OBJECTIVES/OBJECTIVE:Access to firearms is an independent risk factor for completed suicide and homicide, and the American Academy of Pediatrics recommends that pediatricians screen and counsel about firearm access and safe storage. This study investigates how often pediatric residents screen for access to firearms or counsel about risk-reduction in patients with suicidal or homicidal ideation. METHODS:Retrospective chart review of visits by patients under the age of 19 years presenting to the pediatric emergency department (ED) of a tertiary academic medical center January-December 2016. Visits were eligible if there was an ultimate ED discharge diagnosis of "suicidal ideation," "suicide attempt," or "homicidal ideation" as identified by ICD-10 codes and the patient was seen by a pediatric resident prior to evaluation by psychiatry. Descriptive statistics were used to analyze results. RESULTS:Ninety-eight patients were evaluated by a pediatric resident for medical assessment before evaluation by a psychiatry team during the study period and were therefore eligible for inclusion. Screening for firearm access was documented by a pediatric resident in 5/98 (5.1%) patient encounters. Twenty-five patients (25.5%) had no documented screening for firearm access by any provider during the ED visit, including in five cases when patients were discharged home. CONCLUSIONS:Pediatric residents rarely document screening for firearm access in patients with known suicidal or homicidal ideation who present to the ED. Additional understanding of the barriers to screening and potential strategies for improving screening and counseling are critical to providing appropriate care for high-risk pediatric patients.

BACKGROUND:Alcohol use disorder (AUD) is a wide-spread, heritable brain disease, but few studies have linked genetic variants or epigenetic factors to brain structures related to AUD in humans, due to many factors including the high-dimensional nature of imaging and genomic data. METHODS:To provide potential insights into the links among epigenetic regulation, brain structure, and AUD, we have performed an integrative analysis of brain structural imaging and blood DNA methylome data from 52 AUD and 58 healthy control (HC) subjects collected in the Nathan Kline Institute-Rockland Sample. RESULTS:We first found that AUD subjects had significantly larger insular surface area than HC in both left and right hemispheres. We then found that 7,827 DNA methylation probes on the HumanMethylation450K BeadChip had significant correlations with the right insular surface area (false discovery rate [FDR] < 0.05). Furthermore, we showed that 44 of the insular surface area-correlated methylation probes were also strongly correlated with AUD status (FDR < 0.05). These AUD-correlated probes are annotated to 36 protein-coding genes, with 16 genes (44%) having been reported by others to be related to AUD or alcohol response, including TAS2R16 and PER2. The remaining 20 genes, in particular ARHGAP22, might represent novel genes involved in AUD or responsive to alcohol. CONCLUSIONS:We have identified 36 insular surface area- and AUD-correlated protein-coding genes that are either known to be AUD- or alcohol-related or not yet reported by prior studies. Therefore, our study suggests that the brain imaging-guided epigenetic analysis has a potential of identifying possible epigenetic mechanisms involved in AUD.

Maggie is a 16-year-old girl who came to see me because she wanted help with her longstanding difficulties falling asleep at night and waking up in the morning. She goes to bed between midnight and 3 am and usually lies awake worrying until falling asleep at 3 to 4 am. She often video-calls or texts her boyfriend before sleep. Her wakeup time is 8 am; she typically wakes exhausted, having slept 4 to 5 hours. Although a good student, she is often late for classes. On weekends, she wakes around noon. She is tired, anxious, and demoralized. She cannot concentrate as well as she did prior to the onset of her sleep symptoms at age 10 to 11 years. Her psychiatric history includes a diagnosis of anxiety and depression, both in remission, treated with fluoxetine 30 mg daily for several years. Difficulties falling asleep and waking in the morning are common complaints among adolescents and young adults. Before my additional year of training in sleep medicine, I would have misdiagnosed Maggie as having insomnia rather than delayed sleep phase disorder (DSPD), a circadian rhythm disorder.

In traditional medical practice, the diagnostic interview is focused on symptom collection, diagnosis, and treatment. The psychiatric interview is based on the medical model, but mental health clinicians lack the tests found in general medicine. Rapport is the most essential tool for the psychiatrist to uncover symptoms and develop a diagnosis and treatment plan. This article brings a scientific lens to the psychiatric interview. Under this microscope the value of eliciting the patient's well-being at the outset of the interview becomes clear. Using positive psychology, an evidenced-based rationale for the positive assessment is outlined and methodology and practice of the assessment reviewed.

