Longitudinal trajectories of psychosocial functioning in patients with pre-existing mental disorders after one year of COVID-19 pandemic

Aims of the present study were to prospectively assess psychosocial functioning trajectories during the COVID pandemic and the possible impact of sociodemographic variables, as well as of COVID-19 pandemic-related factors, on these trajectories, in a sample of patients with pre-existing severe mental disorders. Moreover, we aimed at identifying predictors of impairment in psychosocial functioning over a period of 9 months of COVID-19 pandemic. Patients were recruited during the 3rd wave of the COVID-19 pandemic (T0, March-April 2021) while strict containment measures were applied in Italy, and reassessed after 3 months (T1, June-July 2021), and after 6 months from T1 (T2- November-December 2021), during the 4th wave of COVID pandemic. A sample of 300 subject (out of the 527 subjects recruited at baseline) completed the T2 evaluation. Patients were assessed by: Work and Social Adjustment Scale (WSAS) for psychosocial functioning, Generalized Anxiety Disorder 7-Item (GAD-7) for anxiety symptoms, Patient Health Questionnaire-9 (PHQ-9) for depressive symptoms and the Impact of Events Scale-Revised, for post-traumatic symptoms. Cluster analyses identified 4 trajectories of functioning: the High, Stable Functioning group (N = 77), the Improvement Functioning group (N = 62), the Progressive Impairment group (N = 83) and the Persistent Severe Impairment group (N = 78) respectively. We found that predictors of higher WSAS score at T2 were higher WSAS score at T0 (B = 0.43, p < .001), PHQ scores at baseline >10 (B = 2.89, p < .05), while not living alone was found to be a protective factor (B = -2.5, p < .05). Results of the present study provides insights into the vulnerability of individuals with psychiatric disorders during times of crisis. Study findings can contribute to a better understanding of the specific needs of this population and inform interventions and support strategies.

One-year efficacy of a lifestyle behavioural intervention on physical and mental health in people with severe mental disorders: results from a randomized controlled trial

This multicentric randomized controlled trial (RCT), carried out in six Italian University mental health sites, aims to test the efficacy of a six-month psychosocial intervention (LYFESTYLE) on Body Mass Index (BMI), body weight, waist circumference, fasting glucose, triglycerides, cholesterol, Framingham and HOmeostasis Model Assessment of insulin resistance (HOMA-IR) indexes in patients with schizophrenia, bipolar disorder, and major depression. Moreover, the efficacy of the intervention has also been tested on several other physical and mental health domains. Patients were randomly allocated to receive the six-month experimental intervention (LIFESTYLE) or a behavioural control intervention. All enrolled patients were assessed at baseline and after one year. We recruited 401 patients (206 in the experimental and 195 in the control group) with a diagnosis of schizophrenia or other psychotic disorder (29.9%), bipolar disorder (43.3%), or major depression (26.9%). At one year, patients receiving the experimental intervention reported an improvement in body mass index, body weight, waist circumference, HOMA-IR index, anxiety and depressive symptoms and in quality of life. Our findings confirm the efficacy of the LIFESTYLE intervention in improving physical and mental health-related outcomes in patients with severe mental illnesses after one year.

Validation of a polygenic risk score for Frailty in the Lothian Birth Cohort and English Longitudinal Study of Ageing

Frailty is a complex trait. Twin studies and a high-powered Genome Wide Association Study (GWAS) conducted in the UK Biobank have demonstrated a strong genetic basis of frailty. The present study utilized summary statistics from this GWAS to create and test the predictive power of frailty polygenic risk scores (PRS) in two independent samples - the Lothian Birth Cohort 1936 (LBC1936) and the English Longitudinal Study of Ageing (ELSA) aged 67-84 years. Multiple regression models were built to test the predictive power of frailty PRS at five time points. Frailty PRS significantly predicted frailty at all-time points in LBC1936 and ELSA, explaining 2.1% (β = 0.15, 95%CI, 0.085-0.21) and 1.6% (β = 0.14, 95%CI, 0.10-0.17) of the variance, respectively, at age ~68/~70 years (p < 0.001). This work demonstrates that frailty PRS can predict frailty in two independent cohorts, particularly at early ages (~68/~70). PRS have the potential to be valuable instruments for identifying those at risk for frailty and could be important for controlling for genetic confounders in epidemiological studies.

Joint synthesis and registration network for deformable MR-CBCT image registration for neurosurgical guidance

Objective.The accuracy of navigation in minimally invasive neurosurgery is often challenged by deep brain deformations (up to 10 mm due to egress of cerebrospinal fluid during neuroendoscopic approach). We propose a deep learning-based deformable registration method to address such deformations between preoperative MR and intraoperative CBCT.Approach.The registration method uses a joint image synthesis and registration network (denoted JSR) to simultaneously synthesize MR and CBCT images to the CT domain and perform CT domain registration using a multi-resolution pyramid. JSR was first trained using a simulated dataset (simulated CBCT and simulated deformations) and then refined on real clinical images via transfer learning. The performance of the multi-resolution JSR was compared to a single-resolution architecture as well as a series of alternative registration methods (symmetric normalization (SyN), VoxelMorph, and image synthesis-based registration methods).Main results.JSR achieved median Dice coefficient (DSC) of 0.69 in deep brain structures and median target registration error (TRE) of 1.94 mm in the simulation dataset, with improvement from single-resolution architecture (median DSC = 0.68 and median TRE = 2.14 mm). Additionally, JSR achieved superior registration compared to alternative methods-e.g. SyN (median DSC = 0.54, median TRE = 2.77 mm), VoxelMorph (median DSC = 0.52, median TRE = 2.66 mm) and provided registration runtime of less than 3 s. Similarly in the clinical dataset, JSR achieved median DSC = 0.72 and median TRE = 2.05 mm.Significance.The multi-resolution JSR network resolved deep brain deformations between MR and CBCT images with performance superior to other state-of-the-art methods. The accuracy and runtime support translation of the method to further clinical studies in high-precision neurosurgery.

Young and lonely? Results from the COMET study

Introduction

The sudden changes in daily routine due to the containment measures adopted for facing the COVID-19 pandemic have had an impact on the mental health of the general population. In particular, young adults are exposed to a higher risk compared to the general population to suffer from the consequences of the pandemic, in terms of anger and irritability, depressive symptoms and somatic complaints, insomnia, lack of motivation and loneliness. In particular, loneliness can be particularly pronounced during young adulthood.

Objectives

This study aimed to describe the levels of loneliness in a sample of Italian young people during the national lockdown in 2020, evaluating clinical and socio-demographic differences and the role of coping strategies and levels of resilience.

Methods

A sub-analysis of a sample of adults aged 18-34 years has been drawn on a larger cross-sectional observational national trial (COMET, 2020) in which, among other psychopathological dimensions, the levels of loneliness have been assessed by the UCLA scale short version.

Results

Levels of loneliness were particularly severe in a third of cases (risk factors: unemployment, low income and vulnerability in mental health), in association with depression, anxiety, stress, OCD symptoms, higher rates of suicidal ideation, sleep disturbance and excessive use of Internet. Levels of loneliness tended to increase over time.

