Psicopatología como red causal compleja de síntomas interactivos / Psychopathology as a complex network of causally interacting symptoms

Resumen El modelo de la psicopatología como red de síntomas propone centrarse en las interacciones dinámicas y causales entre los síntomas constitutivos del problema clínico. La idea principal es que la activación de un síntoma clínico lleva a la activación de otro síntoma vecino. Las conexiones entre ellos pueden ser biológicas, psicológicas o sociales. Los trastornos mentales son concebidos como estados estables alternativos de redes de síntomas fuertemente conectados. Esto permite un modelo explicativo común para todos los trastornos mentales, un modelo integral de psicopatología. A pesar del éxito de este nuevo camino metodológico, la mayoría de la información relevante se encuentra publicada en inglés. En este artículo, se presenta, en idioma español, la teoría de la psicopatología como red de síntomas y su modelo, su relevancia para la investigación, docencia y práctica clínica de la psicología y la psiquiatría, a los fines de incrementar su difusión y diseminación.

Abstract Over the past years, psychopathology has frequently been represented as a complex system, where psychiatric symptoms are causally interconnected in a network architecture. The network theory of psychopathology has led to more than 300 novel publications, academic courses, methodology for estimating novel models, and freely available software. However, despite the success of this novel research avenue, all relevant information has mostly been published in English. This paper translates the network theory of psychopathology and its model, together with its relevance for research and clinical practice of psychology and psychiatry, to the Spanish language. To serve the dissemination of this theory, this paper serves as an introductory paper for Spanish scholars, for example, as a starting point to learn more about the approach or for academic courses. The main idea of the network theory of psychopathology is that the activation of one clinical symptom in the network leads to the activation of a neighboring symptom. If symptoms are strongly connected with each other, for example, excessive worry and insomnia, they are more likely to be in the same state, meaning that if a person faces a stressful life event such as losing one's job, the activation of the symptom excessive worry will increase the probability they will also suffer from insomnia. In this way, a whole symptom activation pattern develops from which mental disorders emerge. Mental disorders are conceived as stable states of strongly connected symptom networks, allowing for a common explanatory model for multiple mental disorders, thereby providing a comprehensive model of psychopathology. Traditional representations of mental disorders conceptualize symptoms as merely passive indicators of latent, underlying mental disorders which act as common causes for patients' symptomatology. The network theory of psychopathology flips the explanatory and statistical model: instead of focusing on one underlying cause or underlying causes, it proposes to study the direct interactions between these symptoms. This imposes two important implications for the conceptualization of mental disorders. First, symptoms are no longer statistically exchangeable since every symptom can have a different role in the onset and development of psychopathology. Some symptoms can be more important than others in keeping the whole system "stuck" in a disordered state. Second, comorbidity is conceptualized as clustering symptoms which are connected to each other via certain "bridge symptoms". Bridge symptoms are symptoms which are attributed to two (or more) mental disorders, such as Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD). If a person suffers from symptoms of MDD, such as loss of motivation and depressed mood, this can lead to the activation of bridge symptoms such as fatigue and concentration problems, which by themselves lead to the activation of GAD symptoms such as irritability and excessive worry.

Mental disorder caused by prion disease misdiagnosed as depressive episode：a case report / 四川精神卫生

This paper reported a case of a 29-year-old male patient with mental disorder caused by prion disease was misdiagnosed as depressive episode with somatic symptoms. The patient's symptoms were initially predominantly psychiatric， with progressive worsening of somatic symptoms， and he died more than 1 year after his first onset. Prion disease caused various manifestations of mental symptoms， which can easily lead to missed diagnosis and misdiagnosis. This paper discussed the case， in order to provide references for the clinical diagnosis of mental disorder caused by prion disease.

