ABSTRACT

Background There is a lack of research evidence on the association between sugar-sweetened beverage (SSB) consumption and gestational diabetes mellitus (GDM) in China. Objective To explore the association between frequency of SSB consumption before pregnancy and risk of GDM in pregnant women in Shaanxi Province, and to provide a scientific basis for targeted interventions to control maternal blood glucose. Methods The recruitment to the China Birth Cohort study started in October 2020. Pregnant women at 6-16 weeks who had their first prenatal examination at five hospitals in Shaanxi Province were recruited. A maternal health questionnaire was used to collect basic information about pregnant women. A semi-quantitative food frequency questionnaire was used to collect the consumption of carbonated beverages, fruit and vegetable juice beverages, coffee beverages, and milk tea beverages in one year before pregnancy, which were summed to obtain the SSB consumption. Pregnant women were divided into three groups according to SSB consumption, namely <1 serving·week−1, 1-4 servings·week−1, and ≥5 servings·week−1. GDM was confirmed by oral glucose tolerance test (OGTT) between 24-28 weeks of gestation. A binary logistic regression model was applied to explore the association between SSB consumption and risk of GDM. Multiple linear regression was applied to investigate the associations between SSB consumption (per 1-serving·d−1 increase) and OGTT fasting plasma glucose, 1-hour glucose, and 2-hour glucose. Results A total of 3811 pregnant women were finally enrolled in this study, of which 752 developed GDM, with an incidence rate of 19.7%. The incidence rates of GDM in pregnant women with SSB consumption frequency of <1 serving·week−1, 1-4 servings·week−1, and ≥5 servings·week−1 were 18.0%, 21.1%, and 26.8%, respectively. After adjusting for maternal age, pre-pregnancy body mass index (BMI), education, number of children born, family history of diabetes, smoking, alcohol consumption, physical activity level, and total energy intake, the risk of GDM increased by 26% (OR=1.26, 95%CI: 1.05, 1.50) in the 1-4 servings·week−1 group and by 76% (OR=1.76, 95%CI: 1.31, 2.38) in the ≥5 servings·week−1 group compared to the <1 serving·week−1 SSB consumption group, respectively. Further stratified analysis revealed no interaction effect (Pinteraction>0.05) between SSB consumption and maternal age, pre-pregnancy BMI, or first labor or not. For each additional SSB consumption per day, the risk of GDM increased by 94% (OR=1.94, 95%CI: 1.37, 2.75); and the maternal OGTT 1-hour glucose and 2-hour glucose increased by 0.33 mmol·L−1 and 0.18 mmol·L−1, respectively (P<0.05), and no significant increase in fasting plasma glucose was found (P>0.05). Conclusion Higher SSB consumption before pregnancy increases the risk of GDM in pregnant women.

ABSTRACT

In view of the problems existing in the probation teaching of obstetrics and gynecology, such as patients' non-cooperation, few cases and few practical opportunities. This study discusses the application effect of case teaching based on "Rain Classroom" and standardized patients in the obstetrics and gynecology probation course. The teaching is carried out by carefully selecting cases, refining pre-class preparation, adopting various teaching forms, and carrying out evaluation after class. In order to evaluate the teaching effect, an anonymous survey was carried out among 330 undergraduate interns majoring in clinical medicine, prevention, and forensic medicine in Batch 2015. The results showed that 210 (93.8%) of 224 (67.9%) students who participated in the survey believed that this method could promote learning enthusiasm and 200 students (89.3%) thought it could activate classroom atmosphere more than traditional teaching; most students thought it improved students' communication ability (163, 72.8%), clinical practice ability (189, 84.4%), and ability to analyze and solve problems (171, 76.3%) and deepening the understanding, mastery and application of knowledge (158, 70.5%). It shows that this method can improve the teaching effect of obstetrics and gynecology probation course to a certain extent.

