RESUMEN
Disparities in access to hematopoietic cell transplant (HCT) are well established. Prior studies have identified barriers, such as referral and travel to an HCT center, that occur before consultation. Whether differences in access persist after evaluation at an HCT center remains unknown. The psychosocial assessment for transplant eligibility may impede access to transplant after evaluation. We performed a single-center retrospective review of 1102 patients who underwent HCT consultation. We examined the association between race/ethnicity (defined as Hispanic, non-Hispanic Black, non-Hispanic White, and Other) and socioeconomic status (defined by zip code median household income quartiles and insurance type) with receipt of HCT and Psychosocial Assessment of Candidates for Transplantation (PACT) scores. Race/ethnicity was associated with receipt of HCT (p = 0.02) with non-Hispanic Whites comprising a higher percentage of HCT recipients than non-recipients. Those living in higher income quartiles and non-publicly insured were more likely to receive HCT (p = 0.02 and p < 0.001, respectively). PACT scores were strongly associated with income quartiles (p < 0.001) but not race/ethnicity or insurance type. Race/ethnicity and socioeconomic status impact receipt of HCT among patients evaluated at an HCT center. Further investigation as to whether the psychosocial eligibility evaluation limits access to HCT in vulnerable populations is warranted.
RESUMEN
COVID-19 disease progression can be accompanied by a "cytokine storm" that leads to secondary sequelae such as acute respiratory distress syndrome. Several inflammatory cytokines have been associated with COVID-19 disease progression, but have high daily intra-individual variability. In contrast, we have shown that the inflammatory biomarker γ' fibrinogen (GPF) has a 6-fold lower coefficient of variability compared to other inflammatory markers such as hs-CRP. The aims of the study were to measure GPF in serial blood samples from COVID-19 patients at a tertiary care medical center in order to investigate its association with clinical measures of disease progression. COVID-19 patients were retrospectively enrolled between 3/16/2020 and 8/1/2020. GPF was measured using a commercial ELISA. We found that COVID-19 patients can develop extraordinarily high levels of GPF. Our results showed that ten out of the eighteen patients with COVID-19 had the highest levels of GPF ever recorded. The previous highest GPF level of 80.3 mg/dL was found in a study of 10,601 participants in the ARIC study. GPF levels were significantly associated with the need for ECMO and mortality. These findings have potential implications regarding prophylactic anticoagulation of COVID-19 patients.

BACKGROUND: Transplant center report cards are publicly available and used by regulators, insurance payers, and importantly patients and families. OBJECTIVES: In this study, the authors sought to evaluate the variability in reported public performance ratings of pediatric and adult heart transplant centers. METHODS: Program-specific reports from the Scientific Registry of Transplant Recipients from 2017-2021 were used to evaluate stability, volatility, and reliability of 3 publicly reported ratings: waitlist survival (WS), getting to a faster transplant (FT), and post-transplantation graft failure (GF). RESULTS: There were 112 adult and 55 pediatric centers. Over the study period, nearly all centers (98%) had at least 1 change in rating in at least 1 of the tiers. The average time to the first rating change of any magnitude was 12-18 months for all tiers and centers. For adult centers, the most volatile rating was WS (SD: 0.77), followed by GF (SD: 0.76) and then FT (SD: 0.57). For pediatric centers, the most volatile rating was WS (SD: 0.79), followed by both GF (SD: 0.66) and FT (SD: 0.68), which were equally volatile. All tiers except adult FT had an estimated Fleiss's kappa <0.20, indicating poor agreement/consistency across the study period. In addition, the intraclass correlation coefficient for all tiers was <0.50, indicating poor reliability. CONCLUSIONS: The current 5-tier reporting of transplant center performance is highly volatile and has poor reliability and consistency. Given the unintended and significant negative consequences these reports can have, critical revision of these ratings is warranted.

