RESUMO
OBJECTIVE: Drug sustainability (DS), a surrogate marker for drug efficacy, is important, especially when aiming for precision medicine. However, it lacks reliable prediction methods. AIMS: To develop and externally validate a web-based artificial intelligence(AI)-derived tool for predicting DS of infliximab and vedolizumab in patients with moderate-to-severe Ulcerative Colitis (UC). METHODS: Data from three Israeli centers included infliximab or vedolizumab patients treated for >54 weeks. Sustainability meant no corticosteroids, hospitalizations or surgeries. Machine learning techniques predicted >54-week and overall DS using baseline clinical data. RESULTS: The model was developed using data from 246 patients from Rabin Medical Center and externally validated on 67 patients from Rambam Health Care Campus and Sheba Medical Center. No significant difference in DS was observed across the datasets. Most patients were biologic-naïve and primarily treated with vedolizumab. The model performed well, with an area under the ROC curve of 0.86, and showed good accuracy (65.5 %-76.9 %) across the test sets. CONCLUSIONS: The study introduces a novel, AI-based tool for predicting >54-week DS of infliximab and vedolizumab in moderate-to-severe UC, using baseline parameters. This can aid clinical decision-making in the framework of precision medicine, promising to optimize disease management while maintaining physician autonomy.
RESUMO
Background and study aims Rising prevalence of pancreatic cysts and inconsistent management guidelines necessitate innovative approaches. New features of large language models (LLMs), namely custom GPT creation, provided by ChatGPT can be utilized to integrate multiple guidelines and settle inconsistencies. Methods A custom GPT was developed to provide guideline-based management advice for pancreatic cysts. Sixty clinical scenarios were evaluated by both the custom GPT and gastroenterology experts. A consensus was reached between experts and review of guidelines and the accuracy of recommendations provided by the custom GPT was evaluated and compared with experts. Results The custom GPT aligned with expert recommendations in 87% of scenarios. Initial expert recommendations were correct in 97% and 87% of cases, respectively. No significant difference was observed between the accuracy of custom GPT and the experts. Agreement analysis using Cohen's and Fleiss' Kappa coefficients indicated consistency among experts and the custom GPT. Conclusions This proof-of-concept study shows the custom GPT's potential to provide accurate, guideline-based recommendations for pancreatic cyst management, comparable to expert opinions. The study highlights the role of advanced features of LLMs in enhancing clinical decision-making in fields with significant practice variability.
RESUMO
BACKGROUND: Society guidelines on colorectal dysplasia screening, surveillance, and endoscopic management in inflammatory bowel disease (IBD) are complex, and physician adherence to them is suboptimal. We aimed to evaluate the use of ChatGPT, a large language model, in generating accurate guideline-based recommendations for colorectal dysplasia screening, surveillance, and endoscopic management in IBD in line with European Crohn's and Colitis Organization (ECCO) guidelines. METHODS: 30 clinical scenarios in the form of free text were prepared and presented to three separate sessions of ChatGPT and to eight gastroenterologists (four IBD specialists and four non-IBD gastroenterologists). Two additional IBD specialists subsequently assessed all responses provided by ChatGPT and the eight gastroenterologists, judging their accuracy according to ECCO guidelines. RESULTS: ChatGPT had a mean correct response rate of 87.8%. Among the eight gastroenterologists, the mean correct response rates were 85.8% for IBD experts and 89.2% for non-IBD experts. No statistically significant differences in accuracy were observed between ChatGPT and all gastroenterologists (P=0.95), or between ChatGPT and the IBD experts and non-IBD expert gastroenterologists, respectively (P=0.82). CONCLUSIONS: This study highlights the potential of language models in enhancing guideline adherence regarding colorectal dysplasia in IBD. Further investigation of additional resources and prospective evaluation in real-world settings are warranted.
