Background

Anorexia Nervosa (AN) is a psychiatric disorder that can lead to cardiac complications, especially in severely malnourished patients. Cardiovascular involvement includes autonomic dysfunction (increased vagal tone, bradycardia, orthostatic hypotension, syncope), arrhythmias, pericardial effusion, heart failure and sudden death. A few studies have examined the echocardiographic abnormalities secondary to AN, reporting mainly a decreased cardiac mass and an increased incidence of pericardial effusion. No previous studies examined the changes of Global Longitudinal Strain (GLS), which has been shown to be an early marker of myocardial damage in other subsets.

Purpose

This study aimed to characterize echocardiographic abnormalities in AN, and to assess impairment of global and regional longitudinal strain (LS) and its clinical value in this context.

Methods

We prospectively enrolled 42 consecutive patients (1 male) admitted to a highly specialized AN unit between November 2020 and July 2021 with AN (Mental Disorders, 4th Edition-DSM IVr). We also selected 34 healthy controls, matched for age and sex. In all subjects, we reported the cardiac frequency, systolic and diastolic blood pressure, blood examinations, and we performed an echocardiography, including GLS measurement. Eighteen patients were treated with enteral or parenteral feeding. A subset of 26 AN patients performed a second echocardiography after one month of follow up; 14 of them received forced feeding.

Results

Compared with healthy subjects, AN patients had significantly lower albumin levels (45.1 ± 10.3 vs 66.0 ± 4.8 mg/dl, p = 0.031), lower FT3 levels (3.7 ± 1.0 vs 7.9 ± 6.4 pg/mL, p = 0.001), higher FT4 levels (13.8 ± 1.8 vs 9.6 ± 8.1 pg/mL, p = 0.008), a lower cardiac frequency (63 ± 18 vs 73 ± 12 bpm, p = 0.004), a higher incidence of pericardial effusion (9/42 vs 0/34, p = 0.008), a lower myocardial mass (62.3 ± 15.0 vs 98.5 ± 28.5 g, p < 0.001), a lower absolute value of GLS (-18.8 ± 2.8 vs -20.3 ± 2.0 %, p = 0.014) and basal LS (-15.4 ± 6.1 vs -19.6 ± 2.8 %, p < 0.001). The bull’s eye mapping showed a plot pattern with blue basal areas in 17/42 AN patients vs 1/34 healthy subjects (p < 0.001). The 17 anorexic patients with a blue basal pattern needed forced feeding in a higher proportion (11/17 vs 7/25, p = 0.018) and presented more frequently amenorrhea (14/17 vs 11/25, p = 0.046). During the follow up (26 AN patients performed a second echocardiography), of 13 patients with blue areas in the first bull’s eye mapping, 11 recovered a completely red pattern, and of 13 patients with a red bull’s eye in the first examination, no one presented blue areas on the second one.

Conclusions

GLS is significantly altered in AN patients and a basal blue pattern on bull’s eye mapping individuates more severe cases. These changes seem to be reversible (Figure 1), although further studies are necessary to understand which factors influence this pattern besides BMI. Abstract Figure 1

Periodicities in the Daily Proton Fluxes from 2011 to 2019 Measured by the Alpha Magnetic Spectrometer on the International Space Station from 1 to 100 GV

We present the precision measurement of the daily proton fluxes in cosmic rays from May 20, 2011 to October 29, 2019 (a total of 2824 days or 114 Bartels rotations) in the rigidity interval from 1 to 100 GV based on 5.5×10^{9} protons collected with the Alpha Magnetic Spectrometer aboard the International Space Station. The proton fluxes exhibit variations on multiple timescales. From 2014 to 2018, we observed recurrent flux variations with a period of 27 days. Shorter periods of 9 days and 13.5 days are observed in 2016. The strength of all three periodicities changes with time and rigidity. The rigidity dependence of the 27-day periodicity is different from the rigidity dependences of 9-day and 13.5-day periods. Unexpectedly, the strength of 9-day and 13.5-day periodicities increases with increasing rigidities up to ∼10  GV and ∼20  GV, respectively. Then the strength of the periodicities decreases with increasing rigidity up to 100 GV.

