Author Interviews, JAMA, Pediatrics, Pharmacology / 16.08.2016

MedicalResearch.com Interview with: Dr Evie Stergiakouli Lecturer in Genetic Epidemiology and Statistical Genetics MRC Integrative Epidemiology Unit University of Bristol Bristol UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: Acetaminophen is considered safe to use during pregnancy. However, research suggests that acetaminophen use in pregnancy is associated with abnormal neurodevelopment. It is possible that this association might be confounded by unmeasured behavioural factors linked to acetaminophen use. We compared acetaminophen use during pregnancy to postnatal acetaminophen use and partner's acetaminophen use. Only acetaminophen use during pregnancy has the potential to cause behavioural problems in the offspring. Any associations with postnatal acetaminophen use and partner's acetaminophen use would be due to confounding. Behavioural problems in the offspring were only associated with acetaminophen use during pregnancy. (more…)
Author Interviews, Pain Research, Pediatrics / 15.08.2016

MedicalResearch.com Interview with: Amy Baxter MD CEO MMJ Labs LLC MedicalResearch.com: Would you tell us a little about your background? How did you develop an interest in pain management and prevention? Response: As a pediatric emergency doctor, I found it interesting that doctors could prevent pain but sometimes couldn't be bothered to do so. The lack of empathy and impatience is built into emergency training - we learn to diagnose and fix things quickly, not comfort and support. I decided to research how pain management would make procedures more successful, or faster, to convince doctors to use pain management for THEIR benefit. MedicalResearch.com: What is the background for the Buzzy(r) device? How does it impact pain sensation? Response: When my 4 year old had a horrible vaccination experience, I realized that a fast effective parent-controlled option for pain relief was needed. I knew that cold running water could eliminate the pain from a burned finger using physiology called gate control. Basically, the small pain nerves run alongside big motion nerves, so if you heavily stimulate motion you scramble the pain sensation. Rubbing a bumped elbow is another good example. Vibration alone didn't work enough for needles, but when I added ice the two sensations of cold and motion eliminated pain in 84% of seniors getting a flu shot. We got a grant from the NIH to develop and study Buzzy - it's a palm sized vibration unit with a place on the back to attach ice "wings", that freeze solid. You put them both where an injection will go for a minute or less, then move them "between the brain and the pain" while doing a needle procedure. There are about 14 studies on IV access or blood draws and 6 on injections, showing between 50 and 88% pain reduction. Several studies have demonstrated that Buzzy is truly a physiologic intervention, not a distraction: it didn't work for injections when only used for 10 seconds, too little time to block the pain nerves. But it worked really well for blood draws in severely cognitively impaired children for whom distraction wasn't an option. (more…)
Author Interviews, Infections, Pediatrics / 12.08.2016

MedicalResearch.com Interview with: Marieke de Hoog Assistant Professor Julius Centrum voor Gezondheidswetenschappen en Eerstelijnsgeneeskunde UMC Utrecht The Netherlands  MedicalResearch.com: What is the background for this study? Response: Acute otitis media (AOM) is a prime reason for doctor consultations and antibiotic use in children. Although symptoms of AOM may resolve spontaneously, these infections have a significant impact on child and family life and carry a considerable health care and economic burden.  Acute otitis media occurring early in life, also called early-onset AOM, has been suggested as a risk factor for subsequent  Acute otitis media episodes during childhood and could therefore also impact health care resource use. Identifying the critical age-period and quantifying the long-term consequences of early-onset AOM is important to guide future management and prevention programs aiming to reduce the burden of AOM.