RESUMO
BACKGROUND: Abnormal phosphate levels are associated with adverse outcomes in critical illness. However, there is scarce evidence on phosphate's impact on acute pancreatitis outcomes, and the few studies examining this subject are relatively small and show conflicting data. We sought to determine the association between phosphate level at admission and the clinical course and outcomes of acute pancreatitis. METHODS: In this retrospective single-center observational study, we included all adult patients admitted with a primary diagnosis of acute pancreatitis between January 2008 and June 2021. Phosphate levels at admission were classified as normal (2.8-4.5 mg/dl), low (below 2.8 mg/dl), or high (above 4.5 mg/dl). RESULTS: Out of 2308 cases, 1868 patients had documented phosphate levels at admission and were thus included in our final analysis. 1096 (59%) had normal phosphate levels, 686 (37%) had hypophosphatemia, and 86 (4.6%) had hyperphosphatemia on admission. 30-day mortality rates were 3.4%, 3.8%, and 19% in normal, low, and high phosphate levels, respectively. In univariate analysis, hyperphosphatemia was significantly associated with 30-day mortality, with an OR of 6.54 (95% CI 3.39-12.2, p < 0.001; AUC = 0.58). In a multivariate analysis adjusting for age, MAP, GFR, BUN, and pH, hyperphosphatemia remained a statistically significant independent predictor of early mortality (OR-2.93, 95% CI 1.28-6.51, p = 0.009). Hypophosphatemia was not significantly associated with 30-day mortality in univariate analysis, OR of 1.13 (95% CI 0.67-1.87, p = 0.6). CONCLUSION: Hyperphosphatemia at admission was independently associated with increased 30-day mortality in patients with acute pancreatitis. Hypophosphatemia at admission was not significantly associated with 30-day mortality.
RESUMO
BACKGROUND AND AIMS: ChatGPT, an advanced language model, is increasingly used in diverse fields, including medicine. This study explores using ChatGPT to optimize postcolonoscopy management by providing guideline-based recommendations and addressing low compliance rates and timing issues. METHODS: In this proof-of-concept study, 20 clinical scenarios were prepared as structured reports and free-text notes, and ChatGPT's responses were evaluated by 2 senior gastroenterologists. Compliance with guidelines and accuracy were assessed, and inter-rater agreement was calculated using Fleiss' kappa coefficient. RESULTS: ChatGPT exhibited 90% compliance with guidelines and 85% accuracy, with a very good inter-rater agreement (Fleiss' kappa coefficient of .84, P < .01). ChatGPT handled multiple variations and descriptions and crafted concise patient letters. CONCLUSIONS: Results suggest that ChatGPT could aid healthcare providers in making informed decisions and improve compliance with postcolonoscopy surveillance guidelines. Future research should investigate integrating ChatGPT into electronic health record systems and evaluating its effectiveness in different healthcare settings and populations.

BACKGROUND: Different antibiotic classes were reported to have variable effects on immunogenicity towards anti-tumour necrosis factor [TNF] agents. However, the impact of antibiotic administration on biologic treatment durability was not investigated. We aimed to assess the association between antibiotic treatment and persistence of different classes of biologic therapy in inflammatory bowel disease [IBD] patients. METHODS: Data from the epi-IIRN, a nationwide registry of all Israeli IBD patients were analysed. All patients who filled a prescription of either infliximab, adalimumab, vedolizumab, or ustekinumab, were included. Treatment cessation was defined as drug discontinuation of at least 6 months. Macrolides, cephalosporins, fluoroquinolones, and penicillins with beta-lactamase inhibitors were selected as primary exposure variables. Survival analysis was performed using marginal structural models for each drug separately. RESULTS: In all 13 513 IBD patients, with a total of 39 600 patient-years, were included. Significant differences of overall treatment persistence were demonstrated, with highest persistence rates for ustekinumab and the lowest for infliximab treatment. Macrolides were found to be significantly associated with reduced risk of infliximab cessation (adjusted hazard ratio [aHR] 0.72, 95% CI 0.62-0.89]. Fluoroquinolones and cephalosporins were associated with an elevated risk of adalimumab treatment cessation [aHR 1.33, 95% CI 1.22-1.46; and aHR 1.20, 95% CI 1.08-1.34, respectively]. No significant effects of the studied antibiotics were observed in ustekinumab and vedolizumab users. CONCLUSIONS: Specific antibiotic classes are associated with duration of anti-TNF treatment, but not with durability of vedolizumab or ustekinumab treatments. Further research is required to study the effect of specific antibiotics on response to biologics.
