Palliative care on the radiation oncology ward-improvements in clinical care through interdisciplinary ward rounds.

INTRODUCTION: Palliative care is essential for patients with terminal diseases and aims at effective symptom control. This may stand in opposition to radiation treatment as an oncological treatment modality. The hereby presented work demonstrates the successful integration of a palliative care service in the radiation oncology ward. METHODS: Since 2015, 1018 patients were seen by the palliative care service on the radiation oncology ward and have been analyzed in this single center study. To assess teaching efficacy of the consultation service, a survey was conducted among 15 radiation oncology residents. RESULTS: Cooperation between the two departments proved to be efficient with rising patient numbers. Palliative care was able to guide appropriate postdischarge care with the number of patients dying on the radiation oncology ward decreasing significantly (p = 0.009). The main topics for consultation were pain medication (92.3%), organization of postdischarge care (92.3%), and psycho-oncological support (84.6%). Most residents had a positive image of the palliative care service and consented on adjectives like "enriching", "empathic", "collegial", "professionally founded", and a "low threshold for consultation". All participants agreed that cooperation deepened their knowledge on palliative care. CONCLUSION: A synergistic cooperation between a palliative care consultation service and a radiation oncology department addresses patient symptoms on an individual level. It confers advanced knowledge on palliative care which is essential for resident education and patient treatment.

Digital Holographic Microscopy for Label-Free Detection of Leukocyte Alternations Associated with Perioperative Inflammation after Cardiac Surgery.

In a prospective observational pilot study on patients undergoing elective cardiac surgery with cardiopulmonary bypass, we evaluated label-free quantitative phase imaging (QPI) with digital holographic microscopy (DHM) to describe perioperative inflammation by changes in biophysical cell properties of lymphocytes and monocytes. Blood samples from 25 patients were investigated prior to cardiac surgery and postoperatively at day 1, 3 and 6. Biophysical and morphological cell parameters accessible with DHM, such as cell volume, refractive index, dry mass, and cell shape related form factor, were acquired and compared to common flow cytometric blood cell markers of inflammation and selected routine laboratory parameters. In all examined patients, cardiac surgery induced an acute inflammatory response as indicated by changes in routine laboratory parameters and flow cytometric cell markers. DHM results were associated with routine laboratory and flow cytometric data and correlated with complications in the postoperative course. In a subgroup analysis, patients were classified according to the inflammation related C-reactive protein (CRP) level, treatment with epinephrine and the occurrence of postoperative complications. Patients with regular courses, without epinephrine treatment and with low CRP values showed a postoperative lymphocyte volume increase. In contrast, the group of patients with increased CRP levels indicated an even further enlarged lymphocyte volume, while for the groups of epinephrine treated patients and patients with complicative courses, no postoperative lymphocyte volume changes were detected. In summary, the study demonstrates the capability of DHM to describe biophysical cell parameters of perioperative lymphocytes and monocytes changes in cardiac surgery patients. The pattern of correlations between biophysical DHM data and laboratory parameters, flow cytometric cell markers, and the postoperative course exemplify DHM as a promising diagnostic tool for a characterization of inflammatory processes and course of disease.
