    A Comparative Analysis of Bleeding Peptic Ulcers in Hospitalizations With and Without End-Stage Renal Disease
    (Elmer Press, 2023) Dahiya, Dushyant Singh; Mandoorah, Sohaib; Gangwani, Manesh Kumar; Ali, Hassam; Merza, Nooraldin; Aziz, Muhammad; Singh, Amandeep; Perisetti, Abhilash; Garg, Rajat; Cheng, Chin-I; Dutta, Priyata; Inamdar, Sumant; Sanaka, Madhusudhan R.; Al-Haddad, Mohammad; Medicine, School of Medicine
    Background: End-stage renal disease (ESRD) patients are highly susceptible to peptic ulcer bleeding (PUB). We aimed to assess the influence of ESRD status on PUB hospitalizations in the United States (USA). Methods: We analyzed the National Inpatient Sample to identify all adult PUB hospitalizations in the USA from 2007 to 2014, which were divided into two subgroups based on the presence or absence of ESRD. Hospitalization characteristics and clinical outcomes were compared. Furthermore, predictors of inpatient mortality for PUB hospitalizations with ESRD were identified. Results: Between 2007 and 2014, there were 351,965 PUB hospitalizations with ESRD compared to 2,037,037 non-ESRD PUB hospitalizations. PUB ESRD hospitalizations had a higher mean age (71.6 vs. 63.6 years, P < 0.001), and proportion of ethnic minorities i.e., Blacks, Hispanics, and Asians compared to the non-ESRD cohort. We also noted higher all-cause inpatient mortality (5.4% vs. 2.6%, P < 0.001), rates of esophagogastroduodenoscopy (EGD) (20.7% vs. 19.1%, P < 0.001), and mean length of stay (LOS) (8.2 vs. 6 days, P < 0.001) for PUB ESRD hospitalizations compared to the non-ESRD cohort. After multivariate logistic regression analysis, Whites with ESRD had higher odds of mortality from PUB compared to Blacks. Furthermore, the odds of inpatient mortality from PUB decreased by 0.6% for every 1-year increase in age for hospitalizations with ESRD. Compared to the 2011 - 2014 study period, the 2007 - 2010 period had 43.7% higher odds (odds ratio (OR): 0.696, 95% confidence interval (CI): 0.645 - 0.751) of inpatient mortality for PUB hospitalizations with ESRD. Conclusions: PUB hospitalizations with ESRD had higher inpatient mortality, EGD utilization, and mean LOS compared to non-ESRD PUB hospitalizations.

    Acute pancreatitis in liver transplant hospitalizations: Identifying national trends, clinical outcomes and healthcare burden in the United States
    (Baishideng Publishing Group, 2023) Dahiya, Dushyant Singh; Jahagirdar, Vinay; Chandan, Saurabh; Gangwani, Manesh Kumar; Merza, Nooraldin; Ali, Hassam; Deliwala, Smit; Aziz, Muhammad; Ramai, Daryl; Pinnam, Bhanu Siva Mohan; Bapaye, Jay; Cheng, Chin-I; Inamdar, Sumant; Sharma, Neil R.; Al-Haddad, Mohammad; Medicine, School of Medicine
    Background: Acute pancreatitis (AP) in liver transplant (LT) recipients may lead to poor clinical outcomes and development of severe complications. Aim: We aimed to assess national trends, clinical outcomes, and the healthcare burden of LT hospitalizations with AP in the United States (US). Methods: The National Inpatient Sample was utilized to identify all adult (≥ 18 years old) LT hospitalizations with AP in the US from 2007-2019. Non-LT AP hospitalizations served as controls for comparative analysis. National trends of hospitalization characteristics, clinical outcomes, complications, and healthcare burden for LT hospitalizations with AP were highlighted. Hospitalization characteristics, clinical outcomes, complications, and healthcare burden were also compared between the LT and non-LT cohorts. Furthermore, predictors of inpatient mortality for LT hospitalizations with AP were identified. All P values ≤ 0.05 were considered statistically significant. Results: The total number of LT hospitalizations with AP increased from 305 in 2007 to 610 in 2019. There was a rising trend of Hispanic (16.5% in 2007 to 21.1% in 2018, P-trend = 0.0009) and Asian (4.3% in 2007 to 7.4% in 2019, p-trend = 0.0002) LT hospitalizations with AP, while a decline was noted for Blacks (11% in 2007 to 8.3% in 2019, P-trend = 0.0004). Furthermore, LT hospitalizations with AP had an increasing comorbidity burden as the Charlson Comorbidity Index (CCI) score ≥ 3 increased from 41.64% in 2007 to 62.30% in 2019 (P-trend < 0.0001). We did not find statistically significant trends in inpatient mortality, mean length of stay (LOS), and mean total healthcare charge (THC) for LT hospitalizations with AP despite rising trends of complications such as sepsis, acute kidney failure (AKF), acute respiratory failure (ARF), abdominal abscesses, portal vein thrombosis (PVT), and venous thromboembolism (VTE). Between 2007-2019, 6863 LT hospitalizations with AP were compared to 5649980 non-LT AP hospitalizations. LT hospitalizations with AP were slightly older (53.5 vs 52.6 years, P = 0.017) and had a higher proportion of patients with CCI ≥ 3 (51.5% vs 19.8%, P < 0.0001) compared to the non-LT cohort. Additionally, LT hospitalizations with AP had a higher proportion of Whites (67.9% vs 64.6%, P < 0.0001) and Asians (4% vs 2.3%, P < 0.0001), while the non-LT cohort had a higher proportion of Blacks and Hispanics. Interestingly, LT hospitalizations with AP had lower inpatient mortality (1.37% vs 2.16%, P = 0.0479) compared to the non-LT cohort despite having a higher mean age, CCI scores, and complications such as AKF, PVT, VTE, and the need for blood transfusion. However, LT hospitalizations with AP had a higher mean THC ($59596 vs $50466, P = 0.0429) than the non-LT cohort. Conclusion: In the US, LT hospitalizations with AP were on the rise, particularly for Hispanics and Asians. However, LT hospitalizations with AP had lower inpatient mortality compared to non-LT AP hospitalizations.

