Abstract
Influenza D virus (IDV) is one of the causative agents of bovine respiratory disease complex, which is the most common and economically burdensome disease affecting the cattle industry, and the need for an IDV vaccine has been proposed to enhance disease control. IDVs are classified into five genetic lineages based on the coding sequences of the hemagglutinin-esterase-fusion (HEF) protein, an envelope glycoprotein, which is the main target of protective antibodies against IDV infection. Herein, we prepared a panel of monoclonal antibodies (mAbs) against the HEF protein of viruses of various lineages to investigate the antigenic characteristics of IDVs and found that the mAbs could be largely separated into three groups. The first, second, and third groups demonstrated lineage-specific reactivity, cross-reactivity to viruses of multiple but not all lineages, and cross-reactivity to viruses of all lineages, respectively. Analyzing the escape mutant viruses from virus-neutralizing mAbs revealed that the receptor-binding region of the HEF molecule harbors virus-neutralizing epitopes that are conserved across multiple lineage viruses. In contrast, the apex region of the molecule possessed epitopes unique to each lineage virus. Furthermore, reverse genetics-generated recombinant viruses with point mutations revealed that amino acids within positions 210-214 of the HEF protein determined the antigenic specificity of each lineage virus. Taken together, this study reveals considerable antigenic variation among IDV lineages, although they are presumed to form a single serotype in terms of HEF antigenicity. Characterization of the antigenic epitope structure of HEF may contribute to selecting and creating effective vaccine viruses against IDV.IMPORTANCEInfluenza D viruses (IDVs) are suggested to create cross-reactive single serotypes in hemagglutinin-esterase-fusion (HEF) antigenicity, as indicated by serological analyses among distinct HEF lineage viruses. This is supported by the high identities of HEF gene sequences among strains, unlike the hemagglutinin (HA) genes of the influenza A virus that exhibit HA subtypes. Herein, we analyzed HEF antigenicity using a monoclonal antibody panel prepared from several virus lineages and found the existence of lineage-conserved and lineage-specific epitopes in HEF molecules. These findings confirm the HEF commonality and divergence among IDVs and provide useful information for constructing a vaccine containing a recombinant IDV virus with an engineered HEF gene, thereby leading to broad immunogenicity.

Abstract
Group A rotavirus (RVA) sequences were detected in 10.8% (23/212) and 20.7% (87/421) of fecal samples collected in 2017-2022 from wild boars and domestic pigs, using next-generation sequencing. Complete genome sequence analysis of one wild boar and 13 domestic pig RVAs revealed that six of them carried the rare H2 NSP5 genotype. Out of the 39 samples for which the NSP5 genotype could be determined, 23 (59.0%) were of genotype H2. H2 porcine RVAs consist exclusively of Japanese porcine RVAs and exhibit sequence diversity in each segment, suggesting that H2 porcine RVAs may have evolved through reassortment within the Japanese pig population.

Abstract
Influenza D virus (IDV) is a causative agent of the bovine respiratory disease complex (BRDC), which is the most common and costly disease affecting the cattle industry. For developing a candidate vaccine virus against IDV, we sought to produce a temperature-sensitive strain, similar to the live attenuated, cold-adapted vaccine strain available against the influenza A virus (IAV). To this end, we produced a recombinant IDV (designated rD/OK-AL) strain by introducing mutations responsible for the adaptation of the IAV vaccine strain to cold conditions and conferring sensitivity to high temperatures into PB2 and PB1 proteins using reverse genetics. The rD/OK-AL strain grew efficiently at 33 °C but did not grow at 37 °C in the cell culture, indicating its high-temperature sensitivity. In mice, rD/OK-AL was attenuated following intranasal inoculation. It mediated the production of high levels of antibodies against IDV in the serum. When the rD/OK-AL-inoculated mice were challenged with the wild-type virus, the virus was not detected in respiratory organs after the challenge, indicating complete protection against IDV. These results imply that the rD/OK-AL might be a potential candidate for the development of live attenuated vaccines for IDV that can be used to control BRDC.

Abstract
The first bovine parechovirus (Bo_ParV) was reported in 2021, and currently, only two nearly complete genome sequences of Bo_ParV are available. In this study, we detected Bo_ParVs in 10 out of 158 bovine fecal samples tested using real-time RT-PCR, and Bo_ParVs were isolated from three of these samples using MA104 cells. Analysis of the P1 region revealed that Bo_ParVs shared high pairwise amino acid sequence similarity (≥ 95.7% identity), suggesting antigenic similarity among Bo_ParVs, whereas nucleotide sequence identity values (≥ 84.8%) indicated more variability. A recombination breakpoint was identified in the 2B region, which may influence the evolution of this virus.

