Abstract
BACKGROUND & AIMS Hepatitis delta virus (HDV) is a satellite RNA virus that requires the hepatitis B virus (HBV) for assembly and propagation. Individuals infected with HDV progress to advanced liver disease faster than HBV-monoinfected individuals. Recent studies have estimated the global prevalence of anti-HDV antibodies among the HBV-infected population to be 5-15%. This study aimed to better understand HDV prevalence at the population level in 25 countries/territories. METHODS We conducted a literature review to determine the prevalence of anti-HDV and HDV RNA in hepatitis B surface antigen (HBsAg)-positive individuals in 25 countries/territories. Virtual meetings were held with experts from each setting to discuss the findings and collect unpublished data. Data were weighted for patient segments and regional heterogeneity to estimate the prevalence in the HBV-infected population. The findings were then combined with The Polaris Observatory HBV data to estimate the anti-HDV and HDV RNA prevalence in each country/territory at the population level. RESULTS After adjusting for geographical distribution, disease stage and special populations, the anti-HDV prevalence among the HBsAg+ population changed from the literature estimate in 19 countries. The highest anti-HDV prevalence was 60.1% in Mongolia. Once adjusted for the size of the HBsAg+ population and HDV RNA positivity rate, China had the highest absolute number of HDV RNA+ cases. CONCLUSIONS We found substantially lower HDV prevalence than previously reported, as prior meta-analyses primarily focused on studies conducted in groups/regions that have a higher probability of HBV infection: tertiary care centers, specific risk groups or geographical regions. There is large uncertainty in HDV prevalence estimates. The implementation of reflex testing would improve estimates, while also allowing earlier linkage to care for HDV RNA+ individuals. The logistical and economic burden of reflex testing on the health system would be limited, as only HBsAg+ cases would be screened. IMPACT AND IMPLICATIONS There is a great deal of uncertainty surrounding the prevalence of hepatitis delta virus among people living with hepatitis B virus at the population level. In this study, we aimed to better understand the burden in 25 countries and territories, to refine techniques that can be used in future analyses. We found a lower prevalence in the majority of places studied than had been previously reported. These data can help inform policy makers on the need to screen people living with hepatitis B virus to find those coinfected with hepatitis delta virus and at high risk of progression, while also highlighting the pitfalls that other researchers have often fallen into.

Abstract
BACKGROUND The 2016 World Health Assembly endorsed the elimination of hepatitis B virus (HBV) infection as a public health threat by 2030; existing therapies and prophylaxis measures make such elimination feasible, even in the absence of a virological cure. We aimed to estimate the national, regional, and global prevalence of HBV in the general population and among children aged 5 years and younger, as well as the rates of diagnosis, treatment, prophylaxis, and the future burden globally. METHODS In this modelling study, we used a Delphi process with data from literature reviews and interviews with country experts to quantify the prevalence, diagnosis, treatment, and prevention measures for HBV infection. The PRoGReSs Model, a dynamic Markov model, was used to estimate the country, regional, and global prevalence of HBV infection in 2022, and the effects of treatment and prevention on disease burden. The future incidence of morbidity and mortality in the absence of additional interventions was also estimated at the global level. FINDINGS We developed models for 170 countries which resulted in an estimated global prevalence of HBV infection in 2022 of 3·2% (95% uncertainty interval 2·7-4·0), corresponding to 257·5 million (216·6-316·4) individuals positive for HBsAg. Of these individuals, 36·0 million were diagnosed, and only 6·8 million of the estimated 83·3 million eligible for treatment were on treatment. The prevalence among children aged 5 years or younger was estimated to be 0·7% (0·6-1·0), corresponding to 5·6 million (4·5-7·8) children with HBV infection. Based on the most recent data, 85% of infants received three-dose HBV vaccination before 1 year of age, 46% had received a timely birth dose of vaccine, and 14% received hepatitis B immunoglobulin along with the full vaccination regimen. 3% of mothers with a high HBV viral load received antiviral treatment to reduce mother-to-child transmission. INTERPRETATION As 2030 approaches, the elimination targets remain out of reach for many countries under the current frameworks. Although prevention measures have had the most success, there is a need to increase these efforts and to increase diagnosis and treatment to work towards the elimination goals.

