Burn Care in the Street: A Survey of the Current Landscape of Burn Care Provided by Street Medicine Teams.

People experiencing homelessness are at increased risk for serious burn injuries and face additional barriers to care such as inability to perform wound care and difficulty with follow-up. Although not burn-specific, street medicine programs provide direct medical care to people experiencing unsheltered homelessness in their own environment and may be well positioned to bridge this gap in burn care for this population. We conducted a cross-sectional survey to characterize the burn care experience of street medicine teams with providing burn care for people experiencing homelessness. The 60 respondents included 18 (30%) physicians, 15 (25%) nurse practitioners or physician assistants, 15 (25%) registered nurses, and 6 (10%) medical students, and 6 (10%) other team members. The most common reported barriers to care were prior negative experiences with emergency departments, and transportation to burn centers. There was regional variability in frequency of providing burn care, which was reflected in respondent comfort with assessing and treating burns. Burns were most often dressed with daily dressings such as a non-adherent dressing over silver sulfadiazine or bacitracin. Silver-based contact dressings were rarely used. Street medicine teams in the United States are treating burn injuries among people experiencing homelessness, though management practices and experience treating burns was variable. As street medicine programs continue to grow, burn-related education, training, and connections to local burn centers for team members is important. Through strengthened partnerships between burn centers and street medicine teams, these programs may be well positioned to bridge the gap in burn care for people experiencing homelessness.

Management of Vulvovaginal Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis.

Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) is an autoimmune process resulting in painful epidermal sloughing that can involve the vulva and vagina. Current guideline recommendations are based on expert opinion and may not reflect modern management of SJS/TEN in burn centers. We performed a retrospective chart review of 34 female patients treated for SJS/TEN at our burn center from 2015 to 2023. Cases frequently involved the vulva (83.3%) and vagina (56.0%), though pelvic examination often was limited. For eight patients with confirmed vulvovaginal lesions, there were no direct sequelae of SJS/TEN requiring intervention. In the modern era of SJS/TEN management in burn centers, interventions such as steroids may not be needed.

Pediatric Burn Unit Admission is Associated with School Holidays and Lower Home Childhood Opportunity Level.

Burn injury can have profound detrimental effects on quality of life and mental health of children. We collected demographics, burn etiology, burn date, and home zip code for pediatric patients admitted to our burn unit from 2016-2023. Age, burn date, and etiology of burn were used to assess temporal and mechanistic patterns of injury for pre-school-age and school-age children. Home zip code was used to determine each child's home Childhood Opportunity Index score, which is composed of sub-domains for Education, Health & Environment, and Social & Economic. We calculated the odds-ratio for odds of pediatric burn admission for each COI sub-domain quintile, using very high opportunity neighborhoods as the reference. Scald was the prevailing burn etiology (64%). In school-age children, July was the month with the most burn injuries (19%), attributable to firework injuries. School-age children were also more likely to be injured in a week without classroom instruction (p<0.001). There was a dose-response relationship between Childhood Opportunity Index and odds of burn admission, with the greatest odds of burn admission observed for children from very low educational opportunity areas (OR 5.21, 95% CI 3.67-7.39). These findings support interventions for burn prevention such as increased education about the dangers of fireworks, addressing inequities in access to childcare and extracurricular activities, and reducing the default water heater temperatures in multi-unit dwellings.

Food Security: An Unmet Need in Outpatient Burn Care.

Nutrition is paramount for wound healing after burn injury. With rising food prices and time off work due to burn injuries, access to adequate nutrition may be a significant financial stressor. We asked patients at an outpatient burn clinic to complete the Household Food Security Module, which queries about food security over the preceding 12 months. Demographics and burn characteristics were abstracted from the medical record. We assessed the overall prevalence of food insecurity, risk factors for food insecurity, and potential effects of food insecurity on nutritional status and wound healing time. Wound healing time was assessed via Cox regression while adjusting for burn depth, total body surface area burned, and diabetes. Over 40% of participants reported experiencing food insecurity; it was more common in patients who preferred Spanish language (p=0.014) or were unemployed (p=0.049). Just over half of participants experiencing food insecurity were using any food assistance resources. Among patients more than 30 days from burn injury, patients who were food insecure had larger burns (p=0.01). Experience of food insecurity was not associated presence of malnutrition on nutrition-focused physical exam (p=0.47). Wound healing time for burns managed in the outpatient setting was associated with burn depth (p<0.001), but not food insecurity (p=0.95), burn size (p=0.17), or diabetes (p=0.14). Although food insecurity did not result in malnutrition or negatively impact wound healing time, it is important for providers to routinely screen for food insecurity due to increased nutritional requirements and loss of wages after burn injury.

