Abstract
Ultrasound imaging is a less invasive imaging modality without radiation exposure and is available for repeated tests. It is the gold standard examination for diagnosing and managing disorders of the urinary tract, including lower urinary tract dysfunction (LUTD) in pediatric urology. Ultrasound imaging is effective for screening underlying diseases and determining treatment strategies. Ultrasound examination at the bedside should focus on post-voided residual urine (PVR), bladder wall thickening, renal morphology, and rectal diameter. Since PVR must be tested immediately after voiding, examining infants who cannot complain of the urge to void is difficult. PVR measurement combined with a 4-h voiding observation or alarm system activated by urine is recommended for these infants. Early diagnosis is important because LUTD is associated with the risk of morbid residual urine and high voiding pressure, which can result in renal deterioration, urinary leakage, and febrile urinary tract infection.

Abstract
OBJECTIVES Preserving sufficient oral function and maintaining aadequate nutrition are essential for preventing physical frailty and the following long-term care. We recently developed the 6-month Comprehensive Awareness Modification of Mouth, Chewing And Meal (CAMCAM) program, in which participants gather monthly to learn about oral health and nutrition while eating a textured lunch together. This study examined whether the CAMCAM program could improve attitude and behavior towards oral health, mastication, and diet as well as ameliorate oral frailty in community-dwelling older adults. DESIGN Single-arm pre-post comparison study. SETTING AND PARTICIPANTS A total of 271 community-dwelling adults (72.3 ± 5.7 years of age; 159 women [58.7%]) in 4 Japanese municipalities were recruited, of which 249 participants (92%) were assessed at the final evaluation. INTERVENTION Participants gathered once a month at community centers to learn about oral health and nutrition while eating a "munchy" textured lunch containing proper nutrition. MEASUREMENTS Oral frailty, frailty, and eating behavior were evaluated with the Oral Frailty Index-8 (OFI-8), Kihon checklist (KCL), and CAMCAM checklist, respectively. Participants were divided into Oral frailty (OF) and Robust groups according to OFI-8 scores. The differences in KCL and CAMCAM checklist results between the OF and Robust groups were statistically tested along with changes in scores after the program. RESULTS KCL and CAMCAM checklist scores were significantly lower in the OF group at the initial assessment. OFI-8 and KCL findings were significantly improved in the OF group after completing the program (all P <0.05). Regarding the CAMCAM checklist, awareness of chewing improved significantly in the Robust group (P=0.009), with a similar tendency in the OF group (P=0.080). CONCLUSION The findings of this pilot study suggest that the CAMCAM program may improve both oral and systemic frailty in addition to attitudes towards chewing, oral health, and meals, especially in individuals with oral frailty. The CAMCAM program merits expansion as a community-based frailty prevention program.

Abstract
Abstract
Background
Fibrates activate peroxisome proliferator-activated receptor (PPAR)-α which is associated with lipid metabolism. Bezafibrate is a non-selective PPAR-α agonist, whereas pemafibrate has been developed as a higher selective PPAR-α agonist.
Objective
The efficacy and safety of pemafibrate for 24-week in patients with dyslipidemia was examined in comparison with bezafibrate.
Methods
Sixty patients with hypertriglyceridemia (fasting triglyceride (TG) level of ≥150 mg/dL) were treated with pemafibrate of 0.2 mg/day or bezafibrate of 400 mg/day for 24-week in a randomized cross-over study. Percent change from baseline in TG levels was the primary endpoint, and that in HDL-C and apolipoprotein A-I (Apo A-I) levels was the secondary endpoints.
Results
A significantly greater reduction in TG percent change was observed in pemafibrate than in bezafibrate (−46.1% vs. −34.7%, p<0.001). There was no significant difference in HDL-C percent change between pemafibrate and bezafibrate (18.4% vs. 14.0%, p=0.067), whereas Apo A-I percent change was significantly greater in pemafibrate than in bezafibrate (9.2% vs. 5.7%, p=0.018). Pemafibrate and bezafibrate significantly decreased alanine aminotransferase (ALT) and gamma-glutamyltransferase (γ-GT) levels, and pemafibrate showed a greater reduction than bezafibrate (ALT: −21.9% vs. −10.6%, p=0.048; γ-GT: −43.5% vs. −33.1%, p=0.025). Creatinine levels significantly increased in both treatments (both p<0.001), however, creatinine percent change was significantly smaller in pemafibrate than in bezafibrate (5.72% vs. 15.5%, p<0.001). There was no difference in frequency of adverse event (AE) or serious AE between two treatments, but frequency of creatinine elevation (≥0.5 mg/d and/or 25%) was significantly higher in bezafibrate than in pemafibrate (16/60 vs. 3/60, p=0.004).
Conclusion
As compared with bezafibrate, pemafibrate is more effective to reduce TG levels and to elevate Apo A-I levels, and it is safer in terms of liver and renal function.

Background
Orthostatic hypotension (OH) is sometimes observed during cardiac rehabilitation in patients with surgery for aortic dissection. However, little is known about the primary determinant of OH and influence of surgical range on incidence of OH.
Purpose
The aim of this study was to elucidate the incidence of OH in patients with surgery for aortic dissection, and compare it between the patients with ascending aortic replacement surgery (ascending group) and those with ascending aorta and hemiarch or total arch replacement surgery (arch group).
Methods
We analyzed 59 patients who underwent emergent surgery due to Stanford type A aortic dissection from January 2014 to March 2018, and compared the incidence of OH between ascending group (n = 28, age 69.8 ± 11.3 years) and arch group (n = 31, age 64.1 ± 13.0 years).
Results
The incidence of OH in total patients was 30.5%. There were no significant differences in patient characteristics including body tall, body weight, antihypertensive use and progress of rehabilitation between 2 groups. The arch group showed a significant higher incidence of OH as compared with ascending group (arch group: 46.4% vs. ascending group: 16.1%, p = 0.03). Moreover, the patients who occurred OH were significantly taller than those who did not occur OH.
Conclusions
OH was observed in about one third of patients with surgery for aortic dissection and it showed a close relationship with patient’s height and the range repaired by surgical operation. More careful cardiac rehabilitation is needed for tall patients with large area replacement of aorta.

