DSM-IH-R Psychotic Disorders: procedural validity of the Mini International Neuropsychiatric Interview (MINI). Concordance and causes for discordance with the CIDI

Reliability and validity of facial expression recognition in the screening of generalized anxiety disorder

INTRODUCTION

Anxiety disorder is one of the most prevalent mental disorders in China. However, there are obvious subjective factors in the current assessment of anxiety disorders, which may lead to certain diagnostic errors. The identification and diagnosis of anxiety disorders can be further improved if objective biological indicators are added in the assessment process. The current research validates facial expression recognition as a screening tool to assist in detecting generalized anxiety disorder.

METHODS

Based on the International Affective Picture System, we constructed an aided diagnostic experimental paradigm and recorded their facial expression. The split-half reliability was displayed by the Pearson correlation heatmap. The paradigm, GAD-7 and HAMA scales were administered to 60 generalized anxiety disorder patients and 60 matched healthy controls to evaluate the criterion-related validity. Additionally, we conducted a diagnostic study by using MINI as a gold standard and calculated ROC analysis to examine the screening performance of the facial expressions.

RESULTS

The heatmap showed very high correlations (r > 0.60, PS < 0.05) along the diagonal of the square heatmap (from the bottom left corner to the top right). The Pearson correlation coefficients between the GAD-7, HAMA and seven facial expressions ranged from -0.35(neutral, P < 0.01) to 0.34(angry, P < 0.01). The intergroup effects of neutral, anger and fear emotions were statistically significant (F = 18.893, P < 0.001; F = 20.535, P < 0.001; F = 9.091, P = 0.003). ROC analysis showed AUC for neutral, angry and scared facial expressions were 0.723, 0.792 and 0.727 respectively.

CONCLUSION

This study constructed a tool for auxiliary screening of GAD patients and provided an objective automatic facial expression recognition method to assist psychological diagnosis.

Comorbidity of Depression and Diabetes: A Literature Review on Systemic Flaws in Healthcare and the Benefits of Collaborative Diagnosis and Treatment in Primary Care Settings

BACKGROUND

The increasing specialization and dispersion of healthcare systems have led to a shortage of resources to address comorbidities. Patients with coexisting mental and physical conditions are disadvantaged, as medical providers often only focus on the patient's mental illness while neglecting their physical needs, resulting in poorer health outcomes.

OBJECTIVE

This study aimed to shed light on the systemic flaws in healthcare systems that contribute to suboptimal health outcomes in individuals with comorbid diseases, including depression and diabetes. This paper also discusses the clinical and economic benefits of collaborative methods for diagnosing and treating depressive disorders in primary care settings.

METHODS

A comprehensive literature review of the relationship between depression and diabetes was conducted. The outcomes of the literature review were carefully analyzed. Several databases were searched using keywords such as "diabetes," "depression," "comorbidity," "prevalence," "epidemiology," and "risk factors" using Google Scholar and PubMed as search engines. The review and research papers written between 1961 and 2023 were our main focus.

RESULTS

This study revealed improved depressive symptoms and better blood sugar and blood pressure control. Additionally, individuals with comorbid depression and diabetes have higher direct and secondary medical costs. Antidepressants and psychological interventions are equally effective in treating depressive symptoms in patients with diabetes, although they have conflicting effects on glycemic control. For individuals with comorbid diabetes and depression, clear care pathways, including a multidisciplinary team, are essential for achieving the best medical and mental health outcomes.

CONCLUSION

Coordinated healthcare solutions are necessary to reduce the burden of illness and improve therapeutic outcomes. Numerous pathophysiological mechanisms interact with one another and may support the comorbidities of T2DM, and depressive disorders could exacerbate the course of both diseases.

Data-driven vs. psychological personality temperaments: theoretical and clinical utility of personality measures in psychiatry

Decades of research on personality identified dissociable psychological temperaments. Cloninger's temperament and character theory used a psychobiological approach to differentiate three major dimensions of personality: harm avoidance, novelty seeking, and reward dependence. Previous studies, heretofore, did not examine the correspondence between Cloninger's psychological temperaments and statistically independent data-driven components and how that could enhance the clinical utility of personality temperaments. In this study, we validated an Arabic version of the tri-dimensional personality questionnaire (TPQ) to construct data-driven personality temperaments using independent component analysis (ICA). Using SVM, we contrasted the clinical utility of data-driven personality vs. Cloninger's psychological temperaments in differentiating medication-naïve patients with major depressive disorder (N=244) and healthy subjects (N=1109). Data-driven personality components based on ICA showed very little overlap with Cloninger's original temperaments. Both Cloninger's temperaments and data-driven components revealed low internal consistency (for subscales) but high test-retest reliability. Cloninger's temperaments, however, showed a poor goodness-of-fit for the structure of the TPQ. Data-driven components significantly outperformed psychological TPQ temperaments with higher accuracy and recall but not precision. To our knowledge, this is the first study to examine the clinical utility of data-driven vs. psychological personality metrics using a sizeable sample of patients and healthy individuals. Our results could have wide implications for reexamining psychometric data to extract data-driven latent structures that can improve replicability, clinical utility, and cross-disciplinary inference.

Efficacy of tDCS to enhance virtual reality exposure therapy response in acrophobia: A randomized controlled trial

[BACKGROUND]: Virtual reality exposure therapy (VRET) has been recognized as an effective treatment for specific phobias and has the potential to overcome the limitations of traditional exposure therapy. The pursuit of non-invasive brain stimulation provides a practical means of augmenting VRET. Transcranial direct current stimulation (tDCS), a non-invasive neuromodulation technique, stimulates the medial prefrontal cortex (mPFC), with the potential to enhance the effects of exposure therapy. Therefore, we conducted a randomized controlled trial to examine whether tDCS enhanced the effects of VRET in acrophobia. [METHOD]: This study recruited 64 college students with significant fear of height (based on the Acrophobia Questionnaire, AQ). Finally, 61 participants were randomly allocated to the tDCS active-stimulated group (n = 30) or the sham-stimulated group (n = 31). After stimulation, VRET was conducted, and clinical indices were recorded. The AQ was used as the first primary outcome, and Subjective Units of Distress (SUDS) and the Heights Interpretation Questionnaire (HIQ) were used as secondary outcomes. [RESULT]: There was a significant reduction in psychometric and behavioral anxiety measurements from pre to post treatment as indicated by main effects for the factor time (AQ-Anxiety: F (2.60) = 139.55, p < 0.001, η2 = 0.83; AQ-Avoidance: F (2.60) = 53.73, p < 0.001, η2 = 0.69; HIQ: F (2.60) = 128.12, p < 0.001, η2 = 0.81; STAI-Y-S: F (2.60) = 15.44, p < 0.001, η2 = 0.34; BAI: F (2.60) = 73.81, p < 0.001, η2 = 0.71). Compared with the sham-stimulated group, the reduction of AQ-Anxiety and SUDS in the first exposure trial (F (2,60) = 8.56, p = 0.001, η2 = 0.23; t = 2.34, p = 0.024, d = 0.61) was significantly faster in the active group. At follow-up, there was also a further reduction in AQ anxiety and avoidance (Anxiety: M = 56.51 ± 27.19; main effect time F (1,60) = 25.16, p < 0.001, η2 = 0.35; Avoidance: M = 12.57 ± 7.97; main effect time F (1,60) = 31.40, p < 0.001, η2 = 0.45) without interaction time*group (Anxiety: F (1.60) = 0.12, p = 0.740, η2 = 0.00; Avoidance: F (1.60) = 0.64, p = 0.430, η2 = 0.02). [CONCLUSION]: Results could be explained tDCS could accelerate the effects of VRET on acrophobia by stimulating mPFC, indicating that tDCS may be used as an enhancement technique for exposure therapy for specific phobias.

Dysregulated cerebral blood flow, rather than gray matter Volume, exhibits stronger correlations with blood inflammatory and lipid markers in depression

Arterial spin labeling (ASL) can be used to detect differences in perfusion for multiple brain regions thought to be important in major depressive disorder (MDD). However, the potential of cerebral blood flow (CBF) to predict MDD and its correlations between the blood lipid levels and immune markers, which are closely related to MDD and brain function change, remain unclear. The 451 individuals - 298 with MDD and 133 healthy controls who underwent MRI at a single time point with arterial spin labelling and a high resolution T1-weighted structural scan. A proportion of MDD also provided blood samples for analysis of lipid and immune markers. We performed CBF case-control comparisons, random forest model construction, and exploratory correlation analyses. Moreover, we investigated the relationship between gray matter volume (GMV), blood lipids, and the immune system within the same sample to assess the differences in CBF and GMV. We found that the left inferior parietal but supramarginal and angular gyrus were significantly different between the MDD patients and HCs (voxel-wise P < 0.001, cluster-wise FWE correction). And bilateral inferior temporal (ITG), right middle temporal gyrus and left precentral gyrus CBF predict MDD (the area under the receiver operating characteristic curve of the random forest model is 0.717) and that CBF is a more sensitive predictor of MDD than GMV. The left ITG showed a positive correlation trend with immunoglobulin G (r = 0.260) and CD4 counts (r = 0.283). The right ITG showed a correlation trend with Total Cholesterol (r = -0.249) and tumour necrosis factor-alpha (r = -0.295). Immunity and lipids were closely related to CBF change, with the immunity relationship potentially playing a greater role. The interactions between CBF, plasma lipids and immune index could therefore represent an MDD pathophysiological mechanism. The current findings provide evidence for targeted regulation of CBF or immune properties in MDD.

The severity of addiction mediates loneliness and cortical volume in internet gaming disorder

Internet gaming disorder (IGD) subjects reported higher loneliness scores than healthy controls. However, the neural correlates underlying the association between loneliness and IGD remain unclear. Thus, the aim of this study was to explore the relationship between loneliness, online gaming addiction and brain structure. In the current study, structural MRI data were acquired from 84 IGD subjects and 103 matched recreational game users (RGUs). We assessed and compared their addiction severity, loneliness scores, and cortical volumes and analyzed the correlations among these values. Significant correlations were found between loneliness scores and brain volumes in the postcentral cortex, the medial orbitofrontal cortex, the rostral anterior cingulate cortex, and the temporal cortex. In addition, the addiction severity scores partly mediated the relationship between loneliness score and cortical volume in IGD. The results showed that participants with extreme loneliness had significant correlations with brain regions responsible for executive control, social threat surveillance and avoidance. More importantly, the severity of addiction mediates loneliness and cortical volume. The findings shed new insight into the neural mechanisms of loneliness and IGD and have implications for potential treatment.

