Introduction: Patient education is an essential element of the treatment pathway. Augmented reality (AR), with disease simulations and three-dimensional visuals, offers a developing approach to patient education. We aim to determine whether this tool can increase patient understanding of their disease and post-visit satisfaction in comparison to current standard of care (SOC) educational practices in a randomized control study. Methods: Our single-site study consisted of 100 patients with initial diagnoses of kidney masses or stones randomly enrolled in the AR or SOC arm. In the AR arm, a physician used AR software on a tablet to educate the patient. SOC patients were educated through traditional discussion, imaging, and hand-drawn illustrations. Participants completed pre- and post-physician encounter surveys adapted from the Press Ganey® patient questionnaire to assess understanding and satisfaction. Their responses were evaluated in the Readability Studio® and analyzed to quantify rates of improvement in self-reported understanding and satisfaction scores. Results: There was no significant difference in participant education level (P = 0.828) or visit length (27.6 vs. 25.0 min, P = 0.065) between cohorts. Our data indicate that the rate of change in pre- to post-visit self-reported understanding was similar in each arm (P ≥ 0.106 for all responses). The AR arm, however, had significantly higher patient satisfaction scores concerning the educational effectiveness and understanding of images used during the consultation (P < 0.05). Conclusions: While AR did not significantly increase self-reported patient understanding of their disease compared to SOC, this study suggests AR as a potential avenue to increase patient satisfaction with educational tools used during consultations.
Borate transporters are membrane transport proteins that regulate intracellular borate levels. In plants, borate is a micronutrient essential for growth but is toxic in excess, while in yeast, borate is unnecessary for growth and borate export confers tolerance. Borate transporters share structural homology with human bicarbonate transporters in the SLC4 family despite low sequence identity and differences in transported solutes. Here, we characterize the S. cerevisiae borate transporter Bor1p and examine whether key biochemical features of SLC4 transporters extend to borate transporters. We show that borate transporters and SLC4 transporters share multiple properties, including lipid-promoted dimerization, sensitivity to stilbene disulfonate-derived inhibitors, and a requirement for an acidic residue at the solute binding site. We also identify several amino acids critical for Bor1p function and show that disease-causing mutations in human SLC4A1 will eliminate in vivo function when their homologous mutations are introduced in Bor1p. Our data help elucidate mechanistic features of Bor1p and reveal significant functional properties shared between borate transporters and SLC4 transporters.
