Abstract
BACKGROUND Tebentafusp demonstrated a superior overall survival (OS) benefit [hazard ratio (HR) 0.51] compared to investigator's choice (82% pembrolizumab) in a randomized, phase III trial (IMCgp100-202; N = 378) in untreated metastatic uveal melanoma (mUM). The 1-year OS rates for tebentafusp and pembrolizumab were 73% and 59%, respectively. In the single-arm GEM1402 (N = 52), the 1-year OS rate for nivolumab plus ipilimumab (N+I) in mUM was 52%. Due to limitations in conducting randomized trials in mUM, we compared OS on tebentafusp or pembrolizumab (IMCgp100-202) to N+I (GEM1402) in untreated mUM using propensity scoring methods. PATIENTS AND METHODS Analyses were adjusted using propensity score-based inverse probability of treatment weighting (IPTW), balancing age, sex, baseline lactate dehydrogenase (LDH), baseline alkaline phosphatase, disease location, Eastern Cooperative Oncology Group status, and time from primary diagnosis to metastasis. OS was assessed using IPT-weighted Kaplan-Meier and Cox proportional hazard models. Sensitivity analyses using alternative missing data and weights methods were conducted. RESULTS The primary IPTW analysis included 240 of 252 patients randomized to tebentafusp from IMCgp100-202 and 45 of 52 N+I-treated patients from GEM-1402. Key baseline covariates, including LDH, were generally well balanced before weighting. The IPTW-adjusted OS favored tebentafusp, HR 0.52 [95% confidence interval (CI) 0.35-0.78]; 1-year OS was 73% for tebentafusp versus 50% for N+I. Sensitivity analyses showed consistent superior OS for tebentafusp with all IPTW HRs ≤0.61. IPTW analysis of pembrolizumab versus N+I showed no significant difference in OS (HR 0.72; 95% CI 0.50-1.06). CONCLUSIONS Tebentafusp was previously shown to provide an OS benefit compared to checkpoint inhibitors or chemotherapy in untreated mUM. Propensity score analysis demonstrated a similar OS benefit for tebentafusp compared with N+I. These data further support tebentafusp as the standard of care in previously untreated human leukocyte antigen (HLA)-A∗02:01+ adult patients with mUM.

Abstract
Interleukin (IL)-27, a member of the IL-12 family of cytokines, induces human immunodeficiency virus (HIV)-resistant monocyte-derived macrophages and T cells. This resistance is mediated via the downregulation of spectrin beta, non-erythrocytic 1 (SPTBN1), induction of autophagy, or suppression of the acetylation of Y-box binding protein-1 (YB-1); however, the role of IL-27 administration during the induction of immature monocyte-derived dendritic cells (iDC) is poorly investigated. In the current study, we investigated the function of IL-27-induced iDC (27DC) on HIV infection. 27DC inhibited HIV infection by 95 ± 3% without significant changes in the expression of CD4, CCR5, and SPTBN1 expression, autophagy induction and acetylation of YB-1 compared to iDC. An HIV proviral DNA copy number assay displayed that 27DC suppressed reverse transcriptase (RT) reaction without influencing the virus entry. A DNA microarray analysis was performed to identify the differentially expressed genes between 27DC and iDC. Compared to iDC, 51 genes were differentially expressed in 27DC, with more than 3-fold changes in four independent donors. Cross-reference analysis with the reported 2,214 HIV regulatory host genes identified nine genes as potential interests: Ankyrin repeat domain 22, Guanylate binding protein (GBP)-1, -2, -4, -5, Stabilin 1, Serpin family G member 1 (SERPING1), Interferon alpha inducible protein 6, and Interferon-induced protein with tetratricopeptide repeats 3. A knock-down study using si-RNA failed to determine a key factor associated with the anti-HIV activity due to the induction of robust amounts of off-target effects. Overexpression of each protein in cells had no impact on HIV infection. Thus, we could not define the mechanism of the anti-HIV effect in 27DC. However, our findings indicated that IL-27 differentiates monocytes into HIV-resistant DC, and the inhibitory mechanism differs from IL-27-induced HIV-resistant macrophages and T cells.

Abstract
BACKGROUND The Nile tilapia (Oreochromis niloticus) is the third most important freshwater fish for aquaculture. Its success is directly linked to continuous breeding efforts focusing on production traits such as growth rate and weight. Among those elite strains, the Genetically Improved Farmed Tilapia (GIFT) programme initiated by WorldFish is now distributed worldwide. To accelerate the development of the GIFT strain through genomic selection, a high-quality reference genome is necessary. RESULTS Using a combination of short (10X Genomics) and long read (PacBio HiFi, PacBio CLR) sequencing and a genetic map for the GIFT strain, we generated a chromosome level genome assembly for the GIFT. Using genomes of two closely related species (O. mossambicus, O. aureus), we characterised the extent of introgression between these species and O. niloticus that has occurred during the breeding process. Over 11 Mb of O. mossambicus genomic material could be identified within the GIFT genome, including genes associated with immunity but also with traits of interest such as growth rate. CONCLUSION Because of the breeding history of elite strains, current reference genomes might not be the most suitable to support further studies into the GIFT strain. We generated a chromosome level assembly of the GIFT strain, characterising its mixed origins, and the potential contributions of introgressed regions to selected traits.

