Abstract
BACKGROUND This study aimed to evaluate the efficacy and safety of intrathecal pemetrexed (IP) for treating patients with leptomeningeal metastases (LM) from non-small-cell lung cancer (NSCLC) who progressed from epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) treatment in an expanded, prospective, single-arm, phase II clinical study (ChiCTR1800016615). PATIENTS AND METHODS Patients with confirmed NSCLC-LM who progressed from TKI received IP (50 mg, day 1/day 5 for 1 week, then every 3 weeks for four cycles, and then once monthly) until disease progression or intolerance. Objectives were to assess overall survival (OS), response rate, and safety. Measurable lesions were assessed by investigator according to RECIST version 1.1. LM were assessed according to the Response Assessment in Neuro-Oncology (RANO) criteria. RESULTS The study included 132 patients; 68% were female and median age was 52 years (31-74 years). The median OS was 12 months (95% confidence interval 10.4-13.6 months), RANO-assessed response rate was 80.3% (106/132), and the most common adverse event was myelosuppression (n = 42; 31.8%), which reversed after symptomatic treatment. The results of subgroup analysis showed that absence of brain parenchymal metastasis, good Eastern Cooperative Oncology Group score, good response to IP treatment, negative cytology after treatment, and patients without neck/back pain/difficult defecation had longer survival. Gender, age, previous intrathecal methotrexate/cytarabine, and whole-brain radiotherapy had no significant influence on OS. CONCLUSIONS This study further showed that IP is an effective and safe treatment method for the EGFR-TKI-failed NSCLC-LM, and should be recommended for these patients in clinical practice and guidelines.

Abstract
Food with a halal logo should turn out as an advantage to premises that have proactively
adapted to halal business ideas. As Islam teaches its followers on what food is good (halal)
and bad (haram) for consumption, the attachment of Islamic decency and goodness to
foodservice is expected to spur food premise Halal patronage. The objective of this paper
was to investigate the role of religiosity as a mediator in the relationship between
perceived behavioural control and intention on patronising at food premise with halal
logo. Survey data were collected from supermarket shoppers in all four states in Malaysia
such as Selangor, Johor, Kelantan and Pulau Pinang and analysed using partial leastsquares structural equations modelling (PLS-SEM) technique. The key findings were
religiosity as an important part in an indirect positive relationship between perceived
behavioural control and intention on patronising at food premise with halal logo, thus
giving support to the mediating effect of religiosity. An explanation for this mediating
effect was probably due to the high degree of dependency on religiosity among Muslim
consumers.

Abstract
BackgroundClinical manifestations of gut problems except for inflammatory bowel disease (IBD) have not been well-established in patients with ankylosing spondylitis (AS). One study investigated that 30% patients with axial spondyloarthritis (axSpA) had irritable bowel syndrome (IBS) symptoms meeting Rome III criteria.[1]ObjectivesTo determine the frequency of symptoms meeting Rome IV functional bowel disorder (FBD) in patients with AS, investigate factors associated with FBD symptoms, and assess whether having FBD symptoms might influence AS disease activity.MethodsIn this cross-sectional study, we consecutively enrolled 153 AS patients without known colonic ulcer and 56 sex- and age-matched controls to evaluate FBD (or its subtypes) symptoms.[2] In AS group, logistic regression models were used to explore whether demographic data, disease activity, level of gut inflammation, drug use, and fibromyalgia [3] were associated with presence of gut symptoms. Finally, potential impacts of gut symptoms on AS disease status were assessed in linear regression models.ResultsSixty (39.2%) of 153 AS patients had FBD symptoms, which was more prevalent than controls (23.2%). Besides, symptoms compatible with IBS and chronic diarrhea were detected in 18 and 43 AS patients respectively. For AS group, multivariable logistic regression analyses showed that symptoms of FBD, IBS, and chronic diarrhea were negatively associated with using non-steroidal anti-inflammatory drug (NSAID), and positively associated with comorbid fibromyalgia, respectively. In exploration about effects of FBD (or its subtypes) symptoms on AS disease activity by multivariable linear regression analyses, FBD symptoms and chronic diarrhea had positive associations with assessments of AS respectively.ConclusionPatients with AS had frequent symptoms compatible with FBD, IBS, and chronic diarrhea, proportions of which were lower in those with NSAID-use. The improvement of FBD symptoms, especially chronic diarrhea, might be conducive to disease status of AS patients.References[1]Wallman JK, et al. Ann Rheum Dis. 2020;79:159-61.[2]Mearin F, et al.

