Abstract I identify a point-symmetric structure in recently published VLT/MUSE velocity maps of different elements in a plane along the line of sight at the center of the supernova remnant SNR~0540-69.3, and argue that jittering jets that exploded this core collapse supernova shaped this point-symmetric structure. The four pairs of two opposite clumps that compose this point symmetric structure suggest that two to four pairs of jittering jets shaped the inner ejecta in this plane. In addition, intensity images of several spectral lines reveal a faint strip (the main jet-axis) that is part of this plane of jittering jets and its similarity to morphological features in a few other SNRs and in some planetary nebulae further suggests shaping by jets. My interpretation implies that in addition to instabilities, jets also mix elements in the ejecta of core collapse supernovae. Based on the point-symmetric structure and under the assumption that jittering jets exploded this supernova, I estimate the component of the neutron star natal kick velocity on the plane of the sky to be $\simeq 235 \km\s^{-1}$, and at an angle of $\simeq 47^\circ$ to the direction of the main jet-axis. I analyse this natal kick direction together with other 12 SNRs in the frame of the jittering jets explosion mechanism.

The importance of psychological factors in functional gastrointestinal disorders (FGID) is well-stablished in the literature; however, cognitive factors have hardly been researched and, in particular, cognitive conflicts have not been explored for these disorders. The aim of this study is to compare the cognitive and symptomatic characteristics of a group of 66 FGID patients (33 diagnosed with irritable bowel syndrome and 33 with functional dyspepsia) with a control group of participants without FGID or psychopathological symptoms. Both groups were matched by sex and age. The evaluation of the clinical sample was carried out following the criteria of the DSM-IV-TR. The SCL 90-R, and also the Repertory Grid for the identification of cognitive conflicts (implicative dilemmas) and self-ideal discrepancy, were administered to both the clinical sample and the control group. Results showed that 85% of FGID patients met the criteria for one axis I disorder of the DSM-IV-TR, mainly anxiety and somatization disorders. Regarding axis II, 23% presented at least one personality disorder, the most common ones being those of avoidance and dependence. Regarding axis IV, the patients reported a higher number of problems relative to the primary support group. FGID patients showed greater symptoms compared to the control group on various SCL 90-R scales. On the other hand, FGID patients presented more implicative dilemmas than healthy controls, as well as lower self-esteem. No significant differences were observed depending on the type of FGID (irritable bowel syndrome or functional dyspepsia).

Objective. Anxiety and depression have a negative influence in the quality of life. The aim of the study was to determinate the levels of sensitivity and specificity of the Anxiety and Hospital Depression Scale (HADS) and compare the quality of life in patients with inflammatory bowel disease (IBD) and depression or anxiety. Methods. This study included 104 patients with diagnosis of IBD. Each patient received psychiatric intervention with SCID-I (Structured Clinical Interview for DSMIV Axis I Disorders) instrument as a gold standard to stablish the cut-off points of HADS. Quality of life was also evaluated with IBDQ-32. Demographic and clinical variables were collected. Results. Most of the patients reported a high quality of life (73.1%, n = 76 ), while 25.0% ( n = 26 ) express a moderate quality of life. The ROC curves for both psychiatric entities showed an adequate discriminative capacity of the HADS-anxiety dimension ( AUC = 0.84 , 95 % CI = 0.76 -0.92) with a limited discriminability of the HADS-depression dimension ( AUC = 0.58 , 95 % CI = 0.46 -0.70) using the proposed scoring of 8 as a cut-off point. Conclusions. Anxiety and depression impact negatively in the quality of life in Mexican patients with IBD. The Mexican version of HADS had acceptable internal consistency and external validity, with moderate sensitivity and specificity for clearly identifying clinical cases of anxiety and depression in patients with IBD.

Background: The prevalence of mental disorders is an important topic, which has been reported in different countries in the world. In China, some studies were also conducted to get the prevalence of mental disorders at the national level and in some metropolitan cities. However, the prevalence of mental disorders in Chinese underdeveloped provinces has not been reported internationally in recent decades. Due to the discrepancy in the social-economic development of different Chinese provinces, we also have reasons to believe the different prevalence of mental disorders between underdeveloped provinces and other provinces.Method: A community-based cross-sectional study was conducted among community residents aged 18 years and older in Hebei province, China. We screened 20,884 community residents in this study, and a Structured Clinical Interview for Diagnostic and Statistical Manual (DSM-IV) Axis I disorders was used to make the diagnoses of mental disorders.Results: The weighted lifetime prevalence of mental disorders was 15.87% (95% CI 15.38–16.38%), and the 1-month prevalence was 10.79% (95% CI 10.37–11.22%). Anxiety disorder ranked first in the classification of mental disorders for both lifetime (6.56%) and 1-month prevalence (6.25%). The weighted lifetime and 1-month region–gender–age-specific prevalence of mental disorders was also analyzed in this study.Conclusions: Mental disorders have been an important issue in Chinese economically underdeveloped regions, and the prevalence was at a high level compared with the results in the 2000s. There are several serious challenges in the work of Chinese mental disorders, which should be paid more attention to.

