MedicalResearch.com Interview with: [caption id="attachment_48770" align="alignleft" width="200"]Alexa B. Erck Lambert, MPHDB Consulting Group, Inc, Silver Spring, MarylandCenters for Disease Control and Prevention, Contractor Dr. Erck Lambert[/caption] Alexa B. Erck Lambert, MPH DB Consulting Group, Inc, Silver Spring, Maryland Centers for Disease Control and Prevention Contractor  MedicalResearch.com: What is the background for this study? 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, MACentennial Scholar PhD CandidateHealth Policy Research ScholarDepartment of Health Policy and ManagementJohns Hopkins Bloomberg School of Public Health Kellan Baker[/caption] Kellan E. 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.

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)

Littauer Professor Chair of the Department of Psychiatry NYU Langone School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Several studies in recent years have attempted to identify biological markers that distinguish individuals with PTSD, with candidate markers including changes in brain cell networks, genetics, neurochemistry, immune functioning, and psychophysiology. Despite such advances, the use of biomarkers for diagnosing PTSD remained elusive going into the current study, and no physical marker was applied in the clinic. Our study is the first to compare speech in an age and gender matched sample of a military population with and without PTSD, in which PTSD was assessed by a clinician, and in which all patients did not have a major depressive disorder. Because measuring voice qualities in non-invasive, inexpensive and might be done over the phone, many labs have sought to design speech-based diagnostic tools

What are the main findings?  Response: Previous findings from randomized controlled trials evaluating the effects of red meat on cardiovascular disease risk factors have been inconsistent. But our new study, which makes specific comparisons between diets high in red meat versus diets high in other types of foods, shows that substituting red meat with high-quality protein sources lead to more favorable changes in cardiovascular risk factors. That is, to properly understand the health effects of red meat, it’s important to pay attention to the comparison diet. People do not simply eat more or less meat – it will almost always be in substitution with other foods.

Nfonsam, MD, MS, FACS Associate Professor of Surgery Program Director, General Surgery Residency Colon and Rectal Surgery Division of Surgical Oncology University of Arizona, Tucson  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The overall incidence of colon cancer in the United states has gone down in the last few decades. However, there has been a significant increase in the incidence of sporadic colon cancer is young patients (<50 years old). The etiology of this phenomenon is likely multi-factorial. These young patients do present with more advanced disease and with aggressive features. We demonstrated in our study that the colon cancer tumor biology was different between young and older patients. We also singled out a particular gene, Cartilage oligomeric Matrix Protein (COMP) which was significantly over-expressed in young patients and demonstrated its role in cancer proliferation and metastasis and also its potential as a prognostic biomarker since we were able to detect it in plasma.

MedicalResearch.com Interview with: [caption id="attachment_48672" align="alignleft" width="149"]Madhav P. Bhatta, PhD, MPHAssociate Professor, Epidemiology & Global HealthCollege of Public HealthKent State UniversityKent, OH 44242 Dr. Bhatta[/caption] Madhav P. Bhatta, PhD, MPH Associate Professor, Epidemiology & Global Health College of Public Health Kent State University Kent, OH 44242 MedicalResearch.com: What is the background for this study? Response: Lead exposure, especially in children, in any amount is harmful. Lead poisoning is a growing global environmental health problem with increasing lead-related diseases, disabilities, and deaths.  While exposure to lead in US children, in general, has significantly declined in the last three to four decades certain sub-groups of US children such as African Americans, immigrants and resettled refugees, and those from lower socioeconomic backgrounds are still vulnerable to environmental lead exposure. Previous studies among resettled refugee children in the United States had found 4- to 5-times higher prevalence of elevated blood lead level (EBLL) when compared to US-born children. However, most of the studies were conducted when EBLL was defined as blood lead level ≥ 10 µg/dL. In 2012, the US Centers for Disease Control and Prevention changed the reference value for EBLL to ≥ 5 µg/dL. Moreover, because the countries of origin for US resettled refugees change over time, it is important to have epidemiologic studies that provide the current information on EBLL among these vulnerable new US immigrant children. Using blood lead level data from the post-resettlement medical screening, our study examined the prevalence of elevated blood lead level at the time of resettlement among former refugee children who were settled in the state of Ohio from 2009-2016. We had a large and diverse sample (5,661 children from 46 countries of origin) of children for the study, which allowed us to assess EBLL in children from several countries of origin that had not been previously studied.