Psychiatric Symptoms after Infection Treated with Kampo Medicine, Mainly Chikujountanto / 日本東洋医学雑誌

I report two cases in which chikujountanto was effective for psychiatric symptoms after acute infection. Case 1 was a patient with depression after the common cold, which did not respond to the standard treatment with Western medicines using antidepressants, and was cured by honchiho with Kampo medicine. Case 2 was a patient with delirium after influenza, and kinds of untanto were highly effective. There is a neuroinflammatory hypothesis in the etiology of depression, and there are reports examining the clinical application of NSAIDS for neural inflammation, but the development of new pharmacotherapeutic drugs for targeting neuroinflammation has just only begun. On the other hand, it was found that the constituent crude drugs of Kampo medicine have anti-inflammatory effects, which is considered to be one of the factors leading to a cure. It was suggested that chikujountanto might be one of the differential prescriptions for psychiatric symptoms after suffering from the new coronavirus infection (COVID-19).

Prevalence of psychiatric symptoms and associated factors in the adult population from the area affected by the tailings dam rupture - Brumadinho Health Project / Prevalência de sintomas psiquiátricos e seus fatores associados na população adulta da área atingida pelo rompimento da barragem de rejeitos: Projeto Saúde Brumadinho

ABSTRACT: Objective: To examine the prevalence of psychiatric symptoms and associated factors in the adult population of Brumadinho (MG), after the dam collapse. Methods: We included 2,740 participants with information about symptoms of post-traumatic stress disorder (PTSD), depression, anxiety, thoughts of death/self-harm, and poor sleep quality collected in 2021. Prevalence values of all conditions were estimated to compare the prevalence of psychiatric symptoms with the participants' sociodemographic characteristics and place of residence. Pearson's c2 test was used, with Rao Scott's correction. Crude and adjusted logistic regressions estimated odds ratios and 95% confidence intervals to assess the association between psychiatric symptoms and participants' characteristics. Results: The most common condition was depressive symptoms (29.3%), followed by post-traumatic stress symptoms (22.9%) and anxious symptoms (18.9%). Regarding the association between participants' characteristics in the adjusted analysis, being a female and living in a mining area was positively associated with symptoms of PTSD, depression, anxiety, thoughts of death/self-harm, and poor sleep quality. A positive association was also found between high school education and post-traumatic stress symptoms. In contrast a negative association was found between being aged ≥60 years and symptoms of PTSD, depression, and anxiety. Conclusion: High prevalence values were found for all psychiatric symptoms after the dam failure in Brumadinho. Being a female, living in the mining area, being ≥60 years old, and having an educational level were all associated with the psychiatric symptoms investigated.

RESUMO: Objetivo: Examinar a prevalência dos sintomas psiquiátricos e seus fatores associados na população adulta de Brumadinho (MG), após o rompimento da barragem. Métodos: Foram incluídos 2.740 participantes com informações coletadas em 2021 sobre os sintomas de estresse pós-traumático (TEPT), depressão, ansiedade, ideias de morte/automutilação e pior qualidade do sono. Estimaram-se as prevalências de todas as condições. Para a comparação das prevalências dos sintomas psiquiátricos e as características sociodemográficas e local de moradia, empregou-se o teste χ2 de Pearson, com correção de Rao-Scott. Regressões logísticas brutas e ajustadas estimaram os odds ratios e intervalos de confiança de 95%, permitindo a avaliação da associação entre os sintomas psiquiátricos e as características dos participantes. Resultados: Os sintomas depressivos foram a condição mais prevalente (29,3%), seguidos pelos sintomas de TEPT (22,9%) e sintomas ansiosos (18,9%). Com relação à investigação da associação entre as características dos participantes na análise ajustada, observou-se que o sexo feminino e os moradores da área de mineração apresentaram relação positiva com os sintomas de TEPT, depressivos, ansiosos, ideia de morte e pior qualidade de sono. Também se encontraram associação positiva entre a escolaridade de nível médio e os sintomas de TEPT e associação negativa entre aqueles com ≥60 anos e os sintomas de TEPT, depressivos e ansiosos. Conclusão: Altas prevalências foram encontradas para todos os sintomas psiquiátricos após a ruptura da barragem em Brumadinho. Sexo feminino, local de moradia na área de mineração, ≥60 anos e escolaridade foram associados aos sintomas psiquiátricos investigados.

