Abstract
PURPOSE To review the response and outcomes of (177)Lu-DOTA-octreotate chemoradionuclide therapy (LuTate PRCRT) in patients with neuroendocrine tumour (NET) expressing high levels of somatostatin receptors with uncontrolled symptoms or disease progression. METHODS A total of 68 patients (39 men; 17 - 76 years of age) who had completed an induction course of at least three cycles of LuTate PRCRT between January 2006 and June 2010 were reviewed. Ten patients were treated for uncontrolled symptoms and 58 had disease progression despite conventional treatment. The majority had four induction LuTate cycles (median treatment duration 5 months and cumulative activity 31 GBq), and 63 patients had concomitant 5-FU radiosensitizing infusional chemotherapy. Factors predicting overall survival were assessed using the log-rank test and Cox proportional hazards regression. RESULTS Of those treated for uncontrolled symptoms, 70 % received benefit maintained for at least 6 months after treatment. Among patients with progressive disease 68 % showed stabilization or regression on CT, 67 % on molecular imaging and 56 % biochemically up to 12 months after treatment; 32 patients died. Overall survival rates at 2 and 5 year were 72.1 % and 52.1 %, respectively. Median overall survival was not estimable at a median follow-up of 60 months (range 5 - 86 months). Nonpancreatic primary sites, dominant liver metastases, lesion size <5 cm and the use of 5-FU chemotherapy were statistically significantly associated with objective response. A disseminated pattern and a high disease burden (whole-body retention index) were associated with an increased risk of death. Objective biochemical, molecular imaging and CT responses were all associated with longer overall survival. CONCLUSION A high proportion of patients with progressive NET or uncontrolled symptoms received therapeutic benefit from LuTate with concomitant 5-FU chemotherapy. The achievement of objective biochemical, molecular or CT responses within 12 months was associated with improved overall survival. Patients with a primary pancreatic site and larger lesions (>5 cm) appeared to have lower objective response rates and may need a more aggressive treatment approach.

Abstract
Patient participation in cancer clinical trials is low. Little is known about attitudinal barriers to participation, particularly among patients who may be offered a trial during an imminent initial oncology consult. The aims of the present study were to confirm the presence of proposed subscales of a recently developed cancer clinical trial attitudinal barriers measure, describe the most common cancer clinical trials attitudinal barriers, and evaluate socio-demographic, medical and financial factors associated with attitudinal barriers. A total of 1256 patients completed a survey assessing demographic factors, perceived financial burden, prior trial participation and attitudinal barriers to clinical trials participation. Results of a factor analysis did not confirm the presence of the proposed four attitudinal barriers subscale/factors. Rather, a single factor represented the best fit to the data. The most highly-rated barriers were fear of side-effects, worry about health insurance and efficacy concerns. Results suggested that less educated patients, patients with non-metastatic disease, patients with no previous oncology clinical trial participation, and patients reporting greater perceived financial burden from cancer care were associated with higher barriers. These patients may need extra attention in terms of decisional support. Overall, patients with fewer personal resources (education, financial issues) report more attitudinal barriers and should be targeted for additional decisional support.

Abstract
OBJECTIVE There is growing interest in the potential benefits of public involvement (PI) in health and social care research. However, there has been little examination of values underpinning PI or how these values might differ for different groups with an interest in PI in the research process. We aimed to explore areas of consensus and conflict around normative, substantive and process-related values underpinning PI. DESIGN Mixed method, three-phase, modified Delphi study, conducted as part of a larger multiphase project. SETTING The UK health and social care research community. PARTICIPANTS Stakeholders in PI in research, defined as: clinical and non-clinical academics, members of the public, research managers, commissioners and funders; identified via research networks, online searches and a literature review. RESULTS We identified high levels of consensus for many normative, substantive and process-related issues. However, there were also areas of conflict in relation to issues of bias and representativeness, and around whether the purpose of PI in health and social care research is to bring about service change or generate new knowledge. There were large differences by group in the percentages endorsing the ethical justification for PI and the argument that PI equalises power imbalances. With regard to practical implementation of PI, research support infrastructures were reported as lacking. Participants reported shortcomings in the uptake and practice of PI. Embedding PI practice and evaluation in research study designs was seen as fundamental to strengthening the evidence base. CONCLUSIONS Our findings highlight the extent to which PI is already embedded in research. However, they also highlight a need for 'best practice' standards to assist research teams to understand, implement and evaluate PI. These findings have been used in developing a Public Involvement Impact Assessment Framework (PiiAF), which offers guidance to researchers and members of the public involved in the PI process.

