Examining the frequency and nature of gambling marketing in televised broadcasts of professional sporting events in the United Kingdom.

OBJECTIVE: Gambling operators in the United Kingdom have introduced a voluntary ban on adverts broadcast during televised sport before 21:00 (the 'whistle-to-whistle' ban). To inform debates around the potential effectiveness of this ban, we examine the frequency and nature of gambling marketing in televised broadcasts across professional sporting events. STUDY DESIGN: Frequency analysis of verbal and visual gambling marketing references during television broadcasts of football (n = 5), tennis, Formula 1, boxing and rugby union (each n = 1) from 2018. METHODS: For each gambling reference, we coded: whether it appeared in-play or out-of-play; location (e.g. pitch-side advertising); format (e.g. branded merchandise); duration (s); number of identical references visible simultaneously; brand; and presence of age restriction or harm-reduction messages. RESULTS: Boxing contained the most gambling references, on average, per broadcast minute (4.70 references), followed by football (2.75), rugby union (0.55) and tennis (0.11). Formula 1 contained no gambling references. In boxing, references most frequently appeared within the area-of-play. For football and rugby union, references most frequently appeared around the pitch border or within the area-of-play (e.g. branded shirts). Only a small minority of references were for adverts during commercial breaks that would be subject to the whistle-to-whistle ban (e.g. 2% of references in football). Less than 1% of references in boxing and only 3% of references in football contained age restriction or harm-reduction messages. CONCLUSIONS: As gambling sponsorship extends much beyond adverts in commercial breaks, the 'whistle-to-whistle' ban will have limited effect on gambling exposure. Gambling sponsorship activities rarely contain harm-reduction messages.

Visibility of age restriction warnings, harm reduction messages and terms and conditions: a content analysis of paid-for gambling advertising in the United Kingdom.

OBJECTIVE: The inclusion and design of age restriction warnings, harm reduction messages and terms and conditions (T&Cs) in gambling advertising is self-regulated in the United Kingdom. Our study examines the visibility and nature of this information in a sample of paid-for gambling adverts. STUDY DESIGN: A content analysis of a stratified random sample of gambling adverts (n = 300) in the United Kingdom from eight paid-for advertising channels (March 2018). METHODS: For each advert, we assessed whether any age restriction warnings, harm reduction messages and T&Cs were present. If so, visibility was scored on a five-point scale ranging from very poor (≤10% of advert space) to very good (≥26% of advert), which had high inter-rater reliability. Descriptive information on position, design and tone of language was recorded. RESULTS: One in seven adverts (14%) did not feature an age restriction warning or harm reduction message. In adverts that did, 84% of age restriction warnings and 54% of harm reduction messages had very poor visibility. At least one in ten adverts did not contain T&Cs. In adverts that did, 73% had very poor visibility. For age restriction warnings, harm reduction messages and T&Cs, most appeared in small fonts and outside the main advert frame. Most harm reduction messages did not actually reference gambling-related harms. CONCLUSION: Age restriction warnings, harm reduction messages and T&Cs do not always appear in paid-for gambling advertising. When they do, visibility is often very poor and the messaging not clear. The findings do not support a self-regulatory approach to managing this information in gambling adverts.

Impact of a targeted direct marketing price promotion intervention (Buywell) on food-purchasing behaviour by low income consumers: a randomised controlled trial.