Conclusions

Overall, during the Italian COVID-19 lockdown young people have experienced quite high levels of loneliness: this dimension could represent a useful domain to assess in routine clinical practice.

Preexisting mild cognitive impairment as a risk factor for COVID-19 infection: A scoping review and case reports

Introduction

SARS-Co-V2 neuroinvasive ability might be the basis for the onset of delirium and neuropsychiatric outcomes.

Objectives

We hypothesized that some infected patients with preexisting cognitive dysfunction may present delirium as unique manifestation of COVID-19 infection or as a prodrome of a new episode consistent with the psychiatric history.

Methods

We conducted a PubMed literature search to verify whether cognitive impairment might predispose to COVID-19. We included three patients with mild cognitive impairment and delirium at admission for SARS-Co-V2 suspected infection. Delirium was diagnosed according to DSM-5 criteria‚ Cognitive Assessment Method and Coma Glasgow Scale.

Results

Literature analysis evidenced patients presenting delirium or delirium-like symptoms as clinical manifestation of COVID-19, plus a cognitive impairment‚ from mild to severe‚ which preexisted or was evidenced during the acute phase or after the infection. Most studies described delirium in patients with a past neurological/psychiatric history. Contrasting data emerged on the potential link between COVID-19 and delirium in patients with cognitive impairment and without a past neuropsychiatric history. Our patients had no history of other medical complications. Our first patient had no psychiatric history‚ the second reported only a depressive episode‚ and the third had story of bipolar disorder. Delirium resolved completely after 2 days in the first patient. The other patients required 4 and 14 days to resolve: delirium appeared as the prodrome of a new psychiatric episode in line with their past history.

Conclusions

Clinicians should acknowledge the possibility that COVID-19 infection may appear as delirium and acute psychiatric sequelae as unique manifestation.

How can resilience moderate the effects of the COVID-19 pandemic on mental health?

Introduction

The COVID-19 pandemic represents a new form of trauma, which is impacting on the mental health of the general population. However, the effects of this new trauma are variable, being mediated by individual factors such as the levels of resilience and the coping strategies.

Objectives

The aims of the present study are: 1) describe the levels of resilience and the type of coping strategies adopted by the Italian general adult population during the first wave of the pandemic; 2) evaluate the protective role of coping strategies and resilience on the levels of depressive, anxiety and stress symptoms.

Methods

An online survey has been developed, which includes several validated self-reported questionnaires for the evaluation of participants’ mental health condition, coping strategies and levels of resilience. The main outcome measure is the Depression Anxiety and Stress Scale-21 (DASS-21).

Results

The finale sample consists of 20,720 participants, more than half reported low levels of resilience, which were not associated with age or gender. The levels of resilience did not differ among the general population, patients with pre-existing mental disorders and those infected by COVID-19. People with low levels of resilience rarely used adaptive coping strategies. The levels of resilience did not have any influence on stress, depressive or anxiety symptoms.

Conclusions

The presence of low levels of resilience in the general population may be the missing link between the pandemic and increasing concerns on mental health problems. This could be important for the development of ad-hoc supportive and preventive psychosocial interventions.

Psychoeducational family intervention for bipolar I disorder: medium and long-term efficacy

Introduction

Bipolar disorder (BD) is associated to high personal and social burden, impaired social functioning and high levels of disability. Recent studies have showed that relapse rates are significantly reduced in those patients whose families receive psychoeducational interventions. Even though most of available evidences are related to the short-term efficacy of psychoeducational family interventions (PFI). No evidence is available on medium and long-term efficacy.

Objectives

This study aims to assess the efficacy after one and five years of PFI in BD in terms of: 1) improvement of patients’ symptoms and global functioning; 2) improvement of relatives’ objective and subjective burden and coping strategies.

Methods

A multicenter, controlled, outpatient trial has been conducted in BD patients and their key relatives, recruited in 11 Italian mental health centers. Patient’s clinical status, social and personal functioning, burden of illness, and relative’s burden and coping strategies were assessed with specific instruments at baseline, after 1 year and after 5 years.

Results

137 families were recruited, 70 allocated to the experimental intervention. After one year, an increasing positive effect on patients’ clinical status, global functioning and objective and subjective burden was found. Moreover, were observed a reduced number of relapses and of hospitalizations after five years, compared to the control group. A reduction in the levels of family burden and an improvement of their coping strategies were also observed.

Conclusions

Positive effects of the experimental intervention persist over the mid and long-term period. PFI should be provided in mental health centres to patients with BD and their relatives.

Affective Temperaments and Suicidality in Patients with Bipolar Disorder

Suicide is one of the leading causes of death in patients with Bipolar Disorder (BD). Several risk factors linked to suicide attempts in patients with BD have been identified, including a long duration of illness, untreated BD, female sex, positive history for suicide attempts, comorbidity with substance abuse or personality disorders, anxiety, depressive polarity and recent psychiatric inpatient care. Recently affective temperaments have been considered as possible factors for suicide in BD. While hyperthymic temperament is associated with a reduced risk of suicide attempts, cyclothymic, irritable, depressive and anxious temperaments are more represented in patients with a positive history of suicide attempts. Moreover, cyclothymic and irritable temperaments are highly connected with both aggression and impulsivity, which play a role in suicidal behaviours. Despite this evidence, the predictive role of affective temperaments on suicide behaviours is still poorly studied. In this contribution, we will report results of a study aiming at assessing the relationship between affective temperaments and personal history of violent suicide attempts, in 74 patients with BD. Violent suicide attempts were positively associated with cyclothymic temperament and inversely to hyperthymic one. BD-I patients and patients with a clinical history of rapid cycling were significantly more represented in the group of patients with a history of violent suicide attempts. Our results suggest the role of affective temperaments in the suicidality of patients with BD.

Is Maternity Blues a risk factor for the onset of post-partum depression? A longitudinal Study

Introduction

The period after delivery is characterised by physical, hormonal and psychological changes. Up to 20% of women can present depressive and anxiety symptoms and difficulties in the interaction with the newborn, emotional lability. This condition is also called “Maternity Blues (MB)”.

Objectives

To: 1) assess the frequency of MB presentation of depressive symptoms immediately after the delivery; 2) identify those characteristics more frequently associated to the onset of depressive symptoms after the delivery; and 3) verify the hypothesis that the presence of maternity blues is a risk factor for the onset of a depressive episode in the 12 months after the delivery.

Methods

From December 2019 to February 2021 all women who gave birth at the University of Campania “Vanvitelli” were enrolled. Upon acceptance, they filled in the EPDS Scale. Sociodemographic, gynaecological, peripartum and psychiatric anamnesis was collected at baseline. Women have been reassessed after 1, 3, 6 and 12 months.

Results

359 women were recruited, with a mean EPDS score of 5.51. Among these, 83 reported the presence of MB (EPDS score≥10; 23.12%). Anxiety disorders with onset prior to pregnancy (p<.000), preeclampsia (p<.01), increased foetal health rate (p<.01), conflicts with relatives (p<.001) and anxiety disorders the partner (p<.01) emerged as predictors of Mb. The presence of MB increase 7 time the risk to have higher EPDS score at follow-up assessments (p<.000).

Conclusions

The presence of MB should always be assessed in the immediate post-partum and psychosocial interventions should be provided to women with MB to reduce its potential negative effect on mental health.

