Severity of Antipsychotic-Induced Cervical Dystonia Assessed by the Algorithm-Based Rating System.

Background: The severity of antipsychotic-induced cervical dystonia has traditionally been evaluated visually. However, recent advances in information technology made quantification possible in this field through the introduction of engineering methodologies like machine learning.Methods: This study was conducted from June 2021 to March 2023. Psychiatrists rated the severity of cervical dystonia into 4 levels (0: none, 1: minimal, 2: mild, and 3: moderate) for 101 videoclips, recorded from 87 psychiatric patients receiving antipsychotics. The Face Mesh function of the open-source framework MediaPipe was employed to calculate the tilt angles of anterocollis or retrocollis, laterocollis, and torticollis. These were calculated to examine the range of tilt angles for the 4 levels of severity of the different types of cervical dystonia.Results: The tilt angles calculated using Face Mesh for each level of dystonia were 0° ≤ θ < 6° for none, 6° ≤ θ < 11° for minimal, 11° ≤ θ < 25° for mild, and 25° ≤ θ for moderate laterocollis; 0° ≤ θ < 11° for none, 11° ≤ θ < 18° for minimal, 18° ≤ θ <25° for mild, and 25° ≤ θ for moderate anterocollis or retrocollis; and 0° ≤ θ < 9° for none, 9° ≤ θ < 17° for minimal, 17° ≤ θ < 32° for mild, and 32° ≤ θ for moderate torticollis.Conclusion: While further validation with new cases is needed, the range of tilt angles in this study could provide a standard for future artificial intelligence devices for cervical dystonia.

Clozapine Treatment for Aggressive Behaviors in Youths with Neurodevelopmental Disorders.

Objectives: The aim of this study was to assess effectiveness and tolerability of Clozapine in the treatment of aggression in youth with Neurodevelopmental Disorders. Methods: Patients were consecutively admitted at our third-level university hospital with nationwide catchment from June 2018 to October 2022, and followed up to July 2023. Eligibility criteria were as follows: (1) Autism Spectrum Disorder (ASD) and/or Intellectual Disability/Borderline Cognitive Functioning, (2) behavioral dyscontrol with physical aggression; (3) age range between 8 and 18 years; (4) clinical indication for Clozapine treatment after at least two failed trials with other Second-Generation Antipsychotics (SGAs); (5) availability of an at least 6-month-long follow-up. To evaluate the response to Clozapine, we used the Clinical Global Impressions (CGI) rating scales (Clinical Global Impressions-Severity [CGI-S] and Clinical Global Impressions-Improvement [CGI-I]), the Children's Global Assessment Scale (CGAS), and the Aberrant Behavior Checklist (ABC). Results: Twenty-six children and adolescents (21 boys, age 13.47 ± 2.05 years, follow-up duration 9.77 ± 3.50 months) were included in the analysis. Clinical severity (CGI-S) and functional impairment (Clinical Global Assessment Scale) significantly improved, as well as the ABC Total Score and the scores in several subscales. Sixteen patients (61.54%) were responders (CGI-I ≤2), and 13 (50.00%) displayed remission of aberrant behaviors (ΔABC-Total >35), while response/remission condition was not affected by add-on medications and psychotherapy. Most frequent side effects were increased appetite (50.00%), sialorrhea (38.46%), and increased repetitive behaviors (26.92%). Two patients presented epileptic seizures, while no patients presented leucopoenia. Conclusions: Our results suggest that Clozapine may be helpful in ameliorating treatment-resistant aggression in youth with neurodevelopmental conditions. Possible pharmacological strategies for the management of most frequent side effects are also suggested.

Multiple serum anti-glutamate receptor antibody levels in clozapine-treated/naïve patients with treatment-resistant schizophrenia.

