Özer G, Işık İ, Escartín J. Is There Somebody Looking out for Me? A Qualitative Analysis of Bullying Experiences of Individuals Diagnosed with Bipolar Disorder. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2024; 21:137. [PMID: 38397628 PMCID: PMC10887664 DOI: 10.3390/ijerph21020137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 01/23/2024] [Accepted: 01/25/2024] [Indexed: 02/25/2024]
Abstract
According to the World Health Organisation, there are globally 40 million individuals with bipolar disorder (BD), and they experience stigma and discrimination, as many people with mental illness do. Work bullying (WB) is a common organisational problem, deteriorating the well-being and performance of employees and organisations. Although WB experiences have been researched for over three decades, we do not know much about the experiences of this group and what they need to extend their work-life. The current research aims to understand the workplace bullying experiences of individuals with BD and factors that may foster or hinder their participation in the labour force. The research methodology was based on in-depth interviews with 19 employees diagnosed with BD. Bullying experiences were mapped onto the Negative Acts Questionnaire. The data were analysed using the deductive qualitative content analysis on MAXQDA. Results showed that individuals with BD were exposed to bullying in work settings. Perceived reasons for the negative behaviours were mainly the undesirable individual characteristics of the bully, prejudices toward bipolar disorder, and already-existing toxic behaviours within the organisation. To reduce bullying, participants suggested that, among others, top management include equal and fair treatment of disadvantaged employees as performance criteria for supervisors and that organisations provide training against bullying, investigate complaints, apply sanctions, and establish an inclusive environment. If organisations set a stable and enduring vision, enhance a common identity for all employees, work on team building, and emphasise team efforts and goals, the organisational environment would be more inclusive, and individuals with BD would have longer work lives.

J Affect Disord 2023; 331:192-199. [PMID: 36948465 DOI: 10.1016/j.jad.2023.03.060] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 03/11/2023] [Accepted: 03/18/2023] [Indexed: 03/24/2023]
Abstract
BACKGROUND Major depressive disorder (MDD), dysthymia disorder (DD) and bipolar disorder (BD) are the most prevalent affective disorders. A nationwide epidemiological investigation of MDD, DD and BP in school-attending children and adolescents was carried out, taking the effect of age, gender and comorbidity into consideration. METHODS A two-stage nationwide epidemiological study of point prevalence was conducted. Using a multistage cluster stratified random sampling strategy. The sample distribution was described, and the point prevalence of affective disorders was estimated. Chi-squared tests were used to compare disease prevalence based on sex and age. Comorbid ratios for MDD, DD and BP were calculated. RESULTS The total number of cases in Stage 1 was 72,107 (aged 6-16 years). The point prevalence of MDD, DD and BP were 2.004 % (95 % CI: 1.902 to 2.106), 0.352 % (95 % CI: 0.309 to 0.395) and 0.856 % (95 % CI: 0.788 to 0.923), respectively. The total prevalence of affective disorder was 3.212 % (95 % CI: 3.079 to 3.338). The total prevalence of affective disorders between sexes (female: 3.834 % versus male: 2.587 %, χ2 = 90.155, p < 0.001) was consistent with the gender difference in MDD, DD and MD. The total prevalence of affective disorders in adolescents was higher than that in children (adolescents: 5.024 % versus children: 1.863 %, χ2 = 566.841, p < 0.001). CONCLUSIONS Our study is the first nationwide survey on the prevalence of affective disorders among school-attending children and adolescents aged 6-16 in China. Our results also highlighted the importance of addressing comorbidities in future studies of affective disorders.

Abstract
PURPOSE The aim of this study was to compare bipolar disorder (BD) patients with age- and sex-matched healthy individuals in order to assess the choroidal structural alterations, retinal nerve fiber layer (RNFL) thickness, and retinal changes in BD patients using encanhed depth imaging optic coherence tomography (EDI-OCT). METHOD For this research, 39 eyes of BD patients and 36 eyes of age-matched healthy volunteers were used. Five locations were used to assess the choroidal thickness (CT): subfoveal, 500 µm nasal and 1500 µm nasal to the fovea, 500 µm temporal and 1500 µm temporal to the fovea. Image-J was used to determine the total choroidal area (TCA), luminal area (LA), and choroidal vascularity index (CVI). The Spectralis-OCT device was used to evaluate the central macular thickness (CMT), retinal nerve fiber layer (RNFL), and ganglion cell layer (GCL). The data were statistically compared. RESULTS BD patients had significantly decreased subfoveal, nasal, and temporal CTs than controls (for all three, p = 0.0001). The results of CMT and GCL were found to be thinner than controls. (for all p=0.0001) In comparison to the controls, the mean TCA and LA were decreased in the BD group. (p=0.0001, p=0.0001 respectively,). Between the RNFL and CVI values in the BD and control groups, there was no statistically significant difference (p>0.05). CONCLUSION The results of this investigation showed that the retina and choroid of patients with BD had considerable anatomical changes.

Abstract
OBJECTIVE The number of studies conducted on the evaluation of retinal microvascularity in patients with Bipolar Disorder (BD) is very few. Therefore, in the present study it was aimed to provide a significant diagnostic support and to better understand the relationship between BD and vascular changes by making vascular measurements with Optical Coherence Tomography Angiography (OCTA). METHOD The statistical analysis was performed by comparing OCTA measurements of 48 eyes of 48 euthymic patients followed up with a diagnosis of BD and in remission for at least 6 months, and 45 eyes of 45 age-matched healthy volunteers in the control group. Among the OCTA measurements compared were retinal vessel density analysis, foveal avascular zone measurements, retinal nerve fiber layer, radial peripapillary capillary plexus, ganglion cell-inner plexiform layer values. RESULTS In the multivariate regression model, such variables as nasal quadrant of retinal nerve fiber layer, inferior and nasal quadrants of radial peripapillary capillary plexus and superficial vessel density variables were determined to have a significant and independent effect in differentiating patients with BD from the participants in the healthy control group. CONCLUSION In the present study, for the first time, the OCTA method was used to compare both retinal neurodegeneration and vascularization measurements in those in the BD and the healthy groups. That the effects of drugs other than mood stabilizers were not taken into account is among the limitations of our study.

Associations between comorbid anxiety and sleep disturbance in people with bipolar disorder: Findings from actigraphy and subjective sleep measures. J Affect Disord 2022; 309:165-171. [PMID: 35427709 PMCID: PMC9225955 DOI: 10.1016/j.jad.2022.04.065] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 02/03/2022] [Accepted: 04/10/2022] [Indexed: 12/02/2022]
Abstract
BACKGROUND Studies show that comorbid anxiety disorders are common in people with bipolar disorder. However, little is known about whether this anxiety is associated with sleep disturbance. We investigated, in individuals with bipolar disorder, whether comorbid anxiety disorder is associated with sleep disturbance. METHODS Participants were 101 (64% female) currently euthymic individuals with a history of bipolar disorder. Sleep disturbances were assessed using self-report measures of sleep quality (Pittsburgh Sleep Quality Index, PSQI) and six weeks of sleep monitoring using actigraphy. Bipolar disorder and comorbid anxiety diagnoses were assessed using the Mini International Neuropsychiatric Interview. Multiple regression analyses examined associations between comorbid anxiety and sleep disturbance, whilst controlling for confounding covariates known to impact on sleep. RESULTS A comorbid anxiety disorder was associated with increased sleep disturbance as measured using the PSQI global score (B = 3.58, 95% CI 1.85-5.32, P < 0.001) but was not associated with sleep metrics (total sleep time, sleep onset latency, sleep efficiency, and wake after sleep onset) derived using actigraphy. LIMITATIONS Objective measures of sleep were limited to actigraphy, therefore we were not able to examine differences in sleep neurophysiology. CONCLUSIONS Clinicians should be aware that comorbid anxiety may increase the risk of experiencing subjective sleep disturbance in people with bipolar disorder. Research should assess for evidence of comorbid anxiety when examining associations between sleep and bipolar disorder. Future research should explore the mechanisms by which comorbid anxiety may contribute to subjective sleep disturbances in bipolar disorder using neurophysiological measures of sleep (i.e., polysomnography).

