MedicalResearch.com Interview with: [caption id="attachment_48843" align="alignleft" width="200"]Keerat Grewal, MD, MSc, FRCPC Schwartz/Reisman Emergency Medicine Institute Mount Sinai Hospital Toronto, ON Dr. Grewal[/caption] Keerat Grewal, MD, MSc, FRCPC Schwartz/Reisman Emergency Medicine Institute Mount Sinai Hospital Toronto, ON  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Patients with cancer have complex care requirements and often use the emergency department. The purpose of our study was to determine whether continuity of care, cancer expertise, or both, impact outcomes among cancer patients in the emergency setting. Using administrative data we looked at adult patients with cancer who received chemotherapy or radiation therapy in the 30 days prior to an emergency department visit.

Response: Previous studies in workers exposed to very high levels of polychlorinated biphenyls (PCBs) have suggested hazardous health effects. However, circulating PCB levels are detected in almost all indivuduals in industrialized countries, but the health effects of moderately elevated levels as seen in the general population are not well established. We investigated levels of PCBs in around 1,000 individuals, all aged 70 years, randomly chosen from the City of Uppsala, Sweden.

MedicalResearch.com: What is the background for this study? Response: Oral health is an important component of general health and yet dental caries (decay) is still common in children (affecting up to one in three 5-6 year old children in Australia). Although we know that some genetic and lifestyle factors (such as diet) are important risk factors for caries, the relative importance of these is still unclear.  Risk factors from pregnancy and very early childhood (even before teeth appear) might also be important. This study is the first to include prospectively measured data on health and well-being from pregnancy, birth and early childhood in a study of twin children. We analysed data from a cohort of 172 pairs of twin children to assess the effects of genes and environment on susceptibility to dental caries at six years-of-age.

MedicalResearch.com Interview with: [caption id="attachment_48846" align="alignleft" width="200"]Leah LaRue, PharmD, PMPAssociate Director, Clinical AffairsMillennium Health Dr. LaRue[/caption] Leah LaRue, PharmD, PMP Associate Director, Clinical Affairs Millennium Health MedicalResearch.com: What is the background for this study? Response: Drug overdose deaths continue to increase, despite the leveling off of prescription opioid use and policy changes limiting opioid prescribing. While fentanyl has garnered most of the attention, overdose deaths involving cocaine and methamphetamine also have increased markedly over the past few years. It is possible that those increases are due not just to those drugs, but to concomitant use with fentanyl. To better understand what is causing this rapid increase in overdose deaths, it is important to characterize the emerging combination of other illicit drugs with fentanyl, which increases the risk of overdose. The purpose of this study was to determine whether rates of the combination of nonprescribed fentanyl with cocaine or methamphetamine have changed in urine drug test (UDT) results through time.
Author Interviews, Nutrition, Weight Research / 28.04.2019

MedicalResearch.com Interview with: Dale Morrison, PhD School of Exercise and Nutrition Sciences Institute for Physical Activity and Nutrition MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The study was conducted using a model of overfeeding that is likely to be representative of a typical Western overeating diet, high in both carbohydrates and fats; as opposed to a predominantly high-fat diet model that is commonly used in the literature. Our purpose was to examine which tissues are impaired first in response to overeating with a normal dietary composition. We initially hypothesized, based on earlier studies, that the liver would be impaired first by short-term overeating and then skeletal muscle (which soaks up much of the glucose following a meal) would be impaired much later with chronic overeating. However, we didn’t find this. The study found that the body copes with short periods of overeating with additional carbohydrates and makes adjustments by shifting metabolism towards utilizing these excess carbohydrates.

V. Jaddoe, MD, PhD Adjunct Professor of Epidemiology Department of Epidemiology MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Childhood body fat may be affected by patterns of fetal and infant weight change. Children born small for gestational age (SGA) tend to have infant growth acceleration, whereas those born large for gestational age (LGA) tend to have infant growth deceleration. Little is known about fetal and infant growth patterns affecting visceral, liver, and pericardial fat, which are strongly associated with cardiometabolic disease in later life. We assessed in a large population cohort study whether fetal and infant weight change was associated with not only general, but also organ fat at school age. We observed that fetal and infant weight change patterns were both associated with childhood body fat, but weight change patterns in infancy tended to have larger effects. Fetal growth restriction followed by infant growth acceleration was associated with increased visceral and liver fat.