    Artificial Intelligence in Endoscopic Ultrasound for Pancreatic Cancer: Where Are We Now and What Does the Future Entail?
    (MDPI, 2022-12-16) Dahiya, Dushyant Singh; Al-Haddad, Mohammad; Chandan, Saurabh; Gangwani, Manesh Kumar; Aziz, Muhammad; Mohan, Babu P.; Ramai, Daryl; Canakis, Andrew; Bapaye, Jay; Sharma, Neil; Medicine, School of Medicine
    Pancreatic cancer is a highly lethal disease associated with significant morbidity and mortality. In the United States (US), the overall 5-year relative survival rate for pancreatic cancer during the 2012–2018 period was 11.5%. However, the cancer stage at diagnosis strongly influences relative survival in these patients. Per the National Cancer Institute (NCI) statistics for 2012–2018, the 5-year relative survival rate for patients with localized disease was 43.9%, while it was 3.1% for patients with distant metastasis. The poor survival rates are primarily due to the late development of clinical signs and symptoms. Hence, early diagnosis is critical in improving treatment outcomes. In recent years, artificial intelligence (AI) has gained immense popularity in gastroenterology. AI-assisted endoscopic ultrasound (EUS) models have been touted as a breakthrough in the early detection of pancreatic cancer. These models may also accurately differentiate pancreatic cancer from chronic pancreatitis and autoimmune pancreatitis, which mimics pancreatic cancer on radiological imaging. In this review, we detail the application of AI-assisted EUS models for pancreatic cancer detection. We also highlight the utility of AI-assisted EUS models in differentiating pancreatic cancer from radiological mimickers. Furthermore, we discuss the current limitations and future applications of AI technology in EUS for pancreatic cancers.

    Artificial intelligence in gastrointestinal endoscopy: a comprehensive review
    (Hellenic Society of Gastroenterology, 2024) Ali, Hassam; Muzammil, Muhammad Ali; Dahiya, Dushyant Singh; Ali, Farishta; Yasin, Shafay; Hanif, Waqar; Gangwani, Manesh Kumar; Aziz, Muhammad; Khalaf, Muhammad; Basuli, Debargha; Al-Haddad, Mohammad; Medicine, School of Medicine
    Integrating artificial intelligence (AI) into gastrointestinal (GI) endoscopy heralds a significant leap forward in managing GI disorders. AI-enabled applications, such as computer-aided detection and computer-aided diagnosis, have significantly advanced GI endoscopy, improving early detection, diagnosis and personalized treatment planning. AI algorithms have shown promise in the analysis of endoscopic data, critical in conditions with traditionally low diagnostic sensitivity, such as indeterminate biliary strictures and pancreatic cancer. Convolutional neural networks can markedly improve the diagnostic process when integrated with cholangioscopy or endoscopic ultrasound, especially in the detection of malignant biliary strictures and cholangiocarcinoma. AI's capacity to analyze complex image data and offer real-time feedback can streamline endoscopic procedures, reduce the need for invasive biopsies, and decrease associated adverse events. However, the clinical implementation of AI faces challenges, including data quality issues and the risk of overfitting, underscoring the need for further research and validation. As the technology matures, AI is poised to become an indispensable tool in the gastroenterologist's arsenal, necessitating the integration of robust, validated AI applications into routine clinical practice. Despite remarkable advances, challenges such as operator-dependent accuracy and the need for intricate examinations persist. This review delves into the transformative role of AI in enhancing endoscopic diagnostic accuracy, particularly highlighting its utility in the early detection and personalized treatment of GI diseases.

