Abstract
PURPOSE/OBJECTIVE(S) The optimal sequencing of stereotactic ablative body radiotherapy (SABR) with anti-PD1 checkpoint blockade is unknown. The purpose of SABRseq was to assess the toxicity of the combination of SABR delivered either before or after the commencement of pembrolizumab. The central hypothesis is that the treatment combination will have a safety profile that is clinically acceptable and demonstrate anti-tumor efficacy. Furthermore, we hypothesize that differences in systemic immune activation will be observed between treatment arms. MATERIALS/METHODS This was a single institutional phase Ib randomized clinical trial (Trial ID NCT03307759). Eligible patients had metastatic NSCLC, ECOG performance 0-1, and had not received prior checkpoint immunotherapy, high-dose radiation (>36 Gy) within 6 months, or either systemic or radiation therapy within 4 weeks of randomization. Eligible patients had either TPS≥50% PD-L1 expression in the first-line or TPS≥1% PD-L1 expression with prior chemotherapy exposure. Patients were randomized to SABR before the commencement of pembrolizumab [ARM1] or SABR commencing after pembrolizumab [ARM2]. SABR was delivered in a single fraction of 18-20 Gy to 1-3 lesions. The primary endpoint was treatment-related adverse events (AE's) related to SABR and/or pembrolizumab. Secondary endpoints included best overall response (BOR), overall survival (OS), and progression-free survival (PFS). Translational objectives included the evaluation of longitudinal changes in immunological cellular subsets within peripheral blood to explore changes in systemic immunity and circulating tumor DNA (ctDNA) dynamics. RESULTS Between December 2017 and December 2019, 13 patients were randomized. The median follow-up was 37 months. The study was closed early due to poor accrual. Median age was 66 years, with 11 patients (84%) having adenocarcinoma. Nine (69%) were enrolled in the first-line setting. The median [range] number of lesions was 6 [3-11]. The median [range] cycles of pembrolizumab delivered in ARM 1 was 13 [12-32] and ARM 2 was 9 [3-34]. Grade 3 treatment-related AEs were experienced in 0 of 5 patients in ARM1 and in 1 of 8 patients in ARM 2 (hyperglycemia). There were no grade 4 or 5 adverse events reported. The BOR by both RECIST and iRECIST criteria was CR in one patient, PR in seven patients, SD in five patients. Median (95% Cis) PFS was 12.4 months (6.3-21.0), and median (95% Cis) OS was 47.1 months (12.6-not reached; 2-year point estimate 62% [31-82]). Mass cytometry was used on serial peripheral blood samples to examine changes in the frequency of immune cells, changes in T cell activation, differentiation and functional polarization state. Targeted sequencing was performed to assess ctDNA. Translational outcomes will be presented. CONCLUSION There was no evidence of a concerning safety signal from either SABR before or after start of pembrolizumab. The combination demonstrated activity with promising PFS and OS and is worthy of evaluation in larger randomized trials.

Abstract
Abstract
Background
Lifetime risks of cardiovascular (CV) and renal diseases are high, particularly in type 2 diabetes (T2D), but rarely studied together, and relative disease contributions are unknown. Knowledge of lifetime risk of cardiovascular-renal disease (CVRD) will better reflect disease burden in T2D.
Purpose
To investigate the lifetime risks (LTRs) of composite and individual components of major adverse reno-cardiovascular events, MARCE in T2D patients.
Method
In a population-based cohort study using national electronic health records, we studied 473399 individuals aged 45–99 years with T2D in England 2007–2018. The LTR of composite and individual components of MARCE (including CV death and CVRD: heart failure, HF; chronic kidney disease stage 3 and above, CKD; myocardial infarction, MI; stroke or peripheral artery disease, PAD) were estimated. LTRs by baseline CVRD comorbidity status were compared with individuals free from CVRD at baseline, accounting for the competing risk of death.
Results
Among T2D patients aged ≥45 years, the LTR of MARCE was 80% for individuals free from CVRD at baseline. LTR of MARCE was 97%, 93%, 98%, 89% and 91% for individuals with specific CVRD comorbidities for HF, CKD, MI, stroke and PAD, respectively at baseline. Within the CVRD-free cohort, LTR of CKD was highest at 54%, followed by CV death (41%), HF (29%), stroke (20%), MI (19%) and PAD (9%). Compared to CVRD-free, HF, MI and CKD at baseline were associated with the highest LTR of MARCE and its component diseases (Table).
Conclusion
The lifetime risk of CV disease and CKD in T2D patients is estimated to be over 60% and 50% respectively (1–3). When considered together, the LTR of MARCE is 80% in CVRD-free T2D patients, while nearly all those with T2D and HF will develop MARCE over their lifetime. Of the individual components of MARCE, LTR of CKD and HF were the highest among CVRD-free T2D patients. Preventive measures in T2D patients should be a priority in clinical practice to mitigate the burden of these complications.

