Biochim Biophys Acta Mol Basis Dis 2021 Jun 9:166198. Epub 2021 Jun 9.

Fetal and Perinatal Medicine and Surgery Unit, Medical and Surgical Department of Fetus, Newborn and Infant - "Bambino Gesù" Children's Hospital IRCCS, Rome, Italy.

Some maternal infections, contracted before or during pregnancy, can be transmitted to the fetus, during gestation (congenital infection), during labor and childbirth (perinatal infection) and through breastfeeding (postnatal infection). The agents responsible for these infections can be viruses, bacteria, protozoa, fungi. Among the viruses most frequently responsible for congenital infections are Cytomegalovirus (CMV), Herpes simplex 1-2, Herpes virus 6, Varicella zoster. Read More

Hemoglobin Level and Associated Factors among Pregnant Women in Rural Southwest Ethiopia.

Biomed Res Int 2021 19;2021:9922370. Epub 2021 May 19.

Department of Nutrition and Dietetics, Jimma University, Jimma, Ethiopia.

Background: Anemia is a situation in which the number and size of red blood cells, or the concentration of hemoglobin, fall below established cut-off values. Low hemoglobin level during pregnancy favors the alteration of placental angiogenesis and resulted in restricting the availability of nutrients to the fetus and consequently causing fetal growth retardation and low weight at birth. This study is aimed at assessing the hemoglobin level and associated factors among pregnant women in rural communities of Jimma zone, Southwest Ethiopia. Read More

Continuous activation of polymorphonuclear myeloid-derived suppressor cells during pregnancy is critical for fetal development.

Cell Mol Immunol 2021 Jun 7. Epub 2021 Jun 7.

Department of Immunology, School of Basic Medical Sciences, Southern Medical University, Guangzhou, China.

The maternal immune system is vital in maintaining immunotolerance to the semiallogeneic fetus for a successful pregnancy. Although studies have shown that myeloid-derived suppressor cells (MDSCs) play an important role in maintaining feto-maternal tolerance, little is known about the role of MDSCs in pregnancies with intrauterine growth retardation (IUGR). Here, we reported that the activation of polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs) during pregnancy was closely associated with fetal growth. Read More

Intrauterine growth restriction followed by oxygen support uniquely interferes with genetic regulators of myelination.

eNeuro 2021 Jun 7. Epub 2021 Jun 7.

Children's Hospital of Chicago, Department of Pediatrics, Division of Neonatology, Chicago, Illinois, USA.

Intrauterine growth restriction (IUGR) and oxygen exposure in isolation and combination adversely affect the developing brain, putting infants at risk for neurodevelopmental disability including cerebral palsy. Rodent models of IUGR and postnatal hyperoxia have demonstrated oligodendroglial injury with subsequent white matter injury (WMI) and motor dysfunction. Here we investigate transcriptomic dysregulation in IUGR with and without hyperoxia exposure to account for the abnormal brain structure and function previously documented. Read More
