Background: The incidence of various mood disorders and temperaments in ADHD patients is well-documented, irrespective of age. These temperamental differences cause emotional and behavioral instability, impacting individual and social functioning, and overall quality of life. This study evaluates different temperaments in adults with ADHD compared to those without ADHD. Methods: This case–control study was performed on 75 adult ADHD patients as the case group and 75 adults without ADHD as the control group. A demographic questionnaire and a shortened Persian version of the TEMPS-A questionnaire were given and completed to the people included in the study to assess different mood temperaments. Results: Comparing different components of mood temperaments between the patients with and without ADHD showed significantly higher mean scores for irritable, anxious, depressed, and cyclothymic temperaments in those with ADHD as compared to a control group. In the group suffering from ADHD, women had significantly higher mean scores for dysthymic and anxious temperaments as compared to men, while the mean score for cyclothymic temperaments was significantly higher in men than in women. A high academic degree was associated with lower scores for mood temperaments, while mood temperaments were independent of patients' age. Conclusions: The higher score of various mood temperaments in patients with ADHD compared to people without this disorder is completely predictable, and this score can potentially affect the gender of the patients as well as their education level. Given the higher scores of temperamental traits in patients with adult ADHD, implementing screening programs aimed at identifying temperamental disorders in these patients is highly emphasized.

The thymus is the central organ involved with T-cell development and the production of naïve T cells. During normal aging, the thymus undergoes marked involution, reducing naïve T-cell output and resulting in a predominance of longlived memory T cells in the periphery. Outside of aging, systemic stress responses that induce corticosteroids (CS), or other insults such as radiation exposure, induce thymocyte apoptosis, resulting in a transient acute thymic involution with subsequent recovery occurring after cessation of the stimulus. Despite the increasing utilization of immunostimulatory regimens in cancer, effects on the thymus and naïve T cell output have not been well characterized. Using both mouse and human systems, the thymic effects of systemic immunostimulatory regimens, such as high dose IL-2 (HD IL-2) with or without agonistic anti-CD40 mAbs and acute primary viral infection, were investigated. These regimens produced a marked acute thymic involution in mice, which correlated with elevated serum glucocorticoid levels and a diminishment of naïve T cells in the periphery. This effect was transient and followed with a rapid thymic "rebound" effect, in which an even greater quantity of thymocytes was observed compared to controls. Similar results were observed in humans, as patients receiving HD IL-2 treatment for cancer demonstrated significantly increased cortisol levels, accompanied by decreased peripheral blood naïve T cells and reduced T-cell receptor excision circles (TRECs), a marker indicative of recent thymic emigrants. Mice adrenalectomized prior to receiving immunotherapy or viral infection demonstrated protection from this glucocorticoid-mediated thymic involution, despite experiencing a substantially higher inflammatory cytokine response and increased immunopathology. Investigation into the effects of immunostimulation on middle aged (7-12 months) and advance aged (22-24 months) mice, which had already undergone significant thymic involution and had a diminished naïve T cell population in the periphery at baseline, revealed that even further involution was incurred. Thymic rebound hyperplasia, however, only occurred in young and middle-aged recipients, while advance aged not only lacked this rebound hyperplasia, but were entirely absent of any indication of thymic restoration. This coincided with prolonged deficits in naïve T cell numbers in advanced aged recipients, further skewing the already memory dominant T cell pool. These results demonstrate that, in both mice and humans, systemic immunostimulatory cancer therapies, as well as immune challenges like subacute viral infections, have the potential to induce profound, but transient, glucocorticoid-mediated thymic involution and substantially reduced thymic output, resulting in the reduction of peripheral naive T cells. This can then be followed by a marked rebound effect with naïve T cell restoration, events that were shown not to occur in advanced-aged mice. [ABSTRACT FROM AUTHOR]

Suicidal thoughts and behaviors (STBs) in children are an escalating public health concern. This study focused on 1 understudied candidate risk factor, namely, preschool-onset major depressive disorder (PO-MDD), as a predictor of persistent and emerging STBs from early childhood into preadolescence. Participants were 137 children 8 to 12 years of age who met criteria for PO-MDD when they were 3 to 6 years of age, and a nondepressed sample of 53 age-, income-, and sex-matched peers. STBs were reported by caregivers (preschool, preadolescence) and children (preadolescence) using age-appropriate diagnostic interviews. By preadolescence, children who had PO-MDD were 7.38 times more likely than their peers to have endorsed STBs after early childhood (p <.001; 67.9% vs 22.6%), including 6.71 times more likely to have engaged in suicide behaviors/attempts (p =.012; 21.9% vs 3.8%); they were also 8.98 times more likely to have endorsed STBs over the prior month (p =.005; 26.3% vs 3.8%). Similar findings emerged when limiting the PO-MDD group to children without preschool STBs, and when controlling for externalizing comorbidities, implicating PO-MDD as a unique diagnostic predictive risk factor. However, children who had PO-MDD with STBs were 3.46 times more likely than children who had PO-MDD without STBs to endorse later STBs (p =.018; 83.1% vs 54.2%), indicating substantial continuity of preschool STBs alongside strikingly high rates of emerging STBs into preadolescence. This longitudinal study explores preschool onset major depressive disorder (PO-MDD) as a predictor of having suicidal thoughts or attempting suicide by age 12. 137 children aged 8 to 12 years who met criteria for PO-MDD when they were 3 to 6 years of age and 53 non-depressed peers were included in the study. The study found that preadolescents who had experienced preschool-onset depression were 6.14 times more likely to experience active suicidal thoughts and 8.03 times more likely to have made a suicide attempt by age 12 when compared to preadolescents who did not experience preschool depression. Results suggest that children with preschool-onset depression would likely benefit from increased suicide screening, proactive safety planning and early interventions. PO-MDD is a strong risk factor for the emergence and persistence of STBs into preadolescence. Children with PO-MDD would likely benefit from increased suicide screening, proactive safety planning, and early interventions. [ABSTRACT FROM AUTHOR]

Objectives: The current study aimed to examine: (1.1) causal beliefs about adolescent depression in a sample of adolescents with a clinical depression and their mothers and fathers; (1.2) within‐family overlap of causal beliefs; (2.1) mothers' and fathers' reflected causal beliefs about their child's perspective; (2.2) the accuracy of mothers' and fathers' reflected causal beliefs as related to their child's causal beliefs. Design: Qualitative study using a within‐family approach. Methods: Adolescents with a current clinical depression (MDD/dysthymia; N = 34) and their parents (N = 34 mothers, N = 26 fathers) were independently interviewed about their causal beliefs about the adolescents' depression. Parents were additionally interviewed about their perception of their child's causal beliefs (i.e., reflected causal beliefs). Results: The causal beliefs most frequently mentioned by adolescents, mothers and fathers are: characteristics of the child, social factors, school and various stressful experiences. Parent–child overlap was relatively low, specifically for the themes of bewilderment, cumulative effect and stressful life events, whereas overlap was relatively high for themes of social factors, school and stressful experiences outside of the family. Parents were relatively accurate in their reflected causal beliefs, but tended to underestimate their child's insights into possible causes of their depression. Accuracy of parents' reflected causal beliefs was particularly low for the theme cumulative effect and high for social factors. Conclusions: The various causal beliefs of adolescents and their parents could be used in therapeutic setting. Future research could examine whether (guided) conversations may promote alignment within families and treatment efficacy. [ABSTRACT FROM AUTHOR]

