Reporting and Description of Research Methodology in Studies Estimating Effects of Firearm Policies.

BACKGROUND: Evidence about which firearm policies work, to what extent, and for whom is hotly debated, perhaps partly because variation in research methodology has produced mixed and inconclusive effect estimates. We conducted a scoping review of firearm policy research in the health sciences in the United States, focusing on methodological considerations for causal inference. METHODS: We identified original, empirical articles indexed in PubMed from 1/1/2000-9/1/2021 that examined any of 18 pre-specified firearm policies. We extracted key study components, including policy type(s) examined, policy operationalization, outcomes, study setting and population, study approach and design, causal language, and whether and how authors acknowledged potential sources of bias. RESULTS: We screened 7733 articles and included 124. A plurality of studies used a legislative score as their primary exposure (n=39; 32%) and did not examine change in policies over time (n=47; 38%). Most examined firearm homicide (n=51; 41%) or firearm suicide (n=40; 32%) as outcomes. One-third adjusted for other firearm policies (n=41; 33%). Three studies (2%) explicitly mentioned that their goal was to estimate causal effects, but over half used language implying causality (n=72; 58%). Most acknowledged causal identification assumptions of temporality (n=91; 73%) and exchangeability (n=111; 90%); other assumptions were less often acknowledged. One-third of studies included bias analyses (n=42; 34%). CONCLUSIONS: We identified a range of methodologic approaches in firearm policy research in the health sciences. Acknowledging limitations of data availability and quality, we identify opportunities to improve causal inferences about and reporting on the effects of firearm policies on population health.

Development of the Preschool Life Impact Burn Recovery Evaluation (PS-LIBRE1-5) Profile.

Physical, social, and psychological outcomes have been identified as relevant to the rehabilitation process of children with burn injuries. Existing legacy measures are limited in item content and only cover a few constructs. Condition-specific outcomes are highly relevant to gauge early growth and development. Computerized adaptive tests (CATs) leveraging advanced psychometric technologies minimize respondent burden. This project developed PS-LIBRE1-5 Profile CAT (Preschool Life Impact Burn Recovery Evaluation) to measure relevant postburn outcomes in children aged one to five. Responses to the field-tested PS-LIBRE1-5 Profile (188 items) were measured on a scale of frequency or ability. Scores were coded from 0 to 4 where higher scores reflected better functioning. Factor analysis identified the items retained in the final item bank of each scale. CAT simulations were conducted to estimate the mean score of each scale. The simulated CAT score and full item bank scores were compared based upon the score range, ceiling and floor effects, and marginal reliabilities. The child mean age was 3.0 ± 1.5 years (n = 500). Average burn size and time since burn injury were 4.2% TBSA and 1.1 years, respectively. Psychometric analysis resulted in eight scales: Physical, Communication and Language, Emotional Wellbeing, Mood, Anxiety, Peer Acceptance, Play, and Peer Relations. Ceiling effects were acceptable at <13% for all scales. Marginal reliabilities of the CATs were credible. The PS-LIBRE1-5 Profile CAT contains 111 items, and is a comprehensive measure that captures physical, communication and language, psychological, and social functioning of preschool burn survivors.

Systematic review of global hepatitis E outbreaks to inform response and coordination initiatives.

INTRODUCTION: Hepatitis E virus (HEV) is the most common cause of acute hepatitis. While symptoms are generally mild and resolve within weeks, some populations (e.g., pregnant women, immunocompromised adults) are at high-risk of severe HEV-related morbidity and mortality. There has not been a recent comprehensive review of contemporary HEV outbreaks, which limits the validity of current disease burden estimates. Therefore, we aimed to characterize global HEV outbreaks and describe data gaps to inform HEV outbreak prevention and response initiatives. METHODS: We performed a systematic review of peer-reviewed (PubMed, Embase) and gray literature (ProMED) to identify reports of outbreaks published between 2011 and 2022. We included (1) reports with ≥ 5 cases of HEV, and/or (2) reports with 1.5 times the baseline incidence of HEV in a specific population, and (3) all reports with suspected (e.g., clinical case definition) or confirmed (e.g., ELISA or PCR test) cases if they met criterium 1 and/or 2. We describe key outbreak epidemiological, prevention and response characteristics and major data gaps. RESULTS: We identified 907 records from PubMed, 468 from Embase, and 247 from ProMED. We screened 1,362 potentially relevant records after deduplication. Seventy-one reports were synthesized, representing 44 HEV outbreaks in 19 countries. The populations at risk, case fatalities, and outbreak durations were not reported in 66% of outbreak reports. No reports described using HEV vaccines. Reported intervention efforts included improving sanitation and hygiene, contact tracing/case surveillance, chlorinating boreholes, and advising residents to boil water. Commonly missing data elements included specific case definitions used, testing strategy and methods, seroprevalence, impacts of interventions, and outbreak response costs. Approximately 20% of HEV outbreaks we found were not published in the peer-reviewed literature. CONCLUSION: HEV represents a significant public health problem. Unfortunately, extensive data shortages and a lack of standardized reporting make it difficult to estimate the HEV disease burden accurately and to implement effective prevention and response activities. Our study has identified major gaps to guide future studies and outbreak reporting systems. Our results support the development of standardized reporting procedures/platforms for HEV outbreaks to ensure accurate and timely data distribution, including active and passive coordinated surveillance systems, particularly among high-risk populations.

