Abstract
Abstract
Background
Renal dysfunction is associated with poor mortality in patients with heart failure (HF). Hepatic dysfunction, assessed by Fibrosis-4 (FIB4) index, has also prediction ability in acute decompensated HF (ADHF) patients. We investigated whether the assessment of the combination of FIB4 index and renal dysfunction improves predictability in patients with ADHF.
Methods
We retrospectively enrolled consecutive 758 patients who admitted due to ADHF from January 2011 to February 2018 and followed up for one year. FIB4 index on admission was calculated by the formula: age (yrs) × AST[U/L] / (platelets [103/μL] × (ALT[U/L])1/2). Study subjects were divided into high FIB4 index (>3.25) and low FIB4 index (≤3.25), furthermore each group were classified by the presence/absence of CKD (estimated glomerular filtration rate <60 ml/min/1.73m). We have generated four groups; low FIB4/without CKD (n=154), low FIB4/with CKD (n=294), high FIB4/without CKD (n=56), and high FIB4/with CKD (n=254). The primary outcome was defined as all-cause mortality in one year. We performed Kaplan-Meyer analysis and multivariable Cox regression models. Furthermore, we evaluated the incremental value with C-index, net reclassification improvement (NRI) and integrated discrimination improvement (IDI) when FIB4 index and renal dysfunction added to a baseline model.
Results
In total, 106 patients died in one year. High FIB4 index and CKD showed significantly higher 1-year mortality (high FIB4 index: 19.7% vs 10.3%, p<0.001, CKD: 17.0% vs 6.7%, p<0.001, respectively). Kaplan-Meyer analysis shows that high FIB4 index with CKD showed statistically higher mortality than the others (vs low FIB4/without CKD, p<0.001, vs high FIB4/without CKD, p=0.031, vs low FIB4/with CKD, p<0.001, respectively).
Multivariate Cox regression model revealed that both high FIB4 index and CKD were an independent risk predictor of 1-year mortality (FIB4 index: p<0.001, HR 1.06, 95% CI 1.035–1.087, CKD: p=0.004, HR 1.834, 95% CI 1.213–2.773, respectively) in patients with ADHF.
A baseline model for prediction of 1-year mortality was determined by multivariable logistic regression including age, body mass index, systolic blood pressure, and serum albumin (C-index: 0.688). Adding high FIB4 index and CKD to the baseline model, all of C-index (0.738, p=0.04), NRI (0.122, p=0.067), and IDI (0.024, p=0.004) were improved.

Conclusions
Combination assessment of renal and hepatic dysfunction could improve the predictability of prognosis in patients with ADHF.

Abstract
Abstract
Background
The prognosis of heart failure remains poor similar to the terminal cancer patients, although recent progress in medical treatment. Palliative Prognostic Index (PPI) is a widely used prognostic index for terminal cancer patients (PPI includes: Palliative Performance Scale, oral intake, oedema, dyspnea at rest and delirium), suggesting the short-term prognostic marker of terminal cancer patients.
Purpose
The purpose of this study was to evaluate the impact of PPI on 30-day mortality, 1-year mortality and 1-year events (including all-cause mortality, readmission due to heart failure and new onset of cerebral infarction after hospital discharge) among acute decompensated heart failure (ADHF) patients.
Method
Study subjects comprised of consecutive 764 patients who admitted due to ADHF and followed up for 1-year. PPI were calculated at the time of hospital admission. Study subjects were divided into two groups based on the PPI: L-PPI (PPI<6) and H-PPI (6≤PPI). We calculated the C-index, net reclassification improvement (NRI) and the integrated discrimination improvement (IDI) to evaluate the improvement of prediction ability on 30-day mortality.
Result
H-PPI showed significantly higher 30-day mortality than L-PPI [7.9% vs 2.0%, log rank p<0.001, Hazard retio (HR): 1.26, 95% confidential interval(CI): 1.14–1.37, p<0.001], 1-year mortality [20.0% vs 12.7%, log rank p=0.022, HR 1.15, 95% CI 1.09–1.21, p<0.001]and 1-year events [45.5% vs 31.1%, log rank p<0.001, HR 1.13, 95% CI 1.09–1.17, p<0.001]. Multivariate cox proportional hazard models adjusted with several covariates revealed that PPI was an independent predictor of 30-day mortality (HR: 1.23, 95% CI: 1.10–1.36, p<0.001), 1-year mortality (HR: 1.10, 95% CI: 1.04–1.16, p<0.001) and 1-year events (HR: 1.11, 95% CI: 1.07–1.15, p<0.001), respectively.
A reference model for prediction of 30-day mortality was determined including left ventricular ejection fraction and serum albumin concentration by multivariable logistic regression analysis. (P<0.05) (C-index: 0.720) Adding PPI to the reference model (C-index: 0.773) significantly improved both NRI (0.458, p=0.038) and IDI (0.046, p=0.007), respectively.
Conclusion
We suggest that assessment of PPI showed good prognostic ability for 30-day and 1-year outcome, while PPI provided additional prognostic information in patients with ADHF.