RESUMO
BACKGROUND: Current guidelines for the treatment of heart failure with reduced ejection fraction (HFrEF) are based on studies that have excluded or underrepresented older patients. OBJECTIVES: To assess the value of guideline directed medical therapy (GDMT) in HFrEF patients 80 years of age and older. METHODS: A single-center retrospective study included patients hospitalized with a first and primary diagnosis of acute decompensated heart failure (ADHF) and ejection fraction (EF) of ≤ 40%. Patients 80 years of age and older were stratified into two groups: GDMT, defined as treatment at hospital discharge with at least two drugs of the following groups: beta-blockers, angiotensin converting enzyme inhibitor (ACEI), angiotensin receptor blocker (ARB), or mineralocorticoid antagonists; and a personalized medicine group, which included patients who were treated with up to one of these drug groups. The primary outcomes were 90-day all-cause mortality, 90-day rehospitalization, and 3-years mortality. RESULTS: The study included 1152 patients with HFrEF. 254 (22%) patients who were at least 80 years old. Of the group, 123 were GDMT at discharge. When GDMT group was compared to the personalized medicine group, there were no statistically significant differences in terms 90-day mortality (17% vs. 13%, P = 0.169), 90-day readmission (51 % vs. 45.6%, P = 0.27), or 3-year mortality (64.5% vs. 63.3%, P = 0.915). CONCLUSIONS: Adherence to guidelines in the older adult population may not have the same effect as in younger patients who were studied in the randomized clinical trials. Larger prospective studies are needed to further address this issue.

OBJECTIVES: Basic science studies suggest that opioids aggravate disease severity and outcomes in acute pancreatitis. We sought to determine the association of opioid use and opioid type with the clinical course and outcome of acute pancreatitis. METHODS: In this retrospective single-center observational study, we included all adult patients admitted with acute pancreatitis between 2008 and 2021. Patients were classified into 3 groups based on analgesia type: morphine, noonmorphine opioid, and nonopioid. RESULTS: We included 2308 patients. Of the patients, 343 (14.9%) were treated with morphine, 733 (31.8%) were treated with nonmorphine opioids, and 1232 (53.4%) patients were in the nonopioid group. The incidence of 30-day mortality did not differ significantly between study groups: 3.9%, 2.9%, and 4.4% in the nonopioid, nonmorphine-opioid, and morphine groups, respectively ( P = 0.366).In multivariate analysis, the composite end point consisting of 30-day mortality, invasive ventilation, emergent abdominal surgery, and need for vasopressors was significantly more likely to occur in the morphine group than in the nonopioid group (adjusted odds ratio, 1.69; 95% confidence interval, 1.1-2.598; P = 0.01). CONCLUSIONS: Mortality among acute pancreatitis patients did not differ significantly between patients receiving morphine, nonmorphine opioids, and nonopioids. However, morphine treatment was associated with higher rates of some serious adverse events.

AIMS: The effect of elevated heart rate (HR) on morbidity and mortality is evident in chronic stable heart failure; data in this regard in acute decompensated heart failure (ADHF) setting are scarce. In this single-centre study, we sought to address the prognostic value of HR and beta-blocker dosage at discharge on all-cause mortality among patients with heart failure and reduced ejection fraction and ADHF. METHODS AND RESULTS: In this retrospective observational study, 2945 patients were admitted for the first time with the primary diagnosis of ADHF between January 2008 and February 2018. Patients were divided by resting HR at discharge into three groups (HR < 70 b.p.m., HR 70-90 b.p.m., and HR > 90 b.p.m.). Evidence-based beta-blockers were defined as metoprolol, bisoprolol, and carvedilol. The doses of prescribed beta-blockers were calculated into a percentage target dose of each beta-blocker and divided to four quartiles: 0 < Dose ≤ 25%, 25% < Dose ≤ 50%, 50% < Dose ≤ 75%, and >75% of the target dose. Cox regression was used to calculate the hazard ratio for various HR categories and adjusting for clinical and laboratory variables. At discharge, 1226 patients had an HR < 70 b.p.m., 1347 patients had an HR at range 70-90 b.p.m., and 372 patients with an HR > 90 b.p.m. The 30 day mortality rate was 2.2%, 3.7%, and 12.1% (P < 0.001), respectively. Concordantly, 1 year mortality rate was 14.6%, 16.7%, and 30.4% (P < 0.001) among patients with HR < 70 b.p.m., HR 70-90 b.p.m., and HR > 90 b.p.m., respectively. The adjusted hazard ratio was significantly increased only in HR above 90 b.p.m. category (hazard ratio, 2.318; 95% confidence interval, 1.794-2.996). CONCLUSIONS: Patients with ADHF and an HR of <90 b.p.m. at discharge had significantly a lower 1 year mortality independent of the dosage of beta-blocker at discharge. It is conceivable to discharge these patients with lower HR.

