ABSTRACT

Objective:To investigate the relationship between adiponectin (ADIPOQ) gene polymorphism and postpartum type 2 diabetes mellitus (T2DM) in pregnant women with gestational diabetes mellitus (GDM).Methods:A retrospective study was conducted on 236 GDM postpartum women admitted to the Affiliated Hospital of Jining Medical College from June 2020 to June 2021 as observation subjects. They were divided into a T2DM group and a non T2DM group based on the occurrence of T2DM after delivery. The clinical data of the two groups were compared. The double deoxygenation end termination method was used to detect the single nucleotide polymorphism (SNP) of the ADIPOQ gene, and the four loci rs17366568, rs822395, rs1501299, and rs2241766 were classified. The relationship between ADIPOQ genotype polymorphism and postpartum T2DM was analyzed using a logistic regression model.Results:The G allele carrying the rs2241766 locus in ADIPOQ gene was negatively correlated with the occurrence of T2DM ( OR=0.71, 0.68, P<0.05). Compared with T2DM patients with TT genotype, the GT+ GG genotype at the rs2241766 locus had a lower risk of occurrence for gestational age ≥2 and HbA 1c>85%. Similarly, T2DM patients with pre pregnancy body mass index (BMI)>25 kg/m 2 were more likely to be carriers of the rs2241766 TT genotype ( P=0.026). The (GT+ TT) genotype carrying the T allele at the rs1501299 locus was a protective factor for gestational age and HbA 1c in T2DM patients. Conclusions:The rs2241766 and rs1501299 polymorphisms of the ADIPOQ gene are associated with susceptibility to postpartum T2DM in GDM women. Individuals with rs2241766 and rs1501299 mutant genotypes belong to the high-risk population for T2DM.

ABSTRACT

Objective:To analyze the impact of adolescent pregnancy on maternal and infant outcomes.Methods:A retrospective cohort study was conducted on 5 765 parturbirths in Jining Medical College Hospital from January 1, 2019 to December 31, 2020. The parturbirths were divided into adolescent group (maternal age<20 years, 280 cases), age group 1 (maternal age 20-24 years, 1 733 cases) and age groups 2 (maternal age 25-34 years, 3 752 cases). All information was collected through the hospital′s electronic case system. General data, pregnancy characteristics and outcomes were compared among the three groups by analysis of variance (ANOVA), χ 2 tests and binary logistics regression analysis was used to analyze the impact of adolescent pregnancy on maternal and infant outcomes. Results:In the adolescent group, the proportion of women with an education of junior high school or below, rural residence, no fixed income, unmarried, and no history of induced abortion were all significantly higher than those in age group 1 and age group 2 (82.50% vs 17.37%, 14.37%; 59.29% vs 42.70%, 43.36%; 80.71% vs 15.52%, 14.71%; 75.71% vs 12.23%, 9.97%; 82.50% vs 71.84%, 71.91%) (all P<0.05); there was no significant differences in age at menarche, body mass index before pregnancy, and weight gain during pregnancy among the three groups (all P>0.05). The proportion of preterm birth, low birth weight infants and transferring to neonatal intensive care unit (NICU) in the adolescent group were all significantly higher than those in age group 1 and age group 2 (5.36% vs 1.10%, 1.57%; 5.00% vs 0.23%, 0.05%; 21.79% vs 6.12%, 15.17%); the incidence of anemia in pregnancy in the adolescent group was significantly higher than that in age group 1 (15.36% vs 9.75%), and the incidence of postpartum hemorrhage was significantly higher than that in the age group 2 (10.71% vs 6.08%). The incidence of failed vaginal trials leading to cesarean section, amniotic fluid contamination, and episiotomy was significantly lower in the adolescent group than those in age group 2 (8.57% vs 15.22%, 10.71% vs 18.10%, 33.95% vs 40.01%) (all P<0.05). The incidence of failed vaginal trials leading to cesarean section was inversely associated with gestational age (adolescent group, OR=0.252, 95% CI: 0.123-0.515; age group 1, OR=0.673, 95% CI: 0.567-0.799) (both P<0.05); the risks of low birth weight infants (adolescent group, OR=7.440, 95% CI: 3.426-16.156; age group 1, OR=0.103, 95% CI: 0.032-0.330) and transferring to the NICU (adolescent group, OR=1.661, 95% CI: 1.120-2.463; age group 1, OR=0.360, 95% CI: 0.290-0.448) showed a U-shaped distribution in different pregnancy age groups, they were both higher in the adolescent group than those in the age group 2 (both P<0.05); the risk of episiotomy (adolescent group, OR=0.002, 95% CI: 0-0.016; age group 1, OR=1.308, 95% CI: 1.151-1.485) showed an inverted U-shape distribution across the different pregnancy age groups, it was lower in the adolescent group than that in age group 2 (both P<0.05). Conclusion:Adolescent pregnancy is associated with a lower risk of conversion to cesarean section and episiotomy due to failed vaginal delivery, but may increase the risk of low birth weight infants and transferring to NICU.

