No evidence of association between prothrombotic gene polymorphisms and the development of acute myocardial infarction at a young age
Background : we investigated the association between 9 polymorphisms of genes encoding hemostasis factors and
myocardial infarction in a large sample of young patients chosen because they have less coronary atherosclerosis than
older patients, and thus their disease is more likely to be related to a genetic predisposition to a prothrombotic state Methods and Results : this nationwide case-control study involved 1210 patients who had survived a first myocardial infarction at an age of 45 years who underwent coronary arteriography in 125 coronary care units and 1210 healthy subjects matched for age, sex, and geographical origin. None of the 9 polymorphisms of genes encoding proteins involved in coagulation (G-455A -fibrinogen: OR, 1.0; CI, 0.8 to 1.2; G1691A factor V: OR, 1.1; CI, 0.6 to 2.1; G20210A factor II: OR, 1.0; CI, 0.5 to 1.9; and G10976A factor VII: OR, 1.0; CI, 0.8 to 1.3), platelet function (C807T
glycoprotein Ia: OR, 1.1; CI, 0.9 to 1.3; and C1565T glycoprotein IIIa: OR, 0.9; CI, 0.8 to 1.2), fibrinolysis (G185T factor XIII: OR, 1.2; CI, 0.9 to 1.6; and 4G/5G plasminogen activator inhibitor type 1: OR, 0.9; CI, 0.7 to 1.2), or homocysteine metabolism (C677T methylenetetrahydrofolate reductase: OR, 0.9; CI, 0.8 to 1.1) were associated with an increased or decreased risk of myocardial infarction Conclusions : this study provides no evidence supporting an association between 9 polymorphisms of genes encoding proteins involved in hemostasis and the occurrence of premature myocardial infarction or protection against it
The altruism of pre-adolescent children's perspectives on 'worry' and 'happiness' in Australia and England
This article presents the perspectives of Australian and English children on the broad terms worry, happy and change. Utilizing a qualitative methodology, the study engaged with pre-adolescent children (‘tweens’) on the issues affecting them in the modern world. Participants were drawn from a large regional secondary school in Eastern Australia and a comparable regional secondary school in England. Students completed an open-ended questionnaire. In both contexts, many of the children identified specific personal and predominantly social priorities. In their responses, the children tended towards features in their lives that reflected the high importance of individual relationships. The factors that give rise to the identified importance of the family relationship reveal their prioritization of the conditions in their lifeworld. The children demonstrated an acute and sophisticated knowledge of their local community and the global world.They identified local and global issues as they impacted on them personally