Abstract
BACKGROUND Studies increasingly suggest that chronic exposure to psychological stress can lead to health deterioration and accelerated ageing, thus possibly contributing to the development of frailty. Recent approaches based on the deficit accumulation model measure frailty on a continuous grading through the "Frailty Index" (FI), i.e. a macroscopic indicator of biological senescence and functional status. OBJECTIVES The study aimed at testing the relationship of FI with caregiving, psychological stress, and psychological resilience. DESIGN Cross-sectional study, with case-control and correlational analyses. PARTICIPANTS Caregivers of patients with dementia (n=64), i.e. individuals a priori considered to be exposed to prolonged psychosocial stressors, and matched controls (n=64) were enrolled. MEASUREMENTS The two groups were compared using a 38-item FI condensing biological, clinical, and functional assessments. Within caregivers, the association of FI with Perceived Stress Scale (PSS) and Brief Resilience Scale (BRS) was tested. RESULTS Caregivers had higher FI than controls (F=8.308, p=0.005). FI was associated directly with PSS (r=0.660, p<0.001) and inversely with BRS (r=-0.637, p<0.001). Findings remained significant after adjusting for certain confounding variables, after excluding from the FI the conditions directly related to psychological stress, and when the analyses were performed separately among participants older and younger than 65 years. CONCLUSIONS The results provide insight on the relationship of frailty with caregiving, psychological stress, and resilience, with potential implications for the clinical management of individuals exposed to chronic emotional strain.

Abstract
Hepatitis A virus (HAV) is an emerging public health concern and there is an urgent need for ways to rapidly identify cases so that outbreaks can be managed effectively. Conventional testing for HAV relies on anti-HAV IgM seropositivity. However, studies estimate that 10–30% of patients may not be diagnosed by serology. Molecular assays that can directly detect viral nucleic acids have the potential to improve diagnosis, which is key to prevent the spread of infections. In this study, we developed a real-time PCR (RT-PCR) assay to detect HAV RNA for the identification of acute HAV infection. Primers were designed to target the conserved 5′-untranslated region (5′-UTR) of HAV, and the assay was optimized on both the Qiagen Rotor-Gene and the BD MAX. We successfully detected HAV from patient serum and stool samples with moderate differences in sensitivity and specificity depending on the platform used. Our results highlight the clinical utility of using a molecular assay to detect HAV from various specimen types that can be implemented in hospitals to assist with diagnostics, treatment and prevention.

Abstract
BACKGROUND Treatment for infection with hepatitis C virus (HCV) during pregnancy has not yet been approved; however, interventions specifically targeting women, especially those of childbearing age (15-49 years), could prevent vertical transmission and community spread. To assess the impact of such interventions, improved prevalence estimates in this group are needed. We aimed to estimate the global prevalence of viraemic HCV in 2019 among women of childbearing age. METHODS In this modelling study, we used previously developed models for 110 countries inputted with country-specific demographic and HCV epidemiology data. We did a literature review, searching PubMed, Embase, and grey literature for studies published between Jan 1, 2000, and June 30, 2018, reporting HCV antibody or viraemic prevalence in women of childbearing age. Studies from the literature review and studies in models were compared by use of a data quality scoring system and models were updated, as appropriate, when a better study was identified. We used these HCV disease burden models to calculate the 2019 prevalence of viraemic HCV in women of childbearing age. In countries without a model, prevalence was extrapolated by Global Burden of Disease (GBD) region. FINDINGS An estimated 14 860 000 (95% uncertainty interval [UI] 9 667 000-18 282 000) women aged 15-49 years had HCV infection worldwide in 2019, corresponding to a viraemic prevalence of 0·78% (95% UI 0·62-0·86). Globally, HCV prevalence increased with age, rising from 0·25% (95% UI 0·20-0·27) in women aged 15-19 years to 1·21% (0·97-1·34) in women aged 45-49 years. China (16% of total infections) and Pakistan (15%) had the greatest numbers of viraemic infections, but viraemic prevalence was highest in Mongolia (5·14%, 95% CI 3·46-6·28) and Burundi (4·91%, 3·80-18·75). Of the countries with 500 cases or more, viraemic prevalence was lowest in Chile (0·07%, 95% UI 0·04-0·12). Among the GBD regions, eastern Europe had the highest viraemic prevalence (3·39%, 95% UI 1·88-3·54). By WHO region, the Eastern Mediterranean region had the highest viraemic prevalence (1·75%, 95% UI 1·26- 1·90). INTERPRETATION Most research on HCV disease burden among women aged 15-49 years focuses on pregnant women. Using modelling, this analysis provides global and national estimates of HCV prevalence in all women of childbearing age. These data can inform preconception test-and-treat strategies to reduce vertical transmission and total disease burden. FUNDING Gilead Sciences, John C Martin Foundation, private donors.

