Distribution of planktonic foraminifera in Oligocene-Miocene of three drill sites from the netherlands Peel area

Es ist Ihnen wohl bekaililt, daß bei der Feingliederung des Tertiärs im Tethysraum immer mehr die planktonischen Foraminiferen berücksichtigt werden. Diese Fossilien hatten durch ihre Lebensweise die Möglichkeit einer großen horizontalen Verbreitung und sind deswegen für die Stratigraphie besonders wichtig. Sehr weit ist die Feingliederung des Oligo-Miocän zum Beispiel fortgeschritten in Trinidad, wo neuerdings BOLLI (1957) ein sehr detailliertes Schema aufgestellt hat. Man muß aber für eine allgemeine Verwendung einer solchen Einteilung noch sehr vorsichtig sein

The impact of endoxifen-guided tamoxifen dose reductions on endocrine side-effects in patients with primary breast cancer

BACKGROUND: Tamoxifen is important in the adjuvant treatment of hormone-sensitive breast cancer and substantially reduces recurrence; however, almost 50% of patients are non-compliant mainly due to side-effects. The aim of this study was to investigate whether endoxifen-guided tamoxifen dose reduction could lead to fewer side-effects. MATERIALS AND METHODS: Effects of tamoxifen dose reduction were investigated in patients with bothersome side-effects and endoxifen levels ≥32 nM and compared to patients with side-effects who remained on tamoxifen 20 mg. Endocrine symptoms and health-related quality of life (HR-QOL) were assessed after 3 months with the Functional Assessment of Cancer Therapy-Endocrine Symptoms (FACT-ES) questionnaire. RESULTS: Tamoxifen dose was reduced in 20 patients, 17 of whom were assessable for side-effect analyses. A clinically relevant improvement of >6 points was observed in endocrine symptoms and HR-QOL in 41% and 65% of the patients, respectively. In total, there was a significant and clinically relevant improvement in endocrine symptoms [5.7, 95% confidence interval (CI) -0.5-11.5] and HR-QOL (8.2, 95% CI 0.9-15.4) after dose reduction. This was not seen in patients whose doses were not reduced (n = 60). In 21% of patients, endoxifen dropped slightly below the 16-nM threshold (12.8, 15.5, 15.8, 15.9 nM). CONCLUSIONS: Endoxifen-guided dose reduction of tamoxifen significantly improved tamoxifen-related side-effects and HR-QOL. Nearly 80% of patients remained above the most conservative endoxifen threshold

Possible alleviation of symptoms and side effects through clinicians' nocebo information and empathy in an experimental video vignette study

To alleviate anti-cancer treatment burden in advanced breast cancer, patient-clinician communication strategies based on nocebo-effect mechanisms are promising. We assessed distinct/combined effects on psychological outcomes (e.g. anxiety; main outcome) and side-effect expectations of (1) nocebo information about the (non)pharmacological origin of side effects, and (2) clinician-expressed empathy through reassurance of continuing support. Furthermore, we explored whether information and empathy effects on side-effect expectations were mediated by decreased anxiety. In a two-by-two experimental video-vignette design, 160 cancer patients/survivors and healthy women watched one of four videos differing in level of nocebo information (±) and empathy (±). Regression and mediation analysis were used to determine effects of information/empathy and explore anxiety's mediating role. Anxiety was not influenced by empathy or information (Stai-state: p = 0.295; p = 0.390, VAS p = 0.399; p = 0.823). Information improved (specific) side-effect coping expectations (p < 0.01). Empathy improved side-effect intensity expectations (p < 0.01 = specific; p < 0.05 = non-specific/partial) and specific side-effect probability expectations (p < 0.01), and increased satisfaction, trust, and self-efficacy (p < 0.001). No mediating effects were found of anxiety on expectations. Mainly empathy, but also nocebo information improved psychological outcomes and-mainly specific-side-effect expectations. Exploring the power of these communication elements in clinical practice is essential to diminish the anti-cancer treatment burden in advanced breast cancer.Applied Ergonomics and DesignHR Healt
