| 1 | Complications and survival in patients undergoing colonic stenting for malignant obstruction显示文摘AIM:To investigate whether predicting patients that might be at a higher risk for complications might serve to improve the selection of patients undergoing colonic stenting.METHODS:A retrospective review of consecutive patients who underwent an attempted self-expandable metal stent(SEMS)insertion for malignant colonic obstruction between November 2006 and March 2013.All patients were either referred for preoperative colonic decompression with the intent of a single surgical procedure,or for palliation of the malignant colorectal obstruction for unresectable cancer.Fisher’s test orχ2test was performed on categorical variables,and the t test for continuous variables.Univariable and multivariable logistic regression were used to examine the association between independent variables and the presence of complications from SEMS insertion.RESULTS:SEMS insertion was attempted in 73 patients.Males comprised 55.71%and the mean age was 67.41±12.41 years.Of these,65.15%underwent subsequent surgery,while 34.85%received SEMS as palliation for advanced disease.Extracolonic tumors were only4.76%.The majority of patients had stageⅣdisease(63.83%),while the remainder had stageⅢ(36.17%).SEMS were successfully inserted in 93.85%(95%CI:87.85%-99.85%).Perforations occurred in 4.10%,SEMS migration in 8.21%,and stent re-occlusion from ingrowth occurred in 2.74%of patients.The mean duration of follow up for the patients was 13.52±17.48 mo(range 0-73 mo).None of the variables:age,sex,time between the onset of symptoms to SEMS insertion,time between SEMS insertion and surgery,length of the stenosis,location of the stenosis,albumin level,or receiving neoadjuvant chemotherapy,could predict the development of complications from either SEMS insertion nor prolonged survival.CONCLUSION:None of the variables could predict the development of complications or survival.Further studies are required to identify patients who would benefit the most from SEMS. | Majid A Almadi Nahla Azzam Othman Alharbi Alabbas H Mohammed Nazia Sadaf Abdulrahman M Aljebreen | 2013 | World Journal of Gastroenterology2013，19，41： | 5 |
| 2 | Clinical epidemiology of ulcerative colitis in Arabs based on the Montréal classification显示文摘AIM:To determine the clinical,epidemiological and phenotypic characteristics of ulcerative colitis(UC)in Saudi Arabia by studying the largest cohort of Arab UC patients.METHODS:Data from UC patients attending gastroenterology clinics in four tertiary care centers in three cities between September 2009 and September 2013were entered into a validated web-based registry,inflammatory bowel disease information system(IBDIS).The IBDIS database covers numerous aspects of inflammatory bowel disease.Patient characteristics,disease phenotype and behavior,age at diagnosis,course of the disease,and extraintestinal manifestations were recorded.RESULTS:Among 394 UC patients,males comprised51.0%and females 49.0%.According to the Montréal classification of age,the major chunk of our patients belonged to the A2 category for age of diagnosis at17-40 years(68.4%),while 24.2%belonged to the A3category for age of diagnosis at>40 years.According to the same classification,a majority of patients had extensive UC(42.7%),35.3%had left-sided colitis and29.2%had only proctitis.Moreover,51.3%were in remission,16.6%had mild UC,23.4%had moderate UC and 8.6%had severe UC.Frequent relapse occurred in17.4%patients,infrequent relapse in 77%and 4.8%had chronic disease.A majority(85.2%)of patients was steroid responsive.With regard to extraintestinal manifestations,arthritis was present in 16.4%,osteopenia in 31.4%,osteoporosis in 17.1%and cutaneous involvement in 7.0%.CONCLUSION:The majority of UC cases were young people(17-40 years),with a male preponderance.While the disease course was found to be similar to that reported in Western countries,more similarities were found with Asian countries with regards to the extent of the disease and response to steroid therapy. | Othman R Alharbi Nahla A Azzam Ahmed S Almalki Majid A Almadi Khalid A Alswat Nazia Sadaf Abdulrahman M Aljebreen | 2014 | World Journal of Gastroenterology2014，20，46： | 2 |

| 12 | Effect of particle size distribution on magnetic behavior of nanoparticles with uniaxial anisotropy显示文摘The effect of particle size distribution on the field and temperature dependence of the hysteresis loop features like coercivity(H_C), remanence(M_R), and blocking temperature(T_B) is simulated for an ensemble of single domain ferromagnetic nanoparticles with uniaxial anisotropy. Our simulations are based on the two-state model for T < T_B and the metropolis Monte-Carlo method for T > T_B. It is found that the increase in the grain size significantly enhances H_C and T_B. The presence of interparticle exchange interaction in the system suppresses H_C but causes MRto significantly increase.Our results show that the parameters associated with the particle size distribution(D_(d,δ)) such as the mean particle size d and standard-deviation δ play key roles in the magnetic behavior of the system. | S Rizwan Ali Farah Naz Humaira Akber M Naeem S Imran Ali S Abdul Basit M Sarim Sadaf Qaseem | 2018 | Chinese Physics B2018，27，9： | 0 |
