Building a machine learning-based risk prediction model for second-trimester miscarriage.

Background: Second-trimester miscarriage is a common adverse pregnancy outcome that imposes substantial economic and psychological pressures on both the physical and mental well-being of patients and their families. Currently, there is a scarcity of research on predictive models for the risk of second-trimester miscarriage.

Methods: Clinical data were retrospectively collected from patients who were in the second trimester of pregnancy (between 14+0 and 27+6 weeks gestation), whose main diagnosis was "threatened abortion" and who were hospitalized at the Women and Children's Hospital of Ningbo University from January 2020 to October 2023.

Establishment of a predictive model for postpartum hemorrhage in twins: a retrospective study.

Objective: To explore the risk factors and develop a predictive model for postpartum hemorrhage in twin pregnancies.

Methods: All patients who gave birth at Ningbo Women and Children's Hospital from January 2018 to August 2022 were recruited. Patients were randomly allocated to a training cohort (n[Formula: see text]1395) validation cohort (n[Formula: see text]650) at a 7:3 ratio.

Application of the Plan-Do-Check-Act Cycle in Shortening the Decision to Delivery Interval Time.

Objective: To discuss the application value of the plan-do-check-act (PDCA) cycle in shortening the decision to delivery interval (DDI) time.

Methods: A total of 106 DDI cases from the Ningbo Women and Children's Hospital (China) from January 2019 to December 2020 were selected as the subjects of this study. The causes for the prolongation of DDI were analyzed and protocols were developed.

The Clinical Significance and Biological Function of in Cervical Cancer.

Purpose: Cervical cancer is a common cancerous tumor in women that is prone to recurrence and metastasis. Recently, many people have explored the role of protocadherin 7 () in cancer and found that is abnormally expressed in many cancers. The purpose of this study is to explore the expression and mechanism of in cervical cancer and evaluate its clinical prognostic significance.

Uterine Massage to Reduce Blood Loss Before Delivery of the Placenta in Caesarean Section: A Retrospective Cohort Study.

Background/objective: To estimate the effectiveness of uterine massage UM in reducing blood loss before delivery of placenta in CS.

Methods: This was a retrospective cohort study of 1393 women who delivered with CS. Patients who underwent UM (671women) were compared with those who underwent controlled cord traction (722 women).

Comparison of expression of growth hormone-releasing hormone and its receptor splice variant 1 in different stages of endometriosis.

Background: The present study aims to explore the significance of the expression of growth hormone-releasing hormone (GHRH) and its receptor splice variant 1 (GHRHSV1) in endometriosis (EM).

Materials And Methods: In this research paper 80 EM patients who received treatment between March 2009 and September 2010 were selected, among which 20 were in stages I, II, III and IV respectively. 50 non-EM patients who underwent hysterectomy because of myoma during the same period comprised the control group.
