MedicalResearch.com Interview with: Xing Gao, MPH, lead author and doctoral candidate in Dr. Mujahid's research group Mahasin Mujahid, MS, PhD, FAHA Lillian E. I. and Dudley J. Aldous Chair in the School of Public Health Associate Professor of Epidemiology Director, Epidemiology & Biostatistics Master of Public Health Program UC Berkeley, School of Public Health MedicalResearch.com:  What is the background for this study?  What are the main findings?
  • ​​Hypertension is a major risk factor for cardiovascular diseases, and persistent racial and ethnic inequities in hypertension remain an urgent public health challenge.
  • Public health researchers need a more nuanced understanding of how structural factors contribute to these inequities, which has a direct application to improving the cardiovascular health of marginalized populations.
  • This study examined associations between racial residential segregation, a product of historical and contemporary racially discriminatory policies, and hypertension in a multi-racial cohort of middle-aged and older adults.

This is important because when child care programs close it becomes very difficult for working families to find safe, affordable alternative care. We surveyed over 6000 child care workers from across the US in May/June 2020 with a follow up survey in May/June 2021. This includes both center based and home based child care programs. One question we were interested in was what things they were doing in their programs to reduce the risk of COVID-19. We then asked whether their program closed at any time in that year because of COVID-19.

For this recommendation, the Task Force evaluated whether screening adults over the age of 50 who do not have any signs or symptoms of AFib can help prevent strokes. In its evidence review, Task Force expanded its scope to include a search for studies on portable and wearable devices such as smartphones and fitness trackers in addition to electrocardiography (ECG). Despite this consideration, the Task Force found insufficient evidence to recommend for or against screening for AFib. This is consistent with the Task Force’s 2018 recommendation.

Response: The COMPILE study is based on real-time collection of individual patient data from 8 international completed, terminated early and ongoing randomized clinical trials testing the efficacy of convalescent plasma for the treatment of hospitalized patients with COVID-19. Recruitment covered the period from March 2020 to March 2021 in Asia, Europe, North and South America. Total of 2369 patients were enrolled and data from 2341 patients were used in the analysis. COMPILE, the largest study of convalescent plasma for hospitalized COVID-19 patients to date, provided robust information on a diverse patient population, which allowed rigorous evaluation of questions related to convalescent plasma efficacy. The main findings are that convalescent plasma might have only a moderate efficacy on average, but that there is a huge heterogeneity in the benefits for individual patients.

Existing research often categorize Asian Americans into a single racial category, which may mask differences in health behaviors and outcomes subgroups. We sought to examine potential differences in skin cancer-related risk factors and screening among Asian Americans in a large, nationally representative study.

Although there has been a lot of discussion about vaccine hesitancy as a barrier to achieving high rates of COVID-19 vaccination, there have been few studies of changes in hesitancy - or how it might vary across groups. As COVID-19 vaccines were becoming available in the US there was a lot of discussion about worrisome rates of vaccine hesitancy, particularly among communities of color. Our team suspected, however, that these high rates might be short-lived, and that Black Americans in particular might become willing to use COVID-19 vaccines after a short period of time - as they became reassured that they would be safe, effective, and protect communities.

Response: More than 192 million people ages 12 years and older in the U.S. received at least one dose of mRNA COVID-19 vaccines from December 2020 through August 2021. From this population, VAERS (the Vaccine Adverse Event Reporting System) received 1,991 reports of myocarditis,  1,626 of which met the case definition of myocarditis. Rates of myocarditis were highest following the second dose of an mRNA vaccine among males aged 12–15 years (70.7 per million doses of Pfizer), 16-17 years (105.9 per million doses of Pfizer), and 18–47 years (52.4 and 56.3 per million doses of Pfizer and Moderna, respectively). Of those with myocarditis, the median age was 21 years and the median time from vaccination to symptom onset was two days. Males accounted for 82% of patients for whom sex was known. Approximately 96% were hospitalized, 87% of whose symptoms had gone away by the time they were discharged from the hospital. Non-steroidal anti-inflammatory drugs (589/676, 87%) were the most common treatment.

