Over 182 million confirmed cases of COVID-19 and more than 4 million deaths have been reported to date around the world. It is essential to identify broad-spectrum antiviral agents that may prevent or treat infections by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) but also by other coronaviruses that may jump the species barrier in the future. We evaluated the antiviral selectivity of griffithsin and sulfated and non-sulfated polysaccharides against SARS-CoV-1 and SARS-CoV-2 using a cytotoxicity assay and a cell-based pseudoviral model. The half-maximal cytotoxic concentration (CC50) and half-maximal effective concentration (EC50) were determined for each compound, using a dose-response-inhibition …

An Investigation Into The Response Of The Us And Eu5 To The Covid-19 Disease (Convergence Of Two Pandemics: Covid-19 And Ncds), Omar Hassan

Publications and Research

In late December 2019, a coronavirus disease (COVID-19) was identified in Wuhan China. COVID-19 was a result of the novel severe acute respiratory syndrome coronavirus 2 (SARA-CoV-2), which has resulted in a worldwide sudden and substantial increase in hospitalizations for pneumonia with multiorgan disease. As of October 6, 2020, SARS-CoV-2 has affected more than 200 countries, resulting in more than 35 million identified cases with more than 1 million confirmed deaths.

This is a cross-sectional, non-interventional, observational study in patients infected with the novel coronavirus (SARS-CoV-2) or Covid-19, using John Hopkins University database JHU Coronavirus map. The data collected from …

A Real-World Analysis Of Patient Characteristics And Predictors Of Hospitalization Among Us Medicare Beneficiaries With Respiratory Syncytial Virus Infection, Veronique Wyffels, Furaha Kariburyo, Sandra Gavart, Roman Fleischhackl, Huseyin Yuce

Publications and Research

Introduction: Little has been published on respiratory syncytial virus (RSV) among Medicare patients at high risk (HR) of RSV complications due to age or comorbidity. Methods: Adult patients (at least 18 years of age) with at least 1 diagnostic code for RSV were identified using the 5% US Medicare database from 2011 through 2015. Patients were required to have continuous health plan enrollment for 180 days pre- and 180 days post-RSV diagnosis (baseline and follow-up periods, respectively). HR was defined as diagnosis of chronic lung disease, congestive heart failure, or weakened immune system for 180 days during the base-line period. …

Common Cell Shape Evolution Of Two Nasopharyngeal Pathogens, Frédéric J. Veyrier, Nicolas Biais, Pablo Morales, Nouria Belkacem, Cyril Guilhen, Sylvia Ranjeva, Odile Sismeiro, Gérard Péhau-Arnaudet, Eduardo P. Rocha, Catherine Werts, Muhamed-Kheir Taha, Ivo G. Boneca

Respiratory infectious diseases are the third cause of worldwide death. The nasopharynx is the portal of entry and the ecological niche of many microorganisms, of which some are pathogenic to humans, such as Neisseria meningitidis and Moraxella catarrhalis. These microbes possess several surface structures that interact with the actors of the innate immune system. In our attempt to understand the past evolution of these bacteria and their adaption to the nasopharynx, we first studied differences in cell wall structure, one of the strongest immune-modulators. We were able to show that a modification of peptidoglycan (PG) composition (increased proportion of pentapeptides) …

Trends In Mortality From Septicaemia And Pneumonia With Economic Development: An Age-Period-Cohort Analysis, Irene O.L. Wong, Benjamin J. Cowling, Gabriel M. Leung, Mary Schooling

Publications and Research

Background
Hong Kong population has experienced drastic changes in its economic development in the 1940s. Taking advantage of Hong Kong’s unique demographic and socioeconomic history, characterized by massive, punctuated migration waves from Southern China, and recent, rapid transition from a pre-industrialized society to the first ethnic Chinese community reaching ‘‘first world’’ status over the last 60 years (i.e., in two or three generations), we examined the longitudinal trends in infection related mortality including septicemia compared to trends in non-bacterial pneumonia to generate hypotheses for further testing in other recently transitioned economies and to provide generalized aetiological insights on how economic …

How Does Socioeconomic Development Affect Copd Mortality? An Age-Period-Cohort Analysis From A Recently Transitioned Population In China, Jing Chen, Mary Schooling, Janice Mary Johnston, Anthony Johnson Hedley, Sarah Morag Mcghee

Publications and Research

Background
Chronic obstructive pulmonary disease (COPD) is a leading cause of death, particularly in developing countries. Little is known about the effects of economic development on COPD mortality, although economic development may potentially have positive and negative influences over the life course on COPD. We took advantage of a unique population whose rapid and recent economic development is marked by changes at clearly delineated and identifiable time points, and where few women smoke, to examine the effect of macro-level events on COPD mortality.

Methods
We used Poisson regression to decompose sex-specific COPD mortality rates in Hong Kong from 1981 to …

Alcohol And Cardio-Respiratory Deaths In Chinese: A Population-Based Case-Control Study Of 32,462 Older Hong Kong, Mary Schooling, Tai Hing Lam, Sai Yin Ho, Yao He, Kwok Hang Mak, Gabriel M. Leung

Publications and Research

Background
In observational studies moderate alcohol use reduces cardio-respiratory mortality. However observational studies may be biased by many factors including residual confounding by unmeasured differences between moderate alcohol users and other groups or by changes in alcohol use with ill-health and aging. We used two different analytic strategies in an under-studied population, i.e. southern Chinese, to provide an assessment of the specific impact of moderate alcohol use on mortality from ischemic heart disease (IHD) and chronic obstructive pulmonary diseases (COPD).

Methods
In a population-based case-control study of all adult deaths in Hong Kong Chinese in 1998, we used adjusted logistic …
