Does gender really matter in cathlab

Purpose: Results of some PCI clinical trials indicated more procedure related complications and worse clinical outcomes in women than men, but due to a lower representation of female patients this question still remains open. We aimed toinvestigate characteristics and early and late clinical outcomes in female patients as compared to male when treated in a real life setting with a new generation DES.Methods: Among 3069 consecutive patients treated with Nobori DES, and enrolled in NOBORI 2 study, 675 were female. The primary endpoint of the study is target lesion failure (TLF), a composite of cardiac death, MI and target lesion revascularization (TLR) at 12 months. Data are entered in an electronic database; all adverse events are adjudicated by an independent clinical event committee and independent corelabs analyse all angiograms.Results: Compared to male patients, female patients were significantly older (68±10 vs ± 63±11 years; p<0.001), had higher incidence of diabetes (37% vs 27%; p<0.001) and hypertension (75% vs 66%; p<0.001), but lower frequency of previous MI, PCI/CABG and smoking history. Lesion characteristics were similar in two genders, except for lesions located at bifurcation which were more frequent inmale patients (22% vs 15% inmale and female patients respectively; p<0.001). Majority of QCA assessed parameters were similar with the exception for RVD, post-procedure MLD in-segment and %DS in-stent which were significantly lower in female patients (p<0.05 for all). In table 1 results at 6 months follow-up are presented and at the time of presentation 1 year results will be available. Table 1. Clinical results at 6 months follow-up Male (n=2394) Female (n=675) P value Cardiac Death 12 (0.5%) 5 (0.7%) 0.5550 MI 5 (2.1%) 4 (1.3%) 0.5089 TLR rate 17 (0.7%) 13 (1.9%) 0.0124 TLF rate 44 (1.8%) 17 (2.5%) 0.2745 Stent Thrombosis 12 (0.5%) 6 (0.9%) 0.2548Conclusions: Results indicate that there are differences in the demographics and risk factors in female and male patient's population. The frequency of adverse events at 6 months is low in both populations, showing trend toward slightly higher rate in female patients, particularly for target lesion revascularization.

La coordination des dirigeants économiques face à la financiarisation : gouvernance d'entreprise, relations industrielles et élites dirigeantes dans l'industrie suisse des machines, de l'électrotechnique et de la métallurgie (1970-2008)

Résumé Cette recherche analyse les transformations de la gouvernance d'entreprise et des relations industrielles entre 1970 et 2008 dans le contexte suisse, en mettant l'accent sur les changements survenus depuis les années 1990. Elle se centre sur le secteur de l'industrie des machines, de l'électrotechnique et de la métallurgie -noyau historique du capitalisme helvétique et principal employeur et exportateur industriel du pays - et discute l'hypothèse de la convergence des économies coordonnées vers le modèle libéral. Elle examine d'abord les formes de coordination hors-marché qui se sont consolidées entre les élites économiques suisses au cours de la période d'après-guerre. Les stratégies d'innovation incrémentale des grandes sociétés étaient soutenues par une gouvernance marquée par la faible pression des marchés des capitaux, en raison notamment de la forte concentration de l'actionnariat, de mécanismes protectionnistes en matière d'accès au contrôle des sociétés, ainsi que d'une grande interdépendance entre banques et entreprises. Cette interdépendance apparaît dans la forte densité du réseau d'interconnexions des Conseils d'administration, où les principales banques tiennent une place centrale. Le réseau met également en relation les sociétés du secteur entre elles, ainsi qu'avec des firmes actives sur d'autres marchés, ce qui témoigne de l'irréductibilité des stratégies industrielles à une pure logique de compétition centrée sur les marchés. Les stratégies à long terme du management peuvent également s'appuyer sur un système pacifié de relations industrielles, caractérisé par l'autorégulation des acteurs privés dans le cadre d'un partenariat social de branche entre des associations aux stratégies modérées, « néocorporatistes ». Nous analysons alors l'impact de la libéralisation et de la financiarisation de l'économie suisse sur la coordination des élites économiques durant les années 1990. Nous montrons que l'affirmation des fonds d'investissement a déstabilisé le système traditionnel de gouvernance d'entreprise. Ce dernier a ainsi été marqué par l'émergence d'un marché pour le contrôle de l'entreprise -fin du «capital patient » -, la dissolution de l'interdépendance entre banques et industries et plus globalement des formes de coordination hors-marché reposant sur le réseau d'interconnexions des Conseils d'administration, ainsi que par de profondes restructurations des grandes sociétés orientées vers la création de richesse pour les actionnaires. La recherche explore alors les logiques d'interactions entre la sphère de la gouvernance d'entreprise et celle des relations industrielles, l'affirmation du capital financier faisant pression sur le partenariat social dans le sens d'une flexibilisation et déréglementation du marché du travail. Par ailleurs, nous mettons en perspective le rôle central des élites dans le changement institutionnel. Loin de subir la pression des actionnaires, les préférences d'une nouvelle élite managériale au profil financier ont convergé avec les intérêts des investisseurs dans le processus de financiarisation. Ces préférences ont également participé à l'érosion du partenariat social de branche. Du côté syndical, l'émergence -ici aussi - d'une nouvelle élite, académique et issue de la gauche politique, au cours des années 1990, a remis en cause les recettes de l'ancienne génération de syndicalistes ouvriers. La principale association du secteur a ainsi diversifié ses registres d'action en investissant la sphère politique et en relativisant la paix absolue du travail, deux stratégies activement rejetées par le syndicat au cours du régime de croissance d'après-guerre. Tout en mettant la sociologie des élites au service d'une meilleure compréhension des processus de changement institutionnel dans les capitalismes contemporains, cette recherche souligne des logiques de changement différentes dans les sphères sous revue :changement disruptif dans la gouvernance d'entreprise, incrémentai dans les relations industrielles. L'analyse s'est appuyée sur le croisement de différentes méthodes : analyse documentaire, entretiens semi-directifs, analyse du parcours et profil des élites, analyse de réseau, études de cas.

