Predictors for Lymph Node Metastasis and Survival of Patients with T1b Esophageal Adenocarcinoma Treated with Surgery and Endoscopic Therapy: An Analysis of Surveillance, Epidemiology, and End Results Database. Gastrointest Endosc 2024:S0016-5107(24)03190-0. [PMID: 38734257 DOI: 10.1016/j.gie.2024.05.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 04/22/2024] [Accepted: 05/06/2024] [Indexed: 05/13/2024]
Abstract
BACKGROUND AND AIMS Limited data exists regarding the long-term outcomes of endoscopic therapy (ET) with or without chemoradiation therapy (CRT) for T1b esophageal adenocarcinoma (EAC). Our aim was to identify the risk factors for lymph node metastasis (LNM) in T1b EAC and assess how the chosen treatment modality affects overall survival (OS) and cancer-specific survival (CSS). METHODS We analyzed histologically confirmed T1b EAC patients diagnosed between 2004 and 2018 using Surveillance Epidemiology and End Results database. Focusing on T1bN0M0 staging, we divided the patients into two groups: ET (n=174) and surgery (n=769), and calculated OS and CSS rates. RESULTS Out of 1418 patients with T1b EAC, 228 cases (16.1%) exhibited LNM at diagnosis. Notable risk factors for LNM included poorly differentiated tumor and lesion size ≥20 mm. For T1bN0M0 cases, ET was commonly performed from 2009 to 2018 (OR 4.3), especially for patients aged ≥ 65 years (OR 3.1) with tumor size <20mm (OR 2.3). During 50 months median follow-up, age ≥ 65 years (HR 1.9), ET (HR 1.5), and CRT (HR 1.4) were associated with poorer OS. Factors linked to decreased CSS were age ≥ 65 years (sub hazard ratio (SHR) 1.6), poorly differentiated tumors (SHR 1.5), and CRT (SHR 1.5). CONCLUSION In T1b EAC, tumor size ≥20mm and poor differentiation are notable risk factors for LNM. ET showed comparable CSS outcomes to surgery for carefully selected T1bN0M0 lesions. CRT did not provide additional survival benefit for these lesions; however, large scale studies are required to validate this finding.

Abstract
BACKGROUND Most Crohn's disease [CD] patients require surgery. Ileitis recurs after most ileocolectomies and is a critical determinant for outcomes. The impacts of ileocolectomy-induced bile acid [BA] perturbations on intestinal microbiota and inflammation are unknown. We characterized the relationships between ileocolectomy, stool BAs, microbiota and intestinal inflammation in inflammatory bowel disease [IBD]. METHODS Validated IBD clinical and endoscopic assessments were prospectively collected. Stool primary and secondary BA concentrations were compared based on ileocolectomy and ileitis status. Primary BA thresholds for ileitis were evaluated. Metagenomic sequencing was use to profile microbial composition and function. Relationships between ileocolectomy, BAs and microbiota were assessed. RESULTS In 166 patients, elevated primary and secondary BAs existed with ileocolectomy. With ileitis, only primary BAs [795 vs 398 nmol/g, p = 0.009] were higher compared to without ileitis. The optimal primary BA threshold [≥228 nmol/g] identified ileitis on multivariable analysis [odds ratio = 2.3, p = 0.04]. Microbial diversity, Faecalibacterium prausnitzii and O-acetylhomoserine aminocarboxypropyltransferase [MetY] were decreased with elevated primary BAs. Amongst ileocolectomy patients, only those with elevated primary BAs had diversity, F. prausnitzii and MetY reductions. Those with both ileocolectomy and intermediate [p = 0.002] or high [≥228 nmol/g, p = 9.1e-11]] primary BA concentrations had reduced F. prausnitzii compared to without ileocolectomy. Those with ileocolectomy and low [<29.2 nmol/g] primary BA concentrations had similar F. prausnitzii to those without ileocolectomy [p = 0.13]. MetY was reduced with ileitis [p = 0.02]. CONCLUSIONS Elevated primary BAs were associated with ileitis, and reduced microbial diversity, F. prausnitzii abundance and enzymatic abundance of MetY [acetate and l-methionine-producing enzyme expressed by F. prausnitzii], and were the only factors associated with these findings after ileocolectomy.

