Abstract
Abstract
Background
wide antral pulmonary vein (PV) catheter ablation (CA) in patients with atrial fibrillation (AF) is safe and effective when permanent trans-mural lesions are achieved without causing harm to surrounding anatomical structures. Atrio-esophageal fistula, due to its high mortality, is the most dreadful complication related to CA for AF, therefore alternative radiofrequency (RF) approaches to reduce or eliminate this complication are currently studied. The shallower but wider lesions of high power short duration (HPSD) ablation might represent a safe alternative.
Purpose
to compare the rate of thermal esophageal lesions in patients with paroxysmal and persistent AF undergoing CA assigned to the 2 different RF modality.
Methods
one-hundred patients with paroxysmal and 100 with persistent AF will be alternatively assigned to undergo CA with the FlexAbility™ (HPSD group: 70W, 41°, 8 seconds) or the TactiCath™ (LSI-group: 35W, 41°, LSI: 5-5.5 posterior wall, up to 6 anywhere else) catheter. A 3-D mapping system, a steerable sheath and adenosine-test (30mg) were used in all patients. Posterior wall (PW) isolation in addition to PV isolation was performed in all, and patients with persistent AF were additionally treated with mitral and cavotricuspid isthmus ablation. Insertion of an esophageal probe was always attempted, and all patients underwent upper endoscopy 24 to 48 hours after CA.
Results
between June and October 2019, 71 patients (68 ± 10 years old, 32 (45%) female, 44 (60%) paroxysmal AF, AF duration 58 ± 81 months) were alternatively assigned to HPSD (36, 51%) or LSI-guided (35, 49%) ablation. No differences in clinical characteristics were found between groups. After 45 ± 18min and 30 ± 14 min of procedural and RF time, all PVs were isolated, and all spontaneous and adenosine-induced reconnections treated. Successful PW isolation was achieved with an additional 8 ± 3 and 7 ± 3 min of procedural and RF time. When HPSD and LSI-guided groups are compared, a similar rate of clinically non-relevant and self-healing thermal lesions at endoscopy was found (10, 27.8% vs. 10, 28.6%). Independent of the treatment group, a higher peak temperature identified patients with esophageal lesions (43.2° vs. 42°; P=.0065). A peak temperature value of 43.1° best identify patients most likely to develop thermal lesions (AUC 0.71, SE 84%, SP 39%). Interestingly, none of the 11 patients in whom esophageal probe insertion was not possible or attempted developed thermal lesions in comparison to 20 (33%) patients who underwent esophageal temperature monitoring (P=.0046). Conclusions: no difference in thermal induced esophageal lesions were found when the two different RF approach (HPSD vs. LSI guided) were compared. Interestingly, lack of temperature monitoring with an esophageal probe is associated with no thermal lesions at endoscopy.

Abstract
Abstract
Objective
The Trail Making Test B:A ratio is an embedded validity indicator (EVI) for neuropsychological assessment (NA; Ruffolo, Guilmette, & Willis, 2000). Recent literature supports D-KEFS Trail Making Test Conditions 4:2 (analogous to B:A) ratio (D-KEFS 4:2) as an EVI (Erdodi et al., 2018). The present study sought to assess the utility of D-KEFS 4:2 as an EVI for youth populations, using the Test of Memory Malingering (TOMM) to operationalize effort.
Method
102 children (81.2% male, Mage = 11.88) completed a NA, including D-KEFS 4:2 and TOMM. Receiver operator characteristics (ROC) curve analysis calculating Area Under the Curve (AUC) determined whether D-KEFS 4:2 accurately categorized participants’ effort (represented by TOMM performance).
Results
D-KEFS 4:2 (cut-off = 1.60: Erdodi et al., 2018) produced sensitivity of 9.09% and specificity of 91.25% in predicting TOMM performance on Trial 1 (TOMM1; AUC = 0.488) and 0.00% and 91.09% in predicting Trial 2 (TOMM2; AUC = 0.772). As a TOMM2 cut-off of 49 is suggested as more sensitive to inadequate effort, another analysis showed D-KEFS 4:2 yielded sensitivity of 33.33% and specificity of 91.92% (AUC = 0.710) in predicting TOMM2 performance with the more conservative cutoff.
Conclusions
This study suggests that D-KEFS 4:2 is an adequate EVI in predicting suboptimal effort when operationalized by TOMM performance, particularly when more conservative TOMM cutoffs are used. D-KEFS 4:2 detected true effortful performance with excellent specificity but exhibited poor detection of suboptimal performance. As a result, D-KEFS 4:2 has utility as an EVI in youth populations, but should not be used independently.

