RESUMEN
BACKGROUND AND AIMS: Pre-liver transplant (LT) functional status is an important determinant of prognosis post LT. There is insufficient data on how functional status affects outcomes of transplant recipients based on the specific etiology of liver disease. We stratified LT recipients by etiology of liver disease to evaluate the effects of functional status on post-LT prognosis in each subgroup. METHODS: 2005-2019 United Network for Organ Sharing (UNOS) Standard Transplant Analysis and Research (STAR) was used to select patients with liver transplant. A total of 14,290 patients were included in the analysis. These patients were stratified by functional status according to Karnofsky Performance Scale (KPS) score: no assistance, some assistance, or total assistance. They were then further divided into six diagnosis categories: metabolic dysfunction-associated steatotic liver disease (MASLD), hereditary disorders, hepatitis C, hepatitis B, autoimmune disease (AID), and alcoholic liver disease (ALD). Primary endpoints included all-cause mortality and graft failure, while secondary endpoints included organ-specific causes of death. Those under the age of 18 and those with non-whole liver or prior liver transplantation were excluded. RESULTS: Patients with MASLD requiring some assistance (aHR: 1.57, 95% CI 1.03-2.39, p = 0.04) and those requiring total assistance (aHR: 2.32, 95% CI 1.48-3.64, p < 0.001) had higher incidences of graft failure compared to those requiring no assistance. Those with MASLD requiring total assistance had a higher all-cause mortality rate than those needing no assistance (aHR: 1.62, 95% CI 1.38-1.89, p < 0.001). Patients with hereditary causes of liver disease showed a lower incidence of all-cause mortality in recipients needing some assistance compared with those needing no assistance (aHR: 0.52, 95% CI 0.34-0.80, p = 0.003). LT recipients with hepatitis C, AID, and ALD all showed higher incidences of all-cause mortality in the total assistance cohort when compared to the no assistance cohort. For the secondary endpoints of specific cause of death, transplant recipients with MASLD needing total assistance had higher rates of death due to general cardiac causes, graft rejection, general infectious causes, sepsis, general renal causes, and general respiratory causes. CONCLUSION: Patients with MASLD cirrhosis demonstrated the worst overall outcomes, suggesting that this population may be particularly vulnerable. Poor functional status in patients with end-stage liver disease from hepatitis B or hereditary disease was not associated with a significantly increased rate of adverse outcomes, suggesting that the KPS score may not be broadly applicable to all patients awaiting LT.
RESUMEN
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 100â 000 hospitalizations due to WD were 1075, 1180, 1140, and 1330 ( R2 â =â 0.75; P â =â 0.13) from 2016 to 2019. Within the demographics, there was an increase in admissions among patients greater than 65 years of age ( R2 â =â 0.90; P â =â 0.05) and White patients ( R2 â =â 0.97; P â =â 0.02). Assessing WD-related mortality rates, there was an increase in the mortality rate among those in the first quartile of income ( R2 â =â 1.00; P â <â 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 â =â 0.47; P â =â 0.32). There was an increasing total cost trend for Asian or Pacific Islander patients ( R2 â =â 0.90; P â =â 0.05). Interestingly, patients with cirrhosis demonstrated a decreased trend in the total costs ( R2 â =â 0.97; P â =â 0.02). CONCLUSION: Our study demonstrated that certain ethnicity groups, income classes and comorbidities had increased admissions or costs among patients admitted with WD.

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.

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.

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 â =â 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.

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.

Diaphragm plication is a surgical treatment of unilateral diaphragm paralysis, in which the affected diaphragm is sutured in place. Because the right diaphragm sits on top of the liver, right-sided diaphragm plication can injure the liver and lead to hepatic compartment syndrome resulting in acute liver injury. We report a case of a 59-year-old woman with a history of multilevel disk degeneration and alcohol use disorder who underwent right-sided diaphragm plication. After surgery, she complained of abdominal pain and was found to have severely elevated liver-associated enzymes and evidence of acute liver injury, which resolved with supportive care.
RESUMEN
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.

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%, Pâ =â 0.004) and clinical illness, including hypotension (11.80% vs. 7.15%, Pâ =â 0.002) and ventilator use (40.80% vs. 30.00%, Pâ <â 0.001). When stratified by race, Black patients had longer hospital stays (Black vs. White, 8.76 days vs. 7.46 days, Pâ =â 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.

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.

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.

