Abstract
Clinical trials have revealed that sodium glucose cotransporter 2 (SGLT2) inhibitors suppress the onset of heart failure and cardiovascular death in diabetic patients. On the other hand, few reports have been published concerning such effects of dipeptidyl peptidase-4 (DPP-4) inhibitors. We undertook the present study to evaluate the effects of SGLT2 inhibitors and DPP-4 inhibitors on the advanced glycation end products (AGEs), well known as a risk factor for the development of cardiovascular disorders.Type 2 diabetes mellitus were divided into two groups and treated with either SGLT2 inhibitors or DPP-4 inhibitors for 3 months. Before and after the 3-month treatment period with each drug, the AGEs and diabetes-related parameters were measured. Methylglyoxal-derived hydroimidazolone-1 (MG-H1) was measured as one of the AGEs.In the SGLT2 inhibitor group, both the blood HbA1c and MG-H1 levels decreased significantly after the 3-month treatment period. In the DPP-4 inhibitor group, only the blood HbA1c level decreased significantly, with no significant change of the blood MG-H1 level.SGLT2 inhibitor reduced both the blood levels of HbA1c and AGEs (MG-H1). Considering that the blood levels of AGEs are associated with the risk of heart failure and cardiovascular disorders, the results of the present study suggest that the effect of SGLT2 inhibitors in suppressing cardiovascular death might be mediated by the reduction in the blood levels of AGEs induced by this class of drugs. DPP-4 inhibitors showed no significant effects on the blood levels of AGEs.

Abstract
Background Frailty increases the risk of falling, hospitalization, and premature death, necessitating practical early-detection tools. Objectives To examine the discriminative ability of KinectTM-based stepping parameters for identifying frailty phenotype. Design Population-based cross-sectional study. Setting Eighteen neighborhoods near Tokyo Metropolitan Institute for Geriatrics and Gerontology, Itabashi, Tokyo, Japan. Participants In total, 563 community-dwelling older adults aged ≥75 years without mobility limitations, neurological disease, or dementia were included. Measurements Step number (SN) and knee total movement distance (KMD) during a 20-s stepping test were evaluated using the KinectTM infrared depth sensor. Results The number (%) of participants with frailty were 51 (9.1). The area under the receiver operating characteristic curves (95% confidence interval) of a parameter consisting of SN and KMD for frailty was 0.72 (0.64, 0.79). Conclusions Stepping parameters evaluated using KinectTM provided acceptable ability in identifying frailty phenotype, making it a practical screening tool in primary care and home settings.

Abstract
Selective inhibitors of sodium glucose co-transporter-2 (SGLT2) suppress renal glucose reabsorption and promote urinary glucose excretion, thereby lowering blood glucose. SGLT2 inhibitors have been reported to reduce body weight. However, the mechanism underlying the reduction in the body weight induced by SGLT2 inhibitor treatment remains to be elucidated. In this study, we investigated the effects of SGLT2 inhibitors on the intestinal bacterial flora. A total of 36 Japanese patients with type 2 diabetes mellitus received a SGLT2 inhibitor (luseogliflozin or dapagliflozin) for 3 months, and the prevalences of balance-regulating bacteria and balance-disturbing bacteria in the feces of the patients before and after SGLT2 inhibitor treatment were determined. SGLT2 inhibitor treatment was associated with a significant increase of the overall prevalence of the 12 types of balance-regulating bacteria. In addition, significant increases in the prevalences of the short-chain fatty acid (SCFAs)-producing bacteria among the balance-regulating bacteria were also observed. Individual analyses of the balance-regulating bacteria revealed that the SGLT2 inhibitor treatment was associated with a significant increase in the prevalence of Ruminococci, which are balance-regulating bacteria classified as SCFAs-producing bacteria. However, SGLT2 inhibitor had no effect on the balance-disturbing bacteria. These results suggested that SGLT2 inhibitor treatment was associated with an overall increase in the prevalence of balance-regulating bacteria. Among the balance-regulating bacteria, the prevalences of SCFAs-producing bacteria increased. SCFAs have been reported to prevent obesity. The results of the present study suggest that SGLT2 inhibitors might induce body weight reduction via their actions on the intestinal bacterial flora.

Abstract
BACKGROUND SGLT2 inhibitor enhances not only glucose excretion but also fatty acid utilization. Those facts suggest that SGLT2 inhibitor affects fat accumulation and lipid storage. OBJECTIVE In the present study, we evaluated the effects of dapagliflozin on fatty acid composition and gene expression involved in fatty acid metabolism in rat adipose and liver tissues. METHODS We administered 1 mg/kg/day dapagliflozin for 7 weeks to male high-fat-fed rats (DAPA group), and then weights and 22 fatty acid contents in the epididymal (EPI), mesenteric (MES), retroperitoneal (RET) and subcutaneous (SUB) adipose tissues, and the liver were compared with vehicle-administered control group. RESULTS In the EPI, RET, and SUB in the DAPA group, contents of several fatty acids were lower (P<0.05) than those in the control group while no significant difference was detected in tissue weight. In the MES, not only tissue weight but also wide variety of fatty acid contents including saturated, monounsaturated, and polyunsaturated fatty acids were lower (P<0.05). As for the liver tissue, no significant difference was observed in fatty acid contents between the groups. mRNA expression of Srebp1c in EPI was significantly higher (P<0.05) in the DAPA group than in the control group, while Scd1 expression in the liver was lower (P<0.01). CONCLUSION These results suggest that dapagliflozin might suppress lipid accumulation especially in the MES, and could reduce contents of fatty acids not in the liver but in adipose tissues in high-fat-fed rats. In addition, dapagliflozin could influence mRNA expression involved in lipogenesis in the EPI and liver.

