Prof. Denise Kendrick Professor of Primary Care Research Division of Primary Care, University Park Nottingham UKMedicalResearch.com Interview with: Prof. Denise Kendrick Professor of Primary Care Research Division of Primary Care, University Park Nottingham UK Medical Research: What is the background for this study? What are the main findings? Prof. Kendrick: More than 1 million US children aged 0-4 years attend emergency departments because of  a fall each year. Approximately half of all ED attendances in this age group are for falls, and most of these are falls from furniture, most commonly from beds, chairs , baby walkers, bouncers, changing tables and high chairs. In the US around 18,000 0-4 year olds are admitted to hospital following a fall each year  and in 2012 there were 31 deaths in the US in 0-4 year olds from falls. Healthcare costs for falls in the US  were estimated at $439 million for hospitalised children and $643 million for  ED attendances in 2005. We found that children were more likely to attend hospital because of a fall from furniture in families that did not use safety gates across doorways or on stairs. For infants (aged 0-12 months) we found they were more likely to attend hospital because of a fall from furniture if they had been left on a raised surface (e.g. beds, sofas, work tops etc), had diapers changed on a raised surface or been put in a car seat or bouncing cradle on a raised surface. We also found that children aged over 3 years who had climbed or played on furniture were more likely to have a fall requiring a hospital visit than children who had not. Finally we found that children whose parents had not taught their children rules about climbing on objects in the kitchen were more likely to have a fall needing a hospital visit than children whose parents had taught these rules.

MedicalResearch.com Interview with: Regina Marie Sullivan PhD Professor Child and Adolescent Psychiatry Nathan Kline Institute The Child Study Center at NYU Langone Medical Center Department of Child and Adolescent Psychiatry One Park Ave 8th Floor, New York, NY 10016 Medical Research: What is the background for this study?  Dr. Sullivan: Managing pain during medical procedures in a critically important issue in medicine today. Our study was designed to better understand one method of reducing pain in young infants - having the caregiver be in contact with the baby during the painful procedure, which reduces the infant's behavioral response to the medical procedure. This study explored the neural basis of the ability of the caregiver to reduce the pain response. (more…)

MedicalResearch.com Interview with: Dr. Wanjun Cui, MS PhD Department of Health and Human Services, Centers for Disease Control and Prevention (CDC) Medical Research: What is the background for this study? What are the main findings? Authors’ response: Asthma is a leading chronic disease among adolescents that adversely affects their health. However, it is unclear how asthma influences their perceived health or health-related quality of life (HRQOL). Because their perceptions of their health may differ from those of their caregivers (such as parents or health professionals), knowing how adolescents with asthma would rate their own health is very important. Our study compares the responses of adolescents with and without asthma about different aspects of HRQOL including their overall health, their recent physical health, their recent mental health, and their recent activity limitations due to health. Unlike previous U.S. studies based on small clinical samples, our study used a nationally representative sample of U.S. adolescents that can be generalized to the whole U.S. adolescent population. We found that asthma is adversely associated with almost all these aspects of HRQOL but only among those with asthma and current symptoms such as wheezing and dry cough. Adolescents with asthma without current symptoms did not report significantly worse HRQOL than those without asthma. For example, compared with those who never had asthma, adolescents with asthma and symptoms of dry cough or wheezing reported significantly more fair or poor self-rated health (14% vs. 8%), 34% more recent physically unhealthy days , and 26% more recent mentally unhealthy days. More importantly, adolescents with asthma who currently smoked cigarettes or reported limited physical functioning reported even worse physical and mental HRQOL. (more…)

MedicalResearch.com Interview with: Maria Pesonen MD, PhD Specialist in Dermatology Assistant Chief Medical Officer Finnish Institute of Occupational Health Occupational Medicine Helsinki, Finland Medical Research: What is the background for this study? What are the main findings? Dr. Pesonen: Skin prick test is a widely used, established methods in assessing immediate (i.e. immunoglobulin E-mediated) sensitization. However, the knowledge on long-term reproducibility and predictive value of skin prick testing in children has been limited. We assessed the predictive value of skin prick testing in the setting of a follow-up study on healthy, unselected newborns, who were followed up to age 20 years with skin prick testing with 11 common allergens, structured interview and clinical examination at ages 5, 11 and 20 years. The reproducibility of skin prick test positivity at age 5 years was 100% at ages 11 and 20 years, i.e. none of the skin prick positive subjects turned negative during the follow-up. Gaining of new sensitizations to aeroallergens was common. Skin prick test positivity at age 5 years predicted allergic symptoms at ages 11 (sensitivity 28%, specificity 94%) and 20 years (sensitivity 23%, specificity 91%), but not atopic dermatitis. (more…)

