    ABSTRACT: Nonalcoholic fatty liver disease (NAFLD) is a common condition comprising a wide spectrum of liver damage strongly associated with type 2 diabetes, obesity, and hyperlipidemia. The pathogenesis of fatty liver is multifactorial, and it has been suggested that the presence of insulin resistance (IR) is an essential requirement for the accumulation of hepatocellular fat. Although NAFLD may affect people of any age, in general, increasing age is associated with increasing prevalence. The aim of this study was to determine the prevalence of fatty liver and its influence on age and sex; and to assess the association of different degrees of fatty liver to IR and metabolic syndrome.

    ABSTRACT: Background Nonalcoholic fatty liver disease (NAFLD), which represents metabolic abnormality and reflects extra visceral fat deposition, has been shown to be a threat to public health and associated with cardiovascular risks. However, data regarding the differences in clinical presentation and related metabolic abnormalities in the aging group population remained scarce in the Taiwanese population. Methods We subsequently examined 8,658 subjects participating general health evaluation in Mackay Memorial hospital from 2003 to 2007. Baseline characteristics, anthropometrics, medical history, and biochemical markers were all collected. Abdominal ultrasonography was performed in all subjects. Two estimated cardiovascular risk scores were calculated according to criteria of the U.S. National Cholesterol Education Program Adult Treatment Panel III as metabolic score and Framingham risk score. Univariate logistic regression model was used to examine whether the baseline characteristics, anthropometrics, histories, and biochemical markers were independently associated with NAFLD from various age groups (young vs. aging groups) classified by 60 years of age. Respective receiver operating characteristic curves (ROC) with area under the curve were generated to test the capability of both cardiovascular risk scores in NAFLD discrimination from different age groups. Results Totally 7,204 subjects (mean age: 44.5 ± 11 years, 36% female) were finally enrolled in our study. Subjects with NAFLD were observed to have high body weight, body mass index, and circumferential waist and significantly abnormal biochemical markers accompanying worsening lipid profiles when compared with those without NAFLD in both the young and aging group populations (all p < 0.001) although alkaline phosphatase, total cholesterol, and low-density lipoprotein did not show significant differences with and without NAFLD in the aging group population. Diabetes history remained a strong independent predictor of NAFLD in both young and aging groups (odds ratio: 3.3, p < 0.001 vs. 2.51, p = 0.014). The prediction model by using different cardiovascular risk scores yielded a meaningful ROC value of 0.82 (young group) and 0.71 (aging group) (both p < 0.001) for metabolic score with ROC value of 0.67 (young group) and 0.52 (aging group) for Framingham risk score (p < 0.001 vs. 0.408, respectively). Conclusion The prevalence of NAFLD demonstrated a bimodal distribution with age in different genders. Although baseline characters and biochemical markers were demonstrated to be potential screening tools in detecting such clinical abnormality, they actually exerted diverse capabilities in the prediction of NAFLD in the different age groups. Traditional cardiovascular risk scores were less effective in predicting NAFLD in the aging group population.

    ABSTRACT: To analyze the characteristics of multiple primary malignancies (MPMs) of digestive system; including incidence, types of tumor combinations, time intervals between development of multiple tumors, clinical course, and prognostic factors affecting survival and mortality. Data from a total of 129 patients treated from January 1991 to December 2000 for pathologically proved MPMs, including at least one originating from the digestive system, were reviewed retrospectively. Among 129 patients, 120 (93.02%) had two primary cancers and 9 (6.98%) had three primary cancers. The major sites of MPMs of the digestive system were large intestine, stomach, and liver. Associated non-digestive cancers included 40 cases of gynecological cancers, of which 31 were carcinoma of cervix and 10 cases of genitourinary cancers, of which 5 were bladder cancers. Other cancers originated from the lung, breast, nasopharynx, larynx, thyroid, brain, muscle, and skin. Reproductive tract cancers, especially cervical, ovarian, bladder, and prostate cancers were the most commonly associated non-GI cancers, followed by cancer of the lung and breasts. Forty-three cases were synchronous, while the rest (86 cases) were metachronous cancers. Staging of MPMs and treatment regimes correlated with the prognosis between survival and non-survival groups. As advances in cancer therapy bring about a progressively larger percentage of long-term survivors, the proportion of patients with subsequent primary lesions will increase. Early diagnosis of these lesions, based on an awareness of the possibility of second and third cancers, and multidisciplinary treatment strategies will substantially increase the survival of these patients.
