Polycystic Ovary Syndrome (PCOS) is associated with a chronic low-grade inflammation and predisposition to hemostatic and atherosclerotic complications. This case-control study evaluated the microparticles (MPs) profile in patients with the PCOS and related these MPs to clinical and biochemical parameters. MPs derived from platelets (PMPs), leuckocytes (LMPs) and endothelial cells (EMPs) were evaluated, as well as MPs expressing tissue factor (TFMPs), by flow cytometry, comparing women with PCOS (n = 50) and a healthy control group (n = 50)...

BACKGROUND: To prevent onset of age-related diseases and physical and cognitive decline, interventions to slow human aging and extend health span must eventually be applied to people while they are still young and healthy. Yet most human aging research examines older adults, many with chronic disease, and little is known about aging in healthy young humans. METHOD: This article explains how this knowledge gap is a barrier to extending health span and puts forward the case that geroscience should invest in researching the pace of aging in young adults...

The prognosis of the antineutrophil cytoplasmic antibody associated vasculitides (AAV), microscopic polyangiitis (MPA), granulomatosis with polyangiitis (GPA) and eosinophilic GPA (EGPA), has been fundamentally improved over the last five decades by the use of glucocorticoids and immunosuppressants, turning them from consistently fatal diseases into chronic conditions. The long-term course is now largely determined by the frequency of disease flares and by accruing damage caused by disease activity and treatment-related comorbidities...

BACKGROUND: The relationship between non-fasting remnant cholesterol and cardiovascular outcome in the era of potent statin therapy remained to be elucidated. METHODS: A cohort study of three hundred and twenty eight diabetics diagnosed with new-onset stable coronary artery disease (CAD) by coronary angiography were enrolled. All cases were followed up for an average duration of twelve months. The association between baseline remnant cholesterol levels and major cardiovascular outcomes were evaluated using the receivers operating characteristic (ROC) curves and Cox proportional hazards regression analysis...

BACKGROUND: HDL function may be more important than HDL concentration in determining risk for cardiovascular disease. In addition, HDL is a carrier of carotenoids and antioxidant enzymes, which protect HDL and LDL particles against oxidation. OBJECTIVE: The goal of this study was to determine the impact of consuming 0-3 eggs/d on LDL and HDL particle size, HDL function, and plasma antioxidants in a young, healthy population. METHODS: Thirty-eight healthy men and women [age 18-30 y, body mass index (in kg/m(2)) 18...

The American Thoracic Society has previously published statements on what constitutes an adverse effect on health of air pollution in 1985 and 2000. We set out to update and broaden these past statements that focused primarily on effects on the respiratory system. Since then, many studies have documented effects of air pollution on other organ systems, such as on the cardiovascular and central nervous systems. In addition, many new biomarkers of effects have been developed and applied in air pollution studies...

BACKGROUND: Studies evaluating the relationship between soluble transferrin receptor (sTfR), a biomarker inversely related to body iron stores, and risk of type 2 diabetes mellitus (T2DM) are scarce and inconclusive. Furthermore, sTfR concentrations have been observed to be significantly higher in obese than in non-obese individuals. Therefore, the aim of the present study was to assess the relationship between sTfR and the risk of T2DM in obese and non-obese subjects. DESIGN: A nested case-control study of 153 cases of newly diagnosed diabetic subjects, 73 obese and 80 non-obese, and 306 individually matched-controls, 138 obese and 166 non-obese, who did not develop T2DM for a median 6-year follow-up (interquartile range: 3...

This prospective study included 152 elderly patients (mean age, 80 years; range, 72-88 years) with a hip fracture treated surgically. Comorbidities were evaluated, and B-type natriuretic peptide was measured at baseline and at postoperative days 4 and 5 in addition to troponin I. Major cardiac events were recorded, and 1-year mortality was assessed. Comorbidity models with the important multivariate predictors of 1-year mortality were analyzed. Overall, 9 patients (6%) experienced major cardiac events postoperatively during their hospitalization...

Dysregulated expression of lysosomal cysteine cathepsins is associated with adverse cardiac remodeling, a characteristic of several cardiovascular diseases. However, the information regarding the role of cysteine cathepsin L (CTSL) and cathepsin B (CTSB) in dilated cardiomyopathy (DCM) is limited. The present study was aimed to investigate the expression of CTSL and CTSB in animal model of doxorubicin (doxo)-induced cardiomyopathy as well as in peripheral blood samples of DCM patients. Cardiac tissue sections from doxo-treated and control rats were used to study the expression of CTSL and CTSB by enzyme assay and immunohistochemistry (IHC)...

