An experience of multidisciplinary tutorials sessions about antibiotics in the third year of pharmacy studies in Angers, France: learning assessment and evaluation of students' feelings by a mixed approach.

For undergraduate pharmacy students, the first step of antimicrobial stewardship learning objectives is to integrate antimicrobial knowledge from the foundational sciences. We hypothesised that using a multidisciplinary approach including two sessions of tutorials could be relevant in term of students' interest, satisfaction and learning retention time. The evaluation of students' feelings was based on a questionnaire including different dimensions and three focus groups with four students. Quantitative data were analysed with the EPI-INFO 7.2 software and a thematic analysis was implemented for qualitative data by using NVivo 12 software. The evaluation of students' learning concerned both short-time learning retention (STLR) and medium-time learning retention (MTLR), six months after the last session. Overall, 63 students responded to the questionnaire. Most of them appreciated the tutorials according to the different dimensions envisaged. Focus groups confirmed the interest of students for the multidisciplinary approach, interactions with teachers and opportunities of learning transfers. Concurrently, a lack of self-efficacy, low confidence towards the other students, external regulation of motivation and poor autonomy were recorded for some participants. Finally, there was no significant decrease between the scores of the STLR assessment and those of the MTLR assessment (58.5 ± 12.1/100 and 54.4 ± 8.9/100, respectively).

Teaching bacterial infections in pharmaceutical studies: why not 'with students' instead of 'to students'?

In pharmaceutical studies, a course of bacteriology based on case studies provided by the teacher was transformed in a course based on a combination of student/teacher co-creation of cases and peer reviewing. Our objectives were to describe the perception of students about the new format and to assess the impact of changing on the learning outcomes. For teaching evaluation, we used a questionnaire and focus groups. The assessment of learning outcome was performed by comparing the students' scores in final tests with the previous and the revised course formats. The students embraced the creation of cases in small groups with the teacher. In addition, they reported a perception of weakened hierarchy between the teacher and themselves, an increase of their self-confidence and a better ability to transfer their learning to their professional activities in community pharmacies. Lastly, their opinion about the transferability of this format in other disciplines were divided.

Secondary metabolites from lichen as potent inhibitors of advanced glycation end products and vasodilative agents.

Secondary metabolites from lichens are known for exhibiting various biological effects such as anti-inflammatory, antioxidant and antibacterial activities. Despite this wide range of reported biological effects, their impact on the formation of advanced glycation end products (AGEs) remains vastly unexplored. The latter are known contributors to lifestyle and age-related diseases such as Alzheimer and Parkinson. Moreover, the development of atherosclerosis and arterial stiffness is causally linked to the formation of AGEs. With this in mind, the present work evaluated the inhibitory effects of secondary lichen metabolites on the formation of pentosidine-like AGEs' by using an in vitro, Maillard reaction based, fluorescence assay. Overall, thirty-seven natural and five synthetically modified compounds were tested, eighteen of which exhibiting IC50 values in the range of 0.05 to 0.70 mM. This corresponds to 2 to 32 fold of the inhibitory activity of aminoguanidine. Targeting one major inhibiting mechanism of AGEs formation, all compounds were additionally evaluated on their radical scavenging capacities in an DPPH assay. Furthermore, as both AGEs' formation and hypertension are major risk factors for atherosclerosis, compounds that were available in sufficient amounts were also tested for their vasodilative effects. Overall, and though some of the active compounds were previously reported cytotoxic, present results highlight the interesting potential of secondary lichen metabolites as anti-AGEs and vasodilative agents.
