The impact of two longitudinal professionalism courses on student pharmacistsā empathy
Objective. To determine whether empathy increased in first-year student pharmacists after completing longitudinal professionalism courses at two schools of pharmacy, identify potential moderators, and assess whether studentsā conceptualization of empathy changed with time. Methods. Surveys to assess empathy and other variables were administered to student pharmacists at baseline and at the end of two professionalism courses. Baseline and follow-up scores were compared to detect changes over time. Multivariable analysis was used to identify predictors of empathy scores. Factor analysis was performed to ascertain changes in the dimensionality of empathy. Results. Studentsā demographics and baseline empathy scores differed between the two schools. Pre-dictors of empathy at baseline included age, female gender, prior health care experience, and altruism score. A small increase in empathy was observed at one school but not in the combined cohort. Empathy was more likely to increase among female students, those with less health care experience, and those who did not work during the school year. Factor analyses suggested that studentsā conceptual clarity about empathy improved over time and became more consistent with existing models. Conclusion. Although an increase in empathy was not observed in the overall cohort, subgroups of students who may derive greater benefit from empathy-related interventions were identified. Factor analyses suggested that studentsā conceptual understanding of empathy improved, representing a potential alternative outcome assessment for affective domains. Given differences in demographics, instructional methodologies, and changes in empathy at each school, this study reinforces the importance of replication and multicenter studies to understand the generalizability of educational research
Herbal Product Use Among Anticoagulation Patients
Warfarin interacts with many conventional drug products and herbal products,1-3 Given the incompleteness of information on drug-herbal product interactions and the potential for health care practitioners to be unaware of their patients\u27 utilization of herbal products, we surveyed the use of such products among patients receiving warfarin through an anticoagulation clinic. Patients at the University of Maryland Medical System Anticoagulation Clinic were asked to complete an anonymous written questionnaire during their regularly scheduled appointments over one month

Imagining the impossible before breakfast: the relation between creativity, dissociation, and sleep
Dissociative symptoms have been related to higher rapid eye movement sleep density, a sleep phase during which hyperassociativity may occur. This may enhance artistic creativity during the day. To test this hypothesis, we conducted a creative photo contest to explore the relation between dissociation, sleep, and creativity. During the contest, participants (N = 72) took one photo per day for five consecutive days, based on specific daily themes (consisting of single words) and the instruction to take as creative a photo as possible each day. Furthermore, they completed daily measures of state dissociation and a short sleep diary The photos and their captions were ranked by two professional photographers and two clinical psychologists based on creativity, originality, bizarreness, and quality. We expected that dissociative people would rank higher in the contest compared with low-dissociative participants, and that the most original photos would be taken on days when the participants scored highest on acute dissociation. We found that acute dissociation predicted a higher ranking on creativity. Poorer sleep quality and fewer hours of sleep predicted more bizarreness in the photos and captions. None of the trait measures could predict creativity. In sum, acute dissociation related to enhanced creativity. These findings contribute to our understanding of dissociative symptomatology
An Investigation into the Protein Composition of the Teneral Glossina morsitans morsitans Peritrophic Matrix.
BACKGROUND
Tsetse flies serve as biological vectors for several species of African trypanosomes. In order to survive, proliferate and establish a midgut infection, trypanosomes must cross the tsetse fly peritrophic matrix (PM), which is an acellular gut lining surrounding the blood meal. Crossing of this multi-layered structure occurs at least twice during parasite migration and development, but the mechanism of how trypanosomes do so is not understood. In order to better comprehend the molecular events surrounding trypanosome penetration of the tsetse PM, a mass spectrometry-based approach was applied to investigate the PM protein composition using Glossina morsitans morsitans as a model organism.
METHODS
PMs from male teneral (young, unfed) flies were dissected, solubilised in urea/SDS buffer and the proteins precipitated with cold acetone/TCA. The PM proteins were either subjected to an in-solution tryptic digestion or fractionated on 1D SDS-PAGE, and the resulting bands digested using trypsin. The tryptic fragments from both preparations were purified and analysed by LC-MS/MS.
RESULTS
Overall, nearly 300 proteins were identified from both analyses, several of those containing signature Chitin Binding Domains (CBD), including novel peritrophins and peritrophin-like glycoproteins, which are essential in maintaining PM architecture and may act as trypanosome adhesins. Furthermore, 27 proteins from the tsetse secondary endosymbiont, Sodalis glossinidius, were also identified, suggesting this bacterium is probably in close association with the tsetse PM.
