Abstract: In this paper, I compare several readily observable measures of intellectual property rights between agricultural economics-a discipline that attaches considerable importance to author order-and economics-a discipline that attaches little, if any, importance to author order. Specifically, I examine: (1) the incidence of coauthorship-i.e., the likelihood that an individual coauthors with others, (2) the extent of coauthorship-i.e., the number of authors listed on each coauthored paper, (3) the number of individuals thanked for contributing to the research being reported and (4) alphabetization of authorship for papers published in three top journals in each scientific discipline. I find statistically significant differences across-the-board. These differences suggest that interdisciplinary differences with respect to the relative importance attached to contribution affect the allocation of intellectual property rights in science. These findings are compelling because they demonstrate that the allocation of intellectual property rights and how the production of science is structured are related. (C) 2002 Elsevier Science B.V.

Abstract: A survey of 120 557 married, female, registered U.S. nurses, aged 30 to 55 years, carried out in 1976, showed that 38 459 (31·9%) had at some time used hair dyes, and 3548 (2·9%) had had cancer. For all cancers combined, the risk ratio (R.R.) for the development of cancer among women who had used hair dyes at any time, compared with those who had never used them, was 1·10 (P=0·02). When cancers were subdivided by anatomical site into 16 main groups, only those of the cervix uteri (R.R.=1·44, P<0·001) and those of the vagina and vulva (R.R.=2·58, P=0·02) showed statistically significant associations with use of permanent hair dyes. Both these associations were reduced but remained significant after standardisation for cigarette smoking, and neither showed increases in risk of cancer with increasing years since first use of hair dyes. Women who had used permanent dyes for 21 years or more before the onset of cancer had a significant increase in risk for all sites combined (R.R.=1·38, P=0·02), compared with “never users”. This increase was primarily due to an excess number of observed to expected cases of breast cancer (24 versus 16·3). However, among those who had first used dye 16 to 20 years before diagnosis of breast cancer, there was an almost equal deficit in numbers of cancers at this site (16 observed versus 25·1 expected). The present evidence does not indicate that any material risk of cancer is likely to have occurred during the initial 20 years following first use of permanent hair dyes.

Abstract: A controlled trial of long term domiciliary oxygen therapy has been carried out in three centres in the U.K. The 87 patients, all under 70 years of age, who took part had chronic bronchitis or emphysema with irreversible airways obstruction, severe arterial hypoxaemia, carbon dioxide retention, and a history of congestive heart failure. The patients were randomised to oxygen therapy (treated) or no oxygen (controls). Oxygen was given by nasal prongs for at least 15 h daily, usually at 2 1/min. The two groups were well matched, both clinically and in terms of lung function and other laboratory findings. 19 of the 42 oxygen treated patients died in the five years of survival follow-up compared with 30 out of 45 controls: in the 66 men in this trial the survival advantage of oxygen did not emerge until 500 days had elapsed. Survival for the 12 female controls was surprisingly poor, 8 of them being dead at 3 years. Mortality was not easy to predict, though a summation of arterial carbon dioxide tension and red cell mass was helpful. Neither time spent in hospital because of exacerbations of respiratory failure nor work attendance were affected by oxygen therapy, but these patients were very ill at the start of the trial and many had already retired on grounds of age or illhealth. Physiological measurements suggested that oxygen did not slow the progress of respiratory failure in those who died early. However, in longer term survivors on oxygen, arterial oxygenation did seem to stop deterioration.

Abstract: A prospective general population study of 22707 Chinese men in Taiwan has shown that the incidence of primary hepatocellular carcinoma(PHC) among carriers of hepatitis B surface antigen (HBsAg)is much higher than among non-carriers (1158/100000 vs5/100000 during 75000 man-years of follow-up). The relative risk is 223. PHC and cirrhosis accounted for 54· 3%of the 105 deaths among HBsAg carriers but accounted for only 1.5% of the 202 deaths among non-carriers. These findings support the hypothesis that hepatitis B virus has aprimary role in the aetiology of PHC.