Abstract
OBJECTIVES Neuroimaging studies in patients with bipolar disorder have suggested that a neuropathological process may be effective in this disease. Neurodegenerative changes in the retina can be followed by optical coherence tomography, a non-invasive imaging method that allows in vivo visualization of the retinal layers. The aim of this study was to investigate the possible differences in optical coherence tomography parameters during euthymic, manic, and depressive episodes in patients diagnosed with bipolar disorder. METHODS A total of 150 patients with bipolar disorder were included in the study, divided into three groups (50 patients in a euthymic state, 50 patients in a manic state, and 50 patients in a depressive state) and compared with 50 healthy controls. Ganglion cell complex thickness was measured with automated macular segmentation software of spectral-domain optical coherence tomography. RESULTS Ganglion cell complex thicknesses were thicker in all quadrants in patient groups than the control group but the differences were significant in perifoveal superior and perifoveal inferior quadrants (p < 0.001, p < 0.001). There were no differences in ganglion cell complex thickness among the patient groups (p > 0.05). CONCLUSION The evaluation of ganglion cell complex thickness by spectral-domain optical coherence tomography may give a clue for monitoring neurodegenerative changes in patients with bipolar disorder.

Abstract
PURPOSE To quantify visual and retinal changes in patients with bipolar disorder (BD) over 5 years, compared with controls. METHODS Thirty-eight patients with BD and 122 healthy subjects underwent visual acuity (VA) evaluation, contrast sensitivity vision testing (CSV) with the Pelli Robson and CSV 1000E tests, and retinal thicknesses measurement (ganglion cell layer - GCL- and retinal nerve fiber layer -RNFL-) using Spectralis Optical Coherence Tomography (OCT). All subjects were re-evaluated after 5 years. The relationship between progressive structural changes and disease duration was analysed. RESULTS Visual function parameters in BD patients remained unchanged during the follow up period. A progressive decrease affecting macular and peripapillary RNFL thickness (p < 0.050) was observed in patients. Progressive changes in BD were more pronounced when compared with healthy controls (p < 0.050). A significant correlation between GCL thickness changes and disease duration was found (GCL outer temporal, r=-0.680, p = 0.016; GCL central, r=-0.540, p = 0.038). CONCLUSIONS Progressive axonal loss was detected in BD patients. Visual function parameters were not affected after the 5-year follow up. Despite observed changes in the neuroretina of patients with BD, axonal degeneration in these patients seemed to be mild and might be slowed down by other factors such as BD treatments.

Abstract
A nosografia dos transtornos do humor e do afeto relaciona-se diretamente com as formas de apreensão dos quadros clínicos em cada contexto histórico. É indagado se o resgate histórico contribuiria para melhor compreensão e utilização da atual nosologia dos transtornos de humor. Objetiva-se realizar uma revisão histórica e crítica acerca de suas transformações conceituais e nosológicas com enfoque ao campo médico-psiquiátrico. O recorte pretendido se inicia com a proposição da “Insanidade Maníaco-Depressiva” por Emil Kraepelin em 1899, que é confrontada com as propostas pós-kraepelianas, em especial as de Karl Leonhard. Analisa-se a influência dessas na criação dos sistemas diagnósticos operacionalizados, DSM e CID. O “Transtorno Bipolar” foi um constructo introduzido pelo DSM-III e se mantém em uso até os dias atuais. Aborda-se também propostas posteriores, como a do “Espectro Bipolar”.

Abstract
BACKGROUND To examine the antidepressant efficacy and response predictors of R-DLPFC-LF rTMS for antidepressant-nonresponding BD. METHODS We conducted a single-blind randomized sham-controlled trial for 54 (28 sham, 26 active) patients with antidepressant-nonresponding BD (baseline MADRS ≥ 20). Patients received 15 daily sessions of active or sham neuronavigated rTMS (Figure-of-8 coil, five 1 Hz 60 s 110% RMT trains). Outcome measures included depressive response (≥ 50% MADRS reduction, CGI ≤ 2) and remission (MADRS < 7, CGI = 1) rates, treatment emergent hypo/mania (YMRS), depressive and anxiety symptoms (HAM-A). RESULTS 48 patients (25 sham, 23 active) completed treatment, with 3 drop-outs each in active and sham groups. Active rTMS did not produce superior response or remission rates at endpoint or 6 or 12 weeks (ps > 0.05). There was no significant group * time interaction (ps > 0.05) in a multivariate ANOVA with MADRS, HAMA and YMRS as dependent variables. Exploratory analysis found MADRS improvement to be moderated by baseline anxiety (p = 0.02) and melancholia (p = 0.03) at week 3, and depressive onset at weeks 6 (p = 0.03) and 12 (p = 0.04). In subjects with below-mean anxiety (HAMA < 20.7, n = 24), MADRS improvement from active rTMS was superior to sham at week 3 (ITT, t = 2.49, p = 0.04, Cohen's d = 1.05). No seizures were observed. Groups did not differ in treatment-emergent hypomania (p = 0.1). LIMITATIONS Larger sample size might be needed to power subgroup analyses. Moderation analyses were exploratory. Single-blind design. Unblinding before follow-up assessments due to ethical reasons. CONCLUSIONS 1-Hz 110% RMT (5 × 60 s trains) R-DLPFC-LF rTMS was not effective for antidepressant non-responding BD but may be further investigated at increased dosage and/or in BD patients with low anxiety.

Abstract
BACKGROUND Depending on the classification system used, 5-40% of manic subjects present with concomitant depressive symptoms. This post-hoc analysis evaluates the hypothesis that (hypo)manic subjects have a higher burden of depression than non-(hypo)manic subjects. METHODS Data from 806 Bipolar I or II participants of the Stanley Foundation Bipolar Network (SFBN) were analyzed, comprising 17,937 visits. A split data approach was used to separate evaluation and verification in independent samples. For verification of our hypotheses, we compared mean IDS-C scores ratings of non-manic, hypomanic and manic patients. Data were stored on an SQL-server and extracted using standard SQL functions. Linear correlation coefficients and pivotal tables were used to characterize patient groups. RESULTS Mean age of participants was 40 ± 12 years (range 18-81). 460 patients (57.1%) were female and 624 were diagnosed as having bipolar I disorder (77.4%) and 182 with bipolar II (22.6%). Data of 17,937 visits were available for analyses, split into odd and even patient numbers and stratified into three groups by YMRS-scores: not manic < 12, hypomanic < 21, manic < 30. Average IDS-C sum scores in manic or hypomanic states were significantly higher (p < .001) than for non-manic states. (Hypo)manic female patients were likely to show more depressive symptoms than males (p < .001). Similar results were obtained when only the core items of the YMRS or only the number of depressive symptoms were considered. Analyzing the frequency of (hypo)manic mixed states applying a proxy of the DSM-5 mixed features specifier extracted from the IDS-C, we found that almost 50% of the (hypo)manic group visits fulfilled DSM-5 mixed features specifier criteria. CONCLUSION Subjects with a higher manic symptom load are also significantly more likely to experience a higher number of depressive symptoms. Mania and depression are not opposing poles of bipolarity but complement each other.

Assessment Tool of Bipolar Disorder for Primary Health Care: The SAEBD. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18168318. [PMID: 34444069 PMCID: PMC8392302 DOI: 10.3390/ijerph18168318] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 07/28/2021] [Accepted: 08/02/2021] [Indexed: 12/03/2022]
Abstract
Mixed states are highly prevalent in patients with bipolar disorder and require comprehensive scales. Considering this, the current study aims to develop a measure to assess the full spectrum of clinical manifestations of bipolar disorder. A sample of 88 patients was evaluated; the Hamilton Depression Scale (HAM-D), Montgomery-Asberg Depression Scale (MADRS), and the Young Mania Rating Scale (YMRS) were applied, together with the preliminary version of the Scale for the Assessment of Episodes in Bipolar Disorder (SAEBD). After analyzing the appropriateness and statistical properties of the items, discriminant analysis and analysis of diagnostic capacity were performed. The discriminant functions correctly classified 100% of the cases in euthymia, predominant depressive symptoms or mixed symptoms, as well as 92.3% of the cases with predominant manic symptoms. Overall, the functions correctly classified 98.9% of the cases. The area under the curve (0.935) showed high capacity to discriminate between clinical and non-clinical cases (i.e., in euthymia). The SAEBD sensitivity was 0.95, specificity was 0.71, the Positive Predictive Value (PPV) was 0.88, the Negative Predictive Value (NPV) was 0.87, the Positive Likelihood Ratio (+LR) was 3.33, and the Negative Likelihood Ratio (−LR) was 0.07. In conclusion, the SAEBD is a promising scale that shows high reliability and validity, as well as diagnostic utility as a screening tool for use in diverse health care settings.

