MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Approximately 3500 babies die suddenly and unexpectedly during sleep in the US every year. Even though there are safe sleep recommendations, many parents do not follow them because of misinformation or misconceptions.

Therefore we tested 2 complementary interventions to promote infant safe sleep practices. The first was a nursing quality improvement intervention aimed at ensuring that mothers would hear key messages and that there was appropriate role modeling of safe sleep practices by hospital personnel.

The second was a mobile health intervention, in which mothers received videos and text messages or emails with safe sleep information during the baby’s first two months of life. We randomized mothers to receive either the safe sleep interventions or breast-feeding interventions (the control interventions). Mothers who received the mobile health intervention reported statistically significantly higher rates of placing their babies on their back, room sharing without bed sharing, no soft bedding use, and pacifier use, compared with mothers who received a control intervention. Although the nursing quality improvement intervention did not influence infant safe sleep practices, there was an interaction such that mothers who received both the safe sleep nursing quality improvement intervention and the safe sleep mobile health intervention had the highest rates of placing their babies on the back.

Stress of 911 Linked To Decrease In Male Babies Born With Birth Defects

MedicalResearch.com Interview with:
Parvati Singh B. Tech, MBA, MPA
PhD student, Department of Public Health,
University of California, Irvine and
Dr. Tim Bruckner, first author

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: This study builds upon earlier research by our group which showed that male fetal deaths rose and the number of liveborn males fell after the 9/11 attacks. Here we show that, in California, the number of live born males with birth defects fell after 9/11.

This finding appears consistent with the notion that frail male gestations, such as those with defects, may have been lost in utero as a result of the stress induced by the 9/11 attacks.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Newborn infants, placed skin-to-skin on their mother’s chest instinctively have the ability to crawl to their mother’s breast, exploring with their hands and massaging the breast to support the first feed.  Left undisturbed, the infant will make several attempts until it finds and latches onto the nipple and begins to nurse.

What leads mammalian infants who are placed on their mothers’ chests to seek out, without any assistance, the nipple and to attach themselves to it to nurse is not fully understood. When we turned our attention to the thermal properties of the female’s nipple-areolar complex (NAC) in lactating mothers soon after birth, we found that it had a higher temperature and pH value and lower elasticity with respect to the surrounding breast skin. We hypothesised that the higher temperature could help the newborn infant to locate the nipple and to latch onto it, leading to the first sucking experience.  In addition, the diffusion of odorous molecules is presumably enhanced by the relatively high surface temperature of the areola in view of the rich supply of blood capillaries that irrigate the region. There is, in fact, some scientific evidence that show that infants respond to the odours released by the breasts of lactating women; breast odours, which are enhanced by the skin’s greater warmth, are another factor that facilitates breastfeeding by helping the infant to recognize its mother participating in the mother-to-infant bonding.

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.

Dr. Melton

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.

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.

BLISS – Baby Led Introduction To Solids – May Make Feeding Less Fussy

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.

Effect of Depth and Duration of Cooling on Death or Disability at Age 18 Months Among Neonates With Hypoxic-Ischemic Encephalopathy

MedicalResearch.com Interview with:

Dr. Shankaran

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.

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.

Peter Carew Lead author, MCRI PhD student  Clinician

Peter Carew

Peter Carew
Lead author, MCRI PhD student

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.

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.

Aleksandra Jakubowski, MPH PhD candidate
Department of Health Policy and Management

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.

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: 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: 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.

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.

Maternal Obesity Linked To Increased Risk of Congenital Malformations in Offspring

MedicalResearch.com Interview with:
Dr. Martina Persson

Clinical Epidemiology Unit
Department of Medicine Solna
Karolinska University Hospita

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: It is well known that obesity increases risks of several maternal, fetal and neonatal complications including congenital malformations. However, it has not been clear if risks of malformations are increased also in offspring of normal weight mothers or if risks increase with degree of maternal obesity.

