Introduction In vitro fertilization (IVF) singletons have a worse perinatal outcome than spontaneously conceived singletons, especially in terms of preterm birth and its complications. Material and methods An observational retrospective case control study was carried out. The study population consisted of 644 women in singleton pregnancies (336 IVF/intracytoplasmic sperm injection (ICSI); 308 controls) who delivered > 22 weeks of gestation at the 1 st Department of Obstetrics and Gynecology, Medical University of Warsaw, Poland, between 2004 and 2014. Controls were initially matched by age and parity and drawn from the group of deliveries following each IVF delivery. Collected data included maternal characteristics, incidence of pregnancy complications, time and mode of delivery, and neonatal outcome at delivery. Results The two study groups were initially matched for age and parity and were also similar with regard to BMI and gestational weight gain. The IVF treatment increased the odds of having vaginal bleeding in the first trimester (OR = 1.68; 95% CI: 1.0–2.86), placenta previa (OR = 5.15; 95% CI: 1.1–33.9), preterm delivery (OR = 2.06; 95% CI: 1.16–3.68), newborn’s low birth weight (OR = 2.27; 95% CI: 1.19–4.36) and elective cesarean section (OR = 2.39; 95% CI: 1.7–3.4). Conclusions The IVF singleton pregnancies have an increased risk of adverse perinatal outcome, among which prematurity remains the greatest problem. Therefore, they should be managed as high risk not only due to psychological reasons.

The incidence of VPTD, pre-eclampsia, and perinatal mortality during dichorionic twin pregnancy were associated with GWG ratio.

Due to the nature of their work, physicians are exposed to chronic stress. This may potentially lead to the widespread occurrence of occupational burnout syndrome (BS). The aim of this systematic review study was to summarize available published data concerning the prevalence of BS in Polish doctors. The literature search was performed using the following databases: PubMed/MEDLINE, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL) and Google Scholar. The last search was performed on September 27th, 2019. Only articles in English or Polish on graduated doctors practicing in Poland were taken into account. All types of original research were considered eligible. However, review articles, book chapters, case reports, case series, conference papers, study protocols and articles in languages other than English and Polish were excluded. There were no restrictions on age, seniority or specialty of study participants. The literature search revealed a total of 21 studies that met the inclusion criteria. The results of individual studies were very diverse, which makes it difficult to draw specific conclusions. However, the problem of burnout among Polish doctors is valid and worth special attention from society, health policy leaders, and doctors themselves. High-quality research is essential to for a better understanding of this topic.

The aim was to characterize sleep patterns in pregnant women in Poland and to analyze the relation between sociodemographic factors, pregnancy-related physical symptoms and sleep problems. A self-composed questionnaire, containing questions in Polish language, was distributed online via web pages and Facebook groups designed for pregnant women. The questionnaire included questions regarding sociodemographic data and information on the current pregnancy and sleep patterns over the past four weeks. Exactly 7207 respondents were included to the study. 77.09% reported sleep problems: nocturnal awakening (52.77%), sleep onset insomnia (20.23%), awakening too early (18.56%) and believed their sleep was too shallow (9.82%). Sleep onset insomnia (26.38%) and frequent awakening (62.88%) were most often reported in 3rd trimester, while daytime drowsiness (86.35%) and naps impeding daytime function (27.18%) in the 1st trimester of pregnancy. The analyzed demographic, socioeconomic and psychological issues had a small but significant influence on sleep problems occurrence (aOR 0.81–1.24). Time to conceive from 6 to 12 months of trying increased the risk of developing sleep problems during pregnancy (aOR 1.31). Pregnancy ailments increased the risk of sleep disturbances (aOR 1.53–2.59). Sleep disorders are prevalent among pregnant women in Poland. The evaluation of risk factors is essential in proper screening for sleep disorders in pregnant women.

The administration of vaginal progesterone after tocolysis in threatened preterm labor is associated with prolongation of pregnancy. The reduction of deliveries before 34 weeks was observed in patients presenting with contractions after 27 weeks gestation.
