With the increase in maternal mortality and morbidity United States, it is imperative to understand what aspect Maternal-Fetal Medicine provider density has on this. Our study’s objective was determine relationship between state-specific ratios of specialists. State from 2010 2018 were calculated Centers for Disease Control National Center Health Statistics database (Maternal defined as deaths ...

In this speculative paper, I consider the relationship between oxidative stress and the evolution of placentation in eutherian mammals. I argue that epitheliochorial placentation, in which fetal tissues remain separated from maternal blood throughout gestation, has evolved as a protective mechanism against oxidative stress arising from pregnancy, particularly in species with unusually long gest...

Background: Despite the progress of family planning programs, a significant proportion of pregnancies are still unplanned which threatens the different dimensions of community health. Unplanned pregnancy affects parent's-child association. Maternal-fetal attachment provides a model for the child's mental-social function at present and in the future. Objectives: This study was conducted to dete...

background & aim: abortion is the third leading cause of maternal mortality. the attitude of women towards abortion is one of the most important factors involved in this issue. this study aimed to evaluate the attitude of women of reproductive age towards induced abortion. methods this cross-sectional study was performed on 450 women of reproductive age in fatemieh hospital in hamedan, iran in ...

BACKGROUND Manganese (Mn) is an essential element and a potential toxicant for developing organism. Deficiency and excess of it were both deleterious to fetal growth in experimental animals. However, literature on relationship between Mn status and birth outcome in humans is sparse. METHODS Mn concentrations were measured in mother whole blood (MWB) and umbilical cord blood (UCB) in 125 pairs...

Background Several factors may cause infertility and fetal loss. Blood groups antigens seem to be implied in the mechanisms of infertility and fetal loss. Maternal natural antibody can react against father’s blood group antigens on spermatozoa. The effects of parental blood group system on infertility and fetal surveillance perceived by its manifestation in prezygotic (caused infertility) and ...

BACKGROUND Our objective was to determine what effect maternal BMI has on fetal growth rate in the early first trimester. METHODS This was a prospective observational study of singleton pregnancies with certain dates, initially presenting for a transvaginal scan (TVS) before 12 weeks of gestation. Maternal characteristics (BMI, ethnicity, maternal age, obstetric history, abdominal pain and va...

Among all mammals, fetal growth and organ maturation must be precisely synchronized with gestational length to optimize survival at birth. Lack of pulmonary maturation is the major cause of infant mortality in preterm birth. Whether fetal or maternal genotypes influence the close relationship between the length of gestation and lung function at birth is unknown. Structural and biochemical indic...

Fetal macrosomia is associated with a number of health complications for both mother and infant in the immediate, short, and long-term. Maternal obesity and excessive gestational weight gain (GWG) have long been associated with fetal macrosomia, however the impact of maternal lifestyle factors such as dietary intake and energy balance, in combination with the timing and composition of weight ga...

Excess L-tryptophan (L-Trp) in the diet decreases fetal body weight. However, the relationship between L-Trp concentration and its effects on maternal, placental, and fetal growth are not well-understood. We investigated the effects of excess L-Trp intake on maternal, placental, and fetal growth. Female mice were fed a 20% casein diet (control diet) or control diet plus 2% or 5% L-Trp during ge...