• First systematic review looking at suPAR as a biomarker in a psychiatric population. • Primary analyses showed elevated suPAR levels in those with depressive disorder. • Secondary analysis showed elevated plasma suPAR levels in those with schizophrenia. • Two studies found no difference in serum suPAR levels between groups. • Chronic inflammatory dysregulation may contribute to the pathogenesis of these disorders. There is some evidence of an association between inflammation in the pathogenesis of mental disorders. Soluble urokinase plasminogen activator receptor (suPAR) is a biomarker of chronic inflammation, which provides a more stable index of systemic inflammation than more widely used biomarkers. This review aims to synthesise studies that measured suPAR concentrations in individuals with a psychiatric disorder, to determine if these concentrations are altered in comparison to healthy participants. Comprehensive literature searches from inception to October 2023 were conducted of five relevant databases (PubMed, Web of Science, Embase, Scopus, APA PsychInfo). Random-effects meta-analyses were performed to compare the standardised mean difference of blood suPAR levels (i.e. plasma or serum) for individuals with any psychiatric disorder relative to controls. Separate meta-analyses of suPAR levels were conducted for individuals with schizophrenia or other psychotic disorder and depressive disorder. Risk of bias was assessed using the Newcastle Ottawa Scale. Post-hoc sensitivity analyses included excluding studies at high risk of bias, and analyses of studies that measured suPAR concentrations either in serum or in plasma separately. The literature search identified 149 records. Ten full-text studies were screened for eligibility and 9 studies were included for review. Primary analyses revealed no significant difference in suPAR levels between individuals with any psychiatric disorder compared to controls (k = 7, SMD = 0.42, 95 % CI [−0.20, 1.04]). However, those with depressive disorder had elevated suPAR levels relative to controls (k = 3, SMD = 0.61, 95 % CI [0.34, 0.87]). Similarly, secondary analyses showed no evidence of a significant difference in suPAR levels in individuals with any psychiatric disorder when studies at high risk of bias were excluded (k = 6, SMD = 0.54, 95 % CI [−0.14, 1.22]), but elevated suPAR concentrations for those with schizophrenia or other psychotic disorder were found (k = 3, SMD = 0.98, 95 % CI [0.39, 1.58]). Furthermore, studies that analysed plasma suPAR concentrations found elevated plasma suPAR levels in individuals with any psychiatric disorder relative to controls (k = 5, SMD = 0.84, 95 % CI [0.38, 1.29]), while studies measuring serum suPAR levels in any psychiatric disorder did not find a difference (k = 2, SMD = -0.61, 95 % CI [−1.27, 0.04]). For plasma, elevated suPAR concentrations were also identified for those with schizophrenia or other psychotic disorder (k = 3, SMD = 0.98, 95 % CI [0.39, 1.58]). When studies measuring either only serum or only plasma suPAR were considered, no significant difference in suPAR levels were observed between psychiatric disorder groups, although significantly elevated suPAR levels were detected in those with moderate to severe depressive disorder. However, plasma suPAR levels were significantly elevated in those with any psychiatric disorder relative to controls, while no difference in serum samples was found. A similar finding was reported for schizophrenia or other psychotic disorder. The plasma findings suggest that chronic inflammatory dysregulation may contribute to the pathology of schizophrenia and depressive disorder. Future longitudinal studies are required to fully elucidate the role of this marker in the psychopathology of these disorders. [ABSTRACT FROM AUTHOR]

Depressive symptoms and personality traits covary in adolescents, but our understanding of the nature of this relation is limited. Whereas a predisposition explanation posits that specific personality traits increase the vulnerability for developing depression, a scar explanation proposes that depression may alter premorbid personality. Attempts to test these explanatory models have relied on analyses that conflate within-person changes and between-person differences, which limits the implications that can be drawn. Moreover, research on the early adolescent years is lacking. The present study therefore examined within-person associations between depressive symptoms and Big Five personality traits across ages 10 to 16. Children (n = 817; 49.9% boys) and parents from two birth cohorts in Trondheim, Norway, were assessed biennially with clinical interviews capturing symptoms of major depressive disorder and dysthymia, and self-reported Big Five personality traits. Analyses were conducted using a random intercept cross-lagged panel model, which accounts for all unmeasured time-invariant confounding effects. Increased Neuroticism predicted an increased number of depressive symptoms—and increased depressive symptoms predicted increased Neuroticism—across ages 10 to 14. Moreover, increased depressive symptoms forecast reduced Extraversion across ages 10 to 16, and reduced Conscientiousness from ages 12 to 14. Increases in Neuroticism may contribute to the development of depressive symptoms—in line with the predisposition model. As regards the scar model, depression may have an even wider impact on personality traits: increasing Neuroticism and reducing Extraversion and Conscientiousness. These effects may already be present in the earliest adolescent years. [ABSTRACT FROM AUTHOR]

Background: Emerging issues in the management of major depressive disorder (MDD) comprise a nonadherence to treatment and treatment failures, depressive recurrence and relapses, misidentification of incoming exacerbated phases and consequently, a chronification of depression. While antidepressant drugs constitute the standard of care for MDD, effective psychosocial interventions are needed to reduce rehospitalizations and other adverse events. The present study primarily investigated the effects and impact of implementing a structured psychoeducational intervention on the clinical course of MDD. Methods: A non-randomized comparative, pragmatic, pilot, single-center study of adults with nonpsychotic moderate or severe episode of MDD recently discharged from a psychiatric hospitalization. The consecutive subjects were allocated either to the intervention group (N=49) or to the attention control group (N=47), based on their preference. The psychoeducational intervention was based on a modified Munoz's Depression Prevention Course. Subjects were followed up prospectively for two years. Results: The absolute changes in Beck anxiety inventory scale, Zung's depression questionnaire, and Montgomery and Äsberg depression rating scale (MADRS) total scores at 6-month follow-up were comparable between the two groups. There were lower rates of the rehospitalization within one year (2.1% vs. 16.7%; P<0.001) and less rehospitalizations after one year (6.3% vs. 25%; P<0.001), lower rates of the ongoing sickness absence (11.5% vs. 29.2%; P<0.001), less persons with disability due to MDD at 1-year follow-up (1% vs. 11.5%; P=0.002), and less nonadherent subjects who self-discontinued treatment (6.3% vs. 28.1%; P<0.001) among participants in the intervention group compared to the control group. The disability due to MDD at 1-year follow-up was predicted by the absence of the psychoeducational intervention (P=0.002) and by the MADRS total score at 6-month follow-up (OR 1.10; 95% CI 1.003-1.195; P=0.044). Qualitative data indicated the intervention was desired and appreciated by the participants, as well as being practical to implement in Slovakian clinical settings. Conclusion: The results suggest the psychoeducational intervention based on a modified Munoz's Depression Prevention Course has beneficial effects in adults with MDD recently discharged from a psychiatric hospitalization. The findings implicate the psychoeducational intervention may offer a new approach to the prevention of depressive relapses. [ABSTRACT FROM AUTHOR]