ABSTRACT

Objective:To analyze the correlation of fetal cervical cystic hygroma (CCH) with chromosomal and structural abnormalities and to assess the prognosis of CCH.Methods:This study retrospectively enrolled 70 fetuses with CCH diagnosed by prenatal ultrasound in the First Affiliated Hospital of Xi'an Jiao Tong University from July 2015, to December 2021. According to whether complicated by structural malformations or other anomalies, all the subjects were divided into the non-isolated and isolated CCH groups. The correlation of CCH and the gestational age at detection with chromosomal and structural abnormalities were analyzed and the prognosis of the cases were summarized using Chi-square test. Results:There were 34 isolated CCH (34/70, 49%) and 36 non-isolated CCH (36/70, 51%) among the 70 cases. In the non-isolated CCH group, there were eight cases (22%, 8/36) with abnormal heart structure, ten (28%, 10/36) with abnormal anterior abdominal wall, 16 (44%,16/36) with systemic edema and/or pleural effusion, one (3%,1/36) with craniocerebral abnormalities and one with holoprosencephaly and cardiac structural abnormalities. Eighteen out of 44 cases undergoing chromosome testing had chromosomal abnormalities, which were trisomy-18 ( n=6), trisomy-21 ( n=3), trisomy-13 ( n=3), 45,XO ( n=3), and chromosome segment duplication or deletion ( n=3). The detection rate of chromosome abnormality was higher in non-isolated CCH group comparing with isolated CCH group [59%(13/22) vs 23%(5/22), χ2=6.02, P=0.014]. There was no significant difference in the gestational age at the detection of CCH or proportion of women of advanced maternal age between the isolated and non-isolated CCH groups (both P>0.05). The ratios of isolated CCH cases with normal chromosome detected at the gestational weeks of 14-27 +6 was higher than those detected at 11-13 +6 weeks [62%(13/21) vs 17%(4/23), χ2=7.39, P=0.001]. Out of the 17 cases with isolated CCH and normal chromosomes, 12 were live births. One of the 12 cases still had a cystic mass with a diameter of 3 cm in the neck nine months after birth, and the other 11 cases had no mass at birth but one case died at the age of five months (hospitalized one week for neonatal edema),one case was found with anal atresia three days after birth and underwent operation and the remaining nine cases were normal during five months to six years follow-up. Conclusions:Non-isolated CCH is at a higher risk of chromosomal abnormalities. Isolated CCH cases detected later had higher rate of normal chromosome and often have a higher survival rate.

ABSTRACT

Objective To investigate the effect of case simulation and participatory feedback teaching used for neonatal resuscitation training. Methods One hundred and twenty medical staff was selected as subjects from Obstetric and Pediatric department and were randomized into 4 batches to receive a neonatal resuscitation training program that consisted of theoretical lectures and skill practice. In the control group (first two batches), the teacher demonstrated procedures of neonatal resuscitation, then trainees practiced alone and the teacher corrected their wrong procedure. In the observation group (last two batches), interactive teaching was employed and the training was performed into three steps:practice of skill in teams, watch the procedure of their practice, the feedback. The theoretical exami-nation score, practical examination score, teamwork ability and satisfaction were compared between two groups. SPSS 16.0 was employed for statistical analysis, with α=0.05 as detection level. Results The theoretical examination scores of control group and observation group were (34.27 ±2.26) vs. (33.68±2.32). There was no significant difference in theoretical examination score between the two groups ( P=0 . 166 ) . The practice examination score s of control group and observation group were (36.15±1.46) vs. (34.79±2.43), with significant differences (P=0.000). The teamwork ability of control group and observation group were (35.78 ±1.26) vs. (33.63 ±1.98), with obviously significant differ-ences (P=0.000). The trainees individual study interest, practice intent, knowledge and satisfaction with the training in the observation group were significantly higher than the control group. These results were (8.45±2.75) vs. (6.24±2.28), P=0.001;(8.25±2.05) vs. (6.48±2.75), P=0.003;(7.23±1.37) vs. (5.75 ±1.74), P=0.000; (8.21 ±1.45) vs. (6.34 ±1.69), P=0.000. Conclusion Application of the teaching in neonatal resuscitation training can enhance comprehensive practical skills and team coop-eration ability in med-ical staff, and it improves trainee's satisfaction with the training.

ABSTRACT

Objective Severe preeclampsia (sPE), which is usually complicated by small-for-gestational-age (SGA) and immature labor , remains a leading cause of maternal and neonatal mortality and morbidity. This study was to investigate the risk factors of SGA in sPE. Methods We retrospectively analyzed 100 cases of sPE, 35 with SGA (the case group) and the other 65 without it ( the control group ) .We conducted single-factor analysis on the general characteristics and potential impact factors of the patients , i-dentified the independent risk factors of SGA using the un-conditional stepwise logistic model , and assessed the value of umbilical arter-y S/D ratio and proteinuria ration in the diagnosis of sPE with SGA with the ROC curve . Results Compared with the control group , the case group had more cases of early-onset sPE ( P =0.010 ), earlier gestational and delivery weeks (P<0.001), lower neonatal weight at birth ( P<0 .001 ) , higher rate of admission to and longer stay in the neonatal ICU (P<0.001), and higher incidence of neo-natal complications (P<0.05).The case group also showed signifi-cant increases in comparison with the control in the umbilical artery S/D ratio (2.95 ±0.75 vs 2.31 ±0.47, P<0.05), frequency of S/D ratio ≥95th percentile (22.86% vs 6.15%, P<0.01), and rate of proteinuria ≥5 g/24 h (42.86% vs 20.00%, P<0.05).The S/D ratio ≥95th percentile (OR=6.02, 95%CI:2.32-16.78) and proteinuria≥5 g/24 h (OR=1.65, 95%CI:1.56-3.01) were found to be the risk factors of sPE with SGA.The area under the curve was 0.852 for the combination of S/D ra-tio and proteinuria ration in the diagnosis of sPE with SGA (P<0.05). Conclusion Umbilical artery S/D ratio≥95th percentile and proteinuria ≥5 g/24 h contribute to the early prediction, prevention, and prognosis of sPE, and is valuable for the diagnosis of sPE with SGA.