Abstract
Background Women who gain too much weight in pregnancy are at increased risk of disease and of having children with increased risk. Interventions to improve health behaviours are usually designed for a general population of pregnant women, and trial outcomes show an average impact that does not represent the differences between individuals. To inform the development of future interventions, this study explored the factors that influenced women’s diet and physical activity during pregnancy and aimed to identify the needs of these women with regards to lifestyle support. Methods Women who completed a trial of vitamin D supplementation and nurse support in pregnancy were invited to take part in an interview. Seventeen women were interviewed about their lifestyles during pregnancy, the support they had, and the support they wanted. Interview transcripts were coded thematically and analysed to understand the factors that influenced the diets and physical activity levels of these women and their engagement with resources that could provide support. Results Women identified barriers to eating well or being physically active, and pregnancy-specific issues like nausea and pain were common. Women’s interest in maintaining a healthy lifestyle and their engagement with lifestyle support was related to the extent to which they self-identified as healthy people. Health-disengaged women were disinterested in talking about their lifestyles while health-focused women did not feel that they needed extra support. Women between these ends of the ‘health identity’ spectrum were interested in improving their health, and were able to identify barriers as well as sources of support. Conclusions Lifestyle interventions in pregnancy should be adapted to meet the needs of individuals with different health identities, and encouraging a change in health identity may be one way of supporting sustained change in health behaviours.

Abstract
The majority of research on factors associated with women participation in physical activity (PA) has been in developed countries with limited research in developing countries. Few women in Malaysia are active at the recommended levels for health, and activity rates are less than developed countries. Little research has focused specially on physically active Malaysian women and the factors that contribute to them becoming and staying active in PA programs. This lack of knowledge hinders the tailored development and implementation of PA programs to meet their needs. The aim of this study was to identify the factors of participation in PA programs for Malaysian women. The social-ecological model was used to investigate and theme the factors. Focus group discussion was conducted with participants in six PA programs targeted specifically to women. Thirty-seven women were involved in the focus group discussion, with ages ranging from 19 to 82 years. Inductive and deductive content analysis was conducted from verbatim transcripts using NVivo. Inductive content analysis allowed raw data and second-order themes to emerge. Findings revealed social support structures, tailored programs for women, and location were key contributors that encouraged women to participate in these programs. The similarity in contributors between women in non-western and western countries signifies a prime opportunity for bi-lateral relationships to be formed to enable the enhancement of program development relevant to different ethnicities and cultures within or across countries.

Abstract
Background. Experimental studies suggest that mechanical cell washing to remove pro-inflammatory components that accumulate in the supernatant of stored donor red blood cells (RBCs) might reduce inflammation and organ injury in transfused patients. Methods. Cardiac surgery patients at increased risk of large-volume RBC transfusion were eligible. Participants were randomized to receive either mechanically washed allogenic RBCs or standard care RBCs. The primary outcome was serum interleukin-8 measured at baseline and at four postsurgery time points. A mechanism substudy evaluated the effects of washing on stored RBCs in vitro and on markers of platelet, leucocyte, and endothelial activation in trial subjects. Results. Sixty adult cardiac surgery patients at three UK cardiac centres were enrolled between September 2013 and March 2015. Subjects received a median of 3.5 (interquartile range 2–5.5) RBC units, stored for a mean of 21 (sd 5.2) days, within 48 h of surgery. Mechanical washing reduced concentrations of RBC-derived microvesicles but increased cell-free haemoglobin concentrations in RBC supernatant relative to standard care RBC supernatant. There was no difference between groups with respect to perioperative serum interleukin-8 values [adjusted mean difference 0.239 (95% confidence intervals −0.231, 0.709), P=0.318] or concentrations of plasma RBC microvesicles, platelet and leucocyte activation, plasma cell-free haemoglobin, endothelial activation, or biomarkers of heart, lung, or kidney injury. Conclusions. These results do not support a hypothesis that allogenic red blood cell washing has clinical benefits in cardiac surgery. Clinical trial registration. ISRCTN 27076315.