BACKGROUND: Price promotions are a promising intervention for encouraging healthier food purchasing. We aimed to assess the impact of a targeted direct marketing price promotion combined with healthy eating advice and recipe suggestions on the purchase of selected healthier foods by low income consumers. METHODS: We conducted a randomised controlled trial (n = 53 367) of a direct marketing price promotion (Buywell) combined with healthy eating advice and recipe suggestions for low income consumers identified as 'less healthy' shoppers. Impact was assessed using electronic point of sale data for UK low income shoppers before, during and after the promotion. RESULTS: The proportion of customers buying promoted products in the intervention month increased by between 1.4% and 2.8% for four of the five products. There was significantly higher uptake in the promotion month (P < 0.001) for the intervention group than would have been expected on the basis of average uptake in the other months. When product switching was examined for semi-skimmed/skimmed milk, a modest increase (1%) was found in the intervention month of customers switching from full-fat to low-fat milk. This represented 8% of customers who previously bought only full-fat milk. The effects were generally not sustained after the promotion period. CONCLUSIONS: Short-term direct marketing price promotions combined with healthy eating advice and recipe suggestions targeted at low income consumers are feasible and can have a modest impact on short-term food-purchasing behaviour, although further approaches are needed to help sustain these changes.

Young people's exposure to point-of-sale tobacco products and promotions.

OBJECTIVES: Point of sale (POS) displays are one of the most important forms of tobacco marketing still permitted in many countries. Reliable methods for measuring exposure to such displays are needed in order to assess their potential impact, particularly on smoking attitudes and uptake among young people. In this study we use a novel method for evaluating POS exposure based on young people's use of retail outlets and recall of tobacco displays and observational data on the characteristics of displays. STUDY DESIGN: Observational audit of retail outlets (n = 96) and school-based pupil survey (n = 1482) in four Scottish communities reflecting different levels of social deprivation and urbanisation, conducted in 2013 before legislation to remove POS displays was implemented in supermarkets. METHODS: Measures were taken of: visibility and placement of tobacco displays; internal and external advertising; display unit size, branding and design; visibility of pack warnings; proximity of tobacco products to products of potential interest to children and young people; pupils' self-reported frequency of visiting retail outlets; and pupils' recall of tobacco displays. Variation in POS exposure across social and demographic groups was assessed. RESULTS: Displays were highly visible within outlets and, in over half the stores, from the public footway outside. Tobacco products were displayed in close proximity to products of interest to children (e.g. confectionery, in 70% of stores). Eighty percent of pupils recalled seeing tobacco displays, with those from deprived areas more likely to recall displays in small shops. When confectioners, tobacconists and newsagents (CTNs) and grocery/convenience stores (two of the outlet types most often visited by young people) were examined separately, average tobacco display unit sizes were significantly larger in those outlets in more deprived areas. CONCLUSIONS: POS displays remain a key vector in most countries for advertising tobacco products, and it is important to develop robust measures of exposure. The data reported in this paper provide a baseline measure for evaluating the efficacy of legislation prohibiting such displays.

Mating system and early viability resistance to habitat fragmentation in a bird-pollinated eucalypt.

Habitat fragmentation has been shown to disrupt ecosystem processes such as plant-pollinator mutualisms. Consequently, mating patterns in remnant tree populations are expected to shift towards increased inbreeding and reduced pollen diversity, with fitness consequences for future generations. However, mating patterns and phenotypic assessments of open-pollinated progeny have rarely been combined in a single study. Here, we collected seeds from 37 Eucalyptus incrassata trees from contrasting stand densities following recent clearance in a single South Australian population (intact woodland=12.6 trees ha(-1); isolated pasture=1.7 trees ha(-1); population area=10 km(2)). 649 progeny from these trees were genotyped at eight microsatellite loci. We estimated genetic diversity, spatial genetic structure, indirect contemporary pollen flow and mating patterns for adults older than the clearance events and open-pollinated progeny sired post-clearance. A proxy of early stage progeny viability was assessed in a common garden experiment. Density had no impact on mating patterns, adult and progeny genetic diversity or progeny growth, but was associated with increased mean pollen dispersal. Weak spatial genetic structure among adults suggests high historical gene flow. We observed preliminary evidence for inbreeding depression related to stress caused by fungal infection, but which was not associated with density. Higher observed heterozygosities in adults compared with progeny may relate to weak selection on progeny and lifetime-accumulated mortality of inbred adults. E. incrassata appears to be resistant to the negative mating pattern and fitness changes expected within fragmented landscapes. This pattern is likely explained by strong outcrossing and regular long-distance pollen flow.

