1A STUDY OF STRUCTURE AND PROPERTY CHANGES OF BIODEGRADABLE POLYGLYCOLIDE AND POLY(GLYCOLIDE-co-LACTIDE)FIBERS DURING PROCESSING AND IN VITRO DEGRADATION显示文摘Structure and properties of bioabsorbable polyglycolide (PGA) and poly(glycolide-co-lactide) (PGA-co-PLA)fibers were investigated during several industrial processing stages and in vitro degradation by means of wide-angle X-ray diffraction (WAXD), dynamic mechanical analysis (DMA) and mechanical property tests. In the orientation stage, the PGA fibers were found to have higher degrees of crystallinity than corresponding PGA-co-PLA samples produced under similar conditions. In the hot-stretching and post-annealing stages, after fibers were braided, PGA samples were found to gain more crystallinity and higher Tg than PGA-co-PLA samples. The higher crystallinity in PGA fibers resulted in a slower rate of degradation. DMA results showed that a great deal of internal stress that was built during orientation and hot-stretching stages was released in the post-annealing stage for all PGA and PGA-co-PLA samples. During earlier stages ofin vitro degradation, both PGA and PGA-co-PLA samples exhibited the typical cleavage-induced crystallization mechanism. The heat shrinkage in the glass transition area was found to disappear after 6-8 days of degradation for all PGA and PGA-co-PLA samples, indicating the amorphous portions of the polymers lost orientation after a short period in the buffer solution, most likely due to relaxation of the cleaved chains.Bruce X.Fu Benjamin S.Hsiao Gavin Chen Jack Zhou Susan Lin Jenny Yuan Ilya Koyfman Dennis D Jamiolkowski Edward Dormier 2003Chinese Journal of Polymer Science2003,21,2:9
2Recent trends in liver transplantation for alcoholic liver disease in the United States显示文摘AIM To examine temporal changes in the indications for liver transplantation(LT) and characteristics of patients transplanted for alcoholic liver disease(ALD).METHODS We performed a retrospective cohort analysis of trends in the indication for LT using the United Network for Organ Sharing(UNOS) database between 2002 and 2015. Patients were grouped by etiology of the liver disease and characteristics were compared using χ~2 and t-tests. Time series analysis was used identifying any year with a significant change in the number of transplants per year for ALD, and before and after eras were modeled using a general linear model. Subgroup analysis of recipients with ALD was performed by age group, gender, UNOS region and etiology(alcoholic cirrhosis, alcoholic hepatitis and hepatitis C-alcoholic cirrhosis dual listing).RESULTS Of 74216 liver transplant recipients, ALD(n = 9400, 12.7%) was the third leading indication for transplant after hepatitis C and hepatocellular carcinoma. Transplants for ALD, increased from 12.8%(553) in 2002 to 16.5%(1020) in 2015. Time series analysis indicated a significant increase in the number of transplants per year for ALD in 2013(P = 0.03). There were a stable number of transplants per year between 2002 and 2012(linear coefficient 3, 95%CI:-4.6, 11.2) an increase of 177 per year between 2013 and 2015(95%CI: 119, 234). This increase was significant for all age groups except those 71-83 years old, was observed for both genders, and was incompletely explained by a decrease in transplants for hepatitis C and ALD dual listing. All UNOS regions except region 9 saw an increase in the mean number of transplants per year when comparing eras, and this increase was significant in regions 2, 3, 4, 5, 6, 8, 10 and 11.CONCLUSION There has been a dramatic increase in the number of transplants for ALD starting in 2013.Catherine E Kling James D Perkins Robert L Carithers Dennis M Donovan Lena Sibulesky 2017World Journal of Hepatology2017,9,36:6

6Epistaxis in end stage liver disease masquerading as severe upper gastrointestinal hemorrhage显示文摘AIM:To describe the prevalence,diagnosis,treatment,and outcomes of end stage liver disease(ESLD) patients with severe epistaxis thought to be severe upper gastrointestinal hemorrhage(UGIH).METHODS:This observational single center study included all consecutive patients with ESLD and epistaxis identified from consecutive subjects hospitalized with suspected UGIH and prospectively enrolled in our databases of severe UGIH between 1998 and 2011.RESULTS:A total of 1249 patients were registered for severe UGIH in the data basis,461(36.9%) were cirrhotics. Epistaxis rather than UGIH was the bleeding source in 20 patients. All patients had severe coagulopathy. Epistaxis was initially controlled in all cases. Fifteen(75%) subjects required posterior nasal packing and 2(10%) embolization in addition to correction of coagulopathy. Five(25%) patients died in the hospital,12(60%) received orthotopic liver transplantation(OLT),and 3(15%) were discharged without OLT. The mortality rate was 63% in patients without OLT.CONCLUSION:Severe epistaxis in patients with ESLD is(1) a diagnosis of exclusion that requires upper endoscopy to exclude severe UGIH;and(2) associated with a high mortality rate in patients not receiving OLT.Marine Camus Dennis M Jensen Jason D Matthews Gordon V Ohning Thomas O Kovacs Rome Jutabha Kevin A Ghassemi Gustavo A Machicado Gareth S Dulai 2014World Journal of Gastroenterology2014,20,38:3

10Survival after inflammatory bowel disease-associated colorectal cancer in the Colon Cancer Family Registry显示文摘AIM: To investigate the survival of individuals with colorectal cancer (CRC) with inflammatory bowel disease (IBD-associated CRC) compared to that of individuals without IBD diagnosed with CRC. METHODS: Epidemiologic, clinical, and follow-up data were obtained from the Colon Cancer Family Registry (Colon CFR). IBD-associated cases were identified from self-report of physician diagnosis. For a subset of participants, medical records were examined to confirm self-report of IBD. Cox proportional hazards regression was applied to estimate adjusted hazard ratios (aHR) and 95%CI of mortality, comparing IBD-associated to non-IBD-associated CRC, adjusted for age at CRC diagnosis, sex, Colon CFR phase, and number of prior endoscopies. Following imputation to complete CRC stage information, adjustment for CRC stage was examined. RESULTS: A total of 7202 CRC cases, including 250 cases of IBD-associated CRC, were analyzed. Over a twelve year follow-up period following CRC diagnosis, 2013 and 74 deaths occurred among non-IBD associated CRC and IBD-associated CRC patients, respectively. The difference in survival between IBD-associated and non-IBD CRC cases was not statistically significant (aHR = 1.08; 95%CI: 0.85-1.36). However, the assumption of proportional hazards necessary for valid inference from Cox regression was not met over the entire follow-up period, and we therefore limited analyses to within five years after CRC diagnosis when the assumption of proportional hazards was met. Over this period, there was evidence of worse prognosis for IBD-associated CRC (aHR = 1.36; 95%CI: 1.05-1.76). Results were similar when adjusted for CRC stage, or restricted to IBD confirmed in medical records. CONCLUSION: These results support the hypothesis that IBD-associated CRC has a worse prognosis than non-IBD-associated CRC.Scott V Adams Dennis J Ahnen John A Baron Peter T Campbell Steven Gallinger William M Grady Loic LeMarchand Noralane M Lindor John D Potter Polly A Newcomb 2013World Journal of Gastroenterology2013,19,21:2
