Peer Education as a Tool to Improve Health Knowledge for People Who Are Incarcerated: A Secondary Analysis of Data From the Indiana Peer Education Program ECHO.

Considerable health inequities occur among people who are incarcerated, with ripple effects into broader community health. The Indiana Peer Education Program uses the Extension for Community Health Outcomes Extension for Community Healthcare Outcomes (ECHO) model to train people who are incarcerated as peer health educators. This analysis sought to evaluate the effectiveness of this program and explore emergent themes not covered in survey instruments. Survey data for both peer educators and their students were assessed using multivariate regression. Qualitative data were used to triangulate survey findings and explore additional themes via thematic analysis. Students showed improvements in knowledge scores and postrelease behavior intentions; peer educators improved in knowledge, health attitudes, and self-efficacy. Qualitative data affirmed survey findings and pointed toward peer educators acquiring expertise in the content they teach, and how to teach it, and that positive results likely expand beyond participants to others in prison, their families, and the communities to which they return. Though preliminary, the results confirm an earlier analysis of the New Mexico Peer Education Program ECHO, adding to the evidence that training individuals who are incarcerated as peer educators on relevant public health topics increases health knowledge and behavior intentions and likely results in improvements in personal and public health outcomes.

Manuka honey modulates the release profile of a dHL-60 neutrophil model under anti-inflammatory stimulation.

Manuka honey, a wound treatment used to eradicate bacteria, resolve inflammation, and promote wound healing, is a current focus in the tissue engineering community as a tissue template additive. However, Manuka honey's effect on neutrophils during the inflammation-resolving phase has yet to be examined. This study investigates the effect of 0.5% and 3% Manuka honey on the release of cytokines, chemokines, and matrix-degrading enzymes from a dHL-60 neutrophil model in the presence of anti-inflammatory stimuli (TGF-ß, IL-4, IL-4 +IL-13). We hypothesized that Manuka honey would reduce the output of pro-inflammatory signals and increase the release of anti-inflammatory signals. The results of this study indicate that 0.5% honey significantly increases the release of CXCL8/IL-8, CCL2/MCP-1, CCL4/MIP-1ß, CCL20/MIP-3α, IL-4, IL-1ra, and FGF-13 while reducing Proteinase 3 release in the anti-inflammatory-stimulated models. However, 3% honey significantly increased the release of TNF-α and CXCL8/IL-8 while reducing the release of all other analytes. We replicated a subset of the most notable findings in primary human neutrophils, and the consistent results indicate that the HL-60 data are relevant to the performance of primary cells. These findings demonstrate the variable effects of Manuka honey on the release of cytokines, chemokines, and matrix-degrading enzymes of this model of neutrophil anti-inflammatory activity. This study reinforces the importance of tailoring the concentration of Manuka honey in a wound or tissue template to elicit the desired effects during the inflammation-resolving phase of wound healing. Future in vivo investigation should be undertaken to translate these results to a physiologically-relevant wound environment.

The Effect of Manuka Honey on dHL-60 Cytokine, Chemokine, and Matrix-Degrading Enzyme Release under Inflammatory Conditions.

A large body of in vivo and in vitro evidence indicates that Manuka honey resolves inflammation and promotes healing when applied topically to a wound. In this study, the effect of two different concentrations (0.5% and 3% v/v) of Manuka honey on the release of cytokines, chemokines, and matrix-degrading enzymes from neutrophils was examined using a differentiated HL-60 cell line model in the presence of inflammatory stimuli. The results indicate that 0.5% honey decreased TNF-α, IL-1ß, MIP-1α, MIP-1ß, IL-12 p70, MMP-9, MMP-1, FGF-13, IL-1ra, and IL-4 release, but increased MIP-3α, Proteinase 3, VEGF, and IL-8 levels. In contrast, 3% honey reduced the release of all analytes except TNF-α, whose release was increased. Together, these results demonstrate a dose-dependent ability of Manuka honey to modify the release of cytokines, chemokines, and matrix-degrading enzymes that promote or inhibit inflammation and/or healing within a wound. The findings of this study provide further guidance for the future use of Manuka honey in wounds or tissue engineering templates. Future in vivo investigation is warranted to validate the in vitro results and translate these results to physiologically relevant environments.

