Percutaneous Microaxial Ventricular Assist Device Versus Intra-Aortic Balloon Pump for Nonacute Myocardial Infarction Cardiogenic Shock.

Background: Evidence on the comparative outcomes following percutaneous microaxial ventricular assist devices (pVAD) versus intra-aortic balloon pump for nonacute myocardial infarction cardiogenic shock is limited.

Methods And Results: We included 704 and 2140 Medicare fee-for-service beneficiaries aged 65 to 99 years treated with pVAD and intra-aortic balloon pump, respectively, for nonacute myocardial infarction cardiogenic shock from 2016 to 2020. Patients treated using pVAD compared with those treated using intra-aortic balloon pump were more likely to be concurrently treated with mechanical ventilation, renal replacement therapy, and blood transfusions.

Renal replacement therapy prior to liver transplant and inpatient mortality in patients without advanced kidney disease: A nationwide study.

Background And Aim: The utility of renal replacement therapy (RRT) before liver transplant (LT) in patients without end-stage renal disease (ESRD) or advanced chronic kidney disease (CKD-IV/V) is debatable and lacks data support. We aimed to evaluate the impact of RRT on patients undergoing LT.

Methods: We used the National Readmission Database (2016-2019) to identify all index hospitalizations undergoing RRT before LT (cases).

Transcatheter Aortic Valve Replacement in Patients With or Without Active Cancer.

Background Data on clinical outcomes after transcatheter aortic valve replacement (TAVR) in specific cancer types or the presence of metastatic disease remain sparse. This study aimed to investigate the impact of active cancer on short-term mortality, complications, and readmission rates after TAVR across different cancer types.

Risk Stratification Tools to Guide a Personalized Approach for Cardiac Monitoring in Embolic Stroke of Undetermined Source.

Current recommendations support a personalized sequential approach for cardiac rhythm monitoring to detect atrial fibrillation after embolic stroke of undetermined source. Several risk stratification scores have been proposed to predict the likelihood of atrial fibrillation after embolic stroke of undetermined source. This systematic review aimed to provide a comprehensive overview of the field by identifying risk scores proposed for this purpose, assessing their characteristics and the cohorts in which they were developed and validated, and scrutinizing their predictive performance.

Next-generation sequencing of baseline genetic mutations and outcomes of eltrombopag and azacitidine therapy in patients with myelodysplastic syndromes and thrombocytopenia: Data from the SUPPORT clinical trial.

Eltrombopag has been previously shown to be effective in reversing azacitidine-mediated thrombocytopenia. This was further investigated in the SUPPORT trial, a phase III study assessing the efficacy/safety of eltrombopag plus azacitidine in patients with intermediate- to high-risk myelodysplastic syndromes and thrombocytopenia. The results did not support a clinical benefit for the addition of eltrombopag to azacitidine.

Beneficial effects of L-Arginine in patients hospitalized for COVID-19: New insights from a randomized clinical trial.

We have recently demonstrated in a double-blind randomized trial the beneficial effects of L-Arginine in patients hospitalized for COVID-19. We hypothesize that one of the mechanisms underlying the favorable effects of L-Arginine is its action on inflammatory cytokines. To verify our hypothesis, we measured longitudinal plasma levels of pro-inflammatory and anti-inflammatory cytokines implied in the pathophysiology of COVID-19 in patients randomized to receive oral L-Arginine or placebo.

Ross Procedure Versus Mechanical Versus Bioprosthetic Aortic Valve Replacement: A Network Meta-Analysis.

Background The Ross operation appears to restore normal survival in young and middle-aged adults with aortic valve disease. However, there are limited data comparing it with conventional aortic valve replacement. Herein, we compared outcomes of the Ross procedure with mechanical and bioprosthetic aortic valve replacement (M-AVR and B-AVR, respectively).

Bezold-Jarisch reflex mediated syncope in pulmonary arterial hypertension: An illustrative case series.

We present a novel description of Bezold-Jarisch Reflex (BJR) during cardiopulmonary exercise testing (CPET) in three young female patients with Group 1 pulmonary arterial hypertension (PAH). These three cases presented within 26 months, representing only 0.8% of 11,387 tests on patients with PAH undergoing CPET during this time frame.

