Subjects with eating disorders (ED) show a high prevalence of childhood trauma.
Objectives
Aim of the study is to evaluate the emotional, biological and behavioral responses to an experimental acute psychosocial stress in subjects with ED with or without childhood maltreatment. Secondary aim is to evaluate the effects of different traumatic experiences (physical and emotional).
Methods
48 women with ED completed the Childhood Trauma Questionnaire (CTQ). 29 participants (14 with Anorexia Nervosa [AN] and 15 with Bulimia Nervosa [BN]) reported an history of childhood maltreatment, while 19 (11 with AN and 8 with BN) did not. Cortisol levels, anxiety and hunger perceptions have been assessed in all participants throughout the Trier Social Stress Test (TSST) as well as body dissatisfaction after stress exposure.
Results
Subjects with childhood trauma showed higher emotional reactivity and body dissatisfaction and lower hunger throughout the TSST than those without childhood trauma. Higher cortisol levels were observed in patients with AN, regardless of the presence of childhood trauma, and in those with BN and history of emotional trauma. Emotional trauma was the childhood trauma explaining most of the observed differences.
Conclusions
Childhood trauma, especially emotional one, can lead to vulnerability to interpersonal stress in individuals with ED. The present study is the first that supports the “maltreated ecophenotype” hypothesis in subjects with ED through an experimental task and the evaluation of multiple levels of response. These data may provide new prospectives on the pathogenetic mechanisms of ED and novel therapeutic implications.
Disasters may have major impacts to mental health and to the utilization of mental health services (MHS). Moreover, these effects may be worsened by the preclusion of access to basic services following the event. The aim of this study is to evaluate the utilization of public MHS by the population that suffered water supply interruption following the Mariana Dam Failure in Brazil, 2015.
Methods:
We conducted an Interrupted Time Series analyzing secondary health data from the municipalities that faced water supply interruption, comparing it to data from the other municipalities of Minas Gerais state.
Results:
We found a higher immediate (RR: 1.78; 95% CI: 1.25–2.53) and gradual (RR: 1.05; 95% CI: 1.03–1.06) change in the rate of mental health visits (MHV) in the affected population following the event, whereas there was an immediate fall (RR: 0.41; 95% CI: 0.29–0.59) followed by a higher gradual increase (RR: 1.04; 95% CI: 1.02–1.06) in the rate of hospital admissions (HA) in the affected population.
Conclusion:
The results suggest that there was an increase in the utilization of public MHS by the population that suffered water supply interruption following the disaster.
Literature highlights that interpersonal sensitivity represents an important development and maintaining factor for Eating Disorder (ED). Mentalizing and empathy are two psychological constructs that play a crucial role in social functioning. However, the role of mentalizing and empathy in the socio-emotional processing deficits of ED patients has been under investigated.
Objectives
We aimed to assess the complex interactions between the sub-components of mentalizing and empathy and ED symptoms through a network analysis approach.
Methods
Seventy-seven women with EDs were included in our study. Eating disorder and affective symptomatology were investigated with self-report questionnaires. All patients underwent two computerized tasks: Movie for the Assessment of Social Cognition (MASC), assessing emotional and non-emotional mental state inferences; Empathic Accuracy Task-Revised (EAT-R), measuring accuracy in identifying and sharing others’ emotions. A partial correlation network and bridge function analyses were computed.
Results
In the partial correlation network inference of cognitive mental states and shape concern were the nodes with the highest strength centrality. Inference of emotional mental states was the node with the highest bridge strength in the cluster of social cognition functions. Empathic and mentalizing abilities were directly connected with each other and with ED symptoms.
Conclusions
This is the first network analysis study which integrates self-reported symptoms and objective socio-cognitive performance in people with Eds. Our results provide evidence of the complex interactions between mentalizing, empathy and psychopathological symptoms in people with EDs. Therefore, confirm that the ability to infer others’ mental state may represent a useful target for clinical intervention in EDs.
A large body of literature suggests that childhood trauma exposure is a non-specific risk factor for development of eating disorders (EDs) later in life. One potential mechanism through which early traumatic experiences may increase the risk for EDs is represented by long-lasting changes in the body stress response system.
Objectives
We investigated the activity of the hypothalamus-pituitary-adrenal axis and of the sympathetic nervous system in adult ED patients with or without a history of childhood trauma exposure.
