Anger attacks in depression--evidence for a male depressive syndrome

Mapping the 5-HTergic neural pathways in perimenopausal mice and elucidating the role of oestrogen receptors in 5-HT neurotransmission

Perimenopausal syndrome (PMS) encompasses neuropsychiatric symptoms, such as hot flashes and depression, which are associated with alterations in the 5-HTergic neural pathway in the brain. However, the specific changes and mechanisms underlying these alterations remain unclear. In this study, ovariectomized mice were used to successfully establish a perimenopause model, and the changes in the expression of 5-HT and its receptors (5-HT1AR and 5-HT2AR) across 72 brain regions in these ovariectomized mice were assessed by immunohistochemistry. Although both 5-HT and 5-HT1AR were widely expressed throughout the brain, only a limited number of regions expressed 5-HT2AR. Notably, decreased expression of 5-HT was observed across almost all brain regions in the ovariectomy (OVX) group compared with the Sham group. Altered expression of both receptors was found within areas related to hot flashes (the preoptic area) or mood disorders (the amygdala). Additionally, reduced oestrogen receptor (ER)α/β expression was detected in cells in the raphe nucleus (RN), an area known to regulate body temperature. Results showed that ERα/β positively regulate the transcriptional activity of the enzymes TPH2/MAOA, which are involved in serotonin metabolism during perimenopause. This study revealed the changes in 5-HT neuropathways (5-HT, 5-HT1AR and 5-HT2AR) in perimenopausal mice, mainly in brain regions related to regulation of the body temperature, mood, sleep and memory. This study clarified that the expression of oestrogen receptor decreased in perimenopause, which regulated the transcription levels of TPH2 and MAOA, and ultimately led to the reduction of 5-HT content, providing a new target for clinical diagnosis and treatment of perimenopausal diseases.

Depressive symptoms and anger and aggression in Russian adolescents

Research among adolescents exploring the association between depressive symptoms and aggression has produced inconsistent findings. This study investigated the prevalence of clinically significant (current major depressive episode) and subthreshold depressive symptoms in a general population sample of adolescents from Northern Russia and explored their association with aggression and anger, while controlling for comorbid mental health problems. The sample consisted of 2600 participants, aged 13-17 years (59.5% female; 95.7% ethnic Russian). Symptoms of a current major depressive episode, types of anger and aggression (anger rumination, trait anger, physical, verbal and social aggression) and comorbid problems (posttraumatic stress, alcohol use, anxiety, and hyperactivity/impulsivity) were assessed by means of self-reports. The prevalence of a clinically significant depressive episode in the past month was 3.5%, while for subthreshold depression it was 21.6%. All anger and aggression variables, as well as comorbid problems increased together with increasing levels of depression. The association between overt aggressive behavior and depression was primarily explained by comorbid mental health problems, whereas anger rumination and social aggression had more direct associations with depression, independent of comorbidity. Among adolescents with depression, boys reported higher levels of social and verbal aggression and of anger rumination than girls. The results of this study suggest that interventions aiming to reduce aggressive behavior in adolescents should consider depression and its comorbid conditions.

Development and verification of the Menopause Emotional Symptom Questionnaire

OBJECTIVE

A detailed, well-validated scale for measuring emotional symptoms in menopausal women is lacking. We aimed to develop the Menopause Emotional Symptom Questionnaire (MESQ) and to confirm its reliability and validity among Koreans.

METHODS

Eighteen primary items based on previous research results were selected using exploratory factor analysis and confirmatory factor analysis (CFA). New data, including answers to the novel MESQ, Menopause Rating Scale, Kupperman Index, Beck Depression Inventory-II, and Beck Anxiety Inventory, were collected from 200 perimenopausal women and 100 young men through a research company. Exploratory factor analysis and CFA were performed again to determine whether the MESQ accurately measures emotional symptoms in perimenopausal women. Receiver operating characteristic curve and k-means cluster analyses were used to identify the most appropriate cutoff value.

RESULTS

The MESQ showed high internal consistency (Cronbach α = 0.926), and the CFA revealed that the factor structure comprised two subscales: nine items for mood/anxiety symptoms and four items for sleep symptoms. A high correlation between the total MESQ score and total scores of the existing scales was confirmed, indicating high convergence validity. Comparison of the mean MESQ scores between men and women showed significant sex difference, indicating secure known-group validity. The cutoff point of the total MESQ score between the high-risk and low-risk groups was 26.

CONCLUSIONS

The novel MESQ has high validity and reliability, and this study confirmed that the MESQ is a valid tool for screening for and measuring emotional symptoms in menopausal women in Korea.

Evaluation of a male-specific psychotherapeutic program for major depressive disorder compared to cognitive behavioral therapy and waitlist: study protocol for a six-arm randomized clinical superiority trial examining depressed eugonadal and hypogonadal men receiving testosterone

Background

Treatment of major depressive disorder (MDD) in men is complicated by the endorsement of traditional masculinity ideologies (TMI) often leading to reluctance toward psychotherapy, therapy interfering processes, or premature termination. In addition, it has been shown that men with MDD have a significantly increased risk of being hypogonadal (e.g., total testosterone levels <12.1 nmoL/L). Therefore, it is recommended to examine depressed men with regard to their testosterone status and if hypogonadism is present to combine psychotherapy with testosterone treatment (TT).

Aim

This project aims to evaluate a male-specific psychotherapeutic program (MSPP) for MDD in depressed eugonadal and hypogonadal men receiving testosterone in comparison to a standard cognitive behavioral therapy (CBT) for MDD and a Waitlist.

Methods

The study presents a 2×3 factorial study design. In total, 144 men aged between 25 and 50 will be stratified by testosterone status (eugonadal/hypogonadal) and then randomized into one of the three conditions (MSPP, CBT, or Waitlist). Additionally, a healthy control group of 100 men will be recruited, which will undergo only baseline assessments. Both standardized psychotherapy programs will encompass 18 sessions delivered in a weekly manner. Aligned with the TT-related medical visits of the 72 hypogonadal men, all participants will be followed up with clinical assessments and bio sampling at weeks 0, 6, 15, 24, and 36.

Expected results

Compared to Waitlist control groups, treatment groups are expected to be more effective and efficacious (depression score reduction of ≥50%) at week 24 and at the follow-up at week 36. The MSPP is expected to show higher effectiveness and efficacy for depressive symptoms and higher acceptability (lower dropout rate) as compared to CBT.

Discussion

This study represents the first attempt to test a male-specific psychotherapy for MDD in a single-setting compared to standard CBT and a Waitlist control condition using randomized clinical trial methodology. In addition, the potential positive adjunct effect of psychotherapy to TT in reducing depressive burden and improving quality of life in hypogonadal depressed men represents a neglected research area and might introduce new hypogonadism screening procedures in depressed men and combined treatment approaches for depressed men suffering from hypogonadism. Limitations are the rigorous inclusion and exclusion criteria, which limit the generalizability of the study results to first episode treatment naïve depressed men.

Gender Differences in the Psychopathology of Mixed Depression in Adolescents with a Major Depressive Episode

BACKGROUND

Gender differences have been reported in the severity and psychopathological features of major depressive disorders among adults but are poorly reported in adolescent samples.

OBJECTIVE

This study aimed to examine gender differences in the psychopathology of mixed depression among adolescents.

METHODS

We analyzed 341 outpatients with the current major depressive episode (MDE) retrospectively to identify patients with DSM-5 MDE with mixed features. We compared examiner-rated depressive and (hypo)manic symptoms and self- and parent-reported symptoms between sexes.

