    (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.

    (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.

    (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.

    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.