Early maladaptive schemas and harm avoidance as mediating factors between early life stress and psychiatric symptoms in adults

Objective: This study investigated how factors of temperament and early maladaptive schemas predict psychiatric symptoms, as well as how they mediate the relation between early life stress and psychiatric symptoms in adults. Methods: A cross-sectional study was conducted with a sample of 200 university students. Data was collected through a sociodemographic questionnaire, the Adult Self-Report Inventory, the Childhood Trauma Questionnaire, the Young Schema Questionnaire, and the Temperament and Character Inventory-Revised. Results: A model including early maladaptive schemas, harm avoidance (temperament factor), and early life stress explained 69% of the variation of the psychiatric symptoms; among the predictors, early maladaptive schemas explained 31% of psychiatric symptoms, while harm avoidance explained 25%. Most of the predictive power associated with early life stress can be better explained by early maladaptive schemas and, to a lesser extent, harm avoidance. Conclusion: By managing these processes therapeutically, deleterious effects associated with early life stress can be minimized.

Six Cases of Psychiatric Symptoms Successfully Treated with Shimotsuto-Containing Medication / 日本東洋医学雑誌

Six patients with psychiatric symptoms were successfully treated with shimotsuto-containing medication. Case 1 was a 13-year-old boy who complained of difficulty in getting up ; however, when he was treated with a focus on the decrease in his concentration, he was able to go to school after treatment. Case 2 was an 18-year-old girl who had also difficulty in getting up, but was able to go to school. Case 3 was a 10-year-old girl who was able to go to school partially after treatment. Case 4, a 42-year-old man with apprehension in socializing, showed improvement in socializing after taking medication containing shimotsuto. Case 5 had various complaints that were relieved after taking medication containing shimotsuto. Case 6 was a 56-year-old woman who had also multiple complaints ; however, the symptoms were alleviated with shimotsuto-containing medication. All patients experienced depression and anxiety. Four patients with decreased cortisol recovered after treatment with shimotsuto. From these results, shimotsuto is considered to improve concentration, judgment, and psychiatric symptoms by treating blood deficiency.

Association between socio-demographic profile and severity of cognitive impairment in elder patients presenting with new onset of psychiatric symptoms: a cross sectional study

Background: Cognitive impairment in the elderly is a common condition and, in most instances, primary care providers are the first point of contact for a patient and family. This study was aimed to find out the association between socio-demographic profile and severity of cognitive impairment in elder patients presenting with new onset of psychiatric symptoms.Methods: A cross sectional study was done among elder subjects (≥60 years of age) presented with new onset of psychiatric symptoms during one year period. A structured questionnaire was used to assess the socio-demographic details such as age, sex, education, occupation, socio-economic status and marital status. Mini International Neuropsychiatric interview and Montreal Cognitive Assessment scale were used for psychiatric diagnosis and severity of cognitive impairment grading, respectively. Association between socio-demographic data and cognitive impairment was statistically analyzed.Results: Among the 67 subjects included in the study, 76.2% had cognitive impairment. Majority of the subjects were females (56.7%) in the age group of 66-70 years. The association between cognitive impairment and sex (p=0.006), education (p=0.002) and occupation (p=0.015) were significant. But no significant association between cognitive impairment and marital status (p=0.0137) or socioeconomic status (p=0.400) was evidenced.Conclusions: Females in the age group of 66-70 years were more prevalent to cognitive impairment. The association between sex, education, occupation and severity of cognitive impairment was significant. No significant association between severity of cognitive impairment score and marital status or socioeconomic status was found.

