Type of cycle, temperament and childhood trauma are associated with lithium response in patients with bipolar disorders.

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.

Postpartum Depression and Inflammatory Biomarkers of Neutrophil-Lymphocyte Ratio, Platelet-Lymphocyte Ratio, and Monocyte-Lymphocyte Ratio: A Prospective Observational Study.

OBJECTIVES: Postpartum depression (PPD) is a severe mental health disorder affecting a significant proportion of mothers, often undiagnosed and untreated, with potential long-term effects. While numerous studies have identified risk factors for PPD, the relationship between inflammatory markers and PPD remains unknown. This study aimed to investigate the potential correlation between indirect inflammatory markers, specifically neutrophil-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-lymphocyte ratio (MLR), and the risk of developing PPD, assessed by the Edinburgh Postnatal Depression Scale (EPDS). DESIGN: This was a prospective observational study conducted in a second-level university hospital, from December 2019 to February 2021. PARTICIPANTS: A total of 211 full-term pregnant women were enrolled. Exclusion criteria included specific psychiatric diagnoses, such as severe intellectual disability, schizophrenia, schizoaffective disorder, delusional disorder, bipolar or other unspecified psychotic spectrum disorders. Additionally, pregnancies affected by gestational and pregestational diabetes, chronic hypertension, gestational hypertension, preeclampsia/eclampsia, intrauterine fetal growth restriction, preterm delivery, multiple pregnancies, and fetal abnormalities detected prenatally were excluded. METHODS: Socio-demographic and clinical data were recorded. Blood samples for complete blood count were obtained at hospital admission, focusing on NLR, PLR, and MLR. Analyses were conducted in our laboratory using standard techniques. The postpartum PPD evaluation was conducted 3 days after delivery, with the EPDS Italian version. Statistical analyses included descriptive statistics, group comparisons using t tests or Wilcoxon rank-sum tests for continuous variables, and Pearson χ2 or Fisher's exact tests for categorical variables. Correlation analyses employed Pearson correlation or Spearman's rank correlation tests. Simple logistic regression models, adjusted for various baseline patient characteristics, explored the correlation between inflammatory markers (PLR, NLR, MLR) and postpartum depressive symptoms. Version 4.1.3 of RStudio statistical software was utilized. RESULTS: Overall, 211 pregnant women enrolled were categorized into two groups based on the EPDS scores: <10 (176 patients) and ≥10 (35 patients). The two groups demonstrated homogeneity in different socio-demographic factors. Stepwise regression analysis indicated that PLR, NLR, and MLR were not significantly associated with these variables. The scatterplot of PLR, NLR, and MLR on EPDS was stratified for EPDS groups. The Wilcoxon rank-sum test applied to PLR, NLR, and MLR values and EPDS groups did not reveal a statistical relationship. Additional analyses were conducted using the estimated odds ratios of the logistic regression model on EPDS groups, considering both continuous and binary values of indirect inflammatory markers (PLR, NLR, MLR). The results indicated the absence of a statistical relationship. LIMITATIONS: Our evaluation was restricted to the postpartum period, and data for the first and second trimesters of pregnancy are lacking. CONCLUSIONS: Our findings did not evidence a correlation between indirect inflammatory markers (NLR, PLR, and MPL) and PPD. This novel finding prompts further evaluation of the role of indirect inflammatory markers in PPD, highlighting the need for additional research to clarify the complex relationship between inflammation and psychological health in the postpartum period.

Longitudinal trajectories of anxiety and depression in subjects with different mental disorders after one year in the COVID-19 pandemic.

The aim of this study was to prospectively assess the development and trajectories of anxiety and depressive symptoms among subjects with different mental disorders, during the 3rd wave of the COVID-19 pandemic (T0, March-April 2021) while strict containment measures were applied in Italy, and after 3 months (T1, June-July 2021), with reduced restrictive measures. A sample of 527 subjects, with different DSM-5 diagnoses, was enrolled at nine Italian psychiatric outpatient services. Assessments at T0 and T1 included the Generalized Anxiety Disorder 7-Item (GAD-7) for anxiety symptoms, and the Patient Health Questionnaire-9 (PHQ-9) for depressive symptoms. Differences in anxiety and depressive symptoms rates emerged across different mental disorders and a general improvement at T1 was detected for all of them in both the GAD-7 and PHQ-9 scores, except for Psychosis and Obsessive-Compulsive Disorder (OCD). Patients with Feeding and Eating Disorders (FED) reported statistically significantly higher: GAD-7 scores than those with Bipolar Disorder (BD), at both times, and Anxiety Disorders at baseline; PHQ-9 scores than all other diagnostic categories, at both times. Unemployment, no COVID-19 infection, OCD were predictive variables related to GAD-7 scores at T1, while being unmarried, BD or FED related to PHQ-9 scores at T1. Subjects with mental disorders reported anxiety and depressive symptoms during the third pandemic wave and most of patients showed an improvement over a 3-month follow-up, despite differences emerged among diagnostic categories and for the variables involved. Further studies are needed to deepen knowledge on pandemic impact on patients with mental disorders.