Author Interviews, JAMA, Lipids, Pediatrics / 10.08.2016

MedicalResearch.com Interview with: Paula Lozano, MD MPH Associate Medical Director, Research and Translation Group Health Physicians Senior Investigator Group Health Research Institute Metropolitan Park East Seattle, WA 98101 MedicalResearch.com: What is the background for this study? Response: This wasn’t a study, but rather a study of studies, to support the US Preventive Services Task Force in updating its previous recommendation of I: insufficient to assess the balance of benefits and harms. We conducted two systematic evidence reviews of screening children and adolescents: 1. for familial hypercholesterolemia (FH, a genetic disorder that interferes with the body’s ability to metabolize cholesterol and can result in early coronary heart disease); and 2. for multifactorial dyslipidemia—which we defined as elevated LDL cholesterol or total cholesterol, not caused by familial hypercholesterolemia. LDL and total cholesterol were of interest because they are considered atherogenic. One of the challenges of lipid screening in youth is that blood levels of these atherogenic lipids are known to fluctuate during the course of childhood and adolescence. It’s sort of a W-shaped curve, with a peak at age 9-11 years. So for a given child, the definition of what’s an elevated LDL or total cholesterol level will change with age. Also, two-thirds of kids identified as having high cholesterol through universal screening would not go on to have high cholesterol as adults. (more…)
Accidents & Violence, Author Interviews, Ophthalmology, Pediatrics / 09.08.2016

MedicalResearch.com Interview with: R. Sterling Haring, DO, MPH Center for Healthcare Quality and Patient Safety University of Lugano, Switzerland 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: Chemical burns of the eye are among the most serious and emergent of eye injuries. In the worst cases, corrosive chemicals can eat into the eye and damage internal structures, rendering the individual with little or no vision in the affected eye. Given the proximity of the eyes to one another, it is not uncommon for these injuries to be bilateral, further complicating the clinical picture. Working-age individuals, particularly men, are known to be a high-risk group for these types of injuries. In the first nationwide study on this issue, we found that 1-year old infants were at substantially higher (1.5x) risk of these injuries than the highest-risk age group among adults; 2-year-olds were a close second. These injuries tapered off as children grew older, such that the risk among 1-year-old infants was 13 times higher than that of 7-year-old children. Across all ages, injuries occurred most frequently among lower-income households. (more…)
Author Interviews, Education, Pediatrics / 06.08.2016

MedicalResearch.com Interview with: David C. Geary, Ph.D. Curators’ Distinguished Professor Thomas Jefferson Fellow Department of Psychological Sciences Interdisciplinary Neuroscience Program University of Missouri Columbia, MO MedicalResearch.com: What is the background for this study? What are the main findings? Response: In an earlier study, we found that children’s understanding of numbers and the relations among them (e.g., that 6 = 5 + 1 & 4 + 2 & 3 + 3…) at the beginning of 1st grade predicted their performance on math measures in adolescence, controlling IQ, working memory, family background and other factors. These are measures that predict employability and wages in young adults and thus is practically important. We were interested in understanding the very early quantitative knowledge that predicts children’s later number knowledge. We tested children on a variety of quantitative measures 2 years before they entered kindergarten and in kindergarten gave them the same type of number test that we used in the first study. We found that 3 year olds' cardinal knowledge was critical to their later understanding of number relations, controlling IQ and many other factors. Cardinal knowledge is their understanding of the quantities associated with number words. So, if you ask a child to give you 3 toys, and they give you a handful, they do not understand what ‘three’ means. Young children with poor knowledge of number words, we at risk for poor math outcomes in kindergarten, controlling other factors. (more…)
Author Interviews, Nutrition, Pediatrics / 04.08.2016

MedicalResearch.com Interview with: Lauren McGale Research Assistant & PhD Student University of Liverpool MedicalResearch.com: What is the background for this study? What are the main findings? Response: Food marketing has been highlighted as a key factor which contributes to childhood obesity, and food–packaging as a marketing tool is currently under-researched. Placing licensed-characters, which are those borrowed from movies and TV shows, have previously been shown to affect children’s food choices and taste preferences in favour of the product they appear on, and their use in TV advertising is regulated here in the UK. However, this is the first study to examine the influence of brand equity characters in this context, which are characters created solely to represent a particular product/brand (for example, Tony the Tiger for Kellogg’s Frosties), and these characters are currently exempt from UK TV advertising regulations. As these brand equity characters typically promote foods which are high in fat, salt and sugar, it is crucial that we understand their impact on children’s food choices and preferences. Our findings were consistent with the existing literature on various types of promotional characters, demonstrating that children displayed a preference for the taste of foods presented with the brand equity character on the packaging, compared to identical foods without the character, and were also more likely to choose these foods as snacks. This was true even when the characters were placed on foods they were not usually associated with. (more…)
Asthma, Author Interviews, NEJM, Pediatrics / 04.08.2016

