Psycho-Socio-Demographic Risk Factors of Self-injurious Behaviors in Iranian Females Inmates: A Case-Control Study

Background: Self-injurious behavior or self-harm among inmates is a common phenomenon. However, no study has yet been conducted in Iran regarding self-harm in female inmates. Objectives: The present study aimed to investigate the psycho-socio-demographic risk factors associated with non-suicidal self-harm in Iranian female inmates. Patients and Methods: Participants in this case-control study were 306 female inmates in Tehran, who were randomly selected and divided into two groups: (1) 88 individuals who scored 5 or higher on the Sansone Self-harm Inventory (SHI), and (2) 88 individuals randomly selected from the 218 inmates who did not self-harm as the comparison group. The participants completed a researcher-designed questionnaire, SHI, and the Difficulties in Emotion Regulation Scale. The data were analyzed using logistic regression analysis in SPSS version 16. Results: Logistic regression analysis revealed that marital status (B = 1.438, P = 0.002), arrest history (B = 1.295, P = 0.005), substance abuse (B = 1.198, P = 0.011), psychiatric diagnoses (B = 1.126, P = 0.018), parental divorce (B = 1.280, P = 0.005), and difficulties in emotion regulation (B = 0.027, P = 0.022) were significant predictors of self-harm in inmates. Although there was a difference in the addiction rates of parents between those with self-harm and those without, this variable did not predict self-harm in female inmates (B = 0.488, P = 0.307). Conclusions: The results of this study underscore the importance of family-based preventive interventions to prevent self-harm behaviors among female inmates.

Rare but Relevant: Characterizing Self-Inflicted Burn Injuries in the United States.

Self-inflicted burns (SIBs) represent a distinct entity in burn care often associated with an underlying psychiatric etiology. In this review, we summarize the existing evidence on SIBs in North America to inform targeted prevention and interventions for patients afflicted with SIBs. The following databases were queried to identify relevant articles used for literature review: PubMed, Embase, and Scopus. The main outcome measures were burn characteristics and risk factors of SIBs in the American population. A total of 14,189 patients were included across 13 included studies. The percent of total body surface area burned ranged from less than one to 100%, with a mean of 29.6 +/- 20.7%. Depressive disorders were the most reported overall; however, among mood disorders, bipolar disorder was also reported frequently, while anxiety was reported least. Motives for self-inflicting burn injury included premeditated self-injury as a coping mechanism, escape or response to delusions, impulsive self-injury, and most commonly, suicidal intention. The majority of the studies reported that pre-admission drug and alcohol abuse were associated with the occurrence of SIBs. Other identified risk factors for SIB injury included female sex, younger age, unemployment, and unmarried status. From this, it is imperative that targeted interventions are developed to address the complex interplay of psychiatric disorders, drug use, and other demographic risk factors among the American population. It is crucial for initiatives to emphasize early identification of individuals at-risk of self-harm, better access to mental health services, and stronger drug abuse programs to target SIB occurrence in the U.S..

Mobile phone addiction and self-injury in adolescents with MDD: mediation by self-esteem and depression, and the failure of usage restrictions

BackgroundPrevious studies have suggested a significant association between mobile phone addiction (MPA) and non-suicidal self-injury (NSSI) in general adolescents. However, limited research has analyzed this relationship in clinical populations, such as those with major depressive disorder (MDD), and the potential mediation mechanisms remain unclear.MethodsThis cross-sectional observational study analyzed data from 2343 adolescents with MDD (77.9% females; mean age = 14.99 years, SD = 1.65). Using mediation models, we explored the roles of self-esteem and depression severity (measured by Patient Health Questionnaire-9) in the relationship between MPA and NSSI. Additionally, we evaluated the associations between existing school-implemented mobile phone usage policies and levels of MPA, self-esteem, depression symptoms, and NSSI.ResultsMPA was significantly associated with NSSI, with low self-esteem and increased depression severity almost entirely mediating this effect (log-odds = 0.016, 95%CI = 0.02–0.013). Subdomains of MPA, including inability to control craving, feelings of anxiety, and productivity loss, followed similar mediation models, while the subdomain of withdrawal/escape had a partial effect mediated by depression severity. Additionally, enforced restrictions on mobile phone usage in schools did not show positive effects on related variables and even exacerbated MPA by increasing cravings and reducing productivity.ConclusionOur study suggests that MPA in adolescents with MDD may be an important risk factor for NSSI occurrence, and that reducing the negative impact of mobile phone usage on self-esteem and depressive symptoms, rather than simply restricting usage, may be crucial for effective intervention.