BACKGROUND: Post-hepatectomy liver failure is a source of morbidity and mortality after major hepatectomy and is related to the volume of the future liver remnant. The accuracy of a clinician's ability to visually estimate the future liver remnant without formal computed tomography liver volumetry is unknown. METHODS: Twenty physicians in diagnostic radiology, interventional radiology, and hepatopancreatobiliary surgery reviewed 20 computed tomography scans of patients without underlying liver pathology who were not scheduled for liver resection. We evaluated clinician accuracy to estimate the future liver remnant for 3 hypothetical major hepatic resections: left hepatectomy, right hepatectomy, and right trisectionectomy. The percent-difference between the mean and actual computed tomography liver volumetry (mean percent difference) was tested along with specialty differences using mixed-effects regression analysis. RESULTS: The actual future liver remnant (computed tomography liver volumetry) remaining after a hypothetical left hepatectomy ranged from 59% to 75% (physician estimated range: 50%-85%), 23% to 40% right hepatectomy (15%-50%), and 13% to 29% right trisectionectomy (8%-39%). For right hepatectomy, the mean future liver remnant was overestimated by 95% of clinicians with a mean percent difference of 22% (6%-45%; P < .001). For right trisectionectomy, 90% overestimated the future liver remnant by a mean percent difference of 25% (6%-50%; P < .001). Hepatopancreatobiliary surgeons overestimated the future liver remnant for proposed right hepatectomy and right trisectionectomy by a mean percent difference of 25% and 34%, respectively. Based on years of experience, providers with <10 years of experience had a greater mean percent difference than providers with 10+ years of experience for hypothetical major hepatic resections, but was only significantly higher for left hepatectomy (9% vs 6%, P = .002). CONCLUSION: A clinician's ability to visually estimate the future liver remnant volume is inaccurate when compared to computed tomography liver volumetry. Clinicians tend to overestimate the future liver remnant volume, especially in patients with a small future liver remnant where the risk of posthepatectomy liver failure is greatest.

BACKGROUND: Lung transplantation is a lifesaving intervention for people with advanced lung disease, but it is costly and resource-intensive. To investigate the cost-effectiveness of lung transplantation as a treatment option in pulmonary disease, we must understand costs attributable to end-of-life hospitalizations for end-stage lung disease. RESEARCH QUESTION: What are the costs associated with end-of-life hospitalizations for people with pulmonary disease, and how have these trends changed over time? STUDY DESIGN AND METHODS: Adults aged 18 to 74 years with hospitalization data in the Cost and Utilization Project National Inpatient Sample data from 2009 to 2019 with a pulmonary disease admission were included in this analysis. Those with a history of lung transplantation were excluded. International Classification of Diseases codes were used to identify pulmonary disease admissions, complications, and procedures and interventions. Total charges were calculated for hospitalizations and stratified by patient status at time of discharge. Trends in charges over time were assessed by demographic and hospital factors. RESULTS: One hundred nine thousand nine hundred twenty-four (4.1%) hospital admissions for pulmonary disease resulted in in-hospital mortality. Those with obstructive lung disease accounted for 94.1% of hospitalizations and 88.1% cases of in-hospital mortality. Estimated costs for end-of-life hospitalizations were $29,981 on average with wide variation in cost by diagnosis and procedure utilization. Inpatient costs were highest for younger people who received more procedures. Among the most expensive admissions, mechanical ventilation accounted for the greatest proportion of interventions. Significant increases in the use of mechanical ventilation, extracorporeal membrane oxygenation, and dialysis occurred over the time period. The rate of hospital transfers increased with a proportionately greater increase across admissions resulting in in-hospital mortality. INTERPRETATION: Costs accrued during end-of-life hospitalizations vary across people but represent a significant health care cost that can be averted for selected people who undergo lung transplantation. These costs should be considered in studies of cost-effectiveness in lung transplantation.

