RESUMO
Introduction: Young, minority women are less likely to follow recommendations to prevent infant sleep-related deaths putting their children at risk. This study extended the past pre/post study designs to an RCT design and included both parent report and objective observation of the sleep environment. Objective: This study focused on this population in a quantitative, randomized controlled trial using a low-cost, brief educational intervention, a Safety Baby Shower (SBS). Methods: Pregnant teens aged 13-19 (N = 147) were recruited as a dyad with a senior female caregiver and randomized to intervention or control groups. Results: Comparing self-report, safe sleep knowledge, attitudes, beliefs, and intent (KABI) to act scores across the two groups found intervention dyads to have more positive views on all four constructs than controls. Specifically, intervention dyad young mothers were significantly more likely to have positive beliefs about safe sleep and were more likely to report intent to practice infant safe sleep than control young mothers. Intervention dyad young mothers also had higher self-efficacy related to infant safety and more positive attitudes about safe sleep practices than control young mothers. Observations at a home visit conducted after delivery found no differences in the safe sleep practices by intervention status. Participant report of behaviors at the home visit also showed no differences in the use of safe position between the intervention and control groups. Conclusion: It appears that even when young mothers gain knowledge and self-efficacy, they have difficulty implementing this knowledge. In practice, this suggests that exploring barriers prenatally with this population and offering suggestions to overcome them may be indicated.
RESUMO
Since all-terrain vehicles (ATVs) were introduced in the mid-1970s, regulatory agencies, injury prevention researchers, and pediatricians have documented their dangers to youth. Major risk factors, crash mechanisms, and injury patterns for children and adolescents have been well characterized. Despite this knowledge, preventing pediatric ATV-related deaths and injuries has proven difficult and has had limited success. This policy statement broadly summarizes key background information and provides detailed recommendations based on best practices. These recommendations are designed to provide all stakeholders with strategies that can be used to reduce the number of pediatric deaths and injuries resulting from youth riding on ATVs.

All-terrain vehicles (ATVs) represent a serious and ongoing public health and safety concern for children and adolescents. Survey studies indicate that high proportions of youth ride ATVs in both rural and nonrural populations. The significant human and economic costs of pediatric ATV-related deaths and injuries result from a number of major risk factors that are highly common in pediatric ATV crashes: operating adult-size vehicles, riding with or as passengers, lack of protective equipment, and riding on public roads. Other less well-studied but potentially significant risk factors are speed, riding at night, alcohol use among older teenagers, and lack of training and supervision. Although potentially safer than adult ATVs, youth models present a number of safety concerns that have not been addressed with rigorous study. The most common ATV crash mechanism is a noncollision event-for example, a rollover. Common injury mechanisms include ejection from the vehicle, resulting in extremity and head injuries, and being pinned or crushed by the vehicle with resulting multiorgan trauma and/or compression asphyxia. Traumatic brain injury and multisystem trauma are the 2 most common causes of death and disabling injury. Taken together, a large multidecade body of evidence is the basis for the American Academy of Pediatrics policy statement recommendation that no child younger than 16 years of age ride on an ATV. Because children continue to be allowed to ride these vehicles, however, efforts to prevent pediatric ATV-related deaths and injuries require multipronged strategies, including education of both youth and parents, safety-based engineering, and enforcement of evidence-based safety laws.