"We Should Be Taught Self-Respect, Self-Confidence and Self-Love": Youth Perspectives of Adult Influences on Their Sexuality and Relationships Among South African Adolescents Living With HIV.

Introduction: Of the 1.75 million adolescents aged 10-19 years living with HIV globally, 84% reside in sub-Saharan Africa. This problem is most acute in South Africa, where there are 720,000 adolescents living with HIV (ALHIV). ALHIV navigate the same challenges as other adolescents-such as puberty and first relationships-as well as challenges specific to their HIV-status-including stigma, disclosure, and concerns about HIV transmission. This dual burden calls for tailored sexual and reproductive health (SRH) programs. Here, we qualitatively explore the reflections of South African ALHIV on SRH education, communication, and discussion provided by adults in schools, clinics, and the home related to their unique SRH needs. Methods: This paper reports on qualitative data from a mixed-methods study to inform interventions that meet the SRH needs of ALHIV. In-depth interviews (N = 20) were conducted with ALHIV recruited from two clinics in Cape Town, South Africa. Nine males and 11 females aged 16-19 participated in semi-structured in-depth interviews to discuss their sexual health as ALHIV. The interview guide explored 1) perceived SRH needs; 2) healthy living with HIV; 3) future goals; 4) intimate relationships; 5) psychosocial challenges; and 6) preferred interventions. Data were thematically applied to an iteratively-developed codebook and analyzed by the cross-cultural research team using NVivo 12. Results: These qualitative data reveal the pressing needs among ALHIV for open communication and accurate information about sexuality and HIV, given the risk to themselves and their partners as they enter intimate relationships. Three themes emerged from the data: 1) Intergenerational pressures coming from caregivers, clinicians, and teachers often stigmatize the sexual heath behaviors of ALHIV; 2) When present, open intergenerational communication can provide ALHIV with crucial information, resources, and social support that supports healthy decisions, and 3) ALHIV offer specific ideas about how adults can support their decision-making in the transition to adulthood. Conclusions: Findings highlight adolescents' recommendations for programs involving open communication, stigma-reduction around sexuality, and support from both peer and adult mentors. This study lays the foundation for strategies to improve intergenerational communication about sexual health to promote positive approaches to sexuality for ALHIV.

Challenges of devising a milk recipe in a hand-reared hippopotamus (Hippopotamus amphibius).

In January 2017, a Nile hippopotamus (Hippopotamus amphibious) was born approximately six weeks premature at the Cincinnati Zoo & Botanical Garden. Due to the calf's weakened condition and lack of interest from the dam, management at the zoo made the decision to hand-rear the calf. Limited published information was available on hand-rearing this species of hippopotamus (hippo). To devise a nutritionally appropriate recipe, milk samples were acquired from the dam on Days 1, 3, 8, and 9 postpartum, and assayed for sugar, protein, fat, mineral, and water content using standard methods validated for multiple species of mammals at the Smithsonian National Zoo's Nutrition Science Laboratory. The sugar content stayed relatively constant (mean = 4.5%; range: 4.3%-4.7%). The fat consistently increased from 0.48% to 4.24% (mean = 2%). Excluding Day 9, the protein content gradually decreased from 9.56% to 6.39% (mean = 8%). The dry matter (DM) ranged from 14.38% to 16.72% (i.e., water content of 85.62%-83.28%), with the sum of the solids (sugar, protein, fat, and ash) averaging 98.5% of measured DM. Fat content was lower than expected but within the range of other artiodactyls. Between Days 1 and 8, the trend of decreasing protein and increasing fat was consistent with a change from colostrum to mature milk. The sharp increase in fat and protein with a decrease in sugar on Day 9 may indicate the beginning of the involution of the mammary gland due to lack of nursing stimulus. Utilizing this information, the Cincinnati Zoo was able to formulate a successful milk replacement recipe that allowed the calf to be raised through weaning to maturity.

