Efficacy of intervention at traffic schools reducing impulsive action, and association with candidate gene variants

Road traffic injuries are the leading cause of death among young people. Recognising the role of impulsive tendencies in risk taking behaviour may help novice drivers to behave more safely. Previously, a brief intervention focusing on impulsive traffic behaviour, conducted by psychologists in driving schools, has been effective [1, 2]. Following the success a new intervention study was carried out but this time the intervention was conducted by regular driving school teachers, who had previously been trained to carry out the intervention. The new intervention, similarly to the previous one, significantly decreased prevalence of traffic collisions and lowered general traffic risk (occurrence of either a recorded traffic offence or a collision). The association of impulsivity measures and candidate gene variants with risk-taking behaviour in traffic and the efficacy of the intervention is also analysed and discussed in the study.

Every two years ITMA elects a country to host its congress. In 2018, Brazil hosted PhDs and researchers from more than ten countries (including United States, Japan, Canada, Sweden, China, Estonia, Argentina, Costa Rica, German and Brazil) in order to discuss about traffic in a global scope. The 26th ITMA World Congress organized by INAQ, was held at Pontifícia Universidade Católica do Paraná – PUCPR, in Curitiba, from October 30 to November 1.The congress debated issues on medical specialties and other fields of expertise such as Psychology, Engineer, Law, Road Safety, Education and Public Administration, aiming to find measures to decrease the number of deaths and consequences of road accidents.

The organization of the 26th ITMA CONGRESS had the Company INAQ – AVALIAÇÃO E GESTÃO DE QUALIDADE (INAQ – Quality Assessment and Management) of the city of Curitiba, Brazil.

Donald Redelmeier Found Full Moon is Associated with Fatal Motorcycle Crashes

Donald Redelmeier Found Full Moon is Associated with Fatal Motorcycle Crashes

ITMA’s Regional Director in North America, Dr. Donald Redelmeier recently published his work on BMJ to describe the relationship between the full moon and an increased risk of fatal motorcycle crashes. Although other potential confounders cannot be excluded from this relationship, it is worthy to be aware that motorcyclists are facing a higher risk of fatal crashes during a full moon. It is encouraged to ride with extra care under such a circumstance and appreciate the power of seemingly minor distractions at all times.

Following specific strategies were proposed for physicians to help their patients to prevent drunk driving.

  • Alcohol screening and brief interventions for patients with alcohol problems
  • Physician warnings for patients who sometimes drink and drive
  • Treatment of patients diagnosed with alcohol dependence
  • Counseling of patients not to ride with drunk drivers
  • Supporting enforcement of laws against drunk driving
