We vonden geen studies over carbamazepine, lamotrigine of antipsychotica.
CONCLUSIE: Dit systematisch literatuuroverzicht toont stemmingsgerelateerde cytokineveranderingen bij medicatievrije patiënten met een bipolaire stoornis met de meeste evidentie voor een pro-inflammatoire immuunrespons tijdens manie. Euthymie en langdurig lithiumgebruik zijn geassocieerd met normale cytokineconcentraties. Er is een belangrijke methodologische heterogeniteit en onvoldoende replicatie tussen studies. Longitudinale studies met medicatievrije beginmetingen, gerandomiseerde monotherapeutische behandelprotocollen en nauwkeurige monitoring van stemming zijn noodzakelijk.
BACKGROUND: Alterations of the cytokine level in persons with bipolar disorder - when compared to controls - suggest that the immune system plays a role in the pathophysiology of bipolar disorder. Pharmacotherapy is an important confounding factor in clinical research on cytokine levels.
AIM: To evaluate the evidence on cytokine levels in medication-free bipolar disorder and to study the effects that single mood-stabilising drugs have on these levels.
METHOD: We searched PubMed and Embase systematically in order to single out clinical studies that reported on cytokine levels in medication-free bipolar disorder or that commented on the effects of single mood-stabilising drugs on cytokine levels.
RESULTS: Of the 564 articles that we screened, we detected 17 that were particularly relevant for our investigation. Results for medication-free patients point to mood-related alterations in cytokine levels. Although we found no data relating to short-term effects of lithium, the use of lithium in euthymic populations was associated with normal cytokine levels. Two studies reported no effect of valproate. We did not find any studies relating to carbamazepine, lamotrigine or antipsychotics.
CONCLUSION: Our systematic review of the literature suggests the presence of mood-related changes in cytokine levels in medication-free patients with bipolar disorder, with the most evidence for a proinflammatory response during a manic episode. Euthymia and long-term use of lithium use are associated with normal cytokine levels. There is considerable heterogeneity in the methods used in these studies and too little replication. Future research will have to include longitudinal studies with medication-free baseline measurements. It will also be necessary to draw up single-drug treatment protocols and to conduct intensive mood-related monitoring.

[Characteristics of catatonia in schizophrenia and mood disorders]. / Karakteristieken van katatonie bij schizofrenie en stemmingsstoornissen.

BACKGROUND: Catatonia is a psychomotor symptom cluster that co-occurs with schizophrenia and with mood disorders. The characterisation and the differentiation of psychomotor symptom clusters can contribute to a more accurate diagnosis and a better understanding of underlying neurobiological processes. AIM: To compare epidemiology, clinical presentation and treatment of catatonia in schizophrenia and in mood disorders. METHOD: We reviewed the literature using PubMed. RESULTS: Catatonia is highly prevalent in both schizophrenia and mood disorders, but is slightly more prevalent in the latter. In spite of a considerable overlap, there are differentiating trends in the catatonic symptom profile of schizophrenia and mood disorders. In both of these disorders catatonia is a marker for increasing severity of the course of the illness. Compared to catatonia in mood disorders, catatonia in schizophrenia has a poorer response to benzodiazepines and ECT. CONCLUSION: Catatonia in schizophrenia and mood disorders is characterized by a distinctive profile. Comparative research on clinical presentation and neurobiological processes is warranted in order to arrive at a more accurate characterisation of these psychomotor symptom clusters.
