The UEFA Europa League takes centre stage in Turin this week but the grassroots are never forgotten, with events held at a famous city square and a juvenile detention centre.

"Are all my elves ready? OK, off we go!" A group of Santa and his elves head out into Karuizawa, Japan, to share God’s love.

Teaching via combined languages is important, as multiple races and immigrants from different countries live in the United States.

Former Vice President Joe Biden’s recent remarks on his willingness to work with segregationists resurrected his long-ago efforts to oppose school busing. Will it hurt his campaign?

The current standard of care includes informing women about prenatal testing and newborn screening for cystic fibrosis and providing genetic counseling to parents whose child is referred for sweat-testing. Despite counseling, early data identified some persistent confusion about residual risk.

Prenatal discussions about carrier testing and newborn screening for cystic fibrosis are not routine. Parental anxiety about abnormal results from a screen is decreased after speaking to a genetic counselor when scheduling the sweat test. Despite counseling, residual risk continues to be poorly understood. (Read the full article)

Several correlational studies documented that participants who would be classified as "pathological" video gamers demonstrate a pattern of correlations with other variables that are comorbid (eg, depression) or occur with (eg, poorer grades and increased hostility) other addictions.

Following a large sample across 2 years, this study provides needed data on risk factors for becoming a pathological gamer, how long pathological gaming lasts, outcomes, and whether it is a primary problem or is a symptom of comorbid problems. (Read the full article)

It has been well documented that exposure to tobacco marketing is a risk factor for smoking initiation among youth. However, few studies have tested the specificity of this association.

This study extends findings from other studies and shows (from a longitudinal design) that exposure to cigarette advertising is significantly associated with youth smoking initiation, whereas exposure to advertising for other commercial products is not. (Read the full article)

Approximately 27% of children with rotavirus in the hospital acquire it while hospitalized for another condition. Pediatric rotavirus vaccination greatly decreased the number of children hospitalized with rotavirus from 2007 to 2008.

Routine community-based rotavirus infant vaccination protects hospitalized children from acquiring rotavirus. Thus, community-based vaccination efforts should be encouraged as a strategy to decrease hospital-acquired rotavirus. (Read the full article)

Although gastroenteritis guidelines describe the need to perform oral rehydration, it remains underused, resulting in excessive use of intravenous rehydration. Other interventions, such as antiemetic administration, vary according to location, often resulting in differences in cost and outcomes.

In this nationwide cohort, intravenous rehydration use varied dramatically. Use was associated with the institution providing care and an increase in the need for future health care provider visits. Use of ondansetron also varied significantly across Canada. (Read the full article)

Gallbladder disease in children is an evolving entity and studies suggest an increasing frequency of symptomatic pediatric gallbladder disease and resultant cholecystectomies.

Hispanic ethnicity and obesity are epidemiologically significant risk factors for symptomatic gallbladder disease in the pediatric population. (Read the full article)

Lactoferrin is a glycoprotein with anti-infective activities being part of the innate defensive network. Bovine and human lactoferrin share high homology. Bovine lactoferrin can prevent late-onset sepsis in preterm very low birth weight neonates.

In preterm very low birth weight infants, bovine lactoferrin is able to prevent not only late-onset sepsis but also systemic fungal infections. This protection is achieved independently from their colonization status. (Read the full article)

Several studies have focused on birth weight heritability, reporting results that range between 40% and 80%. Few studies have focused on the process of weight gain and were mainly based on heterogeneous samples of infants.

The present work looks at a uniform set of healthy preterm newborn twins. The resulting high heritability estimate could suggest using the inclusion criteria to identify genes that regulate postnatal weight gain or failure. (Read the full article)

Newborn screening (NBS) programs may store bloodspot samples and use them for secondary purposes, such as research. Recent public controversies and lawsuits over storage and secondary uses underscore the need to engage the public on these issues.

