Objectives To examine the association between long‐term bisphosphonate use and fracture in older women at high risk of fracture. Design Retrospective cohort. Setting Women's Health Initiative. Participants Older women who reported at least 2 years of bisphosphonate use in 2008–09 (N = 5,120). Measurements Exposure data were from a current medications inventory. Outcomes (hip, clinical vertebral, wrist or forearm, any clinical fracture) were ascertained annually. Using multivariate Cox proportional hazards models, the association between duration of bisphosphonate use (3–5, 6–9, 10–13 years) and fracture was estimated, using 2 years as the referent group. Results On average participants were 80 years old and were followed for 3.7 ± 1.2 years. There were 127 hip, 159 wrist or forearm, 235 clinical vertebral, and 1,313 clinical fractures. In multivariate‐adjusted analysis, 10 to 13 years of bisphosphonate use was associated with higher risk of any clinical fracture than 2 years of use (hazard ratio (HR) = 1.29, 95% confidence interval (CI) = 1.07–1.57). This association persisted in analyses limited to women with a prior fracture (HR = 1.30, 95% CI = 1.01–1.67) and women with no history of cancer (HR = 1.36, 95% CI = 1.10–1.68). The association of 10 to 13 years of use, compared with 2 years of use, was not statistically significant for hip (HR = 1.66, 95% CI = 0.81–3.40), clinical vertebral (HR = 1.65, 95% CI = 0.99–2.76), or wrist fracture (HR = 1.16, 95% CI = 0.67–2.00). Conclusion In older women at high risk of fracture, 10 to 13 years of bisphosphonate use was associated with higher risk of any clinical fracture than 2 years of use. These results add to concerns about the benefit of very long‐term bisphosphonate use.

Background The study aims to compare methods of determining headache directionality (imploding, exploding, and/or ocular headaches) in women with migraine, investigate the concordance between physician assignment and patient self‐assignment of pain directionality, and evaluate whether patients assigned their headaches to the same direction when queried using different methods. Directionality of migraine headache pain (imploding, exploding, or ocular) may reflect differences in the underlying pathogenesis of individual migraine attacks among and within individuals. Emerging evidence suggests that directionality of pain in migraine sufferers may predict response to onabotulinumtoxin A . The best method of determining headache directionality in migraine sufferers has not been systematically explored. Methods We conducted a prospective cross‐sectional survey study of 198 female patients with migraine presenting to a W omen's H ealth C linic. Patients determined the directionality (imploding, exploding, and/or ocular) of their own migraine pain by choosing among 3 pictures graphically representing directionality and also by responding to a written question regarding directionality. Clinicians then classified directionality of migraine pain using structured interviews. Concordance between clinician assignment of directionality and patient self‐assignment was determined with K appa coefficients. Results Subjects were females between the ages of 18 and 77 years (mean 48 years). According to patient selection of representative pictures, 62 (31.6%) had imploding headaches with or without ocular pain, 36 (18.4%) had exploding headaches with or without ocular pain, 78 (39.8%) had ocular pain only, and 20 (10.2%) had imploding and exploding headaches with or without ocular pain. Two subjects did not respond. According to patient responses to a written question, 80 (41.0%) had imploding headaches with or without ocular pain, 53 (27.2%) had exploding headaches with or without ocular pain, 46 (23.6%) had ocular pain only, and 16 (8.2%) had imploding and exploding headaches with or without ocular pain. Three subjects did not respond. For physician assignment, 69 (34.9%) subjects had imploding headaches with or without ocular pain, 89 (45%) had exploding headaches with or without ocular pain, 14 (7.1%) had ocular pain only, and 26 (13.1%) had imploding and exploding headaches with or without ocular pain. The concordance ( K appa coefficient) between physician assignment of headache directionality with patient response to the written question was 0.33 (weak agreement), between physician assignment and patient assignment via selection of representative pictures was 0.35 (weak agreement), and between patient assignment via written question and via selection of representative pictures was 0.35 (weak agreement). Conclusions The assignment of headache directionality varied substantially depending upon the method of determination. The concordance between clinician assignment, patient‐self assignment via answering a written question, and patient self‐assignment via choosing a representative picture was weak. Improved methods of determining pain directionality are needed.

Abstract Further analyses from the Women's Health Initiative estrogen trial shows that CEE reduced fracture risk. The fracture reduction at the hip did not differ appreciably among risk strata. These data do not support overall benefit over risk, even in women at highest risk for fracture. Introduction: The Women's Health Initiative provided evidence that conjugated equine estrogen (CEE) can significantly reduce fracture risk in postmenopausal women. Additional analysis of the effects of CEE on BMD and fracture are presented. Materials and Methods: Postmenopausal women 50–79 years of age with hysterectomy were randomized to CEE 0.625 mg daily (n = 5310) or placebo (n = 5429) and followed for an average 7.1 years. Fracture incidence was assessed by semiannual questionnaire and verified by adjudication of radiology reports. BMD was measured in a subset of women (N = 938) at baseline and years 1, 3, and 6. A global index was used to examine whether the balance of risks and benefits differed by baseline fracture risk. Results: CEE reduced the risk of hip (hazard ratio [HR], 0.65; 95% CI, 0.45–0.94), clinical vertebral (HR, 0.64; 95% CI, 0.44–0.93), wrist/lower arm (HR, 0.58; 95% CI, 0.47–0.72), and total fracture (HR, 0.71; 95% CI, 0.64–0.80). This effect did not differ among strata according to age, oophorectomy status, past hormone use, race/ethnicity, fall frequency, physical activity, or fracture history. Total fracture reduction was less in women at the lowest predicted fracture risk in both absolute and relative terms (HR, 0.86; 95% CI, 0.68–1.08). CEE also provided modest but consistent positive effects on BMD. The HRs of the global index for CEE were relatively balanced across tertiles of summary fracture risk (lowest risk: HR, 0.81; 95% CI, 0.62–1.05; mid risk: HR, 1.09; 95% CI, 0.92–1.30; highest risk: HR, 1.04; 95% CI, 0.88–1.23; interaction, p = 0.42). Conclusions: CEE reduces the risk of fracture and increases BMD in hysterectomized postmenopausal women. Even among the women with the highest risk for fractures, when considering the effects of estrogen on other important health outcomes, a summary of the burden of monitored effects does not indicate a significant net benefit.