Does Vitamin D matter? The role of calcium homeostasis imbalance in clinical severity of psychiatric patients

Introduction

Vitamin D modulates the biosynthesis of neurotransmitters and neurotrophic factors and it is involved in the modulation of inflammatory responses, with a potential impact on clinical status of patients with severe mental disorders. Moreover, available evidences report that decreased blood levels of Vitamin D are associated to a worse course of psychotic and affective disorders.

Objectives

We assessed calcium homeostasis imbalance in a sample of inpatients and outpatients, referring to the Department of Psychiatry of University of Campania “Luigi Vanvitelli” in order to explore levels of Calcium, PTH and Vitamin D and their influence in clinical severity among this different subgroups.

Methods

All patients were administered The Brief Psychiatric Rating Scale (BPRS) to assess different domains of psychopathology. Vitamin D, Calcium and PTH levels were assessed in all patients. An-ad hoc schedule was administered for socio-demographic and clinical characteristics.

Results

The total sample consisted of 152 patients (75 males and 77 females with 47.3 ± 14.4 age at admission, 74 inpatients and 78 outpatients). Patients with lower level of Vitamin D are more likely to present higher number of relapses (p<0.05) and to be inpatients (<0.01). Finally, serum levels of Vitamin D were negatively correlated with all the BPRS subscales (p < 0.01).

Conclusions

Lower levels of Vitamin D correlate with a worse clinical outcome of patients with different psychiatric diagnosis. Our results highlight the importance to routinely assess PTH, Vit D and calcium levels, especially in inpatients. Moreover, Vitamin D may represent a valid add-on treatment for these patients.

Mediterranean-Type Diet and Brain Structural Change from 73 to 79 Years in the Lothian Birth Cohort 1936

OBJECTIVES

To test whether Mediterranean-type Diet (MeDi) at age 70 years is associated with longitudinal trajectories of total brain MRI volume over a six-year period from age 73 to 79.

DESIGN

Cohort study which uses a correlational design.

SETTING

Participants residing in the Lothian region of Scotland and living independently in the community.

PARTICIPANTS

A relatively healthy Scottish sample drawn from the Lothian Birth Cohort 1936.

MEASUREMENTS

Total brain volume measurements were available at ages 73, 76 and 79 (N ranged 332 to 563). Adherence to the MeDi was based on food frequency questionnaire data collected three years before the baseline imaging scans, and was used in growth curve models to predict the trajectory of total brain volume change.

RESULTS

No association was found (p>.05) between adherence to the MeDi at age 70 and total brain volume change from 73 to 79 years in minimally-adjusted (sex) or fully adjusted models controlling for additional health confounders.

CONCLUSIONS

Variation in adherence to the MeDi was not predictive of total brain atrophy over a six-year period. This suggests that previous findings of dietary associations with brain volume are not long lasting or become less important as ageing-related conditions account for greater variation in brain volume change. More frequent collection of dietary intake data is needed to clarify these findings.

Deformable MR-CT image registration using an unsupervised, dual-channel network for neurosurgical guidance

PURPOSE

The accuracy of minimally invasive, intracranial neurosurgery can be challenged by deformation of brain tissue - e.g., up to 10 mm due to egress of cerebrospinal fluid during neuroendoscopic approach. We report an unsupervised, deep learning-based registration framework to resolve such deformations between preoperative MR and intraoperative CT with fast runtime for neurosurgical guidance.

METHOD

The framework incorporates subnetworks for MR and CT image synthesis with a dual-channel registration subnetwork (with synthesis uncertainty providing spatially varying weights on the dual-channel loss) to estimate a diffeomorphic deformation field from both the MR and CT channels. An end-to-end training is proposed that jointly optimizes both the synthesis and registration subnetworks. The proposed framework was investigated using three datasets: (1) paired MR/CT with simulated deformations; (2) paired MR/CT with real deformations; and (3) a neurosurgery dataset with real deformation. Two state-of-the-art methods (Symmetric Normalization and VoxelMorph) were implemented as a basis of comparison, and variations in the proposed dual-channel network were investigated, including single-channel registration, fusion without uncertainty weighting, and conventional sequential training of the synthesis and registration subnetworks.

RESULTS

The proposed method achieved: (1) Dice coefficient = 0.82±0.07 and TRE = 1.2 ± 0.6 mm on paired MR/CT with simulated deformations; (2) Dice coefficient = 0.83 ± 0.07 and TRE = 1.4 ± 0.7 mm on paired MR/CT with real deformations; and (3) Dice = 0.79 ± 0.13 and TRE = 1.6 ± 1.0 mm on the neurosurgery dataset with real deformations. The dual-channel registration with uncertainty weighting demonstrated superior performance (e.g., TRE = 1.2 ± 0.6 mm) compared to single-channel registration (TRE = 1.6 ± 1.0 mm, p < 0.05 for CT channel and TRE = 1.3 ± 0.7 mm for MR channel) and dual-channel registration without uncertainty weighting (TRE = 1.4 ± 0.8 mm, p < 0.05). End-to-end training of the synthesis and registration subnetworks also improved performance compared to the conventional sequential training strategy (TRE = 1.3 ± 0.6 mm). Registration runtime with the proposed network was ∼3 s.

CONCLUSION

The deformable registration framework based on dual-channel MR/CT registration with spatially varying weights and end-to-end training achieved geometric accuracy and runtime that was superior to state-of-the-art baseline methods and various ablations of the proposed network. The accuracy and runtime of the method may be compatible with the requirements of high-precision neurosurgery.

Targetable Conformationally Restricted Cyanines Enable Photon-Count-Limited Applications*

Cyanine dyes are exceptionally useful probes for a range of fluorescence-based applications, but their photon output can be limited by trans-to-cis photoisomerization. We recently demonstrated that appending a ring system to the pentamethine cyanine ring system improves the quantum yield and extends the fluorescence lifetime. Here, we report an optimized synthesis of persulfonated variants that enable efficient labeling of nucleic acids and proteins. We demonstrate that a bifunctional sulfonated tertiary amide significantly improves the optical properties of the resulting bioconjugates. These new conformationally restricted cyanines are compared to the parent cyanine derivatives in a range of contexts. These include their use in the plasmonic hotspot of a DNA-nanoantenna, in single-molecule Förster-resonance energy transfer (FRET) applications, far-red fluorescence-lifetime imaging microscopy (FLIM), and single-molecule localization microscopy (SMLM). These efforts define contexts in which eliminating cyanine isomerization provides meaningful benefits to imaging performance.

Identification of risk-factors for the development of depressive symptoms in perinatal period: A longitudinal study

Introduction

Perinatal depression is a severe and disabling condition, which affects negatively both mothers’ and children’s mental health and well-being. About 12.8% of pregnant women report depressive symptoms in the perinatal period.

Objectives

The aims of the present study are to: 1) identify factors (socio-demographic and clinical) associated with an increased risk of developing PD; 2) promote a screening program on PD.

Methods

All pregnant women were assessed at each trimester of pregnancy, three days after the childbirth and after 1, 3, 6 and 12 months, with the Edinburgh Postpartum Depression Scale (EPDS). Women scoring ≥10 on the EPDS were invited to receive a full psychiatric evaluation to confirm the diagnosis.