Abstract
Abstract
Background
There are two types of circulating proprotein convertase subtilisin/kexin type 9 (PCSK9), mature and furin-cleaved. Most types of lipoprotein(a) [Lp(a)], an independent risk factor of cardiovascular events, bound to mature PCSK9.
Purpose
This study examined the effects of monoclonal anti-PCSK9 antibody on plasma PCSK9 and Lp(a) levels in acute myocardial infarction (MI).
Methods
Acute MI patients (n=36) were randomly divided into evolocumab (140 mg; n=17) and non-evolocumab (n=19) groups. Changes in plasma PCSK9 and Lp(a) levels were monitored before and 1, 3, 5, 10, and 20 days after evolocumab administration.
Results
In the non-evolocumab group, plasma levels of mature PCSK9, furin-cleaved PCSK9, and Lp(a) (236.4±57.3 ng/mL, 22.4±5.8 ng/mL, and 19.2. ± 16.5 mg/dL, respectively) significantly increased by day 3 (408.8±77.1 ng/mL, P<0.001; 47.2±15.7 ng/mL, P<0.001; and 39.7±21.3 mg/dL, P<0.005, respectively) and returned to the baseline by day 10 or 20. In the evolocumab group, mature PCSK9 significantly increased by >1000 ng/mL with a simultaneous decline of furin-cleaved PCSK9 below the measurement sensitivity level after day 3. The incremental area under the curve for plasma Lp(a) levels was significantly smaller in the evolocumab group compared with the non-evolocumab group (P=0.038).
Conclusion
Mature and furin-cleaved PCSK9 are transiently upregulated after MI onset. Evolocumab significantly increases mature PCSK9 and decreases furin-cleaved PCSK9 and might inhibit transient increase of plasma Lp(a) in acute MI.

Abstract
Abstract
Background
Chronotropic incompetence (CI) is sometimes observed during exercise training of cardiac rehabilitation in patients with cardiac surgery, however, little is known concerning the differences between patients with mitral valve (MV) and aortic valve (AV) surgery.
Purpose
Because the possibility exists that cardiac sympathetic nerves might be impaired by left atrium incision, we hypothesized that the incidence of CI was higher in patients with MV surgery (Mitral Valve Replacement and Mitral Valvuloplasty) as compared with patients with AV surgery (Aortic Valve Replacement). And if so, which factor determines the exercise capacity of patients after MV surgery. We thus aimed this study to elucidate the hypothesis with cardiopulmonary exercise testing (CPX).
Methods
We performed CPX by ramp loading with ergometer exercise in total 61 patients who had undergone elective cardiac valve operation (25 patients with MV surgery, age 59.2±9.9 years; 36 patients with AV surgery, age 64.6±12.3 years). We analyzed chronotropic response index (CRI), peak oxygen uptake (peak VO2/W), anaerobic threshold (AT), and peak oxygen pulse (peak VO2/HR) with CPX, and blood hemoglobin concentration (Hb).
Results
The value of CRI was significantly decreased in the patients with MV surgery compared with those with AV surgery (MV; 0.19±0.10 vs. AV; 0.41±0.17, p<0.001). Peak VO2, peak VO2/HR and Hb were not significantly different between patients with MV and those with AV surgery. Patients with MV surgery showed correlations between peak VO2 and Hb (r=0.45, p<0.05), AT and Hb (r=0.52, p<0.01), and a strong correlation between peak VO2 and peak VO2/HR (r=0.63, p<0.001), but not in those with AV surgery.
Conclusions
The present study demonstrated that higher incidence of CI was shown in patients with MV surgery as compared with those with AV surgery. The exercise capacity of patients with MV surgery was determined by peak VO2/HR and Hb. These results suggest that 1) left atrium incision impairs cardiac sympathetic nerves and causes CI, 2) peak VO2/HR which is consisted of arterio-venous oxygen difference and Hb is critical indicator for exercise capacity in patients with MV surgery with CI.

Abstract
BACKGROUND AND PURPOSE Branch atheromatous disease (BAD) is one of the stroke subtypes caused by occlusion at the origin of a deep penetrating artery of the brain and is associated with a microatheroma or a junctional plaque. Patients with BAD often develop progressive worsening of neurologic deficits, although these patients often present minor stroke with clinical characteristics of lacunar syndrome at the onset. Pentraxin 3 (PTX3) is known to be a key molecule involved in the pathogenesis of atherosclerosis. Although a high level of serum PTX3 is observed in patients with acute coronary syndrome, there are no reports on PTX3 levels in patients with BAD. This study aimed to investigate whether serum PTX3 levels can distinguish BAD from other stroke subtypes. METHODS We investigated 93 patients with ischaemic stroke. Serum PTX3 levels on admission were measured using enzyme-linked immunosorbent assay in patients with BAD and those with other stroke subtypes (each n ≥ 20). RESULTS The median PTX3 levels in patients with BAD (4840 pg/mL) were higher than those with other subtypes of stroke (3397 pg/mL in lacunar stroke, 1298 pg/mL in large-artery atherosclerosis, 1470 pg/mL in cardioaortic embolism and 1006 pg/mL in control) (all P < 0.01). CONCLUSION Our results suggest that elevated serum PTX3 levels might predict the diagnosis of BAD at a very early stage.

