The new coronavirus (Covid 19) has become a hazardous threat due to its prevalence worldwide. Pregnant women are particularly vulnerable to this infectious disease because their immune system is already slightly compromised during pregnancy, making them more susceptible to viral infections. Therefore, the aim of this study was to investigate abortion due to this disease in different countries of the world. Thirty-six articles were analyzed by searching the web of science, Google Scholar, Pubmed databases for the following keywords: Covid 19 and abortion, Covid 19 and fetus, and Covid 19. Thirteen out of the 36 articles were used, and the rest were excluded from the study due to being unrelated to the subject. Articles related to the new coronavirus and abortion were then carefully studied and analyzed. It was shown in various studies that, due to the infection and immune system compromise during pregnancy, the Coronavirus could play a role in abortion and stillbirth. So, a prognosis of this threat could help pregnant women observe the health protocols during the pandemic more seriously so that they are more protected against being infected.
Introduction: With the outbreak of COVID-19, researchers started their studies on the various aspects of the infection by this newly-emerged virus. In addition to the pulmonary infection routes, some signs were discovered regarding psychological and physiological damages. Materials and Methods: Our study aimed at collecting the results of the studies around the world on the possible psychological and physiological damages caused by COVID-19in the neural system. Herein, we gathered 125 related articles up to June 2021 by searching the keywords COVID-19 brain infection, COVID-19 infection disease imaging findings COVID-19, mental health, and COVID-19in the databases such as Scopus, Pubmed, Web of Science, Google Scholar, and Google. The articles unrelated to the objective of our study were excluded, and finally, 43 articles were used. Results: In this study, reports indicate an increase in the volume of gray matter in the hippocampus and olfactory lobe and an increase in anisotropy in the white matter in people with the acute form of the disease compared to people without it. Therefore, psychologically, some forms of mental rumination and apathy were confirmed in affected people. Conclusion: Considering the probable inability of the SARS-COV virus to cross the blood-brain barrier, the reason for the neuropathological lesions and brain encephalopathies has yet to be discerned, and this is a somewhat unknown mechanism
