Examining the association between prenatal cannabis exposure and child autism traits: A multi-cohort investigation in the environmental influences on child health outcome program.

This study examined the association between prenatal cannabis exposure and autism spectrum disorder (ASD) diagnoses and traits. A total sample of 11,570 children (ages 1-18; 53% male; 25% Hispanic; 60% White) from 34 cohorts of the National Institutes of Health-funded environmental influences on child health outcomes consortium were included in analyses. Results from generalized linear mixed models replicated previous studies showing that associations between prenatal cannabis exposure and ASD traits in children are not significant when controlling for relevant covariates, particularly tobacco exposure. Child biological sex did not moderate the association between prenatal cannabis exposure and ASD. In a large sample and measuring ASD traits continuously, there was no evidence that prenatal cannabis exposure increases the risk for ASD. This work helps to clarify previous mixed findings by addressing concerns about statistical power and ASD measurement.

Factors Associated with Resilience in Families of Children with Autism Spectrum Disorder.

OBJECTIVES: Families of children with autism spectrum disorder (ASD) report high levels of stress and poor psychological functioning. Resilience serves to buffer these challenges. Little is known about the factors associated with resilience in these families. METHODS: Data from the National Survey of Children's Health (NSCH) 2016 were used to investigate independent child, parent, and health care factors associated with resilience in families of children with ASD. We used the NSCH's family resilience composite derived from 4 survey questions focused on (1) communication, (2) working together to solve problems, (3) drawing on strengths, and (4) staying hopeful during difficult times. We defined family resilience as high or low based on the number of questions answered "all of the time" or "most of the time" versus "some of the time" or "none," respectively. Using survey weights, univariate and multivariate logistic regression analyses identified associations of child, parent, and health care factors with low family resilience. RESULTS: We analyzed data representing 1151 children with ASD. Low resilience was reported in 32% of families. Low family resilience was significantly associated with parent factors such as not having someone to turn to for support, cutting work hours, and feeling "child hard to care for"; child ASD-related factors such as moderate ASD severity; and health care factors such as lack of satisfaction in communications with providers. CONCLUSION: The findings highlight specific vulnerabilities in families of children with ASD that are associated with low family resilience. Intervention approaches that have the ability to improve overall family resilience should be carefully considered.

Acute Hematogenous Osteomyelitis in a Five-Month-Old Male with Rickets.

Osteomyelitis is defined as an infection of the bone, bone marrow, and the surrounding soft tissues. Most cases of acute hematogenous osteomyelitis in children are caused by Gram-positive bacteria, principally Staphylococcus aureus. We present a case where a 5-month-old male had an acute onset of decreased movement of his left leg and increased irritability and was subsequently diagnosed with rickets and hematogenous osteomyelitis with bacteremia. The case explores a possible association between hematogenous osteomyelitis and rickets.

Attenuated psychotic and basic symptom characteristics in adolescents with ultra-high risk criteria for psychosis, other non-psychotic psychiatric disorders and early-onset psychosis.

While attenuated psychotic symptoms (APS) and basic symptoms (BS) are the main current predictors of psychosis in adults, studies in adolescents are scarce. Thus, we (1) described the prevalence and severity of positive, negative, disorganization, general, and basic symptoms in adolescent patients at ultra-high risk for psychosis (UHR), with other non-psychotic psychiatric disorders (PC) and with early-onset psychosis (EOP); and (2) investigated BS criteria in relation to UHR criteria. Sixty-nine 12-18-year-old adolescents (15.3 ± 1.7 years, female = 58.0 %, UHR = 22, PC = 27, EOP = 20) were assessed with the structured interview for prodromal syndromes (SIPS) and the schizophrenia proneness instrument-child and youth version (SPI-CY). Despite similar current and past 12-month global functioning, both UHR and EOP had significantly higher SIPS total and subscale scores compared to PC, with moderate-large effect sizes. Expectedly, UHR had significantly lower SIPS positive symptom scores than EOP, but similar SIPS negative, disorganized, and general symptom scores. Compared to PC, both EOP and UHR had more severe basic thought and perception disturbances, and significantly more often met cognitive disturbances criteria (EOP = 50.0 %, UHR = 40.9 %, PC = 14.8 %). Compared to UHR, both EOP and PC significantly less often met cognitive-perceptive BS criteria (EOP = 35.0 %, UHR = 68.2 %, PC = 25.9 %). BS were significantly more prevalent in both EOP and UHR than PC, and UHR were similar to EOP in symptom domains. Given the uncertain outcome of adolescents at clinical high-risk of psychosis, future research is needed to determine whether the combined assessment of early subjective disturbances with observable APS can improve the accuracy of psychosis prediction.

Frequency and correlates of DSM-5 attenuated psychosis syndrome in a sample of adolescent inpatients with nonpsychotic psychiatric disorders.

