Association between severe premenstrual disorders and change of romantic relationship: A prospective cohort of 15,606 women in Sweden

BACKGROUND

Premenstrual disorders (PMDs) affect women's quality of life, yet the impact on romantic relationships remains unclear. This study aimed to examine the association between severe PMDs and relationship disruption and initiation.

METHODS

We conducted a prospective cohort study of 15,606 women during 2009-2021 in Sweden. PMDs were assessed with the modified Premenstrual Symptom Screening Tool at baseline (one-time retrospective self-report), while relationship status was obtained from national population registers during follow-up. Poisson regression was employed to assess the risk of relationship change.

RESULTS

At baseline (mean age 33.5 years), 1666 (10.6 %) women met the criteria for severe PMDs. All women were followed for 9.1 years on average for any change of relationship status. Among married/cohabiting women, PMDs were positively associated with relationship disruption (Incidence risk ratio, IRR =1.21, 95 % CI: 1.01-1.43, p = 0.03). A more pronounced association was suggested for premenstrual dysphoric disorder (IRR = 1.22, 95 % CI: 1.01-1.45, p = 0.03) than severe premenstrual syndrome (IRR = 1.01, 95 % CI: 0.43-1.96, p = 0.98) and among women without depression/anxiety (IRR = 1.21, 95 % CI: 1.00-1.47, p < 0.05) than among those with (IRR = 0.99, 95 % CI: 0.61-1.54 p = 0.96) and IRR = 1.01, 95 % CI: 0.57-1.72, p = 0.97). Among single women, a null association was found between PMDs and relationship initiation (IRR = 1.05, 95 % CI: 0.95-1.15, p = 0.32).

LIMITATIONS

PMDs were not assessed using prospective symptom charting.

CONCLUSIONS

Married/cohabiting women with probable severe PMDs have an increased risk of relationship disruption. PMDs were not associated with relationship initiation in single women. Healthcare professionals should recognize relationship challenges in women with severe PMDs, and they may require support to maintain healthy relationships.

Intergenerational Continuity of Childhood Adversity and Its Underlying Mechanisms Among Teen Mothers and Their Offspring

The present study investigates how parenting stress mediates the intergenerational continuity of childhood adversity in teenage mothers. Childhood adversity experiences of caregivers significantly affect their offspring's exposure to childhood adversity. However, little is known about the mechanisms linking childhood adversity across generations. The study measures how parental distress and parent-child dysfunctional interaction mediate the association between teen mothers' childhood adversity and their offspring's adversity, measuring when the offspring reached 11.5 years of age. The results revealed that parental distress, but not parent-child dysfunctional interaction, mediated the association between teen mothers' child abuse and their offspring's household dysfunction. This suggests that parental distress may be a crucial intervention target to prevent the intergenerational continuity of childhood adversity. The findings imply that efforts to prevent the intergenerational continuity of childhood adversity may be more successful if the public and professionals have a broader understanding of the associations between early adversity and parenting contexts. In conclusion, the study shed light on the potential mechanisms underlying the intergenerational continuity of childhood adversity and highlights the importance of targeting parenting stress, specifically parental distress, as an intervention strategy to prevent the perpetuation of childhood adversity across generations.

Coming of age in war: Early life adversity, age at menarche, and mental health

Armed conflict and forced migration (ACFM) represent a set of extreme environments that are increasingly common for children and adolescents to experience. Adolescence may constitute a sensitive period (puberty and psychoneurological maturation) through which ACFM adversity leaves a lasting mark. Adolescence has become a focal point for analysis and intervention as it relates to the effects of early life adversity on puberty, linear growth, and mental health. Research in public health and psychological science suggests early life adversity (ELA) may accelerate puberty, heightening risks for mental health disorders. However, it is not well substantiated whether ACFM-derived adversities accelerate or delay relative pubertal timing. Secondly, ACFM provides salient context through which to probe the relationships between nutritional, psychosocial, and demographic changes and their respective impact on puberty and mental health. We conducted a narrative review which 1) examined constructions of early life adversity and their proposed influence on puberty 2) reviewed empirical findings (n = 29 studies, n = 36 samples) concerning effects of ACFM ELA on age at menarche and 3) discussed proposed relationships between early life adversity, puberty, and mental ill-health. Contrary to prior research, we found war-derived early life adversity was more consistently associated with pubertal delay than acceleration and may exert counterintuitive effects on mental health. We show that ELA cannot be operationalized in the same way across contexts and populations, especially in the presence of extreme forms of human stress and resilience. We further discuss the ethics of puberty research among conflict-affected youth.

Adult symptoms of ASD and ADHD in relation to alcohol use: Potential roles of transdiagnostic features

Attention Deficit Hyperactivity Disorder (ADHD) is the most common comorbidity in Autism Spectrum Disorder (ASD). ADHD is a risk factor for alcohol misuse whereas ASD is often regarded as protective; however, research on ASD and alcohol use has yielded conflicting findings, sometimes implicating the role of comorbid ADHD. The possibility that certain transdiagnostic features (i.e., characteristics associated with multiple disorders) may underlie relationships of both disorders to alcohol use in adults was examined in the present study. A nonclinical young adult sample of 248 alcohol users (117 men, 131 women) completed validated self-report measures of ASD and ADHD symptoms as well as the transdiagnostic features alexithymia, impulsivity, and negative moods. ASD and ADHD symptoms were normally distributed, suggesting that the respective disorders represent extreme, dysfunctional ends of population distributions of symptoms. Path analysis indicated that the significant positive association between ASD and ADHD symptom measures was fully mediated by alexithymia, impulsivity, and negative moods. Hierarchical regression and path analysis indicated that the positive relationship between ADHD symptoms and alcohol use severity was fully mediated by transdiagnostic features, particularly alexithymia and impulsivity, whereas the relationship between ASD and alcohol use severity was positively mediated by these features (especially alexithymia), with a highly significant and negative direct effect. Present findings may help reconcile previous conflicting evidence on the relationship of ASD to alcohol use, and the role of comorbid ADHD, by emphasizing the roles of alexithymia and impulsivity in both ASD and ADHD as transdiagnostic traits promoting excessive drinking.

Sleep disturbance as a poor prognostic predictor in patients with advanced non-small-cell lung cancer treated with immune checkpoint inhibitors: A prospective study

BACKGROUND

Sleep disturbances are highly prevalent in oncology and often exacerbate symptoms, leading to reduced quality of life, which in turn may further affect the tolerability and efficacy of oncological treatments. Sleep disturbance and cancer have an intimate and complicated relationship, and may be a negative predictor of cancer treatment. The present study aimed to characterize the relationship between sleep disturbance and immune checkpoint inhibitor (ICI) therapy in patients with advanced non-small cell lung cancer (NSCLC).

METHODS

Data from 171 patients with advanced NSCLC, who underwent ICI treatment between December 2020 and October 2022, were analysed in our prospective study. Sleep disturbances were evaluated according to the Pittsburgh Sleep Quality Index (PSQI), with a cut-off value of 5, to investigate the impact of sleep disturbance on the survival of patients with NSCLC and the efficacy of ICI treatment.

RESULTS

The median progression-free survival (PFS) was10.4 months (9 5% confidence interval [CI]:9.84-10.97). Univariate and multivariate analyses revealed that sleep disturbance and depressive symptom predicted worse prognosis with shortened PFS. Patients who experienced sleep disturbance exhibited a significant reduction in PFS (9.2 vs. 11.8 months; HR: 1.83 [9 5% CI 1.27-2.6 5]; p = 0.001), as did those with depressive states (HR 1.5 5 [9 5% CI 1.06-2.28]; p = 0.02 5). Additionally, patients with sleep disturbance and depressive symptoms exhibited significantly lower objective response rates and disease control rates.

CONCLUSION

Sleep disturbance could be a factor for prognosis in patients with advanced NSCLC undergoing first- or second-line treatment with ICIs, including shorter PFS and reduced efficacy.

Machine learning approach to investigate pregnancy and childbirth risk factors of sleep problems in early adolescence: Evidence from two cohort studies

BACKGROUND

This study aimed to predict early adolescent sleep problems using pregnancy and childbirth risk factors through machine learning algorithms, and to evaluate model performance internally and externally.

METHODS

Data from the China Jintan Child Cohort study (CJCC; n=848) for model development and the US Healthy Brain and Behavior Study (HBBS; n=454) for external validation were employed. Maternal pregnancy histories, obstetric data, and adolescent sleep problems were collected. Several machine learning techniques were employed, including least absolute shrinkage and selection operator, logistic regression, random forest, naïve bayes, extreme gradient boosting, decision tree, and neural network. The area under the receiver operating characteristic curve, sensitivity, specificity, accuracy, and root mean square of residuals were used to evaluate model performance.

