Author Interviews, COVID -19 Coronavirus, Pediatrics / 10.09.2020

MedicalResearch.com Interview with: Burak Bahar, MD Children’s National Hospital Laboratory Medicine Division Washington DC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Objective of this study was to help us better understand how long it takes pediatric patients with COVID-19 to clear it from their system, and at what point they start to make antibodies against the virus. Main findings of our study were 19.5 days being the median duration of viral positivity which is later than 18 days that is the median time for detecting antibodies in the circulation. We also found that kids aged 6 through 15 had a longer duration of viral positivity which was a median of 32 days. (more…)
Author Interviews, COVID -19 Coronavirus, Hospital Acquired, Infections, JAMA / 10.09.2020

MedicalResearch.com Interview with: Chanu Rhee MD MPH Associate Hospital Epidemiologist Attending Physician, Infectious Diseases and Critical Care Medicine Assistant Professor of Medicine Brigham and Women's Hospital MedicalResearch.com: What is the background for this study?   Response: Many patients have been avoiding essential care during the COVID-19 pandemic due to fear of contracting SARS-CoV-2 in healthcare settings. Little is known, however about the adequacy of infection control practices in preventing nosocomial COVID-19 in U.S. acute care hospitals. We therefore conducted this observational study to determine the incidence of nosocomial COVID-19 in patients hospitalized at a large academic medical center in Boston (Brigham and Women’s Hospital) during the first 12 weeks of the surge in Massachusetts.    (more…)

MedicalResearch.com Interview with: Funmi (Abiru) Obisesan, MD, MPH Postdoctoral Fellow Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease Postdoctoral Fellow Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease MedicalResearch.com: What is the background for this study? Response: E-cigarettes are conceived by many individuals to be less harmful than combustible cigarettes, resulting in their use among young individuals and other vulnerable subpopulations. The recent outbreak of EVALI (e-cigarette, or vaping, product-use associated lung injuries) which was directly associated with e-cigarette use, and the rapidly evolving e-cigarette market, as well as regulations concerning them necessitates the need for up-to-date analyses of e-cigarette use trends.  (more…)

MedicalResearch.com Interview with: Claudia Alteri, PhD Assistant Professor (RTD-B) in Microbiology And Clinical Microbiology Department of Oncology and Hemato-Oncology University of Milano  MedicalResearch.com: What is the background for this study? Response: In the context of SARS-CoV-2 diagnosis, laboratories play a critical role in confirming the initial clinical suspicion of this disease, as confirmation of SARS-CoV-2 presence is essential to ensure the prompt initiation of containment and treatment protocols. This is of utmost importance to avoid further spread of the pandemic, and to assure the best clinical and therapeutic management of the infected patients in the hospital setting. Unfortunately, currently used rtPCR assays lack of the necessary sensitivity to identify all cases of SARS-CoV-2 infection (20% of false negative results [Li D et all, Korean J Rad 2020; Zhao et all CID 2020]). Complementary laboratory assays are therefore strongly needed. Droplet Digital PCR (ddPCR) is a highly sensitive assay for the direct detection and quantification of DNA and RNA targets. It has been increasingly used in infectious disease settings, especially thanks to its ability to consistently and reliably detect down to few copies of viral genomes. Standing the necessity of a limitation (as much as possible) of false negative results in COVID-19 diagnosis, the use of ddPCR could provide a critical support. In the context of COVID-19 diagnosis, two recent studies highlight the good performances of ddPCR in detecting low viral load samples (Suo T MedRxiv 2020; You F MedRxiv 2020)  (more…)

Annals Internal Medicine, Author Interviews, CDC, COVID -19 Coronavirus / 09.09.2020

