Carlton, Victoria, AustraliaCancer risk in 680 000 people exposed to computed tomography scans in childhood or adolescence: data linkage study of 11 million AustraliansMedicalResearch.com: What are the main findings of the study?Prof Mathews:We found that for persons having at least one CT scan before the age of 20 years, and followed for an average period of 10 years, the average risk of cancer was increased by 24% compared with unexposed persons matched for age, sex and year of birth. The cancer risk increased by 16% for each CT scan that preceded the cancer by more than one year. The proportional increase in risk was greater for persons exposed at younger ages.
MedicalResearch.com: What are the main findings of the study?Dr. Franco:Population wide weight loss of about 5 kg was related with large decreases in diabetes and cardiovascular mortality. On the contrary, Body weight regain was related with an increase in diabetes prevalence, incidence, and mortality, as well as a deceleration in the previously declining rates of cardiovascular death.

Medical Research.com: What are the main findings of the study?Dr. Nordström: We have found that low cognitive function and factors related to low socioeconomic status and intoxications are strong independent risk factors for mild traumatic brain injury in men.
Medical Research.com: Were any of the findings unexpected?Dr. Nordström: Our knowledge of risk factors that predispose people to sustaining such injury is limited. Previous research has inferred that mild traumatic brain injuries have important long-term consequences on cognitive function. However, we found similar deficits in cognitive function in subjects that sustained a mild traumatic brain injury before and after cognitive testing. Thus our data suggest that the injury itself may not reduce cognitive function.