MedicalResearch.com Interview with: Donata Vercelli, MD Professor of Cellular and Molecular Medicine, University of Arizona Director, Arizona Center for the Biology of Complex Diseases Associate Director, Asthma and Airway Disease Research Center The BIO5 Institute Tucson, AZ 85721 MedicalResearch.com: What is the background for this study? Response: By probing the differences between two farming communities—the Amish of Indiana and the Hutterites of South Dakota—our interdisciplinary team (which included, among others, Erika von Mutius from Ludwig-Maximilians University in Munich, Carole Ober and Anne Sperling from the University of Chicago, and myself) found that substances in the house dust from Amish, but not Hutterite, homes shape the innate immune system in ways that may prevent the development of allergic asthma. Growing up in a microbe-rich farm environment has been known to protect against asthma. Our current study extends these findings by showing that in both humans and mice protection requires engagement of the innate immune system. The Amish and Hutterite farming communities in the United States, founded by immigrants from Central Europe in the 18th and 19th centuries, provide textbook opportunities for comparative studies. The Amish and the Hutterites have similar genetic ancestry and share lifestyles (e.g., family size, diet, lack of exposure to indoor pets) known to affect asthma risk. However, their farming practices differ. The Amish have retained traditional methods, live on single-family dairy farms and rely on horses for fieldwork and transportation. In contrast, the Hutterites live on large communal farms and use modern, industrialized farm machinery. This distances young Hutterite children from the constant daily exposure to farm animals.

Author Interviews, Brain Injury, JAMA, Pediatrics / 02.08.2016

MedicalResearch.com Interview with: Danny G. Thomas, MD, MPH Department of Pediatrics, Emergency Medicine Children’s Hospital of Wisconsin Corporate Center Milwaukee, WI MedicalResearch.com: What is the background for this study? What are the main findings? Response: This was a secondary analysis of a randomized controlled trial of strict rest after concussion published last year. We wanted to find out how mental and physical activity levels related to symptom spikes or sudden increases in concussion symptoms. We found that one in three patients had symptoms spikes in recovery. Patients who had symptom spikes tended to have higher symptoms in the emergency department and throughout recovery. Most symptom spikes were not associated with an increase in physical and mental activity level the day prior. We did find that a sudden increase in activity like returning to school did increase the risk of having a symptom spike, but the good news is these symptom spikes seemed to resolve the following day and did not impact recovery by 10 days.

Author Interviews, Genetic Research, JAMA, Pediatrics, Surgical Research / 26.07.2016

MedicalResearch.com Interview with: Dr. Katherine Nelson MD Staff Paediatrician with the Paediatric Advanced Care Team at SickKids and PhD student University of Toronto MedicalResearch.com: What is the background for this study? Response: Trisomy 13 and 18 are rare genetic conditions that cause problems in multiple organ systems, including heart defects and severe neurologic impairment.  A majority of children with trisomy 13 and 18 die in the first days to weeks after birth, though a small number survive beyond one year.  For years, health care providers have debated the effectiveness and ethics of surgical interventions in these populations.