Properties of a New Group of Cosmic Nuclei: Results from the Alpha Magnetic Spectrometer on Sodium, Aluminum, and Nitrogen

We report the properties of sodium (Na) and aluminum (Al) cosmic rays in the rigidity range 2.15 GV to 3.0 TV based on 0.46 million sodium and 0.51 million aluminum nuclei collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. We found that Na and Al, together with nitrogen (N), belong to a distinct cosmic ray group. In this group, we observe that, similar to the N flux, both the Na flux and Al flux are well described by the sums of a primary cosmic ray component (proportional to the silicon flux) and a secondary cosmic ray component (proportional to the fluorine flux). The fraction of the primary component increases with rigidity for the N, Na, and Al fluxes and becomes dominant at the highest rigidities. The Na/Si and Al/Si abundance ratios at the source, 0.036±0.003 for Na/Si and 0.103±0.004 for Al/Si, are determined independent of cosmic ray propagation.

Measurement of the Iron Spectrum in Cosmic Rays from 10 GeV/n to 2.0 TeV/n with the Calorimetric Electron Telescope on the International Space Station

The Calorimetric Electron Telescope (CALET), in operation on the International Space Station since 2015, collected a large sample of cosmic-ray iron over a wide energy interval. In this Letter a measurement of the iron spectrum is presented in the range of kinetic energy per nucleon from 10  GeV/n to 2.0  TeV/n allowing the inclusion of iron in the list of elements studied with unprecedented precision by space-borne instruments. The measurement is based on observations carried out from January 2016 to May 2020. The CALET instrument can identify individual nuclear species via a measurement of their electric charge with a dynamic range extending far beyond iron (up to atomic number Z=40). The energy is measured by a homogeneous calorimeter with a total equivalent thickness of 1.2 proton interaction lengths preceded by a thin (3 radiation lengths) imaging section providing tracking and energy sampling. The analysis of the data and the detailed assessment of systematic uncertainties are described and results are compared with the findings of previous experiments. The observed differential spectrum is consistent within the errors with previous experiments. In the region from 50  GeV/n to 2  TeV/n our present data are compatible with a single power law with spectral index -2.60±0.03.

Anxiety disorders and childhood exposure to emotional abuse: The mediating role of disgust

Introduction

Several studies demonstrate that disgust, defined as a revulsion response aimed at distancing an individual from a potentially harmful or noxious stimulus, is linked to post-traumatic stress following sexual trauma even when accounting for associated fear and anxiety. One of the suggested mechanisms implicated in this association is a feeling of mental contamination. Recent neuroimaging studies demonstrated that exposure to contamination activates the insular cortex. In addition, disgust sensitivity correlates with the activation of the insular cortex.

Objectives

We aimed to investigate the psychopathological role of the emotion of disgust in the developement of anxiety symptoms in patient with an history of abuse.

Methods

We enrolled 84 patients admitted in Psychiatric Unit of Careggi with diagnosis of Anxiety Disorders. We administered to them: Zung Anxiety Scale (ZSAS), Childhood Trauma Questionnaire (CTQ), Disgust Propensity and Sensitivity Scale-revised (DPSS-r).

Results

Results showed a significant mediation of the association between CTQ emotional abuse scores and total ZSAS scores via DPSS disgust sensitivity scores in patients with anxiety disorders (p=0.022). Total effect and indirect effect of emotional abuse on severity of anxiety symptoms were significant (total effect = 0.494; p=0.051, indirect effect: 0.256, p=0.022), while there was no significant direct effect from emotional abuse to anxiety symptoms in the total model (direct effect: 0.237, p=0.356). The model explained 18% of variance in anxiety symptomatology (R²=0.18).

