Response: We found that the rates of TAVR were lower in areas with higher proportions of Black, Hispanic and socioeconomically disadvantaged patients. Inequities in access in areas with higher proportions of Black and Hispanic patients existed despite adjusting for socioeconomic status.
Author Interviews, Brigham & Women's - Harvard, Heart Disease, JAMA, Lipids / 16.11.2021

MedicalResearch.com Interview with: [caption id="attachment_58380" align="alignleft" width="200"]Nicholas A. Marston, MD, MPH Thrombolysis in Myocardial Infarction (TIMI) Study Group Brigham and Women’s Hospital Harvard Medical School Boston, Massachusetts Dr. Marston[/caption] Nicholas A. Marston, MD, MPH Thrombolysis in Myocardial Infarction (TIMI) Study Group Brigham and Women’s Hospital Harvard Medical School Boston, Massachusetts MedicalResearch.com: What is the background for this study? Response: There has been recent debate about how much of lipid-associated cardiovascular risk is from LDL cholesterol versus triglycerides. However, genetic studies suggest that apolipoprotein B is actually the primary driver of atherosclerotic risk. Since there is exactly one apoB lipoprotein on each lipid particle (LDL, IDL, VLDL), its measurement is a surrgate for the total number of apoB-containing lipoproteins. So in this study, we asked the question: Do common measures of cholesterol concentration, triglyceride concentration, or their ratio carry predictive value for cardiovascular risk beyond the number of apo-B containing lipoproteins?
Alzheimer's - Dementia, Author Interviews, Biomarkers / 11.11.2021

MedicalResearch.com Interview with: [caption id="attachment_58375" align="alignleft" width="200"]Joshua Grill, PhD Professor, Psychiatry & Human Behavior School of Medicine Professor, Neurobiology and Behavior School of Biological Sciences University of California, Irvine Dr. Grill[/caption] Joshua D. Grill, PhD Professor, Psychiatry & Human Behavior School of Medicine Professor, Neurobiology and Behavior School of Biological Sciences University of California, Irvine MedicalResearch.com: What is the background for this study? Response: Alzheimer’s disease is a major public health challenge. More than 6 million Americans have the disease, which causes cognitive problems and eventual dependence on others for daily function. Scientists understand that the disease begins in the brain years before memory and other thinking problems begin and the AHEAD Study aims to intervene in this window of time, to see if a drug that targets these brain changes can delay or prevent symptoms of the disease.  
Author Interviews, Cancer Research, Dermatology, Lancet, Melanoma, Technology / 11.11.2021

MedicalResearch.com Interview with: [caption id="attachment_58371" align="alignleft" width="150"]Dr David Wen BM BCh NIHR Academic Clinical Fellow in Dermatology University of Oxford Dr. Wen[/caption] Dr David Wen BM BCh NIHR Academic Clinical Fellow in Dermatology University of Oxford MedicalResearch.com: What is the background for this study? Response: Publicly available skin image datasets are commonly used to develop machine learning (ML) algorithms for skin cancer diagnosis. These datasets are often utilised as they circumvent many of the barriers associated with large scale skin lesion image acquisition. Furthermore, publicly available datasets can be used as a benchmark for direct comparison of algorithm performance. Dataset and image metadata provide information about the disease and population upon which the algorithm was trained or validated on. This is important to know because machine learning algorithms heavily depend on the data used to train them; algorithms used for skin lesion classification frequently underperform when tested on independent datasets to which they were trained on. Detailing dataset composition is essential for extrapolating assumptions of generalisability of algorithm performance to other populations. At the time this review was conducted, the total number of publicly available datasets globally and their respective content had not previously been characterised. Therefore, we aimed to identify publicly available skin image datasets used to develop ML algorithms for skin cancer diagnosis, to categorise their data access requirements, and to systematically evaluate their characteristics including associated metadata.  
Author Interviews, Genetic Research, NEJM / 10.11.2021

