05, r = -0.662). Conclusions Patients with ED exhibited prolonged PWD values compared with normal controls. In addition, PWD was found to be associated with severity of the disease. © 2019 The Author(s).Background Contrast-induced nephropathy (CIN) is a leading cause of morbidity and mortality in patients undergoing percutaneous coronary intervention (PCI). Chronic total occlusions (CTO) are frequently observed among patients undergoing coronary angiography. Methods A total of 128 CTO patients were included. Mehran score, lesion characteristics, interventional procedure, serological specimens and devices were recorded. The first group was administered with 1 ml · kg-1 · h-1 saline (0.9% NaCl) infusion that started 12 h before the procedure and continued 12 h post procedure as recommended by the guidelines. The second group was administered with saline infusion of 12 ml · kg-1 · h-1 only during CTO-PCI procedure, which is called as intensive infusion. Results CIN development was similar in two groups (four patients in standard hydration group and five patients in intensive hydration group). The amount of saline was significantly higher in the standard group (1,767 ± 192.2 vs. 1,043.6 ± 375; p  less then  0.001). Patients with higher creatinine levels prior to PCI had a higher rate of CIN development after procedure. Interestingly, age, left ventricular ejection fraction, and diabetes mellitus independently predicted CIN. Conclusion Intensive hydration administration appears to be an effective and cost-effective method in CTO-PCI patients, especially in patients without left ventricular function failure. © 2019 The Author(s).Background Previous studies have demonstrated that homocysteine and asymmetric dimethyl arginine (ADMA) levels were strongly associated with cardiovascular diseases including coronary artery disease. The aim of this study was to investigate the role of plasma homocysteine and ADMA levels in the pathogenesis of coronary slow flow (CSF) phenomenon. Methods Twenty-three patients with CSF and 25 controls with normal coronary flow were included in this study. The quantitative measurement of coronary blood flow was performed using the thrombolysis in myocardial infarction frame count method. Plasma homocysteine and ADMA levels were determined using enzymatic assays from venous blood samples. Results The patients with CSF had significantly higher plasma homocysteine levels than controls (16.2 ± 7.6 vs. 12.2 ± 2.2 μM/L; p = 0.023). The uric acid levels were significantly higher in CSF group than controls (5.4 ± 1.1 vs. 4.6 ± 0.9 mg/dl; p = 0.011). Plasma ADMA levels were also higher in the CSF group; however, this was not statistically significant (0.6 ± 0.1 vs. 0.5 ± 0.2 μM/L; p = 0.475). Alectinib cell line Conclusions Increased homocysteine and uric acid levels may play an important role in the pathogenesis of CSF. Further large scale studies are required to determine the relationship between ADMA levels and CSF. © 2019 The Author(s).Background and aims The aim of this study is to exploratively evaluate the effect of Tsumura Daikenchuto Extract Granules (DKT, TJ-100) on abdominal symptoms, body weight, and nutritional function following colorectal cancer surgery. Methods The subjects included 20 patients for curative resection of colorectal cancer. A TJ-100 administration group (n = 10) and non-administration group (n = 10) were randomized and compared. In the administration group, TJ-100 was administered from 2 days prior to surgery up to 12 weeks following surgery. The endpoints included body weight gain, Gastrointestinal Symptom Rating Scale (GSRS), and blood biochemical factors. For the purpose of observing safety, drug adverse events were evaluated including liver function tests. Results Excluding one patient, we compared 9 cases in the administration group and 10 cases in the non-administration group. No obvious adverse events were observed in any of the cases. In the comparison of body weight gain, the TJ-100 administration group showed significantly higher values at 2, 4, and 12 weeks following the surgery. There was a tendency for lower stable GSRS scores in the administration group overall, with no statistically significant difference. Conclusion It is suggested that TJ-100 can be safely administered in the perioperative period for cases undergoing colorectal cancer surgery, potentially preventing weight loss during the early postoperative period. © 2019 The Author(s).Background Current evidence indicates that vascular calcification plays an essential role in the development of cardiovascular diseases in end-stage renal disease (ESRD) patients. Arterial stiffness is a marker of increased cardiovascular risk in various populations. The aim of this study is to evaluate the elastic properties of ascending aorta in patients with ESRD. Methods This single-center study enrolled 96 patients (45 females, age 57.2 ± 12.8 years) with ESRD and 96 healthy controls (52 females, age 55.3 ± 10.1 years). Aortic pressures and aortic elastic parameters including aortic strain, aortic distensibility, aortic stiffness index, and aortic compliance were calculated using accepted formulae. Results The hemodynamic parameters including aortic pulse pressure, aortic mean pressure, aortic fractional pulse pressure, and aortic pulsatility index were significantly higher in patients with ESRD. Systolic and diastolic aortic diameters were similar between the groups. However, pulsatile aortic diameter change, aortic strain, aortic distensibility, and aortic compliance were significantly lower, whereas aortic stiffness index was significantly higher in ESRD group. Conclusions The results demonstrated that a significant difference was present in terms of aortic blood pressures between patients with ESRD and controls. In addition, the elastic properties of ascending aorta were decreased in patients with ESRD. © 2019 The Author(s).Primary pancreatic hydatid disease is extremely rare. Diagnosis of the disease is difficult because hydatid cysts can be confused with a pseudocyst or neoplastic cystic diseases. Authors report a case of a surgically treated hydatid disease of the uncinate process of pancreas. In a 34-year-old patient with minor symptoms, a cystic disease of the pancreas was accidentally identified. CT scan revealed a multivesicular cystic mass with a maximum of 13-cm diameter and with a calcificated wall. During laparotomy, the uncinate process of pancreas was resecated and the cystic lesion was enucleated. Patient was recovered without complications and recurrence of the disease. There must be a suspicion of hydatid disease when cysts are identified in good conditioned, asymptomatic patients, or in case of wall calcification or multivesicular cysts revealed by radiological images. Surgical procedures are recommended in uncertain diagnoses too, because differentiation preoperatively between cystic pancreatic lesions is often impossible.
