Objectives: Solid organ transplants (SOT), including kidney, liver, heart, lung, and pancreas transplants, have become more common in the last few decades. However, few population-based studies have attempted to comprehensively quantify severe maternal morbidity (SMM) and maternal mortality associated with pregnancies among recipients of SOTs. This study aimed to determine the proportion of women with SOTs among all delivering women, and to quantify the rates of SMM and maternal mortality associated with SOT.

Background: Increases in maternal age, obesity and other factors have led to an increase in hypertension, diabetes, and other chronic diseases among pregnant women. However, the impact of chronic diseases on maternal mortality has not been adequately studied.

Objectives: To quantify the contribution of maternal mortality associated with chronic disease to maternal mortality in the United States in 1999-2002 and 2018-2022.

Objectives: Congenital cytomegalovirus (CMV) infection, resulting from maternal-fetal transmission of CMV, poses a substantial risk to maternal and child health. It is the most prevalent congenital viral infection, and the prevention and management of this condition rely heavily on the knowledge and awareness of healthcare professionals.

Methods: This cross-sectional survey was conducted between March 1, 2023, and August 31, 2023, across multiple tertiary centers in various Saudi Arabian cities.

Article Synopsis
  • Maternal mortality ratios (MMR) in the U.S. increased significantly from 1999-2021, rising from 9.60 to 23.5 per 100,000 live births, with higher increases noted in states with already high MMRs.
  • The study found that decreases in MMRs due to clear obstetric causes were similar across low and high MMR states, but the rise in deaths from less specific causes was much more pronounced in high-MMR states like Texas than in lower-MMR ones like California.
  • Overall, increases in MMRs from less-specific/potentially incidental causes were observed across all racial and ethnic groups, indicating a troubling trend in maternal health disparities.

The ex-utero intrapartum treatment (EXIT) is a rare surgical procedure performed in cases of expected postpartum fetal airway obstruction. This procedure technique lies in a safe establishment of a patent airway during labor in anticipation of a critical respiratory event, without the interruption of maternal-fetal circulation. Anesthetic management in the EXIT procedure is substantially different from that of the standard cesarean delivery and its main goals include uterine relaxation, fetal anesthesia, and placental blood flow preservation.

Several adverse maternal outcomes have been linked to the excessive consumption of caffeine during pregnancy. Tea is an important source of caffeine. Hypertensive disorders of pregnancy (HDP) are common pregnancy complications with unfavorable maternal and fetal complications.

Article Synopsis
  • Maternal mortality rates in the U.S. have nearly doubled from 2018 to 2021, rising from 17.4 to 32.9 deaths per 100,000 live births, potentially influenced by factors beyond obstetrical issues.
  • This study examines whether these rising rates are due to changes in obstetrical factors, maternal health conditions, or shifts in how maternal mortality is tracked and reported.
  • Results show a 144% increase in maternal deaths from 1999-2002 to 2018-2021 across all racial and ethnic groups, with notable rises in both direct and indirect obstetrical deaths.

Background: The annual prevalence of gestational diabetes mellitus-characterized by an increase in blood glucose in pregnant women-has been increasing worldwide. The goal of this study was to evaluate the expression of glucose transporter 1 (GLUT1) and glucose transporter 3 (GLUT3) in the placenta of women with gestational diabetes mellitus.

Methods: Sixty-five placentas from women admitted to the King Saud University Medical City, Riyadh, Saudi Arabia, were analyzed; 34 and 31 placentas were from healthy pregnant women and women with gestational diabetes, respectively.

Background And Objectives: Although racial and ethnic disparities in adverse birth outcomes have been well documented, it is unknown whether such disparities diminish in women who use medically assisted reproduction (MAR). We examined differences in the association between maternal race and ethnicity and adverse birth outcomes among women who conceived spontaneously and those who used MAR, including assisted reproduction technology (ART), eg, in-vitro fertilization, and also non-ART MAR, eg, fertility drugs.

Methods: We conducted a population-based retrospective cohort study using data on all singleton births (N = 7 545 805) in the United States from 2016 to 2017.

Objectives: The objective of this study was to measure the association between uterine fibroids (UFs) and several risk factors (parity, miscarriage, diabetes, hypertension, physical activity, smoking, family history of UF and contraceptive pill use) among Saudi women.

Methods: A case-control study was conducted in 478 women at two medical centers in Riyadh. Cases were confirmed by ultrasound.

Background: The majority of previous studies on severe preeclampsia, eclampsia, and hemolysis, elevated liver enzymes, and low platelet count syndrome were hospital-based or included a relatively small number of women. Large, population-based studies examining gestational age-specific incidence patterns and risk factors for these severe pregnancy complications are lacking.

Objective: This study aimed to assess the gestational age-specific incidence rates and risk factors for severe preeclampsia, hemolysis, elevated liver enzymes, and low platelet count syndrome, and eclampsia.

Rigorous studies carried out by the National Center for Health Statistics show that previously reported increases in maternal mortality rates in the United States were an artifact of changes in surveillance. The pregnancy checkbox, introduced in the revised 2003 death certificate and implemented by the states in a staggered manner, resulted in increased identification of maternal deaths and in reported maternal mortality rates. This Commentary summarizes the findings of the National Center for Health Statistics reports, describes temporal trends and the current status of maternal mortality in the United States, and discusses future concerns.

Background: The management of pregnant women with sickle cell disease (SCD) poses a major challenge for maternal healthcare services owing to the potential for complications associated with morbidity and mortality. Trustworthy evidence-based clinical practice guidelines (CPGs) have a major impact on the positive outcomes of appropriate healthcare. The objective of this study was to critically appraise the quality of recent CPGs for SCD in pregnant women.
