MedicalResearch.com Interview with: Sean C. Rose, MD Pediatric sports neurologist and co-director Complex Concussion Clinic Nationwide Children’s Hospital Assistant professor of Pediatrics The Ohio State UniversitySean C. Rose, MD Pediatric sports neurologist and co-director Complex Concussion Clinic Nationwide Children’s Hospital Assistant professor of Pediatrics The Ohio State University MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The link between sub-concussive head impacts and declines in neurocognitive function has been reported by some studies, yet refuted by others.  There is very little evidence that has been collected in children as they are sustaining these head impacts. We initiated a multi-year study of youth football players to provide a more in-depth look at the question.  We measured head impacts using helmet sensors during the 2016 football season.  112 players age 9-18 completed a battery of neurocognitive tests before and after the football season. We found that neither the total burden of head impacts nor the intensity of individual impacts were associated with changes in testing performance from pre to post-season. (more…)
Author Interviews, JAMA, Opiods, Pediatrics / 26.10.2018

MedicalResearch.com Interview with: Joshua Barocas, MD Assistant Professor of Medicine Section of Infectious Diseases Boston Medical Center / Boston University School of Medicine Joshua Barocas, MD Assistant Professor of Medicine Section of Infectious Diseases Boston Medical Center / Boston University School of Medicine  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Massachusetts has been particularly hard hit by the opioid epidemic despite lower opioid prescribing rates, near universal health insurance, and availability of opioid treatment. That said, it is difficult to estimate the population with or at-risk for opioid use disorder. It is generally a highly stigmatized disease and typical methods to estimate of opioid use disorder relay on contact with the healthcare system and/or patient reporting. We used a unique and powerful methodology coupled with a first-in-the-nation linked database in Massachusetts to obtain both an accurate count of people with opioid use disorder who are known to the healthcare system and estimate the number who are out there but not yet known to the system. We found that more than 275,000 people – or 4.6 percent of people over the age of 11 in Massachusetts– have opioid use disorder, a figure nearly four times higher than previous estimates based on national data. In 2011 and 2012, the prevalence of opioid use disorder in Massachusetts for those over the age of 11 was 2.72 percent and 2.87 percent, respectively. That increased to 3.87 percent in 2013, and even more, to 4.6 percent in 2015. Those between the ages of 11 and 25 experienced the greatest increase in prevalence of all age groups. The number of “known” persons increased throughout the study period – from 63,989 in 2011 to 75,431 in 2012, and 93,878 in 2013 to 119,160 in 2015.  (more…)
Accidents & Violence, Author Interviews, Pediatrics / 25.10.2018

MedicalResearch.com Interview with: Gary A. Smith, MD, DrPH Director, Center for Injury Research and Policy Nationwide Children’s Hospital Columbus, OH MedicalResearch.com: What is the background for this study? Response: When residential fires happen at night while people are sleeping, deaths are more likely to occur. Smoke alarms are important for preventing these deaths, yet many young children don’t wake up to traditional high-pitch tone alarms. Children sleep longer and deeper than adults and require louder sounds to awaken than adults. For these reasons, children are less likely to awaken and escape a nighttime home fire. (more…)
Author Interviews, Pediatrics, Stanford, Surgical Research, Weight Research / 22.10.2018

MedicalResearch.com Interview with: Dr. Janey Pratt, MD Clinical Associate Professor, Surgery Stanford UniversityDr. Janey Pratt, MD Clinical Associate Professor, Surgery Stanford University MedicalResearch.com: What is the background for this study? What are the main findings? Response: In 2013 obesity became recognized as a disease.  The rate of pediatric obesity continues to rise.  Severe pediatric obesity is rising at a even faster rate than obesity in pediatrics.  Despite this Metabolic and Bariatric Surgery (MBS) remains underutilized in the treatment of severe pediatric obesity.  There is a significant amount of adult data and now pediatric data about effective treatments for severe obesity.  These support the use of MBS as a primary treatment for severe obesity in children. (BMI > 120% of 95th percentile with a comorbidity or BMI > 140% of 95th percentile). (more…)
Author Interviews, Nutrition, OBGYNE, Pediatrics, Race/Ethnic Diversity / 19.10.2018

