Genetic variants influencing circulating lipid levels and risk of coronary artery disease.

OBJECTIVE: Genetic studies might provide new insights into the biological mechanisms underlying lipid metabolism and risk of CAD. We therefore conducted a genome-wide association study to identify novel genetic determinants of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides. METHODS AND RESULTS: We combined genome-wide association data from 8 studies, comprising up to 17 723 participants with information on circulating lipid concentrations. We did independent replication studies in up to 37 774 participants from 8 populations and also in a population of Indian Asian descent. We also assessed the association between single-nucleotide polymorphisms (SNPs) at lipid loci and risk of CAD in up to 9 633 cases and 38 684 controls. We identified 4 novel genetic loci that showed reproducible associations with lipids (probability values, 1.6×10(-8) to 3.1×10(-10)). These include a potentially functional SNP in the SLC39A8 gene for HDL-C, an SNP near the MYLIP/GMPR and PPP1R3B genes for LDL-C, and at the AFF1 gene for triglycerides. SNPs showing strong statistical association with 1 or more lipid traits at the CELSR2, APOB, APOE-C1-C4-C2 cluster, LPL, ZNF259-APOA5-A4-C3-A1 cluster and TRIB1 loci were also associated with CAD risk (probability values, 1.1×10(-3) to 1.2×10(-9)). CONCLUSIONS: We have identified 4 novel loci associated with circulating lipids. We also show that in addition to those that are largely associated with LDL-C, genetic loci mainly associated with circulating triglycerides and HDL-C are also associated with risk of CAD. These findings potentially provide new insights into the biological mechanisms underlying lipid metabolism and CAD risk.

Treatment intensification and risk factor control: toward more clinically relevant quality measures.

BACKGROUND: Intensification of pharmacotherapy in persons with poorly controlled chronic conditions has been proposed as a clinically meaningful process measure of quality. OBJECTIVE: To validate measures of treatment intensification by evaluating their associations with subsequent control in hypertension, hyperlipidemia, and diabetes mellitus across 35 medical facility populations in Kaiser Permanente, Northern California. DESIGN: Hierarchical analyses of associations of improvements in facility-level treatment intensification rates from 2001 to 2003 with patient-level risk factor levels at the end of 2003. PATIENTS: Members (515,072 and 626,130; age >20 years) with hypertension, hyperlipidemia, and/or diabetes mellitus in 2001 and 2003, respectively. MEASUREMENTS: Treatment intensification for each risk factor defined as an increase in number of drug classes prescribed, of dosage for at least 1 drug, or switching to a drug from another class within 3 months of observed poor risk factor control. RESULTS: Facility-level improvements in treatment intensification rates between 2001 and 2003 were strongly associated with greater likelihood of being in control at the end of 2003 (P < or = 0.05 for each risk factor) after adjustment for patient- and facility-level covariates. Compared with facility rankings based solely on control, addition of percentages of poorly controlled patients who received treatment intensification changed 2003 rankings substantially: 14%, 51%, and 29% of the facilities changed ranks by 5 or more positions for hypertension, hyperlipidemia, and diabetes, respectively. CONCLUSIONS: Treatment intensification is tightly linked to improved control. Thus, it deserves consideration as a process measure for motivating quality improvement and possibly for measuring clinical performance.

Association of PCK1 with Body Mass Index and Other Metabolic Features in Patients With Psychotropic Treatments.