Abstract
BACKGROUND During the first 4 months of age, approximately 20% of infants cry a lot without an apparent reason. Most research has targeted the crying, but the impact of the crying on parents, and subsequent outcomes, need to receive equal attention. This study reports the findings from a prospective evaluation of a package of materials designed to support the well-being and mental health of parents who judge their infant to be crying excessively. The resulting "Surviving Crying" package comprised a website, printed materials, and programme of Cognitive Behaviour Therapy-based support sessions delivered to parents by a qualified practitioner. It was designed to be suitable for United Kingdom (UK) National Health Service (NHS) use. METHODS Parents were referred to the study by 12 NHS Health Visitor/Community Public Health Nurse teams in one UK East Midlands NHS Trust. Fifty-two of 57 parents of excessively crying babies received the support package and completed the Edinburgh Postnatal Depression Scale and Generalized Anxiety Disorder-7 anxiety questionnaire, as well as other measures, before receiving the support package and afterwards. RESULTS Significant reductions in depression and anxiety were found, with numbers of parents meeting clinical criteria for depression or anxiety halving between baseline and outcome. These improvements were not explained by reductions in infant crying. Reductions also occurred in the number of parents reporting the crying to be a large or severe problem (from 28 to 3 parents) or feeling very or extremely frustrated by the crying (from 31 to 1 parent). Other findings included increases in parents' confidence, knowledge of infant crying, and improvements in parents' sleep. CONCLUSIONS The findings suggest that the Surviving Crying package may be effective in supporting the well-being and mental health of parents of excessively crying babies. Further, large-scale controlled trials of the package in NHS settings are warranted.

Abstract
BACKGROUND Research investigating interprofessional practice (IPP) frameworks has predominately focused on the service delivery of IPP or educating practitioners through interprofessional education. Minimal research has addressed client outcomes or the experience of clients with IPP in real world contexts. In this paper, we explore the experience of seven participants in the ActivePlus program, an IPP-based smoking cessation intervention combined with physical activity promotion. METHODS Participants informed on their program experiences through post-program in-depth interviews. A thematic analysis drew out themes pertaining to participant experiences of the joint practice element of the IPP model of care. RESULTS Analysis identified two major themes: the joint practice experience, and the client-centered approach of the IPP model of care. Participants reflected on the ways that having two health practitioners in joint sessions benefited their intervention experience, as well as providing some critical feedback. Participants also reported observing and valuing aspects of client-centered practice that strengthened the rapport within the practitioner-client team and aided their behaviour change progress. The client-centered practice was instrumental in overcoming initial teething issues with joint session delivery and alleviating pre-program participant concerns about being outnumbered by multiple practitioners. CONCLUSION Despite some early teething issues, participants reported a positive acceptance of the IPP and joint session delivery model, which added value to the overall ActivePlus program. Results from this research can provide practitioners with a client perspective on the key aspects they perceive as important in IPP joint session delivery. Further investigation into the client perception in similar interventions is recommended with larger samples and non-clinical groups.

