Sessile serrated lesion prevalence and factors associated with their detection: a post-hoc analysis of a multinational randomized controlled trial from Asia.

BACKGROUND: Sessile serrated lesions (SSLs) are associated with an increased risk of colorectal cancer. Data on the prevalence of SSLs in Asia are limited. We performed this study to estimate the prevalence of SSLs in Asia and to explore endoscopic factors that are associated with SSL detection. METHODS: This is a post-hoc analysis of a multicenter randomized controlled trial from four Asian countries/regions that compared adenoma detection rates using linked-color imaging (LCI) and white-light imaging. Colonoscopies were performed in an average-risk population for screening, diagnostic examination, or polyp surveillance. Patients with SSLs were compared against those without SSLs to evaluate for possible predictors of SSL detection using Firth's logistic regression. RESULTS: 2898 participants (mean age 64.5 years) were included in the analysis. The estimated prevalence of SSLs was 4.0% (95%CI 3.4%-4.8%), with no sex or age group differences. On multivariable analysis, use of LCI (adjusted odds ratio [aOR] 1.63, 95%CI 1.10-2.41), experienced endoscopists (aOR 1.94, 95%CI 1.25-3.00), use of transparent cap (aOR 1.75, 95%CI 1.09-2.81), and longer withdrawal time (aOR 1.06, 95%CI 1.03-1.10) were independently associated with SSL detection. Synchronous adenoma detection (aOR 1.89, 95%CI 1.20-2.99) was also predictive of SSL detection. CONCLUSION: The prevalence of SSLs in Asia is 4.0%. Use of LCI or a transparent cap, greater endoscopist experience, and longer withdrawal time were all associated with increased SSL detection.

Linked color imaging improves colorectal lesion detection especially for low performance endoscopists: An international trial in Asia.

BACKGROUND AND AIM: Linked color imaging (LCI) is an image-enhanced endoscopy technique that accentuates the color difference between red and white, potentially improving the adenoma detection rate (ADR). However, it remains unclear whether LCI performance in detecting colorectal lesions differs based on endoscopists' experience levels. We aimed to evaluate the differences in LCI efficacy based on the experience levels of endoscopists by conducting an exploratory analysis. METHODS: In this post hoc analysis of an international randomized controlled trial comparing the detection of adenoma and other lesions using colonoscopy with LCI and high-definition white light imaging (WLI), we included patients from 11 institutions across four countries/regions: Japan, Thailand, Taiwan, and Singapore. We retrospectively reviewed differences in the lesion detection of LCI according to endoscopists' colonoscopy history or ADR. RESULTS: We included 1692 and 1138 patients who underwent colonoscopies performed by 54 experts (experience of ≥ 5000 colonoscopies) and by 43 non-experts (experience of < 5000 colonoscopies), respectively. Both expert and non-expert groups showed a significant improvement in ADR with LCI compared to WLI (expert, 61.7% vs 46.4%; P < 0.001; non-expert, 56.6% vs 46.4%; P < 0.001). LCI had no effect on sessile serrated lesion detection rate in non-experts (3.1% vs 2.5%; P = 0.518). LCI significantly improved detection rates in endoscopists with relatively low detection performance, defined as an ADR < 50%. CONCLUSIONS: This exploratory study analyzed data from a previous trial and revealed that LCI is useful for both experts and non-experts and is even more beneficial for endoscopists with relatively low detection performance using WLI.

Analysis of the Characteristics of Coexisting Lesions in Colorectal Cancer Patients in an International Study: A Subgroup Analysis of the ATLAS Trial.