RESULTS

We identified 76 patients with an MDE with mixed features (67.1% females, 32.9% with bipolar disorder). Depression severity was significantly greater in females versus males (CDRS-R total score 56.2 vs. 48.2, p = 0.014). Depressive symptoms were significantly and independently found to be more severe among females in a logistic regression model, including excessive fatigue (OR 1.68; p = 0.025), low self-esteem (OR 1.67; p = 0.04), excessive weeping (OR 1.62; p = 0.021), and CBCL AAA index (OR 1.04; p = 0.015). None of the depressive symptoms scored greater in males. Males had higher levels of motor activity (2.12 vs. 1.69; p = 0.048) and pressured speech (1.80 vs. 1.24; p = 0.004). Self-rated anxiety (69.3 vs. 56.8, p = 0.047) and CBCL AAA index (207 vs. 189; p = 0.007) were higher in females.

CONCLUSION

Adolescent depression with mixed features is more severe in women, with a higher expression of core affective symptoms and excessive fatigue. While in males, slightly higher levels of psychomotor activation are reported, in females, emotional dysregulation and excessive weeping may subtend a difference in a broader spectrum of mixed features.

The Relationship Between Workplace Burnout and Male Depression Symptom Assessed by the Korean Version of the Gotland Male Depression Scale

Screening for depression in males is important because their symptoms differ from those of females, ranging from indications of aggression to attempts at suicide. Men and women differ in their responses to job stress. There are no tools that have been verified, developed, or translated for screening male depression in Korea. Our team translated the Gotland Male Depression Scale (GMDS) into Korean. The Korean version of GMDS (K-GMDS) and Maslach Burnout Inventory-General Survey (MBI-GS) were administered to 277 office workers in one public institution. Gender differences in each scale score were measured along with the correlation between the K-GMDS and the MBI-GS. There was no significant difference in the K-GMDS score between males and females, whereas females scored significantly higher on the MBI-GS (p < .001). The correlation between the K-GMDS total score and the MBI total score (male: r = .702, p < .001, female: r = .375, p < .001) and MBI subscale scores were higher in males than females. Gender moderated the relationship between total K-GMDS and total MBI scores (p < .001). The Korean version of the GMDS is suitable for screening male depression symptoms in the workplace. The results of the K-GMDS demonstrated a strong correlation between depressive symptoms and work-related burnout among men. This study can be used as a basis for studying male depression symptoms in Korea, which has not been studied extensively. This will prove beneficial for work environments.

Male-Type Depression Mediates the Relationship between Avoidant Coping and Suicidal Ideation in Men

Despite known links between men's avoidant coping behaviours (e.g., distraction, denial, substance use) and suicide risk, little research has explored the mechanisms underpinning this relationship. This study sought to examine whether male-type depression symptoms (e.g., anger, aggression, emotion suppression), assessed by the Male Depression Risk Scale, mediate the association between avoidant coping and suicide/self-harm ideation in men. Data were drawn from an online survey of a community sample of 606 Australian men (M age = 50.11 years; SD = 15.00), conducted during the COVID-19 pandemic. Mediation analyses were applied to examine the effect of male-type depression on the association between avoidant coping and suicidal/self-harm ideation, controlling for age, resilience and the experience of two psychosocial stressors during the COVID-19 pandemic (financial stress and government restrictions). Avoidant coping was associated with suicidal/self-harm ideation, r = 0.45, p < 0.001. Results supported a mediating role of male-type depression symptoms in this relationship, R²= 0.29, P_M = 0.36, p < 0.001, underscoring the importance of screening for male-type depression symptoms to better identify men at risk of suicidal/self-harm ideation. Results also suggest a need to support men to develop effective coping strategies, particularly in the context of common psychosocial stressors experienced during the COVID-19 pandemic and beyond.

Gender differences in clinical and biochemical parameters of patients consecutively hospitalized for unipolar depression

Major Depressive Disorder (MDD) is a medical illness twice as common in women than in men lifetime. Purpose of this study is to identify gender differences in clinical and biochemical parameters in subjects affected by MDD to implement individualized treatment strategies. We recruited 234 patients (112 males and 122 females) consecutively hospitalized for MDD in Milan (Italy). Data were obtained through a screening of the clinical charts and blood analyses. Univariate analyses, binary logistic regressions and a final logistic regression model were performed. The final logistic regression model showed that female patients (compared to males) had lower plasmatic levels of hemoglobin (p = 0.020) and uric acid (p = 0.002), higher levels of cholesterol (p < 0.001), had been treated with a lower number of antidepressants (p = 0.011), presented lower red blood cells (p < 0.001) and showed more frequently comorbidity with hypothyroidism (p = 0.036). Univariate analyses identified also that women had an earlier age at onset (p = 0.043), were less likely to have comorbidity with diabetes (p = 0.002) and were less frequently treated with a psychiatric polytherapy (p < 0.001). Finally, female patients had achieved more frequently remission in the last depressive episode (p = 0.001) and were more likely to have family history for psychiatric disorders (p < 0.001) than males. Female patients globally have a better response to treatments, but they seem to be more vulnerable to specific metabolic abnormalities as showed by more frequent hypercholesterolemia and lower plasma levels of uric acid. These results have to be confirmed by further studies.

Examining the Role of Traditional Masculinity and Depression in Men's Risk for Contracting COVID-19

In the light of the COVID-19 pandemic and claims that traditional masculinity may put some men at increased risk for infection, research reporting men's health behaviors is critically important. Traditional masculine norms such as self-reliance and toughness are associated with a lower likelihood to vaccinate or follow safety restrictions. Furthermore, infection risk and traditional masculinity should be investigated in a differentiated manner including gender role orientation, underlying traditional masculine ideologies and male gender role conflict. In this pre-registered online survey conducted during March/April 2021 in German-speaking countries in Europe, 490 men completed questionnaires regarding contracting COVID-19 as confirmed by a validated test, fear of COVID-19 (FCV-19S), and experience of psychological burden due to COVID-19. In addition, depression symptomatology was assessed by using prototypical internalizing and male-typical externalizing depression symptoms. Furthermore, self-identified masculine gender orientation, endorsement of traditional masculinity ideologies, and gender role conflict were measured. A total of 6.9% of men (n = 34) reported having contracted COVID-19 since the beginning of the pandemic. Group comparisons revealed that men who had contracted COVID-19 exhibited higher overall traditional masculine ideology and gender role conflict. Logistic regression controlling for confounders (age, income, education, and sexual orientation) indicated that only depression symptoms are independently associated with the risk of having contracted COVID-19. While prototypical depression symptoms were negatively associated with the risk of having contracted COVID-19, male-typical externalizing depression symptoms were positively associated with the risk of contracting COVID-19. For traditional masculinity, no robust association for an increased risk of contracting COVID-19 could be established, while higher male-typical externalizing depression symptoms were associated with an increased risk of contracting COVID-19.

