Abstract
Abstract
Aim
The accuracy and safety of symptom checkers in diagnosing and triaging patients is of concern; especially those with life-threatening conditions. The study's aims were to: 1. assess the accuracy of symptom checkers in diagnosing and triaging myocardial infarctions (MI) and, 2. determine whether differences in gender or presentation type exist.
Method
This prospective diagnostic accuracy study assessed 8 symptom checkers using 100 MI patients of various presentations: typical or atypical. The ability of a symptom checker in providing MI as the first diagnosis (D1) and the first 3 (D3) diagnoses were diagnostic accuracy measures. Triage advice was deemed correct if the symptom checker recommended seeking emergency treatment.
Results
Symptom checkers correctly diagnosed 48.0±31.4% of cases with MI first. D3 accuracy was 72.6±20.2%. Mean triage accuracy was 82.6±12.6%.
24.0±16.2% of atypical cases had a correct primary diagnosis. D3 accuracy for atypical MI was 43.8±20.6%, significantly lower than that of typical MI (p<0.01). Atypical case triage accuracy was 52.7±20.0%, significantly lower than typical cases (84.2±14.7%, p<0.01).
10.0% of the atypical female cases were diagnosed correctly with MI as the first diagnosis. Female atypical cases had significantly lower accuracy than typical female cases for all accuracy measures (p<0.01).
Conclusions
Symptom checkers generally provide low accuracy for diagnosing MI. Approximately 20% of cases were under-triaged. Results varied between symptom checkers: patients who presented with atypical symptoms tended to be under-diagnosed and under-triaged, especially those who were female. This demonstrated potential gender bias and therefore raises questions regarding symptom checker regulation and safety.

Abstract
Abstract
Introduction
Ascertain the prognostic role of in-vivo 4D-flow magnetic resonance imaging (MRI) and computational fluid dynamics (CFD) aortic haemodynamic parameters as predictors of adverse dissection-related events in type B aortic dissection (TBAD).
Methods
A systematic literature search was conducted according to the PRISMA guidelines using electronic databases searched from 1946 to 2021 for studies reporting on the relationship between aortic haemodynamics and aortic dissection-related events defined as aortic growth, aneurysm development, false lumen thrombosis, need for surgery and aortic rupture.
Results
Fourteen studies were included; eleven studies used CFD and three studies used 4D-flow MRI. Two studies found increased FL ejection fraction (EF) significantly associated with aortic growth rate, and another study found increased FL stroke volume significantly associated with increased aortic expansion rate. Result for time-averaged wall shear stress (TAWSS) and relative residence time (RRT) are contradictory; one study found TAWSS significantly associated with aortic wall deformation, but another study found no significant difference. Five studies suggested possible associations between slow flowing regions or increased RRT and FL thrombosis, with another study finding significant associations between FL thrombosis and adverse aortic outcomes. However, one study revealed opposite findings where decreased RRT significantly correlated with aneurysm formation.
Conclusion
In-vivo aortic haemodynamic measurements such as FL EF, FL stroke volume, TAWSS and RRT show possible associations with FL and aortic expansion, as well as FL thrombosis. Larger prospective studies are now needed to determine the prognostic utility of in vivo aortic haemodynamic metrics in predicting TBAD clinical outcomes to guide management.
Take-home message
Aortic haemodynamic parameters measured by 4D-flow magnetic resonance imaging and computational fluid dynamics show promising potential as predictors of adverse dissection-related events in type B aortic dissection.