Abstract
We elucidate how the free-electron-like energy dispersion of theL-gap surface state on a Au(111)-(1 × 1) surface is modified by the experimentally observed uniaxial reconstruction of the topmost atomic layer. For this purpose, we perform a first-principles embedded Green's function calculation for the(22×3)reconstructed semi-infinite Au(111) surface. The obtained band structure unfolded into the surface Brillouin zone of the (1 × 1) surface can be understood in terms of two spin-split parabolic bands centered at theΓ¯point, their umklapp-induced replicas centered at reciprocal lattice vectors of the superlattice (SL) with much weaker intensities, and mini band gaps at the crossing of two of them. More importantly, it is revealed that the band-gap size depends not only on the amplitude of the SL potential but also on mutual spin orientations of two crossing bands. Furthermore, we demonstrate that the band-gap size and the charge density distribution of the surface states are closely correlated with spatial profile of the SL potential.

Abstract
Background: Proper management of adverse events is crucial for the safe and effective implementation of anticancer drug treatment. Showa University Hospital uses our interview sheet (assessment and risk control [ARC] sheet) for the accurate evaluation of adverse events. On the day of anticancer drug treatment, a nurse conducts a face-to-face interview. As a feature of the ARC sheet, by separately describing the symptoms the day before treatment and the day of treatment and sharing the information on the medical record, it is possible to clearly determine the status of adverse events. In this study, we hypothesized that the usefulness and points for improvement of the ARC sheet would be clarified by using and evaluating a patient questionnaire. Methods: This study included 174 patients (144 at Showa University Hospital (Hatanodai Hospital) and 30 at Showa University Koto Toyosu Hospital (Toyosu Hospital) who underwent pre-examination interviews by nurses and received cancer chemotherapy at the outpatient center of Hatanodai and Toyosu Hospital. In the questionnaire survey, the ARC sheet’s content and quality, respondents’ satisfaction, structural strengths, and points for improvement were evaluated on a five-point scale. Results: The patient questionnaire received responses from 160 participants, including the ARC sheet use group (132 people) and the non-use group (28 people). Unlike the ARC sheet non-use group, the ARC sheet use group recognized that the sheet was useful to understand the adverse events of aphthous ulcers (p = 0.017) and dysgeusia (p = 0.006). In the satisfaction survey questionnaire, there was a high sense of security in the pre-examination interviews by nurses using the ARC sheet. Conclusions: The ARC sheet is considered an effective tool for comprehensively evaluating adverse events. Pre-examination interviews by nurses using ARC sheets accurately determined the adverse events experienced by patients with anxiety and tension due to confrontation with physicians.

Abstract
Ferrets are animals that are known to be susceptible to influenza A virus (IAV) infection. To evaluate the risk of IAV transmission from diseased ferrets to humans, we performed a serosurvey to detect specific antibodies against the H1, H3, H5, and H7 subtypes of IAV. We found a high positive rate of the H1 (24.1%) and H3 (5.2%) subtypes in pet ferrets by using an enzyme-linked immunosorbent assay for hemagglutinin proteins. The results were confirmed by the virus-neutralization test for representative antibody-positive serum samples. We also detected hemagglutinin and neuraminidase genes in two ferrets showing acute respiratory illness and whose owner was diagnosed with IAV infection; a human H1N1pdm virus was isolated from one of these ferrets. Our findings suggest that attention should be paid for IAV infection from humans to ferrets, and vice versa.

Abstract
Influenza D virus (IDV) may cause the bovine respiratory disease complex, which is the most common and costly disease affecting the cattle industry. Previously, we revealed that eight segments could be actively packaged in its single virion, suggesting that IDV with the seven-segmented genome shows an agnostic genome packaging mechanism. Herein, we engineered an eight-segmented recombinant IDV in which the NS1 or NS2 genes were separated from NS segment into independent segments (NS1 or NS2 segments, respectively), leading to monocistronic translation of each NS protein. We constructed two plasmids: one for the viral RNA (vRNA)-synthesis of the NS1 segment with a silent mutation at the splicing acceptor site, which controls NS2 transcription in the NS segment; and another for the RNA synthesis of the NS2 segment, with deletion of the intron in the NS segment. These plasmids and six other vRNA-synthesis plasmids were used to fabricate an infectious eight-segmented IDV via reverse genetics. This system enables analysis of the functions of NS1 or NS2. We tested the requirement of the N-terminal overlapping region (NOR) in these proteins for viral infectivity. We rescued a virus with NOR-deleted NS2 protein, which displayed a growth rate equivalent to that of the eight-segmented virus with intact NS2. Thus, the NOR may not influence viral growth. In contrast, a virus with NOR-deleted NS1 protein could not be rescued. These results indicate that the eight-segmented rescue system of IDV may provide an alternative method to analyze viral proteins at the molecular level.

