Abstract
INTRODUCTION Several calcimimetics, other than cinacalcet, are commercially available; however, their effects on calcium and phosphate levels have not yet been fully studied. We conducted a systematic review and meta-analysis of randomized controlled trials to evaluate the impact of calcimimetics on the management of serum calcium and phosphate levels in patients with secondary hyperparathyroidism undergoing dialysis. METHODS A systematic literature search through October 2023 and a meta-analysis were conducted on the effects of upacicalcet, etelcalcetide, evocalcet, and cinacalcet on serum calcium and phosphate levels in patients with secondary hyperparathyroidism undergoing dialysis; we searched PubMed, Ovid MEDLINE, and the Cochrane Central Register of Controlled Trials, and 21 studies comprising 6371 patients undergoing dialysis were included. RESULTS Participants treated with calcimimetics had lower serum calcium and phosphate levels than placebo. CONCLUSION Calcimimetics significantly reduced serum calcium and phosphate levels compared to placebo in patients with secondary hyperparathyroidism undergoing dialysis, independent of therapeutic strategy or concomitant vitamin D treatment.

Abstract
BACKGROUND Hyponatremia is a common and important electrolyte disorder. However, the prevalence and factors associated with hyponatremia in patients with chronic kidney disease (CKD) are unknown. METHODS We studied the factors associated with hyponatremia (< 135 mEq/L) in CKD patients registered in the Fukuoka Kidney Disease Registry (FKR) study using a logistic regression model variable selected using the variable reduction method. RESULTS We analyzed the baseline characteristics of 4367 participants with CKD (age, 64 ± 16 years; male, 56.1%). Hyponatremia was detected in 2.0% of the patients at baseline, and multivariate logistic analysis showed that the independent factors for hyponatremia were body mass index (odds ratio [OR] 0.91; 95% confidence interval [CI] 0.85-0.97), prescription of benzodiazepine (OR 2.31; 95% CI 1.39-3.86), blood hemoglobin level (OR 0.76; 95% CI 0.65-0.88), and serum C-reactive protein level (OR 1.27; 95% CI 1.04-1.54). CONCLUSION The cross-sectional analysis using baseline data from the FKR study revealed independent factors associated with hyponatremia in patients with decreased kidney function. Longitudinal analyses of the FKR cohort are needed to evaluate the effects of these factors on the prognosis of hyponatremia in patients with CKD.

Abstract
BACKGROUND Angiotensin II receptor blockers (ARBs) reportedly reduce the risk of developing bone fractures; however, this association remains unclear among patients with chronic kidney disease (CKD). METHODS This was a cross-sectional study of 3380 CKD patients enrolled in the Fukuoka Kidney disease Registry Study, a multicenter prospective observational cohort study of non-dialysis-dependent CKD patients. The patients were divided into two groups, those taking ARBs and those who were not. Logistic regression models were used to examine the association between ARBs and bone fracture. RESULTS Approximately 67.0% of the participants were on ARBs, and 6.3% had a history of bone fracture. The history of bone fracture was significantly lower in patients with prescribed ARB and remained significant even after multivariable adjustment (odds ratio, 0.68; 95% confidence interval, 0.51-0.93). Other antihypertensive drugs, such as thiazide diuretics, which were reportedly helpful in preventing fractures, did not alter the bone fracture history and did not change among ARB users and non-users. CONCLUSIONS The present study showed that administering ARB was significantly associated with a lower frequency of bone fracture history.

Abstract
PURPOSE/OBJECTIVE(S) Whilst standard treatment for intermediate-stage hepatocellular carcinoma (HCC) is transcatheter arterial chemoembolization (TACE), those exceeding "up-to-seven" criteria don't respond as such as those within, and systemic therapy is suggested to be more beneficial. This is sought to be both because of the limited efficacy of TACE and its hepatic toxicity. Proton beam therapy (PBT) offers high local control and low toxicity rates, and we hypothesize that the same can be said in this patient group also. We here present the outcome of PBT for primary HCC exceeding "up-to-seven" criteria. MATERIALS/METHODS Primary HCC treated with PBT between 2010 and 2018 were extracted from an all-in treatment database and retrospectively reviewed. (Maximum diameter of the largest tumor in centimeters) + (tumor count) > 7 was considered as exceeding "up-to-seven" criteria. Local recurrence was defined as tumor re-enlargement or the appearance of arterial phase hyperenhancement. Adverse events were evaluated by CTCAE v5.0. Overall survival and recurrence-free survival were determined by the Kaplan-Meier method, and local recurrence was analyzed as cumulative incidence with death as a competing risk. All statistical analyses were done using R. RESULTS Out of 202 primary cases, 79 exceeded the "up-to-seven" criteria. The median tumor diameter was 8.0 cm (range 3.1 - 20 cm) and macroscopic vascular invasion (MVI) was observed in 26 cases. For tumor count, 36 were solitary, 28 were between 2 - 3, and 15 had 4 or more. According to the modified ALBI grade, 38 were grade 1, 18 were grade 2a and 23 were 2b. The prescribed dose was 66 Gy / 10 Fr for 6, 72.6 Gy / 22 Fr for 60, 74 Gy / 37 Fr for 12 and 60 Gy / 15 Fr for one case after relative biological effect weighting of 1.1. With a median follow-up period of 33 months (IQR 15 - 57 months), 2-year overall survival was 62% (95% C.I. 50 - 72%) and median survival time was 37 months (95% C.I. 30 - 52 months). 2-year recurrence-free survival and local recurrence rate were 42% (95% C.I. 30 - 53%) and 8% (95% C.I. 3 - 15%) respectively. Cox regression analysis revealed modified ALBI grade as the only significant risk factor for survival (hazard ratio 1.80, 95% C.I. 1.27 - 2.55, p = 0.0010) among age, sex, alpha-fetoprotein level, MVI, tumor count, and size. Other than one case of early death (2 weeks after treatment) with an unknown causal relationship, there were no adverse events of grade 4 or higher observed. CONCLUSION PBT for primary HCC exceeding "up-to-seven" criteria appears to be safe and effective. Local control of intrahepatic lesions may be beneficial even in intermediate-stage cases, while results of this study suggests that suppression of out-of-field recurrence is required for further survival prolongment.

