The cost implications of Wilson disease among hospitalized patients: analysis of USA hospitals.

BACKGROUND AND AIM: In this study, we used a national cohort of patients with Wilson's disease (WD) to investigate the admissions, mortality rates, and costs over the captured period to assess specific subpopulations at higher burden. METHODS: Patients with WD were selected using 2016-2019 National Inpatient Sample (NIS). The weighted estimates and patient data were stratified using demographics and medical characteristics. Regression curves were graphed to derive goodness-of-fit for each trend from which R2 and P values were calculated. RESULTS: Annual total admissions per 100 000 hospitalizations due to WD were 1075, 1180, 1140, and 1330 ( R2  = 0.75; P  = 0.13) from 2016 to 2019. Within the demographics, there was an increase in admissions among patients greater than 65 years of age ( R2  = 0.90; P  = 0.05) and White patients ( R2  = 0.97; P  = 0.02). Assessing WD-related mortality rates, there was an increase in the mortality rate among those in the first quartile of income ( R2  = 1.00; P  < 0.001). The total cost for WD-related hospitalizations was $20.90, $27.23, $24.20, and $27.25 million US dollars for the years 2016, 2017, 2018, and 2019, respectively ( R2  = 0.47; P  = 0.32). There was an increasing total cost trend for Asian or Pacific Islander patients ( R2  = 0.90; P  = 0.05). Interestingly, patients with cirrhosis demonstrated a decreased trend in the total costs ( R2  = 0.97; P  = 0.02). CONCLUSION: Our study demonstrated that certain ethnicity groups, income classes and comorbidities had increased admissions or costs among patients admitted with WD.

Inpatient Cost Burdens of Treating Chronic Hepatitis B in US Hospitals: A Weighted Analysis of a National Database.

BACKGROUND AND AIMS: This study evaluates the cost burdens of inpatient care for chronic hepatitis B (CHB). We aimed to stratify the patients based on the presence of cirrhosis and conduct subgroup analyses on patient demographics and medical characteristics. METHODS: The 2016-2019 National Inpatient Sample was used to select individuals diagnosed with CHB. The weighted charge estimates were derived and converted to admission costs, adjusting for inflation to the year 2016, and presented in United States Dollars. These adjusted values were stratified using select patient variables. To assess the goodness-of-fit for each trend, we graphed the data across the respective years, expressed in a chronological sequence with format (R2, p-value). Analysis of CHB patients was carried out in three groups: the composite CHB population, the subset of patients with cirrhosis, and the subset of patients without cirrhosis. RESULTS: From 2016 to 2019, the total costs of hospitalizations in CHB patients were $603.82, $737.92, $758.29, and $809.01 million dollars from 2016 to 2019, respectively. We did not observe significant cost trends in the composite CHB population or in the cirrhosis and non-cirrhosis cohorts. However, we did find rising costs associated with age older than 65 (0.97, 0.02), white race (0.98, 0.01), Hispanic ethnicity (1.00, 0.001), and Medicare coverage (0.95, 0.02), the significance of which persisted regardless of the presence of cirrhosis. Additionally, inpatients without cirrhosis who had comorbid metabolic dysfunction-associated steatotic liver disease (MASLD) were also observed to have rising costs (0.96, 0.02). CONCLUSIONS: We did not find a significant increase in overall costs with CHB inpatients, regardless of the presence of cirrhosis. However, certain groups are more susceptible to escalating costs. Therefore, increased screening and nuanced vaccination planning must be optimized in order to prevent and mitigate these growing cost burdens on vulnerable populations.

The impact of macro- and micro-steatosis on the outcomes of patients who undergo liver transplant: Analysis of the UNOS-STAR database.