Conclusions

Such preliminary data suggest a possible mediating role of disgust in development and maintenance of childhood abuse-related anxiety, making it a potential target for psychotherapy.

Clinical, psychopathological, and biological predictors of resumption of menses in subjects with anorexia nervosa: A 4-year follow-up study

Introduction

Amenorrhea is one of the most frequent and serious consequences of Anorexia Nervosa (AN). Resumption of menses (ROM) is considered an important goal and is associated with a better outcome.

Objectives

To investigate the role of age, Body Mass Index (BMI), diagnostic subtype (restrictive vs binge-purging), history of childhood abuse, duration of illness, psychopathology and sex hormones on ROM in AN.

Methods

52 patients with AN and amenorrhea were enrolled at the start of treatment. Clinical parameters of interest were collected, and questionnaires were administered for the assessment of general (SCL-90-R) and specific (EDE-Q) psychopathology. Blood samples were taken to assess FSH, LH and estradiol levels. All patients were monitored regularly through psychiatric checkups until ROM, for up to four years.

Results

A total of 30 (57.7%) subjects recovered their menstrual cycle in the follow-up period (mean time: 18.7 ± 14.8 months). Recovery was more frequent in the binge-purging subtype than in the restrictive subtype (82.4% vs 48.6%, p=0.019), and was significantly associated with diagnostic crossover (odds ratio=10.0, p=0.032). Multivariate Cox regression showed an increased likelihood of menstrual recovery for binge-purging subtype (p=0.005) and for those reporting a history of childhood abuse (p=0.025). Early ROM was also associated with baseline SCL-90-R scores (p=0.002) and FSH (p=0.011), while a longer duration of illness (p=0.003) and EDE-Q scores (p=0.009) predicted a later recovery.

Conclusions

This study highlights the role of duration of illness, childhood abuse history and psychopathological characteristics in subjects with AN at the start of treatment in predicting ROM.

Anxiety disorders and eating disorder symptoms: The role of disgust sensitivity

Introduction

The comorbidity between anxiety disorders (AD) and eating disorders (ED) has already been well discovered, and because of the link between disgust, food choice and rejection (which appear to be key factors of eating psychopathology), it can be suggested that these three aspects may be related. Accordingly, it can be hypothesized that individuals who express heightened levels of both disgust and eating concerns are at a higher risk to develop an AD. By contrast, disgust, as a negative emotion, influences ED symptoms through a greater level of anxiety.

Objectives

We aimed to investigate the psychopathological role of disgust and eating disorder symptoms in the development and maintenance of anxiety symptoms in patients with AD.

Methods

We enrolled 84 patients admitted in the Psychiatric Unit of Careggi with diagnosis of Anxiety Disorders. We administered them: Zung Anxiety Scale (ZSAS), Disgust Propensity and Sensibility Scale-revised (DPSS-r) and Eating Disorders Examination Questionnaire (EDE-Q).

Results

A multiple regression model having ZSAS total as dependent variable, and EDE-Q total and DPSS disgust sensitivity subscale as independent variables explained 29% of ZSAS total variance (R²=0.290). The effect of EDE-Q total was positive, significant (β=0.331, t=2.631, p=0.011) and explained 11.9% of ZSAS total variance (pr²=0.119). The effect of DPSS disgust sensitivity was positive, significant (β=0.326, t=2.595, p=0.012) and explained 11.6% of ZSAS total variance (pr²=0.116) (Fig.1).

Conclusions

Such preliminary data suggest a possible role of feelings of disgust and eating disorder symptoms in development and maintenance of anxiety symptoms in patients with AD, making them a potential target for psychotherapy.

The impact of COVID-19 on eating disorders: A longitudinal study with assessments before and after the lockdown

Introduction

The COVID-19 epidemic that spread in Italy in the early 2020, together with the general lockdown, are high-risk events for vulnerable populations who need high levels of assistance, such as patients with eating disorders (EDs).