Background: Suicidal ideation is a depression symptom which represents a key (cognitive) component of suicidality and plays an important role in suicide risk detection, intervention, and prevention. Despite existing research showing the importance of certain factors of depression symptoms and suicidal ideation, less is known about the interaction between the various risk and protective factors. The aim of the study was to examine whether living conditions characteristics and personal circumstances during the COVID-19 pandemic predicted the presence of depression symptoms and suicidal ideation among tertiary students and whether resilience and social support can mitigate the detrimental effects of difficult life circumstances. Method: A large online cross-sectional study was conducted in March 2021 among 4,645 Slovenian tertiary students. Hierarchical multiple regression and hierarchical logistic regression methods were used to assess and compare the effect of life circumstances variables, as opposed to resilience and social support, on depression symptoms and suicidal ideation. Results: Female gender, single relationship status, living alone, a higher degree of household conflict, having a history of mental illness and chronic disease diagnosis were significant predictors of depression scores. All but gender were also predictors of suicidal ideation. Household conflict and a history of mental illness were the factors showing the strongest effect in both cases. On the other hand, social support and, in particular, resilience proved to be strong protective factors against depression symptoms and suicidal ideation. After accounting for one's resilience and social support, the explained variance in depression scores was more than doubled, while the harmful effect of household conflict and history of mental illness significantly decreased. Conclusions: The findings stress the importance of one's resilience and social support and explain why some people manage to maintain mental well-being despite finding themselves in difficult life circumstances, which was the case for many tertiary students during the COVID-19 pandemic. These insights may inform preventive efforts against developing suicidal ideation and may be used as support for the design and implementation of interventions for improving resilience and social support from childhood onward.

Introduction: Major depressive disorder (MDD), postpartum depression (PPD), and insomnia are neuropsychological conditions in which zuranolone is used to improve symptoms and prognosis of the disorder. This meta-analysis aimed to determine the efficacy of zuranolone in comparison to other drugs used for treating these conditions. Methods: This meta-analysis included patients aged between 18 and 75 years who were diagnosed with major depressive disorder and postpartum depression with or without insomnia and were administered zuranolone for treatment. Only randomized controlled trials (RCTs) were included, and animal studies were excluded. The databases used were PubMed, Scopus, Cochrane, and Clinicaltrials.gov, with MeSH terms and relevant keywords for (Zuranolone) and (Depression). The Cochrane risk of bias tool was used for quality assessment. Results: The meta-analysis included eight RCTs that analyzed data from 2031 patients. The meta-analysis revealed statistically significant changes in the Hamilton Depression Rating Scale (HAM-D), Montgomery-Åsberg Depression Rating Scale (MADRS), Hamilton Anxiety Rating Scale (HAM-A), and treatmentemergent adverse effects (TEAE) scores in the PPD subgroup. HAM-D and TEAEs scores were also significant in the MDD subgroup, but the changes in the MADRS, HAM-A, and Bech-6 scores were insignificant. Serious adverse events were insignificant in all subgroups. Conclusion: Meta-analysis found a significant improvement in depressive symptoms with zuranolone treatment, especially on day 15. This suggests that zuranolone is a promising therapeutic option for patients with MDD and PPD with or without insomnia. [ABSTRACT FROM AUTHOR]

We examined trends in depression among 17-year-olds to understand the contribution of incoming students to the demand for collegiate mental health services. Seventeen-year-olds (N = 32,325) from the National Surveys on Drug Use and Health (NSDUH) for 2008 to 2019 were included. The proportion of 17-year- olds reporting depression during their lifetime, during the past year, or for the first time in the past year were determined for each year. Rates of depression remained similar from 2008 to 2012 (lifetime, 17%; current year, 11%; incident cases, 5%) followed by the onset of a significantly growing wave, almost doubling by 2019, reaching 30% (lifetime), 21% (current year) and 9% (incident cases). This wave shows that depression emerges before college for a high proportion of youth. Collegiate mental health must focus on this wave among arriving students, in addition to programs for the much smaller new incidence of depression that emerges during college. [ABSTRACT FROM AUTHOR]

Objective: Preclinical work suggests that excess glucocorticoids and reduced cortical γ-aminobutyric acid (GABA) may affect sex-dependent differences in brain regions implicated in stress regulation and depressive phenotypes. The authors sought to address a critical gap in knowledge, namely, how stress circuitry is functionally affected by glucocorticoids and GABA in current or remitted major depressive disorder (MDD). Methods: Multimodal imaging data were collected from 130 young adults (ages 18–25), of whom 44 had current MDD, 42 had remitted MDD, and 44 were healthy comparison subjects. GABA+ (γ-aminobutyric acid and macromolecules) was assessed using magnetic resonance spectroscopy, and task-related functional MRI data were collected under acute stress and analyzed using data-driven network modeling. Results: Across modalities, trait-related abnormalities emerged. Relative to healthy comparison subjects, both clinical groups were characterized by lower rostral anterior cingulate cortex (rACC) GABA+ and frontoparietal network amplitude but higher amplitude in salience and stress-related networks. For the remitted MDD group, differences from the healthy comparison group emerged in the context of elevated cortisol levels, whereas the MDD group had lower cortisol levels than the healthy comparison group. In the comparison group, frontoparietal and stress-related network connectivity was positively associated with cortisol level (highlighting putative top-down regulation of stress), but the opposite relationship emerged in the MDD and remitted MDD groups. Finally, rACC GABA+ was associated with stress-induced changes in connectivity between overlapping default mode and salience networks. Conclusions: Lifetime MDD was characterized by reduced rACC GABA+ as well as dysregulated cortisol-related interactions between top-down control (frontoparietal) and threat (task-related) networks. These findings warrant further investigation of the role of GABA in the vulnerability to and treatment of MDD. [ABSTRACT FROM AUTHOR]

Dysthymia, a persistent depressive disorder, manifests as a chronic state of depressed mood. Its prevalence in the general population is estimated to be around 1% to 2%, with a higher incidence in women compared to men. The utilisation of innovative psychological assessment tools like the Sentence Completion Test and Somatic Inkblot Test provides a nuanced understanding of an individual's perceptual and cognitive processes related to bodily sensations and emotional experiences. By integrating familial lens into the exploration of dysthymia and heightened fixation on unusual bodily sensations, this study endeavours to unravel the potential role and impact of family dynamics in shaping the experiences of individuals grappling with this intricate intersection. Mr. Y.C. is a 33 year old male, Graduate Engineer (B. Tech) and currently unemployed. His chief complaints were of sad mood, feelings of loneliness, lack of concentration, loss of pleasure in things he previously enjoyed, indecisiveness and uncomfortable body sensations such as stiffness in body and sensation of heat in certain parts of body. He reported having sexual relationships with several partners but not able to build an emotional attachment with anyone. The findings on assessments reveal parental conflict that contributes to his symptoms of dysthymia and heightened preoccupation with bodily sensations. Furthermore, his conflicted relationship with mother also reflects internalised aggression and frustration, which impacts his ability to maintain a healthy romantic relationship with any woman. The weekly therapy sessions spread over a period of 4 months have led to improvement in socio-occupational functioning as the patient is now working as an IIT coach in a coaching centre. Future interventions will focus on developing conflict resolution strategies and promote constructive ways to address and resolve family conflicts. [ABSTRACT FROM AUTHOR]

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

Background. Timely and accurately conducted introduction of demoralization into the differential diagnostics make it possible to define objective and subjective factors essential to demoralization, which constitute actual psychological state of a patient. It also helps to differentiate these factors from variety of syndrome signs and, therefore, to stabilize individual mental condition by making therapeutic interventions more targeted. Objectives. The aim is to elicit specific features of and to discern criteria for distinction of the notion of demoralization from variety of other concepts frequently used in clinical psychologist’s activity to describe pathological mental states that patients with severe somatic disease may have. Results. Based on the comparison of the demoralization concept and mental distortions frequent in a clinic of severely ill somatic patients, essential and pivotal sings of the phenomenon of demoralization are shown. The epidemiological data on occurrence and intensity rates, as well as demoralization comorbidity to a number of disturbed mental activity symptoms and states amid patients with different somatic nosology are given. Conclusions. As a psychological state, demoralization can be diagnosed among either inpatients or outpatients. It might also present itself singularly or be comorbid to any mental distortion yet maintaining its seminal qualities, such as distress, subjective incompetence experience and preservation of motivation. Discrimination of demoralization state might have both therapeutic and prognostic value.