INTRODUCTION: We investigated coexisting lesion types in patients with invasive colorectal cancer (CRC) in a multinational study for comprehending the adenoma-carcinoma and serrated pathway about the development of CRC. METHODS: We retrospectively reviewed 3,050 patients enrolled in the international randomized controlled trial (ATLAS study) to evaluate the colorectal polyp detection performance of image-enhanced endoscopy in 11 institutions in four Asian countries/regions. In the current study, as a subgroup analysis of the ATLAS study, 92 CRC patients were extracted and compared to 2,958 patients without CRC to examine the effects of age, sex, and coexisting lesion types (high-grade adenoma [HGA], low-grade adenoma with villous component [LGAV], 10 adenomas, adenoma ≥10 mm, sessile serrated lesions [SSLs], and SSLs with dysplasia [SSLD]). Additional analyses of coexisting lesion types were performed according to sex and location of CRC (right- or left-sided). RESULTS: A multivariate analysis showed that HGA (odds ratio [95% confidence interval] 4.29 [2.16-8.18]; p < 0.01), LGAV (3.02 [1.16-7.83], p = 0.02), and age (1.04 [1.01-1.06], p = 0.01) were independently associated with CRC. According to sex, the coexisting lesion types significantly associated with CRC were LGAV (5.58 [1.94-16.0], p < 0.01) and HGA (4.46 [1.95-10.20], p < 0.01) in males and HGA (4.82 [1.47-15.80], p < 0.01) in females. Regarding the location of CRC, SSLD (21.9 [1.31-365.0], p = 0.03) was significant for right-sided CRC, and HGA (5.22 [2.39-11.4], p < 0.01) and LGAV (3.46 [1.13-10.6], p = 0.02) were significant for left-sided CRC. CONCLUSIONS: The significant coexisting lesions in CRC differed according to sex and location. These findings may contribute to comprehending the pathogenesis of CRC.

Linked-Color Imaging Detects More Colorectal Adenoma and Serrated Lesions: An International Randomized Controlled Trial.

BACKGROUND & AIMS: Effects of linked-color imaging (LCI) on colorectal lesion detection and colonoscopy quality remain controversial. This study compared the detection rates of adenoma and other precursor lesions using LCI vs white-light imaging (WLI) during screening, diagnostic, and surveillance colonoscopies. METHODS: This randomized controlled trial was performed at 11 institutions in 4 Asian countries/regions. Patients with abdominal symptoms, a primary screening colonoscopy, positive fecal immunochemical test results, or undergoing postpolypectomy surveillance were recruited and randomly assigned in a 1:1 ratio to either the LCI or high-definition WLI group. The primary outcome was adenoma detection rate (ADR). Secondary outcomes were polyp detection rate, advanced ADR, sessile serrated lesion (SSL) detection rate, and the mean number of adenomas per colonoscopy. The recommended surveillance schedule distribution after trial colonoscopy was analyzed. RESULTS: Between November 2020 and January 2022, there were 3050 participants (LCI, n = 1527; WLI, n = 1523) recruited. The LCI group ADR was significantly higher than the WLI group ADR using intention-to-treat (58.7% vs 46.7%; P < .01) and per-protocol analyses (59.6% vs 46.4%; P < .01). The LCI group polyp detection rates (68.6% vs 59.5%; P < .01), SSL detection rates (4.8% vs 2.8%; P < .01), and adenomas per colonoscopy (1.48 vs 1.02; P < .01) also were significantly higher. However, the advanced ADR was not significantly different (13.2% vs 11.0%; P = .06). Significantly more patients in the LCI group had shorter recommended surveillance schedules than the WLI group (P < .01). CONCLUSIONS: Compared with WLI, LCI improved adenoma and other polyp detection rates, including SSLs, resulting in alteration of the recommended surveillance schedule after screening, diagnostic, and postpolypectomy surveillance colonoscopies.

Virtual reality distraction during upper gastrointestinal endoscopy: a randomized controlled trial.

