RESUMO
BACKGROUND: Pediatric emergency departments (ED) are where many families receive post-concussion medical care and thus an important context for helping parents build skills to support their child after discharge. OBJECTIVE: Develop a strategy for increasing parent provision of emotional and instrumental support to their child after discharge and conduct a pilot test of this strategy's acceptability. METHODS: In a large pediatric ED in the United States, we partnered with parents (n = 15) and clinicians (n = 15) to understand needs and constraints related to discharge education and to operationalize a strategy to feasibly address these needs. This produced a brief daily text message intervention for parents for 10 days post-discharge. We used a sequential cohort design to assess the acceptability this intervention and its efficacy in changing parenting practices in the 2-weeks post-discharge (n = 98 parents). RESULTS: Parents who received the messaging intervention rated it as highly acceptable and had meaningfully higher scores for emotionally supportive communication with their child in the two weeks post-discharge than parents in the control condition (Cohen's d = 0.65, p = 0.021). CONCLUSIONS: This brief messaging intervention is a promising strategy for enhancing discharge education post-concussion that warrants further evaluation.

Fundamental to the quality of life is assisting patients in relieving pain including at the end of life. Compassionate, effective, evidence-based pain care for the dying improves the quality of life for patients and may reduce distress and complicated bereavement in the loved ones witnessing this death. However, efforts designed to mitigate the consequences of the opioid epidemic have seriously compromised pain care at the end of life. This has created an urgent need to focus on the barriers to relief, and solutions necessary to provide safe and effective pain and symptom management in this population. To that end, a committee of experts was convened by the American Society for Pain Management Nursing and the Hospice and Palliative Nursing Association. These experts reviewed the current literature, developed a draft position statement which underwent consecutive revisions. This statement was then endorsed by the respective organizations. Elucidation of barriers to effective pain control in advanced disease allows targeted interventions; including those related to clinical care, education, accessibility, and research. As nurses, we must continuously advocate for humane and dignified care, promoting ethical, effective pain and symptom management at the end of life for all.

Human norovirus (HuNoV) is an important cause of acute gastroenteritis and can be transmitted by water exposures, but its persistence in water is not well understood. Loss of HuNoV infectivity in surface water was compared with persistence of intact HuNoV capsids and genome segments. Surface water from a freshwater creek was filter-sterilized, inoculated with HuNoV (GII.4) purified from stool, and incubated at 15 or 20 °C. We measured HuNoV infectivity via the human intestinal enteroid system and HuNoV persistence via reverse transcription-quantitative polymerase chain reaction assays without (genome segment persistence) or with (intact viral capsid persistence) enzymatic pretreatment to digest naked RNA. For infectious HuNoV, results ranged from no significant decay to a decay rate constant ("k") of 2.2 day-1. In one creek water sample, genome damage was likely a dominant inactivation mechanism. In other samples from the same creek, loss of HuNoV infectivity could not be attributed to genome damage or capsid cleavage. The range in k and the difference in the inactivation mechanism observed in water from the same site could not be explained, but variable constituents in the environmental matrix could have contributed. Thus, a single k may be insufficient for modeling virus inactivation in surface waters.

OBJECTIVES: Determine whether Pre-Game Safety Huddles, a novel and low-resource approach to concussion education, increase the expected likelihood of concussion reporting for youth athletes. METHODS: A cluster-randomised trial compared Safety Huddles to usual care. Safety Huddles bring together athletes and coaches from both teams before the start of each game for coaches to briefly affirm the importance of speaking up if a concussion is suspected. Participants were athletes from 22 competitive community-based American football and girls and boys soccer teams (ages 9-14), and randomisation into intervention or control occurred at the level of the bracket (group of teams that compete against each other during the regular season). The primary outcome was expected likelihood of reporting concussion symptoms to the coach, measured via validated athlete survey at the beginning and end of the season. RESULTS: Of 343 eligible participants, 339 (99%) completed baseline surveys and 303 (88%) completed surveys at season end. The mean (SD) age was 11.4 (1.1) years, 26% were female soccer athletes, 27% were male soccer athletes and 47% were football athletes. In adjusted analyses accounting for baseline values and clustering by sport and team via random effects, expected likelihood of concussion reporting at the end of the season was significantly higher in the intervention group compared to controls (mean difference=0.49, 95% CI 0.11 to 0.88; Cohen's d=0.35). CONCLUSIONS AND RELEVANCE: Pre-Game Safety Huddles increased the expected likelihood of athletes reporting concussion symptoms. While further study is warranted, sport organisations should consider this approach a promising low-resource option for improving concussion safety in their setting. TRIAL REGISTRATION NUMBER: NCT04099329.

