Gender Disparity in Academic Gastroenterology: Beginning of the End of the Underrepresentation of Women?

BACKGROUND: Though there are an increasing number of female medical graduates, women remain underrepresented in academic medicine. There have been several reasons to explain this gender disparity, including marital status, number of children, number of hours worked, job flexibility, perceptions of women as inferior leaders, gender bias, sexual harassment, and unsupportive academic climates. AIMS: This study aimed to investigate the relationship between scholarly productivity and the representation of female gastroenterologists in academia. Specifically, scholarly productivity measured by the h-index and academic rank were explored to determine if there were gender disparities in academic productivity and rank in gastroenterology. METHODS: Gastroenterology departmental listings were obtained from the Fellowship and Residency Interactive Database of the American Medical Association. The Scopus database was used to record each physician's h-index. Statistical analyses were conducted with Wilcoxon rank-sum test, which compared matched samples by academic rank, and ANOVA tests, which compared multiple academic ranks. RESULTS: Out of 1703 academic gastroenterologists, women account for 25% of academic physicians. Women have statistically lower h-indices at the level of Assistant Professor (p = 0.0012), and at the level of Chair (p = 0.01). There was no difference in h-indices between male and female at the rank of Associate Professor and Professor. CONCLUSIONS: While these results mirror patterns appreciated in other fields of medicine, the results at the rank of Chair may suggest that despite the lower h-index compared to their male counterparts, females are perceived as having strong inherent leadership skills outside of academic productivity that are also conducive to leading a department and may be contributing to their rise to Chair.

Management of locally advanced rectal cancer in the elderly: a critical review and algorithm.

Colorectal cancer incidence and death rates have been declining over the past 10 years. However, it remains the second leading cause of death in men ages 60-79 and the third leading cause of death in men over 80 and in women over 60 years old. However, there is little data specific to the treatment of the elder patient, since few of these patients are included in trials. With the advent of improved therapies, there are many alternative options available. Still, no definitive consensus or guidelines have been defined for this particular patient population. The goal of this study is to review the literature on the management of rectal cancer in the elderly and to propose treatment algorithms to help the oncology team in treatment decision-making.

Targeting Small Bowel Receptors to Treat Constipation and Diarrhea.

BACKGROUND: The options for the treatment of diarrhea and constipation are evolving as emerging therapies target small bowel receptors. The goal of this review is to discuss small bowel receptors involved in intestinal absorption, secretion, and motility. The review highlights therapies already approved or currently being studied for the modulation of these receptors. METHODS: The articles cited in this review focus on the molecular level of pathways involved in diarrhea and constipation, and highlight the respective pharmacotherapies. RESULTS: The majority of the studies in the current literature investigate the effects of both the small and large intestine receptors on diarrhea and constipation. There are fewer studies that isolate the effects of these receptors solely on the small bowel, and focusing more on the receptors found distinctly in the small intestine may be an area of interest for future studies as this can inspire more targeted therapies.

Colorectal cancer screening patient education materials-how effective is online health information?

PURPOSE: Patients screened for colorectal cancer (CRC) frequently turn to the Internet to improve their understanding of tests used for detection, including colonoscopy, flexible sigmoidoscopy, fecal occult blood test (FOBT), and CT colonography. It was of interest to determine the quality and readability levels of online health information. METHODS: The screening tools were googled, and the top 20 results of each test were analyzed for readability, accessibility, usability, and reliability. The 80 articles excluded scientific literature and blogs. We used ten validated readability scales to measure grade levels, and one-way ANOVA and Tukey's honestly statistical different (HSD) post hoc analyses to determine any statistically significant differences among the four diagnostic tests. The LIDA tool assessed overall quality by measuring accessibility, usability, and reliability. RESULTS: The 80 articles were written at an 11.7 grade level, with CT colonography articles written at significantly higher levels than FOBT articles, F(3, 75) = 3.07, p = 0.033. LIDA showed moderate percentages in accessibility (83.9 %), usability (73.0 %), and reliability (75.9 %). CONCLUSIONS: Online health information about CRC screening tools are written at higher levels than the National Institute of Health (NIH) and American Medical Association (AMA) recommended third to seventh grade levels. More patients could benefit from this modality of information if it were written at a level and quality that would better facilitate understanding.