Introduction: Renal allograft hypothermic machine perfusion results in a decreased incidence of delayed graft function compared with static cold storage. Ensuring perfusate temperatures remain within the target range of 4-10â °C may impact delayed graft function rates. Project Aims: To identify whether this target was achieved and, if not, whether higher perfusate temperature was associated with delayed graft function. Design: In this retrospective cohort study, transplanted grafts from deceased donors placed on hypothermic machine perfusion pump from June 2019 to August 2020 were analyzed. Measurements were recovered after 5, 15, 60, and 180â min of perfusion. Univariable and multivariable analyses were performed to identify predictors of delayed graft function. Results: A total of 113 grafts from 94 donors were analyzed. Of these, 21 (19%) developed delayed graft function. On univariable logistic regression, variables associated with delayed graft function included older donor age (OR 1.08, P = .002), higher Kidney Donor Profile Index score (OR 1.03, P = .024), and higher 5-min perfusate temperature (T5 min; OR 1.49, P = .014). A higher T5 min was also associated with delayed graft function in multivariable logistic regression models (OR 1.58, P = .005; OR 1.37, P = .08). Grafts with T5 min >10â °C were more likely to experience delayed graft function than those with T5 min <10â °C (OR 4.5, P = .006). Conclusion: Higher early perfusate temperature was an independent predictor of delayed graft function and may be due to inadequate cooling of the circuit prior to placing grafts on pump. Quality improvement initiatives targeting early perfusate temperatures of ≤10â °C may reduce delayed graft function incidence.

INTRODUCTION: Blood component resuscitation is associated with hypocalcemia (HC) (iCal <0.9 mmol/L) that contributes to coagulopathy and death in trauma patients. It is unknown whether or not whole blood (WB) resuscitation helps mitigate the risk of HC in trauma patients. We hypothesized that calcium homeostasis is maintained and mortality improved in patients who only receive WB. MATERIALS AND METHODS: This is a retrospective review of all adult trauma patients who received WB from July 2018 to December 2020. Variables included transfusions, ionized calcium levels, and calcium replacement. Patients were characterized as follows based on blood products received: WB or WB with other blood components. Groups were compared with respect to HC, correction of HC, 24 h, and inpatient mortality. RESULTS: Two hundred twenty-three patients received WB and met the inclusion criteria. 107 (48%) received WB only. HC occurred in 13% of patients who received more than one WB unit compared to 29% of WB and other blood component patients (P = 0.02). WB patients received less calcium replacement (median 250 mg versus 2000 mg, P < 0.01). HC and total units transfused within 4 h were associated with mortality in the adjusted model. HC significantly increased after 5 units of blood products were transfused, regardless of product type. WB was not protective against HC. CONCLUSIONS: HC and failure to correct HC are significant risk factors for mortality in trauma. Resuscitations with WB only and WB in combination with other blood components are associated with HC especially when more than 5 units of any blood product are transfused. Calcium supplementation should be prioritized in any large volume transfusion, regardless of blood product type.

OBJECTIVE: Patients' ability to judge health change over time has important clinical implications for treatment, but is understudied in longitudinal contexts with meaningful health change. We assess patients' awareness of health change for 5 years following bariatric surgery, and its association with weight loss. METHOD: Participants were part of the Longitudinal Assessment of Bariatric Surgery (N = 2,027). Perceived health change for each year was assessed by comparing it to self-reports of health on the SF-36 health survey. Participants were categorized as concordant when perceived and actual self-reported health change corresponded, and as discordant when they did not correspond. RESULTS: Year-to-year concordance between perceived and actual self-reported health change occurred less than 50% of the time. Discordance between perceived and actual health was associated with weight loss following surgery. Discordant-positive participants who perceived their health change as more positive than was warranted lost more weight post-surgery and thus had lower body mass index scores than concordant participants. Conversely, discordant-negative participants who perceived their health as worse than what was warranted lost less weight post-surgery and thus had higher body mass index scores. CONCLUSIONS: These results suggest that recollection of past health is generally poor and can be biased by salient factors during recall. Clinicians are advised to use caution when retrospective judgments of health are utilized. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