Would you tell us a little about focal segmental glomerulosclerosis (FSGS)? How does ANG-3070 work to prevent kidney scarring? Response: Angion has received a follow-on grant from the Department of Defense (DoD) for $4.76 million in support of the development of ANG-3070, our drug candidate for a form of chronic kidney disease known as focal segmental glomerulosclerosis (FSGS). This funding will allow us to expand our proof-of-concept data for ANG-3070 as a potential anti-fibrotic agent for slowing the progression of FSGS. FSGS is a serious kidney disorder characterized by progressive scarring of the glomeruli, the filtering units of the kidney. There are approximately 80,000 cases of FSGS in the U.S. and Europe, involving both children and young adults. If uncontrolled, FSGS can lead to kidney failure, which may lead to the need for dialysis or a kidney transplant. No therapies exist that treat the underlying cause of FSGS. Therapies such as corticosteroids, immunosuppressants or diuretics  are used, but are mainly supportive and a large proportion of patients progress to end-stage renal disease over a 5-10 year period of time. ANG-3070 is an oral small molecule that selectively inhibits molecular pathways associated with scarring or fibrosis in the kidney and other organs. Our current preclinical study in collaboration with NEPTUNE aims to identify the “signalosome,” or human disease and drug response profile based on the genes, networks and pathways that correlate with the therapeutic activity of ANG-3070 in FSGS. Ultimately, this collaboration will allow us to  develop a precision medicine approach to identify and treat patients in whom ANG-3070 is most likely to block the pathways causing FSGS.

MedicalResearch.com Interview with: Angela Eichelberger, Ph.D. Senior Research Scientist Insurance Institute for Highway Safety MedicalResearch.com: What is the background for this study? Response: Dr. Romano and Dr. Kelley-Baker have previously studied the problem of child endangerment in alcohol-related crashes. In the United States, each year, about 200 children die and another 4,000 are injured while being driven by a drinking adult. For this study, we wanted to take the opportunity to look at the prevalence of alcohol and cannabis use among drivers who participated in a roadside survey in Washington State. To our knowledge, this is the first study to examine cannabis use among drivers transporting a child.

MedicalResearch.com Interview with: Yoshinori SUGIURA Ph.D. Associate Professor Hiroshima University Graduate School of Integrated Arts and Sciences Behavioural Sciences Section Higashi-Hiroshima, Japan  MedicalResearch.com: What is the background for this study? Response: Lengthy worrying or repeated checking if the door is locked are common manifestations of anxiety in the general population. However, if their frequency, intensity, and interference become too much, they are diagnosed as Generalized Anxiety Disorder (GAD) and Obsessive Compulsive Disorder (OCD) respectively. People with OCD are tortured by repeatedly occurring negative thinking and they take some strategy to prevent i. GAD is a very pervasive type of anxiety. GAD patients worry about everything. Despite their burden, both are relatively difficult to treat. Furthermore complicated, as they are two different disorders, mental health professionals have to master separate strategies. To overcome such situation, transdiagnostic research, which seeks common causes for different disorders, is now eagerly pursued by psychologists/psychiatrists. As one of such endeavors, we predicted that inflated responsibility is the common predictor of both OCD and GAD symptoms.

What are the main findings? Response: Most high-income countries now use acellular pertussis vaccines (called DTaP, which are sub-unit vaccines based on purified antigens of the bacterium Bordetella pertussis) to protect children against pertussis. Although clinical trials demonstrated the short-term effectiveness of DTaP vaccines, there was a growing concern that the duration of protection they conferred was not very long. Those concerns were mostly based on the results of a number of epidemiological studies, which showed that the relative risk of contracting pertussis increased substantially over time, typically by 20–40% every year since last vaccination. Although such increases seem high, it was not immediately obvious how to interpret them—the more so because pertussis epidemiology is complex. In our study, we developed mathematical models of pertussis epidemiology to try to understand what the results of recent epidemiological studies really meant about the effectiveness and the duration of protection of DTaP vaccines. The most interesting—and perhaps counterintuitive—finding of our study was that those results are fully consistent with highly effective DTaP vaccines, which confer long-term protection. This is a consequence of the fact that pertussis is highly contagious and that the immunity conferred by DTaP, though very high, is not perfect.

