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
Interventional cardiology is gaining greater popularity worldwide with each passing year. Reduction of exposure dose is a very imminent and an important issue in cardiology procedure. Although a newer radiation reduction technique, device and procedure are very valuable and expected, we should consider about therapy technique, radiation technique, devices, and the way to protection. Digital zoom digitally enlarges images in real time by up to 2.5-fold at lower doses than those used with traditional field of view changes. In our phantom examination the average dose reduction of digital zoom was 27%.
Methods and results
This study is designated as single-center, retrospective, not-randomized, observation study. 2101 eligible cases were collected. We assigned the cases of PCI without the use of Digital zoom to the Conventional group and those involving the use of Digital zoom to the Digital zoom group. There were 806 patients in the Conventional group and 1195 in the Digital zoom group. Because we had begun using Digital zoom from January 2015 onwards, all patients in the Conventional group had undergone PCI from January 2013 to December 2014 and all patients in the Digital zoom group had undergone PCI from January 2015 to December 2016. In addition, we calculated the RAK/minute and DAP/minute for an accurate assessment. To minimize the difference of characteristics between two groups, propensity score including all baseline variables was performed. Furthermore, Predictors of radiation exposure were investigated using multivariable least square methods. Inter group differences were observed in DAP, RAK, DAP/min, and RAK/min (Digital zoom group vs conventional group: DAP, 16000 cGy cm2 [from 1st quartile to 3rd quartile; 10300–24400] vs 20700 [13400–29500], p<0.001; DAP/min, 557 cGy cm2/min [392–737] vs 782 [571–1010], p<0.01; RAK, 1590 Gy [990–2410] vs 1850 [1220–2720], p<0.01; RAK/min, 54.7 Gy/min [38.5–73.2] vs 71.2 [51.5–93.0], p<0.01). Even after propensity score matching, intergroup differences in DAP (810 cases), DAP/min (811 cases), RAK (746 cases), and RAK/min (744 cases) persisted. Furthermore, the least squares method showed that Digital zoom is an important predictor of DAP (β=0.17, p<0.01) and RAK (β=0.12, p<0.01).
Conclusion
Digital zoom is an old and cost-free technique, but one of most powerful reduction of exposure method. Propensity score adjustment and least square methods show that digital zoom is one of independent effective method.

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. 13N-ammonia positron emission tomography (13NH3PET) is an established and excellent diagnostic test for IHD. We have reported about the predictability of coronary flow reserve (CFR) in poor prognosis in HD population. Some prior studies show that low CFR predicts poor prognosis for not only cardiovascular event but also all-cause mortality. Although it is well-known that CFR is an important predictor, there are limited data about CFR of patients without myocardial perfusion (MP) abnormality. We investigated the prognostic predictability of adverse cardiac and cerebrovascular event (MACCE) in HD patients without MP abnormality.
Methods
A total 438 of HD patients who underwent 13NH3PET for suspected IHD were enrolled. All patients were underwent 13NH3PET at our facility. After we excluded patients whose summed stress score (SSS) >3, we identified 182 eligible patients. Patients were divided into two group according to the median value of CFR; low CFR group (≤2.405) and high CFR group (>2.405). We followed up them up to 4.2 years (median 2.4 years) and collected their data. We evaluated their major adverse cardiac cerebrovascular event. 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 CFR added into a model with established risk factors.
Results
There were intergroup difference in baseline characteristics: age, gender, prior CVD and diabetes. Kaplan-Meyer analysis shows statistically intergroup difference [log rank p=0.04, hazard ratio (HR) 0.54, 95% confidential interval (CI) 0.30–0.97]. Multivariable cox regression model for MACCE shows CFR is an independent risk factor (p=0.04, HR 0.54, 95% CI 0.30–0.97). As regarding model discrimination, all of C-index (0.82 vs 0.80, p=0.23), NRI (0.51, p<0.01) and IDI (0.03, p=0.03) were greatest in a predicting model with established risk factors plus CFR.
Conclusions
The low CFR group had poor prognosis in MACCE comparing to the high CFR group. CFR would be an independent risk factor for MACCE. Adding CFR on conventional risk factors could more accurately predict MACCE in HD patients, even in patients without MP abnormality.

Abstract
A patient with a large, squarish, or broad face who desires a small, round, or slender face can undergo mandibular contouring surgery to reduce the width of the lower face. The successful correction of a prominent mandibular angle by conventional angle ostectomy has been reported. However, in the majority of patients with a widened facial appearance, both the mandibular angle and part of the mandibular body anterior to it are protuberant laterally, so both must be resected. At our clinic, operations to reduce the width of the lower face have been performed on 76 patients (9 males and 67 females) during the last 5 years. Initially, we employed a combination of shaving of the lateral cortex and multistaged curved cuts of the mandibular angle. This operative technique, however, required a high level of skill and was time-consuming. A retrospective study of the results revealed the following additional drawbacks. The objective of this procedure is, in a sense, to create morphologically analogous mandibles in all patients, but on the one hand, the resulting relief of the mandibular angle tended to lack individuality, and on the other hand, the primary purpose of reducing the width of the lower face was not fully accomplished in some patients. With angle-splitting ostectomy, which we performed at a later date, however, the width of the lower face was efficiently reduced, producing a natural relief of the mandibular angle. If the surgeon in charge has precise anatomic knowledge and performs this on the basis of an accurate preoperative diagnosis and an operative plan, he or she will encounter no particular difficulties during the operation. There were no complications, such as hematoma, infection, or asymmetry, and aesthetic benefits were achieved even in patients with facial asymmetry.

Abstract
A family with Saethre-Chotzen syndrome with or without polydactyly of the great toes is presented. Saethre-Chotzen syndrome with polydactyly of the great toes has been reported as Robinow-Sorauf syndrome. Both syndromes were observed in this family. This suggests that Saethre-Chotzen syndrome and Robinow-Sorauf syndrome fall within the same clinical spectrum, and the cause is a pleiotropic effect, which is variously expressed.

Abstract
The authors encountered an unusual case of recurrent trismus in a patient who had oral synechia, cleft lip and palate, digital anomalies, and external genital anomaly. Mandibular movement was severely restricted by congenital soft-tissue adhesion in the retromolar region. Despite aggressive surgical efforts and postoperative manipulations, limitation of mouth opening recurred soon after each operation. Furthermore, congenital and postoperative soft-tissue adhesion resulted in severe subsequent jaw deformities, which needed combined maxillary and mandibular advancement.