BACKGROUND: Glutamatergic function abnormalities have been implicated in the etiology of treatment-resistant schizophrenia (TRS), and the efficacy of clozapine may be attributed to its impact on the glutamate system. Recently, evidence has emerged suggesting the involvement of immune processes and increased prevalence of antineuronal antibodies in TRS. This current study aimed to investigate the levels of multiple anti-glutamate receptor antibodies in TRS and explore the effects of clozapine on these antibody levels. METHODS: Enzyme linked immunosorbent assay (ELISA) was used to measure and compare the levels of anti-glutamate receptor antibodies (NMDAR, AMPAR, mGlur3, mGluR5) in clozapine-treated TRS patients (TRS-C, n = 37), clozapine-naïve TRS patients (TRS-NC, n = 39), and non-TRS patients (nTRS, n = 35). Clinical symptom severity was assessed using the Positive and Negative Symptom Scale (PANSS), while cognitive function was evaluated using the MATRICS Consensus Cognitive Battery (MCCB). RESULT: The levels of all four glutamate receptor antibodies in TRS-NC were significantly higher than those in nTRS (p < 0.001) and in TRS-C (p < 0.001), and the antibody levels in TRS-C were comparable to those in nTRS. However, no significant associations were observed between antibody levels and symptom severity or cognitive function across all three groups after FDR correction. CONCLUSION: Our findings suggest that TRS may related to increased anti-glutamate receptor antibody levels and provide further evidence that glutamatergic dysfunction and immune processes may contribute to the pathogenesis of TRS. The impact of clozapine on anti-glutamate receptor antibody levels may be a pharmacological mechanism underlying its therapeutic effects.

Neuroleptic Malignant Syndrome Concurrent with COVID-19 Infection: A Case Report. / COVID-19 Hastasinda Nöroleptik Malin Sendrom: Bir Olgu Sunumu.

Neuroleptic malignant syndrome (NMS), which most often occurs after the use of antipsychotics, is a rare but life-threatening condition. In this article, a 56-year-old male patient with a diagnosis of bipolar affective disorder (BPD) who developed NMS after a COVID-19 infection will be presented. The patient had been brought to the emergency room with high fever, fatigue, and slowness of movements that had been going on for two days. The examination revealed tachycardia, tachypnea, lethargy and rigidity. Upon further investigation the COVID-19 test came out positive and the serum levels of creatine kinase were considerably high. He was admitted to the psychiatric ward with diagnoses of COVID-19 infection and NMS. COVID-19 infection might have been a risk factor for NMS in this patient. Especially in patients who are taking antipsychotic drugs, if COVID-19 is present, the risk of NMS should be taken into consideration.

KardiaMobile 6L for measuring QT interval in people having antipsychotic medication to inform early value assessment: a systematic review.

