Aspirin and Epithelial Ovarian Cancer 总被引:6,自引:0,他引:6
Arslan Akhmedkhanov M.D. Paolo Toniolo M.D. MSPH Anne Zeleniuch-Jacquotte M.D. M.S. Ikuko Kato M.D. Ph.D. Karen L. Koenig Ph.D. Roy E. Shore Ph.D. Dr.P.H. 《Preventive medicine》2001,33(6):682-687
BACKGROUND: Epidemiological evidence suggests that chronic inflammation may influence ovarian carcinogenesis. The study objective was to examine the association between the commonly used anti-inflammatory drug aspirin and epithelial ovarian cancer. METHODS: The authors conducted a case-control study based in the New York University Women's Health Study cohort enrolled between 1985 and 1991 in New York City. After a median follow-up period of 12 years, 68 incident cases of epithelial ovarian cancer were identified. Data about regular aspirin use were collected during the 1994-1996 follow-up questionnaire. Using a case-control study design, 10 controls per case were randomly selected among study participants who matched the case by age and menopausal status. Conditional logistic regression analysis was used to study the relationships between aspirin and epithelial ovarian cancer by generating odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Relative to no aspirin use, the OR for epithelial ovarian cancer among women who reported aspirin use three or more times per week for a period of at least 6 months was 0.60 (95% CI 0.26, 1.38), after adjustment for age at menarche, parity, oral contraceptive use, and first-degree family history of breast cancer before age 50. Among recent, within the previous 5 years, users of aspirin, the adjusted OR was 0.36 (95% CI 0.11, 1.18). CONCLUSION: Although confidence intervals included unity, the observed risk estimates seem to be compatible with previous studies suggesting that regular aspirin use could be inversely associated with risk of epithelial ovarian cancer. 相似文献

PURPOSE: The optimum approach to providing the Congressionally mandated gender-specific services for which women veterans are eligible is unknown. We evaluated onsite availability of gynecologic services, clinic type and staffing arrangements, and the impact of having a gynecology clinic (GYN) and/or an obstetrician gynecologist (OBGYN) routinely available. METHODS: We analyzed data from the 2001 national VHA Survey of Women Veterans Health Programs and Practices (n = 136 sites; response rate, 83%). We assessed availability of gynecologic services, and evaluated differences in availability by clinic type (designated women's health provider in primary care [PC], separate women's health clinic for primary care [WHC], and/or separate GYN) and staffing arrangements (OBGYN routinely involved versus not). MAIN FINDINGS: Out of 133 sites, 77 sites (58%) offered services through a GYN and 56 sites (42%) did not have GYN. Seventy-two (54%) sites had a WHC. More sites with an OBGYN provided endometrial biopsies (91% vs. 20%), IUD insertion (85% vs. 14%), infertility evaluation (56% vs. 23%), infertility treatment (25% vs. none), gynecologic surgery (65 vs. 28%), p < .01. In comparison to sites without WHC, those with WHC were more likely to offer services onsite: endometrial biopsy odds ratio (OR) 6.0 (95% confidence interval [CI], 2.0-18.1); IUD insertion 4.4 (1.6-12.2); infertility evaluation 2.8 (1.2-6.3); and gynecologic surgery 2.3 (1.0-5.4). CONCLUSION: As the VA develops strategic plans for accommodating the growing number of women veterans, leaders should consider focusing on establishing WHC for primary care and routine availability of OBGYN or other qualified clinicians, rather than establishing separate GYN. 相似文献

CONTEXT: There is a growing recognition of the need to measure and report hospital financial performance. However, there exists little comparative financial indicator data specifically for critical access hospitals (CAHs). CAHs differ from other hospitals on a number of dimensions that might affect appropriate indicators of performance, including differences in Medicare reimbursement, limits on bed size and average length of stay, and relaxed staffing rules. PURPOSE: To develop comparative financial indicators specifically designed for CAHs using Medicare cost report data. METHODS: A technical advisory group of individuals with extensive experience in rural hospital finance and operations provided advice to a research team from the University of North Carolina at Chapel Hill. Twenty indicators deemed appropriate for assessment of CAH financial condition were chosen and formulas determined. Issues 1 and 2 of the CAH Financial Indicators Report were mailed to the chief executive officers of 853 CAHs in the summer of 2004 and 1,092 CAHs in the summer of 2005, respectively. Each report included indicator values specifically for their CAH, indicator medians for peer groups, and an evaluation form. FINDINGS: Chief executive officers found the indicators to be useful and the underlying formulas to be appropriate. The multiple years of data provide snapshots of the industry as a whole, rather than trend data for a constant set of hospitals. CONCLUSIONS: The CAH Financial Indicators Report is a useful first step toward comparative financial indicators for CAHs. 相似文献