Concentrations of nucleic acids from a range of respiratory viruses in wastewater solids collected from wastewater treatment plants correlate to clinical data on disease occurrence in the community contributing to the wastewater. Viral nucleic acids enter wastewater from excretions deposited in toilets or drains. To relate measured concentrations in wastewater at a treatment plant to the number of community infections, viral nucleic-acid concentrations in human excretions are needed as inputs to a mass balance model. Here, we carried out a systematic review and meta-analysis to characterize the concentrations and presence of influenza A and B, respiratory syncytial virus, metapneumovirus, parainfluenza virus, rhinovirus, and seasonal coronaviruses in stool, urine, mucus, sputum, and saliva. We identified 220 data sets from 50 articles and reported viral concentrations and presence in these excretions. Data were unevenly distributed across virus type (with the most available for influenza) and excretion type (with the most available for respiratory excretions). Most articles only reported the presence or absence of the virus in a cross-sectional study design. There is a need for more concentration data, including longitudinal data, across all respiratory virus and excretion types. Such data would allow quantitatively linking virus wastewater concentrations to numbers of infected individuals.

OBJECTIVES: Previous research has shown racial, ethnic, and socioeconomic disparities in provider medical evaluations and reporting to child protective services (CPS) and law enforcement (LE) for cases of suspected child physical abuse. Our hospital standardized evaluation and reporting of high-risk bruising using a clinical pathway. We aimed to assess whether standardization impacted disparity. METHODS: We performed a retrospective observational study including children evaluated in the emergency department who had a social work consult for concern for child abuse or neglect between June 2012 and December 2019. From this group, we identified children with high-risk bruising. We compared outcomes (receipt of skeletal survey, CPS report, or LE report) before and after implementation of a standard bruising evaluation pathway to determine how the intervention changed practice among various racial, ethnic, and socioeconomic groups. RESULTS: During the study period, 2129 children presented to the ED and received a social work consult for child abuse or neglect. Of these, 333 had high-risk bruising. Children without private insurance had a higher risk of having a CPS (adjusted relative risk, 1.32; 95% confidence interval, 1.09-1.60) or LE (adjusted relative risk, 1.48; 95% confidence interval, 1.11-1.97) report prepathway, but not after pathway implementation. No significant associations were seen for race or ethnicity. CONCLUSIONS: A standardized clinical pathway for identification and evaluation of high-risk bruising may help to decrease socioeconomic disparities in reporting high-risk bruising. Larger studies are needed to fully evaluate disparities in assessment and reporting of child abuse.

