Childhood Cardiovascular Risk Factors and Adult Cardiovascular Events.

BACKGROUND: Childhood cardiovascular risk factors predict subclinical adult cardiovascular disease, but links to clinical events are unclear. METHODS: In a prospective cohort study involving participants in the International Childhood Cardiovascular Cohort (i3C) Consortium, we evaluated whether childhood risk factors (at the ages of 3 to 19 years) were associated with cardiovascular events in adulthood after a mean follow-up of 35 years. Body-mass index, systolic blood pressure, total cholesterol level, triglyceride level, and youth smoking were analyzed with the use of i3C-derived age- and sex-specific z scores and with a combined-risk z score that was calculated as the unweighted mean of the five risk z scores. An algebraically comparable adult combined-risk z score (before any cardiovascular event) was analyzed jointly with the childhood risk factors. Study outcomes were fatal cardiovascular events and fatal or nonfatal cardiovascular events, and analyses were performed after multiple imputation with the use of proportional-hazards regression. RESULTS: In the analysis of 319 fatal cardiovascular events that occurred among 38,589 participants (49.7% male and 15.0% Black; mean [±SD] age at childhood visits, 11.8±3.1 years), the hazard ratios for a fatal cardiovascular event in adulthood ranged from 1.30 (95% confidence interval [CI], 1.14 to 1.47) per unit increase in the z score for total cholesterol level to 1.61 (95% CI, 1.21 to 2.13) for youth smoking (yes vs. no). The hazard ratio for a fatal cardiovascular event with respect to the combined-risk z score was 2.71 (95% CI, 2.23 to 3.29) per unit increase. The hazard ratios and their 95% confidence intervals in the analyses of fatal cardiovascular events were similar to those in the analyses of 779 fatal or nonfatal cardiovascular events that occurred among 20,656 participants who could be evaluated for this outcome. In the analysis of 115 fatal cardiovascular events that occurred in a subgroup of 13,401 participants (31.0±5.6 years of age at the adult measurement) who had data on adult risk factors, the adjusted hazard ratio with respect to the childhood combined-risk z score was 3.54 (95% CI, 2.57 to 4.87) per unit increase, and the mutually adjusted hazard ratio with respect to the change in the combined-risk z score from childhood to adulthood was 2.88 (95% CI, 2.06 to 4.05) per unit increase. The results were similar in the analysis of 524 fatal or nonfatal cardiovascular events. CONCLUSIONS: In this prospective cohort study, childhood risk factors and the change in the combined-risk z score between childhood and adulthood were associated with cardiovascular events in midlife.

Happy Family, Healthy Kids: A Healthy Eating and Stress Management Program in Low-Income Parent-Preschooler Dyads.

BACKGROUND: Substantial effort has been invested to combat childhood obesity, but overall effects are disappointing, especially in low-income racial minority children. One possible reason is a lack of focus on the important stress-eating connection. Stress can negatively influence eating behaviors, leading to an increased appetite for high-fat and energy-dense foods. OBJECTIVE: This study aimed to evaluate the preliminary effects of a healthy eating and stress management program targeting multiple theoretical variables on improving eating behavior (dyads' fruit/vegetable intake, emotional eating), food insecurity, anthropometric characteristics (dyads' body mass index, % body fat), cardiovascular health (dyads' blood pressure), and mental well-being (parental stress). METHODS: A one-group, quasi-experimental pilot study was conducted among 107 low-income parent-preschooler dyads. The 14-week program included a parent component, a parent-preschooler learning component, and a day care-based preschooler component. RESULTS: The program had positive effects on improving dyads' fruit/vegetable intake, food insecurity, body mass index, and blood pressure and parents' nutrition knowledge, self-efficacy, support, food resource management behavior, problem-focused coping, and home eating environment. The overall satisfaction rate was 95.2%, and 88.1% stated that the program assisted their families with having a healthy lifestyle. DISCUSSION: Results support the preliminary effects of the program on improving health outcomes in rural and urban low-income families. Although warranting further investigation with a more rigorous randomized controlled trial, the healthy eating and stress management program provides a potential solution to the current coexistence of an obesity epidemic and mental health crisis.

