Anti-Toxin Responses to Natural Enterotoxigenic Escherichia coli (ETEC) Infection in Adults and Children in Bangladesh

A sero-epidemiology study was conducted in Dhaka, Bangladesh between January 2020 and February 2021 to assess the immune responses to ETEC infection in adults and children. (1) Background: Enterotoxigenic Escherichia coli infection is a main cause of diarrheal disease in endemic countries. The characterization of the immune responses evoked by natural infection can guide vaccine development efforts. (2) Methods: A total of 617 adult and 480 pediatric diarrheal patients were screened, and 43 adults and 46 children (below 5 years of age) with an acute ETEC infection completed the study. The plasma samples were analyzed for antibody responses against the ETEC toxins. (3) Results: Heat-stable toxin (ST)-positive ETEC is the main cause of ETEC infection in adults, unlike in children in an endemic setting. We detected very low levels of anti-ST antibodies, and no ST-neutralizing activity. However, infection with ETEC strains expressing the heat-labile toxin (LT) induced systemic antibody responses in less than 25% of subjects. The antibody levels against LTA and LTB, as well as cholera toxin (CT), correlated well. The anti-LT antibodies were shown to have LT- and CT- neutralizing activity. The antibody reactivity against linear LT epitopes did not correlate with toxin-neutralizing activity. (4) Conclusions: Unlike LT, ST is a poor antigen and even adults have low anti-ST antibody levels that do not allow for the detection of toxin-neutralizing activity.

Evaluation of the Safety, Tolerability and Immunogenicity of ShigETEC, an Oral Live Attenuated Shigella-ETEC Vaccine in Placebo-Controlled Randomized Phase 1 Trial

Background: Shigella spp. and enterotoxigenic Escherichia coli (ETEC) cause high morbidity and mortality worldwide, yet no licensed vaccines are available to prevent corresponding infections. A live attenuated non-invasive Shigella vaccine strain lacking LPS O-antigen and expressing the ETEC toxoids, named ShigETEC was characterized previously in non-clinical studies. Methods: ShigETEC was evaluated in a two-staged, randomized, double-blind and placebo-controlled Phase I clinical trial. A single dose of increasing amounts of the vaccine was given to determine the maximum tolerated dose and increasing number of immunizations were administered with an interval based on the duration of shedding observed. Results: Oral immunization with ShigETEC was well tolerated and safe up to 4-time dosing with 5 × 10¹⁰ colony forming units. ShigETEC induced robust systemic immune responses against the Shigella vaccine strain, with IgA serum antibody dominance, as well as mucosal antibody responses evidenced by specific IgA in stool samples and in ALS (Antibodies in Lymphocyte Supernatant). Anti- ETEC toxin responses were detected primarily in the 4-times immunized cohort and for the heat-labile toxin correlated with neutralizing capacity. Conclusion: ShigETEC is a promising vaccine candidate that is scheduled for further testing in controlled human challenge studies for efficacy as well as in children in endemic setting for safety and immunogenicity.

Cerebral cortical thickness and gyrification changes in first-episode psychoses and multi-episode schizophrenia

Cortical thickness (CT) and local gyrification index (LGI) in psychotic disorders may show modifications that relate to clinical course. This observational study aimed to analyse such variables in patients with schizophrenia, compared to healthy controls (HCs). We compared CT and LGI of 18 patients with first-episode psychosis with that of 21 with multi-episode schizophrenia and 16 HCs. CT corrected for false-positive cases (Family-Wise Error Rate) showed a reduction in the multi-episode group compared to HCs in left temporal and parietal, and right temporal, parietal, occipital, and hippocampal cortices. Family-wise corrected LGI was increased in the left inferior and middle frontal cortices, and in the right fusiform gyrus, cingulate, lingual, and parahippocampal gyri in first onset patients compared to HCs. Increased LGI was absent from later stages of psychosis, suggesting that specific CT and LGI alterations may underlie different stages of illness.

Investigation of electrophysiological markers to predict clinical and functional outcome of schizophrenia using sparse partial least square regression

Introduction

Despite innovative treatments, the impairment in real-life functioning in subjects with schizophrenia (SCZ) remains an unmet need in the care of these patients. Recently, real-life functioning in SCZ was associated with abnormalities in different electrophysiological indices. It is still not clear whether this relationship is mediated by other variables, and how the combination of different EEG abnormalities influences the complex outcome of schizophrenia.

Objectives

The purpose of the study was to find EEG patterns which can predict the outcome of schizophrenia and identify recovered patients.

Methods

Illness-related and functioning-related variables were measured in 61 SCZ at baseline and after four-years follow-up. EEGs were recorded at the baseline in resting-state condition and during two auditory tasks. We performed Sparse Partial Least Square (SPLS) Regression, using EEG features, age and illness duration to predict clinical and functional features at baseline and follow up. Through a Linear Support Vector Machine (Linear SVM) we used electrophysiological and clinical scores derived from SPLS regression, in order to classify recovered patients at follow-up.

Results

We found one significant latent variable (p<0.01) capturing correlations between independent and dependent variables at follow-up (RHO=0.56). Among individual predictors, age and illness-duration showed the highest scores; however, the score for the combination of the EEG features was higher than all other predictors. Within dependent variables, negative symptoms showed the strongest correlation with predictors. Scores resulting from SPLS Regression classified recovered patients with 90.1% of accuracy.

Conclusions

A combination of electrophysiological markers, age and illness-duration might predict clinical and functional outcome of schizophrenia after 4 years of follow-up.

Multivariate approach to identify electrophysiological markers for diagnosis and prognosis of schizophrenia

Introduction

Different electrophysiological indices have been investigated to identify diagnostic and prognostic markers of schizophrenia (SCZ). However, these indices have limited use in clinical practice, since both specificity and association with illness outcome remain unclear. In recent years, machine learning techniques, through the combination of multidimensional data, have been used to better characterize SCZ and to predict illness course.

Objectives

The aim of the present study is to identify multimodal electrophysiological biomarkers that could be used in clinical practice in order to improve precision in diagnosis and prognosis of SCZ.

Methods

Illness-related and functioning-related variables were measured at baseline in 113 subjects with SCZ and 57 healthy controls (HC), and after four-year follow-up in 61 SCZ. EEGs were recorded at baseline in resting-state condition and during two auditory tasks (MMN-P3a and N100-P3b). Through a Linear Support Vector Machine, using EEG data as predictors, four models were generated in order to classify SCZ and HC. Then, we combined unimodal classifiers’ scores through a stacking procedure. Pearson’s correlations between classifiers score with illness-related and functioning-related variables, at baseline and follow-up, were performed.

Results

Each EEG model produced significant classification (p < 0.05). Global classifier discriminated SCZ from HC with accuracy of 75.4% (p < 0.01). A significant correlation (r=0.40, p=0.002) between the global classifier scores with negative symptoms at follow-up was found. Within negative symptoms, blunted affect showed the strongest correlation.

Conclusions

Abnormalities in electrophysiological indices might be considered trait markers of schizophrenia. Our results suggest that multimodal electrophysiological markers might have prognostic value for negative symptoms.

