Low serum trypsinogen levels in chronic pancreatitis: Correlation with parenchymal loss, exocrine pancreatic insufficiency, and diabetes but not CT-based cambridge severity scores for fibrosis.

BACKGROUND: Chronic pancreatitis (CP) is a complex inflammatory disorder of the pancreas affecting acinar cells, duct cells, islet cells and inflammatory cells including fibrosis-producing stellate cells. Serum trypsinogen is a biomarkers of acinar cell function. AIM: To define the degree of correlation between low trypsinogen levels as a marker of acinar cell function and variable features of CP. METHODS: Serum samples from previously ascertained and well phenotyped case and control subjects from the North American Pancreatitis Study II (NAPS2) were used to measure serum trypsinogen levels in a commercial laboratory. Control samples were used to define normal ranges and compared with levels in CP patients with defined features. RESULTS: A final cohort of 279 CP patients and 262 controls from the NAPS2 studies were evaluated. In controls trypsinogen had a mean of 34.96 ng/ml and SD = 11.99. Cut-off values for low trypsinogen ranged from <20 to 10 ng/ml and very low trypsinogen at <10 ng/ml. Compared to controls, CP was associated with very low trypsinogen levels (p < 0.0001). Within CP, very low trypsinogen levels correlated with parenchymal loss (pancreatic surgery [p < 0.05]; atrophy with calcifications, [p < 0.001]), EPI (p < 0.01, trend p < 0.001) and diabetes (trend p < 0.01) but not CT-based criteria for fibrosis (pancreatic duct dilation, irregularity, strictures). CONCLUSIONS: Very low serum trypsinogen levels correlate with measures of acinar cell loss including surgical resection, atrophic-calcific CP, diabetes and functional symptoms EPI but not duct morphology criteria. Serum trypsinogen levels correlate with decreased acinar cell function and therefore have biomarker utility clinical management.

Association Between Endoscopist Personality and Rate of Adenoma Detection.

BACKGROUND & AIMS: There is significant variation among endoscopists in their adenoma detection rates (ADRs). We explored associations between ADR and characteristics of endoscopists, including personality traits and financial incentives. METHODS: We collected electronic health record data from October 2013 through September 2015 and calculated ADRs for physicians from 4 health systems. ADRs were risk-adjusted for differences in patient populations. Physicians were surveyed to assess financial motivations, knowledge and perceptions about colonoscopy quality, and personality traits. Of 140 physicians sent the survey, 117 responded. RESULTS: The median risk-adjusted ADR for all surveyed physicians was 29.3% (interquartile range, 24.1%-35.5%). We found no significant association between ADR and financial incentives, malpractice concerns, or physicians' perceptions of ADR as a quality metric. ADR was associated with the degree of self-reported compulsiveness relative to peers: among endoscopists who described themselves as much more compulsive, the ADR was 33.1%; among those who described themselves as somewhat more compulsive, the ADR was 32.9%; among those who described themselves as about the same as others, the ADR was 26.4%; and among those who described themselves as somewhat less compulsive, the ADR was 27.3%) (P = .0019). ADR was also associated with perceived thoroughness (much more thorough than peers, ADR = 31.5%; somewhat more, 31.9%; same/somewhat less, 27.1%; P = .0173). Physicians who reported feeling rushed, having difficulty pacing themselves, or having difficulty in accomplishing goals had higher ADRs. A secondary analysis found the same associations between personality and adenomas per colonoscopy. CONCLUSIONS: We found no significant association between ADR and financial incentives, malpractice concerns, or perceptions of ADR as a quality metric. However, ADRs were higher among physicians who described themselves as more compulsive or thorough, and among those who reported feeling rushed or having difficulty accomplishing goals.

Etiology and Treatment of Pain and Psychosocial Issues in Patients With Inflammatory Bowel Diseases.