Abstract
Before COVID-19, dementia singing groups and choirs flourished, providing activity, cognitive stimulation, and social support for thousands of people with dementia in the UK. Interactive music provides one of the most effective psychosocial interventions for people with dementia; it can allay agitation and promote wellbeing. Since COVID-19 has halted the delivery of in-person musical activities, it is important for the welfare of people with dementia and their carers to investigate what alternatives to live music making exist, how these alternatives are delivered and how their accessibility can be expanded. This community case study examines recent practice in online music-making in response to COVID-19 restrictions for people with dementia and their supporters, focusing on a UK context. It documents current opportunities for digital music making, and assesses the barriers and facilitators to their delivery and accessibility. Online searches of video streaming sites and social media documented what music activities were available. Expert practitioners and providers collaborated on this study and supplied input about the sessions they had been delivering, the technological challenges and solutions they had found, and the responses of the participants. Recommendations for best practice were developed and refined in consultation with these collaborators. Over 50 examples of online music activities were identified. In addition to the challenges of digital inclusion and accessibility for some older people, delivering live music online has unique challenges due to audio latency and sound quality. It is necessary to adapt the session to the technology's limitations rather than expect to overcome these challenges. The recommendations highlight the importance of accessibility, digital safety and wellbeing of participants. They also suggest ways to optimize the quality of their musical experience. The pandemic has prompted innovative approaches to deliver activities and interventions in a digital format, and people with dementia and their carers have adapted rapidly. While online music is meeting a clear current need for social connection and cognitive stimulation, it also offers some advantages which remain relevant after COVID-19 restrictions are relaxed. The recommendations of this study are intended to be useful to musicians, dementia care practitioners, and researchers during the pandemic and beyond.

Abstract
Abstract
Background
Many Heart Failure with preserved Ejection Fraction (HFpEF) patients have metabolic syndrome and develop Exercise Induced Pulmonary Hypertension (EIPH). The pathogenesis of EIPH in HFpEF remains unclear as there is no rodent model. As the SGLT2 inhibitor Empagliflozin improves clinical outcome in patients with type 2 diabetes and cardiovascular risk, we tested its effect on EIPH in a novel rat model of HFpEF.
Methods
Obese ZSF1 (HFpEF model) with leptin receptor mutation have metabolic syndrome and received the VEGF-inhibitor SU5416 to stimulate PH (Obese + Sugen). Half also received Empagliflozin (0.2 mg/kg/day) in drinking water from 8 to 22 weeks old. Lean ZSF1 lacking the mutation served as controls. During treadmill exercise, right/left ventricle (RV/LV) hemodynamics were evaluated via catheters. Pulmonary artery vascular smooth muscle cells (PAVSMC) prepared from normal or diabetic patients were cultured in standard media, or with Palmitate acid, Glucose and Insulin (PGI) to induce metabolic stress. Flow cytometry was used to evaluate reactive oxygen species (ROS) in mitochondria (Mitosox) or cytoplasm (CellROX).
Results
Relative to Lean, Obese + Sugen had increased body weight and HgA1C (Fig. 1A). Relative to Lean and at rest, Obese + Sugen showed mildly elevated RVSP and LVEDP. After exercise, LVSP and LVEDP rose similarly in Lean and Obese + Sugen. However, after exercise, Obese + Sugen showed a markedly greater increase in RVSP and exercise intolerance consistent with EIPH (Fig. 1B). In MR imaging of PA, Lean showed dobutamine (5 μg/kg/min)-induced PA dilation, which was not seen in Obese + Sugen (Fig. 1C). Protein levels of sGCβ1 (key regulator of PA relaxation) and its transcription factor (NFYA) both were decreased in PA from Obese + Sugen relative to Lean (Fig. 1D). Obese + Sugen + SGLT2 inhibitor treated rats showed marked improvements metabolic syndrome (body weight, HgA1c), exercise induced increase in RVSP, PA response to dobutamine, and increased NFYA and sGCβ1 expression (Fig. 1A–D). We observed greater ROS-induced DNA damage (8-OHdG staining) (Fig. 1E) and mitochondrial complex I, III, and IV activity in Obese + Sugen PA that was normalized in Obese + Sugen + SGLT2 inhibitor (Fig. 1F), suggesting a role of ROS in EIPH. Control human PAVSMC treated with PGI media showed elevated cytoplasmic and mitochondrial ROS, associated with increased mitochondrial complex I, III, IV and V activity (Fig. 1F, G). PGI media also accelerated the degradation of NFYA RNA and protein level in a manner mimicked by H2O2, and prevented by catalase/SOD (Fig. 1H, I), suggesting PGI-induced ROS enhanced NFYA degradation. Diabetic human PAVSMCs cultured in normal media resembled PGI-treated normal cells with respect to sGCb1 and NFYA expression, and in response to catalase/SOD (Fig. 1H, I).
Conclusions
In this PH-HFpEF model, metabolic syndrome contributes to PA dysfunction and EIPH through mitochondrial dysfunction and enhanced ROS, which were improved by Empagliflozin treatment.

Abstract
In order to predict outcome after a stroke and set realistic targets for rehabilitation, it is essential to have reliable information on the patient's premorbid functional status. We assessed the availability of information on premorbid continence, mobility and mental status by examining the medical and nursing notes, one week after admission to a teaching hospital, of 164 stroke patients. Simple rating scales were used and results compared to information obtained from patients' relatives. Useful information on previous mobility was obtained from the notes in 58% of cases, on continence in 47%, and mental state in 44%. Although agreement between medical and nursing notes was reasonable (possibly due to sharing of information), agreement with the same information obtained from relatives was very poor. Information on the premorbid functional status of stroke patients is often not available in hospital notes, and when recorded is often inaccurate. Such data should be routinely obtained using standardized measures.