Abstract
Abstract
Background
In the clinical setting, ischemic heart disease (IHD) is a major problem not only in general patients but also in regular hemodialysis (HD) patients. 13ammonia positron emission tomography (13NH3PET) is an established and excellent diagnostic device for IHD. Although coronary flow reserve is the most important index in IHD diagnosis, there are limited data about stress myocardial blood flow (MBF). We investigated the prognosis predictability of stress MBF in all-cause mortality, cardiovascular (CV) mortality and adverse cardiac and cerebrovascular event (MACCE).
Methods and results
A total 438 of HD patients who undergone 13NH3PET for suspected IHD were enrolled. 29 cases were excluded due to revascularization therapy in 60 days. In total we collected 409 eligible cases. All patients were undergone13NH3PET at Nagoya Radiological Diagnosis Foundation. Patients were divided into two group according to the median value of stress MBF levels; low stress MBF group (<2.12) and high stress MBF group (≥2.12). We followed up them up to 4.2 years (median 2.4 years) and collected their data. We evaluated their all-cause mortality, CV mortality and MACCE. Kaplan-Meyer analysis shows that intergroup difference in all-cause mortality (log rank p=0.001, hazard ratio [HR] 0.411, 95% confident interval [CI] 0.261–0.632), CV mortality (log rank p=0.002, HR 0.324, 95% CI 0.157–0.625) and MACCE (log rank p<0.001, HR 0.465, 95% CI 0.324–0.657). Multiple cox analysis that include established risk factors shows CFR is an independent risk factor for all-cause mortality (HR 0.261, 95% CI 0.154–0.442), CV mortality (HR 0.172, 95% CI 0.079–0.374) and MACCE (HR 0.329, 95% CI 0.213–0.503). As a result of the incremental value with C-index, net reclassification improvement (NRI) and integrated discrimination improvement (IDI) when CFR added into a model with established risk factors, each indicator shows adding stress MBF on established risk factors improve the predictability in all-cause mortality, CV mortality and MACCE (all-cause mortality; NRI 0.642, p<0.001, IDI 0.091, p<0.001, CV mortality NRI 0.809, p<0.001, IDI 0.116, p<0.001, MACCE; NRI 0.646, p<0.001, IDI 0.072, p<0.001).
Conclusion
Considering prognosis of HD population, stress MBF is an important and independent predictor for all-cause mortality, CV mortality and MACCE. As a result of our investigation, stress MBF is one of most strong predictors in HD population.

Abstract
Abstract
Background
Atrial functional mitral regurgitation (AFMR) occurs in patients with atrial fibrillation. However, morphological mechanisms of AFMR are poorly understood.
Purpose
The purpose of this study was to examine the morphological characteristics in patients with AFMR.
Methods
Among consecutive 795 patients undergoing initial radiofrequency catheter ablation (RFCA) at our hospital, twenty-five patients with persistent AF accompanied by AFMR (≥ moderate) before RFCA (AFMR group) were studied. Age-matched 25 patients with persistent AF without MR were defined as a control group.
Results
Left ventricular ejection fraction (LVEF) was lower and left atrium volume index was larger in the AFMR group (Table). Mitral valve annulus diameter and length of anterior mitral leaflet (AML) were similar between groups, whereas length of posterior mitral leaflet (PML) was significantly shorter in the AFMR group. Smaller tethering angle of AML (γ in the figure) and shorter tethering height were significantly associated with the occurrence of AFMR, which were different from morphology of functional mitral regurgitation in patients with dilated LV. Multiple regression analysis revealed that less tenting height (p<0.05) and LA dilatation toward the posterior (p<0.01) were significantly related to AFMR.

