Objective. Posttraumatic stress disorder (PTSD) is linked with impaired intimate relationships in postpartum women, yet less is known about couple-level manifestations of posttraumatic psychopathology and potential associations with relationship functioning for mothers and fathers during this critical time. Method. In a predominately low-to-middle income sample of 867 mother-father couple dyads assessed six months following the birth of a child, two analytic methods—a data-driven dyadic latent profile analysis and hypothesis-driven a priori categorization approach—evaluated whether discrete subgroups of couples could be identified based on both partners’ PTSD symptoms. Structural equation models then tested associations between identified subgroups with (1) self-reported relationship quality and (2) interviewer-rated relationship stress. Results. Three couple-level PTSD symptom groupings were common to both methods: both low, mother low-father high, and mother high-father low. Dyad-level PTSD symptom patterns were differentially related to relationship dysfunction for mothers and fathers, although mixed findings emerged across methods regarding the relevance of which partner had elevated symptoms for relationship functioning in PTSD symptom-discordant couples. Individuals in dyads characterized by at least one partner with elevated PTSD symptoms consistently exhibited greater relationship dysfunction—indexed both subjectively and objectively—compared to dyads where both partners had low symptoms. Conclusions. Couple-level typologies of PTSD symptoms can be identified using data- and hypothesis-driven approaches, with generally concordant results. Dyadic patterns of PTSD symptoms are relevant to relationship functioning for both mothers and fathers during the postpartum period and may help to inform more targeted intervention efforts to support couples who are parenting.

Background. Despite the growing prevalence of internet usage among young people, the relationships between internet addiction, online social anxiety, fear of missing out (FoMO), and interpersonal sensitivity remain uncertain, intricate, and multifaceted. To gain insight into the underlying psychological mechanisms, we employed network analysis to explore the interconnections between them. This endeavor may provide fresh opportunities for intervention and treatment. Methods. In this study, 470 participants were assessed at age from 18 to 22 (M = 20.18 years, SD = 1.861) years. Network analysis was used to examine the connections between symptoms, and statistical measures were applied to assess the stability of the network model. Results. Online social anxiety and interpersonal sensitivity had the strongest associations with other symptoms in the network, with “Evaluation anxiety” having the highest expected influence centrality, followed by “Privacy concern anxiety,” “Need for approval,” “Suspicion,” and “vulnerability.” The FoMO symptom, “Fear of missing information,” had the strongest direct relation to internet addiction. “Evaluation anxiety” and “Fear of missing information” played a key role in bridging internet addiction and interpersonal sensitivity. Additionally, the structure distribution of edge weights had a significant difference between gender. Conclusions. Our findings indicated that FoMO, interpersonal sensitivity, and online social anxiety likely play a significant role in the development and continuation of internet addiction. Interpersonal sensitivity seems to contribute to increased online social anxiety, FoMO, and the development of internet addiction, indicating that targeting these symptoms may help reduce negative online behavior and psychological burden.

Personality traits are considered potential risk or protective factors for learning and psychological adjustment. This is a concern in higher education settings, which comprise mostly youth in emerging adulthood. The purpose of this study is to apply a person-centered approach to identify personality profiles of university students based on their character traits and then evaluate whether some clusters predict differences in emotional distress and coping strategies. We conducted a cross-sectional web-based survey with 467 southern Italian undergraduate university students (M = 21.8, SD = 3.69). Students completed an anonymous online survey and self-report questionnaires measuring sociodemographic characteristics, personality traits (Personality Inventory for DSM-5), emotional distress (General Anxiety Disorders-7, Patient Health Questionnaire-9), and coping strategies (Brief-COPE). Two distinct clusters were identified, differing in relation to maladaptive personality traits. One was characterized by high maladaptive personality traits, comprising 45.6% of the sample population. This high-risk profile evidenced higher levels of negative affect, detachment, psychoticism, antagonism, and disinhibition. A second cluster, with low maladaptive personality traits, represented the remainder of the sample. Participants featuring high maladaptive personality traits reported lower functioning in terms of avoidant coping strategies in comparison to the second low-risk cluster. Generating profiles of latent traits, such as in cluster analysis, can enhance a more profound theoretical understanding of underlying patterns within personality traits. This can enable higher education settings to meet variations in student needs by adapting their support services and interventions. Students can be trained to use coping strategies more effectively and efficiently.

