Response: Adolescent depression is one of the most common mental health conditions during adolescence. Up to one in five adolescents experience an episode of major depression by age 18. Depressed youth are at greater risk of suicide, dropping out of school and poor long-term health. Treatments, including medications and psychotherapy, have been proven to be effective but most depressed teens don’t receive any treatment.
Two years ago, we showed that the Reaching Out to Adolescents in Distress (ROAD) collaborative care model (a.k.a. Reach Out 4 Teens) designed to increase support and the delivery of evidence-based treatments in primary care was effective in treating depression in teens, significantly improving outcomes. We ran a randomized clinical trial at nine of Group Health’s primary care clinics and reported effectiveness results in JAMA.
The current paper represents the next step in this work, examining the cost-effectiveness of collaborative care for adolescent depression in our intervention sample of 101 adolescents with depression, ages 13-17 years.

Editors' note: Please discuss food introduction with your child's pediatrician before embarking on any new foods.
Response: Food allergy is a common problem which may be getting more common.
We have known for over 100 years that feeding egg to animals such as guinea pigs can prevent egg allergy. However randomised trials of allergenic food introduction for preventing food allergy in human infants have not been done until the past 5 years, and have so far yielded mixed results. One trial for peanut allergy was positive, with less peanut allergy in infants who were fed the food from early in life compared with infants who avoided it for 5 years. Other trials have yielded null findings, but may have been too small to yield a conclusive result. We used a technique called meta-analysis to combine the results of all previous trials of timing of allergenic food introduction and risk of food allergy. We also evaluated other allergic and autoimmune diseases.
Our analysis yielded conclusive results for both egg and peanut – that early introduction of these foods into an infant’s diet might reduce their risk of egg and peanut allergy by around 40-70%. We were surprised to see null findings in our meta-analysis of timing of gluten or wheat introduction and risk of coeliac disease (gluten intolerance) which is a different type of allergy to egg and peanut allergy. This suggests that early introduction of allergenic foods does not reduce risk of all types of food allergy.

Response: The study start from previous observations showing an association between the gut microbiota and obesity.
Similarly to what previously described in adults and in children, we found an association between the gut microbiota and obesity. We took a step further and also observed that the gut flora is associated to body fat partitioning (amount of fat in the abdomen). Moreover, we observed that the effect of microbiota could be mediated by the short chain fatty acids a product of gut flora.

Response: Project EAT (Eating and Activity in Teens and Young Adults) is on ongoing longitudinal study which began by screening middle and secondary school students in the Minneapolis and St Paul Metropolitan are. Students were the 11-18 years old (average age 15), then followed up at average ages 20 and 25. We had devised an eating pattern in about 2006, which
a) predicts a lot of things in several different studies (including total mortality in the Iowa Women's Health Study) and b) looks a great deal like the recently released 2015 Dietary Guidelines for Americans (DGA).
We call our diet pattern A Priori Diet Quality Score (APDQS) and think of it as close to or in the style of a Mediterranean/prudent/healthy diet.
We hypothesized that this pattern would be associated with lower weight (in general with better long term health, but the focus in Project EAT was weight and BMI), probably least so at age 15. The minimal hypothesized effect in adolescence relates to the very large energy expenditure in adolescent growth years; we thought that diet composition would be less important for body weight at that time than energy intake (and APDQS is about diet composition).

Response: Lead exposure among children is linked to many adverse effects on health and cognitive development, which can be irreversible. The National Center for Health Statistics (NCHS) has linked 1999 to 2012 National Health and Nutrition Examination Survey (NHANES) data to administrative data for the Department of Housing and Urban Development’s (HUD) largest rental assistance programs (1999 through 2014), and these linked data allow calculation of the first-ever national blood lead level estimates among children living in HUD-assisted housing. Here we compare blood lead levels among children 1 to 5 years of age in 2005 to 2012 who received housing assistance during 1999 to 2014 with levels among children who did not receive housing assistance during that period.

