Assessing Right Ventricle Over Time in Patients on Veno-Venous Extracorporeal Membrane Oxygenation: Insights From Serial Echocardiography.

Extracorporeal membrane oxygenation (ECMO) is often used in acute respiratory distress syndrome (ARDS) with refractory hypoxemia. There is limited literature highlighting the development of right ventricular (RV) failure while on ECMO. We conducted a retrospective multicenter observational study including 70 patients who were placed on veno-venous (VV)-ECMO for respiratory failure at Mayo Clinic, Jacksonville, and Mayo Clinic, Rochester, between January 2018 and June 2022 and had at least two post-ECMO transthoracic echoes.

Association between Impella device support and elevated rates of gout flares: a retrospective propensity-matched study.

Background: Impella is an advanced ventricular assist device frequently used as a bridge to heart transplantation. The association of Impella with increased rates of gout flares has not been studied. Our primary aim is to determine the rates of gout flares in patients on Impella support.

From numbers to medical knowledge: harnessing combinatorial data patterns to predict COVID-19 resource needs and distinguish patient subsets.

Background: The COVID-19 pandemic intensified the use of scarce resources, including extracorporeal membrane oxygenation (ECMO) and mechanical ventilation (MV). The combinatorial features of the immune system may be considered to estimate such needs and facilitate continuous open-ended knowledge discovery.

Materials And Methods: Computer-generated distinct data patterns derived from 283 white blood cell counts collected within five days after hospitalization from 97 COVID-19 patients were used to predict patient's use of hospital resources.

The Effect of Molecular Adsorbent Recirculating System in Patients With Liver Failure: A Case Series of 44 Patients.

Background: Liver failure is associated with a high mortality rate, with many patients requiring transplant for definitive treatment. The Molecular Adsorbent Recirculating System (MARS) is a nonbiologic system that provides extracorporeal support. Literature on MARS therapy is mixed: outcomes support MARS therapy for patients with isolated acute liver failure, but data on patients with chronic disease is varied.

Curcumin-Encapsulated Nanomicelles Promote Tissue Regeneration in Zebrafish Eleutheroembryo.

Regenerative medicine is an emerging field of research aiming to understand the wound healing mechanisms and to develop new therapeutic strategies. Nanocarriers are used to improve drug bioavailability, solubility, and therapeutic abilities. In this study, we used for the first time curcumin loaded oligo kappa-carrageenan-graft-polycaprolactone (oligoKC-g-PCL) nanomicelles to investigate their regenerative potential using a model of tail amputation in zebrafish eleutheroembryo.

Distribution of microglia/immune cells in the brain of adult zebrafish in homeostatic and regenerative conditions: Focus on oxidative stress during brain repair.

Microglia are macrophage-like cells exerting determinant roles in neuroinflammatory and oxidative stress processes during brain regeneration. We used zebrafish as a model of brain plasticity and repair. First, by performing L-plastin (Lcp1) immunohistochemistry and using transgenic Tg(mpeg1.

ApoA-I Nanoparticles as Curcumin Carriers for Cerebral Endothelial Cells: Improved Cytoprotective Effects against Methylglyoxal.

Methylglyoxal (MGO) is a highly reactive metabolite of glucose present at elevated levels in diabetic patients. Its cytotoxicity is associated with endothelial dysfunction, which plays a role in cardiovascular and cerebrovascular complications. Although curcumin has many therapeutic benefits, these are limited due to its low bioavailability.

Charcot Neuroarthropathy Advances: Understanding Pathogenesis and Medical and Surgical Management.

Understanding new theories of the epidemiology of Charcot neuroarthropathy is practice changing. Treatment of Charcot neuroarthropathy is evolving from a passive approach to one that sees the urgency of proactive, early recognition, thereby avoiding the cascading events that lead to the complex, limb-threatening deformities. Preventive medicine is the most efficient at avoiding severe deformity, with prolonged offloading and immobilization as the current mainstay of treatment.

Expression of adiponectin receptors in the brain of adult zebrafish and mouse: Links with neurogenic niches and brain repair.

Adiponectin and its receptors (adipor) have been initially characterized for their role in lipid and glucose metabolism. More recently, adiponectin signaling was shown to display anti-inflammatory effects and to participate in brain homeostasis and neuroprotection. In this study, we investigated adipor gene expression and its regulation under inflammatory conditions in two complementary models: mouse and zebrafish.

Resveratrol attenuates monocyte-to-macrophage differentiation and associated inflammation via modulation of intracellular GSH homeostasis: Relevance in atherosclerosis.

Monocyte-to-macrophage differentiation promotes an inflammatory environment within the arterial vessel wall that causes a mal-adaptive immune response, which contributes to the progression of atheromatous plaque formation. In the current study, we show that resveratrol, a well-known antioxidant, dose-dependently attenuated phorbol myristate acetate (PMA)-induced monocyte-to-macrophage differentiation, as measured by cell adhesion, increase in cell size, and scavenger receptor expression in THP-1 monocytes. Also, resveratrol significantly inhibited PMA-induced pro-inflammatory cytokine/chemokine and matrix metalloprotease (MMP-9) production.
