Background Emotionally Unstable Personality Disorder (EUPD) is characterised by emotional dysregulation, unstable self-identity, interpersonal difficulties, dissociation, and a high prevalence of non-suicidal self-injury (NSSI). Mental imagery plays a role in emotion processing and autobiographical memory. Yet little is known about the relation between voluntary visual imagery and self-harm in EUPD. The study aimed to examine the imagery characteristics, including visual imagery vividness and synaesthetic-like experiences, and their association with NSSI in EUPD. Method Forty adults aged 18-45 years meeting ICD-10 Diagnostic Criteria for Research (ICD-10 DCR) for EUPD were recruited through purposive sampling. Visual imagery was assessed using the Vividness of Visual Imagery Questionnaire-2 (VVIQ-2). NSSI and its functions were assessed using the Inventory of Statements About Self-Injury (ISAS). Synaesthesia-like experiences were screened using a seven-item questionnaire developed for the study. Group comparisons were performed using independent-samples t-tests, and correlations were assessed using Pearson's correlation coefficient. Results Twenty-nine patients (72.5%) with EUPD had NSSI. Participants with NSSI had significantly higher mean VVIQ-2 scores than those without NSSI (118.48 +/- 24.81 vs. 93.36 +/- 35.66; p = 0.016; Cohen's d = 0.89). VVIQ-2 scores correlated positively with intrapersonal ISAS functions (r = 0.38, p = 0.015) but not interpersonal functions (r = 0.19, p = 0.22). Three participants (7.5%) demonstrated imagery scores compatible with probable hyperphantasia. Four participants reported synaesthesia-like experiences. Conclusions Greater visual imagery was associated with non-suicidal self-harm in patients with EUPD. Imagery vividness was predominantly associated with intrapersonal functions of non-suicidal self-harm, particularly affect regulation, rather than interpersonal motivations. These findings suggest that visual imagery may represent a previously under-recognized cognitive factor contributing to emotional dysregulation and self-injurious behaviour in EUPD. Assessment of imagery characteristics may have clinical relevance when designing psychotherapeutic interventions for EUPD.

Background: Emotion dysregulation is a core feature of bipolar disorder (BD), yet its behavioral expression during depressive episodes, and potential differences between its types, BD-I and BD-II, remain unclear. This study used automated facial-expression analysis during naturalistic affective film viewing to examine subtype-specific and context-dependent emotional responding in bipolar depression. Methods: The sample included 135 participants: 69 healthy controls and 66 patients with BD (BD-I, 23; BD-II, 43). Participants viewed nine emotionally evocative film clips spanning negative, positive, neutral, and socially threatening contexts, while their facial expressions were continuously recorded and quantified using computer vision-based facial-expression analysis. Results: Patients with BD-I showed a distinct, context-dependent facial-expression profile, characterized by greater negative responses across multiple contexts than other groups. Specifically, they showed increased sadness during sad, reward, and amusing clips, and elevated anger during sad and neutral clips. In socially threatening contexts, BD-I participants showed a multivalent pattern of elevated anger, fear, and joy, suggesting poorly coordinated or context-incongruent affective expression. In contrast, BD-II participants did not differ significantly from healthy controls on any emotion, despite depressive symptom severity comparable to BD-I participants. Conclusions: These findings suggest that facial-expression patterns in bipolar depression differ across subtypes. BD-I may be characterized by heightened negative reactivity and altered context-appropriate modulation of emotional expression, whereas BD-II may not show comparable alterations in overt facial output. Automated facial-expression analysis during naturalistic stimulation may provide a useful behavioral marker for characterizing subtype-specific affective disturbance in bipolar depression and related psychopathology.

