In this study, we investigated which teaching approach may be optimal to facilitate learning about thermal phenomena in primary school. Concretely, we conducted a pretest-posttest quasi-experiment that included 45 eighth-grade students divided into three groups. In the first group (a non-interactive teacher-centered approach), the teacher gave an experiment-based lecture on converting thermal energy into mechanical work. In the second group (a teacher-centered interactive approach), the teacher gave the same experiments-based lecture, but interacted much more with the students and encouraged them to think about the demonstrations. Finally, in the third group, the student-centered interactive approach was applied. The results of the ANCOVA showed that the three teaching approaches were equally effective in developing students’ understanding of thermal phenomena. However, closer analyses showed that students who learned from the teacher-centered interactive approach significantly outperformed their peers when it came to understanding basic thermal concepts approach, students worked in small groups to conduct the same experiments and “discover” the same relationships that the teacher had introduced in the previous one.

Background: Functional tricuspid valve regurgitation secondary to left-sided valve disease is common. DeVega repair is simple, but residual regurgitation with subsequent impairment of the right ventricular function is a concern. This study aims to compare tricuspid valve repair using DeVega vs. ring annuloplasty and their impact on the right ventricle in the early postoperative period and after six months. Methods: This is a prospective cohort study of 51 patients with rheumatic heart disease who underwent tricuspid valve repair for secondary severe tricuspid regurgitation. Patients were divided into two groups: group A; DeVega repair (n=34) and group B; ring annuloplasty repair (n=17). Patients were assessed clinically and by echocardiography before discharge and after six months for the degree of tricuspid regurgitation, right ventricular diameter and tricuspid annular plane systolic excursion (TAPSE). Results: Preoperative echocardiographic assessment showed no difference in left ventricular end-systolic diameter, end-diastolic diameter, ejection fraction and right ventricular diameter, however; group A had significantly better preoperative right ventricular function measured by TAPSE (1.96 ± 0.27 vs1.75 ± 0.31 cm; p=0.02). Group B had significantly longer cardiopulmonary bypass time (127.65 ± 13.56 vs. 111.74 ± 18.74 minutes; p= 0.003) and ischemic time (99.06 ± 11.80 vs. 87.15 ± 16.01 minutes; p= 0.009). Pre-discharge, there was no statistically significant difference in the degree of tricuspid regurgitation, but the right ventricular diameter was significantly lower in group B (2.66 ± 0.41 and 2.40 ± 0.48 cm; p=0.049). After six months of follow up, the degree of tricuspid regurgitation (p= 0.029) and the right ventricular diameter were significantly lower in the ring annuloplasty group (2.56 ± 0.39 and 2.29 ± 0.44 cm; p=0.029). Although there was a statistically significant difference in preoperative TAPSE, this difference disappeared after six months. Conclusion: Both DeVega and ring annuloplasty techniques were effective in the early postoperative period, ring annuloplasty was associated with lesser residual regurgitation and better right ventricular remodeling in severe functional tricuspid regurgitation than DeVega procedure after 6-months of follow up.

Abstract Introduction Conceptions of learning and teaching refer to what faculty think about teaching effectiveness. Approaches to teaching refer to the methods they use to teach. Both conceptions and approaches range from student-centered/learning-focused (active learner engagement) to teaching-centered/content-focused (passive learner engagement). This study explored how faculty teaching experience influenced faculty conceptions and their approaches to teaching. The authors hypothesized that more experienced educators appreciate and apply active learning approaches. Methods The authors used a cross-sectional survey to collect anonymous data from the Basic Science faculty at Virginia Tech Carilion School of Medicine (VTCSOM). The survey included the Conceptions of Learning and Teaching scale (COLT; Jacobs et al. 2012) and demographic information. They assessed instrument reliability with Cronbach’s alpha and examined relationships between variables with correlation and chi-square and group differences with ANOVA. Results Thirty-eight percent (50/130) of faculty responded to the survey. COLT scores for student-centered (4.06 ± 0.41) were significantly higher (p < 0.001) than teacher-centered (3.12 ± 0.6). Teacher-centered scores were lower (p < 0.05) for younger (30–39, 2.65 ± 0.48) than older faculty (50–59, 3.57 ± 0.71) and were negatively correlated with using multiple teaching methods (p = 0.022). However, 83% (39/50) reported using both traditional lectures and active approaches. Discussion Faculty conceptions about teaching showed appreciation for active learning, but a tendency to use traditional teaching methods interspersed with student-centered ones. Teaching experience was not related to faculty conceptions but was related to their teaching approaches. The amount of time dedicated to teaching was related to the appreciation of active learning, and young teachers were more student-oriented.