Predicting inpatient mortality in patients with inflammatory bowel disease: A machine learning approach. J Gastroenterol Hepatol 2023; 38:241-250. [PMID: 36258306 PMCID: PMC10099396 DOI: 10.1111/jgh.16029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Revised: 07/25/2022] [Accepted: 10/13/2022] [Indexed: 12/09/2022]
Abstract
BACKGROUND AND AIM Data are lacking on predicting inpatient mortality (IM) in patients admitted for inflammatory bowel disease (IBD). IM is a critical outcome; however, difficulty in its prediction exists due to infrequent occurrence. We assessed IM predictors and developed a predictive model for IM using machine-learning (ML). METHODS Using the National Inpatient Sample (NIS) database (2005-2017), we extracted adults admitted for IBD. After ML-guided predictor selection, we trained and internally validated multiple algorithms, targeting minimum sensitivity and positive likelihood ratio (+LR) ≥ 80% and ≥ 3, respectively. Diagnostic odds ratio (DOR) compared algorithm performance. The best performing algorithm was additionally trained and validated for an IBD-related surgery sub-cohort. External validation was done using NIS 2018. RESULTS In 398 426 adult IBD admissions, IM was 0.32% overall, and 0.87% among the surgical cohort (n = 40 784). Increasing age, ulcerative colitis, IBD-related surgery, pneumonia, chronic lung disease, acute kidney injury, malnutrition, frailty, heart failure, blood transfusion, sepsis/septic shock and thromboembolism were associated with increased IM. The QLattice algorithm, provided the highest performance model (+LR: 3.2, 95% CI 3.0-3.3; area-under-curve [AUC]:0.87, 85% sensitivity, 73% specificity), distinguishing IM patients by 15.6-fold when comparing high to low-risk patients. The surgical cohort model (+LR: 8.5, AUC: 0.94, 85% sensitivity, 90% specificity), distinguished IM patients by 49-fold. Both models performed excellently in external validation. An online calculator (https://clinicalc.ai/im-ibd/) was developed allowing bedside model predictions. CONCLUSIONS An online prediction-model calculator captured > 80% IM cases during IBD-related admissions, with high discriminatory effectiveness. This allows for risk stratification and provides a basis for assessing interventions to reduce mortality in high-risk patients.

Impact of Inflammatory Bowel Disease Therapies on Durability of Humoral Response to SARS-CoV-2 Vaccination. Clin Gastroenterol Hepatol 2022; 20:e1493-e1499. [PMID: 34896283 PMCID: PMC8654702 DOI: 10.1016/j.cgh.2021.12.007] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 11/22/2021] [Accepted: 12/04/2021] [Indexed: 02/07/2023]
Abstract
Immunization against the spike protein of SARS-CoV-2 reduces transmission1,2 and severe outcomes. However, little is known regarding the impact of immune-mediated diseases and immunosuppressive medications on the efficacy of vaccination. Vaccination immunity is transient, with breakthrough cases increasing at longer time intervals since the last dose.3,4 Although there are data on SARS-CoV-2 vaccine on early seroconversion in patients with inflammatory bowel disease (IBD),5 no data in the same cohort exist describing the durability of these antibodies over time. We sought to investigate the impact of IBD and its therapies on postvaccination antibody response and kinetics of immunogenicity decline, because these findings may better inform clinical guidelines and recommendations on precautions and booster vaccination.

Abstract
Machine learning models may outperform traditional statistical regression algorithms for predicting clinical outcomes. Proper validation of building such models and tuning their underlying algorithms is necessary to avoid over-fitting and poor generalizability, which smaller datasets can be more prone to. In an effort to educate readers interested in artificial intelligence and model-building based on machine-learning algorithms, we outline important details on cross-validation techniques that can enhance the performance and generalizability of such models.

Impact of atrial fibrillation on in-hospital outcomes among hospitalizations for cardiac surgery: an analysis of the National Inpatient Sample. J Investig Med 2022; 70:899-906. [PMID: 34987105 DOI: 10.1136/jim-2021-001864] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/07/2021] [Indexed: 11/03/2022]
Abstract
The short-term impact of atrial fibrillation (AF) on cardiac surgery hospitalizations has been previously reported in cohorts of various sizes, but results have been variable. Using the 2005-2014 National Inpatient Sample, we identified all adult hospitalizations for cardiac surgery using the International Classification of Diseases, Ninth Revision, Clinical Modification as any procedure code and AF as any diagnosis code. We estimated the impact of AF on inpatient mortality, length of stay (LOS), and cost of hospitalization using survey-weighted, multivariable logistic, accelerated failure-time log-normal, and log-transformed linear regressions, respectively. Additionally, we exact-matched AF to non-AF hospitalizations on various confounders for the same outcomes. A total of 1,269,414 hospitalizations were noted for cardiac surgery during the study period. Coexistent AF was found in 44.9% of these hospitalizations. Overall mean age was 65.6 years, 40.9% were female, mean LOS was 11.6 days, and inpatient mortality was 4.5%. Stroke rate was lower in AF hospitalizations (1.8% vs 2.1%, p<0.001). Mortality was lower in the AF (3.9%) versus the non-AF (5%) group (exact-matched OR or emOR=0.48, 95% CI 0.29 to 0.80, p<0.001; 987 matched pairs, n=2423), with similar results after procedural stratification: isolated valve replacement/repair (emOR=0.38, p<0.001), isolated coronary artery bypass graft (CABG) (emOR=0.33, p<0.001), and CABG with valve replacement/repair (emOR=0.55, p<0.001). A 12% increase was seen in LOS in the AF subgroup (exact-matched time ratio=1.12, 95% CI 1.10 to 1.14, p<0.001) among hospitalizations which underwent valve replacement/repair with or without CABG. Hospitalizations for cardiac surgery which had coexistent AF were found to have lower inpatient mortality risk and stroke prevalence but higher LOS and hospitalization costs compared with hospitalizations without AF.