Strengthening clinical cancer research in the United Kingdom.

BACKGROUND: In 1999, 270,000 cases of cancer were registered in the United Kingdom, placing a large burden on the NHS. Cancer outcome data in 1999 suggested that UK survival rates were poorer than most other European countries. In the same year, a Department of Health review noted that clinical trials accrual was poor (<3.5% of incident cases) and hypothesised that increasing research activity might improve outcomes and reduce the variability of outcomes across England. Thus, the National Cancer Research Network (NCRN) was established to increase participation in cancer clinical research. METHODS: The NCRN was established in 2001 to provide a robust infrastructure for cancer clinical research and improvements in patient care. Remit of NCRN is to coordinate, support and deliver cancer clinical research through the provision of research support staff across England. The NCRN works closely with similar networks in Scotland, Wales and the Northern Ireland. A key aim of NCRN is to improve the speed of research and this was also assessed by comparing the speed of study delivery of a subset of cancer studies opening before and after NCRN was established. RESULTS: Patient recruitment increased through NCRN, with almost 32,000 (12% of annual incident cases) cancer patients being recruited each year. Study delivery has improved, with more studies meeting the recruitment target - 74% compared with 39% before NCRN was established. CONCLUSION: The coordinated approach to cancer clinical research has demonstrated increased accrual, wide participation and successful trial delivery, which should lead to improved outcomes and care.

Research-intensive cancer care in the NHS in the UK.

In the late 1990 s, in response to poor national cancer survival figures, government monies were invested to enhance recruitment to clinical cancer research. Commencing with England in 2001 and then rolling out across all four countries, a network of clinical cancer research infrastructure was created, the new staff being linked to existing clinical care structures including multi-disciplinary teams. In parallel, a UK-wide co-ordination of cancer research funders driven by the 'virtual' National Cancer Research Institute, combined to create a 'whole-system approach' linking research funders, researchers and NHS clinicians all working to the same ends. Over the next 10 years, recruitment to clinical trials and other well-designed studies, increased 4-fold, reaching 17% of the incident cancer population, the highest national rate world-wide. The additional resources led to more studies opened, and more patients recruited across the country, for all types of cancers and irrespective of additional clinical research staff in some hospitals. In 2006, a co-ordinated decision was made to increasingly focus on randomized trials, leading to increased recruitment, without any fall-off in accrual to non-randomized and observational studies. The National Cancer Research Network has supported large successful trials which are changing clinical practice in many cancers.

Extending the clinical research network approach to all of healthcare.

The development of Clinical Research Networks (CRN) has been central to the work conducted by Health Departments and research funders to promote and support clinical research within the NHS in the UK. In England, the National Institute for Health Research has supported the delivery of clinical research within the NHS primarily through CRN. CRN provide the essential infrastructure within the NHS for the set up and delivery of clinical research within a high-quality peer-reviewed portfolio of studies. The success of the National Cancer Research Network is summarized in Chapter 5. In this chapter progress in five other topics, and more recently in primary care and comprehensively across the NHS, is summarized. In each of the 'topic-specific' networks (Dementias and Neurodegenerative Diseases, Diabetes, Medicines for Children, Mental Health, Stroke) there has been a rapid and substantial increase in portfolios and in the recruitment of patients into studies in these portfolios. The processes and the key success factors are described. The CRN have worked to support research supported by pharmaceutical, biotechnology and medical device companies and there has been substantial progress in improving the speed, cost and delivery of these 'industry' studies. In particular, work to support the increased speed of set up and delivery of industry studies, and to embed this firmly in the NHS, was explored in the North West of England in an Exemplar Programme which showed substantial reductions in study set-up times and improved recruitment into studies and showed how healthcare (NHS) organizations can overcome delays in set up times when they actively manage the process. Seven out of 20 international studies reported that the first patient to be entered anywhere in the world was from the UK. In addition, the CRN have supported research management and governance, workforce development and clinical trials unit collaboration and coordination. International peer reviews of all of the CRN have been positive and resulted in the continuation of the system for a further 5 years in all cases.

