Abstract Background Previous studies have suggested that proteinuria is independently associated with clinical outcomes in diabetic patients, irrespective of the presence of renal dysfunction. However, data regarding the impact of proteinuria on clinical outcomes in diabetic patients with atrial fibrillation (AF) are limited. Methods The Fushimi AF Registry is a community-based prospective survey of AF patients in our city in Japan. Follow-up data were available in 4,454 patients, and 634 diabetic patients with available data of proteinuria and estimated glomerular filtration rate (eGFR) were examined. We compared the clinical background and outcomes between patients with proteinuria (n=251) and those without (n=383). Then, we divided the patients into 4 subgroups according to the presence of proteinuria and renal dysfunction, and compared the clinical outcomes between groups; group 1 (without proteinuria, eGFR ≥60 ml/min/1.73 m2; n=203), group 2 (with proteinuria, eGFR ≥60; n=96), group 3 (without proteinuria, eGFR <60; n=180), group 4 (with proteinuria, eGFR <60; n=155). Results Age was comparable between patients with or without proteinuria. Patients with proteinuria had higher prevalences of previous heart failure (HF), stroke/systemic embolism, hypertension and renal dysfunction. The prevalences of previous myocardial infarction, and major bleeding were similar between two groups. During the median follow-up of 1,505 days, the incidence rates of HF hospitalization (4.1/100 person-years vs. 2.5/100 person-years; p<0.01) and cardiovascular death (1.8/100 person-years vs. 0.4/100 person-years; p<0.01) were higher in patients with proteinuria. When we divided patients into 4 subgroups, the incidences of HF hospitalization (group 1: 1.8/100 person-years vs. group 2: 3.4/100 person-years vs. group 3: 3.8/100 person-years vs. group 4: 4.9/100 person-years; p<0.01) and cardiovascular death (group 1: 0.3/100 person-years vs. group 2: 1.8/100 person-years vs. group 3: 0.5/100 person-years vs. group 4: 2.2/100 person-years; p<0.01) tended to be higher in not only group 3 and group 4 but also group 2 than group 1 (Figure). Multivariate Cox proportional hazards regression analysis including female gender, age (≥75 years), hypertension, pre-existing HF, renal dysfunction (eGFR <60),low left ventricular ejection fraction (<40%) and proteinuria revealed that proteinuria was an independent determinant of both of HF hospitalization (adjusted hazard ratio [HR]: 1.57, 95% confidence interval [CI]: 1.05–2.34) and cardiovascular death (HR: 3.76, 95% CI: 1.59–8.88). Figure 1 Conclusion In Japanese diabetic patients with AF, proteinuria was associated with higher incidences of HF hospitalization and cardiovascular death, irrespective of the presence of renal dysfunction.

Objective To determine the relationship between cartilage lesion etiology and clinical outcomes after second-generation autologous chondrocyte implantation (ACI) in the patellofemoral joint (PFJ) with a minimum of 2 years’ follow-up. Methods A retrospective review of all patients that underwent ACI in the PFJ by a single surgeon was performed. Seventy-two patients with a mean follow-up of 4.2 ± 2.0 years were enrolled in this study and were stratified into 3 groups based on the etiology of PFJ cartilage lesions: patellar dislocation (group 1; n = 23); nontraumatic lesions, including chondromalacia, osteochondritis dissecans, and degenerative defects (group 2; n = 28); and other posttraumatic lesions besides patellar dislocations (group 3; n = 21). Patient’s mean age was 29.6 ± 8.7 years. Patients in group 1 were significantly younger (25.4 ± 7.9 years) than group 2 (31.7 ± 9.6 years; P = 0.025) and group 3 (31.5 ± 6.6 years; P = 0.05). Body mass index averaged 26.2 ± 4.3 kg/m2, with a significant difference between group 1 (24.4 ± 3.2 kg/m2) and group 3 (28.7 ± 4.5 kg/m2; P = 0.005). A clinical comparison was established between groups based on patient-reported outcome measures (PROMs) and failure rates. Results Neither pre- nor postoperative PROMs differed between groups ( P > 0.05). No difference was seen in survivorship between groups (95.7% vs. 82.2% vs. 90.5%, P > 0.05). Conclusion Cartilage lesion etiology did not influence clinical outcome in this retrospective study after second generation ACI in the PFJ. Level of Evidence Level III, retrospective comparative study.