Trends in hospitalization, mortality, and timing of colonoscopy in patients with acute lower gastrointestinal bleeding. Endosc Int Open 2021; 9:E777-E789. [PMID: 34079858 PMCID: PMC8159619 DOI: 10.1055/a-1352-3204] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Accepted: 12/09/2020] [Indexed: 02/07/2023] Open
Abstract
Abstract
Background and study aims Current guidelines conditionally recommend performing early colonoscopy (EC) (< 24 hours) in patients admitted with acute lower gastrointestinal bleeding (LGIB). It remains unclear whether this practice is implemented widely. Therefore, we used the Nationwide Inpatient Sample to investigate trends for timing of colonoscopy in patients admitted with acute LGIB. We also assessed trend of hospitalization and mortality in patients with LGIB.
Patients and methods Adult patients with LGIB admitted from 2005 to 2014 were examined. ICD-9-CM codes were used to extract LGIB discharges. Trends were assessed using Cochrane-Armitage test. Factors associated with mortality, cost of hospitalization, and length of stay (LOS) were assessed by multivariable mixed-effects and exact-matched logistic, linear regression, and accelerated-failure time models, respectively.
Results A total of 814,647 patients with LGIB were included. The most common etiology of LGIB was diverticular bleeding (49 %) and 45 % of patients underwent EC. Over the study period, there was no change in the trend of colonoscopy timing. Although admission with LGIB increased over the study period, the mortality rate decreased for patients undergoing colonoscopy. Independent predictors of mortality were age, surgery (colostomy/colectomy) during admission, intensive care unit admission, acute kidney injury, and blood transfusion requirement. Timing of colonoscopy was not associated with mortality benefit. However, cost of hospitalization was $ 1,946 lower and LOS was 1.6 days shorter with EC.
Conclusion Trends in colonoscopy timing in management of LGIB have not changed over the years. EC is associated with lower LOS and cost of hospitalization but it does not appear to improve inpatient mortality.

Inpatient Mortality Benefit with Transjugular Intrahepatic Portosystemic Shunt for Hospitalized Hepatorenal Syndrome Patients. Dig Dis Sci 2020; 65:3378-3388. [PMID: 32062714 DOI: 10.1007/s10620-020-06136-2] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2019] [Accepted: 02/04/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND It has been reported that transjugular intrahepatic portosystemic shunting (TIPS) might be utilized as a salvage option for hepatorenal syndrome (HRS), while randomized controlled trials are pending and real-world contemporary data on inpatient mortality is lacking. METHODS We conducted an observational retrospective cohort study from the National Inpatient Sample from 2005 to 2014. We included all adult patients admitted with HRS and cirrhosis, using ICD 9-CM codes. We excluded cases with variceal bleeding, Budd-Chiari, end-stage renal disease, liver transplant and transfers to acute-care facilities. TIPS' association with inpatient mortality was assessed using multivariable mixed-effects logistic regression, as well as exact-matching, thus mitigating for TIPS selection bias. The exact-matched analysis was repeated among TIPS-only versus dialysis-only patients. RESULTS A total of 79,354 patients were included. Nine hundred eighteen (1.2%) underwent TIPS. Between TIPS and non-TIPS groups, mean age (58 years) and gender (65% males) were similar. Overall mortality was 18% in TIPS and 48% in dialysis-only cases (n = 10,379; 13.1%). Ninety six (10.5%) TIPS patients underwent dialysis. In-hospital mortality in TIPS patients was twice less likely than in non-TIPS patients (adjusted odds ratio [aOR] = 0.43, 95% CI 0.30-0.62; p < 0.001), with similar results in matched analysis [exact-matched (em) OR = 0.39, 95% CI 0.17-0.89; p < 0.024; groups = 96; unweighted n = 463]. Head-to-head comparison showed that TIPS-only patients were 3.3 times less likely to succumb inpatient versus dialysis-only patients (contrast aOR = 0.31, 95% CI 0.20-0.46; p < 0.001), with similar findings post-matching (emOR = 0.22, 95% CI 0.15-0.33; p < 0.001; groups = 54, unweighted n = 1457). CONCLUSIONS Contemporary, real-world data reveal that TIPS on its own, and when compared to dialysis, is associated with decreased inpatient mortality when utilized in non-bleeders-HRS patients. Further randomized studies are needed to establish the long-term benefit of TIPS in these patients.

