RESUMEN

Non-suicidal self-injury (NSSI) is an issue primarily of concern in adolescents and young adults. Recent literature suggests that persistent, repetitive, and uncontrollable NSSI can be conceptualized as a behavioral addiction. The study aimed to examine the prevalence of NSSI with addictive features and the association of this prevalence with demographic and clinical variables using a cross-sectional and case-control design. A total of 548 outpatients (12 to 22 years old) meeting the criteria for NSSI disorder of DSM-5 were enrolled and completed clinical interviews by 4 psychiatrists. NSSI with addictive features were determined by using a single-factor structure of addictive features items in the Ottawa self-injury inventory (OSI). Current suicidality, psychiatric diagnosis, the OSI, the revised Chinese Internet Addiction Scale, the Childhood Trauma Questionnaire, and the 20-item Toronto Alexithymia Scale were collected. Binary logistic regression analyses were used to explore associations between risk factors and NSSI with addictive features. This study was conducted from April 2021 to May 2022. The mean age of participants was 15.93 (SD = 2.56) years with 418 females (76.3%), and the prevalence of addictive NSSI was 57.5% (n = 315). Subjects with addictive NSSI had a higher lifetime prevalence of nicotine and alcohol use, a higher prevalence of current internet addiction, suicidality, and alexithymia, and were more likely to have physical abuse/neglect, emotional abuse, and sexual abuse than NSSI subjects without addictive features. Among participants with NSSI, the strongest predictors of addictive features of NSSI were female (OR = 2.405, 95% CI 1.512-3.824, p < 0.0001), alcohol use (OR = 2.179, 95% CI 1.378-3.446, p = 0.001), current suicidality (OR = 3.790, 95% CI 2.351-6.109, p < 0.0001), and psysical abuse in childhood (OR = 2.470, 95% CI 1.653-3.690, p < 0.0001). Nearly 3 out of 5 patients (12-22 years old) with NSSI met the criteria of NSSI with addictive features in this psychiatric outpatients sample. Our study demonstrated the importance of the necessity to regularly assess suicide risk, and alcohol use, as well as focus more on females and subjects who had physical abuse in childhood to prevent addictive NSSI.

RESUMEN

BACKGROUND AND OBJECTIVES: Non-suicidal self-injury (NSSI) behavior is one of the characteristics of borderline personality disorder (BPD) in adolescents. Prior studies have shown that adolescents with BPD may have a unique pattern of brain alterations. The purpose of this study was to investigate the alterations in brain structure and function including gray matter volume and resting-state functional connectivity in adolescents with BPD, and to assess the association between NSSI behavior and brain changes on neuroimaging in adolescents with BPD. METHODS: 53 adolescents with BPD aged 12-17 years and 39 age-gender matched healthy controls (HCs) were enrolled into this study. Brain magnetic resonance imaging (MRI) was acquired with both 3D-T1 weighted structural imaging and resting-state functional imaging. Voxel-based morphometry (VBM) analysis for gray matter volume and seed-based functional connectivity (FC) analysis were performed for assessing gray matter volume and FC. Clinical assessment for NSSI, mood, and depression was also obtained. Correlative analysis of gray matter alterations with self-injury or mood scales were performed. RESULTS: There were reductions of gray matter volume in the limbic-cortical circuit and default mode network in adolescents with BPD as compared to HCs (FWE P < 0.05, cluster size ≥ 1000). The diminished gray matter volumes in the left putamen and left middle occipital gyrus were negatively correlated with NSSI in adolescents with BPD (r = - 0.277 and P = 0.045, r = - 0.422 and P = 0.002, respectively). Furthermore, there were alterations of FC in these two regions with diminished gray matter volumes (voxel P < 0.001, cluster P < 0.05, FWE corrected). CONCLUSIONS: Our results suggest that diminished gray matter volume of the limbic-cortical circuit and default mode network may be an important neural correlate in adolescent BPD. In addition, the reduced gray matter volume and the altered functional connectivity may be associated with NSSI behavior in adolescents with BPD.

