Adequacy of Communicating Results From Screening Mammograms to African American and White Women

Objective. We examined whether African American women were as likely as White women to receive the results of a recent mammogram and to self-report results that matched the mammography radiology report (i.e., were adequately communicated). We also sought to determine whether the adequacy of communication was the same for normal and abnormal results. Methods. From a prospective cohort study of mammography screening, we compared self-reported mammogram results, which were collected by telephone interview, to results listed in the radiology record of 411 African American and 734 White women who underwent screening in 5 hospital-based facilities in Connecticut between October 1996 and January 1998. Using multivariate logistic regression, we identified independent predictors of inadequate communication of mammography results. Results. It was significantly more common for African American women to experience inadequate communication of screening mammography results compared with White women, after adjustment for sociodemographic, access-to-care, biomedical, and psychosocial factors. Abnormal mammogram results resulted in inadequate communication for African American women but not White women (P\u3c.001). Conclusions. African American women may not be receiving the full benefit of screening mammograms because of inadequate communication of results, particularly when mammography results are abnormal

Quality and Publication of Emergency Medicine Trials Registered in ClinicalTrials.gov

Introduction: Promoting emergency medicine (EM) clinical trials research remains a priority. To characterize the status of clinical EM research, this study assessed trial quality, funding source, and publication of EM clinical trials and compared EM and non-EM trials on these key metrics. We also examined the volume of EM trials and their subspecialty areas.Methods: We abstracted data from ClinicalTrials.gov (February 2000 - September 2013) and used individual study National Clinical Trial numbers to identify published trials (January 2007 - September 2016). We used descriptive statistics and chi-square tests to examine study characteristics by EM and non-EM status, and Kaplan-Meier curves and log-rank tests to compare time to publication of completed EM and non-EM studies.Results: We found 638 interventional EM trials and 59,512 non-EM interventional trials conducted in the United States between February 2000 and September 2013, registered on ClinicalTrials.gov. EM studies were significantly less likely than non-EM studies to be National Institutes of Health-funded or to evaluate a drug or biologic. However, EM studies had significantly larger sample sizes, and were significantly more likely to use randomization and blinding. Overall, 34.3% of EM and 26.0% of non-EM studies were published in peer-reviewed journals. By subspecialty, more EM trials concerned medical/surgical and psychiatric/neurological conditions than trauma.Conclusion: Although EM studies were less likely to have received federal or industry funding, and the EM portfolio consisted of only 638 trials over the 14-year study period, the quality of EM trials surpassed that of non-EM trials, based on indices such as randomization and blinding. This novel finding bodes well for the future of clinical EM research, as does the higher proportion of published EM than non-EM trials. Our study also revealed that trauma studies were under-represented among EM studies. Periodic assessment of EM trials with the metrics used here could provide an informative and valuable longitudinal view of progress in clinical EM research

Cigarette smoking and risk of meningioma: the effect of gender.

BACKGROUND: A number of studies have reported on the association between smoking and meningioma risk, with inconsistent findings. We examined the effect of gender on the association between cigarette smoking and risk of intracranial meningioma in a large population-based, case-control study. METHODS: The data include 1,433 intracranial meningioma cases aged 29 to 79 years diagnosed among residents of the states of Connecticut, Massachusetts, North Carolina, the San Francisco Bay Area and eight Texas counties between May 1, 2006 and April 28, 2011 as well as 1,349 controls that were frequency matched on age, sex, and geography. The data are analyzed separately and in a meta-analysis with six previously reported studies. RESULTS: Female cases who reported having ever smoked were at significantly decreased risk of intracranial meningioma (OR, 0.8; 95% CI, 0.7-0.9) in contrast to male cases who were at increased risk (OR, 1.3; 95% CI, 1.0-1.7). Similar findings were noted for current and past smokers. Smoking-induced risk for females did not vary by menopausal status. For males, increased duration of use (P = 0.04) as well as increasing number of pack-years (P = 0.02) was associated with elevated risk. A meta-analysis including 2,614 cases and 1,179,686 controls resulted in an OR for ever smoking of 0.82 (95% CI, 0.68-0.98) for women and 1.39 (95% CI, 1.08-1.79) for men. CONCLUSION: The association of cigarette smoking and meningioma case status varies significantly by gender with women at reduced risk and men at greater risk. IMPACT: Whether the observed differences are associated with a hormonal etiology will require additional investigation

Exogenous hormone use, reproductive factors, and risk of intracranial meningioma in females.

ObjectThe 2-fold higher incidence of meningioma in women compared with men has long suggested a role for hormonally mediated risk factors, but specific mechanisms remain elusive.MethodsThe study included data obtained in 1127 women 29-79 years of age with intracranial meningioma diagnosed among residents of Connecticut, Massachusetts, North Carolina, the San Francisco Bay Area, and 8 Texas counties between May 1, 2006, and October 6, 2011, and data obtained in 1092 control individuals who were frequency matched for age group and geography with meningioma patients.ResultsNo association was observed for age at menarche, age at menopause, or parity and meningioma risk. Women who reported breastfeeding for at least 6 months were at reduced risk of meningioma (OR 0.78, 95% CI 0.63-0.96). A significant positive association existed between meningioma risk and increased body mass index (p < 0.01) while a significant negative association existed between meningioma risk and current smoking (p < 0.01). Among premenopausal women, current use of oral contraceptives was associated with an increased risk of meningiomas (OR 1.8, 95% CI 1.1-2.9), while current use of hormone replacement therapy among postmenopausal women was not associated with a significant elevation in risk (OR 1.1, 95% CI 0.74-1.67). There was no association between use of fertility medications and meningioma risk.ConclusionsThe authors' study confirms associations for body mass index, breastfeeding, and cigarette smoking but provides little evidence for associations of reproductive and menstrual factors with meningioma risk. The relationship between current use of exogenous hormones and meningioma remains unclear, limited by the small numbers of patients currently on oral hormone medications and a lack of hormone receptor data for meningioma tumors

Endogenous and exogenous hormone exposure and the risk of meningioma in men

OBJECT: Meningioma is a disease with considerable morbidity and is more commonly diagnosed in females than in males. Hormonally related risk factors have long been postulated to be associated with meningioma risk, but no examination of these factors has been undertaken in males. METHODS: Subjects were male patients with intracranial meningioma (n = 456), ranging in age from 20 to 79 years, who were diagnosed among residents of the states of Connecticut, Massachusetts, and North Carolina, the San Francisco Bay Area, and 8 counties in Texas and matched controls (n = 452). Multivariate logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CI) for the association between hormonal factors and meningioma risk in men. RESULTS: Use of soy and tofu products was inversely associated with meningioma risk (OR 0.50 [95% CI 0.37–0.68]). Increased body mass index (BMI) appears to be associated with an approximately 2-fold increased risk of developing meningioma in men. No other single hormone–related exposure was found to be associated with meningioma risk, although the prevalence of exposure to factors such as orchiectomy and vasectomy was very low. CONCLUSIONS: Estrogen-like exogenous exposures, such as soy and tofu, may be associated with reduced risk of meningioma in men. Endogenous estrogen–associated factors such as high BMI may increase risk. Examination of other exposures related to these factors may lead to better understanding of mechanisms and potentially to intervention
