Dosage effects of psychodynamic and schema therapy in people with comorbid depression and personality disorder: four-arm pragmatic randomised controlled trial.

Higher intensity of psychotherapy might improve treatment outcome in depression, especially in those with comorbid personality disorder. To compare the effects of 25 individual sessions (weekly) of two forms of psychotherapy - short-term psychoanalytic supportive psychotherapy (SPSP) and schema therapy - with the same treatments given for 50 sessions (twice weekly) in people with depression and personality disorder. Trial registration: NTR5941. We conducted a pragmatic, double-randomised clinical trial and, over 37 months, recruited 246 adult out-patients with comorbid depression/dysthymia and personality disorder. A 2 × 2 factorial design randomised participants to 25 or 50 sessions of SPSP or schema therapy. The primary outcome was change in depression severity over 1 year on the Beck Depression Inventory II (BDI-II). Secondary outcomes were remission both of depression and personality disorder. Compared with 25 sessions, participants who received 50 sessions showed a significantly greater decrease in depressive symptoms over time (time × session dosage, P < 0.001), with a mean difference of 5.6 BDI points after 1 year (d = -0.53, 95% CI -0.18 to 0.882, P = 0.003). Remission from depression was also greater in the 50-session group (74% v. 58%, P = 0.025), as was remission of personality disorder (74% v. 56%, P = 0.010). Greater intensity of psychotherapy leads to better outcomes of both depression and personality status in people with comorbid depression and personality disorder.

Emerging Outlook on Personalized Neuromodulation for Depression: Insights from Tractography-Based Targeting

BackgroundDeep brain stimulation (DBS) has shown individual promise in treating treatment resistant depression (TRD), but larger-scale trials have been less successful. Here, we create the largest meta-analysis with individual patient data (IPD) to date to explore if the use of tractography enhances the efficacy of DBS for TRD. MethodsWe systematically reviewed 1823 articles, selecting 32 that contributed data from 366 patients. We stratified the IPD based on stimulation target and use of tractography. Utilizing two-way type III Analysis of Variance (ANOVA), Welch Two Sample t-tests, and mixed-effects linear regression models, we evaluated changes in depression severity 9-15 months post-surgery (1-Y) and at last follow-up (LFU) (4 weeks – 8 years) as assessed by depression scales. ResultsTractography was used for medial forebrain bundle (MFB, n=17/32), subcallosal cingulate (SCC, n=39/241), and ventral capsule/ventral striatum (VC/VS, n=3/41) targets; and not used for bed nucleus of stria terminalis (n=11), lateral habenula (n=10), and inferior thalamic peduncle (n=1). Across all patients, tractography significantly improved mean depression scores at 1-Y (p<0.001) and LFU (p=0.009). Within the target cohorts, tractography improved depression scores at 1-Y for both MFB and SCC, though significance was only met at the alpha = 0.1 level (SCC: β=15.8%, p=0.09; MFB: β=52.4%, p=0.10). Within the tractography cohort, MFB with tractography patients showed greater improvement than those with SCC with tractography (72.42±7.17% versus 54.78±4.08%) at 1-Y (p=0.044). ConclusionsOur findings underscore the promise of tractography in DBS for TRD as a methodology for personalization of therapy, supporting its inclusion in future trials.

Evaluating the efficacy and mechanisms of a ketogenic diet as adjunctive treatment for people with treatment-resistant depression: A protocol for a randomised controlled trial

BackgroundOne-third of people with depression do not respond to antidepressants, and, after two adequate courses of antidepressants, are classified as having treatment-resistant depression (TRD). Some case reports suggest that ketogenic diets (KDs) may improve some mental illnesses, and preclinical data indicate that KDs can influence brain reward signalling, anhedonia, cortisol, and gut microbiome which are associated with depression. To date, no trials have examined the clinical effect of a KD on TRD. Methodsand analysis DIME is a proof-of-concept randomised controlled trial to investigate the efficacy of a six-week programme of weekly dietitian counselling plus provision of KD meals, compared with an intervention involving similar dietetic contact time and promoting a healthy diet with increased vegetable consumption and reduction in saturated fat, plus food vouchers to purchase healthier items. At 12 weeks we will assess whether participants have continued to follow the assigned diet. The primary outcome is the difference between groups in the change in Patient Health Questionnaire-9 (PHQ-9) score from baseline to 6 weeks. PHQ-9 will be measured at weeks 2, 4, 6 and 12. The secondary outcomes are the differences between groups in the change in remission of depression, change in anxiety score, functioning ability, quality of life, cognitive performance, reward sensitivity, and anhedonia from baseline to 6 and 12 weeks. DIME will also assess whether changes in reward sensitivity, anhedonia, cortisol awakening response and gut microbiome may explain any changes in depression severity. DiscussionThis study will test whether a ketogenic diet is an effective intervention to reduce the severity of depression, anxiety and improve quality of life and functioning ability for people with treatment-resistant depression.