Surgery for movement disorders.

Over past three decades, there has been a resurgence of interest in functional neurosurgery for movement disorders. Recently, thanks to the increased understanding of cellular pathophysiology and advances in technology and surgical techniques, deep brain stimulation (DBS) has essentially replaced ablative procedures for most of these conditions. Success of DBS treatment in the movement disorders depends on the recognized limitations in the medical treatment, our understanding of the anatomy and physiology of these disorders and, particularly, involvement of neurologists, neurosurgeons, clinical neurophysiologists and neuropsychiatrists in outcome studies of DBS surgery. Up to now, the exact mechanism of DBS is not fully understood. This review provides an overview of use of stereotactic neurosurgery, particularly DBS, for movement disorders, focusing mainly on the patient selection, target options, clinical outcome, adverse effects and possible mechanisms of DBS for advanced Parkinson's disease, dystonia, and essential tremor.

An international field study of the reliability and validity of a disease-specific questionnaire module (the QLQ-MY20) in assessing the quality of life of patients with multiple myeloma.

AIM: To test the reliability, validity and sensitivity of the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-MY24 questionnaire, designed to assess the quality of life of myeloma patients with the QLQ-C30. METHODS: The study was carried out through the EORTC Quality of Life Group using clinical trials in seven countries. All trials used the QLQ-C30 and QLQ-MY24 at baseline and a follow-up timepoint. RESULTS: Two hundred and forty patients participated. The questionnaires were acceptable to patients. The hypothesised scale structure (disease symptoms, side-effects, body image and future perspective) was confirmed by multi-trait scaling, internal consistency and correlation analysis. Most scales demonstrated sensitivity to change and discriminated between clinically different patients. The social support scale (4 items) was removed due to observed ceiling effects. CONCLUSION: The final questionnaire contains 20 items, QLQ-MY20, and is a reliable and valid instrument recommended for use with the QLQ-C30 in myeloma patients.

Does exposure to cigarette brands increase the likelihood of adolescent e-cigarette use? A cross-sectional study.

OBJECTIVE: To examine the relationship between tobacco cigarette brand recognition, and e-cigarette use in adolescents. DESIGN: Cross-sectional observational study. SETTING: High schools in Scotland. PARTICIPANTS: Questionnaires were administered to pupils in Secondary 2 (S2 mean age: 14.0 years) and Secondary 4 (S4 mean age: 15.9 years) across 4 communities in Scotland. An 86% response rate with a total sample of 1404 pupils was achieved. MAIN OUTCOME MEASURES: Self-reported previous use of e-cigarettes and self-reported intention to try e-cigarettes in the next 6 months. RESULTS: 75% (1029/1377) of respondents had heard of e-cigarettes (69.5% S2, 81.1% S4), and of these, 17.3% (10.6% S2, 24.3% S4 n=1020) had ever tried an e-cigarette. 6.8% (3.7% S2, 10.0% S4 n=1019) reported that they intended to try an e-cigarette in the next 6 months. Recognition of more cigarette brands was associated with greater probability of previous e-cigarette use (OR 1.20, 99% CI 1.05 to 1.38) as was having a best friend who smoked (OR 3.17, 99% CI 1.42 to 7.09). Intention to try e-cigarettes was related to higher cigarette brand recognition (OR 1.41, 99% CI 1.07 to 1.87), hanging around in the street or park more than once a week (OR 3.78, 99% CI 1.93 to 7.39) and living in areas of high tobacco retail density (OR 1.20, 99% CI 1.08 to 1.34). Never having smoked was a protective factor for both future intention to try, and past e-cigarette use (OR 0.07, 99% CI 0.02 to 0.25; and OR 0.10, 99% CI 0.07 to 0.16, respectively). CONCLUSIONS: Higher cigarette brand recognition was associated with increased probability of previous use and of intention to use e-cigarettes. The impact of tobacco control measures such as restricting point-of-sale displays on the uptake of e-cigarettes in young people should be evaluated.