Abstract
Objective To determine the frequency of germline and somatic pathogenic BRCA1 and BRCA2 variants in patients with high‐grade serous ovarian cancer tested by next‐generation sequencing (NGS), with the aim of defining the best strategy to be implemented in future routine testing. Design National retrospective audit. Setting The All Wales Medical Genomics Service (AWMGS). Population Patients with high‐grade serous ovarian/fallopian tube/peritoneal cancer referred by oncologists to the AWMGS between February 2015 and February 2021 for germline and/or tumour testing of the BRCA1 and BRCA2 genes by NGS. Methods Analysis of NGS data from germline and/or tumour testing. Main outcome measures Frequency of BRCA1 and BRCA2 pathogenic variants. Results The overall observed germline/somatic pathogenic variant detection rate was 11.6% in the 844 patients included in this study, with a 9.2% (73/791) germline pathogenic variant detection rate. Parallel tumour and germline testing was carried out for 169 patients and the overall pathogenic variant detection rate for this cohort was 14.8%, with 6.5% (11/169) shown to have a somatic pathogenic variant. Two BRCA1 dosage variants were found during germline screens, representing 2.0% (2/98) of patients with a pathogenic variant that would have been missed through tumour testing alone. Conclusions Parallel germline and tumour BRCA1 and BRCA2 testing maximises the detection of pathogenic variants in patients with high‐grade serous ovarian cancer. Tweetable abstract Parallel germline and tumour testing maximises BRCA pathogenic variant detection in ovarian cancer.

Abstract
Abstract
Aim
Prostate artery embolisation (PAE) is an approved treatment for men with lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH-LUTS). Evidence of efficacy for PAE in patients who are unable to void urine spontaneously is scant, however. Traditional treatments for BPH-LUTS have evidence in retention patients and this series aims to report outcomes for PAE in catheterised patients.
Method
The records of consecutive men with BPH-LUTS which required either an indwelling bladder catheter or clean intermittent self-catheterisation (CISC) who subsequently underwent PAE were retrospectively reviewed. Basic demographics were collected along with information on the prostate volume and PAE procedure specifics. The primary outcome was whether patients were catheter/CISC free at 3 months. Other outcomes include complications, use of medications and the need for other surgical treatments post-PAE.
Results
63 men underwent PAE for urinary retention and BPH-LUTS between 2013 and 2020. Of these, 7 underwent a unilateral embolisation for aberrant anatomy. The mean prostate volume was 128ml. 61% of men were free from a catheter/CISC post-treatment. 4 patients suffered post-PAE UTI, whilst 3 patients subsequently underwent Transurethral Resection of the Prostate following PAE for failure to become catheter free. 13 men were entirely free from BPH-LUTS medications.
Conclusions
PAE for catheterised men results in a similar catheter-free rate post procedure to several more invasive BPH treatments. It has a low side-effect profile and gives men with poor health an option to try to become catheter free. PAE should be discussed with men with catheters as a treatment option.

Dose-Volume Predictors for Patient-reported Late Diarrhoea, Faecal Incontinence and Urgency after Pelvic Radiotherapy. Clin Oncol (R Coll Radiol) 2021; 33:536-545. [PMID: 33875359 DOI: 10.1016/j.clon.2021.03.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 02/09/2021] [Accepted: 03/15/2021] [Indexed: 11/30/2022]
Abstract
AIMS Pelvic radiotherapy adds significantly to the curative treatment of many pelvic malignancies. However, this cure comes at a cost for many patients, where late bowel toxicities, such as faecal incontinence, urgency and diarrhoea, adversely affect quality of life. Despite the implementation of advanced radiotherapy techniques in many centres, there are deficiencies in our knowledge of how to make best use of these techniques to minimise these late toxicities, with dose-volume constraints specifically for late effects needing definition. The aims of this study were to establish dose-volume predictors for patient-reported late bowel toxicities and derive constraints for clinical use to reduce the risk of these toxicities. MATERIALS AND METHODS All radiotherapy patients treated in our institution between 2012 and 2014 for gynaecological and urological cancers (bladder, prostate where pelvic nodes are treated) were identified. Patients were sent patient-reported toxicity questionnaires at 12 and 24 months after treatment. Planning computed tomography scans were retrospectively contoured with different definitions of bowel as organs at risk (OARs). Dose-volume data for each OAR were collected and predictors of these toxicities found using multivariate analysis. For those dose-volume predictors found to be significant on multivariate analysis, statistically significant and clinically relevant dose-volume constraints were derived. Furthermore, data collected were used to validate constraints from published studies. RESULTS Faecal urgency, incontinence and diarrhoea rates were found in 52, 23.5 and 18.7% of the 203 patients included at 12 months following radiotherapy. Dose-volume parameters for sigmoid colon and large bowel were significant for these toxicities, and constraints for these OARs were derived, which are promising. A previously published constraint for bowel loops was validated with our data. CONCLUSIONS The sigmoid colon and large bowel are important OARs for the development of faecal urgency, incontinence and diarrhoea. Promising constraints for these OARs were derived, which require further validation before prospective clinical use.