Importance: An intervention model (the Parent-focused Redesign for Encounters, Newborns to Toddlers; the PARENT intervention) for well-child care that integrates a community health worker into preventive care services may enhance early childhood well-child care. Objective: To examine the effectiveness of the PARENT intervention vs usual care for parents with children younger than 2 years of age. Design, Setting, and Participants: A cluster randomized clinical trial was conducted between March 2019 and July 2022. Of the 1283 parents with a child younger than 2 years of age presenting for a well-child visit at 1 of the 10 clinic sites (2 federally qualified health centers in California and Washington) approached for trial participation, 937 were enrolled. Intervention: Five clinics implemented the PARENT intervention, which is a team-based approach to care that uses a community health worker in the role of a coach (ie, health educator) as part of the well-child care team to provide comprehensive preventive services, and 5 clinics provided usual care. Main Outcomes and Measures: There were 2 primary outcomes: score for parent-reported receipt of recommended anticipatory guidance during well-child visits (score range, 0-100) and emergency department (ED) use (proportion with ≥2 ED visits). The secondary outcomes included psychosocial screening, developmental screening, health care use, and parent-reported experiences of care. Results: Of the 937 parents who were enrolled, 914 remained eligible to participate (n = 438 in the intervention group and n = 476 in the usual care group; 95% were mothers, 73% reported Latino ethnicity, and 63% reported an annual income <$30â¯000). The majority (855/914; 94%) of the children (mean age, 4.4 months at parental enrollment) were insured by Medicaid. Of the 914 parents who remained eligible and enrolled, 785 (86%) completed the 12-month follow-up interview. Parents of children treated at the intervention clinics (n = 375) reported receiving more anticipatory guidance than the parents of children treated at the usual care clinics (n = 407) (mean score, 73.9 [SD, 23.4] vs 63.3 [SD, 27.8], respectively; adjusted absolute difference, 11.01 [95% CI, 6.44 to 15.59]). There was no difference in ED use (proportion with ≥2 ED visits) between the intervention group (n = 376) and the usual care group (n = 407) (37.2% vs 36.1%, respectively; adjusted absolute difference, 1.2% [95% CI, -5.5% to 8.0%]). The effects of the intervention on the secondary outcomes included a higher amount of psychosocial assessments performed, a greater number of parents who had developmental or behavioral concerns elicited and addressed, increased attendance at well-child visits, and greater parental experiences with the care received (helpfulness of care). Conclusions and Relevance: The intervention resulted in improvements in the receipt of preventive care services vs usual care for children insured by Medicaid by incorporating community health workers in a team-based approach to early childhood well-child care.

Aerosol transport of enteric microbiota including fecal pathogens and antimicrobial resistance genes (ARGs) has been documented in a range of settings but remains poorly understood outside indoor environments. We conducted a systematic review of the peer-reviewed literature to summarize evidence on specific enteric microbiota including enteric pathogens and ARGs that have been measured in aerosol samples in urban settings where the risks of outdoor exposure and antibiotic resistance (AR) spread may be highest. Following PRISMA guidelines, we conducted a key word search for articles published within the years 1990-2020 using relevant data sources. Two authors independently conducted the keyword searches of databases and conducted primary and secondary screenings before merging results. To be included, studies contained extractable data on enteric microbes and AR in outdoor aerosols regardless of source confirmation and reported on qualitative, quantitative, or viability data on enteric microbes or AR. Qualitative analyses and metric summaries revealed that enteric microbes and AR have been consistently reported in outdoor aerosols, generally via relative abundance measures, though gaps remain preventing full understanding of the role of the aeromicrobiological pathway in the fate and transport of enteric associated outdoor aerosols. We identified remaining gaps in the evidence base including a need for broad characterization of enteric pathogens in bioaerosols beyond bacterial genera, a need for greater sampling in locations of high enteric disease risk, and a need for quantitative estimation of microbial and nucleic acid densities that may be applied to fate and transport models and in quantitative microbial risk assessment.

Urban sanitation infrastructure is inadequate in many low-income countries, leading to the presence of highly concentrated, uncontained fecal waste streams in densely populated areas. Combined with mechanisms of aerosolization, airborne transport of enteric microbes and their genetic material is possible in such settings but remains poorly characterized. We detected and quantified enteric pathogen-associated gene targets in aerosol samples near open wastewater canals (OWCs) or impacted (receiving sewage or wastewater) surface waters and control sites in La Paz, Bolivia; Kanpur, India; and Atlanta, USA, via multiplex reverse-transcription qPCR (37 targets) and ddPCR (13 targets). We detected a wide range of enteric targets, some not previously reported in extramural urban aerosols, with more frequent detections of all enteric targets at higher densities in La Paz and Kanpur near OWCs. We report density estimates ranging up to 4.7 × 102 gc per mair3 across all targets including heat-stable enterotoxigenic Escherichia coli, Campylobacter jejuni, enteroinvasive E. coli/Shigella spp., Salmonella spp., norovirus, and Cryptosporidium spp. Estimated 25, 76, and 0% of samples containing positive pathogen detects were accompanied by culturable E. coli in La Paz, Kanpur, and Atlanta, respectively, suggesting potential for viability of enteric microbes at the point of sampling. Airborne transmission of enteric pathogens merits further investigation in cities with poor sanitation.