[caption id="attachment_58695" align="alignleft" width="150"]Stephen Connelly, PhD, Chief Scientific Officer, Equillium Dr. Connelly[/caption] Stephen Connelly, PhD Co-founder & Chief Scientific Officer Equillium, Inc. San Diego, California MedicalResearch.com:  What is the background for this study?    Response: Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease that predominantly affects women in the reproductive age range. Approximately 50% of SLE patients experience lupus nephritis (LN), a serious complication that is accompanied by significant morbidity and mortality. Progression of LN to chronic kidney disease is common, with 10% of patients with LN developing end-stage kidney disease. T cells, play a central role in the pathogenesis of both SLE and LN by mediating tissue damage and enhancing the production of autoantibodies by promoting B cell differentiation, proliferation, and maturation. These T cells express CD6, a costimulatory receptor that through its binding to activated leukocyte cell adhesion molecule (ALCAM), expressed on immune cells and tissues, modulates both the activity and trafficking of effector T cells (Teff). The expression of both CD6 and ALCAM (CD6-ALCAM pathway) have been associated with pathogenic effector T cell activity and trafficking in multiple autoimmune and inflammatory diseases. Based on a comprehensive screen of more than 1100 urine proteins, soluble urinary ALCAM (uALCAM) was identified as one of only a few molecules that were elevated in the urine of patients with SLE with active renal involvement compared with patients with quiescent or no prior nephritis. However, no studies had been conducted to characterize the cellular sources of the soluble ALCAM and questions remained about the relevance of this protein and whether it was associated with the pathology of the disease.

Social isolation is the lack of social contacts and having few people to have regular interactions; while loneliness is the distressing feeling of being alone or separated. Approximately 24% of community-dwelling older adults aged 65 and above are considered to be socially isolated in the United States, and 43% adults aged over 60 years old report feeling lonely. Increasing evidence suggests that social isolation and loneliness are risk factors for older adults’ health outcomes, such as depression, comorbidities, cognitive impairment and dementia, and premature mortality. However, one key limitation in the literature is that only a few studies have examined the impact of social isolation and loneliness on oral health.

Response: Fixation with metal implants provides reliable functional outcomes for patients after a manipulation of a displaced fracture of the distal radius, but such surgery carries risk for the patient and is expensive. A moulded plaster cast is a safer and cheaper intervention but may not provide the same functional outcome. It is not known which of these treatments is superior.

MedicalResearch.com Interview with: [caption id="attachment_58667" align="alignleft" width="200"]Dr Julia Ware (née Fuchs) Clinical Research Associate Wellcome-MRC Institute of Metabolic Science-Metabolic Research Laboratories  and Medical Research Council Metabolic Diseases Unit, University of Cambridge Addenbrooke’s Hospital, Cambridge  Dr. Ware[/caption] Dr Julia Ware (née Fuchs) Clinical Research Associate Wellcome-MRC Institute of Metabolic Science-Metabolic Research Laboratories and Medical Research Council Metabolic Diseases Unit, University of Cambridge Addenbrooke’s Hospital, Cambridge MedicalResearch.com: What is the background for this study? Response: Management of type 1 diabetes is challenging in very young children, due to their high variability of insulin requirements and unpredictable eating and activity patterns. As a result, many young children do not meet the recommended glycemic targets, or only maintain recommended glycemic control with extensive caregiver input. This in turn leads to high management burden and reduced quality of life for the whole family. While the increasing use of continuous glucose-monitoring devices and insulin-pump therapy has led to reductions in the incidence of severe hypoglycaemia and diabetic ketoacidosis, and has been accompanied by modest improvements in glycemic control, the burden of management has remained high. Hybrid closed-loop systems (also called an artificial pancreas), in which an algorithm automatically adjusts insulin delivery on the basis of real-time sensor glucose levels, may address ongoing challenges in this age group. However, to date hybrid closed-loop studies involving very young children have been small and of short duration and the efficacy and safety of longer term use of a closed-loop system, as compared with standard therapy, was unclear.   To address this knowledge gap, we compared 16-week use of the Cambridge closed-loop algorithm with sensor-augmented pump therapy in children aged 1 to 7 years with type 1 diabetes in a multi-national randomised crossover study.

This affords the opportunity to analyse ‘historical’ cohorts covering a period of important socio-demographic, economic, and educational change in the UK from which current and emerging trends may be identified and examined. Drawing on our previous proof-of-concept study, we investigated whether there were differences between childhood-onset versus adult-onset myopia in temporal trends in both frequency and severity and in associations with key environmental factors.

MedicalResearch.com Interview with: [caption id="attachment_58674" align="alignleft" width="150"]Marcus Koch Dr. Koch[/caption] Marcus Koch MD PhD Associate Professor of Neurology Multiple Sclerosis Program University of Calgary MedicalResearch.com: What is the background for this study? Response: Primary progressive multiple sclerosis (PPMS) is the least common, but also the least treatable form of multiple sclerosis. PPMS does not react well to commonly used MS treatments. We believe that this is at least in part because PPMS is driven by other disease mechanisms. One disease mechanism that we believe is important in PPMS is microglial activation. Microglial cells are a type of cell in the brain and spinal cord that normally have beneficial functions, such as clearing debris or assisting repair after injury. In PPMS however, microglial cells are chronically active, and we believe that this chronic microglial activation contributes to tissue damage.