Aims The aim of this study was to investigate the impact of maturity status at the time of surgery on final spinal height in patients with an adolescent idiopathic scoliosis (AIS) using the spine-pelvic index (SPI). The SPI is a self-control ratio that is independent of age and maturity status. Patients and Methods The study recruited 152 female patients with a Lenke 1 AIS. The additional inclusion criteria were a thoracic Cobb angle between 45° and 70°, Risser 0 to 1 or 3 to 4 at the time of surgery, and follow-up until 18 years of age or Risser stage 5. The patients were stratified into four groups: Risser 0 to 1 and selective fusion surgery (Group 1), Risser 0 to 1 and non-selective fusion (Group 2), Risser 3 to 4 and selective fusion surgery (Group 3), and Risser 3 to 4 and non-selective fusion (Group 4). The height of spine at follow-up (HOSf) and height of pelvis at follow-up (HOPf) were measured and the predicted HOS (pHOS) was calculated as 2.22 (SPI) × HOPf. One-way analysis of variance (ANOVA) was performed for statistical analysis. Results Of the 152 patients, there were 32 patients in Group 1, 27 patients in Group 2, 48 patients in Group 3, and 45 patients in Group 4. Significantly greater HOSf was observed in Group 3 compared with Group 1 (p = 0.03) and in Group 4 compared with Group 2 (p = 0.02), with similar HOPf (p = 0.75 and p = 0.83, respectively), suggesting that patients who undergo surgery at Risser grade of 0 to 1 have a shorter spinal height at follow-up than those who have surgery at Risser 4 to 5. HOSf was similar to pHOS in both Group 1 and Group 2 (p = 0.62 and p = 0.45, respectively), indicating that undergoing surgery at Risser 0 to 1 does not necessarily affect final spinal height. Conclusion This study shows that fusion surgery at Risser 0 may result in growth restriction unlike fusion surgery at Risser 3 to 4. Despite such growth restriction, AIS patients could reach their predicted or ‘normal’ spinal height after surgery regardless of baseline maturity status due to the longer baseline spinal length in AIS patients and the remaining growth potential at the non-fusion levels.

Background: The incidence of atrial fibrillation (AF) is increasing in the elderly population, however, there is paucity of data on the safety outcomes of this patient subgroup thus we sought to investigate on the impact of age on the safety of catheter ablation for AF. Methods and Results: We included 1,293 (male 75%) patients enrolled in Yonsei AF Ablation Cohort database in Seoul, South Korea, from March 2009 to November 2013. We divided the patients into 4 groups according to age (Group 1, aged 17-49, N=295 ; Group 2 50-59, N=421; Group 3 60-69 N=408; and Group 4 ≥ 70, N=169) and evaluated the incidence of procedure related complications. No procedure-related death occurred in this study. There was a trend of increasing incidence of procedure related complications with age noted as follows: Group 1= 3.7%; Group 2= 4.0%; Group 3=6.6%; and Group 4 7.1%, (p= 0.15). There were 28 cases (2.2%) of major complications (Group 1=1.7%, Group 2=1.9%, Group 3=2%, Group 4 4.1%), tamponade being the most common. Major complications in group 4 include: tamponade 4 cases, phrenic nerve palsy 1 case, atrioesophaeal fistula 1 and 3rd degree AV block in 1 patient. Multivariate regression analysis shows ablation time (odds ratio (OR) 1.2 confidence interval (CI)1.0-1.017, p=0.017), procedure time (OR 1.008, CI 1.0-1.15, p=0.04), decreasing eGFR (OR 1.013, CI 1.002-1.026 p=0.018), coronary artery disease (CAD) (OR 1.847, CI 1.003-3.524, p0.04) and age (OR 1.028, CI 1.003-1.055, p=0.03) were associated with increased adjusted risk of total complications. Predictors of major complications include age (OR 1.044, CI 1.003-1.086, p0.02) and ablation time (OR 1.009, CI 0.999-1.000, p=0.033). Conclusion: Our data suggest that incidence of procedural complications in RFA of AF increase with age. Ablation time and age are independent predictors of a major complication.

