Purpose: To measure fetal renal volume in normoglycemic and hyperglycemic pregnancies.
Methods: A longitudinal prospective study was conducted and included 92 hyperglycemic and 339 normoglycemic pregnant women attended at the prenatal service of a hospital from Rio de Janeiro State. Ultrasound examinations were performed to estimate gestational age at baseline and the kidney volume was estimated using the prolate ellipsoid volume equation.
Results: Fetal kidney volume growth between normoglycemic and hyperglycemic pregnancies are significantly different. The fetal kidney volume growth in pregnancy is positively correlated with gestational age explained by these predictor equations, by group: normal renal volume = exp (6.186 + 0.09 × gestational week); hyperglycemic renal volume = exp (6.978 + 0.071 × gestational week) and an excessive growth pattern for hyperglycemic pregnancies may be established according to gestational age.
Conclusion: This is important for early detection of abnormalities in pregnancy, particularly in diabetic mothers.

The global issue of aging populations has become increasingly prominent, thus the research and development for anti-aging therapies to assure longevity as well as to ameliorate age-related complications is put high on the agenda. The young humoral milieu has been substantiated to impart youthful characteristics to aged cells or organs. Extracellular vesicles (EVs) are a heterogeneous group of cell-derived membrane-limited structures that serve as couriers of proteins and genetic material to regulate intercellular communication.

Background: Organ procurement from brain-dead pregnant women is rare and typically occurs postfetal delivery. In this case report, we describe organ procurement from a brain-dead woman in her third trimester of pregnancy with a nonviable fetus remaining in utero.
Case Summary: We report a 33-year-old woman at 38 weeks gestation who suffered anoxic brain injury following cardiac arrest due to suspected opioid overdose.
ALG8-CDG: Advances in Molecular and Prenatal Phenotyping Facilitate Prenatal Diagnosis and Genetic Counseling.

Medical Genetic Center, Guangdong Women and Children Hospital, Guangzhou, Guangdong, 510010, China.
Background: ALG8-congenital disorder of glycosylation (ALG8-CDG) is a rare inherited metabolic disorder leading to severe multisystem manifestations, with no reported prenatal patients to date.
Methods: We describe two fetuses from a single family with ALG8-CDG presenting with prenatal hydrops, undergoing comprehensive prenatal ultrasound, umbilical cord blood biochemistry, autopsy, placental pathology, and genetic testing.
Results: Prenatal ultrasound revealed fetal hydrops, skeletal anomalies, cardiac developmental abnormalities, cataracts, echogenic kidneys and bowel, oligohydramnios, choroid plexus cysts, and intrauterine growth restriction.

Retroperitoneal teratomas are rare neoplasms in neonates, presenting with nonspecific symptoms and variable clinical features, making diagnosis challenging. Radiological investigations, particularly fetal ultrasound and contrast-enhanced computed tomography, play a critical role in their detection. Differential diagnoses include neuroblastoma, adrenal hemorrhage, and congenital cystic lesions, which share overlapping clinical and imaging features.

A male fetus at 20 weeks of gestation presented with severe bilateral hydroureteronephrosis and distended bladder due to a large ureterocele. A percutaneous ureterocele puncture at 21+3 weeks aimed to decompress the ureterocele, unclog the lower urinary tract, and prevent renal damage. Post-puncture, the ureterocele decompressed, with improved left hydronephrosis and a normal right kidney.