Carver College of Medicine University of Iowa Dr. Bell[/caption] Edward Bell, MD Professor of Pediatrics-Neonatology Vice Chair for Faculty Development, Stead Family Department of Pediatrics Roy J. and Lucille A. Carver College of Medicine University of Iowa MedicalResearch.com: What is the background for this study? Response: The National Institute of Child Health and Human Development, a branch of the National Institutes of Health (NIH), has supported the Neonatal Research Network (NRN) since 1986. The NRN, a group of US academic centers, is tasked with conducting research to improve the treatment and health outcomes of premature and critically-ill babies in US neonatal intensive care units (NICUs). Every few years, the NRN publishes reports on the survival rates and outcomes of surviving extremely premature babies, those born before 28 weeks of gestation. These reports help us to judge progress in the care and outcomes of these infants. This paper is the 9th in this series of reports but the first that includes not only survival and in-hospital outcomes but also outcomes at 2 years of age.

MedicalResearch.com Interview with: Laura Rupprecht, PhD Postdoctoral Fellow Kelly L Buchanan The Laboratory of Gut Brain Neurobiology Duke Medicine – GI Diego V. Bohórquez PhD Associate Professor in Medicine Duke Institute for Brain Sciences Durham, NC MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: In 2018, my laboratory discovered that a cell type in the gut epithelium synapses with the vagus nerve, the nerve which connects the gut and the brain. These gut cells are called neuropod cells. Neuropod cells transduce sugar within milliseconds using the neurotransmitter glutamate. Since then, we have been interested in defining how this rapid communication between neuropod cells and the brain regulates behavior. – Diego Bohórquez Over a decade ago, it was shown that the gut is the key site for discerning sugar and non-caloric sweetener. But the specific cell in the gut that underlies this effect was unknown. – Kelly Buchanan

MedicalResearch.com Interview with: Kassandra L. Munger Sc.D. Senior Research Scientist Alberto Ascherio MD Dr.P.H. Professor of Epidemiology and Nutrition Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? Response: An infectious cause of MS has been hypothesized for decades. Research over the past 20 years conducted by our group and others has strongly suggested a role for EBV infection including that EBV-negative individuals have a near zero risk of developing MS, having a history of infectious mononucleosis (caused by EBV infection) increases the risk of MS 2-fold, and healthy individuals have higher risks of MS with higher antibody levels against EBV antigens.  Ideally, to prove causality a randomized clinical controlled trial would be conducted; however, this not a feasible approach in this case. Given that nearly 95% of the adult population is infected with EBV and MS is a rare disease, we utilized the Department of Defense Serum Repository which stores over 60 million serum samples from over 10 million US Military active duty personnel. From this large resource, we were able to identify a cohort who were EBV negative when they joined the military and we followed them for whether they had a primary infection with EBV and then for who developed MS.

Bundy, PhD, MPH Department of Epidemiology Tulane University School of Public Health and Tropical Medicine and Tulane University Translational Science Institute New Orleans Louisiana MedicalResearch.com: What is the background for this study? What is included in the KFRE score? Response: Kidney function is quantified using estimated glomerular filtration rate (eGFR), which is often calculated in clinical practice using filtration markers like serum creatinine and/or cystatin C, and patient characteristics like age, sex, and race. Recently, new eGFR equations were created that remove race adjustment because of concerns that using a patient’s race may perpetuate racial inequities in healthcare delivery. The Kidney Failure Risk Equation (KFRE) is the most commonly-used tool to predict end-stage kidney disease (ESKD) risk and includes age, sex, eGFR, and urinary albumin-creatinine ratio. We sought to evaluate the impact of removing race from eGFR on prediction of ESKD.

Assistant Professor of Epidemiology (Environmental Health Sciences) Assistant Professor in Chemical and Environmental Engineering Affiliated Faculty, Yale Institute for Global Health Yale School of Public Health  MedicalResearch.com: What is the background for this study? Response: People infected with COVID-19 can release SARS-CoV-2 virus in aerosol and droplets when they exhale. This can be from coughing or sneezing but also when they speaker or just breathe. While the larger droplets can settle to the ground quickly (seconds to minutes), smaller aerosol can remain in the air in longer periods (minutes to hours). SARS-CoV-2 can be transmitted by inhaling aerosol or droplets containing infectious virus. The Fresh Air Clip enables detection of droplet and aerosol containing virus.

Response: Mortality among people with diabetes, and how it changes over time, is an important indicator of quality of and access to health care. However, population level trends in mortality among people with diabetes are inadequately described. The establishment of national diabetes registers, health insurance data and administrative data has allowed the examination of mortality among those with diabetes at a granular level which has been previously not possible. This has allowed us to examine whether global efforts in regards to diabetes care over the last couple of decades have been effective.

