Impact of carotid plaque screening on smoking cessation and other cardiovascular risk factors: a randomized controlled trial

Screening of peripheral atherosclerosis is increasingly used, but few trials have examined its clinical impact. We aimed to assess whether carotid plaque screening helps smokers to improve their health behaviors and cardiovascular risk factors.

L’industrie cinématographique du Cameroun : évaluation et perspectives

L’industrie cinématographique africaine d’aujourd’hui connaît de grandes avancées dans de nombreux pays d’Afrique. Seulement, autant certains pays africains connaissent de grandes avancées, autant d’autres pays voient leur industrie cinématographique traîner le pas. Le Cameroun est un exemple qui illustre à souhait ces pays qui sont à la traîne. Deux constats s’imposent à nous dans ce cas d’espèce. D’un côté, le Ministère de la Culture semble s’essouffler par le rôle qui lui incombe. De ce fait, il est de moins en moins actif et très peu représenté sur le terrain. De l’autre côté, nous observons çà et là de multiples activités. Des festivals, de long et court métrages organisés par des camerounais, ainsi que des rencontres cinématographiques mises sur pied en partenariat avec les représentations culturelles de pays étrangers en présence sur le territoire. Ces initiatives diverses malgré l’atmosphère peu favorable du pays parviennent à impulser une certaine dynamique. Notons tout de même que ces actions restent cantonnées dans les deux principales villes que sont Yaoundé et Douala. Après ce bref aperçu du tableau cinématographique camerounais, deux questions s’imposent à nous : Quelle appréciation peut-on faire du cinéma au Cameroun aujourd’hui ? Quel avenir pour celui-ci ? Telles sont les deux préoccupations auxquelles nous essaierons d’apporter quelques éléments de réponses dans cette étude. // Mots clés : cinéma, Cameroun, bilan, perspectives, initiatives, industrie cinématographique.

La valeur de la femme dans la société traditionnelle Bətí-faŋ

Le Bətí-faŋ est une langue parlée dans la sous-région Afrique centrale, notamment au Cameroun, en Guinée Équatorial, au Gabon et à Sao Tomé et Principe. Le Bətí-faŋ est un peuple fier, avec un passé culturel à la fois important et mystérieux. Certains de ses aspects culturels aujourd'hui sont perdus, dû, en grande partie, à l'action de la religion occidentale et de la colonisation. De nombreuses pratiques alors usitées se voient interdites, à cause des idées préconçues et des interprétations subjectives qui sont accordées à ses pratiques. De même, la valeur et la place que l'Homme Bətí accorde à la femme dans la société s’en trouve pervertie, ceci pour servir les desseins de l’oppresseur. Cet aspect en particulier de la société traditionnelle Bətí-faŋ a souvent porté à polémique. Ces préjugés et interprétations, sont pour la plupart, fréquemment avancées sans que la philosophie de cette société, le contexte, l'époque, et le symbolisme des dits effets ou individus ne soient pris en compte. Cet article va s’arrêter sur la femme Bətí en particulier. Nous essaierons de faire ressortir le symbolisme qui entoure celle-ci. Nous insisterons sur la valeur, ainsi que sur la place et l'importance accordées à celle-ci dans la société traditionnelle des seigneurs de la forêt. Pour se faire, nous porterons notre attention sur les formes de mariages qui ont marquées cette époque. Nous nous étendrons aussi sur l’importance accordée au nombre, ainsi que son impact sur la vie culturelle de l'« Atí ». Nous brosserons enfin, un petit aperçu des rites spécifiques aux femmes qui dénotent de leur impact sur le quotidien des seigneurs de la forêt.

Systemic and pulmonary vascular dysfunction in children conceived by assisted reproductive technologies

Assisted reproductive technology (ART) involves the manipulation of early embryos at a time when they may be particularly vulnerable to external disturbances. Environmental influences during the embryonic and fetal development influence the individual's susceptibility to cardiovascular disease, raising concerns about the potential consequences of ART on the long-term health of the offspring.