To view a copy of this license, visit: https://creativecommons.org/licenses/by/2.0Dr. Yi Liu Department of ophthalmology, Beijing Tongren Hospital, Beijing, P.R.China  MedicalResearch.com: What is the background for this study? Response: Though rare, sports-related ocular traumas may result in devastating and disabling consequences. Badminton is popular in Southeast Asia, such as in Malaysia, Philippines, Indonesia, and China. It is in the leading cause list of sport-related ocular injury. Badminton related ocular injuries were also occurred and reported in western countries such as Canada, Australia. The popularity of badminton is partially because it is considered relatively safe, as it does not involve physical contact. The growing popularity of badminton has led to an increased incidence of physical and ocular injuries. Although the latter are uncommon, they can lead to significant ocular morbidity and some patients suffer a permanent decrease in vision, and even blindness. We believe that the awareness of badminton-related ocular injuries is of great importance. The main purpose of this study was to summarize the clinical sports-related features of 85 patients with badminton related ocular injuries and made preventive recommendations to the general population from ocular injuries in badminton playing.

What are the main findings? Response: Schizophrenia is a severe disorder that presents in late adolescence or early adulthood with declining function, social withdrawal and psychotic symptoms such as auditory hallucinations and fixed false beliefs. It is a common condition, affecting 1% of the population, which can be not yet be prevented or cured. Its causes are still puzzling. Evidence from many different research approaches now suggests that an overactive immune system plays some role in causing schizophrenia, but the origins of the immune dysfunction are not known. We considered that too brief a period of sexual contact between parents could cause immune activation in offspring and thus be a risk factor for schizophrenia. With repeated sexual contact the maternal immune system develops tolerance to genetic material from the father. Otherwise, inflammatory processes may restrict the placental blood supply between the fetus and mother.

What are the main findings?  Response: Our study provides novel insight into the relationship between the immune system and eating disorders characterized by chronic restriction (e.g., anorexia nervosa) and binge eating and/or purging (e.g., binge eating disorder, bulimia nervosa). These findings also add to the growing body of literature linking the immune systems broadly and mental disorders. We found that infections in early childhood were associated with an increased risk of anorexia nervosa, bulimia nervosa, and other eating disorders such as binge eating disorder in adolescence. These relationships appear to be both time and dose-dependent, meaning that the onset of eating disorder diagnosis is greatest in the first three months following the infection, and the more infections, the greater the risk.

Response: Classically, the retina and the central nervous system (CNS) have long been considered immunoprivileged sites within the body. This is not to say that these sites lack immunity; rather, they are capable of exhibiting a contained yet modifiable form of immunological response. Indeed, an intricate immune surveillance system exists within the retina that can interact with the retinal cellular milieu both during development and in response to injury or disease. While activation of this surveillance system can help protect and repair the delicate neural tissue of the retina in certain disease states, over-activation of this system can exacerbate disease pathology, thereby worsening vision loss. Microglia are the resident immune cells of the central nervous system, including the retina, and are thought to function acutely in the homeostatic maintenance of the neuro-retinal microenvironment.  However in chronic conditions, like autoimmune uveitis, we hypothesized that microglia become neurodegenerative. In our current study we show for the first time a role for microglia in directing the initiation of this autoimmune disease by orchestrating the inflammatory response within the retina through the retinal vessels.
Alcohol, Author Interviews, Hepatitis - Liver Disease, Lifestyle & Health, Sugar / 25.04.2019

