AI Article Synopsis

  • Research on medical countermeasures (MCMs) for lung injuries caused by radiation requires reliable animal models that accurately simulate human conditions to ensure the findings are applicable to humans.
  • Understanding the strengths and weaknesses of different animal models is crucial for demonstrating the effectiveness of these countermeasures in treating radiation-induced damage.
  • A meeting held on March 20, 2019, by the Radiation and Nuclear Countermeasures Program gathered various stakeholders to discuss research gaps and the use of animal models in studying radiation-induced lung damage.

Article Abstract

Research and development of medical countermeasures (MCMs) for radiation-induced lung injury relies on the availability of animal models with well-characterized pathophysiology, allowing effective bridging to humans. To develop useful animal models, it is important to understand the clinical condition, advantages and limitations of individual models, and how to properly apply these models to demonstrate MCM efficacy. On March 20, 2019, a meeting sponsored by the Radiation and Nuclear Countermeasures Program (RNCP) within the National Institute of Allergy and Infectious Diseases (NIAID) brought together medical, scientific and regulatory communities, including academic and industry subject matter experts, and government stakeholders from the Food and Drug Administration (FDA) and the Biomedical Advanced Research and Development Authority (BARDA), to identify critical research gaps, discuss current clinical practices for various forms of pulmonary damage, and consider available animal models for radiation-induced lung injury.

Background: In radioembolization therapy for hepatic malignancies, the accurate estimation of lung shunt fraction (LSF) is crucial to minimize the risk of radiation-induced pneumonitis and fibrosis due to hepatopulmonary shunting of yttrium-90 (90Y)-microspheres. This study aimed to compare the accuracy and precision of LSF estimation using technetium-99m macroaggregated albumin single photon emission computed tomography ([99mTc]Tc-MAA SPECT) LSF, [99mTc]Tc-MAA planar LSF, and 90Y PET LSF in patients undergoing 90Y-radioembolization.

Material And Methods: A retrospective study was conducted involving 15 patients diagnosed with hepatocellular carcinoma (HCC) or liver metastases and planned to undergo transarterial radioembolization with 90Y SirSpheres after multidisplinary team discussion.

Unlabelled: Problem of the causal relationship of disease that became the reason of death with the effect of ionizing radiation and due to harmful influence of the Chornobyl Catastrophe during performance of professional, military or official duties and / or living on radiation-contaminated areas, additional exposure not through their own fault but due to a radiation accident, caused the development of a special form of medical expertise as part of the of medical social protection system for suffered contingents in the remote postaccidental period.

Objective: To study and characterize the structure of the survivor categories (clean-up workers and victims) of the Chernobyl Catastrophe in the remote post-accident period (2013-2024) regarding the causal relationship of disease that became the reason of death with the effect of ionizing radiation and due to harmful influence of the Chornobyl Catastrophe based on the materials of expert cases of the Central Interdepartmental Expert Commission of the Ministry of Health of Ukraine (CIEC).

Material And Methods: The work was performed in the design of a retrospective study that based on analysis of the structure of all categories of Chornobyl NPP accident (ChNPP) survivors during 2008-2024 years and studying of 58,137 medical expert cases, including 19,524 postmortem cases, which were considered by CIEC during 2013-2023 to establish a causal relationship between the disease and influence of radiation exposure and other harmful factors and conditions during ChNPP accident.

Background: Patients receiving chest radiation therapy, or exposed to high radiation levels due to accidental nuclear leakage are at risk of radiation-induced lung injury (RILI). In innate immunity, macrophages not only exhibit certain radiation tolerance but also play an important regulatory role in the whole pathological process. Nervonic acid (NA), a long-chain unsaturated fatty acid found in nerve tissue, plays a pivotal role in maintaining normal tissue growth and repair.

Purpose: Our study aims to develop and validate a novel molecular marker for the prognosis and diagnosis of hepatocellular carcinoma (HCC) MATERIALS & METHODS: We retrospectively analyzed mRNA expression profile and clinicopathological data of HCC patients fetched from The Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO) and The International Cancer Genome Consortium (ICGC) datasets. Univariate Cox regression analysis was performed to collect differentially expressed mRNA (DEmRNAs) from HCC and non-tumor tissues, and YEATS2, a prognostic marker, was identified by further analysis. ROC curve, survival analysis and multivariate Cox regression analysis as well as nomograms were used to evaluate the prognosis of this gene.
