For many years there has been controversy concerning the role of genetic influences in the pathogenesis of age-related macular disease. It is widely believed that the lesions causing visual loss occur in response to age-related changes in Bruch's membrane which are recognised clinically as drusen. In this study the density, size, and confluence of drusen as shown on colour photographs were comp...

We first use life-table methods to simulate the impact of the declining age gap on the risk of widowhood. We then use the Medicare Current Beneficiary Survey and the Census Public Use Microdata Samples to estimate the impact of widowhood, and other characteristics, on the prob...

A family history is an identified risk factor for colorectal cancer (CRC). However, it is not known to what extent the risk is due to environmental or heritable genetic factors. We wanted to examine this question for familial CRC adenocarcinoma based on the nationwide Swedish Family-Cancer Database on 10.3 million individuals whose invasive cancers were followed up to year 2000. Standardized in...
