In the present study, inspired by the EMDR (Eye Movement Desensitization and Reprocessing) protocol, the PEI approach is proposed to 30 patients with depressive disorder. The aim is to determine the implication of negative cognitions and dysphoric emotions resulting from a traumatic experience on their psychopathological disorder. Our analysis shows a predominance of memories linked to a lack of affective support during childhood. The negative cognitions identified confirm a feeling of insecurity generated either by a failure of affective bond or helplessness towards the event. An alteration of self-es- teem also emerges. Likewise, the present work also shows how psychotherapeutic care should consider narrowing the focus on traumatic experiences.展开更多

This proposal is not a research paper or a review of literature;instead, it is a treatment proposal that is novel and untested. CBASP psychotherapy, an empirically validated treatment, was developed originally to treat the persistently depressed adult. CBASP’s major focus of interpersonal consequation will be interfaced with a Play Therapy structured model to rectify the maladaptive preoperational functioning of five interpersonal types of problem-children. The types are classified interpersonally using D.J. Kiesler’s Interpersonal Message Inventory (IMI). Kiesler’s IMI is employed in this proposal as an ongoing assessment modality, a source of information to make treatment strategy consequation decisions, and thirdly as an evaluative outcome variable. The troubled child types described herein frequently become candidates for early-onset Persistent Depressive Disorder (PDD) unless rescued by successful treatment. The origins of early-onset PDD arise in dysfunctional households where toxic interpersonal relationships predominate: where “survival from abuse,” not growth, describes the child’s modal developmental experiences. These children are often exposed to either <em>serious traumas</em> (e.g., sexual abuse, loss of a parent, physical abuse, physical or emotional neglect) or <em>psychological insults</em> (e.g., continuous, and chronic verbal and nonverbal abuse). The result, in the most serious cases, is a maturational stunting at the preoperational stage of development which, as noted above, if not successfully resolved, thrusts the child into early-onset PDD.展开更多

文摘BACKGROUND Major depressive disorder(MDD)is the most frequent reason of disabled people in the world,as reported by the World Health Organization.However,the diagnosis of MDD is mainly based on clinical symptoms.CASE SUMMARY The clinical,genetic,and molecular characteristics of two Chinese families with MDD are described in this study.There were variable ages of onset and severity in depression among the families.Both Chinese families had a very low prevalence of MDD.The mitochondrial genomes of these pedigrees were sequenced and indicated a homoplasmic T3394C(Y30H)mutation,with the polymorphism located at a highly conserved tyrosine at position 30 of ND1.The analysis also revealed unique sets of mitochondrial DNA(mtDNA)polymorphisms originating from haplogroups M9a3 and M9a.CONCLUSION This finding of the T3394C mutation in two unrelated depressed patients provides strong evidence that this mutation may have a part in the etiology of MDD.However,In these two Chinese families having the T3394C mutation,no functional mt DNA mutation was observed.Therefore,T3394C mutations are related with MDD,and the phenotypic manifestation of these mutations may be affected by changes in nuclear genes or environmental factors.
文摘Serotonin deficiency in major depressive disorder(MDD)has formed the basis of antidepressant drug development and was originally attributed to induction of the major tryptophan(Trp)-degrading enzyme,liver Trp 2,3-dioxygenase(TDO),by cortisol,leading to decreased Trp availability to the brain for serotonin synthesis.Subsequently,the serotonin deficiency was proposed to involve induction of the extrahepatic Trp-degrading enzyme indoleamine 2,3-dioxygenase(IDO)by proinflammatory cytokines,with inflammation being the underlying cause.Recent evidence,however,challenges this latter concept,as not all MDD patients are immune-activated and,when present,inflammation is mild and/or transient.A wide range of antidepressant drugs inhibit the activity of liver TDO and bind specifically to the enzyme,but not to IDO.IDO induction is not a major event in MDD,but,when it occurs,its metabolic consequences may be masked and overridden by upregulation of kynurenine monooxygenase(KMO),the gateway to production of modulators of immune and neuronal functions.KMO appears to be activated in MDD by certain proinflammatory cytokines and antidepressants with anti-inflammatory properties may block this activation.We demonstrate the ability of the antidepressant ketamine to dock(bind)to KMO.The pathophysiology of MDD may be underpinned by both the serotonin deficiency and glutamatergic activation mediated respectively by TDO induction and N-methyl-D-aspartate receptor activation.Inhibition of TDO and KMO should be the focus of MDD pharmacotherapy.