Abstract
Background Empirical knowledge around palliative care provision and needs of people with intellectual disabilities is extremely limited, as is the availability of research resources, including expertise and funding. This paper describes a consultation process that sought to develop an agenda for research priorities for palliative care of people with intellectual disabilities in Europe. Methods A two-day workshop was convened, attended by 16 academics and clinicians in the field of palliative care and intellectual disability from six European countries. The first day consisted of round-table presentations and discussions about the current state of the art, research challenges and knowledge gaps. The second day was focused on developing consensus research priorities with 12 of the workshop participants using nominal group technique, a structured method which involved generating a list of research priorities and ranking them in order of importance. Results A total of 40 research priorities were proposed and collapsed into eleven research themes. The four most important research themes were: investigating issues around end of life decision making; mapping the scale and scope of the issue; investigating the quality of palliative care for people with intellectual disabilities, including the challenges in achieving best practice; and developing outcome measures and instruments for palliative care of people with intellectual disabilities. Conclusions The proposal of four major priority areas and a range of minor themes for future research in intellectual disability, death, dying and palliative care will help researchers to focus limited resources and research expertise on areas where it is most needed and support the building of collaborations. The next steps are to cross-validate these research priorities with people with intellectual disabilities, carers, clinicians, researchers and other stakeholders across Europe; to validate them with local and national policy makers to determine how they could best be incorporated in policy and programmes; and to translate them into actual research studies by setting up European collaborations for specific studies that require such collaboration, develop research proposals and attract research funding.

Abstract
BACKGROUND Prehospital emergency medicine is a challenge for trainee emergency physicians. Rare injuries and diseases as well as patients in extreme age groups can unexpectedly face emergency physicians. In the regulations on medical education the German Medical Association requires participation in 50 emergency missions under the supervision of an experienced emergency physician. This needs to be improved because on-the-job training does not generally represent the whole spectrum of emergency medicine and a good and structured training under on call conditions is nearly impossible. AIM The subject of the model project described was whether practical training for emergency physicians can be achieved by participation in simulation training instead of real emergency situations. MATERIAL AND METHODS After modification of the Saarland regulations on medical education it was possible to replace up to 25 participations in emergency missions by simulation training. The concept of the course NASimSaar25 requires participants to complete 25 simulator cases in 3 days in small training groups. Emergency situations from all medical disciplines need to be treated. A special focus is on the treatment of life-threatening and rare diseases and injuries. Modern simulators and actors are used. The debriefings are conducted by experienced tutors based on approved principles. Medical contents, learning targets from the field of crew resource management (CRM) and soft skills are discussed in these debriefings. RESULTS Education in the field of emergency medicine can be improved by simulator-based learning and training. However, practical work under a tutor in real and clinical experience cannot be completely replaced by simulation. Simulator training can only be successful if theoretical knowledge has already been acquired. CONCLUSION A simulator-based course concept can result in an improvement of emergency medical education. The model project NASimSaar25 was well received by the target audience and mostly very well evaluated in terms of learning and reality. If this project becomes established the demand on simulation-based training will increase. The training should achieve a consistent standard of quality.