Background: Autoimmune hepatitis (AIH) can result in end-stage liver disease that requires inpatient treatment of the hepatic complications. Given this phenomenon, it is important to analyse the impact of gender and race on the outcomes of patients who are admitted with AIH using a national hospital registry. Methods: The 2012-2017 National Inpatient Sample database was used to select patients with AIH, who were stratified using gender and race (Hispanics and blacks as cases and whites as reference). Propensity score matching was employed to match the controls with cases and compare mortality, length of stay and hepatic complications. Results: After matching, there were 4609 females and 4609 males, as well as 3688 blacks and 3173 Hispanics with equal numbers of whites, respectively. In multivariate analysis, females were less likely to develop complications, with lower rates of cirrhosis, ascites, variceal bleeding, hepatorenal syndrome, encephalopathy and acute liver failure (ALF); they also exhibited lower length of stay (adjusted OR, aOR 0.96 95% CI 0.94 to 0.97). When comparing races, blacks (compared with whites) had higher rates of ALF and hepatorenal syndrome related to ALF, but had lower rates of cirrhosis-related encephalopathy; in multivariate analysis, blacks had longer length of stay (aOR 1.071, 95% CI 1.050 to 1.092). Hispanics also exhibited higher rates of hepatic complications, including ascites, varices, variceal bleeding, spontaneous bacterial peritonitis and encephalopathy. Conclusion: Males and minorities are at a greater risk of developing hepatic complications and having increased hospital costs when admitted with AIH.
RESUMEN
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.

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.

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.

BACKGROUND: Patients with autoimmune hepatitis (AIH) may co-present with features of primary biliary cholangitis (PBC) or primary sclerosing cholangitis (PSC). Using a national transplant registry, the outcomes of patients with these autoimmune liver conditions were compared. METHODS: The UNOS-STAR registry was used to select a study population of AIH, PSC, and PBC liver transplant (LT) patients. Living and multi-organ transplant cases were excluded. Using the UNOS-registered diagnoses, the study population was subdivided into those with nonoverlapping autoimmune liver diseases and those with overlapping forms (e.g., AIH-PBC). Outcomes were compared, using endpoints such as all-cause mortality, graft failure, and organ-system specific causes of death. RESULTS: The main analysis featured 2048 entries, with 1927 entries having nonoverlapping AIH, 52 entries having PSC overlap, and 69 entries having PBC overlap. Patients with PBC overlap were more likely to have graft failure (adjusted hazard ratio [aHR] 3.46 95% CI 1.70-7.05), mortality secondary to respiratory causes (aHR 3.57 95% CI 1.23-10.43), and mortality secondary to recurrent disease (aHR 9.53 95% CI 1.85-49.09). Case incidence rates reflected these findings, expressed in events per 1000 person-years. For patients with PBC overlap and nonoverlapping AIH cases, respectively. Graft failure: 28.87 events vs. 9.42 events, mortality secondary to respiratory causes: 12.83 deaths vs. 3.77 deaths, mortality secondary to recurrent disease: 6.42 deaths vs. 1.26 deaths. Those with AIH-PSC overlap experienced a higher risk of death from graft infection (aHR 10.43 95% CI 1.08-100.37; case-incidence rate: 3.89 vs. 0.31 mortalities per 1000 person-years). Supplementary analysis showed similar findings, in which overlapping autoimmune conditions were associated with higher adverse outcome rates. CONCLUSION: Patients with AIH-PBC overlap have higher risk of mortality due to recurrent liver disease and respiratory causes, and patients with AIH-PSC overlap have higher risk of mortality due to graft infection. While further prospective studies are needed to clarify the underlying mechanisms related to these findings, our study characterizes the prognostic implications of AIH overlap on post-LT mortality and graft failure risks.

BACKGROUND AND AIMS: The presence of perioperative diabetes may lead to increased mortality risks following liver transplant (LT) in patients with non-alcoholic steatohepatitis (NASH). This risk factor was evaluated using a UNOS-STAR national database. METHODS: The UNOS-STAR liver transplant registry 2005-2019 was used to select patients with NASH (including cryptogenic liver disease). The following populations were excluded: those younger than 18 years old and those with living donors/dual transplants. Selected patients were stratified into those with and without pre-LT diabetes and compared to the individual mortality endpoints using iterative Cox analyses. RESULTS: 6324 recipients with and 8251 without diabetes were selected. The median follow-up time was 3.07 years. Those with diabetes were older (58.50 vs. 54.50 years, p < 0.001), were more likely to be Hispanic or Asian, and had higher BMI than the non-diabetics (31.10 vs. 29.70 kg/m2 p < 0.001); however, there was no difference in gender (female 41.9 vs. 43.1% p = 0.170). Compared to non-diabetics, recipients with diabetes had a higher rate of all-cause mortality (61.68 vs. 47.80 per 1000 person-years). In multivariate iterations, pre-LT diabetes was associated with all-cause mortality (aHR 1.19 95% CI 1.11-1.27) as well as deaths due to cardiac (p = 0.014 aHR 1.24 95% CI 1.04-1.46) and renal causes (p = 0.039 aHR 1.38 95% CI 1.02-1.87). CONCLUSION: The presence of pre-LT diabetes is associated with all-cause mortality and deaths due to cardiac and renal causes following LT. The findings warrant an early preoperative screening procedure to ensure that patients with diabetes have their metabolic risk factors optimized prior to LT.

