Accidents & Violence, Author Interviews, JAMA, Johns Hopkins, Pediatrics / 07.04.2020

MedicalResearch.com Interview with: Johnathon P. Ehsani, PhD Assistant Professor Johns Hopkins School of Public Health MedicalResearch.com: What is the background for this study? Response: Car crashes are the leading cause of death and disability for young people. So, what can parents do during the learner stage of licensing to reduce their teenagers’ crash risk during independent driving? The learner stage is a brief window of opportunity to influence the safety of their teenager. This is when teenagers are required to practice driving under the supervision of a licensed adult – typically mom or dad. Once teenagers get their license to start driving on their own, their crash risk increases - but parents have fewer chances to intervene at that point.  (more…)
Author Interviews, Biomarkers, Diabetes, Diabetes Care, Johns Hopkins / 26.03.2020

MedicalResearch.com Interview with: Olive Tang, MD/PhD Student Johns Hopkins School of Medicine   Elizabeth Selvin, PhD, MPH Professor of Epidemiology & Medicine Director, Cardiovascular and Clinical Epidemiology Department of Epidemiology Welch Center for Prevention, Epidemiology and Clinical Research and the Johns Hopkins Bloomberg School of Public Health MedicalResearch.com: What is the background for this study? Response: The best approach to diabetes management in older adults is unclear. A new blood test called high-sensitivity troponin can detect damage to the heart, even in people without any signs or symptoms of heart disease. (more…)
Author Interviews, JAMA, Johns Hopkins, OBGYNE, Race/Ethnic Diversity / 20.07.2019

MedicalResearch.com Interview with: Alison Gemmill, PhD Assistant Professor Johns Hopkins Bloomberg School of Public Health  MedicalResearch.com: What is the background for this study? What are the main findings? Response: A growing body of evidence suggests that the circumstances surrounding the 2016 presidential election may have had a uniquely negative impact on the health of U.S. Latino population. Few studies, however, have evaluated the population health implications of the election for Latina mothers and their children. We used national data and methods that control for temporal patterning to test the hypothesis that preterm birth rose above otherwise expected levels among Latina women in the U.S. following the election of Donald Trump. We find that the number of preterm births among Latina women increased above expected levels following the election. Specifically, we find 3.5 percent more preterm births among Latinas than projected for nine months following election. (more…)
Author Interviews, JAMA, Johns Hopkins, Social Issues / 06.01.2019

MedicalResearch.com Interview with: Megan Wallace, DrPH Department of Epidemiology Johns Hopkins Bloomberg School of Public Health Baltimore, Maryland MedicalResearch.com: What is the background for this study? What are the main findings? Response: Local health departments are often evaluated on a nationwide or statewide basis, however, given diversity among counties that exists even at the state level, we felt there might be a better way to group health departments for evaluation. In this study, we created county-level clusters using local characteristics most associated with the outcomes of interest, which were smoking, motor vehicle crash deaths, and obesity. We then compared county-level percentile rankings for the outcomes within sociodemographic peer clusters vs nationwide rankings. We identified 8 groups of counties with similar local characteristics. Percentile ranks for the outcomes of interest often differed when counties were compared within their peer groups in comparison with a nationwide scale.  (more…)
Author Interviews, Cost of Health Care, Duke, Geriatrics, Hearing Loss, Hospital Readmissions, JAMA / 08.11.2018

MedicalResearch.com Interview with: Nicholas S. Reed, AuD Assistant Professor | Department of Otolaryngology-Head/Neck Surgery Core Faculty | Cochlear Center for Hearing and Public Health Johns Hopkins University School of Medicine Johns Hopkins University Bloomberg School of Public Health MedicalResearch.com: What is the background for this study? Response: This study was a true team effort. It was funded by AARP and AARP Services, INC and the research was a collaboration of representatives from Johns Hopkins University, OptumLabs, University of California – San Francisco, and AARP Services, INC. Given all of the resent research on downstream effects of hearing loss on important health outcomes such as cognitive decline, falls, and dementia, the aim was to explore how persons with hearing loss interacted with the healthcare system in terms of cost and utilization. MedicalResearch.com: What are the main findings? Response: Over a 10 year period, untreated hearing loss (hearing aid users were excluded from this study as they are difficult to capture in the claims database) was associated with higher healthcare spending and utilization. Specifically, over 10 years, persons with untreated hearing loss spent 46.5% more, on average, on healthcare (to the tune of approximately $22000 more) than those without evidence of hearing loss. Furthermore, persons with untreated hearing loss had 44% and 17% higher risk for 30-day readmission and emergency department visit, respectively. Similar relationships were seen across other measures where persons with untreated hearing loss were more likely to be hospitalized and spent longer in the hospital compared to those without evidence of hearing loss.

Author Interviews, MRSA / 05.10.2018

MedicalResearch.com Interview with: Kathryn Dalton, VMD MPH AKC CHF Fellow PhD Student, Davis Lab Environmental Health and Engineering Johns Hopkins Bloomberg School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Animal-assisted interventions (or AAI for short) have become increasing popular in hospitals for the emotional and physical benefits they bring to patients. But there is a risk that these therapy dogs could potential spread infectious germs, including MRSA (methicillin-resistantStaphylococcus aureus), to patients. Our study found that therapy dogs can spread MRSA to patients, and children who had more contact with the therapy dog were at higher risk of getting MRSA. But, we used a new cleaning protocol on the dog with an anti-septic shampoo before the visit and anti-septic wipes during the visit. Patients who had more contact with the dog did not have a higher risk of MRSA when the dog was giving this new cleaning protocol, which made the AAI therapy visits safer for the patients. In addition, the patients’ emotional and physical benefits we observed were not changed by using this dog cleaning protocol.       (more…)
Accidents & Violence, Alcohol, Author Interviews / 03.10.2018

MedicalResearch.com Interview with: Pamela Trangenstein, PhD While  a predoctoral fellow at Johns Hopkins Bloomberg School of Public Health's Center on Alcohol Marketing and Youth (CAMY)  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Research repeatedly shows that alcohol outlet density (the number of businesses that sell alcohol in an area) is associated with violent crime, but studies disagree about whether alcohol outlets that are on premise (e.g., bars, restaurants) or off premise (e.g., liquor stores, beer and wine stores) have a stronger association with violent crime. We used advanced methods that consider both the number of alcohol outlets and their locations to better understand how the association between alcohol outlets and violent crime differs by type of outlet. We found that alcohol outlets that allow off-premise sales like liquor stores had a stronger association with homicide, aggravated assault, and robbery than on-premise outlets like bars and restaurants. We also found that disadvantaged neighborhoods had higher access to the types of alcohol outlets associated with the most harms: off-premise outlets.  (more…)