BACKGROUND AND AIMS: The presence of steatosis in a donor liver and its relation to post-transplantation outcomes are not well defined. This study evaluates the effect of the presence and severity of micro- and macro-steatosis of a donor graft on post-transplantation outcomes. METHODS: The UNOS-STAR registry (2005-2019) was used to select patients who received a liver transplant graft with hepatic steatosis. The study cohort was stratified by the presence of macro- or micro-vesicular steatosis, and further stratified by histologic grade of steatosis. The primary endpoints of all-cause mortality and graft failure were compared using sequential Cox regression analysis. Analysis of specific causes of mortality was further performed. RESULTS: There were 9184 with no macro-steatosis (control), 150 with grade 3 macro-steatosis, 822 with grade 2 macro-steatosis and 12 585 with grade 1 macro-steatosis. There were 10 320 without micro-steatosis (control), 478 with grade 3 micro-steatosis, 1539 with grade 2 micro-steatosis and 10 404 with grade 1 micro-steatosis. There was no significant difference in all-cause mortality or graft failure among recipients who received a donor organ with any evidence of macro- or micro-steatosis, compared to those receiving non-steatotic grafts. There was increased mortality due to cardiac arrest among recipients of a grade 2 macro-steatosis donor organ. CONCLUSION: This study shows no significant difference in all-cause mortality or graft failure among recipients who received a donor liver with any degree of micro- or macro-steatosis. Further analysis identified increased mortality due to specific aetiologies among recipients receiving donor organs with varying grades of macro- and micro-steatosis.

The role of donor sex on the post-liver transplant outcomes in patients with primary sclerosing cholangitis.

BACKGROUND AND AIMS: Primary sclerosing cholangitis (PSC) can result in hepatic decompensation and require liver transplantation (LT). This study investigates the effect of the sex of the donor and recipient as a prognostic risk factor for adverse outcomes after LT in patients with PSC. METHODS: UNOS registry was used to select LT patients with PSC from 1987 to 2019. The study cohort was stratified based on the sex of the recipient and further subdivided based on the sex of the donor. The primary endpoints of this study were all-cause mortality and graft failure, which were evaluated using a sequential Cox regression analysis. RESULTS: This study included 2829 patients; 906 female recipients were transplanted from 441 male donors and 465 female donors. 1923 male recipients were transplanted from 1194 male donors and 729 female donors. Within the mismatch analyses, the male-to-male recipients also had a significantly reduced hazard ratio of graft failure compared to female-to-male transplants [aHR 0.51, 95% confidence interval (CI) 0.33-0.79, P  = 0.003]. No difference in graft failure was observed in the mismatched female recipient subgroup. The mismatched male recipient group also showed a decreased hazard ratio of mortality from graft rejection and respiratory causes. No differences in specific mortality causes were identified in the mismatched female recipient group. CONCLUSION: This study demonstrated an increase in the risk of graft failure and mortality secondary to graft failure in male recipients of female donor livers. No differences in mortality or graft failure were identified in female recipients of male livers.

Active narcotic use and post-peroral endoscopic myotomy outcomes in esophageal motility disorders.

BACKGROUND AND AIMS: Peroral endoscopic myotomy (POEM) is a minimally invasive technique used to treat esophageal motility disorders. Opioid use has been demonstrated to adversely affect esophageal dysmotility and is associated with an increased prevalence of esophageal motility disorders. Our aim was to investigate the effect of narcotic use on success rates in patients undergoing POEM. METHODS: This was a single-center, retrospective study of patients undergoing POEM between February 2017 and September 2021. Primary outcomes were post-POEM Eckardt score (ES), distensibility index, and length of procedure. Secondary outcomes included technical success, myotomy length, length of stay, adverse events, reintervention rates, and postprocedure GERD. RESULTS: During the study period, 90 patients underwent POEM for treatment of esophageal dysmotility disorders. Age, sex, race, indications for POEM, and body mass index were not significant between those with or without narcotic use. There were no differences in procedure time, preprocedure ESs, or length of stay. Postprocedure ESs were higher in the group with active narcotic use compared to the group with no prior history (2.73 vs 1.2, P = .004). Distensibility indexes measured with EndoFLIP (Medtronic, Minneapolis, Minn, USA) were not different in patients using narcotics compared with opioid-naïve patients. CONCLUSION: Active narcotic use negatively affects symptom improvement after POEM for the treatment of esophageal motility disorders.

Trends of Costs and Admission Rates Among Patients Admitted With Autoimmune Hepatitis: Analysis of US Hospitals Using the NIS Database.