Abstract
The presence of stem cells within the dental-pulp tissue as well as their differentiation into a new generation of functional odontoblast-like cells constitutes an important step of the dentin-pulp regeneration. Recent investigations demonstrated that the complement system activation participates in 2 critical steps of dentin-pulp regeneration: pulp progenitor's recruitment and pulp nerve sprouting. Surprisingly, its implication in odontoblastic differentiation has not been addressed yet. Since the complement receptor C5a receptor-like 2 (C5L2) is expressed by different stem cells, the aim of this study is to investigate if the dental pulp stem cells express C5L2 and if this receptor participates in odontoblastic differentiation. Immunohistochemistry performed on human third molar pulp sections showed a perivascular co-localization of the mesenchymal stem cell markers STRO1 and C5L2. In vitro immunofluorescent staining confirmed that hDPSCs express C5L2. Furthermore, we determined by real-time polymerase chain reaction that the expression of C5L2 is highly modulated in human dental pulp stem cells (hDPSCs) undergoing odontoblastic differentiation. Moreover, we showed that this odontogenesis-regulated expression of C5L2 is specifically potentiated by the proinflammatory cytokine TNFα. Using a C5L2-siRNA silencing strategy, we provide direct evidence that C5L2 constitutes a negative regulator of the dentinogenic marker DMP1 (dentin matrix protein 1) expression by hDPSCs. Our findings suggest a direct correlation between the odontoblastic differentiation and the level of C5L2 expression in hDPSCs and identify C5L2 as a negative regulator of DMP1 expression by hDPSCs during the odontoblastic differentiation and inflammation processes. This work is the first to demonstrate the involvement of C5L2 in the biological function of stem cells, provides an important knowledge in understanding odontoblastic differentiation of dental pulp stem cells, and may be useful in future dentin-pulp engineering strategies.

Abstract
BACKGROUND Nausea is more difficult to control than vomiting in chemotherapy. We therefore analyzed the efficacy of a strong supportive treatment with aprepitant, palonosetron, and dexamethasone against nausea for various moderately emetogenic chemotherapy (MEC). METHODS A total of 312 cases treated by palonosetron with or without aprepitant receiving MEC regimens using oxaliplatin, carboplatin, and irinotecan from 2014 to 2016 in our outpatient center for digestive organ cancers, lung cancers, and gynecological cancers were analyzed. Through propensity score matching analysis, cases were divided into 97 cases receiving 2 drugs (palonosetron+dexamethasone) and 97 receiving 3 drugs (aprepitant+palonosetron+dexamethasone). We examined the control rates of nausea for the first two consecutive courses in the both groups. Additionally, risk factors for acute and delayed nausea were analyzed using a multivariate analysis among overall 312 cases. RESULTS The control rates of nausea in the two- and the three-drug groups were as follows: acute, 92.8 and 95.9% (p = 0.35); and delayed, 83.5 and 81.4% (p = 0.85), although the control rates of vomiting exceeded 95% in both groups. A multivariate analysis showed that significant risk factors for acute nausea (odds ratio, 95% confidence interval) were elevation of serum creatinine (12.601, 2.437-65.157), general fatigue (3.728, 1.098-12.661), and performance status (PS) 2 (19.829, 3.200-122.865). The significant risk factors for delayed nausea were elevation of alanine aminotransferase (2.397, 1.153-4.984), general fatigue (2.652, 1.380-5.097), and PS 2 (5.748, 1.392-23.740). CONCLUSIONS The control for nausea in MEC was insufficient even with palonosetron and aprepitant, and we should pay attention to risk factors for preventing nausea.

Abstract
PURPOSE The objective of this study was to evaluate the efficacy, defined by the 3-year tumor recurrence-free survival rate, of intravesical chemotherapy using pirarubicin (THP) in patients with low or intermediate-risk nonmuscle-invasive bladder cancer (NMIBC). PATIENTS AND METHODS Between October 2010 and January 2015, 206 patients were enrolled, and finally 113 were randomized to receive either a single immediate postoperative intravesical instillation of THP (30 mg) (Group A), or 8 additional weekly intravesical instillations of THP (30 mg) after a single postoperative instillation (Group B). The patients were examined by performing cystoscopy and urine cytology every 3 months after transurethral resection to determine bladder tumor recurrence. The primary endpoint was 3-year-recurrence-free survival rate. RESULTS All 113 patients were bacillus Calmette-Guérin (BCG)-naïve. The 3-year recurrence free survival rate was 63.7% for Group A and 85.3% for Group B (log-rank test, P = .0070). In patients with intermediate recurrence risk, the 3-year recurrence-free survival rate was 63.4% in Group A and 86.1% in Group B (log-rank test, P = .0036). Cox regression analysis revealed that only additional instillation of THP was a significant independent factor for recurrence-free rate in patients with intermediate risk. No patient with progression was noted during this period. Frequent adverse effects (AEs) were frequent urination and micturition pain, and no severe AEs (Grade 3 or more) occurred. CONCLUSION Additional instillation of THP (30 mg) weekly for 8 weeks reduced the risk of tumor recurrence without severe AEs in BCG-naïve NMIBC patients with intermediate risk.

