Terisa P. Gabrielsen, PhD, NCSP Assistant Professor, School Psychology Dept. of Counseling Psychology and Special Education Brigham Young University, Provo, UT 84602MedicalResearch.com Interview with: Terisa P. Gabrielsen, PhD, NCSP Assistant Professor, School Psychology Dept. of Counseling Psychology and Special Education Brigham Young University, Provo, UT 84602 Medical Research: What is the background for this study? What are the main findings? Dr. Gabrielsen: One of the keys to improving outcomes for individuals with outcomes is to begin intervention as early as possible, which means we need to identify autism symptoms as early as possible, preferably during the early toddler years.  The current study grew out of a screening feasibility study to see what would happen if pediatricians followed the AAP guidelines for screening every child for autism at ages 18 and 24 months as part of their regular pediatric care appointments.  That study  was conducted in a large, independent community pediatrics practice.  We found that universal screening of 796 patients helped to identify 10 toddlers with autism who had not previously been referred for evaluations.  Physicians had previously identified 3 others with autism in the group, and toddlers with other delays, such as language delays, were also identified through the screening process.  We wondered what some possible causes were for the low rate of autism referrals and designed the current study to look for what information was available to a pediatrician during the timespan of a typical pediatric exam.  We found that even in toddlers with autism, a brief (10-minute) sample contains an overwhelming ratio of typical behaviors (averaging 89%) compared to infrequent atypical behaviors (11%)  that would indicate the presence of autism.  We had autism experts identifying the behaviors from videos of the evaluations of children in the previous study, so they had many luxuries that a clinician doesn't have during an exam (i.e., ability to focus on one aspect of development, ability to rewind and re-view behaviors).  After watching the 10-minute video observations, we asked our experts, "Would you refer this child for an autism evaluation?"  We found that even the experts missed referring a child for an autism evaluation 39% of the time when the only data available were the brief observations.

MedicalResearch.com Interview with: Tomi  Ajetunmobi MSc and Bruce Whyte MSc Bespoke Specialist Services Information Services Division NHS National Services Scotland Edinburgh Medical Research: What is the background for this study? What are the main findings? Response: In developing countries, breast milk is considered the best source of nutrition for human infants, vital for child health and development. In developed counties, however, the message that ‘breast is best’ though widely accepted, is not practiced, particularly in the UK; debate continues on the role played by infant feeding in ensuring child health. The benefits of breastfeeding in terms of child health have been difficult to prove methodologically for ethical reasons. Moreover, most studies that have shown an association are often limited by the sample size, scope of the data and adjustment for a wide range of confounders particularly socioeconomic factors, which influence both infant feeding and child health outcomes. Using a range of linked administrative records comprising 502,948 singletons born in Scotland between 1997 and 2013 (representing approximately 70% of all Scottish births) , the study aimed to quantify the association between infant feeding patterns reported at a routine check-up 6 to 8 weeks after birth and hospital admission for childhood common illnesses. These included gastrointestinal, respiratory and urinary tract infections, otitis media, fever, asthma, eczema, diabetes and dental caries. The linkage made it possible to adjust for a wide range of confounders. Our findings were consistent with other studies and showed a greater risk of hospital admission amongst infants who were not breastfed particularly within six months of birth, even after adjustment for parental, delivery and infant health factors and features of the health care system. At least one in five hospitalisations for gastrointestinal and lower respiratory tract infections within six months of birth may have been averted (all other factors remaining constant) had all children in the cohort been exclusively breastfed 6 to 8 weeks after birth. The association was also evident beyond six months of birth. (more…)