MedicalResearch.com Interview with: "Tortillas di una miscela di mais azzurro tostato" by fugzu is licensed under CC BY 2.0Vijaya Kancherla, PhD Research Assistant Professor, Department of Epidemiology Epidemiologist, Center for Spina Bifida Prevention Rollins School of Public Health Emory University Atlanta GA 30322 MedicalResearch.com: What is the background for this study?  Response: The scientific evidence since 1991 has shown that folic acid prevents from 35%-95% of neural tube birth defects that are caused due to low folic acid (also known as vitamin B9) in the mother’s diet prior to conception and during early pregnancy. Neural tube defects form in the embryo at 4th week of gestation when most women are unaware they are pregnant. Taking any amount of folic acid after the 4th week of pregnancy will not prevent neural tube defects. There is no cure for these birth defects. So, it matters for women to have enough folic acid prior to conception and in the first four weeks of pregnancy. If a woman is not taking prenatal vitamins that early, folic acid fortified foods come to rescue. Foods fortified with folic acid will prevent folate deficiency for everyone, and offer the benefit to mothers who were not planning their pregnancies or were not taking folic acid pills. If corn masa flour and tortillas were fortified with folic acid, that would help millions of reproductive aged women have healthy stores of folic acid in their bodies, to prepare them for their pregnancy, irrespective of their pregnancy plans. Prior to April 2016, folic acid (also known as vitamin B9) was not allowed to be added to corn masa flour (or products made from masa such as tortillas and tortilla chips) in the US. So, there was no expectation of having folic acid in these products. The March of Dimes, Spina Bifida Foundation, the American Academy of Pediatricians, Gruma Corporation and others filed a petition with the US FDA and succeeded in allowing millers to voluntarily add folic acid to corn masa flour and tortillas as a food additive. This regulation was implemented by the US FDA in April 2016.  (more…)
Author Interviews, CDC, Pediatrics, Vaccine Studies, Vanderbilt / 18.10.2018

MedicalResearch.com Interview with: "Vacuna influenza / Flu vaccine" by El Alvi is licensed under CC BY 2.0Kathryn M. Edwards, M.D. Sarah H. Sell and Cornelius Vanderbilt Chair in Pediatrics Professor of Pediatrics Vanderbilt University School of Medicine Dr. Edwards discusses the statement from the Infectious Diseases Society of America (IDSA) regarding the Centers for Disease Control and Prevention’s new data on child vaccine rates across the United States. MedicalResearch.com: What is the background for this study? What are the main findings? Response: To monitor the uptake of vaccines the CDC conducts a National Immunization Survey each year.  This survey is conducted by random-digit dialing (cell phones or landlines) of parents and guardians of children 19-35 months of age.  The interviewers ask the families who provides the vaccines for their children and if these providers can be contacted to inquire about the immunizations received.  The overall response rate to the telephone survey was 26% and immunization records were provided on 54% of the children where permission was granted.  Overall 15, 333 children had their immunization records reviewed. When comparing immunization rates for 2017 and 2016, the last two years of the study, several new findings were discovered. First the overall coverage rate for 3 doses of polio vaccine, one dose of MMR, 3 doses of Hepatitis b, and 1 dose of chickenpox vaccine was 90%, a high rate of coverage.  Children were less likely to be up to date on the hepatitis A vaccine (70%) and rotavirus vaccine (73%). Coverage was lower for children living in rural areas when compared with urban areas and children living in rural areas had higher percentages of no vaccine receipt at all (1.9%) compared with those living in urban areas (1%). There were more uninsured children in 2017 at 2.8% and these children had lower immunization rates.  In fact 7.1% of the children with no insurance were totally unimmunized when compared with 0.8% unimmunized in those with private insurance. Vaccine coverage varies by state and by vaccine. (more…)

MedicalResearch.com Interview with: Dr. Linda Ewing-Cobbs PhD Professor in the Department of Pediatrics McGovern Medical School University of Texas Health Science Center at Houston Harriet and Joe Foster Chair in Cognitive Neuroscience MedicalResearch.com: What is the background for this study? What are the main findings? Response: Children may have long-lasting psychological and physical symptoms after an injury. Post-concussive symptoms (PCS) are nonspecific cognitive, physical, and mood symptoms such as difficulty concentrating, headache, and irritability. These symptoms occur in approximately 15 to 30% children after mild traumatic brain injury (TBI). Although PCS often resolve within one month, some children experience symptoms for longer periods of time. (more…)
Author Interviews, BMJ, Genetic Research, Pain Research, Pediatrics / 17.10.2018