Purpose This study aimed to examine the association between screen time and depressive symptoms among Chinese college students, and to investigate the mediating roles of sleep quality and emotion regulation in this relationship. Furthermore, a serial mediation model was constructed to elucidate the underlying psychological mechanisms linking screen exposure to depression. Methods A stratified cluster sampling method was employed to recruit 10,999 college students for a cross-sectional questionnaire survey. Data were collected on screen time, sleep quality, emotion regulation ability, and depressive symptoms. Descriptive statistics, correlation analyses, and regression analyses were conducted using SPSS 26.0 A serial mediation model was tested using the PROCESS macro (Model 6), and bootstrapping procedures were applied to estimate the significance of indirect effects. Results Correlation analyses indicated that screen time was significantly positively associated with depressive symptoms (r = 0.16, p < 0.01) and sleep quality (r = 0.15, p < 0.01), and significantly negatively associated with emotion regulation (r = -0.13, p < 0.01). Sleep quality was positively correlated with depressive symptoms (r = 0.31, p < 0.01), whereas emotion regulation was negatively correlated with depressive symptoms (r = -0.42, p < 0.01). Regression analyses further showed that screen time significantly positively predicted depressive symptoms ({beta} = 0.712, p < 0.001), positively predicted sleep quality ({beta} = 0.217, p < 0.001), and negatively predicted emotion regulation ({beta} = -0.085, p < 0.001). In addition, both sleep quality ({beta} = 1.318, p < 0.001) and emotion regulation ({beta} = -0.424, p < 0.001) were significant predictors of depressive symptoms. Mediation analyses demonstrated that sleep quality significantly mediated the association between screen time and depressive symptoms (95% CI [0.239, 0.332]), as did emotion regulation (95% CI [0.269, 0.416]). Moreover, a significant serial mediation effect of sleep quality and emotion regulation was observed in the relationship between screen time and depressive symptoms (95% CI [0.082, 0.117]). Conclusion Screen time is significantly associated with depressive symptoms among college students, with sleep quality and emotion regulation serving as important mediating mechanisms. Extended screen exposure may be linked to higher levels of depressive symptoms by impairing sleep quality and weakening emotion regulation capacity.

Post-traumatic stress disorder (PTSD) is associated with high rates of comorbid personality disorders, which may contribute to PTSD severity. Among veterans with PTSD, obsessive compulsive personality disorder (OCPD) is common, with reported prevalence estimates ranging from 7-44%. Despite this, the relationship between OCPD traits and PTSD severity remains poorly understood. This retrospective, cross-sectional study examined associations between PTSD severity and OCPD traits in a naturalistic sample of 99 Veterans evaluated by a single clinician in a PTSD/Trauma Recovery Services clinic. PTSD symptoms were measured with the PTSD Checklist for DSM-V (PCL-5), and OCPD traits were measured with the Pathological Obsessive-Compulsive Personality Scale (POPS). Relationships between these two constructs were examined using Pearson correlations. Overall PTSD severity was significantly and positively correlated with total OCPD traits (r = 0.46, p < 0.001). Among OCPD domains, maladaptive perfectionism showed the strongest association with PTSD severity (r = 0.44, p <.001), followed by emotional overcontrol and reluctance to delegate (both r = .38, p < .01), rigidity (r = .35, p < .01), and difficulty with change (r = .28, p < .05). These findings suggest OCPD traits impact PTSD symptom burden in veterans, warranting further research and clinical attention.

Background Psychiatric comorbidities commonly have a negative impact on epilepsy outcomes. However, they are continuously ignored in routine epilepsy care, with focus directed more towards seizure control. There is paucity of data on the burden of psychiatric morbidity among those living with epilepsy in Kenya. This study sought to determine the prevalence and associated factors of psychiatric morbidity among patients living with epilepsy at a tertiary referral hospital in Western Kenya. Methods This was a descriptive cross-sectional study. Consecutive sampling was used to recruit participants, with a sample size of 278. Data were collected using a structured pretested sociodemographic and clinical characteristics questionnaire, and the Mini International Neuropsychiatric Interview (MINI), and analyzed using STATA version 16. Pearson Chi-square test/Fishers Exact test and logistic regression were used to assess relationships at bivariate and multivariate levels respectively. Results The prevalence of psychiatric morbidity was 52.2%. Major depressive disorder was the most prevalent (36%), followed by anxiety disorders (26.2%), psychotic disorders (16.9%), and suicidality (15.1%). Casual/self-employment (aOR=2.590, p=0.020), seizure-related physical trauma (aOR=4.032, p=0.004), antiepileptic polytherapy (aOR=4.280, p=0.001), frequent seizures (aOR=3.801, p<0.001), and comorbid medical conditions (aOR=5.478, p=0.047) were independent predictors of psychiatric morbidity. Having attained a tertiary level of education was protective against psychiatric morbidity (aOR=0.221, p=0.036). Conclusion More than half of the patients living with epilepsy had at least one psychiatric comorbidity. Routine psychiatric screening and integration of mental health services in epilepsy care is essential to improve clinical outcomes.

