地中海贫血孕妇产前诊断的护理效果评价

目的研究地中海贫血孕妇实施产科综合护理模式的护理配合措施及效果。方法选择78例于我院检查地中海贫血孕妇,纳入时间为2017年5月-2018年5月,采用随机数字表法将其分为综合护理组与对照组,每组均39例。其中对照组采用常规护理形式,综合护理组行产科综合护理模式,对比综合护理组与对照组护理前后心理状态评估指标及家属的护理满意度。结果护理前综合护理组与对照组患者心理状态评估指标差异无统计学意义(P>0.05),与对照组(76.92%)相比,护理后综合护理组焦虑指标、抑郁指标更低,综合护理组孕妇及家属的护理满意度(94.87%)较高(P<0.05)。结论通过综合护理模式可提升地中海贫血孕妇护理满意度,并改善其心理状态。     

Prenatal Diagnosis of Aortopulmonary Window by 2‐Dimensional Echocardiography: Summary of 8 Cases

Aortopulmonary window (APW) is a rare congenital heart anomaly. A total of 8 cases with APW confirmed by echocardiography and surgery were retrospectively reviewed and the echocardiographic features analyzed. Among the 8 APW cases, 5 were type II and 3 were type III, the latter of which includes 2 cases complicated with Berry syndrome. Prenatal echocardiography can provide accurate information for the diagnosis of fetal APW. The prognosis depends on the timing of surgery and the nature of the associated cardiac anomalies.     

Prenatal diagnosis of caudal regression with heterotaxy syndrome: “A mermaid with a broken heart”

Caudal regression syndrome (CRS) is a rare congenital malformation with varying degrees of early gestational developmental failure. It is characterized by agenesis of the sacrum and lumbar spine, with lower limb neurological deficit and accompanying deformities of the pelvis, lower extremities, genitourinary, and gastrointestinal systems. We report a case of CRS associated with rare complex congenital heart defect, that is, heterotaxy syndrome, diagnosed prenatally.

Literature Review of the Association Between Prenatal Education and Rates of Cesarean Birth Among Women at Low Risk

A review of the literature was performed to explore the association between prenatal education and rates of primary cesarean birth for women at low risk for cesarean birth. Most women who are nulliparous with a singleton fetus of term gestational age and in the vertex position are considered to be at low risk and favorable for a vaginal birth, yet the cesarean birth rate for women at low risk was 25.6% in 2019. It has been suggested that the rise in the cesarean birth rate among low-risk women may not be due to medical indications but, rather, to nonmedical factors, such as a provider’s or woman’s preference or lack of prenatal education. Evidence from this literature review supports the premise that prenatal education classes should be routinely incorporated into maternity care in an effort to reduce cesarean birth rates for the low-risk population.     

孕前超重及肥胖女性孕中期子宫-胎盘血流动力学的变化

目的探讨孕前超重及肥胖女性孕中期子宫-胎盘血流动力学及胎儿生长发育指标的变化。 方法回顾性选取2019年6月至2020年9月在唐都医院进行产前检查并行胎儿超声心动图检查的孕妇127例。依据孕前体质量指数（BMI）将孕妇分为正常对照组55例、超重组45例和肥胖组27例。对3组孕妇的一般资料、子宫-胎盘血流、胎儿生物学测量指标和大脑中动脉、脐动脉血流进行比较分析。 结果与正常组孕妇相比，超重组及肥胖组孕妇双侧子宫动脉收缩期峰值血流速度（Vs）、舒张期峰值血流速度（Vd）及搏动指数（PI）均升高，3组比较差异均有统计学意义（P均＜0.05），其中肥胖组孕妇双侧子宫动脉PI较超重组升高（P均＜0.05）。与正常组比较，肥胖组和超重组胎儿脐动脉游离段血流速度不同程度减低，3组比较差异均有统计学意义（Vs：F值=4.41，P=0.01；Vd：F值=4.03，P=0.02）；进一步两两比较，超重组与正常组Vd比较，差异有统计学意义（P＜0.05）；肥胖组与正常组Vs比较，差异有统计学意义（P＜0.05）。 结论孕前超重及肥胖女性孕中期子宫-胎盘循环血流动力学已经出现明显改变，应用超声实时监测这些参数变化对指导临床合理控制孕期体重，避免或减少相关并发症有潜在价值。     

Early prenatal vitamin D concentrations and social-emotional development in infants

Background: Many pregnant women in the United States have suboptimal vitamin D, but the impact on infant development is unclear. Moreover, no pregnancy-specific vitamin D recommendations have been widely accepted.

Aims: Given the ubiquitous expression of vitamin D receptors in the brain, we investigated the association between early prenatal plasma 25-hydroxyvitamin D (25(OH)D) concentrations and children’s social and emotional development in the Newborn Epigenetic Study, a prospective study of pregnancies from 2009 to 2011 in Durham, North Carolina.

Methods: We measured 25(OH)D concentrations in first or second trimester plasma samples and categorized 25(OH)D concentrations into quartiles. Covariates were derived from maternal questionnaires. Mothers completed the Infant Toddler Social-Emotional Development Assessment when children were 12–24 months of age. We used multivariable linear regression to evaluate associations between 25(OH)D and specific behavior scores, adjusted for season of blood draw, maternal age, education, parity, smoking, marital status, prepregnancy BMI, and infant gender. We investigated effect-measure modification by race/ethnicity.

Results: Of the 218 mother–infant pairs with complete data, Black mothers had much lower 25(OH)D concentrations as compared to White and Hispanic mothers. After adjustment, lower prenatal 25(OH)D was associated with slightly higher (less favorable) Internalizing scores among White children, but lower (more favorable) Internalizing scores among Black and Hispanic children. Lower prenatal 25(OH)D also appears to be associated with higher (less favorable) dysregulation scores, though only among White and Hispanic children.

Conclusions: Though imprecise, preliminary results warrant further investigation regarding a role for prenatal vitamin D on children’s early social and emotional development.