Is there a correlation between prepartum anaemia and an increased likelihood of developing postpartum depression? A prospective observational study.

PURPOSE: Postpartum depression (PPD) represents a significant challenge to maternal and child health. Early screening for PPD is essential to ensure appropriate treatment and support. The present study aimed to assess whether maternal prepartum anaemia influences the likelihood of developing PPD within 3 days after delivery. METHODS: In collaboration with the Department of Psychiatry, a prospective observational study was carried out at the Gynaecology and Obstetrics Department of the University of Campania "Luigi Vanvitelli" in Naples. A total of 211 full-term pregnant women were enrolled, and their predelivery haemoglobin value was recorded. Women with gestational diabetes, hypertension, pre-eclampsia, intrauterine growth restriction, intellectual disability, or pre-existing diagnosis of psychotic spectrum disorder were excluded. Participants provided written informed consent to fill out the Edinburgh Postnatal Depression Scale (EPDS) 3 days after delivery. EPDS cut-off score of ≥ 10 was used to identify women at risk of developing PPD. Statistical analysis was performed using Student's t test, the Wilcoxon Rank Sum test, and linear regression. RESULTS: The participants were categorized into 2 groups based on EPDS scores: EPDS < 10 (176 patients) or EPDS ≥ 10 (35 patients). The two groups showed homogeneity in terms of socio-demographic and clinical characteristics. The mean haemoglobin values of anaemic pregnant women in the EPDS ≤ 10 group (11.78 ± 1.39 g/dl) and the EPDS > 10 group (11.62 ± 1.27 g/dl) were not significantly different (p = 0.52). There was no significant correlation between the predelivery haemoglobin value and the EPDS postpartum score of < 10 or ≥ 10. The Wilcoxon Rank Sum test and the estimated coefficients of the linear regression model did not show any statistical relationship between continuous and binary haemoglobin values. CONCLUSIONS: Our study found that maternal prepartum anaemia did not negatively impact the likelihood of developing postpartum depressive symptoms, in the first 3 days after delivery.

The interplay between mentalization, personality traits and burnout in psychiatry training: Results from a large multicenter controlled study.

BACKGROUND: A better characterization of educational processes during psychiatry training is needed, both to foster personal resilience and occupational proficiency. METHODS: An adequate coverage of medical residents at the national level was reached (41.86% of the total reference population, 29 out of 36 training centers-80.55%). Controls were recruited among residents in other medical specialties. All participants were assessed by questionnaires to evaluate early life experiences, attachment style, personality traits, coping strategies, emotional competencies. A Structural Equation Model (SEM) framework was employed to investigate the interplay between individual factors. RESULTS: A total sample of 936 people was recruited (87.9% response-rate; 645 residents in psychiatry, 291 other medical residents). Psychiatry trainees reported a higher prevalence of adverse childhood experiences (emotional abuse, emotional neglect, physical neglect), greater attachment insecurity (anxious or avoidant) in comparison to other medical trainees. Psychiatry residents also reported higher social support-seeking as a coping strategy, lower problem-orientation, and lower transcendence. Lower neuroticism, higher openness to experience, and higher emotional awareness were also observed in psychiatry trainees. Psychiatry training was associated with a redefinition of conflict management skills as a function of seniority. The SEM model provided support for an interplay between early traumatic experiences, mentalization skills (coping strategies, emotion regulation), interpersonal competencies and occupational distress. CONCLUSIONS: The findings of the present study supported a theoretical model based on mentalization theory for the interactions between personal and relational competencies in psychiatry training, thus providing potential target of remodulation and redefinition of this specific process of education.

New trends in personalized treatment of depression.