Background: The indication for this assessment is the use of the KardiaMobile six-lead electrocardiogram device for the assessment of QT interval-based cardiac risk in service users prior to the initiation of, or for the monitoring of, antipsychotic medications, which are associated with an established risk of QT interval prolongation. Objectives: To provide an early value assessment of whether KardiaMobile six-lead has the potential to provide an effective and safe alternative to 12-lead electrocardiogram for initial assessment and monitoring of QT interval-based cardiac risk in people taking antipsychotic medications. Review methods: Twenty-seven databases were searched to April/May 2022. Review methods followed published guidelines. Where appropriate, study quality was assessed using appropriate risk of bias tools. Results were summarised by research question; accuracy/technical performance; clinical effects (on cardiac and psychiatric outcomes); service user acceptability/satisfaction; costs of KardiaMobile six-lead. Results: We did not identify any studies which provided information about the diagnostic accuracy of KardiaMobile six-lead, for the detection of corrected QT-interval prolongation, in any population. All studies which reported information about agreement between QT interval measurements (corrected and/or uncorrected) with KardiaMobile six-lead versus 12-lead electrocardiogram were conducted in non-psychiatric populations, used cardiologists and/or multiple readers to interpret electrocardiograms. Where reported or calculable, the mean difference in corrected QT interval between devices (12-lead electrocardiogram vs. KardiaMobile six-lead) was generally small (≤ 10 ms) and corrected QT interval measured using KardiaMobile six-lead was consistently lower than that measured using 12-lead electrocardiogram. All information about the use of KardiaMobile six-lead, in the context of QT interval-based cardiac risk assessment for service users who require antipsychotic medication, was taken from retrospective surveys of staff and service users who had chosen to use KardiaMobile six-lead during pilots, described in two unpublished project reports. It is important to note that both these project reports relate to pilot studies which were not intended to be used in wider evaluations of KardiaMobile six-lead for use in the NHS. Both reports included survey results which indicated that the use of KardiaMobile six-lead may be associated with reductions in the time taken to complete an electrocardiogram and costs, relative to 12-lead electrocardiogram, and that KardiaMobile six-lead was preferred over 12-lead electrocardiogram by almost all responding staff and service users. Limitations: There was a lack of published evidence about the efficacy of KardiaMobile six-lead for initial assessment and monitoring of QT interval-based cardiac risk in people taking antipsychotic medications. Conclusions: There is insufficient evidence to support a full diagnostic assessment evaluating the clinical and cost effectiveness of KardiaMobile six-lead, in the context of QT interval-based cardiac risk assessment for service users who require antipsychotic medication. The evidence to inform the aims of this early value assessment (i.e. to assess whether the device has the potential to be clinically effective and cost-effective) was also limited. This report includes a comprehensive list of research recommendations, both to reduce the uncertainty around this early value assessment and to provide the additional data needed to inform a full diagnostic assessment, including cost-effectiveness modelling.

Some medicines used for people with certain mental health problems can increase the risk of developing serious heart conditions. Although these heart conditions are rare, it is generally recommended that people have an electrocardiogram examination before starting to take these medicines. People who need to continue these medications over a period of time may need additional electrocardiograms every so often, to check for any heart problems that have developed recently. KardiaMobile six-lead (or 6-lead) is a portable electrocardiogram that may offer a less intrusive way to take electrocardiogram measurements. This is because less undressing is needed as the electrodes are only applied to fingers of the left and right hand and the left ankle or knee and the cold gel is not needed. Testing using the KardiaMobile six-lead device can be carried out at the patient's home. These features might mean that the KardiaMobile six-lead device could be more acceptable than the 12-lead electrocardiogram to some patients. This assessment considered whether the KardiaMobile six-lead device has the potential to provide an effective and safe alternative to 12-lead electrocardiogram for initial assessment and monitoring of the risk of heart problems in people taking antipsychotic medications. Based on the available evidence, it remains unclear whether KardiaMobile six-lead has adequately demonstrated sufficient evidence of potential advantage(s) over current practice to justify further research to inform assessment of its clinical effectiveness and cost effectiveness. Our report provides detailed recommendations about the research needed, to provide further information about potential benefits so that a decision can be made about whether it should be used in the NHS in England, after further research has been completed.

Safety Profile of Pimavanserin Therapy in Elderly Patients with Neurodegenerative Disease-Related Neuropsychiatric Symptoms: A Phase 3B Study.

Background: Pimavanserin, a 5-HT2A receptor inverse agonist/antagonist, is the only medication approved by the FDA for the treatment of hallucinations and delusions associated with Parkinson's disease psychosis (PDP). Further expanding knowledge of the safety profile of pimavanserin in PDP and neurodegenerative diseases (NDD) such as Alzheimer's disease is of great interest for informing its use in patients with PDP (with or without dementia), given this population is highly sensitive to adverse effects following antipsychotic use. Objective: This trial evaluated the effects of pimavanserin compared to placebo in frail older adults and elderly patients with neuropsychiatric symptoms related to NDD, such as hallucinations and delusions, to better understand the safety of pimavanserin in this population. Methods: This was a phase 3b, 8-week treatment (study duration of up to 16 weeks), multicenter, randomized, double-blind, placebo-controlled, two-arm parallel-group trial (NCT03575052). The primary endpoint was safety and tolerability, measured by treatment-emergent adverse events (TEAEs). Secondary safety endpoints were change from baseline in motor and cognitive function; exploratory endpoints included suicidality, sleep quality, and neuropsychiatric symptoms. Results: Incidences of TEAEs were similar between treatment groups; 29.8% reported ≥1 TEAE (pimavanserin: 30.4%; placebo: 29.3%), and 1.8% reported serious TEAEs (pimavanserin: 2.0%; placebo: 1.5%). Pimavanserin did not impact motor- or cognitive-related function. Conclusions: Pimavanserin was well tolerated and not associated with motor or cognitive impairment. Together, these findings highlight the manageable and generally favorable safety profile of pimavanserin in patients with NDD, contributing to our knowledge on the safety of pimavanserin as it generalizes to patients with PDP.