Analyzing Burn-Related Content on Social Media Platforms: A Study of Creator Types, Content Focus, and Engagement Metrics.

Social media offers a readily available, cost-effective way for medical experts to disseminate knowledge and shape public health outcomes but also allows for the spread of misinformation. This study aims to analyze burn-related material on social media by creator, content type, and engagement. Facebook, TikTok, and X (formerly Twitter) were queried with the following search terms: "burn," "burn injury," "burn recovery," and "burn treatment." Identified accounts were then manually screened for relevance. Year of creation and engagement metrics were collected. Accounts were categorized by content and creator type. Data was reported using descriptive statistics and visualized graphically to explore trends. Our search yielded 434 profiles, 234 of which met inclusion criteria. TikTok had the most engagement at a median of 43,500 followers per account, with 38.3% of accounts focusing on individual experiences of burn survivors primarily on personal accounts (48.3%). In contrast, content on Facebook was related to promotion of medical services (36.9%), where the most represented creator type was medical centers (33.6%). Nonprofits made up 40.4% of accounts on Twitter/X and more than a third of the content focused on patient advocacy, support, or burn prevention (36.5%). Important topics like burn education, prevention, and social support are lacking on major social media platforms. Engagement from burn care organizations and burn experts on social media is necessary. The findings of this study may guide advocates in the burn community on where and how to disseminate information in social media.

Clinical Practice Guideline: Age-Related Hearing Loss Executive Summary.

OBJECTIVE: Age-related hearing loss (ARHL) is a prevalent but often underdiagnosed and undertreated condition among individuals aged 50 and above. It is associated with various sociodemographic factors and health risks including dementia, depression, cardiovascular disease, and falls. While the causes of ARHL and its downstream effects are well defined, there is a lack of priority placed by clinicians as well as guidance regarding the identification, education, and management of this condition. PURPOSE: The purpose of this clinical practice guideline is to identify quality improvement opportunities and provide clinicians trustworthy, evidence-based recommendations regarding the identification and management of ARHL. These opportunities are communicated through clear actionable statements with an explanation of the support in the literature, the evaluation of the quality of the evidence, and recommendations on implementation. The target patients for the guideline are any individuals aged 50 years and older. The target audience is all clinicians in all care settings. This guideline is intended to focus on evidence-based quality improvement opportunities judged most important by the Guideline Development Group (GDG). It is not intended to be a comprehensive, general guide regarding the management of ARHL. The statements in this guideline are not intended to limit or restrict care provided by clinicians based on their experience and assessment of individual patients. ACTION STATEMENTS: The GDG made strong recommendations for the following key action statements (KASs): (KAS 4) If screening suggests hearing loss, clinicians should obtain or refer to a clinician who can obtain an audiogram. (KAS 8) Clinicians should offer, or refer to a clinician who can offer, appropriately fit amplification to patients with ARHL. (KAS 9) Clinicians should refer patients for an evaluation of cochlear implantation candidacy when patients have appropriately fit amplification and persistent hearing difficulty with poor speech understanding. The GDG made recommendations for the following KASs: (KAS 1) Clinicians should screen patients aged 50 years and older for hearing loss at the time of a health care encounter. (KAS 2) If screening suggests hearing loss, clinicians should examine the ear canal and tympanic membrane with otoscopy or refer to a clinician who can examine the ears for cerumen impaction, infection, or other abnormalities. (KAS 3) If screening suggests hearing loss, clinicians should identify sociodemographic factors and patient preferences that influence access to and utilization of hearing health care. (KAS 5) Clinicians should evaluate and treat or refer to a clinician who can evaluate and treat patients with significant asymmetric hearing loss, conductive or mixed hearing loss, or poor word recognition on diagnostic testing. (KAS 6) Clinicians should educate and counsel patients with hearing loss and their family/care partner(s) about the impact of hearing loss on their communication, safety, function, cognition, and quality of life. (KAS 7) Clinicians should counsel patients with hearing loss on communication strategies and assistive listening devices. (KAS 10) For patients with hearing loss, clinicians should assess if communication goals have been met and if there has been improvement in hearing-related quality of life at a subsequent health care encounter or within 1 year. The GDG offered the following KAS as an option: (KAS 11) Clinicians should assess hearing at least every 3 years in patients with known hearing loss or with reported concern for changes in hearing.