Prof. H. Szajewska The Medical University of Warsaw Department of Paediatrics Warsaw, PolandMedicalResearch.com Interview with: Prof. H. Szajewska The Medical University of Warsaw Department of Paediatrics Warsaw, Poland   Medical Research: What is the background for this study? Dr. Szajewska: Proton pump inhibitors (PPIs) are increasingly being used in the management of irritability and excessive crying in young infants. For example, a 7-fold increase in PPI prescriptions for infants was demonstrated in one US-based study. While differences among countries may occur, over-prescription of PPIs for infants remains a problem. The use of PPIs is mainly based on the assumption that these symptoms are attributable to gastroesophageal reflux or gastroesophageal reflux disease. Indeed, in infants, common symptoms of both conditions include regurgitation or vomiting associated with irritability or crying. However, there is still uncertainty with regard to the role of proton pump inhibitors for the management of excessive crying and irritability. Dr. Szajewska: What are the main findings? We aimed to examine whether proton pump inhibitors are effective in the management of excessive crying and irritability in infants. Only 5 randomized controlled trials fulfilled the inclusion criteria, so the evidence remains limited. There was variability in how crying/irritability outcomes were reported, but all trials used reliable methods. Some trials showed a decrease in crying/irritability from baseline to the end of the intervention; a similar effect was observed in the control group. However, no significant differences between the treatment groups were observed. (more…)

Yvonne Wu MD Professor of Clinical Neurology and Pediatrics UCSF School of MedicineMedicalResearch.com Interview with: Yvonne Wu MD Professor of Clinical Neurology and Pediatrics UCSF School of Medicine   Medical Research: What is the background for this study? What are the main findings? Dr. Wu: Newborn infants commonly have elevated bilirubin levels, manifested as jaundice, because the body's mechanisms for breaking down bilirubin have not yet fully matured.  Although high bilirubin levels are almost always well tolerated, extremely high bilirubin levels may lead to brain injury, or kernicterus, which in turn can cause a very severe form of cerebral palsy.  When bilirubin levels are extremely high, or when bilirubin levels remain high despite phototherapy, it is recommended that an exchange transfusion be performed to prevent brain injury and cerebral palsy.  The American Academy of Pediatrics (AAP) has published recommendations on when an exchange transfusion should be performed, based on bilirubin level, age of infant and other clinical factors.  However, no previous study had examined the actual risk of cerebral palsy in infants whose bilirubin levels exceeded the exchange transfusion thresholds. Among 500,000 newborns born at Kaiser Permanente Northern California over a 17-year period, we found 1833 who had at least one bilirubin level above the AAP exchange transfusion level.  There were only 3 cases of cerebral palsy due to kernicterus in this group, even though only 42 (2.3%) of them had received exchange transfusions.  All 3 infants had bilirubin levels at least 5 mg/dL above the AAP exchange transfusion threshold and all 3 infants had 2 or more other risk factors for brain damage, including prematurity, sepsis, hypoxia and the hereditary blood disorder G6PD deficiency.  We did not identify any cases of kernicterus among otherwise well term babies, even at bilirubin levels that exceeded the AAP exchange transfusion threshold.

MedicalResearch.com Interview with: Professor of Pediatrics Hans Bisgaard, MD, DMSc Copenhagen Prospective Studies on Asthma in Childhood Herlev and Gentofte Hospital, University of Copenhagen, Denmark Medical Research: What is the background for this study? What are the main findings? Prof. Bisgaard: The purpose of this study was to look for a shared risk factor for immunological diseases which make its debut in childhood. During the recent decades a parallel increase in prevalence of immune diseases such as asthma, allergy, inflammatory bowel disease, and type 1 diabetes have been observed in westernized countries. The rate of cesarean delivery has increased in the same period and has previously been associated with the development of some of these diseases. This study takes advantage of the unique and valuable nationwide registry data in Denmark to establish a large population based cohort (2 million term children) with 35 years of follow up (in the period 1977-2012). We found cesarean delivery to be a common risk factor for a range of childhood immunological diseases: asthma, juvenile arthritis, inflammatory bowel diseases, connective tissue disorders, immune deficiencies and leukemia, but with no association to psoriasis, celiac disease, and diabetes type 1.