PURPOSE: Research demonstrates that children receive twice as much medical radiation from Computed Tomography (CT) scans performed at non-pediatric facilities as equivalent CTs performed at pediatric trauma centers (PTCs). In 2014, AFMC outreach staff educated Emergency Department (ED) staff on appropriate CT imaging utilization to reduce unnecessary medical radiation exposure. We set out to determine the educational campaign's impact on injured children received radiation dose. METHODS: All injured children who underwent CT imaging and were transferred to a Level I PTC during 2010 to 2013 (pre-campaign) and 2015 (post-campaign) were reviewed. Patient demographics, mode of transportation, ED length of stay, scanned body region, injury severity score, and trauma center level were analyzed. Median effective radiation dose (ERD) controlled for each variable, pre-campaign and post-campaign, was compared using Wilcoxon rank sum test. RESULTS: Three hundred eighty-five children under 17 years were transferred from 45 and 48 hospitals, pre- and post-campaign. Most (43%) transferring hospitals were urban or critical access hospitals (30%). Pre- and post-campaign patient demographics were similar. We analyzed 482 and 398 CT scans pre- and post-campaign. Overall, median ERD significantly decreased from 3.80 to 2.80. Abdominal CT scan ERD declined significantly from 7.2 to 4.13 (P-value 0.03). Head CT scan ERD declined from 3.27 to 2.45 (P-value < 0.0001). CONCLUSION: A statewide, CT scan educational campaign contributed to ERD decline (lower dose scans and fewer repeat scans) among transferred injured children seen at PTCs. State-level interventions are feasible and can be effective in changing radiology provider practices.
RESUMO
Plasticity is often implicated as a reparative mechanism when addressing structural and functional brain development in young children following traumatic brain injury (TBI); however, conventional imaging methods may not capture the complexities of post-trauma development. The present study examined the cingulum bundles and perforant pathways using diffusion tensor imaging (DTI) in 21 children and adolescents (ages 10-18 years) 5-15 years after sustaining early childhood TBI in comparison with 19 demographically-matched typically-developing children. Verbal memory and executive functioning were also evaluated and analyzed in relation to DTI metrics. Beyond the expected direction of quantitative DTI metrics in the TBI group, we also found qualitative differences in the streamline density of both pathways generated from DTI tractography in over half of those with early TBI. These children exhibited hypertrophic cingulum bundles relative to the comparison group, and the number of tract streamlines negatively correlated with age at injury, particularly in the late-developing anterior regions of the cingulum; however, streamline density did not relate to executive functioning. Although streamline density of the perforant pathway was not related to age at injury, streamline density of the left perforant pathway was significantly and positively related to verbal memory scores in those with TBI, and a moderate effect size was found in the right hemisphere. DTI tractography may provide insight into developmental plasticity in children post-injury. While traditional DTI metrics demonstrate expected relations to cognitive performance in group-based analyses, altered growth is reflected in the white matter structures themselves in some children several years post-injury. Whether this plasticity is adaptive or maladaptive, and whether the alterations are structure-specific, warrants further investigation.
RESUMO
This study investigated patterns of cortical organization in adolescents who had sustained a traumatic brain injury (TBI) during early childhood to determine ways in which early head injury may alter typical brain development. Increased gyrification in other patient populations is associated with polymicrogyria and aberrant development, but this has not been investigated in TBI. Seventeen adolescents (mean age = 14.1 ± 2.4) who sustained a TBI between 1-8 years of age, and 17 demographically-matched typically developing children (TDC) underwent a high-resolution, T1-weighted 3-Tesla magnetic resonance imaging (MRI) at 6-15 years post-injury. Cortical white matter volume and organization was measured using FreeSurfer's Local Gyrification Index (LGI). Despite a lack of significant difference in white matter volume, participants with TBI demonstrated significantly increased LGI in several cortical regions that are among those latest to mature in normal development, including left parietal association areas, bilateral dorsolateral and medial frontal areas, and the right posterior temporal gyrus, relative to the TDC group. Additionally, there was no evidence of increased surface area in the regions that demonstrated increased LGI. Higher Vineland-II Socialization scores were associated with decreased LGI in right frontal and temporal regions. The present results suggest an altered pattern of expected development in cortical gyrification in the TBI group, with changes in late-developing frontal and parietal association areas. Such changes in brain structure may underlie cognitive and behavioral deficits associated with pediatric TBI. Alternatively, increased gyrification following TBI may represent a compensatory mechanism that allows for typical development of cortical surface area, despite reduced brain volume.