Association between parental education level & outcomes for children with long-term ventilator dependence: Communication behaviors as moderating variables.

PURPOSE: The purpose of this study was to examine the correlation between parental education level and outcomes for children with long-term ventilator dependence (LTVD) and their families and whether parent communication behaviors with hospital nurses moderated the relationship. Advances in medical technology and policy changes allow children with LTVD to be cared for at home. The child's diagnosis and disease severity affect their health outcomes, as do their family's social determinants of health (SDoH) such as parent education. DESIGN AND METHODS: This secondary data analysis used chi-square tests to evaluate the correlation between parental education level and outcomes. Generalized linear mixed effect models were used to examine the moderation effect of parent communication behaviors. RESULTS: Lower parental education level was associated with more child respiratory infections and more parental uncertainty within one month following hospital discharge. Lower parent education level was also associated with fewer unplanned contacts with providers within one week post-discharge. Additionally, parent use of Verifying Understanding communication behaviors moderated the relationship between parental education level and number of respiratory infections and amount of parental uncertainty. Finally, parent use of Negotiating Roles moderated the association between education level and number of unplanned visits. CONCLUSIONS: Contradicting previous research, lower parental education level does not consistently correspond to adverse outcomes and may be explained by parents' determination to ensure optimal outcomes for their children with LTVD. PRACTICE IMPLICATIONS: Overall, healthcare providers should not be concerned that children with LTVD will have different outcomes based on their parents' education level.

Automated, machine learning-based alerts increase epilepsy surgery referrals: A randomized controlled trial.

OBJECTIVE: To determine whether automated, electronic alerts increased referrals for epilepsy surgery. METHODS: We conducted a prospective, randomized controlled trial of a natural language processing-based clinical decision support system embedded in the electronic health record (EHR) at 14 pediatric neurology outpatient clinic sites. Children with epilepsy and at least two prior neurology visits were screened by the system prior to their scheduled visit. Patients classified as a potential surgical candidate were randomized 2:1 for their provider to receive an alert or standard of care (no alert). The primary outcome was referral for a neurosurgical evaluation. The likelihood of referral was estimated using a Cox proportional hazards regression model. RESULTS: Between April 2017 and April 2019, at total of 4858 children were screened by the system, and 284 (5.8%) were identified as potential surgical candidates. Two hundred four patients received an alert, and 96 patients received standard care. Median follow-up time was 24 months (range: 12-36 months). Compared to the control group, patients whose provider received an alert were more likely to be referred for a presurgical evaluation (3.1% vs 9.8%; adjusted hazard ratio [HR] = 3.21, 95% confidence interval [CI]: 0.95-10.8; one-sided p = .03). Nine patients (4.4%) in the alert group underwent epilepsy surgery, compared to none (0%) in the control group (one-sided p = .03). SIGNIFICANCE: Machine learning-based automated alerts may improve the utilization of referrals for epilepsy surgery evaluations.

Findings from a Randomized Controlled Trial of SMART: An EHealth Intervention for Mild Traumatic Brain Injury.

OBJECTIVE: The aim of this study was to examine the efficacy of the SMART (Self-Management After Recent Traumatic brain injury) program and potential moderators. METHODS: Parallel randomized controlled trial (ClinicalTrials.gov Identifier: NCT03498495) was conducted. Eligibility criteria included treatment for mild traumatic brain injury in the emergency department and age 11-18 years. Participants were assigned equally to SMART (n = 35) or usual care (UC; n = 36). SMART included symptom monitoring and online modules supporting the return to activities and symptom management. Coping and quality of life (QoL) (primary outcomes) and post-concussive symptoms (secondary outcome) were assessed at baseline and weekly for 4 weeks. RESULTS: Groups did not differ in coping, QoL, or return to pre-injury symptom levels at any time point. Problem-focused engagement (PFE) moderated group differences over time (p = .02). At high PFE, UC participants reported lower QoL at time 1 (effect size [ES] = 0.60); SMART participants did not report a decline at any point. At low PFE, SMART participants reported declining QoL from pre-injury to time 1 (ES = 0.68), whereas UC participants reported an increase from time 1 to 3 (ES = 0.56). PFE also moderated group differences on the Health and Behavior Inventory (HBI) cognitive (p = .02) and somatic symptom scales (p = .05). At high PFE, SMART participants reported a more rapid return to pre-injury levels than UC participants (p = .05). Resilience also moderated group differences in QoL and HBI cognitive recovery. CONCLUSION: Effectiveness of the SMART app varied based on preinjury coping styles and resilience, underscoring the potential need to tailor treatments to individual characteristics.

