BACKGROUND Experimental animal studies suggest that olive oil consumption, as contrasted to consumption of other fat types, does not enhance the occurrence of chemically induced mammary tumors, but human data are sparse. Furthermore, evidence is inconclusive concerning the role of food groups, as distinct from that of major nutrients, in the etiology of(More)
The purpose of the Miyazaki Cohort Study is to describe and analyze the natural history of human T-cell lymphotropic virus type I (HTLV-I) in a highly endemic population in southwestern Japan. As of August 1995, 1,960 individuals have been enrolled, of whom 27% were HTLV-I antibody positive at baseline. Our achievements over the past decade of following(More)
A follow-up study was performed to analyze the effects of hepatitis C virus (HCV) infection on morbidity and mortality in the adult population from a village in Japan found to have endemic levels of both HCV and human T lymphotropic virus type I (HTLV-I). By use of the Cox proportional hazards model, rate ratios (RRs) and 95% confidence intervals (CIs) were(More)
Hepatitis C virus (HCV) is an important cause of liver disease throughout the world. However, the natural history and pathogenesis of this infection is still not completely understood. The aim of this study was to characterize the evolution of incident, asymptomatic HCV infection in a community-based population in Japan. The Miyazaki Cohort Study is a(More)
The presence of circulating "flower cells" and a low prevalence of antibody to Tax regulatory protein of human T-lymphotropic virus type I (HTLV-I) are characteristics of adult T-cell leukemia (ATL). To examine the predictability of levels of HTLV-I antibodies and of flower cell-like abnormal lymphocytes (Ably) for the risk of ATL among asymptomatic HTLV-I(More)
During a 16-month period in 1991-1992, blood samples and questionnaire data were obtained from 65 incident cases of hepatocellular carcinoma (HCC) as well as from 2 control groups of hospitalized patients matched on gender and age, which included 65 metastatic liver cancer (MLC) patients and 65 patients hospitalized for eye, ear, nose or throat conditions.(More)
OBJECTIVES Noninvasive markers of liver fibrosis correlate with the stage of liver fibrosis, but have not been widely applied to predict liver-related mortality. METHODS We assessed the ability of two indices of liver fibrosis, aspartate aminotransferase (AST)-to-platelet ratio index (APRI) and Fib-4, and two markers of extracellular matrix metabolism,(More)
OBJECTIVE To investigate whether female offspring of preeclamptic pregnancies have higher blood pressure, lower height, higher body mass index (BMI), and later age at menarche compared with offspring of normotensive pregnancies. METHODS Questionnaire information on age at menarche and measurements of blood pressure, height, and weight were collected among(More)
Human T lymphotropic virus type I (HTLV-I) is endemic in southern Japan and the Caribbean, but the incidence of HTLV-I-associated diseases varies across geographic areas. We compared markers of disease pathogenesis among 51 age- and sex-matched HTLV-I carrier pairs from Japan and Jamaica. The mean antibody titer (P=.03) and detection of anti-Tax antibody(More)
In this report, we quantified HTLV-I provirus load using the AmpliSensor system, which utilizes fluorescence to measure PCR products. With this method, provirus loads could be measured within 6 hr, and the results obtained correlated well with those obtained by other methods. Samples from 256 blood donors, who were positive for antibodies against HTLV-I,(More)
