The frequency of radial artery occlusion was compared between patients receiving 4Fr versus 6Fr transradial coronary interventions (TRIs) in an open-label randomized trial (ClinicalTrials.gov identifier: NCT00815997). The primary outcome measure was radial artery occlusion on the day after TRI. The secondary outcome measures were the procedural success, major advanced cardiac events, access site-related complications, procedural times, fluoroscopy times, and contrast dye usage. A total of 160 patients were included. The procedure was successful in 79 of 80 patients (99%) in both groups. Whereas the 4Fr group showed no access site-related complications, the 6Fr developed 5 (6%), including 3 radial artery occlusions and 2 bleedings (1 radial artery perforation and 1 massive hematoma; p = 0.02). Although the radial artery occlusion rate was lower in the 4Fr versus the 6Fr groups, the difference was not significant (0% vs 4%, p = 0.08). The mean hemostasis time was significantly shorter in the 4Fr than in the 6Fr groups (237 ± 105 vs 320 ± 238 minutes, p = 0.007). In conclusion, these findings suggest that 4Fr TRI may become a less invasive alternative to 6Fr TRI in treating coronary artery diseases. © 2014 Elsevier Inc. All rights reserved.

While cancer immunity is involved in tumour progression from the very early stage, no detailed study has been reported on the relationship between early-stage breast cancer and tumour-infiltrating lymphocytes (TILs). We focused on microinvasive carcinoma to investigate the relationship between histological tumour factors and immunity in early breast cancer.Of 2593 resected breast carcinomas, 46 microinvasive carcinomas (1.8%) were included. The relationships between tumour characteristics (invasive form, grade, comedo, subtype) and immunological characteristics (TIL, healing) were examined. The invasive form was divided into cluster-like (ie, invasive foci consisted of a small number of cancer cells) and non-cluster-like (ie, nested and classifiable into particular histological type).Among all cases, 34.8% were grade 1. ER+HER2-, ER+HER2+, ER-HER2+ and ER-HER2- accounted for 58.7%, 8.7%, 28.3% and 4.3%, respectively. Compared with ER+HER2-, ER-HER2+ cases had a significantly stronger association with grade 3 (92.3% vs 0%), comedo (100% vs 55.6%), high TIL (100% vs 29.3%), high CD8+ TIL (92.3% vs 33.3%) and healing (76.9% vs 14.8%) (p<0.001). Compared with non-cluster-like, cluster-like carcinoma showed significantly higher rates of HER2 positivity (69.2% vs 24.2%), high TIL (92.3% vs 42.4%) and high CD8+ TIL (76.9% vs 39.4%) (p<0.01).Our study revealed that microinvasive carcinoma has two progressive pathways; low-grade luminal pathway and high-grade HER2 pathway. HER2-positive cases showed the following unique characteristics: high-grade; comedo, high TIL and CD8+ TIL; healing; cluster-like invasion. These results suggest that the cluster-like invasion might occur because of tumour immunity that leads to disruption of the duct and formation of microinvasive carcinoma in HER2-positive cases.

Quantitative PCR (qPCR) analysis of human T-cell leukemia virus type 1 (HTLV-1) was used to assess the amount of HTLV-1 provirus DNA integrated into the genomic DNA of host blood cells. Accumulating evidence indicates that a high proviral load is one of the risk factors for the development of adult T-cell leukemia/lymphoma and HTLV-1-associated myelopathy/tropical spastic paraparesis. However, interlaboratory variability in qPCR results makes it difficult to assess the differences in reported proviral loads between laboratories. To remedy this situation, we attempted to minimize discrepancies between laboratories through standardization of HTLV-1 qPCR in a collaborative study. TL-Om1 cells that harbor the HTLV-1 provirus were serially diluted with peripheral blood mononuclear cells to prepare a candidate standard. By statistically evaluating the proviral loads of the standard and those determined using in-house qPCR methods at each laboratory, we determined the relative ratios of the measured values in the laboratories to the theoretical values of the TL-Om1 standard. The relative ratios of the laboratories ranged from 0.84 to 4.45. Next, we corrected the proviral loads of the clinical samples from HTLV-1 carriers using the relative ratio. As expected, the overall differences between the laboratories were reduced by half, from 7.4-fold to 3.8-fold on average, after applying the correction. HTLV-1 qPCR can be standardized using TL-Om1 cells as a standard and by determining the relative ratio of the measured to the theoretical standard values in each laboratory.

BACKGROUND The risk of liver cirrhosis is higher among individuals with diabetes mellitus, and a cirrhotic patient with diabetes may have a poorer prognosis after liver transplantation compared to a patient without diabetes. Thus, we evaluated whether fasting plasma glucose prior to receiving a liver transplant was a prognostic factor for post-transplant survival. MATERIAL AND METHODS Ninety-one patients received a living donor liver transplant between November 2005 and December 2012. Patients were considered diabetic if they were prescribed diabetes medications or had impaired glucose tolerance as measured by an oral glucose tolerance test. Each patient was monitored through December 31, 2013, to evaluate prognosis. RESULTS Fasting plasma glucose of at least 100 mg/dL significantly decreased survival following transplant (52% in the high FPG group compared to 78% in the control group, p=0.04), while postprandial hyperglycemia had no effect on survival. Additionally, overall mortality and the incidence of vascular disease were significantly higher among patients with uncontrolled plasma glucose. Impaired fasting plasma glucose was significantly and inversely associated with overall survival in the univariate and multivariate analyses, while creatinine (at least 1 mg/dL) was inversely associated with survival in the univariate analysis. CONCLUSIONS Elevated fasting plasma glucose prior to liver transplantation was inversely associated with post-transplant survival. This effect may be due to underlying microangiopathy as a result of uncontrolled diabetes before transplantation. Our data demonstrated the importance of controlled blood glucose prior to liver transplantation.