Fluoroquinolone prophylaxis during allogeneic hematopoietic stem cell transplantation (allo-HSCT) reduces bloodstream infections. However, this practice affects the gut microbiome and potentially increases dysbiosis, which is closely related to transplantation outcomes, and lower gastrointestinal (GI) tract acute graft-versus-host disease (GVHD). This study assessed the impact of omitting ciprofloxacin prophylaxis on GI GVHD, clinical outcomes, and microbiome composition in patients undergoing allo-HSCT. In this single-center, retrospective study comprising recipients of allo-HSCT performed between 2018 and 2020, routine ciprofloxacin prophylaxis (the exposure variable) was stopped in December 2018. The primary outcome was acute lower GI GVHD within 100 days post-transplantation; secondary outcomes were 1-year overall survival, nonrelapse mortality, relapse, and overall acute GVHD. Outcomes were compared using univariate and multivariate analyses and Kaplan-Meier/competing-risk analyses. Sequential stool samples were collected prospectively from a subpopulation of recipients, and the microbiome composition was analyzed. Seventy-five of the 129 patients (58.1%) received prophylactic ciprofloxacin treatment. Baseline characteristics did not differ between the 2 study groups: patients with ciprofloxacin prophylaxis and those without ciprofloxacin prophylaxis. The rate of lower GI GVHD also did not differ between the 2 groups (24% versus 18.5%; P = .597). None of the secondary outcomes was significantly different between the 2 groups in univariate, multivariate, and time-to-event analyses. In addition, microbiome analysis in a subpopulation of 22 patients did not reveal any significant between-group difference in alpha or beta diversity. Omitting prophylactic ciprofloxacin during allo-HSCT did not affect microbiome composition, lower GI-GVHD rate, or other significant clinical outcomes. The use of prophylactic antibiotics in this setting should be evaluated further.

BACKGROUND: An association between paroxysmal supraventricular tachycardias (PSVT) and elevated cardiac troponin I (cTnI) has been reported in small studies, even in the absence of significant coronary artery or structural heart disease. We sought to explore the prognostic significance of elevated cTnI among patients presenting with PSVT. METHODS: This is a retrospective single-center observational study conducted between January 2014 and Decemebr 2016. 165 patients (60% men, mean age 55 ± 17 year-old) with an acute episode of regular supraventricular tachyarrhythmia were admitted to the emergency department at Rambam Medical Center. 131 patients had at least one serum cTnI value measured. Of those, 57 had a positive result, defined as serum cTnI of more than 0.028 ng/dL. RESULTS: Multivariate analysis showed that heart rate > 150 beats per minute (bpm) on admission (OR = 3.9; 95% CI 1.1.6-9.5; p < 0.003) and history of coronary artery disease (CAD) (OR = 3.4; 95% CI 1.2-10.1; p = 0.026) were the only independent predictors of cTnI elevation. After mean follow-up period of 23 ± 7 months, the combined primary outcome of death, coronary intervention (PCI) or myocardial infarction (MI) occurred in 7 patients (12.3%) out of 57 patients with positive cTnI and in zero patients with negative cTn (p = 0.002). Cox proportional hazard model showed that elevated cTnI on admission was an independent predictor of adverse outcomes only in patients with known coronary artery disease (CAD) (HR = 3.3, p = 0.05). CONCLUSION: Elevated cTnI among patients presenting with PSVT appears to have prognostic significance only in patients with history of CAD. In this patient group elevated cTnI is associated with increased risk of adverse cardiac outcomes. We therefore believe serum cTnI should be measured selectively, such as in patients with symptoms of ischemic chest pain and a high pretest likelihood of having CAD.