Abstract
Background:Clinical and experimental findings suggest that Obsessive-Compulsive Disorder (OCD) is due to an abnormality of the cortico-striato-thalamo-cortical circuit. Bradykinesia and mental slowness can be present in patients with basal ganglia disorders affecting the cortico-striato-thalamo-cortical circuit. Aim of this study is to investigate whether bradykinesia and mental slowness are present in patients with OCD.Methods:Participants comprised 19 non-depressed anti-psychotic free patients with OCD.Bradykinesia was assessed with the motor section of the Unified Parkinson's Disease Rating Scale (UPDRS). Mental slowness was investigated with the WAIS-R and the Y-BOCS. Psychiatric evaluation was performed with: SCID-I, Y-BOCS, HAMD, HAM-A, and MMPI. Cognitive functions were assessed with the WAIS-R.Results:Bradykinesia and mental slowness were present respectively in the 39% and 89% of the patients. Bradykinesia was positively correlated to Y-BOCS mental slowness score (rho=0.48, p< 0.05), and inversely related to the WAIS-R Performance IQ score (rho=-0.65, p< 0.01). Patients with bradykinesia scored significantly lower in the Similarities and Digit symbol coding WAIS-R subscales as compared to non-bradykinetic patients. in our sample pathological doubt was not associated with IQ measures nor with bradykinesia. Twelve out of 19 patients (63%) showed impairments in the nonverbal function scores.Conclusions:The novel findings of this study is that bradykinesia can be present in patients with OCD, and it is correlated with mental slowness and nonverbal performance impairment. These preliminary data support the notion that dysfunction of basal ganglia is possibly present in OCD patients.

Abstract
Background There are currently limited data for the use of specific antiviral therapies for the treatment of Ebola virus disease (EVD). While there is anecdotal evidence that supportive care may be effective, there is a paucity of direct experimental data to demonstrate a role for supportive care in EVD. We studied the impact of ICU-level supportive care interventions including fluid resuscitation, vasoactive medications, blood transfusion, hydrocortisone, and ventilator support on the pathophysiology of EVD in rhesus macaques infected with a universally lethal dose of Ebola virus strain Makona C07. Methods Four NHPs were infected with a universally lethal dose Ebola virus strain Makona, in accordance with the gold standard lethal Ebola NHP challenge model. Following infection, the following therapeutic interventions were employed: continuous bedside supportive care, ventilator support, judicious fluid resuscitation, vasoactive medications, blood transfusion, and hydrocortisone as needed to treat cardiovascular compromise. A range of physiological parameters were continuously monitored to gage any response to the interventions. Results All four NHPs developed EVD and demonstrated a similar clinical course. All animals reached a terminal endpoint, which occurred at an average time of 166.5 ± 14.8 h post-infection. Fluid administration may have temporarily blunted a rise in lactate, but the effect was short lived. Vasoactive medications resulted in short-lived improvements in mean arterial pressure. Blood transfusion and hydrocortisone did not appear to have a significant positive impact on the course of the disease. Conclusions The model employed for this study is reflective of an intramuscular infection in humans (e.g., needle stick) and is highly lethal to NHPs. Using this model, we found that the animals developed progressive severe organ dysfunction and profound shock preceding death. While the overall impact of supportive care on the observed pathophysiology was limited, we did observe some time-dependent positive responses. Since this model is highly lethal, it does not reflect the full spectrum of human EVD. Our findings support the need for continued development of animal models that replicate the spectrum of human disease as well as ongoing development of anti-Ebola therapies to complement supportive care.

Abstract
BACKGROUND To make surgical training more effective, a proven method is needed to provide feedback to residents on their surgeries. Residency programs may make up for limited training time in the operating room by improving feedback that trainees receive about cases. OBJECTIVE The goals of this study were (1) to determine if an online tool to communicate feedback for attendings and trainees shows face validity and (2) to use an online tool to identify the most common feedback trainees receive after performing orchiopexy and hypospadias repair by survey. METHODS In 2016, determining whether an online tool to provide pediatric urology trainees feedback after surgery shows face validity begun. The tool was launched at the authors' institutions. Then, attendings, fellows, and postgraduate year 4-5 trainees of 65 resident training programs were surveyed for their observations on preparing for and performing orchiopexy and hypospadias repair using the study tool to identify common feedback. RESULTS The results of using the tool to provide feedback shows face validity are as follows: feedback was exchanged between attendings and trainees on orchiopexy (n = 28) and hypospadias (n = 22). Anecdotally, the tool was easy to use. The results of using the tool to identify the most common feedback trainees receive by survey are as follows: from a pool of 65 institutions, 37 attendings and 28 trainees were enrolled who made 219 observations. Most trainees prepare using undocumented online resources (17/28, 67%) instead of speaking with their attendings or cotrainees (11/28, 33%). For orchiopexy, most respondents reported that trainees need to improve skills for hernia ligation (observations: attending = 28/45, 62%; and trainee = 17/26, 65%) and strategies for hernia exposure (observations: attending = 17/27, 62%; and trainee = 7/12, 58%). For hypospadias, most respondents reported that trainees need to improve skills for neourethroplasty (observations: attending = 31/53, 58%; and trainee = 10/16, 62%) and strategies for repair choice (observations: attending = 15/22, 68%; and trainee = 12/18, 67%) (chi-squared, all P = NS). DISCUSSION It was shown that both trainees and attendings agree on the areas of surgical strategy and execution which require improvement. With this study, it is also shown that the online feedback tool developed shows face validity in allowing attendings and trainees to communicate before and after surgery. CONCLUSIONS The most common feedback pediatric urology trainees receive for routine pediatric urology surgery is identified. Online tools that emphasize remediations to address a trainee's specific feedback needs are to be built, so that they will be able to improve their skills at their next case.

