Response: As nasal and oral cavities are major points of entry and transmission for human coronaviruses our team of physicians and scientists (Craig Meyers, Janice Milici, Samina Alam, David Quillen, David Goldenberg and Rena Kass of Penn State College of Medicine and Richard Robison of Brigham Young University) were interested in testing common over-the-counter oral antiseptics and mouthwashes for their efficacy to inactivate infectious human coronavirus, which is structurally similar to SARS-CoV-2, the virus that causes COVID-19. While we wait for a vaccine for COVID-19 to be developed, methods to reduce transmission are needed. We chose products that are readily available and often already part of people’s daily routines.

DeBakey Veterans Affairs Medical Center Section of Cardiology, Department of Medicine Baylor College of Medicine Houston    MedicalResearch.com: What is the background for this study? Response: E-cigarettes typically cost more than combustible cigarettes and there is more variability in cost due to a wide variety of flavors, e-cigarette liquid, and vaping device that are available in the market. Therefore, use of e-cigarettes may vary depending on income with potentially higher use among higher income individuals.

Director of the Center for Tubulointerstitial Kidney Disease Stanford University Dr. Anand[/caption] Shuchi Anand M.D. M.S. Director of the Center for Tubulointerstitial Kidney Disease Stanford University MedicalResearch.com: What is the background for this study? Response: Seroprevalence (or presence of antibodies in response to SARS CoV-2) is considered by many experts to be the most complete to track the spread of COVID19 in communities. However seroprevalence studies are hard to conduct, because they require going into communities and underdoing random blood draws. Many people—especially racial and ethnic minorities, or people with underlying health conditions, or people with language barriers—may be hard to reach for these types of surveys. Plus outreach into communities is very difficult in light of the COVID19 pandemic. To mitigate this problem we worked with a random sample of 28,503 patients on hemodialysis, the vast majority of whom are covered by Medicare. They get their blood drawn monthly, as part of their routine care. Furthermore even though we used a random sample, we know that patients on dialysis are more likely to be racial and ethnic minorities, and more likely to come from disadvantaged backgrounds.

MedicalResearch.com Interview with: corona virus-Covid19Dr. Francesco Venturelli Servizio di Epidemiologia Direzione Sanitaria - Azienda USL-IRCCS di Reggio Emilia Padiglione Ziccardi, Via Amendola MedicalResearch.com: What is the background for this study? Response: Contact tracing and isolation for people testing positive for SARS-CoV-2 are two of the main strategies to limit the viral spread and contain the current pandemic. Long persistence of viral RNA detected by RT-PCR on nasopharyngeal swabs is commonly reported, while its correlation to virus viability is still debated. MedicalResearch.com: What are the main findings?  Response: The study showed that in people with COVID-19, the median time between symptoms onset and viral clearance at RT-PCR was 36 days. Moreover, an overall 20% risk of “false negative” results at RT-PCR was observed, decreasing with time from diagnosis.

Response: News media and politicians frequently discuss the high toll of deaths from firearms and drug overdoses. They usually mention the numbers of deaths, citing figures like 40,000 firearm deaths last year, or death rates such as 20 overdose deaths per 100,000 population. But for most people, it's hard to grasp the real meaning of both the large absolute numbers and the small annual rates.  So in a new study published in the American Journal of Medicine, I used official death certificate data to calculate the chance that an American child will die from a gunshot or a drug overdose over the course of a lifetime.

Response: With the resurgence of COVID-19 and the likely seasonal resurgences, we were interested in whether those in low-income areas would be able to get access to the hospital care they might need. So we examined the distribution of ICU beds across the country and also looked at differences in the availability of ICU beds by household income in the community.

Response: People with diabetes are known to have an increased risk of undergoing amputation procedures, however it was not known if patients with gout have an elevated independent risk for digit or limb amputations, or whether gout potentiates amputation rates in patients with diabetes. This analysis assessed and compared the rate of amputation procedures conducted in patients with gout, diabetes, both gout and diabetes, and neither gout nor diabetes via examining records from a large US claims database.

What are the main findings? Response: The infection fatality ratio (IFR) of Covid19 infections is a key parameter to model the future burden of this pandemic. Case fatality rates at any point in time provide a biased estimate of IFR because of the undercounting in both the reported number of covid deaths (numerator) and the reported number of Covid19 cases (denominator). Instead, this study looked at the temporality or time trend of the CFRs within specific counties in the US (where data were deemed to be mature) to understand the underlying IFRs that these trends allude to. It estimates county-specific IFR to range from 0.5% to 3.6%, with a population average for the US at 1.3% (95% CCI: 0.6% - 2.1%).

