ABSTRACT
Background and objectives: SARS-C0V-2 infections have varied manifestations among individuals ranging from asymptomatic or mild symptoms to severe disease and death. This study is done to look into various histopathological changes in lung, liver, and kidney tissues among Covid19 positive autopsies with cellular tropism and viral load among various organs by immunohistochemistry (IHC) for the SARS-C0V-2 viral marker. Method(s): A prospective descriptive study of core biopsies from covid19 positive autopsies from the lung, liver, and kidneys were taken from 20 cases. A routine histopathological examination of the tissues with IHC staining for SARS-CoV-2 cocktail antibodies was performed and assessed. Result(s): Histopathological changes in the lung, liver, and kidney tissues showed changes of varying severity. On IHC, in the lung, the tropism for SARS-CoV-2 was seen in pneumocytes, bronchial epithelial cells, endothelial cells, and macrophages. In the kidney, tropism was seen towards tubular epithelial cells and endothelial cells. In the liver, hepatocytes and bile duct epithelial cells were positive. Variable viral density was seen in different organs which varied from case to case. The density of the viral load was highest in the lung and lower in the kidney and least in the liver. Conclusion(s): In this study the various histopathological changes and cellular tropism of the SARS-CoV-2 among Lung, liver, and kidney tissues have been described and compared with various similar studies across the globe.Copyright © 2023 International Journal of Life Sciences Biotechnology and Pharma Research.

ABSTRACT
OBJECTIVES: Approximately 1% of individuals have a hereditary cancer predisposition syndrome, however, the majority are not aware. Collecting a cancer family history (CFH) can triage patients to receive genetic testing. To rigorously assess different methods of CFH collection, we compared a web-based tool (WBT) to usual care (clinician collects CFH) in a randomized controlled trial. METHODS: New gynecologic oncology patients (seen 9/2019-9/2021) were randomized to one of three arms in a 2:2:1 allocation ratio: 1) usual care clinician CFH collection, 2) WBT completed at home, or 3) WBT completed in office. The WBT generated a cancer-focused pedigree and scores on eight validated cancer risk models. The primary outcome was collection of an adequate CFH (based on established guidelines) with usual care versus the WBT. RESULTS: We enrolled 250 participants (usual care - 110; WBT home - 105; WBT office - 35 [closed early due to COVID-19]). Within WBT arms, 109 (78%) participants completed the tool, with higher completion for office versus home (33 [94%] vs. 76 [72%], P = 0.008). Among participants completing the WBT, 63 (58%) had an adequate CFH versus 5 (5%) for usual care (P < 0.001). Participants completing the WBT were significantly more likely to complete genetic counseling (34 [31%] vs. 15 [14%], P = 0.002) and genetic testing (20 [18%] vs. 9 [8%], P = 0.029). Participant and provider WBT experience was favorable. CONCLUSIONS: WBTs for CFH collection are a promising application of health information technology, resulting in more comprehensive CFH and a significantly greater percentage of participants completing genetic counseling and testing.