Abstract
Epidemiology of bat Betacoronavirus, subgenus Sarbecovirus is largely unknown, especially outside China. We detected a sarbecovirus phylogenetically related to severe acute respiratory syndrome coronavirus 2 from Rhinolophus cornutus bats in Japan. The sarbecovirus' spike protein specifically recognizes angiotensin-converting enzyme 2 of R. cornutus, but not humans, as an entry receptor.

Abstract
OBJECTIVES Tricuspid valve dysplasia (TVD) and Ebstein's anomaly (EA) diagnosed by fetal echocardiography vary greatly in terms of clinical severity and prognosis. The Celermajer index and Simpson-Andrews-Sharland (SAS) score have been reported previously for the prediction of prognosis in cases of TVD/EA; however, they do not take into account the hemodynamic impact of left ventricular (LV) function, which has recently been implicated as being important in the pathophysiology of TVD/EA. The aim of this study was to develop a novel scoring system that includes LV function for the prediction of perinatal death in fetuses diagnosed with TVD/EA. METHODS The clinical records of 36 fetuses diagnosed prenatally with TVD/EA between 2000 and 2015 in our hospital were reviewed. Univariate analysis was used to assess the association between perinatal death (defined as death between 22 weeks' gestation and 4 weeks after delivery) and gestational age at diagnosis, cardiothoracic area ratio (CTAR), degree of pulmonary artery flow, direction of ductal flow, right-to-left ventricular diameter ratio, tricuspid regurgitation (TR) maximum velocity, Celermajer index, SAS score and LV-Tei index. A new prognostic score, the TRIPP score (TRIcuspid malformation Prognosis Prediction score), was developed using the parameters found to be associated significantly with perinatal death. The predictive value of this score was assessed in an additional nine fetuses diagnosed with TVD/EA. RESULTS Thirty-six fetuses were diagnosed prenatally with TVD/EA, two of which were terminated, one was lost to follow-up and two died before 22 weeks' gestation. Of the 31 included fetuses, 10 (32%) died in the perinatal period. Univariate analysis demonstrated that TR maximum velocity was significantly lower (2.22 ± 0.17 m/s vs 3.26 ± 0.12 m/s; P < 0.001) and SAS score was significantly higher (5.7 ± 0.6 points vs 2.8 ± 0.4 points; P = 0.0014) in cases of perinatal death than in surviving fetuses. The degree of pulmonary artery flow and the direction of ductal flow were also associated significantly with perinatal death (P < 0.01 for both). Notably, LV-Tei index was significantly higher in cases of perinatal death than in surviving fetuses (0.81 ± 0.08 vs 0.50 ± 0.05; P < 0.001). In contrast, there was no significant difference in Celermajer index, CTAR or right-to-left ventricular diameter ratio. Finally, we established a novel combinatorial scoring system, the TRIPP score, including the four significant factors: TR maximum velocity, pulmonary artery flow, direction of ductal flow and LV-Tei index. The TRIPP score was found to predict efficiently perinatal mortality in fetuses with TVD/EA. CONCLUSIONS Our novel combinatorial score of echocardiographic parameters, the TRIPP score, including LV-Tei index, is easy to measure and provides a good tool for the prediction of perinatal mortality in fetuses diagnosed prenatally with TVD/EA.

Abstract
Influenza D virus has been found to cause respiratory diseases in livestock. We surveyed healthy dromedary camels in Ethiopia and found a high seroprevalence for this virus, in contrast to animals co-existing with the camels. Our observation implies that dromedary camels may play an important role in the circulation of influenza D virus.

Abstract
H3N2 canine influenza viruses are prevalent in Asian and North American countries. During circulation of the viruses in dogs, these viruses are occasionally transmitted to cats. If this canine virus causes an epidemic in cats too, sporadic infections may occur in humans because of the close contact between these companion animals and humans, possibly triggering an emergence of mutant viruses with a pandemic potential. In this study, we aimed to gain an insight into the mutations responsible for inter-species transmission of H3N2 virus from dogs to cats. We found that feline CRFK cell-adapted viruses acquired several mutations in multiple genome segments. Among them, HA1-K299R, HA2-T107I, NA-L35R, and M2-W41C mutations individually increased virus growth in CRFK cells. With a combination of these mutations, virus growth further increased not only in CRFK cells but also in other feline fcwf-4 cells. Both HA1-K299R and HA2-T107I mutations increased thermal resistance of the viruses. In addition, HA2-T107I increased the pH requirement for membrane fusion. These findings suggest that the mutations, especially the two HA mutations, identified in this study, might be responsible for adaptation of H3N2 canine influenza viruses in cats.

