Purpose We reviewed all 64 articles ever published by The Congenital Heart Surgeons’ Society (CHSS) Data Center to estimate the academic impact of these peer-reviewed articles. Materials and Methods The Congenital Heart Surgeons’ Society has performed research based on 12 Diagnostic Inception Cohorts. The first cohort (Transposition) began enrolling patients on January 1, 1985. We queried PubMed to determine the number of publications that referenced each of the 64 journal articles generated by the datasets of the 12 Diagnostic Inception Cohorts that comprise the CHSS Database. Descriptive summaries of the data were tabulated using mean with standard deviation and median with range. Results Sixty-four peer-reviewed papers have been published based on the CHSS Database. Fifty-nine peer-reviewed articles have been published based on the 12 Diagnostic Inception Cohorts, and five additional articles have been published based on Data Science. Excluding the recently established Diagnostic Inception Cohort for patients with Ebstein malformation of tricuspid valve, the number of papers published per cohort ranged from 1 for coarctation to 11 for transposition of the great arteries. The 11 articles generated from the CHSS Transposition Cohort were referenced by a total of 111 articles (median number of references per journal article = 9 [range = 0-22, mean = 10.1]). Overall, individual articles were cited by an average of 11 (mean), and a maximum of 41 PubMed-listed publications. Overall, these 64 peer-reviewed articles based on the CHSS Database were cited 692 times in PubMed-listed publications. The first CHSS peer-reviewed article was published in 1987, and during the 35 years from 1987 to 2022, inclusive, the annual number of CHSS publications has ranged from 0 to 7, with a mean of 1.8 publications per year (median = 1, mode = 1). Conclusion Congenital Heart Surgeons’ Society studies are widely referenced in the pediatric cardiac surgical literature, with over 10 citations per published article. These cohorts provide unique information unavailable in other sources of data. A tool to access this analysis is available at: [ https://data-center.chss.org/multimedia/files/2022/CAI.pdf ].

Purpose of review Iron overload disorders such as hemochromatosis involve unregulated absorption of dietary iron, leading to excessive iron accumulation in multiple organs. Phlebotomy is the standard of care for removal of excess iron, but dietary modification is not standardized in practice. The purpose of this article is to help standardize hemochromatosis diet counseling based on commonly asked patient questions. Recent findings The clinical benefit regarding dietary modification in iron overload patients is limited due to lack of large clinical trials, but preliminary results are promising. Recent studies suggest diet modification could reduce iron burden in hemochromatosis patients resulting in less annual phlebotomy as supported through small patient studies, concepts of physiology, and animal studies. Summary This article is a guide for physicians to counsel hemochromatosis patients based on commonly asked questions such as foods to avoid, foods to consume, use of alcohol, and use of supplements. The goal of this guide is to help standardize hemochromatosis diet counseling to reduce phlebotomy amount in patients. Standardization of diet counseling could help facilitate future patient studies to analyze the clinical significance.

Background and Aims: Colonoscopies are routinely obtained before liver transplantation, although their utility is a highly debated topic in the literature. We aimed to determine the risk factors in patients with decompensated cirrhosis (DC) for post-colonoscopy complications (PCC). Materials and Methods: We performed a single-center retrospective study of patients with DC undergoing colonoscopy as part of their pre–liver-transplant evaluation. The primary composite outcome was defined as a complication occurring within 30 days of the colonoscopy. Complications included acute renal failure, new or worsening ascites or hepatic encephalopathy, gastrointestinal bleeding, or any cardiopulmonary or infectious complication. Logistic regression analysis was utilized to derive a risk score in predicting the primary composite outcome. Results: The strongest predictors of post-colonoscopy complication were MELD-Na ≥21 [aOR 4.0026 (P=0.0050)] and history of any infection in the 30 days before colonoscopy [aOR 8.4345 (P=0.0093)]. The area under the receiver operating characteristic curve of the final model was 0.78. The predicted risk of any complication at the lowest quartile was 16.2% to 39.4%, and the observed risk was 30.6% (95% CI: 15.5-45.6%), while the predicted risk at the highest quartile was 71.9% to 97.1%, and the observed risk was 81.3% (95% CI: 67.7-95%). Conclusion: In this cohort of patients with DC undergoing colonoscopy for pre–liver-transplant evaluation, a history of ascites, spontaneous bacterial peritonitis, and MELD-Na were found to be predictive of PCC. This risk score may help to predict PCC in patients with DC undergoing a pre-transplant colonoscopy. External validation is recommended.

Abstract Background: Incidentalomas, defined as incidental findings on imaging, are a growing concern. Our aim was to determine the impact and outcomes of extrahepatic incidentalomas on liver transplantation.Methods: Patients at a large liver transplant center, who had an initial MRI for hepatocellular carcinoma screening between January 2004 and March 2020 were identified. Clinical data were collected retrospectively. Survival analysis, utilizing Kaplan Meier estimates and Cox proportional hazards regression analysis, was utilized to determine factors associated with liver transplantation. Results: 720 patients were included. NASH (24.9%), HCV (22.1%) and alcohol (20.6%) were the most common causes of cirrhosis. 79.7% of patients had an extrahepatic incidentaloma. Older age and having received a liver transplant by the end of the study were associated with an incidentaloma. MELD was not associated with the presence of an incidentaloma. On univariate Cox proportional hazards regression, male gender, history of moderate alcohol use, smoking history, MELD, and incidentalomas were predictors of liver transplantation. On multivariate analysis, only MELD and the presence of an incidentaloma were found to be significant. Discovery of an incidentaloma was associated with a 30% increase in the risk of liver transplantation. Median time to transplantation did not differ based on the presence on an incidentaloma. Patients with cirrhosis from alcohol or HCV had a significantly shorter median time to transplantation than those with NASH. Renal and pancreatic lesions comprised 91% of all incidentalomas.Conclusions: In this single-center retrospective study, extrahepatic incidentalomas were common in patients with cirrhosis. The finding of an incidentaloma was associated with a higher risk of liver transplantation despite a similar median time to transplantation if no incidentaloma was discovered.

AbstractBackgroundHypertrophic cardiomyopathy (HCM) presents with a hypertrophied left ventricle (LV). It is often associated with LV outflow tract obstruction (LVOTO) and a risk for sudden death. This study aimed to describe outcomes of patients with HCM who underwent liver transplant (LT).MethodsA retrospective review was conducted for patients diagnosed with HCM undergoing LT. Patient characteristics, preoperative echocardiography results, HCM risk of sudden cardiac death prediction model score, and 5‐year mortality were examined. A univariable Cox proportional hazards model was used to evaluate the association between risk factors and 5‐year mortality. All tests were two‐sided with the alpha level set at .05.ResultsTwenty‐nine patients were included in the analysis. Six patients (21%) had a perioperative cardiopulmonary complication. The 5‐year survival rate was 61% (95% CI, 45–82). The analyzed risk factors showed that 5‐year post‐LT survival was significantly predicted by maximal LV outflow tract gradient at rest > 60 mmHg (hazard ratio, 1.04 [95% CI, 1.01‐1.06]).ConclusionsPreoperative LV outflow tract resting gradient > 60 mmHg was associated with 5‐year post‐LT mortality. The results suggest the severity of LVOTO identified by echocardiography is a prognostic tool for patients with HCM after LT.
