MedicalResearch.com Interview with: [caption id="attachment_26290" align="alignleft" width="150"]Harrison W. Lin, M.D. Assistant Professor Department of Otolaryngology-Head & Neck Surgery UC Irvine Medical Center Orange, CA 92868 Dr. Harrison LIn[/caption] Harrison W. Lin, M.D. Assistant Professor Department of Otolaryngology-Head & Neck Surgery UC Irvine Medical Center Orange, CA 92868 MedicalResearch.com: What is the background for this study? What are the main findings? Response: We reviewed the data from the Integrated Health Interview Series, which is a project funded by the National Institutes of Health to supplement the National Health Interview Survey (NHIS), a household-based, personal interview survey administered by the US Census Bureau and Centers for Disease Control and Prevention since 1957. The NHIS serves as the largest source of health information in the civilian population of the United States. Analyzing the available data on tinnitus symptoms from this survey, we found that approximately 1 in 10 Americans have chronic tinnitus. Moreover, durations of occupational and leisure time noise exposures correlated with rates of tinnitus – people who reported higher rates of loud noise exposures at work and recreationally more frequently reported chronic tinnitus. Finally, health care providers provided advice and treatment plans to patients with chronic tinnitus that were infrequently in line with the clinical practice guidelines published by the American Academy of Otolaryngology-Head & Neck Surgery Foundation.

MedicalResearch.com Interview with: [caption id="attachment_25408" align="alignleft" width="200"]Dr. Álex García-Faura Scientific Director of the Institut Marquès Spain Dr-Álex-García-Faura[/caption] Dr. Álex García-Faura Scientific Director of the Institut Marquès Spain MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our clinical research during the last three years has been focused on the effects of music during the early stages of life; in our preliminary studies, applying music to pregnant patients using abdominal speakers, we discovered that there was no fetal reaction to music and that the fetus would only be able to hear it as a distorted whisper because of the effects of the abdominal wall. We thought that it would be necessary to get the music closer to the fetus, and we decided to try to apply the music vaginally. It was a great decision.

MedicalResearch.com Interview with: Elizabeth A. Masterson, PhD CPH Dr. Masterson is an epidemiologist in the NIOSH Division of Surveillance, Hazard Evaluations and Field Studies CDC MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Masterson: Occupational hearing loss, primarily caused by high noise exposure, is the most common work-related illness in the United States. It is a permanent but entirely preventable condition. Researchers from the National Institute for Occupational Safety and Health (NIOSH), a part of the Centers for Disease Control and Prevention, compared the prevalence of hearing impairment within nine industry sectors and the associated impact on quality of life for noise-exposed workers. Hearing impairment is hearing loss that impacts day-to-day activities. The Mining sector had the highest prevalence of workers with any hearing impairment, and with moderate or worse impairment, followed by the Construction and Manufacturing sectors. Impact on quality of life was measured by calculating disability-adjusted life years (DALYs). DALYs represented the number of healthy years lost because of hearing impairment. This study found that 2.5 healthy years were lost each year for every 1,000 noise-exposed U.S. workers because of hearing impairment. These lost years of good health were shared among the 13% of workers with hearing impairment (about 130 workers out of each 1,000 workers). Mining, Construction and Manufacturing workers lost more healthy years than workers in other industry sectors (3.5, 3.1 and 2.7 healthy years lost, respectively, each year for every 1,000 workers). Mild impairment accounted for 52% of all healthy years lost and moderate impairment accounted for 27%.

University of Southern Denmark. Dr. Hansen[/caption]   Associate Professor Dr. Inger Marie Jensen Hansen, PhD, DMsci Department of Rheumatology Odense university Hospital Svendborg Hospital University of Southern Denmark   MedicalResearch.com: What is the background for this study? Response: Rheumatoid arthritis is a systemic, inflammatory disease that affects 1% of the general population. Apart from main articular manifestations, rheumatoid arthritis may involve other organs including heart, lung, skin, and eye. The auditory system can be affected during the course of the disease as well; however the association between rheumatoid arthritis and hearing impairment has not been clearly defined. It seems that hearing impairment in rheumatoid arthritis is a multifactorial disease affecting by environmental factors and disease and patient characteristics. We did a comprehensive review of all published data to reveal the potential link between rheumatoid arthritis and hearing impairment.