BACKGROUND AND AIM: Virtual reality (VR) is an established and effective tool in reducing autonomic and somatic pain. We aimed to examine the analgesic effects of VR distraction during esophagogastroduodenoscopy (EGD). METHODS: We conducted a randomized controlled trial and enrolled patients who had indication for unsedated EGD with topical anesthesia. Patients were randomly assigned to use Oculus GO with three-dimensional specific software content (standalone VR headset), sham VR or without VR during EGD. The primary outcome was patient pain scores during EGD. RESULTS: A total of 96 patients undergoing diagnostic EGD were randomized to receive VR (n = 32), sham VR (n = 32), and no VR defined as the control group (n = 32). Patients in all groups reported no statistically different pain during esophageal intubation. The mean pain score was 2.7 ± 2.4 in the VR group, 2.7 ± 2.5 in the sham VR and 2.3 ± 2.3 in the control group, (P value = 0.751). No significant difference was observed in heart rate and blood pressure, and the endoscopists reported higher overall satisfaction scores in VR (4.3 ± 0.5) compared with the control group (4 ± 0.8) but without significance (P value = 0.156). CONCLUSION: Virtual reality-assisted anesthesia during EGD did not significantly reduce patient pain during esophageal intubation. There was no superiority in using VR distraction regarding patient's and endoscopist's satisfaction compared with standard EGD without VR Further studies are required to detect any true clinical advantage of VR distraction during EGD.

Curcuma longa Linn versus omeprazole in treatment of functional dyspepsia: A randomized, double-blind, placebo-controlled trial.

BACKGROUND AND AIMS: Functional dyspepsia (FD) is a common problem in gastroenterology practice. The study aimed to compare the efficacy of Curcuma longa Linn versus omeprazole and placebo among patients diagnosed with FD. METHODS: From November 2017 to November 2018, patients diagnosed with FD according to ROME IV criteria were enrolled. Patients were randomized into curcumin, omeprazole, or placebo groups. The Severity of Dyspepsia Assessment (SODA) was used to evaluate clinical effectiveness after 2 and 4 weeks. Health-related quality of life was assessed using the EuroQol-5 Dimension questionnaire. RESULTS: A total of 132 patients were randomized. Forty-five, 43, and 44 patients were in the curcumin, omeprazole, and placebo groups, respectively. At 4 weeks, the mean SODA score change of pain and non-pain symptoms decreased in the curcumin group compared with the placebo group (pain -16.98 ± 8.09 vs -10.53 ± 4.43; P < 0.001, non-pain -7.96 ± 3.41 vs -6.05 ± 3.03; P < 0.008). No significant difference was observed between curcumin and omeprazole groups (pain -16.98 ± 8.09 vs -14.69 ± 6.41; P = 0.302, non-pain -7.96 ± 3.41 vs -7.07 ± 2.27; P = 0.486). The mean change of the SODA satisfaction score at 4 weeks was higher in the curcumin group compared with the omeprazole group but without statistical significance (9.17 ± 3.88 vs 8.63 ± 3.89, P = 1). The mean change of EQ-5D index at 4 weeks was highest in the curcumin group but not statistically different from other groups (0.12 ± 0.13 vs 0.09 ± 0.10 vs 0.07 ± 0.05; P = 0.055). CONCLUSION: Curcuma longa Linn can improve dyspeptic symptoms, improve quality of life, and provide satisfaction equivalent to omeprazole in treatment of FD.

Thailand guideline 2020 for medical management of gastroesophageal reflux disease.

Gastroesophageal reflux disease (GERD) is one of the most prevalent and bothersome functional gastrointestinal disorders worldwide, including in Thailand. After a decade of the first Thailand GERD guideline, physician and gastroenterologist encountered substantially increase of patients with GERD. Many of them are complicated case and refractory to standard treatment. Concurrently, the evolution of clinical characteristics as well as the progression of investigations and treatment have developed and changed tremendously. As a member of Association of Southeast Asian Nations, which are developing countries, we considered that the counterbalance between advancement and sufficient economy is essential in taking care of patients with GERD. We gather physicians from university hospitals, as well as internist and general practitioners who served in rural area, to make a consensus in this updated version of GERD guideline focusing in medical management of GERD. This clinical practice guideline was constructed adhering with standard procedure. We categorized the guideline in to four parts including definition, investigation, treatment, and long-term follow up. We anticipate that this guideline would improve physicians' proficiency and help direct readers to choose investigations and treatments in patients with GERD wisely. Moreover, we wish that this guideline would be applicable in countries with limited resources as well.

Health care burden and mortality of acute on chronic liver failure in Thailand: a nationwide population-based cohort study.

