Author Interviews, CDC, OBGYNE, Pediatrics, Race/Ethnic Diversity / 17.07.2017

MedicalResearch.com Interview with: Dr. Erica H. Anstey PhD Division of Nutrition, Physical Activity and Obesity National Center for Chronic Disease Prevention and Health Promotion Immunization Services Division National Center for Immunization and Respiratory Diseases CDC MedicalResearch.com: What is the background for this study? Response: The American Academy of Pediatrics (AAP) recommends that infants are breastfed exclusively for about the first 6 months and that breastfeeding continue for at least 12 months, and thereafter for as long as mother and baby desire. Although breastfeeding initiation and duration rates have increased overall in the United States, breastfeeding rates vary by geographic location, socioeconomic, and race/ethnic groups. Breastfeeding initiation and duration have been historically and consistently lower among black infants compared with white and Hispanic infants. There are many factors that influence a woman’s decision to start and continue breastfeeding. These include knowledge about breastfeeding, cultural and social norms, family and social support, and work and childcare environments. Some barriers to breastfeeding are disproportionately experienced by black women, including earlier return to work, inadequate receipt of breastfeeding information from providers, and lack of access to professional breastfeeding support.

Author Interviews, Pediatrics, Primary Care, Vaccine Studies / 14.07.2017

  MedicalResearch.com Interview with: S. Hughes Melton, MD, MBA, FAAFP AAFP Foundation president MedicalResearch: What is the background for this initiative? What are the main vaccinations that teens should have?  Response: The Centers for Disease Control and Prevention (CDC) recommends adolescents receive four immunizations – two of which are administered as multi-dose series – to help protect against meningococcal meningitis caused by serogroups A, C, W and Y; human papillomavirus (HPV); tetanus, diphtheria and pertussis (Tdap); and influenza (flu).1 Despite these recommendations, millions of teens remain vulnerable to serious infectious disease.2,3 Family physicians are well equipped to immunize their patients against a host of common infectious diseases and improve public health. However, discussing teen vaccinations during annual appointments may present challenges due to other issues teens and their parents/guardians may be focused on at this age. The American Academy of Family Physicians Foundation (AAFP Foundation) launched Highlight on VACCINATIONS 4 TEENS to help remind family physicians and their care teams to make immunization a priority at these key appointments for teens.

Author Interviews, Depression, Gender Differences, Pediatrics / 12.07.2017

MedicalResearch.com Interview with: Jie-Yu Chuang PhD Department of Psychiatry University of Cambridge Cambridge, United Kingdom  MedicalResearch.com: What is the background for this study? Response: Men and women appear to suffer from depression differently, and this is particularly striking in adolescents. By 15 years of age, girls are twice as likely to suffer from depression as boys. There are various possible reasons for this, including body image issues, hormonal fluctuations and genetic factors, where girls are more at risk of inheriting depression. However, differences between the sexes don't just involve the risk of experiencing depression. Men are more liable to suffer from persistent depression, whereas in women depression tends to be more episodic. Compared with women, depressed men are also more likely to suffer serious consequences from their depression, such as substance abuse and suicide. Despite this, so far, most researchers have focused on depression in women, likely because it is more common. As a result, we'd like to make people more aware of the sex difference issue in depression. (more…)
Author Interviews, JAMA, Nutrition, Pediatrics / 10.07.2017

