RESUMO
The Severe acute respiratory syndrome and the Middle East respiratory syndromes emerged in 2002 and 2012 respectively. Currently the world is witnessing a global pandemic caused by a novel coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS CoV- 2) causing the Coronavirus 2019 (COVID-19). Mucormycosis is a fungal infection primarily affecting individuals with an immunocompromised state like diabetes mellitus, malignancies etc. Patients who have or have had COVID-19 infection with pre-existing uncontrolled Type 2 Diabetes mellitus are presumably more vulnerable for emergence of fungal infections cases. This article presents a report of 6 cases with histopathological proven mucormycosis associated with COVID-19 and uncontrolled Diabetes mellitus.
RESUMO
In recent years, hundreds of candidate protein biomarkers have been identified using discovery-based proteomics. Despite the large number of candidate biomarkers, few proteins advance to clinical validation. We propose a hypothesis-driven approach to identify candidate biomarkers, previously characterized in the literature, with the highest probability of clinical applicability. A ranking method, called the "hypothesis-directed biomarker ranking" (HDBR) system, was developed to score candidate biomarkers based on seven criteria deemed important in the selection of clinically useful biomarkers. To demonstrate its application, we applied the HDBR system to identify candidate biomarkers for the development of a diagnostic test for the early detection of colorectal cancer. One-hundred and fifty-one candidate biomarkers were identified from the literature and ranked based on the specified criteria. The top-ranked candidates represent a group of biomarkers whose further study and validation would be justified in order to expedite the development of biomarkers that could be used in a clinical setting.
