MedicalResearch.com Interview with: [caption id="attachment_53969" align="alignleft" width="200"]Rebecca Vigen, MD, MSCS Assistant Professor of Internal Medicine UT Southwestern Dr. Vigen[/caption] Rebecca Vigen, MD, MSCS Assistant Professor of Internal Medicine UT Southwestern MedicalResearch.com: What is the background for this study? Response: Emergency department overcrowding is an urgent health priority and chest pain is a common reason for emergency department visits.  We developed a new protocol that uses high sensitivity cardiac troponin testing with a risk assessment tool that guides decisions on discharge and stress testing for patients presenting with chest pain. The protocol allows us to rule out heart attacks more quickly than the protocols utilizing an older troponin assay.

MedicalResearch.com Interview with: [caption id="attachment_53964" align="alignleft" width="200"]Alex Hollingsworth PhD Assistant Professor O'Neill School of Public and Environmental Affairs Indiana University Dr. Hollingsworth[/caption] Alex Hollingsworth PhD Assistant Professor O'Neill School of Public and Environmental Affairs Indiana University MedicalResearch.com: What is the background for this study? What are the main findings? Response: I've been working with Coady Wing and Ashley Bradford on a few different studies of the effects of recreational marijuana laws on drug and alcohol use. Soon after EVALI became a major issue, the prevailing theory from the CDC and others was that EVALI was caused by the use of vitamin E acetate in illegal THC vaping products. Our group read about this and we thought about some of the things that often happen in black markets for illegal drugs. For instance, during the alcohol prohibition era, bootleg alcohol producers often made and sold alcohol products that were not that safe to drink. In more recent years, there are cases where black market sellers of illegal drugs like heroin try to increase profit margins by adding other substances, which can be harmful. We thought that maybe something like that could be happening in EVALI. Perhaps people in states where recreational marijuana is legal tended to purchase marijuana products from the legal market and the legal market was not selling any marijuana vaping products that included vitamin E acetate.
COVID -19 Coronavirus, FDA / 21.04.2020

'The U.S. Food and Drug Administration authorized the first diagnostic test with a home collection option for COVID-19. Specifically, the FDA re-issued the emergency use authorization (EUA) for the Laboratory Corporation of America (LabCorp) COVID-19 RT-PCR Test to permit testing of samples self-collected by patients at home using LabCorp’s Pixel by LabCorp COVID-19 Test home collection kit. “Throughout this pandemic we have been facilitating test development to ensure patients access to accurate diagnostics, which includes supporting the development of reliable and accurate at-home sample collection options,” said FDA Commissioner Stephen M. Hahn, M.D. “The FDA’s around-the-clock work since this outbreak began has resulted in the authorization of more than 50 diagnostic tests and engagement with over 350 test developers. Specifically, for tests that include home sample collection, we worked with LabCorp to ensure the data demonstrated from at-home patient sample collection is as safe and accurate as sample collection at a doctor’s office, hospital or other testing site. With this action, there is now a convenient and reliable option for patient sample collection from the comfort and safety of their home.”

MedicalResearch.com Interview with: [caption id="attachment_53956" align="alignleft" width="150"] Dr. Döhla[/caption] Dr. med. Manuel Döhla Associate Researcher, AG "One Health" Institute for Hygiene and Public Health Medical Faculty, University of Bonn Bonn, Germany MedicalResearch.com: What is the background for this study? Response: Rapid and reliable testing of suspected cases is an important measure in the fight against the corona pandemic. In PCR diagnostics, 24 hours and sometimes more elapse between testing and notification of the test result. During this period, suspect cases must be isolated pre-emptively so that they do not cause further transmission. This is logistically and personnel-intensive and highly error-prone. The shorter the time between test and result, the more effective containment measures can be. This is why the test we have evaluated, which shows a result within 20 minutes, has aroused our interest. The manufacturer's specifications (sensitivity 70 % in early stage disease (day 4-10), 100 % in late stage disease (day 11-24), specificity 100 %) were promising.
Author Interviews, Cognitive Issues, Mediterranean Diet, NIH / 21.04.2020

MedicalResearch.com Interview with: [caption id="attachment_48090" align="alignleft" width="150"]Emily Y. 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.

