Expanding opportunities for chronic disease prevention for Hispanics: the Better Together REACH program in Pennsylvania.

Background: Hispanics in Lebanon and Reading, Pennsylvania, experience high levels of socioeconomic and health disparities in risk factors for chronic disease. In 2018, our community-academic coalition "Better Together" received a Racial and Ethnic Approaches to Community Health (REACH) award to improve healthy lifestyles. This report describes our work-in-progress and lessons learned to date from our REACH-supported initiatives in Lebanon and Reading. Methods: For the past 4 years, our coalition has leveraged strong community collaborations to implement and evaluate culturally-tailored practice- and evidence-based activities aimed at increasing physical activity, healthy nutrition, and community-clinical linkages. This community case report summarizes the context where our overall program was implemented, including the priority population, target geographical area, socioeconomic and health disparities data, community-academic coalition, conceptual model, and details the progress of the Better Together initiative in the two communities impacted. Results: To improve physical activity, we are: (1) creating new and enhancing existing trails connecting everyday destinations through city redesigning and master planning, (2) promoting outdoor physical activity, (3) increasing awareness of community resources for chronic disease prevention, and (4) supporting access to bikes for youth and families. To improve nutrition, we are: (1) expanding access to locally-grown fresh fruit and vegetables in community and clinical settings, through the Farmers Market Nutrition Program to beneficiaries of the Women, Infants, and Children (WIC) program and the Veggie Rx to patients who are at risk for or have diabetes, and (2) providing bilingual breastfeeding education. To enhance community-clinical linkages, we are training bilingual community health workers to connect at-risk individuals with diabetes prevention programs. Conclusions: Intervening in areas facing high chronic disease health disparities leads us to develop a community-collaborative blueprint that can be replicated across Hispanic communities in Pennsylvania and the United States.

Implementing Locally Tailored Strategies to Promote Redemption of Farmers' Market Nutrition Program Vouchers Among WIC Participants in Central Pennsylvania.

The Pennsylvania Farmers' Market Nutrition Program (FMNP) provides vouchers to participants of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) to purchase locally grown fruits, vegetables (F&V), and herbs every year from June to November. Voucher redemption is suboptimal among WIC participants in Lebanon County, a community with high numbers of low-income and Hispanic families. Supported by a Racial and Ethnic Approaches to Community Health (REACH) award, our community-academic coalition partnered with the local WIC provider to implement locally tailored strategies to promote redemption of FMNP vouchers. In 2019, we surveyed FMNP participants (n = 100) to examine opportunities for improved voucher redemption. Increasing sites for voucher use (47%) and a larger variety of F&V (27%) were the most commonly selected improvements participants identified. Participants also supported improvements to increase awareness of available seasonal produce (14%), text/phone reminders to redeem vouchers (13%), and having recipes to cook meals with FMNP-approved F&V (12%). These findings led us to implement a weekly, Farm-to-WIC "grab bag" program in 2020/2021. We partnered with a local farmer to offer a variety of FMNP-approved produce in $3 and $6 grab bags at the local WIC provider. Each grab bag included healthy recipes using the included produce. In 2021, we launched a text/phone reminder intervention to encourage voucher redemption among FMNP participants (n = 57). Our work demonstrates the value of community-academic partnerships to identify and implement feasible strategies that are responsive to local needs as well as supporting existing programs providing greater access to affordable produce.

ICG angiography predicts burn scarring within 48 h of injury in a porcine vertical progression burn model.

The current standard of care in determining the need to excise and graft a burn remains with the burn surgeon, whose clinical judgment is often variable. Prior work suggests that minimally invasive perfusion technologies are useful in burn prognostication. Here we test the predictive capabilities of Laser Doppler Imaging (LDI) and indocyanine green dye (ICG) angiography in the prediction of burn scarring 28 days after injury using a previously validated porcine burn model that shows vertical progression injury. Twelve female Yorkshire swine were burned using a 2.5 × 2.5 cm metal bar at variable temperature and application times to create distinct burn depths. Six animals (48 injuries total) each were analyzed with LDI or ICG angiography at 1, 24, 48, and 72 h following injury. A linear regression was then performed correlating perfusion measurements against wound contraction at 28 days after injury. ICG angiography showed a peak linear correlate (r(2)) of .63 (95% CI .34 to .92) at 48 h after burn. This was significantly different from the LDI linear regression (p < .05), which was measured at r(2) of .20 (95% CI .02 to .39). ICG angiography linear regression was superior to LDI at all timepoints. Findings suggest that ICG angiography may have significant potential in the prediction of long-term burn outcomes.

