BACKGROUND: Despite reductions in youth pedestrian and bicyclist deaths over the past two decades, these injuries remain a substantial cause of morbidity and mortality for children and adolescents. There is a need for additional information on non-fatal pediatric pedestrian injuries and the role of traumatic brain injury (TBI), a leading cause of acquired disability. METHODS: Using a multi-year national sample of emergency department (ED) records, we estimated annual motorized-vehicle related pediatric pedestrian and bicyclist (i.e. pedalcyclist) injury rates by age and region. We modeled in-hospital fatality risk controlling for age, gender, injury severity, TBI, and trauma center status. RESULTS: ED visits for pediatric pedestrian injuries declined 19.3% (95% CI 16.8, 21.8) from 2006 to 2012, with the largest decreases in 5-to-9 year olds and 10-to-14 year olds. Case fatality rates also declined 14.0%. There was no significant change in bicyclist injury rates. TBI was implicated in 6.7% (95% CI 6.3, 7.1) of all pedestrian and bicyclist injuries and 55.5% (95% CI 27.9, 83.1) of fatalities. Pedestrian ED visits were more likely to be fatal than bicyclist injuries (aOR = 2.4, 95% CI 2.3, 2.6), with significant additive interaction between pedestrian status and TBI. CONCLUSIONS: TBI in young pedestrian ED patients was associated with a higher risk of mortality compared to cyclists. There is a role for concurrent clinical focus on TBI recovery alongside ongoing efforts to mitigate and prevent motor vehicle crashes with pedestrians and bicyclists. Differences between youth pedestrian and cycling injury trends merit further exploration and localized analyses, with respect to behavior patterns and interventions. ED data captures a substantially larger number of pediatric pedestrian injuries compared to crash reports and can play a role in those analyses.

OBJECTIVE:This study evaluated the impact of an integrated behavioral health home (BHH) pilot on adults with psychotic and bipolar disorders. METHODS:Quasi-experimental methods were used to compare outcomes before (September 2014-August 2015) and after the intervention (September 2015-August 2016) among ambulatory BHH patients and a control group. Electronic health records were compared between 424 BHH patients (N=369, psychotic disorder; N=55, bipolar disorder) and 1,521 individuals from the same urban, safety-net health system who were not enrolled in the BHH. Groups were weighted by propensity score on the basis of sex, age, race-ethnicity, language, 2010 U.S. Census block group characteristics, Medicare and Medicaid enrollment, and diabetes diagnosis. RESULTS:BHH patients had fewer total psychiatric hospitalizations and fewer total emergency visits compared with the control group, a difference that was predominantly driven by patients with at least one psychiatric hospitalization or ED visit. There were no differences in medical hospitalizations. Although BHH patients were more likely to receive HbA1c screening, there were no differences between the groups in lipid monitoring. Regarding secondary outcomes, there were no significant differences in changes in metabolic monitoring parameters among patients with diabetes. CONCLUSIONS:Participation in a pilot ambulatory BHH program among patients with psychotic and bipolar disorders was associated with significant reductions in ED visits and psychiatric hospitalizations and increased HbA1c monitoring. This evaluation builds on prior research by specifying intervention details and the clinical target population, strengthening the evidence base for care integration to support further program dissemination.

BACKGROUND: Amphetamine is the most prevalent prescription stimulant in the United States, both medically and nonmedically. Reliable data on nonmedical use is needed to continue to inform prevention. To determine whether adolescents accurately self-report nonmedical amphetamine use, we compared self-reports of nonmedical amphetamine use and nonmedical Adderall use in a national sample. METHODS: We examined self-reported nonmedical Adderall and amphetamine use in a nationally representative sample of 24,740 high school seniors in the Monitoring the Future study (2010-2015). We examined prevalence and correlates of discordant responses among past-year Adderall users, defined as reporting past-year nonmedical Adderall use, but not reporting past-year nonmedical amphetamine use. RESULTS: While 6.9% reported nonmedical Adderall use and 7.9% reported nonmedical amphetamine use, over a quarter (28.7%) of Adderall users reported no amphetamine use. Those at highest risk for Adderall use tended to be at lower odds of providing a discordant response. Older students (aged >/=18), black students, and those with parents of lower educational attainment were more likely to report no amphetamine use, despite reporting Adderall use. Lifetime use of various drugs was associated with decreased odds of providing a discordant response; however, only nonmedical opioid use was associated with significant decreased odds in multivariable models. Disapproval towards amphetamine use increased odds of providing a discordant response, while higher exposure to users decreased odds of providing a discordant response. CONCLUSION: Prevalence of nonmedical amphetamine use may be underreported on some surveys, particularly among specific subpopulations. Future surveys must ensure accurate and consistent responses.