Abstract
Differential diagnosis between childhood onset attention-deficit/hyperactivity disorder (ADHD) and bipolar disorder (BD) remains a challenge, mainly due to overlapping symptoms and high rates of comorbidity. Despite this, genetic correlation reported for these disorders is low and non-significant. Here we aimed to better characterize the genetic architecture of these disorders utilizing recent large genome-wide association studies (GWAS). We analyzed independent GWAS summary statistics for ADHD (19,099 cases and 34,194 controls) and BD (20,352 cases and 31,358 controls) applying the conditional/conjunctional false discovery rate (condFDR/conjFDR) statistical framework that increases the power to detect novel phenotype-specific and shared loci by leveraging the combined power of two GWAS. We observed cross-trait polygenic enrichment for ADHD conditioned on associations with BD, and vice versa. Leveraging this enrichment, we identified 19 novel ADHD risk loci and 40 novel BD risk loci at condFDR <0.05. Further, we identified five loci jointly associated with ADHD and BD (conjFDR < 0.05). Interestingly, these five loci show concordant directions of effect for ADHD and BD. These results highlight a shared underlying genetic risk for ADHD and BD which may help to explain the high comorbidity rates and difficulties in differentiating between ADHD and BD in the clinic. Improving our understanding of the underlying genetic architecture of these disorders may aid in the development of novel stratification tools to help reduce these diagnostic difficulties.

Abstract
Much evidence shows that some Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5)-defined unipolar depression (UD) with bipolarity manifests bipolar diathesis. Little is known about the cognitive profiles of patients with depression with bipolarity (DWB). The study aimed to investigate the differences in cognitive profiles among patients with bipolar depression (BD), major depressive disorder (namely, UD), and DWB. Drug-naïve patients with BD, UD, and DWB and healthy controls (HC) were recruited (30 cases in each group). Cognitive function was evaluated by THINC-it (THINC-intelligent tool), Wisconsin Card Sorting Test (WCST), and continuous performance test (CPT). For THINC-it, no significant differences of the Z-scores in both objective and subjective factors were found between the DWB group and BD group, but the Z-scores in the BD group were significantly lower than those in the UD group. For WCST, significant differences were found between the BD group and DWB group in the number of responses, categories completed, trails to completed first category, perseverative responses, and perseverative errors. All the indices of WCST in the DWB group were significantly worse than those in the UD group except for trails to completed first category and total number of response correct. For CPT, only scores of leakage responses and false responses in the four-digit number in the BD group and DWB group were significantly higher than those in the UD group; no significant difference was found between the BD group and DWB group. The results indicated that patients with DWB might perform differently from those with UD but similarly to those with BD with cognition impairment.

Abstract
Light exposure at night disrupts circadian-regulated biological functions, including mood. However, the consequence of fragmenting the night period and distributing it across the 24-hr period is less understood. Here we show that fragmenting an 8 -h and 6 -h night into equally distributed 2 -h periods throughout the 24-hr day results in period lengthening of the circadian rhythm in mice. Furthermore, mice exhibited less anxiety, which indicates increased risk-taking behavior, and a lack of pleasure-seeking, known as anhedonia. The successive alley and open field tests were used to assess anxiety, while the sucrose preference test was used to assess anhedonia. Analysis of depressive-like behaviors with the forced swim and tail suspension tests were not observed. After two weeks in 12 h light - 12 h dark, mice exposed to the fragmented night recovered and exhibited normal behaviors for both anxiety and anhedonia. Our results are congruent with published studies that describe the detrimental effects of constant light conditions on circadian rhythms and mood. These findings unveil the negative impact that fragmenting the day-night cycle has on circadian rhythms and mood.

Abstract
Symptoms of subclinical hypomania (SHM) are common in the general population of adolescents and young adults. SHM are most often transient yet might be risk markers of later bipolar disorder. The current study aimed to assess the clinical correlates of SHM at age 11 in the general population, examine the continuity of SHM from age 11-age 16 and explore the clinical precursors of age 16 SHM. As part of the Copenhagen Child Cohort 2000, 1,632 preadolescents participated in the examination of SHM and various clinical correlates at age 11, 893 were re-assessed for SHM at age 16 years. At age 11, SHM, psychotic experiences and depressive symptoms were assessed by semi-structured psychopathological interviews. Furthermore, the participants were diagnostically assessed by the Development and Well-Being Assessment and interviewed about sleep length. At age 16, SHM was assessed by self-report, using the Hypomania Checklist-32. Cannabis use occurring at age 15 or earlier was assessed at age 16. At age 11, SHM was associated with depressive disorders (Relative Risk [RR] = 2.96 [95% CI 1.26–6.96]), interview-based depressive symptoms (RR = 9.22 [5.93–14.34]), neurodevelopmental disorders (RR = 2.94 [1.66–5.20]), psychotic experiences (RR = 4.51 [2.90–7.01]) and insufficient sleep (RR = 2.10 [1.28–3.43]. In the longitudinal analyses, age 16 SHM was preceded by age 11 SHM (RR = 1.89 [1.02–3.49]), psychotic experiences (RR = 2.06, [1.28–3.33]), emotional disorders (RR = 1.77, [1.02–3.09]) and cannabis use (RR = 3.14, [1.93–5.10]), after mutual adjustment and adjustment for sex, and sociodemographic factors. In conclusion, age 11 SHM was statistically significantly associated with other types of psychopathology in cross-sectional analyses and showed some continuity with later self-reported SHM at age 16. Particularly early psychotic experiences and cannabis use stood out as independent precursors of self-reported SHM and might constitute important risk markers for the development of future SHM and bipolar disorder. An important potential caveat of the current study includes the self-report assessment of SHM.

J Affect Disord 2021; 282:426-433. [PMID: 33422818 DOI: 10.1016/j.jad.2020.12.151] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Revised: 11/03/2020] [Accepted: 12/23/2020] [Indexed: 12/18/2022]
Abstract
BACKGROUND To date, the lifetime prevalence of Bipolar Disorder (BD) and BD patients' access to mental health care in England has not been systematically studied. METHODS We used data from the Adult Psychiatric Morbidity Survey 2014 (N = 7546). The Mood Disorders Questionnaire (MDQ) was used to screen for BD. Associations between sociodemographic and clinical variables and use of mental health services were investigated. Weighted regression modelling established factors associated with being in receipt of care for mental health problems over the last year. RESULTS The lifetime prevalence of BD in the community in England was 1.7%. Approximately 40% had not received mental health care in the last year, and only 16.9% had received BD specific treatment. 14.6% had asked for a specific form of help but not received it. Psychopathology differed between individuals who successfully sought care and those who didn't. Obtaining care was independently associated with female sex (p<0.0001, odds ratio(OR):4.65 (Confidence Interval (CI):2.18-10.30), unemployment (p = 0.02, OR: 2.65 (C.I: 1.23-5.88) and suicidal ideation (p = 0.04, OR: 3.36, (C.I: 1.04-10.89). LIMITATIONS The MDQ is less sensitive than some of the longer measures, especially in the general population. Some between-group comparisons may have suffered from limited power. CONCLUSIONS The lifetime prevalence of BD in England was similar to rates worldwide. Most people with BD had not received any specific treatment for the condition in the last year, while 1 in 7 had requested specific help but did not receive it. Secondary mental health services in England for BD appear suboptimal.

