Abstract
Background Improvement in bowel urgency (BU) was associated with better clinical outcomes in phase 3 LUCENT-1 (induction) and LUCENT-2 (maintenance) studies in moderately-to-severely active ulcerative colitis (UC). We assessed association of BU with quality-of-life (QoL) outcomes. Methods LUCENT-1: 1162 patients randomized 3:1 to intravenous mirikizumab 300 mg or placebo every 4 weeks (Q4W) for 12 weeks. LUCENT-2: 544 mirikizumab induction responders re-randomized 2:1 to subcutaneous mirikizumab 200 mg or placebo Q4W through Week (W) 40 (W52 of continuous treatment). Patients reported BU severity in the past 24 hours using a validated Urgency Numeric Rating Scale (NRS). In patients with baseline Urgency NRS ≥3, the association between BU Clinically Meaningful Improvement (CMI; ≥3-point decrease) and remission (score 0 or 1) with patient-reported outcomes was assessed at W12 and W52. Results A significantly greater proportion of patients with versus without BU Remission achieved IBDQ remission (W12: 87.3% vs 42.7%, P < .0001; W52: 91.4% vs 45.5%, p < .0001). Similarly, BU Remission was associated with more patients achieving CMI in SF-36 Physical Component Summary (W12: 69.0% vs 44.4%, P < .0001; W52: 77.5% vs 42.1%, P < .0001) and Mental Component Summary (W12: 53.5% vs 41.0%, P = .0019; W52: 62.0% vs 38.3%, P < .0001) scores. At W12 and W52, patients with BU CMI or Remission showed significant improvements in EQ-5D-5L and Work Productivity and Activity Impairment:UC scores. Significant improvements were also seen in fatigue, abdominal pain, and nocturnal stool. Conclusions In patients with moderately-to-severely active UC, improvement in BU was associated with improved QoL in phase 3 LUCENT-1 and LUCENT-2 studies. Clinical Studies LUCENT-1: NCT03518086; LUCENT-2: NCT03524092.

Abstract
Gastroesophageal reflux disease (GERD) is common in patients who have undergone lung transplantation and is associated with poorer outcomes, but guidelines are lacking to direct management strategies in this population. We assessed the diagnostic yield of impedance metrics compared to pH-metry alone for detecting GERD among lung transplant recipients and evaluated their association with clinical outcomes. We performed a retrospective cohort study of consecutive patients who underwent lung transplantation. Demographic data, acid exposure time (AET), number of reflux episodes, mean nocturnal baseline impedance (MNBI), post-reflux swallowing-induced peristaltic wave index (PSPWI), and clinical outcomes including mortality were collected. The relationship between GERD metrics and clinical outcomes was assessed using Wilcoxon signed-rank test and Fisher's exact test as appropriate. Of the 76 patients studied, 29 (38%) had GERD based on abnormal AET after lung transplantation. One (1.3%) patient had GERD based on elevated number of reflux episodes and abnormal distal MNBI detected GERD in 19 (26%) patients, resulting in 62% sensitivity and 94% specificity. Two (2.6%) patients had normal PSPWI. Patients with low distal MNBI had significantly decreased forced expiratory volume in 1 second (FEV1) at 3-year posttransplant compared to those without low distal MNBI (P = 0.03). Three-year survival was significantly worse among patients with elevated AET (66.7% vs. 89.1%, P = 0.03) but not with low distal MNBI (68.4% vs. 84.3%, P = 0.18). Abnormal AET is more sensitive for detecting GERD than other reflux metrics studied and is associated with survival, suggesting pH-metry alone may be sufficient to guide GERD management after lung transplant.

Abstract
Importance The Colonoscopy Versus Fecal Immunochemical Test in Reducing Mortality From Colorectal Cancer (CONFIRM) randomized clinical trial sought to recruit 50 000 adults into a study comparing colorectal cancer (CRC) mortality outcomes after randomization to either an annual fecal immunochemical test (FIT) or colonoscopy. Objective To (1) describe study participant characteristics and (2) examine who declined participation because of a preference for colonoscopy or stool testing (ie, fecal occult blood test [FOBT]/FIT) and assess that preference's association with geographic and temporal factors. Design, Setting, and Participants This cross-sectional study within CONFIRM, which completed enrollment through 46 Department of Veterans Affairs medical centers between May 22, 2012, and December 1, 2017, with follow-up planned through 2028, comprised veterans aged 50 to 75 years with an average CRC risk and due for screening. Data were analyzed between March 7 and December 5, 2022. Exposure Case report forms were used to capture enrolled participant data and reasons for declining participation among otherwise eligible individuals. Main Outcomes and Measures Descriptive statistics were used to characterize the cohort overall and by intervention. Among individuals declining participation, logistic regression was used to compare preference for FOBT/FIT or colonoscopy by recruitment region and year. Results A total of 50 126 participants were recruited (mean [SD] age, 59.1 [6.9] years; 46 618 [93.0%] male and 3508 [7.0%] female). The cohort was racially and ethnically diverse, with 748 (1.5%) identifying as Asian, 12 021 (24.0%) as Black, 415 (0.8%) as Native American or Alaska Native, 34 629 (69.1%) as White, and 1877 (3.7%) as other race, including multiracial; and 5734 (11.4%) as having Hispanic ethnicity. Of the 11 109 eligible individuals who declined participation (18.0%), 4824 (43.4%) declined due to a stated preference for a specific screening test, with FOBT/FIT being the most preferred method (2820 [58.5%]) vs colonoscopy (1958 [40.6%]; P < .001) or other screening tests (46 [1.0%] P < .001). Preference for FOBT/FIT was strongest in the West (963 of 1472 [65.4%]) and modest elsewhere, ranging from 199 of 371 (53.6%) in the Northeast to 884 of 1543 (57.3%) in the Midwest (P = .001). Adjusting for region, the preference for FOBT/FIT increased by 19% per recruitment year (odds ratio, 1.19; 95% CI, 1.14-1.25). Conclusions and Relevance In this cross-sectional analysis of veterans choosing nonenrollment in the CONFIRM study, those who declined participation more often preferred FOBT or FIT over colonoscopy. This preference increased over time and was strongest in the western US and may provide insight into trends in CRC screening preferences.

Abstract
OBJECTIVES To evaluate healthcare costs, resource utilization, associated costs, and lost productivity for colorectal cancer (CRC) screening in an average-risk population. METHODS This retrospective cohort study identified average-risk individuals (50-75 years) with claims in the Optum Research Database for CRC screening test between 1 January 2014 to 31 December 2018. Index date was defined as the first date of a claim for colonoscopy, fecal immunochemical test (FIT), guaiac-based fecal occult blood test (FOBT) or multi-target stool DNA test (mt-sDNA). Screening costs were evaluated with descriptive statistics and multivariable analyses, adjusting for patient characteristics and index screening costs. RESULTS In total, 903,831 individuals were identified by test groups: mt-sDNA (n = 29,614), FIT (n = 254,002), guaiac-based FOBT (n = 112,757) and colonoscopy (n = 507,458). Adjusted costs for index screening were, colonoscopy ($3,029), mt-sDNA ($752), FIT ($45), and (FOBT ($153). Adjusted costs across the six months following the index screening were $146 for colonoscopy, $329 for mt-sDNA, $306 for FIT, and $412 for FOBT. Colonoscopy had the highest costs for lost productivity. CONCLUSIONS Screening colonoscopy had the highest productivity loss and healthcare costs up-front, suggesting potential cost benefits for noninvasive screening modalities. The more frequent screening interval required for FIT and FOBT resulted in a higher yearly cost than colonoscopy or mt-sDNA.

Abstract
BACKGROUND To assess patient and primary care provider (PCP) factors associated with adherence to American Cancer Society (ACS) and United States Preventive Services Task Force (USPSTF) guidelines for average risk colorectal cancer (CRC) screening. METHODS Retrospective case-control study of medical and pharmacy claims from the Optum Research Database from 01/01/2014 - 12/31/2018. Enrollee sample was adults aged 50 - 75 years with ≥ 24 months continuous health plan enrollment. Provider sample was PCPs listed on the claims of average-risk patients in the enrollee sample. Enrollee-level screening opportunities were based on their exposure to the healthcare system during the baseline year. Screening adherence, calculated at the PCP level, was the percent of average-risk patients up to date with screening recommendations each year. Logistic regression modelling was used to examine the association between receipt of screening and enrollee and PCP characteristics. An ordinary least squares model was used to determine the association between screening adherence among the PCP's panel of patients and patient characteristics. RESULTS Among patients with a PCP, adherence to ACS and USPSTF screening guidelines ranged from 69 to 80% depending on PCP specialty and type. The greatest enrollee-level predictors for CRC screening were having a primary/preventive care visit (OR = 4.47, p < 0.001) and a main PCP (OR = 2.69, p < 0.001). CONCLUSIONS Increased access to preventive/primary care visits could improve CRC screening rates; however, interventions not dependent on healthcare system contact, such as home-based screening, may circumvent the dependence on primary care visits to complete CRC screening.

