[Requirements for outpatient care after implantation of a ventricular assist device : Views of patients and their relatives]. / Anforderungen an die ambulante Versorgung nach Implantation eines ventrikulären Herzunterstützungssystems : Sichtweise von Patienten und Angehörigen.

Ventricular assist device (VAD) implantation has developed into a well-established option when conservative treatment of terminal heart failure has been exhausted. Figures from 2015 make this clear: only 283 heart transplantations were performed nationwide but 959 VAD systems were implanted. It is noteworthy that the survival times with a VAD are approaching the survival times after heart transplantation. Patients with VADs have a life-long dependency on their proximity to specialists. So far, the requirements for outpatient care have not been systematically recorded from the perspective of VAD patients and their relatives. In September 2016, VAD patients (n = 30) and their relatives (n = 25) were anonymously questioned about their views on postoperative outpatient care. For this purpose, the VAD Patient Satisfaction Survey was adapted to the needs of this study. Patients with VADs and their relatives were found to experience their daily life with a VAD in a positive manner. Information, training, accessibility and regular contacts with the implantation clinic and the VAD coordinator are important pillars of outpatient care after VAD implantation. Almost 95% of surveyed patients regarded good home support as an important factor that makes life with a VAD easier. These aspects should be taken into account in the care of patients living with a VAD.

Inflammatory response in transapical transaortic valve replacement.

OBJECTIVE: Transapical aortic valve implantation (TA-AVI) has become a fast growing alternative to conventional aortic valve replacement (cAVR) particularly for patients burdened with serious comorbidities. We investigated whether the inflammatory response triggered by TA-AVI reflects the less invasive nature of this procedure. METHOD: In this prospective observational study 25 patients undergoing aortic valve replacement (AVR; 15 cAVR and 10 TA-AVI) were included. Serial plasma cytokine concentrations (IL-6, IL-8, and IL-10) were measured by commercially available enzyme-linked immunosorbent assay kits at six different time points before, during, and after surgery. RESULTS: Plasma levels of all three cytokines increased during and after both procedures and returned to baseline before the patient's discharge. Peak values of IL-6 were 258 ± 113 pg/mL in AVR patients versus 111 ± 101 pg/mL in TA-AVI patients and were reached 12 hours after surgery. For IL-8, peak values were 51 ± 29 pg/mL 1 hour after surgery in AVR patients versus 15 ± 20 pg/mL on wound closure in TA-AVI patients. Plasma levels of IL-6 and IL-8 were significantly reduced in the TA-AVI group as compared with cAVR. IL-10 is markedly activated in both groups yet its induction is more prominent in AVR patients with peak values of 51 ± 28 pg/mL for AVR versus 24 ± 18 pg/mL for TA-AVI on wound closure. CONCLUSION: TA-AVI compared with cAVR results in a significant reduction but not elimination of a systemic inflammatory response, which is attributable to cardiopulmonary bypass-dependent and bypass-independent factors.

Screen-detected breast cancers have a lower mitotic activity index.

We know that screening for breast cancer leads to detection of smaller tumours with less lymph node metastases. Could it be possible that the decrease in mortality after screening is not only caused by this earlier stage, but also by a different mitotic activity index (MAI) of the tumours that are detected by screening? Is MAI a prognostic factor for recurrence-free survival? A retrospective study was carried out of 387 patients with breast cancer, treated at the University Hospital Nijmegen between January 1992 and September 1997. Ninety patients had screen-detected breast cancer, 297 patients had breast cancers detected outside the screening programme. The MAI, other prognostic factors and recurrence-free survival were determined. In non-screen-detected tumours the MAI is twice as high as in screen-detected tumours, even after correction for age took place. The MAI correlated well with other tumour characteristics. The MAI in itself is a prognostic factor for recurrence-free survival. Favourable outcome in screen detected breast cancer is not entirely caused by detecting cancer in early stages: quantitative features such as the MAI indicate a less malignant character of screen detected breast cancer. The MAI is an independent prognostic factor for recurrence-free survival.