Navigating Scar Care: An Evaluation of Scar Treatment Patient Education Materials.

While patient education materials (PEMs) across various specialties have been reported as being too difficult to read, the quality and understandability of PEMs related to scar management have not been assessed. In this study, we report the breadth of scar management interventions and readability of online PEMs authored by academic societies and university hospitals. Websites of academic medical societies and university hospitals with scar revision PEMs were assessed for relevance. PEM readability was assessed via Flesch Reading Ease, Flesch-Kincaid Grade Level, and Gunning-Fox Index scores. Understandability and actionability were evaluated using the Patient Education Material Assessment Tool (PEMAT). A total of 26 scar revision PEMs met the inclusion criteria. The most commonly mentioned scar management interventions were scar revision surgery (73%) and laser scar revision (70%), with minimal emphasis on noninvasive methods like scar massage or sun protection. Readability analysis yielded a mean Flesch reading level of 8.8. Overall, PEMAT understandability of online scar treatment PEMs was moderate, with a median of 76.0% (IQR 71.5%-80.5%). PEMs from all specialties and institution types were lacking in actionability, with median actionability of 40.8% (IQR 38.1%-60.0%). Online scar revision PEMs included a wide breadth of scar management interventions; however, the least costly interventions, such as sun protection and scar massage, were not commonly included. PEMs for scar management could be improved by simplifying language, including visual aids, and including checklists or specific steps, patients can take to take action on scar management interventions.

The sensitivity of limited-sequence magnetic resonance imaging in identifying pediatric cervical spine injury: A Western Pediatric Surgery Research Consortium multicenter retrospective cohort study.

INTRODUCTION: Clinical clearance of a child's cervical spine after trauma is often challenging because of impaired mental status or an unreliable neurologic examination. Magnetic resonance imaging (MRI) is the criterion standard for excluding ligamentous injury in children but is constrained by long image acquisition times and frequent need for anesthesia. Limited-sequence magnetic resonance imaging (LSMRI) is used in evaluating the evolution of traumatic brain injury and may also be useful for cervical spine clearance while potentially avoiding the need for anesthesia. The purpose of this study was to assess the sensitivity and negative predictive value of LSMRI as compared with criterion standard full-sequence MRI as a screening tool to rule out clinically significant ligamentous cervical spine injury. METHODS: We conducted a 10-center, 5-year retrospective cohort study (2017-2021) of all children (0-18 years) with a cervical spine MRI after blunt trauma. Magnetic resonance imaging images were rereviewed by a study pediatric radiologist at each site to determine if the presence of an injury could be identified on limited sequences alone. Unstable cervical spine injury was determined by study neurosurgeon review at each site. RESULTS: We identified 2,663 children younger than 18 years who underwent an MRI of the cervical spine with 1,008 injuries detected on full-sequence studies. The sensitivity and negative predictive value of LSMRI were both >99% for detecting any injury and 100% for detecting any unstable injury. Young children (younger than 5 years) were more likely to be electively intubated or sedated for cervical spine MRI. CONCLUSION: Limited-sequence magnetic resonance imaging is reliably detects clinically significant ligamentous injury in children after blunt trauma. To decrease anesthesia use and minimize MRI time, trauma centers should develop LSMRI screening protocols for children without a reliable neurologic examination. LEVEL OF EVIDENCE: Diagnostic Test/Criteria; Level III.

Injury Pattern Analysis to Optimize Burn Injury Prevention in the Unhoused Community.