RESUMEN

The neurobiological mechanism of borderline personality disorder (BPD) in adolescents remains unclear. The study aimed to assess the alterations in neural activity within prefrontal cortex in adolescents with BPD and investigate the relationship of prefrontal activity with emotional regulation and cognitive function. This study enrolled 50 adolescents aged 12-17 years with BPD and 21 gender and age-matched healthy control (HC) participants. Study assessment for each participant included a brain resting-state functional MRI (rs-fMRI), clinical assessment questionnaires such as Borderline Personality Features Scale (BPFS), Difficulties in Emotion Regulation Scale (DERS), Ottawa Self-Injury Inventory and Childhood Trauma Questionnaire (CTQ) and cognitive testing with Stroop Color-Word Test (SCWT). Fractional amplitude of low-frequency fluctuations (fALFF) and seed-based functional connectivity (FC) were obtained from rs-fMRI analysis. Correlation analysis was also performed to evaluate the associations of the neuroimaging metrics such as fALFF and FC with clinical assessment questionnaire and cognitive testing scores. Adolescents with BPD showed increased fALFF values in the right inferior frontal gyrus and decreased activity in the left middle frontal gyrus as compared to the HC group (p < 0.05, cluster size ≥ 100, FWE correction). In adolescents with BPD, increased fALFF in the right inferior frontal gyrus was related to the BPFS (emotional dysregulation), DERS-F (lacking of emotional regulation strategies) and Ottawa Self-Injury Inventory-4 C scores (internal emotional regulation function of self-injurious behavior). The reduced fALFF in the left middle frontal gyrus was associated with the SCWT-A (reading characters) and the SCWT-B (reading color) scores. Additionally, the fALFF values in the left middle frontal gyrus and the right inferior frontal gyrus were related to the CTQ-D (emotional neglect) (p < 0.05). The left middle frontal gyrus exhibited increased FC with the right hippocampus, left inferior temporal gyrus and right inferior frontal gyrus (voxel p < 0.001, cluster p < 0.05, FWE correction). The increased FC between the left middle frontal gyrus and the right hippocampus was related to the SCWT-C (cognitive flexibility) score. We observed diverging changes in intrinsic brain activity in prefrontal cortex, and neural compensatory changes to maintain function in adolescents with BPD. In addition, decreased neural function was closely associated with emotional dysregulation, while increased neural function as indicated by brain activity and FC was associated with cognitive dysfunction. These results indicated that alterations of intrinsic brain activity may be one of the underlying neurobiological markers for clinical symptoms in adolescents with BPD.

RESUMEN

BACKGROUND: Adolescents with borderline personality disorder often have cognitive impairment, but the underlying mechanism for this is not clear. This study was aimed at assessing alterations in regional homogeneity using resting-state functional MRI (fMRI) in adolescents with borderline personality disorder, and evaluating the associations between regional homogeneity and cognitive testing scores. METHODS: We enrolled 50 adolescents with borderline personality disorder (age 12-17 years) and 21 age- and sex-matched healthy controls. We performed regional homogeneity and seed-based functional connectivity analysis for both groups. We also performed correlative analysis for regional homogeneity and cognitive testing scores. RESULTS: Compared with healthy controls, adolescents with borderline personality disorder had reduced regional homogeneity values in the frontal cortex (including the left inferior orbitofrontal cortex and the bilateral superior frontal cortex) as well as in the left precuneus in the default mode network. Adolescents with borderline personality disorder also had higher regional homogeneity values in several cortical regions: the right middle temporal gyrus, the right cuneus, the right precentral gyrus and the left middle occipital gyrus. Regional homogeneity values in the left middle occipital gyrus, left inferior orbitofrontal cortex and right superior frontal gyrus were associated with cognitive testing scores in adolescents with borderline personality disorder. We also found increased functional connectivity between the left middle occipital gyrus and right superior frontal gyrus in adolescents with borderline personality disorder. LIMITATIONS: This study had a modest sample size, with a possible case selection bias for patients with more severe illness. This cohort also included patients with comorbidities or taking psychotropic medications, which may have confounded study results. CONCLUSION: Alterations in regional homogeneity and functional connectivity in brain regions that involve the limbic-cortical circuit could be neural correlates for cognitive impairment in adolescents with borderline personality disorder.

