Abstract
BACKGROUND HIV pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV acquisition. To enable routine commissioning of PrEP in England, we aimed to establish population need, duration of need, PrEP uptake, and duration of use in attendees of sexual health services (SHS) in England. METHODS The Impact Trial was a prospective, open-label, single-arm, multicentre trial conducted at 157 SHS across England between Oct 13, 2017, and July 12, 2020. Clinicians assessed HIV-negative attendees for their risk of HIV acquisition to identify those who were eligible to participate and receive either daily or event-based oral PrEP (tenofovir disoproxil maleate with emtricitabine), as appropriate. Eligible participants were aged 16 years or older, considered HIV-negative on the day of enrolment, and willing to adhere to the trial procedures. Non-trial attendees are mutually exclusive of trial participants and included SHS attendees who were not recruited to the Impact Trial at any point. They include HIV-negative individuals aged 16 years or older who attended a participating SHS at least once after recruitment at that SHS had begun and before Feb 29, 2020. The main outcomes assessed were PrEP need, uptake, and use, and HIV and sexually transmitted infection (STI) incidence. Data are presented up to Feb 29, 2020, before the introduction of COVID-19 control measures. The study is registered with ClinicalTrials.gov, NCT03253757. FINDINGS In this analysis, we include 21 356 of 24 268 participants enrolled before Feb 29, 2020. 20 403 participants (95·5%) were men who have sex with men (MSM). Uptake of PrEP among SHS attendees clinically assessed and coded as eligible was 21 292 (57·1%) of 37 289. 18 400 trial participants had at least one post-enrolment visit and a median of 361 days of follow-up (IQR 143-638); 14 039 (75·9%) of these had enough PrEP prescribed to provide protection for 75% of their follow-up time. Among MSM, HIV incidence was 0·13 (95% CI 0·08-0·19) per 100 person-years in trial participants (27 seroconversions) and 0·95 (95% CI 0·88-1·03) per 100 person-years in non-trial attendees (587 seroconversions; proportionate reduction of 86·8%, 95% CI 80·2-91·6). 18 607 bacterial STIs were recorded (incidence 68·1 per 100 person-years in trial participants who were MSM). 4343 (24·4%) MSM participants were diagnosed with two or more STIs, accounting for 14 800 (79·5%) of all 18 607 diagnoses. INTERPRETATION PrEP need was higher than initially estimated by an expert stakeholder group. The high proportion of follow-up time protected by PrEP suggests that the need for protection persisted throughout trial participation for most participants. HIV incidence among MSM trial participants was low. The large unmet need for PrEP suggests that greater provision is required to maximise the potential of a national programme. The high incidence of bacterial STIs among participants, concentrated within a subgroup of PrEP users, presents an opportunity for tailored STI control measures. FUNDING NHS England.

Abstract
Getting to Zero is a commonly cited strategic aim to reduce mortality due to both HIV and avoidable deaths among people with HIV. However, no clear definitions are attached to these aims with regard to what constitutes HIV-related or preventable mortality, and their ambition is limited. This Position Paper presents consensus recommendations to define preventable HIV-related mortality for a pragmatic approach to public health monitoring by use of national HIV surveillance data. These recommendations were informed by a comprehensive literature review and agreed by 42 international experts, including clinicians, public health professionals, researchers, commissioners, and community representatives. By applying the recommendations to 2019 national HIV surveillance data from the UK, we show that 30% of deaths among people with HIV were HIV-related or possibly HIV-related, and at least 63% of these deaths were preventable or potentially preventable. The application of these recommendations by health authorities will ensure consistent monitoring of HIV elimination targets and allow for the identification of inequalities and areas for intervention.

