Walking in beauty: Responsive and responsible health and healing among Virginia American Indian people

Little is systematically known about the collective health and well-being of Virginia American Indian people. This study sought to explore the meaning of health and healing among Virginia American Indian people in the context of a reservation-based, non-federally funded health clinic. Using an emergent approach to qualitative research grounded in a constructivist inquiry paradigm and guided by Indigenous research principles, a total of 24 in-depth, semi-structured interviews were conducted with 17 American Indian service-users of the Clinic. Through an inductive thematic analysis of participant stories, a framework for understanding responsive and responsible health and healing was derived. The framework includes seven dimensions: spirituality, physical processes, mental and emotional processes, social relationships, access to resources, contextual factors, and the interconnection among the dimensions. Personal and collective identity was a significant element woven through the dimensions. From the stories told by participants, health seems to be a continuum and healing seems to be a cycle. With constant motion in each of the dimensions, health has to do with sustained engagement in healing processes that continually seek to bring about functional balance in one’s whole health system. Ill health has to do with when a change in any one of the dimensions overtakes one’s ability to bring about a functional balance in the whole health system. The framework is context-dependent, true for the people who participated in the study at the time of the study

A Culturally-Relevant, Emergent Approach to Exploring the Needs, Strengths, and Priorities of Tribal Communities in Virginia

Little is known about the health of the indigenous peoples in Virginia. When compared to the total U.S. population, indigenous peoples nationwide disproportionately experience disparities in health status across multiple health indicators. Research shows that these disparities are largely due to the inequitable distribution of social and economic determinants present within indigenous communities. Because the indigenous peoples of Virginia are affected by inequitable social and economic conditions, there is reason to believe that health indicators may mirror that of the indigenous population at-large. Outlined in this paper is a framework for exploring the needs, strengths, and priorities of indigenous communities in Virginia. This paper proposes that the use of a culturally relevant methodology, such as Talking Circle, combined with an emergent and community-based participatory approach, will lead to a more authentic identification of the strengths, needs, and priorities of indigenous communities than traditional public health surveillance methodology, as well as build community capacity for on-going engagement

Crucial role of SLP-76 and ADAP for neutrophil recruitment in mouse kidney ischemia-reperfusion injury

Neutrophils trigger inflammation-induced acute kidney injury (AKI), a frequent and potentially lethal occurrence in humans. Molecular mechanisms underlying neutrophil recruitment to sites of inflammation have proved elusive. In this study, we demonstrate that SLP-76 (SH2 domain–containing leukocyte phosphoprotein of 76 kD) and ADAP (adhesion and degranulation promoting adaptor protein) are involved in E-selectin–mediated integrin activation and slow leukocyte rolling, which promotes ischemia-reperfusion–induced AKI in mice. By using genetically engineered mice and transduced Slp76(−/−) primary leukocytes, we demonstrate that ADAP as well as two N-terminal–located tyrosines and the SH2 domain of SLP-76 are required for downstream signaling and slow leukocyte rolling. The Tec family kinase Bruton tyrosine kinase is downstream of SLP-76 and, together with ADAP, regulates PI3Kγ (phosphoinositide 3-kinase–γ)- and PLCγ2 (phospholipase Cγ2)-dependent pathways. Blocking both pathways completely abolishes integrin affinity and avidity regulation. Thus, SLP-76 and ADAP are involved in E-selectin–mediated integrin activation and neutrophil recruitment to inflamed kidneys, which may underlie the development of life-threatening ischemia-reperfusion–induced AKI in humans

Modeling seasonal emergence of Poa annua in urban greenspace

AbstractTurfgrasses are perennial components of urban greenspaces found in parks, recreational areas, golf courses, sports fields, and lawns that confer many ecosystem services. A copious seed producer, Poa annua is the most troublesome weed of turfgrass and continually threatens the ecosystem services provided by urban greenspaces. Field research was conducted in Knoxville, TN to better understand environmental conditions triggering P. annua seedling emergence patterns to assist managers with optimally timing interventions—both chemical and non-chemical—for control. Fluctuations in cooling degree day (CDD21C) accumulation accounted for 82% of the variance in yearly cumulative P. annua emergence data collected in a single irrigated sward of hybrid bermudagrass [C. dactylon (L.) Pers. x. C. transvaalensis Burtt-Davy]. However, non-linear models using CDD21C data developed ex post were not able to accurately predict P. annua emergence patterns ex ante. In both years, P. annua emergence changed most rapidly between the 40th and 43rd week of the year when seven-day mean soil temperature and rainfall were 18.9 °C and 12.7 mm, respectively. Future research should explore the efficacy of herbicide mixtures applied when P. annua emergence is most rapidly changing in lieu of developing models to predict when specific emergence thresholds occur.</jats:p