PURPOSE: Foster youth have high rates of unintended teen pregnancies and other negative sexual health outcomes. Foster and kinship caregivers (FKC) are an untapped resource to reduce risks. We conducted a two-phase pilot study to evaluate feasibility, acceptability and assess preliminary efficacy of a training designed to improve caregiver communication, monitoring and conflict behaviors and improve sexual health outcomes for youth in foster care. Our study included a Randomized Controlled Trial (RCT) component. METHOD: Phase 1: We recruited 49 FKC and assessed feasibility quantitatively, and acceptability both qualitatively and quantitatively of our intervention (Heart to Heart). Phase 2: We conducted an RCT with 71 participants and evaluated caregiver communication, monitoring, and conflict behaviors as well as the psychological determinants thereof in intervention and control groups at 1, 3, and 6 months. RESULTS: Phase 1: Facilitators delivered all intervention content; >90% participants received the entire training. The intervention was highly acceptable (mean score 4.9/5 on two questions). Phase 2: 71 participants were eligible and completed baseline (68 completed at least one follow up survey). We found significant improvements in the intervention group in knowledge, communication expectations, and caregiver-youth conflict behaviors in one or more waves; the control group demonstrated no significant improvements. When groups were compared, we found significant differences in knowledge, communication frequency, and conflict behaviors at 6 months. CONCLUSIONS: Heart to Heart is feasible, acceptable, and preliminary outcomes data is promising. More research is needed to better establish evidence of efficacy for long-term behavior change in caregivers and youth. CLINICALTRIALSGOV IDENTIFER: NCT03331016.
RESUMO
BACKGROUND: Accurately measuring parents' attitudes and beliefs regarding limiting their children's TV viewing is important to inform the design and evaluation of effective interventions. This manuscript assesses the internal consistency reliability, test-retest reliability, convergent validity, and construct validity of the Model of Goal Directed Behavior (MGDB) scales among parents of Latino preschoolers to characterize Latino parents' attitudes and beliefs toward limiting their preschoolers' TV viewing. METHOD: Participants included parents of Latino preschoolers in the United States, 3-5 years old (n = 186). Parents completed a socio-demographic survey and the 105-item MGDB questionnaire (Attitudes, Perceived Positive/Negative Behavioral Control, Subjective Norms, Positive and Negative Anticipated Emotions, Habits, Self-Efficacy, Desires, and Intentions surrounding their child's TV viewing) which was used to measure internal consistency reliability and construct validity. A subsample of participants completed the questionnaire twice to measure test-retest reliability. Further, parents completed a 7-day TV viewing diary for their preschooler, and a TV parenting practices questionnaire as measures of convergent validity. RESULTS: Internal consistency reliability was generally acceptable for the MGDB scales (Cronbach's alphas> 0.7), except for the Desires scale, which was revealed to have two factors and the Attitudes and Perceived Behavioral Control scales. Test-retest reliability over 2 months had negligible to moderate correlations (r's = 0.28 to 0.61). Two structural equation models were conducted. One yielded acceptable model fit (x2 (97) = 113.65, p = .119) and the other had questionable model fit (x2 (97) = 125.39; p = .028). Testing convergent validity, only two MGDB scales (Habits and Self-Efficacy) were positively correlated with the TV parenting practices questionnaire (r's = 0.33 to 0.51), and none were meaningfully correlated with preschoolers' mean daily TV viewing. CONCLUSIONS: Initial reliability and validity for some of the MGDB scales appear acceptable among parents of Latino preschoolers. Refinement of the instrument and testing among larger samples is necessary to fully evaluate psychometric properties. This instrument may be useful for characterizing Latino parents' attitudes and beliefs toward limiting their preschoolers' TV viewing and informing future TV reduction interventions.