Abstract
In the present study, variations in ambient gamma dose rate associated with snow cover were examined in a radioactive-contaminated site in Fukushima Prefecture, Japan. The ambient gamma dose rates decreased with increasing snow depth. The reduction trends were different between fresh snow (0.1-0.2 g/cm3) and granular snow (0.3-0.4 g/cm3) depending on snow density. Snow cover water content (snow water equivalent) calculated from snow depth and density was a key parameter governing the reduction in the ambient gamma dose rate. The ambient gamma dose rates reduced to 0.6 and 0.5 at 4 g/cm2 and 8 g/cm2 of snow water equivalent, respectively. Based on gamma-ray flux density distributions, the ambient gamma dose rates from the primary gamma rays decreased more compared to those from scattered gamma rays due to snow cover.

Abstract
Abstract
Background
Catheter ablation (CA) of atrial fibrillation (AF) improves left ventricular ejection fraction (LVEF) and clinical outcomes in patients with left ventricular systolic dysfunction (LVSD). However, predictors of the improvement of LV function and clinical outcomes by CA were poorly understood.
Purpose
We examined the efficacy of CA in AF patients with LVSD and predictive factors associated with clinical outcomes.
Method
Among consecutive 795 patients undergone initial RFCA at our hospital, we studied 51 patients with LVSD (LVEF ≤50%). Improved LVEF more then 5% at 1-year after CA was classified as “responder” to CA. We analyzed clinical variables and echocardiographic parameters before and after the CAs.
Results
In the responder group, LVEF was significantly improved 1-year after catheter ablation compared with the non-responder group. (ΔLVEF 22±12% vs. −1±4%, p<0.001). The responder group was significantly younger, had more non-paroxysmal AF, smaller LV systolic diameter and lower plasma BNP level before CA (Table). Late gadolinium enhancement (LGE)-positive rate in cardiovascular magnetic resonance imaging (CMR) before CA was higher in the non-responder group than in the responder group (100% [6/6] vs. 38% [5/13], p<0.005). After CAs of AF, event-free survival from hospitalization for heart failure was significantly higher in the responder group (Figure) with less AF recurrence (27% vs. 47%, p=0.04) than in the non-responder group.
Baseline characteristics Responder (N=35) Non-Responder (N=16) P value Age, y 62±11 69±8 p<0.01 Male, n (%) 26 (74) 13 (76) NS Non-pAF 26 (74) 4 (24) p<0.01 LAD, mm 48±7 48±8 NS LAVI, ml/m2 54±17 58±20 NS LVDd, mm 54±7 58±10 NS LVDs, mm 43±7 48±10 p=0.05 EF, % 37±8 38±8 NS BNP (pg/ml) 278±225 684±848 p<0.05
Conclusion
Younger age, absence of LV dilatation, lower plasma BNP, or absence of LGE may well predict favorable clinical outcomes after CA in patients with LVSD.

Abstract
Labeling activity data is a central part of the design and evaluation of human activity recognition systems. The performance of the systems greatly depends on the quantity and "quality" of annotations; therefore, it is inevitable to rely on users and to keep them motivated to provide activity labels. While mobile and embedded devices are increasingly using deep learning models to infer user context, we propose to exploit on-device deep learning inference using a long short-term memory (LSTM)-based method to alleviate the labeling effort and ground truth data collection in activity recognition systems using smartphone sensors. The novel idea behind this is that estimated activities are used as feedback for motivating users to collect accurate activity labels. To enable us to perform evaluations, we conduct the experiments with two conditional methods. We compare the proposed method showing estimated activities using on-device deep learning inference with the traditional method showing sentences without estimated activities through smartphone notifications. By evaluating with the dataset gathered, the results show our proposed method has improvements in both data quality (i.e., the performance of a classification model) and data quantity (i.e., the number of data collected) that reflect our method could improve activity data collection, which can enhance human activity recognition systems. We discuss the results, limitations, challenges, and implications for on-device deep learning inference that support activity data collection. Also, we publish the preliminary dataset collected to the research community for activity recognition.