Abstract
Mental health disorders are a leading cause of disability worldwide. Challenges such as disease heterogeneity, incomplete characterization of the targets of existing drugs and a limited understanding of functional interactions of complex genetic risk loci and environmental factors have compromised the identification of novel drug candidates. There is a pressing clinical need for drugs with new mechanisms of action which address the lack of efficacy and debilitating side effects of current medications. Here we discuss a novel strategy for neuropsychiatric drug discovery which aims to address these limitations by identifying disease-related functional responses ('functional cellular endophenotypes') in a variety of patient-derived cells, such as induced pluripotent stem cell (iPSC)-derived neurons and organoids or peripheral blood mononuclear cells (PBMCs). Disease-specific alterations in cellular responses can subsequently yield novel drug screening targets and drug candidates. We discuss the potential of this approach in the context of recent advances in patient-derived cellular models, high-content single-cell screening of cellular networks and changes in the diagnostic framework of neuropsychiatric disorders.

Abstract
Objective: Recurrent events data is one of the most important types of survival data whose main feature is correlation between individual’s observations. The aim of this study was to analyze the time to bipolar disorder (BD) relapse and determine the related factors using recurrent events models. Method: In this retrospective study, records of 104 BD patients with at least one relapse who were admitted for the first time (2001-2015) in Farabi hospital of Kermanshah were gathered to identify the factors influencing the time intervals between the recurrent survivals data using the Cox model with and without frailty (shared frailty), once with frailty gamma distribution and once with log-normal distribution frailty. All calculations were performed using R and SPSS software, versions 3.0.2 and 16 and the level of significance was considered at 0.05. Results: Among the employed models, Cox model with lognormal shared frailty showed better fit for BD recurrent survival data. According to results of Cox model with lognormal frailty, 2 factors (marital status and history of veteran) were identified to affect the time intervals between relapses. Conclusion: Because of the better fit of the models with the frailty effect on data, the correlation between the recurrent time intervals of each subject's relapse of BD was confirmed. Also, since the risk of subsequent relapses was less in married and veteran patients, marriage and emotional care supports can be considered as effective factors in reducing the risk of subsequent relapses of this disease.

Abstract
MATERIALS AND METHODS Twenty-five eyes of 25 patients with bipolar disorder and 74 eyes of 74 healthy controls underwent retinal measurements of retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) thickness. Measurements were obtained using the Spectralis-OCT device with the new Posterior Pole protocol which assesses the macular area by analyzing retinal thickness in a grid of 64 (8*8) cells. RESULTS Significant differences (p < 0.05) in RNFL and GCL thickness were found between BD patients and healthy controls, in parafoveal and perifoveal cells respectively. Significant inverse correlations were found between RNFL and GCL thinning at their thickest location and the duration of bipolar disorder. Several predictive variables were observed with a binary logistic regression for the presence/absence of BD: cell 1.3 RNFL (p = 0.028) and GCL in cells 7.8 (p = 0.012), 2.7 (p = 0.043) and 1.3 (p = 0.047). CONCLUSION Posterior Pole OCT protocol is a useful tool to assess changes in the inner retinal layers in bipolar disorder. These observed changes, especially those affecting the GCL, may be associated with disease evolution and may be predictive of the presence of the disease. OCT data could potentially be a useful tool for clinicians to diagnose and monitor BD patients.

Exploring cellular markers of metabolic syndrome in peripheral blood mononuclear cells across the neuropsychiatric spectrum. Brain Behav Immun 2021; 91:673-682. [PMID: 32898636 DOI: 10.1016/j.bbi.2020.07.043] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2020] [Revised: 07/28/2020] [Accepted: 07/29/2020] [Indexed: 12/18/2022] Open
Abstract
Recent evidence suggests that comorbidities between neuropsychiatric conditions and metabolic syndrome may precede and even exacerbate long-term side-effects of psychiatric medication, such as a higher risk of type 2 diabetes and cardiovascular disease, which result in increased mortality. In the present study we compare the expression of key metabolic proteins, including the insulin receptor (CD220), glucose transporter 1 (GLUT1) and fatty acid translocase (CD36), on peripheral blood mononuclear cell subtypes from patients across the neuropsychiatric spectrum, including schizophrenia, bipolar disorder, major depression and autism spectrum conditions (n = 25/condition), relative to typical controls (n = 100). This revealed alterations in the expression of these proteins that were specific to schizophrenia. Further characterization of metabolic alterations in an extended cohort of first-onset antipsychotic drug-naïve schizophrenia patients (n = 58) and controls (n = 63) revealed that the relationship between insulin receptor expression in monocytes and physiological insulin sensitivity was disrupted in schizophrenia and that altered expression of the insulin receptor was associated with whole genome polygenic risk scores for schizophrenia. Finally, longitudinal follow-up of the schizophrenia patients over the course of antipsychotic drug treatment revealed that peripheral metabolic markers predicted changes in psychopathology and the principal side effect of weight gain at clinically relevant time points. These findings suggest that peripheral blood cells can provide an accessible surrogate model for metabolic alterations in schizophrenia and have the potential to stratify subgroups of patients with different clinical outcomes or a greater risk of developing metabolic complications following antipsychotic therapy.

Global estimates of service coverage for severe mental disorders: findings from the WHO Mental Health Atlas 2017. Glob Ment Health (Camb) 2021; 8:e27. [PMID: 34367650 PMCID: PMC8320004 DOI: 10.1017/gmh.2021.19] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Revised: 04/14/2021] [Accepted: 05/10/2021] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND The study estimated service coverage for severe mental disorders (psychosis, bipolar disorder and moderate-severe depression), globally and regionally, using data collected from the Mental Health Atlas 2017. METHODS Service coverage was defined as the proportion of people with a disorder contacting a mental health service among those estimated to have the disorder during a 12-month period. We drew upon 12-month service utilisation data from the Mental Health Atlas 2017. Expected prevalent cases of individual disorders were estimated using the disorder-specific prevalence rate estimates of the Global Burden of Disease Study 2016 and total population sizes. Methods for assessing the validity of country-reported service utilisation data were developed and applied. OUTCOMES From 177 countries, 50 countries provided reliable service coverage estimates for psychosis, along with 56 countries for bipolar disorder, and 65 countries for depression. The mean service coverage for psychosis was lowest in low- [10.9% (95% confidence interval (CI) 3.3-30.4)] and lower middle-income countries [21.5% (95% CI 11.9-35.7)] and highest in high-income countries [59.5% (95% CI 42.9-74.1)]. Service coverage for bipolar disorder ranged between 3.1% (95% CI 0.8-11.5) and 10.4% (95% CI 6.7-15.8). Mean service coverage for moderate-severe depression ranged between 2.9% (95% CI 1.3-6.3) for low-income countries and 31.1% (95% CI 18.3-47.6) for high-income countries. INTERPRETATION The reporting method utilised by the Mental Health Atlas appears to be reliable for psychosis but not for depression. This method of estimating service coverage provides progress in tracking an important indicator for mental health; however, it highlights that considerable work is needed to further develop global mental health information systems.

Abstract
BACKGROUND Knowledge on the comparative effectiveness of pharmacological treatments to prevent suicide mortality in bipolar disorder is still lacking. METHODS We studied the risk of suicide mortality during 1996-2012 among all patients who had been hospitalized due to bipolar disorder in Finland (n = 18,018; mean follow-up time 7.2 years) using nation-wide databases. We used a Cox proportional hazards model. Analyses were adjusted for the effects of time since diagnosis, order of treatments, current use of other treatments, polypharmacy, number of suicidal hospitalizations within 2 year (indicator of inherent risk of relapse), age at index date, sex, and calendar year of index date. In secondary analysis, the first 30 days were omitted from analysis after initiation of a psychopharmacological treatment to control for protopathic bias. RESULTS In comparison between use and no use among specific agents, only lithium (HR 0.33, 95%CI 0.24-0.47, p<0.0001) and valproic acid (HR 0.61, 95%CI 0.48-0.79, p=0.0002) were associated with a significantly decreased risk of suicide in bipolar disorder. Lithium showed a 42% lower risk for suicide mortality compared to valproic acid (HR 0.58, 95% CI 0.39-0.86, p = 0.007). Hypnotics were associated with a significantly (HR 1.52, 95%CI 1.22-1.90, p=0.0002) higher risk of suicide. LIMITATIONS Only hospitalized patients were included. CONCLUSIONS Lithium should be considered as treatment of choice for patients with bipolar disorder who are at high risk for suicide. Hypnotic use among suicidal patients indicates need for close monitoring of these patients.