Abstract
PURPOSE/OBJECTIVE(S) Vulnerable patients receive a low-intensity, palliative treatment rather than the standard treatment. Defining vulnerability in terms of standard or reduced radiation intensity can result in appropriate radiotherapy for elderly cancer patients without excessive adverse events and poor outcomes. However, it is difficult to define vulnerability, because radiation oncologists hesitate to include vulnerable patients in clinical trials involving radical radiotherapy. We hypothesized that for elderly cancer patients without metastasis, vulnerability scores, obtained by geriatric assessment (GA), could help in predicting the reduction in radiation intensity determined by radiation oncologists based on their experience. MATERIALS/METHODS In this multicenter prospective study, we enrolled cancer patients (70 years or older) without metastasis. The reduction in radiation intensity was categorized into 3 groups as follows: i) standard schedule of radiotherapy, but conversion of irradiation fields, ii) standard irradiation fields, but converted schedule of radiotherapy, and iii) conversion of radiotherapy schedule and irradiation fields. Standard radiotherapy was defined as recommended doses and radiation fields according to the guidelines for the primary tumors analyzed. GA was performed by calculating geriatric 8 (G8) and vulnerable elders survey (VES-13) scores before radiotherapy and 3-5 and 8-16 weeks after completion of radiotherapy. The primary endpoint was to evaluate the correlation between vulnerability assessed by G8 and change in radiation intensity. RESULTS Between November 2020 and February 2022, 317 patients were included in this study at 13 centers in Japan. The median age was 77 (range, 70-90) years. The primary cancer sites were head and neck, esophagus, lungs, breasts, pancreas, bladder, uterus, and prostate in 63, 22, 62, 48, 6, 5, 26, and 85 patients, respectively. High-precision radiotherapy was performed for 199 patients (63%). Of the 31 patients (10%) whose radiation intensity was reduced, 14, 9, and 8 patients were provided i, ii, and iii category, respectively. Planned radiotherapy was completed for 312 patients (98%). G8 and VES-13 vulnerability scores were obtained for 201 and 61 patients, respectively, before radiotherapy. The mean G8 and VES-13 scores were 13.3 ± 2.4 and 1.8 ± 1.8, 12.9 ± 2.6 and 2.0 ± 2.0, and 13.4 ± 2.4 and 2.0 ± 1.9 before radiotherapy and 3-5 and 8-16 weeks after completion of radiotherapy, respectively. Multivariate analysis revealed that reduction in radiation intensity was significantly associated with vulnerability assessed using VES-13 (p < 0.001) but not G8 (p = 0.06). CONCLUSION An excellent completion rate was obtained for planned radiotherapy, and vulnerability assessed using VES-13, not G8, was associated with the reduction in intensity of radiotherapy.