RESULTS

Key predictors for CJCC adolescents' sleep problems include gestational age, birthweight, duration of delivery, and maternal happiness during pregnancy. In HBBS adolescents, the duration of postnatal depressive emotions was the primary perinatal predictor. The prediction models developed in the CJCC had good-to-excellent internal validation performance but poor performance in predicting the sleep problems in HBBS adolescents.

CONCLUSION

The identification of specific perinatal risk factors associated with adolescent sleep problems can inform targeted interventions during and after pregnancy to mitigate these risks. Health providers should consider integrating these predictive factors into routine pre- and postnatal assessments to identify at-risk populations. The variability in model performance across different cohorts highlights the need for context-specific models and the cautious application of predictive analytics across diverse populations. Future research should focus on refining predictive models to account for such variations, potentially through the incorporation of additional socio-cultural factors and genetic markers. This study emphasizes the importance of personalized and culturally sensitive approaches in the prediction and management of adolescent sleep problems, leveraging advanced computational methods to enhance maternal and child health outcomes.

Higher inflammatory proteins predict future depressive symptom severity among adolescents with lower emotional clarity

BACKGROUND

A growing body of work has implicated inflammation in the pathogenesis of depression. As not all individuals with heightened levels of peripheral inflammation develop symptoms of depression, additional work is needed to identify other factors that catalyze the relationship between inflammation and depressive symptoms. Given that elevated levels of inflammatory activity can induce a variety of emotional changes, the present study examined whether emotional clarity, the trait-like ability to identify, discern, and express one's emotions, influences the strength of the association between inflammatory signaling and concurrent and prospective symptoms of depression.

METHODS

Community adolescents (N = 225, Mage = 16.63 years), drawn from a larger longitudinal project investigating sex and racial differences in depression onset, provided blood samples to determine peripheral levels of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and C-reactive protein (CRP) at a baseline visit, along with self-report measures of emotional clarity and depressive symptom severity. Depressive symptom severity was assessed again at a follow-up visit approximately 5-months after baseline.

RESULTS

Hierarchical multiple regressions detected a significant interaction between inflammatory markers and emotional clarity on future depression severity, controlling for baseline depressive symptoms. Specifically, among adolescents with low levels of emotional clarity, higher levels of IL-6, CRP, and inflammatory composite scores were significantly associated with greater future depression severity.

CONCLUSIONS

These results indicate that low emotional clarity and high inflammatory signaling may jointly confer risk for prospective depressive symptom severity among adolescents. Therapeutic interventions that improve emotional clarity may reduce risk of depressive symptoms among adolescents with low-grade peripheral inflammation.

Unveiling the neurolipidome of obsessive-compulsive disorder: A scoping review navigating future diagnostic and therapeutic applications

Obsessive-Compulsive Disorder (OCD) poses a multifaceted challenge in psychiatry, with various subtypes and severities greatly impacting well-being. Recent scientific attention has turned towards lipid metabolism, particularly the neurolipidome, in response to clinical demands for cost-effective diagnostics and therapies. This scoping review integrates recent animal, translational, and clinical studies to explore impaired neurolipid metabolism mechanisms in OCD's pathogenesis, aiming to enhance future diagnostics and therapeutics. Five key neurolipids - endocannabinoids, lipid peroxidation, phospholipids, cholesterol, and fatty acids - were identified as relevant. While the endocannabinoid system shows promise in animal models, its clinical application remains limited. Conversely, lipid peroxidation and disruptions in phospholipid metabolism exhibit significant impacts on OCD's pathophysiology based on robust clinical data. However, the role of cholesterol and fatty acids remains inconclusive. The review emphasises the importance of translational research in linking preclinical findings to real-world applications, highlighting the potential of the neurolipidome as a potential biomarker for OCD detection and monitoring. Further research is essential for advancing OCD understanding and treatment modalities.

Women with depression in pregnancy or a history of depression have decreased quality of mentalization in the speech to their infants

BACKGROUND

Our study aims to understand whether depression, either in pregnancy or lifetime, affects cognitive biases (comprising the attentional focus and affective state) and mentalizing features (ability to understand children's internal mental states, thereby detecting and comprehending their behavior and intention), in maternal speech during mother-infant interaction in the first postnatal year.

METHODS

We recruited 115 pregnant women (44 healthy, 46 with major depressive disorder [MDD] in pregnancy, and 25 with a history of MDD but healthy pregnancy) at 25 weeks' gestation. Three-minute videos were recorded at 8 weeks and 12 months postnatally for each dyad. Maternal speech was transcribed verbatim and coded for cognitive biases and mentalizing comments using the Parental Cognitive Attributions and Mentalization Scale (PCAMs).

RESULTS

Women suffering from antenatal depression showed a decreased proportion of mentalizing comments compared with healthy women, at both 8 weeks (0.03 ± 0.01 vs. 0.07 ± 0.01, P = 0.002) and 12 months (0.02 ± 0.01 vs. 0.04 ± 0.01, P = 0.043). Moreover, compared with healthy women, both those with antenatal depression and those with a history of depression showed decreased positive affection in speech (0.13 ± 0.01 vs. 0.07 ± 0.01 and 0.08 ± 0.02, respectively P = 0.003 and P = 0.043), and made significantly fewer comments focused on their infants' experience at 8 weeks (0.67 ± 0.03 vs. 0.53 ± 0.04 and 0.49 ± 0.05, respectively P = 0.015 and P = 0.005). In linear regression models women's socioeconomic difficulties and anxiety in pregnancy contribute to these associations, while postnatal depression did not.

CONCLUSIONS

Both antenatal depression and a lifetime history of depression are associated with a decreased quality of women's speech to their infants, as shown by less focus on their infant's experience, decreased positive affection, and less able to mentalize. Examining maternal speech to their infants in the early postnatal months may be particularly relevant to identify women who could benefit from strategies addressing these aspects of the interactive behavior and thus improve infant outcome in the context of depression.

The epigenetic mechanism of metabolic risk in bipolar disorder

Bipolar disorder (BD) is a complex and severe mental illness that causes significant suffering to patients. In addition to the burden of depressive and manic symptoms, patients with BD are at an increased risk for metabolic syndrome (MetS). MetS includes factors associated with an increased risk of atherosclerotic cardiovascular disease (CVD) and type 2 diabetes mellitus (T2DM), which may increase the mortality rate of patients with BD. Several studies have suggested a link between BD and MetS, which may be explained at an epigenetic level. We have focused on epigenetic mechanisms to review the causes of metabolic risk in BD.

Sex differences in prolactin levels and clinical outcomes in patients with a first psychotic episode

AIM

To analyze the clinical, neurocognitive, and functional impact of prolactin levels according to sex in patients with a First Episode Psychosis (FEP).

METHODS

We measured prolactin levels in 221 non-affective FEP patients treated with antipsychotics (AP) and 224 healthy controls, at baseline and 2-year follow-up. We examined whether the relationships between clinical and functional variables were mediated by prolactin, controlling for antipsychotic use, according to sex.

RESULTS

Prolactin levels were higher in patients when compared to controls at both time points. Baseline factors associated with prolactin were chlorpromazine equivalents, attention, and executive functioning. In the FEP group, prolactin levels were associated with functioning and diminished expression in males, and with working memory in females. Prolactin levels (p=0.0134) played a role as a mediator between negative symptomatology (p=0.086) and functional outcome (p=0.008) only in FEP male patients at baseline.

CONCLUSIONS

Prolactin plays a role in the functionality and clinical symptomatology of FEP patients. Our results suggest that pharmacological counselling in patients with hyperprolactinemia at baseline and negative symptomatology might improve their functional and clinical outcomes.

A systematic review and meta-ethnography of client and therapist perspectives of the therapeutic alliance in the context of psychotherapy and suicidal experiences

This review aimed to develop a conceptual model of the therapeutic alliance in the context of psychotherapy and suicidal experiences from therapist and client perspectives. The protocol was pre-registered on PROSPERO (CRD42021268273). MEDLINE, PsycINFO, Web of Science, Embase and CINAHL were systematically searched from database inception to April 2024. Eligible studies were peer-reviewed, qualitative, and included client and/or therapist's perspectives of the therapeutic alliance in the context of psychotherapy and suicidal experiences. Studies were critically appraised and analysed using a meta-ethnography approach involving a reciprocal translation of studies and line of argument synthesis. Thirty-seven papers were included, generating two overarching themes; 'Working on the edge' and 'Being ready, willing, and able to build an alliance in the context of suicidal experiences'. Therapeutic alliance in the context of suicidal experiences is unique, fluid, potentially lifesaving, and influenced by multiple inter-connected internal and external processes and systems. Clinical implications emphasise the need to improve training, supervision, and support for therapists to equip them with the additional skills required in navigating the intricacies of the therapeutic alliance with clients who have suicidal experiences. Flexibly interweaving risk assessment into therapeutic conversation was beneficial to the alliance with suicidal clients and enhanced their safety.

