Objective: To investigate the clinical characteristics, treatment strategies, and outcomes of very low birth weight (VLBW)/extremely low birth weight (ELBW) preterm infants in Weihai from January 2017 to December 2019.
Methods: 107 VLBW/ELBW preterm infants admitted to our hospital were recruited as the study cohort and divided into three groups: the < 1000 g group (n = 11 cases), the ≥ 1000~1250 g group (n = 32 cases), and the ≥ 1250~1500 g group (n = 64 cases). The clinical characteristics of the VLBW/ELBW preterm infants in each group were analyzed, and the hospitalization duration times, the survival rates, the ventilator use, the main complications, and the follow-ups in each group were compared statistically.
Results: There were significant differences in the occurrences of maternal anemia during pregnancy, the birth weights, the gestational ages, the births of singletons, twins, or multiples, the hospitalization duration times, the occurrences of late-onset sepsis (LOS), and the occurrences of periventricular intraventricular hemorrhages (PIVH) among the three groups (P < 0.05). Our multivariate logistic regression and ROC curve analyses showed that the lower the gestational age (OR = 12.56, 95% CI: 2.45~14.63, P = 0.01), the lower the birth weight (OR = 8.69, 95% CI: 1.95~10.34, P = 0.03), and the premature rupture of membranes (OR = 6.44, 95% CI: 1.03~9.77, P = 0.04) and LOS (OR = 9.64, 95% CI: 1.67~18.99, P = 0.02) would induce a higher death rate among premature infants. Furthermore, after one year of follow-up, the psychomotor development indexes (PDI) of the different birth weight groups were increased along with the birth weight, and the differences were statistically significant (χ = 4.19, 4.99, P = 0.027, 0.01).
Conclusion: Strengthening perinatal health care and actively preventing and treating various complications are of great significance in improving the survival rate and long-term quality of life of VLBW/ELBW premature infants.

Objectives: Sickle cell disease (SCD), which disproportionately affects minorities, increases complications during pregnancy. Severe maternal mortality is increased in women with SCD, including morbidity related to the disease and other nondisease-related complications. It also can have devastating complications for fetuses, with increases in premature birth and low birth weight.

Introduction And Hypothesis: This study aims to develop a postpartum stress urinary incontinence (PPSUI) risk prediction model based on an updated definition of PPSUI, using machine learning algorithms. The goal is to identify the best model for early clinical screening to improve screening accuracy and optimize clinical management strategies.
Methods: This prospective study collected data from 1208 postpartum women, with the dataset randomly divided into training and testing sets (8:2).
Purpose: To assess the association between periodontal health and pregnancy or delivery complications in type 1 diabetic (TIDM) and non-diabetic pregnant women.
Materials And Methods: 15 TIDM and 15 non-diabetic primiparous women were enrolled in the prospective case-control study. We compared periodontal status, levels of glycosylated hemoglobin (HbA1c), gestational week of birth, birth weight of a newborn and pregnancy or delivery complications between the groups.

Breast milk (BM) is the only source of iodine and bioactive compounds that influence growth and development in infants. The content of BM may be influenced by maternal body mass index (BMI). The aim of this study was to investigate the effect of maternal weight on BM and cord blood iodine concentrations, growth-related hormones, infant anthropometric measurements.