Abstract
PURPOSE/OBJECTIVE(S) Transcatheter arterial chemoembolization (TACE) is the standard treatment for early to intermediate-stage hepatocellular carcinoma (HCC) unfit for hepatectomy or radiofrequency/microwave ablation (RFA/MWA). Putting aside its hepatic toxicity, local control of TACE is far from satisfactory, especially with non- "simple nodular type" appearances, to an extent where systemic therapy is suggested to be more beneficial. We here analyzed the outcome of proton beam therapy (PBT) for primary HCC by macroscopic classification. MATERIALS/METHODS Primary HCC treated with PBT between 2010 and 2018 were extracted from an all-in treatment database. The macroscopic classification was defined by CT or MRI prior to PBT. Local recurrence was defined as tumor re-enlargement or the appearance of arterial phase hyperenhancement. Adverse events were evaluated by CTCAE v5.0. Overall survival, local control, intrahepatic recurrence-free survival, and extrahepatic recurrence-free survival were determined by the Kaplan-Meier method, and the association with treatment factors was analyzed by log-rank and cox regression model. RESULTS A total of 202 primary HCC cases were extracted, all not a candidate for hepatectomy nor RFA/MWA. Out of them, 75 cases were simple nodular type, 79 were simple nodular type with extranodular growth, 38 were confluent multinodular type, and 10 were infiltrative type. 26 cases were HBV positive, and 84 cases were HCV positive. 35 cases had macroscopic vascular invasion (MVI). With a median follow-up period of 3.72 years (IQR: 1.79-5.85years), the 3-year overall survival rate was 68.1% (95% CI 61.0 - 74.3%), the 3-year local control rate was 89.6% (95% CI 83.4-93.5), the 3-year intrahepatic recurrence-free survival rate was 53.7% (95% CI 45.9-60.8%), and the 3-year extrahepatic recurrence-free survival rate was 87.4% (95% CI: 81.5-91.6%). Simple nodular type had better overall survival (73.2% vs 65.2% p = 0.012) and extrahepatic recurrence free survival (96.9% vs 81.9% p<0.01), but there was no statistically significant difference in local control (92.7% vs 87.6% p = 0.06) and intrahepatic recurrence-free survival (62.0% vs 48.5% p = 0.114). Multivariate analysis of risk factors against OS, including age, sex, AFP, MVI, and macroscopic classification, revealed age and macroscopic classification as independent risk factors. Adverse events of grade 3 included 2 cases of gastrointestinal bleeding, 7 cases of liver function disorder, 1 cases of biliary hemorrhage, and 1 case of pleural effusion. Other than one case of early death (2 weeks after treatment) with an unknown causal relationship, there were no adverse events of grade 4 or severe. CONCLUSION PBT for non- "simple nodular type" primary HCC appears to be safe and effective, whilst suppression of out-of-field recurrence is needed for further survival prolongment.

Abstract
Background This multicenter prospective observational study examined the impact of additionally using a home electrocardiograph (ECG) to detect atrial fibrillation (AF) recurrence after ablation. Methods Between May 2019 and December 2020, 128 patients undergoing ablation were enrolled in the study. After performing ablation, they were instructed to measure their ECGs at home using Complete (ECG paired with a blood pressure monitor; Omron Healthcare, Japan) every day and to visit the hospital every 3 months until after 12 months for 24-hour Holter ECG and 12-lead ECG as usual care (UC). Results After ablation, 94 patients were followed up, and AF recurrence at 12 months was detected more commonly in adjudicators-interpreted Complete (31 [33 %]) than in UC (18 [9 %]) (hazard ratio 1.95, 95 % confidence interval [95 %CI] 1.35-2.81, P < 0.001). In patients with recurrent AF found via both modalities (n = 16), the time to first AF detection by Complete was 40.9 ± 73.9 days faster than that in UC (P = 0.04). Notably, when the adherence to Complete measurement was divided by 80 %, the add-on effect of Complete on the detection of recurrent AF in UC indicated the hazard ratio (HR) of 1.71 (95 %CI 0.92-3.18, P = 0.09) for the low adherence (<80 %) group, but it was significant for the high adherence (≥80 %) group, with HR of 2.19 (95 %CI 1.43-3.36, P < 0.001). Conclusions Despite a shorter measurement time, Complete detected recurrent AF more frequently and faster compared with UC after AF ablation. A significant adherence-dependent difference of Complete was found in detecting AF recurrence.

Abstract
AIM To clarify the usefulness and accuracy of segmental adrenal venous sampling (sAVS) on localisation and functional diagnosis of various adrenal lesions in primary aldosteronism. MATERIALS AND METHODS Consecutive patients (n=162) who underwent adrenalectomy and 138 patients indicated for medication following sAVS were analysed retrospectively. Based on immunohistopathological diagnosis, the positive predictive value (PPV) of computed tomography (CT)-detectable aldosterone-producing adenoma (APA) was calculated. Moreover, endocrinological and sAVS characteristics were analysed quantitatively and qualitatively among APA, CT-undetectable aldosterone-producing nodules (APNs), multiple aldosterone-producing micronodules (MAPM), and medication groups. RESULTS The PPV of APA by sAVS was 137/141 (97.1%; 95% confidence interval, 92.9-99.2%). Compared to the medication cases, the APA group showed stronger disease activity clinically and significant differences in adrenal hormones, such as a higher aldosterone level and aldosterone-to-cortisol ratio, and lower cortisol levels in the adrenal central vein and aldosterone maximum tributaries on the dominant side after cosyntropin stimulation. The APA group shows focal aldosterone hypersecretion, such as mean number of aldosterone elevated segments (1.7 ± 0.7 versus 2 ± 0.9, p=0.003) and presence of aldosterone-not-elevated segments (93% versus 41%, p<0.001). Clinically and in terms of sAVS, APN and MAPM showed similar characteristics to APA and to the medication cases, respectively. CONCLUSION sAVS can localise functionally active tissues of CT-detectable and CT-undetectable lesions enabling decisions on surgical or medical treatment.

