Family history of cancer as a risk factor for second malignancies after Hodgkin's lymphoma

This study estimated the risk of second primary malignancies after Hodgkin's lymphoma (HL) in relation to family history of cancer, age at diagnosis and latency, among 6946 patients treated for HL in Sweden in 1965–1995 identified through the Swedish Cancer Register (SCR). First-degree relatives (FDRs) to the HL patients and their malignancies were then ascertained together with their malignancies through the Multi-Generation Registry and SCR. The HL patient cohort was stratified on the number of FDRs with cancer, and standardised incidence ratios (SIRs) of developing SM were analysed. In the HL cohort, 781 SM were observed 1 year or longer after HL diagnosis. The risk for developing SM increased with the number of FDRs with cancer, SIRs being 2.26, 3.01, and 3.45 with 0, 1, or ⩾2 FDRs with cancer, respectively. Hodgkin's lymphoma long-term survivors treated at a young age with a family history of cancer carry an increased risk for developing SM and may represent a subgroup where standardised screening for the most common cancer sites could be offered in a stringent surveillance programme

Preselection and expert advice

"The final authenticated version is available online at https://doi.org/10.1007/s00182-016-0551-9We study the effects of preselection on an expert’s advice about the execution of a project if its execution yields more precise estimates about the expert’s expertise. The in troduction of a preselection stage, in which the decision maker evaluates the project before asking for advice, alters the expert’s perception of the problem. We identify conditions under which preselection occurs in equilibrium. We show that if the expert adjusts his behavior, the option to preselect may reduce the expected utility of the decision maker.Collaborative Research Center 88

Comparison of phenol red and polyethyleneglycol as nonabsorbable markers for the study of intestinal absorption in humans

When phenol red and polyethyleneglycol were used simultaneously as nonabsorbable markers in perfusion studies of the absorptive capacity of high jejunum in humans, apparent absorption was the same when calculated from either marker. This similar indication of dilution and of absorption by the two markers was found in normal subjects and in patients with nontropical sprue, whether aqueous or saline solutions of dextrose were infused. The similarity strengthens the evidence that either phenol red or polyethyleneglycol is a satisfactory “nonabsorbable” marker compound to indicate dilution in perfusion studies of dextrose and electrolyte absorption in limited segments of human intestine.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44368/1/10620_2005_Article_BF02233070.pd
