Sleep Disturbance as a Mediator of Lung Cancer Stigma on Psychological Distress and Physical Symptom Burden.

OBJECTIVE: This study tested sleep disturbance as a mediator through which stigma and discrimination predict psychological distress and physical symptom burden in adults with lung cancer. METHODS: Lung cancer patients on active oncological treatment ( N = 108; 74.1% stage IV) completed questionnaires on lung cancer stigma, sleep, distress, and physical symptoms at study entry and at 6- and 12-week follow-up. Mediation analyses were conducted to investigate whether stigma and discrimination predicted distress and physical symptoms at study entry and across 12 weeks through disrupted sleep. RESULTS: Higher discrimination ( b = 5.52, 95% confidence interval [CI] = 2.10-8.94) and constrained disclosure ( b = 0.45, 95% CI = 0.05-0.85) were associated significantly with higher sleep disruption at study entry. Sleep disruption, in turn, was associated with higher distress ( b = 0.19, 95% CI = 0.09-0.29) and physical symptoms ( b = 0.28, 95% CI = 0.17-0.40) at study entry. Sleep disruption significantly mediated relationships between higher discrimination and the outcomes of distress (indirect effect = 1.04, 95% CI = 0.13-1.96) and physical symptoms (indirect effect = 1.58, 95% CI = 0.37-2.79) at study entry. Sleep disruption also mediated relationships between constrained disclosure and the outcomes of distress (indirect effect = 0.85, 95% CI = < 0.01-0.17) and physical symptoms (indirect effect = 0.13, 95% CI = 0.01-0.25). CONCLUSIONS: Lung cancer patients evidenced pronounced sleep disruption, which mediated relationships between indicators of lung cancer stigma and distress and physical symptoms at study entry. Research is needed to test additional mechanisms through which lung cancer stigma predicts these outcomes longitudinally.

Correlation of the Endoscopic Gastroesophageal Flap Valve with Pathologic Reflux.

BACKGROUND: The Hill classification characterizes the geometry of gastroesophageal junction and Hill grades (HGs) III and IV have a high association with pathologic reflux. This study aimed to understand the use of the Hill classification and correlate the prevalence of pathologic reflux across different HGs. STUDY DESIGN: A retrospective review of 477 patients who underwent upper endoscopy and BRAVO pH monitoring between August 2018 and October 2021 was performed. These charts were reviewed for endoscopic findings for hiatal hernia and association of HGs with pathologic reflux, defined as an abnormal esophageal acid exposure time (AET) of ≥4.9%. RESULTS: Of 477 patients, 252 (52.8%) had an HG documented on the endoscopy report. Of the 252 patients, 61 had HG I (24.2%), 100 had HG II (39.7%), 61 had HG III (24.2%), and 30 had HG IV (11.9%). The proportion of patients with abnormal AET increases with increasing HGs (p < 0.001) as follows: I (39.3%), II (52.5%), III (67.2%), and IV (79.3%). The mean overall AET is as follows: HG I (5.5 ± 6%), HG II (7.0 ± 5.9%), HG III (10.2 ± 10.3%), and HG IV (9.5 ± 5.5%). The proportion of patients with hiatal hernia was 18% for HG I, 28% for HG II, 39.3% for HG III, and 80% for HG IV. CONCLUSIONS: Use of the Hill classification in clinical practice is low. There is an association of increasing HGs with increasing proportion of patients with abnormal AET. There is a high proportion of patients within HGs I and II with documented pathologic reflux and the presence of a hiatal hernia as observed on endoscopic examination. Our study suggests that endoscopic grading of the gastroesophageal junction may not adequately differentiate between normal vs abnormal reflux status, particularly for HGs I and II.

Moderators of Loneliness Trajectories in People with Systemic Sclerosis During the COVID-19 Pandemic: A SPIN COVID-19 Cohort Longitudinal Study.