Abstract
BACKGROUND A substantial proportion of patients with gastro-oesophageal reflux disease (GERD) have only a partial response to proton pump inhibitor (PPI) therapy. Prokinetic drugs may improve reflux symptoms by enhancing oesophageal motility and gastric emptying. AIM To evaluate the effect of revexepride, a novel prokinetic 5-hydroxytryptamine type 4 (5-HT4 ) receptor agonist, compared with placebo, in patients with GERD who have a partial response to PPIs. METHODS A phase 2b, double-blind, parallel-group study was conducted, in which patients were randomised to one of three revexepride treatment groups (0.1, 0.5 and 2.0 mg three times daily) or placebo (1:1:1:1 ratio). Daily e-diary data captured patients' symptoms over an 8-week treatment period. The primary efficacy outcome was the weekly percentage of regurgitation-free days in the second half of the study (weeks 5-8). RESULTS In total, 480 patients were randomised and 477 received treatment (mean age 47.9 years; 61% women). The mean percentage of regurgitation-free days increased from baseline (range, 15.0-18.8%) to week 8 (62.3-70.5%) in all four study arms; however, there were no statistically significant differences in this change between placebo and the three treatment arms. No dose-dependent relationship in treatment effect was observed for any of the study endpoints. The incidence of treatment-emergent adverse events (TEAEs) was revexepride dose-dependent. Only one serious TEAE occurred and none resulted in death. CONCLUSIONS Revexepride was no more effective than placebo in controlling regurgitation in patients with GERD symptoms partially responsive to PPIs. Revexepride was well tolerated.

Abstract
Our study compares the histological and immunohistochemical cellular composition of two different chondrocyte-seeded biomaterials and the results of their transplantation. Our study cohort included 21 patients, comprising 19 men and two women with a mean age of 32 years, who were affected by single chondral lesions of the femoral condyles. These patients were enrolled in our study and treated with arthroscopic implantation of the tissue Hyalograft C and/or Brno culture. Brno culture bioengineered with a fibrin-based scaffold contains round cells showing features of differentiated chondrocytes expressing S-100 protein and α-smooth muscle actin. In contrast, in the case of Hyalograft C, the scaffold was made up of a fibrillar network composed of biomaterial fibres of the esters of hyaluronic acid and cells resembling fibroblasts and myofibroblasts and expressing only α-smooth muscle actin. The average size of the defects was 2.5 cm2. Patients were evaluated using the standardized guidelines of the International Knee Documentation Committee. During the comparison of bioptic samples obtained from both patient cohorts, we did not observe any important differences in the histological makeup of the newly formed cartilage. The histological analysis of these two groups of homogeneous patients shows that this bioengineered approach, under proper indications, may offer favourable and stable clinical results over time, in spite of the different matrix and cellular composition of the two transplants used.

Abstract
BACKGROUND Infliximab is typically administered intravenously via 2- to 3-h duration infusions. Infusions are time-consuming and costly. Shorter duration infusions are administered at some centres. Limited safety data are available on shorter duration infusions. AIM To determine risk of infusion reaction associated with standard 2- to 3-h infusions vs. rapid infusions in patients receiving infliximab therapy for inflammatory bowel disease (IBD), rheumatoid arthritis, spondylarthopathy and psoriatic disease. METHODS MEDLINE, Embase, and Web of Science were searched. Inclusion required human subjects, documentation of number of standard and rapid infliximab infusions and number of incident infusion reactions. Studies of overlapping populations were excluded. Three reviewers independently extracted data. Study quality was assessed. Relative risk (RR) was pooled using random effects models. RESULTS We identified 10 studies comprising 13 147 standard 2- to 3-h and 8497 ≤ 1-h infliximab infusions. Nine studies reported the risk of infusion reaction in standard vs. 1-h infusions, demonstrating decreased RR of infusion reaction with 1-h vs. standard infusions (0.9% vs. 2.2% of infusions; RR = 0.48, P = 0.009). Seven studies limited to IBD also demonstrated decreased risk of reaction (RR = 0.49, P = 0.002). Other comparisons demonstrated no difference in RR of reaction, including concomitant medication use (P = 0.30) or analysis limited to high and medium quality studies (P = 0.07). CONCLUSIONS Rapid infliximab infusions of ≤1-h duration are not associated with increased risk of infusion reaction when compared to standard 2- to 3-h infusions in selected patients who previously tolerated three to four standard infusions. One-hour infusions will conserve health care resources and may lead to improved adherence and quality of life in patients receiving infliximab.

