RESUMEN
The study subjects consisted of 54 patients with inoperable or recurrent breast cancer who were administered a combination of palbociclib plus endocrine therapy. We examined the onset of neutropenia during the first course of treatment and evaluated the influence that various risk factors had on treatment continuity. Patients with neutropenia Grade≥3 had significantly lower relative dose intensity(RDI) values during the first course of treatment than did patients with neutropenia Grade ≤2. Patients with neutropenia Grade≥3 showed significantly longer treatment to failure than did patients with neutropenia Grade≤2. These results suggest that the degree of neutropenia during the first course of treatment might contribute to treatment continuity and that it is important to improve the curative effect by maintaining appropriate RDI and by continuously administering palbociclib in patients with neutropenia Grade≥3.

AIMS: There have been some reports about the efficacy of trauma team activation. In November 2015, we implemented a trauma call system, wherein a general surgeon, neurosurgeon, and orthopedic surgeon are called to the emergency department when severe trauma patients are transferred to our emergency department. In this study, we evaluated the efficacy of this trauma call system. METHODS: The purpose of the present study was to evaluate the efficacy of a trauma call system for trauma cases with an Injury Severity Score ≥16. We compared the mortality of trauma cases and the time from arrival to the start of the examination and intervention before and after implementing this trauma call system. RESULTS: There was no significant difference in the mortality rates before and after the implementation of the trauma call system. The median time from arrival to the start of contrast-enhanced computed tomography or transcatheter arterial embolization improved from 54 to 19 min (P = 0.015) and 171 to 84 min (P = 0.030), respectively, after the implementation of the trauma call system. CONCLUSION: Our trauma call system did not significantly improve the mortality of trauma patients with an Injury Severity Score ≥16. However, it was effective for reducing the time from the arrival to the start of contrast-enhanced computed tomography or transcatheter arterial embolization.