Abstract
OBJECTIVE The study aimed to explore premorbid academic and social functioning in patients with schizophrenia, and its associations with the severity of negative symptoms and neurocognitive impairment. METHOD Premorbid adjustment (PA) in patients with schizophrenia was compared to early adjustment in unaffected first-degree relatives and healthy controls. Its associations with psychopathology, cognition, and real-life functioning were investigated. The associations of PA with primary negative symptoms and their two factors were explored. RESULTS We found an impairment of academic and social PA in patients (P ≤ 0.000001) and an impairment of academic aspects of early adjustment in relatives (P ≤ 0.01). Patients with poor PA showed greater severity of negative symptoms (limited to avolition after excluding the effect of depression/parkinsonism), working memory, social cognition, and real-life functioning (P ≤ 0.01 to ≤0.000001). Worse academic and social PA were associated with greater severity of psychopathology, cognitive impairment, and real-life functioning impairment (P ≤ 0.000001). Regression analyses showed that worse PA in the academic domain was mainly associated to the impairment of working memory, whereas worse PA in the social domain to avolition (P ≤ 0.000001). CONCLUSION Our findings suggest that poor early adjustment may represent a marker of vulnerability to schizophrenia and highlight the need for preventive/early interventions based on psychosocial and/or cognitive programs.

Abstract
UNLABELLED This study deals with the role of texture analysis as a predictive factor of radiation-induced insufficiency fractures in patients undergoing pelvic radiation. INTRODUCTION This study aims to assess the texture analysis (TA) of computed tomography (CT) simulation scans as a predictive factor of insufficiency fractures (IFs) in patients with pelvic malignancies undergoing radiation therapy (RT). METHODS We performed an analysis of patients undergoing pelvic RT from January 2010 to December 2014, 24 of whom had developed pelvic bone IFs. We analyzed CT-simulation images using ImageJ macro software and selected two regions of interest (ROIs), which are L5 body and the femoral head. TA parameters included mean (m), standard deviation (SD), skewness (sk), kurtosis (k), entropy (e), and uniformity (u). The IFs patients were compared (1:2 ratio) with controlled patients who had not developed IFs and matched for sex, age, menopausal status, type of tumor, use of chemotherapy, and RT dose. A reliability test of intra- and inter-reader ROI TA reproducibility with the intra-class correlation coefficient (ICC) was performed. Univariate and multivariate analyses (logistic regression) were applied for TA parameters observed both in the IFs and the controlled groups. RESULTS Inter- and intra-reader ROI TA was highly reproducible (ICC > 0.90). Significant TA parameters on paired t test included L5 m (p = 0.001), SD (p = 0.002), k (p = 0.006), e (p = 0.004), and u (p = 0.015) and femoral head m (p < 0.001) and SD (p = 0.001), whereas on logistic regression analysis, L5 e (p = 0.003) and u (p = 0.010) and femoral head m (p = 0.027), SD (p = 0.015), and sex (p = 0.044). CONCLUSIONS In our experience, bone CT TA could be correlated to the risk of radiation-induced IFs. Studies on a large patient series and methodological refinements are warranted.

Abstract
BACKGROUND Functional decline among patients with mental illness is not unique to individuals with psychotic disorders. Despite this, research on early predictors of functional outcome mainly focused on individuals thought to have an 'at risk mental state' (ARMS) for psychosis. There is evidence suggesting that certain early vulnerability markers, such as neurological soft signs (NSS), may explain variability in functional outcomes independent of the level of psychosis risk and the traditional diagnostic classification. METHOD Structural equation modeling was applied to baseline data from a prospective longitudinal study of 138 young individuals in treatment with secondary services for non-psychotic disorders. We evaluated theoretically based models of pathways to functional outcome starting from NSS. The intervening variables were established according to previous evidence and drawn from two general categories: cognition (neuro- and social-) and negative symptoms (expressive and experiential). RESULTS A final trimmed model was a single path running from NSS to neurocognition to experiential negative symptoms to outcome. It could not be improved by adding or dropping connections that would change the single path to multiple paths. The indirect effect from NSS to outcome was significant. The validity of the model was independent of the ARMS status and the psychiatric diagnosis. CONCLUSIONS Our results provide evidence for a single pathway model in which the starting and intervening variables represent modifiable trans-diagnostic therapeutic targets to improve functional trajectories in young individuals with a recent-onset psychiatric diagnosis and different levels of psychosis risk.

