Wide Variability in Dysplasia Detection Rate and Adherence to Seattle Protocol and Surveillance Recommendations in Barrett's Esophagus: A Population-Based Analysis Using the GIQuIC National Quality Benchmarking Registry.

INTRODUCTION: Variability in adherence rates to the Seattle protocol and to surveillance interval recommendations, established quality indicators (QIs) in Barrett's esophagus (BE), is unknown. METHODS: We evaluated endoscopist and site-based adherence rates to these QIs from January 2018 to May 2021 using the GI Quality Improvement Consortium national registry with matched endoscopy and pathology data. RESULTS: Across 153 practices with 572 endoscopists performing 20,155 endoscopies, adherence to the Seattle protocol varied by endoscopists (median 93.8%, IQR 18.9%) and by site (median 90.0%, IQR 20.1%). Adherence to appropriate surveillance intervals for nondysplastic BE also varied by endoscopist (median 82.4%, IQR 36.3%) and site (median 77.2%, IQR 29.8%). The overall dysplasia detection rate was 3.1% and varied among endoscopists and sites. DISCUSSION: These US population-based results can serve as a benchmark for quality initiatives and intervention trials aimed at improving outcomes for patients with BE.

Patient Knowledge, Risk Perception, and Barriers to Barrett's Esophagus Screening.

INTRODUCTION: Most patients with esophageal adenocarcinoma (EAC) do not have a previous diagnosis of Barrett's esophagus (BE), demonstrating a failure of current screening practices. An understanding of patient attitudes and barriers is essential to develop and implement interventions to improve BE screening adherence. METHODS: We conducted a Web-based survey of patients aged >50 years with chronic gastroesophageal reflux disease at 3 academic medical centers and 1 affiliated safety net health systems. Survey domains included patient characteristics, endoscopy history, familiarity with screening practices, perceived BE/EAC risk, and barriers to screening. RESULTS: We obtained a response rate of 22.6% (472/2,084) (74% men, mean age 67.9 years). Self-identified race and ethnicity of participants was 66.5% non-Hispanic White, 20.0% non-Hispanic Black, 13.4% other race, and 7.1% Hispanic. Screening for BE was recommended in only 13.2%, and only 5.3% reported previous screening. Respondents had notable gaps in knowledge about screening indications; only two-thirds correctly identified BE risk factors and only 19.5% believed BE screening was needed for gastroesophageal reflux disease. More than 1 in 5 respondents believed they would get BE (31.9%) or EAC (20.2%) but reported barriers to screening. Compared with White respondents, more Black respondents were concerned about getting BE/EAC and interested in screening but report higher barriers to screening. DISCUSSION: Patients at risk for BE, particularly racial and ethnic minorities, are worried about developing EAC but rarely undergo screening and have poor understanding of screening recommendations.

Dutch, UK and US professionals' perceptions of screening for Barrett's esophagus and esophageal adenocarcinoma: a concept mapping study.

BACKGROUND: Novel, less-invasive technologies to screen for Barrett's esophagus (BE) may enable a paradigm shift in early detection strategies for esophageal adenocarcinoma (EAC). Understanding professionals' perspectives on screening is important to determine how to proceed. We aimed to explore and compare professionals' perceptions of screening for BE and EAC screening in three countries. METHODS: In this study, 29 Dutch, 20 British and 18 American health care professionals (clinicians, researchers and policy makers) participated in concept mapping: a mixed-methods consensus building methodology. Statements on perceived barriers, facilitators, advantages, disadvantages, implications or worries associated with screening for BE and EAC were collected in asynchronous digital brainstorm sessions. Subsequently, participants sorted the statements into groups according to thematic similarity and assessed the relevance of each statement in evaluating the acceptability of BE and EAC screening. Multidimensional scaling and cluster analysis were used to map the associations between generated statements. RESULTS: Professionals across three countries identified eight consistent themes that relate to their perceptions of screening for BE and EAC: (1) Benefits, (2) Harms, (3) Clinical effectiveness concerns, (4) Screening population, (5) Screening modality, (6) Resources, (7) Ownership, and (8) Public communication. Dutch and American professionals prioritized the potential health benefits of screening but also questioned clinical impact. In contrast, British participants prioritized identification of the screening population and suitable test. CONCLUSIONS: Most professionals see potential in less-invasive screening tests for BE and EAC but underline the need to define the target screening population and determine benefits and harms before widely employing them. Successful implementation will require thoughtful consideration of the involvement of general practitioners, readiness of endoscopy and pathology services, balanced public communication, and country-specific regulations.

