BACKGROUND: The COVID-19 pandemic presents a unique challenge to surgical residency programs. Due to the restrictions recommended by the Centers for Disease Control and Prevention and other organizations, the educational landscape for surgical residents is rapidly changing. In addition, the time course of these changes is undefined. METHODS: We attempt to define the scope of the problem of maintaining surgical resident education while maintaining the safety of residents, educators, and patients. Within the basic framework of limiting in-person gatherings, postponing or canceling elective operations in hospitals, and limiting rotations between sites, we propose innovative solutions to maintain rigorous education. RESULTS: We propose several innovative solutions including the flipped classroom model, online practice questions, teleconferencing in place of in-person lectures, involving residents in telemedicine clinics, procedural simulation, and the facilitated use of surgical videos. Although there is no substitute for hands-on learning through operative experience and direct patient care, these may be ways to mitigate the loss of learning exposure during this time. CONCLUSIONS: These innovative solutions utilizing technology may help to bridge the educational gap for surgical residents during this unprecedented circumstance. The support of national organizations may be beneficial in maintaining rigorous surgical education.

Purpose AE37 and GP2 are HER2 derived peptide vaccines. AE37 primarily elicits a CD4+ response while GP2 elicits a CD8+ response against the HER2 antigen. These peptides were tested in a large randomized trial to assess their ability to prevent recurrence in HER2 expressing breast cancer patients. The primary analyses found no difference in 5-year overall disease-free survival (DFS) but possible benefit in subgroups. Here, we present the final landmark analysis. Methods In this 4-arm, prospective, randomized, single-blinded, multi-center phase II trial, disease-free node positive and high-risk node negative breast cancer patients enrolled after standard of care therapy. Six monthly inoculations of vaccine (VG) vs. control (CG) were given as the primary vaccine series with 4 boosters at 6-month intervals. Demographic, safety, immunologic, and DFS data were evaluated. Results 456 patients were enrolled; 154 patients in the VG and 147 in CG for AE37, 89 patients in the VG and 91 in CG for GP2. The AE37 arm had no difference in DFS as compared to CG, but pre-specified exploratory subgroup analyses showed a trend towards benefit in advanced stage (p = 0.132, HR 0.573 CI 0.275-1.193), HER2 under-expression (p = 0.181, HR 0.756 CI 0.499-1.145), and triple-negative breast cancer (p = 0.266, HR 0.443 CI 0.114-1.717). In patients with both HER2 under-expression and advanced stage, there was significant benefit in the VG (p = 0.039, HR 0.375 CI 0.142-0.988) as compared to CG. The GP2 arm had no significant difference in DFS as compared to CG, but on subgroup analysis, HER2 positive patients had no recurrences with a trend toward improved DFS (p = 0.052) in VG as compared to CG. Conclusions This phase II trial reveals that AE37 and GP2 are safe and possibly associated with improved clinical outcomes of DFS in certain subgroups of breast cancer patients. With these findings, further evaluations are warranted of AE37 and GP2 vaccines given in combination and/or separately for specific subsets of breast cancer patients based on their disease biology.Keywords Immunotherapy · Vaccine · Breast cancer · HER2 · AE37 · GP2 Abbreviations CGControl group CI 95% Confidence interval CTLCytotoxic T-lymphocyte DFS Disease-free survival GM-CSF Granulocyte-macrophage colony-stimulating factor

Transport of critically ill intensive care unit (ICU) patients may be hazardous. In this study, we examined the use of a portable head CT scanner (CereTom A ) in the ICU to assess its feasibility, safety, and radiological quality. Two hundred and twenty-five portable head CT scans were obtained from 114 patients (mean age = 57 T 18 years) treated in a neurosurgical intensive care unit at a university-based Level I trauma center. Patient radiological and ICU records were retrospectively reviewed. The vast majority of portable CT scans were performed after an intracranial procedure (24%) due to neurological deterioration (16%) or in routine follow-up (16%). Diagnostic quality was judged to be adequate, and no scans needed to be repeated because of poor quality. No scans were complicated by accidental disconnection of an intravenous line. In ventilated patients, there were no interruptions in mechanical ventilation and no inadvertent extubations. In addition, continuous intracranial monitoring, when in use, remained connected. The average total time to perform a portable head CT scan was 19.5 T 3.5 min. The actual scan time was 2.5 T 0.7 min. These results suggest that the portable CT scanner (CereTom A ) is feasible, easy to use, and safe and provides adequate radiological quality for diagnostic decisions.