Abstract
BACKGROUND Influenza is a potentially life-threatening illness that affects approximately 10% of the population annually, with resulting personal misery and societal disruption. Oseltamivir is a novel influenza treatment that has been extensively investigated. We describe a series of retrospective analyses investigating various measures of clinical efficacy across different populations of influenza-infected patients enrolled in studies of oseltamivir (Tamiflu((R))) that were conducted within the clinical development programme. METHODS Adolescents and adults (13-97 years, n = 4015) presenting within 36 hours of onset of influenza symptoms were randomised to receive oseltamivir 75mg or placebo twice daily for 5 days during local influenza outbreaks. Of these patients, 2413 had laboratory-confirmed influenza and are included in the analysis. Approximately 30% (n = 739) of patients were 'high risk'; 20% were healthy elderly subjects (n = 488) and 10% (n = 251) were patients with chronic respiratory and/or cardiac conditions. The primary endpoint was time to alleviation of a seven-symptom cluster in influenza-infected patients. Supplementary analyses were conducted using a variety of illness definitions and symptom clusters to investigate the sensitivity of the assessment of overall efficacy to differing disease definitions and also to explore efficacy in important subpopulations. RESULTS A total of 2413 patients had confirmed influenza infection (placebo: n = 1063; oseltamivir: n = 1350). Across all populations, the time to alleviation of illness was reduced by 19% (median duration 100.6 hours [95% CI 94.8-104.7]) compared with placebo (124.5 hours [95% CI 117.7-132.3], p < 0.0001). Oseltamivir recipients returned to normal health status, regained ability to perform usual activities and regained normal sleep patterns significantly faster than placebo recipients. The median duration of troublesome influenza symptoms was significantly reduced by oseltamivir treatment, e.g. fatigue by 29% and myalgia by 26% (both p < 0.0001). After 48 hours of treatment, 57% more placebo than oseltamivir recipients remained febrile, despite greater use of acetaminophen by placebo recipients. In addition, the median duration of acute febrile illness was significantly shortened by oseltamivir treatment compared with placebo in patients with cardiac disease (44.0 hours vs 64.7 hours, p = 0.026) or chronic obstructive airways disease (37.9 hours vs 53.8 hours, p = 0.004).Efficacy was similar among influenza A- and influenza B-infected patients. Oseltamivir was well tolerated, with transient gastrointestinal effects (observed in one in seven oseltamivir-treated patients compared with one in 12 patients on placebo) that only rarely resulted in study discontinuation. CONCLUSIONS Oral oseltamivir is a well tolerated and effective treatment for influenza in adolescents and adults, including the elderly and patients with chronic cardiac and/or respiratory disease.

Abstract
It is widely recognized that the accuracy of colocalization measurements is dependent upon the quality of the source images. We demonstrate that, as the image quality increases, the measured colocalization, using the Pearson and Spearman rank correlation coefficients, approaches the true colocalization asymptotically. This means that in practice it is difficult to obtain images of sufficient quality for accurate measurements. We introduce the replicate-based noise corrected correlation (RBNCC) which aligns the measured colocalization with the true colocalization: a noise measurement is made for each fluorophore from a pair of replicate images, the two noise measurements are combined to generate a correction factor which is applied to the measured colocalization between the two fluorophores. In consequence, accurate measurements can be obtained even with noisy images, making RBNCC especially attractive for live imaging. Even with images of apparently good quality we found an average discrepancy of about 20% between the measured and corrected colocalization. A case is made for using the Spearman rank coefficient instead of the Pearson coefficient to measure colocalization.