Identifying Risk Factors for Anthracycline Chemotherapy-induced Phlebitis in Women with Breast Cancer: An Observational Study. Clin Oncol (R Coll Radiol) 2020; 33:230-240. [PMID: 33308947 DOI: 10.1016/j.clon.2020.11.025] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2020] [Revised: 10/25/2020] [Accepted: 11/25/2020] [Indexed: 11/15/2022]
Abstract
AIMS Anthracycline chemotherapy administered via a peripheral cannula results in severe anthracycline chemotherapy-induced phlebitis (ACIP) in about 20-30% of patients. Administering chemotherapy via a central venous catheter (CVC) prevents ACIP. However, CVCs are associated with an increased risk of thrombosis and sepsis. Our aim was to identify risk factors associated with severe ACIP and to provide evidence about the individual risk of developing symptoms. MATERIALS AND METHODS A prospective observational study of 263 women with breast cancer receiving peripheral administration of anthracycline chemotherapy at a UK cancer centre was conducted between May 2016 and January 2018. Data were collected at baseline and every 3 weeks following each chemotherapy treatment, using both healthcare professional- and participant-reported symptom assessments. RESULTS After three cycles of chemotherapy, 27% of participants experienced severe ACIP. Factors associated with symptom severity were identified as: arm used for chemotherapy administration, epirubicin dose, age, pre-existing hypertension, comorbidity, ethnic group and pain during chemotherapy administration. The sequence of arm used for chemotherapy administration was the single most significant factor (P < 0.001). When alternating arms were used no other risk factor was influential. Where alternating arms were not used, younger age and higher dose were associated with higher-grade symptoms, with age being more influential than dose. The cumulative effect of increasing symptom severity with repeated cycles was also identified (P < 0.001). CONCLUSION It is recommended that a CVC is not routinely required for women with breast cancer who have not undergone an axillary node clearance and receive chemotherapy in alternate arms. The need for a CVC for women who are planned to receive all anthracycline chemotherapy cycles in the same arm should be assessed in the light of peripheral venous access assessment and the key risk factors of age, dose and number of cycles.

Abstract
Abstract
Dr Liz Hanna chairs the Environmental Health Working Group of the WFPHA. For more than a decade she has researched climate change adaptation (CCA), focusing on exposure risks, physiological health impacts, health sector preparedness and policy responses to analyze current and future climate health threats. Working in Prof Tony McMichael's team at the Australian National University, she convened the National CCA Research Network, and served as President of the Climate and Health Alliance.
Human history is littered with examples of climatic interruptions to food and water supplies leading to disease and famine, conflict and migration. Dr Hanna sets the scene for this challenging workshop by outlining selected historical examples and describing the pathways of interconnectedness. Previously, climatic, health and social upheavals were geographically restricted. Yet the world now faces climatic change on a global scale never before it witnessed by humans. Liz outlines how this global disruption threatens our most important environmental determinants of health.
Evidence of global warming acceleration is presented and linked with disruptions to vital ecosystems and interruptions to food and water resources. Dr Hanna then leads participants on a journey to the future by applying IPCC projections to demonstrate the escalated potential for health harm from further intensified disturbances to the hydrological patterns, ocean warming, acidification and sea level rise, global heating and increased heat extremes as these impact water sources, crop yields, stock health and their survival, the marine food web and human acclimatisation limitations.
Throughout this presentation, Dr Hanna weaves the interconnectedness of healthy ecosystems and healthy people, and our global interconnectedness as we collectively share this beautiful but fragile planet.

Australia’s 2020 summer shows our changed climate future - a public health preparedness challenge. Eur J Public Health 2020.

