Ultrasonography in Heart Failure: A Story that Matters
2019
Abstract Heart failure (HF) is a clinical syndrome caused by structural and/or functional cardiac abnormalities, resulting in a reduced cardiac output and/or elevated intracardiac pressures at rest or during stress. It is the leading cause of hospitalization in Internal Medicine departments. This article aims at reviewing evidence of the importance of ultrasound in HF both for hospitalized patients and in the follow-up. Ultrasound may be used as a recovery monitoring instrument at the bedside and also as a global cardiovascular assessment tool for these patients. HF represents an exciting opportunity to create an integrative ultrasound approach in Internal Medicine and/or Geriatric departme…
Bicycling to school improves the cardiometabolic risk factor profile:a randomised controlled trial
2012
Objectives To investigate whether bicycling to school improves cardiometabolic risk factor profile and cardiorespiratory fitness among children. Design Prospective, blinded, randomised controlled trial. Setting Single centre study in Odense, Denmark Participants 43 children previously not bicycling to school were randomly allocated to control group (n=20) (ie, no change in lifestyle) or intervention group (ie, bicycling to school) (n=23). Primary and secondary outcome measures Change in cardiometabolic risk factor score and change in cardiorespiratory fitness. Results All participants measured at baseline returned at follow-up. Based upon intention-to-treat (ITT) analyses, clustering of car…
Polyvascular subclinical atherosclerosis in familial hypercholesterolemia: The role of cholesterol burden and gender
2019
International audience; BACKGROUND AND AIM:Heterozygous familial hypercholesterolemia (HeFH) is a genetic disease characterized by a heterogeneous phenotype. The assessment of cardiovascular (CV) risk is challenging for HeFH. Cholesterol burden (CB) allows to estimate the lifelong exposure to high levels of cholesterol. The aim of this study was to analyze the distribution of subclinical atherosclerosis and the relationship between atherosclerosis and the CB in a sample of HeFH patients, focusing on sex-related differences.METHODS AND RESULTS:154 asymptomatic HeFH subjects underwent coronary-artery-calcium score (CACs) and Doppler ultrasound of carotid and femoral arteries. Yearly lipid pro…
Life-time risk factors and progression of carotid atherosclerosis in young adults: the Cardiovascular Risk in Young Finns study.
2010
Aims The aim of this study is to evaluate whether childhood risk factors are associated with a 6-year change in carotid intima-media thickness (IMT) in young adulthood independent of the current risk factors. Methods and results The Cardiovascular Risk in Young Finns cohort consisted of 1809 subjects who were followed-up for 27 years since baseline (1980, age 3–18 years) and having carotid IMT measured both in 2001 and 2007. Cardiovascular risk factors were assessed repeatedly since childhood. A genotype risk score was calculated using 17 newly identified genetic variants associating with cardiovascular morbidity. The number of childhood risk factors (high LDL-cholesterol, low HDL-cholester…
Electrocardiographic abnormalities, preclinical carotid atherosclerosis and cardiovascular risk in an apparently healthy real-world population. Data …
2021
Background: Cardiovascular diseases (CVDs) represent important causes of morbidity and mortality. Our study aimed to evaluate cardiovascular risk using the EuroSCORE, ECG and carotid ultrasound for prevention purpose in a population of companions aged 50-70 years, asymptomatic and without CVD. Methods: History of CVD, risk factors (RF), ECG and carotid ultrasound were evaluated. Intima-media thickness (IMT) was defined as wall thickness >0.9 mm, while focal thickening ≥1.5 mm protruding into the lumen as asymptomatic carotid plaque (ACP). Results: Totally, 1860 subjects were screened. 393 (21.1%) had no RF, 780 (42%) hypertension, 571 (30.7%) hypercholesterolemia, 557 (29.9%) diabetes, 4…