BACKGROUND: Following resection of colorectal liver metastasis, most patients have disease recurrence, most commonly intrahepatic. Although the role of resection in colorectal liver metastasis is well-established, there have been limited investigations assessing the benefit of repeat hepatic resection compared with systemic treatment alone for intrahepatic recurrence. METHODS: A retrospective single-institution cohort study of patients with recurrent colorectal liver metastasis following curative-intent hepatectomy was performed from 2003 to 2019. The oncologic outcomes, including post-recurrence overall survival, were evaluated using Kaplan-Meier and Cox proportional hazards modeling. Patients undergoing repeat hepatic resection were propensity-matched with patients receiving systemic treatment alone based on relevant clinicopathologic variables. RESULTS: There were 338 patients treated with hepatic resection for colorectal liver metastasis over the study period. Liver recurrence was observed in 147 (43%) patients at a median time of 10 months from prior resection, with a median post-recurrence overall survival of 29 months. There were 37 patients managed with repeat hepatic resection; 33 (89%) received perioperative chemotherapy. On propensity matching, there were no significant clinicopathologic differences between 37 patients having repeat hepatic resection and 37 patients treated with systemic treatment alone. Repeat hepatic resection was independently associated with improved 5-year post-recurrence overall survival compared with systemic treatment alone (median overall survival 41 vs 35 months, 5-year overall survival 19% vs 3%, P = .048). CONCLUSION: Disease characteristics of patients with intrahepatic recurrence of colorectal liver metastasis, specifically the number of liver lesions and size of the largest lesion, are most predictive of survival and response to systemic therapy. Patients who recur with oligometastatic liver disease experience improved outcomes and derive benefit from curative-intent repeat hepatic resection with integrated perioperative systemic therapy.

BACKGROUND: This prospective observational cohort study evaluates risk-stratified venous thromboembolism (VTE) screening in injured children. While the reported incidence of VTE is 6% to 10% among critically injured children, there is no standard for screening. Venous thromboembolism may have long-term sequelae in children, including postthrombotic syndrome. METHODS: Patients admitted to a level 1 pediatric trauma center were risk stratified for VTE using a validated prediction algorithm. Children at high risk (risk scores ≥523; i.e., ≥1% risk) received screening duplex ultrasonography. Children at moderate risk (risk scores 410-522; i.e., 0.3-0.99% risk) were screened as a comparison/control. RESULTS: Three-hundred fifty-five children were consecutively risk stratified from October 2019 to May 2021. Forty-seven children received screening duplex ultrasounds: 21 from a high-risk cohort and 26 from a moderate-risk cohort. Four children were diagnosed with VTE in the high-risk cohort compared with seven in the moderate-risk cohort ( p = 0.53). Total incidence of VTE among screened children was 23.4% (11 of 47). Asymptomatic VTE accounted for 81.8% of all events (9 of 11). Fifty-four percent (6 of 11) of VTE were central venous catheter associated. Venous thromboembolism in surviving children resolved by 3 to 6 months with no symptoms of postthrombotic syndrome after 1 year. No cases of VTE were identified in unscreened children, yielding an institutional VTE incidence of 3.1% (11 of 355). DISCUSSION: Risk-stratified screening demonstrates a significant incidence of asymptomatic VTE in injured children. These results may guide reevaluation of prediction algorithms developed from symptomatic VTE risk and longitudinal study of the sequelae of asymptomatic VTE. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