BACKGROUND: Firearm-related injuries are the second leading cause of death among US children. Given this, firearm injury prevention should be a key aspect of pediatric anticipatory guidance. OBJECTIVE: We assessed the impact of a firearm safety counseling workshop on pediatric resident knowledge, self-efficacy, and self-reported practice patterns. METHODS: Sixty of 80 residents (75%) participated in a 2-hour multimodal workshop, including video, didactics with experts, and role-play scenarios. Participants were invited to complete pre-workshop, immediate post-workshop, and 3- and 6-month post-workshop self-reported questionnaires evaluating knowledge, comfort, perceived barriers, and reported practice patterns. Data comparing pre- and 6-month post-workshop practice patterns were analyzed via Fischer's exact test. Remaining statistical analysis utilized a one-sided, unpaired Mann-Whitney U test. A binomial exact proportions test was used for open-ended responses. RESULTS: After the workshop, the percentage of participants with perceived concern regarding parental barriers decreased significantly (24% to 7%, P = .001). Participants 6 months post-workshop were 5.14 times more likely to counsel their patients on firearms during more than 75% of their well visits than prior to the intervention (P = .010). Participants reported greater comfort asking patients about firearms, with mean Likert scores increasing from 3.81 pre to 4.33 post (P = .022), which was similar to 3-month (4.39, P = .06) and 6-month evaluations (4.54, P = .003). CONCLUSIONS: Education on firearm safety counseling improved pediatric resident comfort level in discussing the topic. This impact persisted 6 months after the workshop, implying a sustained change in attitudes and behaviors.

Sudden Infant Death Syndrome (SIDS) and suffocation account for more than half of all Sudden Unexpected Infant Deaths (SUID) and are leading causes of post-neonatal deaths. Risk reduction strategies, including supine sleep position and safe sleep environment, are critical for prevention. Teen mothers, especially those in rural, poor, southern states, are at higher risk due to low compliance with recommendations. We will conduct a randomized trial to test a tailored educational intervention on the sleep-related safety behaviors of teen mothers. In one study arm, the intervention will include not only the teen mothers but also senior caregivers (SCGs) to assess the influence they have in the decision-making of young mothers regarding infant health and safety. Our hypotheses are H1) teen mothers exposed to intervention will be more likely than controls to adopt safe sleep practices, and H2) teen mothers will be more likely to use those practices when they and their mothers or other significant female senior caregivers also participate in safe sleep education. Better understanding of the mediating role of female SCGs in the health decision of young mothers for their children may have implications for interventions addressing important health problems.
RESUMO
Firearms contribute substantially to leading causes of death among US children ages 10-19 (suicide and homicide). Safe storage of guns is important but poorly adopted. This study sought to understand knowledge, attitudes, beliefs, and firearm storage practices among parents living in households with firearms. Focus groups (FG) were conducted with gun-owning parents/guardians in three US states with high firearm ownership. Participants also completed an anonymous survey which included demographic characteristics, previous gun education, purpose of gun ownership, and storage practices. Eight FG were conducted with 57 parents. 74% of participants stored at least one firearm unlocked, with many loaded. Overall risk perception for firearm injury was low. Many participants believed modeling responsible use within the family would demystify the presence of a firearm and decrease accidental shootings. There was strong perception that safe storage interferes with personal protection needs, especially for handguns. Trigger locks were considered a nuisance and rarely used. Parents were confident in their youth's ability to handle guns safely and did not believe that safe storage would deter suicide. Preferred messengers for safe storage education were military or law enforcement rather than physicians. Participants advocated for safe storage education paired with hands-on use education. Gun-owning parents supported safety education and endorsed education from nonmedical sources. Education about suicide prevention may improve adoption of safe storage by parents. These results will inform the development of a firearm safe storage campaign with improved acceptability for communities with high firearms use and ownership.