Characterization of ShigETEC, a Novel Live Attenuated Combined Vaccine against Shigellae and ETEC

Background: Shigella spp. and enterotoxigenic Escherichia coli (ETEC) remain the two leading bacterial causes of diarrheal diseases worldwide. Attempts to develop preventive vaccines against Shigella and ETEC have not yet been successful. The major challenge for a broad Shigella vaccine is the serotype-specific immune response to the otherwise protective LPS O-antigen. ETEC vaccines mainly rely on the heat-labile enterotoxin (LT), while heat-stable toxin (ST) has also been shown to be an important virulence factor. Methods: We constructed a combined Shigella and ETEC vaccine (ShigETEC) based on a live attenuated Shigella strain rendered rough and non-invasive with heterologous expression of two ETEC antigens, LTB and a detoxified version of ST (ST_N12S). This new vaccine strain was characterized and tested for immunogenicity in relevant animal models. Results: Immunization with ShigETEC resulted in serotype independent protection in the mouse lung shigellosis model and induced high titer IgG and IgA antibodies against bacterial lysates, and anti-ETEC toxin antibodies with neutralizing capacity. Conclusions: ShigETEC is a promising oral vaccine candidate against Shigella and ETEC infections and currently in Phase 1 testing.

Early clinical predictors and correlates of long-term morbidity in bipolar disorder

Objectives:

Identifying factors predictive of long-term morbidity should improve clinical planning limiting disability and mortality associated with bipolar disorder (BD).

Methods:

We analyzed factors associated with total, depressive and mania-related long-term morbidity and their ratio D/M, as %-time ill between a first-lifetime major affective episode and last follow-up of 207 BD subjects. Bivariate comparisons were followed by multivariable linear regression modeling.

Results:

Total % of months ill during follow-up was greater in 96 BD-II (40.2%) than 111 BD-I subjects (28.4%; P = 0.001). Time in depression averaged 26.1% in BD-II and 14.3% in BD-I, whereas mania-related morbidity was similar in both, averaging 13.9%. Their ratio D/M was 3.7-fold greater in BD-II than BD-I (5.74 vs. 1.96; P < 0.0001). Predictive factors independently associated with total %-time ill were: [a] BD-II diagnosis, [b] longer prodrome from antecedents to first affective episode, and [c] any psychiatric comorbidity. Associated with %-time depressed were: [a] BD-II diagnosis, [b] any antecedent psychiatric syndrome, [c] psychiatric comorbidity, and [d] agitated/psychotic depressive first affective episode. Associated with %-time in mania-like illness were: [a] fewer years ill and [b] (hypo)manic first affective episode. The long-term D/M morbidity ratio was associated with: [a] anxious temperament, [b] depressive first episode, and [c] BD-II diagnosis.

Conclusions:

Long-term depressive greatly exceeded mania-like morbidity in BD patients. BD-II subjects spent 42% more time ill overall, with a 3.7-times greater D/M morbidity ratio, than BD-I. More time depressed was predicted by agitated/psychotic initial depressive episodes, psychiatric comorbidity, and BD-II diagnosis. Longer prodrome and any antecedent psychiatric syndrome were respectively associated with total and depressive morbidity.

Alexithymia and Coping Strategies: Predictors of Hopelessness?

Introduction

Alexithymic traits and coping strategies may affect the onset and course of many psychiatric conditions. However, their role in determining hopelessness and suicide risk has been not still elucidated.

Objectives

The present study analyzed the correlations between alexithymia, coping strategies, and hopelessness.

Aims

We aimed to evaluate whether specific coping strategies and alexithymia may predict hopelessness which is widely considered an independent risk factor for suicide.

Methods

This is a cross-sectional study conducted on 276 patients (19.9% men, 81.1% women; mean age: 48.1 years, SD: 16.9), of which most with major affective disorders, who were admitted at the Psychiatric Unit of the University of Genoa (Italy). All participants were assessed using the Beck Hopelessness Scale (BHS), Coping Orientations to Problems Experienced (COPE), and Toronto Alexithymia Scale (TAS-20).

Results

Alexythimic subjects significantly differ from non-alexythimic individuals in terms of substance abuse (χ2 = 23.1; P = .027). According to bivariate analyses, we found a significant correlation between hopelessness and suicidal thoughts/wishes (r = .34; P = .01), humor (r = –.24; P = .05), and behavioural disengagement (r = .205; P = .05). Behavioural disengagement is also a positive predictor of hopelessness (OR = 1.25; 95% CI: 1.03–1.52) while humour is a negative predictor of hopelessness (OR = 0.85; 95% CI: 0.73–0.99).

Conclusions

Behavioural disengagement needs to be considered a risk factor while humor is a protective factor for suicide. Surprisingly, we found no significant association between alexithymia and hopelessness. Further additional studies are requested to test these exploratory findings in order to more deeply elucidate the role of both alexithymia and coping strategies in suicidal behaviour.

Clinical and neurocognitive characteristics associated with treatment-resistant depression

Introduction

Treatment resistant depression (TRD) is a disabling condition associated with a relevant psychosocial impairment worldwide.

Objectives

This exploratory study is aimed to evaluate the main clinical and neurocognitive characteristics in a sample of 21 subjects admitted to the Psychiatric Clinic of University of Genoa as inpatients between 2015 and 2016 and diagnosed with TRD according to Thase and Rush staging method.

Methods

Patients have been assessed using the Hamilton Depression Rating Scale (HDRS), Hamilton Anxiety Rating Scale, and Clinical Global Impression (CGI). The Continuous Performance Test (CPT), Trial Making Test (TMT-A/B), Stroop Color Word Interference Test, Verbal Fluency Test, and Rey auditory-verbal learning test (RAVLT) have been administered as well.

Results

Subjects with early-onset (< 50 years) depression had a longer illness duration, higher depressive episodes and more impaired performance at RAVLT while individuals with late-onset (> 50 years) depression showed a higher severity of depressive symptoms and more anxiety symptoms. Depressive symptoms were positively associated with anxiety (r = 0.82; P = 0.00) and negatively with TMT-A/B (r = −0.56, P = 0.01), Stroop Color Word Interference Test (r = −0.72, P = 0.005 and r = −0.616, P = 0.008), and RAVLT (r = −0.60; P = 0.02) performances. According to regression analyses, anxiety symptoms were the only significant predictor of depression severity (P = 0.02).

Conclusions

Early-onset depression is associated with more disability and worse neurocognitive performance whereas late-onset depression is linked to more anxiety symptoms and more depressive symptoms severity. Clinicians should closely monitor patients with TRD for the presence of anxiety symptoms that may represent a significant risk factor of poorer long-term outcome.

Deficits in Mentalization Predict Suicide Risk Among Psychiatric Inpatients

Introduction

Suicide is a major public health issue.

Objectives

Mentalization is a form of imaginative mental activity about others or oneself that may shed light on the phenomenology of suicide.

Aims

To assess the role of a number of variables in suicide risk.

Methods

Participants were 156 (73 men and 83 women) adult psychiatric inpatients (age range = 18/74 year). Most of the patients had a major mood disorder (26.3% BD-I, 3.2% BD-II, and 11.5 MDD), psychosis (16.7%), or a schizoaffective disorder (20.5%). All the patients were administered the Mini International Neuropsychiatric Interview (MINI) for assessing diagnosis and suicide risk, and the Impact of event scale, Mentalization Questionnaire, Childhood Trauma Questionnaire. Some patients (18.6%) were admitted for a recent suicide attempt and 34.6% had attempted suicide in the past.