Avoidance of negative emotional contrast from worry and rumination: An application of the Contrast Avoidance Model

According to the Contrast Avoidance model (CAM), worry causes increased and sustained negative affect and such negative affect enables avoidance of a future sharp increase in negative emotion. However, only pathological worriers (vs. controls) view worry as a positive coping strategy to avoid a negative emotional contrast (NEC). We examined if rumination, which is another type of repetitive negative thought, would function similarly. Individuals with self-reported symptoms of pure generalized anxiety disorder (GAD; n = 90), pure depression (MDD; n = 85), and non-anxious/non-depressed controls (HC; n = 93) were randomly assigned to conditions where they were asked to worry, ruminate, or relax. Emotional and physiological changes were measured during worry and subsequent exposure to fearful and sad videos. We also assessed participant group differences in preference for worry or rumination as a strategy to cope with negative affect during the negative emotional video exposures. Consistent with CAM, regardless of the group, both worry and rumination enabled avoidance of NEC. Whereas worry led to greater avoidance of a fear contrast, rumination led to greater avoidance of a sadness contrast. On the other hand, relaxation enhanced NEC. Skin conductance also indicated patterns in line with CAM. In the subjectively perceived preference, the GAD group reported a greater preference for worry in coping with a fear contrast than HC. However, such a salient pattern was not found for the MDD group. Treatment implications of these findings are discussed.

[Gender-Sensitive Depression Screening (GSDS) - Further Validation of a New Self-Rating Instrument]

OBJECTIVE

To check the validity of the preliminary results with the Gender-Sensitive Depression Screening (GSDS) in two German samples of non-psychiatric outpatients.

METHODS

The psychometric validation of the GSDS-33 was performed in a sample of non-psychiatric outpatients of different clinics belonging to the Ludwig-Maximilians-University of Munich (n = 958) and in a male non-psychiatric sample of the Men's Health Center in Berlin (n = 237).

RESULTS

Findings of the first validation study of the GSDS (Möller-Leimkühler, Mühleck 2020) were largely confirmed. The data also confirmed the factors 'aggressiveness' and 'emotional control' as important components of an increasing depression risk. Compared to a standard screening the GSDS again identified more risk cases among men in the two samples (8 % and 18 %).

CONCLUSIONS

The GSDS-25 is a multidimensional, valid and reliable scale for better identifying men with a risk of depression.

New frontiers in suicide vulnerability: immune system and sex hormones

Suicide is one of the leading causes of death worldwide and men have a higher risk of attempting and completing suicide than women. Accumulating evidence leads to a possible key role of the immune system and sex hormones in psychiatric conditions associated with suicide vulnerability (e.g., major depressive disorder). Moreover, the literature highlights a dysregulation of the immune system and altered sex hormone levels in suicidal patients. Sex hormones and the immune system may have a role in suicide risk and sex differences in suicide vulnerability. This brief review emphasises a research area focused on a possible interplay between the immune system and sex hormones that may help develop a better understanding of suicide vulnerability in the perspective of sex-specific therapeutic approaches.

[Fatherhood and Depression: Dealing with Depression in the Family from the Fathers' Perspective - A Qualitative Study]

OBJECTIVE

Investigation of the experiences of depressed fathers in dealing with their depressive disorder in the family.

METHODS

17 semi-structured narrative interviews were conducted and analyzed following a Grounded Theory Approach.

RESULTS

Fathers describe individual coping strategies in dealing with their depressive disorder that aim at independently coping from their family (self-management, [non])disclosure of the disorder).

CONCLUSION

Fathers should be supported in (the decision-making process of) disclosing their illness to the family and developing coping strategies that take family needs further into account.

Examining Depression Among Perpetrators of Intimate Partner Homicide

Male depression has been recognized as an important factor in some cases of intimate partner violence but there is a paucity of literature connecting depression and intimate partner homicide (IPH). This retrospective study provides a preliminary analysis that distinguished depressed from nondepressed perpetrators of IPH from a sample of 135 cases analyzed by a coroner's homicide death review committee in Ontario, Canada. Depressed perpetrators were more likely to commit homicide-suicide and had almost 1.5 times the number of risk factors present than nondepressed perpetrators. Consistent with the existing literature, the results indicated that depressed perpetrators were significantly older, more likely to commit homicide-suicide than homicide only, more likely to have prior threats or attempts of suicide, more likely to have been abused or witnessed domestic violence as a child than nondepressed perpetrators and more likely to exhibit sexual jealousy. The implications for these findings are outlined in terms of training of mental health professionals and public awareness about the potential lethality of domestic violence.

Gender-Specific Differences in Depressive Behavior Among Forensic Psychiatric Patients

Background

Women are almost twice as likely to develop depression than men, but men commit suicide more often. One explanation for this paradox is that current depression inventories do not fully capture typical male symptoms of depression. Several studies showed that most depression symptoms in men are masked by externalizing behaviors, such as aggressiveness, addiction, and risky behavior. Here, we explored the differences in depression symptoms between men and women in a forensic psychiatric sample.

Methods

We screened 182 forensic psychiatric patients and selected a matched sample (21 women and 21 men). External symptoms of depression were assessed with the Gender-Sensitive Depression Screening (GSDS) and internal symptoms with the Beck Depression Inventory Revision.

Results

Although externalizing behaviors were similar in both groups, we found a significant relationship between external and internal depression symptoms only in men. In addition, male forensic patients with a history of suicide had higher scores in the GSDS, whereas female patients with a history of suicide had higher scores in the Beck Depression Inventory Revision.

Discussion

The finding that the GSDS detected depression symptoms in men indicates that this instrument might be useful for developing assessments to prevent suicide in forensic practice.

Sex-related effects in major depressive disorder: Results of the European Group for the Study of Resistant Depression

BACKGROUND

Sex-related effects on the evolution and phenotype of major depressive disorder (MDD) were reported previously.

METHODS

This European multicenter cross-sectional study compared sociodemographic, clinical, and treatment patterns between males and females in a real-world sample of 1410 in- and outpatients with current MDD.

RESULTS

Male MDD patients (33.1%) were rather inpatients, suffered from moderate to high suicidality levels, received noradrenergic and specific serotonergic antidepressants (ADs) as first-line AD treatment, generally higher mean AD daily doses, and showed a trend towards a more frequent administration of add-on treatments. Female MDD patients (66.9%) were rather outpatients, experienced lower suicidality levels, comorbid thyroid dysfunction, migraine, asthma, and a trend towards earlier disease onset.

CONCLUSIONS

The identified divergencies may contribute to the concept of male and female depressive syndromes and serve as predictors of disease severity and course, as they reflect phenomena that were repeatedly related to treatment-resistant depression (TRD). Especially the greater necessity of inpatient treatment and more complex psychopharmacotherapy in men may reflect increased therapeutic efforts undertaken to treat suicidality and to avoid TRD. Hence, considering sex may guide the diagnostic and treatment processes towards targeting challenging clinical manifestations including comorbidities and suicidality, and prevention of TRD and chronicity.

Anhedonia and the Relationship Between Other Depressive Symptoms and Aggressive Behavior

Depression has been linked to multiple forms of aggressive behavior in college students; however, it is unclear which aspects of depression explain this connection. Anhedonia, defined as the loss of interest and/or pleasure in previously enjoyed activities, may provide unique information about relationships between depression and aggression. Using cross-sectional data from two independent samples of college students (N = 747 and N = 736 for Study 1 and Study 2, respectively), we examined whether anhedonia helped explain the relationship between broader depressive symptoms and different forms of aggressive and antisocial behavior. Anhedonia accounted for variance in both self-directed aggression and antisocial behavior independent of gender, hostility, anger, other depressive symptoms, and cognitive distortions (Study 2). In addition, there were significant indirect effects of depressive symptoms on self-directed aggression (Studies 1 and 2) and antisocial behavior (Study 2) via anhedonia. Hypotheses involving other-directed aggression received mixed support, with anhedonia atemporally associated with other-directed aggression independent of broader depressive symptoms in Study 1, but not in Study 2. The current findings suggest that anhedonia is an important individual difference that helps explain the relationship between depression and aggressive and antisocial acts and that anhedonia may be differentially associated with various types of aggressive and antisocial behavior.