Success of a general school-based physical activity intervention on bone mineral content depends on pubertal stage but not on gender

Aims: We performed a randomised controlled trial in children of both gender and different pubertal stages to determine whether a school-based physical activity (PA) program during a full schoolyear influences bone mineral content (BMC) and whether there are differences in response for boys and girls before and during puberty. Methods: Twenty-eight 1st and 5th grade classes were cluster randomised to an intervention (INT, 16 classes, n=297) and control (CON; 12 classes, n=205) group. The intervention consisted of a multi-component PA intervention including daily physical education during a full school year. Each lesson was predetermined, included about ten minutes of jumping or strength training exercises of various intensity and was the same for all children. Measurements included anthropometry (height and weight), tanner stages (by self-assessment), PA (by accelerometry) and BMC for total body, femoral neck, total hip and lumbar spine using dualenergy X-ray absorptiometry (DXA). Bone parameters were normalized for gender and tanner stage (pre- vs. puberty). Analyses were performed by a regression model adjusted for gender, baseline height, baseline weight, baseline PA, post-intervention tanner stage, baseline BMC, and cluster. Researchers were blinded to group allocation. Children in the control group did not know about the intervention arm. Results: 217 (57%) of 380 children who initially agreed to have DXA measurements had also post-intervention DXA and PA data. Mean age of prepubertal and pubertal children at baseline was 9.0±2.1 and 11.2±0.6 years, respectively. 47/114 girls and 68/103 boys were prepubertal at the end of the intervention. Compared to CON, children in INT showed statistically significant increases in BMC of total body (adjusted z-score differences: 0.123; 95%>CI 0.035 to 0.212), femoral neck (0.155; 95%>CI 0.007 to 0.302), and lumbar spine (0.127; 95%>CI 0.026 to 0.228). Importantly, there was no gender*group, but a tanner*group interaction consistently favoring prepubertal children. Conclusions: Our findings show that a general, but stringent school-based PA intervention can improve BMC in elementary school children. Pubertal stage, but not gender seems to determine bone sensitivity to physical activity loading.

Age and gender differences in the social patterning of cardiovascular risk factors in Switzerland: the CoLaus study.

