      CONTEXT: Laboratory and epidemiological data suggest that folic acid may have an antineoplastic effect in the large intestine.

      OBJECTIVE: To assess the safety and efficacy of folic acid supplementation for preventing colorectal adenomas.

      DESIGN, SETTING, AND PARTICIPANTS: A double-blind, placebo-controlled, 2-factor, phase 3, randomized clinical trial conducted at 9 clinical centers between July 6, 1994, and October 1, 2004. Participants included 1021 men and women with a recent history ...

      BackgroundChanges to national guidelines for breast and cervical cancer screening have created confusion and controversy for women and their primary care providers.ObjectiveTo characterize women’s primary health care provider attitudes towards screening and changes in practice in response to recent revisions in guidelines for breast and cervical cancer screening.Design, Setting, ParticipantsIn 2014, we distributed a confidential web and mail survey to 668 women’s health care providers ...

      BACKGROUND AND METHODS: Laboratory, clinical, and epidemiologic evidence suggests that calcium may help prevent colorectal adenomas. We conducted a randomized, double-blind trial of the effect of supplementation with calcium carbonate on the recurrence of colorectal adenomas. We randomly assigned 930 subjects (mean age, 61 years; 72 percent men) with a recent history of colorectal adenomas to receive either calcium carbonate (3 g [1200 mg of elemental calcium] daily) or placebo, with ...

      STUDY DESIGN: A reliability assessment of standardized magnetic resonance imaging (MRI) interpretations and measurements.

      OBJECTIVE: To determine the intra- and inter-reader reliability of MRI features of lumbar spinal stenosis (SPS), including severity of central, subarticular, and foraminal stenoses, grading of nerve root impingement, and measurements of cross-sectional area of the spinal canal and thecal sac.

      SUMMARY OF BACKGROUND DATA: MRI is commonly used to assess patients with ...

      BACKGROUND: Laboratory and epidemiologic data suggest that aspirin has an antineoplastic effect in the large bowel.

      METHODS: We performed a randomized, double-blind trial of aspirin as a chemopreventive agent against colorectal adenomas. We randomly assigned 1121 patients with a recent history of histologically documented adenomas to receive placebo (372 patients), 81 mg of aspirin (377 patients), or 325 mg of aspirin (372 patients) daily. According to the protocol, follow-up colonoscopy ...

      STUDY DESIGN: Assessment of the reliability of standardized magnetic resonance imaging (MRI) interpretations and measurements.

      OBJECTIVE: To determine the intra- and inter-reader reliability of MRI parameters relevant to patients with intervertebral disc herniation (IDH), including disc morphology classification, degree of thecal sac compromise, grading of nerve root impingement, and measurements of cross-sectional area of the spinal canal, thecal sac, and disc fragment.

      PURPOSE: To characterize the inter- and intraobserver variability of qualitative, non-disk contour degenerative findings of the lumbar spine at magnetic resonance (MR) imaging.

      MATERIALS AND METHODS: The case accrual method used to perform this institutional review board-approved, HIPAA-compliant retrospective study was the random selection of 111 interpretable MR examination cases of subjects from the Spine Patient Outcomes Research Trial. The subjects were aged 18-87 years (mean, 53 ...

      BACKGROUND: Clinical trials have shown that calcium supplementation modestly decreases the risk of colorectal adenomas. However, few studies have examined the effect of calcium on the risk of different types of colorectal lesions or dietary determinants of this effect.

      METHODS: Our analysis used patients from the Calcium Polyp Prevention Study, a randomized, double-blind, placebo-controlled chemoprevention trial among patients with a recent colorectal adenoma. Nine hundred thirty ...

      BackgroundDespite substantial resources devoted to cancer screening nationally, the availability of clinical practice-based systems to support screening guidelines is not known.ObjectiveTo characterize the prevalence and correlates of practice-based systems to support breast and cervical cancer screening, with a focus on the patient-centered medical home (PCMH).DesignWeb and mail survey of primary care providers conducted in 2014.

      Experimental and observational findings suggest that calcium intake may protect against colorectal neoplasia. To investigate this hypothesis, we conducted a randomized, double-blind trial of colorectal adenoma recurrence. Nine hundred thirty patients with a recent history of colorectal adenomas were randomly given calcium carbonate (3 gm daily; 1200 mg elemental calcium) or placebo, with follow-up colonoscopies one and four years after the qualifying examination. The main analysis ...

      PURPOSE AND METHOD: Several studies have suggested that physical inactivity and obesity increase the risk for colorectal neoplasia. In this study, we investigated the association of physical activity and body mass index (BMI) with the risk of different types of large bowel polyps. We did an observational analysis nested within a randomized double-blind placebo-controlled chemoprevention trial among patients with one or more recently resected histologically confirmed colorectal adenoma. ...

      BACKGROUND: Melanoma incidence has increased in recent decades in the U.S.A. Uncertainty remains regarding how much of this increase is attributable to greater melanoma screening activities, potential detection bias and overdiagnosis.

      OBJECTIVES: To use a cross-sectional ecological analysis to evaluate the relationship between skin biopsy and melanoma incidence rates over a more recent time period than prior reports.

      METHODS: Examination of the association of biopsy rates and melanoma ...