BACKGROUND: Many individuals with systemic sclerosis (SSc) are at heightened risk for COVID-19 related morbidity and isolation due to interstitial lung disease, frailty, and immunosuppressant use. Minimal research has explored loneliness predictors in individuals with chronic illnesses during COVID-19. This study evaluated moderators of loneliness trajectories in individuals with SSc during COVID-19. METHODS: Longitudinal data were analyzed across 30 timepoints from April 2020 to May 2022 from 775 adults in the Scleroderma Patient-centered Intervention Network (SPIN) COVID-19 Cohort. Hierarchical linear modeling evaluated cross-level moderators of loneliness trajectories, including marital status, baseline number of household members, number of virtual or telephone one-on-one or virtual group conversations, number of hours spent enjoying in-person household conversations or activities, and satisfaction with quality of in-person household conversations (all in the past week). Level-1 moderation analyses assessed effects of conversation, activity, and satisfaction means and slopes over time. RESULTS: Baseline values were not statistically significant moderators of loneliness trajectories. Higher mean (averaged over time) virtual or telephone one-on-one and in-person household conversations, in-person household activity, and in-person household conversation satisfaction were associated with lower loneliness trajectories (ps < .05). The relationship between in-person household conversation satisfaction and loneliness trajectory was statistically significantly but minimally attenuated over time (p < .001). CONCLUSIONS: For people with SSc, higher mean conversation, activity, and satisfaction variables were associated with lower levels of loneliness during the pandemic, but changes in these social variables were generally not predictive of changes in loneliness.

Measurement equivalence of the English and French versions of the self-efficacy to manage chronic disease scale: a Scleroderma Patient-Centered Intervention Network (SPIN) study.

PURPOSE: The Self-Efficacy to Manage Chronic Disease (SEMCD) scale is widely used, including in systemic sclerosis (SSc). The SEMCD has been validated in SSc, but the metric equivalence of the English and French versions has not been assessed (i.e., whether psychometric properties are equivalent across English and French). METHODS: Participants were adults from the Scleroderma Patient-Centered Intervention Network (SPIN) Cohort (N = 2159) who completed baseline measures in English (n = 1473) or French (n = 686) between May 2014 to July 2020. Analyses assessed internal consistency reliability via Cronbach's alpha and McDonald's omega, convergent validity via Pearson's correlations, structural validity via confirmatory factor analysis (CFA), and differential item functioning via the Multiple-Indicator Multiple-Cause (MIMIC) model. RESULTS: Internal consistency reliability was high in English (α = .93, ω = .93) and French (α = .92, ω = .93). All correlations between the SEMCD and measures of health outcomes were moderate to large, statistically significant, and in the hypothesized direction in both languages. The CFA demonstrated that the one-factor model of self-efficacy, overall, fit reasonably well (CFI = .96, TLI = .93, SRMR = .03, RMSEA = .14). Standardized factor loadings were large (.76 to .88). Three items displayed statistically significant uniform DIF and all six displayed nonuniform DIF; all DIF was of minimal magnitude. Comparison of unadjusted and DIF-adjusted models indicated that DIF did not meaningfully impact total score (ICC = 0.999, r = 0.999). CONCLUSION: Scores from English- and French-speaking adults with SSc can be combined for analysis or compared.

Visual cues and food intake: A preregistered replication of Wansink et al. (2005).

Imagine a bowl of soup that never emptied, no matter how many spoonfuls you ate-when and how would you know to stop eating? Satiation can play a role in regulating eating behavior, but research suggests visual cues may be just as important. In a seminal study by Wansink et al. (2005), researchers used self-refilling bowls to assess how visual cues of portion size would influence intake. The study found that participants who unknowingly ate from self-refilling bowls ate more soup than did participants eating from normal (not self-refilling) bowls. Despite consuming 73% more soup, however, participants in the self-refilling condition did not believe they had consumed more soup, nor did they perceive themselves as more satiated than did participants eating from normal bowls. Given recent concerns regarding the validity of research from the Wansink lab, we conducted a preregistered direct replication study of Wansink et al. (2005) with a more highly powered sample (N = 464 vs. 54 in the original study). We found that most results replicated, albeit with half the effect size (d = 0.45 instead of 0.84), with participants in the self-refilling bowl condition eating significantly more soup than those in the control condition. Like the original study, participants in the self-refilling condition did not believe they had consumed any more soup than participants in the control condition. These results suggest that eating can be strongly controlled by visual cues, which can even override satiation. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Performance of Endoscopic Ultrasound-Guided Versus Percutaneous Liver Biopsy in Diagnosing Stage 3-4 Fibrosis.