Abstract
Background:The Phase 3b/4 study ORAL Shift demonstrated sustained efficacy and safety of tofacitinib modified-release (MR) 11 mg once daily (QD) following methotrexate (MTX) withdrawal that was non-inferior to continued tofacitinib + MTX use (per DAS28-4[ESR]), in patients (pts) with rheumatoid arthritis (RA) who achieved CDAI-defined low disease activity (LDA) with tofacitinib + MTX at Week (W)24.1Objectives:To assess the performance of alternative disease activity measures at W24 (randomisation) and W48 (study endpoint) in ORAL Shift.Methods:ORAL Shift (NCT02831855) enrolled pts aged ≥18 years with moderate to severe RA and an inadequate response to MTX. Pts received open-label tofacitinib MR 11 mg QD + MTX for 24 weeks. Achievement of CDAI LDA (≤10) at W24 was set as the criteria for entry to the 24-week double-blind MTX withdrawal phase, with pts randomised 1:1 to receive tofacitinib MR 11 mg QD + placebo (PBO) (ie blinded MTX withdrawal) or continue tofacitinib + MTX. In this post hoc analysis, efficacy analyses were performed in 8 subgroups defined by achievement of various disease activity criteria at W24: DAS28-4(ESR) remission (<2.6) or LDA (≤3.2); DAS28-4(CRP) <2.6 or ≤3.2; RAPID3 remission (≤3) or LDA (≤6); CDAI remission (≤2.8); and SDAI remission (≤3.3). For each subgroup, the proportion of pts who achieved the corresponding disease activity criterion at W48 was calculated, with a 95% confidence interval (CI) estimated using the normal approximation to the binomial distribution. The change (Δ) from W24 to W48 in least squares (LS) mean DAS28-4(ESR) and DAS28-4(CRP) was also calculated in each subgroup, with a 95% CI for the difference between treatment groups estimated using a mixed model with repeated measures. Nominal p values were calculated and are presented with no formal statistical hypothesis testing formulated.Results:Overall, 694 pts entered the open-label phase of ORAL Shift, and 530 were randomised and received treatment in the double-blind phase; 264 and 266 pts received tofacitinib + PBO and tofacitinib + MTX, respectively (Figure 1a). Considering those pts who were randomised and treated, the proportion of pts achieving each disease activity criterion at W24 varied, but was similar between treatments within each subgroup (Figure 1a). Among pts who met each disease activity criterion at W24, generally the majority of pts in both treatment groups also met the same criterion at W48 (Figure 1b). Numerically more pts receiving tofacitinib + MTX vs tofacitinib + PBO continued to meet the corresponding criterion at W48. Regardless of the disease activity criterion met at W24, differences between treatment groups in LS mean ΔDAS28-4(ESR) (Figure 1c) and ΔDAS28-4(CRP) (data not shown) from W24 to W48 favoured tofacitinib + MTX vs tofacitinib + PBO.Conclusion:This post hoc analysis of data from pts randomised and treated in ORAL Shift demonstrated that, regardless of the disease activity state criterion met at W24, generally a majority of pts receiving tofacitinib maintained achievement of the corresponding disease activity criterion at W48, with or without continued MTX. Differences between treatment groups in LS mean ΔDAS28-4(ESR) from W24 to W48, as defined by achievement of LDA or remission with a variety of disease activity measures, were less than a change of 1.2, which is considered to be the threshold for a minimal clinically important improvement.2References:[1]Cohen et al.

Abstract
Background:Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). A recent ad hoc safety analysis (as of August 2019; may be subject to change) from an ongoing, open-label, randomised, post-authorisation safety study, Study A3921133 (NCT02092467), conducted in RA patients (pts) aged ≥50 years with ≥1 cardiovascular risk factor has shown that incidence rates (IRs) of serious infection events (SIEs) were higher with tofacitinib 10 mg BID vs tumour necrosis factor inhibitors (TNFi; adalimumab [ADA] and etanercept) and this difference was more pronounced in pts aged ≥65 years (Pfizer Inc; data on file).Objectives:To assess the IRs of overall infection events and SIEs in pts from Phase (P)2, P3 and P3b/4 tofacitinib RA trials which had a TNFi (ADA) active control or comparator arm.Methods:This is a post hoc analysis of Month 0–12 data pooled from P2 (A3921035;NCT00550446[first 12-week randomised parallel treatment period only]), P3 (ORAL Standard;NCT00853385) and P3b/4 (ORAL Strategy;NCT02187055) studies. Pts randomised to receive tofacitinib 5 mg BID, tofacitinib 10 mg BID, ADA 40 mg subcutaneously every other week and placebo (PBO) were included and assessed overall and by age (<65 or ≥65 years). SIEs were defined as infections requiring hospitalisation or parenteral antimicrobial therapy, or meeting other criteria for a serious adverse event. IRs (pts with events/100 pt-years of exposure [PY]) and 95% confidence intervals (CIs) were calculated for all infection events and SIEs; only the first infection events that occurred up to 28 days after the last dose or to the data cut-off date were considered.Results:Of 2180 pts included in the pooled studies (tofacitinib 5 mg BID: N=1064 [943.4 PY]; tofacitinib 10 mg BID: N=306 [236.6 PY]; ADA: N=643 [554.3 PY]; PBO: N=167 [108.1 PY]), 1841 (84.4%) were aged <65 years and 339 (15.6%) were aged ≥65 years. In general, the IRs for all infection events and SIEs were higher with tofacitinib 5 mg BID, tofacitinib 10 mg BID and ADA in pts aged ≥65 years compared with pts aged <65 years. Overall and when stratified by age, IRs for all infection events were similar across the active treatment groups (Figure 1); IRs with PBO were lower vs the active treatment groups overall and in pts aged <65 years, and numerically lower vs the active treatment groups in pts aged ≥65 years. IRs for SIEs were comparable across active treatment groups in pts aged <65 years, while among pts aged ≥65 years, IRs were numerically higher for tofacitinib 10 mg BID vs ADA, and appeared to be similar for tofacitinib 5 mg BID and ADA (Figure 2).Conclusion:In this analysis of data pooled from P2, P3 and P3b/4 tofacitinib RA studies which included a TNFi arm (ADA), the risk of SIEs or infections overall was similar for tofacitinib and ADA with the exception of a numerically higher rate of SIEs with tofacitinib 10 mg BID vs ADA in pts aged ≥65 years. In most countries, tofacitinib 10 mg BID is not an approved dose for the treatment of RA. This post hoc comparison is limited by variation in sample size and PY of exposure between treatment and age groups, and a small number of cases of SIEs in the ≥65-year age group resulting in wide 95% CIs; interpretation of results should be made with caution. The findings in the present analysis are consistent with increasing age being a known risk factor for infections.Acknowledgments:Study sponsored by Pfizer Inc.

