“混合式教学+医学教育”实现教学评价研究

教学评价是教学过程中不可或缺的,行之有效的教学评价是促进教学方法改革,增强教学效果的指挥棒。与传统的教学方法相比较在混合式医学教学课堂中,教学评价也应进行相应的改革,从教师、自身、同行三个维度研究混合式医学教学中的教学评价方法的改革。同时强调完善教学评价的反馈机制。通过学生反馈、专家反馈、同行反馈、自身反馈,建立完整的混合式教学+医学教育的教学评价体系。

Pseudoquistes abdominales,una complicación rara de los sistemas de derivación ventrículo-peritoneal: revisión sistemática de la literatura

Since the first report in 1954, abdominal pseudocysts have been recognized as a particularly uncommon complication of ventriculoperitoneal shunts of CSF, so their etiology, diagnosis, and therapeutic management remain very controversial.Our objective is to offer a critical and updated systematic review of those controversial points, using a thorough search and review of the most relevant literature available.The clinical presentation of pseudocysts is normally through non-specific abdominal symptoms. The most validated etiology consists on the existence of a concomitant infection of the CSF shunt system, and so, treatment needs of antibiotherapy and total or partial substitution of the system. However, the pseudocyst itself doesn’t need an active treatment, except for some specific cases. This management, algorithmically presented in the present work, achieves a lower recurrence rate than other options, but this one is still important, and is also associated with other complications of those shunts related with several other factors which need to be taken in account.     

Current thinking in the management of adenoid cystic carcinoma of the head and neck

Adenoid cystic carcinoma (ACC) is an aggressive, rare, malignant tumour that accounts for about 1% of all head and neck neoplasms and 10% of all salivary gland tumours. It is characterised by frequent local recurrences and distant metastases. Growth is slow but relentless, and progression poses a challenge to head and neck clinicians. Many small retrospective studies have described its clinical management, but the lack of multicentre, randomised, controlled trials has resulted in inconsistencies in management globally. We have focused on three key management-related controversies: the role of elective neck dissection (END) for the N0 neck; the role of adjuvant treatment or radiotherapy; and finally, the follow-up protocol, particularly cross-sectional surveillance imaging of the full body or chest computed tomography (CT) alone, and options for treatment if metastases are found. The paucity of published studies may reflect the inconsistencies that exist in the management of ACC of the head and neck in the UK. The collaboration of head and neck centres would, we think, help to correct the imbalance in these three domains of care.     

Predictions of genotoxic potential,mode of action,molecular targets,and potency via a tiered multiflow® assay data analysis strategy

The in vitro MultiFlow® DNA Damage Assay multiplexes γH2AX, p53, phospho-histone H3, and polyploidization biomarkers into a single flow cytometric analysis. The current report describes a tiered sequential data analysis strategy based on data generated from exposure of human TK6 cells to a previously described 85 chemical training set and a new pharmaceutical-centric test set (n = 40). In each case, exposure was continuous over a range of closely spaced concentrations, and cell aliquots were removed for analysis following 4 and 24 hr of treatment. The first data analysis step focused on chemicals' genotoxic potential, and for this purpose, we evaluated the performance of a machine learning (ML) ensemble, a rubric that considered fold increases in biomarkers against global evaluation factors (GEFs), and a hybrid strategy that considered ML and GEFs. This first tier further used ML output and/or GEFs to classify genotoxic activity as clastogenic and/or aneugenic. Test set results demonstrated the generalizability of the first tier, with particularly good performance from the ML ensemble: 35/40 (88%) concordance with a priori genotoxicity expectations and 21/24 (88%) agreement with expected mode of action (MoA). A second tier applied unsupervised hierarchical clustering to the biomarker response data, and these analyses were found to group certain chemicals, especially aneugens, according to their molecular targets. Finally, a third tier utilized benchmark dose analyses and MultiFlow biomarker responses to rank genotoxic potency. The relevance of these rankings is supported by the strong agreement found between benchmark dose values derived from MultiFlow biomarkers compared to those generated from parallel in vitro micronucleus analyses. Collectively, the results suggest that a tiered MultiFlow data analysis pipeline is capable of rapidly and effectively identifying genotoxic hazards while providing additional information that is useful for modern risk assessments—MoA, molecular targets, and potency.

Impact of Spinal Manipulation on Lower Extremity Motor Control in Lumbar Spinal Stenosis Patients: A Small-Scale Assessor-Blind Randomized Clinical Trial

ObjectiveThe purpose of this study was to quantify the impact of a single lumbar spinal manipulation (SM) intervention on the leg movement performance of degenerative lumbar spinal stenosis (LSS) patients in a small-scale registered randomized clinical trial.MethodsParticipants with LSS (n = 14) were tested at baseline for pain, lumbar range of motion, and behavioral or kinematic motor performance (using an established Fitts’ Law foot-pointing task), then underwent covariate adaptive randomization to receive SM or no intervention. Postintervention all dependent measures were repeated. Experimenters were blinded to patient group allocation. University ethics board approval was attained.ResultsFor the primary outcome movement time, there was no significant difference between groups. As predicted by Fitts’ Law, all participants had longer movement times as task difficulty increased. Secondary kinematic outcomes yielded no significant between-group differences. Consistent with Fitts’ Law, kinematic measures changed significantly with task difficulty. Pairwise comparisons revealed the kinematic variables were more adversely affected by greater movement amplitudes than target size changes. No exploratory differences in pain or lumbar range of motion were observed.ConclusionChanges in motor performance were not observed in this chronic pain population after a single SM intervention compared with a control group. Given the sample size, the study may have been underpowered to detect meaningful differences. Fitts’ Law was observed for the lower extremity–pointing task for an LSS population and may provide an objective measure of motor performance.