Psychosocial factors of insomnia in depression: a network approach

BACKGROUND

Insomnia symptoms in patients with major depressive disorder (MDD) are common and deleterious. Childhood trauma, personality traits, interpersonal distress, and social support contribute to insomnia, but how they interact to affect insomnia remains uncertain.

METHODS

A total of 791 patients with MDD completed the Insomnia Severity Index, Eysenck Personality Questionnaire, Interpersonal Relationship Comprehensive Diagnostic Scale, Childhood Trauma Questionnaire, Social Support Rating Scale and Hamilton Depression Scale-17. This study utilized network analyses to identify the central symptoms of insomnia and their associations with psychosocial factors.

RESULTS

Worrying about sleep was identified as the central symptom in the insomnia network, insomnia and associated personality network, insomnia and associated interpersonal disturbance network, insomnia and associated childhood trauma network, insomnia and associated social support network, and the integrated network of insomnia symptoms and associated psychosocial factors. In the networks of insomnia symptoms and individual psychosocial factors, most psychosocial factors (other than childhood trauma) were directly or indirectly related to insomnia symptoms; however, neuroticism was the only factor directly associated with insomnia symptoms before and after controlling for covariates. In the final integrated network of insomnia symptoms and psychosocial factors, neuroticism was a bridge node and mediated the relationships of social support and interpersonal disturbances with insomnia symptoms, which is clearly presented in the shortest pathways.

CONCLUSIONS

Worrying about sleep and neuroticism were prominent in the integrated network of insomnia symptoms and associated psychosocial factors, and the edge between them connected psychosocial factors and insomnia symptoms in MDD patients.

The Association between Nonsuicidal Self-Injury and Perfectionism in Adolescence: The Role of Mental Disorders

Previous evidence has drawn attention to the fact that maladaptive perfectionism is a risk factor for engagement in nonsuicidal self-injury (NSSI). Until now, few studies have examined this topic, especially among community adolescents. The aim of this study was to explore the relationship between perfectionism dimensions and NSSI functions to examine the potential mediating effect of mental disorders. Altogether, 146 Hungarian community adolescents (ages 13-18 years) were involved. All participants completed the Hungarian adaptation of the Inventory of Statements about Self-Injury (ISAS), the Frost Multidimensional Perfectionism Scale (FMPS), and the Mini International Neuropsychiatric Interview Kid. To analyse the interrelationships among NSSI, perfectionism, and mental disorders, we conducted regression and network analysis. Of the 146 adolescents, 90 (61.64%, girls: 71.11%) engaged in NSSI. The Concern over Mistakes and Doubts about Action scales of the FMPS significantly and positively predicted both NSSI intrapersonal and interpersonal motivation, with comparable effect sizes, and this association was fully mediated by anxiety disorders. There was a significant direct negative relationship between the FMPS Organisation dimension and both main NSSI functions. This study draws attention to an increasing trend and the extremely high NSSI prevalence rate among community adolescents. Adolescents with perfectionistic concerns are at heightened risk for anxiety disorders, which can increase their vulnerability to NSSI engagement.

Physical Activity During Adolescence and Mental Health in Early Adulthood: Findings From the 1993 Pelotas Birth Cohort Study

BACKGROUND

Low prevalence of physical activity (PA) and a high prevalence of mental health problems are common among youth. The aim of this study was to evaluate the association between PA during adolescence and depression and anxiety disorders in young adulthood.

METHODS

Data from the 1993 Pelotas (Brazil) Birth Cohort Study were analyzed. Leisure-time PA and total PA (leisure plus commuting) were evaluated at 11, 15, and 18 years using self-reported data. PA was evaluated at each age separately and during adolescence, considering the number of times participants reached PA recommendations. Depression and anxiety were assessed through Mini International Neuropsychiatric Interview at 22 years. Crude and adjusted association analyses were performed using Poisson regression with robust error variance, providing prevalence ratios and 95% confidence intervals.

RESULTS

Three thousand two hundred and forty-seven participants were included in the study. In the adjusted analyses, active participants in leisure-time PA (≥300 min/wk) and total PA at 11 years were less likely to be depressed at age 22 (prevalence ratios: 0.54; 95% confidence interval, 0.33-0.89; prevalence ratios: 0.63; 95% confidence interval, 0.41-0.97). For leisure-time PA, the more PA recommendations were met during adolescence, the lower the prevalence of depression. There was no association when PA variables were evaluated separately at 15 and 18 years and between PA and anxiety after controlling for potential confounders.

CONCLUSIONS

Early adolescence appears to be a sensitive period for PA benefits on depression in early adulthood. The more timepoints reaching PA recommendations during adolescence, the lower the risk of depression. On the other hand, PA during adolescence was not associated with anxiety in young adults.

The relationship between childhood trauma and insomnia among college students with major depressive disorder: Mediation by the role of negative life events and dysfunctional attitudes

BACKGROUND

Insomnia is a common problem among patients with major depressive disorder (MDD). According to previous studies, the development and severity of Insomnia are influenced by childhood trauma experience. Furthermore, negative life events and dysfunctional attitudes may also mediate the impact. So, this study aimed to examine the association between childhood trauma, negative life events, dysfunctional attitudes and insomnia and investigate how negative life events and dysfunctional attitudes mediate the relationship between childhood trauma and insomnia in MDD.

METHOD

This cross-sectional study recruited 621 college students with MDD. The Childhood Trauma Questionnaire (CTQ), Life Event Scale (LES), Dysfunctional Attitude Scale (DAS), Insomnia Severity Index (ISI), and Hamilton Depression Scale-17 (HAMD-17) were used to assess participants' psychosocial factors. Descriptive analysis, Chi-square test, t-test, Pearson correlations, and serial mediation analyses were used in data analysis. In order to eliminate the influence of the severity of depression symptoms, severity of depression symptoms was used as a control variable in this study.

RESULTS

There were 166 (26.7%) participants having clinical insomnia (ISI score > 14). After controlling for the effect of severity of depression symptoms, results of serial mediation analyses determined that childhood trauma has a direct (Estimate = 0.109, 95%CI: 0.023,0.190) and indirect (Estimate = 0.090, 95%CI: 0.054,0.137) impact to insomnia. The indirect impact of childhood trauma on insomnia through the pathways of negative life events alone (Estimate = 0.050, 95%CI: 0.024,0.093), dysfunctional attitudes alone (Estimate = 0.027, 95%CI: 0.008,0.050), and negative life events to dysfunctional attitudes (Estimate = 0.013, 95%CI: 0.006,0.024) were significant.

CONCLUSIONS

This study demonstrates that screening for childhood trauma should be considered when treating insomnia in college students with MDD. Managing negative life events and dysfunctional attitudes may mitigate the negative impact of childhood trauma on insomnia in college students with MDD.

Depression in mothers at childhood: Direct and indirect association with problematic gaming in late adolescence/young adulthood

OBJECTIVES

Little is known about the relationship between depression in mothers and problematic gaming in their children. Therefore, we aimed to investigate the potential role of mothers' depression in childhood as a risk factor for problematic gaming in their offspring in late adolescence/young adulthood.

METHODS

We assessed data from 1557 participants on three waves (T0 collected in 2010/2011, T1 in 2013/2014, and T2 in 2018/2019) of a large Brazilian school-based cohort. Mother's depression at T0 was tested as a predictor of problematic gaming at T2 in a logistic regression model. In mediation analyses, we individually assessed internalizing or externalizing disorders at T1 as mediators in this association, with participants' sex being tested as a moderator in both models. Inverse probability weights were used to account for sample attrition at T2. All models were adjusted for maternal and participant-related covariates.

RESULTS

Mother's depression at T0 was significantly associated with problematic gaming at T2 (OR = 2.09, p < 0.001) even after adjusting for multiple confounding factors. The presence of any internalizing disorder at T1 was a partial mediator of this relationship, accounting for 8.18% (p = 0.032) of the total effect, while the presence of any externalizing disorder at T1 was not a significant mediator. Participants' sex was not a significant moderator in mediation models.

CONCLUSIONS

These findings suggest mother's depression in childhood as a risk factor for problematic gaming in later developmental stages, which may be partially mediated by internalizing psychopathology.

Longitudinal associations between positive attributes and psychopathology and their interactive effects on educational outcomes

Psychopathology is associated with impaired learning and early termination of schooling, whereas positive attributes are associated with better educational outcomes. However, it is important to understand if and how psychopathology and positive attributes longitudinally impact each other so we could shed light on where to intervene to promote educational outcomes through these constructs. A large prospective school-based community cohort of youths (5-15 years of age, 45% female) were assessed and followed up for 3 years (n = 2010; 80% retention). We assessed the longitudinal impact of positive attributes (Youth Strength Inventory) and psychopathology (bifactor model of Strengths and Difficulties Questionnaire) using a cross-lagged panel model. We also used generalized mixed effects models to investigate how these both constructs predict school dropout and literacy, adjusting for confounders and testing their interaction. Positive attributes negatively predicted, and were negatively predicted by, the general factor of psychopathology and conduct problems in the cross-lagged panel model. Positive attributes (OR = 0.57, 95% CI [0.44, 0.73], p < 0.001) and specific conduct symptoms (OR = 2.33, 95% CI [1.64, 3.33], p < 0.001) predicted school dropout, whereas the general factor of psychopathology predicted lower literacy ability (β =  - 0.08, 95% CI [- 0.11, - 0.05], p < 0.001). However, the protective association of positive attributes on school dropout decreases as the general factor of psychopathology increases. These findings provide new evidence that positive attributes and psychopathology mutually influence each other over development and have interactive effects on educational outcomes.