Mediating effects of child schema mode in the relationship between negative parent-child relationships in childhood and non-suicidal self-injurious behavior in college students

This study was aimed to investigate the psychological mechanisms underlying non-suicidal self-injurious behavior. For this purpose, we hypothesized that dysfunctional child modes act as a psychological mechanism to influence the relationship between negative parent-child relationships in childhood and current cognitions (catastrophizing), emotions (emotional dysregulation and depression), and behaviors (non-suicidal self-injurious behaviors). A sample of 430 college students (male 97, female 333) with experience of non-suicidal self-injurious behavior was selected to test the multi-mediation effects of child schema mode (angry, impulsive), catastrophizing, emotional dysregulation, and depression on the relationship between negative parent-child relationships in childhood and non-suicidal self-injury. As a result of structural equation modeling analysis, it was found that negative parent-child relationships in childhood directly influenced child schema mode, catastrophizing, depression, and non-suicidal self-injurious behaviors. In addition, it was found that negative parent-child relationships in childhood were dually mediated by child schema mode and depression and child schema mode and emotional dysregulation. The present study highlights the mediating role of child schema modes as a psychological mechanism underlying the relationship between negative parent-child relationships in childhood and non-suicidal self-injurious behavior. Based on these findings, the usefulness and direction of schema therapy interventions in the field of non-suicidal self-injury counseling are discussed.

Epidemiology and characteristics of unintentional self-inflicted penetrating ocular injuries in children less than 6 years-old

IntroductionPediatric ocular injuries, notably unintentional self-inflicted penetrating ocular injuries in children under 6, pose a substantial public health concern, leading to visual impairment and psychological distress. With global prevalence indicating severe visual impairment or blindness in 2–14% of affected children, these injuries necessitate multiple surgeries and extended monitoring. Our study aims to analyze the epidemiology and characteristics of such injuries, emphasizing preventive measures, parental supervision, and timely medical intervention to mitigate their impact on young lives.MethodConducted at Khalili Hospital in Shiraz, Iran, our retrospective study included 141 cases admitted between April 2018 and April 2023. Ethical principles guided data collection from medical records, encompassing demographic details, causative objects, ocular laceration specifics, surgical procedures, complications, and visual acuity assessments.ResultsThe mean age of the participants in this study was 47.18 ± 16.48 months (ranging from 10 to 71 months), and the male to female ratio was 1.76:1 (90 vs. 51). Objects of injury mostly included knives (34.8%), wood (12.1%), and glass (10.6%), and the most common initial manifestation of injury was iris prolapse (56.7%), followed by traumatic cataract (46.8%) and limbus laceration (34.0%). Fifteen (10.6%) patients had a visual acuity better than LogMAR 0.5, 24 (17.1%) had finger count vision, 37 (26.2%) had hand motion, 7 (0.5%) had light perception, and 58 (41.1%) were uncooperative. Type of laceration and season of injury were associated with retinal detachment, and a longer time-to-visit was correlated with a higher risk of developing retinal detachment or endophthalmitis.ConclusionOur study highlights the significant burden of unintentional self-inflicted penetrating ocular injuries in children under 6. Emphasizing preventive measures, parental supervision, and timely medical intervention, our findings underscore the potential psychological and visual consequences. This research advocates for parental education and safety measures to reduce the occurrence and severity of such injuries in this vulnerable population, promoting a healthier and safer environment for children.

Risk of Suicide and Suicidality in Patients with Moderate to Severe Psoriasis: results from the British Association of Dermatologists Biologic and Immunomodulators Register (BADBIR).