What are the main findings? Dr. Lodha: Apneic episodes (cessation of breathing) occur in the premature infants. Caffeine is the most commonly used medication for apnea of prematurity. Normally caffeine started on day 3 of life for apnea. However, there is no strong evidence that starting caffeine on day 1 or 2 life has some extra advantages in premature infants. Our study has a large number of premature infants. Our study determined the association of early initiation of caffeine therapy in very preterm neonates and neonatal outcomes. The main finding of our study was that early use of caffeine was associated with a reduction in the rate of death or bronchopulmonary dysplasia and patent ductus arteriosus. We did not find any adverse impact on any other outcomes. (more…)

MedicalResearch.com Interview with: Ian R. Macumber MD Pediatric Nephrology, Seattle Children's Hospital Seattle, Washington Medical Research: What are the main findings of the study? Dr. Macumber: The main finding is that there is a strong association between maternal obesity and odds of congenital anomalies of the kidney and urinary tract (CAKUT) in offspring.  This relationship remains strong when looking at offspring with renal malformation (excluding non-renal congenital anomalies of the kidney and urinary tract), or in offspring with isolated congenital anomalies of the kidney and urinary tract (no congenital anomalies elsewhere in the body).  There is a dose-response relationship to this association, with the offspring of extremely obese mothers have even higher odds of having congenital anomalies of the kidney and urinary tract.

Elyse O. Kharbanda MD MPH HealthPartners Medical and Dental GroupMedicalResearch.com Interview Elyse O. Kharbanda MD MPH HealthPartners Medical and Dental Group Medical Research: What is the background for this study? What are the main findings? Dr. Kharbanda: In 2010, due to a pertussis outbreak and neonatal deaths, the California Department of Public Health recommended that the Tdap vaccine be administered during pregnancy.  Tdap is now recommended by the Advisory Committee on Immunization Practices (ACIP) for all pregnant women during each pregnancy.  We wanted to assess the impact of this recommendation. The main findings were that Tdap vaccination during pregnancy was not associated with increased risk for hypertensive disorders of pregnancy, preterm birth, or having a baby who is small for his or her gestational age. The study found a small increased risk for being diagnosed with chorioamnionitis, an inflammation of the fetal membranes caused by bacterial infection.  These findings should be interpreted with caution as the magnitude of the risk was small.  In addition, there was no associated risk for preterm birth, which often occurs as a result of chorioamnionitis.  Furthermore, among the subset of women with a chorioamnionitis diagnosis whose charts were reviewed, many did not have a clinical picture that was clearly consistent with chorioamnionitis.

Marcel J Casavant MD FACEP FACMT Chief of Toxicology, Nationwide Children's Hospita Medical Director, Central Ohio Poison Center Clinical Professor, The Ohio State University Colleges of Medicine & Pharmacy Columbus OH USA 43205-2696MedicalResearch.com Interview with: Marcel J Casavant MD FACEP FACMT Chief of Toxicology, Nationwide Children's Hospita Medical Director, Central Ohio Poison Center Clinical Professor, The Ohio State University Colleges of Medicine & Pharmacy Columbus OH USA 43205-2696 Medical Research: What is the background for this study? What are the main findings?  Dr. Casavant: Laundry detergent pods reached the US market shelves in early 2012; almost immediately parents started calling poison control centers about their children’s exposures to these products. Since then the CDC, the CPSC, the American Association of Poison Centers, and others have issued warnings about these products. Several papers and numerous abstracts have described injuries to various groups of children; we therefore chose to analyze and describe what happened to all US children with exposure to one of these products reported to a poison control center in 2012 and 2013. The main finding: these products are dangerous to children! Over those two years we found more than 17,000 young children exposed to pods, more than 6,000 seen in an emergency department, more than 700 admitted to a hospital, and among these, more than half required intensive care. Two young children died, both in 2013. Our study was published online on November 10, 2014 (http://www.aap.org/en-us/about-the-aap/aap-press-room/Pages/Laundry-Detergent-Pods-Can-Be-a-Serious-Poisoning-Risk-in-Children.aspx) and will appear in the December 2014 print edition of Pediatrics (volume 134 number 6).