Abstract
IntroductionShort stature caused by growth hormone (GH) deficiency is one of the causes of the “Failure to Thrive” (FTT) condition. In absence of clear organic causes, several different psychosocial conditions may play a role in explaining the FTT phenotype. Advances in developmental psychology have highlighted the role of emotions and caregiving behaviors in the organization of child's personality and psychobiology, with the mother–son attachment bond being considered a fundamental developmental experience. The objective of the present preliminary study was to assess whether there are significant correlations between attachment styles and GH levels in a sample of subjects with non-organic FTT.MethodsWe enrolled 27 children (mean age: 9.49 ± 2.63) with non-organic FTT. Perceived attachment security was assessed through the Security Scale (SS) and its subscales focused on maternal and paternal security. Pearson partial correlation was used to test associations between GH levels and SS measures adjusting for confounding factors (i.e. age, gender and BMI).ResultsAcross all subjects, GH was significantly positively correlated with general security (r = 0.425; P = 0.038) and maternal security (SSM) (r = –0.451; P = 0.027) and not significantly correlated with paternal security (SSP) (r = 0.237; P = 0.264).DiscussionThese findings preliminarily suggest that perceived attachment security may play a role in the etiopathogenesis of non-organic GH deficiencies and add to the accumulating evidence that attachment styles are associated with specific psychoendocrine underpinnings.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
BACKGROUND Accuracy of risk algorithms for psychosis prediction in "at risk mental state" (ARMS) samples may differ according to the recruitment setting. Standardized criteria used to detect ARMS individuals may lack specificity if the recruitment setting is a secondary mental health service. The authors tested a modified strategy to predict psychosis conversion in this setting by using a systematic selection of trait-markers of the psychosis prodrome in a sample with a heterogeneous ARMS status. METHODS 138 non-psychotic outpatients (aged 17-31) were consecutively recruited in secondary mental health services and followed-up for up to 3 years (mean follow-up time, 2.2 years; SD=0.9). Baseline ARMS status, clinical, demographic, cognitive, and neurological soft signs measures were collected. Cox regression was used to derive a risk index. RESULTS 48% individuals met ARMS criteria (ARMS-Positive, ARMS+). Conversion rate to psychosis was 21% for the overall sample, 34% for ARMS+, and 9% for ARMS-Negative (ARMS-). The final predictor model with a positive predictive validity of 80% consisted of four variables: Disorder of Thought Content, visuospatial/constructional deficits, sensory-integration, and theory-of-mind abnormalities. Removing Disorder of Thought Content from the model only slightly modified the predictive accuracy (-6.2%), but increased the sensitivity (+9.5%). CONCLUSIONS These results suggest that in a secondary mental health setting the use of trait-markers of the psychosis prodrome may predict psychosis conversion with great accuracy despite the heterogeneity of the ARMS status. The use of the proposed predictive algorithm may enable a selective recruitment, potentially reducing duration of untreated psychosis and improving prognostic outcomes.

Abstract
The strong comorbidity between metabolic diseases and severe psychiatric disorders, although object of extensive scientific literature in recent years, is still a challenge for researchers, in order to clarify the pathogenic mechanisms that underlie this relationship, and for clinicians, in order to optimize strategies for prevention and early interventions. Particular attention is linked to insulin resistance, which can represent a primum movens able to adversely affect the course of the dysmetabolic and psychiatric frameworks. Through extensive review of the scientific literature on PubMed, we analyze the latest scientific findings about the bidirectional nature of this comorbidity. Our aim is also to identify an instrument applicable on a large scale in psychiatric populations, able to quickly recognize the insulin resistance. In particular, the HOMA (Homeostasis Model Assessment) index for its features of high specificity, sensitivity, low-cost and easy execution of the method, can be a useful tool, predictive and diagnostic at the same time, which can significantly improve the quality of life and the course of disease for these patients.