Abstract
Abstract
Relationship-centered dementia care (RCDC) has been related to improved quality of residential long-term care for persons living with dementia (PLWD). The senses framework supports accomplishing RCDC, whereby PLWD meet fundamental needs or senses through caregiving relationships. This study explored the application of the senses framework to a non-residential, long-term care setting, and included relationships across formal and informal caregivers. The study design is a qualitative, descriptive study of PLWD (N=3), with matched formal (N=3) and informal (N=3) caregivers in one adult day care setting in North Carolina. Semi-structured individual interviews explored each of the six senses of security, belonging, continuity, purpose, achievement, and significance. Interviews were analyzed using both inductive and deductive thematic analysis. Themes elucidate convergence and divergence of how senses are met or not met across triads of caregiving relationships. Findings inform our understanding of how to integrate the larger social network of PLWD for relationship-centered care.

Abstract
Abstract
Objective
The Clock Drawing Test (CDT) is a screening instrument for cognitive impairment known for its quick and easy administration style. Studies have examined if different qualitative errors on the CDT discriminate cognitive impairment from normal aging. Moreover, current research has investigated qualitative errors on the CDT in various populations (i.e. Brazil, Japan, Korea). To the best of the authors’ knowledge however, there has been no previous research on qualitative errors seen on the CDT within Russian-speaking populations. To address this gap, the present study examined qualitative errors committed on the CDT by native Russian-speakers compared to English-speaking counterparts.
Method
Data was retrospectively collected from a sample comprised of 13 Russian-speaking immigrants and 29 English-speakers. All participants were seen for neuropsychological testing at an outpatient clinic in eastern Massachusetts and diagnosed with major neurocognitive disorder.
Results
Contingency analysis revealed no significant differences in qualitative errors when comparing Russian-speakers with major neurocognitive disorder to English-speakers diagnosed with the same.
Conclusions
Due to similar frequencies of qualitative errors between these groups, these results suggest that the CDT may have broad utility for assessing gross cognitive functioning regardless of a patient’s native language or cultural background.

Abstract
Abstract
Objective
The Clock Drawing Test (CDT) is among the most researched measures of cognitive functioning and is frequently used by clinicians as a screening instrument for cognitive impairment. Nearly all the existing research on the CDT involves groups of patients diagnosed with a mild cognitive impairment (MCI) or dementia; however, recent updates to the diagnostic system (i.e., DSM-5) saw the creation of the mild and major neurocognitive disorders (NCD), designed to replace MCI and dementia diagnoses. These new diagnoses are similar to their predecessors, however, distinct differences exist that drastically alter the characteristics of these groups. Therefore, this study aimed to examine if qualitative errors on the CDT as described by Rouleau et al. (1992) are consistent with a diagnosis of mild or major NCD according to DSM-5.
Method
Data was retrospectively collected from a sample of patients seen at an outpatient clinic in eastern Massachusetts. CDTs from 14 healthy controls, 31 patients with mild NCD, and 18 patients with major NCD were made available for analysis.
Results
Contingency analysis revealed no significant differences in error frequencies when comparing mild NCD to healthy controls. Patients with major NCD committed significantly higher rates of specific stimulus bound (p = 0.021), conceptual (p = 0.026), and spatial/planning (p = 0.037) errors compared to others in the sample.
Conclusions
While CDT errors do not appear to distinguish mild NCD from healthy controls in our sample, our findings suggest that certain errors may serve as a warning sign to incipient major NCDs. Clinical implications and future directions are discussed.

