We expand the application of cost frontiers and introduce a novel approach using qualitative multivariable financial analyses. ⋯ In summary, we demonstrate that multivariable cost (or performance) frontiers can track a net increase in profitability associated with fellowship implementation despite diminishing returns at higher caseloads.

This study aimed to compare the postoperative and pathological outcomes between carboplatin, paclitaxel, radiotherapy (CROSS) and 5-FU, leucovorine, oxaliplatin and docetaxel (FLOT) in esophageal adenocarcinoma (EAC) patients from an international, multicenter cohort. ⋯ This study provides real-world data CROSS was associated with higher 90-day mortality than FLOT, related to cardio-pulmonary complications with CROSS. These warrant a further review into causes and mechanisms in selected patients, and at minimum suggest the need for strict radiation therapy quality assurance. Research into impact of higher pCR rates and R0 resections with CROSS compared to FLOT on long-term survival is needed.

The aim of this study was to determine overall trends and center-level variation in utilization of completion lymph node dissection (CLND) and adjuvant systemic therapy for sentinel lymph node (SLN)-positive melanoma. ⋯ There has been an overall decline in CLND and simultaneous adoption of adjuvant systemic therapy for patients with SLN-positive melanoma though wide variation in practice remains. Accounting for differences in patient mix, location of care contributed significantly to the observed variation.

Randomized Controlled Trial
Adenosine causes short-lasting vasodilation and headache, but not migraine attacks in migraine patients: A randomized clinical trial.
Migraine is a common disabling disease with a complex pathophysiology. Headache is a frequent side effect after intravenous adenosine administration, although adenosine receptor antagonist, caffeine, relieves migraine headache. These observations suggest a possible involvement of adenosine signaling in headache and migraine pathophysiology. ⋯ Adenosine increased heart rate ( P < 0.001), facial skin blood flow ( P < 0.05), and STA diameter (AUC T0-20min , P = 0.01) and decreased V MCA (AUC T0-20min , P < 0.001) compared with placebo. Adenosine induced headache accompanied by a short-lasting (<30 minutes) dilation of intracerebral and extracerebral arteries. The nonsignificant migraine induction might be because of the presence of several adenosine receptors with counteracting signaling, highlighting the need of more selective modulators to dissect the implication of adenosine in migraine.
