Author Interviews, Cannabis, JAMA, Pediatrics, UC Davis / 02.01.2017

MedicalResearch.com Interview with: Magdalena Cerda, DrPH, MPH Vice Chancellor's Chair in Violence Prevention Associate Director, Violence Prevention Research Program UC Davis Violence Prevention Research Program MedicalResearch.com: What is the background for this study? What are the main findings? Response: The potential effect of legalizing marijuana for recreational use has been a topic of considerable debate since Washington and Colorado first legalized its use for adults in 2012. Alaska, Oregon and Washington, D.C., followed suit in 2014, and voters in California, Massachusetts and Nevada approved recreational use this past November. In our study, we examined changes in perceived risk of marijuana use, and in use of marijuana among school-attending adolescents, in Washington and Colorado, following legalization of recreational marijuana use, and compared pre- to post-legalization changes in these two states to changes in the 45 contiguous US states that had not legalized recreational marijuana use. Marijuana use significantly increased and its perceived harm decreased among eighth- and 10th-graders in Washington state following enactment of recreational marijuana laws. There was no change in use or perceived harm among 12th graders or among similar grades in Colorado. In particular, the data showed that legalization of recreational marijuana use significantly reduced perceptions of marijuana’s harmfulness by 14 percent and 16 percent among eighth and 10th graders and increased their past-month marijuana use by 2 percent and 4 percent in Washington state but not in Colorado. Among states without legalized marijuana use, the perceived harmfulness also decreased by 5 percent and 7 percent for students in the two grades, but marijuana use decreased by 1.3 percent and .9 percent. Among older adolescents in Washington state and all adolescents surveyed in Colorado, there were no changes in perceived harmfulness or marijuana use in the month after legalization. (more…)
Author Interviews, Kaiser Permanente, Lancet, Pediatrics, Weight Research / 29.12.2016

MedicalResearch.com Interview with: De-Kun Li, MD, PhD Senior Research Scientist Division of Research Kaiser Foundation Research Institute Kaiser Permanente Oakland, CA 94612 MedicalResearch.com: What is the background for this study? Response: The composition of gut microbia (microbiome) has emerged as a key contributor to human disease risk. The external influence on the composition of microbiome in early childhood, especially in infancy, has been linked to increased risk of childhood obesity. Several studies have examined use of antibiotics in infancy and reported an association between use of antibiotics and increased risk of childhood obesity. This has caused a great uncertainty among both pediatricians and parents regarding treatment of infant infections. However, the previous studies failed to separate the effect of underlying infections for which antibiotics were used from the effect of the antibiotics itself. The contribution of our study was to examine the effects of infections and antibiotic use separately. (more…)
Author Interviews, Genetic Research, Lancet, Pediatrics, Schizophrenia / 22.12.2016

MedicalResearch.com Interview with: Dr Lucy Riglin Division of Psychological Medicine and Clinical Neurosciences MRC Centre for Neuropsychiatric Genetics and Genomics Cardiff University School of Medicine Cardiff UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: Schizophrenia is a mental disorder that usually occurs after puberty. However, previous research suggests that individuals who go on to develop schizophrenia often presented cognitive, social, behavioural, and emotional impairments in childhood. Our study found that, in a general population sample, genetic risk for schizophrenia was associated with these childhood impairments as early as age 4 years. (more…)
Author Interviews, Brain Injury, JAMA, Pediatrics / 21.12.2016

MedicalResearch.com Interview with: Roger Zemek, MD, FRCPC Associate Professor, Dept of Pediatrics and Emergency Medicine, Clinical Research Chair in Pediatric Concussion, University of Ottawa Director, Clinical Research Unit, Children’s Hospital of Eastern Ontario Ottawa, ON MedicalResearch.com: What is the background for this study? Response: While current concussion protocols endorse the conservative view that children should avoid physical activity until completely symptom-free, there is little evidence beyond expert opinion regarding the ideal timing of physical activity re-introduction. In fact, while rest does play a role in concussion recovery, protracted physical rest may actually negatively impact concussion recovery. Further, physiological, psychological, and functional benefits of early physical rehabilitation are observed in other disease processes such as stroke (which is an example of a severe traumatic brain injury). Therefore, our objective was to investigate the relationship between early physical activity (defined within 7 days of the concussion) and the eventual development of persistent post-concussion symptoms at one month.