RESUMEN

Adolescents with borderline personality disorder (BPD) may have impaired executive functions. There are few functional MRI (fMRI) studies in adolescents with BPD and the neuroimaging markers of this disorder are unknown. The aim of this study was to investigate the functional connectivity (FC) of BPD in adolescents, and to explore the relationship between FC changes and executive function in adolescents with BPD. 50 adolescents aged 12 to 17 years with BPD and 21 gender-and-age matched healthy controls (HC) were enrolled into the study. Brain MRI scan including a 3D-T1 weighted structural sequence and a resting-state fMRI was acquired. A seed-based FC analysis was performed. We used the Stroop color-word test (SCWT) and the trail making test (TMT) to evaluate the executive function of the participants. Correlative analysis of FC alterations with executive function and clinical symptoms was also performed. Compared to the HCs, adolescents with BPD showed increased FC in the limbic-cortical circuit, such as the FC between the left hippocampus and right parahippocampal gyrus, between the right middle occipital gyrus and the left middle temporal gyrus, and between the left medial superior frontal gyrus and the right inferior temporal gyrus. FC in the default mode network (DMN) was decreased between the left angular gyrus and the left precuneus but increased between the left angular gyrus and the right anterior cingulate cortex (voxel P < 0.001, cluster P < 0.05, FWE corrected). The BPD group demonstrated significantly lower cognitive testing scores than the HC group on the SCWT-A (P < 0.001), SCWT-B (P < 0.001), and SCWT-C (P = 0.034). The FC alterations between limbic system and cortical regions were associated with SCWT and TMT (P < 0.05). FC alterations were noted in both limbic-cortical circuit and DMN in adolescents with BPD, which were associated with impaired executive function. This study implicated the FC alterations as the neural correlates of executive functioning in adolescents with BPD.

RESUMEN

OBJECTIVES: To understand the psychological status of the staff in a general hospital during the coronavirus disease 2019 and its influential factors, and to provide references for the mental health services to hospital staff. METHODS: Using star platform of questionnaire, the staff in the general hospital were investigated via Depression, Anxiety, Stress Scale (DASS-21), Social Support Rating Scale (SSRS) and Simplified Coping Style Questionnaire (SCSQ). The influential factors were discussed by descriptive analysis, rank sum test, single factor analysis, correlation analysis and multiple factors binary logistic regression analysis. RESULTS: A total of 2 060 valid questionnaires were collected. The negative emotions of nurses and cleaners were the most obvious. The depression scores, anxiety scores and stress scores for nurses and cleaners were 5.06±7.47, 6.36±7.84, 9.75±8.65, and 6.72±8.84, 4.51±6.56, 9.69±9.56, respectively. Multivariate binary logistic regression analysis showed that staff types, education levels, job status, economic situation and concerns on the supplies of protective goods were the main influential factors for depression; staff types, contacting status with infected patients, economic situation, concerns on the supplies of protective goods, history of disease were the main influential factors for anxiety; contacting status with infected patients, economic situation, concerns on the supplies of protective goods were the main influential factors for stress. CONCLUSIONS: There are differences in psychological characteristics among different groups of staff in the general hospital under the outbreak. Thus psychological protection and intervention measures should be formulated according to different groups and work status.