Results

At the MINI, 44.9% of the patients resulted at a moderate to high risk of suicide, and 55.1% at no or low risk of suicide with no difference for sociodemographic variables (sex and age) and diagnosis, but they differed for mentalization and symptoms of intrusions and avoidance caused by a traumatic event. Groups also did not differ for self-reported childhood trauma. Only mentalization was independently associated with higher suicide risk, and patients with moderate to severe risk of suicide were 1.7 times more likely to report more mentalization deficits than those with no or low risk of suicide.

Conclusions

Our study supports the notion that the investigation of mentalization among patients may help in proper assessment of suicide risk.

Premorbid academic and social functioning in patients with schizophrenia and its associations with negative symptoms and cognition

OBJECTIVE

The study aimed to explore premorbid academic and social functioning in patients with schizophrenia, and its associations with the severity of negative symptoms and neurocognitive impairment.

METHOD

Premorbid adjustment (PA) in patients with schizophrenia was compared to early adjustment in unaffected first-degree relatives and healthy controls. Its associations with psychopathology, cognition, and real-life functioning were investigated. The associations of PA with primary negative symptoms and their two factors were explored.

RESULTS

We found an impairment of academic and social PA in patients (P ≤ 0.000001) and an impairment of academic aspects of early adjustment in relatives (P ≤ 0.01). Patients with poor PA showed greater severity of negative symptoms (limited to avolition after excluding the effect of depression/parkinsonism), working memory, social cognition, and real-life functioning (P ≤ 0.01 to ≤0.000001). Worse academic and social PA were associated with greater severity of psychopathology, cognitive impairment, and real-life functioning impairment (P ≤ 0.000001). Regression analyses showed that worse PA in the academic domain was mainly associated to the impairment of working memory, whereas worse PA in the social domain to avolition (P ≤ 0.000001).

CONCLUSION

Our findings suggest that poor early adjustment may represent a marker of vulnerability to schizophrenia and highlight the need for preventive/early interventions based on psychosocial and/or cognitive programs.

Neural functional correlates of emotional processing in patients with first-episode psychoses: an activation likelihood estimation (ALE) meta-analysis

BACKGROUND

Early emotional recognition impairment characterises rst-episode psychoses (FEP) and remains stable thereafter. Patients with FEP consistently show brain activation changes during emotional processing in functional neuroimaging studies.

AIM AND METHODS

To identify and compare cerebral activation correlates of FEP patients and healthy controls (HCs) during emotional task performances, we performed an Activation Likelihood Estimation (ALE) meta-analysis of peer-reviewed functional magnetic resonance imaging (fMRI) studies.

RESULTS

Five studies included 71 patients with FEP and 75 HCs. Within-group analyses showed that HCs activated during emotional task performance the bilateral inferior parietal lobule (BAs 39 and 40), left inferior frontal gyrus (BAs 9 and 47), right amygdala, left middle frontal gyrus (BA 9), right cingulate gyrus (BA 32), and right middle temporal gyrus (BA 21). FEP activations correlating with emotional tasks included the right cuneus (BA 17) and right angular gyrus (BA 39).

CONCLUSIONS

During emotional task performance, FEP patients fail to activate an extensive brain network comprising emotional processing-related areas, including both cortical and subcortical areas.

Interpersonal sensitivity and persistent attenuated psychotic symptoms in adolescence

Interpersonal sensitivity defines feelings of inner-fragility in the presence of others due to the expectation of criticism or rejection. Interpersonal sensitivity was found to be related to attenuated positive psychotic symptom during the prodromal phase of psychosis. The aims of this study were to examine if high level of interpersonal sensitivity at baseline are associated with the persistence of attenuated positive psychotic symptoms and general psychopathology at 18-month follow-up. A sample of 85 help-seeking individuals (mean age = 16.6, SD = 5.05) referred an Italian early detection project, completed the interpersonal sensitivity measure and the structured interview for prodromal symptoms (SIPS) at baseline and were assessed at 18-month follow-up using the SIPS. Results showed that individuals with high level of interpersonal sensitivity at baseline reported high level of attenuated positive psychotic symptoms (i.e., unusual thought content) and general symptoms (i.e., depression, irritability and low tolerance to daily stress) at follow-up. This study suggests that being "hypersensitive" to interpersonal interactions is a psychological feature associated with attenuated positive psychotic symptoms and general symptoms, such as depression and irritability, at 18-month follow-up. Assessing and treating inner-self fragilities may be an important step of early detection program to avoid the persistence of subtle but very distressing long-terms symptoms.

Efficacy of the “Cooperative Assessment” Diagnostic Procedure to Early Improve Acute Symptoms in a Sample of Adolescents with Anxiety and Mood Disorders

Introduction

Anxiety and mood disorders are common in adolescence and predict poor mental health outcomes and low quality of life in adulthood. Although early intervention seems to be critical, dropouts in the early stages of treatment are frequent and associated with low insight and severe symptoms. Therefore, a diagnostic assessment phase aimed to increase insight and early reduce symptoms appears to be essential in adolescents.

Objectives

The objective of this study is to demonstrate that the diagnostic method Cooperative Assessment is able to early reduce symptoms in adolescents with anxiety and mood disorders.

Methods

A sample of 88 patients, aged 14–19 years were included. All were recruited at the first visit and evaluated with the Cooperative Assessment. This manualized procedure was created from principles of collaborative and therapeutic assessment and aim to involve the patient in a co-developed diagnosis thorough the collaborative use of test results. Patients were evaluated before (T0), in the middle (T1) and after (T2) the assessment using CGI, GAF, HAM-A, HAM-D and MRS scales.

Results

Eighty-eight adolescents, 56.8% females, diagnosed with anxiety (47.7%) and mood disorders (52.3%) completed the protocol. HAM-A, HAM-D, MRS, CGI and GAF significantly improved at T1 and T2 with respect to T0 (T0: HAM-A 17.31 ± 8.22; HAM-D 16.97 ± 8.37; MRS5.78 ± 6.17; GAF 59.3 ± 11.06; CGI 3.63 ± 1.35; T2: HAM-A 11.41 ± 6.82; HAM-D 11.1 ± 6.91; MRS3.82 ± 3.87; GAF 67.5 ± 10.76; CGI 3.03 ± 1.26; P < 0.001; Wilcoxon signed-rank test for repeated measures).

Conclusions

Cooperative assessment is able to early improve symptoms in adolescents with mood and anxiety disorders.

Risperidone-treated Children and Adolescents with Behavioral Disorders: Do Drug Dose and Patients’ Gender and Age Relate to Drug and Metabolite Plasma Levels?

Introduction

Behavioral disorders, such as conduct disorder, influence choice of treatment and its outcome. Less is known about other variables that may have an influence.

Objectives/Aims

We aimed to measure the parent drug and metabolite plasma levels in risperidone-treated children and adolescents with behavioral disorders and investigate the role of drug dose and patients’ gender and age.

Methods

We recruited 115 children/adolescents with DSM-5 behavioral disorders (females = 24; age range: 5–18 years) at the Departments of Psychiatry of the Hospitals of Bolzano, Italy, and Innsbruck, Austria. We measured risperidone and its metabolite 9-hydroxyrisperidone plasma levels and the parent drug-to-metabolite ratio in the plasma of all patients by using LC-MS/MS. A subsample of 15 patients had their risperidone doses measured daily. We compared risperidone and 9-hydroxyrisperidone plasma levels, as well as risperidone/9-hydroxyrisperidone ratio, in males vs. females and in younger (≤ 14 years) vs. older (15–18 years) patients by using Mann-Whitney U test. We fitted linear models for the variables “age” and “daily risperidone dose” by using log-transformation, regression analysis and applying the R2 statistic.

