Traumatic Brain Injury and Risk of Schizophrenia and Other Non-mood Psychotic Disorders: Findings From a Large Inpatient Database in the United States.

BACKGROUND: Traumatic brain injury (TBI) is linked with an increased risk of schizophrenia and other non-mood psychotic disorders (psychotic disorders), but the prevalence and contributing factors of these psychiatric conditions post-TBI remain unclear. This study explores this link to identify key risk factors in TBI patients. METHODS: We used the 2017 National Inpatient Sample dataset. Patients with a history of TBI (n = 26 187) were identified and matched 1:1 by age and gender to controls without TBI (n = 26 187). We compared clinical and demographic characteristics between groups. The association between TBI and psychotic disorders was explored using the logistic regression analysis, and results were presented as Odds ratio (OR) and 95% confidence interval (CI). RESULTS: Psychotic disorders were significantly more prevalent in TBI patients (10.9%) vs controls (4.7%) (P < .001). Adjusted odds of psychotic disorders were 2.2 times higher for TBI patients (95% CI 2.05-2.43, P < .001). Male TBI patients had higher psychotic disorders prevalence than females (11.9% vs 8.4%). Younger age, bipolar disorder, anxiety disorders, substance abuse, personality disorders, and intellectual disability are associated with an increased risk of psychotic disorders in men. CONCLUSION: Our study found that hospitalized TBI patients had 2.2 times higher odds of Schizophrenia non-mood psychotic disorder, indicating an association. This highlights the need for early screening of psychotic disorders and intervention in TBI patients, calling for more research.

Bullying Victimization in Children and Adolescents and Its Impact on Academic Outcomes.

ABSTRACT: Bullying victimization has been identified as a significant factor influencing academic outcomes. We sought to evaluate the educational outcomes and psychiatric comorbidities in children and adolescents who are victims of bullying using the National Survey of Children's Health dataset for the study. The participants were children and adolescents (age: 6-17 years) categorized into two groups: group 1, not bullied (n = 21,015), and group 2, bullied more than once (n = 21,775). Individuals whose health status was fair or poor have experienced more bullying (2.4% vs. 1.4%, p < 0.001). Individuals in the group 2 were more likely to repeat the grades than the group 1 (7.1% vs. 5.9%, p = 0.039). Individuals who were missing ≥11 school days and sometimes or never engaged in school were observed to be more in the group 2 compared with the group 1 (5.9% vs. 3.2% and 20.3% vs. 10.6%, p < 0.001). In conclusion, bullying victimization could be a risk factor and associated with decreased academic outcomes.

Mental health outcomes and suicidality in hospitalized transgender adolescents: A propensity score-matched Cross-sectional analysis of the National inpatient sample 2016-2018.

Transgender adolescents have unique mental health needs. This demographic has increased rates of mood disorders, anxiety, and depression compared to their cisgender peers. Large-scale studies focused on mental health outcomes, including suicidality, in the transgender adolescent population remain unknown. This study tries to fill these gaps in the literature. Data for this study was taken from the National Inpatient Sample 2016-2018. Transgender adolescents were identified using the ICD-10 codes related to transsexualism diagnoses. These individuals were compared to adolescents without transsexualism diagnoses. To mitigate imbalances in baseline characteristics, we utilized a 1:2 nearest neighbor propensity score matching with a caliper width of 0.0001, considering variables such as age, year of hospitalization, and psychiatric disorders. Following propensity score matching, the study cohort comprised 2635 transgender and 5270 non-transgender adolescents (Mean age 15.2 years). The transgender group demonstrated a notably higher prevalence of mood disorders (91%) and anxiety disorders (65%). Furthermore, the prevalence of suicidal ideation was significantly higher in the transgender group (52.4% vs. 39.2%, p < 0.001). However, there was no significant difference in the prevalence of suicide attempts between the groups. After controlling for psychiatric comorbidities, age, and gender, the odds ratio for the composite outcome of suicidal ideation or attempt was 1.99 (95% CI 1.58-2.12, p < 0.001). Our study identifies elevated mood and anxiety disorders and suicidality rates in hospitalized transgender adolescents compared to cisgender peers. Mood disorders notably amplify the risk of suicidal attempts. These findings urgently call for targeted mental health interventions and policy changes to serve this vulnerable population in healthcare settings better.