Author Interviews, JAMA, Pediatrics / 21.12.2016

MedicalResearch.com Interview with: Eyal Cohen, MD, MSc, FRCP(C) Staff Physician, Paediatrics The Hospital for Sick Children Associate Scientist, Research Institute Child Health Evaluative Sciences Associate Professor, University of Toronto   MedicalResearch.com: What is the background for this study? What are the main findings? Response: Major structural or genetic congenital anomalies affect approximately 2 percent to 5 percent of all births in the United States and Europe. Mothers of children born with major congenital anomalies face serious challenges such as high financial pressures, as well as the burden of providing care to a child with complex needs within the home setting, which can impair a mother's health. Little is known about the long-term health consequences for the mother. We assessed whether the birth of an infant with a major congenital anomaly was subsequently associated with an increased risk of death of the infant's mother. The population-based study (n = 455,250 women) used individual-level linked Danish registry data for mothers who gave birth to an infant with a major congenital anomaly between 1979 and 2010, with follow-up until December 31, 2014. A comparison group was constructed by randomly sampling, for each mother with an affected infant, up to 10 mothers matched on maternal age, parity (the number of children a woman has given birth to), and year of infant's birth. Mothers in both groups were an average age of 29 years at delivery. After a median follow-up of 21 years, there were 1,275 deaths (1.60 per 1,000 person-years) among 41,508 mothers of a child with a major congenital anomaly vs 10,112 deaths (1.27 per 1,000 person-years) among 413,742 mothers in the comparison group. Mothers with affected infants were more likely to die of cardiovascular disease, respiratory disease, and other natural causes. (more…)

MedicalResearch.com Interview with: Dr Jamie G Cooper Consultant in Emergency Medicine Aberdeen Royal Infirmary Aberdeen UK MedicalResearch.com: What is the background for this study? Response: Choking in children can be fatal and regularly grapes can be the cause.  We believe that public awareness of the choking hazard posed by grapes (and other similarly shaped foods, such as cherry tomatoes) is not wide spread.  By publishing this article we aimed to highlight the problem to health professionals who look after children and also to the public at large in an attempt to reduce the number of future episodes.

Author Interviews, Pediatrics, Pulmonary Disease / 17.12.2016

MedicalResearch.com Interview with: Elizabeth Foglia, MD MSCE Assistant Professor of Pediatrics University of Pennsylvania Perelman School of Medicine Attending Neonatologist Hospital of the University of Pennsylvania The Children's Hospital of Philadelphia MedicalResearch.com: What is the background for this study? What are the main findings? Response: Pulse oximetry is a non-invasive method of monitoring oxygen saturation that is frequently used to monitor ill newborns and infants. Previous studies of adults with hypoxemia (low blood oxygen levels) demonstrated that pulse oximetry is less accurate in adults with dark skin, compared to adults with light skin. We sought to determine if skin pigment affects the accuracy of pulse oximetry in infants with hypoxemia. We studied 2 widely used pulse oximeters, and we did not find evidence that skin pigment affects the accuracy of pulse oximetry in infants with hypoxemia. However, the overall performance (combined accuracy and precision) of both oximeters was poor. In addition, one oximeter (the Nellcor Oximax) consistently overestimated the measured blood oxygen level. (more…)
Author Interviews, MRI, OBGYNE, Pediatrics / 17.12.2016

MedicalResearch.com Interview with: Prof Paul D Griffiths, FRCR and Cara Mooney, Study Manager: MERIDIAN Clinical Trials Research Unit The University of Sheffield  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Around three in every 1000 pregnancies is complicated by a fetal abnormality. In the UK Ultrasonography (USS) has, for many years, been the mainstay of antenatal screening and detailed anomaly scanning to detect such abnormalities.  However previous studies have suggested that in utero Magnetic Resonance (iuMR) imaging may be a useful adjunct to USS for detecting these brain abnormalities in the developing fetus. This study was designed to test the diagnostic accuracy and clinical impact of introducing fetal MR in to the diagnostic pathway. Our results show that iuMR has an overall diagnostic accuracy of 93% compared to ultrasound at 68%, this is an increase in diagnostic accuracy of 25%. When divided into gestational age group the improvement in diagnostic accuracy ranged from 23% in the 18-23 week group, and 29% in the 24 week and over group. IuMR provided additional diagnostic information in 49% of cases, changed prognostic information in at least 20% and the contribution to clinical management was felt to be at least ‘significant’ in 35% of cases. IuMR also had high patient acceptability with at least 95% of women stating that they would have an iuMR if a future pregnancy were complicated by a fetal brain abnormality. (more…)
Abuse and Neglect, Author Interviews, Pediatrics, University of Pennsylvania / 16.12.2016