Results

Females had significantly higher median 9-hydroxyrisperidone plasma levels (P = 0.000). Younger patients had a slightly lower median risperidone/9-hydroxyrisperidone ratio (P = 0.052). At the regression analysis, daily risperidone doses and metabolite, rather than parent drug–plasma levels were correlated (R2 = 0.35).

Conclusions

Gender is significantly associated with plasma levels, with females being slower metabolizers than males. Concerning age, younger patients seem to be rapid metabolizers, possibly due to a higher activity of CYP2D6. R2 suggests a clear-cut elimination of the metabolite.

Economic Aspects in the Treatment of Schizophrenia in Italy: Cost Consequences of an Early Long-acting Injectable Anti-Psychotics (lais) Approach

Purpose

The aim of this analysis was to evaluate the economic consequences of a new treatment approach in the treatment of schizophrenia in the Italian setting. In terms of direct costs, in Italy was estimated that the main driver were represented by hospitalization and residential cost (71% of total direct cost per patient), followed by semi-residential services (13%), anti-psychotic and other drugs (8%) and ambulatory services (8).

Methods

A probabilistic cost consequence model was developed to estimate the potential cost reductions derived from an early treatment with atypical long-acting injectable anti-psychotics (aLAIs) drugs. A systematic literature review was carried out to identify direct and indirect costs associated to the management of schizophrenic patients in Italy. The model projects a scenario analysis in order to estimate potential cost reductions applying a new model management (MoMa) based on patient recovery and early aLAIs treatment.

Results

Overall, the total economic burden associated with schizophrenia was estimated at €2.7 billion per year. A total of 50.5% of the economic burden was related to indirect costs and 49.5% to direct costs. Drug costs correspond to 10% of the total expenditure in terms of direct costs, while hospitalization and residential costs accounts for 81%. Scenario analysis demonstrate a potential cost reduction between 200 million and 300 million based on the effects of MoMa over the reduction of hospitalization and residential costs.

Conclusions

This analysis was the first attempt to translate clinical management aspects in economic consequences and will be a useful instruments for decision maker.

Suicide and drug and alcohol addiction: Self-destructive behaviours. An observational study on clinic hospital population

Introduction

Suicidal behaviour and drug and alcohol dependence represent two different aspects of self-destructive behavior.

Objectives

We evaluated the relationship between suicidal behavior and substance and alcohol addiction. It was investigated the role of childhood trauma in these self-destructive behaviors and in the development of the two mental constructions of hopelessness and mentalization.

Aims

We also assessed how a high level of hopelessness could affect suicidal ideation and how low or absent capacity of mentalization could influence the development of substance and/or alcohol addiction.

Methods

This naturalistic, observational study included 50 patients (mean age = 46.54; S.D = 14.57) recruited from the department of psychiatry (n = 18) and the centre for suicide prevention (n = 32) of Sant’Andrea Hospital (Rome). Different questionnaires were administered to each patient from February to May 2016.

Results

There was not a statistically significant relationship between suicidal behavior and addict behavior. Childhood trauma resulted a risk factor for alcohol abuse with a relationship that tended to significance (P = 0.07). Physical and sexual abuses were significantly associated with addiction (respectively P = 0.014; P = 0.033). It was showed a statistically significant interaction between high level of hopelessness and suicidal ideation (P = 0.037). The absence of mentalization was related to the absence of alcohol abuse (P = 0.061). Finally, trauma experienced during childhood was associated with high level of hopelessness (P = 0.005).

Conclusions

Suicidal behavior is influenced indirectly by a childhood traumatic experience that conditioning the level of hopelessness. Childhood trauma affected directly the development of drug abuse and alcoholism. The capacity of mentalization was not related with childhood trauma.

Sensitivity and specificity of the Italian version of the bipolar spectrum diagnostic scale. Different scores in distinct populations with unipolar depression

Introduction

To date, the proposition of recurrence as a subclinical bipolar disorder feature has not received adequate testing.

Objectives/Aims

We used the Italian version of the bipolar spectrum diagnostic scale (BSDS), a self-rated questionnaire of bipolar risk, in a sample of patients with mood disorders to test its specificity and sensitivity in identifying cases and discriminating between high risk for bipolar disorder major depressive patients (HRU) and low risk (LRU) adopting as a high recurrence cut-off five or more lifetime major depressive episodes.

Methods

We included 115 patients with DSM-5 bipolar disorder (69 type I, 41 type II, and 5 NOS) and 58 with major depressive disorder (29 HRU and 29 LRU, based on the recurrence criterion). Patients filled-out the Italian version of the BSDS, which is currently undergoing a validation process.

Results

The BSDS, adopting a threshold of 14, had 84% sensitivity and 76% specificity. HRU, as predicted, scored on the BSDS intermediate between LRU and bipolar disorder. Clinical characteristics of HRU were more similar to bipolar disorder than to LRU; HRU, like bipolar disorder patients, had more lifetime hospitalizations, higher suicidal ideation and attempt numbers, and higher rates of family history of suicide.

Conclusions

The BSDS showed satisfactory sensitivity and sensitivity. Splitting the unipolar sample into HRU and LRU, on the basis of the at least 5 lifetime major depressive episodes criterion, yielded distinct unipolar subpopulations that differ on outcome measures and BSDS scores.

Childhood Traumatic Experiences and Coping Strategies: Correlations With Quality of Life

Introduction

Individuals with a history of childhood traumatic experiences may exert maladaptive coping strategies and impaired adult quality of life.

Objectives

The present study explored the association between childhood traumatic experiences, coping strategies, and quality of life.

Aims

We aimed to evaluate whether childhood traumatic experiences or specific coping strategies may significantly predict quality of life.

Methods

This is a cross-sectional study including 276 patients (19.9% men, 81.1% women; mean age: 48.1 years, SD: 16.9), of which most with major affective disorders, who were recruited at the psychiatric unit of the university of Genoa (Italy). All participants were assessed using the Childhood Trauma Questionnaire (CTQ), Coping Orientation to Problems Experienced (Cope), and Short Form 12 Health Survey version 2 (SF-12).

Results

Subjects with a history of emotional abuse were more likely to have an earlier age of onset of their psychiatric conditions, an earlier age of their first treatment/hospitalization, higher recurrent episodes and days of hospitalization, longer illness duration and non-psychiatric treatments at intake when compared with those who did not present any history of abuse. Based on regression analyses, only positive reinterpretation and growth, focus on and venting of emotions, and substance abuse, but not childhood traumatic experiences, resulted positive predictors of physical quality of life. Moreover, focus on and venting of emotions was able to predict mental quality of life.

Conclusions

While traumatic experiences did not predict quality of life, specific coping strategies were significant predictors of quality of life. Further studies are requested to test these preliminary results.

Assessment of Suicide-related Knowledge and Skills in a Sample of Health Professionals and Students

Objective

Assessment of suicide risk is of paramount importance for proper prevention.

Aims

To examine the association between gatekeeper training and suicide-related knowledge among a diverse set of health care workers (psychiatrists, nurses, psychologists, and educators) and students enrolled in medical and psychological schools who took part in the world suicide prevention day 2015 conference.