In this study, we found progressively increasing risks of major congenital malformations in the offspring with a mother’s overweight and obesity severity.

MedicalResearch.com: What should readers take away from your report?

Response: The most sensitive period of fetal organ development is the first eight weeks of gestation and it is during this time a mother´s BMI may influence risks of malformations. Thus, it is important to try to obtain a normal bodyweight before conception.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Response: Our results should be confirmed in other populations and mechanisms behind the increased risks of malformations associated with maternal obesity should be further explored.

MedicalResearch.com: Is there anything else you would like to add?

Response: Obesity is a major health problem in many countries in the world. Preventive measures to halt the obesity epidemic should be implemented at all levels of society.

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.

Epigenetic Changes Identified In Children Who Develop Early Onset Conduct Problems

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.

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).

Mackenzie Herzog

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.

Regular Adolescent Cannabis Users More Likely To Have Later Problems with Drugs, Alcohol and Tobacco

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.

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.

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.

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: 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.

Dr. Arora

Manish Arora, PhD
Associate Professor

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.

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: 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).

Babies As Young as 3-5 Months Taught To Stand

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: 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.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Bed-sharing, the unsafe practice in which parents sleep in the same bed as their babies, is associated with sleep-related deaths in infants, including sudden infant death syndrome (SIDS) and accidental suffocation and strangulation in bed. No studies have examined the effect of a Finnish-style baby box on infant sleep environment. Face-to-face postpartum education about safe infant sleep, combined with the distribution of a baby box, which is a cardboard bassinet, reduced the rates of bed-sharing during babies’ first 8 days of life.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: This study looked at a 21-year period – 1990 through 2010 – and focused on children younger than 18 years of age treated in U.S. hospital emergency departments for cotton tip applicator-related ear injuries. About 263,000 children were injured during the study period, which comes out to approximately 1000 injuries seen in emergency departments every month or 34 per day.

The majority of injuries occurred when cotton tip applicators were used to clean a child’s ear canal (73%), and most of those injuries occurred when a child was using a cotton tip applicator on their own (77%), or their parent was using the device (16%) to clean the ear canal. About two out of every three patients were younger than 8 years of age, and patients aged 0-3 years accounted for 40% of all injuries.

Surprisingly, the highest rate of injury was in children 0-3 years old. The most common injuries were foreign body sensation (30%), perforated ear drum (25%) and soft tissue injury (23%).

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: As pediatric emergency clinicians, unfortunately, many of us have cared for a number of children who have been victims of gun violence. We wanted to investigate whether gun laws may make a difference in the rates of firearm-related morbidity and mortality in children. We specifically were interested in emergency department visits because they relate directly to the care we provide to pediatric patients.

Our main findings from our five-year study were that children are affected by gun violence nationally and, specifically, we saw regional differences in emergency department visits made by children who were victims of firearm violence.

Overall, firearm-related visits by patients 21 and younger to emergency departments remained consistent over time at a rate of 65 per every 100,000 visits until 2013, when they decreased slightly to 51 per 100,000 visits.

We also found that regions with more strict gun laws had lower rates of emergency department visits by children for gun violence compared with those regions with less stringent laws. We used the Brady Score, which looks at various state gun laws and assigns a score, to measure strictness. Then, based on state-level scores, we created regional composite scores.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: There are about 3 million concussions in the US each year and the majority occur in children. Parents of children with concussions commonly cite length of recovery as a major concern, but pediatricians have no objective or accurate tests for addressing this concern.

Our research group previously identified small regulatory molecules called microRNAs that were altered in both the spinal fluid and saliva in children with traumatic brain injuries. In this study we investigated whether those microRNAs could predict duration of concussion symptoms. In 52 children with concussion we found a set of microRNAs that predict whether concussion symptoms would last beyond one month with over 80% accuracy. This was significantly more accurate than survey based tools such as the sports concussion assessment tool or a modified concussion clinical risk score. Interestingly, the microRNAs with predictive accuracy targeted pathways involved in brain repair and showed correlations with specific concussion symptoms.