Similarities and Differences of Mental Health in Women and Men: A Systematic Review of Findings in Three Large German Cohorts

In Germany, large, population-based cohort studies have been implemented in order to identify risk and protective factors for maintaining health across the life span. The purpose of this systematic review is to analyse findings from three large ongoing cohorts and to identify sex-specific prevalence rates, risk and protective factors for mental health. Published studies from the Cooperative Health Research in the Region Augsburg (KORA), the Study of Health in Pomerania (SHIP) and the Gutenberg Health Study (GHS)), representing the southern, north-eastern and middle parts of Germany, were identified through searches of the databases PubMed and Web of Science. A total of 52 articles was identified from the start of each cohort until June 2019. Articles reporting prevalence rates of mental health [N = 22], explanatory factors for mental health [N = 25], or both [N = 5] were identified. Consistent across cohorts, higher prevalence rates of internalizing disorders were found for women and more externalizing disorders for men. Risk and protective factors for mental health included social factors, lifestyle, physical health, body mass index (BMI), diabetes, genetic and biological factors. In all areas, differences and similarities were found between women and men. The most evident were the sex-specific risk profiles for depression with mostly external risk factors for men and internal risk factors for women. Gender was not assessed directly, therefore we examined whether socioeconomic and family-related factors reflecting gender roles or institutionalized gender could be used as a proxy for gender. Overall, this systematic review shows differences and similarities in prevalence rates and determinants of mental health indicators between women and men. They underline the importance of focussing on sex specific approaches in mental health research and in the development of prevention measures. Current research on mental health still lacks focus on gender aspects. Therefore, an increased focus on sex and gender in mental health research is of great importance.

Screening for Early Signs of Paternal Perinatal Affective Disorder in Expectant Fathers: A Cluster Analysis Approach

Previous studies documented gender-related differences in the expression of Perinatal Affective Disorders. However, little attention has been paid to screening the male population during the perinatal period. This study was based on three aims: (1) to investigate the mental health of expectant fathers based on their levels of depression, anxiety, addiction, anger attacks/hostility, and somatization, identifying psychological profiles; (2) to analyze the association between these profiles and the individual variable of perceived stress; (3) and to examine the association between these profiles and the couple’s variable of marital adjustment. A total of 350 Italian expectant fathers in the last trimester of pregnancy were asked to fill in questionnaires concerning perceived stress, dyadic adjustment, psychiatric symptomatology, and depression. Three different clusters were found: “psychologically healthy men” (68%) with low levels of symptoms on all the scales; “men at risk of externalized behavioral problems” (17.1%), characterized by one or more addictive or risky behaviors and moderate levels of scales scores; and “men experiencing psychological distress” (14.9%), with the highest scores on all the scales. A significant association emerged among the perceived stress, marital adjustment, and cluster membership. These results highlight the importance of screening fathers in perinatal health services, which are still predominantly mother-centered, and underscore the necessity to create tailored and personalized interventions.

Profiles of Depressive Symptoms and Anger in Men: Associations With Postpartum Family Functioning

Background: Evidence suggests that men commonly experience depression as feelings of anger; yet, research has not investigated what this means for the manifestation of depressive symptoms in the early years of fatherhood and for key indicators of family functioning. Methods: Using data from a longitudinal cohort study of men at the normative age for entering fatherhood (28-32 years), we conducted latent class analyses to identify patterns of depressive symptoms and 3 sub-types of state anger (feeling; verbal; physical). We then assessed whether class membership was associated with paternity status (n = 535). In a subsample of fathers of infants aged up to 18 months (n = 162), we prospectively assessed associations with paternal-infant bonding, co-parenting, perceived social support, paternal involvement in childcare and alcohol use up to 2 years later. Results: Five classes emerged that differentiated men by anger and depressive symptom severity and by the degree to which men endorsed the feeling of wanting to express anger physically. Compared to the reference class with minimal symptoms, fathers had a higher probability of being in either the mild or most severe symptom classes. Men in symptomatic classes were at higher risk of lower levels of social support, co-parenting problems, and paternal-infant bonds. Class membership was not associated with alcohol use or paternal involvement in childcare. Conclusions: Our results reveal patterns of co-existing symptoms of depression and anger in fathers of infants that will be relevant to men's own need for support, their family safety, partner mental health and child developmental outcomes.

Depression and prostate cancer: implications for urologists and oncologists

Many patients with prostate cancer experience severe levels of depression, which can negatively affect their treatment and disease course. Some prostate cancer treatments can increase the severity of a patient's depression, for example, by increasing anhedonia and erectile dysfunction. Depression is often thought of as a unitary phenomenon, but multiple subtypes can be distinguished. This variety of manifestations challenges the successful application of universal antidepressant treatment options and argues for a multi-symptom assessment process that considers a patient's disease burden and their particular form of depression. Inclusion of screening and detailed diagnosis of depression can be argued to be part of good practice, and clinicians are urged to consider when and how this might be accomplished within their urological practice.

Chronic traumatic encephalopathy neuropathology might not be inexorably progressive or unique to repetitive neurotrauma

In the 20th century, chronic traumatic encephalopathy (CTE) was conceptualized as a neurological disorder affecting some active and retired boxers who had tremendous exposure to neurotrauma. In recent years, the two research groups in the USA who have led the field have asserted definitively that CTE is a delayed-onset and progressive neurodegenerative disease, with symptoms appearing in midlife or decades after exposure. Between 2005 and 2012 autopsy cases of former boxers and American football players described neuropathology attributed to CTE that was broad and diverse. This pathology, resulting from multiple causes, was aggregated and referred to, in toto, as the pathology ‘characteristic’ of CTE. Preliminary consensus criteria for defining the neuropathology of CTE were forged in 2015 and published in 2016. Most of the macroscopic and microscopic neuropathological findings described as characteristic of CTE, in studies published before 2016, were not included in the new criteria for defining the pathology. In the past few years, there has been steadily emerging evidence that the neuropathology described as unique to CTE may not be unique. CTE pathology has been described in individuals with no known participation in collision or contact sports and no known exposure to repetitive neurotrauma. This pathology has been reported in individuals with substance abuse, temporal lobe epilepsy, amyotrophic lateral sclerosis, multiple system atrophy, and other neurodegenerative diseases. Moreover, throughout history, some clinical cases have been described as not being progressive, and there is now evidence that CTE neuropathology might not be progressive in some individuals. Considering the current state of knowledge, including the absence of a series of validated sensitive and specific biomarkers, CTE pathology might not be inexorably progressive or specific to those who have experienced repetitive neurotrauma.

Suicide risk, psychological distress and treatment preferences in men presenting with prototypical, externalising and mixed depressive symptomology

Background: The prevalence of depression in men is significantly lower than women despite male suicide being higher. Therefore, improving the understanding and detection of depression in men is an important research and clinical aim.Aims: To examine the prevalence of prototypic, externalising and mixed depressive symptoms and their relation to mental illness and suicide riskMethods: Quantitative data were obtained through a survey of N = 1000 Canadian males (median age  =  49.63 years, SD = 14.60). A range of validated scales were incorporated including the PHQ-9, K6, SBQ-R and MDRS.Results: Using established cut-off scores, the proportions classified into distinct symptom groups were: not depressed (69%), prototypical (8%), mixed (12%) and externalising (11%). Risk of mental illness and suicidal risk was significantly elevated in all depressed groups. Compared to the not-depressed group, those experiencing only externalising symptoms and those with mixed symptomology were at significantly increased risk of mental illness as well current suicide risk.Conclusion: These results highlight the clinical importance of considering a broad range of potential presentations of depression in men, all of which are associated with increased suicide risk.

