Author Interviews, Environmental Risks, JAMA, OBGYNE, Pediatrics / 04.02.2022

MedicalResearch.com Interview with: Anders Hviid M.Sc.,Dr.Med.Sci. Head of Department (acting), Professor of Pharmacoepidemiology, Department of Epidemiology Research Statens Serum Institut MedicalResearch.com:  What is the background for this study?  Response: An unusually low number of extremely preterm births have been observed in some countries during the initial covid-19 lockdowns. We speculated that this could be because of fewer infections, reduced activity levels, less stress etc. These are also factors that change with the seasons, and we hypothesized that extremely preterm birth might be associated with seasonality.

Author Interviews, COVID -19 Coronavirus, JAMA, NYU / 03.02.2022

MedicalResearch.com Interview with: Andrea B. Troxel, ScD (she/her/hers) Professor and Director, Division of Biostatistics Department of Population Health NYU Grossman School of Medicine NYU Langone Health MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: This study represents an international collaboration across four continents and six countries, to pool information from studies in different patient populations to generate robust information about the possible benefits of convalescent plasma in treating COVID-19. Because the study was so large and the methods so rigorous, we were able to show that while CP doesn’t benefit all patients, it may have positive effects in certain subgroups. (more…)
Author Interviews, COVID -19 Coronavirus, JAMA, Pediatrics, Respiratory, Yale / 03.02.2022

MedicalResearch.com Interview with: Thomas Murray MD PhD Associate Professor, Yale School of Medicine Department of Pediatrics, Infectious Disease and Global Health Associate Medical Director, Infection Prevention Yale New Haven Children's Hospital MedicalResearch.com:  What is the background for this study?  Response: This study was performed by Yale- CARES (Children and Adults Research in Early Education Study Team) a multidisciplinary group of researchers that are interested in learning how the COVID-19 pandemic has impacted early child care programs in the US including the effects on both the children and those who care for them in this setting. 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. (more…)
Author Interviews, Heart Disease, JAMA, NYU, USPSTF / 02.02.2022

MedicalResearch.com Interview with: Gbenga Ogedegbe, MD, MPH Dr. Adolph & Margaret Berger Professor of Population Health Director, Division of Health & Behavior Director Center for Healthful Behavior Change Department of Population Health NYU Langone Health NYU School of Medicine Member of the U.S. Preventive Services Task Force MedicalResearch.com:  What is the background for this study?  What are the main findings?  Response: Atrial Fibrillation (AFib) is the most common type of irregular heartbeat and a major risk factor for stroke, and it often goes undetected. 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. (more…)

MedicalResearch.com Interview with: Eva Petkova, PhD Professor, NYU School of Medicine Department of Population Health Division of Biostatistics Department of Child and Adolescent Psychiatry, New York, NY 10016 Senior Scientist, Nathan Kline Institute of Psychiatric Research, Orangeburg, NY 10962 MedicalResearch.com:  What is the background for this study?  What are the main findings? 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. (more…)
Author Interviews, Dermatology, Emory, JAMA, Race/Ethnic Diversity / 27.01.2022

MedicalResearch.com Interview with: Howa Yeung, MD MScHe/him/his Assistant Professor of Dermatology Emory University School of Medicine Atlanta, GA 30322 MedicalResearch.com:  What is the background for this study?  Response: Asian Americans are the fastest growing racial group in the United States but are underrepresented in health research. 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. (more…)

MedicalResearch.com Interview with: Tasleem J. Padamsee, PhD Co-Leader  C3-REACH -- Committed to Communities Collaborative: Research and Engagement to Advance beyond COVID to Health EquityPrincipal Investigator The Daughter Sister Mother Project: Empowering Women and their Healthcare Providers to Fight Familial Cancer Lead Qualitative Investigator WOW Project: Washington & Ohio Workers Study Assistant Professor Division of Health Services Management & Policy, College of Public Health Faculty Affiliate, James Comprehensive Cancer Center The Ohio State University MedicalResearch.com:  What is the background for this study?  Response: This is a study about COVID-19 vaccine hesitancy in the United States. 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.

