Abstract
AIMS/INTRODUCTION Healthcare resource utilization (HCRU) and healthcare costs are important factors to consider when selecting appropriate treatment for type 2 diabetes mellitus. We compared the HCRU and healthcare costs of sodium-glucose cotransporter 2 inhibitors (SGLT2i) vs dipeptidyl peptidase-4 inhibitors (DPP4i) in patients with type 2 diabetes mellitus in Japan. MATERIALS AND METHODS This was a Japanese retrospective cohort study conducted using the JMDC Claims Database (January 1, 2015-December 31, 2021). Patients newly treated with an SGLT2i (31,872 patients) or a DPP4i (73,279 patients) were matched 1:1, using propensity score, after excluding patients without continuous SGLT2i or DPP4i prescriptions after the index date. HCRU and healthcare costs were compared between the treatment groups in the full cohort and subcohorts/subgroups of different baseline characteristics, including body mass index (BMI). RESULTS After matching, patient characteristics were well balanced (17,767 patients each). Patients receiving an SGLT2i vs those receiving a DPP4i had significantly lower numbers of hospitalizations per person per month (PPPM) and outpatient visits PPPM, and had shorter lengths of stay per hospitalization. Healthcare costs, including all-cause overall healthcare costs PPPM and all-cause hospitalization costs PPPM, were generally lower in patients receiving an SGLT2i than those receiving a DPP4i. Similar results were observed among patients with a higher BMI but not among patients with a lower BMI. CONCLUSIONS SGLT2i were associated with lower HCRU and healthcare costs than DPP4i, suggesting economic benefits with SGLT2i vs DPP4i in type 2 diabetes mellitus management.

Abstract
AIMS/INTRODUCTION Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have shown beneficial effects on cardiometabolic risk factors (hemoglobin A1c, body mass index, systolic blood pressure) in patients with type 2 diabetes mellitus. We compared combined cardiometabolic effects of SGLT2i on hemoglobin A1c, body mass index and systolic blood pressure versus dipeptidyl peptidase-4 inhibitors (DPP4i) in Japanese patients with type 2 diabetes mellitus. MATERIALS AND METHODS This Japanese retrospective cohort study used the JMDC claims database. Patients newly treated with an SGLT2i (n = 18,936) or DPP4i (n = 55,484) were enrolled (January 2015-March 2020) and matched 1:1 using the propensity score. The primary end-point was the proportion of patients achieving a composite outcome (i.e., simultaneous absolute/percent reduction in hemoglobin A1c ≥0.5%, body mass index ≥3% and systolic blood pressure ≥2 mmHg) 1 year after first SGLT2i or DPP4i prescription; Mantel-Haenszel common risk difference and its 95% confidence interval were estimated. Other end-points included treatment persistence, with the associated hazard ratio calculated using the Cox proportional hazards model. RESULTS After matching, patient characteristics were balanced (7,302 patients each). The proportion of patients achieving the composite outcome was significantly greater in patients receiving an SGLT2i than those receiving a DPP4i (31.0% [1,279/4,120] vs 12.9% [524/4,070], risk difference 18.6%, 95% confidence interval 16.3, 20.9, P < 0.001). Risk of treatment discontinuation was significantly lower in the SGLT2i group than in the DPP4i group (hazard ratio 0.85, 95% confidence interval 0.81, 0.90, P < 0.001). CONCLUSIONS In the present study, SGLT2i showed favorable cardiometabolic risk reduction and longer treatment persistence than DPP4i in Japanese patients with type 2 diabetes mellitus.

Abstract
AIMS To investigate the baseline demographic and clinical characteristics of patients with type 1 diabetes mellitus (T1DM) newly treated with a sodium-glucose cotransporter 2 inhibitor (SGLT2i) as an add-on to insulin, or treated with insulin alone or in combination with oral anti-diabetic drugs other than an SGLT2i. METHODS Retrospective study using data from the JMDC database (December 21, 2018, to October 31, 2020). Included patients with T1DM treated with an SGLT2i (add-on to insulin) (n = 1027) or with insulin (n = 4320). Baseline demographic and clinical characteristics were summarized, and change in insulin dose and efficacy outcomes, including hemoglobin A1c (HbA1c) and body mass index (BMI), before and after the first SGLT2i or insulin prescription were evaluated. RESULTS The SGLT2i add-on group had higher HbA1c and BMI than the insulin group. Daily insulin doses decreased from immediately before to after the first SGLT2i prescription. HbA1c and BMI improved from baseline to after the first SGLT2i prescription. CONCLUSIONS This large real-world study reported the baseline demographic and clinical characteristics of patients with T1DM newly treated with an SGLT2i in Japan. The findings may guide the appropriate use of SGLT2i and support large-scale database studies in T1DM research.