Response: The pros and cons of video gaming in children have been extensively debated. There are relevant amounts of data indicating both the positive and negative effects of video games. Nevertheless, a key question for many parents remains unanswered: How long should children play? To provide some clarity, we have investigated the relationship between weekly video game use and certain cognitive abilities and conduct-related problems.

Response: In the US, food allergy has become one of the more common childhood medical conditions diagnosed in young children. Antibiotics are frequently prescribed in young children, and research continues to reveal that as many as 30% of antibiotic prescriptions are not appropriate.* We sought to examine if there was an association between antibiotic prescription and food allergy diagnosis.

Response: As a group we were concerned about the misinformation that continues to be promulgated on the internet and through other sites. Importantly, the group consisted of experts with specific experience in the management of head louse infestations, from pediatric dermatology, pediatrics, school nursing and head louse research fields. Even information sources that we would have expected to be credible are outdated, unreliable or both, often continuing myths about head louse infestations and how they can be controlled. We wanted to provide a balanced and informed perspective that would help physicians and parents recognize that head louse infestations do not present a serious problem, and can be well managed with an informed approach to treatment.
The main findings are that over the counder products (permethrin/pyrethrins) are unlikely to be effective, and that that there are safe and effective products that are available by prescription.
Interestingly, head lice do affect Indian and African children in their home countries, but virtually nonexistent in African Americans in North America. There has been speculation about hair grooming regimen or structure of African American hair but the cause is unknown. In a study we performed assessing resistance to over the counter pediculicide components over a decade ago in Baltimore, we were not able to find a single African American child with head lice. We were not able to recruit any patients from the Baltimore City Schools.

Response: Surviving childhood cancer has dramatically and increasing improved to the point where more than 80% will achieve a 5-year event free survival. Many of these survivors look forward to decades of active productive life.
More than half of these survivors have been treated with therapies know to be associated with late cardiotoxicity that can be pervasive, persistent, and progressive and associated with cardiovascular morbidity and mortality. In this article we review both the course and prevention of this cardiotoxicity. We focus in part on anthracycline chemotherapy that is widely used and known to be cardiotoxicity.
We further review studies we and others have conducted to examine the effectiveness of dexrazoxane, an iron chelator, that when given before each anthracycline dose results in anthracycline cardioprotection for long term survivors. In some reported studies this has allowed for higher cumulative anthracycline doses to be safely given. In other cases this has allowed for simultaneously being able to safely treat children with malignancies that would be refractory to conventional therapy more potent therapies that would normally have additive cardiotoxicity.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The management of asthma attacks in preschoolers has been the subject of much recent debate. The results of a study published in 2009 had shaken the pediatric world. The study reported that preschool children with viral-triggered flare-ups did not respond to standard treatment and, suggesting that this was due to their young age. Such finding was particularly worrisome as the majority of asthma-related emergency room visits and hospitalizations involve preschool children.
We conducted this large cohort study in which children aged 1 to 17 years with a moderate or severe asthma attack were treated using the established evidence-based therapy adjusted to the severity of exacerbation assessed by the Pediatric Respiratory Assessment Measure (PRAM), administered rapidly. We explored the determinants of the failure of emergency therapy. Age was not a factor. Instead, in addition to attack severity and symptoms between attacks, it was rather the presence of respiratory viral infection or fever triggering the attack that was more often associated with treatment failure, i.e., higher hospitalization rates, more returns to the emergency room, and reduced speed of recovery over the 10 days after discharge. Viral detection occurred more frequently in preschoolers (67%) than in older children (46%) with asthma.
Nevertheless, the results confirm the overall effectiveness of standard treatment, adjusted to the severity of the attack and administered early, in the vast majority of children, regardless of age and viral detection. Indeed, although a failure rate of nearly 40% was expected in this group of children with moderate to severe attack, only 17% of the participants did not respond to standard treatment. This rate was significantly higher (19%) in children with viral infection compared to uninfected children (13%).

