Assessing the Value of Endoscopy Simulator Modules Designed to Prepare Residents for the Fundamentals of Endoscopic Surgery Examination.

BACKGROUND: The Fundamentals of Endoscopic Surgery examination is required for all general surgery residents. The test modules are not available for practice before the examination; however, similar modules are commercially available. OBJECTIVE: This study aims to determine which modules are most valuable for resident training and preparation for the examination by evaluating which correlates best with experience level. DESIGN: This was a single-institution study. SETTING: A virtual reality endoscopy simulator was utilized. PARTICIPANTS: General surgery residents and faculty endoscopists performed endoscopy simulator modules (Endobasket 2, Endobubble 1 and 2, Mucosal Evaluation 2, and Basic Navigation) designed to prepare residents for the Fundamentals of Endoscopic Surgery examination. Residents were assigned into junior and senior groups based on the completion of a dedicated endoscopy rotation. MAIN OUTCOME MEASURES: The primary outcomes measured were the mean time to completion, mean number of balloons popped, and mean number of wall hits for the 3 groups. RESULTS: A total of 21 junior residents, 11 senior residents, and 3 faculty participated. There were significant differences among groups in the mean time to completion for the Endobasket, Endobubble, and Mucosal Evaluation modules. The modules that correlated best with experience level were Endobubble 2 and Mucosal Evaluation 2. For Endobubble 2, juniors were slower than seniors, who were in turn slower than faculty (junior 118.8 ± 20.55 seconds, senior 100.3 ± 11.78 seconds, faculty 87.67 ± 2.848 seconds; p < 0.01). Juniors popped fewer balloons than seniors, who popped fewer balloons than faculty (junior 9.441 ± 3.838, senior 15.62 ± 4.133, faculty 28.78 ± 1.712; p < 0.001). For Mucosal Evaluation 2, juniors were slower than seniors, who were in turn slower than faculty (junior 468.8 ± 123.5 seconds, senior 368.6 ± 63.42 seconds, faculty 233.1 ± 70.45 seconds; p < 0.01). LIMITATIONS: Study residents have not completed the Fundamentals of Endoscopic Surgery examinations, so correlation with examination performance is not yet possible. CONCLUSIONS: Performance on Endobasket, Endobubble, and Mucosal Evaluation correlated well with experience level, providing benchmarks for each level to attain in preparation for the Fundamentals of Endoscopic Surgery examination.

In Search of the Ideal Promotility Agent: Optimal Use of Currently Available Promotility Agents for Nutrition Therapy of the Critically Ill Patient.

PURPOSE OF REVIEW: Enteral nutrition therapy is essential in the management of critically ill patients. Prokinetic agents have been used successfully to aid in the delivery of nutrition and improve feeding tolerance in patients in the intensive care unit (ICU). The aim of this report is to review the existing promotility agents available for use in the critically ill as well as outline the role of potential investigative drugs in order to provide a guide to the management of this difficult and important clinical dilemma. RECENT FINDINGS: While no single currently available agent currently meets all of the desired goals in the critical care setting, there are an increasing number of available agents from which to choose including motilin receptor agonists, 5HT4 receptor agonists, D2 receptor antagonists, and Mu opioid receptor antagonists. We recommend a multifaceted approach to optimizing enteral nutrition in the critical care setting which should include the early, prophylactic use of promotility agents and should focus on the management of reversible causes of impaired gastrointestinal motility.

Can Nutritional Assessment Tools Predict Response to Nutritional Therapy?

Traditional tools and scoring systems for nutritional assessment have focused solely on parameters of poor nutritional status in the past, in an effort to define the elusive concept of malnutrition. Such tools fail to account for the contribution of disease severity to overall nutritional risk. High nutritional risk, caused by either deterioration of nutritional status or greater disease severity (or a combination of both factors), puts the patient in a metabolic stress state characterized by adverse outcome and increased complications. Newer scoring systems for determining nutritional risk, such as the Nutric Score and the Nutritional Risk Score-2002 have created a paradigm shift connecting assessment and treatment with quality outcome measures of success. Clinicians now have the opportunity to identify high risk patients through their initial assessment, provide adequate or sufficient nutrition therapy, and expect improved patient outcomes as a result. These concepts are supported by observational and prospective interventional trials. Greater clinical experience and refinement in these scoring systems are needed in the future to optimize patient response to nutrition therapy.

Adenoma detection rate increases with each decade of life after 50 years of age.