Weight gain is a major health problem among psychiatric populations. It implicates several receptors and hormones involved in energy balance and metabolism. Phosphoenolpyruvate carboxykinase 1 is a rate-controlling enzyme involved in gluconeogenesis, glyceroneogenesis and cataplerosis and has been related to obesity and diabetes phenotypes in animals and humans. The aim of this study was to investigate the association of phosphoenolpyruvate carboxykinase 1 polymorphisms with metabolic traits in psychiatric patients treated with psychotropic drugs inducing weight gain and in general population samples. One polymorphism (rs11552145G > A) significantly associated with body mass index in the psychiatric discovery sample (n = 478) was replicated in 2 other psychiatric samples (n1 = 168, n2 = 188), with AA-genotype carriers having lower body mass index as compared to G-allele carriers. Stronger associations were found among women younger than 45 years carrying AA-genotype as compared to G-allele carriers (-2.25 kg/m, n = 151, P = 0.009) and in the discovery sample (-2.20 kg/m, n = 423, P = 0.0004). In the discovery sample for which metabolic parameters were available, AA-genotype showed lower waist circumference (-6.86 cm, P = 0.008) and triglycerides levels (-5.58 mg/100 mL, P < 0.002) when compared to G-allele carriers. Finally, waist-to-hip ratio was associated with rs6070157 (proxy of rs11552145, r = 0.99) in a population-based sample (N = 123,865, P = 0.022). Our results suggest an association of rs11552145G > A polymorphism with metabolic-related traits, especially in psychiatric populations and in women younger than 45 years.

Association between smoking and recurrence of venous thromboembolism and bleeding in elderly patients with past acute venous thromboembolism.

BACKGROUND: While the association between smoking and arterial cardiovascular events has been well established, the association between smoking and venous thromboembolism (VTE) remains controversial. OBJECTIVES: To assess the association between smoking and the risk of recurrent VTE and bleeding in patients who have experienced acute VTE. PATIENTS/METHODS: This study is part of a prospective Swiss multicenter cohort that included patients aged ≥65years with acute VTE. Three groups were defined according to smoking status: never, former and current smokers. The primary outcome was the time to a first symptomatic, objectively confirmed VTE recurrence. Secondary outcomes were the time to a first major and clinically relevant non-major bleeding. Associations between smoking status and outcomes were analysed using proportional hazard models for the subdistribution of a competing risk of death. RESULTS: Among 988 analysed patients, 509 (52%) had never smoked, 403 (41%) were former smokers, and 76 (8%) current smokers. After a median follow-up of 29.6months, we observed a VTE recurrence rate of 4.9 (95% confidence interval [CI] 3.7-6.4) per 100 patient-years for never smokers, 6.6 (95% CI 5.1-8.6) for former smokers, and 5.2 (95% CI 2.6-10.5) for current smokers. Compared to never smokers, we found no association between current smoking and VTE recurrence (adjusted sub-hazard ratio [SHR] 1.05, 95% CI 0.49-2.28), major bleeding (adjusted SHR 0.59, 95% CI 0.25-1.39), and clinically relevant non-major bleeding (adjusted SHR 1.21, 95% CI 0.73-2.02). CONCLUSIONS: In this multicentre prospective cohort study, we found no association between smoking status and VTE recurrence or bleeding in elderly patients with VTE.

Antibody levels against GLURP R2, MSP1 block 2 hybrid and AS202.11 and the risk of malaria in children living in hyperendemic (Burkina Faso) and hypo-endemic (Ghana) areas.

Differences in parasite transmission intensity influence the process of acquisition of host immunity to Plasmodium falciparum malaria and ultimately, the rate of malaria related morbidity and mortality. Potential vaccines being designed to complement current intervention efforts therefore need to be evaluated against different malaria endemicity backgrounds. The associations between antibody responses to the chimeric merozoite surface protein 1 block 2 hybrid (MSP1 hybrid), glutamate-rich protein region 2 (GLURP R2) and the peptide AS202.11, and the risk of malaria were assessed in children living in malaria hyperendemic (Burkina Faso, n = 354) and hypo-endemic (Ghana, n = 209) areas. Using the same reagent lots and standardized protocols for both study sites, immunoglobulin (Ig) M, IgG and IgG sub-class levels to each antigen were measured by ELISA in plasma from the children (aged 6-72 months). Associations between antibody levels and risk of malaria were assessed using Cox regression models adjusting for covariates. There was a significant association between GLURP R2 IgG3 and reduced risk of malaria after adjusting age of children in both the Burkinabe (hazard ratio 0.82; 95 % CI 0.74-0.91, p < 0.0001) and the Ghanaian (HR 0.48; 95 % CI 0.25-0.91, p = 0.02) cohorts. MSP1 hybrid IgM was associated (HR 0.85; 95 % CI 0.73-0.98, p = 0.02) with reduced risk of malaria in Burkina Faso cohort while IgG against AS202.11 in the Ghanaian children was associated with increased risk of malaria (HR 1.29; 95 % CI 1.01-1.65, p = 0.04). These findings support further development of GLURP R2 and MSP1 block 2 hybrid, perhaps as a fusion vaccine antigen targeting malaria blood stage that can be deployed in areas of varying transmission intensity.