Psoriasis is associated with poor mental health and reduced quality of life. Although the high risk for depression in patients with psoriasis is well-established, their suicidality risk is uncertain. Previous studies provide contrasting results and have not included patients with clinically-confirmed severe disease. Our aim was to determine risk of suicide among patients with moderate to severe psoriasis compared with the general population, and investigate if psychiatric comorbidity or history of suicidality increases future suicidality risk in psoriasis. We further estimated the incidence of suicidal and self-injurious behaviours in patients. Analysis was performed using the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR). As controls, general population mortality and suicide data were used. There were 9 suicides in BADBIR. The incidence rate of suicide was 12.5 per 100,000 person-years (95% CI 6.53, 24.11) in BADBIR versus 11.0 per 100,000 person-years (95% CI 10.7, 11.3) in the general population in England and Wales. Among patients, psychiatric comorbidity or past suicidality was associated with higher risk for suicidal ideation, suicide attempts and self-injurious behaviours. Suicide rates among patients with moderate to severe psoriasis were not significantly higher compared with the general population. Suicide is a rare event and our results are limited by the uncertainty in the estimate reliability. However, considering the high depression prevalence in psoriasis, our findings support the need for prompt assessment of patients for psychiatric comorbidities and suicidality history. Further research is required on suicidal behaviours and the role of psoriasis severity.

Programmatic and Organizational Barriers and Facilitators to Addressing High-Risk Issues in Supportive Housing and Housing First Programs.

Risk management is an important component of service delivery in supportive housing and Housing First programs. However, there is no evidence on the implementation of risk management approaches in these settings. This qualitative study examined what service providers working in supportive housing and Housing First programs in Canada identify as the programmatic and organizational factors that affect the prevention and management of high-risk behaviours and challenges (e.g., overdose, suicide attempts, non-suicidal self-injury, falls and fall-related injuries, fire-setting, hoarding, apartment takeovers, violence, property damage, drug selling) in their programs. In-depth interviews were completed with a purposive sample of 32 service providers. Data were analyzed using an integrative approach that incorporated techniques from qualitative description and thematic analysis. Four thematic factors, which were comprised of various barriers and facilitators, that affected management of high-risk issues in supportive housing and Housing First programs were identified: [1] flexibility in addressing risk issues; [2] early identification of risk issues; [3] built environment and housing location; and [4] resource availability. Overall, the findings underscore how service providers aim to identify high-risk issues promptly, beginning as early as referral, and that their capacity to effectively do this and intervene accordingly is dynamically shaped by various aspects of the program model, environment, and availability of internal and external resources. Yet, the findings also highlight how risk management approaches may conflict with other programmatic goals and values, and the importance of considering these collectively. Systems-level changes to strengthen programs' capacity to prevent risk and implications for future research are discussed.

Effects of decision making and impulsivity on the addictive features of non-suicidal self-injury behaviors in adolescents with depressive disorder

BackgroundNon-suicidal self-injury (NSSI) behaviors pose a significant threat to the physical and psychological well-being of adolescents. Recent research suggests that persistent, uncontrollable and repetitive NSSI can be conceptualized as a behavioral addiction. The addictive feature of NSSI behavior can be assessed using Ottawa self-injury inventory (OSI), the higher addiction score indicates the more serious NSSI behavior. This study aims to explore the relationship of impulsivity and decision-making on the addictive features of NSSI in adolescents with depressive disorder, to explore the influencing factors of behavioral addictive features of NSSI and to predict the addictive features of NSSI.MethodsUsing a cross-sectional design, a total of 126 adolescent outpatients and inpatients with a mean age of 15.49 years old (M = 15.49, SD = 1.56), male students (n = 28, 22.2%) and female students (n = 98, 77.8%) diagnosed with depressive disorders were recruited according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), and clinical interviews were completed by two psychiatrists. NSSI addictive features according to the OSI’s addictive features items. The final group was categorized into three groups: depression without NSSI (n = 42), depression with NSSI without addictive features (n = 44), and depression with NSSI and addictive features (n = 40). The present study employed the Hamilton Depression Scale (HAMD-24), Chinese Revised Barratt Impulsiveness Scale Version 11 (BIS-11), OSI, and the Adolescent Non-Suicidal Self-Injury Questionnaire (ANSSIQ). Cognitive decision-making abilities were assessed using the Iowa Gambling Task (IGT).ResultsThe depression with NSSI addictive features group had significantly lower total net scores and net scores of block3, block4, and block5 in the IGT than the depression without NSSI group, whereas there was no statistically significant difference between the two in net scores of block1 and block2. Lower scores mean more unfavorable decisions and strategy adjustments. The addictive features of NSSI behaviors were significantly and positively correlated with the severity of NSSI behaviors, depression, and cognitive impulsiveness, and significantly and negatively correlated with the total net score of the IGT. The severity of NSSI behaviors, severity of depression, cognitive impulsiveness positively predicts the addictive features of NSSI behaviors, the total net score of the IGT negatively predicted the addictive features of NSSI behaviors.ConclusionAdolescents with depressive disorders with NSSI behavioral addictive features had higher severity of depression, exhibited higher cognitive impulsivity, and made more unfavorable decisions when making choices.