Background
Pulmonary vein (PV) isolation is the cornerstone of atrial fibrillation (AF) management. However, AF recurrence is extremely common after a single procedure. The CLOSE protocol, which is the standardisation of radiofrequency catheter ablation by delivering a point-by-point lesion set defined by ablation index (AI), has demonstrated 80% freedom of AF. Yet PV reconnection is still up to 38% in these patients (1). A small decrease in generator impedance (GI), which is not part of the AI algorithm, has been associated with recovery of PV conduction.
Purpose
The study aimed to identify whether lesions having a poor impedance drop (PID) after wide area circumferential ablation (WACA) are associated with PV reconnection, despite adopting to the CLOSE protocol.
Methods
120 consecutive patients who had both the index (i-AFA) and redo AF ablations (r-AFA) due to AF recurrence at our centre from Jan 2018 to Jun 2021 were screened. 18 patients who had WACA around PVs using high power (40 to 50W) with a minimum AI of 400, whilst adhering the CLOSE protocol during the i-AFA, and who had evidence of PV reconnection during r-AFA, were included in the study. Ones who had left atrial (LA) substrate or cryoablation were excluded. GI was measured between the skin patch and ablation catheter. CARTO® system was used to create LA electroanatomical maps (EAMs) and register ablation lesions.
Each WACA around PVs was divided into eight anatomical segments (Figure). PID was defined as an impedance change of <8Ω, based on previous studies (2). These lesions were identified and categorised to the relevant anatomical segment in the i-AFA. Locations of the discrete ablation lesions that re-isolated PVs during the r-AFA, were used as a surrogate to denote areas of PV reconnection. These were also spatially matched to the relevant anatomical segment. Each EAM was reviewed by two electrophysiologists.
Results
30 out of the 36 WACAs (83%) and on average, at least 2 segments per WACA (2.6; 95% confidence interval (CI): 2.2-3.1) had reconnected. 54% of the reconnected segments had at least one lesion with PID. Having a lesion with PID in a PV segment in the i-AFA was significantly associated with evidence of PV reconnection in the same segment in the r-AFA (odds ratio: 2.1 [95% CI: 1.3-3.6; p<0.01]). Right posterior/inferior (56%) and left anterior/superior (50%) PV segments were the most common areas to reconnect and these areas were also associated with a higher incidence of PID lesions in the i-AFA (94% and 67%, respectively). Conversely, 80% of segments with all lesions having an impedance drop of ≥8Ω had no PV reconnection.
Conclusion
Lesions with PID in the i-AFA could impact PV reconnection, despite lesion contiguity and an adequate AI. Identifying and targeting these areas of PID, in addition to the CLOSE protocol, could potentially reduce AF recurrence. Prospective studies are needed to validate this hypothesis and its safety.

Introduction
Chronic right ventricular apical pacing can lead to pacing induced cardiomyopathy in a significant proportion of patients. Conduction system pacing may restore more physiological activation of the heart, and has recently been shown to have favourable outcomes in clinical trials. However there remains concern regarding the long-term outcomes due to lead displacement and high pacing thresholds. The most widely used technique in current practice is to pace the His bundle proximal to the tricuspid valve. Distal His bundle pacing has a number of advantages over proximal His pacing, including, lower capture thresholds, a more stable lead position, less far field atrial sensing and better spacing from the AV node in case ablation of this is required for AF rate control. Despite these, outcomes of distal His bundle pacing from the ventricular aspect are less well defined.
Methods
We performed a retrospective review of patients who underwent conduction system pacing between January 2020 and October 2021 at our centre. During this period all procedures were performed employing a distal His bundle pacing approach with the lead placed on the ventricular aspect of the tricuspid annulus. Data was collected at implant, follow-up at 1 month and then every 6 months.
Results
Out of 35 patients, 33 underwent successful His bundle pacing (acute success rate of 94%), 1 patient had left bundle branch pacing and another patient had an unsuccessful procedure. Mean age was 74 years, median LVEF 45% and median pre-implant QRS was 108ms. 80% of the cohort had a history of AF. The indications for pacing were as follows: AF - for pace & ablate (60%); high grade AV block with narrow QRS and mild LVSD (17%); failed LV lead (14%); and other 9%. Mean procedure duration and fluoroscopy time were 78 minutes and 12.05 minutes, respectively. Median threshold at implant was 1.00V (IQR 0.719V). Selective His bundle pacing was achieved in 60% and non-selective in 34%. Mean follow-up duration was 150 days with median threshold at last f/up of 0.75V (IQR 0.750V). There were no acute procedural complications. 1 patient had a significant rise in threshold at follow-up and therefore required upgrade to CRT-P.
Discussion
Our data shows that distal His bundle pacing is a safe and effective technique for conduction system pacing. Thresholds appear stable at follow-up and failure rate was found to be comparable to biventricular pacing. We noted an initial learning curve for both implanter and physiologists with relatively poorer outcomes for the earlier cases. Longer term follow-up is ongoing, including functional assessment and follow-up to assess for remodelling with echocardiography. Prospective randomised trials are needed to compare conduction system pacing vs RV pacing in AF patients with HFpEF or mild LVSD undergoing AVN ablation, and vs biventricular pacing in the severe LVSD population.