This public engagement study identifies values underlying citizens’ acceptance of and discomfort with research from NBS samples. Well-designed methods of public education and civic discourse on the risks and benefits of storage and secondary uses of NBS samples are required. (Read the full article)

The retention and use of residual bloodspots is a practice of many state newborn screening programs. This practice has become controversial, and little is known about public attitudes on the retention and research use of newborn residual bloodspots.

This study offers a detailed analysis of public attitudes regarding bloodspot retention and use for biomedical research. The results also offer insights on how education regarding this practice influences support for newborn screening and residual bloodspot use. (Read the full article)

Impaired fetal growth is an independent risk factor for cardiovascular diseases in adulthood and is associated with arterial wall thickening, a noninvasive measure of subclinical atherosclerosis, in early childhood. No preventive strategy has been identified.

Dietary omega-3 fatty acid supplementation in early childhood prevented the association of impaired fetal growth with arterial wall thickening, suggesting that this early-life intervention may mitigate the risk of cardiovascular disease in those with impaired fetal growth. (Read the full article)

Active video games can enable children under laboratory conditions to participate in moderate, and even vigorous, physical activity. There are inconsistencies in the literature, however, about whether active video games enable children to increase physical activity under more naturalistic circumstances.

This study tests whether children receiving a new active video game spontaneously engaged in more physical activity, and whether commercially available active video games have a public health benefit. No additional physical activity was detected, suggesting no public health benefit. (Read the full article)

Emergency contraception is a safe and effective method of pregnancy prevention after unprotected intercourse.

Pharmacies commonly communicate misinformation, both to adolescents and to physicians, concerning who is able to access emergency contraception and through what means. (Read the full article)

Estimates of youth participation in strangulation activity, commonly referred to as the "choking game," range from 5% to 11%. Previous studies have documented correlations between youth choking game participation and health risks such as substance use and mental health issues.

Among Oregon eighth-graders surveyed, >6% had ever participated in the choking game. Participation was linked to poor nutrition and gambling among females, exposure to violence among males, and sexual activity and substance use among both genders. (Read the full article)

Cross-sectional imaging can reduce the negative appendectomy rate (NAR) in children being evaluated for suspected appendicitis; however, the ability of diagnostic imaging to decrease NAR may vary by age and gender.

Cross-sectional imaging leads to a significant reduction in NAR for children younger than 5 years and girls older than 10 years. For boys older than 5 years being evaluated for uncomplicated appendicitis, advanced imaging appears to have limited value. (Read the full article)

Dimenhydrinate, an antihistaminic agent, is a widely used drug in Canada and Europe. It limits stimulation of the vomiting center via the vestibular system. Multiple studies have shown its effectiveness in the treatment of vertigo and postoperative nausea and vomiting.

Dimenhydrinate, when given orally, did not significantly decrease the frequency of vomiting in children with acute gastroenteritis compared with placebo. The reported adverse effect proportions were similar for the dimenhydrinate and placebo groups. (Read the full article)

Omega-3 fatty acids (O3FA) are commonly used as complementary treatments in pediatric psychiatric disorders, including Tourette’s disorder (TD), and are well known to have anti-inflammatory properties. However, no studies to date have examined the effects of O3FA on pediatric TD.

This is the first double-blind, placebo-controlled clinical trial of O3FA in pediatric TD. The results indicate that O3FA supplementation may be beneficial in the reduction of tic-related impairment for some children and adolescents with TD, but not tics per se. (Read the full article)

Although obesity is correlated with levels of systolic and diastolic blood pressure, there is little evidence if the increases in obesity over the last 40 years have resulted in increased blood pressure levels.

Despite increases in obesity in Bogalusa, Louisiana between 1974 and 1993, there was no increase in systolic or diastolic blood pressure levels. It should not be assumed that trends in high blood pressure have paralleled those for obesity. (Read the full article)

Fetal factors that predispose infants to necrotizing enterocolitis (NEC) have been extensively studied. Maternal factors that may affect future risk for NEC are less clear.

