We aimed to determine whether red cell distribution width (RDW) and mean platelet volume (MPV) values differ between patients with reactive amyloid A (AA) amyloidosis due to chronic inflammatory disease and in healthy participants. In this study, 33 patients with AA amyloidosis and 40 age- and sex-matched healthy controls were enrolled. Erythrocyte sedimentation rate (ESR), RDW, platelet count (PLT), and MPV levels were retrospectively obtained from our computerized patient database. We found RDW, ESR, and PLT levels to be significantly higher in patients with AA amyloidosis compared with the controls (P < .0001). Mean platelet volume was significantly lower in patients with amyloidosis (P < .0001). Inflammatory diseases such as AA amyloidosis may demonstrate low MPV and high RDW levels.

Interest in virtual reality technologies has increased significantly in recent years, and an effort is being made to integrate it into educational environments. This study aims to investigate the impact of synchronous distance courses in the Virtual Reality (VR) learning environment (via vAcademia) and Web-based (via Adobe Connect) learning environment on undergraduate students' learning motivation and levels of perceived sociability. The sample of the study was conducted with experimental (VR) and control group (Web-based) quasi-experimental design consists of 41 undergraduate students (experimental: 21, control: 20). As a result of the t-test and two-way ANOVA analysis, there was a significant difference between the groups in favor of the VR group regarding motivation and perceived sociability. The motivation and perceived sociability in the 3D VR environment of the students in distance learning were significantly higher than in the web-based environment. It was also found out that students' motivation and perceived sociability levels did not vary depending on gender or on the technological device (smartphone or computer) that students use when connecting to online classes. The research results indicated that the VR learning environment effectively ensured students' motivation and sociability in the distance learning process. In this context, institutions should be aware of the importance of VR technologies and plan to teach accordingly which may make the process more efficient.