Abstract
AIMS/INTRODUCTION To evaluate the benefit of sodium-glucose cotransporter 2 inhibitors (SGLT2i) versus dipeptidyl peptidase-4 inhibitors (DPP4i) in reducing cardiovascular disease (CVD) events in patients with type 2 diabetes mellitus (T2DM) with and without a CVD history. MATERIALS AND METHODS This retrospective cohort study used Japanese hospital administrative data from the Medical Data Vision database (January 2015 to April 2020). Patients with T2DM (N=625,739) who were new users of an SGLT2i (N=57,070; 9.1%) or DPP4i (N=568,669; 90.9%) were included. Outcomes included hospitalization for heart failure (hHF), all-cause death (ACD), and the composite of hHF or ACD. Hazard ratios (HR) were calculated using the inverse probability weighting Cox proportional hazards model to compare CVD event risks between treatment groups. RESULTS Compared with DPP4i, SGLT2i was associated with a significant reduction in hHF risk among patients without a CVD history (HR 0.507, 95% confidence interval [CI] 0.283-0.907), but not in the full cohort or those with a CVD history. SGLT2i was associated with a significant risk reduction of ACD (HR 0.592, 95% CI 0.481-0.729), and the composite of hHF or ACD (HR 0.712, 95% CI 0.613-0.826), compared with DPP4i in the full cohort; similar results were observed among patients with and without a CVD history. CONCLUSIONS In this real-world study, SGLT2i versus DPP4i was associated with a significant reduction in hHF, ACD, and hHF or ACD events, in patients with T2DM without a CVD history.

Abstract
In this study, hydrogen boride films are fabricated by ion-exchange treatment on magnesium diboride (MgB2) films under ambient temperature and pressure. We prepared oriented MgB2 films on strontium titanate (SrTiO3) substrates using pulsed laser deposition (PLD). Subsequently, these films were treated with ion exchangers in acetonitrile solution. TOF-SIMS analysis evidenced that hydrogen species were introduced into the MgB2 films by using two types of ion exchangers: proton exchange resin and formic acid. According to the HAXPES analysis, negatively charged boron species were preserved in the films after the ion-exchange treatment. In addition, the FT-IR analysis suggested that B-H bonds were formed in the MgB2 films following the ion-exchange treatment. The ion-exchange treatment using formic acid was more efficient compared to the resin treatment; with respect to the amount of hydrogen species introduced into the MgB2 films. These ion-exchanged films exhibited photoinduced hydrogen release as observed in a powder sample. Based on the present study, we expect to be able to control the morphology and hydrogen content of hydrogen boride thin films by optimising the ion-exchange treatment process, which will be useful for further studies and device applications.

Abstract
BACKGROUND Chronic constipation (CC) is associated with lower health-related quality of life (HR-QoL) and work productivity in Western countries;however, limited data in Japanese subjects are available. METHODS This retrospective, cross-sectional analysis used the data from the National Health and Wellness Survey (NHWS), a web-based questionnaire survey conducted in 2017 for the Japanese general population. Subjects were allocated to the self-reported CC group when they answered "yes" to the question "Did you have chronic constipation in the past 12 months?". Other subjects were allocated to the non-CC group. Self-reported CC population was sub-categorized as per the abdominal symptoms. The HR-QoL was assessed using the Medical Outcomes Study 12-Item Short-Form Health Survey version 2 using the Mental Component Summary (MCS), Physical Component Summary (PCS), and Role/Social Component Summary (RCS) scores (3-component method). Work productivity was assessed using the Work Productivity and Activity Impairment:General Health version 2.0 for absenteeism, presenteeism, work productivity loss, and activity impairment. RESULTS Of the 30001 respondents, 3373 had self-reported CC (895 with abdominal symptoms, 2478 without abdominal symptoms) and 26628 did not report CC. The differences in the summary scores [95% confidence interval (CI) ] adjusted for potential confounders between self-reported CC and non-CC (self-reported CC - non-CC) were -1.60 (-1.98, -1.22) in MCS, -0.78 (-1.19, -0.37) in PCS, and -2.09 (-2.57, -1.61) in RCS;the differences in the adjusted summary scores (95% CI) between self-reported CC with and without abdominal symptoms (self-reported CC with abdominal symptoms - without abdominal symptoms) were -0.95 (-1.77, -0.14) in MCS, -1.67 (-2.66, -0.68) in PCS, and -2.05 (-3.55, -0.55) in RCS. All the summary scores were lower in those with self-reported CC and abdominal symptoms than in those with self-reported CC without abdominal symptoms;all the adjusted differences between the summary scores were statistically significant. The adjusted risk ratio (95% CI) of each outcome of self-reported CC relative to non-CC was 1.34 (1.04, 1.73) in absenteeism, 1.21 (1.12, 1.31) in presenteeism, 1.20 (1.11, 1.29) in work productivity loss, and 1.21 (1.15, 1.27) in activity impairment. In terms of statistics, the risk of decreased work productivity for all the outcomes was significantly higher in those with than in those without self-reported CC, indicating decreased work productivity in those with self-reported CC. CONCLUSION HR-QoL and work productivity were lower in those with self-reported CC than in those who did not report CC, suggesting that CC negatively affects the HR-QoL and work productivity.