Trait anger and anger attacks in relation to depressive and anxiety disorders

BACKGROUND

Patients with various psychiatric disorders may suffer from feelings of anger, sometimes leading to maladaptive (e.g., aggressive) behaviors. We examined to what extent depressive and anxiety disorders, relevant clinical correlates, and sociodemographics determined the level of trait anger and the prevalence of recent anger attacks.

METHODS

In the Netherlands Study of Depression and Anxiety (NESDA), the Spielberger Trait Anger Subscale and the Anger Attacks Questionnaire were analyzed in patients with depressive (n = 204), anxiety (n = 288), comorbid (n = 222), and remitted disorders (n = 1,107), as well as in healthy controls (n = 470) based on DSM-IV criteria.

RESULTS

On average, participants were 46.2 years old (SD = 13.1) and 66.3% were female. Trait anger and anger attacks were most prevalent in the comorbid group (M = 18.5, SD = 5.9, and prevalence 22.1%), followed by anxiety disorder, depressive disorder, remitted disorder, and controls (M = 12.7; SD = 2.9, and prevalence 1.3%). Major depressive disorder, social phobia, panic disorder, and generalized anxiety disorder were most strongly associated to trait anger and anger attacks.

LIMITATIONS

Due to a cross-sectional design, it was not possible to provide evidence for temporal or causal relationships between anger and depressive and anxiety disorders.

CONCLUSIONS

Trait anger and anger attacks are linked to depressive and anxiety disorders, although the strength of the relationship differed among both anger constructs.

Consistency matters: measurement invariance of the EORTC QLQ-C30 questionnaire in patients with hematologic malignancies

PURPOSE

To ensure that observed differences in the scores of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) reflect actual differences in health-related quality of life (HRQoL) rather than measurement bias, measurement invariance needs to be established. We investigated the assumption of measurement invariance of the EORTC QLQ-C30 in patients with hematological malignancies across age, sex, comorbidity, disease type, and time.

METHODS

We used a large database of patients with hematological malignancies, which included HRQoL data collected with the EORTC QLQ-C30. We used the structural equation modeling approach to test for measurement (metric and scalar) invariance across groups (age, sex, comorbidity, disease) and time (baseline, 1 month and 2 month follow-up). Longitudinal invariance was examined in a subgroup of patients diagnosed with myelodysplastic syndromes.

RESULTS

Confirmatory factor analyses demonstrated full measurement invariance for age and comorbidity and over time, while support for partial scalar invariance was obtained for sex and disease. Violations of invariance for sex were observed for items of the physical functioning scale and the emotional functioning scale, while for disease type, violations of invariance were observed for items of the physical functioning scale, emotional functioning scale, and the cognitive functioning scale.

CONCLUSIONS

Our findings support measurement invariance of the EORTC QLQ-C30 in a large sample of patients with hematological malignancies. The results showed that the number of non-invariant items was negligible, suggesting that this questionnaire is a valid and robust measurement tool in patients with hematological malignancies, also for comparisons across groups and time.

Couples' prenatal bonding to the fetus and the association with one's own and partner's emotional well-being and adult romantic attachment style

OBJECTIVE

Developing an emotional bond to the fetus is a highly relevant task for both parents. However, research on the influence of emotional well-being and relationship dynamics on parental-fetal bonding is limited, especially regarding the paternal experience. Additionally, the roles of prenatal anxiety and hostility in parental bonding need further investigation. The aim of this study was to investigate the importance of one's own anxiety and hostility, adult romantic attachment style and one's partner's anxiety and hostility for parental-fetal bonding quality and intensity.

DESIGN

Data were assessed cross-sectionally and analyzed using linear regression models.

SETTING

The study took place at the University Medical Center Hamburg-Eppendorf, Germany.

PARTICIPANTS

Ninety-three pregnant women and their partners (total n = 186).

MEASUREMENTS AND FINDINGS

Participants completed questionnaires in mid to late pregnancy. For mothers, higher levels of hostility and attachment-related avoidance were associated with lower bonding quality. Unexpectedly, higher levels of partner hostility were associated with higher bonding quality. Fathers with higher attachment-related avoidance reported lower bonding intensity. Neither maternal bonding intensity nor paternal bonding quality was associated with the predictor variables.

KEY CONCLUSION

Prenatal bonding is individually influenced by emotional well-being and romantic attachment styles, with different effects in mothers and fathers.

IMPLICATIONS FOR PRACTICE

Potential negative emotional states and couple dynamics in the peripartum period should be addressed in prenatal care. Birth preparation classes might be an ideal context to generally inform parents about these topics. Distressed parents might benefit from interdisciplinary support focusing on perinatal mental health and parental-fetal bonding.

The Prevalence and Risk Factors of Undiagnosed Depression and Anxiety Disorders Among Patients With Inflammatory Bowel Disease

BACKGROUND

Inflammatory bowel disease (IBD) is associated with a high prevalence of comorbid depressive and anxiety disorders. A significant proportion of IBD patients with comorbid psychiatric disorders remain undiagnosed and untreated, but factors associated with diagnosis are unknown. We evaluated the prevalence of undiagnosed depression and anxiety in an IBD cohort, along with the associated demographic and clinical characteristics.

METHODS

We obtained data from the enrollment visit of a cohort study of psychiatric comorbidity in immune-mediated diseases including IBD. Each participant underwent a Structured Clinical Interview for DSM-IV-TR Axis I Disorders (SCID) to identify participants who met lifetime criteria for a diagnosis of depression or anxiety. Those with a SCID-based diagnosis were classified as diagnosed or undiagnosed based on participant report of a physician diagnosis.

RESULTS

Of 242 eligible participants, 97 (40.1%) met SCID criteria for depression, and 74 (30.6%) met criteria for anxiety. One-third of participants with depression and two-thirds with anxiety were undiagnosed. Males were more likely to have an undiagnosed depressive disorder (odds ratio [OR], 3.36; 95% confidence interval [CI], 1.28-8.85). Nonwhite participants were less likely to have an undiagnosed anxiety disorder (OR, 0.17; 95% CI, 0.042-0.72).

CONCLUSION

Our findings highlight the importance of screening for depression and anxiety in patients with IBD, with particular attention to those of male sex and with a lower education level.

Acquired Hearing Loss, Anger, and Emotional Distress: The Mediating Role of Perceived Disability

The aim of the study was to test whether acquired hearing loss (AHL)-related perceived disability mediates the association between AHL and psychological outcomes, including anger. Two-hundred ninety-seven consecutive outpatients with AHL assessed by pure tone average (PTA) loss completed the following: Hearing Handicap Inventory for Adults (HHIA), State-Trait Anger Expression Inventory-2 (STAXI-2), Brief Symptom Inventory (BSI), Diagnostic Criteria for Use in Psychosomatic Research (DCPR), and Social Functioning Questionnaire. In the sample, composed of 44.5% males with a mean age of 53.8 and a mean PTA of 30.7, AHL was associated to perceived hearing handicap, also correlating to all psychological measures except DCPR demoralization. Associations were stronger between the HHIA-Emotional Subscale, STAXI-2 State Anger and Feeling Angry, and BSI-Somatization, Interpersonal Sensitivity, Depression, and Psychoticism. Perceived disability predicted the presence of almost all psychosocial outcomes and confirms to be the most significant target of clinical action.

