Background and objectiveStress and burnout impact resident physicians. This prospective study tests the hypothesis that a mindfulness-based resilience intervention would decrease stress and burnout in residents.MethodsResident physicians from the Departments of Family Medicine, Psychiatry, and Anesthesia at Duke University, Durham, NC, USA, participated in two or three 1-hour sessions of mindfulness-based resilience activities, which introduced mindful-awareness and included practical exercises for nurturing resilience. Anonymous surveys were distributed before (completed by 47 residents) and after the intervention (both completed by 30 residents); a follow-up survey was distributed 1 month later (seven residents completed all three surveys). The survey included the Depression Anxiety Stress Scale, 21-question version (DASS-21), the Oldenburg Burnout Inventory, the Mindful Attention Awareness Scale, and ten questions from the Cognitive Failures Questionnaire.ResultsAt baseline, most residents’ scores were in the normal range with respect to stress; however, female residents had higher DASS-21 scores than male residents (31.7, females vs 18.4, males; P=0.002). Most residents’ burnout scores were in the abnormal range, both with respect to exhaustion (38/47 residents, subscore ≥2.25) and disengagement (37/47 residents, subscore ≥2.1). Higher perceived levels of stress correlated with the instruments. Analysis of the surveys before and after the intervention showed no significant short-term change in stress, burnout, mindful-awareness, or cognitive failure. There was a trend for females and post-medical school graduate year 1 and 2 (PGY1 and PGY2) residents to have a reduction in DASS-21 scores after intervention. There was also a trend of reduced stress and burnout in residents who perceived higher stress.ConclusionResidents who are female, PGY1 and PGY2, and who perceive residency to be stressful may benefit most from a mindfulness-based resilience intervention.

BackgroundPatient education materials should be written at a level that is understandable for patients with low health literacy. The aims of this study are (1) to review the literature on readability of ophthalmic patient education materials and (2) to evaluate and revise our institution’s patient education materials about glaucoma using evidence-based guidelines on writing for patients with low health literacy.MethodsA systematic search was conducted on the PubMed/MEDLINE database for studies that have evaluated readability level of ophthalmic patient education materials, and the reported readability scores were assessed. Additionally, we collected evidence-based guidelines for writing easy-to-read patient education materials, and these recommendations were applied to revise 12 patient education handouts on various glaucoma topics at our institution. Readability measures, including Flesch-Kincaid Grade Level (FKGL), and word count were calculated for the original and revised documents. The original and revised versions of the handouts were then scored in random order by two glaucoma specialists using the Suitability Assessment of Materials (SAM) instrument, a grading scale used to evaluate suitability of health information materials for patients. Paired t test was used to analyze changes in readability measures, word count, and SAM score between original and revised handouts. Finally, five glaucoma patients were interviewed to discuss the revised materials, and patient feedback was analyzed qualitatively.ResultsOur literature search included 13 studies that evaluated a total of 950 educational materials. Among the mean FKGL readability scores reported in these studies, the median was 11 (representing an eleventh-grade reading level). At our institution, handouts’ readability averaged a tenth-grade reading level (FKGL = 10.0 ± 1.6), but revising the handouts improved their readability to a sixth-grade reading level (FKGL = 6.4 ± 1.2) (p < 0.001). Additionally, the mean SAM score of our institution’s handouts improved from 60 ± 7 % (adequate) for the original versions to 88 ± 4 % (superior) for the revised handouts (p < 0.001).ConclusionsOur systematic review of the literature reveals that ophthalmic patient education materials are consistently written at a level that is too high for many patients to understand. Our institution’s experience suggests that applying guidelines on writing easy-to-understand material can improve the readability and suitability of educational materials for patients with low health literacy.

Increasing evidence suggests that cytokines such as interleukin-1beta (IL-1), IL-4, and IL-8 may play an important role in the chronic inflammation and cellular growth observed in cardiovascular diseases. The lipoxygenase (LO) pathway of arachidonate metabolism has also been related to the pathology of hypertension and atherosclerosis. LO products have chemotactic, hypertrophic, and mitogenic effects in vascular cells, and the LO enzyme has been implicated in the oxidation of LDL. Furthermore, earlier studies have shown that vascular smooth muscle cell (VSMC) growth factors such as angiotensin II and platelet-derived growth factor can increase LO activity and expression in VSMCs. In the present study, we have examined whether vasoactive and inflammatory cytokines such as IL-1, IL-4, and IL-8 can modulate 12-LO activity and expression in porcine VSMCs and also whether they have growth-promoting effects in these cells. Treatment of porcine VSMCs with these cytokines led to significant increases in the levels of a cell-associated 12-LO product, 12-hydroxyeicosatetraenoic acid, as well as intracellular 12-LO enzyme activity. Furthermore, each of these cytokines led to a dose-dependent increase in 12-LO mRNA expression (333-base pair PCR product) as well as 12-LO protein expression (72 kD). In addition, all three interleukins could induce significant increases in VSMC DNA synthesis as well as proliferation. These results suggest that these cytokines have mitogenic effects in VSMCs and are also potent positive regulators of the 12-LO pathway. Thus, enhanced 12-LO activity and expression may be a key mechanism for cytokine-induced VSMC migration and proliferation.