Background Functional neurological disorder (FND), one of the most common neurological conditions, affects women almost twice as frequently as men. The reasons for this are unknown, and there has been minimal research into how physiological and pathological features of women's health interact with symptoms of FND. Methods We conducted an online survey assessing the effect of several aspects of women's health with the severity of symptoms of FND. Results 484 people completed the survey. Among the 223 who had regular or fairly regular menstrual cycles, a strong difference across the menstrual cycle was seen, with symptoms at their best in the follicular phase, worsening in the luteal phase, and worst in the pre-menstrual period and the menses. This effect was not moderated by a proxy measure of pre-menstrual dysphoric disorder (PMDD). Participants who were taking the combined oral contraceptive (COC, n=43) and progesterone-based contraception (n=80) were more likely to report symptom improvement from starting the medication than worsening. When compared to menstruating participants who were not taking the COC, participants taking the COC reported less worsening in their symptoms of FND in the luteal, pre-menstrual, and menstrual phases. Of the 99 women who had passed menopause since developing FND, 76% reported worsening of their FND symptoms after menopause. Discussion This study demonstrates interactions between several aspects of women's health and symptoms of FND. The observed pattern of symptom fluctuation across hormonal states suggests a potential modulatory role of oestrogen, warranting further targeted investigation.

Background For people with bipolar disorder, recovery from manic or mixed episodes is frequently complicated by depression. Depression after manic/mixed episodes may occur within a broader episode sequence pattern of mania-depression-euthymic interval, proposed as a bipolar disorder subtype for which lithium is effective. However, the window of risk for mania/mixed-to-depression transition remains unclear, as is the relationship with clinical factors and outcomes. Methods In this retrospective cohort study, we identified a cohort of 10,437 people with bipolar disorder (42,314 mood episodes; 90,727 person-years) within the NeuroBlu health record database (United States) with records from 1959 to 2025. We quantified the transition time from manic/mixed episodes to depression, and investigated associations with clinical features, medications and outcomes. Outcomes 25% of all manic episodes and 22% of all mixed episodes transitioned to depression within 1 month: an incidence >11-times higher than the overall per-month depression rate. By 6 months, the depression transition rate had plateaued. Short depression transition time ([&le;]1 month) was associated with previous short transition times (post-mania RR=3.08, 95%CI: 2.65-3.58; post-mixed RR=2.52, 95%CI: 2.12-3.00), higher manic/mixed severity (post-mania RR=1.30 per 1 point CGI-S increase, 95%CI: 1.18-1.44; post-mixed RR=1.35, 95%CI: 1.15-1.57) and hospitalisation for the mania/mixed episode (post-mania RR=1.22, 95%CI: 1.09-1.37; post-mixed RR=1.71, 95%CI: 1.52-1.94). Among medications prescribed during hospital-associated manic/mixed episodes, lithium (post-mania RR=0.75, 95%CI: 0.62-0.91; post-mixed RR=0.72, 95%CI: 0.54-0.95), first-generation sedating antihistamines (post-mania: RR=0.74, 95%CI: 0.63-0.87) and other mood stabilisers (post-mania RR=0.82, 95%CI: 0.71-0.94, post-mixed RR=0.82, 95%CI: 0.72-0.94) were associated with longer transition time. Antipsychotics, antidepressants and benzodiazepines were not. Shorter transition time was associated with more depression-related hospital days (16% fewer days per month delay to depression, 95%CI: 4-25%, p=0.010). Interpretation It is important to monitor for depression soon after manic/mixed episodes. This depression may be predictable, and might be preventable with some medications prescribed during the manic/mixed episode.