Mediation analysis was used to investigate the role of white matter integrity in the relationship between injury severity and verbal memory performance in participants with chronic pediatric traumatic brain injury (TBI). DTI tractography was used to measure fractional anisotropy (FA) within the corpus callosum, fornix, cingulum bundles, perforant pathways, and uncinate fasciculi. Injury severity was indexed using Glasgow Coma Scale (GCS) scores obtained at the time of the injury. Verbal memory was measured by performance on the long-delay free recall (LDFR) trial of the California Verbal Learning Test-Children's version. Participants were between the ages of 10-18 and included 21 children with TBI (injured before age 9) and 19 typically-developing children (TDC). Children with TBI showed lower FA across all pathways and poorer LDFR performance relative to TDC. Within the TBI group, mediation analysis revealed neither a significant total effect of GCS on LDFR nor significant direct effects of GCS on LDFR across pathways; however, the indirect effects of GCS on LDFR through FA of the corpus callosum, left perforant pathway, and left uncinate fasciculus were significant and opposite in sign to their respective direct effects. These results suggests that the predictive validity of GCS for LDFR is initially suppressed by the substantial variance accounted for by FA, which is uncorrelated with GCS, and the predictive validity of GCS increases only when FA is considered, and the opposing path is controlled. These findings illustrate the complex associations between acute injury severity, white matter pathways, and verbal memory several years following pediatric TBI.

INTRODUCTION: Sudden unexpected infant death is the leading cause of infant mortality with black: white infant mortality remaining at 2:1 for the last decade. Smartphone technology provides a convenient and accessible tool for injury prevention anticipatory guidance among at-risk communities. MATERIALS AND METHODS: A convenience sample of pregnant teen mothers who own a smartphone. During a 1-month postnatal home visit, a safe sleep environment survey was administered, infant sleep practices were observed, and mothers trained to take and submit standard infants' sleep environment photographs. Photographs were independently assessed for inter-rater reliability (IRR) across five sleep safety domains (primary outcome): sleep location, surface, position, presence of soft items, and hazards near the sleep area. Expert and novice coders IRR was measured using Cohen's kappa coefficient (K). Sleep safety correlation between photographs and observation, and parent report and observation was determined. RESULTS: Sixteen (57.1%) mothers completed the home visit. Most parents reported infants sleeping supine (78.5) in parents' bedroom (85.9%). Photographs demonstrated sleep position, soft items without the baby present, and hanging toys had perfect agreement across all three coder pairs. Safe sleep experts' IRR demonstrated perfect agreement for sleep location, position, and soft items. While 83.8% of parents were observed putting their infants down to sleep on their back, 78.5% of parents reported doing the same and 82.4% of the photographs demonstrated supine infant sleep position. CONCLUSION: Using photographs, coders can reliably categorize some key infant sleep safety aspects, and photograph sleep safety is comparable to parent report and direct observation.
RESUMO
INTRODUCTION: The growing interest in incorporating prevention into emergency health care make it timely to examine the use of computer technology to efficiently deliver effective education in this setting. STUDY DESIGN: This RCT compared results from an intervention group (n=367) that received child passenger safety information, to an attention-matched control (n=375). A baseline survey and two follow-up surveys at 3 and 6 months were conducted. SETTING/PARTICIPANTS: Data were collected from June 2014 to September 2016 from a sample of parents with children aged 4-7 years recruited from a pediatric emergency department in an East Coast urban area and one in a Midwest semi-rural area. INTERVENTION: A theory-based, stage-tailored educational program, Safety in Seconds v2.0TM, delivered on a mobile app. MAIN OUTCOME MEASURES: Four car seat behaviors: (1) having the correct restraint for the child's age and weight; (2) having the child ride in the backseat all the time; (3) buckling up the child all the time; and (4) having the child's restraint inspected by a child passenger safety technician. RESULTS: At 3 months, adjusting for baseline behaviors and attrition, the odds of reporting the correct behavior by the intervention group relative to the control group was 2.07 (p<0.01) for using the correct car seat; 2.37 (p<0.05) times for having the child ride in the back seat; 1.04 (nonsignificant) for riding buckled up all the time; and 1.99 (p<0.01) times for having the car seat inspected. At 6 months, there were statistically significant effects for reporting use of the correct car seat (OR=1.84, p<0.01) and having the car seat inspected (OR=1.73, p<0.01). CONCLUSIONS: Mobile apps hold promise for reaching large populations with individually tailored child passenger safety education. TRIAL REGISTRATION: Clinical Trial Registration # NCT02345941.

