Major nuclear accidents can result in many casualties, and it is important to assess the absorbed radiation dose to support treatment decisions. Biological dosimetry (BD) allows retrospective determination of dose using biological markers. To achieve consistent cytogenetic assay results across labs, the current practice requires each lab to generate periodic, unique calibration curves using in vitro dose-effect experiments. Here, we present CytoRADx™, a standardized biodosimetry system that integrates automated dose calculation in a high-throughput platform without the need for lab-specific calibration curves. CytoRADx consists of an improved, standardized Cytokinesis Block Micronucleus assay combined with automated analysis utilizing an established slide scanning device. We tested CytoRADx for accuracy and reproducibility across different instruments, sites, days and operators. Our results demonstrate that CytoRADx eliminates the time-consuming, lab-specific calibration curves, allowing multiple laboratories to obtain consistent results and to distribute the testing burden in the event of a large-scale accident.

Department of Traditional Chinese Medicine, The First Hospital of Hebei Medical University Shijiazhuang 050091, Hebei, China.
Objective: To develop predictive models for assessing deep vein thrombosis (DVT) risk among lumbar disc herniation (LDH) patients and evaluate their performances.
Methods: A retrospective study was conducted on 798 LDH patients treated at the First Hospital of Hebei Medical University from January 2017 to December 2023. The patients were divided into a training set (n = 558) and a test set (n = 240) using computer-generated random numbers in a ratio of 7:3.

Objective: To identify independent risk factors for Henoch-Schönlein purpura nephritis (HSPN) in pediatric patients.
Methods: This study enrolled 180 pediatric patients (90 with HSP, 90 with HSPN) hospitalized at the 940th Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from December 2022 to October 2023, with a follow-up of at least six months. Clinical data were collected at the time of the first onset of HSP.

Objective: To investigate the association between the basic and clinical characteristics of patients with type 2 diabetes mellitus (T2DM) and their susceptibility to Klebsiella pneumoniae colonization (KPC). Additionally, a clinical prediction model was developed to identify high-risk patients for KPC.
Methods: Data from 486 T2DM patients who visited Shanghai Fifth People's Hospital from December 2020 to December 2022 were retrospectively collected.

Background: Ultrasound based radiomics prediction model can improve the differentiation ability of benign and malignant thyroid nodules to avoid overtreatment. This study evaluates the role of predictive models based on intranodular and perinodular ultrasound radiomics in distinguishing between benign and malignant thyroid nodules.
Methods: A total of 1,076 thyroid nodules were enrolled from three hospitals between 2016 and 2022, forming the training, validation and test cohorts.

Background: Breast cancer-related lymphedema (BCRL) is one of the common complications after breast cancer surgery. It can easily lead to limb swelling, deformation and upper limb dysfunction, which has a serious impact on the physical and mental health and quality of life of patients. Previous studies have mostly used statistical methods such as linear regression and logistic regression to analyze the influencing factors, but all of them have certain limitations.