Author Interviews, CDC, COVID -19 Coronavirus, Emory, Heart Disease, JAMA / 25.01.2022

MedicalResearch.com Interview with: Matthew Oster, MD, MPH CDC COVID-19 Response CDC Center on Birth Defects and Developmental Disabilities Pediatric Cardiologist, Sibley Heart Center, Children’s Healthcare of Atlanta Emory University School of Medicine Emory University Rollins School of Public Health MedicalResearch.com:  What is the background for this study?  What are the main findings? 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. (more…)
Author Interviews, Critical Care - Intensive Care - ICUs, JAMA, Pediatrics / 18.01.2022

MedicalResearch.com Interview with: 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.  (more…)
Author Interviews, COVID -19 Coronavirus, JAMA, Pediatrics / 11.01.2022

MedicalResearch.com Interview with: Stephen Freedman MDCM, MSc Professor of Pediatrics and Emergency Medicine Alberta Children’s Hospital Foundation Professor in Child Health and Wellness Alberta Children’s Hospital Research Institute, Cumming School of Medicine University of Calgary MedicalResearch.com: What is the background for this study? 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.  (more…)
Author Interviews, Cannabis, JAMA, Pediatrics / 07.01.2022

MedicalResearch.com Interview with: Daniel Myran, MD, MPH, CCFP, FRCPC Family and Public Health and Preventive Medicine Physician CIHR Fellow, Ottawa Hospital Research Institute Department of Family Medicine Innovation Fellow University of Ottawa MedicalResearch.com: What is the background for this study? 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.

Author Interviews, JAMA, Prostate Cancer, Race/Ethnic Diversity, UCLA / 03.01.2022

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?  (more…)

Author Interviews, Diabetes, JAMA, Race/Ethnic Diversity, University of Pennsylvania / 20.12.2021

MedicalResearch.com Interview with: Lauren A. Eberly, MD, MPH Clinical Fellow, Cardiovascular Medicine Perelman School of Medicine Cardiovascular Division, Perelman School of Medicine Center for Cardiovascular Outcomes, Quality, and Evaluative Research, Cardiovascular Center for Health Equity and Social Justice, Leonard Davis Institute of Health Economics University of Pennsylvania, Philadelphia MedicalResearch.com: What is the background for this study? Response: Racial inequities are pervasive in our country, and cardiovascular therapeutics with proven benefit have been shown to be underutilized among Black and Latinx patients. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), a recommended treatment option for glycemic control in patients with diabetes, have recently emerged as a cardioprotective therapy as multiple large randomized clinical trials have shown they prevent cardiovascular events among patients with Type 2 Diabetes (T2D), particularly patients with established atherosclerotic cardiovascular disease (ASCVD). Given this, they are now recommended therapy for patients with diabetes and established or high risk of ASCVD. Given the known inequitable utilization of other therapies, along with the known higher burden of diabetes and cardiovascular disease among Black patients, the aim of this study was to evaluate the uptake of GLP-1 RA as well as for inequities in utilization.

Author Interviews, Cost of Health Care, JAMA, Kidney Disease, Social Issues, Transplantation / 14.12.2021

MedicalResearch.com Interview with: Rebecca Thorsness, PhD Research Associate Department of Health Services, Policy, and Practice Brown University School of Public Health  MedicalResearch.com: What is the background for this study? What are the main findings? Response: In 2019, the President signed the Advancing American Kidney Health executive order, which included provisions to increase the use of home dialysis and kidney transplant for Americans living with kidney failure. To carry out this vision, the Centers for Medicare & Medicaid Services (CMS) developed the ESRD Treatment Choices (ETC) payment model, which uses financial incentives and penalties to incentivize dialysis facilities to pursue home dialysis or kidney transplant for their patients. Transplant and home dialysis are optimal care for people with kidney failure, but there are social and clinical reasons that patients with high social risk (such as those exposed to racism, poverty, or housing instability) may not be candidates for these treatments. This means that facilities which serve a large number of patients with high social risk might be disproportionately penalized by this new payment model. Using data immediately prior to the implementation of the ETC model, we found that dialysis facilities that serve high proportions of patients with high social risk have lower rates of home dialysis and kidney transplantation than facilities that care for lower proportions of such patients.

