Relations of Sex to Diagnosis and Outcomes in Acute Coronary Syndrome

2018

Background The atypical presentation of women with acute coronary syndrome ( ACS ) has been related to delayed diagnosis and treatment, which may explain worse outcome compared with men. Methods and Results We analyzed pooled data of 2520 patients of 2 prospective cohorts in terms of differences in presentation and management of women and men suggestive of ACS . Using logistic regression, we established 2 diagnostic models and tested their diagnostic performance in both sexes separately. Sex‐specific differences in management of patients with ACS were ascertained and a 2‐year follow‐up was performed. Women were older than men (median 67 versus 61 years, P =0.001), had more often dyspnea (2…

Contemporary differences between men and women with acute coronary syndromes: CIAM multicenter registry.

2019

AIM Differences exist in the diagnosis and treatment of acute coronary syndrome (ACS) between men and women. However, recent advancements in the management of ACSs might have attenuated this sex gap. We evaluated the status of ACS management in a multicenter registry in 10 tertiary Spanish hospitals. METHODS We enrolled 1056 patients in our study, including only those with type 1 myocardial infarctions or unstable angina presumably not related to a secondary cause in an 'all-comers' design. RESULTS The women enrolled (29%) were older than men (71.0 ± 12.8 vs. 64.0 ± 12.3, P = 0.001), with a higher prevalence of hypertension (71.0 vs. 56.5%, P < 0.001), insulin-treated diabetes (13.7 vs. 7.9…

Clinical profile and predictors of in-hospital mortality among older patients hospitalised for COVID-19.

2020

Abstract Background the coronavirus disease 2019 (COVID-19) is characterized by poor outcomes and mortality, particularly in older patients. Methods post hoc analysis of the international, multicentre, ‘real-world’ HOPE COVID-19 registry. All patients aged ≥65 years hospitalised for COVID-19 were selected. Epidemiological, clinical, analytical and outcome data were obtained. A comparative study between two age subgroups, 65–74 and ≥75 years, was performed. The primary endpoint was all cause in-hospital mortality. Results about, 1,520 patients aged ≥65 years (60.3% male, median age of 76 [IQR 71–83] years) were included. Comorbidities such as hypertension (69.2%), dyslipidaemia (48.6%), card…

Elevated advanced oxidation protein products (AOPPs) indicate metabolic risk in severely obese children.

2012

Abstract Background and aims The assessment of oxidative stress may aid in the identification of subsequent metabolic risk in obese children. The objective of this study was to determine whether the plasma level of advanced oxidation protein products, analyzed with a recently proposed modified assay that involves a delipidation step (mAOPPs), was related to metabolic risk factors (MRFs) in severely obese children. Methods and results The plasma levels of mAOPPs were determined by spectrophotometry in 54 severely obese and 44 healthy children. We also measured lipid peroxidation biomarkers (thiobarbituric acid-reactive substances, malondialdehyde, and 8-isoprotane F 2α ) and sulfhydryl group…

The Aromatase Gene CYP19A1: Several Genetic and Functional Lines of Evidence Supporting a Role in Reading, Speech and Language

2012

Inspired by the localization, on 15q21.2 of the CYP19A1 gene in the linkage region of speech and language disorders, and a rare translocation in a dyslexic individual that was brought to our attention, we conducted a series of studies on the properties of CYP19A1 as a candidate gene for dyslexia and related conditions. The aromatase enzyme is a member of the cytochrome P450 super family, and it serves several key functions: it catalyzes the conversion of androgens into estrogens; during early mammalian development it controls the differentiation of specific brain areas (e.g. local estrogen synthesis in the hippocampus regulates synaptic plasticity and axonal growth); it is involved in sexua…

Molecular diagnosis of hypobetalipoproteinemia: an ENID review.

2007

Abstract Primary hypobetalipoproteinemia (HBL) includes a group of genetic disorders: abetalipoproteinemia (ABL) and chylomicron retention disease (CRD), with a recessive transmission, and familial hypobetalipoproteinemia (FHBL) with a co-dominant transmission. ABL and CRD are rare disorders due to mutations in the MTP and SARA2 genes, respectively. Heterozygous FHBL is much more frequent. FHBL subjects often have fatty liver and, less frequently, intestinal fat malabsorption. FHBL may be linked or not to the APOB gene. Most mutations in APOB gene cause the formation of truncated forms of apoB which may or may be not secreted into the plasma. Truncated apoBs with a size below that of apoB-3…

Cell type-specific circuits of cortical layer IV spiny neurons

2003

Sensory signal processing in cortical layer IV involves two major morphological classes of excitatory neurons: spiny stellate and pyramidal cells. It is essentially unknown how these two cell types are integrated into intracortical networks and whether they play different roles in cortical signal processing. We mapped their cell-specific intracortical afferents in rat somatosensory cortex through a combination of whole-cell patch-clamp recordings and caged glutamate photolysis. Spiny stellate cells received monosynaptic excitation and inhibition originating almost exclusively from neurons located within the same barrel. Pyramidal cells, by contrast, displayed additional excitatory inputs fr…

Diagnostic accuracy of 64-slice computed tomography coronary angiography in patients with low-to-intermediate risk

2007

Purpose. Our aim was to evaluate the diagnostic accuracy of 64- slice computed tomography coronary angiography (MSCT-CA) for detecting significant stenosis (≥50% lumen reduction) in a population of patients at low to intermediate risk. Materials and methods. We studied 72 patients (38 men, 34 women, mean age 53.9±8.0 years) with atypical or typical chest pain and stratified in the low- to intermediate risk category. MSCT-CA (Sensation 64 Cardiac, Siemens, Germany) was performed after IV administration of 100 ml of iodinated contrast material (Iomeprol 400 mgI/ml, Bracco, Italy). Two observers, blinded to the results of conventional coronary angiography (CAG), assessed the MSCT-CA scans in c…

Prevalence of coronary artery intramyocardial course in a large population of clinical patients detected by multislice computed tomography coronary a…

2008

Background: Intramyocardial course, an inborn coronary anomaly, is defined as a segment of a major epicardial coronary artery that runs intramurally through the myocardium; in particular, we distinguish myocardial bridging, in which the vessel returns to an epicardial position after the muscle bridge, and intramyocardial course, which is described as a vessel running and ending in the myocardium. Purpose: To evaluate the prevalence of myocardial bridging and intramyocardial course of coronary arteries as defined by multidetector computed tomography (MDCT) angiography. Material and Methods: The study population consisted of 242 consecutive patients (211 men, 31 women; mean age 59±6 years) w…