Improved clinical outcome prediction in depression using neurodynamics in an emotional face-matching functional MRI task.

Approximately one in six people will experience an episode of major depressive disorder (MDD) in their lifetime. Effective treatment is hindered by subjective clinical decision-making and a lack of objective prognostic biomarkers. Functional MRI (fMRI) could provide such an objective measure but the majority of MDD studies has focused on static approaches, disregarding the rapidly changing nature of the brain. In this study, we aim to predict depression severity changes at 3 and 6 months using dynamic fMRI features. For our research, we acquired a longitudinal dataset of 32 MDD patients with fMRI scans acquired at baseline and clinical follow-ups 3 and 6 months later. Several measures were derived from an emotion face-matching fMRI dataset: activity in brain regions, static and dynamic functional connectivity between functional brain networks (FBNs) and two measures from a wavelet coherence analysis approach. All fMRI features were evaluated independently, with and without demographic and clinical parameters. Patients were divided into two classes based on changes in depression severity at both follow-ups. The number of coherence clusters (nCC) between FBNs, reflecting the total number of interactions (either synchronous, anti-synchronous or causal), resulted in the highest predictive performance. The nCC-based classifier achieved 87.5% and 77.4% accuracy for the 3- and 6-months change in severity, respectively. Furthermore, regression analyses supported the potential of nCC for predicting depression severity on a continuous scale. The posterior default mode network (DMN), dorsal attention network (DAN) and two visual networks were the most important networks in the optimal nCC models. Reduced nCC was associated with a poorer depression course, suggesting deficits in sustained attention to and coping with emotion-related faces. An ensemble of classifiers with demographic, clinical and lead coherence features, a measure of dynamic causality, resulted in a 3-months clinical outcome prediction accuracy of 81.2%. The dynamic wavelet features demonstrated high accuracy in predicting individual depression severity change. Features describing brain dynamics could enhance understanding of depression and support clinical decision-making. Further studies are required to evaluate their robustness and replicability in larger cohorts.

How changes in depression severity and borderline personality disorder intensity are linked – a cohort study of depressed patients with and without borderline personality disorder

BackgroundBorderline personality disorder (BPD) is often complicated by comorbid major depressive episodes (MDEs), which can occur as part of major depressive disorder (MDD) or bipolar disorder (BD). Such comorbidity is related to worse outcomes in both disorders. Subsyndromal features of BPD are also common in depression. However, studies of simultaneous changes in BPD and depression severities are scarce, and their interactions are poorly understood.AimsStudying the associations between changes in BPD and depression symptoms over the course of an MDE.MethodsIn a 6-month naturalistic cohort study of MDE/BPD, MDE/MDD, and MDE/BD patients (N = 95), we measured change in BPD features between baseline and six months with the Borderline Personality Disorder Severity Index (BPDSI), an interviewer-rated instrument quantifying recent temporal frequency of BPD symptoms. We examined changes in BPD severity and their correlation with depression severity and other clinical measures and compared these across patient groups.ResultsThere were significant reductions in BPD severity, both in number of positive BPD criteria (-0.35, sd 1.38, p = 0.01672) and in BPDSI scores (-4.23, SD 6.74, p < 0.001), reflecting mainly a reduction in temporal frequency of symptoms. These were similar in all diagnostic groups. In multivariate regression models, changes in depression severity independently associated with changes in symptoms in the BDSI. This relationship was strongest in MDE/BPD patients but was not found in MDD patients without BPD.ConclusionsIn the six-month follow-up, BPD features in MDE patients alleviated mainly by decreasing temporal symptom frequency and intensity. In BPD patients with comorbid MDE, changes in both conditions are strongly correlated.

