OBJECTIVES/OBJECTIVE:To identify stakeholder perceived challenges and facilitators for implementing a clean fuel and clean stove intervention to reduce household air pollution and hypertension in Lagos, Nigeria. DESIGN/METHODS:Qualitative study guided by the Exploration and Preparation phases of the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework, using focus group discussions and in-depth semi-structured interviews with inductive and deductive thematic analysis. SETTING/METHODS:Peri-urban communities across the five administrative divisions of Lagos State, Nigeria. PARTICIPANTS/METHODS:128 stakeholders from 32 communities, including community, religious, market and youth leaders, primary healthcare staff, and household decision makers. Approximately half were female. INTERVENTIONS/METHODS:This was a pre-implementation needs assessment that included demonstrations of the clean stove and fuel. PRIMARY AND SECONDARY OUTCOME MEASURES/METHODS:Thematic domains describing barriers and enablers to adoption and implementation, mapped to EPIS inner, outer, and bridging factors. RESULTS:Stakeholders reported barriers that included stove stacking, upfront stove cost, concerns about long-term fuel price and availability, equipment durability and maintenance, safety, mistrust of new technology, and uncertainty about stove performance for dishes requiring high heat and long cooking times. Reported facilitators included payment flexibility and subsidies, opportunities to test the stove, perceived benefits of cleaner and faster cooking with less soot, endorsement by community leaders, and interest in local retail and distribution to improve access. CONCLUSIONS:Implementation planning for clean fuel and clean stove programmes should address affordability, reliable fuel supply chains, durability and service, culturally relevant cooking needs, and trust building through community leadership. These findings inform adaptation strategies for scale-up in similar low-resource settings. TRIAL REGISTRATION NUMBER/BACKGROUND:NCT05048147.

INTRODUCTION/BACKGROUND:In Africa, 75% of households are exposed to household air pollution (HAP), a key contributor to cardiovascular disease (CVD). In Nigeria, 90 million households rely on solid fuels for cooking, and 40% of adults have hypertension. Though clean fuel and clean stove (CF-CS) technologies can reduce HAP and CVD risk, their adoption in Africa remains limited. METHODS AND ANALYSIS/METHODS:Using the Exploration, Preparation, Implementation and Sustainment framework, this cluster-randomised controlled trial evaluates the implementation and effectiveness of a community mobilisation (CM) strategy versus a self-directed condition (i.e., receipt of information on CF-CS use without CM) on adoption of CF-CS technologies and systolic blood pressure (SBP) reduction among 1248 adults from 624 households across 32 peri-urban communities in Lagos, Nigeria. The primary outcome is CF-CS adoption at 12 months; secondary outcomes are SBP reduction at 12 months and sustainability of CF-CS use at 24 months. Adoption is assessed via objective monitoring of stove usage with temperature-triggered iButton sensors. SBP is assessed in 2 adults per household using validated automated blood pressure monitor. Generalised linear mixed-effects regression models will be used to assess study outcomes, accounting for clustering at the level of the peri-urban communities (unit of randomisation) and households. To date, randomisation is completed, and a total of 1248 households have enrolled in the study. The final completion of the study is expected in June 2026. ETHICS AND DISSEMINATION/BACKGROUND:The study was approved by the Institutional Review Boards (IRB) of NYU Grossman School of Medicine (primary IRB of record; protocol ID: i21-00586; Version 6.0 approved on 4 June 2024), and Lagos State University Teaching Hospital (protocol ID: LREC 06/10/1621). Written consent was obtained from all participants. Findings will inform scalable and culturally appropriate strategies for reducing HAP and CVD risk in low-resource settings. Results will be disseminated through peer-reviewed publications, conference presentations and stakeholder engagements. TRIAL REGISTRATION NUMBER/BACKGROUND:NCT05048147.

OBJECTIVES/OBJECTIVE:In mild traumatic brain injury, imaging biomarkers are needed to support clinical management. In four antecedent publications, we used two new (sodium and fingerprinting) and two established (spectroscopy and diffusion) MR techniques in a longitudinally followed patient cohort. Here we report final results and combine all data to determine which marker(s) from the four modalities offer the greatest utility for detecting injury and predicting outcomes. We also leverage the independent specificities offered by each modality to explore injury mechanisms. MATERIALS AND METHODS/METHODS:The longitudinal spectroscopy data were analysed to complete a full data set of proton (spectroscopy, fingerprinting, diffusion) and sodium MRI, acquired alongside symptomatic, cognitive, and functional assessments in 27 patients at 1, 3, and 12 months following injury. Twenty-three matched controls were scanned once. Testing for associations between nine MR markers and three outcome measures was standardized across the entire data set, and performed using Spearman correlations and logistic regression. RESULTS:from fingerprinting (marker of the cellular microenvironment). CONCLUSIONS:We identified independent, dynamic, metabolic and ionic changes, with choline and creatine from spectroscopy fulfilling the most criteria for a clinical biomarker.

Research shows that donor families report feeling abandoned, lacking social support, and receiving insufficient aftercare services. To meet the needs of these families, Taylor's Gift Foundation developed a free, virtual grief support program that pairs participating donor family members with Caring Guides trained in assertive community engagement and offers peer-facilitated support groups. Project Aim: The aim was to assess participant experiences with Taylor's Gift Foundation grief support program to understand its impact on grief symptoms, donor family access to grief support, and perceived social support. Design: Researchers conducted a qualitative evaluation using semi-structured interviews with 21 program participants. Results were analyzed using rapid qualitative analysis and descriptive statistics. Results: Eighteen (86%) participants worked with Caring Guides, 12 (57%) attended an average of 7 support groups, and 8 (39%) worked with Caring Guides and attended support groups. Eleven (52%) program participants reported difficulties accessing mental health services. Most program participants (86%) reported a decrease in grief intensity since enrolling in the program. Conclusion: Effective aftercare services were critical in helping donor families cope with, and adapt to, their loss. The Taylor's Gift Foundation grief support program helped donor family members access otherwise inaccessible grief support services and provided a valuable means of social support.