Objectives

To evaluate the impact of the COVID-19 epidemic and lockdown on subjects suffering from EDs, considering previous vulnerabilities.

Methods

74 patients with anorexia nervosa (AN) or bulimia nervosa (BN) already on treatment and 97 healthy controls were evaluated between November 2019/January 2020 (T1), and again in April 2020, 6 weeks after the start of lockdown (T2). Patients were also evaluated at baseline (T0). At each assessment, general and ED psychopathology (SCL-90-R and EDE-Q) were assessed. Childhood abuse experiences (CTQ) and adult attachment (ECR-R) were investigated at T1, and post-traumatic stress symptoms (IES-R) at T2.

Results

Patients reported a significant increase in compensatory exercise; in addition, patients with BN and those who achieved remission at T1 showed a significant exacerbation of binge-eating. The longitudinal trend (T1-T2) of psychopathology was not different between patients and controls, however the expected benefit from treatment on ED psychopathology was significant only for AN, while no changes were noted in BN. Patients with BN reported more severe post-traumatic stress symptoms than AN and controls, and these symptoms correlated positively with prior traumatic experiences and an insecure attachment style.

Conclusions

The COVID-19 epidemic and lockdown had a significant impact on subjects with eating disorders, both by interfering with the treatment process and in terms of post-traumatic stress symptoms.

Dysregulated sexuality and childhood trauma in eating disorders: Psychopathological, biological, and behavioural correlates

Introduction

Sexual dysfunction is common in eating disorders (EDs), but its relevance is often overlooked.

Objectives

To describe different ED clinical subgroups in terms of psychopathology, putative biological correlates, and consequences of dysregulated sexuality, focusing on the role of childhood trauma.

Methods

Healthy controls (n=60), binge-purging (n=38), and restricting patients (n=24) were compared (age- and BMI-adjusted ANOVA; Bonferroni post-hoc tests), using total scores of Eating Disorder Examination Questionnaire (EDE-Q), Emotional Eating Scale (EES), SCL-90-R Global Severity Index (GSI), Barratt Impulsiveness Scale (BIS-11), Difficulties in Emotion Regulation Scale (DERS), Childhood Trauma Questionnaire (CTQ), Female Sexual Functioning Index (FSFI), Hypersexual Behaviour Inventory (HBI), and patients’ hormonal profiles (gonadal and pituitary hormones, ghrelin). Self-reported voluntary termination of pregnancy (VTP) and promiscuous sexual activity were recorded. For ED patients (N=62), regression analyses between significant variables and HBI were carried, applying moderation models for different CTQ scores.

Results

Table 1 outlines significant between-group comparisons (°: different from controls; *: different from restricting patients; p<0.05). Binge-purging patients had higher FSH, LH, and ghrelin levels, more VTPs and promiscuity. HBI showed significant correlations with EES, SCL-90-R-GSI, DERS, CTQ, and ghrelin levels. CTQ moderated interactions for DERS and EES (Figure 1).

	Binge-purging	Restricting	Controls	F
EDE-Q	3.86±1.20°	3.41±1.64°	0.85±0.83	67.32
EES	40.85±22.74°*	16.01±15.88	19.87±15.21	7.01
SCL-90-R GSI	1.73±0.65°	1.27±0.69°	0.68±0.44	20.32

HBI	28.75±13.89*	20.56±3.12	26.11±4.90	4.92

Conclusions

Dysregulated sexuality is linked to emotion dysregulation and childhood trauma. Binge-purging patients experience adverse behavioural consequences.

Transdiagnostic effect of contamination disgust on asceticism

Introduction

There is a growing literature suggesting disgust plays a major role in religiosity. Asceticism is a personality trait characterized by abstinence from sensual pleasures, often for the purpose of pursuing spiritual goals. Since few studies suggested that higher disgust levels may lead to greater fear of sin, contamination disgust may serve as effective mechanisms for inflated scrupulosity.

