Abstract
BACKGROUND Half of mental health problems are established by the age of 14 years and 75% by 24 years. Early intervention and prevention of mental ill health are therefore vitally important. However, increased demand over recent years has meant that access to child mental health services is often restricted to those in severest need. Watch Me Play! (WMP) is an early intervention designed to support caregiver attunement and attention to the child to promote social-emotional well-being and thereby mental health resilience. Originally developed in the context of a local authority mental health service for children in care, it is now also delivered online as a low intensity, scalable, preventative intervention. Although WMP shows promise and is already used in some services, we do not yet know whether it is effective. METHODS A non-randomised single group feasibility study with embedded process evaluation. We propose to recruit up to 40 parents/carers of children aged 0-8 years who have been referred to early years and children's services in the UK. WMP involves a parent watching the child play and talking to their child about their play (or for babies, observing and following signals) for up to 20 min per session. Some sessions are facilitated by a trained practitioner who provides prompts where necessary, gives feedback, and discusses the child's play with the caregiver. Services will offer five facilitated sessions, and parents will be asked to do at least 10 additional sessions on their own with their child in a 5-week period. Feasibility outcomes examined are as follows: (i) recruitment, (ii) retention, (iii) adherence, (iv) fidelity of delivery, (v) barriers and facilitators of participation, (vi) intervention acceptability, (vii) description of usual care, and (viii) data collection procedures. Intervention mechanisms will be examined through qualitative interview data. Economic evaluation will be conducted estimating cost of the intervention and cost of service use for child and parents/carers quality-adjusted life years. DISCUSSION This study will address feasibility questions associated with progression to a future randomised trial of WMP. TRIAL REGISTRATION ISRCTN13644899 . Registered on 14th April 2023.

Abstract
INTRODUCTION Medical patients, admitted acutely to hospital, are at risk of venous thromboembolism (VTE). Clinical guidelines advise thromboprophylaxis prophylaxis for those at high risk of VTE. VTE is a common sequela of cancer, but guidelines take little consideration of cancer as an independent risk factor and their utility in palliative care patients is unclear. The hospice inpatient deep vein thrombosis (DVT) detection study (HIDDen) reported a 28% prevalence of asymptomatic iliofemoral DVT in hospice patients of poor performance status (PS) and prognosis, calling into question the utility of thromboprophylaxis in the palliative care setting. However, the majority of cancer inpatients receiving palliative care are admitted to hospital through the acute medical setting, yet their risk factors for VTE may differ from those admitted to hospices. OBJECTIVE To better understand the prevalence and behaviours of VTE in patients with cancer receiving palliative care who are admitted as an acute medical emergency. DESIGN Multicentre, observational cohort study. SETTING Secondary care acute hospitals in South Wales, UK. PATIENTS We plan to recruit 232 patients≥18 years old with a diagnosis of incurable cancer, and/or receiving palliative or best supportive care who are admitted acutely to hospital. Patients will be followed up for a maximum of 6 months following registration. PRIMARY OUTCOME Presence of lower extremity DVT. SECONDARY OUTCOMES Symptom burden attributed to DVT or pulmonary embolism, patient PS, patient demographics and development of new VTE within 90 days of registration. ANALYSIS The study statistical analysis plan will document analysis, methodology and procedures. ETHICS AND DISSEMINATION Ethical approval was obtained from the Wales Research Ethics Committee, reference 22/WA/0037 (IRAS 306352)-the main trial results will be analysed as soon as practically possible and the publication shared with investigators and on sponsor website; applications to access trial data will be subject to sponsor review process.

Abstract
Background Impaired double strand DNA repair by homologous repair deficiency (HRD) leads to sensitivity to poly ADP ribose polymerase (PARP) inhibition. Poly-ADP ribose polymerase (PARP) inhibitors target HRD to induce synthetic lethality and are used routinely in the treatment of BRCA1 mutated ovarian cancer in the platinum-sensitive maintenance setting. A subset of non-small cell lung cancers (NSCLCs) harbour impaired DNA double strand break repair. We therefore hypothesised that patients with metastatic non-small cell lung cancer exhibiting partial responses to platinum doublet-based chemotherapy, might enrich for impaired HRD, rendering these tumours more sensitive to inhibition of PARP inhibition by olaparib. Methods The Olaparib Maintenance versus Placebo Monotherapy in Patients with Advanced Non-Small Cell Lung Cancer trial (PIN) was a multicentre double-blind placebo controlled randomised phase II screening trial. This study was conducted at 23 investigative hospital sites in the UK. Patients had advanced (stage IIIB/IV) squamous (Sq) or non-squamous (NSq) NSCLC, and had to be chemo-naive, European Cooperative Oncology Group (ECOG) performance status 0-1. Prior immunotherapy with a PD1 or PDL1 inhibitor was allowed. Patients could be registered for PIN prior to (stage 1), or after (stage 2) initiation of induction chemotherapy. If any tumour shrinkage was observed (any shrinkage of RECIST target lesions), following a minimum of 3 cycles of platinum doublet chemotherapy, patients were randomised 1:1 using a centralised online system, to either olaparib (300 mg twice daily by mouth in 21-day cycles) or placebo, which was continued until disease progression, or unacceptable toxicity. Intention to treat (ITT) analyses of the primary endpoint included all randomised participants. Per protocol (PP) safety analysis included all participants who received at least one dose of study drug. Primary endpoint was progression-free survival (PFS), with a one-sided p-value of 0.2 to demonstrate statistical significance. Hazard ratios (HR) for PFS were both unadjusted and adjusted for the randomisation balancing factors (smoking status and histology). The trial was registered with ClinicalTrials.gov (NCT01788332) and EudraCT (2012-003383-51). Findings A total of 940 patients were assessed for stage 1 eligibility of whom 263 were registered between Feb 24, 2014 and Nov 7, 2017. 194 patients were excluded prior to stage 2 (no tumour shrinkage or unevaluable) and 70 were randomised; 32 (46%) to Olaparib and 38 (54%) to placebo. 4% (3/70) of patients randomised had a CR and 96% (67/70) had a PR (or other evidence of tumour response/mixed stable) during induction therapy. A total of 36 patients were registered in stage 2 only, i.e., post induction therapy. Intention to treat (ITT) unadjusted analysis showed a PFS hazard ratio (HR) of 0.83 (one-sided 80% CI upper limit 1.03, one-sided unadjusted log rank test p-value=0.23). ITT Cox-adjusted model showed a HR 0.73 (one-sided 80% CI upper limit 0.91, one sided p-value 0.11). Adverse events were reported in 31/32 subjects (97%) in the olaparib arm and 38/38 (100%) in the placebo group. The most commonly reported adverse events in the olaparib group were fatigue (20/31; 65%), nausea (17/31; 55%), anaemia (15/31; 48%) and dyspnea (13/31; 42%). In the placebo group the most common adverse events were fatigue (25/38; 66%), coughing (22/38; 58%), dyspnea (15/38; 39%) and nausea (11/38; 29%). There were no treatment-related deaths. Interpretation PFS was longer in the olaparib arm, but this did not reach statistical significance. When the PFS HR was adjusted for smoking status and histology, a significant difference at the one-sided 0.2 level was observed, suggesting that tumour control may be achieved for chemosensitive NSCLC treated with PARP monotherapy. We speculate that this signal may be driven by a molecular subgroup harbouring HRD.

