High risk pregnancy

BACKGROUND: A low socioeconomic status is associated with a vulnerable health status (VHS) through the accumulation of health-related risk factors, such as poor lifestyle behaviors (eg, inadequate nutrition, chronic stress, and impaired health literacy). For pregnant women, a VHS translates into a high incidence of adverse pregnancy outcomes and therefore pregnancy-related inequity. We hypothesize that stimulating adequate pregnancy preparation, targeting lifestyle behaviors and preconception care (PCC) uptake, can reduce these inequities and improve the pregnancy outcomes of women with a VHS...

The developmental origins of health and disease concept highlights the impact of early environments on chronic non-communicable diseases like diabetes, cardiovascular disease, and cancer. Studies using animal models have investigated how maternal factors such as undernutrition, overnutrition, obesity, and exposure to chemicals or hypoxia affect fetal development and offspring health, leading to issues like low birth weight, high blood pressure, dyslipidemia, and insulin resistance. Given the increasing prevalence of overweight and obesity among reproductive-age women, effective interventions are critical...

OBJECTIVE: To establish a haplotype-based noninvasive prenatal testing (NIPT) workflow for single-gene recessive disorders that adapt to dizygotic (DZ) twin pregnancies. METHOD: Twin pregnancies at risk of Duchenne muscular dystrophy, Becker muscular dystrophy, hemophilia B, spinal muscular atrophy, phenylketonuria, and nonsyndromic hearing loss were recruited. For subsequent analysis, capture sequencing targeting highly heterozygotic single nucleotide polymorphism sites was conducted...

INTRODUCTION: This study was aimed at establishing a pregnancy-specific lipid reference interval (RI) in pregnant women in a single-centre in the Beijing area of China, simultaneously exploring the predictive value of lipid levels in early pregnancy for gestational diabetes mellitus (GDM). MATERIAL AND METHODS: From October 2017 to August 2019, Peking University International Hospital established records for 1588 pregnant women, whose lipid profiles were determined during the first and third trimesters...

OBJECTIVE: Obstructive sleep apnea (OSA) affects maternal and neonatal health during pregnancy. This study aimed to identify characteristics and comorbidities associated with sleep clinic referral in high-risk pregnancies with Body Mass Index (BMI) ≥35 kg/m2 . METHOD: Retrospective cohort study for individuals in a high-risk pregnancy clinic at a tertiary Australian hospital from 1 January to 31 December 2020 with BMI≥35 kg/m2 . The primary outcome measure was sleep clinic referral...

OBJECTIVE: Membrane stripping in group B streptococcus (GBS) carriers poses an increased risk of inadequate antibiotic prophylaxis, potentially due to accelerated labor, thereby potentially impacting the management of GBS colonization during delivery. We compared the adequacy of intrapartum antibiotic prophylaxis between pregnant women colonized with GBS, who underwent membrane stripping and those who did not. The study aimed to determine whether the performance of membrane stripping, by potentially shortening labor duration, increases the risk of inadequate antibiotic prophylaxis dispensation...

Pregnant people with comorbid posttraumatic stress disorder (PTSD) and substance use disorder (SUD) constitute a highly vulnerable population. PTSD and SUD confer risks to both the pregnant person and the fetus, including a host of physical and mental health consequences. When PTSD and SUD co-occur, potential negative impacts are amplified, and the symptoms of each may exacerbate and maintain the other. Pregnancy often increases engagement in the healthcare system, presenting a unique and critical opportunity to provide PTSD and SUD treatment to birthing people motivated to mitigate risks of losing custody of their children...

Ischemic heart disease is an important cause of heart failure in pregnancy. Involvement of a cardio-obstetrics team is crucial for managing high-risk pregnant patients with cardiovascular disease. We present a case of cardiogenic shock in a pregnant woman unmasking underlying multivessel obstructive coronary artery disease.

INTRODUCTION: A cross-sectional study retrospectively evaluating the perceived usefulness of attending a multi-disciplinary, roundtable, educational prenatal clinic for mothers expecting children with myelomeningocele is presented. METHODS: Mothers who currently have children with SB completed a survey which evaluated their overall preparedness, spina bifida education, delivery plans, surgical expectations, and expectations in terms of quality of life and development...

BACKGROUND: Cardiovascular diseases (CVDs) are currently the leading cause of maternal death in Western countries. Although multidisciplinary cardio-obstetric teams are recommended to improve the management of pregnant women with CVD, data supporting this approach are scarce. AIMS: To describe the characteristics and outcomes of pregnant patients with CVD managed within the cardio-obstetric programme of a tertiary centre. METHODS: We included every pregnant patient with history of CVD managed by our cardio-obstetric team between June 2017 and December 2019, and collected all major cardiovascular events (death, heart failure, acute coronary syndromes, stroke, endocarditis and aortic dissection) that occurred during pregnancy, peripartum and the following year...

