Since the end of the twentieth century the number of birth by caesarean section (CS) has increased. In Poland in 2014, 42,8 % of deliveries was CS. On the one hand the number of maternal and newborn deaths decreases, but on the other hand caesarean section should be performed only if it is medically necessary. Alarming are reports that cesarean delivery may increase the risk of : autoimmune diseases, childhood allergies and asthma. The scientists from Italy carried out a study which showed that the intestinal flora of caesarean and vaginally delivered infants appears to be very different.
Aortic coarctation (CoA) constitutes 6-8% of all live births with hearth diseases. It can occur in various stages: from a discrete constriction of the aortic isthmus to the hypoplasia of the aortic arch. Prenatal diagnosis of CoA may result in lower mortality rate and better haemodynamic parameters (due to the early operation of CoA) by sustaining the patency of the aorta (1). The way to treat the fetus with CoA could be sustained, intermittent maternal hyperoxygenation (HO). Scientists discovered that HO can indicate the increase of left cardiac dimensions and the aortic isthmus (in fetuses with isolated CoA). Effects are mostly noticed in 4th week of treatment. The duration of the HO should dependent on left heart dimensions
The research conducted by scientists from the Swedish Research Council for Health, Working Life and Welfare, and the Karolinska Institutet, shows that changes in body weight between successive pregnancies may affect the risk of intrauterine fetal death and increased infant mortality.

American scientists report that women with endometriosis, who are 40 years old and less, are under greater risk of coronary heart disease. The results of the study were published in Circulation Cardiovascular Quality and Outcomes. Read full text »
Potential health benefits offered by the introduction of dark chocolate to your daily diet are still growing. The ingredients in cocoa not only improve our mood but also prevent obesity and reduce blood sugar levels which leads to preventing type 2 diabetes. It was also proved that eating chocolate lowers blood pressure. This time, researchers examined the effects of daily consumption of chocolate during pregnancy on fetal growth and development. The results were presented at the congress of The Society for Maternal-Fetal Medicine in Atlanta in 2016. Read full text »
Endometriosis is a chronic gynecological disease affecting a lot of women. It is defined as a presence of endometrium outside the proper place of occurrence, which is the uterine cavity. It may occur at any age however, it mainly concerns young women in their reproductive period, involving 10 percent of them. Read full text »
Scientists from Stanford University School of Medicine have made an attempt to describe the differences in both composition and amount of bacteria in the birth canal of women who gave birth prematurely and at a due date. Their research has led to discoveries that might soon contribute to designing new screening that would allow for assessing the risk of premature labour in very early stages of pregnancy.
There is currently a rising interest in developing mucosal vaccines against a different bacterial pathogens. The main reason for using this route of antigen administration is that many infections are initiated at mucosal sites. Therefore, development of effective vaccines that neutralize infectious agents at mucosal surfaces is desired. According to the one of the latest issues of the Science journal, researchers successfully developed a mucosal vaccine against Chlamydia trachomatis – a common pathogenic microbe affecting genitourinary tract.
Researchers from Imperial College of London and University of Crete found that urine testing for the presence of specific metabolites in pregnant women can help in the diagnosis of preterm birth or fetal growth restriction. In the future, by identifying metabolic profiles in the urine of pregnant women it will be possible to reduce complications resulting from premature birth. The study was published in the journal BMC Medicine. Read full text »
Is it possible that microorganisms in vagina can protect against HIV infection and inhibit its replication? What is the population of these microorganisms? American scientists from University of Texas Medical Branch in Galveston developed a cell culture model of the vaginal epithelium, which allows identifying the bacteria that protect against HIV infection and other pathogens transmitted by sexual contact.