Prevalence of attention deficit hyperactivity disorder in an adult mental health service in the Republic of Ireland

OBJECTIVE

Attention Deficit Hyperactivity Disorder (ADHD) is well recognised in childhood. However, recognition that it commonly persists into adulthood is relatively recent. This study is the 2nd phase of a two-phase epidemiological investigation of the prevalence of adult ADHD in outpatients in Ireland.

METHOD

In phase-1, 634 participants were screened with Adult ADHD Self-Report Scale (ASRS) and Wender Utah Rating Scale (WURS). Those scoring positive in both scales have been invited to participate in the 2nd phase where the scales Conners' Adult ADHD Diagnostic Interview (CAADID), Mini International Neuropsychiatric Interview (MINI), and Global Assessment of Functioning (GAF) were administered, plus clinical evaluation based in DSM-5.

RESULTS

131 were eligible, 110 participated (84.0%). Using the CAADID (DSM-IV criteria) 71 were diagnosed with ADHD. Projecting to the total sample (N = 634) the prevalence was 13.25%, CI:95%:10.71-16.14. Converting the DSM-IV criteria to DSM-5, 89 had ADHD (prevalence:16.72%, CI: 13.9-19.86). Using clinical evaluation, 86 were diagnosed with ADHD (prevalence:16.09%, CI:13.31-19.18). Only 3 cases were diagnosed before with ADHD. Comorbidity was higher in those with ADHD, with the median number of additional diagnoses 2 (min 0 max 8, IQR 3) Also, they had significantly higher rates of depression and recurred depression. Agreement between DSM-IV and DSM-5 was high (rho = 0.90, p < .0001).

CONCLUSIONS

High rates of undiagnosed ADHD were found to be present among AMHS attendees. Clinicians in AMHS need to be knowledgeable and alert to possible ADHD among their caseloads, and offer appropriate intervention. Interventions are urgently required to increase the detection and treatment of adult ADHD.

Childhood trauma, inflammatory biomarkers and the presence of a current depressive episode: Is there a relationship in subjects from a population study?

This study aims to compare the serum cytokine levels between controls, individuals with a current depressive episode (CDE) with childhood trauma and individuals with CDE without childhood trauma. This is a cross-sectional with paired sample nested in a population-based study. For the purposes of the current study, subjects who had psychotic symptoms, generalized anxiety disorder, and who refused to perform blood collection were excluded. Subsequently, only individuals who had a current depressive episode were selected (n = 76). Another 76 subjects were randomly paired by sex and age, constituting a population control group. The measurements of serum cytokine levels were performed using the multiplex analysis method. In the group with a CDE, when compared to the population control group, the following cytokines were high: IL-1β, IL-2, IL-4, IL-6, IL-17A, IFN-γ and TNF-α (p < 0.05). On the other hand, there was a decrease in the levels of cytokines IL-10 (p = 0.027) and IL12p70 (p = 0.001). Bonferroni test demonstrates that there is no statistically significant difference in serum cytokine levels between subjects with a CDE, with and without trauma (p > 0.05). In a multivariable logistic regression, adjusting for socioeconomic status, tobacco, alcohol and illicit drugs abuse/dependence, and use of psychiatric medication, we found that cytokines serum levels remained associated with CDE even when adjusted for these potential confounders. Our findings demonstrate that monitoring cytokine levels and immune function may be beneficial in preventing the development of a CDE. However, future research is necessary to investigate the impact of trauma on the relationship between inflammation and CDE.

Superior temporal gyrus and cerebellar loops predict nonsuicidal self-injury in major depressive disorder patients by multimodal neuroimaging

In major depressive disorder (MDD) patients, nonsuicidal self-injury (NSSI) is a common comorbidity, and it is important to clarify the underlying neurobiology. Here, we investigated the association of NSSI with brain function and structure in MDD patients. A total of 260 MDD patients and 132 healthy controls (HCs) underwent resting-state functional magnetic resonance imaging and three-dimensional T1-weighted structural scans. NSSI behaviour was assessed through interviews. Voxel-based morphometry analysis (VBM), regional homogeneity analysis (ReHo), functional connectome topology properties and network-based statistics were used to detect the differences in neuroimaging characteristics. Finally, the random forest method was used to evaluate whether these factors could predict NSSI in MDD. Compared with HCs, MDD patients with a history of NSSI showed significant right putamen grey matter volume (GMV), right superior orbital frontal cortex ReHo, left pallidum degree centrality, and putamen-centre function network differences. Compared to MDD subjects without NSSI, those with past NSSI showed significant right superior temporal gyrus (STG) GMV, right lingual gyrus ReHo, sigma and global efficiency, and cerebellum-centre function network differences. The right STG GMV and cerebellum-centre function network were more important than other factors in predicting NSSI behaviour in MDD. MDD patients with a history of NSSI have dysregulated spontaneous brain activity and structure in regions related to emotions, pain regulation, and the somatosensory system. Importantly, right STG GMV and cerebellar loops may play important roles in NSSI in MDD patients.

Obsessive-Compulsive Disorder with Psychotic Features: Is It a Clinical Entity?

(1) Background: Even though the comorbidity of obsessive-compulsive disorder (OCD) and a psychotic disorder (PD), such as schizophrenia, is being increasingly recognized, the impact of this comorbidity on the clinical presentation, including insight into obsessive-compulsive symptoms and the functioning of OCD, remains unclear. (2) Methods: To investigate clinical differences between OCD patients with and without PD, 86 Japanese outpatients who met the DSM-IV-TR criteria for OCD were recruited and divided into two groups: 28 OCD patients with PD, and 58 OCD patients without PD. The two groups were cross-sectionally compared in terms of their sociodemographic profiles and clinical characteristics, including the DSM-IV-TR insight specifier and the Global Assessment of Functioning (GAF). (3) Results: The results showed that OCD patients with PD scored lower on both the insight and GAF assessments. (4) Conclusions: The present study suggests that comorbid PD in OCD is a clinical entity.

Suicidal ideation in college students having major depressive disorder: Role of childhood trauma, personality and dysfunctional attitudes

BACKGROUND

Suicide in college students is a major public health concern. Suicidal ideation (SI) is associated with childhood trauma, personality, dysfunctional attitudes and depressive symptoms, but how they interact to predict SI remains unclear.

METHODS

Using cross-sectional design and convenience sampling method, a survey was conducted among 565 college students having major depressive disorder (MDD). The Childhood Trauma Questionnaire, Eysenck Personality Questionnaire, Dysfunctional Attitudes Scale and Hamilton Depression Scale assessed participants' psychosocial factors. Chi-square test, t-test, Pearson correlation, and Structural Equation Model were used in data analysis.

RESULTS

Overall, 66.02% of participants with MDD had SI. Those with SI showed significant differences in physical abuse, emotional abuse, physical neglect, emotional neglect, psychoticism, neuroticism, extroversion, dysfunctional attitudes and depressive symptoms compared with those without SI. Childhood trauma, psychoticism, neuroticism, extroversion and dysfunctional attitudes affected SI through chain mediation. In addition, depressive symptoms, psychoticism, neuroticism and extroversion directly affected SI.

LIMITATIONS

The convenience sampling method may limit the generalizability of the findings. Results may be biased due to the self-report nature of the data collection procedure, the number of research subjects and differences in suicide risk assessment. The cross-sectional study cannot be used to infer causality.

CONCLUSIONS

The factors of childhood trauma, personality and dysfunctional attitudes affect SI through chain mediation. In addition, depressive symptoms and personality independently predict the occurrence of SI.

Catechol-O-methyltransferase activity in individuals with substance use disorders: a case control study

BACKGROUND

Impulsivity and substance use disorders (SUD) have been both associated with changes in dopaminergic processes. In this study, we intended to evaluate the dopaminergic function in imprisoned SUD offenders through the determination of s-COMT activity.

METHODS

The study included 46 male individuals from a Portuguese penal institution. The participants were assessed through a battery of standardised instruments: Psychopathy Checklist-Revised (PCL-R), Barratt Impulsivity Scale Version 11 (BIS-11), and the European version of the Addiction Severity Index (EuropASI). In addition, s-COMT erythrocyte activity was evaluated.

RESULTS

Overall, 73.9% (n = 34) of the individuals had Antisocial personality disorder (ASPD) and 58.7% (n = 27) presented SUD. We evidenced, for the first time, that, in individuals with SUD, s-COMT activity was correlated with the severity of drug dependence (EuropASI) (p = 0.009), and with BIS-11 factors self-control (p < 0.0001) and non-planning (p = 0.002).

CONCLUSIONS

This study opens new perspectives regarding the pharmacological intervention on substance dependence through the interference on dopamine pathways.

Suicide and Epilepsy

PURPOSE OF REVIEW

Epilepsy has a bidirectional association with suicidality, and epilepsy patients are at much higher risk for suicide than the general population. This article reviews the recent literature on suicide risk factors, assessments, and management as they pertain specifically to suicidality in people with epilepsy, a population that requires unique considerations.

RECENT FINDINGS

Risk factors for suicidality include younger age (independent of comorbid psychiatric disorders), poor social support, psychiatric comorbidity (depression, anxiety, obsessive-compulsive symptoms, and alcohol use), and epilepsy-related factors (more frequent seizures, temporal lobe epilepsy, and drug-resistant epilepsy). Most clinicians agree with the need for addressing suicidality; however, there is inconsistency in the approach to caring for these patients. An example neurology clinic-based approach is outlined. Although PWE are at risk for suicide and risk factors have been characterized, care gaps remain. Screening strategies may help close these gaps.

Dimensional (premenstrual symptoms screening tool) vs categorical (mini diagnostic interview, module U) for assessment of premenstrual disorders

BACKGROUND

Premenstrual syndrome (PMS) is the constellation of physical and psychological symptoms before menstruation. Premenstrual dysphoric disorder (PMDD) is a severe form of PMS with more depressive and anxiety symptoms. The Mini international neuropsychiatric interview, module U (MINI-U), assesses the diagnostic criteria for probable PMDD. The Premenstrual Symptoms screening tool (PSST) measures the severity of these symptoms.