ABSTRACT

Objective:To construct and validate a prediction model for the risk of intermediate cesarean delivery for primiparous women with failed vaginal trial of labor.Methods:Clinical data of 6 128 pregnant women who gave birth in the Affiliated Hospital of Jining Medical College from January 2019 to December 2020 were collected. The puerpera was randomly divided into train set ( n=4 290) and validation set ( n=1 838). The factors influencing the conversion to cesarean section in primiparous women with failed vaginal trial of labor were analyzed with univariate and binary multivariate logistic regression, and a risk prediction model was established based on the influencing factors. The predictive power of the model was assessed by receiver operating characteristic (ROC) curve and the Hosmer-Lemeshow goodness-of-fit test in train set and validation set. Results:Among 6 128 pregnant women 1 042 cases failed in vaginal trial of labor and were transferred to cesarean section. Univariate analysis showed age, occupation, gestational weight gain, days of gestation, body temperature before delivery, fetal heart condition at delivery, fetal abdominal circumference, Bishop score, premature rupture of membranes, gestational illness, mode of induction of labor, labor analgesia, and fetal orientation were significantly associated with converting to cesarean delivery (all P<0.05). The multivariate binary logistic regression analysis showed that the age, gestational weight gain, body temperature, gestational co-morbidities, days of gestation, premature rupture of membranes, amniotic fluid contamination, induction of labor, and abnormal occipital position were independent risk factors for intermediate cesarean delivery ( OR=1.03-8.06, all P<0.05); while height, occupation, Bishop score, and labor analgesia were protective factors for intermediate cesarean delivery ( OR=0.17-0.96, all P<0.05). A risk prediction model was constructed based on the risk factors and protective factors. In train set, the area under the ROC curve(AUC) of the model was 0.902 (95% CI: 0.89-0.92, P<0.001), with the best cutoff value of 0.138, the sensitivity and specificity were 0.837 and 0.825, respectively; and the Hosmer-Lemeshow goodness-of-fit test showed P=0.192. In validation set the AUC of the model was 0.917 (95% CI: 0.90-0.93, P<0.001), and the sensitivity and specificity were 0.826 and 0.851, respectively; the total correct rate of the model was 87.21% (1 603/1 838). Conclusion:The risk prediction model of failed vaginal trial of labor in primiparous women for intermediate cesarean delivery constructed in this study has good clinical prediction efficacy and high correctness rate.

ABSTRACT

Objective:To investigate the current status of women′s level of birth experience and lactation initiation time and explore the effect of level of birth experience on lactation initiation time.Methods:This was a cross-sectional study. A convenience sampling method was used to select 622 maternal cases attending the Affiliated Hospital of Jining Medical College from November, 2020 to January, 2021, and the distribution of their labor experience level and lactation initiation time was investigated by questionnaire and follow-up assessment.Results:There were 622 women with transvaginal deliveries who had lactation initiation times of more than 72 h in 241 cases (38.75%). The scores for each dimension of the Childbirth Experience Questionnaire (CEQ) were (49.63 ± 8.58)points, and the scores for each dimension of CEQ were perceived safety, professional support, involvement and self-efficacy in descending order. The results of the correlation analysis showed that there was a negative correlation between the scores on each dimension of CEQ and the total score and lactation initiation time ( r values were -0.436 to -0.146, all P<0.01). Stratified regression analysis showed that after controlling for age, number of births, gestational weeks of labour, illness during pregnancy and labour analgesia as the underlying variables affecting lactation initiation time, the scores for self-efficacy, involvement, perceived safety and professional support in the CEQ all affected lactation initiation time after delivery ( t values were -6.76 to -2.02, all P<0.05). Conclusions:The birth experience and lactation of women who deliver via vaginal birth need to be taken into account. The more negative the birth experience, the longer the lactation initiation time. The women′s involvement in the birth process, their own competence, perceived safety and level of professional support are all valid influencing indicators of lactation initiation time.

ABSTRACT

The incidence of prostate cancer has shown an obvious upward trend in recent years.18F-fluorodeoxyglucose(FDG)is a broad-spectrum imaging agent for cancer,but there is a " blind zone" in the application of prostate cancer.Therefore,exploring prostate imaging agents with better performance can help to make up the deficiency.At present,there are a number of positron imaging agents for prostate cancer,but the overall advantage is not obvious.Recently,a new imaging agent,68Ga-prostate specific membrane antigen(PSMA),has been demonstrated its better value in clinical application of prostate cancer.This review summarizes the research progress of 68 Ga-PSMA,
