Mortality associated with cardiovascular disease in patients with COVID-19
2020
Introducción y objetivos: Las enfermedades cardiovasculares (ECV) se han identificado como un factor de riesgo de mal pronóstico en pacientes con infección por COVID-19. Métodos: Se realizó un metanálisis de estudios actualmente disponibles con la prevalencia de ECV en supervivientes frente a no supervivientes en pacientes con infección por COVID-19 hasta el 16 de julio de 2020. Los análisis se realizaron mediante un modelo de efectos aleatorios y sensibilidad. Se realizaron análisis para identificar posibles fuentes de heterogeneidad o evaluar los efectos de los estudios pequeños. Resultados: Se incluyó a 307.596 pacientes de 16 estudios, de los que 46.321 (15,1%) tenían ECV. La tasa de mo…
Atherosclerosis: risk assessment and the role of aiming for optimal glycaemic control in young patients with type 1 diabetes
2023
Wprowadzenie: Dzieci z cukrzycą typu 1 (type 1 diabetes mellitus – DM1) mają w porównaniu ze zdrowymi rówieśnikami podwyższone ryzyko rozwoju zaawansowanej miażdżycy oraz choroby sercowo-naczyniowej (cardiovascular disease – CVD), a niedostateczna kontrola glikemii jest najważniejszym modyfikowalnym czynnikiem ryzyka CVD w DM1. Aktualne metody oceny kontroli glikemii to ocena hemoglobiny glikowanej (HbA1c), samokontrola glikemii za pomocą glukometru (SMBG), a także stosowanie systemów ciągłego monitorowania glukozy (CGM). Do pośredniej oceny ryzyka rozwoju CVD mogą służyć badania rozszerzenia tętnicy w odpowiedzi na niedokrwienie (flow-mediated dilatation – FMD) i prędkości fali tętna (PWV)…
Influence of B content on microstructure, phase composition and mechanical properties of CVD Ti(B,N) coatings
2022
Within this work the effect of the B content on the microstructure, phase composition and mechanical properties of CVD Ti(B,N) coatings is investigated. Ti(B,N) coatings with B contents from 0 (fcc-TiN) to ∼5, ∼15, ∼30, ∼45 and 66 (h-TiB2) at.% have been deposited by CVD. The elemental composition of the coatings was confirmed by ERDA and their microstructure was investigated using XRD and SEM. With increasing B content, a transition from a fcc to a h-dominated structure via dual-phase fcc/h-Ti(B,N) was observed, which was accompanied by a decreasing grain size from the µm to nm range. Combinatorial use of Raman spectroscopy, XPS and APT measurements indicated B-rich grain boundary segregat…
Red Blood Cells Distribution Width as Biomarker of Worsening in Atherosclerosis
2018
Red blood cell Distribution Width (RDW) is a parameter of the circulating erythrocytes’ size that it has reported to be associated with Cardiovascular Diseases (CVDs) [1-7]. The related mechanism of this association is not fully understood. However, RDW is an indicator of inflammation related to early inflammatory biomarkers, such as C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) [8,9]. Accordingly, systemic chronic inflammation leads to dysfunctional bone marrow with unsuccessful production of red blood cells [10]. As a result, it determines the migration of reticulocytes into the peripheral circulation, followed by an increase in circulating levels of i…
Atherosclerosis Development and Progression: The Role of Atherogenic Small, Dense LDL.
2022
Atherosclerosis is responsible for large cardiovascular mortality in many countries globally. It has been shown over the last decades that the reduction of atherosclerotic progression is a critical factor for preventing future cardiovascular events. Low-density lipoproteins (LDL) have been successfully targeted, and their reduction is one of the key preventing measures in patients with atherosclerotic disease. LDL particles are pivotal for the formation and progression of atherosclerotic plaques; yet, they are quite heterogeneous, and smaller, denser LDL species are the most atherogenic. These particles have greater arterial entry and retention, higher susceptibility to oxidation, as well a…