Abstract
By examining the reconstructed gastric tube during esophagectomy using indocyanine green fluorescence (ICG) angiography, we have established a '90-second rule' to confirm good blood perfusion at the anastomosis site. We examined the surgical outcome (rate of anastomotic leakage) of 70 consecutive patients who underwent esophagectomy with gastric tube reconstruction using ICG fluorescence angiography. All of the anastomoses were made in the area where less than 90 seconds was needed for enhancement using ICG fluorescence angiography (i.e. within the 90-second rule). In 18 cases for which the time until enhancement of the gastric tube tip exceeded 60 seconds, the anastomosis site was decided by reference to the ICG fluorescence angiogram, and the hypoperfused area was excised, and this significantly shortened the median time until enhancement of the gastric tube tip from 95.5 (60.0-204.0) seconds to 41.0 (9.0-77.0) seconds (P < 0.001). In three cases, the anastomosis was made at the site where more than 60 seconds was needed for ICG enhancement. In one case where ICG enhancement had taken 77 seconds, minor anastomotic leakage occurred. The overall rate of anastomotic leakage in this series was 1.4%. Blood flow in the reconstructed gastric tube is sufficient if the anastomosis is made in the area where ICG fluorescence angiography demonstrates enhancement within 60 seconds. Gastric tube necrosis can be avoided if the area showing an enhancement time exceeding 90 seconds is excised. The 90-second rule is a safe and effective method for deciding the site of anastomosis.

Abstract
H9N2 avian influenza viruses are present in poultry worldwide. These viruses are considered to have pandemic potential, because recent isolates can recognize human-type receptor and several sporadic human infections have been reported. In this study, we aimed to identify mutations related to mammalian adaptation of H9N2 influenza virus. We found that mouse-adapted viruses had several mutations in hemagglutinin (HA), PB2, PA, and PB1. Among the detected mutations, PB1-K577E was a novel mutation that had not been previously reported to involve mammalian adaptation. A recombinant H9N2 virus bearing only the PB1-K577E mutation showed enhanced pathogenicity in mice, with increased virus titers in nasal turbinates compared to that in mice infected with the wild-type virus. In addition, the PB1-K577E mutation increased virus polymerase activity in human cell culture at a lower temperature. These data suggest that the PB1-K577E mutation is a novel pathogenicity determinant of H9N2 virus in mice and could be a signature for mammalian adaptation.

Abstract
We conducted a detailed study of lymphangiogenesis and subsequent lymph node metastasis in early-stage esophageal squamous cell carcinoma (ESCC) using immunostaining for D2-40 and vascular endothelial growth factor (VEGF)-C and D. The study materials included 13 samples of normal squamous epithelium, 6 samples of low-grade intraepithelial neoplasia (LGIN), and 60 samples of superficial ESCC (M1 and M2 cancer 24; M3 or deeper cancer 36). We assessed lymphatic vessel density (LVD) using D2-40 and immunoreactivity for VEGF-C and D in relation to histological type, lymphatic invasion, and lymph node metastasis. LVD in M1 and M2 lesions and M3 or deeper lesions was significantly higher than in normal squamous epithelium (P < 0.001). High expression of VEGF-C and D was observed in M1 and M2 cancer and in M3 or deeper cancer, but not in normal squamous epithelium or LGIN. LVD in VEGF-C- and D-positive cases was significantly higher than in negative cases (P < 0.001). In M3 or deeper cancer, the correlation between VEGF-C or D status and lymphatic invasion or lymph node metastasis was not significant. LVD in cases with positive lymphatic invasion and those with lymph node metastasis was significantly higher than in cases lacking either (P = 0.02 and 0.03, respectively). ESCC cells produce VEGF-C and D from the very early stage of progression. VEGF-C and D activate lymphangiogenesis, and this increase of lymphatic vessels leads to lymphatic invasion and subsequent lymph node metastasis.