Author Interviews, JAMA, Opiods, University of Pennsylvania / 14.12.2021

MedicalResearch.com Interview with: Ashish Thakrar, MD Internal Medicine & Addiction Medicine National Clinician Scholars Program University of Pennsylvania MedicalResearch.com: What is the background for this study? Response: About 1.8 million Americans are currently incarcerated, more than any other country in the world per capita. Of those 1.8 million, about 1 in 7 suffers from opioid addiction, putting them at high risk of overdose and death, particularly in the weeks following release. Opioid use disorder is a treatable condition, particularly with the medications buprenorphine or methadone, but historically, prisons and jails have not offered treatment. Over the past five years, a few states and municipalities have enacted policies to provide access for OUD treatment. We examined whether these policies were actually improving access to treatment.  (more…)
Aging, Alzheimer's - Dementia, Author Interviews, Blood Pressure - Hypertension, JAMA / 14.12.2021

MedicalResearch.com Interview with: Jan Willem van Dalen, PhD Department of Neurology Donders Institute for Brain, Behaviour and Cognition Radboud University Medical Centre Nijmegen Department of Neurology The Netherlands3Department of Public and Occupational Health Amsterdam UMC, University of Amsterdam, Amsterdam   MedicalResearch.com: What is the background for this study? Response: Although high systolic blood pressure in midlife has consistently been reported as a condition that increases the risk of developing dementia in old age, reports regarding this relationship in older people have been inconsistent. One potential reason for this, is that the relationship between systolic blood pressure and dementia in later life may be U-shaped, meaning that both individuals with low and with high systolic blood pressure are at increased incident dementia risk. This study combined data from several longitudinal cohort studies specifically designed to study incident dementia in older people, to investigate whether these U-shaped relationships exist, and in which age ranges they appear. We included more than 16,500 people aged 60 and older, with over 2,700 incident dementia cases. Also, we aimed to investigate whether these observational associations might be caused by confounding, differences in mortality, or result from opposite relationships between certain subgroups of individuals.

Author Interviews, COVID -19 Coronavirus, Critical Care - Intensive Care - ICUs, JAMA / 13.12.2021

MedicalResearch.com Interview with: Liise-anne Pirofski, M.D. Mitrani Professor of Biomedical Research Chief, Division of Infectious Diseases Albert Einstein College of Medicine and Montefiore Medical Center Liise-anne Pirofski, MD on behalf of lead authors Mila Ortigoza MD, PhD, Assistant professor at NYU Langone Health and Hyunah Yoon MD, Assistant Professor, Albert Einstein Medical Center and the CONTAIN COVID-19 trial authors and team MedicalResearch.com: What is the background for this study? Response: The study was designed to determine the efficacy of COVID-19 convalescent plasma (CCP) in hospitalized patients with COVID-19. It was designed and launched in New York City in April 2020 during the height of the first COVID-19 pandemic wave and later extended to sites in Miami, Houston, and other regions affected by subsequent waves of the pandemic. At that time, there were no validated therapeutic options for COVID-19, and there was clinical equipoise for CCP use in hospitalized patients. COVID-19 convalescent plasma was considered worthy of investigation because of the historical success of convalescent plasma in prior pandemics and epidemics dating to the beginning of the 20th century, and importantly, biological plausibility because convalescent plasma contains antibodies to agents from which people have recovered, and case series and observational studies showing signals of CCP efficacy in patients with COVID-19. The trial was designed to focus on patients with moderate to severe COVID-19 who required supplemental oxygen, but not mechanical intubation. At the time the trial was designed, hospitals in New York City were overwhelmed with severely and critically ill patients with COVID-19, an entirely new disease about which more and more was learned over the 11 months the trial was conducted.  (more…)
Author Interviews, Cost of Health Care, JAMA, Medicare / 12.12.2021