MedicalResearch.com Interview with: Barbara Chaiyachati, MD PhD SafePlace: The Center for Child Protection and Health Division of General Pediatrics The Children’s Hospital of Philadelphia, Center for Pediatric Clinical Effectiveness University of Pennsylvania Philadelphia, Pennsylvania MedicalResearch.com: What is the background for this study? What are the main findings? Response: Children in foster care have high rates of medical problems including chronic diseases. There is less known about the differences in mortality for children in foster care. Looking at national data from 2003 to 2016, this study finds that children (ages 1 to 18) in foster care have higher mortality compared to children in the general population and that the difference in mortality has increased over time.

Response: As some health care systems approach collapse, a pressing need exists for tools modeling the capacity of acute and critical care systems during the COVID-19 pandemic. We developed an online tool to estimate the maximum number of COVID-19 cases that could be managed per day within the catchment area served by a health care system, given acute and critical care resource availability. The COVID-19 Acute and Intensive Care Resource Tool (CAIC-RT) is open access and available at https://caic-rt.shinyapps.io/CAIC-RT.

Response: Aspirin has been known since long time to have a beneficial effect in the primary and secondary prevention of cardiovascular diseases. Additional evidence indicates that it has also a favorable role on the risk of various cancers.
Author Interviews, COVID -19 Coronavirus, Rheumatology / 16.04.2020

MedicalResearch.com Interview with: [caption id="attachment_53923" align="alignleft" width="138"]Ellen M. Gravallese M.D. President, American College of Rheumatology Dr. Gravallese[/caption] Ellen M. Gravallese M.D. President, American College of Rheumatology Dr. Gravallese discusses the recent guidance document issued by ACR for the treatment of rheumatic disease patients during the COVID-19 pandemic. MedicalResearch.com: What is the background for this announcement? Are patients with rheumatic disease at greater risk of severe illness or death from the SARS-CoV-2 virus?  Response: This week the ACR issued a guidance document that is the product of the ACR’s Clinical Guidance Task Force, a newly appointed task force that includes experts in infectious disease, as well as experts in biologic and non-biologic rheumatic disease therapies. This clinical guidance document was prepared to assist rheumatology professionals in the care of their patients during this novel pandemic, and to advise as to how to handle rheumatic disease therapies. There is no data to suggest that patients with rheumatic disease are at greater risk of severe illness or death simply because they have a rheumatic disease. Rheumatic disease patients appear to be at risk for poor outcomes if they become infected primarily because of general risk factors such as older age or comorbid medical conditions, such as significant heart or lung disease. A global alliance has been created by the rheumatology community that has developed an international case-reporting registry to collect information pertinent to COVID-19 infection in patients with rheumatic disease. The ACR has played an active role in helping the Alliance get their message out to the rheumatology community, and we continue to support the Alliance with its data dissemination and communication efforts. We hope this registry will provide valuable data to address additional questions about the best way to manage rheumatology patients affected by COVID-19 and we encourage providers to submit their COVID-19-related cases to the Alliance website at www.rheum-covid.org.
Author Interviews, Neurological Disorders, Parkinson's / 15.04.2020

MedicalResearch.com Interview with: [caption id="attachment_53918" align="alignleft" width="200"]Dr. Viviane Labrie, PhD Dr. Labrie[/caption] Dr. Viviane Labrie, PhD Dr. Labrie is an associate professor in Van Andel Institute’s Center for Neurodegenerative Science, where she studies Parkinson’s, Alzheimer’s and other neurological diseases. MedicalResearch.com: What is the background for this study? Response: One of the most puzzling and persistent mysteries in neuroscience has been why some people are “right-brained” while others are “left-brained.” The two sides of the brain have different jobs. The left side is analytic and problem-solving, while the right side manages creativity and artistic talents. But despite their differences, the two sides are composed of the same cell types — essentially, brain neurons and their support cells. In this study, we sought to understand how it is possible for these cells to behave completely differently depending on what hemisphere they’re located in.  We also wanted to examine the reasons behind asymmetry in Parkinson’s disease; that is, why Parkinson’s symptoms typically start on one side of the body before the other. This asymmetry in neurodegeneration and symptoms in patients is one of the biggest unsolved puzzles in the Parkinson’s disease field — why do brain cells in one hemisphere begin dying before brain cells in the other hemisphere?

Response: This study resonates across nursing. Kat Siaron is a Neuroscience nurse who had questions about the ‘best’ location for checking blood pressure. Like so many studies this started with a clinical question: “does it make a difference where you check the blood pressure?” She applied for a nursing research fellowship and was one of 6 nurses selected. She spent about 3 months reading articles on blood pressure and looking to see if there are any similar studies. After confirming that this has not been done, she submitted her study for approval from the Institutional Review Board and started data collection.

