Impact of Massive Transfusion Activation on Time to Delivery of the First Cooler and Patient Survival: A Study of 4,313 Consecutive Activations.

Background: In 2012, TQIP guidelines for massive transfusion protocols (MTP) recommended delivery of blood product coolers within 15 minutes. Subsequent work found that every minute delay in cooler arrival was associated with a 5% increased risk of mortality. We sought to assess the impact and sustainability of quality improvement (QI) interventions on time to MTP cooler delivery and their association with trauma patient survival.

Non-native species have higher consumption rates than their native counterparts.

Non-native species can be major drivers of ecosystem alteration, especially through changes in trophic interactions. Successful non-native species have been predicted to have greater resource use efficiency relative to trophically analogous native species (the Resource Consumption Hypothesis), but rigorous evidence remains equivocal. Here, we tested this proposition quantitatively in a global meta-analysis of comparative functional response studies.

Characterization of an Aortic Valve Papillary Fibroelastoma Using Three-Dimensional Transillumination Echocardiography.

• PFEs are a cause of cardioembolic events. • TI represents a newer photorealistic rendering of 3D echo. • TI may assist in the identification of intracardiac masses, including PFEs.

The relationship between prognostic factors and patient satisfaction with performance of self-identified goals following interdisciplinary mild traumatic brain injury rehabilitation.

Background: Individuals with persistent symptoms following a mild traumatic brain injury (mTBI) demonstrate improved satisfaction with their performance of self-identified rehabilitation goals after completing a combined occupational therapy and physiotherapy group intervention. However, the relationship between factors associated with developing persistent symptoms following an mTBI and satisfaction with their performance of self-identified goals after completing an intervention are unknown.

Objective(s): To evaluate whether factors associated with developing persistent symptoms influence satisfaction with the performance of self-identified goals after completing a combined occupational therapy and physiotherapy group intervention.

Test-retest reliability and longitudinal validity of drop vertical jump biomechanics during rehabilitation after ACL reconstruction.

Hip and knee biomechanics measured during a drop vertical jump (DVJ) can be used to assess patients undergoing rehabilitation after anterior cruciate ligament (ACL) reconstruction. To confidently interpret such data for use as outcome measures, additional information about reliability and validity is required. Therefore, the objective of this study was to estimate the test-retest reliability and longitudinal validity of selected lower limb biomechanics assessed during a DVJ in patients undergoing rehabilitation after ACL reconstruction.
