Can the effects of gender, menopause and ageing on lipid levels be differentiated?
2016
The menopause, as well as ageing in both genders, can influence cardiovascular disease (CVD) risk1. An atherogenic lipoprotein profile, including small dense low density lipoprotein (sdLDL) particles, can be present even in normolipidaemic healthy young individuals (about 6%)2. If confirmed by larger studies, it will be necessary to consider different risk stratifications for those with atherogenic normolipidaemia and those with non-atherogenic hypercholesterolaemia. Furthermore, other changes associated with the menopause (increase in lipoprotein (a) [Lp(a)] levels, central obesity, endothelial dysfunction and systemic inflammation) may contribute to pro-atherogenic changes, while ethnicit…
The value of neutrophil and lymphocyte count in frail older women.
2013
Increasing evidence suggests that systemic inflammation is associated with many pathophysiological processes including frailty in older adults. We evaluated the relationships between white blood cell subtypes, geriatric assessment, and frailty syndrome and in particular, how they correlate with individual frailty criteria (involuntary loss of weight, low energy or exhaustion, slow mobility, muscle weakness, and low physical activity) in frail older women. There was a significant and positive correlation between the frailty score and neutrophil count, but a significantly negative correlation was found when this score was compared to the lymphocyte count. These associations were significant o…

Systemic Inflammation in Metabolic Syndrome: Increased Platelet and Leukocyte Activation, and Key Role of CX3CL1/CX3CR1 and CCL2/CCR2 Axes in Arteria…
2019
Background: Metabolic syndrome is associated with low-grade systemic inflammation, which is a key driver of premature atherosclerosis. We characterized immune cell behavior in metabolic syndrome, its consequences, and the potential involvement of the CX3CL1/CX3CR1 and CCL2/CCR2 chemokine axes. Methods: Whole blood from 18 patients with metabolic syndrome and 21 age-matched controls was analyzed by flow cytometry to determine the leukocyte immunophenotypes, activation, platelet-leukocyte aggregates, and CX3CR1 expression. ELISA determined the plasma marker levels. Platelet-leukocyte aggregates adhesion to tumor necrosis factor-&alpha
Primary hypercholesterolemia and development of cardiovascular disorders: Cellular and molecular mechanisms involved in low-grade systemic inflammati…
2021
Primary hypercholesterolemia, a metabolic disorder characterized by elevated circulating levels of cholesterol products, mainly low-density lipoproteins, is associated with arteriosclerosis development. Cardiovascular disease, predominantly myocardial infarction and stroke, remains the main cause of death worldwide, with atherosclerosis considered to be the most common underlying pathology. In addition to elevated plasma levels of low-density lipoproteins, low-grade systemic inflammation and endothelial dysfunction seem to be the main drivers of premature atherosclerosis. Here we review current knowledge related to cellular and molecular mechanisms involved in low-grade systemic inflammatio…
Polyamines and microbiota in bicuspid and tricuspid aortic valve aortopathy
2019
Polyamines are small aliphatic cationic molecules synthesized via a highly regulated pathway and involved in general molecular and cellular phenomena. Both mammalian cells and microorganisms synthesize polyamines, and both sources may contribute to the presence of polyamines in the circulation. The dominant location for microorganisms within the body is the gut. Accordingly, the gut microbiota probably synthesizes most of the polyamines in the circulation in addition to those produced by the mammalian host cells. Polyamines are mandatory for cellular growth and proliferation. Established evidence suggests that the polyamine spermidine prolongs lifespan and improves cardiovascular health in …
Biomarkers in heart failure
2009
Nowadays, heart failure (HF) has an increasing prevalence, particularly in the elderly, and is becoming a clinical problem of epidemic proportion in terms of morbidity and mortality. Developing biological markers, that can aid in the diagnosis of HF and in the differentiation of congestive heart failure (CHF) from other causes of dyspnoea, will reduce the cost of health care. However, an ideal biomarker has not yet been identified. Potential markers of HF include neuro-hormonal mediators, markers of myocyte injury, and indicators of systemic inflammation. Among these, the BNP and NT-pro-BNP are the most widely studied and appear to be useful in patients with dyspnoea of unknown aetiology, a…
Ability of salivary biomarkers in the prognostic of systemic and buccal inflammation
2017
Nowadays, there is a growing interest in using saliva as an alternative sample for the diagnosis, prediction and progression of several diseases. It has been established that some molecules found in saliva are related to oral inflammatory processes and systemic health status. Furthermore, it is known that saliva is crucial for the carrying out of different functions in the oral cavity and its role in the local modulation of inflammatory and immune response is being thoroughly studied by the health research community. The aim of this review is to analyze the most important biomarkers which have been utilized in biomedicine during the last two decades in order to establish a correlation betwe…
The Obesity Paradox Predicts the Second Wave of COVID-19 to Be Severe in Western Countries.
2021
While COVID-19 infection and mortality rates are soaring in Western countries, Southeast Asian countries have successfully avoided the second wave of the SARS-CoV-2 pandemic despite high population density. We provide a biochemical hypothesis for the connection between low COVID-19 incidence, mortality rates, and high visceral adiposity in Southeast Asian populations. The SARS-CoV-2 virus uses angiotensin-converting enzyme 2 (ACE2) as a gateway into the human body. Although the highest expression levels of ACE2 are found in people’s visceral adipose tissue in Southeast Asia, this does not necessarily make them vulnerable to COVID-19. Hypothetically, high levels of visceral adiposity cause s…
Associations of physical activity, sedentary time, and diet quality with biomarkers of inflammation in children
2022
We investigated the associations of physical activity (PA), sedentary time (ST), and diet quality with biomarkers of inflammation in 390 children (192 girls, 198 boys) aged 6–8 years. PA energy expenditure (PAEE), light PA, moderate PA (MPA), vigorous PA (VPA), moderate-to-vigorous PA (MVPA), and ST were assessed by combined movement and heart rate sensor. Finnish Children Healthy Eating Index was calculated using data from 4 d food records. Body fat percentage (BF%) was measured by dual-energy X-ray absorptiometry. High-sensitivity C-reactive protein (Hs-CRP), leptin, interleukin-6 (IL-6), adiponectin, tumour necrosis factor-α, and glycoprotein acetyls were measured from fasting blood samp…
