Betting Practices Among Players in Portuguese Championships: From Cultural to Illegal Behaviours.

The growth of the online sports betting market has generated new risk areas and threats to sport integrity, such as match-fixing. In recent years, institutional concern to fight against the phenomenon has been intensified and a set of countermeasures has been adopted. One of the most widely implemented measures to protect integrity in sport is to ban athletes and sports players from betting on the competitions in which they are involved. In some countries, such as Portugal, this practice has become a crime under the new legislation. Despite the legal and sporting restrictions and the prevention programmes carried out for sport institutions to explain the gambling rules, there are many athletes who are putting bets on their own competitions and even in their own games. Through interviews with key informant actors and ethnographic fieldwork, this article describes betting patterns among sports actors in Portugal and explains the perceptions and incentives that lead them to bet in their own sports, competitions and games. The results show different conceptions of integrity between the normative discourse on legal and sport governance institutions and sports actors' opinion, essentially, the premise that suggest a direct link between betting on one's own games and manipulation of these games. In some cases, betting in one's own games helps to strengthen fair play values. However, the spreading of online betting, together with the perception of inefficient controls in the implementation of sporting and legal regulations, creates opportunity structures for fixing matches and taking financial profit though gambling activities.

Fator V de Leiden na doença de Legg-Calvé-Perthes / Leiden's V-factor in Legg-Calvé-Perthes disease

Trobofilias hereditárias têm sido implicadas na patogênese da doenca de Legg-Calvé-Perthes. Uma investigação do fator de risco hereditário mais comum para hipercoagulabilidade - a mutação no gene do fator V (fator V de Leiden) - foi conduzida em 20 pacientes com Legg-Calvé-Perthes e 214 controles sadios. A prevalência do fator V de Leiden foi maior nos pacientes com Legg-Calvé-Perthes que no grupo controle (30 vs. 1,87 por cento). A razão de chances (odds ratio) para o desenvolvimento de Legg-Calvé-Perthes foi de 22,5 (p<0,05; intervalo de confiança: 5,68- 89.07). Estes dados sugerem, o fator V de Leiden como fator de risco hereditário para hipercoagulabilidade associada ao desenvolvimento da doença de Legg-Calvé-Perthes.

Inherited tendency to hypercoagulability has been suggested as a cause of vascular thrombosis resulting in Legg-Calvé-Perthes disease. An investigation of the most common inherited risk factor for hypercoagulability - the mutation in the V-factor gene (Leiden's V-factor) - was carried out among 20 Patients diagnosed with Legg- Calvé-Perthes disease. Patients were compared with 214 healthy controls. The prevalence of the Leiden's V-factor was higher in patients with Legg-Calvé-Perthes disease than in controls (30 percent vs. 1,87 percent). The odds ratio for the development of Legg-Calvé-Perthes disease in the presence of the Leiden's V-factor mutation was 22,5 (p<0,05; confidence interval: 5,68-89.07). These data suggest the Leiden's V-factor as an inherited risk factor for hypercoagulability associated with the development of Legg-Calvé-Perthes disease.