A qualitative study of inclusion at a residential summer camp

The purpose of this qualitative case study was to understand the inclusion process at a Project Rainbow affiliated camp. Project Rainbow is a non-profit organization which promotes inclusion into children's camps in Ontario. This study was completed in order to provide stakeholders of the camping industry insight on how inclusive techniques can be implemented in residential camps. The researcher observed one camp's inclusion techniques for six days. The researcher observed three campers with disabilities and the camp staff and campers that interacted with them on a daily basis. While the researcher was at the camp, she interviewed nine staff members. The staff members consisted of the camp director, the inclusion coordinator, four camp counsellors, and three inclusion counsellors. An additional interview was conducted after arriving home from camp with the manager from Project Rainbow. The qualitative analysis program NVivo was used to help organize the analyzed data. The researcher found that in attempting to build a culture of inclusion, two important concepts are necessary. First, mutual leadership involved the camp director and Project Rainbow working together as a team to facilitate the inclusion process. Second, power of supportive relationships focused on inclusion being the responsibility of everyone, teamwork, and creating a welcoming environment. Hints at some potentially serious problems related to staff training, teamwork, and attitudes of non-disabled campers pointed to future research and policies which focus on the Ontario and Canadian Camping Associations' role in inclusion, in addition to camp in this study and Project Rainbow.

Organizational capacity and knowledge transfer : a qualitative case study of the 2007 Canada Winter Games host society

Understanding and managing the knowledge transfer process in sport organizations is an essential component to enhance organizational capacity. Very little research on either capacity or knowledge transfer within a sport organization exists. Consequently, the purpos e of this qualitative case study was to, examine the transfer of knowledge process within a major games host society. Specifically, two research goals guided the study: 1) To develop a model to explain a knowledge t r ans f e r process in a non-profit ma jor games hos t organization and 2) To examine the relevance of the model to a Canada Games Hos t Society. Data we r e collected from interviews with middle and senior level volunteers as well as senior s t a f f members (n= 27), document s and observations. The findings indicated three barriers to knowledge transfer: structural, systemic, and cultural. As a result of the findings a revised model for knowledge transfer wa s proposed that included modifications related to the direction of knowledge flow, timing of the knowledge transfer process, and group inter-relations. Implications identified the importance of intuition managers, time and organizational levels for successful knowledge transfer. Recommendations for future host societies and the Canada Games Council are presented.

Towards a communicative understanding of organizational change : Koumbit's change process