There is increasing evidence that brain-gut interactions are altered during development of inflammatory bowel diseases (IBDs). Understanding the relationship between the neurobiology, psychological symptoms, and social ramifications of IBD can guide comprehensive care for the whole patient. The most common psychological conditions in patients with IBD are chronic abdominal pain, anxiety, and depression. We review the evidence-based data and rates of these conditions and their respective relationship to IBD and the diagnostic approaches to identify patients with these conditions. Different treatment options for pain and psychosocial conditions are discussed, and new models of team-based IBD care are introduced. Providing the health care provider with tools to diagnose and manage psychological conditions in patients with Crohn's disease or ulcerative colitis is necessary for their total care and should be part of quality-improvement initiatives.

Variation in Pathologist Classification of Colorectal Adenomas and Serrated Polyps.

OBJECTIVES: Endoscopist quality measures such as adenoma detection rate (ADR) and serrated polyp detection rates (SPDRs) depend on pathologist classification of histology. Although variation in pathologic interpretation is recognized, we add to the literature by quantifying the impact of pathologic variability on endoscopist performance. METHODS: We used natural language processing to abstract relevant data from colonoscopy and related pathology reports performed over 2 years at four clinical sites. We quantified each pathologist's likelihood of classifying polyp specimens as adenomas or serrated polyps. We estimated the impact on endoscopists' ADR and SPDR of sending their specimens to pathologists with higher or lower classification rates. RESULTS: We observed 85,526 colonoscopies performed by 119 endoscopists; 50,453 had a polyp specimen, which were analyzed by 48 pathologists. There was greater variation across pathologists in classification of serrated polyps than in classification of adenomas. We estimate the endoscopist's average SPDR would be 0.5% if all their specimens were analyzed by the pathologist in our sample with the lowest classification rate and 12.0% if all their specimens were analyzed by the pathologist with the highest classification rate. In contrast, the endoscopist's average ADR would be 28.5% and 42.4% if their specimens were analyzed by the pathologist with lowest and highest classification rate, respectively. CONCLUSIONS: There is significant variation in pathologic interpretation, which more substantially affects endoscopist SPDR than ADR.

Physician characteristics associated with higher adenoma detection rate.

BACKGROUND AND AIMS: Patients who receive a colonoscopy from a physician with a low adenoma detection rate (ADR) are at higher risk of subsequent colorectal cancer. It is unclear what drives the variation across physicians in ADR. We describe physician characteristics associated with higher ADR. METHODS: In this retrospective cohort study a natural language processing system was used to analyze all outpatient colonoscopy examinations and their associated pathology reports from October 2013 to September 2015 for adults age 40 years and older across physicians from 4 diverse health systems. Physician performance on ADR was risk adjusted for differences in patient population and procedure indication. Our sample included 201 physicians performing at least 30 colonoscopy examinations during the study period, totaling 104,618 colonoscopy examinations. RESULTS: The mean ADR was 33.2% (range, 6.3%-58.7%). Higher ADR was seen among female physicians (4.2 percentage points higher than men, P = .020), gastroenterologists (9.4 percentage points higher than nongastroenterologists, P < .001), and physicians with ≤9 years since their residency completion (6.0 percentage points higher than physicians who have had 27-51 years of practice, P = .004). CONCLUSIONS: Gastroenterologists, female physicians, and more recently trained physicians had higher performance in adenoma detection.

Endoscopist factors that influence serrated polyp detection: a multicenter study.