MedicalResearch.com Interview with: [caption id="attachment_58367" align="alignleft" width="200"]Professor Sir Mark Caulfield Professor of Clinical Pharmacology William Harvey Research Institute Queen Mary University of London Professor Sir Caulfield[/caption] Professor Sir Mark Caulfield Professor of Clinical Pharmacology William Harvey Research Institute Queen Mary University of London  MedicalResearch.com: What is the background for this study? Response: Rare diseases affect 6% of the population in western nations and there are approximately 10,000 different disorders and many remain without a genomic diagnosis after usual testing during their life time. In 2013 the UK Government launched the 100,000 Genomes Project and created Genomics England to investigate the role of whole genome sequencing in rare disease, cancer and infection. Whole genome sequencing gives the most comprehensive read out of the entire genome. To do this we partnered with the National Institute for Health Research (NIHR) BioResource and 9 hospitals across England1. Our New England Journal of Medicine paper published on the 11th November 2021 reports findings on the early rare disease participants who helped us pilot procedures and processes that would be used to enrol at scale across the NHS and revealed the potential benefits for rare disease1.
Anesthesiology, Author Interviews, COVID -19 Coronavirus, Science, UCSF / 10.11.2021

MedicalResearch.com Interview with: [caption id="attachment_58364" align="alignleft" width="150"]Art Wallace, M.D., Ph.D. Professor Emeritus, Anesthesia School of Medicine, UCSF Chief of the Anesthesia Service Veterans Affairs Medical Center in San Francisco Dr. Wallace[/caption] Art Wallace, M.D., Ph.D. Professor Emeritus, Anesthesia School of Medicine, UCSF Chief of the Anesthesia Service Veterans Affairs Medical Center in San Francisco MedicalResearch.com: What is the background for this study? Response: I have spent the last 30 years working on perioperative risk reduction, developing medications and approaches to risk reduction. Part of this work utilized epidemiologic analysis of medication patterns of use to test if they are associated with reductions in morbidity and mortality. This work analyzed data in the VA Corporate Data Warehouse (CDW) which provides access to the VA, best in the world electronic health care record system, VISTA.  With the COVID-19 pandemic I realized that the analytic techniques we had utilized for perioperative cardiac risk reduction could be used to search for medications to reduce the risks for acute COVID-19 infection. We identified four classes of medications that reduced the risk of death in acute COVID-19 infection. We then turned our attention to medications to reduce the incidence, severity, and duration of long-term sequelae of COVID-19 infection also known as Long COVID or COVID Long Hauler Syndrome. One of the questions that people were asking was what was the effect of vaccination on Long COVID? We began that work by looking at the effect of vaccination on COVID infections and found the dramatic decrease in efficacy of vaccines with the spread of the Delta Variant. We published this work to notify the public and public health community of the decreased efficacy of the vaccines in the face of the Delta variant and reiterate the need for secondary public health prevention measures such as masks, social distancing, vaccination, and boosters.
Author Interviews, Rheumatology / 10.11.2021

MedicalResearch.com Interview with: [caption id="attachment_52102" align="alignleft" width="200"]Kelly Gavigan, MPH Manager, Research and Data Science CreakyJoints  Kelly Gavigan[/caption] Kelly Gavigan, MPH Manager, Research and Data Science CreakyJoints and Global Healthy Living Foundation MedicalResearch.com: What is the background for this study? Response: We understood that COVID-19 is of particular concern for people living with autoimmune and rheumatic disease because they are at increased risk of infection, and this created a heightened sense of isolation due to the strict social distancing protocols that so many patients have followed. As a result, we wanted to better understand if symptoms among the autoimmune and rheumatic disease patients in our ArthritisPower research registry were impacted throughout the COVID-19 pandemic. We analyzed patient reported outcome scores for mental, social, and physical health measures between the months of January 2020 and April 2021. We tested the null hypothesis that there was no change in monthly average assessment scores across the 15-month observation period.