Response: Vitamin D is essential for calcium and bone metabolism. It is unique among vitamins in that it is mainly derived from synthesis in the
skin after exposure to UV-B radiation. In the absence of fortification, few foods are rich in vitamin D, including human milk, which contains very low amounts. Breastfeeding infants in higher latitude countries such as New Zealand, much of North America and
Central/Northern Europe are at risk of vitamin D deficiency.
The most profound manifestation of vitamin D deficiency in growing children is rickets, characterized by bone deformities, impaired growth, biochemical abnormalities, and depending on the severity of deficiency, seizures. Studies also identified a number of common factors that potentially affect the risk of rickets, including darker pigmented skin, maternal vitamin D deficiency during pregnancy, season of birth, and age.
A potential alternative strategy to improve the vitamin D status of breastfed infants is high-dose vitamin D supplementation to pregnant and lactating women. This would be attractive from a compliance perspective, promote exclusive breastfeeding, and treat both the mother and her infant.
Thus, the primary aim of this randomized, placebo-controlled study was to determine the effect of two different monthly doses of maternal vitamin D supplementation on the vitamin D status of non–vitamin D–supplemented breastfed infants and their mothers.

Response: Infant temperament, or individual behavior styles, can be reliably measured and is related to weight status. However, we know very little about the association of infants’ temperament and their motivation to eat versus engage in other activities (relative food reinforcement). Examining such associations is an important step given the need to use behavioral strategies in obesity prevention in early life. The purpose of our study was to determine if infant temperament, specifically the factors that have been linked with obesity risk, are associated with infant relative food reinforcement.

Response: Some studies have found that maternal gestational diabetes mellitus (GDM) places offspring at increased risk of long-term adverse outcomes, including obesity. However, most of studies are from high income countries, with limited data from low to middle income countries. The present study, conducted at urban and suburban sites in 12 countries, found that the increased risk for children of GDM mothers compared with non-gestational diabetes mellitus mothers was 53% for obesity, 73% for central obesity, and 42% for high body fat.

Response: Acetaminophen (e.g., Tylenol, Panadol) and ibuprofen (e.g., Advil, Motrin) are the only available treatments for pain and fever in toddlers and the most commonly utilized medications worldwide. Recently there has been controversy and even alarm with suggestive observational data that acetaminophen makes asthma worse. This has led some experts to recommend the avoidance of acetaminophen in children with asthma. We sought to find the answer to this burning question through the first prospective, double-blind, randomized clinical trial comparing acetaminophen versus ibuprofen head to head for use when clinically indicated for fever or pain. Is there a difference in asthma morbidity (exacerbations) in young children between the age of 12-59 months, who have asthma?

Response: The background for this study is that in the U.S, the Advisory Committee on Immunization Practices (ACIP), the committee that advises the CDC on vaccination policy, decided this June not to recommend LAIV (nasal live vaccine) for children. This is because of non-randomized studies conducted in the U.S suggesting that the vaccine was ineffective. This was an unprecedented decision in influenza vaccine policy making for children.
Our study, a randomized, blinded, controlled trial, which is the most rigorous type of study design, conducted over 3 years (2012-13, 2013-2014, 2014-2015 influenza seasons), showed in fact very similar protection for children and their communities for the live and inactivated vaccines. We conducted the study in the Hutterite community of Western Canada which allowed us to compare the effect of the vaccines in entire communities. That is, we were able to study the direct effect and the indirect effect of these vaccines.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Acetaminophen is considered safe to use during pregnancy. However, research suggests that acetaminophen use in pregnancy is associated with abnormal neurodevelopment. It is possible that this association might be confounded by unmeasured behavioural factors linked to acetaminophen use. We compared acetaminophen use during pregnancy to postnatal acetaminophen use and partner's acetaminophen use. Only acetaminophen use during pregnancy has the potential to cause behavioural problems in the offspring. Any associations with postnatal acetaminophen use and partner's acetaminophen use would be due to confounding. Behavioural problems in the offspring were only associated with acetaminophen use during pregnancy.