BACKGROUND: Serrated polyps are important colorectal cancer precursors that are variably detected during colonoscopy. We measured serrated polyp detection rate (SPDR) in a large, multicenter, cross-sectional study of colonoscopy quality to identify drivers of SPDR variation. METHODS: Colonoscopy and pathology reports were collected for a 2-year period (10/2013-9/2015) from four sites across the United States. Data from reports, including size, location, and histology of polyps, were abstracted using a validated natural language processing algorithm. SPDR was defined as the proportion of colonoscopies with ≥ 1 serrated polyp (not including hyperplastic polyps). Multivariable logistic regression was performed to determine endoscopist characteristics associated with serrated polyp detection. RESULTS: A total of 104 618 colonoscopies were performed by 201 endoscopists who varied with respect to specialty (86 % were gastroenterologists), sex (18 % female), years in practice (range 1 - 51), and number of colonoscopies performed during the study period (range 30 - 2654). The overall mean SPDR was 5.1 % (SD 3.8 %, range 0 - 18.8 %). In multivariable analysis, gastroenterology specialty training (odds ratio [OR] 1.89, 95 % confidence interval [CI] 1.33 - 2.70), fewer years in practice (≤ 9 years vs. ≥ 27 years: OR 1.52, 95 %CI 1.14 - 2.04)], and higher procedure volumes (highest vs. lowest quartile: OR 1.77, 95 %CI 1.27 - 2.46)] were independently associated with serrated polyp detection. CONCLUSIONS: Gastroenterology specialization, more recent completion of training, and greater procedure volume are associated with serrated polyp detection. These findings imply that both repetition and training are likely to be important contributors to adequate detection of these important cancer precursors. Additional efforts to improve SPDR are needed.

Management and outcomes of acute pancreatitis patients over the last decade: A US tertiary-center experience.

BACKGROUND/OBJECTIVES: Acute pancreatitis (AP) management remains largely supportive and can be challenging in patients with severe disease. This study aims to describe a ten-year US tertiary-center experience in managing AP patients. METHODS: Clinical management and outcomes of 400 prospectively enrolled AP patients stratified by the Revised Atlanta Classification were analyzed; trends in management between early (2004-2008) and late enrollment phase (2009-2014) were assessed. RESULTS: Fifty-two% of patients were classified as mild AP (MAP); moderately severe (MoAP) and severe (SAP) grades contained 23.5% and 24.5% of participants. Intravenous fluid administration during the first 24 h (MAP 3.7, MoAP 4.7, and SAP 4.8 L), need for ICU (6%, 23%, 93%), and nutritional support (7%, 51%, 90%) increased significantly with greater AP severity (p < 0.001). One hundred fifty five (39%) patients developed necrotizing AP, of which 41% received prophylactic antibiotics, and 44% underwent pancreatic drainage/debridement. Prophylactic antibiotics (58% vs. 27%) and interventions (63% vs. 27%) were noted more frequently in SAP than MoAP (p < 0.001). Enteral nutrition (18% vs. 30%) and minimally invasive pancreatic interventions (19% vs. 41%) were more commonly used in the late phase (p < 0.05). The overall median length of hospitalization was 7 days reaching 29 days in SAP group. Mortality was 5%; all deaths occurred in SAP group. CONCLUSIONS: This study provides an extensive report on clinical management of AP and its trends overtime. Pancreatic intervention is required in less than 50% of patients with necrotizing pancreatitis. Utilization of enteral nutrition and minimally invasive pancreatic interventions has been increasing over time.

Chronic pancreatitis: An international draft consensus proposal for a new mechanistic definition.

BACKGROUND: A definition of chronic pancreatitis (CP) is needed for diagnosis and distinguishing CP from other disorders. Previous definitions focused on morphology. Advances in epidemiology, genetics, molecular biology, modeling and other disciplines provide new insights into pathogenesis of CP, and allow CP to be better defined. METHODS: Expert physician-scientists from the United States, India, Europe and Japan reviewed medical and scientific literature and clinical experiences. Competing views and approaches were debated until a new consensus definition was reached. RESULTS: CP has been defined as 'a continuing inflammatory disease of the pancreas, characterized by irreversible morphological change, and typically causing pain and/or permanent loss of function'. Focusing on abnormal morphology makes early diagnosis challenging and excludes inflammation without fibrosis, atrophy, endocrine and exocrine dysfunction, pain syndromes and metaplasia. A new mechanistic definition is proposed--'Chronic pancreatitis is a pathologic fibro-inflammatory syndrome of the pancreas in individuals with genetic, environmental and/or other risk factors who develop persistent pathologic responses to parenchymal injury or stress.' In addition, "Common features of established and advanced CP include pancreatic atrophy, fibrosis, pain syndromes, duct distortion and strictures, calcifications, pancreatic exocrine dysfunction, pancreatic endocrine dysfunction and dysplasia." This definition recognizes the complex nature of CP, separates risk factors from disease activity markers and disease endpoints, and allows for a rational approach to early diagnosis, classification and prognosis. CONCLUSIONS: Initial agreement on a mechanistic definition of CP has been reached. This definition should be debated in rebuttals and endorsements, among experts and pancreatic societies until international consensus is reached.

