Physically Active

Background: No specific physical activity guidelines are available for women in multiple pregnancy. Aim of the study was to assess the knowledge and experience of women regarding physical activity during their latest twin pregnancy. Methods: A cross-sectional study including women after a twin delivery was conducted in Poland. A questionnaire was distributed in 2018 via web pages and Facebook groups designed for pregnant women. Results: 652 women filled out the questionnaire completely. Only 25% of women performed any physical exercises during twin gestation. The frequency of preterm delivery was similar in physically active and non-active participants. 35% of the respondents claimed to have gained information on proper activity from obstetricians during antenatal counselling while 11% claimed to be unable to identify the reliable sources of information. 7% of women admitted to feel discriminated by social opinion on exercising during a twin pregnancy. Conclusions: The population of women with a twin gestation is not sufficiently physically active and is often discouraged from performing exercises during gestation. Therefore, it is crucial to inform obstetricians to recommend active lifestyle during a twin gestation and to provide reliable information on physical activity to pregnant women. Further research on this topic is necessary in order for obstetric providers to counsel women on appropriate exercise with a twin pregnancy.

Estimated Fetal Weight

AbstractFetal growth restriction is a strong risk factor for perinatal morbidity and mortality. Reliable standards are indispensable, both to assess fetal growth and to evaluate birthweight and early postnatal growth in infants born preterm. The aim of this study was to create updated Swedish reference ranges for estimated fetal weight (EFW) from gestational week 12–42. This prospective longitudinal multicentre study included 583 women without known conditions causing aberrant fetal growth. Each woman was assigned a randomly selected protocol of five ultrasound scans from gestational week 12 + 3 to 41 + 6. Hadlock’s 3rd formula was used to estimate fetal weight. A two-level hierarchical regression model was employed to calculate the expected median and variance, expressed in standard deviations and percentiles, for EFW. EFW was higher for males than females. The reference ranges were compared with the presently used Swedish, and international reference ranges. Our reference ranges had higher EFW than the presently used Swedish reference ranges from gestational week 33, and higher median, 2.5th and 97.5th percentiles from gestational week 24 compared with INTERGROWTH-21st. The new reference ranges can be used both for assessment of intrauterine fetal weight and growth, and early postnatal growth in children born preterm.

Perinatal Complications

The objective: conduct a comparative clinical and statistical analysis of obstetric and perinatal complications in singleton and multiple pregnancies after assisted reproductive technologies (ART) according to archival documents (pregnancy observation data and birth history) and identify features of multiple pregnancy. Materials and methods. During the period 2017–2019, 522 women gave birth in maternity hospital «Leleka» after assisted reproductive technologies, 331 women were observed in the maternity hospital «Leleka». 445 women gave birth with a singleton pregnancy and 77 with a multiple pregnancy. A clinical and statistical analysis of 150 pregnancy and childbirth histories was performed. All pregnant women were divided into two groups: Group I – 75 pregnant women with singleton pregnancies after ART; Group II – 75 pregnant women with multiple pregnancies after ART. The selection criteria for comparative clinical and statistical analysis were women whose pregnancies occurred as a result of ART, namely by in vitro fertilization (IVF) using five-day frozen embryos. Mathematical research methods were performed in accordance with the recommendations of O.P. Minzer (2013). The reliability of the cancellation of the mean pairs was calculated using the Student’s and Fisher’s criteria. Graphs were designed using the program «Microsoft Excel». Results. Complications of early pregnancy in multiple pregnancies were: anemia (47.8% vs. 22.9%; p<0.01), placental dysfunction (43.3% vs. 22.9%; p<0.01), the threat of abortion (41.8% vs. 28.6%; p<0.01). Complications of the second half of pregnancy: preeclampsia (52.7% vs. 20.6%; p<0.01), fetal growth retardation (20.0% vs. 7.4%; p<0.01), gestational anemia (76,4% vs. 32.4%; p<0.01), placental dysfunction (47.3% vs. 22.1%; p<0.05). Complications in childbirth in women with multiple pregnancies were as follows: premature rupture of membranes (30.9% vs. 10.3%; p<0.05), anomalies of labor activity (16.4% vs. 5.9%; p>0.05), fetal distress (29.1% vs. 14.7%; p<0.05), premature placental abruption (3.6% vs. the absence of this indicator in group I). In patients of group II with multiple pregnancies 3.7 times more often the pregnancy ended prematurely compared with singleton (21.8% vs. 5.9%; p<0.05). Early preterm births predominated, of which births occurred in 3.6% of cases at 22–28 weeks, 7.3% at 28–32 weeks, and 6.4% at 32–34 weeks. Significant increase in the frequency of 32.7% of abdominal births in multiple pregnancies against 11.8% of patients in pregnancy with a single fetus (p<0.01). The structure of indications in patients of group II was as follows: severe preeclampsia 27.8%, development of fetal growth retardation and fetal distress of 11.1%, respectively, premature placental abruption 16.7%, the following single indications (pelvic presentation of the fetus, transverse or oblique position of the fetus, clinically narrow pelvis, abnormalities of labor, scar on the uterus) – 33.3%. Significant increase in the total frequency of neonatal asphyxia of varying severity in multiple pregnancies (35.0% vs. 5.9%; p<0.05), fetal growth retardation (27.3% vs. 11.8%; p<0.01). Conclusions. Multiple pregnancies are a high risk factor for gestational anemia, preeclampsia, placental dysfunction, early fetal growth retardation, and fetal distress during pregnancy and childbirth. This causes a high level of abdominal delivery. Therefore, further research to predict and prevent obstetric and perinatal complications in multiple pregnancies after ART is relevant today. Keywords: obstetric and perinatal complications of pregnancy, multiple pregnancy, assisted reproductive technologies.
