Personalized strategies for academic success in learning anatomy: Exploring metacognitive and technological adaptation in medical students.

Personalization of learning is an educational strategy rooted in metacognition and is significant in academic training. This is especially true in medical contexts. This study explored the relationship between the metacognitive profile of students of human anatomy, the classification of questions according to their difficulty, and the anatomical domain. It also covered the integration of educational technologies to create personalized learning environments. The identification of metacognitive profiles ("Active", "Pragmatic", "Theoretical", and "Reflective") has been highlighted as a critical influence on students' responses to different pedagogical approaches. Personalized adaptation based on these profiles has shown potential for improving grades and increasing student satisfaction and engagement with learning. The results revealed variations in student performance in relation to different pedagogical approaches, learning units, and evaluation modalities. The "Experience" evaluation modality, personalized according to metacognitive profiles, level of competence, and learning objectives, resulted in higher average scores. However, there was significant variability in the results. Those findings confirm the effectiveness of metacognitive adaptation in improving academic performance. Furthermore, they provide a solid basis for formulating personalized and effective pedagogical strategies in medical education. They recognize the influence of metacognitive profiles on student performance and contribute to advancing medical pedagogy.

Neurological monitoring reduces the incidence of bortezomib-induced peripheral neuropathy in multiple myeloma patients.

Bortezomib (BTZ) is a proteasome inhibitor approved in the treatment of multiple myeloma (MM). Bortezomib-induced peripheral neuropathy (BIPN) is an unpredictable dose-limiting adverse event in one-third of patients. In the present study, 58 relapsed/refractory MM patients treated with BTZ were analyzed. The study's aim was to compare BIPN incidence and severity between both groups and to identify risk factors of BIPN. Twenty-four MM patients were evaluated by a neurologist periodically during BTZ treatment in order to prevent high-grade BIPN. Thirty-five MM patients previously treated with BTZ were reviewed. Seven (29%) patients in the monitored group and 19 (56%) in the historical cohort developed BIPN (p = 0.044). In the univariate analysis, factors related to BIPN in the whole series were age, number of vincristine and BTZ cycles, lactate dehydrogenase and neurological monitoring. Multivariate analysis revealed that absence of neurological monitoring (Hazard Ratio [HR]: 4.94 IC 95% [1.31-18.68], p = 0.019) and prior treatment with vincristine (HR: 1.34 IC 95% [1.04-1.74], p = 0.026) were associated with greater risk of BIPN. Baseline total neuropathy score-clinical version (TNSc) was a good predictor of BIPN, with higher risk for patients with TNSc >2 (p = 0.038). Neurological monitoring is useful for diminishing BIPN. Neurological monitoring of patients with baseline TNSc >2 should be considered.

Immunohistochemical localization of the sigma1 receptor in Schwann cells of rat sciatic nerve.

The sigma-1 (sigma(1)) receptors can bind different psychotropic drugs and have been implicated in schizophrenia, depression and dementia. The cloning of the sigma(1)-receptor has allowed to obtain specific antibodies and, in a recent immunohistochemical study, we demonstrated that, in addition to neurons, the sigma(1)-receptor is located in oligodendrocytes [Brain Res. 961 (2003) 92.]. In the present study using in vivo and in vitro techniques, we demonstrate the localization of the sigma(1)-receptor in Schwann cells. Double immunofluorescence studies showed that sigma(1)-receptor co-localized with S100 protein, a specific marker of Schwann cells, in both rat sciatic nerve Schwann cells and Schwann cells in cultures. The sigma(1)-receptor immunoreactivity was seen in the cytoplasm and paranodal region formed by these cells, but not in myelin itself. The presence of sigma(1)-receptor in oligodendrocytes and Schwann cells is discussed on the basis on recent findings involving this receptor in lipid metabolism, compartmentalization and transport to the plasma membrane, thus suggesting a role for sigma(1)-receptor signaling in myelination.