Total pancreatectomy and islet autotransplantation in chronic pancreatitis: recommendations from PancreasFest.

DESCRIPTION: Total pancreatectomy with islet autotransplantation (TPIAT) is a surgical procedure used to treat severe complications of chronic pancreatitis or very high risk of pancreatic cancer while reducing the risk of severe diabetes mellitus. However, clear guidance on indications, contraindications, evaluation, timing, and follow-up are lacking. METHODS: A working group reviewed the medical, psychological, and surgical options and supporting literature related to TPIAT for a consensus meeting during PancreasFest. RESULTS: Five major areas requiring clinical evaluation and management were addressed: These included: 1) indications for TPIAT; 2) contraindications for TPIAT; 3) optimal timing of the procedure; 4) need for a multi-disciplinary team and the roles of the members; 5) life-long management issues following TPIAP including diabetes monitoring and nutrition evaluation. CONCLUSIONS: TPIAT is an effective method of managing the disabling complications of chronic pancreatitis and risk of pancreatic cancer in very high risk patients. Careful evaluation and long-term management of candidate patients by qualified multidisciplinary teams is required. Multiple recommendations for further research were also identified.

New developments in pancreatic cancer.

Pancreatic adenocarcinoma presents in an advanced stage and has a dismal prognosis. Extensive recent research efforts have provided us with greater insight into the etiology of pancreatic cancer and have also improved our means of prognostication. Molecular analysis demonstrated that specific pathways involved in pancreatic carcinogenesis are perhaps more valuable to study than single genetic aberrations. Previous risk factors, including family history, body mass index, and current cigarette smoking, were validated and novel risks, such as ABO blood group alleles, were identified. Similar to other illnesses, combinations of healthful habits, such as not smoking, adhering to a Mediterranean dietary pattern, and engaging in physical activity, may decrease pancreatic cancer risk. Finally, CA 19-9 levels, the presence of diabetes mellitus, and a six-gene signature provided critical information regarding survival that could help guide treatment of individuals diagnosed with pancreatic adenocarcinoma.

Pancreatic cancer patients who smoke and drink are diagnosed at younger ages.

BACKGROUND & AIMS: Cigarette smoking is an established risk factor for pancreatic cancer, but there is conflicting evidence regarding the effects of alcohol consumption. The effects of cigarettes and alcohol on age of sporadic pancreatic cancer diagnosis have not been examined; we evaluated the independent and synergistic effects of lifetime cigarette smoking and alcohol consumption on age at pancreatic cancer diagnosis in the United States. METHODS: We analyzed data on cigarette smoking and alcohol consumption from the IMPAC Services, Inc Cancer Information Resource File (CIRF), collected from June 1, 1993, to December 31, 2003, for 29,239 reported, histologically confirmed cases of pancreatic adenocarcinoma. We also analyzed data on cigarette smoking and alcohol consumption for 820 histologically confirmed cases of pancreatic adenocarcinoma from the University of Michigan Pancreatic Cancer Registry (UMPCR), collected from January 2004 to October 2007. RESULTS: Current cigarette smokers were diagnosed at significantly younger ages than never smokers, according to data from the CIRF and UMPCR (8.3 and 6.3 y, respectively); the UMPCR data indicated dose effects. Past and current alcohol consumption were associated with younger age at diagnosis in both databases. Current smokers who were current drinkers were diagnosed significantly earlier (CIRF, 10.2 y; UMPCR, 8.6 y) than abstainers. Past cigarette smoking was associated modestly with younger diagnosis age. CONCLUSIONS: Cigarette smoking and alcohol consumption were associated with younger age at pancreatic cancer presentation and have a combined effect on diagnosis age. Past cigarette smoking is less influential. Smoking cessation programs could help prevent pancreatic cancer.

