Pregnancy loss

The bond with healthcare services is a crucial dimension in facilitating the maternal journey of lesbian and bisexual women couples. This study aimed to analyze the culturally constructed meanings regarding the bond with healthcare services and professionals by lesbian and bisexual women who experienced dual motherhood. It is a qualitative investigation grounded in interpretative anthropology. The research corpus was built based on in-depth interviews with 10 lesbian and bisexual women, aged 30 to 39 years...

BACKGROUND: Awareness of the age-related decline in fertility potential has increased the popularity of planned oocyte cryopreservation (POC). However, data regarding outcomes of POC, including rates of women returning to thaw oocytes, as well as pregnancy and live birth rates, are scarce and based mostly on small case series. OBJECTIVE AND RATIONALE: POC was defined as cryopreservation exclusively for prevention of future age-related fertility loss. The primary outcome was live birth rate per patient...

OBJECTIVES: To report the outcome of fetuses with a prenatal diagnosis of congenital lung malformation (CLM) diagnosed on ultrasound by performing a comprehensive assessment of these outcomes through a systematic review and meta-analysis. CONTENT: CLMs are a heterogeneous group of anomalies that involve the lung parenchyma and its bronchovascular structures. Their presentation and evolution are variable, from entirely asymptomatic lesions with sonographic regression in utero to hydropic fetuses requiring fetal therapy, intrauterine death or neonatal morbidity...

OBJECTIVE: The aim of the present study was to evaluate the effectiveness of a 12-month early postnatal lifestyle intervention program in women with gestational diabetes in a recent pregnancy. METHODS: This study was a prospective randomized intervention study conducted at a diabetes center in Hong Kong. Chinese women aged 18-45 years, who developed gestational diabetes mellitus (GDM) in their most recent pregnancy, were invited. Eligible women were randomized in 1:1 ratio at baseline (6-12 weeks postpartum), to standard care or lifestyle intervention (diet and physical activity) groups for 12 months...

BACKGROUND: Maternal overweight/obesity and excessive gestational weight gain (GWG) are frequently reported to be risk factors for obesity and other metabolic disorders in offspring. Cord blood metabolites provide information on fetal nutritional and metabolic health and could provide an early window of detection of potential health issues among newborns. The aim of the study was to explore the impact of maternal prepregnancy overweight/obesity and excessive GWG on cord blood metabolic profiles...

BACKGROUND: Cervical cerclage is the only effective treatment for cervical insufficiency, effectively preventing late miscarriage and preterm birth. The effectiveness and safety of emergency cervical cerclage (ECC) as an emergency treatment when the cervix is already dilated or when there is protrusion of the fetal membranes into the vagina remain controversial, especially in pregnancies at 24-28 weeks when the fetus is viable. There is still no consensus on whether emergency cervical cerclage should be performed in such cases...

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...

Cornual ectopic pregnancy, though rare, presents significant challenges in diagnosis and management. This case report details the clinical presentation and successful treatment of a 22-year-old primigravida experiencing symptoms of abdominal pain, nausea, and vomiting, ultimately diagnosed with an unruptured left cornual ectopic pregnancy. Employing a multidisciplinary approach involving clinical suspicion, beta-human chorionic gonadotropin (β-hCG) measurements, and transvaginal ultrasound findings, we underscored the importance of timely intervention to avert adverse outcomes...

BACKGROUND: Gestational diabetes insipidus (DI) is a very rare complication of pregnancy. We present a case of gestational DI combining two different types of DI. Case Presentation . A 39-year-old pregnant woman suddenly presented with thirst, polydipsia, and polyuria after 31 gestation weeks (GWs). Based on laboratory findings of hypotonic urine (78 mOsm/kgH2 O) with higher plasma osmolality (298 mOsm/kgH2 O) and higher serum sodium levels (149 mEq/L), gestational DI was suspected, and the clinical course was monitored without therapy until the results of a measurement of plasma arginine vasopressin (AVP) levels were available...

UNLABELLED: Seahorses, pipefishes, and seadragons are fishes from the family Syngnathidae that have evolved extraordinary traits including male pregnancy, elongated snouts, loss of teeth, and dermal bony armor. The developmental genetic and cellular changes that led to the evolution of these traits are largely unknown. Recent syngnathid genomes revealed suggestive gene content differences and provide the opportunity for detailed genetic analyses. We created a single cell RNA sequencing atlas of Gulf pipefish embryos to understand the developmental basis of four traits: derived head shape, toothlessness, dermal armor, and male pregnancy...