Abstract
BACKGROUND This study evaluates sex differences in the natural history of descending thoracic and thoracoabdominal aortic aneurysms (DTTAAs). METHODS In all, 907 patients with descending thoracic and thoracoabdominal aortic sizes greater than 3 cm were retrospectively reviewed. Growth rate estimates were performed utilizing an instrumental variables approach. Yearly complication rates as a function of aortic size were computed. RESULTS There were 615 men (67.8%) and 292 women (32.2%) treated between 1990 and 2018, with mean aortic diameters of 4.1 ± 1.4 cm and 4.8 ± 1.6 cm, respectively (P < .001). The mean growth rate of DTTAAs was 0.17 cm per year in men and 0.25 cm per year in women (P < .001), increasing with increasing aneurysm size. Dissection, rupture, or aortic death or the combination of the three occurred at double the rate for women compared with men (5.8% vs 2.3% per year for the combined endpoint). Diameter of DTTAA greater than 5 cm was associated with 26.3% (male) and 33.1% (female) average yearly rates of the composite endpoint of rupture, dissection, and death (P < .05). The probability of fatal complications (rupture and death) increased sharply at 5.75 cm in both sexes. Between 4.5 and 5.75 cm, there was another hinge-point of higher probability of fatal complications among women. CONCLUSIONS Women diagnosed with DTTAA fare worse. Faster aneurysm growth and higher rates of dissection, rupture, and aortic death are apparent among women. Current guidelines recommend surgical intervention at 5.5 to 6 cm for DTTAAs without sex considerations. Our findings suggest that increased virulence of DTTAA in women may indicate surgery at a somewhat smaller diameter.

Abstract
BACKGROUND Alcohol-related and alcohol withdrawal (AW) hospitalizations are routinely underestimated in the geriatric population and can have a significant impact on healthcare resource utilization. OBJECTIVES To examine various patient-characteristics, hospitalization-outcomes, and prevalence of AW related-hospitalizations. METHODS In this retrospective study, we examined the objectives mentioned above over a 10-year period (2005 to 2014) using the Nationwide Inpatient Sample (NIS) in adults aged 65 years or older. National estimates of trends for AW prevalence and matched-regression analyses were conducted. RESULTS Increased prevalence of hospitalizations for AW was observed (148-cases-per-100,000-discharges in 2005 to 283-cases-per-100,000-discharges in 2014). Of the overall nationwide hospital admissions in patients aged 65 and older (128,111,787), 0.21% (264,786) with documented AW were identified. Of these, those of age 65-74 years accounted for 72.7% of admissions with the highest prevalence amongst males (males accounted for 74%, women 26%) and individuals of Caucasian ethnicity (79.9%).On comparing AW to Non-AW related-hospitalizations, patients admitted with AW had a higher median length of stay (five vs. four days), more significant functional decline with only 44.2% discharges being discharged home (vs. 47.2%) and 34.4% AW related discharges requiring discharge to skilled nursing facilities (vs. 28.5%). Higher hospitalization costs totaling $4,000 more on bivariate analysis were observed for the AW group. CONCLUSIONS The prevalence of admissions with AW has increased in the inpatient geriatric population, contributing to increased length of stay, higher hospitalization costs, and greater functional decline. Recognition of these findings and the development of programs supporting older adults with alcohol use disorder may improve patient outcomes.