AIM: Due to conflicting data, we aimed to investigate the association of inflammatory bowel disease (IBD) with cardiovascular disease (CVD) risk factors at late adolescence in a cross-sectional population-based study. METHODS: A total of 1 144 213 Jewish Israeli adolescents who underwent a general health examination prior to enlistment at median age of 17.1 years from 1988 to 2016 were included. Covariate data included demographics, blood pressure, resting heart rate and risk factors associated with CVD. RESULTS: Overall, 2372 cases of IBD were identified, including 1612 cases of Crohn's disease (68%). Univariate analysis showed marginally lower systolic and diastolic blood pressure in patients with IBD with no difference following multivariate analysis. Diagnosis of Crohn's disease in males was associated with lower rates of overweight (15.8% vs 21.2%, P < .001) and obesity (3.7% vs 6.1% P = .003), whereas females with Crohn's disease had a lower rate of overweight (14.0% vs 17.9% P = .04) but not obesity. Patients with ulcerative colitis did not differ from controls in terms of overweight or obesity. Patients with Crohn's disease had an increased prevalence of hereditary hypercoagulability (odds ratio 16.9, 95% confidence interval 8.0-35.7, P < .001). CONCLUSION: Significant risk factors for CVD were not present in adolescents with IBD.

BACKGROUND: Inflammatory bowel diseases are associated with various immune- and non-immune-mediated conditions. We aimed to assess the association of inflammatory bowel diseases with comorbidities at late adolescence. METHODS: Jewish Israeli adolescents who underwent a general health evaluation prior to enlistment to the Israeli Defense Forces from 2002 to 2016 were included. RESULTS: Overall, 891 subjects (595 Crohn's disease, 296 ulcerative colitis, median age 17.1 years) and 1,141,841 controls were analyzed. Crohn's disease was associated with arthritis (odds ratio (OR) 4.7, 95% confidence interval (CI) 2.4-9.1), thyroid disease (OR 2.6, 95% CI 1.2-5.5), atopic dermatitis (OR 2, 95% CI 1.1-3.6), autoimmune hepatitis (OR 4.4, 95% CI 2.3-8.6), nephrolithiasis (OR 3.6, 95% CI 1.2-11.4), and pancreatitis (OR 41.8, 95% CI 17.2-101.9). Ulcerative colitis was associated with arthritis (OR 3.6, 95% CI 1.0-9.8), thyroid disease (OR 4.8, 95% CI 1.2-19.4), autoimmune hepatitis (OR 8, 95% CI 4-16.2), and pancreatitis (OR 51, 95% CI 16.1-158.9). Primary sclerosing cholangitis was associated with both diseases. Asthma, celiac, type 1 diabetes, psoriasis, and bone fractures were not more common in both diseases. Male predominance was noted for most associations. CONCLUSIONS: At adolescence, both Crohn's disease and ulcerative colitis are associated with multiple comorbidities, not limited to autoimmune disorders.