Abstract
Introduction: Youths with visual impairments (i.e., blindness or low vision) experience difficulties with forming and maintaining social relationships with peers. These difficulties challenge their psychosocial functioning and put them at risk of being lonelier later in life. The study’s primary goal was to investigate how intra- and interpersonal factors during adolescence influence Loneliness in young adulthood. Methods: Analyses were conducted on data from a national data set. Participants ( N = 96) were interviewed at two different time points. General linear regression and mediation analyses were used to examine the role of social competence, personality, and satisfaction with social support, measured at mean age 17.83, and on Loneliness measured at mean age 23.45. Results: Analyses showed that adolescents with visual impairments who were more emotionally stable and had higher social competence during adolescence were less lonely later in life. In addition, the results showed that emotionally unstable adolescents reported lower social competence and, therefore, were lonelier in young adulthood. Discussion: These findings indicate that factors connected to Loneliness in young adulthood include people’s personality traits and their level of social competence at a younger age. Implications for practitioners: Knowing the underlying causes of an individual’s Loneliness assists practitioners in selecting what type of intervention would be suitable for addressing these issues. Those with low social skills benefit more from social skills training and those with negative biases of their own functioning profit more from interventions based on cognitive approaches. Screening methods could be used in order to determine these underlying issues and personality structure, before assigning persons to specific interventions.

Abstract
This article describes the results in the employment domain of a larger study of the lifestyles of 328 Canadian youths, aged 15–21 and 22–30, 131 of whom were blind and 197 of whom had low vision. The youths completed a survey on their work-related experiences, including their current employment status and job-search strategies. In addition to characterizing the overall employment-related experiences of the youths, the study explored differences by visual status, gender, and age group.

Abstract
This article presents a systematic review of the research evidence on the effects of the characteristics of typefaces on the legibility of text for adult readers with low vision. The review revealed that research has not produced consistent findings and thus that there is a need to develop standards and guidelines that are informed by evidence.

Abstract
This survey of the social and leisure experiences of Canadian youths with visual impairments found that, in general, youths with low vision experienced more social challenges than did their peers who were blind. Levels of social support were not found to differ on the basis of level of vision, sex, or age.

Abstract
BACKGROUND Patient selection for critical care admission must balance patient safety with optimal resource allocation. This study aimed to determine the relationship between critical care admission, and postoperative mortality after abdominal surgery. METHODS This prespecified secondary analysis of a multicentre, prospective, observational study included consecutive patients enrolled in the DISCOVER study from UK and Republic of Ireland undergoing major gastrointestinal and liver surgery between October and December 2014. The primary outcome was 30-day mortality. Multivariate logistic regression was used to explore associations between critical care admission (planned and unplanned) and mortality, and inter-centre variation in critical care admission after emergency laparotomy. RESULTS Of 4529 patients included, 37.8% (n=1713) underwent planned critical care admissions from theatre. Some 3.1% (n=86/2816) admitted to ward-level care subsequently underwent unplanned critical care admission. Overall 30-day mortality was 2.9% (n=133/4519), and the risk-adjusted association between 30-day mortality and critical care admission was higher in unplanned [odds ratio (OR): 8.65, 95% confidence interval (CI): 3.51-19.97) than planned admissions (OR: 2.32, 95% CI: 1.43-3.85). Some 26.7% of patients (n=1210/4529) underwent emergency laparotomies. After adjustment, 49.3% (95% CI: 46.8-51.9%, P<0.001) were predicted to have planned critical care admissions, with 7% (n=10/145) of centres outside the 95% CI. CONCLUSIONS After risk adjustment, no 30-day survival benefit was identified for either planned or unplanned postoperative admissions to critical care within this cohort. This likely represents appropriate admission of the highest-risk patients. Planned admissions in selected, intermediate-risk patients may present a strategy to mitigate the risk of unplanned admission. Substantial inter-centre variation exists in planned critical care admissions after emergency laparotomies.