Abstract
BACKGROUND AND AIMS The opioid epidemic has become increasingly concerning, with the ever-increasing prescribing of opioid medications in recent years, especially in inflammatory bowel disease [IBD] patients with chronic pain. We aimed to isolate the effect of opioid use disorder [OUD] on 30-day readmission risk after an IBD-related hospitalization. METHODS We retrospectively extracted IBD-related adult hospitalizations and 30-day, any-cause, readmissions from the National Readmissions Database [period 2010-2014]. OUD and 30-day readmission trends were calculated. Conventional and exact-matched [EM] logistic regression and time-to-event analyses were conducted among patients who did not undergo surgery during the index hospitalization, to estimate the effect of OUD on 30-day readmission risk. RESULTS In total, 487 728 cases were identified: 6633 [1.4%] had documented OUD And 308 845 patients [63.3%] had Crohn's disease. Mean age was 44.8 ± 0.1 years, and 54.3% were women. Overall, 30-day readmission rate was 19.4% [n = 94,546], being higher in OUD patients [32.6% vs 19.2%; p < 0.001]. OUD cases have been increasing [1.1% to 1.7%; p-trend < 0.001], while 30-day readmission rates were stable [p-trend = 0.191]. In time-to-event EM analysis, OUD patients were 47% more likely (hazard ratio 1.47; 95% confidence interval [CI]:1.28-1.69; p < 0.001) to be readmitted, on average being readmitted 32% earlier [time ratio 0.68; 95% CI: 0.59-0.78; p < 0.001]. CONCLUSION OUD prevalence has been increasing in hospitalized IBD patients from 2010 to 2014. On average, one in five patients will be readmitted within 30 days, with up to one in three among the OUD subgroup. OUD is significantly associated with increased 30-day readmission risk in IBD patients and further measures relating to closer post-discharge outpatient follow-up and pain management should be considered to minimize 30-day readmission risk.

Significance of peripheral eosinophilia for diagnosis of IgG4-related disease in subjects with elevated serum IgG4 levels. Pancreatology 2020; 20:74-78. [PMID: 31791884 DOI: 10.1016/j.pan.2019.11.016] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2019] [Revised: 11/24/2019] [Accepted: 11/26/2019] [Indexed: 12/11/2022]
Abstract
OBJECTIVES In this study, we aim to assess the diagnostic utility of elevated serum IgG4 (sIgG4) concentration alone and in combination with peripheral eosinophilia (PE) for IgG4-related disease (IgG4-RD). METHODS From the Mayo Clinic, Rochester electronic medical record database we identified 409 patients with above normal levels of sIgG4 (reference range 121-140 mg/dL) who had sIgG4 measured to differentiate IgG4-RD from another disease. RESULTS Among 409 patients with any elevation in sIgG4 levels, 129 (31.5%) had a definite diagnosis of IgG4-RD. The prevalence of PE increased with increasing sIgG4 levels and was more likely to be seen in subjects with IgG4-RD vs. non-IgG4-RD at ≥1X (n = 35/120, 29.2% vs. n = 23/258, 8.9%; p < 0.001), ≥2X (n = 23/64, 35.9% vs. n = 5/54,9.3%; p = 0.001) and ≥3X (n = 18/42, 42.9% vs. n = 0/9, 0%; p = 0.015) of sIgG4 upper limit of normal (ULN), respectively. After adjusting for gender and age, sIgG4 levels ≥ 2X ULN with PE as a predictor, had a higher positive predictive value in predicting IgG4-RD (72.2% vs. 65.9%) with an Area Under the Receiver Operatic Characteristic Curve (AUC) of 0.776, compared to sIgG4 ≥ 2X ULN without PE predictor (AUC = 0.74), p = 0.016. PE, sIgG4≥2X ULN, male gender, and age independently predicted the disease with odds ratio of 4.89 (95% CI:2.51-9.54), 3.78 (95% CI:2.27-6.28), 2.78 (95% CI:1.55-4.97), and 1.03 (95% CI:1.02-1.05), respectively. CONCLUSION Even in subjects in whom IgG4-RD is suspected, only a minority (∼30%) with elevated sIgG4 levels have IgG4-RD. sIgG4 by itself is more specific at higher levels, though never diagnostic. PE increases with increasing sIgG4 and adds diagnostic value at higher sIgG4 levels.