Author Interviews, Cannabis, JAMA, Pediatrics / 25.07.2016

MedicalResearch.com Interview with: George Sam Wang MD FAAP Assistant Professor of Pediatrics Section of Emergency Medicine, Medical Toxicology Department of Pediatrics University of Colorado Anschutz Medical Campus Children's Hospital Colorado MedicalResearch.com: What is the background for this study? Response: Many states have allowed medical and now recreational marijuana. The impact on pediatric population has not been fully described. MedicalResearch.com: What are the main findings? Response: Unintentional exposures presenting to our children's hospital and calls to our regional poison center significantly increased after our state allowed recreational marijuana. MedicalResearch.com: What should readers take away from your report? Response: Exposures in children are increasing in our state that allows medical and recreational Marijuana, many were edible products. Marijuana products should be treated like medications and household products in home and properly and safely stored. States looking to legalize marijuana need to consider safety rules and regulations during rule making processes. (more…)
Author Interviews, BMJ, Nutrition, Pediatrics / 21.07.2016

MedicalResearch.com Interview with: Sharon Carstairs PhD Student Public Health Research University of Aberdeen, Aberdeen MedicalResearch.com: What is the background for this study? Response: The introduction of solid foods is a key period when the milk diet is no longer able to meet all dietary needs, additionally it is a key time for food learning and development of eating preferences in a child’s life. It is vital that children are provided with nutritionally balanced foods as well as a variety of foods to meet dietary requirements and are exposed to different tastes and textures. Some parents provide home-cooked meals however, there is a large market of commercially available infant/toddler meals which can provide parents with a convenient alternative to home-cooking. (more…)
Author Interviews, Diabetes, JAMA, Pediatrics / 20.07.2016

MedicalResearch.com Interview with: Andy Menke PhD Social & Scientific Systems, Inc. Silver Spring, MD, 20910 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Limited information was available on the prevalence of diabetes among adolescents in the US, particularly the percentage that are undiagnosed and unaware of the condition. We found that 0.8% of adolescents 12-19 years of age had diabetes and 18% had prediabetes. Of those with diabetes, 29% overall were unaware of it and this increased to 40% among Hispanic adolescents and 50% among non-Hispanic black adolescents. (more…)
Author Interviews, Depression, JAMA, Mental Health Research, Pediatrics / 18.07.2016

MedicalResearch.com Interview with: Dr Carmen Pace MPsych (Clin Child) PhD AMACPA Clinical Psychologist and Research Fellow Murdoch Childrens Research Institute The Royal Children’s Hospital Flemington Rd Parkville, Victoria AUS MedicalResearch.com: What is the background for this study? Response: We know that mothers of very preterm infants (born prior to 32 weeks gestation) are at higher risk for psychological distress compared to mothers who have healthy full term infants. However, detailed longitudinal research looking at how symptoms evolve over the first weeks and months is limited, and fathers are largely neglected in the literature. We addressed these gaps by assessing symptoms of depression and anxiety in both mothers and fathers every two weeks for the first twelve weeks after birth, and again at six months. (more…)
Author Interviews, Education, Pediatrics, Technology / 18.07.2016

MedicalResearch.com Interview with: Lauren J. Myers, Ph.D. Assistant Professor Psychology Department Lafayette College Easton, Pennsylvania MedicalResearch.com: What is the background for this study? Response: Many families with young children use video chat to connect with family and friends--but what do children understand about the on-screen people and content of these interactions? The American Academy of Pediatrics discourages screen time for kids under 2 years because children who watch a lot of media often have poor language skills, and they miss out on other activities that would be more developmentally appropriate. However, in this study we wondered whether there is a difference between putting a baby in front of a television and having an interactive exchange via video chat. (more…)
Author Interviews, Flu - Influenza, JAMA, Pediatrics, Vaccine Studies / 07.07.2016

MedicalResearch.com Interview with: Marta C. Nunes, PhD DST/NRF:Vaccine Preventable Diseases Respiratory and Meningeal Pathogens Research Unit University of Witwatersrand Chris Hani Baragwanath Academic Hospital Soweto, South Africa MedicalResearch.com: What is the background for this study? Response: Young infants are at increased risk for influenza infection and hospitalizations associated with influenza infection. While active annual influenza vaccination is the most efficient mode for the prevention of influenza infection, current vaccines are poorly immunogenic and not licensed for use in infants (more…)
Author Interviews, JAMA, Pediatrics / 04.07.2016

