Abstract
We compared the effects of melatonin, an antioxidant and sleep inducer in humans, and rilmazafone hydrochloride, a hypnotic, in elderly patients with nocturia. Patients received either melatonin (2 mg/day; n = 20) or rilmazafone (2 mg/day; n = 22) for 4 weeks. There were no significant differences in the mean age, the quality of life (QoL) score and the serum melatonin levels between the two groups at baseline. After 4 weeks' treatment, the number of nocturnal urinations was significantly decreased and the QoL score was significantly improved in both groups. There was no significant difference between the patient-reported effectiveness ratings between the two groups. The serum melatonin level was significantly increased in the melatonin-treated group, but it remained unchanged in the rilmazafone-treated group. Melatonin and rilmazafone were equally effective for nocturia in the elderly. We recommend that the problems of sleep disturbance should be considered when choosing a therapy for nocturia.

Abstract
WHAT IS KNOWN AND OBJECTIVE There are no clinical reports that have compared topiroxostat, a selective xanthine oxidase inhibitor, with allopurinol in serum urate-lowering efficacy. The aim of this study was to compare the efficacy and safety of topiroxostat and allopurinol in Japanese hyperuricemic patients with or without gout. METHODS A phase 3, multicentre, randomized, double-blind, double-dummy, active-controlled, parallel-group study conducted in Japan. Patients who had inadequate serum urate levels (a gout patient: serum urate level ≥416·4 μmol/L; an asymptomatic hyperuricemic patient with specific complications (urinary lithiasis, hypertension, hyperlipidemia and/or diabetes): serum urate level ≥475·8 μmol/L; and an asymptomatic hyperuricemic patient with no specific complications: serum urate level ≥535·3 μmol/L) were randomized to topiroxostat 120 mg/day or allopurinol 200 mg/day, with an equal allocation ratio, for 16 weeks. To prevent the onset of gouty arthritis by rapid serum urate reduction, these doses were increased in a stepwise manner. The primary efficacy endpoint was the per cent change in serum urate level from baseline to the final visit. RESULTS AND DISCUSSION Overall, 206 patients were randomly assigned to topiroxostat and allopurinol. Two hundred and three patients (allopurinol: n = 105, topiroxostat: n = 98) received at least one dose of the study drug and had their serum urate level assessed at least once. The baseline characteristics were comparable between groups. The mean age of patients was 53·0 ± 11·4 years and 99% of patients were male. The primary efficacy endpoint was -34·3 ± 11·1% in the allopurinol group (n = 105) and -36·3 ± 12·7% in the topiroxostat group (n = 98). Non-inferiority of the serum urate-lowering efficacy of topiroxostat to allopurinol was proved by the predefined non-inferiority margin (95% confidence interval, -5·3 to 1·3%). The overall incidences of adverse events and adverse drug reactions were similar between both groups. WHAT IS NEW AND CONCLUSION Topiroxostat 120 mg/day provides non-inferior serum urate reduction compared with allopurinol 200 mg/day and is well tolerated in Japanese hyperuricemic patients with or without gout.

Abstract
PURPOSE To relieve the chronic shortage of donor kidneys, we conducted a prospective kidney transplantation trial using kidneys removed from 10 unrelated patients (51 to 79 years of age) who had undergone nephrectomy for small renal cell carcinoma (1.5 to 3.9 cm) of low-to-moderate complexity based on RENAL (radius, exophytic/endophytic properties, nearness of tumor to the collecting system or sinus in millimeters, anterior/posterior location relative to polar lines) nephrometry (objective description helpful for operative indication and planning). METHODS Donors were selected from among 15 patients who opted to undergo nephrectomy for small renal cell carcinoma. A total of 76 dialysis patients 34 to 85 years of age who agreed to undergo restored kidney transplantation were recruited as transplant candidates. RESULTS In stage 1 (5 cases), high-risk patients were selected without human leukocyte antigen testing, and accelerated acute rejection occurred in 4 of 5 recipients. This trial was subsequently extended with human leukocyte antigen testing, and an additional 5 patients were enrolled in stage 2. Eight recipients, including 4 recipients with a history of renal transplantation, experienced rejection; 1 patient resumed dialysis 35 months after transplantation. The most recent serum creatinine levels ranged from 1.10 to 3.19 mg/dL in the 9 recipients with functioning grafts and from 0.84 to 4.68 mg/dL in the 10 donors. No tumor recurrence was noted at 32 to 58 months after surgery in either the recipients or the donors. CONCLUSIONS Restored kidney transplantation using kidneys with a small renal tumor seems suitable for carefully selected high-risk recipients and, in particular, elderly kidneys can also function well. Avoiding cancer transmission, fair recipient selection, close follow-up, and a well-organized tracking system warrant further study.