MedicalResearch.com Interview with: Dr. Anne-Louise M. Heath and Professor Rachael Taylor Co-Principal Investigators for the BLISS study. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Conventional approaches to complementary feeding generally advise parents to spoon-feed their infant pureed foods, gradually progressing to greater variety and texture so that by the time the infant is one year of age, they are eating more or less what the family does. Baby-led weaning (BLW) is an alternative approach where the infants feeds themselves right from the start of complementary feeding. Because children of this age cannot use utensils, this means hand-held foods are necessary. Advocates of BLW suggest that children have a lower risk of obesity because they remain in control of their own food intake, but research examining this issue directly is scarce. Health professionals have also expressed concern that BLW might put the infant at increased risk of iron deficiency (parents might avoid red meat for fear of the infant choking, and iron-fortified cereals are not easy for the infant to feed themselves), growth faltering (if only low energy foods are offered) and choking (from the infant feeding themselves ‘whole’ foods). Our study therefore examined a version of BLW that had been modified to address these issues (called BLISS - a Baby-Led Introduction to SolidS). Two hundred families took part in our 2-year intervention, with half following traditional feeding practices and half receiving guidance and support to follow our BLISS approach. We found that BLISS children were not less likely to be overweight than those following traditional feeding practices, nor was growth faltering an issue. BLISS child ate about the same amount of food as control children, and their ability to eat to appetite was not different either. However, it seems that children following a baby-led approach to complementary feeding are less fussy about food, and have a healthier attitude to food, which might make a difference to their health long term.

MedicalResearch.com Interview with: Seetha Shankaran, M.D. Professor, Neonatology Wayne State University School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: The study was performed because infants with moderate or severe hypoxic-ischemic encephalopathy (abnormal neurological exam within 6 hours of birth due to lack of blood and oxygen supply to the brain at birth) have rates of death or survival with disability that were still high in spite of current intensive care including hypothermia. Whole-body hypothermia, cooling the infant for 72 hours at a depth of 33.5°C that was performed by the Neonatal Research Network funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development was the first trial of this therapy in the USA. We found that hypothermia therapy did decrease the rate of death or survival with disability from 62 to 44%. Since 44% is still high we wanted to see if longer cooling or deeper cooling or both would reduce this rate. This was a randomized controlled clinical trial to examine whether longer cooling or deeper cooling or both reduced the rate of death or survival with disability among full term neonates with hypoxic-ischemic encephalopathy. The study lasted from October of 2010 to January 2016. 364 infants were enrolled. Neonates were randomly assigned to 4 groups of cooling therapy and the major findings were that neither longer cooling nor deeper cooling nor both were more superior to cooling for 72 hours at 33.5°C. Our results were surprising because at the time we planned this study there were reports from animal model studies that longer/deeper cooling were more protective to the brain. (more…)

MedicalResearch.com Interview with: Michelle S. Wong PhD Department of Health Policy and Management Johns Hopkins School of Public Health Baltimore, Maryland MedicalResearch.com: What is the background for this study? Response: As background, there haven't been many studies on how fathers might influence overweight or obesity in their children. Unsurprisingly most of the research has focused on the mothers' influence. Existing studies on fathers have focused on the relationship between their parenting practices (e.g., discipline), as well as feeding and physical activity behaviors, with child overweight or obesity. A few studies found that some father feeding practices were related to higher child BMI, but we don’t know whether fathers’ general caregiving matters. (more…)
Author Interviews, Hearing Loss, Pediatrics / 23.06.2017

MedicalResearch.com Interview with: Peter Carew Lead author, MCRI PhD student Clinician The University of Melbourne MedicalResearch.com: What is the background for this study? Response: The age at diagnosis of a congenital hearing loss has dropped over time. This has allowed for earlier fitting of amplification (hearing aids, cochlear implants) and earlier access to education intervention programs, all intended to lessen the impact of hearing loss on development. Much research has focused on the outcomes achieved by children with severe and profound losses, but relatively little attention has been given to milder hearing losses (mild and moderate). Despite this lack of evidence, we are observing children with mild loss being fitted with hearing aids earlier than ever before. From a historical age of fitting not uncommonly at 2 years of age or older, today the largest number of children under 12 months who receive a hearing aid for the first time in Australia have a mild hearing loss in their better hearing ear. To this end, clinical practice may have jumped ahead of the evidence in terms of understanding any benefits children with mild hearing loss receive from having hearing aids earlier. (more…)