What are the main findings? Dr. Griffin: In Tennessee, the introduction in 2010 of a new pneumococcal vaccine for infants and young children was associated with a 27 percent decline in pneumonia hospital admissions across the state among children under age 2. The recent decline in Tennessee comes on top of an earlier 43 percent decline across the United States associated with the introduction in 2000 of the first pneumococcal vaccine for children under 2 years of age.

What are the main findings? Prof. Cicuttin: Previous research found that low birth weight and preterm birth have been linked to hypertension, cardiovascular disease, insulin resistance and reduced bone mass in adulthood.  Given these adverse outcomes related to birth weight and preterm birth we set out to investigate if low birth weight and preterm birth also played a role in increase risk of joint replacement surgery as adults. We found that  low birth weight and preterm birth were associated with a 2-fold increased risk of hip but not knee replacement surgery. (more…)

MedicalResearch.com Interview with: Anne Tharner, PhD and Jessica C. Kiefte-de Jong, PhD Department of Epidemiology Erasmus Medical Center, Rotterdam The Netherlands Medical Research: What is the background for this study? What are the main findings? Response: Constipation is one of the most common health problems in children, and occurs in most cases without organic reason. In our study, we examined if fussy eating behavior might be related to constipation in children. “Fussy eaters” are children who reject specific foods – often (green and bitter) vegetables – and often compensate this with the intake of less healthy but highly palatable foods (such as fast food or sweets). This kind of diet might be one of the reasons for constipation in children, but at the same time, children might develop difficult eating patterns due to digestive problems such as constipation. Therefore, we examined whether fussy eating and functional constipation mutually affect each other, which might point to the development of a vicious cycle. We examined this in a large study including almost 5000 children aged 2-6 years who participated in a longitudinal study in Rotterdam, the Netherlands. Families were regularly followed up starting in pregnancy. Our main finding was that fussy eating co-exists with functional constipation and also predicts subsequent development of functional constipation. In addition, we also found evidence for the reverse, as functional constipation predicted subsequent fussy eating behavior. Together with previous studies, our findings suggest that indeed a vicious cycle may develop throughout childhood in which children’s constipation problems and problematic eating behavior mutually affect each other. On the one hand, fussy eating might affect the development of functional constipation via poor dietary quality which is a characteristic for the diet of fussy eaters. On the other hand, our findings show that functional constipation in also predicts future fussy eating. This pathway is less well studied, but it is conceivable that children with constipation and the accompanying abdominal pain and painful defecation may develop problematic eating behavior. (more…)

Response: The Healthy Eating, Aerobic and Resistance Training in Youth study examined the effects of exercise on body composition and cardiometabolic risk markers in adolescents with obesity. A total of 304 overweight or obese adolescents were randomized to four groups. The first group performed resistance training involving weight machines and some free weights; the second performed only aerobic exercise on treadmills, elliptical machines and stationary bikes; the third underwent combined aerobic and resistance training; and the last group did no exercise training. All four groups received nutritional counseling. In analyses involving all participants regardless of adherence, each exercise program reduced percent body fat, waist circumference and body mass index to a similar extent, while the diet-only control group had no changes in these variables. In participants who exercised at least 2.8 times per week, we found that combined aerobic and resistance training produced greater decreases in percentage body fat, waist circumference, and body mass index than aerobic training alone. Waist circumference decreased close to seven centimeters in adherent participants randomized to combined aerobic plus resistance exercise, versus about four centimeters in those randomized to do just one type of exercise, with no change in those randomized to diet alone.

Response: The study found that about 25% of infants consistently deviated from the routine vaccine schedule recommended by the American Academy of Pediatrics (AAP).  Alterations included either consistently refusing a recommended vaccine or reducing the number of vaccines given at each visit. These deviations are generally associated with intent to use an alternative vaccination schedule. Infants who did not follow the AAP recommended schedule were more likely to be unprotected against vaccine preventable diseases for a longer period of time. Only 1 in10 infants vaccinated on an alternative schedule were up-to-date at 9 months of age. (more…)