Methods
We recruited 35 women with EDs, admitted to the Eating Disorders Center of the Department of Psychiatry of the University of Naples “Luigi Vanvitelli”. Participants filled in the Childhood Trauma Questionnaire (CTQ), to assess exposure to childhood trauma. They were instructed to collect saliva samples at awakening and after 15, 30 and 60 minutes, in order to measure cortisol levels and salivary alpha-amylase (sAA), a marker of the sympathetic nervous system activity.
Results
According to the CTQ cut-off scores, 21 ED women were classified as maltreated (Mal) participants and 14 women as no-maltreated (noMal) ED participants. Compared to noMal ED women, Mal ED participants showed significantly decreased cortisol awakening response (CAR) and sAA morning secretion.
Conclusions
Present findings confirm that childhood trauma exposure impairs the CAR of adult patients with EDs and show that also the morning secretion of sAA is decreased in childhood maltreated adult ED patients. Therefore, our study shows for the first time a dampening in the basal activity of both components of the endogenous stress response system in childhood maltreated adult ED women.
The coronavirus disease 2019 (COVID-19) pandemic and the resulting containment measures, such as “lockdown” and “social distancing”, have had important consequences on people’s mental and physical health.
Objectives
We aimed to study the effect of social isolation and subsequent re- exposure and eventual changes in general and ED-specific psychopathology in people with Eating Disorders (EDs).
Methods
Three-hundred twelve Italian people with EDs (179 Anorexia Nervosa, 83 Bulimia Nervosa, 48 Binge Eating Disorder and 22 Other Specific Feeding Eating Disorder) were asked to fill-in an online survey to explore several dimensions such as: anxiety, depression, panic, insomnia, suicide ideation, stress, post-traumatic stress and obsessive-compulsive symptoms. Differences in ED specific and general symptoms among the 3 investigated time periods (before, during and after the end of lockdown) were assessed with a one-way ANOVA with repeated measures. Subsequently, ED diagnosis was introduced as covariate in the analysis in order to investigate the possible contribution on psychopathological changes.
Results
ED core symptoms increased during the lockdown but most of them returned to pre-COVID19 levels at re-opening. The severity of general psychopathology also increased during the lockdown and persisted high in the following phase, except for depression and suicide ideation. None of this symptoms was affected by ED diagnosis, participants’age and illness duration.
Conclusions
People with EDs showed worsening of both general and specific psychopathology; moreover, changes in general psychopathology persisted in the re-opening period suggesting a higher stress vulnerability in this kind of patients.
There has been a proliferation of research with human participants in violent contexts over the past ten years. Adhering to commonly held ethical principles such as beneficence, justice, and respect for persons is particularly important and challenging in research on violence. This letter argues that practices around research ethics in violent contexts should be reported more transparently in research outputs, and should be seen as a subset of research methods. We offer practical suggestions and empirical evidence from both within and outside of political science around risk assessments, mitigating the risk of distress and negative psychological outcomes, informed consent, and monitoring the incidence of potential harms. An analysis of published research on violence involving human participants from 2008 to 2019 shows that only a small proportion of current publications include any mention of these important dimensions of research ethics.
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.
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.
We present an overview of the Middle Ages Galaxy Properties with Integral Field Spectroscopy (MAGPI) survey, a Large Program on the European Southern Observatory Very Large Telescope. MAGPI is designed to study the physical drivers of galaxy transformation at a lookback time of 3–4 Gyr, during which the dynamical, morphological, and chemical properties of galaxies are predicted to evolve significantly. The survey uses new medium-deep adaptive optics aided Multi-Unit Spectroscopic Explorer (MUSE) observations of fields selected from the Galaxy and Mass Assembly (GAMA) survey, providing a wealth of publicly available ancillary multi-wavelength data. With these data, MAGPI will map the kinematic and chemical properties of stars and ionised gas for a sample of 60 massive (
${>}7 \times 10^{10} {\mathrm{M}}_\odot$
) central galaxies at
$0.25 < z <0.35$
in a representative range of environments (isolated, groups and clusters). The spatial resolution delivered by MUSE with Ground Layer Adaptive Optics (
$0.6-0.8$
arcsec FWHM) will facilitate a direct comparison with Integral Field Spectroscopy surveys of the nearby Universe, such as SAMI and MaNGA, and at higher redshifts using adaptive optics, for example, SINS. In addition to the primary (central) galaxy sample, MAGPI will deliver resolved and unresolved spectra for as many as 150 satellite galaxies at
$0.25 < z <0.35$
, as well as hundreds of emission-line sources at
$z < 6$
. This paper outlines the science goals, survey design, and observing strategy of MAGPI. We also present a first look at the MAGPI data, and the theoretical framework to which MAGPI data will be compared using the current generation of cosmological hydrodynamical simulations including EAGLE, Magneticum, HORIZON-AGN, and Illustris-TNG. Our results show that cosmological hydrodynamical simulations make discrepant predictions in the spatially resolved properties of galaxies at
$z\approx 0.3$
. MAGPI observations will place new constraints and allow for tangible improvements in galaxy formation theory.