Changes of serum neuropeptide Y and therapeutic intervention in patients with schizophrenia after drug therapy / 中国神经精神疾病杂志

Objective To explore the relationship between the serum neuropeptide Y (NPY) levels and the pathogenesis,therapeutic intervention of schizophrenia. Methods One hundard twenty-five patients with schizophrenia (case group) with no medication for at least 4-week and 136 healthy controls (control group) were evaluated by Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and Positive and Negative Syndrome Scala (PANSS). Simultaneously blood tests were performed to detect serum NPY levels. In the case group, PANSS was evaluated and blood collected again after 4 weeks of treatment with olanzapine. Result At the baseline,the serum NPY concentration was significantly lower in the case group than in control group (t=-5.79, P<0.01). The scores of RBANS and its factors were significantly lower in the case group than in control group (all P<0.01). The concentration was positively correlated with the score of the attention factor for RBANS scale (r=0.20, P=0.04). After treatment with olanzapine for 4 weeks,the serum NPY level in the case group was significantly increased (t=-2.23,P=0.03).The scores of PANSS total scale and subscale were significantly decreased(all P<0.01).There was no significant correlation between alterations of the serum level of NPY and PANSS total or subscale scores from baseline to 4-week (all P>0.05). Conclusion The present study has revealed a significant decrease in serum NPY levels in patients with schizophrenia which can be attenuated by treatment of Olanzapine.The action of Olanzapine may be related to the mechanism of action of Olanzapine.However,there is no correlation between alterations of the serum level of NPY and the improvement in the patientˊs clinical symptoms.

Psychiatric Findings in Suspected and Confirmed Middle East Respiratory Syndrome Patients Quarantined in Hospital: A Retrospective Chart Analysis

OBJECTIVE: Little is known about the psychiatric complications or risk factors for depression in suspected or confirmed Middle East Respiratory Syndrome (MERS) patients quarantined in hospital. METHODS: A retrospective chart review was performed of all the patients admitted to the acute MERS inpatient unit at the NMC during the 2015 outbreak. RESULTS: 30 (75%) were confirmed to be MERS-CoV positive among 40 admitted cases. Among the 24 MERS survivors, 17 (70.8%) exhibited psychiatric symptoms and 10 (41.7%) received a psychiatric diagnosis and medication during their hospital stay. Suspected MERS patients did not exhibit psychiatric symptoms or receive a psychiatric diagnosis. 27 suspected or confirmed MERS patients (age 41.15±18.64, male 37.0%) completed psychological assessments. A multiple linear regression analysis revealed that the Korean National Health and Nutrition Examination Survey-Short form and the Impact of Event Scale-Revised scores were significantly positively correlated with Patient Health Questionnaire-9 scores. CONCLUSION: Our findings indicate that the acute treatment of MERS-CoV infections in quarantine had a significant impact on the patients’ mental health. Furthermore, assessment of the risk factors for depression may identify vulnerable patients who require psychiatric care and attention during hospital quarantine.

Anxiety and depression symptoms in Brazilian sexual minority ecstasy and LSD users / Sintomas de ansiedade e depressão em brasileiros não heterossexuais usuários de ecstasy e LSD

Abstract Background This study examined drug use patterns and psychiatric symptoms of anxiety and depression among young Brazilian sexual minority ecstasy and LSD users and compared findings with those reported for their heterosexual peers. Method This cross-sectional study employed targeted sampling and ethnographic mapping approaches via face-to-face interviews conducted at bars and electronic music festivals using an adapted, semi-structured version of the Global Appraisal of Individual Needs questionnaire. The sample comprised 240 male and female young adults who had used ecstasy and/or LSD in the 90 days prior to the interview and who were not on treatment for alcohol and drug abuse. Results Of the 240 subjects enrolled (mean age: 22.9±4.5 years), 28.7% were gay or bisexuals. Multivariate regression analysis showed that the prevalence of depression symptoms in the past 12 months in the sexual minority group was 37% higher than among heterosexuals (prevalence ratio [PR]=1.79; 95% confidence interval [95%CI] 1.03-3.11; p=0.037). Conclusion Strategies should be developed to assess and address individual needs and treatment approaches should be tailored to address depressive symptoms in young, sexual minority club drug users.