Differential inflammatory profiles in carriers of reciprocal 22q11.2 copy number variants

BACKGROUND

Genetic copy number variants (CNVs; i.e., a deletion or duplication) at the 22q11.2 locus confer increased risk of neuropsychiatric disorders and immune dysfunction. Inflammatory profiles of 22q11.2 CNV carriers can shed light on gene-immune relationships that may be related to neuropsychiatric symptoms. However, little is known about inflammation and its relationship to clinical phenotypes in 22q11.2 CNV carriers. Here, we investigate differences in peripheral inflammatory markers in 22q11.2 CNV carriers and explore their relationship with psychosis risk symptoms and sleep disturbance.

METHODS

Blood samples and clinical assessments were collected from 22q11.2 deletion (22qDel) carriers (n=45), 22q11.2 duplication (22qDup) carriers (n=29), and typically developing (TD) control participants (n=92). Blood plasma levels of pro-inflammatory cytokines, including interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ), and anti-inflammatory cytokine interleukin-10 (IL-10) were measured using a MesoScale Discovery multiplex immunoassay. Plasma levels of C-reactive protein (CRP) were measured using Enzyme-linked Immunosorbent Assay (ELISA). Linear mixed effects models controlling for age, sex, and body mass index were used to: a) examine group differences in inflammatory markers between 22qDel, 22qDup, and TD controls, b) test differences in inflammatory markers between 22qDel carriers with psychosis risk symptoms (22qDelPS+) and those without (22qDelPS-), and c) conduct an exploratory analysis testing the effect of sleep disturbance on inflammation in 22qDel and 22qDup carriers. A false discovery rate correction was used to correct for multiple comparisons.

RESULTS

22qDup carriers exhibited significantly elevated levels of IL-8 relative to TD controls (q<0.001) and marginally elevated IL-8 levels relative to 22qDel carriers (q=0.08). There were no other significant differences in inflammatory markers between the three groups (q>0.13). 22qDelPS+ exhibited increased levels of IL-8 relative to both 22qDelPS- (q=0.02) and TD controls (p=0.002). There were no relationships between sleep and inflammatory markers that survived FDR correction (q>0.14).

CONCLUSION

Our results suggest that CNVs at the 22q11.2 locus may have differential effects on inflammatory processes related to IL-8, a key mediator of inflammation produced by macrophages and microglia. Further, these IL-8-mediated inflammatory processes may be related to psychosis risk symptoms in 22qDel carriers. Additional research is required to understand the mechanisms contributing to these differential levels of IL-8 between 22q11.2 CNV carriers and IL-8's association with psychosis risk.

Diet quality and associations with lactate and metabolic syndrome in bipolar disorder

BACKGROUND

Nutrition is largely affected in bipolar disorder (BD), however, there is a lack of understanding on the relationship between dietary categories, BD, and the prevalence of metabolic syndrome. The objective of this study is to examine dietary trends in BD and it is hypothesized that diets with increased consumption of seafood and high-fiber carbohydrates will be correlated to improved patient outcomes, and a lower frequency of metabolic syndrome.

METHODS

This retrospective cohort study includes two French cohorts. The primary cohort, FACE-BD, includes 268 stable BD patients. The second cohort, I-GIVE, includes healthy controls, both stable and acute BD and schizophrenia patients. Four dietary categories were assessed: meat, seafood, low-fiber and high-fiber carbohydrates. Dietary data from two food frequency questionnaires were normalized using min-max scaling and assessed using various statistical analyses.

RESULTS

In our primary cohort, the increased high-fiber carbohydrate consumption was correlated to lower prevalence of metabolic syndrome and improved mood. Low-fiber carbohydrate consumption is associated with higher BMI, while higher seafood consumption was correlated to improved mood and delayed age of onset. Results were not replicated in our secondary cohort.

LIMITATIONS

Our populations were small and two different dietary questionnaires were used; thus, results were used to examine similarities in trends.

CONCLUSIONS

Overall, various dietary trends were associated with metabolic syndrome, BMI, lactate, mood and age of onset. Improving our understanding of nutrition in BD can provide mechanistic insight, clinically relevant nutritional guidelines for precision medicine and ultimately improve the quality of lives for those with BD.

A parallel-arm, randomized trial of Behavioral Activation Therapy for anhedonia versus mindfulness-based cognitive therapy for adults with anhedonia

BACKGROUND

Anhedonia, deficits in motivation and pleasure, is a transdiagnostic symptom of psychopathology and negative prognostic marker.

METHODS

In this randomized, parallel-arm clinical trial, a novel intervention, Behavioral Activation Treatment for Anhedonia (BATA), was compared to an individually administered Mindfulness-Based Cognitive Therapy (MBCT) in a transdiagnostic cohort of adults with clinically significant anhedonia (ClinicalTrials.gov Identifiers NCT02874534 and NCT04036136). Participants received 8-15 individual psychotherapy sessions, once weekly, with either BATA (n = 61) or MBCT (n = 55) and completed repeated self-report assessment of anhedonia and other internalizing symptoms.

RESULTS

Indicators of treatment feasibility were similar across conditions, though MBCT showed a trend towards greater attrition rates than BATA, with an adjusted odd's ratio of 2.04 [0.88, 4.73]. Treatment effects on the primary clinical endpoint of anhedonia symptoms did not significantly differ, with a 14-week estimated difference on the Snaith Hamilton Pleasure Scale (SHAPS) of -0.20 [-2.25, 1.84] points in BATA compared to MBCT (z = 0.19, p = 0.845, d = 0.05). The expected 14-week change in SHAPS scores across conditions was -7.18 [-8.22, -6.15] points (z = 13.6, p < 0.001, d = 1.69). There were no significant differences in the proportion of participants demonstrating reliable and clinically significant improvements in SHAPS scores, or in the magnitude of internalizing symptom reductions.

LIMITATIONS

Limitations included a modest sample size, lack of longer-term follow up data, and non-preregistered analytic plan.

DISCUSSION

There was no evidence to support superior clinical efficacy of BATA over MBCT in a transdiagnostic cohort of adults with elevated anhedonia. Both interventions reduced anhedonia symptoms to a comparable magnitude of other existing treatments.

Alcohol consumption questionnaire: Scale development in a sample of Mexican American young adults and association with ADH7

BACKGROUND

To understand why some individuals who develop alcohol use disorders (AUD) first begin to drink heavily, a number of scales have been developed that index aspects of alcohol craving and restraint from drinking. We developed a new measure called the Alcohol Consumption Questionnaire (ACQ), based in part on items modified from scales used to index binge eating, because there are data to suggest that binge eating and binge drinking may share common antecedents. We present an initial validity study using data from a sample of Mexican Americans.

METHODS

Data were from 699 Mexican American young adults in San Diego County, CA. A subsample (n = 60) had short-term test-retest data. Factor analysis and reliability assessment guided item reduction. Item response theory (IRT) analyses quantified item severity and identified questions with differential item functioning (DIF). Logistic regression assessed associations of mean scale scores with AUD, adjusting for key demographics, alcohol expectancies and subjective response to alcohol. We also examined associations with a protective genetic variant downstream from the alcohol dehydrogenase 7 (ADH7) gene.

RESULTS

The scale was reduced from 20 to 14 questions, which can be summarized by a single overall score (Cronbach's alpha = 0.896) or by two sub-scores (Consumption: 12 items, Cronbach's alpha = 0.896; Enjoyment: 2 items, Cronbach's alpha = 0.780). Test-retest reliability was very high (0.80-0.98) in this sample. The overall ACQ score and each subdomain score were strongly associated with AUD (ORs = 5.95 mild; 11.41 moderate; 48.56 severe) and family history of AUD. Respondents with the protective genetic variant had significantly lower overall ACQ scores (p < 0.001).

CONCLUSION

The ACQ is a novel measure of alcohol consumption with strong relationships with both the AUD phenotype and ADH7 gene variants in a sample of Mexican American young adults.

Bidirectional Relations Among Maternal Positive Emotion, Infant Positive Emotionality, and Infant Physiological Regulation Across the First 18 Months of Life

Respiratory sinus arrhythmia (RSA), a marker of self-regulation, has been linked to developmental outcomes in young children. Although positive emotions may have the potential to facilitate physiological self-regulation, and enhanced self-regulation could underlie the development of positive emotions in early childhood, the relation between positive emotions and physiological self-regulation in infancy has been relatively overlooked. The current study examined the bidirectional associations among maternal positive emotion, infant positive emotionality, and infant resting RSA across the first 18 months of life. We used data from the Longitudinal Attention and Temperament Study (LanTs; N = 309 in the current analysis) to test the within- and between-person relations of study variables over time using a random-intercepts cross-lagged panel model. We found that infants with higher overall levels of positive emotionality also displayed greater resting RSA, and their mothers exhibited higher levels of positive emotion. However, there were negative cross-lagged associations within-person; higher than average infant positive emotionality predicted lower levels of infant resting RSA at the subsequent timepoint during early infancy, whereas higher than average infant RSA subsequently predicted decreased levels of infant positive emotionality later in infancy. Results highlight the importance of considering transactional relations between positive emotion and physiological self-regulation in infancy.

