Assessment of Eyelid Topology and Kinetics Based on Deep Learning Method
This study plans to assess eyelid topology (such as margin reflex distance, eyelid contour, and corneal exposure area) and blinking (such as frequency, velocity, and duration), using deep learning method to automatically extract eyelid topological features, and to predict subtypes of levator function, using deep learning method to extract blinking …
Efficacy of Hepatitis B Vaccine Boosters Among Neonatally Vaccinated Children in Chongqing
Worldwide, hepatitis B virus (HBV) infection is a major cause of acute hepatitis, and chronic infection with HBV often leads to chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. So far, the most effective way to prevent HBV infection in susceptible population is to inject hepatitis B vaccine. However, long-term protection …
Influence of Pupillary Behavior During Eye Surgery on Morphological and Functional Outcome
Pupillary movement during eye surgery can be a challenge for eye surgeons. Despite the risk of intraocular lens damage and malpositioning due to mechanical manipulation1, iris manipulation may lead to a significant elevation of cytokines in the aqueous humor and an increase of postoperative inflammation2, 3. Iris damage is also …

SEC test prior surgery (with middle ear fluid) and at 1 month control visit (dry middle ear with ventilation tube). Otitis media 6 questionnaire prior surgery and at the 1 month …
Development and Validation of a Screening Score for the Biliary Atresia in Infantile Cholestasis: A Prospective Study
Better survival and prognosis of biliary atresia (BA) depend on early diagnosis and timely Kasai portoenterostomy. Identifying BA from other causes of infantile cholestasis at early stage of the disease still remains a major challenge. In this study, the investigators aim to develop and validate a scoring system to screen …
Cognitive Impairment and Fatigue After Mild to Moderate COVID-19
The primary aim of the project is to map fatigue, cognitive and visual dysfunctions and possible underlying pathophysiological mechanisms in persons with long-term symptoms after a mild to moderate COVID-19 infection. Secondary goals are to study whether covarying factors such as depression and sleep disorders contribute to the results.
The Role of Cardiac Mechanics, Biomarkers and Frailty in Aortic Stenosis
The role of cardiac mechanics, circulating biomarkers and frailty in predicting outcomes in patients with aortic stenosis after aortic valve replacement (SCRABLES -The 2-Parts Study) Part I: Observational study to characterize phenotypes, structural alterations and biomarkers profiles in a broad spectrum of patients with aortic stenosis and heart failure with …
The Impact of Excessive Dietary Sodium on Brain Health
Sporadic cerebral small vessel disease (CSVD) is not only the most common subtype of vascular dementia, in recent multi-center study showed that sporadic CSVD harbors in a third of Alzheimer's disease (AD) patients in 9 Asian regions. The CSVD increases the severity of cognitive impairment in these patients and has …

Purpose The primary objective of the study is to compare interpretation of EUS FNA/FNB samples for adequacy between ROSE and AI at bedside. To compare accuracy of preliminary diagnosis results between ROSE and AI at bedside versus final pathology report. Research design This is a prospective single center study to …
The Theranostic Value of STARD3 in Colorectal Cancer: The STAR Study
This study aims at verifying the overexpression of STARD3 in both early and advanced CRC patients derived tissues, to identify the pathways underpinning tumorigenesis and cancer progression in which STARD3 is involved. Moreover its role as a dynamic biomarker of treatment response and its part in treatment sensitivity will be …