Abstract Background This study aims at determining the biological effect of 75/25 w/w nano-hydroxyapatite/chitosan (nHAp/CS) scaffolds on bone regeneration, in terms of fraction of bone regeneration (FBR), total number of osteocytes (Ost), and osteocyte cell density (CD), as well as its biodegradability. Methods Two critical-size defects (CSDs) were bilaterally trephined in the parietal bone of 36 adult Sprague-Dawley rats (18 males and 18 females); the left remained empty (group A), while the right CSD was filled with nHAp/CS scaffold (group B). Two female rats died postoperatively. Twelve, 11, and 11 rats were euthanized at 2, 4, and 8 weeks post-surgery, respectively. Subsequently, 34 specimens were resected containing both CSDs. Histological and histomorphometric analyses were performed to determine the FBR, calculated as [the sum of areas of newly formed bone in lateral and central regions of interest (ROIs)]/area of the original defect, as well as the Ost and the CD (Ost/mm2) in each ROI of both groups (A and B). Moreover, biodegradability of the nHAp/CS scaffolds was estimated via the surface area of the biomaterial (BmA) in the 2nd, 4th, and 8th week post-surgery. Results The FBR of group B increased significantly from 2nd to 8th week compared to group A (P = 0.009). Both the mean CD and the mean Ost values of group B increased compared to group A (P = 0.004 and P < 0.05 respectively). Moreover, the mean value of BmA decreased from 2nd to 8th week (P = 0.001). Conclusions Based on histological and histomorphometric results, we support that 75/25 w/w nHAp/CS scaffolds provide an effective space for new bone formation.

SummaryObjective: The aim of the study was to investigate the use of somatic cell count (SCC) and aerobic bacterial counts as possible tools to choose animals for selective dry cow treatment (DCT) on cow level. Blanket antibiotic DCT is an approved and common method in Germany aimed at increasing the cure rate of existing intramammary infections (IMI) at the time of drying off and decreasing the risk of new infections during the dry period. However, not all animals benefit equally from an antibiotic DCT. Moreover, dairies, consumers and politicians demand a reduction in the use of antibiotics in farm animals. Several criteria for identifying animals which would benefit from antibiotic DCT have been described in the literature. Material and methods: Animals chosen for this investigation were divided into three study groups: Aerobic Count Petrifilm® group A (153 cows), SCC group S (160 cows) and control group C (169 cows). All quarters were treated with an internal teat sealant (ITS) no matter which group the cows belonged to. Results: Group C, in which all cows received an antibiotic DCT, achieved the best results referred to udder health, particularly regarding bacteriological dry period cure. However, the results of the two study groups A and S, in which the animals were dried off selectively, were only marginally worse. A significant difference regarding bacterial dry period cure was revealed between group S and group C (p = 0.039), whereas no significant difference concerning new IMI risk could be detected between the three study groups. Compared to a blanket antibiotic DCT of all cows in the corresponding study group, a reduction of the usage of antibiotics of 23.5 % (A) and 55 % (S) was noticed, respectively. Furthermore, it could be shown that the lactation number as well as the microorganisms present at the time of drying off influence udder health. Conclusion: Selective DCT is an alternative method to the widespread blanket antibiotic DCT. However, it has to be mentioned that selective DCT involves the described marginal decline in udder health and the additional amount of time, which might arise from the procedure of choosing the right animals and performing the applied rapid test methods.
