Size and subclasses of low-density lipoproteins in patients with obstructive sleep apnea.
2012
Patients with obstructive sleep apnea (OSA) have proatherogenic dyslipidemia. We analyzed predictors of low-density lipoproteins' (LDLs) size in patients with OSA. In a cross-sectional study including 58 participants with OSA (30 without the metabolic syndrome [MetS] and 28 with MetS), we evaluated the size of LDL by gradient gel electrophoresis. Compared with patients without the MetS, those with MetS showed lower LDL size ( P = .007), due to a reduction in large LDL-I particles ( P = .002) and an increase in small, dense LDL-IIIA ( P = .048) and LDL-IIIB ( P = .037). The size of LDL correlated inversely with age ( r = −.268, P = .042) and serum triglycerides ( r = −.364, P = .005), and p…
Characteristics of patients with type 2 diabetes mellitus newly treated with GLP-1 receptor agonists (CHADIG Study): a cross-sectional multicentre st…
2016
Ajuda rebuda: GlaxoSmithKline Several glucagon-like peptide-1 (GLP-1) receptor agonists (GLP-1Ra) have been made recently available in Spain for type 2 diabetes mellitus (DM2) treatment. There are no published data on the clinical and sociodemographic profile of patients initiating treatment with GLP-1Ra in Spain. Our objective was to understand these patients' characteristics in a real-world clinical practice setting. Design. Cross-sectional observational study. Setting. Spanish specialist outpatient clinics.Participants 403 adults with DM2 initiating GLP-1Ra treatment were included. Primary and secondary outcome measures Sociodemographic and DM2-related clinical data, including treatment …
A Decision Support Tool for Appropriate Glucose-Lowering Therapy in Patients with Type 2 Diabetes
2015
Contains fulltext : 152084.pdf (Publisher’s version ) (Open Access) BACKGROUND: Optimal glucose-lowering therapy in type 2 diabetes mellitus requires a patient-specific approach. Although a good framework, current guidelines are insufficiently detailed to address the different phenotypes and individual needs of patients seen in daily practice. We developed a patient-specific decision support tool based on a systematic analysis of expert opinion. MATERIALS AND METHODS: Based on the American Diabetes Association (ADA)/European Association for the Study of Diabetes (EASD) 2012 position statement, a panel of 12 European experts rated the appropriateness (RAND/UCLA Appropriateness Method) of tre…

Colesterol-no HDL como objetivo terapéutico
2019
Although cholesterol linked to low-density lipoproteins (c-LDL) is well established as a risk factor for cardiovascular disease, there is often a more complex dyslipidaemia pattern that contributes to the formation of atherosclerotic plaque. Non-HDL cholesterol (c-NO-HDL) is used to estimate the total amount of atherogenic lipoproteins in plasma, some of which are not usually determined in daily clinical practice. c-NO-HDL is easily calculated from the subtraction of total plasma cholesterol from the cholesterol content carried by high density lipoproteins. The c-NO-HDL has a predictive value superior to that of C-LDL to estimate the risk of major cardiovascular events in epidemiological st…
Aromatase and amphiregulin are correspondingly expressed in human liver cancer cells
2009
Human hepatocellular carcinoma (HCC) is associated with high mortality rates, being the third most common cause of cancer death worldwide. Although estrogens have been implicated in HCC, their potential role in development and/or progression of this malignancy remains unclear. In this study we investigated mRNA and protein expression of aromatase (Aro) and amphiregulin (AREG) in relation to estrogen receptors (ERs), in HepG2, Huh7, and HA22T human malignant liver cell lines, using RT-PCR and Western blot analyses. Aro expression was significantly higher (approximately 13-fold, P= 0.003) in HepG2 cells than in Huh7 cells, while no Aro expression could be detected in HA22T cells. Interestingl…
Control of ovarian steroidogenesis in insects: A locust neurohormone is active in vitro on blowfly ovaries
2009
0016-6480 doi: DOI: 10.1016/j.ygcen.2009.04.034; Ovarian steroidogenesis controlling insect reproduction is mainly regulated by brain gonadotropins liberated from corpora cardiaca (CC). Till now, different neurohormones have been identified in two insect groups only, locusts and mosquitoes, and it is unknown whether they could be active in other insects. In order to complete previous observations on the control of ovarian steroidogenesis in the blowfly, Phormia regina, we examined whether neuropeptides isolated from locust CC have an effect in vitro on ovarian steroidogenesis in our dipteran model. Our experiments showed that crude extracts from locust CC efficiently stimulated steroidogene…
Prognostic Value and Kinetics of Soluble Neprilysin in Acute Heart Failure
2015
Abstract Objectives This study sought to examine the prognostic value of the soluble form of neprilysin (sNEP) in acute heart failure (AHF) and sNEP kinetics during hospital admission. Background sNEP was recently identified in chronic heart failure (HF) and was associated with cardiovascular outcomes. Methods A total of 350 patients (53% women, mean 72.6 ± 10.7 years of age) were included in the study. Primary endpoints were composites of cardiovascular death or HF hospitalizations at short-term (2 months) and long-term (mean: 1.8 ± 1.2 years) follow-up. sNEP was measured using an ad hoc–modified enzyme-linked immunosorbent assay, and its prognostic value was assessed using Cox regression …
0283: Correlation between N-terminal pro-natriuretic peptide levels and left atrial size in patients with left ventricular systolic dysfunction
2014
BackgroundElevated N-terminal Pro B-type Natriuretic Peptide (NT Pro-BNP) levels are correlated with the severity of left ventricular systolic dysfunction and left ventricular filling alterations. Besides, left atrial (LA) size is believed to reflect chronic diastolic dysfunction.AimEvaluate the relationship between NT Pro-BNP and LA size.Methods81 patients (77.7% males; mean age, 61.55±15 years), with left ventricular systolic dysfunction (left ventricular ejection fraction [LVEF] 20cm2 was 1188pg/mL (area under the receiver-operating characteristic curve [AUC] 0.83 [0.71–0.93], p<0.0001, sensitivity 77.6%, specificity 75%).ConclusionThe present study shows that plasma NT Pro-BNP levels is…
Transient chylomicronemia preceding the onset of insulin-dependent diabetes in a young girl with no humoral markers of islet autoimmunity
2004
OBJECTIVE: We investigated the possible causes of diabetes in a young child who presented with hyperglycemia associated with severe hypertriglyceridemia (>166 mmol/l), hypercholesterolemia (>38 mmol/l) and fasting chilomicrons. RESULTS: The patient did not have any of the HLA and autoantibody markers typically associated with type 1 diabetes. A glucose clamp failed to demonstrate insulin resistance (peripheral glucose utilization rate (M)=4.3 mg/kg per min) and there was no family history of type 2 diabetes or maturity onset diabetes in youth. Both fasting and stimulated C-peptide levels, including those in response to i.v. glucagon, were below the limit of detection. This is consiste…