Abstract Background Non-vitamin K antagonist (VKA) oral anticoagulants (NOACs) have substantially improved anticoagulation therapy for prevention of stroke and systemic embolism in patients with atrial fibrillation (AF), and available routine care data have so far broadly confirmed the safety of different NOACs in routine practice. However, such data for edoxaban are scarce, especially in extremely low and high body weight (BW). These extreme BWs may affect the bioavailability, distribution, and half-life of NOACs and, consequently, outcomes of treatment. Methods We analysed outcomes in normal-weight (BMI 18.5–25) vs overweight (BMI 25–30) and obese (BMI >30) patients enrolled into the ETNA-AF-Europe observational study (NCT02944019) collecting information on patients treated with edoxaban in 825 sites in 10 European countries. This snapshot analysis set includes data of 7,672 patients (56.3% of all enrolled patients) which have completed their 1-year follow-up visit (mean follow-up: 343.5 days). Results Median patient age was 74 years for all patients, 76 years for patients with a BMI 18.5–25 (group 1), 75 years for patients with BMI 25–30 (group 2), and 72 for patients with a BMI >30 (group 3). CrCl was 64 mL/min for patients with a BMI 18.5–25, 68 mL/min for patients with BMI 25–30, and 72 mL/min for patients with a BMI >30. The CHA2DS2-VASc (mean 3.1±1.38) and HAS-BLED (mean 2.5±1.10) score did not differ significantly between groups. As expected, diabetes and hypertension were significantly less prevalent in leaner patients and - accordingly - inversely correlated to age. There was no correlation between body weight and life-threatening bleeding (group 1: 0.28%; group 2: 0.40%; group 3: 0.14%). Also, stroke rates (group 1: 0.74%; group 2: 0.81%; group 3: 0.76%) did not differ between groups. Conclusion BMI, within the range here assessed, does not affect 1-year outcomes in European AF patients treated with edoxaban. Acknowledgement/Funding Daiichi Sankyo Europe GmbH, Munich, Germany

Abstract Background Catheter ablation (CA) for atrial fibrillation (AF) is a curable treatment option. However, AF recurrence after CA remains an important problem. Although the success rate has been improved after catheter ablation (CA) in patients with paroxysmal AF (PAF), outcome data after CA for persistent AF (PeAF) are highly variable. Previous studies showed the PeAF is one of independent predictors for AF recurrence in comparison to PAF. However, there are little information available on the prognostic significance of AF duration after CA for AF. The aim of this study is to evaluate the impact of AF duration on long-term outcomes of AF ablation in patients with PeAF compared with PAF. Methods We enrolled 778 consecutive patients, who were referred our institution between August 2015 and December 2017 for undergoing the first time CA for AF. We divided 5 groups (Group 1; PAF (n=442), Group 2; PeAF duration ≤6 months (n=198), Group 3; PeAF duration of 6 months to 2 years (n=87), Group 4; PeAF duration of 2–5 years (n=30) and Group 5; PeAF duration ≥5 years (n=21)). All patients followed up for at least 1 year. Outcome data on recurrence of AF after ablation were collected. Results There were no significant differences in baseline clinical characteristics before CA among 5 groups, except for the prevalence of congestive heart failure, left atrial diameter and left ventricular ejection fraction. During a mean follow-up period of 511±298 days, 217 patients had AF recurrence. Kaplan-Meier analysis revealed that AF recurrence was significantly higher in group 2 compared to group 1 (31% vs 20%, p=0.002) and in group 4 compared to group 3 (83% vs 30%, p<0.0001). However, AF recurrence was no significantly differences between groups 2 and 3 (31% vs 30%, p=0.76) and between groups 4 and 5 (83% vs 81%, p=0.45). Of 217 patients with AF recurrence, 154 patients had undergone multiple procedures. After last procedures, during a mean follow-up period of 546±279 days, 61 patients had AF recurrence. Kaplan-Meier analysis revealed that AF recurrence was significantly higher in group 2 compared to group 1 (10% vs 3%, P=0.0005) and in group 4 compared with group 3 (35% vs 10%, p=0.0001). However, AF recurrence was no significantly difference between groups 2 and 3 (10% vs 10%, p=0.91) and between groups 4 and 5 (47% vs 35%, p=0.47). AF Free Survival Curve Conclusion Although patients with PeAF within 2 years had significantly higher AF recurrence compared to PAF, AF ablation might still be a good contributor as the first line approach to improve outcomes in patient with PeAF within 2 years.

