Uterine Rescue in High-Risk Gestational Trophoblastic Neoplasia Treated with EMA-CO by Uterine Arteries Embolization due to Arteriovenous Malformations.

Rev Bras Ginecol Obstet 2021 Apr 12;43(4):323-328. Epub 2021 May 12.

Department of Obstetrics, Escola Paulista de Medicina, Universidade Federal de São Paulo, São Paulo, SP, Brazil.

Complete hydatidiform mole (CHM) is a rare type of pregnancy, in which 15 to 20% of the cases may develop into gestational trophoblastic neoplasia (GTN). The diagnostic of GTN must be done as early as possible through weekly surveillance of serum hCG after uterine evacuation. We report the case of 23-year-old primigravida, with CHM but without surveillance of hCG after uterine evacuation. Read More

Excessive Prenatal Supplementation of Iodine and Fetal Goiter: Report of Two Cases Using Three-dimensional Ultrasound and Magnetic Resonance Imaging.

Rev Bras Ginecol Obstet 2021 Apr 12;43(4):317-322. Epub 2021 May 12.

Department of Obstetrics, Escola Paulista de Medicina, Universidade Federal de São Paulo, São Paulo, SP, Brazil.

Fetal thyroid complications in pregnancy are uncommon, and are commonly related to the passage of substances through the placenta. The excessive iodine intake during the pregnancy is a well-known mechanism of fetal thyroid enlargement or goiter, and invasive procedures have been proposed for the treatment of fetal thyroid pathologies. In the present report, we demonstrate two cases from different centers of prenatal diagnosis of fetal thyroid enlargement and/or goiter in three fetuses (one pair of twins, wherein both fetuses were affected, and one singleton pregnancy).

Is there a Role for Antenatal Corticosteroids in Term Infants before Elective Cesarean Section?

Rev Bras Ginecol Obstet 2021 Apr 12;43(4):283-290. Epub 2021 May 12.

Obstetrics & Gynecology Department, Hospital Divino Espírito Santo, Ponta Delgada, Portugal.

Objective:  Cesarean section (CS) delivery, especially without previous labor, is associated with worse neonatal respiratory outcomes. Some studies comparing neonatal outcomes between term infants exposed and not exposed to antenatal corticosteroids (ACS) before elective CS revealed that ACS appears to decrease the risk of respiratory distress syndrome (RDS), transient tachypnea of the neonate (TTN), admission to the neonatal intensive care unit (NICU), and the length of stay in the NICU.

Methods:  The present retrospective cohort study aimed to compare neonatal outcomes in infants born trough term elective CS exposed and not exposed to ACS. Read More

Mapping the peripheral nervous system in the whole mouse via compressed sensing tractography.

J Neural Eng 2021 May 12. Epub 2021 May 12.

Biomedical Engineering, Duke University, 2167 CIEMAS, Duke Box 3382, 101 Science Drive, Durham, North Carolina, 27708, UNITED STATES.

Objective: The peripheral nervous system (PNS) connects the central nervous system (CNS) with the rest of the body to regulate many physiological functions and is therapeutically targeted to treat diseases such as epilepsy, depression, intestinal dysmotility, chronic pain, and more. However, we still lack understanding of PNS innervation in most organs because the large span, diffuse nature, and small terminal nerve bundle fibers have precluded whole-organism, high resolution mapping of the PNS. We sought to produce a comprehensive peripheral nerve atlas for use in future interrogation of neural circuitry and selection of targets for neuromodulation. Read More

Protein quality and quantity influence the effect of dietary fat on weight gain and tissue partitioning via host-microbiota changes.

Cell Rep 2021 May;35(6):109093

Food Biosciences Department, Teagasc Food Research Centre, Moorepark, Fermoy, County Cork P61 C996, Ireland; VistaMilk Research Centre, Teagasc, Moorepark, Fermoy, County Cork P61 C996, Ireland. Electronic address:

We investigated how protein quantity (10%-30%) and quality (casein and whey) interact with dietary fat (20%-55%) to affect metabolic health in adult mice. Although dietary fat was the main driver of body weight gain and individual tissue weight, high (30%) casein intake accentuated and high whey intake reduced the negative metabolic aspects of high fat. Jejunum and liver transcriptomics revealed increased intestinal permeability, low-grade inflammation, altered lipid metabolism, and liver dysfunction in casein-fed but not whey-fed animals.