Aim. To determine serum concentrations of leptin and ghrelin in patients with major depressive disorder (MDD) before and after vitamin D3 supplementation. Methods. A total of 72 participants were recruited in this study (40 MDD patients and 32 healthy controls). MDD was diagnosed by using Beck’s Depression Inventory (BDI) scale. Blood samples were collected from all participants at the beginning of the study to determine baseline serum 25(OH)D3, leptin, and ghrelin concentrations. Patients were then treated weekly with vitamin D3 (50,000 IU) for 3 months, and blood samples were collected again by the end of the study. Results. At baseline, serum leptin concentrations were significantly higher in MDD patients than in healthy controls. In contrast, serum ghrelin concentrations were significantly lower compared to those in healthy controls. After supplementation with vitamin D3 for three months, MDD patients showed improvements characterized by a decrease in their BDI’s scores and an increase in their serum vitamin D and ghrelin concentrations. No effects of vitamin D3 supplementation were seen on serum leptin concentration. Conclusions. The antidepressant effects of vitamin D3 supplementation could be mediated by ghrelin but not leptin.

Working memory updating plays a critical role in executive function. Few studies explored the working memory updating in socially anxious individuals. In this study, we wanted to explore the working memory updating in socially anxious individuals. We studied this issue by instructing participants to perform an emotional 2-back task, and recording their response time and accuracy. We found that high socially anxious individuals showed significant longer response time in positive word condition than that of negative and neutral words. But there was no significant difference in word type in low socially anxious group. In accuracy, we did not observe any significant difference in group, word type, and their interaction. These results indicate that socially anxious individuals have deficits in positive content updating, which have an important implication for developing method to reduce social anxiety.

The objectives of this study were to investigate the interaction of mitochondrial DNA (mtDNA) and lifestyle factors in the development of psychiatric disorders and to gain greater insight into their pathogenesis and comorbidity. We analyzed data from approximately 150,000 individuals from the UK Biobank. Mitochondrial gene-by-environment interaction studies (mtGEIS) were performed to assess the relationships between mtDNA and psychiatric disorders, such as anxiety, depression, and self-harm. These disorders were defined using diagnostic and severity indicators derived from the General Anxiety Disorder (GAD-7) and Patient Health Questionnaire (PHQ-9). Smoking and drinking behaviors were characterized based on UK Biobank criteria. For the mtGEIS, logistic and linear regression models from PLINK 2.0 were employed, accounting for covariates like age, sex, PC1-10, Townsend Deprivation Index (TDI), and educational attainment. We also conducted sex-stratified analyses to detect any gender-specific effects. Our findings highlighted significant associations between mtDNA and three psychiatric disorders. Moreover, the interplay between mtDNA and lifestyle factors showed significant associations with psychiatric disorders (all P values < 0.05). Specifically, two mutant loci, T5004C (B_{Anx_self} = −0.0026, B_{Dep_self} = −0.0024, B_Self−harm = −0.0018) and G9123A (B_{Anx_self} = −0.0030, B_{Dep_self} = −0.0024, B_Self−harm = −0.0017), were found to reduce the risk of three disorders after interacting with alcohol. Sex-specific differences were also observed. In summary, the expression of mitochondrial genes could be modulated by lifestyle factors like smoking and drinking, potentially affecting psychiatric disorders. These habits might influence mitochondrial respiratory chain activity and the replication and transcriptional regulation of mitochondrial genes, culminating in changes in mitochondrial functionality and subsequently psychiatric disorders.

Background. Longitudinal studies investigating the prevalence of comorbid anxiety and depression (CAD) and its risk factors during the perinatal period are limited. The objective of this longitudinal study was to describe the prevalence and risk factors of CAD among pregnant and postpartum women in China. Methods. From the Population Health Data Archive of the National Population Health Data Center, 1,941 Chinese pregnant or postpartum women who were surveyed for both depressive and anxiety symptoms during and after pregnancy were included in the study. This population-based longitudinal study was conducted between March 2017 and March 2022. The self-rating anxiety scale and self-rating depression scale were used to assess anxiety and depression symptoms at four time points throughout the perinatal period. The generalized estimation equation model was used to identify sociodemographic, obstetric, and mental health factors for CAD. Results. The prevalence of CAD was 15.67%, 8.36%, 11.64%, and 13.24% in the first, second, and third trimesters and postpartum, respectively. A higher proportion of women reporting, compared to women with single anxiety or depression, CAD during and after pregnancy were primiparas (OR = 1.32, 95% CI 1.06-1.65), having a smoking history (OR = 1.51, 95% CI 1.05-2.18), and having dissatisfied marital relationship (OR = 1.97, 95% CI 1.28-3.06). Women conceived with assisted reproductive treatment were reported to be less likely to have CAD (OR = 0.69, 95% CI 0.55-0.86). Conclusions. These findings highlight that CAD is relatively common in pregnant and postpartum women and recommend targeted interventions for higher risk women, specifically primiparas with a history of smoking and dissatisfied marital relationships.

