Clinical trials

Adverse pregnancy outcomes (APOs) are a collection of conditions that have short-term and long-term effects of complications related to pregnancy and childbirth on pregnant women and their fetuses, including hypertensive disorders of pregnancy, gestational diabetes, preterm birth, large for gestational age, among others. Nearly 30% of all women experience an adverse pregnancy outcome during their reproductive years. Although, respiratory viral infections with epidemic and pandemic potential pose an omnipresent threat to public health, research focusing specifically on the maternal-infant population remains relatively scarce. Studies conducted in USA found that among pregnant women infected with influenza, the proportion of those with gestational hypertension or diabetes was higher than in pregnant women without influenza infection (13.9% vs. 11.1%). Research on the impact of respiratory viral infections on perinatal outcomes in China is limited, and we aim to establish of a large-scale, retroprospective maternal-child cohorts. This cohort study will systematically collect longitudinal data (e.g., detailed clinical history, timing of infection/vaccination, complication of pregnancy, and APOs) to assess the risk of respiratory viral infections to APOs, as well as facilitate multidisciplinary research.

Monitoring of antimicrobial resistance (AMR) based on metagenomics analyses in pneumonia patients is critical for optimizing clinical diagnosis and treatment and improving clinical prognosis. This study is designed to ask the following key questions: 1. What is the microbiome maps of patients with severe pneumonia and mild pneumonia ? 2. How many pathogen resistance genes are carrying in severe pneumonia and mild pneumonia ? 3. What is the genetic diversity of key pathogens detected in severe pneumonia and mild pneumonia during 2019-2025?

Objective: 1. To systematically screen the high-risk population of diabetes in Xinqiao area, understand the characteristics of early glucose metabolism changes and pancreatic islet function changes in the high-risk population and patients with prediabetes, and establish the first standardized research cohort of high-risk patients and prediabetes patients in Songjiang area. 2\. Use CGM monitoring technology to identify the high-risk groups of diabetes and the fluctuation of blood glucose in pre-diabetes, understand their ophthalmology and bone density, observe the annual conversion rate of diabetes, find effective interventions, move forward the management of diabetes, and create a new model for the management of high-risk groups of diabetes. Research content: Part I: Establishing the first standardized diabetes high-risk population research cohort in Songjiang area The initiative focuses on early screening for high-risk populations with diabetes, shifting the focus downward and advancing prevention measures to detect diabetes at an earlier stage and initiate timely intervention. In Xinqiao District, all high-risk screening cases will undergo medical history documentation, anthropometric measurements, laboratory testing, and regular follow-ups. Standard oral glucose tolerance test (OGTT) methods will be employed to assess fasting blood glucose levels, insulin sensitivity, 2-hour postprandial glucose and insulin levels after a 75g glucose load, and glycated hemoglobin levels. Beyond evaluating glucose metabolism, the screening will also detect other metabolic disorders through routine blood tests including urinalysis, liver/kidney function tests, uric acid levels, lipid profiles, thyroid function, and urine protein/creatinine ratio. The establishment of this premium high-risk screening program in Xinqiao Community will create Songjiang District's first standardized research cohort for diabetes mellitus (DM) and prediabetes patients, carrying significant strategic importance. Part II: By integrating Clinical Monitoring (CGM) technology with ophthalmological evaluations and bone density ultrasound examinations, we identify characteristics of high-risk diabetic populations and track their disease progression. The CGM system (with auxiliary devices such as the Shansheng Dynamic Glucose Monitoring System) is utilized to monitor blood glucose fluctuations in these individuals. Concurrently, comprehensive ophthalmic assessments-including visual acuity tests, intraocular pressure measurements, fundus photography, OCT scans, OCTA imaging, and SLO examinations-are conducted alongside bone density testing. Annual follow-up evaluations are performed to track clinical outcomes. Research innovation points and expected results: Research innovation points: Establish the first standardized research cohort of high-risk and pre-diabetic patients in Songjiang area; move forward the management of diabetes, and create a new management model for high-risk groups of diabetes. anticipated results 1. Establish a new standardized diabetes high-risk population research cohort with large sample size. 2. Observe the metabolic characteristics, blood glucose fluctuation, ophthalmic conditions and bone density of high-risk groups with diabetes. 3. Find effective interventions to reduce the annual conversion rate of diabetes.

Establish a high-quality clinical cohort of hyperglycemia in pregnancy. Develop subtype-specific, end-to-end standards for diagnosis, treatment, and follow-up across the preconception, pregnancy, and postpartum phases. These standards will lay a solid foundation for efficient, high-quality clinical research.

To explore the relationship between genetic factors, lifestyle, and drug interventions and the occurrence, development, adverse pregnancy outcomes, and postpartum maternal-infant outcomes of gestational endocrine diseases.