Automated collection of quality-of-life data: a comparison of paper and computer touch-screen questionnaires.

PURPOSE: To evaluate alternative automated methods of collecting data on quality of life (QOL) in cancer patients. After initial evaluation of a range of technologies, we compared computer touch-screen questionnaires with paper questionnaires scanned by optical reading systems in terms of patients' acceptance, data quality, and reliability. PATIENTS AND METHODS: In a randomized cross-over trial, 149 cancer patients completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, version 2.0 (EORTC QLQ-C30), and the Hospital Anxiety and Depression Scale (HADS) on paper and on a touch screen. In a further test-retest study, 81 patients completed the electronic version of the questionnaires twice, with a time interval of 3 hours between questionnaires. RESULTS: Fifty-two percent of the patients preferred the touch screen to paper; 24% had no preference. The quality of the data collected with the touch-screen system was good, with no missed responses. At the group level, the differences between scores obtained with the two modes of administration of the instruments were small, suggesting equivalence for most of the QOL scales, with the possible exception of the emotional, fatigue, and nausea/vomiting scales and the appetite item, where patients tended to give more positive responses on the touch screen. At the individual patient level, the agreement was good, with a kappa coefficient from 0.57 to 0.77 and percent global agreement from 61% to 97%. The electronic questionnaire had good test-retest reliability, with correlation coefficients between the two administrations from 0.78 to 0.95, kappa coefficients of agreement from 0.55 to 0.90, and percent global agreement from 56% to 100%. CONCLUSION: Computer touch-screen QOL questionnaires were well accepted by cancer patients, with good data quality and reliability.

The hippocampus as a cognitive graph.

A theory of cognitive mapping is developed that depends only on accepted properties of hippocampal function, namely, long-term potentiation, the place cell phenomenon, and the associative or recurrent connections made among CA3 pyramidal cells. It is proposed that the distance between the firing fields of connected pairs of CA3 place cells is encoded as synaptic resistance (reciprocal synaptic strength). The encoding occurs because pairs of cells with coincident or overlapping fields will tend to fire together in time, thereby causing a decrease in synaptic resistance via long-term potentiation; in contrast, cells with widely separated fields will tend never to fire together, causing no change or perhaps (via long-term depression) an increase in synaptic resistance. A network whose connection pattern mimics that of CA3 and whose connection weights are proportional to synaptic resistance can be formally treated as a weighted, directed graph. In such a graph, a "node" is assigned to each CA3 cell and two nodes are connected by a "directed edge" if and only if the two corresponding cells are connected by a synapse. Weighted, directed graphs can be searched for an optimal path between any pair of nodes with standard algorithms. Here, we are interested in finding the path along which the sum of the synaptic resistances from one cell to another is minimal. Since each cell is a place cell, such a path also corresponds to a path in two-dimensional space. Our basic finding is that minimizing the sum of the synaptic resistances along a path in neural space yields the shortest (optimal) path in unobstructed two-dimensional space, so long as the connectivity of the network is great enough. In addition to being able to find geodesics in unobstructed space, the same network enables solutions to the "detour" and "shortcut" problems, in which it is necessary to find an optimal path around a newly introduced barrier and to take a shorter path through a hole opened up in a preexisting barrier, respectively. We argue that the ability to solve such problems qualifies the proposed hippocampal object as a cognitive map. Graph theory thus provides a sort of existence proof demonstrating that the hippocampus contains the necessary information to function as a map, in the sense postulated by others (O'Keefe, J., and L. Nadel. 1978. The Hippocampus as a Cognitive Map. Clarendon Press, Oxford, UK). It is also possible that the cognitive mapping functions of the hippocampus are carried out by parallel graph searching algorithms implemented as neural processes. This possibility has the great attraction that the hippocampus could then operate in much the same way to find paths in general problem space; it would only be necessary for pyramidal cells to exhibit a strong nonpositional firing correlate.

