Abstract
Few contemporary data support the assertion that eyewitnesses are important in police investigations. In the present study, 159 UK police officers were surveyed regarding their perceptions of eyewitnesses and eyewitness performance. The respondents indicated that eyewitnesses usually provide the central leads in criminal investigations; however, the police officers also believed that eyewitnesses rarely provide sufficient information, especially descriptive details as opposed to action details. Nevertheless, the officers believed that eyewitnesses are rarely incorrect. A sizable minority reported that witnesses rarely come forward to the police and that those who do are often reluctant to testify in court. Many officers indicated that they do not have enough time to conduct good eyewitness interviews.

Abstract
OBJECTIVE To assess, using a computerised model, the effects on mortality of the use of combined oral contraceptives (COCs). DESIGN Two hypothetical cohorts of one million women each, identical except for their use of contraception. The impact of COC use was explored by applying, to each cohort, death rates which were adjusted according to a series of assumptions about the risks associated with COC use. The model also explored the effects of a number of different patterns of COC use. SETTINGS AND SUBJECTS Women aged 16, followed through to ages 50 and 75, exposed to 1994 UK death rates. MAIN OUTCOME MEASURES Numbers of deaths from various cancers and cardiovascular diseases attributable to COC use. RESULTS Based on the standard pattern of use, there were 1.7 per cent more deaths in the COC cohort to age 50. The important effects on mortality of different patterns of use and of different assumptions about risks in ex-users were illustrated. CONCLUSIONS The results confirm the findings of earlier work and provide some reassurance about the likely adverse effects of COC use.

Abstract
OBJECTIVES To evaluate the effect of purchaser mix, market competition, and trust status on hospital productivity within the NHS internal market. METHODS Hospital cost and activity data were taken from routinely collected data for acute NHS hospitals in England for 1991-2 to 1993-4. Cross sectional and longitudinal regression methods were used to estimate the effect of trust status, competition, and purchaser mix on average hospital costs per inpatient, after adjusting for outpatient activity levels, casemix, teaching activity, regional salary variation, hospital size, scale of activity, and scope of cases treated. RESULTS Real productivity gains were apparent across the study period for NHS hospitals on average. Casemix adjustment drastically improved cross sectional comparisons between hospitals. Gaining trust status and increasing host district purchaser share were associated with productivity increases after adjustment for casemix, regional salary differences, and hospital size and scope. Hospitals that became trusts during the study period were on average less productive at the beginning of the period than those that did not, and there were no significant productivity differences between trust waves at the end of the period in 1993-4. Market concentration was not associated with productivity differences. CONCLUSION Further analysis is needed to determine whether overall and trust associated productivity gains are transient effects, one off shifts, or self perpetuating reorientations of organisational behaviour. Hospitals may have chosen to become trusts because they anticipated being able to increase productivity. Increases in the proportions of small purchasers were associated with increasing costs. Importantly, this study could not adjust for changes in the quality of care.

Abstract
For people with insulin-dependent diabetes mellitus (IDDM) renal disease represents a life-threatening and costly complication. The EURODIAB IDDM Complications Study, a cross-sectional, clinic-based study, was designed to determine the prevalence of renal complications and putative risk factors in stratified samples of European individuals with IDDM. The present study examined the relationship between dietary protein intake and urinary albumin excretion rate (AER). Food intake was assessed centrally by a standardized 3-day dietary record. Urinary AER was determined in a central laboratory from a timed 24-h urine collection. Complete data were available from 2696 persons with IDDM from 30 centres in 16 European countries. In individuals who reported protein consumption less than 20% of total food energy intake, mean AER was below 20 microg/min. In those in whom protein intake constituted more than 20%, mean AER increased, a trend particularly pronounced in individuals with hypertension and/or poor metabolic control. Trends reached statistical significance for intakes of total protein (% of energy, p = 0.01) and animal protein (% of energy, p = 0.02), while no association was seen for vegetable protein (p = 0.83). These findings support the current recommendation for people with diabetes not to exceed a protein intake of 20% of total energy. Monitoring and adjustment of dietary protein appears particularly desirable for individuals with AER exceeding 20 microg/min (approximately 30 mg/24h), especially when arterial pressure is raised and/or diabetic control is poor.