MedicalResearch.com Interview with: Dr. Kirsten Herrick Ph.D. Division of Health and Nutrition Examination Surveys National Center for Health Statistics Centers for Disease Control and Prevention Hyattsville, Maryland MedicalResearch.com: What is the background for this study? What are the main findings? Response: The benefits of breastfeeding are well established: for children, it offers protection against infections and increases in intelligence; for nursing women, it protects against breast cancer and improves birth spacing. But there is no nationally representative information about whether there are differences in breastfeeding by birth weight (BW). Using data from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2014, we estimated the proportion of infants ever breastfed (initiated), and those reporting any breastfeeding at 1 month, 4 months, and 6 months by birth weight categories and birth year cohorts. Our sample size was 13,859. (more…)
Accidents & Violence, Author Interviews, Pediatrics, Toxin Research / 28.06.2016

MedicalResearch.com Interview with: Thomas Swain, MPH Research Assistant, The Center for Injury Sciences, Division of Trauma, Burns and Surgical Critical Care, Department of Surgery University of Alabama at Birmingham Birmingham, AL 35294 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Case reports show that the number of laundry pod detergent related cases is increasing rapidly and children are disproportionately affected by pod detergent. Pod detergent is highly concentrated and contained in a water-soluble membrane. Prior research of pod laundry detergent did not include regular, non-pod detergent; this exclusion rendered cases and severity of cases between the two incomparable. This study, comparing regular laundry detergent and pod detergent, from 2012-2014 in the United States, using national data from emergency department visits, found that children under 5 accounted for 93.8% of pod detergent related exposures and 71.8% of non-pod exposures. Importantly, 71.8% of pod exposures were diagnosed as poisoning while 72.2% of non-pod exposures were diagnosed as contact dermatitis. Those exposed to pods were 4.02 times as likely to be hospitalized, a marker for severe injury, when compared to non-pod detergent (OR: 4.02; 95% CI: 1.96-8.24). (more…)

MedicalResearch.com Interview with: Lu Qi, MD, PhD, FAHA HCA Regents Distinguished Chair and Professor Director, Tulane University Obesity Research Center Department of Epidemiology Tulane University School of Public Health and Tropical Medicine New Orleans, LA 70112 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prenatal malnutrition and other stresses may cause small newborn babies, who are more likely develop type 2 diabetes and other chronic diseases during adulthood. However, whether such relation is causal remains to be determined. Genetic associations provide a new approach to provide evidence for such causality. (more…)
Author Interviews, Mental Health Research, Pediatrics, Telemedicine / 23.06.2016

MedicalResearch.com Interview with: Mirna Becevic, PhD, MHA Assistant Research Professor University of Missouri - Department of Dermatology Missouri Telehealth Network MedicalResearch.com: What is the background for this study? Response: Psychiatry is, by far, the biggest utilizer of telemedicine services on the Missouri Telehealth Network (MTN). MTN supports an average of 4000 tele-psychiatry appointments every month, and 10% of those are provided by the University of Missouri Department of Psychiatry. Since we are all aware of the ever-increasing demand for child and adolescent psychiatry, but also the stigma that goes along with it, we wanted to examine more closely the actual usage of those services at the University of Missouri.