Association between prenatal antipsychotic exposure and the risk of attention-deficit/hyperactivity disorder and autism spectrum disorder: a systematic review and meta-analysis.

The paucity of evidence regarding the safety of gestational antipsychotic exposure has led to treatment discontinuation in pregnant women with severe mental health conditions. This systematic review and meta-analysis aimed to summarise the current evidence on the association between gestational antipsychotic exposure and attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in children (Study protocol registered in PROSPERO:CRD42022311354). Five studies included in our meta-analysis with around 8.6 million pregnancy episodes in nine different countries/regions. Results from our meta-analysis indicate that the heightened risks of ASD and ADHD in children gestationally exposed to antipsychotics appear to be attributable to maternal characteristics, rather than having a causal relationship with the antipsychotic exposure during pregnancy. The results underscore the importance of meticulously monitoring the neurodevelopment of children born to mothers with mental illnesses, which can facilitate early interventions and provide requisite support.

Aripiprazol: cuidado con la adicción patológica al juego / Aripiprazole: Beware of pathological gambling addiction

El aripiprazol es un medicamento antipsicótico utilizado en el tratamiento de diversas enfermedades psiquiátricas. Entre sus diferentes efectos adversos destaca uno muy infrecuente, pero grave. El desarrollo de comportamientos adictivos como el juego patológico es una situación que puede llevar a consecuencias negativas en la vida personal, social y financiera de los pacientes. Se presenta un caso sobre el aripiprazol y el juego patológico para destacar este efecto poco común. (AU)

Aripiprazole is an antipsychotic drug used in the treatment of various psychiatric illnesses. Among its various adverse effects, one very rare but serious one stands out. The development of addictive behaviours such as pathological gambling is a situation that can lead to negative consequences in the personal, social and financial life of patients. A case on aripiprazole and pathological gambling is presented to highlight this rare effect. (AU)

Clozapine-induced pneumonitis mimicking an atypical pneumonia.

Clozapine is an antipsychotic used for treatment-resistant schizophrenia with a significant side effect profile, including agranulocytosis, myocarditis and fever. Clozapine-induced fever often occurs in the first 2 weeks of treatment and settle after a few days. We report a case of a woman in her mid-30s who developed fever and infective symptoms suggestive of an atypical pneumonia while on clozapine titration. She was on clozapine for 16 days before developing high-grade fever, dry cough, diarrhoea, headache and photophobia with a very high CRP. We performed an extensive infection workup that returned negative results except for bilateral upper lobe ground glass changes of the lungs on CT. Despite antibiotic therapy, which would cover an atypical pneumonia, her CRP remained elevated and her fever persisted. Focus was directed to clozapine-induced pneumonitis as the cause for her symptoms. Her antibiotics were ceased, and clozapine was downtitrated. With the adjustment of her clozapine dose, her fevers and associated symptoms resolved, and CRP downtrended. Her fevers did not return when clozapine was uptitrated in the community subsequently. Clozapine-induced fever or other immune-allergic reactions should be systematically considered when patients develop fever during the initiation phase of clozapine therapy. Ruling out infective causes is desirable prior to attributing fevers to clozapine especially when they are accompanied by infective symptoms and high inflammatory markers. Careful downtitration of clozapine should be considered rather than abrupt cessation in managing clozapine-induced fevers and subsequent slow uptitration could be considered.