OBJECTIVE: We aimed to examine associations between the oral, fecal, and mucosal microbiome communities and adenoma formation. SUMMARY BACKGROUND DATA: Data are limited regarding the relationships between microbiota and preneoplastic colorectal lesions. METHODS: Individuals undergoing screening colonoscopy were prospectively enrolled and divided into adenoma and nonadenoma formers. Oral, fecal, nonadenoma and adenoma-adjacent mucosa were collected along with clinical and dietary information. 16S rRNA gene libraries were generated using V4 primers. DADA2 processed sequence reads and custom R-scripts quantified microbial diversity. Linear regression identified differential taxonomy and diversity in microbial communities and machine learning identified adenoma former microbial signatures. RESULTS: One hundred four subjects were included, 46% with adenomas. Mucosal and fecal samples were dominated by Firmicutes and Bacteroidetes whereas Firmicutes and Proteobacteria were most abundant in oral communities. Mucosal communities harbored significant microbial diversity that was not observed in fecal or oral communities. Random forest classifiers predicted adenoma formation using fecal, oral, and mucosal amplicon sequence variant (ASV) abundances. The mucosal classifier reliably diagnosed adenoma formation with an area under the curve (AUC) = 0.993 and an out-of-bag (OOB) error of 3.2%. Mucosal classifier accuracy was strongly influenced by five taxa associated with the family Lachnospiraceae, genera Bacteroides and Marvinbryantia, and Blautia obeum. In contrast, classifiers built using fecal and oral samples manifested high OOB error rates (47.3% and 51.1%, respectively) and poor diagnostic abilities (fecal and oral AUC = 0.53). CONCLUSION: Normal mucosa microbial abundances of adenoma formers manifest unique patterns of microbial diversity that may be predictive of adenoma formation.

BACKGROUND: Microbial dysbiosis has been closely linked with colorectal cancer development. However, data is limited regarding the relationship of the mucosal microbiome, adenomatous polyps and dietary habits. Understanding these associations may elucidate pathways for risk stratification according to diet. RESULTS: Patients undergoing screening colonoscopy were included in our prospective, single center study and divided into adenoma or no adenoma cohorts. Oral, fecal, and mucosal samples were obtained. Microbial DNA was extracted, and amplicon libraries generated using primers for the 16S rRNA gene V4 region. Patient and dietary information was collected. Of 104 participants, 44% presented with polyps, which were predominantly tubular adenomas (87%). Adenoma formation and multiple patient dietary and lifestyle characteristics were associated with mucosal microbiome diversity. Lifestyle factors included age, body mass index, adenoma number, and dietary consumption of red meats, processed meats, vegetables, fruit, grain, fermented foods and alcohol. CONCLUSION: In this study we showed associations between dietary habits, adenoma formation and the mucosal microbiome. These early findings suggest that ongoing research into diet modification may help reduce adenoma formation and subsequently the development of CRC.
RESUMEN
BACKGROUND AND OBJECTIVES: Colorectal liver metastasis (CRLM) is a leading cause of morbidity and mortality in patients with colorectal cancer. Hepatic arterial infusion (HAI) chemotherapy has been demonstrated to improve survival in patients with resected CRLM and to facilitate conversion of technically unresectable disease. METHODS: Between 2016 and 2018, n = 22 HAI pumps were placed for CRLM. All patients received systemic chemotherapy concurrently with HAI floxuridine/dexamethasone. Overall survival (OS) and progression-free survival (PFS) were assessed using the Kaplan-Meier method. RESULTS: HAI pumps were placed in seven patients with completely resected CRLM and 15 patients with unresectable disease. Twenty-one patients received HAI floxuridine with a median of 5 total HAI cycles (interquartile range: 4-7). Biliary sclerosis was the most common HAI-related complication (n = 5, 24%). Of the 13 patients treated to convert unresectable CRLM, 3 (23%) underwent hepatic resection with curative intent after a median of 7 HAI cycles (range: 4-10). For all HAI patients, the mean OS was 26.7 months from CRLM diagnosis, while the median PFS and hepatic PFS from pump placement were 9 and 13 months, respectively. CONCLUSION: Concomitant HAI and systemic therapy can be utilized at multidisciplinary programs for patients with advanced CRLM, both in the adjuvant setting and to facilitate conversion of unresectable disease.