BACKGROUND: Sudden Unexpected Infant Death (SUID) results in 3400 sleep-related deaths yearly in the United States, yet caregivers' compliance with safe sleep recommendations remains less than optimal. Paternal caregiver's attitudes toward infant safe sleep messages are largely unaddressed, despite established differences between female and male caregiver perceptions. This study aimed to explore the determinants of safe sleep practices among male caregivers. METHODS: Focus groups were conducted in Arkansas with male caregivers of infants ages 2-12 months to discuss infant sleep routines, parental roles, sources for safe sleep information, and messaging suggestions for safe sleep promotion. The Health Belief Model of behavior change framed a moderator guide. Transcript-based analysis was used, and data were managed using HyperRESEARCH (version 2.8.3). The transcribed data were coded to identify significant themes. RESULTS: Ten focus groups were conducted with 46 participants. Inconsistent adherence to safe sleep practices was reported. Participants were more likely to describe safe location (57% of participants) and supine position behaviors (42%) than an uncluttered bed environment (26%). Caregivers acknowledged the importance of recommended safe sleep behavior, but admitted to unsafe practices, such as co-sleeping and unsafe daytime sleep. Lack of perceived risk, comfort, and/or resources, and disagreement among family members about safety practices were identified as barriers. Participants voiced concerns that current advertising portrays males as incompetent caregivers. Suggestions included portraying positive images of fathers and male caregivers acting to promote safety and the incorporation of statistics about the hazards of unsafe sleep to better engage fathers. Potential distribution venues included sporting events, home improvement and/or automotive stores, and social media from trusted sites (e.g. hospitals or medical professionals). CONCLUSIONS: Male caregivers demonstrate some knowledge base about infant sleep safety, but are not fully practicing all aspects of safe sleep. Targeted messaging towards male caregivers that includes factual information and statistics along with representing males in a positive light is desired.
RESUMO
BACKGROUND: Motor vehicle crashes are the leading cause of death for teens 14-19 years of age, with younger teen drivers at higher risk than older teens. Graduated driver licensing has been proven to reduce teen driver-related motor vehicle crashes and fatalities. Arkansas allows parents to request age waivers, which allow a teen to obtain a license for independent driving before the sixteenth birthday. The objectives of this study were to: (1) determine the prevalence of age waivers issued in Arkansas and (2) determine motor vehicle crash risks associated with 14 and 15 year old drivers. METHODS: This is a brief report on an informative query exploring risk factors related to age waivers. Publicly available databases were utilized for across state comparisons. The Web-based Injury Statistics Query and Reporting Systems (WISQARS) was utilized to calculate motor vehicle crash crude death rates. National Highway Traffic Safety Administration data were utilized to identify seat belt use rates. The Fatal Analysis Reporting System (FARS) was utilized to identify crash fatality risks for 14 and 15 year old drivers in Arkansas (N = 24). Age waiver data were obtained from the Arkansas Driver Control Administration. De-identified data on fatal crashes and rates of age waiver issuance in Arkansas for 14 and 15 year olds from 2004 through 2016 were calculated. RESULTS: We reviewed crash data for 14 and 15 year old drivers in Arkansas between 2004 and 2014 to determine fatality risks. Thirty-one out of seventy-five counties in Arkansas were above the state age waiver issuance rate of 30.4 per 1000 14 to 15 year old teens. Among the four states that had similar age waivers for 14 to 15 year olds, Arkansas had the highest motor vehicle death rate of 10.2 per 100,000 young teens and the lowest seat belt use rate at 73%. CONCLUSIONS: Arkansas had the highest reported teen crash fatality rates among 4 states with age waivers. The volume of age waivers issued in Arkansas is concerning. Further research is needed to understand parental motivation when asking for age waivers and their level of awareness of the risks involved.