It has been suggested that there is an ongoing subclinical inflammation in familial Mediterranean fever (FMF) patients also in attack-free periods as well. Due to this ongoing inflammation, endothelial dysfunction (ED) may develop. Previously, ED has been suggested to increase the risk of the atherosclerosis and cardiovascular disease (CVD). Endocan is recognized as a specific molecule of the endothelium and has been shown to increase in some cases associated with inflammation. However, there is not sufficient data whether those with FMF could develop ED in the early period of life...

BACKGROUND: Identifying novel risk markers in cardiovascular patients remains a research priority. Longer follow-up generally is considered favorable in such studies, but associations of interest may become attenuated with increasing follow-up. This issue has not been adequately addressed in the context of patient cohorts. The current study analyzed the extent and mechanisms of attenuating associations in a cardiovascular patient cohort. METHODS: The associations of numerous biomarkers with all-cause mortality were estimated by multiple Cox regression in the Langzeiterfolge der KARdiOLogischen Anschlussheilbehandlung (KAROLA) prospective cohort study of 1204 patients who had participated in an inpatient rehabilitation program after an acute coronary syndrome (ACS) or coronary bypass operation...

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) have increased cardiovascular risk. Natriuretic peptides (NP) in other populations are useful in identifying cardiovascular disease, stratifying risk, and guiding therapy. METHODS: We performed a systematic literature review to examine NP in COPD, utilising Medline, EMBASE, and the Cochrane Library. RESULTS: Fifty one studies were identified. NP levels were lower in stable compared to exacerbation of COPD, and significantly increased with concomitant left ventricular systolic dysfunction or cor pulmonale...

Recent studies have shown platelet to lymphocyte ratio (PLR) to be a potential inflammatory marker in cardiovascular diseases. We performed a meta-analysis to systematically evaluate the prognostic role of PLR in acute coronary syndrome (ACS). A comprehensive literature search up to May 18, 2016 was conducted from PUBMED, EMBASE and Web of science to identify related studies. The risk ratio (RR) with 95% confidence interval (CI) was extracted or calculated for effect estimates. Totally ten studies involving 8932 patients diagnosed with ACS were included in our research...

Aortic dissection (AD), a severe cardiovascular disease with the characteristics of high mortality, is lack of specific clinical biomarkers. In order to facilitate the diagnosis of AD, we investigated plasma amino acid profile through metabolomics approach. Total 33 human subjects were enrolled in the study: 11 coronary heart disease (CHD) patients without aortic lesion and 11 acute AD and 11 chronic AD. Amino acids were identified in plasma using liquid chromatography and mass spectrometry (LC-MS/MS), and were further subjected to multiple logistic regression analysis...

BACKGROUND: Magnesium (Mg) and calcium (Ca) are the principal essential elements involved in endothelial cell homeostasis. Extracellular changes in the levels of either alter endothelial contraction and dilatation. Consequently Mg and Ca imbalance is associated with a high risk of endothelial dysfunction, the main process observed during acute aortic dissection (AAD); in this clinical condition, which mainly affects elderly men, smooth muscle cell alterations lead to intimal tears, creating a false new lumen in the media of the aorta...

PURPOSE: Exposure of the general population to ionizing radiation has increased in the past decades, primarily due to long distance travel and medical procedures. On the other hand, accidental exposures, nuclear accidents, and elevated threats of terrorism with the potential detonation of a radiological dispersal device or improvised nuclear device in a major city, all have led to increased needs for rapid biodosimetry and assessment of exposure to different radiation qualities and scenarios...

Heart failure (HF) is a widely prevalent syndrome imposing a significant burden of morbidity and mortality world-wide. Differential circulating microRNA profiles observed in HF cohorts suggest the diagnostic utility of microRNAs as biomarkers. Given their function in fine tuning gene expression, alternations in microRNA landscape could reflecting the underlying mechanisms of disease and present potential therapeutic targets. Using multiple computational target predicting algorithms together with the luciferase-based reporting platform, the interactions between HF-related microRNAs and the 3' untranslated regions (3'UTRs) of neurohormone associated genes were examined and compared...

Ischemia/reperfusion injury adversely affects the final infarct size (IS) after primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI). Few studies have evaluated the role of remote ischemic conditioning (RIC) in reducing ischemia/reperfusion injury. However, the results of these studies were not consistent, and an overview of overall effectiveness of this technique in patients with STEMI is lacking. We conducted this meta-analysis to evaluate the available evidence in literature regarding the application of RIC in patients with STEMI who underwent primary PCI...