Mixed Connective Tissue Disease Presenting With Psychosis-A Case Report.

ABSTRACT: Mixed connective tissue disease (MCTD) is a systemic autoimmune disease with features overlapping multiple autoimmune disorders. One study found that over 55% of patients with MCTD experienced neuropsychiatric symptoms, the most common of which was an "aseptic meningitis-like syndrome." We present a case of a 17-year-old adolescent girl presenting with abnormal speech and behavior, auditory hallucinations, and paranoid delusions after an isolated episode of fever. She was treated for her psychotic symptoms but later developed symptoms resembling neuroleptic malignant syndrome. An antibody screen revealed elevated anti-U1-ribonucleoprotein antibodies with a possible diagnosis of MCTD. She finally responded to steroid therapy. To our knowledge, this is the first reported case of MCTD initially presenting with psychosis. A diagnosis of autoimmune disorders should be kept in the differential of similar clinical presentations including connective tissue disorders and autoimmune thyroid conditions.

Prevalence of Psychiatric Disorders Among Children and Adolescents in Child Welfare Custody Admitted to the Hospital: A Nationwide Inpatient Sample Analysis.

Objective: To assess the prevalence of psychiatric disorders among children and adolescents in child welfare custody admitted to the hospital.Methods: Data were collected from the 2016-2017 National Inpatient Sample of the US population of general hospital admissions. Data for patients aged 12-17 years who were in child welfare custody were obtained using the ICD-10 diagnosis code Z6221: child in welfare custody. The control group comprised patients not in child welfare custody. Groups were compared for demographic, clinical, and hospital characteristics.Results: The study group included 879 child welfare patients, of whom 38.9% were male, with a mean age of 14.7 years. The control group comprised 222,494 patients, of whom 41.2% were male, with a mean age of 14.9 years. In the study group, 69.4% of patients had mood disorders compared to 28.6% in the control group. Half of the patients in the study group had anxiety disorders and almost 44% had ADHD and other conduct disorders compared to 19.3% and 14.2%, respectively, in the control group. Prevalence of suicidal ideation/attempt was almost 3 times higher in the study group compared to controls (41.0% vs 14.8%), and 18.3% of study group patients had a substance use disorder compared to 8.3% of controls. Mood disorders were the most common reason for hospitalization (44.8% vs 19.2%), followed by ADHD/other conduct disorders (5.3% vs 1.1%) and anxiety disorders (4.9% vs 0.9%).Conclusions: Children and adolescents in the child welfare system are associated with a higher risk of mental health problems. More studies are needed to identify the factors that contribute to psychiatric comorbidities in this population and to determine and address the factors that can prevent mental health issues.Prim Care Companion CNS Disord 2023;25(6):22m03238.

A synaptic corollary discharge signal suppresses midbrain visual processing during saccade-like locomotion.

In motor control, the brain not only sends motor commands to the periphery, but also generates concurrent internal signals known as corollary discharge (CD) that influence sensory information processing around the time of movement. CD signals are important for identifying sensory input arising from self-motion and to compensate for it, but the underlying mechanisms remain unclear. Using whole-cell patch clamp recordings from neurons in the zebrafish optic tectum, we discovered an inhibitory synaptic signal, temporally locked to spontaneous and visually driven locomotion. This motor-related inhibition was appropriately timed to counteract visually driven excitatory input arising from the fish's own motion, and transiently suppressed tectal spiking activity. High-resolution calcium imaging revealed localized motor-related signals in the tectal neuropil and the upstream torus longitudinalis, suggesting that CD enters the tectum via this pathway. Together, our results show how visual processing is suppressed during self-motion by motor-related phasic inhibition. This may help explain perceptual saccadic suppression observed in many species.

Prevalence of Psychiatric Comorbidities in Patients With Neurofibromatosis.