Abstract
Despite evidence that intensive rehabilitation speeds recovery from acute illness, several studies on British rehabilitation units have shown that the time spent by patients in therapeutic activities is low and that levels of 'engagement' are poor. We carried out an observational study of patient activity on four rehabilitation wards for the elderly (51 patients observed at half-hourly intervals between 8 a.m. and 5 p.m. on five successive days). Patients were found to be engaged in therapeutically useful activities at only 17% of the observation points. When time spent in the therapy departments (where activities were not monitored) was excluded the proportion of useful activities fell to 11%. Similar patterns of activity were seen in all patient subgroups. An intervention scheme was therefore devised, whereby an hourly activities programme tailored to the needs of each patient was worked out by therapists and ward staff, to be supervised by nurses. One nurse also organized regular group activities. The intervention programme, which required no extra resources, was instituted on two of the four wards. A repeat survey conducted two months later showed a 55% increase in the proportion of time spent in useful activities on the two intervention wards but no change on the other two wards.

Abstract
Objective: To develop and evaluate a qualitative and quantitative instrument for selecting the ideal mobility aid for those with mobility disorders. Setting: A district general hospital-based geriatric unit. Subjects: Elderly inpatients and outpatients with mobility disorders. Interventions: Structured assessments with different mobility aids to select the most suitable. Outcome measures: Safety, stance, stability, step/stride pattern and speed were considered. Results: The 'S' test successfully selected an aid for all 49 subjects. For most this aid offered marked improvement in qualitative and quantitative aspects of gait when compared with the subject's usual aid. Conclusions: The 'S' test is an effective tool for selecting mobility aids within an institutional setting.

Abstract
BACKGROUND Recent studies have described the bifidobacterial composition of neonates at a species level; however, with advancing technologies we can gain insight into the diversity of the bifidobacterial microbiota residing within the infant gut. OBJECTIVE To compare species and strain diversity of culturable bifidobacterial populations in faecal samples obtained from healthy term infants on three different feeding regimes. STUDY DESIGN In total, 51 healthy term infants were recruited for this study and divided equally into three different groups (n=17) based on their feeding regime during the first 4 weeks of life. Culturable bifidobacterial populations were analysed at week 1, week 4 and 6 months of age. Isolates were characterised to species level by 16s rRNA-internally transcribed spacer (ITS) gene sequence analysis and to strain level by pulsed field gel electrophoresis (PFGE). RESULTS In total,173 bifidobacterial strains were detected across all three groups from 2295 isolates, 42% (72 of 173) of which were detected in the prebiotic-fed group, followed by 30% (52 of 173) and 28% (49 of 173) in the breastfed and non-prebiotic-fed groups, respectively. Surprisingly, only two of the 51 infants harboured an identical bifidobacterial strain which was not present in the other 49 infants. Prebiotic supplementation in the early neonatal period increased the prevalence of Bifidobacterium longum in infants, in addition to promoting strain diversity. B. longum was the dominant species recovered from all three groups during the first 6 months of life, followed by Bifidobacterium breve and Bifidobacterium bifidum. CONCLUSIONS This study reveals a hitherto unknown level of diversity at the strain level among bifidobacteria isolated from different infants and the influence prebiotic formula feeding has on the bifidobacterial population.

Abstract
We conducted an exploratory, qualitative study investigating the factors influencing the use of genetic counseling and prenatal genetic testing for two groups: pregnant women 35 years of age and over (AMA) at the time of delivery and pregnant women with an abnormal maternal serum triple screen (MSAFP3). The convenience sample consisted of 25 semistructured interviews of women/couples and 50 observations of genetic counseling sessions. Worry turned out to be the most important variable influencing decision making about prenatal genetic testing and was greater in the MSAFP3 group than in the AMA group. The women in the AMA group appeared to assign the risk of having a child with Down syndrome to their age category rather than to themselves individually, whereas, the risk perception for women with an abnormal MSAFP3 appeared to have shifted from a general population risk for pregnant women to an individual, personal risk. There was a general lack of understanding and also more misinformation about the MSAFP3 screen compared to amniocentesis. Women in both groups were torn between fear of an invasive test and worry about the health of their fetus for the rest of their pregnancy if they did not undergo amniocentesis.

Abstract
We conducted an exploratory, qualitative pilot study investigating the use of genetic counseling and prenatal genetic technologies between women and their male partners for two referral groups: pregnant women 35 years of age and over (AMA) at the time of delivery and pregnant women with an abnormal maternal serum triple screen (MSAFP3). The convenience sample consisted of 25 semistructured interviews and 50 observations of genetic counseling sessions. Male partners' styles of decision making and the way they viewed prenatal diagnosis decision making were examined. We defined three decision-making styles based on our interpretation of the data: (1) domain, (2) joint-delegated, and (3) saliency. The male partners also seemed to view prenatal diagnosis as either an information decision or an action decision and appeared to take a more active role in decision making when the decision was viewed as an action decision.