Children who grow up in poverty are more likely to experience chronic stressors that generate "wear" on stress regulatory systems including the hypothalamus-pituitary-adrenal (HPA) axis. This can have long-term consequences for health and well-being. Prior research has examined the role of proximal family and home contributions to HPA axis functioning. However, there is evidence to suggest that more distal levels of context, including neighborhoods, also matter. Prior evidence has primarily focused on adolescents and adults, with little evidence linking the neighborhood context with HPA activity in infancy and toddlerhood. We tested whether neighborhood disadvantage (indexed by US Census data) was associated with basal salivary cortisol levels at 7, 15, and 24 months of child age in a large sample of families (N = 1,292) residing in predominately low-income and rural communities in the United States. Multilevel models indicated that neighborhood disadvantage was positively associated with salivary cortisol levels and that this effect emerged across time. This effect was moderated by the race/ethnicity of children such that the association was only observed in White children in our sample. Findings provide preliminary evidence that the neighborhood context is associated with stress regulation during toddlerhood, elucidating a need for future work to address possible mechanisms.

OBJECTIVE:To assess needs perceptions regarding the importance of and satisfaction with psychosocial support among cancer patients and survivors in Puerto Rico. METHODS:A cross-sectional study was conducted in 181 participants (70 men and 111 women) who were either undergoing cancer treatment (patients) or had completed cancer treatment (survivors). Participants completed a sociodemographic and clinical characteristics questionnaire, and the Psychosocial Needs Inventory (PNI). RESULTS:The participants reported having or having had prostate (36%) or breast (32%) cancer or some other cancer type (32%). Of the 149 participants reporting cancer type, 130 were classified as having a high perceived level of health and quality of life, and 19 were classified as having a low perceived level of health and quality of life. In terms of perceived needs, the highest level of importance were assigned to the Support Network (e.g. family, friends, neighbors, care professionals; M = 2.88, SD = 0.43) and Health Professional (e.g., patient-health professional relationship, etc.; M = 2.80, SD = 0.50) categories, and the Emotional and Spiritual category was given the lowest importance (e.g., help managing negative emotions and spiritual counseling, etc.; M = 2.62, SD = 0.66). These perceptions varied by gender, perceived health status, and date of diagnosis. Women assigned more importance to the Health Professional and Information categories. CONCLUSION/CONCLUSIONS:The results reflect the importance of considering psychosocial needs when providing psychosocial support to cancer patients and survivors. These findings are anticipated to inform services provided by psychosocial oncology support programs in Puerto Rico.

The objective of this study was to examine the association between financial hardship, condomless anal intercourse and HIV risk among a sample of men who have sex with men (MSM). Users of a popular geosocial networking application in Paris were shown an advertisement with text encouraging them to complete a anonymous web-based survey (n = 580). In adjusted multivariate models, high financial hardship (compared to low financial hardship) was associated with engagement in condomless anal intercourse (aRR 1.28; 95% CI 1.08-1.52), engagement in condomless receptive anal intercourse (aRR 1.34; 95% CI 1.07-1.67), engagement in condomless insertive anal intercourse (aRR 1.30; 95% CI 1.01-1.67), engagement in transactional sex (aRR 2.36; 95% CI 1.47-3.79) and infection with non-HIV STIs (aRR 1.50; 95% CI 1.07-2.10). This study suggests that interventions to reduce financial hardships (e.g., income-based strategies to ensure meeting of basic necessities) could decrease sexual risk behaviors in MSM.