MedicalResearch.com Interview with: David C. Grossman, M.D., M.P.H. US Preventive Services Task Force Chair Senior Investigator, Kaiser Permanente Washington Health Research Institute Senior Associate Medical Director, Market Strategy & Public Policy Kaiser Permanente Washington Physician, Washington Permanente Medical Group, Pediatrics MedicalResearch.com: What is the background for this recommendation? Response: Recognizing that obesity is a nation-wide health problem, affecting approximately 17% of 2-to 19-year-old children and adolescents in the U.S., the Task Force finalized its recommendation on screening for obesity in children and adolescents and the benefits and harms of weight management interventions. The Task Force found sufficient evidence to recommend screening for obesity in children and adolescents age 6 years and older and then offering or referring those who are found to be obese comprehensive, intensive behavioral interventions to manage their weight and improve overall health. MedicalResearch.com: What are the potential benefits and harms of early screening and intervention for obesity in children? Response: The Task Force found that intensive behavioral interventions for children and adolescents who have obesity can result in benefits of improvement in weight status for up to 12 months’ post-intervention. Additionally, the evidence indicated very little harm from screening and comprehensive, intensive behavioral interventions. This is due to likely minimal harms of using BMI (body mass index), the absence of reported harms of behavioral interventions, and the noninvasive nature of the programs. (more…)
Author Interviews, Global Health, Infections, Pediatrics / 19.06.2017

MedicalResearch.com Interview with: Aleksandra Jakubowski, MPH PhD candidate Department of Health Policy and Management Gillings School of Global Public Health University of North Carolina at Chapel Hill MedicalResearch.com: What is the background for this study? Response: The US President’s Malaria Initiative (PMI) provides approximately $600 million annually to fund implementation of key evidence-based malaria prevention and treatment interventions, including insecticide treated nets (ITNs), artemisinin-based combination therapy (ACT), and indoor residual spraying (IRS) to populations in 19 recipient countries in sub-Saharan Africa (SSA). Despite this considerable investment, no study to date has evaluated the impact of PMI on population health outcomes. Previous evaluations have noted improved health outcomes in PMI countries, but comparison groups are needed to establish whether these changes were beyond the declining trends in mortality observed in the rest of the region. Our study sought to generate objective evidence for policy makers about the role this US-funded malaria aid program may have played in curbing child mortality in SSA. We used a quasi-experimental design known as difference-in-differences to compare trends in health outcomes in PMI-recipient vs. PMI non-recipient countries. We analyzed publicly-available data from 32 countries in SSA spanning a period that included about ten years before and after the introduction of the program. (more…)
Addiction, Author Interviews, JAMA, Opiods, Pediatrics / 19.06.2017

MedicalResearch.com Interview with: Scott Hadland, MD, MPH, MS Youth Addiction Specialist Assistant Professor of Pediatrics Boston University School of Medicine Director, Urban Health and Advocacy Track, Boston Children’s Hospital and Boston Medical Center Associate Program Director, Boston Combined Residency Program in Pediatrics, Boston Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: Almost no data have been available on this topic to date.  A recent study showed that teens in subspecialty treatment for opioid addiction were significantly less likely than adults to receive a medication.  Our study was the first to comprehensively look across the health care system, including looking at adolescents and young adults diagnosed with opioid use disorder in outpatient clinics, emergency departments, and inpatient hospitals. We had three important findings.  First, looking at a large sample of 9.7 million adolescents and young adults between the age of 13 and 25 years, we found that the number of youth diagnosed with opioid use disorder increased six-fold from 2001 to 2014.  This is perhaps not surprising given the national opioid crisis we know to be occurring. Second, we found that only a minority of youth (1 in 4) received buprenorphine or naltrexone, the two medications available for opioid addiction that can be prescribed in usual medical settings.  These two medications are evidence-based and their use is recommended by the American Academy of Pediatrics.  Utilizing them is critical to ensure that we offer effective treatment early in the life course of addiction, which can help prevent the long-term harms of addiction. Third, we found significant differences in who received medications.  Whereas approximately 1 in 3 young adults in our study received a medication, only 1 in 10 of the 16- and 17-year-olds we studied received one, and among adolescents under 15 years of age, 1 in 67 received a medication.  Females were less likely than males to receive medications, as were black youth and Hispanic youth relative to white youth.