Chew, M.D.Director of the Division of Epidemiology and Clinical ApplicationsDeputy Clinical Director at the National Eye Institute (NEI), National Institutes of Health Dr. Chew[/caption] Emily Y. Chew, M.D. Director of the Division of Epidemiology and Clinical Applications Deputy Clinical Director at the National Eye Institute (NEI), National Institutes of Health  MedicalResearch.com: What is the background for this study? Response: Dementia is a common disorder that was estimated to have a worldwide prevalence of 44 million in 2016 and is projected to hit 115 million by 2050. Many phase 3 trials of various therapies have failed and we have no treatment currently available for the prevention or reduction of the course of dementia. A slow neurocognitive decline throughout life is part of the normal process of aging. However, there is a subset of individuals who may have accelerated aging and is at high risk of development dementia. If the course of such accelerated decline could be altered in any way, it would be important to evaluate. The role of diet with biologic aging has been studied and diet has been also found to be associated with age-related conditions linked to dementia, including cardiovascular disease and diabetes. We were interested in the cognitive function of our participants who had another neurodegenerative disease, age-related macular degeneration (AMD). We had conducted two randomized controlled clinical trials designed to evaluate the role of oral supplements for the treatment of AMD. We also studied cognitive function in both clinical trials of nearly 8,000 participants who were followed for 10 years. We also evaluated the dietary habits of the participants with food frequency questionnaires (FFQ) at baseline. Cognitive function testing was conducted in the first study, the Age-Related Eye Disease Study (AREDS) near the end of the clinical trial while the AREDS2, the second study, evaluated cognitive function testing at baseline and every 2 years until year 6. AREDS study evaluated cognitive function with in-clinic study visits while AREDS2 was conducted using telephone interviews. Our aim was to determine whether closer adherence to the alternative Mediterranean diet (aMED) was associated with impaired cognitive function these two studies. We were interested in the particular components of the Mediterranean diet that may be important. We also evaluated the interaction of genetics with the diet.

Response: While COVID-19 has disrupted nearly every aspect of healthcare, whether its virtual appointments or delayed surgeries; there are certain things that are inevitable – like childbirth. As this virus continues to take over the country and we learn more about it each day, pregnant women are facing new challenges and fears. For women approaching their due dates, questions about staying healthy, keeping their baby safe and limiting their risk of exposure while in the hospital are all leading to anxiety and stress. And while policies and guidelines are constantly changing, as physicians we need to remind our patients that we are there to alleviate their concerns, address their questions and remind them to not lose sight of the joy the comes with bringing a child into the world. It’s a scary time for everyone, but by working together and supporting one another, we will get through this.

Would you briefly explain what is meant by a convolutional neural network? Response: When a very young child looks at a picture, she can easily identify cats and dogs, however, even the most advanced computers had struggled at this task until recently. Computers began to “see” with the recent advancement of Deep Learning techniques. Deep Learning is a machine learning technique that teaches computers to learn from raw data. Most deep learning methods use artificial neural network architectures, imitating human brain, and convolutional neural networks (CNN) is a particular type of deep learning architecture, imitating the visual cortex. CNN is especially powerful for recognizing images. CNN exploit the information contained in image datasets to automatically learn features and patterns.

Response: Executive physicals are 1 to 2-day comprehensive health assessments offering disease screening and preventive testing. Large companies can arrange for these evaluations for senior executives. They are often offered by prestigious academic medical centers, but can also be located in less formal settings like spas. They generally include a set of tests that sometimes vary based on patient characteristics. Any tests that are done in response to from findings from executive physicals are billed to health insurance companies. A single 2008 paper described executive physicals and criticized them for being non-evidence based. Since then, executive physicals have grown in popularity, but their nature and impact have not been described. We set out to describe included services and cost of executive physicals at top academic medical centers.

Response: Unfortunately,  most systematic reviews exclude non-English trials, mostly for convenience, but nearly all systematic reviews wind up excluding at least 1 non-English trial.  We looked at whether this was justified, since Google Translate is a free and easily usable platform.  We had native-language speakers in 9 languages (Chinese, French, German, Italian, Japanese, Korean, Romanian, Russian and Spanish) abstract data and had another researcher abstract all the articles using Google Translate. We found that there was over 90% agreement and that the few differences were due to human error, not to problems with the translations.

Response: Intimate partner violence, often known as domestic violence, can have devastating consequences to one’s health and wellbeing. It can lead to mental illness, substance abuse, unintended pregnancy, and even death. This is a serious public health issue in America: one in three men—and even more women—experience it in their lifetimes. Because this is such an important topic, and the last time we made a recommendation on it was in 2013, the U.S. Preventive Services Task Force reviewed the most recent evidence to determine how clinicians can help prevent the negative health effects of intimate partner violence.