A randomised study of whole-breast vs tumour-bed irradiation after local excision and axillary dissection for early breast cancer.

AIMS: Whole-breast radiotherapy (WBRT) after conservative surgery for early breast cancer is a routine standard of care. Despite this, a number of uncertainties in management still exist. Over recent years, a number of new technologies have allowed the development of partial-breast irradiation, with the intention of improving the risk-benefit relationship of routine breast radiotherapy. We report the results of a trial comparing partial- with WBRT, with prolonged follow-up. MATERIALS AND METHODS: Between 1986 and 1990, 174 women were randomised to receive conventional whole-breast radiotherapy (WBRT) (40 Gy in 15 fractions), with a tumour-bed boost or partial-breast irradiation by a variety of techniques. Recruitment was problematic, and the trial closed prematurely well before meeting its recruitment target. RESULTS: A trend was observed towards higher local recurrence and a higher locoregional recurrence rate after irradiation of the tumour bed alone. Distant recurrence and survival were the same. CONCLUSIONS: Conclusions are limited in view of the failure to complete accrual of the target of 400 participants, and in the context of the techniques of partial-breast radiotherapy used during this study, which would not compare with those in current use. Tumour-bed irradiation alone cannot currently be recommended as routine treatment outside the context of clinical trial.

E-cigarette marketing in UK stores: an observational audit and retailers' views.

OBJECTIVES: To explore how e-cigarettes are being promoted at point of sale in the UK and how retailers perceive market trends. SETTING: Fixed retail outlets subject to a ban on the display of tobacco products. PARTICIPANTS: Observational audit of all stores selling tobacco products (n=96) in 4 Scottish communities, conducted over 2 waves 12 months apart (2013-2014), and qualitative interviews with small retailers (n=25) in 4 matched communities. PRIMARY AND SECONDARY OUTCOME MEASURES: The audit measured e-cigarette display characteristics, advertising materials and proximity to other products, and differences by area-level disadvantage. Interviews explored retailers' perceptions of e-cigarette market opportunities and risks, and customer responses. RESULTS: The number of e-cigarette point-of-sale display units and number of brands displayed increased between waves. E-cigarettes were displayed close to products of interest to children in 36% of stores. Stores in more affluent areas were less likely to have external e-cigarette advertising than those in deprived areas. Although e-cigarettes delivered high profit margins, retailers were confused by the diversity of brands and products, and uncertain of the sector's viability. Some customers were perceived to purchase e-cigarettes as cessation aids, and others, particularly low-income smokers, as a cheaper adjunct to conventional tobacco. CONCLUSIONS: E-cigarette point-of-sale displays and number of brands displayed increased over 12 months, a potential cause for concern given their lack of regulation. Further scrutiny is needed of the content and effects of such advertising, and the potentially normalising effects of placing e-cigarettes next to products of interest to children.

Assessing the relative costs of standard open surgery and laparoscopic surgery in colorectal cancer in a randomised controlled trial in the United Kingdom.

The role of laparoscopic surgery for the treatment of colorectal cancer is being explored in a multi-centre, randomised clinical trial in the UK, the MRC CLASICC Trial (Conventional versus Laparoscopic-assisted Surgery in Colorectal Cancer). An important end-point of the trial is the cost-effectiveness of laparoscopic surgery compared with that of conventional open surgery. The economic evaluation of this trial has been modelled on that in a similar trial being conducted in the USA in colon cancer. The aim of this paper is to discuss the rationale for modelling the UK trial on the US trial, and to describe the adaptations necessary for the UK trial. The parallel design of the economic evaluation in both trials will provide a unique opportunity to compare the cost implications of incorporating laparoscopic surgery in the UK and the USA, and to determine any cross-cultural differences. The UK trial will also provide information about the cost-effectiveness of laparoscopic surgery in rectal cancer.