BACKGROUND: Accurate population-based data are required concerning the rate, economic impact, and long-term outcome from acute on chronic liver failures (ACLF) in hospitalized patients with cirrhosis. We aimed to discover time trends for the epidemiology, economic burden, and mortality of ACLF in Thailand. METHODS: We conducted a nationwide, population-based, cohort study which involved all hospitalized patients with cirrhosis in Thailand during the period between 2009 and 2013, with data from the National Health Security Office. ACLF was defined by two or more extrahepatic organ failures in patients with cirrhosis. Primary outcomes were trends in hospitalizations, hospital costs, together with inpatient mortality. RESULTS: The number of ACLF hospitalizations in Thailand doubled between 3185 in 2009 and 7666 in 2013. The average cost of each ACLF hospitalization was 3.5-fold higher than for cirrhosis ($ 1893 versus $ 519). The hospital is paid using a diagnosis-related group (DRG) payment system that is only 15% of the average treatment costs ($ 286 from $ 1893). The in-hospital fatality rate was 51% for ACLF while the additional fatality rate was 85% up to 1 year. The ACLF organ failure trends indicated sepsis with septic shock and renal failure as the majority proportion. Age, the number and types of organ failure and male sex were predictors of ACLF death. CONCLUSIONS AND RELEVANCE: Cirrhosis and ACLF both represent substantial and increasing health and economic burdens for Thailand. These data can assist national health care policy stakeholders to target high-risk patients with cirrhosis for care.

Improvement of Gut Diversity and Composition After Direct-Acting Antivirals in Hepatitis C Virus-Infected Patients With or Without Human Immunodeficiency Virus Coinfection.

BACKGROUND: The influence of direct-acting antivirals (DAAs) on the composition of gut microbiota in hepatitis C virus (HCV)-infected patients with or without human immunodeficiency virus (HIV) is unclear. METHODS: We enrolled 62 patients with HCV monoinfection and 24 patients with HCV/HIV coinfection receiving elbasvir-grazoprevir from a clinical trial. Fecal specimens collected before treatment and 12 weeks after treatment were analyzed using amplicon-based 16S ribosomal RNA sequencing. RESULTS: Sustained virological response rates in the monoinfection and coinfection groups were similar (98.4% vs 95.8%). Pretreatment bacterial communities in the patient groups were less diverse and distinct from those of healthy controls. Compared with HCV-monoinfected patients, HCV/HIV-coinfected individuals showed comparable microbial alpha diversity but decreased Firmicutes-Bacteroidetes ratios. The improvement of microbial dysbiosis was observed in responders achieving sustained virological response across fibrosis stages but was not found in nonresponders. Responders with a low degree of fibrosis exhibited a recovery in alpha diversity to levels comparable to those in healthy controls. Reciprocal alterations of increased beneficial bacteria and reduced pathogenic bacteria were also observed in responders. CONCLUSIONS: This study indicates a short-term effect of direct-acting antivirals in restoration of microbial dysbiosis. The favorable changes in gut microbiota profiles after viral eradication might contribute toward the reduction of HCV-related complications among infected individuals.

Comparison of aggressive versus standard intravenous hydration for clinical improvement among patients with mild acute pancreatitis: A randomized controlled trial.

BACKGROUND: Controversy remains regarding fluid management strategy, optimal volume and rate of intravenous fluid in mild acute pancreatitis. We performed a randomized controlled trial to compare clinical improvement and inflammatory markers between aggressive and standard fluid management. METHODS: A single center prospective randomized controlled trial was conducted in a tertiary care hospital. We randomized patients with a diagnosis of mild acute pancreatitis using revised Atlanta classification in two groups, the aggressive (20 ml/kg bolus followed by 3 ml/kg/hr) and standard (10 ml/kg bolus followed by 1.5 ml/kg/hr) intravenous hydration with Lactated Ringer's solution. Primary outcome was clinical improvement at 24 and 36 hours. RESULTS: The mean age of patients was 46 years and 34 patients (77%) were male. The average volumes of fluid during the first 24 hours in aggressive and standard groups was 4886 ml (71 ml/kg) and 3985 ml (53 ml/kg), respectively; p-value 0.002. Aggressive intravenous hydration did not significantly improve clinical outcome compared with standard intravenous hydration (45.45% vs. 31.82%, respectively; p-value 0.353). However, subgroup analysis between patients with obese and non-obese status, revealed aggressive intravenous hydration significantly improved clinical outcome within the first 24 hours in obese group. CONCLUSION: Aggressive intravenous hydration with Lactated Ringer's solution did not improve clinical outcome in mild acute pancreatitis but showed statistically significant improvement only in patients with obese status. Future studies should include a larger sample size to confirm these findings.

