Abstract
Formidable health problems are often best addressed by teams of scientists with varied expertise. This diversity among team members and complexities in managing teams can lead to challenges in designing, funding, conducting, and reporting research. Team science difficulties can be addressed by sophisticated planning, frequent reassessment and realignment of team strategies with goals, and consistent transparent communication. This article addresses specific strategies to build and sustain research teams, manage team meetings, strategically develop publications and grants, thrive in the midst of disciplinary and individual team member differences, embrace new ideas and change to maintain creativity, and build future team scientists and projects. The potential value in team science justifies the effort required to build and maintain efficient and effective research teams.

Abstract
OBJECTIVE Attempts to categorize distinct functional gastrointestinal disorders based on reported symptoms continue but symptoms frequently overlap. The study objective was to use latent class analysis (LCA) which accommodates both continuous and discrete manifest variables to determine mutually exclusive subgroup assignments of a population-based sample using gastrointestinal symptom and patient data. MATERIALS AND METHODS A validated bowel disease questionnaire and somatic symptom questionnaire were mailed to an age and gender stratified randomly selected community sample. Responses to the symptom questions were dichotomized as frequent vs. infrequent based on Rome IV criteria. A LCA model was developed using a calibration subset and the results applied to the validation subset. RESULTS There were 3831 total respondents (48%) with 3425 having complete data. The LCA algorithm was run for each of 10 (random) splits of the dataset and 2-6 latent classes were specified. Using the values of Akaike's Information Criterion coefficient c to determine fit of the data, 4 latent classes yielded better values resulting in four subgroups: 'asymptomatic,' 'upper' abdominal symptoms, 'lower' abdominal symptoms, and 'mixed' (upper and lower abdomen). CONCLUSIONS Latent class analysis identified 4 groups based on symptoms. This approach resulted in differentiation by anatomical region rather than the Rome IV classification of symptoms.

Abstract
BACKGROUND & AIMS Tricyclic antidepressants are effective in reducing symptoms of functional dyspepsia (FD). We performed a post hoc analysis of data from a previous randomized clinical trial to determine whether the benefits of an antidepressant on gastrointestinal symptoms in patients with FD were mediated by improving sleep or reducing anxiety. We explored the relationships between psychological measures, quality of sleep, and relief of symptoms. METHODS We analyzed data from a multicenter, double-blind trial that evaluated the efficacy of antidepressants on symptoms of FD, from October 2006 through October 2012. Patients (n = 292) were randomly assigned to groups given 50 mg amitriptyline, 10 mg escitalopram, or placebo for 12 weeks. During the study, participants completed the following validated psychological questionnaires: Symptom Check List 90, Symptom Somatic Checklist, Hospital Anxiety Depression Scale, Profile of Mood States, State Trait Anxiety Inventory, and Pittsburgh Sleep Quality Index at baseline and 12 weeks following treatment. RESULTS Baseline scores for the psychological and sleep measures were similar among groups; after 12 weeks there were no significant differences in scores among groups. Baseline mean global Pittsburgh Sleep Quality Index scores indicated poor sleep quality in all groups at baseline and after 12 weeks. Overall, antidepressants affected sleep duration scores: patients given amitriptyline had lower (better) scores than patients given placebo or escitalopram (P = .019). In all groups, responders had decreased anxiety and improvements in some sleep components. CONCLUSIONS In a post hoc analysis of data from a clinical trial that evaluated the effects of antidepressants in patients with FD, amitriptyline was found to reduce symptoms of FD, but its mechanism is unlikely to involve reductions in psychological distress. The drug may modestly improve sleep. Clinicaltrials.gov no: NCT00248651.