Gastrointestinal Dysmotility in the Elderly.

The number of persons 60 years and older has increased 3-fold between 1950 and 2000. Aging alone does not greatly impact the gastrointestinal (GI) tract. Digestive dysfunction, including esophageal reflux, achalasia, dysphagia, dyspepsia, delayed gastric emptying, constipation, fecal incontinence, and fecal impaction, is a result of the highly prevalent comorbid conditions and the medications with which those conditions are treated. A multidisciplinary approach with the expertise of a geriatrician, gastroenterologist, neurologist, speech pathologist, and physical therapist ensures a comprehensive functional and neurological assessment of the older patient. Radiographic and endoscopic evaluation may be warranted in the evaluation of the symptomatic older patient with consideration given to the risks and benefits of the test being used. Treatment of the digestive dysfunction is aimed at improving health-related quality of life if cure cannot be achieved. Promotion of healthy aging, treatment of comorbid conditions, and avoidance of polypharmacy may prevent some of these digestive disorders. The age-related changes in GI motility, clinical presentation of GI dysmotility, and therapeutic principles in the symptomatic older patient are reviewed here.

Management of Inflammatory Bowel Disease in the Elderly.

OPINION STATEMENT: A substantial and growing proportion of patients with inflammatory bowel disease (IBD) are elderly, and these patients require tailored treatment strategies. However, significant challenges exist in the management of this population due to the paucity of data. Establishing the initial diagnosis and assessing the etiology of future symptoms and flares can be challenging as several other prevalent diseases can masquerade as IBD, such as ischemic colitis, diverticular disease, and infectious colitis. Important pharmacologic considerations include reduced glomerular filtration rate and drug-drug interactions in the elderly. No drug therapy is absolutely contraindicated in this population; however, special risk and benefit assessments should be made. Older patients are more susceptible to side effects of steroids such as delirium, fractures, and cataracts. Budesonide can be an appropriate alternative for mild to moderate ulcerative colitis (UC) or Crohn's disease (CD) as it has limited systemic absorption. Pill size and quantity, nephrotoxicity, and difficulty of administration of rectal preparations should be considered with 5-aminosalicylic (5-ASA) therapy. Biologics are very effective, but modestly increase the risk of infection in a susceptible group. Based on their mechanisms, integrin receptor antagonists (e.g., vedolizumab) may reduce these risks. Use of antibiotics for anorectal or fistulizing CD or pouchitis in UC increases the risk of Clostridium difficile infection. Pre-existing comorbidities, functional status, and nutrition are important indicators of surgical outcomes. Morbidity and mortality are increased among IBD patients undergoing surgery, often due to postoperative complications or sepsis. Elderly adults with IBD, particularly UC, have very high rates of venous thromboembolism (VTE). Colonoscopy appears safe, but the optimal surveillance interval has not been well defined. Should the octogenarian, nonagenarian, and centurion undergo colonoscopy? The length of surveillance should likely account for the individual's overall life expectancy. Specific health maintenance should emphasize administering non-live vaccines to patients on thiopurines or biologics and regular skin exams for those on thiopurines. Smoking cessation is crucial to overall health and response to medical therapy, even among UC patients. This article will review management of IBD in the elderly.

Constipation in Elderly Patients with Noncancer Pain: Focus on Opioid-Induced Constipation.

Constipation is a common and often debilitating condition in the elderly, which may be caused by underlying disease conditions, structural abnormalities in the bowel, and a variety of medications such as anticholinergics, antidepressants, and opiates. In this review, we focus on opioid-induced constipation (OIC), which is often underrecognized and undertreated in the elderly. When opioid therapy is initiated, healthcare providers are encouraged to evaluate risk factors for the development of constipation as part of a thorough patient history. To this end, the patient assessment should include the use of validated instruments, such as the Bristol Stool Scale and Bowel Function Index, to confirm the diagnosis and provide a basis for evaluating treatment outcomes. Healthcare providers should use a stepwise approach to the treatment of OIC in the elderly. Conventional laxatives are a first-line option and considered well tolerated with short-term use as needed; however, evidence is lacking to support their effectiveness in OIC. Moreover, because of the risk of adverse events and other considerations, such as chewing difficulties and swallowing disorders, conventional oral laxatives may be inappropriate for the treatment of OIC in the elderly. Thus, the availability of new pharmacologic agents such as the peripherally acting µ-opioid receptor antagonists methylnaltrexone and naloxegol, which target the underlying causes of OIC, and the secretagogue lubiprostone may provide more effective treatment options for elderly patients with OIC.

