Abstract
BACKGROUND Children with Developmental Co-ordination Disorder (DCD) experience poor motor and psychosocial outcomes. Interventions are often limited within the healthcare system, and little is known about how technology might be used within schools or homes to promote the motor skills and/or psychosocial development of these children. This study aimed to evaluate whether short, regular school-based sessions of movement experience using a commercially available home video game console (Nintendo's Wii Fit) would lead to benefits in both motor and psychosocial domains in children with DCD. METHODS A randomized crossover controlled trial of children with movement difficulties/DCD was conducted. Children were randomly assigned to an intervention (n = 10) or comparison (n = 8) group. The intervention group spent 10 min thrice weekly for 1 month using Wii Fit during the lunch break, while the comparison group took part in their regular Jump Ahead programme. Pre- and post-intervention assessments considered motor proficiency, self-perceived ability and satisfaction and parental assessment of emotional and behavioural problems. RESULTS Significant gains were seen in motor proficiency, the child's perception of his/her motor ability and reported emotional well-being for many, but not all children. CONCLUSIONS This study provides preliminary evidence to support the use of the Wii Fit within therapeutic programmes for children with movement difficulties. This simple, popular intervention represents a plausible method to support children's motor and psychosocial development. It is not possible from our data to say which children are most likely to benefit from such a programme and particularly what the dose and duration should be. Further research is required to inform across these and other questions regarding the implementation of virtual reality technologies in therapeutic services for children with movement difficulties.

Abstract
While largely preventable, fire and hot water-related injuries are common in the United States. Measures recommended to reduce these injuries are smoke alarms (SAs) and lowered hot water temperatures. This study aims to: (i) describe the prevalence of working SAs and safe water temperatures among low-income, urban communities and (ii) explore the relationship between these behaviors and individuals' knowledge and beliefs about them. In this cross-sectional study, the Health Belief Model was used as a guide for understanding the safety behaviors. A total of 603 households had their SAs and hot tap water temperatures tested and were surveyed about their knowledge and beliefs related to these safety behaviors. We found that 40% of households had working SAs on every level and 57% had safe hot water temperatures. Perceived severity and self-efficacy were significantly associated with SA coverage, whereas perceived susceptibility and beliefs about benefits were significantly associated with safe hot water temperatures. This study demonstrates the need to increase the number of homes with working SAs and safe hot water temperatures. Messages focused on a safe home environment could communicate the ease and harm reduction features of SAs and benefits and risk reduction features of safe hot water temperatures.

Abstract
This study aimed to compare an in-class Seniors on the MOVE (Mature Operators Vehicular Education) interactive multi-session driving curriculum with a self-guided MOVE curriculum for older adults. Using a two group randomized design, we sought to determine if there are between-group differences in older drivers' knowledge and safety behaviors among participants. Forty-four participants with an average age of 79 years (SD=7.1) were randomly assigned to the original MOVE program (SOM-A) or a lower resource (SOM-B) self-guided intervention. SOM-A is a four session program designed to improve older drivers safety knowledge and better understand skills for safer driving. SOM-B is a self-guided program with one required in-class session and one optional session. Subsequent to completion of both curricula, participants were offered CarFit, a comprehensive check of how well a senior driver and their vehicle work together. Baseline, post-intervention and 6-month follow up questionnaires were completed by participants. We found significant differences (p=.01) in the mean driving safety knowledge scores when comparing participants in SOM-A (3.7, SD 2.0) to those in SOM-B (0.87, SD 2.6). With regard to behavioral outcomes, we focused on always wearing a seatbelt, talking with a health care provider about driving ability, and sitting 10-12 inches from the steering wheel. The vast majority of participants reported always wearing their seat belts (SOM-A 100%, SOM-B 92%, p=1.0), and very few reported talking with their doctors (SOM-A Baseline--0%, Follow up 1--0%, p=n/a). Mean behavior change scores for participants sitting 10-12 inches from the steering wheel were significantly more likely among SOM-A (mean=.65, SD=.5) participants than those in SOM-B (mean=.29, SD=.5, p=.01) at first follow-up. Taken together, these findings suggest that the more intensive program is more effective and that driving safety programs focused on behaviors to self evaluate driving abilities continue to be needed to help older drivers remain safer on the road as they age. The involvement of health care providers in such efforts may be an untapped potential.

