The effect of classic breast cancer risk factors on hormone receptor-defined breast cancer is not fully clarified. We explored these associations in a Swedish population-based study. PRÀ tumors (OR, 1.3; 95% CI, 0.7-2.5). In conclusion, other risk factors were similarly related to breast cancer regardless of receptor status, but high age at first birth, substantial weight gain in adult age, and use of menopausal estrogen-progestin therapy were more strongly related to receptor-positive breast cancer than receptornegative breast cancer.

key words: instrumental activities of daily living, older adults, dementia ABSTRACT People with mild cognitive impairment or dementia in a mild phase who live at home are expected to manage the everyday technology that is common in this context. However, the knowledge of how technology use may interfere with the performance of daily activities is sparse. The purpose of this study was to evaluate whether a new instrument measuring relevance and competence in everyday technology use, the Everyday Technology Use Questionnaire, could generate linear measures of competence in a valid manner when used in a population of 157 older adults with and without cognitive impairment or dementia. The results from this study indicate that the Everyday Technology Use Questionnaire demonstrates acceptable levels of scale validity and person response validity, supporting researchers and clinicians with a tool that generates a valid measure of competence in use of everyday technology for people with mild cognitive impairment or dementia in a mild phase who live at home.

Introduction Breast cancers of different histology have different clinical and prognostic features. There are also indications of differences in aetiology. We therefore evaluated the risk of the three most common histological subtypes in relation to menopausal hormone therapy and other breast cancer risk factors.

The aim of this paper is to advance our understanding of participation and its relation to occupation, by analysing the daily occupational experiences of six men and women living with chronic pain. Open-ended interviews are used in conjunction with a constant comparative method of analysis. The findings are thematically presented as: "taking initiative and making choices", doing something physical", "doing something social", and "doing something for others". Furthermore, a short vignette is presented in which the authors attempt to juxtapose theoretical constructs with individual experiences in order to illustrate another level of contextual richness of the data. Methodological implications are discussed in relation to the findings, analytic presentation, and previous research.

Technology is believed to have a potential for supporting significant others of people with dementia but little is known of their experiences and views of technology. The aim of this study is to explore how significant others relate to technology and to their relatives with dementia as technology users. The focus is on both their own use of technology as significant others and the use of technology by their relatives with dementia. Individual interviews and focus group discussions were undertaken and analyzed using a grounded theory approach. The significant others showed an overall readiness toward using technology in their present roles. Technology use in daily activities was perceived to be an important means to keeping retained abilities exercised but could also be perceived as a possible threat to health if activities were oversimplified. The significant others asked for flexible technology not perceived as stigmatizing, to be integrated into existing habits.

Although certain risk factors for breast cancer incidence may also effect survival, findings have been inconsistent and the long-term role of childbirth is unknown. We studied the influence of number and timing of births on breast cancer prognosis prospectively. From 1958 to 1997, altogether 32,003 women, born 1932 or later, were notified to the Swedish Cancer Registry due to a primary invasive breast cancer. We obtained information on dates of all childbirths and achieved complete follow-up through 1997 by means of linkage to other nation-wide databases. Proportional hazards analyses were used to compute crude and multivariate hazard ratios (HR) with 95% confidence intervals (CI) of dying from breast cancer. We found a successively worse prognosis for women with a shorter delay between their last birth and breast cancer diagnosis (p for trend <0.0001). Compared to women with their last birth more than 10 years before diagnosis, the multivariate HR of breast cancer death was 1.39 (95% CI 1.17-1.67) for those with breast cancer diagnosis in the 3rd year after last birth and 1.72 (CI 95% 1.42-2.09) for those with diagnosis within 1 year after last birth. This adverse effect on prognosis of childbirth persisted beyond 10 years among women with a first birth before the age of 20 years. A pregnancy has marked adverse effects on the prognosis of a breast cancer diagnosed within 10 years after delivery. These findings suggest that pregnancy influences tumor biology.

Introduction Menopausal hormone therapy has been reported to increase the risk of certain subtypes of breast cancer and to be associated with a favorable survival. These associations could either be due to an increased mammographic surveillance or to a biological effect. We assessed these associations in a Swedish cohort of postmenopausal breast cancer patients holding information on mammographic examinations, menopausal hormone therapy use, other breast cancer risk factors, and cancer treatment.