Cold temperatures, stress, and violence

The relation between temperature and violence was found in many studies. However, the results of such studies demonstrated only that uncomfortably hot temperatures increase violence. There seem to be no data on the effect of cold temperatures. We studied the relation between temperature and violence for the Russian Federation because the Russian Federation is a country with huge climatic differences. Two types of the analysis of the data were applied. In Analysis 1 average yearly temperatures were used. For violent crimes a decrease in temperature resulted in the increase of the crimes after taking into account three socioeconomic variables. Analysis 2 was based on monthly data. Violence was high in winter and spring months but low in autumn months. In our opinion, the conventional models that are used to clarify the effect of hot temperatures cannot explain our results. We hypothesize that long periods of cold temperatures can be considered as mild chronic stress. Chronic stress may exert depression and depression is associated with irritability and anger. In some situations these emotions may stimulate violence. An increase in violence associated with city living and economic downturns may partially be a consequence of mild chronic stress.

Parental depressive symptoms as a risk factor for child depressive symptoms; testing the social mediators in internationally adopted children

Parental depressive symptoms have shown to be associated with offspring depression but much of the research has been focused on maternal depression. The aim of our study was to investigate the extent to which depressive symptoms of both parents associate with offspring depressive symptoms and whether social factors mediate these associations using data from adopted children with no shared genetic background. Data were derived from the Finnish Adoption survey study (a subsample of adopted children aged between 9 and 12 years, n = 548). Parental depressive symptoms were measured using short version of the General Health Questionnaire and Children's Depression Inventory (CDI) was used to measure depressive symptoms in adoptees. Paternal depressive symptoms were related to the total CDI (B = 0.33, p = 0.05) and two dimensions of offspring depressive symptoms: negative mood (B = 0.10, p = 0.03) and interpersonal problems (B = 0.06, p = 0.009). These associations remained significant even when adjusted for child's age and gender, age at adoption, type of placement before adoption, continent of birth and adoptive family's SES. No associations were found between maternal and any dimensions of offspring depressive symptoms. No information about the mental health of biological parents was available. We interpret the results as demonstrating that intergenerational transmission of depressive symptoms is not solely related to shared genes. Also, the results highlight the association of paternal depression with offspring depressive symptoms.

The androgen model of suicide completion

Suicide is a devastating public health issue that imposes severe psychological, social, and economic burdens not only for the individuals but also for their relatives, friends, clinicians, and the general public. Among the different suicidal behaviors, suicide completion is the worst and the most relevant outcome. The knowledge of biological etiopathological mechanisms involved in suicide completion is limited. Hitherto, no objective markers, either alone or in combination, can reliably predict who will complete a suicide. However, such parameters are strongly needed to establish and optimize prediction and prevention. We introduce here a novel ideation-to-completion framework in suicide research and discuss the problems of studies aiming at identifying and validating clinically useful markers. The male gender is a specific risk factor for suicide, which suggests that androgen effects are implicated in the transition from suicidal ideation to suicide completion. We present multiple lines of direct and indirect evidence showing that both an increased prenatal androgen load (with subsequent permanent neuroadaptations) and increased adult androgen activity are involved in suicide completion. We also review data arguing that modifiable maternal behavioral traits during pregnancy contribute to the offspring's prenatal androgen load and increase the risk for suicide completion later in life. We conclude that in utero androgen exposure and adult androgen levels facilitate suicide completion in an synergistic manner. The androgen model of suicide completion provides the basis for the development of novel predictive and preventive strategies in the future.

Violence Exposure and Mental Health of College Students in the United States

Background: Despite the well-established link between exposure to violence and mental health problems, less is known about this association among college students. The current study aimed to investigate the association between history of exposure to violence and mental health of American college students. Methods: Healthy Mind Study (HMS, 2016⁻2017) is a national online survey of 41,898 adult college students. The independent variable was lifetime history of exposure to violence (psychological, physical, and sexual). The dependent variables were anxiety, depression, and suicidality. Race, age, gender, sexual orientation, parental education, financial stress, transfer status, enrollment status, and graduate status were covariates. Linear and logistic regression models were used for data analysis. Results: History of exposure to violence was associated with all three aspects of poor mental health, namely general anxiety, depression, and suicidality. These associations were independent of covariates and type of abuse. Conclusions: There is a need to address various mental health needs of college students who have experienced various forms of violence. College students who screen positive for history of violence exposure should be evaluated for anxiety, depression, and suicidal behaviors.

Differences in the Expression of Symptoms in Men Versus Women with Depression: A Systematic Review and Meta-analysis

OBJECTIVE

While some studies suggest that men and women report different symptoms associated with depression, no published systematic review or meta-analysis has analyzed the relevant research literature. This article aims to review the evidence of gender differences in symptoms associated with depression.

METHODS

PubMed, Cochrane, and PsycINFO databases, along with further identified references lists, were searched. Thirty-two studies met the inclusion criteria. They included 108,260 participants from clinical and community samples with a primary presentation of unipolar depression. All 32 studies were rated for quality and were tested for publication bias. Meta-analyses were conducted on the 26 symptoms identified across the 32 studies to assess for the effect of gender.

RESULTS

The studies indicate a small, significant association of gender with some symptoms. Depressed men reported alcohol/drug misuse (Hedges's g = 0.26 [95% confidence interval (CI), 0.11-0.42]) and risk taking/poor impulse control (g = 0.58 [95% CI, 0.47-0.69]) at a greater frequency and intensity than depressed women. Depressed women reported symptoms at a higher frequency and intensity that are included as diagnostic criteria for depression such as depressed mood (g = -0.20 [95% CI, -0.33 to -0.08]), appetite disturbance/weight change (g = -0.20 [95% CI, -0.28 to -0.11]), and sleep disturbance (g = -0.11 [95% CI, -0.19 to -0.03]).

CONCLUSIONS

Results are consistent with existing research on gender differences in the prevalence of substance use and mood disorders, and of their co-occurrence. They highlight the potential utility of screening for substance misuse, risk taking, and poor impulse control when assessing depression in men. Future research is warranted to clarify gender-specific presentations of depression and co-occurring symptoms.

Psychological Predictors of Sexual Intimate Partner Violence against Black and Hispanic Women

Background: Although various types of intimate partner violence (IPV) tend to co-occur, risk factors of each type of IPV may differ. At the same time, most of the existing literature on risk factors of IPV among minorities has used a cross-sectional design and has focused on physical rather than sexual IPV. We conducted the current study to compare Black and Hispanic women for psychological predators of change in sexual IPV over time. Methods: Using data from the Fragile Families and Child Wellbeing Study (FFCWS), this study followed 561 Black and 475 Hispanic women with their male partners for four years. Independent variables included male partners' depression, anxiety, problem alcohol use, and male-to-female physical and psychological IPV perpetration. The dependent variable was sexual IPV reported by female partners, measured at baseline, two years, and four years later. Covariates included age, income, marital status and educational level. We used a multi-group latent growth curve model (LGCM) to explain intercept, linear, and quadratic slopes, which represent the baseline, and linear and curvilinear trajectories of male-to-female sexual IPV, where groups were defined based on ethnicity. Results: Psychological IPV was associated with sexual IPV at baseline among both ethnic groups. The male partner's depression was a risk factor for an increase in sexual IPV over time among Black but not Hispanic women. Anxiety, problem alcohol use and physical IPV did not have an effect on the baseline or change in sexual IPV over time. Psychological IPV was not associated with an increase in sexual IPV over time in either ethnic groups. Conclusions: There is a need for screening of sexual IPV in the presence of psychological IPV among minority women. There is also a need for screening and treatment of male partners' depression as a strategy to reduce sexual IPV among Black women.