MedicalResearch.com Interview with: Joanne N. Wood, MD, MSHP Assistant Professor of Pediatrics Perelman School of Medicine at the University of Pennsylvania Research Director, SafePlace Faculty, PolicyLab The Children’s Hospital of Philadelphia  MedicalResearch.com: What is the background for this study? Response: Each year the U.S. Army Family Advocacy program (FAP) investigates between 6000 to 9000 reports of alleged abuse or neglect involving children of Army service members.   In approximately 48% of reported cases FAP determines a child was a victim of maltreatment, substantiates the report, and collaborates with local civilian child protection service (CPS) agencies in providing services and ensuring safety. Thus, FAP plays a key role in supporting Army families and protecting children.  But FAP can only investigate and respond to cases of child abuse and neglect about which they are aware. (more…)

MedicalResearch.com Interview with: Kristin N. Ferguson, BSc The Royal Women’s Hospital and Deakin University Melbourne, Victoria, Australia MedicalResearch.com: What is the background for this study? Response: Weaning preterm infants from mechanical ventilation, thereby minimising the risks of having an endotracheal tube in situ which may further damage their fragile lungs, is something all neonatal clinicians are keen to do. We provide clinicians with a straightforward list of safe and effective strategies to help them in this task, as well as pointing out some treatments to either avoid or use with caution. (more…)
Author Interviews, Pain Research, Pediatrics, Vaccine Studies / 13.12.2016

MedicalResearch.com Interview with:

Dr. Anna Taddio PhD Professor in the Leslie Dan Faculty of Pharmacy University of Toronto Adjunct senior scientist and clinical pharmacist at SickKids MedicalResearch.com: What is the background for this study? Response: We do not know enough about how well different pain interventions work over time and when combined together. In this study, we compared the effectiveness of interventions when layered together, starting from simplest to most complicated in terms of implementation, in the first year of life in infants undergoing routine vaccinations. We compared 4 different treatments: 1. placebo (sham), 2. Educational video for parents about how to soothe their infants, 3) video and sucrose (sugar water), 4) video and sucrose and liposomal lidocaine cream. (more…)
Author Interviews, Leukemia, Nature, Pediatrics, UT Southwestern, Weight Research / 13.12.2016

MedicalResearch.com Interview with: Chengcheng (Alec) Zhang, Ph.D. Associate Professor Hortense L. and Morton H. Sanger Professorship in Oncology Michael L. Rosenberg Scholar for Medical Research Department of Physiology UT Southwestern Medical Center MedicalResearch.com: What is the background for this study? Response: New therapeutic targets and approaches are needed to effectively treat leukemia. Acute myeloid leukemia (AML) is the most common form of adult acute leukemia whereas acute lymphoblastic leukemia (ALL) is the most common form of cancer in children; ALL also occurs in adults. Although treatment of pediatric ALL is highly effective, a sizeable number of patients are non-responders who succumb to this disease. The outcome of ALL in adults is significantly worse than for pediatric ALL. Additionally, some types of ALL have a much poorer prognosis than others. Dietary restriction, including fasting, delays aging and has prolonged effects in a wide range of organisms and has been considered for cancer prevention. In certain types of solid tumor,_ENREF_1 dietary restriction regimens are able to promote T cell-mediated tumor cytotoxicity and enhance anticancer immunosurveillance, and coordinate with chemotherapy to promote the anti-cancer effects. However, the responsiveness of hematopoietic malignancies to dietary restriction, including fasting, remains unknown. Furthermore, whether dietary restriction alone can inhibit cancer development is not clear. (more…)
Addiction, Author Interviews, Opiods, Pediatrics / 12.12.2016