BACKGROUND: The adenoma detection rate (ADR) has recently been used as a quality measure for screening colonoscopy. We hypothesize that the ADR will increase with each decade of life after 50 years of age. OBJECTIVE: The aim of this study was to define age-based goals for the ADR and advanced neoplasia to improve the quality of colonoscopy. METHODS: Using the Clinical Outcomes Research Initiative database, we identified patients who underwent screening colonoscopy between 2005 and 2006. Pathology of polyp findings was reviewed, and the ADR and the prevalence of advanced neoplasia were calculated based on age and sex. RESULTS: A total of 7756 polypectomies (44.9%) were performed on 17,275 patients between 2005 and 2006. Of these polyps, 56.3% (4363) were adenomas or more advanced lesions. The ADR was higher in men than women and increased with age. The ADR in men younger than age 50 was 24.7 (95% CI, 18.2-31.2); for those 50 to 59 years of age, it was 27.8 (95% CI, 26.5-29.1); for those 60 to 69 years of age, it was 33.6 (95% CI, 31.7-35.4); for those 70 to 79 years of age, it was 34.3 (95% CI, 31.5-37.1); and for those older than 80 years of age, it was 40.0 (95% CI, 32.9-47.1). The ADR in women younger than 50 years old was 12.6 (95% CI, 6.8-18.4); in those 50 to 59 years of age, it was 17.0 (85% CI, 15.9-18.1); for those 60 to 69 years of age, it was 22.4 (95% CI, 20.8-24.0); for those 70 to 79 years of age, it was 26.1 (95% CI, 23.7-28.5); and for those older than 80 years of age, it was 26.9 (95% CI, 21.4-32.5). LIMITATIONS: The Clinical Outcomes Research Initiative database offers access to demographic information as well as endoscopy and pathology data, but there is limited clinical information about patients in the database. CONCLUSION: The ADR, and, importantly, the rate of advanced neoplasia increased with each decade of life after the age of 50 and are higher in men than women in each decade of life.

Multidisciplinary care for people with Parkinson's disease: the new kids on the block!

INTRODUCTION: Parkinson's disease (PD) is a chronic multisystem disorder that causes a wide variety of motor and non-motor symptoms. Over time, the progressive nature of the disease increases the risk of complications such as falls and loss of independence, having a profound impact on quality of life. The complexity and heterogeneity of symptoms therefore warrant a holistic, multidisciplinary approach. Specific healthcare professionals, e.g. the movement disorders neurologist and the PD nurse specialist, are considered essential members of this multidisciplinary team. However, with our increasing knowledge about different aspects of the disease, other disciplines are also being recognized as important contributors to the healthcare team. Areas covered: The authors describe a selection of these relatively newly-recognized disciplines, including the specialist in vascular medicine, gastroenterologist, pulmonologist, neuro-ophthalmologist, urologist, geriatrician/elderly care physician, palliative care specialist and the dentist. Furthermore, they share the view of a person with PD on how patients and caregivers should be involved in the multidisciplinary team. Finally, they have included a perspective on the new role of the movement disorder neurologist, with care delivery via 'tele-neurology'. Expert commentary: Increased awareness about the potential role of these 'new' professionals will further improve disease management and quality of life of PD patients.

Gender Differences in Publication Productivity, Academic Rank, and Career Duration Among U.S. Academic Gastroenterology Faculty.

PURPOSE: Female representation in academic medicine is increasing without proportional increases in female representation at senior ranks. The purpose of this study is to describe the gender representation in academic gastroenterology (GI) and compare publication productivity, academic rank, and career duration between male and female gastroenterologists. METHOD: In 2014, the authors collected data including number of publications, career duration, h-index, and m-index for faculty members at 114 U.S. academic GI programs. RESULTS: Of 2,440 academic faculty, 1,859 (76%) were men and 581 (24%) were women. Half (50%) of men held senior faculty position compared with 29% of women (P < .001). Compared with female faculty, male faculty had significantly (P < .001) longer careers (20 vs. 11 years), more publications (median 24 [0-949] vs. 9 [0-438]), and higher h-indices (8 vs. 4). Higher h-index correlated with higher academic rank (P < .001). The authors detected no difference in the h-index between men and women at the same rank for professor, associate professor, and instructor, nor any difference in the m-index between men and women (0.5 vs. 0.46, respectively, P = .214). CONCLUSIONS: A gender gap exists in the number and proportion of women in academic GI; however, after correcting for career duration, productivity measures that consider quantity and impact are similar for male and female faculty. Women holding senior faculty positions are equally productive as their male counterparts. Early and continued career mentorship will likely lead to continued increases in the rise of women in academic rank.

Lipid rescue of massive verapamil overdose: a case report.

INTRODUCTION: Massive intentional verapamil overdose is a toxic ingestion which can cause multiorgan system failure and has no currently known antidote. CASE PRESENTATION: The patient is a 41-year-old Caucasian woman who ingested 19.2 g of sustained release verapamil in a suicide attempt. Our patient became hypotensive requiring three high-dose vasopressors to maintain arterial pressure. She also developed acute respiratory failure, bradycardic ventricular rhythm necessitating continuous transvenous pacing, and anuric renal failure. Our patient was treated with intravenous calcium, bicarbonate, hyperinsulinemic euglycemic therapy and continuous venovenous hemodialysis without success. On the fourth day after hospital admission continuous intravenous lipid therapy was initiated. Within three hours of beginning lipid therapy, our patient's vasopressor requirement decreased by half. Within 24 hours, she was on minimal vasopressor support and regained an underlying junctional rhythm. After three days of lipid infusion, she no longer required inotropic agents to maintain blood pressure or pacing to maintain stable hemodynamics. CONCLUSIONS: Intravenous fat emulsion therapy may be an effective antidote for massive verapamil toxicity.