Abstract
We conducted a systematic review of the literature and network meta-analysis (NMA) to compare the relative effectiveness of antibiotic treatments for Clostridioides (Clostridium) difficile infection (CDI) including vancomycin (VCM), metronidazole (MTZ) and fidaxomicin (FDX). Eligible studies were randomised controlled trials (RCTs) including adults with any severity of CDI that was treated with VCM, MTZ or FDX. The NMA was performed using a Bayesian framework, using a fixed-effects model. The searches identified seven publications for inclusion, which provided five RCTs for VCM versus MTZ, and three RCTs for FDX versus VCM. The NMA showed that for clinical cure rate, there was no difference for FDX versus VCM, and there was a significant difference in favour of FDX versus MTZ (odds ratio [OR]: 1.77; 95% credible interval [CrI] 1.11, 2.83]). For recurrence rate, there was a significant difference in favour of FDX versus both VCM (OR: 0.50; 95% CrI: 0.37, 0.68) and MTZ (OR: 0.44; 95% CrI: 0.27, 0.72). For sustained cure (clinical cure without recurrence), there was a significant difference in favour of FDX versus VCM (OR: 1.61; 95% CrI: 1.27, 2.05) and MTZ (OR: 2.39; 95% CrI: 1.65, 3.47). These findings suggest that FDX and VCM are effective first-line treatments for mild or moderate CDI, whereas MTZ is not, and FDX may be more effective at preventing CDI recurrence than VCM.

Abstract
Abstract
Background
Contrast-induced acute kidney injury (CI-AKI) is one of the frequently encountered and costly complications after percutaneous coronary intervention (PCI). Clinical practice guidelines strongly recommend that PCI patients should universally undergo preprocedural assessment for the risk of CI-AKI, and the contrast volume (CV) should be minimized to an achievable level, particularly among the high AKI risk patients. However, data on the CV use based on the comprehensive preprocedural risk assessment is still lacking.
Purpose
Our study aimed to 1) assess the impact of CV increase with the incidence of AKI among high AKI risk patients, and 2) retrospectively evaluate the used CV based on the preprocedural comprehensive risk assessment for patients undergoing PCI within multicenter longitudinal registry.
Methods
Between 2009 and 2018, 22,373 patients underwent PCI in 14 participating facilities, and consecutive patient data was registered. AKI was defined as a >0.3mg/dl absolute or >1.5-fold relative increase in post-PCI creatinine or new initiation of dialysis, based on the Acute Kidney Injury Network criteria. The post-procedural creatinine was defined as the highest value within 30 days after the indexed procedure. Congruent with the National Cardiovascular Data Registry (NCDR) definition, if more than 1 post-procedural creatinine level was measured, the highest value was used for determining AKI. We divided the patients into four groups according to quartile of NCDR AKI risk scores.
Results
Mean age of the patients were 68.7±11.1 years, and 79.1% were male. Mean CV use was 161.4±74.8ml. The incidence of CI-AKI was 8.9%, and was particularly high among high AKI risk patients (21.1%); CV (per 1ml linear increase) was directly associated with the occurrence of AKI (OR: 1.002 per unit in CV; 95% CI: 1.001–1.003; P<0.001) in these patients. CV during PCI decreased with the progression of chronic kidney disease (CKD), but it did not alter by the overall NCDR AKI risk score (Figure). After multivariable adjustment, CV was predicted by stage of CKD (−13.68ml; 95% CI: −12.05 to −15.30ml; P<0.001), but not by the value of pre-procedure prediction score (NCDR AKI risk score, P=0.575).
CV according to CKD/NCDR AKI risk score
Conclusions
Higher CV was directly associated with the occurrence of AKI among higher AKI risk patients. However, CV use was largely influenced by the stage of renal disease, and not with overall patient risk presented by contemporary risk scores. Our results have identified an important evidence-practice gap and emphasizes the importance of total preprocedural assessment to minimize CV and prevent subsequent AKI.

Abstract
Fosdagrocorat (PF‐04171327), a dissociated agonist of the glucocorticoid receptor, has potent anti‐inflammatory activity in patients with rheumatoid arthritis with reduced adverse effects on bone health. To identify fosdagrocorat doses with bone formation marker changes similar to prednisone 5 mg, we characterized treatment‐related changes in amino‐terminal propeptide of type I collagen (P1NP) and osteocalcin (OC) with fosdagrocorat (1, 5, 10, or 15 mg) and prednisone (5 or 10 mg) in a phase II randomized trial (N = 323). The time course of markers utilized a mixed‐effects longitudinal kinetic‐pharmacodynamic model. Median predicted changes from baseline at week 8 with fosdagrocorat 5, 10, and 15 mg were −18, −22, and −22% (P1NP), and −7, −13, and −17% (OC), respectively. Changes with prednisone 5 and 10 mg were −15% and −18% (P1NP) and −10% and −17% (OC). The probability of fosdagrocorat doses up to 15 mg being noninferior to prednisone 5 mg for P1NP and OC changes was >90%.