Linkedin: https://www.linkedin.com/in/wilko-grolman-73a4927   MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Grolman: The importance of healthy hearing is extremely important for us humans. Decline in hearing will potentially affect not only our functional status but also our emotional and social health but also our economic status. It is impossible to imagine what the impact of losing one’s hearing ability is while still having a healthy hearing. Although many of us will eventually suffer from reduced hearing as part of the physiological effect of getting older, scientists are alarmed by the fact that hearing loss is on the rise and especially the number of youngsters that are affected is increasing. The WHO in their report of March 2015 reveal some alarming statistics; 360 million people have disabling hearing loss. In the acquired hearing loss group, excessive noise from personal audio devices and concert and festival visits has gained importance. Occupational noise has long been recognized as a source of acquired hearing loss. The WHO recognizes that half of the hearing loss cases can be prevented by primary prevention. For the noise induced hearing loss category, it is important to reduce exposure to loud sounds by raising awareness about the risks, implement relevant legislation and to encourage the use of personal protective devices such as earplugs, noise-canceling earphones and headphones. Our previous systematic review of the effectiveness of wearing earplugs to music venues showed that there were only two studies on this subject of which only one was a randomized clinical trial but had a major different set-up.

Wenqi Gan, MD, PhD Assistant Professor Department of Preventive Medicine and Environmental Health University of Kentucky College of Public Health Lexington, KY 40536MedicalResearch.com Interview with: Wenqi Gan, MD, PhD Assistant Professor Department of Preventive Medicine and Environmental Health University of Kentucky College of Public Health Lexington, KY 40536 Medical Research: What is the background for this study? Dr. Wenqi Gan: In epidemiologic studies on health effects of noise exposure, community noise is typically assessed using noise prediction models, occupational noise is assessed using self-reports or historical records. These methods are able to estimate community noise exposure in residential areas and occupational noise exposure in the workplace; however, these methods are not able to accurately reflect actual personal noise exposure in the home and workplace. The lack of personal noise exposure information is a major limitation of previous studies, which could cause underestimations of the true health effects of noise exposure. Bilateral high-frequency hearing loss, an objective indicator for long-term exposure to loud noise, may be used to investigate health effects of noise exposure. Medical Research: What are the main findings? Dr. Wenqi Gan: This study includes 5223 people aged 20-69 years who participated in the US National Health and Nutrition Examination Survey 1999-2004. Compared with people with normal high-frequency hearing, people with bilateral high-frequency hearing loss were approximately two times more likely to have coronary heart disease. This association was particularly striking for people who were chronically exposed to loud noise in the workplace or leisure time. For example, for currently employed workers with occupational noise exposure history, the possibility of having coronary heart disease increased more than four times. This study confirms that chronic exposure to loud noise is associated with increased risk of coronary heart disease.

MedicalResearch.com Interview with: Isabelle Mosnier, MD, Praticien Hospitalier ORL Otologie, Implants Auditifs et Chirurgie de la Base du Crâne Centre Référent Implant Cochléaire Adulte d'Ile de France Centre Maladies Rares Surdité Génétique de l'adulte et Neurofibromatose de type 2 Groupe Hospitalier de la PITIE-SALPETRIERE Paris MedicalResearch: What is the background for this study? What are the main findings? Dr. Mosnier: Association between hearing impairment and cognitive decline has been established; however, the impact on cognition through cochlear implantation in profoundly deaf elderly patients is not known. The focus was to determine the impact of hearing rehabilitation including cochlear implant on cognitive functions, in addition to the influence of cognitive factors on cochlear implant outcomes over time.
