Weaving the Strands of Life (Iiná Bitł’ool): History of Genetic Research Involving Navajo People
To date, some genetic studies offer medical benefits, but lack a clear pathway to benefit for people from underrepresented backgrounds. Historically Indigenous people, including the Diné (Navajo people), have raised concerns about the lack of benefits, misuse of DNA samples, lack of consultation, and ignoring cultural and traditional ways of knowing. Shortly after the Navajo Nation Human Research Review Board was established in 1996, the Navajo Nation recognized growing concerns about genetic research and established a moratorium on human genetic research studies in 2002. The moratorium effectively has protected their citizens from potential genetic research harms. Despite the placement of the moratorium, some genetic research studies have continued using blood and DNA samples from Navajo people. In order to understand the history of genetic research involving Navajo people, we conducted a literature review of 79 genetic or genetic-related research publications that involved Navajo people from the years 1925 to 2018. In this review, we divided the genetic research studies into the following general classifications: a) bacteria or virus genetics studies, b) blood and human leukocyte antigen, c) complex diseases, d) forensics, e) hereditary diseases, and f) population genetics and migration. We evaluated the methods for each study, described the number of Navajo individuals included in each study, recorded the academic or tribal approval statements, and noted whether the study considered Diné cultural values. Several studies focused on Severe Combined Immunodeficiency Disease, population history, neuropathy, albinism, eye and skin disorders that affect Navajo people. We found genetic research publications involving Navajo people spanning over the course of 93 years. To our knowledge, no known literature reviews have examined the history of genetic research in the Navajo community. In our Discussion, we contextualize Diné ways of knowing related to genetics and health with Western scientific concepts to acknowledge the complex philosophy and belief system that guides Diné people and recognizes Indigenous science. We encourage researchers consider cultural perspectives and traditional knowledge that has the potential to create stronger conclusions and better informed, ethical, and respectful science

Association of plasma cytokines and antidepressant response following mild-intensity whole-body hyperthermia in major depressive disorder
Abstract Whole-body hyperthermia (WBH) shows promise for the treatment of major depressive disorder (MDD). Because MDD is associated with increased inflammation, and anti-inflammatory agents show some promise as antidepressants, the current study sought to identify the acute and longer-term immune effects of WBH in participants with MDD and to explore whether these effects associate with the procedure’s antidepressant properties. Thirty participants who met DSM-IV-TR criteria for MDD were randomized to receive a single session of WBH (n = 16) or sham treatment (n = 14). Hamilton Depression Rating Scale (HDRS) scores were assessed at baseline and 1, 2, 4, and 6 weeks post-treatment (WBH vs. sham), and plasma cytokine concentrations were assessed at baseline, immediately post-treatment, and 1 and 4 weeks post-treatment. As previously reported, WBH produced a rapid and sustained antidepressant effect. When compared to sham, WBH increased plasma interleukin (IL)-6 immediately post-treatment (time by treatment: χ 2 (3, N=108) = 47.33, p < 0.001), while having no effect on other cytokines acutely and no impact on IL-6, or any other cytokine, at 1 or 4 weeks post treatment. In the study sample as a whole, increased IL-6 post-treatment was associated with reduced HDRS depression scores over the 6 weeks of follow-up (F (1, 102.3) = 6.74, p = 0.01). These results suggest a hitherto unrecognized relationship between hyperthermia, the immune system, and depression, and may point to WBH as a novel modality for exploring behavioral effects of IL-6 when the cytokine is activated in isolation from the inflammatory mediators with which it frequently travels

Water Back: A Review Centering Rematriation and Indigenous Water Research Sovereignty
The recent Land Back movement has catalysed global solidarity towards addressing the oppression and dispossession of Indigenous Peoples’ Lands and territories. Largely absent from the discourse, however, is a discussion of the alienation of Indigenous Peoples from Water by settler-colonial states. Some Indigenous Water Protectors argue that there cannot be Land Back without Water Back. In response to this emergent movement of Water Back, this review of research by Indigenous and non-Indigenous writers traces the discursive patterns of Indigenous Water relationships and rematriation across themes of colonialism, climate change, justice, health, rights, responsibilities, governance and cosmology. It advances a holistic conceptualization of Water Back as a framework for future research sovereignty, focusing mainly on instances in Canada, Australia, Aotearoa New Zealand, and the United States. We present the findings on the current global Waterscape of Indigenous-led research on Indigenous Water issues. Water Back offers an important framework centring Indigenous ways of knowing, doing, and being as a foundation for advancing Indigenous Water research. © THIS ARTICLE IS DISTRIBUTED UNDER THE TERMS OF THE CREATIVE COMMONS ATTRIBUTION-NONCOMMERCIAL-SHAREALIKE LICENSE WHICH PERMITS ANY NON COMMERCIAL USE, DISTRIBUTION, AND REPRODUCTION IN ANY MEDIUM, PROVIDED THE ORIGINAL AUTHOR(S) AND SOURCE ARE CREDITED.
