OBJECTIVE: Severe motor vehicle accidents involving pregnant women can result in fetal and neonatal death. We describe a case in which fetal death occurred due to relatively mild seatbelt injuries and present the characteristic magnetic resonance imaging (MRI) findings of the placenta. CASE REPORT: A 26-year-old primigravid woman at 20 weeks gestation was involved in an automobile accident. Although she suffered only a seatbelt injury, fetal death subsequently occurred...

BACKGROUND: Two-dimensional (2D) ultrasound quality has improved in recent years. Quantification of cardiac dimensions is important to screen and monitor certain fetal conditions. We assessed the feasibility and reproducibility of fetal ventricular measures using 2D echocardiography, reported normal ranges in our cohort, and compared estimates to other modalities. METHODS: Mass and end-diastolic volume were estimated by manual contouring in the four-chamber view using TomTec Image Arena 4...

BACKGROUND: Children with inherited bone marrow failure syndromes (IBMFSs) may be symptomatic in utero, resulting in maternal and fetal problems during the pregnancy. Subsequent pregnancies by their mothers should be considered "high risk". METHODS: We retrospectively analyzed outcomes of 575 pregnancies in 165 unaffected mothers of offspring with Fanconi anemia (FA), dyskeratosis congenita (DC), Diamond-Blackfan anemia (DBA), and Shwachman-Diamond syndrome (SDS) for events noted during pregnancy, labor, and delivery...

Introduction Internationally, there is debate on the safety of different birth settings inside and outside of hospitals. Low-risk women in Germany can choose where they give birth, and out-of-hospital births are especially necessary in regions lacking infrastructure. To date, national studies are required. Materials and Methods We investigated planned out-of-hospital (OH) and hospital births in Lower Saxony, Germany, in 2005. Women with a singleton fetus in the vertex position were included once they reached 34+0 gestational weeks...

We illustrate a case of giant placental chorioangioma presenting at 20 weeks of gestation. Subsequent monitoring revealed enlargement of the lesion, associated with fetal anemia and cardiac failure, prompting in utero intervention. Amnioreduction followed by percutaneous embolization of the tumour with enbucrilate:Lipiodol Ultra-Fluid™ at a dilution of 1:5 was successfully performed. No repeat intervention or additional supportive measures were required throughout pregnancy and the baby was delivered at 36 weeks of gestation, following spontaneous labour...

The formation of a protein corona around nanoparticles can influence their toxicity, triggering cellular responses that may be totally different from those elicited by pristine nanoparticles. The main objective of this study was to investigate whether the species origin of the serum proteins forming the corona influences the in vitro toxicity assessment of silica nanoparticles. Coronas were preformed around nanoparticles before cell exposures by incubation in fetal bovine (FBS) or human (HS) serum. The compositions of these protein coronas were assessed by nano-LC MS/MS...

AIM: This study aimed to explore the potential of detecting hepatocellular carcinoma (HCC)-associated DNA markers, TP53 249T mutations and aberrant methylation of RASSF1A and GSTP1 genes, for monitoring HCC recurrence. HCC remains a leading cause of death worldwide, with one of the fastest growing incidence rates in the US. While treatment options are available and new ones emerging, there remains a poor prognosis of this disease mostly due to its late diagnosis and high recurrence rate...

BACKGROUND: Complete atrioventricular block in fetuses is known to be mostly associated with autoimmune disease and can be irreversible if no steroids treatment is provided. Conventional methods used in clinical practice for diagnosing fetal arrhythmia are limited since they do not reflect the primary electrophysiological conduction processes that take place in the myocardium. The non-invasive fetal electrocardiogram has the potential to better support fetal arrhythmias diagnosis through the continuous analysis of the beat to beat variation of the fetal heart rate and morphological analysis of the PQRST complex...

Preterm birth is a leading cause of neonatal morbidity and mortality. Although microbial invasion of the amniotic cavity (MIAC) is associated with most early preterm births, the temporal events that occur during MIAC and preterm labor are not known. Group B streptococci (GBS) are β-hemolytic, Gram-positive bacteria, which commonly colonize the vagina but have been recovered from the amniotic fluid in preterm birth cases. To understand temporal events that occur during MIAC, we used a chronically catheterized nonhuman primate model that closely emulates human pregnancy...

