Photo-Responsive Ascorbic Acid-Modified AgS-ZnS Heteronanostructure Dropping pH to Trigger Synergistic Antibacterial and Bohr Effects for Accelerating Infected Wound Healing.

Nonantibiotic approaches must be developed to kill pathogenic bacteria and ensure that clinicians have a means to treat wounds that are infected by multidrug-resistant bacteria. This study prepared matchstick-like AgS-ZnS heteronanostructures (HNSs). Their hydrophobic surfactants were then replaced with hydrophilic poly(ethylene glycol) (PEG) and thioglycolic acid (TGA) through the ligand exchange method, and this was followed by ascorbic acid (AA) conjugation with TGA through esterification, yielding well-dispersed PEGylated AgS-ZnS@TGA-AA HNSs.

Predictors and Outcomes of Acute Brain Injury in Patients on Venoarterial Extracorporeal Membrane Oxygenation after Cardiopulmonary Resuscitation.

Background: Venoarterial (V-A) extracorporeal membrane oxygenation (ECMO) after cardiac arrest often predisposes patients to acute brain injury (ABI), which affects survival and neurological performance. The investigation of the predictors of ABI will be beneficial for further management.

Objectives: To explore the predictors and outcomes of ABI and intracerebral hemorrhage (ICH) in patients experiencing cardiac arrest and cardiopulmonary resuscitation (CPR) with V-A ECMO support.

Aortic root remodeling after surgical repair of acute type A aortic dissection using different anastomosis techniques.

Background: After surgical repair of acute type A aortic dissection (aTAAD), remodeling of the residual aortic segments is the key outcome parameter associated with late reoperation or aorta-related adverse events. In this study, we analyzed the surgical outcomes of aTAAD using either a telescopic or continuous anastomosis technique, focusing on their impact on aortic root remodeling during the longitudinal follow-up.

Methods: Between 2012 and 2018, 112 surgical repairs of aTAAD with ascending aorta replacement and without aortic arch or aortic root replacement were performed.

Surgical ligation, not transcatheter closure, associated with a higher severity of bronchopulmonary dysplasia in extremely preterm infant intervened for patent ductus arteriosus.

Objective: Patent ductus arteriosus (PDA) is a common complication among premature infants, which may be responsible for prematurity-related complications such as bronchopulmonary dysplasia (BPD). It is unclear whether different interventional methods contribute to the severity of BPD, given the original National Institute of Child Health and Human Development (NICHD) 2001 definition. To date, surgical ligation and the transcatheter approach have been equally successful in premature infants with hemodynamically significant PDA after medical treatment failure.

The aim of this study was to establish this by performing a consensus study.

Methods: The Delphi methodology was used.

The Association of Patent Ductus Arteriosus with Inflammation: A Narrative Review of the Role of Inflammatory Biomarkers and Treatment Strategy in Premature Infants.

Patent ductus arteriosus (PDA) is a common cardiovascular complication that complicates clinical care in the intensive care of premature infants. Prenatal and postnatal infections and the inflammation process can contribute to PDA, and intrauterine inflammation is a known risk factor of PDA. A variety of inflammatory biomarkers have been reported to be associated with PDA.

Synthetic Poly(lactic-co-glycolic Acid) Microvesicles as a Feasible Carbon Monoxide-Releasing Platform for Cancer Treatment.

Biogenic microvesicles (MVs) play a pivotal role in intercellular signal communication, thus initiating critical biological responses such as the proliferation of cancer cells, gene and protein transport, and chemo-drug resistance. In addition, they have been recognized as having great potential in drug delivery applications. However, the productivity of biologically produced MVs is not sufficient for clinical applications.

Potential of Autologous Progenitor Cells and Decellularized Porcine Artery Matrix in Construction of Tissue-engineered Vascular Grafts.