Abstract
BACKGROUND Capivasertib, an AKT inhibitor, added to fulvestrant, was previously reported to improve progression-free survival in women with aromatase inhibitor-resistant oestrogen receptor (ER)-positive, HER2-negative advanced breast cancer. The benefit appeared to be independent of the phosphoinositide 3-kinase (PI3K)/AKT/phosphatase and tensin homologue (PTEN) pathway alteration status of tumours, as ascertained using assays available at the time. Here, we report updated progression-free survival and overall survival results, and a prespecified examination of the effect of PI3K/AKT/PTEN pathway alterations identified by an expanded genetic testing panel on treatment outcomes. METHODS This randomised, multicentre, double-blind, placebo-controlled, phase 2 trial recruited postmenopausal adult women aged at least 18 years with ER-positive, HER2-negative, metastatic or locally advanced inoperable breast cancer and an Eastern Cooperative Oncology Group performance status of 0-2, who had relapsed or progressed on an aromatase inhibitor, from across 19 hospitals in the UK. Participants were randomly assigned (1:1) to receive intramuscular fulvestrant 500 mg (day 1) every 28 days (plus a 500 mg loading dose on day 15 of cycle 1) with either capivasertib 400 mg or matching placebo, orally twice daily on an intermittent weekly schedule of 4 days on and 3 days off, starting on cycle 1 day 15. Treatment continued until disease progression, unacceptable toxicity, loss to follow-up, or withdrawal of consent. Treatment was allocated by an interactive web-response system using a minimisation method (with a 20% random element) and the following minimisation factors: measurable or non-measurable disease, primary or secondary aromatase inhibitor resistance, PIK3CA status, and PTEN status. The primary endpoint was progression-free survival in the intention-to-treat population. Secondary endpoints shown in this Article were overall survival and safety in the intention-to-treat population, and the effect of tumour PI3K/AKT/PTEN pathway status identified by an expanded testing panel that included next-generation sequencing assays. Recruitment is complete. The trial is registered with ClinicalTrials.gov, number NCT01992952. FINDINGS Between March 16, 2015, and March 6, 2018, 183 participants were screened for eligibility and 140 (77%) were randomly assigned to receive fulvestrant plus capivasertib (n=69) or fulvestrant plus placebo (n=71). Median follow-up at the data cut-off of Nov 25, 2021, was 58·5 months (IQR 45·9-64·1) for participants treated with fulvestrant plus capivasertib and 62·3 months (IQR 62·1-70·3) for fulvestrant plus placebo. Updated median progression-free survival was 10·3 months (95% CI 5·0-13·4) in the group receiving fulvestrant plus capivasertib compared with 4·8 months (3·1-7·9) for fulvestrant plus placebo (adjusted hazard ratio [HR] 0·56 [95% CI 0·38-0·81]; two-sided p=0·0023). Median overall survival in the capivasertib versus placebo groups was 29·3 months (95% CI 23·7-39·0) versus 23·4 months (18·7-32·7; adjusted HR 0·66 [95% CI 0·45-0·97]; two-sided p=0·035). The expanded biomarker panel identified an expanded pathway-altered subgroup that contained 76 participants (54% of the intention-to-treat population). Median progression-free survival in the expanded pathway-altered subgroup for participants receiving capivasertib (n=39) was 12·8 months (95% CI 6·6-18·8) compared with 4·6 months (2·8-7·9) in the placebo group (n=37; adjusted HR 0·44 [95% CI 0·26-0·72]; two-sided p=0·0014). Median overall survival for the expanded pathway-altered subgroup receiving capivasertib was 38·9 months (95% CI 23·3-50·7) compared with 20·0 months (14·8-31·4) for those receiving placebo (adjusted HR 0·46 [95% CI 0·27-0·79]; two-sided p=0·0047). By contrast, there were no statistically significant differences in progression-free or overall survival in the expanded pathway non-altered subgroup treated with capivasertib (n=30) versus placebo (n=34). One additional serious adverse event (pneumonia) in the capivasertib group had occurred subsequent to the primary analysis. One death, due to atypical pulmonary infection, was assessed as possibly related to capivasertib treatment. INTERPRETATION Updated FAKTION data showed that capivasertib addition to fulvestrant extends the survival of participants with aromatase inhibitor-resistant ER-positive, HER2-negative advanced breast cancer. The expanded biomarker testing suggested that capivasertib predominantly benefits patients with PI3K/AKT/PTEN pathway-altered tumours. Phase 3 data are needed to substantiate the results, including in patients with previous CDK4/6 inhibitor exposure who were not included in the FAKTION trial.

Abstract
Background Currently, there is no US Food and Drug Administration approved therapy for patients with pleural mesothelioma who have relapsed following platinum-doublet based chemotherapy. Vinorelbine has demonstrated useful clinical activity in mesothelioma, however its efficacy has not been formally evaluated in a randomised setting. BRCA1 expression is required for vinorelbine induced apoptosis in preclinical models. Loss of expression may therefore correlate with vinorelbine resistance. Methods In this randomised, phase 2 trial, patients were eligible if they met the following criteria: age ≥ 18 years, Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1, histologically confirmed pleural mesothelioma, post platinum-based chemotherapy, and radiological evidence of disease progression. Consented patients were randomised 2:1 to either active symptom control with oral vinorelbine versus active symptom control (ASC) every 3 weeks until disease progression, unacceptable toxicity or withdrawal at an initial dose of 60 mg/m2 increasing to 80 mg/m2 post-cycle 1. Randomisation was stratified by histological subtype, white cell count, gender, ECOG performance status and best response during first-line therapy. The study was open label. The primary endpoint was progression-free survival (PFS), measured from randomisation to time of event (or censoring). Analyses were carried out according to intention-to-treat (ITT) principles. Recruitment and trial follow-up are complete. This trial is registered with ClinicalTrials.gov, number NCT02139904. Findings Between June 1, 2016 and Oct 31, 2018, we performed a randomised phase 2 trial in 14 hospitals in the United Kingdom. 225 patients were screened for eligibility, of whom 154 were randomly assigned to receive either ASC + vinorelbine (n = 98) or ASC (n = 56). PFS was significantly longer for ASC+vinorelbine compared with ASC alone; 4.2 months (interquartile range (IQR) 2.2-8.0) versus 2.8 months (IQR 1.4-4.1) for ASC, giving an unadjusted hazard ratio (HR) of 0·60 (80% CI upper limit 0.7, one-sided unadjusted log rank test p = 0.002); adjusted HR 0.6 (80% CI upper limit 0.7, one-sided adjusted log rank test p < 0.001). BRCA1 did not predict resistance to ASC+vinorelbine. Neutropenia was the most common grades 3, 4 adverse events in the ASC +vinorelbine arm. Interpretation Vinorelbine plus ASC confers clinical benefit to patients with relapsed pleural mesothelioma who have progressed following platinum-based doublet chemotherapy. Funding This study was funded by Cancer Research UK (grant CRUK A15569).

Abstract
OBJECTIVES To assess the efficacy and tolerability of the dual epidermal growth factor receptor/vascular endothelial growth factor receptor inhibitor, vandetanib, in combination with carboplatin and gemcitabine in the first-line treatment of patients with advanced transitional cell carcinoma urothelial cancer (UC) who were unsuitable for cisplatin. PATIENTS AND METHODS From 2011 to 2014, 82 patients were randomised from 16 hospitals across the UK into the TOUCAN double-blind, placebo-controlled randomised Phase II trial, receiving six 21-day cycles of intravenous carboplatin (target area under the concentration versus time curve 4.5, day 1) and gemcitabine (1000 mg/m2 days 1 and 8) combined with either oral vandetanib 100 mg or placebo (once daily). Progression-free survival (PFS; primary endpoint), adverse events, tolerability and feasibility of use, objective response rate and overall survival (OS) were evaluated. Intention-to-treat and per-protocol analyses were used to analyse the primary endpoint. RESULTS The 82 patients were randomised 1:1 to vandetanib (n = 40) or placebo (n = 42), and 25 patients (30%) completed six cycles of all allocated treatment. Toxicity Grade ≥3 was experienced in 80% (n = 32) and 76% (n = 32) of patients in the vandetanib and placebo arms, respectively. The median PFS was 6.8 and 8.8 months for the vandetanib and placebo arms, respectively (hazard ratio [HR] 1.07, 95% confidence interval [CI] 0.65-1.76; P = 0.71); the median OS was 10.8 vs 13.8 months (HR 1.41, 95% CI 0.79-2.52; P = 0.88); and radiological response rates were 50% and 55%. CONCLUSION There is no evidence that vandetanib improves clinical outcome in this setting. Our present data do not support its adoption as the regimen of choice for first-line treatment in patients with UC who were unfit for cisplatin.