BACKGROUND: Percutaneous liver biopsy (P-bx) is the gold standard for diagnosing advanced fibrosis. Despite the proven technical feasibility of EUS-guided liver bx (EUS-bx) as a novel alternative way of liver biopsy, the clinical applicability remains to be determined. AIMS: The primary aim of this study is to evaluate if EUS-bx, compared to P-bx, can effectively and safely obtain adequate specimen and accurately predict hepatic fibrosis. METHODS: This is a single center, retrospective chart review among patients with liver diseases at a tertiary endoscopy center from February 2011 to March 2020. We assessed the EUS-bx versus P-bx outcomes by success rate, performance, and safety profile. The primary outcome was the association between EUS-bx clinical variables and the presence of histologic liver fibrosis stage ≥ 3. The secondary outcomes were the associations between EUS-bx and variables indicative of fibrosis. RESULTS: Fifty-nine patients underwent EUS-bx; and 59, P-bx. All EUS-bx procedures were successfully completed. All 56/56 (100%) of EUS-bx vs. 50/52 (96.2%) P-bx were considered adequate samples. Tissue lengths were significantly longer in the EUS-bx cohort (p < 0.0001) with a trend towards a greater number of portal tracts. 46/56 (82.1%) cases of EUS-bx vs. 32/52 (61.5%) of P-bx had > 10 portal tracts; 21/56 (37.5%) cases of EUS-bx vs. 14/52 (26.9%) of P-bx had > 15 portal tracts. There were 6 (10.2%) EUS-bx vs. 1 (1.7%) P-bx related complication leading to a phone call (p = 0.061). CONCLUSIONS: EUS-bx can safely performed and accurately predict liver fibrosis stage as the standard P-bx without being influenced by procedure-related factors.

To Operate or Not to Operate? Reconstructive Surgical Burden and Quality of Life of Pediatric Patients with Facial Differences.

OBJECTIVE: The Craniofacial Condition Quality of Life Scale (CFC-QoL) was used to evaluate the relationship between surgical burden and quality of life (QoL). DESIGN: Patient-parent dyads completed the CFC-QoL which queries the following QoL domains: Bullying, Peer Problems, Psychological Impact, Family Support, Appearance Satisfaction, and Desire for Appearance Change. Stepwise multivariate linear regressions were performed for each QoL domain. SETTING: Urban tertiary care center. PATIENTS, PARTICIPANTS: Pediatric patients with facial differences, and their parents. INTERVENTION: Survey study. MAIN OUTCOME MEASURE(S): Demographic, diagnostic, and surgical characteristics were collected. Surgical burden was calculated as the standard deviation from the mean number of surgeries per diagnostic cohort. RESULT: Patients (N = 168) were majority female (57.1%) and Hispanic (64.3%). Diagnoses were cleft lip and/or palate (CLP,n = 99) or other craniofacial conditions (CFC,n = 69). Average patient age was 2.3 ± 5.6 years at first reconstructive surgery and 12.3 ± 3.4 years at study enrollment. Patients received an average of 4.3 ± 4.1 reconstructive surgeries.Worse Bullying was associated with higher surgical burden. Worse Peer Problems was associated with higher surgical burden, but only for children with non-CLP CFCs. Worse Family Support was associated with CFC diagnosis, female sex, and higher surgical burden. Worse Psychological Impact was associated with higher surgical burden. Worse Appearance Satisfaction was associated with younger age and with lower surgical burden. Greater Desire for Appearance Change was associated with older age, higher surgical burden, CLP diagnosis, female sex, and non-Hispanic ethnicity. Socioeconomic status did not predict QoL per patient self- or parent-proxy report. CONCLUSIONS: Higher surgical burden was associated with worse QoL outcomes in multiple domains.

