    Cardiovascular disease (CVD) is of increasing concern among breast cancer survivors. However the burden of this comorbidity in this group relative to the general population, and its temporal pattern, remains unknown

    Exposure to fogger trucks and breast cancer incidence in the Long Island Breast Cancer Study Project: a case-control study

    Background: Few studies have supported an association between breast cancer and DDT, usually assessed with biomarkers that cannot discern timing of exposure, or differentiate between the accumulation of chronic low-dose versus acute high-dose exposures in the past. Previous studies suggest that an association may be evident only among women exposed to DDT during biologically susceptible windows, or among those diagnosed with estrogen receptor/progesterone receptor-positive (ER+PR+) breast cancer subtypes. Self-reported acute exposure to a fogger truck, which sprayed DDT prior to 1972, was hypothesized to increase the risk of breast cancer, particularly among women exposed at a young age or diagnosed with ER+PR+ breast cancer. Methods: We examined these possibilities in the Long Island Breast Cancer Study Project (LIBCSP) (1,508 cases, 1,556 controls), which included exposure assessment by structured questionnaire and serum samples collected between 1996–1998, using adjusted logistic and polytomous regression to estimate ORs and 95% CIs. Results: Women with ER+PR+ breast cancer had a 44% increased odds of ever seeing a pre-1972 fogger truck compared to other subtypes (OR = 1.44; 95% CI 1.08-1.93). However, there was little variation in the observed increase in breast cancer risk when considering all women who reported seeing a pre-1972 fogger truck at their residence (OR = 1.16; 95% CI 0.98, 1.37), or during hypothesized susceptible windows. Self-reported acute exposure was not correlated with serum concentrations, a biomarker of long-term exposure. Conclusions: These findings support the hypothesis that seeing a fogger truck, a proxy measure for acute DDT exposure, may be associated with ER+PR+ tumors, the most commonly diagnosed breast cancer subtype among American women

    Shortened surveillance intervals following suboptimal bowel preparation for colonoscopy: Results of a national survey

    Purpose: Suboptimal bowel preparation can result in decreased neoplasia detection, shortened surveillance intervals, and increased costs. We assessed bowel preparation recommendations and the relationship to self-reported proportion of suboptimal bowel preparations in practice; and evaluated the impact of suboptimal bowel preparation on colonoscopy surveillance practices. A random sample of a national organization of gastroenterologists in the U.S. was surveyed. Methods: Demographic and practice characteristics, bowel preparation regimens, and proportion of suboptimal bowel preparations in practice were ascertained. Recommended follow-up colonoscopy intervals were evaluated for optimal and suboptimal bowel preparation and select clinical scenarios. Results: We identified 6,777 physicians, of which 1,354 were randomly selected; 999 were eligible, and 288 completed the survey. Higher proportion of suboptimal bowel preparations/week (≥10 %) was associated with hospital/university practice, teaching hospital affiliation, greater than 25 % Medicaid insured patients, recommendation of PEG alone and sulfate-free. Those reporting greater than 25 % Medicare and privately insured patients, split dose recommendation, and use of MoviPrep® were associated with a less than 10 % suboptimal bowel preparations/week. Shorter surveillance intervals for three clinical scenarios were reported for suboptimal preparations and were shortest among participants in the Northeast who more often recommended early follow-up for normal findings and small adenomas. Those who recommended 4-l PEG alone more often advised less than 1 year surveillance interval for a large adenoma. Conclusions: Our study demonstrates significantly shortened surveillance interval recommendations for suboptimal bowel preparation and that these interval recommendations vary regionally in the United States. Findings suggest an interrelationship between dietary restriction, purgative type, and practice and patient characteristics that warrant additional research

    Gastroenterologists' Perceived Barriers to Optimal Pre-Colonoscopy Bowel Preparation: Results of a National Survey

    Poor quality bowel preparation has been reported in almost one third of all colonoscopies. To better understand factors associated with poor bowel preparation, we explored perceived patient barriers to optimal pre-colonoscopy bowel preparation from the perspective of the gastroenterologist. A random sample of physician members of the American College of Gastroenterology was surveyed via the internet and postal mailing. Demographic and practice characteristics and practice-related and perceived patient barriers to optimal bowel preparation were assessed among 288 respondents. Lack of time, no patient education reimbursement, and volume of information were not associated with physician level of suboptimal bowel preparation. Those reporting greater than or equal to 10 % suboptimal bowel preparations were more likely to believe patients lack understanding of the importance of following instructions, have problems with diet, and experience trouble tolerating the purgative. Bowel preparation instruction communication and unmet patient educational needs contribute to suboptimal bowel preparation. Educational interventions should address both practice and patient-related factors

    Split dose and MiraLAX-based purgatives to enhance bowel preparation quality becoming common recommendations in the US

    Objectives: Rates of suboptimal bowel preparation up to 30% have been reported. Liberalized precolonoscopy diet, split dose purgative, and the use of MiraLAX-based bowel preparation (MBBP) prior to colonoscopy are recently developed measures to improve bowel preparation quality but little is known about the utilization prevalence of these measures. We examined the patterns of utilization of these newer approaches to improve precolonoscopy bowel preparation quality among American gastroenterologists. Methods: Surveys were distributed to a random sample of members of the American College of Gastroenterologists. Participants were queried regarding demographics, practice characteristics, and bowel preparation recommendations including recommendations for liberal dietary restrictions, split dose purgative, and the use of MBBP. Approaches were evaluated individually and in combination. Results: Of the 999 eligible participants, 288 responded; 15.2% recommended a liberal diet, 60.0% split dose purgative, and 37.4% MBBP. Diet recommendations varied geographically with gastroenterologists in the West more likely to recommend a restrictive diet (odds ratio [OR] 2.98, 95% confidence interval [CI] 1.16–7.67) and physicians in the Northeast more likely to recommend a liberal diet more likely. Older physicians more often recommended split dosing (OR 1.04, 95% CI 1.04–2.97). Use of MBBP was more common in suburban settings (OR 2.14, 95% CI 1.23–3.73). Evidence suggests that physicians in private practice were more likely to prescribe split dosing (p = 0.03) and less often recommended MBBP (p = 0.02). Likelihood of prescribing MBBP increased as weekly volume of colonoscopy increased (p = 0.03). Conclusions: To enhance bowel preparation quality American gastroenterologists commonly use purgative split dosing. The use of MBBP is becoming more prevalent while a liberalized diet is infrequently recommended. Utilization of these newer approaches to improve bowel preparation quality varies by physician and practice characteristics. Further evaluation of the patterns of usage of these measures is indicated