Abstract
BACKGROUND Obtaining comprehensive family health history (FHH) to inform colorectal cancer (CRC) risk management in primary care settings is challenging. OBJECTIVE To examine the effectiveness of a patient-facing FHH platform to identify and manage patients at increased CRC risk. DESIGN Two-site, two-arm, cluster-randomized, implementation-effectiveness trial with primary care providers (PCPs) randomized to immediate intervention versus wait-list control. PARTICIPANTS PCPs treating patients at least one half-day per week; patients aged 40-64 with no medical conditions that increased CRC risk. INTERVENTIONS Immediate-arm patients entered their FHH into a web-based platform that provided risk assessment and guideline-driven decision support; wait-list control patients did so 12 months later. MAIN MEASURES McNemar's test examined differences between the platform and electronic medical record (EMR) in rates of increased risk documentation. General estimating equations using logistic regression models compared arms in risk-concordant provider actions and patient screening test completion. Referral for genetic consultation was analyzed descriptively. KEY RESULTS Seventeen PCPs were randomized to each arm. Patients (n = 252 immediate, n = 253 control) averaged 51.4 (SD = 7.2) years, with 83% assigned male at birth, 58% White persons, and 33% Black persons. The percentage of patients identified as increased risk for CRC was greater with the platform (9.9%) versus EMR (5.2%), difference = 4.8% (95% CI: 2.6%, 6.9%), p < .0001. There was no difference in PCP risk-concordant action [odds ratio (OR) = 0.7, 95% CI (0.4, 1.2; p = 0.16)]. Among 177 patients with a risk-concordant screening test ordered, there was no difference in test completion, OR = 0.8 [0.5,1.3]; p = 0.36. Of 50 patients identified by the platform as increased risk, 78.6% immediate and 68.2% control patients received a recommendation for genetic consultation, of which only one in each arm had a referral placed. CONCLUSIONS FHH tools could accurately assess and document the clinical needs of patients at increased risk for CRC. Barriers to acting on those recommendations warrant further exploration.

Abstract
BACKGROUND Pancreatic cancer has a poor 5-year survival and carries significant morbidity. Pain is a commonly studied symptom in pancreatic cancer; however, few studies examine the frequency of multiple patient-reported symptoms. Our aim is to ascertain patient-reported symptom burden at initial consultation with a palliative care provider and compare patient prognostic awareness to provider estimation of prognosis. METHODS Data were extracted from the standardized Quality Data Collection Tool (QDACT). Adults with pancreatic cancer seen by a palliative care provider were included. Descriptive statistics were used to describe demographic features, symptom prevalence and burden, as well as assess patient prognosis awareness defined by congruence or incongruence with provider estimated prognosis. RESULTS 285 patients were included in our analysis. The average age was 68 years (SD: 12.4), 87.2% were white, 50% male. The mean number of moderate/severe symptoms was 2.6 (SD: 2) out of 9 symptoms. Tiredness (66.7%), appetite (64.5%) and pain (46.2%) had the highest rates of moderate/severe symptom burden. Patients with a prognosis of 1-6 months had the lowest proportion of congruence with provider estimation (56.5%). CONCLUSION Our study suggests targets to improve patient-centered care of pancreatic cancer. Patients commonly have multiple symptoms that are moderate/severe at time of palliative care referral. While pain has been well-reported, tiredness and decreased appetite are more prevalent at initial visit. This emphasizes the importance of assessing multiple symptoms and working closely with palliative care for early referral. Overall, one third of patient prognosis estimates differed from the provider assessment of prognosis. Our data support the importance of early referral to palliative care to manage symptoms and better prepare patients for end-of-life care.

Abstract
OBJECTIVE In this study, we examined colorectal cancer (CRC) screening adherence in Medicare beneficiaries and associated healthcare resource utilization (HCRU) and Medicare costs. METHODS Using 20% Medicare random sample data, the study population included Medicare fee-for-service beneficiaries aged 66-75 years on 1 January 2009, at average risk for CRC and continuously enrolled in Medicare Part A/B from 2008 to 2018. We excluded those who had undergone colonoscopy or flexible sigmoidoscopy during 2007-2008 and assumed everyone was due for screening in 2009; screening patterns were determined for 2009-2018. Based on US Preventive Services Task Force recommendations, individuals were categorized as adherent to screening, inadequately screened or not screened. HCRU and Medicare costs were calculated as mean per patient per year (PPPY). RESULTS Of 895,846 eligible individuals, 13.2% were adherent to screening, 53.4% were inadequately screened, and 33.4% were not screened. Compared with those not screened, adherent or inadequately screened individuals were more likely to be female, White and have comorbidities. These individuals also used more healthcare services, generating higher Medicare costs. For example, physician visits were 14.6, 22.9 and 25.9 PPPY and total Medicare costs were $6102, $8469 and $9102 PPPY for those not screened, inadequately screened and adherent, respectively. CONCLUSIONS In Medicare beneficiaries at average risk, adherence to CRC screening was low, although the rate might be underestimated due to lack of early Medicare data. The link between HCRU and screening status suggests that screening initiatives independent of clinical visits may be needed to reach unscreened or inadequately screened individuals.

Abstract
Background This study examined the prevalence of screening and brief intervention (SBI) for alcohol use disorder (AUD) risk in samples of adult drinkers in three middle-income countries (Brazil, China, South Africa), and the extent to which meeting criteria for AUD risk was associated with SBI. Methods Cross-sectional survey data were collected from adult samples in two cities in each country in 2018. Survey measures included past-year alcohol use, the CAGE assessment for AUD risk, talking to a health care professional in the past year, alcohol use screening by a health care professional, receiving advice about drinking from a health care professional, and sociodemographic characteristics. The prevalence of SBI was determined for past-year drinkers in each country and for drinkers who had talked to a health care professional. Logistic regression analyses were conducted to examine whether meeting criteria for AUD risk was associated with SBI when adjusting for sociodemographic characteristics. Results Among drinkers at risk for AUD, alcohol use screening rates ranged from 6.7% in South Africa to 14.3% in Brazil, and brief intervention rates ranged from 4.6% in South Africa to 8.2% in China. SBI rates were higher among drinkers who talked to a health care professional in the past year. In regression analyses, AUD risk was positively associated with SBI in China and South Africa, and with brief intervention in Brazil. Conclusion Although the prevalence of SBI among drinkers at risk for AUD in Brazil, China, and South Africa appears to be low, it is encouraging that these drinkers were more likely to receive SBI.

Abstract
BACKGROUND AND AIMS Postpolypectomy risk stratification for subsequent metachronous advanced neoplasia (MAN) is imprecise and does not account for colonoscopist adenoma detection rate (ADR). Our aim was to assess association of ADR with MAN and create a prediction model for postpolypectomy risk stratification incorporating ADR and other factors. METHODS We conducted a retrospective cohort study of individuals with baseline polypectomy and subsequent surveillance colonoscopy from 2004 to 2016 within the U.S. Department of Veterans Affairs (VA). Clinical factors, polyp findings, and baseline colonoscopist ADR were considered for the model. Model performance (sensitivity, specificity, and area under the curve) for identifying individuals with MAN was compared with 2020 U.S. Multi-Society Task Force on Colorectal Cancer (USMSTF) surveillance recommendations. RESULTS A total of 30,897 individuals were randomly assigned 2:1 into independent model training and validation sets. Increasing age, male sex, diabetes, current smoking, adenoma number, polyp location, adenoma ≥10 mm or with tubulovillous/villous features, and decreasing colonoscopist ADR were independently associated with MAN. A range of 1.48- to 1.66-fold increased risk for MAN was observed for ADR in the lowest 3 quintiles (ADR <19.7%-39.3%) vs the highest quintile (ADR >47.0%). When the final model selected based on the training set was applied to the validation set, improved sensitivity and specificity over 2020 USMSTF risk stratification were achieved (P = .001), with an area under the curve of 0.62 (95% confidence interval, 0.60-0.64). CONCLUSIONS Colonoscopist ADR is associated with MAN. Combining clinical factors and ADR for risk stratification has potential to improve postpolypectomy risk stratification. Improving ADR is likely to improve postpolypectomy outcomes.