[PMID: 31759905 DOI: 10.1016/j.pan.2019.11.004] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Revised: 10/24/2019] [Accepted: 11/12/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND The opioid epidemic in the United States has been on the rise. Acute exacerbations of chronic pancreatitis (AECP) patients are at higher risk for Opioid Use Disorder (OUD). Evidence on OUD's impact on healthcare utilization, especially hospital re-admissions is scarce. We measured the impact of OUD on 30-day readmissions, in patients admitted with AECP from 2010 to 2014. METHODS This is a retrospective cohort study which included patients with concurrently documented CP and acute pancreatitis as first two diagnoses, from the National Readmissions Database (NRD). Pancreatic cancer patients and those who left against medical advice were excluded. We compared the 30-day readmission risk between OUD-vs.-non-OUD, while adjusting for other confounders, using multivariable exact-matched [(EM); 18 confounders; n = 28,389] and non-EM regression/time-to-event analyses. RESULTS 189,585 patients were identified. 6589 (3.5%) had OUD. Mean age was 48.7 years and 57.5% were men. Length-of-stay (4.4 vs 3.9 days) and mean index hospitalization costs ($10,251 vs. $9174) were significantly higher in OUD-compared to non-OUD-patients (p < 0.001). The overall mean 30-day readmission rate was 27.3% (n = 51,806; 35.3% in OUD vs. 27.0% in non-OUD; p < 0.001). OUD patients were 25% more likely to be re-admitted during a 30-day period (EM-HR: 1.25; 95%CI: 1.16-1.36; p < 0.001), Majority of readmissions were pancreas-related (60%), especially AP. OUD cases' aggregate readmissions costs were $23.3 ± 1.5 million USD (n = 2289). CONCLUSION OUD contributes significantly to increased readmission risk in patients with AECP, with significant downstream healthcare costs. Measures against OUD in these patients, such as alternative pain-control therapies, may potentially alleviate such increase in health-care resource utilization.

Acute pancreatitis: Trends in outcomes and the role of acute kidney injury in mortality- A propensity-matched analysis. Pancreatology 2018; 18:870-877. [PMID: 30337224 DOI: 10.1016/j.pan.2018.10.002] [Citation(s) in RCA: 31] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Revised: 10/01/2018] [Accepted: 10/04/2018] [Indexed: 12/11/2022]
Abstract
OBJECTIVES To assess national trends of AP (acute pancreatitis) admissions, outcomes, prevalence of AKI (acute kidney injury) in AP, and impact of AKI on inpatient mortality. METHODS We queried the Nationwide Inpatient Sample database from 2003 to 2012 to identify AP admissions using ICD-9-CM codes. After excluding patients with missing information on age, gender, and inpatient mortality, we used ICD-9-CM codes to identify complications of AP, specifically AKI. We examined trends with survey-weighted multivariable regressions and analyzed predictors of AKI and inpatient mortality by multivariate logistic regression. Additionally, both AKI and non-AKI groups were propensity-matched and regressed against mortality. RESULTS A total of 3,466,493 patients (1.13% of all discharges) were hospitalized with AP, of which 7.9% had AKI. AP admissions increased (1.02%→1.26%) with rise in concomitant AKI cases (4.1%→11.7%) from year 2003-2012. Mortality rate decreased (1.8%→1.1%) in the AP patients with a substantial decline noted in AKI subgroup (17.4%→6.4%) during study period. Length of stay (LOS) and cost of hospitalization decreased (6.1→5.2 days and $13,654 to $10,895, respectively) in AKI subgroup. Complications such as AKI (OR: 6.08, p < 0.001), septic shock (OR: 46.52, p < 0.001), and acute respiratory failure (OR: 22.72, p < 0.001) were associated with higher mortality. AKI, after propensity matching, was linked to 3-fold increased mortality (propensity-matched OR: 3.20, P < 0.001). CONCLUSION Mortality, LOS, and cost of hospitalization in AP has decreased during the study period, although hospitalization and AKI prevalence has increased. AKI is independently associated with higher mortality.

Abstract
BACKGROUND AND AIM Acute kidney injury (AKI) is used as a marker of severity in Clostridium difficile infection (CDI) patients. We estimated the true effect of AKI in inpatient mortality of CDI patients, as there are no large-scale, population-based, propensity-matched studies evaluating AKI's effect in this patient cohort. METHODS A retrospective observational study utilizing the National Inpatient Sample from years 2003 to 2012, including all adults with CDI, excluding cases missing data on age, inpatient mortality or gender. Trends and CDI-related complications as mortality predictors were assessed using survey-weighted multivariable regression. We estimated AKI's independent effect by propensity-matching, post-stratifying by chronic kidney disease status, allowing for multiple comorbidity adjustment. RESULTS A total of 2 859 599 patients with CDI were included, of which 896 122 (31.3%) had principal diagnosis of CDI. AKI prevalence was 22%. Mortality rate was 8.4%, while among AKI patients was higher (18.2%). In multivariable regression, AKI was associated with higher mortality (odds ratio [OR] = 3.16, 95% confidence interval [CI]: 3.02-3.30; P < 0.001), while after propensity matching, AKI increased mortality by 86% (OR = 1.86, 95% CI: 1.79-1.94; P < 0.001). CDI incidence increased by 1.8, together with the rate of AKI (12.6% in 2003 to 28.8% in 2012, P-trend < 0.001). Despite increasing hospitalizations, mortality over the study period decreased to 7.2% (2012) from 9.0% (2003); P-trend < 0.001. CONCLUSION Hospital admissions of patients with CDI and concomitant AKI are increasing, but their inpatient mortality has improved over the study period. AKI is a significant contributor to mortality, independently of other comorbidities, complications, and hospital characteristics, emphasizing the need for early diagnosis and aggressive management in such patients.