Irritable bowel syndrome (IBS) is considered a stress disorder characterized by psychological and gastrointestinal dysfunction. IBS patients not only suffer from intestinal symptoms such as abdominal pain, diarrhea, or constipation but also, experience dysthymic disorders such as anxiety and depression. Studies have found that corticotropin-releasing hormone plays a key role in IBS with comorbid dysthymic disorders. Next, we will summarize the effects of corticotropin-releasing hormone from the central nervous system and periphery on IBS with comorbid dysthymic disorders and relevant treatments based on published literatures in recent years.

AbstractToday, melancholia is no longer used as a separate clinical picture in psychotherapeutic diagnostics. Instead, the symptoms are subsumed under major depression or dysthymia and understood as a disease concept. In both Freud's interpretation and in the artistic, Islamic, poetic, and medical-historical approaches in Turkish culture, melancholia is understood in a richer way than just in terms of a “disease-like disorder.” This article aims to emphasize the broader understanding of melancholia within the Turkish-Islamic context and illuminate intersections with psychoanalysis. Since the Islamic faith occupies an important place in the treatment and popular understanding of mental disorders both historically and to the present day, religious and mystical aspects related to melancholia are also considered in this article. A case vignette of a melancholic migrant woman with Turkish roots is used to trace the psychodynamic movements in her treatment. In order to follow this patient’s psychoanalytic process, the theoretical explanations in the first part of the article provide the sensibilization for a deeper understanding of the cultural and religious aspects important to the inner dynamics of this woman.

Background: Depressive disorders have been identified as a significant contributor to non-fatal health loss in China. Among the various subtypes of depressive disorders, dysthymia is gaining attention due to its similarity in clinical severity and disability to major depressive disorders (MDD). However, national epidemiological data on the burden of disease and risk factors of MDD and dysthymia in China are scarce. Methods: This study aimed to evaluate and compare the incidence, prevalence, and disability-adjusted life-years (DALYs) caused by MDD and dysthymia in China between 1990 and 2019. The temporal trends of the depressive disorder burden were evaluated using the average annual percentage change. The comparative risk assessment framework was used to estimate the proportion of DALYs attributed to risk factors, and a Bayesian age-period-cohort model was applied to project the burden of depressive disorders. Results: From 1990 to 2019, the overall age-standardized estimates of dysthymia in China remained stable, while MDD showed a decreasing trend. Since 2006, the raw prevalence of dysthymia exceeded that of MDD for the first time, and increased alternately with MDD in recent years. Moreover, while the prevalence and burden of MDD decreased in younger age groups, it increased in the aged population. In contrast, the prevalence and burden of dysthymia remained stable across different ages. In females, 11.34% of the DALYs attributable to depressive disorders in 2019 in China were caused by intimate partner violence, which has increasingly become prominent among older women. From 2020 to 2030, the age-standardized incidence, prevalence, and DALYs of dysthymia in China are projected to remain stable, while MDD is expected to continue declining. Conclusions: To reduce the burden of depressive disorders in China, more attention and targeted strategies are needed for dysthymia. It's also urgent to control potential risk factors like intimate partner violence and develop intervention strategies for older women. These efforts are crucial for improving mental health outcomes in China. [ABSTRACT FROM AUTHOR]

Background: Globally, infertility is known as a major problem which can ruin a couple's relationship. In recent years, many studies have addressed the causes of infertility, the outcomes of treatments for infertility, and the effects of infertility on couples' mental health; however, the concept of dignity of women living with infertility has never been examined in depth. Objective: This study aimed to explore the dignity of women living with infertility in Iran. Design: This qualitative research was conducted via conventional content analysis approach. Methods: This qualitative study was conducted in Iran from February to December 2022. In this research, the data were collected through face-to-face semi-structured in-depth interviews with 23 women living with infertility selected via purposive sampling. The interviews were continued until reaching the data saturation point. Data analysis was performed simultaneously with data collection. The interviews were recorded, transcribed, and analyzed through Graneheim and Lundman style content analysis, with data management done using the MAXQDA software. To achieve the accuracy and validity of the study, the four-dimension criteria by Lincoln and Guba, namely credibility, dependability, conformability, and transformability, were considered and used. Results: Analysis of the qualitative data yielded three themes and eight subthemes. The three main themes were (1) overcoming identity crises (overcoming dysthymia, coping with unaccomplished motherhood), (2) respect for personal identity (respect for confidentiality; respect for beliefs, values, and attitudes; avoidance of stigma and pity), and (3) compassion-focused therapy (sympathizing, mental and spiritual support, and enhancement of life skills). Conclusion: Dignity of women living with infertility encompasses overcoming identity crises, respect for personal identity, and compassion therapy. The policymakers and administrators in the healthcare system can use the findings of this study to create a proper clinical environment toward preserving the dignity of women living with infertility.

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

The dysregulation of pro- and anti-inflammatory processes in the brain has been linked to the pathogenesis of major depressive disorder (MDD), although the precise mechanisms remain unclear. In this study, we discovered that microglial conditional knockout of Pdcd4 conferred protection against LPS-induced hyperactivation of microglia and depressive-like behavior in mice. Mechanically, microglial Pdcd4 plays a role in promoting neuroinflammatory responses triggered by LPS by inhibiting Daxx-mediated PPARγ nucleus translocation, leading to the suppression of anti-inflammatory cytokine IL-10 expression. Finally, the antidepressant effect of microglial Pdcd4 knockout under LPS-challenged conditions was abolished by intracerebroventricular injection of the IL-10 neutralizing antibody IL-10Rα. Our study elucidates the distinct involvement of microglial Pdcd4 in neuroinflammation, suggesting its potential as a therapeutic target for neuroinflammation-related depression.

