    Journal on Big Data, Vol.2, No.1, pp. 1-8, 2020, DOI:10.32604/jbd.2020.01001

    Abstract Water resources are one of the basic resources for human survival, and water protection has been becoming a major problem for countries around the world. However, most of the traditional water quality monitoring research work is still concerned with the collection of water quality indicators, and ignored the analysis of water quality monitoring data and its value. In this paper, by adopting Laravel and AdminTE framework, we introduced how to design and implement a water quality data visualization platform based on Baidu ECharts. Through the deployed water quality sensor, the collected water quality indicator data More >

    Naveed Rabbani1,*, Sarah Hofman DeYoung2, Ronald L. Gibson2, Jeffrey Conwell1, Jason F. Deen1

    Congenital Heart Disease, Vol.15, No.4, pp. 197-201, 2020, DOI:10.32604/CHD.2020.011527

    Abstract Persistent left superior vena cava (PLSVC) is a relatively common congenital venous anomaly that typically drains into the coronary sinus without hemodynamic significance. Rarely a PLSVC drains directly into the left atrium, forming a right-to-left shunt that can result in hypoxemia and potential paradoxical embolism. We present the case of a 2-year-old medically complex child on chronic mechanical ventilation with eventual diagnosis of episodic hypoxemia due to a PLSVC draining into the left atrium with position-dependent venous flow. The lesion was identified with contrast echocardiography and cardiac MRI. Subsequent occlusion with a vascular plug resulted More >

    Congenital Heart Disease, Vol.15, No.4, pp. 181-195, 2020, DOI:10.32604/CHD.2020.012097

    Abstract Objectives: The Fontan operation has increased survival in patients with single-ventricle congenital heart defects. However, Fontan survivors are at risk of other organ dysfunctions, such as renal dysfunction (RD). The objectives of this study are to assess the prevalence of and potential risk factors for RD among Fontan survivors. Design, setting, and patients: We performed a two-center, cross-sectional study that included Fontan survivors evaluated in outpatient-clinics for routine follow up between 01/08-12/16. Outcome measures: The primary outcome was the presence of RD defined by estimated glomerular filtration rate (eGFR) of <90 ml/min/1.73 m2 derived using the serum… More >

    Congenital Heart Disease, Vol.15, No.4, pp. 239-249, 2020, DOI:10.32604/CHD.2020.011576

    Abstract Objective: To test the hypothesis that circulating miRNAs-146a, -146b, -155, and -21 reflect the inflammatory state of children following heart surgery, and that they may, therefore, correlate with postoperative parameters. We aimed to quantify miRNAs in blood samples from pediatric patients before and 6, 12, and 24 hours after surgery and to evaluate correlations between the miRNA levels and the postoperative course. Setting: PICU. Patients: Forty-two pediatric patients with CHD who underwent cardiac surgery at Safra Children’s Hospital between 2012–2016. Interventions: none. Outcome Measures: The primary outcomes were the postoperative cardiac complications and the secondary outcomes were the More >
