Functional liquid-infused PDMS sponge-based catheter with antithrombosis, antibacteria, and anti-inflammatory properties. Colloids Surf B Biointerfaces 2023; 224:113208.

Abstract
A functional liquid-infused catheter surface strategy has recently attracted increasing attention for blood transport with the remarkable antibiofouling performance. Nevertheless, constructing porous structure inside a catheter with effective functional liquid-locking ability remains extremely challenging. Herein, the central cylinder mold and sodium chloride particle templates technique was used to create a PDMS sponge-based catheter that stores a stable functional liquid. Our multifunctional liquid-infused PDMS sponge-based catheter can not only exhibit bacterial resistant, less macrophages infiltration, a slighter inflammation response, but also capability to prevent platelet adhesion and activation, and impressively reduce thrombosis in vivo even at high shear. Therefore, these desirable properties will endow the prospective practical applications and serve as a watershed moment in the development of biomedical devices.

Abstract
Abstract
Background
Catheter-related right atrial thrombosis (CRAT) is an under-studied complication of a long-term implantable venous access devices (IVAD), particularly in children with incidence rates extrapolated from the adult literature ranging between 2 and 29%. This is a single-center retrospective review of electronic medical records of children who underwent insertion of IVADs and had at least one echocardiogram performed prior to catheter removal between 2008 and 2018. Data collection included demographic information, development of CRAT, systemic infection, and administration of thrombogenic chemotherapeutic agents. We identified six patients who developed CRAT and compared them to 120 control patients. We also performed a detailed chart review for the patients who developed CRAT. Data was entered and analyzed using SPSS.
Results
A total of 764 patients underwent IVAD placement between 2008 and 2018. Six (0.79%) patients developed CRAT, and 120 patients were identified as controls that match the CRAT patients based on definitive criteria that include age, gender, chemotherapy type, steroid therapy, reason of line insertion, site of catheter insertion, tip-location at insertion, and history of systemic infections. In the CRAT group, 3 (50%) patients had their catheter tips placed in the superior vena cava-right atrial junction and 3 (50%) in the right atrium, whereas in the control group, all patients had their catheter tips placed in the superior vena cava-right atrial junction (p=0.000). Five (83.3%) patients in the CRAT group received L-asparaginase as compared to 75 (62.5%) patients in the control group (p=0.301). In the CRAT group, all patients had a history of systemic infection compared to 47 (39.2%) in the control group (p=0.180).
Conclusion
We identified 6 (0.79%) children with CRAT. Catheter-tip location within the right atrium is a potential risk factor for CRAT development in children.

RESEARCH 2022; 2022:9780879.

Abstract
Thrombosis and infections are the two major complications associated with extracorporeal circuits and indwelling medical devices, leading to significant mortality in clinic. To address this issue, here, we report a biomimetic surface engineering strategy by the integration of mussel-inspired adhesive peptide, with bio-orthogonal click chemistry, to tailor the surface functionalities of tubing and catheters. Inspired by mussel adhesive foot protein, a bioclickable peptide mimic (DOPA)4-azide-based structure is designed and grafted on an aminated tubing robustly based on catechol-amine chemistry. Then, the dibenzylcyclooctyne (DBCO) modified nitric oxide generating species of 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) chelated copper ions and the DBCO-modified antimicrobial peptide (DBCO-AMP) are clicked onto the grafted surfaces via bio-orthogonal reaction. The combination of the robustly grafted AMP and Cu-DOTA endows the modified tubing with durable antimicrobial properties and ability in long-term catalytically generating NO from endogenous s-nitrosothiols to resist adhesion/activation of platelets, thus preventing the formation of thrombosis. Overall, this biomimetic surface engineering technology provides a promising solution for multicomponent surface functionalization and the surface bioengineering of biomedical devices with enhanced clinical performance.

Abstract
Sickle cell disease (SCD), the most common genetic disorder globally, is often associated with an increased risk of venous thromboembolic events (VTE). Many of these patients have central lines placed for the purposes of repeated medication administration, blood transfusions, and blood draw, further increasing the risk of VTE. Given the non-specific presentation of VTE and pulmonary embolism, as well as the risk of mortality if interventions are delayed, a high index of suspicion is required for early diagnosis of the condition. We report the case of a 35-year-old woman with SCD and a port-a-cath in place who presented with extensive upper extremity and intrathoracic VTE with associated pulmonary embolism and chronic superior vena cava (SVC) occlusion. We also discuss the peculiarities of the clinical manifestations and management of VTE and pulmonary embolism in the setting of SCD based on the evidence from existing literature.

Abstract
BACKGROUND Proper tip position is a major determinant of totally implantable venous access device (TIVAD) outcome. The aim of this study is to analyze the potential utilization of intravenous electrocardiography (IV-ECG) to help inexperienced operators for TIVAD placement. PATIENTS AND METHODS This is a retrospective, observational, uni-institutional study. 331 patients receiving TIVAD implantation from July 2008 to December 2008 were recruited. In IV-ECG group, IV-ECG was used to help decide catheter tip location and catheter length. In Landmark group, catheter length was decided by surface landmarks. Catheter tip position was confirmed by post-operative supine chest X-ray. RESULTS There were 153 patients in IV-ECG group, and 178 patients in Landmark group. No immediate reoperation due to catheter mal-position was noted in IV-ECG group, but it happened in eight patients in Landmark group. In IV-ECG group, 97.3% of the catheter tip located at proper position (within 2 cm from junction of right atrium and superior vena cava, as compared to 88.8% of the tip position in Landmark group was proper. The difference was statistically significant (P < 0.05). There was no complication associated with the use of IV-ECG. CONCLUSION IV-ECG is a safe and convenient method to help inexperienced operators placing TIVAD.