The Impact of Burn Size on Community Participation: A Life Impact Burn Recovery Evaluation (LIBRE) Study.

OBJECTIVE: To assess the association of burn size and community participation as measured by the LIBRE Profile. SUMMARY OF BACKGROUND DATA: Burn size is an established clinical predictor of survival after burn injury. It is often a factor in guiding decisions surrounding early medical interventions; however, literature is inconclusive on its relationship to quality of life outcomes. METHODS: This is a secondary data analysis of a cross-sectional survey of adult burn survivors. Self-reported data were collected between October 2014 and December 2015 from 601 burn survivors aged ≥18 years with ≥5% total body surface area (TBSA) or burns to critical areas. Sociodemographic characteristics were compared between participants with small burns (≤40% TBSA burned) and large burns (>40% TBSA burned). Ordinary least squares regression models examined associations between burn size and LIBRE Profile scale scores with adjustments for sex, current work status, burns to critical areas, and time since burn injury. RESULTS: The analytic sample comprised 562 participants with data available for burn size. 42% of respondents had large burns (>40% TBSA burned) and 58% reported smaller burns (TBSA ≤40%). In adjusted regression models, patients with large burns tended to score lower on the Social Activities and Work & Employment scales ( P < 0.05) and higher on the Family & Friends scale ( P < 0.05). Participants with burns >40% TBSA scored lower for several individual items in the Social Activities scale and one item in the Work & Employment scale ( P < 0.05). CONCLUSIONS: Increasing burn size was found to be negatively associated with selected items of Work & Employment and Social Activities, but positively associated with aspects of Family & Friend Relationships. Future longitudinal studies are necessary to assess and understand the long-term social impact of burn injuries on adult populations.

Item Pool Development for the School-Aged Life Impact Burn Recovery Evaluation Profile Computerized Adaptive Test: An Observer-Reported Outcome Assessment Measuring the Impact of Burn Injuries in School-Aged Children.

The transition from early childhood to teen years (5-12) is a critical time of development, which can be made particularly challenging by a burn injury. Assessing postburn recovery during these years is important for improving pediatric survivors' development and health outcomes. Few validated burn-specific measures exist for this age group. The purpose of this study was to generate item pools that will be used to create a future computerized adaptive test (CAT) assessing postburn recovery in school-aged children. Item pool development was guided by the previously developed School-Aged Life Impact Burn Recovery Evaluation (SA-LIBRE5-12) conceptual framework. The item pool development process involved a systematic literature review, extraction of candidate items from existing legacy measures, iterative item review during expert consensus meetings, and parent cognitive interviews. The iterative item review with experts consisted of six rounds. A total of 10 parent cognitive interviews were conducted. The three broad themes of concern were items that needed 1) clarification, needed context, or were vague, 2) age dependence and relevance, and 3) word choice. The cognitive interviews indicated that survey instructions, recall period, item stem, and response choices were interpretable by respondents. Final item pool based on parental feedback consists of 57, 81, and 60 items in physical, psychological, and family and social functioning, respectively. Developed item pools (n = 198) in three domains are consistent with the existing conceptual framework. The next step involves field testing the item pool and calibration using item response theory to develop and validate the SA-LIBRE5-12 CAT Profile.

Physical, Psychological, and Social Outcomes in Pediatric Burn Survivors Ages 5 to 18 Years: A Systematic Review.

Acute pediatric burn injuries often result in chronic sequelae that affect physical, psychological, and social outcomes. To date, no review has comprehensively reported on the impact of burn injuries across all three domains in school-aged children. The aim of this systematic review was to identify published literature that focuses on the impact of burn injuries on physical, psychological, or social functioning, and report upon the nature of study characteristics and their outcomes. We included literature published after 1980, focusing on burn outcomes in children aged 5 to 18 years. Each eligible study was systematically reviewed and primary outcomes were classified into outcome domains based on existing frameworks. Fifty-eight studies met inclusion criteria, and reported on physical (n = 24), psychological (n = 47), and social (n = 29) domains. The majority of the studies had sample sizes of <100 participants, burn size of <40%, and findings reported by parents and/or burn survivors. Only eight of 107 different measures were used in three or more studies. Parents and burn survivors generally reported better physical and social outcomes and worse psychological functioning compared to non-burn populations. Physical disabilities were associated with psychological and social functioning in several studies. Follow-up data reported improvements across domains. This review demonstrates the importance of physical, psychological, and social status as long-term outcomes in burn survivors. Mixed findings across three outcome domains warrant long-term research. Findings of this review will guide the foundation of comprehensive burn and age-specific instruments to assess burn recovery.