Where is triclosan commonly found? Response: Triclosan is a commonly found antibacterial compound present in hand soaps, toothpastes, athletic clothes, and children’s toys. A previous study by the Zhang group (corresponding author on this publication) found that antimicrobial compounds including triclosan increased inflammation (similar to that of inflammatory bowel disease (IBD)) and tumor formation in the colon. These effects were observed only in mice with an intact gut microbiome, not in germ-free mice which lack a gut microbiome, suggesting that the gut microbiome is somehow responsible for the toxicity of triclosan to the gut. Our study investigates how gut bacteria promote triclosan toxicity in the gut

Response: During the early stages of the global 2019 coronavirus disease (COVID-19) pandemic, children represented fewer than 5% of reported cases.  However, children now represent a significant percent of all new COVID-19 cases.  Similarly, pediatric hospitalizations due to COVID-19, are now at an all-time high.  Although COVID-19 is generally mild in children, severe outcomes and death do occur.  The risk of severe outcomes among SARS-CoV-2 infected children is poorly understood with estimates varying considerably between study designs, settings, and regions.  Studies generally include large administrative databases (i.e. community based), hospitalized populations, and children admitted to the intensive care unit (ICU). Identified risk factors for severe COVID-19 in children have included young (i.e. 1-3 months) or old (15-18 years) pediatric age group, male sex, and pre-existing medical condition.  However, data from large prospective cohort studies which include children with early or mild stages of disease seeking emergency department (ED) care are lacking. To address this knowledge gap we sought to quantify the frequency of and risk factors for severe outcomes in SARS-CoV-2 infected children enrolled in a prospective ED-based cohort study.

Response: The prescription stimulants methylphenidate, amphetamine, and lisdexamfetamine, classified as Schedule II substances, are sympathomimetic drugs with therapeutic use widely used in the US for Attention Deficit Hyperactivity Disorder. Changes in criteria for diagnosis of Attention Deficit Hyperactivity Disorder in 2013 and approval of lisdexamfetamine for binge eating disorder in 2015 may have impacted usage patterns. The goal of this study1 was to extend upon past research2 to compare the pharmacoepidemiology of these stimulants in the United States from 2010–2017, including consideration to variation within geographic regions, the Hispanic population, and the Medicaid population.

Response: Canada legalized recreational, or non-medical, cannabis in October 2018. Canada took phased approach to legalization initially only allowing flower-based cannabis products and oils and after one year permitting the sale of commercial cannabis edibles (e.g. THC containing candies, baked goods, and drinks). In this study we took advantage of this phased roll out of legal cannabis to understand the impact of legalization on cannabis exposures or poisonings in children aged 0-9 years and the contribution of different types of cannabis products to these events.

What are the main findings?  Response: A lot of research has focused on the effects of COVID-19 in various vulnerable populations, such as elderly individuals, immunocompromised patients, and individuals with severe comorbidities. However, one vulnerable population that has remained relatively understudied are the infants exposed to maternal COVID-19 disease during pregnancy. While early on in the pandemic we and other groups showed reassuring data on low risk of vertical transmission, meaning the passing of the virus from mother-to-infant is rare, this does not necessarily mean that these infants wouldn't experience long-term consequences related to the maternal infection through other means. We know from other viral illness that maternal illness, most commonly through the activation of her immune system, can lead to a cascade of events that affect fetal development. This is why a large number of physicians and researchers at Columbia University spearheaded the COVID-19 Mother Baby Outcomes (COMBO) Initiative -- to look at potential long-term health effects on both infants and mothers.

Response: Canada was the first country in the world to remove all supplemental restrictions on the dispensing and administration of mifepristone, making the drug available as a normal prescription. This meant that the abortion pill could be prescribed by any doctor or nurse practitioner, dispensed by any pharmacist, and taken by patients when, where and if they choose.

Response: There has been growing evidence of the benefits of fecal transplants in some medical conditions, like cancer, hypertension and obesity for several years. In fish, it’s been shown that their lifespan could be extended significantly after fecal transplant from young fish. When we found an impact on cognitive function in mice from a fecal transplant, we decided to research and isolate how that biological mechanism was implemented.

MedicalResearch.com Interview with: Ting Martin Ma, MD, PhD Resident Physician Amar U. Kishan, MD Assistant Professor, Department of Radiation Oncology Vice-Chair of Clinical and Translational Research Department of Radiation Oncology at UCLA MedicalResearch.com: What is the background for this study? Response: We know from epidemiologic studies that  Black men are more likely to be diagnosed with and die of prostate cancer than White men. Recent studies hinted that Black men had better oncological outcome (such as prostate cancer specific mortality and overall survival) responding to systemic therapy for advanced prostate cancer (e.g. cancer that has spread or metastasized to other parts of the body). The question we were trying to answer in this study is: is there a difference in outcomes between Black and White men with localized prostate cancer (cancer that has not spread) receiving definitive radiotherapy enrolled in clinical trials?