MedicalResearch.com Interview with: Cuilin Zhang MD, PhD Senior Investigator, Epidemiology Branch Division of Intramural Population Health Research NICHD/National Institutes of Health Bethesda, MD 20817  MedicalResearch.com: What is the background for this study? Response: Refined grains with a high glycemic index and reduced fiber and nutrient content have been linked to increased adiposity and higher risk of metabolic syndrome among adults. Despite these differences and the growing body of literature on the link between maternal diet/nutrition during pregnancy and subsequent offspring health consequences throughout the lifespan, little is known about the intergenerational impact of refined-grain intake during pregnancy on long-term cardio-metabolic outcomes in the offspring.

MedicalResearch.com Interview with: Dr. Malcolm Sears, Professor MB, ChB, FRACP, FRCPC, FAAAAI Co-director of the CHILD Study Division of Respirology, Department of Medicine, McMaster University MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Canadian Healthy Infant Longitudinal Development (CHILD) Study is a longitudinal birth cohort study commenced in 2008 with 3,495 families across Canada.  We recruited the mothers during pregnancy and are following their children to age 5 with the intent of determining the underlying developmental causes of allergy and asthma. In the current analysis, we have looked at the relationship between the timing of first introduction of three “allergenic” foods (milk products, egg and peanut) and the likelihood of sensitization to these foods at age 1 year.  We found that earlier introduction was associated with a reduced risk of sensitization, which is consistent with some recent randomized controlled trials.  For instance, infants who avoided cow’s milk product in their first year of life were nearly four times as likely to be sensitized to cow’s milk compared with infants who did consume cow’s milk products before age 12 months.  Similarly, infants who avoided egg or peanut in the first year were nearly twice as likely to be sensitized to those foods compared to infants who consumed them before 12 months of age.

Abuse and Neglect, Addiction, Alcohol, Pediatrics / 19.06.2017

MedicalResearch.com Interview with: Tammy E. Corr, D.O. Assistant Professor of Pediatrics Division of Newborn Medicine Penn State Hershey College of Medicine MedicalResearch.com: What is the background for this study? Response: Recent literature has revealed hospital charges related to neonatal abstinence syndrome (NAS) have increased. However, there are no data available regarding costs of an NAS admission. Because charges are variable and influenced by a number of factors, provider costs to care for a patient offer more meaningful information. Therefore, we endeavored to determine the incidence of NAS in the United States and estimate the total annual costs and hospital length of stay for an neonatal abstinence syndrome admission as well as the incremental costs and hospital days of admission for an NAS patient compared to a non-NAS admission.

MedicalResearch.com Interview with: David Kerr PhD Associate professor in the School of Psychological Science College of Liberal Arts Ohio State University  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Oregon legalized sale and use of marijuana for recreational purposes and the part of the law (regarding use) took effect in July 2015. However, there have been no controlled studies of which we’re aware of the possible effects of the Oregon law that take into account the trends toward increased marijuana use across the country and differences in use rates between states that predated the law. We used survey data on college students in Oregon and in 6 states without recreational legalization to examine the issue. (more…)
Author Interviews, Genetic Research, Pediatrics / 14.06.2017