Method

Among 223 participants who completed the assessment, 204 provided complete data for analyses. Participants were administered the applied suicide intervention skills training (ASIST), a 13-item survey questionnaire to assess participants’ knowledge about suicidal behavior and comfort dealing with suicidal clients. There were 62 psychiatrists; 23 nurses, 51 psychologists, 11 educators, and 57 university students.

Results

Among participants, 57.1% of the sample had experiences of suicide a patient (students were excluded from these analyses). Those who reported a suicide among patients (compared with others) less frequently answered that suicide risk is more alarming in older adults than youths. They also less frequently disagreed with questions asking if they had the training to deal with suicidal patients. Students more frequently answered correctly on the association between depression and suicide risk, and less frequently chose the correct answer on the seriousness of suicide intent in borderline personality disorder. Students also more frequently disagreed with questions asking on their suicide assessment skill.

Conclusions

Our study highlights that differences exist when it comes to knowledge and skills related to suicide risk assessment both among health professionals and students. Our results also indicate that suicide awareness among these groups should be promoted.

Neural functional correlates of empathic face processing: An activation likelihood estimation (ALE) meta-analysis of fMRI studies

Introduction

Empathy is evolutionary preserved in social organisms and emotional face processing is one of its measures. Systems possibly active during empathic processing include perspective-taking, basic emotional contagion “mirroring” and “theory of mind” systems.

Objectives

fMRI studies help clarifying neural correlates of empathic face processing; ALE meta-analysing fMRI studies allows identification of brain area activation/deactivation during empathy.

Aims

To identify brain areas most consistently involved in empathy.

Methods

We carried ALE meta-analysis of original studies focusing on cerebral activations during empathic face processing tasks and reporting data on Talairach or MNI space coordinates, converting the former in the latter. An 11-April-2016 PubMed search, using as keywords terms like empathy combined with functional magnetic resonance imaging (fMRI), produced 124 records of which 23 were finally included (568 participants, 247 males and 321 females; mean age 32.2 years). We followed the PRISMA statement. Whole-brain data were meta-analysed; significance was set at P = 0.0001, uncorrected.

Results

ALE meta-analysis of data from 21 experiments (totalling 527 foci) on empathic face processing during experimental task conditions showed that emotional vs. neutral/control conditions significantly correlated with activations of left anterior cingulate cortex (BA 32), right precentral gyrus (BA 6), left amygdala, right superior frontal gyrus (BA 9), left middle occipital gyrus (BA 37), right insula (BA 13), left putamen, and left posterior cingulate cortex (BA 31).

Conclusions

Empathy is a complex process correlating with activation of different brain areas, which have been involved in emotional cue processing, self-other/same-different discrimination, perspective-taking, mirror neuron activation, emotional arousal and decision-making.

Methylphenidate challenge followed by therapeutic drug monitoring in adults with attention deficit/hyperactivity disorder: Clinical effects and its predictors

Introduction

Attention deficit/hyperactivity disorder (ADHD) affects 5–6% of adults. Methylphenidate challenge is used to test functions such as concentration. Therapeutic drug monitoring (TDM) identifies optimal drug ranges in plasma.

Objectives/Aims

We aimed to: assess the clinical impact of the drug challenge in adults with ADHD; analyze the relationship with the drug plasma levels after the challenge; identify predictors of the challenge's clinical impact.

Methods

In 2015–2016, we recruited 45 consecutive adult DSM-5 ADHD outpatients (mean age ± SD = 35.3 ± 2.1 years; females = 64.4%) at the Bolzano hospital department of psychiatry. Before and after administration of methylphenidate 10 mg, we measured concentration, impulsivity, tension, and general well-being with a VAS and an interview. After two hours, TDM was performed. Deltas were calculated for pre-/post-challenge measures. Correlations were measured with Pearson's r/point-biserial coefficient. A generalized linear mixed model estimated the size of association between tension/general well-being improvement and patient characteristics.

Results

After the challenge, the mean improvement ± SD was 24 ± 22 for concentration, 17 ± 23 for impulsivity, 21 ± 28 for tension, 16 ± 24 for general well-being. The mean TDM ± SD was 4.6 ± 0.5 ng/mL. A negative correlation between TDM, tension (P = 0.009), and general well-being (P = 0.028) after the challenge emerged: higher drug plasma levels relate to less tension and greater general well-being. At the GLMM the main predictor for tension/general well-being improvement was psychopharmacological treatment (P = 0.011/P = 0.05, respectively). Older age and difficult tasks prevented improvement.

Conclusions

Methylphenidate challenge had a positive effect on all patients’ performance. TDM values were lower than literature ones, although the latter are usually obtained after the administration of methylphenidate 20 mg.

Social cognition in people with schizophrenia: a cluster-analytic approach

BACKGROUND

The study aimed to subtype patients with schizophrenia on the basis of social cognition (SC), and to identify cut-offs that best discriminate among subtypes in 809 out-patients recruited in the context of the Italian Network for Research on Psychoses.

METHOD

A two-step cluster analysis of The Awareness of Social Inference Test (TASIT), the Facial Emotion Identification Test and Mayer-Salovey-Caruso Emotional Intelligence Test scores was performed. Classification and regression tree analysis was used to identify the cut-offs of variables that best discriminated among clusters.

RESULTS

We identified three clusters, characterized by unimpaired (42%), impaired (50.4%) and very impaired (7.5%) SC. Three theory-of-mind domains were more important for the cluster definition as compared with emotion perception and emotional intelligence. Patients more able to understand simple sarcasm (⩾14 for TASIT-SS) were very likely to belong to the unimpaired SC cluster. Compared with patients in the impaired SC cluster, those in the very impaired SC cluster performed significantly worse in lie scenes (TASIT-LI <10), but not in simple sarcasm. Moreover, functioning, neurocognition, disorganization and SC had a linear relationship across the three clusters, while positive symptoms were significantly lower in patients with unimpaired SC as compared with patients with impaired and very impaired SC. On the other hand, negative symptoms were highest in patients with impaired levels of SC.

CONCLUSIONS

If replicated, the identification of such subtypes in clinical practice may help in tailoring rehabilitation efforts to the person's strengths to gain more benefit to the person.

The communication of suicidal intentions: a meta-analysis

BACKGROUND

Among the myths that are often cited about suicide is that 'people who talk about killing themselves rarely die by suicide', but the evidence seems to contradict this statement. The aim of this study was to conduct a meta-analysis of studies reporting a prevalence of suicide communication (SC), and to examine the diagnostic accuracy of SC towards suicide in case-control reports.

METHOD

Eligible studies had to examine data relative to completed suicides and report the prevalence of SC. Data relative to sample characteristics, study definition, modality and recipient of the SC were coded.

RESULTS

We included 36 studies, conducted on a total of 14 601 completed suicides. The overall proportion of SC was 44.5% [95% confidence interval (CI) 35.4-53.8], with large heterogeneity (I 2 = 98.8%) and significant publication bias. The prevalence of SC was negatively associated with the detection of verbal communication as the sole means of SC and, positively, with study methodological quality. Based on seven case-control studies, SC was associated with an odds ratio of 4.66 for suicide (95% CI 3.00-7.25) and was characterized by sufficient diagnostic accuracy only if studies on adolescents were removed.

