Children's Heart Assessment Tool for Transplantation (CHAT) Score: A Novel Risk Score Predicts Survival After Pediatric Heart Transplantation.

Background: Given the shortage of donor organs in pediatric heart transplantation (HTx), pretransplant risk stratification may assist in organ allocation and recipient optimization. We sought to construct a scoring system to preoperatively stratify a patient's risk of one-year mortality after HTx.

Methods: The United Network for Organ Sharing database was queried for pediatric (<18 years) patients undergoing HTx between 2000 and 2016.

-Halogenation Affects Monoamine Transporter Inhibition Properties and Hepatocellular Toxicity of Amphetamines and Methcathinones.

Halogenated derivatives of amphetamine-type stimulants are appearing on the drug market, often with altered pharmacological profile and sometimes different legal status compared to the non-halogenated substances. The aim of the present study was to investigate the pharmacological profile and hepatocellular toxicity of -halogenated amphetamines and cathinones. The potential of amphetamine, 4-fluoroamphetamine, 4-chloroamphetamine, methcathinone, 4-fluoromethcathinone, and 4-chloromethcathinone to inhibit the monoamine transporters for norepinephrine, dopamine, and serotonin was determined in transporter-transfected human embryonic kidney 293 cells.

Outcomes after heart transplantation in sensitized patients bridged with ventricular assist devices.

Objective: Sensitization has been associated with worse outcomes following heart transplantation (HTx). The use of ventricular assist devices (VAD) is a risk factor for the development of sensitization. We investigated the impact of left ventricular assist devices (LVAD) and sensitization in HTx recipients.

Racial Disparities in Patients Bridged to Heart Transplantation With Left Ventricular Assist Devices.

Background: Left ventricular assist devices (LVADs) are an effective therapy in bridging patients with end-stage heart failure to heart transplantation. The aim of this study was to identify the role of race in survival of patients bridged to heart transplantation with a LVAD.

Methods: The United Network of Organ Sharing database was queried for all adult heart transplant recipients (age 18 years or older) who were bridged to transplantation with a LVAD from 2005 to 2018.

Delayed Surgical Management of Type A Intramural Hematoma Is Not Associated with Worse Outcomes Than Emergent Operation.

Objectives: Management of acute aortic intramural hematomas (IMHs) involving the ascending aorta and root remains controversial. Some series have suggested that delaying operative intervention beyond the first 24-hours may be beneficial.

Methods: A retrospective single-institution analysis was performed to identify patients presenting with type A IMH.

Valve-sparing aortic root replacement in children: Outcomes from 100 consecutive cases.

Objective: Valve-sparing root replacement is an attractive alternative to composite mechanical or biologic prostheses for aortic root aneurysms in children. Data on outcomes in pediatric patients are limited. We present our institutional experience with 100 consecutive pediatric valve-sparing aortic root procedures.

Molecular Toxicological Mechanisms of Synthetic Cathinones on C2C12 Myoblasts.

Synthetic cathinones are popular psychoactive substances that may cause skeletal muscle damage. In addition to indirect sympathomimetic myotoxicity, these substances could be directly myotoxic. Since studies in myocytes are currently lacking, the aim of the present study was to investigate potential toxicological effects by synthetic cathinones on C2C12 myoblasts (mouse skeletal muscle cell line).

Impact of Traumatically Brain-Injured Donors on Outcomes After Heart Transplantation.

Background: Heart transplant recipients of traumatically brain-injured (TBI) donors have been reported to have inferior survival and increased rates of cardiac allograft vasculopathy in single-center studies. This study sought to examine the impact of TBI donors on outcomes after heart transplantation across all transplantation centers.

Methods: We identified all adult heart transplants performed during 2007-2016 in the OPTN database.

Variation in Platelet Transfusion Practices in Cardiac Surgery.

Objective: Although the morbidity associated with red blood cell transfusion in cardiac surgery has been well described, the impacts of platelet transfusion are less clearly understood. Given the conflicting results of prior studies, we sought to investigate the impact of platelet transfusion on outcomes after cardiac surgery across institutions in Maryland.

Methods: Using a multiinstitutional statewide database created by the Maryland Cardiac Surgery Quality Initiative, we retrospectively analyzed data from 10,478 patients undergoing isolated coronary artery bypass across 10 centers.

Early Outcomes After Heart Transplantation in Recipients Bridged With a HeartMate 3 Device.

Background: Left ventricular assist devices are increasingly used as bridge-to-transplantation in eligible patients. The HeartMate 3 (HM3; Abbott Laboratories, Abbot Park, IL) is the latest device to obtain US Food and Drug Administration approval as bridge-to-transplantation. This study examines early outcomes of transplant recipients after HM3 in comparison with recipients bridged with the HeartMate 2 (HM2; Abbott Laboratories) and HeartWare Ventricular Assist System (HVAD; Medtronic, Minneapolis, MN) devices.

Comparing Frailty Markers in Predicting Poor Outcomes after Transcatheter Aortic Valve Replacement.

Introduction: Frailty is an important component of risk prognostication in transcatheter aortic valve replacement (TAVR). Objective markers of frailty, including sarcopenia, the modified Frailty Index (mFI), and albumin levels, have emerged, but little is known how such markers compare to each other in predicting outcomes after TAVR. We sought to define and compare these markers in predicting long-term outcomes after TAVR.

