METHODS: Randomized controlled trial conducted among eligible clients seeking abortion between 13 and 20 weeks' gestation. Participants seeking in-facility abortion were randomized to receive care from a mid-level provider (nurse/midwife) or physician. The primary outcome was median time to expulsion with non-inferiority margin of -1...

Prediction of women at high risk of preeclampsia is important for prevention and increased surveillance of the disease. Current prediction models need improvement, particularly with regard to late-onset preeclampsia. Preeclampsia shares pathophysiological entities with cardiovascular disease; thus, cardiovascular biomarkers may contribute to improving prediction models. In this nested case-control study, we explored the predictive importance of mid-pregnancy cardiovascular biomarkers for subsequent preeclampsia...

OBJECTIVES: To assess the association between allostatic load in early pregnancy and sleep-disordered breathing (SDB) during pregnancy. METHODS: High allostatic load in the first trimester was defined as ≥ 4 of 12 biomarkers (systolic blood pressure, diastolic blood pressure, body mass index, cholesterol, low-density lipoprotein, high-density lipoprotein, high sensitivity C-reactive protein, triglycerides, insulin, glucose, creatinine, and albumin) in the unfavorable quartile...

Emerging research findings suggest that airborne particulate matter might be a risk factor for gestational diabetes mellitus (GDM). However, the concentration-response relationships and the susceptible time windows for different types of particulate matter may vary. In this retrospective analysis, we employ a novel robust approach to assess the crucial time windows regarding the prevalence of GDM and to distinguish the susceptibility of three GDM subtypes to air pollution exposure. This study included 16,303 pregnant women who received routine antenatal care in 2018-2021 at the Maternal and Child Health Hospital in Chongqing, China...

BACKGROUND: Hyperglycemia during pregnancy leads to adverse maternal and fetal outcomes. Thus, strict monitoring of blood glucose levels is warranted. This study aims to determine the association of early to mid-pregnancy HbA1c levels with the development of pregnancy complications in women from three countries in South Asia and Sub-Saharan Africa. METHODS: We performed a secondary analysis of the AMANHI (Alliance for Maternal and Newborn Health Improvement) cohort, which enrolled 10,001 pregnant women between May 2014 and June 2018 across Sylhet-Bangladesh, Karachi-Pakistan, and Pemba Island-Tanzania...

OBJECTIVES: The incidence of cervical cancer increases every year during pregnancy. Cervical cytology in pregnant women has a unique morphology and liquid-based cytology methods are prone to cause false positives. The aim of this study was to investigate the serum cytokeratin 19 fragment antigen 21-1 (CYFRA21-1) and squamous cell carcinoma associated antigen (SCC-Ag) concentrations in healthy pregnant women during pregnancy and to assess their diagnostic value for cervical cancer in pregnancy...

OBJECTIVE: To analyze the effectiveness of cerclage in twin pregnancies with a short cervix. STUDY DESIGN: Retrospective cohort study performed in two University Institutions in Valencia (Spain) with two different protocols for the management of asymptomatic dichorionic diamniotic twin pregnancies with mid-trimester cervical length ≤ 25 mm: treatment with indomethacin, antibiotics and cerclage (cerclage group) (N = 43) versus expectant management (control group) (N = 37)...

OBJECTIVE: The aim of this study was to investigate the effects of exercise combined with cognitive behavioral therapy (CBT) on anxiety and quality of life in pregnant women. METHODS: This study adopted a prospective randomized controlled trial design, and divided 60 pregnant women in the first and second trimesters into two groups. The control group received routine prenatal education, and the experimental group added moderate exercise and CBT on the basis of routine prenatal education...

BACKGROUND: Relatively little is known about the immediate and prospective neurodevelopmental impacts of joint exposure to multiple metals (i.e., metal mixtures) in early childhood. OBJECTIVES: To estimate associations of early childhood (∼3 years of age) blood metal concentrations with cognitive test scores at early and mid-childhood (∼8 years of age). METHODS: We studied children from the Project Viva cohort. We measured erythrocyte concentrations of seven essential (Co, Cu, Mg, Mn, Mo, Se, and Zn) and eight non-essential metals (As, Ba, Cd, Cs, Hg, Pb, Sn, and Sr) in early childhood blood samples...

INTRODUCTION: Emergency cervical cerclage is a recognized method for preventing mid-trimester pregnancy loss and premature birth; however, its benefits remain controversial. This study aimed to establish preoperative models predicting preterm birth and gestational latency following emergency cervical cerclage in singleton pregnant patients with a high risk of preterm birth. MATERIAL AND METHODS: We retrospectively reviewed data from patients who received emergency cerclage between 2015 and 2023 in three institutions...