Jonathan Olsen Institute of Primary Care and Public Health Cardiff University Heath Park CardiffMedicalResearch.com Interview with: Jonathan Olsen Institute of Primary Care and Public Health Cardiff University Heath Park Cardiff MedicalResearch: What is the background for this study? What are the main findings? Response: Molluscum Contagiosum is a common skin condition in children which has a prevalence of between 5.1% to 8% in children aged 14 years and under. Strikingly however, there is little epidemiological evidence describing the natural history, transmission between family members and impact upon quality of life of molluscum contagiosum. Our research aimed to address this gap in evidence by conducting a prospective cohort study of UK children recruited by clinical and self-referral using the validated Molluscum Contagiosum Diagnostic Tool for Parents (MCDTP). We recruited 306 children during 2013 and showed that on average lesions will last for 12 months, however 30% still had lesions at 18 months and 13% still had lesions at 24 months. Most children experienced only a small effect on their quality of life from the condition, however 1 in 10 experienced a large or very large impact on their quality of life. The condition was shown to be highly contagious with further transmission between children living in the same household as an index case shown in 40%. (more…)

Miranda van Tilburg, PhD Associate Professor of Medicine University of North CarolinaMedicalResearch.com Interview with: Miranda van Tilburg, PhD Associate Professor of Medicine University of North Carolina Medical Research: What is the background for this study? What are the main findings? Dr. van Tilburg: Functional gastrointestinal disorders are common in children, adolescents and adults but little is known about the prevalence in infants and toddlers.  Functional gastrointestinal disorders in infancy include disorders such as regurgitation, colic, and dyschezia, while functional gastrointestinal disorders in toddlers include functional constipation, functional diarrhea, functional dyspepsia, cyclic vomiting, and rumination. Of these disorders only colic and regurgitation have received much research attention. Prevalence, cause and consequences of most functional gastrointestinal disorders in infants and toddlers are largely unknown. We set out to determine the prevalence in the US by asking a representative sample of mothers to report on their child’s symptoms. Our study found that 27% of infants and toddlers may suffer from a functional gastrointestinal disorder. Among infants, regurgitation was the most common disorder and among toddlers constipation. Despite functional gastrointestinal disorders generally being more prevalent in older girls and adult women, no sex differences were found in this age group. Toddlers who suffer from a functional gastrointestinal disorders had lower quality of life and made more health care visits. (more…)

MedicalResearch.com Interview with: Joseph A Simonetti, MD MPH Research Fellow Harborview Injury Prevention & Research Center University of Washington Seattle, WA, USA Medical Research: What is the background for this study? What are the main findings? Dr. Simonetti: Studies have consistently shown that children living in households where firearms are stored safely have a lower risk of suffering firearm injuries, including lethal firearm injuries, compared to those living in households where firearms are stored unlocked and/or loaded. Safe firearm storage is widely recommended by public health experts, professional medical societies, and gun rights organizations, especially for households where children might be suffering from mental heath and substance abuse issues that put them at increased risk for suicide or unintentional injury. Our goal was to find out if those recommendations were being effectively implemented in the community. To do this, we used survey data that assessed mental health conditions and firearm access among a nationally representative sample of US adolescents. Medical Research: What are the main findings? Dr. Simonetti: First, we confirmed previous findings that a large proportion of US adolescents have access to a firearm in the home. Of those who reported living in a home with a firearm, 40% said they could immediately access and shoot the firearm. Second, the prevalence of most mental health diagnoses was similar between adolescents who did and did not report firearm access. However, a greater proportion of adolescents with firearm access had drug and alcohol disorders compared to adolescents who reported living in a home with a firearm but did not have access to the firearm. The main finding was that children with mental health risk factors for suicide were just as likely to report in-home firearm access as those without identified risk factors. This finding held true even when comparing firearm access between children with no identified risk factors and those who reported a recent suicide attempt, who arguably have the highest suicide risk in this sample.