Abstract Chronic Myelogenous Leukemia (CML) originates in the chromosome (Ph1), a reciprocal translocation, corresponding to the BCR-ABL fusion oncogene. A small proportion (1–2%) of CML patients show breakpoints falling outside of the M-BCR gene on chromosome 22, leading to the synthesis of a variety of atypical BCR-ABL transcripts [either shortened: e1a2 (m-BCR), e6a2, e8a2, b2a3 (e13a3), b3a3 (e14a3), or elongated transcripts: e19a2 (m-BCR)] and to the synthesis of different BCR-ABL proteins. In this study, we retrospectively analysed the clinical characteristics and outcomes of cohorts of CML patients harbouring atypical transcripts in and treated with imatinib (IM). Twenty-two patients were analysed: 9 e1a2 [Group 1 (G1)], 4 e6a2 [Group 2 (G2)], 5 e19a2 [Group 3 (G3)], and 4 e8a2 [Group 4 (G4)] BCR-ABL transcripts. Two patients were in myeloid blastic phase at onset (1 in G1 and 1 in G2) and others in chronic phase. Age at diagnosis was significantly younger for e19a2 patients (39.5 years versus 64 for G1, 58.5 for G2, 72 for G3, p=0.005). Female patients were predominant for G1 (5F/3M), but not for other groups. All patients presented a classical Ph1 at karyotyping analysis at diagnosis, but 1 had a -7 (G1), 1 an additional t(11;16) with the Ph1 (G2), 1 a +8 (G3) and 1 a -Y (G3). The majority of patients presented typical CML features at diagnosis, however number of differences could be found: WBC counts were higher for e1a2 and e8a2 patients (74.2 109/l and 62.7 respectively vs 20.9 for G2, and 37.8 for G3, p&lt;0.03). A significant relative monocytosis was present for e1a2 patients (10% vs 4 (G2), 2.5 (G3), 5.5 (G4), p&lt;0.05), and a marked basophilia was present for e6a2 patients vs others (p&lt;0.0008). There was a trend for higher platelet counts in G3 vs others. Hasford and Sokal scores were somewhat comparable in all groups. Median follow-up since diagnosis was 24 months for G1, 10 for G2, 17 for G3 and 31 for G4. Only one patient received interferon for 7 months before IM (G1), all other patients did not receive any other treatment than hydroxyurea before IM. All patients were treated with IM alone initially at 400–600 mg/day. Median duration of IM was 18 months for G1, 9 for G2, 12 for G3, and 30 for G4. At time of analysis 1 pt in G2 and 1 patient in G3 died of progression (blastic phase), and the overall survival (OS) since IM start was better for e19a2 and e8a2 patients, but patients remain very few. However, these OS do not seem different from what has been observed for M-BCR transcripts (IRIS study). In conclusion, atypical BCR-ABL transcripts CMLs show particular diagnosis features, but their poor prognosis reputation seems abrogated by IM.

Abstract Abstract 4885 Introduction: Fludarabine has been reported to increase the incidence of relapse and histological transformation in chronic lymphocytic leukemia (Thornton PD, Leukemia research, 2005) and Waldenstrom macroglobulinemia (Leleu X, J Clincal Oncology, 2009). The purpose of our study was to investigate the role of Fludarabine and the risk of transformation and relapse in follicular lymphoma (FL). Patients and Methods: This is a retrospective single institution study. We included 50 patients consecutively diagnosed with FL Grade I and II based on WHO classification of lymphoid malignancies. Grade III patients were excluded from the study. Median follow up is 2.86 years. Patients were grouped according to the initial therapy chosen by their treating physicians: Group 1(n=14) included patients on observation and radiation therapy, Group 2 (n=6) included patients on Fludarabine based regimens, Group 3(n=13) included CVP-R and other rituximab regimens and Group 4(n=17) included R-CHOP. Data collected included time to the onset of biopsy proven transformation, time to relapse, mortality and overall survival. Level of significance was set at <0.05. Results: Median age of the patients was 56.5 and it was not significantly different for the various groups. High risk FLIPI score was seen in 66% of patients treated with Fludarabine regimens as compared to 61% of R-CHOP treated patients. Overall, relapse occurred in 38% patients and transformation occurred in 16% patients during the follow up period. Fludarabine treated patients had the highest relapse rate: 50% (p=0.03). R-CHOP group has lowest relapse rate: 11%. Transformation rate was highest in the Fludarabine group: 33%, as compared to 13% to 17% in other groups (p=0.10). Mortality rate was 7% in group 1, 16% in group 2, 23% for group 3 and 5% in group 4 (p=0.44). Time to relapse/progression in group 1 was 2.9 years; in group 2 was 2.1 years; in group 3 was 2.7 years and in group 4 was 5.8 years. Conclusions: In our study, Fludarabine treated patients appear to be at higher risk for relapse and transformation compared to patients treated with R-CHOP. The differences can not be explained on the basis of known prognostic factors such as age or FLIPI score. The retrospective nature of the study and the small numbers of patients preclude more definitive conclusions. Further research is needed with large number of patients. Disclosures: No relevant conflicts of interest to declare.