BACKGROUND: Changes in bone metabolism during pregnancy have not received sufficient attention because of the lack of effective screening tools. Bone turnover markers (BTMs) could reflect the changes of bone metabolism. Currently, reference intervals for bone metabolism during normal pregnancy are inconclusive. This study aimed to determine reference intervals for BTMs in pregnant women taking prenatal care and to facilitate clinical research on diseases affecting bone metabolism during pregnancy...

AIMS AND OBJECTIVES: To determine utilization of spot urinary albumin/creatinine ratio (UACR) to predict subsequent development of preeclampsia, measured between 17 and 24 weeks of gestational age in asymptomatic antenatal woman and determine their maternal and neonatal outcomes. INTRODUCTION: In preeclampsia the basic pathology is generalized endothelial dysfunction. It causes glomerular endotheliosis which leads to proteinuria, decreased glomerular filtration rate and renal blood flow...

In this report, we describe a 28-year-old woman, with unicornuate uterus and multiple mid-trimester losses, with two failed Mc Donald's cerclage. She presented to us as a case of recurrent pregnancy losses with history suggestive of cervical incompetence and on detailed investigation was found to be ANA and anti-cardiolipin antibody positive and Rh negative. We performed an interval laparoscopic cervical cerclage for her and were able to successfully deliver her at 35 + 3 weeks with a healthy baby by caesarean section after previous five pregnancy losses and two failed Mc Donald's cerclage...

BACKGROUND: Depression during pregnancy is a common complication that can negatively affect fetal health and birth outcomes. Cortisol is believed to be a key mediator of this association. Although pregnancy entails a natural increase in cortisol levels, preclinical depression could alter its circadian rhythm, producing excessively high overall diurnal cortisol levels that might be harmful for the fetus and future offspring development. OBJECTIVES: Using a prospective longitudinal design, we aimed to study (i) trimestral cortisol circadian rhythm and its overall levels throughout pregnancy in healthy women, (ii) the extent to which maternal depressive symptoms influence both cortisol rhythmicity and overall levels, and (iii) the possible adverse consequences of elevated maternal cortisol on the offspring's weight and gestational age at birth...

Ultrasound-indicated cerclage (UIC) is recommended to prevent spontaneous preterm birth (sPTB) in women with a short cervix at mid-trimester and a history of PTB. We assessed the factors related to sPTB after UIC and determined the corresponding risks. This retrospective cohort study was conducted at a university hospital. UIC was performed between 15 and 26 weeks of gestation in women with a cervical length of <2.5 cm. Univariate and multivariate analyses were used to examine factors associated with sPTB after UIC...

BACKGROUND: Cavernous haemangiomas are benign vascular tumours that are known to occasionally involve the female genital tract, including the uterus. They are often underdiagnosed during pregnancy, although they can also lead to severe postpartum or antepartum haemorrhage. OBJECTIVES: Describe our case of an uncommon second-trimester pregnancy loss in a woman with a diffuse cavernous haemangioma of the uterus and cervix and review the wider literature. METHODS: The review was conducted using MEDLINE, Scopus and PubMed electronic databases from beginning of the database to May 2023, using the following keywords: arteriovenous malformation; cavernous haemangioma/hemangioma; uterine neoplasms; pregnancy complications; abnormal vaginal bleeding...

BACKGROUND: The examination of 24-hour urinary total protein excretion is an essential parameter used for evaluating renal function and early detection of gestational complications. However, data on reference ranges of 24-hour urinary total protein excretion in normal pregnancy are scarce. OBJECTIVE: The objective was to determine reference ranges for 24-hour urinary total protein excretion in a population with uncomplicated singleton pregnancies using a standard method for urinary total protein...

OBJECTIVE: Impaired elasticity of aorta has been observed in fetuses with congenital cardiac disease, while the orientation of left ventricle outflow tract has been found to influence the blood flow in the ascending aorta. Therefore, the objective of this study is to examine the left ventricle inflow and outflow tract angle (LIOA) in healthy fetuses. METHOD: A total of 668 fetuses were enrolled in this prospective study. The LIOA were measured with two-line method at left ventricle inflow and outflow tract view...

BACKGROUND: Poor dietary diversity and undernutrition is a major public health concern for pregnant mothers. Optimal dietary diversity is essential during pregnancy since nutritional deficiencies may have a significant impact on both the mother's and the fetus's health. Pregnant women in Ambo district had inadequate dietary diversity and were undernourished, but their status during the first trimester of pregnancy was not known. As a result, the objective of this research was to assess the dietary diversity, nutritional status, and associated factors among pregnant women in the Ambo district...