Nutrition and Inflammatory Biomarkers in Chronic Pancreatitis Patients.

BACKGROUND: Chronic pancreatitis (CP) patients frequently experience malabsorption and maldigestion, leading to micronutrient and macronutrient deficiencies. Comorbid diabetes and lifestyle habits, such as alcohol consumption, may impact nutrition status. METHODS: We compared micronutrient antioxidant, bone metabolism, serum protein, and inflammatory marker levels in 301 CP patients and 266 controls with no known pancreatic disease. We analyzed serum prealbumin and retinol binding protein; vitamins A, D, E, and B12; osteocalcin; tumor necrosis factor-α; and C-reactive protein (CRP). We also evaluated biomarkers among subsets of patients, examining factors including time since diagnosis, body mass index, alcohol as primary etiology, diabetes mellitus, vitamin supplementation, and pancreatic enzyme replacement. RESULTS: After correcting for multiple comparisons, CP patients had significantly lower levels than controls of the following: vitamin A (40.9 vs 45.4 µg/dL) and vitamin E (α-tocopherol [8.7 vs 10.3 mg/L] and γ-tocopherol [1.8 vs 2.2 mg/L]), as well as osteocalcin (7.9 vs 10 ng/mL) and serum prealbumin (23 vs 27 mg/dL). Both patients and controls who took vitamin supplements had higher serum levels of vitamins than those not taking supplements. Compared with controls, in controlled analyses, CP patients had significantly lower levels of vitamins A, D, and E (both α-tocopherol and γ-tocopherol). CP patients also had significantly lower levels of osteocalcin, serum prealbumin, and retinol binding protein, and higher CRP. CONCLUSIONS: CP patients demonstrated lower levels of selected nutrition and bone metabolism biomarkers than controls. Diabetes and alcohol did not impact biomarkers. Vitamin supplements and pancreatic enzyme replacement therapy improved nutrition biomarkers in CP patients.

Multicenter approach to recurrent acute and chronic pancreatitis in the United States: the North American Pancreatitis Study 2 (NAPS2).

BACKGROUND: Recurrent acute pancreatitis (RAP) and chronic pancreatitis (CP) are complex syndromes associated with numerous etiologies, clinical variables and complications. We developed the North American Pancreatitis Study 2 (NAPS2) to be sufficiently powered to understand the complex environmental, metabolic and genetic mechanisms underlying RAP and CP. METHODS: Between August 2000 and September 2006, a consortium of 20 expert academic and private sites prospectively ascertained 1,000 human subjects with RAP or CP, plus 695 controls (spouse, family, friend or unrelated). Standardized questionnaires were completed by both the physicians and study subjects and blood was drawn for genomic DNA and biomarker studies. All data were double-entered into a database and systematically reviewed to minimize errors and include missing data. RESULTS: A total of 1,000 subjects (460 RAP, 540 CP) and 695 controls who completed consent forms and questionnaires and donated blood samples comprised the final dataset. Data were organized according to diagnosis, supporting documentation, etiological classification, clinical signs and symptoms (including pain patterns and duration, and quality of life), past medical history, family history, environmental exposures (including alcohol and tobacco use), medication use and therapeutic interventions. Upon achieving the target enrollment, data were organized and classified to facilitate future analysis. The approaches, rationale and datasets are described, along with final demographic results. CONCLUSION: The NAPS2 consortium has successfully completed a prospective ascertainment of 1,000 subjects with RAP and CP from the USA. These data will be useful in elucidating the environmental, metabolic and genetic conditions, and to investigate the complex interactions that underlie RAP and CP.