MedicalResearch.com Interview with: "DNA model" by Caroline Davis2010 is licensed under CC BY 2.0Hakon Hakonarson, MD, PhD Corresponding Author Xiao Chang, PhD Lead Author The Center for Applied Genomics Children’s Hospital Philadelphia Philadelphia, Pennsylvania MedicalResearch.com: What is the background for this study? What are the main findings? Response: Migraine is a genetic disorder characterized by recurrent and intense headaches often accompanied by visual disturbances. Genome-wide association studies (GWASs) are a powerful hypothesis-free tool for investigating the genetic architecture of human disease. Currently, multiple GWASs have been conducted on European adults with migraine that have successfully identified several migraine susceptibility genes involved in neuronal and vascular functions. Considering the prevalence of migraines varies across ethnicities, the genetic risk factors may be different in patients of African ancestries and European ancestries. In addition, if migraine presents at an early age (childhood), it may reflect elevated biological predisposition from genetic factors or increased susceptibility to environmental risk factors. We performed the first GWAS to investigate the susceptibility genes associated with migraine in African-American children. The main out come was that common variants at the 5q33.1 locus in the human genome are associated with migraine risk in African-American children. The genetic underpinnings at this locus responsible for this finding are less relevant in patients of European ancestry.  (more…)
Author Interviews, CDC, JAMA, Pediatrics, Smoking / 04.10.2018

MedicalResearch.com Interview with: "Electronic Cigarette/E-Cigs/E-Cigarettes" by Chris F is licensed under CC BY 2.0Brian King, PhD Lead author and Deputy Director for Research Translation Office on Smoking and Health. CDC MedicalResearch.com: What is the background for this study? Response: Since first entering the U.S. marketplace in 2007, e-cigarettes have been a rapidly evolving product class. Typically, national surveys provide annual, self-reported estimates of e-cigarette use among adults and youth. However, given the dynamic nature of the e-cigarettes landscape, data collected at a sub-annual level can be useful for identifying rapid changes and patterns. For example, retail sales data, which is available at more frequent intervals, such as weekly, can complement annual surveys and help keep a pulse on emerging trends. This study assessed e-cigarette retail sales data in the United States from 2013 through 2017. (more…)
Author Interviews, Pediatrics, Sexual Health / 02.10.2018

MedicalResearch.com Interview with: Laura M. Padilla-Walker, PhD Professor, School of Family Life Associate Dean, College of Family, Home, and Social Sciences Brigham Young University MedicalResearch.com: What is the background for this study? What are the main findings? Response: The current study included approximately 500 teens that we followed for 8 years starting at approximately age 14. In this particular study, we explored how parent-child sex communication regarding sexual safety changed from ages 14-18, and then how this change was associated with children’s sexual outcomes at age 21. Though we would hope and expect that parents would discuss sexual safety with their children at increasing levels as children age, findings from this study suggested low and unchanging levels of parent-child sex communication over time. In other words, parents are talking very little to their children about sexual safety, and how much they talk to children isn’t changing from age 14 to 18. In addition, mothers reported significantly higher levels of sex communication than did children and fathers, suggesting that mothers think they talk about sexuality more than children think they do. Though this is an issue of perception, what the child perceives is generally a more important predictor of positive outcomes. Mothers also reported talking with their sons less than their daughters, though sex communication with sons increased over time and by age 18 mothers reported the same (relatively low) levels of sex communication with both daughters and sons. That being said, initial levels and positive change in parent-child sex communication was associated with safer sex at age 21, suggesting that parents SHOULD talk with their children more and at increasing levels over time, because these factors are associated with positive child outcomes.