Drucker, M.D. Lunenfeld-Tanenbaum Research Institute Mount Sinai Hospital Toronto  MedicalResearch.com: What is the background for this study? What are the main findings? Response: This review was prompted by shared mechanistic pathways linking actions of molecules such as ACE2 and DPP4, which are important enzymes with cardiometabolic actions, yet also function as coronavirus receptors. The recognition that people with diabetes and obesity are more prone to severe infection also highlights the importance of understanding the biology We highlight the intersection of pathways shared by coronavirus infection, and how these might impact our understanding of diabetes and its therapies.
Author Interviews, Diabetes, JAMA, Surgical Research / 14.04.2020

MedicalResearch.com Interview with: [caption id="attachment_53895" align="alignleft" width="200"]Katherine Moll Reitz, MD General Surgery Resident University of Pittsburgh Dr. Reitz[/caption] Katherine Moll Reitz, MD General Surgery Resident University of Pittsburgh MedicalResearch.com: What is the background for this study? Response: Surgical interventions both save lives and improve the quality of those lives each day. However, these same interventions and the recovery thereafter are a major physiologic stressor. Younger, more resilient patients tend to recover faster, with fewer postoperative complications when compared to older, frailer patients undergoing the same surgical treatments. Therefore, investigators at University of Pittsburgh and UPMC have begun focusing on prehabilitation in order to optimize at risk patients preoperatively. Just as an athlete would train for an upcoming event, prehabilitation (including smoking cessation, healthy eating, and physical activity increases) prepares or trains patients for their surgical intervention and can improve their postoperative outcomes. Currently, there is no medication available to aid in this training process, improving patients’ response to the physiologic stress of surgery. Therefore, we are interested in exploring potential safe, well tolerated medical therapies which can optimize patients as pharmacologic prehabilitation.

Would you briefly explain what is meant by PCOS? Response: Polycystic ovary syndrome (PCOS) is the most common hormone disorder in women of reproductive age.  It is characterized by high androgen levels (e.g., testosterone) in the blood and irregular menstrual cycles.  Despite affecting 5-15% of women, its cause is unknown.  While medications can be used to reduce androgen levels, or help achieve menstrual regularity or stimulate ovulation, these often have undesirable side effects.  Our goal was to investigate the effectiveness of non-pharmacologic approaches, including yoga, on improving the characteristics associated with the disorder.

What are the main findings? Response: The recent outbreak of pneumonia-causing COVID-19 pandemic is an urgent global public health issue. It is critical to understand and unravel the key difference of COVID-19 or SARS-CoV-2 with the previous coronavirus (SARS and MERS) infections. Specifically, structural and molecular dynamics which underline the mechanism of viral infection. The study first addresses the structure of COVID-19 spike glycoprotein in both closed (ligand-free) and open (ligand-bound) conformation, which open the arena in understating the viral attachment to the host cell. The study also provides the first and complete sequence alignment of spike glycol protein from COVID19 and SARA-1, showing novel insertions and deletions that highlights the uniqueness of COVID19 and underlies the differential interaction mode. The study also unravels how this new coronavirus camouflages in humans through its unique glycosylation of spike glycoprotein, which makes the most of neutralizing antibodies useless. Furthermore, In addition to known ACE2 receptor in human, the study discovers the human CD26 as another potential receptor of COVID-19 for host adhesion and hijacking.

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.

MedicalResearch.com Interview with: [caption id="attachment_53855" align="alignleft" width="146"]Nora D. Volkow, MD Director of the National Institute on Drug Abuse National Institutes of Health Bethesda, MD Dr. Volkow[/caption] Nora D. Volkow, MD Director of the National Institute on Drug Abuse National Institutes of Health Bethesda, MD MedicalResearch.com: What is the background for this study? How does vaping, hookah use, inhaled marijuana, smoking etc impact the risk of coronavirus infection?  Could these activities account for some the risks and infections in younger individuals?   Response: Apart from older age, having underlying cardiopulmonary conditions is a known risk factor for the worst clinical course and outcomes of COVID-19, and many of those conditions are known to be caused or exacerbated by smoking. While evidence continues to emerge about how smoking might interact with COVID-19, it is a reasonable assumption that smoking could contribute to risk even in younger individuals. We still don’t know how vaping—whether of nicotine or marijuana or just flavorings—contributes to the risk of infection or illness severity with the virus that causes COVID-19, but there are a number of reasons to be concerned. We have already seen lung illnesses caused by some vaping products, and evidence suggests vaping may disrupt lung epithelial cell function, which in turn increases viral susceptibility and may put individuals at increased risk of infection with the virus that causes COVID-19 or with more severe disease outcomes. Vaping is a relatively new technology, and as such, there are many unknowns. The rapid increases in vaping by young people over the last few years make this an area of concern, and thus an area where more research is urgently needed.

