The power of language: how to bridge the gap between healthcare research and patients - a scoping review.

OBJECTIVE: The value of patient involvement to the design, conduct, and outcomes of healthcare research is increasingly being recognized. Patient involvement also provides greater patient accessibility and contribution to research. However, the use of inaccessible and technical language when communicating with patients is a barrier to effective patient involvement. METHODS: We analyzed peer-reviewed and gray literature on how language is used in communication between healthcare researchers and patients. We used this analysis to generate a set of recommendations for healthcare researchers about using more inclusive and accessible language when involving patients in research. This scoping review adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for Scoping Review (PRISMA-ScR) checklist. RESULTS: Four major themes about the use of language were developed from the literature analysis and were used to develop the set of recommendations. These recommendations include guidance on using standardized terminology and plain language when involving patients in healthcare research. They also discuss the implementation of co-development practices, patient support initiatives, and researcher training, as well as ways to improve emotional awareness and the need for greater equality, diversity, and inclusion. DISCUSSION AND CONCLUSION: The use of inclusive, empathetic, and clear language can encourage patients to be involved in research and, once they are involved, make them feel like equal, empowered, and valued partners. Working toward developing processes and guidelines for the use of language that enables an equal partnership between researchers and patients is critical.

Patient and public involvement is when patients, carers, and the public are included as partners in all stages of healthcare research. Patient involvement has been shown to have a positive impact on people and on research itself, but researchers often use language that is complicated, confusing, or unsuitable for patients. This can lead to less meaningful patient involvement in research.Our work looked at two areas: (1) how using unsuitable language can be a barrier to effective and meaningful patient involvement; and (2) what can be done to help improve communication between healthcare researchers and patients.We started by finding out what has already been researched and published in these areas. We looked in medical journal databases for articles that were relevant to the topic. We also searched Google and the websites of relevant organizations. From looking at these sources, we found four common themes. These themes are: (1) lack of standardized terminology for patients involved in research; (2) consistent overuse of technical, scientific, and medical language; (3) positive outcomes of using language to show emotional understanding; and (4) language as a powerful tool for promoting diversity, equality, and inclusion of patients involved in research.Using these themes, we then developed seven recommendations to help improve how healthcare researchers and patients communicate with each other. These recommendations are: (1) using standardized terminology; (2) using plain language; (3) co-developing patient information; (4) providing patient training, mentoring, and support; (5) introducing researcher training; (6) having emotional awareness; and (7) improving equality, diversity, and inclusion.A graphical plain language summary can be found as Supplementary material for this article.

Characterising meaningful patient and public involvement in the pharmaceutical industry research setting: a retrospective quality assessment.

OBJECTIVES: Patient and public involvement (PPI) in clinical research has a well-established infrastructure in the UK, and while there has been good progress within pharmaceutical-industry-sponsored research, further improvements are still needed. This review aims to share learnings from quality assessments of historical PPI projects within Pfizer UK to inform future projects and drive PPI progress in the pharmaceutical industry. DESIGN AND SETTING: Internal assessments of Pfizer UK PPI projects were conducted to identify all relevant projects across the medicines development continuum between 2017 and 2021. Five sample projects were developed into case studies. OUTCOME MEASURE: Retrospective quality assessments were performed using the Patient Focused Medicines Development (PFMD) Patient Engagement Quality Guidance (PEQG) tool. Recommendations for improvement were developed. RESULTS: Retrospective case study analysis and quality framework assessment revealed benefits of PPI to both Pfizer UK and to external partners, as well as challenges and learnings to improve future practice. Recommendations for improvement based on these findings focused on processes and procedures for PPI, group dynamics and diversity for PPI activities, sharing of expertise, the importance of bidirectional and timely feedback, and the use of understandable language in materials. CONCLUSIONS: PPI in medicines development is impactful and beneficial but is still being optimised in the pharmaceutical industry. Using the PFMD PEQG tool to define gaps, share learnings and devise recommendations for improvement helps to ensure that PPI is genuine and empowering, rather than tokenistic. Ultimately, these recommendations should be acted on to further embed PPI as an integral part of medicines development and health research within the pharmaceutical industry. This article includes a plain language summary in the supplement.

Aberrant Akt2 signaling in the RPE may contribute to retinal fibrosis process in diabetic retinopathy.

Diabetic Retinopathy (DR) is a complication of diabetes that causes blindness in adults. Retinal fibrosis is closely associated with developing proliferative diabetic retinopathy (PDR). Clinical studies have shown that fibrotic membranes exhibit uncontrolled growth in PDR and contribute to retinal detachment from RPE cells, ultimately leading to vision loss. While anti-VEGF agents and invasive laser treatments are the primary treatments for PDR, retinal fibrosis has received minimal attention as a potential target for therapeutic intervention. Therefore, to investigate the potential role of Akt2 in the diabetes-induced retinal fibrosis process, we generated RPE-specific Akt2 conditional knockout (cKO) mice and induced diabetes in these mice and Akt2fl/fl control mice by intraperitoneal injection of streptozotocin. After an 8-month duration of diabetes (10 months of age), the mice were euthanized and expression of tight junction proteins, epithelial-mesenchymal transition (EMT), and fibrosis markers were examined in the RPE. Diabetes induction in the floxed control mice decreased levels of the RPE tight junction protein ZO-1 and adherens junction proteins occludin and E-cadherin; these decreases were rescued in Akt2 cKO diabetic mice. Loss of Akt2 also inhibited diabetes-induced elevation of RNA and protein levels of the EMT markers Snail/Slug and Twist1 in the RPE as compared to Akt2fl/fl diabetic mice. We also found that in Akt2 cKO mice diabetes-induced increase of fibrosis markers, including collagen IV, Connective tissue growth factor (CTGF), fibronectin, and alpha-SMA was attenuated. Furthermore, we observed that high glucose-induced alterations in EMT and fibrosis markers in wild-type (WT) RPE explants were rescued in the presence of PI3K and ERK inhibitors, indicating diabetes-induced retinal fibrosis may be mediated via the PI3K/Akt2/ERK signaling, which could provide a novel target for DR therapy.

Reducing Akt2 in retinal pigment epithelial cells causes a compensatory increase in Akt1 and attenuates diabetic retinopathy.

The retinal pigment epithelium (RPE) plays an important role in the development of diabetic retinopathy (DR), a leading cause of blindness worldwide. Here we set out to explore the role of Akt2 signaling-integral to both RPE homeostasis and glucose metabolism-to DR. Using human tissue and genetically manipulated mice (including RPE-specific conditional knockout (cKO) and knock-in (KI) mice), we investigate whether Akts in the RPE influences DR in models of diabetic eye disease. We found that Akt1 and Akt2 activities were reciprocally regulated in the RPE of DR donor tissue and diabetic mice. Akt2 cKO attenuated diabetes-induced retinal abnormalities through a compensatory upregulation of phospho-Akt1 leading to an inhibition of vascular injury, inflammatory cytokine release, and infiltration of immune cells mediated by the GSK3ß/NF-κB signaling pathway; overexpression of Akt2 has no effect. We propose that targeting Akt1 activity in the RPE may be a novel therapy for treating DR.