Abstract
In esophageal squamous cell carcinoma (ESCC) patients who are treated with chemoradiotherapy (CRT), identification of the presence or absence of residual or recurrent carcinoma is usually pivotal in their clinical management. In addition, the extent of carcinoma invasion into the esophageal wall could determine the clinical outcome of these patients following CRT. Therefore, in this study, we evaluated the response to CRT both macroscopically and histologically in a consecutive series of 42 ESCC patients receiving neoadjuvant chemoradiotherapy following curative esophageal resection at Tohoku University Hospital between August 2011 and December 2012. The histological grading of tumor regression was as follows: grade 3, markedly effective (no viable residual tumor cells); grade 2, moderately effective (residual tumor cells in less than one-third of the tumor); grade 1, slightly effective (1b, residual tumor cells in one-third to two-thirds of the tumor; 1a, residual tumor cells in more than two-thirds of the tumor); and grade 0, ineffective. In this study, we selected grade 2 and 1b cases because they might show a complete response with definitive CRT. We evaluated the presence of any residual in situ lesions and tumor depth in detail. The grading of tumor regression in primary sites was as follows: grade 3 (7 cases), grade 2 (16 cases), grade 1b (13 cases), and grade 1a (6 cases). The concordance rate between macroscopic and histopathological evaluation on the depth of the tumor was 40% (17/42). Among 29 cases (grade 2 and grade 1b), intraepithelial lesions were not detected in 17 cases, and tumor nests were not detected in the lamina propria mucosae in 9 cases. The results of this study highlight the difficulties of detecting residual carcinoma cells using conventional endoscopic biopsy in patients who have received CRT. Therefore, when residual cancer is clinically suspected in patients who have received CRT, the biopsy specimen should be obtained from the deep layer of the esophagus whenever possible. Additionally, close follow-up is required using positron emission tomography/computed tomography, endoscopy, and other radiological evaluations.

Abstract
BACKGROUND We performed a clinical and pathological analysis of cases of acute vascular rejection (AVR), characterized by intimal arteritis and transmural arteritis (Banff v score) after kidney transplantation, in an attempt to clarify the mechanisms underlying the development and prognostic significance of AVR. METHODS AVR (Banff score: v >0) was diagnosed in 31 renal allograft biopsy specimens (BS) obtained from 31 renal transplant patients receiving follow-up care at the Department of Urology, Tokyo Women's Medical University, between January 2010 and April 2016. RESULTS AVR was diagnosed at a median of 124.6 days after transplantation. Among the 31 BS showing evidence of AVR, AVR was mild (v1 in Banff's classification) in 25 cases, moderate (v2) in 6, and severe (v3) in none. We classified the 31 BS with evidence of AVR by their overall histopathological features as follows: isolated v lesions were observed in 6 BS, acute antibody-mediated rejection (AAMR) in 7, acute T-cell-mediated rejection (ATCMR) in 12, and both ATCR and AAMR in 6. Loss of the renal allograft occurred during the observation period in 3 patients, and, of the remaining cases with functioning grafts, deterioration of renal allograft function after biopsy occurred in only 2 patients. CONCLUSIONS The results of our study suggest that ATCMR contributes to AVR in 40% to 60% of cases, AAMR in 20% to 40% of cases, and isolated v lesions in 20% of cases. The prognosis of the patient with the graft that had AVR was relatively good under the present immunosuppression protocol and current anti-rejection therapies.

Abstract
Influenza (flu) D virus, a possible causative agent of bovine respiratory disease, is
genetically classified into three clusters: D/OK-, D/660-, and D/Japan-lineages. To
evaluate antigenic heterogeneity among these clusters, we compared antibody titers to each
lineage virus using bovine sera collected over time following virus infection. Antibody
titers to D/Japan-lineage virus rose rapidly in the acute phase of infection, and were 4
times higher than those to the other clustered viruses. In the later phase of infection,
titers to D/Japan-lineage virus were equivalent to those to D/OK-lineage virus, and still
higher than those to D/660-lineage virus. These results suggest the existence of common
and lineage-specific antigenic epitopes in the hemagglutinin-esterase-fusion protein of
flu D viruses.

Abstract
BACKGROUND Among infectious diseases, influenza is the most common cause of infection in Japan and worldwide. We aimed to evaluate the effect of influenza vaccination in kidney transplantation (KTx) recipients. METHODS We retrospectively evaluated the records of 98 participants who underwent KTx at our institution between March 2009 and May 2016. All patients received tacrolimus or cyclosporine, mycophenolate mofetil, and methylprednisolone for maintenance immunosuppression after KTx. In accordance with the criteria of our institution, everolimus was administered for the maintenance of immunosuppression after KTx. We compared the rate of influenza infection during the 2016-2017 season (8 months, from October 2016-May 2017) between KTx patients treated with 1 or 2 doses of influenza vaccine (treatment group, n = 71) and KTx patients who did not receive a vaccine (nontreatment group, n = 27). RESULTS Among patient characteristics, only the prevalence of diabetes mellitus differed significantly between the groups (treatment group: 9.9%, 7 of 71 patients; nontreatment group: 29.6%, 8 of 21 patients; P = .02). Influenza infection occurred at similar rates in the 2 groups (treatment group, 5.63% 4 of 71 patients; nontreatment group: 3.70%, 1 of 27 patients; P = .70). CONCLUSIONS Among KTx patients managed in our institution, treatment with 1 or 2 doses of influenza vaccine did not reduce the rate of influenza infection in the 2016-2017 season, suggesting that influenza vaccination may currently be ineffective in KTx patients.