Development of the School-Aged Life Impact Burn Recovery Evaluation (SA-LIBRE5-12) Profile: A Conceptual Framework.

Pediatric burn injuries can alter the trajectory of the survivor's entire life. Patient-centered outcome measures are helpful to assess unique physical and psychosocial needs and long-term recovery. This study aimed to develop a conceptual framework to measure pediatric burn outcomes in survivors aged 5 to 12 years as a part of the School-Aged Life Impact Burn Recovery Evaluation Computer Adaptive Test (SA-LIBRE5-12 CAT) development. This study conducted a systematic literature review guided by the WHO International Classification of Functioning-Child and Youth and domains in the American Burn Association/Shriners Hospitals for Children Burn Outcomes Questionnaire5-18. Interviews with eight parents and seven clinicians were conducted to identify important domains in child recovery. One clinician focus group with four clinicians was completed to identify gaps in the preliminary framework, and semiweekly expert consensus meetings were conducted with three experts to solidify the framework. Qualitative data were analyzed by grounded theory methodology. Three major thematic outcome domains emerged: 1) Physical Functioning: fine motor and upper extremity, gross motor and lower extremity, pain, skin symptoms, sleep and fatigue, and physical resilience; 2) Psychological Functioning: cognitive, behavioral, emotional, resilience, and body image; and 3) Family and Social Functioning: family relationships, and parental satisfaction, school, peer relations, and community participation. The framework will be used to develop item banks for a CAT-based assessment of school-aged children's health and developmental outcomes, which will be designed for clinical and research use to optimize interventions, personalize care, and improve long-term health outcomes for burned children.

"Those People Motivate and Inspire Me to Take My Treatment." Peer Support for Adolescents Living With HIV in Cape Town, South Africa.

Adherence to antiretroviral therapy (ART) and psychosocial support to manage stigma and disclosure is essential for adolescents living with HIV (ALHIV). Peer support groups can help ALHIV and their families live successfully with HIV. This qualitative study aimed to examine adolescent and caregiver perspectives on peer support groups. Three themes emerged: (1) peer support encouraged adherence to ART, (2) serostatus disclosure outside the family was perceived as difficult, and (3) the peer support group fostered fundamental and meaningful peer relationships for ALHIV. Caregivers felt peer support groups increased self-acceptance and adherence for ALHIV across 3 domains: (1) as motivation for families and adolescents, (2) to increase adolescent independence and maturity, and (3) to help adolescents accept their HIV status and live successfully with HIV. These data highlight the importance of psychosocial support groups for ALHIV and caregivers, illustrating the benefits of a safe space with trusted relationships and open communication.

Agreement between proxy- and self-report scores on PROMIS health-related quality of life domains in pediatric burn survivors: a National Institute on Disability, Independent Living, and Rehabilitation Research Burn Model System Study.

PURPOSE: To examine agreement between pediatric burn survivor self- and caregiver proxy-report on multiple PROMIS domains and examine factors associated with differences between self- and proxy-reports. METHODS: Children 8-17 years of age and their caregivers completed PROMIS measures (physical function, depression, peer relationships, pain interference, and anger) between 6 months and 15 years after injury. Self- and proxy-report scores were compared using Wilcoxon sign rank test, Cohen's effect size, and intraclass correlation coefficients (ICC) and by agreement across severity of symptoms based on recommended cutoffs. Ordinary least squares regression analyses examined child- (self-report score, age, gender, and ethnicity) and proxy-related (relationship to child) factors associated with score differences. RESULTS: Two hundred and seventy four child-caregiver pairs completed the PROMIS measures. Mean child age was 13.0 (SD:3) years. Caregivers reported significantly worse scores than the child on physical function, pain, and anger (all p ≤ 0.01). The effect sizes were small across all domains except physical function. Similarly, ICCs were all of moderate agreement. The percentage of dyads in agreement by severity groups was high with only 5%-9% of pairs discordant. Only higher self-report score was associated (all p < 0.05) with greater differences across all domains in regression analyses. CONCLUSIONS: This study supports the use of pediatric proxy PROMIS depression, physical function, peer relationships, pain interference, and anger scales in pediatric burn patients. Although agreement was moderate to good, assessing proxy-report alone as a surrogate should only be considered when self-report is not possible or practical. Caregivers typically report slightly worse severity of symptoms than children across all domains.