Background: This study evaluates longitudinal associations between glycaemic control, measured by mean and within-patient variability of glycated haemaglobin (HbA1c) levels, and major depressive disorder (MDD) in individuals with type 2 diabetes (T2D), focusing on the timings of these diagnoses. Methods: In UK Biobank, T2D was defined using self-report and linked health outcome data, then validated using polygenic scores. Repeated HbA1c measurements (mmol/mol) over the 10 years following T2D diagnosis were outcomes in mixed effects models, with disease duration included using restricted cubic splines. Four MDD exposures were considered: MDD diagnosis prior to T2D diagnosis (pre-T2D MDD), time between pre-T2D MDD diagnosis and T2D, new MDD diagnosis during follow-up (post-T2D MDD) and time since post-T2D MDD diagnosis. Models with and without covariate adjustment were considered. Results: T2D diagnostic criteria were robustly associated with T2D polygenic scores. In 11,837 T2D cases (6.9 years median follow-up), pre-T2D MDD was associated with a 0.92 increase in HbA1c (95% CI: [0.00, 1.84]), but earlier pre-T2D MDD diagnosis correlated with lower HbA1c. These pre-T2D MDD effects became non-significant after covariate adjustment. Post-T2D MDD individuals demonstrated increasing HbA1c with years since MDD diagnosis ( β = 0.51 , 95% CI: [0.17, 0.86]). Retrospectively, across study follow-up, within-patient variability in HbA1c was 1.16 (95% CI: 1.13–1.19) times higher in post-T2D MDD individuals. Conclusions: The timing of MDD diagnosis is important for understanding glycaemic control in T2D. Poorer control was observed in MDD diagnosed post-T2D, highlighting the importance of depression screening in T2D, and closer monitoring for individuals who develop MDD after T2D.

Although various algorithms and strategies have been proposed for predicting depression and anxiety, none of the work is still suggested for an automated system for an early assessment of Dysthymia. This study aimed to enhance the accuracy of early diagnosis for Persistent Depression Disorder (PDD) through an improved machine learning technique utilizing the stacking SVM ensemble approach. To expedite the initial screening of dysthymia in students, a quantitative analysis of behavioral data based on machine learning was employed. The research collected behavioral data from 137 college students, and the gathered data was used for model development and experimentation. The findings revealed that PDD was predominantly prevalent among middle-class undergraduates majoring in non-technical fields. Notably, PDD rates were higher among rural undergraduates from both high- and low-income backgrounds. The proposed stacked SVM model demonstrated superior performance, achieving an accuracy of 89.4%. Detecting PDD early among undergraduates is crucial for mental health professionals, and the stacked SVM method proved effective in this aspect. [ABSTRACT FROM AUTHOR]

Background: To explore the demographic and clinical features of current depressive episode that discriminate patients diagnosed with major depressive disorder (MDD) from those with bipolar I (BP-I) and bipolar II (BP-II) disorder who were misdiagnosed as having MDD. Methods: The Mini-International Neuropsychiatric Interview (MINI) assessment was performed to establish DSM-IV diagnoses of MDD, and BP-I and BP-II, previously being misdiagnosed as MDD. Demographics, depressive symptoms and psychiatric comorbidities were compared between 1463 patients with BP-I, BP-II and MDD from 8 psychiatric settings in mainland China. A multinomial logistic regression model was performed to assess clinical correlates of diagnoses. Results: A total of 14.5% of the enrolled patients initially diagnosed with MDD were eventually diagnosed with BP. Broad illness characteristics including younger age, higher prevalence of recurrence, concurrent dysthymia, suicidal attempts, agitation, psychotic features and psychiatric comorbidities, as well as lower prevalence of insomnia, weight loss and somatic symptoms were featured by patients with BP-I and/or BP-I, compared to those with MDD. Comparisons between BP-I and BP-II versus MDD indicated distinct symptom profiles and comorbidity patterns with more differences being observed between BP-II and MDD, than between BP-I and MDD. Conclusion: The results provide evidence of clinically distinguishing characteristics between misdiagnosed BP-I and BP- II versus MDD. The findings have implications for guiding more accurate diagnoses of bipolar disorders. [ABSTRACT FROM AUTHOR]

Purpose: Depressive disorders cause a major burden of disease worldwide and often lead to a loss of social functioning. Patients suffering from depressive disorders report a lower quality of life (QOL) than people without a history of mental health issues. Internet-based interventions (IBIs) based on cognitive behavioral therapy (CBT) are effective in reducing symptom severity but data on their impact on quality of life in clinically depressed patients so far is scarce. Methods: Selfapy is a CBT-based IBI for depressive disorders. 401 participants (332 female, mean age 37 (SD = 11) with a diagnosis of major depressive disorder (MDD) or dysthymia were enrolled in a randomized, parallel, three-arm trial comparing a therapist-guided Selfapy intervention with an unguided Selfapy intervention and a waiting list control. QOL was measured using the WHOQOL-BREF at baseline, post-treatment (12 weeks) and at 24-week follow-up. The effects of the interventions on QOL were calculated using linear mixed effects models. Results: At post-treatment (12 weeks) the guided and unguided intervention groups reported an increase in QOL on physical and psychological health domains compared to controls (significant group*time interaction). The gain in QOL was maintained over the follow-up period only for psychological health. QOL decreased in the social relationships and environment domains over the course of treatment and during the follow-up treatment for all participants. There were no differences between the guided and the unguided intervention. Conclusion: Selfapy proved to positively affect psychological and physical QOL in a sample of participants suffering from depressive disorders and can therefore be considered an effective and highly scalable therapeutic tool. The pattern of results might partly be attributable to effects of the COVID-19 pandemic and public health measures that coincided with the trial.

• Immune-inflammatory mechanisms are promising targets for antidepressant pharmacology. • In a randomized controlled trial low-dose IL-2 significantly improved antidepressant response. • IL-2 rapidly expanded the population of Treg, Th2, and Naive CD4+/CD8 + immune cell counts. • Strengthening in the T cell system predicted antidepressant response. Immune-inflammatory mechanisms are promising targets for antidepressant pharmacology. Immune cell abnormalities have been reported in mood disorders showing a partial T cell defect. Following this line of reasoning we defined an antidepressant potentiation treatment with add-on low-dose interleukin 2 (IL-2). IL-2 is a T-cell growth factor which has proven anti-inflammatory efficacy in autoimmune conditions, increasing thymic production of naïve CD4 + T cells, and possibly correcting the partial T cell defect observed in mood disorders. We performed a single-center, randomised, double-blind, placebo-controlled phase II trial evaluating the safety, clinical efficacy and biological responses of low-dose IL-2 in depressed patients with major depressive (MDD) or bipolar disorder (BD). 36 consecutively recruited inpatients at the Mood Disorder Unit were randomised in a 2:1 ratio to receive either aldesleukin (12 MDD and 12 BD) or placebo (6 MDD and 6 BD). Active treatment significantly potentiated antidepressant response to ongoing SSRI/SNRI treatment in both diagnostic groups, and expanded the population of T regulatory, T helper 2, and percentage of Naive CD4+/CD8 + immune cells. Changes in cell frequences were rapidly induced in the first five days of treatment, and predicted the later improvement of depression severity. No serious adverse effect was observed. This is the first randomised control trial (RCT) evidence supporting the hypothesis that treatment to strengthen the T cell system could be a successful way to correct the immuno-inflammatory abnormalities associated with mood disorders, and potentiate antidepressant response.