Pregabalin Adjuventia Helped Risperidone-Induced Extrapyramidal Syndrome and Augmented Antipsychotic Response in an Adolescent with Schizophrenia.

Here, authors report on an interesting case of early-onset of schizophrenia where adjunctive pregabalin alleviated risperidone-induced pseudoparkinsonism, helped with insomnia and agitation and boosted antipsychotic response with great tolerability. We wager that gabapentenoids can be a viable option in the niche of psychopharmacotherapy of schizophrenia in CAP population.

Drug Efficacy in the Treatment of Antipsychotic-Induced Akathisia: A Systematic Review and Network Meta-Analysis.

Importance: Antipsychotic-induced akathisia (AIA) occurs in 14% to 35% of patients treated with antipsychotics and is associated with increased suicide and decreased adherence in patients with schizophrenia. However, no comprehensive review and network meta-analysis has been conducted to compare the efficacy of treatments for AIA. Objective: To compare the efficacy associated with AIA treatments. Data Sources: Three databases (MEDLINE, Web of Science, and Google Scholar) were systematically searched by multiple researchers for double-blind randomized clinical trials (RCTs) comparing active drugs for the treatment of AIA with placebo or another treatment between May 30 and June 18, 2023. Study Selection: Selected studies were RCTs that compared adjunctive drugs for AIA vs placebo or adjunctive treatment in patients treated with antipsychotics fulfilling the criteria for akathisia, RCTs with sample size of 10 patients or more, only trials in which no additional drugs were administered during the study, and RCTs that used a validated akathisia score. Trials with missing data for the main outcome (akathisia score at the end points) were excluded. Data Extraction and Synthesis: Data extraction and synthesis were performed, estimating standardized mean differences (SMDs) through pairwise and network meta-analysis with a random-effects model. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed. Main Outcomes and Measures: The primary outcome was the severity of akathisia measured by a validated scale at the last available end point. Results: Fifteen trials involving 492 participants compared 10 treatments with placebo. Mirtazapine (15 mg/d for ≥5 days; SMD, -1.20; 95% CI, -1.83 to -0.58), biperiden (6 mg/d for ≥14 days; SMD, -1.01; 95% CI, -1.69 to -0.34), vitamin B6 (600-1200 mg/d for ≥5 days; SMD, -0.92; 95% CI, -1.57 to -0.26), trazodone (50 mg/d for ≥5 days; SMD, -0.84; 95% CI, -1.54 to -0.14), mianserin (15 mg/d for ≥5 days; SMD, -0.81; 95% CI, -1.44 to -0.19), and propranolol (20 mg/d for ≥6 days; SMD, -0.78; 95% CI, -1.35 to -0.22) were associated with greater efficacy than placebo, with low to moderate heterogeneity (I2 = 34.6%; 95% CI, 0.0%-71.1%). Cyproheptadine, clonazepam, zolmitriptan, and valproate did not yield significant effects. Eight trials were rated as having low risk of bias; 2, moderate risk; and 5, high risk. Sensitivity analyses generally confirmed the results for all drugs except for cyproheptadine and propranolol. No association between effect sizes and psychotic severity was found. Conclusions and Relevance: In this systematic review and network meta-analysis, mirtazapine, biperiden, and vitamin B6 were associated with the greatest efficacy for AIA, with vitamin B6 having the best efficacy and tolerance profile. Trazodone, mianserin, and propranolol appeared as effective alternatives with slightly less favorable efficacy and tolerance profiles. These findings should assist prescribers in selecting an appropriate medication for treating AIA.

A quality improvement program for managing clozapine-induced constipation in a long-term structured residential setting for persons with serious mental illness.