Factors associated with adherence to follow-up care after burn injuries.

INTRODUCTION: In South Africa, burns result in excessive morbidity which can be mitigated via follow-up treatments. This study evaluated factors associated with care retention for after burn injuries. METHODS: A retrospective chart review was performed for twelve months of care at the public burn facility in Kwazulu-Natal, South Africa. All inpatients were eligible, although those who were transferred or died during care were excluded. The primary outcome was return for initial appointment one-week after discharge. The population was analyzed descriptively, and multivariable logistic regression was employed to yield adjusted odds ratios (aOR) with associated 95% confidence intervals (CIs). RESULTS: From 354 patients 310 were analyzed. Of these, 177 (57.47%) were children (<12 years). One third (33.12%) of patients were non-adherent to follow-up (n = 102). In multivariable analysis, children ≤12 years of age were more likely to follow up (aOR = 1.87; 95% CI: 1.07-3.25, p = 0.028), as were those who underwent an operation (aOR = 2.69; 95% CI: 1.47-4.91, p = 0.001). Residing ≥50 km from the health center was associated with lower likelihood of follow up (aOR = 0.52; 95% CI: 0.29-0.93, p = 0.027). CONCLUSION: High follow up attrition suggests the need for enhanced engagement in the high-risk burn population studied, and the identified factors could be leveraged in such programming.

Factors impacting time to surgery and the effect on in-hospital mortality.

OBJECTIVES: Early surgery improves outcomes after burn injuries but is often not available in limited resource settings (LRS), where a more conservative approach is widespread. This study aimed to analyze factors associated with delay in surgical treatment, and the impact on in-hospital mortality. METHODS: All patients with burns treated with surgery between 2016 and 2019 at the Pietermaritzburg Burn Service, in South Africa, were included in this retrospective study. Early surgery was defined as patients who underwent surgery within 7 days from injury. The population was analyzed descriptively and differences between groups were tested using t-test, and χ2 test or Fisher's exact test, as appropriate. Multivariable logistic regression was used to analyze the effect of delay in surgical treatment on in-hospital mortality, after adjustment for confounders. RESULTS: During the study period, 620 patients with burns underwent surgery. Of them, 16% had early surgery. The early surgery group had a median age and TBSA of 11 years (3-35) and 12.0% (5-22) compared to 7 years (2-32) and 6.0% (3-13) in the late surgery group (p=0.45, p<0.001). In logistic regression, female sex [aOR: 3.30 (95% CI: 1.47-7.41)], TBSA% [aOR: 1.09 (95% CI: 1.05-1.12)], and FTB [aOR: 3.21 (95% CI: 1.43-7.18)] were associated with in-hospital mortality, whereas having early surgery was not [aOR: 1.74 (95% CI: 0.76-3.98)]. CONCLUSION: This study found that early surgery was not associated with in-hospital mortality. Independent predictors of in-hospital mortality were female sex, presence of full thickness burn, and larger burn size. Future studies should investigate if burn care capacity in LRS may influence the association between early excision and outcome.

Higher education associated with better national tetanus vaccination coverage: A population-based assessment.

Vaccination coverage among United States (U.S.) adults for tetanus continues to be lower than the national goals. Education has demonstrated a positive impact on vaccination coverage. However, recently there have been outbreaks of vaccine preventable conditions in areas with high college completion rates. This study assessed the relationship between education and tetanus vaccination. Data from the 2016 Behavioral Risk Factor Surveillance System (BRFSS), a self-reported annual survey for non-institutionalized adults in the US from the Centers for Disease Control, was analyzed in 2019. The outcome was up-to-date tetanus vaccination if received within the last 10 years. Education was categorized into 1) grade 11 or less, 2) grade 12/GED, 3) college 1-3 years, and 4) college 4 or more years. Bivariate analyses and multivariable logistic regression were conducted on the analytic sample (n = 417,473) using Stata 15, accounting for weighting and the complex survey design. In 2016, 59.9% of U.S. adults had up-to-date tetanus vaccination. Higher education level was associated with increased odds of up-to-date tetanus vaccination. The highest odds were for those with 4 or more years of college education [aOR = 1.31; 95% (CI: 1.26-1.35)]. Female sex, Black (non-Hispanic), unemployed, not being married, not having insurance or a personal health care provider, and above 45 years of age had lower odds of up-to-date tetanus vaccination. Targeted community specific vaccination education programs for those without tertiary education may help enhance the knowledge and thus the overall vaccination status in the U.S.