In the United States, 1-2.5% of pregnant women are infected with hepatitis C virus (HCV), which carries an approximately 5% risk of transmission from mother to infant. HCV can be transmitted to the infant in utero or during the peripartum period, and infection during pregnancy is associated with increased risk of adverse fetal outcomes, including fetal growth restriction and low birth weight. The purpose of this document is to discuss the current evidence regarding HCV in pregnancy and to provide recommendations on screening, treatment, and management of this disease during pregnancy...

Lucy M Safi, Sarah V Tsiaras
Valvular heart disease in women of childbearing age poses an increased risk of adverse maternal and fetal outcomes, and management in pregnancy can be challenging. Ideally, patients with suspected valvular disease should have preconception counseling by a multidisciplinary team including cardiologists with expertise in pregnancy and a maternal-fetal medicine specialist. Preconception planning should include a cardiac assessment of maternal risk, determination of frequency of surveillance, and a cardiovascular management plan during delivery...

REVIEW
Mark A Clapp, Sarah N Bernstein
All providers who care for reproductive-aged women with cardiac disease should assess these patients' desires and plans for pregnancy at every encounter. For those considering pregnancy, preconception counseling, often performed by a maternal-fetal medicine specialist, can help patients understand the potential implications of pregnancy on their health and estimate the risks of an adverse cardiac event prior to conceiving. There are cardiac conditions, such as pulmonary hypertension and aortic stenosis, in which pregnancy may be contraindicated given the high morbidity and mortality; there are tools available to help quantify a patient's risk...

BACKGROUND: Fetal goitrous hypothyroidism is mainly caused by maternal treatment of Graves' disease. Fetal goiter sometimes compresses the trachea and esophagus and may cause polyhydramnios, preterm labor, complications of labor and delivery, and neonatal respiratory disorder. CASE PRESENTATION: We report a case of fetal goitrous hypothyroidism in which the mother had Graves' disease, which was treated with propylthiouracil. Intra-amniotic levothyroxine (L-T4) administration was performed, and the fetal goiter decreased in size...

One dimensional Doppler Ultrasound (DUS) is a low cost method for fetal auscultation. However, accuracy of any metrics derived from the DUS signals depends on their quality, which relies heavily on operator skills. In low resource settings, where skill levels are sparse, it is important for the device to provide real time signal quality feedback to allow the re-recording of data. Retrospectively, signal quality assessment can help remove low quality recordings when processing large amounts of data. To this end, we proposed a novel template-based method, to assess DUS signal quality...

INTRODUCTION: Treatment of mild to moderate hypertension might not benefit maternal or fetal outcome. This pessimistic point of view may have come about by using non-validated methods for measuring blood pressure in pregnancy combined with inadequate methodology for diagnosis, treatment, and monitoring effects. AIM: To determine the association between AASI in women with type 1 diabetes mellitus (T1DM) and preeclampsia, and to assess the ability of AASI to diagnose preeclampsia...

INTRODUCTION: In France in 2014, there were approximately 1500 patients of reproductive age treated by dialysis. Pregnancy in these patients remains rare, however, the incidence has increased since the 2000s, with a parallel increase in the fetal survival rate. We report 2 cases of pregnancy in short-daily home hemodialysis using low dialysate flow rate. METHODS: Short-daily hemodialysis was continued at the request of the patients. The treatment consisted in an increase of frequency and duration of hemodialysis sessions, an independent blood pressure and dry weight control supervised by nephrological monitoring twice a month and a regular obstetrics follow-up...

Uptake and passage of nanocarriers through the placenta are critical information to develop new therapeutic approaches during pregnancy. In order to assess nanocarriers transplacental passage and penetration into the placenta, we studied and optimized two ex-vivo human models: the dually perfused placenta and the placenta explants. Doubly labelled PEGylated liposomes were used as models to provide data on the penetration and transplacental passage of drugs and liposomes. A HPLC method was set-up to quantify both carboxyfluorescein and lipid-rhodamine...