MedicalResearch.com Interview with: Charlotte Cecil, PhD ESRC FRL Fellow Edward Barker, PhD Lab Director, DEVELOPMENTAL PSYCHOPATHOLOGY LAB Department of Psychology Institute of Psychiatry, Psychology& Neuroscience King's College London MedicalResearch.com: What is the background for this study? What are the main findings? Response: Conduct problems (CP) are the most common reason for child treatment referral in the UK, costing an estimated £22 billion per year. Children with CP engage in a range of aggressive and antisocial behaviours (e.g. fighting, stealing, lying), that affect their ability to follow rules and adapt to society, do well in school, and form healthy relationships. Those who do not receive treatment are also at increased risk for many negative outcomes in adulthood, including lower job prospects and earnings, more contact with the police and a lower quality of life. Therefore, it is important to understand how CP develop in the first place, in order to create more effective prevention and intervention strategies. Studies have found that children who develop conduct problems before the age of 10 (early-onset CP) are at greatest risk for poor outcomes across the lifespan. Compared to other children, those showing early-onset CP tend to have experienced more adversity in early life (e.g. prenatal stress, poverty) as well as having more genetic risk. However, little is known about about how genetic factors interact with environmental influences - especially during foetal development - to increase the risk for early-onset conduct problems. (more…)
Author Interviews, Diabetes, Pediatrics / 13.06.2017

MedicalResearch.com Interview with: Prof. Dr. Thomas Danne Chief Physician Diabetology, Endocrinology and General Pediatrics and Clinical Researc Kinder und Junden Krankenhaus MedicalResearch.com: What is the background for this study? What are the main findings? Response: The double-blind, placebo controlled, Phase 3 study known as inTandem2 randomized 782 adult patients from 99 sites in the EU and Israel with type 1 diabetes on insulin pump or multiple daily injection therapy who had an A1C level entering the study between 7.0% and 11.0%. The three-arm study evaluated two doses of sotagliflozin, 200mg and 400mg, each taken once daily before the first meal of the day, against placebo. Prior to randomization, insulin was optimized for all patients over a six-week period, with the objective of improving glycemic control using insulin alone. After completion of this optimization period, patients were maintained on optimized insulin and randomized to one of two doses of sotagliflozin or placebo, and their baseline, post-optimization A1C was measured. The mean baseline A1C levels after the six-week optimization period were 7.8%, 7.7% and 7.7% for patients randomized to the placebo, 200mg and 400mg arms, respectively (A1C was 8.4% across all dose arms prior to insulin optimization). The primary endpoint of the study was change in A1C from baseline after a 24-week period of treatment. The trial has a double-blind long term extension of 28 weeks, with a total treatment duration of 52 weeks. There were 258 patients in the placebo arm, 261 patients in the 200mg dose arm and 263 patients in the 400mg dose arm. The overall mean placebo-adjusted A1C reduction at week 24 was 0.36% in the 200mg dose arm (p<0.001) and 0.35% in the 400mg dose arm (p<0.001). In response to regulatory input, a secondary endpoint to measure “net clinical benefit” was defined for this study as the proportion of patients at week 24 who achieved the standard of care A1C goal of less than 7.0% without any episode of severe hypoglycemia or DKA. 15% of patients in the placebo arm, 32% in the 200 mg dose arm and 32% in the 400mg dose arm achieved this endpoint (p<0.001 for both treatment arms).

MedicalResearch.com Interview with: Mackenzie M. Herzog, MPH PhD Candidate, Injury Epidemiology The University of North Carolina at Chapel Hill  MedicalResearch.com: What is the background for this study? Response: In 1999, a study by Arendt et al. reported that women were more likely to tear their ACL than men while playing the same sport. Since then, numerous studies have investigated this sex difference in ACL injury, and many prevention programs targeting youth athletes have been developed and tested. Although randomized trials have demonstrated the value of injury prevention programs in reducing the risk of ACL injury, the overall impact of these programs has not been examined in the general population. Our study investigated the net impact of research and prevention efforts over nearly 20 years in reducing ACL injuries by assessing time trends of ACL reconstruction, a consequence of ACL injury, among commercially-insured individuals in the United States.