Abstract
Abstract
Background
Humans have wandered this planet for hundreds of thousands of years, yet in the last 160 years we have dramatically disrupted planetary systems upon which we depend. Humanity has polluted the oceans, rivers, air and soils. Our persistent burning of fossil fuels to power opulent lifestyles is now perilously close to permanently disrupting global climatic systems.
Problem
It is clear. The problem is us. Australia's summer of horrors provides a terrifying glimpse into our collective future. This rich and exquisitely advantaged nation has voted for governments that have ignored fragile ecosystems, dismantled environmental protection laws, ignored climate science and expanded its fossil fuel exploration, extraction, consumption and exportation. It has systematically silenced science, ignored its duty of care to protect its present and future citizenry.
Evidence
The 2019-2020 summer brought unprecedented disasters to a country familiar with disasters. After the hottest and driest year on record came the world's largest bushfire, which started in winter, and burned uncontainable for 7 months across 5 states. Billions of animals perished, thousands of homes & businesses destroyed, 33 people burned alive. Continental-wide temperatures of 42oC. Smoke levels exceeded hazardous levels by a factor of 25, lingered 6weeks in the national capital, circumnavigated the southern hemisphere. 80% of Australians were affected by the fires in some way, and the nation fell into a deep grief.
The public health challenge
As the world faces new climate regimes, the associated health challenges are elevating to unheralded and unforeseen levels. Public health preparedness for past situations will inevitably fail. Events are no longer singular, short lived or readily managed. Today's events are multifaceted, expansive and protracted. Their sheer magnitude and scale prevent response activities, interrupt transport and supply chains and shut down power and communications.
Key messages
Unfettered human development has degraded planetary systems upon which humanity depends for survival and flourishing. Climate change is disrupting all our key environmental determinants of health. Environmental degradation and climate change now present a rapidly intensifying health emergency. Australia’s summer of disasters demonstrates we need an explosion of public health preparedness.

Overestimation of heat tolerance calls for health promotion to limit occupational heat risk. Eur J Public Health 2020.

Abstract
Abstract
Background
Global warming is accelerating. One degree C warming across Australia has generated a six-fold increase in heat extremes, as days above 35oC (and upwards of 45oC) are increasingly common. Many industries require staff to engage in outdoor work, often involving high levels of physical intensity. Compliance with occupational heat guidelines is reportedly low. Adoption of health protective strategies requires accurate risk perception. Australian heat exposed workers report discomfort when working in hot weather, yet little is known about their personal risk assessment.
Methods
Heat exposed outdoor workers across Australia (n = 112) completed pre-study surveys about their personal heat tolerance and completed daily heat diaries (n = 3421) to record their thermal comfort, heat symptoms and productivity, whilst on-site maximum temperatures and humidity were monitored.
Results
Daily maximum temperatures ranged from 18-43oC, and WBGT levels in parts of Australia exceed hazardous levels most days throughout summer. Significant overestimation of thermal tolerance was reported, as “feeling too hot to keep working” and emergence of symptoms occurred up to ten degrees lower than expected.
Conclusions
Heat exposed workers consistently over-estimate their thermotolerance and capacity to perform physically intensive work. Increasing frequency and intensity of heat waves escalates future risks of health harm and deaths among heat exposed workers. Health protection necessitates active health education/ health promotion campaigns to better align perceived and actual health risks. Main messages: Global warming presents intensifying health and productivity threats. Widespread lack of recognition of personal health threats suggests a critical need for heath education/promotion to increase heat guideline compliance
Key messages
Increasing frequency and intensity of heat waves from climate change escalates future risks of health harm and deaths among heat exposed workers who over-estimate their thermotolerance. Widespread lack of recognition of personal heat exposure threats suggests a critical need for health education/promotion to increase heat guidelines compliance.

The Three-item ALERT-B Questionnaire Provides a Validated Screening Tool to Detect Chronic Gastrointestinal Symptoms after Pelvic Radiotherapy in Cancer Survivors. Clin Oncol (R Coll Radiol) 2016; 28:e139-e147.

