This study will be a descriptive comparison of the effects of live attenuated influenza virus (FluMist) on nasal inflammation and oxidative stress in healthy young adults who are not exposed to smoke vs smokers. It is hypothesized that passive exposure to second-hand smoke (SHS) results in increased susceptibility to the effects of influenza virus in nasal epithelium in humans and that these effects are mediated by SHS-induced oxidative stress
Epidemiologic evidence supports a significant relationship between passive cigarette smoke exposure and increased risk for viral respiratory illnesses. Published and preliminary data suggest that airborne pollutants including tobacco smoke increase susceptibility of respiratory epithelium to infection with influenza A and that this effect is at least partially mediated by oxidative stress. However, no studies have specifically looked at the interaction between smoking and the effects of influenza virus in human volunteers.

Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.
Governmental guidelines and objectives pertaining to public food supply and nutrition including recommendations for healthy diet and changes in food habits to ensure healthy diet.
Surgical reinnervation of a denervated peripheral target using a healthy donor nerve and/or its proximal stump. The direct connection is usually made to a healthy postlesional distal portion of a non-functioning nerve or implanted directly into denervated muscle or insensitive skin. Nerve sprouts will grow from the transferred nerve into the denervated elements and establish contact between them and the neurons that formerly controlled another area.
Process of evaluating the health of a patient and determining if they are healthy enough for surgery.
