Molar pregnancy

The pappalysins pregnancy associated plasma protein-A (PAPP-A) and -A2 (PAPP-A2) act as proteinases of insulin-like growth factor-1 (IGF-1) binding proteins, while stanniocalcin-2 (STC2) was identified as a pappalysin inhibitor. While there is some evidence from studies in children and adolescents, it is unclear whether these molecules are related to concentrations of IGF-1 and its binding proteins in adults. We investigated cross-sectionally the association of circulating PAPP-A, PAPP-A2 and STC2 with IGF-1 and its binding proteins (IGFBPs) in 394 adult pretest participants (20-69 years) of the German National Cohort Berlin North study center...

BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) is a rare ovulation induction therapy side effect. Nevertheless, it can occur in spontaneous ovulation cycles linked to multiple gestation, molar pregnancy, polycystic ovarian syndrome, and hypothyroidism. The pathogenesis of OHSS remains poorly understood. However, in recent studies, it has been observed that increased concentrations of thyroid-stimulating hormone (TSH) can potentially have stimulatory effects on the ovaries due to the homologous structure shared between TSH and gonadotropins...

Ionizable lipid nanoparticles (LNPs) have gained attention as mRNA delivery platforms for vaccination against COVID-19 and for protein replacement therapies. LNPs enhance mRNA stability, circulation time, cellular uptake, and preferential delivery to specific tissues compared to mRNA with no carrier platform. However, LNPs are only in the beginning stages of development for safe and effective mRNA delivery to the placenta to treat placental dysfunction. Here, we develop LNPs that enable high levels of mRNA delivery to trophoblasts in vitro and to the placenta in vivo with no toxicity...

OBJECTIVE: Although the systemic lupus (SLE) patient population is racially and ethnically diverse, many study populations are homogeneous. Further, data are often lacking on critical factors such as antiphospholipid (aPL) antibodies. We investigated livebirth rates in patients with SLE at Kaiser Permanente Northern California including race/ethnicity and aPL data. METHODS: Electronic health records of pregnancies with outcomes observed from 2011-2020 were identified among patients with SLE...

OBJECTIVE: This short communication demonstrates how short tandem repeat genotyping can identify the origin of gestational choriocarcinoma. MATERIALS AND METHODS: The origin of gestational choriocarcinoma in our three cases was determined using the short tandem repeats genotyping technique, which involved quantitative fluorescent PCR and fragmentation analysis. RESULTS: In Case 1 despite no medical history of molar pregnancy, DNA analysis indicated that the choriocarcinoma originated from a homozygous complete hydatidiform mole...

BACKGROUND: Consuming ultra-processed foods may increase exposure to phthalates, a group of endocrine disruptors prevalent in food contact materials. OBJECTIVES: Investigate associations between ultra-processed food intake and urinary phthalates during pregnancy, and evaluate whether ultra-processed foods mediate socioeconomic disparities in phthalate exposures. METHODS: In a socioeconomically diverse sample of 1031 pregnant women from the Conditions Affecting Neurocognitive Development and Learning in Early Childhood (CANDLE) Study in the urban South, the Block Food Frequency Questionnaire was administered and urinary phthalate metabolites were measured in the second trimester...

BACKGROUND: Dimethyl fumarate (DMF) has a favorable benefit-risk profile treating people with multiple sclerosis and should be used in pregnant women only if the potential benefits outweigh potential risks to the fetus. OBJECTIVE: Assess pregnancy outcomes in a completed international registry (TecGistry) of women with MS exposed to DMF. METHODS: TecGistry included pregnant women with MS exposed to DMF, with data collected at enrollment, 6-7 months gestation, 4 weeks after estimated due date, and at postpartum weeks 4, 12, and 52...

Uterine arteriovenous malformations (AVM) are rare and may be missed in routine clinical practice, often concealing their existence until dire consequences emerge. This potentially lethal condition can manifest abruptly, with torrential postabortal bleeding, as a grim reminder of its risky nature. Here, we present a rare case of para 1, living 1, abortion 2, initially subjected to dilatation and evacuation due to a missed abortion at a peripheral healthcare facility, subsequently developing torrential bleeding despite all the conservative measures...

INTRODUCTION: Hydatidiform mole is one of the gestational trophoblastic disease and comprises complete (CM) and partial moles (PM), which carries a risk of developing persistence disease, invasive mole or choriocarcinoma. MicroRNAs (miRNAs) have been discovered in various tissues, including neoplastic tissues. Its role in the pathogenesis of molar pregnancy or as biomarkers are still largely uncertain. The aim of this study is to identify the differentially expressed miRNAs in CM and PM...

