"I Had Nobody to Represent Me": How Perceptions of Diabetes Health-Care Providers' Age, Gender and Ethnicity Impact Shared Decision-Making in Adults With Type 1 and Type 2 Diabetes.

OBJECTIVES: Our aim in this study was to investigate how patients' perceptions of their diabetes health-care providers' (HCP) age, gender and ethnicity impact shared decision-making using the Theory of Planned Behaviour. METHODS: Adult participants receiving diabetes care at community sites, primary care or specialty clinics participated in semistructured, one-on-one interviews conducted from November 2018 to January 2019. Responses were transcribed and qualitatively analyzed for emergent themes using statistical software (NVivo version 9). RESULTS: We conducted 28 interviews with participants 34 to 81 years of age. The following themes were identified: 1) participants' gestalt of their diabetes HCP was strongly gender dependent 2) there was a hidden preference for Caucasian HCPs, 3) age evoked a less defensive response with regard to shared decision-making and 4) degree of trust in self and in their diabetes HCP directed participants' readiness to be part of the shared decision-making. CONCLUSIONS: Participants' narrative experiences strongly suggest that they view their diabetes HCPs through a gendered and racialized lens.

Development and Implementation of Peer Leader Training for Community-Based Participatory Sexual Health Research.

BACKGROUND: Building the collective capacity of racialized women to meaningfully lead and engage in research is critical to health equity. To address the silence and stigma related to HIV/sexually transmitted infections (STIs) among South Asian women in Canada, peer leadership and engagement were identified as important strategies to promote open discussion about sexual health. OBJECTIVES: Underpinned by the principle of 'nothing about us without us', the objectives of the Story Sharing for Sexual Health (SSSH) research study included engaging and training South Asian women peer leaders to become an integral part of the study and build community research capacity. To achieve these objectives, it was critical to support the peer leaders in gaining a thorough understanding of the research ethics, protocols and teamwork principles, and to consolidate skills in group facilitation and community engagement. METHODS: The peer leaders attended four full-day training sessions on the social determinants of health and gender equity for racialized populations, HIV/STI and sexual health in the context of South Asian communities, community-based participatory research (CBPR) principles, skills in focus group facilitation, community partnerships building, and storytelling epistemologies. A training manual was developed. Evaluation of the training program included 1) evaluation forms, 2) process evaluations through journal writing and feedback sessions, and 3) implementation outcomes. CONCLUSIONS: The SSSH peer research training program was effective. Peer leaders demonstrated effectiveness in liaising with partner agencies, engaging South Asian women in sexual health discussion, completing CBPR activities and team building. Knowledge generated can be applied in CBPR with other racialized women populations.

Exploring the use of fact-based and story-based learning materials for HIV/STI prevention and sexual health promotion with South Asian women in Toronto, Canada.

Story-based learning is well recognized as an effective strategy for adult health education. However, there is a scarcity of research on story-based health education among women in South Asian diasporic communities. To address this gap, we undertook a pilot study in Toronto to explore how South Asian women respond to the use of fact-based and story-based materials for HIV/STI prevention. A total of 78 women were recruited from across the city. We engaged nearly half of the women (n=40) using fact sheets on HIV/STIs, and the remainder (n=38) using stories written by South Asian women on HIV/STIs. Surveys and focus groups were used to explore participants' responses in terms of knowledge, attitudes and perspectives. Results indicated that both approaches were effective in increasing participants' knowledge of HIV/STIs. Participants in the fact-based sessions tended to distance themselves from the idea of personal HIV/STI risks. Participants in the story-based groups were emotionally engaged, expressing personal commitments to take a stand against HIV stigma. In summary, within-culture stories are potentially effective tools that enable women to make sense of their own life situations and contextual vulnerabilities. Story-based materials are useful for breaking the silence of taboo topics, addressing stigma and discrimination and raising awareness about collective empowerment.

Evaluation of nicotinamide as an anti-inflammatory and anti-angiogenic agent in uveal melanoma cell lines.

PURPOSE:: To investigate the effect of nicotinamide on the secretion of pro-an giogenic and pro-inflammatory cytokines in uveal melanoma cell lines. METHODS:: Two human uveal melanoma cell lines (92.1 and OCM-1) were treated with nicotinamide (10 mmol/L) or control media for 48 hours in culture. The su perna tant from each culture was used in sandwich enzyme-linked immuno sorbent assay-based angiogenesis and inflammation arrays to evaluate the effects of exogenously administered nicotinamide on the secretion of a total of 20 pro-an gio genic and pro-inflammatory proteins. RESULTS:: Seven pro-angiogenic cytokines were detected under control conditions for both uveal melanoma cell lines. Treatment with nicotinamide resulted in a significant decrease in secretion of the following pro-angiogenic cytokines: angiogenin, angiopoietin-2, epidermal growth factor, and vascular epithelial growth factor-A in the 92.1 cells; basic fibroblast growth factor in the OCM-1 cells; and placenta growth factor in both cell lines. Among the pro-inflammatory proteins, monocyte chemotactic protein-1 and interleukin-8 were expressed in both untreated cell lines and both were significantly reduced when treated with nicotinamide. CONCLUSIONS:: Results from this in vitro model suggest that nicotinamide may have anti-inflammatory and anti-angiogenic properties, which may open the possibility of using it as a chemopreventive agent for uveal melanoma; however, further studies including animal models are warranted.

RESUMO Objetivo: Acredita-se que a nicotinamida (NIC) seja capaz de diminuir a angiogênese induzida pelo fator de crescimento endotelial vascular (VEGF). Investigar os efeitos da nicotinamida sobre a secreção de citocinas pró-angiogênicas e pró-inflamatórias em linhagens de células de melanoma uveal humano (UM). Métodos: Duas linhagens de células humanas de UM (92,1 e OCM-1) foram tratadas com NIC (10 mmol/L) ou apenas com meio de cultura por 48 horas. O sobrenadante das culturas obtido após a administração de nicotinamida foi comparado com o sobrenadante das culturas controle quanto à expressão de 20 fatores pró-angiogênicos e pró-inflamatórios, pela técnica de enzyme-linked immunosorbent assay (ELISA). Resultados: Sete citocinas pró-angiogênicas foram detectadas nas condições de controle em ambas as linhagens de células de UM. O tratamento com nicotinamida promoveu uma redução significativa da secreção das seguintes citocinas angiogênicas: Angiogenina, ANG2, EGF e VEGF-A em células 92.1; bFGF em células OCM-1; PIGF em ambas as linhagens celulares. Quanto às proteínas pró-inflamatórias, a expressão de MCP-1 e IL-8 foi significativamente reduzida com a administração de nicotinamida em relação às culturas de células que não receberam o tratamento. Conclusões: Nicotinamida apresenta propriedades anti-inflamatórias e anti-angiogênicas em modelo experimental in vitro. Tais efeitos sugerem a possibilidade de utilizar esta substância na quimioprevenção do UM. Entretanto, estudos com modelos experimentais in vivo são necessários para melhor avaliar o benefício do tratamento do UM com nicotinamida.
