The aim of this study was to demonstrate feasibility of migration and in situ chemotherapy delivery to regional lymph nodes (LN) in a large animal model using an expansile polymer nanoparticle (eNP) delivery system. ⋯ Regionally-targeted intranodal chemotherapy can be delivered to draining LNs for both skin and solid organs using 50-nm paclitaxel-loaded eNP.

Review Meta Analysis
A systematic review and meta-analysis of diagnostic screening criteria for blunt cerebrovascular injuries.
Despite progress in diagnosing and managing blunt cerebrovascular injury (BCVI), controversy remains regarding the appropriate population to screen. A systematic review of published literature was conducted to summarize the overall incidence of BCVI and the various screening criteria used to detect BCVI. A meta-analysis was performed to evaluate which screening criteria may be associated with BCVI. Goals were to confirm inclusion of certain criteria in current screening protocols and possibly eliminate criteria not associated with BCVI. ⋯ Patients with cervical spine and thoracic injuries had significantly greater likelihoods of BCVI compared with patients without these injuries. All patients with either injury should be screened for BCVI. Multivariate logistic regression analysis is needed to elucidate the possible impact of the combined presence of screening criteria, but it was not possible in our study due to limitations in data presentation. Standardized reporting of BCVI data is not established and is recommended to permit future collaboration.

Multicenter Study
An online spaced-education game to teach and assess residents: a multi-institutional prospective trial.
While games are frequently used in resident education, there is little evidence supporting their efficacy. We investigated whether a spaced-education (SE) game can be both a reliable and valid method of assessing residents' knowledge and an effective means of teaching core content. ⋯ An SE game is a reliable and valid means to assess residents' knowledge and is a well-accepted method by which residents can master core content.

Clinical management of papillary breast lesions (PBLs) remains controversial. The objective of this study was to identify pathologic and radiologic predictors of malignancy from a large cohort of PBLs diagnosed on core-needle biopsy (CNB). ⋯ Frequent upgrade to a high-risk lesion or cancer is observed with IDPs diagnosed on CNB without adequate identifiable clinical and radiographic risk factors. Surgical excision should be performed for all IDPs to delineate subsequent clinical management.
