AIM To evaluate the role of albumin at the time of ulcerative colitis(UC) diagnosis in predicting the clinical course of *** Nationwide cohort of patients with newly diagnosed UC in the Veterans Affairs health care system was identified and divided into two categories: hypoalbuminemia(i.e.,≤ 3.5 gm/dl) or normal albumin levels(i.e.,> 3.5 gm/dl) at the time of UC diagnosis. The exposure of interest was presence of hypoalbuminemia defined asalbumin level ≤ 3.5 g/dl at the time of UC diagnosis. Patients were then followed over time to identify the use of ≥ 2 courses of corticosteroids(CS),thiopurines,anti-TNF medications and requirement of colectomy for UC management. RESULTS The eligible study cohort included 802 patients,but 92(11.4%) patients did not have their albumin levels checked at the time of UC diagnosis,and they were excluded. A total of 710 patients,who had albumin levels checked at time of UC diagnosis,were included in our study. Amongst them,536 patients had a normal albumin level and 174 patients had hypoalbuminemia. Patients with hypoalbuminemia at diagnosis had a higher likelihood of ≥ 2 courses of CS use(adjusted HR = 1.7,95%CI: 1.3-2.3),higher likelihood of thiopurine or anti-TNF use(adjusted HR = 1.72,95%CI: 1.23-2.40) than patients with normal albumin level at diagnosis. There was a trend of higher likelihood of colectomy in hypoalbuminemic patients,but it was not statistically significant(Adjusted HR = 1.7,95%CI: 0.90-3.25).CONCLUSION Hypoalbuminemia at disease diagnosis can serve as a prognostic marker to predict the clinical course of UC at the time of diagnosis.

NEURO FUZZY MODEL FOR PREDICTING THE DYNAMIC CHARACTERISTICS OF BEAMS

引用

Acta Mechanica Solida Sinica 2014年第1期27卷 85-96页

作者： Imad O.Bachi nabeel Abdulrazzaq Zeng He Department of Mechanical Engineering Basrah University Department of Mechanics Engineering Huazhong University of Science and Technology Department of Civil Engineering Basrah University

An adaptive neuro-fuzzy inference system （ANFIS） is introduced to predict the dynamic behavior of beams. The effects of axial forces and large displacements are considered in the analysis. A database of tests for the dynamic characteristics of beams is developed from the experimental tests. The responses of nonlinear vibration force for the single and multiple-stepped beams are calculated from the finite element method （FEM）, experimental tests and neuro-fuzzy model for comparison. The neuro-fuzzy model provides a general framework for the combination of neural networks and fuzzy logic. It is more flexible with more options of incorporating the fuzzy nature of the real-world system and is an useful estimation tool for the dynamic characteristics of beams. Therefore, ANFIS can be a useful tool for dynamic behaviour analysis of multiple-stepped beams subjected to axial loads and large displacement.