AIM

To compare the PSST ordinal scores with the corresponding dichotomous MINI-U answers.

METHODS

Arab women (n = 194) residing in Doha, Qatar, received the MINI-U and PSST. Receiver Operating Characteristics (ROC) analyses provided the cut-off scores on the PSST using MINI-U as a gold standard.

RESULTS

All PSST ratings were higher in participants with positive responses on MINI-U. In addition, ROC analyses showed that all areas under the curves were significant with the cutoff scores on PSST.

CONCLUSION

This study confirms that the severity measures from PSST can recognize patients with moderate/ severe PMS and PMDD who would benefit from immediate treatment.

The partial µ-opioid agonist buprenorphine in autism spectrum disorder: a case report

Background

There are currently no approved medications for impaired social cognition and function, core symptoms of autism spectrum disorder. We describe marked improvement of these symptoms with long-term low-dose administration of the partial µ-opioid agonist buprenorphine. We discuss these observations in the context of a role for endogenous opioid systems in social attachment, and theories integrating those findings mechanistically with autism spectrum disorder.

Case presentation

M, a 43-year-old Caucasian male, is medically healthy. Despite social difficulties since childhood, he completed high school with better-than-average grades, but failed university education. A psychiatric evaluation in his twenties diagnosed attention deficit hyperactivity disorder but also noted symptoms of coexisting autism spectrum disorder. M accidentally came across buprenorphine in his late twenties and experienced progressively improved social functioning on a low daily dosage (0.5–1.0 mg/day), an effect maintained for 15 years. He lived independently and maintained a part-time occupation. After abrupt discontinuation of treatment, his autistic symptoms returned, and function deteriorated. Following evaluation by our team, buprenorphine was resumed, with gradual return to prior level of functioning. An attempt to formally evaluate M both on and off medication was agreed with him and approved by the Swedish Ethics Authority, but medication had to be resumed when the patient worsened following discontinuation.

Conclusions

According to the µ-opioid receptor balance model, both excessive and deficient μ-receptor activity may negatively influence social behavior, and accordingly both opioid agonist and opioid antagonist treatment may be able to improve social functioning, depending on an individual’s opioid tone before treatment. Our case report is consistent with these hypotheses, and given the extensive unmet medical needs in individuals with autism spectrum disorders, randomized controlled trial appears warranted.

Maternal smoking during pregnancy and children's mental health at age 22 years: Results of a birth cohort study

BACKGROUND

Early exposures such as maternal smoking can be associated mental disorders. We aimed to analyze the association between maternal smoking during pregnancy (MSDP), generalized anxiety disorder (GAD), and depression in the 1993 birth cohort (Pelotas, Brazil).

METHODS

Data on maternal smoking were collected in the perinatal study, while information on GAD and depression was collected at age 22 years using the Mini International Neuropsychiatric Interview (MINI). Information on maternal mental health, the mediator, was collected at the 11-year follow-up. Simple and multiple logistic regressions were used to assess the association between exposure, outcomes, and analysis of negative controls.

RESULTS

3,781 participants presented complete data. The incidence of GAD was 10.4%, depression 2.9%, and smoking during pregnancy 32.6%. The children of mothers who smoked had a 45% higher chance of developing GAD at age 22 years (OR 1.45; 95%CI 1.18; 1.80) and 75% higher chance of depression (OR 1.75; 95%CI 1.18; 2.59). Also, the higher the number of cigarettes smoked. the higher was the chance for the development of GAD. Paternal smoking was not associated with the outcomes. The mother's mental health accounted for 18.2% of the association between maternal smoking and GAD, and for 13.4% for maternal smoking and depression.

LIMITATIONS

Data for smoking during pregnancy were collected through a self-report. Residual confusion due to important variables cannot be ruled out.

CONCLUSIONS

MSDP was associated with the mental health of children in early adulthood. However, a small part of the effect found was mediated by the mother's mental health.

Proteomic Analysis of Plasma Markers in Patients Maintained on Antipsychotics: Comparison to Patients Off Antipsychotics and Normal Controls

BACKGROUND

Schizophrenia (SZ) and bipolar disorder (BD) share many features: overlap in mood and psychotic symptoms, common genetic predisposition, treatment with antipsychotics (APs), and similar metabolic comorbidities. The pathophysiology of both is still not well defined, and no biomarkers can be used clinically for diagnosis and management. This study aimed to assess the plasma proteomics profile of patients with SZ and BD maintained on APs compared to those who had been off APs for 6 months and to healthy controls (HCs).

METHODS

We analyzed the data using functional enrichment, random forest modeling to identify potential biomarkers, and multivariate regression for the associations with metabolic abnormalities.

RESULTS

We identified several proteins known to play roles in the differentiation of the nervous system like NTRK2, CNTN1, ROBO2, and PLXNC1, which were downregulated in AP-free SZ and BD patients but were "normalized" in those on APs. Other proteins (like NCAM1 and TNFRSF17) were "normal" in AP-free patients but downregulated in patients on APs, suggesting that these changes are related to medication's effects. We found significant enrichment of proteins involved in neuronal plasticity, mainly in SZ patients on APs. Most of the proteins associated with metabolic abnormalities were more related to APs use than having SZ or BD. The biomarkers identification showed specific and sensitive results for schizophrenia, where two proteins (PRL and MRC2) produced adequate results.

CONCLUSIONS

Our results confirmed the utility of blood samples to identify protein signatures and mechanisms involved in the pathophysiology and treatment of SZ and BD.

Transdiagnostic Cognitive-Behavioral Therapy for Depression and Anxiety Disorders in Cardiovascular Disease Patients: Results From the CHAMPS Pilot-Feasibility Trial

OBJECTIVE

The aim of the Cardiovascular Health in Anxiety and Mood Problems Study (CHAMPS) is to pilot the Unified Protocol (UP) for the transdiagnostic treatment of depression and anxiety disorders in patients recently hospitalized for cardiovascular diseases (CVDs) and evaluate the feasibility.

METHODS

The present study is a controlled, block randomized pragmatic pilot-feasibility trial incorporating qualitative interview data, comparing UP (n = 9) with enhanced usual care (EUC, n = 10). Eligible trial participants had a recent CVD-cause admission and were above the severity threshold for depression or anxiety denoted by Patient Health Questionnaire (PHQ-9) total scores ≥10 and/or Generalized Anxiety Disorder (GAD-7) total scores ≥7 respectively on two occasions, and met criteria for one or more depression or anxiety disorders determined by structured clinical interview. Study outcomes were analyzed as intention-to-treat using linear mixed models and qualitative interview data were analyzed with content analysis.

RESULTS

Quantitative and qualitative measured indicated acceptability of the transdiagnostic CBT intervention for CVD patients with depression or anxiety disorders. Satisfaction with UP was comparable to antidepressant therapy and higher than general physician counseling. However, there were difficulties recruiting participants with current disorders and distress on two occasions. The UP was associated with a reduction in total number of disorders determined by blinded raters. Linear mixed models indicated that a significantly greater reduction in anxiety symptoms was evident in the UP group by comparison to the EUC group (GAD-7, p between groups = 0.011; Overall Anxiety Severity and Impairment Scale, p between groups = 0.013). Results favored the UP group by comparison to EUC for change over 6 months on measures of physical quality of life and harmful alcohol use. There was no difference between the two groups on changes in depression symptoms (PHQ-9), stress, metacognitive worry beliefs, physical activity, or adherence.

DISCUSSION

In conclusion, this feasibility trial indicates acceptability of transdiagnostic CBT intervention for CVD patients with depression or anxiety disorders that is tempered by difficulties with recruitment. Larger trials are required to clarify the efficacy of transdiagnostic depression and anxiety disorder CBT in populations with CVDs and depressive or anxiety disorders.

Long-term safety of the tafenoquine antimalarial chemoprophylaxis regimen: A 12-month, randomized, double-blind, placebo-controlled trial

BACKGROUND

Tafenoquine is a long-acting 8-aminoquinoline approved for antimalarial prophylaxis for ≤6 months. Additional data is needed to establish the drug's longer-term safety profile, including potential ophthalmic or neuropsychiatric effects.

METHOD

This was a randomized, double-blind, placebo-controlled trial in 600 healthy adults. Eligible subjects were randomized 1:1 to receive tafenoquine 200 mg weekly (antimalarial prophylactic regimen) or placebo for 52 weeks. Scheduled safety visits occurred at Weeks 4, 12, 24, 52 (dosing completed), and 64 (final follow-up). Safety assessments included ophthalmic changes, general and neuropsychiatric adverse events (AEs), and laboratory value changes.

RESULTS

The percentage of subjects with a protocol-defined Serious Ophthalmic Safety Event was lower in the Tafenoquine Group (18.2%) versus the Placebo Group (19%, p = 0.308). There was no significant difference between the percentages of subjects with at least one AE in the Tafenoquine Group (91.0%) versus Placebo (89.9%, p = 0.65). Common AEs seen at a significantly higher incidence for tafenoquine included reversible cornea verticillata (54.5%) and nausea (13.0%), leading to 0.0% and 0.7% discontinuations. Psychiatric AEs occurred at similar percentages in both study groups. Reversible changes in hemoglobin, methemoglobin, creatinine, and blood urea nitrogen (BUN) were noted.

CONCLUSIONS

This study supports the safety of extended 52-week tafenoquine prophylaxis. CLINICAL TRIAL REGISTRATION NUMBER/CLINICALTRIALS.

Understanding the Error in Psychopathology: Notable Intraindividual Differences in Neural Variability of Performance Monitoring

BACKGROUND

Abnormal performance monitoring is a possible transdiagnostic marker of psychopathology. Research on neural indices of performance monitoring, including the error-related negativity (ERN), typically examines group and interindividual (between-person) differences in mean/average scores. Intraindividual (within-person) variability in activity captures the capacity to dynamically adjust from moment to moment, and excessive variability appears maladaptive. Intraindividual variability in ERN represents a unique and largely unexamined dimension that might impact functioning. We tested whether psychopathology group differences (major depressive disorder [MDD], generalized anxiety disorder [GAD], obsessive-compulsive disorder [OCD]) or corresponding psychiatric symptoms account for intraindividual variability in single-trial ERN scores.