PURPOSE OF REVIEW: Major depressive disorder (MDD) is a common and burdensome severe mental disorder, which is expected to become the leading cause of disease burden worldwide. Most patients with MDD remain untreated/undertreated. For many decades "a trial and error" approach has been adopted for selecting the best treatment plan for each individual patient, but more recently a personalized treatment approach has been proposed, by taking into account several individual and clinical factors (e.g., clinical stage, comorbidity, duration of illness). Therefore, the aim of this study is to address the most relevant innovations in the personalized treatment plan for patients with MDD. RECENT FINDINGS: In recent years, several pharmacological and nonpharmacological innovations have been introduced in the treatment of patients with MDD. As regards pharmacological treatments, the newly developed drugs have an innovative mechanism of action, targeting the glutamatergic systems. These drugs are highly effective in improving depressive symptoms, with a good level of safety and tolerability. As regards nonpharmacological interventions, innovations include both new strategies targeting different domains (e.g., lifestyle interventions aiming to improve the physical symptoms of depression or virtual reality) and classical interventions provided through innovative mechanisms (e.g., web-based psychotherapies and use of digital approaches). Patients globally report a good level of acceptability of these interventions. SUMMARY: Depression is a heterogeneous, complex and multidimensional disorder, representing one of the leading causes of disability worldwide. The final aim of the management of patients is functional recovery, which can be achieved by using personalized, integrated and recovery-oriented interventions. Several innovative pharmacological and nonpharmacological treatments are now available; interventions should be selected on the basis of the patient's needs and preferences in order to tailor the treatment, according to a shared decision-making approach.

Promoting mental health and preventing mental health problems in child and adolescent refugees and asylum seekers: A systematic review on psychosocial interventions.

BACKGROUND: According to the United Nations Commissioner for Refugees (UNHCR), children and adolescents represent 41% of all forcibly displaced individuals. They have to deal with conflicts, violence, and the many difficulties of flight and resettlement during a critical stage of their emotional, social, cognitive, and physical development. They are more likely to experience mental health problems during migration. Despite the several known risk factors, it is frequently challenging for refugees and asylum seekers to get mental health care. In this paper we review available studies on interventions aimed at promoting mental health and at preventing common mental disorders in immigrant adolescents and children. METHODS: The relevant PubMed, Scopus, PsychINFO and Web of Science databases were searched for papers published until March 21, 2023, using ("immigrants" OR "migration" OR "asylum seekers" OR "refugees") AND ("promotion" OR "prevention") AND ("mental health" OR "mental disorders" OR "psych*") AND ("children" OR "adolescents" OR "young adults") as search string. Fourteen articles qualified for the detailed review. RESULTS AND CONCLUSIONS: The majority of available interventions, although highly heterogeneous in format and content, showed significant improvement in several psychopathological dimensions, including trauma-related symptoms, psychological stress, anxiety, depressive and cognitive symptoms. Available studies on interventions for the prevention of mental disorders and the promotion of mental health in refugees and asylum seekers children and adolescents indicate that provided interventions were associated with a global improvement for participants. Implementation strategies to improve their scalability are highly needed.

Physical activity influences adherence to pharmacological treatments in patients with severe mental disorders: results from the multicentric, randomized controlled LIFESTYLE trial.

Introduction: Poor adherence to pharmacological treatment is frequent in people with severe mental disorders and it often causes lack of effectiveness of many psychotropic drugs. Thus, efforts should be made to improve adherence to pharmacological treatments in patients with these disorders. Methods: In this paper, based on the LIFESTYLE randomized, controlled multicentric trial, we aim to: 1) assess the level of adherence in a real-world sample of patients with severe mental disorders; 2) evaluate differences in treatment adherence according to patients' socio-demographic and clinical characteristics; 3) evaluate the impact of an innovative psychosocial intervention, on patients' adherence to treatments. The Lifestyle Psychosocial Group Intervention consists of group sessions, focused on different lifestyle behaviours, including healthy diet; physical activity; smoking habits; medication adherence; risky behaviours; and regular circadian rhythms. At end of each session a 20-min moderate physical activity is performed by the whole group. Results: The sample consists of 402 patients, mainly female (57.1%, N = 229), with a mean age of 45.6 years (±11.8). Less than 40% of patients reported a good adherence to pharmacological treatments. Adherence to treatments was not influenced by gender, age, diagnosis and duration of illness. At the end of the intervention, patients receiving the experimental intervention reported a significant improvement in the levels of adherence to treatments (T0: 35.8% vs. T3: 47.6%, p < 0.005). Patients practicing moderate physical activity reported a two-point improvement in the levels of adherence [odds ratio (OR): 1,542; 95% confidence intervals (CI): 1,157-2,055; p < 0.001], even after controlling for several confounding factors. Discussion: The experimental lifestyle intervention, which can be easily implemented in the routine clinical practice of mental health centres, was effective in improving adherence to pharmacological treatments.

