Infective Endocarditis as a complication of COVID-19 infection; A case report and review of literature

COVID-19 has been known to induce systemic inflammation and hyper coagulate state leading to different complications. Cardiovascular complications are one of the most important among complications following COVID-19 infection. A 57 years old woman with past medical history of COVID-19 infection about two months ago came to our hospital with presentation of fever and dyspnea. During workup, tricuspid valve infection associated with pulmonary septic emboli was diagnosed without any obvious risk factor for infective endocarditis. It seems that COVID-19 infection may increase the rate of endocarditis in patients with or without risk factors of endocarditis.

Local electric field factors by a combined charge-transfer and point–dipole interaction model

A model for the local electric field as a linear response to a frequency-dependent external electric field is presented based on a combined charge-transfer and point–dipole interaction force-field model.