The status of endoscopic therapies for gastroesophageal reflux disease.

PURPOSE OF REVIEW: Gastroesophageal reflux disease (GERD) is exceedingly common and can significantly impact quality of life through heartburn, troublesome regurgitation, or atypical symptoms. The initial approach is conservative lifestyle changes followed by medications with escalation to antireflux surgery as needed. Endoscopic therapy may represent a bridge between pharmacotherapy and surgery and represents an appropriate option for select individuals. RECENT FINDINGS: Appropriate patient selection for endoscopic antireflux therapies is critical to the success of the intervention. Candidates for endoscopic treatment with trans-oral incisionless fundoplication (TIF) include those with a small (<2 cm) or no hiatal hernia and a Hill valve grade 1 or 2. Transoral incisionless fundoplication with concomitant hiatal hernia repair (cTIF) is a safe and effective option that addresses both the crural diaphragm and gastroesophageal flap valve (GEFV). SUMMARY: Endoscopic interventions for GERD continue to evolve and are not all created equal. Given our current understanding of the mechanisms of GERD, the TIF procedure stands out in its ability to re-create the optimal GEFV. In those patients with altered anatomy, endoscopic approaches may offer at least partial benefit.

Structured training program on confocal laser endomicroscopy for pancreatic cystic lesions: a multicenter prospective study among early-career endosonographers (with video).

BACKGROUND AND AIMS: Data on how to teach endosonographers needle-based confocal laser endomicroscopy (nCLE)-guided histologic diagnosis of pancreatic cystic lesions (PCLs) are limited. Hence, we developed and tested a structured educational program to train early-career endosonographers in nCLE-guided diagnosis of PCLs. METHODS: Twenty-one early-career nCLE-naïve endosonographers watched a teaching module outlining nCLE criteria for diagnosing PCLs. Participants then reviewed 80 high-yield nCLE videos, recorded diagnoses, and received expert feedback (phase 1). Observers were then randomized to a refresher feedback session or self-learning at 4 weeks. Eight weeks after training, participants independently assessed the same 80 nCLE videos without feedback and provided histologic predictions (phase 2). Diagnostic performance of nCLE to differentiate mucinous versus nonmucinous PCLs and to diagnose specific subtypes were analyzed using histopathology as the criterion standard. Learning curves were determined using cumulative sum analysis. RESULTS: Accuracy and diagnostic confidence for differentiating mucinous versus nonmucinous PCLs improved as endosonographers progressed through nCLE videos in phase 1 (P < .001). Similar trends were observed with the diagnosis of PCL subtypes. Most participants achieved competency interpreting nCLE, requiring a median of 38 assessments (range, 9-67). During phase 2, participants independently differentiated PCLs with high accuracy (89%), high confidence (83%), and substantial interobserver agreement (κ = .63). Accuracy for nCLE-guided PCL subtype diagnoses ranged from 82% to 96%. The learned nCLE skills did not deteriorate at 8 weeks and were not impacted by a refresher session. CONCLUSIONS: We developed a practical, effective, and durable educational intervention to train early-career endosonographers in nCLE-guided diagnosis of PCLs.

Role of short interval FLIP panometry in predicting long-term outcomes after per-oral endoscopic myotomy.