Resumo Introdução Este estudo examinou os padrões de uso de drogas e os sintomas psiquiátricos de ansiedade e depressão entre brasileiros não heterossexuais usuários de ecstasy e/ou LSD e comparou os achados com aqueles relatados por seus pares heterossexuais. Método Este estudo transversal empregou amostragens direcionadas e abordagens de mapeamento etnográfico através de entrevistas presenciais realizadas em bares e festivais de música eletrônica usando uma versão adaptada e semiestruturada do questionário de Avaliação Global de Necessidades Individuais. A amostra incluiu 240 adultos jovens do sexo masculino e feminino que haviam usado ecstasy e/ou LSD nos 90 dias anteriores à entrevista e que não estavam em tratamento para abuso de álcool e drogas. Resultados Dos 240 sujeitos incluídos (idade média: 22,9±4,5 anos), 28,7% eram homossexuais ou bissexuais. A análise de regressão multivariada mostrou que a prevalência de sintomas de depressão nos últimos 12 meses no grupo não heterossexual foi 37% superior à dos heterossexuais [razão de prevalência (RP) = 1,79; intervalo de confiança de 95% (IC95%) 1.03-3.11; p=0,037]. Conclusão Estratégias devem ser desenvolvidas para avaliar e abordar as necessidades individuais, e as abordagens de tratamento devem ser adaptadas para sintomas depressivos em usuários de drogas jovens e não heterossexuais.

Latent class profile of psychiatric symptoms and treatment utilization in a sample of patients with co-occurring disorders

Objective: To identify symptom-based subgroups within a sample of patients with co-occurring disorders (CODs) and to analyze intersubgroup differences in mental health services utilization. Methods: Two hundred and fifteen patients with COD from an addiction clinic completed the Symptom Checklist 90-Revised. Subgroups were determined using latent class profile analysis. Services utilization data were collected from electronic records during a 3-year span. Results: The five-class model obtained the best fit (Bayesian information criteria [BIC] = 3,546.95; adjusted BIC = 3,363.14; bootstrapped likelihood ratio test p < 0.0001). Differences between classes were quantitative, and groups were labeled according to severity: mild (26%), mild-moderate (28.8%), moderate (18.6%), moderate-severe (17.2%), and severe (9.3%). A significant time by class interaction was obtained (chi-square [χ2[15]] = 30.05, p = 0.012); mild (χ2[1] = 243.90, p < 0.05), mild-moderate (χ2[1] = 198.03, p < 0.05), and moderate (χ2[1] = 526.77, p < 0.05) classes displayed significantly higher treatment utilization. Conclusion: The classes with more symptom severity (moderate-severe and severe) displayed lower utilization of services across time when compared to participants belonging to less severe groups. However, as pairwise differences in treatment utilization between classes were not significant between every subgroup, future studies should determine whether subgroup membership predicts other treatment outcomes.

Comparison of Therapeutic Efficacy of Olanzapine and Risperidone in the Treatment of Cognitive Function in Schizophrenia Patients / 中国药房