Size Mismatching Increases Mortality After Lung Transplantation in Preadolescent Patients.

Background: The effect of size mismatch between donor and recipient in pediatric lung transplantation (PLTx) is currently unknown. Previous studies in adults have suggested that oversized allografts are associated with improved outcomes after lung transplantation. We investigated this relationship to quantify its effect on posttransplant outcomes in children.

Association of preoperative spinal drain placement with spinal cord ischemia among patients undergoing thoracic and thoracoabdominal endovascular aortic repair.

Objective: Spinal cord ischemia (SCI) is among the most devastating complications of thoracic endovascular aortic repair (TEVAR). Spinal fluid drainage has been proposed as a viable means to reduce SCI, but few data exist to support its routine use. This study investigated the association of preoperative spinal fluid drainage with the risk of SCI after TEVAR.

Sparsity-based continuous wave terahertz lens-free on-chip holography with sub-wavelength resolution.

We demonstrate terahertz (THz) lens-free in-line holography on a chip in order to achieve 40 μm spatial resolution corresponding to ~0.7λ with a numerical aperture of ~0.87.

MicroRNA-302c modulates peritoneal dialysis-associated fibrosis by targeting connective tissue growth factor.

Long-term peritoneal dialysis (PD) can lead to the induction of mesothelial/epithelial-mesenchymal transition (MMT/EMT) and fibrosis; these effects eventually result in ultrafiltration failure and the discontinuation of PD. MicroRNA-302c (miR-302c) is believed to be involved in regulating tumour cell growth and metastasis by suppressing MMT, but the effect of miR-302c on MMT in the context of PD is unknown. MiR-302c levels were measured in mesothelial cells isolated from the PD effluents of continuous ambulatory peritoneal dialysis patients.

Cardiac sympathectomy for refractory ventricular tachycardia in arrhythmogenic right ventricular cardiomyopathy.

Background: The sympathetic nervous system plays an important role in arrhythmogenesis in arrhythmogenic right ventricular cardiomyopathy (ARVC). Sudden cardiac death commonly occurs during exertion, and β-blockers are associated with a reduction in arrhythmia burden. Bilateral cardiac sympathetic denervation (BCSD) has been shown to reduce implantable cardioverter-defibrillator (ICD) shocks in patients with structural heart disease and refractory ventricular tachycardia (VT); however, data in ARVC are sparse.

TCR and CD28 Concomitant Stimulation Elicits a Distinctive Calcium Response in Naive T Cells.

T cell activation is initiated upon ligand engagement of the T cell receptor (TCR) and costimulatory receptors. The CD28 molecule acts as a major costimulatory receptor in promoting full activation of naive T cells. However, despite extensive studies, why naive T cell activation requires concurrent stimulation of both the TCR and costimulatory receptors remains poorly understood.

Reduced Cerebrospinal Fluid Inflow to the Optic Nerve in Glaucoma.

Purpose: To determine whether cerebrospinal fluid (CSF) entry into the optic nerve is altered in glaucoma.

Methods: Fluorescent 10-kDa dextran tracer was injected into the CSF of 2-month-old (n = 9) and 10-month-old DBA/2J glaucoma mice (n = 8) and age-matched controls (C57Bl/6; n = 8 each group). Intraocular pressure (IOP) was measured in all mice before tracer injection into CSF.

Wavelength optimization in the multispectral photoacoustic tomography of the lymphatic drainage in mice.

Multispectral photoacoustic tomography provides mapping of the tissue chromophore distributions using sets of tunable laser wavelengths. With the overall goal of studying the dynamics of cerebrospinal fluid in mice in vivo, our work aims to minimize the number of wavelengths to reduce scanning time, improve the temporal resolution, reduce the energy deposition and avoid the tracer photobleaching while maintaining high image quality. To select small sets of wavelengths we directly searched for the combinations of wavelengths providing the best and worst image quality in comparison with a reference image obtained using 131 closely spaced wavelengths between 680 and 940 nm in terms of the peak signal-to-noise ratio (PSNR).

Sub-wavelength tight-focusing of terahertz waves by polarization-independent high-numerical-aperture dielectric metalens.

A focusing device is one of the key elements for terahertz applications, including homeland security, medicine, industrial inspection, and other fields. Sub-wavelength tight-focusing of terahertz waves is attractive for microscopy and spectroscopy. Flat optical lenses based on metasurfaces have shown potential in diffraction-limit focusing and advantages of ultrathin thickness and lightweight for large-aperture optics.

Autologous blood transfusion augments impaired wound healing in diabetic mice by enhancing lncRNA H19 expression via the HIF-1α signaling pathway.

Background: Impaired wound healing frequently occurs in diabetes mellitus (DM) and is implicated in impaired angiogenesis. Long non-coding RNA (lncRNA) H19 has been reported as being reduced in DM and played a critical role in inducing angiogenesis. Thus, we hypothesized that H19 may affect impaired wound healing in streptozotocin (STZ)-induced diabetic mice transfused with autologous blood preserved in standard preservative fluid or modified preservative fluid.