Introduction
Many patients with atrial fibrillation (AF) do not benefit from rhythm control due to failed catheter ablation, advanced left atrial disease and comorbidities. "Pace and AV node (AVN) ablation" strategy is often adopted for rate control but with a substantial risk of pacing-induced cardiomyopathy. His bundle pacing (HBP) enables physiological biventricular activation through the His Purkinje conduction system. However, the proximity of the HBP lead to the site of AV node ablation may potentially compromise lead integrity in patients who undergo conventional HBP and AVN ablation. Therefore, we have modified HBP by placing the HBP lead distally at the ventricular side of the His bundle (D-HBP) before AVN ablation in patients with symptomatic AF. All patients had a backup RV lead.
Method
Patients who had D-HBP as part of a "Pace and AVN ablation" strategy were retrospectively analysed. Implant and device clinic follow-up data were collected and analysed.
Result
Twenty-one patients who had "pace and AVN ablation strategy" with D-HBP between 26th February 2020 and 3rd November 2021 were included. They had a mean age of 75 ± 1.4 years (mean ± SEM), NYHA class of 2.1 ± 0.2, QRS duration of 106 ± 5.3ms and 50% had at least moderately impaired LV systolic function. Seventeen patients (81%) had narrow QRS duration. D-HBP was successful in twenty of twenty-one patients (95%). At D-HBP implant, the mean acute threshold of the HBP lead was 0.96 ± 0.12V at 0.5 ± 0.05ms and the mean HBP lead impedance was 548.1 ± 29.5Ω. Selective HBP pacing was observed in thirteen of twenty patients. The mean QRS duration of HBP paced beats was 104.5 ± 4.7ms. Failure to capture the His bundle was observed in one patient. AVN ablation was performed on the same day after D-HBP in eleven patients and as a subsequent procedure in nine patients. The mean duration of procedure and fluoroscopy for D-HBP were 77.4 ± 4.6 minutes and 11.9 ± 1.4 minutes respectively. There were no acute procedural complications with no lead damage, displacement or lead perforation observed. The median follow-up period was 207 days. The mean D-HBP lead threshold following AVN ablation was 1.1 ± 0.2 V at 0.6 ± 0.07 ms and the mean lead impedance was 433.8 ± 20.7Ω, which were similar to before AVN ablation. One patient was reprogrammed with RV pacing only for elevated HBP lead threshold after AVN ablation to 4.2 V at 1ms. The mean D-HBP percentage was 92.3 ± 6.6% and the mean estimated battery longevity of the pacemaker was 7.9 ± 0.6 years at the last follow up. There was improvement in heart failure symptoms in eight patients from previously symptomatic to NYHA class I following D-HBP and AVN ablation.
Conclusion
D-HBP appear to be safe with potentially more favourable lead parameters than conventional proximal HBP in patients with symptomatic AF offered "Pace and AVN ablation" strategy.

Background Cardiac sarcoidosis (CS) with right ventricular (RV) involvement may mimic ARVC. Histopathological differences may result in disease specific RV activation patterns, detectable on the 12-lead electrocardiogram (ECG). Scar in ARVC progresses from epicardium to endocardium and may lead to delayed activation of areas with reduced voltages, translating into terminal activation delay and occasionally an (epsilon) wave with small amplitude on the ECG. On the contrary, patchy transmural RV scar in CS may lead to conduction block, and therefore late activated areas with preserved voltages, reflected as preserved R’-waves in the right precordial leads.
Purpose To determine whether the terminal activation patterns in precordial leads V1-V3 distinguish CS with RV involvement from ARVC.
Methods This is a multicenter retrospective study including patients with either 1) CS with RV involvement or 2) gene-positive ARVC referred for VT ablation. A non-ventricular paced 12-lead surface ECG prior to ablation was obtained (25mm/s and 10mm/mV). For detailed analysis, Leiden ECG Analysis and Decomposition Software (LEADS) was used. After detection of QRST complexes in the spatial velocity signal, LEADS generates a representative and low-noise averaged beat. Then, measurements per lead were performed using the measurement tool in Adobe Pro DC. Based on the hypothesis that conduction block in CS will lead to late activated areas with preserved voltages, we measured the surface area (SA) of the R’-wave in V1-V3. An R’-wave was defined as any positive deflection from baseline after an S-wave.
Results 13 CS patients with RV involvement (54 ± 8years, 62% male) and 23 ARVC patients (37 ± 15years, 78% male) were included. A R’-wave in V1-V3 was present in all CS patients, compared to 11 (48%) of ARVC patients (p = 0.002). The maximum R’-wave SA in lead V1-V3 was 3.55 (IQR:2.18-5.81) mm2 in CS vs. 0.00 (IQR:0.00-0.43) mm2 in ARVC (p < 0.001; Figure A). By ROC-analysis, the maximum R’-wave SA in lead V1-V3 was an excellent discriminator (area under the curve 0.980 [95%CI: 0.945-1.000]). A cutoff of ≥1.65mm2 had a sensitivity of 85% and specificity of 96% for diagnosing CS. An algorithm was created including the presence of an R’-wave in V1-V3 and the SA of this R’-wave (Figure B). This was validated in a second cohort (18 CS and 40 ARVC) with 72% sensitivity and 88% specificity.
Conclusion Transmural RV scars in CS may cause localized conduction block, leading to late activated areas with preserved voltages, reflected as large R’-wave on the 12-lead surface ECG. An easily applicable algorithm including the surface area of the largest R’-wave in lead V1-V3 ≥1.65mm2 distinguishes CS from ARVC with good sensitivity and specificity. The QRS terminal activation in precordial leads V1-V2 may reflect disease specific scar patterns (for examples: Figure C). Abstract Figure