Palliative care (PC) is patient and family-centered supportive care intended to improve symptom management, reduce caregiver burden, coordinate care, and improve quality of life for patients diagnosed with serious illness. Optimally, PC is begun close to initial diagnosis and delivered in synchrony with disease-specific treatment until symptom relief or patient death. The purpose of this study was to examine cancer survivors’ knowledge and perceptions of PC using a nationally representative sample of US adults from the Health Information National Trends Survey (HINTS).
Method
A total of 593 HINTS respondents reported a personal history of cancer and were included in the sample (55.56% female; mean age of 65.88 years, SD = 18.21; mean time from diagnosis 13.83 years, SD = 18.21). Weighted logistic regression models were conducted to identify correlates of PC knowledge.
Results
Of the 593 cancer survivors in the sample, 66% (N = 378) reported that they had never heard of PC, 18% (N = 112) reported knowing a little bit about PC, and 17% (N = 95) reported knowing what PC is and could explain it to someone else. In multivariable analysis, survivors of color (Hispanic/Latino, Black, Asian, American Indian, and Pacific Islander), males, and those less educated were significantly less likely to report knowledge of PC. Among survivors who did report knowledge of PC, a lack of distinction between differing modes of supportive care exists.
Significance of results
These findings suggest a need to increase PC knowledge among cancer survivors with the ultimate goal of addressing disparities in PC acceptance and utilization.
Prior to facing the challenges of FM management, an initial diagnosis must be made. To guide general practitioners (GPs) in the early detection of FM in Europe, we developed an easy-to-use screening tool specific to FM.
Method:
A European multidisciplinary expert group was constituted with the aim of providing clinical expertise, defining methodology, and identifying key issues around the detection of FM. Three conceptual models describing factors that may contribute to the identification of FM patients were derived from; a) a comprehensive literature review, 2) clinician focus groups (N=6), and 3) face-to-face interviews with German, French, and English-speaking patients (N=29) conducting by psychologists to explore their attitudes and perceptions of the disease. A FM screening tool was developed in all three languages and tested for comprehension and applicability in FM-diagnosed and FM-suspected patients.
Results:
The models derived from the literature, clinician focus groups, and FM patient interviews showed high consistency. The resulting FM screening tool is comprised of 14 questions that describe patients' pain, fatigue, associated symptoms, impact on everyday life, personal history, and attitudes towards their FM.
Conclusion:
Based on this qualitative study, the detection of FM is likely to require the assessment of multiple psychological factors in addition to symptoms, including patient reporting of personal history and patient behaviour. The quantitative validation of these findings is currently underway.

A prospective study in treatment-resistant schizophrenic patients was performed over 10 years to evaluate the therapeutic response to clozapine and the variables related to this treatment. Eighty schizophrenic and schizoaffective patients (according to Diagnostic and Statistical Manual [DSM]-IIIR criteria), considered as refractory (previously resistant to at least two different typical neuroleptics), were studied. The average dose of clozapine was 267 mg/d. The clinical variables considered were: Brief Psychiatric Rating Scale (BPRS), number of admissions before and after clozapine treatment and the Strauss-Carpenter scale as measures of efficacy; Premorbid Adjustment Scale (PAS), to assess personal and social adjustment before illness; Karolinska Personality Scale (KPS) to assess stable traits of personality; and the Simpson-Angus scale as a measure of extrapyramidal symptoms. Sixty percent of patients showed a significant improvement after clozapine treatment. Side-effects were mild and well tolerated, with no cases of haematological disturbance and only five withdrawals because of adverse events. The severity of the episode, according to BPRS score and anxiety as a personal trait, are related to good prognosis. Other relationships between improvement and clinical and demographic variables are discussed.
Treatment Resistant-Depression (TRD), known as the failure to respond to at least two different adequate trials of antidepressant treatments (ADT) in the current episode, is a relatively frequent clinical condition, associated to a high number of relapses, hospitalizations, and an elevated use of multiple pharmacological treatments. To date, however, the association between clinical variables and non-response in TRD remains unclear.
Objectives
To identify predictors of non-response in inpatients with Major Depressive Disorder (MDD) and TRD.
Aims
To investigate clinical variables as potential predictors of non-response in TRD.