MedicalResearch.com Interview with: Nicole Villapiano, MD, MSc Robert Wood Johnson Clinical Scholar Internal Medicine/Pediatrics Institute for Healthcare Policy & Innovation University of Michigan MedicalResearch.com: What is the background for this study? What are the main findings? Response: Over the past few years, research has highlighted that the opioid epidemic is accelerating at a rapid pace across the United States, including in rural areas. What we don’t know is how the opioid crisis is affecting rural moms and their infants. As a doctor that takes care of kids, I was concerned about this. So our team took on this study to explore the differences in rates of maternal opioid use and neonatal abstinence syndrome in rural and urban areas of the US from 2004-2013. Neonatal abstinence syndrome is what happens to babies who are exposed to opioids in their mothers’ womb. When these babies are born and no longer have opioid exposure from mom, they go through a period of opioid withdrawal. These babies can have symptoms that range from difficulty taking a bottle, jitteriness, difficulty sleeping, irritability, and discomfort to more serious problems like prematurity, difficulty breathing, and seizures. Symptoms can last several days to many weeks. Babies with neonatal abstinence syndrome are in the hospital longer than the average newborn, and sometimes require special treatment to help control their symptoms. (more…)
Author Interviews, Hematology, Memory, Pediatrics, Technology / 09.12.2016

MedicalResearch.com Interview with: Steven J. Hardy, Phd Licensed Clinical Psychologist Divisions of Hematology and Oncology Children’s National Health System Assistant Professor of Pediatrics and Psychiatry & Behavioral Sciences George Washington School of Medicine and Health Sciences Washington, DC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Children with sickle cell disease exhibit neurocognitive deficits as a consequence of either silent or overt cerebral infarction or disease-related non-infarct central nervous system effects (likely resulting from chronic anemia and hypoxic events). These complications often lead to impairment in executive functioning (e.g., working memory, attention, inhibition, cognitive flexibility), which can make it difficult to focus in class, plan for long-term school projects, remember and carry out multi-step tasks or assignments, and stay organized. The literature on interventions to reduce neurocognitive sequelae of sickle cell disease is extremely limited. Our research team investigated a promising home-based, computerized cognitive training program (Cogmed) involving repeated practice on performance-adapted exercises targeting working memory with a sample of youth (ages 7 – 16) with sickle cell disease. Of the participants who have enrolled in the study (n = 70), 49% exhibited working memory deficits (<25% in the general population have a working memory deficit) and were randomized to an eight-week waitlist or to begin Cogmed immediately. Participants who used Cogmed demonstrated significant improvements on multiple measures of working memory, while those randomized to the waitlist group only exhibited such improvements after receiving Cogmed. Approximately 25% of participants completed the recommended number of Cogmed sessions (20 – 25 sessions). However, analyses revealed that participants who completed at least 10 sessions (about 50% of the participants) showed comparable levels of working memory improvement. (more…)

MedicalResearch.com Interview with: Eman S. Mahdi, MD, MBChB Pediatric Radiology Fellow Catherine Limperopoulos, PhD Director, Developing Brain Research Laboratory Co-Director of Research, Division of Neonatology Diagnostic Imaging and Radiology Children’s National Health System Washington, DC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Premature birth is a major public health concern in the United States affecting 1 in 10 infants each year. Prematurity-related brain injury is very common and associated with a high prevalence of brain injury and accompanying lifelong neurodevelopmental morbidities. Early disturbances in systemic and cerebral hemodynamics are thought to mediate prematurity-related brain injury. The extent to which cerebral blood flow (CBF) is disturbed in preterm birth is poorly understood, in large part because of the lack of monitoring techniques that can directly and non-invasively measure cerebral blood flow. We report for the first time early disturbances in global and regional cerebral blood flow in preterm infants following brain injury on conventional magnetic resonance imaging (MRI) over the third trimester of ex-uterine life using arterial spin labelling images. In terms of regional differences, we saw a marked decrease in blood flow to the thalamus and the pons, regions known to be metabolically active during this time. (more…)