BACKGROUND: Carcinoid heart disease (CHD) is a sequela of carcinoid liver metastases (LM). The true prevalence of CHD is unknown due to infrequent screening by transthoracic echocardiography (TTE). Octreotide is believed to protect against new and recurrent CHD, but supporting data are scant. This study determined CHD prevalence and outcomes in patients screened by TTE and treated with octreotide. METHODS: Records of carcinoid patients from 2001 to 2021 were reviewed. Survival was estimated by Kaplan-Meyer curves and compared by log-rank. RESULTS: Among 282 patients screened by TTE, overall survival was lower in CHD (n = 40) versus non-CHD (n = 242) patients (p < 0.001). Despite octreotide therapy, 21 patients developed CHD. Among patients with inoperable LM, survival was lower in CHD patients without valve replacement (VR) (p < 0.001), but similar between CHD patients with VR and non-CHD patients. CHD patients with VR and hepatic cytoreduction had survival similar to CHD patients without VR. CONCLUSION: VR improves survival in CHD patients with inoperable LM. Hepatic cytoreduction after VR should be reserved for carefully selected cases. Our data do not support a protective effect of octreotide.

BACKGROUND: A 2-g bolus of tranexamic acid (TXA) has been shown to reduce 28-day mortality in a randomized controlled trial. This study investigates whether out-of-hospital TXA use is associated with adverse events or unfavorable outcomes in suspected traumatic brain injury (TBI) when intracranial hemorrhage (ICH) is absent on initial computed tomography. METHODS: This study used data from a 2015 to 2017, multicenter, randomized trial studying the effect of the following TXA doses on moderate to severe TBI: 2-g bolus, 1-g bolus plus 1-g infusion over 8 hours, and a placebo bolus with placebo infusion. Of the 966 participants enrolled, 395 with an initial computed tomography negative for ICH were included in this analysis. Fifteen adverse events (28-day incidence) were studied: myocardial infarction, deep vein thrombosis, seizure, pulmonary embolism, acute respiratory distress syndrome, cardiac failure, liver failure, renal failure, cerebrovascular accident, cardiac arrest, cerebral vasospasm, "any thromboembolism," hypernatremia, acute kidney injury, and infection. Other unfavorable outcomes analyzed include mortality at 28 days and 6 months, Glasgow Outcome Scale-Extended score of ≤4 at discharge and 6 months, intensive care unit-free days, ventilator-free days, hospital-free days, and combined unfavorable outcomes. In both study drug groups, the incidence of dichotomous outcomes and quantity of ordinal outcomes were compared with placebo. RESULTS: No statistically significant increase in adverse events or unfavorable outcomes was found between either TXA dosing regimen and placebo. Demographics and injury scores were not statistically different other than two methods of injury, which were overrepresented in the 1-g TXA bolus plus 1-g TXA infusion. CONCLUSION: Administration of either a 2-g TXA bolus or a 1-g TXA bolus plus 1-g TXA 8-hour infusion in suspected TBIs without ICH is not associated with increased adverse events or unfavorable outcomes. Because the out-of-hospital 2-g bolus is associated with a mortality benefit, it should be administered in suspected TBI. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level II.