Abstract
INTRODUCTION Many studies aimed at validating the application of Dual Energy Computed Tomography (DECT) in clinical practice where conventional CT is not exhaustive. An example is given by bone marrow oedema detection, in which DECT based on water/calcium (W/Ca) decomposition was applied. In this paper a new DECT approach, based on water/cortical bone (W/CB) decomposition, was investigated. MATERIALS AND METHODS Eight patients suffering from marrow oedema were scanned with MRI and DECT. Two-materials density decomposition was performed in ROIs corresponding to normal bone marrow and oedema. These regions were drawn on DECT images using MRI informations. Both W/Ca and W/CB were considered as material basis. Scatter plots of W/Ca and W/CB concentrations were made for each ROI in order to evaluate if oedema could be distinguished from normal bone marrow. Thresholds were defined on the scatter plots in order to produce DECT images where oedema regions were highlighted through color maps. The agreement between these images and MR was scored by two expert radiologists. RESULTS For all the patients, the best scores were obtained using W/CB density decomposition. CONCLUSIONS In all cases, DECT color map images based on W/CB decomposition showed better agreement with MR in bone marrow oedema identification with respect to W/Ca decomposition. This result encourages further studies in order to evaluate if DECT based on W/CB decomposition could be an alternative technique to MR, which would be important when short scanning duration is relevant, as in the case of aged or traumatic patients.

Abstract
OBJECTIVE There is considerable uncertainty about whether depression screening programs in primary care may improve outcomes and what specific features of such programs may contribute to success. We tested the effectiveness of a program involving substantial commitment from local mental health services. METHODS Prospective, randomised, patient- and evaluator-masked, parallel-group, controlled study. Participants were recruited in several urban primary care practices where they completed the PC-SAD screener and WHOQOL-Bref. Those who screened positive and did not report suicidal ideation (N=115) were randomised to an intervention group (communication of the result and offer of psychiatric evaluation and treatment free of charge; N=56) or a control group (no feedback on test result for 3 months; N=59). After 3 months, 100 patients agreed to a follow-up telephone interview including the administration of the PC-SAD5 and WHOQOL-Bref. RESULTS Depression severity and quality of life improved significantly in both groups. Intent-to-treat analysis showed no effect of the intervention. As only 37% of patients randomised to the intervention group actually contacted the study outpatient clinic, we performed a per-protocol analysis to determine whether the intervention, if delivered as planned, had been effective. This analysis revealed a significant positive effect of the intervention on severity of depressive symptoms, and on response and remission rate. Complier average causal effect analysis yielded similar results. CONCLUSION Due to the relatively small sample size, our findings should be regarded as preliminary and have limited generalizability. They suggest that there are considerable barriers on the part of many patients to the implementation of depression screening programs in primary care. While such programs can be effective, they should be designed based on the understanding of patients' perspectives.

Abstract
IntroductionA high proportion of individuals with eating disorders (EDs) report childhood abuse and neglect. The prevalence of traumatic events in ED patients has been extensively investigated; less is known about their self-perceived–and reported–severity. Objectives/Aims: We aimed to assess in ED patients vs. healthy controls the severity, i.e., duration, perpetrator, and subjective impact, of sexual, physical, and emotional traumas suffered from 0 to 18 years, paying particular attention to emotional neglect.MethodsFifty-seven consecutive DSM-V ED patients (91.2% females; age range: 18–42 years) were recruited at the Psychiatric Outpatient Clinic of our University Hospital. Ninety controls (78.9% females; age range: 20–39 years) were also recruited. Among ED patients, 43.9% had restrictive anorexia nervosa (AN), 29.8% binge/purging AN, 26.3% bulimia nervosa. Individuals completed the Eating Disorder Inventory-2 (EDI-2) and the Traumatic Experiences Checklist (TEC).ResultsThe severity of all traumatic events, according to the TEC total score, was significantly higher in ED patients than controls (P < 0.001). Moreover, ED patients showed significantly higher scores with regard to emotional neglect (P < 0.001) and emotional abuse (P < 0.001). The same can be said for physical traumas (P < 0.01) and physical abuse (P < 0.01), although with a lower significance, and for sexual abuse (P < 0.05), with an even lower significance. No difference in the severity of sexual harassment was found.ConclusionsAll types of traumas, especially neglect, can occur in ED patients and controls, however they are reported as more severe by ED patients.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionIndividuals with eating disorders (EDs) often report a history of early traumatization. Although a great attention has been paid to sexual and physical trauma, less is known about emotional one, especially neglect.Objectives/aimsWe aimed to estimate the prevalence of sexual, physical, and emotional trauma–occurring under 18 years of age–in ED patients vs. healthy controls, focusing on emotional abuse and neglect.MethodsWe consecutively recruited 57 DSM-V ED outpatients (91.2% females; age range = 18–42 years) at the Psychiatric Outpatient Clinic of our University Hospital and 90 healthy controls (78.9% females; age range = 20–39 years). Among ED patients, 43.9% had restrictive anorexia nervosa (AN), 29.8% binge/purging AN, 26.3% bulimia nervosa. Individuals completed the Eating Disorder Inventory-2 (EDI-2) and the Traumatic Experiences Checklist (TEC). We used Mann-Whitney U test and χ2 test for comparisons.ResultsED patients scored significantly higher than controls on all EDI-2 subscales (P-values < 0.05). On the TEC, emotional trauma was more frequent than sexual/physical ones in both ED patients and controls. Emotional trauma, and to a lesser extent physical one, were significantly more frequent in ED patients than controls. Distinguishing between emotional abuse and neglect, the latter had a higher prevalence than the former in both groups. Additionally, ED patients reported significantly more neglect, but not emotional abuse, than controls.ConclusionsOur findings show a high prevalence of emotional trauma in EDs, mainly neglect, i.e., a lack of care and attention potentially contributing to EDs. Thus, it is crucial to investigate emotional neglect in ED patients.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
We report on the engineering of a nondispersive (flat) energy band in a geometrically frustrated lattice of micropillar optical cavities. By taking advantage of the non-Hermitian nature of our system, we achieve bosonic condensation of exciton polaritons into the flat band. Because of the infinite effective mass in such a band, the condensate is highly sensitive to disorder and fragments into localized modes reflecting the elementary eigenstates produced by geometric frustration. This realization offers a novel approach to studying coherent phases of light and matter under the controlled interplay of frustration, interactions, and dissipation.

