Indirect effects of the COVID-19 pandemic on malaria intervention coverage, morbidity, and mortality in Africa: a geospatial modelling analysisSubstantial progress has been made in reducing the burden of malaria in Africa since 2000, but those gains could be jeopardised if the COVID-19 pandemic affects the availability of key malaria control interventions. The aim of this study was to evaluate plausible effects on malaria incidence and mortality under different levels of disruption to malaria control.

An observational study of hypoactive delirium in the post-anesthesia recovery unit of a pediatric hospitalHypoactive delirium is present when an awake child is unaware of his or her surroundings, is unable to focus attention, and appears quiet and withdrawn. This condition has been well-described in the intensive care setting but has not been extensively studied in the immediate post-anesthetic period. The aim was to determine if hypoactive emergence delirium occurs in the recovery unit of a pediatric hospital, and if so, what proportion of emergence delirium is hypoactive in nature.

Assessment of Cannabidiol and Delta9-Tetrahydrocannabiol in Mouse Models of Medulloblastoma and EpendymomaChildren with medulloblastoma and ependymoma are treated with a multidisciplinary approach that incorporates surgery, radiotherapy, and chemotherapy; however, overall survival rates for patients with high-risk disease remain unsatisfactory. Data indicate that plant-derived cannabinoids are effective against adult glioblastoma; however, preclinical evidence supporting their use in pediatric brain cancers is lacking. Here we investigated the potential role for Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) in medulloblastoma and ependymoma. Dose-dependent cytotoxicity of medulloblastoma and ependymoma cells was induced by THC and CBD in vitro, and a synergistic reduction in viability was observed when both drugs were combined.

The Human Phenotype Ontology in 2021The Human Phenotype Ontology was launched in 2008 to provide a comprehensive logical standard to describe and computationally analyze phenotypic abnormalities found in human disease. The HPO is now a worldwide standard for phenotype exchange. The HPO has grown steadily since its inception due to considerable contributions from clinical experts and researchers from a diverse range of disciplines. Here, we present recent major extensions of the HPO for neurology, nephrology, immunology, pulmonology, newborn screening, and other areas.

Minimal structural lung disease in early life represents significant pathologyIn this cohort, as compared with the AREST CF cohort, the authors highlight the limited correlation between infection and inflammation with lung function and structural impairment, and that this was mainly explained by the mild changes identified in lung function and on chest CT scan.

Financial Interventions to Increase Vaccine CoverageRecent vaccine mandates in Australia, as in other high income settings, have sought to change the behavior of parents, including those who would otherwise access nonmedical exemptions. Since 2014, Australian state governments have introduced and progressively tightened policies restricting the access of unvaccinated children to early education and child care.

IRF7-Associated Immunophenotypes Have Dichotomous Responses to Virus/Allergen Coexposure and OM-85-Induced ReprogrammingHigh risk for virus-induced asthma exacerbations in children is associated with an IRF7lo immunophenotype, but the underlying mechanisms are unclear. Here, we applied a Systems Biology approach to an animal model comprising rat strains manifesting high versus low susceptibility to experimental asthma, induced by virus/allergen coexposure, to elucidate the mechanism(s)-of-action of the high-risk asthma immunophenotype.

The perceived effects of cannabis products in the management of seizures in CDKL5 Deficiency DisorderCDKL5 Deficiency Disorder (CDD) is a severe treatment-resistant form of early-onset epilepsy. Current treatment options are often ineffective and associated with adverse effects, forcing families to seek alternative therapies for their children including products derived from cannabis. Reportsof miraculous cures and a public preferencefor 'natural' therapies have resulted in considerable public interest, and so this study aimed to characterize the use of cannabis in these individuals, as well as compare caregiver perceptions of efficacy and safety to objective evidence of seizure control and number of antiepileptic drugs used.

Nasal airway epithelial repair after very preterm birthNasal epithelial cells from very preterm infants have a functional defect in their ability to repair beyond the first year of life, and failed repair may be associated with antenatal steroid exposure.

Bacterial and Fungal Gut Community Dynamics Over the First 5 Years of Life in Predominantly Rural Communities in GhanaBacterial and fungal microbiotas are increasingly recognized as important in health and disease starting early in life. However, microbiota composition has not yet been investigated in most rural, low-resource settings, and in such settings, bacterial and fungal microbiotas have not been compared.