This study is aimed at revealing the risk factors, prognosis, influence on offspring, and genetic architecture of perinatal depression (PD) classified based on the depressive symptom trajectory. Pregnant women with no history of major depressive disorder (MDD) were recruited and followed up with their offspring from 1 to 5 years postpartum. Using four self-report questionnaires in the perinatal period, PD was classified into four subtypes: pregnancy, early postpartum, late postpartum, and chronic PD. Risk factors, depressive symptom trajectory from 1 to 5 years postpartum, and child behavior problems were compared among the four PD subtypes. Genome-wide association studies (GWASs) were conducted for each subtype. The relationships between the PD subtypes and polygenic risk scores (PRS) for MDD, a psychiatric disorder, and premenstrual syndrome (PMS), a hormonal disorder, were examined. Among 12,338 participants, 1,145 (9.3%) developed pregnancy PD, 856 (6.9%) developed early postpartum PD, 382 (3.1%) developed late postpartum PD, and 1,048 (8.5%) developed chronic PD. Depressive symptoms decreased to 61.0%–73.3% in the 5 years postpartum. The relationship between risk factors and PD varied based on the PD subtype. Additionally, chronic PD increased the risk of child behavior problems by 2- to 3-fold. The GWASs uncovered five significant variants in different loci depending on PD subtypes, suggesting a subtype-specific genetic architecture. The PRS for MDD was related to pregnancy, early postpartum, and chronic PD, while that for PMS was related to late postpartum PD. It was concluded that PD is heterogeneous depending on the depressive symptom trajectory. Thus, specific prevention and treatment strategies are needed.

Background. While the brain correlates of major depressive disorder (MDD) have been extensively studied, there is no consensus conclusion so far. Various meta-analyses tried to determine the most consistent findings, but the results are often discordant for grey matter volume (GMV) atrophy and hypertrophy. Applying rigorous and stringent inclusion criteria and controlling for confounding factors, such as the presence of anxiety comorbidity, we carried out two novel meta-analyses on the existing literature to unveil MDD signatures. Methods. A systematic literature search was performed up to January 2023. Seventy-three studies on MDD patients reporting GMV abnormalities were included in the first meta-analysis, for a total of 6167 patients and 6237 healthy controls (HC). To test the effects of anxiety comorbidity, we conducted a second meta-analysis, by adding to the original pure MDD sample a new cohort of MDD patients with comorbid anxiety disorders (308 patients and 342 HC). An activation likelihood estimation (ALE) analysis and a coordinate-based mapping approach separate for atrophy and hypertrophy were used to identify common brain structural alterations among patients. Results. The pure MDD sample exhibited atrophy in the left insula, as well as hypertrophy in the bilateral amygdala and parahippocampal gyri. When we added patients with comorbid anxiety to the original sample, bilateral insula atrophy emerged, whereas the hypertrophy results were not replicated. Conclusions. Our findings revealed important structural alterations in pure MDD patients, particularly in the insula and amygdala, which play key roles in sensory input integration and in emotional processing, respectively. Additionally, the amygdala and parahippocampal gyrus hypertrophy may be related to MDD functional overactivation to emotional stimuli, rumination, and overactive self-referential thinking. Conversely, the presence of anxiety comorbidity revealed separate effects which were not seen in the pure MDD sample, underscoring the importance of strict inclusion criteria for investigations of disorder-specific effects.

Objectives. It is a high risk for adolescents with first-episode major depressive disorder (MDD) to commit suicide. However, few studies reported the effect of modified electroconvulsive therapy (MECT) in first-episode antipsychotic-naive MDD adolescents. Methods. The study explores the alternations of regional homogeneity of modified electroconvulsive therapy to treat the first-episode antipsychotic-naive major depressive disorder. 72 first-episode MDD patients were recruited from Tianyou Hospital Affiliated to Wuhan University of Science and Technology from October 2017 to May 2020, and 65 of 72 completed the trial. Results. Before MECT treatment, ReHo values of the bilateral cerebellum and left cuneus were higher, and ReHo value of left postcentral and supramarginal gyrus was lower in MDD patients compared to healthy subjects (HS). After treatment, the MDD patients have higher ReHo values of the right insula and postcentral gyrus, while left fusiform gyrus were lower than the pretreatment. Compared to the HS, the ReHo values of left lingual gyrus, right calcarine cortex, and right mid occipital thalamus were higher in the posttreatment. In the posttreatment, left calcarine cortex and right cerebrum were lower than in healthy subjects. Conclusions. The study confirmed that MECT improves psychotic symptoms in patients with first-episode antipsychotic-naive MDD. These results further contributed to a more tailored treatment approach to MDD from the pathophysiological and neuroimaging views.