MedicalResearch.com Interview with: E. van Eekelen, MSc | PhD Candidate Leiden University Medical Center Dept. Clinical Epidemiology Leiden, The Netherlands MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Fatty liver, defined as excess accumulation of fat within the liver, covers a broad clinical spectrum and is the leading cause of chronic liver diseases. It has also been linked to type 2 diabetes and cardiovascular disease. The consumption of alcohol is a well-established risk factor for fatty liver. However, we hypothesized that consumption of non-alcoholic energy-containing beverages also leads to liver fat accumulation. We analysed data from the Netherlands Epidemiology of Obesity (NEO) study, which is a prospective population-based cohort study including non-invasive measurements of liver fat content by magnetic resonance spectroscopy. Besides consumption of alcoholic beverages, sugar sweetened beverages were associated with more liver fat. We specifically showed that replacement of alcoholic beverages with milk was associated with less liver fat, whereas replacement with sugar sweetened beverages was associated with a similar amount of liver fat, even when taking calories into account.

Senior Lecturer and Clinical Psychologist Interdisciplinary Department of Social Sciences Max & Anna Webb St. Ramat-Gan, Israel, 5290002   MedicalResearch.com: What is the background for this study?   Foundation: This study was conceptualized during a conversation we had, namely, Dr. Yaakov Hoffman, Interdisciplinary department of social sciences, Bar Ilan University, and Professor Menachem Ben-Ezra School of Social Work, Ariel University, following the release of the Antman movie. We are both psychologists who are also avid Marvel  superhero fans. In this meaningful conversation we discussed the issue of fear of insects which led to the idea that positive exposure to phobic stimuli (exposure to spider or ants) within the context of Marvel superheroes will lead to robust reduction in phobic symptoms. As most of the conventional treatments for specific phobias use exposure to the phobic stimuli in neutral contexts, we thought that framing the exposure in a positive fun, albeit fantasy context would yield robust results, as well as perhaps reducing stigma.

Hauck, MD, MS Spencer P. Bass, MD Twenty-First Century Professor of Family Medicine Professor of Public Health Sciences Director, International Family Medicine Clinic University of Virginia Department of Family Medicine MedicalResearch.com: What is the background for this study? Response: Unintentional suffocation is the leading cause of injury deaths among infants under one year of age in the US. 82% of these deaths are attributed to accidental suffocation and strangulation in bed. The Sudden Unexpected Infant Death Case Registry was established by the Centers for Disease Control and Prevention (CDC) in 2009 to collect data on sudden unexpected infant deaths (SUID) to better understand trends and characteristics associated with these deaths. Data from 10 states, which account for about one-third of all US SUID cases, are captured in the Registry. The CDC developed the Case Registry classification system in 2014 to differentiate SUID cases into several groups; explained suffocations with unsafe sleep factors is one of those categories, and the subject of this study. We analyzed infant deaths (children under one year of age) that occurred from 2011-2014 among states participating in the registry at the time of the study (Arizona, Colorado, Georgia, Louisiana, Michigan, Minnesota, New Hampshire, New Jersey, New Mexico, and Wisconsin). Among the 1812 cases in the Registry from 2011-2014, 250 (14%) were classified as suffocation. The remaining cases were classified as unexplained SUID.

[caption id="attachment_48766" align="alignleft" width="130"]Florian Kronenberg Dr. Kronenberg[/caption] MedicalResearch.com Interview with: Florian Kronenberg, MD Division of Genetic Epidemiology Department of Medical Genetics, Molecular and Clinical Pharmacology Medical University of Innsbruck, Innsbruck, Austria MedicalResearch.com: What is the background for this study? Response: Lp(a) is one of the most prevalent lipoprotein risk factors for cardiovascular disease. Roughly 20% of the general Caucasian population have concentrations above 50 mg/dL and the 10% with the highest concentrations have a 2 to 3-fold increased risk for myocardial infarction. There is strong evidence from genetic studies that high Lp(a) concentrations are causally related to cardiovascular outcomes. Until recently there was no drug available which lowers Lp(a) without any effects on other lipoproteins. This has recently changed by the development of drugs that block the production of Lp(a) in an impressive way. These drugs have to be studied in randomized controlled trials whether they not only lower Lp(a) concentrations but also cardiovascular outcomes. For the planning of such studies it is crucial to estimate the amount of Lp(a) lowering required to show a clinical benefit.