Abstract
OBJECTIVE This study set out to determine if cetuximab treatment increases the risk of wound healing complications when combined with radiation therapy. METHOD We performed a retrospective chart review of head and neck cancer patients who received salvage neck dissections between 1999 and 2007, at two academic tertiary care centres. Complications from wound healing were compared between radiation and combined therapy groups. RESULTS A total of 35 patients received radiation (n=20) or combined radiation and cetuximab therapy (n=15) prior to neck dissection. The treatment groups were similar in regard to demographic and primary tumour-related characteristics. The time between treatment and salvage neck dissection did not differ between the radiation (3.9 months) and combination treatment (3.0 months) groups (p=0.15). Wound healing complications occurred in 13% (2/15) of the patients treated with radiation and cetuximab and there were no complications in patients who received radiation alone (p=0.20). CONCLUSION Cetuximab did not significantly increase the risk of post-surgical wound complications, although a higher absolute number of wound complications was observed in the group treated with cetuximab and radiation therapy, compared with the group treated with radiation alone. CONFLICT OF INTEREST This work was supported by a grant from the National Institute of Health (2T32 CA091078-06). One of the authors, JAB, is an occasional consultant and honoraria for ImClone and Bristol-Meyers Squibb.

Abstract
AIMS To compare agreement level and identify reasons for disagreement between grading of mydriatic digital photographs in a diabetic retinopathy screening service and hospital eye service biomicroscopy grading. METHODS Structured examination findings leading to automatically calculated National Screening Committee grades recorded on an electronic medical record system in the hospital eye service at the first clinic visit after diabetic retinopathy screening service referral between April 2006 and November 2007 were retrospectively compared with the grade at the screening visit that prompted referral. In cases of disagreement, screening images were reviewed. RESULTS Data on 452 eyes (226 patients) were analysed. For retinopathy, hospital eye service slit-lamp biomicroscopy grades were: R0 (no diabetic retinopathy) in 63 eyes; R1 (background retinopathy) in 251 eyes; R2 (pre-proliferative) in 129 eyes and R3 (proliferative) in nine eyes. Diabetic retinopathy screening service grades were in agreement in 350 eyes (77.4%), showed a lower grade in 59 eyes and a higher grade in 43. Agreement was moderate (κ=0.60). The most common reason for disagreement was overgrading of R1 by clinicians. Hospital eye service biomicroscopy maculopathy grades were: M0 (no maculopathy) in 366 eyes and M1 (maculopathy) in 86 eyes. Diabetic retinopathy screening service grades were in agreement in 327 eyes (72.3%), showed a lower grading in five eyes and a higher grade in 120 eyes. Agreement was moderate (κ=0.41). The commonest cause for disagreement was clinicians failing to identify fine macular exudates. CONCLUSIONS This study of routine clinical services demonstrates moderate agreement between non-medical grading of mydriatic digital retinal photography images and hospital slit-lamp biomicroscopy grading of patients referred with diabetic retinopathy. The majority of errors in grading were attributable to errors by hospital doctors, usually in the direction of under-grading which could be a potential source of clinical risk if treatment is delayed.

Abstract
The emergence of high bandwidth public wireless networks and miniaturized personal mobile devices give rise to new mobile healthcare services. To this end, the MobiHealth system provides highly customizable vital signs tele-monitoring and tele-treatment system based on a body area network (BAN) and a mobile health care (m-health) service platform utilizing next generation public wireless networks. The developed system allows the incorporation of diverse medical sensors via wireless connections, and the live transmission of the measured vital signs to healthcare providers as well as real-time feedback to the patient. Since 2002 the system has undergone substantial development in consecutive EU and national research projects. Diverse trials with different healthcare scenarios and patient groups in different European countries have been conducted in all projects. These have been performed to test the service and the network infrastructure including its suitability for m-health applications.