MedicalResearch.com: What is the background for this study?

Response: Previous prospective studies have observed protective association between fish-derived fat and type 1 diabetes related autoimmunity in older children. Also some other fatty acids have been associated with the risk for type 1 diabetes associated autoimmunity. We wanted to study very young children, because type 1 diabetes associated autoimmunity often begins early, already in infancy. Therefore, we investigated whether serum fatty acid levels during infancy or the main dietary sources of fatty acids (breast milk and infant formula) were related to the development of autoimmunity responses among children at increased genetic risk of developing type 1 diabetes.

MedicalResearch.com: What is the background for this study?

Response: Inorganic arsenic is a human carcinogen, which has also been associated with several adverse health effects including neurological, cardiovascular, respiratory, and metabolic outcomes. Early life exposure is of particular concern since it may adversely impact on lifetime health outcomes. If low inorganic arsenic drinking water is available the main source of exposure is the diet, especially rice and rice-based products, which are widely used during weaning and to feed infants and young children. In order to reduce exposure, the EU has recently regulated (1st January 2016) the inorganic arsenic maximum level of 0.1 mg/kg for rice products addressed to infants and young children. This level is also under consideration by the US FDA.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Visual impairment in early childhood has profound impact on a child’s development. It can significantly impair development of visual, motor, and cognitive function1-3 and lead to adverse psychosocial consequences. There has been a lack of accurate data characterizing the current and expected numbers of visual impairment cases among preschool children in the United States from 2015 to 2060.

The number of preschool children with visual impairment is projected to increase by 26% in 2060. And 69% of these visual impairment will result from simple uncorrected refractive error such hyperopia and myopia, which can be prevented or treated by low-cost refractive correction.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Type 1 diabetes is a severe chronic disease in children. There are few established risk factors, but it has been hypothesized that factors related to reduction of microbial exposure in childhood may increase the risk. We have previously shown that children in dog-owning families are at lower risk for asthma, and we now wanted to investigate the relationship of dog ownership and diabetes. We did this by studying the whole Swedish child population with record linkage across registers of health and dog ownership. We could not find evidence for an association of dog ownership and type 1 diabetes in the general population.

Does Cell Phone Use During Pregnancy Increase Childhood Behavioral Problems?

MedicalResearch.com Interview with:
Laura Birks, MPH, Predoctoral Fellow

Instituto de Salud Global de Barcelona – Campus MAR
Barcelona Biomedical Research Park (PRBB) (office 183.01B)
Barcelona, Spain

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Previous studies in Denmark and the Netherlands have reported associations between prenatal cell phone use and child behavioral problems, but findings have been inconsistent and based on retrospective assessment of cell phone use. This study aimed to assess this association in a multi-national analysis, using data from three cohorts with prospective data on prenatal cell phone use, together with previously published data from two cohorts with retrospectively collected cell phone use data.

We found that cell phone use during pregnancy was associated with increased risk for behavioral problems in offspring, specifically hyperactivity/inattention problems. This association was fairly consistent across cohorts and between cohorts with retrospectively and prospectively collected cell phone use data. While our models were adjusted for many confounders, it is possible that other factors could explain this association, such as hyperactivity in the mother or parenting styles (variables that were not collected in these cohorts). Furthermore, to date there is no known biological mechanism that could explain the association.

MedicalResearch.com: What is the background for this study?

Response: The novelty of our study lies in its scale and scope. In terms of scope, it reported on six educational outcomes and three health outcomes in the same group of children.

In terms of scale, it is the first study of a whole country to compare educational outcomes of children with treated ADHD with their unaffected peers and is more than 20 times larger than previous studies on similar educational outcomes. The only previous countrywide study on health outcomes, included only children with very severe ADHD who were in psychiatric hospitals.