BACKGROUND: The Eckardt score (ES) is used to assess symptom response to Per-Oral Endoscopic Myotomy (POEM), but reliable methods to assess physiologic success are needed. Functional lumen imaging probe (FLIP) panometry has a potential role in post-POEM follow-up to predict long-term outcomes. The aim of this study was to assess the correlation between clinical success and FLIP parameters following POEM to determine if short interval FLIP could predict long-term outcomes. METHODS: This was a prospective study of adult patients who underwent POEM with short interval follow-up FLIP between 11/2017 and 3/2020. Clinical success was defined as post-procedure ES ≤ 3. Physiologic success was based on an esophago-gastric junction distensibility index (EGJ-DI) > 2.8 mm2/mmHg on FLIP. RESULTS: 47 patients (55% female, mean age 55 years) were included in the study. Clinical success after POEM was seen in 45 (96%) patients (mean ES 6.5 ± 2.2 pre and 0.83 ± 1.0 post-POEM, p < 0.001). Physiologic success was noted in 43 (91.5%) patients (mean EGJ-DI 6.1 mm2/mmHg ± 2.5). Among 4 patients not meeting criteria for physiologic success, EGJ-DI was 2.5-2.6. There was no correlation between post-POEM EGJ-DI and ES in the short term or long term. Significant reflux esophagitis was seen in 6 (12.8%) patients with no difference in mean EGJ-DI with vs without esophagitis (5.9 vs 6.1, p = 0.44). CONCLUSION: Post-POEM endoscopy with FLIP is useful to both assess EGJ physiology and to examine for reflux esophagitis. Short interval FLIP has limited utility to predict long-term patient outcomes or risk of acid reflux.

Histology, Size, and Number of Advanced Polyps are Associated With Guideline-Discordant Surveillance Recommendations.

Surveillance guidelines following polypectomy promote cost-effective reductions in future colorectal cancer (CRC) risk, but high nonadherence rates1 can have negative consequences on costs and effectiveness. Professional societies recommend a 3-year interval for patients with advanced colorectal polyps (ACPs), although few studies report provider adherence to surveillance intervals.2 This study evaluated rates and predictors of guideline-discordant recommendations for patients with ACPs.

Early-Age Onset Colorectal Neoplasia in Average-Risk Individuals Undergoing Screening Colonoscopy: A Systematic Review and Meta-Analysis.

BACKGROUND & AIMS: Incidence and mortality associated with early-age onset colorectal cancer (EAO-CRC) is increasing, prompting professional society recommendations to lower the screening age in average-risk individuals. The yield of screening individuals younger than 50 years is not known. METHODS: A systematic review of 3 databases from inception through July 2020 was performed in all languages that reported colonoscopy findings in average-risk individuals younger than 50 years. The primary outcomes were EAO colorectal neoplasia (CRN) and advanced colorectal neoplasia (aCRN) prevalence. Subgroup analyses were performed based on sex, geographic location, time period, and age, including comparison with those aged 50-59 years. Generalized linear mixed model with random intercept logistic regression and fixed subgroup effects were performed. RESULTS: Of 10,123 unique articles, 17 studies published between 2002 and 2020, including 51,811 average-risk individuals from 4 continents, were included. The pooled rate of EAO-CRN was 13.7% (95% confidence interval [CI], 0.112%-0.168%) and EAO-aCRN was 2.2% (95% CI, 0.016%-0.031%). Prevalence of CRC was 0.05% (95% CI, 0.00029%-0.0008%). Rates of EAO-CRN were higher in men compared with women (relative risk, 1.71%; 95% CI, 1.49%-1.98%), and highest in the United States (15.6%; 95% CI, 12.2%-19.7%) compared with Europe (14.9%; 95% CI, 6.9%-29.3%), East Asia (13.4%; 95% CI, 10.3%-17.2%), and the Middle East (9.8%; 95% CI, 7.8%-12.2%) (P = .04) The rate of EAO-CRN in age groups 45-49 years and 50-59 years was 17.8% (95% CI, 14.5%-21.6%) and 24.8% (95% CI, 19.5%-30.8%), respectively (P = .04). The rate of EAO-aCRN in age group 45-49 years was 3.6% (95% CI, 1.9%-6.7%) and 4.2% (95% CI, 3.2%-5.7%), respectively (P = .69). CONCLUSIONS: The rate of aCRN in individuals aged 45-49 years was similar to the rate observed in individual aged 50-59 years, suggesting that expanding screening to this population could yield a similar impact on colorectal cancer risk reduction.

Characterization of Prevalent, Post-Endoscopy, and Incident Esophageal Cancer in the United States: A Large Retrospective Cohort Study.