Abstract
BACKGROUND Functional dyspepsia (FD) is a highly prevalent functional bowel disorder. The effects of antidepressant therapy (ADTx) on gastric sensorimotor function in FD patients are poorly understood. AIMS Determine whether FD and subtypes with abnormalities in gastric function respond differently to ADTx compared to those with normal physiology. METHODS This multicenter, prospective trial randomized FD patients to 12 weeks of amitriptyline (AMI; 50 mg), escitalopram (ESC; 10 mg), or matching placebo. Demographics, symptoms, psychological distress, gastric emptying, and satiation were measured. Gastric accommodation (GA) using single-photon emission computed tomography imaging was performed in a subset of patients. An intent to treat analysis included all randomized subjects. The effect of treatment on gastric emptying was assessed using ANCOVA. A post hoc appraisal of the data was performed categorizing patients according to the Rome III subgrouping (PDS and EPS). RESULTS In total, 292 subjects were randomized; mean age=44 yrs. 21% had delayed gastric emptying. Neither antidepressant altered gastric emptying, even in those with baseline delayed gastric emptying. GA increased with ADTx (P=0.02). Neither antidepressant affected the maximal-tolerated volume (MTV) of the nutrient drink test although aggregate symptom scores improved compared to placebo (P=0.04). Patients with the combined EPS-PDS subtype (48%) had a lower MTV on the nutrient drink test compared to the EPS group at baseline (P=0.02). Postprandial bloating improved with both AMI (P=0.03) and ESC (P=0.02). CONCLUSIONS Amitriptyline (50 mg) improves FD symptoms but does not delay gastric emptying, even in patients with baseline delayed gastric emptying. GA improved with low-dose ADTx; the precise mechanism of action is unknown warranting further study.

Abstract
Junior faculty follow a research path replete with challenges as they strive to create knowledge in their area of interest while balancing new responsibilities. Unlike graduate school, where students focus inward on personal development, junior faculty must add responsibilities in ways that hold them accountable as members of a university. This special article deals with three themes of interest to new junior faulty launching research programs: personal development, collaboration and team development within university settings, and funding advice. Strategies in these areas provide guidance on navigating early careers and finding success in the academic setting.

Abstract
OBJECTIVE Patients with constipation account for 3.1 million US physician visits a year, but care costs for patients with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC) compared to the general public have received little study. The study aim was to describe healthcare utilization and compare medical costs for patients with IBS-C or CIC vs matched controls from a community-based sample. METHODS A nested case-control sample (IBS-C and CIC cases) and matched controls (1:2) for each case group were selected from Olmsted County, MN, individuals responding to a community-based survey of gastrointestinal symptoms (2008) who received healthcare from a participating Rochester Epidemiology Project (REP) provider. Using REP healthcare utilization data, unadjusted and adjusted standardized costs were compared for the 2- and 10-year periods prior to the survey for 115 IBS-C patients and 230 controls and 365 CIC patients and 730 controls. Two time periods were chosen as these conditions are episodic, but long-term. RESULTS Outpatient costs for IBS-C ($6,800) and CIC ($6,284) patients over a 2-year period prior to the survey were significantly higher than controls ($4,242 and $5,254, respectively) after adjusting for co-morbidities, age, and sex. IBS-C outpatient costs ($25,448) and emergency room costs ($6,892) were significantly higher than controls ($21,024 and $3,962, respectively) for the 10-year period prior. Unadjusted data analyses of cases compared to controls demonstrated significantly higher imaging costs for IBS-C cases and procedure costs for CIC cases over the 10-year period. LIMITATIONS Data were collected from a random community sample primarily receiving care from a limited number of providers in that area. CONCLUSIONS Patients with IBS-C and CIC had significantly higher outpatient costs for the 2-year period compared with controls. IBS-C patients also had higher ER costs than the general population.

Abstract
BACKGROUND Early life events have been found to be associated with irritable bowel syndrome (IBS) suggesting a role in development of functional disorders. The study aim was to identify potential perinatal risk factors for adult IBS. METHODS Utilizing a population-based nested case-control design, cases who met modified Rome III criteria for IBS and age- and-gender matched controls were identified using responses from prior mailed surveys to a random sample of Olmsted County residents. Medical records of eligible respondents were reviewed for perinatal events of interest. The association of early life events with subsequent case status was assessed using conditional logistic regression. KEY RESULTS Of 3 417 respondents, 513 were born in Olmsted County and 108 met criteria for IBS. Due to missing records, 89 pairs were included in the final analyses. Logistic regression revealed only birth weight as a predictor of IBS. Lower birth weight increased the odds for IBS (OR = 1.54 [95% CI = (1.12, 2.08), p = 0.008]). Median birth weight was 3.35 kg (range: 1.96-5.24) and 3.57 kg (range: 2.18-4.59) for cases and controls, respectively. Maternal age, delivery method, and antibiotic exposure were not associated with IBS status but this study was only powered to detect large odds ratios. CONCLUSIONS AND INFERENCES Lower birth weight was observed as a risk factor for IBS. It is not clear if in utero developmental delays directly lead to IBS or if low birth weight is a prospective marker for subsequent early life problems leading to IBS.