Abstract
The incidence of acute and chronic conditions of the tendo Achillis appear to be increasing. Causation is multifactorial but the role of inherited genetic elements and the influence of environmental factors altering gene expression are increasingly being recognised. Certain individuals' tendons carry specific variations of genetic sequence that may make them more susceptible to injury. Alterations in the structure or relative amounts of the components of tendon and fine control of activity within the extracellular matrix affect the response of the tendon to loading with failure in certain cases. This review summarises present knowledge of the influence of genetic patterns on the pathology of the tendo Achillis, with a focus on the possible biological mechanisms by which genetic factors are involved in the aetiology of tendon pathology. Finally, we assess potential future developments with both the opportunities and risks that they may carry.

Abstract
Urosepsis is a bacteraemia infection caused by an organism previously causing an infection in the urinary tract of a patient, a diagnosis which has been classically confirmed by culture of the same species of bacteria from both blood and urine samples. Given the new insights afforded by sequencing technologies into the complicated population structures of infectious agents affecting humans, we sought to investigate urosepsis by comparing the genome sequences of blood and urine isolates of Escherichia coli from five patients with urosepsis. The results confirm the classical urosepsis hypothesis in four of the five cases, but also show the complex nature of extra-intestinal E. coli infection in the fifth case, where three distinct strains caused two distinct infections. Additionally, we show there is little to no variation in the bacterial genome as it progressed from urine to blood, and also present a minimal set of virulence genes required for bacteraemia in E. coli based on gene association. These suggest that most E. coli have the genetic propensity to cause bacteraemia.

Abstract
BACKGROUND AND PURPOSE Intracerebral hemorrhage growth independently predicts disability and death. We hypothesized that noncontrast quantitative CT densitometry reflects active bleeding and improves predictive models of growth. MATERIALS AND METHODS We analyzed 81 of the 96 available baseline CT scans obtained <3 hours post-ICH from the placebo arm of the phase IIb trial of recombinant factor VIIa. Fifteen scans could not be analyzed for technical reasons, but baseline characteristics were not statistically significantly different. Hounsfield unit histograms for each ICH were generated. Analyzed qCTD parameters included the following: mean, SD, coefficient of variation, skewness (distribution asymmetry), and kurtosis ("peakedness" versus "flatness"). These densitometry parameters were examined in statistical models accounting for baseline volume and time-to-scan. RESULTS The coefficient of variation of the ICH attenuation was the most significant individual predictor of hematoma growth (adjusted R(2) = 0.107, P = .002), superior to BV (adjusted R(2) = 0.08, P = .006) or TTS (adjusted R(2) = 0.03, P = .05). The most significant combined model incorporated coefficient of variation, BV, and TTS (adjusted R(2) = 0.202, P = .009 for coefficient of variation) compared with BV and TTS alone (adjusted R(2) = 0.115, P < .05). qCTD increased the number of growth predictions within ±1 mL of actual 24-hour growth by up to 47%. CONCLUSIONS Heterogeneous ICH attenuation on hyperacute (<3 hours) CT imaging is predictive of subsequent hematoma expansion and may reflect an active bleeding process. Further studies are required to determine whether qCTD can be incorporated into standard imaging protocols for predicting ICH growth.

Abstract
BACKGROUND A clear policy trend exists towards promoting the use of direct payments (DPs), including those for families with disabled children who use short breaks. However, uptake has been slow and use of DPs has been socially patterned. Recent programmes in England have dramatically increased investment in short break provision including breaks funded through DPs. This research examines the characteristics, circumstances and experiences of families who use DPs to fund short breaks with those who use short breaks funded in other ways. METHOD The paper draws on surveys totalling 348 parents and carers in families with disabled children using short breaks. We investigate associations between the use of DPs and a range of demographic, socio-economic, well-being, service use and satisfaction indicators. Logistic regression identifies which variables are most strongly associated with use of DPs. We also draw on open-ended survey responses which highlight important aspects of families' experience of using DPs. RESULTS Characteristics significantly associated with increased use of DPs include the presence of main carers who are female, more highly educated and from White British backgrounds, younger children, lower levels of area deprivation, greater access to service and social networks and use of more hours of short breaks. Characteristics not found to be significantly associated with use of DPs include various health and well-being indicators, impairment characteristics of children and service satisfaction. A range of benefits of DPs are described along with problems accessing and using them. CONCLUSIONS Direct payments can have a number of benefits for families using short breaks, but access to them is currently problematic and socially patterned. If the uptake of DPs is to be increased and made more equitable, more attention must be paid to promoting and supporting their use in ways which meet the needs of individual families.