The adverse use of alcohol is a serious global public health problem. Maternal alcohol consumption during pregnancy usually causes prenatal alcohol exposure (PAE) in the developing fetus, leading to a spectrum of disorders known as fetal alcohol spectrum disorders (FASD) and even fetal alcohol syndrome (FAS) throughout the lifelong sufferers. The prevalence of FASD is approximately 7.7 per 1,000 worldwide, and is even higher in developed regions. Generally, Ethanol in alcoholic beverages can impair embryonic neurological development through multiple pathways leading to FASD...

Massive genotyping in cattle has uncovered several deleterious haplotypes that cause pre-term mortality. Holstein Haplotype 5 (HH5) is a deleterious haplotype present in the Holstein Friesian population that involves the ablation of the Transcription Factor B1 mitochondrial (TFB1M) gene. The developmental stage at which HH5 double-carrier (DC, homozygous) embryos or fetuses die remains unknown and this is a relevant information to estimate the economic losses associated to the inadvertent cross between carriers...

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...

BACKGROUND: Placenta accreta spectrum often leads to massive hemorrhage and even maternal shock and death. This study aims to identify whether cervical length and cervical area measured by magnetic resonance imaging correlate with massive hemorrhage in patients with placenta accreta spectrum. METHODS: The study was conducted at our hospital, and 158 placenta previa patients with placenta accreta spectrum underwent preoperative magnetic resonance imaging examination were included...

OBJECTIVES: To evaluate the implementation of mifepristone and misoprostol for medical management of early pregnancy loss (EPL) in emergency departments (EDs) by comparing efficacy, complication, and follow-up rates for patients treated in EDs to those in the Complex Family Planning (CFP) outpatient office. STUDY DESIGN: In COVID-19's first wave, we expanded medication management of EPL to our EDs. This retrospective study evaluated 72 patients receiving mifepristone and misoprostol for EPL from 4/1/2020-3/31/2021, comparing treatment success, safety outcomes, and follow-up rates by location...

Organophosphate esters (OPEs) are a class of chemicals now widely used as flame retardants and plasticizers after the phase-out of polybrominated diphenyl ethers (PBDEs). However, OPEs carry their own risk of developmental toxicity, which poses concern for recent birth cohorts as they have become ubiquitous in the environment. In this review, we summarize the literature evaluating the association between OPE exposure and maternal, perinatal, and child health outcomes. We included original articles investigating associations of OPE exposure with any health outcome on pregnant women, newborns, children, and adolescents...

BACKGROUND: First Nations Peoples endure disproportionate rates of stillbirth compared with non-First Nations Peoples. Previous interventions have aimed at reducing stillbirth in First Nations Peoples and providing better bereavement care without necessarily understanding the perceptions, knowledge and beliefs that could influence the design of the intervention and implementation. AIM: The aim of this review was to understand the perceptions, knowledge and beliefs about stillbirth prevention and bereavement of First Nations Peoples from the US, Canada, Aotearoa/New Zealand, and Australia...

Introduction There is no clear guidance for the optimal setting for dilation and curettage (D&C) for the management of first-trimester pregnancy failure. Identifying patients at risk of clinically significant blood loss at the time of D&C may inform a provider's decision regarding the setting for the procedure. We aimed to identify risk factors predictive for blood loss of 200mL or greater at the time of D&C. Methods  This is a retrospective cohort study of patients diagnosed with first-trimester pregnancy failure at gestational age less than 11 weeks who underwent surgical management with D&C at a single safety net academic institution between 4/2016 and 4/2021...

BACKGROUND: A diagnosis of Silver-Russell syndrome (SRS), a rare imprinting disorder responsible for foetal growth restriction, is considered for patients presenting at least four criteria of the Netchine-Harbison clinical scoring system (NH-CSS). Certain items of the NH-CSS are not assessable until the age of 2 years. The objective was to determine perinatal characteristics of children with SRS to allow an early diagnosis. METHODS: We retrospectively compared the perinatal characteristics of children with SRS ( n  = 17) with those of newborns small for gestational age (SGA) due to placental insufficiency (PI) ( n  = 21)...

Influenza A virus (IAV) infection in pregnancy resembles a preeclamptic phenotype characterised by vascular dysfunction and foetal growth retardation. Given that low dose aspirin (ASA) is safe in pregnancy and is used to prevent preeclampsia, we investigated whether ASA or NO-conjugated aspirin, NCX4016, resolve vascular inflammation and function to improve offspring outcomes following IAV infection in pregnant mice. Pregnant mice were intranasally infected with a mouse adapted IAV strain (Hkx31; 104 plaque forming units) and received daily treatments with either 200µg/kg ASA or NCX4016 via oral gavage...