Abstract
INTRODUCTION Emergency department (ED) attendances and subsequent hospital admissions are rising in the United Kingdom. The reasons for this are unclear but may relate to recent changes in primary care and public perception. The actions taken by patients or their relatives before emergency hospital admission, the reasons for these actions and their outcome were determined. METHODS Adult patients admitted to an inner city teaching hospital with a medical or surgical illness were interviewed using a semistructured questionnaire. Data were collected and analyzed regarding the actions taken before arrival at hospital, the reasons for taking these actions, their outcome and future intentions. 200 patients were interviewed. RESULTS Direct attendance at the ED was more common when help was sought by bystanders or persons known only slightly to the patient (p = 0.03). 57 patients (28.5%) attended the ED directly, 45 of whom dialled 999 for an emergency ambulance. Most patients who attended the ED directly did so as a result of the perceived severity or urgency of their condition and there was incomplete awareness of the out-of-hours GP service. CONCLUSION The majority of adult patients who are admitted to hospital with an acute illness seek professional help from primary care in the first instance. Those who attend the ED generally perceive their problem as more urgent or severe, or have an ambulance called on their behalf. The shift towards ED care appears partly driven by changes in general practice and unfamiliarity with the new arrangements for out-of-hours primary care provision.

Abstract
516 Background: Evidence suggests that docetaxel is more effective than paclitaxel, and paclitaxel is more effective when given weekly than every 3 weeks in metastatic breast cancer (BC). Methods: Eligibility included axillary lymph node positive or high-risk (tumor at least 2 cm) node-negative BC. All patients received 4 cycles of AC (doxorubicin 60 mg/m2 and cyclophosphamide 600 mg/m2) every 3 weeks, followed by either: (1) paclitaxel 175 mg/m2 every 3 weeks × 4 (P3), (2) paclitaxel 80 mg/m2 weekly × 12 (P1), (3) docetaxel 100 mg/m2 every 3 weeks × 4 (D3), or (4) docetaxel 35 mg/m2 weekly × 12 (D1). The primary comparisons included taxane (P vs. D) and schedule (every 3 weeks vs. weekly), and secondary comparisons included P3 vs. other arms. The trial had 86% power to detect a 17.5% decrease in disease-free survival (DFS) for either primary comparison, and 80% power to detect a 22% decrease for the secondary comparisons (2-sided nomimal 5% level tests corrected for multiple comparisons). Results: A total of 4,950 eligible patients were accrued. There was no difference in the primary comparisons afer 856 DFS events and 483 deaths after a median follow-up of 46.5 months at the 4th interim analysis ( www.sabcs.org , abstract 48). This is the final pre-specified analysis for the primary comparisons after 1,042 DFS events and 650 deaths (with 1,020 DFS events at this time, to be updated at the meeting). After a median followup of 60.2 months, there remains no significant difference in the hazard ratio (HR) for the taxane (1.02; p=0.73) or schedule (1.07; p=0.30) (as in the first analysis). In secondary comparisons of the standard arm (P3) with the other arms (HR > 1 favoring the experimental arms), the HRs were 1.30 (p = 0.003) for arm P1, 1.24 (p=0.02) for arm D3, and 1.09 (p=0.33) for arm D1. Analysis of interaction by hormone-receptor status will be presented. The incidence of worst grade toxicity (grade 3/4) was 24%/6% for arm P3, 24%/3% for arm P1, 21%/50% for arm D3, and 38%/6% for arm D1. Conclusions: There were no differences in DFS when comparing taxane or schedule overall. DFS was significantly improved in the weekly paclitaxel and every 3-week docetaxel arms compared with the every 3-week paclitaxel arm. [Table: see text]

Abstract
BACKGROUND Deliberate self-harm can be costly, in terms of treatment and subsequent suicide. Any intervention that reduces episodes of self-harm might therefore have a major impact on the costs incurred by service providers and the productivity losses due to illness or premature death. METHOD Four hundred and eighty patients with a history of recurrent deliberate self-harm were randomized to manual-assisted cognitive behaviour therapy (MACT) or treatment as usual. Economic data were collected from patients at baseline, 6 and 12 months, and these data were complete for 397 patients. Incremental cost-effectiveness was explored using the primary outcome measure, proportion of patients having a repeat episode of deliberate self-harm, and quality of life. The uncertainty surrounding costs and effects was represented using cost-effectiveness acceptability curves. RESULTS Differences in total cost per patient were statistically significant at 6 months in favour of MACT (pounds sterling -897, 95 % CI -1747 to -48, P=0.04), but these differences did not remain significant at 12 months (pounds sterling -838, 95% CI -2142 to 466, P=0.21). Nevertheless, exploration of the uncertainty surrounding these estimates suggests there is >90% probability that MACT is a more cost-effective strategy for reducing the recurrence of deliberate self-harm in this population over 1 year than treatment as usual. The results for quality of life were not conclusive. CONCLUSION Cost-effectiveness acceptability curves demonstrate that, based on the evidence currently available, to reject MACT on traditional grounds of statistical significance and to continue funding current practice has <10% chance of being the correct decision in terms of cost-effectiveness.