Abstract
AIMS Although pelvic radiotherapy is an effective treatment for various malignancies, around half of patients develop significant gastrointestinal problems. These symptoms often remain undetected, despite the existence of effective treatments. This study developed and refined a simple screening tool to detect common gastrointestinal symptoms in outpatient clinics. These symptoms have a significant effect on quality of life. This tool will increase detection rates and so enable access to specialist gastroenterologists, which will in turn lead to improved symptom control and quality of life after treatment. MATERIALS AND METHODS A literature review and expert consensus meeting identified four items for the ALERT-B (Assessment of Late Effects of RadioTherapy - Bowel) screening tool. ALERT-B was face tested for its usability and acceptability using cognitive interviews with 12 patients experiencing late gastrointestinal symptoms after pelvic radiotherapy. Thematic analysis and probe category were used to analyse interview transcripts. Interview data were presented to a group of experts to agree on the final content and format of the tool. ALERT-B was assessed for reliability and tested for validity against the Gastrointestinal Symptom Rating Scale in a clinical study (EAGLE). RESULTS Overall, the tool was found to be acceptable in terms of wording, response format and completion time. Participant-reported experiences, including lifestyle modifications and the psychological effect of the symptoms, led to further modifications of the tool. The refined tool includes three questions covering rectal bleeding, incontinence, nocturnal bowel movements and impact on quality of life, including mood, relationships and socialising. ALERT-B was successfully validated against the Gastrointestinal Symptom Rating Scale in the EAGLE study with the tool shown broadly to be internally consistent (Cronbach's α = 0.61 and all item-subscale correlation [Spearman] coefficients are > 0.6). CONCLUSION The ALERT-B screening tool can be used in clinical practice to improve post-treatment supportive care by triggering the clinical assessment of patients suitable for referral to a gastroenterologist.

Abstract
Ovarian cancer accounts for >140 000 deaths globally each year. Typically, disease is asymptomatic until an advanced, incurable stage. Although response to cytotoxic chemotherapy is frequently observed, resistance to conventional platinum-based therapies develop rapidly. Improved treatments are therefore urgently required. Virotherapy offers great potential for ovarian cancer, where the application of local, intraperitoneal delivery circumvents some of the limitations of intravenous strategies. To develop effective, adenovirus (Ad)-based platforms for ovarian cancer, we profiled the fluid and cellular components of patient ascites for factors known to influence adenoviral transduction. Levels of factor X (FX) and neutralizing antibodies (nAbs) in ascitic fluid were quantified and tumor cells were assessed for the expression of coxsackie virus and adenovirus receptor (CAR) and CD46. We show that clinical ascites contains significant levels of FX but consistently high CD46 expression. We therefore evaluated in vitro the relative transduction of epithelial ovarian cancers (EOCs) by Ad5 (via CAR) and Ad5 pseudotyped with the fiber of Ad35 (Ad5T*F35++) via CD46. Ad5T*F35++ achieved significantly increased transduction in comparison to Ad5 (P<0.001), independent of FX and nAb levels. We therefore propose selective transduction of CD46 over-expressing EOCs using re-targeted, Ad35-pseudotyped Ad vectors may represent a promising virotherapy for ovarian cancer.

Abstract
BACKGROUND Demand for healthcare services threatens to overwhelm the Australian healthcare system. Public hospitals have the largest component of expenditure growth and as such represent the largest opportunity for efficiency gains. Utilisation of inpatient hospital beds and in particular those on general medical units has not been studied in Australia. AIM To undertake a retrospective patient medical record review of 200 sequential admissions to the medical wards in two regional Tasmanian hospitals to determine the incidence of non-acute medical patient admission to the medical unit, and the subsequent days in hospital that were not required for medical reasons. The cost of these days was estimated. RESULTS Sixteen patient admissions (8%) could not be justified on medical grounds. Forty-eight (24%) patient admissions had at least one day hospital day that could not be justified on medical grounds. Of the 1438 total bed days, 475 (33%) were for non-medical reasons. The estimated cost of those non-medical bed days for this cohort was $764 800. CONCLUSIONS The incidence of non-acute medical admissions and non-acute medical bed days to the medical unit and associated cost was significant. Further research is needed to design alternative care provision for such patients particularly in regional Australia. The potential savings to the Australian healthcare system could be significant.

