ABSTRACT Background Multiple meta‐analyzes suggest that acne improvement with isotretinoin leads to improved mental health outcomes in adults, though isotretinoin‐related psychiatric data, including for suicidality, are limited for adolescents. Methods PubMed, MEDLINE, EmBase, PsychINFO, and the Cochrane Library databases were searched for papers published between 1982 and September 2024 that reported suicidality following isotretinoin treatment for acne vulgaris in adolescents aged 18 or younger. Results A total of 24 full text articles were reviewed. Despite numerous case reports describing suicidal ideation, suicide attempts, and completed suicides were rare. Databases suggest that adolescents taking isotretinoin are the group with the most suicide attempts, but epidemiological studies including matched controls suggest this could be a function of the number of prescriptions in this population. Observational, cohort, and case‐time‐control studies did not consistently report an increased risk of suicidality with isotretinoin. When compared with those prescribed antibiotics, isotretinoin‐prescribed adolescents had no increase in suicidality during treatment but had a higher prevalence of suicidal behavior in the year after treatment. If patients prescribed isotretinoin developed suicidal ideation, it was more likely to develop early in or following completion of treatment. Conclusion There exists a conventionally held belief in the association between isotretinoin use and suicidal ideation for adolescent patients, but this narrative review does not indicate a consistent relationship.

Importance Suicide is a leading cause of death among young people and an escalating public health crisis. Objective To assess the effectiveness and harms of available treatments for suicidal thoughts and behaviors among youths at heightened risk for suicide. Evidence Review A systematic review was conducted searching databases including MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Scopus, and various gray literature sources from January 1, 2000, to September 26, 2024. We included randomized clinical trials, comparative observational studies, and before-after studies of psychosocial interventions, pharmacologic interventions, neurotherapeutics, emerging therapies, and combination therapies. Eligible patients were youths (aged 5-24 years) with heightened risk for suicide, adolescents from racial and ethnic minority groups known to be at increased risk of suicide, or those exposed to crime or violence. Pairs of independent reviewers selected and appraised studies. Findings This review included 65 studies (33 randomized clinical trials, 13 comparative observational studies, and 19 before-after studies) reporting on 14 534 patients (median age, 15.1 years; 75.1% female patients). Psychosocial interventions comprised psychotherapy interventions (33 studies; cognitive behavioral therapy, dialectical behavioral therapy, collaborative assessment and management of suicidality, dynamic deconstructive psychotherapy, attachment-based family therapy, and family-focused therapy), acute (ie, 1-4 sessions or contacts) psychosocial interventions (19 studies; safety planning, family-based crisis management, motivational interviewing crisis interventions, continuity of care after crisis, and brief adjunctive treatments), and school- or community-based psychosocial interventions (13 studies; social network interventions, school-based skills interventions, suicide awareness or gatekeeper programs, and community-based, culturally tailored adjunct programs). Dialectical behavior therapy showed moderate strength of evidence for reducing suicidal ideation. Other categories of psychosocial treatments showed insufficient to low strength of evidence for reducing suicidal outcomes. None of the studies evaluated adverse events. The evidence base on pharmacologic treatment for youths at risk of suicide was largely nonexistent. Conclusions and Relevance This systematic review found that the current evidence on available interventions targeting youths at heightened risk of suicide is uncertain. Medication, neurotherapeutics, and emerging therapies remain unstudied among this population. The limited evidence base calls for the development of novel, developmentally and trauma-informed treatments, as well as multilevel interventions to target the increasing suicide risk among youths.

ABSTRACT Background Despite the classic Kraepelinian dichotomy between bipolar disorder (BD) and schizophrenia (SZ), contemporary evidence suggests shared antecedent risk factors and similarities in the early course. This study aimed to identify distinct trajectories leading to first‐episode mania (FEM) and first‐episode psychosis (FEP) by examining antecedent psychopathology, including psychiatric diagnoses, symptoms, substance use, and psychotropic medication exposure. Methods Individuals born after 1985 who resided in Olmsted County, Minnesota, USA, and had FEM/FEP were identified through the Rochester Epidemiology Project. Latent class analysis (LCA) was used to identify subgroups based on antecedent psychopathology incorporating 57 dichotomous antecedent measures before FEM/FEP. Results A total of 202 individuals ( BD n = 73, SZ n = 129; 26.7% female, mean age 20.8 ± 3.7 years) were included. A 3‐class LCA model optimally fits the data. Class 1 (Neurodevelopmental, 29.7%) had a high prevalence of neurodevelopmental disorders, behavioral symptoms, and ADHD medication use. Class 2 (Depressive‐Anxious, 31.2%) included depressive and anxiety disorders, mood‐related symptoms, and SSRI / SNRI use. Class 3 (Minimal Psychiatric Morbidity, 39.1%) had a low prevalence of antecedent diagnoses and symptoms, with comparable substance use to other classes. There were significant diagnostic differences, with SZ being more common in the Neurodevelopmental (71.7%) and Minimal Psychiatric Morbidity (70.9%) classes, while BD was more common in the Depressive‐Anxious class ( p = 0.007). Neurodevelopmental and Minimal Psychiatric Morbidity classes had higher proportions of males (85.0% and 82.3%, respectively) compared to the Depressive‐Anxious class (50.8%, p < 0.001). The Neurodevelopmental class showed an earlier age at first mental health visit (9.5 ± 5.5 years) and a longer antecedent illness duration (10.8 ± 6.1 years) than the other classes ( p < 0.001). Conclusion This study identified three distinct pathways to FEM and FEP, offering a transdiagnostic perspective on the antecedent illness trajectories of BD and SZ. Future research should validate these categories that are more inclusive than the classic BD versus SZ dichotomy and explore their potential for predicting illness course and guiding personalized early interventions.