Abstract
The emergence of Clostridium difficile as a significant human diarrheal pathogen is associated with the production of highly transmissible spores and the acquisition of antimicrobial resistance genes (ARGs) and virulence factors. Unlike the hospital-associated C. difficile RT027 lineage, the community-associated C. difficile RT078 lineage is isolated from both humans and farm animals; however, the geographical population structure and transmission networks remain unknown. Here, we applied whole-genome phylogenetic analysis of 248 C. difficile RT078 strains from 22 countries. Our results demonstrate limited geographical clustering for C. difficile RT078 and extensive coclustering of human and animal strains, thereby revealing a highly linked intercontinental transmission network between humans and animals. Comparative whole-genome analysis reveals indistinguishable accessory genomes between human and animal strains and a variety of antimicrobial resistance genes in the pangenome of C. difficile RT078. Thus, bidirectional spread of C. difficile RT078 between farm animals and humans may represent an unappreciated route disseminating antimicrobial resistance genes between humans and animals. These results highlight the importance of the "One Health" concept to monitor infectious disease emergence and the dissemination of antimicrobial resistance genes.

Abstract
Inter-laboratory reproducibility of Matrix Assisted Laser Desorption Time-of-Flight Mass Spectrometry (MALDI-TOF MS) of anaerobic bacteria has not been shown before. Therefore, ten anonymized anaerobic strains were sent to seven participating laboratories, an initiative of the European Network for the Rapid Identification of Anaerobes (ENRIA). On arrival the strains were cultured and identified using MALDI-TOF MS. The spectra derived were compared with two different Biotyper MALDI-TOF MS databases, the db5627 and the db6903. The results obtained using the db5627 shows a reasonable variation between the different laboratories. However, when a more optimized database is used, the variation is less pronounced. In this study we show that an optimized database not only results in a higher number of strains which can be identified using MALDI-TOF MS, but also corrects for differences in performance between laboratories.

Abstract
Gram-positive anaerobic cocci (GPAC) account for 24%-31% of the anaerobic bacteria isolated from human clinical specimens. At present, GPAC are under-represented in the Biotyper MALDI-TOF MS database. Profiles of new species have yet to be added. We present the optimization of the matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF MS) database for the identification of GPAC. Main spectral profiles (MSPs) were created for 108 clinical GPAC isolates. Identity was confirmed using 16S rRNA gene sequencing. Species identification was considered to be reliable if the sequence similarity with its closest relative was ≥98.7%. The optimized database was validated using 140 clinical isolates. The 16S rRNA sequencing identity was compared with the MALDI-TOF MS result. MSPs were added from 17 species that were not yet represented in the MALDI-TOF MS database or were under-represented (fewer than five MSPs). This resulted in an increase from 53.6% (75/140) to 82.1% (115/140) of GPAC isolates that could be identified at the species level using MALDI-TOF MS. An improved log score was obtained for 51.4% (72/140) of the strains. For strains with a sequence similarity <98.7% with their closest relative (n = 5) or with an inconclusive sequence identity (n = 4), no identification was obtained by MALDI-TOF MS or in the latter case an identity with one of its relatives. For some species the MSP of the type strain was not part of the confined cluster of the corresponding clinical isolates. Also, not all species formed a homogeneous cluster. It emphasizes the necessity of adding sufficient MSPs of human clinical isolates.

Abstract
Introduction It has been suggested that removal of proinflammatory substances that accumulate in stored donor red cells by mechanical cell washing may attenuate inflammation and organ injury in transfused cardiac surgery patients. This trial will test the hypotheses that the severity of the postoperative inflammatory response will be less and postoperative recovery faster if patients undergoing cardiac surgery receive washed red cells compared with standard care (unwashed red cells). Methods and analysis Adult (≥16 years) cardiac surgery patients identified at being at increased risk for receiving large volume red cell transfusions at 1 of 3 UK cardiac centres will be randomly allocated in a 1:1 ratio to either red cell washing or standard care. The primary outcome is serum interleukin-8 measured at 5 postsurgery time points up to 96 h. Secondary outcomes will include measures of inflammation, organ injury and volumes of blood transfused and cost-effectiveness. Allocation concealment, internet-based randomisation stratified by operation type and recruiting centre, and blinding of outcome assessors will reduce the risk of bias. The trial will test the superiority of red cell washing versus standard care. A sample size of 170 patients was chosen in order to detect a small-to-moderate target difference, with 80% power and 5% significance (2-tailed). Ethics and dissemination The trial protocol was approved by a UK ethics committee (reference 12/EM/0475). The trial findings will be disseminated in scientific journals and meetings. Trial registration number ISRCTN 27076315.

