Reduced bone mineral density is associated with breast arterial calcification.

BACKGROUND: Arterial calcification, a marker of atherosclerosis, results from a complex process of biomineralization resembling bone formation. Breast arterial calcification (BAC) has been associated with angiographic and clinical cardiovascular disease. The purpose of this study was to determine the association between reduced bone mineral density (BMD) and BAC, which may share a common pathophysiology. METHODS: We conducted a retrospective study of 228 women (55% Hispanic, mean age 64 +/-10 yr) who had both mammography and BMD evaluation at Columbia University Medical Center from 2001-2003. Each mammogram was reviewed for the presence of BAC using standardized methods. BMD was measured using dual-energy x-ray absorptiometry and categorized as normal, low bone density (osteopenia), or osteoporosis as defined by the World Health Organization. Univariate and multivariate logistic regression analyses were performed to evaluate the association between reduced BMD and BAC. RESULTS: The prevalence of BAC, low bone density (osteopenia), and osteoporosis was 39, 42, and 29%, respectively. Women with BAC were significantly more likely to be older, Hispanic, and postmenopausal and have osteoporosis as compared with women without BAC. In age-adjusted analyses, women with BAC were more likely to have reduced BMD (odds ratio 3.0, P < 0.01) as compared with women without BAC. Furthermore, osteoporosis was strongly associated with the presence of BAC (odds ratio 3.5, P < 0.01). CONCLUSION: These data suggest that osteoporosis and arterial calcification are strongly and independently correlated. Reduced BMD may identify women at risk of vascular disease.

Delays in breast cancer diagnosis and treatment by racial/ethnic group.

BACKGROUND: Although white women have the highest incidence of breast cancer, African American, followed by Hispanic, American Indian/Alaskan Native, and Asian American or Pacific Islander, women have higher death rates from the disease. Timely initiation of treatment has been shown to improve survival, and may help to lessen the mortality differences among racial/ethnic groups. METHODS: The purpose of this study was to describe time delays in the initial diagnosis and treatment of primary breast carcinoma across diverse ethnic/racial groups. Data are from the Surveillance, Epidemiology, and End Results-Medicare database. Women in this study were diagnosed as having breast cancer between January 1, 1992, and December 31, 1999. Billing claims from outpatient and inpatient visits were used. A total of 49 865 female Medicare recipients 65 years and older were enrolled in the study. Racial/ethnic groups were compared in their diagnostic, treatment, and clinical delay (ie, women with a diagnostic and treatment delay). RESULTS: African American women experienced the greatest diagnostic, treatment, and clinical delay. After controlling for other predictors, compared with white women, African American women had a 1.39-fold odds (95% confidence interval, 1.18-1.63) of diagnostic delay beyond 2 months, a 1.64-fold odds (95% confidence interval, 1.40-1.91) of treatment delay beyond 1 month, and a 2.24-fold odds (95% confidence interval, 1.75-2.86) of having a combined clinical delay. CONCLUSIONS: In a population-based study, African American women experienced the most delays in initial diagnosis and initiation of breast cancer treatment, relative to women of other racial/ethnic subgroups. Despite the limitations of a claims database, the magnitude and direction of the findings are consistent across the research, suggesting the critical importance of reducing these delays.

Prevalence of breast arterial calcifications in an ethnically diverse population of women.

PURPOSE: Breast arterial calcifications (BAC) identified on routine mammography have been associated with coronary heart disease (CHD) risk factors including diabetes and hypertension, angiographically defined CHD, and increased cardiovascular mortality. Accumulating evidence suggests that the mammogram may be an important tool to identify women at risk for CHD, however, the epidemiology of BAC has been poorly defined and previous studies limited to white populations. METHODS: The mammograms of 1905 consecutive women (51.2% Hispanic, 25.8% white, 15.3% black, 5.4% other, 2.2% Asian, ages 35-92 years) were evaluated for the presence of BAC and the number of calcified arteries. RESULTS: The overall prevalence of BAC was 29.4% and was significantly higher for Hispanics compared with whites (34.5% vs. 24.0%, p=0.0002) and lower for Asians compared with whites (7.1% vs. 24.0%, p < 0.02). Among BAC-positive women aged 65 years or less, blacks had more calcified arteries than whites (p < 0.01). The presence of BAC increased with age (p for trend < 0.0001). In age-adjusted models, older Hispanics were more likely to be BAC-positive than whites of similar age (p < 0.02). CONCLUSION: These results indicate that BAC varies significantly by age and race/ethnicity. These findings should be taken into consideration when designing future studies of BAC and CHD.

Gender differences in patient-spouse interactions: a sequential analysis of behavioral interactions in patients having osteoarthritic knee pain.

Theory and research suggest that spousal responses to displays of pain behavior can vary markedly. To our knowledge, observational research on spousal responses to pain behavior has been carried out only in chronic low back pain patients, but not in other populations. In this study systematic observations were conducted of interactions occurring between 50 married osteoarthritis patients (25 male and 25 female) and their respective spouses. Observations were conducted as the patient and spouse performed three common household tasks: sweeping the floor, folding laundry, and carrying small, artificial logs from one side of the room to the other. Contrary to prior research on chronic low back pain this study found that in osteoarthritis patients spouse facilitative behavior preceded and followed patient pain behavior significantly more often than did spouse solicitous behavior. A gender difference in spousal responding to pain behavior also was observed in that wives were significantly more likely to show facilitative behavior preceding and following patient pain behavior than were husbands. The implications of these findings for future research and clinical interventions focused on patient-spouse interactions are discussed.

Recent advances and future directions in the biopsychosocial assessment and treatment of arthritis.

This article provides an overview of the emerging literature on biopsychosocial assessment and treatment for two of the most common forms of arthritis: osteoarthritis and rheumatoid arthritis. The article is divided into 3 parts. In the 1st part, the basic elements of the biopsychosocial approach to assessing and treating persons having arthritis is described. In the 2nd part, the authors evaluate studies of biopsychosocial approaches to the assessment of arthritis pain and disability. Six research areas are reviewed: learned helplessness, depression, stress, pain coping, self-efficacy, and the social context of arthritis. The 3rd part of the article reviews studies that testing the efficacy of biopsychosocial treatment approaches for persons having osteoarthritis and rheumatoid arthritis.

Calcifications associated with lactational changes of the breast: mammographic findings with histologic correlation.

OBJECTIVE: We sought to describe the mammographic appearance of calcifications associated with histologically confirmed lactational changes of the breast. CONCLUSION: Calcifications associated with lactational changes of the breast may have a suspicious appearance on mammography. These calcifications may be identified on a patient's original screening mammogram or may be a new finding on an annual screening examination. Correlating a clinical history of recent lactation or a postpartum state is important in establishing a concordance between the mammographic and histologic findings. However, despite the benign nature of these calcifications, biopsy is recommended because of their suspicious morphologic features.
