Colorectal cancer (CRC) is the third most common cancer and third leading cause of cancer death in both men and women and second leading cause of cancer death when men and women are combined in the United States (US). Almost two-thirds of CRC survivors are living 5 years after diagnosis. Considering the recent decline in both incidence and mortality, the prevalence of CRC survivors is likely to increase dramatically over the coming decades with the increase in rates of CRC screening, further advances in early detection and treatment and the aging and growth of the US population. Survivors are at risk for a CRC recurrence, a new primary CRC, other cancers, as well as both short-term and long-term adverse effects of the CRC and the modalities used to treat it. CRC survivors may also have psychological, reproductive, genetic, social, and employment concerns after treatment. Communication and coordination of care between the treating oncologist and the primary care clinician is critical to effectively and efficiently manage the long-term care of CRC survivors. The guidelines in this article are intended to assist primary care clinicians in delivering risk-based health care for CRC survivors who have completed active therapy.

A geo-referenced data set of 12 228 first-time blood lead screening values for Syracuse, NY, children was established for the 4-year period 1992-1996. Soil lead values were measured in a 600 m by 600 m tessellation grid covering the city. The two data sets were merged for evaluation of relationships between them. Strong seasonal variation in blood lead levels suggests the importance of contaminated soils as an exposure source. When the data were aggregated at a large geographic scale (3 km^sup 2^), a logarithmic model showed an R^sup 2^ of > 0.65 for the regression of geometric mean blood lead on median soil lead values. Results showed a striking similarity to those obtained by Mielke et al. (1999) for a study in New Orleans, LA, USA.[PUBLICATION ABSTRACT]

Models of the Snowy Egret (Egretta thula), that use the tendency of wild birds to join foraging aggregations, were used in manipulative experiments to test the ability of wild individuals to use environmental and social information indicative of patch quality, including pool depth, prey accessibility, prey density, and prey exploitation, when choosing foraging patches. Snowy Egrets, but not some other aggregation species, preferred shallow (<20 cm) compared to deep (>40 cm) pools, perhaps because they could wade throughout the shallow pools, disturbing fish prey and making them more accessible for capture. Snowy Egrets responded to an artificial increase in fish density by visiting prey-enhanced pools more than pools with most fish removed or unmanipulated pools. Snowy Egrets also responded to a decrease in prey density resulting from recent exploitation by aggregations by visiting these pools less than unmanipulated pools. These results indicate that, in addition to the presence of other individuals, Snowy Egrets used discernible pool characteristics such as depth, as well as the availability and density of prey when choosing patches in which to forage.