Unhoused patients are an overrepresented group in burn injury, and are a uniquely vulnerable population. Current research focuses on the consequences of homelessness on burn outcomes, with little known about the specific circumstances and behaviors leading to burn injury that may represent specific targets for injury prevention efforts. The burn registry at an urban regional burn center was queried for burn admissions in unhoused adults from 2019 to 2022. Registry data pulled included demographics, urine toxicology, mechanism of injury, and injury subjective history. Subjective injury history was reviewed to determine more specific injury circumstances and activities during which accidental burns occurred. Demographic and mechanistic trends in burn admissions were explored via descriptive statistics. Among 254 admissions for burns from the unhoused community, 58.1% of patients were positive for stimulants on admission. Among accidental injuries (69.7%), common circumstances included preparing food or beverages, cooking or using methamphetamine, smoking cannabis or tobacco, bonfires, and candles. A specific common circumstance was lighting a cigarette while handling accelerants (6.7%). Interventions for stimulant abuse, as well as outreach efforts to educate unhoused patients about situational awareness, safe handling of accelerants, safe smoking practices, and safe cooking practices, may be effective tools in reducing burn admissions in this vulnerable population.

Trends and variation in cervical spine imaging utilization across children's hospitals for pediatric trauma.

BACKGROUND: Cervical spine (c-spine) evaluation is a critical component in trauma evaluation, and although several pediatric c-spine evaluation algorithms have been developed, none have been widely implemented. Here, we assess rates of c-spine imaging use across children's hospitals, specifically temporal trends in imaging use, variation across hospitals in imaging used, and timing of magnetic resonance imaging in admitted patients. METHODS: Data from the Children's Hospital Associations Pediatric Health Information System were abstracted from 2015 to 2020. Patients younger than 18 years seen in the emergency department with an International Classification of Diseases, Tenth Revision , code indicative of trauma and c-spine plain radiograph or computed tomography (CT) in the emergency department were included. Data visualization and descriptive statistics were used to assess rates of imaging use by age, year, hospital, injury severity, and day of service. Changes in rates of imaging use over time were evaluated via simple linear regression. RESULTS: Across 25,238 patient encounters at 35 children's hospitals, there was an increase in use of c-spine CT from 2015 to 2020 (28.5-36.5%). There was substantial interinstitutional variation in rates of use of plain radiographs versus CT for initial evaluation of the c-spine across all age groups. Magnetic resonance imaging was obtained more than 3 days after admission in 31.5% of intensive care patients who received this imaging. CONCLUSION: Increasing use of CT, substantial interinstitutional variation in rates of use of plain radiographs versus CT, and heterogenous timing of magnetic resonance imaging for evaluation of the pediatric c-spine demonstrate the growing need for development and implementation of an age-specific c-spine evaluation algorithm to guide judicious use of diagnostic resources. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

The development of laying hen locomotion in 3D space is affected by early environmental complexity and genetic strain.

Adult laying hens are increasingly housed in spatially complex systems, e.g., non-cage aviaries, where locomotion between elevated structures can be challenging for these gallinaceous birds. This study assessed the effect of early environmental complexity on spatial skills in two genetic strains. Brown (B) and white (W) feathered birds were raised in: Conventional cages with minimal complexity (Conv) or rearing aviaries with low (Low), intermediate (Mid), or high complexity (High). Birds from each housing treatment were challenged at three different time points in three different, age-appropriate vertical spatial tasks. Whites performed better than brown birds in all tests regardless of rearing environment. In chicks, test performance was predominantly explained by variation between replicates and differences in motivation for test participation. Treatment effects were seen in pubertal birds (pullets), with pullets from aviaries performing better than those from Conv. White High pullets performed better than white Mid or Low, an effect that was not found in browns. Pullets preferred to use a ramp to move downwards, but only when ramps had previously been experienced and when the ramp was not too steep. Overall, early environmental complexity affected spatial skills of laying hen pullets with stronger effects in white than brown feathered birds.

Children with Rolandic epilepsy have micro- and macrostructural abnormalities in white matter constituting networks necessary for language function.

