Fetal Reduction

ABSTRACTBackgroundThere is currently insufficient evidence regarding the prognosis of multi-fetal pregnancies reduced to twins or singletons. We compared the perinatal outcomes of deliveries following fetal reduction with the perinatal outcomes of deliveries without fetal reduction. MethodsWe carried out a retrospective cohort study of all births in British Columbia between 2009 and 2013, using information from a population-based database. Comparisons were made between all women who had a fetal reduction to a twin or a singleton pregnancy with those who did not undergo a fetal reduction procedure. The outcomes of interest were preterm delivery and composite severe neonatal morbidity or perinatal mortality. Generalized estimating equations adjusting for maternal age, parity, pre-pregnancy weight, use of in vitro fertilization and baby’s sex were used to estimate odds ratios (OR) and 95% confidence intervals (CI). ResultsAmong 207,273 deliveries, 139 (0.07%) had a fetal reduction. Of these, 89 women delivered twins and 50 delivered singletons. Women who had a fetal reduction were more likely to have conceived with in vitro fertilization (77.6%) compared with those who did not (3.31%). Twins delivered after fetal reduction had lower rates of neonatal morbidity/mortality (OR 0.19, 95% CI 0.08-0.42) compared with unreduced triplets but rates similar to those of twins without a reduction procedure (OR 1.44, 95% CI 0.81-2.58). Singletons delivered after fetal reduction had non-significantly lower rates of neonatal morbidity/mortality than unreduced twins (OR 0.75, 95% CI 0.36-1.57) but significantly higher rates of neonatal morbidity/mortality (OR 3.98, 95% CI 1.91-8.30), preterm delivery and being small for gestational age than singleton pregnancies without a reduction procedure. ConclusionPerinatal outcomes of twins delivered after fetal reduction are better than those of unreduced triplets and similar to those of unreduced twins.

Vitro Fertilization

Pregnancies that occur after assisted reproduction procedures constitute high-risk pregnancies. There is a lack of sufficient epidemio-logically based data on this issue in Latvia. The aim of this study was to compare the maternal and perinatal outcomes of multiple pregnancies conceived by in vitro fertilization (IVF) in comparison with spontaneous multiple pregnancies. This retrospective cohort study (2007–2014) analysed data from population-based Medical Birth Register (MBR). There is a statistically significant increase of multiple births from IVF pregnancies – an average 2% per year (p< 0.01). Newborns of IVF multiple births have higher odds of low birth weight (OR = 1.2) and congenital anomalies (OR = 1.6). Maternity characteristics showed that mothers in the IVF group were significantly older than those in the control group (≥35 years) (OR = 2.1) and primipara births (OR = 4.1). Multiple births conceived by IVF have similar outcomes as spontaneously conceived multiples in the perinatal period, although the rates of congenital anomalies after IVF are just slightly higher than in control group.

Pregnancy And Delivery

The objective: to study the structure and frequency of complications of pregnancy, deliveries and perinatal outcomes in three groups of women: women with infertility and obesity, treated by application of in vitro fertilization (hereinafter IVF), pregnant women after IVF application with normal body weight, and pregnant women on the background of obesity which did not have an infertility in past history. Materials and methods. A retrospective analysis of 221 case histories of pregnancies and labors in women who were treated and gave birth in the Pregnancy and delivery pathology Department of SI «Institute of Pediatrics, Obstetrics and Gynecology named after Acad. O. M. Lukyanova of NAMS of Ukraine» for 2012 – 2016 years was carried out. Results. The overwhelming majority of pregnant women after IVF on the background of obesity are primaparas, who have a complicated obstetric history, hormonal changes in the form of progesterone deficiency predominantly and chronic inflammatory processes. Pregnancy with a combination of infertility, treated by the means of IVF application, and obesity, in most cases is accompanied by a long-term threat of termination of pregnancy (48.8%), threatening preterm deliveries (56%), placental dysfunction (41.5%), premature rupture of the amniotic membranes (41.5%), other problems during pregnancy, at the same time, every second woman (58.5%) had a combination of several complications, and required a long-term and repeated inpatient treatment (53.7%). The specific gravity of surgical delivery was 90%, and 16.2% of such deliveries were complicated by pathological blood loss. The number of preterm deliveries was 17.1%, with perinatal losses up to 11.3‰. Among full-term newborns 21.3% of newborns had malnutrition of the I degree and 17% of them had hypoxic-ischemic lesion of CNS. Conclusion. The course of pregnancy, delivery and the postpartum period in the studied contingent of women has a significant frequency of complications, mainly the coinciding ones, which affects on the consequences of perinatal outcomes and requires further study of this problem and the development of differentiated algorithms for antenatal observation. Key words: pregnancy, obesity, in vitro fertilization, complications, delivery, newborn.

Fertility Treatments

Abstract Background: In vitro fertilization (IVF) births contribute to a considerable proportion of preterm birth (PTB) each year. However, there is no formal surveillance of adverse perinatal outcomes for less invasive fertility treatments. The study objective was to determine the effect of fertility treatment (in vitro fertilization, intrauterine insemination, usually with ovulation drugs (IUI), or ovulation drugs alone) on preterm birth, compared to no treatment in subfertile women.Methods: The Fertility Experiences Study (FES) is a retrospective cohort study conducted at the University of Utah between April 2010 and September 2012. Women with a history of primary subfertility self-reported treatment data via survey and interviews. Participant data were linked to birth certificates and fetal death records to asses for perinatal outcomes, particularly preterm birth.Results: A total 487 birth certificates and 3 fetal death records were linked as first births for study participants who completed questionnaires. Among linked births, 19% had a PTB. After adjustment for maternal age, paternal age, maternal education, annual income, religious affiliation, female or male fertility diagnosis, and duration of subfertility, the odds ratios and 95% confidence intervals (CI) for PTB were 2.17 (CI: 0.99, 4.75) for births conceived using ovulation drugs, 3.17 (CI: 1.4, 7.19) for neonates conceived using IUI and 4.24 (CI: 2.05, 8.77) for neonates conceived by IVF, compared to women with subfertility who used no treatment during the month of conception. A reported diagnosis of female factor infertility increased the adjusted odds of having a PTB 2.99 (CI: 1.5, 5.97). Duration of pregnancy attempt was not independently associated with PTB. In restricting analyses to singleton gestation, odds ratios remained elevated but were not significant for any type of treatment.Conclusion: IVF, IUI, and ovulation drugs were all associated with a higher incidence of preterm birth and low birth weight, predominantly related to multiple gestation births.
