Background:Heart failure (HF) and cancer (CA) are becoming increasingly prevalent as the population ages. We aimed to evaluate prior history and occurrence of CA and its prognostic impact on HF.Methods and Results:Consecutive hospitalized HF patients (n=2,103) were divided into 2 groups according to prior history of CA: non-prior-CA group (n=1,828) and prior-CA group (n=275). Compared with the non-prior-CA group, the prior-CA group were older, and had higher prevalence of chronic kidney disease, anemia, and atrial fibrillation (P<0.05). In contrast, sex, other comorbidities, levels of natriuretic peptide and ejection fraction were comparable between groups. We focused on newly diagnosed CA after discharge for HF. In the follow-up period (median 623 days), 114 (6.2%) patients in the non-prior-CA and 17 (6.2%) patients in the prior-CA groups were newly diagnosed as having CA. Additionally, 83 (3.9%) CA-related patient deaths occurred (median 776 days). In the Kaplan-Meier analysis (median 1,037 days), not only all-cause death but also cardiac event rate was significantly higher in the prior-CA group than in the non-prior-CA group (log-rank P<0.01). In the Cox proportional hazard analysis, CA history was a predictor of cardiac event rate (HR 1.450, 95% CI 1.134–1.822), as well as all-cause death (HR 2.483, 95% CI 2.034–3.030).Conclusions:Prior-CA history was associated with high cardiac event and mortality rates. CA is notable comorbidity in HF patients.

Communication between screens and cameras has attracted attention as a ubiquitous information source, motivated by the widespread use of smartphones and the increase of public information screens. The method that encodes data into visible patterns impairs the user's visual experience. Previously, embedding matrix barcodes into images on displays by utilizing imperceptible color vibration was proposed. In this approach, the visual experience is maintained considering that barcodes are imperceptible, and it can be implemented on almost any display and camera. Herein, we describe a sophisticated modulation protocol and restoration procedure whereby device characteristics such as the display's gamma feature and the smartphone's rolling shutter are taken into consideration. Extensive experiments reveal the parameters for the modulation and that this system works under practical situations. In addition, scenarios of potential practical applications and a user study examining imperceptibility of barcodes and usability of the system are presented to illustrate the technological capabilities.