El Terç del Cartoixà de Joan Roís de Corella. Edició i estudi
2016
La tesi doctoral "El Terç del Cartoixà de Joan Roís de Corella. Edició i estudi" fixa el text d'aquest incunable i el compara a doble columna amb el text del qual és deutor, la Vita Christi de Ludolf de Saxònia. La datació de l'obra, entre febrer i març de 1495, i l'atribució a un taller, el de Hagenbach-Hutz a la ciutat de València, es realitza per mitjà de l'anàlisi de dades codicològiques i d'història de la impremta en aquesta ciutat. Aquesta anàlisi permet també situar adequadament el projecte d'edició dels quatre volums que conformen el Cartoixà de Corella a finals del segle XV. La comparació del text català amb el llatí permet descobrir les diferents tècniques usades per l'autor valen…
Immediate and long-term microshear bond strength of resin-based cements to core build-up materials
2021
Background To evaluate the microshear bond strength (μ-SBS) between resin-based cements and core build-up materials after water storage. Material and methods Cylinders (1x1 mm) of conventional dual-cure resin cement (RelyX ARC, 3M ESPE), universal dual-cure resin cement (RelyX Ultimate, 3M ESPE) or self-adhesive resin cement (RelyX U200, 3M ESPE) were adhered to disks (6x2 mm) made with commercial core build-up materials (Bis-Core, Bisco or LuxaCore Z, DMG) or conventional nanocomposite resin (Filtek Z350 XT, 3M ESPE). The specimens (n=10) were submitted to μ-SBS test using a universal testing machine and fracture pattern analysis at 48 hours or after 9 months of water storage. The data wer…
Bond strength evaluation of the veneering-core ceramics bonds.
2009
The purpose of this study was to determine whether the bond of veneering porcelain to a ceramic core in bilayered ceramics was similar to that of the metal ceramic control of well known behaviour. Six groups of nine specimens each were fabricated, whose dimensions were 15 mm long and 8 mm in diameter at the core, and 2 mm long and 8 mm in diameter for the veneer. The groups were GR. 1 (control group): CrNi alloy/d.SIGN (Ivoclar), GR. 2: IPS e.maxPress/IPS e.maxCeram (Ivoclar), GR. 3: IPS e.maxZirCad/ IPS e.maxZirPress (Ivoclar), GR. 4: IPS e.maxZirCad/IPS e.maxCeram (Ivoclar), GR. 5: Lava Frame (3M ESPE)/ Lava Ceram (3M ESPE) and GR. 6: Lava Frame (3M ESPE)/IPS e.maxCeram (Ivoclar). A shear…
205 Minimally invasive approaches in locally advanced cervical cancer patients undergoing radical surgery after chemoradiotherapy: a propensity score…
2020
Objectives To evaluate the oncological and surgical outcome of minimally invasive radical surgery (MI-RS) compared to open radical surgery (O-RS) in locally advanced cervical cancer (LACC) after preoperative chemoradiation (CT/RT). Methods Data relative to stage IB2-IVA cervical cancer patients managed by CT/RT and RS were retrospectively analyzed. Results Starting from 686 patients, the propensity score matching resulted in 462 cases (231 per group), balanced for FIGO stage, lymph node status, histotype, tumor grade and clinical response to CT/RT. Overall, 107 recurrences were registered with no difference in the pattern of recurrences between the two surgical approaches. The 5-year diseas…
Erosion en milieu sableux cultivé au Niger : dynamique actuelle et passée en liaison avec la pression anthropique et les changements climatiques
2011
Sahelian ecosystems, especially those installed on sandy soils react very quickly and intensely to small climatic changes. In this semi-arid area, wind erosion which occurs mainly on cultivated millet fields and is threatening the sustainable use of land resources. Furthermore, the rapid population growth and the severe droughts of the twentieth century have had important impacts on ecosystems. To better manage this fragile environment, it is important first to understand how it works. This thesis was included in the framework of the AMMA project (African Monsoon Multidisciplinary Analyses) and was in the heart of a CORUS 2 (Coopération pour la Recherche Universitaire et Scientifique) progr…