Abstract
To clarify the effects of long-term administration of SGLT2 inhibitor, a hypoglycemic agent, on basal sympathetic nerve activity (SNA) and on SNA under development of insulin resistance, we measured peripheral SNA in response to a glucose load in standard chow- (SCF) and high-fat-fed (HFF) rats treated with or without dapagliflozin for 7 weeks. We conducted an intravenous glucose administration (IVGA), and evaluated SNA microneurographically recorded in the unilateral sciatic nerve. Dapagliflozin did not affect the steady state action potential (AP) rate just before the IVGA (baseline) in both the SCF and HFF rats. After the IVGA, in the SCF rats, the AP rate in dapagliflozin-treated group transiently decreased within 20 min after the IVGA, and was significantly lower (P < 0.05) than non-treated group for 60 min. In the HFF rats, no significant difference was seen in the AP rate between dapagliflozin-treated and non-treated groups. The rate in the dapagliflozin-treated group after the IVGA was significantly lower (P < 0.05) than the baseline whereas such difference was not found in the non-treated group. In conclusion, dapagliflozin attenuate SNA in response to glucose load, and that the SNA response is different between standard chow-fed- and high-fat-fed rats.

Abstract
Background Obese patients with type 2 diabetes mellitus often develop obstructive sleep apnea syndrome (OSAS). In this study, continuous positive airway pressure (CPAP) was initiated in Japanese patients with type 2 diabetes mellitus who developed OSAS during treatment with a sodium-glucose cotransporter 2 (SGLT2) inhibitor, and the effect of the SGLT2 inhibitor therapy on the patients was investigated. Methods The study was conducted in outpatients with type 2 diabetes mellitus with serum hemoglobin A1c (HbA1c) values of ≥ 6.5% who developed OSAS. The patients were divided into two groups according to whether they were receiving treatment with an SGLT2 inhibitor or with other oral hypoglycemic agents: the SGLT2 inhibitor group (n = 9) and non-SGLT2 inhibitor group (n = 7). The patients in the former group were under treatment with one of the following three SGLT2 inhibitors: luseogliflozin (2.5 mg/day), dapagliflozin (5 mg/day) and empagliflozin (10 mg/day). The patients took the drugs once daily, before or after breakfast. The patients were initiated on CPAP therapy for OSAS, and their weight, body mass index (BMI), serum HbA1c level, lipid profile, liver function parameters, serum uric acid, and apnea-hypopnea index (AHI) measured before the initiation of CPAP therapy (baseline) were compared with the values measured 3 months after the start of CPAP therapy. Results The AHI decreased significantly after 3 months of CPAP therapy, as compared to that at the baseline, in both the SGLT2 inhibitor and non-SGLT2 inhibitor groups. There was no significant change in the serum HbA1c value after 3 months of CPAP therapy as compared to that at the baseline in either group. The body weight and BMI increased significantly after 3 months of CPAP therapy in the SGLT2 inhibitor group, but not in the non-SGLT2 inhibitor group. Conclusion The body weight and BMI increased significantly after 3 months of CPAP therapy initiated for OSAS in the type 2 diabetic patients who were receiving SGLT2 inhibitor therapy. Thus, when CPAP therapy is adopted for an obese diabetic patient with OSAS, it should be borne in mind that the body weight may increase if the patient is receiving SGLT2 inhibitor treatment.

Abstract
Background Selective sodium-glucose cotransporter 2 inhibitors, known to lower the blood glucose levels by promoting the urinary glucose excretion, can predispose to genitourinary infections. This prospective study investigated the influence of selective sodium-glucose cotransporter 2 inhibitors luseogliflozin on the vaginal flora of the pre- and postmenopausal women with type 2 diabetes mellitus. Methods Twelve premenopausal and 24 postmenopausal female Japanese patients with type 2 diabetes mellitus took luseogliflozin 2.5 mg once daily for 6 months. The intravaginal fungal and bacterial populations, together with the body weight and serum parameters of diabetes mellitus and lipid metabolism were measured before and after the treatment. Results After luseogliflozin treatment, the body weight, body mass index and hemoglobin A1c decreased, and the serum levels of high-density lipoprotein cholesterol increased significantly. Luseogliflozin treatment revealed to increase vaginal colony concentrations of Enterococcus faecalis (P = 0.0077) and E. coli (P = 0.0201) in premenopausal patients, and Enterococcus faecalis (P = 0.0051) and Candida albicans (P = 0.0355) in postmenopausal patients. In both pre- and postmenopausal patients, colony concentrations of Staphylococcus spp. had decreased (P = 0.0261 and P = 0.0161). Conclusions Treatment with selective sodium-glucose cotransporter 2 inhibitors luseogliflozin was associated with changes of the vaginal flora. These findings provide basic data on the increased susceptibility to genital infections during luseogliflozin treatment.

Abstract
OBJECTIVE The combination therapy of HMG-CoA reductase inhibitors (statins), which are anti-hyperlipidemic agents, and fibrates may increase the risk of hepatic dysfunction and myopathy, therefore, this combination required careful administration for patients. In the present study, the effects of combination therapy of pemafibrate, a novel fibrate, and statins, was evaluated. METHODS Pemafibrate was administered for 6 months as an add-on to statin therapy in 27 type 2 diabetes patients with dyslipidemia already receiving statins for 6 months (combination group), and the efficacy and safety of the combination therapy in comparison with a pemafibrate monotherapy group was examined. RESULTS In the combination group, a decrease in serum total cholesterol levels was observed after 6 months of pemafibrate treatment compared to baseline, along with an increase in HDL-cholesterol. While serum triglyceride level was reduced, HbA1c level was elevated in both the groups. Serum creatinine kinase level, which is an indicator of myopathy, was lowered in the combination group. In addition, a decrease in γ-glutamyl transpeptidase, a parameter of hepatic dysfunction, was observed in the combination group. CONCLUSION The statin-pemafibrate combination therapy in type 2 diabetes patients with dyslipidemia improved lipid metabolism safely without increasing the risk of hepatic dysfunction and myopathy.