Background and aim: Autoimmune hepatitis (AIH) is a prominent cause of chronic liver disease in the United States. This study aims to characterize the incidence, mortality, and cost implications of this condition using a national database. Method: The 2016-2019 National Inpatient Sample was used to select patients with AIH. After adjusting for inflation, weighted charge data were used to calculate the admission costs using charge-to-cost ratios. Demographic, socioeconomic status, and comorbidity values were used to build strata to characterize admission incidence, mortality data and aggregate and per-capita cost values. Furthermore, additional sensitivity analysis was performed using a stratified set of patients with AIH as one of the top 10 diagnosis (AIH-specific subsample). Multinomial regression curves were graphed and assessed to derive goodness-of-fit for each trend. R2 and P-values were calculated. Results: From 2016 to 2019, the total admissions related to AIH were approximately 20,984, 21,905, 22,055, and 22,680 cases, respectively (R2: 0.93, P-value: 0.03). AIH-related hospitalization aggregate costs came to $338.18, $369.17, $355.98, and $387.25 million dollars (R2: 0.75, P-value: 0.17). Significant admission growth was seen in the Southern region (R2: 0.91, P-value: 0.05). Most notably, increasing trends in total admissions were found across older age, those of White and Hispanic descent, and those with comorbidities. On the other hand, the AIH-specific subsample illustrated decreasing trends in admissions across demographics (i.e., age, gender, and race) and comorbidities; however, those with hepatic complications saw a rise in the admission trends (cirrhosis - R2: 0.98, P-value: 0.009; multiple liver complications - R2: 0.95, P-value: 0.03). Conclusion: Among AIH-specific admissions, there was a decreasing trend overall; however, there was an exceptional increase in the admissions among those with hepatic complications.

Anesthesia Choice and Its Potential Impact on Endoluminal Functional Lumen Imaging Probe Measurements in Esophageal Motility Disorders.

BACKGROUND AND AIMS: The widespread use of peroral endoscopic myotomy (POEM) has revolutionized the management of esophageal motility disorders (EMDs). The introduction of an endoluminal functional lumen imaging probe (EndoFLIP) can serve as a complimentary diagnostic tool to assess the mechanical properties (i.e., pressure, diameter, distensibility and topography) of the esophagus. During EndoFLIP measurements, different anesthesia techniques may induce variable degrees of neuromuscular blockade, potentially affecting esophageal motility and altering the results of EndoFLIP metrics. Our study aimed to compare the impact of using total intravenous anesthesia (TIVA) versus general anesthesia with inhalational anesthetics (GAIA) on diagnostic EndoFLIP measurements. METHODS: We conducted a retrospective study of all adult patients (≥18 years) undergoing EndoFlip during the POEM procedure at our institution between February 2017 and February 2022. We obtained the differences in pressure, diameter, and distensibility index using propofol-based TIVA vs sevoflurane-based GAIA with a 30ml and 60ml balloon. The differences were divided into terciles and compared between diagnoses using univariate comparisons and logistic regression models. RESULTS: 49 patients were included (39% Type 1 achalasia, 43% Type 2 or 3 achalasia, and 18% jackhammer esophagus (JE)). Compared to spastic disorders (Type 2, 3 and JE), Type 1 had lower values of pressure differences at 60 mL in univariate (3.75 vs 15.20 p=0.001) and multivariate (aOR 0.89 95%CI 0.82-0.978) analyses. Compared to Type 1, Type 2 and 3 had higher rates of pressure differences at 60 mL in univariate (9.85 vs 3.75 p=0.04); and nearly reached significance in multivariate analysis (1.09 95%CI 1-1.20). Compared to Type 1, JE demonstrated higher values in pressure differences at 60 mL (27.7 vs 3.75 p<0.001) CONCLUSION: Esophageal pressure, as measured by EndoFLIP, was significantly reduced when patients were sedated with sevoflurane-based GAIA. The use sevoflurane-based GAIA for diagnostic EndoFLIP may potentially lead to the misclassification of spastic disorders as Type I achalasia. Therefore, propofol-based TIVA should be considered over sevoflurane-based GAIA for sedation during the diagnostic test.

