Abstract
Abstract
Background
The prevalence of heart failure (HF) is increasing in developed countries. Considering the significant socioeconomic burden of HF, nationwide actions against HF are indispensable. To that end, relevant information on regional variations among HF patients are required.
Purpose
We aimed to explore the geographic variations in the characteristics and outcomes of hospitalized HF patients using a nationwide inpatient database.
Methods and results
Using the Diagnosis Procedure Combination database which is a nationwide inpatient database in Japan, we carried out a comprehensive analysis of 447,818 hospitalized patients with HF (median age 81 years, 238,192 men) who were admitted between January 2010 and March 2018 in Japan. We divided the study population into seven geographical regions based on the location of the admitted hospital. Background characteristics were almost similar among all seven regions. The implementation rates of intubation, hemodialysis, inotropic agent, and advanced circulatory supports including intra-aortic balloon pumping and extracorporeal membrane oxygenation varied among the seven regions. There was a significant difference in the length of hospital stay and the in-hospital mortality among the seven regions. The multivariable logistic regression analysis including baseline clinical charasteristics and medication administered within two days after hospital admission fitted with a generalized estimation equation for in-hospital mortality showed that there was still a significant difference in the in-hospital mortality among the seven regions (Table).
Conclusion
The analysis of a nationwide inpatient database showed that geographical variations existed regarding the outcomes of patients hospitalized for HF. This suggests the necessity of further efforts to establish a standardized medical care system in this era of HF pandemic.

Abstract
Background Intraperitoneal arterial hemorrhage without trauma is extremely rare. We report two infant cases of intraperitoneal arterial hemorrhage due to intestinal duplication. Case presentation In case 1, a 2-month-old girl experienced sudden intraperitoneal hemorrhage from the middle colic artery with no apparent trauma. Hemostasis was achieved with suturing of the hemorrhage point, but the cause of hemorrhage was still unknown. Computed tomography after the first operation revealed a duodenal duplication cyst and a pseudopancreatic cyst. Percutaneous drainage of the pseudopancreatic cyst was performed, and the contents had high pancreatic amylase. As the size of the duodenal duplication cyst also decreased with this drainage, we suspected that the duodenal duplication cyst was connected to the pseudopancreatic cyst and the arterial hemorrhage. We hypothesized that the pancreatic juice inside the duplication cyst leaked into the intraperitoneal cavity and caused rupture of the arterial wall. Therefore, marsupialization of the duodenal duplication was performed to evacuate the pancreatic juice contained in the cyst toward the native duodenum. The postoperative course was uneventful. In case 2, a 6-month-old boy experienced sudden intraperitoneal hemorrhage without trauma. The hemorrhage site was identified as the ileocecal artery, and hemostasis was achieved with sutures. Tissue near the hemorrhage point was biopsied, because the cause of arterial wall rupture was still unknown. The biopsied tissue was found to be intestinal mucosa. The patient had recurrent abdominal pain after the first operation, and computed tomography showed a duplication cyst located near the hemorrhage point. Therefore, we resected the intestinal duplication. Pathology results showed that the intestinal duplication contained intestinal mucosa, ectopic gastric mucosa, and pancreatic tissue. The postoperative course was uneventful. Conclusion Intraperitoneal arterial hemorrhage without trauma is an extremely rare condition, and identifying its cause is difficult. To our knowledge, this is the first report of intraperitoneal arterial hemorrhage due to intestinal duplication. In cases of unexplained intraperitoneal arterial hemorrhage in infants, intestinal duplication near the hemorrhage point should be suspected.

Abstract
In vitro-in vivo extrapolation (IVIVE) using human liver microsomes has been widely used to predict metabolic clearance, but some of the factors used in the process of prediction show variability for the same compound: notably, microsomal intrinsic clearance values corrected by the unbound fraction (CLint, u), physiological parameters used for scale-up, and the source of in vivo clearance data.The purpose of this study was to assess the correlation between in vitro and in vivo CLint with a focus on factors showing variability using four cytochrome P450 (CYP)3A substrates.We surveyed in vivo clearance values in literature and also determined the microsomal CLint, u values. A scaling factor (SFdirect) was defined as in vivo CLint divided by the microsomal CLint, u, which ranged from 1190 to 2310 (mg protein per kg body weight). The application of a mean SFdirect of 1600 (mg protein per kg body weight) and further normalization by the microsomal CLint, u values of midazolam, the most commonly used substrate, resulted in improved prediction accuracy for CLint, u values from various microsomal batches.The results suggest the normalization of variability might be useful for predicting the in vivo CLint.