Identifying predictors of a favourable outcome for outpatients with a persistent depressive disorder treated with Cognitive Behavioural Analysis System of Psychotherapy: A prospective cohort study.

Cognitive Behavioural Analysis System of Psychotherapy (CBASP) is the first therapy specifically developed for persistent depressive disorder (PDD). This study aimed to identify predictors of favourable treatment outcome after group CBASP and assess change in depression severity over 24 weeks. A prospective cohort study was conducted in patients with PDD treated with group-CBASP. Outcomes were depression severity measured by the Inventory of Depression Severity-self-report (IDS-SR) after 6 and 12 months. Potential predictors investigated were baseline depression severity, prior antidepressant use, age, family status, income source, age of onset and childhood trauma. Multivariate logistic regression was performed to assess their effects with a ≥25% IDS-SR score decrease as the dependent variable. The IDS-SR score (range 0-84) significantly decreased from 37.78 at start to 33.45 at 6 months, an improvement which was maintained at 12 months. Having paid work and no axis I comorbidity significantly predicted favourable response. In the groups without a favourable outcome predictor a substantial percentage still showed at least partial response (16.7% and 19.2%). Source of income and axis I comorbidity were predictors of response to group-CBASP. Within the group without favourable outcome predictors, a subgroup showed at least partial response. These results suggest that group-CBASP has promise for patients who do not respond to standard treatments. Future studies should include outcome measures that take into account comorbidity and other clinically relevant changes, such as social functioning.

Ketamine in multiple treatment-resistant depressed inpatients: A naturalistic cohort study

BackgroundKetamine has emerged as an effective treatment option for patients with treatment-resistant depression. However, there is limited evidence of the benefits of ketamine in inpatients with multiple treatment resistance (MTR), who far exceed the formal criteria for treatment resistance and suffer from extensive psychiatric comorbidities. ObjectiveThe aim of this naturalistic study was to provide preliminary evidence for the use of ketamine in the treatment of MTR depression in a naturalistic inpatient setting. MethodsSeventy-seven patients (mean age 45.1 ± 13.8 years) were treated with intravenous or intranasal ketamine (1068 administrations) twice weekly for five weeks, followed by maintenance therapy if clinically indicated. Treatment effects were assessed with the BDI, and side effects were assessed by clinicians. We analyzed dose- and route of application-related changes in depression severity, response and remission rates as well as effects on suicidality and frequency of adverse events. ResultsDepression severity and suicidality decreased in the acute treatment phase and these changes persisted during the maintenance therapy phase. A total of 28.9 % of the patients met the criteria for response, and 15 % met the criteria for remission. The initial treatment response was highly predictive of the outcome at the end of the acute treatment phase. None of the reported side effects required medical intervention. High-dose intravenous ketamine (0.75–1 mg/kg) resulted in the most pronounced clinical effects. LimitationsThis observational, retrospective, and naturalistic study may be subject to bias and did not allow control of external variables. ConclusionsWe outlined a clinically feasible, high-dose ketamine treatment regimen for hospitalized patients with MTR depression.

Predicting a short-term change of suicidal ideation in inpatients with depression: An ecological momentary assessment

IntroductionPatients with depression often require inpatient treatment due to their high suicide risk. Ecological momentary assessment (EMA) studies have shown that suicidal ideation (SI) fluctuates over time. As affective instability and psychological pain (PP) are common experiences in borderline personality disorder (BPD), often comorbid with depression, we examined factors predicting short-term changes of SI in depressive inpatients with or without BPD. MethodsPsychiatric inpatients with depression with (N = 30) or without (N = 37) comorbid BPD assessed their anxiety, PP, severity of depression, SI, and hopelessness three times daily using visual analogue scales. Multilevel regression models were estimated. ResultsAltogether 4320 EMA observations, spanning on average 3.4 successive days, were collected. Only severity of depression (β = 0.19; [95 % CI = 0.06, 0.32]) and previous SI (β = 0.32; [95 % CI = 0.23, 0.41]) predicted near-future SI within several hours. PP predicted near-future SI in inpatients with depression and BPD (β = 0.28; [95 % CI = 0.11, 0.46]), but not in patients without BPD. LimitationsThe follow-up data represents only the first days of hospitalization. The context of the EMA is the acute psychiatric ward, affecting generalizability to outpatients. ConclusionsShort-terms changes in SI are predicted by changes in severity of depression and previous SI in depressed inpatients without BPD, and also by changes in PP in depressed inpatients with BPD. As SI and its risk factors may oscillate within a time scale of hours, frequent monitoring of momentary severity of depression, PP, and SI may be warranted in inpatient settings.