Georg Loss, PhD Dr. von Hauner Children’s Hospital Ludwig Maximilians University of Munich Munich, GermanyMedicalResearch.com Interview with: Georg Loss, PhD Dr. von Hauner Children’s Hospital Ludwig Maximilians University of Munich Munich, Germany Medical Research: What are the main findings of the study? Dr. Loss: In this large population based cohort study we observed that consumption of fresh unprocessed cow’s milk protected from respiratory infections, febrile illness and inflammation of the middle ear during the first year of life. The risk of developing these conditions was reduced by up to 30%, and the effect was diminished if the milk was heated at home before consumption. Conventionally pasteurized milk retained the ability to reduce the risk of febrile illness, while exposure to the higher temperatures used in UHT (Ultra-heat-treatment) processing eliminated the effect altogether. Importantly, the positive impact of fresh milk could be clearly separated from the confounding effects of other elements of the children’s nutrition. Furthermore, infants fed on unprocessed milk were found to have lower levels of the C-reactive protein, which is a measure of inflammation status. (more…)

Response: From 2002-2012, a child younger than 6 years old experienced an out-of-hospital medication error every 8 minutes. That’s a total of 696,937 during the study period, or 63,358 per year. Almost all happened at the child’s residence. The rate and number of errors decreased with increasing age. Analgesics were the mostly commonly involved medications (25.2%), followed by cough and cold medications (24.6%). More than 1 in 4 (27%) of the errors happened when a child inadvertently took or was given medication twice. Errors also happened when children took or were given an incorrect dose, when medication measurements were confused, and when the wrong medication was taken or given. (more…)

Temple, PhD Associate Professor and Psychologist Director, Behavioral Health and Research Department of Ob/Gyn UTMB Health Galveston, TX 77555-0587 Medical Research: What are the main findings of the study? Dr. Temple: Through previous research, we know that teen sexting is related to actual sexual behaviors, but we did not have any information on the temporal link between these two behaviors. In short, we found that teens who sexted had 32% higher odds of being sexually active over the next year relative to youth who did not sext – this was even after controlling for history of prior sexual behavior, ethnicity, gender, and age. We also found that active sexting (actually sending a naked picture to another teen) mediated the relationship between passive sexting (asking for or being asked for a sext) and sexual behaviors. In other words, while sending a sext was predictive of subsequent sexual behavior, asking for/being asked for a sext was only associated with sexual behavior through its relationship with active sexting.

MedicalResearch.com Interview, Sara Sammallahti, MA Institute of Behavioral Sciences University of Helsinki, Finland.   Medical Research: What are the main findings of the study? Answer: Not only did we find that faster growth right after preterm birth is associated with better neurocognitive abilities - we also showed that these effects persist into adulthood, that they are seen across a wide spectrum of abilities, and that head growth very early on seems especially relevant in predicting long-term outcomes. These associations were found when we examined 103 young adults who were born prematurely and with very low birth weight (under 1500 grams). (more…)

Dr. Lorraine Yeung Division of Birth Defects and Developmental Disabilities National Center on Birth Defects and Developmental Disabilities, CDCMedicalResearch.com Interview with: Dr. Lorraine Yeung Division of Birth Defects and Developmental Disabilities National Center on Birth Defects and Developmental Disabilities, CDC Medical Research: What are the main findings of the study? Dr. Yeung: In this report, we looked at the percentages of children who received various recommended clinical preventive services. We found that millions of infants, children, and adolescents in the U.S. did not receive key clinical preventive services. This report provides a baseline snapshot of the use of 11 key clinical preventive services before or shortly after the Affordable Care Act went into effect. A focus of the Affordable Care Act is on improving prevention of illness and disability and it does so by requiring new health insurance plans to provide certain clinical preventive services at no additional cost — with no copays or deductibles. This is important because we know increasing the use of these services can improve children’s health and promote healthy lifestyles that will enable them to reach their full potential. Some of the important findings in this report were:          In 2007, parents of almost eight in 10 (79 percent) children aged 10-47 months reported that they were not asked by healthcare providers to complete a formal screen for developmental delays in the past year.          In 2009, more than half (56 percent) of children and adolescents did not visit the dentist in the past year and nearly nine of 10 (86 percent) children and adolescents did not receive a dental sealant or a topical fluoride application in the past year.          Nearly half (47 percent) of females aged 13-17 years had not received their recommended first dose of HPV vaccine in 2011.          Approximately one in three (31 percent) outpatient clinic visits made by 11-21 year-olds during 2004–2010 had no documentation of tobacco use status; eight of 10 (80 percent) of those who screened positive for tobacco use did not receive any cessation assistance.          Approximately one in four (24 percent) outpatient clinic visits for preventive care made by 3-17 year olds during 2009-2010 had no documentation of blood pressure measurement.

