BACKGROUND AND OBJECTIVES: Annual incidence of venous thromboembolism (VTE) including postoperative VTE in hospitalized children is rising significantly. A growing body of evidence supports the role of red blood cells (RBCs) in pathologic thrombosis. In this study, we examined the association of perioperative RBC transfusion with postoperative VTE in pediatric patients. METHODS:The pediatric databases of the American College of Surgeons' National Surgical Quality Improvement Project from 2012 to 2017 were used. Multivariable logistic regression was used to examine the association between perioperative RBC transfusion status and the development of new or progressive VTE within 30 days of surgery. The analyses were age stratified, as follows: neonates (#28 days), infants (.28 days and ,1 year), and children ($1 year).RESULTS: In this study, we included 20 492 neonates, 79 744 infants, and 382 862 children. Postoperative development of VTE was reported in 99 (0.48%) neonates, 147 (0.2%) infants, and 374 (0.1%) children. In all age groups, development of VTE was significantly more common among patients with a perioperative RBC transfusion than patients without a perioperative RBC transfusion (neonates: adjusted odds ratio [aOR] = 4.1, 95% confidence interval [CI] = 2.5-6.7; infants: aOR = 2.4, 95% CI = 1.7-3.6; children: aOR = 2.2, 95% CI = 1.7-2.9). Among children who received an intra-or postoperative transfusion, the weightbased volume of RBCs (mL/kg) transfused was associated with postoperative VTE in a dosedependent manner: second tertile (odds ratio = 2.3, 95% CI = 1.3-4.1) and third tertile (odds ratio = 4.1, 95% CI = 2.3-7.4) versus first tertile.CONCLUSIONS: Perioperative RBC transfusions are independently associated with development of new or progressive postoperative VTE in children, infants, and neonates. These findings need further validation in prospective studies and emphasize the need for evidence-based perioperative pediatric blood transfusion decisions.WHAT'S KNOWN ON THIS SUBJECT: Annual incidence of venous thromboembolism (VTE) including postoperative VTE in hospitalized children is rising significantly. A growing body of evidence supports the role of red blood cells in physiologic hemostasis as well as pathologic thrombosis.WHAT THIS STUDY ADDS: In this prospective registry study of .480 000 children, perioperative red blood cell transfusions were associated with higher odds of VTE within 30 days of a surgery in neonates, infants, and children, with a potential dose-response relationship among older children.
Per the American Society for Apheresis, therapeutic plasma exchange (TPE) is a Category III indication in the management of immune thrombocytopenia (ITP). This nationally representative study evaluates TPE utilization in hospitalized adults with a primary admission diagnosis of ITP. Hospitalizations with ITP as the primary admitting diagnosis were analyzed from the 2010 to 2014 National Inpatient Sample, the largest all-payer inpatient database in the United States.Univariate and multivariable logistic regressions were used to determine clinical outcomes in ITP patients undergoing TPE. Sampling weights were applied to
Introduction: Colorectal cancer is one of the most common cancers in the United States. Significant disparities exist among racial and ethnic minorities diagnosed with colorectal cancer compared to non-Hispanic Whites. However, understanding of survival outcomes following curative surgical resection in this population is limited.Objective: To evaluate the association between race and colorectal cancer-specific mortality in patients who were treated with major surgical resection of the colon.Materials and Methods: This study was a retrospective cohort analysis using the Surveillance, Epidemiology, and End Results (SEER) Program database from 2010 to 2016. The patient population consisted of adult patients (≥18 years old) diagnosed with a primary malignancy of colorectal cancer treated with major surgical resection of the colon. The main outcome measures were survival time at one and five years following diagnosis and cancer-specific death.Results: A total of 120,598 patients with primary colorectal malignancy treated with surgical resection of the colon were identified. Across all racial groups, most patients presented with moderately differentiated colorectal cancer. Non-Hispanic Blacks had the highest proportion of diffuse metastases (p<0.001). After adjusting for covariates, Hispanic respondents had the lowest one-year survival (adjusted HR: 1.26, 95%CI (1.21-1.31) and five-year survival when compared to Whites (adjusted HR: 1.13, 95%CI: 1.10-1.15). Factors associated with a shorter survival include age ≥ 70 years old, unmarried status, metastatic disease, and highgrade tumors (p<0.001).Conclusions: Racial disparities exist in the overall survival of patients with colorectal cancer who are treated with surgical resection of the colon. Hispanic patients had the highest hazard of death, followed by Non-Hispanic Asian-Pacific Islanders and Non-Hispanic Blacks, compared to Whites. While surgical resection can be curative, the quality and accessibility of post-operative care may differentiate survival outcomes among racial groups.