Author Interviews, Brigham & Women's - Harvard, JAMA, Pediatrics / 01.10.2018

MedicalResearch.com Interview with: Matthew D. Weaver, PhD Instructor in Medicine · Harvard Medical School Associate Epidemiologist · Division of Sleep and Circadian Disorders Brigham and Women's Hospital Boston, MA 02215 MedicalResearch.com: What is the background for this study? Response: We were interested whether high school students who tended to sleep less than 8 hours per night reported more risk-taking behaviors compared to high school students who slept at least 8 hours per night on a school night. We utilized a nationally representative dataset from the CDC of surveys that were completed by high school students between 2007 and 2015. Over that time, approximately 67,000 students were surveyed. Students were asked about the hours of sleep that they obtained on an average school night. They were also asked how often, in the month prior to the survey, they engaged in a number of risk-taking behaviors. Some behaviors were related to driving, like driving without a seatbelt or driving drunk, while others were related to using alcohol, doing drugs, or being involved in a fight. They were also asked about their mood, including whether they felt sad or hopeless, considered suicide, and whether they had attempted suicide.  (more…)
Author Interviews, Genetic Research, Pediatrics / 28.09.2018

MedicalResearch.com Interview with: Barry M. Lester, PhD Center for the Study of Children at Risk Warren Alpert Medical School, Brown University Women and Infants Hospital of Rhode Island Providence, Rhode Island;  MedicalResearch.com: What is the background for this study? What are the main findings? Response: We know from rodent studies that maternal care or nurturing behavior can change the rat pups physiologic response to stress. More nurturing behavior makes it easier for rat pups to relax after stress. Not only that, these changes are permanent, they last into adulthood and there is evidence that these changes can be passed on to the next generation. With animal studies you can unlock the mechanism for this in ways that you can’t do with humans and we know from the rodent studies that the mechanism for these changes has to do with changes in gene activity. Nurturing behavior controls a specific gene that regulates the infant’s physiological response to stress. In other words, we are looking at maternal behavioral programming of a gene that can make, in our case, a human infant less physiologically reactive to stress. The physiological reactivity to stress that we studied was the production of the stress hormone cortisol. Cortisol is part of the body’s flight or fight reaction, the body’s major response to stress and too much or too little cortisol can be harmful and is related to a wide range of mental and physical health disorders in children and adults. The concerns about separating immigrant children from their parents that we read about every day in the paper are based on this same physiological system, where brain structures that control cortisol production are damaged by the stress of separation.  (more…)

MedicalResearch.com Interview with: Dr. Marcus Smith PhD Reader in Sport and Exercise Physiology University of Chichester Co-founder, Clem Burke Drumming ProjectDr. Marcus Smith PhD Reader in Sport and Exercise Physiology University of Chichester Co-founder, Clem Burke Drumming Project MedicalResearch.com: What is the background for this study? Response: The research group first started to examine rock drumming from a scientific perspective in 1999 through collaboration with Clem Burke, drummer with the iconic band ‘Blondie’. In 2008 the Clem Burke Drumming Project (CBDP) was formed (visit clemburkedrummingproject.org for further information) where academics from different disciplines came together to not only explore the physiological demands of rock drumming but also the potential use of rock drumming as an intervention in research studies. Rock drumming is attractive to the scientist in that it is a unique activity that requires the coordination of multiple limbs to produce the required drumming pattern. Inherent demands relating to timing, tempo and volume must also be met. Therefore, the ability to manipulate these facets of drumming performance in a research setting is very appealing. In relation to potential research populations drumming has a universal fascination regardless of age, gender, culture, language competency and ethnicity. Anecdotal evidence suggests that drumming is a ‘cool’ activity that has a unique ‘language currency’ in terms of stimulating communication within and between those who can and cannot play the drums. The impetus for our research study came from parents of autistic children contacting us to express their belief that drumming was having a positive effect on their child’s physical and psychological behaviour. A review of the literature showed a range of anecdotal evidence in support of such statements (Freidman 2000) and an increase in empirical drumming based research being undertaken (Bungay 2010). More recent studies have reported psychosocial benefits such as enhanced communication (Maschi et al. 2010; 2012), emotional processing and tension reduction (Flores et al. 2016; Maschi et al. 2010; 2012), group cohesion and connectedness (Blackett et al. 2005), concentration, psychomotor coordination and posture (Chen et al. 2017). The majority of this work was undertaken with adolescents with very little work focused on younger age groups. (more…)

MedicalResearch.com Interview with: Michelle M Johns, MPH, PhD Health Scientist Division of Adolescent and School Health CDC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Gender nonconformity is an under-researched area of adolescent health that is often linked to negative health outcomes. To address this gap, we analyzed Youth Risk Behavior Survey data to describe the associations between gender nonconformity and risk behaviors, including mental distress, and substance use. Gender nonconformity was associated with feeling sad and hopeless, as well as suicidal thoughts and/or behaviors among female and male students. In addition, gender nonconformity was strongly associated with substance use among male students. (more…)
Author Interviews, Brain Injury, CT Scanning, Emergency Care, JAMA, Pediatrics / 24.09.2018