The Impact of Race and Sex on the Clinical Outcomes of Homeless Patients With Alcoholic Liver Disease: Propensity Score Matched Analysis of US Hospitals.

BACKGROUND: Among patients with alcoholic liver disease (ALD), homelessness poses significant medical and psychosocial risks; however, less is known about the effects of race and sex on the hospital outcomes of admitted homeless patients with ALD. METHODS: The National Inpatient Sample database from 2012 to 2017 was used to isolate homeless patients with ALD, and the cohort was further stratified by race and sex for comparisons. Propensity score matching was utilized to minimize covariate confounding. The primary endpoints of this study include mortality, hospital length of stay, and hospital costs; secondary endpoints included the incidence of liver complications. RESULTS: There were 3972 females/males postmatch, as well as 2224 Blacks/Whites and 4575 Hispanics/Whites postmatch. In multivariate, there were no significant differences observed in mortality rate, length of stay, and costs between sexes. Comparing liver outcomes, females had a higher incidence of hepatic encephalopathy [adjusted odds ratio (aOR) 1.02, 95% CI: 1.01-1.04, P<0.001]. In comparing Blacks versus Whites, Black patients had higher hospitalization costs (aOR 1.13, 95% CI: 1.03-1.24, P=0.01); however, there were no significant differences in mortality, length of stay, or liver complications. In comparing Hispanics versus Whites, Hispanic patients had longer length of hospital stay (aOR 1.12, 95% CI: 1.06-1.19, P<0.001), greater costs (aOR 1.15, 95% CI: 1.09-1.22, P<0.001), as well as higher prevalence of liver complications including varices (aOR 1.04, 95% CI: 1.02-1.06, P<0.001), hepatic encephalopathy (aOR 1.03, 95% CI: 1.02-1.04, P<0.001), and hepatorenal syndrome (aOR 1.01, 95% CI 1.00-1.01, P=0.03). However, there was no difference in mortality between White and Hispanic patients. CONCLUSIONS: Black and Hispanic ALD patients experiencing homelessness were found to incur higher hospital charges; furthermore, Hispanic patients also had greater length of stay and higher incidence of liver-related complications compared with White counterparts.

The Trends in Health Care Utilization and Costs Associated With Primary Liver Cancer: An Analysis of United States Hospitals Between 2016 and 2019.

BACKGROUND: Primary liver cancer (PLC) has placed an increasing economic and resource burden on the health care system of the United States. We attempted to quantify its epidemiology and associated costs using a national inpatient database. METHODS: Hospital discharge and insurance claims data from the National Inpatient Sample were used to conduct this analysis. Patients diagnosed with PLC (hepatocellular carcinoma or cholangiocarcinoma) were included in the study population, which was then stratified using patient demographics, comorbidities, degree of cancer spread, liver disease complications, and other descriptors. Trends were analyzed via regression curves for each of these strata from the years 2016 to 2019, with special attention to patterns in hospitalization incidence, inpatient mortality rate, total costs, and average per-capita costs. The resulting curves were evaluated using goodness-of-fit statistics and P-values. RESULTS: Aggregate hospitalization incidence, inpatient mortality rates, and total costs were found to significantly increase throughout the study period (P=0.002, 0.002, and 0.02, respectively). Relative to their demographic counterparts, males, White Americans, and those older than 65 years of age contributed the largest proportions of total costs. These population segments also experienced significant increases in total expenditure (P=0.04, 0.03, and 0.02, respectively). Admissions deemed to have multiple comorbidities were associated with progressively higher total costs throughout the study period (P=0.01). Of the categorized underlying liver diseases, only admissions diagnosed with alcoholic liver disease or nonalcoholic fatty liver disease saw significantly increasing total costs (P=0.006 and 0.01), although hepatitis C was found to be the largest contributor to total expenses. CONCLUSIONS: From 2016 to 2019, total costs, admission incidence, and inpatient mortality rates associated with PLC hospitalization increased. Strata-specific findings may be reflective of demographic shifts in the PLC patient populations, as well as changes in underlying chronic liver disease etiologies.

Health care leaders' perspectives on the business impact of mobile health clinics.