Heterogeneity in Neutrophil Extracellular Traps from Healthy Human Subjects.

Neutrophil extracellular traps (NETs), a key component of early defense against microbial infection, are also associated with tissue injury. NET composition has been reported to vary with some disease states, but the composition and variability of NETs across many healthy subjects provide a critical comparison that has not been well investigated. We evaluated NETs from twelve healthy subjects of varying ages isolated from multiple blood draws over a three-and-one-half-year period to delineate the variability in extracellular DNA, protein, enzymatic activities, and susceptibility to protease inhibitors. We calculated correlations for NET constituents and loss of human bronchial epithelial barrier integrity, measured by transepithelial electrical resistance, after NET exposure. We found that although there was some variability within the same subject over time, the mean NET total DNA, dsDNA, protein, LDH, neutrophil elastase (NE), and proteinase 3 (PR3) in isolated NETs were consistent across subjects. NET serine protease activity varied considerably within the same donor from day to day. The mean NET cathepsin G and MPO were significantly different across donors. IL-8 > IL-1RA > G-CSF were the most abundant cytokines in NETs. There was no significant difference in the mean concentration or variability of IL-8, IL-1RA, G-CSF, IL-1α, IL-1ß, or TNF-α in different subjects' NETs. NET DNA concentration was correlated with increased NET neutrophil elastase activity and higher NET IL-1RA concentrations. The mean reduction in protease activity by protease inhibitors was significantly different across donors. NET DNA concentration correlated best with reductions in the barrier integrity of human bronchial epithelia. Defining NET concentration by DNA content correlates with other NET components and reductions in NET-driven epithelial barrier dysfunction, suggesting DNA is a reasonable surrogate measurement for these complex structures in healthy subjects.

Parent- and Adolescent-reported Executive Functioning in the Context of Randomized Controlled Trials of Online Family Problem-Solving Therapy.

OBJECTIVE: We examined parent- and adolescent-reported executive functioning (EF) behaviors following pediatric traumatic brain injury (TBI) in the context of Online Family Problem-Solving Therapy (OFPST) and moderators of change in EF behaviors. METHOD: In total, 274 families were randomized to OFPST or an internet resource comparison group. Parents and adolescents completed the Behavior Rating Inventory of Executive Function at four time points. Mixed models were used to examine EF behaviors, assessing the effects of visit, treatment group, rater, TBI severity, age, socioeconomic status, and family functioning. RESULTS: Parents rated their adolescents' EF as poorer (F(3,1156) = 220.15, p < .001; M = 58.11, SE = 0.73) than adolescents rated themselves (M = 51.81, SE = 0.73). Across raters, EF behaviors were poorer for adolescents whose parents had less education (F(3,1156) = 8.60, p = .003; M = 56.76, SE = 0.98) than for those with more education (M = 53.16, SE = 0.88). Age at baseline interacted with visit (F(3,1156) = 5.05, p = .002), such that families of older adolescents reported improvement in EF behaviors over time. Family functioning also interacted with visit (F(3, 1156) = 2.61, p = .049), indicating more improvement in EF behaviors over time in higher functioning families. There were no effects of treatment or TBI severity. CONCLUSION: We identified a discrepancy between parent- and adolescent-reported EF, suggesting reduced awareness of deficits in adolescents with TBI. We also found that poorer family functioning and younger age were associated with poorer recovery after TBI, whereas adolescents of parents with less education were reported as having greater EF deficits across time points.