Association Between Opioid Receptor Kappa 1 Gene Polymorphism, Kappa Opioid Receptor Level and Dynorphin Level with Non-Suicidal Self-Injury

Internet Search Activity for Intentional Self-Harm Forums After a High-Profile News Publication: Interrupted Time Series Analysis.

Searches for "pro-suicide" websites in the United States peaked during the week a high-profile news story was published and remained elevated for 6 months afterward, highlighting the need to avoid mentioning specific sources of explicit suicide instructions in media publications.

Sertraline medications plus dialectical behavior therapy for depressed adolescents with nonsuicidal self-injury behaviors.

The study aims to investigate the efficacy of sertraline medication plus dialectical behavior therapy (DBT) in reducing nonsuicidal self-injury (NSSI) behavior and depression among adolescents. Participants were 100 adolescents with depression and NSSI behaviors, 50 of whom received sertraline medication plus DBT and 50 of whom received sertraline medication plus cognitive behavioral therapy (CBT) for 12 weeks. During 6 months post intervention, 26 (57.8%) participants did not report having engaged in any form of NSSI in the sertraline + DBT group and 15 (32.6%) in the sertraline + CBT group, showing significant difference. The sertraline + DBT group and the sertraline + CBT group exhibited significant difference regarding the proportions of cutting skin and biting self. The scores of anxiety, depression, aggression against self in four modified overt aggression scale categories, and Personal and Social Performance were notably lower in the sertraline + DBT group than those in the sertraline + CBT group at 6 months post intervention. Sertraline medication plus DBT could decrease NSSI episodes and improve symptoms of anxiety and depression for adolescents, and these changes were comparable to those of CBT. More importantly, DBT was demonstrated better clinical improvements at 6-month follow-up.

How Is Rejection Sensitivity Linked to Non-Suicidal Self-Injury? Exploring Social Anxiety and Regulatory Emotional Self-Efficacy as Explanatory Processes in a Longitudinal Study of Chinese Adolescents.

Early adolescents are at high risk for non-suicidal self-injurious behavior (NSSI). Based on the Rejection Sensitivity Model, the Experiential Avoidance Model, and the Affect Regulation Model of Self-Injury, this study aimed to explain how rejection sensitivity was related to NSSI among adolescents by unraveling the mediating role of social anxiety and the moderating role of regulatory emotional self-efficacy (RESE) in this relationship. A three-wave longitudinal investigation with a three-month interval was conducted among 726 adolescents (Mage = 13.47, SD = 0.95; 46.0% girls) from a middle school in North China. The Cross-Lagged Panel Models (RI-CLPMs) were utilized to estimate the associations among the study variables. The results indicated that the incidence rates of NSSI in the three measurements among adolescents were 33.3%, 30.3%, and 24.1%, respectively. Adolescents' rejection sensitivity and NSSI showed a declining trend over time. Furthermore, rejection sensitivity predicted NSSI through the longitudinal mediating effect of social anxiety. RESE played a protective role in adolescents' NSSI, but its moderating effect was not significant. The findings increase our understanding of the association between rejection sensitivity and NSSI in adolescents, and they benefit educators in conducting targeted interventions through improving adolescents' rejection sensitivity and social anxiety to reduce the risk of NSSI.

A Study of the Neurobiological Mechanisms of Non-suicidal Self-injurious Behaviour

Non-suicidal self-injury (NSSI) often occurs in adolescence and early adulthood, accompanied by an increase in the incidence and development of related diseases, making it a significant risk factor for suicide. NSSI behavior among adolescents has become a serious public health issue, threatening their physical and mental development. This article explores the identification methods, biological causes, and emotional causes of NSSI behavior and provides current applicable treatment interventions. By elaborating on the harm of NSSI behavior to adolescents, identification methods, and intervention strategies are proposed to provide a theoretical basis for monitoring and protecting adolescent health in order to improve NSSI behavior among adolescents.