INTRODUCTION: Self-limited epilepsy with centrotemporal spikes is a transient developmental epilepsy with a seizure onset zone localized to the centrotemporal cortex that commonly impacts aspects of language function. To better understand the relationship between these anatomical findings and symptoms, we characterized the language profile and white matter microstructural and macrostructural features in a cohort of children with SeLECTS. METHODS: Children with active SeLECTS (n = 13), resolved SeLECTS (n = 12), and controls (n = 17) underwent high-resolution MRIs including diffusion tensor imaging sequences and multiple standardized neuropsychological measures of language function. We identified the superficial white matter abutting the inferior rolandic cortex and superior temporal gyrus using a cortical parcellation atlas and derived the arcuate fasciculus connecting them using probabilistic tractography. We compared white matter microstructural characteristics (axial, radial and mean diffusivity, and fractional anisotropy) between groups in each region, and tested for linear relationships between diffusivity metrics in these regions and language scores on neuropsychological testing. RESULTS: We found significant differences in several language modalities in children with SeLECTS compared to controls. Children with SeLECTS performed worse on assessments of phonological awareness (p = 0.045) and verbal comprehension (p = 0.050). Reduced performance was more pronounced in children with active SeLECTS compared to controls, namely, phonological awareness (p = 0.028), verbal comprehension (p = 0.028), and verbal category fluency (p = 0.031), with trends toward worse performance also observed in verbal letter fluency (p = 0.052), and the expressive one-word picture vocabulary test (p = 0.068). Children with active SeLECTS perform worse than children with SeLECTS in remission on tests of verbal category fluency (p = 0.009), verbal letter fluency (p = 0.006), and the expressive one-word picture vocabulary test (p = 0.045). We also found abnormal superficial white matter microstructure in centrotemporal ROIs in children with SeLECTS, characterized by increased diffusivity and fractional anisotropy compared to controls (AD p = 0.014, RD p = 0.028, MD p = 0.020, and FA p = 0.024). Structural connectivity of the arcuate fasciculus connecting perisylvian cortical regions was lower in children with SeLECTS (p = 0.045), and in the arcuate fasciculus children with SeLECTS had increased diffusivity (AD p = 0.007, RD p = 0.006, MD p = 0.016), with no difference in fractional anisotropy (p = 0.22). However, linear tests comparing white matter microstructure in areas constituting language networks and language performance did not withstand correction for multiple comparisons in this sample, although a trend was seen between FA in the arcuate fasciculus and verbal category fluency (p = 0.047) and the expressive one-word picture vocabulary test (p = 0.036). CONCLUSION: We found impaired language development in children with SeLECTS, particularly in those with active SeLECTS, as well as abnormalities in the superficial centrotemporal white matter as well as the fibers connecting these regions, the arcuate fasciculus. Although relationships between language performance and white matter abnormalities did not pass correction for multiple comparisons, taken together, these results provide evidence of atypical white matter maturation in fibers involved in language processing, which may contribute to the aspects of language function that are commonly affected by the disorder.

Identifying Populations at Risk for Difficulty Managing Emotions and Social Interactions After Burn Injury.

There has been conflicting data on the relationship between burn severity and psychological outcomes. The present study aims to characterize the baseline psychosocial disposition of adults attending outpatient burn clinic at a large urban safety net hospital, as well as the impact of clinical course on self-reported psychosocial well-being. Adult patients attending outpatient burn clinic completed survey questions from the National Institutes of Health Patient-Reported Outcomes Measurement Information System Managing Chronic Conditions: Self-Efficacy for Managing Social Interactions (SEMSI-4) and Managing Emotions (SEME). Sociodemographic variables were collected from surveys and retrospective chart review. Clinical variables included total body surface area burned, initial hospital length of stay, surgical history, and days since injury. Poverty level was estimated by U.S. census data using patient's home ZIP code. Scores on SEME-4 and SEMSI-4 were compared to the population mean by one-sample T-test, and independent variables evaluated for associations with managing emotions and social interactions by Tobit regression while adjusting for demographic variables. The 71 burn patients surveyed had lower scores in SEMSI-4 (mean = 48.0, P = .041) but not SEME-4 (mean = 50.9, P = .394) versus the general population. Marital status and neighborhood poverty level were associated with SEMSI-4, while length of stay and % total body surface area burned were associated with SEME-4. Patients who are single or from poorer neighborhoods may have difficulty interacting with their environment after burn injury and need extra social support. Prolonged hospitalization and increased severity of burn injury may have more impact on emotional regulation; these patients may benefit from psychotherapy during recovery.