Abstract
Cholinergic syndrome is an acute adverse reaction associated with irinotecan. Development of cholinergic syndrome can be ameliorated or prevented by administering various anticholinergics, including atropine sulfate or scopolamine butylbromide. Although many of the side effects are transient and non-life-threatening, their onset is painful and can lower a patient's quality of life (QoL). This retrospective study was performed to identify predictive factors of the development of irinotecan-related cholinergic syndrome in order to develop future strategies for improving the QoL of patients undergoing chemotherapy. We enrolled 150 cancer patients who underwent chemotherapy, which included irinotecan, in our outpatient chemotherapy center between October 2014 and January 2017. For regression analysis, variables related to the development of irinotecan-related cholinergic syndrome were extracted from the patient's clinical records. The degree of cholinergic syndrome was classified as follows: grade 0 = not developed; grade 1 = developed but did not require anticholinergic drugs; and grade 2 = developed and required anticholinergic drugs or stopping the chemotherapy due to cholinergic syndrome. Multivariate ordered logistic regression analysis was performed to identify predictive factors for the development of irinotecan-related cholinergic syndrome. Threshold measurements were determined using a receiver operating characteristic analysis (ROC) curve. Significant factors identified for the development of cholinergic syndrome included female sex [odds ratio (OR) 2.183, 95% confidence interval (CI) 1.010-4.717; P = 0.0471] and irinotecan dose (OR 1.014, 95% Cl 1.007-1.021; P = 0.0001). ROC curve analysis of the group likely to develop cholinergic syndrome indicated that the threshold for the irinotecan dose was 175 mg or above (area under the curve = 0.69). In conclusion, female sex and irinotecan dose were identified as significant predictors of the development of cholinergic syndrome.

Abstract
Although pegfilgrastim prophylaxis is expected to maintain the relative dose intensity (RDI) of chemotherapy and improve safety, information is limited. However, the optimal selection of patients eligible for pegfilgrastim prophylaxis is an important issue from a medical economics viewpoint. Therefore, this retrospective study identified factors that could predict these eligible patients to maintain the RDI. The participants included 166 cancer patients undergoing pegfilgrastim prophylaxis combined with chemotherapy in our outpatient chemotherapy center between March 2015 and April 2017. Variables were extracted from clinical records for regression analysis of factors related to maintenance of the RDI. RDI was classified into four categories: 100% = 0, 85% or < 100% = 1, 60% or < 85% = 2, and < 60% = 3. Multivariate ordered logistic regression analysis was performed to identify predictive factors in patients eligible for pegfilgrastim prophylaxis to maintain the RDI. Threshold measures were examined using a receiver operating characteristic (ROC) analysis curve. Age [odds ratio (OR) 1.07, 95% confidence interval (CI) 1.04-1.11; P < 0.0001], anemia (grade) (OR 1.77, 95% CI 1.10-2.84; P = 0.0184), and administration 24-72 h after chemotherapy (OR 0.44, 95% CI 0.22-0.89; P = 0.0224) were factors that significantly correlated with RDI maintenance. ROC curve analysis of the group that failed to maintain the RDI indicated that the threshold for age was 70 years and above, with a sensitivity of 60.0% and specificity of 80.2% (area under the curve: 0.74). In conclusion, younger age, anemia (less), and administration of pegfilgrastim 24-72 h after chemotherapy were significant factors for RDI maintenance.

Abstract
Silencing of androgen receptor (AR)-meditated androgen signaling is thought to be associated with the development of testicular germ cell tumors (TGCTs). However, the role of the androgen/AR signal in TGCT development has not been investigated. In this study, we show that the androgen/AR signal suppressed the cell growth of seminomas (SEs), a type of TGCT, in vitro and in vivo. Growth of SE cells was suppressed by DHT treatment and reduction of androgen levels by surgical castration promoted cancer cell growth in an in vivo xenograft model. Tryptophan hydroxylase 1 (TPH1), the rate limit enzyme in serotonin synthesis, was one of the genes which expression was reduced in DHT-treated SE cells. TPH1 was highly expressed in SE cancer tissues compared with adjacent normal tissues. Activation of androgen/AR signaling in SE cells reduced the expression of TPH1 in SE cells, followed by the reduction of serotonin secretion in cell culture supernatant. These results suggested that silencing of androgen/AR signaling may cause initiation and progression of SE through increase in TPH1 gene expression level.

Abstract
OBJECTIVES To evaluate the impact of morphometric magnetic resonance imaging (MRI) analysis of the prostate zonal anatomy on aging, prostatic hypertrophy and lower urinary tract symptoms in patients from Japan and the USA. SUBJECTS AND METHODS A retrospective analysis of 307 men, including 156 men from Japan and 151 from the USA, who consecutively underwent 3-Tesla MRI and International Prostate Symptom Score (IPSS) assessment because of elevated PSA levels. Using Synapse-Vincent (Fujifilm), the prostatic zones were segmented in each axial step-section of the T2-weighted MRI to reconstruct a three-dimensional model of the prostate, which was used to calculate: zonal volumes (whole-gland prostate, transition zone and peripheral zone volumes); the presumed circle area ratio (PCAR); and PZ thickness. Bivariate associations were quantified using Spearman's rank correlation coefficients. RESULTS The USA subgroup had a greater prostate volume (49 vs 42 mL; P = 0.003) and TZ volume (26 vs 20 mL; P < 0.001) than the Japan subgroup, with no difference in PZ volume (19 vs 20 mL; P = 0.2). There was no age-related increase in PZ volume in either of the subgroups or in the entire cohort (P = 0.9, P = 0.2, P = 0.3, respectively). PZ thickness had a significant negative correlation with PCAR (P < 0.001) and TZ volume (P < 0.001). The greater the increase in the TZ volume with the increase in PCAR, which probably correlates with obstructive pressure, the thinner the PZ became. PCAR had a significant positive correlation with IPSS (P = 0.003) and obstructive symptoms (P = 0.007), while PZ thickness had a significant negative correlation (P = 0.018). CONCLUSIONS No age-related increases and no differences between the Japanese and the US subgroups were found with regard to PZ volume. The more TZ volume increased, the higher the obstructive pressure and the thinner the PZ became; these changes were associated with increased obstructive symptoms. MRI analysis of prostate zonal anatomy enhanced our understanding of age-related changes in morphology and urinary symptoms.