OBJECTIVES: We examined the social distribution of a comprehensive range of cardiovascular risk factors (CVRF) in a Swiss population and assessed whether socioeconomic differences varied by age and gender. METHODS: Participants were 2960 men and 3343 women aged 35-75 years from a population-based survey conducted in Lausanne, Switzerland (CoLaus study). Educational level was the indicator of socioeconomic status used in this study. Analyses were stratified by gender and age group (35-54 years; 55-75 years). RESULTS: There were large educational differences in the prevalence of CVRF such as current smoking (Δ = absolute difference in prevalence between highest and lowest educational group:15.1%/12.6% in men/women aged 35-54 years), physical inactivity (Δ = 25.3%/22.7% in men/women aged 35-54 years), overweight and obesity (Δ = 14.6%/14.8% in men/women aged 55-75 years for obesity), hypertension (Δ = 16.7%/11.4% in men/women aged 55-75 years), dyslipidemia (Δ = 2.8%/6.2% in men/women aged 35-54 years for high LDL-cholesterol) and diabetes (Δ = 6.0%/2.6% in men/women aged 55-75 years). Educational inequalities in the distribution of CVRF were larger in women than in men for alcohol consumption, obesity, hypertension and dyslipidemia (p<0.05). Relative educational inequalities in CVRF tended to be greater among the younger (35-54 years) than among the older age group (55-75 years), particularly for behavioral CVRF and abdominal obesity among men and for physiological CVRF among women (p<0.05). CONCLUSION: Large absolute differences in the prevalence of CVRF according to education categories were observed in this Swiss population. The socioeconomic gradient in CVRF tended to be larger in women and in younger persons.

L'essence relationnelle. Fonctionnement neurobiologique et relations humaines

Dans une perspective phénoménologique, le corps, les fonctions vitales, le mouvement déterminent un échange constant entre le sujet et le monde, entre soi et l'autre. La neurobiologie, de son côté, s'intéresse aux transformations biologiques liées à ces expériences, mais sa méthode est fort différente. Les auteurs proposent une réflexion sur la manière dont les découvertes de la neurobiologie interviennent pour mieux "comprendre" la dimension de la rencontre. La relation intersubjective est façonnée non seulement par les structures du fonctionnement mental, par le vécu du sujet, mais encore par la "danse" des postures et le mouvement des corps ; elle est enfin portée par le milieu culturel et social, par la nature de l'environnement. La construction des liens entre le patient et le thérapeute permet à chacun d'eux de cheminer vers un accomplissement de sa propre existence. In a phenomenological perspective, the body, the vital functions, the movements determine a constant exchange between the subject and the world, between self and the others. The neurobiology on its part, is interested in the biological transformations connected to these experiences but its method is quite different. The authors suggest to consider how the neurobiological discoveries help to get a better understanding of the dimension of the encounter. The intersubjective relationship is not only shaped by the structures of the mental functioning, by the subject's experiences, but also by the « dance » of the postures and movements of the body; it is nonetheless influenced by the cultural and social environment, as well as by the type of environment. The build-up of relationships between the therapist and the patient allows both of them to find a way to fulfillment of their own existence.

Parents' alcohol use: gender differences in the impact of household and family chores.

BACKGROUND: Social roles influence alcohol use. Nevertheless, little is known about how specific aspects of a given role, here parenthood, may influence alcohol use. The research questions for this study were the following: (i) are family-related indicators (FRI) linked to the alcohol use of mothers and fathers? and (ii) does the level of employment, i.e. full-time, part-time employment or unemployment, moderate the relationship between FRI and parental alcohol use? METHODS: Survey data of 3217 parents aged 25-50 living in Switzerland. Mean comparisons and multiple regression models of annual frequency of drinking and risky single occasion drinking, quantity per day on FRI (age of the youngest child, number of children in the household, majority of child-care/household duties). RESULTS: Protective relationships between FRI and alcohol use were observed among mothers. In contrast, among fathers, detrimental associations between FRI and alcohol use were observed. Whereas maternal responsibilities in general had a protective effect on alcohol use, the number of children had a detrimental impact on the quantity of alcohol consumed per day when mothers were in paid employment. Among fathers, the correlations between age of the youngest child, number of children and frequency of drinking was moderated by the level of paid employment. CONCLUSION: The study showed that in Switzerland, a systematic negative relationship was more often found between FRI and women's drinking than men's. Evidence was found that maternal responsibilities per se may protect from alcohol use but can turn into a detrimental triangle if mothers are additionally in paid employment.
