Screening for hepatitis C virus (HCV) is recommended in patients born between 1945 and 1965 ("baby boomers") in the United States. Because these patients are often screened for colorectal cancer, dual screening for HCV may enhance case identification. Our objectives were to assess the acceptability and yield of screening for HCV among patients undergoing screening for colorectal cancer. ⋯ Acceptance of screening for HCV is high among patients undergoing screening for colorectal cancer in the Calgary area. However, the low prevalence of HCV suggests that the cost-effectiveness of birth-cohort screening in this population warrants evaluation.

Minimally invasive surgery for discectomy may accelerate recovery and reduce pain, but it also requires technical expertise and is associated with increased risks. We performed a meta-analysis to determine the effects of minimally invasive versus open surgery on functional outcomes, pain, complications and reoperations among patients undergoing cervical or lumbar discectomy. ⋯ Current evidence does not support the routine use of minimally invasive surgery for cervical or lumbar discectomy. Well-designed trials are needed given the lack of high-quality evidence.

Obesity is a major public health issue. This review updates the evidence on the effectiveness of behavioural and pharmacologic treatments for overweight and obesity in adults. ⋯ PROSPERO no. CRD42012002753.

Care in a trauma centre is associated with significant reductions in mortality after severe injury. However, emerging evidence suggests that outcomes across similarly accredited trauma centres are not equivalent, even after adjusting for case-mix. The primary objective of this analysis was to evaluate secular trends in overall mortality at trauma centres. Secondarily, we explored trauma centre-specific mortality to determine the extent of variation between centres. ⋯ We observed a significant improvement over time in the mortality of severely injured patients cared for at Ontario's trauma centres. However, considerable differences in trauma centre-specific mortality were observed. Differences were most pronounced among older injured patients and those with isolated traumatic brain injury. System-wide performance improvement initiatives should target these subgroups.

Health care providers have shown considerable interest in using information technologies such as email, text messages and video conferencing to facilitate the management of chronic noncommunicable diseases such as hypertension, diabetes mellitus and vascular disease. We sought to determine whether these technologies are available and appealing to the target population. ⋯ Many people were interested in using electronic technologies, especially video conferencing and email-based methods, to help manage their chronic condition. The effectiveness and cost implications of using email and video conferencing in the management of chronic disease deserve further consideration.