Pancreatitis in children and adolescents.

Several clinical and methodologic difficulties occur when diagnosing acute pancreatitis in the pediatric age group. Due to its uncommonness and heterogeneous symptoms, acute pancreatitis in children is often misdiagnosed, and prospective studies are lacking. Guidelines for classifying, diagnosing, and managing acute pancreatitis are frequently based on standards that are developed and validated in adult patients. Among the broad range of etiologies of pediatric acute pancreatitis in children, gallstones and biliary disease may play a greater role than previously believed. Although it is typically a benign disease in the pediatric population, complications such as pseudocysts may occur. When there are fatalities, they are usually attributed to systemic illness rather than the pancreatitis itself. Improvements in diagnostic and imaging methods and growing awareness cannot account for the recent increases in the observed incidence of pediatric acute pancreatitis.

Association between calcium sensing receptor gene polymorphisms and chronic pancreatitis in a US population: role of serine protease inhibitor Kazal 1type and alcohol.

AIM: To test the hypothesis that calcium sensing receptor (CASR) polymorphisms are associated with chronic pancreatitis (CP), and to determine whether serine protease inhibitor Kazal 1type (SPINK1) N34S or alcohol are necessary co-factors in its etiology. METHODS: Initially, 115 subjects with pancreatitis and 66 controls were evaluated, of whom 57 patients and 21 controls were predetermined to carry the high-risk SPINK1 N34S polymorphism. We sequenced CASR gene exons 2, 3, 4, 5 and 7, areas containing the majority of reported polymorphisms and novel mutations. Based on the initial results, we added 223 patients and 239 controls to analyze three common nonsynonymous single nucleotide polymorphisms (SNPs) in exon 7 (A986S, R990G, and Q1011E). RESULTS: The CASR exon 7 R990G polymorphism was significantly associated with CP (OR, 2.01; 95% CI, 1.12-3.59; P = 0.015). The association between CASR R990G and CP was stronger in subjects who reported moderate or heavy alcohol consumption (OR, 3.12; 95% CI, 1.14-9.13; P = 0.018). There was no association between the various CASR genotypes and SPINK1 N34S in pancreatitis. None of the novel CASR polymorphisms reported from Germany and India was detected. CONCLUSION: Our United States-based study confirmed an association of CASR and CP and for the first time demonstrated that CASR R990G is a significant risk factor for CP. We also conclude that the risk of CP with CASR R990G is increased in subjects with moderate to heavy alcohol consumption.

The Inflammatory Bowel Disease Specialty Medical Home: A New Model of Patient-centered Care.

New models of health care have emerged over the past decade. Accountable care organizations and patient-centered medical homes are designed to improve the patient experience, enhance health care quality, and decrease cost. These models have been developed in the primary care domain and have yet to be tested in specialty care. Certain chronic diseases require principal care by a specialist or health care team. The specialty medical home would provide patient-centered care for specific populations of patients whose health care derives from a single chronic disease. This article defines the parameters for a specialty medical home and provides a specific payer-provider experience for the comprehensive care of an inflammatory bowel disease population.

Androgenic progestins in oral contraceptives and the risk of epithelial ovarian cancer.

OBJECTIVE: Oral contraceptives (OCs) have been consistently linked to reduced risk of ovarian cancer. Oral contraceptive formulations display varying degrees of androgenicity. Data linking androgens to ovarian cancer suggest that OC androgenicity may impact efficacy in preventing ovarian cancer. The authors investigated whether OC efficacy might differ according to androgenicity by using data from a large, population-based, case-control study (the Steroid Hormones and Reproductions [SHARE] Study). METHODS: Detailed data on OC formulation was obtained by an in-person interview for 568 cases and 1,026 controls. Multivariable logistic regression was used to assess the association of OC androgenicity with ovarian cancer while controlling for the known potential confounders of age, parity, family history of ovarian cancer, and tubal ligation. RESULTS: Androgenic and nonandrogenic OCs conferred a similar and significant reduction in ovarian cancer risk (odds ratio 0.52, 95% confidence interval 0.35-0.76 and odds ratio 0.59, 95% confidence interval 0.45-0.78, respectively). No differences in duration of use, age at first use, and time since last use were found between androgenic and nonandrogenic formulations. CONCLUSION: In general, the androgenicity of an OC does not alter chemopreventive efficacy. LEVEL OF EVIDENCE: II-2.

