Can Large Language Models Aid Caregivers of Pediatric Cancer Patients in Information Seeking? A Cross-Sectional Investigation.

Purpose: Caregivers in pediatric oncology need accurate and understandable information about their child's condition, treatment, and side effects. This study assesses the performance of publicly accessible large language model (LLM)-supported tools in providing valuable and reliable information to caregivers of children with cancer.

Methods: In this cross-sectional study, we evaluated the performance of the four LLM-supported tools-ChatGPT (GPT-4), Google Bard (Gemini Pro), Microsoft Bing Chat, and Google SGE-against a set of frequently asked questions (FAQs) derived from the Children's Oncology Group Family Handbook and expert input (In total, 26 FAQs and 104 generated responses).

Extracellular Vesicles from Mesenchymal Stem Cells: Potential as Therapeutics in Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD).

Metabolic dysfunction-associated steatotic liver disease (MASLD) is characterized by the accumulation of triglycerides within hepatocytes, which can progress to more severe conditions, such as metabolic dysfunction-associated steatohepatitis (MASH), which may include progressive fibrosis, leading to cirrhosis, cancer, and death. This goal of this review is to highlight recent research showing the potential of mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) in reducing the key pathogenic pathways of MASLD or MASH. Relevant published studies were identified using PubMed with one or more of the following search terms: MASLD, MASH, NAFLD, NASH, exosome, extracellular vesicle (EV), therapy, and/or mesenchymal stem cells (MSC).

Identifying fatal poisonings using child fatality review, poison centre and death certificate data in the USA.

Background: Three sources used for poisoning surveillance-child fatality reviews (CFRs), poison centre (PC) calls and death certificates-employ disparate data methodologies. Our study objectives were to (1) characterise the number of fatalities captured by CFRs and PC data compared with death certificates by age and (2) compare demographic and substance characteristics of fatalities captured by the three sources.

Methods: We acquired CFR data from the National Fatality Review-Case Reporting System (NFR-CRS), PC calls from the National Poison Data System (NPDS) and death certificate data from Centers for Disease Control and Prevention's Wide-ranging Online Data for Epidemiologic Research (WONDER) on poisoning fatalities among children 0-17 years old between 2005 and 2020.

Should healthcare organizations be accountable for child community health indicators at the community level?

Purpose Of Review: This paper reviews options for including community health accountability metrics for child healthcare systems, international and regional experience with such metrics, and some specific candidates for metric consideration.

Recent Findings: The inclusion of community metrics in child health accountability systems requires expanded accountability frameworks and re-education of clinicians. Most of the experience with use of community metrics in accountability systems comes from international settings.

PPARγ Promotes Urothelial Remodeling During Urinary Tract Obstruction.

Urinary tract obstruction (UTO) is a common cause of kidney injury that can result in chronic kidney disease and end-stage renal disease. Heterogeneity in the extent of obstructive renal damage in humans with UTO implies the existence of unknown mechanisms that protect against or accelerate kidney injury. Prior studies show that congenital and acquired UTO initiate a conserved, protective program of renal urothelium remodeling that culminates in expansion of uroplakin (UPK)+ cells to promote renal structural integrity.

Prospective observational study of FKRP-related limb-girdle muscular dystrophy R9: A GRASP consortium study.

Objective: Limb-girdle muscular dystrophy R9 (LGMDR9, formerly known as LGMD2I), caused by variants in the fukutin-related protein (FKRP) gene leads to progressive muscle weakness of the shoulder and pelvic limb-girdles and loss of motor function over time. Clinical management and future trial design are improved by determining which standardized clinical outcome assessments (COA) of function are most appropriate to capture disease presentation and progression, informing endpoint selection and enrollment criteria. The purpose of our study was to evaluate the cross-sectional validity and reliability of clinical outcome assessments in patients with FKRP-related LGMDR9 participating in the Genetic Resolution and Assessments Solving Phenotypes in LGMD (GRASP) natural history study.

RPA and Rad27 limit templated and inverted insertions at DNA breaks.

Formation of templated insertions at DNA double-strand breaks (DSBs) is very common in cancer cells. The mechanisms and enzymes regulating these events are largely unknown. Here, we investigated templated insertions in yeast at DSBs using amplicon sequencing across a repaired locus.

The predictive effect of ASD on PTSD and the factors influencing ASD and PTSD.

Objective: To investigate the prevalence and influencing factors of acute stress disorder (ASD) and post-traumatic stress disorder (PTSD) in trauma patients, and to explore the predictive effect of ASD on PTSD.

Methods: A prospective study was conducted on patients hospitalized due to injuries. The first survey used the ASD scale to assess the occurrence of ASD.

Benefit-finding in children with advanced cancer and their parents.

Objectives: Although pediatric cancer often causes significant stress for families, most childhood cancer survivors are resilient and do not exhibit severe or lasting psychopathology. Research demonstrates some survivors may report benefit-finding or positive outcomes following this stressful life event. However, considerably less research has included families of children who are unlikely to survive their illness.

Optical Genome Mapping (OGM) Identifies Multiple Structural Variants in a Case With Atypical Phelan-McDermid Syndrome.

Here we describe a neonate exhibiting hypotonia, macrocephaly, renal cysts, and respiratory failure requiring tracheostomy and ventilator support. Genetic analysis via rapid genome sequencing (rGS) identified a loss on chromosome 4 encompassing polycystin-2 (PKD2) and a loss on chromosome 22 encompassing SH3 and Multiple Ankyrin Repeat Domains 3 (SHANK3), indicative of Phelan-McDermid syndrome. Further analysis via traditional karyotyping, Optical Genome Mapping (OGM), and PacBio long-read sequencing revealed a more complex landscape of chromosomal rearrangements in this individual, including a balanced 3;12 translocation, and an unbalanced 17;22 translocation.

Empiric antibiotic prescribing practices for gram-positive coverage of late-onset sepsis in neonatal intensive care units in North America.

Late-onset sepsis (LOS) in the neonatal intensive care unit (NICU) causes significant morbidity and mortality, yet guidance on empiric management is limited. We surveyed NICUs across Canada and the United States regarding their empiric antimicrobial regimens for LOS, thereby identifying large practice variations and high rates of empiric vancomycin use.

Gabapentin and pregabalin exposures reported to United States poison centers, 2012-2022.

Background: Gabapentin and pregabalin were originally introduced as anticonvulsant medications but are now also prescribed on- and off-label for multiple medical disorders, especially for pain management. The national opioid crisis has led to increased use of non-opioid pain medications, including gabapentinoids, which has been associated with changing patterns of adverse events associated with these medications. This study investigated the characteristics and trends of gabapentin and pregabalin exposures reported to US poison centers from 2012 to 2022.

Characteristics of Fatalities Among Sexual- and Gender-Diverse Youth in the United States: 2015-2020.

Objectives: Sexual- and gender-diverse youth face unique stressors that negatively impact their health. The objective of this study was to use National Fatality Review-Case Reporting System data to epidemiologically describe fatalities among identified sexual- and gender-diverse youth to inform future prevention efforts.

Methods: We used 2015 to 2020 data from the National Fatality Review-Case Reporting System to identify deaths among sexual- and gender-diverse youth and compare their characteristics to a matched sample of youth from these same data who were not known to be sexual- and gender-diverse.
