Abstract:

Background and Objectives: Pregnant women face an increased risk of experiencing negative consequences due to COVID-19 infection. Our study aimed to identify outcomes for both mothers and fetuses associated with COVID-19 during each trimester, as well as to identify post-COVID symptoms in this population. Materials and Methods: Among the total population, 14 females were infected during the first trimester, 25 during the second, and 66 during the third trimester. Weekly follow-ups were conducted until delivery. Seventy-five females (71.4%; 95% CI:26.9–115.9%) were admitted to the hospital seco

Abstract:

Second-trimester maternal serum screening for Down syndrome is now well established, and permits detection of up to 70% of cases. The disadvantage of this sort of screening is that the timing of maternal blood sampling is relatively late (after 15 weeks). There is an accumulating body of evidence to suggest that in the first trimester concentrations of a number of pregnancy-associated proteins and hormones differ in chromosomally normal and abnormal pregnancies. A first-trimester maternal serum screening test for Down syndrome may therefore be possible. In addition, new methods of screening ha

Abstract:

Maternal 25 dihydroxycholecalciferol is the storage form the vitamin D. It gets activated to 1,25, Dihydroxycholecalciferol (vitamin D3) in the kidneys. Pregnancy increases requirement for the vitamin D3. The 1,25 dihydroxycholecalciferol is produced by the fetal kidneys from maternal sources of 25 dihydroxycholecalciferol. Vitamin D3 is essential for intestinal calcium absorption and bone mineralization in fetus.104 venous blood samples were used to study 25 hydroxycholecalciferol and serum calcium levels. Experimental group involved venous blood samples from 100 ANC between 20-40 years. In t

<strong>Background:</strong> Maternal haemoglobin levels affect pregnancy outcomes and the mother’s and neonate’s health. This cohort study examined the relationship between the mother’s blood haemoglobin levels over the three trimesters and the neonates at birth. <strong>Methods:</strong> About 200 pregnant Territory Care Centre patients participated in the study. Researchers measured the mother’s haemoglobin in the third trimester. After giving birth, they checked foetal and neonatal cord blood levels. To summarise haemoglobin levels, descriptive statis

Background and Objectives: During pregnancy, iron deficiency anaemia is a common problem associated with health risks for both the mother and her foetus/infant. This study aimed to investigate the prevalence of iron deficiency, iron deficiency anaemia, and related dietary patterns in pregnant women in Latvia. Materials and Methods: This cross-sectional, multicentre study included pregnancy data from 974 women. The sample selection was based on the stratification principle (population of women of childbearing age in regions of Latvia). Maternal demographic details, anthropometric measurements,

Abstract:

Abstract Background: In the United States, Down syndrome screening is still performed mainly in the second trimester, using 3 or 4 markers. Moving screening into the first trimester has the advantage of earlier diagnosis. Currently, first-trimester screening typically includes maternal serum pregnancy-associated plasma protein-A (PAPP-A), the free β-subunit of human chorionic gonadotropin (free β), and ultrasound measurement of nuchal translucency thickness (NT). The current report describes a case–control study of serum invasive trophoblast antigen (ITA) and its possible inclusion in first-tr

AbstractObjectiveMaternal weight in pregnancy contributes to a glycemic environment that affects fetal growth. Gut peptides (glucagon-like peptide 1 (GLP1), glucose-dependent insulinotropic peptide (GIP), ghrelin, and peptide YY (PYY)) have been related to insulin sensitivity and secretion, weight control, and adipose tissue metabolism. This study aimed at examining the associations of gut hormones during pregnancy with maternal glucose homeostasis, maternal weight, and fetal growth.MethodsA total of 55 pregnant nonobese, nondiabetic Caucasian women were examined during the three trimesters of

Abstract Background In sub-Saharan Africa, malaria in the first half of pregnancy is harmful for both the mother and her fetus. However, malaria in the first trimester of pregnancy, when women are usually not protected against malaria, has been little investigated. For the first time, we assessed the effects of malaria in the first trimester on maternal and birth outcomes using a preconceptional study design. Methods From June 2014 to March 2017, 1214 women of reproductive age were recruited and followed monthly until 411 became pregnant. The pregnant women were then followed from 5–6 weeks of

Abstract:

An improvement in prenatal screening for chromosomal defects has been achieved by combining sonography and biochemical markers. Analyzing markers taken from maternal blood such as pregnancy-associated plasma protein A and free β-human chorionic gonadotropin in combination with the ultrasound marker nuchal translucency provides detection rates of 90% for the most important chromosomal anomalies. In addition, nuchal translucency is a marker for severe heart defects. This report discusses the potential of new markers such as the nasal bone.

Abstract:

Primary hyperparathyroidism (PHPT) during pregnancy is associated with significant maternal and fetal risks. Prompt diagnosis and effective management during pregnancy can improve both maternal and fetal outcomes. However, there is no consensus with regard to conservative versus surgical management especially in the first and third trimester. We report three cases of PHPT associated with pregnancy that underwent parathyroidectomy each in a different trimester. Cases 1 and 2 were found to have hypercalcaemia and elevated parathyroid hormone levels in the second and first trimesters, respectivel

In Los Angeles (LA) County, 89% of cities are at least partially fluoridated. Drinking water is the primary source of fluoride exposure in the US. Studies conducted in Mexico and Canada suggest that prenatal fluoride exposure, at levels relevant to the US, may contribute to poorer neurodevelopment in offspring. However, data on biomarkers and patterns of fluoride exposure among US pregnant women are scarce. This study examined urinary fluoride levels a