Seizures and Cognitive Outcome After Traumatic Brain Injury: A Post Hoc Analysis.

INTRODUCTION: Seizures and abnormal periodic or rhythmic patterns are observed on continuous electroencephalography monitoring (cEEG) in up to half of patients hospitalized with moderate to severe traumatic brain injury (TBI). We aimed to determine the impact of seizures and abnormal periodic or rhythmic patterns on cognitive outcome 3 months following moderate to severe TBI. METHODS: This was a post hoc analysis of the multicenter randomized controlled phase 2 INTREPID2566 clinical trial conducted from 2010 to 2016 across 20 United States Level I trauma centers. Patients with nonpenetrating TBI and postresuscitation Glasgow Coma Scale scores 4-12 were included. Bedside cEEG was initiated per protocol on admission to intensive care, and the burden of ictal-interictal continuum (IIC) patterns, including seizures, was quantified. A summary global cognition score at 3 months following injury was used as the primary outcome. RESULTS: 142 patients (age mean + / - standard deviation 32 + / - 13 years; 131 [92%] men) survived with a mean global cognition score of 81 + / - 15; nearly one third were considered to have poor functional outcome. 89 of 142 (63%) patients underwent cEEG, of whom 13 of 89 (15%) had severe IIC patterns. The quantitative burden of IIC patterns correlated inversely with the global cognition score (r = - 0.57; p = 0.04). In multiple variable analysis, the log-transformed burden of severe IIC patterns was independently associated with the global cognition score after controlling for demographics, premorbid estimated intelligence, injury severity, sedatives, and antiepileptic drugs (odds ratio 0.73, 95% confidence interval 0.60-0.88; p = 0.002). CONCLUSIONS: The burden of seizures and abnormal periodic or rhythmic patterns was independently associated with worse cognition at 3 months following TBI. Their impact on longer-term cognitive endpoints and the potential benefits of seizure detection and treatment in this population warrant prospective study.

The impact of short sleep on food reward processes in adolescents.

Short sleep has been linked to adolescent risk of obesity, but questions remain regarding the dietary mechanisms by which this occurs. We tested whether mildly shortening sleep influences how rewarding and appealing healthy adolescents find several kinds of foods. Eighty-eight healthy adolescents completed a within-subjects crossover sleep experiment comparing 5 days of Short Sleep (6.5 hr sleep opportunity) with 5 days of Healthy Sleep (9.5 hr sleep opportunity). Following each condition, adolescents completed measures of food appeal and reinforcing value of food across five food types: sweets/desserts, fruits/vegetables, lean meats/eggs, fast food and processed snacks. Adolescents averaged 2.2 hr/night longer sleep periods in Healthy Sleep versus Short Sleep. We observed a significant interaction of experimental order with sleep condition on three of four primary outcomes related to the appeal and reinforcing value of foods (p's < .005). When Short Sleep preceded Healthy Sleep, adolescents endorsed significantly greater appeal (p < .04) and rewarding value of food (p's ranging from <.01 to .048) during Short Sleep (compared to Healthy Sleep). However, when Healthy Sleep preceded Short Sleep, we did not observe a main effect of sleep condition on the same outcomes (p's > .05). This study provides evidence that restricting adolescents' sleep opportunity to 6.5 hr (compared to sleeping a healthy amount) increases the appeal and reinforcing value of a variety of foods, but this may occur only under protracted short sleep. Increased food reward may be one mechanism linking chronically shortened sleep with risk of obesity in adolescence.

Ecological and Syndemic Predictors of Drug Use During Sex and Transactional Sex among U.S. Black Men Who Have Sex with Men: A Secondary Data Analysis from the HPTN 061 Study.