Abstract
Aim: An educational program delivered through e-learning was conducted, focusing on nursing for primary breast cancer patients. This paper investigates the results of the program, clarifying changes in levels of understanding before and after the program, and evaluations of the program by nurses who participated. Methods: The content of the education program, which consisted of 24 lessons, each lasting 15-20 minutes, including case studies, covered concerns raised in questions by patients and families about diagnosis, multimodal treatment and nursing for primary breast cancer. Instructors were Certified Nurses in Breast Cancer Nursing and Certified Nurse Specialists in Cancer Nursing, and PowerPoint presentations with video and audio material were created. A dedicated website was created, and 1417 participants took the on-demand program, which was provided from September 2015 to March 2016. Survey participants were the first 500 nurses registered for the course to respond. A questionnaire created by the researchers was sent by post to respondents. Responses were anonymous with identifying information code, and questionnaires were sent with a return envelope before the program (within 2 weeks of registration) and after the program (within 1 month of the end of the program), with return of the questionnaire signifying consent to participate. The questionnaire comprised 24 items on level of understanding of breast cancer nursing, aligned to program content, plus 11 items on evaluation of the program. Responses were selected from a 5-point scale, where 1 meant “strongly disagree” and 5 meant “strongly agree”. Analysis: Responses were quantified, and mean scores for each item were calculated. In addition, respondents were divided into two groups, namely, those with less than 3 years of breast cancer nursing experience (Group A) and those with 3 or more years' experience (Group B), and were compared using the Mann-Whitney U test. SPSS Statistics V22.0 was used. Ethical considerations: The study went through Research Ethics approval at the researchers' institute of affiliation. Results: A total of 126 people replied to both the pre-program and post-program questionnaire, and of these, the responses of 106 nurses (Group A: 34 nurses, Group B: 72 nurses) who were not qualified as Certified Nurses or Certified Nurse Specialists were used for analysis. Median age was 41.0 years (Group A: 38.5 years, Group B: 42 years), and median number of years of breast cancer nursing was 4.6 years. In terms of program evaluation, “I could study when it was convenient for me” scored 4.63, while “It will be useful for breast cancer nursing from now on” scored 4.57. In terms of comparison of level of understanding before and after the program, understanding improved on all 24 items, and was significant on 19 items. Comparison of the 2 groups showed significant difference on 2 items, “support for changes in body image” and “communication with the patient”, with changes in level of understanding in Group A being greater. Discussion: The study suggests that participants' understanding of breast cancer nursing increased and improvements in clinical practice can be expected through e-learning materials that facilitate effective learning.

Abstract
BACKGROUND Impaired gastric accommodation is one of the major features of functional dyspepsia. Mosapride citrate is a 5-hydroxytryptamine receptor 4 (5-HT4) agonist, which is shown to improve upper abdominal symptoms. However, effect of mosapride on gastric accommodation was not clear. We tested the hypothesis that mosapride enhances the gastric accommodation in normal individuals. METHODS Fourteen male healthy volunteers completed this study. Single administration of mosapride or placebo was performed randomly with more than 1-week interval. Subjects swallowed a triple-lumen polyvinyl tube with a polyethylene bag. The bag was positioned in the proximal stomach and the minimal distending pressure (MDP) was determined. The ramp distension starting from the MDP was then performed and subjects were instructed to score their perception using ordinate scales. Next the intra-bag pressure was set at MDP + 2 mmHg and a liquid meal was administered 30 min later, and the intra-bag volume was recorded for 60 min. We compared the MDP, perception scores, and the intra-bag volume changes by administering placebo and mosapride. KEY RESULTS Minimal distending pressure was not significantly different in subjects receiving mosapride or placebo. Treatment with mosapride had no effect on intra-bag pressures or volumes inducing first sensation or discomfort. Gastric accommodation, expressed as the difference between pre- and postmeal intra-bag volumes, and the percent change of the intra-bag volumes by the meal was significantly enhanced by mosapride compared with placebo. CONCLUSIONS & INFERENCES This is the first study clearly demonstrating that single administration of 5-HT4 agonist can enhance gastric accommodation in humans. (Umin.ac.jp, number UMIN000014063).

Abstract
Motor functions of masticatory organs such as the tongue, lips, cheeks and mandible are known to deteriorate with age, thereby influencing masticatory performance. However, there are few reports on the relationships between tongue and lip functions and masticatory performance. To investigate the relationship between tongue and lip functions and comprehensive masticatory performance, by evaluating crushing, mixing and shearing abilities in young dentate adults. Participants comprised 51 dentate adults with a mean age of 25 years. Maximum tongue pressure and oral diadochokinesis were measured to evaluate tongue and lip functions. A multiple sieving method using peanuts was performed to evaluate crushing ability. A colour-changeable chewing gum was performed to evaluate mixing ability. A test gummy jelly was performed to evaluate shearing ability. The relationship between tongue and lip functions and each masticatory performance was assessed using Pearson's correlation coefficients. In addition, stepwise multiple regression analysis was performed to identify predictors of crushing ability. Crushing ability was significantly correlated with maximum tongue pressure and the number of repetitions of the syllables /pa/, /ta/ and /ka/. Maximum tongue pressure and number of repetitions of the syllable /pa/ were identified as significant predictors for crushing ability. Mixing ability was significantly correlated with the number of repetitions of the syllable /pa/. Shearing ability was not significantly correlated with tongue and lip functions. Masticatory performance during the chewing of brittle foods such as peanuts and solid foods such as chewing gum appears to be correlated with tongue and lip functions.