Abstract
Fully integrated monolithic, multi-channel InP-based coherent receiver PICs and transceiver modules with extended C-band tunability are described. These PICs operate at 33 and 44 Gbaud per channel under dual polarization (DP) 16-QAM modulation. Fourteen-channel monolithic InP receiver PICs show integration and data rate scaling capability to operate at 44 Gbaud under DP 16-QAM modulation for combined 4.9 Tb/s total capacity. Six channel simultaneous operation of a commercial transceiver module at 33 Gbaud is demonstrated for a variety of modulation formats including DP 16-QAM for >1.2Tbit/s aggregate data capacity.

The Experience of a Randomized Clinical Trial of Closed-Circuit Television versus Eccentric Viewing Training for People with Age-Related Macular Degeneration.

Abstract
Introduction In addition to optical devices, closed-circuit televisions (CCTVs) and eccentric viewing training are both recognized interventions to improve reading performance in individuals with vision loss secondary to age-related macular degeneration. Both are relatively expensive, however, either in the cost of the device or in the amount of time personnel need to provide training. In this randomized trial, we compared the effectiveness of these two interventions. Methods Participants with age-related macular degeneration and visual acuity between 6/48 (20/160) and 6/120 (20/400) first received basic low vision care, including optical devices. At the subsequent baseline visit, they undertook a battery of measures including logMAR visual acuity; reading speed and accuracy for text in 1.3M and 1M fonts; reading information on medicine bottles, utility bills, and food packages; the NEI-VFQ; the Geriatric Depression Scale; and a reading inventory questionnaire. They were then randomized to either obtaining a CCTV for home use or eccentric viewing training over the following six weeks. Results Recruitment was more difficult than expected for this population. Of 145 patients referred, 29 met the inclusion-exclusion criteria, 14 were willing to enroll, and 10 completed the trial. For the primary outcome (reading speed for 1.3M print), there was a significant improvement between baseline and outcome for the CCTV group (p = 0.005), but not for the eccentric viewing training group (p = 0.28), and the CCTV group showed significantly greater change (p = 0.04). There was a nonsignificant improvement in reading speed for 1M text and a decrease in the amount of time taken to read utility bill information in the CCTV group. There was a significant improvement in near visual acuity with current glasses with eccentric viewing training. The other measures did not reach statistical significance. Discussion Randomized clinical trials for low vision rehabilitation, particularly in the elderly population with vision loss, are challenging, but such trials are important for the allocation of resources. This trial showed early indications of more impact on reading performance from CCTV than eccentric viewing training.

Abstract
Coccidioidomycosis is associated with soil-disruptive work in Coccidioides-endemic areas of the southwestern United States. Among 3,572 workers constructing 2 solar power-generating facilities in San Luis Obispo County, California, USA, we identified 44 patients with symptom onset during October 2011-April 2014 (attack rate 1.2 cases/100 workers). Of these 44 patients, 20 resided in California outside San Luis Obispo County and 10 resided in another state; 9 were hospitalized (median 3 days), 34 missed work (median 22 days), and 2 had disseminated disease. Of the 25 patients who frequently performed soil-disruptive work, 6 reported frequent use of respiratory protection. As solar farm construction in Coccidioides-endemic areas increases, additional workers will probably be exposed and infected unless awareness is emphasized and effective exposure reduction measures implemented, including limiting dust generation and providing respiratory protection. Medical providers, including those in non-Coccidioides-endemic areas, should suspect coccidioidomycosis in workers with compatible illness and report cases to their local health department.

Abstract
OBJECTIVES Most current prescription labels fail to meet print guidelines, especially in print size. We therefore compared the legibility of current prescription medication labels against the legibility of prototype labels, based on current guidelines for legibility. METHOD Sample medication labels were obtained from pharmacies, and prototype medication labels were developed according to legibility guidelines from nongovernmental organizations and pharmacy organizations. Three groups of participants, consisting of older adults with normal vision, older adults with visual impairment and younger adults with visual impairment (total N = 71) took part. Participants were asked to read and rank the labels. Reading speed and accuracy were determined. RESULTS Accuracies were high (75%-100%), and there were no significant differences between samples or prototypes or between groups. Prototypes, however, were read faster than samples (p < 0.001). Subjectively, participants preferred the largest print option (p < 0.001) and instructions with the numbers written in highlighted uppercase words (p < 0.001). DISCUSSION The results indicate that improvements to the label would include larger print size, a consistent layout with left justification and using upper case with highlighting for emphasis of the numbers in the instructions.