Kruger PhD Clinical Assistant Professor Department of Community Health and Health Behavior School of Public Health and Health Professions University of Buffalo Daniel J. Kruger PhD Adjunct Faculty Associate, Population Studies Center. Michigan's Population Studies Center  MedicalResearch.com: What is the background for this study? Response: The legal environment for cannabis is changing rapidly and an increasing proportion of people are using cannabis for medical and recreational purposes. All policy and practice should be informed by science, yet there is a large gap between evidence and existing practices, and the current scope of research on cannabis users is limited. Public Health has the responsibility of protecting the public, maximizing benefits and minimizing harm in any area. However, the Public Health approach to cannabis has largely been limited to a focus on abstinence, and Federal regulations have restricted the scope of cannabis-related research.

What are the main findings? Response: Our research group has been interested for a number of years in how stress hormones (called glucocorticoids) influence the risk of heart disease and diabetes. Glucocorticoids help us control stress and regulate how the body handles its fuel, for example the carbohydrate and fat we eat. However exposure to high levels of glucocorticoids, can increase the risk of diabetes, obesity and high blood pressure. We studied men with prostate disease who took 5α-reductase inhibitors, because over and above the beneficial actions of these drugs in the prostate, they also slow down inactivation of glucocorticoids. We had carried out some short term studies with the drugs in humans and found that they reduced the ability of insulin to regulate blood glucose. Therefore in the study we have just published in the BMJ, we examined how patients receiving these drugs long-term responded and particularly we were able to show that over an 11 year period that there was a small additional risk of developing type 2 diabetes, the type of disease common in older people, compared with other types of treatments.

Mick Tilford, PhD, Professor and Chair Department of Health Policy and Management Fay W. Boozman College of Public Health University of Arkansas for Medical Science   MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Prematurity and low birthweight are associated with increased risk of infant mortality as well as increased risk of chronic conditions throughout infancy and into adulthood. Non-Hispanic black infants are twice as likely to be born low birthweight (13.9% vs 7.0%) and 1.5 times as likely to be born prematurely (13.9% vs 9.1%) compared to non-Hispanic white infants. Under the Affordable Care Act (ACA), states may expand Medicaid to adults with household income levels at or below 138% of the federal poverty level, thus extending coverage to childless adults and improving continuity. Insurance gain may ultimately improve maternal health, increased use and earlier initiation of prenatal care services, and improved access to pregnancy planning resources. Our study aimed to evaluate whether there were changes in rates of low birthweight and preterm birth outcomes among states that expanded Medicaid versus states that did not expand Medicaid.

These changes included the addition of fruits, vegetables, and whole grains; a reduction in the amount of dairy and juice; and a calibration in formula amounts to match infants’ age and needs. We found that this change in the food package was associated with a 10-12% lower obesity risk at age 4 years among children who participated in WIC in Los Angeles County continuously from birth until age 4.

What are the main findings?  Response: Unintentional suffocation is the leading cause of injury death among infants under 1 year old in the US. This study investigates cases in CDC’s SUID Case Registry that were assigned the category of explained suffocation with unsafe sleep factors per CDC’s SUID Case Registry classification system, which was developed to consistently differentiate SUID cases into well-defined categories (including no autopsy or death scene investigation, incomplete case information, no unsafe sleep factors, unsafe sleep factors, possible suffocation with unsafe sleep factors, and explained suffocation with unsafe sleep factors) using standardized criteria and definitions. Cases classified as possible and explained suffocation were assigned one more mechanisms to which the airway obstruction was attributed including soft bedding, wedging, overlay and other – other was excluded from this analysis. Most explained suffocations (69%) were attributed to soft bedding like a blanket or a pillow followed by overlay (19%), and wedging (12%). Although explained suffocation deaths represent a small proportion of all sudden unexpected infant deaths (14%), these losses are particularly tragic because they can be prevented by placing a baby to sleep in a safe environment.