Objectives

We aimed to investigate the role of contamination disgust on a specific religious belief in two clinical groups: eating disorders and anxiety disorders.

Methods

We enrolled 84 patients admitted in the Psychiatric Unit of Careggi with diagnosis of Anxiety Disorders (AD) and Eating Disorders (ED). We administered them: Disgust Scale Revised (DS-R) and Eating Disorders Inventory 2 (EDI-2)

Results

A t-test for independent samples between AD patients and ED patients showed no difference in DS-R contamination disgust subscale (t=1.437, p=0.153), while significantly higher EDI-2 asceticism scores were detected in ED patients (t=2.452, p=0.010). An ANCOVA model having EDI2 Asceticism subscale as dependent variable, and DS contamination disgust subscale, diagnosis, and interaction between contamination disgust and diagnosis was estimated. The overall model was significant (F(1,136)=4.854, p=0.003) and accounted for 9.7% of variance of EDI2 Asceticism subscale (R²=0.097). The effect of contamination disgust was positive and significant (β=0.302, t=2.781, p=0.006), and accounted for 5.4% of variance of EDI2 Asceticism (partial η²=0.054). No effect was detected for diagnosis (F(1,136)=0.012, p=0.912) or interaction between contamination disgust and diagnosis (F(1,136)=1.346, p=0.248).

Conclusions

Contamination disgust may have a trans-diagnostic effect on asceticism and may be a possible driver for specific religious behaviors.

COVID-19 pandemic and eating disorders: What impact on specific and general psychopathology?

Introduction

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.

Psychopathology in adult transgender people

Transgender people represent a broad spectrum of individuals that transiently or persistently identify with a gender different from the one assigned at birth (APA, 2013). Transgender healthcare issues have become an increased matter of interest over the last years, as shown by the growth of publications on the subject and by the increase of referrals reported worldwide in all age groups. However, transgender people report encountering numerous obstacles in accessing and receiving appropriate health care with professionals being described as not properly trained on specific gender issues. Considering the diversity and complexity of the gender spectrum in the different age groups and in light of the recent changes in the formal psychiatric classification, mental health providers play a critical role in meeting the needs of gender non-conforming children, adolescents and adults, according to individualized paths. This course has the following aims: (1) learn the principles of assessment of gender incongruence in childhood, adolescence and adulthood; (2) address co-occurring psychopathology (if present); (3) identify different treatment paths according to age and individualized psychological and/or medical needs; (4) work in a multidisciplinary team in line with an integrated model.

Psychopathological consequences and dysfunctional behaviours during the COVID-19 epidemic in italy: A longitudinal study before and after the lockdown

Introduction

In the first months of 2020 the COVID-19 epidemic spread in Italy, and the Italian government implemented a general lockdown. These events are at high risk for psychiatric symptoms in the general population, including anxiety/depression and post-traumatic stress symptoms (PTSS).

Objectives

To characterize the psychopathological correlates of the spread of COVID-19 and lockdown in a sample of subjects from the Italian population, with a before-after follow-up.

Methods

Six weeks after the lockdown, 671 subjects aged 18-60 years completed the Brief Symptom Inventory and Impact of Event Scale-Revised, for the evaluation of psychopathology and PTSS respectively. Environmental factors and subjectively-perceived deteriorations related to COVID-19 were also investigated. Pre-COVID-19 data on psychopathology, collected in December 2019/January 2020, were available for 130 subjects and were used for longitudinal analyses.

Results

With respect to males, female subjects more frequently reported deteriorations of relations (21.5% vs 10.9%), household arguments (26.0% vs 12.6%), sleep quality (47.6% vs 26.6%), episodes of overeating (22.5% vs 12.5%), worries for oneself (19% vs 8.9%) and for loved ones (55.7% vs 36.5%). These changes were associated with increased psychopathology, PTSS, and numerous environmental conditions, including significant economic damage from COVID-19/lockdown. Longitudinal analyses showed an increase in phobic anxiety in the whole sample, and in depression for female subjects only, following the spread of COVID-19. Pre-existing psychopathology was a significant predictor of PTSS.