Abstract
AIM Acute kidney injury (AKI) is an important clinical issue in the diagnosis and treatment of cardiovascular diseases. The association between pretreatment by statins and the occurrence of AKI in patients with peripheral arterial diseases (PAD) remains unclear. Therefore, we examined the association between statin therapy and the occurrence of AKI in patients with PAD. METHODS We retrospectively analyzed data from the endovascular treatment (EVT) database in our hospital. A total of 295 patients who underwent angiography and/or intervention for PAD between October 2011 and March 2016 were enrolled and divided into two groups: those without statins (control group; N=157) and those with statins (statin group; N=138) for at least 1 month before admission. We examined the occurrence of AKI and its related factors in these patients. RESULTS The serum creatinine levels, dose of contrast medium, use of a renin-angiotensin system inhibitor, smoking habit, and blood pressure were similar in both groups. The statin group had more diabetes patients, had patients who were significantly younger, had patients with a higher body mass index (BMI), and had patients with lower low-density lipoprotein cholesterol than the control group. With regard to the occurrence of AKI, there was a significantly lower incidence in the statin group compared with the control group (5% vs. 16%, p<0.05). The result of the multivariate analysis indicated that statin therapy was significantly correlated with lower occurrence rates of AKI (p<0.05). CONCLUSIONS Our study suggests that statin therapy might prevent the occurrence of AKI after angiography and/or intervention for PAD.

Abstract
Introduction
Patients with chronic kidney disease often suffer from cardiovascular disease, and vascular calcification has been identified as one of the risk factors for cardiovascular disease. We aimed to examine the effect of dialysis treatment before kidney transplantation on graft survival, vascular calcification, and its progression after kidney transplantation.
Methods
Among the 102 patients who underwent kidney transplant between 2008 and 2017, two patients were excluded for moved and lost to follow-up and primary nonfunction. The clinical characteristics and laboratory data were assessed according to pretransplant treatment modality. Rapid progression of vascular calcification was defined when patients showed an increase in the highest tertile of progression of each iliac artery calcification thickness (IACT) and aortic calcification index (ACI).
Results
Cox proportional hazard models did not show any significant association between pretransplant treatment modality and graft survival to the doubling of creatinine from nadir creatinine during the first 3 months after kidney transplantation. At baseline, the IACT was significantly higher in hemodialysis patients than in preemptive kidney transplant patients, whereas the ACI was comparable among the pretransplant treatment modality groups. IACT was independently associated with dialysis vintage. There was no significant association between rapid progression of vascular calcification (IACT and ACI) and dialysis modality.
Conclusions
Dialysis modality was an independent factor related to IACT, whereas there was no legacy effect for the progression of vascular calcification after kidney transplantation.

Abstract
AbstractThis paper reports the results of an international interlaboratory study led by the National Institute of Standards and Technology (NIST) on the measurement of high-pressure surface excess methane adsorption isotherms on NIST Reference Material RM 8850 (Zeolite Y), at 25 °C up to 7.5 MPa. Twenty laboratories participated in the study and contributed over one-hundred adsorption isotherms of methane on Zeolite Y. From these data, an empirical reference equation was determined, along with a 95% uncertainty interval (Uk=2). By requiring participants to replicate a high-pressure reference isotherm for carbon dioxide adsorption on NIST Reference Material RM 8852 (ZSM-5), this interlaboratory study also demonstrated the usefulness of reference isotherms in evaluating the performance of high-pressure adsorption experiments.

Abstract
Lithium-induced nephrogenic diabetes insipidus (NDI) is a rare and difficult-to-treat condition. We describe the case of an 81-year-old woman with bipolar treated with lithium and no previous history of diabetes insipidus. She was hospitalized due to disturbance of consciousness and was diagnosed with, hypercalcemia, hyperparathyroidism, and NDI. Parathyroidectomy was contraindicated and parathyroid hormone level was improved insufficiently after cinacalcet initiation, percutaneous ethanol injection therapy was performed for the enlarged parathyroid gland. After improvement in hypercalcemia and unsuccessful indapamide treatment, triamterene was administrated to control polyuria. Lithium is one of the indispensable maintenance treatment options for bipolar disorder, but it has the side effect of NDI. Lithium enters the collecting duct's principal cells mainly via the epithelial sodium channel (ENaC) located on their apical membranes, ENaC shows high selectivity for both sodium and lithium, is upregulated by aldosterone, and inhibited by triamterene. To our knowledge, this is the first publication on triamterene use in lithium-induced NDI patients.

Abstract
INTRODUCTION When performing linear ablation, creating contiguous and transmural lesions are technically challenging due to the difficulty in finding electrical conduction gaps. We hypothesized that high-density mapping could identify the gaps. METHODS AND RESULTS This study included consecutive patients who underwent conduction gap mapping of de novo lesions (41 patients, 55 lines) and previous lesions (25 patients, 34 lines). We analyzed the utility of bipolar and unipolar conduction gap mapping and retrospectively assessed the voltage and morphology of the bipolar electrograms at the gap sites. Bipolar and unipolar propagation maps were classified into three types: the propagation wavefront traveled through the linear ablation lesions (direct leak), the wavefront jumped to an opposite site across the line and returned to the line (jump and return leak), and others (indefinite leak). In the jump and return leak maps, the site where it returned suggested a conduction gap site. Bipolar propagation maps identified 30 (54.5%) conduction gaps and unipolar maps identified 40 (72.7%) gaps at de novo linear ablation lesions (P = .01), and 32 (94.1%) gaps and 33 (97.1%) gaps, respectively, at previous lesions (P = .56). Bipolar voltage mapping did not add any further efficacy in detecting conduction gaps, and the morphology of the electrograms recorded at the gap sites was not related to the types of propagation maps. CONCLUSION Conduction gaps of linear ablation lesions can be visualized by high-density mapping with a high probability. Unipolar propagation, when used with bipolar mapping, may help detect conduction gap sites.