Dr. Doyle: From collectively pooling data from five large trials carried out around the world over the past 20 years, we know that magnesium sulfate given under strict medical protocols in hospital to women threatening to deliver preterm reduces the risk of cerebral  palsy in their children in early childhood.  Following  from this knowledge, magnesium sulfate is now given routinely to women, under strict medical conditions, who are threatening to deliver very early in Australia, and in other parts of the world, to try to prevent cerebral palsy in their child.  What we do not know is if magnesium sulfate used this way has any longer-term effects on the brain or on other important outcomes. One of the initial studies that contributed to the overall evidence about cerebral palsy was carried out in Australia and New Zealand and completed more than 10 years ago.  Over 1000 women and their babies were enrolled in that study and although the rate of cerebral palsy was not substantially reduced by magnesium sulfate in our study, we showed that there were fewer children at 2 years of age who were not walking in the group whose mothers were given magnesium compared with those whose mothers were given placebo.  With this knowledge, and given the unknown longer-term benefits or risks, we re-evaluated the children from our study at school-age, between 6-11 years of age.  We thoroughly evaluated their brain function, including movement and co-ordination, thinking ability, behaviour, and school progress, as well as general health and well-being.  The basic message from our longer-term study is that magnesium sulfate, as used in our trial, does not have any substantial benefits or harms on brain or cognitive function, or any other outcome at school age.

Dr. Li: Using the 2001 to 2009 National Program of Cancer Registries (NPCR) and Surveillance, Epidemiology, and End Results (SEER) data, which represent 94.2% of the US population, we identified 120,137 pediatric cancer cases with an incidence rate of 171 cases per million children and adolescents. Overall cancer incidence rates were stable from 2001-2009. However, we found rates were increasing significantly at 1.3% per year in African American children and adolescents.  This increase might be partially attributed to the rise among renal tumors and thyroid cancer. We also found rising incidence in thyroid cancer and renal carcinoma among children and adolescents. As has been previously established, pediatric cancer is more common in males, in white, in adolescents, and in the Northeast. Leukemia is the most common pediatric cancer, followed by central nervous system (CNS) neoplasms, and then lymphomas. (more…)

Dr. Steve Turner Child Health, Royal Aberdeen Children's Hospital Aberdeen,UKMedicalResearch.com: Interview with: Dr. Steve Turner Child Health, Royal Aberdeen Children's Hospital Aberdeen,UK   Medical Research: What are the main findings of the study? Dr. Turner: There is evidence that being small for a given gestational age is associated with a broad range of what could be loosely considered “disadvantageous” outcomes in early childhood, eg increased risk for wheeze, increased blood fat levels, increased blood pressure and low bone mineral density.  Many of these outcomes are subclinical – ie unless they were measured no-one would be any the wiser – and what remains to be determined is whether as these individuals grow up these subclinical measurements become important.  Follow up may take many years, decades for outcomes such as coronary artery disease and type II diabetes.

Medical Research: What are the main findings of the study? Dr. Nylund: The main findings of our study were that among children who were identified as having a diagnosis of Clostridium difficile infection (CDI), CDI was about twice as likely to occur during periods when the child was taking either a proton pump inhibitor or histamine-2 receptor antagonist. In brief, we performed a type of observational study called a self-controlled case series. Our data source was the military health system database which contains billing records for patients seen in military and civilian facilities. We identified all cases of Clostridium difficile infections in children ages 2-18 over the period of October 2001 to July 2013. We also identified periods when children were prescribed both proton pump inhibitors and histamine-2 receptor antagonists over the same time period. We compared the incidence of CDI during periods prescribed acid suppression medications to periods not prescribed these medications. (more…)

Dr. MacDonald: We found that vitamin K was refused by only a very small number of parents in our study population (0.3%) but that the number appears to be increasing (almost doubling in the past 7 years). The parents that refused vitamin K for their child were more likely to be those that delivered at home and/or with a midwife. We also found that parents who refused vitamin K for their child were also much more likely to go on to refuse all vaccinations by 15 months of age. (more…)
