Stereoselective block of hERG channel by (S)-methadone and QT interval prolongation in CYP2B6 slow metabolizers.

Methadone inhibits the cardiac potassium channel hERG and can cause a prolonged QT interval. Methadone is chiral but its therapeutic activity is mainly due to (R)-methadone. Whole-cell patch-clamp experiments using cells expressing hERG showed that (S)-methadone blocked the hERG current 3.5-fold more potently than (R)-methadone (IC50s (half-maximal inhibitory concentrations) at 37 degrees C: 2 and 7 microM). As CYP2B6 slow metabolizer (SM) status results in a reduced ability to metabolize (S)-methadone, electrocardiograms, CYP2B6 genotypes, and (R)- and (S)-methadone plasma concentrations were obtained for 179 patients receiving (R,S)-methadone. The mean heart-rate-corrected QT (QTc) was higher in CYP2B6 SMs (*6/*6 genotype; 439+/-25 ms; n=11) than in extensive metabolizers (non *6/*6; 421+/-25 ms; n=168; P=0.017). CYP2B6 SM status was associated with an increased risk of prolonged QTc (odds ratio=4.5, 95% confidence interval=1.2-17.7; P=0.03). This study reports the first genetic factor implicated in methadone metabolism that may increase the risk of cardiac arrhythmias and sudden death. This risk could be reduced by the administration of (R)-methadone.

Bloc atrioventriculaire complet sur borréliose de Lyme: aspects etectrocardiographiques, diagnostiques et microbiologiques [Atrioventricular heart block in Lyme disease]

Lyme disease is the most common tick-borne disease in Europe and in the United States. In comparison to dermatological, neurological and rheumatological manifestations, heart disease is quite rare. Atrioventricular heart block is nevertheless the most frequent cardiological manifestation. We hereby report the case of a patient with high degree heart block due to Lyme disease. We focus on the electrocardiographical evolution during antibiotic therapy, as well as on microbiological and diagnostic aspects. Lyme disease is a rare cause of conduction disturbances but it is treatable and potentially reversible.

Brachial or wrist blood pressure in obese patients : which is the best ?

RESUME L'obésité et l'hypertension atteignent des niveaux épidémiques aussi bien dans les pays industrialisés que dans ceux en voie de développement. La coexistence de ces deux pathologies est associée à un risque cardiovasculaire augmenté. Traditionnellement on mesure la pression artérielle (PA) au bras au moyen d'un brassard qui détermine la pression systolique et diastolique en utilisant soit la méthode auscultatoire ou oscillométrique. L'utilisation d'un brassard de taille standard chez le patient avec un tour de bras augmenté peut surestimer la pression artérielle. Il semble même qu'il existe un rapport idéal entre le tour de bras, et la taille du brassard La mesure à domicile de la pression artérielle avec des appareils validés donne des valeurs de la PA valables. Plusieurs appareils existent sur le marché et depuis quelques années les appareils de mesure de la PA au poignet font leur apparition sur le marché. Cette étude vise à comparer chez des sujets sains et obèses les valeurs de PA obtenues au poignet avec celles obtenues au bras en utilisant deux appareils validés l'OMRON HEM 705-CP et l'OMRON R6. L'OMRON HEM 705-CP permet l'utilisation soit d'un brassard standard (13x30 cm) ou d'un brassard large (16x38 cm), et l'OMRON R6 mesure la PA au poignet. Nous avons comparé un groupe de sujets obèses [Body Mass Index (BMI) >35kg/m2] avec un groupe de sujets sains (BMI <25kg/m2). Ont été exclues de l'étudé les personnes prenant un traitement antihypertenseur ainsi que celles souffrant d'arythmies. La PA a été mesurée en position assise avec le bras gauche sur une table à hauteur du coeur. Un brassard large a été employé pour les sujets obèses et un brassard standard pour les sujets sains. Trois mesures ont été effectuées, la première après une pause de 5 min et chacune des suivantes avec un intervalle de 2 min. La pression d'inflation maximale a été fixée à 170 mmHg. Nous avons utilisé la formule proposée par Marks LA et al pour déterminer si le rapport entre la taille des brassards fournis avec l'OMRON .HEM 705-CP et le tour de bras de nos sujets était optimal (taille du brassard = 9.34 x log10 taille du bras). Nos résultats ne montrent pas de différence statistiquement significative de la PA diastolique entre les deux groupes, qu'elle soit mesurée au bras ou au poignet. La PA systolique mesurée au bras s'est par contre avérée significativement plus basse chez les sujets obèses que chez les sujets sains. Aucune différence n'a été trouvée lorsque la mesure est effectuée au poignet. En utilisant la formule fournie par Marks le rapport entre taille du brassard (large chez les obèses) et tour de bras a été de 10.30±30 chez les sujets obèses et 9.630.45 chez les sujets sains (p<0.001). Le rapport entre tour de bras et brassard chez les sujets obèses est nettement au-dessus de la valeur optimale, ce qui suggère une possible sous-estimation de la PA systolique chez ces sujets. Ces résultats suggèrent qu'il existe un risque de sous-estimer la PA chez le patient obèse lors de l'utilisation d'un brassard large. Cette erreur pourrait être réduite par l'utilisation d'appareils de mesure au poignet. validés chez le sujet obèse.