What are the main findings? Response: Exposure to lead is dangerous and has been banned from use in residential dwellings. However, residual sources of lead still exist. Few studies have examined pediatric lead poisoning between public (NYCHA) and private housing units, and no recent studies performed in New York City. Our study used retrospective chart analysis of routine child lead testing to examine the difference in blood lead levels between the two housing types. Our data showed that children seen in our health centers who lived in New York City public housing had significantly lower mean blood lead levels and fewer children were found with levels over the CDC reference range of 5 μg/dL compared to children who lived in private housing.

Emeritus Research Professor Inserm University Paris Diderot Acticor Biotech Hôpital Bichat France  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Blood platelets are key actors in thrombosis a leading cause of global mortality estimated to account for 1 in 4 death worldwide in 2010. Thrombosis is associated with cardiovascular diseases (myocardial infarction, stroke, lower limb ischemia, venous thromboembolism), and with numerous pathologies such as cancer, infections or inflammatory diseases. Currently available antiplatelet drugs are the cornerstone of therapy for patients with acute coronary syndromes. However, these drugs all carry an inherent risk of bleeding that restricts their use in sensitive populations and when arterial thrombosis occurs in the cerebral territory. At present the only acute treatment option available for ischemic stroke consists in revascularization by thrombolysis, and/or mechanical thrombectomy. But the number of patients eligible to these treatments is low (» 15% of all patients) and the success rate does not exceed 50%. The responsibility of platelets in the failure for thrombolysis / thrombectomy to restore vascular patency is strongly suspected. There is thus a clear medical need for new antiplatelet drugs with an improved safety profile. We set out to develop ACT017, a novel, first in class, therapeutic antibody to platelet glycoprotein VI with potent and selective antiplatelet effects. The interest of GPVI resides in the fact that it's a receptor involved in the development of occlusive thrombi but that it is not strictly required for physiological hemostasis.

  • Lung cancer remains the most common cancer, and leading cause of cancer mortality, in the world and ~40-50% of lung cancer patients will need radiation therapy as part of their care
  • The accuracy and precision of lung tumor targeting by radiation oncologists can directly impact outcomes, since this key targeting task is critical for successful therapeutic radiation delivery.
  • An incorrectly delineated tumor may lead to inadequate dose at tumor margins during radiation therapy, which in turn decreases the likelihood of tumor control.
  • Multiple studies have shown significant inter-observer variation in tumor target design, even among expert radiation oncologists
  • Expertise in targeting lung tumors for radiation therapy may not be available to under-resourced health care settings

MedicalResearch.com Interview with: Eugene Chan, PhD Senior Lecturer in Marketing Monash Business School Monash University Australia and  Sam Maglio PhD Associate Professor of Marketing Department of Management University of Toronto  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The physiological effects of coffee and caffeine consumption have been well-studied, but we were interested in the psychological effects. Especially in Western societies, there is a mental association between coffee and arousal – that coffee is an arousing beverage. This led us to ask, might this association itself produce the psychological “lift” without actually drinking beverages? We found that it does. Merely seeing pictures of coffee or thinking about coffee can increase arousal, heart rates, and make people more focused. The effects are not as strong as actually drinking coffee of course, but they are still noticeable.

