Anatomy knowledge has been found to include both spatial and non-spatial components. However, no systematic evaluation of studies relating spatial abilities and anatomy knowledge has been undertaken. The objective of this study was to conduct a systematic review of the relationship between spatial abilities test and anatomy knowledge assessment. A literature search was done up to March 20, 2014 in Scopus and in several databases on the OvidSP and EBSCOhost platforms. Of the 556 citations obtained, 38 articles were identified and fully reviewed yielding 21 eligible articles and their quality were formally assessed. Non-significant relationships were found between spatial abilities test and anatomy knowledge assessment using essays and non-spatial multiple-choice questions. Significant relationships were observed between spatial abilities test and anatomy knowledge assessment using practical examination, three-dimensional synthesis from two-dimensional views, drawing of views, and cross-sections. Relationships between spatial abilities test and anatomy knowledge assessment using spatial multiple-choice questions were unclear. The results of this systematic review provide evidence for spatial and non-spatial methods of anatomy knowledge assessment. Anat Sci Educ 10: 235-241. © 2016 American Association of Anatomists.

Spatial abilities have been correlated to anatomy knowledge assessment and spatial training has been found to improve spatial abilities in previous systematic reviews. The objective of this systematic review was to evaluate spatial abilities training in anatomy education. A literature search was done from inception to 3 August 2017 in Scopus® and several databases on the EBSCOhost platform. Citations were reviewed and those involving anatomy education, an intervention, and a spatial abilities test were retained and the corresponding full‐text articles were reviewed for inclusion. Before and after training studies, as well as comparative training programs, relating a spatial training intervention to spatial abilities were eligible. Of the 2,405 citations obtained, 52 articles were identified and reviewed, yielding eight eligible articles. Instruction in anatomy and mental rotations training were found to improve spatial abilities. For the seven studies retained for the meta‐analysis that included the effect of interventions on spatial abilities test scores, the pooled treatment effect difference was 0.49 (95% CI [0.17; 0.82]; n = 11) improvement. For the two studies that included the practice effect on spatial abilities test scores in a control group, the pooled treatment effect difference was 0.47 (95% CI [−0.03; 0.97]; n = 2) improvement. In these two studies, the impact of the intervention on spatial abilities test scores was found despite the practice effect. Evidence was found for improvement of spatial abilities in anatomy education using instruction in anatomy and mental rotations training.

To determine the cytokine release during normothermic cardiopulmonary bypass, we have measured plasmatic levels of tumor necrosis factor-a and interleukins-l,B, 6, and 8 in 10 patients during the first 24 hours after the start of bypass. Arterial blood samples were coUected at intervals before, during, and after bypass. Interleukin-l,B was not detectable in the plasma, .and traces of tumor necrosis factor-a were detected in only three patients at times independent of the cardiopulmonary bypass procedure. Circulating endotoxin remained undetectable. Plasma interleukin-6 and interleukin-8 rose significantly from 2 until 24 hours after the start of bypass (p < 0.05) and peaked respectively at 4 and 2 hours after the beginning of bypass (interleukin-6, 268.1 ± 131.43 pg/m1; interleukin-8, 370 ± 420 pg/m1; mean peak ± standard deviation). Peak values of interleukin-6 and interleukin-8 were correlated neither with the duration of aortic crossclamping or the bypass procedure nor with the hemodynamic parameters recorded at the same times. This study shows that normothermic cardiopulmonary bypass does not induce systemic release of tumor necrosis factor-a and interleukin-l,B. A local production of these cytokines cannot be excluded, because interleukin-6 and interleukin-8 are produced by stimulated macrophages and monocytes in response to tumor necrosis factor-a and interleukin-l,B. Our results, at normothermia, show a similar pattern of interleukin-6 and interleukin-8 release when compared with release during hypothermic cardiopulmonary bypass. Interleukin-8, an important chemotactic neutrophil factor, might playa role in reperfusion injuries observed in lungs and heart after cardiopulmonary bypass.