RESUMEN

OBJECTIVE: To explore the rates of suicide ideation and the relevant factors among patients with HIV/AIDS (PLWHA) in Changsha for obtaining scientific evidence to reduce suicidal ideation rates among PLWHA.
 Methods: A total of 504 PLWHA were surveyed in an AIDS hospital in Changsha, by using Self-Made Socio-Demographic Scale, Self-rating Depression Scale, Self-rating Anxiety Scale, and Beck Scale for Suicide Ideation-Chinese Version.
 Results: There were 13.9%, 26.6% and 27.2% of PLWHA suffered suicidal ideation in the last week, at the most depressive moments and all their lives, respectively. Being a gay (OR=4.79, 2.66, 2.37) or with suicide history (OR=8.56, 5.63, 5.56) were the risk factors for suffering suicidal ideation in the last week, at the most depressive moments and all their lives. Moreover, anxiety was the risk factor for suffering suicidal ideation at the most depressive moments and all their lives (OR=3.28, 3.05), and depression was the risk factor for suffering suicidal ideation in the last week (OR=4.97).
 Conclusion: Among PLWHA, gay is a high risk factor for suffering suicidal ideation, and suicide history is a risk factor.

RESUMEN

BACKGROUND: Research has shown the diagnostic potential of optical coherence tomography (OCT) and OCT angiography (OCTA) in various psychiatric disorders. However, there is few research focusing on changes specific to Major Depressive Disorder (MDD), and the diagnostic value of OCT combined with OCTA parameters for MDD remains unclear. METHODS: In this study, we investigated microvascular and morphology changes in the retina of MDD patients using a combination of OCTA and OCT parameters, and to examine their correlation with MDD mood and cognitive function in order to assess their diagnostic capability. RESULTS: Our findings revealed a significant decline in macular vessel density (MVD) in the superficial retinal capillary plexus (SRCP) across all subfields, except the NO area. We also observed a significant positive correlation between fovea and Stroop-1, as well as between temporal inner (TI) and Stroop-3 in MDD patients. Furthermore, we identified a negative correlation between fovea and Self-Rating Depression Scale, as well as between Superior outer (SO) and Difficulties in Emotion Regulation Scale-C in MDD patients. LIMITATIONS: The sample size was small. Anatomical variables in blood flow may contribute to variability between subjects and outcomes. CONCLUSIONS: The diagnostic value of OCTA suggests their potential as valuable tools for monitoring and diagnosing MDD.

RESUMEN

BACKGROUND: Major depressive disorders (MDD) and bipolar disorders (BD) are the most common psychiatric diagnoses of suicide attempts (SA) in adolescents. However, little is known regarding the differences in incidence and clinical-related features of SA between these two disorders. The study aims to examine the SA incidence and related factors in adolescents with MDD versus BD. METHOD: A retrospective survey was conducted in outpatients. SA incidence, demographic characteristics and substance use history were collected. Symptom Checklist-90 was used to measure the severity of symptoms. The Revised Chinese internet addiction scale and Barratt Impulsiveness Scale-11 were utilized to assess the presence of internet addiction and impulsiveness. The Childhood Trauma Questionnaire was used to measure childhood maltreatment subtypes. RESULTS: 295 MDD and 205 BD adolescents were recruited. The incidence of SA for MDD and BD were 52.5 % and 56.4 %, respectively. BD adolescents who attempted suicide showed worse symptoms, higher rates of nicotine and alcohol use, higher motor and non-planning impulsivity, and a more childhood physical abuse proportion than MDD adolescents with SA. Physical abuse in childhood was found to be associated with SA in both disorders (OR = 1.998 for MDD; OR = 2.275 for BD), while higher anxiety (OR = 1.705), and alcohol use (OR = 2.094) were only associated with SA in MDD. LIMITATIONS: Retrospective, cross-sectional design cannot draw causality, and biases in self-report measurements cannot be ignored. CONCLUSIONS: The findings revealed some difference between BD and MDD for adolescents with SA, and it emphasize significance of prompt identification and exact distinction between BD and MDD in adolescents.