Abstract: Biopsy specimens were taken from intact areas of antral mucosa in 100 consecutive consenting patients presenting for gastroscopy. Spiral or curved bacilli were demonstrated in specimens from 58 patients. Bacilli cultured from 11 of these biopsies were gram-negative, flagellate, and microaerophilic and appeared to be a new species related to the genus Campylobacter. The bacteria were present in almost all patients with active chronic gastritis, duodenal ulcer, or gastric ulcer and thus may be an important factor in the aetiology of these diseases.

Full Text: L\Lancet328, 881.pdf

Abstract: The hypothesis that homoeopathic potencies are placebos was tested in a randomised, double-blind, placebo-controlled trial. The study model chosen compared the effects of a homoeopathic preparation of mixed grass pollens with placebo in 144 patients with active hayfever. The homoeopathically treated patients showed a significant reduction in patient and doctor assessed symptom scores. The significance of this response was increased when results were corrected for pollen count and the response was associated with a halving of the need for antihistamines. An initial aggravation of symptoms was noted more often in patients receiving the potency and was followed by an improvement in that group. No evidence emerged to support the idea that placebo action fully explains the clinical responses to homoeopathic drugs.

Abstract: The effect of blood-lead on children’s ability and attainment was investigated in a sample of 855 boys and girls aged 6-9 years from eighteen primary schools within a defined area of central Edinburgh. The geometric mean blood-lead value was 10.4 μg/dl. In a stratified subsample, 501 children completed individual tests of cognitive ability and educational attainment from the British Ability Scales (BAS). An extensive home interview with a parent was also done. Multiple regression analyses showed a significant negative relation between log blood-lead and BAS combined score, number skills, and word reading when thirty-three possible confounding variables were taken into account. There was a dose-response relation between blood-lead and test scores, with no evidence of a threshold. The size of the effect was small compared with that of other factors. Lead at low levels of exposure probably has a small harmful effect on the performance of children in ability and attainment tests.

Abstract: In a retrospective survey, 487 research projects approved by the Central Oxford Research Ethics Committee between 1984 and 1987, were studied for evidence of publication bias. As of May, 1990, 285 of the studies had been analysed by the investigators, and 52% of these had been published. Studies with statistically significant results were more likely to be published than those finding no difference between the study groups (adjusted odds ratio [OR] 2.32; 95% confidence interval [Cl] 1.25-4.28). Studies with significant results were also more likely to lead to a greater number of publications and presentations and to be published in journals with a high citation impact factor. An increased likelihood of publication was also associated with a high rating by the investigator of the importance of the study results, and with increasing sample size. The tendency towards publication bias was greater with observational and laboratory-based experimental studies (OR = 3.79; 95% Cl = 1.47-9.76) than with randomised clinical trials (OR = 0.84; 95% Cl = 0.34-2.09). We have confirmed the presence of publication bias in a cohort of clinical research studies. These findings suggest that conclusions based only on a review of published data should be interpreted cautiously, especially for observational studies. Improved strategies are needed to identify the results of unpublished as well as published studies.

Abstract: It is suspected that diet influences the risk of getting breast cancer. A study of diet and breast cancer was done among 200 Singapore Chinese women with histologically confirmed disease and 420 matched controls. A quantitative food-frequency questionnaire was used to assess intakes of selected nutrients and foods 1 year before interview. Daily intakes were computed and risk analysed after adjustment for concomitant risk factors.

In premenopausal women, high intakes of animal proteins and red meat were associated with increased risk. Decreased risk was associated with high intakes of polyunsaturated fatty acids (PUFA), beta-carotene, soya proteins, total soya products, a high PUFA to saturated fatty acid ratio, and a high proportion of soya to total protein. In multiple analysis, the variables which were significant after adjustment for each other were red meat (p < 0.001) as a predisposing factor, and PUFA (p = 0.02), beta-carotene (p = 0.003), and soya protein (p = 0.02) as protective factors. The analysis of dietary variables in postmenopausal women gave uniformly non-significant results.

Our finding that soya products may protect against breast cancer in younger women is of interest since these foods are rich in phyto-oestrogens.
