An AI Algorithm for Lymphocyte Focus Score of Minor Salivary Gland Biopsy Samples for Diagnosing Sjogren's Syndrome
The aim of this research is to discover an artificial intelligence (AI) algorithm for lymphocyte focus score in whole slide images of labial minor salivary gland (SG) biopsy samples for diagnosing Sjogren's Syndrome, in order to enhance the precision of pathological interpretation of labial minor SG biopsy samples in patients …
Pre-warning Risk Scoring System for Sudden Cardiac Death
The goal of this observational study is to identify potential indicators for pre-warning of sudden cardiac death (SCD), including clinical biochemistry markers, electrocardiogram, echocardiography, MRI and CT imaging values, genetic markers and so on, and further construct a series of multi-parameter assessments of SCD early screening.
Diagnostic Accuracy of EBV C Promoter Methylation Kit in Nasopharyngeal Carcinoma
This clinical study aims to evaluate the diagnostic performance of a new Epstein-Barr virus (EBV) C promoter methylation detection kit. All participants will undergo a series of diagnostic tests including VCA-IgA, EBNA1-IgA, and EBV-DNA assays. Additionally, nasopharyngeal swabs will be analyzed for EBV C promoter methylation. Confirmatory biopsy will be …
Prediction and Evaluation by ETCOc of Neonatal Hyperbilirubinemia Cohort
The hemolytic disease of newborns (HDN) is one of the most significant risk factors for hyperbilirubinemia. Studies have shown that end-tidal carbon monoxide-corrected (ETCOc) correlated with the rate of bilirubin production in the body and thus can be a good surrogate to quantify hemolysis and identifying the high-risk infants. However, …
Serum Estradiol (E2) Levels in Breast Cancer Patients During Endocrine Therapy by High Performance Liquid Chromatography-tandem Mass Spectrometry (LC-MS /MS)
The investigators intend to conduct a prospective cohort study to detect E2 levels during endocrine therapy in Chinese breast cancer patients using LC-MS/MS methods, and to determine the proportion of patients with premenopausal E2 levels (OFR or E2 insufficiency) during AIs or FUL endocrine therapy. To further explore the correlation …
AI-Assisted System for Accurate Diagnosis and Prognosis of Breast Phyllodes Tumors
Breast phyllodes tumor (PT) is a rare fibroepithelial tumor, accounting for 1% to 3% of all breast tumors, categorized by the WHO into benign, borderline, and malignant, based on histopathology features such as tumor border, stromal cellularity, stromal atypia, mitotic activity and stromal overgrowth. Malignant PTs account for 18%-25%, with …
A Real-world Study on the Treatment of Non-small Cell Lung Cancer With Leptomeningeal Metastasis in China
This is a retrospective and prospective study planned to include NSCLC patients with Leptomeningeal metastasis (LM) and treated with antitumor therapy after 2018, from multiple centers such as the First Affiliated Hospital of Guangzhou Medical University, Guangdong Sanjiu Brain Hospital, etc., aiming to establish a database related to the treatment …
Chronic Airway Disease and Multimorbidity Cohort
Background: Chronic airway diseases (CAD), including chronic obstructive pulmonary disease (COPD), asthma and bronchiectasis, are highly prevalent and cause serious disease burden. Multimorbidity is recognized to influence treatment decision and prognosis of patients with stable CAD. The impact of multimorbidity on exacerbation CAD is under investigated. Methods: The Chronic Airway …
Regional Radiotherapy Omission in Low-Risk Node Positive Breast Cancer
The purpose of this study is to determine whether certain patients can safely omit regional lymph node radiotherapy. These women must have hormone-sensitive, Her2-negative tumors, have 1-3 positive axillary nodes and have RecurIndex low-risk.
AI Recognition of Important Structures in Otolaryngological Surgery
Developing a system for artificial intelligence to recognize anatomical landmarks in otolaryngological surgery, enabling real-time tracking of critical temporal bone structures during surgery.
