Advanced Practice – wohin?
Was ist zu diesem Thema bereits bekannt? Die psychiatrische Pflege ist im Umbruch und der Versorgungsbedarf wächst. Gleichzeitig ist auch die Psychiatrie vom Fachkräftemangel betroffen, weshalb neue Ansätze erforderlich sind. Wie wird eine neue Perspektive eingebracht? Mit der Rolle Psychiatric Mental Health Nurse Practitioner (PMHNP) wird ein im deutschsprachigen Raum neues Rollenprofil initiiert, welches Bestehendes aufnimmt und Neues schafft. Was sind die Auswirkungen für die Praxis? Mit der Implementierung von PMHNPs in der psychiatrischen Praxis wird die Pflege in interprofessionellen Teams an Profil gewinnen und sich weiterentwickeln.

Lung, Liver and Lymph Node Metastases in Follow-Up MSCT: Comprehensive Volumetric Assessment of Lesion Size Changes
Purpose: To investigate measurement accuracy in terms of precision and inter-rater variability in the simultaneous volumetric assessment of lung, liver and lymph node metastasis size change over time in comparison to RECIST 1.1. Materials and Methods: Three independent readers evaluated multislice CT data from clinical follow-up studies (chest/abdomen) in 50 patients with metastases. A total of 117 lung, 77 liver and 97 lymph node metastases were assessed manually (RECIST 1.1) and by volumetry with semi-automated software. The quality of segmentation and need for manual adjustments were recorded. Volumes were converted to effective diameters to allow comparison to RECIST. For statistical assessment of precision and interobserver agreement, the Wilcoxon-signed rank test and Bland-Altman plots were utilized. Results: The quality of segmentation after manual correction was acceptable to excellent in 95 % of lesions and manual corrections were applied in 21 – 36 % of all lesions, most predominantly in lymph nodes. Mean precision was 2.6 – 6.3 % (manual) with 0.2 – 1.5 % (effective) relative measurement deviation (p <.001). Inter-reader median variation coefficients ranged from 9.4 – 12.8 % (manual) and 2.9 – 8.2 % (volumetric) for different lesion types (p < .001). The limits of agreement were ± 9.8 to ± 11.2 % for volumetric assessment. Conclusion: Superior precision and inter-rater variability of volumetric over manual measurement of lesion change over time was demonstrated in a whole body setting. Ziel: Erforschung von Messgenauigkeit im Hinblick auf Präzision und Inter-Observer-Variabilität der gleichzeitigen volumetrischen Untersuchung der Größenänderung im Follow-up von Lungen-, Leber- und Lymphknotenmetastasen im Vergleich zu RECIST 1.1. Material und Methoden: 3 unabhängige Radiologen untersuchten Multislice-CT-Daten von 50 Patienten mit Metastasen aus klinischen Verlaufsuntersuchungen (Thorax/Abdomen). Insgesamt wurden 117 Lungen-, 77 Lebermetastasen und 97 Lymphknoten manuell (RECIST 1.1) und volumetrisch mit einer halbautomatischen Software vermessen. Die Qualität der Segmentation und der Einsatz manueller Nachverarbeitung wurden erfasst. Volumina wurden in Effektivdurchmesser umgewandelt, um sie direkt mit RECIST vergleichen zu können. Zur statistischen Analyse von Präzision und Inter-Observer-Variabilität wurden Wilcoxon-Vorzeichen-Rangtest und Bland-Altman Diagramme verwendet. Ergebnisse: Die Qualität der Segmentation nach manueller Korrektur wurde als akzeptabel bis hervorragend in 95 % bewertet, manuelle Korrekturen in 21 – 36 % aller Läsionen vorgenommen, am häufigsten an Lymphknoten. Mittlere Präzision war 2,3 – 6,3 % (manuell) und 0,2 – 1,5 % (Effektivdurchmesser) relative Messwert-Abweichung (p < 0,001). Mediane Inter-Observer-Variabilität lag im Bereich von 9,4 – 12,8 % (manuell) und 2,9 – 8,2 % (volumetrisch) in verschiedenen Läsionskategorien (p < 0,001). Limits of Agreement waren ± 9,8 bis ± 11,2 % in der volumetrischen Analyse. Schlussfolgerung: Volumetrische Messung der Größenänderungen im Follow-up zeigte eine signifikante Verbesserung von Präzision und Inter-Observer-Variabilität gegenüber manueller Messung im untersuchten Ganzkörperparadigma.

Transgenic insulin‐like growth factor‐1 stimulates activation of COX‐2 signaling in mammary glands
Studies show that elevated insulin‐like growth factor‐1 (IGF‐1) levels are associated with an increased risk of breast cancer; however, mechanisms through which IGF‐1 promotes mammary tumorigenesis in vivo have not been fully elucidated. To assess the possible involvement of COX‐2 signaling in the pro‐tumorigenic effects of IGF‐1 in mammary glands, we used the unique BK5.IGF‐1 mouse model in which transgenic (Tg) mice have significantly increased incidence of spontaneous and DMBA‐induced mammary cancer compared to wild type (WT) littermates. Studies revealed that COX‐2 expression was significantly increased in Tg mammary glands and tumors, compared to age‐matched WTs. Consistent with this, PGE2 levels were also increased in Tg mammary glands. Analysis of expression of the EP receptors that mediate the effects of PGE2 showed that among the four G‐protein‐coupled receptors, EP3 expression was elevated in Tg glands. Up‐regulation of the COX‐2/PGE2/EP3 pathway was accompanied by increased expression of VEGF and a striking enhancement of angiogenesis in IGF‐1 Tg mammary glands. Treatment with celecoxib, a selective COX‐2 inhibitor, caused a 45% reduction in mammary PGE2 levels, attenuated the influx of mast cells and reduced vascularization in Tg glands. These findings indicate that the COX‐2/PGE2/EP3 signaling pathway is involved in IGF‐1‐stimulated mammary tumorigenesis and that COX‐2‐selective inhibitors may be useful in the prevention or treatment of breast cancer associated with elevated IGF‐1 levels in humans.