Abstract
We have determined the role of cholesteryl ester transfer protein (CETP) in selective uptake of high density lipoprotein (HDL)-derived cholesteryl esters (CE) by human adipose tissue, using organ culture or collagenase-digested adipocytes. Incubation of the fresh tissue fragments with HDL containing [3H]CE or 125I-apoprotein (apo) A-I resulted in significant uptake of HDL-CE-derived label. Addition of recombinant CETP (rCETP) increased CE uptake in a dose-response fashion. In contrast, little association of 125I-apoA-I with adipose tissue was noted, and addition of rCETP did not alter apoA-I uptake or degradation. Incubation of adipose tissue with TP2, an anti-CETP monoclonal antibody, which inhibits neutral lipid transfer, markedly reduced selective uptake of HDL-CE. Studies using human adipocytes isolated by collagenase digestion also demonstrated selective uptake of HDL-CE and enhancement of this process by rCETP. To confirm that the association of HDL-CE-derived radioactivity with adipose tissue was not due to neutral lipid exchange between adipocytes and HDL, we measured changes in HDL composition following incubation of HDL and rCETP with isolated adipocytes. A decrease in HDL-CE concentration in the medium was observed, an effect which was markedly attenuated when incubations were carried out in the presence of monoclonal antibody TP2. Furthermore, the decrease in HDL-CE was accompanied by an increase in HDL free cholesterol, likely representing efflux of adipocyte cholesterol to HDL. There were no significant changes in phospholipid, apoA-I, or apoA-II in the medium following incubation with adipocytes. These data demonstrate a novel and important role for CETP in selective uptake of HDL-cholesteryl esters by human adipocytes and suggest that this pathway may be of quantitative physiological significance in HDL remodeling and adipocyte cholesterol accumulation.

Abstract
The plasma cholesteryl ester transfer protein (CETP) promotes the removal of HDL cholesteryl esters and is thought to stimulate reverse cholesterol transport (RCT). However, mechanisms by which CETP may stimulate RCT are poorly understood. Thus, we examined the relationship between plasma CETP expression and plasma cholesteryl ester formation in CETP transgenic (Tg) mice, hamsters, and human subjects with genetic CETP deficiency. Incubation of CETP Tg mouse plasma showed a 20% to 40% increase in plasma cholesterol esterification rate (CER, P < .05) compared with control mice. Injection of a neutralizing CETP monoclonal antibody (MAb) (TP2) into natural flanking region CETP Tg mice resulted in an increase in plasma free cholesterol (FC) concentration, FC/CE ratio, FC/phosphatidylcholine ratio, and hepatic CETP mRNA. In hamsters, CETP inhibition also resulted in an increase in plasma FC/phosphatidylcholine ratio and increased CETP mRNA in adipose tissue. In humans with two common CETP gene mutations (an intron 14 splicing defect and a D442G missense mutation), mean plasma CERs were 39 and 60, respectively, compared with 89 nmol x mL-1 x h-1 in normal subjects. By contrast, lecithin:cholesterol acyltransferase (LCAT) mass was normal in CETP-deficient subjects. MAb neutralization of CETP activity in incubated human plasma did not alter the LCAT reaction, even after supplementation with discoidal HDL and VLDL. Thus, genetic alterations in CETP levels lead to secondary changes in the plasma LCAT reaction, possibly because of remodeling of HDL by CETP acting in concert with other factors in vivo. In human genetic CETP deficiency, a moderate impairment in the plasma LCAT reaction may contribute to a defect in RCT, providing a potential mechanism to explain the recently observed excess of coronary heart disease in these subjects.

Abstract
We investigated the association of Dupuytren’s contracture with smoking and with alcohol by a case-control study in which 222 patients having an operation for this condition were matched for age, operation date and gender with control patients having other orthopaedic operations. Fifty of the cases were also each matched with four community controls. Data were collected by postal questionnaire. Dupuytren’s contracture needing operation was strongly associated with current cigarette smoking (adjusted odds ratio 2.8 (95% confidence interval (CI) 1.5 to 5.2)). The mean lifetime cigarette consumption was 16.7 pack-years for the cases compared with 12.0 pack-years for the controls (p = 0.016). Dupuytren’s contracture was also associated with an Alcohol Use Disorders Test score greater than 7 (adjusted odds ratio 1.9 (95% CI 1.02 to 3.57)). Mean weekly alcohol consumption was 7.3 units for cases and 5.4 units for controls (p = 0.016). The excess risk associated with alcohol did not appear to be due to a confounding effect of smoking, or vice versa. Smoking increases the risk of developing Dupuytren’s contracture and may contribute to its prevalence in alcoholics, who tend to smoke heavily.

