    (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.

    (Hellenic Society of Gastroenterology, 2022) Dahiya, Dushyant Singh; Al-Haddad, Mohammad; Perisetti, Abhilash; Singh, Amandeep; Goyal, Hemant; Cheng, Chin-I; Garg, Rajat; Pisipati, Sailaja; Ameyi, Justice; Sanaka, Madhusudhan R.; Inamdar, Sumant; Medicine, School of Medicine
    Background: This study aimed to assess the trends and characteristics of celiac disease (CeD) hospitalizations in the United States (US). Methods: The National Inpatient Sample was analyzed from 2007-2017 to identify all adult hospitalizations with a primary discharge diagnosis of CeD. Demographic trends, associations, and other aspects of CeD hospitalizations were analyzed. SAS 9.4 was used for statistical analysis and P-values ≤0.05 were considered statistically significant. Results: From 2007-2017, we noted an increasing trend of CeD hospitalizations from 19,385 in 2007 to 38,395 in 2017 (P-trend <0.001). The mean age was 57.85 years, with a declining trend. Females and patients with a Charlson Comorbidity Index score ≥3 had a rising trend of CeD hospitalizations from 70.68% in 2007 to 73% in 2017 (P-trend <0.001) and from 16.96% in 2007 to 26.59% in 2017 (P-trend <0.001), respectively. Additionally, a White predominance was seen in the study cohort. Furthermore, for CeD hospitalizations, all-cause inpatient mortality increased from 1.30% in 2007 to 1.58% in 2017 (P-trend <0.001) and the mean total hospital charge increased from $26,299 in 2007 to $49,282 in 2017 (P-trend <0.001). However, we noted a decline in the mean length of stay (LOS) from 4.88 days in 2007 to 4.59 days in 2017 (P-trend=0.0015) and rates of esophagogastroduodenoscopy performed from 2.09% in 2007 to 1.89% in 2017 (P-trend <0.001). Conclusion: We noted a rising trend in hospitalizations, inpatient mortality, and hospital costs for CeD hospitalizations in the US; however, inpatient EGDs performed and mean LOS showed a decline.

    Developing Intelligent Negotiation System
    (Office of the Vice Chancellor for Research, 2015-04-17) Singh, Amandeep; Dhaliwal, GaganPal Singh; Dudani, Raviraj; Patil, Suyog; Hossain, Gahangir
    Abstract Negotiation has become an important aspect of our daily lives. Humans negotiate over a phone, face to face meeting and verbal and non-verbal activities. With the advent of intelligence system research, the requirement of efficient negotiation system became a prime issue. It has a number of applications including collaborating cyber human interaction, e-commerce negotiation and intelligent shared behavior study. Adapting game theory of mind concept in intelligent negotiation protocol implementation may make the future cyber system robust, social and adaptive. Keeping in mind the user’s policies and an intention to gain the maximum profit, we introduced the hybrid negotiation system to make a system robust and more useful. User’s intention to gain the maximum profit is considered important to figure out the opponent’s policies so that the system can make a right automatic decision. Based on our initial literature review, game theory of mind can be a good choice in sub-optimal intelligent negotiation system design. Therefore, a system based on game theory of mind is under design process that is being evaluated on Yahoo marketing data set.

    Endoscopic versus surgical management for colonic volvulus hospitalizations in the United States
    (Korean Society of Gastrointestinal Endoscopy, 2023) Dahiya, Dushyant Singh; Perisetti, Abhilash; Goyal, Hemant; Inamdar, Sumant; Singh, Amandeep; Garg, Rajat; Cheng, Chin-I; Al-Haddad, Mohammad; Sanaka, Madhusudhan R.; Sharma, Neil; Medicine, School of Medicine
    Background/aims: Colonic volvulus (CV), a common cause of bowel obstruction, often requires intervention. We aimed to identify hospitalization trends and CV outcomes in the United States. Methods: We used the National Inpatient Sample to identify all adult CV hospitalizations in the United States from 2007 to 2017. Patient demographics, comorbidities, and inpatient outcomes were highlighted. Outcomes of endoscopic and surgical management were compared. Results: From 2007 to 2017, there were 220,666 CV hospitalizations. CV-related hospitalizations increased from 17,888 in 2007 to 21,715 in 2017 (p=0.001). However, inpatient mortality decreased from 7.6% in 2007 to 6.2% in 2017 (p<0.001). Of all CV-related hospitalizations, 13,745 underwent endoscopic intervention, and 77,157 underwent surgery. Although the endoscopic cohort had patients with a higher Charlson comorbidity index, we noted lower inpatient mortality (6.1% vs. 7.0%, p<0.001), mean length of stay (8.3 vs. 11.8 days, p<0.001), and mean total healthcare charge ($68,126 vs. $106,703, p<0.001) compared to the surgical cohort. Male sex, increased Charlson comorbidity index scores, acute kidney injury, and malnutrition were associated with higher odds of inpatient mortality in patients with CV who underwent endoscopic management. Conclusion: Endoscopic intervention has lower inpatient mortality and is an excellent alternative to surgery for appropriately selected CV hospitalizations.