CONCLUSION

Available data suggest that SC occurs in nearly half of subjects who go on to die by suicide, but this figure is likely to be an underestimate given the operational definitions of SC. At present, SC seems associated with overall insufficient accuracy towards subsequent suicide, although further rigorous studies are warranted to draw definite conclusions on this issue.

Severity of traumatic events in patients with eating disorders. A case-control study

Introduction

A high proportion of individuals with eating disorders (EDs) report childhood abuse and neglect. The prevalence of traumatic events in ED patients has been extensively investigated; less is known about their self-perceived–and reported–severity. Objectives/Aims: We aimed to assess in ED patients vs. healthy controls the severity, i.e., duration, perpetrator, and subjective impact, of sexual, physical, and emotional traumas suffered from 0 to 18 years, paying particular attention to emotional neglect.

Methods

Fifty-seven consecutive DSM-V ED patients (91.2% females; age range: 18–42 years) were recruited at the Psychiatric Outpatient Clinic of our University Hospital. Ninety controls (78.9% females; age range: 20–39 years) were also recruited. Among ED patients, 43.9% had restrictive anorexia nervosa (AN), 29.8% binge/purging AN, 26.3% bulimia nervosa. Individuals completed the Eating Disorder Inventory-2 (EDI-2) and the Traumatic Experiences Checklist (TEC).

Results

The severity of all traumatic events, according to the TEC total score, was significantly higher in ED patients than controls (P < 0.001). Moreover, ED patients showed significantly higher scores with regard to emotional neglect (P < 0.001) and emotional abuse (P < 0.001). The same can be said for physical traumas (P < 0.01) and physical abuse (P < 0.01), although with a lower significance, and for sexual abuse (P < 0.05), with an even lower significance. No difference in the severity of sexual harassment was found.

Conclusions

All types of traumas, especially neglect, can occur in ED patients and controls, however they are reported as more severe by ED patients.

Emotional neglect as the colossus among traumas in patients with eating disorders. A case-control study

Introduction

Individuals with eating disorders (EDs) often report a history of early traumatization. Although a great attention has been paid to sexual and physical trauma, less is known about emotional one, especially neglect.

Objectives/aims

We aimed to estimate the prevalence of sexual, physical, and emotional trauma–occurring under 18 years of age–in ED patients vs. healthy controls, focusing on emotional abuse and neglect.

Methods

We consecutively recruited 57 DSM-V ED outpatients (91.2% females; age range = 18–42 years) at the Psychiatric Outpatient Clinic of our University Hospital and 90 healthy controls (78.9% females; age range = 20–39 years). Among ED patients, 43.9% had restrictive anorexia nervosa (AN), 29.8% binge/purging AN, 26.3% bulimia nervosa. Individuals completed the Eating Disorder Inventory-2 (EDI-2) and the Traumatic Experiences Checklist (TEC). We used Mann-Whitney U test and χ2 test for comparisons.

Results

ED patients scored significantly higher than controls on all EDI-2 subscales (P-values < 0.05). On the TEC, emotional trauma was more frequent than sexual/physical ones in both ED patients and controls. Emotional trauma, and to a lesser extent physical one, were significantly more frequent in ED patients than controls. Distinguishing between emotional abuse and neglect, the latter had a higher prevalence than the former in both groups. Additionally, ED patients reported significantly more neglect, but not emotional abuse, than controls.

Conclusions

Our findings show a high prevalence of emotional trauma in EDs, mainly neglect, i.e., a lack of care and attention potentially contributing to EDs. Thus, it is crucial to investigate emotional neglect in ED patients.

Kynurenine pathway metabolites and suicide attempters among psychiatric inpatients: Preliminary results

Introduction

Increased concentrations of kynurenine (KYN) pathway metabolites have been associated to several groups of psychiatric disorders. As for suicide risk literature is still inconclusive due to the limited evidence.

Objectives

to test the hypothesis of Increased concentrations of kynurenine as related to suicide attempter.

Aims

We aim to investigate the association between kynurenine pathway metabolites blood levels and suicidal behaviour, in affective disorder patients, in order to explore if kynurenine pathway metabolites could be potential diagnostic biomarkers.

Sample

We enrolled a sample of affective disorder patients and perform detailed diagnoses, as well as detailed assessment of suicidal behaviour using validated questionnaires. We also aim to follow-up individuals included in the current study.

Methods

Plasma KYN was assayed by high performance liquid chromatography in three groups: healthy volunteers (n = 90), patients with mood disorders with a recent suicide attempt (n = 44) and without (n = 44) history of suicide attempt. Analysis of variance tested for group differences in KYN levels. Each was evaluated with psychometric scales. Patients were sampled for 10 cc of venous blood for assay. The preparation of blood samples and assay was processed by a specialist using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS).

Results

Preliminary results will be presented as to shed light if KYN levels differed across groups. According to preliminary calculations we expect that KYN is higher in suicide attempters compared with non-attempters, who did not differ from healthy volunteers.

Conclusions

Our work-in-progress study suggests that KYN and related molecular pathways may be implicated in the precipitation of suicidal behavior.

Psychopathology, temperament and suicide risk in adolescence: The role of early traumatic experience

Introduction

Previous researches showed that adolescents are at high risk of suicide. Suicide is a trans-nosographic phenomenon regardless of psychiatric diagnosis. Trauma is an important risk factor for suicide and young help-seeking patients usually refer traumatic experiences, especially during childhood.

Objectives

The objective of this study is to assess the relationship between traumatic experience and suicide risk comparing adolescents with suicide risk with adolescents without suicide risk.

Aims

To investigate correlations between trauma, psychopathology and suicide risk in a sample of young help-seeking outpatients.

Methods

We recruited 99 outpatients aged between 14 and 21 years admitted to department for prevention and early intervention in adolescence of Rome. We administered psychometric instruments exploring suicide risk (SHSS, BHS), prodromal (SIPS/SOPS), affective and anxious symptoms (HAM-A, HAM-D,MRS), child abuse (CTQ) and experiences of depersonalization (CDS).

Results

Sample is composed of 31 men and 68 women. A total of 34.3% had mood disorder. A total of 28.3% reported history of emotional neglect, 20.2% emotional abuse, 9.15 sexual abuse, 5.1% physical neglect, 9,1% sexual abuse, 4% physical abuse. More than 30% of patients were at increased suicide risk. Depressive, irritable, anxious and cyclothymic temperament was associated with suicide risk. Patients with suicide risk had higher score at HAM-D (t63 = 2.65; P = 0.01), CDS (t63 = 2.77; P = 0.007), in CTQ (t63 = 3.20; P = 0.002) and BHS (t63 = 3.23; P = 0.002).

Conclusions

Adolescents with suicide risk, compared with those without, reported more frequently early traumatic experiences and psychiatric symptoms. Early traumatic experiences constitute a risk factor for both suicide risk and psychiatric symptoms during adolescence.

Effect of high-potency cannabis on corpus callosum microstructure

BACKGROUND

The use of cannabis with higher Δ9-tetrahydrocannabinol content has been associated with greater risk, and earlier onset, of psychosis. However, the effect of cannabis potency on brain morphology has never been explored. Here, we investigated whether cannabis potency and pattern of use are associated with changes in corpus callosum (CC) microstructural organization, in patients with first-episode psychosis (FEP) and individuals without psychosis, cannabis users and non-users.