Threats to sexual health among U.S. Black men who have sex with men (MSM) may manifest in a context of social adverse experiences. Situational sex is one such context, which we characterize as sexual behaviors driven either by a desire to cultivate a specific sexual experience or attributable to social vulnerability. Two characterizations of situational sex explored in this study were drug use during sex and transactional sex. Guided by ecological and syndemic frameworks, we conducted a secondary data analysis of social conditions and sexual behaviors among a prospective cohort of Black MSM from the HIV Prevention Trial Network (HPTN) 061 study. Using structural equation modeling, this analysis examined the indirect effect of syndemic factors (substance use, depression, violence exposure) in the relationship between ecological constructs (anti-Black/homophobic stigma, childhood violence, and economic vulnerability) and situational sex (drug use during sex, transactional sex). Model fit indices, CFI (.870) and SRMR (.091), demonstrated reasonable fit. Significant indirect effects emerged via substance use for economic vulnerability (indirect effect = .181, 95% CI [.078, .294]) and anti-Black/homophobic violence and stigma (indirect effect = .061, 95% CI [.008, .121]) on drug use during sex; as well as on transactional sex (economic vulnerability indirect effect = .059, 95% CI [.018, .121] and anti-Black/homophobic stigma and violence indirect effect = .020, 95% CI [.003, .051]). Findings implicate the need for social and fiscal intervention to address upstream, ecological, and syndemic factors that influence inherent vulnerability of situational sex and overall threats to sexual health among Black MSM.

Screen time use impacts low-income preschool children's sleep quality, tiredness, and ability to fall asleep.

BACKGROUND: Sleep is increasingly recognized as a vital part of health. Screen time has been linked to sleep quality in children. The purpose of this study was to analyze associations between screen time and sleep characteristics among low-income preschoolers. METHODS: A total of 1,700 preschool-aged children participated in this study at 50 federally and state-funded preschool centers in Michigan. Baseline measurement for an ongoing longitudinal intervention trial was obtained for cross-sectional use. At baseline, parents reported the number of hours their child spent engaging in screen time on a typical week day and weekend. An aggregate measure of total screen time was created. Parents reported on the quality of their child's sleep, how often they were tired during the day, and whether they had difficulty falling asleep. A mixed model linear regression was created to analyze data. RESULTS: Controlling for child's age, race, and parental income, children who engaged in more screen time were significantly more likely to have more trouble falling or staying asleep, be tired during the day, and had worse quality of sleep (P values = .004, .006 and .001, respectively). Spearman correlations of screen time, sleep variables and demographics show parents of Black children reported significantly higher weekly screen time than parents of non-Black children (r = 0.23, P < .001) and that tiredness was associated with Black race (r = 0.15, P < .001), Hispanic/Latino ethnicity (r = -0.14, P < .001), and parental education (r = 0.06, P = .016). CONCLUSION: This report confirms prior associations between screen time and sleep reported in other pediatric populations. Further research is needed to confirm these results in other populations using more rigorous measures of screen time, sleep, and physical activity, as well as longitudinal assessments. Despite these limitations, findings suggest that interventions to help parents limit children's screen time and impact their sleep health merit investigation.

Prediction of adult class II/III obesity from childhood BMI: the i3C consortium.

BACKGROUND AND OBJECTIVES: Adult class II/III obesity (BMI ≥ 35 kg/m2) has significant adverse health outcomes. Early prevention and treatment are critical, but prospective childhood risk estimates are lacking. This study aimed to define the prospective risk of adult class II/III obesity, using childhood BMI. METHODS: Children ages 3-19 years enrolled in cohorts of the International Childhood Cardiovascular Cohort (i3C) consortium with measured BMI assessments in childhood and adulthood were included. Prospective risk of adult class II/III obesity was modeled based on childhood age, sex, race, and BMI. RESULTS: A total of 12,142 individuals (44% male, 85% white) were assessed at median age 14 [Interquartile range, IQR: 11, 16] and 33 [28, 39] years. Class II/III adult obesity developed in 6% of children with normal weight; 29% of children with overweight; 56% of children with obesity; and 80% of children with severe obesity. However, 38% of the 1440 adults with class II/III obesity (553/1440) were normal weight as children. Prospective risk of adult class II/III obesity varied by age, sex, and race within childhood weight status classifications, and is notably higher for girls, black participants, and those in the United States. The risk of class II/III obesity increased with older adult age. CONCLUSIONS: Children with obesity or severe obesity have a substantial risk of adult class II/III obesity, and observed prospective risk estimates are now presented by age, sex, race, and childhood BMI. Clinical monitoring of children's BMI for adult class II/III obesity risk may be especially important for females and black Americans.