Modified ice study: a phase II study of an intensive, modified ICE regimen (ifosfamide, carboplatin and etoposide) in patients with better prognosis, small cell lung cancer.

A total of 30 with good prognosis small cell lung cancer were treated with a modified 'ICE' (ifosfamide, carboplatin and etoposide) chemotherapy regimen in an attempt to achieve a high response rate with less toxicity than is seen with the full 'ICE' regimen. This was given every 4 weeks for a maximum of six cycles. In total 25 patients (83%, 95% CI (70-97%)) experienced a partial or complete response at some stage of their treatment. Of these patients, 12 (40%, 95% CI (22-58%)) showed a complete response. A total of 19 patients (63%) had to have their dose reduced and/or delayed at some point due to toxicity. Nadir blood counts showed that 19 patients (63%, 95% CI (46-81%)) had WHO grade 3 or 4 thrombocytopenia, and 24 (86%, 95% CI (73-99%)) had grade 3 or 4 neutropenia. A total of 17 patients (53%) completed six cycles of chemotherapy. In total 3 patients died during treatment all due to treatment-related complications. Median survival was 12.6 months (95% CI (11.6, 14.7 months)). Nausea, vomiting, dysphagia, activity, mood and overall condition, as recorded using daily diary cards, were worse at the beginning of each chemotherapy cycle. Both response rates and survival were clinically acceptable. However, neutropenia and thrombocytopenia, although reduced from rates reported with the full ICE regimen, were still high. A prospective randomised controlled trial is now needed to assess this regimen in more detail.

Improving uptake in non-attenders of breast screening: selective use of second appointment.

OBJECTIVE: To find the most cost and time effective way of increasing uptake by re-invitation of non-attenders after an initial invitation. SETTING: Women from the Warwickshire, Solihull, and Coventry breast screening programme who failed to attend their initial invitation. METHOD: Between October 1996 and February 1997, 2229 women who had failed to attend and had not declined their first invitation to screening were split into two groups according to their Sx number (a number allocated to all women when they are called for screening). Women with an odd number received a "open" invitation asking them to telephone the screening unit for another appointment and women with an even number were given a second "fixed" appointment time. The response of both groups of women was monitored. RESULTS: There was a significant difference (p < 0.001) in response to a second invitation between the open invitation and fixed appointment letter (12.3% v 22.8%). The greatest disparities were between those who had attended screening in both preceding rounds and those who had failed to attend either round. Socioeconomic status measured by Townsend scores did not seem to affect the response to second appointments. CONCLUSION: Second appointments are an important way of increasing screening uptake and thus reducing mortality, which should not be dismissed. The type of invitation is important, with fixed appointments being more effective, and the best predictor of attendance being attendance in the previous screening rounds. This information can be used to allocate resources efficiently to achieve an increased uptake. RECOMMENDATIONS: All women should receive a second invitation, ideally as a timed appointment. However, if this appointment strategy prevents an individual screening programme maintaining a three year cycle, we have identified a group of women for whom a simple reminder letter would maintain increased uptake while allowing savings in appointment scheduling.

"It's as if you're locked in": qualitative explanations for area effects on smoking in disadvantaged communities.

Evidence suggests that place of residence may be associated with smoking independently of individual poverty and socio-economic status. Qualitative research undertaken in disadvantaged communities in Glasgow explored possible pathways which might explain this 'area effect'. A poorly resourced and stressful environment, strong community norms, isolation from wider social norms, and limited opportunities for respite and recreation appear to combine not only to foster smoking but also to discourage or undermine cessation. Even the more positive aspects of life, such as support networks and identity, seem to encourage rather than challenge smoking. Policy and intervention responses need to tackle not only individual but also environmental disadvantage.

Synovial cysts in cats.

The clinical and radiographic appearance and histological findings in three cats with cystic extensions of the elbow joint capsule are described. The condition was only temporarily alleviated by surgical excision or drainage. In all cases the condition was associated with osteoarthritis.