Effectiveness of Schema Therapy versus Cognitive Behavioral Therapy versus Supportive Therapy for Depression in Inpatient and Day Clinic Settings: A Randomized Clinical Trial

Introduction: Schema therapy (ST) reduces depressive symptoms, but clinical trials have not investigated its effectiveness for patients suffering from severe forms of depression and high rates of comorbidities. There is high demand for exploring and improving treatments for this patient group. The objective of the current study was to evaluate whether ST is more effective than individual supportive therapy (IST) and noninferior compared with cognitive behavioral therapy (CBT) in treating depression. Methods: For this clinical trial, medicated patients were recruited in inpatient and day clinic settings. The major inclusion criteria were age between 18 and 75 years and primary diagnosis of depression without psychotic symptoms. A total of 292 participants were randomized to ST, CBT, or IST and received 7 weeks of psychotherapy (up to 14 individual and 14 group sessions). The primary outcome was change in depression severity after treatment measured by Beck Depression Inventory-II. Primary test for efficacy was superiority of ST over IST. Secondary test was noninferiority of ST compared with CBT. Multilevel modeling was conducted. The results at 6-month follow-up were explored. Results: Across treatment, ST was not superior to IST. Secondary outcome analyses and completer analyses showed similar results. However, ST showed clinically relevant noninferiority compared with CBT. Conclusion: ST for depression as part of a psychiatric care program showed clinical noninferiority compared to CBT, without being superior to IST. ST represents a potentially useful addition to the therapeutic repertoire for the treatment of depression but its efficacy, including long-term efficacy, should be evaluated further.

The association of changes in depression severity after the onset of the COVID-19 pandemic and viral nonsuppression among people with HIV.

This study sought to characterize changes in depressive symptom severity during the COVID-19 pandemic and the association of these changes with HIV viral nonsuppression among people with HIV (PWH). A clinical cohort study. We included PWH in the Johns Hopkins HIV Clinical Cohort who completed the Patient Health Questionnaire 8 (PHQ-8) prepandemic (1 March 2018 to 28 February 2020) and during the COVID-era (1 September 2020 to 28 February 2022). PWH were classified according to depression severity categories prepandemic and during the COVID-era as: consistently depressed (prepandemic PHQ-8 >4 and no change in severity category); consistently nondepressed (prepandemic PHQ-8 ≤4 and no change in severity category); worsened (changed to a higher severity category) and; improved (change to a lower severity category). The association between changes in depressive symptom severity and viral nonsuppression (HIV RNA >200 copies/ml on the earliest viral load measured 7 days before to 12 months after the COVID-era PHQ-8 survey) was assessed using multivariable logistic regression. Of 793 PWH, mean age was 56 (SD 10) years, 60% were male individuals and 88% were Black. After the onset of the pandemic, 60% were consistently nondepressed, 9% were consistently depressed, 15% worsened and 16% improved. PWH who worsened had 2.47 times the odds of viral nonsuppression (95% CI: 1.09-5.55) compared with the nondepressed group. Associations among other groups were not statistically significant. Worsening depression during the COVID-era was associated with HIV viral nonsuppression. Strategies to monitor and address depression among PWH may contribute to reduced risk of viral nonsuppression.

