MedicalResearch.com Interview with: [caption id="attachment_55407" align="alignleft" width="200"]Rong Xu PhD Center for Artificial Intelligence in Drug Discovery, School of Medicine Case Western Reserve University Cleveland, OH Dr. Rong Xu[/caption] Rong Xu PhD Center for Artificial Intelligence in Drug Discovery, School of Medicine Case Western Reserve University Cleveland, OH MedicalResearch.com: What is the background for this study? What are the main findings? Response: Chronic use of tobacco, alcohol and other drugs is associated with cardiovascular, pulmonary, and metabolic diseases, all of which are also risk factors for COVID-19 infection and for worse outcomes.  Additionally, individuals with substance use disorders are more likely to experience social adversity such as homelessness, decreased access to health care, housing insecurity among others. Based on these, we hypothesis or predict that individuals with SUD are especially vulnerable for COVID-19 infection and adverse outcomes. In our study, we found that  individuals with substance use disorders, especially individuals with OUD and African Americans with SUD, as having increased risk for COVID-19 and its adverse outcomes

MedicalResearch.com Interview with: [caption id="attachment_55390" align="alignleft" width="200"]Irfan Rahman, Ph.D. Principal Investigator. Center for Inhalation and Flavoring Toxicological Research University of Rochester Dr. Rahman[/caption] Irfan Rahman, Ph.D. Principal Investigator. Center for Inhalation and Flavoring Toxicological Research University of Rochester MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our study aimed to determine whether vaping and smoking affect Covid-19 proteins and genes and whether that effect changes depending on the age of the vaper/smoker. SARS-Cov-2, the virus that causes Covid-19, enters cells by interacting with ACE2 and TMPRSS2-Furin proteins. We found that both of these proteins increase with age and are also increased by smoking or vaping. This suggests that older adults, smokers and vapers may be more prone to infection with SARS-Cov-2 and may be more likely to have severe complications.

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.

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.

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)

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.

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: That at peak times of COVID in NJ, in a tertiary care hospital with lots of COVID patients, where cancer patients still need to get treated, there was no evidence of surface COVID contamination, which should be reassuring to patients requiring radiation treatment in a busy hospital with a high in patient population of COVID patients. It should be noted that patients and staff were routinely mask wearing, observing social distancing and routinely hand washing as well as screening patients as they came in to the department with temperature checks and questions regarding symptoms.

Would you explain what is meant by cytokine/cytokines? Response: COVID-19 is a disease where inflammation is suspected to play a large role in pathogenicity, possibly more so than the tissue damage created by the virus alone. Cytokines are small soluble proteins that are produced by both immune cells and cells from tissues, and many play a role in signaling such inflammation, to alert of tissue damage or infection. Among these cytokines, interleukin-6 (IL-6), IL-8, IL-1beta, and Tumor Necrosis Factor alpha (TNF-a) have been well established as important markers of pathogenic inflammation. Drugs that counteract these cytokines are routinely use in various inflammatory disease, from rheumatoid arthritis to plaque psoriasis and Crohn’s disease. When the initial wave of SARS-CoV-2 infection hit our hospitals in New York, we therefore wondered whether these cytokines were associated with COVID-19 disease severity and outcome, and hoped that a rapid test to detect them in blood could be useful to make clinical decisions about treatment. We were able to analyze a very large number of patient samples (>1400) in a period of one month, and confirmed our findings in a second smaller cohort.

Trindade, MD Director of Endoscopy Long Island Jewish Medical Center Associate professor at Feinstein Institutes for Medical Research Division of Gastroenterology, Zucker School of Medicine Hofstra/Northwell, Northwell Health System New Hyde Park, NY MedicalResearch.com: What is the background for this study? Response: Although most patients with COVID-19 present with respiratory symptoms, gastrointestinal (GI) symptoms have also been reported in up to 25% of patients. Some case reports have shown acute pancreatitis as the initial presentation in patients with COVID-19, however the literature supporting this is limited. Our study aimed to report the point prevalence, risk factors, and outcomes of hospitalized patients with COVID-19 presenting with acute pancreatitis in a large health system and to compare outcomes of pancreatitis in patients without COVID-19.

What are the main findings? Response: This exploratory research uses the currently available data on COVID-19 cases and mortality, along with estimates of the morbidly obese populations in the United States by county to examine the association between morbid obesity and deaths from COVID-19 and to identify potential coincident spatial clusters of morbid obesity and COVID-19 deaths. Results indicate statistically significant positive correlation between population adjusted COVID-19 deaths and cases and the estimated population with a BMI>=40. Clustering analyses show there is a predominant similarity in the distribution of COVID-19 deaths and obesity. Our findings suggest it is critical to include an awareness of obesity when developing infectious disease control measures and point to a greater need to focus resources towards obesity education and policy initiatives.