Abstract
Background Quality of life (QoL) is routinely assessed and evaluated in medical research. However, in Japan, there is a lack of solid cutoff criteria for evaluating QoL improvement in chronic noncancer pain management. The present study was conducted to identify the minimal clinically important change (MCIC) of the Japanese version of EuroQol-5D 3L(EQ-5D) utility score and numeric rating scale (NRS) with an emphasis on chronic noncancer pain. Methods The data source for this post hoc research was the post-marketing surveillance (PMS) data for a tramadol/acetaminophen combination tablet, which was previously conducted in real-world settings. The parameters extracted from the PMS data were sociodemographic characteristics, NRS, EQ-5D, and dichotomous physician’s global impression of treatment effectiveness (PGI). The optimal cutoff points of MCIC for EQ-5D utility and NRS scores were evaluated using receiver operating characteristics (ROC) analysis. An anchor-based approach using PGI was applied. Results Data of 710 patients with chronic noncancer pain were extracted from the PMS database. The NRS score decreased by 2.7 (standard deviation, 2.3) points, whereas the EQ-5D score increased by 0.16 (0.20) points at 4 weeks from baseline. The changes from baseline in NRS and EQ-5D were significantly correlated (r = 0.53, p < 0.001). The estimated optimal cutoff points of MCIC for EQ-5D and NRS were 0.10 and −2.0 points, respectively. The area under the curve of ROC was > 0.80 in both analyses. Conclusion These results demonstrated novel cutoff criteria for the Japanese version of EQ-5D, focusing on patients with chronic noncancer pain. The obtained criteria were fairly consistent and can be confidently utilized as an evaluation tool in medical research on chronic noncancer pain in Japan, with additional functionality and usability for QoL assessment in pain management practice. Trial registration The data source of this post hoc research was a PMS study with the identifier number UMIN000015901 at umin.ac.jp, UMIN clinical trial registry (UMIN-CTR).

Abstract
OBJECTIVE To evaluate the overall safety profile and clinical effectiveness of tramadol hydrochloride/acetaminophen (TA) combination tablets in Japanese patients with chronic noncancer pain unrelieved by non-opioid drugs for up to 12 weeks in real-world practice. RESEARCH DESIGN AND METHODS This survey was a multicenter, prospective, longitudinal registry on the use of TA as a newly initiated pain treatment for chronic noncancer pain incurable by non-opioid analgesics that was conducted under the Good Post Marketing Study Practice regulation controlled by the Japan Ministry of Health, Labor and Welfare. Collected data included socio-demographics, treatment information, incidence of adverse drug reactions (ADRs), numerical rating scale for intensity of pain, EuroQol-5D (EQ-5D) scale, and physician's global impression (PGI) during the 12 week observation period. RESULTS A total of 1316 patients were registered. ADRs were reported in 259 patients (20.5%); most events were nonserious (99.4%), including nausea (n = 87 [6.9%]), constipation (n = 63 [5.0%]), dizziness and somnolence (n = 29 [2.3%] each), and vomiting (n = 21 [1.7%]). No event related to drug dependence or respiratory depression was reported. In addition, 82.8% of patients showed acceptable effectiveness based on PGI at Week 4. Numerical rating scale for intensity of pain and EQ-5D utility scores were improved by -2.7 (SD 2.3) and 0.16 (SD 0.20) at Week 4, respectively, and the improvement was maintained until Week 12. CONCLUSION This is a first report to evaluate the risk-benefit profile of TA in Japanese real-world practice using large size registry data. It is suggested that the favorable risk-benefit balance of TA was confirmed for patients with chronic noncancer pain unrelieved by non-opioid drugs in real-world practice. Limitations of this study were those inherent to open-label and non-interventional study designs. TRIAL REGISTRATION This registry survey is registered at umin.ac.jp (identifier: UMIN000015901).

Abstract
Transsphenoidal surgery is currently employed to treat complex lesions beyond the sella turcica; however, the procedure can be limited by difficulties encountered in dealing with small blood vessels, deep and narrow working spaces, and awkward working angles. To overcome these problems, we have developed a pulsed laser-induced liquid jet system that can dissect tumor tissue while preserving fine blood vessels within deep and narrow working spaces. We have previously evaluated the utility and safety of this procedure. However, the effects of the pulsejet after being injected into the brain are not yet well understood. Especially, the behavior of the stress distribution created by the jet is important because it has recently been reported that high acoustic pressures can affect the brain. In this study, we measured internal stress distributions in a gelatin simulated-brain using photoelasticity experiments. We used a high-speed camera with an image sensor on which an array of micropolarizers was attached to measure the stresses and the shear wave created when the pulsejet enters the simulated brain.

Abstract
Rose flowers have long delighted humans as ornamental plants. To improve the ornamental value of roses it is necessary to understand the regulatory mechanisms of flowering. We previously found that flowering time is controlled by three minor quantitative trait loci (QTLs) and a major QTL co-localised with RoFT. In this study, we isolated three RoFT alleles encoding completely identical amino acid sequences from the parents of a mapping population. Correlation analysis of the RoFT genotypes and flowering time phenotypes in the mapping population showed that the RoFT_f and RoFT_g alleles contribute to the early-flowering phenotype, while the RoFT_e allele contributes to the late-flowering phenotype. We developed two novel cleaved amplified polymorphic sequence (CAPS) markers based on the genomic sequences of the RoFT alleles and clearly showed that the relationship between RoFT genotype and flowering time was applicable to 12 of 13 cultivated roses grown at the Higashiyama Botanical Gardens, Japan. Allele-specific expression analysis using a reverse transcription CAPS assay suggested that these RoFT alleles are regulated differentially at the transcription level. Furthermore, transgenic Arabidopsis thaliana plants ectopically expressing the RoFT gene showed an early-flowering phenotype. Conversely, in roses, RoFT was continuously expressed after floral bud formation, and RoFT transcript accumulation reached its peak after that of the floral meristem identity gene RoAP1b. These data suggest that RoFT may be essential not only for floral transition but also for normal floral development and flowering in roses.