Abstract
INTRODUCTION The legibility of medication labelling is a concern for all Canadians, because poor or illegible labelling may lead to miscommunication of medication information and poor patient outcomes. There are currently few guidelines and no regulations regarding print standards on medication labels. This study analyzed sample prescription labels from Ontario, Canada, and compared them with print legibility guidelines (both generic and specific to medication labels). METHODS Cluster sampling was used to randomly select a total of 45 pharmacies in the tri-cities of Kitchener, Waterloo and Cambridge. Pharmacies were asked to supply a regular label with a hypothetical prescription. The print characteristics of patient-critical information were compared against the recommendations for prescription labels by pharmaceutical and health organizations and for print accessibility by nongovernmental organizations. RESULTS More than 90% of labels followed the guidelines for font style, contrast, print colour and nonglossy paper. However, only 44% of the medication instructions met the minimum guideline of 12-point print size, and none of the drug or patient names met this standard. Only 5% of the labels were judged to make the best use of space, and 51% used left alignment. None of the instructions were in sentence case, as is recommended. DISCUSSION We found discrepancies between guidelines and current labels in print size, justification, spacing and methods of emphasis. CONCLUSION Improvements in pharmacy labelling are possible without moving to new technologies or changing the size of labels and would be expected to enhance patient outcomes.

Abstract
OBJECTIVE To develop a psychometric tool to assess preparedness for employment for persons who are blind or visually impaired. PARTICIPANTS Two hundred and thirty nine working aged adults who are blind or visually impaired. METHODS The content for this tool was generated through a literature review and through focus groups with successfully employed persons with vision impairments as well as hiring managers and rehabilitation workers of same. Content of the instrument was enhanced through a survey of persons with vision loss, using the draft instrument and through factor analyses of their responses. RESULTS Factor analyses of participants' responses resulted in 12 scales each of which assessed a different factor related to employment. Scales had good to excellent reliability with the exception of one scale that had acceptable reliability (as measured by Cronbach's Alpha). CONCLUSION The CNIB TAPE appears to be an effective instrument for assessing preparedness for employment.

Abstract
4613 Background: Invasive pancreatic carcinoma is a virtually lethal disease, mostly because of the failure to detect it at a sufficiently early timepoint for successful treatment. Our laboratory has identified a unique biomarker detected by MAb PAM4 that shows high specificity for a mucin glycoprotein expressed by pancreatic carcinoma (PC). While identified in almost 90% of PC and its precursor lesions, the antigen is not detectable in normal pancreas. We are investigating this biomarker for the early detection of PC. Methods: Both immunohistochemical (IHC) and enzyme immunoassay (EIA) were employed for detection and/or quantitation of PAM4-mucin in tissue and sera, respectively. Results: We have extended our prior IHC results with precursor lesions (Clin Cancer Res 2007;13:7380–7); PAM4 gave an intense, diffuse labeling pattern in 81% of mucinous cystic neoplasms (MCN), with an additional 11% showing a focal pattern (n=27). Thus, a total of 92% of MCN showed evidence of PAM4-antigen expression. Of interest, a difference in the labeling pattern was observed in association with the grade of dysplasia, providing easy identification of MCN with high- grade dysplasia. We previously reported use of an EIA for quantitation of PAM4-antigen in sera. The assay demonstrated a sensitivity and specificity of 77% and 95%, respectively, for identification of PC (J Clin Oncol, 2006;24:252–8). We have now confirmed these results in a set of serum specimens (n= 49 PC, 13 normal) for which staging information was available. Overall specificity and sensitivity were 82% and 85%, respectively, calculated by ROC curve analysis (AUC=0.878±0.045; 95% CI=0.769–0.947). Although only a small number of specimens were from patients with stage I disease (n=12), 92% of these were above the cutoff value for positive response. A correlation was observed for average concentration of antigen in the circulation with stage of disease (R2=0.988). Conclusions: IHC and EIA results indicate that PAM4 identifies a biomarker for PC that is present at the earliest stages of neoplastic transformation, thus warranting controlled analyses of larger specimen numbers.