MedicalResearch.com Interview with: Dr. Ajit Ahlawat (en.) Scientific staff (Post-Doc), Department Experimental Aerosol & Cloud Microphysics Leibniz Institute for Tropospheric Research (TROPOS) MedicalResearch.com: What is the background for this study?   Response: World Health Organization (WHO) has recently acknowledged that novel coronavirus (COVID-19) can be transmitted via aerosols after an appeal from 239 scientists from 32 countries including the chemist Prof. Hartmut Herrmann from our institute i.e. TROPOS. In order to contain the spread via the aerosol particles floating in the air, the researchers recommend not only continuing to wear masks but also, and above all, good indoor ventilation. In aerosol research, it has been long known that air humidity plays a major role i.e. either at high humidity, more water adheres to the particles and so they can grow faster or at low humidity, evaporation occurs and particle will lose its water content. So, we were curious about what types of studies have already been conducted on this topic and how indoor relative humidity (RH) will influence SARS-CoV-2 airborne transmission in indoor environments.

Here, we show that children can become sick from SARS-CoV-2 infection, and even if the initial illness is mild, some go on to develop a severe inflammatory illness after the initial illness. We also show that children can carry very high levels of virus early in the course of infection, suggesting they may play a larger role in spreading the virus than previously thought.

Response: We wanted to get a comprehensive picture of the epidemiology of COVID-19 in carceral facilities that included jails and was not restricted solely to prisons. We utilized publicly available data collected in Massachusetts, pursuant to a court order. These data included prison and jail systems and were used to calculate rates of confirmed cases of COVID-19 and testing rates among incarcerated individuals. We were also able to compare those to changes in the population size within each system.

What are the main findings? Response: We sought to compare the initial covid-19 outbreak in NYC to the peak of the 1918 H1N1 pandemic in that same city. We found that the covid-19 pandemic was associated with more than 70% as many deaths per capita (monthly) as 1918 H1N1 was. But because baseline mortality rates are about 1/2 of what they were a century ago, death rates were over 400% of usual rates in March and April of this year compared to recent years, while 1918 was "merely" over 280% of usual death rates from prior years leading up to it.

Response: Several studies have highlighted disparities in COVID-19 infection rates and deaths. Less is known about disparities in hospitalizations. Reports from the Centers for Disease Control showed that in the nation overall, non-Hispanic Blacks, Hispanics and American Indian Alaska Native persons have substantially higher rates of COVID-19 hospitalization. Our study extends this work by providing a state-by-state analysis of race/ethnic prevalence of cumulative COVID-19 hospitalizations and comparing this prevalence to ethnic/racial composition of each state’s population. Through our University of Minnesota Covid-19 hospitalization tracking project (https://carlsonschool.umn.edu/mili-misrc-covid19-tracking-project) we collect data every day from state department of health websites, and we started collecting information on race/ethnicity breakdown of the hospitalizations as soon as states started reporting such data. During our study period, between April 30 and June 24, 12 states reported cumulative hospitalizations by race/ethnicity. By the end of our study, our data from these 12 states represented almost 50,000 hospitalizations.

What are the main findings?  Response: Antiphospholipid Syndrome is an entity caused by autoantibodies that cause arterial and venous thrombosis as well as miscarriages. During the COVID-19 pandemic, we tested 187 patients for Lupus anticoagulant (LA); 68 turned out to be COVID positive. 30 of the 68 COVID-positive patients were found to be positive for LA by the DRVVT test, and 17 of them were also determined to be positive by the hexagonal phospholipid neutralization STACLOT-LA test. Importantly, of the 30 patients who were LA positive, 19 had documented thrombosis (arterial and venous), an event rate of 63%, as compared with a rate of 34% (p = .03) for LA-negative patients. We also checked CRP, an inflammatory marker known to affect the hexagonal phospholipid neutralization STACLOT-LA test. Although the mean CRP level was higher in patients testing positive for LA by DRVVT (14.4 vs 7.5 mg/dL; P < .01), patients with thrombosis did not have significantly higher CRP levels than those with no thrombosis. Hence, we adjusted for CRP, and LA was found to be independently associated with thrombosis (odds ratio, 4.39; 95% CI, 1.45-14.57; p= .01). No statistically significant difference was found by anticoagulation at the time of thrombosis, gender, race, ethnicity, ventilation, and mortality between patients who tested LA positive vs. negative.

