This study examined the use of complementary and alternative medicine (CAM) therapies by breast cancer patients and the communication of their CAM use to their physicians relative to lymphedema symptoms and other factors. Breast cancer patients ( N = 148) in the State of Vermont were interviewed 2-3 years after their primary surgery using computer-aided telephone interviewing methods. Questionnaire items included demographic information, treatment, CAM use, lymphedema symptoms, and other measures. A large proportion (72.3%) reported using at least one CAM treatment after surgery. The most frequently used treatments were vitamins and nonfood supplements (72.3%), with herbal treatments, meditation, and traditional massage each being reported by about one-fifth of the women. Age, education, adjuvant chemotherapy, and extremity swelling were associated with use of more CAM treatments in a regression model. A large proportion (73.8%) of CAM users reported their CAM use to their physicians. Correlations between patients' income, adjuvant radiation therapy, and adjuvant tamoxifen use with communication of CAM use to their physicians were sought in a logistic regression model. CAM use is high among breast cancer patients in Vermont, and the number of CAM therapies used is related to demographic factors, adjuvant treatment, and lymphedema symptoms. Communication of CAM use to physicians appears to be multifaceted.
The disablement process model proposed by Nagi in 1965 and subsequently expanded by Verbrugge and Jette was used heuristically to study the relationships among morbidities and arm/shoulder function limitations that breast cancer survivors experience in the period following treatment. A telephone survey was administered to 148 patients (67%) from among 222 breast cancer survivors who had undergone surgery in 1997 and 1998. Sixty-three percent of respondents reported experiencing some numbness, while 35% noticed swelling. Between 13% and 15% reported moderate to severe pain. Similar proportions said the occurrence of pain ranged from intermittent to constant. Between 1% and 4% reported problems with shoulder abduction and flexion and a decrease in arm strength and daily use of the arm. Swellings in the torso and arm tended to cluster into two different factors. Numbness followed a similar pattern. Apart from numbness in the arm, all the other factors had strong significant associations with one another. In multiple regression analyses, current pain intensity and swelling in the arm were independently related to current functional status of the arm/shoulder. The results suggest that it may be feasible to use patients' self-reports to develop a simple lymphedema-specific tool to monitor the functional status of women living with or at risk for lymphedema. Such a tool, if properly designed and implemented, would allow for the timely introduction of lymphedema or pain management strategies to improve arm function and ultimately the quality of life of breast cancer survivors.
Fecal viral concentrations of 40 patients infected with norovirus genogroup GII.4 correlated with diarrhea duration and frequency of vomiting. Higher viral concentration and older age were independently associated with prolonged diarrhea (>4 days). These findings provide information on the pathogenesis and transmission of norovirus infections.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