Objective: To assess the prevalence of psychiatric comorbidities in patients with neurofibromatosis.Methods: In this cross-sectional study, we used the 2010-2014 National Inpatient Sample database. Patients ≥ 18 years of age with a primary or secondary diagnosis of neurofibromatosis and psychiatric comorbidities were queried.Results: A total of 43,270 patients with a mean age of 48.7 years (female: 55.7%, White: 70.1%) were included in the study. Overall, psychiatric comorbidities were present in 46.5% of patients; mood disorders (22.1%) and anxiety disorders (12.2%) were the most prevalent comorbidities. Although previous studies report prevalence rates of attention-deficit/hyperactivity disorder in up to 50% of patients with neurofibromatosis, our study found that the rate was much lower at 1.10%. Female sex and non-White race were less associated with psychiatric comorbidities (odds ratio = 0.868 [P = .003] and 0.689 [P < .001], respectively). The moderate-to-extreme loss of function illness severity category was associated with 1.35-times higher odds of having psychiatric comorbidities compared to mild-to-moderate or no loss of function (P < .001). The total length of stay was similar in patients with and without psychiatric comorbidities (mean = 4.98 [95% CI, 4.72-5.24] vs mean = 4.83 [95% CI, 4.60-5.07], respectively; P = .34).Conclusions: In adult patients with neurofibromatosis, 46.5% were found to have at least one psychiatric comorbid diagnosis. The most frequent psychiatric comorbid disorders were mood disorders and anxiety disorders. Female sex and non-White race predicted a lower likelihood of having a psychiatric disorder.Prim Care Companion CNS Disord 2023;25(5):23m03514.

Shortage of Mental Health Professionals Doing Research: A Cause for Concern.

ABSTRACT: Research plays a crucial role in advancing health care. Physician scientists, who bring together clinical and scientific perspectives, are integral to this effort. However, the pursuit of research careers among physicians has declined due to several obstacles, including inadequate support, training, time, and financial constraints. Emergency medicine and psychiatric specialties receive less support than other specialties, and COVID-19 has worsened the challenges. The COVID-19 has made things harder for physician scientists, increasing clinical demands and causing research delays. To tackle this, future physician scientists should receive organized training that includes mandatory research activities during their training. Large-scale studies should identify barriers to research and offer mentoring for young physician scientists. Encouraging female researchers and involving research faculty in residency training is crucial. Collaboration between physician and PhD researchers is essential for the future of medical research. It is vital to address these to advance health care and improve mental health outcomes.

A Drosophila glial cell atlas reveals a mismatch between transcriptional and morphological diversity.

Morphology is a defining feature of neuronal identity. Like neurons, glia display diverse morphologies, both across and within glial classes, but are also known to be morphologically plastic. Here, we explored the relationship between glial morphology and transcriptional signature using the Drosophila central nervous system (CNS), where glia are categorised into 5 main classes (outer and inner surface glia, cortex glia, ensheathing glia, and astrocytes), which show within-class morphological diversity. We analysed and validated single-cell RNA sequencing data of Drosophila glia in 2 well-characterised tissues from distinct developmental stages, containing distinct circuit types: the embryonic ventral nerve cord (VNC) (motor) and the adult optic lobes (sensory). Our analysis identified a new morphologically and transcriptionally distinct surface glial population in the VNC. However, many glial morphological categories could not be distinguished transcriptionally, and indeed, embryonic and adult astrocytes were transcriptionally analogous despite differences in developmental stage and circuit type. While we did detect extensive within-class transcriptomic diversity for optic lobe glia, this could be explained entirely by glial residence in the most superficial neuropil (lamina) and an associated enrichment for immune-related gene expression. In summary, we generated a single-cell transcriptomic atlas of glia in Drosophila, and our extensive in vivo validation revealed that glia exhibit more diversity at the morphological level than was detectable at the transcriptional level. This atlas will serve as a resource for the community to probe glial diversity and function.