Abstract
BACKGROUND In clinical practice it is often challenging to determine whether mood disturbances should be considered a state or trait characteristics. This study is important to understand the influence of temperaments in the diagnosis of depression. The objective of the present study was to compare the frequency of three types of affective temperament (dysthymia, hyperthymia and cyclothymia) among older adults with major depression compared to non-psychiatric control patients. METHODS A case-control study comparing 50 patients with major depression aged 65 years or above with a comparison group of 100 non-psychiatric controls. Affective temperaments were assessed using the TEMPS-A questionnaire. The 17-item Hamilton Depression Rating Scale and the Young mania Rating Scale were used for the assessment of symptoms of depression and mania, respectively. RESULTS In the sample 80% had an affective temperament, most commonly hyperthymia (67.3%). In depressive patients 48% had criteria for hyperthymic temperament against 77% of the controls (OR= 0.3, 95%CI 0.1-0.7). 38.8% of these patients presented cyclothymic temperament, whereas among controls, 12% fulfilled criteria (OR= 2.9, 95%CI 1.1-7.2). LIMITATIONS The sample was relatively small, and their educational level was very low. CONCLUSION A cyclothymic temperament may predict major depression unlike hyperthymia. Whether the effectiveness of mood stabilizers in unipolar disorder is moderated by a cyclothymic temperament and should be explored in future randomized controlled trials.

Abstract
PURPOSE To evaluate visual and retinal changes in patients with bipolar disorder. To analyze the correlation between structural changes and visual function parameters. METHODS Thirty patients with bipolar disorder and 80 healthy controls underwent visual function evaluation with Early Treatment Diabetic Retinopathy Study charts at 100%, 2.50%, and 1.25% contrast, Pelli-Robson chart, and color vision Farnsworth and Lanthony tests. Analysis of the different retinal layers was performed using Spectralis optical coherence tomography with automated segmentation software. Correlation analysis between structural and functional parameters was conducted. RESULTS Patients with bipolar disorder presented worse color vision compared with controls (Lanthony's index, P = 0.002). Full macular thickness, the retinal nerve fiber layer (RNFL), ganglion cell layer, and inner plexiform layer were reduced in patients compared with healthy individuals (P < 0.005). The inner nuclear layer was significantly thickened in patients (P < 0.005). Peripapillary RNFL thickness was reduced in all temporal sectors (P < 0.005). Significant correlations were found between visual acuity and the RNFL thickness, the Pelli-Robson score and the inner plexiform layer, and between the Lanthony's color index and the ganglion cell layer thickness. CONCLUSION Patients with bipolar disorder present quantifiable thinning of the macular RNFL, ganglion cell layer, and inner plexiform layer, as well as in the peripapillary RNFL thickness, and increasing thinning in the inner nuclear layer.

Abstract
Objective It is known that the risk of anxiety disorders and depression in infertile women increases and their quality of life deteriorates. Temperamental characteristics are considered as predictors of mood disorders. The aim of this study was to investigate temperamental characteristics in infertile women and their effects on depression and anxiety levels, and the quality of life, and to reveal the differences and level of relationship compared to healthy women. Method Fourty-four female patients with primary infertility and 30 healthy female controls were included in this study. Temperamental characteristics of the participants were assessed with Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire version (TEMPS-A). Depression and anxiety severity were evaluated with Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). To evaluate the quality of life, Short Form 36 (SF-36) health survey questionnaire was also applied. Results Hyperthymic temperament scores were higher in infertile women than the control group (p=0.001). BDI scores were positively correlated with depressive and cyclothymic temperament scores, and BAI scores were positively correlated with depressive and anxious temperament scores. A negative correlation was found between hyperthymic temperament and BAI and BDI scores. Hyperthymic temperament scores were positively correlated with both physical and mental subdimension scores of the quality of life scale. Conclusion In this study, hyperthymic temperament in infertile women was shown to be protective against anxiety and depression and it also improves the quality of life. Additional studies are needed to clarify the relationship between hyperthymic temperament and ovarian hormones or other biological parameters.

Abstract
BACKGROUND Depression and anxiety levels, sexual dysfunctions, and affective temperament characteristics of women with lifelong vaginismus (LLV) and their male partners may have important effects on the development, maintenance, and exacerbation of LLV. AIM We aimed to investigate depression and anxiety levels, sexual dysfunctions, and affective temperament characteristics of both women with LLV and their male partners. METHODS 56 women with LLV, their 56 male partners, and 44 couples with no complaints of any sexual function as a control group were included in this study. Dyadic data were analyzed using the Actor-Partner Interdependence Model. OUTCOMES The Beck Depression Inventory, Beck Anxiety Inventory, Golombok Rust Inventory of Sexual Satisfaction, and Temperament Evaluation of Memphis, Pisa, Paris and San Diego Auto Questionnaire Scale were completed by all participants. RESULTS Women with LLV had higher levels of anxiety and depression and had more sexual dysfunctions except for avoidance than those of female controls. Temperament Evaluation of Memphis, Pisa, Paris and San Diego Auto Questionnaire Scale scores were significantly higher in women with LLV for depressive (odds ratio [OR] = 1.27, 95% CI = 1.09-1.49), cyclothymic (OR = 1.31, 95% CI = 1.15-1.49), anxious (OR = 1.22, 95% CI = 1.09-1.38), and irritable (OR = 1.22, 95% CI = 1.04-1.42) temperament than in female controls. It was found that anxiety levels of male partners of women with LLV were higher than those of male controls and that they experienced less sexual satisfaction. Depressive (OR = 1.31, 95% CI = 1.07-1.61) and cyclothymic (OR = 1.18, 95% CI = 1.04-1.34) temperament scores were significantly higher in male partners of women with LLV than in male controls. The Actor-Partner Interdependence Model analyses show that hyperthymic temperament in male partners of women with LLV and anxious and depressive temperament in women with LLV have a negative effect on their own sexual functions. In terms of partner effect, it was found that men with hyperthymic temperament had a negative effect on the sexual functions of women with LLV and men with depressive temperament had a positive effect. CLINICAL IMPLICATIONS The individual characteristics of both the women and their male partners have an impact on LLV. STRENGTHS & LIMITATIONS The sample size was relatively small to assess affective temperaments. The inclusion of male partners in the study contributed to our understanding of couples with LLV. CONCLUSION Our results indicate that affective temperaments detected in women with LLV (depressive, cyclothymic, anxious and irritable) and their male partners (depressive and cyclothymic) have an effect on the development, maintenance, and exacerbation of LLV, and affective temperaments have an effect on both their own and partner's sexual functions.

Abstract
AbstractBackgroundTo date, nearly all research of subtype differences in ADHD has been performed in children and only two studies, with conflicting results, have covered this subject in adults with ADHD.ObjectiveThis study examined subtype differences in the clinical presentation of ADHD-symptoms, related psychopathological features, psychosocial functioning and comorbid psychiatric disorders in adults with ADHD.MethodOne hundred and eighteen adults with ADHD, diagnosed according to DSM-IV criteria, and a population based control group underwent diagnostic evaluations with clinical interviews for ADHD, DSM-IV disorders and demographic features. Comparisons were made between ADHD combined type (n = 64), predominantly inattentive type (n = 30) and predominantly inattentive type, anamnestically combined type (n = 24), relative to each other and to a community control group (n = 70).ResultsThe four groups did not differ in age and gender composition. All ADHD groups had significantly less education, were significantly more often unemployed and reported significantly more lifetime psychiatric comorbidity than controls. In comparison to each other, the three ADHD groups differed mainly in core symptoms and the pattern of comorbid psychiatric disorders, whereas no prominent differences in associated psychopathological features and most of the assessed psychosocial functions could be found. Patients with ADHD combined type and inattentive, anamnestically combined type both presented with significantly more hyperactive symptoms and also showed more impulsive symptoms than those with the predominantly inattentive type. With a similar overall lifetime psychiatric comorbidity in the three groups, patients with ADHD combined type and inattentive, anamnestically combined type suffered significantly more from lifetime substance use disorders than patients with predominantly inattentive type.ConclusionOur results clearly show impaired psychosocial adjustment and elevated risk for additional psychiatric disorders in adults with all subtypes of ADHD, compared to healthy controls. They provide preliminary evidence that in adult ADHD there might be a subgroup of patients, which is classified as predominantly inattentive subtype according to current diagnostic criteria, but which in its clinical presentation is in between ADHD combined and inattentive type. Further studies are needed to evaluate this finding and to gain a clear picture of its validity.