Abstract
The relationship between individuals' choice of abstinence or moderate drinking during outpatient behavioral management treatment and outcome over 12 months' posttreatment was examined. At the initial assessment, 46% of 106 chronic alcoholic subjects chose abstinence, 44% chose moderate drinking, and 9% were unsure. Over the course of treatment, subjects were more likely to move from moderation to abstinence goals, and after the first 4 weeks of treatment, two-thirds chose abstinence. These subjects were older, had more severe alcohol problems (i.e., higher MAST scores), and were more likely to maintain their weekly alcohol consumption goals during the 16-week treatment period. Moreover, these subjects reported less alcohol use in the 12 month follow-up period, and a greater proportion were judged as having successful outcomes. The implications of these findings are discussed.

Abstract
OBJECTIVES Repeatability of a dietary method is important in determining the quality of nutritional data. It should be assessed in the population of interest. This study evaluated the repeatability of nutritional data from standardized three-day dietary records, from the clinic-based, cross-sectional multi-centre EURODIAB IDDM Complications Study. DESIGN AND SUBJECTS 15% of the total EURODIAB cohort was randomly selected to test the repeatability of nutritional intake data. Two three-day records, completed three weeks apart, were available for 216 diabetic patients (7.5%) representative of the total cohort. All records were analysed centrally, for intakes of protein (animal and vegetable), fat (saturated fat and cholesterol), carbohydrate, fibre, alcohol and energy. Repeatability was measured comparing mean intakes, determining the proportion of patients classified into the same/opposite quartile by the two three-day records and assessing mean differences with standard deviations (s.d.d). RESULTS There were no significant differences in mean energy and nutrient intakes between the first and second records. Classification of individuals into the opposite quartile occurred only in 0-4% of patients and overall about 50% (range 44-74%) of the subjects were classified into the same quartiles of intakes. Only small mean differences were found for energy intake (-156 (1633) kJ; 95% confidence limits -375, 63 kJ) and nutrients with s.d.ds comparable to intra-individual variations in the general population. The differences in energy intake were randomly distributed over the range of intakes. CONCLUSIONS The present study demonstrates that standardized three day dietary records show a high degree of repeatability within a short period of time in a sample of European IDDM patients. The good repeatability strengthens the conclusions drawn from the nutritional data in the EURODIAB IDDM Complications Study.

Abstract
Human plasma phospholipid transfer protein (PLTP) circulates bound to high density lipoprotein (HDL) and mediates both net transfer and exchange of phospholipids between different lipoproteins. However, its overall function in lipoprotein metabolism is unknown. To assess the effects of increased plasma levels of PLTP, human PLTP transgenic mice were established using the human PLTP gene driven by its natural promoter. One line of PLTP transgenic mice with moderate expression of PLTP mRNA and protein was obtained. The order of human PLTP mRNA expression in tissues was: liver, kidney, brain, small intestine > lung > spleen > heart, adipose tissue. Western blotting using a human PLTP monoclonal antibody revealed authentic human PLTP (Mr 80 kD) in plasma. Plasma PLTP activity was increased by 29% in PLTP transgenic mice. However, plasma lipoprotein analysis, comparing PLTP transgenic mice to control littermates, revealed no significant changes in the plasma lipoprotein lipids or apolipoproteins. Since previous studies have shown that human cholesteryl ester transfer protein and lecithin:cholesterol acyltransferase only function optimally in human apoAI transgenic mice, the human PLTP transgenic mice were cross-bred with human apoAI transgenic mice. In the human apoAI transgenic background, PLTP expression resulted in increased PLTP activity (47%), HDL phospholipid (26%), cholesteryl ester (24%), free cholesterol (37%), and apoAI (22%). There was a major increase of apoAI in prebeta-HDL (56%) and a small increase in alpha-HDL (14%). The size distribution of HDL particles within alpha- and prebeta-migrating species was not changed. The results suggest that PLTP increases the influx of phospholipid and secondarily cholesterol into HDL, leading to an increase in potentially antiatherogenic prebeta-HDL particles.

Abstract
OBJECTIVE To help people who give health information to the public develop the skills they need to make sense of evidence about effectiveness. DESIGN Educational approach, preceded by careful planning with representatives of possible participants. SETTING AND STUDY OF PARTICIPANTS: Staff in consumer health information services and members of maternity self-help groups in the UK in summer 1995. INTERVENTIONS Pairs of half-day workshops introducing participants to randomised controlled trials and systematic reviews and to their critical appraisal. The workshops were run participatively and had at their centre a critical appraisal session in small groups. MAIN OUTCOME MEASURES Attendance at workshops, satisfaction and enjoyment of workshops; comments at a follow-on event. RESULTS Four pairs of workshops were held (three for consumer health information services, one for maternity self-help groups), 54 people attended a pair of workshops and a further 34 attended individual workshops. The workshops were enjoyed and found to be a good use of time. CONCLUSIONS It is feasible to introduce critical appraisal skills to people whose primary role is to give health information to the public. There is a need for comparative evaluation of different approaches.