MedicalResearch.com Interview with: [caption id="attachment_58359" align="alignleft" width="200"]Courtney K. Wells, PhD, MSW, MPH, LGSW Assistant Professor & Field Coordinator Department of Social Work University of Wisconsin-River Falls and member of CreakyJoints Dr. Wells[/caption] Courtney K. Wells, PhD, MSW, MPH, LGSW Assistant Professor & Field Coordinator Department of Social Work University of Wisconsin-River Falls and member of CreakyJoints MedicalResearch.com: What is the background for this study? Response: This study was initiated because early in the pandemic there was little information available regarding quality of life and the day-to-day activities of patients with rheumatic conditions. We were particularly interested in patients’ psychosocial experiences and how they made decisions about their health. We found that participants’ understanding of their risk for COVID-19 played a key role in their decision making processes. At the beginning of the pandemic, many participants viewed themselves as being high risk because of their condition and/or medications and took extreme precautions. These precautions isolated them from their family, friends, and healthcare, all of which negatively affected their physical and mental health. As the pandemic went on, participants described an exhausting balancing act between their risk for COVID-19, their rheumatic condition, and their mental health. Because we did interviews over 6 months, we saw participants shifting their priorities towards their mental health as more information became available and the vaccine emerged. We also learned that rheumatology patients from BIPOC ( Black, Indigenous, People of Color) and immigrant communities experienced unique stressors during the pandemic such as barriers to accessible and trusted healthcare providers and increased experiences of racism.
Author Interviews, Coffee, Heart Disease, JAMA, OBGYNE / 09.11.2021

Hinkle, PhD Assistant Professor Department of Biostatistics, Epidemiology and Informatics Perelman School of Medicine, University of Pennsylvania Dr. Hinkle[/caption] Stefanie N. Hinkle, PhD Assistant Professor Department of Biostatistics Epidemiology and Informatics Perelman School of Medicine University of Pennsylvania MedicalResearch.com: What is the background for this study? Response: Over 80% of U.S. women of reproductive age consume caffeine daily.While most women decrease consumption after becoming pregnant, many continue to consume caffeine throughout pregnancy. The American College of Obstetricians and Gynecologists (ACOG) recommends that pregnant women limit their caffeine consumption to <200 mg/d out of an abundance of caution due to potential associations with pregnancy loss and fetal growth restriction at higher intakes. There remains limited data on associations with maternal cardiometabolic outcomes in pregnancy.

Response: Microinflammation may be a mechanism contributing to adverse outcomes in patients with chronic kidney disease (CKD). Low dose aspirin (ASA) is usually used as an antiplatelet agent for cardiovascular indications, but may also have beneficial effects on kidney function by reducing microinflammation. 
Lifestyle & Health / 08.11.2021

Why Early Detection is a Life-saverIt's understandable if you fear visiting the hospital if you feel unwell. You worry that you will get a terrible diagnosis. You would rather pretend that everything is okay than face the truth. Remember that it's better to have early detection of an illness than waiting until everything is late. People's lives were saved because they decided to ask for medical advice early. You can begin your path to recovery Just because you received an unfavorable diagnosis doesn't mean your life is over. Even some life-threatening conditions like cancer already have a cure. Many people underwent remission after months or years of treatment. If you decide against getting medical advice, these potential cures might not work anymore. You will regret not starting the process earlier on.
Author Interviews, Weight Research / 07.11.2021

MedicalResearch.com Interview with: Neha Agrawal PhD Department of Physiology Development and Neuroscience University of Cambridge MedicalResearch.com: What is the background for this study? Response: Obesity levels are rising rapidly around the world and are a major risk factor for diseases such as Type 2 diabetes, cancers and recently, COVID-19. New strategies to understand obesity are thus needed to prevent and treat obesity and associated disease. Genetic studies in humans have shown that 40-70% of variation in body weight depends on our genes. Therefore, identifying genes linked to obesity and understanding their function can be a useful way to both understand how we gain weight and identify potential targets for weight loss therapy. However, human genetic obesity studies face significant limitations in identifying causal obesity genes and understanding their relationship to weight gain in human patients. The model system Drosophila melanogaster (Fruit flies) has provided vital insights into fundamental biology and human diseases for over a century. It is a powerful genetic model with well conserved metabolic pathways. Fruit flies also gain weight when fed a high-sugar or high-fat diet and develop heart disease and diabetes. We therefore decided to use fruit flies to identify novel obesity genes and their site of action in the body.

Response: The VA operates a very robust, embedded quality improvement and implementation science program, of which our team is involved. As the VA was one of the first US healthcare systems to rollout COVID-19 vaccination programs, we were asked to evaluate these efforts in real-time, to provide input to VA healthcare leaders on what was going well and what could be improved. This survey reported in JAMA Network Open is one of the quality improvement efforts we engaged in.