Objectives: The caecum bridges the small and large intestine and plays a front‐line role in discriminating gastrointestinal antigens. Although dysregulated in acute and chronic conditions, the tissue is often overlooked immunologically. Methods: To address this issue, we applied single‐cell transcriptomic‐V(D)J sequencing to FACS‐isolated CD45+ caecal patch/lamina propria leukocytes from a healthy (5‐year‐old) female rhesus macaque ex vivo and coupled these data to VDJ deep sequencing reads from haematopoietic tissues. Results: We found caecal NK cells and ILC3s to co‐exist with a spectrum of effector T cells partially derived from SOX4+ recent thymic emigrants. Tolerogenic Vγ8Vδ1‐T cells, plastic CD4+ T helper cells and GZMK+EOMES+ and TMIGD2+ tissue‐resident memory CD8+ T cells were present and differed metabolically. An IL13+GATA3+ Th2 subset expressing eicosanoid pathway enzymes was accompanied by IL1RL1+GATA3+ regulatory T cells and a minor proportion of IgE+ plasma cells (PCs), illustrating tightly regulated type 2 immunity devoid of ILC2s. In terms of B lymphocyte lineages, caecal patch antigen‐presenting memory B cells sat alongside germinal centre cells undergoing somatic hypermutation and differentiation into IGF1+ PCs. Prototypic gene expression signatures decreased across PC clusters, and notably, expanded IgA clonotypes could be traced in VDJ deep sequencing reads from additional compartments, including the bone marrow, supporting that these cells contribute a steady stream of systemic antibodies. Conclusions: The data advance our understanding of caecal immunological function, revealing processes involved in barrier maintenance and molecular networks relevant to disease.

Purpose: Depressive disorder is a mental health disorder with complicated etiopathogenesis. Environmental stress and neurodevelopment combined with other factors contribute to the occurrence of depression. Especially for the depressive disorder with chronic negative stress, it has characteristics of recurrence and poor curative effect because of unclear mechanism. Here, we investigated the hippocampal structures and functional connectivity (FC) according to resting-state functional magnetic resonance imaging in patients with depression who underwent chronic negative stress. Patients and Methods: A total of 65 patients with depression (34 underwent chronic negative stress and 31 non-underwent chronic negative stress) and 30 healthy controls who did not undergo chronic negative stress were included in the study. The volumes of hippocampal subfields, seed-based FCs between hippocampus and the whole brain voxels, and ROI-wise-based FC between hippocampal subfields were compared among the three groups. Results: In the patients with depression who underwent chronic negative stress, the volumes of right_GC-ML-DG-head, right_CA4-head and right_CA3-head increased, FCs between Temporal_Mid_R, Precuneus_R, Frontal_Sup_R, Temporal_Sup_R, Angular_L, Frontal_Inf_Tri_R, Supp_Motor_Area_R, Precentral_L and hippocampus increased, and FCs between parasubiculum and CA3, and presubiculum and CA1 decreased. When compared to the patients who did not undergo chronic negative stress, the patients who underwent chronic negative stress had larger volumes of right_GC-ML-DG-head and right_CA3-head, higher FCs between Frontal_Sup_R, Frontal_Inf_Tri_R and hippocampus, and lower FCs between presubiculum and CA1. Conclusion: The depression underwent chronic negative stress may experience disrupted hippocampal structures and functional connectivity. It may be one of potential depressive disorder subtypes.

Neuropsychiatric disorders denote a broad range of illnesses involving neurology and psychiatry. These disorders include depressive disorders, anxiety, schizophrenia, bipolar disorder, attention deficit hyperactivity disorder, autism spectrum disorders, headaches, and epilepsy. In addition to their main neuropathology that lies in the central nervous system (CNS), lately, studies have highlighted the role of immunity and neuroinflammation in neuropsychiatric disorders. Toll‐like receptors (TLRs) are innate receptors that act as a bridge between the innate and adaptive immune systems via adaptor proteins (e.g., MYD88) and downstream elements; TLRs are classified into 13 families that are involved in normal function and illnesses of the CNS. TLRs expression affects the course of neuropsychiatric disorders, and is influenced during their pharmacotherapy; For example, the expression of multiple TLRs is normalized during the major depressive disorder pharmacotherapy. Here, the role of TLRs in neuroimmunology, treatment, and management of neuropsychiatric disorders is discussed. We recommend longitudinal studies to comparatively assess the cell‐type‐specific expression of TLRs during treatment, illness progression, and remission. Also, further research should explore molecular insights into TLRs regulation and related pathways. [ABSTRACT FROM AUTHOR]

Irritable bowel syndrome (IBS) is considered a stress disorder characterized by psychological and gastrointestinal dysfunction. IBS patients not only suffer from intestinal symptoms such as abdominal pain, diarrhea, or constipation but also, experience dysthymic disorders such as anxiety and depression. Studies have found that corticotropin-releasing hormone plays a key role in IBS with comorbid dysthymic disorders. Next, we will summarize the effects of corticotropinreleasing hormone from the central nervous system and periphery on IBS with comorbid dysthymic disorders and relevant treatments based on published literatures in recent years.

Background: Lithium stands as the gold standard in treating bipolar disorders (BD). Despite numerous clinical factors being associated with a favorable response to lithium, comprehensive studies examining the collective influence of clinical variables alongside psychopathological dimensions are lacking. Our study aims to enhance comprehension of lithium response in individuals with BD by integrating clinical variables with psychopathological traits and early adverse events. Methods: We assessed 201 patients with BD for clinical characteristics, childhood trauma, temperament traits, impulsivity, and aggression. Lithium response was evaluated using the gold standard Alda scale, and predictors of lithium response were estimated through a multivariate model. Results: On the total sample, 61 (30.3%) patients were lithium responders according to the Alda scale. Comparatively, lithium responders, in contrast to non-responders, demonstrated a higher prevalence of the mania-depression-interval (MDI) cycle, a more frequent diagnosis of BD type I, and reported an earlier age of onset. They also exhibited less lifetime substance abuse, emotional, physical, and sexual abuse, while scoring higher on hyperthymic and irritable temperament scales. In multivariate analyses, only the MDI cycle (OR,3.47; 95%CI,1.61–7.50) hyperthymic (OR,1.20; 95%CI,1.02–1.41) and irritable temperament (OR,1.28; 95%CI,1.08–1.52) persisted as significant predictors of a positive response to lithium treatment, while emotional (OR,0.87; 95%CI,0.76–0.98) and physical abuse (OR,0.83; 95%CI,0.70–0.98) were predictors of non-response. Conclusions: In evaluating lithium response in BD, our study highlights the importance of considering clinical variables alongside temperament and childhood adversities. The assessment of hyperthymic and irritable temperament, emotional and physical abuse together with the type of cycle is of particular importance. Furthermore, our findings underscore the significance of systematically assessing the type of cycle in patients with BD through the use of life charts. [ABSTRACT FROM AUTHOR]

Objective: To determine the association between diabetes mellitus and chronic depression in adults in the Peruvian population. Materials and methods: A quantitative, observational, cross-sectional and correlational study was carried out, based on the data collected by the 2020 Encuesta Demográfica y de Salud Familiar (ENDES - Demographic and Family Health Survey, 2020). The sample was made up of 14,245 adults; depression was considered as a dependent variable (with depression/without depression), and the independent variables were diabetes mellitus (Yes/No), wealth index (the poorest, poor, middle class, rich, the richest), education (kindergarten-preschool and primary, secondary, non-university higher, university higher and graduate), alcoholism (Yes/No), area of residence (urban/rural). The program used for the statistical analysis was IBM SPSS: Release 23. A univariate data analysis was carried out by determining the frequencies and percentages. Subsequently, in the analytical phase, bivariate and multivariate analyses by logistic regression were used to evaluate the strength of the association between the variables (p < 0.05). Results: A total of 15.7 % of adults between 27 and 59 years of age experienced chronic depression. Furthermore, the bivariate analysis revealed an association between the outcome variable and covariates-diabetes mellitus, level of education and wealth index-(p < 0.05). Depression is more common in lower socioeconomic groups, with higher rates among the poor (16.63 %) and less educated population, especially in those with kindergarten, preschool and primary education (18.88 %). In contrast, the rich and richest classes show lower rates of depression (15.27 % and 12.04 %, respectively). On the other hand, in the multivariate analysis, the risk estimation was carried out, and it was found that having diabetes increased the risk of suffering depression by 1.66 times compared to patients who did not have diabetes. Conclusions: There is an association between chronic depression and diabetes mellitus in the adult population aged 27 to 59 years; in addition, a low wealth index and a lower level of education are risk factors for chronic depressive disorder.