Abstract
AIM Precise biomarkers for predicting prognosis could help to identify high-risk Crohn's disease (CD) patients to facilitate better follow-up during the postoperative course. In this study, the primary aim is the identification of the most reliable nutrition marker that predicts surgical relapse in CD patients. METHOD We first evaluated the predictive value of various nutrition markers for postoperative surgical relapse in CD patients and identified the advanced lung cancer inflammation index (ALI) as a promising biomarker. Then, we assessed the clinical significance of preoperative ALI in CD patients using two cohorts. RESULTS Preoperative ALI showed the highest correlation with reoperation rate compared with other nutritional parameters in CD patients receiving surgical resection (sensitivity 53%, specificity 86%, area under the curve 0.71). Lower levels of preoperative ALI were significantly correlated with the presence of perianal disease. A lower level of preoperative ALI was an independent prognostic factor for reoperation rate after an intestinal resection (hazard ratio 3.37, 95% CI 1.38-10.12, P = 0.006), and the prognostic impact of preoperative ALI was successfully validated in an independent cohort using the same cut-off value. CONCLUSION Preoperative ALI might be useful for postoperative management of CD patients.

Abstract
We conducted this study to determine whether additional administration sodium-glucose co-transporter 2 (SGLT2) inhibitor might provide further improvement of glycemic control and also to explore any advantages in Japanese type 2 diabetes patients showing relatively good glycemic control under treatment dipeptidyl peptidase-4 (DPP-4) inhibitors. We divided the patients in two groups, MT group and CT group. The MT group were continued on the DPP-4 inhibitor treatment for 6-months, and CT group were additionally administered an SGLT2 inhibitor treatment for 6-months. The MT group showed a significant decrease of hemoglobin A1c (HbA1c), but a significant increase of body weight, body mass index and serum uric acid, compared to the baseline values, while the CT group showed a significant decrease of HbA1c, body weight, BMI, and serum uric acid, and also a significant increase of serum HDL-cholesterol and decrease of serum triglyceride levels. Furthermore, this group showed a significant decrease of serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma-glutamyl transpeptidase (γ-GTP), which are markers of liver function. These results suggest that the combination therapy is useful, in particular, for the treatment of type 2 diabetes mellitus patients with hyperlipidemia and liver dysfunction. Among the SGLT2 inhibitors added to the DPP-4 inhibitor treatment, the decreases of serum levels of AST, ALT and γ-GTP were particularly significant in the group receiving luseogliflozin, suggesting that the combination of a DPP-4 inhibitor with luseogliflozin is particularly effective for the treatment of type 2 diabetes mellitus patients with liver dysfunction.

Abstract
BACKGROUND With increasing interest in addressing quality of life of older individuals, tests such as the Functional Independence Measure (FIM) are widely used measures of infirmity and burden of care. However, these scales are largely qualitative and especially problematic when assessing movement-based tasks. While effective, reliable analysis of human movement is technically complicated and expensive; an infrared depth sensor is potentially a low-cost, portable devise which may provide a quantitative aspect to clinical testing. OBJECTIVE to assess the utility of the KinectTM sensor in providing an objective evaluation of human movement using an oft measured ADL (chair stand). DESIGN Cross-sectional study. SETTING Community, geriatric day-care center in Japan. PARTICIPANTS Men (n=136) and women (n=266) between 50 and 93 years of age, consisting of healthy (HE; n=312) and physically frail (FR; n= 90) individuals. MEASUREMENTS Subjects completed two trials of the chair stand, conducted without assistance. Trials were timed and recorded with KinectTM v2. Coronal plane angle (CPA) was determined by a line transecting the shoulder-center and waist relative to the vertical axis and was used to assess quality of the chair stand movement pattern. RESULTS Age, height, and body mass were not different between groups. CPA was significantly greater in FR (29.3 ± 8.3°) than HE (19.5 ± 6.5°). CPA and age were significantly related (r=0.148, p<0.01). An optimal threshold for CPA identifying frailty was determined by a receiver-operator characteristic curve with a CPA of 23.1° providing the greatest combination of sensitivity (79%) and specificity (73%). CONCLUSION During the chair stand, frail older adults adopted a forward lean position (increased CPA) compared to healthy older adults. This compensatory posture appears to facilitate torso rotation while reducing lower-limb muscular effort during standing. As such, CPA serves as an indicator of reduced lower-body function in older, frail adults.

Abstract
SummaryPlatelet aggregation was studied in 24 patients in the chronic stage of ischemic cerebrovascular disease (CVD), with cerebral affluent and effluent blood, i.e., carotid arterial and internal jugular venous blood, and also with peripheral venous blood. Aggregation tests were performed at various final concentrations of sodium arachidonate (A.A.) and ADP. In 17 patients, not taking aspirin, platelet aggregability in jugular venous blood was significantly accentuated compared with that in arterial and peripheral venous blood. This tendency was more marked in the patients with cerebral artery stenosis and/or occlusion than in those with normal cerebral angiogram. In 7 patients taking 500 mg or more oral aspirin, aggregation differences across the brain were not observed and A.A. aggregation and the second phase of ADP aggregation were completely suppressed. These results suggest that a prophylactic administration of aspirin may be beneficial for patients in chronic stage of CVD.