OBJECTIVES: DSM-5 conceptualized attenuated psychosis syndrome (APS) as self-contained rather than as a risk syndrome, including it under "Conditions for Further Study," but also as a codable/billable condition in the main section. Since many major mental disorders emerge during adolescence, we assessed the frequency and characteristics of APS in adolescent psychiatric inpatients. METHODS: Consecutively recruited adolescents hospitalized for nonpsychotic disorders (September 2009-May 2013) were divided into APS youth versus non-APS youth, based on the Structured Interview of Prodromal Syndromes (SIPS) and according to DSM-5 criteria, and compared across multiple characteristics. RESULTS: Of 89 adolescents (mean ± SD age = 15.1 ± 1.6 years), 21 (23.6%) had APS. Compared to non-APS, APS was associated with more comorbid disorders (2.7 ± 1.0 vs 2.2 ± 1.3), major depressive disorder (61.9% vs 27.9%), oppositional defiant disorder/conduct disorder (52.4% vs 25.0%), and personality disorder traits (57.1% vs 7.4%, the only diagnostic category surviving Bonferroni correction). APS youth were more severely ill, having higher SIPS total positive, negative, and general symptoms; Brief Psychiatric Rating Scale total and positive scores; depression and global illness ratings; and lower Global Assessment of Functioning (GAF). Conversely, Young Mania Rating Scale scores, suicidal behavior, prescribed psychotropic medications, and mental disorder awareness were similar between APS and non-APS groups. In multivariable analysis, lowest GAF score in the past year (odds ratio [OR] = 51.15; 95% confidence interval [CI], 2.46-2,439.0) and social isolation (OR = 27.52; 95% CI, 3.36-313.87) were independently associated with APS (r(2) = 0.302, P < .0001). Although psychotic disorders were excluded, 65.2% (APS = 57.1%, non-APS = 67.7%, P = .38) received antipsychotics. CONCLUSION: One in 4 nonpsychotic adolescent inpatients met DSM-5 criteria for APS. APS youth were more impaired, showing a complex entanglement with a broad range of psychiatric symptoms and disorders, including depression, impulse-control, and, especially, emerging personality disorders.

Outcome of Youth with Early-Phase Schizophrenia-Spectrum Disorders and Psychosis Not Otherwise Specified Treated with Second-Generation Antipsychotics: 12 Week Results from a Prospective, Naturalistic Cohort Study.

OBJECTIVES: The purpose of this study was to assess differences in the outcomes of youth with schizophrenia-spectrum disorders (SCZ-S) and psychotic disorder not otherwise specified (PsyNOS) during early antipsychotic treatment. METHODS: The study was a prospective, naturalistic, inception cohort study of youth ≤19 years old with SCZ-S (schizophrenia, schizoaffective disorder, schizophreniform disorder) or PsyNOS (PsyNOS, brief psychotic disorder) and ≤24 months of lifetime antipsychotic treatment receiving clinician's choice antipsychotic treatment. Baseline demographic, illness and treatment variables, and effectiveness outcomes were compared at 12 weeks last-observation-carried-forward across SCZ-S and PsyNOS patients, adjusting for significantly different baseline variables. RESULTS: Altogether, 130 youth with SCZ-S (n=42) or PsyNOS (n=88), mostly antipsychotic naïve (76.9%), were prescribed risperidone (47.7%), olanzapine (19.2%), aripiprazole (14.6%), quetiapine (11.5%), or ziprasidone (6.9%). Compared with those with PsyNOS, SCZ-S youth were older (16.4±2.1 vs. 14.8±3.2, p=0.0040), and less likely to be Caucasian (19.1% vs. 42.5%, p=0.009). At baseline, SCZ-S patients had significantly higher Clinical Global Impressions-Severity (CGI-S) scores (6.0±0.9 vs. 5.5±0.8, p=0.0018) and lower Children's Global Assessment Scale (CGAS) scores (29.6±9.2 vs. 36.1±8.9, p=0.0002) and were more likely to be in the severely ill CGAS group (i.e., CGAS≤40). SCZ-S and PsyNOS patients did not differ regarding all-cause discontinuation (40.5 vs. 40.3%. p=0.49), discontinuation because of adverse effects (12.2% vs. 12.4%, p=0.97), or nonadherence (29.3% vs. 30.9%, p=0.88), but somewhat more SCZ-S patients discontinued treatment for inefficacy (19.5% vs. 7.4%, p=0.063). CGI-S and CGAS scores improved significantly in both diagnostic groups (p=0.0001, each). Adjusting for baseline differences, PsyNOS patients experienced significantly better CGI-I improvement (CGI-I) scores (p=0.012) and more frequently reached higher categorical CGAS group status (p=0.021) than SCZ-S patients. CONCLUSIONS: Both youth with SCZ-S and those with PsyNOS experienced significant improvements with clinician's choice antipsychotic treatment. However, treatment discontinuation was common within 12 weeks, with greater inefficacy-related discontinuation in the SCZ-S group, whereas CGI-I and CGAS score-based improvements were greater in the PsyNOS group.

