This report presents the case of a seven-year-old child diagnosed with Grisel's syndrome following a craniotomy for a cystic brain lesion. The patient initially presented with persistent, progressively worsening headaches that coincided with neurological symptoms. Imaging revealed a massive cystic lesion causing a significant compression and midline shift.

Background: Myriad risk factors contribute to pediatric influenza vaccination disparities. Digital stories are compelling accounts of lived experience that have been useful in health promotion, especially in minoritized communities. Little is known about how they are perceived as a behavioral intervention to improve influenza vaccination confidence in safety-net healthcare systems.

Vein of Galen malformations (VOGMs) are rare and complex congenital vascular anomalies that can lead to severe morbidity and mortality. Management predominantly focuses on postnatal endovascular interventions. However, these may not be feasible for fetuses with hemodynamic instability and high-output cardiac failure and may fail to prevent irreversible brain damage induced by prolonged compression by the venous varix, hemodynamic alterations and resultant potential ischemic injury.

Background And Objectives: Nearly one-third of individuals with epilepsy have drug-resistant epilepsy, treated most effectively with surgery. This study aims to discuss the demographic profile, surgical access, and strategies used in drug-resistant epilepsy in Africa.

Methods: A systematic review was performed using PubMed, Google Scholar, Embase, and Web of Science in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.

Minimally invasive neural interfaces can be used to diagnose, manage and treat many disorders, with reduced risks of surgical complications. However, endovascular probes lack access to key cortical, subcortical and spinal targets, and are not typically explantable after endothelialization. Here we report the development and testing, in sheep, of endocisternal neural interfaces that approach brain and spinal cord targets through inner and outer spaces filled with cerebrospinal fluid.

Aims: The aim of this study was to compare patient-reported outcomes (PROMs) following isolated anterior cruciate ligament reconstruction (ACLR), with those following ACLR and concomitant meniscal resection or repair.

Methods: We reviewed prospectively collected data from the UK National Ligament Registry for patients who underwent primary ACLR between January 2013 and December 2022. Patients were categorized into five groups: isolated ACLR, ACLR with medial meniscus (MM) repair, ACLR with MM resection, ACLR with lateral meniscus (LM) repair, and ACLR with LM resection.

Purpose: Vaccination rates are significantly lower among adolescents living in rural areas compared to those living in urban areas. The objective of this study was to understand the factors contributing to disparities in vaccination between adolescents in rural compared to urban areas.

Methods: Semi-structured qualitative interviews were conducted with parents and providers in 16 rural and 4 urban counties of Colorado.

To assess multilevel factors associated with variation in COVID-19 vaccination rates in a US network of community health centers. Using multilevel logistic regression with electronic health record data from ADVANCE (Accelerating Data Value Across a National Community Health Center Network; January 1, 2022-December 31, 2022), we assessed associations between health care delivery site-level (n = 1219) and patient-level (n = 1 864 007) characteristics and COVID-19 primary vaccine series uptake. A total of 1 337 440 patients completed the COVID-19 primary vaccine series.

How eukaryotic ribosomes traverse messenger RNA (mRNA) leader sequences to search for protein-synthesis start sites remains one of the most mysterious aspects of translation and its regulation. While the search process is conventionally described by a linear "scanning" model, its exquisitely dynamic nature has restricted detailed mechanistic study. Here, we observed single ribosomal scanning complexes in real time, finding that they scan diverse mRNA leaders at a rate of 10 to 20 nt s.

Article Synopsis
  • Immunization disparities have increased in the past two years due to the pandemic, conflicts, and economic issues affecting healthcare systems.
  • The review presents a framework for understanding these disparities and highlights initiatives aimed at promoting immunization equity.
  • It covers the WHO's priorities for vaccination equity, specific campaigns in conflict zones like Ukraine, successful COVID-19 responses in Ghana, and Brazil's strategies to combat stigma and build trust in mpox vaccines.

Neurotrauma registries (NTR) collect data on traumatic brain injuries (TBI) to advance knowledge, shape policies, and improve outcomes. This study reviews global NTRs from High-Income (HICs) and Low- and Middle-Income countries (LMICs). A systematic review was conducted using PubMed, Google Scholar, Embase, and Web of Science following PRISMA guidelines to identify relevant NTRs.

Objective: Pediatric coronavirus disease 2019 (COVID-19) vaccination rates remain low in rural areas. A strong clinician recommendation improves vaccine uptake, but the pediatric COVID-19 vaccine recommendation practices of rural primary care clinicians have not been reported. Our objectives were to describe, among rural Colorado pediatric clinicians: 1) recommendation practices for COVID-19 vaccine compared to influenza and school-entry required vaccines, and 2) personal attitudes.

Background And Objectives: Studies note a high prevalence of pediatric coronavirus disease 2019 (COVID-19)-specific vaccine hesitancy in the United States. Our objective was to assess whether clinicians perceive a spillover effect of COVID-19 vaccine hesitancy onto other vaccines, and the impact of this spillover on their general recommendation behavior.

Methods: We conducted semistructured interviews with pediatricians in California and Colorado pediatric practices (January-March 2023).

Background Patients utilize online health information to inform their medical decision-making. YouTube is one of the most popular media platforms with abundant health-related resources, yet the quality of the disseminated information remains unclear. This study aims to evaluate the quality and reliability of content pertaining to diverticulosis and diverticulitis on YouTube.

The Advisory Committee on Immunization Practices (ACIP), a group of medical and public health experts that provides advice to the Centers for Disease Control and Prevention, normally meets 3 times per year to develop US vaccine recommendations. The ACIP met June 26 through 28, 2024. This update summarizes the proceedings of this meeting, with an emphasis on topics that are most relevant to the pediatric population.

Article Synopsis
  • Anterior cruciate ligament (ACL) injuries in the knee often lead to decreased activity levels and a higher risk of osteoarthritis, and there’s a lack of clear guidelines for managing these injuries either through surgery or rehabilitation.
  • This study aimed to compare the effectiveness and cost of surgical ACL reconstruction without prior rehab against a rehabilitation approach before surgery for patients with non-acute ACL injuries and symptoms of instability.
  • Conducted across 29 NHS orthopedic units in the UK, the trial tracked key outcomes like knee function and patient satisfaction over 18 months in 316 participants.