Results

420 women were recruited. 52.9%, 27.6% and 31.6% of participants presented an EPDS≥ 10 score at The I, II and III trimester of pregnancy, respectively. The percentage of patients with and EPS score ≥19 is 16.6%, 6.8%, 6.8%, 11.3% and 7.8% in 3 days following the childbirth and after 3, 6, 9 and 12 months, respectively. Higher EPDS scores are predicted by the presence of anxiety symptoms before pregnancy and of depressive and anxiety symptoms in previous pregnancies (p<0.05). Women with family conflicts and with anxiety symptoms in the partner are more likely to report higher EPDS scores (p<0.001).

Conclusions

Our results confirm that perinatal depression is a highly prevalent condition. An early identification of depressive symptoms during this period is crucial in order to reduce the long-term negative impact on the mothers, the newborn and other family members.

The role of affective temperaments in predicting symptom severity in bipolar disorder

Introduction

Bipolar disorder (BD) is one of the most burdensome psychiatric illnesses, being associated with a negative long-term outcome and high suicide rate. Although affective temperaments are considered possible mediators of outcome, their role on the course and outcome of BD remains poorly studied.

Objectives

The aims of the present study are to describe the clinical characteristics of patients with BD more frequently associated with the different affective temperaments and to verify which affective temperaments are associated with a more severe clinical picture in a sample of patients with BD.

Methods

All patients with BD referring to the outpatient units of two Italian university sites have been recruited. Patients’ psychiatric symptoms, affective temperaments, and quality of life were investigated through validated assessment instruments.

Results

199 patients were recruited. 54.8% of patients had a diagnosis of bipolar I disorder. 56.8% of the sample reported at least one episode of aggressive behaviours and 30.2% of suicidal attempt. Predominant cyclothymic and irritable temperaments predicted more frequent relapses, a poorer quality of life (p<;0.05), more aggressive behaviours and suicide attempts (p<;0.01). The predominant hyperthymic disposition was a protective factor for several outcome measures, including relapses and suicidality (p<;0.01), and was correlated with a less severity of psychiatric symptoms and later age at onset (p<;0.05).

Conclusions

Early identification of affective temperaments in BD patients can help clinicians to identify those who could show a worse prognosis. A screening of affective temperaments can be useful to develop early targeted integrated pharmacological and psychosocial interventions.

The role of Vit D and parathyroid hormone in clinical severity of patients with bipolar disorder

Introduction

Vitamin D modulates the biosynthesis of neurotransmitters and neurotrophic factors, thus influencing mood and its alterations. Decreased blood levels of Vitamin D are involved in many psychiatric disorders, in particular, affective disorders. As regards bipolar disorder (BD), an association between vitamin D deficiency and severity of illness has been found.

Objectives

In this observational study, we assessed calcium homeostasis imbalance in a sample of patients with BD; in particular, we explored whether serum levels of PTH, Vitamin D and calcium influence the clinical presentation of BD and its symptom severity.

Methods

All patients were administered with validated assessment instruments to assess psychopathology, affective temperaments and global functioning. Vitamin D and PTH levels were assessed in all patients. An-ad hoc schedule was administered for socio-demographic and clinical characteristics.

Results

The total sample consisted of 199 patients (females: 51%; mean age: 47.1 ± 13.2 years). Levels of serum PTH were directly correlated with the total number of hospitalizations (p< 0.01), and of depressive (p< 0.0001), manic (p< 0.001) and hypomanic episodes (p< 0.01). Serum levels of Vitamin D were positively associated with age at first psychiatric contact and were inversely correlated with the total number of depressive episodes (p< 0.05) and cyclothymic temperament (p< 0.05).

Conclusions

Increased levels of PTH and Vit D correlate with a worse clinical outcome of patients with BD. Our results highlight the importance to routinely assess PTH, Vit D and calcium levels in BD patients. Moreover, vitamin D may represent a valid add-on treatment for these patients.

Psychopathological and psychosocial factors influencing physical health of people with mental disorders

Introduction

Severe mental disorders (SMD) are associated with higher morbidity rates and poorer health outcomes compared to the general population. They are more likely to be overweight, to be affected by cardiovascular diseases, and to have higher risk factors for chronic diseases.

Objectives

To assess physical health in a sample of patients with SMD and to investigate which mental health-related factors and other psychosocial outcomes could be considered predictors of poor physical health.

Methods

Patients referring to the psychiatric outpatients unit of the University of Campania “L. Vanvitelli” were recruited, and were assessed through validated assessment instruments exploring psychopathological status, global functioning and stigma. Physical health was assessed with an ad-hoc anthropometric schedule. A blood sample has been collected to assess levels of cholesterol, blood glucose, triglycerides, and blood insulin.

Results

75 patients have been recruited, with a mean age of 45.63±11.84 years. 30% of the sample had a diagnosis of psychosis, 27% of depression and 43% of bipolar disorder. A higher BMI is predicted by higher number of hospitalizations, a reduced score at MANSA (p<.000), and PSP (p<.05), and higher score at ISMI and BPRS (p<.05). A higher cardiovascular risk is predicted by a reduced MANSA score (p<.000), a higher ISMI score and a poorer adherence to pharmacological treatments (p<.05). Higher ISMI score (p<.0001) and number of hospitalizations (p<.05) are predictors of insulin-resistance.

Conclusions

Our study shows that psychosocial domains negatively influence physical health outcome. It is necessary to disseminate an integrated psychosocial intervention in order to improve patients’ physical health.

The reciprocal relation between stigma and suicidality in a sample of patients with affective disorders

Introduction

Suicide is one of the major public health concerns worldwide, currently listed as the 15th most common cause of death. Mental illness stigma may contribute to suicidality and is associated with social isolation and low self-esteem among people with affective disorders.

Objectives

The aim of the present study is to assess, in a sample of people with affective disorders, whether high levels of internalized stigma are associated to suicidal thoughts and behaviours.

Methods

60 outpatients diagnosed with depression or bipolar disorder according to DSM-5 have been recruited. Suicidal behaviours and ideation were assessed through the Columbia Suicide Severity Rating Scale (C-SSRS); internalized stigma through the Internalized Stigma of Mental Illness (ISMI) scale. Socio-demographic characteristics have been collected through an ad hoc schedule.

Results

62.9% of the sample was female, with a mean age of 45.7 (±14) years. About half of the sample had a diagnosis of major depression (54.8%). Patients with suicidal ideation reported higher score at ISMI “alienation” subscale (p<0,05), compared to those without suicidal ideation. Patients with a previous history suicide attempts reported higher score at “alienation” and “social withdrawal” ISMI subscales (p<0,05). Moreover, “alienation” ISMI subscale significantly correlated with suicidal ideation and behaviours (p<0,01).

Conclusions

These results are in line with the available literature, highlighting that stigma and suicidality are strongly correlated. This underline the importance of interventions at addressing internalizing stigma, in particular to those with previous suicidal attempts and with an active suicidal ideation.