Abstract
Abstract
Background and Aims
Vascular calcification is a risk factor for cardiovascular disease and mortality in dialysis and transplant patients. Previous studies have shown that coronary artery calcification correlates with cardiovascular mortality. However, it is not known whether vascular calcification of the abdominal aorta and common iliac artery (CIA) may impact clinical outcomes after kidney transplantation. The aim of this study was to identify the risk factors of vascular calcification after kidney transplantation.
Method
In this retrospective study, we assessed 100 patients who underwent kidney transplantation between 2008 and 2017. Of these, 62 patients received a computed tomography (CT) scan of the abdomen twice with an interval of at least 6 months. We examined the characteristics of vascular calcification of the abdominal aorta and iliac artery and divided the patients into three groups based on dialysis modality before transplantation: hemodialysis (HD group), peritoneal dialysis (PD group) and preemptive kidney transplantation (PEKT group). Then, we identified the risk factors for the progression of calcification. Abdominal aortic calcification was assessed based on the aortic calcification index (ACI), and calcification of CIA was assessed based on the maximal thickness of calcification.
Results
At baseline, abdominal aortic calcification was present in 66% of patients, and the median ACI was 10 [0-30]. Calcification of the CIA was present in 62% of patients, and maximal thickness of the CIA was 2.4 mm [0-4.6]. The mean duration of follow-up was 68 ± 29 months, and the mean interval of CT was 40 ± 29 months. After kidney transplantation, the progression rate of ACI and maximal thickness of CIA were 1.6 ± 2.5 per year and 0.17 ± 0.41 mm per year, respectively. The maximal thickness of CIA calcification was significantly higher, and ACI tended to be higher in the HD group than in the PEKT group. Age, male gender, diabetes mellitus and dialysis vintage were the independent variables related to both ACI and maximal thickness of CIA calcification. The progression rates of ACI and maximal thickness of CIA were comparable among the three groups in terms of dialysis modality. Age and rejection within the first 6 months were independent risk factors for ACI progression, and diabetes mellitus was an independent risk factor for progression of maximal thickness of CIA. No significant association was found between the progression of vascular calcification and dialysis-related parameters, including dialysis modality and vintage.
Conclusion
This study suggests that dialysis vintage was the independent variable related to calcification of the abdominal aorta and common iliac artery, whereas dialysis modality was not a significant predictor of vascular calcification and its progression in these blood vessels.

Abstract
Background:
Hypertension in patients with atrial fibrillation (AF) is a known independent risk factor for stroke. The Complete blood pressure (BP) monitor (Omron Healthcare, Kyoto, Japan) was developed as the first BP monitor with electrocardiogram (ECG) capability in a single device to simultaneously monitor ECG and BP readings. This study investigated whether the Complete can accurately differentiate sinus rhythm (SR) from AF during BP measurement. Methods and Results:
Fifty-six consecutive patients with persistent AF admitted for catheter ablation were enrolled in the study (mean age 65.8 years; 83.9% male). In all patients, 12-lead ECGs and simultaneous Complete recordings were acquired before and after ablation. The Complete interpretations were compared with physician-reviewed ECGs, whereas Complete recordings were reviewed by cardiologists in a blinded manner and compared with ECG interpretations. Sensitivity, specificity, and κ coefficient were also determined. In all, 164 Complete and ECG recordings were simultaneously acquired from the 56 patients. After excluding unclassified recordings, the Complete automated algorithm performed well, with 100% sensitivity, 86% specificity, and a κ coefficient of 0.87 compared with physician-interpreted ECGs. Physician-interpreted Complete recordings performed well, with 99% sensitivity, 85% specificity, and a κ coefficient of 0.85 compared with physician-interpreted ECGs. Conclusions:
The Complete, which combines BP and ECG monitoring, can accurately differentiate SR from AF during BP measurement.