Comparison of normal saline versus Lactated Ringer's solution for fluid resuscitation in patients with mild acute pancreatitis, A randomized controlled trial.

BACKGROUND/OBJECTIVES: Aggressive fluid resuscitation is recommended for initial management of acute pancreatitis. However, there are few studies which focus on types of fluid therapy. METHODS: We performed a randomized controlled trial in patients with acute pancreatitis. The patients were randomized into two groups. Each group received Normal Saline solution (NSS) or Lactated Ringer's solution (LRS) through a goal-directed fluid resuscitation protocol. Systemic inflammatory response syndrome (SIRS) at 24 and 48 h, mortality, presence of local complications and inflammatory markers were measured. RESULTS: Forty-seven patients were included. Twenty-four patients (51%) received NSS and 23 patients received LRS. There was significant reduction in SIRS after 24 h among subjects who resuscitated with LRS compared with NSS (4.2% in NSS, 26.1% in LRS, P = 0.02). However, SIRS reduction at 48 h was not different between groups (33.4% in NSS, 26.1% in LRS, P = 0.88). Mortality was not different between NSS and LRS (4.2% in NSS, 0% in LRS, P = 1.00). CRP, ESR and procalcitonin increased at 24 h and 48 h after admission with no difference between the two groups. Local complications were 29.2% in NSS and 21.7% in LRS (P = 0.74). The median length of hospital stay was not significantly different in the two groups (5.5 days in NSS, 6 days in LRS, P = 0.915). CONCLUSIONS: Lactated Ringer's solution was superior to NSS in SIRS reduction in acute pancreatitis only in the first 24 h. But SIRS at 48 h and mortality were not different between LRS and NSS.

Adding C-reactive protein and procalcitonin to the model of end-stage liver disease score improves mortality prediction in patients with complications of cirrhosis.

BACKGROUND AND AIM: This study aims to determine the performance of models adding C-reactive protein (CRP) and procalcitonin (PCT) to the model of end-stage liver disease (MELD) score for mortality prediction in patients hospitalized with complications of cirrhosis. METHODS: A prospective cohort study was carried out in consecutive cirrhotic patients admitted with complications of cirrhosis between September 2012 and December 2013 at Phramongkutklao Hospital, Bangkok, Thailand. All patients had venous CRP, PCT, and laboratory values for MELD score calculation measured at emergency room or admission. Cox regression analysis and the c-statistic were used to predict mortality. The MELD-CRP score was externally validated in 818 eligible patients from Mayo Clinic, Rochester, using data from 1288 cirrhotic patients diagnosed between 2010 and 2014. RESULTS: A cohort of 177 patients with cirrhosis was admitted during the study period. Seventy-one patients were eligible for analysis. The MELD score was predictive of 90-day mortality odds ratio (OR) 1.19 (95% confidence interval [CI] 1.09-1.32). Adding CRP and/or PCT to the MELD score improved the predictive of 90-day mortality: MELD-CRP OR 2.71 (95% CI 1.66-4.99); MELD-PCT OR 2.72 (95% CI 1.66-4.99); MELD-CRP-PCT OR 2.71 (95% CI 1.67-4.92). The c-statistics for MELD, MELD-CRP, MELD-PCT, and MELD-CRP-PCT were 0.81, 0.83, 0.84, and 0.85, respectively. Adding CRP and/or PCT to the MELD score also improved 30-day mortality prediction. Similar results for the MELD-CRP score were obtained from the Mayo Clinic external validation cohort. CONCLUSION: The MELD-CRP, MELD-PCT, and MELD-CRP-PCT scores may be superior to the MELD score alone in predicting mortality in patients hospitalized with complications of cirrhosis.