Conclusions

COVID-19 epidemic and lockdown have a high impact on psychopathology and PTSS. Female subjects and those with pre-existing psychopathology were found to be more vulnerable and may need additional support.

Properties of Heavy Secondary Fluorine Cosmic Rays: Results from the Alpha Magnetic Spectrometer

Precise knowledge of the charge and rigidity dependence of the secondary cosmic ray fluxes and the secondary-to-primary flux ratios is essential in the understanding of cosmic ray propagation. We report the properties of heavy secondary cosmic ray fluorine F in the rigidity R range 2.15 GV to 2.9 TV based on 0.29 million events collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. The fluorine spectrum deviates from a single power law above 200 GV. The heavier secondary-to-primary F/Si flux ratio rigidity dependence is distinctly different from the lighter B/O (or B/C) rigidity dependence. In particular, above 10 GV, the F/Si/B/O ratio can be described by a power law R^{δ} with δ=0.052±0.007. This shows that the propagation properties of heavy cosmic rays, from F to Si, are different from those of light cosmic rays, from He to O, and that the secondary cosmic rays have two classes.

Properties of Iron Primary Cosmic Rays: Results from the Alpha Magnetic Spectrometer

We report the observation of new properties of primary iron (Fe) cosmic rays in the rigidity range 2.65 GV to 3.0 TV with 0.62×10^{6} iron nuclei collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. Above 80.5 GV the rigidity dependence of the cosmic ray Fe flux is identical to the rigidity dependence of the primary cosmic ray He, C, and O fluxes, with the Fe/O flux ratio being constant at 0.155±0.006. This shows that unexpectedly Fe and He, C, and O belong to the same class of primary cosmic rays which is different from the primary cosmic rays Ne, Mg, and Si class.

Direct Measurement of the Cosmic-Ray Carbon and Oxygen Spectra from 10 GeV/n to 2.2 TeV/n with the Calorimetric Electron Telescope on the International Space Station

In this paper, we present the measurement of the energy spectra of carbon and oxygen in cosmic rays based on observations with the Calorimetric Electron Telescope on the International Space Station from October 2015 to October 2019. Analysis, including the detailed assessment of systematic uncertainties, and results are reported. The energy spectra are measured in kinetic energy per nucleon from 10  GeV/n to 2.2  TeV/n with an all-calorimetric instrument with a total thickness corresponding to 1.3 nuclear interaction length. The observed carbon and oxygen fluxes show a spectral index change of ∼0.15 around 200  GeV/n established with a significance >3σ. They have the same energy dependence with a constant C/O flux ratio 0.911±0.006 above 25  GeV/n. The spectral hardening is consistent with that measured by AMS-02, but the absolute normalization of the flux is about 27% lower, though in agreement with observations from previous experiments including the PAMELA spectrometer and the calorimetric balloon-borne experiment CREAM.

Are clinical practice guidelines for low back pain interventions of high quality and updated? A systematic review using the AGREE II instrument

BACKGROUND

Clinical practice guidelines (CPGs) provide recommendations for practice, but the proliferation of CPGs issued by multiple organisations in recent years has raised concern about their quality. The aim of this study was to systematically appraise CPGs quality for low back pain (LBP) interventions and to explore inter-rater reliability (IRR) between quality appraisers. The time between systematic review search and publication of CPGs was recorded.

METHODS

Electronic databases (PubMed, Embase, PEDro, TRIP), guideline organisation databases, websites, and grey literature were searched from January 2016 to January 2020 to identify GPCs on rehabilitative, pharmacological or surgical intervention for LBP management. Four independent reviewers used the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool to evaluate CPGs quality and record the year the CPGs were published and the year the search strategies were conducted.