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.

MedicalResearch.com Interview with: SMARTPHONE, M.D. A NEW APP TO DIAGNOSE URINARY TRACT INFECTIONS Michael J. Mahan PhD Professor, Microbiology and Molecular Genetics Dept of Molecular, Cellular, and Developmental Biology University of California, Santa Barbara, CA MedicalResearch.com: What is the background for this study? What are the main findings? Response: Urinary tract infections (UTIs) cause nearly 10 million doctor visits each year in the United States. Women are much more likely to have a UTI than men, and are particularly harmful to pregnant women and can cause miscarriage. Thus, there is a medical need for rapid, low-cost, on-site testing — particularly in resource-limited settings. We developed a new app that enables a smartphone to identify (ID) bacteria causing UTIs in just one hour — a fraction of the time and cost of clinical diagnostics.

What are the main findings? Response: Breastfeeding is a time-intensive and culturally and emotionally charged topic in the U.S. with many different stakeholders. Women hear the strong message that they should breastfeed their infants for the first year of life, yet it is unambiguously clear that they find these guidelines hard to follow in practice. We were interested in exploring how breastfeeding duration is associated with how many children women go on to have. Our results show that women who breastfeed their first child for five months or longer are more likely to have three or more children, and less likely to have only one child, than women who breastfeed for shorter durations or not at all. Women who initiate breastfeeding did not differ in how many children they expected to have before they started their families. Rather, the number of children women actually bear differs by how long they breastfeed their first child. Women who breastfeed for shorter durations are more likely to have fewer children than they expected than to have more children than expected. In contrast, women who breastfeed longer are as likely to achieve their expectations as to exceed them, and they are nearly as likely to have more children than they expected as they are to have fewer.

Tina Shah, MD University of Chicago Medicine Department of Pulmonary and Critical Care University of ChicagoMedicalResearch.com Interview with: Tina Shah, MD University of Chicago Medicine Department of Pulmonary and Critical Care University of Chicago Medical Research: What is the background for this study? What are the main findings? Dr. Shah: The reason why we undertook this study is to better understand the Medicare COPD population that falls under the purview of the CMS Hospital Readmissions Reduction Program (HRRP). This program places up to a 3% penalty on all Medicare revenues for hospitals that take care of beneficiaries should a hospital exceed its “expected readmission rate.” Previously 30 day readmissions after index admissions for congestive heart failure, acute myocardial infarction and pneumonia fell subject to the HRRP. As of October 2014, COPD has been added to the list, despite minimal evidence to guide hospitals in how to curb COPD readmissions. The goal of this research was to provide an epidemiological background for this population and identify trends as a hypothesis generating first step to predict who is most likely to be readmitted and to identify targets for successful future interventions on this group. Our study population is unique in that we longitudinally look at about 1/2 of all Medicare admissions for COPD exacerbations, using the CMS guideline definition which is based on discharge ICD-9 codes. As described in previous literature, there is a large discrepancy between identification of COPD by provider versus coding algorithm, however since the Hospital Readmissions Reduction Program is based on discharge coding it is important to examine this particular group.

Sandra Goldsmith, MA, MS, RD Director of Public and Patient Education at Hospital for Special Surgery New York City.MedicalResearch.com Interview with: Sandra Goldsmith, MA, MS, RD Director of Public and Patient Education at Hospital for Special Surgery New York City. Medical Research: What is the background for this study? What are the main findings? Response: Almost 50 million adults in the United States suffer from some form of musculoskeletal disorder, which can affect their mobility and quality of life. Osteoarthritis (OA) is the leading cause of disability in the U.S. and affects more than 70 percent of adults between the ages of 55 and 78. Research has shown that there is a connection between being physically active and maintaining joint health, pain relief and improved quality of life. This study attempts to support the efficacy of Hospital for Special Surgery’s hospital-based exercise programs in increasing physical activity and improving quality of life through pain relief and improved stiffness, fatigue and balance in the older adult community. This study found that after taking the exercise classes, fewer participants reported experiencing a high level of muscle/joint pain from their condition (56 percent before the program started vs. 47 percent after completing the program). The study also reported improved quality of life, as evidenced by statistically significant reductions in how much their pain interfered with their general activities, ability to walk, mood, sleep and enjoyment of life. In addition, 83 percent of participants indicated a reduction in stiffness; 82 percent said they felt their balance improved; and 67 percent said they experienced less fatigue as a result of taking part in the program. Health outcomes were also related to the type of exercise class participants chose, with the greatest reduction in muscle/joint pain reported by those who took t’ai chi.