MedicalResearch.com Interview with: Erik P. Hess MD MSc Professor and Vice Chair for Research Department of Emergency Medicine UAB Medicine he University of Alabama at Birmingham Birmingham Alabama 35249 MedicalResearch.com: What is the background for this study? What are the main findings?  Response: 450,000 children present to U.S emergency departments each year for evaluation of head trauma.  Physicians obtain head computed tomography (CT) scans in 37%-50% of these patients, with less than 10% showing evidence of traumatic brain injury and only 0.2% that require neurosurgical treatment. In order to avoid unnecessary CT scans and to limit radiation exposure, the Pediatric Emergency Care Applied Research Network (PECARN) developed clinical prediction rules that consist of 6 readily available factors that can be assessed from the history and physical examination.  If none of these risk factors are present, a CT scan is not indicated. If either of 2 high risk factors such as signs of a skull fracture are present, CT scanning is indicated. If 1 or 2 non-high risk factors are present, then either CT scanning or observation are recommended, depending on considerations such as parental preference, clinician experience and/or symptom progression. In this study we designed a parent decision aid, “Head CT Choice” to educate the parent about the difference between a concussion – which does not show up on a CT scan – and a more serious brain injury causing bleeding in or around the brain.  The decision aid also shows parents their child’s risk for a serious brain injury – less than 1% risk in the majority of patients in our trial – what to observe their child at home for should they opt not to obtain a CT scan, and the advantages and disadvantages of CT scanning versus home observation. In our trial, we did not observe a difference in the rate of head CT scans obtained in the ED but did find that parents who were engaged in shared decision-making using Head CT Choice were more knowledgeable about their child’s risk for serious brain injury, has less difficulty making the decision because they were clearer about the advantages and disadvantages of the diagnostic options, and were more involved in decision-making by their physician.  Parents also less frequently sought additional testing for their child within 1 week of the emergency department visit.

Author Interviews, Endocrinology, Pediatrics, Race/Ethnic Diversity / 23.09.2018

MedicalResearch.com Interview with: Julie Flom, MD MPH Clinical Fellow Division of Allergy & Immunology Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study?   Response: Women who are minorities and of lower socioeconomic have particularly high rates of exposure to chronic ongoing adversity such as poverty as well as traumatic stressors in their lifetime and are also more likely to have low birthweight infants.  Not all women exposed to chronic adversity or trauma transfer this risk to the next generation – it is primarily when the trauma results in changes in her bodies’ ability to handle ongoing stress that the developing child can be impacted. Our group undertook a study to investigate whether women with increased exposure to traumatic stressors over her lifetime were at higher risk of having low birthweight infants and also whether effects of trauma would only be evident among women who produced higher levels of cortisol, the major stress response hormone, while pregnant.

MedicalResearch.com Interview with: Eyal Cohen, MD, MSc, FRCP(C) Associate Scientist and Program Head (interim), Child Health Evaluative Sciences Research Institute, The Hospital for Sick Children Staff Physician, Division of Paediatric Medicine, The Hospital for Sick Children Professor, Paediatrics and Health Policy Management & Evaluation The University of Toronto MedicalResearch.com: What is the background for this study? What are the main findings? Response: Having a child with a major birth defect can be a life-changing and stressful event for the child's mother.  This stress may be associated with higher risk of premature cardiovascular disease. We found that mothers of infants born with a major birth defect had a 15% higher risk of premature cardiovascular disease that a comparison group of mothers.  The risk was more pronounced, rising to 37% among mothers who gave birth to a more severely affected infant (and infant born with major birth defects affecting more than one organ system). The risk was apparent even within the first 10 years after the birth of the child.