Brain ventricle and choroid plexus morphology as predictor of treatment response in major depression: Findings from the EMBARC study

Recent observations suggest a role of the volume of the cerebral ventricle volume, corpus callosum (CC) segment volume, in particular that of the central-anterior part, and choroid plexus (CP) volume for treatment resistance of major depressive disorder (MDD). An increased CP volume has been associated with increased inflammatory activity and changes in the structure of the ventricles and corpus callosum. We attempt to replicate and confirm that these imaging markers are associated with clinical outcome in subjects from the EMBARC study, as implied by a recent pilot study. The EMBARC study is a placebo controlled randomized study comparing sertraline vs. placebo in patients with MDD to identify biological markers of therapy resistance. Association of baseline volumes of the lateral ventricles (LVV), choroid plexus volume (CPV) and volume of segments of the CC with treatment response after 4 weeks treatment was evaluated. 171 subjects (61 male, 110 female) completed the 4 week assessments; gender and age were taken into account for this analyses. As previously reported, no treatment effect of sertraline vs. placebo was observed, therefore the study characterized prognostic markers of response in the pooled population. Change in depression severity was identified by the ratio of the Hamilton-Depression rating scale 17 (HAMD-17) at week 4 divided by the HAMD-17 at baseline (HAMD-17 ratio). Volumes of the lateral ventricles and choroid plexi were positively correlated with the HAMD-17 ratio, indication worse outcome with larger ventricles and choroid plexus volumes, whereas the volume of the central-anterior corpus callosum was negatively correlated with the HAMD-17 ratio. Responders (n = 54) had significantly smaller volumes of the lateral ventricles and CP compared to non-responders (n = 117), whereas the volume of mid-anterior CC was significantly larger compared to non-responders (n = 117), confirming our previous findings. In an exploratory way associations between enlarged LVV and CPV and signs of lipid dysregulation were observed. In conclusion, we confirmed that volumes of lateral ventricles, choroid plexi and the mid-anterior corpus callosum are associated with clinical improvement of depression and may be indicators of metabolic/inflammatory activity.

Effect of non-invasive spinal cord stimulation in unmedicated adults with major depressive disorder: a pilot randomized controlled trial and induced current flow pattern.

Converging theoretical frameworks suggest a role and a therapeutic potential for spinal interoceptive pathways in major depressive disorder (MDD). Here, we aimed to evaluate the antidepressant effects and tolerability of transcutaneous spinal direct current stimulation (tsDCS) in MDD. This was a double-blind, randomized, sham-controlled, parallel group, pilot clinical trial in unmedicated adults with moderate MDD. Twenty participants were randomly allocated (1:1 ratio) to receive "active" 2.5 mA or "sham" anodal tsDCS sessions with a thoracic (anode; T10)/right shoulder (cathode) electrode montage 3 times/week for 8 weeks. Change in depression severity (MADRS) scores (prespecified primary outcome) and secondary clinical outcomes were analyzed with ANOVA models. An E-Field model was generated using the active tsDCS parameters. Compared to sham (n = 9), the active tsDCS group (n = 10) showed a greater baseline to endpoint decrease in MADRS score with a large effect size (-14.6 ± 2.5 vs. -21.7 ± 2.3, p = 0.040, d = 0.86). Additionally, compared to sham, active tsDCS induced a greater decrease in MADRS "reported sadness" item (-1.8 ± 0.4 vs. -3.2 ± 0.4, p = 0.012), and a greater cumulative decrease in pre/post tsDCS session diastolic blood pressure change from baseline to endpoint (group difference: 7.9 ± 3.7 mmHg, p = 0.039). Statistical trends in the same direction were observed for MADRS "pessimistic thoughts" item and week-8 CGI-I scores. No group differences were observed in adverse events (AEs) and no serious AEs occurred. The current flow simulation showed electric field at strength within the neuromodulation range (max. ~0.45 V/m) reaching the thoracic spinal gray matter. The results from this pilot study suggest that tsDCS is feasible, well-tolerated, and shows therapeutic potential in MDD. This work also provides the initial framework for the cautious exploration of non-invasive spinal cord neuromodulation in the context of mental health research and therapeutics. The underlying mechanisms warrant further investigation. Clinicaltrials.gov registration: NCT03433339 URL: https://clinicaltrials.gov/ct2/show/NCT03433339 .

Meditation-Based Lifestyle Modification in Mild-to-Moderate Depression: Outcomes and Moderation Effects of Spirituality.