Evaluation of Measurement Properties and Differential Item Functioning in the English and French Versions of the University of California, Los Angeles, Loneliness Scale-6: A Scleroderma Patient-Centered Intervention Network (SPIN) Study.

OBJECTIVE: Loneliness has been associated with poorer health-related quality of life but has not been studied in patients with systemic sclerosis (SSc). The current study was undertaken to examine and compare the psychometric properties of the English and French versions of the University of California, Los Angeles, Loneliness Scale-6 (ULS-6) in patients with SSc during the COVID-19 pandemic. METHODS: This study used baseline cross-sectional data from 775 adults enrolled in the Scleroderma Patient-Centered Intervention Network (SPIN) COVID-19 Cohort. Reliability and validity of ULS-6 scores overall and between languages were evaluated using confirmatory factor analysis (CFA), differential item functioning (DIF) through the multiple-indicator multiple-cause (MIMIC) model, omega/alpha calculation, and correlations of hypothesized convergent relationships. RESULTS: CFA for the total sample supported the single-factor structure (comparative fit index [CFI] 0.96, standardized root mean residual [SRMR] 0.03), and all standardized factor loadings for items were large (0.60-0.86). The overall MIMIC model with language as a covariate fit well (CFI 0.94, SRMR 0.04, root mean square error of approximation 0.11). Statistically significant DIF was found for 3 items across language (ßitem2  = 0.14, P < 0.001; ßitem4  = -0.07, P = 0.01; ßitem6  = 0.13, P < 0.001), but these small differences were without practical measurement implications. Analyses demonstrated high internal consistency with no language-based convergent validity differences. CONCLUSION: Analyses demonstrated evidence of acceptable reliability and validity of ULS-6 scores in English- and French-speaking adults with SSc. DIF analysis supported use of the ULS-6 to examine comparative experiences of loneliness without adjusting for language.

Hybrid argon plasma coagulation in Barrett's esophagus: a systematic review and meta-analysis.

BACKGROUND/AIMS: Patients with Barrett's esophagus are at increased risk of developing esophageal adenocarcinoma. Endoscopic therapies aim to eradicate dysplastic and metaplastic tissues. Hybrid argon plasma coagulation (hybrid-APC) utilizes submucosal fluid injection to create a protective cushion prior to ablation that shields the submucosa from injury. We performed a pooled meta-analysis to evaluate the safety and efficacy of hybrid-APC. METHODS: We conducted a systematic search of major electronic databases in April 2022. Studies that included patients with dysplastic and non-dysplastic Barrett's esophagus undergoing treatment with hybrid-APC were eligible for inclusion. Outcome measures included complete remission of intestinal metaplasia (CR-IM), stricture formation, serious adverse events, and number of sessions necessary to achieve CR-IM. RESULTS: Overall pooled CR-IM rate for patients undergoing hybrid-APC was 90.8% (95% confidence interval [CI], 0.872-0.939; I2=0%). Pooled stricture rate was 2.0% (95% CI, 0.005-0.042; I2=0%). Overall serious adverse event rate was 2.7% (95% CI, 0.007-0.055; I2=0%). CONCLUSION: Results of the current meta-analysis suggest that hybrid-APC is associated with high rates of CR-IM and a favorable safety profile. Interpretation of these results is limited by the inclusion of retrospective cohort and case series data. Randomized controlled trials that standardize treatment and outcome evaluation protocols are necessary to understand how this treatment option is comparable to the current standards of care.

Transoral incisionless fundoplication for recurrent symptoms after laparoscopic fundoplication.