Abstract
BACKGROUND We carried out a large randomized trial of a brief form of cognitive therapy, manual-assisted cognitive behaviour therapy (MACT) versus treatment as usual (TAU) for deliberate self-harm. METHOD Patients presenting with recurrent deliberate self-harm in five centres were randomized to either MACT or (TAU) and followed up over 1 year. MACT patients received a booklet based on cognitive behaviour therapy (CBT) principles and were offered up to five plus two booster sessions of CBT from a therapist in the first 3 months of the study. Ratings of parasuicide risk, anxiety, depression, social functioning and global function, positive and negative thinking, and quality of life were measured at baseline and after 6 and 12 months. RESULTS Four hundred and eighty patients were randomized. Sixty per cent of the MACT group had both the booklet and CBT sessions. There were seven suicides, five in the TAU group. The main outcome measure, the proportion of those repeating deliberate self-harm in the 12 months of the study, showed no significant difference between those treated with MACT (39%) and treatment as usual (46%) (OR 0.78, 95% CI 0.53 to 1.14, P=0.20). CONCLUSION Brief cognitive behaviour therapy is of limited efficacy in reducing self-harm repetition, but the findings taken in conjunctin with the economic evaluation (Byford et al. 2003) indicate superiority of MACT over TAU in terms of cost and effectiveness combined.

Abstract
This study focuses on farmers' perceptions of roadway safety and reviews specific and pertinent North Carolina rural road crash data to evaluate their perceptions and concerns. A survey was mailed to 1,357 prospective participants throughout North Carolina. Of these, 656 (48.3%) North Carolina farmers completed and returned the survey. The study revealed that while the majority of respondents took a number of specific safety measures to ensure their safety while driving their tractor on rural roads, most believed that driving their tractor on rural roads was more dangerous than it was five years ago. Few respondents believed that laws governing tractors on rural roads are well known by urban residents. While a majority of the respondents would support a law to mandate the use of a slow-moving vehicle (SMV) emblem on the back of slow-moving farm equipment, a majority also believed that a more effective way to mitigate potential crashes would be to ensure that all farm vehicles had blinking or flashing lights, that diamond-shaped caution signs depicting a tractor were posted on roadways with frequent tractor traffic, and that roadway shoulders were created or widened on roads with heavy farm traffic so that tractors could move off the roadway. Only 22% of respondents felt safe driving their tractor on rural roadways in North Carolina. Most respondents felt that the biggest problem with roadway safety was the lack of respect and increased speed of other drivers. Recent data indicate that in crashes involving farm vehicles, citations were issued to 34% of the non-farm vehicle operators and 24% to farm vehicle operators. For those driving non-farm vehicle who were deemed at fault, 66% were cited for failure to reduce speed. For those driving farm vehicles, the most frequent citation involved the lack of safe movement.

Abstract
High-dose chemotherapy with autologous stem cell support (HDC-ASCS) can produce high complete remission rates in patients with metastatic breast cancer (MBC). However, the majority of those so treated will relapse within 3 years. The ability of such patients to tolerate further myelosuppressive chemotherapy may be limited and the best therapy is undefined. In this retrospective study we assessed the role of capecitabine as initial therapy after relapse. Ten patients (median age = 47 years; oestrogen receptor-positive, n = 4; visceral disease, n = 6; prior anthracycline, n = 8, prior taxanes, n = 10), whose disease progressed at a median of 246 days (range 69-480) after HDC-ASCS and who were treated with capecitabine (2500 mg/m2 per day for 2 weeks of a 3-week cycle) as initial therapy for relapse, were assessed retrospectively for response and toxicity. They received a median of eight cycles (range 4-24) of capecitabine. The toxicities encountered while receiving capecitabine were: hand-foot syndrome (grade 1, n = 3; grade 2, n = 4; grade 3, n = 1); diarrhoea (grade 1, n = 1; grade 2, n = 3); nausea (n = 2) and fatigue (n = 5). Haematological toxicity was seen in only one patient. No patient required hospitalization for toxicity. Three achieved a complete remission, four a partial remission and three disease stabilization. After a median follow-up of 183 days from commencing capecitabine (range 97-540), all patients were alive and five were in remission. Five progressed after remissions that lasted between 63 and 252 days. Oral capecitabine is an active and well-tolerated agent when used alone as first-line therapy in patients who have relapsed after HDC-ASCS for MBC.