OBJECTIVE: To collect prospective data on concussion incidence, risk factors, duration of symptoms, and return to school and sport in 5- to 14-year-old American football participants. STUDY DESIGN: We conducted a prospective cohort study over 2 years collecting data during two 10-week fall seasons. Youth with concussion were followed to determine time to return to school, sport, and baseline level of symptoms. Logistic regression was used to estimate the risk of sustaining a concussion associated with baseline demographic factors. Time to return to school, sport, and baseline symptoms were analyzed using Kaplan-Meier survival curves. RESULTS: Of 863 youth followed (996 player-seasons), 51 sustained a football-related concussion, for an athlete-level incidence of 5.1% per season. Youth with history of concussion had a 2-fold increased risk for sustaining an incident concussion (OR, 2.2; 95% CI, 1.1-4.8). Youth with depression had a 5-fold increased risk of concussion (OR, 5.6; 95% CI, 1.7-18.8). After a concussion, 50% of athletes returned to school by 3 days, 50% returned to sport by 13 days, and 50% returned to a baseline level of symptoms by 3 weeks. CONCLUSIONS: Concussion rates in this study were slightly higher than previously reported, with 5 of every 100 youth sustaining a football-related concussion each season. One-half of youth were still symptomatic 3 weeks after injury. Further research is needed to address the risk of concussion in youth football.

OBJECTIVE: To examine variation in head impact exposure (HIE) by age and sex in youth soccer. DESIGN: Prospective cohort study. SETTING AND PARTICIPANTS: Youth soccer athletes (11-14 years old) in local clubs. EXPOSURES: Age and sex. OUTCOME MEASURES: Head impact exposure measured using adhesive-mounted accelerometers during 1 month of soccer. RESULTS: Forty-six youth athletes (54% female) participated. No athlete reported a concussion during the study. More males than females had at least 1 head impact ≥15 g (P = 0.02). Of those who sustained a head impact above the 15-g threshold (57%), females sustained HIE of greater magnitude than males (median 47.4 g vs 33.3 g, P = 0.04). Eighty-five percent of athletes on U14 teams had at least 1 head impact ≥15 g compared with 15% of athletes on U12 teams (P < 0.001). Poisson regression stratified by sex and controlling for team-suggested age effects were significant only for females (P = 0.02). There was significant variation in HIE by team. There were no decrements in concussion symptoms, health-related quality of life, or neuropsychological testing after 1 month of soccer play. CONCLUSIONS: There is significant variation in HIE in youth soccer, which seems to be influenced by age and sex. Further studies are needed to better understand potential significance for injury prevention.

PURPOSE: Exposure to asbestos is thought to cause the large majority of pleural mesotheliomas in the USA. It is unknown whether asbestos exposure plays a role in the etiology of rarer forms of mesothelioma, e.g., those located in the pericardium or in the tunica vaginalis of the testis. In order to address this question, we sought to determine whether geographic patterns of incidence of these mesotheliomas have paralleled those of pleural mesotheliomas. METHODS: We used age-adjusted incidence data from the nine populations served by the National Cancer Institute's Surveillance, Epidemiology, and End Results program during 1973-2011. Among men ages ≥50 years, we compared the incidence of pericardial and paratesticular mesotheliomas, respectively, with the incidence of pleural mesothelioma across the nine populations. RESULTS: The rate of pleural mesothelioma was approximately twice as high in the San Francisco-Oakland (SFO) and Seattle-Puget Sound (SPS) areas compared to the other regions. In contrast, rates of paratesticular and pericardial mesotheliomas were not elevated in SFO (n = 3 paratesticular, 1 pericardial) or SPS (n = 4 paratesticular, 1 pericardial) relative to other regions. CONCLUSIONS: The results of this ecologic study do not support a role for asbestos exposure in the etiologies of either pericardial or paratesticular mesotheliomas; however, this study was limited by small numbers and was unable to directly ascertain asbestos exposure.