A systematic review of interpersonal processes and their measurement within experience sampling studies of self-injurious thoughts and behaviours

Self-injurious thoughts and behaviours (SITBs) are a leading cause of death, and interpersonal processes (IPs) appear to play a role in SITBs. This systematic review synthesises the literature on IPs and SITBs in daily life and addresses four critical questions: (1) Which IPs have been assessed and how, (2) How are differences in IPs between individuals associated with SITBs?, (3) How are differences in IPs within individuals associated with SITBs? and (4) Do IPs relate differently to self-injurious thoughts than behaviours? Our review followed PRISMA guidelines and eligible literature was screened until 25 April 2024. We identified 58 Experience Sampling studies (32.76% daily-diary studies) of which most focused on IPs from major SITBs theories (e.g., thwarted belongingness) but largely used inconsistent operationalizations. Results from 39 studies investigating within-person associations were mixed. Based on 26 studies, whether differences in IPs between individuals relate to SITBs remains unclear. Three studies have investigated whether IPs relate to the transition from thoughts to behaviours, but temporal models are needed to draw firm conclusions. Studies investigating IPs and SITBs in daily life are largely inconclusive. Psychometrically validated measures are warranted, and future daily-life studies would benefit from drawing on ideation-to-action frameworks.

A prospective longitudinal investigation of the trajectory of obsessive-compulsive symptoms during adolescence

Obsessive-compulsive symptoms (OCS) increase with age during childhood and adolescence, and subthreshold OCS in childhood associate with a higher probability of obsessive-compulsive disorder (OCD) diagnosis in adulthood. Additionally, average age of onset for OCD is in adolescence, with the majority of OCD cases emerging by early adulthood. Despite these trends, the specific course of OCS development in adolescence is relatively unknown. To this end, the present prospective longitudinal study used latent growth mixture modeling and a diverse community sample of 3,335 high schoolers to identify and characterize growth trajectories of OCS across middle to late adolescence. Results identified three trajectories: High-but-Remitting, Moderate-but-Escalating, and Low-and-Stable. Results also indicated age, gender, anxiety sensitivity, and distress tolerance as significant predictors of trajectory group membership, such that younger age and being female predicted classification in the High-but Remitting group, greater anxiety sensitivity predicted classification in both the High-but-Remitting and Moderate-but Escalating groups, and greater distress tolerance predicted a lower likelihood of classification in the High-but-Remitting and Moderate-but-Escalating groups. Taken together, these trajectories have illustrated the temporal course and development of OCS across key developmental years. Moreover, the trajectories and their corresponding predictors may help identify adolescents who are particularly vulnerable to developing OCD.

Differential associations between SARS-CoV-2 infection, perceived burden of the pandemic and mental health in the German population-based cohort for digital health research

Understanding the potential adverse effects of the COVID-19-pandemic on mental health remains a challenge for public health. Differentiation between potential consequences of actual infection with SARS-CoV-2 and the subjective burden of the pandemic due to measures and restrictions to daily life still remains elusive. Therefore, we investigated the differential association between infection with SARS-Cov-2 and subjective burden of the pandemic in a study cohort of 7601 participants from the German population-based cohort for digital health research (DigiHero), who were recruited between March 4th and April 25th 2022. Data was collected using the online survey tool LimeSurvey® between March and October 2022 in consecutive surveys, which included questionnaires on infection status and symptoms following COVID-19 as well as retrospective assessment of the subjective burden of the pandemic. We observed an association of a past SARS-CoV-2 infection on deteriorated mental health related symptoms, whereas no association or interaction with burden of the pandemic occurred. The association was driven by participants with persistent symptoms 12 weeks after infection. On a symptom specific level, neuropsychiatric symptoms such as exhaustion and fatigue, concentration deficits and problems with memory function were the primary drivers of the association with small effect sizes between 0.048 and 0.062 ηp2.

Elevated stress-responsive biomarkers are associated with HIV acquisition in young women in rural South Africa

OBJECTIVE

Biological markers of stress have been associated with HIV progression and pathogenesis but not with HIV incidence. We sought to determine if elevated stress-responsive biomarkers would be associated with incident HIV among adolescent girls and young women (AGYW).

DESIGN

We conducted a case-cohort study within the HIV Prevention Trials Network (HPTN) 068 study among 949 AGYW in South Africa. Cases were AGYW who tested HIV-positive during the eight-year follow-up. Unmatched controls were randomly selected from the HIV-negative population at enrollment.

METHODS

Dried blood spots from cases and controls were tested from enrollment (2011-2012) for C-reactive protein (CRP), herpes simplex virus type-1 (HSV-1) antibody titers, and cytomegalovirus (CMV) antibody titers. Cox proportional hazards models estimated the association between each biomarker and time to incident HIV.

RESULTS

Compared to AGYW with the lowest CRP levels, those with medium and high CRP levels had a higher hazard ratio (HR) of incident HIV [HR: 1.45, 95% confidence interval (CI): 0.95, 2.21; HR: 1.50, 95% CI: 0.98, 2.30, respectively], although not statistically significant. The relative hazard of incident HIV was also higher among AGYW who were CMV seropositive vs. seronegative (low antibodies HR: 2.18, 95% CI: 1.2, 3.87; medium HR: 2.25, 95% CI: 1.28, 3.95; high HR: 1.78, 95% CI: 0.99, 3.21). Those with the highest HSV-1 antibody levels experienced an increased hazard of HIV compared to those who were HSV-1 seronegative (HR: 1.58, 95% CI: 1.03, 2.44).

CONCLUSIONS

Biological stress may increase AGYW's susceptibility to HIV acquisition through changes in immune function, viral infection, and increased biological vulnerability to disease.

Medial prefrontal cortex connectivity with the nucleus accumbens is related to HIV serostatus, perceptions of psychological stress, and monocyte expression of TNF-a

Post-menopausal persons living with HIV (PWH) report elevated levels of psychological stress and monocyte activation compared to persons living without HIV (PWOH). Resting state functional connectivity (rsFC) of mesolimbic brain regions underpinning stress and emotion regulation are susceptible to inflammatory insult. Although psychological stress is elevated, rsFC reduced, and CD16+ monocytes overexpressed in the brains of PWH, it is unclear whether the relationships amongst these variables differ compared to PWOH. An ethnically diverse sample of postmenopausal women, 24 PWH and 30 PWOH provided self-report mood surveys and provided peripheral blood specimens to quantify LPS-stimulated CD16+/- expression of TNF-α via flow cytometric analysis. An anatomical and resting state functional MRI scan were used to derive time-series metrics of connectivity between the medial prefrontal cortex (mPFC) and the nucleus accumbens (NAcc) as well as the amygdala. A positive association was observed between levels of perceived stress and CD16+/- TNF-α in both LPS-stimulated and unstimulated cells. PLWH showed lower connectivity between mPFC and NAcc. In turn, lower rsFC between these regions predicted greater psychological stress and proportion of CD16-, but not CD16+, cells expression of TNF-α. Neuroimmune effects of monocyte inflammation on the functional connectivity of mesolimbic regions critical for discrimination of uncertainty-safety and reward signals were observed in an ethnically diverse sample of postmenopausal women living with and without HIV. PWH showed lower mPFC-NAcc functional connectivity, which in turn was associated with greater perceived stress.

Validation of the efficacy of a personalized information-provision and exercise-coaching app on the quality of life of menopausal women

OBJECTIVES

Menopausal symptoms severely impact women's quality of life (QoL). Digital health interventions provide an accessible, personalized alternative for managing menopausal symptoms. In this study, we validated the Menopause Assistant Manager (MAMA®; Hudit, Seoul, S. Korea) app developed to provide personalized information, exercise coaching, and management of appointments and medications to menopausal women, and evaluated its efficacy on their QoL.

STUDY DESIGN

This nonrandomized interventional trial enrolled 48 peri- and postmenopausal women into experimental (MAMA) and control (Waitlist) groups (n = 24 each). Participants in the MAMA group used the app for 8 weeks, whereas the Waitlist group received no intervention. Both groups continued their usual treatments.

MAIN OUTCOME MEASURES

Clinical assessments at baseline and study completion included the World Health Organization Quality of Life Brief Version (WHOQOL-BREF), Menopause Rating Scale, Patient Health Questionnaire-9, Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-15 (PHQ-15), Menopause Emotional Symptom Questionnaire, and Subjective Memory Complaints Questionnaire.

RESULTS

Compared with the Waitlist group, the MAMA group showed postintervention improvements in WHOQOL-BREF physical health (F = 4.84, P = .03) and environmental (F = 5.01, P = .03) domains and GAD-7 (F = 5.53, P = .02) and PHQ-15 (F = 4.14, P = .048) scores. Changes in WHOQOL-BREF physical health scores negatively correlated with PHQ-15 scores (ρ = -0.53, P = .004).

