Introduction: The objectives of this comparative study were 1) to compare the effectiveness of in-person classroom instruction versus an online video for teaching literature searching skills to graduate students, and 2) to evaluate their perceptions of the instruction methods received and their instruction preferences for learning literature searching skills. Methods: Students enrolled in a translational medicine graduate course in Fall 2022 were invited to participate in the study. Participants were randomly assigned to a control group (receiving in-person instruction) or to an intervention group (receiving a link to a narrated PowerPoint video). Using Qualtrics online survey tool, participants completed one pre-test and two post-tests to assess learning and retention, and a survey to evaluate their perceptions and attitudes. Results: 12 out of 17 students participated. Both instruction methods were effective for delivering this information literacy content. The in-person group improved more than the online video group from pre- to post-test 1 and from pre- to post-test 2, but the difference was not statistically significant. However, the online video group rated the pace, perceived effectiveness, and clarity of library instruction, and their confidence to perform specific search tasks, more favourably than the in-person group, although the difference was not significant. Participants valued being able to access library training on their own schedule most of all. Discussion: The sample size for this study was small, making it difficult for differences to attain statistical significance. Creating an online video to deliver this content ended up being very time-intensive compared to providing synchronous instruction.

The general implications of AI for libraries are much discussed in library literature. But while this discussion takes place at the library-wide level, there are also important implications for subject librarians due to the specific uses of AI in different professions and areas of study. These are often overlooked as these specializations tend to publish in subject-specific journals. This article aims to address this research gap by providing a comparison and thematic analysis of this literature. Subject-specific library journals in the areas of law, health sciences, business, and humanities and social sciences were searched to identify relevant journal articles that discussed AI. 131 articles were identified and tagged with at least one category that reflected the nature of the discussion around AI. The following analysis showed that literature related to law had the greatest number of articles by far, though the publishing activity in all disciplines has increased significantly in the last 10 years. This article explores these trends to gain a more comprehensive understanding of the implications for subject-specific library work.

Vitamin D has been shown to have multiple pleiotropic effects beyond bone and mineral metabolism, with purported roles in cardiovascular disease, cancer, and host immunity. Vitamin D deficiency is common in patients with end-stage kidney disease (ESKD); however, current clinical practice has favored the use of the active hormone. Whether vitamin D deficiency should be corrected in patients with ESKD remains unclear, as few randomized trials have been conducted. In this systematic review, we summarize the current evidence examining whether vitamin D supplementation improves outcomes, beyond mineral metabolism, in patients with ESKD. Data from randomized controlled trials of adults with ESKD were obtained by searching Ovid MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and the Web of Science Core Collection from inception to February 2023. Twenty-three trials composed of 2489 participants were identified for inclusion. Data were synthesized by two independent reviewers and summarized in tables organized by outcome. Outcomes included measures of mortality, cardiovascular disease, inflammation, muscle strength/function, nutrition, patient well-being, and outcomes specific to ESKD including erythropoietin usage, pruritus, and dialysis access maturation. The Cochrane risk of Bias Tool (RoB 2, 2019) was used to assess study quality. Overall, our findings indicate a minimal and varied benefit of native vitamin D supplementation. From the largest studies included, we determine that vitamin D has no demonstrated effect on patient-reported measures of well-being or utilization of erythropoietin, nor does it change levels of the inflammation biomarker C-reactive protein. Included trials were heterogeneous with regards to outcomes, and the majority studied small participant populations with a relatively short follow-up. We conclude that vitamin D supplementation corrects vitamin D deficiency and is safe and well-tolerated in humans with ESKD. However, it is not clear from clinical trials conducted to date that a causal pathway exists between 25(OH)D and pleiotropic effects that is responsive to vitamin D treatment.
