Researchers compared measurements of dental plaque among current, former, and never smokers using an innovative light-induced fluorescence technology. Objective quantification of dental plaque was necessary to conduct reliable comparisons between smokers and non-smokers.
Ten of the world’s leading experts in diabetes addressed the issue of smoking harm in this vulnerable population in its clinical, medical, behavioral and sociological implications, in order to provide independent consultation and oversight to the development of smoking cessation / harm reduction guidelines for smokers with type 2 diabetes mellitus.
An independent review by the Replica project team examines the impact of tobacco smoke and electronic nicotine delivery systems use on oxidative stress, the precursor of the so-called tobacco related diseases (respiratory and cardiovascular diseases, tumors). To date, the scientific evidence available constitutes a puzzle of information, which, despite experimental and procedural limitations of international studies , already shows a reduced impact of ENDS on oxidative stress compared to cigarette smoking, even if some research have concluded that they do not completely eliminate it, leaving the question still pending
The prestigious American Journal of Respiratory and Critical Care Medicine published a comment by researchers from CoEHAR and the University of Messina regarding a US studies that concluded that “former and current e-cigarette use was associated with higher odds of developing wheezing-related respiratory symptoms”. According to the Italian authors “the significance of the findings needs careful review”.
A recent randomized controlled trial of varenicline (Chantix) combined with psychological support has significantly increased the chance of quitting smoking for 300 smokers with type 2 diabetes mellitus
On 31 May 2022, to celebrate the World No Tobacco Day, CoEHAR, the Center of Excellence for the acceleration of Harm Reduction of the University of Catania, will host the first National Conference on Tobacco Harm Reduction “Risks and benefits of Combustion free products".

CoEHAR researchers investigated for the first time the relationship between biochemically-verified smoking status and SARS-CoV-2 infection in a large population study. The study “The impact of laboratory-verified smoking on SARS-CoV-2 infection: Results from the Troina sero-epidemiological survey”, found that the prevalence of SARS-CoV-2 antibody positivity were reduced in smokers compared to former and never smokers (19.8% vs. 31%)
CoEHAR presented the results of the Replica project during Experimental Biology 2022, the annual meeting that brings together thousands of scientists and experts in the field of anatomy, biochemistry and molecular biology, investigative pathology, pharmacology, and physiology. Representing CoEHAR, the researcher Alfio Distefano, PhD student in neuroscience at the University of Catania
Direct causal relationship between smoking and COVID-19 outcomes: the work of CoEHAR researchers finds confirmations in an english cohort study. Compared with people who had never smoked, current smoking was associated with one-third lower risk of hospitalization