Abstract
AbstractThis prospective, longitudinal study compared the frequency and pattern of mood changes between outpatients receiving usual care for bipolar disorder who were either taking or not taking antidepressants. One hundred and eighty-two patients with bipolar disorder self-reported mood and psychiatric medications for 4 months using a computerized system (ChronoRecord) and returned 22,626 days of data. One hundred and four patients took antidepressants, 78 did not. Of the antidepressants taken, 95% were selective serotonin or norepinephrine reuptake inhibitors, or second-generation antidepressants. Of the patients taking an antidepressant, 91.3% were concurrently taking a mood stabilizer. The use of antidepressants did not influence the daily rate of switching from depression to mania or the rate of rapid cycling, independent of diagnosis of bipolar I or II. The primary difference in mood pattern was the time spent normal or depressed. Patients taking antidepressants frequently remained in a subsyndromal depression. In this naturalistic study using self-reported data, patients with bipolar disorder who were taking antidepressants—overwhelmingly not tricyclics and with a concurrent mood stabilizer—did not experience an increase in the rate of switches to mania or rapid cycling compared to those not taking antidepressants. Antidepressants had little impact on the mood patterns of bipolar patients taking mood stabilizers.

Abstract
AbstractBipolar disorders are frequently not diagnosed until long after their onset, leaving patients with no or correspondingly inadequate treatment. The course of the disorder is all the more severe and the negative repercussions for those affected all the greater. Concerted research effort is therefore going into learning how to recognize bipolar disorders at an early stage. Drawing on current research results, this paper presents considerations for an integrative Early Symptom Scale with which persons at risk can be identified and timely intervention initiated. This will require prospective studies to determine the predictive power of the risk factors integrated into the scale.

Abstract
PURPOSE OF REVIEW The nosology and management of antidepressant-associated hypomania (AAH) in the treatment of unipolar depression requires clarification. We sought to review recent studies examining AAH, focusing on risk factors, differing explanatory models, and management strategies. RECENT FINDINGS AAH occurs more frequently in those of female gender, younger age, and with a bipolar disorder (BP) family history. Depressive features (e.g., suicidal ideation, psychotic symptoms) in those with AAH were similar to those with established BPs. Explanatory models for AAH describe it as (i) a transient iatrogenic event, (ii) a specific "bipolar III" disorder, (iii) indicative of "conversion" to BP, (iv) acceleration of BP, and (v) coincidental and unrelated to antidepressant medication. Management recommendations include antidepressant cessation, atypical antipsychotic medications, or switching to a mood stabilizer. Determinants and management of AAH in the treatment of unipolar depression requires considerable clarification, likely to be achieved by close clinical review and refined research studies.

Abstract
Diagnosis and monitoring of psychiatric disorders rely heavily on subjective self-reports of clinical symptoms, which are complicated by the varying consistency of accounts reported by patients with an impaired mental state. Hence, more objective and quantifiable measures have been sought to provide clinicians with more robust methods to evaluate symptomology and track progression of disease in response to treatments. Owing to the shared origins of the retina and the brain, it has been suggested that changes in the retina may correlate with structural and functional changes in the brain. Vast improvements in retinal imaging, namely optical coherence tomography (OCT) and electrodiagnostic technology, have made it possible to investigate the eye at a microscopic level, allowing for the investigation of potential biomarkers in vivo. This review provides a summary of retinal biomarkers associated with schizophrenia, bipolar disorder and major depression, demonstrating how retinal biomarkers may be used to complement existing methods and provide structural markers of pathophysiological mechanisms that underpin brain dysfunction in psychiatric disorders.

Abstract
BACKGROUND Atypical antipsychotics are used for the treatment of acute mania, either as monotherapy or in combination with lithium or divalproex, which have a better tolerability profile as compared with typical antipsychotics. Asenapine, a newer atypical antipsychotic, has been found to be effective for the treatment of mania, with efficacy similar to olanzapine. The objective of the study was to compare the efficacy and safety of asenapine and olanzapine when used in combination with divalproex in patients with acute mania. METHODS One hundred twenty patients aged 18 to 55 years, diagnosed with manic episode, were randomized to receive either flexible dose of sublingual asenapine (10-20 mg/d) or tablet olanzapine (10-20 mg/d), in combination with valproate 20 mg/kg per day for a period of 6 weeks. Efficacy was measured as change in Young Mania Rating Scale and Clinical Global Impression-Bipolar using intention-to-treat analysis with last observation carried forward, and safety was measured using Udvalg for Kliniske Undersøgelser scale and Modified Simpson-Angus Extrapyramidal Side Effects Scale. RESULTS There was a significant reduction in Young Mania Rating Scale and Clinical Global Impression-Bipolar scores over time in both groups, with a significantly higher reduction in the olanzapine group as shown by the group × time interaction effect. Higher weight gain, increased sleep and appetite, and tremors were seen in the olanzapine-treated patients as compared with asenapine-treated patients; however, tongue hypesthesia was seen in the asenapine group only. CONCLUSIONS This study found that asenapine was an effective and well-tolerated atypical antipsychotic alternative to olanzapine in combination with divalproex for the short-term management of acute mania.

Abstract
Since ancient times it is known that melancholia and sleep disturbances co-occur. The introduction of polysomnography into psychiatric research confirmed a disturbance of sleep continuity in patients with depression, revealing not only a decrease in Slow Wave Sleep, but also a disinhibition of REM (rapid eye movement) sleep, demonstrated as a shortening of REM latency, an increase of REM density, as well as total REM sleep time. Initial hopes that these abnormalities of REM sleep may serve as differential-diagnostic markers for subtypes of depression were not fulfilled. Almost all antidepressant agents suppress REM sleep and a time-and-dose-response relationship between total REM sleep suppression and therapeutic response to treatment seemed apparent. The so-called Cholinergic REM Induction Test revealed that REM sleep abnormalities can be mimicked by administration of cholinomimetic agents. Another important research avenue is the study of chrono-medical timing of sleep deprivation and light exposure for their positive effects on mood in depression. Present day research takes the view on insomnia, i.e., prolonged sleep latency, problems to maintain sleep, and early morning awakening, as a transdiagnostic symptom for many mental disorders, being most closely related to depression. Studying insomnia from different angles as a transdiagnostic phenotype has opened many new perspectives for research into mechanisms but also for clinical practice. Thus, the question is: can the early and adequate treatment of insomnia prevent depression? This article will link current understanding about sleep regulatory mechanisms with knowledge about changes in physiology due to depression. The review aims to draw the attention to current and future strategies in research and clinical practice to the benefits of sleep and depression therapeutics.

Bivariate genome-wide association analyses of the broad depression phenotype combined with major depressive disorder, bipolar disorder or schizophrenia reveal eight novel genetic loci for depression. Mol Psychiatry 2020; 25:1420-1429. [PMID: 30626913 PMCID: PMC7303007 DOI: 10.1038/s41380-018-0336-6] [Citation(s) in RCA: 53] [Impact Index Per Article: 13.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2017] [Revised: 11/15/2018] [Accepted: 12/03/2018] [Indexed: 11/09/2022]
Abstract
Although a genetic basis of depression has been well established in twin studies, identification of genome-wide significant loci has been difficult. We hypothesized that bivariate analyses of findings from a meta-analysis of genome-wide association studies (meta-GWASs) of the broad depression phenotype with those from meta-GWASs of self-reported and recurrent major depressive disorder (MDD), bipolar disorder and schizophrenia would enhance statistical power to identify novel genetic loci for depression. LD score regression analyses were first used to estimate the genetic correlations of broad depression with self-reported MDD, recurrent MDD, bipolar disorder and schizophrenia. Then, we performed four bivariate GWAS analyses. The genetic correlations (rg ± SE) of broad depression with self-reported MDD, recurrent MDD, bipolar disorder and schizophrenia were 0.79 ± 0.07, 0.24 ± 0.08, 0.53 ± 0.09 and 0.57 ± 0.05, respectively. From a total of 20 independent genome-wide significant loci, 13 loci replicated of which 8 were novel for depression. These were MUC21 for the broad depression phenotype with self-reported MDD and ZNF804A, MIR3143, PSORS1C2, STK19, SPATA31D1, RTN1 and TCF4 for the broad depression phenotype with schizophrenia. Post-GWAS functional analyses of these loci revealed their potential biological involvement in psychiatric disorders. Our results emphasize the genetic similarities among different psychiatric disorders and indicate that cross-disorder analyses may be the best way forward to accelerate gene finding for depression, or psychiatric disorders in general.