BACKGROUND: By analyzing how health care leaders in the United States view mobile health programs and their impact on the organization's bottom line, this study equips those who currently operate or plan to deploy mobile clinics with a business case framework. Our aim is to understand health care leaders' perspectives about business-related incentives and disincentives for mobile healthcare. METHODS: We conducted 25 semi-structured key informant interviews with U.S. health care leaders to explore their views and experiences related to mobile health care. We used deductive and inductive thematic analysis to identify patterns in the data. An advisory group with expertise in mobile health, health management, and health care finance informed data collection and analysis. RESULTS: In addition to improving health outcomes, mobile clinics can bolster business objectives of health care organizations including those related to budget, business strategy, organizational culture, and health equity. We created a conceptual framework that demonstrates how these factors, supported by community engagement and data, come together to form a business case for mobile health care. DISCUSSION: Our study demonstrates that mobile clinics can contribute to health care organizations' business goals by aligning with broader organizational strategies. The conceptual model provides a guide for aligning mobile clinics' work with business priorities of organizations and funders. CONCLUSIONS: By understanding how health care leaders reconcile the business pressures they face with opportunities to advance health equity using mobile clinics, we can better support the strategic and sustainable expansion of the mobile health sector.

The impact of race and gender on the outcomes of patients with acetaminophen-induced acute liver failure: propensity score-matched analysis of the NIS database.

BACKGROUND: Acetaminophen overdose is one of the leading causes of acute liver failure in the USA. In this study, we investigated the impact of race and gender on the hospital outcomes of patients admitted with acetaminophen-induced acute liver failure. METHODS: From the National Inpatient Sample between the years 2016 and 2019, patients with acetaminophen-induced acute liver failure were selected and stratified based on gender (Male and Female) and race (White, Black and Hispanic). The cases were propensity score-matched to controls (male and Whites) and were compared along the following endpoints: mortality, length of stay, hospitalization costs, and hepatic complications. RESULTS: Among patients with acetaminophen-induced acute liver failure, females experienced higher rates of mortality (16.60% vs. 11.70%, P = 0.004) and clinical illness, including hypotension (11.80% vs. 7.15%, P = 0.002) and ventilator use (40.80% vs. 30.00%, P < 0.001). When stratified by race, Black patients had longer hospital stays (Black vs. White, 8.76 days vs. 7.46 days, P = 0.03). There were no significant differences in outcomes between Hispanic and White patients. No significant differences in mortality were shown between races. CONCLUSION: We found that females had a higher rate of mortality and incidence of hepatic encephalopathy compared to males. When stratified by race, Blacks were shown to have longer hospital stay. Females and racial minorities were also affected by special healthcare needs after discharge compared to their male and White cohorts, respectively.

Impact of Inflammatory Bowel Disease Subtypes on the Post-liver Transplant Outcomes of Patients with Primary Sclerosing Cholangitis.

BACKGROUND AND AIMS: Liver transplant patients with primary sclerosing cholangitis often present with concurrent inflammatory bowel disease. The effect of comorbid conditions on post-transplant prognosis was evaluated. METHODS: The 2005-2019 United Network of Organ Sharing Standard Transplant Analysis and Research database was used to identify patients with primary sclerosing cholangitis. Patients were categorized as having Crohn's Disease, ulcerative colitis, unclassified inflammatory bowel disease, or no inflammatory bowel disease. Baseline characteristics were assessed between cohorts, and outcomes were examined using Cox regression. Outcomes included all-cause mortality, graft failure, infection-induced mortality, and organ system-delineated mortality. Supplementary analyses with unique exclusion and stratification criteria were also performed. RESULTS: Among 2829 patients undergoing transplant, 1360 were considered to have ulcerative colitis, 372 were considered to have Crohn's Disease, and 69 were considered to have an unclassified form of inflammatory bowel disease. Primary sclerosing cholangitis patients with some form of inflammatory bowel disease had no increased risk for any outcomes. However, patients with ulcerative colitis had lower risks of general infectious (aHR 0.65 95%CI 0.44-0.95) and sepsis-induced (aHR 0.56 95%CI 0.35-0.91) mortality, whereas patients with Crohn's Disease had higher risks of sepsis-induced mortality (aHR 2.13 95%CI 1.22-3.70). Supplementary analyses showed effect modification by abdominal surgery history and era. CONCLUSION: The type of inflammatory bowel disease in liver transplant patients with primary sclerosing cholangitis was found to portend risk difference for infection-induced mortality, with ulcerative colitis found to be protective and Crohn's Disease predictive of increased mortality secondary to infectious etiologies. These associations warrant further investigation.