Abstract
We report a case of living related renal transplantation that used the recipient's saphenous vein as a graft to extend the length of the right donor renal vein. A 41-year-old woman underwent ABO-incompatible living related renal transplantation from her 74-year-old mother in November 2014. A retroperitoneal laparoscopic right donor nephrectomy was performed, because the right kidney showed a cyst on preoperative computed tomography. As the right kidney after donor nephrectomy had a short renal vein and the kidney was large at 280 g, anastomosis with the external iliac vein was difficult. Therefore, we obtained the recipient's 15-cm-long right saphenous vein and created a 1 cm saphenous vein graft. We anastomosed 1 side of the saphenous vein graft to the allograft renal vein in bench surgery and performed end-to-side anastomosis of the other end to the recipient's external iliac vein. The allograft renal artery was used to perform end-to-end anastomosis to the recipient's internal iliac artery. Allograft kidney function was good after transplantation. When the longer axis of the renal graft vein is short, as in the right kidney, a saphenous vein graft may be useful.

Abstract
OBJECTIVES We aimed to evaluate the feasibility and efficacy of surgical prostatectomy in renal transplant recipients (RTRs). METHODS Between January 2008 and February 2017, we identified 13 RTRs who were diagnosed with localized prostate cancer and underwent radical prostatectomy. We reviewed all available clinicopathologic data for these 13 patients. RESULTS The median patient age was 61 years and median serum prostate-specific antigen (PSA) was 8.79 ng/mL. The mean period between transplantation and diagnosis of prostate cancer was 136 months. The sources for the kidney transplants included 10 living and 3 deceased donors. Biopsies indicated that the Gleason scores were 7 in 10 patients and 8 to 10 in 3 patients. Meanwhile, the D'Amico risk classification indicated an intermediate risk in 9 patients and a high risk in 4 patients. Eight patients were at stage cT1 and 5 were at stage cT2. The surgical procedure was retropubic radical prostatectomy in one recipient, laparoscopic radical prostatectomy in 3 recipients, and robot-assisted radical prostatectomy in 9 RTRs. Intraoperative complications were not noted in any patient, although one patient demonstrated postoperative complications (Clavien grade ≥ 3). An indwelling urinary catheter was required in 3 patients for over 3 weeks due to delayed wound healing. Biochemical recurrence evaluated by PSA monitoring occurred in four patients. Postoperative graft function was stable in all but one patient who required resumption of dialysis before prostatectomy; however, all patients are alive at the time of publication with 12 patients showing well-functioning renal allografts. CONCLUSION Prostatectomy may be a feasible and effective technique as an initial treatment for RTRs with localized prostate cancer.

Abstract
Summary
Objective:
We created and validated a Markov model to simulate the prognosis with treatment for HCV-related hepatocellular carcinoma (HCC) for assessment of cost-effectiveness for alternative treatments of HCC.
Method:
Markov state incorporated into the model consisted of the treatment as a surrogate for HCC stage and underlying liver function. Retrospective data of 793 patients from three university hospitals were used to determine Kaplan-Meier survival curves for each treatment and transition probabilities were derived from them.
Results:
There was substantial overlap in the 95% CIs of the Markov model predicted and the Kaplan-Meier survival curves for each therapy. The predicted survival curves were also similar with those from the nationwide survey data supporting the external validity of our model.
Conclusions:
Our Markov model estimates for prognosis with HCC have both internal and external validity and should be considered applicable for estimating cost-effectiveness related to HCC.

Abstract
The clarification of public concerns regarding heart transplantation is important for improving low organ donation rates in Japan. In the present study, we used the Twitter data of 4986 tweets (between August 2015 and January 2016) and 1429 tweets (between April 2016 and May 2016) to analyze public discourse on heart transplantation in Japan and identify the reasons for low organ donation rates. We manually categorized all tweets relevant to heart transplantation into nine categories and counted the number of tweets in each category per month. During the study period, the most popular category of tweets was related to the media, followed by money (tweets questioning or even criticizing the high price of fundraising goals to go overseas for heart transplantations), while some tweets were misconceptions. We also conducted a sentiment analysis, which revealed that the most popular negative tweets were related to money, while the most positive tweets were related to reports on the favorable outcomes of recipients. Our results suggest that listening to concerns, providing correct information (particularly for some misconceptions), and emphasizing the outcomes of recipients will facilitate an increase in the number of people contemplating heart transplantation and organ donation.