Abstract
We conducted this study to determine whether additional administration of a dipeptidyl peptidase-4 (DPP-4) inhibitor might provide further improvement of the glycemic control in Japanese type 2 diabetes patients showing relatively good glycemic control under treatment with a sodium glucose co-transporter 2 (SGLT2) inhibitor. Five SGLT2 inhibitor (luseogliflozin, dapagliflozin, tofogliflozin, empagliflozin and canagliflozin) preparations and five DPP-4 inhibitor (sitagliptin, vildagliptin, alogliptin, anagliptin and linagliptin) preparations were used. The results showed that monotherapy with SGLT2 inhibitor produced significant decreases of the body weight and BMI, hemoglobin A1c (HbA1c) also decreased, but not to a significant extent. However, decreases of the serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), γ-glutamyltransferase (γ-GTP) and uric acid were observed in this group. On the other hand, in type 2 diabetes patients treated concomitantly with a DPP-4 inhibitor and SGLT2 inhibitor, significant decrease of the HbA1c was observed, indicating the favorable effect of the concomitant therapy. The body weight and BMI decreased. As for the serum lipid profile, elevation of the serum HDL-cholesterol (HDL-C) was observed. Furthermore, AST, ALT, γ-GTP and uric acid decreased in the combined treatment group. Then, the therapeutic responses to concurrent administration with SGLT2 inhibitor of each of the 5 individual DPP-4 inhibitors used in this study were analyzed. The results showed that concomitant administration of sitagliptin, a DPP-4 inhibitor, with the SGLT2 inhibitor yielded the best results in terms of the lowering of the HbA1c and improvement of the serum lipid profile.

Abstract
In patients with type 2 diabetes mellitus who show suboptimal blood glucose control under insulin therapy alone, concomitant treatment with an additional hypoglycemic agent that differs in its mechanism of action from insulin may be considered. We conducted this clinical trial to explore whether further control of increased blood glucose level can be achieved with concomitant use of sodium glucose co-transporter 2 (SGLT2) inhibitor as concomitant with other hypoglycemic therapy, as compared to SGLT2 inhibitor monotherapy, in patients with type 2 diabetes mellitus showing decrease in blood glucose level but less than the effect of insulin monotherapy and there was no significant differences. In the SGLT2 inhibitor monotherapy group, decreases of the serum hemoglobin A1c (HbA1c) level, body weight, body mass index (BMI) and serum triglyceride, and elevation of the serum high density lipoprotein cholesterol concentration were observed as compared to the baseline values. In the type 2 diabetic patients under insulin therapy who received combined insulin plus SGLT2 inhibitor therapy, however decreases in the body weight and BMI, with only a tendency towards decrease of the serum HbA1c value, not reaching statistical significance, were observed. The combined therapy group also showed no appreciable changes of the serum triglyceride level, while the serum adiponectin level increased. The present study data indicate that combined insulin plus SGLT2 inhibitor treatment failed to afford any further improvement of the blood glucose control, as compared to SGLT2 monotherapy, in Japanese type 2 diabetic patients.

Abstract
Background 8q24.21 is a frequently amplified genomic region in colorectal cancer (CRC). This region is often referred to as a 'gene desert' due to lack of any important protein-coding genes, highlighting the potential role of noncoding RNAs, including long noncoding RNAs (lncRNAs) located around the proto-oncogene MYC. In this study, we have firstly evaluated the clinical significance of altered expression of lncRNAs mapped to this genomic locus in CRC. Patients and methods A total of 300 tissues, including 280 CRC and 20 adjacent normal mucosa specimens were evaluated for the expression of 12 lncRNAs using qRT-PCR assays. We analyzed the associations between lncRNA expression and various clinicopathological features, as well as with recurrence free survival (RFS) and overall survival (OS) in two independent cohorts. Results The expression of CCAT1, CCAT1-L, CCAT2, PVT1, and CASC19 were elevated in cancer tissues (P = 0.039, <0.001, 0.018, <0.001, 0.002, respectively). Among these, high expression of CCAT1 and CCAT2 was significantly associated with poor RFS (P = 0.049 and 0.022, respectively) and OS (P = 0.028 and 0.015, respectively). These results were validated in an independent patient cohort, in which combined expression of CCAT1 and CCAT2 expression was significantly associated with a poor RFS (HR:2.60, 95% confidence interval [CI]: 1.04-6.06, P = 0.042) and a poor OS (HR:8.38, 95%CI: 2.68-37.0, P < 0.001). We established a RFS prediction model which revealed that combined expression of CCAT1, CCAT2, and carcinoembryonic antigen was a significant determinant for efficiently predicting RFS in stage II (P = 0.034) and stage III (P = 0.001) CRC patients. Conclusions Several lncRNAs located in 8q24.21 locus are highly over-expressed in CRC. High expression of CCAT1 and CCAT2 significantly associates with poor RFS and OS. The expression of these two lncRNAs independently, or in combination, serves as important prognostic biomarkers in CRC.

Abstract
BACKGROUND Open total gastrectomy carries a high risk of surgical-site infection (SSI). This study evaluated the non-inferiority of antimicrobial prophylaxis for 24 compared with 72 h after open total gastrectomy. METHODS An open-label, randomized, non-inferiority study was conducted at 57 institutions in Japan. Eligible patients were those who underwent open total gastrectomy for gastric cancer. Patients were assigned randomly to continued use of β-lactamase inhibitor for either 24 or 72 h after surgery. The primary endpoint was the incidence of SSI, with non-inferiority based on a margin of 9 percentage points and a 90 per cent c.i. The secondary endpoint was the incidence of remote infection. RESULTS A total of 464 patients (24 h prophylaxis, 228; 72 h prophylaxis, 236) were analysed. SSI occurred in 20 patients (8·8 per cent) in the 24-h prophylaxis group and 26 (11·0 per cent) in the 72-h group (absolute difference -2·2 (90 per cent c.i. -6·8 to 2·4) per cent; P < 0·001 for non-inferiority). However, the incidence of remote infection was significantly higher in the 24-h prophylaxis group. CONCLUSION Antimicrobial prophylaxis for 24 h after total gastrectomy is not inferior to 72 h prophylaxis for prevention of SSI. Shortened antimicrobial prophylaxis might increase the incidence of remote infection. Registration number: UMIN000001062 ( http://www.umin.ac.jp).

