    Abstract The Atmospheric Radionuclide Transport Model (ARTM) operates at the meso-γ-scale and simulates the dispersion of radionuclides originating from nuclear facilities under routine operation within the planetary boundary layer. This study presents the extension and validation of this Lagrangian particle dispersion model and consists of three parts: i) a sensitivity study that aims to assess the impact of key input parameters on the simulation results; ii) the evaluation of the mixing prop- erties of five different turbulence models using the well-mixed criterion; and iii) a comparison of model results to airborne observations of carbon dioxide (CO 2 ) emissions from a power plant and the evaluation of related uncertainties. In the sensitiv- ity study, we analyse the effects of stability class, roughness length, zero-plane displacement factor and source height on the three-dimensional plume extent as well as the distance between source and maximum concentration at the ground. The results show that the stability class is the most sensitive input parameter as expected. The five turbulence models are the default turbu- lence models of ARTM 2.8.0 and ARTM 3.0.0, one alternative built-in turbulence model of ARTM and two further turbulence models implemented for this study. The well-mixed condition tests showed that all five turbulence models are able to preserve an initially well-mixed atmospheric boundary layer reasonably well. The models deviate only 6 % from the expected uniform concentration below 80 % of the mixing layer height except for the default turbulence model of ARTM 3.0.0 with deviations by up to 18 %, respectively. CO 2 observations along a flight path in the vicinity of the lignite power plant Bełchatów, Poland measured by the DLR Cessna aircraft during the CoMet campaign in 2018 allow to evaluate the model performance for the different turbulence models under unstable boundary layer conditions. All simulated mixing ratios are in the same order of magnitude as the airborne in situ data. An extensive ...

    Abstract Abstract: Congenital cardiac comorbidities represent a potentially elevated risk for complications in patients undergoing cleft lip repair. National databases, such as the National Surgical Quality Improvement Program Pediatric (NSQIP-P) allow for analysis of large national datasets to assess these risks and potential complications. The aim of this study is to assess the risk of complications in patients undergoing cleft lip repair with congenital cardiac co-morbidities using the NSQIP-P.The 2012 to 2014 NSQIP-P databases were queried for patients undergoing cleft lip repair. Data abstracted for analysis included demographic, clinical, and outcomes data. Patients with cleft lip were stratified based on the presence or absence of congenital cardiac comorbidities. Univariate analysis and step-wise, forward logistic regression were performed to compare these groups.Nationally, between 2012 and 2014, 2126 patients underwent cleft lip repair, 227 with cardiac disease, and 1899 without cardiac disease. Weights were similar between the groups at the time of surgery, though patients with cardiac comorbidities were older. Postoperatively, cardiac disease patients were more likely to experience an adverse event. Specifically, they were more likely to experience reintubation, reoperation, longer length of stay, and death. Rates of surgical site infection and dehiscence were not different between the groups.This study demonstrates that cleft lip repair in patients with congenital heart defects is safe. However, patients undergoing cleft lip repair with comorbid congenital cardiac disease were more likely to experience adverse events. Cardiac patients require special preoperative evaluation before repair of their cleft lip, but do not appear to experience worse wound-related outcomes.

    Abstract Arterial cannulation with a chimney polytetrafluoroethylene graft to the innominate artery is commonly used for antegrade cerebral perfusion during neonatal aortic arch surgery. When properly retained and prepared before sternal closure, resuscitation of the polytetrafluoroethylene graft to innominate artery can be performed months later during sternal reentry. It is a safe and reproducible technique for expeditious arterial cannulation at stage II palliation in single-ventricle patients or complete intracardiac repair of biventricular lesions. We report our experience utilizing this technique successfully during reoperation in 90 of 92 patients, with no adverse thromboembolic events identified.

    Abstract Objective: To assess the risk of complication in patients undergoing cleft palate repair with congenital cardiac comorbidities in a large, national cohort.
    Design: Retrospective review.
    Patients/setting: Using the 2012-2014 National Surgical Quality Improvement Program (NSQIP) Pediatric database, patients undergoing cleft palate repair were selected for analysis. Patients with cleft palate repairs were stratified based on the presence or absence congenital cardiac comorbidities. Univariate and stepwise forward logistic regression were conducted.
    Main outcome measures: It is hypothesized that risk of postoperative adverse events in patients with congenital cardiac comorbidities is higher than in patients without cardiac disease.
    Results: Nationally, between 2012 and 2014, 3240 patients underwent cleft palate repair, 422 (13.0%) with cardiac disease, and 2818 (87.0%) without cardiac disease. Patients with cardiac disease were smaller (10.5 [6.6] kg vs 11.6 [8.6] kg, P < .01) and more likely to be premature (4.6% vs 13.0%, P < .01) compared to those without cardiac disease. Postoperatively, patients with cardiac conditions were more likely to experience an adverse event (8.8% vs 4.2%, P < .01). Specifically, they were more likely to experience reintubation (1.7% vs 0.4%, P < .01), reoperation (2.1% vs 0.6%, P < .01), and longer length of stay (2.7 [7.0] vs 1.6 [2.8] days, P < .01). Rates of surgical site infection and dehiscence were not different.
    Conclusions: Cleft palate repair in patients with concurrent congenital cardiac defects is a safe procedure but carries elevated risk in the postoperative period as demonstrated in this analysis of the NSQIP-Pediatric database. Technical risks are equivalent. Additional anesthesia and surgical awareness of these potential complications is essential to minimize perianesthesia risks.

