RESUMO

Introduction: We carried out a two-phase, qualitative evaluation of a novel public health campaign to promote COVID-19 vaccination among youth and young adults of color (YOC), called Survival Pending Revolution. The campaign, commissioned by California's Department of Public Health, was created by YOC spoken word artists, under the direction of the organization, Youth Speaks. Methods: In phase 1, we describe the communication attributes of the campaign's nine video-poems, coded the content of the pieces, and applied thematic analysis to describe the themes conveyed. In phase 2, we carried out a comparative health communication study to assess the content's potential value. We exposed a sample of the target audience (YOC) to the content of Survival Pending Revolution and a widely viewed comparator campaign (The Conversation). Using a focus group, we solicited participants' views using a semi-structured approach. Using thematic analysis, we summarized the reactions that arose when participants reflected on the attributes of each campaign. Results: Findings from phase 1 reveal how engaging YOC artists who embrace Youth Speaks' philosophy of harnessing "life as primary text" resulted in content that is aligned with critical communication theory, focusing on structural determinants of health, including themes of overcoming oppressive systems, health and social inequities, and medical discrimination and mistrust. Findings from phase 2 reveal that this arts-based campaign based on such critical communication theory, when compared to a more traditional campaign, promotes message salience, fosters emotional engagement, and provides a form of validation among historically oppressed groups such that they may be more open to, and potentially act on, the COVID-19 vaccination communications to which they are exposed. Discussion: As an example of critical communication, the Survival Pending Revolution campaign encourages health-promoting behavioral decisions while calling out the structural determinants of health that shape risks of exposure and constrain free choice. Engaging uniquely gifted members of marginalized populations as creators and messengers of campaigns lead to content that is aligned with a critical communication approach, whose goal is to aid disparity populations in both resisting and navigating systems that continue to locate them on the margins of society. Our evaluation of this campaign suggests that it represents a promising formative and interventional approach to engendering trust in public health messaging and promoting health equity.

RESUMO

The objective was to analyze and systematize evidence reported in qualitative studies on the reasons and consequences of tooth loss in adults and elderly people in Brazil. A systematic review of the literature on qualitative research methods and a meta synthesis of the results were performed. The study population consisted of adults over 18 years of age and elderly people in Brazil. Searches were performed in the BVS, PubMed, Scopus, Web of Science, BBO, Embase, EBSCO and SciELO databases. The thematic synthesis identified 8 analytical themes regarding reasons for tooth loss and 3 analytical themes regarding consequences of tooth loss. Dental pain, care model, financial situation and desire for prosthetic rehabilitation were determining factors for extractions. There was recognition of negligence in oral care, and the naturalness of tooth loss was linked to old age. Missing teeth caused psychological and physiological impacts. It is imperative to verify whether the factors that cause tooth loss persist, and how much those factors influence decisions to extract teeth among current young and adult populations. It is necessary to change the care model through the inclusion and qualification of oral health care for the young and elderly adult populations; otherwise, the model of dental mutilation and the culture of edentulism will persist.

RESUMO

The COVID-19 pandemic, coupled with the domestic socio-political unrest of 2020, provides a critical opportunity to reframe how we engage with youth around health and disease risk. The Bigger Picture (TBP), a spoken word, arts-based public health literacy campaign, uses a social justice and racial equity frame to activate youth around social determinants of health, including salient topics such as type 2 diabetes, COVID-19, climate change, and police violence. This quasi-experimental study determined the impact of providing an online adaptation of TBP during the COVID-19 pandemic to urban, low-income, diverse high school students (3 intervention schools assigned to receive TBP-based spoken word program; 3 comparison schools received a non-health focused spoken word program). We used outcomes derived from the Culture of Health framework, including: (1) health-related mind-sets and expectations; (2) sense of belonging; and (3) civic engagement. Students completed pre/post surveys; a subset of adults and youth from all 6 schools completed semi-structured interviews. TBP participation resulted in measurable shifts in students' mind-sets around structural drivers of health and health inequity and increases in plans for future civic engagement. Arts-based programming with an intentional focus on the social ecological model and health equity appears to impact young people, even when delivered online.

RESUMO

Traditional health education efforts rarely align with youth social justice values. The Bigger Picture (TBP), a spoken word arts campaign, leverages a social justice approach to activate youth around the social determinants of type 2 diabetes (T2D). This quasi-experimental study examines the impact of embedding TBP in urban, low-income high schools (3 intervention schools received TBP; 3 comparison schools received a non-health related spoken word program) with respect to (1) health-related mind-sets and expectations; (2) sense of belonging; and (3) civic engagement among youth. Adults and youth who participated in programming at all 6 schools were interviewed, and a content analysis of students' poems was performed. TBP was well-received by adults and students. While students in both TBP and comparison programs described multiple social determinants of T2D, intervention students more frequently articulated the connections between race/ethnicity and T2D as a social justice issue. Further, all comparison students explicitly mentioned individual dietary behavior as a T2D determinant while most, yet not all, intervention students did. Students in both programs reported a high sense of belonging at school and confidence in civic engagement. Content analysis of TBP students' poems revealed youth's detailed understanding of T2D determinants. Future studies might explore program scalability, and how the integration of civic engagement opportunities into TBP curriculum might impact students' capacity to create positive social change.

RESUMO

Phenylalanine ammonia-lyase (PAL) is the first enzyme of the general phenylpropanoid pathway catalyzing the nonoxidative elimination of ammonia from l-phenylalanine to give trans-cinnamate. In monocots, PAL also displays tyrosine ammonia lyase (TAL) activity, leading to the formation of p-coumaric acid. The catalytic mechanism and substrate specificity of a major PAL from sorghum (Sorghum bicolor; SbPAL1), a strategic plant for bioenergy production, were deduced from crystal structures, molecular docking, site-directed mutagenesis, and kinetic and thermodynamic analyses. This first crystal structure of a monocotyledonous PAL displayed a unique conformation in its flexible inner loop of the 4-methylidene-imidazole-5-one (MIO) domain compared with that of dicotyledonous plants. The side chain of histidine-123 in the MIO domain dictated the distance between the catalytic MIO prosthetic group created from 189Ala-Ser-Gly191 residues and the bound l-phenylalanine and l-tyrosine, conferring the deamination reaction through either the Friedel-Crafts or E2 reaction mechanism. Several recombinant mutant SbPAL1 enzymes were generated via structure-guided mutagenesis, one of which, H123F-SbPAL1, has 6.2 times greater PAL activity without significant TAL activity. Additional PAL isozymes of sorghum were characterized and categorized into three groups. Taken together, this approach identified critical residues and explained substrate preferences among PAL isozymes in sorghum and other monocots, which can serve as the basis for the engineering of plants with enhanced biomass conversion properties, disease resistance, or nutritional quality.