Abstract
BACKGROUND Conventional systematic biopsy has the shortcoming of sampling error and reveals "no evidence of cancer" with a rate of >50% on active surveillance (AS). The objective of this study is to report our initial experience of applying a 3D-documented biopsy-mapping technology to precisely re-visit geographically documented low-risk prostate cancer and to perform serial analysis of cell-cycle-progression (CCP) gene-panel. METHODS Over a period of 40 months (1/2010-4/2013), the 3D-biopsy-mapping technique, in which the spatial location of biopsy-trajectory was digitally recorded (Koelis), was carried out. A pair of diagnostic (1st-look) and surveillance (2nd-look) biopsy were performed per subject (n = 25), with median interval of 12 months. The documented biopsy-trajectory was used as a target to guide the re-visiting biopsy from the documented cancer focus, as well as the targeted field-biopsy from the un-sampled prostatic field adjacent to negative diagnostic biopsies. The accuracy of re-visiting biopsy and biopsy-derived CCP signatures were evaluated in the pair of the serial biopsy-cores. RESULTS The 1st-look-biopsy revealed a total of 43 cancer lesions (1.7 per patient). The accuracy of re-visiting cancer was 86% (37/43) per lesion, 76% (65/86) per core, and 80% (20/25) per patient. This technology also provided an opportunity for 3D-targeted field-biopsy in order to potentially minimize sampling errors. The CCP gene-panel of the 1st-look (-0.59) versus 2nd-look (-0.37) samples had no significant difference (P = 0.4); which suggested consistency in the molecular signature of the known cancer foci during the short-time interval of median 12 months. Any change in CCP of the same cancer foci would be likely due to change in sampling location from the less to more significant portion in the cancer foci rather than true molecular progression. The study limitations include a small number of the patients. CONCLUSION The 3D-documented biopsy-mapping technology achieved an encouraging re-sampling accuracy of 86% from the known prostate cancer foci, allowing the serial analysis of biopsy-derived CCP signatures.

Abstract
BACKGROUND Corticotropin-releasing hormone (CRH) and its receptor 1 (CRH-R1) play an important role in the colonic response to stress. The central nucleus of the amygdala (CeA) is a major extrahypothalamic site that contains a large number of neurons expressing both CRH and CRH-R1. Here, we verified the hypothesis that CRH in the CeA sensitizes visceral nociception via CRH-R1 with release of noradrenaline, dopamine, and serotonin (5-HT) in the CeA. METHODS In male Wistar rats, visceral sensitivity was quantified by recording the visceromotor response to colorectal distension (CRD) with administration of vehicle, CRH, or the CRH-R1 antagonist CP-154526+ CRH or CRH-R1 antagonist CP-154526 alone into the CeA. Simultaneously, extracellular levels of noradrenaline, dopamine, and 5-HT were measured in the CeA using microdialysis. All data were obtained under restraint conditions. KEY RESULTS Administration of CRH into the CeA significantly increased the number of abdominal muscle contractions in response to CRD. CP-154526 significantly blocked the number of abdominal muscle contractions in response to CRD with the administration of CRH into the CeA. Noradrenaline in the CeA was increased by CRD, further increased by CRH, and inhibited by CRH-R1 antagonist. Dopamine in the CeA was also exaggerated by CRH but was not inhibited by CRH-R1 antagonist. 5-HT in the CeA was unchanged. CONCLUSIONS & INFERENCES These results suggest that CRH in the CeA sensitizes visceral nociception via CRH-R1 with release of noradrenaline.

Abstract
An ECR ion source of Gunma University Heavy Ion Medical Center, so-called KeiGM [M. Muramatsu, A. Kitagawa, Y. Sakamoto, S. Sato, Y. Sato, H. Ogawa, S. Yamada, H. Ogawa, Y. Yoshida, and A. G. Drentje, Rev. Sci. Instrum. 76, 113304 (2005)], has been operated for cancer therapy and physical/biological experiment since 2010. KeiGM produces typically 230 μA of 10 keV/u C(4+) ions from CH4 gases. The vacuum pressure is kept between 1.2 × 10(-4) and 1.7 × 10(-4) Pa so as to suppress the pulse-to-pulse current fluctuation within ±10%. The extraction electrode is cleaned every 6-8 months in order to remove deposited carbon, which increases the leak current and discharge. In order to investigate the possibility of long-term operation without such maintenances, oxygen aging for the cleaning of the extraction electrode has been tested in the test bench. The same-designed ion sources at National Institute of Radiological Sciences and SAGA Heavy Ion Medical Accelerator in Tosu (SAGA-HIMAT) are also operated with stable C(4+) current, which are suitable for the continuous operation for cancer therapy.

The purpose of this study was to determine which factors related to patient self-assessment of dentures are associated with changes in oral health-related quality of life (OHRQoL) among edentulous patients after replacement of complete dentures, and to determine whether masticatory performance as determined using an objective method affects the changes in OHRQoL among edentulous patients. As a preliminary study, the existing questionnaire regarding self-assessment of dentures consisting of 39 question items, measured with a 100-mm visual analogue scale, was analysed by factor analysis. Then a questionnaire, composed of 22 question items, was developed containing six subscales of 'function', 'lower denture', 'upper denture', 'expectation', 'aesthetic and speech' and 'importance'. Final participants in the present study comprised 93 edentulous patients requiring new conventional complete dentures (44 men, 49 women; mean age, 75·0 years). These patients were asked to complete the Japanese version of the Oral Health Impact Profile (OHIP)-EDENT, comprising 19 question items for assessment of OHRQoL in edentulous patients, along with the developed questionnaire regarding self-assessment of dentures. Moreover, masticatory performance was measured using a colour-changeable chewing gum. The questionnaire and measurement were completed twice; before and after replacement of complete dentures. Stepwise multiple regression analysis identified 'lower denture' and 'aesthetic and speech' as significant independent variables besides OHIP-EDENT scores before replacement. These results suggest that sufficient retention of lower dentures and appropriate appearance may lead to improved OHRQoL in edentulous patients.