Response: We decided to review the evidence for zinc in response to calls for rapid evidence reviews to inform self-care and clinical practice during the COVID-19 pandemic. Laboratory studies have found that zinc can inhibit the replication of many respiratory viruses, including SARS-CoV-2 and other coronaviruses. Zinc plays a key role in immunity, inflammation, tissue injury, ACE-2 receptor activity, and also in tissue responses to a lack of oxygen. Low zinc status may be a risk factor for severe SARS-CoV-2 illness. Additionally, there was some indirect evidence suggesting zinc might be effective for other respiratory tract infections such as the common cold and we wanted to verify this.
Accidents & Violence, Addiction, Author Interviews, OBGYNE / 02.11.2021

MedicalResearch.com Interview with: [caption id="attachment_58300" align="alignleft" width="100"]Jeffrey Howard, PhD Associate Professor Department of Public Health College for Health, Community and Policy University of Texas at San Antonio Dr. Howard[/caption] Jeffrey Howard, PhD Associate Professor Department of Public Health College for Health, Community and Policy University of Texas at San Antonio MedicalResearch.com: What is the background for this study? Response: Drug and alcohol related mortality has been on the rise in the US for the past decade, which has drawn a lot of focus from researchers.  At the same time maternal mortality, deaths caused by pregnancy complications, is recognized to be higher in the US than in other developed nations. Very little has been reported about deaths among pregnant and recently pregnant women that are not caused by pregnancy complications, so my collaborators and I wanted to explore this.  We did not anticipate that drug and alcohol deaths and homicides would account for so many deaths among pregnant and recently pregnant women.
Author Interviews, Cancer Research, COVID -19 Coronavirus, Race/Ethnic Diversity, Radiation Therapy / 01.11.2021

MedicalResearch.com Interview with: [caption id="attachment_58308" align="alignleft" width="200"]Brianna M. Jones, MD Radiation Oncology Resident Icahn School of Medicine at Mount Sinai Dr. Jones[/caption] Brianna M. Jones, MD Radiation Oncology Resident Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? Response: The COVID-19 pandemic has resulted in over 4 million deaths worldwide and, presently, there have been over 2 million cases diagnosed in New York. There have been numerous studies that demonstrate cancer patients are at increased risk of diagnosis and mortality to SARS-CoV-2 virus. Several studies have also noted socioeconomic status and race/ethnicity are associated with poorer outcomes. Within NYC, Elmhurst Hospital Center (EHC) emerged as an early epicenter in spring of 2020. The surrounding catchment area of EHC consists of a population that is 54% Latino, 33% Asian, 6% White, 4% Black, 1% Native American, and 1% other according to U.S. Census Bureau, making it one of the most racially and ethnically diverse populations in the country. Its residents are predominantly working-class immigrants with limited resources that work jobs now considered essential (e.g., delivery workers, grocery shops, et cetera). EHC continued to offer a range of cancer services throughout the pandemic. Given the high infection rate and diverse population at EHC, our study provides an opportunity to evaluate outcomes in one of the hardest hit communities to date. Therefore, our aim was to investigate patient characteristics, clinical outcomes, and predictors of COVID-19 diagnosis, severity, and mortality in patients with an active cancer diagnosis at EHC. 
Asthma, Author Interviews, NEJM / 27.10.2021

MedicalResearch.com Interview with: [caption id="attachment_58297" align="alignleft" width="150"]Prof. Brightling Prof. Brightling[/caption] Professor Chris Brightling, NIHR Senior Investigator Department of Respiratory Sciences University of Leicester Leicester, UK MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Risankizumab is an anti-IL23 monoclonal antibody. It is a very effective licensed therapy for plaque psoriasis. IL23 has been implicated in asthma and therefore we chose to study the effect of risankizumab in people with severe asthma. The time to first asthma worsening was earlier and the frequency of asthma worsenings was higher in those treated with risankizumab versus placebo. We found that the gene expression of key molecules involved in the response to infection were decreased in airway samples in those treated with risankizumab. It is possible that the increased asthma worsening following risankizumab was related to this suppression of anti-microbial immunity. 
Author Interviews, Infections, JAMA, Multiple Sclerosis, Neurological Disorders / 27.10.2021