Data-Driven Deformable 3D-2D Registration for Guiding Neuroelectrode Placement in Deep Brain Stimulation

PURPOSE

Deep brain stimulation is a neurosurgical procedure used in treatment of a growing spectrum of movement disorders. Inaccuracies in electrode placement, however, can result in poor symptom control or adverse effects and confound variability in clinical outcomes. A deformable 3D-2D registration method is presented for high-precision 3D guidance of neuroelectrodes.

METHODS

The approach employs a model-based, deformable algorithm for 3D-2D image registration. Variations in lead design are captured in a parametric 3D model based on a B-spline curve. The registration is solved through iterative optimization of 16 degrees-of-freedom that maximize image similarity between the 2 acquired radiographs and simulated forward projections of the neuroelectrode model. The approach was evaluated in phantom models with respect to pertinent imaging parameters, including view selection and imaging dose.

RESULTS

The results demonstrate an accuracy of (0.2 ± 0.2) mm in 3D localization of individual electrodes. The solution was observed to be robust to changes in pertinent imaging parameters, which demonstrate accurate localization with ≥20° view separation and at 1/10^th the dose of a standard fluoroscopy frame.

CONCLUSIONS

The presented approach provides the means for guiding neuroelectrode placement from 2 low-dose radiographic images in a manner that accommodates potential deformations at the target anatomical site. Future work will focus on improving runtime though learning-based initialization, application in reducing reconstruction metal artifacts for 3D verification of placement, and extensive evaluation in clinical data from an IRB study underway.

Psychosocial factors and hospitalisations for COVID-19: Prospective cohort study based on a community sample

BACKGROUND

While certain infectious diseases have been linked to socioeconomic disadvantage, mental health problems, and lower cognitive function, relationships with COVID-19 are either uncertain or untested. Our objective was to examine the association of a range of psychosocial factors with hospitalisation for COVID-19.

METHODS

UK Biobank, a prospective cohort study, comprises around half a million people who were aged 40-69 years at study induction between 2006 and 2010 when information on psychosocial factors and covariates were captured. Hospitalisations for COVID-19 were ascertained between 16th March and 26th April 2020.

RESULTS

There were 908 hospitalisations for COVID-19 in an analytical sample of 431,051 England-based study members. In age- and sex-adjusted analyses, an elevated risk of COVID-19 was related to disadvantaged levels of education (odds ratio; 95% confidence interval: 2.05; 1.70, 2.47), income (2.00; 1.63, 2,47), area deprivation (2.20; 1.86, 2.59), occupation (1.39; 1.14, 1.69), psychological distress (1.58; 1.32, 1.89), mental health (1.50; 1.25, 1.79), neuroticism (1.19; 1.00, 1.42), and performance on two tests of cognitive function - verbal and numerical reasoning (2.66; 2.06, 3.34) and reaction speed (1.27; 1.08, 1.51). These associations were graded (p-value for trend ≤ 0.038) such that effects were apparent across the full psychosocial continua. After mutual adjustment for these characteristics plus ethnicity, comorbidity, and lifestyle factors, only the relationship between lower cognitive function as measured using the reasoning test and risk of the infection remained (1.98; 1.38, 2.85).

CONCLUSIONS

A range of psychosocial factors revealed associations with hospitalisation for COVID-19 of which the relation with cognitive function, a marker of health literacy, was most robust.

Ureter Identification In an Inflammatory Pig Model Using a Novel Near-Infrared Fluorescent Dye

BACKGROUND AND OBJECTIVES

Ureters are at risk of injury in settings of inflammation and distorted anatomy. The use of a fluorescent dye can improve intraoperative ureteral identification without the need for any additional invasive procedures. Our team has previously described the development of a preclinical ureter-specific dye, UL-766, tested in a rat model. Here, we present the use of the fluorescent dye during laparoscopy to assist in ureteral identification in a swine model with an inflamed abdomen; the results of this study serve as proof of feasibility for use in the setting of tissue edema and erythema.

STUDY DESIGN/MATERIALS AND METHODS

With institutional approval, two 20-25 kg pigs underwent abdominal surgery with the use of a Food and Drug Administration-approved fluorescence laparoscopic system. Using standard laparoscopy, inflammation was induced with sharp and blunt dissection and irritation was induced with gauze. The animals were allowed to recover and returned to the operating room after 7 days. Images of the inflamed right retroperitoneum, with fluorescence imaging, turned on, were taken before and after intravenous injection of the novel fluorescent dye at 120 μg/kg. The time until fluorescence visualization of the ureters was measured, and the fluorescent signal was measured for up to 4 hours from the time of the initial dye injection. Partial and complete transection of ureteral injuries was made by scissors and monitored under both standard video and fluorescence laparoscopy.

RESULTS

Inflammation reduced the certainty of ureter identification by white light alone. Despite surrounding tissue erythema and edema, ureteral visualization under fluorescence laparoscopy was achieved within 5-10 minutes after dye injection. The fluorescent signal remained visible for at least 4 hours after injection, and the fluorescent dye showed a partial ureteral injury that would not have been observed under standard laparoscopy.

CONCLUSIONS

UL-766 is a preclinical fluorescent dye useful for the intraoperative identification of the ureters and ureteral injuries in an inflamed abdomen. With the acquisition of additional preclinical data, this novel dye can be a valuable tool during laparoscopic abdominal and pelvic surgeries. Lasers Surg. Med. © 2019 Wiley Periodicals, Inc.

Coercive measures in italian inpatient units: results from eunomia study

Introduction

The use of coercive measures in clinical practice represents a common, but understudied problem in Europe. In 2002–2005, the European Commission funded the study “European Evaluation of coercion in psychiatry and harmonization of best clinical practice” (EUNOMIA), coordinated by the Department of Psychiatry of the University of Dresden and carried out in 12 European countries.

Objectives

This study, carried out on the Italian EUNOMIA sample, aims to:

1)

Methods

The Italian sample included 294 admitted patients. Data were collected on coercive measures (physical restraint, seclusion and forced medication)

Results

Almost 30% of the patients received coercive measures during their hospitalization; in particular, 22% received forced medication, 9% were restrained or fixed by mechanic devices, 7% were seclused. The most frequent reason for prescribing coercive measures was aggression against others. Patients who received coercive measures were more frequently male, with higher BPRS scores and a worse social functioning. At three months after discharge, they showed higher levels of positive symptoms, and reported more negative opinions on the need of hospital admission and on the appropriateness of psychiatric treatments.

Conclusions

In Italy coercive measures are in most of the cases applied to the patients affected by more severe psychopathology and disability.

The state of the art in European research on reducing social exclusion and stigma related to mental health: A systematic mapping of the literature

Stigma and social exclusion related to mental health are of substantial public health importance for Europe. As part of ROAMER (ROAdmap for MEntal health Research in Europe), we used systematic mapping techniques to describe the current state of research on stigma and social exclusion across Europe. Findings demonstrate growing interest in this field between 2007 and 2012. Most studies were descriptive (60%), focused on adults of working age (60%) and were performed in Northwest Europe—primarily in the UK (32%), Finland (8%), Sweden (8%) and Germany (7%). In terms of mental health characteristics, the largest proportion of studies investigated general mental health (20%), common mental disorders (16%), schizophrenia (16%) or depression (14%). There is a paucity of research looking at mechanisms to reduce stigma and promote social inclusion, or at factors that might promote resilience or protect against stigma/social exclusion across the life course. Evidence is also limited in relation to evaluations of interventions. Increasing incentives for cross-country research collaborations, especially with new EU Member States and collaboration across European professional organizations and disciplines, could improve understanding of the range of underpinning social and cultural factors which promote inclusion or contribute toward lower levels of stigma, especially during times of hardship.