RESUMO
BACKGROUND: Use of cranial CT scans in children has been increasing, in part due to increased awareness of sports-related concussions. CT is the largest contributor to medical radiation exposure, a risk factor for cancer. Long-term cancer risks of CT scans can be two to three times higher for children than for adults because children are more radiosensitive and have a longer lifetime in which to accumulate exposure from multiple scans. STUDY AIM: To compare the radiation exposure injured children receive when imaged at nonpediatric hospitals (NPHs) versus pediatric hospitals. METHODS: Injured children younger than 18 years who received a CT scan at a referring hospital during calendar years (CYs) 2010 and 2013 were included. Patient-level factors included demographics, mode of transportation, and Injury Severity Score, and hospital-level factors included region of state, radiology services, and hospital type and size. Our primary outcome of interest was the effective radiation dose. RESULTS: Four hundred eighty-seven children were transferred to the pediatric trauma center during CYs 2010 and 2013, with a median age of 7.2 years (interquartile range 5-13). The median effective radiation dose received at NPHs was twice that received at the pediatric trauma center (3.8 versus 1.6 mSv, P < .001). Results were confirmed in independent and paired analyses, after controlling for mode of transportation, emergency department disposition, level of injury severity, and at the NPH trauma center level, hospital type, size, region, and radiology services location. CONCLUSION: NPHs have the potential to substantially reduce the medical radiation received by injured children. Pediatric CT protocols should be considered.

OBJECTIVES: All-terrain vehicle (ATV) crashes have been responsible for significant injuries among children, despite public education efforts. Our study examined pediatric ATV injury patterns in US emergency departments (EDs) compared with injuries after motor vehicle crash (MVC) and sports activities. METHODS: We studied 2006 to 2011 data from the Nationwide Emergency Department Sample. Children younger than 18 years and involved in ATV crashes, MVC, or sports activities were included. The primary outcome analyzed was a constructed binary measure identifying severe trauma, defined as injury severity score greater than 15. Logistic regression models were fit to determine the association between mechanism of injury and severe trauma. RESULTS: A total of 6,004,953 ED visits were identified. Of these, ATV crashes accounted for 3.4%, MVC accounted for 44.7%, and sports activities accounted for 51.9%. Emergency department visits after ATV crashes were more likely to result in admission (8%) and incur higher median charges ($1263) compared with visits after sports activities (1%, $1013). Visits after sports activities were 90% less likely to result in severe trauma when compared with ATV crash visits. Emergency department visits after ATV crashes result in severe injuries similar to those sustained in MVC (odds ratio, 1.03; P = 0.626). CONCLUSIONS: Pediatric ED visits after ATV crashes result in significant injuries and charges. Public health interventions such as education, legislation, and engineering are needed to reduce injuries among children and the subsequent ED visits for care. The impact of proven interventions may be greatest for children living in rural areas and among older children, 10 to 17 years old.

BACKGROUND: Current American Academy of Pediatrics recommendations regarding transition from child safety/booster seat to adult safety belt use indicate that children should be at least 4 feet 9 inches, 8 years old, or 80 pounds. Proper fit in the vehicle seat, assessed with a five-point fit test, should also be met. Although most children reach 4 feet 9 inches around age 8 years, each child and vehicle presents a unique combination; thus a child may not fit appropriately in all vehicle types using only the 4 feet 9 inches requirement. METHODS: We enrolled children, aged 7 years to 12 years, into our study. Height, weight, and demographic data were obtained. A Child Passenger Safety Technician then performed the five-point fit test in each of a uniform lineup of five vehicles. Data were collected on fit in the standard vehicle seat and also in a booster seat. We set 90% as the threshold proportion of children who meet all criteria for proper fit to validate current recommendations of a height of 4 feet 9 inches. RESULTS: Data were collected on 388 children. The percentage of 90% proper fit was met in the compact car and small sport-utility vehicle (SUV). However, only 80 (77%) of 104 students (p < 0.0001) that were 4 feet 9 inches or higher fit properly in the large SUV, only 87 (83%) of 105 students (p = 0.02) fit properly in the pickup truck, and only 91 (89%) of 102 students (p = 0.74) fit properly in the minivan. CONCLUSION: Substantial proportions of children meeting current height guidelines for an adult seat belt do not meet safety requirements for fit, especially in larger, commonly used vehicles (large SUVs and trucks). This emphasizes the need for evaluation of fit by a trained personnel and/or development of standard back seat dimensions in all vehicles for maximum safety. LEVEL OF EVIDENCE: Epidemiologic level 1.