    Abstract Objective: Children with single ventricle cardiac physiology (SVC) often require airway procedures as an adjunct to their care. Descriptive analysis with a focus on outcomes of airway procedures in SVC patients have not been fully described in the literature.
    Methods: Retrospective, single-center cohort review of 270 patients born between Aug-2007 and Jan-2017. Patients were identified by cardiac database for single ventricle pathophysiology. A subset of these patients were identified to have been evaluated by otolaryngology with airway evaluations and/or interventions.
    Results: 88/270 patients (32.6%) required investigation or intervention for airway pathology. The most frequent procedure was flexible fiberoptic laryngoscopy (58/88 patients); it was the only procedure performed in 40 patients. Seventeen patients required tracheostomies with an associated increased length of stay (p < 0.001). Patients with cardiac procedures involving dissection around the aortic arch were considered higher airway risk due to the threat of recurrent laryngeal nerve injury, and were more likely to have vocal cord paralysis (58%) compared to patients with lower risk procedures (21%; p < 0.001). However, on multivariate logistic regression, vocal cord paralysis did not statistically impact the odds for tracheostomy placement, although the presence of subglottic stenosis increased the odds ratio of tracheostomy by 14.7 (p = 0.02).
    Conclusions: Children with SVC often require airway evaluation and intervention. Patients with high risk cardiac procedures had a higher risk of recurrent laryngeal nerve injury but the presence of subglottic stenosis was the best predictor for a tracheostomy. This study represents one of the largest series of SVC children evaluated for airway pathology.

    Abstract Background: Chylothorax is a rare complication of pediatric cardiac operations that occurs more frequently in children with Noonan syndrome, a genetic disorder associated with cardiac defects and lymphatic anomalies.
    Case presentation: We report a case of postoperative chylothorax in a 6-month-old infant with Noonan syndrome where multimodality lymphatic imaging guided management was followed. Drainage patterns of the lymphatic capillaries in the lower and upper extremities were visualized during near-infrared fluorescence lymphatic imaging (NIRFLI). Dynamic magnetic resonance lymphangiography (MRL) further identified the site of leakage in the thoracic duct and subsequently guided surgical intervention.
    Conclusions: Application of multimodality imaging allows for greater individualization of treatment and should be considered in patients with complex cases such as those with syndromes associated with a higher incidence of chylothorax. IRB Number: HSC-MS-13-0754, December 10, 2013.

    Abstract Power plants and large industrial facilities contribute more than half of global anthropogenic CO 2 emissions. Quantifying the emissions of these point sources is therefore one of the main goals of the planned constellation of anthropogenic CO 2 monitoring satellites (CO2M) of the European Copernicus program. Atmospheric transport models may be used to study the capabilities of such satellites through observing system simulation experiments and to quantify emissions in an inverse modeling framework. How realistically the CO 2 plumes of power plants can be simulated and how strongly the results may depend on model type and resolution, however, is not well known due to a lack of observations available for benchmarking. Here, we use the unique data set of aircraft in situ and remote sensing observations collected during the CoMet (Carbon Dioxide and Methane Mission) measurement campaign downwind of the coal-fired power plants at Bełchatów in Poland and Jänschwalde in Germany in 2018 to evaluate the simulations of six different atmospheric transport models. The models include three large-eddy simulation (LES) models, two mesoscale numerical weather prediction (NWP) models extended for atmospheric tracer transport, and one Lagrangian particle dispersion model (LPDM) and cover a wide range of model resolutions from 200 m to 2 km horizontal grid spacing. At the time of the aircraft measurements between late morning and early afternoon, the simulated plumes were slightly (at Jänschwalde) to highly (at Bełchatów) turbulent, consistent with the observations, and extended over the whole depth of the atmospheric boundary layer (ABL; up to 1800 m a.s.l. (above sea level) in the case of Bełchatów). The stochastic nature of turbulent plumes puts fundamental limitations on a point-by-point comparison between simulations and observations. Therefore, the evaluation focused on statistical properties such as plume amplitude and width as a function of distance from the source. LES and NWP models showed similar performance and ...

    Abstract All-terrain vehicle (ATV) accidents leading to severe morbidity and mortality are common. At our institution, 2 children presented within weeks of each other after ATV accidents. Both children required cardiac valve surgery. The surgical management of these 2 children is discussed, and the literature is reviewed. On initial patient presentation, the diagnosis of a ruptured cardiac valve or ventricular septal defect (VSD) associated with these types of accidents is often delayed. We propose that patients presenting with evidence of high-energy blunt thoracic trauma after an ATV accident should undergo an electrocardiogram, cardiac enzyme assessment, and cardiac echocardiogram as part of the initial work-up to rule out significant myocardial injury.