Response: It is well established that healthcare providers are sensitive to changes in price, though their behavioral response varies. Dialysis facilities are particularly responsive to changes in Medicare reimbursement. Many dialysis patients are eligible for Medicare regardless of age, but dialysis facilities generally receive significantly higher reimbursement from private insurers than from Medicare. In 2011, Medicare implemented a new prospective bundled payment for dialysis that was expected to decrease Medicare payment and reduce overall revenues flowing into facilities. Then the Affordable Care Act (ACA) rules against refusing to insure patients for preexisting conditions and the 2014 ACA Marketplace provided an additional avenue for patients to purchase private insurance. As a result of these policies, dialysis facilities had a strong motivation and opportunity to increase the share of patients with private insurance coverage. We were interested in understanding whether dialysis facilities were shifting their payer mix away from Medicare, possibly in response to these policy changes. 
ASCO, Author Interviews, Cancer Research, Journal Clinical Oncology / 10.04.2020

MedicalResearch.com Interview with: [caption id="attachment_53818" align="alignleft" width="130"]Matthew Galsky, MD Icahn School of Medicine at Mount Sinai New York, NY Dr. Galsky[/caption] Matthew Galsky, MD Icahn School of Medicine at Mount Sinai New York, NY MedicalResearch.com: What is the background for this study? Would you explain what is meant by switch maintenance immunotherapy? Response: For decades, platinum-based chemotherapy has been standard first-line treatment for metastatic urothelial (bladder) cancer. The standard approach to first-line chemotherapy is to administered approximately 6 cycles of treatment (in the absence of disease progression or prohibitive side effects), and then to stop treatment and monitor. Unfortunately, virtually all patients with metastatic disease will experience disease progression after stopping chemotherapy. However, we know that if we just continue the same platinum-based chemotherapy until progression of cancer (rather than stopping after ~6 cycles), the side effects continue to accumulate but the benefits plateau. Approximately 5 years ago, the first new systemic therapies were approved to treatment metastatic urothelial cancer in decades, immune checkpoint inhibitors (PD-1 or PD-L1 inhibitors). In fact, 5 PD-1/PD-L1 inhibitors have been approved by the FDA for the treatment of patients with metastatic urothelial cancer progressing despite prior platinum-based chemotherapy. Given that these drugs are non-cross resistant with chemotherapy in at least a subset of patients (i.e., they can provide benefit even when chemotherapy is no longer working), and because they are well tolerated by a large proportion of patients, a logical question is rather than waiting until cancer progresses after stopping first-line chemotherapy, what if we started immunotherapy immediately. Switch maintenance refers to switching from chemotherapy to a different class of drug (e.g., immunotherapy) and maintenance refers to trying to "maintain" the response achieved with initial chemotherapy.

Candidate, Department of Public Health Sciences, Queen’s University Kingston, ON, Canada MedicalResearch.com: What is the background for this study?
  • There has been much speculation into the existence of a withdrawal syndrome involving cannabis much like withdrawal syndromes from opioids or alcohol. Our goal for this study was to estimate the prevalence of cannabis withdrawal syndrome (CWS) and to identify any risk factors for CWS.
  • There has been a lot of research into cannabis withdrawal syndrome (CWS) in the past. A big part of this review involved understanding where the CWS field is in terms of the shared understanding on its epidemiology and physiology.
  • To that end, we were not surprised to find that the prevalence of cannabis withdrawal syndrome was high. However, we found that some of the characteristics of CWS are consistent with other substance use disorders, which really serves to legitimize the decision to classify CWS and cannabis use disorders as psychiatric conditions.

MedicalResearch.com Interview with: Zhen Yang MD PhD Department of Endocrinology, Xinhua Hospital Shanghai Jiao Tong University School of Medicine Shanghai, China   MedicalResearch.com: What is the background for this study? Response: Hypertension is a major public health problem affecting more than 1 billion people worldwide. And it is the leading cause of mortality and disability globally. Startlingly, more than half of people with elevated blood pressure were unaware of their hypertensive status in numerous surveys, partly owing to hypertension rarely shows symptoms in the early stages. Hence, hypertension is a silent killer.
