Operative times and outcomes of complex endovascular repairs of thoracoabdominal aneurysms.

Background: Owing to the significant morbidity and mortality of open thoracoabdominal aortic aneurysm surgery, complex endovascular repairs have become increasingly common, but still carry substantial risk. These repairs require large-bore access, with resultant pelvic and lower extremity ischemia. We, therefore, hypothesized that operative timing would be associated with outcomes, because efficient surgery would limit the ischemic time as well as anesthesia time.

Practice patterns in utilization of atherectomy and embolic protection devices in inpatient and outpatient treatment settings.

Objective: The frequency of atherectomy in lower extremity arterial disease has increased substantially over the past several years, specifically in the office-based laboratory (OBL) setting, yet the efficacy compared with other interventions and the consequences of distal embolization remain unknown. Embolic protection devices (EPDs) have been used at varying rates depending on physician and practice setting. Previous studies have described lesion characteristics to consider when weighing the benefits and drawbacks associated with device use.

Combining immunotherapy with high-dose radiation therapy (HDRT) significantly inhibits tumor growth in a syngeneic mouse model of high-risk neuroblastoma.

Purpose: The mortality in patients with -amplified high-risk neuroblastoma remains greater than 50% despite advances in multimodal therapy. Novel therapies are urgently needed that requires preclinical evaluation in appropriate mice models. Combinatorial treatment with high-dose radiotherapy (HDRT) and immunotherapy has emerged as an effective treatment option in a variety of cancers.

Incidence and effects of deep vein thrombosis on the outcome of patients with coronavirus disease 2019 infection.

Background: Deep vein thrombosis (DVT) has been reported to occur at different rates in patients with coronavirus disease 2019 (COVID-19). Limited data exist regarding comparisons with non-COVID-19 patients with similar characteristics. Our objective was to compare the rates of DVT in patients with and without COVID-19 and to determine the effect of DVT on the outcomes.

Weight loss one year after laparoscopic roux-en-Y gastric bypass is not dependent on the type of gastrojejunal anastomosis.

Background: Laparoscopic roux-en-Y gastric bypass (LRYGB) is the gold standard weight-loss procedure. There are different techniques to perform the gastrojejunal (GJ) anastomosis, but there is no consensus as to which one is superior for weight loss. Our goal in this study was to assess one-year weight loss after LRYGB comparing the three different techniques at our tertiary care center.

SARS-Cov-2 Was Not Found in the Peritoneal Fluid of an Asymptomatic Patient Undergoing Laparoscopic Appendectomy.

Background: The safety of laparoscopic surgery in SARS-CoV-2 positive patients remains unclear. The presence of the virus within peritoneal fluid and the peritoneal tissues is not known. We report an asymptomatic COVID-19 positive patient who underwent laparoscopic appendectomy with negative peritoneal sampling for SARS-CoV-2.

Asymptomatic Congenital Lung Malformations: Timing of Resection Does Not Affect Adverse Surgical Outcomes.

Optimal timing for resection of asymptomatic congenital lung malformations (CLMs) remains controversial. The aim of this study is to define optimal timing for surgical intervention of patients with CLMs and define clinical variables that affect surgical outcomes. An IRB-approved retrospective analysis was conducted for patients undergoing surgery for CLMs between 2012 and 2017.

Characterization of Extracorporeal Membrane Oxygenation Support for Single Ventricle Patients.

Background: Extracorporeal membrane oxygenation (ECMO) can provide crucial support for single ventricle (SV) patients at various stages of palliation. However, characterization of the utilization and outcomes of ECMO in these unique patients remains incompletely studied.

Methods: We performed a single-center retrospective review of SV patients between 2010 and 2017 who underwent ECMO cannulation with primary end point of survival to discharge and secondary end point of survival to decannulation or orthotopic heart transplantation (OHT).

Comparative outcomes of right versus left congenital diaphragmatic hernia: A multicenter analysis.

Background: Congenital diaphragmatic hernia (CDH) occurs in 1 out of 2500-3000 live births. Right-sided CDHs (R-CDHs) comprise 25% of all CDH cases, and data are conflicting on outcomes of these patients. The aim of our study was to compare outcomes in patients with right versus left CDH (L-CDH).

Bariatric surgery in patients with left ventricular assist devices: a safe and effective method of weight loss as a gateway to heart transplantation.

Background: Severe cardiac disease often warrants intervention to improve cardiac function, such as mechanical support via a left ventricular assist device (LVAD). While this is an effective way of improving myocardial activity, it works synergistically with weight loss.

Setting: Academic hospital.

Extracorporeal Cardiopulmonary Resuscitation (ECPR) in Infants and Children: A Single-Center Retrospective Study.

Background: Extracorporeal cardiopulmonary resuscitation (ECPR) is increasingly used to rescue patients with cardiac arrest refractory to conventional therapy, necessitating evaluation of factors that may affect outcomes.

Methods: A single-center retrospective review of pediatric patients (<21 years old) who underwent ECPR from January 2010 to November 2017. Comparisons between nonsurvivors and survivors, to decannulation and discharge, were made.

Prevalence of Seizures in Pediatric Extracorporeal Membrane Oxygenation Patients as Measured by Continuous Electroencephalography.

Objectives: Standards for neuromonitoring during extracorporeal membrane oxygenation support do not currently exist, and there is wide variability in practice. We present our institutional experience at an academic children's hospital since establishment of a continuous electroencephalography monitoring protocol for extracorporeal membrane oxygenation patients.

Design: Retrospective, single-center study.

An Analysis of Risk Factors for Hemolysis in Children on Extracorporeal Membrane Oxygenation.

Objectives: Hemolysis is a known complication of pediatric extracorporeal membrane oxygenation associated with renal failure and mortality. We sought to identify predictors of hemolysis in pediatric extracorporeal membrane oxygenation patients and determine its influence on outcomes.

Design: Retrospective, single-center study.