Abstract
BACKGROUND Capivasertib (AZD5363) is a potent selective oral inhibitor of all three isoforms of the serine/threonine kinase AKT. The FAKTION trial investigated whether the addition of capivasertib to fulvestrant improved progression-free survival in patients with aromatase inhibitor-resistant advanced breast cancer. METHODS In this randomised, double-blind, placebo-controlled, phase 2 trial, postmenopausal women aged at least 18 years with an Eastern Cooperative Oncology Group performance status of 0-2 and oestrogen receptor-positive, HER2-negative, metastatic or locally advanced inoperable breast cancer who had relapsed or progressed on an aromatase inhibitor were recruited from 19 hospitals in the UK. Enrolled participants were randomly assigned (1:1) to receive intramuscular fulvestrant 500 mg (day 1) every 28 days (plus a loading dose on day 15 of cycle 1) with either capivasertib 400 mg or matching placebo, orally twice daily on an intermittent weekly schedule of 4 days on and 3 days off (starting on cycle 1 day 15) until disease progression, unacceptable toxicity, loss to follow-up, or withdrawal of consent. Treatment allocation was done using an interactive web-response system using a minimisation method (with a 20% random element) and the following minimisation factors: measurable or non-measurable disease, primary or secondary aromatase inhibitor resistance, PIK3CA status, and PTEN status. The primary endpoint was progression-free survival with a one-sided alpha of 0·20. Analyses were done by intention to treat. Recruitment is complete, and the trial is in follow-up. This trial is registered with ClinicalTrials.gov, number NCT01992952. FINDINGS Between March 16, 2015, and March 6, 2018, 183 patients were screened for eligibility, of whom 140 (76%) were eligible and were randomly assigned to receive fulvestrant plus capivasertib (n=69) or fulvestrant plus placebo (n=71). Median follow-up for progression-free survival was 4·9 months (IQR 1·6-11·6). At the time of primary analysis for progression-free survival (Jan 30, 2019), 112 progression-free survival events had occurred, 49 (71%) in 69 patients in the capivasertib group compared with 63 (89%) of 71 in the placebo group. Median progression-free survival was 10·3 months (95% CI 5·0-13·2) in the capivasertib group versus 4·8 months (3·1-7·7) in the placebo group, giving an unadjusted hazard ratio (HR) of 0·58 (95% CI 0·39-0·84) in favour of the capivasertib group (two-sided p=0·0044; one-sided log rank test p=0·0018). The most common grade 3-4 adverse events were hypertension (22 [32%] of 69 patients in the capivasertib group vs 17 [24%] of 71 in the placebo group), diarrhoea (ten [14%] vs three [4%]), rash (14 [20%] vs 0), infection (four [6%] vs two [3%]), and fatigue (one [1%] vs three [4%]). Serious adverse reactions occurred only in the capivasertib group, and were acute kidney injury (two), diarrhoea (three), rash (two), hyperglycaemia (one), loss of consciousness (one), sepsis (one), and vomiting (one). One death, due to atypical pulmonary infection, was assessed as possibly related to capivasertib treatment. One further death in the capivasertib group had an unknown cause; all remaining deaths in both groups (19 in the capivasertib group and 31 in the placebo group) were disease related. INTERPRETATION Progression-free survival was significantly longer in participants who received capivasertib than in those who received placebo. The combination of capivasertib and fulvestrant warrants further investigation in phase 3 trials. FUNDING AstraZeneca and Cancer Research UK.

Abstract
Hepatocyte transplantation is a potential therapy for both acute and chronic hepatic insufficiency and also for treatment of inborn errors of metabolism affecting the liver. The peritoneum is one site for implantation and has several advantages: cells implanted there can be easily identified and observed, and it has a relatively large capacity. Long-term survival using “pure” hepatocytes in the peritoneum have been disappointing. We hypothesized that cotransplantation of hepatocytes with nonparenchymal cells would help maintain differentiated hepatocyte function. Rat liver cells transplanted intraperitoneally into August rats were sacrificed at 7 days, 1, 3, 6, 9, and 12 months and analyzed for presence, basal proliferation, and functionality of hepatocytes. To demonstrate that ectopic hepatocytes remained susceptible to exogenous growth factors affecting cell proliferation, rats 9 and 12 months after transplantation were stimulated with tri-iodothyronine and KGF. Hepatocytes were identified 7 days to >12 months, by H&E and immunohistochemically, as ectopic islands in the omental fat. Functionality was confirmed by glycogen deposition. Basal proliferation in 7-day rats was 28.0 ± 10/1000 hepatocytes in ectopic islands (cf. 5.70 ± 2.7/1000 in recipient liver). Proliferation in ectopic islands was greater than host liver. Growth factor-stimulated proliferation in ectopic islands induced a 70-fold increase in DNA synthesis. In conclusion, hepatocytes transplanted with nonparenchymal cells survive, proliferate, and function in the peritoneum of normal rats, and respond to exogenous growth stimuli. Their survival and proliferation in the presence of a normal functioning liver has implications for the potential use of the peritoneal site clinically for supplementation of liver function in metabolic disorders.

Abstract
BACKGROUND In a non-inferiority (NI) trial, analysis based on the intention-to-treat (ITT) principle is anti-conservative, so current guidelines recommend analysing on a per-protocol (PP) population in addition. However, PP analysis relies on the often implausible assumption of no confounders. Randomisation-based efficacy estimators (RBEEs) allow for treatment non-adherence while maintaining a comparison of randomised groups. Fischer et al. have developed an approach for estimating RBEEs in randomised trials with two active treatments, a common feature of NI trials. The aim of this paper was to demonstrate the use of RBEEs in NI trials using this approach, and to appraise the feasibility of these estimators as the primary analysis in NI trials. METHODS Two NI trials were used. One comparing two different dosing regimens for the maintenance of remission in people with ulcerative colitis (CODA), and the other comparing an orally administered treatment to an intravenously administered treatment in preventing skeletal-related events in patients with bone metastases from breast cancer (ZICE). Variables that predicted adherence in each of the trial arms, and were also independent of outcome, were sought in each of the studies. Structural mean models (SMMs) were fitted that conditioned on these variables, and the point estimates and confidence intervals compared to that found in the corresponding ITT and PP analyses. RESULTS In the CODA study, no variables were found that differentially predicted treatment adherence while remaining independent of outcome. The SMM, using standard methodology, moved the point estimate closer to 0 (no difference between arms) compared to the ITT and PP analyses, but the confidence interval was still within the NI margin, indicating that the conclusions drawn would remain the same. In the ZICE study, cognitive functioning as measured by the corresponding domain of the QLQ-C30, and use of chemotherapy at baseline were both differentially associated with adherence while remaining independent of outcome. However, while the SMM again moved the point estimate closer to 0, the confidence interval was wide, overlapping with any NI margin that could be justified. CONCLUSION Deriving RBEEs in NI trials with two active treatments can provide a randomisation-respecting estimate of treatment efficacy that accounts for treatment adherence, is straightforward to implement, but requires thorough planning during the design stage of the study to ensure that strong baseline predictors of treatment are captured. Extension of the approach to handle nonlinear outcome variables is also required. TRIAL REGISTRATION The CODA study: ClinicalTrials.gov, identifier: NCT00708656 . Registered on 8 April 2008. The ZICE study trial: ClinicalTrials.gov, identifier: NCT00326820 . Registered on 16 May 2006.

Abstract
BACKGROUND Surgical trials have typically experienced recruitment difficulties when compared with other types of oncology trials. Qualitative studies have an important role to play in exploring reasons for low recruitment, although to date few such studies have been carried out that are embedded in surgical trials. The BOLERO trial (Bladder cancer: Open versus Lapararoscopic or RObotic cystectomy) is a study to determine the feasibility of randomisation to open versus laparoscopic access/robotic cystectomy in patients with bladder cancer. We describe the results of a qualitative study embedded within the clinical trial that explored why patients decline randomisation. METHODS Ten semi-structured interviews with patients who declined randomisation to the clinical trial, and two interviews with recruiting research nurses were conducted. Data were analysed for key themes. RESULTS The majority of patients declined the trial because they had preferences for a particular treatment arm, and in usual practice could choose which surgical method they would be given. In most cases the robotic option was preferred. Patients described an intuitive 'sense' that favoured the new technology and had carried out their own inquiries, including Internet research and talking with previous patients and friends and family with medical backgrounds. Medical histories and lifestyle considerations also shaped these personalised choices. Of importance too, however, were the messages patients perceived from their clinical encounters. Whilst some patients felt their surgeon favoured the robotic option, others interpreted 'indirect' cues such as the 'established' reputation of the surgeon and surgical method and comments made during clinical assessments. Many patients expressed a wish for greater direction from their surgeon when making these decisions. CONCLUSION For trials where the 'new technology' is available to patients, there will likely be difficulties with recruitment. Greater attention could be paid to how messages about treatment options and the trial are conveyed across the whole clinical setting. However, if it is too difficult to challenge such messages, then questions should be asked about whether genuine and convincing equipoise can be presented and perceived in such trials. This calls for consideration of whether alternative methods of generating evidence could be used when evaluating surgical techniques which are established and routinely available.