BACKGROUND & AIMS: Efforts to assess and improve the effectiveness of Barrett's esophagus (BE) screening and surveillance are ongoing in the United States. Currently, there are limited population-based data in the United States to guide these efforts. METHODS: We performed a retrospective cohort study using data from large commercial and Medicare Advantage health plans in the United States from 2004 - 2019. We identified individuals with BE and analyzed the proportion who developed EAC. EACs were classified as prevalent EAC (diagnosed within 30 days of index endoscopy), post-endoscopy esophageal adenocarcinoma (PEEC, diagnosed 30 - 365 days after index endoscopy), and incident EAC (diagnosed 365 days or more after index endoscopy). Using this cohort, we performed a nested case-control study to identify factors associated with prevalent EAC at BE diagnosis and study healthcare utilization prior to BE diagnosis. RESULTS: We identified 50,817 individuals with incident BE. Of the 366 who developed EAC, 67.2%, 13.7%, and 19.1% were diagnosed with prevalent EAC, PEEC, and incident EAC respectively. Factors positively associated with prevalent EAC versus BE without prevalent EAC included male sex, dysphagia, weight loss, and Charlson-Deyo comorbidity score. In those with prevalent EAC, most patients with dysphagia or weight loss had their symptoms first recorded within three months of EAC diagnosis. Healthcare utilization rates were similar between those with and without prevalent EAC. CONCLUSIONS: Two-thirds of EACs among individuals with BE are diagnosed at the time of BE diagnosis. Additionally, PEEC accounts for 14% of these EACs. These results may guide future research studies that investigate novel BE diagnostic strategies that reduce the morbidity and mortality of EAC.

Magnitude and Time-Trend Analysis of Postendoscopy Esophageal Adenocarcinoma: A Systematic Review and Meta-analysis.

BACKGROUND & AIMS: Identification of postendoscopy esophageal adenocarcinoma (PEEC) among Barrett's esophagus (BE) patients presents an opportunity to improve survival of esophageal adenocarcinoma (EAC). We aimed to estimate the proportion of PEEC within the first year after BE diagnosis. METHODS: Multiple databases (Medline, Embase, Scopus, and Cochrane databases) were searched until September 2020 for original studies with at least 1-year follow-up evaluation that reported EAC and/or high-grade dysplasia (HGD) in the first year after index endoscopy in nondysplastic BE, low-grade dysplasia, or indefinite dysplasia. The proportions of PEEC defined using EAC alone and EAC+HGD were calculated by dividing EAC or EAC+HGD in the first year over the total number of EAC or EAC+HGD, respectively. RESULTS: We included 52 studies with 145,726 patients and a median follow-up period of 4.8 years. The proportion of PEEC (EAC) was 21% (95% CI, 13-31) and PEEC (EAC+HGD) was 26% (95% CI, 19-34). Among studies with nondysplastic BE only, the PEEC (EAC) proportion was 17% (95% CI, 11-23) and PEEC (EAC+HGD) was 14% (95% CI, 8-19). Among studies with 5 or more years of follow-up evaluation, the PEEC (EAC) proportion was 10% and PEEC (EAC+HGD) was 19%. Meta-regression analysis showed a strong inverse relationship between PEEC and incident EAC (P < .001). The PEEC (EAC) proportion increased from 5% in studies published before 2000 to 30% after 2015. Substantial heterogeneity was observed for most analyses. CONCLUSIONS: PEEC accounts for a high proportion of HGD/EACs and is proportional to reduction in incident EAC. Using best endoscopic techniques now and performing future research on improving neoplasia detection through implementation of quality measures and educational tools is needed to reduce PEEC.

Endoscopic ultrasound-guided portal pressure gradient with liver biopsy: 6 years of endo-hepatology in practice.

BACKGROUND AND AIM: The portal pressure gradient (PPG) is a useful predictor of portal hypertension (PH) related complications. We previously showed the feasibility and safety of endoscopic ultrasound guided PPG measurement (EUS-PPG). Now EUS-guided liver biopsy (EUS-bx) has been shown to be a safe and effective alternative to percutaneous or Interventional Radiology-guided liver biopsy for the diagnosis of chronic liver disease (CLD). We aimed to evaluate the correlation between PPG and clinical markers of PH, and assess the feasibility and safety of concomitant, single session EUS-PPG and EUS-bx. METHODS: This was a retrospective study of patients undergoing EUS-PPG for CLD at a single tertiary endoscopy center between February 2014 and March 2020. EUS-PPG was performed using a 25-gauge needle and compact manometer. Data analysis was performed with SAS version 9.4. RESULTS: Eighty-three patients underwent EUS-PPG with 100% technical success. The mean PPG was 7.06 mmHg (SD 6.09, range 0-27.3). PPG was higher in patients with (vs without) clinical features of cirrhosis (9.46 vs 3.61 mmHg, P < 0.0001), esophageal or gastric varices (13.88 vs 4.34 mmHg, P < 0.0001), and thrombocytopenia (9.25 vs 4.71 mmHg, P = 0.0022). In the 71 patients (85.5%) who underwent EUS-bx, 70 (98.6%) specimens were deemed adequate by the pathologist for histologic diagnosis. There were no early or late major adverse events. CONCLUSION: EUS-PPG correlates well with clinical markers of PH. EUS-bx can be performed safely during the same session as EUS-PPG, providing a comprehensive endoscopic evaluation of the patient with CLD.