RESULTS

A total of 21 CPGs met the inclusion criteria and were appraised. Seven (33%) were broad in scope and involved surgery, rehabilitation or pharmacological intervention. The score for each AGREE II item was: Editorial Independence (median 67%, interquartile range [IQR] 31-84%), Scope and Purpose (median 64%, IQR 22-83%), Rigour of Development (median 50%, IQR 21-72%), Clarity and Presentation (median 50%, IQR 28-79%), Stakeholder Involvement (median 36%, IQR 10-74%), and Applicability (median 11%, IQR 0-46%). The IRR between the assessors was nearly perfect (interclass correlation 0.90; 95% confidence interval 0.88-0.91). The median time span was 2 years (range, 1-4), however, 38% of the CPGs did not report the coverage dates for systematic searches.

CONCLUSIONS

We found methodological limitations that affect CPGs quality. In our opinion, a universal database is needed in which guidelines can be registered and recommendations dynamically developed through a living systematic reviews approach to ensure that guidelines are based on updated evidence.

Patient health engagement model: explaining citizens noncompliance and maladaptive behaviors

Background

At the end of February 2020 a new case was diagnosed with COVID-19 in north Italy, suddenly followed by new cases. Italian health authorities decided to enforce restrictive measures. Northern areas of Italy were identified as “red areas” to slow down the epidemic and its impact on the healthcare system. From this perspective, the COVID-19 epidemic in Italy constitutes a testing ground for the assessment of the ability of consumers to cope with this health risk.

Methods

A cross-sectional study on a representative sample of 1000 Italian citizens was conducted over the period 27 February- 5 March exploring the following hypotheses: 1) less engaged individuals are more concerned for the health emergency and feel more vulnerable; 2) less engaged have higher probability to develop negative attitudes and dysfunctional behaviors.

Results

only the 16% the interviewees presented a high level of engagement. Lower levels of engagement were measured in the southern parts of Italy (not yet touched by the epidemics at the time of data collection). People with lowers levels of engagement reported higher fears for the contagion and sense of vulnerability. Furthermore, they showed the lower levels of trust in the Public Health Authorities, in medical research and in vaccines. Finally, they appeared more dismissive in their preventive behaviors and more disorganized in the fruition of the healthcare services.

Conclusions

A psychological analysis of processes of attitudinal and role change in the direction of becoming more engaged in health prevention is worthy in order to forecast potential dysfunctional reactions to restrictive health prevention measures and to orient personalized education initiatives to consumers with different level of engagement.

Key messages

Profiling based on the levels of health engagement is important in order to plan more effective healthcare measures during epidemics.

Targeted educational initiatives should take into account citizens' engagement profiles.

Properties of Neon, Magnesium, and Silicon Primary Cosmic Rays Results from the Alpha Magnetic Spectrometer

We report the observation of new properties of primary cosmic rays, neon (Ne), magnesium (Mg), and silicon (Si), measured in the rigidity range 2.15 GV to 3.0 TV with 1.8×10^{6}  Ne, 2.2×10^{6}  Mg, and 1.6×10^{6}  Si nuclei collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. The Ne and Mg spectra have identical rigidity dependence above 3.65 GV. The three spectra have identical rigidity dependence above 86.5 GV, deviate from a single power law above 200 GV, and harden in an identical way. Unexpectedly, above 86.5 GV the rigidity dependence of primary cosmic rays Ne, Mg, and Si spectra is different from the rigidity dependence of primary cosmic rays He, C, and O. This shows that the Ne, Mg, and Si and He, C, and O are two different classes of primary cosmic rays.

Functional neuroimaging in anorexia nervosa: A clinical approach

Aims

To provide a review of the available literature about the functional neuroimaging of anorexia nervosa, and to summarize the possible role of neurobiological factors in its pathogenesis.

