Author Interviews, Environmental Risks, Pediatrics, Toxin Research / 07.03.2022

MedicalResearch.com Interview with: Jeanette Stingone PhD Assistant Professor, Epidemiology Mailman School of Public Health Columbia University MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: Lead is a well-established neurotoxin, particularly when exposure occurs early in life and in childhood. Associations between elevated blood lead levels and lower scores on tests of neurodevelopment and cognition are seen consistently across studies, even when examining lower levels of exposure. While reducing exposure to lead is the primary intervention to prevent these adverse outcomes, there aren’t many interventions designed to support the neurodevelopment of children who have been exposed to lead. Some municipalities consider elevated blood lead levels as a criteria for inclusion in Early Intervention programs. Early Intervention programs are mandated under the Individuals with Disabilities Education Act and provide services for children younger than 3 years old with disabilities or developmental delays. The objective of this study was to compare 3rd grade standardized test scores among children who had elevated blood lead levels early in life to see if children who had received Early Intervention services performed better on these tests than those who did not receive services. Using matching methods and an existing administrative data linkage of children who were born and attended public school in New York City, we observed that children exposed to lead who received Early Intervention services scored higher on standardized tests in both math and English Language arts than children exposed to lead who did not receive services.  (more…)
Author Interviews, Exercise - Fitness, Heart Disease, JNCI / 03.03.2022

MedicalResearch.com Interview with: Fiona Bartoli PhD Leeds Institute of Cardiovascular and Metabolic Medicine University of Leeds  MedicalResearch.com:  What is the background for this study?  Response: Physical activity improves our health and reduces the risk of developing cardiovascular disease, diabetes, depression or even cancer. However, sedentary lifestyles are increasing, and people fail to exercise enough, for reasons such as illnesses, injuries, or computer usage. This puts people at more risk of disease. During physical exercise, the heart beats faster so more blood is pumped through the body. The very large protein called Piezo1 is found in the lining of blood vessels and acts as an “exercise sensor” by detecting the change in blood flow during exercise and acting accordingly.

Author Interviews, Biomarkers, Heart Disease, NEJM / 03.03.2022

MedicalResearch.com Interview with: PJ Devereaux MD PhD Professor of Medicine, and of Health Research Methods, Evidence and Impact McMaster University President of the Society of Perioperative Research and Care  MedicalResearch.com:  What is the background for this study?  Response: More than 1 million patients undergo cardiac surgery in the United States and Europe annually. Although cardiac surgery has the potential to improve and prolong a patient’s quality and duration of life, it is associated with complications. Prognostically important heart injury – detected by an elevated blood concentration of either cardiac troponin or creatine kinase myocardial MB isoform (CK-MB) – is one of the most common complications after cardiac surgery and is associated with increased mortality. Although elevated CK-MB was historically used to define heart injury after cardiac surgery, this assay is no longer available in many hospitals worldwide, and consensus statements have recommended high-sensitivity cardiac troponin assays as the preferred biomarker. Based on expert opinion, the Fourth Universal Definition of Myocardial Infarction suggested that a cardiac troponin concentration >10 times the upper reference limit, in patients with a normal baseline measurement, should be the threshold used in the diagnosis of heart attack along with evidence of ischemia (e.g., ischemic ST changes on an ECG) in the first 48 hours after coronary artery bypass grafting (CABG). Although the Academic Research Consortium-2 Consensus stated there was no evidence-based threshold for cardiac troponin after CABG, they endorsed a threshold for the diagnosis of heart attack of ≥35 times the upper reference limit together with new evidence of ischemia, based on expert opinion. They also defined a threshold of ≥70 times the upper reference limit as a stand-alone criterion for clinically important periprocedural myocardial injury. Globally, many hospitals now use high-sensitivity cardiac troponin assays; however, limited data are available to define a prognostically important degree of myocardial injury after cardiac surgery based on these assays. We undertook the Vascular Events in Surgery Patients Cohort Evaluation (VISION) Cardiac Surgery Study to examine clinical outcomes after cardiac surgery. A primary objective was to determine the relationship between postoperative levels of high-sensitivity cardiac troponin I and the risk of death 30 days after cardiac surgery.  (more…)
Anesthesiology, Author Interviews, Columbia, JAMA, OBGYNE / 28.02.2022

MedicalResearch.com Interview with: Jean Guglielminotti MD,PhD Assistant Professor of Anesthesiology Columbia University Irving Medical Center New York 10032  MedicalResearch.com:  What is the background for this study?  Response: An old study (2004-2006) conducted in France suggested that epidural analgesia during childbirth resulted in a decreased risk of postpartum hemorrhage, the first cause of preventable maternal morbidity and mortality. We believed it was important to replicate this study in the United States, because of the advances in obstetric and anesthesia care practices during the last 15 years, and because of the marked differences in the health care systems between the United States and France.