Abstract
Background
Adult patients with congenital heart disease and a systemic right ventricle (sRV) are prone to develop heart failure. Decreased heart rate variability (HRV), a measure of autonomic dysfunction, is associated with morbidity and mortality in patients with congestive heart failure. The standard deviation of all intervals between normal sinus beats (SDNN) is a HRV parameter commonly reported as an indicator of autonomic function in these patients. Data about HRV and its clinical implications in patients with a sRV are scarce.
Purpose
To compare HRV parameters between patients with a sRV and healthy controls, and to assess their association with clinical status.
Methods
All available 24-hour Holter monitoring records of sRV patients under follow-up in our center and one record per healthy control subject were analysed. Holters with non-sinus rhythm were excluded. Time and frequency domain parameters were calculated and compared between both groups. Clinical landmarks such as arrhythmias or an episode of congestive heart failure, which occurred up until the time of the ambulatory ECG, were combined in a clinical event score. Determinants of SDNN were investigated with mixed model linear regression in the patients and with multivariate linear regression in the controls. Baseline characteristics, medication use, global longitudinal strain, validity as measured with bicycle exercise testing, and the clinical event score were taken into account.
Results
113 Holters of 43 patients and 39 Holters of healthy controls were analysed. The patient group included 30 patients (70%) late after Mustard or Senning correction for transposition of the great arteries, and 13 patients with congenitally corrected transposition of the great arteries (30%). Age and gender were comparable in patients and controls. Several HRV parameters were significantly worse in patients compared with controls, including SDNN (138 in patients vs. 161 in controls, p=0.021). In the patients, clinical event score was the only significant determinant of a lower SDNN (p<0.001). In the controls, age was the only significant determinant of a lower SDNN (p=0.039).
Conclusion
Contrary to the healthy population, in patients with a sRV, HRV is associated with clinical status rather than age. This indicates that disease progression affects autonomic function more than ageing in this group. Further research is needed to clarify the relation between clinical outcome and autonomic function in sRV patients.

Abstract
BACKGROUND AND PURPOSE Growth of the core infarct during the first hours of ischemia onset is not well-understood. We hypothesized that factors other than time from onset of ischemia contribute to core infarct volume as measured by MR imaging. MATERIALS AND METHODS Prospectively collected clinical and imaging data of consecutive patients with stroke presenting between March 2008 and April 2013 with anterior circulation large-vessel occlusion and MR imaging performed within 6 hours from the time of onset were reviewed. The association of time from onset, clinical, and radiographic features with DWI volume was assessed by using χ(2) and Mann-Whitney U tests. RESULTS Of 91 patients, 21 (23%) underwent MR imaging within 0-3 hours from onset, and 70 (76%), within 3-6 hours. Median MR imaging infarct volume was similar in both timeframes, (24.7 versus 29.4 mL, P = .906), and there was no difference in the proportion of patients with large infarct volumes (≥70 mL, 23.8% versus 22.8%, P = .928). Using receiver operating characteristic analysis, we detected no association between the time from onset and MR imaging infarct volume (area under the curve = 0.509). In multivariate analysis, CTA collaterals (>50% of the territory) (adjusted OR, 0.192; 95% CI, 0.04-0.9; P = .046), CTA ASPECTS (adjusted OR, 0.464; 95% CI, 0.3-0.8; P = .003), and a history of hyperlipidemia (adjusted OR, 11.0; 95% CI, 1.4-88.0; P = .023) (but not time from stroke onset to imaging) were independent predictors of MR imaging infarct volume. CONCLUSIONS Collateral status but not time from stroke onset to imaging was a predictor of the size of core infarct in patients with anterior circulation large-vessel occlusion presenting within 6 hours from onset.

Abstract
Rothenberg et al called for caution in the palliative use of irinotecan, 5-fluorouracil (5-FU) bolus and leucovorin (IFL schedule), because of early treatment related deaths in C89803 and N9741 studies. The objective of our multicenter phase II study was to evaluate the efficacy and safety of the combination of 5-FU bolus, folinic acid (FA) and irinotecan as first-line chemotherapy for metastatic colorectal cancer. From December 1999 to June 2002 138 patients (pts) were treated. The chemotherapy regimen was as follows: irinotecan 125 mg/m2 i.v. over 90 min and 5-FU 500 mg/m2 preceded by FA 20 mg/m2, both given by bolus, weekly, for 4 weeks every 6 weeks. Treatment continued until disease progression or unacceptable toxicity. Total number of administered cycles was 404. Average dose intensity was 75%. 47 out of 131 evaluable pts achieved a complete (n = 6) or partial (n = 41) response, leading to an overall response rate (RR) of 36% [95% confidence interval (CI) 24% to 48%], stable disease was registered in 50 (38%). The estimated median time to progression and survival were 6.5 months (95% CI 5.2-9.4) and 16.6 months (95% CI 15.1-19.3) respectively. Two-year survival was 35%. Toxicity was well manageable. In 18 (13.8%) pts the chemotherapy was stopped because of toxicity. Treatment related death was not observed. Close clinical monitoring, early recognition of toxicity, immediate therapeutic intervention are recommended for pts receiving IFL. In our experience this regimen has manageable toxicity and appropriate level of dose intensity and seems to be a good option for first-line therapy in metastatic colorectal cancer.

