Protecting lungs from ventilator-induced injury
An unfortunate truth about using mechanical ventilation to save lives is that the pressure can cause further lung damage. Scientists have identified a helpful molecule produced by immune cells during ventilation and are working to boost that natural process to find a therapy that could lower the chances for lung damage in patients on vents.
High-risk periodontal pathogens contribute to the pathogenesis of atherosclerosis
Microorganisms cause periodontal disease (PD). These microbes can enter the general circulation causing bacteremia. The result can be adverse systemic effects, which could promote conditions such as cardiovascular disease. Level A evidence supports that PD is independently associated with arterial disease. PD is a common chronic condition affecting the majority of Americans 30 years of age and older.