Abstract
This paper presents the formation of complex cross-sectional microfibers using three-dimensional microfluidic devices. The compartments and shapes of core and shell layers in the microfibers were independently controlled via three-dimensional fluidic channels fabricated by the combination of sheath units. The number of layers is easily expanded by the stacking of these units. Therefore, the highly heterogeneous microfibers of alginate hydrogel are obtained in polydimethylsiloxane structures. This widely expandable method has great potential for the development of functional and complex fiber-shaped materials.

Abstract
UNLABELLED Serum undercarboxylated osteocalcin (ucOC)/intact osteocalcin (iOC) ratio increased >1.0 in the patients undergoing hemodialysis, particularly in those with high bone turnover state. Consequently, serum ucOC/iOC ratio might lose its significance as a bone metabolic marker to indicate vitamin K deficiency in hemodialysis patients. INTRODUCTION Serum intact osteocalcin (iOC), undercarboxylated OC (ucOC), and the ucOC/iOC ratio are considered clinically relevant indices in pre-dialysis chronic kidney disease (CKD) and hemodialysis (HD) patients, despite their accumulation in uremic serum. METHODS Serum iOC and ucOC were measured along with serum intact parathyroid hormone (iPTH), bone alkaline phosphatase (BAP), and tartrate-resistant acid phosphatase (TRACP)-5b in 89 pre-dialysis CKD and 189 HD patients. RESULTS Serum iOC and ucOC showed significantly negative correlations with estimated glomerular filtration rate in pre-dialysis CKD patients, although serum ucOC/iOC ratio did not correlate. Serum ucOC was significantly greater in HD patients than in pre-dialysis CKD patients, while serum iOC did not differ significantly, resulting in serum ucOC/iOC ratio >1.0 in 135 (71.4%) out of 189 HD patients. HD patients with high serum ucOC/iOC ratio (>1.0) had a significantly younger age and significantly higher values of body mass index, serum creatinine, albumin, phosphate, iPTH, and TRACP-5b than those with low ucOC/iOC ratio (≤ 1.0). The baseline iPTH and P1NP correlated with the changes of the ucOC/iOC ratio during the 2 days of the inter-dialytic period. Multivariate analysis showed that log [ucOC/iOC] in HD patients was significantly associated with log [iPTH], log [BAP], or log [TRACP-5b]. CONCLUSIONS Serum ucOC/iOC ratio >1.0 was observed in as high as 71.4% of HD patients, preferentially with high bone turnover state, in comparison with pre-dialysis CKD patients. These data suggested that serum ucOC/iOC ratio might lose its significance as a bone metabolic marker to indicate vitamin K deficiency in HD patients.

Abstract
UNLABELLED We reported previously that serum parathyroid hormone [PTH(1-84)]/intact PTH[PTH(1-84) + PTH(7-84)] ratio provides the better marker for parathyroid function and bone turnover state than serum PTH level itself. The present study demonstrated that higher PTH(1-84)/intact PTH ratio, but not serum PTH(1-84) and intact PTH, predicted higher all-cause mortality in 177 male hemodialysis patients. INTRODUCTION We reported that PTH(1-84)/intact PTH ratio provides a clinically relevant marker for parathyroid function and the resultant bone turnover state. The purpose of our study was to investigate the association of PTH(1-84)/intact PTH ratio with all-cause mortality (ACM) in male hemodialysis patients. METHODS The study was performed for 70 months. Serum PTH in 177 male hemodialysis patients was measured with PTH(1-84)-specific whole PTH assay and intact PTH assay which cross-reacts with N-truncated PTH including PTH(7-84). RESULTS The patients (n = 177) were divided into higher and lower halves based on serum levels of PTH(1-84)/intact PTH ratio (cutoff value, 0.484), intact PTH (143.8 pg/mL), and PTH(1-84) (64.1 pg/mL). In Kaplan-Meier analysis, the higher group in whole PTH/intact PTH ratio had significantly higher ACM than the lower group (P = 0.020 by log-rank test), in contrast with the insignificant difference between the higher and lower groups in intact PTH and PTH(1-84). Multivariate Cox regression hazard analysis identified higher log [PTH(1-84)/intact PTH ratio], but not log intact PTH or log PTH(1-84) as a significant independent predictor [hazard ratio 14.428 (95% CI 2.486-83.728)] for ACM after adjustment for various factors including age, hemodialysis duration, presence/absence of diabetes mellitus, BMI, log C-reactive protein, serum albumin, calcium, and phosphate. The association existed between log [PTH(1-84)/intact PTH ratio] and ACM in those without vitamin D administration (n = 95). CONCLUSION Higher PTH(1-84)/intact PTH ratio, which provides a relevant marker for parathyroid function, may be a significant predictor of ACM in male hemodialysis patients.