OBJECTIVE:/UNASSIGNED:ALPIM (anxiety, laxity, pain, immune, and mood) syndrome has been previously described in adults. The authors aimed to identify its occurrence in adolescents and confirm its existence in adults. Given the association of the disorder with somatic symptoms, separation anxiety disorder (SAD) was explored as an ALPIM comorbidity. METHODS:/UNASSIGNED:Medical records of patients aged 11-34 with a diagnosis of depression or anxiety (panic disorder, SAD, social anxiety or generalized anxiety disorder) seen during a 1-year period were reviewed. Data were collected on the presence of ALPIM comorbidities. Analyses were conducted to detect their co-occurrence and evaluate possible predictors of the ALPIM syndrome. RESULTS:/UNASSIGNED:Inclusion criteria were met by 185 patient charts. A significant association was observed between the ALPIM comorbidities with 20 study subjects (10.8%) meeting criteria for ALPIM syndrome (patients with one or more diagnoses from each ALPIM domain). Patients with SAD had increased odds of being diagnosed with ALPIM (odds ratio=7.14, 95% CI=2.48-20.54, p<0.001). Neither major depression nor generalized anxiety disorder was found to be predictive of ALPIM syndrome. There was no difference in the prevalence of ALPIM-related comorbidities between study subjects <18 years old compared with those ≥18 years old. CONCLUSIONS:/UNASSIGNED:These findings reestablish the association of distinct psychiatric and nonpsychiatric conditions described as the ALPIM syndrome. Furthermore, the syndrome may present during adolescence. SAD may be an independent predictive factor for the occurrence of ALPIM syndrome. Patients with individual ALPIM comorbidities should be assessed for the syndrome, especially if they have a history of SAD.

Autism spectrum disorder is characterized by difficulties with social communication, with a preponderance in males. Evidence supports a relationship between metacognitive executive functions (e.g. planning, working memory) and social communication in autism spectrum disorder, yet relationships with specific metacognitive executive functions and how gender alters the expression of these relationships require further study. We used multiple regression to examine relationships between informant-based measures of metacognitive executive function and social communication in intellectually able (IQ ⩾ 85) female ( n = 111; mean age = 10.2 ± 2.8; 31 autism spectrum disorder) and male youth ( n = 310; mean age = 10.5 ± 1.9; 146 autism spectrum disorder) with and without autism spectrum disorder from the Autism Brain Imaging Data Exchange-II database. Executive function-social communication relationships were different in females and males with autism spectrum disorder. Relationships between the entire metacognitive index and social communication were stronger in males with autism spectrum disorder than without; this pattern was also observed for metacognitive sub-indices 'monitor' and 'working memory'. These patterns were not observed in females. Relationships between executive function and social communication appear different for female and male youth with an autism spectrum disorder diagnosis. To better understand the nature of metacognitive contributions to social communication in autism spectrum disorder, future work should investigate the co-development of monitoring, working memory and social communication, while taking gender into account.

The aim of this study was to conduct a systematic review of the literature and meta-analysis to estimate the association between psychophysiological activity and reactivity at baseline or after a psychological task with CP among children and adolescents. We systematically reviewed published studies reporting autonomic nervous system activity in youth with CP and meta-analyzed the relationship between CP and autonomic baseline as well as task-related reactivity in 66 studies (N = 10,227). Across 34 included case-control studies that were based on CP cut-off scores, we found a significant pooled effect for task related Skin-Conductance, Respiratory Sinus Arrhythmia, and cardiac Pre-Ejection Period, but no significant group differences for Heart Rate nor for any baseline measures. Findings suggested reduced parasympathetic and sympathetic reactivity to emotional tasks, pointing to co-inhibition of the two systems. However, across 32 studies with correlational design we only found a significant negative correlation of baseline and task-related heart rate with CP. The present meta-analysis derived several conclusions that have the potential to inform biological vulnerability models and biologically driven interventions.

BACKGROUND:Attention-deficit/hyperactivity disorder (ADHD) often emerges during the preschool years and remains impairing throughout the life span. Early identification and intervention may yield lasting benefits that alter the often-adverse trajectory of the disorder. METHODS:This Practitioner Review provides up-to-date information regarding the evaluation and treatment of ADHD in preschool children. The clinical presentation of ADHD in preschool children, its persistence into later childhood, the applicability of DSM-5 criteria for preschoolers with ADHD, and early predictors of long-term trajectories are addressed, as well as current findings from randomized controlled trials of both nonpharmacological and pharmacological interventions. RESULTS:Symptoms of hyperactivity/impulsivity extend down to age 3, but several inattention symptoms, as defined by DSM-V, less accurately differentiate preschoolers with and without ADHD. Most preschool youth with ADHD symptoms continue to manifest symptoms and impairment into school-age and adolescence. However, few predictors of persistence beyond early severity have been identified. Behavioral interventions constitute a first-line treatment for preschool ADHD symptoms, with telepsychiatry increasing in prominence to help to mitigate financial, geographic, and/or logistical barriers to care. Pharmacological interventions, particularly psychostimulants, also confer demonstrable benefits, yet efficacy and safety profiles are less desirable relative to findings in school-age youth. CONCLUSIONS:Acute treatments have demonstrable efficacy, but do not appear to fundamentally alter underlying mechanisms or long-term trajectories.