One-year follow-up of neurobehavioral therapy in functional seizures or epilepsy with traumatic brain injury: A nonrandomized controlled trial.

Patients with traumatic brain injury (TBI) often present with seizures (functional and/or epileptic), but treatments for patients with TBI and seizures are limited. We examined treatment phase and 1-year post-enrollment outcomes following neurobehavioral therapy (NBT) for patients with TBI + functional seizures (FS) and TBI + epilepsy. In this multicenter, prospective, three-group, nonrandomized, controlled trial, with 1-year post-enrollment follow-up, three cohorts of adults were recruited: TBI + video-electroencephalography (EEG)-confirmed FS (n = 89), TBI + EEG-confirmed epilepsy (n = 29), and chart/history-confirmed TBI without seizures (n = 75). Exclusion criteria were recent psychotic or self-injurious behavior, current suicidal ideation, pending litigation or long-term disability, active substance use disorder, and inability to participate in study procedures. TBI + FS and TBI + epilepsy groups completed NBT for seizures, an evidence-based, 12-session, multimodal psychotherapy, whereas TBI without seizures participants received standard medical care. The primary outcome was change in seizure frequency; secondary outcomes were changes in mental health, TBI-related symptoms, disability, and quality of life. Reductions in average monthly seizures occurred during treatment in TBI + FS participants (p = .002) and were significant from baseline (mean = 16.75; 95% confidence interval [CI] = 11.44-24.53) to 12 months post-enrollment (mean = 7.28, 95% CI = 4.37-12.13, p = .002, d = .38). Monthly seizures decreased during treatment in TBI + epilepsy participants (p = .002); reductions were not statistically significant from baseline (mean = 2.38, 95% CI = 1.12-5.04) to 12-month postenrollment (mean = .98, 95% CI = .40-2.42, p = .07, d = .22). Regarding treatment-phase changes in secondary outcome measures, TBI + FS participants improved significantly on 10 of 19 variables (52.6%), TBI + epilepsy participants improved on five of 19 (26.3%), and TBI-onlycomparisons improved on only one of 19 (5.3%). NBT benefited patients with TBI + FS and TBI + epilepsy. Improvements were demonstrated at 1 year post-enrollment in those with TBI + FS. NBT may be a clinically useful treatment for patients with seizures.

The trajectory of serum salicylate concentrations after ingestion of medicinal oil containing methyl salicylate

Introduction The toxicokinetics of methyl salicylate after unintentional or intentional ingestion of medicinal oil containing methyl salicylate has not been well studied. We aimed to characterize the trajectory of serum salicylate concentrations and to evaluate factors associated with the peak serum salicylate concentration and the time from ingestion to peak concentration. Methods This was a retrospective cohort study of consecutive patients reported to the Hong Kong Poison Control Centre for laboratory-confirmed methyl salicylate poisoning by all local public emergency departments between 1 July 2008 and 30 June 2023. We analyzed cases with at least three serum salicylate concentrations. Multivariable generalized linear regression was used to identify factors significantly associated with the peak serum concentration and the time from ingestion to peak concentration. Results We included 41 patients (median age 81.0 years; 32 women and nine men). The median time from ingestion to the first peak serum salicylate concentration was 5.6 h (IQR: 3.2–10.8 h). Multiple regression showed that gastric aspiration (adjusted regression coefficient [β] − 2.50; 95% CI: −3.93 to −1.08; P = 0.001) and single-dose activated charcoal (adjusted β − 1.22; 95% CI: −2.02 to −0.42; P = 0.003) were significantly associated with a lower peak concentration, after adjusting for patient age, sex, exposure due to intentional self-harm, reported ingested dose, time from ingestion to emergency department presentation, vomiting, concurrent use of aspirin (acetylsalicylic acid) and other medications that affect gastric emptying or gastric acid secretion, blood pH, serum albumin concentration, and creatinine clearance. Discussion The serum salicylate concentration did not peak as quickly as generally believed, highlighting the importance of continued monitoring. Gastric aspiration and single-dose activated charcoal may help reduce gastrointestinal absorption, but their impact on clinical outcomes remains unclear. Conclusions Given the median time of 5.6 h (IQR: 3.2–10.8 h) from ingestion to the peak salicylate concentration, gastric aspiration and single-dose activated charcoal can be considered in patients up to a few hours after medicinal oil ingestion when the airway is protected.