MedicalResearch.com Interview with: [caption id="attachment_58239" align="alignleft" width="200"]Scott Montgomery Professor of medical science (clinical epidemiology) Örebro University, Sweden Director of Clinical Epidemiology and Biostatistics Örebro University Hospital, Sweden Prof. Montgomery[/caption] Prof. Scott Montgomery Professor of medical science (clinical epidemiology) Örebro University, Sweden Director of Clinical Epidemiology and Biostatistics Örebro University Hospital, Sweden MedicalResearch.com: What is the background for this study? Response: Infections have been linked with increased risk of subsequent multiple sclerosis (MS), but it has been suggested this may be because the genetic or other family characteristics of people who go on to develop MS have a more severe response to infections: the infections would be more likely to be recorded in those who would subsequently develop MS, rather than being risk factors for the disease. To address this issue, we performed a large study of 2,492,980 people living in Sweden, and 5,867 of them had a diagnosis of MS after age 20 years. We identified who had a hospital diagnosis of infectious mononucleosis (caused by Epstein-Barr virus, EBV infection, and also known as glandular fever or the kissing disease). The new study was different from other studies of infection and MS risk, as it compared siblings in the same families. Siblings share much of their genetic make-up and have similar family lives. If glandular fever is associated with later MS when siblings are compared, then it is unlikely that the association is caused by genetics or other family characteristics that make infections worse in people more likely to develop future MS.
Author Interviews, Macular Degeneration, Ophthalmology, PNAS / 27.10.2021

MedicalResearch.com Interview with: [caption id="attachment_58321" align="alignleft" width="200"]Bradley D. Gelfand PhD Center for Advanced Vision Science Department of Ophthalmology Department of Biomedical Engineering University of Virginia School of Medicine Charlottesville, VA 22908 Dr. Gelfand[/caption] Bradley D. Gelfand PhD Center for Advanced Vision Science Department of Ophthalmology Department of Biomedical Engineering University of Virginia School of Medicine Charlottesville, VA 22908  MedicalResearch.com: What is the background for this study? Would you briefly describe dry AMD? Response: Dry age-related macular degeneration (AMD) is a form of AMD that affects about 11 million people in the United States, and many millions more worldwide. Dry AMD is a disease affecting the macula, the central part of our retina that is responsible for fine visual acuity tasks - things like reading, driving, and recognizing faces. Dry AMD typically develops in people in their 6th, 7th, and 8th decades of life and begins with small changes to the retina that are unlikely to affect vision at first. As the disease progresses, it can develop into more advanced stages ("wet" AMD and geographic atrophy), which can cause blindness. Unfortunately, there is no approved treatment that can prevent dry AMD or its progression to advanced blinding stages.

MedicalResearch.com Interview with: [caption id="attachment_58312" align="alignleft" width="200"]Joel S. Weissman, PhD Deputy Director/Chief Scientific Officer Center for Surgery and Public Health Brigham and Women's Hospital/Harvard Medical School Professor of Surgery (Health Policy) Harvard Medical School Dr. Weissman[/caption] Joel S. Weissman, PhD Deputy Director/Chief Scientific Officer Center for Surgery and Public Health Brigham and Women's Hospital/Harvard Medical School Professor of Surgery (Health Policy) Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Over time, the military health system has been shifting care for its soldiers and their families away from big military treatment facilities (MTFs), allowing soldiers and their families to get care from civilian hospitals.  But this has had an unintended consequence.  Unfortunately, it means that military surgeons are getting fewer cases, and they are worried about maintaining their skills as surgeons.  But some surgeries count more than others to help prepare the surgeon for battlefield casualties. 
Author Interviews, Cancer Research / 27.10.2021

MedicalResearch.com Interview with: [caption id="attachment_58316" align="alignleft" width="200"]Shoshana Rosenzweig Medical Student at the Icahn School of Medicine at Mount Sinai Shoshana Rosenzweig[/caption] Shoshana Rosenzweig Medical Student Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? Would you briefly describe the Phantosmia phenomenon?  Response: Phantosmia is an olfactive disorder resulting in the perception of a foul-smelling odor without odorant stimulus. This study was spearheaded by Dr. Suzanne Wolden, a pediatric radiation oncologist and the senior author of the research. She noticed that patients receiving proton beam therapy were complaining of this phenomenon more than her patients receiving photon therapy. Through this research, the team hoped to characterize radiation treatment induced phantosmia in pediatric, adolescent and young adult patients treated with proton beam therapy and we hoped to identify potential clinical and treatment-related characteristics that may correlate with the development of phantosmia. 
Author Interviews, Cannabis, JAMA, Pediatrics / 25.10.2021

