Article Abstract
We report, for the first time, the surprising presence of toxic nanoparticles, especially silver, in the brain of a fetus, who died unexpectedly at the end of a regular pregnancy. After an accurate autopsy, including the examination of the fetal annexes, an in-depth anatomopathological study of the nervous system and a search by scanning electron microscopy of nanoparticles in the brain, we highlighted the sequence of events that may have led to this fetal death, triggered primarily by the transition of nanosized xenobiotics from the mother to the fetal bloodstream. From this report emerges the importance of considering the search of nanosubstances in the brain during routine investigations following unexpected and unexplained fetal and infant deaths.

Background: Adaptative desaturation in fatty acid (FA) is an emerging hallmark of cancer metabolic plasticity. Desaturases such as stearoyl-CoA desaturase (SCD) and fatty acid desaturase 2 (FADS2) have been implicated in multiple cancers, and their dominant and compensatory effects have recently been highlighted. However, how tumors initiate and sustain their self-sufficient FA desaturation to maintain phenotypic transition remains elusive.
Objective: This study aimed to explore the effectiveness of combining fetal heart sequential cross-sectional scanning with drawing methods, mind mapping, and case-based learning (CBL) for training in fetal conotruncal anomalies (CA) screening.
Method: An experimental control method was employed. Doctors participating in continuing fetal ultrasound education were randomly divided into two groups.
Introduction: There exists a prevailing concern regarding the heightened susceptibility of women with a solitary kidney to unfavorable consequences during pregnancy. Irrespective of the underlying etiology, individuals with a solitary kidney are advised to have regular annual screenings for blood pressure and urinalysis due to their increased susceptibility to developing proteinuria, hypertension, and renal failure.
Objective: To investigate the risk of adverse pregnancy outcomes in women with a maternal solitary kidney by comparing maternal and fetal outcomes to those of healthy pregnant women.
Neuroblastoma is a rare tumour originating from neural crest cells, primarily occurring in the adrenal glands and sympathetic ganglia, with prenatal diagnosis often complicated by the difficulty in distinguishing it from other foetal abdominal or paraspinal masses. We present a case of foetal neuroblastoma in a 26-year old woman who, at 36 weeks of gestation, experienced absent foetal movements, leading to ultrasound confirmation of foetal demise with associated effusions. An emergency caesarean section revealed a stillborn male foetus with a previously undetected encapsulated mass in the posterior mediastinum, which was confirmed as neuroblastoma through histopathological analysis.