CONCLUSION

By increasing treatment accessibility, the app improved physical and environmental QoL and reduced anxiety and somatic symptoms. App-based exercise coaching alleviated somatic symptoms, and the in-app psychological content reduced anxiety by normalizing menopausal symptoms, providing accurate information, decreasing uncertainty, and improving symptom perception.

Ecological validity of executive function tests in predicting driving performance

Almost all of our everyday activities depend on executive function (EF) skills. In line with the increasing attention to the ecological validation of neuropsychological assessment and intervention methods, this study aimed to explore the ecological validity of a relevant set of widely used EF tests, mostly from well-known paradigms of EF assessment, in predicting driving ability. Ninety-six healthy novice drivers (Mage = 26.2 years, SD = 8.4; 48 female) completed four stages of our data collection including psychological, EF, and driving assessments. For the psychological assessment, validated measures of sensation-seeking, risk-taking, personality traits, ADHD symptoms, depression, anxiety, and stress were administered. For the EF assessment, selected tests from the Delis-Kaplan Executive Function System (D-KEFS: Trail Making, Design Fluency, and Tower) and the Behavioral Assessment of the Dysexecutive Syndrome (BADS: Key Search, Zoo Map, and Modified Six Elements) along with a computerized Stroop test were administered. For the driving assessment, we used a simulated driving test comprising of 14 key dimensions of driving skills. Several correlations and multiple regression analyses were conducted. Significant correlations were found between all the EF measures and driving performance. Moreover, the EF measures predicted the driving ability over and above the effects of previous driving experience and the psychological variables. These results provide supporting evidence for the ecological validity of the EF tests in predicting driving performance. The incorporation of assessment and intervention targeting multiple domains of EF into driving rehabilitation and education programs could be a focus of future research.

Effectiveness of the Maudsley Model of Anorexia Nervosa Treatment for Adults: A systematic review

BACKGROUND

Maudsley Model of Anorexia nervosa (AN) Treatment for Adults (MANTRA) is recommended by NICE for the treatment of adults with AN. However, despite this fact, the approach remains relatively understudied. The aim of this study was to systematically update the research evidence regarding the use of the MANTRA in the treatment of Eating Disorders (ED).

METHOD

The databases used were Web of Science, Scopus, and PsycInfo, including studies up to 31 May 2023. PRISMA guidelines were followed, and Cochrane tools were used to assess the risk of bias. The search focused on identifying published articles that discussed the usefulness of MANTRA as a component of treatment for ED, following PICO criteria.

RESULTS

Nine studies spanning the period from 2011 to 2023 were included. Findings suggested that MANTRA was effective in improving body mass index (BMI), eating symptomatology and emotional state. There were generally no significant differences compared to other treatment conditions. Limitations to interpreting this systematic review include the methodological quality of included studies and the elevated risk of bias.

CONCLUSIONS

This review was the first to examine the effectiveness of MANTRA. The results indicate that MANTRA has shown effectiveness similar to other treatments for adults AN patients in addressing key clinical variables. It has been used in different populations (adolescents, males, inpatients) and formats (group, online) However, more research is needed to determine its effectiveness.

Association between the performance of executive function and the remission of depressive state after clinical treatment in patients with depression

BACKGROUND

Previous studies have reported that patients with depression have significant cognitive impairment. The aim of this study is to comprehensively evaluate the impairment of executive functions in patients with depression and whether the cognitive behavior performance of executive function is association with remission of depressive state after clinical treatment.

METHODS

We used cognitive-behavioral test to evaluate the performance of executive functions of 95 inpatients with depression before hospitalization and conducted two follow-up evaluations of their depression status on the 15th day of hospitalization and approximately 9 months after discharge.

RESULTS

The performance of executive function except the accuracy of inhibition control in patients with depression were significantly worse than that of healthy controls. Multivariate linear regression analysis found that the reaction time of working memory not only had a significant linear relationship with the baseline depression scores of patients with depression, but also had a significant linear relationship with the reduced depression scores after two follow-up visits.

LIMITATIONS

We only used cognitive-behavioral data as indicators to evaluate the cognitive performances of participants and only measured three components of executive function.

CONCLUSIONS

The reaction time of working memory was a stable and effective predictor of symptom relief in patients with depression after clinical treatment. These results provide initial evidence for working memory to predict the clinical prognosis of inpatients with depression prospectively, which could be further leveraged to improve intervention approaches and analyze the heterogeneity of depression.

The role of cortisol in development and treatment of PTSD among service members: A narrative review

Posttraumatic stress disorder (PTSD) is a pervasive issue within military populations, with approximately 29 % of post-9/11 service members experience PTSD at some point in their lifetime. One potentially important factor in PTSD development and treatment response is dysregulation of the stress response system stemming from exposure to multiple traumas and sustained operational stress associated with military training and deployment. In particular, the end-product of the hypothalamic-pituitary-adrenal (HPA) axis, cortisol, is of particular interest to researchers examining physiological stress response in the context of mental health. Research exploring cortisol has been ongoing for decades, both to further understand its pathways and mechanisms, and to develop potential novel PTSD treatments. This paper provides a narrative review of some of the published literature examining cortisol's role in PTSD as a potential factor in development, maintenance, and treatment augmentation, with emphasis on military populations. The results of this review highlight the importance of exploring alterations to the stress response system, and cortisol in particular, for the evaluation and treatment of PTSD in the military, the need for more comprehensive work towards understanding development of these alterations through military training and service, and its impact on long-term PTSD outcomes.

Facilitating and hindering factors in the treatment of persistent somatic symptoms in migrants: A scoping review

OBJECTIVE

To identify facilitating and hindering factors in the treatment of persistent somatic symptoms (PSS) in migrants in psychiatry and other health care settings in Western countries.

METHODS

A scoping literature review was conducted by searching PubMed and Embase, using combinations of search terms related to the treatment of PSS in migrants. Studies outside of the scope of current guidelines or limited to specific underlying diseases such as post-traumatic stress disorder (PTSD) or consequences of torture were excluded. Two independent reviewers verified that the studies met the inclusion criteria, assessed the quality of the studies, and identified and categorized facilitating and hindering treatment factors.

RESULTS

Of the 347 unique citations identified in the initial the search, 18 studies met the inclusion criteria. These studies showed a wide variety in study design, interventions used, measurement instruments, and study quality. Common treatment adaptations related to: (a) translation and interpretation, (b) adaptation to lower educational levels, (c) culture-sensitive therapists and materials, (d) gender roles, (e) removal of practical barriers, (f) supportive treatment, and (g) nonverbal therapy forms. The most commonly mentioned influencing factors of treatment success related to: (a) body and experience-oriented treatment elements, (b) translation and communication, (c) cultural sensitivity, (d) group interaction, and (e) caring for one's own health.

CONCLUSION

This review provides an overview of available research on treatment adaptations for PSS in migratory background patients. Potential facilitating and hindering factors for treatment success that may be useful for healthcare providers treating PSS in patients with a migratory background were identified.

The impact of genetic variations in the serotonergic system on symptom severity and clinical outcome in functional neurological disorders

OBJECTIVE

We studied gene-environment, as well as gene-gene interaction to elucidate their effects on symptom severity and predict clinical outcomes in functional neurological disorders (FND).

METHODS

Eighty-five patients with mixed FND were genotyped for ten single-nucleotide polymorphisms (SNP) from seven different stress-related genes. We tested cross-sectionally the association between genotype and the symptomatology of FND (symptom severity assessed with the examiner-based clinical global impression score [CGI] and age of onset). Clinical outcome was assessed in 52 patients who participated in a follow-up clinical visit after eight months (following their individual therapies as usual). We tested longitudinally the association between genotype and clinical outcome in FND. We examined the contribution of each SNP and their interaction between them to FND symptomatology and outcome.

RESULTS

We identified a nominal association between tryptophan hydroxylase 1 (TPH1) rs1800532 and symptom severity (CGI1) in FND under a codominant model (T/T: ßT/T = 2.31, seT/T = 0.57; G/T: ßG/T = -0.18, seG/T = 0.29, P = 0.035), with minor allele (T) carriers presenting more severe symptoms. An association was identified between TPH1 and clinical outcome, suggesting that major allele (G) carriers were more likely to have an improved outcome under a codominant model (G/T: ORG/T = 0.18, CIG/T = [0.02-1.34]; T/T: ORT/T = 2.08, CIT/T = [0.30-14.53], P = 0.041). Our analyses suggested a significant gene-gene interaction for TPH2 (rs4570625) and OXTR (rs2254298) on symptom severity, and a significant gene-gene interaction for TPH1, TPH2 and BDNF (rs1491850) on clinical outcome.

CONCLUSION

FND might arise from a complex interplay between individual predisposing risk genes involved in the serotonergic pathway and their gene-gene interactions.