Author Interviews, Diabetes, Gluten, Lancet, OBGYNE, Pediatrics / 21.09.2018

MedicalResearch.com Interview with: Knud Josefsen, senior researcher Bartholin Institute, Rigshospitalet, Copenhagen K, Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Response: In a large population of pregnant women, we found that the risk of the offspring being diagnosed with type 1 diabetes before the age of 15.6 years (the follow up period) was doubled in the group of women ingesting the highest amounts of gluten (20-66 g/day) versus the group of women ingesting the lowest amounts of gluten (0-7 g/day). For every additional 10 grams of gluten ingested, the risk for type 1 diabetes in the child increased by a factor of 1.31. It the sense that it was a hypothesis that we specifically tested, we were not surprised. We had seen in animal experiments that a gluten-free diet during pregnancy protected the offspring from diabetes, and we wanted to see if we could prove the same pattern in humans. There could be many reasons why we would not be able to show the association, even if it was there (sample size, low quality data, covariates we could not correct for and so on), but we were off course pleasantly surprised that we found the association that we were looking for, in particular because it is quite robust (more…)

MedicalResearch.com Interview with: Anita Kozyrskyj PhD Professor in Pediatrics Faculty of Medicine & Dentistry School of Public Health University of Alberta MedicalResearch.com: What is the background for this study? Response: Data for this study were collected in the Canadian Healthy Infant Longitudinal Development (CHILD) cohort of over 3,500 full-term infants born between 2009 and 2012. When infants were 3-4 months of age, parents provided a sample of their poop. At that time, parents checked-off responses to questions about their home, including type and frequency of cleaning product use. The infant poop was initially frozen, then thawed later to extract DNA from the sample and identify microbes on the basis of their DNA sequence.  (more…)
Author Interviews, OBGYNE, Pediatrics / 20.09.2018

MedicalResearch.com Interview with: Vida Maralani PhD Associate Professor Department of Sociology Cornell University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Breastfeeding is a time-intensive and culturally and emotionally charged topic in the U.S. with many different stakeholders. Women hear the strong message that they should breastfeed their infants for the first year of life, yet it is unambiguously clear that they find these guidelines hard to follow in practice. We were interested in exploring how breastfeeding duration is associated with how many children women go on to have. Our results show that women who breastfeed their first child for five months or longer are more likely to have three or more children, and less likely to have only one child, than women who breastfeed for shorter durations or not at all. Women who initiate breastfeeding did not differ in how many children they expected to have before they started their families. Rather, the number of children women actually bear differs by how long they breastfeed their first child. Women who breastfeed for shorter durations are more likely to have fewer children than they expected than to have more children than expected. In contrast, women who breastfeed longer are as likely to achieve their expectations as to exceed them, and they are nearly as likely to have more children than they expected as they are to have fewer.

MedicalResearch.com Interview with: Dr Ruth Blackburn PhD  UKRI Innovation Fellow UCL Institute of Health Informatics Dr Ruth Blackburn PhD  UKRI Innovation Fellow UCL Institute of Health Informatics  MedicalResearch.com: What is the background for this study? What are the main findings? Response: In England one child in every classroom is admitted to hospital with an adversity related injury (i.e. violence, intentional self-injury, or drug or alcohol misuse) between the ages of 10 and 19 years. These young people are more likely than their classmates to be re-admitted to hospital or to die within 10 years. We investigated how the rate of hospital admissions with an adversity related injury has changed over time among young people aged 10-24 years, using administrative data for National Health Service hospitals in England. We found that between 2012 and 2016, rates of admission with an adversity related injury (including intentional self-injury) increased steeply for girls, with the biggest increase (6% per year) among 15-19 year olds. During the same time period, rates of admission with an adversity related injury decreased in boys aged 15-24 years (4-5% per year) but increased slightly for 10-14 year olds (3% per year).  (more…)

MedicalResearch.com Interview with: Melissa T. Merrick, PhD Behavioral Scientist, Surveillance Branch, Division of Violence Prevention CDC MedicalResearch.com: What is the background for this study? Response: Childhood experiences build the foundation for health throughout a person’s life. Adverse childhood experiences (ACEs) are potentially traumatic experiences, which occur in childhood. Exposure to ACEs, especially for young people without access to safe, stable, nurturing relationships and environments, can impact health in many ways, including increased risk of chronic disease, engagement in risky behaviors, limited life opportunities, and premature death.