Abstract
OBJECTIVE To assess the usefulness of a community-based mailed survey to identify participants with functional dyspepsia (FD) for a clinical trial. MATERIAL AND METHODS In 2008, a valid self-report questionnaire of gastrointestinal symptoms required for diagnosis of FD was mailed to randomly selected cohorts of Olmsted County, Minnesota, residents. From survey responses (54%), FD cases and controls were identified. Phone calls were completed in 2010 and 2011 to 54% of respondents offering participation to those meeting criteria. RESULTS Of 937 people identified from the survey, 189 cases and 265 controls were contacted by phone using four questions similar to the written survey resulting in a moderate level of agreement (Kappa 0.43, 95% CI: 0.35- 0.51; p = 0.11). The proportion reporting FD symptoms by survey was 42%, while the proportion by phone was 38%. Comparing classification of cases and controls, 118 (62%) survey cases had dyspepsia symptoms on phone screening while 53 (20%) of the survey controls reported FD symptoms. Of 171 who had symptoms, 60 (35%) declined, 33 (19%) were over study age limit, 24 (14%) had inadequate symptom levels and 36 (21%) had comorbidities. Of survey respondents contacted, six (3%) people were enrolled with two screen fails resulting in four (1%) randomized. CONCLUSION Agreement between survey and phone questions was modest. Classifications between case and control changed. People eligible and willing to participate were a fraction of people reporting symptoms. People participating in clinical trials do not broadly represent those in the population.

Abstract
BACKGROUND & AIMS Antidepressants are frequently prescribed to treat functional dyspepsia (FD), a common disorder characterized by upper abdominal symptoms, including discomfort or postprandial fullness. However, there is little evidence of the efficacy of these drugs in patients with FD. We performed a randomized, double-blind, placebo-controlled trial to evaluate the effects of antidepressant therapy on symptoms, gastric emptying (GE), and meal-induced satiety in patients with FD. METHODS We performed a study at 8 North American sites of patients who met the Rome II criteria for FD and did not have depression or use antidepressants. Patients (n = 292; 44 ± 15 years old, 75% were female, 70% with dysmotility-like FD, and 30% with ulcer-like FD) were randomly assigned to groups given placebo, 50 mg amitriptyline, or 10 mg escitalopram for 10 weeks. The primary end point was adequate relief of FD symptoms for ≥5 weeks of the last 10 weeks (of 12). Secondary end points included GE time, maximum tolerated volume in Nutrient Drink Test, and FD-related quality of life. RESULTS An adequate relief response was reported by 39 subjects given placebo (40%), 51 given amitriptyline (53%), and 37 given escitalopram (38%) (P = .05, after treatment, adjusted for baseline balancing factors including all subjects). Subjects with ulcer-like FD given amitriptyline were >3-fold more likely to report adequate relief than those given placebo (odds ratio = 3.1; 95% confidence interval: 1.1-9.0). Neither amitriptyline nor escitalopram appeared to affect GE or meal-induced satiety after the 10-week period in any group. Subjects with delayed GE were less likely to report adequate relief than subjects with normal GE (odds ratio = 0.4; 95% confidence interval: 0.2-0.8). Both antidepressants improved overall quality of life. CONCLUSIONS Amitriptyline, but not escitalopram, appears to benefit some patients with FD, particularly those with ulcer-like (painful) FD. Patients with delayed GE do not respond to these drugs. ClinicalTrials.gov ID: NCT00248651.