BACKGROUND: Phthalates have been reported to impair fertility in various studies. However, evidence exploring the associations between phthalate metabolites in follicular fluid (FF) and reproductive outcomes is lacking. OBJECTIVES: To investigate the associations between phthalate metabolite concentrations in FF and in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes among women recruited from a fertility clinic. METHODS: We included 641 women undergoing IVF/ICSI treatment from December 2018 to January 2020...

Regardless of whether a pregnancy ends in abortion, miscarriage or ectopic pregnancy, fertility and sexual activity can resume quickly. For those who do not plan to become pregnant again immediately, effective contraception is therefore required. Although a contraceptive discussion and the offer to provide contraception is considered an integral part of abortion care, health care providers may not always offer this same standard of care to those whose pregnancy ends in miscarriage or ectopic due to sensitivities or assumptions around this and future fertility intentions...

A hydatidiform mole (HM) or molar pregnancy is the most common benign form of gestational trophoblastic disease characterized by a proliferation of the trophoblastic epithelium and villous edema. Hydatidiform moles are classified into two forms: complete and partial hydatidiform moles. These two types of HM present morphologic, histopathologic and cytogenetic differences. Usually, hydatidiform moles are a unique event, but some women present a recurrent form of complete hydatidiform moles that can be sporadic or familial...

Some health agencies have issued precautionary principle fish advisories to pregnant women based on the presence of methylmercury (MeHg) in fish that could possibly be harmful to the developing fetus. Fish, however, is a rich source of selenium (Se) and other nutrients essential for normal brain development. Selenium is also thought to have a key role in alleviating MeHg toxicity. We estimated the dietary Se and MeHg intakes and dietary Se:Hg molar ratios from the fish consumed in a high fish-eating pregnant cohort where no adverse associations of fish consumption and outcomes has been reported...

INTRODUCTION AND IMPORTANCE: Molar pregnancy is the most common type of gestational trophoblastic disease. It manifests as vaginal bleeding, accompanied by high levels of β-human chorionic gonadotropin (β-HCG). This case aims to highlight the importance of considering gestational trophoblastic disease as a potential diagnosis and its serious complications. CASE PRESENTATION: A 24-year-old female presented with vomiting, nausea, and no complaint of vaginal bleeding...

OBJECTIVES: This study aimed to shed new light on the potential detrimental effects on cementum and adjacent alveolar bone after chronic exposure to amoxicillin. METHODS: Six pregnant adult Albino rats were equally divided into two groups. Saline solution and amoxicillin (100 mg/Kg) were given to rats of control and amoxicillin group, respectively from the 13th to the 21st day of pregnancy. The same treatment was given to the pups till the 42nd day. The cementum of the first molar teeth and the surrounding alveolar bone were examined qualitatively by histopathological and scanning electron microscope, and quantitatively by energy dispersive X-ray spectroscopy and cone beam computed tomography...

Gestational trophoblastic disease encompasses a range of lesions, each culminating in varied clinical manifestations. Among these, the simultaneous occurrence of molar changes within the placenta and a viable fetus remains a particularly elusive and challenging presentation, posing intricate dilemmas for obstetricians. In this article, we delineate a distinct case involving a 21-year-old woman with a history of consanguineous marriage. She was referred from Médecins Sans Frontières to the Rafic Hariri University Hospital during her 19th week of gestation...

Hyperthyroidism due to gestational trophoblastic disease (GTD) is a rare but potentially life-threatening condition. Optimal perioperative management is crucial for favorable outcomes and prevention of thyroid storm. However, scarce data exist defining the ideal approach to this complex clinical presentation. This case report describes a first-time pregnant 32-year-old woman who was found to be biochemically hyperthyroid in the context of a 10-week gestation molar pregnancy. Despite her biochemical values, the patient remained clinically asymptomatic of her thyroid disease...

BACKGROUND: Endometrial stromal sarcoma (ESS) is extremely rare in pregnancy. It shares clinical and imaging features with more common pregnancy findings such as leiomyoma and molar gestations, which makes diagnosis challenging. CASE: A 36-year-old patient presented at 8 weeks and 1 day gestation for vaginal bleeding. An intrauterine pregnancy with an appropriately sized embryo with heart motion and a 9.5 cm complex uterine mass was found on ultrasound...

Gestational trophoblastic neoplasia (GTN) is a group of pregnancy-related disorders that arise from the cells of conception. They include gestational choriocarcinoma (CC), placental site trophoblastic tumor, and epithelioid trophoblastic tumor with these forms arising from a molar pregnancy, abortion, or a normal genetic pregnancy. Most cases of GTN are diagnosed when the serum hCG levels plateau or rise in patients being followed up after the diagnosis of hydatidiform mole but can also be suspected due to persistent vaginal bleeding after a normal pregnancy and delivery...