Abstract
4564 Background: The initial diagnosis of pancreatic cancer is difficult at best. We developed MAb-PAM4 reactive with a unique epitope within MUC1 that is expressed in most pancreatic cancers, but not in normal or inflammatory pancreas, nor most other normal and neoplastic tissues. Our current focus is the development of a pretargeting procedure that can greatly enhance targeting sensitivity while retaining the MAb’s high specificity. Methods: TF10 is a novel humanized recombinant bsMAb with divalent binding to PAM4-defined MUC1 and monovalent binding to histamine-succinyl-glycine (HSG). TF10 is a 157 kDa protein having >85% binding to MUC1 and >90% with HSG. Athymic nude mice bearing CaPan1, human pancreatic cancer, were injected with 125I-TF10 to assess biodistribution. Other animals were given varying doses of TF10 followed 16 h later with 111In-IMP-288, a divalent-HSG-peptide. These animals were imaged 3 h after the 111In-IMP-288-injection and then necropsied. Results: 125I-labeled TF10 cleared rapidly from the blood, with blood levels <0.25 ± 0.02 %ID/g at 16 h, and no accumulation in any normal tissues. Tumor uptake was 7.16 ± 1.10, 3.47 ± 0.66, and 1.65 ± 0.57 % ID/g at 6, 16, and 48 hrs, respectively. These data confirmed that for a pretargeted imaging study a 16-h interval is sufficient to clear the blood so that 111In-IMP-288 could be administered. At 3 h, the imaging studies showed intense uptake of radiolabeled peptide within the tumors (avg. 0.5 cm3 - 0.3 g at necropsy) with no evidence of uptake in any normal tissues, while no targeting was seen in animals given the 111In-IMP-288 alone. At necropsy, tumor uptake of the 111In-IMP-288 in the TF10 pretargeted animals was 24.3 ± 1.7 % ID/g, while for 111In-IMP-288 alone tumor uptake was only 0.012 ± 0.002 % ID/g. Tumor/blood, liver, lungs, and kidney ratios averaged 2800:1, 139:1, 184:1, and 14.2:1, respectively, in the pretargeted animals. Conclusions: These results demonstrate that this novel PAM4-based pretargeting agent targets and images xenografted human pancreatic cancer with high signal-to-background ratios. In addition to imaging, TF10 may prove useful for pretargeted therapy of pancreas cancer. (Supported in part by grant CA115755 from the NIH.) No significant financial relationships to disclose.

Abstract
The chimeric fusion protein AML1-ETO, created by the t(8;21) translocation, recruits histone deacetylase (HDAC) to AML1-dependent promoters, resulting in transcriptional repression of the target genes. We analyzed the transcriptional changes in t(8;21) Kasumi-1 AML cells in response to the HDAC inhibitors, depsipeptide (FK228) and suberoylanilide hydroxamic acid (SAHA), which induced marked growth inhibition and apoptosis. Using cDNA array, annexin A1 (ANXA1) was identified as one of the FK228-induced genes. Induction of ANXA1 mRNA was associated with histone acetylation in ANXA1 promoter and reversal of the HDAC-dependent suppression of C/EBPalpha by AML1-ETO with direct recruitment of C/EBPalpha to ANXA1 promoter. This led to increase in the N-terminal cleaved isoform of ANXA1 protein and accumulation of ANXA1 on cell membrane. Neutralization with anti-ANXA1 antibody or gene silencing with ANXA1 siRNA inhibited FK228-induced apoptosis, suggesting that the upregulation of endogenous ANXA1 promotes cell death. FK228-induced ANXA1 expression was associated with massive increase in cell attachment and engulfment of Kasumi-1 cells by human THP-1-derived macrophages, which was completely abrogated with ANXA1 knockdown via siRNA transfection or ANXA1 neutralization. These findings identify a novel mechanism of action of HDAC inhibitors, which induce the expression and externalization of ANXA1 in leukemic cells, which in turn mediates the phagocytic clearance of apoptotic cells by macrophages.

Abstract
BACKGROUND A review of the literature and current practice patterns for vision rehabilitation care in Canada provide a basis for this pilot study, which was undertaken to explore related issues from the perspectives of older adults and low vision service providers. The pilot study was overseen by a number of collaborators whose names are listed at the end of this paper. METHODS Thirty people aged 60 years or older who had vision impairments and were clients of the Canadian National Institute for the Blind were surveyed by telephone. Ophthalmologists, optometrists, and opticians completed a mail questionnaire. Vision rehabilitation practitioners and nurses, ophthalmic technicians, and service providers for low vision technical aids were surveyed by e-mail. RESULTS Ophthalmologists are a primary source of referrals to low vision services, but low functional vision does not always trigger such referrals, nor are referrals always timely. Optometrists are primary providers of low vision services, including dispensing of low vision aids, but such aids are expensive, and inadequate training in their use may contribute to noncompliance. Costs associated with providing low vision assessments and services are higher than compensation to vision service providers, whose capacity to meet increasing demand is limited. In addition, there are disparities between rural and urban areas and among provinces in the availability of, and funding for, services and aids. INTERPRETATION On the basis of the findings, an emergent theory is proposed on the consequences resulting from lack of planning and standards for vision rehabilitation care. The implications of this study form the basis for further research.

