Second-trimester maternal serum screening (MSS) for Down syndrome has been widely used in routine prenatal care in developed countries. The screening combines maternal age-specific risk of Down syndrome with risk estimation obtained by measuring maternal serum markers to assign women an expected risk of having a term Down syndrome pregnancy. Diagnostic tests were offered to women whose risk exc...

BACKGROUND Helicobacter pylori (H. pylori) was linked with several extragastrointestinal diseases, including preeclampsia and intrauterine growth restriction of fetus. One of the signals which can be transferred from mother to fetus is the H. pylori IgG antibody. Aims. We utilized a commercial immunochromatographic kit to detect the antibody in maternal and cord serum. METHODS Three hundred a...

The purpose of the current study was to propose a Korean-specific parameter set for calculating the risk of Down syndrome in the second trimester of pregnancy and to determine the screening performances of triple and quadruple tests in Korean women. Using the data on triple or quadruple screening from three hospitals in Korea during 7 yr, we re-converted the concentrations of four serum markers...

Effective screening for major aneuploidies can be provided in the first trimester of pregnancy. Screening by a combination of fetal nuchal translucency and maternal serum free-β-human chorionic gonadotrophin and pregnancy-associated plasma protein-A can identify about 90% of fetuses with trisomy 21 and other major aneuploidies for a false-positive rate of 5%. Improvement in the performance of f...

Preterm birth is one of the most important global issues. Mortality and morbidity among children under 5 years, including neonates, affected by preterm birth. A good maternal care, health workers, facilities play an role in outcome pregnancy, An early screening test for pregnancy crucial to find any abnormality thus can be predicted following treatment may applied without delay. One potential ...

OBJECTIVE To evaluate the influence of maternal insulin dependent diabetes mellitus (IDDM) on maternal serum free beta-hCG, PAPP-A and fetal nuchal translucency (NT), thickness at 11 to 13(+6) weeks of gestation in a large cohort of women screened prospectively for chromosomal anomalies. METHODS Information on maternal IDDM status, maternal serum biochemical marker levels and fetal NT were co...

BACKGROUND Serum human chorionic gonadotropin (hCG) and hCG free beta-subunit tests are used in combination with unconjugated estriol and alpha-fetoprotein in the triple screen test, and with the addition of inhibin-A in the quadruple marker test for detecting Down syndrome in the second trimester of pregnancy. These tests have a limited detection rate for Down syndrome: approximately 40% for h...

Down syndrome (DS) is a birth defect with huge medical and social costs, caused by trisomy of whole or part of chromosome 21. It is the most prevalent genetic disease worldwide and the common genetic cause of intellectual disabilities appearing in about 1 in 400-1500 newborns. Although the syndrome had been described thousands of years before, it was named after John Langdon Down who described ...

OBJECTIVES To estimate improvements to four antenatal screening tests for Down's syndrome (first trimester Combined, second trimester Quadruple, and first and second trimester Integrated and Serum Integrated tests) based on adding ductus venosus pulsatility index (DVPI), fetal nasal bone examination (NBE) and serum placental growth factor (PlGF). SETTING Statistical analysis of data from seve...