BACKGROUND: Revision of a failed laparoscopic fundoplication carries higher risk of complication and lower chance of success compared to the original surgery. Transoral incisionless fundoplication (TIF) may be an endoscopic alternative for select GERD patients without need of a moderate/large hiatal hernia repair. The aim of this study was to assess feasibility, efficacy, and safety of TIF 2.0 after failed laparoscopic Nissen or Toupet fundoplication (TIFFF). METHODS: This is a multicenter retrospective cohort study of patients who underwent TIFFF between September 2017 and December 2020 using TIF 2.0 technique (EsophyX Z/Z+) performed by gastroenterologists and surgeons. Patients were included if they had (1) recurrent GERD symptoms, (2) pathologic reflux based upon pH testing or Grade C/D esophagitis or Barrett's esophagus, and (3) hiatal hernia ≤ 2 cm. The primary outcome was improvement in GERD Health-Related Quality of Life (GERD-HRQL) post-TIFFF. The TIFFF cohort was also compared to a similar surgical re-operative cohort using propensity score matching. RESULTS: Twenty patients underwent TIFFF (median 4.1 years after prior fundoplication) and mean GERD-HRQL score improved from 24.3 ± 22.9 to 14.75 ± 21.6 (p = 0.014); mean Reflux Severity Index (RSI) score improved from 14.1 ± 14.6 to 9.1 ± 8.0 (p = 0.046) with 8/10 (80%) of patients with normal RSI (< 13) post-TIF. Esophagitis healed in 78% of patients. PPI use decreased from 85 to 55% with 8/20 (45%) patients off of PPI. Importantly, mean acid exposure time decreased from 12% ± 17.8 to 0.8% ± 1.1 (p = 0.028) with 9/9 (100%) of patients with normalized pH post-TIF. There were no statistically significant differences in clinical efficacy outcomes between TIFFF and surgical revision, but TIFFF had significantly fewer late adverse events. CONCLUSION: Endoscopic rescue with TIF is a safe and efficacious alternative to redo laparoscopic surgery in symptomatic patients with appropriate anatomy and objective evidence of persistent or recurrent reflux.

Combination Topical Epinephrine and Non-steroidal Inflammatory Drugs in the Prevention of Post-ERCP Pancreatitis: A Systematic Review.

BACKGROUND: The utility of combination rectal NSAID and topical epinephrine (EI) or rectal NSAID and normal saline (SI) sprayed on duodenal papilla in the prevention of post-ERCP pancreatitis (PEP) has been studied but results have been conflicting. AIMS: To evaluate the benefit of using combination prophylaxis in preventing PEP. METHODS: A literature search was performed using Scopus, PubMed/MEDLINE, and Cochrane databases in May 2021. Randomized controlled trials (RCTs) involving adults patients who underwent ERCP and received EI versus SI were eligible for inclusion. The pooled effect was expressed as odds ratio (OR) to assess the rate of PEP, severity of PEP, and specific adverse events. The results were pooled using Reviewer Manager 5.4 software. RESULTS: Six RCTs involving 4016 patients were included in the final analysis. The EI group did not demonstrate any significant benefit over SI group in preventing PEP (OR = 1.00, 95% CI [0.68, 1.45], P = 0.98), irrespective of gender or the epinephrine concentration used. The tests for subgroup differences were not statistically significant with P-values of 0.66 and 0.28, respectively. The addition of topical epinephrine to rectal NSAID did not improve the rate of moderate to severe PEP (OR = 0.94, P = 0.86) or PEP in high-risk patients (OR = 1.14, 95%, P = 0.73). The rates of infection, including cholangitis and sepsis (OR = 0.63, P = 0.07), gastrointestinal bleeding (OR = 1.25, P = 0.56) and procedure-related death (OR = 0.71, P = 0.59) were similar between both groups. CONCLUSION: The addition of topical epinephrine did not demonstrate any benefit over rectal NSAID alone in preventing PEP or reducing other procedure-related adverse events.

Gastrointestinal Manifestations of Coronavirus Disease 2019 Across the United States: A Multicenter Cohort Study.