OBJECTIVE:To compare the therapeutic efficacy and safety of olanzapine and risperidone in the treatment of cognitive function in schizophrenia patients.METHODS:The information of 98 patients with schizophrenia were analyzed retrospectively and divided into control group and observation group according to therapy method,with 49 cases in each group.The patients receiving antipsychotic drugs were included in study after 7 d of drug withdrawal and cleaning.Control group received Risperidone tablet with initial dose of 1 mg,twice a day,orally,increasing to 4-6 mg within a week,twice a day,for consecutive 6 months.Observation group was given Olanzapine tablet with initial dose of 5 rag,twice a day,orally,increasing to 15-20 mg within a week,twice a day,for consecutive 6 months.Clinical efficacies of 2 groups were observed,and PANSS,WMS score (MQ score),TMT score (TMT-A connection time,TMT-A error number,TMT-B connection time,TMT-B error number score),WCST score (the number of completion classification,the number of sustained response,total number of errors,the number of persistent error and total correct number) were observed before and after treatment.The occurrence of ADR was recorded.RESULTS:There was no statistical significance in total response rate between 2 groups (93.88％ vs.97.96％,P＞0.05).After treatment,PANSS score,TMT-A connection time,TMT-A error number,TMT-B connection time,TMT-B error number,sustained response number,total error number and persistent error number scores in 2 groups were significantly lower than before treatment;PANSS score of observation group was significantly lower than that of control group;there was no statistical significance in other indexes betwee 2 groups.MQ score,the number of completion classification and total correct number score of 2 groups were significantly higher than before treatment,with statistical significance (P＜0.05 or P＜0.01);but there was no statistical significance between 2 groups(P＞0.05).The incidence of weight gain and lethargy in observation group was significantly higher than control group,and the incidence of extrapyramidal reaction,insomnia,headache,dizziness and dry mouth were significantly lower than control group,with statistical significance (P＜0.05).CONCLUSIONS:Therapeutic efficacy of olanzapine is similar to that of risperidone in the treatment of schizophrenia.Both of them can effectively improve cognitive function.Olanzapine is better than risperidone in improving psychiatric symptoms,but it increases the incidence of body weight gain and lethargy.

Psychiatric symptoms, substance use, and other medical conditions in patients with obesity who seek treatment for weight loss / Síntomas psiquiátricos, consumo de sustancias y otras condiciones médicas en pacientes con obesidad que buscan tratamiento para reducir peso

Abstract: INTRODUCTION: Scaling in obesity classes increases its effect on medical comorbidities and psychiatric symptoms. Anxiety and depression have a significant effect on treatment adherence and weight loss. OBJECTIVE: This study had three aims: a) to evaluate the prevalence of psychiatric symptoms; b) to evaluate the interactions between obesity classes and demographic variables in relation to psychiatric symptoms; and c) to analyze the interactions between obesity classes, demographic variables, and psychiatric symptoms in association with medical comorbidities in a sample of obese individuals seeking treatment for weight loss. METHOD: Medical record review of 22 weight loss clinics during January-December 2014. Binomial logistic regression was carried to assess univariate associations, second- and third-order interactions. RESULTS: Total sample was composed of 13,305 patients, mostly women (82.04%), married (53.66%), with elementary education (38.6%), mean body max index was 34.94 (SD = 4.39). The most prevalent psychiatric symptoms were anxiety (45.21%) and depression (16.36%). When analyzing interactions, it was found that men with class II obesity had higher odds for alcohol use (OR 1.56, IC 95% 1.10-2.22), and participants with obesity class III and married had more probability of diabetes II (OR 1.53, IC 95% 1.06-2.19). DISCUSSION AND CONCLUSION: Results show the complexity of the relation between demographic variables, psychiatric symptoms, medical comorbidities and obesity, underscoring the need to tailor treatments based in such variables, to promote adherence and weight loss.

Las comorbilidades más prevalentes fueron síntomas de ansiedad (45.21%) y depresión (16.36%). Al analizar las interacciones los hombres con obesidad tipo II tuvieron mayor probabilidad de consumo de alcohol (OR 1.56 IC 95% 1.10-2.22), y los participantes con obesidad tipo III y casados tuvieron mayor probabilidad de diabetes (OR 1.53 IC 95% 1.06-2.19). DISCUSIÓN Y CONCLUSIÓN: Los resultados muestran la compleja relación entre variables demográficas, obesidad, síntomas psiquiátricos y comorbilidades, implicando la necesidad de desarrollar programas de tratamiento que tomen en cuenta dichas variables para promover la adherencia al tratamiento y la reducción de peso.

Research progress of anti-N-methyl-D-aspartate receptor encephalitis / 中华实用儿科临床杂志

Anti-N-methyl-D-aspartate receptor (NMDAR) antibody encephalitis is an autoimmune encephalitis manifesting subacutely with prominent aberrant movements and psychiatric symptoms,which associated with antibodies against NR1 or NR2 subunits of the NMDAR.The disease is not rare,early diagnosis and immune treatment can improve prognosis and reduce the recurrence.The epidemiology,mechanisms,clinical presentation,treatment and prognosis of the disease were reviewed in order to enhance the cognition of anti-NMDAR encephalitis.