OBJECTIVES: The goal of this quality improvement project (QIP) was to increase awareness of the serious medical consequences of clozapine-associated constipation to front line nursing staff and patients with schizophrenia. METHODS: The QIP was developed iteratively by psychiatric nurses, psychiatrists and pharmacists with input from patients. The processes involved a literature review, development of educational materials for staff and patients, and the creation of a daily bowel movements log (BML). Implementation involved review of the BML at treatment team meetings, and deployment of pharmacological and non-pharmacological interventions to resolve constipation and increase awareness and knowledge of this clinical concern. OUTCOMES: The initial pilot screened for symptoms of constipation in patients receiving clozapine and non-clozapine antipsychotic agents and intervening as necessary during multidisciplinary team meetings. Patients benefited from relief of constipation and improved bowel habits. Staff benefited from improved knowledge and making requisite changes in workflow and practice. Feedback allowed refinements to be made to the educational materials for patients and staff. Since full implementation, bowel habits are routinely monitored, and interventions are reviewed for effectiveness. Staff satisfaction with this QIP is reflected in answers to a structured questionnaire and in patient reports (n = 50). CONCLUSIONS: Clozapine, the only approved and efficacious medication for treatment-resistant schizophrenia is significantly underutilized. Medically consequential constipation can be a serious barrier to retention of patients benefiting from clozapine. Increased awareness and use of educational materials for patients and staff, routine monitoring of bowel habits combined with pharmacological and non-pharmacological interventions can successfully address this clinical problem.

An Evidence-Based Update on Anticholinergic Use for Drug-Induced Movement Disorders.

Drug-induced movement disorders (DIMDs) are associated with use of dopamine receptor blocking agents (DRBAs), including antipsychotics. The most common forms are drug-induced parkinsonism (DIP), dystonia, akathisia, and tardive dyskinesia (TD). Although rare, neuroleptic malignant syndrome (NMS) is a potentially life-threatening consequence of DRBA exposure. Recommendations for anticholinergic use in patients with DIMDs were developed on the basis of a roundtable discussion with healthcare professionals with extensive expertise in DIMD management, along with a comprehensive literature review. The roundtable agreed that "extrapyramidal symptoms" is a non-specific term that encompasses a range of abnormal movements. As such, it contributes to a misconception that all DIMDs can be treated in the same way, potentially leading to the misuse and overprescribing of anticholinergics. DIMDs are neurobiologically and clinically distinct, with different treatment paradigms and varying levels of evidence for anticholinergic use. Whereas evidence indicates anticholinergics can be effective for DIP and dystonia, they are not recommended for TD, akathisia, or NMS; nor are they supported for preventing DIMDs except in individuals at high risk for acute dystonia. Anticholinergics may induce serious peripheral adverse effects (e.g., urinary retention) and central effects (e.g., impaired cognition), all of which can be highly concerning especially in older adults. Appropriate use of anticholinergics therefore requires careful consideration of the evidence for efficacy (e.g., supportive for DIP but not TD) and the risks for serious adverse events. If used, anticholinergic medications should be prescribed at the lowest effective dose and for limited periods of time. When discontinued, they should be tapered gradually.

A proposal for reducing maximum target doses of drugs for psychosis: Reviewing dose-response literature.

BACKGROUND: Presently, there is limited guidance on the maximal dosing of psychosis drugs that is based on effectiveness rather than safety or toxicity. Current maximum dosing recommendations may far exceed the necessary degree of dopamine D2 receptor blockade required to treat psychosis. This may lead to excess harm through cognitive impairment and side effects. AIMS: This analysis aimed to establish guidance for prescribers by optimally dosing drugs for psychosis based on efficacy and benefit. METHODS: We used data from two dose-response meta-analyses and reviewed seven of the most prescribed drugs for psychosis in the UK. Where data were not available, we used appropriate comparison techniques based on D2 receptor occupancy to extrapolate our recommendations. RESULTS: We found that the likely threshold dose for achieving remission of psychotic symptoms was often significantly below the currently licensed dose for these drugs. We therefore recommend that clinicians are cautious about exceeding our recommended doses. Individual factors, however, should be accounted for. We outline potentially relevant factors including age, ethnicity, sex, smoking status and pharmacogenetics. Additionally, we recommend therapeutic drug monitoring as a tool to determine individual pharmacokinetic variation. CONCLUSIONS: In summary, we propose a new set of maximum target doses for psychosis drugs based on efficacy. Further research through randomised controlled trials should be undertaken to evaluate the effect of reducing doses from current licensing maximums or from doses that are above our recommendations. However, dose reductions should be implemented in a manner that accounts for and reduces the effects of drug withdrawal.