Background: Personality change is a debilitating consequence of traumatic brain injury (TBI), yet its prevalence, characteristics, and treatment remain poorly understood. Methods: We completed a pre-registered (CRD42023440990) systematic review and meta-analysis searching four databases (MEDLINE, PsycINFO, EMBASE and CINAHL) for primary studies assessing personality change after TBI. We synthesised conceptualisation, prevalence, longitudinal outcome, lesion location and treatment. Prevalence was estimated using a random effect meta-analysis using the Paule-Mandel estimator, with subgroup, meta-regression and robustness analyses. Results: 101 studies were included in this review, seventeen of which were suitable for meta-analysis. Personality change was defined inconsistently although common symptoms involved the emergence or increase of affective, behavioural, and social disturbances, including irritability, depression, emotional instability, anger outbursts, social withdrawal, anxiety, impulsivity, restlessness, aberrant motor behaviours, and aggression. The prevalence of secondary personality disorder was estimated as 29.1% (CIs 22.5% - 36.2%) and prevalence of broad personality change was 68.1% (CIs 53.4% - 81.2%). Robustness analyses showed that the estimate for broad personality change should be treated with caution as it was unstable when adjusted for risk of bias and potential publication bias. Follow-up studies, although of varying quality, consistently showed personality change remained stable over long follow-up periods. The relationship between personality change and specific lesion locations in TBI remains unclear, likely due to the poor methodological quality of studies examining this association. Perhaps most concerning, there is limited evidence and very few systematic studies addressing treatment. Conclusion: Personality change is a common and persistent consequence of TBI. Varying definitions, and the lack of high-quality lesion mapping studies and systematic investigations into treatment highlights critical gaps in understanding and management.

Improving minority ethnic student retention is a global higher education priority. This mixed-methods study investigated how institutional belonging and socioeconomic status interact to shape dropout intentions among minority university students in the UK (N = 182). Quantitative results revealed that perceived course difficulty and lower subjective socioeconomic status were the strongest predictors of dropout intent. While the interaction between socioeconomic status and difficulty was non-significant, qualitative accounts showed distinct structural vulnerabilities. Financial strain restricted social integration, turning socioeconomic disparities into campus isolation. Conversely, representative curricula, diverse peer networks, and stable cultural in-groups (e.g., religious affiliations, living in the parental home) functioned as essential psychological buffers against academic exhaustion and alienation. Universities must shift from transactional models to sustained structural equity to protect vulnerable student groups.

Purpose: Suicide mortality is underestimated due to misclassification under undetermined and accidental deaths. This study examined national trends in suicide and related external causes of death in Portugal from 2002 to 2023, by sex and age group, assessing potential shifts suggesting masked suicide and quantifying the relationship between undetermined, suicide, and accident death rates through ratio indices. Methods: Using official mortality data from Portugal's Statistics Institute (INE) for 2002-2023, we calculated age-standardised (SDR) and age-specific death rates (ASDR) for suicide (X60-X84), undetermined intent deaths (Y10-Y34), and unintentional deaths (V01-X59), disaggregated by sex and four age groups (15-24, 25-44, 45-64, 65+). We estimated undetermined-to-suicide (UnD:Suic) and undetermined-to-accidents (UnD:Accs) rate ratios for SDRs and ASDRs. Trends were analysed using joinpoint regression (APC/AAPC) and structural breakpoint analysis (Chow test, BIC). Results: Suicide SDRs declined across the period for males (AAPC: -2.25%) and females (AAPC: -1.32%), with the sharpest reductions among males aged 25-44 (AAPC: -2.56%) and females aged 65+ (AAPC: -2.44%). Deaths of undetermined intent rose steeply from 2002 to 2005-2006 and declined thereafter. Unintentional deaths declined in most age groups, except females aged 65+ (AAPC: +1.41%). Both ratio series peaked around 2005-2009, declined progressively through the 2010s, and reached their lowest values in 2021-2022. Age-specific analyses revealed a significant and sustained increase in both ratios among females aged 45-64. Structural breakpoints clustered around 2004, 2013-2015, and 2019-2020. Conclusion: Suicide mortality declined in Portugal from 2002 to 2023, but divergent trends in undetermined and accidental deaths across sex and age subgroups highlight ongoing misclassification. Age- and sex-specific ratio analyses identify the population subgroups where misclassification is most concentrated, providing a foundation for future imputation-based estimates of probable suicide burden.