Maternal and Child Health Services Title V Block Grant State Narrative for Iowa Application for 2015 Annual Report for 2013, September 21, 2014

Key factors that provide context for the state's Maternal and Child Health (MCH) annual report and state plan are highlighted in this overview. This section briefly outlines Iowa's demographics, population changes, economic indicators and significant public initiatives. Major strategic planning efforts affecting development of program activities are also identified.

Iowa’s Title V Block Grant Executive Summary, 2013

Title V of the Social Security Act is the longest-standing public health legislation in American history. Enacted in 1935, Title V is a federal-state partnership that promotes and improves maternal and child health (MCH). According to each state’s unique needs, Title V supports a spectrum of services, from infrastructure building services like quality assurance and policy development, to gap-filling direct health care services. Title V resources are directed towards MCH priority populations: pregnant women, mothers, infants, women of reproductive years, children and adolescents and children and youth with special health care needs.

Palaeozoic deformation and magmatism in the northern area of the Anatolide block (Konya), witness of the Palaeotethys active margin

The study area. located north of Konva (Central Turkey), is composed of Silurian to Cretaceous metamorphosed rocks. The lower unit of the oldest formation (Silurian-Early Permian) is mostly made up of Silurian-Early Carboniferous metacarbonates. These rocks pass laterally and vertically to Devonian-Early Permian series having continental margin, shallow water and pelagic characteristics. They are intruded or juxtaposed to different kinds of metamagmatic rocks. which show MORB. continental arc and within plate characteristics. The Palaeozoic units are covered unconformably by Triassic-Cretaceous metasedimentary units. All these rocks are overthrusted by Mesozoic ophiolites. The Palaeozoic sequence can be seen as a northern Palaeotethys passive, then active margin. The northward subduction of the Palaeotethys ocean during the Carboniferous-Triassic times, induced the development of a magmatic arc and fore-arc sequence (Carboniferous-Permian). Before the Early Triassic (?Late Permian) time. the fore-arc sequence was uplifted above sea level and eroded. The Triassic sequences are regarded as marking the onset of back-arc opening and detachment of the Anatolian Konya block from the active Eurasian margin. Finally. a suture zone formed during the Carman between the Konya region and the Menderes-Tauride Cimmerian block due to the closing of Palaeotethvs. This geodynamic evolution can be correlated with the evolution of the Karaburun sequence in western Turkey.

Block structured dynamics and neuronal coding

When certain control parameters of nervous cell models are varied, complex bifurcation structures develop in which the dynamical behaviors available appear classified in blocks, according to criteria of dynamical likelihood. This block structured dynamics may be a clue to understand how activated neurons encode information by firing spike trains of their action potentials.

Fc block treatment, dead cells exclusion, and cell aggregates discrimination concur to prevent phenotypical artifacts in the analysis of subpopulations of tumor-infiltrating CD11b(+) myelomonocytic cells.

It is well established that cancer cells can recruit CD11b(+) myeloid cells to promote tumor angiogenesis and tumor growth. Increasing interest has emerged on the identification of subpopulations of tumor-infiltrating CD11b(+) myeloid cells using flow cytometry techniques. In the literature, however, discrepancies exist on the phenotype of these cells (Coffelt et al., Am J Pathol 2010;176:1564-1576). Since flow cytometry analysis requires particular precautions for accurate sample preparation and trustable data acquisition, analysis, and interpretation, some discrepancies might be due to technical reasons rather than biological grounds. We used the syngenic orthotopic 4T1 mammary tumor model in immunocompetent BALB/c mice to analyze and compare the phenotype of CD11b(+) myeloid cells isolated from peripheral blood and from tumors, using six-color flow cytometry. We report here that the nonspecific antibody binding through Fc receptors, the presence of dead cells and cell doublets in tumor-derived samples concur to generate artifacts in the phenotype of tumor-infiltrating CD11b(+) subpopulations. We show that the heterogeneity of tumor-infiltrating CD11b(+) subpopulations analyzed without particular precautions was greatly reduced upon Fc block treatment, dead cells, and cell doublets exclusion. Phenotyping of tumor-infiltrating CD11b(+) cells was particularly sensitive to these parameters compared to circulating CD11b(+) cells. Taken together, our results identify Fc block treatment, dead cells, and cell doublets exclusion as simple but crucial steps for the proper analysis of tumor-infiltrating CD11b(+) cell populations.

Neonatal lupus erythematosus with congenital heart block and severe heart failure due to myocarditis and endocardititis of the mitral valve.

We report a case of neonatal lupus erythematosus (NLE) with congenital heart block and severe myocardial failure, which was followed from the 25th week of gestation because of fetal bradycardia. The child was delivered at the 37th week of gestation by elective cesarean section because of echocardiographically documented heart enlargement, pericardial effusion and moderate insufficiency of the mitral and tricuspid valves. In spite of immediate pacing, intubation and supportive treatment, the newborn developed progressive heart failure. Echocardiography showed endocarditis of the mitral valve and diffuse myocarditis. The heart failure resolved under steroid treatment. Our experience supports the early use of steroids in treating myocarditis due to NLE. Intrauterine steroid treatment in the presence of fetal hydrops and congenital heart block is discussed.