Abstract
Etiology of depressive disorders is still unknown. Several factors are involved in its pathophysiology such as neurotransmitters and neuroendocrine alterations, genetics, life events and their appraisal. Some of these components are strictly linked. Subjects with a family member affected by mood disorders are more prone to suffer from depressive disorders. It is also true that receiving feedbacks of indifference or neglect during childhood from one parent who suffer from depression may represent a factor of vulnerability. Indeed, reaction to a specific negative event may determine an increased allostasis which lead to a depressive episode. Thus, a psychological cause does not exclude a neurobiological cascade. Whereas in other cases recurrent depressive episodes appear in absence of any negative life event. This review provides a set of data regarding the current etiopathogenesis models of depression, with a particular attention to the neurobiological correlates and vulnerability factors.

Abstract
OBJECTIVE The cingulate cortex is a functionally heterogeneous region involved in diverse cognitive and emotional processes. It is a region of special interest to investigate the neurological substrate of schizophrenia. The aim of this paper is to review all the studies that investigated the relation between the cingulate cortex and two of the most important and little known areas of this disease: the psychotic onset and the negative symptoms. MATERIAL AND METHODS Relevant literature was identified through a search in PubMed, Web of Science, and Cochrane database. Search terms included negative symptoms, cingulate cortex, cingulate gyrus, schizophrenia, PET, SPECT, MRI, fMRI, BOLD, deficit schizophrenia, early-onset schizophrenia, psychotic onset, psychosis. RESULTS 9 studies evidenced a link between negative symptoms and hypoactivity of cingulate cortex, whereas 7 studies did not. A positive relationship between anterior cingulate cortex gray matter thinning and high risk for schizophrenia is well characterized in literature. CONCLUSIONS In a large portion of patients hypoactivity of cingulate cortex underlie the presence of negative symptoms. In particular, ACC (anterior cingulated cortex) thinning seems to be related to the increasing social withdrawal that is characteristic of the psychosis prodrome. New therapies focused on the brain stimulation of the cingulate cortex could represent an important aid for patients with this kind of symptoms.

Abstract
In PTSD, sleep disorders represent an important symptoms dimension which is associated with more severe PTSD and increased risk of relapse. The basic treatment for PTSD is not always associated to an improvement of sleep disturbances and nightmares. Alpha-blockers, and more specifically Prazosin, have shown a specific action on sleep disorders in PTSD. We report the clinical case of a young women with PTSD, who was suffering from severe sleep disorder and distressing nightmare. The patient was treated with Terazosin, a conger of Prazosin, and has shown symptom remission. Further studies on the use of alpha-blokers might reveal new therapeutic options in PTSD.