Abstract
The EURODIAB IDDM Complications Study, a cross-sectional, clinic-based study, was designed to measure the prevalence of diabetic complications in stratified samples of European insulin-dependent diabetic (IDDM) patients. As diet may be related to diabetic complications, nutritional intake was analysed in the study population. The aims of this first nutritional paper are to describe the nutrient intake in 2868 IDDM patients from 30 centres in 16 countries throughout Europe, to investigate the degree of regional differences in nutrient intake and to compare current intakes with recommended levels. Nutritional intake from 1458 male and 1410 female IDDM patients was assessed by a validated 3-day record (two weekdays, Sunday) and centrally analysed. Mean energy intake for all patients was 2390 +/- 707 kcal/day. Mean protein intake was 1.5 +/- 0.5 g/kg body weight. Carbohydrate intake was 43% and fibre intake 18 g/day. Alcohol intake for the total cohort was 2% of energy. Total fat contributed 38% of energy, with 14% from saturated fat. The Italian centres reported lower total and saturated fat intakes compared with other centres. Recommendations from the Diabetes and Nutrition Study Group of the EASD for total fat, saturated fatty acids and carbohydrate were only achieved by 14%, 14% and 15% of patients, respectively. The data of the present study clearly indicate current problems in the nutritional intake of European IDDM patients. These findings contribute to the definition of future targets in the nutritional management of IDDM patients, to be achieved as part of the initiatives taken by the St. Vincent Declaration action programme.

STUDY OBJECTIVE To identify randomised controlled trials (RCTs) published in the Journal of Epidemiology and Community Health and to explore the contribution of these to the evaluation of public health issues. DESIGN Hand searching of the journal by both authors with independent assessment of topics of the reports and of their relevance to the Cochrane Collaboration. Agreement was assessed using kappa scores. SETTING All papers and letters published in the journal from the first issue to the end of 1994. SUBJECTS Reports that might be RCTs were collected and classified into seven categories: definitely/probably/possibly RCTs or quasi-RCTs; or none of these. MAIN RESULTS Eighty two definite RCTs were identified and a further 23 were probably/possibly RCTs or quasi-RCTs. Most reports dealt with health education, drug treatments, or "other" health service interventions. Both authors failed to identify a number of trials on hand searching. CONCLUSIONS The journal has published many trials of importance to the development of evidence-based public health policy. Hand searching may need to be done independently by more than one person.

Abstract
OBJECTIVES The introduction of an internal market in the British National Health Service (NHS) has highlighted the importance of developing appropriate, valid and timely measures of hospital activity, both for the purposes of specifying and monitoring contracts and for evaluating the success of the NHS reforms in general. This paper compares the validity of five case mix methods (Diagnosis Related Groups (DRGs); Healthcare Resource Groups (HRGs) versions 1 and 2; specialty classification; a simple age categorization) in predicting resource use. METHODS Two data sets were used to compare different case mix methods. A 3% random sample (n approximately equal to 300,000) of the 1992/3 Hospital Episodes Statistics was used to test their ability to predict variation in length of stay, and a second set of individually costed patient episodes from two hospitals (n approximately equal to 40,000) was used to test their ability to explain cost variation. Analysis of variance models were used to assess the fit of each of the case mix systems to test data and a simple significance test of differences in mean squared error between models was applied. RESULTS All case mix methods performed poorly on untrimmed data. When lengths of stay greater than 29 days were excluded, version 2 of HRGs explained 31% of total variance in length of stay and 25% of cost variation. DRGs explained less variance but performed better than HRGs version 1. For a typical hospital patient population consisting of a range of specialties, the difference in explanatory power between HRGs V2 and DRGs was statistically significant at the 5% level for sample sizes of approximately 2000 or greater. For individual specialties, the minimum sample size required for the difference between the groupers to be significant ranged from around 300 to over 2000. CONCLUSIONS The locally developed HRGs version 2 system appears to offer superior performance in terms of resource homogeneity to other currently available approaches. It is also more adaptable and cheaper than imported alternatives and has been formally endorsed by the UK medical Royal Colleges.