What are the main findings? Response:  Influenza can be a very serious disease and is more than just a bad cold.  Some children who are 6 months through 8 years need two doses of the influenza vaccine in a season depending on if and when they received previous influenza vaccine doses. We know that only about half of these families who want to vaccinate their children against the flu and get the first dose, come back to get the second dose. (more…)

Seetha Shankaran MD Director, Neonatal-Perinatal Medicne Children's Hospital of Michigan and Hutzel Women's Hospital Detroit, MIMedicalResearch.com Interview with: Seetha Shankaran MD Director, Neonatal-Perinatal Medicne Children's Hospital of Michigan and Hutzel Women's Hospital Detroit, MI Medical Research: What is the background for this study? What are the main findings? Dr. Shankaran: The background for this study is that term newborn infants born following lack of blood flow and oxygen to the brain are at high risk for death or disability, including motor and developmental handicaps. Hypothermia (lowering the core body temperature to 33-34°C for 72 hours has been shown to decrease the rate of death or disability to 44 to 55%. Hypothermia is currently the only proven therapy to reduce these devastating outcomes. The hypothermia therapy provided to term newborns was based on laboratory experiments that demonstrated that in animal models subjected to hypoxia and ischemia, cooling reduced brain injury. In the NICHD Neonatal Research Network (a group of academic centers across the US), in 2005 we reported the first trial of whole-body cooling to 33.5°C for 72 hours and noted a reduction in death or disability in infancy.  When the infants in the study where followed to childhood, we noted that this reduction in death or disability continued to childhood. Recent laboratory experiments have demonstrated that brain injury continues for days or weeks after the hypoxic-ischemic injury. Other laboratory experiments noted that cooling for a greater depth than 33-34°C (as long as the temperature does not decrease much lower) can reduce brain injury further. Based on this information, in the NICHD Neonatal Research Network we designed a study, among term infants with moderate or severe encephalopathy to compare longer cooling and deeper cooling to see if death or disability can be reduced. Term infants with moderate or severe encephalopathy were randomly assigned at <6 hours of age to 4 groups of therapy; 33.5°C for 72 hours, 32.0°C for 72 hours, 33.5°C for 120 hours and 32.0°C for 120 hours. The  goal was to compare death or disability rates between the 2 durations of cooling (72 hours vs. 120 hours) and 2 depths of cooling (33.5 C vs. 32.0°C) and was designed to recruit 726 infants. A independent data safety and monitoring committee was appointed by the director of NICHD to monitor safety events after the first 50 infants were enrolled and then following the enrollment of every 25 infants. The safety events monitored included mortality in the neonatal intensive care unit (NICU), cardiac arrhythmia, persistent acidosis and major vessel bleeding or thrombosis. The study was started in October 2010. Medical Research: What is the background for this study? What are the main findings? Dr. Shankaran: In November 2013 the study was closed by the data safety and monitoring committee after 8 reviews of study data, following recruitment of 364 neonates because of emerging safety concerns as well as futility analyses. The NICU death rates were 7% (7 of 95) for the 33.5°C for 72 hour group, 14% (13 of 90) for the 32.0°C for 72hr group, 16% (15 of 96) in the 33.5°C for 120 hour group and 17% for the 32.0°C for 120 hour group. The adjusted risk ratio (95% CI) for death for the 120 hour vs. the 72 hour was not significantly different 1.37 (0.92-2.04) nor was it significantly different for the 32.0°C group compared to the 33.5°C group 1.24 (0.69-2.25).  The safety outcomes were similar between the 120 vs. 72 hour groups and the 32.0°C vs. the 33.5°C groups, except that major bleeding occurred among 1% in the 120 group vs. 3% in the 72 hours group, RR 0.25 (0.07-0.91). Futility analyses noted that the probability of detecting benefit of longer cooling, deeper cooling or both for death in the NICU was <2%. The follow -up of infants enrolled into the study for 18 months is on-going. (more…)