Author Interviews, Endocrinology, Environmental Risks, JAMA, Pediatrics, Thyroid Disease / 17.09.2018

MedicalResearch.com Interview with: Carrie Breton ScD Associate Professor and Director of the MADRES Center Division of Environmental Health Los Angeles, CA 90032 MedicalResearch.com: What is the background for this study? What are the main findings? Response: I am interested in how the environment can influence our very early development, starting in the womb. I have studied the health effects of air pollutants on children for several years and wanted to focus now on the earliest windows of susceptibility.  Thyroid hormones play a critical role in fetal growth and development. We knew we could get information on newborn thyroid levels from the California Department of Public Health’s newborn screening program therefore look at this question in our study population. We found that exposure to high levels of PM2.5 and PM10 throughout most of pregnancy affected TT4 levels in newborns. (more…)
Author Interviews, Cannabis, CDC, JAMA, Pediatrics / 17.09.2018

MedicalResearch.com Interview with: Katrina Trivers, PhD, MSP Lead author and lead epidemiologist Office on Smoking and Health CDC MedicalResearch.com: What is the background for this study? Response: Although we’ve seen considerable declines in the use of regular cigarettes among U.S. youth over the past several decades, the tobacco product landscape is evolving, and the use of other tobacco products have become increasingly popular. For example, as of 2014, e-cigarettes have become the most commonly used tobacco product among US youth. During 2011-2015, e-cigarette use increased 900% among U.S. high school students before declining in 2016. No change was observed in 2017, with about 2 million youth, including 12% of high school students and 3% of middle school students, reporting they had used e-cigarettes in the past 30 days. This is a public health concern because the use of any form of tobacco product is unsafe among youth, irrespective of whether it’s smoked, smokeless, or electronic. The U.S. Surgeon General has concluded that the aerosol emitted from e-cigarettes is not harmless. It can contain harmful ingredients, including nicotine, carbonyl compounds, and volatile organic compounds known to have adverse health effects. The nicotine in these products is of particular concern given that nicotine exposure during adolescence can cause addiction and can harm the developing adolescent brain. In recent years, many youth have also been using other psychoactive substances in e-cigarettes, including cannabinoids and other illicit drugs. This could have been fueled, in part, by shifts in the social acceptability and access to cannabis as several states have or are considering legalized cannabis sales for adults. A previous CDC study found that in 2015, almost 1 in 3 students reported using e-cigarettes with non-nicotine substances. However, it wasn’t possible to identify what exactly those substances were based on the question. Given the high concurrent use of tobacco and other substances, including cannabis, a more detailed question was added to a future survey to assess the use of cannabis in e-cigarettes among U.S. youth. This study presents the findings from that question. (more…)
Author Interviews, Critical Care - Intensive Care - ICUs, JAMA, Nutrition, Pediatrics / 17.09.2018

MedicalResearch.com Interview with: Sascha Verbruggen, MD, PhD Pediatric intensivist Erasmus MC-Sophia Children's Hospital MedicalResearch.com: What is the background for this study? Response: In critically ill children treated in the pediatric intensive care unit (PICU) are often difficult to feed. The subsequent macronutrient deficit was found to be associated with impaired outcomes in the PICU. Furthermore, being undernourished in the PICU has also been associated with poor outcome of critical illness in children. These associations formed the basis for guidelines recommending initiation of parenteral nutritional support early when enteral feeding is insufficient. However, the multicenter randomised controlled trial (RCT) 'Pediatric Early versus Late Parenteral Nutrition in Critical Illness' (PEPaNIC), including 1440 critically ill children, showed that withholding PN for one week (Late-PN) resulted in fewer new infections and reduced the duration of PICU stay as compared to initiating PN at day 1 (Early-PN). However, withholding PN for one week in critically ill children, who are already undernourished upon admission to the PICU, raised concerns among experts. Therefore we set out to investigate the impact of withholding supplemental PN in a subgroup of critically ill children who were acutely undernourished upon admission to the PICU.  (more…)

MedicalResearch.com Interview with: Scott E. Hadland, MD, MPH, MS Assistant Professor of Pediatrics Boston Medical Center / Boston University School of Medicine MedicalResearch.com: What is the background for this study? Response: Amidst a worsening overdose epidemic in the United States, adolescents and young adults have not been spared. Although evidence-based medications like buprenorphine, naltrexone, and methadone are recommended for adolescents and young adults, the extent to which youth receive these medications — and whether these medications help retain youth in addiction treatment — isn’t yet known.