Abstract
Objectives. Certain studies have claimed that borderline personality disorder (BPD) could be evaluated as a subtype of bipolar disorder (BD), whereas others have argued that BPD should be regarded as an independent disorder because of its distinct clinical features. The aim of this study was to investigate if there was a difference between these 2 disorders biologically based on EEG recordings. Methods. A total of 111 subjects (11 healthy, 25 BPD, 75 BD) who had resting EEG recordings were included. The EEGs were analyzed to compute absolute power values. Results. One-way analysis of variance results revealed statistically significant differences among the 3 groups on 55 out of 229 EEG variables. However, post hoc analysis indicated that all of the significant changes were between healthy and patient groups and no significant differences were found between 2 clinical groups. Conclusion. The findings suggested that these 2 clinical entities are biologically similar; however, further research should be performed to explain the basis clinical differences between the 2 disorders.

Abstract
There is growing recognition that the gut microbiome is an important regulator for neurological functions. This review provides a summary on the role of gut microbiota in various neurological disorders including neurotoxicity induced by environmental stressors such as drugs, environmental contaminants, and dietary factors. We propose that the gut microbiome remotely senses and regulates CNS signaling through the following mechanisms: 1) intestinal bacteria-mediated biotransformation of neurotoxicants that alters the neuro-reactivity of the parent compounds; 2) altered production of neuro-reactive microbial metabolites following exposure to certain environmental stressors; 3) bi-directional communication within the gut-brain axis to alter the intestinal barrier integrity; and 4) regulation of mucosal immune function. Distinct microbial metabolites may enter systemic circulation and epigenetically reprogram the expression of host genes in the CNS, regulating neuroinflammation, cell survival, or cell death. We will also review the current tools for the study of the gut-brain axis and provide some suggestions to move this field forward in the future.

Abstract
AIM To study clinical features of depressive episode with the onset in late adolescence associated with the risk of bipolar affective disorder (BAD). MATERIAL AND METHODS Forty patients with BAD (ICD-10 F31), who experienced depressive state at the age of 15-18 years corresponding to the diagnostic criteria of 'Depressive episode' (F32), were examined. The duration of follow-up was from 3 to 5 years. Clinical-psychopathologic, follow-up, statistical methods were applied. RESULTS Duration of depressive episodes did not exceed 6 months in 70% of patients with BAD. Characteristic clinical features included the frequent presence of psychomotor retardation, anergia, anhedonia, melancholy, irritability, affective instability with increased emotional reactivity, hypersomnia. Other 'atypical' depressive symptoms were less characteristic. There was a significant incidence of suicidal tendencies, comorbid psychopathic-like behavioral disorders and substance abuse. In most cases, the depressive state was accompanied by a deterioration in social functioning and led to educational maladaptation. CONCLUSION Characteristic clinical features of bipolar depression manifested in late adolescence were a relatively short duration, the prevalence of typical depressive symptoms (melancholy, psychomotor retardation), irritability, increased emotional reactivity, hypersomnia, a significant incidence of suicidal tendencies.

Abstract
BACKGROUND Subthreshold hypomania is defined as a distinct period of elevated, expansive or irritable mood lasting for at least four days, but insufficient to fulfill the criteria of hypomania. This study aimed to investigate the association between suicidality and subthreshold hypomania in subjects with and without major depressive disorder (MDD). METHODS Face-to-face interviews were completed for 12,526 adults, randomly selected through a one-person-per-household method, using the Korean version of the Composite International Diagnostic Interview (K-CIDI) and a questionnaire relative to lifetime suicide attempts (LSA). RESULTS Of the 12,526 participants, 11,701 did not have MDD, and 825 were diagnosed with MDD. The MDD with subthreshold hypomania group (n = 72) revealed significantly higher rates of LSA and post-traumatic stress disorder (PTSD) than those without (n = 753). Compared to the no MDD without subthreshold hypomania group (n = 11,571), the no MDD with subthreshold hypomania group (n = 130) showed a significantly higher prevalence of suicidality and comorbid conditions. In multivariate logistic regression analyses of depressive symptoms, subthreshold hypomania was significantly associated with morning worsening of mood. The MDD with subthreshold hypomania group was significantly associated with LSA (AOR=16.82, 95% CI 9.81-28.83, p< 0.001), compared to the no MDD group without subthreshold hypomania. Compared to the MDD without subthreshold hypomania group, the MDD with subthreshold hypomania group revealed a significant association with LSA (AOR=2.08, 95% CI 1.20-3.62, p< 0.001). CONCLUSIONS A history of subthreshold hypomania doubled the risk of LSA in patients with MDD compared to those without subthreshold hypomania.

Abstract
OBJECTIVE This study primarily focused on the relationship between comorbid attention deficit-hyperactivity disorder (ADHD), mixed features and bipolarity in major depressive patients. METHODS The sample comprised 2777 patients with Major Depressive Episode (MDE) enrolled in a multicentre, multinational study originally designed to assess different definitions of mixed depression. Socio-demographic, familial and clinical characteristics were compared in patients with (ADHD + ) and without (ADHD-) comorbid ADHD. RESULTS Sixty-one patients (2.2%) met criteria for ADHD. ADHD was associated with a higher number of (hypo)manic symptoms during depression. Mixed depression was more represented in ADHD + patients than in ADHD- using both DSM-5 and experimental criteria. Differences were maintained after removing overlapping symptoms between (hypo)mania and ADHD. ADHD in MDE was also associated with a variety of clinical and course features such as onset before the age of 20, first-degree family history of (hypo)mania, past history of antidepressant-induced (hypo)manic switches, higher number of depressive and affective episodes, atypical depressive features, higher rates of bipolarity specifier, psychiatric comorbidities with eating, anxiety and borderline personality disorders. LIMITATIONS The study was primarily designed to address mixed features in ADHD, with slightly reduced sensitivity to the diagnosis of ADHD. Other possible diagnostic biases due to heterogeneity of participating clinicians. CONCLUSIONS In a sample of major depressive patients, the comorbid diagnosis of current ADHD is associated with bipolar diathesis, mixed features, multiple psychiatric comorbidity and a more unstable course. Further prospective studies are necessary to confirm the possible mediating role of temperamental mood instability and emotional dysregulation in such a complex clinical presentation.

Abstract
INTRODUCTION Subthreshold presentations of bipolarity (BSPs) pose a diagnostic conundrum, in terms of whether they should be conceptualized and treated similarly as traditionally defined bipolar disorders (BD). While it has been argued that BSPs are on a pathophysiologic continuum with traditionally defined BDs, there has been limited examination of biological and objective markers in these presentations to validate this assertion. Areas covered: The authors review studies examining genetic, neurobiological, cognitive and peripheral markers in BSPs, encompassing clinical and non-clinical populations with subthreshold hypo/manic symptoms. Results are placed in the context of previously identified markers in traditionally defined BDs. Expert commentary: There have been few studies of objective and biological markers in subthreshold presentations of BD, and results are mixed. While abnormalities in brain structure/functioning, peripheral inflammatory, and cognitive markers have been reported, it is unclear whether these findings are specific to BD or indicative of broad affective pathology. However, some studies suggest that increased sensitivity to reward and positive stimuli are shared between subthreshold and traditionally defined BDs, and may represent a point of departure from unipolar major depression. Further examination of such markers may improve understanding of subthreshold bipolar presentations, and provide guidance in terms of therapeutic strategies.