Psychosocial interventions for carers of people with severe mental and substance use disorders: a systematic review and meta-analysis.

BACKGROUND: Severe mental disorders - such as schizophrenia, bipolar disorder, and substance use disorders - exert a negative impact not only on affected people but also on their carers. To support carers of people with severe mental disorders, several psychosocial interventions have been developed. METHODS: This systematic review and meta-analysis aimed to assess whether psychosocial interventions for carers of persons with schizophrenia, bipolar disorder, or substance use disorders produce benefit/harm with respect to a series of outcomes - including subjective and objective burden, depressive symptoms, well-being/quality of life, sleep, skills/knowledge, self-efficacy, physical health - as compared to standard support/support as usual or other control conditions. RESULTS: In carers of persons with schizophrenia, psychoeducational interventions were associated with significant improvement in personal burden, well-being, and knowledge about the illness; and a supportive-educational intervention with an improvement in personal burden. In carers of persons with bipolar disorder, psychoeducational interventions were associated with significant improvement in personal burden and depressive symptoms; family-led supportive interventions with an improvement in family burden; family-focused intervention and online "mi.spot" intervention with a significant reduction in depressive symptoms. Psychosocial interventions used for carers of persons with substance use disorders were found to be overall effective on the level of well-being, but the low number of trials did not allow detection of differences between the various psychosocial interventions. CONCLUSIONS: The quality of the evidence ranged from very low to moderate, suggesting the need for further better-quality research.

Biological correlates of treatment resistant depression: a review of peripheral biomarkers.

Introduction: Many patients fail to respond to multiple antidepressant interventions, being defined as "treatment-resistant depression" (TRD) patients. TRD is usually associated with increased severity and chronicity of symptoms, increased risk of comorbidity, and higher suicide rates, which make the clinical management challenging. Efforts to distinguish between TRD patients and those who will respond to treatment have been unfruitful so far. Several studies have tried to identify the biological, psychopathological, and psychosocial correlates of depression, with particular attention to the inflammatory system. In this paper we aim to review available studies assessing the full range of biomarkers in TRD patients in order to reshape TRD definition and improve its diagnosis, treatment, and prognosis. Methods: We searched the most relevant medical databases and included studies reporting original data on possible biomarkers of TRD. The keywords "treatment resistant depression" or "TRD" matched with "biomarker," "inflammation," "hormone," "cytokine" or "biological marker" were entered in PubMed, ISI Web of Knowledge and SCOPUS databases. Articles were included if they included a comparison with healthy controls (HC). Results: Of the 1878 papers identified, 35 were included in the present study. Higher plasma levels of IL-6 and TNF-α were detected in TRD patients compared to HC. While only a few studies on cortisol have been found, four papers showed elevated levels of C-reactive protein among these patients and four articles focused on immunological cells. Altered kynurenine metabolism in TRD patients was reported in two studies, while contrasting results were found with regard to BDNF. Conclusion: Only a few biological alterations correlate with TRD. TNF-α seems to be the most relevant biomarker to discriminate TRD patients from both HC and treatment-responsive MDD patients. Moreover, several discrepancies among studies have been found, due to methodological differences and the lack of a standardized diagnostic definition of TRD.

The predictive role of proinflammatory and neuroendocrine factors in the acute phases of bipolar disorder: study protocol of a longitudinal controlled trial.