Abstract
Two cases are described of patients who presented with a buttock abscess 3 and 5 years after restorative proctocolectomy for ulcerative colitis. In both the abscess was secondary to a fistula, which was shown on further investigation to be a track traversing the greater sciatic notch. Both patients had had an ileo-anal J-pouch after a proctectomy which had included a mesorectal excision. The possibility that these unusual fistulae might be more common following removal of the mesorectum rather than a close rectal dissection is explored.

Abstract
Jasmonates are a group of small lipids produced in plants, which function as plant stress hormones. We have previously shown that jasmonates can exert significant cytotoxic effects upon human cancer cells. The purpose of the present study was to determine the effects of jasmonates on parasites. To that end, we chose 2 major human blood parasites, Plasmodium falciparum, a unicellular parasite, and Schistosoma mansoni, a multicellular helminth parasite, and studied the effects of jasmonates on these parasites in vitro. We found that jasmonates are cytotoxic toward both parasites, with P. falciparum being the more susceptible. Jasmonates did not cause any damage to control human erythrocytes at the maximum concentration used in the experiments. This is the first study demonstrating the antiparasitic potential of plant-derived jasmonates.

Abstract
In mammalian cells, ceramide mediates death by chemotherapeutic drugs. We analysed, for the first time, the role of ceramide in inhibiting growth of the malaria-causing parasite Plasmodium falciparum. Added exogenously, ceramide significantly decreased the number of parasites, and this effect was abolished by sphingosine-1-phosphate, a biological antagonist of ceramide action. Ceramide can induce death of cancer cells by decreasing glutathione levels, and in our work it induced dose- and time-dependent depletion of glutathione in P. falciparum parasites. N-acetylcysteine, a precursor of glutathione, abrogated the cytotoxic effect of ceramide. Thus, ceramide can mediate growth inhibition of P. falciparum parasites by decreasing glutathione levels. The antimalarial drugs artemisinin and mefloquine induced the death of P. falciparum parasites by sphingomyelinase-generated ceramide and by decreasing parasite glutathione levels. Altogether, ceramide was identified as a signalling molecule capable of inducing growth inhibition of P. falciparum malarial parasites.

Abstract
A large variety of human pathogens are excreted in wastewater including bacteria, viruses, protozoan cysts and helminth eggs. In raw sewage, human pathogens reach high numbers, thereafter decreasing successively at each treatment step. However, the final effluents still contain a large fraction of these pathogens that may pose a serious public health. Among the various crops irrigated with effluents, vegetables are the most vulnerable to contamination. Vegetables, usually eaten raw (uncooked) or with rich dressings (causing regrowth of some pathogenic bacteria) pose the main threat to humans. The importance of microbiological and parasitological criteria for reused water has been repeatedly emphasized. Some microbiological recommendations based on epidemiological data have been established for untreated wastewater, there is still a need to define the criteria for effluent quality required for unrestricted crop irrigation. This paper presents a field study comparison of two irrigation methods: surface and subsurface of field crops (mainly vineyard) and follow-up of Cryptosporidium oocysts in soil at different depths (0 to 90 cm). Oocysts were isolated at all depths without a clear pattern of distribution (0 to 640 oocysts/g). In addition different vegetables irrigated with different effluent qualities were tested for the presence of Cryptosporidium oocysts and Giardia cysts. The highest prevalence of oocysts was found on zucchini that has a sticky and hairy outer surface (80 to 10,000 oocysts/0.5 kg).

Abstract
The present work deals with optimization of excystation of Cryptosporidium parvum oocysts and the infection process of tissue culture cells by the parasite. It was shown that presence of the bile salt sodium taurocholate in the incubation medium expedited excystation of the tested GCH1 isolate and enhanced it, as compared with bleaching of the oocysts. This bile salt had no effect on the viability of tissue culture cell lines MDBK and HCT-8 at the tested concentration of 0.375% for up to 2 hr of coincubation. Infection studies conducted on tissue culture cells showed higher infection rates in the presence of sodium taurocholate than with bleached oocysts in the absence of this bile salt. It may be concluded that, at least as regards the GCH1 strain of C. parvum, the whole infection process can be performed in the presence of sodium taurocholate, and does not require separation and cleaning of the excysted sporozoites before their application to tissue culture cells.
