Recent studies have shown that variability in home blood pressure has an important role in the progression of organ damage. The objective of this study was to investigate the factors that affect variability in home blood pressure in patients with type 2 diabetes. We assessed the relationship between home blood pressure variability, defined as coefficient of variation of mean of triplicate morning and evening blood pressure for 14 consecutive days, and various factors using univariate and multivariate linear regression analyses in 1114 patients with type 2 diabetes. Age (β=0.149, P<0.001), female sex (β=0.125, P=0.010), duration of diabetes mellitus (β=0.103, P=0.005), heart rate (β=0.136, P<0.001), current smoker (β=0.118, P=0.005), white-coat hypertension (β=0.136, P=0.002) and treatment with calcium channel blockers (β=-0.094, P=0.024) were independently associated with coefficient of variation of morning systolic blood pressure. Our findings implicate that factors that might be intervened such as heart rate, smoking status, use of antihypertensive medication in addition to age, sex and duration of diabetes mellitus are associated with variability in home blood pressure in patients with type 2 diabetes. © 2014 Macmillan Publishers Limited.

Background: S100A12 protein is an endogenous receptor ligand for advanced glycation end products. In this study, the plasma S100A12 level was assessed as an independent predictor of mortality, and its utility in clinical settings was examined. Methods. In a previous cross-sectional study, plasma S100A12 levels were measured in 550 maintenance hemodialysis patients to determine the association between S100A12 and the prevalence of cardiovascular diseases (CVD). In this prospective study, the risk of mortality within a two-year period was determined. An integer scoring system was developed to predict mortality on the basis of the plasma S100A12 levels. Results: Higher plasma S100A12 levels (≥18.79 ng/mL) were more closely associated with higher all-cause mortality than lower plasma S100A12 levels (<18.79 ng/mL; P = 0.001). Multivariate Cox proportional hazards analysis revealed higher plasma S100A12 levels [hazard ratio (HR), 2.267; 95% confidence interval (CI), 1.195-4.302; P = 0.012], age ≥65 years (HR, 1.961; 95%CI, 1.017-3.781; P = 0.044), serum albumin levels <3.5 g/dL (HR, 2.198; 95%CI, 1.218-3.968; P = 0.012), and history of CVD (HR, 2.068; 95%CI, 1.146-3.732; P = 0.016) to be independent predictors of two-year all-cause mortality. The integer score was derived by assigning points to these factors and determining total scores. The scoring system revealed trends across increasing scores for predicting the all-cause mortality [c-statistic = 0.730 (0.656-0.804)]. The resulting model demonstrated good discriminative power for distinguishing the validation population of 303 hemodialysis patients [c-statistic = 0.721 (0.627-0.815)]. Conclusion: The results indicate that plasma S100A12 level is an independent predictor for two-year all-cause mortality. A simple integer scoring system was therefore established for predicting mortality on the basis of plasma S100A12 levels. © 2013 Shiotsu et al.; licensee BioMed Central Ltd.

A 75-year-old man, who was on maintenance hemodialysis, underwent a radiotherapy for locally recurrence of rectal cancer. A pain palliation was achieved and serum tumor markers were reduced. However, after six months, a tumor re- growth was detected and sacral pain was increased. Then, a radiofrequency ablation (RFA) was performed repeatedly as a palliative therapy and pain palliation was achieved. RFA is a safe and effective palliative therapy for patients of poor-risk, such as a terminal stage or hemodialysis patient. Furthermore, it is able to perform repeatedly when the response was not satisfactory. However, a Cool-tip electrode could not to be placed because tumors were hardened by radiotherapy and a repeat of RFA. Then a development of novel Cool-tip electrode may be needed.

Traditional anvil graspers cannot delicately handle the anvil head as a result of their unique jaw shape that enhances grip force, and they are not suitable for confined pelvic space. With a manufacturing company, we developed a novel anvil grasper, the evolutional anvil grasper for laparoendoscopic surgery (EAGLE), to ensure more precise and safer anastomosis procedures. The EAGLE has curved blades that create a 6-mm grasping surface that is the same diameter as the anvil stem and is covered with tungsten carbide tips. When using the EAGLE, a surgeon grasps the anvil stem slightly and easily, handles the anvil head and proximal colon, and smoothly sets the anvil to the center rod of the circular stapler. A surgeon can also securely grasp the stem of the anvil, push it into the center rod of the circular stapler and then perform a sequence of actions in anastomosis procedures smoothly and safely. © 2012 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

Purpose: Endoscopic mucosal resection (EMR) of colorectal polyps should be curative and safe. This study aimed to determine the efficacy and safety of colorectal EMR using 0.13 % hyaluronic acid (HA) solution. Methods: This was a single-armed multicenter prospective open trial conducted at 11 Japanese institutions. Lesion characteristics and various measures of clinical outcome, including en bloc resection, histopathologically complete resection, and postoperative bleeding were analyzed for 624 consecutive patients who underwent EMR of colorectal polyps at ≤20 mm in size from August 2010 to September 2011. Results: En bloc and complete resection were achieved in 93.3 and 78.3 % of 624 lesions. The median EMR procedure time was 2.1 ± 1.5 min. The rates of postoperative bleeding and perforation were 1.1 and 0 %. The rate of en bloc resection was higher for polyps at 5-10 mm than for polyps at 11-20 mm (95.1 vs. 85.1 %; P < 0.001) and was higher for protruding polyps than for superficial polyps (94.5 vs. 87.1 %; P < 0.05). The rate of en bloc resection was also higher for polyps in the left-side colon than for those in the right-side colon or rectum (96.7 vs. 91.6 vs. 90.8 %; P < 0.05). Multivariate analysis showed that polyp at 11-20 mm in size and location not on the left-side colon was significantly independent risk factors for failure of en bloc resection. Conclusion: EMR using 0.13 % HA of colorectal polyps less than 20 mm in size had high rates of en bloc and complete resection and few complications. © 2013 Springer-Verlag Berlin Heidelberg.