Abstract Background The magnitude of the problem of substance use in Egypt has been growing lately. Substance use disorders have been associated with depression and suicide, as well as impulsivity and specific personality traits. Suicide is closely linked to the substances use. Therefore it is very important to confirm the factors that affect the possibility of suicide. Aim of the Work This study aimed at evaluating suicide risk and its correlation with each of personality disorders and severity of addiction in a sample of 72 tramadol addicts from outpatient clinic of Institute of psychaitry Ain Shams University hospitals. Patients and Methods This is a descriptive Cross sectional study conducted in outpatient clinic of Institute of psychaitry Ain Shams University hospital. The present study aimed at analyzing the demographic data of 72 tramadol addicts, over six months period from January 2018 to August 2019. The severity of the addiction problem among those patients was assessed using Addiction Severity Index (ASI), suicidal probability was assessed using suicide probability scale (SPS), Structured Clinical Interview for DSM-VI Axis II (SCID-II) for assessing personality disorders and Structured Clinical Interview for DSM-IV Axis I Disorders (SCID I). Results The results showed that 32 (44.44%) of the patients had a risk of suicide probability. Also there was a statistically significant difference between risk of suicidal probability and personality disorders especially antisocial personality. It was found that the need for more power for work and pleasurable effects were the most risk factors for tramadol addiction. Conclusion Suicide probability was found to be (44.44%) among the studied tramadol addicts. The risk of suicide probability among them was found to be significant in each of the following: antisocial personality disorder, longer duration of addiction, being single and positive family history of addiction. Attention should be paid to include the assessment of suicidal risk as part of routine assessment of addicts.

Background: Medically unexplained physical symptoms (MUPS) are highly prevalent, frequently co-occurring with psychiatric symptoms such as depression, alexithymia, and anxiety. Objective: To evaluate the relation between depression, anxiety, and alexithymia and severity of somatic symptoms in patients with MUPS. Method: This is a cross-sectional study conducted on 196 patients suffering from MUPS. The patients were recruited from tertiary care internal medicine and neuropsychiatry clinics during the first quarter of 2019. The Patient Health Questionnaire (PHQ-15), (PHQ-9), Generalized Anxiety Disorder (GAD-7), Structured Clinical Interview for DSM-IV Axis I Disorders Clinician Version (SCID-I-CV), and Toronto Alexithymia Scale (TAS-20) were employed to assess somatic severity, depression, anxiety, major mental disorders, and alexithymia in the sample of patients. Results: The results of the study indicate that GAD-7 and PHQ-9 scores had a positive correlation with PHQ-15 ( p < 0.05) in multivariate regression. In contrast, TAS-20 was not independently correlated with PHQ-15. Adding TAS-20 to GAD-7 and PHQ-9 in the equation of the regression model enhances the predictive capacity of the model ( p < 001). Conclusion: The results of the study indicate that only anxiety and depressive symptoms, but not alexithymia, were associated independently with MUPS severity.

The co-occurrence of psychiatric disorders in people with epilepsy (PWE) is not well documented or studied. Anxiety and depressive disorders are the most frequent comorbid disorders in PWE. In this paper, we characterized the rates of multiple psychiatric disorder comorbidity by reanalyzing data from a study sample of PWE. A total of 96 outpatient PWE completed the self-report symptom scale, and were diagnosed using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) Axis I disorders (SCID-I). For analyses, patients were assigned to a comprehensive diagnostic group of anxiety and depressive disorders. In order to determine comorbidity across psychiatric diagnoses for the DSM-IV categories, Pearson’s chi-squared test (χ2) was used. In the study sample, eight patients (8.3% of the study sample, n = 96) had comorbid major depressive disorder and anxiety disorder. When looking at comorbidity of each diagnosis separately, it was determined that 50% of individuals with an anxiety disorder had comorbid Major Depressive Disorder (MDD) and 38% patients with MDD had comorbid anxiety disorder. This finding encourages a more systematic reporting of psychiatric prevalence data in epilepsy, especially taking into account the high ratio of multiple comorbid anxiety and depressive disorders in PWE.

Abstract Background To assess whether magnetic resonance imaging (MRI) findings of condylar erosion (CE) are predictive of a specific clinical diagnosis of painful closed lock of the temporomandibular joint (TMJ), and to determine the strength of association between CE and types of internal derangement (ID). Methods Based upon sample size estimation, this retrospective paired-design study involved 62 patients, aged between 18 and 67 years. Inclusion criteria were the presence of a unilateral clinical diagnosis of arthralgia coexisting with disk displacement without reduction (‘AR and DDwoR/wLO’), assigned according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis I, and the absence of signs and symptoms of TMJ pain and dysfunction on the contralateral TMJ side. Bilateral sagittal and coronal MR images were obtained to establish the prevalence of CE and TMJ ID types of disk displacement with (DDR) and without reduction (DDNR). Logistic regression analysis was used to compute odds ratios for CE and ID types. Confounding variables adjusted for were age, sex, time since pain onset, pain intensity, and type of ID. Results In the regression analysis, the MRI items of DDR (p = 0.533) and DDNR (p = 0.204) dropped out as nonsignificant in the diagnostic clinical ‘AR and DDwoR/wLO’ group. Significant increases in the risk of ‘AR and DDwoR’ occurred with CE (3.1:1 odds ratio; p = 0.026). The presence of CE was significantly related to DDNR (adjusted OR = 43.9; p <  0.001). Conclusions The data suggest CE as a dominant factor in the definition of painful closed lock of the TMJ, support the view that joint locking needs to be considered as a frequent symptom of osteoarthritis, and emphasize a strong association between the MRI items of CE and DDNR.
