METHODS A longitudinal cohort study was conducted by 14 regional hospitals starting in 2009 through 2016. All adult patients with newly diagnosed HCC either with pathology or imaging criteria were included. Patients were classified as presenting non-alcoholic fatty liver disease(NAFLD) either by histology or clinically, provided that all other etiologies of liver disease were ruled out, fatty liver was present on abdominal ultrasound and alcohol consumption was excluded. Complete follow-up was assessed in all included subjects since the date of HCC diagnosis until death or last medical visit.RESULTS A total of 708 consecutive adults with HCC were included. Six out of 14 hospitals were liver transplant centers(n = 484). The prevalence of diabetes mellitus was 27.7%. Overall, HCV was the main cause of liver disease related with HCC(37%) including cirrhotic and non-cirrhotic patients, followed by alcoholic liver disease 20.8%, NAFLD 11.4%, cryptogenic 9.6%, HBV 5.4% infection, cholestatic disease and autoimmune hepatitis 2.2%, and other causes 9.9%. A 6-fold increase in the percentage corresponding to NAFLDHCC was detected when the starting year, i.e., 2009 was compared to the last one, i.e., 2015(4.3% vs 25.6%; P < 0.0001). Accordingly, a higher prevalence of diabetes mellitus was present in NAFLD-HCC group 61.7% when compared to other than NAFLD-HCC 23.3%(P < 0.0001). Lower median AFP values at HCC diagnosis were observed between NAFLD-HCC and non-NAFLD groups(6.6 ng/m L vs 26 ng/m L; P = 0.02). Neither NAFLD nor other HCC etiologies were associated with higher mortality.CONCLUSION The growing incidence of NAFLD-HCC documented in the United States and Europe is also observed in Argentina, a confirmation with important Public Health implications.展开更多

Slum constitutes a habitat wherein various poverty related parameters are perpetually prevalent in the ambience. 1/6th of world population lives in slums yet there is no information regarding their health status in context to asthma and COPD. Aims: We investigated the prevalence of asthma and chronic-bronchitis symptoms and associated risk-factors in slum habitats of Pune city. Methodology: 7062 adult slum-dwellers living in 12 slums of Pune city were cross-sectionally interviewed by local healthcare workers with respiratory health questionnaire which was designed using respiratory symptoms of validated European Community Respiratory Health Survey (ECRHS II) questionnaire and International Union against Tuberculosis and Lung Disease (IUATLD) bronchial symptoms questionnaire. Results: The overall prevalence of selfreported asthma symptoms was 10% (18 - 40 years: 6.5%;>40 years: 13.5%). The overall prevalence of chronic bronchitis was 8.5% [18 - 40 years: 7% (males: 7%, females: 7%);>40 years: 10% (males: 10%, females: 10%)]. Increasing age (p = 0.00), female gender (p = 0.001), unemployment (0.00) current smoking (p = 0.00) and ex-smoking (p = 0.004) emerged as significant risk factor for asthma. While, ex-smoking (p = 0.004) and low-education status (p = 0.00) emerged as significant risk factors for chronic bronchitis. Conclusion: In slums reporting of asthma and chronic-bronchitis symptoms was much higher than what has been reported earlier from India. Asthma was commonly seen in females, old age, unemployed and ever-smokers. While chronic bronchitis was commonly seen in ex-smokers and illiterate subjects. Chronic bronchitis was equally distributed amongst male and females, despite 0% prevalence of smoking in females.展开更多