Prospective validation of a machine learning model that uses provider notes to identify candidates for resective epilepsy surgery.

OBJECTIVE: Delay to resective epilepsy surgery results in avoidable disease burden and increased risk of mortality. The objective was to prospectively validate a natural language processing (NLP) application that uses provider notes to assign epilepsy surgery candidacy scores. METHODS: The application was trained on notes from (1) patients with a diagnosis of epilepsy and a history of resective epilepsy surgery and (2) patients who were seizure-free without surgery. The testing set included all patients with unknown surgical candidacy status and an upcoming neurology visit. Training and testing sets were updated weekly for 1 year. One- to three-word phrases contained in patients' notes were used as features. Patients prospectively identified by the application as candidates for surgery were manually reviewed by two epileptologists. Performance metrics were defined by comparing NLP-derived surgical candidacy scores with surgical candidacy status from expert chart review. RESULTS: The training set was updated weekly and included notes from a mean of 519 ± 67 patients. The area under the receiver operating characteristic curve (AUC) from 10-fold cross-validation was 0.90 ± 0.04 (range = 0.83-0.96) and improved by 0.002 per week (P < .001) as new patients were added to the training set. Of the 6395 patients who visited the neurology clinic, 4211 (67%) were evaluated by the model. The prospective AUC on this test set was 0.79 (95% confidence interval [CI] = 0.62-0.96). Using the optimal surgical candidacy score threshold, sensitivity was 0.80 (95% CI = 0.29-0.99), specificity was 0.77 (95% CI = 0.64-0.88), positive predictive value was 0.25 (95% CI = 0.07-0.52), and negative predictive value was 0.98 (95% CI = 0.87-1.00). The number needed to screen was 5.6. SIGNIFICANCE: An electronic health record-integrated NLP application can accurately assign surgical candidacy scores to patients in a clinical setting.

Dopamine-Related Genes Moderate the Association Between Family Environment and Executive Function Following Pediatric Traumatic Brain Injury: An Exploratory Study.

OBJECTIVE: This study examined whether carrying dopamine-related "risk" genes-either the dopamine transporter (DAT1) 10-repeat allele or dopamine receptor-4 (DRD4) 7-repeat allele-moderated the association of family environment and executive function (EF) following traumatic brain injury (TBI) in early childhood. METHODS: Caregivers of children with TBI or orthopedic injury (OI) completed the Behavior Rating Inventory of Executive Function (BRIEF) at postinjury visits. General linear models examined gene by environment interactions as moderators of the effects of TBI on EF at 12 months and 7 years postinjury. RESULTS: At 12 months, we did not find any significant gene by environment interactions. At 7 years, we found a significant 3-way interaction among combined carrier status, level of permissive parenting, and injury type. For children exposed to more optimal parenting, carriers of DAT1 and/or DRD4 risk alleles with TBI showed significantly worse parent-reported EF than carriers with OI. In those with less optimal parenting, carriers and noncarriers with TBI, as well as carriers with OI, showed significantly worse parent-reported EF than noncarriers with OI, with medium to large effect sizes. CONCLUSIONS: The findings highlight the importance of considering polygenetic and environmental factors in future studies of recovery following TBI and other injuries in childhood.

Behavior Problems Following Childhood TBI: The Role of Sex, Age, and Time Since Injury.