Abstract
The applied model of mental imagery use proposed an interaction effect between imagery type and imagery ability. This study had two aims: (a) the examination of imagery ability as a moderating variable between imagery type and dispositional flow, and (b) the testing of alternative mediation models. The sample consisted of 367 athletes from Scotland and Australia, who completed the Sport Imagery Questionnaire, Sport Imagery Ability Questionnaire, and Dispositional Flow Scale-2. Hierarchical regression analysis showed direct effects of imagery use and imagery ability on flow, but no significant interaction. Mediation analysis revealed a significant indirect path, indicating a partially mediated relationship (P = 0.002) between imagery use, imagery ability, and flow. Partial mediation was confirmed when the effect of cognitive imagery use and cognitive imagery ability was tested, and a full mediation model was found between motivational imagery use, motivational imagery ability, and flow. The results are discussed in conjunction with potential future research directions on advancing theory and applications.

Abstract
An international collaborative study was organised jointly by the World Health Organization (WHO)/National Institute for Biological Standards and Control (NIBSC), the United States Pharmacopeia (USP) and the European Directorate for the Quality of Medicines & HealthCare (EDQM/Council of Europe) for the establishment of harmonised replacement endotoxin standards for these 3 organisations. Thirty-five laboratories worldwide, including Official Medicines Control Laboratories (OMCLs) and manufacturers enrolled in the study. Three candidate preparations (10/178, 10/190 and 10/196) were produced with the same material and same formulation as the current reference standards with the objective of generating a new (3(rd)) International Standard (IS) with the same potency (10 000 IU/vial) as the current (2(nd)) IS, as well as new European Pharmacopoeia (Ph. Eur.). and USP standards. The suitability of the candidate preparations to act as the reference standard in assays for endotoxin performed according to compendial methods was evaluated. Their potency was calibrated against the WHO 2(nd) IS for Endotoxin (94/580). Gelation and photometric methods produced similar results for each of the candidate preparations. The overall potency estimates for the 3 batches were comparable. Given the intrinsic assay precision, the observed differences between the batches may be considered unimportant for the intended use of these materials. Overall, these results were in line with those generated for the establishment of the current preparations of reference standards. Accelerated degradation testing of vials stored at elevated temperatures supported the long-term stability of the 3 candidate preparations. It was agreed between the 3 organisations that batch 10/178 be shared between WHO and EDQM and that batches 10/190 and 10/196 be allocated to USP, with a common assigned value of 10 000 IU/vial. This value maintains the continuity of the global harmonisation of reference materials and unitage for the testing of endotoxins in parenteral pharmaceutical products. Based on the results of the collaborative study, batch 10/178 was established by the European Pharmacopoeia Commission as the Ph. Eur. Endotoxin Biological Reference Preparation (BRP) batch 5. The same batch was also established by the Expert Committee on Biological Standardisation (ECBS) of WHO as the WHO 3(rd) IS for Endotoxin. Batch 10/190 was adopted as the USP Endotoxin Reference Standard, lot H0K354 and vials from this same batch (10/190) will serve as the United States Food and Drug Administration (USFDA) Endotoxin Standard, EC-7.

Abstract
AIM The study aimed to examine 1) the validity of the nine-factor flow model in tennis competition; 2) differences in flow state between athletes who won or lost their competition match; 3) the link between flow and subjective performance; and 4) flow dimensions as predictors of performance outcome METHODS The sample consisted of 188 junior tennis players (115 male, 73 female) between 12 and 18 years of age. Participants' performance was recorded during junior ranking-list tournaments. Following the completion of a tennis competition match, participants completed the Flow State Scale-2 and a subjective performance outcome measure. RESULTS Acceptable flow model fit indices of CFI, TLI, SRMR, and RMSEA were only found for winning athletes. The group of winning athletes scored significantly higher on all nine flow dimensions, except time transformation, than losing athletes, showing statistically significant differences for challenge-skills balance, clear goals, sense of control, and autotelic experience. Significant correlation coefficients were found between flow state and subjective performance assessments. The binary logistic regression revealed concentration on the task and sense of control to be significant predictors of performance outcome. The predictor variables explained 13% of the variance in games won. CONCLUSION The study showed that athletes who win or lose perceived flow state differently. Studies using retrospective assessments need to be aware that subjective experience could be biased by performance outcomes. Pinpointing psychological variables and their impact on ecologically valid measures, such as performance results, would support the development of effective intervention studies to increase performance in sport competition.

