Maternal collapse

Investigating the genetic factors influencing human birth weight may lead to biological insights into fetal growth and long-term health. Genome-wide association studies of birth weight have highlighted associated variants in more than 200 regions of the genome, but the causal genes are mostly unknown. Rare genetic variants with robust evidence of association are more likely to point to causal genes, but to date, only a few rare variants are known to influence birth weight. We aimed to identify genes that harbour rare variants that impact birth weight when carried by either the fetus or the mother, by analysing whole exome sequence data in UK Biobank participants...

Sudden unexpected postnatal collapse (SUPC) of healthy newborns is a catastrophic event caused by cardiorespiratory collapse in a healthy newborn. The most common cause of SUPC is poor positioning of the newborn during skin-to-skin contact or breastfeeding when the newborn is not being observed by a health professional, attentive parent, or caretaker. Maternal/newborn health care professionals need to know about the essential information, definitions, incidence, risk factors, clinical presentation, outcomes, and prevention and management strategies to minimize the occurrence and impact of SUPC...

The impact of conflict and crisis on maternal and child health underscores the need for reliable research in vulnerable populations. Lebanon, amidst ongoing economic collapse, political instability, and healthcare system strain, offers a case study for exploring these impacts, particularly on preterm babies and their development. This study aims to assess the feasibility of establishing a prospective cohort of mothers and their full-term and preterm babies in Lebanon, examining the association between social determinants, preterm birth, and developmental outcomes amidst the nation's multifaceted crises...

BACKGROUND: Continuous glucose monitoring (CGM) has facilitated the evaluation of dynamic changes in glucose throughout the day and their effect on fetal growth abnormalities in pregnancy. However, studies of multiple CGM metrics combined and their association with other adverse pregnancy outcomes are limited. OBJECTIVE: Our goals were to 1) use machine-learning techniques to identify discrete glucose profiles based on weekly CGM metrics in pregnant individuals with pregestational diabetes and, 2) investigate their association with adverse pregnancy outcomes...

BACKGROUND: Early morphologic ultrasound, generally carried out in case of atypical first trimester serum markers (PAPP-A and/or free hCGβ <0.30 MoM), has not been re-evaluated since the possibility of performing a cell-free fetal DNA analysis in this indication. Our objective was to evaluate the usefulness of early morphological ultrasound in case of atypical profile of serum markers performed in association with Non-Invasive Prenatal Testing (NIPT). METHODS: This was a single-center retrospective study in a tertiary maternity...

OBJECTIVES: To synthesize the current evidence of maternal point-of-care ultrasound (POCUS) in obstetrics. A scoping review was conducted using PubMed, Clinicaltrials.gov, and the Cochrane library from inception through October 2023. METHODS: Studies were eligible for inclusion if they described the use of POCUS among obstetric or postpartum patients. Two authors independently screened all abstracts. Quantitative, qualitative, and mixed-methods studies were eligible for inclusion...

BACKGROUND AND OBJECTIVES: Spinal anesthesia is the technique of choice for elective cesarean section with a prominent side effect of postspinal anesthesia hypotension (PSH). This needs an early prediction to avoid feto-maternal complication. This study aimed to assess the diagnostic accuracy of perfusion index (PI) and inferior vena cava collapsibility index (IVCCI) in the prediction of PSH. MATERIAL AND METHODS: Thirty parturients of American Society of Anesthesiologists Physical Status (ASA-PS) 1 and two undergoing cesarean delivery participated in the study...

Supporting optimal newborn nutrition and the positive maternal-infant relationship, while encouraging safe sleep practices, are essential components of maternal and newborn care in the hospital setting following birth. Breastfeeding is widely recognized as best practice to support the nutritional needs and well-being of the infant, and recommendations have been developed by the World Health Organization (WHO), the American Academy of Pediatrics (AAP) and the US Centers for Disease Control (CDC) to encourage and successfully support breastfeeding efforts prior to hospital discharge...

BACKGROUND: Healthy parturients may experience pulmonary edema and disturbed cardiac function during labor. We aimed to evaluate the extravascular lung water (EVLW), intravascular volume, and cardiac function of normal parturients during spontaneous vaginal delivery by bedside ultrasound. And to explore the correlation between EVLW and intravascular volume, cardiac function. METHODS: This was a prospective observational study including 30 singleton-term pregnant women undergoing spontaneous vaginal delivery...

Amniotic fluid embolism (AFE) is a rare, sudden, and catastrophic complication of pregnancy that can result in cardiopulmonary arrest, potentially leading to death. The pathophysiology of an AFE includes an inflammatory and coagulopathic response due to fetal materials entering maternal circulation with the hallmark triad of symptoms: acute respiratory distress, cardiovascular collapse, and coagulopathy. Management of AFE should include high-quality cardiopulmonary resuscitation, immediate delivery of the fetus if applicable, early intubation to provide adequate oxygenation and ventilation, fluid volume resuscitation, and ongoing evaluation of coagulopathy...