Abstract
Background: Despite the high prevalence of upper limb sensorimotor impairments among stroke victims, very few evidence-based reviews exist about the functional benefit of sensory-focussed therapeutic interventions upon the hemiplegic upper limb following stroke. This systematic-review aims to address this concern to determine the efficacy of sensory-focussed therapeutic interventions upon functional outcomes in the hemiplegic upper limb following stroke. Methods: Studies included within the systematic review were sourced from the following databases: Medline; SPORTDiscus; AMED; CINAHL; and PEDro, via EBSCO Host. The keywords used to obtain the pertinent literature were: ‘stroke’, ‘therapy’, ‘rehabilitation’, ‘function’, ‘upper limb’ and ‘sensory’. The reference list of each retrieved paper was hand searched to identify any additional relevant literature. Two independent researchers applied the specific inclusion/exclusion criteria to each paper to eliminate any irrelevant studies. The methodological quality of each of the selected papers was assessed using a modified version of the Downs and Black checklist. This gave a final total of 11 studies to be included within the systematic review. A data extraction form was devised and all relevant data was extrapolated from each study by two independent researchers. For each study, primary outcome measures were compared between the experimental group and the control group, pre- and post-treatment using the mean and standard deviation values. Statistical significance of these values was also assessed and compared using the respective P values. Results: Statistically significant results from all the included studies suggest that functional motor abilities of the hemiplegic upper limb following stroke can be improved by the application of the following sensory-focussed interventions: mirror therapy; thermal therapy; transcutaneous electrical stimulation; intermittent pneumatic compression; and proprioceptive and exteroceptive stimulation therapy. Due to significant differences in methodology and outcome measures, it was difficult to draw a comparison between the efficacies of specific sensory interventional subtypes evaluated within this review. Conclusions: This systematic review provides evidence to support the use of several sensory-focused therapeutic interventions for improving motor recovery in the hemiplegic upper-limb following stroke. Implications: This review indicates that sensory-focused therapeutic interventions should be employed in clinical practice as an evidence-based means to improve the functional abilities of patients with hemiplegic upper limbs post stroke.

Abstract
For patients with chronic renal and liver diseases, simultaneous liver and kidney transplantation (SLKT) is the best therapeutic option. The role of a pretransplant donor-specific antibody (DSA) in SLKT is unclear. We report the results of a retrospective review from 7/08 to 10/09 of SLKT at our institution. Monitoring of DSA was performed using single antigen bead assay. Between 7/08 and 10/09, there were six SLKT who had preformed DSA and positive XM (four class I and II DSA, one class I DSA only, one class II only). One-year patient and renal graft survival was 83%. Death-censored liver allograft survival was 100%. Acute humoral rejection (AHR) of the kidney occurred in 66% (three with both class I and II DSA and one with only class II DSA) of patients. In those with AHR, class I antibodies were rapidly cleared (p < 0.01) while class II antibodies persisted (p = 0.25). All patients who had humoral rejection of their kidney had preformed anticlass II antibodies. Liver allografts may not be fully protective of the renal allograft, especially with pre-existing MHC class II DSA. Long-term and careful follow-up will be critical to determine the impact of DSA on both allografts.

Abstract
384 Background: The impact of neoadjuvant or preoperative therapy in the setting of advanced renal cell carcinoma on recurrence-free or survival outcomes is not known. Methods: 28 patients with renal cell carcinoma were treated with preoperative sorafenib in a prospective pilot study (LCCC 0603). Patient files were reviewed a median of 885 days (2.42 years) following nephrectomy. Records were evaluated for 13 patients with nonmetastatic disease for development of recurrence, and for 15 patients with stage IV disease for survival. Results: For the nonmetastatic patients, only 2 patients had developed recurrent disease, one underwent metastectomy and remains in surveillance and the other is on second line systemic targeted therapy. A median recurrence-free survival has not been met after a median 2.5 years. For stage IV disease patients at a median follow up of 2.3 years, a median survival has also not been reached. Four patients are deceased, one patient is lost to follow up, and 10 remain alive. Treatments for metastatic disease included continued sorafenib, high dose interleukin-2, sunitinib, pazopanib, temsirolimus, and everolimus. Some stage IV patients have also enjoyed prolonged treatment-free intervals ranging from six months to over two years, with biopsy confirmed, but indolent disease. Conclusions: Although these data are descriptive, these observations are suggestive that preoperative therapy with sorafenib is unlikely to accelerate the growth of grossly metastatic or micrometastatic disease. Further studies are needed to determine whether preoperative therapy is valuable in improving recurrence-free or overall survival endpoints. [Table: see text]

Abstract
8006^ Background: IPASS demonstrated overall superiority of first-line G vs C/P for progression-free survival (PFS) in never/light ex-smokers with stage IIIB/IV adenocarcinoma NSCLC in Asia. PFS favored CP initially and then G. Outcome was correlated with biomarkers (preplanned exploratory objective). Methods: 683 patients provided tissue samples. Analyses included primary endpoint PFS (Cox proportional hazards) and secondary endpoint objective response rate (ORR; logistic regression) by biomarker status. Results: EGFR mutation (M) status was evaluable in 437 pts by Amplification Refractory Mutation System (ARMS; 60% M+). M+ pts had significantly longer PFS and higher ORR and M- pts significantly shorter PFS and lower ORR with G than C/P. In M unknown pts PFS and ORR were similar to overall population. Post hoc analysis of overall survival favored G in M+ pts (31% maturity; HR 0.78; 95% CI 0.50–1.20) and C/P in M- pts (53% maturity; HR 1.38; 95% CI 0.92–2.90); differences were not statistically significant and follow-up is ongoing. EGFR gene-copy number was evaluable in 406 pts by fluorescence in situ hybridization (FISH; 61% FISH +). Similar PFS and ORR results to analyses by M status were observed, driven by the overlap in EGFR FISH and M status. EGFR protein expression (PE) was evaluable in 365 pts by immunohistochemistry (73% PE+). PFS outcomes did not differ statistically between PE+ and PE-. ORR favored G in both PE+ and - pts. Conclusions: EGFR M status was a strong predictive biomarker for the efficacy of G vs C/P in this clinically selected first-line setting.

