Background: Hypercytokinemia, the renin-angiotensin system, hypoxia, immune dysregulation, and vasculopathy with evidence of immune-related damage are implicated in brain morbidity in COVID-19 along with a wide variety of genomic and environmental influences. There is relatively little evidence of direct SARS-CoV-2 brain infection in COVID-19 patients. Methods: Brain histopathology of 36 consecutive autopsies of patients who were RT-PCR positive for SARS-CoV-2 was studied along with findings from contemporary and pre-pandemic historical control groups. Immunostaining for serum and blood cell proteins and for complement components was employed. Microcirculatory wall complement deposition in the COVID-19 cohort was compared to historical control cases. Comparisons …


Nailfold Videocapillaroscopic Alterations As Markers Of Microangiopathy In Covid-19 Patients, Roberta Gualtierotti, Sharon E. Fox, Fernanda Da Silva Lameira, Andrea Giachi, Luca Valenti, Maria Orietta Borghi, Pier Luigi Meroni, Massimo Cugno, Flora Peyvandi May 2023

Nailfold videocapillaroscopic alterations have been described in COVID-19, but their correlations with biomarkers of inflammation, coagulation and endothelial perturbation are still unclear, and no information is available on nailfold histopathology. Nailfold videocapillaroscopy was performed on fifteen patients with COVID-19 in Milan, Italy and the signs of microangiopathy were correlated with plasma biomarkers of inflammation (C reactive protein [CRP], ferritin), coagulation (D-dimer, fibrinogen), endothelial perturbation (Von Willebrand factor [VWF]) and angiogenesis (vascular endothelial growth factor [VEGF]) along with genetic drivers of COVID-19 susceptibility. Histopathological analysis of autoptic nailfold excisions was performed on fifteen patients who died for COVID-19 in New Orleans, …

Gun violence drastically increased in urban cities following the ease of shutdown restric-tions associated with the Coronavirus Pandemic. The association of gun violence and COVID-19 has highlighted the importance of taking a public health perspective, particularly as it relates to impacts on the Black community. In this article we discuss macro-level factors and community traumas in the city of New Orleans, an area that has had longstanding issues related to gun violence. Community structural issues, traumatic stress from disasters, and recommendations to address disparities in social determinants of health are discussed.