Abstract
BACKGROUND Venous thromboembolism is common in cancer patients and requires anticoagulation with low-molecular-weight heparin (LMWH). Current data recommend LMWH for anticoagulation as far as 6 months, yet guidelines recommend LMWH beyond 6 months in patients who have ongoing or active cancer. This recommendation, based on expert consensus, has not been evaluated in a clinical study. OBJECTIVES (1) To identify the most clinically and cost-effective length of anticoagulation with LMWH in the treatment of cancer-associated thrombosis (CAT); (2) to identify practicalities of conducting a full randomised controlled trial (RCT) with regard to recruitment, retention and outcome measurement; and (3) to explore the barriers for progressing to a full RCT. DESIGN The Anticoagulation with Low-molecular-weight heparin In the treatment of Cancer-Associated Thrombosis (ALICAT) trial is a randomised, multicentre, feasibility mixed-methods study with three components: (1) a RCT comparing ongoing LMWH treatment for CAT with cessation of LMWH at 6 months' treatment (current licensed practice) in patients with locally advanced or metastatic cancer, consulted in three clinical settings (haematology outpatients, oncology outpatients and primary care); (2) a nested qualitative study, including focus groups with clinicians to investigate attitudes for recruiting to the study and identify the challenges of progressing to a full RCT, and semistructured interviews with patients and relatives to explore their attitudes towards participating in the study, and potential barriers and concerns to participation; and (3) a UK-wide survey exercise to develop a classification and enumeration system for the CAT models and pathways of care. SETTING A haematology outpatients department, an oncology outpatients department and primary care. PARTICIPANTS Patients with ongoing active or metastatic cancer who have received 6 months of LMWH for CAT. INTERVENTIONS Ongoing LMWH treatment for CAT versus cessation of LMWH at 6 months' treatment in patients with locally advanced or metastatic cancer. MAIN OUTCOME MEASURES (i) The number of eligible patients over 12 months; (ii) the number of recruited patients over 12 months (target recruitment rate of 30% of eligible patients); and (iii) the proportion of randomised participants with recurrent venous thromboembolisms (VTEs) during follow-up. RESULTS Following several delays in setting up the RCT component of the study, 5 out of 32 eligible patients consented to be randomised to the RCT suggesting progression to a full RCT was not feasible. Reasons for non-consenting were primarily based on a fixed preference for continuing or discontinuing treatment after 6 months of anticoagulation, and a fear of randomisation to their non-preferred option. Views were largely influenced by patients' initial experience of CAT. Focus groups with clinicians revealed that they would be reticent to recruit to such a study as they had fixed views of best management despite the lack of evidence. Patient pathway modelling suggested that there is a broad heterogeneity of practice with respect to CAT management and co-ordination, with no consensus on which specialty should best manage such cases. CONCLUSIONS The results of the RCT reflect recruitment from the oncology site only and provide no recruitment data from haematology centres. However, it is unlikely that these other sites would have access to more eligible patients. The management of cancer-associated thrombosis beyond 6 months will remain a clinical challenge. As it is unlikely that a prospective study will successfully recruit, other strategies to accrue relevant data are necessary. Currently the LONGHEVA (Long-term treatment for cancer patients with deep-venous thrombosis or pulmonary embolism) registry is in development to prospectively evaluate this important and common clinical scenario. STUDY REGISTRATION This study is registered as clinical trials.gov number NCT01817257 and International Standard Randomised Controlled Trial Number (ISRCTN) 37913976. FUNDING DETAILS Funding for the ALICAT trial was provided by the Health Technology Assessment programme (10/145/01) in response to a themed funding call. The study was designed in accordance with the initial funding brief and feedback from the review process.

Abstract
UNLABELLED Gemcitabine and cisplatin chemotherapy (GC regimen) represents a standard treatment for advanced urothelial carcinoma. We performed an open-label, single-arm, non-randomised, phase 2 trial evaluating the addition of sunitinib to standard GC chemotherapy (SGC regimen). Overall, 63 treatment-naïve participants were recruited and received up to six 21-d cycles of cisplatin 70 mg/m2 (intravenously [IV], day 1) and gemcitabine 1000 mg/m2 (IV, days 1 and 8) combined with sunitinib 37.5 mg (orally, days 2-15). Following review of toxicity after the first six patients, the sunitinib dose was reduced to 25 mg for all patients. Overall response rate was 64%, with response noted in 37 of 58 patients. At 6 mo, 30 of 58 assessable patients (52%; 90% confidence interval [CI], 40-63%) were progression free. Median overall survival was 12 mo (95% CI, 9-15) and was heavily influenced by Bajorin prognostic group. Grade 3-4 toxicities were predominantly haematologic and limited the deliverability of the triple SGC regimen. The trial did not meet its prespecified primary end point of >60% patients progression free at 6 mo. Cumulative myelosuppression led to treatment delays of gemcitabine and cisplatin and dose reduction and/or withdrawal of sunitinib in the majority of cases. The triple-drug combination was not well tolerated. Phase 3 evaluation of the triple SGC regimen in advanced transitional cell carcinoma is not recommended. PATIENT SUMMARY The addition of sunitinib to standard cisplatin and gemcitabine chemotherapy was poorly tolerated and did not improve outcomes in advanced urothelial carcinoma. Treatment delivery was limited by myelotoxicity.

This recommendation, based on expert consensus, has not been evaluated in a clinical study. ALICAT (Anticoagulation Length in Cancer Associated Thrombosis) is a feasibility study to identify the most clinically and cost effective length of anticoagulation with low molecular weight heparin in the treatment of cancer associated thrombosis. METHODS/DESIGN ALICAT is a randomized multi-centre phase two mixed-methods study with three components: a randomized controlled trial, embedded qualitative study and a survey investigating pathways of care. The randomized controlled trial will compare ongoing low molecular weight heparin treatment for cancer-associated thrombosis versus cessation of low molecular weight heparin at six months treatment (current licensed practice) in patients with locally advanced or metastatic cancer. The embedded qualitative study will include focus groups with clinicians to investigate attitudes to recruiting to the study, identify the challenges of progressing to a full randomized controlled trial, and also semi-structured interviews with patients and relatives/carers to explore their attitudes towards participating in the study and potential barriers and concerns to participation. Finally, a UK wide survey exercise will be undertaken to develop a classification and enumeration system for the cancer associated thrombosis models and pathways of care. DISCUSSION There is a lack of evidence determining the length of anticoagulation for patients with cancer associated thrombosis and subsequently treatment length varies. The ALICAT study will consider the feasibility of recruiting patients to a phase three trial. TRIAL REGISTRATION Current Controlled Trials ISRCTN37913976.