BACKGROUND:The Food and Drug Administration's 2004 antidepressant warning was followed by decreases in antidepressant prescribing for youth. This was due to declines in all types of depression treatment, not just the intended changes in antidepressant prescribing patterns. Little is known about how these patterns varied by race/ethnicity. METHOD:Data are Medicaid claims from four U.S. states (2002-2009) for youth ages 5-17. Interrupted time series analyses measured changes due to the warning in levels and trends, by race/ethnicity, of three outcomes: antidepressant prescription fills, depression treatment visits, and incident fluoxetine prescription fills. RESULTS:Prewarning, antidepressant fills were increasing across all racial/ethnic groups, fastest for White youth. Postwarning, there was an immediate drop and continued decline in the rate of fills among White youth, more than double the decline in the rate among Black and Latino youth. Prewarning, depression treatment visits were increasing for White and Latino youth. Postwarning, depression treatment stabilized among Latinos, but declined among White youth. Prewarning, incident fluoxetine fills were increasing for all groups. Postwarning, immediate increases and increasing trends of fluoxetine fills were identified for all groups. CONCLUSIONS:Antidepressant prescription fills declined most postwarning for White youth, suggesting that risk information may have diffused less rapidly to prescribers or caregivers of minorities. Decreases in depression treatment visits help to explain the declines in antidepressant prescribing and were largest for White youth. An increase in incident fluoxetine fills, the only medication indicated for pediatric depression at the time, suggests that the warning may have shifted prescribing practices.

Background: The relation between breastfeeding and early motor development is difficult to characterize because of the problems in existing studies such as incomplete control for confounding, retrospective assessment of infant feeding, and even the assessment of some motor skills too early.Objective: We sought to estimate associations between infant feeding and time to achieve major motor milestones in a US cohort.Design: The Upstate New York Infant Development Screening Program (Upstate KIDS Study) enrolled mothers who delivered live births in New York (2008-2010). Mothers of 4270 infants (boys: 51.7%) reported infant motor development at 4, 8, 12, 18, and 24 mo postpartum; information on infant feeding was reported at 4 mo. Accelerated failure time models were used to compare times to standing or walking across feeding categories while adjusting for parental characteristics, daycare, region, and infant plurality, sex, rapid weight gain, and baseline neurodevelopmental test results. Main models were stratified by preterm birth status.Results: The prevalence of exclusive breastfeeding in preterm infants was lower than in term infants at 4 mo postpartum (8% compared with 19%). After adjustment for confounders, term infants who were fed solids in addition to breast milk at 4 mo postpartum achieved both standing [acceleration factor (AF): 0.93; 95% CI: 0.87, 0.99] and walking (AF: 0.93; 95% CI: 0.88, 0.98) 7% faster than did infants who were exclusively breastfed, but these findings did not remain statistically significant after correction for multiple testing. We did not identify feeding-associated differences in motor milestone achievement in preterm infants.Conclusion: Our results suggest that differences in feeding likely do not translate into large changes in motor development. The Upstate KIDS Study was registered at clinicaltrials.gov as NCT03106493.

CONTEXT: Ventricular assist devices (VADs) improve quality of life in advanced heart failure (HF) patients, but there are little data exploring psychological symptoms in this population. OBJECTIVE: This study examined the prevalence of psychiatric symptoms and disease over time in VAD patients. METHODS: This prospective multicenter cohort study enrolled patients immediately before or after VAD implant and followed them up to forty-eight weeks. Depression and anxiety were assessed with PROMIS SF8a questionnaires. The panic disorder, acute stress disorder (ASD) and post-traumatic stress disorder (PTSD) modules of the Structured Clinical Interview for the DSM were used. RESULTS: Eighty-seven patients were enrolled. Post-implant, depression and anxiety scores decreased significantly over time (p=0.03 and p<0.001 respectively). Two patients met criteria for panic disorder early after implantation but symptoms resolved over time. None met criteria for ASD or PTSD. CONCLUSIONS: Our study suggests VADs do not cause serious psychological harms and may have a positive impact on depression and anxiety. Furthermore, VADs did not induce PTSD, panic disorder or ASD in this cohort.