Abstract
The excitation functions for quasielastic scattering of ^{22}Ne+^{248}Cm, ^{26}Mg+^{248}Cm, and ^{48}Ca+^{238}U are measured using a gas-filled recoil ion separator. The quasielastic barrier distributions are extracted for these systems and are compared with coupled-channel calculations. The results indicate that the barrier distribution is affected dominantly by deformation of the actinide target nuclei, but also by vibrational or rotational excitations of the projectile nuclei, as well as neutron transfer processes before capture. From a comparison between the experimental barrier distributions and the evaporation residue cross sections for Sg (Z=106), Hs (108), Cn (112), and Lv (116), it is suggested that the hot fusion reactions take advantage of a compact collision, where the projectile approaches along the short axis of a prolately deformed nucleus. A new method is proposed to estimate the optimum incident energy to synthesize unknown superheavy nuclei using the barrier distribution.

Abstract
Chronic nonbacterial osteomyelitis is a rare bone disorder that can be found in the jaw. It is often associated with systemic conditions, including autoimmune deficiencies. However, little is known about how the genetic and immunologic background of patients influences the disease. Here, we focus on human leukocyte antigen (HLA), killer cell immunoglobulin-like receptors (KIRs), and their specific combinations that have been difficult to analyze owing to their high diversity. We employed a recently developed technology of simultaneous typing of HLA alleles and KIR haplotype and investigated alleles of the 35 HLA loci and KIR haplotypes composed of centromeric and telomeric motifs in 18 cases and 18 controls for discovery and 472 independent controls for validation. We identified an amino acid substitution of threonine at position 94 of HLA-C in combination with the telomeric KIR genotype of haplotype tA01/tB01 that had significantly higher frequency (>20%) in the case population than in both control populations. Multiple logistic regression analysis based on a dominant model with adjustments for age and sex revealed and validated its statistical significance and high predictive accuracy (C-statistic ≥0.85). Structure-based analysis revealed that the combination of the amino acid change in HLA-C and the telomeric genotype tA01/tB01 could be associated with lower stability of HLA-C. This is the first case-control study of a rare disease that employed the latest sequencing technology enabling simultaneous typing and investigated amino acid polymorphisms at HLA loci in combination with KIR haplotype.

Abstract
OBJECTIVE Vertical jump height and oral function affect the general muscle condition. This study aimed to evaluate the association between vertical jump height and oral function among healthy older individuals. BASIC RESEARCH DESIGN Cross-sectional analytic study. PARTICIPANTS 231 independent older people (mean age, 74.4 ± 5.6 years) who participated in the Kyoto Elders Physical Fitness Measurement Research Project. Individuals with partial or complete edentulousness who did not use a prosthetic device or complained of oral/maxillofacial pain were excluded from the study. INTERVENTIONS Grip strength was measured using a Smedley Hand Dynamometer. To measure masticatory performance, the participants were instructed to chew a gummy jelly on their habitual chewing side (left or right) for 20 s. Occlusal force, contact area, and pressure were also assessed. MAIN OUTCOME MEASURES The outcome variable was vertical jump height. The predictor variables were physical status (age, body mass index, and grip strength), oral status (number of present teeth and denture use), and oral function (masticatory performance, occlusal force, occlusal contact area, occlusal pressure, and tongue pressure). These relationships were evaluated with univariate analysis, and then multiple regression analysis was performed with age as the covariate for each male and female participant. RESULTS Vertical jump height was significantly associated with grip strength in both men and women. Moreover, in women, it was associated with masticatory performance, occlusal force, and occlusal contact area. CONCLUSIONS Vertical jump height was closely associated with oral function among healthy older women.

Abstract
Continuous cell monitoring is very important for the maintenance and control of cell multiplication and differentiation. This paper presents a compact microplate reader that is able to continuously measure a 24-well microplate (6 × 4 wells) using the optical absorption measurement method. The 24-channel plate reader consisted of a spatial filter, light emitting diode light source, and color sensors and was similarly sized with the cell culture microwell plates. A spatial filter was previously fabricated by our group using silicone optical technology (SOT). This SOT-based spatial filter has an excellent noise reduction effect. Light reflection at the optical path interface can be absorbed and only forward light can be transmitted; accordingly, a larger S/N ratio than that of conventional optical systems is expected. The fabricated 24-channel plate reader permits real-time cell monitoring during cultivation on the clean bench and in cell culture conditions by incorporating the SOT spatial filter. Using the device, it was possible to continuously evaluate the concentration and pH of reagents in the 24 wells in real time. Moreover, cell activity and protein production were detectable using the device. These results suggest that the newly fabricated device is a promising tool for the evaluation of cell behaviors for cell management.