Abstract
A format is described for a scale bar that encodes the length represented within the structure of the bar itself, thereby removing the need for any supporting text. Although the 'unitary' scale bar has a conventional appearance it is also machine readable and therefore retains information about the scale even when the file format is changed. The format is based on the metre and is suitable for all terrestrial applications.

Abstract
6632 NCI has developed a central IRB (PedCIRB) to review NCI-sponsored pediatric clinical trials conducted by the Children's Oncology Group (COG). COG comprises ∼200 U.S. medical institutions and protocol activation traditionally requires separate protocol review by each local IRB (LIRB) and, subsequently, a review of each protocol amendment and significant adverse event. The PedCIRB model seeks to increase patient protection by improving the expertise of protocol reviewers and making their review available to all PedCIRB participating institutions. The PedCIRB consists of experts in pediatric oncology, pediatric medicine, nursing, pharmacy, bioethics, biostatistics, as well as patient advocates and childhood cancer survivors. The PedCIRB model also eliminates redundant reviews, reduces administrative burdens on local COG investigators and LIRBs, and can accelerate the pace of local protocol activation, thus increasing the availability of clinical trials to children with cancer. The PedCIRB conducts a full board protocol review that is available via a confidential website to participating LIRBs. LIRBs can choose to perform a facilitated review, using PedCIRB materials, that focuses on local concerns, rather than a full LIRB protocol review. If the LIRB accepts the PedCIRB review, the PedCIRB becomes the IRB of record for that protocol and takes responsibility for the review of subsequent protocol amendments, adverse events and continuing reviews. Since starting in November 2004, the PedCIRB has reviewed 59 protocols. Initial reviews resulted in 44 approvals pending modification and 15 protocols being tabled for further information. The time from protocol submission to final approval by the PedCIRB has ranged from 3 to 28 weeks with an average time of 16.9 weeks during year one and 12.7 weeks during year two of the project. As of November 2006, 117 of a possible 197 U.S. COG institutions (59%) have signed on to the PedCIRB initiative and 70% of the participating institutions have conducted facilitated reviews (total 750) for the 30 protocols available on the PedCIRB website. The PedCIRB's influence on protocol development and patient accrual timelines will be discussed. No significant financial relationships to disclose.

Abstract
In robotic radiosurgery, a focused beam of radiation is moved by a robot arm. We investigated methods for soft-tissue navigation using robotic radiosurgery. In previous work we described a method for real-time tracking based on correlation between the motion of implanted fiducial markers and external skin markers. In this work we extend our method of correlation-based tracking to tracking without implanted fiducials. We propose to use deformation algorithms on CT data sets combined with registration of digitally reconstructed radiographs and intra-treatment X-ray images to obtain intermittent information on the target location. This information is then combined with our basic correlation method to achieve real-time tracking. Our study investigates the feasibility of this approach from the point of view of computing time and required level of user interaction. The term 7D registration is coined to describe the underlying method for performing this task.

Abstract
PURPOSE OF THE STUDY The authors present the results of surgical treatment of talar dome cartilage defects. They used the transplantation of autologous cultured chondrocytes in the form of a solid chondral graft. MATERIAL AND METHODS Patients with chondral lesions categorized as grades II to IV by the Anderson classification or as grades II to IV by the Berndt and Harty classification were indicated for this treatment. After preoperative MRI examination, a small sample of healthy cartilage was harvested arthroscopically from the non-weight-bearing area of the talus and was sent to the Tissue Bank in Brno for chondrocyte cultivation. After 28 to 42 days the cultured chondrocytes were formed into a solid chondral graft, implanted at the damaged site of the talar dome and fixed with fibrin glue (Tissucol). RESULTS Between July 2003 and October 2005 five patients, three males and two females, were treated using this method. Their age ranged from 22 to 46 years. Follow-up was 6 to 24 months, with an average of 12.6 months, and the patients were examined by MRI at 2 weeks, 2 and 6 months and at 1 year. The clinical results were evaluated on the basis of the Mazur and Weber scoring systems. CONCLUSIONS A significant improvement in clinical function of the ankle joint was achieved in three patients and the condition remained unchanged in one patient. In one patient, the surgical outcome was too recent for evaluation, but the MRI results indicated tendency to good incorporation of the graft.