Impact of mentalization, identity diffusion and psychopathology on nonsuicidal self-injury among adolescents.

Nonsuicidal self-injury (NSSI) has become a major public health issue in adolescents. This cross-sectional case-controlled study aims to assess the impact of identity diffusion, psychopathology, and mentalization on NSSI in adolescence. The study sample consisted of 153 adolescents (76.5% girls; Mage = 15.6 years). The sample included 56 clinical cases of NSSI, 45 psychiatric cases without NSSI, and 52 healthy controls, all recruited in Ankara, Türkiye, from June 1, 2022, to August 31, 2022. Mentalization was assessed by "The Movie for the Assessment of Social Cognition" (MASC) which categorizes mentalizing as "correct mentalizing" "hypermentalizing" "undermentalizing" and "no-mentalizing". All participants filled in the Self-Injurious Behavior Screening Questionnaire, Assessment of Identity Development in Adolescence (AIDA), and Youth Self Report (YSR), and Inventory of Statements About Self-injury (ISAS). The NSSI group showed lower mentalizing capacity than the healthy control group (p = .011), and more no-mentalizing errors than the other two groups (p = .014). Identity diffusion scores were higher in the NSSI group than in the other two groups (p < .001). Multivariate logistic regression analysis showed that the presence of maternal psychiatric disorder (p = .019, OR = 5.21), identity diffusion (p = .007, OR = 1.02), no mentalizing (p = .049, OR = 1.28), and total psychopathology symptoms (p = .009, OR = 1.12) had a significant impact on NSSI. Current findings suggest that transdiagnostic approaches, including mentalization and identity diffusion, may contribute to a more comprehensive understanding of NSSI and to the development of clinical interventions.

Characteristics of children and adolescents with recurrent mental health emergency visits and clinicians' intervention tendencies.

Mental disorders affect approximately 15%-20% of childhood. However, due to various factors, these individuals do not benefit sufficiently from mental health services. Therefore, psychiatry emergency services become a key system in the need of psychiatric care for these children. This study aims to reveal the factors that predict recurrent admissions in children and adolescents admitted to the emergency department of a psychiatric hospital and the tendencies of clinicians during management. In our study, the data of patients aged 0-18 years who applied to the emergency department between 1 March 2022 and 01 March 2023 were scanned retrospectively. Participants who applied once were included in the 'single applicant' group, whereas patients who applied two or more times were included in the 'repeated applicants' group. A total of 1563 emergency applications were recorded by 785 different patients. A total of 62.2% of the patients visited the emergency department once, while 37.8% applied two or more times. Non-suicidal self-injury, delusion/hallucination, irritability and depression were significantly higher in recurrent applicants (P < 0.05). Psychotic disorder, bipolar disorder, major depression and borderline personality traits were significantly frequent in these patients (P < 0.05). Additionally, it was determined that the number of psychiatric diagnoses, referral time, need for chemical restraint, having a diagnosis of psychotic disorder or borderline personality traits increased the likelihood of recurrence. Our results indicate some special risk factors that increase the likelihood of recurrent emergency admissions in children and adolescents. Further research with larger sample sizes may elucidate the unique needs of these children in order to use of community resources beneficially.

Implicit associations with non-suicidal self-injury: Examination in a clinical sample by borderline personality symptomatology.

We examine correlates and predictors for implicit associations with non-suicidal self-injury (NSSI) with the Self-Injury Implicit Association Test (SI-IAT) in a treatment-seeking sample. We also examine group differences in the SI-IAT among those with low/none, moderate and high/clinically significant borderline personality disorder (BPD) symptomatology in a treatment-seeking sample. Participants (N = 111; 58% female; 89% White; Mage = 30.25) completed the SI-IAT and self-report measures at two time points. Higher BPD symptom scores were significantly, positively correlated with implicit identification with NSSI, and predicted NSSI identity when controlling for depression indices, history of NSSI and other covariates. With Time 1 SI-IAT scores entered as a covariate, BPD scores no longer significantly predicted Time 2 SI-IAT scores. Individuals with moderate and high/clinically significant symptom counts of BPD had higher/stronger implicit associations with NSSI identity than those with no/low BPD symptoms. Individuals with symptoms of BPD may implicitly identify with NSSI more than other clinical groups; examination of implicit assessments in BPD in future research is needed to further explore implicit identification with NSSI in this patient group to further understand both cross-sectional and prospective relations.