Allergies, Author Interviews / 26.02.2022

MedicalResearch.com Interview with: Edmond S. Chan MD, FRCPC, FCSACI, FAAAAI Head | Division of Allergy & Immunology | Department of Pediatrics, Faculty of Medicine Clinical Professor, The University of British Columbia Clinical Investigator, BC Children's Hospital Research Institute BC Children's Hospital, Allergy Clinic Vancouver, BC  Canada Treasurer, CSACI (Canadian Society of Allergy & Clinical Immunology) MedicalResearch.com:  What prompted you to look at the safety of peanut oral immunotherapy specifically in this patient population? Response: Our previous research has investigated the overall safety of peanut oral immunotherapy (OIT) in preschool populations. However, we have not investigated the relationship between specific patient characteristics and the safety of OIT. Previous literature has shown that patient factors, such as age, gender, baseline sIgE levels, and atopic comorbidities have been shown to impact the safety of OIT for other food allergies and in older patients. However, no data exist on which factors predict safety of peanut OIT in preschool populations. (more…)
Author Interviews, Dermatology, Diabetes / 22.02.2022

MedicalResearch.com Interview with: Chih-Shan Jason Chen, MD, PhD Director, Dermatologic and Mohs Micrographic Surgery Unit Memorial Sloan Kettering Skin Cancer Center at Hauppauge Attending Mohs Surgeon, Dermatology Service Memorial Sloan Kettering Cancer Center Chief, Dermatologic Surgery Northport VA Medical Center Associate Professor of Clinical Dermatology Renaissance School of Medicine at Stony Brook University MedicalResearch.com:  What is the background for this study?    Response: Managing a surgical wound on the lower leg can be a challenge. Often, higher wound tension, atrophic skin, edema, and compromised circulation result in higher risks of wound dehiscence and infection, and significantly limit the capacity of wound closure post-surgically. Therefore, healing by secondary intention is a practical option for many lower leg Mohs defects. However, a secondary intention wound on the lower leg is expected to take a longer time to heal. Certain factors such as older age and health conditions of the host may adversely affect healing time. Timolol is a nonselective beta-adrenergic receptor antagonist that has FDA approval for the treatment of glaucoma. In addition to this FDA-approved indication, topical timolol has several off-label uses in dermatology, such as for the treatment of infantile hemangiomas, venous stasis ulcers, and refractory wounds. Although timolol solution has been used in chronic wounds, knowledges of the efficacy and utility of timolol in an acute post-surgical wound setting is lacking. (more…)
Author Interviews, Insomnia, Pediatrics / 17.02.2022

MedicalResearch.com Interview with: Julio Fernandez-Mendoza, PhD, CBSM, DBSM Associate Professor of Psychiatry & Behavioral Health Sleep Research & Treatment Center Director, Behavioral Sleep Medicine Program Penn State Health Milton S. Hershey Medical Center MedicalResearch.com:  What is the background for this study?  Is insomnia familial? Response: Consistent research has shown that about 25% of school-age children have insomnia symptoms consisting of difficulties initiating or maintaining sleep. However, what has remained unknown is to what extent those insomnia symptoms persist all the way into adulthood, or whether they developmentally remit (go away with age) as the child grows into adolescence or young adulthood. This is the question that our study focused on. (more…)
Addiction, Author Interviews / 17.02.2022

MedicalResearch.com Interview with:

Harriet De Wit, PhD Professor of Psychiatry and Behavioral Neuroscience University of Chicago 

MedicalResearch.com:  What is the background for this study?    Response: There are numerous reports that psychedelics like LSD, taken in very small ‘microdoses’, help boost mood, cognitive function and productivity. The practice is popular in Silicon Valley and among media figures, who report remarkable beneficial effects from regular use of these microdoses. The possible antidepressant effects of LSD are plausible from a neurobiological perspective, as the drug acts directly on serotonin receptors, the same systems where SSRI’s act.  However, the effects of microdosing have not yet been validated in controlled research. In our study, we recruited healthy men and women to ingest repeated, low doses of LSD under double blind conditions.  They attended four laboratory sessions, separated by three to four days.  They were randomly assigned to one of three groups who received the same drug on all four sessions: placebo, 13 micrograms of LSD or 26 micrograms of LSD. Subjects were not told exactly what drug they were receiving until the end of the study.  We measured their mood, emotional reactivity and cognition. (more…)
Author Interviews, JAMA, OBGYNE, STD / 16.02.2022

MedicalResearch.com Interview with: Irene A. Stafford, M.S., M.D. Associate Professor Associate Program Director Maternal - Fetal Medicine Fellowship Department of Obstetrics and Gynecology Division of Maternal Fetal Medicine McGovern Medical School at UTHealth Houston MedicalResearch.com:  What is the background for this study? Response: We have observed disproportionately high-rates syphilis in the US over the last several years, and here in Texas. As this is now leading to health alerts in our cities, it is key we bring attention to this infection regarding risks to the pregnant patient and her fetus. Syphilis carries a nearly 40% neonatal mortality rate, so testing and treating is key in preventing this devastating neonatal infection. We need to encourage and offer testing at intake to pregnancy care, and any time a patient desires to be tested for STI.   (more…)