Abstract
SUMMARY Increased levels of serum undercarboxylated osteocalcin, which were associated with bone metabolism markers, correlated inversely with indices of glucose metabolism (plasma glucose, hemoglobin A1C, and glycated albumin) in hemodialysis patients with abnormalities of bone metabolism. INTRODUCTION Undercarboxylated osteocalcin (ucOC), a possible marker of bone metabolism and one of the osteoblast-specific secreted proteins, has recently been reported to be associated with glucose metabolism. We tested the hypothesis that ucOC levels are associated with indices of glucose metabolism in chronic hemodialysis patients with abnormalities of bone metabolism. METHODS Serum ucOC, bone alkaline phosphatase (BAP, a bone formation marker), and tartrate-resistant acid phosphatase-5b (TRACP-5b, a bone resorption marker) were measured in 189 maintenance hemodialysis patients (96 diabetics and 93 non-diabetics), and their relationships with glucose metabolism were examined. RESULTS ucOC correlated positively with BAP (ρ = 0.489, p < 0.0001), TRACP-5b (ρ = 0.585, p < 0.0001) and intact parathyroid hormone (iPTH; ρ = 0.621, p < 0.0001). Serum ucOC levels in the diabetic patients were lower than those of non-diabetic patients (p < 0.001), although there were no significant differences in serum BAP or TRACP-5b between diabetic and non-diabetic patients. Serum ucOC correlated negatively with plasma glucose (ρ = -0.303, p < 0.0001), hemoglobin A1C (ρ = -0.214, p < 0.01), and glycated albumin (ρ = -0.271, p < 0.001), although serum BAP or TRACP-5b did not. In multiple linear regression analysis, log [plasma glucose], log [hemoglobin A1C], and log [glycated albumin] were associated significantly with log [ucOC] after adjustment for age, gender, hemodialysis duration, and body mass index but were not associated with log [BAP], log [TRACP-5b], or log [intact PTH]. CONCLUSION Increased levels of serum ucOC, which were associated with bone metabolism markers, were inversely associated with indices of glucose metabolism in hemodialysis patients.

Abstract
SUMMARY Bone mineral density of the 1/3 distal radius, ultra-distal radius, and lumbar spine correlated significantly and negatively with serum adiponectin. There was a significant positive correlation between serum adiponectin and serum NTX. Thus, adiponectin may play a role in mineral and bone disorder in chronic kidney disease stage 5 dialysis (CKD 5D) patients. INTRODUCTION Serum adiponectin, an adipocyte-produced hormone, has been reported to correlate negatively with bone mineral density (BMD) in the general population. However, little is known about the association between adiponectin and BMD in patients with CKD. METHODS BMD of the 1/3 distal and ultra-distal radius, which are enriched with cortical and cancellous bone, respectively, and the lumbar spine was measured by dual X-ray absorptiometry in 114 Japanese male hemodialysis patients (age 61.0 ± 11.1 years; hemodialysis duration 6.6 ± 3.0 years; 43.9% diabetics). Serum total adiponectin, bone formation marker (bone alkaline phosphatase, BAP), and bone resorption marker (cross-linked N-telopeptide of type I collagen (NTX)) were measured. RESULTS The BMD of the 1/3 distal radius, ultra-distal radius, and lumbar spine correlated significantly and negatively with serum adiponectin level (r = -0.229, p = 0.014; r = -0.286, p = 0.002; r = -0.227, p = 0.013, respectively). In multiple linear regression analyses, serum adiponectin was significantly and independently associated with the BMD of the 1/3 distal radius (R(2) = 0.173, p < 0.001) and ultra-distal radius (R(2) = 0.278, p < 0.001) after adjustment of age, hemodialysis duration, body weight, %fat mass, and log [intact PTH], although it was not with the BMD of the lumbar spine. There was a significant positive correlation between serum adiponectin and serum NTX (r = 0.321, p < 0.001), although there was no significant correlation between serum adiponectin and serum BAP. CONCLUSION Increased levels of serum adiponectin were associated with decrease in BMD in male hemodialysis patients. Adiponectin may play a role in mineral and bone disorder, possibly in bone resorption, of patients with CKD 5D.