The objective of this study was to evaluate the association of maternal cardiometabolic markers trajectories (glucose, triglycerides (TG), total cholesterol, systolic blood pressure (SBP) and diastolic blood pressure (DBP)) with estimated fetal weight trajectories and birth weight in Mexican pregnant women without medical complications. Cardiometabolic marker trajectories were characterized using group-based trajectory models. Mixed-effect and linear regression models were estimated to assess the association of maternal trajectories with estimated fetal weight and birth weight...

The objective was to compare differences in reproductive performance for dairy cows grouped based on the combination of data for predictors available during the prepartum period and before the end of the VWP, automated estrus alerts (AEA) during the VWP, and the combination of both factors. In a cohort study, data for AEA and potential predictors of the percentage of cows that receive insemination at detected estrus (AIE) and pregnancies per AI (P/AI) for first service, and the percentage of cows pregnant by 150 DIM (P150) were collected from -21 to 49 DIM for lactating Holstein cows (n = 886)...

BACKGROUND: Prenatal maternal distress can negatively affect pregnancy outcomes, yet its impact on the offspring's brain structure and function remains unclear. This systematic review summarizes the available literature on the relationship between prenatal maternal distress and brain development in fetuses and infants up to 12 months of age. METHODS: We searched Central, Embase, MEDLINE, PsycINFO, and PSYNDEXplus for studies published between database inception and December 2023...

OBJECTIVE: To examine the prenatal profiles of pregnancies affected by an atypical chromosomal aberration, focusing on pathogenic copy number variants (pCNVs). Further, we wanted to quantify the performance of combined first-trimester screening (cFTS) and a second-trimester anomaly scan in detecting these conditions. Finally, we aimed to estimate the consequences of a policy of using non-invasive prenatal testing (NIPT) rather than invasive testing with chromosomal microarray (CMA) to manage pregnancies identified as high risk from cFTS...

Gestational diabetes is characterized by hyperglycaemia diagnosed during pregnancy. Gestational and pregestational diabetes can have deleterious effects during pregnancy and perinatally. The baby's weight is frequently above average and might reach macrosomia (≥ 4 kg), which can reduce pregnancy time causing preterm births, and increase foetal-pelvic disproportion which often requires delivery by caesarean section. Foetal-pelvic disproportion due to the baby's weight can also cause foetal distress resulting in lower Apgar scores...

BACKGROUND: Mother-to-child transmission is the primary cause of HIV cases among children. Antiretroviral therapy (ART) plays a critical role in preventing mother-to-child transmission and reducing HIV progression, morbidity, and mortality among mothers. However, after more than two decades of ART during pregnancy, the comparative effectiveness and safety of ART medications during pregnancy are unclear, and existing evidence is contradictory. This study aimed to assess the effectiveness and safety of different ART regimens among pregnant women living with HIV at preconception or during pregnancy...

BACKGROUND: Birthing people with de novo postpartum hypertensive disorders remain among the highest risk for severe maternal morbidity. Randomized controlled trials demonstrate a benefit to oral loop-diuretics in decreasing postpartum hypertensive morbidity in patients with an antenatal diagnosis of preeclampsia. It is not known whether this same therapy benefits patients at risk for new-onset postpartum hypertension OBJECTIVE: To evaluate whether oral furosemide can reduce risk for de novo postpartum hypertension (dnPPHTN) among high-risk birthing people by reducing post-delivery blood pressure...

INTRODUCTION: Vaccination during pregnancy protects both the mother and the foetus from vaccine-preventable diseases. However, uptake of the recommended vaccines (influenza, pertussis, COVID-19) by pregnant women remains low in Europe and the USA. Understanding the reasons for this is crucial to inform strategies to increase vaccination rates in pregnant women. This qualitative systematic review aimed to identify the barriers and facilitators to vaccination against influenza, pertussis/whooping cough and COVID-19 during pregnancy and identify possible strategies to increase vaccination rates...

OBJECTIVES: Universal opt-out antenatal screening for Hepatitis C virus (HCV) is not currently recommened and it is recommended that maternity services offer risk-based testing. We aimed to investigate antenatal HCV testing and adherence to testing guidance. METHODS: A cross-sectional survey was circulated to maternity service providers between November-December 2020 which included testing policy, training for healthcare staff, and management of women found to be HCV positive...

OBJECTIVE: The study aimed to evaluate the utility and safety of ancillary maneuvers during oocyte retrieval for patients with endometrioma that makes ovum pick-up hard due to poor ovarian surgical accessibility. PATIENTS AND METHODS: Cases of 251 women with ovarian endometriomas undergoing in vitro fertilization (IVF) in our infertility unit were retrospectively analyzed to evaluate the clinical IVF cycle outcomes after oocyte retrieval. Controls (n = 251) were age-matched women without endometriomas who underwent an uncomplicated oocyte retrieval...