METHODS

High-density electroencephalogram (Electrical Geodesics, Inc.) was recorded during a semantic flanker task in 51 participants with MDD, 44 participants with GAD, 31 participants with OCD, and 56 psychiatrically-healthy participants. Mean ERN amplitude was scored 0-125ms following participant response across four fronto-central sites. Multilevel location-scale models were used to simultaneously examine interindividual and intraindividual differences in ERN.

RESULTS

Analyses indicated considerable intraindividual variability in ERN that was common across groups. However, we did not find strong evidence to support relationships between ERN and psychopathology groups or transdiagnostic symptoms.

CONCLUSIONS

These findings point to important methodological implications for studies of performance monitoring in healthy and clinical populations-the common assumption of fixed intraindividual variability (i.e., residual variance) may be inappropriate for ERN studies. Implementation of multilevel location-scale models in future research can leverage between-person differences in intraindividual variability in performance monitoring to gain a rich understanding of trial-to-trial performance monitoring dynamics.

Treating co-morbid insomnia and social anxiety disorder with sequential CBT protocols: a single-case experimental study

BACKGROUND

Although insomnia disorder and social anxiety disorder are among the most prevalent psychiatric disorders, no studies have yet evaluated the use of sequential evidence-based treatment protocols in the population with co-morbid social anxiety disorder and insomnia disorder.

AIMS

This study aimed to investigate the effects of sequential treatments on co-morbid insomnia disorder and social anxiety disorder. As depression is a common co-morbid syndrome for both insomnia and social anxiety, a secondary aim was to examine depressive symptoms.

METHOD

A single-case repeated crossover AB design was used. Ten participants between 18 and 59 years of age with co-morbid DSM-5 diagnoses of insomnia disorder and social anxiety disorder received sequential treatments with cognitive behavioural therapy (CBT). Seven participants completed the treatment course. The primary outcomes were symptoms of insomnia and social anxiety, and the secondary outcome was symptoms of depression.

RESULTS

The effects of CBT on people with co-morbid social anxiety disorder and insomnia disorder were mixed. The majority of participants improved their sleep quality and lessened symptoms of social anxiety and depression. However, participants differed in their degree of improvement concerning all three disorders.

CONCLUSIONS

Sequential CBT treatments are potentially effective at decreasing symptoms of social anxiety and insomnia for people with co-morbid social anxiety disorder and insomnia disorder. The variation in outcome across participants makes firm conclusions about the treatment efficacy difficult to draw.

Adults referred to a national ADHD clinic in Iceland: clinical characteristics and follow-up status

OBJECTIVE

Evaluate adults referred to a national ADHD clinic, by comparing those diagnosed with those who were not, and those who screened negative and to evaluate changes among those diagnosed at follow-up.

METHOD

Data obtained from 531 patients' medical records (49.7% males). One hundred thirty-six screened negative, 395 positive and 305 met diagnostic criteria for ADHD. Eighty-three of them were contacted by phone at follow-up.

RESULTS

ADHD diagnosis was associated with lower educational status and more concerns expressed by parents and teachers during childhood. Participants not diagnosed with ADHD more often met diagnostic criteria for dysthymia, agoraphobia and generalized anxiety, and were more likely to be diagnosed with two or more comorbid disorders. At follow-up, all reported a significant reduction of ADHD symptoms, irrespective of medication, but the medicated participants reported fewer symptoms of inattention and better functioning in daily life.

CONCLUSION

Adults referred to ADHD clinics may have multiple mental health problems, regardless of whether they receive ADHD diagnosis or not. This could have implications for differential diagnoses of ADHD in adults and emphasises the need to have appropriate treatment available for both groups. Psychoeducation about ADHD may be very helpful in decreasing anxiety and ADHD symptoms.

Symptoms of anxiety/depression during the COVID-19 pandemic and associated lockdown in the community: longitudinal data from the TEMPO cohort in France

BACKGROUND

To cope with the COVID-19 pandemic, social distancing restrictions where implemented in France, which could have led to social isolation. This is expected to have affected the mental health situation, including increasing risk of symptoms of anxiety and depression in the general population. Persons with prior mental health difficulties could be an especially vulnerable group, however, few studies have tested this empirically considering preexisting mental health difficulties. We examine the association between preexisting symptoms of anxiety/depression and anxiety/depression during lockdown due to the COVID-19 pandemic in a longitudinal community sample.

METHODS

A longitudinal follow-up during lockdown (data collection March-June 2020) was implemented among participants of the TEMPO cohort. Prior knowledge of anxiety/depression was included from prior waves of data collection. Generalized estimation equations models were used to estimate the association between preexisting symptoms of anxiety/depression and symptoms of anxiety/depression during lockdown among 662 mid-aged individuals.

RESULTS

Individuals with symptoms of anxiety/depression measured prior to lockdown had 6.73 higher odds [95% CI = 4.45-10.17] of symptoms of anxiety/depression during lockdown. Additionally, the likelihood of symptoms of anxiety/depression during lockdown was elevated among women (OR = 2.07 [95% CI = 1.32-3.25]), subjects with low household income (OR = 2.28 [1.29-4.01]) and persons who reported being lonely (OR = 3.94 [95% CI = 2.47-6.28]).

CONCLUSIONS

Our study underlines the role of preexisting symptoms of anxiety/depression as a vulnerability factor of anxiety/depression during lockdown. Interventions focusing on individuals with mental health difficulties as well as people feeling lonely should be considered, to reduce the psychological impact of the COVID-19 pandemic.

Clinical Neuropsychological Evaluation in Older Adults With Major Depressive Disorder

PURPOSE OF THE REVIEW

Older adults with major depressive disorder are particularly vulnerable to MDD-associated adverse cognitive effects including slowed processing speed, decreased attention, and executive dysfunction. The purpose of this review is to describe the approach to a clinical neuropsychological evaluation in older adults with MDD. Specifically, this review compares and contrasts neurocognitive screening and clinical neuropsychological evaluation procedures and details the multiple components of the clinical neuropsychological evaluation.

RECENT FINDINGS

Research has shown that neurocognitive screening serves a useful purpose to provide an acute and rapid assessment of global cognitive function; however, it has limited sensitivity and specificity. The clinical neuropsychological evaluation process is multifaceted and encompasses a review of available medical records, neurobehavioral status and diagnostic interview, comprehensive cognitive and clinical assessment, examination of inclusion and diversity factors as well as symptom and performance validity, and therapeutic feedback. As such, the evaluation provides invaluable information on multiple cognitive functions, establishes brain and behavior relationships, clarifies neuropsychiatric diagnoses, and can inform the etiology of cognitive impairment. Clinical neuropsychological evaluation plays a unique and critical role in integrated healthcare for older adults with MDD. Indeed, the evaluation can serve as a nexus to synthesize information across healthcare providers in order to maximize measurement-based care that can optimize personalized medicine and overall health outcomes.

Nonsuicidal self-injury in undergraduate students with major depressive disorder: The role of psychosocial factors

BACKGROUND

Nonsuicidal self-injury (NSSI) is related to childhood abuse, family relationships, interpersonal relationships, personality, but the interaction between them is still unclear, and how they interact in major depressive disorder (MDD).

METHODS

Collected data from 444 undergraduate degree students with MDD participated. Used the Eysenck Personality Questionnaire, Childhood Trauma Questionnaire, Interpersonal Relationship Comprehensive Diagnostic Scale, and Family Assessment Device to assess the patients' psychosocial factors. NSSI behavior was assessed through interviews. Use the Chi-square test, Wilcoxon rank-sum test, Kruskal-Wallis H-test, Distance Correlation, Structural Equation Mode for data analysis.

RESULTS

Overall, 34.2% of patients with MDD had a history of NSSI. MDD patients with a history of NSSI had significant differences in psychoticism, neuroticism, emotional abuse, physical abuse, sexual abuse, emotional neglect, troubles in conversation, ability to make friends and family roles. Among these factors, psychoticism was most related to NSSI, and child abuse, interpersonal relationships and family roles played a variety of roles in mediating the relationship with NSSI.

CONCLUSIONS

Psychosocial factors affect the occurrence of NSSI through chain intermediary effects.

Intimate partner violence against women and child maltreatment in a Brazilian birth cohort study: co-occurrence and shared risk factors

BACKGROUND

Intimate partner violence (IPV) against women and child maltreatment (CM) are major public health problems and human rights issues and may have shared causes. However, their overlap is understudied. We investigated the prevalence of IPV and CM, their co-occurrence in households and possible shared risk factors, in the general population of a Brazilian urban setting.

METHODS

Prospective population-based birth cohort, including over 3500 mother-child dyads with maternal reports on both IPV and CM when children were 4 years old. Eleven neighbourhood, family and parental risk factors were measured between birth and age 4 years. Bivariate and multivariate Poisson regression models with robust variance were used to test which potential risk factors were associated with IPV, CM and their co-occurrence.

RESULTS

The prevalence of any IPV and CM were 22.8% and 10.9%, respectively; the co-occurrence of both types of violence was 5%. Multivariate analyses showed that the overlap of IPV and CM was strongly associated with neighbourhood violence, absence of the child's biological father, paternal antisocial behaviour in general and a mother-partner relationship characterised by high levels of criticism, maternal depression and younger maternal age. A concentration of many risk factors among 10% of the population was associated with a sixfold increase in risk for overlapping IPV and CM compared with households with no risk factors.

CONCLUSION

IPV and CM share important risk factors in the family and neighbourhood environments and are particularly common in households with multiple social disadvantages and family difficulties. Integrated preventive interventions are needed.

Validation of the 7-item Generalized Anxiety Disorder scale (GAD-7) as a screening tool for anxiety among pregnant Chinese women

BACKGROUND

Anxiety is common during pregnancy. The 7-item Generalized Anxiety Disorder scale (GAD-7) is a self-rating scale for detecting anxiety and has been validated in various populations, but it has not been validated in pregnant Chinese women. The objective of this study was to validate the GAD-7 as a screening tool to detect anxiety during pregnancy among Chinese women.