Training in clinical oncology: results of the Royal College of Radiologists' survey of new consultants. Clin Oncol (R Coll Radiol) 2012; 24:e143-8. [PMID: 22981545 DOI: 10.1016/j.clon.2012.08.005] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2012] [Revised: 07/23/2012] [Accepted: 08/02/2012] [Indexed: 11/29/2022]
Abstract
AIMS To seek the views of consultants appointed less than 2 years ago on the appropriateness of their training in fitting them to carry out their present posts, the FRCR examination, experience of research and the prevalence and value of out of programme experience and acting up as a consultant. MATERIALS AND METHODS All the consultants identified from the Royal College of Radiologists' database as having been appointed to a consultant post in the last 2 years were emailed inviting them to take part in a web-based survey. RESULTS The response rate was 60% (32 of 53 consultants). Ninety-four per cent agreed or strongly agreed that training had equipped them for clinical work as a consultant, but only 44% agreed or strongly agreed that training had equipped them to fulfil the management roles. Free text answers stressed the importance of management skills, getting involved with trial set-up and producing publications early in their career. Ninety-four per cent agreed or strongly agreed that they had adequate opportunity to develop skills in systemic therapy and radiotherapy planning, but only 56% thought this was the case for intensity-modulated radiotherapy and image-guided radiotherapy. Although 87% agreed or strongly agreed they had sufficient opportunity to develop teaching skills, this was only the case in 62% with regard to research skills. They published a median number of three papers in peer-reviewed journals. Twenty-five per cent of respondents studied for research degrees; 69% of consultants had undertaken out of programme experience and 50% had acted up as a consultant and these were generally found to be valuable experiences. There was strong support for the FRCR examination. CONCLUSIONS Consultants appointed in the last 2 years are generally satisfied with their training. Training in intensity-modulated radiotherapy and image-guided radiotherapy should be improved and the advanced specialist training requires reviewing to better fit consultants for subspecialisation, management and research.

Abstract
This study sought to investigate the impact of parity on the outcome of external cephalic version (ECV) over a 3-year period. In the study, 163 women with singleton uncomplicated breech pregnancy at term were offered ECV and 103 (63%) underwent the procedure. In 42 women, ECV was successful and 74% had a vaginal vertex delivery; whereas 61 women had a failed ECV and none had a vaginal vertex delivery. The probability of vaginal vertex delivery after ECV increased five-fold in nulliparous women (OR 5.2, 95% CI 1 - 42.8) and four-fold (OR 3.8, 95% CI 1.3 - 11.5) in multiparous women. After successful ECV, 50% of nulliparous women and 88.5% of multiparous women had a vaginal vertex delivery (p = 0.006). Neonatal outcome was favourable in all patients. We conclude that parity has little impact on efficacy of ECV, but significantly influences the overall chance of vaginal vertex delivery in women with an uncomplicated breech presentation at term.

Abstract
604 Background: There is wide variation in the use of breast MRI to screen the contralateral breast in patients recently diagnosed with unilateral breast cancer. Some centers routinely scan all patients with a recent diagnosis of breast cancer while others restrict breast MRI to patients with dense breast tissue, patients who are pre-menopausal, or patients with infiltrating lobular carcinoma. This international study evaluated performance measures of MRI by mammographic density, menopausal status and type of index cancer. Methods: 969 women from 21 sites with a recent diagnosis of unilateral breast cancer and a negative mammogram and CBE of the contralateral breast underwent breast MRI. Presence of breast cancer in the contralateral breast was determined by cancer positive breast biopsy within 12 months after study entry. Performance measures of breast MRI (cancer yield, sensitivity, specificity, negative predictive value, positive predictive value, biopsy rate) were compared between participant subsets defined by mammographic density (fatty vs dense), menopausal status (pre/peri menopausal vs post menopausal) and type of index cancer (invasive vs in situ and lobular vs non-lobular). Results: Performance measures of breast MRI were not influenced by breast density or index cancer histology. Cancer yield of MRI in dense breast women was 3% in both fatty and dense breasted women. Although cancer yield and sensitivity of MRI did not vary based on menopausal status, specificity was significantly higher among post-menopausal women in comparison to pre- or peri-menopausal women (p-value=0.002) as was positive biopsy rate (p-value 0.009). Conclusions: Performance of MRI in screening the contralateral breast in the newly diagnosed breast cancer patient is not influenced by breast density or index cancer histology. Specificity and positive biopsy rate are higher in post-menopausal women, which may be related to hormonal influences on breast tissue enhancement. [Table: see text]