MedicalResearch.com Interview with: Dr Michelle Taylor PhD Senior Research Associate in Epidemiology MRC Integrative Epidemiology Unit (IEU) School of Social and Community Medicine University of Bristol Bristol UK MedicalResearch.com: What is the background for this study? Response: Many previous studies have looked at adolescent cannabis use, however most of these look at use at a single time point, for example whether an individual has ever used cannabis at age 16 years, or how regularly a person uses cannabis at age 18. However, as young people do not initiate use at the same time or follow the same pattern of use, using measures at a single time point does not always tell the whole story. We used a form of statistical modelling using data taken over the course of adolescence to try and characterise underlying patterns of cannabis use across adolescence. We used data from the Avon Longitudinal Study of Parents and Children which had information on cannabis use at six time points between the ages of 13 and 18 years. (more…)

MedicalResearch.com Interview with: Raylene Reimer, PhD, RD Professor, Faculty of Kinesiology University of Calgary Department of Biochemistry & Molecular Biology Cumming School of Medicine Full Scientist Alberta Children's Hospital Research Institute MedicalResearch.com: What is the background for this study? Response: The human gut microbiota is a complex and dynamic population of microorganisms that benefit the human host through a variety of microbial activities (e.g. production of vitamins, immune regulation, utilization of dietary fiber). Despite these benefits however, it is now recognized that disruption of the microbiota (dysbiosis) can upset homeostasis and contribute to diseases such as obesity and type 2 diabetes. Manipulation of the gut microbiota to prevent or treat chronic disease is now an area of intense scientific and clinical interest. Dietary prebiotics, such as inulin and oligofructose, are used selectively by host microorganisms to confer a health benefit. Prebiotics have previously been shown to reduce body fat, improve appetite control and reduce blood glucose in adults with overweight or obesity. (more…)
Author Interviews, Biomarkers, Pediatrics, Pulmonary Disease / 07.06.2017

MedicalResearch.com Interview with: Jegen Kandasamy MD Division of Neonatology Assistant Professor/Director, Rare Disease Program and Congenital Anomalies Program University of Alabama at Birmingham Birmingham, Alabama  MedicalResearch.com: What is the background for this study? Response: Preterm infants, especially those that are born with a birth weight of 750 grams or less, are prone to a lung disease called bronchopulmonary dysplasia (BPD) because the development of lungs in these infants takes place in an environment that has more oxygen than that available in utero. Recently, pulmonary blood vessel growth and function has been hypothesized to play a causal role in the pathogenesis of BPD. Vascular endothelial cell function has been shown to affect hyperoxia-induced lung damage in animal studies. An important source of human vascular endothelial cells is the umbilical cord of newborn infants. These human umbilical venous endothelial cells (HUVEC) have been used to measure endothelial cell function in various diseases but never in diseases related to the newborn infants from whom they were derived. In addition, the mitochondria in various cells in our body respond to oxygen toxicity by creating, as well as consuming, reactive oxygen species (ROS) that mediate most of the effects of oxygen-induced damage. Therefore, we designed this study to measure mitochondrial function in vascular endothelial cells obtained from the umbilical cords of prematurely born infants at the time of their birth. We then compared these mitochondrial functional measures between infants who later died or developed BPD versus those who survived without BPD. (more…)

Chan School of Public Health Boston, MA MedicalResearch.com: What is the background for this study? Response: We designed this study to test the effectiveness of two interventions that linked clinical and community approaches in improving childhood body mass index (BMI) and obesity prevalence. Another important question we set out to understand was whether there were outcomes aside from BMI and obesity that mattered most to families of children with obesity. (more…)

MedicalResearch.com Interview with: Suniya S. Luthar, Ph.D. Foundation Professor of Psychology Arizona State University Professor Emerita Columbia University's Teachers College President-elect, American Psychological Association's Div.7 (Developmental) MedicalResearch.com: What is the background for this study? What are the main findings? Response: Over the last 20 years, we have found that kids in high achieving schools report higher use of drugs and alcohol than do their counterparts in national normative samples. This particular study was the first in which we followed up samples of high school students through young adulthood, to track levels of substance abuse and addiction. Our findings showed consistently elevated use of various substances across the years. Of greatest concern were diagnoses of dependence (that is, not just abuse of substances but actual addiction to them); among 26 year olds, rates of these diagnoses were two to three times those in national norms.