MedicalResearch.com interview with: Sylvain Lamure, MD, Hematologist, Principal Investigator Pascale Fabbro-Peray, MD, PhD , Epidemiologist, Senior Investigator University of Montpellier, France MedicalResearch.com: What is the background for this study? Response: Occupational exposure to pesticides is a well-documented associated factor for non-Hodgkin lymphoma. The main biological mechanisms of both pesticides and chemotherapy are genotoxicity and reactive oxygen species generation. Cellular adaptation among patients exposed to low doses of genotoxic and oxidative compounds might hinder chemotherapy efficiency in lymphoma patients. T hus, we have investigated the association of occupational exposure with response to immunochemotherapy and survival in the subgroup of diffuse large B cell lymphoma, whose treatment is standardized.

What are the main findings? Response: Sugar-sweetened beverage consumption has been linked to many negative health conditions, such as weight gain, dental caries, and type 2 diabetes. Previous research found that when you replace sugar-sweetened beverages (SSBs) with water intake then total energy intake goes down. We wanted to know how many calories from SSBs children consume when they drink water or not since sugar-sweetened beverages are often used as a replacement for water. SSB intake has been falling among children over the last 15 years, but there are still pockets and sub-populations that have high consumption levels. It is critical to identify which kids are particularly at risk for high SSB intake since this can lead to these negative health effects. Overall we found that kids that did not consume any plain water (from tap or bottled water) consumed almost twice as many calories and percent of total calories from sugar-sweetened beverages than kids that consumed water. And for the sample overall that translated to nearly 100 extra calories on a given day. 
Author Interviews, Diabetes, Weight Research / 23.04.2019

MedicalResearch.com Interview with: Kishore M. Gadde, MD, Professor Fairfax Foster Bailey Endowed Chair in Heart Disease Prevention Medical Director, Clinical Services Pennington Biomedical Research Centre Baton Rouge, LA 70808  MedicalResearch.com: What is the background for this study? Response: Around 20 years ago, the Diabetes Prevention Program, DPP, enrolled 3,234 adults with excess body weight and impaired glucose tolerance. The idea was to compare the efficacy of either an intensive lifestyle intervention or metformin relative to placebo in preventing diabetes. Over approximately 3 years, both lifestyle and metformin were effective, but lifestyle intervention was better for weight loss as well as in reducing the risk of diabetes. After the blinded treatment phase ended, the researchers continued to follow this cohort in their originally randomised groups.

Baker, MPH, MA Centennial Scholar PhD Candidate Health Policy Research Scholar Department of Health Policy and Management Johns Hopkins Bloomberg School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study shows that transgender adults in the U.S. today have significantly worse health-related quality of life than cisgender (non-transgender) adults, as measured by self-reported health status and number of recent days of poor physical or mental health. The study is important because it quantifies the gap in health-related quality of life between transgender and cisgender people, and it relies on a survey that allows us to believe that these findings are likely true not just for the people who answered the survey but for the U.S. as a whole. Health-related quality of life is a very broad term that describes a person’s whole sense of well-being—we might think of it as the answer to the question, “how are you doing these days?” The answer has to do not just with your physical health but also your mental health, your outlook on your life and your community, your feelings of wholeness and happiness. Sources such as the National Academy of Medicine and the U.S. Transgender Survey have documented that transgender people face discrimination in areas of everyday life such as housing, health care, and public spaces. Encounters with discrimination don’t just keep transgender people from getting services they need: they hurt trans people both physically and mentally. 
Author Interviews, Cost of Health Care, Radiation Therapy / 23.04.2019

MedicalResearch.com Interview with: [caption id="attachment_48748" align="alignleft" width="133"]Ankit Agarwal, MD, MBAPGY-3, Radiation Oncology ResidentUNC Health Care Dr. Agarwal[/caption] Ankit Agarwal, MD, MBA PGY-3, Radiation Oncology Resident UNC Health Care MedicalResearch.com: What is the background for this study? What are the main findings? Response: Medicaid provides vital health insurance for millions of mostly low income Americans throughout the United States. However, it is well known that patients with Medicaid have worse clinical outcomes than patients with private insurance or Medicare insurance. Part of the reason for this may be due to difficulties with access to care, in part due to the traditionally very low payments in the Medicaid system. We found that Medicaid payment rates for a standard course of breast cancer radiation treatment can vary over fivefold (ranging from $2,945 to $15,218)