RESUMEN

BACKGROUND: Non-suicidal self-injurious behavior (NSSI) is the core characteristic of adolescent borderline personality disorder (BPD) and visual working memory is involved in the pathological processes of BPD. This study aimed to investigate alterations in white matter microstructure and their association with NSSI and visual working memory in adolescents with BPD. METHODS: 53 adolescents diagnosed with BPD and 39 healthy controls (HCs) were enrolled. White matter microstructure was assessed with the fractional anisotropy (FA) and mean diffusivity (MD) from diffusion tensor imaging (DTI). Correlation analysis was performed to assess the association between FA/MD and core features of BPD. A mediation analysis was performed to test whether the effects of white matter alterations on NSSI could be mediated by visual working memory. RESULTS: Adolescents with BPD showed a reduced FA and an increased MD in the cortical-limbic and cortical-thalamus circuit when compared to the HCs (p < 0.05). Increased MD was positively correlated with NSSI, impulse control and identity disturbance (p < 0.05), and was negatively correlated with the score of visual reproduction. Reserved visual working memory masked the effects of white matter microstructural alterations on NSSI behavior. CONCLUSIONS: White matter microstructural deficits in the cortical-limbic and cortical-thalamus circuits may be associated with NSSI and visual working memory in adolescents with BPD. Reserved visual working memory may protect against NSSI.

RESUMEN

BACKGROUND: Childhood trauma may cause borderline personality disorder (BPD). The aim of this study was to assess functional alteration and its association with childhood trauma in Chinese adolescents with BPD. METHODS: A total of 187 adolescents with BPD aged 12-17 years and 207 age and gender- matched healthy controls (HCs) were enrolled into this study. The sample consisted of 50 adolescents with BPD and 21 HCs underwent brain resting-state functional magnetic resonance imaging (rs-fMRI). The rs-fMRI data was analyzed for both neural activity as indicated by amplitude of low-frequency fluctuation (ALFF) and seed-based functional connectivity (FC). Clinical assessment for childhood trauma, impulsivity, and depression was also performed. Correlative analysis of functional alterations with childhood trauma assessment were performed. RESULTS: Adolescents with BPD had significantly higher rate of all assessed childhood trauma than the HC group (P < 0.001). Most adolescents with BPD (61.5 %) had emotional neglect, which was the most commonly seen type of childhood trauma. Compared with HCs, adolescents with BPD showed decreased ALFF in the cortical regions including the left superior frontal gyrus and right middle occipital gyrus, and default mode network (DMN) regions including the left angular gyrus and medial superior frontal gyrus. Adolescents with BPD also showed enhanced ALFF in the limbic system (left hippocampus, insula, thalamus) (P < 0.05, FWE correction, cluster size ≥100). There were significant correlations between the insula ALFF and childhood trauma assessment for emotional neglect, physical abuse and physical neglect (P < 0.01). Moreover, adolescents with BPD showed increased FC between the left insula and right cortical regions (voxel P < 0.001, cluster P < 0.05, FWE correction). LIMITATIONS: The sample size was small. This cohort had patients with more severe BPD symptoms and some had comorbidities such as anxiety and obsessive-compulsive disorder. CONCLUSIONS: There were alterations of brain activity as indicated by ALFF in the limbic - cortical circuit and DMN regions in adolescents with BPD and the activity in the left insula was correlated with emotional neglect. In addition, the FC between the left insula and the limbic - prefrontal circuit was enhanced. These results implicate that the functional alterations of insula may serve as a potential neuroimaging biomarker for adolescents with BPD who suffered from childhood trauma.

