RESUMO
Inadequate inpatient bowel preparation can lead to repeat procedures, prolonged hospital stays, and increased financial burden. In this quality improvement project, the authors developed an electronic medical record (EMR)-based order set with precise instructions and anticipatory guidance for inpatient bowel preparation before colonoscopy. The current study is a nonrandomized intervention study. The authors compared 2 groups: an intervention group using a newly developed, consensus-based, standardized EMR bowel preparation order set and a control group using previously existing EMR bowel preparation orders. Bowel preparation outcomes were followed over the course of 16 months. The aim was to improve inpatient colonoscopy bowel preparation, as evaluated by the Boston Bowel Preparation Scale, procedure delays, and length of hospital stay. We additionally evaluated the groups' demographics and patient-level factors. A total of 459 inpatient colonoscopies were evaluated over a 16-month period. The intervention group consisted of 227 inpatient colonoscopies, while the control group consisted of 232. The intervention group showed superior Boston Bowel Preparation Scale score and decreased length of hospital stay. The number of adequate bowel preparations increased in the intervention group when compared to the control group from 77% to 86%. The creation of an EMR-based order set is a low-cost and sustainable action that can be easily implemented throughout a hospital system.

Background/Aims: Presently, there is paucity of information about clinical predictors, especially esophageal motor abnormalities, for long segment Barrett's esophagus (LSBE) as compared with short segment Barrett's esophagus (SSBE). The aims of this study are to compare the frequency of esophageal function abnormalities between patients with LSBE and those with SSBE and to determine their clinical predictors. Methods: This was a multicenter cohort study that included all patients with a diagnosis of BE who underwent high-resolution esophageal manometry. Motility disorders were categorized as hypercontractile disorders or hypocontractile disorders and their frequency was compared between patients with LSBE and those with SSBE. Multivariable logistic regression modeling was used to calculate the odds of being diagnosed with LSBE relative to SSBE for demographics, comorbidities, medication use, endoscopic findings, and the type of motility disorders. Results: A total of 148 patients with BE were identified, of which 89 (60.1%) had SSBE and 59 (39.9%) LSBE. Patients with LSBE had a significantly larger hiatal hernia and higher likelihood of erosive esophagitis than patients with SSBE (P = 0.002). Patients with LSBE had a significantly lower mean LES resting pressure, distal contractile integral, distal latency, and significantly higher failed swallows and hypocontractile motility disorders than those with SSBE (P < 0.05). Hiatal hernia and hypocontractile motility disorder increased the odds of LSBE by 38.0% and 242.0%, as opposed to SSBE. Conclusions: The presence of a hypocontractile motility disorder increased the risk for LSBE. Furthermore, the risk for LSBE was directly associated with the length of the hiatal hernia.
RESUMO
BACKGROUND: The development of guidelines by gastroenterology societies increasingly stresses evidence-based endoscopic practice. AIMS: We performed a systematic assessment to determine whether endoscopic video teaching platforms incorporate evidence-based educational strategies and methods in order to disseminate guideline-based endoscopic management strategies. METHODS: Platforms with a video component were systematically identified using the Google search engine, Apple and Android application stores, and searching four major gastroenterology society websites and three known platforms, to identify all relevant platforms. Two video samples from each teaching platform were reviewed independently by two authors and assessed for use of a priori defined principles of evidence-based medicine, as determined by consensus agreement and for the use of simulation. RESULTS: Fourteen platforms were included in the final analysis, and two videos from each were analyzed. One of the 14 platforms used simulation and incorporated evidence-based medicine principles consistently. Nine of the 14 platforms were not transparent in regard to citation. None of the platforms consistently cited the certainty of evidence or explained how evidence was selected. CONCLUSIONS: Education of guideline-based endoscopic management strategies using principles of evidence-based medicine is under-utilized in endoscopic videos. In addition, the use of cognitive simulation is absent in this arena. There is a paucity of evidence-based cognitive endoscopy simulators designed for fellows that incorporate systematic evaluation, and efforts should be made to create this platform.