The binary major depressive disorder (MDD) diagnosis is inadequate and should never be used in research. The study's objective is to explicate our novel precision nomothetic strategy for constructing depression models based on adverse childhood experiences (ACEs), lifetime and current phenome, and biomarker (atherogenicity indices) scores. This study assessed recurrence of illness (ROI: namely recurrence of depressive episodes and suicidal behaviors, SBs), lifetime and current SBs and the phenome of depression, neuroticism, dysthymia, anxiety disorders, and lipid biomarkers including apolipoprotein (Apo)A, ApoB, free cholesterol and cholesteryl esters, triglycerides, high density lipoprotein cholesterol in 67 normal controls and 66 MDD patients. We computed atherogenic and reverse cholesterol transport indices. We were able to extract one factor from a) the lifetime phenome of depression comprising ROI, and traits such as neuroticism, dysthymia and anxiety disorders, and b) the phenome of the acute phase (based on depression, anxiety and quality of life scores). PLS analysis showed that 55.7 % of the variance in the lifetime + current phenome factor was explained by increased atherogenicity, neglect and sexual abuse, while atherogenicity partially mediated the effects of neglect. Cluster analysis generated a cluster of patients with major dysmood disorder, which was externally validated by increased atherogenicity and characterized by increased scores of all clinical features. The outcome of depression should not be represented as a binary variable (MDD or not), but rather as multiple dimensional scores based on biomarkers, ROI, subclinical depression traits, and lifetime and current phenome scores including SBs. • Depression should not be represented as a binary variable, but rather as multiple continuous scores. • These continuous scores include recurrence of illness, suicidal behaviors, and the phenome. • We show how to build nomothetic models that include biomarkers and adverse childhood experiences. • These continuous scores are designated as Research and Diagnostic Algorithmic Rules (RADAR). • These RADAR scores can be integrated into a RADAR graph, a personalized fingerprint of the patient.

Immunogenicity of SARS-CoV-2 mRNA vaccines is highly heterogeneous in patients with inborn errors of immunity (IEIs). This case report analyzes the immune response to mRNA COVID-19 two-dose primary vaccination followed by three boosters in an IEI patient with marked CD4+ T-cell cytopenia and diminished thymic output, in comparison with that raised against latent, chronic cytomegalovirus (CMV) infection. Serum IgG antibodies anti-spike (S) protein of SARS-CoV-2 and anti-CMV were both determined by chemiluminescent microparticle immunoassays (CMIAs). SARS-CoV-2 and CMV memory CD4+ T-cell responses were simultaneously evaluated in vitro using an activation-induced marker (AIM) assay via multicolor flow cytometry. Throughout the 2-year follow-up that included the administration of five doses of SARS-CoV-2 mRNA vaccines, cellular anti-SARS-CoV-2-specific responses remained consistently negative, with extremely weak humoral responses, while the patient showed in vitro persistent CD4+ T-cell reactivity to CMV peptides and high-IgG CMV-specific titers. The assessment of immune responses to vaccines and prevalent viruses is essential in IEI patients in order to take adequate preventive measures. [ABSTRACT FROM AUTHOR]

While depression has been associated with alterations in the hypothalamic-pituitary adrenal (HPA) axis function, there is still controversy regarding the nature and extent of the dysfunction, such as in the debate about hypercortisolism vs. hypocortisolism. It may therefore be necessary to understand whether and how HPA axis function in depression is linked to mRNA expression of key genes regulating this system. We studied 163 depressed outpatients, most of whom were chronically ill, and 181 healthy controls. Blood mRNA expression levels of NR3C1 (including GRα , GRβ , and GR-P isoforms), FKBP4 , and FKBP5 were measured at baseline. HPA axis feedback sensitivity was measured by the dexamethasone (Dex)/corticotropin-releasing hormone (CRH) test. The association between mRNA expression levels and HPA axis feedback sensitivity was examined. Compared to controls, patients showed significantly higher expression of GRα and lower expression of FKBP5 , and higher post-Dex cortisol levels, even after controlling for age and sex. FKBP5 expression was significantly positively correlated with cortisol levels in patients, while GRα expression was significantly negatively correlated with cortisol levels in controls. Most patients were taking psychotropic medications. The large number of correlation tests may have caused type I errors. The tripartite relationship between depression, mRNA expression of GR and FKBP5 , and HPA axis function suggests that the altered gene expression affects HPA axis dysregulation and, as a result, impacts the development and/or illness course of depressive disorder. The combination of increased GRα expression and decreased FKBP5 expression may serve as a biomarker for chronic depression. • We examined blood mRNA expression of GR isoforms and FKBP4 / FKBP5 in depression. • Compared to controls, patients showed higher GRα and lower FKBP5 expression levels. • Compared to controls, patients had higher post-dexamethasone cortisol levels. • The differential gene expression was linked to altered HPA axis feedback sensitivity. • Gene expression affects HPA axis function, thereby possibly impacting depression.

Recent studies showed that immunometabolic dysregulation is related to unipolar major depressive disorder (MDD) and that it more consistently maps to MDD patients endorsing an atypical symptom profile, characterized by energy-related symptoms including increased appetite, weight gain, and hypersomnia. Despite the documented influence of the microbiome on immune regulation and energy homeostasis, studies have not yet investigated microbiome differences among clinical groups in individuals with MDD. Fifteen MDD patients with atypical features according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5)-5, forty-four MDD patients not fulfilling the DSM-5 criteria for the atypical subtype, and nineteen healthy controls were included in the study. Participants completed detailed clinical assessment and stool samples were collected. Samples were sequenced for the prokaryotic 16S rRNA gene, in the V3-V4 variable regions. Only samples with no antibiotic exposure in the previous 12 months and a minimum of >2000 quality-filtered reads were included in the analyses. There were no statistically significant differences in alpha- and beta-diversity between the MDD groups and healthy controls. However, within the atypical MDD group, there was an increase in the Verrucomicrobiota phylum, with Akkermansia as the predominant bacterial genus. Cross-sectional data, modest sample size, and significantly increased body mass index in the atypical MDD group. There were no overall differences among the investigated groups. However, differences were found at several taxonomic levels. Studies in larger longitudinal samples with relevant confounders are needed to advance the understanding of the microbial influences on the clinical heterogeneity of depression. • Human microbiome affects immunometabolism that connects to atypical depressive symptoms. • We explored microbiome across atypical vs. typical vs. healthy controls. • Depressive subtypes and the healthy controls do not differ across alpha and beta diversity. • Distinct taxonomic differences were present within individuals with atypical depression.

