Objective To investigate the changes of renal blood flow parameters in patients with early-stage diabetic nephropathy (DN) treated with Aldose reductase inhibitors (ARI)/Epalrestat. Methods In this prospective, 120 early DN patients aged 20-75 years from the Endocrinology Department of Chengyang District People's Hospital of Qingdao City in 2015 were randomized to intervention group including 68 patients and control group including 52 patients. Two groups of patients separately received Epalrestat and placebo for 3 months. Renal vascular parameters and blood biochemical index were collected at baseline and after intervention. Results After 3 months of supplementation, Epalrestat significantly improved the renal and segmental renal arterial end-diastolic blood flow velocity (EDV) and the interlobular artery peak systolic blood flow velocity (PSV) compared with placebo. While Epalrestat markedly decreased the blood flow resistance index (RI) in interlobular artery compared to placebo. There were no significant changes in fasting blood glucose (FBG), diastolic blood pressure (DBP), systolic blood pressure (SBP), serum urinary acid (SUA), low-density lipoprotein cholesterol (LDL), triacylglycerol (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL), waist circumference (WC) and body mass index (BMI). Conclusion Epalrestat can effectively improve renal arterial blood flow and renal arterial perfusion, which play a protective role in early DN.Purpose To provide a short reflective article discussing the extent to which evidence and research are included within radiography training curricula and whether there is a need for change and greater standardisation. Findings Great steps have been taken to harmonise aspects of radiography training programmes across Europe, however, variations do exist, especially in the areas of clinical practice, training hours and inclusion of specific curriculum topics. Limited evidence exists regarding the inclusion of evidence and research; thus, diversity is likely. The majority of training curricula follow the Bologna cycle and both research and evidence components are likely to be included within teaching and assessment. Wider questions exist regarding maintaining and developing the research and evidence culture within the radiography profession. Education institutions will play an important role in this process. Conclusion Limited evidence exists regarding the inclusion of 'evidence' and 'research' themes within European radiography training curricula. Undoubtedly, there is a need for these themes, but this must be balanced with other demands on the curriculum and how research is likely to evolve within the profession. Implications for practice Greater clarity is needed on how evidence and research are to be included within radiography training curricula. A single model is unlikely to be suitable for all, curricula should focus on the requirements for the newly qualified graduate and the radiography profession as a whole.Recently, a new environmental Francisella strain, Francisella sp. strain W12-1067, has been identified in Germany. This strain is negative for the Francisella pathogenicity island (FPI) but exhibits a putative alternative type VI secretion system. Some known virulence factors of Francisella are present, but the pathogenic capacity of this species is not known yet. In silico genome analysis reveals the presence of a gene cluster tentatively enabling myo-inositol (MI) utilization via a putative inositol oxygenase. Labelling experiments starting from 2H-inositol demonstrate that this gene cluster is indeed involved in the metabolism of MI. We further show that, under in vitro conditions, supply of MI increases growth rates of strain W12-1067 in the absence of glucose and that the metabolism of MI is strongly reduced in a W12-1067 mutant lacking the MI gene cluster. The positive growth effect of MI in the absence of glucose is restored in this mutant strain by introducing the complete MI gene cluster. F. novicida Fx1 is also positive for the MI metabolizing gene cluster and MI again increases growth in a glucose-free medium, in contrast to F. novicida strain U112, which is shown to be a natural mutant of the MI metabolizing gene cluster. Labelling experiments of Francisella sp. strain W12-1067 in medium T containing 13C-glucose, 13C-serine or 13C-glycerol as tracers suggest a bipartite metabolism where glucose is mainly metabolized through glycolysis, but not through the Entner-Doudoroff pathway or the pentose phosphate pathway. Carbon flux from 13C-glycerol and 13C-serine is less active, and label from these tracers is transferred mostly into amino acids, lactate and fatty acids. Together, the metabolism of Francisella sp. strain W12-1067 seems to be more related to the respective one in F. novicida rather than in F. tularensis subsp. holarctica.Background Breast cancer patients with triple-negative or human epidermal growth factor receptor 2 (HER2)-overexpressing phenotypes are recommended to receive chemotherapy for primary tumors greater than 1 cm regardless of nodal status. Muvalaplin compound library inhibitor Neoadjuvant chemotherapy may eradicate subclinical nodal metastases and reduce the extent of axillary surgery performed. Patients and methods A query of the National Cancer Database Participant User File was performed for new cases of female breast cancer from 2012 to 2015. Inclusion criteria were clinical N0 status, receipt of chemotherapy, and receipt of axillary surgery. Exclusions included hormone-positive/HER2-negative tumors and/or distant metastatic disease. Subjects were divided into groups by receipt of neoadjuvant or adjuvant chemotherapy. The primary end point was the extent of axillary surgery, defined as sentinel lymph node biopsy alone or axillary lymph node dissection (ALND). Subgroup analyses were performed on the basis of tumor phenotype and surgery of the primary site. Results A total of 66,771 female patients were included, 15,967 of whom underwent neoadjuvant chemotherapy. ALND rates were higher in patients who received adjuvant chemotherapy (30.6% vs. 28.8%, P less then .001). Among tumor phenotypes, the extent of axillary surgery was reduced most significantly for hormone-negative, HER2-positive disease (30.0% vs. 25.8%, P less then .001). ALND rates were more substantially reduced for patients who underwent mastectomy (41.3% vs. 36.1%, P less then .001) compared to partial mastectomy (21.8% vs. 20.1%, P = .002). Adjuvant chemotherapy was an independent predictor of ALND (odds ratio, 1.26; 95% confidence interval, 1.19-1.33). Conclusion Neoadjuvant chemotherapy reduces the extent of axillary surgery in clinically node-negative, nonluminal breast cancers.