Abstract
BACKGROUND There is symptom overlap between gastro-esophageal reflux disease (GERD) and functional dyspepsia (FD). We aimed to test the hypothesis that FD cases are now more likely mislabeled as GERD. METHODS In subjects from Olmsted County, MN seen at Mayo Clinic: (i) Investigation of GERD and FD diagnosis rates between 1985 and 2009. (ii) Assessment of survey-based upper gastrointestinal symptoms between 1988 and 2009. (iii) Analysis of patients reporting GERD and/or FD symptoms and subsequently receiving a consistent diagnosis of GERD and/or FD during a medical encounter. (iv) Assess the association between PPI use and GERD and/or FD symptoms and between actual diagnoses received. KEY RESULTS (i) Yearly GERD diagnosis rates rose between 1985 and 2009 (325-1866 per 100 000). FD diagnosis rates rose from 45 in 1985, to 964 in 1999 but decreased to 452 per 100 000 in 2009. (ii) Reported GERD symptoms did not significantly change between three survey waves in the years 1988-2009 (p = 0.052), whereas FD symptoms slightly increased (p = 0.01). (iii) 62.9% of subjects reporting GERD symptoms received a GERD diagnosis, however only 12.5% of subjects reporting FD symptoms received a FD diagnosis. (iv) PPI use was associated with documented GERD diagnosis (p < 0.001), however there was no significant association between GERD symptoms and PPI use (p = 0.078). CONCLUSIONS & INFERENCES We have found evidence supporting a systematic bias away from diagnosing FD, favoring a GERD diagnosis.

Abstract
The current health-care environment is demanding evidence-based medicine that relies on clinical trials as the basis for decisions. Clinician investigators are more often finding that they are personally responsible for coordinating large, multisite trials. We present strategies for successful implementation and management of multisite clinical trials and knowledge gained through an international, multisite randomized clinical trial. Topics include team composition, regulatory requirements, study organization and governance, communication strategies, recruitment and retention efforts, budget, technology transfer, and publication.

Abstract
BACKGROUND Functional dyspepsia (FD) is a common problem affecting up to 10-25% of individuals. FD accounts for significant health care costs and affects quality of life but has no definitive treatment. OBJECTIVES The Functional Dyspepsia Treatment Trial (FDTT) aims to test whether treatment with an antidepressant (amitriptyline or escitalopram) leads to improvement of symptoms in patients with moderate to severe FD. DESIGN The FDTT is an international multicenter, parallel group, randomized, double-blind, placebo-controlled trial to evaluate whether 12 weeks of treatment with escitalopram or amitriptyline improves FD symptoms compared to treatment with placebo. Secondly, it is hypothesized that acceleration of solid gastric emptying, reduction of postprandial satiation, and enhanced gastric volume change with a meal will be significant positive predictors of short- and long-term outcomes for those on antidepressants vs. placebo. The third aim is to examine whether polymorphisms of GNβ3 and serotonin reuptake transporter influence treatment outcomes in FD patients receiving a tricyclic antidepressant, selective serotonin reuptake inhibitor therapy, or placebo. METHODS The FDTT enrollment began in 2006 and is scheduled to randomize 400 patients by the end of 2012 to receive an antidepressant or placebo for 12 weeks, with a 6-month post-treatment follow-up. The study incorporates multiple validated questionnaires, physiological testing, and specific genetic evaluations. The protocol was approved by participating centers' Institutional Review Boards and an independent Data Safety Monitoring Board was established for monitoring to ensure patient safety and a single interim review of the data in December 2010 (ClinicalTrials.gov number NCT00248651).

Abstract
BACKGROUND The psychological symptoms associated with binge eating disorder (BED) have been well documented. However, the physical symptoms associated with BED have not been explored. Gastrointestinal (GI) symptoms such as heartburn and diarrhea are more prevalent in obese adults, but the associations remain unexplained. Patients with bulimia have increased gastric capacity. The objective of the study was to examine if the severity of binge eating episodes would be associated with upper and lower GI symptoms. METHODS Population-based survey of community residents through a mailed questionnaire measuring GI symptoms, frequency of binge eating episodes and physical activity level. The association of GI symptoms with frequency of binge eating episodes was assessed using logistic regression models adjusting for age, gender, body mass index (BMI) and physical activity level. RESULTS In 4096 subjects, BED was present in 6.1%. After adjusting for BMI, age, gender, race, diabetes mellitus, socioeconomic status and physical activity level, BED was independently associated with the following upper GI symptoms: acid regurgitation (P<0.001), heartburn (P<0.001), dysphagia (P<0.001), bloating (P<0.001) and upper abdominal pain (P<0.001). BED was also associated with the following lower GI symptoms: diarrhea (P<0.001), urgency (P<0.001), constipation (P<0.01) and feeling of anal blockage (P=0.001). CONCLUSION BED appears to be associated with the experience of both upper and lower GI symptoms in the general population, independent of the level of obesity. The relationship between increased GI symptoms and physiological responses to increased volume and calorie loads, nutritional selections and rapidity of food ingestion in individuals with BED deserves further study.