METHODS

The GAD-7 and the anxiety subscale of the Hospital Anxiety and Depression scale (HADS-A) were administered to 140 pregnant Chinese women to evaluate the Cronbach's alpha and the criterion-related validity. Additionally, a diagnostic study (n=170) was conducted by using the Mini International Neuropsychiatric Interview (MINI) as a gold standard to examine the screening performance of the GAD-7. We calculated the sensitivity, specificity, and area under the curve (AUC) by receiver operating characteristic (ROC) analysis.

RESULTS

Cronbach's alpha for the GAD-7 was 0.84. The Pearson correlation coefficient between GAD-7 and HADS-A scores was 0.66 (P<0.01). At the maximum Youden Index of 0.53, the optimal cutoff score for the GAD-7 among pregnant women was 7, and an AUC of 0.83, a sensitivity of 96.8%, and a specificity of 56.1% were obtained.

LIMITATION

The majority of the participants were in the first trimester, and thus, the findings cannot be generalized to all pregnant women.

CONCLUSIONS

The GAD-7 is a suitable screening instrument for detecting antenatal anxiety in mainland China. Further validation is warranted in women in different trimesters of pregnancy.

Association Between Obsessive-Compulsive Symptom Dimensions in Mothers and Psychopathology in Their Children

Background: The non-clinical presentation of obsessive-compulsive symptoms (OCS) in women may impact not only their daily lives and well-being but also increase the risk for emotional and behavioral problems in their children. This study aims to investigate the OCS dimension distribution in a large sample of mothers from a cohort of school age children and the association between these OCS dimensions with their own psychopathology, and with the presence of OCS and other psychopathology in their children. Method: Our final sample consisted of 2,511 mother-children dyads recruited from the elementary schools of two large cities. Throughout multiple regression analysis, we examined the correlations between demographic and clinical variables of mothers assessed by the Mini International Psychiatric Interview (MINI) and the Dimensional Yale-Brown Obsessive-Compulsive Scale-Short Version (DY-BOCS-SV) with children's psychopathology status reported by the Child Behavior Checklist (CBCL). Results: The overall prevalence of mothers who reported experiencing at least one OCS was 40% (N = 1,004). "Aggression/violence" was the most frequent symptom dimension (32.2%), followed by the "symmetry/ordering" (16.4%) and the "sexual/religious" dimensions (13.8%). There was a significant correlation between the presence of OCS and maternal psychopathology in general (p < 0.001, r = 0.397). Not only the presence but also the severity of the mother's OCS were strongly correlated to the total (p < 0.001), internalizing (p < 0.001), externalizing (p < 0.001), and OCS subscale scores (p < 0.001) on the CBCL. Conclusion: OCS dimensions are highly prevalent in women. Presence and severity of maternal OCS are related to children's psychopathology and behavioral problems.

Manualised cognitive-behavioural therapy in treating depression in advanced cancer: the CanTalk RCT

BACKGROUND

With a prevalence of up to 16.5%, depression is one of the commonest mental disorders in people with advanced cancer. Depression reduces the quality of life (QoL) of patients and those close to them. The National Institute for Health and Care Excellence (NICE) guidelines recommend treating depression using antidepressants and/or psychological treatments, such as cognitive-behavioural therapy (CBT). Although CBT has been shown to be effective for people with cancer, it is unclear whether or not this is the case for people with advanced cancer and depression.

OBJECTIVES

To assess the clinical effectiveness and cost-effectiveness of treatment as usual (TAU) plus manualised CBT, delivered by high-level Improving Access to Psychological Therapy (IAPT) practitioners, versus TAU for people with advanced cancer and depression, measured at baseline, 6, 12, 18 and 24 weeks.

DESIGN

Parallel-group, single-blind, randomised trial, stratified by whether or not an antidepressant was prescribed, comparing TAU with CBT plus TAU.

SETTING

Recruitment took place in oncology, hospice and primary care settings. CBT was delivered in IAPT centres or/and over the telephone.

PARTICIPANTS

Patients (N = 230; n = 115 in each arm) with advanced cancer and depression. Inclusion criteria were a diagnosis of cancer not amenable to cure, a DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) diagnosis of depressive disorder using the Mini-International Neuropsychiatric Interview, a sufficient understanding of English and eligibility for treatment in an IAPT centre. Exclusion criteria were an estimated survival of < 4 months, being at high risk of suicide and receiving, or having received in the last 2 months, a psychological intervention recommended by NICE for treating depression.

INTERVENTIONS

(1) Up to 12 sessions of manualised individual CBT plus TAU delivered within 16 weeks and (2) TAU.

OUTCOME MEASURES

The primary outcome was the Beck Depression Inventory, version 2 (BDI-II) score at 6, 12, 18 and 24 weeks. Secondary outcomes included scores on the Patient Health Questionnaire-9, the Eastern Cooperative Oncology Group Performance Status, satisfaction with care, EuroQol-5 Dimensions and the Client Services Receipt Inventory, at 12 and 24 weeks.

RESULTS

A total of 80% of treatments (185/230) were analysed: CBT (plus TAU) (n = 93) and TAU (n = 92) for the BDI-II score at all time points using multilevel modelling. CBT was not clinically effective [treatment effect -0.84, 95% confidence interval (CI) -2.76 to 1.08; p = 0.39], nor was there any benefit for other measures. A subgroup analysis of those widowed, divorced or separated showed a significant effect of CBT on the BDI-II (treatment effect -7.21, 95% CI -11.15 to -3.28; p < 0.001). Economic analysis revealed that CBT has higher costs but produces more quality-adjusted life-years (QALYs) than TAU. The mean service costs for participants (not including the costs of the interventions) were similar across the two groups. There were no differences in EQ-5D median scores at baseline, nor was there any advantage of CBT over TAU at 12 weeks or 24 weeks. There was no statistically significant improvement in QALYs at 24 weeks.

LIMITATIONS

Although all participants satisfied a diagnosis of depression, for some, this was of less than moderate severity at baseline, which could have attenuated treatment effects. Only 64% (74/115) took up CBT, comparable to the general uptake through IAPT.

CONCLUSIONS

Cognitive-behavioural therapy (delivered through IAPT) does not achieve any clinical benefit in advanced cancer patients with depression. The benefit of CBT for people widowed, divorced or separated is consistent with other studies. Alternative treatment options for people with advanced cancer warrant evaluation. Screening and referring those widowed, divorced or separated to IAPT for CBT may be beneficial. Whether or not improvements in this subgroup are due to non-specific therapeutic effects needs investigation.

Efficacy and safety of TS-121, a novel vasopressin V1B receptor antagonist, as adjunctive treatment for patients with major depressive disorder: A randomized, double-blind, placebo-controlled study

Vasopressin 1B (V_1B) receptor has a pivotal role in the regulation of the hypothalamus-adrenal-pituitary axis, and V_1B receptor antagonists have shown efficacy in a number of preclinical models of depression. The efficacy and safety of, TS-121 (active ingredient: THY1773), a novel V_1B receptor antagonist, was investigated in patients with major depressive disorder (MDD) who had an inadequate response to current antidepressant therapy. In a randomized, double-blind, placebo-controlled phase 2 study, 51 MDD patients (43 of whom completed the study) were randomly assigned to either TS-121 10 mg, 50 mg or placebo for 6 weeks treatment period. The primary endpoint was change from baseline on the Montgomery-Åsberg Depression Rating Scale (MADRS) score at week 6. The study was conducted from Jul 2017 to Dec 2018. The changes from baseline in MADRS score at week 6 (Least Square Mean [95% Confidence interval] were: TS-121 10 mg (-9.0 [-13.9, -4.1]), TS-121 50 mg (-9.0 [-13.4, -4.5]), and placebo (-6.4 [-10.7, -2.2]). TS-121 groups showed greater numerical reductions in MADRS score change from baseline compared to placebo, though these reductions did not achieve statistical significance. Similar trends of numerically greater improvements in TS-121 groups were observed across secondary endpoints. Higher baseline urinary and hair cortisol levels were associated with a greater separation between TS-121 groups and the placebo group in the primary endpoint. These findings, combined with favorable safety and tolerability, warrant further investigation of TS-121 in an adequately powered study in patients with MDD.

Lower cerebrospinal fluid CRH concentration in chronic schizophrenia with negative symptoms

Some patients with schizophrenia have impaired hypothalamic-pituitary-adrenal axis function. However, there is a dearth of studies focusing on corticotropin-releasing hormone (CRH) levels in the brains of schizophrenia patients, which motivated us to examine whether cerebrospinal fluid (CSF) CRH concentrations are altered in these patients. We also examined the possible correlation of CSF CRH level with clinical variables such as schizophrenia symptoms and antipsychotic medication. The study population comprised 20 patients with a diagnosis of schizophrenia according to DSM-5 criteria and 25 healthy controls, who underwent lumbar puncture. Most of the patients were treated with antipsychotic drugs and their doses were converted to chlorpromazine (CP) equivalent values. CSF CRH concentrations were measured by an enzyme immunoassay. Symptom severity was assessed using the Positive and Negative Syndrome Scale (PANSS). There was a significantly lower CSF CRH concentration in the patients than in the controls (Mann-Whitney U test: p = 0.014). A significantly negative correlation of CSF CRH levels with PANSS negative scores was found in the patients (Spearman's: ρ = -0.58, p = 0.007). However, CSF CRH concentrations were not significantly correlated with the PANSS total (ρ = -0.035, p = 0.89), positive (ρ = 0.25, p = 0.30), or general psychopathology (ρ = 0.13, p = 0.59) scores. No significant correlation was found with CP equivalent values (ρ = 0.00, p = 1.00). In conclusion, we found that the patients with schizophrenia had lower CSF CRH concentrations compared to the controls and that the lower CSF CRH was associated with negative symptoms of the illness. Further studies in a larger sample and in drug-free patients are warranted.