Quinoline-annulated porphyrin platinum complexes as NIR emitters

The platinum(II) complexes of known quinoline-annulated porphyrins were prepared and spectroscopically characterized. Their optical properties (UV-vis absorption and phosphorescence spectra and phosphorescence lifetimes) were recorded and contrasted against their 2,3-dioxoporphyrin precursor platinum(II) complex. The absorbance and emission spectra (in EtOH glass at 77 K) of the quinoline-annulated porphyrins fall within the NIR optical window of tissue, ranging, depending on the derivative, between [Formula: see text]950 and 1200 nm. The much red-shifted optical spectra, when compared to their non-quinoline-annulated precursors, are attributed to the [Formula: see text]-extension and conformational non-planarity that the annulation causes. The emission yields of the mono-quinoline-annulated derivatives are too low and their lifetimes too short to be practical emitters, but the bis-annulated derivative possesses a practical lifetime and emission yield, suggesting its further exploration, particularly since the methodology toward the solubilization of the quinoline-annulated porphyrins in biological media through derivatization is known.

Identification of Priority Areas for Increased Testing Using Geospatial Mapping of Incident HIV Cases Near Charleston, South Carolina

Analysis of disease incidence using geospatial mapping techniques can enhance targeted public health efforts in resource-limited settings. While data for HIV incidence are readily available for some metropolitan regions, there is no existing resource that maps HIV incidence geospatially for Charleston, South Carolina and surrounding counties. To facilitate the public health approach to address the HIV epidemic in this region, we used data collected by the South Carolina Department of Health and Environmental Control (SC-DHEC) from 2014 to 2015 to generate local geospatial maps of disease incidence and identify specific areas that may benefit from increased testing and educational efforts. We identified specific zip codes in which there were a high number of cases from patients residing in those areas, but a low number of providers reporting new cases, and we describe ongoing efforts to address this disparity. This analysis identifies a local, collaborative approach to address the HIV epidemic using routinely collected surveillance data.

Does the Presence or Absence of DESH Predict Outcomes in Adult Hydrocephalus?

BACKGROUND AND PURPOSE

The DESH (disproportionately enlarged subarachnoid-space hydrocephalus) pattern of "tight high-convexity and medial subarachnoid spaces, and enlarged Sylvian fissures with ventriculomegaly" is used to determine which patients undergo an operation for adult hydrocephalus at many centers. Our aim was to review adult hydrocephalus cases when DESH has not been a criterion for an operation to determine the prevalence of DESH among the cohort and compare the surgical outcomes in the presence or absence of DESH.

MATERIALS AND METHODS

A retrospective cohort study was conducted at a single institution (Johns Hopkins Hospital) to include patients surgically treated for adult hydrocephalus between 2003 and 2014 drawn from a data base of patients who had undergone standardized hydrocephalus protocol MR imaging. Preoperative imaging was reviewed by 2 blinded neuroradiologists to characterize the presence of DESH. Preoperative and postoperative clinical symptomatology was recorded. Frequencies were compared using the Fisher exact test, and nonparametric means were compared using the Mann-Whitney U Test.

RESULTS

One hundred thirty-three subjects were identified and included (96 DESH absent, 37 DESH present). Shunting led to significant improvement in gait and urinary and cognitive symptoms for the overall cohort and for patients with and without DESH (P < .05). The Fisher exact test did not demonstrate any significant differences in either gait or urinary or cognitive symptom improvement between patients with or without DESH (P > .05).

CONCLUSIONS

The current study demonstrated symptom improvement in patients with adult hydrocephalus following shunting, with no significant differences between subjects with and without DESH. Thus, shunt insertion for patients with adult hydrocephalus should not rely solely on the presence of preoperative DESH findings.

Subthreshold autism spectrum disorder in patients with eating disorders

AIM

Increasingly data suggest a possible overlap between psychopathological manifestations of eating disorders (EDs) and autism spectrum disorders (ASD). The aim of the present study was to assess the presence of subthreshold autism spectrum symptoms, by means of a recently validated instrument, in a sample of participants with EDs, particularly comparing participants with or without binge eating behaviours.

METHODS

138 participants meeting DSM-5 criteria for EDs and 160 healthy control participants (HCs), were recruited at 3 Italian University Departments of Psychiatry and assessed by the SCID-5, the Adult Autism Subthreshold Spectrum (AdAS Spectrum) and the Eating Disorders Inventory, version 2 (EDI-2). ED participants included: 46 with restrictive anorexia (AN-R); 24 with binge-purging type of Anorexia Nervosa (AN-BP); 34 with Bulimia Nervosa (BN) and 34 with Binge Eating Disorder (BED). The sample was split in two groups: participants with binge eating behaviours (BEB), in which were included participants with AN-BP, BN and BED, and participants with restrictive behaviours (AN-R).

RESULTS

participants with EDs showed significantly higher AdAS Spectrum total scores than HCs. Moreover, EDs participants showed significantly higher scores on all AdAS Spectrum domains with the exception of Non verbal communication and Hyper-Hypo reactivity to sensory input for AN-BP participants, and Childhood/Adolescence domain for AN-BP and BED participants. Participants with AN-R scored significantly higher than participants with BEB on the AdAS Spectrum total score, and on the Inflexibility and adherence to routine and Restricted interest/rumination AdAS Spectrum domain scores. Significant correlations emerged between the Interpersonal distrust EDI-2 sub-scale and the Non verbal communication and the Restricted interest and rumination AdAS Spectrum domains; as well as between the Social insecurity EDI-2 sub-scale and the Inflexibility and adherence to routine and Restricted interest and rumination domains in participants with EDs.

CONCLUSIONS

Our data corroborate the presence of higher subthreshold autism spectrum symptoms among ED participants with respect to HCs, with particularly higher levels among restrictive participants. Relevant correlations between subthreshold autism spectrum symptoms and EDI-2 Subscale also emerged.

Modifications of Porphyrins and Hydroporphyrins for Their Solubilization in Aqueous Media

The increasing popularity of porphyrins and hydroporphyrins for use in a variety of biomedical (photodynamic therapy, fluorescence tagging and imaging, photoacoustic imaging) and technical (chemosensing, catalysis, light harvesting) applications is also associated with the growing number of methodologies that enable their solubilization in aqueous media. Natively, the vast majority of synthetic porphyrinic compounds are not water-soluble. Moreover, any water-solubility imposes several restrictions on the synthetic chemist on when to install solubilizing groups in the synthetic sequence, and how to isolate and purify these compounds. This review summarizes the chemical modifications to render synthetic porphyrins water-soluble, with a focus on the work disclosed since 2000. Where available, practical data such as solubility, indicators for the degree of aggregation, and special notes for the practitioner are listed. We hope that this review will guide synthetic chemists through the many strategies known to make porphyrins and hydroporphyrins water soluble.

Are coping strategies really different among family members of patients with eating disorders?