Abstract
Purpose: We compared laparoscopic redo fundoplications performed for failed laparoscopic Toupet fundoplication (LTF) and failed laparoscopic Nissen fundoplications (LNFs). Methods: Redo LTF (R-LTF; n = 4) and redo LNF (R-LNF; n = 6) performed between 2007 and 2014 were assessed retrospectively for severity of intraperitoneal adhesions on a scale of 0–3, identification/preservation of the anterior/posterior/hepatic branches of the vagus nerve (VN), complications, and outcome. Results: Redos were performed after a mean of 34 months in R-LTF and 32 months in R-LNF (P = ns) indicated for sliding hernia (n = 3; 2 with partial wrap dehiscence) and partial wrap dehiscence (n = 1) in R-LTF and sliding hernia (n = 6; 4 with partial wrap dehiscence) in R-LNF. The mean adhesion severity score was 1.5 in R-LTF and 2.5 in R-LNF (P < 0.05). The mean number of VN branches identified/preserved was 2.0 in R-LTF and 0.8 in R-LNF (P < 0.05). Mean operative times and mean blood loss were similar. Intraoperative complications were accidental local trauma (n = 1 in R-LTF and n = 3 in R-LNF, one requiring conversion to open repair) (P = ns). Gastric outlet obstruction developed in two R-LNF cases; both were managed conservatively. There have been no further recurrences to date. Conclusion: Although our series is small, adhesions were less, and identification/preservation of VN was easier during R-LTF.

Abstract
PURPOSE The aim of this study was to confirm laryngotracheal growth and recurrent laryngeal nerve (RLN) preservation after partial cricotracheal resection (PCTR) in a growing rabbit model by performing the procedure in pediatric animals. METHODS Six female Japanese white rabbits, 12 weeks of age, underwent PCTR. The course of the RLN was evaluated during surgery (n = 3). Endoscopic and histologic examinations were performed at 22 weeks of age (n = 6). Four non-operated rabbits, 22 weeks of age, underwent endoscopic and histologic examinations as controls. RESULTS The RLN was preserved at the esophageal side and entered the larynx behind the cricothyroid joint after PCTR. Endoscopic examination showed normal vocal cord movements and the large reconstructed subglottis. Histologically, sufficient submucosal vessels and cartilage growth were identified at the reconstructed larynx. The median inside luminal area at the anastomotic site in the PCTR group was 24.8 mm2 (range 21.8-29.0 mm2), and that at the cricoid cartilage and trachea in the control group was 23.4 mm2 (range 20.0-26.6 mm2) and 25.6 mm2 (range 22.9-28.8 mm2), respectively. CONCLUSION No interference with laryngotracheal growth was seen, and RLN preservation was confirmed after PCTR. Use of PCTR in the pediatric age group seems appropriate.

Abstract
PURPOSE This study aimed to investigate the clinical features and risk factors of bile duct perforation in pediatric congenital biliary dilatation (CBD) patients. METHODS CBD patients, whose initial symptom was abdominal pain, were enrolled in this study and were divided into perforated and non-perforated groups. The clinical features of the perforated group were investigated. Moreover, the age at operation, sex, and morphologic features of the extrahepatic bile duct were compared between the groups. RESULTS Fifteen cases of bile duct perforation (10.4%) were identified among the 144 CBD patients who had abdominal pain. Majority of bile duct perforation occurred in patients aged < 4 years. The median duration from onset of abdominal pain to bile duct perforation was 6 (4-14) days. Age at onset [< 4 years old; P = 0.02, OR 13.9, (1.663, 115.3)], shape of extrahepatic bile duct [non-cystic type; P = 0.009, OR 8.36, (1.683, 41.5)], and dilatation of the common channel [P = 0.02, OR 13.6, (1.651, 111.5)] were risk factors of bile duct perforation. CONCLUSIONS Emergent bile duct drainage might be planned to prevent bile duct perforation if CBD patients have the abovementioned risk factors and experience persistent abdominal pain lasting for a few days from onset.