Prevention of Aortic Dissection Suggests a Diameter Shift to a Lower Aortic Size Threshold for Intervention. Cardiology 2018; 139:139-146. [DOI: 10.1159/000481930] [Citation(s) in RCA: 46] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2017] [Accepted: 10/02/2017] [Indexed: 12/14/2022]
Abstract
Background: Multiple studies have quantified the relationship between aortic size and risk of dissection. However, these studies estimated the risk of dissection without accounting for any increase in aortic size from the dissection process itself. Objectives: This study aims to compare aortic size before and after dissection and to evaluate the change in size consequent to the dissection itself. Methods: Fifty-five consecutive patients (29 type A; 26 type B) with aortic dissection and incidental imaging studies prior to dissection were identified and compared to a control group of aneurysm patients (n = 205). The average time between measurement at and prior to dissection was 1.7 ± 1.9 years (1.9 ± 2.0 years mean inter-image time in the control group). A multivariate regression model controlling for growth rate, age, and gender was created to estimate the effect of dissection itself on aortic size. Results: The mean aortic sizes at and prior to dissection were 54.2 ± 7.0 and 45.1 ± 5.7 mm for the ascending aorta, and 47.1 ± 13.8 and 39.5 ± 13.1 mm for the descending aorta, respectively. The multivariable analysis revealed a significant impact of the dissection itself (p < 0.001) and estimated an increase in size of 7.65 mm (ascending aorta) and 6.38 mm (descending aorta). Thus, a proportional estimate of 82.8% (ascending aorta) and 80.8% (descending aorta) of dissections are made at a size lower than the guideline-recommended threshold (55 mm). Conclusions: The aortic diameter increases substantially due to aortic dissection itself and, thus, aortas are being dissected at clinically meaningfully smaller sizes than natural history analyses have previously suggested. These findings have important implications regarding the size at which the risk of dissection is increased.

Height alone, rather than body surface area, suffices for risk estimation in ascending aortic aneurysm. J Thorac Cardiovasc Surg 2017; 155:1938-1950.

Abstract
BACKGROUND In international guidelines, risk estimation for thoracic ascending aortic aneurysm (TAAA) is based on aortic diameter. We previously introduced the aortic size index (ASI), defined as aortic size/body surface area (BSA), as a predictor of aortic dissection, rupture, and death. However, weight might not contribute substantially to aortic size and growth. We seek to evaluate the height-based aortic height index (AHI) versus ASI for risk estimation and revisit our natural history calculations. METHODS Aortic diameters and long-term complications of 780 patients with TAAA were analyzed. Growth rate estimates, yearly complication rates, and survival were assessed. Risk stratification was performed using regression models. The predictive value of AHI and ASI was compared. RESULTS Patients were stratified into 4 categories of yearly risk of complications based on their ASI and AHI. ASIs (cm/m2) of ≤2.05, 2.08 to 2.95, 3.00 to 3.95 and ≥4, and AHIs (cm/m) of ≤2.43, 2.44 to 3.17, 3.21 to 4.06, and ≥4.1 were associated with a 4%, 7%, 12%, and 18% average yearly risk of complications, respectively. Five-year complication-free survival was progressively worse with increasing ASI and AHI. Both ASI and AHI were shown to be significant predictors of complications (P < .05). AHI categories 3.05 to 3.69, 3.70 to 4.34, and ≥4.35 cm/m were associated with a significantly increased risk of complications (P < .05). The overall fit of the model using AHI was modestly superior according to the concordance statistic. CONCLUSIONS Compared with indices including weight, the simpler height-based ratio (excluding weight and BSA calculations) yields satisfactory results for evaluating the risk of natural complications in patients with TAAA.

