Controlling hypersonic surface acoustic waves is crucial for advanced phononic devices such as high-frequency filters, sensors, and quantum computing components. While periodic phononic crystals enable precise bandgap engineering, their ability to suppress acoustic waves is limited to specific frequency ranges. Here, we experimentally demonstrate surface acoustic wave control using a hyperuniform arrangement of gold nanopillars on a lithium niobate layer.

Hypertension and hypercholesterolemia often occur in the same individuals, increasing the risk of major cardiovascular (CV) outcomes, including myocardial infarction, stroke, CV death, as well as other CV complications. Concomitant management of these condition now represent a crucial step to reduce individual global CV risk and improve CV disease prevention in daily clinical practice. Given the high prevalence of hypertension and hypercholesterolemia in general population and their impact on health status, several pharmacological options are currently available to achieve the recommended therapeutic targets.

Article Synopsis
  • Secondary bacterial infections (SBIs) are linked to worse hospital outcomes for COVID-19 patients, with prior treatment using proton pump inhibitors (PPIs) increasing the risk of these infections.
  • In a study of 1,087 hospitalized COVID-19 patients, 41% were on PPIs prior to admission, leading to higher rates of SBIs (18%) and secondary bacterial sepsis (SBS) (20%).
  • PPI treatment was associated with a significantly greater risk of developing SBIs and SBS, which in turn increased the likelihood of ICU admissions or in-hospital deaths, highlighting the need for cautious PPI use in these patients.

Phonon engineering at the nanoscale holds immense promise for a myriad of applications. However, the design of phononic devices continues to rely on regular shapes chosen according to long-established simple rules. Here, we demonstrate an inverse design approach to create a two-dimensional phononic metasurface exhibiting a highly anisotropic phonon dispersion along the main axes of the Brillouin zone.

Echolucency, a measure of plaque instability associated with increased cardiovascular risk, can be assessed in both the carotid plaque and the plaque-free common carotid intima-media (IM) complex as a gray-scale median (plaque-GSM and IM-GSM, respectively). The impact of specific vascular risk factors on these two phenotypes remains uncertain, including the nature and extent of their influence. This study aims to seek the determinants of plaque-GSM and IM-GSM.

Atherosclerotic cardiovascular diseases remain the main cause of mortality worldwide, due to a poor control of modifiable risk factors for atherosclerosis. High levels of low-density lipoprotein cholesterol represent the most relevant actor in the development of atherosclerotic cardiovascular diseases, as well as the main target of prevention strategies. Although lipid-lowering treatments were shown to be effective for cardiovascular prevention, several barriers (e.

The prothrombotic and proinflammatory properties of lipoprotein(a) (Lp(a)) have been hypothesized to play a role in the pathogenesis of severe COVID-19; however, the prognostic impact of Lp(a) on the clinical course of COVID-19 remains controversial. This study aimed to investigate whether Lp(a) may be associated with biomarkers of thrombo-inflammation and the occurrence of thrombotic events or adverse clinical outcomes in patients hospitalized for COVID-19. We consecutively enrolled a cohort of patients hospitalized for COVID-19 and collected blood samples for Lp(a) assessment at hospital admission.

Introduction: Atherosclerotic cardiovascular disease (ASCVD) is the main cause of morbidity and mortality worldwide. Dyslipidemia, in particular elevation of LDL-cholesterol levels (LDL-C), is one of the major cardiovascular risk factors and is characterized by high prevalence and independent unfavorable impact on cardiovascular prognosis; however, because of its asymptomatic course, it often remains undiagnosed. Strategies aimed at early identification of subjects with elevated LDL-C levels may allow early intervention, preventing ASCVD development.

Current cardiovascular disease prevention strategies are based on the management of cardiovascular risk as a continuum, redefining the therapeutic goals for each individual based on the estimated global risk profile. Given the frequent clustering of the principal cardiovascular risk factors, such as hypertension, diabetes and dyslipidaemia, in the same individual, patients are required to take multiple drugs to achieve therapeutic targets. The adoption of single pill fixed dose combinations may contribute to achieve better control of blood pressure and cholesterol compared to the separate administration of the individual drugs, mostly due to better adherence related to therapeutic simplicities.

Statins may protect against adverse outcomes from Coronavirus disease 2019 (COVID-19) through their pleiotropic effects. Endothelial dysfunction seems to be implicated in the pathophysiology of COVID-19, and can be attenuated by statins. This study assessed the role of preadmission statin therapy and its interaction with endothelial function, measured using flow-mediated dilation (FMD) at hospital admission, in predicting in-hospital outcomes among patients with COVID-19 having high-to-very high cardiovascular (CV) risk.

Cardiovascular disease (CVD) is a chronic non-communicable disease (NCD) and the predominant cause of morbidity and mortality worldwide. Substantial reductions in the CVD prevalence have been achieved in recent years by the attenuation of risk factors (particularly hypertension and dyslipidaemias) in primary and secondary prevention. Despite the remarkable success of lipid lowering treatments, and of statins in particular, in reducing the risk of CVD, there is still an unmet clinical need for the attainment of guideline lipid-targets in even 2/3 of patients.
