Background: Valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) is associated with improved perioperative safety compared to redo surgical aortic valve replacement (redo-SAVR), but long-term outcomes remain uncertain. We therefore compare long-term outcomes of ViV-TAVR and redo-SAVR.

Methods: The study included 1:1 propensity-matched Medicare beneficiaries with degenerated bioprosthetic valves admitted between 09/29/2011 and 12/30/2020 undergoing either redo-SAVR or ViV-TAVR.

Jun, an Oncological Foe or Friend?

Int J Mol Sci

January 2025

Vascular Biology and Translational Research, Department of Pathology, School of Biomedical Sciences, Faculty of Medicine and Health, University of New South Wales, Sydney, NSW 2052, Australia.

Jun/JUN is a basic leucine zipper (bZIP) protein and a prototypic member of the activator protein-1 (AP-1) family of transcription factors that can act as homo- or heterodimers, interact with DNA elements and co-factors, and regulate gene transcription. Jun is expressed by both immune and inflammatory cells. Jun is traditionally seen as an oncoprotein that regulates processes involved in transformation and oncogenesis in human tumours.

Objective: This study evaluated the effects of bony increased offset (BIO) and metallic augments (MAs) on primary reverse shoulder arthroplasty (RSA) baseplate stability in cadaveric specimens with variable bone densities.

Methods: Thirty cadaveric specimens were analyzed in an imaging and biomechanical investigation. Computed tomography (CT) scans allowed for preoperative RSA planning and bone density analysis.

Importance: Fracture-related infection (FRI) is a serious complication following fracture fixation surgery. Current treatment of FRIs entails debridement and 6 weeks of intravenous (IV) antibiotics. Lab data and retrospective clinical studies support use of oral antibiotics, which are less expensive and may have fewer complications than IV antibiotics.

Division of Endocrinology and Metabolism, Department of Medicine, University of Virginia Health System, Charlottesville, VA.

How effectively preventable cardiovascular disease risk factors such as elevated LDL cholesterol are being mitigated in a real-world U.S. type 1 diabetes population is not well understood, and the demographic factors that are independently associated with elevated LDL cholesterol in this population are not well defined.

The role of serendipity in our investigation of embryo implantation.

Department of Cell Biology, University of Virginia Health System, PO Box 800732, Charlottesville, VA, 22908-0732, USA. Electronic address:

Serendipity plays a huge role in science, and having a prepared mind that can seize upon a chance observation or occurrence can drive a project forward. This happened in my lab with a project centered on the regulation of trophoblast cell behavior at implantation. We discovered that amino acids regulate the onset of trophoblast motility through the activation of the kinase complex mTORC1, and that this acts as a checkpoint to trophoblast differentiation.

Purpose: Research has shown that prolonged endotracheal intubation can increase risk of aspiration following extubation. This study examined the relationship between swallowing and intubation among patients with COVID-19. We investigated the association between the duration of intubation and time until an oral diet was safely initiated and the correlation between the length of intubation and reduced sensation with aspiration as seen on flexible endoscopic evaluation of swallowing (FEES)/videofluoroscopic swallowing study (VFSS).

Background: In Nigeria, trauma care faces challenges due to high injury and death rates from road traffic accidents and violence. Improvements are underway, but gaps in service availability, training, and coordination persist, necessitating evidence-based interventions.

Purpose: To evaluate trauma care practices in Nigeria, focusing on practitioners' perceptions of training, resources, and care quality to inform policy and practice enhancements.

Early initiation of ceftaroline-based combination therapy for methicillin-resistant Staphylococcus aureus bacteremia.

January 2025

Division of Infectious Diseases and International Health, Department of Medicine, University of Virginia Health, Charlottesville, Virginia, USA.

Purpose: Monotherapy with vancomycin or daptomycin remains guideline-based care for methicillin-resistant Staphylococcus aureus bacteremia (MRSA-B) despite concerns regarding efficacy. Limited data support potential benefit of combination therapy with ceftaroline as initial therapy. We present an assessment of outcomes of patients initiated on early combination therapy for MRSA-B.

Background Context: Correcting sagittal malalignment in adult spinal deformity (ASD) is a challenging task, often requiring complex surgical interventions like pedicle subtraction osteotomies (PSOs). Different types of three-column osteotomies (3COs), including Schwab 3, Schwab 4, Schwab 4 with interbody cages, and the "sandwich" technique, aim to optimize alignment and fusion outcomes. The role of interbody cages in enhancing fusion and segmental correction remains unclear.

Purpose: To update previously published clinical and radiographic outcomes of Dejour sulcus-deepening trochleoplasty and medial patellofemoral ligament reconstruction (MPFL-R), at mid-term follow-up, and monitor trends in patient reported outcome scores and satisfaction.

Methods: Using the same cohort of patients from our previously published short-term series of 2-year follow up, interval follow-up was performed on 67 patients (76 knees) with severe trochlear dysplasia and recurrent patellar instability who were prospectively enrolled and underwent Dejour sulcus-deepening trochleoplasty and MPFL-R combined with other patellar-stabilization procedures. Patients with less than 2-year follow-up were excluded.

Hematopoietic stem cell transplantation (HSCT) is a potentially curative therapy for patients with hematologic malignancies and certain solid tumors and nonmalignant hematologic conditions. Both acute kidney injury (AKI) and chronic kidney disease (CKD) occur commonly after HSCT and are associated with significant morbidity and mortality. AKI and CKD in this setting may result from direct effects of the transplant or be caused by pretransplant bone marrow conditioning regimens and/or nephrotoxic agents administered in the post-transplant period.

Introduction: VM202 is a plasmid encoding two isoforms of hepatocyte growth factor (HGF). In preclinical studies, HGF stimulated angiogenesis and muscle regeneration. This preliminary clinical trial tested the hypothesis that VM202 injections in gastrocnemius muscle would improve walking performance in people with mild to moderate and symptomatic lower extremity peripheral artery disease (PAD).

Interplay of fatty acids, insulin and exercise in vascular health.

Lipids Health Dis

January 2025

Division of Endocrinology and Metabolism, Department of Medicine, University of Virginia Health System, Charlottesville, VA, USA.

Fatty acid metabolism, exercise, and insulin action play critical roles in maintaining vascular health, especially relevant in metabolic disorders such as obesity, type 2 diabetes, and cardiovascular disease. Insulin, a vasoactive hormone, induces arterial vasodilation throughout the arterial tree, increasing arterial compliance and enhancing tissue perfusion. These effects, however, are impaired in individuals with obesity and type 2 diabetes, and evidence suggests that vascular insulin resistance contributes to the pathogenesis of type 2 diabetes and its cardiovascular complications.

Immune checkpoint inhibitors (ICIs) have shown promise in the treatment of gastric and oesophageal cancers (GEC). Despite their promising efficacy, ICIs have been associated with unique side effects known as immune-related adverse events (IRAEs). Several studies have shown improved treatment responses in patients with IRAEs compared to those without IRAEs in various cancer types such as melanoma and non-small cell lung cancer.