Abstract
BACKGROUND Circulating microRNAs (miRNAs) are attracting major interest as potential non-invasive biomarkers for colorectal cancer (CRC). This study aimed to identify a novel serum miRNA biomarker for the early detection and/or evaluating prognosis of CRC patients. PATIENTS AND METHODS Comprehensive miRNA array analysis was carried out using serum samples from patients with colorectal neoplasia and healthy controls. Next, to verify whether the candidate miRNA possessed a secretory potential, we screened miRNA expression levels in culture medium from 2 CRC cell lines, followed by serum analysis from 12 stage IV CRC, 12 adenoma, and 12 control subjects. Thereafter, we validated expression of candidate miRNAs in 179 primary CRC tissues, as well as serum samples from an independent cohort of 211 CRCs, 56 adenomas, and 57 control subjects. RESULTS Through microarray analysis, we identified significantly higher levels of miRNA-1290 (miR-1290) in serum from patients with colorectal adenomas and cancers. We verified miR-1290 overexpression in serum of CRC patients in a training cohort. In the validation cohort, serum miR-1290 levels were significantly up-regulated in patients with colorectal adenomas (P < 0.0001) and cancers (P < 0.0001). Serum miR-1290 levels could robustly distinguish adenoma [area under the curve (AUC) = 0.718] and CRC patients (AUC = 0.830) from normal subjects. High miR-1290 expression in serum and tissue was significantly associated with tumor aggressiveness and poor prognosis. Moreover, serum miR-1290 levels were an independent prognostic factor [hazard ratio (HR) = 4.51; 95% confidence interval (CI) = 1.23-23.69; P = 0.0096] and an independent predictor for tumor recurrence (hazard ratio = 3.92; 95% confidence interval = 1.11-25.14; P = 0.032) in CRC. CONCLUSIONS Serum miR-1290 is a novel biomarker for early detection, recurrence, and prognosis in CRC.

Abstract
It was reported that adipocyte size is potentially correlated in part to amount of long chain polyunsaturated fatty acids (PUFAs) and insulin resistance because several long chain PUFAs can be ligands of peroxisome proliferator-activated receptors (PPARs). In our previous study, marked reduction of PUFAs was observed in insulin-resistant high-fat fed rats, which may indicate that PUFAs are consumed to improve insulin resistance. Although PPARγ agonist, well known as an insulin sensitizer, proliferates small adipocytes, the effects of PPARγ agonist on FA composition in adipose tissue have not been clarified yet. In the present study, we administered pioglitazone, a PPARγ agonist, to high-fat fed rats, and measured their FA composition of triglyceride fraction in adipose tissue and adipocyte diameters in pioglitazone-treated (PIO) and non-treated (control) rats. Insulin sensitivity was obtained with hyperinsulinemic euglycemic clamp. Average adipocyte diameter in the PIO group were smaller than that in the control one without change in tissue weight. In monounsaturated FAs (MUFAs), 14:1n-5, 16:1n-7, and 18:1n-9 contents in the PIO group were lower than those, respectively, in the control group. In contrast, 22:6n-3, 20:3n-6, 20:4n-6, and 22:4n-6 contents in the PIO group were higher than those, respectively, in the control group. Insulin sensitivity was higher in the PIO group than in the control one. These findings suggest that PPARγ activation lowered MUFAs whereas suppressed most of C20 or C22 PUFAs reduction, and that the change of fatty acid composition may be relevant with increase in small adipocytes.

Abstract
Aim The aim of this study was to examine the challenges of self-management of diabetes comparing gender. Methods Sixty-four women and 129 men (mean age 63 vs. 60 years) with diabetes mellitus (DM) were interviewed using 12 categories (classification codes b1300, d240, d570, d620, d845, d920, e410 + e414, e420, e425, e465, e560) related to self-care management selected from 99 categories of the International Classification of Functioning, Disability and Health (ICF) Core Set for DM. In a mixed-methods analysis, interviews were analyzed according to the Grounded Theory approach, and gender effects on ICF categories related to self-care management were investigated using logistic models. Results In quantitative data, compared with men, women tended to experience greater difficulty obtaining foods/ingredients for well-balanced meals to maintain appropriate glucose level (P = 0.004); handling stress and other psychological demands around diabetes treatment (P = 0.034); and social norms, practices, and ideologies that defined an experience of unpleasant treatment after disclosure of DM diagnosis to close family and friends (P = 0.023). Qualitative data shows that women perceived prejudice against people with DM from close family, friends, and neighbors. In contrast, men reported excessive media information on diabetes treatment, which induced prejudice by family members and at the workplace. Conclusions Women were more likely to be sensitive to attention from close family and friends, whereas men were more likely to be occupied by work and daily living concerns. Health professionals should pay attention to such gender differences in a patient-professional relationship.

Abstract
Autonomic neuropathy, one of the serious complications of diabetes, decreases quality of life. Aldose reductase inhibitor (ARI) blocks sorbitol production, and results in prevention of damage of nerve fibers. Beneficial effects of ARI have usually been confirmed through nerve conduction velocity tests in motor and sensory nerves. On the other hand, few reports have dealt with the effects of ARI on the small fiber activity such as sympathetic nerve one. In the present study, we administered eparlestat, ARI orally for 3weeks, to streptozotocin-induced diabetic (STZ+ARI) rats, and then recorded peripheral sympathetic nervous signal detected with microneurographic technique. Action potentials (APs) and bursts of APs were detected from the recorded signal, and their rates and incidences (=rates/heart rate) were compared with those in non-diabetic control (normal) and ARI-untreated streptozotocin-induced diabetic (STZ) rats. While streptozotocin and/or epalrestat did not influence burst parameters in all the three groups, AP parameters in the STZ+ARI and normal groups were higher than those in the STZ group. However, response of AP parameters to the intravenous glucose administration (IVGA) was not large in the STZ+ARI group, similar to that of the STZ group and different from that of the normal group in which AP parameters increased after IVGA. The results suggest that epalrestat may prevent sympathetic nerve activity (SNA) from reduction under hyperglycemic and insulin-depleted conditions, that enhancement of SNA was not induced after IVGA under that condition, and that AP parameters might be useful to assess the degree of neuropathy.