INTRODUCTION AND AIMS: Bipolar disorder (BD) is a severe and recurring mental illness associated with a significant personal and social burden. It has been recently hypothesized that increased levels of pro-inflammatory cytokines and cortisol, which is also associated with a reduced expression of the brain-derived neurotrophic factor (BDNF), may influence affective recurrences in BD. Our study aims to: 1) assess changes in the levels of peripheral cytokines, BDNF and salivary cortisol during acute and euthymic phases of bipolar disorder, compared to that of a sample oh healthy controls; 2) evaluate whether these changes represent a biosignature for the different phases of the illness. MATERIALS AND METHODS: Patients aged 18-65 years old, with a diagnosis of BD I or II types, will be enrolled during an acute episode, according to DSM-5 criteria, together with age- and gender-matched healthy controls. Blood and salivary samples will be collected at baseline and after 3 and 6 months. Validated assessment instruments will be administered to all participants for the evaluation of symptom severity, global functioning, suicidal risk, stress levels and physical comorbidities. EXPECTED RESULTS: We expect changes in inflammatory and neuroendocrine indices to be predictive of the onset of an acute phase of bipolar disorder and that overall levels of cytokines, cortisol and BDNF are overall significantly different between BD patients and healthy controls. CONCLUSIONS: The longitudinal design of the study will allow to assess whether the presence of acute affective symptoms in BD patients correlates with significantly higher levels of cytokines and salivary cortisol and with reduced BDNF levels compared to euthymic phases. Moreover, the comparison with healthy control subjects will allow to understand if inflammatory mediators as well as the hypothalamic-pituitary-adrenal (HPA) axis are chronically elevated in BD patients and are independent from mood swings.

Organizational and Individual Interventions for Managing Work-Related Stress in Healthcare Professionals: A Systematic Review.

The workplace represents a relevant source of stress for workers, being a risk factor for many mental disorders and psychological difficulties, including burn-out syndrome. Healthcare workers and other help-professions are particularly susceptible to work-related stress. The present systematic review aims to (1) identify available interventions for managing workplace-related stress symptoms; (2) assess their efficacy; and (3) discuss the current limitations of available interventions. A systematic review has been conducted, searching on PubMed, APA PsycInfo, and Scopus databases. Eighteen papers have been identified, which included different interventions for the management of work-related stress in healthcare professionals. These approaches can be grouped as follows: (1) interventions focusing on the individual level using cognitive-behavioral therapy (CBT) approaches; (2) interventions focusing on the individual level using relaxation techniques; and (3) interventions focusing on the organizational level. As regards interventions targeting the individual level using CBT approaches, mindfulness-based interventions were effective in reducing levels of burn-out, stress, and anxiety and in improving quality of life. As regards intervention using relaxation techniques, including art therapy, Emotional Freedom Techniques (ECT) and brief resilience retreats had a positive effect on the levels of anxiety, stress, and burnout. As regards interventions at the organizational level, we found no evidence for supporting its effectiveness in reducing the levels of burnout. Furthermore, available studies are heterogeneous in terms of assessment tools, target populations, and type of interventions, which limits the generalizability of findings.

Duration of Untreated Illness in Patients with Obsessive-Compulsive Disorder and Its Impact on Long-Term Outcome: A Systematic Review.

Background: Duration of untreated illness (DUI)-defined as the time period between the onset of a mental disorder and its first adequate treatment-should influence patients' long-term prognosis and outcome. In patients with obsessive-compulsive disorder (OCD), DUI lasts on average from 87.5 up to 94.5 months, being significantly longer compared with data available from patients affected by other severe mental disorders, such as schizophrenia and bipolar disorder. We carried out a systematic review in order to assess the impact of DUI on long-term outcomes in OCD patients. Methods: A systemic review has been implemented, searching from inception to April 2023; only papers written in English were included. Results: Seventy-one articles were initially identified; only eight papers were included in the review. The DUI ranged from 7.0 ± 8.5 to 20.9 ± 11.2 years. Patients reporting a longer DUI have a poor long-term outcome in terms of lower level of treatment response and greater symptom severity. Conclusions: The present review confirms that longer DUI has a negative impact on the long-term outcome of patients with OCD. It should be useful to promote the dissemination of early interventions with a specific focus on OCD symptoms.

The Efficacy of Psychoeducational Family Intervention for Major Depression: Study Protocol of a Randomized Controlled Trial.

This study aims to assess the efficacy of a psychoeducational family intervention (PFI) to reduce the severity of depressive symptoms and to improve psychosocial functioning and to increase social contacts in a sample of patients with major depressive disorder (MDD). The degree to which PFI will reduce patients' relapses, hospitalizations, and self-stigmatization and will improve their quality of life will also be assessed. Other secondary outcomes include the improvement of relatives' coping strategies, family burden, expressed emotions and quality of life. This non-profit, unfunded, national, multicentric randomized controlled trial with blinded outcome assessments will be carried out in 24 Italian university outpatient units. Families will be assessed at baseline and at 6, 12, and 24 months post-randomization. Our working hypothesis is that the PFIs will reduce the patients' severity of depressive symptoms, their relapses, and their hospitalizations, and that they will improve their psychosocial functioning and quality of life. We expect these results to be maintained after 12 and 24 months, albeit with a reduction in magnitude. The sample will consist of 384 patients randomized at a 1:1 ratio and stratified according to center, age, gender, and educational level.