Abstract
In the last decades, the potential association between antidepressants and cancer risk has been increasingly investigated. Fundamental researches, performed on animal models and cell tumoral lines, have highlighted several biological mechanisms possibly supporting this association. Nevertheless, the epidemiological studies investigating the risk of cancer in patients receiving selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs) have provided conflicting and inconclusive results. Therefore, the prescription of several antidepressants in oncologic patients still remains a matter of discussion. The aim of this review is to present and discuss available evidence concerning the association between the risk of breast and prostate cancer and the use of antidepressant medications. Thus, consistencies, differences, and contradictions of available data are reported. A special focus is addressed to amisulpiride, a widely prescribed drug still poorly investigated with regard to the risk of cancer occurrence and recurrence. Overall, there is no definitive evidence of increased risk of breast and prostate cancer among patients exposed to SSRIs and TCAs. The association between amisulpiride and cancer risk has been to date scarcely explored and considered in clinical settings. Nevertheless, the hyperprolactinemia frequently resulting from its adoption has been repeatedly associated, to increased cancer risk and poorer prognosis in cancer patients. Thus, the use of amisulpiride among cancer patients should be carefully considered.

Abstract
Background: Depression goes often unrecognised and untreated in non-psychiatric medical settings. Screening has recently gained acceptance as a first step towards improving depression recognition and management. The Primary Care Screener for Affective Disorders (PC-SAD) is a self-administered questionnaire to screen for Major Depressive Disorder (MDD) and Dysthymic Disorder (Dys) which has a sophisticated scoring algorithm that confers several advantages. This study tested its performance against a ‘gold standard’ diagnostic interview in primary care. Methods: A total of 416 adults attending 13 urban general internal medicine primary care practices completed the PC-SAD. Of 409 who returned a valid PC-SAD, all those scoring positive (N=151) and a random sample (N=106) of those scoring negative were selected for a 3-month telephone follow-up assessment including the administration of the Structured Clinical Interview for DSM-IV-TR Axis I Disorders (SCID-I) by a psychiatrist who was masked to PC-SAD results. Results: Most selected patients (N=212) took part in the follow-up assessment. After adjustment for partial verification bias the sensitivity, specificity, positive and negative predictive value for MDD were 90%, 83%, 51%, and 98%. For Dys, the corresponding figures were 78%, 79%, 8%, and 88%. Conclusions: While some study limitations suggest caution in interpreting our results, this study corroborated the diagnostic validity of the PC-SAD, although the low PPV may limit its usefulness with regard to Dys. Given its good psychometric properties and the short average administration time, the PC-SAD might be the screening instrument of choice in settings where the technology for computer automated scoring is available.

Abstract
Deep transcranial magnetic stimulation (TMS) is a technique of neuromodulation and neurostimulation based on the principle of electromagnetic induction of an electric field in the brain. The coil (H-coil) used in deep TMS is able to modulate cortical excitability up to a maximum depth of 6 cm and is therefore able not only to modulate the activity of the cerebral cortex but also the activity of deeper neural circuits. Deep TMS is largely used for the treatment of drug-resistant major depressive disorder (MDD) and is being tested to treat a very wide range of neurological, psychiatric and medical conditions. The aim of this review is to illustrate the biophysical principles of deep TMS, to explain the pathophysiological basis for its utilization in each psychiatric disorder (major depression, autism, bipolar depression, auditory hallucinations, negative symptoms of schizophrenia), to summarize the results presented thus far in the international scientific literature regarding the use of deep TMS in psychiatry, its side effects and its effects on cognitive functions.

Abstract
BACKGROUND The prevalence of depressive disorders is high among patients with skin disease. The PC-SAD is a 37-item self-administered depression screening questionnaire that has been validated in dermatological patients. OBJECTIVE The aim of this study was to develop and validate a brief depression severity instrument derived from the PC-SAD that can be used to assess severity and monitor ongoing clinical course. METHODS Two patient samples participated in the study: 72 adult dermatological inpatients and 73 adults attending six primary care practices. Psychiatric assessment included the Structured Clinical Interview for DSM-IV and an 18-item version of the PC-SAD; moreover, dermatological patients completed the Patient Health Questionnaire depression scale (PHQ-9), while primary care patients were administered the Montgomery-Asberg Depression Rating Scale (MADRS). A subset of five PC-SAD items showing the best psychometric properties were selected, and the reliability and validity of the resulting instrument (PC-SAD5) were examined. RESULTS The PC-SAD5 showed satisfactory internal consistency in both samples. There was a high correlation between PC-SAD5 and PHQ-9 and MADRS scores. Multiple regression analysis revealed a gradient of PC-SAD5 scores from patients with no mental disorder, those with milder forms of depression, to those with Major Depressive Disorder. Similar results were observed for the 18-item version of the PC-SAD. CONCLUSION The availability of valid and reliable continuous measures of depression severity derived from the PC-SAD extends its field of application from depression screening to use as a follow-up measure of depression severity in routine clinical practice. A validated very short instrument such as the PC-SAD5 may have substantial clinical value.
