ABSTRACT
Bevacizumab (BEV, Avastin(®)) produces durable objective radiological responses of 20-26 %, median response durations of 16-18 weeks, and median overall survival (mOS) of 31-40 weeks. While the use of BEV is well-established, the lack of dose-response studies in glioblastoma (GBM) patients raises the question whether current dosing practice is optimal. As a result of differing approaches to BEV dosing that ranged from the FDA approved package insert dose of 10 mg/kg every 2 weeks to 7.5 mg/kg every 3-4 weeks, among physicians within Northern California Kaiser Permanente hospitals over 4+ years, we did an IRB-approved retrospective analysis of patients seen in Northern California Kaiser Permanente facilities and treated with BEV. Between September 1, 2008 and August 31, 2013, 181 patients received BEV for tumor progression/recurrence starting 2.6 weeks after completion of chemoradiation. The integrated BEV administered dose-week (AUCBEV) for all patients had a median AUCBEV of 3.6 mg·wk/kg). Maximum likelihood analysis found patients over 65 years did worse than younger patients (p = 0.004), women lived longer (p = 0.002), and patients treated below the AUCBEV did better than those treated above the median AUCBEV (p = 0.003). mOS for BEV starting 1 month after chemoradiation was 45 versus 68 weeks (p = 0.012) and BEV starting 3 months after chemoradiation was 40 versus 74 weeks (p = 0.0085). Dosing BEV at half the standard dose for progressive/recurrent GBM was at least equivalent to or, maybe better than standard dosing. Unexplained was the observation that females had longer OS with BEV than males.

OBJECTIVES: The purpose of this study was to investigate the relationship between personality traits (perfectionism and neuroticism) and the traumatic outcomes of reexperiencing, avoidance, and alcohol abuse severity of registered nurses (RNs) who have been involved with a patient safety incident (PSI). We hypothesized that higher scores for perfectionism and neuroticism would predict higher reexperiencing and avoidance symptoms in RNs in the aftermath of a PSI. Also, RNs with higher perfectionism and neuroticism sum scores would be more likely to abuse alcohol. METHODS: A descriptive, correlational study design was used to characterize the relationships of personality traits and potential traumatic outcomes of RNs in the aftermath of a PSI. The Almost Perfect Scale-Revised, Neuroticism Scale, Posttraumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders, and Alcohol Use Disorders Identification Test-Consumption measures were administered to RNs licensed in Oregon and New York. RESULTS: Perfectionist-discrepancy personality traits (P < 0.01) were the strongest predictors for reexperiencing symptoms and neuroticism (P < 0.05) was the strongest predictor for avoidance symptoms, when controlling for sociodemographics and experience. We found a negative linear relationship between perfectionism-order and alcohol abuse severity (ß = -0.15, P < 0.01; confidence interval, -0.24 to 0.05). CONCLUSIONS: This study demonstrated a statistically significant relationship between perfectionism-discrepancy and reexperiencing as well as between neuroticism and reexperiencing and avoidance, each explaining 4% of variance of their model. The results add to the nurse second victim literature by validating 2 posttraumatic stress disorder symptoms in RNs in the aftermath of a PSI. Registered nurses with perfectionism-order were less likely to abuse alcohol.