Abstract
To make the treatment for diabetes more effective, we assessed the effects of a data management system for glycemic control. This system enables physicians at distant medical institutions to obtain the fluctuations in blood glucose (BG) measured daily by patients themselves at home and then to give instruction for treatment based on the BG. Use of the system for 2 months resulted in decreases in the hemoglobin A1c (HbA1c) level (from 6.8% ± 0.9% to 6.6% ± 0.8% [ M ± SD], p < .05) and the incidences of preprandial hypoglycemia and postprandial hyperglycemia. These effects can be concluded to have resulted from the fact that physicians become able to give patients appropriate instructions quickly. Also, these effects are considered to have resulted from patient awareness of the importance of self-management of BG.

Abstract
It has been reported that dipeptidyl peptidase-4 (DPP-4) inhibitors improve hemoglobin A1c (HbA1c) levels in diabetic patients and may also improve the serum lipids. However, few studies have examined relationship between the effects of the DPP-4 inhibitor and the pretreatment HbA1c levels in diabetic patients. Furthermore, it has been reported that prolonged treatment with DPP-4 inhibitors may make glycemic control difficult in some patients. In the present study, we investigated (1) the effect of the DPP-4 inhibitor alogliptin on HbA1c, blood glucose (BG), and serum lipid in Japanese patients with type 2 diabetes, (2) the relationship between the HbA1c levels at baseline and the effects of alogliptin, and (3) the effects of switching of the DPP-4 inhibitor to alogliptin after 12 months' administration of sitagliptin on glycemic control and serum lipids. After 6-months' treatment with alogliptin, we found reductions of HbA1c, BG, and serum total cholesterol, and LDL cholesterol levels. Pretreatment level of HbA1c was well correlated with the degree of reduction of both HbA1c and BG levels after the treatment. Also, alogliptin kept levels of HbA1c and BG reduced by sitagliptin for 12 months, and relapsing of these levels and serum lipids were not observed. This study revealed that alogliptin improved HbA1c, BG, and serum lipid profiles in type 2 diabetic patients, and the effect of alogliptin on HbA1c and BG levels was correlated with HbA1c level at pretreatment. Furthermore, long-term treatment with alogliptin did not cause relapsing of glycemic control and serum lipids.

Abstract
Black soybeans (Glycine max (L.) Merr.) are known to be rich in polyphenols, including anthocyanins, and they have been consumed since ancient times for their beneficial effects on health. In addition, it has been reported that black soybean (BS) seed coat may ameliorate obesity and insulin resistance. In the present study, we administered BS extract to type 2 diabetics for 2 months to investigate the effects of BS on glycemic control and lipid metabolism parameters. In addition, we administered BS and antihyperlipidemic agent, fenofibrate, to patients with type 2 diabetes complicated by postprandial hyperlipidemia for 2 months and assessed the combined effects of fenofibrate and BS on serum lipid profile. The results showed that administration of the BS alone had no effect on the blood glucose or lipid levels, but that administration of fenofibrate alone and fenofibrate in combination with the BS significantly lowered their serum triglyceride (TG) level at fasting state, and the percent decrease in the serum TG level after combined administration was significantly higher than in the subjects who received fenofibrate alone. Furthermore, the serum LDL cholesterol concentration, which did not decrease when fenofibrate was administered alone, decreased significantly when the BS and fenofibrate were administered in combination. These results suggest that combined administration of the BS with fenofibrate enhanced the antihyperlipidemic action of fenofibrate, and the results of this study demonstrated the usefulness of the BS in clinical practice.

Abstract
It is known that black soybean (BS) extract, rich in polyphenols, has beneficial effects against obesity, inflammation and insulin resistance. However, detailed effects of BS on lipid metabolism have not been documented well. In the present study, we compared fatty acid composition in visceral and subcutaneous adipose tissues of high-fat fed (HFF) rats and BS administered HFF rats. Black soybean administration for 6 weeks influenced neither body nor adipose tissue weights, blood glucose, plasma insulin levels, or insulin sensitivity. However, BS reduced several saturated (C14:0 and C16:0), monounsaturated (C14:1n-5 and C18:1n-9) and n-6 polyunsaturated (C18:2n-6, C20:3n-6, C20:4n-6 and C22:4n-6) fatty acid contents in subcutaneous fat without any change in n-3 polyunsaturated fatty acid contents. No such effect was observed in fatty acid composition in visceral fat. Long-chain fatty acids are involved in regulation of inflammation. Therefore, those reduced fatty acids may be linked to the effects on suppressing inflammation.