Anxiety Sensitivity and Comorbid Psychiatric Symptoms over the Course of Cognitive Behavioural Therapy for Panic Disorder.

Aims: Anxiety sensitivity (AS) might be the core vulnerability in the pathogenesis of AXIS I diagnosis and might be the important transdiagnostic target for the interventions for comorbid psychiatric symptoms in panic disorder (PD). This study aimed to examine the relationship of changes in the three factors of AS and changes in comorbid psychiatric symptoms over the course of cognitive behavioural therapy (CBT) for PD. Methodology: One hundred eighteen patients with PD were treated with manualized group CBT. Using multiple regression analysis, we examined the associations between the changes in subscales of Symptom Checklist-90 Revised (SCL-90-R) and the changes in factors of the Anxiety Sensitivity Index (ASI) involving Physical Concerns, Mental Incapacitation Concerns, and Social Concerns over the course CBT. Results: Reductions in Mental Incapacitation Concerns of ASI were related to decreases in 8 SCL-90-R scales, including Obsessive-Compulsive, Interpersonal Sensitivity, Depression, Hostility, Phobic Anxiety, Paranoid Ideation, Psychoticism, and GSI. Reductions in Physical Concerns were related to decreases in 5 SCL-90-R scales, including Somatization, Depression, Anxiety, Phobic Anxiety, and GSI. Discussion: The present study suggests that reductions in AS, especially mental and physical dimensions, predict comorbid psychiatric symptoms reduction over the course of CBT for PD.

Characteristics and Psychiatric Symptoms of Internet Gaming Disorder among Adults Using Self-Reported DSM-5 Criteria

OBJECTIVE: The Section III of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) proposed nine diagnostic criteria and five cut-point criteria for Internet Gaming Disorder (IGD). We aimed to examine the efficacy of such criteria. METHODS: Adults (n=3041, men: 1824, women: 1217) who engaged in internet gaming within last 6 months completed a self-report online survey using the suggested wordings of the criteria in DSM-5. Major characteristics, gaming behavior, and psychiatric symptoms of IGD were analyzed using ANOVA, chi-square, and correlation analyses. RESULTS: The sociodemographic variables were not statistically significant between the healthy controls and the risk group. Among the participants, 419 (13.8%) were identified and labeled as the IGD risk group. The IGD risk group scored significantly higher on all motivation subscales (p<0.001). The IGD risk group showed significantly higher scores than healthy controls in all nine psychiatric symptom dimensions, i.e., somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism (p<0.001). CONCLUSION: The IGD risk group showed differential psychopathological manifestations according to DSM-5 IGD diagnostic criteria. Further studies are needed to evaluate the reliability and validity of the specific criteria, especially for developing screening instruments.

Encefalitis por anticuerpos contra el receptor NMDA en tres pacientes pediátricos no asociados a tumor / Anti-NMDA receptor encephalitis in three pediatric patients without associated tumor

La encefalitis asociada a anticuerpos contra el receptor N metil D aspartato (anti-R NMDA) fue descrita por primera vez en 2005. Hoy en día es la segunda causa de encefalitis autoinmune en la población pediátrica. A diferencia de la presentación en adultos, en niños la encefalitis anti-R NMDA se asocia en menor escala a tumores y los trastornos de movimiento son más comunes. Aquí presentamos tres casos en niños, con un rango de edad entre 3 y 7 años. Las discinesias fueron el síntoma de presentación en el primer caso, y no se evidenciaron síntomas psiquiátricos. La paciente posteriormente desarrolló un estatus convulsivo y deterioro de conciencia, con alteraciones del lenguaje. El segundo caso, luego de un periodo prodrómico, desarrolló cambios comportamentales, discinesias, disautonomía, estatus convulsivo y deterioro de conciencia. En ambos casos el desenlace fue favorable con el tratamiento y en el seguimiento ambos pacientes se encontraron con buena clase funcional. Se concluye que una alta sospecha diagnóstica que permita la instauración de un tratamiento adecuado y oportuno lleva a una recuperación funcional en el tiempo, y requiere el apoyo de un equipo multidisciplinario.

