Selective Oxidation of Glycerol via Acceptorless Dehydrogenation Driven by Ir(I)-NHC Catalysts.

Iridium(I) compounds featuring bridge-functionalized bis-NHC ligands (NHC = N-heterocyclic carbene), [Ir(cod)(bis-NHC)] and [Ir(CO)2(bis-NHC)], have been prepared from the appropriate carboxylate- or hydroxy-functionalized bis-imidazolium salts. The related complexes [Ir(cod)(NHC)2]+ and [IrCl(cod)(NHC)(cod)] have been synthesized from a 3-hydroxypropyl functionalized imidazolium salt. These complexes have been shown to be robust catalysts in the oxidative dehydrogenation of glycerol to lactate (LA) with dihydrogen release. High activity and selectivity to LA were achieved in an open system under low catalyst loadings using KOH as a base. The hydroxy-functionalized bis-NHC catalysts are much more active than both the carboxylate-functionalized ones and the unbridged bis-NHC iridium(I) catalyst with hydroxyalkyl-functionalized NHC ligands. In general, carbonyl complexes are more active than the related 1,5-cyclooctadiene ones. The catalyst [Ir(CO)2{(MeImCH2)2CHOH}]Br exhibits the highest productivity affording TONs to LA up to 15,000 at very low catalyst loadings.

Resident-Led Neighborhood Development to Support Health: Identifying Strategies Using CBPR.

Evidence suggests that where people live, learn, work, and play affects a range of health outcomes for children and adults. Differential access to social, economic, and environmental supports puts some community members at greater risk, leading to disparities in health and well-being. The 2014 release of the For the Sake of All report highlighted persistent health disparities for African Americans in St. Louis, Missouri, and their social and economic impacts on the St. Louis region. This study extends this work by developing partnerships with community organizations and neighborhood residents to address health disparities. Community-based participatory research (CBPR) methods were utilized to engage partners in a 10-month research process to address community concerns that impact health. Seven community residents, neighborhood researchers, engaged in workshops to learn about the research process and used techniques to gather information to implement action strategies. Neighborhood researchers selected 14 vacant lots to implement their action plan, which included visions for repurposing the land into a community park, produced a report for dissemination, and organized a community action forum to communicate their findings. This study highlights a promising approach to promote healthy communities and health equity by empowering neighborhood residents using participatory methodologies.

Priorities for Patient-Centered Outcomes Research: The Views of Minority and Underserved Communities.

OBJECTIVE: To learn how minority and underserved communities would set priorities for patient-centered outcomes research (PCOR). DATA SOURCES: Sixteen groups (n = 183) from minority and underserved communities in two states deliberated about PCOR priorities using the simulation exercise CHoosing All Together (CHAT). Most participants were minority, one-third reported income <$10,000, and one-fourth reported fair/poor health. DESIGN: Academic-community partnerships adapted CHAT for PCOR priority setting using existing research agendas and interviews with community leaders, clinicians, and key informants. DATA COLLECTION: Tablet-based CHAT collected demographic information, individual priorities before and after group deliberation, and groups' priorities. PRINCIPAL FINDINGS: Individuals and groups prioritized research on Quality of Life, Patient-Doctor, Access, Special Needs, and (by total resources spent) Compare Approaches. Those with less than a high school education were less likely to prioritize New Approaches, Patient-Doctor, Quality of Life, and Families/Caregivers. Blacks were less likely to prioritize research on Causes of Disease, New Approaches, and Compare Approaches than whites. Compare Approaches, Special Needs, Access, and Families/Caregivers were significantly more likely to be selected by individuals after compared to before deliberation. CONCLUSIONS: Members of underserved communities, in informed deliberations, prioritized research on Quality of Life, Patient-Doctor, Special Needs, Access, and Compare Approaches.