Abstract
BACKGROUND Exercise training is beneficial in health and disease. Part of the training effect materialises in the brainstem due to the exercise-associated somatosensory nerve traffic. Because active music making also involves somatosensory nerve traffic, we hypothesised that this will have training effects resembling those of physical exercise. METHODS We compared two groups of healthy, young subjects between 18 and 30 years: 25 music students (13/12 male/female, group M) and 28 controls (12/16 male/female, group C), peers, who were non-musicians. Measurement sessions to determine resting heart rate, resting blood pressure and baroreflex sensitivity (BRS) were held during morning hours. RESULTS Groups M and C did not differ significantly in age (21.4 ± 3.0 vs 21.2 ± 3.1 years), height (1.79 ± 0.11 vs 1.77 ± 0.10 m), weight (68.0 ± 9.1 vs 66.8 ± 10.4 kg), body mass index (21.2 ± 2.5 vs 21.3 ± 2.4 kg∙m(-2)) and physical exercise volume (39.3 ± 38.8 vs 36.6 ± 23.6 metabolic equivalent hours/week). Group M practised music daily for 1.8 ± 0.7 h. In group M heart rate (65.1 ± 10.6 vs 68.8 ± 8.3 beats/min, trend P =0.08), systolic blood pressure (114.2 ± 8.7 vs 120.3 ± 10.0 mmHg, P = 0.01), diastolic blood pressure (65.0 ± 6.1 vs 71.0 ± 6.2 mmHg, P < 0.01) and mean blood pressure (83.7 ± 6.4 vs 89.4 ± 7.1, P < 0.01) were lower than in group C. BRS in groups M and C was 12.9 ± 6.7 and 11.3 ± 5.8 ms/mmHg, respectively (P = 0.17). CONCLUSIONS The results of our study suggest that active music making has training effects resembling those of physical exercise training. Our study opens a new perspective, in which active music making, additionally to being an artistic activity, renders concrete health benefits for the musician.

Abstract
Human papillomavirus (HPV) infection is associated with transformation and clonal expansion of infected epithelial cells, resulting in the production of a benign growth, i.e. a wart. Recently, however, HPV has emerged as the primary causative agent of cervical carcinoma, malignancy being associated with the presence of the viral genome (predominantly genotypes 16 and 18) in cancerous cells. The only HPV proteins reliably expressed in neoplastic lesions are the 'oncogenic' E6 and E7 proteins, that serve both as tumour-specific markers and potential targets for immunotherapeutic intervention. As intracellular (nuclear) proteins, the E6 and E7 gene products may be hidden from the humoral immune response. Attention has thus focused on the generation of a vaccine capable of inducing or stimulating a cellular immune response to HPV 16 and HPV 18 E6 and E7. Vaccine development has been constrained by the absence of an appropriate animal model, the oncogenic nature of E6 and E7 and technical difficulties associated with detection of cytotoxic T cell responses to these antigens. Despite these difficulties, vaccine strategies have now been devised based on immunisation with synthetic peptide, whole protein and a vaccinia virus recombinant. Phase I/II human clinical trials have been initiated, and preliminary results have demonstrated the induction of specific cellular immune responses after immunisation. The HPV-associated neoplasia in cervical cancer represents an excellent target for therapeutic intervention because the tumour-associated antigens are so clearly defined. As such, it provides an appropriate model for establishing the general principles of cancer immunotherapy in humans.

Abstract
BACKGROUND Food allergy affects approximately 5% of children and is the leading cause of hospitalization for anaphylactic reactions in westernized countries. The mucosal adjuvant cholera toxin induces allergic sensitization to co-administered proteins in mice, while feeding the protein alone induces oral tolerance. Intestinal γδ T cells could be of importance in the induction of oral tolerance. This study aims to investigate whether γδ T cells have functional relevance in food allergic sensitization. METHODS Changes in γδ T cells on days 1, 2, 3, and 7 after initiation of food allergy were evaluated using flowcytometry. Furthermore, the anti-γδ T-cell receptor (TCR) antibody UC7 was used to block the γδ TCR in mice in vivo, followed by sensitization to peanut. After 4 weeks, peanut-specific antibodies in serum and cytokine production in spleen were measured. RESULTS Induction of food allergy resulted in a profound decrease in the percentage of γδ T cells in intestinal tissues and Peyer's Patches, but not in mesenteric lymph nodes or spleen. This decrease could be detected from days 1 to 2 after the initiation of food allergy and the number of γδ T cells returned to normal on day 7. Blockade of the γδ TCR resulted in elevated food allergic responses upon sensitization with peanut characterized by increased IgE and Th2 cytokine production in splenocytes. CONCLUSION These results demonstrate a unique regulatory role of γδ T cells, suggesting that targeting γδ T cells in the intestine may contribute to strategies to prevent and possibly treat food allergy.