PURPOSE: Studies have suggested that a history of migraines may be associated with a lower risk of some types of breast cancer, though biological mechanisms are unclear. Identifying specific characteristics of migraines which are most strongly associated with breast cancer risk could improve our understanding of this relationship. METHODS: We ascertained specific characteristics of women's migraine histories (severity, timing features, and presence of migraine aura). We used polytomous logistic regression to estimate the risk of ER+ ductal, ER- ductal, ER+ lobular, and ER+ ductal-lobular breast cancer associated with self-reported characteristics of migraine history. A total of 715 breast cancer cases (276 ER+ ductal, 46 ER- ductal, 191 ER+ lobular, and 202 ER+ ductal-lobular) and 376 controls ages 55-74 years were included in this population-based case-control study. RESULTS: Compared to women without a migraine history, women with a >30-year history of migraines had a 60 % (95 % CI 0.2-0.6) lower risk of ER+ ductal breast cancer; those who had their first migraine before age 20 had 50 % lower risks of ER+ ductal and ER+ lobular breast cancer (both 95 % CIs 0.3-0.9), and women who experienced migraine with aura had 30 % (95 % CI 0.5-0.98) and 40 % (95 % CI 0.4-0.9) lower risks of ER+ ductal and ER+ lobular breast cancer, respectively. CONCLUSION: The lower risk of ER+ breast cancer associated with migraine appears to be limited to those women with early onset or long duration of migraine history, or those who experienced migraine with aura. This expands our understanding of the relationship between migraine and breast cancer and provides additional insight into potential underlying biological mechanisms.

Modeling the fate and transport of viruses and their genetic material in surface water is necessary to assess risks associated with contaminated surface waters and to inform environmental surveillance efforts. Temperature has been identified as a key variable affecting virus persistence in surface waters, but the effects of the presence of biological and inert particles and of their interaction with temperature have not been well characterized. We assessed these effects on the persistence of human norovirus (HuNoV) genotype II.4 purified from stool and MS2 in surface water. Raw or filter-sterilized creek water microcosms were inoculated and incubated in the dark at 10 °C, 15 °C, and 20 °C. HuNoV (i.e., genome segments and intact capsids) and MS2 (i.e., infectious MS2, genome segments, and intact capsids) concentrations were followed over 36 days. The range in positive, significant first-order decay rate constants for HuNoV in this study was 0.14 to 0.69 day-1 compared with 0.026 to 0.71 day-1 for that of MS2. Decay rate constants for HuNoV genome segments and infectious MS2 were largest in creek water that included biological and inert particles and incubated at higher temperatures. In addition, for HuNoV and MS2 incubated in raw or filter-sterilized creek water at 15 °C, capsid damage was not identified as a dominant inactivation mechanism. Environmental processes and events that affect surface water biological and inert particles, temperature, or both could lead to variable virus decay rate constants. Incorporating the effects of particles, temperature, and their interaction could enhance models of virus fate and transport in surface water.

Pediatric MASLD (previously referred to as NAFLD) incidence has continued to rise along with the obesity pandemic. Pediatric MASLD increases the risk of liver fibrosis and cirrhosis in adulthood. Early detection and intervention can prevent and reduce complications. Liver biopsy remains the gold standard for diagnosis, although imaging modalities are increasingly being used. We performed a retrospective study of 202 children seen in a pediatric gastroenterology clinic with a complaint of abdominal pain, elevated liver enzymes or MASLD, or a combination of the three to evaluate screening methods for MASLD. A total of 134 of the 202 patients included in the study underwent laboratory testing and abdominal ultrasound. Ultrasound images were reviewed with attention to liver size and echotexture by a fellowship-trained pediatric radiologist for liver size and echotexture. Overall, 76.2% of the initial radiology reports correctly identified hepatomegaly based on age and 75.4% of the initial radiology reports correctly described hepatic echogenicity that was consistent with increased hepatic fat deposition. Use of screening ultrasound in concert with other clinical evaluations can be helpful to identify children at risk of MASLD. Utilizing ranges for liver span according to age can help to diagnose hepatomegaly, and understanding how to identify hepatic echogenicity is important for identifying possible hepatic steatosis.
RESUMO
Valley Fever is a respiratory disease caused by inhalation of arthroconidia, a type of spore produced by fungi within the genus Coccidioides spp. which are found in dry, hot ecosystems of the Western Hemisphere. A quantitative microbial risk assessment (QMRA) for the disease has not yet been performed due to a lack of dose-response models and a scarcity of quantitative occurrence data from environmental samples. A literature review was performed to gather data on experimental animal dosing studies, environmental occurrence, human disease outbreaks, and meteorological associations. As a result, a risk framework is presented with information for parameterizing QMRA models for Coccidioides spp., with eight new dose-response models proposed. A probabilistic QMRA was conducted for a Southwestern US agricultural case study, evaluating eight scenarios related to farming occupational exposures. Median daily workday risks for developing severe Valley Fever ranged from 2.53 × 10-7 (planting by hand while wearing an N95 facemask) to 1.33 × 10-3 (machine harvesting while not wearing a facemask). The literature review and QMRA synthesis confirmed that exposure to aerosolized arthroconidia has the potential to result in high attack rates but highlighted that the mechanistic relationships between environmental conditions and disease remain poorly understood. Recommendations for Valley Fever risk assessment research needs in order to reduce disease risks are discussed, including interventions for farmers.