Comparison of efficacy of pharmacological treatments for chronic idiopathic constipation: a systematic review and network meta-analysis.

OBJECTIVE: To compare efficacy of pharmacotherapies for chronic idiopathic constipation (CIC) based on comparisons to placebo using Bayesian network meta-analysis. DATA SOURCES: We conducted searches (inception to May 2015) of MEDLINE, EMBASE, Scopus and Cochrane Central, as well as original data from authors or drug companies for the medications used for CIC. STUDY SELECTION: Phase IIB and phase III randomised, placebo-controlled trials (RCT) of ≥4 weeks' treatment for CIC in adults with Rome II or III criteria for functional constipation; trials included at least one of four end points. DATA EXTRACTION AND SYNTHESIS: Two investigators independently evaluated all full-text articles that met inclusion criteria and extracted data for primary and secondary end points, risk of bias and quality of evidence. OUTCOMES: Primary end points were ≥3 complete spontaneous bowel movements (CSBM)/week and increase over baseline by ≥1 CSBM/week. Secondary end points were change from baseline (Δb) in the number of SBM/week and Δb CSBM/week. RESULTS: Twenty-one RCTs (9189 patients) met inclusion and end point criteria: 9 prucalopride, 3 lubiprostone, 3 linaclotide, 2 tegaserod, 1 each velusetrag, elobixibat, bisacodyl and sodium picosulphate (NaP). All prespecified end points were unavailable in four polyethylene glycol studies. Bisacodyl, NaP, prucalopride and velusetrag were superior to placebo for the ≥3 CSBM/week end point. No drug was superior at improving the primary end points on network meta-analysis. Bisacodyl appeared superior to the other drugs for the secondary end point, Δb in number of SBM/week. CONCLUSIONS: Current drugs for CIC show similar efficacy. Bisacodyl may be superior to prescription medications for Δb in the number of SBM/week in CIC.

Strategies to Reduce Hospital Readmissions.

After the Patient Protection and Affordable Care Act or "Obamacare" was signed into law in 2010, the problem of readmission has taken on a new sense of urgency. Hospitals with excess readmissions receive reduced reimbursement because readmission is considered to represent a poor quality measure in the healthcare delivery system. Cirrhosis places a major burden on the healthcare economy. Patients with cirrhosis frequently require hospitalization, and annual admission rates have doubled within 10 years. The costs of hospitalization associated with cirrhosis have also markedly increased. Readmissions create negative consequences for the patient and the family. Several strategies have been proposed to reduce the number of readmissions, but the efficacy of these strategies is questionable. Although the Model for End-Stage of Liver Disease (MELD) score can be a tool for risk stratification, many other factors are also independent risks for readmission. Studies aimed at the reduction of readmission in patients with cirrhosis are very limited, and much research is required before specific recommendations can be made to reduce readmissions.

Nonselective ß-Blockers and Survival in Patients With Cirrhosis and Ascites: A Systematic Review and Meta-analysis.

BACKGROUND & AIMS: Nonselective ß-blockers (NSBBs), given to reduce the risk of variceal bleeding, have been associated with increased mortality in patients with cirrhosis and refractory ascites in some, but not all, studies. We performed a systematic review and meta-analysis to evaluate the effect of NSBBs on all-cause mortality in patients with cirrhosis and refractory ascites. METHODS: We performed a comprehensive search of MEDLINE, Embase, Web of Science, and Scopus databases through January 2015, supplemented with a manual search. Trial-specific risk ratios (RRs) were pooled using the random-effects model. RESULTS: Our analysis included 3 randomized control trials and 8 observational studies of propranolol, carvedilol, nadolol, and metoprolol, reporting 1206 deaths among 3145 patients with ascites. The control groups received other interventions to prevent variceal bleeding. NSBB use was not associated with increased all-cause mortality in all patients with ascites (RR, 0.95; 95% confidence interval [CI], 0.67-1.35); nonrefractory ascites alone (RR, 0.96; 95% CI, 0.50-1.82), or refractory ascites alone (RR, 0.95; 95% CI, 0.57-1.61). Results were similar in randomized controlled trials and observational studies. Use of NSBBs was not associated with increased mortality at 6, 12, 18, and 24 months. Overall, the included studies had a medium to high risk of bias, except for 3 clinical trials in which the risk of biased was determined to be low. CONCLUSIONS: The use of NSBBs was not associated with a significant increase in all-cause mortality in patients with cirrhosis and ascites or refractory ascites. Certainty in the available estimates is low; a randomized trial of only patients with ascites is needed to answer this question. This meta-analysis does not support the position that NSBBs routinely be withheld from patients with ascites.