Methods
Two hundred fifty-three inpatients with MDD and TRD were divided into two groups: responders and non-responders to drug therapies, according to a decrease of 50% or more of the severity of depression (measured with HAM-D 17 items) at the end of forth week of hospitalization. A general model of Cox regression (with backward stepwise method) was used to identify independent predictors of non-response to treatment.
Results
One hundred fifty-four TRD inpatients were responders and 99 non-responders. Cox regression identified three independent clinical predictors independently associated with the group of non-responders: (1) the presence of 5 or more depressive episodes in the medical history (OR = 2.27); (2) a current comorbid anxiety disorder (OR = 1.85); (3) a history of early life adversities (ELAs) (OR = 1.60).
Conclusions
The findings of this study suggest that the phenomenon of non-pharmacological response in the TRD is associated with different clinical variables, which might act through separate mechanisms in determining the persistence of depressive symptomatology.
QTc interval prolongation is considered a risk factor for fatal polymorphic ventricular tachycardia, which can result in sudden cardiac death. Most psychotropic drugs have a dose-dependent potential to prolong the QTc interval. However, other factors require appropriate consideration, including: age; gender; other medications; electrolyte abnormalities; severe comorbid conditions, such as co-occurring alcohol or substances abuse/dependence.
Objectives
The objective was to study the potential mediating roles of alcohol/substances abuse on QTc prolongation.
Aims
The Italian research group STAR Network, in collaboration with the Young Italian Psychiatrists Association, aimed to evaluate the frequency of QTc interval prolongation in a sample of patients under treatment with psychotropic drugs through a cross-sectional national survey.
Methods
A sample of 2411 unselected patients were enrolled after performing an ECG during the recruitment period. Sociodemographic and clinical characteristics were collected from medical records. Collected data underwent statistical analysis.
Results
A total of 11.2% of patients reported alcohol abuse, and only 8.9% psychotropic substances. According to the threshold, less than 20% of patients had a borderline value of QTc, and 1% a pathological value. Patients with co-occurring alcohol misuse and drug abuse were more likely to have longer QTc interval.
Conclusions
The present study describes the frequency of QTc prolongation in real-world clinical practice. Before prescribing a psychotropic drug, the physician should carefully assess its risks and benefits to avoid this type of adverse reaction, particularly when additional risk factors are present. The potential role of alcohol and substances on QTc length could be particularly useful in emergency settings.

Efforts to reduce Clostridioides difficile infection (CDI) have targeted transmission from patients with symptomatic C. difficile. However, many patients with the C. difficile organism are carriers without symptoms who may serve as reservoirs for spread of infection and may be at risk for progression to symptomatic C. difficile. To estimate the prevalence of C. difficile carriage and determine the risk and speed of progression to symptomatic C. difficile among carriers, we established a pilot screening program in a large urban hospital.
Design:
Prospective cohort study.
Setting:
An 800-bed, tertiary-care, academic medical center in the Bronx, New York.
Participants:
A sample of admitted adults without diarrhea, with oversampling of nursing facility patients.
Methods:
Perirectal swabs were tested by polymerase chain reaction for C. difficile within 24 hours of admission, and patients were followed for progression to symptomatic C. difficile. Development of symptomatic C. difficile was compared among C. difficile carriers and noncarriers using a Cox proportional hazards model.
Results:
Of the 220 subjects, 21 (9.6%) were C. difficile carriers, including 10.2% of the nursing facility residents and 7.7% of the community residents (P = .60). Among the 21 C. difficile carriers, 8 (38.1%) progressed to symptomatic C. difficile, but only 4 (2.0%) of the 199 noncarriers progressed to symptomatic C. difficile (hazard ratio, 23.9; 95% CI, 7.2–79.6; P < .0001).
Conclusions:
Asymptomatic carriage of C. difficile is prevalent among admitted patients and confers a significant risk of progression to symptomatic CDI. Screening for asymptomatic carriers may represent an opportunity to reduce CDI.
Item 9 of the Patient Health Questionnaire-9 (PHQ-9) queries about thoughts of death and self-harm, but not suicidality. Although it is sometimes used to assess suicide risk, most positive responses are not associated with suicidality. The PHQ-8, which omits Item 9, is thus increasingly used in research. We assessed equivalency of total score correlations and the diagnostic accuracy to detect major depression of the PHQ-8 and PHQ-9.
Methods
We conducted an individual patient data meta-analysis. We fit bivariate random-effects models to assess diagnostic accuracy.
