Nanoplastics causes extensive congenital malformations during embryonic development by passively targeting neural crest cells. ENVIRONMENT INTERNATIONAL 2023; 173:107865.

Abstract
Nanomaterials are widespread in the human environment as pollutants, and are being actively developed for use in human medicine. We have investigated how the size and dose of polystyrene nanoparticles affects malformations in chicken embryos, and have characterized the mechanisms by which they interfere with normal development. We find that nanoplastics can cross the embryonic gut wall. When injected into the vitelline vein, nanoplastics become distributed in the circulation to multiple organs. We find that the exposure of embryos to polystyrene nanoparticles produces malformations that are far more serious and extensive than has been previously reported. These malformations include major congenital heart defects that impair cardiac function. We show that the mechanism of toxicity is the selective binding of polystyrene nanoplastics nanoparticles to neural crest cells, leading to the death and impaired migration of those cells. Consistent with our new model, most of the malformations seen in this study are in organs that depend for their normal development on neural crest cells. These results are a matter of concern given the large and growing burden of nanoplastics in the environment. Our findings suggest that nanoplastics may pose a health risk to the developing embryo.

A Rare Case Report of Thoracic Ectopia Cordis: An Obstetrician's Point of View in Multidisciplinary Approach. Case Rep Pediatr 2016; 2016:5097059. [PMID: 27957373 PMCID: PMC5120199 DOI: 10.1155/2016/5097059] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2016] [Accepted: 10/05/2016] [Indexed: 11/18/2022] Open
Abstract
Ectopia cordis is a rare congenital anomaly associated with the heart positioned outside of the thoracic cavity either partially or completely. It can be associated with other congenital abnormalities. Overall, the prognosis for infants with ectopia cordis is very poor but depends greatly on the type and severity of ectopia cordis and intracardiac and associated malformations. We present one case of a fetus with prenatally diagnosed thoracic ectopia cordis with intracardiac defects and omphalocele, all the abnormalities seen in pentalogy of Cantrell except a diaphragmatic defect. Considering poor prognosis for fetus, conservative management of prenatal care has been chosen. At the 42nd gestational week, during the active stage of labor, due to fetal distress, cesarean section was performed at a tertiary level hospital. The condition of the infant was impairing rapidly and the newborn succumbed within 24 hours. We discuss the perinatal care concerning this rare anomaly.