Clinical Challenges of Fecal Incontinence in the Elderly.

OPINION STATEMENT: Fecal incontinence (FI) is underreported, yet it is quite commonly experienced by the elderly patient. FI confers a significant direct and indirect burden on patients, their caregivers, and the health-care system. Due to the presence of multiple comorbid medical conditions in patients over 65 years of age and the number of medications taken by elderly patients, FI management poses several challenges to the treating physician. We emphasize the importance of a comprehensive history and physical exam with specific attention to diet, physical activity, cognitive function, medications, and comorbidities specific to patients in this age group. Symptomatic conservative therapy should be the first step in management. Evaluation of the underlying pathology causing FI and more invasive treatments should be considered in selected patients who are cognitively intact and can tolerate these procedures.

Unreported complication of Bravo pH capsule dislodged into the pyriform sinus.

We report an unexpected, previously unreported complication of Bravo pH capsule dislodgement. During Bravo pH testing of a 44-year-old man with gastroesophageal reflux disease, we were unable to endoscopically visualize the capsule attached to the esophageal wall after deployment. After multiple attempts to detect the capsule, it was visualized in the left pyriform sinus. As there was significant risk for pulmonary dislodgement, ENT and pulmonary physicians were immediately consulted to review options for safe removal. Ultimately, ENT successfully retrieved the capsule with a foreign body removal forceps. The Bravo pH test is generally a well-tolerated diagnostic tool used to confirm the presence of abnormal esophageal acid reflux. While few complications have been reported, technical difficulties can occur, including poor data reception, misplacement, and early dislodgement. Rarely, more serious complications can occur, ranging from esophageal wall trauma to capsule aspiration. Gastroenterologists performing this procedure should be aware of the low, but non-trivial, risk of complications.

Review of gastroesophageal reflux disease (GERD) in the diabetic patient.

This article reviews the known pathophysiological mechanisms of comorbid gastroesophageal reflux disease (GERD) in the diabetic patient, discusses therapeutic options in care, and provides an approach to its evaluation and management. We searched for review articles published in the past 10 years through a PubMed search using the filters diabetes mellitus, GERD, pathophysiology, and management. The search only yielded a handful of articles, so we independently included relevant studies from these review articles along with related citations as suggested by PubMed. We found diabetic patients are more prone to developing GERD and may present with atypical manifestations. A number of mechanisms have been proposed to elucidate the connection between these two diseases. Studies involving treatment options for comorbid disease suggest conflicting drug-drug interactions. Currently, there are no published guidelines specifically for the evaluation and management of GERD in the diabetic patient. Although there are several proposed mechanisms for the higher prevalence of GERD in the diabetic patient, this complex interrelationship requires further research. Understanding the pathophysiology will help direct diagnostic evaluation. In our review, we propose a management algorithm for GERD in the diabetic patient.

Esophageal pathology: a brief guide and atlas.

This article contains a brief atlas for esophageal dysphagia, with an emphasis on endoscopic evaluation. Dysphagia refers to an abnormality with food propulsion, and it may be caused by oropharyngeal or esophageal disorders. Radiological modalities, endoscopy, and manometry play an important role in both the diagnosis and management of esophageal disorders.

Fecal incontinence in the elderly: FAQ.

Fecal incontinence (FI) is a common gastrointestinal (GI) complaint in patients aged 65 years and older. This evidence-based review article discusses the epidemiology, pathophysiology, evaluation, and management of FI in the geriatric population. We emphasize aging-related changes leading to and impacting evaluation and treatment of this symptom while incorporating the core geriatric principles of functional status and management aligned with patient preference and goals of care.

Informed consent in the older adult: OSCEs for assessing fellows' ACGME and geriatric gastroenterology competencies.

