L'anglais des spécialités médicales
2015
International audience; Cet ouvrage vise à couvrir l'immense champ des spécialités médicales afin de permettre aux externes, aux internes et aux professionnels de santé en général de se familiariser avec les subtilités de la langue médicale spécialisée Chaque section dédiée à une spécialité comporte:- un lexique de l'anatomie propre à la spécialité médicale abordée, présenté sous forme de glossaire- un court lexique spécialisé de la physiologie- les mots-clés de la spécialité (généralités, signes et symptômes, maladies, traitements ...)- les principaux sigles et acronymes, particulièrement utiles pour lire un article de recherche spécialisé- les expressions les plus fréquemment utilisées lo…

Experiences with Blockade of the Renin System in Human Hypertension Using Converting Enzyme Inhibitor SQ 20,881 and Saralasin
1980
The development of agents which are capable of producing in vivo angiotensin II blockade has provided to investigators and clinicians alike the opportunity to determine and to quantify the extent to which the renin-angiotensin system participates in the maintenance of hypertensive states. High levels of plasma renin activity relative to the state of sodium balance have been documented in patients with malignant, surgically remediable renovascular hypertension and also in some patients with essential hypertension.1 The recent development of the angiotensin II analogue sar1-ala8-angiotensin II (saralasin) provided evidence to support the concept that these elevated renin levels are in fact pa…
Nephrotoxic drug burden among 1001 critically ill patients: impact on acute kidney injury.
2019
Abstract Background Nephrotoxic drug prescription may contribute to acute kidney injury (AKI) occurrence and worsening among critically ill patients and thus to associated morbidity and mortality. The objectives of this study were to describe nephrotoxic drug prescription in a large intensive-care unit cohort and, through a case–control study nested in the prospective cohort, to evaluate the link of nephrotoxic prescription burden with AKI. Results Six hundred and seventeen patients (62%) received at least one nephrotoxic drug, among which 303 (30%) received two or more. AKI was observed in 609 patients (61%). A total of 351 patients were considered as cases developing or worsening AKI a gi…
Prospective cohort study of early biosignatures of response to lithium in bipolar-I-disorders: overview of the H2020-funded R-LiNK initiative
2019
Abstract Background Lithium is recommended as a first line treatment for bipolar disorders. However, only 30% of patients show an optimal outcome and variability in lithium response and tolerability is poorly understood. It remains difficult for clinicians to reliably predict which patients will benefit without recourse to a lengthy treatment trial. Greater precision in the early identification of individuals who are likely to respond to lithium is a significant unmet clinical need. Structure The H2020-funded Response to Lithium Network (R-LiNK; http://www.r-link.eu.com/) will undertake a prospective cohort study of over 300 individuals with bipolar-I-disorder who have agreed to commence a …
Overexpression of nerve growth factor in peritoneal fluid from women with endometriosis may promote neurite outgrowth in endometriotic lesions
2011
To investigate the role of the nerve growth factor (NGF) in the endometriosis-associated innervation in the development of endometriosis- associated symptoms, 41 peritoneal fluid samples (PF) from patients with surgically and histologically proven endometriosis and 20 PF from patients with other gynecologic conditions were analyzed with Western blot and a novel in vitro model using dorsal root ganglia (DRG) to show neuronal outgrowth; endometrial cells also were analyzed. The results suggest that the PF of endometriosis patients and endometriotic lesions have neurotropic properties, because the Western blot analysis and the cell culture stainings showed NGF expression, and the neurite outgr…
Update on perioperative management of the child with asthma
2012
Asthma represents the leading cause of morbidity from a chronic disease among children. Dealing with this disease during the perioperative period of pediatric surgical procedures is, therefore, quite common for the anesthesiologist and other professionalities involved. Preoperative assessment has a key role in detecting children at increased risk of perioperative respiratory complications. For children without an optimal control of symptoms or with a recent respiratory tract infection elective surgery should be postponed, if possible, after the optimization of therapy. According to clinical setting, loco-regional anesthesia represents the desirable option since it allows to avoid airway ins…
Estradiol Stimulates Vasodilatory and Metabolic Pathways in Cultured Human Endothelial Cells
2009
Vascular effects of estradiol are being investigated because there are controversies among clinical and experimental studies. DNA microarrays were used to investigate global gene expression patterns in cultured human umbilical vein endothelial cells (HUVEC) exposed to 1 nmol/L estradiol for 24 hours. When compared to control, 187 genes were identified as differentially expressed with 1.9-fold change threshold. Supervised principal component analysis and hierarchical cluster analysis revealed the differences between control and estradiol-treated samples. Physiological concentrations of estradiol are sufficient to elicit significant changes in HUVEC gene expression. Notch signaling, actin cyt…