Abstract
BACKGROUND Bisphosphonates are routinely used in the treatment of metastatic bone disease from breast cancer to reduce pain and bone destruction. Zoledronic acid given by intravenous infusion has been widely used, but places a substantial logistical burden on both patient and hospital. As a result, the use of oral ibandronic acid has increased, despite the absence of comparative data. In the ZICE trial, we compared oral ibandronic acid with intravenous zoledronic acid for the treatment of metastatic breast cancer to bone. METHODS This phase 3, open-label, parallel group active-controlled, multicentre, randomised, non-inferiority phase 3 study was done in 99 UK hospitals. Eligibility criteria included at least one radiologically confirmed bone metastasis from a histologically confirmed breast cancer. Patients with ECOG performance status 0 to 2 and clinical decision to treat with bisphosphonates within 3 months of randomisation were randomly assigned to receive 96 weeks of treatment with either intravenous zoledronic acid at 4 mg every 3-4 weeks or oral ibandronic acid 50 mg daily. Randomisation (1:1) was done via a central computerised system within stratified block sizes of four. Randomisation was stratified on whether patients had current or planned treatment with chemotherapy; current or planned treatment with hormone therapy; and whether they had a previous skeletal-related event within the last 3 months or had planned radiotherapy treatment to the bone or planned orthopaedic surgery due to bone metastases. The primary non-inferiority endpoint was the frequency and timing of skeletal-related events over 96 weeks, analysed using a per-protocol analysis. All active (non-withdrawn) patients have now reached the 96-week timepoint and the trial is now in long-term follow-up. The trial is registered with ClinicalTrials.gov, number NCT00326820. FINDINGS Between Jan 13, 2006, and Oct 4, 2010, 705 patients were randomly assigned to receive ibandronic acid and 699 to receive zoledronic acid; three patients withdrew immediately after randomisation. The per-protocol analysis included 654 patients in the ibandronic acid group and 672 in the zoledronic acid group. Annual rates of skeletal-related events were 0·499 (95% CI 0·454-0·549) with ibandronic acid and 0·435 (0·393-0·480) with zoledronic acid; the rate ratio for skeletal-related events was 1·148 (95% CI 0·967-1·362). The upper CI was greater than the margin of non-inferiority of 1·08; therefore, we could not reject the null hypothesis that ibandronic acid was inferior to zoledronic acid. More patients in the zoledronic acid group had renal toxic effects than in the ibandronic acid group (226 [32%] of 697 vs 172 [24%] of 704) but rates of osteonecrosis of the jaw were low in both groups (nine [1%] of 697 vs five [<1%] of 704). The most common grade 3 or 4 adverse events were fatigue (97 [14%] of 697 patients allocated zoledronic acid vs 98 [14%] of 704 allocated ibandronic acid), increased bone pain (91 [corrected] [13%] vs 85 [corrected] [12%]), joint pain (41 [corrected] [6%] vs 38 [5%]), infection (31 [5%] vs 23 [corrected] [3%]), and nausea or vomiting (38 [5%] vs 41 [6%]). INTERPRETATION Our results suggest that zoledronic acid is preferable to ibandronic acid in preventing skeletal-related events caused by bone metastases. However, both drugs have acceptable side-effect profiles and the oral formulation is more convenient, and could still be considered if the patient has a strong preference or if difficulties occur with intravenous infusions.

Abstract
Abstract
Introduction Bone metastases in patients with breast cancer have serious effects on health including pain, poor mobility, skeletal fractures, spinal cord compression and the need for radiotherapy/surgery. The introduction of intravenous (IV) bisphosphonates, such as zoledronic acid (Z) has significantly delayed the onset of skeletal-related events (SRE). However, prolonged IV bisphosphonates place burdens upon patient and hospital, and can also cause renal and acute phase toxicities. Ibandronic acid (I), a third generation amino-bisphosphonate in its oral form has previously been compared with placebo and was shown to be well tolerated and effective. Indirect comparisons with IV Z indicated similar efficacy in reducing bone events, but adverse events were overall comparable with placebo. One might therefore assume that oral ibandronate would be more acceptable to patients, and the ZICE Trial is the only large scale direct randomised comparison between IV Z and oral I to report.
Methods Between January 2006 and October 2010, 1405 newly diagnosed metastatic breast cancer patients with proven bone metastases were randomised 1:1 to IV Z (4mg 15 min infusion every 3–4 weeks) or oral I (50mg per day) for up to 96 weeks. All patients were prescribed daily calcium & vitamin D supplementation, and patients with current active dental problems including infection were excluded. Patients also received chemotherapy, and or endocrine therapy as determined by their physician. The primary objective was to demonstrate non-inferiority of oral I in comparison with IV Z in terms of the SRE rate, defined as the number of SREs reported per year (using multiple event analysis). Secondary endpoints included time to 1st SRE, proportion of patients with SRE, Pain Scores, side effect profiles including ONJ and renal toxicities, quality of life and Health resources and overall survival. The trial was run under the auspices of the NCRI, sponsored by Velindre NHS Trust, coordinated by the Wales Cancer Trials Unit, funded by an educational grant from Roche and peer reviewed/endorsed by Cancer Research UK (CRUKE/04/022).
Results At the time of this analysis the last randomised patient had completed 96 weeks of therapy, median follow up was 18.4 months and total number of SREs was 865 (468 in I and 397 in Z). For the primary objective, the SRE rate was 0.543 and 0.444 in I and Z groups respectively (Hazard ratio, 1.22; 95% CI, 1.04 to 1.45; P = .017). Ibandronate failed to meet the criteria for non-inferiority to Zoledronate, but was similar in delaying time to first SRE (hazard ratio, 1.11; 95% CI, 0.94 to 1.31; P = .233). Overall survival (disease progression), was very similar between groups but renal AEs occurred more frequently with Z than I; Compliance with oral therapy was 82%. ONJ rate was very low in both arms (0.71%, I; 1.29%, Z; P = 0.28).
Conclusion Oral I is inferior to Z in terms of the SRE rate in metastatic breast cancer patients with bone metastases, but is similar to Z in delaying time to first SRE. Both drugs had acceptable safety profiles, with adverse events consistent with those reported previously.

Abstract
We evaluated hypoxia inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) expression and their prognostic significance in diffuse large B-cell lymphoma (DLBCL). Expression of HIF-1α and VEGF was studied in 78 patients and results correlated with clinicopathological and prognostic data. HIF-1α and VEGF were expressed in 67% and 84% of patients, respectively, and a significant correlation was demonstrated between them (p < 0.001). Outcome was analyzed according to treatment. HIF-1α positive patients given rituximab demonstrated improved outcome, with 5-year overall survival of 72% for those receiving rituximab versus 65% for those not receiving rituximab, and 5-year progression-free survival (PFS) 76% versus 57%. No correlation was demonstrated between HIF-1α and other prognostic biomarkers including BCL6, CD10 and MUM-1. We demonstrated significantly improved PFS (p = 0.003) in patients receiving rituximab and showing BCL6 overexpression. The results confirm the significant association between HIF-1α and VEGF expression and suggest that HIF-1α expression is a favorable prognostic factor in patients with DLBCL treated with rituximab.

Abstract
BACKGROUND Definitive chemoradiotherapy (dCRT) has been proposed as an alternative therapy for selected patients with oesophageal cancer. The aim of this study was to determine the outcomes of dCRT, surgery alone, and neoadjuvant chemotherapy followed by surgery (CS) in patients with oesophageal cancer. METHODS Consecutive patients diagnosed with oesophageal cancer and managed by a multidisciplinary team were staged by computed tomography and endoluminal ultrasonography. Those deemed unsuitable for surgery on the grounds of performance status, bulky local disease or personal choice received dCRT. The primary outcome measure was overall survival measured from date of diagnosis. RESULTS Of 417 patients, 173 received dCRT, 126 underwent surgery alone and 118 received CS. The incidence of grade III/IV toxicity after dCRT and CS was 39.3 and 60.2 per cent respectively. Operative morbidity rates were 42.9 and 44.4 per cent after surgery alone and CS respectively. Thirty-day mortality rates were zero, 7.9 and 0.8 per cent after dCRT, surgery alone and CS respectively. Overall 2-year survival rates were 44.3, 56.2 and 42.4 per cent (P = 0.422). CONCLUSION These findings support the need for a randomized trial of dCRT versus CS for resectable oesophageal cancer.