Abstract
An insertion-sequence of prokaryotic origin was detected in a genomic clone obtained from a Phaseolus vulgaris bacterial artificial chromosome (BAC) library. This BAC clone, characterized as part of a contig constructed near a virus resistance gene, exhibited restriction fragment length polymorphism with an overlapping clone of the contig. Restriction analysis of DNA obtained from individual colonies of the stock culture indicated the presence of a mixed population of wild-type and insertional mutants. Sequence analysis of both members of the population revealed the presence of IS 10R, an insertion-sequence from Escherichia coli. A BLAST search for IS 10-like sequences detected unexpected homologies with a large number of eukaryotic sequences from Homo sapiens, Arabidopsis thaliana, Drosophila melanogasterand Caenorhabditis elegans. Southern analysis of a random sample of BAC clones failed to detect IS 10 in the BAC DNA. However, prolonged sub-culturing of a set of 15 clones resulted in transposition into the BAC DNA. Eventually, all cultures acquired a 2.3-kb fragment that hybridized strongly with IS 10. Sequence analysis revealed the presence of a preferred site for transposition in the BAC vector. These results indicate that a large number, if not all, of the BAC libraries from different organisms are contaminated with IS 10R. The source of this element has been identified as the DH10B strain of E. coli used as the host for BAC libraries.

Abstract
Fatigue is a major complaint among cancer patients, yet it is unknown whether cancer-related fatigue experienced during the day relates to sleep/wake cycles or to the quality and quantity of sleep obtained at night. Although it is not well defined or well understood at present, cancer-related fatigue is generally regarded as a form of tiredness that does not improve following rest or sleep. Objectively recorded sleep and biological rhythms have not been well investigated in these patients, but it appears that most cancer patients may in fact not be getting a good night's sleep. Evidence is accumulating that sleep is often disturbed in cancer patients, probably owing to a variety of causes. We posit that some degree of cancer-related fatigue experienced during the day may relate to sleep/wake cycles or to the quality and quantity of sleep obtained at night. Different components or dimensions of fatigue (physical, attentional/cognitive, emotional/affective, etc.) are probably associated in some way with disrupted sleep and desynchronized sleep/wake rhythms. These associations may change in measurable ways prior to treatment, during treatment and after treatment completion. In cancer patients, as in other medically ill patients, sleep that is inadequate or unrefreshing may be important not only to the expression of fatigue, but to the patients' quality of life and their tolerance to treatment, and may influence the development of mood disorders and clinical depression. This review summarizes the state of the literature on fatigue, sleep and circadian rhythms.

Abstract
Fourteen pairs of explanted low contact stress (LCS) tibial interface components: six rotating platform (RP), six meniscal (MN) and two anterior-posterior (AP) glide designs, have been analysed with particular attention paid to the condition of the tibial counterfaces. The average surface roughness, Ra, for the tibial trays ranged from 0.01 to 0.087 micron, significantly greater than the unworn control measurement of 0.008 micron. The scratch geometry analysis showed that the scratch peaks were found to be consistently of a lower aspect ratio than the scratch valleys and under 1 micron in height (average asperity height Rp = 0.52 micron, aspect ratio delta p = 0.01, average asperity depth Rv = 1.10 microns, delta v = 0.05). The largest scratches were 3-4 microns in both Rp and Rv. In vitro tests have shown that ultra-high molecular weight polyethylene (UHMWPE) wear increases in the presence of counterface scratches perpendicular to the direction of motion. In these explants, the unidirectional motion produced scratches parallel to the direction of sliding which is predicted to produce a smaller increase in UHMWPE wear. Other designs in mobile bearing knees have less constrained motion at the tibial counterface and this has been shown to accelerate wear; it may also lead to a further increase in wear in the presence of third body scratches. It may be possible in future knee designs to reduce this type of wear damage by introducing alternative materials or coatings which are more resistant to scratching and surface roughening.