Abstract
A recent genetic association study has revealed that a variant (rs143383) within the 5'-untranslated region of the growth differentiation factor 5 gene (GDF5) associates with the risk of Achilles tendon pathology. The aim of this study was to determine whether this variant associates with the risk of ACL rupture. A cohort of 126 Caucasians with ACL rupture (ACL group), including 51 subjects who ruptured their ACL through a non-contact mechanism (NON sub-group), and 214 controls (CON group) were genotyped for the rs143383 variant. We report no significant GDF5 rs143383 genotype (P=0.396) or allele (P=0.810) frequency differences between the ACL (TT genotype, n=37, 29%; CT genotype, n=72, 57%; CC genotype, n=17, 14%) and CON (TT genotype, n=73, 34%; CT genotype, n=106, 50%; CC genotype, n=35, 16%) groups. There were also no significant differences between the NON sub-group and the CON group (allele; P=0.710, genotype; P=0.771). Furthermore, in gender specific analysis we found no association between rs143383 and ACL in either males (allele; P=0.988, genotype; P=0.407) or females (allele; P=0.643, genotype; P=0.885), respectively. Nor were there any gender specific associations between the NON sub-group and either genotype or allele. In conclusion, the rs143383 variant was not found to associate with the risk of ACL rupture.

Abstract
The insertion allele of the angiotensin-converting enzyme (ACE) gene has been associated with endurance performance. Since a large portion of the variance seen in circulatory ACE levels is unaccounted for by the insertion/deletion polymorphism it is likely that the ACE phenotype would serve as a more informative marker in assessing elite endurance performance. The aim of this study was to correlate plasma ACE activity with performance of a homogenous population of South African-born Caucasian male triathletes. Plasma ACE activity was determined in 145 triathletes, representing the fastest and slowest subgroups who completed either the 2000 or 2001 South African Ironman Triathlon. There was a trend for lower mean plasma ACE activity in the fastest (28.85±8.60 mU/ml) when compared to the slowest finisher subgroup (31.65±8.75 mU/ml, P=0.055). There was a significant positive correlation between plasma ACE activity and overall finishing time within the participants who completed the event in under 15 h (r=0.192, P=0.029). There was also a positive correlation with cycle (r=0.195, P=0.034) and run (r=0.184, P=0.040) stages but not the swim stage (r=0.084, P=0.353). In conclusion, this is the first study to report a relationship between plasma ACE activity and endurance performance in humans.

Abstract
OBJECTIVE Varicose veins of the lower extremities is a common clinical condition. Although surgical treatment is often successful, the recurrence rate remains high. This retrospective study evaluated the reasons for postoperative recurrence of varicose veins by analysing ultrasonography and venography findings in patients with recurrent disease. METHODS A series of consecutive cases of recurrent varicose veins of the lower limbs was reviewed. Data collected included clinical characteristics, symptoms and vascular imaging. RESULTS The study included 109 legs with recurrent varicose veins (92 patients): 101/109 legs (92.7%) showed perforating vein insufficiency and 86/109 (78.9%) showed reflux of the superficial femoral vein, of varying degrees of severity. Residual saphenous vein was recorded for 82 legs (75.2%), while 19 (17.4%) had blocked iliac veins due to post-thrombotic syndrome. CONCLUSIONS Several factors that may contribute to varicose vein recurrence have been identified. These include failure to ligate perforating veins and initial failure to perform the appropriate surgical intervention. Prevention of varicose vein recurrence after surgical correction requires a more extensive use of preoperative imaging, to tailor surgical intervention to suit individual patients.

Abstract
INTRODUCTION Knee and hip arthroplasties are recognized as being effective. However, subjects with a prosthetic joint rarely report returned sensation comparable to their native joint. HYPOTHESIS Joint perception by patients following hip joint replacement is better than following knee replacement and in both cases this perception is directly related to the clinical results measured with currently validated scores. PATIENTS AND METHODS Patient joint perception in prosthetic reconstruction was evaluated in 347 patients, 46 who underwent unicompartmental knee arthroplasty (UKA), 119 tricompartmental knee arthroplasty (TKA), 93 hip resurfacing (HR), and 89 total hip arthroplasty (THA). The subjects' joint perception, their satisfaction, and the WOMAC clinical score were recorded and compared. RESULTS Joint perception was significantly worse for knee arthroplasties (TKA and UKA) compared to hip arthroplasties (THA or HR) (P<0.001). The WOMAC score was also significantly less favorable for knee arthroplasties than for hip arthroplasties (P<0.0001). However, there was no significant difference for the clinical scores between TKA and UKA as well as between HR and THA. Joint perception was strongly correlated with the WOMAC score for all groups (R(2)=0.951). DISCUSSION No difference was found after more conservative surgeries such as HR or UKA compared to traditional arthroplasty procedures (THA or TKA). Demonstrating inferior results in comparison to the hip, knee arthroplasties deserve particular attention and can still be improved. The assessment of joint perception used in this study can be considered a valuable clinical tool that is strongly correlated to validated, but more complex to apply, clinical scores.