Accumulating evidence suggests alterations in neurocognitive, affective, interoceptive and autonomic processing in functional neurological disorder (FND), yet interventions targeting these processes remain underexplored. This study investigated the possible immediate and longer-term effects of a somatic yoga intervention on cognitive control, emotion regulation, state dissociation and affect, autonomic arousal, and interoceptive processing in FND. Twenty-three adults with FND completed six weeks of somatic yoga (N=12) or six weeks of a music-based relaxation control (N=11). At baseline, post-single session, and post-six weeks, participants completed laboratory measures of sustained attention, response inhibition, interoception, emotion regulation, and state dissociation and affect. Electrocardiography and galvanic skin conductance were recorded throughout. Linear mixed effects models assessed potential change on day one, immediately pre/post a single session, and from day 1 to the end of the six-week programme. After one session, stop signal reaction time, negative affect, and heartrate decreased in both groups ({Delta}=.69-.75). After one session and at six weeks, improved sustained attention, elevated positive affect, and reduced dissociation were seen in both groups, with a larger magnitude of change in yoga ({Delta}=.50-1.10). The yoga group exhibited fewer direction errors on the response inhibition task and shorter response times on the sustained attention task, with the opposite seen in the music group ({Delta}=.50-1.17). Both in the short- and longer-term, somatic yoga might lead to adaptive changes in attention and executive functioning, arousal, state affect and dissociation.

Background: Depression is clinically heterogeneous, and immune-metabolic disturbances may not map uniformly onto categorical diagnosis or symptom severity. In populations exposed to substantial structural adversity, it remains unclear whether inflammatory and metabolic biomarker differences reflect adversity exposure itself or cluster around specific depressive phenotypes. Methods: Data were drawn from the Sao Paulo Megacity Mental Health Survey, a population-based study in which 5,037 household residents underwent structured psychiatric interviews. Among 770 participants assessed as having clinically significant symptoms (SCID-I), individuals with chronic physical illnesses, hs-CRP >20 mg/L, or missing data were excluded, yielding an analytic sample of 653. Latent class analysis of 16 DSM-IV depressive symptoms was used to identify symptom-derived phenotypes. Multinomial logistic regression tested associations between latent classes and immune-metabolic biomarkers, including hs-CRP, lipid fractions, fasting glucose, and triglycerides, adjusting for age, sex, education, smoking, and BMI. Results: A four-class solution identified asymptomatic (44.56%), mild-moderate (19.14%), atypical-like (16.69%), and melancholic-like (19.60%) classes. The two highseverity classes diverged by neurovegetative features: atypical-like depression was characterised by weight gain, hypersomnia, and psychomotor retardation, whereas melancholic-like depression was characterised by weight loss, insomnia, and psychomotor agitation. hs-CRP was highest in the atypical-like class and lowest in the melancholic-like class despite similar symptom severity. After BMI adjustment, elevated hs-CRP in the atypical-like class attenuated, whereas lower hs-CRP in the melancholic-like class persisted. Other metabolic markers did not robustly differentiate classes after adjustment. Conclusions: Immune-metabolic differences in depression do not simply follow symptom severity. In this Sao Paulo cohort, higher and lower hs-CRP profiles clustered around distinct latent depressive phenotypes, supporting biologically heterogeneous depressive presentations within a socially exposed urban population.