Neighborhood deprivation and childhood opportunity indices are associated with violent injury among children in Los Angeles County.

BACKGROUND: Previous research has demonstrated mixed relationships between individual neighborhood socioeconomic factors and incidences of violence, such as poverty level, population density, and income inequality. We used the Childhood Opportunity Index and Area Disadvantage Index to evaluate the relationship between neighborhood characteristics and the number of incidents of violence among children across the zip codes of Los Angeles (LA) County. METHODS: We performed a retrospective cross-sectional study of children younger than 18 years from 2017 to 2019 who were entered in the LA County Trauma and Emergency Medicine Information System registry with violent mechanisms of injury, including gunshot, stabbing, or assault. Mechanisms classified as self-inflicted injuries were excluded from the study. The number of incidences of violent mechanism per 100,000 persons younger than 18 years for each zip code was calculated using population data from the US Census American Community Survey 5-Year estimates from 2019. The incidences of violence per capita younger than 18 years for each zip code was compared with the zip code Area Deprivation Index and Childhood Opportunity Index using logistic regression models. RESULTS: There were 6,791 trauma activations in LA County over the study period, 12.8% (n = 866) of which were due to violence. The mean prevalence of pediatric violent mechanism of injury per zip code was 4 cases per 100,000 persons younger than 18 years. Most injuries were the result of firearms (n = 345 [60.4%]) and occurred among Hispanic/Latino children (n = 362 [57.1%]). There were significantly greater rates of violent injury among children from highest disadvantage (odds ratio, 8.84) and lowest opportunity (odds ratio, 42.48) zip codes. CONCLUSION: Children living in high disadvantage or low opportunity zip codes had greater rates of violent injury. Further study of neighborhood factors is needed to develop targeted effective interventions to reduce violent injuries among children living in low opportunity areas. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

Effects of Swaddling During Bottle Feeding in Preterm Infants.

BACKGROUND: Preterm infants have immature oral feeding skills, affecting length of hospital stay and long-term feeding outcomes. Swaddling has positive effects on pain and stress responses, state regulation, and physiological stability in preterm infants in the neonatal intensive care unit (NICU). Swaddling during bottle feeding may support preterm infant behavioral organization and oral feeding skills. Swaddling is used inconsistently during feeding in the NICU and has not been critically examined for effects on bottle feeding performance in preterm infants. PURPOSE: To examine the effects of swaddling on bottle feeding quality and efficiency in preterm infants. METHODS: A convenience sample of 30 infants born before 34 weeks of gestation was selected in an urban level IV NICU. Using an experimental, randomized crossover design, each infant was swaddled for one feeding and unswaddled for one feeding. Feeding efficiency was measured by rate and volume consumed. Feeding quality was examined by the Early Feeding Skills Assessment and frequency of physiological changes. Data were analyzed using dependent t tests and Wilcoxon signed rank test. RESULTS: When swaddled, participants demonstrated significantly better scores on all related subtests of the Early Feeding Skills Assessment ( P ≤ .001). Infants demonstrated no difference in frequency of bradycardia or oxygen desaturations greater than 4 seconds. No significant differences were found in feeding efficiency outcomes. IMPLICATIONS FOR PRACTICE AND RESEARCH: Swaddling can be used in the NICU to improve bottle feeding quality in preterm infants. Future investigation is needed on long-term effects of swaddling during bottle feeding on feeding performance, weight gain, and length of stay.

Peer Support Groups: Identifying Disparities to Improve Participation.

