..To identify patterns and predictors of 1-year change in patient activation in chronically ill older adults...

..An alternative is using administrative health-care data to identify second breast cancer events; however, these algorithms must be validated against a gold standard...

..We review the uses of electronic health care data algorithms, measures of their accuracy, and reasons for prioritizing one measure of accuracy over another...

..We sought to estimate the direct cost, from the perspective of the health insurer or purchaser, of breast-care services in the year following a false positive screening mammogram compared with a true negative examination...

..Future studies with larger sample sizes should further examine individual drugs as well as dose, duration and recency of use...

..A few epidemiologic studies have investigated acid suppressant use and CRC risk; none has documented an overall association. We sought to investigate whether acid suppressants are associated with CRC risk...

..Several studies suggest antidepressant medications can increase prolactin levels. Some, but not all, studies suggest prolactin levels are positively associated with mammographic breast density, an established risk factor for breast cancer...

....

..Screening decreases colorectal cancer (CRC) incidence and mortality, yet almost half of age-eligible patients are not screened at recommended intervals...

..CONCLUSIONS: Overall, this study does not support the hypothesis that reproductive or menstrual factors, with the exception of oophorectomy status, are associated with postmenopausal androgen concentrations...

..These findings are of public health relevance and add a new facet to the growing literature on the health benefits of moderate exercise...

..Many trials have tested different strategies to increase colorectal cancer (CRC) screening. Few describe whether participants are representative of the population from which they are recruited...

..CONCLUSION: It appears that a year long moderate-intensity exercise program alone does not significantly alter serum lipoprotein levels among overweight/obese postmenopausal women...

..It is unknown whether postmenopausal unopposed estrogen users are better off, in terms of endometrial cancer risk, switching to a combined estrogen-progestin regimen or stopping hormone use altogether...

..This study investigated (1) the association between care coordination and continuity of primary care, and (2) differences in this association by level of specialty care use...

..The association between exercise and breast cancer risk may be partly explained by the effects of exercise on these hormones...

..This analysis was conducted to examine the effects of long-term aerobic exercise on serum sex hormones in middle-aged to older men...

..Some women with early-stage breast cancer are at higher risk of recurrence and can benefit from chemotherapy. We describe patterns of referral, receipt, and completion of chemotherapy among older women at high risk of recurrence...

..We conducted a larger self-report evaluation of endocrine therapy discontinuation associated with patient characteristics and therapy-related adverse effects...

....

..Screening decreases colorectal cancer (CRC) morbidity and mortality, yet remains underutilized. Screening breakdowns arise from lack of uptake and failure to follow-up after a positive screening test...

..This study provides further evidence that genetic variation may appreciably alter sex hormone concentrations in postmenopausal women not taking hormone therapy...