Background and Aims: Gastrointestinal (GI) symptoms occur among patients diagnosed with coronavirus disease 2019 (COVID-19), and there is clear evidence that SARS-CoV-2, the causative pathogen, infects the GI tract. In this large, multicenter cohort study, we evaluated variations in gastrointestinal and hepatic manifestations of COVID-19 throughout the United States (US). Methods: Patients hospitalized with a positive COVID-19 test prior to October 2020 were identified at 7 US academic centers. Demographics, presenting symptoms, laboratory data, and hospitalization outcomes were abstracted. Descriptive and regression analyses were used to evaluate GI manifestations and their potential predictors. Results: Among 2031 hospitalized patients with COVID-19, GI symptoms were present in 18.9%; diarrhea was the most common (15.2%), followed by nausea and/or vomiting (12.6%) and abdominal pain (6.0%). GI symptoms were less common in the Western cohort (16.0%) than the Northeastern (25.6%) and Midwestern (26.7%) cohorts. Compared to nonintensive care unit (ICU) patients, ICU patients had a higher prevalence of abnormal aspartate aminotransferase (58.1% vs 37.3%; P < .01), alanine aminotransferase (37.5% vs 29.3%; P = .01), and total bilirubin (12.7% vs 9.0%; P < .01). ICU patients also had a higher mortality rate (22.7% vs 4.7%; P < .01). Chronic liver disease was associated with the development of GI symptoms. Abnormal aspartate aminotransferase or alanine aminotransferase was associated with an increased risk of ICU admission. Conclusion: We present the largest multicenter cohort of patients with COVID-19 across the United States. GI manifestations were common among patients hospitalized with COVID-19, although there was significant variability in prevalence and predictors across the United States.

A Comparison of Logistic Regression Against Machine Learning Algorithms for Gastric Cancer Risk Prediction Within Real-World Clinical Data Streams.

PURPOSE: Noncardia gastric cancer (NCGC) is a leading cause of global cancer mortality, and is often diagnosed at advanced stages. Development of NCGC risk models within electronic health records (EHR) may allow for improved cancer prevention. There has been much recent interest in use of machine learning (ML) for cancer prediction, but few studies comparing ML with classical statistical models for NCGC risk prediction. METHODS: We trained models using logistic regression (LR) and four commonly used ML algorithms to predict NCGC from age-/sex-matched controls in two EHR systems: Stanford University and the University of Washington (UW). The LR model contained well-established NCGC risk factors (intestinal metaplasia histology, prior Helicobacter pylori infection, race, ethnicity, nativity status, smoking history, anemia), whereas ML models agnostically selected variables from the EHR. Models were developed and internally validated in the Stanford data, and externally validated in the UW data. Hyperparameter tuning of models was achieved using cross-validation. Model performance was compared by accuracy, sensitivity, and specificity. RESULTS: In internal validation, LR performed with comparable accuracy (0.732; 95% CI, 0.698 to 0.764), sensitivity (0.697; 95% CI, 0.647 to 0.744), and specificity (0.767; 95% CI, 0.720 to 0.809) to penalized lasso, support vector machine, K-nearest neighbor, and random forest models. In external validation, LR continued to demonstrate high accuracy, sensitivity, and specificity. Although K-nearest neighbor demonstrated higher accuracy and specificity, this was offset by significantly lower sensitivity. No ML model consistently outperformed LR across evaluation criteria. CONCLUSION: Drawing data from two independent EHRs, we find LR on the basis of established risk factors demonstrated comparable performance to optimized ML algorithms. This study demonstrates that classical models built on robust, hand-chosen predictor variables may not be inferior to data-driven models for NCGC risk prediction.

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.

Endoscopic Ultrasound-Guided Porto-systemic Pressure Gradient Measurement Correlates with Histological Hepatic Fibrosis.