BACKGROUND: The incidence and prevalence trends of inflammatory bowel disease (IBD) vary between developed and developing countries. AIM: To investigate the prevalence and associated sociodemographic factors of IBD in Israeli Jewish adolescents METHODS: The files of the army medical corps were reviewed for adolescents recruited in 2002-2016 with confirmed IBD. Covariate data included birth date, patient and parental country of birth, number of children in the household, age at diagnosis, and socioeconomic status. Findings were compared with the remaining recruits without IBD. RESULTS: Of the 1,144,213 adolescents recruited, 2372 (0.2%) had IBD (Crohn's disease, 68%). Median age of the cohort was 17.1 years (interquartile range, 16.9-17.3). Over the study period, the annual point prevalence per 100,000 examinees significantly increased: total IBD, 58 to 373; Crohn's disease, 42 to 425; ulcerative colitis, 16 to 128. Mean age at IBD diagnosis decreased from 15.0 ± 2.8 years in 2002-2008 to 14.3 ± 3.1 years in 2009-2016 (P < 0.0001). Significance was maintained on separate analyses of Crohn's disease and ulcerative colitis. Both diseases were significantly less prevalent in subjects from families with at least one parent born in a developing country and ≥3 children. There was a significant association of lower socioeconomic status with lower prevalence of Crohn's disease (odds ratio 0.41, 95% confidence interval, 0.31-0.54) and ulcerative colitis (odds ratio 0.25, 95% confidence interval, 0.15-0.42). CONCLUSIONS: The point prevalence of Crohn's disease and ulcerative colitis in Israeli Jewish adolescents increased six-fold and eight-fold, respectively, over 15 years along with a decrease in age at diagnosis.

BACKGROUND: Growth impairment is common in pediatric inflammatory bowel disease (IBD) patients. Nevertheless, a controversy exists regarding disease impact on anthropometric measures in the long term. Thus, we aimed to investigate the impact of IBD on anthropometric measures, including weight, height, and body mass index (BMI), during late adolescence in a cross-sectional, population-based study. METHODS: A total of 1,144,213 Jewish Israeli adolescents who underwent a general health examination from 2002 to 2016 at a median age (interquartile range) of 17.1 (16.9-17.3) years were included. Inflammatory bowel disease cases were stratified into Crohn's disease (CD) and ulcerative colitis (UC). Patients were also subgrouped based on age at IBD diagnosis. RESULTS: Overall, 2372 cases of IBD were identified out of 1,144,213 persons examined (0.2%). Crohn's disease accounted for 68% of IBD cases. Males and females with CD (but not with UC) had significantly lower weight and BMI compared with controls. Differences in height at late adolescence were not statistically significant for either disease compared with controls (females: 162 cm vs 161.7 cm vs 161.5 cm; males: 174 cm vs 173.7 cm vs 173.6 cm for controls, UC, and CD, respectively). In a subgroup analysis, patients with CD diagnosed at age <14 years were significantly shorter than controls (males: 172.7 cm vs 174 cm; P = 0.001; females: 160.6 cm vs 162; P = 0.008). This pattern was not noted in UC patients. CONCLUSIONS: Adolescents with CD were leaner compared with the general population. No overall difference was noted in height at late adolescence. Younger age at diagnosis was associated with reduced height in CD patients.

Background Gastric cancer occurs mainly in older patients, with a peak incidence over 60 years of age. It is relatively rare among younger individuals. However, the frequency of gastric cancer in young patients appears to be on the rise worldwide. Case presentation We report the case of a 19-year-old female soldier who, after a considerable diagnostic delay, was diagnosed with gastric adenocarcinoma. She is one of the youngest gastric adenocarcinoma patients ever reported in Israel. Conclusion This case should serve as a reminder that gastric carcinoma is a possible diagnosis even in young patients. It also highlights the critical importance of obtaining a thorough medical history in the process of clinical decision making.
RESUMO
OBJECTIVES: Hypertrophic cardiomyopathy (HCM) is characterized by diastolic dysfunction, which is difficult to assess by noninvasive methods. We hypothesized that measurement of simultaneous left ventricular (LV) and left atrial (LA) volume changes by cardiac computed tomography would be useful in the assessment of diastolic function in HCM. METHODS: We studied 21 patients with HCM and 21 age-matched controls. The LA and LV volumes were calculated and early and late diastolic volume changes derived. RESULTS: The HCM patients had significantly larger LA volumes and reduced LA total emptying fraction (30 ± 7% vs 42 ± 6%; P < 0.0001). Conduit volume was increased (30 ± 6 vs 22 ± 4 mL/m; P < 0.0001) and contributed a significantly higher proportion of total LV diastolic filling, suggesting that passive filling of the LV compensates for LA dysfunction, but at the expense of increased pulmonary filling pressure. CONCLUSIONS: This study suggests that simultaneous depiction of computed tomography-derived LV and LA volume changes can characterize diastolic dysfunction in HCM.