BACKGROUND AND AIMS: In the digital era of evidence-based medicine, there is a paucity of video endoscopy teaching platforms that use evidence-based medicine principles, or that allow for cognitive simulation of endoscopic management strategies. We created a guideline-based teaching platform for fellows that incorporates these features, and tested it. METHODS: A pilot video module with embedded questions was drafted, and after incorporation of feedback from several attending gastroenterologists, an additional 2 modules were created. The embedded questions were designed to simulate cognitive management decisions as if the viewer were doing the endoscopy procedure in the video. A narrator explained the evidence behind the task being performed, and its certainty based on endoscopic guidelines. Quizzes and surveys were developed and administered to a sample of attendings and fellows who completed the video modules to test efficacy, usability, and likeability. RESULTS: Three video modules, named evidence-based endoscopy (EBE), incorporating low fidelity simulation, and utilizing evidence-based medicine principles, were created. Eight fellows and 10 attendings completed the video modules and all quizzes and surveys. Mean test scores improved from before to after completing the video modules (56% to 92%; mean difference = -35%; 95% confidence interval, 27%-47%). Surveys indicated that the product was viewed favorably by participants, and that there is a strong desire for this type of educational product. CONCLUSIONS: The EBE simulator is a unique, desirable, and effective educational platform based on evidence-based medicine principles that fills a gap in available tools for endoscopy education. Further studies are needed to assess whether EBE can aid in long-term knowledge retention and increase adherence to guideline recommendations.

BACKGROUND: Mounting evidence supports a mechanistic association between irritable bowel syndrome (IBS) symptoms and mast cell hyperactivity. Yet, association between IBS and mast cell disorders (MCDs) has not been studied. We examined this association using two large databases and verified with manual chart review. METHODS: The IBM Watson Health Explorys database (Somers, NY), an aggregate of electronic health record (EHR) data from over two dozen US healthcare systems, and Epic's SlicerDicer tool, a self-service tool containing de-identified data from the Epic EHR, were used to identify patients with IBS and MCDs. Patients with organic gastrointestinal disease or diseases associated with secondary mast cell hyperproliferation were excluded. Results were verified with manual chart review from two academic centers. KEY RESULTS: Up to 4% of IBS patients had a comorbid MCD. IBS was strongly associated with all MCDs. The strongest association was between IBS and mast cell activation syndrome (OR 16.3; 95% CI 13.1-20.3). Odds ratios for IBS+urticaria, IBS+idiopathic urticaria, IBS+non-malignant mastocytosis, and IBS+mast cell malignancy ranged from 4.5 to 9.9. Patients from each of these overlap cohorts were predominantly female, and the overlap occurred with all IBS subtypes. Thorough endoscopic evaluation and comorbid mood disorders and migraines are more common in the overlap cohorts than in IBS alone. CONCLUSIONS/INFERENCES: In a large US database encompassing >53 million patients over >20 years, patients with IBS are at least 4 times more likely to have a MCD than the general population. Further study of mast cell involvement in the pathogenesis of IBS is warranted.

INTRODUCTION: Teduglutide, a glucagon-like peptide-2 analog, is a novel therapy for intestinal failure that reduces need for parenteral support, especially in patients without a functional terminal ileum or colon. It can also predispose patients to accelerated progression of gastrointestinal (GI) malignancy and fluid overload. We demographically and clinically characterized American patients prescribed teduglutide. METHODS: The Explorys database is an aggregate of deidentified patient data from dozens of US healthcare systems. We used SNOMED classification to identify patients prescribed teduglutide from 2015 to 2019. Through the browse cohort feature we determined the demographics, postsurgical anatomy, comorbidities, and indication for teduglutide use among these patients. RESULTS: Of approximately 72 million patients, 170 were prescribed teduglutide. A large majority were female (70.6%). Most common etiologies of short-bowel syndrome were intestinal obstruction (52.9%) and Crohn's disease (41.2%). Common postsurgical anatomy included total colectomy (41.2%) and ileostomy. Common incident symptoms included abdominal pain (41.2%) and nausea (23.5%). Thirty (17.6%) patients were prescribed teduglutide despite comorbid heart failure, and 5.9% despite prior GI malignancy. A total of 11.8% of patients had a history of benign GI neoplasms before starting teduglutide. A total of 5.9% of patients had posttreatment formation of colon polyps. CONCLUSION: In a large American database, the teduglutide prescription is rare. Only a minority have postsurgical anatomy associated with the most robust response to teduglutide. Serious adverse events appear rare, but a substantial number of patients are at risk for adverse effects because of the presence of comorbid heart failure or GI neoplasm.

BACKGROUND: Despite advances in the medical management of inflammatory bowel disease (IBD), a subset of patients may require extensive surgery, leading to short-bowel syndrome/intestinal failure requiring long-term home parenteral nutrition (PN) or customized intravenous fluid (IVF) support. Our aim was to further define the characteristics of IBD patients requiring home PN/IVF. METHODS: This is an observational study from a prospective IBD research registry. Patients receiving long-term home PN/IVF support during 2009-2015 were identified and compared with remaining IBD patients. Demographics, surgical history, smoking, narcotic use, IBD treatment, healthcare charges, and presence of biomarkers were reviewed. The IBD-PN group was stratified into 3 groups based on median healthcare charges. RESULTS: Of 2359 IBD patients, there were 25 (1%, 24 with Crohn's disease) who required home PN/IVF, and 250 randomly selected IBD patients matched for disease type formed the control population. Median duration of PN use was 27 months (interquartile range, 11-66). PN use was significantly associated with smoking, narcotic use, IBD-related operations, and lower quality-of-life scores. Among IBD-PN patients, 7 of 25 (28%, 3 after use of teduglutide) were able to successfully discontinue this modality. Median healthcare charges in the IBD-PN group were $51,456 annually. Median charges in the controls were $3427. Period prevalence mortality was 11.5% in IBD-PN and 3.8% in controls. CONCLUSIONS: IBD patients requiring long-term home PN/IVF support are a small minority in the present era of immunomodulator/biologic therapy. These refractory patients have a 15-fold increase in annual median healthcare charges compared with control IBD patients.