Abstract
BACKGROUND Accelerating the clearance of therapeutic monoclonal antibodies (mAbs) from the body may be useful to address uncommon but serious complications from treatment, such as progressive multifocal leukoencephalopathy (PML). Treatment of PML requires immune reconstitution. Plasma exchange (PLEX) may accelerate mAb clearance, restoring the function of inhibited proteins and increasing the number or function of leukocytes entering the CNS. We evaluated the efficacy of PLEX in accelerating natalizumab (a therapy for multiple sclerosis [MS] and Crohn disease) clearance and alpha4-integrin desaturation. Restoration of leukocyte transmigratory capacity was evaluated using an in vitro blood-brain barrier (ivBBB). METHODS Twelve patients with MS receiving natalizumab underwent three 1.5-volume PLEX sessions over 5 or 8 days. Natalizumab concentrations and alpha4-integrin saturation were assessed daily throughout PLEX and three times over the subsequent 2 weeks, comparing results with the same patients the previous month. Peripheral blood mononuclear cell (PBMC) migration (induced by the chemokine CCL2) across an ivBBB was assessed in a subset of six patients with and without PLEX. RESULTS Serum natalizumab concentrations were reduced by a mean of 92% from baseline to 1 week after three PLEX sessions (p < 0.001). Although average alpha4-integrin saturation was not reduced after PLEX, it was reduced to less than 50% when natalizumab concentrations were below 1 mug/mL. PBMC transmigratory capacity increased 2.2-fold after PLEX (p < 0.006). CONCLUSIONS Plasma exchange (PLEX) accelerated clearance of natalizumab, and at natalizumab concentrations below 1 mug/mL, desaturation of alpha4-integrin was observed. Also, CCL2-induced leukocyte transmigration across an in vitro blood-brain barrier was increased after PLEX. Therefore, PLEX may be effective in restoring immune effector function in natalizumab-treated patients.

Abstract
While most genitourinary (GU) medicine clinics achieve a high uptake for testing HIV in new patients, they may still miss testing those at highest risk. Point-of-care testing (POCT) and salivary samples are acceptable and feasible but have not yet been shown to increase uptake among high-risk patients (HRP). This study aimed to describe reasons why HRP decline HIV testing and whether offering POCT along with standard testing would increase the uptake of testing HIV in two London GU medicine clinics. Anonymous self-administered questionnaires were offered to all new and rebooked patients. Eight hundred and ninety-nine questionnaires were analysed of which 598 were HRP. Uptake of HIV testing was 77.1 % among HRP and 65.8% among the rest. A total of 51.1 % of HRP who declined HIV testing said they would be more likely to accept a POCT and 32.8% a salivary test. Introduction of rapid POCT for HIV would increase patient's choice and may increase the likelihood of HRP accepting an HIV test.

Abstract
PURPOSE To compare efficacy and tolerability of weekly irinotecan combined with 5-fluorouracil (5-FU) bolus and folinic acid (FA) regimen (IFL) versus biweekly irinotecan with infusional 5-FU and FA (FOLFIRI) in patients (pts) with advanced stage colorectal cancer. PATIENTS AND METHODS Treatments outcome of 86 pts (IFL - 38 pts, FOLFIRI - 48 pts) was evaluated. Chemotherapy regimens were as follows: IFL - intravenous (i.v.) infusion irinotecan 125 mg/m(2) over 90 min and 5-FU 500 mg/m(2) preceded by FA 20 mg/m(2) both given by i.v. bolus injection, all repeated on days 1, 8, 15 and 22 every 6 weeks; FOLFIRI - i.v. irinotecan 180 mg/ m(2) on days 1 and 15 with subsequent FA 200 mg/m(2) administered as a 2-hour infusion and i.v. bolus injection of 400 mg/m(2) 5-FU immediately followed by 22-hour i.v. infusion of 600 mg/m(2) 5-FU on days 1, 2, 15 and 16 every 4 weeks. Treatment continued until disease progression or unacceptable toxicity. RESULTS A total of 152 (mean - 4) IFL cycles and 328 (mean - 6) FOLFIRI cycles were administered. Average dose intensity was 0.8 and 0.78 respectively. Toxicities were mild and manageable for both regimens evaluated. Overall response rate was 36.8% in IFL arm and 44.7% in FOLFIRI arm. At the median follow-up of 16 months in IFL arm and 14 months in FOPFIRI arm the two year survival was 38% and 45%, the median survival was 18 months and 21.5 months, and the median progression free survival was 6 months and 9.4 months respectively. CONCLUSIONS In our experience, both IFL and FOLFIRI regimens have acceptable toxicity at a similar level of dose intensity. Compared to IFL, FOLFIRI seems to improve progression-free survival.

Abstract
BACKGROUND The aim of this study was to determine whether the outcome of patients with colorectal cancer who presented with bleeding and a history of anticoagulant treatment was different from those who did not have bleeding or previous anticoagulant treatment. METHODS This was a single institution, retrospective study of patients with colorectal cancer with and without a history of rectal bleeding and treatment with anticoagulants, assessed for age, gender, tumor site, stage, recurrence rate, and survival. RESULTS A total of 621 consecutive patients (309 men) with a mean age of 70 years (range, 36-94 years) diagnosed with colorectal cancer between 1998 and 2004 were studied. Of these, 149 patients (24%) were referred for symptoms of rectal bleeding and 161 patients (26%) had been previously treated with anticoagulants. A total of 592 patients (95%) underwent curative or palliative surgery; endoscopic polypectomy was performed in 3 cases only and in 26 patients (4%) surgery was not performed due to advanced disease or critical illness. Patients with bleeding and a history of anticoagulant treatment presented commonly with stage I cancer. In addition, tumor stage III was less common in patients with previous anticoagulant treatment irrespective of presenting signs. Disease-free and overall survival rates were similar in all groups, irrespective of bleeding at presentation or anticoagulant treatment. CONCLUSIONS Rectal bleeding and anticoagulant treatment do not affect the outcome of newly diagnosed patients with colorectal cancer.