Use of virtual reality in patient education program to reduce anxiety in upper gastrointestinal endoscopy: A randomized controlled trial.

Background and Aim: Virtual reality (VR) provides an immersive image-viewing experience that has recently been expanding its use in clinical medicine. We aimed to examine a patient education program by VR to reduce anxiety in patients undergoing esophagogastroduodenoscopy (EGD). Methods: We conducted a randomized controlled trial and consecutively enrolled patients who had an indication for unsedated EGD with topical anesthesia. Patients were randomly assigned to use Oculus GO with three-dimensionally specific software content (a stand-alone VR headset) for patient education or standard patient education using oral information (the control group) before EGD. The primary outcome was the variation in anxiety scores before and after patient education programs. Results: A total of 107 patients underwent EGD and received a VR (n = 58) and control (n = 49) patient education program. The mean anxiety score before starting the patient education program was 41.4 9.6 in the VR group and 41.9 7.7 in the control group. The mean anxiety score after the patient education program was 37.1 10.8 in the VR group and 38.9 8.07 in the control group (P-value = 0.354). The anxiety score in the VR group decreased more than in the control group but was not significant. The recall questionnaire scores were higher in the VR group (4.70.4) than the control group (3.91, P-value 0.001). Conclusion: A virtual reality-assisted patient education program before EGD did not significantly reduce anxiety but may provide more memory and understanding about the procedure to patients who underwent unsedated EGD.

Correlation between neck circumference and hepatic steatosis determined by controlled attenuation parameter.

Neck circumference is an attractive method for determining metabolic profiles and has many advantages over waist circumference. However, the correlation between neck circumference and hepatic fibrosis has not been evaluated. The aim of this study was to evaluate the correlation between neck circumference and hepatic fibrosis and define the optimal cut-off point for neck circumference to determine hepatic fibrosis. A cross-sectional study (n = 333) was conducted among Thai healthcare workers at Phramongkutklao Hospital who received an annual health maintenance program. Neck circumference was measured at the lower margin of the laryngeal prominence. Fibroscan® with a controlled attenuation parameter was used to measure the degree of hepatic fibrosis and steatosis by an experienced, well-trained operator. In the cross-sectional analysis, it was found that the large circumference of the neck was associated with hepatic fibrosis (r = 0.19, p = .001) and hepatic steatosis (r = 0.58, p < .001). Hepatic fibrosis (r = 0.15, p = .004) and steatosis (r = 0.53, p < .001) were also associated with waist circumference. The neck circumferences of 40 and 34 cm were the best cut-offs for male and female participants, respectively.Neck circumference is closely related to hepatic fibrosis and steatosis, which should be promoted and has a better advantage than waist circumference in the screening of hepatic steatosis.

Development of a diagnostic support system for the fibrosis of nonalcoholic fatty liver disease using artificial intelligence and deep learning.

