“Background: New developments in the search for susceptibility alleles in complex disorders provide support for the possibility of a polygenic approach to the prevention and treatment of common diseases.

Methods: We examined the implications, both for individualized disease prevention and for public health policy, of findings concerning the risk of breast cancer that are based

on common genetic variation.

Results: Our analysis suggests that the risk profile find more generated by the known, common, moderate-risk alleles does not provide sufficient discrimination to warrant individualized prevention. However, useful risk stratification may be possible in the context of programs for disease prevention in the general population.

Conclusions: The clinical use of single, common, low-penetrance genes is limited, but a few susceptibility alleles may distinguish women who are at high risk for breast cancer from those who are at low risk, particularly

in the context of population screening.”
“Background Both end-stage renal disease and chronic kidney disease are increasing worldwide; however, the full effect of chronic kidney disease is unknown because mortality risks for all five stages are unavailable. We assessed prevalence and mortality risks for all stages of chronic kidney disease selleck and quantified its attributable mortality in Taiwan.

Methods The cohort consisted of 462 293 individuals aged older than 20 years who participated in a standard medical screening programme since 1994. As of Dec 31, 2006, we identified 14436 deaths. Chronic kidney disease was determined by glomerular filtration rate and urinary protein. We estimated national prevalence in Taiwan from the cohort by adjusting age and educational levels. Hazard ratios (HRs) were calculated with Cox proportionate hazards model. We calculated mortality attributable to chronic kidney disease for national population and for low socioeconomic status.

Findings The secondly national prevalence of chronic kidney disease was 11.93%

(95% Cl 11.66-12.28), but only 3.54% (3.37-3.68) of participants in the cohort were aware of their disorder. Prevalence was substantially higher in the group with low socioeconomic status than in the high status group (19.87% [19.84-19.91] vs 7.33% [7.31-7.35]). 56 977 (12%) of cohort participants had chronic kidney disease; those with disease had 83% higher mortality for all cause (HR 1 . 83 [1 . 73-1.93]) and 100% higher for cardiovascular diseases (2 . 00 [1.78-2. 25]), in a cohort that was observed for 13 years with median follow-up of 7.5 years (IQR 4. 0-10. 1). 10.3% (95% CI 9 .57-11.03) of deaths in the entire population were attributable to chronic kidney disease, but 17.5% (16.27-18.67) of deaths in the low socioeconomic status population. 2350 (39%) deaths occurred before 65 years of age in those with chronic kidney disease.