MedicalResearch.com Interview with: Michael S. Dunbar, PhD Associate Behavioral Scientist RAND Corporation MedicalResearch.com: What is the background for this study? Response: Sexual minority college students suffer from mental health problems like anxiety and depression at higher rates than their heterosexual peers. If they aren’t addressed, these types of issues can have serious negative effects on things like academic achievement, employment, and quality of life –among others. This study analyzed information from a survey about mental health needs and use of mental health services. The survey was completed by over 33,000 students from nine University of California campuses, nine California State University campuses and 15 California community colleges. The results were weighted to help reflect California’s college student population. (more…)
Author Interviews, Autism, Mineral Metabolism, Nature, Pediatrics / 05.06.2017

MedicalResearch.com Interview with: Manish Arora, PhD Associate Professor Environmental Medicine & Public Health Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? What are the main findings? Response: Autism has both genetic and environmental risk factors. Our aim was to study if exposure to toxic metals, such as lead, or disruptions in the uptake of essential nutrient elements such as manganese or zinc would be related to autism risk. Furthermore, we were interested in not only understanding how much exposure had taken place but also which developmental periods were associated with increased susceptibility to autism risk. Researchers suspect that the risk factors for autism start early in life, even prenatally, but measuring in utero exposures is technically very challenging. We used a newly developed technique that uses lasers to map growth rings in baby teeth (like growth rings in trees) to reconstruct the history of toxic metal and essential nutrient uptake. We applied this technology in samples collected from twins, including twins who were discordant for autism. This allowed us to have some control over genetic factors. We found that twins with autism had higher levels of lead in their teeth compared to their unaffected twin siblings. They also had lower levels of zinc and manganese. The lower uptake of zinc was restricted to approximately 10 weeks before birth to a few weeks after birth, indicating that as a critical developmental period. (more…)

MedicalResearch.com Interview with: Gary 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: Lawn mowers continue to be an important source of serious pediatric morbidity in the United States (US) with initial treatment of pediatric lawn mower-related injuries costing about $90 million annually. The long-term physical, psychological, and financial effects of these traumatic injuries can be devastating for those injured and for their families. This study comprehensively analyzes data over a 25-year period using a nationally representative database to evaluate the epidemiologic characteristics, including mechanism of injury, of lawn mower-related injuries to children in the US. It also provides a discussion of relevant injury prevention strategies. (more…)

MedicalResearch.com Interview with: Jacqueline Pasulka, OMS II Des Moines University College of Osteopathic Medicine , Des Moines , IA Division of Pediatric Orthopaedic Surgery & Sports Medicine, Ann & Robert H. Lurie Children's Hospital of Chicago , Chicago , IL MedicalResearch.com: What is the background for this study? What are the main findings? Response: In this study young athletes were recruited from both sports medicine and general practice clinics and were asked to complete surveys reporting on their sports participation, training patterns, and any sports-related injuries they had over the previous six months. We focused this study on the subset of athletes who met the criteria for being a single-sport specialized athlete based on their reported participation in only one sport and training for eight months or more during the year for that sport. Athletes participating in individual sports were more likely to be single-sport specialized than their team sport peers, and they also reported an earlier age at which they began specializing in their sport. Additionally, injury types differed among these two groups as single-sport specialized athletes in individual sport athletes had a greater proportion of overuse injuries, while single-sport specialized athletes in team sport athletes had a greater proportion of acute injuries.