MedicalResearch.com Interview with: Izzuddin M Aris, PhD Assistant Professor Department of Population Medicine, Harvard Medical School Division of Chronic Disease Research Across the Lifecourse Harvard Pilgrim Health Care Institute Boston, MA MedicalResearch.com:  What is the background for this study?  Response: Puberty is a key stage during child development. Previous research indicates that children in the United States are entering puberty at younger ages. These children may be in danger of developing certain diseases, such as type 2 diabetes, later in life. A better understanding of how early life factors affect puberty development is important for combating earlier puberty onset. . (more…)

MedicalResearch.com Interview with: Kao-Ping Chua, MD, PhD Assistant Professor, Department of Pediatrics Assistant Professor, Health Management and Policy School of Public Health University of Michigan MedicalResearch.com:  What is the background for this study? Response: In 2020, most insurers waived the cost of COVID-19 hospitalization for patients. In early 2021, many major insurers started to abandon those waivers. By August 2021, the vast majority of insurers had started billing patients for COVID-19 hospitalizations again. (more…)

MedicalResearch.com Interview with: Dr. Saundra Singh M.D., Ph.D. Founder & CEO/President Singh Biotechnology https://www.singhbiotechnology.com/       MedicalResearch.com: What is the mission of Singh Biotechnology?  
  • Our mission is to develop medicine and therapeutics that dramatically improve and save the lives of people worldwide suffering from diseases, including cancer.
MedicalResearch.com: What are the advantages of the Single Domain Antibody technology?
  • The average human antibody is 150 Kd in size and works on the outside of the cell. The advantage of the single domain nanobody is that it is significantly smaller, in fact, it is one-tenth the size (approximately 15 Kd) of the human antibody. A smaller nanobody is more useful therapeutically because, unlike many cancer drugs currently on the market, it can penetrate the blood-brain barrier, the blood-retina barrier, and the cell membrane. Moreover, our SBT-100 drug has been shown to be non-toxic in animal models.

Author Interviews, Environmental Risks, Fertility, OBGYNE / 08.02.2022

MedicalResearch.com Interview with: Gang Chen, MD, PhD Deputy chief of cardiovascular surgery Children's Hospital of Fudan University Shanghai, Chin  MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: Preterm birth is a crucial global health issue. The relation between fertility treatment and preterm birth of singletons have not been fully clarified. In this cohort study of over 14 million pregnant women included in the US National Vital Statistics, fertility treatment, including both assisted reproductive treatment (ART) and non-ART treatment, was found positively correlated with preterm birth in singletons and infants conceived after fertility treatment were more strongly associated with higher rates of very preterm and extremely preterm birth.  (more…)

MedicalResearch.com Interview with: Bianca V. Sanchez Department of Medical Education Geisinger Commonwealth School of Medicine Scranton, Pennsylvania MedicalResearch.com: What is the background for the study? Response: Hispanic populations have been disproportionately affected by the COVID-19 pandemic, as evident by their increased rate of infection with the virus, hospitalizations, and mortality. Previous literature has indicated that many of these individuals demonstrate increased rates of vaccine hesitancy, subsequently increasing their risk for infection. This study aimed to characterize the reasoning behind vaccine hesitancy in Hispanic populations in the hopes of addressing their concerns through targeted educational interventions. (more…)
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.

Addiction, Author Interviews, Opiods, PLoS / 04.02.2022

MedicalResearch.com Interview with: Dr. Laurence Moss MD, PhD candidate Centre for Human Drug Research (CHDR) Department of Anesthesiology Leiden University Medical Centre (LUMC) Geert Jan GroeneveldMD, PhD Neurologist | Clinical Pharmacologist | Professor of Clinical Neuropharmacology CMO/CSO Centre for Human Drug Research Leiden, The Netherlands  MedicalResearch.com:  What is the background for this study?    Response: Opioid use disorder (OUD) is a major source of morbidity and mortality, and the opioid epidemic in the Unites States (but increasingly in Europe also) has been well documented and reported on by the media. The alarming rise in opioid related mortality is largely driven by the increasing use of fentanyl and fentanyl analogues, often surreptitiously mixed with heroin or other drugs such as psychostimulants or prescribed opioids. Opioid-induced respiratory depression in particular is a leading cause of opioid-related fatalities. Buprenorphine has been proven as an effective medication for the treatment of OUD. Buprenorphine is a semi-synthetic partial agonist for the opioid receptor that firmly binds to these receptors and displays only partial respiratory depressive effects, meaning it does not cause the complete cessation of breathing as is the case with other potent opioids such as fentanyl. Due to its firm receptor binding, we hypothesized that at sufficient buprenorphine receptor occupancy, the effect of fentanyl on respiration would be limited, even at high fentanyl doses. This study aimed to provide proof of principle for this hypothesis, and demonstrate whether buprenorphine could reduce fentanyl-induced respiratory depression. (more…)

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…)

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.

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…)

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…)

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…)
