Evidence for a Variable Ultrafast Outflow in the Newly Discovered Ultraluminous Pulsar NGC 300 ULX-1

Ultraluminous pulsars are a definite proof that persistent super-Eddington accretion occurs in nature. They support the scenario according to which most Ultraluminous X-ray Sources (ULXs) are super-Eddington accretors of stellar mass rather than sub-Eddington intermediate mass black holes. An important prediction of theories of supercritical accretion is the existence of powerful outflows of moderately ionized gas at mildly relativistic speeds. In practice, the spectral resolution of X-ray gratings such as RGS onboard XMM-Newton is required to resolve their observational signatures in ULXs. Using RGS, outflows have been discovered in the spectra of 3 ULXs (none of which are currently known to be pulsars). Most recently, the fourth ultraluminous pulsar was discovered in NGC 300. Here we report detection of an ultrafast outflow (UFO) in the X-ray spectrum of the object, with a significance of more than 3{\sigma}, during one of the two simultaneous observations of the source by XMM-Newton and NuSTAR in December 2016. The outflow has a projected velocity of 65000 km/s (0.22c) and a high ionisation factor with a log value of 3.9. This is the first direct evidence for a UFO in a neutron star ULX and also the first time that this its evidence in a ULX spectrum is seen in both soft and hard X-ray data simultaneously. We find no evidence of the UFO during the other observation of the object, which could be explained by either clumpy nature of the absorber or a slight change in our viewing angle of the accretion flow.Comment: 10 pages, 4 figures.

DYSPHORIA AS A PSYCHIATRIC SYNDROME: A PRELIMINARY STUDY FOR A NEW TRANSNOSOGRAPHIC DIMENSIONAL APPROACH

Background: We currently define dysphoria as a complex and disorganized emotional state with proteiform phenomenology, characterized by a multitude of symptoms. Among them prevail irritability, discontent, interpersonal resentment and surrender. Dysphoria, in line with the most recent Interpersonal Dysphoria Model, could represent a “psychopathological organizer” of the Borderline Personality Disorder. We would like to extend this theoretical concept to other psychiatric disorders in order to consider dysphoria as a possible psychopathological nucleus, a syndrome on its own. This syndromic vision may open up the possibility of new paths both in the differential diagnosis and in the therapeutic approach to the various disorders. Aims: The goal of this paper is to understand if the dimensional spectrum that composes dysphoria differs from the different psychiatric disorders. Specifically, we would like to assess if the phenomenological expression of dysphoria differs in patients with Borderline Personality Disorder (BPD), Mixed State Bipolar Disorder (BDM) and Major Depressive Disorder (MDD) through an observational comparative study. Subjects and methods: In this study, 30 adult patients, males and females between the ages of 18 and 65, were enrolled from the Psychiatric Service of the Santa Maria della Misericordia Hospital in Perugia (PG), Italy, from January 1st to June 30th, 2018. The aim was to form 3 groups each one composed of 10 individuals affected respectively with Borderline Personality Disorder (BPD), with Bipolar Disorder, Mixed State (BPM) and Major Depression Disorder (MDD). After a preliminary assessment to exclude organic and psychiatric comorbidity, we administered them the Neapen Dysphoria Scale – Italian Version (NDS-I), a specific dimensional test for dysphoria. Starting from the dataset, with the aid of the statistical program SPSS 20, we have obtained graphs showing the comparison between disorders groups selected and NDS-I total score and subscales (irritability, discontent, interpersonal resentment, surrender). Finally, a comparison was made, taking two groups at a time, between the means of single groups for total scores and for single subscales considered into the NDS-I test. We made it using the Mann-Whitney U test, a nonparametric test with 2 independent samples, by setting a significance level =0.05. Conclusions: This study, through a transnosographic-dimensional approach, allowed us to explore dysphoria and its expressions in different psychopathological groups, despite analyzing a small sample. Differences between means of values obtained through NDS-I subscales were statistically significant in patients with BPD, BDM and MDD (p<0.05). Among the latter, the group of BPD patients has greater pervasiveness and severity of dysphoria symptoms

DYSPHORIA DIMENSIONS: A PRELIMINARY INPATIENTS STUDY TO DIFFRENTIATE BORDERLINE PERSONALITY AND BIPOLAR DISORDER SPECTRUM