Objective: Understanding the relevance of religion or spirituality (R/S) in the treatment of mental disorders is central to clinical and academic psychiatry. In this secondary analysis, associations of R/S with depression were investigated with respect to a new second-generation mindfulness-based intervention, the Meditation-Based Lifestyle Modification (MBLM) program. Methods: Different aspects of spirituality, spiritual coping, and spiritual engagement were assessed in 81 patients with a diagnosis of mild-to-moderate depression. Treatment effects on R/S postscores and predictor and moderation effects of depression severity and stress change-scores were evaluated at 8 weeks (MBLM vs. CONTROL [drug continuation therapy] vs. TAU [inpatient treatment as usual]) and 6 months (TAU+MBLM vs. TAU). Results: At both time points, significant differences between MBLM versus TAU and CONTROL were found in a range of spiritual outcomes, most of them with a medium-to-large effect size and in favor of MBLM. Baseline interest in spirituality (p = 0.001) and baseline spiritual mind-body practice (p = 0.017) were identified as independent predictors of change in depression severity at 6 months. Moreover, moderation analyses found that patients reporting often/regular spiritual mind-body practice at 6 months did not benefit differently from TAU+MBLM versus TAU (p = 0.437) regarding their change in depression severity and stress, while those reporting no/seldom spiritual mind-body practice at 6 months benefited significantly worse from TAU than from TAU+MBLM (p = 0.002). Conclusions: Participation in the MBLM program resulted in significantly greater increases in spirituality in depressed patients than standard therapy. Interest in spirituality and engagement in spiritual mind-body practices at baseline were positive predictors of clinical outcome in both groups. Patients of any group who regularly performed spiritual mind-body practices benefited equally in terms of antidepressant outcomes, underlining the benefit of these practices within a general therapeutic framework. ClinicalTrials.gov Identifier: NCT03652220.

Antidepressant effects of dexmedetomidine compared with ECT in patients with treatment-resistant depression

ObjectiveThis pilot study was designed to investigate the antidepressant effects of dexmedetomidine (DEX), a selective α2-adrenergic receptor agonist, in patients with treatment-resistant depression (TRD). The antidepressant effects of dexmedetomidine was compared with ECT, which is widely used in clinical practice for treatment of patients with TRD. MethodsSeventy six patients with TRD were randomly assigned to receive 10 sessions of DEX infusions or electroconvulsive therapy (ECT) treatment. The primary outcome was the changes of depression severity determined by the improvement of 24-item Hamilton Depression Rating Scale (HDRS-24). The second outcomes were the rates of therapeutic response (reduction in HDRS-24 ≥ 50 %) and remission (HDRS-24 ≤ 10 and reduction in HDRS-24 ≥ 60 %) at posttreatment and after 3 months of follow-up visits. ResultsWe found that 10 sessions of DEX infusions or ECT treatments significantly improved HDRS-24 scores at posttreatment and after 3 months of follow-up visits compared with the baseline. In addition, there was no significant difference between DEX infusions and ECT treatments regarding HDRS-24 at these evaluating points. Furthermore, the depression severity dropped to mild after 2 sessions of DEX infusion. In contrast, at least 6 sessions of ECT treatment were needed to achieve a same level. Finally, the rates of therapeutic response and remission were comparable between the two groups. No serious adverse events were observed. ConclusionsBased on current published evidence, we conclude that DEX exhibits rapid and durable antidepressant properties similar to ECT but with fewer side effects.

State-dependent alterations of implicit emotional dominance during binocular rivalry in subthreshold depression.

Binocular rivalry, a visual perception phenomenon where two or more percepts alternate every few seconds when distinct stimuli are presented to the two eyes, has been reported as a biomarker in several psychiatric disorders. It is unclear whether abnormalities of binocular rivalry in depression could occur when emotional rivaling stimuli are used, and if so, whether an emotional binocular rivalry test could provide a trait-dependent or state-dependent biomarker. In the current study, 34 individuals with subthreshold depression and 31 non-depressed individuals performed a binocular rivalry task associated with implicit emotional processing. Participants were required to report their perceived orientations of the rival gratings in the foreground and to neglect emotional face stimuli in the background. The participants were retested after an approximately 4-month time interval. Compared to the non-depressed group, the subthreshold depression group showed significantly longer perceptual dominance durations of the grating with emotional faces as the background (i.e., implicit emotional dominance) at the initial assessment. However, the abnormality was not found at the follow-up assessment. More importantly, we found smaller changes in depressive severity at the follow-up assessment for individuals displaying longer emotional dominance at the initial assessment than for individuals with weaker emotional dominance. The current emotional binocular rivalry test may provide an objective, state-dependent biomarker for distinguishing individuals with subthreshold depression from non-depressed individuals.