Abstract
OBJECTIVES To evaluate whether the additional information provided by minimally invasive glucose monitors results in improved glycaemic control in people with poorly controlled insulin-requiring diabetes, and to assess the acceptability and health economic impact of the devices. DESIGN A four-arm randomised controlled trial was undertaken. SETTING Participants were recruited from secondary care diabetes clinics in four hospitals in England. PARTICIPANTS 404 people aged over 18 years with insulin-treated diabetes mellitus (types 1 or 2) for at least 6 months who were receiving two or more injections of insulin daily were eligible. Participants had to have had two glycosylated haemoglobin (HbA1c) values > or = 7.5% in the last 15 months. INTERVENTIONS Participants were randomised to one of four groups. Two groups received minimally invasive glucose monitoring devices [GlucoWatch Biographer or MiniMed Continuous Glucose Monitoring System (CGMS)]. These groups were compared with an attention control group (standard treatment with nurse feedback sessions at the same frequency as those in the device groups) and a standard control group (reflecting common practice in the clinical management of diabetes in the UK). MAIN OUTCOME MEASURES Change in HbA1c from baseline to 3, 6, 12 and 18 months was the primary indicator of short- to long-term efficacy in this study. Perceived acceptability of the devices was assessed by use and a self-report questionnaire. A health economic analysis was also performed. RESULTS At 18 months all groups demonstrated a decline in HbA1c levels from baseline. Mean percentage changes in HbA1c were -1.4 for the GlucoWatch group, -4.2 for the CGMS group, -5.1 for the attention control group and -4.9 for the standard care control group. At 18 months the relative percentage reduction in HbA1c in each of the intervention arms was less than that in the standard care control group. In the intention to treat analysis no significant differences were found between any of the groups at any of the assessment times. There was no evidence that the additional information provided by the devices resulted in any change in the number or nature of treatment recommendations offered by the nurses. The health economics analysis indicated no advantage in the groups who received the devices; a lower cost and higher benefit were found for the attention control arm. Assessment of device use and acceptability indicated a decline in use of both devices, which was most marked in the GlucoWatch group by 18 months (20% still using GlucoWatch versus 57% still using the CGMS). The GlucoWatch group reported more side effects, greater interference with daily activities and more difficulty in using the device than the CGMS group. CONCLUSIONS Continuous glucose monitors do not lead to improved clinical outcomes and are not cost-effective for improving HbA1c in unselected individuals with poorly controlled insulin-requiring diabetes. On acceptability grounds the data suggest that the GlucoWatch will not be frequently used by individuals with diabetes because of the large number of side effects.

Abstract
AIMS To determine whether continuous glucose information provided through use of either the GlucoWatch G2 Biographer or the MiniMed continuous glucose monitoring system (CGMS) results in improved glycated haemoglobin (HbA(1c)) for insulin-treated adults with diabetes mellitus, relative to an attention control and standard care group. METHODS Four hundred and four adults taking at least two daily insulin injections and with two consecutive HbA(1c) values > or = 7.5% were recruited to this randomized controlled trial (RCT). All were trained at baseline to use the same monitor for traditional capillary glucose testing throughout the 18-month study. The CGMS group were asked to wear the device three times during the first 3 months of the trial and on another three occasions thereafter. The GlucoWatch group wore the device a minimum of four times per month and a maximum of four times per week during the first 3 months and as desired for the remainder of the trial. Trained diabetes research nurses used downloaded data to guide therapy adjustments. Proportional reduction in HbA(1c) from baseline to 18 months was the primary outcome measure. RESULTS Neither an intention-to-treat nor per-protocol analysis showed improvement in HbA(1c) in the device groups compared with standard care. For the intention-to-treat analysis, when the standard care group was compared with each of the other groups, this equated to differences in mean relative HbA(1c) reduction (95% confidence interval) from baseline to 18 months of 3.5% (-1.3 to 8.3; GlucoWatch), 0.7% (-4.1 to 5.5; CGMS), and -0.1% (-4.6 to 4.3; attention control). CONCLUSIONS The additional information provided by these devices did not result in improvements in HbA(1c) in this population.

Abstract
BACKGROUND The pathogenesis of posttransfusion purpura (PTP) and transfusion-associated graft-versus-host disease (TA-GVHD) involves patient exposure to donor platelets (PLTs) and T lymphocytes, respectively, which are removed during blood component leukodepletion (LD). STUDY DESIGN AND METHODS Reports of PTP and TA-GVHD to the UK hemovigilance scheme Serious Hazards of Transfusion (SHOT) from 1996 to 2005 were compared before and after implementation of universal LD during 1999. RESULTS There were 45 reports of PTP, with a mean of 10.3 per year before universal LD and 2.3 per year afterward (p < 0.001). All patients had received red cells, but before universal LD, only 1 of 31 (3%) cases had also received PLTs, compared to 8 of 14 (57%) afterward (p < 0.001). Thirty-four cases (76%) had human platelet antigen (HPA)-1a antibodies, whereas 11 had antibodies to other HPA specificities, only 1 of which occurred after LD. Two cases reported before LD also had heparin-dependent PLT antibodies. There were 13 reports of TA-GVHD, all fatal, of which only 2 cases of undiagnosed immunodeficiency met current UK criteria for irradiated components. Eight others had one or more risk factors: B-cell malignancy (6), steroids (1), fresh blood (1), and donor-recipient HLA haplotype share (4). Eleven cases were due to non-LD and 2 to LD components (p < 0.001). No cases have been reported since 2001. In an additional 405 cases, nonirradiated components were transfused in error to high-risk recipients, mainly on fludarabine, but none developed TA-GVHD. CONCLUSIONS These findings suggest that universal LD has further reduced the already low risk of TA-GVHD in immunocompetent recipients and has altered the profile of PTP cases.

Abstract
BACKGROUND The antenatal management of fetomaternal alloimmune thrombocytopenia (FMAIT) due to HPA-1a antibodies remains controversial, and a test identifying pregnancies that do not require therapy would be of clinical value. STUDY DESIGN AND METHODS The statistical correlation was analyzed between clinical outcome and 1) anti-HPA-1a potency in maternal serum samples determined by a monoclonal antibody immobilization of platelet (PLT) antigen assay with an international anti-HPA-1a potency standard and 2) anti-HPA-1a biological activity measured by a monocyte chemiluminescence (CL) assay. RESULTS A total of 133 pregnancies with FMAIT due to anti-HPA-1a were analyzed. In 97 newly diagnosed cases, there was no difference in antibody potency or CL signal between cases with intracranial hemorrhage (ICH; n = 15), those with no ICH but a PLT count of less than 20 x 10(9) per L (n = 52), and those with a PLT count of at least 20 x 10(9) per L (n = 30). In 22 previously known pregnancies, the positive predictive value of maternal anti-HPA-1a of greater than 30 IU per mL for a PLT count of less than 20 x 10(9) per L was 90 percent, but the negative predictive value was only 66 percent. Antibody potency tended to stay stable throughout pregnancy (n = 16) and from one pregnancy to the next (n = 16). CONCLUSION Neither severe thrombocytopenia nor ICH in HPA-1a-alloimmunized pregnancies can be predicted with sufficient sensitivity and specificity for clinical application from maternal anti-HPA-1a potency or bioactivity.

Abstract
BACKGROUND AND OBJECTIVES The aim of this study was to evaluate the collection of daily prospective information about bleeding outcomes in patients with thrombocytopenia, including information obtained by patient self-assessment. MATERIALS AND METHODS Consecutive patients with haematological malignancies were enrolled in a study of bleeding data collection during the period of thrombocytopenia. A short educational session and information sheet was designed for self-assessment. Platelet counts and all transfusions were recorded daily. Bleeding scores were translated into World Health Organization (WHO) bleeding grades. RESULTS Nineteen patients were included in the study. Four-hundred and ten days of thrombocytopenia were eligible for assessment of bleeds. Self-assessment was feasible, as defined by the total proportion of days on which self-assessment was completed (70%, 288 thrombocytopenic days). There was 86% agreement between bleeding data collected by self-assessment and by medical examination using a structured assessment form. Examples of discrepancies included the duration of petechiae/bruises and the reporting of minor bleeding. There was no evidence for an association between patients' morning platelet count and daily WHO bleeding grade. The incidences of WHO grade 1 and grade 2 bleeding on days with platelet counts < or = 10 x 10(9)/l, 11-20 x 10(9)/l, and > 20 x 10(9)/l were similar and did not reveal higher rates of bleeding at lower counts. CONCLUSIONS Patient self-assessment can help to support comprehensive daily prospective monitoring of bleeding, specifically facilitating data collection following hospital discharge. The discrepancies between self-assessment and medical examination highlight the need to develop a validated international assessment tool. The association among platelet count, risk of bleeding and role of prophylactic platelet transfusions needs further evaluation in larger prospective trials.