Many Teens Use Less Effective Contraceptives After Pregnancy

MedicalResearch.com Interview with:
Deborah L. Dee, PhD
Division of Reproductive Health

CDC

MedicalResearch.com: What is the background for this study?

Response: Although the national teen birth rate has dropped to a historic low (22.3 births per 1,000 females aged 15-19 years in 2015), many teens continue to have repeat births. Because repeat teen births are more likely than first teen births to be preterm and low birth weight, and giving birth more than once as a teenager can significantly limit a mother’s ability to attend school and obtain work experience, it’s important to assess patterns in repeat teen births and better understand contraceptive use within this population.

MedicalResearch.com: What is the background for this study?

Response: We wanted to identify promising strategies for providing access to HIV-testing for gay and bisexual male youth. We were especially interested in testing strategies to reach gay and bisexual male youth of color, as they bear a disproportionate burden of the HIV epidemic and are the least likely to be aware of their HIV status. We also wanted to explore approaches to successfully link these youth with HIV-negative test results to diverse HIV prevention services, including pre-exposure prophylaxis, when warranted.

Although some argue that the ideal place to test adolescents and young adults is via emergency rooms and in routine medical care visits, we found that we were able test many more youth with previously undiagnosed HIV-infection through intensive, targeted community outreach efforts. We also tested a much higher proportion of young men of color through targeted outreach.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: This research grew from my experience as a neonatal nurse. I have worked with many families preparing to take their baby home and have seen the anxiety they experience wondering if they will be able to take care of their baby’s medical needs at home.

Parents are usually most anxious about emergency situations that may occur. Majority of these parents are able to state what they should do, but have never experienced the actual situation with their baby. This study was designed to see if a simulation experience would fill this gap in parents’ preparation for the discharge of their baby from the NICU. This study had parents participated in a customized simulation to have them experience the care needed by their baby at home following discharge from the NICU.

The findings revealed that parents reported a nearly 30 percent increase in confidence in their abilities to care for their baby after participating in the simulation.

MedicalResearch.com: What is the background for this study?

Response: Bereavement by the death of a close relative is ranked as one of the most severe life events and it is likely to cause psychological stress regardless of coping mechanisms. An increased risk of mortality and adverse health outcomes has been observed among the bereaved spouses, parents, and children. It is estimated that nearly 8% of individuals in the US experienced a sibling death in childhood but much less is known about its health consequences. Sibling relationship tends to be the longest and the most intimate in family thus the death of a sibling can be a devastating life event, especially when this event happens at early ages. However, to our knowledge, no study has investigated the effects of sibling death in childhood on subsequent mortality in bereaved siblings with a long follow-up time.

Childhood Adversities Linked To Increased Suicide Risk in Adolescents and Young Adults

MedicalResearch.com Interview with:
Charlotte Björkenstam PhD

Dept of Clinical Neuroscience
Karolinska Institutet
Division of Insurance Medicine
Stockholm

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: In a prior study we revealed that exposure to childhood adversities were associated with a substantial risk increase for self-harm. The risk was even higher for those exposed to accumulated childhood adversities. This finding together with the fact that the suicide rate among young adults is increasing (as opposed to decreasing in the general population) lead us to want to examine the relationship between childhood adversities and death by suicide.

We investigated 7 different childhood adversities, including familial death (suicide analyzed separately), parental substance abuse, parental psychiatric disorder, substantial parental criminality, parental separation/single-parent household, public assistance recipiency, and residential instability occurring between birth and age 14. We then followed the individuals up until age 24 at most. All adversities were entailed with an increased suicide risk from IRR: 1.6 (95% CI: 1.1 to 2.4) for residential instability to IRR: 2.9 (95% CI; 1.4 to 5.9) for familial suicide. We also found a dose-response relationship between accumulating CA and suicide risk where IRR ranged between 1.1 (95% CI: 0.9 to 1.4) for those exposed to 1 CA, to 2.6 (95% CI: 1.9 to 3.4) for those exposed to 3 or more adversities.