Disparities in psychosocial outcomes after burn injury exist in patients from racial or ethnic minority groups in the United States. Peer support groups can help patients with many psychosocial aspects of recovery from burns; however, access to such support among patients of racial and ethnic minority or low socioeconomic groups are unknown. The present study examined participation rates in outpatient peer support within this patient population. Patients attending outpatient clinic at an urban safety-net hospital and regional burn center with a majority minority patient population were asked about participation in burn survivor group, interest in joining a group, and given validated survey questions about managing emotions and social interactions since injury. Current or past participation in peer support was low (4.2%), and 30.3% of patients not already in support group were interested in joining. Interest in future participation in peer support was highest among Hispanic patients (37.0%) and lowest among Black patients (0%). Logistic regression models demonstrated that increased total body surface area burned, hospital length of stay, and need for surgical intervention were associated with interest in joining or having joined a peer support group. Effectiveness of management of emotions and social interactions were not associated with interest in joining peer support in the future. These findings demonstrate a considerable difference between levels of interest and participation in peer support within this population. Improving access to and education about benefits of peer support in underresourced communities may help to address the variation in psychosocial outcomes of patients across racial or ethnic minority groups recovering from burns.

Influence of middle hepatic vein resection during right or left hepatectomy on post hepatectomy outcomes.

Backgrounds/Aims: Middle hepatic vein (MHV) is usually preserved as a part of the right or left hepatectomy in order preserve the venous outflow of remnant liver. The aim of this study was to evaluate if resection of MHV could influence post-resection outcomes of standard right or left hepatectomy. Methods: Patients who underwent standard right or left hepatectomy between January 2015 and December 2019 were included. Anatomical remnant liver volumes were measured retrospectively using the Hermes workstation (Hermes Medical Solutions AB, Stockholm, Sweden). Uni- and multi-variate analyses were performed to assess the difference in outcomes of those with preservation of MHV and those without preservation. Results: A total of 144 patients were included. Right hepatectomy was performed for 114 (79.2%) and left hepatectomy was performed for 30 (20.8%) patients. MHV was resected for 13 (9.0%) in addition to the standard right or left hepatectomy. Median remnant liver volume was significantly higher in the MHV resected group (p < 0.01). There was no significant difference in serum level of bilirubin, international normalized ratio, alanine aminotransferase, creatinine on postoperative day 1, 3, 5, or 10, ≥ grade IIIa complications (p = 0.44), or 90-day mortality (p = 0.41). On multivariable analysis, resection of the MHV did not influence the incidence of post hepatectomy liver failure (p = 0.52). Conclusions: Resection of the MHV at standard right or left hepatectomy did not have a negative impact on postoperative outcomes of patients with adequate remnant liver volume.

Coincidence Anticipation Timing Responses with Head Tracking and Eye Tracking.

BACKGROUND: Head tracking movements are common in interceptive tasks. The benefits of these movements are unclear. The purpose of this study was to compare coincidence anticipation timing (CAT) responses for a simulated approaching object when the eyes were used in tracking the object and when the head was used in tracking the object.METHODS: A total of 29 subjects participated. A Bassin Anticipation Timer consisting of a track of sequentially illuminated lights was used to simulate an approaching object at velocities of 223 cm · s-1 to 894 cm · s-1. Each velocity was used 10 times under 2 conditions. In one condition, subjects were told to turn the eyes with the stimulus. In the other condition, subjects viewed the stimulus through apertures and were told to turn the head with the stimulus. Subjects pushed a button to coincide with illumination of the final light on the track.RESULTS: Signed CAT errors, unsigned CAT errors, and variable CAT errors were compared between the head movement (HM) and eye movement (EM) conditions. No significant differences were noted for the signed errors (mean signed error at 894 cm · s-1; 10.3 ± 75.4 ms (HM), -16.1 ± 51.0 ms (EM). However, the unsigned and variable errors were significantly larger at some stimulus velocities in the head movement condition [mean unsigned error at 894 cm · s-1: 82.6.0 ± 45.9 ms (HM), 59.0 ± 22.4 ms (EM); mean variable error at 894 cm · s-1; 78.0 ± 37.8 ms (HM), 49.2 ± 17.1ms (EM)].DISCUSSION: Head movement did not result in improved CAT performance compared to eye movements. Further work will be required to determine whether these results are generalizable to situations where head tracking is required but apertures are not worn.Ross E, Kinney M, Fogt N.