This qualitative study evaluated the Life Skills (HpV) training strategy at a public university in Colombia in 2024, analyzing its impact on students positive mental health and psychosocial competencies. The mixed-methods research employed semi-structured interviews with faculty and three student focus groups, using thematic analysis to categorize strengths, weaknesses, and perceived changes. Results highlighted curricular coherence, academic freedom, and participatory methodology as key aspects, fostering self-awareness, emotional management, and the building of support networks. Students reported improvements in well-being, stress management, and academic performance, though challenges such as initial resistance to emotional content and student diversity were identified. The conclusions underscore the value of experiential courses in university education, promoting horizontal relationships and safe spaces for collective reflection. Future studies are recommended to expand participant diversity and incorporate quantitative data triangulation to further explore the interventions effects.

Objective: To examine railway suicide trends and change points in Australia and across states/territories. Methods: We identified railway suicides that occurred in Australia between 2001 and 2023, using data from the National Coronial Information System. We performed negative binomial regression analysis to examine railway suicide trends and joinpoint regression analysis to identify potential change points at both national and state/territory levels. Results: Between 2001 and 2023, railway suicide in Australia declined by 54% (Incidence rate ratio [IRR] 0.98, 95% Confidence Interval [CI] 0.97 to 0.99). Substantial declines were observed in Victoria (-62%, IRR 0.97, 95% CI 0.96 to 0.99) and New South Wales (-67%, IRR 0.97, 95% CI 0.96 to 0.99), and, to a lesser extent, in Queensland (-25%, IRR 0.97, 95% CI 0.95 to 0.99). Nationally, one change point was identified. Between 2017 and 2023, the annual percent change was -8.8% (95% CI -24.5 to -3.3). In Victoria, railway suicide rates decreased annually by 13.6% between 2018 and 2023 (95% CI -38.5 to -4.3). In Western Australia, railway suicide rates increased annually by 10.3% between 2002 and 2010 (95% CI 1.5 to 58.8) and decreased annually by 5.4% between 2010 and 2023 (95% CI -19.8 to -1.8). No change point was identified for other states/territories. Conclusion: Australian railway suicides have declined substantially, with this trend largely driven by reductions in Victoria and New South Wales. These findings demonstrate that railway suicide is preventable through multisectoral initiatives and suggest that interventions should be continued to reduce railway suicide.

Background. Despite growing evidence that lifestyle interventions reduce depressive symptoms, the psychological mechanisms underlying these effects remain poorly understood. This study examined whether mindfulness and rumination mediate the antidepressant effects of heated yoga (HY), a multicomponent intervention combining physical activity, attentional training, and thermoregulatory stress. Methods. This prespecified secondary mediation analysis builds on a randomized controlled trial in which 80 adults with moderate-to-severe depression (IDS-CR > 23) were randomized to 8 weeks of twice-weekly HY or waitlist control. Subsamples with complete mediator data contributed to rumination (n = 56) and mindfulness (n = 60) models. Causal mediation analyses with 10,000 bootstrap resamples estimated indirect effects on Week 8 depression severity via Week 4 mediator changes. Sensitivity analyses assessed unmeasured confounding required to nullify observed effects. ClinicalTrials.gov: NCT02607514. Results. As previously reported, HY produced significantly greater IDS-CR reductions at Week 8 versus controls (p < .001). HY was associated with decreased rumination (p < .01) and increased mindfulness (p < .001) at Week 4. Increased mindfulness was statistically consistent with mediating depressive symptom reductions (ACME: -2.71, 95% CI [-5.42, -0.99]), whereas decreased rumination was not (ACME: -2.41, 95% CI [-6.28, 0.43]). Results were resilient to sensitivity analyses. Conclusion. In this RCT of a behavioral lifestyle intervention, mindfulness but not rumination emerged as a statistically significant mediator of depressive symptom reductions, identifying mindfulness as a key candidate mechanism through which multicomponent lifestyle interventions may exert antidepressant effects and suggesting a target for optimizing behavioral treatments for depression.