METHOD

The CC of 56 FEP (37 cannabis users) and 43 individuals without psychosis (22 cannabis users) was virtually dissected and segmented using diffusion tensor imaging tractography. The diffusion index of fractional anisotropy, mean diffusivity (MD), axial diffusivity (AD) and radial diffusivity was calculated for each segment.

RESULTS

Across the whole sample, users of high-potency cannabis had higher total CC MD and higher total CC AD than both low-potency users and those who never used (p = 0.005 and p = 0.004, respectively). Daily users also had higher total CC MD and higher total CC AD than both occasional users and those who never used (p = 0.001 and p < 0.001, respectively). However, there was no effect of group (patient/individuals without psychosis) or group x potency interaction for either potency or frequency of use. The within-group analysis showed in fact that the effects of potency and frequency were similar in FEP users and in users without psychosis.

CONCLUSIONS

Frequent use of high-potency cannabis is associated with disturbed callosal microstructural organization in individuals with and without psychosis. Since high-potency preparations are now replacing traditional herbal drugs in many European countries, raising awareness about the risks of high-potency cannabis is crucial.

Comparison of psychotic bipolar disorder, schizoaffective disorder, and schizophrenia: an international, multisite study

OBJECTIVE

Nosological distinctions among schizoaffective disorder (SA), bipolar I disorder with psychotic features (BDp), and schizophrenia (SZ) remain unresolved.

METHOD

We compared 2269 subjects with psychotic features in DSM-IV-TR diagnoses (1435 BDp, 463 SZ, 371 SA) from 8 collaborating international sites, by 12 sociodemographic and clinical measures, all between diagnostic pairs.

RESULTS

In bivariate comparisons, SA was consistently intermediate between BDp and SZ for 11/12 features (except onset stressors), and SZ vs. BDp differed in all 12 factors. SA differed from both BDp and SZ in 9/12 factors: SA and BDp were similar in education and suicidal ideation or acts; SA and SZ were similar in education, onset stressors, and substance abuse. Meta-analytic comparisons of diagnostic pairs for 10 categorical factors indicated similar differences of SA from both SZ and BDp. Multivariate modeling indicated significantly independent differences between BDp and SZ (8 factors), SA vs. SZ (5), and BDp vs. SA (3). Measurement variance was similar for all diagnoses.

CONCLUSION

SA was consistently intermediate between BDp and SZ. The three diagnostic groups ranked: BDp > SA > SZ related to lesser morbidity or disability. The findings are not consistent with a dyadic Kraepelinian categorization, although the considerable overlap among the three DSM-IV diagnostic groups indicates uncertain boundaries if they represent distinct disorders.

Topical distribution of initial paresis of the limbs to predict clinically relevant spasticity after ischemic stroke: a retrospective cohort study

BACKGROUND

The degree of initial paresis relates to spasticity development in stroke patients. However, the importance of proximal and distal paresis in predicting spasticity after stroke is unclear.

AIM

To investigate the role of topical distribution of initial limb paresis to predict clinically relevant spasticity in adults with stroke.

DESIGN

Retrospective cohort study

METHODS

Seventy-two first-ever ischemic stroke patients were examined. At the acute phase of illness, demographics and the European Stroke Scale motor items (maintenance of outstretched arm position, arm raising, wrist extension, grip strength, maintenance of outstretched leg position, leg flexion, foot dorsiflexion) were evaluated. At six months after the stroke onset, spasticity was assessed at the upper and lower limb with the modified Ashworth Scale. Clinically relevant spasticity was defined as modified Ashworth Scale ≥3 (0-5).

RESULTS

The degree of initial paresis of the proximal muscles of the upper limb and the distal muscles of the lower limb showed the strongest association and the best profile of sensitivity-specificity in predicting clinically relevant spasticity at the upper and lower limb, respectively. Younger age showed higher risk for developing clinically relevant spasticity in the upper limb.

CONCLUSIONS

Our findings support the hypothesis that the initial degree of proximal paresis of the upper limb and distal paresis of the lower limb as well as age may be considered early predictors of clinically relevant spasticity in adults with ischemic stroke.

CLINICAL REHABILITATION IMPACT

Our findings further improve the role of initial paresis as predictor of spasticity after stroke.

Validation of the Italian version of interpersonal sensitivity measure (IPSM) in adolescents and young adults

BACKGROUND

Interpersonal sensitivity is a personality trait that describes as excessive awareness of both the behaviour and feelings of others. High interpersonal sensitivity has been associated with the development and maintenance of mental health problems. This study aimed to examine whether the Italian version of the interpersonal sensitivity measure (IPSM) has good internal consistence and convergent validity.

METHODS

Validity was established on a sample of 153 Italian adolescents and young adult help seekers for several psychological problems. These subjects were divided in two groups - depressive spectrum disorder group (n=42) and other diagnosis group (n=111) - according to Structured Clinical Interview (SCID-I) for DSM-IV and Kiddie-Sads-Present and Lifetime Version (K-SADS-PL). For convergent validity, we studied the correlation between total and each subscale IPSM scores and the General Symptoms (included depressive and dysphoric symptoms) of Prodromal Questionnaire.

RESULTS

The internal consistency were adequate and comparable to the original Boyce and Parker study. The validity was good, as indicated by both the convergent validity analysis and the depressive spectrum disorder group and other diagnosis group comparison.

LIMITATIONS

The absence of another scale measuring interpersonal sensitivity to assess the construct validity of IPSM; the clinical heterogeneity of the sample; the absence of test re-test reliability of the instrument.

CONCLUSIONS

Analysis of the results of internal consistency and convergent validity of the IPSM indicates that this version translated into Italian is valid and reliable.

Behavioural, psychological, and temperamental predictors of risk suicide trend after brief psychodynamic psychotherapy

BACKGROUND

Evidence has shown that psychotherapy is effective for depression, whereas the outcome for suicide risk is unclear.

AIM

It was to investigate whether possible pre-treatment predictors of suicide risk (SR) decrease after a brief psychodynamic psychotherapy treatment and at follow-up.

PATIENTS AND METHODS

Forty-one patients were assessed at: baseline (T0) for clinical history, clinical family history, physical diseases, type of suffered abuse; after the treatment (T1); and, at six-month follow-up (T2) for mood ratings, temperamental features, and SR levels.

RESULTS

The levels of depression and cyclothymia decreased at T1 and T2 compared to T0; however, the distribution of the patients with high SR level was similar between T0 and T1, and at T2 it increased. T1-T0 SR (Δ1SR) was correlated with suicidality in the last month and with depression levels at T0; T2-T0 SR (Δ2SR) was correlated with many historical, clinical, and temperamental variables; T2-T1 SR (Δ3SR) was correlated with the presence of previous psychotherapy, abuse, and anxiety. Linear regression models revealed that Δ1SR was predicted by the suicidality in the last month; Δ2SR was not significantly predicted by any variable; and, Δ3SR was predicted by anxiety.

CONCLUSIONS

The treatment was able to decrease the depression but not the SR. Findings confirm the difficulty of affecting SR and the importance of carefully considering the anxiety and the previous experiences of abuse in order to manage the interruption of the psychotherapy.

Insomnia as a predictor of high-lethality suicide attempts

INTRODUCTION

Research has demonstrated that patients with insomnia are at an increased risk of experiencing suicidal ideation and/or making a suicide attempt.

OBJECTIVES

To evaluate the relation between insomnia and suicidal behaviour.

AIMS

To examine factors associated with a diagnosis of insomnia in patients admitted to an Emergency Department (ED) and assessed by the psychiatrist in charge.