    Basic Principles and Role of Endoscopic Ultrasound in Diagnosis and Differentiation of Pancreatic Cancer from Other Pancreatic Lesions: A Comprehensive Review of Endoscopic Ultrasound for Pancreatic Cancer
    (MDPI, 2024-04-28) Dahiya, Dushyant Singh; Shah, Yash R.; Ali, Hassam; Chandan, Saurabh; Gangwani, Manesh Kumar; Canakis, Andrew; Ramai, Daryl; Hayat, Umar; Pinnam, Bhanu Siva Mohan; Iqbal, Amna; Malik, Sheza; Singh, Sahib; Jaber, Fouad; Alsakarneh, Saqr; Mohamed, Islam; Ali, Meer Akbar; Al-Haddad, Mohammad; Inamdar, Sumant; Medicine, School of Medicine
    Pancreatic cancer is one of the leading causes of cancer-related deaths worldwide. Pancreatic lesions consist of both neoplastic and non-neoplastic lesions and often pose a diagnostic and therapeutic challenge due to similar clinical and radiological features. In recent years, pancreatic lesions have been discovered more frequently as incidental findings due to the increased utilization and widespread availability of abdominal cross-sectional imaging. Therefore, it becomes imperative to establish an early and appropriate diagnosis with meticulous differentiation in an attempt to balance unnecessary treatment of benign pancreatic lesions and missing the opportunity for early intervention in malignant lesions. Endoscopic ultrasound (EUS) has become an important diagnostic modality for the identification and risk stratification of pancreatic lesions due to its ability to provide detailed imaging and acquisition of tissue samples for analysis with the help of fine-needle aspiration/biopsy. The recent development of EUS-based technology, including contrast-enhanced endoscopic ultrasound, real-time elastography–endoscopic ultrasound, miniature probe ultrasound, confocal laser endomicroscopy, and the application of artificial intelligence has significantly augmented the diagnostic accuracy of EUS as it enables better evaluation of the number, location, dimension, wall thickness, and contents of these lesions. This article provides a comprehensive overview of the role of the different types of EUS available for the diagnosis and differentiation of pancreatic cancer from other pancreatic lesions while discussing their key strengths and important limitations.

    Clinical characteristics and outcomes of autoimmune pancreatitis based on serum immunoglobulin G4 levels: A single-center, retrospective cohort study
    (Baishideng, 2023) Jaber, Fouad; Elfert, Khaled; Alsakarneh, Saqr; Beran, Azizullah; Jaber, Mohammed; Gangwani, Manesh Kumar; Abboud, Yazan; Medicine, School of Medicine
    Autoimmune pancreatitis (AIP) is a complex, poorly understood disease gaining increasing attention. "Clinical Characteristics and Outcome of AIP Based on Serum IgG4 levels," investigated AIP with a focus on serum immunoglobulin (Ig) G4 levels. The 213 patients with AIP were classified according to serum IgG4 levels: Abnormal (elevated) and normal. Patients with higher IgG4 levels exhibited a more active immune system and increased relapse rates. Beyond IgG4, the IgA levels and age independently contributed to relapse risk, guiding risk assessment and tailored treatments for better outcomes. However, limitations persist, such as no IgA correlation with IgG4 levels, absent data on autoantibody-positive AIP cases critical for Asian diagnostic criteria, and unexplored relapse rates in high serum IgG AIP by subtype. Genetic factors and family histories were not addressed. As the understanding and referral of seronegative AIPs increase, there's a growing need for commercially available, highly sensitive, and specific autoantibodies to aid in diagnosing individuals with low or absent serum IgG4 levels.