MEG Microstates: An Investigation of Underlying Brain Sources and Potential Neurophysiological Processes

Microstates are transient scalp configurations of brain activity measured by electroencephalography (EEG). The application of microstate analysis in magnetoencephalography (MEG) data remains challenging. In one MEG dataset (N = 113), we aimed to identify MEG microstates at rest, explore their brain sources, and relate them to changes in brain activity during open-eyes (ROE) or closed-eyes resting state (RCE) and an auditory Mismatch Negativity (MMN) task. In another dataset of simultaneously recorded EEG-MEG data (N = 21), we investigated the association between MEG and EEG microstates. Six MEG microstates (mMS) provided the best clustering of resting-state activity, each linked to different brain sources: mMS 1-2: left/right occipito-parietal; mMS 3: fronto-temporal; mMS 4: centro-medial; mMS 5-6: left/right fronto-parietal. Increases in occipital alpha power in RCE relative to ROE correlated with greater mMS 1-2 time coverage (τbs < 0.20, ps > .002), while the lateralization of deviance detection in MMN was associated with mMS 5-6 time coverage (τbs < 0.16, ps > .012). No temporal correlation was found between EEG and MEG microstates (ps > .05), despite some overlap in brain sources and global explained variance between mMS 2-3 and EEG microstates B-C (rs > 0.60, ps < .002). Hence, the MEG signal can be decomposed into microstates, but mMS brain activity clustering captures phenomena different from EEG microstates. Source reconstruction and task-related modulations link mMS to large-scale networks and localized activities. Thus, mMSs offer insights into brain dynamics and task-specific processes, complementing EEG microstates in studying physiological and dysfunctional brain activity.

Coffee consumption and C-reactive protein levels: A systematic review and meta-analysis

AIMS

Considerable debate exists regarding the association between coffee consumption and C-reactive protein (CRP) levels and the shape of this association. We conducted a meta-analysis to assess the relationship between coffee consumption and CRP levels.

DATA SYNTHESIS

We searched PubMed and Web of Science databases and conducted a hand search as of June 27, 2023. Meta-analyses were conducted using standardized mean differences (SMDs) with random-effects models, based on the geometric mean of CRP from included studies. We identified 13 studies for our systematic review and included 11 cross-sectional studies, involving a total of 66,691 subjects, in our meta-analysis. We found a linear inverse association between coffee consumption and CRP levels (p-value = 0.002) and did not find evidence of a non-linear association (p for non-linearity = 0.13). Compared with the lowest category of coffee consumption (median, non-drinkers), the SMDs of log-transformed CRP levels were -0.02 (95% confidence interval [CI]: -0.05 to 0.00) for the third highest (median, 0.5 cup/day), -0.09 (95% CI: -0.15 to -0.04) for the second highest (median, 2.5 cups/day), and -0.14 (95% CI: -0.25 to -0.04) for the highest category (median, 4.5 cups/day). The inverse association tended to be stronger in women, but the difference by gender was not significant. Compared to the limited number of studies not adjusting for smoking, those that adjusted showed a strong linear inverse association, although the difference was not significant.

CONCLUSIONS

Our findings indicate that coffee consumption is inversely associated with CRP levels. These associations may vary with potential modifiers, including gender and smoking adjustment.

Mortality Awareness: New Directions

Thinking about our own death and its salience in relation to decision making has become a fruitful area of multidisciplinary research across the breadth of psychological science. By bringing together experts from philosophy, cognitive and affective neuroscience, clinical and computational psychiatry we have attempted to set out the current state of the art and point to areas of further enquiry. One stimulus for doing this is the need to engage with policy makers who are now having to consider guidelines on suicide and assisted suicide so that they may be aware of their own as well as the wider populations' cognitive processes when confronted with the ultimate truth of mortality.

The conversation about family planning and desire for children in mental healthcare: Patients' perspective versus Professionals' perspective in a mixed methods study

BACKGROUND

Reproductive health and mental health are intertwined, but studies investigating family planning needs and desire for children in mental healthcare are scarce.

METHODS

We studied the experiences of (former) patients, those with close relationships with the (former) patients (close ones) and mental health professionals (MHP) on discussing family planning and desire for children in mental healthcare. We combined quantitative (two nationwide surveys) and qualitative data (four focus groups) in a mixed-methods approach with sequential analytical design.

RESULTS

Combined data from focus groups (n = 19 participants) and two surveys (n = 139 MHPs and n = 294 (former) patients and close ones) showed that a considerable group of MHPs (64.0%), patients (40.9%) and close ones (50.0%) found that family planning should be discussed by a psychiatrist. However, several obstacles impeded a conversation, such as fear of judgment, lack of time and knowledge and limited opportunity for in-depth exploration of life themes in therapeutic relationships.

CONCLUSIONS

To increase the autonomy of patients in discussing family planning, we suggest MHPs explore the desire to discuss family planning with all patients in the reproductive phase of life, prior to discussing contraceptive care. MHPs should receive education about psychiatric vulnerability in relation to family planning and desire for children, and patients and close ones should be empowered to initiate a conversation themselves.

Investigating the neurodevelopmental correlates of early adolescent-onset emotional problems

BACKGROUND

Emotional problems (EPs) increase sharply after mid-adolescence. Earlier EPs are associated with poorer long-term outcomes, and their underlying mechanisms may differ to later-onset EPs. Given an established relationship between ADHD, autism, and later depression, we aimed to examine associations between neurodevelopmental conditions and correlates and early adolescent-onset EPs.

METHODS

Adolescents in two UK population cohorts, Avon Longitudinal Study of Parents and Children (ALSPAC) and Millennium Cohort Study (MCS), were included. Individuals scoring >6 on the Strengths and Difficulties Questionnaire (SDQ) emotional problems subscale between ages 11-14 were defined as having early adolescent-onset EP, whilst those scoring >6 for the first time at 16-25 were defined as having later-onset EP. We tested associations between early adolescent-onset EP (total cases = 887, controls = 19,582) and ICD-10/DSM-5 neurodevelopmental conditions and known correlates, including: sex, birth complications, low cognitive ability, special educational needs (SEND), and epilepsy. Analyses were conducted separately in ALSPAC and MCS then meta-analysed.

RESULTS

In the meta-analysis of both cohorts, early adolescent-onset EPs were associated with female sex and greater likelihood of low cognitive ability, SEND, autism, ADHD, and reading difficulties. Compared to later-onset EP, early adolescent-onset EPs were associated with male sex, low cognitive ability, SEND, epilepsy, ASD, ADHD, and reading difficulties.

LIMITATIONS

A clinical definition of depression/anxiety was available only in ALSPAC, instead we primarily defined EP via questionnaires, which capture a broader phenotype.

CONCLUSIONS

Individuals with early adolescent-onset EP are likely to have a co-occurring neurodevelopmental condition. Clinicians should consider assessing for neurodevelopmental conditions in young adolescents with EPs.

Spatio-temporal learning and explaining for dynamic functional connectivity analysis: Application to depression

BACKGROUND

Functional connectivity has been shown to fluctuate over time. The present study aimed to identifying major depressive disorders (MDD) with dynamic functional connectivity (dFC) from resting-state fMRI data, which would be helpful to produce tools of early depression diagnosis and enhance our understanding of depressive etiology.

METHODS

The resting-state fMRI data of 178 subjects were collected, including 89 MDD and 89 healthy controls. We propose a spatio-temporal learning and explaining framework for dFC analysis. A yet effective spatio-temporal model is developed to classifying MDD from healthy controls with dFCs. The model is a stacking neural network model, which learns network structure information by a multi-layer perceptron based spatial encoder, and learns time-varying patterns by a Transformer based temporal encoder. We propose to explain the spatio-temporal model with a two-stage explanation method of importance feature extracting and disorder-relevant pattern exploring. The layer-wise relevance propagation (LRP) method is introduced to extract the most relevant input features in the model, and the attention mechanism with LRP is applied to extract the important time steps of dFCs. The disorder-relevant functional connections, brain regions, and brain states in the model are further explored and identified.

RESULTS

We achieved the best classification performance in identifying MDD from healthy controls with dFC data. The top important functional connectivity, brain regions, and dynamic states closely related to MDD have been identified.

LIMITATIONS

The data preprocessing may affect the classification performance of the model, and this study needs further validation in a larger patient population.

CONCLUSIONS

The experimental results demonstrate that the proposed spatio-temporal model could effectively classify MDD, and uncover structural and temporal patterns of dFCs in depression.

Long-Term Neurodevelopmental Outcome of Children With Mild Traumatic Brain Injury

BACKGROUND

To investigate the long-term outcome of pediatric mild traumatic brain injury (mTBI) in terms of neurocognitive, behavioral, and school functioning and to identify clinical risk factors for adverse outcomes.

METHODS

This study describes the follow-up of a prospective multicenter sample of 89 children with mTBI 3.6 years postinjury and 89 neurologically healthy children matched for sex, age, and socioeconomic status. Neurodevelopmental outcomes were assessed using an intelligence test, behavioral questionnaires, computerized neurocognitive tests, and longitudinal (pre- and postinjury) standardized school performance data.