Six-year longitudinal study of pathways leading to explosive anger involving the traumas of recurrent conflict and the cumulative sense of injustice in Timor-Leste

PURPOSE

Cumulative evidence suggests that explosive anger may be a common reaction among survivors of mass conflict. However, little is known about the course of explosive anger in the years following mass conflict, or the psychosocial factors that influence the trajectory of that reaction pattern. We examined these issues in a 6-year longitudinal study (2004-2010) conducted among adult residents of a rural and an urban village in Timor-Leste (n = 1022).

METHODS

We derived a brief, context-specific index of explosive anger using qualitative methods. Widely used measures of post-traumatic stress disorder (PTSD) and severe psychological distress were calibrated to the Timor context. We developed an index of the cumulative sense of injustice related to consecutive historical periods associated with conflict in Timor-Leste. We applied partial structural equation modeling (SEM) to examine pathways from baseline explosive anger, socio-demographic factors, recurrent trauma, mental health indices (PTSD, severe psychological distress) and the sense of injustice, to explosive anger.

RESULTS

Half of the sample with explosive anger at baseline continued to report that reaction pattern after 6 years; and a third of those who did not report explosive anger at baseline developed the response by follow-up. A symmetrical pattern of younger age, female gender and the trauma count for the preceding historical period predicted explosive anger at each assessment point. The sense of injustice was related to explosive anger at follow-up. Explosive anger was associated with impairment in functioning and conflict with the intimate partner and wider family.

CONCLUSIONS

Sampling constraints caution against generalizing our findings to other populations. Nevertheless, our data suggest that explosive anger may persist for a prolonged period of time following mass conflict and that the response pattern is initiated and maintained by recurrent trauma exposure associated with a sense of injustice. Averting recurrence of mass violence and addressing persisting feelings of injustice may assist in reducing anger in conflict-affected societies. Whether explosive anger at the individual level increases risk of collective violence under conditions of social and political instability requires further inquiry.

Lurasidone for major depressive disorder with mixed features and irritability: a post-hoc analysis

OBJECTIVE

The aim of this post-hoc analysis was to evaluate the efficacy of lurasidone in treating major depressive disorder (MDD) with mixed features including irritability.

METHODS

The data in this analysis were derived from a study of patients meeting DSM-IV-TR criteria for unipolar MDD, with a Montgomery-Åsberg Depression Rating Scale (MADRS) total score ≥26, presenting with two or three protocol-defined manic symptoms, and who were randomized to 6 weeks of double-blind treatment with either lurasidone 20-60 mg/d (n=109) or placebo (n=100). We defined "irritability" as a score ≥2 on both the Young Mania Rating Scale (YMRS) irritability item (#5) and the disruptive-aggressive item (#9). Endpoint change in the MADRS and YMRS items 5 and 9 were analyzed using a mixed model for repeated measures for patients with and without irritability.

RESULTS

Some 20.7% of patients met the criteria for irritability. Treatment with lurasidone was associated with a significant week 6 change vs. placebo in MADRS score in both patients with (-22.6 vs. -9.5, p<0.0001, effect size [ES]=1.4) and without (-19.9 vs. -13.8, p<0.0001, ES=0.7) irritability. In patients with irritable features, treatment with lurasidone was associated with significant week 6 changes vs. placebo in both the YMRS irritability item (-1.4 vs. -0.3, p=0.0012, ES=1.0) and the YMRS disruptive-aggressive item (-1.0 vs. -0.3, p=0.0002, ES=1.2).

CONCLUSIONS

In our post-hoc analysis of a randomized, placebo-controlled, 6-week trial, treatment with lurasidone significantly improved depressive symptoms in MDD patients with mixed features including irritability. In addition, irritability symptoms significantly improved in patients treated with lurasidone.

Socio-demographic patterns of posttraumatic stress disorder in Medellin, Colombia and the context of lifetime trauma exposure

Colombia, South America is currently transitioning to post-conflict status following 6 decades of armed conflict. The population has experienced extensive exposures to potentially traumatic events throughout the lifespan. Sources of trauma exposure include the prolonged armed insurgency, narco-trafficking violence, urban gang violence, violent actions of criminal bands, intra-familial violence, gender-based violence, and sex trafficking. Exposure to potentially traumatic events is related to a variety of psychiatric outcomes, in particular, posttraumatic stress disorder. Given this context of lifetime trauma exposure, socio-demographic patterns of posttraumatic stress disorder were explored in a sample of residents of Medellin, Colombia, the nation's second largest city and a nexus for multiple types of trauma exposure.

New Fathers' Perinatal Depression and Anxiety-Treatment Options: An Integrative Review

More than 10% of fathers experience depression and anxiety during the perinatal period, but paternal perinatal depression (PPND) and anxiety have received less attention than maternal perinatal mental health problems. Few mainstream treatment options are available for men with PPND and anxiety. The aim of this literature review was to summarize the current understanding of PPND and the treatment programs specifically designed for fathers with perinatal depression. Eight electronic databases were searched using a predefined strategy, and reference lists were also hand searched. PPND and anxiety were identified to have a negative impact on family relationships, as well as the health of mothers and children. Evidence suggests a lack of support and tailored treatment options for men having trouble adjusting to the transition to fatherhood. Of the limited options available, cognitive behavioral therapy, group work, and blended delivery programs, including e-support approaches appear to be most effective in helping fathers with perinatal depression and anxiety. The review findings have important implications for the understanding of PPND and anxiety. Future research is needed to address the adoption of father-inclusive and father-specific models of care to encourage fathers' help-seeking behavior. Inclusion of male-specific requirements into support and treatment options can improve the ability of services to engage new fathers. Psychotherapeutic intervention could assist to address the cognitive differences and dissonance for men adjusting to the role of father, including male identity and role expectations.

The 5-HT1A receptor in Major Depressive Disorder

Major Depressive Disorder (MDD) is a highly prevalent psychiatric diagnosis that is associated with a high degree of morbidity and mortality. This debilitating disorder is currently one of the leading causes of disability nationwide and is predicted to be the leading cause of disease burden by the year 2030. A large body of previous research has theorized that serotonergic dysfunction, specifically of the serotonin (5-HT) 1A receptor, plays a key role in the development of MDD. The purpose of this review is to describe the evolution of our current understanding of the serotonin 1A (5-HT1A) receptor and its role in the pathophysiology MDD through the discussion of animal, post-mortem, positron emission tomography (PET), pharmacologic and genetic studies.

Depression or anxiety and all-cause mortality in adults with atrial fibrillation--A cohort study in Swedish primary care

OBJECTIVE

Our aim was to study depression and anxiety in atrial fibrillation (AF) patients as risk factors for all-cause mortality in a primary care setting.

METHODS

The study population included adults (n = 12 283) of 45 years and older diagnosed with AF in 75 primary care centres in Sweden. The association between depression or anxiety and all-cause mortality was explored using Cox regression analysis, with hazard ratios (HRs) and 95% confidence intervals (95% CIs). Analyses were conducted in men and women, adjusted for age, educational level, marital status, neighborhood socio-economic status (SES), change of neighborhood status and anxiety or depression, respectively, and cardiovascular co-morbidities. As a secondary analysis, background factors and their association with depression or anxiety were explored.