Moderate-to-severe traumatic brain injury (msTBI) is recognized as a chronic and evolving neurological condition characterized by progressive structural brain changes and persistent cognitive impairment. While prior studies have demonstrated widespread atrophy following msTBI, less is known regarding the longitudinal trajectory of gray matter (GM) changes during recovery and post-rehabilitation. The current study used longitudinal voxel-based morphometry (VBM) to characterize GM volume changes over a period of 9 months, in individuals with msTBI relative to healthy controls (HC). Associations between regional GM volume and neuropsychological functioning were examined. Twenty-eight participants (14 msTBI, 14 HC) completed MRI and neuropsychological assessments across three timepoints spanning outpatient rehabilitation and follow-up. Longitudinal VBM analyses revealed significant group and time interactions within subcortical and limbic regions. Relative to HC, individuals with msTBI showed lower GM volume in these regions at baseline, with trajectories that converged toward HC values (right hippocampus) or increased relative to HC over the rehabilitation period (bilateral pulvinar), whereas the right amygdala and inferior cerebellar vermis remained persistently reduced. Significant longitudinal improvements in memory and psychomotor speed during the rehabilitation period were demonstrated in msTBI. Greater (preserved) GM volume within the right hippocampus, thalamus, and bilateral pulvinar was associated with better performance across measures of verbal memory, processing speed, executive functioning, and cognitive flexibility. These findings suggest that msTBI is associated with dynamic structural brain changes involving subcortical, limbic, and cerebellar networks, and that the rehabilitation period was accompanied by relative volumetric stabilization in these regions and by meaningful cognitive improvement.

Background: Returnee migrants in Nigeria often face significant psychosocial and economic challenges during reintegration, necessitating resilience to adapt and recover. This study examined factors influencing resilience among returnee migrants in Nigeria. Methodology: A mixed methods design was employed, involving 1316 returnees selected through multistage sampling across Nigeria six geopolitical zones. Quantitative data were collected using the Connor Davidson Resilience Scale and analyzed using SPSS version 28. Qualitative data was obtained through eight focus group discussions and analyzed thematically. Result: Social support from family and friends was inconsistent (70.8% reported occasional support), while community support was largely absent (85.9%). Financial insecurity was widespread (gt 90%). Male gender (AOR = 6.092, plt 0.001), ethnicity, and higher education were significant predictors of resilience. Qualitative findings highlighted the role of family support, faith, adaptive coping, and skill acquisition in strengthening resilience. Conclusion: Resilience among returnee migrants in Nigeria is limited by weak structural and economic support, despite moderate personal coping capacity. Strengthening economic opportunities, community integration, and access to mental health services is essential for sustainable reintegration. Keywords: Returnee migrants, resilience, Reintegration, and psychosocial factors.

Introduction Auto-Induced Cognitive Trance (AICT) is a non-ordinary state of consciousness (NOSC) that can be accessed by will alone once a standardised self-induction procedure has been learnt. The first research publication on AICT dates back only ten years, meaning that research on this phenomenon is still in its infancy. Previous reports concerning the phenomenology and neurophysiology of AICT revealed similarities with more extensively described NOSCs, as well as unusual features, raising questions about the potential benefits of AICT practice for well-being. Objective This study aimed to gather quantitative descriptive data on features associated with well-being in a large comparative sample of AICT practitioners and non-practitioners. Method This research followed a web-based survey study design which enquired AICT-trained and yet-to-be trained participants to self-report through validated standardised questionnaires on vitality, self-esteem, mental well-being, trait anxiety, life satisfaction, happiness, positive and negative affect, nature-relatedness and connectedness. Data on NOSCs practices, life history events that could have led to spontaneous NOSCs, and demographic data were collected for further inclusion as control variables in statistical models. Results The online questionnaire yielded 607 valid responses, (171 yet-to-be trained participants and 436 AICT-trained participants). AICT practice was found to be associated with increased self-esteem (RSE), overall connectedness (WCS) as well as all subdimensions of connectedness (WCS Self, WCS Others, WCS World). AICT practice Duration exhibited significant effects on global connectedness and all subdimensions of connectedness, self-esteem, trait anxiety (STAIT-5), and positive affect (PANAS+). Conclusions AICT seems to benefit to practitioners well-being shortly after training through increases in self-esteem and in the sense of connectedness. Prolonged AICT practice is associated with added decreased trait anxiety and increased positive affect. Further research is needed to confirm these findings with a sample including AICT-uninterested participants, and to clarify the underlying mechanisms of AICT.