We hypothesized that maternal factors were the primary cause of NEC. Through a case-control design we determined that maternal smoking predisposes infants to the development of NEC. Our results highlight the importance of smoking cessation in pregnancy. (Read the full article)

Rotavirus is a major cause of acute gastroenteritis among children worldwide. Vaccines targeting rotavirus have been demonstrated to be highly efficacious against severe disease in clinical trials and postlicensure studies. Vaccine impact on mild gastroenteritis has not been well studied.

We used a novel surveillance platform consisting of telephone triage data to capture mild gastroenteritis not detected in other surveillance systems. Since rotavirus vaccine licensure, gastroenteritis-related call proportions have declined, and peak gastroenteritis-related calls are correlated with community norovirus circulation.

Electronic cigarettes are battery-powered devices that simulate tobacco cigarettes by vaporizing nicotine and other chemicals into an inhalable mist. They have gained popularity around the world, but little is known about their safety and addictive properties.

Among Polish youth, electronic cigarettes are the fourth most common source of nicotine after cigarettes, waterpipes, and snuff. For those aged between 15 and 24 years, ever use of an electronic cigarette was 20.9%, and 30-day use was 6.9%. (Read the full article)

The Apgar score is a convenient method to rapidly assess the clinical status of the newborn infant. Recent literature suggests Apgar scores vary widely in preterm infants.

The Apgar signs for respiratory effort, grimace, and muscle tone demonstrated considerable disagreement in preterm infants ≤28 weeks’ gestation. Disagreement exists despite the level of respiratory intervention, continuous positive airway pressure, or intubation, and is likely independent of gestational age. (Read the full article)

Exergaming offers a physical activity (PA) alternative for youth that may be attractive in our increasingly technophilic society. Exergaming increases PA and decreases sedentary time, but most exergame studies are clinically based and focus on measuring energy expenditure during exergaming.

One-quarter of adolescents exergamed at intensity levels that could help them achieve PA recommendations. Exergamers were more likely to be female, play nonactive video games, watch ≥2 hours of television per day, be stressed about weight, and be nonsmokers. (Read the full article)

Implementing expanded vaccination recommendations has challenged primary care providers, who administer the majority of vaccines in the United States. School-located vaccination has been proposed as a means of increasing vaccination rates while reducing the burden on primary care providers.

This study assesses physicians’ support for their patients’ receipt of vaccines in school. Additionally, it compares physicians’ support for adolescent versus influenza vaccination and compares support by insurance status of their patient. (Read the full article)

Children investigated for alleged maltreatment have considerable physical, mental health (MH), developmental, and educational needs and often do not receive services to address these needs. The prevalence/correlates of MH services use in the current challenging financial environment is unknown.

This study demonstrates the importance of medical providers and schools for receipt of MH services for these children, but shows disparities in MH service use between white and nonwhite children. Unlike earlier findings, MH service use declined over the follow-up. (Read the full article)

The use of metformin in pregnancy is increasing in the treatment of both gestational diabetes and polycystic ovary syndrome. Metformin crosses the placenta. Teratogenicity is not reported. Possible long-term effects are undetermined.

Intrauterine metformin exposure seems to have long-term effects on infant weight. At 1 year of age, infants born to women and exposed to metformin weigh more than those exposed to placebo in utero. (Read the full article)

Social and environmental risks related to substandard housing contribute to adverse health outcomes. Partnerships between the health care and legal systems can help families address such risks and help clinicians understand the legal context of health.

A medical-legal partnership colocated in a pediatric primary care setting identified and treated a large cluster of poor quality, substandard housing. Housing improvements were possible because of strong collaboration between clinicians, attorneys, community partners, and families. (Read the full article)

Postnatal growth restriction of preterm infants is a universal problem. Early "catch-up growth" has been associated with development of metabolic syndrome. In addition, preterm infants appear to be at major risk for developing increased adiposity and insulin resistance.