Abstract
UNLABELLED In cinacalcet treatment of hemodialysis (HD) patients with secondary hyperparathyroidism (SHPT), not only intact parathyroid hormone (I-PTH), whole PTH (W-PTH), and bone markers, but also W-PTH/I-PTH ratio as proportion of active PTH(1-84) molecules were decreased. Changes in W-PTH/I-PTH ratio significantly correlated and predicted changes in bone marker. INTRODUCTION Cinacalcet partly suppresses the secretion of PTH by enhancing PTH(1-84) degradation into N-truncated fragments. The objectives of this study is to investigate the significance of the N-truncated PTH/PTH(1-84) ratio for the prediction of the effect of cinacalcet in HD patients. METHODS Serum parameters were measured during 12 weeks of oral cinacalcet administration at 25 mg daily in 39 HD patients with SHPT. RESULTS Serum Ca, Pi, W-PTH, I-PTH, and W-PTH/I-PTH ratio all decreased significantly in a time-dependent manner during cinacalcet administration. Serum tartrate-resistant acid phosphatase (TRAP) 5b reflected these changes more precisely than serum N-telopeptide of type-I collagen. At 1 week, changes in I-PTH and W-PTH correlated significantly with those in serum Pi, but not Ca. Changes in serum Pi (but not Ca) and serum W-PTH also correlated significantly with changes in serum TRAP5b at both 4 and 12 weeks, while changes in serum I-PTH correlated significantly with those in serum TRAP5b only at 12 weeks. Changes in the serum W-PTH/I-PTH ratio correlated significantly with those in serum TRAP5b at both 4 and 12 weeks, and changes in serum W-PTH/I-PTH ratio at 4 weeks showed a tendency for a correlation with changes in serum TRAP5b at 12 weeks. HD patients with a reduced W-PTH/I-PTH ratio after 4 weeks had a significantly greater reduction of TRAP5b over 12 weeks. CONCLUSION W-PTH and the W-PTH/I-PTH ratio allow estimation of the potency of cinacalcet in enhancement of PTH degradation, and thus no less reliable markers than I-PTH for reflecting cinacalcet-induced bone resorption.

Abstract
AIMS To evaluate the efficacy, safety and pharmacokinetics of pregabalin in treating neuropathic pain associated with diabetic peripheral neuropathy in Japanese patients. METHODS A randomized, double-blind, placebo-controlled, multicentre 14 week clinical trial was conducted. Japanese patients with diabetic peripheral neuropathy (n = 317) were randomized to receive placebo or pregabalin at 300 or 600 mg/day. The primary efficacy measure was a change of mean pain score from baseline to end-point from patients' daily pain diaries. RESULTS Significant reductions in pain were observed in patients treated with pregabalin at 300 and 600 mg/day vs. placebo (P < 0.05). Improvements in weekly pain scores were observed as early as week 1 and were sustained throughout the study period (300 and 600 mg/day difference from placebo at study end-point, -0.63 and -0.74, respectively). Pregabalin produced significant improvements in weekly sleep interference scores, the short-form McGill Pain Questionnaire, the Medical Outcomes Study-Sleep Scale, the 36-item Short-Form Health Survey scale, and the Patient and Clinical Global Impression of Change. Patient impressions of numbness, pain and paraesthesia were also significantly improved. Regarding treatment responders, 29.1 and 35.6% of patients treated with 300 and 600 mg/day, respectively, reported ≥ 50% improvement in mean pain scores (vs. 21.5% for placebo). Pregabalin was well tolerated; somnolence (26%), dizziness (24%), peripheral oedema (13%) and weight gain (11%) were the most common adverse events and generally were reported as mild to moderate. CONCLUSIONS Pregabalin was effective in reducing pain and improving sleep disturbances due to pain, and was well tolerated in Japanese patients with painful DPN.

Abstract
Previous studies have shown that several physiological and psychological conditions, such as hyperglycemia, diabetic neuropathy, sleep apnea syndrome and depression, may cause sleep disturbances, insomnia in diabetic patients. On the other hand, epidemiological evidences are indicating that chronic partial sleep loss may increase the risk of diabetes. Laboratory studies have shown that sleep restriction is associated with an increase in sympathetic nervous activity and a decrease in insulin sensitivity without adequate compensation in beta-cell function, resulting in an impact on glucose homeostasis and an elevated risk of diabetes. Sleep curtailment is also associated with a dysregulation of the neuroendocrine control of appetite, with a reduction of the satiety factor, leptin, and an increase in hunger-promoting hormone, ghrelin. The adverse impact of sleep deprivation on energy homeostasis is likely to be driven by increased activity of neuronal populations expressing in orexin system that promotes waking, feeding and energy-expenditure.

