Simulation of dB/dt‐Over‐Electric Field Cardiac Magnetostimulation Safety Ratios in 75 Body Models and 18 Gradient Systems

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The IEC 60601‐2‐33 standard provides consensus‐based safety provisions for MRI equipment. Protection of patients against cardiac stimulation (CS) is based on limiting the maximum E‐field induced by MRI gradient coils. In practice, this is achieved by imposing a conservative dB/dt threshold on any gradient waveform.

Heterozygous Beta‐Thalassaemia in Pregnancy: Two Rare Causes of Severe Fetal Anemia Requiring Intrauterine Blood Transfusions

Prenatal Diagnosis, EarlyView.
ABSTRACT Aim In this article, we present two cases of severe fetal hemolytic anemia based on a beta‐thalassaemia trait inherited from a single parent. Results These cases, presented at 20 and 28 weeks' gestation, necessitated intra‐uterine blood transfusions.

Diagnosis and Management of Prenatal Hereditary Pyropoikilocytosis

Prenatal Diagnosis, EarlyView.
ABSTRACT Hereditary pyropoikilocytosis (HPP) is a severe hemolytic anemia caused by variants in SPTA1, SPTB, and EPB41. These weaken horizontal interactions in the erythrocyte cytoskeleton, causing membrane fragmentation and splenic sequestration. It will readily cause fetal anemia and often hydrops fetalis. Prenatal diagnosis requires first ruling out

Hemolytic Disease of the Fetus and Newborn: Fetal RHD Genotyping, Targeted Prophylaxis, and Prenatal Therapies

Prenatal Diagnosis, EarlyView.
ABSTRACT Hemolytic disease of the fetus and newborn (HDFN) remains a significant concern in prenatal care primarily caused by maternal alloimmunization against fetal red blood cell antigens, most commonly the D antigen. Noninvasive fetal RHD genotyping, used as a screening tool, enables targeted antenatal prophylaxis and has been implemented in several

Prenatal Exome Sequencing Analysis in Fetuses With Structural Anomalies: A Multicenter Prospective Cohort Study With Practical Implications

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective To evaluate the diagnostic value of prenatal exome sequencing (ES) integrated with copy number variant (CNV) and single nucleotide variant (SNV) analysis (ES‐CNV/SNV) in fetuses with structural anomalies following negative chromosomal microarray analysis (CMA) and karyotyping, and to delineate the practical challenges encountered ...

The Incremental Yield of CMA Over Karyotype in Fetal Growth Restriction—A Systematic Review and Meta‐Analysis

Prenatal Diagnosis, EarlyView.
ABSTRACT The main objective of our study was to conduct a systematic literature review and a meta‐analysis to evaluate the incremental yield of chromosomal microarray analysis compared with karyotyping in cases of fetal growth restriction. Our review was designed according to the PRISMA guidelines.