Abstract
BACKGROUND Urinary incontinence can affect 40-60% of people admitted to hospital after a stroke, with 25% still having problems on hospital discharge and 15% remaining incontinent at one year. OBJECTIVES To determine the optimal methods for treatment of urinary incontinence after stroke in adults. SEARCH STRATEGY We searched the Cochrane Incontinence and Stroke Groups specialised registers (searched 15 March 2007 and 5 March 2007 respectively), CINAHL (January 1982 to January 2007), national and international trial databases for unpublished data, and the reference lists of relevant articles. SELECTION CRITERIA Randomised or quasi-randomised controlled trials evaluating the effects of interventions designed to promote continence in people after stroke. DATA COLLECTION AND ANALYSIS Data extraction and quality assessment were undertaken by two reviewers working independently. Disagreements were resolved by a third reviewer. MAIN RESULTS Twelve trials with a total of 724 participants were included in the review. Participants were from a mixture of settings, age groups and phases of stroke recovery. BEHAVIOURAL INTERVENTIONS: Three trials assessed behavioural interventions, such as timed voiding and pelvic floor muscle training. All had small sample sizes and confidence intervals were wide. SPECIALISED PROFESSIONAL INPUT INTERVENTIONS: Two trials assessed variants of professional input interventions. Results tended to favour the intervention groups: in a small trial in early rehabilitation, fewer people had incontinence at discharge from hospital after structured assessment and management than in a control group (1/21 vs. 10/13; RR 0.06, 95% CI 0.01 to 0.43); in the second trial, assessment and management by Continence Nurse Advisors was associated with fewer participants having urinary symptoms (48/89 vs. 38/54; RR 0.77, 95% CI 0.59 to 0.99) and statistically significantly more being satisfied with care. COMPLEMENTARY THERAPY INTERVENTIONS: Three small trials all reported fewer participants with incontinence after acupuncture therapy (overall RR 0.44; 95% 0.23 to 0.86), but there were particular concerns about study quality. PHARMACOTHERAPY AND HORMONAL INTERVENTIONS: There were three small trials that included groups allocated meclofenoxate, oxybutinin or oestrogen. There were no apparent differences other than in the trial of meclofenoxate where fewer participants had urinary symptoms in the active group than in the control group (9/40 vs. 27/40; RR 0.33, 95% CI 0.18 to 0.62). AUTHORS' CONCLUSIONS Data from the available trials are insufficient to guide continence care of adults after stroke. However, there was suggestive evidence that professional input through structured assessment and management of care and specialist continence nursing may reduce urinary incontinence and related symptoms after stroke. Better quality evidence is required of the range of interventions that have been suggested for continence care after stroke.

Abstract
7576 Background: Tumor tissues obtained from the ISEL phase III trial assessing the efficacy of gefitinib vs placebo in chemotherapy-pretreated NSCLC were used to evaluate two Abs (DAKO and Zymed) and assess whether different cut points of EGFR protein expression improved prediction of response and survival benefit from gefitinib. Methods: EGFR protein expression in tumor samples was assessed by immunohistochemistry using DAKO EGFR pharmDx kit (scoring percent of tumor cells with positive staining, predefined cut point of =10%) and Zymed monoclonal Ab clone 31G7 (scoring proportion of positive cells times staining intensity [scale 0–400], predefined cut point of =200). Results: Clinical characteristics of the patients (pts) assessed with DAKO (n=379) and Zymed (n=357) Abs reflected the overall study population (N=1692) with the exception of fewer never-smokers and Asians. Of the pts evaluated with DAKO/Zymed Abs, females represented 32%/31%; never-smokers, 13%/14%; Asians, 6%/4%; adenocarcinomas, 44%/42%; and 88%/88% of pts were refractory to most recent chemotherapy. With the above criteria, 70% of tumor samples were scored as positive using DAKO Ab and 68% using the Zymed Ab (agreement between assessments 76%). The objective response rates in gefitinib treated EGFR-positive pts defined with various cut points with DAKO Ab (=1% to =90%) varied between 8% and 12%, and with Zymed Ab (score =50 to =350), between 10% and 13%. Lower cut points with the DAKO Ab provided the best discrimination between EGFR positive and EGFR negative patients in terms of survival hazard ratios (HRs) comparing gefitinib to placebo, with a significant treatment/cut point interaction for the 10% cut point (p=0.049). A similar trend was noted for Zymed Ab, although the discrimination between HRs was less apparent and not significant for any cut point analyzed. Conclusion: Assessment with DAKO PharmDx kit, according to percentage of positive staining, may provide more accurate prediction of survival benefit for gefitinib-treated pts than assessment with Zymed Ab and staining index. Use of higher cut points to define positivity does not improve discrimination of the test. No significant financial relationships to disclose.