RESUMEN

BACKGROUND: Accurate early diagnosis of adolescent borderline personality disorder (BPD) is critical for prompt treatment. The aim of this study was to assess the alteration of brain surface morphology and to evaluate its relationship with core features in adolescent BPD. METHODS: A total of 52 adolescents with BPD aged 12-17 years and 39 age- and sex-matched healthy controls (HCs) were prospectively enrolled into the study. Brain magnetic resonance imaging (MRI) was obtained with both 3D-T1 weighted structural sequence and resting-state functional data. The structural data was analyzed for surface morphology parameters including the local gyrification index (LGI), mean curvature and surface area. The functional MRI data was analyzed for seed-based functional connectivity (FC). Correlative analysis of surface morphology and core features of adolescent BPD was performed. RESULTS: Adolescents with BPD showed the following altered surface morphology in the limbic-cortical circuit when compared to the HCs: (1) reduced LGI in the left fusiform and right superior temporal gyrus; (2) reduced mean curvature in the left precentral gyrus and right rostral anterior cingulate cortex, and increased mean curvature in the bilateral pericalcarine; and (3) reduced surface area in the left paracentral gyrus, left pars triangularis, right insula and right lateral orbitofrontal gyrus (P < 0.05, FWE correction). In addition, these brain regions with altered surface morphology were significantly correlated with several core features including the mood instability, self-identity problems, and non-suicidal self-injury behavior in adolescents with BPD (P < 0.05). Furthermore, there was enhanced functional connectivity among these altered brain regions within the limbic-cortical circuit (voxel P < 0.001, cluster P < 0.05, FWE corrected). CONCLUSIONS: Adolescents with BPD had significant alterations of brain surface morphology in the limbic-cortical circuit, which was correlated with core BPD features. These results implicated the surface morphology parameters and FC alterations may potentially serve as neuroimaging biomarkers for adolescents with BPD.

RESUMEN

Background: The aim of this study was to describe the sleep quality and its influencing factors among medical workers of different working statuses and staff types during the coronavirus disease 2019 (COVID-19) epidemic. Methods: Through an online questionnaire survey, all medical staffs in Xiangya Hospital were invited to complete sections on general information, the Self-Rating Scale of Sleep (SRSS), the Depression, Anxiety and Stress Scale (DASS-21), the Social Support Rating Scale (SSRS), and the Simplified Coping Style Questionnaire (CSQ). Results: A total of 4,245 respondents completed the survey. Among them, 38.7% had sleep disturbance. After matching, the SRSS scores in the staffs who were assigned to the intensive care unit (ICU) of Union Hospital in Wuhan and working in the epidemic area of Xiangya Hospital were not significantly different (P > 0.05); the SRSS scores in the battlefront staffs were significantly higher than (P < 0.05) those who were not treating patients infected with COVID-19. The SRSS scores of nurses were significantly higher than those of doctors and hospital administrators (P < 0.01). Anxiety, depression, and coping style were associated with sleep disturbance. Conclusion: The sleep quality of the medical staffs has been impaired during the epidemic period, especially among nurses, doctors, and administrators who are working on the front line. Medical institutions should strengthen psychological services and coping strategies for medical staffs.

RESUMEN

INTRODUCTION: People living with HIV/AIDS (PLWHA) have a higher rate of suicide compared to the general population. Psychosocial factors closely correlate with suicidal ideation and it is essential to explain the relationships between related factors among PLWHA. OBJECTIVES: To establish a structural equation model and examine direct and indirect effects of social support, coping strategy, depression symptoms and suicidal ideation among PLWHA. PATIENTS AND METHODS: A total of 504 PLWHA completed a set of questionnaires in the HIV clinic of Changsha Infectious Disease Hospital between December 2015 and January 2016. RESULTS: Among the 504 respondents, a total of 27.2% (n=137) had experienced suicidal ideation in their lifetime. The goodness of fit for the two structural equations model was highly satisfactory. Depression symptoms had a significant direct impact on suicidal ideation (ß 1=0.401, ß 2=0.422), while problem-focused coping (ß=-0.067), emotion-focused coping (ß=-0.081) and social support (ß=-0.137) had a significant indirect effect with suicidal ideation via depression symptoms. Factors of total effects were ranked from large to small as follows: depression, social support, emotion-focused coping and problem-focused coping. CONCLUSION: Findings provide more understanding of direct and indirect associations between variables, suggesting that depression screening services, and the strengthening of social support and psychological care services among PLWHA can potentially prevent suicide.