Abstract
Abstract
Background
Improving patients' oral hygiene is an option for preventing postoperative pneumonia that may be caused by aspiration of oral and pharyngeal secretions. Whether preoperative oral care by a dentist can decrease postoperative complications remains controversial. A retrospective cohort study was undertaken to assess the association between preoperative oral care and postoperative complications among patients who underwent major cancer surgery.
Methods
The nationwide administrative claims database in Japan was analysed. Patients were identified who underwent resection of head and neck, oesophageal, gastric, colorectal, lung or liver cancer between May 2012 and December 2015. The primary outcomes were postoperative pneumonia and all-cause mortality within 30 days of surgery. Patient background was adjusted for with inverse probability of treatment weighting using propensity scoring.
Results
Of 509 179 patients studied, 81 632 (16·0 per cent) received preoperative oral care from a dentist. A total of 15 724 patients (3·09 per cent) had postoperative pneumonia and 1734 (0·34 per cent) died within 30 days of surgery. After adjustment for potential confounding factors, preoperative oral care by a dentist was significantly associated with a decrease in postoperative pneumonia (3·28 versus 3·76 per cent; risk difference − 0·48 (95 per cent c.i. −0·64 to−0·32) per cent) and all-cause mortality within 30 days of surgery (0·30 versus 0·42 per cent; risk difference − 0·12 (−0·17 to −0·07) per cent).
Conclusion
Preoperative oral care by a dentist significantly reduced postoperative complications in patients who underwent cancer surgery.

Abstract
INTRODUCTION We compared laparoscopic Toupet fundoplication (LTF) and laparoscopic Nissen fundoplication (LNF) in neurologically normal children. METHODS Forty neurologically normal children who were followed up for more than 3 years after LTF (n = 22) or LNF (n = 18) were reviewed retrospectively. LTF and LNF were performed between 2006 and 2012. RESULTS There were no significant differences in gender (LTF, 15 male and 7 female patients; LNF:, 12 male and 6 female patients), mean age at surgery (LTF vs LNF: 2.5 vs 2.3 years), mean weight at surgery (LTF vs LNF: 9.6 vs 8.9 kg), preoperative symptoms, preoperative pH monitoring (pH <4) (LTF vs LNF: 26.7% vs 21.8%), mean operative time (LTF vs LNF: 117 vs 126 min), postoperative recommencement of enteral feeding (LTF vs LNF: 3.7 vs 3.8 days), or duration of hospitalization (LTF vs LNF: 5.5 vs 6.3 days). Intraoperative complications were esophageal trauma (LTF; n = 1; 4.5%) and liver trauma (LNF; n = 1; 5.6%) (P = 0.70). Post-LTF complications were wrap stenosis (n = 1; 4.5%), and post-LNF complications were wrap stenosis (n = 1; 5.5%) and gastric outlet obstruction (n = 1; 5.5%) (P = 0.43); all were managed conservatively. No case required conversion to open repair. There was no recurrence after LTF, but there were three cases (16.7%) after LNF (P = 0.08). Reoperation was performed at 4, 11, and 13 months, respectively. CONCLUSION Despite LTF and LNF appearing to be equally effective, three LNF cases required reoperation.

The masses of ^{246}Es, ^{251}Fm, and the transfermium nuclei ^{249-252}Md and ^{254}No, produced by hot- and cold-fusion reactions, in the vicinity of the deformed N=152 neutron shell closure, have been directly measured using a multireflection time-of-flight mass spectrograph. The masses of ^{246}Es and ^{249,250,252}Md were measured for the first time. Using the masses of ^{249,250}Md as anchor points for α decay chains, the masses of heavier nuclei, up to ^{261}Bh and ^{266}Mt, were determined. These new masses were compared with theoretical global mass models and demonstrated to be in good agreement with macroscopic-microscopic models in this region. The empirical shell gap parameter δ_{2n} derived from three isotopic masses was updated with the new masses and corroborates the existence of the deformed N=152 neutron shell closure for Md and Lr.