BACKGROUND AND AIMS: Endoscopic ultrasound is a novel diagnostic approach to chronic liver diseases (CLDs), and EUS-guided porto-systemic pressure gradient measurement (EUS-PPG) is an important expansion with a well-developed technique. However, the clinical value and applicability of EUS-PPG measurement in predicting histologically advanced hepatic fibrosis remain unknown. METHODS: This was a single-center retrospective study on patients with various CLDs undergoing EUS-PPG and EUS-guided liver biopsy (EUS-bx) to assess if EUS-PPG measurements correlate with histological fibrosis stage and various surrogate markers for severity of CLDs and its safety. Cases with EUS-PPG were identified at the University of California Irvine, a tertiary endoscopy center, between January 2014 and March 2020. RESULTS: In 64 patients, the mean age was 57.5; 40 (62.5%), males; mean Child-Turcotte-Pugh (CTP) and Model for End-Stage Liver Disease (MELD) scores, 5.9 and 10.4, respectively. The procedure success rate was 100%. Twenty-nine (45.3%) had EUS-PPG ≥ 5 mmHg that was associated with clinical cirrhosis (p < 0.0001), clinical portal hypertension (p = 0.002), hepatic decompensation (p = 0.013), MELD-Na > 10 (p = 0.036), PLTs ≤ 120 × 109/L (p = 0.001), INR ≥ 1.05 (p = 0.007), presence of EV, GV, or PHG (p < 0.0001), biopsy-proven fibrosis stage ≥ 3 (p = 0.002), APRI > 2 (p = 0.001), and FIB-4 > 3.25 (p = 0.001). Multivariable analysis confirmed that EUS-PPG ≥ 5 mmHg was significantly associated with liver biopsy-proven fibrosis stage ≥ 3 (LR 27.0, 95% CI = 1.653-360.597, p = 0.004), independent of C-cirrhosis, C-PHTN, thrombocytopenia, splenomegaly, and APRI score > 2, and FIB-4 score > 3.25. There were no serious complications related to EUS-PPG procedures. CONCLUSIONS: EUS-PPG measurements provide excellent correlation with histological hepatic fibrosis stage and various clinical, laboratory, endoscopic and imaging variables indicative of advanced liver disease without serious adverse events.

Novel Interdisciplinary Approach to GERD: Concomitant Laparoscopic Hiatal Hernia Repair with Transoral Incisionless Fundoplication.

BACKGROUND: Transoral incisionless fundoplication (TIF) is an endoscopic alternative for the treatment of GERD. However, TIF does not address the hiatal hernia (HH). We present a novel approach with a laparoscopic HH repair followed by same-session TIF, coined concomitant transoral incisionless fundoplication (cTIF). The aim of this study was to assess the efficacy, safety, and feasibility of cTIF in a collaborative approach between Gastroenterology and surgery. STUDY DESIGN: Patients with confirmed GERD and >2 cm HH who underwent cTIF between 2018 and 2020 were included. Symptoms were assessed using the Reflux Disease Questionnaire, GERD Health-Related Quality of Life Index, and the Reflux Symptom Index pre and post cTIF. One-way ANOVA and paired samples t-test were used for statistical analysis. RESULTS: Sixty patients underwent cTIF (53% were men, mean age was 59.3 years) with 100% technical success. Mean ± SD HH measurement on endoscopy was 2.9 ± 1.5 cm. Scores on Reflux Disease Questionnaire for symptom frequency and symptom severity improved significantly from before to 6 months after cTIF (17.4 to 4.72; p < 0.01 and 16.7 to 4.56; p < 0.05, respectively). According to the GERD Health-Related Quality of Life Index, significant decreases were seen post cTIF in heartburn (23.26 to 7.37; p < 0.01) and regurgitation (14.26 to 0; p = 0.05). Reflux Symptom Index similarly decreased after cTIF (17.7 to 8.1 post cTIF; p < 0.01). Mean DeMeester score decreased from 43.7 to 4.9 and acid exposure time decreased from 12.7% to 1.28% post cTIF (p = 0.06). CONCLUSIONS: We present a novel multidisciplinary approach to GERD using a combined endoscopic and surgical approach with close collaboration between Gastroenterology and surgery. Our results suggest that cTIF is safe and effective in reducing reflux symptoms in a large spectrum of GERD patients.

