Cardiovascular disease (CVD) remains a leading cause of morbidity and mortality worldwide with 20 million deaths annually. Recent advances in both primary and secondary prevention strategies have shown promising results in reducing the incidence and recurrence of cardiovascular events, but a question of fundamental importance is whether we are effective enough when predicting risk only in those over 40 years of age and only for 10 years. A similarly important question concerns the pathophysiological border between primary and secondary prevention and whether we should reorient our focus to atherosclerosis prevention as a continuous process that becomes clinically apparent later in life.

Introduction: Classical risk factors such as hypertension, hypercholesterolemia, pre-diabetes, diabetes and obesity can predict adverse cardiovascular events, but they are less prognostic in patients aged < 60 years. Polygenic risk scores (PRS) can be effective in predicting adverse coronary events in younger and middle-aged patients. Our main aim is to assess the utility of a new PRS created for the Polish population in predicting mortality during an 8-year follow-up in the nationwide LIPIDOGEN2015 population.

Article Synopsis
  • Despite the availability of lipoprotein-lowering medications, some high-risk patients with persistent high cholesterol may need alternative treatments like lipoprotein apheresis (LA).
  • LA is particularly beneficial for individuals with familial hypercholesterolemia and not only lowers cholesterol but also improves heart function and reduces inflammation.
  • While studies show LA leads to better cardiovascular outcomes, its use in the U.S. is limited, and more research is needed on its benefits for certain kidney conditions.

Aging is closely associated with various cerebrovascular pathologies that significantly impact brain function, with cerebral small vessel disease (CSVD) being a major contributor to cognitive decline in the elderly. Consequences of CSVD include cerebral microhemorrhages (CMH), which are small intracerebral bleeds resulting from the rupture of microvessels. CMHs are prevalent in aging populations, affecting approximately 50% of individuals over 80, and are linked to increased risks of vascular cognitive impairment and dementia (VCID).

Article Synopsis
  • A new potential energy surface (PES) has been created for the Cl + CH3CN chemical reaction, building on previous research that accurately identified stationary points of the reaction.
  • The PES is achieved using advanced fitting methods, and simulations at various collision energies reveal several low-probability reaction pathways, with H-abstraction being the most significant.
  • As collision energy increases, the reaction dynamics shift from indirect/rebound mechanisms to direct stripping, with the products showing various energy distributions—HCl mainly in the ground vibrational state and CH2CN with notable vibrational excitation.

Introduction: Despite decades of research clearly illustrating the direct link between low-density lipoprotein cholesterol (LDL-C) and atherosclerotic cardiovascular disease (ASCVD) risk, LDL-C goal attainment rates are remarkably low in both the primary and secondary prevention settings.

Areas Covered: Herein we detail: (1) the low rates of LDL-C goal attainment; (2) despite guidelines clearly outlining indications of use, there is suboptimal initiation, intensification, and persistence of lipid lowering therapy, especially combination therapy; (3) key clinician-related factors contributing to this gap include inconsistent risk assessments, clinical inertia, and barriers to health access; (4) LDL-C reduction is associated with reductions in risk for cardiovascular events. Increasing LDL-C goal attainment rates should be a high public health priority.

The association of thyroid function with essential and non-essential amino acids is understudied, despite their common metabolic roles. Thus, our aim was to evaluate the association of thyroid function with the levels of branched-chain amino acids (BCAAs-leucine, isoleucine, and valine) and of alanine in the general population. We utilized data from the São Paulo research center of ELSA-Brasil, a longitudinal population-based cohort study.

  • The study investigates the effectiveness of high-power short-duration (90 W/4 s) radiofrequency ablation for pulmonary vein isolation (PVI) in patients with atrial fibrillation, particularly looking at gaps in ablation lines that can lead to recurrences.
  • Using data from 20 patients and analyzing 1,357 ablation points, the researchers identified key factors affecting the occurrence of these gaps, including interlesion distance (ILD) and generator impedance.
  • The findings suggest that smaller ILDs (3.5 mm anteriorly and 4 mm posteriorly) improve the durability of PVI, indicating that adjustments in ablation techniques might be necessary compared to traditional approaches.

On average, LDL particles are the most populous lipoprotein in serum under fasting conditions. For many reasons, it has been the primary target of lipid-lowering guidelines around the world. In the past 30 years, we have witnessed remarkable changes in each iteration of dyslipidaemia guidelines, with LDL-cholesterol (LDL-C) targets becoming lower and lower among patients at high and very high risk for atherosclerotic cardiovascular disease (ASCVD).

Consensus holds that pottery technology came to Central Europe from the Northern Balkans with independent pottery traditions existing concurrently in Eastern Europe. An unusual grass-tempered pottery dating back to around 5800 cal BC found in lake sediments at Santovka, Slovakia, predated the earliest known Neolithic pottery in the region (~ 5500 cal BC), suggesting unexplored narratives of pottery introduction. Analyses of the pottery's technology, origin, and grass temper shedding light on ceramic traditions' spread can unveil mobility patterns and community lifestyles.

Cerebral microhemorrhages (CMHs) are of paramount importance as they not only signify underlying vascular pathology but also have profound implications for cognitive function and neurological health, serving as a critical indicator for the early detection and management of vascular cognitive impairment (VCI). This study aimed to investigate the effects of hypertension-induced CMHs on gait dynamics in a mouse model, focusing on the utility of advanced gait metrics as sensitive indicators of subclinical neurological alterations associated with CMHs. To induce CMHs, we employed a hypertensive mouse model, using a combination of Angiotensin II and L-NAME to elevate blood pressure, further supplemented with phenylephrine to mimic transient blood pressure fluctuations.

Phospholipids (PLs) are asymmetrically distributed at the plasma membrane. This asymmetric lipid distribution is transiently altered during calcium-regulated exocytosis, but the impact of this transient remodeling on presynaptic function is currently unknown. As phospholipid scramblase 1 (PLSCR1) randomizes PL distribution between the two leaflets of the plasma membrane in response to calcium activation, we set out to determine its role in neurotransmission.

Aging plays a pivotal role in the pathogenesis of cerebral small vessel disease (CSVD), contributing to the onset and progression of vascular cognitive impairment and dementia (VCID). In older adults, CSVD often leads to significant pathological outcomes, including blood-brain barrier (BBB) disruption, which in turn triggers neuroinflammation and white matter damage. This damage is frequently observed as white matter hyperintensities (WMHs) in neuroimaging studies.

Article Synopsis
  • The interaction between endothelial cells (ECs) and the matrix is crucial for controlling nuclear tension, which helps prevent gene synthesis errors and the transition to a "leaky" state associated with acute lung injury (ALI).
  • Focal adhesion kinase (FAK) plays a key role in this process by maintaining the transmission of tension to the nucleus, ensuring that ECs remain in a restrictive state.
  • When FAK is depleted, activation of the RhoA-Rho-kinase pathway leads to increased tension and phosphorylation of nuclear proteins, resulting in the downregulation of important genes like KLF2, contributing to the leaky EC state; restoring FAK can reverse this process and maintain lung health.