文摘BACKGROUND Major depressive disorder(MDD)is a common and serious mental illness.Many novel genes in MDD have been characterized by high-throughput methods such as microarrays or sequencing.Recently,noncoding RNAs(ncRNAs)were suggested to be involved in the complicated environmental-genetic regulatory network of MDD occurrence;however,the interplay among RNA species,including protein-coding RNAs and ncRNAs,in MDD remains unclear.AIM To investigate the RNA expression datasets downloaded from a public database and construct a network based on differentially expressed long noncoding RNA(lncRNAs),microRNAs(miRNAs),and mRNAs between MDD and controls.METHODS Gene expression data were searched in NCBI Gene Expression Omnibus using the search term“major depressive disorder.”Six array datasets from humans were related to the search term:GSE19738,GSE32280,GSE38206,GSE52790,GSE76826,and GSE81152.These datasets were processed for initial assessment and subjected to quality control and differential expression analysis.Differentially expressed lncRNAs,miRNAs,and mRNAs were determined,Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were performed,and protein-protein interaction network was generated.The results were analyzed for their association with MDD.RESULTS After analysis,3 miRNAs,12 lncRNAs,and 33 mRNAs were identified in the competing endogenous RNA network.Two of these miRNAs were earlier shown to be involved in psychiatric disorders,and differentially expressed mRNAs were found to be highly enriched in pathways related to neurogenesis and neuroplasticity as per Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses.The expression of hub gene fatty acid 2-hydroxylase was enriched,and the encoded protein was found to be involved in myelin formation,indicating that neurological development and signal transduction are involved in MDD pathogenesis.CONCLUSION The present study presents candidate nc RNAs involved in the neurogenesis and neuroplasticity pathways related to MDD.

文摘Objectives:The prevalence and burden of disease of depression necessitates effective and accessible treatment options worldwide.Since April 2016,Japanese national health insurance has covered nurseadministered cognitive behavioral therapy(CBT)for mood disorders.However,empirical support for nurse-led CBT for depression in Asian countries,especially in Japan,is still lacking.This preliminary study aimed to examine the feasibility and acceptability of nurse-led group CBT for Japanese patients with depression.Methods:In this single-arm study,we evaluated the effects of a 6-week group CBT,led by trained nurses,on patients with major depression.The primary outcome was the Beck Depression Inventory-Ⅱ(BDI-Ⅱ).Assessments were conducted at the beginning and end of the intervention.Results:Of 25 participants screened,23 were eligible for the study(of these,three dropped out during the trial but were included in the analysis).Nurse-led group CBT led to significant improvements in the severity of depression(BDI-Ⅱ,P<0.001).The mean total BDI-Ⅱscore improved from 23.1(SD=7.56)to 12.4(SD=8.57),and the pre-to post-effect size was large(Cohen's d=1.33).After CBT,45%of the participants were judged to be treatment responders,and 34%met the remission criteria.Conclusions:Our preliminary findings indicate that 6 weeks of nurse-led group CBT produced a favorable treatment outcome for individuals with major depression in a Japanese clinical setting.The results of this study might encourage more Asian nurses to provide CBT as a part of their nursing practice.Further controlled trials that address the limitations of this study are required.

文摘BACKGROUND Although South Korea has developed and carried out evidence-based interventions and prevention programs to prevent depressive disorder in adolescents,the number of adolescents with depressive disorder has increased every year for the past 10 years.AIM To develop a nomogram based on a naïve Bayesian algorithm by using epidemiological data on adolescents in South Korea and present baseline data for screening depressive disorder in adolescents.METHODS Epidemiological data from 2438 subjects who completed a brief symptom inventory questionnaire were used to develop a model based on a Bayesian nomogram for predicting depressive disorder in adolescents.RESULTS Physical symptoms,aggression,social withdrawal,attention,satisfaction with school life,mean sleeping hours,and conversation time with parents were influential factors on depressive disorder in adolescents.Among them,physical symptoms were the most influential.CONCLUSION Active intervention by periodically checking the emotional state of adolescents and offering individual counseling and in-depth psychological examinations when necessary are required to mitigate depressive disorder in adolescents.
文摘Major depressive disorder(MDD)is a multifactorial disorder,where multiple susceptibility genes interact with environmental factors,predisposing individuals to the development of the illness.In this article,we reviewed different gene×environment interaction(G×E)studies shifting from a candidate gene to a genome-wide approach.Among environmental factors,childhood adversities and stressful life events have been suggested to exert crucial impacts on MDD.Importantly,the diathesis-stress conceptualization of G×E has been challenged by the differential susceptibility theory.Finally,we summarized several limitations of G×E studies and suggested how future G×E studies might reveal complex interactions between genes and environments in MDD.