The Impact of Post-Stroke Depressive Symptoms on Cognitive Performance in Women and in Men: A 4 Month Prospective Study.

Background: Depressive symptoms have been associated with cognitive impairment after stroke, and women may be specifically affected. Objective: The aim of this study was to investigate gender-specific characteristics in the relationship between changes in depression severity and changes in cognitive performance after stroke. Methods: We prospectively evaluated 73 patients without a previous history of depression in the first and fourth months after a first ischemic stroke. The severity of depressive symptoms was assessed using the 31-item version of the Hamilton Rating Scale for Depression, and executive function, attention, working memory, and verbal fluency were assessed using a neuropsychological battery. Results: We included 46 (63.0%) men and 27 (36.9%) women, with mean ages of 55.2 (SD ± 15.1) and 46.8 (SD ± 14.7) years, respectively. We found significant improvement in the digit span forward and Stroop dots from month 1 to month 4 post stroke for both men and women. Women, but not men, presented a correlation between changes in phonemic verbal fluency and changes in the 31-item version of the Hamilton Rating Scale for Depression scores. Improvement in depression was correlated with improvement in verbal fluency, and worsening in depression was correlated with worsening in verbal fluency. Conclusions: Our results suggest that women might be more vulnerable to the relationship between depressive symptoms and cognitive performance, and improvement of depression may be necessary for women's improvement in phonemic verbal fluency from the first to the fourth month after a stroke. We did not adjust the results for multiple comparisons. Thus, our findings might be considered preliminary, and confirmatory studies, also focusing on specific characteristics of women that could explain these differences, are warranted.

Borderline personality disorder and depression severity predict suicidal outcomes: A six-month prospective cohort study of depression, bipolar depression, and borderline personality disorder.

Suicide risk is high in patients with major depressive disorder (MDD), bipolar disorder (BD) and borderline personality disorder (BPD). Whether risk levels of and risk factors for suicidal ideation (SI) and suicide attempts (SA) are similar or different in these disorders remains unclear, as few directly comparative studies exist. The relationship of short-term changes in depression severity and SI is underinvestigated, and might differ across groups, for example, between BPD and non-BPD patients. We followed, for 6 months, a cohort of treatment-seeking, major depressive episode (MDE) patients in psychiatric care (original n = 124), stratified into MDE/MDD, MDE/BD and MDE/BPD subcohorts. We examined risks of suicide-related outcomes and their risk factors prospectively. We examined the covariation of SI and depression over time with biweekly online modified Patient Health Questionnaire 9 surveys and analysed this relationship through multi-level modelling. Risk of SA in BPD (22.2%) was higher than non-BPD (4.23%) patients. In regression models, BPD severity was correlated with risk of SA and clinically significant SI. During follow-up, mean depression severity and changes in depression symptoms were associated with SI risk regardless of diagnosis. Concurrent BPD in depression seems predictive for high risk of SA. Severity of BPD features is relevant for assessing risk of SA and SI in MDE. Changes in depressive symptoms indicate concurrent changes in risk of SI. BPD status at intake can index risk for future SA, whereas depressive symptoms appear a useful continuously monitored risk index.

Manifestation of depression in speech overlaps with characteristics used to represent and recognize speaker identity