Results
16 742 participants (2097 major depression cases) from 54 studies were included. The correlation between PHQ-8 and PHQ-9 scores was 0.996 (95% confidence interval 0.996 to 0.996). The standard cutoff score of 10 for the PHQ-9 maximized sensitivity + specificity for the PHQ-8 among studies that used a semi-structured diagnostic interview reference standard (N = 27). At cutoff 10, the PHQ-8 was less sensitive by 0.02 (−0.06 to 0.00) and more specific by 0.01 (0.00 to 0.01) among those studies (N = 27), with similar results for studies that used other types of interviews (N = 27). For all 54 primary studies combined, across all cutoffs, the PHQ-8 was less sensitive than the PHQ-9 by 0.00 to 0.05 (0.03 at cutoff 10), and specificity was within 0.01 for all cutoffs (0.00 to 0.01).
Conclusions
PHQ-8 and PHQ-9 total scores were similar. Sensitivity may be minimally reduced with the PHQ-8, but specificity is similar.
To measure the association between receipt of specific infection prevention interventions and procedure-related cardiac implantable electronic device (CIED) infections.
Design:
Retrospective cohort with manually reviewed infection status.
Setting:
Setting: National, multicenter Veterans Health Administration (VA) cohort.
Participants:
Sampling of procedures entered into the VA Clinical Assessment Reporting and Tracking-Electrophysiology (CART-EP) database from fiscal years 2008 through 2015.
Methods:
A sample of procedures entered into the CART-EP database underwent manual review for occurrence of CIED infection and other clinical/procedural variables. The primary outcome was 6-month incidence of CIED infection. Measures of association were calculated using multivariable generalized estimating equations logistic regression.
Results:
We identified 101 procedure-related CIED infections among 2,098 procedures (4.8% of reviewed sample). Factors associated with increased odds of infections included (1) wound complications (adjusted odds ratio [aOR], 8.74; 95% confidence interval [CI], 3.16–24.20), (2) revisions including generator changes (aOR, 2.4; 95% CI, 1.59–3.63), (3) an elevated international normalized ratio (INR) >1.5 (aOR, 1.56; 95% CI, 1.12–2.18), and (4) methicillin-resistant Staphylococcus colonization (aOR, 9.56; 95% CI, 1.55–27.77). Clinically effective prevention interventions included preprocedural skin cleaning with chlorhexidine versus other topical agents (aOR, 0.41; 95% CI, 0.22–0.76) and receipt of β-lactam antimicrobial prophylaxis versus vancomycin (aOR, 0.60; 95% CI, 0.37–0.96). The use of mesh pockets and continuation of antimicrobial prophylaxis after skin closure were not associated with reduced infection risk.
Conclusions:
These findings regarding the real-world clinical effectiveness of different prevention strategies can be applied to the development of evidence-based protocols and infection prevention guidelines specific to the electrophysiology laboratory.
The rate of cardiovascular implantable electronic device (CIED) infection is increasing coincident with an increase in the number of device procedures. Preprocedural antimicrobial prophylaxis reduces CIED infections; however, there is no evidence that prolonged postprocedural antimicrobials additionally reduce risk. Thus, we sought to quantify the harms associated with this approach.
Objective
To measure the association between Clostridium difficile infection (CDI), acute kidney injury (AKI) and receipt of prolonged postprocedural antimicrobials.
Methods
CIED procedures entered into the VA Clinical Assessment Reporting and Tracking Electrophysiology (CART-EP) database during fiscal years 2008–2016 were included. The primary outcome was 90-day incidence of CDI and the secondary outcome was the 7-day incidence of AKI. The primary exposure measure was duration of postprocedural antimicrobial therapy. Associations were measured using Cox-proportional hazards and binomial regression.
Results
Prolonged postprocedural antimicrobial therapy was identified following 3,331 of 6,497 CIED procedures (51.3%), and the median duration of prophylaxis was 5 days. Prolonged postprocedural antimicrobial use was associated with increased risk of CDI (hazard ratio [HR], 2.90; 95% confidence interval [CI], 1.54–5.46). Of the 27 patients who developed CDI, 11 subsequently died. Postprocedural antimicrobial use with ≥2 antimicrobials was associated with an increased risk of AKI (OR, 4.16; 95% CI, 2.50–6.90). The impact was particularly significant when one of the dual agents prescribed was vancomycin (adjusted OR, 8.41; 95% CI, 5.53–12.79).
Conclusions
Prolonged antimicrobial prophylaxis following CIED procedures increases preventable harm; this practice should be discouraged in procedural settings such as the cardiac electrophysiology laboratory.