Anesthesiology, Author Interviews, Cognitive Issues, NYU, Pediatrics, Science / 23.06.2016

MedicalResearch.com Interview with: Guang Yang, Ph.D. Assistant Professor NYU Langone School of Medicine Alexandria Center for Life Sciences New York, NY 10016 MedicalResearch.com: What is the background for this study? How common is the problem of long-lasting behavioral deficits after repeated anesthesia exposure in neonates? Response: Each year, in the United States alone, more than 1 million children under 4 years of age undergo surgical procedures that require anesthesia. Many lines of evidence from animal studies have shown that prolonged or repeated exposure to general anesthesia during critical stages of brain development leads to long-lasting behavioral deficits later in life. The results from human studies are less clear, although some studies suggest a higher incidence of learning disabilities and attention-deficit and hyperactivity disorders in children repeatedly exposed to procedures requiring general anesthesia. To date, there has been no effective treatment to mitigate the potential neurotoxic effects of general anesthesia. (more…)
Author Interviews, Heart Disease, Pediatrics, Weight Research / 22.06.2016

MedicalResearch.com Interview with: Annika Rosengren MD Department of Molecular and Clinical Medicine, Institute of Medicine Sahlgrenska Academy University of Gothenburg, Gothenburg, Sweden MedicalResearch.com: What is the background for this study? What are the main findings? Response: In an earlier study we found that while hospitalizations for heart failure decreased among people aged 55 and older in Sweden 1987-2006, there was a clear increase among those younger than 45 years, particularly in young men. We thought that increasing body weight in the population might be a factor behind this. We used anonymized data from more than 1.6 million Swedish men from the Swedish conscript registry aged on average 18 and followed them from adolescence onwards. Those who were overweight as teenagers were markedly more likely to develop heart failure in early middle age. The increased risk of heart failure was found already in men who were within the normal body weight range (a body mass index of 18.5 to 25) in adolescence, with an increased risk starting in those with a BMI of 20 and rising steeply to a nearly ten-fold increased risk in those who were very obese, with a BMI of 35 or over. Among men with a BMI of 20 and over, the risk of heart failure increased by 16% with every BMI unit, after adjustments for factors that could affect the findings, such as age, year of enlistment into the Swedish armed forces, other diseases, parental education, blood pressure, IQ, muscle strength and fitness.

Author Interviews, Cannabis, OBGYNE, Pediatrics / 21.06.2016

MedicalResearch.com Interview with: Dr. Hanan El Marroun, PhD Assistant Professor Department of Child and Adolescent Psychiatry, Department of Epidemiology The Generation R Study Erasmus, The Netherlands MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background for the study is that little is known about the potential long-term effects of cannabis exposure during pregnancy on child development. The main findings are the prenatal cannabis exposure was associated with differences in cortical thickness in childhood. MedicalResearch.com: What should readers take away from your report? Response: That our findings suggest an association between prenatal cannabis exposure and cortical thickness in children. However, the results must be carefully interpreted, as there may be other factors involved that we did not take into account. Therefore, further research is needed to explore the causal nature of this association. (more…)
Author Interviews, Mental Health Research, Pediatrics, Psychological Science, Radiology / 19.06.2016

MedicalResearch.com Interview with: Dr. Luca Passamonti MD Department of Clinical Neurosciences University of Cambridge MedicalResearch.com: What is the background for this study? Dr. Passamonti: We wanted to study if the brain of young people with two different forms of conduct disorder (CD) (https://en.wikipedia.org/wiki/Conduct_disorder), a neuropsychiatric disease associated with severe and persistent antisocial behaviors (weapon use, aggression, fire-setting, stealing, fraudulent behavior), was different from that of young peers with no such abnormal behaviors. There is already evidence that conduct disorder may have a biological basis (i.e., reduced levels of cortisol under stress) and brain alterations but a whole “map” of the brain in conduct disorder studying cortical thickness was never been done before. (more…)
Author Interviews, Depression, JAMA, OBGYNE, Pediatrics / 17.06.2016