文摘BACKGROUND Electroconvulsive therapy(ECT)is used to treat major depressive disorder(MDD).Relapse is often observed even after successful ECT,followed by adequate pharmaceutical treatment for MDD.AIM To investigate the diagnostic factors and treatment strategies associated with depression relapse.METHODS We analyzed the relationships between relapse,the diagnostic change from MDD to bipolar disorder(BP),and treatment after the initial ECT.We performed a 3-year retrospective study of the prognoses of 85 patients of the Shiga University of Medical Science Hospital.The relative risk of relapse of depressive symptoms was calculated based on the diagnostic change from MDD to BP.A receiver operating characteristic(ROC)curve was generated to evaluate the predictive accuracy of diagnostic changes from MDD to BP based on the duration between the first course of ECT and the relapse of depressive symptoms.RESULTS Eighty-five patients initially diagnosed with MDD and successfully treated with ECT were enrolled in the study.Compared with the MDD participants,more BP patients experienced relapses and required continuation and/or maintenance ECT to maintain remission(65.6%vs 15.1%,P<0.001;relative risk=4.35,95%CI:2.19-8.63,P<0.001).Twenty-nine patients experienced relapses during the three-year follow-up.In 21(72.4%,21/29)patients with relapse,the diagnosis was changed from MDD to BP.The duration from the first course of ECT to relapse was shorter for the BP patients than for the MDD patients(9.63±10.4 mo vs 3.38±3.77 mo,P=0.022);for most patients,the interval was less than one month.The relative risk of depressive symptoms based on diagnostic changes was 4.35(95%confidence interval:2.19–8.63,P<0.001),and the area under the ROC curve for detecting diagnostic changes based on relapse duration was 0.756(95%CI:0.562-0.895,P=0.007).CONCLUSION It may be beneficial to suspect BP and change the treatment strategy from MDD to BP for patients experiencing an early relapse.
文摘BACKGROUND The use of antidepressant therapy alone has a limited efficacy in patients with childhood trauma-associated major depressive disorder(MDD).However,the effectiveness of antidepressant treatment combined with psychodrama in these patients is unclear.AIM To evaluate the effectiveness of antidepressant treatment combined with psychodrama.METHODS Patients with childhood trauma-associated MDD treated with antidepressants were randomly assigned to either the psychodrama intervention(observation group)or the general health education intervention(control group)and received combination treatment for 6 mo.The observation group received general health education given by the investigator together with the“semi-structured group intervention model”of Yi Shu psychodrama.A total of 46 patients were recruited,including 29 cases in the observation group and 17 cases in the control group.Symptoms of depression and anxiety as well as coping style and resting-state functional magnetic resonance imaging were assessed before and after the intervention.RESULTS Symptoms of depression and anxiety,measured by the Hamilton Depression Scale,Beck Depression Inventory,and Beck Anxiety Inventory,were reduced after the intervention in both groups of patients.The coping style of the observation group improved significantly in contrast to the control group,which did not.In addition,an interaction between treatment and time in the right superior parietal gyrus node was found.Furthermore,functional connectivity between the right superior parietal gyrus and left inferior frontal gyrus in the observation group increased after the intervention,while in the control group the connectivity decreased.CONCLUSION This study supports the use of combined treatment with antidepressants and psychodrama to improve the coping style of patients with childhood trauma-associated MDD.Functional connectivity between the superior parietal gyrus and inferior frontal gyrus was increased after this combined treatment.We speculate that psychodrama enhances the internal connectivity of the cognitive control network and corrects the negative attention bias of patients with childhood trauma-associated MDD.Elucidating the neurobiological features of patients with childhood trauma-associated MDD is important for the development of methods that can assist in early diagnosis and intervention.