Introduction

Family members of patients with Eating Disorders(EDs)–in dealing with the relatives’ disease–report negative feelings such as self-blame and criticism, but little is known regarding their coping strategies.

Objectives

To describe coping strategies in a sample of relatives of patients with EDs using the Family Coping Questionnaire–Eating Disorder version (FCQ-ED).

Aims (1) To evaluate coping strategies in relatives of patients with EDs; (2) to describe differences in coping strategies according to type of kinship with the patient; (3) to identify correlations among socio-demographic characteristics, patients’ clinical characteristic, and type of coping strategies.

Methods

Relatives’ coping strategies were evaluated using the FCQ-ED, a self-administered questionnaire, consisting of 32 items, grouped in 5 subscales: coercion; positive communication; collusion; seeking for information; avoidance, plus one item on seeking for spiritual help.

Results

Seventy-two patients and 127 relatives were recruited. The most frequently adopted coping strategies were seeking for information, positive communication, seeking for spiritual help; the former were positively correlated with the level of education of both patients and relatives. Mothers avoided the patients less frequently than other relatives.

Discussion

This is one of the first studies focused on coping strategies in families of patients with EDs showing that problem-oriented ones are used quite often. Socio-demographic characteristics and type of kinship can have an impact on the adoption of coping strategies, but further longitudinal studies are needed in order to identify other possible factors implied in their development.

Conclusions

This represents an initial attempt to understand how clinical, social and personal variables can have an impact on the development of coping strategies.

Psychoeducational Family Intervention: Benefits and Obstacles Reported by Mental Health Professionals

Introduction

Despite several guidelines recommend the use of psychoeducational family interventions (PFIs) as add-on in the treatment of patients with bipolar I disorder (a), their implementation on a large scale remains limited (b).

Objectives

To identify benefits and obstacles in implementing a PFI in the clinical routine care.

Methods

This was a multicentre, real-world, controlled, outpatient trial, carried out in 11 randomly recruited Italian mental health centres. Mental health professionals received a training on PFI and provided the intervention to patients with bipolar I disorder and their relatives. Difficulties and benefits in performing PFI were collected through an ad-hoc schedule, which was administered at baseline and 5 times during the different stages of the intervention.

Results

Mental health professionals report significant improvements in the intervention-related benefits over time (T0 = 5.3 ± 2.0 vs. T5 = 7.9 ± 0.9; P < .0001), in particular in their professional skills (T0 = 6.5 ± 2.3 vs. T5 = 8.0 ± 0.8; P < .01). They also report to be more satisfied with their own work (T0 = 6.6 ± 2.3 vs. T5 = 8.0 ± 1.3; P < .05). The most relevant difficulties were related to the need to integrate the PFI with other work responsibilities and to the lack of time, which did not decrease overtime.

Conclusions

PFIs are feasible in routine care for the treatment of patients with bipolar I disorder and their relatives, and main obstacles are related to the organization of mental health centres, and not to the characteristics of the intervention itself.

Effectiveness of Psychoeducational Family Intervention on Coping Strategies of Relatives of Patients with Bipolar I Disorder

Background

Relatives’ coping strategies – an essential element for the recovery of patients with severe mental disorders – are grouped in problem-oriented and emotion-focused. The former include practical strategies to deal with the stressful situation and are associated with a better long-term outcome of patients and relatives; the latter are psychologically driven and are associated with a worse outcome. It has been reported that psychoeducational family intervention (PFI) can improve problem-oriented coping strategies, while few data are available on relatives of patients with bipolar disorder.

Objectives

To assess the impact of the PFI on promotion of problem-oriented coping strategies adopted by relatives of patients with bipolar I disorder.

Methods

This study was conducted in 11 Italian mental health centers. Patients and their relatives were allocated to the experimental group receiving PFI or to the control group (waiting list). Before starting the intervention and at the end of the PFI, coping strategies were assessed using the family coping questionnaire.

Results

Of the 139 recruited families, 72 families were allocated to the experimental group and 67 to the control group. Relatives from the experimental group reported a significant improvement in problem-oriented coping strategies, such as positive communication (P < .01) and searching for information (P < .05). On the other hand, a reduction in collusion (P < .0001), avoidance (P < .01) and resignation (P < .001) were found at the end of the intervention.

Conclusions

PFI is effective in promoting the coping strategies in relatives of patients with bipolar I disorder and it should be given routinely in mental health centers.

Autistic Traits in Patients with Anorexia Nervosa, Bulimia Nervosa or Binge Eating Disorder: A Pilot Study

Introduction

Previous data showed higher autistic traits in individuals with anorexia nervosa (AN) compared to healthy controls (CTL). It is not known, however, whether this characteristic is shared by other feeding and eating disorders (FEDs) or it is uniquely associated to AN.

Objectives

To compare autistic traits among individuals with AN, bulimia nervosa (BN), binge eating disorder (BED) and CTL and to investigate which specific dimensions differentiate one group from another.

Methods

A total of 241 FED patients (53 AN, 41 BN, 42 BED) and 105 CTL were administered the autism-spectrum quotient (AQ), the adult autism subthreshold spectrum (AdAS Spectrum), the Ritvo autism and Asperger diagnostic scale 14-item (RAADS-14 Screen).

Results

FED subjects reported higher AQ, AdAS spectrum and RAADS-14 total and subscales scores compared to CTL (all P < .001). No differences were found amongst AN, BN and BED subjects in questionnaires’ total scores. BN group scored higher than AN in the hyper-/hyporeactivity to sensory input domain of the AdAS spectrum (P < .001); AN group scored higher than BED in the attention switching domain of the AQ (P < .001), and BED group scored lower than both AN and BN in the mentalizing deficit domain of the RAADS-14 (all P < .001).

Conclusions

We reported for the first time that not only AN but also BN and BED patients show greater autistic traits compared to CTL. Longitudinal studies are needed to confirm this preliminary report and to elucidate whether autistic traits either precede, co-occur or follow FEDs.

Psychoeducational family intervention for people with eating disorders: Rationale and development

Introduction

Family members of patients with EDs report high levels of burden, psychological distress and the need to receive information on the disease of their ill relative. There is the need to provide family members and patients with psychoeducational family intervention in order to satisfy their care needs.

Objective

To develop a new psychoeducational approach for patients with Eating Disorders (EDs) and their relatives according to the Falloon model.

Aims

(1) To develop a family psychoeducational intervention for patients with EDs. (2) To implement the experimental intervention in the clinical routine care. (3) To evaluate efficacy of the approach in terms of reduction of family burden and improvement of relatives’ coping strategies.

Results

The Department of Psychiatry of the University of Naples SUN has developed a new psychoeducational family intervention for patients with EDs and their family members. The intervention consists of 6 sessions, scheduled weekly. The sessions deal with several topics such as information on EDs (e.g., causes, symptoms, clinical characteristics), communication skills (e.g., how to express an unpleasant feeling) and problem solving skills. The intervention is led by trained mental health professionals, such as psychiatrists, psychologists or rehabilitation technicians.

Discussion

This is the first example of psychoeducational intervention for families of patients with EDs developing according to the Falloon approach.

Conclusions

Family intervention represents an essential tool to provide to patients with EDs and their family members in order to promote a global recovery.