MedicalResearch.com Interview with: Jonathan Y. Bernard, PhD Inserm UMRS 1153 – Centre for research in Epidemiology and Biostatistics Sorbonne Paris Cité (CRESS) Team ORCHAD: early Origin of the Child Health And Development Hôpital Paul Brousse MedicalResearch.com: What is the background for this study? What are the main findings? Response: Despite the World Health Organization’s recommendations promoting breast feeding, wide variations in breast feeding initiation rates are observed among Western countries: some reach >95%, while others remain <80%. Many individual-level determinants of breast feeding are known, including maternal age, education, ethnicity, smoking and employment status. Less is known regarding cultural determinants, such as religion, which could be underlying and explain rate differences between and within countries. We aimed at comparing countries’ breast feeding rates with the proportions of Catholics and Protestants. We thus carried out an ecological study by collating publicly available online data for 135 countries. We additionally gathered within-country data for 5 Western nations: France, Ireland, the UK, Canada and the USA. We found that, in Western countries, the proportion of Catholics was negatively correlated with the rate of breast feeding. This was also observed within countries in France, Ireland, the UK and Canada. In the USA, where breast feeding rates vary hugely between states, race was an important confounder. Interestingly, we also found the correlation in non-Hispanic whites. All our findings hold even when we account for wealth indicators, such as gross domestic product per capita. (more…)
Author Interviews, Dermatology, JAMA, Pediatrics / 07.12.2016

MedicalResearch.com Interview with: Steve Xu MD, MSc Resident Physician Department of Dermatology Northwestern Feinberg School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Given the limited data on the effectiveness or safety of the different moisturizers examined in the study, how much do you think parents should decide what to use on their babies based on the "cost-effectiveness" determined in this study? Would you just say cheapest is best since we don't know how well these things work? Or what's the message? Price. Petrolatum is an extremely effective moisturizer. It also happens to be one of the most affordable. Unlike adults, I don't suspect newborns will complain too much about the greasiness of petrolatum. They're less concerned that their work clothes will get ruined. They are less likely to care about cosmetic elegance. I also will say that petrolatum is less likely to include any artificial fragrances, preservatives that could serve as irritants or allergens in the future. That's an added bonus. (more…)
Author Interviews, Biomarkers, Pediatrics, Pulmonary Disease / 02.12.2016

MedicalResearch.com Interview with: Prof. Henrik Verder Department of Pediatrics Holbaek University Hospital Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Response: Respiratory Distress Syndrome (RDS) is a major cause of mortality and morbidity in premature infants. It can be effectively treated with surfactant, a therapy which reduces the effort needed to expand the lungs during inspiration and allow gas exchange to take place. Early surfactant treatment can help prevent the onset and impact of RDS, however, prophylactic treatment has been shown to be harmful and only necessary in half of all pre-term infants. This study provided data validating the efficacy of a lung maturity test (LMT) in identifying infants at risk of respiratory distress syndrome (RDS) who could benefit from early surfactant treatment.

MedicalResearch.com Interview with: Dr Katie (Katherine) Twomey ESRC Future Research Leaders Fellow, Lancaster University Senior Research Associate, ESRC International Centre for Language and Communicative Development (LuCiD)   MedicalResearch.com: What is the background for this study? What are the main findings? Response: Although we know that toddlers can quickly work out what new words mean, it's not yet clear exactly how they do it. For example, when they see a new object alongside their favorite toy truck and hear a new word "block", we know that they will link "block" to the new object. They could do this by thinking in detail about what they already know, for example "if my toy is called "truck", then "block" must be the name of the new object". Equally, however, they could quickly link the new word to the new object without thinking about it in-depth. We tested this second possibility using iCub, a humanoid robot which learns by making quick associations between what it sees and what it hears, without the ability to think in detail about what it already knows. We replicated two studies of toddlers' early word learning with iCub and found that even though it can only learn through making simple links between words and objects, it behaved exactly as children did in the original experiments.

Author Interviews, Flu - Influenza, Pediatrics, Science, UCLA / 28.11.2016

MedicalResearch.com Interview with: Katelyn M. Gostic and Monique Ambrose Department of Ecology and Evolutionary Biology University of California Los Angeles MedicalResearch.com: What is the background for this study? What are the main findings? Monique Ambrose: Influenza pandemics pose a serious, recurrent threat to human public health. One of the most probable sources of future pandemic influenza viruses is the pool of influenza A virus (IAV) subtypes that currently circulate in non-human animals. It has traditionally been thought that the human population is immunologically naïve and unprotected against these unfamiliar subtypes. However, our work suggests that an individual ‘imprints’ to the influenza A virus (IAV) encountered in early childhood in such a way that they retain protection against severe disease if they later encounter a novel IAV subtype that belongs to the same genetic group as their first exposure. Our research looked at human cases of H5N1 and H7N9, two avian IAV subtypes of global concern, to investigate what factors most strongly predicted risk of severe disease. The most striking explanatory factor was childhood IAV imprinting: our results suggest that individuals who had childhood imprinting on an IAV in the same genetic group as the avian IAV they encountered later in life experienced 75% protection against severe disease and 80% protection against death.