Abstract
Background While prevalence of up-to-date screening status is the usual reported statistic, annual screening incidence may better reflect current clinical practices and is more actionable. Our main purpose was to examine incident colorectal cancer (CRC) screening rates in Medicare beneficiaries and to explore characteristics associated with CRC screening. Methods Using 20% Medicare random sample data, the study population included 2016–2018 Medicare fee-for-service beneficiaries covered by Parts A and B aged 66–75 years at average CRC risk. For each study year, we excluded individuals who had a Medicare claim for a colonoscopy within 9 years, flexible sigmoidoscopy within 4 years, and multitarget stool DNA test (mt-sDNA) within 2 years prior; therefore, any observed screening during study year was considered an “incident screening”. Incident screening rates were calculated as number of incident screenings per 1000 Medicare beneficiaries. Overall rates were normalized to 2018 Medicare population distributions of age, sex, and race. Results Each year, > 1.4 million individuals met the inclusion/exclusion criteria from > 6.5 million Medicare beneficiaries. The overall adjusted incident CRC screening rate per 1000 Medicare beneficiaries increased from 85.2 in 2016 to 94.3 in 2018. Incident screening rates decreased 11.4% (22.9 to 20.3) for colonoscopy and 2.4% (58.3 to 56.9) for fecal immunochemical test/guaiac-based fecal occult blood test; they increased 201.5% (6.5 to 19.6) for mt-sDNA. The 2018 unadjusted rate was 76.0 for men and 110.4 for women. By race/ethnicity, the highest 2018 rate was for Asian individuals and the lowest rate was for Black individuals (113.4 and 72.8, respectively). Conclusions The 2016–2018 observed incident CRC screening rate in average-risk Medicare beneficiaries, while increasing, was still low. Our findings suggest more work is needed to improve CRC screening overall and, especially, among male and Black Medicare beneficiaries.

Abstract
Background Little research has examined how pandemics affect residents in under-resourced communities. This study investigated how COVID-19 and lockdown policies affected residents of Alexandra, one of Johannesburg, South Africa's lowest-income townships. Methods We conducted a telephone survey May 11-22, 2020, while the lockdown and alcohol ban were in effect, of a spatially stratified sample of 353 adult Alexandra residents drawn randomly from voter registration, credit card application, and prior studies' sampling frames. We examined economic consequences; health experiences, including COVID-19 exposure and mental health symptoms; alcohol use; and personal experiences with violence. Results Respondents were aged 18 to 89 and 47% female. About 70% of those employed before the lockdown were no longer working. Over half of households lost at least one source of income. About 50% of respondents reported stockpiling food. A majority reported price rises and declines in availability of food. Smaller percentages reported such changes for other items. Over 80% reported stress or anxiety, or depression due to the pandemic. The prevalence of past-week alcohol use fell from over 50% before the lockdown to less than 10% during the lockdown. Self-reported physical violence victimization increased. Discussion COVID-19 and the lockdown disrupted Alexandra residents' lives through unemployment, lost income, mental health problems, and increased violence. The differences between these outcomes and those in more advantaged communities deserve investigation. Research should also seek to identify tailored responses to effectively address the challenges of marginalized communities that often have limited resources to deal with pandemics and policies to contain them.

Abstract
Analysis of stool offers simple, non-invasive monitoring for many gastrointestinal (GI) diseases and access to the gut microbiome, however adherence to stool sampling protocols remains a major challenge because of the prevalent dislike of handling one's feces. We present a technology that enables individual stool specimen collection from toilet wastewater for fecal protein and molecular assay. Human stool specimens and a benchtop test platform integrated with a commercial toilet were used to demonstrate reliable specimen collection over a wide range of stool consistencies by solid/liquid separation followed by spray-erosion. The obtained fecal suspensions were used to perform occult blood tests for GI cancer screening and for microbiome 16S rRNA analysis. Using occult blood home test kits, we found overall 90% agreement with standard sampling, 96% sensitivity and 86% specificity. Microbiome analysis revealed no significant difference in within-sample species diversity compared to standard sampling and specimen cross-contamination was below the detection limit of the assay. Furthermore, we report on the use of an analogue turbidity sensor to assess in real time loose stools for tracking of diarrhea. Implementation of this technology in residential settings will improve the quality of GI healthcare by facilitating increased adherence to routine stool monitoring.

Abstract
OBJECTIVE To examine the healthcare utilization and costs associated with colorectal cancer (CRC) screening by colonoscopy, including costs associated with post-endoscopy events, among average-risk adults covered by Medicaid insurance. METHODS This cohort study evaluated a population of adults (ages 50-75 years) with CRC screening between 1/1/2014 and 12/31/2018 (index = earliest test) from the IBM MarketScan Multi-State Medicaid database. Individuals at above-average risk for CRC or with prior CRC screening were excluded. CRC screening was reported by screening type: colonoscopy, fecal immunochemical test [FIT], fecal occult blood test [FOBT], multi-target stool DNA [mt-sDNA]. Frequency and costs of events potentially related to colonoscopy (defined as occurring within 30 days post-endoscopy) were reported overall, by event type, and by individual event. RESULTS We identified a total of 13,134 average-risk adults covered by Medicaid insurance who received screening by colonoscopy; 63.6% (8350) had Medicare dual-eligibility while 36.4% (4785) did not have Medicare dual-eligibility. The mean (SD) cost of a colonoscopy procedure was $684 ($907) and mean (SD) out-of-pocket costs were $6 ($132). Serious gastrointestinal (GI) events (perforation and bleeding) were observed in 4.6% of individuals with colonoscopy, 4.3% had other GI events, and 3.0% had an incident cardiovascular/cerebrovascular event. Mean (SD) event-related costs were $1233 ($5784) among individuals with a serious GI event, $747 ($1961) among individuals with other GI events, and $4398 ($19,369) among individuals with a cardiovascular/cerebrovascular event. CONCLUSIONS This large, claims-based cohort study reports average (SD) out-of-pocket costs for Medicaid beneficiaries at $6 ($132), which could be one factor contributing to the accessibility of CRC screening by colonoscopy. The incidence of events potentially associated with colonoscopy (i.e. within 30 days after the screening) was 3-4%, and the event-related costs were considerable.

Abstract
DESCRIPTION Proton pump inhibitors (PPIs) are among the most commonly used medications in the world. Developed for the treatment and prevention of acid-mediated upper gastrointestinal conditions, these agents are being used increasingly for indications where their benefits are less certain. PPI overprescription imposes an economic cost and contributes to polypharmacy. In addition, PPI use has been increasingly linked to a number of adverse events (PPI-associated adverse events [PAAEs]). Therefore, de-prescribing of PPIs is an important strategy to lower pill burden while reducing real costs and theoretical risks. The purpose of this clinical update was to provide Best Practice Advice (BPA) statements about how to approach PPI de-prescribing in ambulatory patients. METHODS Our guiding principle was that, although PPIs are generally safe, patients should not use any medication when there is not a reasonable expectation of benefit based on scientific evidence or prior treatment response. Prescribers are responsible for determining whether PPI use is absolutely or conditionally indicated and, when uncertainty exists, to incorporate patient perspectives into PPI decision making. We collaboratively outlined a high-level "process map" of the conceptual approach to de-prescribing PPIs in a clinical setting. We identified the following 3 key domains that required BPA guidance: documentation of PPI indication; identifying suitable candidates for consideration of de-prescribing; and optimizing successful de-prescribing. Co-authors drafted 1 or more potential BPAs, supported by literature review, for each domain. All co-authors reviewed, edited, and selected or rejected draft BPAs for inclusion in the final list submitted to the American Gastroenterological Association Governing Board. Because this was not a systematic review, we did not carry out a formal rating of the quality of evidence or strength of the presented considerations. Best Practice Advice Statements BEST PRACTICE ADVICE 1: All patients taking a PPI should have a regular review of the ongoing indications for use and documentation of that indication. This review should be the responsibility of the patient's primary care provider. BEST PRACTICE ADVICE 2: All patients without a definitive indication for chronic PPI should be considered for trial of de-prescribing. BEST PRACTICE ADVICE 3: Most patients with an indication for chronic PPI use who take twice-daily dosing should be considered for step down to once-daily PPI. BEST PRACTICE ADVICE 4: Patients with complicated gastroesophageal reflux disease, such as those with a history of severe erosive esophagitis, esophageal ulcer, or peptic stricture, should generally not be considered for PPI discontinuation. BEST PRACTICE ADVICE 5: Patients with known Barrett's esophagus, eosinophilic esophagitis, or idiopathic pulmonary fibrosis should generally not be considered for a trial of de-prescribing. BEST PRACTICE ADVICE 6: PPI users should be assessed for upper gastrointestinal bleeding risk using an evidence-based strategy before de-prescribing. BEST PRACTICE ADVICE 7: Patients at high risk for upper gastrointestinal bleeding should not be considered for PPI de-prescribing. BEST PRACTICE ADVICE 8: Patients who discontinue long-term PPI therapy should be advised that they may develop transient upper gastrointestinal symptoms due to rebound acid hypersecretion. BEST PRACTICE ADVICE 9: When de-prescribing PPIs, either dose tapering or abrupt discontinuation can be considered. BEST PRACTICE ADVICE 10: The decision to discontinue PPIs should be based solely on the lack of an indication for PPI use, and not because of concern for PAAEs. The presence of a PAAE or a history of a PAAE in a current PPI user is not an independent indication for PPI withdrawal. Similarly, the presence of underlying risk factors for the development of an adverse event associated with PPI use should also not be an independent indication for PPI withdrawal.