Longitudinal relations between non-suicidal self-injury and both depression and anxiety among senior high school adolescents: a cross-lagged panel network analysis.

Comorbidity between non-suicidal self-injury (NSSI) and depression and anxiety was common. In the framework of network theory, the examination of directionality and gender differences in longitudinal relationships at the symptom level made a significant contribution to the understanding of comorbidity. Therefore, this study employed cross-lagged panel network analysis to investigate the longitudinal interrelations between NSSI and depression and anxiety in Chinese adolescents, with a focus on gender differences. The study was conducted with a sample of 884 senior high school students (F/M: 481/403; mean age: 15.19±0.48 years) from Jinchang City, Gansu Province, China. All respondents completed the Adolescent Non-Suicidal Self-Injury Assessment Questionnaire and the two subscales (depression and anxiety) of the Brief Symptom Inventory at two intervals. The data were estimated in R 4.2.0 to construct the cross-lagged panel network (CLPN). The CLPN results uncovered the gender differences. For boys, self-hitting and feeling scared emerged as central symptoms. Cutting predicted subsequent feelings of sadness (β=-0.57), tension (β=-0.52) and indifference (β=-0.49), potentially serving as a bridge connecting NSSI to depression and anxiety. For girls, biting themselves and feeling scared were central symptoms. Carving and skin rubbing predicted subsequent feelings of indifference (β=-0.31, -0.21), bridging NSSI to depression and anxiety. In addition, feeling scared emerged as the key bridge symptom connecting depression and anxiety. The findings showed the gender-specific developmental characteristics of the directional relations between NSSI and depression and anxiety at the symptom level. They provided new insights into the comorbidity of NSSI and depression and anxiety, carrying important implications for the screening and intervention of adolescent NSSI.

Neuromuscular Electrical Stimulation Under Deep Sedation Reduces the Incidence of ICU-Acquired Weakness in Critically Ill Patients With COVID-19 With Acute Respiratory Distress Syndrome.

The COVID-19 pandemic has led to an unprecedented increase in cases of acute respiratory distress syndrome (ARDS). In such cases, deep sedation using sedatives and muscle relaxants is commonly used to prevent patient self-inflicted lung injury during the early phase. However, such sedation limits the ability to perform early rehabilitation, leading to ICU-acquired muscle weakness (ICU-AW) and a worse prognosis. This study aimed to clarify the preventive effect of neuromuscular electrical stimulation (NMES) during deep sedation on ICU-AW and physical function at discharge in critically ill patients with COVID-19 with ARDS. A retrospective, single-center study was conducted on patients admitted to the ICU or advanced critical care center with severe COVID-19 with ARDS between March 1, 2020, and March 31, 2022. Patients who were managed with the Richmond Agitation-Sedation Scale between -4 and -5 for at least three days were included. Patients in the NMES group received NMES within two days of deep sedation, whereas those in the non-NMES group did not. The primary endpointwasthe incidence of ICU-AW at discharge from the ICU, and the secondary endpoints included physical activity levels, skeletal muscle mass index, time to active mobilization, and Barthel index (BI) at discharge. Statistical analyses included Pearson's chi-squared test, Fisher's exact test, and multiple logistic and linear regression analyses. Of the 129 patients, 68 (54 males and 14 females) were included after applying the exclusion criteria, with 38 in the NMES group and 30 in the non-NMES group. The incidence of ICU-AW was significantly lower in the NMES group (28.95% vs. 56.67%, p = 0.0211). NMES implementation (OR: 0.20, p = 0.03), ventilator weaning (OR: 0.10, p = 0.01), and duration of deep sedation (OR: 0.81, p < 0.01) were significant predictors of ICU-AW. Higher ICU Mobility Scale scores and shorter time to active mobilization were associated with a higher BI at discharge. Early rehabilitation using NMES during deep sedation may prevent ICU-AW in critically ill patients with COVID-19 with ARDS. NMES is associated with a reduced risk of ICU-AW and improved functional independence at discharge. This procedure can be safely performed in sedated patients and may help prevent ICU-AW, supporting early mobilization strategies in ARDS rehabilitation.