Ron B. Mitchell, MD Professor of Otolaryngology and Pediatrics William Beckner Distinguished Chair in Otolaryngology Chief of Pediatric Otolaryngology UT Southwestern and Children's Medical Center Dallas ENT Clinic Dallas, TX 75207MedicalResearch.com Interview with: Ron B. Mitchell, MD Professor of Otolaryngology and Pediatrics William Beckner Distinguished Chair in Otolaryngology Chief of Pediatric Otolaryngology UT Southwestern and Children's Medical Center Dallas ENT Clinic Dallas, TX 75207 Medical Research: What is the background for this study? What are the main findings? Dr. Mitchell: The “gold standard” for the diagnosis of and quantification of obstructive sleep apnea (OSA) is polysomnography (PSG or a ‘sleep study’). However, the majorities of T&A procedures are done without PSG and are based on a clinical diagnosis. This is because PSG is expensive, requires overnight observation and is often unavailable. It is important to diagnose and quantify OSA as it allows for surgical planning and predicts the need and type of treatment after surgery. We used data from the Childhood Adenotonsillectomy (CHAT) study; a large multicenter trial (RCT), to look at the ability of clinical parameters to predict the severity of obstructive sleep apnea in children scheduled for a T&A. The main findings of the study are that certain clinical parameters such as obesity and African American race as well as high scores on certain validated questionnaires (such as the pediatric sleep questionnaire- PSQ) are associated, but cannot predict OSA severity. PSG remains the only way to measure objectively the severity of OSA. (more…)

Dr. Ricardo Mosquera MD Assistant professor of Pediatrics at The University of Texas Health Science Center at Houston Medical School Clinic Director, UT Physicians, of the UTHealth Medical School.MedicalResearch.com Interview with: Dr. Ricardo Mosquera MD Assistant professor of Pediatrics at The University of Texas Health Science Center at Houston Medical School Clinic Director, UT Physicians, of the UTHealth Medical School. Medical Research: What is the background for this study? What are the main findings? Dr. Mosquera: There is not strong scientific evidence to support the use of medical homes.  Medical homes have not been demonstrated to decrease adverse outcomes or costs in children. Such benefits are most likely for high-risk children with chronic illness.  We conducted a rigorous and well designed, randomized controlled trial to determine if an enhanced medical home providing comprehensive care decreases serious illness  (death, prolonged hospitalization>7 days, or intensive care unit admissions) and/or cost among high-risk chronically ill children. An enhanced medical home decreased both adverse outcomes (decreased serious illness, hospitalizations, PICU admissions, and serious illness by ~50%) and cost (~$10.000 less per child/year). (more…)

MedicalResearch.com Interview with: Femi Oshin Consultant in Communicable Disease Control Devon, Cornwall & Somerset PHE Centre and Dan Murphy Cornwall & Isles of Scilly Health Protection Team, Cornwall, UK Medical Research: What is the background for this study? What are the main findings? Response: Salmonella disease are significant infections, particularly so in children. Ownership of reptiles kept as pets has risen sharply in recent years, as has Salmonella infections in children. Our study found children living in homes with a reptile as a pet are more likely to require hospitalisation from Salmonella infection, and the risk appears to increase with decreasing age of the child.

Ying Xu Assistant Professor, Ph.D. Department of Civil, Architectural and Environmental Engineering University of Texas, AustinMedicalResearch.com Interview with: Ying Xu Assistant Professor, Ph.D. Department of Civil, Architectural and Environmental Engineering University of Texas, Austin Medical Research: What is the background for this study? What are the main findings? Response: Phthalates have been widely used as plasticizers to enhance the flexibility of polyvinyl chloride (PVC) products.  They are ubiquitous and persistent indoor pollutants and may result in profound and irreversible changes in the development of human reproductive tract. In this study, we found that the emissions of phthalates and phthalate alternatives increase significantly with increasing temperature.  We developed an emission model and validated the model via chamber experiments.  Further analysis showed that, in infant sleep microenvironments, an increase in the temperature of mattress can cause a significant increase in emission of phthalates from the mattress cover and make the concentration in breathing zone about four times higher than that in the room, resulting in potentially high exposure.  In residential homes, an increase in the temperature from 25 to 35 ºC can elevate the gas-phase concentration of phthalates by more than a factor of 10, but the total airborne concentration may not increase that much for less volatile compounds.