Comment comprendre les dynamiques qui sous-tendent les changements des organisations? Le changement organisationnel fait partie de la réalité quotidienne des organisations et, comme en témoigne une vaste littérature, le sujet a été abordé à partir de diverses perspectives conceptuelles. Toutefois, plusieurs questions fondamentales demeurent quant à la façon dont le changement organisationnel est accompli (Tsoukas & Chia, 2002; Chia, 1999). Je suggère que la clé pour répondre à ces questions se trouve dans l’étude de la communication. Cependant, le rôle de la communication dans la production du changement reste peu exploré dans les conceptualisations actuelles sur le sujet. Ainsi, l’objectif principal de cette thèse est de décrire la façon dont le changement émerge dans la communication, en d’autres termes, comment il est accompli à partir des interactions. Dans cette recherche, je propose que la compréhension du changement passe par une vision de la communication comme un processus constant dans lequel les réalités sont créées, négociées et transformées de manière interactive. Cette conception est fondée sur a plurified view of interactions (Cooren, Fox, Robichaud & Talih, 2005; Cooren 2010) qui prend en considération la contribution d’êtres appartenant à diverses ontologies (e.g., ordinateurs, règlements, principes, émotions, règles, c.) dans l’action. En mobilisant cette vision de la communication, j’ai étudié les changements qui ont eu lieu à Koumbit — une organisation à but non lucratif basée à Montréal qui œuvre dans le domaine des technologies de l’information. L’observation, les entrevues ainsi que la révision de documents officiels ont été les techniques choisies pour cueillir les données. Ma recherche m’a permis de déterminer que le changement organisationnel est un processus progressif qui se matérialise d’interaction en interaction. C’est en composant et en recomposant des ensembles d’associations que se crée une différence dans l’état des choses. Si bien les interactions sont accomplies dans le ici et le maintenant, leur caractère hybride leur permet de rendre compte de ce que l’organisation a été et de ce qu’elle sera. Cette étude suggère que, d’un point de vue communicationnel, les mécanismes à partir desquels le changement organisationnel est accompli n sont pas aussi différents de ceux qui produisent les processus organisants (organizing).

Attitudes et comportements alimentaires des athlètes québécoises pratiquant un sport esthétique à un haut niveau : caractéristiques personnelles et comparaison à un groupe de contrôle

La pratique d’un sport de type esthétique est aujourd’hui considérée par plusieurs (Sundgot-Borgen & Torstveit, 2004; Thompson & Sherman, 2010) comme un facteur de risque à l’adoption d’attitudes et de comportements alimentaires inappropriés à l’égard de l’alimentation et de l’image corporelle (ACIAI) et ultimement au développement d’un trouble des conduites alimentaires (TCA). Les études actuelles portant sur cette problématique rapportent toutefois des résultats contradictoires. De plus, certains aspects méthodologiques associés notamment à l’hétérogénéité des échantillons limitent la portée interprétative de ces résultats. Afin de pallier les limites actuelles des écrits empiriques, cette thèse a pour but de tracer le portrait de la problématique des désordres alimentaires chez les jeunes athlètes québécoises de haut niveau en sport esthétique. Pour ce faire, un échantillon homogène de 145 adolescentes âgées de 12 à 19 ans a été constitué soit 52 athlètes de haut niveau et 93 non-athlètes. Les sports représentés sont le patinage artistique, la nage synchronisée et le ballet. À partir de cet échantillon, deux études sont réalisées. L’objectif de la première étude est de comparer l’intensité des ACIAI et la prévalence des TCA dans les deux groupes à l’aide de deux questionnaires soit le Eating Disorder Examination Questionnaire (EDE-Q) et le Eating Disorder Inventory-3 (EDI-3). Les résultats obtenus suggèrent qu’il n’y a pas de différence significative entre les athlètes et les non-athlètes de l’échantillon en ce qui a trait à l’intensité des ACIAI et à la prévalence des TCA. La deuxième étude est constituée de deux objectifs. Tout d’abord, comparer les deux groupes relativement aux caractéristiques personnelles suivantes : l’insatisfaction de l’image corporelle (IIC), le sentiment d’efficacité personnelle envers l’alimentation normative (SEP-AN) et l’image corporelle (SEP-IC), le perfectionnisme (P), l’ascétisme (As), la dysrégulation émotionnelle (DÉ) et le déficit intéroceptif (DI). De nature plus exploratoire, le second objectif de cette étude est de décrire et de comparer les caractéristiques personnelles qui sont associées aux ACIAI dans chacun des groupes. Afin de réaliser ces objectifs, deux autres questionnaires ont été utilisés soit le Eating Disorder Recovery Self-efficacy Questionnaire-f (EDRSQ-f) et le Body Shape Questionnaire (BSQ). En somme, les analyses indiquent que les athlètes de l’échantillon présentent des niveaux plus faibles de SEP-AN et de DÉ. Ce faisant, elles auraient moins confiance en leur capacité à maintenir une alimentation normative, mais réguleraient plus efficacement leurs émotions que les adolescentes non-athlètes. Une fois l’âge et l’indice de masse corporelle contrôlés, les résultats démontrent également que le SEP-AN et l’IIC contribuent à prédire dans chaque groupe les ACIAI tels que mesurés par la recherche de minceur. Le SEP-AN a aussi été associé dans les deux groupes à l’intensité des symptômes boulimiques. Les modèles obtenus diffèrent cependant quant aux variables prédictives principales. Chez les athlètes de l’échantillon, l’intensité des conduites boulimiques est associée à la DÉ alors qu’elle est davantage liée au DI chez les adolescentes non sportives. Enfin, en plus de discuter et de comparer l’ensemble de ces résultats aux autres travaux disponibles, les apports distinctifs de la thèse et les principales limites des études sont abordés. Des pistes sont également suggérées afin d’orienter les recherches futures et des implications cliniques sont proposées.