    Clinical Outcomes and Complications for Achalasia Patients Admitted After Per-Oral Endoscopic Myotomy
    (Elmer Press, 2023) Dahiya, Dushyant Singh; Nivedita, Fnu; Perisetti, Abhilash; Goyal, Hemant; Inamdar, Sumant; Gangwani, Manesh Kumar; Aziz, Muhammad; Ali, Hassam; Cheng, Chin-I; Sanaka, Madhusudhan R.; Al-Haddad, Mohammad; Sharma, Neil R.; Medicine, School of Medicine
    Background: Per-oral endoscopic myotomy (POEM) is a rapidly emerging minimally invasive procedure for management of achalasia. Same-day discharge after POEM is safe and feasible; however, some patients may need hospitalization. We aimed to identify characteristics and outcomes for achalasia patients requiring hospitalizations after POEM in the United States (US). Methods: The US National Inpatient Sample was utilized to identify all adult achalasia patients who were admitted after POEM from 2016 to 2019. Hospitalization characteristics and clinical outcomes were highlighted. Results: From 2016 to 2019, we found that 1,885 achalasia patients were admitted after POEM. There was an increase in the total number of hospitalizations after POEM from 380 in 2016 to 490 in 2019. The mean age increased from 54.2 years in 2016 to 59.3 years in 2019. Most POEM-related hospitalizations were for the 65 - 79 age group (31.8%), females (50.4%), and Whites (68.4%). A majority (56.2%) of the study population had a Charlson Comorbidity Index of 0. The Northeast hospital region had the highest number of POEM-related hospitalizations. Most of these patients (88.3%) were eventually discharged home. There was no inpatient mortality. The mean length of stay decreased from 4 days in 2016 to 3.2 days in 2019, while the mean total healthcare charge increased from $52,057 in 2016 to $65,109 in 2019. Esophageal perforation was the most common complication seen in 1.3% of patients. Conclusion: The number of achalasia patients needing hospitalization after POEM increased. There was no inpatient mortality conferring an excellent safety profile of this procedure.

    Early and Late Readmissions of Radiation Proctitis in the United States: Are We Getting Better?
    (MDPI, 2024-01-12) Dahiya, Dushyant Singh; Pinnam, Bhanu Siva Mohan; Ishaya, Michelle; Chandan, Saurabh; Gangwani, Manesh Kumar; Singh, Sahib; Ali, Hassam; Sohail, Amir Humza; Canakis, Andrew; Ramai, Daryl; Zelt, Christina; Inamdar, Sumant; Al-Haddad, Mohammad; Rojas-DeLeon, Mariajose; Sharma, Neil R.; Medicine, School of Medicine
    Background/Aims: Radiation proctitis (RP), a well-known complication of pelvic radiation therapy, may lead to recurrent hospitalizations. We aimed to assess readmissions of RP in the United States. Methods: We analyzed the Nationwide Readmission Database from 2016 to 2020 to identify all 30-, 60-, and 90-day readmissions of RP in the United States. Hospitalization characteristics, predictors, clinical outcomes, and healthcare burdens were assessed. Results: From 2016 to 2020, we noted a declining trend of 30-, 60-, and 90-day readmissions of RP in the US. However, the all-cause 30-, 60-, and 90-day readmission rates of RP were still high at 13.7%, 19.4%, and 23.16%, respectively. On readmission, RP was identified as the admitting diagnosis in only 20.61%, 17.87%, and 15.76% of 30-, 60-, and 90-day readmissions, respectively. The mean age for all readmissions was 70 years with a significant male dominance. Lower endoscopy at index admission reduced the risk of readmissions within 90 days, but this was not statistically significant. However, the Charlson Comorbidity Index (CCI) score was an independent predictor of all readmissions. Furthermore, the mean length of stay was 5.57 (95% CI 5.15-6), 5.50 (95% CI 5.12-5.89), and 5.47 (95% CI 5.07-5.87) days and the mean hospitalization charge was USD 60,451 (95% CI USD 54,728-66,174), USD 62,671 (95% CI USD 57,326-68,015), and USD 62,144 (95% CI USD 57,144-67,144) for 30-, 60-, and 90-day readmissions. The all-cause inpatient mortality for 30-, 60-, and 90-day readmissions was 3.58%, 3.89%, and 3.46%, respectively. Conclusions: RP readmissions are a significant healthcare burden. Further efforts must be directed toward improving management strategies to reduce readmission rates.

