The aim of this study is to clarify the outcomes of blood culture tests in patients with advanced cancer receiving hospice care. A total of 527 patients who took blood culture tests between April 2021 and March 2024 at our palliative care unit were included in the study. The rate of multiple blood culture set collection, positivity rate and contamination rate were 73.4%, 22.5% and 2.6%, respectively. The most-frequently-isolated pathogen was coagulase-negative staphylococci (28.8%). The rate for antimicrobial-resistant bacteria was 4.5%. Among the positive patients, 79.2% were administered appropriate antimicrobial regimens based on the drug susceptibility tests. The most frequently used antimicrobial as targeted therapy for bacteremia was vancomycin (31.5%). Despite their short lifespans, we conclude that blood culture test can be beneficial for patients receiving palliative care. Further observational studies are required to clarify characteristics of infectious diseases in terminally-ill patients with advanced cancer.

OBJECTIVE: To selectively visualize the left gastric vein (LGV) with hepatopetal flow information by non-contrast-enhanced magnetic resonance angiography under a hypothesis that change in the LGV flow direction can predict the development of esophageal varices; and to optimize the acquisition protocol in healthy subjects. MATERIALS AND METHODS: Respiratory-gated three-dimensional balanced steady-state free-precession scans were conducted on 31 healthy subjects using two methods (A and B) for visualizing the LGV with hepatopetal flow. In method A, two time-spatial labeling inversion pulses (Time-SLIP) were placed on the whole abdomen and the area from the gastric fornix to the upper body, excluding the LGV area. In method B, nonselective inversion recovery pulse was used and one Time-SLIP was placed on the esophagogastric junction. The detectability and consistency of LGV were evaluated using the two methods and ultrasonography (US). RESULTS: Left gastric veins by method A, B, and US were detected in 30 (97%), 24 (77%), and 23 (74%) subjects, respectively. LGV flow by US was hepatopetal in 22 subjects and stagnant in one subject. All hepatopetal LGVs by US coincided with the visualized vessels in both methods. One subject with non-visualized LGV in method A showed stagnant LGV by US. CONCLUSION: Hepatopetal LGV could be selectively visualized by method A in healthy subjects.