Digestive Manifestations in Patients Hospitalized With Coronavirus Disease 2019.

BACKGROUND & AIMS: The prevalence and significance of digestive manifestations in coronavirus disease 2019 (COVID-19) remain uncertain. We aimed to assess the prevalence, spectrum, severity, and significance of digestive manifestations in patients hospitalized with COVID-19. METHODS: Consecutive patients hospitalized with COVID-19 were identified across a geographically diverse alliance of medical centers in North America. Data pertaining to baseline characteristics, symptomatology, laboratory assessment, imaging, and endoscopic findings from the time of symptom onset until discharge or death were abstracted manually from electronic health records to characterize the prevalence, spectrum, and severity of digestive manifestations. Regression analyses were performed to evaluate the association between digestive manifestations and severe outcomes related to COVID-19. RESULTS: A total of 1992 patients across 36 centers met eligibility criteria and were included. Overall, 53% of patients experienced at least 1 gastrointestinal symptom at any time during their illness, most commonly diarrhea (34%), nausea (27%), vomiting (16%), and abdominal pain (11%). In 74% of cases, gastrointestinal symptoms were judged to be mild. In total, 35% of patients developed an abnormal alanine aminotransferase or total bilirubin level; these were increased to less than 5 times the upper limit of normal in 77% of cases. After adjusting for potential confounders, the presence of gastrointestinal symptoms at any time (odds ratio, 0.93; 95% CI, 0.76-1.15) or liver test abnormalities on admission (odds ratio, 1.31; 95% CI, 0.80-2.12) were not associated independently with mechanical ventilation or death. CONCLUSIONS: Among patients hospitalized with COVID-19, gastrointestinal symptoms and liver test abnormalities were common, but the majority were mild and their presence was not associated with a more severe clinical course.

The Volume-Outcome Effect Calls for Centralization of Care in Esophageal Adenocarcinoma: Results From a Large National Cancer Registry.

INTRODUCTION: Using the National Cancer Database, we assessed the relationship between facility overall esophageal adenocarcinoma (EAC) case volume and survival. METHODS: We categorized facilities into volume quintiles based on annual EAC patient volume and performed a multivariable Cox proportional hazards regression between facility patient volume and survival. RESULTS: In a cohort of 116,675 patients, facilities with higher vs lower (≥25 vs 1-4 cases) annual EAC patient volume demonstrated improved survival (adjusted hazard ratio: 0.80. 95% confidence interval: 0.70-0.91). DISCUSSION: This robust volume-outcome effect calls for centralization of care for EAC patients at high annual case volume facilities.

Survey Finds Gender Disparities Impact Both Women Mentors and Mentees in Gastroenterology.

INTRODUCTION: Gastroenterologists at all levels of practice benefit from formal mentoring. Much of the current literature on mentoring in gastroenterology is based on expert opinion rather than data. In this study, we aimed to identify gender-related barriers to successful mentoring relationships from the mentor and mentee perspectives. METHODS: A voluntary, web-based survey was distributed to physicians at 20 academic institutions across the United States. Overall, 796 gastroenterology fellows and faculty received the survey link, with 334 physicians responding to the survey (42% response rate), of whom 299 (90%; 129 women and 170 men) completed mentorship questions and were included in analysis. RESULTS: Responses of women and men were compared. Compared with men, more women preferred a mentor of the same gender (38.6% women vs 4.2% men, P < 0.0001) but less often had one (45.5% vs 70.2%, P < 0.0001). Women also reported having more difficulty finding a mentor (44.4% vs 16.0%, P < 0.0001) and more often cited inability to identify a mentor of the same gender as a contributing factor (12.8% vs 0.9%, P = 0.0004). More women mentors felt comfortable advising women mentees about work-life balance (88.3% vs 63.8%, P = 0.0005). Nonetheless, fewer women considered themselves effective mentors (33.3% vs 52.6%, P = 0.03). More women reported feeling pressured to mentor because of their gender (39.5% vs 0.9% of men, P < 0.0001). Despite no gender differences, one-third of respondents reported negative impact of the COVID-19 pandemic on their ability to mentor and be mentored. DISCUSSION: Inequities exist in the experiences of women mentees and mentors in gastroenterology, which may affect career advancement and job satisfaction.