Abstract
BACKGROUND Incorrect blood component transfused is a frequent serious incident associated with transfusion and often involves misidentification of the patient and/or the unit of blood. STUDY DESIGN AND METHODS This study extended the evaluation of an electronic system involving bar code technology and handheld computers. Electronic control of collection of blood from blood refrigerators was incorporated into a previously described process for blood sample collection and blood administration. Practice was evaluated before and after its introduction in cardiac surgery. RESULTS The baseline audits revealed poor practice. Significant improvements were found following the introduction of the electronic system, including from 8 percent to 100 percent in checking that the blood group and unit number on the blood pack matched the compatibility label and the pack was in date (p < or = 0.0001). Similar significant improvements were found in blood sample collection, the collection of blood from blood refrigerators, and the documentation of transfusion. Staff found the system easy to operate and preferred it to standard procedures. CONCLUSIONS A bar code patient identification system improved transfusion practice, although areas for improvement were identified. These results provide support for further work on the development of such systems for both transfusion and other procedures requiring patient identification.

Abstract
BACKGROUND AND OBJECTIVES Red cell transfusion is commonly used in orthopaedic surgery. Evidence suggests that a restrictive transfusion strategy may be safe for most patients. However, concern has been raised over the risks of anaemia in those with ischaemic cardiac disease. Perioperative silent myocardial ischaemia (SMI) has a relatively high incidence in the elderly population undergoing elective surgery. This study used Holter monitoring to compare the effect of a restrictive and a liberal red cell transfusion strategy on the incidence of SMI in patients without signs or symptoms of ischaemic heart disease who were undergoing lower limb arthroplasty. MATERIALS AND METHODS We performed a multicentre, controlled trial in which 260 patients undergoing elective hip and knee replacement surgery were enrolled and randomized to transfusion triggers that were either restrictive (8 g/dl) or liberal (10 g/dl). Participants were monitored with continuous ambulatory electrocardiogram (ECG) (Holter monitoring), preoperatively for 12 h and postoperatively for 72 h. The tapes were analysed for new ischaemia by technicians blinded to treatment. The total ischaemia time in minutes was divided by the recording time in hours and an ischaemic load in min/h was calculated. Haemoglobin levels were measured preoperatively, postoperatively in the recovery room, and on days one, three and five after surgery. RESULTS The mean postoperative haemoglobin concentration was 9.87 g/dl in the restrictive group and 11.09 g/dl in the liberal group. In the restrictive group, 34% were transfused a total of 89 red cell units, and in the liberal group 43% were given a total of 119 red cell units. A postoperative episode of silent ischaemia was experienced by 21/109 (19%) patients in the restrictive group and by 26/109 (24%) patients in the liberal group [mean difference -4.6%; 95% confidence interval (CI): -15.5% to 6%, P = 0.41). There was no significant difference (P = 0.53) between the overall ischaemic load in the restrictive group (median 0 min/h, range 0-4.18) and the liberal group (median 0 min/h, range 0-19.48). In those patients who did experience postoperative SMI, the mean ischaemic load was 0.48 min/h in the restrictive group and 1.51 min/h in the liberal group (ratio 0.32, 95% CI: 0.14-0.76, P = 0.011). The median postoperative length of hospital stay in the restrictive group was 7.3 days [range 5-11; interquartile range (IQR) 6-8] compared with 7.5 days (range 5-13; IQR 7-8) in the liberal group. The numbers were not large enough to conclude equivalence. CONCLUSIONS In patients without preoperative evidence of myocardial ischaemia undergoing elective hip and knee replacement surgery, a restrictive transfusion strategy seems unlikely to be associated with an increased incidence of SMI. A proportion of these patients experience moderate SMI, regardless of the transfusion trigger. Use of a restrictive transfusion strategy did not increase length of hospital stay, and use of this strategy would lead to a significant reduction in red cell transfusion in orthopaedic surgery. Our data did not indicate any potential for harm in employing such a strategy in patients with no prior evidence of cardiac ischaemia who were undergoing elective orthopaedic surgery.

Abstract
OBJECTIVES To gather data on current preoperative transfusion practice and postoperative complications in sickle cell disease (SCD) as a prelude to a randomised trial. METHODS A prospective one year survey of 114 SCD patients undergoing elective surgery in 31 English hospitals was undertaken. RESULTS 43%, 39% and 23% of patients respectively [corrected] received no transfusion, top-up and exchange transfusion preoperatively. Overall postoperative complication rates were 18%, 26% and 17%, with SCD related complications of 12%, 8% and 0% respectively. 85% of patients with [corrected]HbSC/HbSss(+)thalassaemia and 71% of obstetric and gynaecology patients were not transfused preoperatively, whereas 59% patients undergoing ENT procedures and 83% of hip replacements had top-up and exchange transfusions respectively. Multivariable logistic regression analysis revealed that having moderate/high risk procedures was a predictor of postoperative complications (OR 4.9 (95% CL: 1.3 to 18), P = 0.017) [corrected] while preoperative transfusion was not (OR 1.7, (95% CL: [corrected] 0.5 to 6), P = 0.41). CONCLUSION The lack of clear benefit of transfusion confirms the need for a randomised controlled trial of transfusion vs. no transfusion in patients with HbSS and HbSss(0)thalassaemia.

Abstract
Although haematology analysers provide reliable full blood counts, they are known to be inaccurate at enumerating platelets in severe thrombocytopenia. If the thresholds for platelet transfusion, currently set at 10 x 10(9)/l, are to be further reduced, it is vital that the limitations of current analysers are fully understood. The aim of this large multicentre study was to determine the accuracy of haematology analysers in current routine practice for platelet counts below 20 x 10(9)/l. Platelet counts estimated by analysers using optical, impedance and immunological methods were compared with the International Reference Method for platelet counting. The results demonstrated variation in platelet counting between different analysers and even the same type of analyser at different sites. Optical methods for platelet counting on the XE 2100, Advia 120, Cell-Dyn 4000 and H3* were not superior to impedance methods on the XE 2100, LH750 and Pentra analysers. All analysers except one overestimated the platelet count, which would result in under transfusion of platelets. This study highlights the inaccuracies of haematology analysers in platelet counting in severe thrombocytopenia. It re-emphasizes the need for external quality control to improve analyser calibration for samples with low platelet counts, and suggests that the optimal thresholds for prophylactic platelet transfusions should be re-evaluated.

Abstract
BACKGROUND AND OBJECTIVES Ghana is one of the countries of sub-Saharan Africa where the human immunodeficiency virus (HIV) prevalence in blood donors ranges between 1 and 4%. Considering the social importance of religion and the very high level of religious practice observed in Ghana, the hypothesis that these factors may play a role in containing HIV was tested. MATERIALS AND METHODS Consenting HIV-infected candidate blood donors, and two age- and gender-matched seronegative control donors, were asked to complete a questionnaire regarding their religious and sexual behaviour. Multivariable conditional logistic regression was used. RESULTS Irrespective of their HIV status or religion, 95% of the respondents believed that extra-marital sex was a sin, and 79% of those tempted to have an extra-marital affair considered that their religious beliefs helped them to abstain. In the multivariable models, having a formal role in church activities was associated with reduced odds of HIV [odds ratio (OR) = 0.41; 95% confidence interval (CI): 0.21-0.80]. Worshipping at the same location for more than 20 years was associated with a reduced risk (OR = 0.30; 95% CI: 0.08-1.10). In addition to other factors limiting HIV spread, such as male circumcision, relatively high level of education and an absence of armed conflicts in Ghana, the use of condoms conferred a reduced risk. CONCLUSIONS An active role in religion, and reporting a lengthy duration of worship at the same place was beneficial. Collecting blood at places of worship with a strict behavioural code and from donors practicing in the community of their birth might improve blood safety.