Abstract
The objective of this study was to determine the clinical effectiveness of a prime-boost human papillomavirus (HPV) vaccine regimen. A nonrandomized phase II prime-boost vaccine trial was conducted. Women with biopsy-proven anogenital intraepithelial neoplasia (AGIN) 3 were vaccinated with three doses of a recombinant fusion protein comprising HPV 16, E6/E7/L2 (TA-CIN) followed by one dose of a recombinant vaccinia virus encoding HPV 16 and 18 E6/E7 (TA-HPV). Clinical responses were evaluated by serial photographs, symptomatology, and biopsies before and after vaccination. Twenty-nine women were vaccinated; 27 with vulval intraepithelial neoplasia 3 and 2 with vaginal intraepithelial neoplasia grade 3. Clinical responses were seen in five women (17%), with one complete and five partial responses. Fifteen women (62%) had symptomatic improvement. No serious adverse effects were recorded. This is the first trial of a prime-boost vaccination regimen using heterologous HPV vaccines (TA-CIN followed by TA-HPV) in the management of AGIN. Since the prime-boost approach in this cohort offered no significant advantages over single TA-HPV vaccination, there are no further studies planned using this protocol. Future studies are warranted to define responders to immunotherapy.

Abstract
The first generation of human cancer vaccines has been tested in phase III clinical trials, but only a few of these have demonstrated sufficient efficacy to be licensed for clinical use. This article reviews some of the mechanisms that could contribute to these limited clinical responses, and highlights the challenges faced for development of future vaccines.

Abstract
13079 Background: It has been postulated that antiangiogenic therapies are less susceptible to acquired resistance compared to conventional treatment strategies, which target genetically unstable tumor cells. However, resistance is commonly seen (pre)clinically. A better understanding of the underlying mechanisms is clearly needed to improve such therapies. Methods: We studied mechanisms of acquired resistance to low-dose metronomic (LDM) cyclophosphamide (CTX), the continuous or frequent administration of comparatively low doses of CTX with no extended breaks resulting primarily in antiangiogenic effects, by using LDM CTX relapsed/resistant variants obtained during prolonged in vivo therapy from the human prostate cancer cell line PC-3, which initially is highly responsive. The variants were analyzed for their growth characteristics, angiogenic “phenotype” and impact on circulating endothelial cells (CEC)/endothelial cell progenitors (CEP). Furthermore, we obtained microvessel density (MVD) counts of corresponding xenografts and analyzed in vitro resistance to 4-hydroxycyclophosphamide (4-OH-CTX), hypoxia, acidosis, and glucose as well as serum deprivation. Results: The resistant variants did not show consistent changes in their angiogenic “phenotype”. The decrease in MVD upon LDM CTX treatment was comparable to that obtained in xenografts from parental PC-3, which was reflected by similar changes in the number of CEC and CEP. Despite in vivo resistance to LDM CTX, there was no evidence of in vitro resistance of the variants to 4-OH-CTX. However, they exhibited increased tolerance to microenvironmental stress resulting from sustained antiangiogenic activity. Conclusions: In this model, resistance to LDM CTX develops despite sustained antiangiogenic activity. This provides further evidence that reduced vascular dependence of the tumor cell population may be a basis for the observed resistance. The administration of CTX in a LDM manner does not result in tumor cell CTX resistance, supporting the notion that LDM protocols target primarily the tumor vasculature. If confirmed in ongoing clinical metronomic chemotherapy trials, our results will have major implications for the management of patients that progress under such treatment.

Abstract
14049 Background: A phase II study was conducted to assess the efficacy and tolerability of combination therapy with cisplatin, epirubicin, oral UFT and leucovorin in patients (Pts) with metastatic gastric cancer. Methods: Pts with previously untreated metastatic or unresectable measurable gastric adenocarcinoma received cisplatin 60 mg/m2 and epirubicin 50 mg/m2 on day (d)1, UFT 300 mg/m2 was administered in conjunction with oral leucovorin 30 mg/day in divided daily doses d 1–22, followed by a 7-day rest period. Results: Thirty-nine pts were enrolled in this study. Two achieved a complete response and 13 a partial response, giving an overall response rate of 38.5%. Disease stabilization was achieved in further 16 pts (41%). Median time to progression and median survival were 6.4 and 10.7 months respectively. Grade 3/4 neutropenia, anemia, throbocytopenia, occurred in 10%, 5%, and 2% of pts respectively, and febrile neutropenia occurred in 7 pts (one episode each). Grade 3 diarrhea occurred in 5% of the pts. There were no treatment related deaths. Conclusions: Cisplatin, epirubicin, and oral UFT plus leucovorin, a convenient outpatient regimen, has significant activity and tolerable toxicities in pts with metastatic gastric carcinoma. No significant financial relationships to disclose.