Abstract
BACKGROUND The 5-HT(4) receptor agonist, mosapride citrate, accelerates gastric emptying. However, the effect of mosapride on colonic function has not been well investigated. We examined whether mosapride changes rectosigmoid motility and perception in patients with irritable bowel syndrome (IBS). METHODS Thirty-seven patients with IBS and 18 healthy subjects were studied. All subjects underwent a rectosigmoid barostat test to measure pain perception to intraluminal distention and resting smooth muscle motility for 20 min in the fasting state. Irritable bowel syndrome patients were then randomly assigned to receive either mosapride 15 mg (n=19) or placebo (n=18) orally with 200 mL water. Rectosigmoid motility and perception were measured again for 60 min following dosing. Rectosigmoid tone and contractility were evaluated in each 10-min period. KEY RESULTS The pain threshold in the patients was significantly lower than that in controls (P<0.01). There were no differences between mosapride and placebo groups in pain threshold, barostat bag volume, or number of contractions at baseline. Mosapride significantly decreased the mean bag volume (P<0.01; group × period interaction by two-way anova) and increased the mean number of contractions (P<0.05) compared with placebo, but did not affect the perception. In IBS patients with constipation (i.e., excluding diarrhea-predominant subjects), mosapride (n=13) increased rectosigmoid tone (P<0.01) and contractions (P<0.05) more than placebo (n=14). CONCLUSIONS & INFERENCES Mosapride stimulates colonic motility without any adverse effect. These findings suggest that mosapride may have the potential to treat IBS patients with constipation and/or functional constipation. Further clinical trials are warranted to confirm the efficacy of this agent.

Abstract
BACKGROUND The herbal medicine rikkunshito is effective for the treatment of gastrointestinal symptoms in patients with functional dyspepsia. Although some basic studies on the effects of rikkunshito have been reported in rats, its effects on human gastric function have not yet been clarified. Psychosocial stress induces visceral hypersensitivity and elements of rikkunshito may reasonably affect or suppress this process. We conducted a study to verify the hypothesis that rikkunshito improves stress-induced gastric hypersensitivity and/or changes in gastric wall tone. METHODS Nine healthy volunteers (five males, four females) participated in the study. The counterbalanced regimen consisted of a 2-week period of oral administration of 7.5 g day(-1) rikkunshito, then a 2-week period without treatment. Fundic sensorimotor function was examined using a gastric barostat twice on the day after each period. Virtual reality stress was imposed during the measurements of gastric tone and electrocardiogram. KEY RESULTS Stress induced a significant increase in heart rate (P = 0.041), gastric volume (P = 0.008), and phasic volume events (P = 0.049) and a decrease in sensory (P = 0.038), discomfort (P = 0.011), and pain (P = 0.041) thresholds of the stomach. Rikkunshito significantly reduced epigastric fullness (P = 0.037) and perceived stress (P = 0.034) following stimulation of the pain threshold, regardless of stress without the drug. Stress reduced gastric volume at the sensory threshold and increased anxiety at the discomfort threshold, and these responses were significantly inhibited by rikkunshito (P = 0.026, P = 0.022, respectively). CONCLUSIONS & INFERENCES These findings suggest that rikkunshito may improve symptoms and impaired gastric accommodation under distention stimuli of the proximal stomach superimposed by stress.

Abstract
The purpose of this study was to investigate the relationship between masticatory performance as determined using a colour-changeable chewing gum and mandibular movements. Subjects comprised 45 fully dentate adults (23 men, 22 women; mean age, 28·1 years). The gum was chewed for a specified number of chewing strokes (20, 40, 60, 80, 120 or 160 strokes) without any instructions as to chewing side. A colourimeter was used to measure L*, a* and b* values (CIE-L*a*b* colour system) for the chewed gum, then the difference between two colours in the CIE-L*a*b* colour space (ΔE) for each number of chewing strokes was calculated according to a formula. Index of masticatory performance (ΔE60) for each subject was obtained using ΔE for 20, 40, 60, 80, 120 and 160 strokes. Mandibular movements were recorded using an opto-electric system with six degrees of freedom. Twelve parameters of mandibular movements relating to amplitude, duration, velocity and angle were computed for each cycle, and mean values for 10 cycles (from cycle 11 to 20) were calculated separately. Stepwise multiple regression analysis identified maximum closing velocity and closing angle as predictors accounting for 18% of the variation in ΔE60. These results suggest that lower angles of approach to intercuspation and faster speed during closing duration are associated with colour changes in the colour-changeable chewing gum.

Abstract
Healthcare workers (HCWs) have an increased incidence of tuberculosis (TB). Periodic and as-needed screenings of HCWs exposed to patients with TB are important. We integrated chest computed tomography (CT) and the QuantiFERON-TB Gold (QFT-G) test into our TB screening programme for HCWs. First, contacts were tested using the QFT-G test. Those positive for the QFT-G test were investigated by CT and classified as having active, latent (LTBI), or old TB. Between April 2005 and April 2010, 11 patients who had not been diagnosed with active TB on admission were found to have the disease. A total of 512 close or high risk contacts were identified, and underwent screening. Out of those, 34 (6.64%) were QFT-G positive, whereas 478 (93.36%) were negative. Of the 34 QFT-G-positive HCWs, four had CT findings compatible with active TB and received multidrug treatment; 24 showed no findings of active TB and received isoniazid for six months. All completed their regimens without any adverse effects. The TB screening programme integrating CT and the QFT-G test was safe and feasible. The efficacy of the programme needs to be confirmed by large scale clinical trials.