Various esophageal functional abnormalities have been described in patients with Barrett's esophagus (BE). A significantly higher esophageal acid exposure especially in the supine position has been documented in BE, as compared with the other gastroesophageal reflux disease phenotypes. In addition, weakly acidic reflux and duodenogastroesophageal reflux are more common in BE patients. The presence of Barrett's mucosa reduces esophageal mucosal impedance, occasionally to a level that prevents detection of reflux episodes. Reduced amplitude contractions and lower esophageal sphincter basal pressure are more common in BE patients as compared with the other gastroesophageal reflux disease groups. Ineffective esophageal motility is the most commonly defined motor disorder in BE. Reduced chemoreceptor and mechanoreceptor sensitivity to acid and balloon distention, respectively, have been suggested to explain lack or significantly less reports of reflux-related symptoms by BE patients.

Docetaxel and cyclophosphamide (TC) is a widely used breast cancer adjuvant regimen. We sought to compare the rates of febrile neutropenia (FN) between patients receiving no primary prophylaxis (PP) and those receiving PP with either granulocyte-colony stimulating factor (G-CSF) or antibiotics. We also analyzed cost-effectiveness of TC with and without either G-CSF or antibiotics. Charts were reviewed of all 340 patients who received adjuvant TC between January 2008 and December 2012 at two major cancer centers. Rates of FN in the three groups - no PP, PP with G-CSF and PP with antibiotics were compared. A Markov model was constructed comparing cost-effectiveness of PP with G-CSF, PP with antibiotics, and secondary prophylaxis (SP) with G-CSF after an episode of FN in a previous cycle. Costs were based on actual resource utilization and supplemented by the published literature, adjusted to 2012 Canadian dollars. Of the 73 (21%) patients who did not receive any PP, 23 (32%) of patients developed FN. Of the 192 (57%) patients receiving PP with G-CSF alone, only two (1%; p < 0.0001) developed FN; and of the 53 (16%) receiving PP with antibiotics alone, six (11%; p < 0.01) developed FN. From a cost-standpoint, PP with G-CSF was less cost-effective than PP with antibiotics. The rate of FN with TC chemotherapy exceeds 30%, and American Society of Clinical Oncology guidelines recommend PP with G-CSF in this situation. PP with antibiotics is more cost-effective, and is a reasonable option in resource-limited settings or for patients who decline or do not tolerate G-CSF.

Therapies for prostate cancer based on Fas (CD95) modulation have been under active development at the preclinical stage using immortalized cell lines. To address clinical applicability, the potential of 11 cultures of primary prostate cancer cells to be killed by Fas-mediated apoptosis was investigated. In addition, the effect of the chemotherapeutic agents mitoxantrone and docetaxel on this killing was determined. Apoptosis was induced in patient-derived, primary prostate cancer cells using effector cells engineered by recombinant lentivirus infection to express Fas ligand (FasL) and measured by 51Cr release assays. All cultured prostate cells were found to undergo Fas-mediated killing; cytotoxicity ranged from 12% to 87% after 6 h. These cells were significantly more sensitive to FasL-mediated killing than PC-3 cells. The basal expression of Fas or the expression of five inhibitors of apoptosis (c-FLIP, survivin, cellular inhibitors of apoptosis protein 1 and 2, and bcl-2) was not found to correlate with susceptibility to Fas-mediated killing. Both mitoxantrone and docetaxel were able to induce Fas receptor expression on primary prostate cancer cells, which translated into a 1.5- to 3-fold enhancement of apoptosis mediated by FasL. Whereas mitoxantrone increased the Fas-induced apoptotic response of all cultured prostate cells tested, docetaxel pretreatment was found to preferentially enhance the killing of bcl-2-expressing cells. These findings show that cultured primary prostate cancer cells are sensitive to Fas-mediated apoptosis. Furthermore, the incidence of apoptosis was found to be improved by combining Fas-mediated therapy with standard chemotherapeutic agents. These findings may have significant implications for prostate cancer therapy.
