摘要:

SummaryA rationale is presented for estimating the optimal number of CT† head scanners in a defined population. It is derived from calculations of the appropriate number of scans likely to be generated by the clinical indications for scanning. These indications assume that competent specialist assessment of the patients prior to scanning has occured.The indications for head scanner use on present practice are cases of intracranial injury, intracerebral and sub‐arachnoid haemorrhage, epilepsy, dementia, intracranial neoplasm, hydrocephalus and other less common conditions under specified conditions. It is estimated that 2,690 – 2,830 scans per million of population will be generated annually and that one scanner could service this, with a realistic throughput of pat

摘要:

AbstractThis paper develops the notion that environmental safety standards for human populations should be based on epidemiological data, and reviews some powerful statistical procedures which have been developed recently for this purpose. It then considers some of the limitations of epidemiological data and the ability of these new techniques to overcome them. To the extent that these limitations are inherent in the data and unmeasurable, conservative “safety factors” must be applied to the recommendations arrived at by any technique, but this uncertainty is no justification for using less than the best available analytical techniq

摘要:

SummaryA randomised controlled trial of the effects of two different physical activity programmes on coronary heart disease (CHD) risk factors, academic performance, and classroom behaviour, was conducted on over 500 children (mean age 10) in eight Adelaide primary schools in 1978. During a fourteen‐week intervention period classes were involved in either: an endurance fitness programme, a skills programme, or participated as controls. The Fitness group experienced significant gains in physical work capacity and decreases in body fat compared to the Control and Skill groups. Diastolic blood pressure decreased significantly more in the Skill group than in the Control; but no significant difference was observed between the Fitness and Control groups. Changes in the other CHD risk factors measured, systolic blood pressure, plasma cholesterol, triglycerides and HDL cholesterol did not differ between groups. Both the Fitness and Skill groups demonstrated improvements in classroom behaviour compared to the control group; but no differences in academic performance were observe