What are the main findings?  Response: People have been using nicotine replacement therapy, otherwise known as NRT, to quit smoking for more than 20 years. NRT is available in a range of forms: skin patches, chewing gum, nasal and oral sprays, inhalators, and lozenges. We have good evidence that it is safe and that it helps more people to quit than trying to stop smoking using no medication. We carried out a systematic review to try and find out what the best ways are to use NRT to maximise a person’s chances of quitting successfully. We did this by looking at studies that compared at least two different types of NRT use, such as higher versus lower doses, or longer versus shorter use. The takeaway message from the review is that using more nicotine (in the form of nicotine replacement therapy, ) to aid quitting can help more people to stop smoking in the long-term. There is high quality evidence that using two forms of nicotine replacement at the same time – a patch as well as a faster-acting form such as gum - increases chances of quitting, and evidence also suggests that starting to use nicotine replacement before the day you give up cigarettes can help more people quit than beginning use on the day you stop. There is no evidence that using more nicotine replacement is harmful when used as directed.

Our study aimed to examine whether these findings would be applicable in a real-world setting (i.e., outside of research). We found that peanut oral immunotherapy is safe in the vast majority of preschoolers, with only 0.4% of patients experiencing a severe reaction, and only 12 out of ~40,000 peanut doses needed epinephrine (0.03%).

Atlanta, GA 30303  MedicalResearch.com: What is the background for this study? Response: Despite a continuous decline in cervical cancer incidence rates, earlier studies reported an increase in cervical adenocarcinoma incidence rates. However, those reports had major limitations, as they did not account for changes in hysterectomy prevalence and used cancer occurrence data covering only 10%-12% of the U.S. population (which may not be representative of the entire population, especially racial/ethnic minorities). Further, the most recent study examined the trends by age and histology through 2010. We examined contemporary trends in cervical cancer incidence rates in the U.S. (1999-2015) by age, race/ethnicity, major histological subtypes, and stage at diagnosis using up-to-date nationwide data after accounting for hysterectomy prevalence.

MedicalResearch.com Interview with: [caption id="attachment_48691" align="alignleft" width="200"]Dr-Elsa F. Fouragnan Dr. Fouragnan[/caption] Elsa F. Fouragnan PhD School of Psychology (Faculty of Health and Human Sciences) University of Plymouth MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Counterfactual thinking is a psychological process that involves the tendency to create possible alternatives to life events that are currently happening. It is very important because it gives us the ability to switch away from uninteresting activities if better ones become available. For example, if you are working or doing the housework, you may be thinking about gardening or watching a movie later. As soon as your duties are finished, you may engage in these more exciting activities. In our study, macaque monkeys were tasked to find treats under several colored cups (on a screen). Some of these cups were better than others but were not always available, thus the animals had to retain what they had learnt about the good cups in case they became available again. We found that a frontal part of the brain called the anterior cingulate cortex was responsible for tracking which cups were the best in order to efficiently switch to them if the opportunity arose. If this part of the brain was not functioning properly, then animals were stuck in non-optimal choices. To reveal the causal role of the anterior cingulate cortex, we used a new neurostimulation method called low-intensity repetitive ultrasound to modulates activity in this part of the brain with millimetre accuracy.

What are the main findings? Response: The search for markers of aggression during childhood is a particularly relevant area of research, since the results of intervention and prevention during this developmental stage are more promising than those obtained during later stages. The psychobiological approach to aggressive behavior is of particular importance, as it analyzes the joint, interactive influence of both psychological and biological variables. We have found that there are different interactions on a biological and psychological level that could account for aggressive behavior in children. More deeply, empathy and hormones could together account for aggressive behavior. In fact, the interactions were different for boys and for girls.

Response: DNA genetic testing (DGT) for hereditary cancer genes is now a well accepted clinical practice; however, the interpretation of DNA variation remains a challenge to laboratories and medical providers. RNA genetic testing (RGT) as a supplement to DGT is a means to clarify the clinical actionability of variants in hereditary cancer genes, improving our ability to accurately apply known strategies for cancer risk reduction.

