Characterizing the basic reproduction number, R(0), for many wildlife disease systems can seem a complex problem because several species are involved, because there are different epidemiological reactions to the infectious agent at different life-history stages, or because there are multiple transmission routes. Tick-borne diseases are an important example where all these complexities are broug...

An important epidemiological consequence of aggregated host-parasite associations occurs when parasites are vectors of pathogens. Those hosts that attract many vectors will tend to be the focus of transmission. But to what extent, and can we identify characteristics of these key hosts? We investigated these questions with respect to the host-tick relationship of the yellow-necked mouse, Apodemu...

More than half of all cancer patients receive radiotherapy as a part of their treatment. With the increasing number of long-term cancer survivors, there is a growing concern about the risk of radiation induced second malignant neoplasm [SMN]. This risk appears to be highest for survivors of childhood cancers. The exact mechanism and dose-response relationship for radiation induced malignancy is...

Cancer survivors face many challenges as a result of their cancer diagnosis and treatment, most importantly the maintenance of physical well-being. Nurses and other health professionals strive to address the needs of cancer survivors, including providing appropriate health-promotion information for a physically active lifestyle. Cancer survivors are at greater risk for recurrence and for develo...

The risk adaptive therapy approach within low risk patients may involve limiting post-transplant IMiD exposure in patients who have a higher potential for SPM development. It may well be that we are looking at the tip of the iceberg in the year 2012 and SPMs may emerge as an important long-term sequela with further follow-up.

BACKGROUND Heightened risks of second cancers have been reported in patients with nonmelanoma cancer of the skin (NMSC), but this association has not been studied in a large, ethnically diverse, multigeographic population. METHODS This cross-sectional study assessed the association of NMSC with another malignancy in the Women's Health Initiative Observational Study, a study that was conducted...

First, patients may always develop a second severe illness, even a second cancer. Second, things are not always as they are expected to be. So, careful diagnosis is mandatory. Third, morphology is very important, but sometimes misleading. Always be aware of morphological variants!

o bjectives: the aim of this study was to investigate the displacement and stress distri- bution during surgically assisted rapid maxillary expansion under different surgical conditions with tooth- and bone-borne devices. materials and methods: three-dimensional (3d) finite element model of a maxilla was constructed and an expansion force of 100 n was applied to the left and right molars and pr...

Considerable research is aimed at determining the mechanism by which tumor cures, or regrows or second cancer develops, to be predictable and controllable. The wide range of doses, from low to very high, estimated statistically is responsible for such risks. A mathematical model is presented that describes both: the growth due to lower or over irradiated doses or the post therapy relapse of hum...