The role of the board in building strategic capability: towards an integrated model of sport governance research

Governance is a critical issue confronting sport organisations. Its importance in the management of sport organisations has been heightened due to the transition of many sports from predominantly volunteer administered organisations anchored in an amateur ethos, to professionally managed entities catering to a more sophisticated sport marketplace. This paper identifies four elements from the sport governance literature as the key research foci to date: shared leadership, board motivation, board roles, and board structure. Four generic themes (performance, conformance, policy and operations) are also examined and expressed as governance capabilities. The strategic role and performance of the board, while central to the practice of governance, is shown to be a weakness in many sport organisations. Further, the strategic role of the board is underdeveloped in the sport management and governance research literature. Finally, it is noted that the governance literature is shaped by a normative and prescriptive approach that may not fully encompass the diversity that exists within the sport setting. The paper concludes by identifying and affirming the critical gaps in our knowledge of sport governance. Future work should seek to understand sector-specific considerations, such as non-profit and commercial differences in sport; governance designs in response to changing environmental conditions; the impact of the CEO on the board's strategic contributions; and strategic activity by the board. More use of qualitative research methods to probe such issues is recommended

Transferring goodwill : are positive attitudes towards the event related to positive results for the sponsor?

The transfer of positive brand image from the sponsored event to the sponsor is now one of the main reasons cited for engaging in event sponsorship activity. Beyond just simple brand associations though, it has been recognised that patrons often feel "goodwill" towards certain sponsored events and these feelings could also be transferred to enhance sponsorship outcomes. This paper reports on an email survey of over 300 patrons of a non-profit Arts Festival, examining whether "goodwill" can influence sponsorship effectiveness. Specifically, the focus here is on the relationship between positive attitudes toward the event and sponsorship outcomes. The findings suggest that satisfaction with the event is correlated positively with sponsor recall but not recognition. Those with higher degrees of "goodwill" towards the event did have more positive attitudes towards the sponsor and were more likely to recall and recognise sponsors correctly.

Career planning and development in elite sport : an AFL perspective

This paper examines career development in elite sport, specifically the perceptions of Australian Football League (AFL) players on the career development programs offered by the AFL Players Association. HRM literature reveals considerable research in the area of career planning and development. There is however a paucity of research into career planning for elite athletes in Australia. While overseas studies indicate a lack of career planning by elite athletes for their life after sport, that is not the findings of this research. This pilot study reveals that AFL Players not only recognise the need for and value of career planning, they actively utilise the AFL Players Association, Player Development program, in particular the training and development and guidance aspects of the program, This research is useful because it provides feedback to those who formulate such programs to better cater for and create more focused programs. It also provides the basis for further research across the sport and the potential to test its applicability across other elite sports.