MedicalResearch.com Interview with: Dr. Nathan Furukawa, MD, MPH Medical officer, Division of HIV/AIDS Prevention CDC MedicalResearch.com: What is the background for this study? Response: The cost of the PrEP medication is the largest driver of the cost of providing PrEP care. Most patients need insurance or help from a medication assistance program to cover the large costs of the PrEP medication. We wanted to describe how these costs were paid by patients (out-of-pocket payments) and insurers (third-party payments) nationally.    MedicalResearch.com: What are the main findings? Response: The study found that the cost for a month of the PrEP medication tenofovir disoproxil fumarate/emtricitabine increased from $1350 to $1638 from 2014 to 2018, an average annual increase of 5%. Out-of-pocket costs increased faster from $54 to $94, an average annual increase of 14.9%. In 2018, at least $2 billion was spent paying for the PrEP medication, and this covered 18% of people that had an indication for PrEP.  (more…)
Author Interviews, Health Care Systems, JAMA / 09.09.2020

MedicalResearch.com Interview with: Kenton J. Johnston, PhD Associate Professor Dept of Health Management & Policy Dept of Health & Clinical Outcomes Research Saint Louis University MedicalResearch.com: What is the background for this study? Response: Consolidation of physician practices into larger health systems comprised of hospitals and other group practices has been occurring rapidly in the U.S. market over the past 10 years. During this same period, Medicare has been gradually increasing the use of “pay for performance,” or “value-based payment” programs. 2019 was the first year that nearly all physicians in the U.S. were paid under Medicare’s new mandatory Merit-Based Incentive Payment System (MIPS). We conducted a study to see whether physicians who were affiliated with health systems performed better under the MIPS than those not affiliated with health systems. (more…)

MedicalResearch.com Interview with: Xiaoyan Song, PhD, MBBS, CIC Director, Office of Infection Control/Epidemiology Children's National Hospital Professor of Pediatrics George Washington University School of Medicine and Health Science Washington, D.C. 20010 MedicalResearch.com: What is the background for this study? Response: As soon as SARS-COV-2 virus began spreading in early January and raising concerns for a potential pandemic, both the public and healthcare providers have wondered how this new virus is compared to influenza, a virus that human has known for a century and has become much more familiar with its spread pattern, disease characteristics, and treatment. In contrast, we have very little knowledge about SARS-COV-2 and are still getting to know it little by little.  At Children’s National, we always maintain high vigilance on emerging infectious diseases and have excellent surveillance programs for influenza and other respiratory viral diseases.  Therefore, driven by 1) Our curiosity to know if SARS-COV-2 is indeed similar or different from influenza, and 2) Availability of both SARS-COV-2 and influenza data, we conducted this retrospective study.

MedicalResearch.com Interview with: Takanori Takebe MD Director for Commercial Innovation, Center for Stem Cell and Organoid Research and Medicine (CuSTOM) Assistant Professor, University Cincinnati Department of Pediatrics, Cincinnati Children’s Professor, Institute of Research Tokyo Medical and Dental University, Japan  MedicalResearch.com: What is the background for this study?  What are the main findings? Response: Drug induced liver injury (DILI) is rare yet highly unpredictable disorder that oftentimes causes drug failure withdrawn from the market during clinical trial even at a very rare incidence of DILI (1/10,000). Indeed, one particular drug TAK875 (Fasigliam) was the case despite promising efficacy. This not only disappoints patient but impact significant financial risk to pharmaceuticals. In collaboration with DILI genomics consortium at US, EU and UK, we’ve found +20,000 genetic make up (variants) defines potential risk of developing Drug induced liver injury thru amplifying cellular stress signal cascades that were investigated by human cell, organoid and patient datasets.

Author Interviews, Infections, JAMA / 08.09.2020

MedicalResearch.com Interview with: Yaa-Hui Dong PhD Faculty of Pharmacy National Yang-Ming University Taipei, Taiwan MedicalResearch.com: What is the background for this study? Response: Previous observational studies found that fluoroquinolones may be associated with more than 2-fold increased risk of aortic aneurysm or aortic dissection (AA/AD). However, these studies might not well address the influence of concurrent infection, which is also a suggested risk factor for AA. Moreover, most of these studies compared fluoroquinolone use versus no fluoroquinolone use, which might overestimate the risk with fluoroquinolones as patients on fluoroquinolones may have more severe infection versus those not on fluoroquinolones.