Abstract
Background: Oily fish and their extracted oils may be a source of polychlorinated biphenyls (PCBs) which can induce toxic effects on the consumers. The main aim of this survey was estimation of PCBs intake through fish oil-derived dietary supplements and prescription drugs in the Japanese population. Methods: PCBs levels were determined in 20 fish oil-derived dietary supplements and 6 oil-derived prescription drugs from the Japanese market using Gas Chromatography-Mass Spectrometry. Then, the daily exposure to PCBs was estimated. Data were statistically analyzed using JMP software suite. Results: Totally, 17 of the 26 fish oil-derived products were contaminated with PCBs. The median PCB concentrations in the total set of fish oil-derived products was 2.2 ng/g oil wt. with a range of <MDL-720 ng/g oil wt. The average total daily intake of PCBs was estimated to be ranged from 770 to 2800 ng/day in the Japanese population. Conclusion: PCBs intakes through fish oil-derived dietary supplements and prescription drugs in the Japanese adults were much lower than tolerable daily intake

Abstract
INTRODUCTION Many reports show that denture adhesives improve the retention and stability of dentures. However, few randomized controlled trials have examined the effects of denture adhesives. OBJECTIVE This 10-center randomized controlled trial with parallel groups involving 200 edentulous patients wearing complete dentures aimed to evaluate the effects of short-term use of cream and powder denture adhesives. METHODS Patients were allocated into 2 cream- and powder-type adhesive groups and 1 control group. Intervention groups were treated with the 2 adhesives (1 each), and the control group received saline solution. Adhesive or control was applied to the denture-mucosal surface for 4 d, and data at baseline and after day 4 of intervention (i.e., 8 meals) were obtained. Patient satisfaction was evaluated with a 100-mm visual analog scale. Oral health-related quality of life was measured with the Japanese version of the Oral Health Impact Profile for Edentulous Patients. Perceived chewing ability was evaluated by a questionnaire regarding ease of chewing and swallowing food. Between-group comparisons were performed with Kruskal-Wallis tests with the Mann-Whitney U test adjusted by Bonferroni correction. Within-group comparisons of pre- and postintervention measurements were performed with the Wilcoxon signed-rank test. Intention-to-treat analysis was also performed. RESULTS Between-group comparisons showed no significant differences for general satisfaction or Oral Health Impact Profile for Edentulous Patients. However, significant differences in satisfaction with various denture functions with cream- and powder-type adhesives were seen in pre- and postintervention comparisons (P < 0.05). Significant differences were also observed for perceived chewing ability of hard foods (P < 0.05). CONCLUSION These results suggest that although denture adhesives do not invariably improve denture function, they do affect subjective evaluations and possibly chewing of hard foods. Therefore, the effects of denture adhesive use are insufficient to resolve any fundamental dissatisfaction with dentures ( ClinicalTrials.gov NCT01712802 ). KNOWLEDGE TRANSFER STATEMENT The results of this study suggest that denture adhesives should be applied under certain conditions; however, an appropriate diagnosis is important before application. These practice-based data provide information to establish evidence-based guidelines for applying denture adhesives.

Abstract
This paper reports the results of an international interlaboratory study led by the National Institute of Standards and Technology (NIST) on the measurement of high-pressure surface excess carbon dioxide adsorption isotherms on NIST Reference Material RM 8852 (ammonium ZSM-5 zeolite), at 293.15 K (20 °C) from 1 kPa up to 4.5 MPa. Eleven laboratories participated in this exercise and, for the first time, high-pressure adsorption reference data are reported using a reference material. An empirical reference equationn e x = d ( 1 + exp [ - ln ( P ) + a / b ] ) c , [n ex -surface excess uptake (mmol/g), P-equilibrium pressure (MPa), a = -6.22, b = 1.97, c = 4.73, and d = 3.87] along with the 95% uncertainty interval (U k = 2 = 0.075 mmol/g) were determined for the reference isotherm using a Bayesian, Markov Chain Monte Carlo method. Together, this zeolitic reference material and the associated adsorption data provide a means for laboratories to test and validate high-pressure adsorption equipment and measurements. Recommendations are provided for measuring reliable high-pressure adsorption isotherms using this material, including activation procedures, data processing methods to determine surface excess uptake, and the appropriate equation of state to be used.

Abstract
Acellular hemoglobin (Hb) derivates developed as oxygen carriers are known to cause hypertensive reactions due to their nitric oxide (NO) scavenging action. To modulate this undesired activity, we have developed a new Hb derivative, s-nitrosylated polyethylene glycol (PEG)-modified hemoglobin (SNO-PEG-Hb), which can deliver oxygen and NO. After human Hb was modified with PEG to increase its molecular weight, the free sulfhydryl groups of Hb were s-nitrosylated with s-nitrosoglutathione. Administration of unmodified Hb into anesthetized rats caused a hypertensive reaction, while s-nitrosylated Hb derivatives such as SNO-Hb and SNO-PEG-Hb did not raise blood pressure. The plasma half-lives of heme and NO bound to SNO-PEG-Hb were 11.5 and 2.4 hours respectively, indicating that the s-nitrosylated Hb derivative may act as a slow-releasing agent for NO. Based on these findings, SNO-PEG-Hb is a useful candidate for a blood substitute and tool for oxygen therapeutics.