The results were presented at the American Association of Neurological Surgeons (AANS), April 2019 MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Traumatic brain injury (TBI) is a major cause of death and disability in the US and around the globe. The effects of TBI are often long-lasting, with more than one-third of severe TBI patients displaying a neuromotor abnormality on physical examination 2 years following injury and, yet, there are no effective treatments. The public health implications are staggering: there are approximately 1.4 million new cases of TBI in the US annually, resulting in over 50,000 deaths and 80,000 disabilities; over 5 million Americans currently suffer from long-term disability caused by TBI. A successful neuroregenerative or neurorestorative therapy, such as stem cell implantation, would have significant impact.

Cohen, M.D., Ph.D., Senior Investigator Marlene Bönstrup, M.D., Postdoctoral fellow in  Dr. Cohen's lab NIH's National Institute of Neurological Disorders and Stroke MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Learning a new skill is typically divided into online (during practice) and offline (after practice has ended) components. Particularly motor skill learning occurs to a considerable degree offline, meaning that performance further improves even after practice has ended. A single practice session itself however, is typically divided into short (level of seconds) periods of practice and rest. In this study, we set out to investigate the contribution of those short periods of practice and rest to the learning during a practice session (i.e. online learning). We found that during early motor skill learning, when most of the total learning occurs, performance improvements actually precipitate during short periods of rest whereas during practice periods, performance mostly stagnated. We found a signature of neural activity predictive of those performance improvements during rest: The lower the beta rhythmic activity in the parietofrontal regions of the brain during those short periods of rest, the higher were participant’s performance jumps.

In addition, there have been indications that different protein sources have differential associations with mortality risk.  Thus, we investigated the associations of proteins and protein sources with mortality risk in the Finnish men of the Kuopio Ischaemic Heart Disease Risk Factor Study.

What are the main findings? Response: Although hypercholesterolemia is a risk factor for ischemic stroke, some prior studies have observed an inverse association between total and low-density lipoprotein (LDL) cholesterol and risk of hemorrhagic stroke.  However, many studies were not able to study this association specifically among women. Our main result was very low levels of low-density lipoprotein (LDL) cholesterol or low levels of triglycerides were associated with an increased risk of hemorrhagic stroke among women.

What are the main findings?  Response: College students engage in activities such as binge drinking, abuse of ADHD medications as "study drugs" or use of illicit drugs during a critical brain developmental window that supports maturation of the brain (the prefrontal cortex) necessary for emotional control, cognitive functions and regulation of impulsive behaviors. These activities not only affect brain function, thus mental health and cognitive functions, but may dampen brain development with potential long-lasting effects. As for findings, we were able to identify neurobehavioral patterns that associate with mental wellbeing and mental distress in young adults. Based on evidence from the literature, we constructed conceptual models that describe how one behavior may lead to another until virtuous or vicious cycles set-in.

MedicalResearch.com Interview with: [caption id="attachment_48633" align="alignleft" width="200"]Lauren Gaydosh, PhDAssistant ProfessorCenter for Medicine, Health, and SocietyPublic Policy StudiesVanderbilt University  Dr. Gaydosh[/caption] Lauren Gaydosh, PhD Assistant Professor Center for Medicine, Health, and Society Public Policy Studies Vanderbilt University  MedicalResearch.com: What is the background for this study?   Response: Several years ago, life expectancy at birth in the United States declined, and this decline has continued every year since. Part of the cause underlying this decline is that midlife mortality – deaths among those 45-54 – has been rising. This increase in midlife mortality has been attributed by some to the “deaths of despair” – a cluster of causes of death including suicide, drug overdose, and alcohol-related disease - and has been most pronounced among middle-aged white adults with a HS degree or less. In our research, we wanted to better understand the indicators of despair that would be predictive of these causes of death. Things like depression, substance use, and suicidal ideation. And study them in individuals before the period of elevated risk of death – in other words, before they reached middle age. Our goal was to evaluate whether these markers of despair were rising for a younger cohort, and whether this pattern was isolated to white adults with low education.