The causes of death in patients with nonalcoholic steatohepatitis following liver transplantation stratified using pre-liver transplant BMI.

BACKGROUND & AIMS: Determining the effects of pre-liver transplant (LT) BMI independent of underlying ascites on the post-LT outcomes of patients with nonalcoholic steatohepatitis (NASH) is needed to clarify the paradoxical and protective effects of obesity on post-LT endpoints. In order to accomplish this, we used graded severities of ascites to stratify the NASH-LT population and to perform an ascites-specific strata analysis with differing pre-LT BMI levels. METHODS: 2005-2019 United Network for Organ Sharing (UNOS) Standard Transplant Analysis and Research (STAR) database was queried to select patients with NASH, who were categorized into specific sets of ascites severity: no ascites (n = 1188), mild ascites (n = 4463), and moderate ascites (n = 3525). Then, BMI classification (underweight: < 18.5, normal: 18.5-25, overweight: 25-30, obese: ≥ 30 kg/m2) was used to stratify each ascites-specific group and to compare to the post-LT mortality endpoints. Those under 18 years old and those who received living/multi-organ transplants were excluded. RESULTS: Among each ascites category, there were the following numbers of normal, underweight, overweight, and obese BMI patients respectively; no ascites: 161, 4, 359, 664; mild ascites: 643, 28, 1311, 2481; and moderate ascites: 529, 25, 1030, 1941. The obese BMI cohort was at a lower risk of all-cause mortality compared to recipients with normal BMI with mild ascites (aHR: 0.79, 95% Confidence Interval (CI) 0.65-0.94, p-value = 0.010; case-incidence 47.10 vs 56.81 deaths per 1000 person-years) and moderate ascites (aHR: 0.77, 95% CI 0.63-0.94, p-value = 0.009; case-incidence 53.71 vs 66.17 deaths per 1000 person-years). In addition, the overweight BMI cohort with mild ascites demonstrated a lower hazard of all-cause mortality (aHR: 0.80, 95% CI 0.66-0.97, p-value = 0.03; case-incidence 49.09 vs 56.81 deaths per 1000 person-years). There was no difference in graft failure for the three BMI groups (underweight, overweight, and obese) in comparison to normal BMI. Furthermore, the overweight BMI group with mild ascites cohort demonstrated a lower hazard of death due to general infectious causes (aHR: 0.51, 95% CI 0.32-0.83, p = 0.006; case-incidence 6.12 vs 11.91 deaths per 1000 person-years) and sepsis (aHR: 0.49, 95% CI 0.27-0.86, p = 0.01; case-incidence 4.31 vs 8.50 deaths per 1000 person-years). CONCLUSION: The paradoxical effects of obesity in reducing the risks of all-cause death appears to be in part modulated by ascites. The current study emphasizes the need to evaluate BMI with concomitant ascites severity pre-LT to accurately prognosticate post-LT outcomes when evaluating NASH patients with advanced liver disease.

Benefits of EUS-guided gastroenterostomy over surgical gastrojejunostomy in the palliation of malignant gastric outlet obstruction: a large multicenter experience.