RESULTS

The risk of all-cause mortality was higher among men with depression compared to their counterparts without depression even after full adjustment (HR = 1.28, 95% CI 1.08-1.53). For anxiety among men and anxiety or depression among women with AF, no associations were found. Cerebrovascular disease was more common among depressed AF patients.

CONCLUSIONS

Increased awareness of the higher mortality among men with AF and subsequent depression is called for. We suggest a tight follow-up and treatment of both ailments in clinical practice.

Gendered Manifestations of Depression and Help Seeking Among Men

Men who do not seek help for mental health problems may experience unnecessary suffering which ultimately affects the well-being of themselves and others. Gendered manifestations of depressive symptoms may play an important role in why some men do not seek help for mental health issues. Using data from 2,382 male respondents in the National Comorbidity Survey Replication, the authors examined the relationship that both traditional and male-typical symptoms of depression had on the help-seeking behaviors of men. Traditional symptoms increased the odds of seeking help for depression for all men. Male-typical symptoms, however, did not increase the odds of seeking help for depression or another mental health concern. Both traditional and male-typical symptoms increased the odds of initially seeking help from a medical provider, and men with male-typical symptoms had an overall higher likelihood of seeking help from a medical provider. Consequently, it is important that medical professionals assess for depression even when it is not a presenting concern.

Sex-specific regulation of NUCB2/nesfatin-1: Differential implication in anxiety in obese men and women

Nesfatin-1 is cleaved from nucleobindin2 (NUCB2) and implicated in the regulation of hunger and satiety as anorexigenic peptide hormone. Circulating NUCB2/nesfatin-1 is elevated in obesity and decreased in anorexia nervosa. In addition, a role in the regulation of stress, anxiety and depression has been demonstrated. First evidence suggested that NUCB2/nesfatin-1 might be regulated in a sex-specific manner. Thus, we investigated NUCB2/nesfatin-1 plasma levels in association with perceived stress, anxiety and depressiveness in obese men and women. We enrolled 140 inpatients (87 female, 53 male; body mass index, BMI, 30.3-81.7 kg/m(2)) hospitalized due to obesity with mental and somatic comorbidities. Perceived stress (PSQ-20), anxiety (GAD-7), and depressiveness (PHQ-9) were measured psychometrically, and at the same time NUCB2/nesfatin-1 plasma levels by ELISA. Males and females did not differ in terms of age and BMI. NUCB2/nesfatin-1 did not show a correlation with age or BMI. Mean NUCB2/nesfatin-1 levels (+25%, p<0.001) as well as mean scores for perceived stress (+26%, p < 0.01), anxiety (+54%, p < 0.001) and depressiveness (+32%, p = 0.02) were higher in females compared to males. Scores for perceived stress (r = 0.39; p < 0.001) and depressiveness (r = 0.35; p < 0.01) showed a positive correlation with NUCB2/nesfatin-1 in women, while in men no correlation was observed (p>0.19). The strongest association was observed between NUCB2/nesfatin-1 and anxiety with a positive correlation in women (r = 0.54; p < 0.001), while in men even an inverse correlation was found (r = -0.32; p = 0.03). This result was reflected in higher NUCB2/nesfatin-1 levels in women with high versus low anxiety (+51%, p<0.001) and an opposite alteration in men (-17%, p = 0.04) after a median split into two groups with high and low anxiety. In conclusion, circulating NUCB2/nesfatin-1 showed a positive correlation with anxiety, perceived stress, and depressiveness in obese women. In men, no correlation with perceived stress and depressiveness was observed, whereas the association with anxiety was inverse, pointing towards a sex-specific regulation. These results corroborate the suggestion of NUCB2/nesfatin-1 being relevantly involved in the regulation of mood and stress in a sex-specific way.

Influence of Sex on Suicidal Phenotypes in Affective Disorder Patients with Traumatic Childhood Experiences

Objectives

In the current study, we aimed to investigate the impact of childhood trauma on suicidal behaviour phenotypes in a group of patients with diagnosed affective disorder (unipolar or bipolar affective disorder).

Patients and Methods

Patients with and without a history of childhood abuse, measured by Childhood Trauma Questionnaire (CTQ), were assessed to explore risks for suicidal behaviour (including suicide attempt, self-harm and non-suicidal self-injury). The tested sample consisted of 258 patients (111 males and 147 females, in-patients and out-patients at the Department of Psychiatry and Psychotherapy, Medical University of Vienna and University Hospital Tulln, Lower Austria). Psychiatric diagnoses were derived from the SCAN (Schedules for Clinical Assessment in Neuropsychiatry) interview. In addition, patients were administered the Lifetime Parasuicidal Count (LPC), Suicidal Behaviour Questionnaire (SBQ-R), and Viennese Suicide Risk Assessment Scale (VISURIAS) questionnaires.

Results

In contrast to male suicide attempters, female suicide attempters showed both significantly higher total CTQ scores (p<0.001), and higher CTQ subscores (emotional, physical and sexual abuse, as well as emotional and physical neglect) in comparison to the non-suicidal control group. Besides, females with a history of self-harming behaviour (including suicidal intention) and Non-Suicidal-Self Injury (NSSI) had significantly higher CTQ total scores (p<0.001) than the control group.

Conclusion

These findings suggest gender differences in suicidal behaviour after being exposed to childhood trauma.

A critical review of chronic traumatic encephalopathy

Chronic traumatic encephalopathy (CTE) has been described in the literature as a neurodegenerative disease with: (i) localized neuronal and glial accumulations of phosphorylated tau (p-tau) involving perivascular areas of the cerebral cortex, sulcal depths, and with a preference for neurons within superficial cortical laminae; (ii) multifocal axonal varicosities and axonal loss involving deep cortex and subcortical white matter; (iii) relative absence of beta-amyloid deposits; (iv) TDP-43 immunoreactive inclusions and neurites; and (v) broad and diverse clinical features. Some of the pathological findings reported in the literature may be encountered with age and other neurodegenerative diseases. However, the focality of the p-tau cortical findings in particular, and the regional distribution, are believed to be unique to CTE. The described clinical features in recent cases are very similar to how depression manifests in middle-aged men and with frontotemporal dementia as the disease progresses. It has not been established that the described tau pathology, especially in small amounts, can cause complex changes in behavior such as depression, substance abuse, suicidality, personality changes, or cognitive impairment. Future studies will help determine the extent to which the neuropathology is causally related to the diverse clinical features.

Prevention of homicidal behaviour in men with psychiatric disorders

OBJECTIVES

Homicide is overwhelmingly committed by men compared to women. Conservative estimates suggest that more than a third of these individuals have a treatable psychiatric disorder. These data present an opportunity to mental health clinicians to assist in the prevention of homicide by improving men's mental health.

METHODS

We review the current literature on men's mental health with a focus on assessing and reducing homicide risk in men with psychiatric conditions.

RESULTS

Bipolar disorder and schizophrenia appear to share a neural endophenotype that is a risk factor for homicide. Dual disorders, or the presence of a substance use disorder with other major mental illness, are a major risk factor for homicide in males. Dual diagnosis disorders, personality disorders and pathological traits and male depression share emotion dysregulation, irritability, and reactive aggression. Promoting physician education, addressing firearm safety, reducing the reluctance of men relative to women to engage in help-seeking behaviour, and using targeted risk interviews which integrate these data are all currently recommended.

CONCLUSIONS

The main focus in prevention of homicidal behaviour in males with psychiatric disorders should be to identify high risk groups, to provide adequate treatment, and to facilitate compliance with long-term treatment while considering male specific problems and needs.
