Article Abstract
The authors analyze the results of prenatal diagnosis carried out in women during the first and second pregnancy trimesters. Cytogenetic screening was carried out in risk-group pregnant women, i.e. in women aged over 36, in cases with family history of chromosome mutation or a previous child with chromosome aberration, or a sex-linked disease in one of family members, etc. Chromosome preparations from amniotic fluid cell cultures and 'direct' chromosome preparations from chorionic villi were analyzed. The authors discuss the efficacy of prenatal diagnosis in various pregnancy periods, fetal tissue collection methods and quantities necessary for the examination.

Background: Gestational Zika virus (ZIKV) infection is associated with the development of congenital Zika syndrome (CZS), which includes microcephaly and fetal demise. The magnitude and quality of orthoflavivirus-specific humoral immunity have been previously linked to the development of CZS. However, the role of ZIKV NS1-specific humoral immunity in mothers and children with prenatal ZIKV exposure and CZS remains undefined.

Background And Purpose: Anxiety during pregnancy is common, and exposure to heightened anxiety during pregnancy may influence children's brain development and functioning. However, it is unclear if exposure to low levels of anxiety in utero would also impact the developing brain. The current prospective and longitudinal study included 40 healthy pregnant women without pregnancy complications or previous diagnosis of anxiety disorders.