Survival Before and After Direct Surgical Quality Feedback in a Population-Based Lung Cancer Cohort.

BACKGROUND: Surgical resection is the main curative modality for non-small cell lung cancer (NSCLC), but variation in the quality of care contributes to suboptimal survival rates. Improving surgical outcomes by eliminating quality deficits is a key strategy for improving population-level lung cancer survival. We evaluated the long-term survival effect of providing direct feedback on institutional performance in a population-based cohort. METHODS: The Mid-South Quality of Surgical Resection cohort includes all NSCLC resections at 11 hospitals in four contiguous Dartmouth Hospital Referral Regions in Arkansas, Mississippi, and Tennessee. We evaluated resections from 2004 to 2013, before and after onset of a benchmarked performance feedback campaign to surgery and pathology teams in 2009. RESULTS: We evaluated 2,206 patients: 56% preintervention (pre-era) and 44% postintervention (post-era). Preoperative positron emission tomography/computed tomography (46% vs 82%, p < 0.0001), brain scans (6% vs 21%, p < 0.0001), and bronchoscopy (8% vs 27%, p < 0.0001) were more frequently used in the post-era. Patients had 5-year survival of 47% (44% to 50%) in the pre-era compared with 53% (50% to 56%) in the post-era (p = 0.0028). The post-era had an adjusted hazard ratio of 0.85 (95% confidence interval [CI], 0.75 to 0.97; p = 0.0158) compared with the pre-era. This differed by extent of resection (p = 0.0113): compared with the pre-era, the post-era adjusted hazard ratio was 0.49 (95% CI, 0.33 to 0.72) in pneumonectomy, 0.91 (95% CI, 0.79 to 1.05) in lobectomy/bilobectomy, and 0.85 (95% CI, 0.63 to 1.15) in segmentectomy/wedge resections. CONCLUSIONS: Overall survival after surgical resection improved significantly in a high lung cancer mortality region of the United States. Reasons may include better selection of patients for pneumonectomy and more thorough staging.

Pragmatic trial of a multidisciplinary lung cancer care model in a community healthcare setting: study design, implementation evaluation, and baseline clinical results.

BACKGROUND: Responsible for 25% of all US cancer deaths, lung cancer presents complex care-delivery challenges. Adoption of the highly recommended multidisciplinary care model suffers from a dearth of good quality evidence. Leading up to a prospective comparative-effectiveness study of multidisciplinary vs. serial care, we studied the implementation of a rigorously benchmarked multidisciplinary lung cancer clinic. METHODS: We used a mixed-methods approach to conduct a patient-centered, combined implementation and effectiveness study of a multidisciplinary model of lung cancer care. We established a co-located multidisciplinary clinic to study the implementation of this care-delivery model. We identified and engaged key stakeholders from the onset, used their input to develop the program structure, processes, performance benchmarks, and study endpoints (outcome-related process measures, patient- and caregiver-reported outcomes, survival). In this report, we describe the study design, process of implementation, comparative populations, and how they contrast with patients within the local and regional healthcare system. Trial Registration: ClinicalTrials.gov Identifier: NCT02123797. RESULTS: Implementation: the multidisciplinary clinic obtained an overall treatment concordance rate of 90% (target >85%). Satisfaction scores were high, with >95% of patients and caregivers rating themselves as being "very satisfied" with all aspects of care from the multidisciplinary team (patient/caregiver response rate >90%). The Reach of the multidisciplinary clinic included a higher proportion of minority patients, more women, and younger patients than the regional population. Comparative effectiveness: The comparative effectiveness trial conducted in the last phase of the study met the planned enrollment per statistical design, with 178 patients in the multidisciplinary arm and 348 in the serial care arm. The multidisciplinary cohort had older age and a higher percentage of racial minorities, with a higher proportion of stage IV patients in the serial care arm. CONCLUSIONS: This study demonstrates a comprehensive implementation of a multidisciplinary model of lung cancer care, which will advance the science behind implementing this much-advocated clinical care model.