Can Brain-Derived Neurotrophic Factor Be Considered a Biomarker for Bipolar Disorder? An Analysis of the Current Evidence.

Brain-derived neurotrophic factor (BDNF) plays a key role in brain development, contributing to neuronal survival and neuroplasticity. Previous works have found that BDNF is involved in several neurological or psychiatric diseases. In this review, we aimed to collect all available data on BDNF and bipolar disorder (BD) and assess if BDNF could be considered a biomarker for BD. We searched the most relevant medical databases and included studies reporting original data on BDNF circulating levels or Val66Met polymorphism. Only articles including a direct comparison with healthy controls (HC) and patients diagnosed with BD according to international classification systems were included. Of the 2430 identified articles, 29 were included in the present review. Results of the present review show a reduction in BDNF circulating levels during acute phases of BD compared to HC, which increase after effective therapy of the disorders. The Val66Met polymorphism was related to features usually associated with worse outcomes. High heterogeneity has been observed regarding sample size, clinical differences of included patients, and data analysis approaches, reducing comparisons among studies. Although more studies are needed, BDNF seems to be a promising biomarker for BD.

The effect of social media and infodemic on mental health during the COVID-19 pandemic: results from the COMET multicentric trial.

On January 30, 2020, the World Health Organization (WHO) declared the status of pandemic due to the COVID-19 infection. The initial phases of the pandemic were characterized by uncertainty and public fears. In order to cope with such unexpected conditions, people adopted different coping strategies, including search for information, accessing Internet, and using social media. The present study based on the COMET collaborative research network aims to: (1) assess use of Internet and of social media among the Italian general population; (2) explore differences in web usage between people with pre-existing mental disorders and the general population; (3) identify changes over time in social media usage along the phase 1 of the pandemic; (4) identify the clinical, socio-demographic and contextual predictors of excessive use of social media. A significant increase in time spent on Internet, with an average time of 4.8 ± 0.02 h per day, was found in the global sample of 20,720 participants. Compared with the general population, Internet use was significantly higher in people with pre-existing mental disorders (5.2 ± 0.1 h vs. 4.9 ± 0.02; p < 0.005). According to the multivariate logistic regression model, the risk of excessive use of social media and Internet was significantly higher in people with moderate levels of depressive symptoms (OR: 1.26, CI 95%: 0.99 to 1.59, p < 0.0.005); while protective factors were being students (OR: 0.72, CI 95%: 0.53 to 0.96, p < 0.0029) and living in central Italy (OR: 0.46, CI 95%: 0.23 to 0.90, p < 0.002). The evaluation of social media and Internet use by the general population represents a first step for developing specific protective and supportive interventions for the general population, including practical suggestions on how to safely use Internet and social media.

The mediating effect of mood spectrum on the relationship between autistic traits and catatonia spectrum.

Background: In the recent years, several studies have shown a correlation between autism spectrum disorder (ASD) and catatonia. It is also known that both conditions are found to be associated with mood disorders. This study aimed to investigate the relationship between autistic traits and catatonic symptoms, as well as the potential mediating role of mood disorder spectrum in the relationship between them. Methods: The total sample of 514 subjects was composed by four diagnostic groups, composed by patients affected by catatonia (CTN), borderline personality disorder (BPD), major depressive disorder (MDD) and healthy controls (HC). Subjects were assessed with the SCID-5-RV, the Adult Autism Subthreshold Spectrum (AdAS Spectrum) and the Catatonia Spectrum (CS) and the Mood Spectrum Self-Report (MOODS-SR). Statistical analyses included Pearson's coefficient calculation, multiple linear regression, and mediation analysis. Results: all the correlations appear to be strongly positive and significant with the strongest coefficient emerging between AdAS Spectrum total score and CS total score (r = 0.762, p < 0.001). The Mediation Analysis showed that AdAS Spectrum total score showed a significant indirect effect on CS total score through MOODS-SR total score (b = 0.168, 95% bootstrapped CI [0.127:0.207]). Conclusion: The present study highlights the presence of a mediating role of the mood disorder spectrum in the relationship between autistic traits and the catatonia spectrum.