Role of Minocycline as an Adjunct Neuroinflammatory Modulator in Treatment-Resistant Depression: A Systematic Review of Randomized Controlled Trials.

Objective: To assess the efficacy and safety evidence for adjunct minocycline in treatment-resistant depression (TRD).Data Sources: In this systematic review, PubMed, PubMed Central, Embase, and Google Scholar were searched from inception to October 2022. The following keywords were utilized in the search: "depression" AND "minocycline" AND "treatment, pharmacological intervention, management." Medical Subject Heading terms for "minocycline" and "depression, depressive disorder, treatment-resistant," and "disease management" were also used. Relevant peer-reviewed, English-language articles that included adults and children were selected for final evaluation.Study Selection: Two authors independently searched and selected 1,004 relevant articles. Only randomized controlled trials were considered. Five articles were identified that fulfilled the inclusion criteria.Data Extraction: The PICO algorithm (Population, Intervention, Comparison, Outcomes, and Study Design) framework was utilized, and Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria guidelines were followed. The Cochrane risk of bias tool was used to categorize the included study as a low, unclear, or high risk of bias.Results: Minocycline as an adjunct immunomodulator shows inconsistent benefit in TRD. Minocycline has some beneficial effect on depression scale scores and inflammatory markers in TRD patients with inflammatory disequilibrium (C-reactive protein elevation exceeds 3 mg/L). However, minocycline showed an inconclusive effect in TRD with no clear immunologic dysregulation. Minocycline might have a neuroprotective, rather than therapeutic, effect at a small dose.Conclusions: The results were inconsistent regarding the clinical and neuroprotective role of minocycline in TRD. More study is needed to clarify the pathophysiologic and clinical role of minocycline as an immunomodulator in TRD.Prim Care Companion CNS Disord 2023;25(5):22r03467.

Efficacy of Cognitive Behavioral Therapy for Insomnia for the Treatment of Child and Adolescent Anxiety and Depression: A Systematic Review From Randomized Controlled Trials.

ABSTRACT: Cognitive behavioral therapy for insomnia (CBT-I) has shown promising results in the adult population. However, there is not enough evidence for children and adolescents. Hence, we evaluated the current evidence of CBT-I in the treatment of anxiety and depression in children and adolescents. Published randomized clinical trials published before June 2020 were searched from PubMed, Cochrane Library of database, clinicaltrials.gov, and Google Scholar. Out of seven included studies, six studies assessed the effect of CBT-I on depression, and five assessed the effect on anxiety. In this review, most studies in this review showed a strong effect of CBT-I on symptoms of depression. Although a positive effect of CBT-I on anxiety was noted, only a small number of studies have considered this management. These findings should be considered preliminary, and further large-scale studies are warranted to further explore this finding further.

Sexual Abuse and Its Impact on Suicidal Ideation and Attempts and Psychiatric Illness in Children and Adolescents With Posttraumatic Stress Disorder.

Objective: Sexual abuse in minors aged 6-17 years is a significant public health concern. Victims of sexual abuse are at risk of developing complex psychopathology and chronic suicidal thoughts. Posttraumatic stress disorder (PTSD) develops in one-third of minors with a history of sexual abuse. The primary objective of this study was to assess the baseline characteristics of minors with PTSD and a history of sexual abuse (PTSD+S) compared with minors with PTSD without sexual abuse (PTSD only). The secondary objective was to evaluate the psychiatric comorbidities and suicidal ideation/attempts between the groups.Methods: The National Inpatient Sample database from 2006 to 2014 was analyzed using the ICD-9 code for PTSD and history of sexual abuse. PTSD+S (n = 251) subjects were compared with those with PTSD only (n = 24,243) using t test and χ2 test. Univariate and multivariate logistic regression analyses were performed with suicidal behavior (suicidal ideation/attempt) as the outcome and PTSD with and without sexual abuse, sex, age, and other psychiatric comorbid conditions as independent variables.Results: More patients in the PTSD+S group were nonwhite (52% vs 42%, P < .001) and female (81% vs 66%, P < .001) compared to PTSD only patients. Also, more patients were Hispanic in the PTSD+S group compared to the PTSD only group (28% vs 13%). Major depressive disorder (MDD; 23% vs 14%, P < .001) and substance use disorder (SUD; 20% vs 11%) were more commonly diagnosed psychiatric comorbidities in the PTSD+S group (P < .001). Suicidal behavior (suicidal ideation/attempt) was higher in the PTSD+S group than in PTSD only patients (36% vs 30%, P = .05). Overall, the risk of suicidal behavior was 29% higher in the PTSD+S group than in PTSD only patients (odds ratio [OR] = 1.29, P = .05). In the multivariate analysis, after controlling for age and sex, comorbid diagnosis of MDD (OR = 1.66, P < .001) and SUD (OR = 1.18, P < .001) was associated with increased suicidal behavior. However, PTSD+S showed no association with suicidality (OR = 1.16, P = .29) in the multivariate analysis.Conclusions: Sexual abuse is associated with PTSD and higher risk of comorbid psychiatric illnesses, including MDD, SUD, and suicidal behavior. In-depth research on the relationship between child and adolescent sexual abuse and chronic suicidality is warranted.