Neuromotor Adverse Effects in 342 Youth During 12 Weeks of Naturalistic Treatment With 5 Second-Generation Antipsychotics.

OBJECTIVE: Second-generation antipsychotic (SGA) effects in youth were monitored to quantify extrapyramidal side effects (EPS) and to identify risk profiles for treatment-emergent EPS. METHOD: Data were analyzed for the nonrandomized, prospective Second-generation Antipsychotic Treatment Indications, Effectiveness and Tolerability in Youth (SATIETY) inception cohort study. EPS were assessed at baseline and 4, 8, and 12 weeks after naturalistic SGA initiation for schizophrenia, mood, disruptive behavior, and autism spectrum disorders using the Simpson-Angus Scale (SAS), Barnes Akathisia Scale, Abnormal Involuntary Movement Scale (AIMS), and Treatment Emergent Side Effect Scale. Drug-induced parkinsonism was defined by incident mean SAS score >0.33, anticholinergic initiation, or increasing total SAS score ≥2 in patients with baseline EPS. RESULTS: In 342 youth aged 13.6 ± 3.5 years (male = 58.2%, antipsychotic-naive = 65.8%), 15.2% developed drug-induced parkinsonism. Raw SGA-grouped drug-induced parkinsonism rates were as follows: quetiapine = 1.5%, olanzapine = 13.8%, risperidone = 16.1%, ziprasidone = 20.0%, and aripiprazole = 27.3%. SGA type, dose, higher age, and lower baseline functioning were jointly associated with drug-induced parkinsonism (R(2) = 0.18; p < .0001). Controlling for these factors, drug-induced parkinsonism rates were significantly lower only for quetiapine and olanzapine. Subjectively reported EPS (5%), EPS-related treatment discontinuation (3.3%), and anticholinergic initiation (3%) were infrequent. Anticholinergic initiation was most frequent with risperidone (10.2%; p = .0004). Treatment-emergent dyskinesia ranged from 4.5% (aripiprazole) to 15.5% (olanzapine). SGA type, younger age, white race/ethnicity, and baseline AIMS were jointly associated with treatment-emergent dyskinesia (R(2) = 0.31; p < .0001). Controlling for these factors, treatment-emergent dyskinesia rates differed among SGA subgroups, with higher rates with olanzapine and ziprasidone. At baseline, psychostimulant use was associated with dyskinesia, and number of psychotropic comedications was associated with subjective EPS. CONCLUSION: In youth, SGA-related EPS rates did not generally exceed those reported in adults, with particularly low rates with quetiapine and olanzapine.

Early nonresponse determined by the clinical global impressions scale predicts poorer outcomes in youth with schizophrenia spectrum disorders naturalistically treated with second-generation antipsychotics.

OBJECTIVE: The use of early response/nonresponse (ER/ENR) to antipsychotics as a predictor for ultimate response/nonresponse (UR/UNR) may help decrease inefficacious treatment continuation. However, data have been limited to adults, and ER/ENR has only been determined using time-consuming psychopathology rating scales. In the current study, we assessed if early improvement on the Clinical Global Impressions-Improvement (CGI-I) scale predicted UR/UNR in psychiatrically ill youth started on antipsychotic treatment. METHODS: Seventy-nine youth aged 6-19 years, with schizophrenia spectrum disorders, treated naturalistically with aripiprazole, olanzapine, quetiapine, risperidone, or ziprasidone and evaluated monthly, were divided into ER/ENR groups at week 4, using at least "minimally improved" on the CGI-I scale. Prediction using week 4 ER/ENR status for UR (CGI-I=at least "much improved"), effectiveness and adverse effect outcomes at 8-12 weeks were assessed. RESULTS: At 4 weeks, 45.6% of subjects were ER and 54.4% were ENR without differences regarding baseline demographic, illness, and treatment variables, except for higher age (p=0.034) and maximum risperidone dose (p=0.0043) in ENR. ER/ENR status at 4 weeks predicted UR/UNR at week 12 significantly (p<0.0001): Sensitivity=68.9%, specificity=85.3%, positive predictive value=86.1%, negative predictive value=67.4%. At weeks 4, 8, and 12, ER patients improved significantly more on the CGI-I, CGI-Severity, and Children's Global Assessment of Functioning scales, and more ER patients reached UR compared with ENR patients (83.3% vs. 34.9%, all p<0.0001). ENR patients had more extrapyramidal side effects (EPS) at weeks 4, 8, and 12 (p=0.0019-0.0079). UR was independently associated with ER (odds ratio [OR]=18.09; 95% confidence interval [CI]=4.71-91.68, p<0.0001) and psychosis not otherwise specified (NOS) (OR=4.82 [CI: 1.31-21.41], p=0.017) (r(2)=0.273, p<0.0001). CONCLUSIONS: Older age and EPS were associated with ENR; ENR and schizophrenia were associated with UNR in naturalistically treated youth with schizophrenia spectrum disorders. Early CGI-I-based treatment decisions require further consideration and study.