Investigating suicidality across the autistic-catatonic continuum in a clinical sample of subjects with major depressive disorder and borderline personality disorder.

Background: Recent literature has highlighted that catatonia may be more prevalent among psychiatric patients than previously thought, beginning from autism spectrum disorders (ASD), for which it has been suggested to represent a severe late consequence, but also among individuals with mood disorders and borderline personality disorder (BPD). Interestingly, one critical point shared by these conditions is the increased risk of suicidality. The aim of this study was to evaluate how the presence and the prevalence of catatonic symptoms may shape and correlate with suicidal risk in a sample of individuals with major depressive disorder (MDD) or BPD. Methods: We recruited two clinical samples of subjects (BPD and MDD) and a control group without a diagnosis according to DSM-5 (CTL). Subjects were assessed with the catatonia spectrum (CS) and the MOODS-SR for evaluating suicidality. Results: In the total sample, suicidality score was significantly and positively correlated with all CS domains and CS total score. Correlation and regression analyses highlighted specific patterns of association among Catatonia spectrum domains and suicidality in the MDD and BPD group and in the total sample. Conclusion: In both disorders, higher catatonic traits are linked to higher suicidal tendencies, confirming the high risk of suicide for this population. However, different patterns of association between catatonic symptoms and suicidality were highlighted in the two disorders.

Autistic traits distribution in different psychiatric conditions: A cluster analysis on the basis of the Adult Autism Subthreshold Spectrum (AdAS Spectrum) questionnaire.

Increasing interest is being paid on full-threshold and sub-threshold autism spectrum conditions among adults. Sub-threshold autistic traits (AT) seem to be distributed in a continuum from the clinical to the general population, being particularly higher among subjects with other psychiatric disorders. The aim of the present study was to evaluate the distribution of AT in a sample of subjects with different psychiatric conditions by means of a cluster analysis on the basis of the score reported to the AdAS Spectrum instrument. A total of 738 subjects recruited by seven Italian Universities were divided in 5 groups depending on the clinical diagnosis: Autism spectrum disorder (ASD), subthreshold ASD symptoms (partial ASD), Bipolar disorder (BD), Feeding and eating disorders (FED), and controls (CTLs). All subjects were assessed with the AdAS Spectrum. The cluster analysis identified 3 clusters: the high, medium and low autism clusters. The Restricted interests and rumination domain reported the highest influence in forming the clusters. The high, medium and low autism clusters were respectively more represented in the ASD, partial ASD and CTL groups. The clusters were represented intermediately in the FED and BD groups, confirming the presence of intermediate levels of AT in these clinical populations.

Effect of affective temperament on illness characteristics of subjects with bipolar disorder and major depressive disorder.

BACKGROUND: Affective temperaments represent the stable, biologically determined substrates of mood disorders. The relationship between affective temperaments and bipolar disorder (BD) or major depressive disorder (MDD) has been described. However, the strength of such relationship should be tested while considering other factors influencing the diagnosis of BD/MDD. Literature also lacks a comprehensive description of the interplay between affective temperament and characteristics of mood disorders. The aim of the present study is to address these issues. METHODS: This is a multicentric observational study including 7 Italian university sites. Five-hundred-fifty-five euthymic subjects with BD/MDD were enrolled and further divided in those with hyperthymic (Hyper, N = 143), cyclothymic (Cyclo, N = 133), irritable (Irr, N = 49), dysthymic (Dysth, N = 155), and anxious (Anx N = 76) temperaments. Linear, binary, ordinal and logistic regressions were performed to assess the association between affective temperaments and i) diagnosis of BD/MDD; ii) characteristics of illness severity and course. RESULTS: Hyper, Cyclo and Irr were more likely to be associated with BD, together with earlier age of onset and presence of a first-degree relative with BD. Anx and Dysth were more associated with MDD. Differences in association between affective temperaments and characteristics of BD/MDD were observed for hospital admissions, phase-related psychotic symptoms, length and type of depression, comorbidity and pharmacological intake. LIMITATIONS: Small sample size, cross-sectional design, recall biases. CONCLUSION: Specific affective temperaments were associated to certain characteristics of illness severity and course of BD or MDD. Evaluation of affective temperaments might help a deeper understanding of mood disorders.