Suicide Risk Among Adolescents With ADHD: An Overview From the National Inpatient Sample Data Set.

ABSTRACT: Studies have shown an association between attention deficit hyperactivity disorder (ADHD) and suicide; however, it has not been studied from inpatient hospitalization data among adolescents. For this study, data from the National Inpatient Sample data set were used. Based on the diagnosis of ADHD, the patient sample was stratified into two groups. Study group was composed of patients with ADHD, and control group was selected by propensity score matching (1:1), which composed of patients without ADHD. The primary outcome was suicidal ideation/attempt between the groups. Prevalence of SI was 25.1% in patients with ADHD versus 10.3% among patients without ADHD. Prevalence of SA was also very high (8.0% vs 3.9%) among patient with ADHD compared with non-ADHD group. After controlling for covariates, ADHD was a strong predictor of suicidal ideation/attempt with an odds ratio of 2.18. It is important to screen for suicidality in patient with ADHD given the high prevalence of suicidality.

Homicidal ideation and psychiatric comorbidities in the inpatient adolescents aged 12-17.

Objectives: Adolescents with a homicidal tendency is a growing concern in the United States. Studies in the past have showcased the relationship between homicidal ideation (HI) and psychiatric illnesses, but very limited information is available on the adolescent and inpatient population. We aim to evaluate the prevalence of demographic characteristics and psychiatric disorders in adolescents with and without HI. Materials and methods: Adolescent (age 12-17) population admitted to the hospital with the diagnosis of homicidal ideation was identified from the 2016-2018 National Inpatient Sample Dataset (NISD). Patients without HI were defined as the control group. The prevalence of psychiatric comorbidities between the groups was compared by applying the Rao-Scott adjusted chi-square test. We used multivariable logistic regression to generate odds ratio (OR) of homicidal ideation as an outcome; we adjusted age, sex, race, socioeconomic status, substance use disorders, alcohol use disorders, and psychiatric comorbidities. Results: A total of 18,935 patients (mean age: 14.5) with HI diagnosis were identified in this study. Majority of the patients were male subjects in the HI group compared to the control group (58.7 vs. 41.2%, p < 0.001). Racially, HI was more prevalent in white race (56.0 vs. 52.6%, p < 0.001) and black race (22.3 vs. 17.8%, p < 0.001), compared to Hispanic race (14.9 vs. 21.3%, p < 0.001). Major depression (Odds ratio [OR]: 2.66, p < 0.001), bipolar disorder (OR: 3.52, p < 0.001), anxiety disorder (OR: 1.85, p < 0.001), ADHD, and other conduct disorders (OR: 4.01, p < 0.001), schizophrenia (OR: 4.35, p < 0.001) are strong predictors of HI. Suicidality was prevalent in 66.9% of patients with HI. Conclusion: We found a higher prevalence of psychiatric illnesses such as depression, anxiety, and bipolar disorder in adolescents with homicidal ideation in the inpatient setting. White and black races were more prevalent in patients with homicidal ideation. Further large-scale longitudinal research studies are warranted to establish the correlation between psychiatric disorders and homicidal ideation among adolescents.