Objective: To attain a better understanding of the structure and processes of Research Ethics Committees (REC) in the low-and middle-income countries of the Mesoamerican region. The objectives are knowing the operational practices of the RECs regarding project evaluation, training needs, and infrastructure.

Materials And Methods: The REC training and needs assessment involved an online survey of all the RECs (n=55) identified in Colombia (n=11), Costa Rica (n=5), Guatemala (n=5), and Mexico (n=34).

Lamp1 mediates lipid transport, but is dispensable for autophagy in .

The endolysosomal system not only is an integral part of the cellular catabolic machinery that processes and recycles nutrients for synthesis of biomaterials, but also acts as signaling hub to sense and coordinate the energy state of cells with growth and differentiation. Lysosomal dysfunction adversely influences vesicular transport-dependent macromolecular degradation and thus causes serious problems for human health. In mammalian cells, loss of the lysosome associated membrane proteins LAMP1 and LAMP2 strongly affects autophagy and cholesterol trafficking.

Nuances in detecting retained foreign bodies: a case report of a glass shard embedded in a child's scalp.

Foreign bodies (FBs) are a relatively common reason for admission to the emergency department, with subacutely embedded FBs presenting a diagnostic challenge to physicians. Retained FBs may cause the patient harm and result in litigation when missed. Diagnostic imaging is a powerful tool for localization of FBs and a physician's choice of modality should reflect its anticipated composition.

Normative data for the Brief Spanish-English Verbal Learning Test for representative and diverse Hispanics/Latinos: Results from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL).

Introduction: Episodic learning and memory performance are crucial components of cognitive assessment. To meet the needs of a diverse Hispanic/Latino population, we aimed to provide normative data on the Brief Spanish-English Verbal Learning Test (B-SEVLT).

Methods: The target population for the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) included individuals 45+ years old from Central American, Cuban, Dominican, Mexican, Puerto Rican, and South American backgrounds.

Rediscovered and Unforgotten: Transcatheter Interventions for the Treatment of Severe Tricuspid Valve Regurgitation.

Tricuspid valve regurgitation is both globally prevalent and undertreated. Historically, surgical intervention for isolated tricuspid regurgitation (TR) was avoided despite the prevalence of TR, largely due to poor surgical outcomes and an incomplete understanding of how it independently affects mortality. Over the past two decades, TR has been shown by several studies to be an independent predictor of worse functional status and poor survival on long-term follow-up.

Lower hair cortisol among patients with sickle cell disease may indicate decreased adrenal reserves.

Introduction: Sickle cell disease (SCD) is a chronic illness that presents with a wide range of phenotypic variation. Stress may be a contributing factor to differences that are found in this population.

Objectives: Our objective is to determine the relationship between hair cortisol content (HCC), a biomarker of stress, and other clinical measures in individuals with SCD.

Revascularization approaches in patients with radiation-induced carotid stenosis: an updated systematic review and meta-analysis.

Background: Ionizing radiation remains a well-known risk factor of carotid artery stenosis. The survival rates of head and neck cancer patients undergoing radiotherapy have risen owing to medical advancements in the field. As a consequence, the incidence of carotid artery stenosis in these high-risk patients has increased.

Adipokines and Subclinical Cardiovascular Disease in Post-Menopausal Women: Study of Women's Health Across the Nation.

Background The menopausal transition is characterized by increased cardiovascular risk, weight gain, and increased adiposity for many women. The adipose-derived secretory proteins adiponectin and leptin are associated with insulin resistance, metabolic syndrome, and cardiovascular disease but their role in subclinical atherosclerotic disease is unclear. This cross-sectional study evaluated the associations of adiponectin and leptin with carotid artery intima-media thickness, adventitial diameter, presence of carotid plaques, and brachial-ankle pulse wave velocity (baPWV) in women aged 54 to 65 years.

Menopausal Vasomotor Symptoms and Risk of Incident Cardiovascular Disease Events in SWAN.

Background Cardiovascular disease (CVD) in women has unique features, including associations with reproductive factors that are incompletely understood. Vasomotor symptoms (VMS), the classic menopausal symptom, are linked to CVD risk factors and subclinical CVD. Evidence linking VMS to CVD events is limited.