PURPOSE: Foster youth are at increased risk for negative sexual health outcomes and rarely receive the information or social/familial support needed to reduce risks. Foster and kinship caregivers report lacking the information and skills needed to effectively talk to youth in their care about sexual health. In a sample of caregivers from 2 large urban jurisdictions, our goals were to: 1) describe caregiver sexual health variables including communication and monitoring characteristics; and 2) assess associations between self-reported emotion regulation and caregiver-youth conflict and these variables. METHODS: We administered surveys to foster and kinship caregivers in New York, New York and Los Angeles, California. Surveys assessed caregiver emotion regulation, caregiver-youth conflict, sexual/reproductive health knowledge, communication expectations and behaviors, and caregiver monitoring/youth disclosure. We generated descriptive statistics for all variables (aim 1) then performed multivariate regression analyses for aim 2. RESULTS: Our sample included 127 foster and kinship caregivers who were primarily female (92%) and African American (55%). Most reported having >4 years of caregiving experience with foster youth (66%). On average, caregivers answered sexual health knowledge questions correctly 68% of the time. Caregiver-youth conflict was the only variable significantly associated with assessed sexual health variables; it was inversely associated with percent correct on the knowledge scale, outcomes expectations, number of topics discussed, and monitoring/disclosure. CONCLUSION: Our study suggests that caregiver-youth conflict behaviors are related to sexual health knowledge, communication, and monitoring variables. Further prospective and longitudinal investigation is warranted to better characterize the complex relationship between these variables.

Abstract Assessing parent readiness to support their child's post-concussion management requires valid and reliable measures. Therefore, the objective of this study was to develop and conduct preliminary tests of reliability and validity of survey measures of parent concussion management knowledge and self-efficacy. Additionally, we tested the hypothesis that among parents of youth who had sustained a concussion, higher scores on measures of knowledge and self-efficacy would predict greater likelihood of engaging in recommended concussion management behaviors during their child's recovery. Measure development occurred with reference to parenting behaviors included in the Center for Disease Control and Prevention's Pediatric Mild Traumatic Brain Injury (mTBI) Management Guidelines. A multi-stage mixed- methods approach was employed, including expert review, cognitive interviews with parents, quantitative item reduction, and tests of reliability and validity. All participants were English-speaking parents of school-aged children in the United States. A stepwise measure development process was followed, with different participant groups across steps (including opt-in web-based survey panels and in-person recruitment from the population of parents of pediatric patients seen in a large pediatric emergency department). In total, 774 parents participated in study activities. The final knowledge index had 10 items, and the final self-efficacy scale had 13 items across four subscales (emotional support, rehabilitation support, monitoring, and external engagement). Internal consistency reliability was 0.63 for the knowledge index and 0.79-0.91 for self-efficacy sub-scales, and validation tests were in the hypothesized directions. In a test of predictive validity, we observed that among parents of youth patients with recent concussion, higher self-efficacy scores at the time of discharge from the pediatric emergency department were positively correlated (r = 0.12) with greater likelihood of engaging in recommended support behaviors at 2-week follow-up. There was no association between concussion management knowledge at discharge and parenting behaviors at follow-up. Parents have the potential to play an important role in concussion management. The measures of knowledge and self-efficacy developed in this study can help identify parent needs and evaluate interventions aiming to support parenting post-concussion.