Abstract
Theoretical frameworks provide generalised accounts of illness action although empirical studies of the process are still in short supply. This study of upper limb pain provided a case study of illness action; as it is a common condition, there is uncertainty about its treatment and management, orthodox and non-orthodox care are seen as legitimate sources of help and it is linked with a range of causes. Face-to-face informal interviews were carried out with 47 informants with upper limb pain and their practitioners (n= 19). The data were analysed in two different ways. The general stages of the illness action process were identified through a descriptive analysis of the upper limb pain sufferers' accounts and the policies and practices reported by their practitioners. Then, case studies were constructed to depict individual pathways through healthcare and consequences for sufferers. The illness action process was characterised by the normalisation and accommodation of pain informed by a discourse that predominantly invoked ageing and the wear and tear of the body. Practitioners also preferred to adopt a biomechanical approach and were reluctant to attribute psychosocial labels. The case studies illustrated the divergent, negotiated and opportunistic nature of the process and showed that the use of both orthodox and non-orthodox care formed only part of strategies used to manage upper limb pain. Sufferers evaluated the care they received in terms of pain alleviation, and were resigned to searching for the best way of living with their pain.

Abstract
Two subsets of sheep afferent lymph dendritic cells (DC) are defined by the differential expression of CD172a and CD45RA. The majority (~70%) of CD172a(+) subset is CD45RA/CD11c(+)/CD207(+)/TLR4(+). The CD172a(-) DC are CD45RA(+)/CD207(-) and express low levels of CD11c and CD86. Real-time RT-PCR showed that CD172(+) DC produce IL-1beta and IL-10 and high levels of IL-18 but almost no IL-12p40; CD172a(-) DC express IL-12p40 but no IL-10 and low levels of IL-1beta and IL-18. Gene gun-delivered granulocyte-macrophage colony-stimulating factor (pGM-CSF) caused an early rise in the output of CD172a(+) DC, changes to DC phenotype and significant increases in the levels of expression cytokine transcripts. However, pGM-CSF did not affect any qualitative changes to cytokine expression, CD172a(+) DC remained IL-10(+)/IL-12p40(-) and the CD172(-) DC remained IL-10(-)/IL-12p40(+).

Abstract
BACKGROUND Beliefs and mental well-being could influence decisions to consult about upper limb pain and satisfaction with care. OBJECTIVES To describe beliefs about upper limb pain in the community and explore associations of beliefs and mental health with consulting and dissatisfaction. METHODS Questionnaires were mailed to 4998 randomly chosen working-aged patients from general practices in Avon. We asked about upper limb pain, consulting, beliefs about symptoms, dissatisfaction with care, somatizing tendency (using elements of the Brief Symptom Inventory) and mental well-being (using the Short-Form 36). Associations were explored by logistic regression. RESULTS Among 2632 responders, 1271 reported arm pain during the past 12 months, including 389 consulters. A third or more of responders felt that arm pain sufferers should avoid physical activity, that problems would persist beyond 3 months, that a doctor should be seen straightaway and that neglect could lead to permanent harm. Consulters were significantly more likely to agree with these statements than other upper limb pain sufferers. The proportion of consultations attributable to such beliefs was substantial. Dissatisfaction with care was commoner in those with poor mental health: the OR for being dissatisfied (worst versus best third of the distribution) was 3.2 (95% CI 1.2-8.5) for somatizing tendency and 2.4 (95% CI 1.3-4.7) for SF-36 score. Both factors were associated with dissatisfaction about doctors' sympathy, communication and care in examining. CONCLUSIONS Negative beliefs about upper limb pain are common and associated with consulting. Somatizers and those in poorer mental health tend, subsequently, to feel dissatisfied with care.

Abstract
4538 Background: Sorafenib is a VEGFR/PDGFR-β/Raf inhibitor that improves PFS in metastatic RCC with a RR of 2%. IFN-α improves OS in RCC with a RR of ≈10%. Methods: Based on the activity of sorafenib and IFN-α in RCC, a phase II combination trial was undertaken. Pts with RCC of any histology were eligible if they had received ≤1 prior treatment (excluding IFN-α). Treatment consisted of 8-wk cycles of sorafenib 400 mg po bid + IFN-α2b 10 MU sc tiw. Cycles were repeated until disease progression with 2-wk breaks between cycles permitted. This single-stage trial has a planned n = 40; primary objectives are RR and tolerability. Results: From November 2004-December 2005, 31 pts were enrolled. Pt characteristics included: median age 47, M/F: 23/8, PS 0/1: 25/6, clear cell/papillary: 24/3, no prior Rx/prior high-dose IL-2: 17/12, prior Nx: 26. Toxicities (n = 27) were mostly grade 1/2: fatigue (78%), anorexia (74%), rash (70%; 11% grade 3), diarrhea (67%), weight loss (63%), hypophosphatemia (59%; 33% grade 3), nausea (56%), neutropenia (48%; 19% grade 3), alopecia (44%), and oral mucositis (26%). Dose reductions of both agents for toxicity occurred in 58% of pts. The most common reasons for dose reduction were grade 3 rash or neutropenia and grade 2 fatigue or anorexia. Among 24 pts evaluable for response, the RR by RECIST criteria was 42% (38% PR, 4% CR). An additional 46% had stable disease for at least 1 cycle, including 8% with ≥20% regression. Responses were seen in lungs, pleura, kidney, liver, pancreas, and nodes. Three of the 10 responses occurred in patients who had failed prior high-dose IL-2. Conclusions: Sorafenib + IFN-α2b is a well-tolerated outpatient regimen with substantial antitumor activity in both untreated and IL-2-resistant metastatic RCC. Further investigation of this regimen in RCC is warranted. [Table: see text]