Abstract
In clinical practice, pharmacists are continually required to improve their knowledge and expertise; however, the postgraduate education system for professional development cannot be confidently stated to be well established. The establishment of a systematic and multifaceted educational curriculum should be useful to improve home care and pharmacists' contribution; therefore, we developed a curriculum in collaboration with the university faculty of pharmaceutical sciences, department of pharmacy in hospital, and the Fukuoka Pharmaceutical Association. Class topics were extracted from the "Kanwa-Iryou-Yakugaku", edited by the Japanese Society for Pharmaceutical Palliative Care and Sciences. The items are necessary to perform palliative care as a pharmacist. A class schedule of 6 days (24 classes in total) was formulated. Questionnaires on comprehension degree before and after each class were provided to the participants. Comprehension was assessed on a scale of 1 to 10, where "I do not understand at all" was 1 and "I understand enough" was 10. The average recovery rates of questionnaires from each class were 92.6 % and 88.9 % before and after class, respectively. The average number of participants who completely answered the questionnaire before and after class was 45.6; therefore, these data were analyzed. Comprehension degree on each topic had significantly increased after attendance of all classes (p < 0.01). The comprehension degree of participants of the medical science of palliative care did greatly improve. Consequently, it is clear that the standard education model constructed was meaningful for the professional development of pharmacists in palliative care medicine.

Abstract
Chemotherapy for cancer is increasingly implemented in the outpatient setting. Pharmacists contribute to cancer treatment by conducting counseling during outpatient chemotherapy visits. They provide guidance on drug treatment, side effects, and side effect countermeasures on every visit. However, there have been few economic evaluations of pharmacist involvement in outpatient chemotherapy. Therefore, we performed a cost utility analysis. We assigned usual care (control) and pharmacist counseling to two groups of 19 patients receiving outpatient chemotherapy for breast cancer at Gifu Municipal hospital. Quality of life was measured at three timepoints before and during chemotherapy treatment using the EuroQol 5 dimension instrument (EQ-5D). EQ-5D values across the timepoints were 0.831, 0.757, and 0.791 for the control group, and 0.882, 0.883, and 0.921 for the pharmacist counseling group. The additional cost in the pharmacist counseling group was 2,227 yen per counseling session. The change in quality-adjusted life years (QALY) was a maximum of -0.021±0.186 in the control group and 0.007±0.199 in the pharmacist counseling group. The maximum cost for one QALY was 1,360,558 yen (≈12,460 US dollars). Pharmacists' counseling in outpatient cancer chemotherapy for breast cancer patients had an acceptable incremental cost-effect ratio, contributing to improved patient quality of life without significant additional expenditure to healthcare.

Abstract
The high-accuracy alignment of magnets is a key issue in the development of next-generation light-source rings. To obtain adequate dynamic apertures, the magnets must be aligned to an accuracy of 10 µm or better. Recently, a new technique that utilizes a vibrating wire has attracted attention for this purpose as it can directly determine with high resolution the magnetic centers in a series of multipole magnets on a straight section between bending magnets. In conventional vibrating-wire alignment techniques, wire sag, which causes alignment errors, is determined from the theoretical catenary curve. By contrast, in the present study, we have measured the sag profiles of various wires in the longitudinal direction to micrometer-order accuracy. We concluded that we can reduce deviations of the actual wire sag from the theoretical curve by choosing a suitable wire. By setting up a test bench of a vibrating-wire alignment system for a series of multipole magnet on a straight section, we have achieved the total error of the magnetic-center measurements of micrometer-order in the standard deviation. Moreover, two systematic error factors, the drift of the magnetic centers due to thermal deformations of the magnets after they are excited and the change in the magnetic centers due to reassembly of the magnets after installing the vacuum chamber, are included in practical magnet alignments. We have experimentally investigated these error factors using the test bench.

Abstract
An increased platelet count is often observed in lung cancer patients. Whether and how the platelets affect cancer progression have yet to be established. The aim of the study was to investigate the involvement of the platelet count and mean platelet volume (MPV) in the prognosis and progression of lung cancer patients. This retrospective study included 146 patients with newly diagnosed primary lung cancer. The platelet count and MPV were measured before invasive diagnostic procedures and treatment. These platelet indices, overall survival of the patients, and tumor metastases for each organ were analyzed. On Kaplan-Meier survival analysis, the overall survivals of patients with platelet counts ≤ 244.0 × 109/L or MPV > 9.7 fL were longer than those of patients with platelet counts > 244.0 × 109/L or MPV ≤ 9.7 fL. Cox regression analysis showed that poor performance status, increased platelet count, and increased C-reactive protein were independent prognostic factors. The platelet indices were associated with metastases to bone, soft tissue, and lymph node, in addition to malignant pleural effusion. Increased platelet count and decreased MPV were unfavorable prognostic factors for patients with lung cancer, and they were involved in bone, soft tissue, and lymph node metastases and malignant pleural effusion.