Methods

A systematic review of the literature was performed using PubMed and Medline electronic database (1950–September 2009). Eligible studies were restricted to those involving the main parameters of cerebral activity and functional neuroimaging techniques. Findings of the reviewed studies have been grouped on a diagnostic subtype basis, and their comparison has been interpreted in terms of concordance.

Results

We found a high level of concordance among available studies with regard to the presence of frontal, parietal and cingulate functional disturbances in both anorexia nervosa restricting and binge/purging subtypes. Concordance among studies conducted regardless of the anorexia nervosa subtypes suggests an alteration in temporal and parietal functions and striatal metabolism.

Conclusions

The most consistent alterations in anorexia nervosa cerebral activity seem to involve the dorsolateral prefrontal cortex, the inferior parietal lobule, the anterior cingulate cortex and the caudate nucleus. They may affect different neural systems such as the frontal visual system, the attention network, the arousal and emotional processing systems, the reward processing network, and the network for the body schema.

How to early recognize mood disorders in primary care: A nationwide, population-based, cohort study

Background

Mood disorders are managed predominantly in primary care. However, general practitioners’ (GPs) ability to detect and diagnose patients with mood disorders is still considered unsatisfactory. The aim of the present study was to identify predictors for the early recognition of depressive disorder (DD) and bipolar disorder (BD) in general practice.

Methods

A cohort of 1,144,622 patients (605,285 women, 539,337 men) was investigated, using the Health Search IMS Health Longitudinal Patient Database. Predictors of DD or BD were identified at baseline encompassing somatization-related features, lifestyle variables, medical and psychiatric comorbidities. Patients were followed up as long as the following events occurred: diagnoses of DD or BD, death, end of the registration with the GP, end of the study period.

Results

We found an incidence rate of DD or BD of 53.61 and 1.5 per 10,000 person-years, respectively. For both the conditions, the incidence rate grew with age. Most of the lifestyle variables and medical comorbidities increased the risk of mood disorders. The strongest effect was found for migraine/headache (HR [95% CI] = 1.32 [1.26–1.38]), fatigue (1.32 [1.25–1.39]) irritable bowel syndrome (1.15 [1.08-1.23]), and pelvic inflammation disease (1.28 [1.18–1.38]).

Conclusions

Several predictors, in particular somatic symptoms, could be interpreted as an early sign of a mood disorder, and represent a valid indication for the GPs diagnostic process of mental disorders.

The disorder of lived corporeality: A possible link between attachment style and eating disorder psychopathology

Introduction

According to the trans-diagnostic perspective, disturbances in eating patterns of eating disorders (EDs) are considered as epiphenomena secondary to the patient's overvaluation of his/her body shape and weight.

Objectives

The phenomenological theory states that the main feature of ED psychopathology is a disturbance in the way affected persons experience their own body (embodiment). Insecure attachment may promote the development of unstable self-identity leading to use body weight as a source of self-definition.

Aims

The aim of our study was to assess the role of embodiment impairments in the relationships between attachment stiles and ED psychopathology.

Methods

One hundred twelve ED patients and 108 healthy subjects filled in the Identity and Eating Disorders (IDEA) questionnaire, which assesses embodiment and personal identity abnormalities, the eating disorder inventory-2 (EDI-2) and the experiences in close relationships (ECR) scale, which defines attachment styles.

Results

ED patients showed IDEA, EDI-2 and ECR scores significantly higher than controls. Significant correlations between IDEA scores, insecure attachment and almost all EDI-2 sub-item scores emerged in ED patients but not in controls. IDEA total score mediated the relationship between avoidant attachment and EDI-2 interoceptive awareness.

Conclusions

These findings demonstrate that in ED patients insecure attachment is correlated to disorder of identity and lived corporeality that, in turn, mediates the association between attachment and a specific ED psychopathological trait. Therefore, we suppose that early relationships, through the development of disturbances in identity and embodiment, lead to altered perception of bodily signals and deranged discrimination of one's emotions, which could contribute to EDs.
