ABSTRACT
AIM: We investigated whether the Dementia Assessment Sheet for Community-based Integrated Care System-21 Items (DASC-21), a questionnaire that assesses cognitive function, including activities of daily living (ADL), was predictive of in-hospital death and prolonged hospital stay in elderly patients hospitalized for heart failure. METHODS: We retrospectively assessed the DASC-21 score at the time of admission, in-hospital death, length of hospital stay, and change in the Barthel index in 399 patients hospitalized for heart failure between 2016 and 2019. RESULTS: The mean patient age was 85.8 ± 7.7 years (61.3% women). The median DASC-21 score was 38 (64.7% higher than 31). On multivariate logistic regression analysis, a higher DASC-21 score was associated with an increased risk of in-hospital death (odds ratio [OR] = 1.045 per 1 point increase, 95% confidence interval [CI]: 1.010-1.081, P = 0.012), even after adjusting for confounding factors, including atrial fibrillation, ejection fraction, and B-type natriuretic peptide. Difficulties (3 or 4) with the self-management of medication in instrumental ADL inside the home (OR = 3.28, 95% CI: 1.05-10.28, P = 0.042), toileting (OR = 3.66, 95% CI: 1.19-11.29, P = 0.024), grooming (OR = 6.47, 95% CI: 2.00-20.96, P = 0.002), eating (OR = 7.96, 95% CI: 2.49-25.45, P < 0.001), and mobility in physical ADL (OR = 5.99, 95% CI: 1.85-19.35, P = 0.003) were identified as risk factors for in-hospital death. Patients in the highest tertile of the DASC-21 score had a significantly longer hospital stay (P = 0.006) and a greater reduction in the Barthel index (P < 0.001). CONCLUSIONS: In elderly patients hospitalized for heart failure, higher DASC-21 scores were associated with an increased risk of in-hospital death, prolonged hospital stay, and impaired ADL.

Left-dominant [Ca2+]i elevation on the left margin of the ventral node furnishes the initial laterality of mouse embryos. It depends on extracellular leftward fluid flow (nodal flow), fibroblast growth factor receptor (FGFR)/sonic hedgehog (Shh) signaling, and the PKD1L1 polycystin subunit, of which interrelationship is still elusive. Here, we show that leftward nodal flow directs PKD1L1-containing fibrous strands and facilitates Nodal-mediated [Ca2+]i elevation on the left margin. We generate KikGR-PKD1L1 knockin mice in order to monitor protein dynamics with a photoconvertible fluorescence protein tag. By imaging those embryos, we have identified fragile meshwork being gradually transferred leftward involving pleiomorphic extracellular events. A portion of the meshwork finally bridges over the left nodal crown cells in an FGFR/Shh-dependent manner. As PKD1L1 N-term is predominantly associated with Nodal on the left margin and that PKD1L1/PKD2 overexpression significantly augments cellular Nodal sensitivity, we propose that leftward transfer of polycystin-containing fibrous strands determines left-right asymmetry in developing embryos.