Abstract
9101 Background: Radiofrequency Ablation (RFA) can destroy tissue in a defined area. Single institutions have reported that RFA can reduce pain from bone metastases. To confirm this, the American College of Radiology Imaging Network (ACRIN) completed a multicenter study of RFA for bone metastases. Methods: Eligible patients had bone pain in one dominant site: tumor size < 8 cm, and location > 1 cm from the spinal cord or cauda equina. RFA was performed under CT guidance. The Memorial Pain Assessment Card was used prior to RFA and repeated daily for two weeks, and at 1 and 3 months after RFA. AEs were recorded in addition to four different pain assessment measures: pain relief, patient mood, pain intensity, and pain severity. Results: Fifty-six patients had RFA at 9 centers. Metastatic sites were pelvis (24), chest wall (19), thoracolumbar spine (8), and extremities (5). Six out of 56 patients experienced at least one adverse event of grade 3 or higher, yielding an AE rate of 10.7% (95%CI is 2.6% to18.8%). AEs attributed directly to RFA were nerve injury in 2 patients. Of the 56 participants, 43 completed the 1 month follow-up and 33 completed the 3 month follow-up. At the time of this analysis, assuming that missing data were missing at random and after adjusting for all covariates, RFA showed significant effect in reducing pain at 1 and 3 month follow-up for all 4 pain assessment measures. The average increase in pain relief from pre-RFA to 1 month follow-up is 26.4 (P<0.0001) and the increase from pre-RFA to 3 month follow-up is 17.2 (P=0.003). The average increase in mood from pre-RFA to 1 month follow-up is 21.5 (P<0.0001) and the increase from pre-RFA to 3 month follow-up is 16.3 (P=0.001). The average decrease in pain intensity from pre-RFA to 1 month follow-up is 25.9 (P<0.0001) and the decrease from pre-RFA to 3 month follow-up is 13.0 (P=0.02). The odds of being in lower pain severity at 1 month follow-up is 12.6 (P<.0001) times higher than that at pre-RFA, and the odds at 3 month follow-up is 7.1 (P<0.0001) times higher than that at pre- RFA. Conclusions: This cooperative group trial confirms that RFA can safely palliate pain due to bone metastases. ACRIN receives funding from the National Cancer Institute through the grants U01 CA079778 and U01 CA080098. No significant financial relationships to disclose.

Abstract
BACKGROUND There is consensus in the literature that the end of life care for patients with chronic illness is suboptimal, but research on the specific needs of this population is limited. AIM This study aimed to use a mixed methodology and case study approach to explore the palliative care needs of patients with a non-cancer diagnosis from the perspectives of the patient, their significant other and the clinical team responsible for their care. Patients (n = 18) had a diagnosis of either end-stage heart failure, renal failure or respiratory disease. METHODS The Short Form 36 and Hospital and Anxiety and Depression Questionnaire were completed by all patients. Unstructured interviews were (n = 35) were conducted separately with each patient and then their significant other. These were followed by a focus group discussion (n = 18) with the multiprofessional clinical team. Quantitative data were analysed using simple descriptive statistics and simple descriptive statistics. All qualitative data were taped, transcribed and analysed using Colaizzi's approach to qualitative analysis. FINDINGS Deteriorating health status was the central theme derived from this analysis. It led to decreased independence, social isolation and family burden. These problems were mitigated by the limited resources at the individual's disposal and the availability of support from hospital and community services. Generally resources and support were perceived as lacking. All participants in this study expressed concerns regarding the patients' future and some patients described feelings of depression or acceptance of the inevitability of imminent death. CONCLUSION Patients dying from chronic illness in this study had many concerns and unmet clinical needs. Care teams were frustrated by the lack of resources available to them and admitted they were ill-equipped to provide for the individual's holistic needs. Some clinicians described difficulty in talking openly with the patient and family regarding the palliative nature of their treatment. An earlier and more effective implementation of the palliative care approach is necessary if the needs of patients in the final stages of chronic illness are to be adequately addressed.