Abstract
BACKGROUND Guidelines include several options for average-risk colorectal cancer (CRC) screening that vary in aspects such as invasiveness, recommended frequency, and precision. Thus, patient and provider preferences can help identify an appropriate screening strategy. This study elicited CRC screening preferences of physicians and individuals at average risk for CRC (IAR). METHODS IAR aged 45-75 years and licensed physicians (primary care or gastroenterology) completed an online discrete choice experiment (DCE). Participants were recruited from representative access panels in the US. Within the DCE, participants traded off preferences between screening type, screening frequency, true-positive, true-negative, and adenoma true positive (physicians only). A mixed logit model was used to obtain predicted choice probabilities for colonoscopy, multi-target stool DNA (mt-sDNA), fecal immunochemical test (FIT), and methylated septin 9 (mSEPT9) blood test. RESULTS Preferences of IAR and physicians were affected by screening precision and screening type. IAR also valued more regular screening. Physicians preferred colonoscopy (96.8%) over mt-sDNA (2.8%; p < 0.001), FIT (0.3%; p < 0.001) and mSEPT9 blood test (0.1%; p < 0.01). IAR preferred mt-sDNA (38.8%) over colonoscopy (32.5%; p < 0.001), FIT (19.2%; p < 0.001), and mSEPT9 blood test (9.4%; p < 0.001). IAR naïve to screening preferred non-invasive screening (p < 0.001), while the opposite was found for those who previously underwent colonoscopy or sigmoidoscopy. CONCLUSIONS While physicians overwhelmingly preferred colonoscopy, preferences of IAR were heterogenous, with mt-sDNA being most frequently preferred on average. Offering choices in addition to colonoscopy could improve CRC screening uptake among IAR. This study used a discrete choice experiment in the US to elicit preferences of physicians and individuals at average risk for colorectal cancer screening modalities and their characteristics.

Abstract
OBJECTIVE To examine the healthcare costs associated with colorectal cancer (CRC) screening and the frequency and costs of events potentially related to colonoscopy among average-risk adults. METHODS In this cohort study, adults (ages 50-75 years) with CRC screening between 1/1/2014 and 6/30/2019 (index = earliest test) were selected from the IBM MarketScan Research databases. Individuals at above-average risk for CRC or with prior CRC screening were excluded. Frequency of utilization was reported by screening type: colonoscopy, fecal immunochemical test (FIT), fecal occult blood test (FOBT), multi-target stool DNA (mt-sDNA). For colonoscopy, frequency and costs of potential events were reported overall, by event type, and by an individual event in the 30 days after colonoscopy. RESULTS Among the 333,306 average-risk adults, colonoscopy was the most common CRC screening modality (70.6%), followed by FIT (17.7%), FOBT (8.1%), and mt-sDNA (3.2%). The mean cost of a colonoscopy procedure was $2,125 and the mean out-of-pocket costs were $79. Serious gastrointestinal (GI) events were observed in 1.3% of individuals with colonoscopy, 1.9% had other GI events, and 1.2% had an incident cardiovascular event. Mean event-related costs were $2,631 among individuals with a serious GI event, $1,774 among individuals with any other GI event, and $4,234 among individuals with a cardiovascular event. CONCLUSIONS This study provides updated and more detailed information regarding the costs of CRC screening and potential colonoscopy events based on a comprehensive review of a robust claims dataset.

Abstract
65 Background: There is consensus that the proportion of the average-risk US population up-to-date with CRC screening (58-65%) is insufficient. However, estimates of average risk CRC screening rates are inconsistent and impacted by inclusion of higher-risk individuals, and differing study designs. Accurate measurement of population screening rates is key to addressing gaps in care and assessing the impact of newer CRC screening tests. Methods: The study included individuals aged 50-75 years in a large de-identified claims database, with continuous enrollment during year of analysis, and a variable length baseline enrollment of 1-10 years. Average-risk designation excluded higher risk diagnoses (CRC familial syndromes, colorectal polyp or history of colorectal polyp, history of/current CRC, family history of gastrointestinal cancer, and inflammatory bowel disease). Up-to-date status was assessed within guideline-based time periods: colonoscopy (10 years); FIT or FOBT (annually); mt-sDNA (3 years); flexible sigmoidoscopy/CT colonography (5 years). Analyses assessed the proportion estimated as up-to-date and examined the sensitivity to: a) patient population (average-risk only vs. including higher-risk); b) study design (yearly cross-sectional vs. cohort of 50-year-old patients; c) methods (percent in patients with 10 years of enrollment vs. Kaplan Meier (KM) of censored variable pre-screening period). Results: The cross-sectional analysis average-risk population included 5.3 million individuals. Estimates of the proportion of those up-to-date with screening guidelines for average-risk patients varied by study design, population, and estimation method. KM estimates among the average-risk population (50-75) showed 49-50% were up-to-date in each calendar year. Including higher-risk patients in the KM analysis resulted in 70% up-to-date among the mixed average+higher-risk population. Using a cohort study design (average-risk patients aged 60 with 10 years of baseline data), 65% were up-to-date by age 60. Conclusions: In the base case analysis only half of average risk individuals were up-to-date with CRC screening, a rate lower than typically cited. Sensitivity analyses resulted in substantially different estimates and demonstrate the importance of clearly communicating the methodology used to define the study population. Higher rates quoted in the lay press and medical publications may be based on mixed populations of average+higher-risk individuals or on study designs that do not represent the full population at risk.

Abstract
PURPOSE This study examined adherence to screening for fecal immunochemical test (FIT). METHODS Adults (≥ 50-75) with a FIT between 1/1/2014 and 6/30/2019 in MarketScan administrative claims were selected (index = earliest FIT). Patients were followed for 10 years pre- and 3 years post-index. Patients at increased risk for CRC or with prior screening were excluded. Year over year adherence was measured post-index. RESULTS Of 10,253 patients, the proportion adherent to repeat testing at year 2 was 23.4% and 10.6% at year 3. Of 76.6% not adherent in year 2, 5.4% were adherent in year 3. CONCLUSION Results suggest adherence to FIT tests is poor, minimizing potential benefits. Future studies are needed to consider alternative test options and whether more choice will improve long-term adherence.