文摘BACKGROUND Major depressive disorder(MDD)tends to have a high incidence and high suicide risk.Electroconvulsive therapy(ECT)is currently a relatively effective treatment for MDD.However,the mechanism of efficacy of ECT is still unclear.AIM To investigate the changes in the amplitude of low-frequency fluctuations in specific frequency bands in patients with MDD after ECT.METHODS Twenty-two MDD patients and fifteen healthy controls(HCs)were recruited to this study.MDD patients received 8 ECT sessions with bitemporal placement.Resting-state functional magnetic resonance imaging was adopted to examine regional cerebellar blood flow in both the MDD patients and HCs.The MDD patients were scanned twice(before the first ECT session and after the eighth ECT session)to acquire data.Then,the amplitude of low-frequency fluctuations(ALFF)was computed to characterize the intrinsic neural oscillations in different bands(typical frequency,slow-5,and slow-4 bands).RESULTS Compared to before ECT(pre-ECT),we found that MDD patients after the eighth ECT(post-ECT)session had a higher ALFF in the typical band in the right middle frontal gyrus,posterior cingulate,right supramarginal gyrus,left superior frontal gyrus,and left angular gyrus.There was a lower ALFF in the right superior temporal gyrus.Compared to pre-ECT values,the ALFF in the slow-5 band was significantly increased in the right limbic lobe,cerebellum posterior lobe,right middle orbitofrontal gyrus,and frontal lobe in post-ECT patients,whereas the ALFF in the slow-5 band in the left sublobar region,right angular gyrus,and right frontal lobe was lower.In contrast,significantly higher ALFF in the slow-4 band was observed in the frontal lobe,superior frontal gyrus,parietal lobe,right inferior parietal lobule,and left angular gyrus.CONCLUSION Our results suggest that the abnormal ALFF in pre-and post-ECT MDD patients may be associated with specific frequency bands.

文摘Major depressive disorder(MDD)is highly prevalent and is a significant cause of mortality and morbidity worldwide.Currently,conventional pharmacological treatments for MDD produce temporary remission in<50%of patients;therefore,there is an urgent need for a wider spectrum of novel antidepressants to target newly discovered underlying disease mechanisms.Accumulated evidence has shown that immune inflammation,particularly inflammasome activity,plays an important role in the pathophysiology of MDD.In this review,we summarize the evidence on nuclear receptors(NRs),such as glucocorticoid receptor,mineralocorticoid receptor,estrogen receptor,aryl hydrocarbon receptor,and peroxisome proliferator-activated receptor,in modulating the inflammasome activity and depression-associated behaviors.This review provides evidence from an endocrine perspective to understand the role of activated NRs in the pathophysiology of MDD,and to provide insight for the discovery of antidepressants with novel mechanisms for this devastating disorder.

文摘PEI is a clinical approach which aims at assessing the links between psycho-trau- matic experience and depressive disorder. In the present study, inspired by the EMDR (Eye Movement Desensitization and Reprocessing) protocol, the PEI approach is proposed to 30 patients with depressive disorder. The aim is to determine the implication of negative cognitions and dysphoric emotions resulting from a traumatic experience on their psychopathological disorder. Our analysis shows a predominance of memories linked to a lack of affective support during childhood. The negative cognitions identified confirm a feeling of insecurity generated either by a failure of affective bond or helplessness towards the event. An alteration of self-es- teem also emerges. Likewise, the present work also shows how psychotherapeutic care should consider narrowing the focus on traumatic experiences.
文摘The current paper is a <em>theoretical proposal</em> that interfaces the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) and its emphasis on interpersonal consequences with the structured order of a Play Therapy Model for troubled 3 - 8-year-old children. This proposal is not a research paper or a review of literature;instead, it is a treatment proposal that is novel and untested. CBASP psychotherapy, an empirically validated treatment, was developed originally to treat the persistently depressed adult. CBASP’s major focus of interpersonal consequation will be interfaced with a Play Therapy structured model to rectify the maladaptive preoperational functioning of five interpersonal types of problem-children. The types are classified interpersonally using D.J. Kiesler’s Interpersonal Message Inventory (IMI). Kiesler’s IMI is employed in this proposal as an ongoing assessment modality, a source of information to make treatment strategy consequation decisions, and thirdly as an evaluative outcome variable. The troubled child types described herein frequently become candidates for early-onset Persistent Depressive Disorder (PDD) unless rescued by successful treatment. The origins of early-onset PDD arise in dysfunctional households where toxic interpersonal relationships predominate: where “survival from abuse,” not growth, describes the child’s modal developmental experiences. These children are often exposed to either <em>serious traumas</em> (e.g., sexual abuse, loss of a parent, physical abuse, physical or emotional neglect) or <em>psychological insults</em> (e.g., continuous, and chronic verbal and nonverbal abuse). The result, in the most serious cases, is a maturational stunting at the preoperational stage of development which, as noted above, if not successfully resolved, thrusts the child into early-onset PDD.