Background: Differentiating Borderline Personality Disorder (BPD) from Bipolar Disorder (BD) represents a very difficult challenge for clinicians. Dysphoria could be a possible key to differentiate these disorders. We currently define dysphoria as a complex and disorganized emotional state with proteiform phenomenology, characterized by a multitude of symptoms. Among them irritability, discontent, interpersonal resentment and surrender prevail. These dimensions can be detected using the Neapen Dysphoria Scale - Italian version (NDS-I). Dysphoria role in BPD has been highlighted by the recent theorization of the Interpersonal Dysphoria Model, according to which dysphoria could represent the “psychopathological organizer” of the BPD. On the other side, dysphoria role in BD has not yet been established. This is simply considered as an aspect, and not fundamental, of the symptomatology characterizing BD, especially in mixed states patients. The phenomenological analysis of the dimensional spectrum of dysphoria within BPD and DB could provide a valuable aid in the differential diagnosis between BPD and BD. Aims: The aim of this paper is to verify if the dimensional spectrum of dysphoria differs between Borderline Personality Disorder (BPD) and Bipolar Disorder Spectrum (BD) through an observational comparative study Subjects and methods: In this study, 65 adult patients, males and females between the ages of 18 and 65, were enrolled from the Psychiatric Service of the Santa Maria della Misericordia Hospital in Perugia (PG), Italy, from January 1st 2018 to April 30th 2019. We have formed 2 groups. A BPD group composed of 33 patients (19 female patients, representing approximately 57.6 % of the sample) and a BD group composed of 32 patients (18 Female patients, representing approximately 56.2% of the sample). Patient’s comorbid with BD and BPD have been excluded from the study. After a preliminary assessment to exclude organic and psychiatric comorbidity, and after at least 72 hours from hospitalization, we administered them the Neapen Dysphoria Scale - Italian Version (NDS-I), a specific dimensional test for dysphoria. Starting from the dataset, with the aid of the statistical program SPSS 20, we have carried out a comparison between disorders groups selected and their NDS-I total score and subscales (irritability, discontent, interpersonal resentment, surrender); For this we have used the Mann-Whitney U test, a nonparametric test with 2 independent samples, by setting a significance level p<0.05. Conclusions: This study allowed us to explore and analyze dysphoria dimensions expressions in BPD and BD. Despite the small sample analyzed, the results show a significant different dimensional spectrum expression of the dysphoria between the two disorders. In particular, Irritability and Interpersonal Resentment dimensions show greater interest in BPD than BD spectrum. Further studies with a larger and stratified sample are needed to confirm these results

A DUAL THERAPEUTIC SETTING MODEL EXPERIENCE FOR SCHIZOTYPAL PERSONALITY DISORDER IN AN INPATIENT UNIT

G.B., 21-year-old patient of Albanian origin suffering from acute psychotic burning on schizotypal personality disorder induced by substance abuse, was admitted to the Psychiatric Service at Perugia’ General Hospital, Italy. On admission, antipsychotic therapy was set up which had the role to reduced delusional and hallucinatory symptoms but the suspiciousness, the presence of magical thought and the closure towards surrounding world that characterize it, combined with the presence of intrusive images, consequently increased the anxiety experiences and negatively affects the establishment of a therapeutic relationship with the operators. During the hospitalization, daily support interviews were carried out: G.B. showed clear difficulty in expressing his own thought contents in presence of more than two operators emerged jointly with the tendency to project different emotional experiences based on the gender of the operator. Following these observations, with the aim to carrying out an intervention that could integrate a psychological approach to the pharmacological therapy in place, a specific personalized support setting was set up, consisting of a female and a male operator. This setting was structured coherently with the therapeutic goals to be achieved: creation of a therapeutic alliance, the integration of the patient\u27s emotional experiences and containing the splitting through the transference analysis. By means of this setting, the patient has obtained a substantial improvement of the splitting framework allowing a better integration of his emotional experiences. At the end of the sessions, G.B. showed more confidence with the medical staff and showed himself to be more aware of his pathological and non-pathological mental states and consequently more adherent to taking drug therapy and to the continuation of post-discharge psychological therapy

CANNABINOID-INDUCED PSYCHOSIS: A CROSS-SECTIONAL GENDER STUDY

Background: Gender is a crucial factor in the development of mental illnesses, with an essential influence on clinical characteristics and not only on the prevalence of each disorder. Gender differences in cannabinoid-related disorders are highlighted by different research fields (preclinical, clinical, socio-demographic studies), but few studies focused on differential symptom expression in cannabinoid-induced psychosis. This study aims at investigating qualitative and quantitative gender differences in specific psychopathological domains in a clinical sample of subjects affected by cannabinoid-induced psychotic disorder, without psychiatric comorbidity. Subjects and methods: The study was carried out at the Psychiatric Inpatient Service of General Hospital of Perugia (Italy). In this cross-sectional gender study, 28 inpatients were enrolled, 14 males (M) and 14 females (F). Participants were administered a psychometric battery consisting of 7 tests (PANSS, NDS-I, YMRS, HAM-D, HAM-A, AQ, SSI) in order to investigate 7 psychopathological domains (Psychosis, Dysphoria, Mania, Depression, Anxiety, Aggressive Behaviour and Suicide Ideation). Scores obtained at each test were compared between male and females by using Mann-Whitney U test (p<0.05). Results: In this study, we observed that males present higher severity of psychotic symptoms, with prominent scores in PANSS positive and general psychopathology scale (p<0.001), and an important expression of aggressive behavior (p<0.001) compared with females. Female sample, instead, shows a greater expression of dysphoria and depressive domains (p<0.001) and a lower, but statistically significant, prevalence in the anxiety domains expression (p=0.01). By these observations, we could assert that in male group thought disorders are prominent. On the other hand, in female group affective disorder are prominent. Conclusions: This study confirmed how gender influences the phenomenic expression of psychiatric disorders. In line with the precision medicine paradigm, a further clarification of different clinical profiles based on gender would allow the choice of a personalized treatment plan with better efficacy and accuracy indices