MedicalResearch.com: What is the background for this recommendation?
Response: The Task Force recognizes the importance of cardiovascular health for young people. Children and adolescents with high cholesterol are more likely to become adults with high cholesterol, and high cholesterol in adulthood can lead to serious health outcomes such as heart attacks and strokes. However, when the Task Force reviewed evidence for cholesterol screening in children and adolescents without any signs or symptoms, we found that there is not enough evidence to recommend for or against screening. In the face of unclear evidence, the Task Force is calling on the research community to prioritize studies on screening and treatment of lipid disorders in children and teens to help us all learn more about the impact that screening at an early age may have on the cardiovascular health of adults.

MedicalResearch.com: Would you tell us a little about your background? How did you develop an interest in pain management and prevention?
[caption id="attachment_26993" align="alignleft" width="164"]
Dr. Amy Baxter[/caption]
Response: As a pediatric emergency doctor, I found it interesting that doctors could prevent pain but sometimes couldn't be bothered to do so. The lack of empathy and impatience is built into emergency training - we learn to diagnose and fix things quickly, not comfort and support. I decided to research how pain management would make procedures more successful, or faster, to convince doctors to use pain management for THEIR benefit.
MedicalResearch.com: What is the background for the Buzzy(r) device? How does it impact pain sensation?
Response: When my 4 year old had a horrible vaccination experience, I realized that a fast effective parent-controlled option for pain relief was needed. I knew that cold running water could eliminate the pain from a burned finger using physiology called gate control. Basically, the small pain nerves run alongside big motion nerves, so if you heavily stimulate motion you scramble the pain sensation. Rubbing a bumped elbow is another good example. Vibration alone didn't work enough for needles, but when I added ice the two sensations of cold and motion eliminated pain in 84% of seniors getting a flu shot. We got a grant from the NIH to develop and study Buzzy - it's a palm sized vibration unit with a place on the back to attach ice "wings", that freeze solid. You put them both where an injection will go for a minute or less, then move them "between the brain and the pain" while doing a needle procedure. There are about 14 studies on IV access or blood draws and 6 on injections, showing between 50 and 88% pain reduction.
Several studies have demonstrated that Buzzy is truly a physiologic intervention, not a distraction: it didn't work for injections when only used for 10 seconds, too little time to block the pain nerves. But it worked really well for blood draws in severely cognitively impaired children for whom distraction wasn't an option.

Response: Acute otitis media (AOM) is a prime reason for doctor consultations and antibiotic use in children. Although symptoms of AOM may resolve spontaneously, these infections have a significant impact on child and family life and carry a considerable health care and economic burden. Acute otitis media occurring early in life, also called early-onset AOM, has been suggested as a risk factor for subsequent Acute otitis media episodes during childhood and could therefore also impact health care resource use. Identifying the critical age-period and quantifying the long-term consequences of early-onset AOM is important to guide future management and prevention programs aiming to reduce the burden of AOM.

MedicalResearch.com: What is the background for this study?
Response: This wasn’t a study, but rather a study of studies, to support the US Preventive Services Task Force in updating its previous recommendation of
I: insufficient to assess the balance of benefits and harms. We conducted two systematic evidence reviews of screening children and adolescents:
1. for familial hypercholesterolemia (FH, a genetic disorder that interferes with the body’s ability to metabolize cholesterol and can result in early coronary heart disease); and
2. for multifactorial dyslipidemia—which we defined as elevated LDL cholesterol or total cholesterol, not caused by familial hypercholesterolemia. LDL and total cholesterol were of interest because they are considered atherogenic.
One of the challenges of lipid screening in youth is that blood levels of these atherogenic lipids are known to fluctuate during the course of childhood and adolescence. It’s sort of a W-shaped curve, with a peak at age 9-11 years. So for a given child, the definition of what’s an elevated LDL or total cholesterol level will change with age. Also, two-thirds of kids identified as having high cholesterol through universal screening would not go on to have high cholesterol as adults.