What are the main findings? Response: All states closed schools in the spring of 2020 to try to mitigate the spread of COVID-19. Our study demonstrated a large, significant association between school closure and fewer COVID-19 cases and deaths even when accounting for other state policies. (more…)
Author Interviews, Cannabis, Cognitive Issues, Memory, Pediatrics / 04.09.2020

MedicalResearch.com Interview with: Jarrod Ellingson PhD Assistant Professor Department of Psychiatry Anschutz Medical Campus University of Colorado Denver  MedicalResearch.com: What is the background for this study? What are the main findings? Response: We know that cannabis use is associated with many negative outcomes, but there could be many of reasons for that. For example, socioeconomic factors and peer influences both affect adolescent cannabis use and poorer cognitive functioning. To account for some of those risk factors, we studied nearly 600 sibling pairs with moderate to heavy cannabis use. We found that, as a person uses more cannabis than their sibling, they tend to have worse memory recall than their sibling. (more…)
Author Interviews, Brigham & Women's - Harvard, Cancer Research, Dermatology / 03.09.2020

MedicalResearch.com Interview with: Yin Zhang MD Research Fellow in Medicine Brigham and Women's Hospital and Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Among modern hair dyes, permanent hair dye is the most popular type, and is the most aggressive and extensively used type that has posed the greatest potential concern about cancer risk. Monitoring and investigating the carcinogenic hazard to people from personal use of permanent hair dyes has major public health implications. In 2008, the World Health Organization's International Agency for Research on Cancer, after comprehensive reviewed prior evidence, classified occupational exposure to hair dyes as a probable carcinogen to humans (group 2A), whereas personal use of hair dyes was not classifiable as to its carcinogenicity to humans (Group 3). Data on hair dye safety has also been continuously monitored by the USFDA. Prior epidemiological evidence may have been influenced by not discriminating between personal and occupational exposure, an inability to distinguish types and colors of hair dyes used, imprecise assessment of several critical domains of exposure history (duration, frequency and cumulative dose), and inadequate control for potential confounding.

MedicalResearch.com Interview with: Kyla Fergason Senior Undergraduate Student Michael K. Scullin, Ph.D. Principal Investigator Baylor University MedicalResearch.com: What is the background for this study? What are the main findings? Response: There’s a fairly sizable literature suggesting that religious affiliation and religious engagement are associated with positive health outcomes. Therefore, we were surprised to find that agnostic/atheist individuals reported better sleep health than Christian individuals in the Baylor Religion Survey (BRS-5). 73% of agnostic/atheist individuals reported sleeping 7-9 hours/night whereas only 63% of Christian individuals met these consensus sleep guidelines. The most affected Christian denominations were Baptists (54.6%) and Catholics (62.3%). These results stood even after adjusting for age and gender. We predicted the opposite pattern. And, it wasn’t just about longer sleep durations. Agnostic/atheist individuals even reported greater ease falling asleep compared to Christian individuals.    (more…)

MedicalResearch.com Interview with: Benjamin Glicksberg, PhD Assistant Professor of Genetics and Genomic Sciences Member of the Mount Sinai COVID Informatics Center Member of the Hasso Plattner Institute for Digital Healt Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? Response: Reports from health systems that detailed the clinical characteristics and outcomes of their COVID-19 patients were instrumental in helping other health systems rapidly adapt and know what to expect. There are few studies, however, that assess what happens to these patients after they were discharged from the hospital. In our work, we address this gap by determining both how many individuals re-present to the hospital within 14 days, and what clinical characteristics of these patients differ from those who do not. Such information is critical in order to continue to refine optimal treatment plans and discharge decisions for patients of all backgrounds and clinical profiles. To provide more context to the question, we also determined if and how these factors changed between initial presentation and readmission to the hospital. (more…)

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.     (more…)
Author Interviews, ESMO, Immunotherapy, Melanoma, NEJM / 03.09.2020