Abstract
Background The pathogenesis of biliary atresia (BA) is still unknown. There are several reports on the etiology of BA, including pancreaticobiliary maljunction (PBM). We experienced a case of Kasai type IIIa BA with PBM, in which we found elevation of pancreatic enzymes in the gallbladder. We evaluated whether PBM is related to the pathogenesis of BA based on our findings. Case presentation The patient was born at 40 weeks of gestation. His body weight at birth was 2850 g. At the age of 4 days, he had an acholic stool and was referred to our hospital. Abdominal ultrasonography showed that triangular cord sign was negative. The gallbladder was isolated with a diameter of 19 mm, and it contracted in response to oral feeding. His ultrasonographic findings were atypical for BA, but his jaundice did not improve. Therefore, we performed an operation at the age of 56 days. Intraoperative cholangiography showed a common bile duct and pancreatic duct and a common channel patent, while the common hepatic duct or intrahepatic duct was not visualized. Bile in the gallbladder contained colorless fluid, which showed elevated lipase level (34,100 IU/L). We performed Kasai portoenterostomy under the diagnosis of Kasai type IIIa BA with PBM. The patient’s postoperative course was uneventful, and he was discharged on day 30 after the operation. Histopathological evaluation showed that the lumens of the common bile duct and cystic duct were patent. However, the common hepatic duct was closed, and only bile ductules with diameters of less than 50 μm were isolated. Infiltration of lymphocytes was detected in the porta hepatis. No apparent inflammation was observed around the cystic duct, which was constantly exposed to pancreatic juice because of reflux through PBM. Conclusions Reflux of pancreatic juice through PBM might not be an etiological factor for BA, but might be associated with patency of the common and cystic bile ducts in Kasai type IIIa BA.

Abstract
INTRODUCTION The aim of this study was to compare laparoscopic hepaticojejunostomy (LHJ) and open hepaticojejunostomy (OHJ) for choledochal cyst associated with hilar hepatic duct stenosis (HHDS). METHODS Data collection was prospective for LHJ cases from 2009 and retrospective for OHJ cases from 2003 to 2008. Data were compared with respect to HHDS. HHDS was incised longitudinally as required during hilar hepatic ductoplasty. RESULTS Fifty-eight subjects were studied (LHJ: n = 27, 4 boys, 23 girls; OHJ: n = 31; 6 boys, 25 girls). HHDS was present in 10 LHJ cases and 10 OHJ cases. Todani classification of choledochal cyst in LHJ patients was type 1A (n = 16) and type 4A (n = 11), and in OHJ patients, it was type 1A (n = 19) and type 4A (n = 12). There were significant differences between LHJ and OHJ with regard to mean operative time (386 vs 341 min), mean blood loss (5.9 vs 18.4 mL), recommencement of enteral feeding (3.9 vs 6.4 days), and hospital stay (11.7 vs 15.5 days) (all P < 0.05). Hepatic ductoplasty was performed in 23 LHJ patients and in 21 OHJ patients. There were no intraoperative complications and no conversions to OHJ. There were no significant differences between LHJ and OHJ, regardless of the presence of HHDS, for postoperative complications, which included minor bile leakage, anastomotic stricture, and intestinal obstruction. CONCLUSION LHJ is as effective as OHJ for the treatment of choledochal cysts irrespective of the presence of HHDS and the need for hepatic ductoplasty.

Abstract
AIMS To investigate changes in glucose tolerance, insulin secretion and insulin sensitivity in Japanese recipients before and 1 year after renal transplantation. METHODS We conducted a study of Japanese recipients without diabetes who underwent renal transplantation at Hokkaido University Hospital. A 75-g oral glucose tolerance test was performed before and 1 year after renal transplantation in these recipients. Insulin sensitivity was estimated using the Matsuda index and homeostasis model assessment of insulin resistance (HOMA-IR). Insulin secretion was evaluated based on the insulin secretion sensitivity index-2 (ISSI-2). RESULTS Of the 62 renal transplant recipients, 31 were diagnosed as having impaired glucose tolerance before transplantation. Among these 31 recipients, after 1 year, four had developed new-onset diabetes after transplantation, and nine had impaired glucose tolerance. Unexpectedly, 18 changed from impaired to normal glucose tolerance. When these recipients with impaired glucose tolerance were classified into a non-amelioration group and an amelioration group, the ISSI-2 was significantly reduced, with no significant changes in the Matsuda index or HOMA-IR, in the non-amelioration group 1 year after renal transplantation. By contrast, ISSI-2 and Matsuda index values were significantly increased, with no significant changes in HOMA-IR values in the amelioration group. CONCLUSIONS More than half of Japanese renal transplant recipients with impaired glucose tolerance had normal glucose tolerance 1 year after renal transplantation. These results suggest that an increase in insulin secretion and whole insulin sensitivity was associated with improvement in glucose tolerance in these recipients.