Author Interviews, Autism, Emory, Pediatrics / 25.11.2016

MedicalResearch.com Interview with: Warren Jones, PhD Director of Research, Marcus Autism Center Children's Healthcare of Atlanta CHOA Distinguished Chair in Autism Asst. Professor, Dept. of Pediatrics Emory University School of Medicine Atlanta, Georgia 30329 MedicalResearch.com: What is the background for this study? What are the main findings? Response: These results help clarify an important and longstanding question in autism: why do children with autism look less at other people’s eyes? Two ideas for reduced eye contact in autism have been proposed: - One idea is that children with autism avoid eye contact because they find it stressful and negative. - The other idea is that children with autism look less at other people’s eyes because the social cues from the eyes are not perceived as particularly meaningful or important. This study is important because each idea reflects a very different understanding of what autism is. And maybe even more importantly, each idea reflects a very different view about the right treatment approach to autism and to reduced eye contact in autism. To answer this question, we used eye-tracking technology to study how 86 children with and without autism paid attention to other people’s eyes. Children were tested when they were just two years old, at their time of initial diagnosis. (more…)
Author Interviews, Neurological Disorders, Ophthalmology, Pediatrics / 23.11.2016

MedicalResearch.com Interview with: Marius George Linguraru, DPhil, MA, MB Principal Investigator Associate Professor of Pediatrics and Radiology George Washington University School of Medicine and Health Sciences Children’s National Health System Washington, DC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Neurofibromatosis type 1 (NF1) is the most common cancer predisposition syndrome affecting the central nervous with an incidence of one in 3,000 births. Nearly one in five children with NF1 develops an optic pathway glioma (OPG), a low-grade tumor of the anterior visual pathway (i.e., optic nerves, chiasm and tracts). These tumors are not amenable to surgical resection and can cause permanent vision loss ranging from a mild decline in visual acuity to complete blindness. Only half of children with NF1-OPGs will experience vision loss, typically between 1 to 6 years of age. The other half will never lose vision or require treatment. All previous studies have consistently demonstrated that the change in NF1-OPG size is not related to the clinical outcome. For example, the optic pathway glioma size may be stable or even decrease, yet the vision will decline. Alternatively, the OPG size may increase, yet the clinical outcome remains stable or even improves. As no imaging or clinical features can identify which children with NF1-OPGs will ultimately lose vision, clinicians struggle to follow these children and decide when to intervene. We used quantitative imaging technology to accurately assess in magnetic resonance imaging (MRI) the total volume of OPGs in NF1. We also determined the retinal nerve fiber layer thickness in these children, a measure of axonal degeneration and an established biomarker of visual impairment. The results were outstanding, as we showed for the first time that the volume of an optic pathway glioma is indeed correlated with the likelihood of vision loss in children with Neurofibromatosis type 1.

MedicalResearch.com Interview with: Charles Opondo, BPharm MSc PhD. Researcher in Statistics and Epidemiology National Perinatal Epidemiology Unit Nuffield Department of Population Health University of Oxford Oxford MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our study measured fathers’ involvement in their child’s upbringing in infancy by looking at their emotional response to their child (e.g. feeling confident with the child, making a strong bond with the child), how involved they were in childcare (e.g. changing nappies, playing, night feeding, and also general care tasks around the house such as meal preparation) and their feelings of being a secure in their role as a parent (e.g. feeling included by mother in childcare, not feeling inexperienced with children). We found that the children of fathers who scored highly in terms of their emotional response and feeling like a secure parent were less likely to have symptoms of behavioural problems when they were 9 or 11 years. However, fathers being more involved in direct childcare did not seem to affect the child’s risk of having later behavioural problems. (more…)

MedicalResearch.com Interview with: Liping Pan, MD MPH Centers for Disease Control and Prevention Atlanta, GA MedicalResearch.com: What is the background for this study? What are the main findings? Response: This CDC report is the first to use the WIC Participant Characteristic (WIC PC) data from the USDA to monitor trends in obesity among young children aged 2 to 4 years in the WIC program. The main findings of the study are: • 34 of 56 (61%) WIC state agencies reported modest decreases in obesity among young children from 2010 to 2014. • From 2000 to 2010, the prevalence of obesity among 2-4 year olds increased from 14.0% to 15.9%, then dropped to 14.5% from 2010 to 2014. • Obesity prevalence varied by state, ranging from 8.2 percent in Utah to 20.0 percent in Virginia. • From 2010 to 2014, obesity prevalence decreased among all major racial/ethnic groups, including non-Hispanic whites, non-Hispanic blacks, Hispanics, American Indians/Alaska Natives, and Asians/Pacific Islanders. • From 2000 to 2014, obesity prevalence decreased significantly among Asian/Pacific Islanders, from 13.9 percent to 11.1 percent.