The sound of a person’s voice is commonly used to identify the speaker. The sound of speech is also starting to be used to detect medical conditions, such as depression. It is not known whether the manifestations of depression in speech overlap with those used to identify the speaker. In this paper, we test the hypothesis that the representations of personal identity in speech, known as speaker embeddings, improve the detection of depression and estimation of depressive symptoms severity. We further examine whether changes in depression severity interfere with the recognition of speaker’s identity. We extract speaker embeddings from models pre-trained on a large sample of speakers from the general population without information on depression diagnosis. We test these speaker embeddings for severity estimation in independent datasets consisting of clinical interviews (DAIC-WOZ), spontaneous speech (VocalMind), and longitudinal data (VocalMind). We also use the severity estimates to predict presence of depression. Speaker embeddings, combined with established acoustic features (OpenSMILE), predicted severity with root mean square error (RMSE) values of 6.01 and 6.28 in DAIC-WOZ and VocalMind datasets, respectively, lower than acoustic features alone or speaker embeddings alone. When used to detect depression, speaker embeddings showed higher balanced accuracy (BAc) and surpassed previous state-of-the-art performance in depression detection from speech, with BAc values of 66% and 64% in DAIC-WOZ and VocalMind datasets, respectively. Results from a subset of participants with repeated speech samples show that the speaker identification is affected by changes in depression severity. These results suggest that depression overlaps with personal identity in the acoustic space. While speaker embeddings improve depression detection and severity estimation, deterioration or improvement in mood may interfere with speaker verification.

The Role of Negative Posttraumatic Cognitions in the Treatment of Patients with Post-traumatic Stress Disorder

BackgroundNegative post-traumatic cognitions (PTC) are a risk factor for the development and maintenance of post-traumatic stress disorder (PTSD). PTC have further been linked to symptoms of depression, anxiety, and emotion regulation (ER). We investigated the role of PTC in the treatment of PTSD patients.MethodWe analyzed data from 339 inpatients (279 female) who received inpatient trauma-focused treatment for eight to twelve weeks. PTC, symptoms of PTSD, depression, anxiety, and ER were assessed at admission and discharge. PTC assessment included negative cognitions about the self, the world, and self-blame.ResultsThe results show that all symptoms and ER, and all PTC except for self-blame, decreased during treatment. Only baseline level of PTC about the self was related to changes in depression severity. The other baseline levels of PTC were not related to any changes in symptom severity. Changes in PTC about the self were related to changes in all symptoms and ER. Changes in PTC about the world were only linked to symptoms of PTSD. Changes in self-blame were only associated with symptoms of re-experiencing.ConclusionsOur findings suggest that PTC about the self play a more general and PTC about the world a more specific role in the treatment of PTSD. Further research is needed to clarify the role of self-blame in the treatment.

The rapid change in mental health among college students after introduction of on-campus quarantine during the 2022 Shanghai COVID-19 lockdown.

Among the various impacts of disasters in terms of emotions, quarantine has been proven to result in significant increases in mental health problems. Studies of psychological resilience during outbreaks of epidemics tend to focus on long-term social quarantine. In contrast, insufficient studies have been conducted examining how rapidly negative mental health outcomes occur and how these outcomes change over time. We evaluated the time course of psychological resilience (over three different phases of quarantine) among students at Shanghai Jiao Tong University to investigate the influence of unexpected changes on college students. An online survey was conducted from 5 to 7 April 2022. A structured online questionnaire was administered using a retrospective cohort trial design. Before 9 March (Period 1), individuals engaged in their usual activities without restrictions. From 9 to 23 March (Period 2), the majority of students were asked to remain in their dormitories on campus. From 24 March to early April (Period 3), restrictions were relaxed, and students were gradually allowed to participate in essential activities on campus. We quantified dynamic changes in the severity of students' depressive symptoms over the course of these three periods. The survey consisted of five sets of self-reported questions: demographic information, lifestyle/activity restrictions, a brief mental health history, COVID-19-related background, and the Beck Depression Inventory, second edition. A total of 274 college students aged 18-42 years (mean = 22.34; SE = 0.24) participated in the study (58.39% undergraduate students, 41.61% graduate students; 40.51% male, 59.49% female). The proportion of students with depressive symptoms was 9.1% in Period 1, 36.1% in Period 2, and 34.67% in Period 3. Depressive symptoms increased notably with the introduction of the quarantine in Periods 2 and 3. Lower satisfaction with the food supplied and a longer duration of physical exercise per day were found to be positively associated with changes in depression severity in Periods 2 and 3. Quarantine-related psychological distress was more evident in students who were in a romantic relationship than in students who were single. Depressive symptoms in university students rapidly increased after 2 weeks of quarantine and no perceptible reversal was observed over time. Concerning students in a relationship, ways to take physical exercise and to relax should be provided and the food supplied should be improved when young people are quarantined.