BACKGROUND AND AIMS: Palliation of malignant gastric outlet obstruction (mGOO) allows resumption of peroral intake. Although surgical gastrojejunostomy (SGJ) provides durable relief, it may be associated with a higher morbidity, interfere with chemotherapy, and require an optimum nutritional status. EUS-guided gastroenterostomy (EUS-GE) has emerged as a minimally invasive alternative. We aimed to conduct the largest comparative series to date between EUS-GE and SGJ for mGOO. METHODS: This multicenter retrospective study included consecutive patients undergoing SGJ or EUS-GE at 6 centers. Primary outcomes included time to resumption of oral intake, length of stay (LOS), and mortality. Secondary outcomes included technical and clinical success, reintervention rates, adverse events (AEs), and resumption of chemotherapy. RESULTS: A total of 310 patients were included (EUS-GE, n = 187; SGJ, n = 123). EUS-GE exhibited significantly lower time to resumption of oral intake (1.40 vs 4.06 days, P < .001), at lower albumin levels (2.95 vs 3.33 g/dL, P < .001), and a shorter LOS (5.31 vs 8.54 days, P < .001) compared with SGJ; there was no difference in mortality (48.1% vs 50.4%, P = .78). Technical (97.9% and 100%) and clinical (94.1% vs 94.3%) success was similar in the EUS-GE and SGJ groups, respectively. EUS-GE had lower rates of AEs (13.4% vs 33.3%, P < .001) but higher reintervention rates (15.5% vs 1.63%, P < .001). EUS-GE patients exhibited significantly lower interval time to resumption of chemotherapy (16.6 vs 37.8 days, P < .001). Outcomes between the EUS-GE and laparoscopic (n = 46) surgical approach showed that EUS-GE had shorter interval time to initiation/resumption of oral intake (3.49 vs 1.46 days, P < .001), decreased LOS (9 vs 5.31 days, P < .001), and a lower rate of AEs (11.9% vs 17.9%, P = .003). CONCLUSIONS: This is the largest study to date showing that EUS-GE can be performed among nutritionally deficient patients without affecting the technical and clinical success compared with SGJ. EUS-GE is associated with fewer AEs while allowing earlier resumption of diet and chemotherapy.

The impact of recipient and donor gender-match and mismatch on the post-liver transplant outcomes of patients with primary biliary cholangitis.

BACKGROUND & AIMS: In this study, we evaluate the effects of donor gender on post-liver transplant (LT) prognosis. We specifically consider patients with primary biliary cholangitis (PBC). METHODS: The 2005 to 2019 UNOS transplant registry was used to select patients with PBC. The study cohort was stratified by donor gender. All-cause mortality and graft failure hazards were compared using iterative Cox regression analysis. Subanalyses were performed to evaluate gender mismatch on post-LT prognosis. RESULTS: There were 1885 patients with PBC. Of these cases, 965 entries had male donors and 920 had female donors. Median follow-up was 4.82 (25-75% IQR 1.83-8.93) years. Having a male donor was associated with higher all-cause mortality (aHR 1.28 95%CI 1.03-1.58) and graft failure (aHR 1.70 95%CI 1.02-2.82). Corresponding incidence rates were also relatively increased. In the sub-analysis of female recipients (n = 1581), those with gender-mismatch (male donors, n = 769) were associated with higher all-cause mortality (aHR 1.41 95%CI 1.11-1.78) but not graft failure. In the male recipient subanalysis (n = 304), no associations were found between gender-mismatch (female donors, n = 108) and all-cause mortality or graft failure. CONCLUSION: This study shows that recipients who have male donors experienced higher rates of all-cause mortality following LT. This finding was consistent in the female recipient-male donor mismatch cohort.

Comparing clinical success and procedural difficulty between treatment-naïve and treatment-refractory patients with esophageal motility disorders during peroral endoscopic myotomy.

BACKGROUND AND AIMS: Peroral endoscopic myotomy (POEM) can successfully treat patients with achalasia. Prior therapy with Botox (Allergan, Madison, NJ, USA) injections, pneumatic dilation (PD), and/or laparoscopic Heller myotomy (LHM) is believed to increase the difficulty of POEM procedures. We aimed to determine if prior treatment methods were associated with longer procedure times or lower clinical success. METHODS: In this single-center retrospective study, consecutive patients who underwent POEM for achalasia between February 2017 and September 2021 were studied. Collected data were patient demographics, prior treatment, pre- and postprocedure Eckardt score (ES), distensibility indices (DIs), and procedure times. Primary outcomes were clinical success and procedure difficulty. RESULTS: Of 95 patients (mean age, 55.6 years; 45% women), 25 patients underwent POEM for type I achalasia, 31 for type II achalasia, and 33 for spastic esophageal pathologies. Thirty-three patients (34.7%) were treated for achalasia before POEM with onabotulinumtoxinA injections (n = 18), PD (n = 17), and LHM (n = 3). There were no significant differences in post-treatment ESs or technical success between the 2 groups (P = .98 and P = .66, respectively). Multivariate analysis showed that prior treatment was associated with decreased case time and easier tunneling during POEM. CONCLUSIONS: Prior treatment did not impact the clinical success rate of POEM and led to decreased case times and easier tunneling difficulty, likely because of persistent lower esophageal sphincter changes and differences in diagnostic indications. POEM should be considered for patients with treatment-refractory symptoms as a safe and feasible option. Further large-scale studies are needed to validate our findings.