PURPOSE: This study systematically evaluated the implications of advanced age on post-surgical outcomes following gastrectomy for gastric cancer using a national database. MATERIALS AND METHODS: The 2011-2017 National Inpatient Sample was used to isolate patients who underwent gastrectomy for gastric cancer. From this, the population was stratified into those belonging to the younger age cohort (18-59 years), sexagenarians, septuagenarians, and octogenarians. The younger cohort and each advanced age category were compared in terms of the following endpoints: mortality following surgery, length of hospital stay, charges, and surgical complications. RESULTS: This study included a total of 5,213 patients: 1,366 sexagenarians, 1,490 septuagenarians, 743 octogenarians, and 1,614 under 60 years of age. Between the younger cohort and sexagenarians, there was no difference in mortality (2.27 vs. 1.67%; P=0.30; odds ratio [OR], 1.36; 95% confidence interval [CI], 0.81-2.30), length of stay (11.0 vs. 11.1 days; P=0.86), or charges ($123,557 vs. $124,425; P=0.79). Compared to the younger cohort, septuagenarians had higher rates of in-hospital mortality (4.30% vs. 1.67%; P<0.01; OR, 2.64; 95% CI, 1.67-4.16), length of stay (12.1 vs. 11.1 days; P<0.01), and charges ($139,200 vs. $124,425; P<0.01). In the multivariate analysis, septuagenarians had higher mortality (P=0.01; adjusted odds ratio [aOR], 2.01; 95% CI, 1.18-3.43). Similarly, compared to the younger cohort, octogenarians had a higher rate of mortality (7.67% vs. 1.67%; P<0.001; OR, 4.88; 95% CI, 3.06-7.79), length of stay (12.3 vs. 11.1 days; P<0.01), and charges ($131,330 vs. $124,425; P<0.01). In the multivariate analysis, octogenarians had higher mortality (P<0.001; aOR, 4.03; 95% CI, 2.28-7.11). CONCLUSIONS: Advanced age (>70 years) is an independent risk factor for postoperative death in patients with gastric cancer undergoing gastrectomy.
RESUMEN
BACKGROUND: The presence of clinical frailty can pose an escalated risk toward surgical outcomes including in cases that involve minimally invasive procedures. Given this premise, we evaluate the effects of frailty on post-appendectomy outcomes using a national in-hospital registry. METHODS: 2011-2017 National Inpatient Sample was used to isolate inpatient appendectomy cases; the population as stratified using Johns Hopkins ACG clinical frailty, expressed as either binary or ternary (prefrailty, frailty, and without frailty) indicators. The controls were matched to frailty-present groups using propensity score matching and compared to various endpoints, including mortality, length of stay (LOS), hospitalization costs, and postoperative complications. RESULTS: Post-match, there were 11,758 with and without frailty per binary; and 1236 frail, 10,522 pre-frail with respective equal number controls per ternary indicator. Using binary term, frail patients had higher mortality (4.22 vs 1.49% OR 2.92 95%CI 2.45-3.47), LOS (14.3 vs 5.35d p < 0.001), and costs ($160,700 vs $64,141 p < 0.001). In multivariate, frail patients had higher mortality (aOR 2.77 95%CI 2.32-3.31), as well as higher rates of postoperative complications. Using ternary term, frail patients had higher mortality (5.02 vs 2.27% OR 2.28 95%CI 1.45-3.59), LOS (18.9 vs 5.66 day p < 0.001) and costs ($200,517 vs $66,193 p < 0.001). In multivariate, frail patients had higher mortality (aOR 2.16 95%CI 1.35-3.43) and complications. Those with pre-frailty had higher mortality (4.12 vs 1.47% OR 2.88 95%CI 2.39-3.46), LOS (13.8 vs 5.34 day p < 0.001) and costs ($156,022 vs $63,772 p < 0.001). In multivariate, pre-frailty patients had higher mortality (aOR 2.79 95%CI 2.31-3.37) and complications. CONCLUSIONS: Frailty and prefrailty (using the ternary indicator) are associated with increased postoperative mortality and complication in patients who undergo appendectomy; given this finding, it is imperative that these vulnerable patients are identified early in the preoperative phase and are provided risk-modifying measures to ameliorate risks and optimize outcomes.
