Prevalence of cytomegalovirus infection among patients undergoing hemodialysis.

CMV diseases predominantly occur as an opportunistic infection in patients with severe immunosuppression, such as cancer and renal failure patients, and rarely occur in immunocompetent patients. This study aimed to investigate the prevalence of CMV infection in patients undergoing hemodialysis and to compare the results of different serological tests for CMV infection.

Chlorination disinfection by-products in drinking water and the risk of adult leukemia in Canada.

The authors conducted a population-based case-control study of 1,068 incident leukemia cases and 5,039 controls aged 20-74 years during 1994-1997 to examine the association between exposure to drinking water chlorination disinfection by-products and adult leukemia risk in Canada. Residence and drinking water source histories and data from municipal water supplies were used to estimate individual chlorination disinfection by-product exposure according to water source, chlorination status, and chlorination disinfection by-product levels during the 40-year period before the interview. The analysis included 686 cases and 3,420 controls for whom water quality information was available for at least 30 of these years.