Abstract
BACKGROUND Previously, we explored the histopathologic characteristics of medullary ray injury (MRI) inducing interstitial fibrosis and tubular atrophy (IF/TA) to determine its etiologies, which include calcineurin inhibitor (CNI) toxicity and urologic complications. However, we did not examine the effects of these etiologies on long-term kidney allograft prognosis, because biopsy timing differed among cases. AIM We examined the influence of early MRI on kidney allograft prognosis using protocol biopsies taken within a 3-month time frame. METHODS We defined early MRI as tubular degeneration with interstitial edema or mild fibrosis localized to the medullary ray. We divided 53 protocol biopsies into 2 groups, with and without early MRI. Early MRI+ cases with isometric vacuolization were classified as CNI toxicity; those with Tamm-Horsfall protein in the interstitium and a thyroidlike appearance were classified as urinary tract system abnormalities; remaining cases were classified as "others." We compared changes in serum levels of creatinine (sCr) over 3 years and fibrosis extent at 1 year. RESULTS The sCr levels were significantly higher in the MRI+ group than the MRI- group at 3 years (P = .024). Examining the 3 MRI+ subgroups, only the MRI+ urinary tract system abnormalities group had significantly high sCr levels compared to the MRI- group (P = .019). The MRI+ group showed significant signs of IF/TA at 1 year. CONCLUSIONS Early MRI after kidney transplantation was significantly more likely to develop IF/TA at 1 year and had higher sCr levels at 3 years. In such cases, intervention might preserve graft function over the long term.

Abstract
A persistent hepatitis B virus (HBV) infection is characterized by a lack of or a weak immune response to HBV, which may be reflective of tolerance to HBV. Efficient induction of HBV-specific immune response leads to the clearance of HBV in patients with a chronic HBV infection. CpG oligodeoxynucleotides (ODN) has a powerful adjuvant effect in HBV vaccination. A recent report demonstrated that the immunization by B/K CpG ODN (K3) wrapped by the nonagonistic Dectin-1 ligand, schizophyllan (SPG), namely K3-SPG, was more effective in the induction of antigen-specific immune response than that by K3. In this study, we examined the efficacy of K3-SPG as a HBV vaccine adjuvant. Wild-type (WT) mice and HBV transgenic (HBV-Tg) mice were subcutaneously immunized with hepatitis B surface antigen (HBsAg) alone, HBsAg and K3, or HBsAg and K3-SPG. The vaccination with HBsAg and K3-SPG significantly enhanced humoral and cellular immune response to HBV antigen compared to the other vaccinations in WT and HBV-Tg mice. K3-SPG induced the accumulation of dendritic cells (DCs) into draining lymph node and the activation of DCs. The expression of cytokines and chemokines related to Th1 and Th2 responses was upregulated after the vaccination including with K3-SPG. In conclusion, these results indicated that the vaccination using K3-SPG may overcome tolerance even in patients with chronic HBV infection.

Abstract
We calculate the decay length in surface normal direction of the surface-state wave functions on a clean Bi(1 1 1) surface as a function of two-dimensional (2D) wave vector [Formula: see text] along the [Formula: see text] line. For this purpose, we perform a first-principles density functional theory (DFT) calculation for semi-infinite Bi(1 1 1) by employing the surface embedded Green's function technique. The decay length of the two surface bands is found to be ∼24 Bi bilayers at [Formula: see text], while it remains less than 5 Bi bilayers when [Formula: see text] is away from [Formula: see text] and [Formula: see text]. At [Formula: see text], the degenerate surface bands are split from the upper boundary energy of the projected bulk valence bands only by 5 meV. In spite of this, the decay length of these bands at [Formula: see text] is less than 10 Bi bilayers due to the large effective mass (small curvature) of the highest valence band in the surface normal direction.