    Increasing thirty-day readmissions of Crohn's disease and ulcerative colitis in the United States: A national dilemma
    (Baishideng Publishing Group, 2022) Dahiya, Dushyant Singh; Perisetti, Abhilash; Kichloo, Asim; Singh, Amandeep; Goyal, Hemant; Rotundo, Laura; Vennikandam, Madhu; Shaka, Hafeez; Singh, Gurdeep; Singh, Jagmeet; Pisipati, Sailaja; Al-Haddad, Mohammad; Sanaka, Madhusudhan R.; Inamdar, Sumant; Medicine, School of Medicine
    Background: The prevalence of Crohn's disease (CD) and ulcerative colitis (UC) is on the rise worldwide. This rising prevalence is concerning as patients with CD and UC may frequently relapse leading to recurrent hospitalizations and increased healthcare utilization. Aim: To identify trends and adverse outcomes for 30 d readmissions for CD and UC. Methods: This was a retrospective, interrupted trends study involving all adult (≥ 18 years) 30 d readmissions of CD and UC from the National Readmission Database (NRD) between 2008 and 2018. Patients < 18 years, elective, and traumatic hospitalizations were excluded from this study. We identified hospitalization characteristics and readmission rates for each calendar year. Trends of inpatient mortality, mean length of hospital stay (LOS) and mean total hospital cost (THC) were calculated using a multivariate logistic trend analysis adjusting for age, gender, insurance status, comorbidity burden and hospital factors. Furthermore, trends between CD and UC readmissions were compared using regression of the interaction coefficient after adjusting for age and gender to determine relative trends between the two populations. Stata® Version 16 software (StataCorp, TX, United States) was used for statistical analysis and P value ≤ 0.05 were considered statistically significant. Results: Total number of 30 d readmissions increased from 6202 in 2010 to 7672 in 2018 for CD and from 3272 in 2010 to 4234 in 2018 for UC. We noted increasing trends for 30-day all-cause readmission rate of CD from 14.9% in 2010 to 17.6% in 2018 (P-trend < 0.001), CD specific readmission rate from 7.1% in 2010 to 8.2% in 2018 (P-trend < 0.001), 30-day all-cause readmission rate of UC from 14.1% in 2010 to 15.7% in 2018 (P-trend = 0.003), and UC specific readmission rate from 5.2% in 2010 to 5.6% in 2018 (P-trend = 0.029). There was no change in the risk adjusted trends of inpatient mortality and mean LOS for CD and UC readmissions. However, we found an increasing trend of mean THC for UC readmissions. After comparison, there was no statistical difference in the trends for 30 d all-cause readmission rate, inpatient mortality, and mean LOS between CD and UC readmissions. Conclusion: There was an increase in total number of 30 d readmissions for CD and UC with a trend towards increasing 30 d all-cause readmission rates.

    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.

    The Conundrum of Obesity and Gastroparesis Hospitalizations: A Retrospective Comparative Analysis of Hospitalization Characteristics and Disparities Amongst Socioeconomic and Racial Backgrounds in the United States
    (The Korean Society of Neurogastroenterology and Motility, 2022) Dahiya, Dushyant S.; Inamdar, Sumant; Perisetti, Abhilash; Goyal, Hemant; Singh, Amandeep; Garg, Rajat; Cheng, Chin-I; Kichloo, Asim; Al-Haddad, Mohammad; Sharma, Neil; Medicine, School of Medicine
    Background/aims: We aim to assess the influence of obesity on gastroparesis (GP) hospitalizations in the United States (US). Methods: The National Inpatient Sample was analyzed from 2007-2017 to identify all adult hospitalizations with a primary discharge diagnosis of GP. They were subdivided based on the presence or absence of obesity (body mass index > 30). Hospitalization characteristics, procedural differences, all-cause inpatient mortality, mean length of stay (LOS), and mean total hospital charge (THC) were identified and compared. Results: From 2007-2017, there were 140 293 obese GP hospitalizations accounting for 13.75% of all GP hospitalizations in the US. Obese GP hospitalizations were predominantly female (76.11% vs 64.36%, P < 0.001) and slightly older (51.9 years vs 50.8 years, P < 0.001) compared to the non-obese cohort. Racial disparities were noted as Blacks (25.49% vs 22%, P < 0.001) had higher proportions of GP hospitalizations with obesity compared to the non-obese cohort. Furthermore, we noted higher rates of inpatient upper endoscopy utilization (6.05% vs 5.42%, P < 0.001), longer mean LOS (5.71 days vs 5.32 days, P < 0.001), and higher mean THC ($53 373 vs $45 040, P < 0.001) for obese GP hospitalizations compared to the non-obese group. However, obese GP hospitalizations had lower rates of inpatient mortality (0.92% vs 1.33%, P < 0.001), and need for nutritional support with endoscopic jejunostomy (0.25 vs 0.56%, P < 0.001) and total parenteral nutrition (1.46% vs 2.33%, P < 0.001) compared to the non-obese cohort. Conclusions: In the US, compared to non-obese, a higher proportion of obese GP hospitalizations were female and Blacks. Obese GP hospitalizations also had higher THC, LOS, and rates of upper endoscopy.