Abstract
The development of effective strategies against cervical cancer in Africa requires accurate type specific data on human papillomavirus (HPV) prevalence, including determination of DNA sequences in order to maximise local vaccine efficacy. We have investigated cervical HPV infection and squamous intraepithelial lesions (SIL) in an unselected cohort of 1061 women in a rural Gambian community. Squamous intraepithelial lesions was diagnosed using cytology and histology, HPV was typed by PCR-ELISA of DNA extracts, which were also DNA sequenced. The prevalence of cervical HPV infection was 13% and SIL were observed in 7% of subjects. Human papillomavirus-16 was most prevalent and most strongly associated with SIL. Also common were HPV-18, -33, -58 and, notably, -35. Human papillomavirus DNA sequencing revealed HPV-16 samples to be exclusively African type 1 (Af1). Subjects of the Wolof ethnic group had a lower prevalence of HPV infection while subjects aged 25-44 years had a higher prevalence of cervical precancer than older or younger subjects. This first report of HPV prevalence in an unselected, unscreened rural population confirms high rates of SIL and HPV infection in West Africa. This study has implications for the vaccination of Gambian and other African populations in the prevention of cervical cancer.

Abstract
Human papilloma virus (HPV) found in 99.7% of cervical cancers represents an attractive immunotherapeutic target for novel adjuvant dendritic cell (DC) immunotherapy. DC primed with HPV antigens have been shown to be capable of inducing CTL responses powerful enough to eradicate established murine tumours expressing HPV16 antigen. The use of tumour lysate has been found to be an effective means of priming DC with tumour associated antigens in animal models and in clinical trials leading to significant anti-tumour responses. Autologous DC primed with sonicated HPV expressing tumour lysate have been shown to be capable of inducing HPV specific classes I and II T-cell immunity in a pilot clinical study.Synthetic double stranded polyribonucleotides are effective in vitro activation/maturation agents capable of inducing a stable mature DC phenotype producing high levels of IL12. However, the prototype polymer poly [I]:poly [G] has proved to be clinically toxic. Preliminary in vitro data have demonstrated that a novel clinically non-toxic analogue polymer poly [I]:poly [C(12)U] (Ampligen R) can effectively induce in vitro maturation of human monocyte derived DC with sustained bioactive IL12 production. Human monocyte derived DC primed with tumour lysate and matured with synthetic dsRNA may therefore offer an effective way of optimising Th1 specific anti-cancer T-cell responses in cancer patients. This strategy is currently being tested in a clinical trial in patients with cervical cancer.

Abstract
The ultimate target of anti-angiogenic drugs is the genetically stable, activated endothelial cell of a newly forming tumor blood vessel, rather than the genetically unstable tumor cell population per se. This led to the notion that acquired resistance to such drugs may not develop as readily, if at all. While there is some evidence that this lack of resistance development may be the case for some direct-acting angiogenesis inhibitors, it is becoming apparent that resistance can develop over time to many types of angiogenesis inhibitors including, possibly, some direct inhibitors, especially when used as monotherapies. Possible mechanisms for such acquired or induced resistance include: (i) redundancy of pro-angiogenic growth factors when the drug used targets a single such growth factor or its cognate endothelial cell-associated receptor tyrosine kinase; (ii) the anti-apoptotic/pro-survival function of growth factors such as VEGF, which, in high local concentrations, can antagonize the pro-apoptotic effects of various angiogenesis inhibitors; (iii) epigenetic, transient upregulation, or induction, of various anti-apoptotic effector molecules in host-endothelial cells; and (iv) heterogeneous vascular dependence of tumor cell populations. It is suggested that long-term disease control with anti-angiogenic drugs can be best achieved by judicious combination therapy. In this regard, the great molecular diversity of anti-angiogenic drug targets, in contrast to chemotherapy, makes this a particularly attractive therapeutic option, especially when approved, commercially available drugs considered to have anti-angiogenic effects are used in such combination treatment strategies.

Abstract
The production of cytotoxic T cells with specificity for cancer cells is a rapidly evolving branch of cancer therapeutics. A variety of approaches aim to amplify anti-tumour cytotoxic T cell responses using purified peptides, tumour cell lysates or recombinant HLA/peptide complexes in differing antigen presenting systems. Using a two-step biotin-streptavidin antibody targeting system, recombinant HLA-class I/peptide complexes were attached to the surface of B cells via the anti-CD20 B9E9-scFvSA antibody-streptavidin fusion protein. Flow cytometry with a conformation dependant monoclonal antibody to HLA class I indicated that targeted HLA-class I/peptide complexes remain on the surface of B cells in culture for periods in excess of 72 h. PBMCs were stimulated in vitro for 8-14 days using the autologous B cells as antigen presenting cells. Following a single cycle of stimulation specific cytotoxic T cell responses to targeted HLA-A2 complexes containing the M1, BMLF1 and Melan A peptides could be demonstrated by tetramer staining and Cr release assays. With the HLA-A2/BMLF1 complex up to 2.99% of CD8+ve cells were tetramer positive producing 20% lysis (E : T 10 : 1) of CIR-A2 target cells in an in vitro cytotoxicity assay compared to baseline levels of 0.09% tetramer +ve and 2% lysis in the unstimulated population. PBMCs from a healthy donor treated with two cycles of stimulations with targeted HLA-A2/Melan A complexes, demonstrated expansion of the melanA tetramer +ve population from 0.03% to 1.4% producing 15% lysis of Melan A pulsed target cells. With further consideration to the key variables of HLA/peptide complex density, the ratio of stimulator to effector cells and optimum cytokine support, this system should offer an easy and effective method for the in vitro amplification of specific cytotoxic T cell responses and warrants development for the in vivo induction of cytotoxic T cell responses in cancer therapy.