MedicalResearch.com Interview with: Mari Videman Senior Consultant in Child Neurology BABA Center Children’s Hospital, Helsinki University Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Depression and anxiety are common during pregnancy, and up to 5% of all pregnant women are treated with serotonin uptake inhibitors (SRI). It is now known that SRIs do not cause major malformations in humans, however recent animal studies have suggested that fetal early SRI exposure may cause changes in brain microstructure and neuronal signaling. Prior human studies have shown that fetal SRI exposure leads to transient postnatal adaptation syndrome, as well as to an increased risk of developing childhood depression. We used electroencephalography (EEG) and advanced computational methods to assess both the local and global cortical function of the newborn brain. We found that several aspects of newborn brain activity are affected by exposuse to SRI during pregnancy. Most importantly, the communication between brain hemispheres, and the synchronization between cortical rhythms were weaker in the SRI-exposed newborns. These changes were most likely related to SRI exposure, because they did not correlate with the psychiatric symptoms of the mothers. (more…)
Author Interviews, OBGYNE, Pediatrics, Social Issues / 17.06.2016

MedicalResearch.com Interview with: Kelli A. Komro, MPH, PhD, Professor Director of Graduate Studies Behavioral Sciences and Health Education Jointly Appointed, Epidemiology Rollins School of Public Health Emory University Atlanta, GA 30322 MedicalResearch.com: What is the background for this study?  Dr. Komro: Epidemiologists have done a thorough job describing the income-health gradient, which shows a clear association between income and health. That is, as income increases, exposure to health risks and premature mortality decreases. Each step down on the income ladder decreases one’s health for many reasons related to material resources, physical environment exposures and social circumstances. The income to health association begins at birth, and more than one in four women giving birth in the U.S. are below the poverty level, putting nearly 1 million babies at risk each year. Low-income mothers are more likely to give birth prematurely, to have low birth weight babies, and to suffer the death of their infant during the post-neonatal period (28 to 364 days old). Given the importance of the income-health gradient, we set out to test the health effects of policies that are designed to increase economic security among low-income families. Our main question is: Do policies designed to reduce poverty and improve family economic security also improve health? One relevant policy is minimum wage laws. A federal minimum wage was first enacted in 1938. The real value (in 2015 dollars) of the federal minimum wage reached a high of $10.85 in 1968. The current federal rate is $7.25. Many cities and states have passed minimum wage laws that are higher than the federal rate, and currently there is a range of minimum wage increases under active public and policymaker discussion. Given that some states pass minimum wage standards and others do not, and that laws within states change over time, we took advantage of all the changes that have occurred to design a natural experiment. Our natural experiment examined the effects of state minimum wage laws on infant health. (more…)

MedicalResearch.com Interview with: Leland McClure, PhD Director in Medical Affairs for Quest Diagnostics Fellow of the American Board of Forensic Toxicology MedicalResearch.com: What is the background for this study? Dr. McClure: Quest Diagnostics is the leading provider of diagnostic information services, providing clinical lab testing to about one in three American adults each year. As a result, we've amassed the largest private clinical laboratory database in the United States, based on 20 billion data points from lab testing. Quest uses this data (in de-identified, HIPAA compliant form) to perform research -- called Quest Diagnostics Health Trends(TM) -- to reveal insights on important health issues to inform clinical patient management and health policy. Other Health Trends reports have focused on diabetes, pregnancy and influenza, among others. (more…)
Author Interviews, JAMA, Microbiome, Pediatrics, Weight Research / 13.06.2016

MedicalResearch.com Interview with: Dr. Katri Korpela, PhD University of Helsinki Helsinki MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Korpela: Previous studies have shown that breastfeeding reduces the frequency of infections in the child and is associated with lower risk of childhood overweight. Conversely, antibiotic use in early life is associated with increased BMI. Both antibiotic use and breastfeeding are known to influence the infant's microbiota. However, these two factors have not been studied together and it was not known whether antibiotic use could modify the beneficial effects of breastfeeding. We collected data on lifetime antibiotic use, breastfeeding duration, and BMI in a group of daycare-attending children aged 2-6 years. We found that the beneficial effects on long breastfeeding, particularly as regards BMI development, were evident only in the children who did not get antibiotics in early life. Antibiotic use before or soon after weaning seemed to eliminate the protection against elevated BMI in preschool age and weaken the protection against infections after weaning. (more…)