Abstract
AIMS To explore Pakistani and Indian patients' experiences of, and views about, diabetes services in order to inform the development of culturally sensitive services. DESIGN Qualitative, interview study involving 23 Pakistani and nine Indian patients with Type 2 diabetes recruited from general practices and the local community in Edinburgh, Scotland. Data collection and analysis occurred concurrently and recruitment continued until no new themes emerged from the interviews. RESULTS Respondents expressed gratitude for the availability of free diabetes services in Britain, as they were used to having to pay to access health care on the Indian subcontinent. Most looked to services for the prompt detection and treatment of complications, rather than the provision of advice about managing their condition. As respondents attached importance to receiving physical examinations, they could be disappointed when these were not offered by health-care professionals. They disliked relying on interpreters and identified a need for bilingual professionals with whom they could discuss their diabetes care directly. CONCLUSIONS Gratitude for free services in Britain may instil a sense of indebtedness which makes it difficult for Pakistanis and Indians to be critical of their diabetes care. Health-care professionals may need to describe their roles carefully, and explain how different diabetes services fit together, to avoid Pakistani and Indian patients perceiving treatment as unsatisfactory. Whilst linkworker schemes may meet patients' need to receive culturally sensitive information in their first language, work is needed to assess their effectiveness and sustainability.

Abstract
AIMS In small cell lung cancer (SCLC), consolidation thoracic irradiation (CTI) increases 3-year absolute survival by 5.4% in patients with limited disease and a complete response to chemotherapy. Early concurrent thoracic radiotherapy has been shown to improve local control and prolong survival compared with CTI in some trials. The standard management of patients with SCLC in southeast Wales is CTI in individuals with limited disease and a complete response to chemotherapy. A review of patients with SCLC was carried out to establish whether survival locally is comparable with that reported in published studies, and if patients given CTI have survival comparable with that reported in studies where early concurrent thoracic radiotherapy was used. MATERIALS AND METHODS Between January 2000 and December 2002, 303 patients were registered with SCLC in southeast Wales. One hundred and fifteen (47%) patients had limited disease and 60/115 (52%) received CTI. RESULTS Patients with limited disease receiving CTI had a median survival of 17.7 months (95% confidence interval: 15-27.9 months). The 2- and 5-year survivals were 38 and 13%, respectively. CONCLUSIONS These results compare favourably with previously published studies on SCLC. There are no plans to change our current treatment policy for SCLC in southeast Wales.

Abstract
Type 2 diabetes is at least 4 times more common among British South Asians than in the general population. South Asians also have a higher risk of diabetic complications, a situation which has been linked to low levels of physical activity observed amongst this group. Little is known about the factors and considerations which prohibit and/or facilitate physical activity amongst South Asians. This qualitative study explored Pakistani (n = 23) and Indian (n = 9) patients' perceptions and experiences of undertaking physical activity as part of their diabetes care. Although respondents reported an awareness of the need to undertake physical activity, few had put this lifestyle advice into practice. For many, practical considerations, such as lack of time, were interwoven with cultural norms and social expectations. Whilst respondents reported health problems which could make physical activity difficult, these were reinforced by their perceptions and understandings of their diabetes, and its impact upon their future health. Education may play a role in physical activity promotion; however, health promoters may need to work with, rather than against, cultural norms and individual perceptions. We recommend a realistic and culturally sensitive approach, which identifies and capitalizes on the kinds of activities patients already do in their everyday lives.