Psychiatric Disorders in Hospitalized Homeless Individuals: A Nationwide Study.

Objective: To compare the incidence of inpatient psychiatric admissions and evaluate the prevalence of psychiatric disorders among homeless individuals.Methods: This cross-sectional study utilized the Nationwide Inpatient Sample dataset for the year 2016-2017. US adult homeless patients (age ≥ 18 years) admitted to the hospital were age and sex matched (1:1) with non-homeless individuals using the propensity score matching technique.Results: The study included a total of 614,390 homeless patients (mean age = 46.1 years, 71.9% male). Most of the homeless patients were Black (24.8% vs 17.3% of the non-homeless population). Mood, anxiety, and psychotic disorders were highly prevalent in homeless patients compared to those who were non-homeless (P < .001). Composite of psychiatric disorders was also significantly higher in the homeless group (64.9% vs 29.1%, P < .001). Suicidal ideation was present in 19.4% of the homeless individuals and in 2.9% of the non-homeless (P < .001). Hospital admissions related to any psychiatric condition were 33.9% in the homeless and 6.7% in the non-homeless (P < .001). Compared to the non-homeless, homeless patients admitted for psychiatric disorders had longer inpatient psychiatric admissions (8.7 vs 7.7 days, P < .001).Conclusions: The results revealed a positive association between homelessness, comorbid psychiatric disorders, and suicidal ideations/attempts. Appropriate psychiatric screening measures are needed for the homeless. Homelessness is associated with longer inpatient psychiatric stay. The challenges faced in treating and preventing mental illness in the homeless should be investigated further.

The role of metformin in treatment of weight gain associated with atypical antipsychotic treatment in children and adolescents: A systematic review and meta-analysis of randomized controlled trials.

Introduction: Second-generation antipsychotics are associated with significant weight gain. The aim of this systematic review and meta-analysis was to determine the efficacy and safety of metformin for the treatment of weight gain in children and young adults treated with second-generation antipsychotics. Methods: We followed PRISMA guidelines to evaluated studies published before March 2020 in Medline, Google Scholar, PubMed, Cochrane library database, annual scientific sessions of the American Psychiatric Association, American Academy of Child and Adolescent, Psychiatry, and American Society of Clinical Psychopharmacology. Studies included compared metformin with the placebo for management of weight gain in children and adolescents taking atypical antipsychotics. Non-randomized studies, animal experiment studies, editorials, and review studies were excluded. Multiple parameters, including change in anthropometric-biochemical parameters, drug discontinuation rate, and side effects among the groups were assessed. The random-effects method was used for meta-analysis. Results: Four studies with were included in the final analysis (213 patients; metformin: 106; control: 107). After pooled analysis, 12-16 weeks of metformin therapy was associated with a significant reduction in weight [(mean difference (MD): -4.53 lbs, confidence interval (CI): -6.19 to -2.87, p-value < 0.001)], and BMI z score [MD, -0.09, CI: -0.16, -0.03, p-value: 0.004] compared to control. Metformin was also associated with a significant reduction in insulin resistance [MD: -1.38, CI: -2.26 to -0.51, p-value: 0.002]. There were higher odds of nausea-vomiting [OR: 4.07, CI: 1.32-12.54, p-value: 0.02] and diarrhea [OR: 2.93, CI: 1.50-5.71, p-value: 0.002] in the metformin group. However, there was no difference in drug discontinuation rate [OR: 1.45, CI: 0.41-5.06, p-value: 0.56]. Conclusion: Metformin may prove beneficial in the treatment of weight gain in children treated with second-generation antipsychotics. The pooled treatment effect showed a significant reduction in BMI Z-score and weight in just 12-16 weeks. The limitations include small sample size, variation in metformin dose, and duration of treatment. This meta-analysis should be interpreted as promising, and further larger studies are warranted before drawing a conclusion.