Self-Reported Sleep and Exercise Patterns in Patients with Schizophrenia: a Cross-Sectional Comparative Study

BACKGROUND

Adequate sleep and physical activity have been linked to the overall well-being of both medical and psychiatric patients. Patients with schizophrenia have shown abnormal sleep patterns and decreased physical activity that were linked to their psychopathology and physical health. These phenomena are not studied yet in Arab patients with schizophrenia. The purpose of this study is to study the sleep and exercise patterns in Arab patients with schizophrenia compared with those of healthy controls.

METHOD

A total of 99 patients with schizophrenia and 101 controls were recruited. Arabic versions of sleep, exercise, socio-demographic, and clinical questionnaires were administered as well as the validated scales to measure psychopathology, depression, and suicidality in these participants.

RESULTS

The majority of patients with schizophrenia slept more than 8 h per day and exercised less when compared with controls. Sleep quality was worse in those with higher depression score and higher suicidality scores were seen in patients with lower sleep duration. Multinomial regression showed that patients with schizophrenia have higher odds of sleeping more than 8 h even after controlling for the intake of antipsychotics, age, gender, smoking status, and other confounding factors.

CONCLUSION

Our results showed that Arab patients with schizophrenia are at increased risk of having longer sleep duration with inadequate physical activity, which are correlating with worsening of depressive symptoms and suicidality. Thus, more attention should be paid to the changes in sleep patterns and level of exercise when treating Arab patients with schizophrenia.

Death anxiety and attitude to death in patients with schizophrenia and depression

Attitude to death and death anxiety in patients with severe psychiatric disorders have been studied rarely so far, although this is an existential perspective for each human being and clinically seems to be changed in patients with depression and schizophrenia. Patients with depression (mean age 46.30 ± 13.39; 12 women, 8 men) and schizophrenia (mean age 38.95 ± 1285; 9 women, 11 men), as well as healthy controls, were included in the study. Death anxiety and attitude to death were assessed using the newly developed and currently validated BOFRETTA scale. Attitude to death was significantly worse in the group of patients with schizophrenia, especially in those with prominent negative symptoms. Concerning death anxiety, patients with schizophrenia and also those with depression exhibited higher mean values compared with healthy controls in the same age range. These results suggest that there are specific similarities and differences concerning attitude to death and death anxiety in patients with psychotic and affective disorders. It can be concluded that existential aspects such as death and meaningful life should also be considered within the treatment of patients with severe mental disorders.

Associations of substance use, psychosis, and mortality among people living in precarious housing or homelessness: A longitudinal, community-based study in Vancouver, Canada

BACKGROUND

The "trimorbidity" of substance use disorder and mental and physical illness is associated with living in precarious housing or homelessness. The extent to which substance use increases risk of psychosis and both contribute to mortality needs investigation in longitudinal studies.

METHODS AND FINDINGS

A community-based sample of 437 adults (330 men, mean [SD] age 40.6 [11.2] years) living in Vancouver, Canada, completed baseline assessments between November 2008 and October 2015. Follow-up was monthly for a median 6.3 years (interquartile range 3.1-8.6). Use of tobacco, alcohol, cannabis, cocaine, methamphetamine, and opioids was assessed by interview and urine drug screen; severity of psychosis was also assessed. Mortality (up to November 15, 2018) was assessed from coroner's reports and hospital records. Using data from monthly visits (mean 9.8, SD 3.6) over the first year after study entry, mixed-effects logistic regression analysis examined relationships between risk factors and psychotic features. A past history of psychotic disorder was common (60.9%). Nonprescribed substance use included tobacco (89.0%), alcohol (77.5%), cocaine (73.2%), cannabis (72.8%), opioids (51.0%), and methamphetamine (46.5%). During the same year, 79.3% of participants reported psychotic features at least once. Greater risk was associated with number of days using methamphetamine (adjusted odds ratio [aOR] 1.14, 95% confidence interval [CI] 1.05-1.24, p = 0.001), alcohol (aOR 1.09, 95% CI 1.01-1.18, p = 0.04), and cannabis (aOR 1.08, 95% CI 1.02-1.14, p = 0.008), adjusted for demographic factors and history of past psychotic disorder. Greater exposure to concurrent month trauma was associated with increased odds of psychosis (adjusted model aOR 1.54, 95% CI 1.19-2.00, p = 0.001). There was no evidence for interactions or reverse associations between psychotic features and time-varying risk factors. During 2,481 total person years of observation, 79 participants died (18.1%). Causes of death were physical illness (40.5%), accidental overdose (35.4%), trauma (5.1%), suicide (1.3%), and unknown (17.7%). A multivariable Cox proportional hazard model indicated baseline alcohol dependence (adjusted hazard ratio [aHR] 1.83, 95% CI 1.09-3.07, p = 0.02), and evidence of hepatic fibrosis (aHR 1.81, 95% CI 1.08-3.03, p = 0.02) were risk factors for mortality. Among those under age 55 years, a history of a psychotic disorder was a risk factor for mortality (aHR 2.38, 95% CI 1.03-5.51, p = 0.04, adjusted for alcohol dependence at baseline, human immunodeficiency virus [HIV], and hepatic fibrosis). The primary study limitation concerns generalizability: conclusions from a community-based, diagnostically heterogeneous sample may not apply to specific diagnostic groups in a clinical setting. Because one-third of participants grew up in foster care or were adopted, useful family history information was not obtainable.

CONCLUSIONS

In this study, we found methamphetamine, alcohol, and cannabis use were associated with higher risk for psychotic features, as were a past history of psychotic disorder, and experiencing traumatic events. We found that alcohol dependence, hepatic fibrosis, and, only among participants <55 years of age, history of a psychotic disorder were associated with greater risk for mortality. Modifiable risk factors in people living in precarious housing or homelessness can be a focus for interventions.

Structural brain differences between ultra-endurance athletes and sedentary persons

Participation in ultra-endurance events has increased in recent years and requires extreme levels of moderate to vigorous physical activity (MVPA). Moderate levels of MVPA have been associated with increased brain volume but the effects of extreme levels of MVPA on brain volume is unknown. As a result, we sought to compare the brains of those who engage in extremely high levels of MVPA with those who are sedentary using magnetic resonance imaging. We performed whole brain volumetric analyses and voxel-based morphometry on 12 ultra-endurance athletes (1078.75 ± 407.86 min of MVPA/week) and 9 sedentary persons (18.0 ± 56.9 min of MVPA/week). Whole-brain analyses revealed that those who participate in ultra-endurance training have increased grey (p< 0.0001), white (p = 0.031), and total matter volume (p < 0.0001), while regional analyses revealed that ultra-endurance athletes have smaller regional grey matter volume in the right primary sensory and motor cortex, inferior and middle frontal gyrus, and left thalamus. Future research is warranted to determine why ultra-endurance athletes have lower regional volumes in these areas despite having overall increased grey and white matter volumes.

Burden of Depression in Outpatient HIV-Infected adults in Sub-Saharan Africa; Systematic Review and Meta-analysis

Despite the substantial burden of HIV in Africa, and the knowledge that depression causes worse HIV outcomes, the burden of depression in people living with HIV in Africa is unknown. We searched Pubmed and four other databases using key terms: depression, Africa, HIV, and prevalence from 2008 to 2018. We summarized depression prevalence by country. We estimated the burden of depression using our prevalence data and 2018 UNAIDS HIV estimates. Our search yielded 70 articles across 16 African countries. The overall prevalence of major depression in those HIV-infected using a diagnostic interview was 15.3% (95% CI 12.5-17.1%). We estimate that 3.63 million (99.7% CI 3.15-4.19 million) individuals with HIV in Sub-Saharan Africa have major depression and provide country-level estimates. We estimate that 1.57 million (99.7% CI 1.37-1.82 million) DALYs are lost among people with depression and HIV in Sub-Saharan Africa. There is a significant burden of depression in Africans with HIV. Further work to screen for and treat depression in Sub-Saharan Africa is needed to improve HIV outcomes and achieve the 90-90-90 UNAIDS goals.

Depression and the Effect of Sertraline on Inflammatory Biomarkers in Patients with Nondialysis CKD

Background

Inflammatory biomarkers are elevated in patients with CKD and associated with poor outcomes. Major depressive disorder (MDD) is prevalent in CKD and associated with inflammation. No studies investigated the effect of MDD treatment on plasma inflammatory biomarkers in patients with nondialysis CKD.

Methods

In a prespecified analysis of the randomized, double-blind CKD Antidepressant Sertraline Trial, we investigated whether treatment with sertraline versus placebo or response to treatment would affect plasma levels of albumin, prealbumin, IL-6, and high-sensitivity C-reactive protein (hsCRP), measured at baseline and after 12 weeks of treatment. We also explored whether somatic versus nonsomatic depressive symptoms, measured using the Quick Inventory of Depressive Symptomatology, and quality-of-life subscales, measured using the Kidney Disease Quality of Life Short Form, were associated with baseline levels of these inflammatory biomarkers.

Results

Of the 193 participants, mean age was 58.4 (SD 13) years and 58% were black, 42% were white, and 18% were Hispanic. Higher baseline hsCRP correlated with somatic depressive symptoms (r=0.21; P=0.01), fatigue (r=0.22; P=0.005), and poorer physical functioning (r=−0.26; P=0.001). There was no change in hsCRP in the sertraline group. hsCRP increased in placebo nonresponders from baseline (median, 3.7 mg/L; interquartile range [IQR], 1.7–10.0 mg/L) to exit (median, 4.9 mg/L; IQR, 1.8–8.8 mg/L; P=0.01). The change from baseline to exit differed between placebo responders (median, −0.4 mg/L; IQR, −9.3 to 0.2 mg/L) and nonresponders (median, 0.8 mg/L; IQR, −0.1 to 3.9 mg/L; P=0.008). There were no differences in changes in albumin, prealbumin, or IL-6 from baseline in any group.

Conclusions

Among patients with CKD and MDD, hsCRP correlated with somatic symptoms of depression and fatigue, but not with nonsomatic symptoms. Sertraline treatment was not associated with a longitudinal change in hsCRP from baseline regardless of treatment effect on depressive symptoms, but those who failed to respond to placebo had an increase in hsCRP over time. This area deserves further investigation.