MedicalResearch.com Interview with: Dr. Amy KennedyDr. Amy Kennedy, M.D., M.S Clinician-Researcher Fellow, General Internal Medicine University of Pittsburgh  MedicalResearch.com: What is the background for this study? Response: UPMC uses a nucleic acid polymerase chain reaction (PCR) test for SARS-CoV-2 and specimen collection is done with a nasopharyngeal swab by trained clinicians. The health system developed its COVID-19 test in early March 2020 in anticipation of the tremendous need for diagnostic capabilities. My colleagues and I worked with the Wolff Center at UPMC — the health system’s quality care and improvement center — to review the results of more than 30,000 COVID-19 tests performed on adult patients who received care through one of UPMC’s 40 academic, community and specialty hospitals, or 700 doctors’ offices and outpatient sites in Pennsylvania, New York and Maryland. The tests were performed between March 3 and May 3, 2020. Of those tests, 485 were repeated at least once.

What are the main findings? Response: New York was epicenter for COVID-19 at the height of the pandemic, and Northwell Health, the largest health system in New York, did everything in its power to care for our sick community members but also care for and protect our frontline health care providers (HCPs) and 72,000 employees. We were fortunate enough to have not run out of PPE – from masks to gowns. Through our employee health team we were able to offer free antibody screenings and through the Northwell Health Research Consortium and the Feinstein Institutes for Medical Research we looked to use the data collected from our consented employees to determine the prevalence of antibodies. We designed the study to not only identify the presence of antibodies but also key factors like demographics, in what capacity our providers worked on the frontlines and if they suspected infection. Our data helped identify the best practices Northwell Health – from PPE to care procedures - and others nationwide would need to do to keep our frontline workers safe. Key takeaways from the research show that from April 20 to June 23, of the final consented sample of health care providers (40,329), 13 percent (5,523) tested positive for antibodies. The positive sample pool included 28.4 percent (11,468) nurses and 9.3 percent (3,746) physicians.

Response: The accurate diagnosis of COVID-19 is critical for our patients in order to receive appropriate care, and for infection control and public health. In the US, the gold standard for COVID diagnosis is sampling through a nasopharyngeal swab (NP)  but is that really the best way to diagnose COVID?  As many of your viewers may have experienced first hand, nasopharyngeal swabs require inserting a long swab into the back of the nose, which is incredibly uncomfortable for the patient, technically-challenging for the health care worker, and requires equipment and reagents that are in short supply. There are also alternative sampling methods for COVID diagnosis. In Asia, oropharyngeal sampling(OP), or swabbing the back of the mouth, are commonly used and in my hospital, the Brigham and Women’s Hospital, we frequently test sputum as well for inpatients.  But there’s a lot of confusion in the field about which of these methods is the most sensitive? We undertook this study to try to bring some clarity to this question of what is the most sensitive way to diagnose COVID and detect SARS-CoV-2?

Response: We wanted to develop a test that would be: 1) Reliable and fast to perform, 2) Easy and fast to manufacture, 3) Easy and fast to distribute and be adopted by the Health care community. We also wanted to capitalize on our vast expertise and experience from developing novel blood typing tests. Our strategy was to develop a serology COVID test using the current Gel card technology available in most hospital and blood laboratories throughout the world. Equipment and expertise are already available from point of care setting to high throughput/automated systems measuring 100-200 test/ h. Also, these cards are currently produced by many companies all over and these can be shipped all international.

MedicalResearch.com Interview with: [caption id="attachment_54883" align="alignleft" width="155"]Abdi Ghaffari, Ph.D. Associate Professor (adjunct) Dept. of Pathology and Molecular Medicine Queen’s University Dr. Ghaffari[/caption] Abdi Ghaffari, Ph.D. Associate Professor (adjunct) Dept. of Pathology and Molecular Medicine Queen’s University MedicalResearch.com: What is the background for this study? Response: SARS-CoV-2 virus has infected millions and changed our way of life by placing nearly 3 billion people under lockdown or some form of physical isolation. In the absence of a vaccine or reliable treatment, diagnostic testing must be a pillar of public health policy to control further spread of the virus and to guide gradual removal of lockdown measures. COVID-19 antibody diagnostic tests are being increasingly used to assess the protective immunity status in the population. There are over 100 different COVID-19 antibody tests developed by companies worldwide in an effort to address this need. However, companies’ reported performance data are not always in line with the actual performance of these diagnostic tests in the real-world. In this work, we conducted a systemic review of independent studies (sponsored by academic or government institutions) that aimed to validate the performance of currently available COVID-19 antibody tests on the market.