MedicalResearch.com Interview with: Jeanne Madden, PhD Associate Professor Department of Pharmacy and Health Systems Sciences School of Pharmacy and Pharmaceutical Sciences Bouvé College of Health Science Northeastern University MedicalResearch.com: What is the background for this study? Response: Medicare is the US public insurance program mainly serving people 65 years and older, but also some younger adults who have long-term disabling conditions. As such, on average, the Medicare population bears a heavy burden of illness and has high health care needs, compared to the general US population. The under-65 group for the most part has quite low incomes, while the older group represents a wide spectrum, from poor to well-off. Medicare beneficiaries also differ a great deal in terms of whether they have access to supplemental insurance that can help with patient cost-sharing requirements. I’m referring to Medicaid assistance, or a self-purchased Medigap plan, or retiree health benefits, etc. The cost-sharing requirements in traditional Medicare are substantial — e.g., 20% for doctor visits — and there is no annual cap on patient out-of-pocket spending. That’s in contrast to commercial insurance and Medicare Advantage managed care plans — all of those have an annual cap on patient out-of-pocket costs. There’s a good amount of existing research on whether people in Medicare can afford their drugs, and on the affordability of medical care among younger groups such as working-aged uninsured people and those in ACA exchange plans. But there hasn’t been much research into medical care affordability among older Americans. (more…)
Author Interviews, Dental Research, JAMA, Pediatrics, USPSTF / 10.12.2021

MedicalResearch.com Interview with: Michael Cabana, M.D., M.A., M.P.H Professor of Pediatrics Albert Einstein College of Medicine. Physician-in-chief , Children's Hospital at Montefiore Chair of the Department of Pediatrics Albert Einstein College of Medicine Member, U.S. Preventive Services Task Force  MedicalResearch.com: What is the background for this study and recommendation statement?  Response: Dental caries, also known as cavities or tooth decay, is the most common chronic disease in children in the United States and can develop in any child whose teeth have come in. Many young children under five years old do not visit a dentist, so the Task Force reviewed the latest evidence on how primary care clinicians can help prevent tooth decay in young children. The Task Force’s research led to two important findings: all young children whose teeth have come in should have fluoride varnish applied by their clinician, and all children six months and older whose water supply doesn’t contain enough fluoride should receive fluoride supplements. Both approaches can help prevent cavities in kids. The Task Force also determined that there is not enough evidence to recommend for or against screening for tooth decay in the primary care setting for children under five. This is consistent with the Task Force’s 2014 recommendation on dental caries. (more…)
Author Interviews, Gender Differences, JAMA / 09.12.2021

MedicalResearch.com Interview with: Christopher J. D. Wallis, MD, PhD Assistant Professor, Division of Urology University of Toronto Urologic Oncologist, Division of Urology Mount Sinai Hospital and University Health Network MedicalResearch.com: What is the background for this study? Response: Previous research has shown that female and male physicians communicate differently with patients. Further, there is evidence that female physicians, including surgeons, spend more time with patients. This, coupled with evidence that female patients may experience disparities in the management of their pain, led us to consider that communication differences may underpin differences in surgical outcomes previously noted (eg. Wallis et al, BMJ 2017) between male and female physicians. We postulated that there may be a differential association between surgeon sex and patient sex in behaviours that would translate into clinically important outcomes.