    Efficacy of Dietary Interventions for Irritable Bowel Syndrome: A Systematic Review and Network Meta-Analysis
    (MDPI, 2024-12-11) Haghbin, Hossein; Hasan, Fariha; Gangwani, Manesh Kumar; Zakirkhodjaev, Nurruddinkhodja; Lee-Smith, Wade; Beran, Azizullah; Kamal, Faisal; Hart, Benjamin; Aziz, Muhammad; Medicine, School of Medicine
    Introduction: Irritable bowel syndrome (IBS) is a common condition that alters the quality of life of patients. A variety of dietary interventions have been introduced to address this debilitating condition. The low-FODMAP diet (LFD), gluten-free diet (GFD), and Mediterranean diet are examples showing efficacy. The aim of this network meta-analysis was to compare these interventions to find the best approach. Methods: We performed a systematic review of the available literature through 14 March 2024 in the following databases: Embase, PubMed, MEDLINE OVID, Web of Science, CINAHL Plus, and Cochrane Central. We only included randomized controlled trials (RCTs). We used a random effects model and conducted a direct meta-analysis based on the DerSimonian-Laird approach and a network meta-analysis based on the frequentist approach. Mean differences (MDs) with 95% confidence interval (CI) were calculated. The primary outcomes included IBS quality of life (IBS QOL) and IBS symptom severity scale (IBS-SSS). Results: We finalized 23 studies including 1689 IBS patients. In the direct meta-analysis, there was no statistically significant difference in any IBS score between GFD and either LFD or standard diet. Meanwhile, the LFD was statistically superior to the standard diet in the IBS-SSS (MD: -46.29, CI: -63.72--28.86, p < 0.01) and IBS QOL (MD: 4.06, CI: 0.72-7.41, p = 0.02). On ranking, the Mediterranean diet showed the greatest improvement in IBS-SSS, IBS-QOL, distension, dissatisfaction, and general life interference, followed by the LFD alone or in combination with the GFD. Conclusions: We demonstrated the efficacy of dietary interventions such as the LFD and Mediterranean diet in improving IBS. There is a need for large RCTs with head-to-head comparisons, particularly for the Mediterranean diet.

    Peptic ulcer disease in non-alcoholic fatty liver disease hospitalizations: A new challenge on the horizon in the United States
    (Baishideng, 2023) Dahiya, Dushyant Singh; Jahagirdar, Vinay; Ali, Hassam; Gangwani, Manesh Kumar; Aziz, Muhammad; Chandan, Saurabh; Singh, Amandeep; Perisetti, Abhilash; Soni, Aakriti; Inamdar, Sumant; Sanaka, Madhusudhan R.; Al-Haddad, Mohammad; Medicine, School of Medicine
    Background: Peptic ulcer disease (PUD) is frequently seen in patients with liver cirrhosis. However, current literature lacks data on PUD in non-alcoholic fatty liver disease (NAFLD) hospitalizations. Aim: To identify trends and clinical outcomes of PUD in NAFLD hospitalizations in the United States. Methods: The National Inpatient Sample was utilized to identify all adult (≥ 18 years old) NAFLD hospitalizations with PUD in the United States from 2009-2019. Hospitalization trends and outcomes were highlighted. Furthermore, a control group of adult PUD hospitalizations without NAFLD was also identified for a comparative analysis to assess the influence of NAFLD on PUD. Results: The total number of NAFLD hospitalizations with PUD increased from 3745 in 2009 to 3805 in 2019. We noted an increase in the mean age for the study population from 56 years in 2009 to 63 years in 2019 (P < 0.001). Racial differences were also prevalent as NAFLD hospitalizations with PUD increased for Whites and Hispanics, while a decline was observed for Blacks and Asians. The all-cause inpatient mortality for NAFLD hospitalizations with PUD increased from 2% in 2009 to 5% in 2019 (P < 0.001). However, rates of Helicobacter pylori (H. pylori) infection and upper endoscopy decreased from 5% in 2009 to 1% in 2019 (P < 0.001) and from 60% in 2009 to 19% in 2019 (P < 0.001), respectively. Interestingly, despite a significantly higher comorbidity burden, we observed lower inpatient mortality (2% vs 3%, P = 0.0004), mean length of stay (LOS) (11.6 vs 12.1 d, P < 0.001), and mean total healthcare cost (THC) ($178598 vs $184727, P < 0.001) for NAFLD hospitalizations with PUD compared to non-NAFLD PUD hospitalizations. Perforation of the gastrointestinal tract, coagulopathy, alcohol abuse, malnutrition, and fluid and electrolyte disorders were identified to be independent predictors of inpatient mortality for NAFLD hospitalizations with PUD. Conclusion: Inpatient mortality for NAFLD hospitalizations with PUD increased for the study period. However, there was a significant decline in the rates of H. pylori infection and upper endoscopy for NAFLD hospitalizations with PUD. After a comparative analysis, NAFLD hospitalizations with PUD had lower inpatient mortality, mean LOS, and mean THC compared to the non-NAFLD cohort.
