ABSTRACT
Objective:To explore the application value of non-invasive prenatal testing (NIPT) technology in twin pregnancy.Methods:A total of 339 twin pregnant women who underwent NIPT at Dalian Municipal Women and Children′s Medical Center(Group), Dalian Jinpu New District Maternity and Child Health Hospital, and Dalian Lvshunkou District People′s Hospital from July 1, 2019 to June 30, 2021 were continuously retrospectively included. The clinical characteristics and test results of pregnant women with high-risk and low-risk were analyzed.Results:Among 339 pregnant women, 336 were successfully tested, with a success rate of 99.12%(336/339); 6 pregnant women were at high risk of NIPT, with a positive screening rate of 1.77%(6/339), including 1 case of high risk of trisomy 13, 2 cases of high risk of trisomy 18, and 3 cases of high risk of Trisomy 21; the results of amniocentesis for 2 high-risk pregnant women were not abnormal.Conclusions:NIPT technology is non-invasive, safe and efficient, and is suitable for large-scale prenatal screening. However, the detection accuracy of pregnant women with twin pregnancy needs to be improved.
ABSTRACT
Objective:To explore whether assisted reproductive technology (ART) can affect the mental health of pregnant women during pregnancy.Methods:Convenient sampling method was used to select 500 pregnant women who underwent prenatal examination in Dalian Women and Children′s Medical Group from July 2019 to July 2020, including 193 cases of ART pregnant women (observation group) and 307 cases of natural pregnant women (control group). PEM-D psychosomatic holistic diagnosis and treatment system combined with Symptom Checklist- 90 (SCL-90), 7- item Generalized Anxiety Disorder Scale (GAD-7), 9-item Patient Health Questionnaire (PHQ-9) and Pittsburgh Sleep Quality Index (PSQI) were used to evaluate and compare the mental health status between the two groups.Results:The total score of SCL-90 in the observation group was (154.34 ± 14.42), which was significantly higher than that in the control group (142.42 ± 14.39), the difference was statistically significant ( t=5.35, P<0.05). The scores of anxiety, depression and paranoia in the observation group were (2.17 ± 0.47), (2.15 ± 0.68), (1.78 ± 0.45), which were significantly higher than those in the control group (1.95 ± 0.52), (1.77 ± 0.55), (1.58 ± 0.39), the differences were statistically significant ( t=2.86, 3.88, 3.20, all P<0.015). The scores of GAD-7 and PHQ-9 in the observation group were (6.72 ± 2.44), (5.43 ± 2.54), which were significantly higher than those in the control group (5.76 ± 2.47), (3.74 ± 1.66), the differences were statistically significant ( t=2.52, 3.57, both P<0.05). There was no significant difference in PSQI scores between the two groups ( P>0.05). Conclusions:ART affects the mental health of pregnant women, especially increases the level of depression and anxiety. We should provide corresponding psychological support and help for these pregnant women to reduce their depression and anxiety level.
ABSTRACT
With the change of medical model, the impact of common psychological disorders on the occurrence, development and treatment has been paid more attention to. If the diagnosis is not timely, it can result in serious long-term effects on the wellbeing of women, their partners and infants. We reviewed the recent foreign studies on the common psychological problems of perinatal women and summarize the epidemiology, identification and interventions, so as to understand the impact on the offspring. It is of great significance to strengthen the training for health professionals in wider psychosocial assessment and to adopt effective intervention methods to alleviate the adverse psychological state of perinatal women.
ABSTRACT
Objective To explore the normal reference range of fetal gallbladder in 28 to 35 weeks of pregnancy under magnetic resonance imaging characteristics, observe and explore the growth and development of fetal gallbladder, and provide a new detection method for evaluating fetal growth and development for prenatal examination. Methods One hundred single pregnant women who had underwent fetal abdominal magnetic resonance imaging from June 2017 to May 2018 in Dalian Municipal Women and Children′s Medical Center were selected. The pregnant women were divided into 2 groups according to the gestational weeks: group A (pregnancy 28 to 31 weeks, 64 cases) and group B (pregnancy 32 to 35 weeks, 36 cases). The length, width and transverse diameter of fetal gallbladder were measured by magnetic resonance, and the gallbladder volume was calculated. Results In group A, magnetic resonance result showed that 1 case had no gallbladder and 1 case had double gallbladder, but the fetal gallbladders of these 2 cases were normal after birth. The display rate of fetal gallbladder in group A was 98.4% (63/64), and that in group B was 100.0% (36/36); the abnormal rate in group A was 3.1% (2/64), and that in group B was 0. The length, width, transverse diameter and volume of gallbladder in group B were significantly higher than those in group A: (16.5 ± 6.0) mm vs. (13.2 ± 4.2) mm, (6.5 ± 3.5) mm vs. (5.2 ± 1.1) mm, (6.8 ± 2.6) mm vs. (6.4 ± 3.4) mm and (373.3 ± 284.1) mm3 vs. (258.5 ± 232.4) mm3, and there were statistical differences (P＜0.05). Conclusions Fetal magnetic resonance during lategestation has the new means of prenatal evaluation of fetal growth and development, which has clinical application value.
ABSTRACT
Objective To investigate the MRI findings and diagnostic value of congenital abdominal wall defect.Methods Eighteen fetuses with congenital abdominal wall defect were analyzed retrospectively, and the MRI features were analyzed. Results In 18 cases of congenital defect of abdominal wall, fetal MRI showed 6 cases had gastroschisis and 12 cases had omphalocele. They were diagnosed accurately by MRI. Conclusions Congenital abdominal wall defect has characteristic MRI findings.MRI is of great significance in prenatal diagnosis.
ABSTRACT
Objective To explore the relationship between the level of the pregnant women serum inhibin A and premature rupture of membranes.Methods Thirty-two pregnant women with the gestational age 36-37+6weeks were selected,including 18 cases with premature rupture of membranes (premature rupture of membranes group) and 14 cases without premature rupture of membranes (none premature rupture of membranes group).The serum level of inhibin A was measured by enzyme-linked immunosorbent assay method.Results The serum level of inhibin A in premature rupture of membranes group was significantly higher than that in none premature rupture of membranes group(1 253.5 ng/L vs.698.1 ng/L), and there was statistical difference (P<0.05).The receiver-operating characteristic curve analysis result showed that the optimal cut-off value of serum level of inhibin A to predict premature rupture of membranes was 984.45 ng/L,with a sensitivity of 72.2% and a specificity of 78.6%,and the area under the curve was 0.77(95% CI 0.59-0.95).Conclusions The serum level of inhibin A has a certain predictive value for premature rupture of membranes.
ABSTRACT
Objective To research the clinical characteristics of neonates with non-immune hydrops fetalis.Methods The clinical data of eleven non-immune hydrops fetalis who admitted from January 2015 to November 2016 were retrospectively studied.Imaging manifestations,cause analysis and outcomes were explored and analyzed with descriptive statistical methods.Results The most common abnormal images in this study were hydrothorax,seroperitoneum and subcutaneous edema.Of all the cases,cardiac anomalies were in 2 cases,chylothorax in 3 cases,chromosome abnormality in 1 case,meconium peritonitis in 1 case,bladder rupture in 1 case and unknown reasons in 3 cases.Of all the cases,3 cases were terminated pregnancy before 28 weeks,2 cases were fetal intrauterine death,and 6 cases were live births,among whom 2 cases died within 48 h of newborn and 3 cases survived.Placental pathologic conditions of 8 cases were edematous placentas.Conclusions The mortality of non-immune hydrops fetalis is high.Its etiology,pathogenesis and the timing of pregnancy termination need to be explored.