Ann J. Melvin MD, MPH Division of Pediatric Infectious Disease Department of Pediatrics Seattle Children's Hospital, Seattle, WA 98105.MedicalResearch.com Interview with: Ann J. Melvin MD, MPH Division of Pediatric Infectious Disease Department of Pediatrics Seattle Children's Hospital, Seattle, WA 98105. Medical Research: What is the background for this study? What are the main findings? Dr. Melvin: While relatively uncommon, neonatal Herpes Simplex Virus is a potentially devastating infection with significant morbidity and mortality.  We reviewed all of the neonatal HSV cases treated at our institution between 1993 and 2012 who had HSV DNA PCR results available from the plasma and/or CSF.  Most of the infants had quantitative PCR results available.  The objective of the study was to determine the clinical correlation of HSV PCR levels in the plasma and CSF.  We found a clear association between the plasma HSV level, clinical presentation and mortality.  All of the infants who died had HSV plasma DNA levels of greater than 7 log10 copies/ml.   However, neither plasma nor CSF HSV levels predicted neurologic outcome.   Clinical evidence of CNS disease was more predictive of neurologic outcome than was the CSF PCR level. We also showed the most sensitive test for diagnosis of neonatal HSV to be HSV PCR on the plasma.  However, no single test diagnostic test (plasma PCR, CSF PCR, surface cultures) was positive across all infants, so it is important to obtain samples from plasma, CSF and surface swabs in infants with symptoms consistent with HSV infection.

Dr. Gary A. Smith Center for Injury Research and Policy Nationwide Children’s HospitalMedicalResearch.com Interview with: Dr. Gary A. Smith Center for Injury Research and Policy Nationwide Children’s Hospital   Medical Research: What is the background for this study? What are the main findings? Dr. Smith: The study found that from 1990 through 2011, an estimated 3,278,073 children younger than 18 years of age were treated in United States emergency departments for toy related injuries. The annual injury rate per 10,000 children increased by nearly 40% during that time period. The increase was largely associated with ride-on toys, particularly foot-powered scooters. Ride-on toys accounted for 34.9% of all injuries and 42.5% of hospital admissions. The study is the first to comprehensively investigate toy-related injuries among children using a nationally representative data set, the National Electronic Injury Surveillance System (NEISS).

MedicalResearch.com Interview with Rosemary Dodds Senior Policy Adviser NCT (formerly National Childbirth Trust), London, UK Medical Research: What is the background for this study? What are the main findings? Response: The study, which was commissioned by UNICEF UK, was designed to take an in-depth look at how raising breastfeeding rates might save money for the health service through reducing illness. It found that low breastfeeding rates in the UK are costing the health service millions of pounds.  We calculated that from reducing rates of illnesses, where the evidence is strongest, moderate increases in breastfeeding could see potential annual savings to the health service of around £40m per year. It should be noted however, that this figure is likely to be only the tip of the iceberg when the full range of conditions affected by breastfeeding are taken into account. Economic models around five illnesses (breast cancer in the mother, and gastroenteritis, respiratory infections, middle ear infections and necrotising enterocolitis (NEC) in the baby), show that moderate increases in breastfeeding would translate into the following cost savings for the NHS:
  •  If half those mothers who currently do not breastfeed were to do so for up to 18 months over their life, there would be:
-      865 fewer cases of breast cancer -      With cost savings to the NHS of over £21million -      Improved quality of life equating to more than £10million[1] Over the lifetime of each annual cohort of first-time mothers.
  • If 45% of babies were exclusively breastfed for four months, and if 75% of babies in neonatal units were breastfeeding at discharge, each year there would be:
-      3,285 fewer babies hospitalised with gastroenteritis and 10,637 fewer GP consultations, saving more than £3.6million -      5,916 fewer babies hospitalised with respiratory illness, and 22,248 fewer GP consultations, saving around £6.7million -      21,045 fewer GP visits for ear infection, saving £750,000 -      361 fewer cases of the potentially fatal disease necrotising enterocolitis, saving more than £6million (more…)

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.

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…)

Sigal, MD, MPH, FRCPC Professor of Medicine, Kinesiology, Cardiac Sciences and Community Health Sciences Division of Endocrinology and Metabolism, Cumming School of Medicine, University of Calgary Health Senior Scholar, Alberta Innovates-Health Solutions Member, O'Brien Institute of Public Health, Libin Cardiovascular Institute and Julia McFarlane Diabetes Research Centre Medical Research: What are the main findings of the study? 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.