Effects of Prenatal Exposure to Second-Generation Antipsychotics on Development and Behavior Among Preschool-Aged Children: Preliminary Results From the National Pregnancy Registry for Psychiatric Medications.

Objective: Data are lacking on the neurodevelopmental outcomes of children prenatally exposed to second-generation antipsychotics (SGAs). The objective of this study is to examine neurodevelopmental outcomes of children exposed in utero to SGAs compared to those unexposed in a cohort of mothers with psychiatric morbidity.Methods: We conducted a cross-sectional assessment of preschool-aged children whose mothers were enrolled in the National Pregnancy Registry for Psychiatric Medications. Two validated, parent-report developmental and behavioral screening assessments, the Ages and Stages Questionnaire, Third Edition (ASQ-3) and the Preschool Child Behavior Checklist for Ages 1½-5 (CBCL/1½-5), respectively, were delivered electronically to eligible participants. Outcomes of children exposed in utero to SGAs were compared to those unexposed to SGAs in a cohort of mothers with a history of psychiatric illness. Exposure to other psychotropic medications during pregnancy was not an exclusion criterion for either group.Results: From January 2, 2018, to February 2, 2021, 520 children were eligible, and 352 responses were collected (67.7%), including 178 children in the SGA-exposed group (mean age = 2.6 years) and 174 children in the unexposed comparison group (mean age = 2.1 years). No significant differences between groups were detected (OR = 1.24, 95% CI, 0.74-2.09) with respect to developmental outcomes assessed by the ASQ-3. Similarly, for behavioral outcomes, adjusted analysis showed no significant differences in odds of an abnormal "clinical" score on the CBCL/1½-5 composite scales.Conclusions: The current study is the first to examine neurobehavioral outcomes of preschool-aged children exposed prenatally to SGAs. No significant differences in overall development or behavior were detected in the exposed versus unexposed group. These preliminary findings are an important step in delineating neurodevelopmental effects of prenatal SGA exposure.

Efficacy and tolerability of FDA-approved atypical antipsychotics for the treatment of bipolar depression: a systematic review and network meta-analysis.

We employed a Bayesian network meta-analysis for comparison of the efficacy and tolerability of US Food and Drug Administration (FDA)-approved atypical antipsychotics (AAPs) for the treatment of bipolar patients with depressive episodes. Sixteen randomized controlled trials with 7234 patients treated by one of the five AAPs (cariprazine, lumateperone, lurasidone, olanzapine, and quetiapine) were included. For the response rate (defined as an improvement of ≥50% from baseline on the Montgomery-Åsberg Depression Rating Scale [MADRS]), all AAPs were more efficacious than placebo. For the remission rate (defined as the endpoint of MADRS ≤12 or ≤ 10), cariprazine, lurasidone, olanzapine, and quetiapine had higher remission rates than placebo. In terms of tolerability, olanzapine was unexpectedly associated with lower odds of all-cause discontinuation in comparison with placebo, whereas quetiapine was associated with higher odds of discontinuation due to adverse events than placebo. Compared with placebo, lumateperone, olanzapine, and quetiapine showed higher odds of somnolence. Lumateperone had a lower rate of ≥ weight gain of 7% than placebo and other treatments. Olanzapine was associated with a significant increase from baseline in total cholesterol and triglycerides than placebo. These findings inform individualized prescriptions of AAPs for treating bipolar depression in clinical practice.