RESULTS

Children with mTBI exhibited intelligence in the average range but had more behavioral problems related to inattentiveness (P = 0.004, d = 0.47) and hyperactive impulsivity (P = 0.01, d = 0.40) and showed poorer neurocognitive performance in information processing stability (P = 0.003, d = -0.55) and Visual Working Memory (P = 0.04, d = -0.39) compared with matched peers. Longitudinal school performance data revealed poorer performance in Technical Reading up to two years postinjury (P = 0.005, d = -0.42) when compared with normative data. Clinical risk factors did not reveal predictive value for adverse outcomes in children with mTBI.

CONCLUSIONS

This study indicates that children with mTBI are at risk of long-term deficits in neurocognitive and behavioral functioning, with longitudinal evidence suggesting shortfalls in school performance up to two years postinjury. Clinical risk factors do not provide a solid basis for long-term neurodevelopmental prognosis. Findings emphasize the importance of, and challenges for, early identification of children at risk for adverse neurodevelopmental outcome after mTBI.

Associations between prenatal stress with offspring inflammation, depression and anxiety

PURPOSE

Few longitudinal studies have investigated the mediating role of inflammation during childhood in associations between prenatal maternal stress and adolescent mental health. The objective of this study was to examine the associations between prenatal maternal stress, concentrations of immune markers at age 9, and symptoms of generalized anxiety disorder (GAD) and depression during adolescence.

METHODS

This study included 3723 mother-child pairs from the Avon Longitudinal Study of Parents and Children (ALSPAC). Prenatal maternal stress was examined using 55 items measured during pregnancy. Inflammation was assessed using serum concentrations of interleukin-6 (IL-6) and C-reactive protein (CRP) when children were 9 years old. GAD and depression were assessed when children were 16 and 18 years of age, respectively. Analyses comprised of structural equation models.

RESULTS

Prenatal maternal stress was associated with higher concentrations of IL-6 in childhood, and with greater symptoms of depression and GAD in adolescence. However, we did not observe associations between prenatal maternal stress and CRP; also, CRP and IL-6 were not associated with depression and GAD. There was no evidence that CRP and IL-6 mediated the associations between prenatal maternal stress and either GAD or depression.

CONCLUSIONS

Prenatal maternal stress is associated with IL-6 levels in childhood, and with GAD and depression during adolescence. Future studies should examine immune activity at multiple points during development in relation to mental health into adulthood to determine whether inflammation at different points during development could increase risk for mental health problems among children whose mothers experienced significant stressors during pregnancy.

Grief Trajectories of Bereaved Parents of Adolescents and Young Adults With Advanced Cancer: A Qualitative Analysis Using Phenomenology

Different parents grieve differently. However, research directed at understanding the important contextual or individual factors that influence the path each bereaved parent takes is lacking. In this qualitative analysis we seek to understand the array of bereaved parent experiences more completely. By deeply diving into one parent dyad using interpretive phenomenology analysis and situating that story within the conventional content analysis of 13 other bereaved parents of adolescents and young adults (AYAs) who died from advanced cancer, we illustrate the roles of religion/spirituality, maintaining a connection, and fulfilling parental roles as elements of grief processing. Clinicians and investigators should consider similar individualized approaches to understanding and supporting the grief experiences of bereaved parents before and after the death of a child.

Efficacy of cognitive behavioral therapy for menopausal symptoms and quality of life in Korean perimenopausal women: A pilot randomized controlled trial

OBJECTIVES

Therapeutic interventions are crucial for perimenopausal women, given the challenging physical and psychological symptoms they face. This study focused on the development and verification of the efficacy of a cognitive behavioral therapy (CBT) protocol designed specifically for Korean perimenopausal women.

STUDY DESIGN

A CBT protocol for perimenopausal women was newly developed based on theory and evidence. Forty menopausal women were randomly assigned to either the CBT group (n = 19) or treatment-as-usual (TAU) group (n = 21). Participants in the CBT group underwent 60-min weekly sessions for eight weeks. The TAU group received standard care from gynecologists.

MAIN OUTCOME MEASURES

At baseline and follow-up, participants completed the Menopausal Rating Scale (MRS), World Health Organization Quality of Life Brief Version (WHOQOL-BREF), Patient Health Questionnaire-9, Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-15 (PHQ-15), Menopause Emotional Symptom Questionnaire (MESQ), and Subjective Memory Complaints Questionnaire.

RESULTS

The CBT group showed significant changes in their MRS (F = 4.18, p = .048), WHOQOL-BREF (7.60, 0.009), GAD-7 (4.61, 0.038), PHQ-15 (5.49, 0.025), and MESQ scores (7.19, 0.011) compared to the TAU group. In the CBT group, changes in GAD-7 scores were correlated with PHQ-15 (ρ = 0.57, p < .05), MESQ (0.57, < 0.05), and WHOQOL-BREF scores (-0.53, < 0.05).

CONCLUSION

CBT prevents the worsening of menopausal and emotional symptoms, anxiety, and quality of life. CBT may have had a therapeutic effect through the following mechanisms: managing anxiety by changing perceptions of menopause through education and training for coping with various menopausal symptoms and improving self-efficacy in symptom management.

Sleep disturbance, suicidal ideation and psychosis-risk symptoms in individuals at clinical high risk for psychosis

Insomnia and suicidal ideation (SI) are common in schizophrenia, including in individuals at clinical high-risk for psychosis (CHR-P). Previous studies have found associations between sleep disturbance, SI, and psychopathology in schizophrenia. We explored these associations in a CHR-P cohort. We leveraged data from CHR-P individuals in the North American Prodrome Longitudinal Studies (NAPLS-3) (n = 688) cohort. We investigated relationships between sleep disturbance (Scale of Prodromal Symptoms [SOPS]; Calgary Depression Scale for Schizophrenia [CDSS], and the Pittsburgh Sleep Quality Index [PSQI]), suicidal ideation (CDSS), and psychosis-risk symptoms. The prevalence of terminal insomnia, sleep disturbance, and SI in NAPLS3 was 25 %, 69 %, and 29 %, respectively. After controlling for potential confounders, multiple indices of sleep disturbance (SOPS, PSQI: OR = 1.05-1.40) were significant indicators of concurrent SI. Terminal insomnia was not associated with conversion to psychosis. Multiple indices of sleep problems were associated with higher total and subscale psychosis-risk symptom scores (β = 0.09-0.39). Sleep problems are prevalent and associated with SI and more severe psychosis-risk symptoms in CHR-P individuals. These findings underscore the importance of designing longitudinal intervention studies to investigate whether the treatment of sleep disturbances may reduce suicidality and symptoms in this population.

Brain-derived neurotrophic factor levels in perinatal depression: A systematic review and meta-analysis

BACKGROUND

This systematic review and meta-analysis aim to synthesize the available evidence and determine the overall brain-derived neurotrophic factor (BDNF) levels in individuals diagnosed with perinatal depression (PND).

METHODS

We performed a thorough search of electronic databases, including PubMed, Embase, PsycINFO, and Web of Science, from their start until April 30, 2023. Our search strategy involved using specific keywords and medical subject headings (MeSH) terms related to BDNF, perinatal, post-partum, and antepartum depression. In the meta-analysis, we employed a random-effects model, and subgroup analyses were conducted to investigate any variations in the results.

RESULTS

A total of 15 studies met the inclusion criteria, of which 10 were used in the quantitative analysis. The meta-analysis demonstrated a significant decrease in BDNF levels in both individuals with antepartum depression (SMD: -0.31; 95% CI: -0.48 to -0.13; p-value = 0.0008; I2 = 71%), and post-partum depression (SMD: -0.61; 95% CI: -0.99 to -0.22; p-value = 0.0002 I2 = 77%). Furthermore, a significantly higher rate of PND among individuals in the lowest BDNF quartile (OR: 2.64; 95% CI: 1.01 to 6.89; p-value = 0.05; I2 = 90%) was seen. The results of subgroup analyses showed a statistically significant effect of the depression assessment tool on overall heterogeneity between studies.

CONCLUSION

This systematic review and meta-analysis provide evidence of lower BDNF protein levels in individuals diagnosed with PND. The results indicate that BDNF dysregulation may play a part in the development of PND. More research is needed to understand the mechanisms behind this and explore potential therapeutic applications.

