Seizures are common in neonates, but there is substantial management variability. The Neonatal Task Force of the International League Against Epilepsy (ILAE) developed evidence‐based recommendations about antiseizure medication (ASM) management in neonates in accordance with ILAE standards. Six priority questions were formulated, a systematic literature review and meta‐analysis were performed, and results were reported following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta‐Analyses) 2020 standards. Bias was evaluated using the Cochrane tool and risk of Bias in non‐randomised studies ‐ of interventions (ROBINS‐I), and quality of evidence was evaluated using grading of recommendations, assessment, development and evaluation (GRADE). If insufficient evidence was available, then expert opinion was sought using Delphi consensus methodology. The strength of recommendations was defined according to the ILAE Clinical Practice Guidelines development tool. There were six main recommendations. First, phenobarbital should be the first‐line ASM (evidence‐based recommendation) regardless of etiology (expert agreement), unless channelopathy is likely the cause for seizures (e.g., due to family history), in which case phenytoin or carbamazepine should be used. Second, among neonates with seizures not responding to first‐line ASM, phenytoin, levetiracetam, midazolam, or lidocaine may be used as a second‐line ASM (expert agreement). In neonates with cardiac disorders, levetiracetam may be the preferred second‐line ASM (expert agreement). Third, following cessation of acute provoked seizures without evidence for neonatal‐onset epilepsy, ASMs should be discontinued before discharge home, regardless of magnetic resonance imaging or electroencephalographic findings (expert agreement). Fourth, therapeutic hypothermia may reduce seizure burden in neonates with hypoxic–ischemic encephalopathy (evidence‐based recommendation). Fifth, treating neonatal seizures (including electrographic‐only seizures) to achieve a lower seizure burden may be associated with improved outcome (expert agreement). Sixth, a trial of pyridoxine may be attempted in neonates presenting with clinical features of vitamin B6‐dependent epilepsy and seizures unresponsive to second‐line ASM (expert agreement). Additional considerations include a standardized pathway for the management of neonatal seizures in each neonatal unit and informing parents/guardians about the diagnosis of seizures and initial treatment options.

Summary: The aim of this study was to evaluate whether specific etiologies of neonatal seizures have distinct ictal electroclinical features. A systematic review of English articles using the PubMed database since 2004 (last update 9/26/16). Search terms included text words and Medical Subject Headings (MeSH)terms related to neonatal seizures. Eligible articles included reports of neonates with seizures with a full description of seizure semiology and electroclinical findings. Independent extraction of data was performed by 2 authors using predefined data fields, including study quality indicators. Data were collected for every individual patient described in the articles. The dataset was analyzed with the Fisher exact test. The initial search led to 8507 titles; using filters, 2910 titles and abstracts were identified, with 177 full texts selected to be read. Fifty‐seven studies were included in the analysis with 151 neonates (37.7 male and 62.9% term). Genetic etiologies (51%) and sequential seizures (41.1%) predominated in this sample and hypoxic‐ischemic encephalopathy (HIE) accounted for only 4%. The low prevalence ofHIEobserved was probably due to a publication bias. A significant association was found between etiology and seizure type: hemorrhage with autonomic seizures (P = 0.003),central nervous system (CNS)infection and stroke with clonic seizures (P = 0.042,P < 0.001, respectively), metabolic/vitamin‐related disorders, and inborn errors of metabolism with myoclonic seizures (P < 0.001). There were also specific electroencephalography (EEG)patterns seen with certain etiologies: vascular disorders and electrolyte imbalance with focal ictal discharges (P < 0.001,P = 0.049 respectively), vitamin‐related disorders with multifocal (P = 0.003), and all categories of genetic disorders with burst‐suppression (P < 0.001). Clonic and autonomic seizures were more frequently present with focalEEGabnormalities (P = 0.001 andP < 0.001), whereas tonic and myoclonic seizures present with burst‐suppression (P = 0.001,P = 0.005). In conclusion, our data suggest that specific associations of etiologies of neonatal seizures with distinct clinical features andEEGpatterns might help in the decision to establish appropriate treatment.

This study aimed to review the literature, summarizing the existing evidence on the effects of the pandemic on children, adolescents and parents, with an emphasis on the psychological, emotional, and sleep quality consequences. Empirical studies identified in the following databases: MEDLINE, ISI Web of Knowledge/Web of Science, and preprint servers. The findings point to a wide range of consequences for children and adolescents resulting from the COVID-19 pandemic, which mainly includes an increase in depressive mood symptoms. There is also an increase in anxiety symptoms, suicidal ideation, as well as potential delays in language and motor development resulting from deprivation of social interaction and the closing of schools. These effects are more severe due to previous neuropsychiatric conditions. For parents, there is an increase in anxiety, depressive and post-traumatic symptoms, which are more accentuated in those who suffered socioeconomic damage due to the pandemic. There was an important increase in situations of violence towards children by parents and caregivers during the pandemic. Also, changes in routine and fear of the pandemic have negatively impacted sleep quality, globally. It is noteworthy that most studies published to date used a cross-sectional design and applied online screening questionnaires. The few studies with a longitudinal design suggest that these changes may have been transitory and more prevalent at the beginning of the pandemic.

To evaluate sleep characteristics of parents and their children during the COVID-19 pandemic and predictors for sleep disturbances. Cross-sectional web-based study using an online survey made available for dyads of parents and their children during the 7th week of quarantine in southern Brazil. Parents' and adolescents’ sleep were characterized using the Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale. For children aged 0-3 years parents completed the Brief Infant Sleep Questionnaire, for those aged 4-12 years the Sleep Disturbance Scale for Children. Parents also informed, subjectively, their perception about sleep habits during social distancing. Multiple regression was run to predict sleep disturbances in adults using independent variables: sex, income, education, children age, and children with sleep disturbances. Data from 577 dyads showed sleep alterations in 69,8% of adults, in 58,6% of children aged 0-3 years, 33,9% in the 4-12 years range (with a predominance of disorders of initiating or maintaining sleep), and 56,6% in adolescents. Sex (female) and children with sleep disturbances were significant predictors of a sleep problem in parents (p < 0.005). Subjective perception revealed complaints related to emotional concerns such as anxiety and fear in adults and due to alterations in routine in children and adolescents. The present study's data showed an increased rate of sleep problems among families during quarantine both measured by validated instruments and also based on personal perception.