Abstract
BACKGROUND The MYC oncogene has long been established as a central driver in many types of human cancers including colorectal cancer. However, the realization of MYC-targeting therapies remains elusive; as a result, synthetic lethal therapeutic approaches are alternatively being explored. A synthetic lethal therapeutic approach aims to kill MYC-driven tumors by targeting a certain co-regulator on the MYC pathway. PATIENTS AND METHODS We analyzed copy number and expression profiles from 130 colorectal cancer tumors together with publicly available datasets to identify co-regulators on the MYC pathway. Candidates were functionally tested by in vitro assays using colorectal cancer and normal fibroblast cell lines. Additionally, survival analyses were carried out on another 159 colorectal cancer patients and public datasets. RESULTS Our in silico screening identified two MYC co-regulator candidates, AURKA and TPX2, which are interacting mitotic regulators located on chromosome 20q. We found the two candidates showed frequent co-amplification with the MYC locus while expression levels of MYC and the two genes were positively correlated with those of MYC downstream target genes across multiple cancer types. In vitro, the aberrant expression of MYC, AURKA and TPX2 resulted in more aggressive anchorage-independent growth in normal fibroblast cells. Furthermore, knockdown of AURKA or TPX2, or treatment with an AURKA-specific inhibitor effectively suppressed the proliferation of MYC-expressing colorectal cancer cells. Additionally, combined high expression of MYC, AURKA and TPX2 proved to be a poor prognostic indicator of colorectal cancer patient survival. CONCLUSIONS Through bioinformatic analyses and experiments, we proposed TPX2 and AURKA as novel co-regulators on the MYC pathway. Inhibiting the AURKA/TPX2 axis would be a novel synthetic lethal therapeutic approach for MYC-driven cancers.

Abstract
Dipeptidyl peptidase-4 (DPP-4) inhibitors have been reported to improve the glycemic control and blood hemoglobin A1c (HbA1c) concentrations. However, there are few reports as yet suggesting that DPP-4 inhibitors may also improve insulin resistance and the serum lipid profile in the clinical setting. This study was aimed at investigating the effect of 14-week treatment with teneligliptin (20 mg/day) on the homeostasis model assessment ratio (HOMA-R), an indicator of insulin resistance, and serum lipid profile in 9 patients with type 2 diabetes. The treatment produced a significant decrease of the blood glucose and HbA1c concentration (blood glucose: p=0.008; HbA1c: p=0.038), and also improved HOMA-R (p=0.039). Furthermore, the patients showed elevation of the serum HDL-cholesterol level (p=0.032), and a tendency towards reduction of the serum triglyceride level. The results indicate that teneligliptin acts not only to improve the blood glucose control, but also to improve the insulin resistance and serum lipid profile in Japanese type 2 diabetes patients.

Abstract
Background: Tropomyosin-related receptor kinase B (TrkB) promotes proliferation and invasion, relating to poor prognosis of various malignancies. We examined the role of TrkB at the invasive front of gastric cancer (GC) and its association with tumour cell dedifferentiation and tumour budding. Methods: Immunoreactive TrkB was evaluated at the tumour centre and margin using whole-tissue sections of 320 GC patients. Tumour cell dedifferentiation was defined as higher histologic grade at the tumour margin than the surface or tumour centre. Tumour budding was also scored on cytokeratin-stained sections. Results: Sixty-five patients (20%) showed higher TrkB expression at the invasive front (TrkB expression was higher at the tumour margin than tumour centre). It was significantly associated with several aggressive phenotypes in the full cohort (n=320). It showed a prognostic significance in test subgroup (n=98) and was identified as an independent prognostic factor (HR=2.09; 95% CI: 1.26–3.53) by multivariate analysis in validation subgroup (n=222). Twenty-one patients showed tumour cell dedifferentiation. In predominantly differentiated tumour, higher TrkB at the invasive front was significantly associated with tumour budding rather than tumour cell dedifferentiation. Conclusions: Assessment of immunoreactive TrkB at the invasive front by whole-tissue sections provides prognostic information for GC patients.

Abstract
Microneurography is used for the monitor of various peripheral nerve activities. We recently reported that the electrical stimulation of peripheral sympathetic nerve fascicle via the microelectrode, i.e., microstimulation, temporarily reduced the blood glucose level in rats in case that the stimulation intensity was set high enough to induce small muscle contraction. However, the nature of microstimulation has little been clarified yet. Therefore, in the present study, we first detected sympathetic nerve signal microneurographically in the bilateral sciatic nerves of rats, and one of the microelectrodes was used for the microstimulation (0.25 ms-width pulse train at a rate of 1 Hz) while sympathetic nerve activity (SNA) was recorded in the contralateral side as a parameter of systemic sympathetic effects. The SNA, expressed as action potential rate, was transiently increased 150 ms after each stimulation pulse in case that the stimulation intensity was set not less than -0.1 V from the contraction threshold (around 0.32 V). To confirm that the increase was not caused by the activation of low threshold, thick fibers such as motor nerves in the vicinity of the microelectrode tip, next, a bipolar hook electrode, instead of the microelectrode, was then used in the stimulation side. As a result, the above-mentioned, transient increase in SNA was not observed any more in the contralateral side. These results suggest that systemic SNA could be enhanced with lower stimulation intensity than that inducing muscle contraction, and that thicker fibers may little affect the increase in the contralateral SNA.

Abstract
In recent years, the number of patients with type 2 diabetes mellitus caused by insulin resistance has continued to increase in Japan. Insulin resistance is considered to be closely related to the risk of cardiovascular diseases and atherosclerotic diseases, represented by arteriosclerosis obliterans (ASO). Therefore, improvement of insulin resistance is one of the important strategies in the treatment of type 2 diabetes mellitus. At present, α-glucosidase inhibitors, incretin-related drugs, and thiazolidinediones are among the most important oral hypoglycemic drugs used to improve insulin resistance. In this study, the effect of beraprost sodium, a prostaglandin I2 derivative, in the treatment of type 2 diabetes mellitus was investigated. In type 2 diabetic patients with ASO who were under treatment with pioglitazone, additional treatment with beraprost sodium exerted a significant synergistic effect in reducing the serum HbA1c levels as compared to treatment with pioglitazone alone. This result indicates that concomitant administration of pioglitazone and beraprost sodium may be useful in the treatment of diabetes -mellitus.

