In light of the current shifts in medical education from traditional lectures to more active teaching modalities, a peer‐teaching program was introduced to a compulsory, second‐year neuroanatomy course. A cross‐sectional survey of 527 medical students in the six‐year medical program of the National and Kapodistrian University of Athens was administered. The primary aim of the survey, which was distributed to second‐ through sixth‐year medical students, who had completed the neuroanatomy course, was to assess student perception of peer teachers (PTs). Across the five years assessed, students increasingly acknowledged the contribution of PTs to their learning (P < 0.001). Attributes of PTs (e.g., contribution to learning, motivation, effective usage of material, and team environment) were significantly related to the student's opinion of the importance of laboratory activities (P < 0.001). Students who received “average” final grades scored the importance of laboratory exercises, and by inference PTs, significantly lower than students who received “excellent” final grades (P < 0.05). The amount of training that PTs had received was also significantly related to student perceptions of a PT's contribution. Better trained PTs were associated with significantly higher scores regarding learning, motivation, and positive environment compared to less trained PTs (P < 0.05). The results of the present study show that peer‐teaching was well received by students attending the neuroanatomy course. While the results express the evolution of the program across the years, the findings also show that learners believed that PTs and the laboratory program contributed significantly to their understanding of neuroanatomy.
Background: The role of cardiopulmonary exercise testing (CPET) in the assessment of prognosis in CF (cystic fibrosis) is crucial. However, as the overall survival of the disease becomes better, the need for examinations that can predict pulmonary exacerbations (PEx) and subsequent deterioration becomes evident. Methods: Data from a 10-year follow up with CPET and spirometry of CF patients were used to evaluate whether CPET-derived parameters can be used as prognostic indexes for pulmonary exacerbations in patients with CF. Pulmonary exacerbations were recorded. We used a survival analysis through Cox Regression to assess the prognostic role of CPET parameters for PeX. CPET parameters and other variables such as sputum culture, age, and spirometry measurements were tested via multivariate cox models. Results: During a 10-year period (2009–2019), 78 CF patients underwent CPET. Cox regression analysis revealed that VO2peak% (peak Oxygen Uptake predicted %) predicted (hazard ratio (HR), 0.988 (0.975, 1.000) p = 0.042) and PetCO2 (end-tidal CO2 at peak exercise) (HR 0.948 (0.913, 0.984) p = 0.005), while VE/VO2 and (respiratory equivalent for oxygen at peak exercise) (HR 1.032 (1.003, 1.062) p = 0.033) were significant predictors of pulmonary exacerbations in the short term after the CPET. Additionally, patients with VO2peak% predicted <60% had 4.5-times higher relative risk of having a PEx than those with higher exercise capacity. Conclusions: CPET can provide valuable information regarding upcoming pulmonary exacerbation in CF. Patients with VO2peak <60% are at great risk of subsequent deterioration. Regular follow up of CF patients with exercise testing can highlight their clinical image and direct therapeutic interventions.