Liver fibrosis is a pathological condition characterized by the abnormal proliferation of liver tissue, subsequently able to progress to cirrhosis or possibly hepatocellular carcinoma. The development of artificial intelligence and deep learning have begun to play a significant role in fibrosis detection. This study aimed to develop SMART AI-PATHO, a fully automated assessment method combining quantification of histopathological architectural features, to analyze steatosis and fibrosis in nonalcoholic fatty liver disease (NAFLD) core biopsies and employ Metavir fibrosis staging as standard references and fat assessment grading measurement for comparison with the pathologist interpretations. There were 146 participants enrolled in our study. The correlation of Metavir scoring system interpretation between pathologists and SMART AI-PATHO was significantly correlated (Agreement = 68%, Kappa = 0.59, p-value <0.001), which subgroup analysis of significant fibrosis (Metavir score F2-F4) and nonsignificant fibrosis (Metavir score F0-F1) demonstrated substantial correlated results (agreement = 80%, kappa = 0.61, p-value <0.001), corresponding with the correlation of advanced fibrosis (Metavir score F3-F4) and nonadvanced fibrosis groups (Metavir score F0-F2), (agreement = 89%, kappa = 0.74, p-value <0.001). SMART AI-PATHO, the first pivotal artificially intelligent diagnostic tool for the color-based NAFLD hepatic tissue staging in Thailand, demonstrated satisfactory performance as a pathologist to provide liver fibrosis scoring and steatosis grading. In the future, developing AI algorithms and reliable testing on a larger scale may increase accuracy and contribute to telemedicine consultations for general pathologists in clinical practice.

Severity of COVID-19 in Patients with Diarrhoea: A Systematic Review and Meta-Analysis.

COVID-19 patients occasionally present with diarrhoea. Our objective was to estimate the risk of developing the severe disease in COVID-19 patients with and without diarrhoea and to provide a more precise estimate of the prevalence of COVID-19-associated digestive symptoms. A total of 88 studies (n = 67,794) on patients with a COVID-19 infection published between 1 January 2020 and 20 October 2022 were included in this meta-analysis. The overall prevalence of digestive symptoms was 27% (95% confidence interval (CI): 21-34%; I2 = 99%). According to our data, the pooled prevalence of diarrhoea symptoms in the 88 studies analysed was 17% (95% CI: 14-20%; I2 = 98%). The pooled estimate of nausea or vomiting in a total of 60 studies was 12% (95% CI: 8-15%; I2 = 98%). We also analysed 23 studies with eligible individuals (n = 3800) to assess the association between the disease severity and diarrhoea. Individuals who had diarrhoea were more likely to have experienced severe COVID-19 (odds ratio: 1.71; 95% CI: 1.31-2.24; p < 0.0001; I2 = 10%). Gastrointestinal symptoms and diarrhoea are frequently presenting COVID-19 manifestations that physicians should be aware of.

Characteristics of Drug-induced Liver Injury in Chronic Liver Disease: Results from the Thai Association for the Study of the Liver (THASL) DILI Registry.

Background and Aims: The impact of drug-induced liver injury (DILI) on patients with chronic liver disease (CLD) is unclear. There are few reports comparing DILI in CLD and non-CLD patients. In this study, we aimed to determine the incidence and outcomes of DILI in patients with and without CLD. Methods: We collected data on eligible individuals with suspected DILI between 2018 and 2020 who were evaluated systematically for other etiologies, causes, and the severity of DILI. We compared the causative agents, clinical features, and outcomes of DILI among subjects with and without CLD who were enrolled in the Thai Association for the Study of the Liver DILI registry. Subjects with definite, or highly likely DILI were included in the analysis. Results: A total of 200 subjects diagnosed with DILI were found in the registry. Of those, 41 had CLD and 159 had no evidence of CLD in their background. Complementary and alternative medicine (CAM) products were identified as the most common class of DILI agents. Approximately 59% of DILI in the CLD and 40% in non-CLD group were associated with CAM use. Individuals with pre-existing CLD had similar severity including mortality. Twelve patients (6%) developed adverse outcomes related to DILI including seven (3.5%) deaths and five (2.5%) with liver failure. Mortality was 4.88% in CLD and 3.14% in non-CLD subjects over median periods of 58 (8-106) days and 22 (1-65) days, respectively. Conclusions: In this liver disease registry, the causes, clinical presentation, and outcomes of DILI in subjects with CLD and without CLD patients were not different. Further study is required to confirm our findings.