Abstract
Long-term persistent physical activity is important in the prevention of chronic diseases, but a large number of people do not participate in physical activity to obtain health benefits. The purpose of this study was to examine the motives and perceived barriers to long-term engagement in leisure time physical activity. Same-sex twin pairs (N=16, mean age 60) discordant for physical activity over 30 years were identified from the Finnish Twin Cohort. We evaluated participants' physical activity motivation with the 73-item Recreational Exercise Motivation Measure and assessed barriers to physical activity with a 25-item questionnaire. The characteristics of physical activity motivation and perceived barriers between the active and inactive co-twins were analysed using paired tests. Motives related to the sub-dimensions of enjoyment and physical fitness and psychological state were the most important reasons for participation in physical activity among all the twin individuals analysed. The sub-dimensions mastery (p=0.018, Cohen's d=0.76), physical fitness (p=0.029, Cohen's d=0.69), and psychological state (p=0.039, Cohen's d=0.65) differed significantly between active and inactive co-twins. More than half of the participants reported no reasons for not being physically active. If reasons existed, participation in physical activity was deterred mostly by pain and various health problems. This study found no differences in perceived barriers between active and inactive co-twins. We conclude from our results that the main factors promoting persistent leisure time physical activity were participants' wish to improve or maintain their physical skills or techniques, a feeling that exercise would improve their mental and physical health and that they found the activity enjoyable. This study helps us understand the importance of the role of motives and the minor role of perceived barriers for engagement in persistent physical activity.

Abstract
We report the development of new nanophosphor structures based on the Mn-doped ZnSeS material system to enhance the color properties, luminosity and efficiency of white LEDs. These structures have been demonstrated for phosphor-based white LED applications utilizing both blue and UV LED systems. Bandgap tuning for near UV (405 nm) and blue (460 nm) excitations are reported. Using various optimization procedures, we have produced ZnSe:Mn nanoparticles with an external quantum yield greater than 80%.

Abstract
117 Background: Endothelin-1 and the endothelin A (ETA) receptor have been implicated in prostate cancer progression in bone. Zibotentan, a specific ETA receptor antagonist, had a promising signal for prolonged overall survival (OS) in a phase II study of patients with CRPC and bone metastases who were pain free or mildly symptomatic for pain. The aim of this phase III study was to confirm the efficacy and safety of zibotentan in a similar but larger population. Methods: Patients with CRPC and bone metastases were randomized 1:1 to zibotentan 10 mg/day po or placebo, plus standard of care including chemotherapy. The primary endpoint was OS. Secondary endpoints included times to pain progression, chemotherapy use, new bone metastases, and safety. Efficacy endpoints were analyzed using a log-rank test. At least 263 deaths were required for formal analysis. If the true hazard ratio (HR) for zibotentan versus placebo was 0.67, the analysis would have 90% power to demonstrate a statistically significant effect in OS at the 5% level. Results: A total of 594 patients were randomized (299 to zibotentan; 295 to placebo). Baseline group demographics were similar. Mean age was ∼71 yrs, and 64% were Caucasian. Although median OS was longer in zibotentan-treated patients than those receiving placebo (median 24.5 vs 22.5 months), the difference did not reach significance (HR [95.2% confidence interval]; 0.87 [0.69–1.10]: P=0.240). No significant differences were observed for any secondary endpoints. The most commonly reported AEs in the zibotentan group, peripheral edema and headache, were consistent with the pharmacologic action of zibotentan as a vasodilator. Cardiac failure events, actively solicited following a phase II signal, were higher in the zibotentan group (any grade, 5.7%; Common Terminology Criteria for Adverse Events [CTCAE] grade ≥3, 3.0%) than placebo (any grade, 1.7%; CTCAE grade ≥3, 1.0%), but were manageable and reversible. Conclusions: In this placebo-controlled phase III trial treatment with zibotentan 10 mg/day did not lead to a significant improvement in OS in patients with CRPC and bone metastases. Zibotentan had an acceptable safety profile. [Table: see text]