The prognostic relationship between donor age and infectious risk in liver transplant patients with nonalcoholic steatohepatitis: Analysis of UNOS database.

BACKGROUND & AIMS: We investigate the effects of advancing donor age on the prognostic outcomes of patients with NASH who undergo liver transplant (LT), with a specialized attention toward infectious outcomes post-LT. METHODS: The UNOS-STAR registry was used to select 2005 to 2019 LT recipients with NASH, who were stratified by donor age into the following categories: recipients with younger donors (less than 50 years of age-reference), quinquagenarian donors, sexagenarian donors, septuagenarian donors, and octogenarian donors. Cox regression analyses were conducted for all-cause mortality, graft failure, infectious causes of death. RESULTS: From a total of 8888 recipients, the quinquagenarian, septuagenarian, and octogenarian donor cohorts showed greater risk of all-cause mortality (quinquagenarian: aHR 1.16 95%CI 1.03-1.30; septuagenarian: aHR 1.20 95%CI 1.00-1.44; octogenarian: aHR 2.01 95%CI 1.40-2.88). With advancing donor age, there was an increased risk of death from sepsis (quinquagenarian: aHR 1.71 95% CI 1.24-2.36; sexagenarian: aHR 1.73 95% CI 1.21-2.48; septuagenarian: aHR 1.76 95% CI 1.07-2.90; octogenarian: aHR 3.58 95% CI 1.42-9.06) and infectious causes (quinquagenarian: aHR 1.46 95% CI 1.12-1.90; sexagenarian: aHR 1.58 95% CI 1.18-2.11; septuagenarian: aHR 1.73 95% CI 1.15-2.61; octogenarian: aHR 3.70 95% CI 1.78-7.69). CONCLUSION: NASH patients who receive grafts from elderly donors exhibit higher risk of post-LT mortality, especially due to infection.

The nationwide trends in hospital admissions, deaths, and costs related to hepatitis C stratified by psychiatric disorders and substance use: an analysis of US hospitals between 2016 and 2019.

BACKGROUND AND AIMS: Hepatitis C virus (HCV) is a prominent liver disease that often presents with mental illness. We stratify the HCV population and review its healthcare burden on the US hospital system. METHODS: The US National Inpatient Sample was used to select admissions related to HCV between 2016 and 2019. Weights were assigned to discharges, and trend analyses were performed. Strata were formed across demographics, comorbidities, psychiatric and substance use conditions, and other variables. Outcomes of interest included hospitalization incidences, mortality rates, total costs, and mean per-hospitalization costs. RESULTS: From 2016 to 2019, there were improvements in mortality and hospitalization incidence for HCV, as well as a decline in aggregate costs across the majority of strata. Exceptions that showed cost growth included admissions with multiple psychiatric, stimulant use, or poly-substance use disorders, and a history of homelessness. Admissions with no psychiatric comorbidities, admissions with no substance use comorbidities, and admissions with housing and without HIV comorbidity showed decreasing total costs. Along with per-capita mean costs, admissions with comorbid opioid use, bipolar, or anxiety disorder showed significant increases. No significant trends in per-capita costs were found in admissions without mental illness diagnoses. CONCLUSIONS: Most strata demonstrated decreases in hospitalization incidences and total costs surrounding HCV; however, HCV cases with mental illness diagnoses saw expenditure growth. Cost-saving mechanisms for these subgroups are warranted.