METHODS

Participants were 843 patients consecutively admitted to the ED of Sant'Andrea Hospital in Rome, between January 2010 and December 2011. All patients admitted were referred to a psychiatrist. A clinical interview based on the Mini International Neuropsychiatric Interview (MINI) and a semi-structured interview was conducted. Patients were asked about 'ongoing' suicidal ideation or plans for suicide.

RESULTS

Forty-eight percent of patients received a diagnosis of bipolar disorder (BD), major depressive disorder (MDD) or an anxiety disorder; whereas, 17.1% were diagnosed with Schizophrenia or other non-affective psychosis. Patients with insomnia (compared to patients without insomnia) more frequently had a diagnosis of BD (23.9% vs. 12.4%) or MDD (13.3% vs. 9.5%; p < 0.001). Moreover, patients with insomnia less frequently had attempted suicide in the past 24 h (5.3% vs. 9.5%; p < 0.05) as compared with other patients, but those patients with insomnia who attempted suicide more frequently used a violent method (64.3% vs. 23.6%; p < 0.01) compared to other suicide attempters.

CONCLUSIONS

Our results do not support an association between insomnia and suicidal behaviour. However, suicide attempters with insomnia more frequently used violent methods, and this phenomenon should be taken into serious consideration by clinicians.

Anatomical substrates of cognitive and clinical dimensions in first episode schizophrenia

OBJECTIVE

To explore gray (GM) and white matter (WM) abnormalities and the relationships with neuropsychopathology in first-episode schizophrenia (FES).

METHOD

Nineteen patients with first episode of non-affective psychosis and 18 controls underwent a magnetic resonance voxel-based morphometry. Additionally, WM fractional anisotropy (FA) was calculated. For correlative analysis, symptoms and neuropsychological performances were scored by PANSS and by a comprehensive neuropsychological assessment respectively.

RESULTS

Patients showed significantly decreased volume of left temporal lobe and disarray of all major WM tracts. Disorganized PANSS factor was inversely related to left cerebellar GM volume (corrected P = 0.03) and to WM FA of the left cerebellum, inferior fronto-occipital fasciculi (IFOF), and inferior longitudinal fasciculi (corrected P < 0.05). PANSS negative factor was inversely related to FA in the IFOF and superior longitudinal fasciculi (corrected P < 0.05). Impairment in facial emotion identification showed associations with temporo-occipital GM volume decrease (corrected P = 0.003) and WM disarray of superior and middle temporal gyri, anterior thalamic radiation, and superior longitudinal fasciculi (corrected P < 0.05). Speed of processing and visual memory correlated with WM abnormalities in fronto-temporal tracts.

CONCLUSION

These results confirm how the structural development of key brain regions is related to neuropsychopathological dysfunction in FES, consistently with a neurodevelopmentally derived misconnection syndrome.

The structure of the corpus callosum in obsessive compulsive disorder

Abnormal brain connectivity has recently been reported in obsessive compulsive disorder (OCD). However, structural differences in the corpus callosum (CC), the primary structure connecting the two hemispheres, have not been extensively studied. In this case-control study, we recruited 30 patients with OCD and 30 healthy control subjects carefully matched for age, sex and handedness. Combining surface-based mesh-modeling and voxel-based morphometry (VBM), we compared callosal thickness and white matter (WM) density in patients and controls. We investigated associations between callosal structure and cortical gray matter (GM) density, and we related CC measures to neuropsychological performance in OCD. OCD patients showed small anterior and posterior callosal regions compared to healthy control subjects. In the OCD group, anterior callosal thickness was positively correlated with GM density of the right mid-dorso-lateral prefrontal (BA 9/46) area, while posterior callosal thickness was positively correlated with GM density in the left supramarginal gyrus (BA 40). Moreover, posterior callosal WM density was positively correlated with verbal memory, visuo-spatial memory, verbal fluency, and visuo-spatial reasoning performances. Callosal attributes were related to GM density in cortical areas innervated by the CC, and were also related to performance in cognitive domains impaired in the disorder. The CC may therefore be integrally involved in OCD.

Gene variants with suicidal risk in a sample of subjects with chronic migraine and affective temperamental dysregulation

BACKGROUND

Risk factors for suicide are at least partially heritable and functional polymorphisms of targeted genes have been suggested to be implicated in the pathogenesis of this phenomenon. However, other studies examining the association between specific gene variants and suicide revealed inconsistent findings. We aims to evaluate the possible association between MAO-A3, CYP1A2*1F and GNB3 gene variants, hopelessness and suicidal risk in a sample of subjects with chronic migraine and affective temperamental dysregulation.

METHODS

56 women were genotyped for MAO-A3, CYP1A2*1F and GNB3 gene variants. Participants were also assessed using Beck Hopelessness Scale (BHS), the Temperament Evaluation of the Memphis, Pisa, Paris and San Diego-Autoquestionnaire (TEMPS-A), and the Suicidal History Self-Rating Screening Scale (SHSS).

RESULTS

Patients with higher total scores on affective dysregulated temperaments are more likely to have higher BHS (11.27+/=5.54 vs. 5.73+/=3.81; t19.20 = -3.57; p < 0.01) and higher SHSS total scores (4.79+/=3.31 vs. 1.05±2.31; t17.74 = -3.90; p < 0.001) than those with lower total scores. 67% of patients in the dysregulated group has BHS total scores >= 9 indicating high levels of hopelessness. No association was found between MAO-A3, CYP1A2*1F and GNB3 gene variants and suicidal risk as assessed by BHS and SHSS.

CONCLUSIONS

This study did not sustain the association between MAO-A3, CYP1A2*1F and GNB3 gene variants and increased suicidal risk in patients with chronic migraine and affective temperamental dysregulation. Further studies investigating the gene-environment interaction or focusing on other genetic risk factors involved in suicidal behaviour are needed.  

Interpersonal sensitivity in the at-risk mental state for psychosis

BACKGROUND

Interpersonal sensitivity is a personality trait described as excessive awareness of both the behaviour and feelings of others. Although interpersonal sensitivity has been found to be one of the vulnerability factors to depression, there has been little interest in its relationship with the prodromal phase of psychosis. The aims of this study were to examine the level of interpersonal sensitivity in a sample of individuals with an at-risk mental state (ARMS) for psychosis and its relationship with other psychopathological features.

METHOD

Sixty-two individuals with an ARMS for psychosis and 39 control participants completed a series of self-report questionnaires, including the Interpersonal Sensitivity Measure (IPSM), the Prodromal Questionnaire (PQ), the Ways of Coping Questionnaire (WCQ) and the Depression and Anxiety Stress Scale (DASS).

RESULTS

Individuals with an ARMS reported higher interpersonal sensitivity compared to controls. Associations between interpersonal sensitivity, positive psychotic symptoms (i.e. paranoid ideation), avoidant coping and symptoms of depression, anxiety and stress were also found.

CONCLUSIONS

This study suggests that being 'hypersensitive' to interpersonal interactions is a psychological feature of the putatively prodromal phase of psychosis. The relationship between interpersonal sensitivity, attenuated positive psychotic symptoms, avoidant coping and negative emotional states may contribute to long-term deficits in social functioning. We illustrate the importance, when assessing a young client with a possible ARMS, of examining more subtle and subjective symptoms in addition to attenuated positive symptoms.