Abstract
OBJECTIVES The nationwide prevalence of cannabis use/abuse has more than doubled from 2002 to 2011. Whether the outpatient trend is reflected in the inpatient setting is unknown. We examined the prevalence and incidence of cannabis abuse/dependence as determined by discharge coding in a 10-year (2002-2011) National Inpatient Sample, as well as various trends among demographics, comorbidities, and hospitalization outcomes. METHODS Cannabis abuse/dependence was identified on the basis of International Classification of Diseases, 9th Revision, Clinical Modification codes 304.3* and 305.2* in adults aged 18 years or more. We excluded cases coded "in remission." National estimates of trends and matched-regression analyses were conducted. RESULTS Overall, 2,833,567 (0.91%) admissions with documented cannabis abuse/dependence were identified, patients had a mean age of 35.12 ± 0.06 years, 62% were male, and there was an increasing trend in prevalence from 0.52% to 1.34% (P <.001). The mean Charlson Comorbidity Index was 0.47 ± 0.006, and inpatient mortality was 0.41%. All of the above demonstrated an increasing trend (P <.001). Mean length of stay was 6.23 ± 0.06 days. The top primary discharge diagnoses were schizoaffective/mood disorders, followed by psychotic disorders and alcoholism. Asthma prevalence in nontobacco smokers had a steeper increase in the cannabis subgroup than in the noncannabis subgroup (P = .002). Among acute pancreatitis admissions, cannabis abusers had a shorter length of stay (-11%) and lower hospitalization costs (-7%) than nonabusers. CONCLUSION Cannabis abuse/dependence is on the rise in the inpatient population, with an increasing trend toward older and sicker patients with increasing rates of moderate to severe disability. Psychiatric disorders and alcoholism are the main associated primary conditions. Cannabis abuse is associated with increased asthma incidence in nontobacco smokers and decreased hospital resource use in acute pancreatitis admissions.

Abstract
BACKGROUND Operative choices for aortic root disease include traditional root replacement with a composite valved graft as well as various valve-sparing and root repair procedures. OBJECTIVES To report our experience with traditional composite graft aortic root replacement by a single surgeon over a 25-year period in 449 patients, focusing on long-term survival and freedom from late reoperation and adverse events. METHODS The coronary button technique was used in all patients. Mean age was 56.1 ± 14.0 years (range 14-87) with 83% males (373/449). Valve prosthesis was mechanical in 343 (76%) and bioprosthetic in 106 (24%). A modified Cabrol procedure (Dacron coronary graft) was employed in 10% (45/449) and concomitant coronary artery bypass graft in 10.9% (49/449). There were 15.8% (71/449) urgent/emergent and 8.2% (37/449) redo procedures. Survival follow-up was 100%. Mean follow-up was 7.0 ± 5.1 years (range 0.1-24.8). RESULTS Operative mortality occurred in 14 patients (3.1%) and was 2.2% (9/418) in non-dissection and 1.9% (7/361) in elective first-time operations. Stroke and re-exploration for bleeding occurred in nine (2.0%) and 20 (4.5%) patients, respectively. Major late events included bleeding in 2.5% (11/435) and thromboembolism in 1.1% (5/435). At 5, 10, and 20 years, freedom from major events and reoperations on the root were 97.8, 95.4, and 94.39%, and 99.0, 99.0, and 97.9%, respectively. Survival in patients aged <60 years was 92.0, 90.1, and 79.8% at five, 10, and 20 years versus 88.4, 67.9, and 42.6% in patients aged ≥60 years (p = 0.001). Compared with age- and gender-matched controls, survival was not significantly different (p = 0.20). CONCLUSIONS Composite graft aortic root replacement is associated with low operative risk, excellent long-term survival, and low incidence of reoperation and late events.

Abstract
OBJECTIVE The purpose of the study was to assess the anticipated incremental risk of a concomitant aortic resection performed with an aortic valve replacement. METHODS Patients who underwent aortic valve replacement with root-sparing ascending replacement were compared with those who underwent isolated aortic valve replacement using propensity score matching (81 pairs; mean age, 63 ± 11 years [root-sparing ascending replacement] vs 64 ± 14 years). To evaluate the impact of the technique at distal site, 71 pairs of those undergoing root-sparing ascending replacement also were matched by propensity score according to distal anastomosis performed clamped and open under deep hypothermic circulatory arrest. RESULTS Operative mortality was equal between the root-sparing ascending replacement and isolated aortic valve replacement groups. No significant difference was found regarding postoperative morbidities, such as bleeding, renal failure, stroke, and length of stay, except prolonged ventilation was found after root-sparing procedures (P = .028). Survival estimation showed no difference between the groups. Comparing the patients undergoing root-sparing ascending replacement with clamped and opened distal anastomosis revealed a prolonged ventilation requirement (7% vs 3%; P = not significant) in the open group. Operative mortality was 0% in both groups, and midterm survival was comparable. CONCLUSIONS The concomitant replacement of the aorta in root-sparing fashion is associated with an excellent operative outcome and adds no additional risk to aortic valve replacement in elective and non-high-risk patients. If the distal anastomosis is performed in an open fashion, while the operative mortality is still very low, morbidities are slightly higher, but midterm survival remains comparable.