[Social Inequalities in Health and Health Behaviors among University Students]. / Sozialbedingte Ungleichheiten von Gesundheit und Gesundheitsverhalten bei Studierenden.

AIM OF THE STUDY: Disease prevention and health science research have focused increasingly on students in recent years. However, students are usually perceived as a homogeneous group. The aim of this article was to examine if there exist health inequalities among students. METHODS: A nationwide student survey, the so-called NuPhA study, was used to answer this question (n=689, 69.5% female, average age: 22.69 years). RESULTS AND CONCLUSIONS: We found that socio-economic indicators were associated with health and health behavior. For instance, being a scholarship holder was associated with a better general, mental, and physical health. In particular, subjective social status was positively associated with better general, mental, and physical health as well as higher physical activity. The results indicate that while students initially appeared to form a homogenous group, health inequalities exist among them. This suggests the need for a differentiated view on the student group and the importance of examining and explaining health inequalities among students in depth and to finally reduce them.

Increased Risk of Colorectal Cancer Tied to Advanced Colorectal Polyps: An Untapped Opportunity to Screen First-Degree Relatives and Decrease Cancer Burden.

Advanced adenomas represent a subset of colorectal polyps that are known to confer an increased risk of colorectal neoplasia to the affected individual and their first-degree relatives (FDRs). Accordingly, professional guidelines suggest earlier and more intensive screening for FDRs of those with advanced adenomas similar to FDRs of those with colorectal cancer (CRC). Although the risk to family members is less clear among patients with advanced serrated polyps, they are often considered in the same category. Unfortunately, there is a growing concern that patients, endoscopists, and primary care providers are unaware of the familial risk associated with these polyps, leaving a wide gap in screening these high-risk individuals. Herein, we propose a standardized language around advanced colorectal polyps and present a detailed review of the literature on associated familial risk. We outline the challenges to implementing the current screening recommendations and suggest approaches to overcome these limitations, including a proposed new colonoscopy quality metric to capture communication of familial CRC risk. Improving screening in these high-risk groups has the potential to substantially reduce the burden of CRC.

Endoscopic eradication therapy for Barrett's oesophagus: state of the art.

PURPOSE OF REVIEW: Barrett's oesophagus is the only identifiable precursor lesion to oesophageal adenocarcinoma. The stepwise progression of Barrett's oesophagus to dysplasia and invasive carcinoma provides the opportunity to intervene and reduce the morbidity and mortality associated with this lethal cancer. Several studies have demonstrated the efficacy and safety of endoscopic eradication therapy (EET) for the management of Barrett's oesophagus related neoplasia. The primary goal of EET is to achieve complete eradication of intestinal metaplasia (CE-IM) followed by enrolment of patients in surveillance protocols to detect recurrence of Barrett's oesophagus and Barrett's oesophagus related neoplasia. RECENT FINDINGS: EET depends on early and accurate detection and diagnosis of Barrett's oesophagus related neoplasia. All visible lesions should be resected followed by ablation of the remaining Barrett's epithelium. After treatment, patients should be enrolled in endoscopic surveillance programmes. For nondysplastic Barrett's oesophagus, surveillance alone is recommended. For low-grade dysplasia, both surveillance and ablation are reasonable options and should be decided on an individual basis according to patient risk factors and preferences. EET is preferred for high-grade dysplasia and intramucosal carcinoma. For T1b oesophageal adenocarcinoma, esophagectomy remains the standard of care, but endoscopic therapy can be considered in select cases. SUMMARY: EET is now standard of care and endorsed by societal guidelines for the treatment of Barrett's oesophagus related neoplasia. Future studies should focus on risk stratification models using a combination of clinical data and biomarkers to identify ideal candidates for EET, and to predict recurrence. Optimal therapy for T1b cancer and surveillance strategy after CE-IM are topics that require further study.