ImportanceThe rates of suicide and suicide attempts are rising precipitously among early adolescents aged 10 to 14 years in the US. While suicide attempts in this age group are more common and associated with lower lethality than in older age groups, very little is known about these individuals’ long-term social and psychiatric outcomes.ObjectivesTo examine the adult outcomes of individuals making index suicide attempts that came to medical attention between the ages of 10 and 14 years.Design, Setting, and ParticipantsThis population-based cohort constitutes a subsample (n = 164) of a previously reported retrospective-prospective study examining individuals who made index suicide attempts during a 22-year period (1986-2007) in Olmsted County, Minnesota.Main Outcomes and MeasuresTo collect outcome measures, the medical records of all individuals were queried until March 31, 2023, comprising up to 36 years of follow-up data after the index attempt. Measures included current social, psychiatric, and mortality outcomes as well as lifetime measures of psychiatric hospitalizations and repeat suicide attempts. K-means clustering generated adult groupings based on aggregates of psychiatric hospitalizations and repeat attempts. Multivariable logistic regression identified index attempt factors associated with poor adult outcomes.ResultsOf 164 individuals aged 10 to 14 years who made index attempts (128 [78.0%] female; mean [SD] age at index attempt, 13.7 [1.1] years), 3 (1.8%) died on the index attempt. In the follow-up period, no individuals died by suicide. K-means clustering generated a 2-group solution reflecting low (120 [80%]) and high (30 [20%]) rates of adult psychopathology. While a minority of the sample belonged to the high-rate group, characterized by multiple repeat attempts and hospitalizations, the majority had favorable social indicators and fewer reattempts and hospitalizations. Poor adult outcomes were associated with being male (odds ratio, 2.44; 95% CI, 1.00-5.80; P = .04) and having a psychiatric diagnosis prior to the index attempt (odds ratio, 3.27; 95% CI, 1.42-8.07; P = .007).Conclusions and RelevanceIn this sample of early adolescents with index suicide attempts followed into adulthood, all who died by suicide did so on the index attempt. While a small number of individuals went on to develop chronic severe psychopathology, the majority demonstrated little evidence of long-term impairment. Given this discrepancy, future studies should focus on using risk stratification after index attempts to direct postvention resources toward adolescents more susceptible to poor outcomes.

AbstractBackgroundIsotretinoin treatment for acne can reduce adverse psychiatric outcomes in adults, but there has been little investigation of the incidence of psychiatric outcomes in treated adolescents.MethodsThis retrospective cohort study using the Rochester Epidemiology Project identified 606 patients aged 12–18 prescribed isotretinoin over a 10‐year period between January 1, 2008 and December 31, 2017. Medical records were reviewed to identify psychiatric diagnoses before and during isotretinoin therapy, as well as psychiatric symptoms not captured by formal diagnoses and changes to isotretinoin dosing because of psychiatric diagnoses or symptoms.ResultsOne hundred seventy‐seven (29.2%) had a psychiatric diagnosis prior to isotretinoin initiation, but 98 (16.2%) had a new psychiatric diagnosis or psychiatric symptom while taking isotretinoin. Patients with a psychiatric history were no more likely than those without to receive a new psychiatric diagnosis during treatment (4.5% vs. 3.7%; p = .650), but did experience more psychiatric symptoms, primarily low mood and mood swings (23.7% vs. 7.7%; p < .001). Only 25.5% of the 98 with a new psychiatric diagnosis or psychiatric symptom had a subsequent dose change. A dose change was more likely if patients received a new psychiatric diagnosis (41.7% vs. 20.3%; p = .037) or patients did not have a psychosocial explanation for psychiatric symptoms (34.4% vs. 10.8%; p = .009).ConclusionsA substantial proportion of adolescent patients prescribed isotretinoin had a prior psychiatric diagnosis. This predicts more psychiatric symptoms during isotretinoin treatment. Adolescents with a psychiatric history who have worsening symptoms and those with new‐onset psychiatric symptoms would benefit from close monitoring while taking isotretinoin.

