New screening approach to detecting congenital syphilis in China: a retrospective cohort study.

Background: Diagnosis of congenital syphilis (CS) is not straightforward and can be challenging. This study aimed to evaluate the validity of an algorithm using timing of maternal antisyphilis treatment and titres of non-treponemal antibody as predictors of CS.

Methods: Confirmed CS cases and those where CS was excluded were obtained from the Guangzhou Prevention of Mother-to-Child Transmission of syphilis programme between 2011 and 2019.

[Neuropsychological development of late preterm infants and early term infants at the age of 1 year: a follow-up study].

Objective: To study the level of neuropsychological development in late preterm infants and early term infants at the age of 1 year.

Methods: A total of 1 257 children with a corrected age of 1 year were enrolled as subjects. According to gestational age at birth, they were divided into an early preterm group (28-33 weeks), a late preterm group (34-36 weeks), an early term group (37-38 weeks), and a full-term group (39-41 weeks).

The Effect of Different Treatment Regimens and Multiple Risk Factors on Adverse Pregnancy Outcomes among Syphilis-Seropositive Women in Guangzhou: A Retrospective Cohort Study.

Background: To eliminate mother-to-child transmission of syphilis, the Chinese government recommends a treatment regimen that slightly differs from the World Health Organization- (WHO-) recommended treatment. However, little is known about their difference in efficacy. This study is aimed at comparing the effect of China-recommended and WHO-recommend treatment regimens on adverse pregnancy outcomes (APOs) and at examining associated risk factors of APOs among syphilis-seropositive women.

Effects of Antiretroviral Therapy and HIV Exposure in Utero on Adverse Pregnancy and Infant Outcomes: A Prospective Cohort Study in Guangzhou, China.

Effectiveness of a Kindergarten-Based Intervention for Preventing Childhood Obesity.

Background And Objectives: Interventions to prevent childhood obesity targeting school age children have mostly reported limited effectiveness, suggesting such prevention programs may need to start at an earlier age, but evidence has been scarce. We reported a pilot study aiming to demonstrate the feasibility of a multifaceted intervention for preschool children and to provide a preliminary assessment of the effectiveness.

Methods: This nonrandomized controlled trial recruited children aged 3 to 6 years from 6 kindergartens in Guangzhou, China.