Abstract
It is known that calcium-containing phosphate binders are more closely associated with the progression of vascular calcification than non-calcium-containing phosphate binders. In this study, we investigated the effect of the non-calcium-containing phosphate binder, lanthanum carbonate on the progression of coronary artery calcification and cardiovascular abnormalities compared to that of calcium-containing phosphate binder in chronic kidney disease patients during the early period after initiating hemodialysis. This was a randomized open-label study in which patients were divided into the calcium carbonate or lanthanum carbonate group. We evaluated blood samples, coronary artery calcification using high-resolution computed tomography, and cardiac abnormalities using echocardiography prior to and after initiating hemodialysis. Cardiac dimension and systolic function were significantly improved in the lanthanum carbonate group compared to those in the calcium carbonate group. Although statistically significant differences were not observed in all the patients, only among patients with moderate coronary artery calcification, the changes in coronary artery calcification score at 18 months were significantly smaller in the lanthanum carbonate group than those in the calcium carbonate group. The percent change in coronary artery calcification at 18 months was significantly correlated with the serum fibroblast growth factor 23 levels at 18 months (r = 0.245, P < 0.05). This significant correlation was particularly strong in patients with moderate coronary artery calcification (r = 0.593, P < 0.001). Our study suggests that lanthanum carbonate ameliorates cardiac abnormalities, and may slow coronary artery calcification development in patients with moderate coronary artery calcification, during the early period following hemodialysis initiation.

Abstract
Aim: Chronic kidney disease–mineral bone disorder (CKD–MBD) is associated with all-cause and cardiovascular morbidity and mortality in patients with CKD. Thus, elucidating its pathophysiological mechanisms is essential for improving the prognosis. We evaluated characteristics of CKD–MBD in a newly developed CKD rat model. Methods: We used male Sprague–Dawley (SD) rats and spontaneously diabetic Torii (SDT) rats, which are used as models for nonobese type 2 diabetes. CKD was induced by 5/6 nephrectomy (Nx). At 10 weeks, the rats were classified into six groups and administered with a vehicle or a low- or high-dose paricalcitol thrice a week. At 20 weeks, the rats were sacrificed; blood and urinary biochemical analyses and histological analysis of the aorta were performed. Results: At 20 weeks, hemoglobin A1c (HbA1c) levels, blood pressure, and renal function were not significantly different among the six groups. Serum calcium and phosphate levels tended to be higher in SDT-Nx rats than in SD-Nx rats. The urinary excretion of calcium and phosphate was significantly greater in SDT-Nx rats than in SD-Nx rats. After administering paricalcitol, serum parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF23) levels were significantly higher in SDT-Nx rats than in SD-Nx rats. The degree of aortic calcification was significantly more severe and the aortic calcium content was significantly greater in SDT-Nx rats than in SD-Nx rats. Conclusions: We suggest that our new CKD rat model using SDT rats represents a useful CKD–MBD model, and this model was greatly influenced by paricalcitol administration. Further studies are needed to clarify the detailed mechanisms underlying this model.

Abstract
Herein, we report a case of fibrillary glomerulonephritis (FGN). FGN usually shows non-amyloidal fibrils in the mesangium and glomerular capillary walls on electron microscopy. Inherited cases of FGN have been reported in only 3 families, and the suspected genetic form was autosomal dominant. In the present case, the deposition of microfibrils in the arteriolar wall as well as the glomerulus is unique. Our patient's father died of nephrotic syndrome, and his elder brother had a biopsy-proven glomerulopathy. The histological findings of the brothers are similar to mesangial proliferative glomerulonephritis and resemble each other. Therefore, our case is presumed to be familial FGN. Additionally, herein, we review the literature and reconsider the histological and clinical characters of FGN.

Abstract
When using vitamin D, the most important clinical problems are hypercalcemia, hyperphosphatemia, and vascular calcification. VS-105 is a novel vitamin D receptor (VDR) analog. In the present study, we compared the effects of VS-105 and paricalcitol on chronic kidney disease-mineral bone disorder (CKD-MBD) in a CKD rat model. We used male Sprague-Dawley (SD) rats and performed 5/6 nephrectomy at 8-9 weeks. At 10 weeks, the rats were classified into five groups and administered vehicle, low-dose paricalcitol (LP, 0.1μg/kg), high-dose paricalcitol (HP, 0.3μg/kg), low-dose VS-105 (LV, 0.2μg/kg), and high-dose VS-105 (HV, 0.6 μg/kg) three times a week for 10 weeks. There were no significant differences in blood pressure or renal function among the five groups. Alhough serum calcium levels were comparable between the LP and LV groups, they were higher in the HP group than in the HV group. Serum phosphate levels were higher in the paricalcitol-treated groups than in the VS-105-treated groups and paticularly higher in the HP group than in the other groups. The urinary excretion of phosphate was greater in the VS-105-treated groups than in the paricalcitol-treated groups. Serum parathyroid hormone (PTH) levels decreased and serum fibroblast growth factor-23 (FGF23) levels were elevated after administering paricalcitol and VS-105; however, serum FGF23 levels were remarkably elevated in the paricalcitol-treated groups. Further biochemical analyses revealed that the calcium content of the aorta was higher in the paricalcitol-treated groups than in the VS-105-treated group. VDR and Klotho expression in the kidney was significantly higher in the VS-105-treated groups than in the paricalcitol-treated groups although both agents increased these expressions. Our data suggest that VS-105 had a lesser effect on CKD-MBD than paricalcitol except in the case of serum PTH levels. The mechanism appears to be associated with the difference in VDR and Klotho expression.