Abstract
BACKGROUND There is an increasing body of evidence to support the benefits of reducing low-density lipoprotein cholesterol (LDL-C) levels and this has been reflected in a lowering of LDL-C goals recommended by international guidelines. Therefore, there is a growing need for effective lipid-modifying therapies to optimise the achievement of these more stringent LDL-C goals. OBJECTIVE A meta-analysis of data pooled from five studies participating in the DISCOVERY (DIrect Statin COmparison of LDL-C Values: an Evaluation of Rosuvastatin therapY) Programme was performed to compare the effect of rosuvastatin treatment with other statins in real-life clinical practice. RESULTS These studies included 6743 patients with hypercholesterolaemia from different ethnicities, countries and cultural environments. The meta-analysis showed that significantly more patients receiving rosuvastatin 10 mg achieved the 2003 European LDL-C goals compared with those who received atorvastatin 10 mg or simvastatin 20 mg (p < 0.001 for both comparisons). A significantly greater proportion of patients receiving rosuvastatin 10 mg also achieved the 2003 European total cholesterol goal compared with those on atorvastatin 10 mg (p < 0.001). CONCLUSIONS The meta-analysis showed that rosuvastatin was more effective than comparator statins at lowering LDL-C levels and enabling patients to achieve lipid goals at recommended start doses. In addition, all statins studied were well tolerated and confirmed that rosuvastatin had a similar safety profile to other statins.

Abstract
BACKGROUND The uncertainty about the status of upper limb disorders (ULDs), particularly the non-specific conditions, is believed to have consequences for clinical management and patient care. OBJECTIVE This paper presents evidence about how sufferers with ULDs respond to their pain, how their pain is managed, when and who they go to for formal help and how sufferers evaluate the care they receive. METHODS The data analysis is derived from face-to-face, informal interviews with sufferers with a broad spectrum of upper limb disorders (n = 47). These informants were selected according to strict criteria from a 'screening' postal survey of the working population (25-64 years) in south-west England (n = 2781). RESULTS Ideas about causation were crucial to understanding patterns of illness action and help seeking behaviour. The common strategy was to wait and see what happens as the pain was believed to be a natural part of the ageing process. Explanations invoking psychosocial and work related causes were less common and tended to be used when biomechanical explanations were no longer appropriate. Self-management was the preferred strategy but orthodox practitioners were usually the first choice for formal care. Complementary and alternative medicines (CAM) were popular but were used to complement orthodox care. Practitioners were evaluated mainly in terms of their ability to alleviate pain. CONCLUSION There is a need for orthodox and non-orthodox care to be closely integrated in primary care and GPs should not depend on orthodox medications alone when caring for patients with upper limb pain.

Abstract
PURPOSE The purpose of this assessment was to evaluate reporting of observational studies in the pediatric dental literature. METHODS This assessment included the following steps: (1) developing a model for reporting information in clinical dentistry studies; (2) identifying treatment comparisons in pediatric dentistry that were evaluated by at least 5 observational studies; (3) abstracting from these studies any data indicated by applying the reporting model; and (4) comparing available data elements to the desired data elements in the reporting model. RESULTS The reporting model included data elements related to: (1) patients; (2) providers; (3) treatment details; and (4) study design. Two treatment comparisons in pediatric dentistry were identified with 5 or more observational studies: (1) stainless steel crowns vs amalgams (10 studies); and (2) composite restorations vs amalgam (5 studies). Results from studies comparing the same treatments varied substantially. Data elements from the reporting model that could have explained some of the variation were often reported inadequately or not at all. CONCLUSIONS Reporting of observational studies in the pediatric dental literature may be inadequate for an informed interpretation of the results. Models similar to that used in this study could be used for developing standards for the conduct and reporting of observational studies in pediatric dentistry.

Abstract
BACKGROUND AND AIMS There is considerable uncertainty over the diagnosis, treatment and management of upper limb pain, which has implications for patient care. Research into patient experiences and evaluation of health-care has been neglected and the study presented here aims to fill this gap. METHODS A two-staged, mixed methodology was adopted. Phase 1 involved a postal survey of a random sample (n = 2781) of the working age population (25-64) of an area in south-west England. Phase 2 consisted of follow-up, informal face-to-face interviews with a purposive sample of 47 informants identified, according to pre-defined criteria, from the survey sample. RESULTS Our data showed that concerns about the effectiveness of treatments for alleviating pain were fundamental to users' evaluations of both orthodox and non-orthodox health-care. This took priority over the need for a diagnosis and other information. There was a general recognition that the treatments available were, at least, only partially effective and the pragmatic approach led some to eventually withdraw from both orthodox care and complementary and alternative medicines (CAM). CONCLUSION Patients' priorities for health-care, in this context, were perceived to involve the provision of treatments which alleviated pain and were safe and painless. Orthodox and non-orthodox care needed to be more closely integrated into primary care services.