MedicalResearch.com Interview with: Shabbir M. H. Alibhai, MD, MSc and Husayn Gulamhusein, BHSc Department of Medicine, University Health Network Toronto, Ontario, Canada Medical Research: What is the background for this study? What are the main findings? MedicalResearch: In 2009, we published a research letter in JAMA which examined the rate of bone mineral density (BMD) testing in men starting androgen deprivation therapy (ADT) in the province of Ontario, Canada, between 1995 and 2008. Despite being recommended as a tool to better characterize fracture risk and optimize bone health, use of bone mineral density testing was low throughout the study period. This current study focuses on another aspect of bone health, which is the use of bisphosphonates among men undergoing androgen deprivation therapy for prostate cancer. Bisphosphonates are generally safe and effective medications that can reduce fracture risk particularly in those at higher risk of future fracture. Throughout the 17-year study period, we found that rates of new prescriptions for bisphosphonates remained low. Even when focusing on those men who should be receiving bisphosphonates as per Canadian guidelines due to their high risk for future fracture, i.e. those with a prior fragility fracture or prior diagnosis of osteoporosis, prescription rates remained low. Moreover, in all three groups, new bisphosphonate prescriptions dipped between the 2007-09 and 2010-12 time periods. This may be partly due to recent negative media attention regarding the association of bisphosphonates with rare but serious side effects (i.e. osteonecrosis of the jaw and atypical femoral fracture).

What are the main findings? Dr. Kind: By way of background: Socioeconomic disadvantage is a complex theoretical concept which describes the state of being challenged by low income, limited education and substandard living conditions for both the person and his or her neighborhood or social network. It is plausible that disadvantage would influence rehospitalization because vulnerable patients depend upon their neighborhood supports for stability, generally, and these needs are likely to be increased after a hospitalization. Yet, it is difficult to assess socioeconomic disadvantage during clinical encounters, yet the ADI provides an option for beginning such a discussion. ADI or Area Deprivation Index is a composite measure of neighborhood disadvantage, similar to other geographic measures of disadvantage employed in other countries for resource planning and health policy development.

MedicalResearch.com Interview with: Eero Haapala, MSc in Exercise Medicine, BASc PhD student University of Eastern Finland,School of Medicine Institute of Biomedicine, Physiology Kuopio, Finland Medical Research: What are the main findings of the study? Answer: Our study is one of the first studies to investigate the different types of physical activity and sedentary behavior with academic achievement in children. Our main finding was that children who were more physically active during school recess were better readers in Grades 1-3 than less active children. We also found a direct relationship between physically active school transportation, which was mainly walking and cycling, and reading skills in boys. These findings suggest that particularly physical activity within a school day benefits academic achievement and that physical activity benefit academic achievement more in boys than in girls 6-8 years of age.

Daniel Rocke, MD Medical School University of Michigan Medical School Ann Arbor, 2009.MedicalResearch.com Interview with Daniel Rocke, MD Duke Medicine Department Otolaryngology MedicalResearch: What are the main findings of the study? Dr. Rocke: I think the main point is that, to quote the paper, "end-of-life decision making by patients with cancer and their caregivers is significantly affected by their preference for quality of life or quantity of life, but OHNS physicians’ decision making is not." This is important because physicians counseling patients making end-of-life decisions are coming at these decisions from a different perspective that may not line up with their patients. If physicians recognize this, I think that these end-of-life discussions can be more productive

Carlos J. Rodriguez, MD, MPH Department of Medicine and Public Health Sciences, Wake Forest University School of Medicine, Winston-Salem, North CarolinaMedicalResearch.com Interview with Carlos J. Rodriguez, MD, MPH Department of Medicine and Public Health Sciences, Wake Forest University School of Medicine, Winston-Salem, North Carolina MedicalResearch: What are the main findings of the study? Dr. Rodriguez: As a clinician there is a notion suggesting that lower blood pressure is better but our current research to date is controversial and not conclusive. We wanted to study a large group of people with hypertension and see whether over 20 years of follow up, if a lower systolic blood pressure would be associated with lower cardiovascular events (heart attack, stroke, heart failure, angina). We hypothesized that there would be a linear association between blood pressure and events, that lower blood pressure would be associated with lower events and that as the blood pressure went up there would be more events. We found this was not the case but that hypertensives with a blood pressure between 120-138mmhg have the greatest benefit and those with a blood pressure less than 120mmhg did not have additional benefit.