Abstract
IMPORTANCE Colorectal cancer (CRC) screening reduces CRC incidence and mortality. It is important to examine screening patterns over time, including after the introduction of new screening modalities. OBJECTIVE To compare use of CRC screening tests before and after the availability of the multitarget stool DNA (mt-sDNA) test, given that endorsed options have changed. DESIGN, SETTING, AND PARTICIPANTS This longitudinal cohort study used administrative claims data to examine CRC screening use in 2 discrete periods: before (August 1, 2011, to July 31, 2014) and after (August 1, 2016, to July 31, 2019) the mt-sDNA test became available. The MarketScan Commercial and Medicare Supplemental databases were queried for individuals aged 45 to 75 years between August 1, 2011, and July 31, 2019, with average risk of CRC and with continuous enrollment in the databases from August 1, 2001, to July 31, 2019. MAIN OUTCOMES AND MEASURES The proportion of individuals up to date or not due for CRC screening during each measurement year and the type of screening test used among individuals due for screening. Data were reported overall and among individuals aged 45 to 49 or 50 years and older on August 1, 2011. RESULTS A total of 97 776 individuals with average risk were identified. Individuals had a mean (SD) age of 50.8 (3.5) years, and 54 227 (55.5%) were women. The proportion of individuals with average risk aged 50 to 75 years with commercial or Medicare supplemental insurance who were up to date with CRC screening increased from 50.4% in 2011 (30 605 of 60 770) to 69.7% in 2019 (42 367 of 60 770). Among individuals due for screening and screened, the use of high-sensitivity fecal occult blood test (FOBT) decreased between 2011 (1088 of 6241 eligible individuals [17.7%]) and 2019 (195 of 2943 eligible individuals [6.6%]), and the use of mt-sDNA increased between 2016 (58 of 3014 eligible individuals [1.9%]) and 2019 (418 of 2943 eligible individuals [14.2%]). No consistent trends were observed with fecal immunochemical test (FIT) or screening colonoscopy. Computed tomography colonography, double-contrast barium enema, and flexible sigmoidoscopy were rarely performed. CONCLUSIONS AND RELEVANCE In this cohort study, the proportion of individuals with average risk who were up to date with CRC screening increased between 2011 and 2019 but remained suboptimal. There were no substantial changes in the use of the colonoscopy or FIT; however, there was an increase in the adoption of mt-sDNA and a decrease in the use of FOBT during the study period.

Abstract
BACKGROUND Research on the effects of restricting bar opening hours and alcohol sales in middle-income countries is very limited. We assessed compliance with and possible effects of a law enacted in Zacatecas, Mexico on December 30, 2017 and implemented in 2018 and 2019 that established a 2 AM bar closing time and 10 PM cut-off for alcohol sales by off-premises stores. METHODS Monthly observations of bars and off-premises stores and alcohol mystery shopping visits from 2018 to early 2020 were conducted to assess compliance with the law. Breath tests were conducted in 2018 and 2019 with samples of pedestrians in the nighttime entertainment districts of Zacatecas and a comparison city (Aguascalientes). Surveys of bar owners/managers and staff, emergency medical personnel (EMP), and police officers were conducted in Zacatecas in 2018 and 2019 to assess awareness and support of the law and possible effects of the law on alcohol-related problems such as violence and injuries. RESULTS Monthly observations indicated that a substantial percentage of bars and off-premises package stores did not comply with the law. Pedestrian breath tests in 2018 and 2019 indicated significant reductions in blood alcohol concentration and heavy drinking among pedestrians in Zacatecas from 11 PM to 2 AM compared to Aguascalientes, but not after 2 AM. Surveys of bar owners/managers indicated that most were aware and supportive of the law. EMP surveys indicated reductions in incidents of physical fighting and drunk or injured customers during the annual September fair in Zacatecas. CONCLUSIONS This study suggests that restricting bar opening hours and alcohol sales may not result in full compliance by bars and off-premises stores, but may help to reduce excessive alcohol use and related harms in a middle-income country. A more rigorous evaluation with pre-intervention data is needed, however, to fully address this latter question.

Abstract
AIMS While most guidelines still recommend colorectal cancer (CRC) screening initiation at age 50 years in average-risk individuals, guideline-creating bodies are starting to lower the recommended age of initiation to 45 years to mitigate the trend of increasing CRC rates in younger populations. Using CRC-AIM, we modeled the impact of lowering the CRC screening initiation age, incorporating theoretical and reported adherence rates, for triennial multi-target stool DNA (mt-sDNA) or annual fecal immunochemical test (FIT) screening. METHODS AND MATERIALS Screening strategies were simulated for individuals without CRC at age 40 and screened from ages 50 to 75 or 45 to 75 years. Outcomes included CRC incidence, CRC mortality, and life-years gained (LYG) per 1000 individuals screened (compared with no screening). Models used theoretically perfect (100%) and previously reported (71% mt-sDNA; 43% FIT) adherence rates. RESULTS With perfect adherence, mt-sDNA and FIT resulted in 22.2 and 23.4 more predicted LYG, respectively, with screening initiation at age 45 versus 50 years; reported adherence resulted in 23.9 and 24.4 more LYG, respectively. With perfect adherence, screening initiation at age 45 versus 50 years resulted in 26.1 and 28.6 CRC cases, respectively, with mt-sDNA and 22.8 and 25.5 cases with FIT; with reported real-world adherence there were 28.5 and 31.2 cases, respectively, with mt-sDNA and 37.1 and 40.2 cases with FIT. Similar patterns were observed for CRC deaths. With screening initiation at age 45 and reported adherence, mt-sDNA averted 8.6 more CRC cases and 3.3 more deaths per 1000 individuals than FIT. CONCLUSIONS Estimated CRC screening outcomes improved by lowering the initiation age from 50 to 45 years. Incorporating reported adherence rates yields greater benefits from triennial mt-sDNA versus annual FIT screening.

Abstract
Colorectal cancer-screening models commonly assume 100% adherence, which is inconsistent with real-world experience. The influence of adherence to initial stool-based screening [fecal immunochemical test (FIT), multitarget stool DNA (mt-sDNA)] and follow-up colonoscopy (after a positive stool test) on colorectal cancer outcomes was modeled using the Colorectal Cancer and Adenoma Incidence and Mortality Microsimulation Model. Average-risk individuals without diagnosed colorectal cancer at age 40 undergoing annual FIT or triennial mt-sDNA screening from ages 50 to 75 were simulated. Primary analyses incorporated published mt-sDNA (71%) or FIT (43%) screening adherence, with follow-up colonoscopy adherence ranging from 40% to 100%. Secondary analyses simulated 100% adherence for stool-based screening and colonoscopy follow-up (S1), published adherence for stool-based screening with 100% adherence to colonoscopy follow-up (S2), and published adherence for both stool-based screening and colonoscopy follow-up after positive mt-sDNA (73%) or FIT (47%; S3). Outcomes were life-years gained (LYG) and colorectal cancer incidence and mortality reductions (per 1,000 individuals) versus no screening. Adherence to colonoscopy follow-up after FIT had to be 4%-13% higher than mt-sDNA to reach equivalent LYG. The theoretical S1 favored FIT versus mt-sDNA (LYG 316 vs. 297; colorectal cancer incidence reduction 68% vs. 64%; colorectal cancer mortality reduction 76% vs. 72%). The more realistic S2 and S3 favored mt-sDNA versus FIT (S2: LYG 284 vs. 245, colorectal cancer incidence reduction 61% vs. 50%, colorectal cancer mortality reduction 69% vs. 59%; S3: LYG 203 vs. 113, colorectal cancer incidence reduction 43% vs. 23%, colorectal cancer mortality reduction 49% vs. 27%, respectively). Incorporating realistic adherence rates for colorectal cancer screening influences modeled outcomes and should be considered when assessing comparative effectiveness. PREVENTION RELEVANCE: Adherence rates for initial colorectal cancer screening by FIT or mt-sDNA and for colonoscopy follow-up of a positive initial test influence the comparative effectiveness of these screening strategies. Using adherence rates based on published data for stool-based testing and colonoscopy follow-up yielded superior outcomes with an mt-sDNA versus FIT-screening strategy.

Abstract
BACKGROUND Colorectal cancer (CRC) screening (CRCS) facilitates early detection and lowers CRC mortality. OBJECTIVES To increase CRCS in a randomized trial of stepped interventions. Step 1 compared three modes of delivery of theory-informed minimal cue interventions. Step 2 was designed to more intensively engage those not completing CRCS after Step 1. METHODS Recruitment packets (60,332) were mailed to a random sample of individuals with a record of U.S. military service during the Vietnam-era. Respondents not up-to-date with CRCS were randomized to one of four Step 1 groups: automated telephone, telephone, letter, or survey-only control. Those not completing screening after Step 1 were randomized to one of three Step 2 groups: automated motivational interviewing (MI) call, counselor-delivered MI call, or Step 2 control. Intention-to-treat (ITT) analyses assessed CRCS on follow-up surveys mailed after each step. RESULTS After Step 1 (n = 1784), CRCS was higher in the letter, telephone, and automated telephone groups (by 1%, 5%, 7%) than in survey-only controls (43%), although differences were not statistically significant. After Step 2 (n = 516), there were nonsignificant increases in CRCS in the two intervention groups compared with the controls. CRCS following any combination of stepped interventions overall was 7% higher (P = 0.024) than in survey-only controls (55.6%). CONCLUSIONS In a nationwide study of Veterans, CRCS after each of two stepped interventions of varying modes of delivery did not differ significantly from that in controls. However, combined overall, the sequence of stepped interventions significantly increased CRCS.

