Tocilizumab-related hypertriglyceridemia is independent of key molecules regulating lipid metabolism.
Tocilizumab (TCZ) treatment is associated with dyslipidaemia, including a rise in triglycerides through a mechanism poorly understood. Three molecules play key roles in the regulation of triglyceride metabolism: apolipoprotein C-III (ApoC-III), angiopoietin-like protein 4(ANGPLT4) and lipoprotein lipase (LPL). The aim of this work was to analyse whether the changes in triglycerides shown by TCZ-treated RA patients could stem from the dysregulation that can occur in these regulatory molecules. ⋯ In TCZ-treated RA patients basal serum levels of ANGPLT4 and ApoC-III, but not LPL, decreased significantly. However, the elevation of triglycerides after TCZ was not related to changes in these regulatory molecules.

Clinical Outcomes and Phylogenetic analysis in Reflection with Three Predominant Clades of SARS-CoV-2 Variants.
The pandemic of coronavirus disease 2019 (COVID-19) has a broad spectrum of clinical manifestations. The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) undergoes continuous evolution, resulting in the emergence of several variants. Each variant has a different severity and mortality rate. ⋯ There has been a surge in COVID-19 infection in the city due to the predominant lineages of SARS-CoV-2, B.1.617, Omicron BA.1.17.2 and Omicron BA.5.6, respectively. A higher PCR-Ct value and severity of the Delta variant over Omicron BA.1.17.2 and/or BA.5.2 variants were significantly correlated with a higher death rate in the same order.

Endovascular Aortic Repair Impact on Myocardial Contractility: A Prospective Study.
This study aimed to estimate if the altered sphygmic wave transmission may affect the left ventricular (LV) contractile function in patients undergoing endovascular aortic repair (EVAR). ⋯ Our data showed that EVAR induced an altered transmission of the sphygmic wave associated with an early LV contractile impairment.

One-hour post-load glucose and subclinical left atrial myocardial dysfunction in hypertensive patients.
Recently, studies demonstrated that normal glucose-tolerant subjects (NGT) with 1-h post-load plasma glucose value ≥155 mg/dL during oral glucose tolerance test (OGTT) (NGT ≥ 155) present an impaired cardio-metabolic profile, with subclinical myocardial damage. Atrial morphological and functional alterations, closely related to diastolic dysfunction, are important predictors of atrial fibrillation (AF), cardiovascular (CV) events and mortality in the entire population as well as in diabetic patients. The aim of our study was to evaluate subclinical atrial myocardial damage, assessed with speckle tracking echocardiography, in NGT≥155 mg/dL patients, comparing to NGT < 155 mg/dL subjects, impaired glucose tolerant (IGT) individuals and patients with newly diagnosed type 2 diabetes (T2DM). ⋯ Present data demonstrated for the first time that NGT≥155 subjects present subclinical atrial dysfunction. These results may be clinically relevant because they highlight how atrial myopathy occurs early in pre-diabetes stage regardless of fibrotic and morphological alterations of the ventricular myocardium.

Elevated factor XIa as a modulator of plasma fibrin clot properties in coronary artery disease.
Patients with coronary artery disease (CAD) display a prothrombotic fibrin clot phenotype, involving low permeability and resistance to lysis. The determinants of this phenotype remain elusive. Circulating tissue factor (TF) and activated factor XI (FXIa) are linked to arterial thromboembolism. We investigated whether detectable active TF and FXIa influence fibrin clot properties in CAD. ⋯ To our knowledge, this study is the first to show that circulating FXIa is associated with prothrombotic fibrin clot properties in CAD, suggesting additional mechanisms through which FXIa inhibitors could act as novel antithrombotic agents in CAD.