Approaches to studying emotion using physiological responses to spoken narratives: A scoping review

Narratives are effective tools for evoking emotions, and physiological measurements provide a means of objectively assessing emotional reactions - making them a potentially powerful pair of tools for studying emotional processes. However, extent research combining emotional narratives and physiological measurement varies widely in design and application, making it challenging to identify previous work, consolidate findings, and design effective experiments. Our scoping review explores the use of auditory emotional narratives and physiological measures in research, examining paradigms, study populations, and represented emotions. Following the PRISMA-ScR Checklist, we searched five databases for peer-reviewed experimental studies that used spoken narratives to induce emotion and reported autonomic physiological measures. Among 3466 titles screened and 653 articles reviewed, 110 studies were included. Our exploration revealed a variety of applications and experimental paradigms; emotional narratives paired with physiological measures have been used to study diverse topics and populations, including neurotypical and clinical groups. Although incomparable designs and sometimes contradictory results precluded general recommendations as regards which physiological measures to use when designing new studies, as a whole, the body of work suggests that these tools can be valuable to study emotions. Our review offers an overview of research employing narratives and physiological measures for emotion study, and highlights weaknesses in reporting practices and gaps in our knowledge concerning the robustness and specificity of physiological measures as indices of emotion. We discuss study design considerations and transparent reporting, to facilitate future using emotional narratives and physiological measures in studying emotions.

Adversity and error-monitoring: Effects of emotional context

This study tested whether self-reports of childhood adversity would predict altered error processing under emotional versus non-emotional task conditions. N = 99 undergraduates completed two selective attention tasks, a traditional color-word Stroop task and a modified task using emotional words, while EEG was recorded. Participants also completed self-report measures of adverse and positive childhood experiences, executive functioning, depression, current stress, and emotion regulation. Reports of adversity were robustly correlated with self-reported challenges in executive functioning, even when controlling for self-reported depression and stress, but adversity was not correlated with task performance. With regard to neural markers of error processing, adversity predicted an enhanced error-related negativity and blunted error-positivity, but only during the emotion-word blocks of the task. Moreover, error-related changes in alpha oscillations were predicted by adversity, in a pattern that suggested less error responsiveness in alpha patterns during the emotion block, compared to the color block, among participants with higher adversity. Overall, results indicate alterations in error monitoring associated with adversity, such that in an emotional context, initial error detection is enhanced and sustained error processing is blunted, even in the absence of overt performance changes.

Building resilience: A specialty clinic tailored to older adults at risk for violence and abuse

OBJECTIVE

Both structural (e.g., ageism) and personal (e.g., stigma) barriers hinder older adults' access to and engagement with mental health care. These barriers are particularly problematic for those vulnerable to interpersonal violence and abuse (e.g., due to social isolation). This study presents a quality improvement program aimed at older adults who have experienced significant stressful events, particularly elder mistreatment, within a larger trauma specialty clinic. Leveraging home-based telemedicine, the clinic provides evidence-based psychotherapy tailored to the needs of older adults.

METHODS

From 2021 through 2023, the authors retrospectively examined treatment initiation, engagement, completion, and clinical outcomes among 231 older adults age 60+ who reported trauma that met DSM-5 criterion A criteria for post-traumatic stress disorder, depression, or other mental health comorbid conditions related to their traumatic event. The clinic uses an automated measurement-based care approach that facilitates Quality Improvement projects, allowing the tracking of treatment initiation, engagement, completion, and clinical outcomes for all patients.

RESULTS

The results indicated high treatment completion, high engagement with telemedicine-delivered interventions, and, most importantly, significant changes in clinical outcomes.

CONCLUSION

These findings highlight the importance of expanding telemedicine-based mental health services for older adults, challenging ageist norms, and prioritizing older adults' mental health needs by providing tailored services to this patient population.

Trends in Nonfatal Overdose Rates Due to Alcohol and Prescription and Illegal Substances in Colombia, 2010‒2021

Objectives. To examine drug overdoses in Colombia by type of substance, sex, age, and intent using data from a health surveillance system from 2010 to 2021. Methods. We characterized data by year, type of substance, and sociodemographic variables. We calculated age-adjusted overdose rates by substance type, sex, age groups, and intent. We used Poisson regression models to examine trend differences across sex and age groups. Results. Age-adjusted rates of drug overdoses increased from 8.51 to 40.52 per 100 000 during 2010 to 2021. Men, compared with women, had higher overdose rates for every substance, except for opioids and psychotropics. Drug overdose rates involving cannabis and stimulants increased steadily until 2017 but decreased afterward. Overdose rates involving psychotropic medication increased greatly during 2018 to 2021, mainly because of intentional overdoses in young women. Conclusions. Overdoses involving illegal drugs decreased in recent years in Colombia; however, the continuous increase in intentional psychotropic overdose rates highlights the need for prevention efforts to curb this trend. Health surveillance systems are an important tool that can guide overdose prevention efforts in countries with limited data resources.

Temperament in Early Childhood Is Associated With Gut Microbiota Composition and Diversity

Temperament is a key predictor of human mental health and cognitive and emotional development. Although human fear behavior is reportedly associated with gut microbiome in infancy, infant gut microbiota changes dramatically during the first 5 years, when the diversity and composition of gut microbiome are established. This period is crucial for the development of the prefrontal cortex, which is involved in emotion regulation. Therefore, this study investigated the relationship between temperament and gut microbiota in 284 preschool children aged 3-4 years. Child temperament was assessed by maternal reports of the Children's Behavior Questionnaire. Gut microbiota (alpha/beta diversity and genera abundance) was evaluated using 16S rRNA sequencing of stool samples. A low abundance of anti-inflammatory bacteria (e.g., Faecalibacterium) and a high abundance of pro-inflammatory bacteria (e.g., Eggerthella, Flavonifractor) were associated with higher negative emotionality and stress response (i.e., negative affectivity, β = -0.17, p = 0.004) and lower positive emotionality and reward-seeking (i.e., surgency/extraversion, β = 0.15, p = 0.013). Additionally, gut microbiota diversity was associated with speed of response initiation (i.e., impulsivity, a specific aspect of surgency/extraversion, β = 0.16, p = 0.008). This study provides insight into the biological mechanisms of temperament and takes important steps toward identifying predictive markers of psychological/emotional risk.

Gender-specific factors of suicidal ideation among high school students in Yunnan province, China: A machine learning approach

BACKGROUND

Suicidal ideation (SI) assumes a pivotal role in predicting suicidal behaviors. The incidence of SI among high (junior and senior) school students is significantly higher than that of other age groups. The aim of this study is to explore the gender differences in SI among high school students in Yunnan Province.

METHOD

A total of 6180 students in grades 7-12 in Yunnan province, China from May 2021 to May 2022 participated in this survey. Univariate analysis was employed to describe the influencing factors of male and female students' SI. Subsequently, data were stratified by gender. Adopting machine learning technique, including Least Absolute Shrinkage and Selection Operator (Lasso) and Boruta algorithm, and logistic regression model to estimate the direction and effect magnitude of the influencing factors.

RESULTS

The prevalence of SI was significantly higher for females (31.34 %) than males (16.73 %). The logistic regression model was established using the variables screened by Boruta algorithm, indicated that anxiety, depression, suffering emotion abuse or emotion neglect in childhood, non-suicidal self-injury, evening chronotype are common risk factors for SI in male and female students. Notably, female students who exhibited aggressive behavior, have experienced bullying, and were in the junior high school learning stage were more likely to report SI than their male counterparts.

CONCLUSIONS

Females showed more vulnerability to SI than males especially among females in junior high school, reporting aggressive behavior and bullying experiences. Tailored prevention strategies, informed by these gender-related distinctions, should be developed and implemented.

Understanding Major Depressive Disorder in Singapore: Insights from the second Singapore Mental Health Study (SMHS 2016)

BACKGROUND

Major Depressive Disorder (MDD) poses significant public health challenges globally and in Southeast Asia, with substantial impairment and disease burden. Understanding its prevalence and associated risk factors is crucial for effective intervention.

METHODS

This study aims to describe the prevalence shifts, correlates, and comorbidities of MDD in Singapore. Data were collected from the second Singapore Mental Health Study (SMHS 2016), a national cross-sectional survey comprising 6126 adult residents. The WHO Composite International Diagnostic Interview assessed MDD and comorbidities. Statistical analyses, including logistic regression, were conducted to examine the associations and trends.

RESULTS

The lifetime weighted prevalence of MDD in SMHS 2016 was 6.2 %, with an overall increase from 5.8 % in 2010. Significant associations were found between MDD and age, marital status, and comorbid physical disorders. Young adults and divorced/separated individuals exhibited higher MDD prevalence. Chronic pain was significantly associated with MDD.

LIMITATIONS

The study's cross-sectional design limits causal inference, and selective non-response might affect prevalence estimates. However, the study benefits from a large, nationally representative sample and standardized methodologies.

CONCLUSIONS

Young and middle-aged adults, and divorced/separated individuals demonstrate elevated MDD prevalence, warranting targeted interventions. Individuals with comorbidities, particularly chronic pain, constitute a high-risk and vulnerable population. Comprehensive assessment and treatment plans should involve multidisciplinary teams and integrated care approaches to better address the complex needs of these individuals. Our study also highlights specific interventions for schools, families, communities, and workplaces. Despite Singapore's relatively low prevalence compared to Western nations, MDD remains cross-culturally valid emphasizing the need for early intervention and preventive public health measures.
