Role of the collagen scaffold in preventing intrauterine adhesion from recurrence after adhesiolysis: protocol for a multicentre, randomised, controlled, parallel-group, open-label, superiority clinical trial.

Introduction: Intrauterine adhesions (IUAs) are one of the most common causes of uterine infertility. Hysteroscopic adhesiolysis is the primary treatment for IUA, but the rate of IUA recurrence is high in moderate to severe cases. While traditional guidelines recommend placing a non-copper stainless steel intrauterine device (IUD) into the uterine cavity after adhesiolysis to prevent readhesion, the preventive effect is uncertain.

Identification of syncytiotrophoblast-derived cf-RNA OPA1 to predict the occurrence of preeclampsia.

Background: Pre-eclampsia (PE) poses a significant threat to mothers and infants worldwide. Studies indicate that taking low-dose aspirin before the 16th week of pregnancy may prevent approximately 70 % of PE cases, highlighting the importance of predicting PE. Cell-free RNA (cf-RNA) exhibits significant changes in the maternal peripheral blood during early pregnancy, making cf-RNA analysis a promising and less invasive method for predicting PE.

Prediction model of preeclampsia using machine learning based methods: a population based cohort study in China.

Introduction: Preeclampsia is a disease with an unknown pathogenesis and is one of the leading causes of maternal and perinatal morbidity. At present, early identification of high-risk groups for preeclampsia and timely intervention with aspirin is an effective preventive method against preeclampsia. This study aims to develop a robust and effective preeclampsia prediction model with good performance by machine learning algorithms based on maternal characteristics, biophysical and biochemical markers at 11-13 +  weeks' gestation, providing an effective tool for early screening and prediction of preeclampsia.

External validation of the modified CTP score based on ammonia to predict survival in patients with cirrhosis after TIPS placement.

This study aimed to perform the first external validation of the modified Child-Turcotte-Pugh score based on plasma ammonia (aCTP) and compare it with other risk scoring systems to predict survival in patients with cirrhosis after transjugular intrahepatic portosystemic shunt (TIPS) placement. We retrospectively reviewed 473 patients from three cohorts between January 2016 and June 2022 and compared the aCTP score with the Child-Turcotte-Pugh (CTP) score, albumin-bilirubin (ALBI), model for end-stage liver disease (MELD) and sodium MELD (MELD-Na) in predicting transplant-free survival by the concordance index (C-index), area under the receiver operating characteristic curve, calibration plot, and decision curve analysis (DCA) curve. The median follow-up time was 29 months, during which a total of 62 (20.

The effect of different flushing and locking techniques on catheter occlusion rates in central venous catheters: protocol for a multicentre, randomized controlled, parallel-group, open-label, superiority clinical trial.

Background: Maintaining venous access is of great clinical importance. Running a slow continuous infusion to keep the vein open (KVO) is often used in peripheral intravenous catheters (PIVCs). Previous studies have compared the effects of intermittent flushing and continuous infusion via peripherally inserted central catheters (PICCs).

Histological evaluation of pyrrolizidine alkaloid-induced hepatic sinusoidal obstruction syndrome: Correlation with Drum Tower Severity Scoring.

Background: Hepatic sinusoidal obstruction syndrome induced by pyrrolizidine alkaloids (PA-HSOS) is a complication of drug-induced liver damage. Few studies have examined the relationship between pathological changes and clinical circumstances in PA-HSOS. The Drum Tower Severity Scoring System (DTSS) was developed using prognostic indicators from clinical treatment outcomes.

Effect of autologous bone marrow stem cells-scaffold transplantation on the ongoing pregnancy rate in intrauterine adhesion women: a randomized, controlled trial.

Intrauterine adhesion is a major cause of female reproductive disorders. Although we and others uncontrolled pilot studies showed that treatment with autologous bone marrow stem cells made a few patients with severe intrauterine adhesion obtain live birth, no large sample randomized controlled studies on this therapeutic strategy in such patients have been reported so far. To verify if the therapy of autologous bone marrow stem cells-scaffold is superior to traditional treatment in moderate to severe intrauterine adhesion patients in increasing their ongoing pregnancy rate, we conducted this randomized controlled clinical trial.

The clinical data of patients were statistically compared and the nomogram was constructed based on the results of multivariate logistic regression analysis and stepwise (stepAIC) selection.

Self-Reported adverse events among Chinese healthcare workers immunized with COVID-19 vaccines composed of inactivated SARS-CoV-2.

Mass vaccination is critical to control the pandemic of coronavirus disease 2019 (COVID-19). Fear of adverse events (AEs) after COVID-19 vaccination is a main factor associated with vaccination hesitancy. We aimed to analyze AEs in healthcare workers (HCWs) vaccinated with COVID-19 vaccines (Aikewei or CoronaVac) composed of inactivated virus.

Development of a Drum Tower Severity Scoring (DTSS) system for pyrrolizidine alkaloid-induced hepatic sinusoidal obstruction syndrome.

Background And Aims: There has been no reliable severity system based on the prognosis to guide therapeutic strategies for patients with pyrrolizidine alkaloid (PA)-induced hepatic sinusoidal obstruction syndrome (HSOS). We aimed to create a novel Drum Tower Severity Scoring (DTSS) system for these patients to guide therapy.

Methods: 172 Patients with PA-HSOS who received supportive care and anticoagulation therapy in Nanjing Drum Tower Hospital from January 2008 to December 2020 were enrolled and analyzed retrospectively.

Comparison of Two Bayesian Methods in Evaluation of the Absence of the Gold Standard Diagnostic Tests.

Objective: The Bayesian model plays an important role in diagnostic test evaluation in the absence of the gold standard, which used the external prior distribution of a parameter combined with sample data to yield the posterior distribution of the test characteristics. However, the correlation between diagnostic tests has always been a problem that cannot be ignored in the Bayesian model evaluation. This study will discuss how different Bayesian model, correlation scenarios, and prior distribution affect the outcome.