Abstract
We herein present 2 cases of metastatic lung tumor derived from uterine leiomyosarcoma. In the case 1, a 59-year-old woman was admitted to our hospital to examine abnormal shadow detected on chest X-ray. She had undergone hysterectomy and oophorectomy for uterine leiomyosarcoma 19 months previously. A round 3 cm mass in the right lung (S10) was seen on chest X-ray and computed tomography (CT). No other distant metastases or local recurrence were found, and the right lower lobectomy was perfomed under the clinical diagnosis of metastatic lung tumor. Postoperative pathologic examination revealed the tumor as a metastatic leiomyosarcoma. The patient recovered uneventfully, and there have been no signs of recurrence for 26 months after the pulmonary resection. In the case 2, a 58-year-old woman, who had undergone hysterectomy and oophorectomy for uterine leiomyosarcoma 7 months previously, was admitted to our hospital for further examination of pulmonary tumors on chest X-ray. Two tumors were recognized in the left lung (S8 and S10) on chest X-ray and CT. No other distant metastases or local recurrence were found, and the left lower lobectomy was performed under the clinical diagnosis of metastatic lung tumors. Pathological examinations revealed smooth muscle cells with nuclear pleomorphism and high mitotic indices. The tumors proved to be lung metastases derived from uterine leiomyosarcoma. Postoperative course was uneventful. However, brain metastasis was found 1 month after the pulmonary resection, and she underwent resection of brain metastasis. Two months after the brain metastasectomy, local recurrence of the brain tumor developed and re-resection followed by stereotactic radiotherapy was performed. Furthermore, intrapelvic recurrence was found 4 months after the pulmonary resection. Exploratory laparotomy revealed the tumor was unresectable, and she received 4 courses of chemotherapy (paclitaxel and carboplatin). For metastatic lung tumor from uterine leiomyosarcoma, surgery has been considered the best choice. However, for patients with uterine leiomyosarcoma who cannot be treated surgically because of multiple metastatic tumors or poor surgical risk chemotherapy (paclitaxel and carboplatin) or stereotactic radiotherapy can be strategies.

Abstract
A 47-year-old man was admitted to our hospital for treatment of massive hemoptysis. He was intubated and underwent bronchial arterial embolization because of this deteriorating respiratory state and uncontrollable hemoptysis. Computed tomography (CT) of the chest showed a 1-cm nodular shadow in the peripheral apical lobe (S1) of the right lung. He underwent right upper lobectomy for the purpose of preventing re-hemorrhage as well as making the definitive diagnosis of nodular shadow in S1 of the right lung. Intraoperative pathological examination revealed the nodule as adenocarcinoma, and mediastinal lymphadenectomy was added to the right upper lobectomy. The patient recovered uneventfully, and there has been no sign of recurrence for 15 months after the operation.

Abstract
OBJECTIVE To investigate whether polymorphisms of interleukin (IL)-18 gene confer susceptibility to Graves' disease (GD) and Graves' ophthalmopathy (GO). DESIGN We performed a case control study on polymorphisms of IL-18 gene in Japanese patients with GD (n = 435), and healthy control subjects without antithyroid autoantibodies or family history of autoimmune disorders (n = 255). The C-4675G, C-607A, and G-137C polymorphisms in the promoter region and A105C (exon 5) polymorphism were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) using restriction enzymes, sequence-specific PCR, and PCR-direct sequencing methods. RESULTS None of the polymorphisms in the IL-18 gene were associated with development of Graves' disease. The CC genotype and C allele frequencies of IL-18 gene G-137C polymorphism tended to be greater in patients with ophthalmopathy than in patients without evident ophthalmopathy. However, the differences were not statistically significant. Although there were three major haplotypes, none of the haplotypes were statistically associated with susceptibility to GD or ophthalmopathy. CONCLUSIONS These results suggest that IL-18 gene polymorphisms are not major genetic factors for susceptibility to GD in a Japanese population. Further studies with adequate sized data set in the subset analyses for GO are needed.

Abstract
AIMS This study aimed to investigate whether interleukin-18 (IL-18) gene polymorphisms are associated with the development of antibody against the 65-kDa isoform of recombinant human glutamic acid decarboxylase (GAD65Ab) in patients with Graves' disease. METHODS A total of 398 unrelated Japanese patients with Graves' disease, with and without GAD65Ab, were recruited. Three single nucleotide polymorphisms in the IL-18 gene were examined and the polymorphic allele and the genotype and haplotype frequencies calculated. RESULTS The frequency of the GG genotype at position -4675 of the IL-18 gene was significantly lower in Graves' disease patients with GAD65Ab than those without (4% vs. 24%, P = 0.0126). The -4675C allele frequency was significantly greater in patients with GAD65Ab than those without (69% vs. 53%, P = 0.0168). The homozygous -4675G/-607A/-137G haplotype was less common in Graves' disease patients with GAD65Ab than those without (4% vs. 23%, P = 0.0144). CONCLUSIONS These findings in a Japanese population indicate that Graves' disease patients carrying the GG genotype at position -4657 of the promoter of the IL-18 gene or a gene in linkage disequilibrium with the -4675G/-607A/-137G haplotype have a low risk for the development of GAD65Ab in Graves' disease.

Abstract
Graves' disease (GD) is an autoimmune disorder with genetic predisposition. IL-13 is an important mediator of antiinflammatory immune responses and is expressed in the thyroid and orbit. The aim of the present study was to investigate whether IL-13 gene polymorphisms are associated with the development of GD. IL-13 gene polymorphisms were studied in Japanese GD patients (n = 310) and healthy control subjects without antithyroid autoantibodies or a family history of autoimmune disorders (n = 244). A C/T polymorphism at position -1112 of the promoter region was measured using the direct sequencing method, and an Arg(130)Gln (G2044A) polymorphism in exon 4 was examined using the PCR-restriction fragment length polymorphism method. There was a significant decrease in -1112T allele frequency in GD patients compared with controls (16% vs. 23%; P = 0.0019). The frequency of the 2044A allele on exon 4 also appeared lower in GD patients compared with controls. Haplotype analysis showed a significant decrease in the -1112T/2044A haplotype in GD patients. There was no association between IL-13 gene polymorphisms and ophthalmopathy, severity, or serum IgE levels. In conclusion, IL-13 gene polymorphisms are associated with GD susceptibility in Japan.

