The authors examined 1,615 workers exposed to dioxins in trichlorophenol production in Midland, Michigan, to determine if there were increased mortality rates from exposure. Historical dioxin levels were estimated by a serum survey of workers. Vital status was followed from 1942 to 2003, and cause-specific death rates and trends with exposure were evaluated. All cancers combined (standardized m...
BACKGROUND Although patients with end-stage renal disease (ESRD) experience excess mortality compared with the general population, the standardized mortality ratio (SMR) for Korean patients on dialysis has not yet been investigated. In this study, we evaluated the SMR among all Korean ESRD patients on maintenance dialysis in 2009 and 2010, and compared it according to age categories, sex, and d...
Small modular nuclear reactors (SMRs) represent a robust opportunity to develop low-carbon and reliable power with the potential meet cost parity conventional systems. This study presents detailed, bottom-up economic evaluation of 12 × 77 MWe (924 total) light-water SMR (LW-SMR) plant, 4 262 (1,048 MWe) gas-cooled (GC-SMR) 5 200 (1,000 molten salt (MS-SMR) plant. Cost estimates are derived from...
Several studies have linked inhalation of airborne arsenic with increased risk of respiratory cancer, but few have analyzed the shape of the exposure-response curve. In addition, since inhaled airborne arsenic affects systemic levels of inhaled arsenic, there is concern that inhaled arsenic may be associated with cancers of the skin, bladder, kidney, and liver, which have been linked to ingeste...
Background. Despite the high technical expertise in percutaneous mitral commissurotomy (PMC), mitral regurgitation (MR) remains a major procedure-related complication. The aim of this work is to find out the most sensitive and applicable predictors of development of significant mitral regurgitation (SMR) following percutaneous mitral commissurotomy using Inoue balloon technique. Methods. We stu...
OBJECTIVES To investigate the mortality of workers who had been exposed to asbestos, machining fluids and foundry work in a foundry and heavy engineering plant in the railway rolling stock manufacturing industry in New Zealand. METHODS Historical cohort study design. RESULTS For the total workforce of 3522 men employed between 1945 and 1991, follow up was 90% of person-years to 31 December ...
This chapter presents the fundamentals and applications of the State Machine Replication (SMR) technique for implementing consistent fault-tolerant services. Our focus here is threefold. First we present some fundamentals about distributed computing and three “practical” SMR protocols for different fault models. Second, we discuss some recent work aiming to improve the performance, modularity a...
The mortality experience of 1190 miners and 289 surface industry workers receiving workers' compensation awards for silicosis in Ontario since 1940 has been studied up to mid-1985. Both groups were found to have a significantly increased mortality from lung cancer (miners' SMR: 230; surface workers' SMR: 302) and stomach cancer (miners' SMR: 188; surface workers' SMR: 366). Adjustment for smoki...
BACKGROUND Despite several investigations, second malignancy risks (SMR) following radiotherapy alone (RT), chemotherapy alone (CT) and combined chemoradiotherapy (CRT) for Hodgkin's lymphoma (HL) remain controversial. PATIENTS AND METHODS We sought individual patient data from randomised trials comparing RT versus CRT, CT versus CRT, RT versus CT or involved-field (IF) versus extended-field ...