Abstract
In tertiary referral patients, there is association between altered sleep patterns, functional bowel disorders and altered gut motor function. Body mass index (BMI) is also associated with gastrointestinal (GI) symptoms including diarrhoea, and with sleep disturbances. Our hypothesis is that sleep disturbances are associated with GI symptoms, and this is not explained by BMI. A 48-item-validated questionnaire was mailed to 6939 community participants in Olmsted County, MN. The survey included GI symptoms, sleep disturbance, daily lifestyle and quality of life (QOL). Independent contributions of sleep disturbance to individual symptoms were assessed using logistic regression adjusting for age, gender, lifestyle and mental health status. The association of an overall sleep score with an overall symptom score was examined and the ability of both scores to predict SF-12 physical and mental functioning scores assessed in multiple linear regression models. Among 3228 respondents, 874 (27%) reported trouble staying asleep. There was a significant correlation of overall sleep scores with overall GI symptom scores (partial r = 0.28, P < 0.001). Waking up once nightly at least four times a month was significantly associated with pain, nausea, dysphagia, diarrhoea, loose stools, urgency and a feeling of anal blockage. Trouble falling asleep was significantly associated with rectal urgency. Associations were independent of gender, age, lifestyle factors and BMI. Overall, sleep scores and GI symptom scores were both significant independent predictors of impaired QOL. In the community, reporting poor sleep is associated with upper and lower GI symptoms, but this is independent of BMI.

Abstract
OBJECTIVE To measure a 1-day point prevalence of alcohol dependence among hospitalized patients and to assess practices of detection, evaluation, and diagnosis of alcohol problems. PATIENTS AND METHODS On April 27, 1994, a total of 795 adult inpatients at 2 midwestern teaching hospitals were asked to complete a survey that included the Self-administered Alcoholism Screening Test (SAAST). The records of SAAST-positive patients were reviewed to determine the numbers of patients receiving laboratory screening for alcoholism, addiction consultative services, and a discharge diagnosis of alcoholism. RESULTS The survey response rate was 84% (667/795). Of the 569 patients who provided SAAST information, 42 (7.4%) had a positive SAAST score and thus were identified as alcohol dependent. Thirteen (31%) of the 42 alcoholic patients received addiction or psychiatric consultative services during their hospitalization. Serum gamma-glutamyltransferase was measured in 4 (11%) of the 38 actively drinking alcoholic patients. Three (7%) of 42 alcoholic patients received a discharge diagnosis of alcohol abuse or dependence. CONCLUSIONS The alcoholism prevalence rate was lower than those observed in several other US hospitals. Laboratory testing may be underutilized in identifying hospitalized patients who may be addicted to alcohol. Physician use of consultative services and diagnosis of alcohol dependence had not improved from similar observations more than 20 years earlier. These findings may indicate persistent problems in physician detection, assessment, and diagnosis of alcoholism.

Abstract
This prospective study assessed the relationship between current tobacco use and history of an alcohol problem to health status in hospitalized patients. Factors associated with current tobacco use and history of an alcohol problem were also evaluated. Data were collected using a self-administered survey distributed by nursing staff to adult inpatients registered on April 27, 1994 at the Mayo Clinic, Rochester, Minnesota affiliated hospitals. Respondents (N = 589, 45% female) were classified into 4 subgroups based on current tobacco use status and history of an alcohol problem: (a) current tobacco use only (n = 94, 16%); (b) history of an alcohol problem only (n = 30, 5%); (c) both (n = 27, 5%); or (d) neither (n = 438, 74%). Patients with both current tobacco use and an alcohol problem history reported markedly lower scores on health status measures of general and mental health compared to the other three subgroups. Moreover, current tobacco use and history of an alcohol problem were each associated with increased psychological distress. Current tobacco use was predictive of a history of an alcohol problem and vice versa.

Abstract
Concepts such as symptoms present specific representational challenges in the EMR. This is because concepts without clear boundaries and external referents such as physical objects can only be examined against other terminology-based concept representation systems. The truth and falsity of such concept representation is therefore relative to the terminology-based systems. Using the concept of acute postoperative pain as an example, we examined three terminology based approaches to representing the concept. Widely varying coverage across existing clinical terminologies was evident, although the common clinical approach to reporting attributes of symptoms provided a useful organizational structure and should be examined in relation to developing terminology and information models.
