Abstract Several studies have shown an association between Epstein-Barr virus (EBV) infection and some human cancers such as a subgroup of gastric carcinomas. The oncogenic potential of EBV has been widely explored but the exact processes conducting carcinogenesis are not yet fully understood. EBV-encoded viral proteins are known to deregulate the DNA damage response (DDR) signaling pathways. DDR inactivation leads to genomic instability and promote cellular transformation to generate malignant cells. In a recently published article in Nature Medicine, a molecular characterization of tumor tissue and circulating tumor DNA (cDNA) from non-selected patients with metastatic gastric cancer treated with pembrolizumab was… More >

Abstract Objectives: Pulmonary arterial hypertension in congenital heart disease (PAH-CHD) is the most common type of PAH and increases morbidity and mortality in patients with CHD. Right heart catheterization (RHC) is the standard method to diagnose PAH. However, RHC is an invasive and complicated method with relatively high cost. Noninvasive, feasible, and cost-efficient methods are urgently needed. The objective of this study was to evaluate three potential biomarkers of PAH-CHD: Hepatocyte growth factor (HGF), osteopontin (OPN), and suppression of tumorigenicity 2 (ST2). Methods: Plasma samples were collected from patients with CHD (n = 46) and healthy individuals (n = 22) and… More >

Abstract Amyotrophic lateral sclerosis (ALS), also called Lou Gehrig’s disease, is an irreversible disease that is caused by the degeneration and death of motor neurons. Approximately 5–10% of cases are familial ALS (fALS), and the other cases are sporadic ALS (sALS). Gene mutations have been identified both in fALS and sALS patients. In this study, we discuss the four ALS-related genes, C9orf72, SOD1, FUS, and TARDBP, and review the microRNAs (miRNAs) that are associated with ALS and other neurological disorders from the literature. A phylogenetic analysis is used to explore potential miRNAs that can be taken into account when studying the… More >

Abstract Preoperative chemoradiation therapy (CRT) is becoming the standard treatment for patients with locally advanced rectal cancer. However, individual differences in response to treatment range from a complete response to complete resistance. Predicting the tumor response to radiotherapy may improve the efficacy of radiotherapy. This review mainly summarizes recent studies about the molecular biomarkers that can predict the response to radiotherapy in rectal cancer. These studies have indicated that the molecular markers involved in the response to radiotherapy mainly include genes related to radiosensitivity, cancer stem cell-related markers, non-coding RNAs (ncRNAs), single-nucleotide polymorphisms (SNPs) and gene methylation, and other factors including… More >

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 length of… More >

Abstract Background: There are significant implications for kidney disease in young adults with congenital heart disease. Prior investigations have not focused on the use of urinary tubular biomarkers for the early identification of kidney disease in this growing patient group.
Objective: Determine if young adults with congenital heart disease have differences in the baseline concentration of urinary tubular biomarkers when compared to healthy young adults.
Design/Methods: In a pilot case control study, 30 patients from 18 to 35 years of age with congenital heart disease and a normal serum creatinine were recruited during a routine follow-up visit. In the same age… More >

Abstract Objective: This study aims to investigate the changes in renal function and levels of urinary biomarkers before and after cardiac angiography in children with congenital heart disease (CHD).
Setting: Children with CHD are at a risk for kidney injury during contrast exposure in cardiac angiography.
Outcome Measures: We measured urinary protein, albumin, N‐acetyl‐β‐D‐glucosaminidase (NAG), β2‐microglobulin (BMG), and liver‐type fatty acid‐binding protein (L‐FABP) levels, as well as serum creatinine and cystatin C levels, before and after cardiac angiography in 33 children with CHD.
Results: No significant decrease was noted in either the creatinine‐based or cystatin C‐based estimated glomerular filtration rate at… More >

Abstract Objective: Patients undergoing surgical repair of aortic coarctation have a 50% risk of pathologic left ventricular remodeling (increased left ventricular mass or relative wall thickness). Endothelin 1, ST2, galectin 3, norepinephrine and B‐natriuretic pep‐ tide are biomarkers that have been associated with pathologic LV change in adult populations but their predictive value following pediatric coarctation repair are not known.
Hypothesis: Biomarker levels at coarctation repair will predict persistent left ven‐ tricular remodeling at 1‐year follow up.
Design: Prospective, cohort study of 27 patients’ age 2 days‐12 years with coarcta‐ tion of the aorta undergoing surgical repair. Echocardiograms were performed pre‐… More >

Abstract Objectives: Neonates and infants undergoing surgery for congenital heart disease are at risk for developmental impairment. Hypoxic‐ischemic brain injury might be one contributing factor. We aimed to investigate the perioperative release of the astro‐ cyte protein S100B and its relation to cerebral oxygenation.
Methods: Serum S100B was measured before and 0, 12, 24, and 48 hours after sur‐ gery. Cerebral oxygen saturation was derived by near‐infrared spectroscopy. S100B reference values based on preoperative samples; concentrations above the 75th per‐ centile were defined as elevated. Patients with elevated S100B at 24 or 48 hours were compared to cases with S100B in… More >

Abstract Background: Ideally, vasodilator therapies for pulmonary arterial hypertension (PAH) should have a favorable impact on markers of vascular dysfunction, in addition to their known effects on hemodynamics, cardiac function, and patient’s physical capacity.
Methods: We analyzed circulating (plasma) markers of endothelial and platelet activation/dys‐ function (enzyme‐linked immunoassays) in the specific setting of advanced PAH associated with congenital heart disease, during the course of sildenafil and tadalafil therapies. Thirty‐one patients were enrolled (age 10‐54 years), most of them with chronic hypoxemia and elevated hematocrit. Drugs were administered orally for 6 months (sildenafil [n = 16], 20 mg t.i.d.; tada‐ lafil [n… More >