INTRODUCTION: Preoperative chemotherapy (POC) is often employed for patients with resectable colorectal liver metastasis (CRLM). The time to resection (TTR) following the end of chemotherapy may impact oncologic outcomes; this phenomenon has not been studied in CRLM. METHODS: We queried our institutional cancer database for patients with resected CRLM after POC from 2003 to 2019. TTR was calculated from date of last cytotoxic chemotherapy. Kaplan-Meier analysis and multivariable Cox proportional hazards modeling were used to analyze recurrence-free survival (RFS) and overall survival (OS). RESULTS: We identified n = 187 patients. One hundred twenty-four (66%) patients had a TTR of <2 months, while 63 (33%) had a TTR of ≥2 months. Median follow-up was 36 months. On Kaplan-Meier analysis, patients with TTR ≥ 2 months had shorter RFS (median 11 vs. 17 months, p = 0.002) and OS (median 44 vs. 62 months, p < 0.001). On multivariable analysis, TTR ≥ 2 months was independently associated with worse RFS (hazard ratio [HR] = 1.54, 95% confidence interval [CI] = 1.06-2.22, p = 0.02) and OS (HR = 1.75, 95% CI = 1.11-2.77, p = 0.01). CONCLUSION: TTR ≥ 2 months following POC is independently associated with worse oncologic outcomes in patients with resectable CRLM. We therefore recommend consideration for hepatic resection of CRLM within this window whenever feasible.

INTRODUCTION: Marijuana use has been legalized in several states. It is unclear if marijuana use affects weight loss outcomes or complication rates following bariatric surgery. The purpose of this study was to determine if patients who use marijuana had higher complication rates or lower weight loss compared with non-users. METHODS: All patients at a single institution who underwent primary bariatric surgery between July 2015 and July 2020 at a single institution after the legalization of marijuana within the jurisdiction were included. Data regarding marijuana use, weight and complications were abstracted retrospectively. Differences between groups were evaluated with Wilcoxon Rank-Sum tests and Fisher Freeman Halton test. Trends for marijuana use over time was evaluated with simple linear regression on summary data. RESULTS: 1107 patients met inclusion criteria. 798 (73.3%) were never users, 225 (19.4%) were previous users, and 84 (7.2%) were active users. The proportion of active users and previous users increased over time, with significantly more prior marijuana use reported in more recent years (p = 0.014). Active users had significantly higher pre-procedural BMIs than never users: 48.7 vs. 46.3 (p = 0.03). Any marijuana use (active and previous users) was associated with higher preoperative weight compared to never: 136.4 kg vs. 130.6 kg (p = 0.001). Overall complication rate was low in all groups, and there was no difference in the rates of any complications. Active and previous users tended to lose less weight than never users, but this was not statistically significant (p = 0.17). CONCLUSIONS: Active and prior marijuana users tend to have higher BMIs on presentation, but use was not associated with complications or percent weight loss. The incidence of patient reported marijuana use is increasing in the study population. More studies on the effects of marijuana use in this patient population are warranted.

BACKGROUND: The Ross operation for aortic valve replacement continues to be a controversial option because of concerns related to late autograft dilation and progressive neo-aortic insufficiency. In 2005, the reinforced Ross procedure was described at our institution to address this problem. We aim to analyze the short and mid-term outcomes following this procedure. METHODS: This is a retrospective study of patients who underwent the reinforced Ross operation between 2004 and 2019. A comprehensive chart review was performed. Echocardiograms were independently reviewed by an adult congenital cardiologist. The time to reintervention was evaluated with a Kaplan-Meier curve. Analysis was conducted in JMP 15.1 (SAS Inc., Cary, NC). RESULTS: Twenty-five patients underwent the reinforced Ross operation. Twenty-three patients (92%) had bicuspid aortic valve and the most common indication for surgery was a combination of aortic insufficiency and stenosis (n = 18, 72%). The mean follow-up was 6.1 ± 5.0 years. All patients were alive at the time of follow-up. Six patients (24%), from early in our experience, required subsequent aortic reintervention. Median time to reintervention was 41.8 months (0-81.5 months). Sixteen (64%) patients had less than moderate aortic insufficiency at last follow-up. Additionally, average aortic root measurements remained unchanged. CONCLUSIONS: The reinforced Ross technique was initially proposed as a way to mitigate aortic root dilation seen in the traditional Ross procedure. Our experience suggests an associated learning curve with the majority of aortic reinterventions occurring within the first few years following surgery. Continued follow-up is warranted to assess its long-term durability and functionality.