Abstract
BACKGROUND Urinary incontinence can affect 40-60% of people admitted to hospital after a stroke, with 25% still having problems on hospital discharge and around 15% remaining incontinent at one year. OBJECTIVES To determine the optimal methods for prevention and treatment of urinary incontinence after stroke in adults. SEARCH STRATEGY We searched the Cochrane Incontinence and Stroke Groups specialised registers (searched 15 December 2004 and 26 October 2004, respectively), CINAHL (January 1982 to November 2004), national and international trial databases for unpublished data, and the reference lists of relevant articles. SELECTION CRITERIA Randomised or quasi-randomised controlled trials evaluating the effects of interventions designed to promote continence in people after stroke. DATA COLLECTION AND ANALYSIS Data extraction and quality assessment were undertaken by two reviewers working independently. Disagreements were resolved by a third reviewer. MAIN RESULTS Seven trials with a total of 399 participants were included in the review. Participants were from a mixture of settings, age groups and phases of stroke recovery. No two trials addressed the same comparison. Four trials tested an intervention against usual care, including acupuncture, timed voiding, and two types of specialist professional intervention. One cross-over trial tested an intervention (oestrogen) against placebo. One trial tested a specific intervention (oxybutynin) against another intervention (timed voiding), and one trial tested a combined intervention (sensory-motor biofeedback plus timed voiding) against a single component intervention (timed voiding alone). Reported data were insufficient to evaluate acupuncture or timed voiding versus usual care, oxybutynin versus timed voiding, or sensory motor biofeedback plus timed voiding versus usual care. Evidence from a single small trial suggested that structured assessment and management of care in early rehabilitation may reduce the number of people with incontinence at hospital discharge (1/21 versus 10/13; RR 0.06, 95% CI 0.01 to 0.43), and have other benefits. Evidence from another trial suggested that assessment and management of care by Continence Nurse Practitioners in a community setting may reduce the number of urinary symptoms (48/89 versus 38/54; RR 0.77, 95% CI 0.59 to 0.99), and increase satisfaction with care. AUTHORS' CONCLUSIONS There was suggestive evidence that specialist professional input through structured assessment and management of care and specialist continence nursing may reduce urinary incontinence after stroke. Data from trials of other physical, behavioural, complementary and anticholinergic drug interventions are insufficient to guide continence care of adults after stroke.

Abstract
AIM The metabolic syndrome (MS) increases the risk of coronary heart disease, yet few data are available on the effects of statin treatment in improving lipid measures in patients with the syndrome. This analysis compares the effects of statin therapy on plasma low-density lipoprotein cholesterol (LDL-C) goal achievement and lipid levels in hypercholesterolaemic patients with or without the MS. METHODS The Measuring Effective Reductions in Cholesterol Using Rosuvastatin TherapY I (MERCURY I) trial compared rosuvastatin 10 mg with atorvastatin 10 mg and 20 mg, simvastatin 20 mg and pravastatin 40 mg over 8 weeks in patients with coronary or other atherosclerotic diseases or diabetes who had fasting levels of LDL-C of >or=2.99 mmol/l and triglycerides of <4.52 mmol/l. Modified National Cholesterol Education Program Adult Treatment Panel III (ATP III) criteria for the MS were met by 1342 (43%) of 3140 patients. RESULTS LDL-C goal achievement rates and reductions in LDL-C, total cholesterol and non-high-density lipoprotein cholesterol (HDL-C) were similar in patients with and without the MS within statin treatment groups; triglycerides were reduced more and HDL-C tended to be increased more in patients with the MS, as expected. Treatment with rosuvastatin 10 mg was more effective in allowing patients with and without the MS to reach European and ATP III LDL-C goals, compared to atorvastatin 10 mg, simvastatin 20 mg and pravastatin 40 mg (p < 0.0001 for all comparisons); consistently produced greater reductions in LDL-C, total cholesterol and non-HDL-C, compared to these treatments; and produced similar or greater reductions in triglycerides and increases in HDL-C, compared to the other treatments. CONCLUSIONS Statin therapy is effective in allowing LDL-C goal achievement and improving the lipid profile in hypercholesterolaemic high-risk patients with the MS. Rosuvastatin 10 mg presents significant advantages in goal achievement and lipid lowering over other statins at commonly used doses in patients both with and without the MS.

Abstract
The prevalence of coronary heart disease (CHD) has been increasing in the past few decades in Japan, as it has in industrialised countries worldwide. CHD risk can be substantially reduced by lowering low-density lipoprotein cholesterol (LDL-C) in patients with dyslipidaemia. Statins are highly effective for this indication, but many patients treated with these drugs still do not meet their treatment goals, often because clinicians fail to titrate these patients to a higher, potentially more effective, dose. Thus, there is a need for more effective agents that can help patients reach their goals at starting doses. This paper reviews key clinical results for a new agent, rosuvastatin. The data show that rosuvastatin 5 mg is highly effective in lowering LDL-C to recommended levels for most patients (mean reductions ranging from 42 to 52%). In addition, rosuvastatin 5 mg effectively lowers triglycerides (-16%), total cholesterol (-30%), non-high-density lipoprotein cholesterol (non-HDL-C; -38%) and apolipoprotein (apo) B levels (-33%) and increases HDL-C (+8.2-13%) in a wide range of patients with hypercholesterolaemia, including the elderly, obese patients, postmenopausal women and patients with hypertension, CHD, diabetes and metabolic syndrome. The 5-mg dose of rosuvastatin dose also produces greater reductions in LDL-C and larger increases in HDL-C than recommended initial doses of atorvastatin, simvastatin or pravastatin (for LDL-C reductions, p <0.001 vs. atorvastatin 10 mg, simvastatin 20 mg and pravastatin 20 mg; for HDL-C elevations, p <0.01 vs. atorvastatin 10 mg). These results demonstrate that rosuvastatin 5 mg produces favourable effects on the lipid profile and helps more patients achieve LDL-C goals than comparator statins.