Abstract
BACKGROUND Real-world data for patients with positive colorectal cancer (CRC) screening stool-tests demonstrate that adenoma detection rates are lower when endoscopists are blinded to the stool-test results. This suggests adenoma sensitivity may be lower for screening colonoscopy than for follow-up to a known positive stool-based test. Previous CRC microsimulation models assume identical sensitivities between screening and follow-up colonoscopies after positive stool-tests. The Colorectal Cancer and Adenoma Incidence and Mortality Microsimulation Model (CRC-AIM) was used to explore the impact on screening outcomes when assuming different adenoma sensitivity between screening and combined follow-up/surveillance colonoscopies. METHODS Modeled screening strategies included colonoscopy every 10 years, triennial multitarget stool DNA (mt-sDNA), or annual fecal immunochemical test (FIT) from 50 to 75 years. Outcomes were reported per 1000 individuals without diagnosed CRC at age 40. Base-case adenoma sensitivity values were identical for screening and follow-up/surveillance colonoscopies. Ranges of adenoma sensitivity values for colonoscopy performance were developed using different slopes of odds ratio adjustments and were designated as small, medium, or large impact scenarios. RESULTS As the differences in adenoma sensitivity for screening versus follow-up/surveillance colonoscopies became greater, life-years gained (LYG) and reductions in CRC-related incidence and mortality versus no screening increased for mt-sDNA and FIT and decreased for screening colonoscopy. The LYG relative to screening colonoscopy reached >90% with FIT in the base-case scenario and with mt-sDNA in a "medium impact" scenario. CONCLUSIONS Assuming identical adenoma sensitivities for screening and follow-up/surveillance colonoscopies underestimate the potential benefits of stool-based screening strategies.

Abstract
BACKGROUND This study examined the relative contribution of alcoholic beverage types to overall alcohol consumption and associations with heavy alcohol use and alcohol-related harms among adults. METHODS Cross-sectional survey data were collected from adult samples in two cities involved in the Global Smart Drinking Goals (GSDG) initiative in each of five countries (Belgium, Brazil, China, South Africa, United States). Survey measures included past-30-day consumption of beer, wine, flavored alcoholic drinks, spirits, and homemade alcohol; past-30-day heavy drinking; 14 alcohol-related harms in the past 12 months; and demographic characteristics. Within in each country, we computed the proportion of total alcohol consumption for each beverage type. Regression analyses were conducted to estimate the relative associations between consumption of each alcoholic beverage type, heavy alcohol use, and alcohol-related harms, controlling for demographic characteristics. RESULTS Beer accounted for at least half of total alcohol consumption in GSDG cities in Belgium, Brazil, the U.S., and South Africa, and 35% in China. Regression analyses indicated that greater beer consumption was associated with heavy drinking episodes and with alcohol-related harms in the cities in Belgium, Brazil, South Africa, and the U.S. Significant increases in heavy drinking and alcohol-related harms were also consistently observed for spirits consumption. CONCLUSIONS Beer accounts for the greatest proportion of total alcohol consumption in most of the GSDG cities and was consistently associated with more heavy drinking episodes and alcohol-related harms. Reducing beer consumption through evidence-based interventions may therefore have the greatest impact on hazardous drinking and alcohol-related harms.

Abstract
Little is known about adults in China who drink homemade alcohol, and whether they are at elevated risk of harms relative to those who drink alcohol from commercial sources. Purpose: We describe and contrast adults in China who regularly consume either homemade or commercially available alcohol, or both. Methods: Household-based in-person interviews were conducted in 2018 with adults in Jiangshan and Lanxi. We examined the characteristics of 833 adults who had consumed alcohol within the previous 30 days, comparing those who drank commercial alcohol only with those who drank homemade alcohol only and alcohol from both sources. Results: Regression analyses revealed that drinkers of both homemade and commercial alcohol consumed more drinks and were more likely to report heavy drinking than did drinkers of commercial or homemade alcohol only and were also more likely to meet criteria for alcohol use disorder. We also found that homemade-only alcohol drinkers were at elevated risk for this disorder. Conclusions: Drinkers of both homemade and commercial alcohol in China may be at risk for alcohol-related problems and constitute a little understood population for whom further research is needed.

Abstract
AIM Multiple screening strategies are guideline-endorsed for average-risk colorectal cancer (CRC). The impact of real-world adherence rates on the cost-effectiveness of non-invasive stool-based CRC screening strategies remains undefined. METHODS This cost-effectiveness analysis from the perspective of Medicare as a primary payer used the Colorectal Cancer and Adenoma Incidence and Mortality Microsimulation Model (CRC-AIM) to estimate cost and clinical outcomes for triennial multi-target stool DNA (mt-sDNA), annual fecal immunochemical test (FIT) and annual fecal occult blood test (FOBT) screening strategies in a simulated cohort of US adults aged 65 years, who were assumed to either be previously unscreened or initiating screening upon entry to Medicare. Reported real-world adherence rates for initial stool-based screening and colonoscopy follow up (after a positive stool test result) were defined as 71.1% and 73.0% for mt-sDNA, 42.6% and 47.0% for FIT, and 33.4% and 47.0% for FOBT, respectively. The incremental cost-effectiveness ratio using quality-adjusted life years (QALY) was defined as the primary outcome of interest; other cost and clinical outcomes were also reported in secondary analyses. Multiple sensitivity and scenario analyses were conducted. RESULTS When reported real-world adherence rates were included only for initial stool-based screening, mt-sDNA was cost-effective versus FIT ($62,814/QALY) and FOBT ($39,171/QALY); mt-sDNA also yielded improved clinical outcomes. When reported real-world adherence rates were included for both initial stool-based screening and follow-up colonoscopy (when indicated), mt-sDNA was increasingly cost-effective compared to FIT and FOBT ($31,725/QALY and $28,465/QALY, respectively), with further improved clinical outcomes. LIMITATIONS Results are based on real-world cross-sectional adherence rates and may vary in the context of other types of settings. Only guideline-recommended stool-based strategies were considered in this analysis. CONCLUSION Comparisons of the effectiveness and benefits of specific CRC screening strategies should include both test-specific performance characteristics and real-world adherence to screening tests and, when indicated, follow-up colonoscopy.

Abstract
This study investigated whether the presence of school-based health centers (SBHCs) was associated with six substance use behaviors among sexual minority youth (SMY) and their heterosexual peers. Data from the 2015 Oregon Healthy Teens Survey, including 13,608 11th graders in 137 schools (26 with SBHCs) were used in the current study. Multilevel logistic regression analyses were performed. Results revealed significant SBHC by SMY status interactions indicating a relatively lower likelihood of past 30-day alcohol use (23%), binge drinking (43%), use of e-cigarettes (22%), marijuana (44%), and unprescribed prescription drugs (28%) among SMY in SBHC schools compared with non-SMY at SBHC schools. Furthermore, SMY in SBHC schools reported lower likelihood of aforementioned substance use behaviors than SMY attending non-SBHC schools. Conversely, no differences in these outcomes were observed for non-SMY in SBHC and non-SBHC schools. Findings from this study suggest SBHCs may help to mitigate substance use disparities among marginalized populations, such as SMY.

Abstract
We report the results of a quasi-experimental evaluation of a mystery shopper intervention in Zacatecas and Guadalupe, Mexico. Underage youth attempted to purchase beer at 50 Modelorama stores and 32 Oxxo stores (intervention groups), and at 19 comparison convenience stores in March, July, and August 2018. After each attempt, intervention store operators were informed if a sale was made. Modelorama operators also received training and were warned that repeated sales to minors could jeopardize their franchise. Average sales rates to minors were 63.8% at Modeloramas, 86.5% at Oxxo stores, and 98.2% at comparison stores. The findings suggest that mystery shopper interventions with training, feedback to store operators, and sanctions after repeated sales to underage youth may reduce sales to minors in low- and middle-income countries.

