Mechanism of olfactory deficit in neurotrauma and its related affective distress: A narrative review

Traumatic brain injury (TBI) is among the leading causes of death and disability all over the globe. TBI is also commonly associated with clinical sequelae of posttraumatic depression, and reports of other subsequent affective distress are common. Similarly, posttraumatic changes in chemoreceptive sensory functions, primarily due to coup-contrecoup injury induced shearing of the olfactory nerve fibers, leading to anosmia and ageusia are also well documented in the literature. However, the current literature is limited in addressing the intersections between said variables. The aim of this study was to provide a focused narrative review of the literature, to address these intersections found in clinical sequelae of TBI. As chemoreceptive sensory deficits are also linked to significant affective distress of their own, this review addresses the bidirectionality between sensory deficit and affective distress. Prevalence, demographics, mechanisms, and clinical implications are presented. Previous research is presented and discussed, in an effort to highlight the importance of consideration for all factors in TBI patient care and future research.     

Space within the Scientific Discourse for the Voice of the Other? Expressions of Community Voice in the Scientific Discourse of Community-Based Participatory Research

ABSTRACT

Community-based participatory research (CBPR) has captured public health attention and support because it is positioned as an approach that involves researchers and communities as equitable partners in addressing health disparities. However, it is unknown the extent to which CBPR creates a participatory space in the scientific discourse to signal “community voice,” which we define as textual expression of community-centered perspectives on collective roles, interests, and worldviews. In this study, we utilized the culture-centered approach to examine the expression of community voice in the abstracts and public health relevance statements of 253 extramural CBPR projects in the U.S. that received funding from the National Institute of Health and Centers for Disease Control and Prevention in 2009. We found that project abstracts and public health relevance statements contain four textual domains, or potential sites of contest to signal the articulation of community agency and voice within the CBPR projects. These domains include: 1) the rationale for the community health issue, 2) the roles of community partners, 3) community-centered outcomes of the partnership, and 4) elements of participatory research process. The degree of culture-centeredness of the texts is suggested in the extent to which articulations of community agency and voice are signaled across the four domains. We conclude that the dynamics of CBPR may shape culture-centered expressions of problem identification, solution configuration, structural transformations, reflexivity, values, and agency in the project abstracts and public health relevance statements.