Epidemiologic and Mechanistic Associations Between Smoking and Pancreatitis.

OPINION STATEMENT: Alcohol has long been associated with pancreatitis. Although first described more than three decades ago, smoking has been widely accepted as an important risk factor for all forms of pancreatitis only in the past few years. Empiric data has confirmed smoking as an independent and dose-dependent risk for both acute and chronic pancreatitis. Smoking also increases the risk of recurrences and progression of established chronic pancreatitis. The effects of smoking are enhanced in the presence of alcohol consumption. Indirect evidence suggests that smoking cessation may be beneficial in preventing disease progression. Smoking cessation can therefore be an important strategy for primary as well as secondary prevention of pancreatitis. Therefore, in addition to alcohol, physicians should routinely counsel patients for the benefits of smoking cessation. The mechanisms through which cigarette smoke triggers pathological cellular events, resulting in pancreatitis, are unresolved. Although cigarette smoke contains greater than 4000 compounds, principally nicotine and the tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) have been broadly studied with regard to pancreatic diseases. Both nicotine and NNK have been shown to induce morphological changes in the pancreas consistent with those seen in pancreatitis. Furthermore, nicotine affects pancreatic secretion and NNK induces premature zymogen activation, two well-known features of pancreatitis. These cigarette toxins may mediate both pro- and anti-inflammatory pathways and can induce changes in pancreatic acinar cell function at the level of transcription, leading to conditions such as thiamin deficiency and mitochondrial dysfunction. Such circumstances could leave the pancreas prone to the development of pancreatitis. This review summarizes relevant research findings and focuses on the epidemiologic links between smoking and pancreatitis, and the cellular pathways that may be significant in induction and evolution of smoking-related pancreatitis.

The inflammatory bowel disease live interinstitutional and interdisciplinary videoconference education (IBD LIVE) series.

BACKGROUND: Managing patients with inflammatory bowel disease requires multidisciplinary coordination. Technological advances have enhanced access to care for patients and improved physician interactions. The primary aim of our project was to convene diverse institutions and specialties through a multisite virtual conferencing platform to discuss complex patient management. METHODS: The case conference is designed to include multiple institutions to exchange ideas, review evidence-based data, and provide input on the management of patients with Crohn's disease and ulcerative colitis. Technology is supplied and coordinated by an information technology specialist and Chorus Call, Inc., an international teleconferencing service provider. The Inflammatory Bowel Disease Live Interinstitutional Interdisciplinary Videoconference Education (IBD LIVE) initiative is accredited by the University of Pittsburgh Medical Center (UPMC) Center for Continuing Education in the Health Sciences for 1 AMA PRA Category 1 Credit per weekly session. RESULTS: IBD LIVE began in 2009 comprising only adult gastroenterology and pediatric gastroenterology from UPMC Presbyterian and Children's Hospitals. Participation steadily increased from 5 sites in 2010 to 11 sites in 2014. Maximum attendance for a single conference was 73 participants with a median of 48. The Continuing Medical Education scores (1 = worst to 5 = best) have a high median overall score (4.6, range 3.2-5.0) with positive responses with regard to the degree to which the conference changed practice. CONCLUSIONS: IBD LIVE has been successful and continues to grow. Implementation of the Crohn's and Colitis Foundation of America Virtual Preceptor Program using the IBD LIVE platform will provide expanded national physician access to this professional education activity.