The encephalitis associated with antibodies against N-methyl-D-aspartate Receptor (anti-R NMDA) was first described in 2005. Today it is the second leading cause of autoimmune encephalitis in the pediatric population. Unlike the presentation in adults, in children, it is less frequently associated with tumors but, movement disorders are more common. Here, we present two cases of children with anti-R NMDA encephalitis. The first one was three and a half years old at the time of diagnosis and the second was seven years old. Dyskinesias were the presenting symptom in the first case, and this patient showed no psychiatric symptoms. She subsequently developed a convulsive status and impaired consciousness with language disorders. The second case, after a prodromal period, developed behavioral changes, dyskinesias, dysautonomia, convulsive status and impaired consciousness. In both cases a good outcome was achieved with treatment and patients were found in good functional class status during the follow up. We conclude that reaching the appropriated diagnosis early on during the course of the disease allowed the establishment of the proper and timely treatment which leads to a good functional recovery over time. This usually requires the support of a multidisciplinary team.

Relation between emotion variability and psychiatric symptoms in middle school students / 中国心理卫生杂志

Objective:To investigate the relationship between emotion variability and assessment of psychiat-ric symptoms in middle school students,and validate that by structure equation modeling.Method:A total of 129 junior middle school students aged 13 -15 years were selected and assessed with the SCL-90 scale for psychiatric symptoms,the Adolescent Daily Emotion Regulation Questionnaire (ADERQ)for emotion regulation strategies, daily reconstruction method (DRM)for emotion variability during two weeks.Results:The students had higher positive emotion score than negative emotion score [(2.7 ±0.7)vs.(1.4 ±0.3),P <0.001],and higher negative emotion variability than positive emotion variability [(0.4 ±0.1 )vs.(0.3 ±0.1 ),P =0.012].Positive emotion variability and negative emotion variability were positively correlated with total scores of SCL-90 (r =0.34,0.24;Ps <0.001).Structural equation modeling revealed positive emotion variability,negative emotion variability and e-motion regulation strategy of cognitive appraisal had a direct effect on psychiatric symptoms (the path coefficient were 0.21,0.28,-0.24;Ps <0.001),cognitive immersed strategy had a direct effect on psychiatric symptoms and negative emotion variability(the path coefficient was 0.14,0.13,P =0.037,P =0.041).Conclusions:It suggests that both negative emotion variability and positive emotion variability play an important role in psychiatric symp-toms.

Objective Aortic dissection is accute in occurrence along with fast change , which is inclined to to induce psy-chotic symptoms and affect the lives of patients .The study was to investigate the effects of healthcare cooperative intervention on pa-tients with psychiatric symptoms secondary to aortic dissection . Methods We established medical cooperation organization structure to clarify the division of responsibility along with a quick assessment form , a process chart and a green channel for emergencey treat-ment.The above method was applied to intervene 32 patients with psychiatric symptoms secondary to aortic dissection and observe the diagnosis time , the time from diagnosis to surgery , the remission time of psychiatric symptoms , the incidence of adverse events and the length of stay. Results 32 patients were diagnosed within 30min followed by emergency surgery within 30min after diagnosis, which was 1-2 hours shorter than the previous diagnosis and surgery preparation time .5-21 d after surgery , psychiatric symptoms have been effectively controlled.Extubation, falling out of bed, self-injury or injury and other adverse events did not occur .No patient died, and the average length of stay was 13.5d, which was 1.75d shorter than the length of stay of previous similar patients . Conclusion The healthcare cooperation method can quickly identify patients with psychiatric symptoms secondary to aortic dissection , prevent adverse events and shorten the length of stay .