Major depressive disorder (MDD) is a leading cause of disability worldwide with risk of onset and recurrence linked to depressive ruminative thought patterns. Mindfulness-based cognitive therapy (MBCT) is an evidence-based treatment for depression that targets the ability to recognise, decenter, and disengage from ruminative thought patterns. Elucidating how MBCT impacts hierarchical brain organisation may be key to understanding the processes by which MBCT can modulate ruminative tendencies. In a randomised controlled functional magnetic resonance imaging (fMRI) trial on individuals with MDD (N=80) before and after MBCT in addition to treatment as usual (TAU), we investigated changes in hierarchical brain organisation during resting-state and rumination. We built whole-brain models to obtain generative connectivity (GEC) matrices per patient and quantified brain hierarchy by measuring the global directedness and regional trophic levels in each GEC, in which greater directedness reflects more directional information flow and less recurrence. Global directedness in MBCT+TAU compared to TAU increased during rumination, with no changes during resting-state. Furthermore, increased regional breadth of hierarchy during rumination was related to improvements in clinical and behavioural outcomes following MBCT+TAU. Increased brain hierarchy during rumination following mindfulness training may be consistent with a shift away from self-reinforcing negative mental loops towards more differentiated and less coupled cognitive and bodily cycles, supporting MBCT's ability to interrupt ruminative processes. Hierarchical brain dynamics may hold promise as a treatment-sensitive marker and a potential mechanism of therapeutic change in MBCT for depression.

Background Oral care is a critical nursing intervention for mechanically ventilated patients in intensive care units (ICUs) and plays an important role in preventing ventilator-associated complications. However, variability in nurses' competency in oral care remains a concern, particularly in resource-limited settings. Objective To assess ICU nurses' competency in providing oral care to mechanically ventilated patients and determine factors associated with competency at Tenwek Hospital, Kenya. Methods An analytical cross-sectional study was conducted among ICU nurses at Tenwek Hospital. A total of 38 nurses were invited, and 35 participated, yielding a response rate of 92.1%. Data were collected using a structured questionnaire and an observational competency checklist. Descriptive statistics and inferential analysis, including chi-square tests and binary logistic regression, were performed using SPSS version 30. Statistical significance was set at p<0.05. Results ICU nurses demonstrated generally high competency in key oral care practices, including use of personal protective equipment (100%), suctioning before and after oral care (91.4%), and oral assessment (80.0%). However, gaps were identified in documentation of oral care (62.9%) and adherence to standardized protocols (65.7%). Formal oral care training was significantly associated with competency (OR=5.63, 95% CI: 1.78-17.81, p=0.002), as were professional qualification (p=0.030) and ICU experience (p=0.021). In multivariable analysis, oral care training (OR=3.01, p=0.006), ICU experience (OR=2.85, p=0.015), and availability of guidelines (OR=2.17, p=0.047) were independent predictors of competency. Conclusion ICU nurses at Tenwek Hospital demonstrate satisfactory competency in oral care for mechanically ventilated patients, although gaps remain in documentation and protocol adherence. Strengthening training, guideline availability, and institutional support systems is essential to improve consistency and quality of oral care practice.