Author Interviews, Autism, JAMA, Pediatrics / 20.11.2016

MedicalResearch.com Interview with: Dr. Melanie Penner, MD FRCP (C) Clinician investigator and developmental pediatrician Holland Bloorview Kids Rehabilitation Hospital  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Studies have shown that accessing intensive behavioral intervention (IBI) services at younger ages is associated with improved outcomes for children with autism spectrum disorder (ASD). In Ontario, Canada, children wait years to access publicly-funded IBI. This analysis estimated costs and projected adult independence for three IBI wait time scenarios: the current wait time, a wait time reduced by half, and an eliminated wait time. The model inputs came from published literature. The main findings showed that eliminating the wait time generated the most independence and cost the least amount of money to both the government and society. With no wait time for intensive behavioral intervention, the government would save $53,000 (2015 Canadian dollars per person) with autism spectrum disorder over their lifetime, and society would save $267,000 (2015 Canadian dollars).

MedicalResearch.com Interview with: Toby Litovitz, MD Executive & Medical Director, National Capital Poison Center Professor of Emergency Medicine, Georgetown University Clinical Professor of Emergency Medicine The George Washington University Washington DC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Over the past decade, a dramatic and persistent rise in the severity of swallowed batteries has been attributed to increased use of 20 mm diameter lithium coin cell batteries. With its larger diameter compared to traditional button cells, these cells get stuck in the esophagus of small children. There the greater voltage (3 V for lithium coin cells rather than 1.5 V for traditional button batteries), causes these cells to rapidly generate an external current that hydrolyzes tissue fluids, generating hydroxide and causing severe burns, injury and even death. Severe or fatal complications include perforations of the esophagus, tracheoesophageal fistulas, recurrent laryngeal nerve damage leading to vocal cord paralysis, spondylodiscitis, strictures and aortoesophageal fistulas – the latter nearly always fatal.

MedicalResearch.com Interview with: Stuart L. Goldstein, MD, FAAP, FNKF Clark D. West Endowed Chair Professor of Pediatrics University of Cincinnati College of Medicine Director, Center for Acute Care Nephrology | Associate Director, Division of Nephrology Medical Director, Pheresis Service | Co-Medical Director, Heart Institute Research Core Division of Nephrology and Hypertension | The Heart Institute Cincinnati Children’s Hospital Medical Center Cincinnati, OH 45229 MedicalResearch.com: What is the background for this study? What are the main findings? Response: This was a prospective international multi-center assessment of the epidemiology of acute kidney injury in children in young adults. Over 5,000 children were enrolled from 32 pediatric ICUs in 9 countries on 4 continents. The main findings are: 1) Severe AKI, defined by either Stage 2 or 3 KDIGO serum creatinine and urine output criteria carried an incremental risk of death after adjusting for 16 co-variates. 2) Patients with AKI by low urine output would have been misclassified as not having AKI by serum creatinine criteria and patients with AKI by urine output criteria have worse outcomes than patients with AKI by creatinine crtieria. 3) Severe AKI was also associated with increased and prolonged mechanical ventilation use, increased receipt of dialysis or ECMO (more…)
Author Interviews, Brigham & Women's - Harvard, OBGYNE, Pediatrics / 18.11.2016

MedicalResearch.com Interview with: Melissa C. Bartick, MD, MSc Department of Medicine Cambridge Health Alliance Harvard Medical School Cambridge, MA MedicalResearch.com: What is the background for this study? Response: This is the first study ever to combine maternal and pediatric health outcomes from breastfeeding into a single model. We had published a cost analysis of suboptimal breastfeeding for pediatric disease in 2010, which found that suboptimal breastfeeding cost the US $13 billion in costs of premature death costs and medical expenses, and 911 excess deaths.