OBJECTIVE: To examine the frequency of behavioral problems after childhood traumatic brain injury (TBI) and their associations with injury severity, sex, and social environmental factors. SETTING: Children's hospitals in the Midwestern/Western United States. PARTICIPANTS: 381 boys and 210 girls with moderate (n = 359) and severe (n = 227) TBI, with an average age at injury of 11.7 years (range 0.3-18) who were injured ≤3 years ago. DESIGN: Secondary data analysis of a multistudy cohort. MAIN MEASURES: Child Behavior Checklist (CBCL) administered pretreatment. RESULTS: Thirty-seven percent had borderline/clinical elevations on the CBCL Total Problem Scale, with comparable rates of Internalizing and Externalizing problems (33% and 31%, respectively). Less parental education was associated with higher rates of internalizing, externalizing, and total problems. Time since injury had a linear association with internalizing symptoms, with greater symptoms at longer postinjury intervals. Younger boys had significantly higher levels of oppositional defiant symptoms than girls, whereas older girls had significantly greater attention-deficit hyperactivity disorder symptoms than boys. CONCLUSIONS: Pediatric TBI is associated with high rates of behavior problems, with lower socioeconomic status predicting substantially elevated risk. Associations of higher levels of internalizing symptoms with greater time since injury highlight the importance of tracking children over time.

Recovery Trajectories of Child and Family Outcomes Following Online Family Problem-Solving Therapy for Children and Adolescents after Traumatic Brain Injury.

OBJECTIVES: We conducted joint analyses from five randomized clinical trials (RCTs) of online family problem-solving therapy (OFPST) for children with traumatic brain injury (TBI) to identify child and parent outcomes most sensitive to OFPST and trajectories of recovery over time. METHODS: We examined data from 359 children with complicated mild to severe TBI, aged 5-18, randomized to OFPST or a control condition. Using profile analyses, we examined group differences on parent-reported child (internalizing and externalizing behavior problems, executive function behaviors, social competence) and family outcomes (parental depression, psychological distress, family functioning, parent-child conflict). RESULTS: We found a main effect for measure for both child and family outcomes [F(3, 731) = 7.35, p < .001; F(3, 532) = 4.79, p = .003, respectively], reflecting differing degrees of improvement across measures for both groups. Significant group-by-time interactions indicated that children and families in the OFPST group had fewer problems than controls at both 6 and 18 months post baseline [t(731) = -5.15, p < .001, and t(731) = -3.90, p = .002, respectively, for child outcomes; t(532) = -4.81, p < .001, and t(532) = -3.80, p < .001, respectively, for family outcomes]. CONCLUSIONS: The results suggest limited differences in the measures' responsiveness to treatment while highlighting OFPST's utility in improving both child behavior problems and parent/family functioning. Group differences were greatest at treatment completion and after extended time post treatment.

The epidemiology of HIV and other sexually transmitted infections in African, Caribbean and Black men in Toronto, Canada.

BACKGROUND: African, Caribbean, and Black (Black) men account for 16.5% of new HIV diagnoses among men in Ontario. There is substantial evidence that sexually transmitted infections (STIs) are associated with increased likelihood of HIV infection; however, little is known regarding the prevalence of HIV/STI co-infections among Black men in Toronto. Progress has been made in understanding factors contributing to racial/ethnic disparities in HIV between among men who have sex with men (MSM). In this study, we investigate within-racial group patterns of HIV/STI infection between Black MSM and Black men who only have sex with women (MSW). METHODS: A cross-sectional descriptive epidemiological study was conducted with a non-probability sample of Black men recruited from Toronto, Ontario. Audio Computer Assisted Self-Interviews (ACASI) surveys were used to collect demographic and behavioral data. Biological specimens were collected to screen for HIV and other STIs. Chi-Square tests were used to compare the prevalence of (1) HIV and current STIs between MSM and MSW and (2) current STIs between people living with HIV and people not living with HIV. Logistic regression models were constructed to assess whether or not history of STIs were associated with current HIV infection. RESULTS: The prevalence of HIV (9.2%), syphilis (7.2%), hepatitis B (2.7%), and high-risk anal HPV (8.4%) and penile HPV (21.3%) infections were high in Black men (N = 487) and were significantly increased in Black MSM compared with MSW; the prevalence of syphilis and high-risk HPV were also increased in men living with HIV. Men with a history of syphilis (OR = 6.48, 95% CI: 2.68,15.71), genital warts (OR = 4.32, 95% CI: 1.79,10.43) or genital ulcers (OR = 21.3, 95% CI: 1.89,239.51) had an increased odds of HIV infection. CONCLUSIONS: The HIV/STI prevalence was high among this sample of Black men, although the study design may have led to oversampling of men living with HIV. The associations between STIs and current HIV infection highlight the need for integrated of HIV/STI screening and treatment programs for Black men. Public health strategies are also needed to reduce disproportionate HIV/STI burden among Black MSM-including improving HPV vaccine coverage.