Abstract
In order to clarify the role of apoptosis and the expression of Bcl-2 family proteins in the pathology of Graves' disease (GD), we evaluated the apoptosis by in situ end-labeling of fragmented DNA and the expression of Bcl-2, Bax and Bak by immunohistochemistry in thyroid tissues from 20 patients with GD and in normal thyroid tissues from 6 patients with follicular adenoma (N). Apoptotic nuclei were found in thyrocytes and in germinal center of lymphoid follicles. Bcl-2 was strongly expressed in both GD and N thyrocytes. Bax was not expressed in either GD or N thyrocytes. Bak was expressed in thyrocytes from 5 of 20 patients with GD, while it was detected in all N thyrocytes. In lymphoid follicles Bcl-2 was expressed in the mantle zone, while Bax and Bak were both expressed in the germinal center. The percentage of apoptotic nuclei in GD thyrocytes was low (0~3.6%), and negatively correlated with the weight of the thyroid glands resected (rs = -0.43, P<0.05). It was greater in Bak-positive GD thyrocytes than in Bak-negative ones (mean +/- SD; 1.7 +/- 0.7% vs. 0.7 +/- 0.9%, P<0.05). These findings suggest that the differential expression of Bcl-2 family proteins in both thyrocytes and lymphoid follicles may be involved in the pathology of GD.

Abstract
This case report describes a 46-year-old man whose first symptom was an attack of acute flank pain, followed by the gradual onset neurological symptoms. We demonstrated a small nidus and serpentine signal-void area in the spinal cord by MRI and diagnosed a glomus type of spinal arteriovenous malformation (AVM). Flank pain is a rare initial finding in an adult with spinal AVM. In cases with acute flank pain, neurologists should consider spinal AVM as a differential diagnosis.

Abstract
Catechol-O-methyltransferase (COMT) is an enzyme that inactivates catecholamines, including levodopa. An amino acid change (Val-108-Met) in the COMT protein has been found to result in a change from high to low enzyme activity. In the present study, we genotyped 121 Japanese patients with Parkinson's disease (PD) and 100 controls. Comparison of the allele frequencies revealed that homozygosity for the low-activity allele was significantly more common among PD patients than the controls (p = 0.047, odds ratio = 3.23). In addition, homozygosity for the low-activity allele was overrepresented in PD patients that exhibited the 'wearing-off' phenomenon (p = 0.045, odds ratio = 3.82) or dyskinesia (p = 0.030, odds ratio = 4.80) compared with controls, although these differences were not significant after Bonferroni's correction. Our results may help understand the mechanism that cause complications of levodopa therapy in PD patients.

Abstract
Graves' disease (GD) is an autoimmune disorder with genetic predisposition. Interferon-gamma (IFN-gamma) is an important mediator of inflammatory and immune responses. The aim of the present study was to investigate whether the polymorphism of IFN-gamma gene is associated with the development of GD or with clinical course during the antithyroid drug therapy. We have studied the CA repeat polymorphisms in the first intron of IFN gamma gene in Japanese patients with GD (n = 162) and healthy control subjects without antithyroid autoantibodies or family history of autoimmune disorders (n = 133). There was no difference in allele frequency of IFN-gamma gene polymorphism between patients with GD and control subjects. However, the allele 4 (15 CA repeats) frequency was significantly greater in patients whose antithyrotropin receptor antibody (TRAb) became negative within 3 years by antithyroid drug treatment than those with consistently positive TRAb for more than 3 years (34.1% vs. 15.7%, chi2 = 8.545, p = 0.0035, pc = 0.049). The in vitro production of IFN-gamma by concanavalin A-stimulated peripheral blood mononuclear cells was significantly smaller in control subjects with the allele 4 compared to those with the other alleles. In conclusions, the CA repeat polymorphism of the IFN-gamma gene might be associated with the outcome of anti-thyroid drug treatment.

Abstract
CSF hypocretin-1 was measured in 28 Guillain-Barré syndrome (GBS), 12 Miller-Fisher syndrome, 12 chronic inflammatory demyelinating polyneuropathy (CIDP), and 48 control subjects. Seven GBS subjects had undetectably low hypocretin-1 levels (<100 pg/mL). Hypocretin-1 levels were moderately reduced in an additional 11 GBS, 5 Miller-Fisher syndrome, and 1 CIDP subject. Low levels in GBS occurred early in the disease and were associated with upper CNS level abnormalities.