Abstract
BACKGROUND The role of histamine in the pathophysiology of irritable bowel syndrome (IBS) is largely unknown. Dysfunction of the autonomic nervous system (ANS) in IBS patients is also not fully confirmed. We hypothesized that blockade of histamine H₁ receptors affects ANS responses differently between IBS subjects and controls. METHODS Subjects were 12 IBS subjects and 12 age- and sex-matched controls. Either 100 μg kg⁻¹ chlorphenamine or the same amount of saline was administered on different days. The rectum was stimulated with electrical currents of 0 mA (sham) or 30 mA. Autonomic nervous system function was measured using mean arterial pressure (MAP), heart rate (HR), high frequency (HF) component of HR variability, low frequency/high frequency ratio (LF/HF ratio) and plasma catecholamines and histamine. Subjective perceived stress during the examination was evaluated on an ordinate scale. KEY RESULTS Mean arterial pressure showed significant effects of diagnosis (P < 0.05) and drug × diagnosis interaction (P < 0.05). The MAP significantly increased after chlorphenamine administration in IBS subjects, but not in controls. Heart rate revealed a significant drug effect (P < 0.001), which decreased after chlorphenamine administration in controls, but not in IBS subjects. Perceived stress significantly increased by rectal stimulation (P < 0.001) and a significant stimulus × diagnosis interaction (P < 0.05) was revealed, indicating greater reduction in IBS subjects by chlorphenamine. CONCLUSION & INFERENCES Sympathetic vasomotor tone in IBS subjects differentially responded on administration of a histamine H₁ antagonist to that of controls. These findings suggest an increased histaminergic activity in IBS subjects.

Abstract
BACKGROUND The profile of intestinal organic acids in irritable bowel syndrome (IBS) and its correlation with gastrointestinal (GI) symptoms are not clear. We hypothesized in this study that altered GI microbiota contribute to IBS symptoms through increased levels of organic acids. METHODS Subjects were 26 IBS patients and 26 age- and sex-matched controls. Fecal samples were collected for microbiota analysis using quantitative real-time polymerase chain reaction and culture methods, and the determination of organic acid levels using high-performance liquid chromatography. Abdominal gas was quantified by image analyses of abdominal X-ray films. Subjects completed a questionnaire for GI symptoms, quality of life (QOL) and negative emotion. KEY RESULTS Irritable bowel syndrome patients showed significantly higher counts of Veillonella (P = 0.046) and Lactobacillus (P = 0.031) than controls. They also expressed significantly higher levels of acetic acid (P = 0.049), propionic acid (P = 0.025) and total organic acids (P = 0.014) than controls. The quantity of bowel gas was not significantly different between controls and IBS patients. Finally, IBS patients with high acetic acid or propionic acid levels presented with significantly worse GI symptoms, QOL and negative emotions than those with low acetic acid or propionic acid levels or controls. CONCLUSIONS & INFERENCES These results support the hypothesis that both fecal microbiota and organic acids are altered in IBS patients. A combination of Veillonella and Lactobacillus is known to produce acetic and propionic acid. High levels of acetic and propionic acid may associate with abdominal symptoms, impaired QOL and negative emotions in IBS.

Abstract
BACKGROUND It has been reported that different brain activation areas are demonstrated during somatosensory and visceral stimulation. However, no study thus far has investigated how activated patterns in the human brain differ during visceral stimulation of different sites of the digestive tracts. The aim of this study was to determine possible site-specific differences in brain responses and perceptions during visceral stimulation of two different sites, the intraluminal distentions of the rectum and descending colon. METHODS Regional cerebral blood flow was assessed in 32 healthy right-handed male subjects using H(2)(15)O positron emission tomography during distention of the rectum (R group, n = 16) or descending colon (DC group, n = 16) at 40 or 20 mmHg. KEY RESULTS R group reported significantly higher scores of abdominal pain (P < 0.05) and urge to defecate (P < 0.001) during the application of stimulus at 40 mmHg compared with DC group but not of abdominal bloating or anxiety. In comparisons of response to the 40-mmHg stimulus, R group showed significantly greater activation in posterior midcingulate cortex (MCC) and right anterior and posterior insula, whereas DC group showed greater activation in subgenual anterior cingulate cortex (ACC), perigenual ACC and left orbitofrontal and superior temporal cortices. CONCLUSIONS & INFERENCES These findings suggest that central projections of painful visceral stimulation from the rectum and descending colon differ in affective, cognitive and nociceptive processing in the brain, which may result in different perceptions of visceral stimulation from different sites.

Abstract
The purpose of this study was to examine whether periodontal treatment incorporating topical antibiotic therapy affects on levels of glycohemoglobin (HbA1c) and serum high-sensitivity C-reactive protein (hs-CRP) in type 2 diabetic patients with periodontal disease, and to explore the relationship between CRP and glycemic control. The whole intervention group (n=32), which underwent anti-infectious periodontal treatment, showed only transient reduction in HbA1c levels without any change in hs-CRP, while the control group (n=17) did not show any changes in HbA1c or hs-CRP. Multiple regression analysis of all subjects revealed that BMI and change in hs-CRP correlated significantly with the reduction of HbA1c at 6 months after the periodontal treatment. Based on the results of multiple regression analysis, the intervention group was subdivided into two groups: those in which hs-CRP levels decreased (CRP-D group), and those in which hs-CRP levels unchanged or increased (CRP-N group) (n=16, respectively), and re-analysis was conducted based upon these subgroups. In the CRP-D subgroup, HbA1c was significantly reduced at the end of the study, but it did not decrease in the CRP-N subgroup. The decrease of HbA1c in the CRP-D subgroup following periodontal treatment was significantly greater than that in the CRP-N subgroup. BMI of each group remained unchanged in this study at the end of the study. Thus, the results suggested that periodontal treatment with topical antibiotics improves HbA1c through reduction of CRP, which may relate to amelioration of insulin resistance, in type 2 diabetic patients with periodontal disease.