Emergency Department Care of Young Children at Risk for Traumatic Brain Injury: What Are We Doing and Do Parents Understand?

OBJECTIVES: The aims of the study were to describe emergency department (ED) management of young children with head injury and to assess parental comfort level and perceptions of ED care. METHODS: This was a prospective observational study of children younger than 5 years who presented to a pediatric ED after head injury. Children were eligible if clinical observation was an appropriate ED management option per the Pediatric Emergency Care Academic Research Network's neuroimaging clinical decision rule. Demographics, injury variables, and ED clinician surveys explaining the care provided were collected at time of study enrollment. Parents were subsequently contacted to assess understanding of ED management and comfort with care. RESULTS: One hundred four children were enrolled with a mean (standard deviation) age of 1.19 (1.34) years. Thirty (29%) had emergent neuroimaging and 59 (57%) were placed into a period of observation per clinician report. A total of 37 children received a head computed tomography, of which 21 (57%) were normal. Eighty-four parents (81%) completed the phone follow-up. Of these children, there was a significant difference between whether parents and clinicians reported that the child had been clinically observed in the ED (P < 0.0001). Parents of children who did not receive a head CT were more likely to be uncomfortable with the decision to obtain neuroimaging compared with those who did receive a head CT (P = 0.003). CONCLUSIONS: Parents are not always comfortable with the medical care practices provided and are often unaware of clinical observation when it does occur. Better parent-clinician communication could improve parental understanding and reduce overall discomfort.

Age-related changes in baroreflex sensitivity and cardiac autonomic tone in children mirrored by regional brain gray matter volume trajectories.

BackgroundThe baroreflex and central autonomic brain regions together control the cardiovascular system. Baroreflex sensitivity (BRS) decreases with age in adults. Age-related changes in brain regions for cardiovascular control in children are unknown. We studied age-related changes in BRS, cardiac autonomic tone, and gray matter volume (GMV) of brain regions associated with cardiovascular control.MethodsBeat-to-beat blood pressure and heart rate (HR) were recorded in 49 children (6-14 years old). Spontaneous BRS was calculated by the sequence method. Cardiac autonomic tone was measured by spectral analysis of HR variability. GMV was measured using voxel-based morphometryin 112 healthy children (5-18 years old).ResultsAge-related changes in BRS were significantly different in children <10 years and ≥10 years. Age-related changes in GMV in regions of interest (ROI) were also significantly different between children <10 and ≥10 years and between children <11 and ≥11 years. However, age-related changes in cardiac autonomic tone were progressive.ConclusionsSignificant changes in BRS trajectories between <10 and ≥10 years may be associated with similar age-related changes of GMV in brain ROI. This new knowledge will guide future studies examining whether childhood cardiovascular disruption manifests as deviated maturation trajectories of specific brain regions.

The Stability and Influence of Barriers to Medication Adherence on Seizure Outcomes and Adherence in Children With Epilepsy Over 2 Years.

Objective: To determine the stability and influence of adherence barriers on medication adherence and seizure control in pediatric epilepsy. Methods: Caregivers of 118 children aged 2-12 years old with epilepsy completed the Pediatric Epilepsy Medication Self-Management Questionnaire at nine time points over 2 years post diagnosis. Electronically monitored antiepileptic drug adherence and seizure outcome data were collected. Results: Hierarchical linear modeling results for overall barriers remained stable over 2 years. Specific item-level barriers were also generally stable over time, with the exception of running out of medication becoming more of a barrier over time. No specific barriers were related to seizure control; however, difficulties swallowing medication, forgetting, and medication refusal were related to electronically monitored adherence over time. Conclusions: Assessing for specific adherence barriers over time may lead to identification of interventions that result in improved adherence and care.