MedicalResearch.com Interview with: Reinhard Dummer, Prof. Dr. med. Stv. Klinikdirektor Universitätsspital Zürich, Dermatologische Klinik Zürich MedicalResearch.com: What is the background for this study? Response: Based on molecular biology analysis, a substantial proportion of melanomas are driven by mutations of BRAF resulting in an ongoing growth activating signal. Based on the key role of BRAF several multiple kinase molecules have been developed in order to target this crucial pathway. These medications have shown to improve progression free survival and overall survival in advanced metastatic melanoma. Because there is a tendency for improved outcome in patients with low tumor burden, combined targeted therapy using Dabrafenib and Trametinib have been investigated in the adjuvant (after complete surgical resection) setting in stage III melanoma. And the 5 year data are now available in the New England Journal of Medicine. (more…)

MedicalResearch.com Interview with: Edmund K Bartlett, M.D. Department of Surgery/Division of Surgical Oncology Memorial Sloan Kettering Cancer Center New York, New York   MedicalResearch.com: What is the background for this study? Response: Indications for adjuvant therapy for resected, high-risk melanoma is a controversial and rapidly-evolving topic in melanoma treatment. Immunotherapy treatments targeting PD-1 have significantly improved survival in advanced-stage disease, but the magnitude of survival benefit in stage III disease--particularly stage IIIA--remains unclear. Recently, 31-GEP (a gene expression profiling assay) has been studied as a risk-stratifying tool to identify patients who are at higher risk for systemic recurrence. Ideally such a tool could identify patients most likely to benefit from immunotherapy treatment in the adjuvant setting (when all visible disease has been removed). (more…)

MedicalResearch.com Interview with: Sarabeth Spitzer, MD Co-Chair of Board, Scrubs Addressing the Firearm Epidemic (SAFE) Department of Surgery, Brigham and Women’s Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Firearm injury is a significant cause of morbidity and mortality in the United States, resulting in almost 40,000 deaths annually in the United States, but very little is known about the epidemiology of nonfatal firearm injuries. Nonfatal firearm injuries can have significant long-term morbidity and are associated with significant cost. We found that there were over 81,000 nonfatal firearm injuries in California over the study period. Over the period, there was a decrease in nonfatal firearm injuries by 38.1%, driven primarily by a decrease in assault injuries.   (more…)

MedicalResearch.com Interview with: Jessica Shoaff, MPH, PhD Postdoctoral Research Fellow and Susan A. Korrick, MD Pulmonary and Critical Care Assistant Professor in the Department of Environmental Health Harvard Medical School · Harvard T. H. Chan School of Public Health Brigham and Women's Hospital Channing Laboratory Boston, MA 02115   MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our study posed the question:  Do teenagers’ exposures to chemicals that are often found in consumer products increase behaviors that are common among individuals diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD)? Our results suggest that teenagers exposed to chemicals often found in consumer products (particularly phthalates) may have increased behaviors that are common among individuals diagnosed with ADHD.  However, we did not study the diagnosis of ADHD (most of our study teens did not have ADHD).  This means our results cannot answer the question of whether these chemical exposures increase the likelihood of being diagnosed with ADHD. Also, in our study design, chemical exposures and ADHD-related behaviors were measured at the same time, so it is not possible to know with certainty whether the chemical exposures altered behavior or behavior altered chemical exposures.  (more…)

MedicalResearch.com Interview with: Elena B. Hawryluk, MD, PhD Board-certified Dermatologist and Pediatric Dermatologist Assistant Professor of Dermatology Harvard Medical School Faculty Director of Pediatric Dermatology Harvard Combined Dermatology Residency Program. Dr. Hawryluk sees patients at Massachusetts General Hospital and Boston Children’s Hospital, and has a clinical interest in pigmented lesions and melanoma in the pediatric population. Dr. Hawryluk is a member of the Society for Pediatric Dermatology. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Melanoma is exceptionally rare and challenging to diagnose in the pediatric population.  The most important and clearly defined patients with melanoma are those with an aggressive fatal course, so this study was pursued to evaluate fatal presentations to help physicians to recognize those patients at highest risk.  Due to the rarity of fatal pediatric melanoma, in order to study a big enough group, our research team included pediatric dermatologists who collaborated from major institutions across the US and Canada, through the Pediatric Dermatology Research Alliance (PeDRA).  (more…)