Abstract
BACKGROUND Tuberculous pericarditis is common in Transkei (Eastern Cape). Two randomized trials showed benefits at two years for prednisolone in patients with constrictive pericarditis, and open drainage plus prednisolone in patients with pericardial effusion. AIM To see whether the advantages of prednisolone and open drainage were maintained up to 10 years. DESIGN Follow-up of randomized, double-blind, placebo-controlled trials. METHODS All 383 patients (143 constriction, 240 effusion) received the same anti-tuberculosis chemotherapy. They were randomized to prednisolone or placebo for the first 11 weeks, and were followed-up over 10 years. Among the 240 with effusion, 122 were also randomized to immediate open surgical drainage of pericardial fluid versus pericardiocentesis as required. Adverse outcomes were: death from pericarditis, pericardiectomy, repeat pericardiocentesis, and subsequent open drainage. RESULTS The 10-year follow-up rate was 96%. In constriction patients, adverse outcomes occurred in 19/70 (27%) prednisolone vs. 28/73 (38%) placebo (p = 0.15), deaths from pericarditis being 2 (3%) vs. 8 (11%), respectively (p = 0.098, Fisher's exact test). In effusion patients, adverse outcomes occurred in 14/27 (52%) with neither drainage nor prednisolone, vs. 4/29 (14%) drainage and prednisolone, 4/35 (11%) drainage and placebo, and 6/31 (19%) prednisolone and no drainage (p = 0.08 for interaction). Drainage eliminated the need for repeat pericardiocentesis. In the 176 with effusion and no drainage, adverse outcomes occurred in 17/88 (19%) prednisolone vs. 35/88 (40%) placebo patients (p = 0.003), with repeat pericardiocentesis 20 (23%) placebo vs. 9 (10%) prednisolone (p = 0.025). In a multivariate survival analysis (stratified by type of pericarditis), prednisolone reduced the overall death rate after adjusting for age and sex (p = 0.044), and substantially reduced the risk of death from pericarditis (p = 0.004). At 10 years, the great majority of surviving patients in all treatment groups were either fully active or out and about, even if activity was restricted. DISCUSSION In the absence of a clear contraindication, a corticosteroid should be used in addition to antituberculosis chemotherapy in the management of patients with tuberculous pericarditis.

Abstract
OBJECTIVES To model the determinants of serious operative and post-operative complications of hysterectomy and their potential risk factors. DESIGN A prospective cohort of women undergoing hysterectomies for benign indications in 1994/1995, with a six-week postsurgery follow up. POPULATION AND SETTING A total of 37,512 women from 276 NHS and 145 private hospitals in England, Wales and Northern Ireland, originally recruited to compare the outcomes of endometrial destruction with those of hysterectomy. METHODS Gynaecologists reported hysterectomies for non-malignant indications carried out during a 12-month period beginning in October 1994 and follow up data were obtained at outpatient follow up six weeks postsurgery. Odds ratios of severe complications by indication and method, adjusting for measured intrinsic risk factors, were calculated. MAIN OUTCOME MEASURES Severe operative and post-operative complications. RESULTS Severe operative complications occurred in 3%. The risk decreased with age and increased with greater parity and history of serious illness. Women with symptomatic fibroids (4.4%, 95% CI 3.9-4.9) experienced more complications than women with dysfunctional uterine bleeding (3.6%, 3.2-3.8), adjusted odds ratio (OR) = 1.3 (95% CI 1.1-1.6). Laparoscopic procedures (6.1%) doubled the risk of operative complications of abdominal hysterectomy (3.6%) (adjusted OR = 1.9, 1.5-2.5). Post-operative complications occurred in around 1% of women, with a slight decrease with increasing age, and the strongest risk factor was a history of operative complications. Relative to dysfunctional uterine bleeding (1.0%), a higher risk for fibroids (1.2%) persisted after adjustments (RR = 1.5, 1.1-2.0). Both vaginal (1.2%) and laparoscopic (1.7%) techniques had significantly higher adjusted risks than abdominal operations (0.9%), RR = 1.4 (1.0-1.9) and RR = 1.6 (1.0-2.7). There were no operative deaths; 14 women died within the six-week postsurgery (a crude mortality rate of 3.8/1000, 2.5-6.4). CONCLUSIONS Hysterectomy is a common, routine surgery with comparatively rare serious complications. However, younger women, women with more vascular pelvis, who undergo hysterectomy, especially laparoscopically assisted vaginal surgery for symptomatic fibroids, are at most risk of experiencing severe complications both operatively and post-operatively. Therefore, a less invasive alternative treatment for symptomatic fibroids could particularly benefit this group of women, while less invasive treatments for dysfunctional uterine bleeding, such as various methods of endometrial ablations or resections, would need to meet the current low levels of clinical complications in order to replace hysterectomy.

Abstract
Hepatocyte transplantation is a potential therapy for both acute and chronic hepatic insufficiency and also for treatment of inborn errors of metabolism affecting the liver. The peritoneum is one site for implantation and has several advantages: cells implanted there can be easily identified and observed, and it has a relatively large capacity. Long-term survival using "pure" hepatocytes in the peritoneum have been disappointing. We hypothesized that cotransplantation of hepatocytes with nonparenchymal cells would help maintain differentiated hepatocyte function. Rat liver cells transplanted intraperitoneally into August rats were sacrificed at 7 days, 1, 3, 6, 9, and 12 months and analyzed for presence, basal proliferation, and functionality of hepatocytes. To demonstrate that ectopic hepatocytes remained susceptible to exogenous growth factors affecting cell proliferation, rats 9 and 12 months after transplantation were stimulated with tri-iodothyronine and KGF. Hepatocytes were identified 7 days to >12 months, by H&E and immunohistochemically, as ectopic islands in the omental fat. Functionality was confirmed by glycogen deposition. Basal proliferation in 7-day rats was 28.0 +/- 10/1000 hepatocytes in ectopic islands (cf. 5.70 +/- 2.7/1000 in recipient liver). Proliferation in ectopic islands was greater than host liver. Growth factor-stimulated proliferation in ectopic islands induced a 70-fold increase in DNA synthesis. In conclusion, hepatocytes transplanted with nonparenchymal cells survive, proliferate, and function in the peritoneum of normal rats, and respond to exogenous growth stimuli. Their survival and proliferation in the presence of a normal functioning liver has implications for the potential use of the peritoneal site clinically for supplementation of liver function in metabolic disorders.

Abstract
OBJECTIVES To describe hysterectomies practised in 1994 and 1995: the patients, their surgery and short term outcomes. DESIGN One of two large cohorts, with prospective follow up, recruited to compare the outcomes of endometrial destruction with those of hysterectomy. SETTING England, Wales and Northern Ireland. POPULATION All women who had hysterectomies for non-malignant indications carried out during a 12-month period. METHODS Gynaecologists in NHS and independent hospitals were asked to report cases. Follow up data were obtained at outpatient follow up approximately six weeks post-surgery. MAIN OUTCOME MEASURES Indication for surgery, method of hysterectomy, ovarian status post-surgery, surgical complications. RESULTS 37,298 cases were reported which is estimated to reflect about 45% of hysterectomies performed during the period studied. The median age was 45 years, and the most common indication for surgery was dysfunctional uterine bleeding (46%). Most hysterectomies were carried out by consultants (55%). The proportions of women having abdominal, vaginal or laparoscopically-assisted hysterectomy were 67%, 30% and 3%, respectively. Forty-three percent of women had no ovaries conserved after surgery. The median length of stay was five days. The overall operative complication rate was 3.5%, and highest for the laparoscopic techniques. The overall post-operative complication rate was 9%. One percent of these was regarded as severe, with the highest rate for severe in the laparoscopic group (2%). There were no operative deaths; 14 deaths were reported within the six-week post-operative period: a crude mortality rate soon after surgery of 0.38 per thousand (95% CI 0.25-0.64). CONCLUSIONS This large study describes women who undergo hysterectomy in the UK, and presents results on early complications associated with the surgery. Operative complications occurred in one in 30 women, and post-operative complications in at least one in 10. Laparoscopic techniques tend to be associated with higher complication rates than other methods.