Indocyanine green dye angiography accurately predicts survival in the zone of ischemia in a burn comb model.

INTRODUCTION: Surgical evaluation of burn depth is performed via clinical observation, with only moderate reliability. While perfusion analysis has been proposed to enhance accuracy, no perfusion study has attempted to predict burn extension into the area of ischemia surrounding the original insult. We examined whether laser Doppler imaging (LDI) and indocyanine green (ICG) angiography predicted survival in the zone of ischemia in a porcine hot comb burn model. METHODOLOGY: Six full-thickness wounds were created on 5 female Yorkshire swine using a validated porcine hot comb burn model. 4 full-thickness burns were created separated by 3 unburned interspaces that represent the zone of ischemia. The interspaces between each comb burn were monitored using LDI and ICG Angiography at 1, 4, 24, and 48 h after burn. Interspace survival was assessed via gross observation and blinded histological readings 7 days after injury. RESULTS: ICG Angiographic assessments of burn perfusion were significantly different in viable vs. non-viable interspace perfusion at 1 h, 4 h, and 48 h. Temporal plotting of a trend-line derived from quantitative perfusion measurements rendered two distinct graphs, allowing for the derivation of a predictive algorithm to separate viable and non-viable interspaces. LDI revealed no such prognostic trend. CONCLUSION: Results from a validated porcine burn comb model suggest that ICG angiography has significant potential in the prediction of burn progression early after burn. However, the full potential of this technology cannot be determined until completion of clinical trials.

Validation of a vertical progression porcine burn model.

A major potential goal of burn therapy is to limit progression of partial- to full-thickness burns. To better test therapies, the authors developed and validated a vertical progression porcine burn model in which partial-thickness burns treated with an occlusive dressing convert to full-thickness burns that heal with scarring and wound contraction. Forty contact burns were created on the backs and flanks of two young swine using a 150 g aluminum bar preheated to 70°C, 80°C, or 90°C for 20 or 30 seconds. The necrotic epidermis was removed and the burns were covered with a polyurethane occlusive dressing. Burns were photographed at 1, 24, and 48 hours as well as at 7, 14, 21, and 28 days postinjury. Full-thickness biopsies were obtained at 1, 4, 24, and 48 hours as well as at 7 and 28 days. The primary outcomes were presence of deep contracted scars and wound area 28 days after injury. Secondary outcomes were depth of injury, reepithelialization, and depth of scars. Data were compared across burn conditions using analysis of variance and χ(2) tests. Eight replicate burns were created with the aluminum bar using the following temperature/contact-time combinations: 70/20, 70/30, 80/20, 80/30, and 90/20. The percentage of burns healing with contracted scars were 70/20, 0%; 70/30, 25%; 80/20, 50%; 80/30, 75%; and 90/20, 100% (P = .05). Wound areas at 28 days by injury conditions were 70/20, 8.1 cm(2); 70/30, 7.8 cm(2); 80/20, 6.6 cm(2); 80/30, 4.9 cm(2); and 90/20, 4.8 cm(2) (P = .007). Depth of injury judged by depth of endothelial damage for the 80/20 and 80/30 burns at 1 hour was 36% and 60% of the dermal thickness, respectively. The depth of injury to the endothelial cells 1 hour after injury was inversely correlated with the degree of scar area (Pearson's correlation r = -.71, P < .001). Exposure of porcine skin to an aluminum bar preheated to 80°C for 20 or 30 seconds results initially in a partial-thickness burn that when treated with an occlusive dressing progresses to a full-thickness injury and heals with significant scarring and wound contracture.

Closing the Gap: cultural safety in Indigenous health education.

The challenge for the future is to embrace a new partnership aimed at closing the gap between Indigenous and non-Indigenous Australians on life expectancy, educational achievement and employment opportunities. Significant improvements in contemporary Indigenous health care can be achieved through culturally safe health education programs for Indigenous students. However, while participation rates of Australian Indigenous students in the higher education sector are increasing, attrition rates are markedly higher than those of the general student population. This paper focuses on a unique degree program that is offered exclusively to Indigenous students in the field of mental health in the School of Nursing, Midwifery and Indigenous Health, Charles Sturt University. This qualitative exploratory study aimed to identify strategies that were especially helpful in sustaining students in the program and to identify and address barriers to the retention of students, to empower students to better prepare for the university environment and to inform academics within the course about areas that could be improved to provide a more culturally safe learning environment. The first stage of the study utilised focus group interviews with 36 Indigenous students across all three years of the program. The findings of the study addressing the issues of culturally appropriate pedagogy, curricula and cultural safety in the mental health degree program are discussed.
