Indigenous Research Ethics Requirements: An Examination of Six Tribal Institutional Review Board Applications and Processes in the United States.

Tribal Institutional Review Boards (TIRBs) in the United States assert their rights within sovereign nations by developing ethical research processes that align with tribal values to protect indigenous knowledge systems and their community from cultural appropriation, exploitation, misuse, and harm. We reviewed six TIRB applications and processes to gain a better understanding about their requirements and research ethics. We located 48 activated and deactivated TIRBs in a database, mapped them in relation to tribal reservation lands, and then conducted in-depth content analysis. Our analysis demonstrates the importance of building relationships, becoming fully acquainted with the TIRB's operating environment before seeking research approval, and issues related to tribal data management practices.

Native American Perspectives on Health and Traditional Ecological Knowledge.

BACKGROUND: Traditional ecological knowledge (TEK) is a conceptual framework that highlights Indigenous knowledge (IK) systems. Although scientific literature has noted the relevance of TEK for environmental research since the 1980s, little attention has been given to how Native American (NA) scholars engage with it to shape tribal-based research on health, nor how non-Native scholars can coordinate their approaches with TEK. This coordination is of particular importance for environmental health sciences (EHS) research exploring interdisciplinary approaches and the integration of environmental and human health. OBJECTIVE: Our perspective on TEK arose from a series of Health and Culture Research Group (HCRG) workshops that identified gaps in existing EHS methodologies that are based on a reliance on Euro-American concepts for assessing environmental exposures in tribal communities. These prior methods neither take into account cultural behavior nor community responses to these. Our objective is to consider NA perspectives on TEK when analyzing relationships between health and the environment and to look at how these may be applied to address this gap. DISCUSSION: The authors­the majority of whom are NA scholars­highlight two research areas that consider health from a TEK perspective: food systems and knowledge of medicinal plants. This research has yielded data, methods, and knowledge that have helped Indigenous communities better define and reduce health risks and protect local natural food resources, and this TEK approach may prove of value to EHS research. CONCLUSION: NA perspectives on TEK resulting from the HCRG workshops provide an opportunity for developing more accurate Indigenous health indicators (IHI) reflecting the conceptualizations of health maintained in these communities. This approach has the potential to bridge the scientific study of exposure with methods addressing a tribal perspective on the sociocultural determinants of health, identifying potential new areas of inquiry in EHS that afford nuanced evaluations of exposures and outcomes in tribal communities. https://doi.org/10.1289/EHP1944.

Molecular detection of viable bacterial pathogens in water by ratiometric pre-rRNA analysis.

Ratiometric pre-rRNA analysis (RPA) detects the replenishment of rRNA precursors that occurs rapidly upon nutritional stimulation of bacterial cells. In contrast to DNA detection by PCR, RPA distinguishes viable from inactivated bacteria. It exhibits promise as a molecular viability test for pathogens in water and other environmental samples.
