Increasing Incidence of Nontuberculous Mycobacteria, Taiwan, 2000â2008
To assess the species distribution and epidemiologic trends of nontuberculous mycobacteria, we examined isolates from patients in Taiwan. During 2000â2008, the proportion increased significantly from 32.3% to 49.8%. Associated disease incidence increased from 2.7 to 10.2 cases per 100,000 patients. Mycobacterium avium complex and M. abscessus were most frequently isolated
A review of application of multi-criteria decision making methods in construction
Construction is an area of study wherein making decisions adequately can mean the difference between success and failure. Moreover, most of the activities belonging to this sector involve taking into account a large number of conflicting aspects, which hinders their management as a whole. Multi-criteria decision making analysis arose to model complex problems like these. This paper reviews the application of 22 different methods belonging to this discipline in various areas of the construction industry clustered in 11 categories. The most significant methods are briefly discussed, pointing out their principal strengths and limitations. Furthermore, the data gathered while performing the paper are statistically analysed to identify different trends concerning the use of these techniques. The review shows their usefulness in characterizing very different decision making environments, highlighting the reliability acquired by the most pragmatic and widespread methods and the emergent tendency to use some of them in combination

Clinical Efficacy and Post-Treatment Seromarkers Associated with the Risk of Hepatocellular Carcinoma among Chronic Hepatitis C Patients
This follow-up study enrolled chronic hepatitis C patients to evaluate the treatment efficacy and to identify post-treatment seromarkers associated with risk of hepatocellular carcinoma (HCC) among patients with a sustained virological response (SVR) or nonsustained virological response (NSVR). A total of 4639 patients who received pegylated interferon and ribavirin during 2004â2013 were followed until December 2014. HCC was confirmed through health examinations and data linkage with a national database. A total of 233 HCC cases were reported after 26,163 person-years of follow-up, indicating an incidence of 8.9 per 1000 person-years: 6.9 for SVR and 21.6 for NSVR per 1000 person-years. The associated risk of HCC in patients with SVR was 0.37 (0.22â0.63) for those without cirrhosis and 0.54 (0.31â0.92) for those with cirrhosis compared with their respective counterparts with NSVR. Among patients with SVR, advanced age, male gender, cirrhosis, decreased platelet count, and increased aspartate aminotransferase and α-fetoprotein levels were associated with HCC (p < 0.001). The treatment of chronic hepatitis C patients before they developed cirrhosis showed a higher efficacy than did the treatment of those who had already developed cirrhosis. Patients with SVR may still have a risk of HCC and need to be regularly monitored
Effects of patient factors on noninvasive liver stiffness measurement using acoustic radiation force impulse elastography in patients with chronic hepatitis C
Gallstones, a cholecystectomy, chronic pancreatitis, and the risk of subsequent pancreatic cancer in diabetic patients: a population- based cohort study
[[abstract]]Background
The causal association between diabetes and pancreatic cancer remains unclear in Asian populations. This study examined whether gallstones, a cholecystectomy, chronic pancreatitis and the treatment of antidiabetic agents affect the risk of subsequent pancreatic cancer for patients with diabetes in a Taiwanese population.
Methods
Using claims data from the universal health insurance program in Taiwan, 449,685 newly diagnosed diabetic cases among insured people from 2000 to 2003 were identified as the case group. The comparison group, matched for gender, age, and the index year of the diabetes cohort, consisted of 325,729 persons without diabetes. Pancreatic cancer incidence was measured in both groups until the end of 2008. Other risk factors associated with this cancer were also measured.
Results
The incidence of pancreatic cancer in the diabetic cohort was 2-fold greater than that in the comparison group (1.46 vs. 0.71 per 10,000 person-years) with an adjusted hazard ratio (HR) of 1.75 [95 % confidence interval (CI) 1.45â2.10]. The risk slightly increased for diabetic patients with gallstones, cholecystitis, and a cholecystectomy (HR 1.92, 95 % CI 1.18â3.11), but greatly increased for those with comorbidity of chronic pancreatitis (HR 22.9, 95 % CI 12.6â41.4). Pancreatic cancer risk also increased significantly for those patients who used more insulin for treating diabetes (OR 2.20, 95 % CI 1.40â3.45).
Conclusion
Our data suggest that the risk of pancreatic cancer is moderately increased in patients with diabetes, especially those using insulin therapy. The risk is greatly increased for diabetic patients with chronic pancreatitis
Splenectomy Correlates With Increased Risk of Pyogenic Liver Abscess: A Nationwide Cohort Study in Taiwan
Objectives: Little is known about the risk of pyogenic liver abscess in patients with splenectomy. We explored the relationship between splenectomy and pyogenic liver abscess in Taiwan.
Methods: We conducted a nationwide cohort analysis using the hospitalization dataset of the Taiwan National Health Insurance Program. We included 17 779 subjects aged 20â84 years who underwent splenectomy in 1998 to 2010 (splenectomy group) and 70 855 randomly selected subjects without splenectomy (non-splenectomy group). Both groups were matched by sex, age, other comorbidities, and hospitalization year of receiving splenectomy. The incidence of pyogenic liver abscess at the end of 2011 was measured. The multivariable Cox proportional hazard regression model was used to estimate the hazard ratios and 95% confidence intervals for pyogenic liver abscess associated with splenectomy and other comorbidities.
Results: The overall incidence rate was 3.75-fold higher in the splenectomy group than that in the non-splenectomy group (2.15 vs 0.57 per 1000 person-years; 95% confidence interval, 3.57â3.94). After controlling for potential confounding factors, the adjusted hazard ratio of pyogenic liver abscess was 3.89 in subjects with splenectomy (95% confidence interval, 3.20â4.72) when compared with subjects without splenectomy. In further analysis, the hazard ratio markedly increased to 14.34 for those with splenectomy and having any of the assessed comorbidities, including alcoholism, biliary stone, chronic kidney disease, chronic liver diseases, and diabetes mellitus (95% confidence interval, 10.61â19.39).
Conclusions: Patients with splenectomy are at an increased risk of developing pyogenic liver abscess, particularly when they have comorbid conditions
