AIM To determine the clinical and dietary predictors of common carotid artery intima media thickness(CCA IMT) in a cohort of subjects with type 1 and type 2 diabetes. METHODS Participants with type 1(n = 23) and type 2 diabetes(n = 127) had mean and mean maximum CCA IMT measured using b mode ultrasound. Dietary intake was measured using a food frequency questionnaire. Clinical and dietary predictors of mean and mean maximum CCA IMT were determined using linear regression analysis adjusted for potential confounders. RESULTS The main predictors of mean and mean maximum CCA IMT were age and weight. After multivariate adjustment there were no dietary predictors of CCA IMT. However,in subjects that were not prescribed a lipid lowering medication alcohol consumption was positively associated with CCA IMT after multivariate adjustment. No difference existed in CCA IMT between subjects with type 1 or type 2 diabetes once age was adjusted for. CONCLUSION CCA IMT was predominantly predicted by age and weight in these subjects with diabetes. The finding that CCA IMT was not different between people with type 1 and type 2 diabetes warrants further investigation in a larger cohort.

Thispaper comprises post-hoc analyses investigating the relationship between dairy intake, serum lipid species and vascular health. Central and peripheral blood pressure, carotid femoral pulse wave velocity, augmentation index, serum lipid species and dietary intake were measured at baseline and 3-mo.

Intermittent energy restriction in type 2 diabetes: A short discussion of medication management

引用

World Journal of Diabetes 2016年第20期7卷 627-630页

作者： Sharayah Carter Peter M Clifton jennifer b.keogh School of Pharmacy and Medical Sciences University of South Australia

AIM To discuss type 2 diabetes mellitus(T2DM) medication changes required during the popular 5:2 intermittent energy restriction(IER) diet. METHODS A search was conducted in MEDLINE, EMbASE, AMED, CINAHL and Cochrane library for original research articles investigating the use of very low calorie diets(VLCD) in people with T2 DM. The search terms used included "VLCD" or "very low energy diet" or "very low energy restriction" or "IER" or "intermittent fasting" or "calorie restriction" or "diabetes mellitus type 2" and "type 2 diabetes". Reference lists of selected articles were also screened for relevant publications. Only research articles written in English, which also included an explanation of medication changes were included. A recent pilot trial using the 5:2 IER method, conducted by our research group, will also be *** A total of 8 studies were found that investigated the use of VLCD in T2 DM and discussed medication management. Overall these studies indicate that the use of a VLCD for people with T2 DM usually require the cessation of medication to prevent hypoglycemia. Therefore, the 5:2 IER method will also require medication changes, but as seen in our pilot trial, may not require total cessation of medication, rather a cessation on the 2 IER days only. CONCLUSION Guidelines outlined here can be used in the initial stages of a 2-d IER diet, but extensive blood glucose monitoring is still required to make the necessary individual reductions to medications in response to weight loss.

On the optimization problem of model-based monitoring

引用

Science China(Technological Sciences) 2011年第5期54卷 1095-1106页

作者： L. GINZINGER M. N. SAHINKAYA b. HECKMANN P. keogh H. ULbRICH Department of Mechanical Engineering Faculty of Engineering and Design University of Bath Institute of Applied Mechanics Technische Universitt München

Today there is a big interest in reducing the maintenance costs and in increasing the reliability of machines in continuous operation. Therefore, maintenance on condition is used. State-of-the-art is a trend analysis and a fault prediction made only based on sensor signals and stochastic methods. The identification possibilities of this technique are limited. A new concept for model-based monitoring has been developed for more detailed fault identification. The developed concept determines the condition of a machine after the occurrence of a fault. The concept is based on a simulation including various faults and an optimization tool. The development of a cost function and the optimization is one of the challenges of such a concept. Using an AMb rotor system with an auxiliary bearing, the new concept of model-based monitoring is investigated using experiments and the optimization is discussed in this paper.

Epidemiology of ovarian cancer:a review

引用

Cancer biology & Medicine 2017年第1期14卷 9-32页

作者： brett M.Reid jennifer b.Permuth Thomas A.Sellers Department of Cancer Epidemiology Division of Population SciencesMoffitt Cancer CenterTampa 33612FLUSA

Ovarian cancer(OC) is the seventh most commonly diagnosed cancer among women in the world and the tenth most common in China. Epithelial OC is the most predominant pathologic subtype, with five major histotypes that differ in origination,pathogenesis, molecular alterations, risk factors, and prognosis. Genetic susceptibility is manifested by rare inherited mutations with high to moderate penetrance. Genome-wide association studies have additionally identified 29 common susceptibility alleles for OC, including 14 subtype-specific alleles. Several reproductive and hormonal factors may lower risk, including parity, oral contraceptive use, and lactation, while others such as older age at menopause and hormone replacement therapy confer increased risks. These associations differ by histotype, especially for mucinous OC, likely reflecting differences in etiology. Endometrioid and clear cell OC share a similar, unique pattern of associations with increased risks among women with endometriosis and decreased risks associated with tubal ligation. OC risks associated with other gynecological conditions and procedures, such as hysterectomy,pelvic inflammatory disease, and polycystic ovarian syndrome, are less clear. Other possible risk factors include environmental and lifestyle factors such as asbestos and talc powder exposures, and cigarette smoking. The epidemiology provides clues on etiology,primary prevention, early detection, and possibly even therapeutic strategies.