Abstract
PURPOSE OF THE STUDY The aim of this study was to present the results of treatment of deep chondral defects of the patella by transplantation of a solid chondral graft formed by autologous cultured chondrocytes. MATERIAL AND METHODS Indications for autologous chondrocyte implantation most frequently included acute trauma to the knee, particularly the patella, which resulted in a severe focal cartilage defect. The lesions were assessed on the basis of the Bessette and Hunter classification preoperatively, and on the Outerbridge classification during arthroscopy. A sample of healthy cartilage was harvested from a non-weight-bearing area of the trochlea femoris. After cultivation of chondrocytes for 28 to 42 days in the tissue bank, a solid chondral graft, prepared with the use of fibrin glue (Tissucol), was ready for implantation. RESULTS Six patients, two males and four females (average age, 21.1 years; range, 13 to 39 years) were treated by this method in the period from July 2003 to October 2005. Follow-up ranged from 1 to 25 months, with an average of 18.5 months. The patients were examined postoperatively by magnetic resonance imaging (MRI) at 2 weeks, 2 and 6 months, and at 1 year. The clinical results were evaluated by the Meyers, the Tegner and the Lysholm knee scoring systems. Two of the six patients, in whom the follow-up period was shorter than 6 months, were not included in the evaluation. CONCLUSIONS A significant improvement in knee function was recorded when the preoperative and final follow-up stages were compared, as well as on comparison with the healthy contralateral knee joint. MRI examination showed good graft incorporation in all patients.

Abstract
We present what is to our knowledge a first hardware realization of a simulated annealing algorithm in an adaptive optics system designed to image the retina of the human eye. The algorithm is applied to the retinal image itself without the need for wavefront sensors in the system. We find that this optimization algorithm can be an alternative to the traditional Hartmann-Shack sensing. We also compare the simulated annealing algorithm to the stochastic parallel gradient descent algorithm.

Abstract
BACKGROUND Following initial healing of erosive oesophagitis, most patients require maintenance therapy to prevent relapse. AIM To compare endoscopic and symptomatic remission rates over 6 months' maintenance therapy with esomeprazole or pantoprazole (both 20 mg once daily) in patients with healed erosive oesophagitis. METHODS Patients with symptoms of gastro-oesophageal reflux disease and endoscopically confirmed erosive oesophagitis at baseline were randomized to receive esomeprazole 40 mg or pantoprazole 40 mg for up to 8 weeks. Patients with healed erosive oesophagitis and free of moderate/severe heartburn and acid regurgitation at 4 weeks or, if necessary, 8 weeks entered the 6-month maintenance therapy phase of the study. RESULTS A total of 2766 patients (63% men; mean age 50 years) received esomeprazole 20 mg (n = 1377) or pantoprazole 20 mg (n = 1389) and comprised the intention-to-treat population. Following 6 months of treatment, the proportion of patients in endoscopic and symptomatic remission was significantly greater for those receiving esomeprazole 20 mg (87.0%) than pantoprazole 20 mg (74.9%, log-rank test P < 0.0001). Esomeprazole 20 mg produced a higher proportion of patients free of moderate to severe gastro-oesophageal reflux disease symptoms and fewer discontinuations because of symptoms than pantoprazole 20 mg (92.2% vs. 88.5%, P < 0.001). CONCLUSIONS Esomeprazole 20 mg is more effective than pantoprazole 20 mg for maintenance therapy following initial healing of erosive oesophagitis and relief of gastro-oesophageal reflux disease symptoms.
