The present work evaluated the efficacy of a prenatal diagnosis program in which amniocentesis and chorionic villus sampling were offered free of charge to all pregnant women in Israel aged > or = 37 years. The number of Down syndrome (DS) live births that occurred during the period of the program (1978-92) was correlated to the prevalence of old maternal age (> 35 years) and the utilization of prenatal test in the Jewish and non-Jewish populations in 1990 and 1992. It was noted that in the Jewish population, there was a slight increase in the DS live birth rate, from 1.05 in 1978, to 1.37 DS cases/1,000 live births in 1987, which corresponded to an increase in the prevalence of older pregnant women, from 8.0% in 1978 to 14.8% in 1987. Thereafter, however, there was a continuous decline, to 0.71 DS cases/1,000 live births in 1992, as a result of increased acceptance of prenatal testing by women > or = 37 years (67%) and, recently, also by younger women (from 5.6% in 1990 to 14% in 1992). In the non-Jewish population, there has been a very low acceptance rate of prenatal testing (23.3-16.1% in women > or = 37 years and 0.36-0.63% in women < 37 years). As a result, a very low prenatal detection rate (8-16% of all DS cases) and a high prevalence of DS live births (1.4 cases/1,000 live births) were observed. We suggest that a unique genetic counseling approach is required in the non-Jewish population to improve prenatal DS prevention in Israel.

The objective of this study is to explore the impact of the use of granulocyte-macrophage colony-stimulating factor (GM-CSF) in female undergoing assisted reproductive technology (ART) on reproductive outcomes. A literature search was performed using electronic databases (PubMed, EMBASE, Web of Science, CNKI, Wanfang data, Geen Medical, and Cochrane Library). Risk ratio (RR), odds ratio (OR), and mean difference (MD) with 95% confidence intervals (CI) for various outcomes were presented.

Objectives: Sickle cell disease (SCD), which disproportionately affects minorities, increases complications during pregnancy. Severe maternal mortality is increased in women with SCD, including morbidity related to the disease and other nondisease-related complications. It also can have devastating complications for fetuses, with increases in premature birth and low birth weight.

Objective: We investigated whether the addition of a luteal phase support drug benefits pregnancy and perinatal outcomes in modified natural-cycle frozen-thawed embryo transfer (mNC-FET) for women up to the age of 35 years.
Methods: We analyzed the clinical data of 3658 mNC-FET cycles of women up to the age of 35 years from the Reproductive Center of the Third Affiliated Hospital of Zhengzhou University from January 2018 to December 2020 in a retrospective cohort study. The cycles were divided into three groups based on the luteal phase support protocol used.

Objective: To analyze the temporal and territorial relationship between health system financing fragmentation and maternal mortality in the last two decades in Mexico.
Methods: We conducted an ecological-longitudinal study of the maternal mortality ratio (MMR) in the 32 states of Mexico during the period 2000-2022. Annual MMRs were estimated at the national and state levels according to health insurance.

Infertility has emerged as a significant global health concern. Assisted reproductive technology (ART) assists numerous infertile couples in conceiving, yet some experience repeated, unsuccessful cycles. This study aims to identify the pivotal clinical factors influencing the success of fresh embryo transfer of in vitro fertilization (IVF).