To develop a tissue-engineered vascular graft, we used pericardial effusion-derived progenitor cells (PEPCs) collected from drained fluid after open-heart surgery in children with congenital heart diseases to repopulate a decellularized porcine pulmonary artery. The PEPCs were compared with human fibroblasts (HS68) and human umbilical vein endothelial cells (HUVECs) in cell growth and migration. They were cultured with the matrices via an inner approach (intima), lateral approach (media), and outer approach (adventitia).

Respiratory Trajectory after Invasive Interventions for Patent Ductus Arteriosus of Preterm Infants.

Invasive interventions have been conducted in preterm infants with significant patent ductus arteriosus (PDA) when medical treatment has failed, and methods of invasive intervention have been reported. Surgical ligation via lateral thoracotomy has been a well-established procedure for decades. Recently, transcatheter occlusion has been safely and feasibly applied to the premature population.

Methods: A total of 248 surgical repairs of acute type A aortic dissections were conducted at a tertiary medical center between 2010 and 2018.

Diastolic and systolic right ventricular diameters for predicting pulmonary hypertension in children with congenital heart disease.

Prospective electrocardiography (ECG)-gated cardiac computed tomography angiography (CTA) is widely used for pediatric patients with congenital heart disease (CHD) due to the lower radiation dose compared with the ECG-gated technique. However, functional parameters acquired using ECG-gated cardiac CT to predict pulmonary hypertension (PH) in children with CHD have not yet been reported. This study aimed to investigate the potential of diastolic and systolic right ventricular diameters (RVD) on prospective ECG-gated cardiac CTA to predict PH in children with CHD.

Mitral Valve Replacement Using Subvalvular Apparatus: A Systematic Review and Meta-Analysis.

Background: To assess clinical outcomes among participants undergoing mitral valve replacement with preservation of subvalvular apparatus.

Methods: Electronic databases, including PubMed, Embase, Science Direct, World of Science, Scopus, Biosis, SciElo and Cochrane library, were probed using an extensive search strategy. Studies that reported at least one clinical outcome, such as morbidity, mortality, early 30-day mortality, myocardial failure, survival, late cerebrovascular events, length of stay, or major operative complications (stroke, prolonged ventilation, and reoperation for bleeding, renal failure, and sternal infection) were considered for inclusion.

Post-Coronary Artery Bypass Medications in Dialysis Patients: Do We Need to Change Strategies?

Background: Coronary artery bypass grafting (CABG) is frequently performed in patients with end-stage renal disease (ESRD) together with severe coronary artery disease, after which, patients with ESRD have higher surgical risk and poorer long-term outcomes. We report our experience in patients with ESRD who survived in CABG and identify predictors of long-term outcomes.

Methods: We retrospectively investigated 93 consecutive patients with ESRD who survived to discharge after isolated CABG between January 2005 and December 2016 at our institution.

Progenitor Cells Derived from Drain Waste Product of Open-Heart Surgery in Children.

Human cardiac progenitor cells isolated from the same host may have advantages over other sources of stem cells. The aim of this study is to establish a new source of human progenitor cells collected from a waste product, pericardiac effusion fluid, after open-heart surgery in children with congenital heart diseases. The fluid was collected every 24 h for 2 days after surgery in 37 children.

Improved outcomes from endovascular aortic repair in younger patients: Towards improved risk stratification.

Objectives: Abdominal aortic aneurysms are conventionally treated by open repair surgery. While endovascular aortic repair improves survival in high-risk patients, younger patients (40–65 years) potentially at lower risk with asymptomatic abdominal aortic aneurysms undergoing endovascular aortic repair usually have poorer post-operative outcomes and require longer term follow-up. In this study, clinical data on younger patients were analyzed to investigate whether endovascular aortic repair leads to poorer short- and long-term outcomes.

Application of two-dimensional fractional-order convolution and bounding box pixel analysis for rapid screening of pleural effusion.

Pleural effusion is a pathologic symptom in which there is accumulation of body fluids around the lungs. A chest radiograph is a rapid examination technique and does not require complex setup for making a preliminary diagnosis of lung and heart diseases. In radiographic visualization, the symptom patterns appear as light or dark areas in the lung cavity.