CONCLUSION
To our knowledge this is the first report on the protein composition of teneral G. m. morsitans, an important vector of African trypanosomes. Further functional analyses of these proteins will lead to a better understanding of the tsetse physiology and may help identify potential molecular targets to block trypanosome development within the tsetse
Global health learning outcomes in pharmacy students completing international advanced pharmacy practice experiences
Ā© 2020, American Association of Colleges of Pharmacy. All rights reserved. Objective. To examine the global health learning outcomes of Doctor of Pharmacy (PharmD) students from three US schools who participated in international advanced pharmacy practice experiences (APPEs). Methods. A mixed-methods, prospective study was used to assess fourth-year PharmD students at three US pharmacy schools who participated in an international APPE during the 2017-2018 academic year and a matched cohort (control group) of PharmD students who did not participate in an international APPE. To evaluate studentsā self-perceived growth in the Consortium of Universities for Global Health (CUGH) competencies, all students completed a 13-item retrospective pre-post instrument using a five-point Likert scale. The students who had completed an international APPE were invited to participate in a focus group (N522). Paired and independent t tests and multiple linear regression were used to analyze data. Qualitative open-ended questions and focus group data were mapped to knowledge, skills, and attitudes themes. Results. The students who completed an international APPE (N581) showed significantly more growth in CUGH competencies than students who did not (mean improvement in total score of 10.3 [7.0] vs 2.4 [6.0]). International APPE participation was the only significant predictor of growth in CUGH competencies. The international APPE students reported improvements in cultural awareness and appreciation, communication skills, problem-solving skills, adaptability, self-awareness, personal and professional outlook, and global health perspective. Conclusion. Pharmacy studentsā participation in international APPEs led to significant improvement in all CUGH competencies. The CUGH competency framework appears to be a suitable instrument to assess pharmacy studentsā global health learning outcomes
Global health learning outcomes by country location and duration for international experiences
Ā© 2020 American Association of Colleges of Pharmacy. Objective. To determine the impact of country income classification and experience duration on learning outcomes for student pharmacists participating in international advanced pharmacy practice experiences (APPEs). Methods. A mixed-methods, longitudinal study evaluated 81 fourth-year student pharmacists participating in an international APPE through one of three US universities. A pre-post survey was administered to evaluate studentsā self-perceived growth across 13 competencies established by the Consortium of Universities for Global Health (CUGH). The survey included four additional open-ended questions. Student pharmacists were also invited to participate in a focus group. Paired and independent t tests and multiple linear regression were conducted. Qualitative survey and focus group data underwent a two-cycle, open-coding process using conventional content analysis. Results. Students who completed their APPE in a low-to middle-income country had greater growth in all CUGH competency statements compared to those who completed their APPE in a high-income country. Completing the APPE in a low-to middle-income country and prior travel for non-vacation purposes were significant predictors of student growth. Students who went to a low-to middle-income country demonstrated increased cultural sensitivity, more patient-centered care, and skill development, while students who went to a high-income country displayed increased knowledge regarding differ-ences in health care system components, pharmacy practice, pharmacy education, and an appreciation for alternative patient care approaches. Conclusion. Learning outcomes differed between students who completed an APPE in a high-income rather than a low-to middle-income country, with both types of locations providing valuable educational opportunities and professional and personal development
Texture Stationarization: Turning Photos into Tileable Textures
Texture synthesis has grown into a mature field in computer graphics, allowing the synthesis of naturalistic textures and images from photographic exemplars. Surprisingly little work, however, has been dedicated to synthesizing tileable textures, that is, textures that when laid out in a regular grid of tiles form a homogeneous appearance suitable for use in memory-sensitive real-time graphics applications. One of the key challenges in doing so is that most natural input exemplars exhibit uneven spatial variations that, when tiled, show as repetitive patterns. We propose an approach to synthesize tileable textures while enforcing stationarity properties that effectively mask repetitions while maintaining the unique characteristics of the exemplar. We explore a number of alternative measures for texture stationarity and show how each measure can be integrated into a standard texture synthesis method (PatchMatch) to enforce stationarity at user-controlled scales. We demonstrate the efficacy of our approach using a database of 118 exemplar images, both from publicly available sources as well as new ones captured under uncontrolled conditions, and we quantitatively analyze alternative stationarity measures for their robustness across many test runs using different random seeds. In conclusion, we suggest a novel synthesis approach that employs local histogram matching to reliably turn input photographs of natural surfaces into tiles well suited for artifact-free tiling
Schizotypy and performance on an insight problem-solving task: The contribution of persecutory ideation
Insight problem solving is thought to underpin creative thought as it incorporates both divergent (generating multiple ideas and solutions) and convergent (arriving at the optimal solution) thinking approaches. The current literature on schizotypy and creativity is mixed and requires clarification. An alternate approach was employed by designing an exploratory web-based study using only correlates of schizotypal traits (paranoia, dissociation, cognitive failures, fantasy proneness, and unusual sleep experiences) and examining which (if any) predicted optimal performance on an insight problem-solving task. One hundred and twenty-one participants were recruited online from the general population and completed the number reduction task. The discovery of the hidden rule (HR) was used as a measure of insight. Multivariate logistic regression analyses highlighted persecutory ideation to best predict the discovery of the HR (OR = 1.05; 95% CI 1.01ā1.10, p = 0.017), with a one-point increase in persecutory ideas corresponding to the participant being 5% more likely to discover the HR. This result suggests that persecutory ideation, above other schizotypy correlates, may be involved in insight problem solving
