Multicenter Study Clinical Trial
16-year mortality from breast cancer in the UK Trial of Early Detection of Breast Cancer.
The UK Trial of Early Detection of Breast Cancer (TEDBC) is a non-randomised study, which was set up in 1979 to investigate the effect of screening and education about breast self-examination on breast-cancer mortality. We report mortality results after 16 years of follow-up, including results by age at trial entry. ⋯ The results from TEDBC support those from randomised trials in Edinburgh and elsewhere, and show that a reduction in breast-cancer mortality resulting from screening can be achieved in the UK. There was no evidence of less benefit in women aged 45-46 years at the start of screening; the effect of screening in this age-group begins to emerge after 3-4 years.

Severely malnourished children have high mortality rates. Death commonly occurs during the first 48 h after hospital admission, and has been attributed to faulty case-management. We developed a standardised protocol for acute-phase treatment of children with severe malnutrition and diarrhoea, with the aim of reducing mortality. ⋯ Compared with non-protocol management, our standardised protocol resulted in fewer episodes of hypoglycaemia, less need for intravenous fluids, and a 47% reduction in mortality. This standardised protocol should be considered in all children with diarrhoea and severe malnutrition.

Randomized Controlled Trial Multicenter Study Clinical Trial
14 years of follow-up from the Edinburgh randomised trial of breast-cancer screening.
The Edinburgh randomised trial of breast-cancer screening recruited women aged 45-64 years from 1978 to 1981 (cohort 1), and those aged 45-49 years during 1982-85 (cohorts 2 and 3). Results based on 14 years of follow-up and 270,000 woman-years of observation are reported. ⋯ Our findings confirm results from randomised trials in Sweden and the USA that screening for breast cancer lowers breast-cancer mortality. Similar results are reported by the UK geographical comparison, UK Trial of Early Detection of Breast Cancer. The results for younger women suggest benefit from introduction of screening before 50 years of age.