Increased Burden of Psychiatric Disorders in Inflammatory Bowel Disease. Inflamm Bowel Dis 2019; 25:360-368. [PMID: 29986021 PMCID: PMC6391845 DOI: 10.1093/ibd/izy235] [Citation(s) in RCA: 148] [Impact Index Per Article: 29.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2018] [Indexed: 12/11/2022]
Abstract
BACKGROUND Psychiatric comorbidity in inflammatory bowel disease (IBD) is well known; however, data from a truly representative sample are sparse. We aimed to estimate the incidence and prevalence of psychiatric disorders in an IBD cohort compared with a matched cohort without IBD. METHODS Using population-based administrative health data from Manitoba, Canada, we identified all persons with incident IBD from 1989 to 2012 and a general population matched cohort (5:1). We applied validated algorithms for IBD, depression, anxiety disorders, bipolar disorder, and schizophrenia to determine the annual incidence of these conditions post-IBD diagnosis and their lifetime and current prevalence. RESULTS There were 6119 incident cases of IBD and 30,573 matched individuals. After adjustment for age, sex, socioeconomic status, region of residence, and year, there was a higher incidence in the IBD cohort compared with controls for depression (incidence rate ratio [IRR], 1.58; 95% confidence interval [CI], 1.41-1.76), anxiety disorder (IRR, 1.39; 95% CI, 1.26-1.53), bipolar disorder (IRR, 1.82; 95% CI, 1.44-2.30), and schizophrenia (IRR, 1.64; 95% CI, 0.95-2.84). Incidence rate ratios were similar for Crohn's disease and ulcerative colitis between males and females and were stable over time. However, within the IBD cohort, the incidence rates of depression, anxiety, and bipolar disorders were higher among females, those aged 18-24 years vs those older than 44 years, urbanites, and those of lower socioeconomic status. The lifetime and current prevalence rates of psychiatric disorders were also higher in the IBD than the matched cohort. CONCLUSIONS The incidence and prevalence of psychiatric disorders are elevated in the IBD population.

Bipolar features in major depressive disorder: Results from the Iranian mental health survey (IranMHS). J Affect Disord 2018; 241:319-324. [PMID: 30142591 DOI: 10.1016/j.jad.2018.08.014] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2018] [Revised: 07/11/2018] [Accepted: 08/07/2018] [Indexed: 01/26/2023]
Abstract
BACKGROUND Past research suggests that individuals suffering from depressive disorders with bipolar features might have different clinical outcomes resembling bipolar disorders. The objectives of this study are to determine the prevalence of bipolar features among individuals meeting the criteria for 12-month major depressive disorder (MDD) in the Iranian population and to examine the demographic and clinical characteristics associated with these features. METHODS Data were drawn from the Iranian Mental Health Survey (IranMHS), a representative household survey of the Iranian population aged 15-64 years. The study sample consisted of all individuals with a 12-month MDD (n = 1014) ascertained by the Composite International Diagnostic Interview (CIDI 2.1) without a lifetime history of bipolar I or II disorders. Mood Disorder Questionnaire (MDQ) was used to screen for the lifetime history of bipolar features among participants with MDD. RESULTS Among participants meeting the 12-month MDD criteria, 22.1% (95% CI: 19.6-24.7) had a lifetime history of bipolar features. Compared with those without these features, participants with bipolar features had higher odds of endorsing suicidal ideations and suicide attempts, comorbid anxiety and substance use disorders, severe impairment, history of psychotic symptoms, some features of atypical depression and fewer depressive symptoms. Associations with comorbid anxiety disorders [Odds Ratio (OR) = 1.43; 95% confidence interval (CI): 1.00-2.03] and history of psychotic symptoms (OR = 2.63 95% CI: 1.81-3.81) persisted in multivariable models. LIMITATION Relying on self-reports of lifetime bipolar symptoms which is open to recall bias, and cross-sectional study design which limits interpretation of outcome and course of MDD are two major limitations of this study. CONCLUSION The presence of bipolar features is associated with a distinct demographic and clinical profile in MDD. Identifying these cases would enhance the homogeneity of the depressive disorder phenotype in general population surveys. Identifying MDD patients with these features has potential clinical implications.

Abstract
The purpose of the present meta-analysis was to compare leukocyte telomere length (LTL), a proposed marker for cell aging, between patients with bipolar disorder (BD) and healthy controls and explore potential moderators for the LTL difference. We searched for the major research databases up to May 2018 for studies that examined LTL in patients with BD and healthy controls. The effect sizes (ESs) of LTL differences from the included studies were pooled using a random-effects model. Furthermore, we adopted subgroup analysis to investigate whether mood status of BD patients or methods for measuring telomere length may influence such differences. We included 10 studies, with a total of 579 patients and 551 controls, in the current meta-analysis and observed significantly shorter LTL in BD patients compared to control subjects. Such differences were found in studies with patients in all mood statuses and in studies using different methods for measuring telomere length. Late-stage BD patients demonstrated more significant LTL shortening than early-stage BD patients. Our current results support the hypothesis of accelerated aging in BD patients. In the future, further properly controlled longitudinal studies are warranted to determine whether LTL changes with disease status or medication use in BD patients.

Abstract
OBJECTIVES Delays in the diagnosis and detection of bipolar disorder can lead to adverse consequences, including improper treatment and increased suicide risk. The Mood Spectrum Self-Report Measure (MOODS-SR) was designed to capture the full spectrum of lifetime mood symptomology with factor scores for depression and mania symptom constellations. The utility of the MOODS-SR as a tool to investigate homogeneous subgroups was examined, with particular focus on a possible bipolar risk subgroup. Moreover, potential patterns of differences in MOODS-SR subtypes were probed using cognitive vulnerabilities, neuropsychological functioning, and ventral striatum connectivity. METHODS K-mean cluster analysis based on factor scores of MOODS-SR was used to determine homogeneous subgroupings within a healthy and remitted depressed young adult sample (N = 86). Between-group comparisons (based on cluster subgroupings) were conducted on measures of cognitive vulnerabilities, neuropsychological functioning, and ventral striatum rs-fMRI connectivity. RESULTS Three groups of participants were identified: one with minimal symptomology, one with moderate primarily depressive symptomology, and one with more severe manic and depressive symptomology. Differences in impulsivity, neuroticism, conscientiousness, facial perception accuracy, and rs-fMRI connectivity exist between moderate and severe groups. CONCLUSIONS Within a sample of people with and without depression histories, a severe subgroup was identified with potentially increased risk of developing bipolar disorder through use of the MOODS-SR. This small subgroup had higher levels of lifetime depression and mania symptoms. Additionally, differences in traits, affective processing, and connectivity exist between those with a more prototypic unipolar subgrouping and those with potential risk for developing bipolar disorder.

Abstract
The Bipolar Spectrum Diagnostic Scale (BSDS) is widely validated and used as a screening tool for bipolar disorder. However, there is no BSDS validated version for its use in Mexican population. The aim of the present study was to examine the BSDS diagnostic capacity, and to evaluate its criterion validity and internal consistency for its use in Mexican psychiatric patients. We recruited 200 patients who attended the psychiatric outpatient service of a Mental Health Specialized Hospital and were screened for bipolar disorder using BSDS. To determine the cut-off point, sensitivity and specificity, we used the SCID-I diagnosis as the gold standard in 100 participants with bipolar disorder and 100 with major depression. Internal consistency according to Cronbach's coefficient alpha was .81. The area under ROC curve for the overall discriminability of BSDS against the criterion of SCID-I for bipolar disorder was .90. Finally, a cut-off value of 12 reached the most stable sensitivity and specificity, with predictive powers higher than .80. In conclusion, the properties of the scale including internal consistency, sensitivity and specificity, make of BSDS a valuable instrument for screening bipolar disorder in Mexican psychiatric population.

Abstract
Borderline personality disorder (BPD) is a chronic psychiatric disorder characterized by pervasive affective instability, self-image disturbances, impulsivity, marked suicidality, and unstable interpersonal relationships as the core dimensions of psychopathology underlying the disorder. Across a wide range of situations, BPD causes significant impairments. Patients with BPD suffer considerable morbidity and mortality compared with other populations. Although BPD is more widely studied than any other personality disorder, it is not understood sufficiently. This paper briefly reviews the recent evidence on the prevalence, etiology, comorbidity, and treatment approaches of borderline personality disorder (BPD) by examining published studies, and aims to offer a more coherent framework for the understanding and management of borderline personality disorder.
