Adults with congenital heart disease (CHD) benefit from cardiology follow-up at recommended intervals of ≤ 2 years. However, benefit for children is less clear given limited studies and unclear current guidelines. We hypothesize there are identifiable risks for gaps in cardiology follow-up in children with CHD and that gaps in follow-up are associated with differences in healthcare utilization.

Globally rising antibiotic-resistant (AR) and multi-drug resistant (MDR) bacterial infections are of public health concern due to treatment failure with current antibiotics. Enterobacteria, particularly Escherichia coli, cause infections of surgical wound, bloodstream, and urinary tract, including pneumonia and sepsis. Herein, we tested in vitro antibacterial efficacy, mode of action (MoA), and safety of novel amino-functionalized silver nanoparticles (NH-AgNP) against the AR bacteria.

We present Transkingdom Network Analysis (TkNA), a unique causal-inference analytical framework that offers a holistic view of biological systems by integrating data from multiple cohorts and diverse omics types. TkNA helps to decipher key players and mechanisms governing host-microbiota (or any multi-omic data) interactions in specific conditions or diseases. TkNA reconstructs a network that represents a statistical model capturing the complex relationships between different omics in the biological system.

Article Synopsis
  • Volume overload from mitral regurgitation can lead to left ventricular (LV) dysfunction, making timely surgical intervention crucial, though the best timing is still debated.
  • A study analyzed data from 243 patients who underwent mitral valve repair, comparing predictors of post-operative LV systolic dysfunction using both CT-based and 2D echocardiographic methods.
  • Results showed that CT measurements of ejection fraction and LV end systolic volume were more effective predictors of post-operative dysfunction compared to echocardiographic measures, pointing to the potential superiority of CT in this context.

The move toward early detection and treatment of cancer presents challenges for value assessment using traditional endpoints. Current cancer management rarely considers the full economic and societal benefits of therapies. Our study used a modified Delphi process to develop principles for defining and assessing value of cancer therapies that aligns with the current trajectory of oncology research and reflects broader notions of value.

Multiple sclerosis (MS) is an inflammatory and demyelinating disease of the central nervous system (CNS). Current therapies primarily target the inflammatory component of the disease and are highly effective in early stages of MS while limited therapies have an effect in the more chronic progressive stages of MS where resident glia have a larger role. MS lesions tend to be inflammatory even after the initial peripheral immune cell invasion has subsided and this inflammation is known to cause alternative splicing events.

Superabsorbent polymer (SAP) granules, typically used in personal care devices such as diapers, incontinence devices, hygiene pads, and wound dressings, and granular particles of zeolite and bentonite were each subjected to modification by exposure to solutions of 1-chloro-2,2,5,5-tetramethyl-4-imidazolidinone (MC) in ethanol at room temperature. The air-dried granules showed newly acquired properties attributable to the presence of active chlorine (Cl). The treated particles effectively oxidized the malodorant 3-mercapto-3-methylbutanol (3M3MB).

Article Synopsis
  • Respiratory syncytial virus (RSV) is a major cause of hospitalization in infants in the U.S., prompting the CDC to recommend nirsevimab, a monoclonal antibody, for infants under 8 months and at-risk children aged 8-19 months to prevent severe infection during their first RSV season.
  • In clinical trials, nirsevimab showed an 81% efficacy rate for preventing RSV-related hospitalizations, while a recent analysis during RSV season (October 2023-February 2024) reported a 90% effectiveness among treated infants.
  • Despite limited numbers of treated infants, the findings support ongoing recommendations for nirsevimab and emphasize the importance of maternal vaccination or direct nirsevimab administration

Article Synopsis
  • Folic acid is essential for preventing neural tube defects, leading the FDA to allow voluntary fortification of corn masa flour to help Hispanic women of reproductive age who may lack other sources of this nutrient.
  • A study using NHANES data from 2011 to March 2020 found no significant changes in folic acid intake or red blood cell folate levels among Hispanic women after the fortification was implemented.
  • The results indicate that while voluntary fortification exists, it hasn't yet significantly improved folate status, suggesting the need for ongoing monitoring and further research to understand and enhance public health efforts.

Article Synopsis
  • Researchers face challenges in interpreting immunogenicity results and predicting clinical outcomes for monoclonal antibody (mAb) products, despite advancements in methodologies.
  • The contribution from clinical pharmacology has mainly involved comparing pharmacokinetic profiles based on the presence of antidrug antibodies (ADA) and evaluating ADA as a factor in drug behavior, similar to small-molecule drugs.
  • A new framework that analyzes mAb disposition, focusing on ADA formation and interactions, was developed and tested using data from a phase 3 trial of adalimumab, showing potential for improved understanding and predictions for drug effectiveness and dosing strategies.