OBJECTIVES: The American Gastroenterological Association fellowship curriculum identifies geriatric components for gastroenterology (GI) training; however, few tools are available for this purpose. Using an objective structured clinical examination (OSCE), we aimed to assess ACGME competencies of communication, professionalism, and geriatric-specific patient care among GI fellows. METHODS: We developed an informed-consent case involving a geriatric patient who needs surveillance colonoscopy. We used a validated faculty skills checklist to rate fellows across three competency domains. Fifteen fellows from four GI training programs participated. RESULTS: Although the fellows excelled at communication and professionalism, only 51% excelled at geriatric-specific patient-care skills. Fellows were least likely to demonstrate collaboration with the patient, to assess patient understanding, and to explain the limits of the test. Communication and geriatric-specific skills were correlated. CONCLUSIONS: OSCEs are a feasible method for assessing geriatric-related ACGME competencies for fellows. The results highlight the need for curriculum development.

Observing handoffs and telephone management in GI fellowship training.

OBJECTIVES: Gastroenterology (GI) training programs are mandated to teach fellows interpersonal communication and professionalism as basic competencies. We sought to assess important skill sets used by our fellows but not formally observed or measured: handoffs, telephone management, and note writing. We designed an Observed Standardized Clinical Examination (OSCE) form and provided the faculty with checklists to rate fellows' performance on specific criteria. METHODS: We created two new scenarios: a handoff between a tired overnight senior fellow on call and a more junior fellow, and a telephone management case of an ulcerative colitis flare. Fellows wrote a progress notes documenting the encounters. To add educational value, we gave the participants references about handoff communication. Four OSCE stations-handoff communication, telephone management, informed consent, and delivering bad news-were completed by fellows and observed by faculty. RESULTS: Eight faculty members and eight fellows from four GI training programs participated. All the fellows agreed that handoffs can be important learning opportunities and can be improved if they are structured, and that handoff skills can improve with practice. CONCLUSIONS: OSCEs can serve as practicums for assessing complex skill sets such as handoff communication and telephone management.

Teaching the competencies: using observed structured clinical examinations for faculty development.

OBJECTIVES: Gastroenterology (GI) training programs must develop the teaching skills of their faculty and provide feedback to their fellows. Many faculty feel uncomfortable offering feedback or identifying specific areas for improvement to the fellows. We developed an Observed Structured Clinical Exam (OSCE) to assess fellows' skills and provided faculty with specific criteria to rate the fellows' performance. We propose that OSCEs can serve as tools for faculty development in delivering effective feedback. METHODS: Faculty completed a Web-based training module and received written guidelines on giving feedback. Four OSCE stations were completed by each fellow with faculty using standardized checklists to assess the fellows' skills. Afterwards, faculty rated each program component and assessed their comfort level with feedback. RESULTS: Eight faculty members and 10 fellows from 5 GI training programs in NYC participated. 100% of the faculty agreed that feedback is an important learning tool, should include the learner's self-assessment, and that feedback skills could improve with practice. Compared to faculty skills prior to the program, 87.5% of the faculty agreed that they focused more on specific behaviors and 75% agreed that giving negative feedback was now easier. CONCLUSIONS: OSCEs can serve as practicums for faculty development in giving constructive feedback.

Treatment of acute colonic pseudo-obstruction with tegaserod.

Acute colonic pseudo-obstruction is characterized by symptoms, signs and radiologic appearance of large bowel obstruction in the absence of a true mechanical obstruction. Several pharmacologic treatments have been proposed. We present a case of a patient with Guillain-Barré syndrome complicated by acute colonic pseudo-obstruction, who had a clinical response to tegaserod, a partial 5-hydroxytryptamine type-4 agonist. 5-Hydroxytryptamine type 4 agonists may be an option in the treatment of acute colonic pseudo-obstruction.

Is there physician bias against eliciting affective qualities of pain?

