Postnatal outcome of fetal cortical malformations: systematic review.

Ultrasound Obstet Gynecol

November 2024

Fetal Medicine Unit, St George's University Hospitals NHS Foundation Trust, University of London, London, UK.

Objective: Parental counseling for fetal malformations of cortical development (MCD) is based on data from studies in children and adults undergoing imaging investigation for abnormal neurodevelopment. However, such postnatal findings may not be applicable to prenatally diagnosed cases. The aim of this study was to review the existing data on postnatal neurodevelopmental outcome for fetuses diagnosed with MCD.

Article Synopsis
  • - The International League Against Epilepsy's (ILAE) Task Force created recommendations for diagnosing and treating anxiety and depression in kids with epilepsy after reviewing studies on screening measures and treatment effectiveness.
  • - Key recommendations for diagnosis include universal screening, closer monitoring for high-risk children, and using multiple sources to assess symptoms while emphasizing the importance of recognizing symptoms for better treatment outcomes.
  • - For treatment, individualized plans are advised, with monitoring for mild cases and referrals for more severe conditions, alongside the development of clinical care pathways and age-appropriate psychosocial interventions.

  • Despite advancements in treatment, ischaemic heart disease remains the top cause of illness and death among women, with many being underdiagnosed and undertreated.
  • Women face unique risk factors that increase their cardiovascular risk, necessitating a tailored approach in healthcare that includes both traditional and female-specific considerations.
  • The British Cardiovascular Society aims to highlight sex-related differences in CVD management, proposing solutions to improve access to diagnosis and treatment for women and encouraging further research on gender disparities in cardiovascular health.

GC-rich tandem repeat expansions (TREs) are often associated with DNA methylation, gene silencing and folate-sensitive fragile sites, and underlie several congenital and late-onset disorders. Through a combination of DNA-methylation profiling and tandem repeat genotyping, we identified 24 methylated TREs and investigated their effects on human traits using phenome-wide association studies in 168,641 individuals from the UK Biobank, identifying 156 significant TRE-trait associations involving 17 different TREs. Of these, a GCC expansion in the promoter of AFF3 was associated with a 2.

Paediatr Respir Rev

September 2024

Sloan School of Management, Massachusetts Institute of Technology, Cambridge, MA, USA; Department of Emergency Medicine, University of California San Francisco, CA, USA; Clinical Research, University of Southern Denmark, Copenhagen, Denmark.

Mask mandates for children were implemented at schools and childcare centers during the COVID-19 pandemic, and the US continues to recommend masking down to the age of two in certain settings. Medical interventions should be informed by high-quality evidence and consider the possibility of harm (i.e.

Article Synopsis
  • Researchers studied strokes from 1990 to 2021 to understand how many people get them and how they are affected around the world.
  • In 2021, strokes caused about 7.3 million deaths and were a major cause of health problems, especially in specific regions like Southeast Asia and Oceania.
  • There are differences in stroke risks based on where people live and their age, and some areas actually saw more strokes happening since 2015.

Mexiletine versus lamotrigine in non-dystrophic myotonias: a randomised, double-blind, head-to-head, crossover, non-inferiority, phase 3 trial.

Lancet Neurol

October 2024

Centre for Neuromuscular Disorders, The National Hospital for Neurology and Neurosurgery, London, UK; Queen Square Centre for Neuromuscular Diseases, UCL Queen Square Institute of Neurology, London, UK.

Background: Non-dystrophic myotonias are skeletal muscle channelopathies caused by ion channel dysfunction. Symptom onset is frequently in the first decade of life, causing disability in a young cohort. Although there is no cure, symptomatic treatments exist.

  • Anopheles melas, a lesser-known malaria-carrying mosquito, was studied for its population genetics in the Bijagós Archipelago, with the first whole-genome sequencing of this species in the area.
  • A total of 30 individual mosquitoes were sequenced, revealing no insecticide resistance mutations commonly found in other malaria mosquitoes, but some structural variations in relevant genes.
  • The findings also indicated two distinct genetic groups among the An. melas populations based on mitochondrial DNA, highlighting the need for further research to clarify their role in malaria transmission.

We assess the UK Biobank (UKB) Polygenic Risk Score (PRS) Release, a set of PRSs for 28 diseases and 25 quantitative traits that has been made available on the individuals in UKB, using a unified pipeline for PRS evaluation. We also release a benchmarking software tool to enable like-for-like performance evaluation for different PRSs for the same disease or trait. Extensive benchmarking shows the PRSs in the UKB Release to outperform a broad set of 76 published PRSs.

Background: Prompt diagnosis of bacteremia in the emergency department (ED) is of utmost importance. Nevertheless, the average time to first clinical laboratory finding range from 1 to 3 days. Alongside a myriad of scoring systems for occult bacteremia prediction, efforts for applying artificial intelligence (AI) in this realm are still preliminary.

Article Synopsis
  • The study explores fetal and offspring heart adaptations in cases of fetal growth restriction (FGR) compared to healthy controls over time.
  • Using advanced echocardiographic techniques, researchers found significant differences in heart geometry and function between FGR and healthy fetuses, including increased cardiac output and impaired diastolic function in FGR cases.
  • Findings suggest that changes in heart structure and function associated with FGR may be linked to chronic lack of oxygen from the placenta, potentially leading to long-term cardiovascular issues in affected children.

Article Synopsis
  • Research investigated the connection between patient volumes and healthcare outcomes in Austrian ICUs from 2013 to 2022, using data from a large patient registry.
  • Analyses revealed that lower ICU utilization (≤ 75%) correlated with increased mortality, whereas high occupancy (>100%) showed significant associations only during the COVID-19 pandemic.
  • The study concluded that within systems with adequate resources, overall staffing does not significantly impact patient survival, although specific workload levels may still pose risks.

Nonictal electroencephalographic measures for the diagnosis of functional seizures.

Epilepsia

November 2024

Centre for Biomedical Engineering, School of Mechanical Engineering Sciences, University of Surrey, Guildford, UK.

Objective: Functional seizures (FS) look like epileptic seizures but are characterized by a lack of epileptic activity in the brain. Approximately one in five referrals to epilepsy clinics are diagnosed with this condition. FS are diagnosed by recording a seizure using video-electroencephalography (EEG), from which an expert inspects the semiology and the EEG.
