Pharmacy students' use and perceptions of Apple mobile devices incorporated into a basic health science laboratory.

OBJECTIVE: To describe pharmacy students' use of mobile devices in a basic health science laboratory and to report the students' perceptions on how solving cases with their mobile devices influenced their attitudes, abilities, and view on the use of mobile devices as tools for pharmacists. METHODS: First-year pharmacy students utilized mobile devices to solve clinical case studies in a basic health sciences laboratory. A pre-survey and two post-surveys were administered to assess the students' comfort, awareness, use, and perceptions on the use of their mobile devices and apps. RESULTS: The pre-survey and first post-survey each had a response rate of 99%, and the second post-survey had a response rate of 100%. In comparing the pre-survey and first post-survey data, there was a statistically significant increase in the number of students that agreed or strongly agreed that they were more comfortable utilizing their mobile device (p = 0.025), they were more aware of apps for pharmacists (p < 0.005), and they have used more apps that can be useful for pharmacists (p < 0.005). The second post-survey demonstrated that over 78% of students agreed or strongly agreed that completing the case studies influenced them to be more comfortable with their mobile devices, to be more aware of apps that can be useful for pharmacists, and to be more agreeable with mobile device utilization by pharmacists in improving patient care. In addition, the second post-survey also demonstrated that 84% of students responded that using their mobile devices to solve the cases influenced them to either use their mobile device in a clinical setting for a clinical and/or pharmacy-related purpose for the first time or to use it more frequently for this purpose. CONCLUSIONS: The use of mobile devices to solve clinical cases in a first-year basic health science laboratory course was perceived as beneficial by students and influenced them to utilize their mobile device even more in a pharmacy practice setting.

Pharmacy students' preference for using mobile devices in a clinical setting for practice-related tasks.

OBJECTIVE: To examine pharmacy students' ownership of, use of, and preference for using a mobile device in a practice setting. METHODS: Eighty-one pharmacy students were recruited and completed a pretest that collected information about their demographics and mobile devices and also had them rank the iPhone, iPad mini, and iPad for preferred use in a pharmacy practice setting. Students used the 3 devices to perform pharmacy practice-related tasks and then completed a posttest to again rank the devices for preferred use in a pharmacy practice setting. RESULTS: The iPhone was the most commonly owned mobile device (59.3% of students), and the iPad mini was the least commonly owned (18.5%). About 70% of the students used their mobile devices at least once a week in a pharmacy practice setting. The iPhone was the most commonly used device in a practice setting (46.9% of students), and the iPod Touch was the least commonly used device (1.2%). The iPad mini was the most preferred device for use in a pharmacy practice setting prior to performing pharmacy practice-related tasks (49.4% of students), and was preferred by significantly more students after performing the tasks (70.4%). CONCLUSION: Pharmacy students commonly use their mobile devices in pharmacy practice settings and most selected the iPad mini as the preferred device for use in a practice setting even though it was the device owned by the fewest students.

Hyperglycemia enhances function and differentiation of adult rat cardiac fibroblasts.

Diabetes is an independent risk factor for cardiovascular disease that can eventually cause cardiomyopathy and heart failure. Cardiac fibroblasts (CF) are the critical mediators of physiological and pathological cardiac remodeling; however, the effects of hyperglycemia on cardiac fibroblast function and differentiation is not well known. Here, we performed a comprehensive investigation on the effects of hyperglycemia on cardiac fibroblasts and show that hyperglycemia enhances cardiac fibroblast function and differentiation. We found that high glucose treatment increased collagen I, III, and VI gene expression in rat adult cardiac fibroblasts. Interestingly, hyperglycemia increased CF migration and proliferation that is augmented by collagen I and III. Surprisingly, we found that short term hyperglycemia transiently inhibited ERK1/2 activation but increased AKT phosphorylation. Finally, high glucose treatment increased spontaneous differentiation of cardiac fibroblasts to myofibroblasts with increasing passage compared with low glucose. Taken together, these findings suggest that hyperglycemia induces cardiac fibrosis by modulating collagen expression, migration, proliferation, and differentiation of cardiac fibroblasts.

Evaluation of the incorporation of an innovative writing assignment into a physician assistant basic biomedical course.

PURPOSE: The purpose of this study was to evaluate first-year physician assistant (PA) students' attitudes towards an applied writing assignment in a basic biomedical course. METHODS: The assignment required the students to choose a physiology or pathophysiology-related article from a respected media outlet and to select a related original research article. The students summarized, compared, and contrasted the two articles. Finally, the students described how they would explain the media article and related research article to a patient in lay terms that the patient could understand. To evaluate the effectiveness of this assignment the students were given an anonymous survey. RESULTS: The majority of students agreed that this assignment was relevant to their career training, that the articles they chose were related to an interest of theirs, and that they learned new information about health and/or pathophysiology. Students' comments reinforced their perceived significance of this assignment to their career training and roles as future health care professionals. CONCLUSIONS: It can be inferred from this study that PA students found this type of writing assignment helpful for independently learning a course topic of interest and that they found the writing exercise applicable to their future careers.

Cardiac myofibroblast differentiation is attenuated by alpha(3) integrin blockade: potential role in post-MI remodeling.

Cardiac fibroblasts and myofibroblasts are responsible for post-MI remodeling which occurs via regulation of extracellular matrix (ECM). Accelerated post-MI remodeling leads to excessive ECM deposition and fibrosis, contributing to impaired contractile function, arrhythmias, and heart failure. We have previously reported that type VI collagen induces myofibroblast differentiation in cultured cardiac fibroblasts, and that type VI collagen and myofibroblast content were both elevated in the myocardium 20 weeks post-MI. The purpose of this study was to determine the expression patterns of type VI collagen and myofibroblast content in early post-myocardial infarction (MI) remodeling to gain insight into whether type VI collagen induces in vivo myofibroblast differentiation via specific matrix-receptor interactions. Adult male Sprague-Dawley rats were anesthetized and left coronary arteries were permanently ligated. Histological tissue sections and whole tissue protein lysates were obtained from infarcted and non-infarcted areas of MI hearts and sham operated controls. At 3 days post-MI, we observed a significant increase in alpha(3) integrin expression (2.02+/-0.18 fold); at 7 days post-infarction both type VI collagen (2.27+/-0.18 fold) and myofibroblast (4.65+/-0.6 fold) content increased. By 14 days myofibroblast content returned to sham control levels, although type VI collagen (2.42+/-0.11 fold) was still elevated. In vitro cross-linking confirmed that the alpha(3) integrin interacts with type VI collagen, and alpha(3) integrin function blocking antibodies inhibited the differentiation of isolated cardiac fibroblasts. Collectively, our in vitro results indicate that the alpha(3) integrin receptor interacts with type VI collagen to promote myofibroblast differentiation, and that this interaction may impact in vivo post-MI remodeling.