MedicalResearch.com Interview with: Antony Loebel, M.D. Executive Vice President and Chief Medical Officer Sunovion, Head of Global Clinical Development Sumitomo Dainippon Pharma Group MedicalResearch.com: What is the background for this study? What are the main findings? In the six-week, randomized, double-blind, placebo-controlled study, 347 children and adolescents (10 to 17 years of age) with bipolar depression received once-daily LATUDA flexibly dosed (20-80 mg/day) or placebo.The Phase 3 clinical study met its primary endpoint, showing statistically significant and clinically meaningful improvement in symptoms compared to placebo. LATUDA was generally well tolerated, with minimal effects on weight and metabolic parameters. The primary efficacy endpoint was change from baseline to week 6 on the Children Depression Rating Scale, Revised (CDRS-R) total score. LATUDA was associated with statistically significant and clinically meaningful improvement in bipolar depression symptoms compared to placebo, based on CDRS-R total score (-21.0 vs. -15.3; effect size = 0.45; p<0.0001) and CGI-BP-S score for depression (-1.49 vs. -1.05; effect size = 0.44; p<0.001). LATUDA also demonstrated statistically significant improvement on secondary efficacy endpoints. The most common treatment-emergent adverse events reported for LATUDA compared to placebo were nausea (16% vs. 5.8%), somnolence (9.1% vs. 4.7%), weight gain (6.9% vs. 1.7%), vomiting (6.3% vs. 3.5%), dizziness (5.7% vs. 4.7%) and insomnia (5.1% vs. 2.3%). LATUDA was associated with no increases in fasting glucose or lipids, and minimal increase in mean weight vs. placebo (+0.74 kg vs. +0.44 kg). (more…)

MedicalResearch.com Interview with: Professor Hermundur Sigmundsson Department of Psychology Norwegian University of Science and Technology MedicalResearch.com: What is the background for this study? What are the main findings? Response: There are around 23 baby-swimming instructors in Iceland who are offering baby swimming-courses. However, Snorris way to do this is unice after my knowledge. He has been doing baby swimming from 1990 - and has had around 7.000.- babies He heard about this from Norway and discovered that very young babies can stand in this way. He discovered this through practical experience. It works like this:  When holding children in the water - He put his hand under the feet of the children - and lift little bit under i.e gives some pressure (tactile stimuli) the children are gradually able to stand in the feet - so stimuli and experience is important. When they are able to stand once they are able to stand again. How long time it takes for each baby to be able to stand varies a lot - as in our study - the youngest was 3.6 months old. One of the participants was standing in 15 sec in the hands of Snorri in the first week of baby swimming course. I did see babies stand first soon after Snorri started baby swimming instruction around 1990-1991. I was very surprised - and was thinking how is it possible? This is not supported by the literature. My colleagues an I thought about this as a window to study development of balance and coordination in infants. The issue about reflexes versus voluntary movement through experience was central.

MedicalResearch.com Interview with: Dr Annie Herbert, PhD Department of Behavioural Science and Health, Institute of Epidemiology and Healthcare University College London London  UK  MedicalResearch.com: What is the background for this study? Response: 1 in 25 adolescents (i.e. one in every classroom) will be admitted to hospital as an emergency with injuries related self-harm, drug or alcohol misuse, or violence. Currently, the guidelines for how these adolescents are managed differ greatly depending on the type of injury they come in with (whether through self-harm, drug or alcohol misuse, or violence). MedicalResearch.com: What are the main findings? Response: In our study, we found that adolescents admitted with any of these injuries were at an increased risk of suicide and of drug or alcohol related death in the ten years after leaving hospital, compared to other admitted adolescents.While the overall risk is relatively low—for example, 2–3 girls out of 1000 and 7 boys out of 1000 who are admitted as an emergency to hospital with drug or alcohol related injuries die from suicide within 10 years—the rates are 5–6 times higher than among adolescents admitted to hospital following an accident.