MedicalResearch.com Interview with: Carmen Lim BSc(Hons), MSc, CStat PhD Candidate National Centre for Youth Substance Use Research Faculty of Health and Behavioural Sciences The University of Queensland Brisbane Australia MedicalResearch.com: What is the background for this study? What are the main findings? Response: This review has systematically summarized the trends and products used for cannabis vaping using 17 studies published globally between Jan 1, 2003 and August 19, 2020. The pooled prevalence has increased for lifetime use (6.1% in 2013 to 13.6% in 2020), past-year use (7.2% in 2017 to 13.2% in 2020) and past-month use (1.6% in 2013 to 8.4% in 2020). Adolescents' preference for cannabis products may be shifting from less potent products (e.g., herbal cannabis) to highly potent vape oil and concentrates.

Author Interviews, Blood Pressure - Hypertension, Pulmonary Disease, University of Pittsburgh / 22.10.2021

MedicalResearch.com Interview with: [caption id="attachment_58271" align="alignleft" width="200"]Dr. Chan - UPMC Image Dr. Chan - UPMC image[/caption] Stephen Chan, M.D., Ph.D. Professor of Medicine Director of the Vascular Medicine Institute at Pitt and UPMC MedicalResearch.com: What is the background for this study? Response: Pulmonary hypertension (PH) is a type of high blood pressure that occurs in the vessels that transport blood from the heart to the lungs. As the disease progresses and the heart must strain harder against these high pressures, it can lead to heart failure, multi-organ dysfunction and death. PH affects people of all ages but hits young women more often than men. Pulmonary hypertension is an example of a rare disease where there is an unmet need for new treatments, given its devastating consequences. Repurposing drugs that are already in use for other purposes can dramatically cut down the time and cost of developing treatments for rare diseases like PH. But a pipeline to predict and test for drugs in this way for PH and other rare diseases has not been described.

Hershey Medical Center Hershey, Pennsylvania  MedicalResearch.com: What is the background for this study? Response: Most people who get sick from COVID-19 will survive. However, the burden of long-term consequences among the survivors is not well-characterized. That is what inspired this study.  MedicalResearch.com: What are the main findings? Response: After compiling data from 57 studies involving 250,351 unvaccinated individuals, our study shows that more than half of those worldwide who have been diagnosed with COVID-19 experience six months after recovering. The most common sequelae involve functional mobility impairments, pulmonary abnormalities, and mental health disorders, including memory deficits, concentration difficulty, post-traumatic stress disorders, depression, and anxiety.
Author Interviews, COVID -19 Coronavirus, Statins / 22.10.2021

MedicalResearch.com Interview with: Rita Bergqvis Department of Global Public Health Karolinska Institutet Stockholm, Sweden MedicalResearch.com: What is the background for this study? Response: There is a theoretical background for the discussion regarding statins in relation to COVID. Hyperinflammation and hypercoagulability have been identified as central to the development of severe COVID and COVID related complications. Hence, drugs that modulate the host immune response and inhibit thrombosis and vascular dysfunction have received a lot of attention. Statins are known to have pleiotropic effects; apart from their cholesterol lowering properties they are thought to modulate immune system processes and decrease the risk of thrombotic events. Previous observational studies on statins and COVID had some major methodological limitations and showed varying results.

What are the main findings? Response: The expectation for new cancer drugs is that they help patients live better longer. Increasingly more cancer drugs are approved without documented quality of life or overall survival benefits.   At the same time, cancer drug prices are rising.  We studied use of and spending on selected new cancer drugs among patients with employer-sponsored health insurance. We found that among 37348 patients who received one or more of 44 oral targeted cancer drugs, the proportion of patients who received a drug without documented overall survival benefit increased from 13% in 2011 to 59% in 2018.  By 2018, spending on drugs without documented overall survival benefit accounted for 52% of the $3.5 million spend on the 44 drugs since 2011.