Abstract
BACKGROUND Persistent hyperparathyroidism in kidney transplant recipients may be prolonged for a few years, and in these cases, parathyroidectomy is indicated even if graft function is satisfactory. The aim of this study was to characterize the parathyroid glands in long-term dialysis recipients and determine the pathogenesis of persistent hyperparathyroidism. METHODS We analyzed 44 parathyroid glands resected from 11 patients who underwent parathyroidectomy after kidney transplantation. The histopathologic types and weights of all the parathyroid glands were evaluated. RESULTS The mean dialysis period was 15.8 years, and the time from kidney transplantation to parathyroidectomy ranged from 3.5 to 89 months. Nodular hyperplasia was present in parathyroid glands in all cases. The mean glandular weight was 396.0 ± 299.0 mg, and the maximum glandular weight was 3200 mg. Seven patients who underwent parathyroidectomy >1 year after kidney transplantation (late PT) were compared with 4 patients who underwent parathyroidectomy within 10 months after transplantation (early PT). The maximum (442.9 vs 1503 mg; P = .018) and mean (312.5 ± 177.4 mg vs 1135.6 ± 977.7 mg; P = .001) glandular weights were significantly lower in patients who underwent late PT compared with those who received early PT. Based on the histopathologic type and glandular weight of each parathyroid gland, nodular hyperplasia in glands ≤150 mg was common in patients who underwent late PT. CONCLUSIONS The presence of nodular hyperplasia in parathyroid glands with a low weight may be involved in long-lasting persistent hyperparathyroidism in patients undergoing long-term dialysis.

Abstract
OBJECTIVES Malignant pleural effusion (MPE) has a poor prognosis. Most patients are treated with tube thoracostomy and sclerotherapy, although its success rate is around 64%. We have investigated intrapleural perfusion with hyperthermic chemotherapy (IPHC) using cisplatin in a study with a pharmacokinetic evaluation. METHODS Patients with MPE, performance status of 0-1, possibility of good lung expansion and Cr<1.2mg/dL were treated with IPHC. The circuit was filled with 2000mL of normal saline containing cisplatin at a dose of 80mg/m2. Under video-assisted thoracoscopic surgery, the thoracic cavity was filled and perfused at a speed of approximately 1L/min at a temperature of 43°C for 1h. Perfusion solution and plasma samples were periodically collected, and concentrations of protein-unbound (free) platinum, which was the active derivative of cisplatin, and total platinum were determined by flameless atomic absorption spectrometry. RESULTS Twenty patients with MPE (8 lung cancers, 7 mesotheliomas, and 5 others) were enrolled in this study. Rate of free platinum concentration relative to total platinum concentration in perfusion solution after 1hr IPHC at 43°C was 61.1±12.9%. Area under curve (AUC) of free platinum in the pleural space was calculated to be 26.3μg/mLxh, resulting in complete control of pleural effusion for 3 months after IHPC in all cases (95% confidence interval: 83-100%). While, absorption rate of total platinum from the pleural space was 33.8±17.0% (27.4±13.6mg/m2), and the maximum concentration of total platinum in serum was low, 0.66±0.31μg/mL, resulting in controllable side effects; grade 1 renal toxicity: 6 patients, grade 1 emesis: 7 patients. CONCLUSIONS IPHC with cisplatin showed favorable pharmacokinetic profiles for an optional treatment to control malignant pleural effusion.

Abstract
BACKGROUND An equation for the estimated glomerular filtration rate (eGFR) is generally used for evaluating renal function in Japan. OBJECTIVE To assess the accuracy of the preoperative eGFR for estimating kidney donors' measured glomerular filtration rate (mGFR). METHODS Between April 2009 and August 2014, 91 Japanese living kidney donors were included in this study. The eGFR was calculated as follows: eGFR = 194 × serum creatinine(-1.094) × Age(-0.287) (and × 0.739 for women), and the mGFR was evaluated using inulin clearance. The preoperative eGFR was then compared with the mGFR. RESULTS Patients included 27 men and 64 women with a mean age of 56.8 ± 9.5 years (range, 36-79 years), mean body surface area of 1.56 ± 0.14 m(2) (range 1.27-1.92 m(2)), mean body mass index of 22.3 ± 2.3 kg/m(2) (range 14.0-27.0 kg/m(2)), and mean serum creatinine level of 0.66 ± 0.14 mg/dL (range 0.39-0.97 mg/dL). The mean eGFR was 81.3 ± 14.2 mL/min/1.73 m(2) (range 45.5-125.9 mL/min/1.73 m(2)), and the mean mGFR was 89.0 ± 15.5 mL/min/1.73 m(2) (range 45.4-130.7 mL/min/1.73 m(2)). The eGFR was significantly lower than the mGFR (P < .001). The correlation coefficient for the relationship between the eGFR and mGFR values was 0.503, and the mean difference between the 2 values was -7.8 (8.7%). CONCLUSIONS Although the eGFR correlated with the mGFR, the eGFR values did not accurately estimate the mGFR in living kidney donors. Therefore, it is necessary to evaluate the mGFR, especially in marginal kidney donors.