Alzheimer's - Dementia, Author Interviews, JAMA, Ophthalmology / 06.12.2021

MedicalResearch.com Interview with: Cecilia S. Lee, MD, MS Associate Professor,Director, Clinical Research Department of Ophthalmology Harborview Medical Center University of Washington Seattle, WA MedicalResearch.com: What is the background for this study? Response: Cataract is a natural aging process of the eye and affects the majority of older adults who are at risk for dementia. Sensory loss, including vision and hearing, is of interest to the research community as a possible risk factor for dementia, and also as a potential point of intervention. Because cataract surgery improves visual function, we hypothesized that older people who undergo cataract surgery may have a decreased risk of developing Alzheimer disease and dementia. We used the longitudinal data from an ongoing, prospective, community based cohort, Adult Changes in Thought (ACT) study. The ACT study includes over 5000 participants to date who are dementia free at recruitment and followed until they develop Alzheimer disease or dementia. We had access to their extensive medical history including comprehensive ophthalmology visit data. We investigated whether cataract surgery was associated with a decreased risk of developing Alzheimer disease and dementia.  (more…)
Author Interviews, JAMA, Johns Hopkins, Weight Research / 25.11.2021

MedicalResearch.com Interview with: Alejandra Ellison-Barnes, MD MPH General Internal Medicine Johns Hopkins Medicine MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Emerging adulthood is a unique period of development that ultimately leads to the formation of adult identity, but how this stage contributes to obesity is relatively understudied. The prevalence of obesity has been increasing in the United States population as a whole, and we wanted to know how mean body mass index and the prevalence of obesity have changed over the past several decades specifically among emerging adults. We found that among emerging adults aged 18 through 25, mean BMI has increased from 23.1 kg/m2 in 1976-1980 to 27.7 kg/m2 in 2017-2018. In the same period, the prevalence of obesity increased from 6.2% to 32.7%. (more…)
Author Interviews, JAMA, Mayo Clinic, Race/Ethnic Diversity, USPSTF / 20.11.2021

MedicalResearch.com Interview with: Chyke A. Doubeni, M.D., M.P.H. Member of the U.S. Preventive Services Task Force since 2017 Director, the Mayo Clinic Center Health Equity and Community Engagement Research Department of Family Medicine Mayo Clinic in Rochester, MN  MedicalResearch.com: What is the background for this study? What are the main findings? Response: People who experience systemic racism generally have shorter life expectancies and experience more health problems. Racism can increase the chances of getting preventable conditions, limit access to health information, and restrict access to actual preventive care. To confront these issues and promote antiracism and health equity, the Task Force commissioned a review of the evidence around how systemic racism currently undermines preventive healthcare. Based on that review, the Task Force has developed an initial set of strategies to reduce the effects of systemic racism, which includes prioritizing topics that are likely to advance health equity, assessing the Task Force’s language to ensure it is culturally appropriate, and calling for more research in people of color.  (more…)

Crescenz VA Medical Center in Philadelphia Penn Cardiovascular Outcomes, Quality & Evaluative Research Center MedicalResearch.com: What is the background for this study? What are the main findings? 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. (more…)
Author Interviews, Brigham & Women's - Harvard, Heart Disease, JAMA, Lipids / 16.11.2021

MedicalResearch.com Interview with: 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? (more…)
Author Interviews, Coffee, Heart Disease, JAMA, OBGYNE / 09.11.2021

MedicalResearch.com Interview with: 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.   (more…)
Author Interviews, COVID -19 Coronavirus, JAMA, Vaccine Studies / 04.11.2021

MedicalResearch.com Interview with: Rani Elwy, PhD Bridge Quality Enhancement Research Initiative Program, Center for Healthcare Organization and Implementation Research, VA Bedford Healthcare System Bedford, Massachusetts Department of Psychiatry and Human Behavior, Alpert Medical School Brown University, Providence, Rhode Island  MedicalResearch.com: What is the background for this study? 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. (more…)
Author Interviews, Infections, JAMA, Multiple Sclerosis, Neurological Disorders / 27.10.2021

MedicalResearch.com Interview with: 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, Brigham & Women's - Harvard, JAMA, Surgical Research / 27.10.2021

MedicalResearch.com Interview with: 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.  (more…)