Importance There has been increasing concern about the burden of mental health problems among youth, especially since the COVID-19 pandemic. Trends in mental health–related emergency department (ED) visits are an important indicator of unmet outpatient mental health needs. Objective To estimate annual trends in mental health–related ED visits among US children, adolescents, and young adults between 2011 and 2020. Design, Setting, and Participants Data from 2011 to 2020 in the National Hospital Ambulatory Medical Care Survey, an annual cross-sectional national probability sample survey of EDs, was used to examine mental health–related visits for youths aged 6 to 24 years (unweighted = 49 515). Main Outcomes and Measures Mental health–related ED visits included visits associated with psychiatric or substance use disorders and were identified by International Classification of Diseases-Ninth Revision, Clinical Modification ( ICD-9-CM ; 2011-2015) and ICD-10-CM (2016-2020) discharge diagnosis codes or by reason-for-visit (RFV) codes. We estimated the annual proportion of mental health–related pediatric ED visits from 2011 to 2020. Subgroup analyses were performed by demographics and broad psychiatric diagnoses. Multivariable-adjusted logistic regression analyses estimated factors independently associated with mental health–related ED visits controlling for period effects. Results From 2011 to 2020, the weighted number of pediatric mental health–related visits increased from 4.8 million (7.7% of all pediatric ED visits) to 7.5 million (13.1% of all ED visits) with an average annual percent change of 8.0% (95% CI, 6.1%-10.1%; P &amp;lt; .001). Significant linearly increasing trends were seen among children, adolescents, and young adults, with the greatest increase among adolescents and across sex and race and ethnicity. While all types of mental health–related visits significantly increased, suicide-related visits demonstrated the greatest increase from 0.9% to 4.2% of all pediatric ED visits (average annual percent change, 23.1% [95% CI, 19.0%-27.5%]; P &amp;lt; .001). Conclusions and Relevance Over the last 10 years, the proportion of pediatric ED visits for mental health reasons has approximately doubled, including a 5-fold increase in suicide-related visits. These findings underscore an urgent need to improve crisis and emergency mental health service capacity for young people, especially for children experiencing suicidal symptoms.

Background The treatment of depression in children and adolescents is a substantial public health challenge. This study examined artificial intelligence tools for the prediction of early outcomes in depressed children and adolescents treated with fluoxetine, duloxetine, or placebo. Methods The study samples included training datasets ( N = 271) from patients with major depressive disorder (MDD) treated with fluoxetine and testing datasets from patients with MDD treated with duloxetine ( N = 255) or placebo ( N = 265). Treatment trajectories were generated using probabilistic graphical models (PGMs). Unsupervised machine learning identified specific depressive symptom profiles and related thresholds of improvement during acute treatment. Results Variation in six depressive symptoms (difficulty having fun, social withdrawal, excessive fatigue, irritability, low self‐esteem, and depressed feelings) assessed with the Children’s Depression Rating Scale‐Revised at 4–6 weeks predicted treatment outcomes with fluoxetine at 10–12 weeks with an average accuracy of 73% in the training dataset. The same six symptoms predicted 10–12 week outcomes at 4–6 weeks in (a) duloxetine testing datasets with an average accuracy of 76% and (b) placebo‐treated patients with accuracies of 67%. In placebo‐treated patients, the accuracies of predicting response and remission were similar to antidepressants. Accuracies for predicting nonresponse to placebo treatment were significantly lower than antidepressants. Conclusions PGMs provided clinically meaningful predictions in samples of depressed children and adolescents treated with fluoxetine or duloxetine. Future work should augment PGMs with biological data for refined predictions to guide the selection of pharmacological and psychotherapeutic treatment in children and adolescents with depression.

Objectives: Prior studies demonstrate elevated cortical glutamate (Glu) in patients with bipolar disorder (BD). Studies assessing neurochemistry in early stages of bipolar illness before the emergence of manic symptoms are lacking. This study aimed to examine neurochemical correlates measured by proton magnetic resonance spectroscopy ( 1 H-MRS) and a dimensional measure of bipolarity in a sample of depressed adolescents. Methods: Adolescent participants (aged 13–21 years) underwent a semistructured diagnostic interview and clinical assessment, which included the General Behavior Inventory Parent Version (P-GBI), a 73-item, parent-rated assessment of symptoms and behaviors. 1 H-MRS scans of a left dorsolateral prefrontal cortex (L-DLPFC) voxel (8 cm 3 ) were collected using a two-dimensional J -averaged sequence to assess N -acetylaspartate (NAA), Glu, Glx (glutamate + glutamine), and NAA/Glx concentrations. We used generalized linear models to assess the relationships between P-GBI scores and metabolite levels in L-DLPFC. Results: Thirty-six participants (17 healthy controls, 19 depressed) underwent 1 H-MRS scans and clinical evaluation with the P-GBI. There was a significant negative relationship between P-GBI score and L-DLPFC NAA/Glx in the whole sample. However, the magnitude of the effect was small and statistical significance was lost after correcting for multiple comparisons. Conclusions: These preliminary results suggest that NAA/Glx may have utility as a marker of bipolar traits in healthy and depressed adolescents. If replicated, 1 H-MRS measures of glutamatergic metabolism anomalies might have a role in identifying depressed adolescents at risk for mixed symptom presentations or BD. Identifying bipolarity in the early stages of the disease would have a significant impact on treatment planning and prognosis. Further longitudinal studies should examine neurochemical correlates of mood state during the developmental emergence of BD.
