Hepatitis C virus genotype 3 was associated with the development of hepatocellular carcinoma in Korea.

J Viral Hepat 2019 Apr 8;26(4):459-465. Epub 2019 Jan 8.

Department of Internal Medicine, Gyeongsang National University School of Medicine and Gyeongsang National University Hospital, Jinju, Korea.

Although hepatitis C virus (HCV) genotype 3 infection is thought to be an important risk factor for hepatocellular carcinoma (HCC), current evidence is limited because only a few Western studies have evaluated the occurrence of HCC in patients with HCV genotype 3 infection. We evaluated the impact of genotype 3 and non-3 on HCC incidence and on disease progression in chronic HCV patients; this is the first study reporting such findings in an Asian population. We performed a retrospective cohort study using the data of 1448 consecutive chronic HCV patients evaluated at three centres in Korea between January 2005 and December 2016. Read More

Int J Cancer 2012 Mar 2;130(6):1387-94. Epub 2011 Aug 2.

HTA Service, Agency for Public Health, Lazio Region, Rome, Italy.

Concern was raised on using testing for high-risk (HR) human papillomavirus (HPV) in cervical cancer screening in populations where HPV prevalence is high. The impact of HR HPV prevalence on the efficiency of HPV test-based screening has never been directly evaluated. A meta-regression of the relationship between HR HPV prevalence and the specificity and positive predictive value (PPV) of HPV DNA testing for the presence of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) was performed.

High prevalence of febrile urinary tract infections after paediatric renal transplantation.

Nephrol Dial Transplant 2006 Nov 8;21(11):3269-74. Epub 2006 Sep 8.

Department of Pediatric Nephrology, Friedrich Schiller University Children's Hospital, Kochstrasse 2, D-07740 Jena, Germany.

J D Cooper S M Bird

J Cancer Epidemiol Prev 2002 ;7(2):59-70

MRC Biostatistics Unit, Cambridge, UK.

Background: Meat recovered mechanically from bovine vertebral columns for use in burgers, sausages and other meat products may have been contaminated with bovine spongiform encephalopathy (BSE) from recovered spinal cord and dorsal root ganglia (DRG). We quantified UK exposure to BSE in beef mechanically recovered meat (MRM) by birth cohort (born pre-1940, in 1940-1969, post-1969), gender and calendar period (1980-1989, 1990-1996) because information on any two of BSE exposure intensity, vCJD incubation period and the new cases of vCJD tells us about the third.

Methods: Synthesis of evidence on BSE epidemiology, MRM production, infectivity in spinal cord and DRG, and UK dietary consumption. Read More

Longitudinal study of prognostic factors in established periodontitis patients.

J Clin Periodontol 1997 Feb;24(2):102-9

Department of Oral Biology, School of Dental Medicine State University of New York at Buffalo, USA.

Numerous indicators for disease progression have been described in the last decade. The purpose of this study was to examine, longitudinally, a large battery of clinical, microbiological, and immunological indicators, to try to determine whether the presence of one or a combination of these parameters at baseline, would correlate positively with increased attachment and or bone loss (true prognostic factors). Following initial screening, 79 patients with established periodontitis were monitored longitudinally for one year. Read More