Obesity à la carte? Children's meal options in German full-service restaurants.

OBJECTIVE: In light of the increasing prevalence of juvenile obesity seen around the world, obesogenic environments in general and the food environment in particular are receiving increasing attention in current public health research. Restaurants play a significant role in the food environment. The present study aimed to quantitatively describe and qualitatively evaluate the range of children's meals available in full-service restaurants in Germany. DESIGN: Five hundred restaurants were identified using a systematic quota sampling technique. The individual meals were evaluated using quality standards stipulated by the German Nutrition Society (DGE). SETTING: Nationwide sample of menus from full-service restaurants. PARTICIPANTS: Meals (n 1877) from 500 menus were analysed. RESULTS: Menus included 3·76 (sd 1·31) meals for children. About 70 % of the meals were limited to six typical dishes of low nutritional quality. In total, 54 % of meals included French fries or another form of fried potatoes. Of all meals, 23 % did not fulfil any of the eleven quality criteria set by the DGE and 38 % satisfied only one criterion. The majority of dishes on offer featured high energy density while simultaneously having low nutrient density. Healthy dishes were not highlighted visually in any menu. CONCLUSIONS: The range of dishes on offer for children in German restaurants is severely lacking in variety and in need of improvement from a nutritional point of view. Considering the growing importance of restaurants as food environments, there is a need to improve the presentation of menus and the meals offered.

'When I have time pressure, sport is the first thing that is cancelled': A mixed-methods study on barriers to physical activity among university students in Germany.

The transition from school to university has been found to be associated with a decline in physical activity (PA). As regular engagement in PA plays an important role in preventing obesity and various chronic diseases such as type 2 diabetes and cardiovascular diseases, a deeper understanding on barriers that hinder university students from being physically active is necessary. We therefore conducted a mixed-methods study which built, first, on conducting a quantitative online survey across Germany (n = 689; 69.5% female) to examine barriers among university students. Afterwards, we explored these barriers in more detail by conducting 20 in-depth qualitative interviews (65.0% female). While we identified in our quantitative survey that especially time-related and motivational barriers hindered university students to engage in PA, our qualitative interviews indicate that connections between these barriers seem to exist. Moreover, the qualitative interviews enabled us to identify additional transition-related barriers (e.g., missing routines in everyday life, difficulties in finding a new sports club) that were not included in the quantitative questionnaire. Thus, such barriers should be incorporated into quantitative instruments to assess these barriers in larger samples of university students in the future. Moreover, our findings provide potential starting points for promoting PA in German university settings.

Desert on the menu? What children are served in German full-service restaurants.

OBJECTIVES: Prevalence of obesity and overweight among children is rising worldwide. Thus, the importance of restaurants as food environments is also growing. Considering these developments, the present study describes and evaluates menus and meals offered to children in German full-service restaurants. METHODS: Using quota sampling procedure, a representative sample of German full-service restaurants was identified. The individual meals were then assessed, using the Children's Menu Assessment tool (CMA). A total of 500 restaurants and 1,877 individual meals were analyzed. RESULTS: On average, every menu included 3.76 ± 1.31 meals for children. The arithmetic mean of the CMA score was 0.73 ± 0.85. Around 80% of all offered meals were limited to eight typical dishes and over 50% included French fries or another form of fried potatoes. Not one of the meals included any nutritional information. Healthy entrees were never marked (e.g. by an optional qualitative information such as healthy food symbol or a healthier choice tag). Eighty-one percent of all the main components in the meals were rated as unhealthy and none of the meals used wholegrain products. The automatic inclusion of a drink and free refill options are both rather unusual in Germany, as well as the use of cartoon characters and product logos or giving away promotional toys. A positive correlation was found between the price of the food and its quality. The majority of dishes feature a high energy density while simultaneously having a low nutrient density. CONCLUSIONS: Overall, the range of food on offer for children in German restaurants is unhealthy and lacking in variety. There is an urgent need for improvement of both the menus themselves as well as the offered meals. Our study is not only by far the most comprehensive study, but also the study with the worst CMA score values worldwide.
