The high mortality of coronavirus disease 2019 (COVID-19) patients is due to their progression to cytokine-associated organ injuries, primarily the acute respiratory distress syndrome (ARDS). The uncertainties in the molecular mechanisms leading to the switch from the early virus infection to the advanced stage ARDS is a major gridlock in therapeutic development to reduce mortality. Previous studies in our laboratory have identified matrix metalloprotease-3 (MMP3) as an important mediator of bacterial lipopolysaccharide (LPS)-induced ARDS, particularly in the exudative phase. Our studies have also reported elevated plasma MMP3 activity levels in the ARDS patients and that inhibition of MMP3 can reduce the severity of LPS-induced ARDS in mice. Given these observations, targeting MMP3 could be a potential option to treat COVID-19 patients with ARDS, and measurement of MMP3 activity in the plasma may serve as a biomarker for the early detection of ARDS in COVID-19 patients.

How likely is it that a virus or bacteria is causing a patient's symptoms? A new approach to interpret the outcome from multi-pathogen PCR.
Infect Dis (Lond)
January 2025
Department of Epidemiology and Biostatistics, College of Public Health, University of Georgia, Athens, GA, USA.
Background: Whether a detected virus or bacteria is a pathogen that may require treatment, or is merely a commensal 'passenger', remains confusing for many infections. This confusion is likely to increase with the wider use of multi-pathogen PCR.
Objectives: To propose a new statistical procedure to analyse and present data from case-control studies clarifying the probability of causality.
Evaluating convalescent plasma therapy in severe COVID-19: a retrospective cohort study.

December 2024
Department of Pharmacology, School of Medicine, Kashan University of Medical Sciences, Kashan, Iran.
Introduction: Convalescent plasma (CP) therapy is a form of passive immunization which has been used as a treatment for coronavirus disease 2019 (COVID-19). This study aims to evaluate the efficacy and safety of CP therapy in patients with severe COVID-19.
Methodology: In this retrospective cohort study, 50 patients with severe COVID-19 treated with CP at Shahid Beheshti Hospital, Kashan, in 2019 were evaluated.
Epidemiologic threats and outcome of evolving COVID-19-associated mucormycosis from a referral hospital in Egypt.
J Infect Dev Ctries
December 2024
Chest Dpt., Ahmed Maher Teaching Hospital, GOTHI, Cairo, Egypt.
Introduction: The present study aimed to explore the epidemiologic threats and factors associated with the coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM) epidemic that emerged in Egypt during the second COVID-19 wave. The study also aimed to explore the diagnostic features and the role of surgical interventions of CAM on the outcome of the disease in a central referral hospital.
Methodology: The study included 64 CAM patients from a referral hospital for CAM and a similar number of matched controls from COVID-19 patients who did not develop CAM.

Introduction: This study aimed to analyze the levels of MMP-9 and TIMP-1 as biomarkers for identifying lung anatomical and functional abnormalities in coronavirus disease 2019 (COVID-19).
Methodology: Adult COVID-19 patients hospitalized between October and December 2021 were included in the study. MMP-9 and TIMP-1 levels were measured from the blood.
The first reported case of candidemia caused by the novel Candida tropicalis diploid sequence type 1515.

Department of Emergency Medicine, Faculty of Medicine, Universiti Kebangsaan Malaysia, Kuala Lumpur, Malaysia.
Introduction: Since the dawn of the new millennium, Candida species have been increasingly implicated as a cause of both healthcare-associated as well as opportunistic yeast infections, due to the widespread use of indwelling medical devices, total parenteral nutrition, systemic corticosteroids, cytotoxic chemotherapy, and broad-spectrum antibiotics. Candida tropicalis is a pathogenic Candida species associated with considerable morbidity, mortality, and drug resistance issues on a global scale.
Methodology: We report a case of a 43-year-old man who was admitted to our hospital for further management of severe coronavirus disease 2019 (COVID-19) pneumonia.