Abstract
Gastroesophageal reflux disease and esophageal dysmotility are common in patients with advanced lung disease (ALD) and are associated with worse outcomes. Assessing esophageal function in these patients is relevant for determining pulmonary transplant eligibility and prognosticating post-transplant outcomes. Barium Swallow (BaS) is a non-invasive testing modality often performed as a complement to formal esophageal function tests (EFTs), but its role and clinical utility in this context is unknown. Therefore, we aimed to determine the relationship between BaS and EFTs with high-resolution manometry (HRM) and 24-h ambulatory pH-metry in patients with ALD. We performed a retrospective study of 226 consecutive patients undergoing evaluation for lung transplantation at a single center. All patients underwent EFTs and BaS independent of clinical history or symptoms per institutional protocol. Appropriate statistical tests were performed to evaluate the relationship between EFTs and BaS. Mucosal, reflux and motility findings were categorized. Abnormal motility was reported in 133 (59%) patients by BaS and 99 (44%) by HRM, with a significant difference in the proportions of patients with abnormal studies (p < 0.01). There were 7 (26%) patients with abnormal barium tablet passage who had normal HRM. The sensitivity (35%) and specificity (77%) for detecting pathologic reflux with BaS was poor. Inducibility of reflux and barium column height were not associated with pH-metry results. No clinically significant luminal irregularities were identified. In conclusion, while BaS can non-invasively assess esophageal mucosa, its findings are not associated with EFTs in patients with ALD.

Abstract
OBJECTIVE Despite the rising toll of drug poisoning deaths in the United States, the extent of the problem among adolescents and young adults ages 15-24 years has received relatively little attention. We examined sociodemographic characteristics and state trends in drug poisoning deaths among adolescents and young adults from 2006 to 2015 and estimated the costs of drug poisoning mortality in this population. METHOD We used the National Vital Statistics System's Multiple Cause of Death files from 2006 to 2015. We analyzed trends using Joinpoint regression analysis and calculated total costs of drug poisoning deaths, including medical costs, work loss costs, and quality of life loss, based on widely used cost estimates. RESULTS Drug poisoning death rates (per 100,000 population) in adolescents and young adults increased from 8.1 in 2006 to 9.7 in 2015. The rates increased significantly for Whites (1.7% per year) and Asian/Pacific Islanders (4.3% per year) from 2006 to 2015 and for Blacks (11.8% per year) from 2009 to 2015. By U.S. region, the rates increased significantly in the Midwest (4.4% per year) from 2006 to 2015 and in the Northeast (11.0% per year) from 2009 to 2015. Trends varied by age group, intent for drug poisoning, drug category (i.e., opioids, pharmaceutical drugs excluding opioids, illicit drugs excluding opioids, and unspecified drugs), urbanization level, and state. The estimated costs of drug poisoning deaths among adolescents and young adults totaled approximately $35 billion in 2015. CONCLUSIONS Trends in drug poisoning deaths and estimated costs inform state-specific prevention and intervention efforts.

Abstract
OBJECTIVES A history of gastrointestinal bleeding (GIB) in patients with atrial fibrillation (AF) may impact decisions about anticoagulation treatment. We sought to determine whether prior GIB in patients with AF taking anticoagulants was associated with an increased risk of stroke or major hemorrhage. METHODS We analyzed key efficacy and safety outcomes in patients with prior GIB in ARISTOTLE. Centrally adjudicated outcomes according to GIB history were analyzed using Cox proportional hazards models adjusted for randomized treatment and established risk factors. RESULTS A total of 784 (4.3%) patients had prior GIB events (321 [41%] lower, 463 [59%] upper); 215 (27%) occurred <1 year before study enrollment. Patients with prior GIB were older, had more comorbidities, and higher CHADS2 and HAS-BLED scores than those with no GIB. Major GIB occurred more frequently in those with prior GIB (lower: aHR 1.72, 95% CI 0.86-3.42; upper: aHR 3.13, 95% CI 1.97-4.96). This association with major GIB was more pronounced in patients with GIB <1 year before randomization versus no recent GIB (recent lower: aHR 2.58, 95% CI 0.95-7.01; recent upper: aHR 5.16, 95% CI 2.66-10.0). There was no association between prior GIB and risk of stroke/systemic embolism or all-cause death. In those with prior GIB, the apixaban versus warfarin relative risks for stroke/systemic embolism, hemorrhagic stroke, death, or major bleeding were consistent with the results of the overall trial. CONCLUSIONS In patients with AF on oral anticoagulants, prior GIB was associated with an increased risk of subsequent major GIB but not stroke, intracranial bleeding, or all-cause mortality. For the key outcomes of stroke, hemorrhagic stroke, death, and major bleeding, we found no evidence that the treatment effect (apixaban vs. warfarin) was modified by a history of GIB.

Abstract
Alcohol remains readily available to youth in most countries. We examined the associations between both the on- and off-premises commercial availability of alcohol to youth and their alcohol use, heavy episodic drinking, and alcohol-related harms. We conducted the study using data from a survey of a sample of 594 students in central Mexico between 12 and 17 years of age in 2016. Both the perceived availability of alcohol and the purchasing of alcohol at an off-premises establishment were positively related to past-30-day alcohol use and heavy episodic drinking, as well as to alcohol-related harms in the past year. Consumption at on-premises establishments was also positively associated with alcohol-related harms. Preventive efforts to reduce the availability of alcohol at off- and on-premises establishments, by such strategies as mystery shopper and responsible beverage service programs, are imperative.

Abstract
This study's purpose was to examine whether school-based health centers (SBHCs) support mental health indicators among sexual minority youth (SMY). Data came from the 2015 Oregon Healthy Teens Survey with 13,608 11th graders in 137 public high schools in Oregon. Regression results revealed significant SBHC by SMY status interactions indicating relative reductions in likelihood of depressive episodes (30%), suicidal ideation (34%), and suicide attempts (43%) among SMY in schools with SBHCs. SMY students in SBHC schools reported lower likelihood of a past-year depressive episode, suicidal ideation, and suicide attempt versus those attending non-SBHC schools. Conversely, no differences in these outcomes were observed for non-SMY by SBHC status. SBHCs may help reduce mental health disparities among SMY, a marginalized, underserved population.

Abstract
BACKGROUND Approximately 38% of patients with colorectal cancer will develop isolated liver metastases. Sidedness of colon tumor is identified in non-metastatic and unresected metastatic cancers as predictive of survival, yet its dedicated analysis in resected liver metastases is minimal. Our primary aim was to assess whether left-sided primary tumors improve prognosis in stage IV cancer patients undergoing curative-intent liver metastasectomy; it was hypothesized that it would. METHODS This is a retrospective, observational cohort study from 1996 to 2016 in a single tertiary-care facility. Survival from diagnosis was calculated via Kaplan-Meier method and compared between the right and left sides via log-rank analysis. RESULTS Median survival differs significantly between colorectal tumors of the right and left origins after hepatic metastasectomy in 612 patients. In patients with right-sided tumors, median survival from diagnosis was 4.5 years (IQR 4.1-5.3), and 6.3 years (IQR 5.6-6.9) in those with left tumors (HR 1.5, 95% CI 1.38-1.60, p < 0.001). CONCLUSION As in studies on earlier-stage or unresected metastatic disease, tumor sidedness is an important prognostic factor in patient survival with liver metastasectomy. Clinical risk scores should include side of primary tumor. Further work is needed to determine the molecular basis for this difference.

Abstract
Abstract
We developed dioxatane-based immunochemiluminometric assays (ICMAs) for lutropin (LH) and follitropin (FSH), using monoclonal antibodies. These ICMAs have a minimal detectable dose (analytical sensitivity) of 0.01 IU/L, extending the lower limit of sensitivity 10-fold (from 0.10 IU/L) when compared with immunoradiometric assays (IRMA) (second generation), and thus provide a true third-generation assay. Daytime FSH and LH concentrations were measured in 236 boys and 195 girls. Unlike the previous assays, all the samples had detectable concentrations of LH and FSH. In agreement with results from earlier methods, the present results indicate that for both sexes mean FSH and LH concentrations are relatively high during the early months of life, fall to baseline prepubertal concentrations by 12-18 months, and remain low until the onset of puberty. During puberty, the mean concentrations of FSH and LH increase significantly in both girls and boys with each stage of puberty, but there is considerable overlap between stages. These third-generation FSH and LH ICMAs reliably separate daytime plasma FSH and LH concentrations of prepubertal children from those of sexually mature children, and therefore can more reliably distinguish between the major causes of precocious puberty (e.g., gonadotropin dependent and independent). Our LH assay is also useful in monitoring the gonadotropin-releasing hormone therapy of patients with gonadotropin-dependent precocious puberty.