Adult Autism Subthreshold Spectrum (AdAS Spectrum): Validation of a questionnaire investigating subthreshold autism spectrum

AIM

Increasing literature has shown the usefulness of a dimensional approach to autism. The present study aimed to determine the psychometric properties of the Adult Autism Subthreshold Spectrum (AdAS Spectrum), a new questionnaire specifically tailored to assess subthreshold forms of autism spectrum disorder (ASD) in adulthood.

METHODS

102 adults endorsing at least one DSM-5 symptom criterion for ASD (ASDc), 143 adults diagnosed with a feeding and eating disorder (FED), and 160 subjects with no mental disorders (CTL), were recruited from 7 Italian University Departments of Psychiatry and administered the following: SCID-5, Autism-Spectrum Quotient (AQ), Ritvo Autism and Asperger Diagnostic Scale 14-item version (RAADS-14), and AdAS Spectrum.

RESULTS

The AdAS Spectrum demonstrated excellent internal consistency for the total score (Kuder-Richardson's coefficient=.964) as well as for five out of seven domains (all coefficients>.80) and sound test-retest reliability (ICC=.976). The total and domain AdAS Spectrum scores showed a moderate to strong (>.50) positive correlation with one another and with the AQ and RAADS-14 total scores. ASDc subjects reported significantly higher AdAS Spectrum total scores than both FED (p<.001) and CTL (p<.001), and significantly higher scores on the Childhood/adolescence, Verbal communication, Empathy, Inflexibility and adherence to routine, and Restricted interests and rumination domains (all p<.001) than FED, while on all domains compared to CTL. CTL displayed significantly lower total and domain scores than FED (all p<.001). A significant effect of gender emerged for the Hyper- and hyporeactivity to sensory input domain, with women showing higher scores than men (p=.003). A Diagnosis* Gender interaction was also found for the Verbal communication (p=.019) and Empathy (p=.023) domains. When splitting the ASDc in subjects with one symptom criterion (ASD₁) and those with a ASD, and the FED in subjects with no ASD symptom criteria (FED₀) and those with one ASD symptom criterion (FED₁)_, a gradient of severity in AdAS Spectrum scores from CTL subjects to ASD patients, across FED₀, ASD₁, FED₁ was shown.

CONCLUSIONS

The AdAS Spectrum showed excellent internal consistency and test-retest reliability and strong convergent validity with alternative dimensional measures of ASD. The questionnaire performed differently among the three diagnostic groups and enlightened some significant effects of gender in the expression of autistic traits.

In vivo photoacoustic tumor tomography using a quinoline-annulated porphyrin as NIR molecular contrast agent

The synthesis and photophysical properties of a tetra-PEG-modified and freely water-soluble quinoline-annulated porphyrin are described. We previously demonstrated the ability of quinoline-annulated porphyrins to act as an in vitro NIR photoacoustic imaging (PAI) contrast agent. The solubility of the quinoline-annulated porphyrin derivative in serum now allowed the assessment of the efficacy of the PEGylated derivative as an in vivo NIR contrast agent for the PAI of an implanted tumor in a mouse model. A multi-fold contrast enhancement when compared to the benchmark dye ICG could be shown, a finding that could be traced to its photophysical properties (short triplet lifetimes, low fluorescence and singlet oxygen sensitization quantum yields). A NIR excitation wavelength of 790 nm could be used, fully taking advantage of the optical window of tissue. Rapid renal clearance of the dye was observed. Its straight-forward synthesis, optical properties with the possibility for further optical fine-tuning, nontoxicity, favorable elimination rates, and contrast enhancement make this a promising PAI contrast agent. The ability to conjugate the PAI chromophore with a fluorescent tag using a facile and general conjugation strategy was also demonstrated.

Quinoline-annulated chlorins and chlorin-analogs

The OsO4-mediated dihydroxylation of quinoline-annulated porphyrin generates a quinoline-annulated dihydroxychlorin in a regioselective fashion. Its dihydroxypyrroline moiety, located at the opposite of the annulated pyrrole, is susceptible to the same functional group interconversions we previously demonstrated for non-annulated dihydroxychlorins: oxidations to the corresponding dione, lactone, and dialkoxymorpholine derivatives. The quinoline-annulated chlorin and derivatives are all characterized by absorption spectra that are much broadened and between 130 and 220 nm red-shifted compared to their non-annulated analogs. Absorbance maxima in the NIR up to well above 800 nm were recorded. We attribute the bathochromic shift to their extended [Formula: see text]-systems and inferred non-planarity, highlighting that quinoline-annulation is a particularly effective and simple strategy to red-shift the absorption spectra of chlorins and chlorin analogs.

Perceived insecurity, mental health and urbanization: Results from a multicentric study

AIMS

This article aims to (1) explore the levels of perceived insecurity in a sample of patients with mood or anxiety disorders and (2) assess whether living in 'big cities' can influence the levels of patients' perceived insecurity and social contacts compared to living in a non-urbanized context.

METHODS

A total of 24 Italian mental health centers (MHCs) have been invited to participate. Twenty patients consecutively accessing the MHC have been recruited. All patients have been assessed using validated assessment tools.

RESULTS

The sample consisted of 426 patients, mostly female, with a mean age of 45 years. Globally, 52.2% of patients had a diagnosis of mood disorders, and 37.8% had anxiety disorders. Half of the sample declared that the main feeling toward life is uncertainty; higher levels of pessimistic views toward life have been detected in patients living in urban areas. A positive association between negative attitudes toward life and higher levels of depressive and anxiety symptoms, poor social functioning and higher levels of perceived psychological distress has been found.

CONCLUSION

Our findings confirm the presence of a common sense of perceived uncertainty among our sample. Such attitude toward life can have a detrimental impact on patients' psychological and physical well-being, contributing to high levels of distress.

Does the use of coercion improve the outcome of patients with severe mental disorders?

Coercive measures have always been part of the psychiatric armamentarium; however, the clinical and ethical dilemma between the use of a “therapeutic” coercion and the loss of patients’ dignity is one of the most controversial issues in mental health practice. According to International guidelines, coercive measures should be adopted only when all the other less restrictive approaches failed and should be considered as the “last restrictive alternative”. Although coercive measures are frequently used to manage patients’ aggressive behaviors and self-harm, refusal of medication and impulsivity, their effect on patients’ outcome is not clear. In fact, the use of coercive measures can reduce patients’ aggressiveness and improve psychiatric symptoms, but can also have a negative impact in terms of therapeutic relationship, engagement with mental health services and self-stigma, arising negative feelings on patients and on mental health professionals. International attempts have been made to improve and harmonize the use of involuntary treatments. Recommendations of good clinical practice on the use of coercive involountary treatments and forced medications have been proposed by the EUNOMIA consortium, and the effect of coercion on the outcome of patients with severe mental disorders have been described. Results of this study will be reported as well as lessons learnt from other international experiences.

Supersizing pyrrole-modified porphyrins by reversal of the ‘breaking and mending’ strategy

A pyrrole inmeso-tetraphenylporphyrin was expanded by annulation ofN,N′-dimethylurea to a porphyrin β,β′-dione and subsequent merger of the pyrrole and urea atoms into an 8-membered ring.
