P852Frequency and prognosis of type 2 myocardial infarction vs non ischemic myocardial injury: large observational study from an emergency department

2019

Abstract Background Type 2 Myocardial Infarction (T2MI), due to myocardial oxygen supply-demand mismatch in the absence of atherothrombosis and non-ischemic myocardial injury (NIMI), corresponding to troponin elevation without overt ischemia, are emerging concepts which are suspected to be common in patients hospitalized. However, their respective frequencies, risk profiles and short term prognosis in current routine clinical practice of emergency unit remains to be investigated. Methods Among the medical records of all the patients admitted from January 2014 to December 2016 in a university hospital emergency unit (n=82 543), patients with elevated troponin Ic (≥0.10μg/L) (n=4568) were sys…

1539 Length of Hospital Stay in Children with Acute Viral Pneumonia Treated with Corticosteroids, A Retrospective Study

2012

Background Corticosteroids with or without ephedrine may have positive effects in viral pneumonia treatment accelerating the time to resolution of symtpoms but the evidence is not strong enough to make specific recommandations. Objectives Evaluating the hospital length stay of the children with viral pneumonia treated with corticosteroids, single or in combination with ephedrine. Material and Methods The retrospective study included pacients admitted in our clinic with viral pneumonia during 2011. From 167 cases, 78 cases were selected according to specific criteria: patients having received cortisone (hydrocortisone hemisuccinate and/or fluticasone propionate) associated or not with ephedr…

Mitochondria as a Target for Future Diabetes Treatments

2015

Diabetes mellitus is rapidly becoming the world’s most dangerous serial killer. Type 1 diabetes (T1D) is a currently incurable autoimmune disease marked by progressive, and eventually exhaustive, destruction of the insulin-producing pancreatic beta cells. Type 2 diabetes (T2D) describes the combination of insulin resistance in peripheral tissue, insufficient insulin secretion from the pancreatic beta cells, and excessive glucagon secretion from the pancreatic alpha cells. T1D as well as severe cases of T2D are treated with insulin replacement, which can merely be considered as life support for the acute phases of the disease. Islet replacement of insulin-producing pancreatic beta cells repr…

Mitochondrial complex I impairment in leukocytes from polycystic ovary syndrome patients with insulin resistance.

2009

Insulin resistance is a feature of polycystic ovary syndrome (PCOS) and is related to mitochondrial function.Our objective was to assess mitochondrial function by evaluating mitochondrial oxygen (O(2)) consumption, reactive oxygen species (ROS) production, levels of glutathione (GSH), the oxidized glutathione/GSH ratio, TNFalpha levels, and membrane potential. Additionally, we have evaluated mitochondrial complex I as a target of the oxidative stress responsible for PCOS in polymorphonuclear cells.This was a prospective controlled study conducted in an academic medical center.The study population consisted of 20 lean reproductive-age women with PCOS and 20 body composition-matched controls.…

Phenotypic variation in hyperandrogenic women influences the findings of abnormal metabolic and cardiovascular risk parameters.

2005

In hyperandrogenic women, several phenotypes may be observed. This includes women with classic polycystic ovary syndrome (C-PCOS), those with ovulatory (OV) PCOS, and women with idiopathic hyperandrogenism (IHA), which occurs in women with normal ovaries. Where other causes have been excluded, we categorized 290 hyperandrogenic women who were seen consecutively for this complaint between 1993 and 2004 into these three subgroups. The aim was to compare the prevalence of obesity, insulin resistance, and dyslipidemia as well as increases in C-reactive protein and homocysteine in these different phenotypes with age-matched ovulatory controls of normal weight (n = 85) and others matched for body…

Determinants of elevated carbohydrate antigen 125 in patients with severe symptomatic aortic valve stenosis referred for transcatheter aortic valve i…

2018

Elevated carbohydrate antigen 125 (CA125) predicts adverse outcome after transcatheter aortic valve implantation (TAVI). While known underlying pathophysiological mechanisms of elevated CA125 include serosal effusions and inflammatory stimuli, clinical determinants associated with elevated CA125 in patients referred for TAVI remain unknown. Therefore, we investigated clinical, laboratory and echocardiographic determinants of elevated CA125 in patients with severe aortic valve stenosis referred for TAVI.This study includes 650 patients with severe aortic stenosis referred for TAVI. Baseline CA125 was determined by an immunoassay and dichotomized (elevated versus normal) based on the manufact…

Is prolonged febrile syndrome associated with reactive thrombocytosis a possible association in the diagnosis of Takayasu’s arteritis? A case report

2021

Takayasu’s arteritis is a rare, systemic, inflammatory vasculitis of large blood vessels with an unknown aetiology that more frequently affects women of childbearing age with progression to stenosis, fibrosis or thrombogenesis. Clinical manifestations are associated either with inflammation of the vascular wall (including fever, myalgia, arthralgia, weight loss) or the development of aneurysms and extensive vascular lesions, which creates challenges for a differential diagnosis. This current report presents the case of a female Caucasian patient, aged 23 years, that presented herself repetitively at the hospital reporting symptoms including fever, productive cough, myalgia associated with …

Nitrate therapy: new aspects concerning molecular action and tolerance.

2011

Although the short-term vasodilatory properties of organic nitrates are potent and well known, a number of vascular and extravascular changes have been shown to compromise their hemodynamic effects on long-term administration. Among these changes, systemic phenomena such as neurohormonal activation and intravascular volume expansion1 as well as specific vascular changes such as increased vascular superoxide (O2·−) production,2 increased sensitivity to vasoconstrictors,3 and decreased responsiveness to nitric oxide (NO) donors4,5 have long been identified as playing a role. Several hypotheses have been proposed to explain these abnormalities, and over the last 15 years, our groups have focus…