Objective: To estimate the incremental cost-utility ratio (ICUR) of rimonabant 20 mg/day in the treatment of obesity from a third-party payer's perspective.
Methods: Pooled data from three randomized clinical trials were used to develop a decision tree with five treatment alternatives: 1- and 2-year treatment with rimonabant, 2-year placebo, 1-year rimonabant followed by 1-year placebo, and no treatment. All alternatives, except no treatment, were accompanied by lifestyle interventions. Treatment benefits included gains in quality-adjusted life-years (QALYs) and reduced incidence of type-2 diabetes mellitus and coronary heart disease (CHD). Drug acquisition cost was based on the average wholesale price of a comparator drug minus 15%. One-way and probabilistic sensitivity analyses were conducted to assess the stability of the base-case results.
Results: One-year rimonabant and 1-year rimonabant followed by placebo were extendedly dominated. Rimonabant for 2 years showed an average weight reduction of 8.49 kg, a body mass index reduction of 2.98 kg/m2 and reduced waist circumference by 8.24 cm (placebo: 3.55 kg, 1.22 kg/m2 , 4.18 cm). Two-year rimonabant was associated with a relative reduction in the 5-year incidence of CHD by 7.15% and of diabetes by 9.28%. Incremental benefits (costs) were 0.0984 QALYs ($5209) compared to no treatment and 0.0581 QALYs ($4182) compared to placebo, producing ICURs of $52,936/QALY (95% confidence interval $39K–$69K) and $71,973/QALY ($51K–$98K), respectively.
Conclusions: Rimonabant combined with lifestyle interventions has the potential to decrease the rate of obesity-related comorbidities and improve health-related quality of life, albeit at considerable cost. 相似文献

Background: The relationship between hospital volume and outcomes needs to be further elucidated for low-risk procedures such as surgical
therapy of localized breast cancer. The objective of this investigation was to assess the relationship between hospital volume
and outcomes for breast cancer surgery.
Methods: A total of 233,247 patients who underwent breast-conserving therapy (BCT) and breast-ablative therapy (BAT) for localized
breast cancer were extracted from 13 years (1988–2000) of the Nationwide Inpatient Samples. Hospital volume was classified
as low (<30 cases/year), intermediate (≥ 30 to <70cases/year), and high (≥ 70 cases/year). Multiple linear and logistic regression
analyses were used to assess the risk-adjusted association between hospital volume and outcomes.
Results: In risk-adjusted analyses, patients operated on at low-volume hospitals were 3.04 (p = 0.03) times more likely to die after BCT compared with patients operated on at high-volume hospitals. Similarly, low-volume
hospitals had a significantly higher likelihood of postoperative complications (odds ratio [OR] = 1.73, p = 0.01 for BCT; OR = 1.44, p < 0.001 for BAT) compared with high-volume hospitals. Compared with low-volume hospitals, length of hospital stay was significantly
shorter and nonroutine patient discharge significantly lower for high-volume providers for both BCT and BAT (all p < 0.001). Patients were also significantly less likely to undergo BCT if operated on in a low- or intermediate-volume hospital
compared with a high-volume provider (p < 0.001).
Conclusions: High-volume hospitals had significantly lower nonroutine patient discharge, postoperative morbidity and mortality, shorter
length of hospital stay, and higher likelihood of performing BCT. Referral of patients with localized breast cancer to high-volume
hospitals may be justified. 相似文献

Molecular diagnostic tests are more sensitive and, in many cases, more specific than conventional laboratory methods for the
detection of sexually transmitted infections. Here, we review recently developed molecular methods for the diagnosis and subtyping
of the most common sexually transmitted infections: infections caused by Chlamydia trachomatis, Neisseria gonorrhoeae, human papillomavirus, Trichomonas vaginalis, and the agents of genital ulcer disease (Haemophilus ducreyi, herpes simplex virus, Treponema pallidum, and Calymmatobacterium granulomatis). We also provide an overview of the laboratory diagnostic tests and clinical specimens to use when infection with these
agents is suspected. 相似文献

OBJECTIVE: To better understand public beliefs and use of antibiotics for acute respiratory illnesses. DESIGN: Cross-sectional telephone survey. PARTICIPANTS: Three hundred eighty-six adult members (aged 18 years or older) of a group-model HMO in the Denver metropolitan area. MEASUREMENTS AND MAIN RESULTS: Two hundred seventy-three (70%) of the respondents reported that antibiotics were beneficial for bacterial respiratory illnesses, 211 (55%) reported that antibiotics were beneficial for viral respiratory illnesses, and 82 (21%) reported that antibiotics were beneficial for bacterial but not for viral illness. Multivariate regression analysis identified consulting an advice nurse (odds ratio [OR] 2.9; 95% confidence interval [CI] 1.7, 5.3), ever being told by a provider that antibiotics were not needed for a respiratory illness episode (OR 2.0; 95% CI 1.2, 3.6), having a chronic medical condition (OR 2.0; 95% CI 1.0, 3.9), and believing antibiotics to be helpful for viral (OR 2.5; 95% CI 1.3, 4.7) or bacterial (OR 2.6; 95% CI 1.2, 6.7) respiratory illnesses to be independently associated with antibiotic use for respiratory illnesses during the previous year. There was a trend toward lower previous antibiotic use among those believing antibiotics to be helpful for bacterial illness but not for viral illness. CONCLUSIONS: A lack of understanding about antibiotic effectiveness exists in the community. Increased previous antibiotic use among those believing antibiotics to be effective for viral illnesses suggests that improvements are needed in communications to patients and the public about antibiotic appropriateness. 相似文献