MedicalResearch.com Interview with: Melissa A. Simon, M.D., M.P.H. George H. Gardner Professor of Clinical Gynecology Vice Chair of Clinical Research Department of Obstetrics and Gynecology Professor of Preventive Medicine and Medical Social Sciences Northwestern University Feinberg School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Sexually transmitted infections (STIs) are on the rise across the country, with approximately 20 million new cases in the U.S. each year. If untreated, STIs can lead to serious health complications including infertility, AIDS, and cancer. The good news is that effective behavioral counseling has the potential to reduce STI rates by approximately a third. The Task Force continues to recommend behavioral counseling for all sexually active teens and for adults who are at increased risk for STIs.

MedicalResearch.com Interview with: Robert Fisher, MD, PhD Professor of Oncological Sciences Icahn School of Medicine at Mount Sinai Member of The Tisch Cancer Institute MedicalResearch.com: What is the background for this study? Response: Gene transcription by RNA polymerase II underlies cellular identity, and cell fate decisions such as proliferation or death, and is regulated by enzymes that add phosphates (kinases) or remove them (phosphatases) from components of the transcription machinery. Here we define two kinase-phosphatase switches that regulate different steps of the transcription cycle in human cancer cells.  We raised antibodies specific for different phosphorylated states of a key elongation factor, Spt5, and used genomic analyses such as chromatin immunoprecipitation and sequencing (ChIP-seq) to monitor when these phosphorylations were added and removed, and by which kinases and phosphatases, respectively, as RNA polymerase II traversed genes in human cancer cells.

Author Interviews, Geriatrics, Hearing Loss, JAMA / 28.08.2020

MedicalResearch.com Interview with: Cameron C. Wick, MD Assistant Professor, Otology/Neurotology Washington University School of Medicine St. Louis, MO MedicalResearch.com: What do you see as the primary message of your findings for the general public? Response:  Older adults not satisfied with their hearing aids achieved clinically meaningful improvement in both hearing and quality of life with a cochlear implant compared to an optimized bilateral hearing aid condition. MedicalResearch.com: Do you see your findings as changing the way older adults with hearing loss are managed? Response:   Yes and partially because this study is unique in its design and the outcomes that were measured. Specifically  the study is a prospective, multicenter clinical trial conducted at 13 locations across the United States. All patients were setup with a 30-day optimized hearing aid experience before cochlear implantation (context: sometimes hearing aids are not appropriately optimized so baseline testing may not reflect the "best" that hearing aids can do). This study assesses both hearing data as well as quality of life data before and 6-months after cochlear implantation. After implantation patients were tested in both the unilateral (cochlear implant alone) and bimodal (cochlear implant plus hearing aid in the opposite ear) conditions.  My paper is a subanalysis of adults 65 years and older (range 65 - 91 years) enrolled in the clinical trial. The principal investigator of the clinical trial is Dr. Craig Buchman. Dr. Buchman and myself are at Washington University in St. Louis which was the lead center for the clinical trial. The findings of the study are meaningful because they demonstrate clear superiority of cochlear implants over hearing aids in many key areas, such as understanding speech, hearing in background noise, and ability to communicate. Hearing loss, which becomes more prevalent as we age, can negatively impact communication leading to social isolation, depression, frustration, and possibly cognitive decline. This study highlights that if patients are not satisfied with their hearing aid performance then they should be referred to a center that can evaluate for cochlear implantation. Cochlear implant indications have evolved considerably since they were first FDA approved in 1984. This study emphasizes that patients do not have to be profoundly deaf to experience significant hearing and social benefits from cochlear implants. Also, it demonstrates that cochlear implant surgery is well tolerated even as adults age and acquire other health ailments.  (more…)