Combined anatomical and clinical factors for the long-term risk stratification of patients undergoing percutaneous coronary intervention: the Logistic Clinical SYNTAX score

The SYNTAX score (SXscore), an anatomical-based scoring tool reflecting the complexity of coronary anatomy, has established itself as an important long-term prognostic factor in patients undergoing percutaneous coronary intervention (PCI). The incorporation of clinical factors may further augment the utility of the SXscore to longer-term risk stratify the individual patient for clinical outcomes.

Determinants of prognostically relevant intracoronary electrocardiogram ST-segment shift during coronary balloon occlusion

The prognostic relevance of quantitative an intracoronary occlusive electrocardiographic (ECG) ST-segment shift and its determinants have not been investigated in humans. In 765 patients with chronic stable coronary artery disease, the following simultaneous quantitative measurements were obtained during a 1-minute coronary balloon occlusion: intracoronary ECG ST-segment shift (recorded by angioplasty guidewire), mean aortic pressure, mean distal coronary pressure, and mean central venous pressure (CVP). Collateral flow index (CFI) was calculated as follows: (mean distal coronary pressure minus CVP)/(mean aortic pressure minus CVP). During an average follow-up duration of 50 ± 34 months, the cumulative mortality rate from all causes was significantly lower in the group with an ST-segment shift <0.1 mV (n = 89) than in the group with an ST-segment shift ≥0.1 mV (n = 676, p = 0.0211). Factors independently related to intracoronary occlusive ECG ST-segment shift <0.1 mV (r(2) = 0.189, p <0.0001) were high CFI (p <0.0001), intracoronary occlusive RR interval (p = 0.0467), right coronary artery as the ischemic region (p <0.0001), and absence of arterial hypertension (p = 0.0132). "High" CFI according to receiver operating characteristics analysis was ≥0.217 (area under receiver operating characteristics curve 0.647, p <0.0001). In conclusion, absence of ECG ST-segment shift during brief coronary occlusion in patients with chronic coronary artery disease conveys a decreased mortality and is directly influenced by a well-developed collateral supply to the right versus left coronary ischemic region and by the absence of systemic hypertension in a patient's history.

Echocardiogram versus cardiac magnetic resonance imaging for assessing systolic function of subaortic right ventricle in adults with complete transposition of great arteries and previous atrial switch operation

In adults with congenital heart disease and a systemic right ventricle, subaortic ventricular systolic dysfunction is common. Echocardiographic assessment of systolic right ventricular (RV) function in these patients is important but challenging. The aim of the present study was to assess the reliability of conventional echocardiographic RV functional parameters to quantify the systolic performance of a subaortic right ventricle. We compared 56 contemporary echocardiograms and cardiac magnetic resonance studies in 37 adults, aged 26.9 ± 7.4 years, with complete transposition and a subaortic right ventricle. The fractional area change (FAC), lateral tricuspid annular plane systolic excursion, lateral RV systolic motion velocities by tissue Doppler, RV myocardial performance index, and the rate of systolic RV pressure increase (dp/dt) measured across the tricuspid regurgitant jet were assessed by echocardiography and correlated with the cardiac magnetic resonance-derived RV ejection fraction (EF). The mean RVEF was 48.0 ± 7.8%. FAC (r(2) = 0.206, p = 0.001) and dp/dt (r(2) = 0.173, p = 0.009) significantly correlated with RVEF, and the other nongeometric echocardiographic parameters failed to show a significant correlation with RVEF by linear regression analysis. FAC <33% and dp/dt <1,000 mm Hg/s identified a RVEF of <50% with a sensitivity of 77% and 69% and a specificity of 58% and 87%, respectively. In conclusion, in patients with a systemic right ventricle, routine nongeometric echocardiographic parameters of RV function correlated weakly with cardiac magnetic resonance-derived EF. RV FAC and the measurement of the rate of systolic RV pressure increase (dp/dt) should be preferentially used to assess systemic systolic function in adult patients with a subaortic right ventricle.

Coronary collaterals and risk for restenosis after percutaneous coronary interventions: a meta-analysis

The benefit of the coronary collateral circulation (natural bypass network) on survival is well established. However, data derived from smaller studies indicates that coronary collaterals may increase the risk for restenosis after percutaneous coronary interventions. The purpose of this systematic review and meta-analysis of observational studies was to explore the impact of the collateral circulation on the risk for restenosis.