Abstract
OBJECTIVE The impact of postoperative intensive care upon patient outcomes was evaluated by retrospectively investigating the rate of poor outcomes among miscellaneous elective surgical patients with severe comorbidities. DESIGN A retrospective cohort study was carried out. SETTING University hospital. PATIENTS Surgical patients with severe comorbidities. INTERVENTION The outcomes of 1218 surgical patients treated in intensive care units (ICUs) and postsurgical wards (ICU group vs. non-ICU group) were reviewed for poor outcomes (i.e., no discharge or death). A propensity score analysis was used to generate 248 matched pairs of ICU-admitted patients and controls. VARIABLES OF INTEREST Poor outcome rates on postoperative day 90 and mortality on postoperative days 30 and 90. RESULTS No significant between-group differences were observed in terms of poor outcomes on postoperative day 90 [ICU vs. non-ICU: 33/248 (13%) vs. 28/248 (11%), respectively; ICU odds ratio (OR): 1.19, 95% confidence interval (CI), 0.71-2.01, p=0.596] or in between-group differences in terms of mortality on postoperative days 30 and 90 [ICU vs. non-ICU: 4/248 (1.6%) vs. 2/248 (0.8%) on postoperative day 30 and 5/248 (2.0%) vs. 3/248 (1.2%) on day 90, respectively; ICU OR (95% CI), 2.00 (0.37-10.9) and 1.67 (0.40-6.97) for postoperative 30- and 90-day mortality, respectively (p=0.683 and 0.724)]. Low preoperative body weight was negatively correlated to patient outcomes [OR (95% CI): 0.82/10kg (0.70-0.97), p=0.019], whereas regional analgesia combined with general anesthesia was positively correlated to patient outcomes [OR (95% CI): 0.39 (0.69-0.96), p=0.006]. Extra ICU admission was correlated to poor patient outcomes [OR (95% CI): 4.18 (2.23-7.81), p < 0.0001]. CONCLUSIONS Postoperative ICU admission failed to demonstrate any meaningful benefits in patients with severe comorbidities undergoing miscellaneous elective surgeries.

Abstract
OBJECTIVES Although amiodarone may cause neurotoxicity that can affect patient outcomes when used during cardiopulmonary resuscitation (CPR), it has been commonly prescribed during CPR. This study investigated the possible neurotoxic effects of amiodarone in a rat model of transient forebrain ischemia. DESIGN A prospective laboratory animal study was carried out. SETTING Animal laboratory. MATERIALS Male Sprague-Dawley rats. INTERVENTION Eight minutes of forebrain ischemia was induced in rats by bilateral carotid occlusion and hypotension (mean arterial pressure=35mmHg) under isoflurane (1.5%) anesthesia. Amiodarone (0, 50, 100 and 150mg/kg) with saline was injected intraperitoneally 10min after ischemia. Rats given 0mg/kg of amiodarone were used as saline-treated controls. Sham operated rats received no treatment. VARIABLES OF INTEREST Animals were evaluated neurologically on postoperative days 4-7, and histologically after a one-week recovery period. RESULTS The greatest improvement in water maze test performance corresponded to the sham operated group (p=0.015 vs. saline-treated controls). No differences in performance were seen in amiodarone-treated rats compared with saline-treated controls. In the control group, 45% of the CA1 hippocampal neurons survived, compared with 78% in the sham operated group (p=0.009). Neuron survival after ischemia in the amiodarone treatment groups (50, 100 and 150mg/kg) (58%, 40% and 36%, respectively) and in the control rats did not differ significantly. CONCLUSIONS The administration of amiodarone immediately after transient forebrain ischemia did not worsen spatial cognitive function or neuronal survival in the hippocampal CA1 region in rats. The current results must be applied with caution in humans. However, they indicate that the potential neurotoxicity induced by amiodarone during resuscitation after cardiac arrest may be negligible.
