Correlation of Formative Assessments as the Means of Predicting Summative Performance in Paramedic Students

Background: Paramedic programs use formative assessments to determine cognitive competency. Understanding the number of failed units as a probability of passing the summative exam will allow programs to set additional benchmarks. The purpose of this study was to determine whether failure in formative exams determines success on a summative exam. Methods: Formative and summative scores from 2011 - 2016 for paramedic students with accounts in Fisdap, an Internet-based administrative database, were retrospectively reviewed for the following criteria: provided consent for research, completed all six formative (unit) examinations, and completed a summative (comprehensive) examination. Analyses were performed with Pearson correlations and linear regression. Results: A total of 1,406 student records were included based on inclusion criteria. Correlation with each formative and the summative examination were all significant, p \u3c0.001: Cardiology 0.597; Airway 0.571; Medical 0.571; Trauma 0.566; Ob/Pediatrics 0.549; Operations 0.495. The cardiology exam was shown to have a moderate correlation on summative performance, whereas the operations exam had the weakest correlation. The number of formative examination failures was a significant predictor of the probability of passing the summative examination, t(1405) - -31.02 p\u3c0.001. Zero failed unit examinations yielded a 100% probability of passing. Three failed formative exams yielded a 60.4% probability. Four failed attempts yielded a 44.8% probability. Failure of all six formative exams yielded a 13.4% probability of passing the Paramedic Readiness Exam Version 3. Conclusion: Not all formative examinations hold the same predictive power on the probability of passing a summative examination. Each had their own correlation value. Students who did not fail formative examinations have a 100% likelihood of passing the summative examination

Phosphorylation of Mouse Immunity-Related GTPase (IRG) Resistance Proteins Is an Evasion Strategy for Virulent Toxoplasma gondii

GTPases of the mouse IRG protein family, mediators of resistance against Toxoplasma gondii in the mouse, are inactivated by a polymorphic kinase of the parasite, resulting in enhanced parasite virulence

Comparative Genomics of the Apicomplexan Parasites Toxoplasma gondii and Neospora caninum: Coccidia Differing in Host Range and Transmission Strategy

Toxoplasma gondii is a zoonotic protozoan parasite which infects nearly one third of the human population and is found in an extraordinary range of vertebrate hosts. Its epidemiology depends heavily on horizontal transmission, especially between rodents and its definitive host, the cat. Neospora caninum is a recently discovered close relative of Toxoplasma, whose definitive host is the dog. Both species are tissue-dwelling Coccidia and members of the phylum Apicomplexa; they share many common features, but Neospora neither infects humans nor shares the same wide host range as Toxoplasma, rather it shows a striking preference for highly efficient vertical transmission in cattle. These species therefore provide a remarkable opportunity to investigate mechanisms of host restriction, transmission strategies, virulence and zoonotic potential. We sequenced the genome of N. caninum and transcriptomes of the invasive stage of both species, undertaking an extensive comparative genomics and transcriptomics analysis. We estimate that these organisms diverged from their common ancestor around 28 million years ago and find that both genomes and gene expression are remarkably conserved. However, in N. caninum we identified an unexpected expansion of surface antigen gene families and the divergence of secreted virulence factors, including rhoptry kinases. Specifically we show that the rhoptry kinase ROP18 is pseudogenised in N. caninum and that, as a possible consequence, Neospora is unable to phosphorylate host immunity-related GTPases, as Toxoplasma does. This defense strategy is thought to be key to virulence in Toxoplasma. We conclude that the ecological niches occupied by these species are influenced by a relatively small number of gene products which operate at the host-parasite interface and that the dominance of vertical transmission in N. caninum may be associated with the evolution of reduced virulence in this species