Underwater versus conventional EMR for colorectal polyps: systematic review and meta-analysis.

BACKGROUND AND AIMS: Underwater EMR (UEMR) has emerged as an attractive alternative to conventional EMR (CEMR) for the resection of colorectal polyps. The purpose of this systematic review and meta-analysis was to compare UEMR and CEMR for the resection of colorectal polyps with respect to efficacy and safety. METHODS: A literature search was performed across multiple databases, including MEDLINE/PubMed, The Cochrane Library, CINAHL, Google Scholar, and Scopus, for studies that were published until May 2020. Only studies that compared the resection of colorectal polyps using UEMR with CEMR were included. Outcomes examined included rates of en bloc resection, recurrence, postprocedure bleeding, perforation, and resection time. RESULTS: Seven studies totaling 1237 polyps were included: 614 polyps were resected with UEMR and 623 polyps with CEMR. UEMR was associated with a significant increase in the rate of overall en bloc resection (odds ratio [OR], 1.84; 95% confidence interval [CI], 1.42-2.39; P < .001; I2 = 38%), with subgroup analysis showing a significant increase in the rates of en bloc resection in polyps ≥20 mm (OR, 1.51; 95% CI, 1.06-2.14; P = .02; I2 = 44%) but not in polyps <20 mm (OR, 1.07; 95% CI, .65-1.76; P = .80; I2 = 27%), and with a significant reduction in the rate of recurrence (OR, .30; 95% CI, .16-.57; P = .0002; I2 = 0%), again driven by improvements in polyps ≥20 mm. There was no significant difference in postprocedure bleeding (OR, 1.11; 95% CI, .57-2.17; P = .76; I2 = 0%) or perforation (OR, .72; 95% CI, .19-2.83; P = .64; I2 = 0%). CONCLUSIONS: The results of this systematic review and meta-analysis demonstrate that UEMR is a safe and efficacious alternative to CEMR. With appropriate training, UEMR may be strongly considered as a first-line option for resection of colorectal polyps.

Prevalence, risk factors, and surveillance patterns for gastric intestinal metaplasia among patients undergoing upper endoscopy with biopsy.

BACKGROUND AND AIMS: Gastric intestinal metaplasia (GIM) is an important precursor lesion to gastric cancer (GC), the second leading cause of cancer death worldwide. There exist few data regarding the prevalence of, risk factors for, and clinical practice patterns regarding GIM in the United States. Furthermore, there are currently no U.S. guidelines regarding screening/surveillance for GIM. METHODS: All consecutive upper endoscopic procedures from 2 academic medical centers in Seattle between 1999 and 2014 were reviewed. Demographic, clinical, and endoscopic covariates were recorded at time of endoscopy. Procedures with gastric biopsy were matched to final the histologic diagnoses, including the presence of Helicobacter pylori. Cases of GIM and dysplasia were recorded and compared with non-GIM controls using univariate and multivariable regression. Surveillance patterns for cases of GIM were recorded. RESULTS: Data from 36,799 upper endoscopies, 17,710 gastric biopsies, 2073 cases of GIM, 43 cases of dysplasia, and 78 cases of GC were captured. The point prevalence of GIM was 11.7% in patients who underwent gastric biopsy. Non-white race (P < .001), increasing age (P < .001), and presence of H pylori (P < .001) were associated with GIM. If GIM was present, increasing age (P < .001) and male gender (P < .001) were associated with progression, and the presence of H pylori (P < .001) was inversely associated with progression to dysplasia/GC. Few cases of GIM/dysplasia/GC were identified during procedures for GIM screening/surveillance. Only 16% of patients with a diagnosis of GIM received a recommendation for surveillance. CONCLUSIONS: There is a high prevalence of GIM among non-white and Hispanic Americans. Risk factors for development of GIM may be distinct from the risk factors for progression to GC.