GOALS: The purpose of this study is to determine the weight given to each of 3 pain dimensions by physicians who assess patients' pain experiences. BACKGROUND: Pain is a subjective experience that has profound impact on the quality of life. The 101-Multidimensional Affect and Pain Survey (101-MAPS) is currently the only available instrument that takes into account all 3 validated dimensions of pain by classifying 101 items into "superclusters" of sensory pain, suffering, and well-being. STUDY: Fourteen gastroenterologists, 11 internists, and 11 medicine residents from 2 teaching hospitals rated the items on the 101-MAPS based on their perception of the items' relevance to pain in gastrointestinal diseases, on a scale of 0 (least relevant) to 5 (most relevant). RESULTS: Of the 101 items in the MAPS rated by gastroenterologists, 25 items received a median rating of 4 or above. Of these, 23 were selected from the 57 items in the sensory pain supercluster (40%) and only 1 item each from the 26 in the suffering (3.8%), and the 18 in the well-being (5.5%) dimensions. These proportions were significantly lower for the suffering (P<0.01) and well-being (P<0.05) superclusters than for the sensory pain dimension. CONCLUSIONS: These findings suggest a bias among physicians toward sensory and against affective qualities when eliciting patients' pain experiences. The results also suggest that this bias is found as early as residency training and persists among specialists.

Teaching the competencies: using objective structured clinical encounters for gastroenterology fellows.

BACKGROUND AIMS: Objective structured clinical encounters (OSCEs) are used widely to educate and assess the competence of medical students and residents; they generally are absent from fellowship training. The Accreditation Council for Graduate Education has cited OSCEs as a best practice for assessing the 6 core competencies. This article reports on the use of an OSCE to assess the competence of second-year gastroenterology fellows in the difficult-to-assess core competencies: interpersonal and communication skills and professionalism. METHODS: We developed a 4-station, faculty-observed OSCE with 4 standardized patients. Information gathering, relationship development, patient education, and counseling skills were assessed. Professionalism skills assessed included obtaining informed consent, delivering bad news, managing difficult situations, and showing interdisciplinary respect. In each station, faculty and standardized patients completed an 18- to 24-item checklist evaluating fellows' performance and provided feedback to the fellows. Nine fellows and 5 faculty from 4 gastroenterology training programs in NYC participated. RESULTS: Fellows and faculty generally highly rated the realism of the OSCE and favorably rated the OSCE for its difficulty and their overall experience. Across all cases, fellows were rated as receiving "well dones" for 56.4% of the communication items (SD, 18.3%) and for 79.1% of the professionalism items (SD, 16.4%). CONCLUSIONS: Integrating OSCEs into gastroenterology fellowship training may help enhance communication skills and prepare fellows for dealing with difficult clinical situations and provides mechanisms for constructive feedback. OSCEs developed collaboratively can assist in program self-evaluation and reduce costs by sharing resources, in addition to fulfilling Accreditation Council for Graduate Education mandates.

Complications of and controversies associated with percutaneous endoscopic gastrostomy: report of a case and literature review.

CONTEXT: Percutaneous endoscopic gastrostomy (PEG) is one of the most commonly performed gastrointestinal procedures, despite absence of benefit in many patients and risks associated with the procedure. Increased education of primary care physicians about the shortcomings of PEG may allow for better selection of patients to be referred for PEG placement. EVIDENCE ACQUISITION: We performed a comprehensive literature review by searching PUBMED using the search headings percutaneous enteral gastrostomy, PEG, complications, dementia, stroke, dysphagia, malnutrition, and complications. We identified English language articles from 1980 onward. The highest quality data were considered to be randomized controlled trials although given the paucity of trials in this area, we used all of the various types of literature. EVIDENCE SYNTHESIS: We based the major conclusions of this review, where possible, on the most robust literature, namely, controlled trials. However, the majority of the available literature in this field is based on case series. We attempted to maximize the use of larger case series with longer term follow-up. Case reports were used only to report on rare complications where no other literature was available. CONCLUSIONS: Despite more than 30 years of experience with PEG, numerous questions remain regarding the utility of nutrition support in many of the clinical scenarios in which PEG placement is contemplated. There is a multitude of evidence that artificial nutrition does not improve outcome or quality of life in patients with dementia who have decreased oral intake. It is likely that ethical, moral, religious, and legal considerations of family members and caregivers play a role in the decision to place a PEG in a patient with dementia despite the medical evidence demonstrating lack of benefit.