Abstract
Although streptozotocin-administered (STZ) rats were widely used as an experimental diabetic neuropathy model, sympathetic nerve activity (SNA) in STZ rats has not been microneurographically evaluated so far. In the present study, we investigated the multi-unit, compound sympathetic signal from the sciatic nerve of rats 3 weeks after the administration of streptozotocin, and compared the signal with that of normal (control) rats. After obtaining the sympathetic signal, glucose was intravenously administered to make a transient increase in the blood glucose level to cause SNA change. The sympathetic burst rate did not show any statistical difference between groups at steady state. Even after the glucose administration, it changed little in each group. On the other hand, the firing rate of action potentials (AP-rate) in STZ group was significantly lower than that in control group before glucose administration (p<0.05). In addition, AP-rate was increased in control animals after glucose administration, but not in STZ rats. The results suggest a lower sympathetic tone and poorer response to glucose load under high blood glucose and low plasma insulin condition, and that the AP-rate may be useful for the evaluation of microneurographically measured, peripheral sympathetic activity.

Abstract
Artificial pancreas systems control insulin-mediated glucose uptake. Although these systems are widely used in the clinical setting, they are still fraught with structural and biological problems. The non-insulin mediated glucose uptake (NIMGU) mechanism could be an alternative candidate as a target system for the artificial control of peripheral glucose uptake. Although the sympathetic nervous system is known to be one of the regulators of NIMGU, the effects of peripheral sympathetic activation on glucose uptake have not been well documented. We electrically stimulated a sympathetic nerve fascicle to clarify the possibility of controlling peripheral glucose uptake. A sympathetic signal was microneurographically obtained in the unilateral sciatic nerve in normal (NRML), insulin-resistant high-fat-fed (HFF), and streptozotocin-induced insulin-depleted (STZ) rats, and electrical stimulation was applied via the microelectrode (microstimulation). The microstimulation was also applied to sites other than the sympathetic fascicles in an additional group of normal rats (NSYMP group). The stimulation applied to the sympathetic fibers resulted in an immediate and transient decrease of blood glucose (BG) in the NRML, HFF, and STZ groups, with little change in the plasma insulin. The change in BG level seemed to depend on the basal BG level (NRML < HFF < STZ). In contrast, no reduction in BG was observed in the NSYMP group. These results suggest that microstimulation in the peripheral sympathetic fascicle could enhance glucose uptake in peripheral tissues-independently of insulin function-and show an alternative possibility for controlling glucose uptake.

Abstract
We investigated whether or not preoperative intraluminal brachytherapy (IBT) contributes to a prolongation of the survival after resection of rectal carcinoma. Eighty-five patients with middle and lower rectal carcinoma with penetration into or through the rectal wall were treated with preoperative IBT (30 Gy) and radical resection. The patients were divided into the major effect group (n=59, proportion of remaining viable cells less than 25% of the background stroma) and the minor effect group (n=26, proportion of viable cells over 25%). The major effect group had more down-staged tumors, and a lower rate of positive nodes. Local recurrence rate, distant recurrence rate, and survival rate of the major effect group were 9% (31% in the minor effect group), 15% (55% in minor group) and 74% (36% in minor group), respectively (all parameters: p<0.05). Multivariate analysis indicated that nodal involvement, tumor depth, and proportion of viable cells were the prognostic factors. Preoperative IBT affected not only the tumor morphology but also the prognosis. Our criterion of the proportion of residual viable cells was significantly correlated to the patients' survival. The analyses revealed the positive effects of IBT on the prognosis of rectal cancer.

Abstract
BACKGROUND There is a need for sensitive and specific blood-borne markers for the detection of gastric cancer. Raised serum macrophage inhibitory factor (MIF) levels have been proposed as a marker for gastric cancer diagnosis but, to date, studies have only encompassed patients from high-incidence areas. METHODS We have compared the serum concentration of MIF in a large cohort of UK and Japanese gastric cancer patients, together with appropriate control subjects (age and gender matched). Carcinoembryonic antigen and H. pylori IgG were also measured, as was DJ-1, a novel candidate protein biomarker identified by analysis of gastric cancer cell line secretomes. RESULTS Marked elevations of the serum concentration of MIF and DJ-1 were seen in Japanese patients with gastric cancer compared with Japanese controls, a trend not seen in the UK cohort. These results could not be accounted for by differences in age, disease stage or H. pylori status. CONCLUSION In regions of high, but not low incidence of gastric cancer, both MIF and DJ-1 have elevated serum concentrations in gastric cancer patients, compared with controls. This suggests that differing mechanisms of disease pathogenesis may be at play in high- and low-incidence regions.

Abstract
It is currently believed that metabolic syndrome, in general, and type 2 diabetes mellitus, in particular, depend more on visceral than on subcutaneous adipose tissue. However, the relationship between insulin resistance and fatty acid composition in visceral and subcutaneous adipose tissues remains to be clarified. In the present study, we extracted the triacylglycerol from visceral (epididymis and mesentery) and subcutaneous adipose tissues in normal and insulin-resistant, high-fat-fed (HFF) rats and determined the composition of each fatty acid. The concentrations of palmitoleic, docosapentaenoic, docosahexaenoic, dihomo-γ-linolenic, arachidonic, and docosatetraenoic acids were higher in epididymal adipose tissue than in mesenteric and subcutaneous adipose tissues; but no significant differences were detected between mesenteric and subcutaneous tissues in the normal group or among all the sites in the HFF rats. In the HFF group, stearic and oleic acid concentrations were higher, whereas n-3 and n-6 polyunsaturated ones were lower, than those in the normal group. Palmitoleic acid and some n-3 and n-6 polyunsaturated fatty acid compositions in adipose tissue triacylglycerol depend on anatomical location, which may affect the properties and/or function of adipose tissues. These results at least in part suggest that the properties of adipose tissue are difficult to distinguish based only on their "visceral" or "subcutaneous" sites. In addition, the absence of site dependence and/or difference in balance among saturated, monounsaturated, and polyunsaturated fatty acids may play an important role in the development of insulin resistance in the HFF rats.