The consumption of a nutrient-enriched formula after hospital discharge may be beneficial in adequate for gestational age infants both in terms of head circumference growth and fat-free mass gain. (Read the full article)

Previous studies have found variable child care provider compliance with American Academy of Pediatrics child care illness exclusion guidelines and high rates of unnecessary exclusion of mildly ill children from child care.

Our study is the first to compare child care directors’ return-to-child care practices before the release of the new American Academy of Pediatrics return-to-child care guidelines and to describe the guidelines’ impact if actively adopted by child care providers. (Read the full article)

Some children with gastroenteritis fail to respond to oral rehydration. Subsequent interventions are dictated by regional preference. In North America, nasogastric rehydration is rarely administered. Caregiver and health care providers’ perspectives regarding its use have not been described previously.

Both caregivers and health care providers would select intravenous rehydration instead of nasogastric rehydration when oral rehydration fails. Greater knowledge mobilization efforts will be required for nasogastric rehydration to be adopted into clinical practice. (Read the full article)

Prenatal cocaine exposure is associated with the trajectories of childhood behavior problems. Exposure effects may also be related to maternal use of other substances during pregnancy, and risk factors other than prenatal exposure may augment the detrimental cocaine effects.

The balance between cumulative risk and protective indexes predicts behavior outcomes, independent of prenatal drug exposure. A high protective index even with a high level of risks can mitigate the detrimental effects of drug exposure on behavior problem trajectory. (Read the full article)

Physical inactivity is one of the major modifiable factors contributing to the growing national epidemic of childhood obesity. There is lack of literature on pedometer-determined physical activity (PA) during the school day in US minority kindergarten and first-grade students.

This is the first study to assess school-day PA in US urban minority kindergarten and first-grade students. Higher grade level, participation in physical education class, and outdoor recess were found to be independent predictors of PA. (Read the full article)

Sugar-sweetened beverage (SSB) consumption is associated with childhood obesity risk. Because dietary salt intake is a determinant of fluid consumption in adults, a high-salt diet may predict greater consumption of SSBs and therefore increase obesity risk.

In Australian children, the amount of salt consumed was positively associated with fluid consumption, and predicted the amount of SSB consumed. In addition, SSB consumption was associated with obesity risk, indicating a potential link between salt intake and childhood obesity. (Read the full article)

There is evidence that Kingella kingae, the major bacterial cause of osteoarticular infection in children <4 years of age, first colonizes the oropharynx before penetrating the bloodstream and invading distant organs. Diagnosis remains challenging because clinical findings at admission may be normal.

Our study demonstrated for the first time that a simple technique of detecting of K kingae DNA in the oropharynx can provide strong evidence that this microorganism is responsible for the OAI, or even stronger evidence that it is not. (Read the full article)

Most studies focus on health of foster children or local samples of young children. One previous study examined a national cohort longitudinally but did not address the full age group or range of conditions at the time of initial investigation.

Using 2 approaches to assess children (aged 0–17.5 years) who have chronic health conditions, we found that regardless of placement, investigated children had much higher rates of these conditions than the general population at the time of initial assessment. (Read the full article)

Delayed anaphylaxis, urticaria, and angioedema to mammalian meat products were first described in the adult population in 2009. Patients with this syndrome who consume mammalian meat typically develop symptoms 4 to 6 hours after ingestion.

Specific diagnoses for children who develop urticaria, angioedema, and idiopathic anaphylaxis are few and far between. We have now shown delayed anaphylaxis, urticaria, and angioedema due to mammalian meat products in the pediatric population. (Read the full article)

At least half of the achievement gap for low-income, minority children is present at kindergarten entry; however, there are no population-level early childhood interventions that effectively engage and support families and teachers to ameliorate the impact of adversity on achievement.

