Use of saphenous vein to reimplant intercostal arteries during thoraco-abdominal aortic replacement.

Spinal cord ischemia (SCI) is a major debilitating complication of thoraco-abdominal aortic aneurysm (TAAA) repair, even in experienced centers. Several strategies are employed to reduce the incidence of SCI and the resultant paraplegia, yet the optimum method is unknown. We describe our experience of using the reversed saphenous vein graft (RSVG) as a conduit to reimplant the intercostal arteries (ICAs).

Diverse priming outcomes under conditions of very rare precursor B cells.

Rare B cells can have special pathogen-recognition features giving them the potential to make outsized contributions to protective immunity. However, rare naive B cells infrequently participate in immune responses. We investigated how germline-targeting vaccine antigen delivery and adjuvant selection affect priming of exceptionally rare BG18-like HIV broadly neutralizing antibody-precursor B cells (~1 in 50 million) in non-human primates.

Dose-dependent regulation of immune memory responses against HIV by saponin monophosphoryl lipid A nanoparticle adjuvant.

The induction of durable protective immune responses is the main goal of prophylactic vaccines, and adjuvants play an important role as drivers of such responses. Despite advances in vaccine strategies, a safe and effective HIV vaccine remains a significant challenge. The use of an appropriate adjuvant is crucial to the success of HIV vaccines.

A Valved Expanded Polytetrafluoroethylene Conduit can Acquire Endothelium After Implantation.

We demonstrate histopathology, neointimal proliferation, and neo-endothelialization in an explanted valved expanded polytetrafluoroethylene (ePTFE) conduit 40 months postimplantation that was void of calcification and inflammation, confirmed by CD-31 positivity on immunohistochemistry. Grossly, there was no distortion with preserved leaflets and lack of calcification. Good biocompatibility, nonreactivity, and low antigenicity, combined with neointimal and endothelial layer generation within the conduit might explain the low infection rates and minimal thrombogenicity.

Modulation of type I interferon responses potently inhibits SARS-CoV-2 replication and inflammation in rhesus macaques.

Type I interferons (IFN-I) are critical mediators of innate control of viral infections but also drive the recruitment of inflammatory cells to sites of infection, a key feature of severe coronavirus disease 2019. Here, IFN-I signaling was modulated in rhesus macaques (RMs) before and during acute SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection using a mutated IFN-α2 (IFN-modulator; IFNmod), which has previously been shown to reduce the binding and signaling of endogenous IFN-I. IFNmod treatment in uninfected RMs was observed to induce a modest up-regulation of only antiviral IFN-stimulated genes (ISGs); however, in SARS-CoV-2-infected RMs, IFNmod reduced both antiviral and inflammatory ISGs.

Background: Scimitar syndrome (SS) comprises of an anomalously draining right pulmonary vein (APV), to the inferior vena cava (IVC), maldevelopment of the right pulmonary artery (RPA), and the right lung, with variable number of aorto-pulmonary collaterals (APC) to the right lung. It can cause pulmonary hypertension if left untreated. Surgical correction is the method of choice.

Preparatory stage of interventional extracardiac Fontan.

The extracardiac Fontan can be completed as an interventional procedure when the preparatory stage for Fontan completion is performed at the time of the bidirectional Glenn operation. In this video tutorial, we present the technique for the preparatory stage of an interventional extracardiac Fontan. The interventional aspect offers the advantage of avoiding a redo sternotomy, which involves the risk of cardiac injury, injury to the mediastinal collaterals due to the single-ventricle physiology, the acquired deranged coagulation that may incur morbidity associated with sternal re-entry, and the problems pertinent to cardiopulmonary bypass and/or cardioplegic arrest in this subset of patients.

Magnetic resonance cholangiopancreatography versus endoscopic ultrasound for diagnosis of choledocholithiasis: an updated systematic review and meta-analysis.

Introduction: Both endoscopic ultrasound (EUS) and magnetic resonance cholangiopancreatography (MRCP) are used for the diagnosis of choledocholithiasis (CDL). Previous studies have shown conflicting results regarding the optimal diagnostic strategy for suspected CDL; hence, this meta-analysis was conducted.

Methods: A comprehensive search of literature from 1990 till April 2022 was done of three databases for studies comparing EUS and MRCP to diagnose CDL.

Completion of an interventional extracardiac Fontan.

The extracardiac Fontan can be completed via transcatheter perforation of the pericardial membrane created during the preparatory stage, thus establishing continuity between the inferior vena cava and the pulmonary artery. This step is followed by deployment of a covered stent to isolate the systemic and pulmonary circuits. The procedure avoids the morbidity associated with cardiac reoperation and is a safe option for patients who present late with prohibitive pulmonary artery pressures in whom primary Fontan completion may not be feasible.

Modulation of type I interferon responses potently inhibits SARS-CoV-2 replication and inflammation in rhesus macaques.

Type-I interferons (IFN-I) are critical mediators of innate control of viral infections, but also drive recruitment of inflammatory cells to sites of infection, a key feature of severe COVID-19. Here, and for the first time, IFN-I signaling was modulated in rhesus macaques (RMs) prior to and during acute SARS-CoV-2 infection using a mutated IFNα2 (IFN-modulator; IFNmod), which has previously been shown to reduce the binding and signaling of endogenous IFN-I. In SARS-CoV-2-infected RMs, IFNmod reduced both antiviral and inflammatory ISGs.