Abstract
Healthcare-associated infections (HAIs) affect at least 300,000 patients annually in the UK and represent a significant, yet largely preventable, burden to healthcare systems. Hand hygiene by healthcare workers (HCWs) is the leading prevention measure, but compliance with good practice is generally low. The UK National Patient Safety Agency surveyed the public, inpatients, and HCWs, particularly frontline clinical staff and infection control nurses, in five acute care hospitals to determine whether they agreed that a greater level of involvement and engagement with patients would contribute to increased compliance with hand hygiene and reduce HAIs. Fifty-seven percent (302/530) of the public were unlikely to question doctors on the cleanliness of their hands as they assumed that they had already cleaned them. Forty-three percent (90/210) of inpatients considered that HCWs should know to clean their hands and trusted them to do so, and 20% (42/210) would not want HCWs to think that they were questioning their professional ability to do their job correctly. Most HCWs surveyed (178/254, 71%) said that HAI could be reduced to a greater or lesser degree if patients asked HCWs if they had cleaned their hands before touching them. Inviting patients to remind HCWs about hand hygiene through the provision of individual alcohol-based hand-rub containers and actively supporting an 'It's OK to ask' attitude were perceived as the most useful interventions by both patients and HCWs. However, further work is required to refute the myth among HCWs that patient involvement undermines the doctor- or HCW-patient relationship.

Abstract
Autologous chondrocyte implantation is an option in the treatment of full-thickness chondral or osteochondral injuries which are symptomatic. The goal of surgery and rehabilitation is the replacement of damaged cartilage with hyaline or hyaline-like cartilage, producing improved levels of function and preventing early osteoarthritis. The intermediate results have been promising in terms of functional and clinical improvement. Our aim was to explore the hypothesis that the histological quality of the repair tissue formed after autologous chondrocyte implantation improved with increasing time after implantation. In all, 248 patients who had undergone autologous chondrocyte implantation had biopsies taken of the repair tissue which then underwent histological grading. Statistical analysis suggested that with doubling of the time after implantation the likelihood of a favourable histological outcome was increased by more than fourfold (p < 0.001).

Abstract
The shape and appearance of the optic nerve head region are sensitive to changes associated with glaucoma and diabetes that may be otherwise asymptomatic. The changes can be diagnostic of the diseases, and tracking of the changes in sequential images can be used to assess treatment and the progress of the illness. At present, change detection and tracking are performed manually, which can be a cause of poor repeatability. We are concerned with developing automated techniques of generating quantitative descriptions of the retinal images that might be used in diagnosis and assessment. In this paper, we investigate the use of images that have been collected and stored remotely, as this will replicate capture and automated processing by outreach clinics. Normal and abnormal images were collected from a range of sources, to simulate the mass screening process. The images were processed using simple signal-processing methods and divided into two groups. Using a chi-squared test, the separation of normal and abnormal images using this test was found to be highly significant (p < 0.05, n = 60).

Abstract
The diagnosis of complete tears of the ulnar collateral ligament of the thumb metacarpophalangeal (MP) joint depends on demonstration of excessive laxity of the ligament, but there is controversy on whether laxity greater than a certain cut-off value or laxity greater than the opposite thumb is the criterion for diagnosis. We examined 200 thumbs of 100 normal individuals in extension and in 30 degrees of flexion. In 34% of subjects there was a difference of 10 degrees or more between right and left thumbs in extension, and 12% had a difference of at least 15 degrees. In flexion, 22% of thumbs differed by 10 degrees or more and 3% by 15 degrees or more. Comparison with the uninjured contralateral thumb is unreliable in many individuals. We recommend the lack of a definite end point on stress examination as indicating complete rupture of the ulnar collateral ligament.