This study evaluated ParentCorps, a family-centered, school-based intervention to promote self-regulation and learning for all children entering school in disadvantaged, urban neighborhoods. ParentCorps results in higher kindergarten achievement among low-income, minority children. (Read the full article)

Blood lead levels well below 10 µg/dL are now recognized as causing adverse cognitive effects, including lower scores on standardized reading and math tests.

This is the first study to show that reading readiness early in kindergarten is independently associated with blood lead levels well below 10 µg/dL. Results suggest that lead exposure may have a larger impact on urban education than national estimates suggest. (Read the full article)

The gap between organ availability and need continues to grow, and infants are among the most vulnerable candidates on the wait-list. The scarcity of donor organs has led the transplant community to look for alternative donor sources.

Children are receiving more grafts from pediatric donors, but they also continue to receive adult donor grafts. Donation after circulatory determination of death increases organ availability. Allocation changes have also helped increase pediatric transplantation and decrease wait-list deaths. (Read the full article)

Excessive weight gain over the first 18 months of life may have consequences for later body size. However, the relationship of weight gain in this period to atherogenic risk factors in later childhood is not well characterized.

Early postnatal weight gain from birth to 18 months is independently associated with childhood overweight and obesity, excess central adiposity, and greater arterial wall thickness at age 8 years. (Read the full article)

Patients who are fed via gastrostomy tube represent a heterogeneous, complex group of patients who may be at increased risk for kidney stones. To date, no previous studies have examined risk factors for kidney stone development in this population.

This case-control study of risk factors for urolithiasis in patients fed via gastrostomy suggests that topiramate use, urinary infections, and shorter length of time with a gastrostomy tube (possibly a marker for dehydration) are all associated with stone development. (Read the full article)

Minority children are less likely than white children to be diagnosed and treated with attention-deficit/hyperactivity disorder. However, diagnosis patterns over time in early and middle childhood and whether confounding factors explain these disparities are not currently well understood.

Racial/ethnic disparities in attention-deficit/hyperactivity disorder diagnosis occur by kindergarten and continue until eighth grade. Racial/ethnic disparities among diagnosed children in medication use occur in both fifth and eighth grades. These disparities are not attributable to confounding factors. (Read the full article)

Pneumococcal conjugate vaccines are effective in preventing pneumococcal disease but are also costly. Although the current US immunization schedule recommends 4 doses, many countries have adopted 3-dose schedules that have worked well, but may provide less protection against pneumococcal disease.

Changing the US 13-valent pneumococcal conjugate vaccine schedule from 3 to 2 primary doses while keeping a booster dose would save $412 million annually but might lead to moderate increases in pneumococcal disease, especially otitis media and pneumonia. (Read the full article)

Children with autism spectrum disorder (ASD) and those with ADHD are at risk for problematic video game use. However, group differences in media use or in the factors associated with problematic video game use have not been studied.

Boys with ASD and ADHD demonstrated greater problematic video game use than did boys with typical development. Inattention was uniquely associated with problematic use for both groups, and role-playing game genre was associated with problematic use among the ASD group only. (Read the full article)

Sugar-sweetened beverage (SSB) consumption in school-age children and adolescents is linked to heavier weight, and decreased SSB consumption results in less weight gain. Reports regarding these associations among children aged 2 to 5 years have been mixed.

Preschool-aged and kindergarten children drinking SSB compared with infrequent/nondrinkers had higher BMI z scores. SSB consumption is also associated with higher weight status among children aged 2 to 5 years. (Read the full article)

Adolescents are likely to smoke if their parent(s) smoke. Little research uses prospective longitudinal data from parents and children to more confidently document these intergenerational associations, alongside potential confounders (parental education) and mediators (school achievement, mental health, older sibling smoking).

Analyses of long-term multigenerational data show how diverse parental smoking trajectories influence child smoking, controlling for measured confounders. The risk of smoking is especially high among children residing with a persistent heavy smoking parent and an older sibling who smokes. (Read the full article)