Abstract
Terahertz time-domain attenuated total reflection measurements of monosaccharide (glucose and fructose) and disaccharide (sucrose and trehalose) solutions from 0.146 M to 1.462 M were performed to evaluate (1) the hydration state and (2) the destructuring effect of saccharide solutes on the hydrogen bond (HB) network. Firstly, the extent of hydration water was determined by the decreased amount of bulk water with picosecond relaxation time that was replaced by that with much longer orientational relaxation time. As a result, we found glucose and trehalose exhibits stronger hydration capacity than fructose and sucrose, respectively, despite of the same number of the hydroxyl groups. For each saccharide, the hydration number tended to decrease with solute concentration. Secondly, the destructuring effect of these saccharide solutes on the HB network of the surrounding bulk water was discussed from the perspective of the fraction of non-hydrogen-bonded (NHB) water isolated from the HB network. We found the fraction of NHB water molecules that are not engaged in the HB network monotonously increased with saccharide concentration, indicating saccharide solutes promote the disruption of the water HB network. However, no noticeable differences were confirmed in the fraction of NHB water between glucose and fructose or between sucrose and trehalose. In contrast to hydration number, the number of NHB water produced by a single saccharide solute was less dependent on solute concentration, and three monosaccharide/disaccharide solutes were found to produce one/two NHB water molecules.

Abstract
BACKGROUND Social functioning is an important outcome for patients with schizophrenia. To evaluate the effects of paliperidone extended-release (PAL-ER) on social function, symptomatology, and safety in the routine clinical practice, we conducted a 1-year post-marketing surveillance study of PAL-ER. We also explored relationships between symptomatic improvement and socially functional outcome in patients with schizophrenia. PATIENTS AND METHODS Patients with an established diagnosis of schizophrenia were allowed flexible 3-12 mg/day dosing during the surveillance. Patients were assessed on social functioning using the Social and Occupational Functioning Assessment Scale (SOFAS) and on symptomatology using the Clinical Global Impression-Schizophrenia scale. All adverse events (AEs) were also collected. RESULTS A total of 1,429 patients were enrolled in the surveillance study, of whom 1,405 were evaluable for safety and 1,142 were evaluable for efficacy. The treatment discontinuation rate for any reason during the observation period was 34.66%. Significant improvements were observed on both Social and Occupational Functioning Assessment Scale and Clinical Global Impression-Schizophrenia scale during the observation period. The percentage of patients with socially functional remission (SOFAS ≥61) also increased significantly. A significant association between early improvements in positive symptoms, sex, severity of negative symptoms at baseline, and socially functional remission was observed. A total of 33.52% of patients had AEs and 8.75% of patients had serious AEs. Despite the recommendation of monotherapy with PAL-ER, 65.84% of patients were given additional antipsychotics (polypharmacy). Post hoc comparisons of monotherapy versus polypharmacy revealed that the monotherapy group had better outcomes and fewer AEs than the polypharmacy treated group. The improvement in social functioning and the rate of socially functional remission did not differ between groups. CONCLUSION PAL-ER treatment showed effective symptom control and improvement in social functioning. The data suggest that early response to antipsychotic treatment should be important for functional outcomes.

BACKGROUND Evaluating the accurate responses of the cardiovascular system to external stimuli is important for a deeper understanding of cardiovascular homeostasis. However, the responses should be distorted by the conventional time domain analysis when a frequency of the effect of external stimuli matches that of intrinsic fluctuations. OBJECTIVES The purpose of this study is to propose a mixed signal processing of time domain and respiratory phase domain to extract the response waveforms of heartbeat and blood pressure (BP) to external stimuli and to clarify the physiological mechanisms of swallowing effects on the cardiovascular system. METHODS Measurements were conducted on 12 healthy humans in the sitting and standing positions, with each subject requested to swallow every 30 s between expiration and inspiration. Waveforms of respiratory sinus arrhythmia (RSA) and respiratory-related BP variations were extracted as functions of the respiratory phase. Then, respiratory effects were subtracted from response waveforms with reference to the respiratory phase in the time domain. RESULTS As a result, swallowing induced tachycardia, which peaked within 3 s and recovered within 8 s. Tachycardia was greater in the sitting position than during standing. Furthermore, systolic BP and pulse pressure immediately decreased and diastolic BP increased coincident with the occurrence of tachycardia. Subsequently, systolic BP and pulse pressure recovered faster than the R-R interval. CONCLUSIONS We conclude that swallowing-induced tachycardia arises largely from the decrease of vagal activity and the baroreflex would yield fast oscillatory responses in recovery.
