Cognitive and Emotional Changes in Peer Educators of Type 2 Diabetes Patients After Starting Peer-Support Activities

Background: Diabetes self-management education through peer support has beneficial effects, especially in regions with limited medical resources. To ensure peer educators continue to provide peer-led education programs, it is important that they remain motivated to instruct patients. Here, to explore measures to enhance peer-educators’ motivation toward such programs, we examined the cognitive and emotional changes in Filipino type 2 diabetics after 7-month activities as peer educators. Methods: We individually performed semi-structured interviews with 13 peer educators with 20 years of age or above in August 2017 (immediately before starting their peer-education activities) and in March 2018 (7 months after the start). The first interview was performed after the peer educators had received 2-day training of diabetes self-management. In both interviews, we asked the peer educators about their feelings toward peer-led educational activities (e.g., satisfaction, difficulty, reward, confidence, and challenges). Their replies about their own cognition and emotions were interpreted and integrated, and then analyzed qualitatively. Results: Four and seven categories were extracted from the first and second interviews, respectively. The category “Cognition of patients’ active learning attitudes and of positive changes in patients’ physical conditions and behavior” observed in the second interview led to “Cognition of growth as a peer educator” and “Satisfaction with supporting patients as a peer educator.” These two feelings gave the peer educators’ “Increased motivation to continue the activities as a peer educator.” This motivation was also associated with “Active collaboration among peer educators,” which was affected by “Difficulties and concerns in working as a peer educator.” Conclusion: To sustain diabetic peer-led education programs, we suggest that interventions be implemented that increase peer educators’ motivation toward their activities and stimulate their awareness of the importance of collaborating with one another. Such collaboration should help to overcome the difficulties they may face in providing peer-led education

A Conceptual Model for Quality of Life Among People with Type 2 Diabetes in the Philippines

[Background] The increased prevalence of chronic diseases is a social issue in developing countries. [Methods] To create a conceptual model representing the quality of life of low-income people with type 2 diabetes in the Philippines, 117 low-income adult participants in a public support group were studied, and the Physical Component Summary (PCS) and Mental Component Summary (MCS) scores on quality of life (QOL) were analyzed in terms of their relationships with the following factors: basic attributes, physical factors (glycated hemoglobin level, complications, comorbidities, and symptoms), social factors (support, education, and financial status), and cognitive factors (knowledge, attitude, self-efficacy, and self-management behavior). [Results] Based on correlation coefficients among variables and goodness-of-fit test results through a path analysis, 2 models representing causal relationships were created, both of which showed sufficient goodness-of-fit. [Conclusion] Glycated hemoglobin levels, knowledge of blood glucose levels, self-efficacy, and self-management behavior (exercise) influenced PCS scores, while age, glycated hemoglobin levels, neuropathy, knowledge of insulin, self-efficacy, and self-management behavior (exercise) influenced MCS scores. The influence of self-efficacy was prominent in both cases, providing an important insight for healthcare professionals to develop effective support methods

Effects of a Self-efficacy Theory-Based Training Program for Peers of Patients with Type 2 Diabetes

[Background] Training peer leaders to deliver patient education is expected to be a low-cost approach to providing healthcare in urban-poor areas affected by a shortage of healthcare professionals. The purpose of this study was to examine the effects of a training program on the self-efficacy and knowledge of peer leaders with type 2 diabetes. [Methods] A single-group longitudinal survey with baseline, intervention, and follow-up periods was conducted at a diabetes clinic in a small municipality in Metro Manila, Philippines. The intervention, a self-efficacy theory-based training program for peer-leaders of diabetic patients conducted in August 2017, comprised hands-on learning, demonstrations, quizzes, role-playing, group sharing, physical exercise, and a buffet lunch. The primary outcome was participants’ self-efficacy for management of their diabetes. Secondary outcomes were participants’ knowledge of diabetes and levels of emotional distress, motivation, and confidence for guiding their peers, satisfaction with the training program, hemoglobin A1c, and quality of life. [Results] At 12 and 18 months after the intervention, participants’ knowledge of diabetes was significantly increased compared with baseline (both P < 0.05). At earlier time points, an increasing, but not significant, trend was observed. The change in knowledge of diabetes from baseline to 18 months after intervention tended to be positively correlated with the change in self-efficacy (r = 0.594, P = 0.054). No significant differences were observed for any of the other outcomes, although the descriptive statistics showed an increasing trend for all of the outcomes except motivation. [Conclusion] The training program significantly improved participants’ knowledge of diabetes at 12 and 18 months after the training programs compared with baseline. A positive correlation between the changes in the levels of knowledge and self-efficacy suggested that the observed improvement of self-efficacy was facilitated by the improvement of knowledge of diabetes

Calcium sparks enhance the tissue fluidity within epithelial layers and promote apical extrusion of transformed cells

In vertebrates, newly emerging transformed cells are often apically extruded from epithelial layers through cell competition with surrounding normal epithelial cells. However, the underlying molecular mechanism remains elusive. Here, using phospho-SILAC screening, we show that phosphorylation of AHNAK2 is elevated in normal cells neighboring RasV12 cells soon after the induction of RasV12 expression, which is mediated by calcium-dependent protein kinase C. In addition, transient upsurges of intracellular calcium, which we call calcium sparks, frequently occur in normal cells neighboring RasV12 cells, which are mediated by mechanosensitive calcium channel TRPC1 upon membrane stretching. Calcium sparks then enhance cell movements of both normal and RasV12 cells through phosphorylation of AHNAK2 and promote apical extrusion. Moreover, comparable calcium sparks positively regulate apical extrusion of RasV12-transformed cells in zebrafish larvae as well. Hence, calcium sparks play a crucial role in the elimination of transformed cells at the early phase of cell competition

The Principle of Minimum Differentiation Revisited: Return of the Median Voter *

We study a linear location model (Hotelling, 1929) in which n (with n ≥ 2) boundedly rational players follow (noisy) myopic best-reply behavior. We show through numerical and mathematical analysis that such players spend almost all the time clustered together near the center, re-establishing the " Principle of Minimum Differentiation " that had been discredited by equilibrium analyses. Thus, our analysis of the best-response dynamics shows that when considering market dynamics as well as their policy and welfare implications, it may be important to look beyond equilibrium analyses