Immune responses to both SARS-CoV-2 infection and its associated vaccines have been highly variable within the general population. The increasing evidence of long-lasting symptoms after resolution of infection, called post-acute sequelae of COVID-19 (PASC) or "Long COVID," suggests that immunemediated mechanisms are at play. Closely related endemic common human coronaviruses (hCoV) can induce pre-existing and potentially cross-reactive immunity, which can then affect primary SARS-CoV-2 infection, as well as vaccination responses. The influence of pre-existing immunity from these hCoVs, as well as responses generated from original CoV2 strains or vaccines on the development of new high-affinity responses to CoV2 antigenic viral variants, needs to be better understood given the need for continuous vaccine adaptation and application in the population. Due in part to thymic involution, normal aging is associated with reduced naïve T cell compartments and impaired primary antigen responsiveness, resulting in a reliance on the pre-existing crossreactive memory cell pool which may be of lower affinity, restricted in diversity, or of shorter duration. These effects can also be mediated by the presence of down-regulatory anti-idiotype responses which also increase in aging. Given the tremendous heterogeneity of clinical data, utilization of preclinical models offers the greatest ability to assess immune responses under a controlled setting. These models should now involve prior antigen/viral exposure combined with incorporation of modifying factors such as age on immune responses and effects. This will also allow for mechanistic dissection and understanding of the different immune pathways involved in both SARS-CoV-2 pathogen and potential vaccine responses over time and how pre-existing memory responses, including potential anti-idiotype responses, can affect efficacy as well as potential off-target effects in different tissues as well as modeling PASC.

Purpose: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is characterized by a multiform clinical presentation requiring a differentiated treatment based on different phenotypes including the psychosocial and sexual domains. The aim of this study was assessing the complex correlations between somatic, psychological, and sexual symptoms of CP/CPPS patients. Materials and methods: We performed a cross-sectional study on patients attending a Prostatitis Clinic. Patients were administered the following questionnaires: National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF), Premature Ejaculation Diagnostic Tool (PEDT), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder 7-item (GAD-7), Oxford Happiness Questionnaire (OHQ), and Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire (TEMPS-A). Results: Linear regression analyses show highly significant correlations between scores of the NIH-CPSI and the scores of the GAD-7, PHQ-9 and OHQ psychometric questionnaires. IPSS scores correlate significantly with the psychometric scores only when a non-parametric analysis is performed. IIEF and PEDT sexual function scores did not correlate with any of the psychometric tests. NIH-CPSI scores correlate positively with most of the TEMPS-A profiles but the hyperthymic profile correlated negatively with the total and QoL NIH-CPSI and with PEDT scores. Conclusions: Scores measuring anxiety, depression, and psychological well-being in patients with CP/CPPS are strictly correlated with prostatitis-like symptoms although they are poorly correlated with symptoms of prostatism, as measured by IPSS, and not correlated with scores of sexual dysfunctions, as measured by IIEF and PEDT. A hyperthymic temperament may temperament may increase resilience against the disease. [ABSTRACT FROM AUTHOR]

Major depressive disorder (MDD) is a prevalent mental health condition with significant societal impact. Owing to the intricate biological diversity of MDD, treatment efficacy remains limited. Immune biomarkers have emerged as potential predictors of treatment response, underscoring the interaction between the immune system and the brain. This study investigated the relationship between cytokine levels and cortical thickness in patients with MDD, focusing on the corticolimbic circuit, to elucidate the influence of neuroinflammation on structural brain changes and contribute to a deeper understanding of the pathophysiology of MDD. A total of 114 patients with MDD and 101 healthy controls (HC) matched for age, sex, and body mass index (BMI) were recruited. All participants were assessed for depression severity using the Hamilton Depression Rating Scale (HDRS), and 3.0 T T1 weighted brain MRI data were acquired. Additionally, cytokine levels were measured using a highly sensitive bead-based multiplex immunosorbent assay. Patients diagnosed with MDD exhibited notably elevated levels of interleukin-6 (p = 0.005) and interleukin-8 (p = 0.005), alongside significant cortical thinning in the left anterior cingulate gyrus and left superior frontal gyrus, with these findings maintaining significance even after applying Bonferroni correction. Furthermore, increased interleukin-6 and interleukin-8 levels in patients with MDD are associated with alterations in the left frontomarginal gyrus and right anterior cingulate cortex (ACC). This suggests a potential influence of neuroinflammation on right ACC function in MDD patients, warranting longitudinal research to explore interleukin-6 and interleukin-8 mediated neurotoxicity in MDD vulnerability and brain morphology changes. • The study is one of the few that provides a potential link between neuroinflammation and structural alterations in the brain, enabling a novel insight on the pathophysiology of MDD. • Immune dysregulation in interleukin-6 (IL-6) and interleukin-8 (IL-8) were observed in patients with MDD compared with healthy individuals. • Significant cortical thinning was observed in patients with MDD in the left anterior cingulate gyrus and left superior frontal gyrus.

The co-occurrence of depression with cannabis use worsens both mood and substance use disorder outcomes, with young adults particularly at risk of co-occurrence. This research investigates whether the association of state-level prevalence rates of young adult (age 18–25) depression and cannabis use in the U.S. changed following enactment of recreational (adult use) cannabis legalization between 2008 and 2019. Annual, state prevalence data on past-year major depressive episode (hereafter, depression) and past-month cannabis use were extracted from the National Survey on Drug Use and Health (N =600 state-year observations). Moderated regression models tested whether the association of depression with cannabis use differed before versus after recreational legalization by comparing prevalence rates of depression and cannabis use in states that enacted recreational legalization to those that did not, while fixing state, year, and medical legalization effects. Data were accessed and analyzed in 2023. Prevalence rates of both depression and cannabis use increased throughout the study period. The positive statistical effect of depression on cannabis use more than doubled in magnitude after legalization (β=0.564, 95% CI=0.291, 0.838) as compared to before (β=0.229, 95% CI=0.049, 0.409), representing a significant change (β=0.335, 95% CI=0.093, 0.577). These results suggest that the association between prevalence rates of young adult depression and cannabis use strengthened following recreational legalization in the U.S. This is potentially due to increases in cannabis accessibility and the acceptance of the health benefits of cannabis, which may enhance the use of cannabis as a coping mechanism among young adults with depression.

Suicide was the main source of death from external causes in Spain in 2020, with 3,941 cases. The importance of identifying those mental disorders that influenced hospital readmissions will allow us to manage the health care of suicidal behavior. The feature selection of each hospital in this region was carried out by applying Machine learning (ML) and traditional statistical methods. The results of the characteristics that best explain the readmissions of each hospital after assessment by the psychiatry specialist are presented. Adjustment disorder, alcohol abuse, depressive syndrome, personality disorder, and dysthymic disorder were selected for this region. The most influential methods or characteristics associated with suicide were benzodiazepine poisoning, suicidal ideation, medication poisoning, antipsychotic poisoning, and suicide and/or self-harm by jumping. Suicidal behavior is a concern in our society, so the results are relevant for hospital management and decision-making for its prevention. [ABSTRACT FROM AUTHOR]