Laryngomalacia (LM) is defined as the collapse of supraglottic structures during inspiration, resulting in intermittent airflow impedance and associated stridor. LM is the most prevalent cause of congenital stridor in newborns. The aim of this study is to determine the features and associated comorbidities of LM in Saudi Arabia and to delineate the diagnostic and therapeutic measures used, based on the severity of the case and related comorbidities. This is a three-year retrospective study of children diagnosed with LM and treated in the pediatric otorhinolaryngology outpatient clinic at Maternity and Children Hospital, Dammam, Saudi Arabia, between January 2018 and January 2022...

OBJECTIVE: Amniotic fluid embolism is one of the most serious pregnancy complications. It can cause sudden maternal collapse with high mortality and morbidity. We present a case report regarding the important of prompt decision making and multidisciplinary team work for management of amniotic fluid embolism to yield favorable maternal and neonatal outcome. CASE REPORT: This is a 35-year-old, gravida 2, para 1, woman underwent labor induction at gestational age of 37 + 6 weeks due to elective induction...

OBJECTIVE: Spinal anesthesia-induced hypotension (SAIH) is relatively common in pregnant women and has serious maternal and fetal side effects. In patients who are hypovolemic during spinal anesthesia, there may be a significant decrease in blood pressure caused by the decrease in preload. Subclavian vein sonography is a useful method for evaluating preoperative intravascular volume status. This study aimed to evaluate the efficacy of the pre-operative subclavian vein or infraclavicular axillary vein (SCV-AV) collapsibility index for predicting SAIH in cesarean-section (C-section)...

Integrated healthcare systems are continually pitched as major contributors towards better distribution of health outcomes and enhanced well-being. Under emergency conditions, integrated healthcare services can guarantee better access to the target population. In recent years, several crises, i.e., economic collapse, the fuel crisis, the Beirut blast, a large refugee population, and the COVID-19 pandemic, in Lebanon have led to a major shift in the health-seeking behavior of the communities, with preventive services being downprioritized despite being available and curative healthcare services being sought out as late as possible...

BACKGROUND: Diaphragmatic hernia (DH) is extremely rarely described during pregnancy. Due to the rarity, there is no diagnostic or treatment algorithm for DH in pregnancy. AIM: To summarize and define the most appropriate diagnostic methods and therapeutic options for DH in pregnancy based on scarce literature. METHODS: Literature search of English-, German-, Spanish-, and Italian-language articles were performed using PubMed (1946-2021), PubMed Central (1900-2021), and Google Scholar...

Amniotic fluid embolism is a rare complication of peripartum. It is caused by the entry of fetal components into the maternal systemic circulation. There are 2 main types: typical; it presents with the triad of hemodynamic collapse, respiratory distress and disseminated intravascular coagulation type coagulopathy, while atypical; disseminated intravascular coagulation does not occur. SARS CoV-2 infection causes coagulopathy due to the alteration of Virchow's triad and coagulation factors. We present the case of a 21-year-old pregnant woman who consulted for premature rupture of membranes, with an indication for cesarean section, and during surgery presented bradycardia, hypotension, and desaturation until cardiorespiratory arrest...

Pulmonary embolism (PE) in pregnancy accounts for 10% of maternal deaths in the United States. As maternal morbidity and mortality continue to increase, it is imperative for all specialties interfacing with pregnant patients to understand the current research and guidelines surrounding risk stratification, diagnosis, and treatments of PE in pregnancy. Given the complexity of high-risk pregnancy-associated PE (PA-PE), that is, which is associated with hemodynamic instability or collapse, and the rising popularity of new technologies to treat high-risk PA-PE in the nonpregnant population, this review aims to emphasize the differences in diagnosis, risk stratification, and management of the pregnant and nonpregnant PE patients...

We agree with Drs. Rollin, Krishnamurthy and Weerahandi1 that race is a social construct and has been used in medicine and research to explain differences in outcomes that are more appropriately attributed to inequities in health care and social determinants of health due to systemic racism. In our paper we explicitly state in the discussion that our findings of increased maternal morbidity for individuals who identify as non-Hispanic Black reflect "implicit bias, structural racism, and quality of care in obstetrics"...

PURPOSE OF REVIEW: Respiratory syncytial virus (RSV) remains a leading cause of mortality and morbidity worldwide. RSV seasonality was disrupted by COVID-19-associated nonpharmaceutical interventions (NPIs). We review RSV seasonality, molecular epidemiology, clinical manifestations, and community awareness to inform future prevention strategies. RECENT FINDINGS: An initial reduction of RSV disease observed with NPIs, and subsequent global resurgence was associated with a collapse in genetic diversity...

Early pregnancy ultrasound must satisfy objective criteria to make a safe diagnosis of miscarriage. The differential diagnosis of low-lying gestational sac includes cervical stage of miscarriage and cervical and caesarean scar ectopic pregnancies. Misdiagnosis can lead to significant maternal morbidity. We describe a pregnancy in a 36-year-old primiparous woman where ultrasound findings of a low-lying gestation sac satisfied criteria for miscarriage; however, dilatation and curettage of pregnancy contents resulted in brisk cervical bleeding...
