This study was designed to obtain a general overview of gallstone disease in Italy. A total of 18 cohorts in 10 Italian regions were enrolled in this survey. Four cohorts were excluded from analysis because of a participation rate of less than 50 percent. Field activities started in December 1984 and terminated in April 1987. A precoded questionnaire was administered to each subject by a trained member of the medical staff. Participants underwent an ultrasonographic examination of the upper abdomen and blood sampling. Each research group was provided with an identical ultrasonographic machine. Standardized criteria were established for both the examination and diagnosis. The inter- and intraobserver variation in the ultrasonographic procedure was assessed using a reliability study. The overall kappa score for interobserver agreement was good (0.649), while intraobserver agreement was good or excellent (kappa scores > 0.60) in 75 percent of the observers. A total of 29,739 of the 46,139 (64.4 percent) enrolled subjects were examined. Among those with a clear-cut definition of the gallbladder status, 6.5 percent of the males and 10.5 percent of the females had gallstones. Additional 3.0 and 8.4 percents, respectively, had already undergone cholecystectomy. Prevalence of gallstone disease (gallstones plus cholecystectomy) increased linearly with age in both sexes. Among subjects with gallstones, 76.7 percent of men and 72 percent of women were not aware of having gallstones; 87.0 percent of men and 84.9 percent of women were asymptomatic. This study confirms that gallstone disease is a highly prevalent condition. Gallstones rarely cause symptoms, and subjects are mostly unaware of their presence.
Although most all laboratory and rotational thromboelastometry coagulation tests worsened over time when measured on-scene and in the ED, monitoring coagulation at the scene of trauma does not provide clinically important information in a majority of trauma patients. One hour after injury, significant activation and consumption of fibrinogen, FV, FXIII, protein C activity, and protein S were observed.
The relation of alcohol consumption to mortality is examined using the data of the Italian rural cohorts of the Seven Countries Study, a prospective investigation of factors related to cardiovascular disease (CVD). The present analysis includes 1536 men aged 45-64, whose dietary habits and food consumption, including alcoholic beverages, were measured in 1965. Of them, 463 men died in a follow-up period of 15 years. The analysis shows a J-shaped relationship between alcohol consumption, expressed as percentage of total daily energy intake, and both overall mortality and cardiovascular mortality; this J-shaped relationship is evident even after adjusting for age, cigarette smoking and occupation. The inverse relationship for consumption of small quantities of alcohol, which is represented by the left side of the J-curve, is no longer significant when all men with previous cardiovascular manifestations are excluded from the analysis, yet it is never completely eliminated.
Subjects with low TC levels (<189 mg/dL) are at higher risk of dying even when many related factors have been taken into account. Although more data are needed to clarify the association between TC and all-cause mortality in older individuals, physicians may want to regard very low levels of cholesterol as potential warning signs of occult disease or as signals of rapidly declining health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
