Studies 9• Project Title: EPIDEMIOLOGY OF AGE RELATED HEARING LOSSPrincipal Investigator & Institution: Cruickshanks, Karen J.; Professor; Ophthalmologyand Visual Sci; University of Wisconsin Madison 750 University Ave Madison, Wi 53706Timing: Fiscal Year 2002; Project Start 01-MAR-1993; Project End 28-FEB-2003Summary: The purpose of this application is to re-examine a large population- basedcohort to determine the 5-year incidence and progression of hearing loss and the riskfactors for each outcome. Participants (n=3753) in Beaver Dam, WI, were ages 48-92years at baseline. The re- examinations will be conducted, using the same standardizedprotocols for otoscopy, screen tympanometry, pure tone audiometry, word recognitiontests and distortion product otacoustic emissions. A standardized questionnaire aboutmedical history, noise exposure, and the functional impact of hearing impairment willbe administered. New protocols will build upon cross-sectional results which suggestedthat atherosclerosis, exposure to tobacco smoke and familial factors may be associatedwith hearing loss. B-mode carotid ultrasound will be used to obtain an objective markerof generalized atherosclerosis. Serum cotinine, an objective measure of exposure totobacco smoke will be measured. Using extensive pedigree and genetic markerinformation obtained in the Beaver Dam Linkage Studies of Age-Related OcularDisorders, segregation analyses and preliminary linkage studies will be performed toelucidate genetic factors for hearing loss. The prevalence of olfactory deficits will bemeasured using an odor identification test. Data on vision, ocular disorders andphysical functioning will be available from the planned ten-year follow-up of the BeaverDam Eye Study. A 7-year follow-up telephone interview will be used to assessprospective relations between multiple sensory deficits and function. The study isintended to provide new data about the risks of incidence and progression of hearingloss in older adults and potentially modifiable factors associated with incidence andprogress of hearing loss. It will provided much-needed, population-based data on theprevalence and risk factors for olfactory deficits.Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen• Project Title: LONG TERM SEQUELAE OF OTITIS MEDIAPrincipal Investigator & Institution: Hunter, Lisa L.; University of Minnesota TwinCities 200 Oak Street Se Minneapolis, Mn 554552070Timing: Fiscal Year 2002Summary: This abstract is not available.Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen• Project Title: MAPPING AUDITORY BRAIN FUNCTION WITH MN-ENHANCEDMRIPrincipal Investigator & Institution: Turnbull, Daniel H.; Associate Professor ofRadiology and Pat; Radiology; New York University School of Medicine 550 1St AveNew York, Ny 10016Timing: Fiscal Year 2004; Project Start 01-JUL-2004; Project End 30-JUN-2006Summary: (provided by applicant): Functional neuroimaging methods for mappingneural activity in the mouse brain are required to analyze altered brain function ingenetically-engineered mice with defined neuroanatomical and/or neurological defects.In larger rodents and primates, including humans, functional magnetic resonanceimaging (fMRI) has been used increasingly to map brain activity in the major sensorysystems. However, effective fMRI approaches have been difficult to implement in mice