Impulsive and premeditated aggression in male offenders with antisocial personality disorder

INTRODUCTION

Aggression is a clinical symptom of various psychiatric disorders that can be conceptualised as a physical act towards another person with the intent to cause harm. In antisocial personality disorder (ASPD), aggression is a frequent manifestation that differently compromise therapeutic and prognostic goals according to its impulsive or premeditated categorisation. ASPD is characterised by high levels of impulsivity, psychopathic traits, and a high prevalence of co-morbid substance use disorders (SUDs). Aggression in ASPD patients may determine long and recurrent imprisonment thus representing a challenge clinicians and legal experts face.

OBJECTIVES

Our aims were to characterise impulsive and premeditated aggression in male ASPD offenders as well as to determine the potential role of SUDs, impulsivity, and psychopathic traits as predictors.

MATERIALS AND METHODS

In this cross-sectional study we evaluated a sample of ASPD offenders with a battery of clinical and psychometric, standardised instruments: the Psychopathy Checklist-Revised (PCL-R), the European Version of the Addiction Severity Index (EuropASI), the Barratt Impulsivity Scale Version 11 (BIS-11), and the Impulsive/Premeditated Aggression Scale (IPAS).

RESULTS

We used a total sample of 134 offenders, all of whom were male. ASPD patients (n = 96) had a 71.9% prevalence of impulsive aggression and a 28.1% prevalence of premeditated aggression. ASPD patients with impulsive aggression had significantly lower scores of total PCL-R (p<0.01) factor 1 and interpersonal facet 1 (p<0.05), compared with ASPD patients with premeditated aggression. ASPD patients with impulsive aggression and ASPD patients with premeditated aggression had comparable BIS-11 mean scores, and exhibited an equal prevalence of SUDs. The interpersonal facet 1of the PCL-R predicted the aggression type (p<0.05) in ASPD patients, and the exponential beta value for facet 1 was 1.42 (CI = 1.03; 1.95).

CONCLUSIONS

The aggression type that is associated with ASPD is mainly impulsive in nature. ASPD patients who have higher scores of psychopathic traits have a lower probability of exhibiting impulsive aggression and a higher probability of exhibiting premeditated aggression. Although ASPD patients have high levels of impulsivity and a high frequency of SUDs, these two variables were not predictors of the aggression type.

The ease and sureness of a decision: evidence accumulation of conflict and uncertainty

The likelihood of an outcome (uncertainty or sureness) and the similarity between choices (conflict or ease of a decision) are often critical to decision-making. We often ask ourselves: how likely are we to win or lose? And how different is this option's likelihood from the other? Uncertainty is a characteristic of the stimulus and conflict between stimuli, but these dissociable processes are often confounded. Here, applying a novel hierarchical drift diffusion approach, we study their interaction using a sequential learning task in healthy volunteers and pathological groups characterized by compulsive behaviours, by posing it as an evidence accumulation problem. The variables, Conflict (difficult or easy; difference between reward probabilities of the stimuli) and Uncertainty (low, medium or high; inverse U-shaped probability-uncertainty function) were then used to extract threshold ('a', amount of evidence accumulated before making a decision) and drift rate ('v', information processing speed) parameters. Critically, when a decision was both difficult (high conflict) and uncertain, relative to other conditions, healthy volunteers unexpectedly accumulated less evidence with lower decision thresholds and accuracy rates at chance levels. In contrast, patients with obsessive-compulsive disorder had slower processing speeds during these difficult uncertain decisions; yet, despite this more cautious approach, performed suboptimally with poorer accuracy relative to healthy volunteers below that of chance level. Thus, faced with a difficult uncertain decision, healthy controls are capable of rapid possibly random decisions, displaying almost a willingness to 'walk away', whereas those with obsessive compulsive disorder become more deliberative and cautious but despite appearing to learn the differential contingencies, still perform poorly. These observations might underlie disordered behaviours characterized by pathological uncertainty or doubt despite compulsive checking with impaired performance. In contrast, alcohol-dependent subjects show a different pattern relative to healthy controls with difficulties in adjusting their behavioural patterns with slower drift rates or processing speed despite decisions being easy or low conflict. We emphasize the multidimensional nature of compulsive behaviours and the utility of computational models in detecting subtle underlying processes relative to behavioural measures. These observations have implications for targeted behavioural interventions for specific cognitive impairments across psychiatric disorders.

Childhood overweight and obesity and the risk of depression across the lifespan

BACKGROUND

Obesity has been longitudinally associated with depression but only few studies take a life course approach. This longitudinal study investigates whether being overweight or obese at age 8 and 13 years is associated with depressive symptoms more than 60 years later and whether this association is independent of late-life body mass index (BMI). We also investigated the association of being overweight/obese at age 8 or 13 years with ever having major depressive disorder (lifetime MDD).

METHOD

This analysis is based on a sub-sample of 889 AGES-Reykjavik participants with measured BMI data from early life. Late-life depressive symptoms were measured with the Geriatric Depression Scale (GDS) and lifetime MDD was assessed at late-life using the Mini International Neuropsychiatric Interview. Logistic regression analysis was used to estimate the relationships between BMI (continuous and categorical) at age 8 or 13 years, and late-life depressive symptoms (measured as GDS ≥ 5) or lifetime MDD, adjusted for sex, education, physical activity, smoking status and alcohol use. In a separate model, additional adjustments were made for late-life BMI.

RESULTS

One hundred and one subjects (11%) had depressive symptoms at late-life (GDS ≥ 5), and 39 subjects (4.4%) had lifetime MDD. Being overweight or obese at age 8 or 13 years was not associated with higher depressive symptoms during late-life, irrespective of late-life BMI. Being overweight or obese at age 8 years, but not age 13 years was associated with an increased risk of lifetime MDD (Odds Ratio (OR) (95% confidence interval [CI]) for age 8 = 4.03[1.16-13.96]P = 0.03 and age 13 = 2.65[0.69-10.26] P = 0.16, respectively).

CONCLUSION

Being overweight in childhood was associated with increased odds of lifetime MDD, although the magnitude of the risk is uncertain given the small numbers of participants with lifetime MDD. No clear association was observed between childhood and adolescent overweight/obesity and late-life depressive symptoms irrespective of late life BMI.

Identifying the Internalizing Disorder Clusters Among Recently Hospitalized Cardiovascular Disease Patients: A Receiver Operating Characteristics Study

Depression and anxiety disorders are common among cardiovascular disease (CVD) populations, leading several cardiology societies to recommend routine screening to streamline psychological interventions. However, it remains poorly understood whether routine screening in CVD populations identifies the broader groups of disorders that cluster together within individuals, known as anxious-misery and fear. This study examines the screening utility of four anxiety and depression questionnaires to identify the two internalizing disorder clusters; anxious-misery and fear. Patients with a recent hospital admission for CVD (n = 85, 69.4% males) underwent a structured clinical interview with the MINI International Neuropsychiatric Interview. The participants also completed the Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder (GAD-7) scale, Overall Anxiety Severity Impairment Scale (OASIS), and the stress subscale of the Depression Anxiety Stress Scale (DASS). The PHQ-9 and the GAD-7 yielded appropriate screening properties to detect three different iterations of the anxious-misery cluster (sensitivity >80.95% and specificity >82.81%). The GAD-7 was the only instrument to display favorable screening properties to detect a fear cluster omitting post-traumatic stress disorder (PTSD) but including obsessive-compulsive disorder (OCD; sensitivity 81.25%, specificity 76.81%). These findings indicate that the PHQ-9 and GAD-7 could be implemented to reliably screen for anxious-misery disorders among CVD in-patients, however, the receiver operating characteristics (ROC) to detect fear disorders were contingent on the placement of PTSD and OCD within clusters. The findings are discussed in relation to routine screening guidelines in CVD populations and contemporary understandings of the internalizing disorders.

Anxiety, Prenatal Attachment, and Depressive Symptoms in Women with Diabetes in Pregnancy

The purpose of this study was to evaluate the relationship between anxiety, prenatal attachment, and depressive symptoms among women with diabetes in pregnancy. Participants were 131 consecutive pregnant women between the ages of 20 and 45 with a diagnosis of gestational or pregestational type 1 or type 2 diabetes. Data on previous psychiatric symptoms were obtained from the Anamnestic and Social Questionnaire and the Mini-International Neuropsychiatric Interview (MINI). Information on prenatal attachment was collected using The Prenatal Attachment Inventory (PAI), and The Edinburgh Postnatal Depression Scale (EPDS) assessed depressive symptoms in the third trimester of pregnancy (at a mean of 25 weeks). Results demonstrated that in women affected by diabetes in pregnancy, two facets of prenatal attachment (anticipation, interaction) were negatively correlated with depressive symptoms, and a history of anxiety, assessed with the MINI, moderated the relation between the prenatal attachment interaction factor and depressive symptoms during pregnancy.

Clinical Differences Between Single and Multiple Suicide Attempters, Suicide Ideators, and Non-suicidal Inpatients

Single suicide attempters (SSAs) and multiple suicide attempters (MSAs) represent distinct subgroups of individuals with specific risk factors and clinical characteristics. This retrospective study on a sample of 397 adult psychiatric inpatients analyzed the main sociodemographic and clinical differences between SSAs and MSAs and the possible differences between SSAs, MSAs, and psychiatric patients with and without suicidal ideation (SI). Clinical variables collected included psychiatric diagnoses (Mini International Neuropsychiatric Interview), presence of substance use, current suicide risk status (Columbia Suicide Severity Rating Scale), Clinical Global Impression at admission, Global Assessment of Functioning improvement between admission and discharge, age at onset of psychiatric illness, duration of untreated illness in years, number of hospitalizations in psychiatric settings, and lethality of the most severe suicide attempt. A multinomial logistic regression model with groups showed that MSAs had a higher lethality of their last suicide attempt as compared to SSAs. In addition, MSAs had distinct sociodemographic characteristics compared to both SSAs and patients with SI. Although the study was limited by the relatively small sample size and retrospective nature, the present results suggest that identifying MSAs could be useful in predicting suicide risk and designing ad hoc prevention strategies.
