Comparison of molecular markers expression in vacuum-assisted biopsies and surgical specimens of human breast carcinomas

In this study, we examined whether vacuum-assisted breast biopsy (VABB) specimens provide an accurate immunohistochemical assessment of estrogen receptors (ER), progesterone receptors (PR), c-erbB-2, and p53 proteins.     

The costs of traumatic brain injury due to motorcycle accidents in Hanoi, Vietnam

Background

Road traffic accidents are the leading cause of fatal and non-fatal injuries in Vietnam. The purpose of this study is to estimate the costs, in the first year post-injury, of non-fatal traumatic brain injury (TBI) in motorcycle users not wearing helmets in Hanoi, Vietnam. The costs are calculated from the perspective of the injured patients and their families, and include quantification of direct, indirect and intangible costs, using years lost due to disability as a proxy.

Methods

The study was a retrospective cross-sectional study. Data on treatment and rehabilitation costs, employment and support were obtained from patients and their families using a structured questionnaire and The European Quality of Life instrument (EQ6D).

Results

Thirty-five patients and their families were interviewed. On average, patients with severe, moderate and minor TBI incurred direct costs at USD 2,365, USD 1,390 and USD 849, with time lost for normal activities averaging 54 weeks, 26 weeks and 17 weeks and years lived with disability (YLD) of 0.46, 0.25 and 0.15 year, respectively.

Conclusion

All three component costs of TBI were high; the direct cost accounted for the largest proportion, with costs rising with the severity of TBI. The results suggest that the burden of TBI can be catastrophic for families because of high direct costs, significant time off work for patients and caregivers, and impact on health-related quality of life. Further research is warranted to explore the actual social and economic benefits of mandatory helmet use.     

A network meta-analysis of randomized controlled trials comparing treatment modalities for de novo superficial femoral artery occlusive lesions

Background

Treatment of superficial femoral artery (SFA) lesions remains challenging. We conducted a network meta-analysis of randomized controlled trials aiming to explore the efficacy of treatment modalities for SFA “de novo” lesions.