Abstract
Antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis is a life-threatening disease characterized by rapidly progressive glomerulonephritis (RPGN) and diffuse alveolar hemorrhage (DAH). Glucocorticoids and immunosuppressants are commonly used to treat this disease but may induce irreversible side effects, particularly in elderly patients. We herein report the case of a 76-year-old woman with RPGN. After methylprednisolone pulse therapy, DAH occurred, and she required ventilatory support. After plasma exchange, her serum creatinine level improved, and she was discharged with home oxygen therapy. Immunosuppressive agents other than glucocorticoids were not required. In conclusion, plasma exchange with glucocorticoid therapy may be effective in treating severe ANCA-associated vasculitis in elderly patients.

Abstract
Fibroblast growth factor 23 (FGF23) is regulated by sustained phosphate supplementation and restriction. However, few studies have investigated FGF23 levels in patients with Fanconi syndrome. Therefore, we evaluated intact and C-terminal FGF23 and FGF23-associated parameters in four patients with Fanconi syndrome. Serum intact and C-terminal FGF23 levels were extremely low. Although serum phosphate and 1,25-dihydroxyvitamin D levels improved to or above the normal range within 1 year of treatment with oral phosphate and calcitriol, serum FGF23 levels remained low. Serum FGF23 levels in patients with Fanconi syndrome might be regulated by novel factors other than serum phosphate and 1,25-dihydroxyvitamin D levels.

Abstract
OBJECTIVE To investigate the impact of a neutron beam formed with the accelerator-based epithermal neutron source designed at the G.I. Budker Institute of Nuclear Physics (INP) on the viability of human and animal tumor cells cultured in the presence of boron-10 isotope. MATERIAL AND METHODS Human U251 and T98G glioma cells and Chinese hamster CHO-K1 and V-79 cells were incubated at various concentrations in the culture medium containing 10B-enriched L-boronophenylalanine. The cells were irradiated with a neuron beam using the accelerator-based epithermal neuron source. A clonogenic assay was used to evaluate the viability of the irradiated cells. The absorbed doses obtained from elastic scattering of fast neutrons by substance nuclei and the doses obtained from boron neutron capture were calculated using the NMS code. The absorbed doses of gamma-radiation were measured with a mixed radiation dosimeter. RESULTS The viability of boron-containing and intact human U251 and T98G cell lines and Chinese hamster CHO-K1 and V-79 cells was analyzed after neutron beam radiation. Irradiation of all four cell lines were cultured in the presence of 10B was shown to reduce their colony-forming capacity compared with the control. Elevated boron levels in the culture medium resulted in a significant decrease in the proportion of survived cells. Radiation had the most pronounced impact on the proliferative capacity of the human U251 glioma cell lines. CONCLUSION The cultures of human tumor cells and mammalian cells demonstrated that the neutron beam formed with the accelerator-based epithermal neutron source designed at the INP, was effective in reducing the viability of tumor cells in the presence of 10B.

Abstract
Selective estrogen receptor modulators(SERMs)have beneficial effects on the improvement of bone mineral density of the spine and hip, and decrease the vertebral fracture in postmenopausal women. Similar to patients with advanced chronic kidney disease, including dialysis patients, however, SERMs cannot decrease the risk of hip fracture, which is extremely high in Japanese dialysis patients. One of the most important disadvantages of SERMs is an increase in the risk of venous thromboembolic events and fatal stroke in high-risk groups of the Framingham Stroke Risk Score. On the other hand, SERMs may be used in unique osteoporosis drugs for reducing the incidence and progression of breast cancer. Moreover, SERMs attenuate oxidative stress and may lessen the deterioration of kidney function in patients with chronic kidney disease. The evidences for the efficacy and safety of SERMs in patients with advanced chronic kidney disease are insufficient, and knowledge concerning the selection and indication of osteoporosis drugs for those patients need to be developed.

Abstract
Seventy four cases of internal carotid stenoses greater than 60% were treated by PTA and/or stenting 86 times. Sixty one cases of cervical ICA stenosis were treated 71 times. 11 cases of high cervical - intracranial ICA stenosis were treated 13 times. Two cases of ICA dissection were treated by stent deployment. Stenotic ratio reduced from 79% to 29% in cervical ICA stenosis and 71 % to 32% in high cervical to intracranial ICA stenosis in average. Morbidity related to PTA and/or stenting was 2/74 (2.7%) and mortality was 0%. One was an ischemic complication and the other was a hemorrhagic complication due to hyperperfusion. Restenosis (stenosis greater than 70%) rate was 32%. Asymptomatic cerebral embolism were found in three cases (4.2%) on angiogram immediately after PTA and/or stenting. The complication rate related to PTA and/stenting was low but asymptomatic emboli were found in three cases. Considering these results, the indication for PTA and/stenting should be restricted to patients with high risk group, such as cases with high medical risks or difficult CEA cases, if appropriate protective systems for cerebral emboli were not available.
