Effectiveness, safety, and acceptability of postplacental insertion of GyneFix postpartum intrauterine device among women undergoing cesarean section: A multicenter prospective cohort study in China.

Objectives: To assess the effectiveness, safety, and acceptability of postplacental insertion of GyneFix postpartum intrauterine device (PPIUD) in women undergoing cesarean section (C-section).

Study Design: We conducted a prospective cohort study at 14 hospitals in four eastern coastal provinces of China between September 2017 and November 2020. A total of 470 women who underwent C-section and consented to the postplacental insertion of GyneFix PPIUD were enrolled, and 400 completed the 12-month follow-up.

Associations between Gene-Gene Interaction and Overweight/Obesity of 12-Month-Old Chinese Infants.

Background: Childhood overweight and obesity (OW/OB) is a worldwide public health problem, and its genetic risks remain unclear.

Objectives: To investigate risks of OW/OB associated with genetic variances in rs543874 and rs10913469, rs11030104 and rs6265, rs11191580, rs11165675, rs2531995, rs7869969, rs2237892, and rs2968990 in Chinese infants at 12-month old.

Methods: We conducted a case-control study with 734 infants included at delivery and followed up to 12-month old.

Effect of maternal glycemia and weight status on offspring birth measures and BMI-z among Chinese population in the first year.

To investigate the effects of maternal fasting plasma glucose (FPG) and pre-pregnancy weight status (PPWS) on offspring birth measures and body mass index z-score (BMI-z) in the first year, we conducted a prospective study of 1,096 mother-infant dyads in Guangdong, China, 2014-2015. Multivariate logistic regression was used to test independent/interaction associations of maternal FPG and PPWS with macrosomia/large for gestational age (LGA). Association of PPWS and FPG with offspring BMI-z in the first year was assessed by the linear mixed effects models.

A Morphometric Study of the Newborn Ear and an Analysis of Factors Related to Congenital Auricular Deformities.

Background: The incidence of neonatal ear deformities varies widely in the literature, and the incidence of those that correct spontaneously is largely unknown. To address these questions, the authors analyzed the auricles of 1500 newborns from the Pearl River Delta within the first 7 days of life and again at 30 days of age.

Methods: Using a combination of direct measurement and digital image measurement, the authors measured physiognomic ear length, physiognomic ear breadth, morphologic ear length, vertical distance between head and ear, and auriculocephalic angle of the newborns.