Abstract
Spatially resolved diffuse reflectance spectroscopy (SRDRS) is a promising technique for characterization of colon tissue. Herein, two methods for extracting the reduced scattering and absorption coefficients ( μ s ' ( λ ) and μ a ( λ ) ) from SRDRS data using lookup tables of simulated diffuse reflectance are reported. Experimental measurements of liquid tissue phantoms performed with a custom multi-pixel silicon SRDRS sensor spanning the 450 - 750 nm wavelength range were used to evaluate the extraction methods, demonstrating that the combined use of spatial and spectral data reduces extraction error compared to use of spectral data alone. Additionally, SRDRS measurements of normal and tumor ex-vivo human colon tissue are presented along with μ s ' ( λ ) and μ a ( λ ) extracted from these measurements.

Abstract
Background Colorectal cancer is the fourth most commonly diagnosed cancer in the United States. Approximately 3–10% of the population has an increased risk for colorectal cancer due to family history and warrants more frequent or intensive screening. Yet, < 50% of that high-risk population receives guideline-concordant care. Systematic collection of family health history and decision support may improve guideline-concordant screening for patients at increased risk of colorectal cancer. We seek to test the effectiveness of a web-based, systematic family health history collection tool and decision support platform (MeTree) to improve risk assessment and appropriate management of colorectal cancer risk among patients in the Department of Veterans Affairs primary care practices. Methods In this ongoing randomized controlled trial, primary care providers at the Durham Veterans Affairs Health Care System and the Madison VA Medical Center are randomized to immediate intervention or wait-list control. Veterans are eligible if assigned to enrolled providers, have an upcoming primary care appointment, and have no conditions that would place them at increased risk for colorectal cancer (such as personal history, adenomatous polyps, or inflammatory bowel disease). Those with a recent lower endoscopy (e.g. colonoscopy, sigmoidoscopy) are excluded. Immediate intervention patients put their family health history information into a web-based platform, MeTree, which provides both patient- and provider-facing decision support reports. Wait-list control patients access MeTree 12 months post-consent. The primary outcome is the risk-concordant colorectal cancer screening referral rate obtained via chart review. Secondary outcomes include patient completion of risk management recommendations (e.g. colonoscopy) and referral for genetic consultation. We will also conduct an economic analysis and an assessment of providers’ experience with MeTree clinical decision support recommendations to inform future implementation efforts if the intervention is found to be effective. Discussion This trial will assess the feasibility and effectiveness of patient-collected family health history linked to decision support to promote risk-appropriate screening in a large healthcare system such as the Department of Veterans Affairs.

Abstract
PURPOSE Cancer ascertainment using large-scale electronic health records is a challenge. Our aim was to propose and apply a structured approach for evaluating multiple candidate approaches for cancer ascertainment using colorectal cancer (CRC) ascertainment within the US Department of Veterans Affairs (VA) as a use case. METHODS The proposed approach for evaluating cancer ascertainment strategies includes assessment of individual strategy performance, comparison of agreement across strategies, and review of discordant diagnoses. We applied this approach to compare three strategies for CRC ascertainment within the VA: administrative claims data consisting of International Classification of Diseases, Ninth Revision (ICD9) diagnosis codes; the VA Central Cancer Registry (VACCR); and the newly accessible Oncology Domain, consisting of cases abstracted by local cancer registrars. The study sample consisted of 1,839,043 veterans with index colonoscopy performed from 1999 to 2014. Strategy-specific performance was estimated based on manual record review of 100 candidate CRC cases and 100 colonoscopy controls. Strategies were further compared using Cohen's κ and focused review of discordant CRC diagnoses. RESULTS A total of 92,197 individuals met at least one CRC definition. All three strategies had high sensitivity and specificity for incident CRC. However, the ICD9-based strategy demonstrated poor positive predictive value (58%). VACCR and Oncology Domain had almost perfect agreement with each other (κ, 0.87) but only moderate agreement with ICD9-based diagnoses (κ, 0.51 and 0.57, respectively). Among discordant cases reviewed, 15% of ICD9-positive but VACCR- or Oncology Domain-negative cases had incident CRC. CONCLUSION Evaluating novel strategies for identifying cancer requires a structured approach, including validation against manual record review, agreement among candidate strategies, and focused review of discordant findings. Without careful assessment of ascertainment methods, analyses may be subject to bias and limited in clinical impact.

Abstract
Patients diagnosed with advanced stages of gastrointestinal (GI) malignancies are often quite symptomatic, with symptoms primarily related to anatomic sites of obstruction. Endoscopic approaches to the palliation of GI malignancies have begun to overtake surgical approaches as first line in interventional management. We brought together a team of interventional gastroenterologists and palliative care experts to collate practical pearls for the types of endoscopic interventions used for symptom management in patients with GI malignancies. In this article, we use a "Top 10" format to highlight issues that may help palliative care physicians recognize common presentations of advanced GI malignancies, address interventional approaches to improve symptom burden, and improve the quality of shared decision making and goals-of-care discussions.

Abstract
OBJECTIVE To describe a framework for leveraging big data for research and quality improvement purposes and demonstrate implementation of the framework for design of the Department of Veterans Affairs (VA) Colonoscopy Collaborative. METHODS We propose that research utilizing large-scale electronic health records (EHRs) can be approached in a 4 step framework: 1) Identify data sources required to answer research question; 2) Determine whether variables are available as structured or free-text data; 3) Utilize a rigorous approach to refine variables and assess data quality; 4) Create the analytic dataset and perform analyses. We describe implementation of the framework as part of the VA Colonoscopy Collaborative, which aims to leverage big data to 1) prospectively measure and report colonoscopy quality and 2) develop and validate a risk prediction model for colorectal cancer (CRC) and high-risk polyps. RESULTS Examples of implementation of the 4 step framework are provided. To date, we have identified 2,337,171 Veterans who have undergone colonoscopy between 1999 and 2014. Median age was 62 years, and 4.6 percent (n = 106,860) were female. We estimated that 2.6 percent (n = 60,517) had CRC diagnosed at baseline. An additional 1 percent (n = 24,483) had a new ICD-9 code-based diagnosis of CRC on follow up. CONCLUSION We hope our framework may contribute to the dialogue on best practices to ensure high quality epidemiologic and quality improvement work. As a result of implementation of the framework, the VA Colonoscopy Collaborative holds great promise for 1) quantifying and providing novel understandings of colonoscopy outcomes, and 2) building a robust approach for nationwide VA colonoscopy quality reporting.

Abstract
Early detection and surveillance of disease progression in epithelial tissue is key to improving long term patient outcomes for colon and esophageal cancers, which account for nearly a quarter of cancer related mortalities worldwide. Spatially resolved diffuse reflectance spectroscopy (SRDRS) is a non-invasive optical technique to sense biological changes at the cellular and sub-cellular level that occur when normal tissue becomes diseased, and has the potential to significantly improve the current standard of care for endoscopic gastrointestinal (GI) screening. Herein the design, fabrication, and characterization of the first custom SRDRS device to enable endoscopic SRDRS GI tissue characterization using a custom silicon (Si) thin film multi-pixel endoscopic optical sensor (MEOS) is described.

Abstract
The objective of the current study was to explore demographic, financial, and psychosocial barriers associated with the use/non-use of reproductive health (RH) services. The sample included 212 college students (60 % female) aged 18-19 from a Northern California public university. In October, 2014, students took an on-line survey with questions on knowledge, access, barriers, and use of different RH services and settings. Findings indicated that college students were more likely to visit a primary care setting and/or school-based setting for their RH care. Sexual intercourse was the strongest correlate of having received RH care in the past year, followed by gender, social disapproval, and knowledge of available services. Analyses stratified by gender found a similar pattern among females. However, the only significant predictor among males was knowledge of available services. These finding highlight universities as uniquely positioned to reduce perceived barriers to accessing RH services by making use of technology, promoting health and wellness centers, and providing/adding sexual and reproductive information to general education classes.