We carried out arthrography in 19 thumbs of 18 patients in whom duplication was observed at the interphalangeal (Wassel type II) or metacarpophalangeal (Wassel type IV) joints on radiographs. The average age at surgery was 12.3 months and average duration of post-surgical follow-up was 21.3 months. Based on the arthrographic findings, the types of cartilaginous connections were subdivided into five groups. In group 1, there was a cartilaginous connection at the base of duplicated phalanges. In group 2, there was a cartilaginous connection of the radial digit between the distal and proximal phalanges, or between the proximal phalanx and metacarpal. In group 3, the phalanges separated at a common joint without any cartilaginous connection. In group 4, the radial digit demonstrated fibrous attachment to the capsule without any joint formation. In group 5, each joint was completely separated without any cartilaginous connection. These arthrographic findings could not be detected on radiographs. Different surgical procedures were carried out according to the form of cartilaginous connection.

Introduction: The efficacy and safety of pulmonary vein isolation (PVI) for atrial fibrillation (AF) in the active duty (AD) military population has not been previously reported. Hypothesis: We postulate that PVI is an efficacious and safe treatment for young AD service members with AF. Methods: AD military personnel with AF who underwent PVI from 2004 to 2019 were retrospectively analyzed in four age groups (group 1, n=26, 18 to 27 years; group 2, n=38, 28 to 37 years; group 3, n=28, 38 to 49 years; group 4, n=12, ≥50 years). Primary endpoints were (1) PVI procedural efficacy defined as no or rare AF recurrence (<6 episodes) 12 months after last PVI with or without antiarrhythmic drugs (AAD) and (2) procedure-related adverse events and complications. Results: 104 personnel (mean age 35.6+9 years, 84.6% paroxysmal AF, mean LVEF 60.2+6%, 19.2% maintained on AAD after PVI) underwent 142 PVI procedures with a mean follow up of 55.8+47 months. Procedural efficacy was attained in 96.2% of group 1, 78.9% of group 2, 75.0% of group 3, and 66.7% of group 4 (P=0.004, Figure 1). Freedom from AF was reached in 80.3% of group 1, 55.3% of group 2, 46.4% of group 3, 41.7% of group 4 (P=0.02). AADs were maintained in 11.5% of group 1, 21.0% of group 2, 14.3% of group 3, 41.7% of group 4 (P=0.144) and there was no difference in AF recurrence rates between those with AADs and those without (P=0.091). LVEF <50% trended towards being a significant predictor of AF recurrence (OR, 7; 95% CI, 0.75-65; P=0.051). Complications occurred in only 4 (3.8%) cases (pulmonary vein stenosis, cardiac tamponade, arteriovenous fistula) with no complications in the youngest group. Conclusions: This study suggests that PVI is an effective and safe therapy for younger military personnel with AF desiring to decrease their individual AF burden.

Abstract Multiple myeloma remains one of the best indication for intensive chemotherapy followed by autologous hematopoietic stem cell transplantation (autoT). Intensive therapy followed by autologous transplantation is superior to conventional chemotherapy and it was demonstrated that two autoT were superior to one except for patients in very good partial response or in complete response after the first autotransplant. Peripheral blood stem cells (PBSC) can be used as well as bone marrow as HSC source with the same efficacy but very few data have been reported regarding PBSC recruitment. The main goal of our work was to study the impact on overall and event-free survival (OS and EFS) of PBSC recruitment using either growth factors (GF) alone (steady state) or chemotherapy followed by GF. Secondly, we performed a multivariate analysis studying influence on OS and EFS of sex, age, lines of therapy, pretransplant status, TBI, PBSC recruitment and number of autoT. We have analyzed 193 PBSC autoT (1 autoT=160, 2 autoT=33) performed for 160 MM patients [81 males and 71 females, mean age: 55 years (39–71)]. At diagnosis, 88 patients presented a MM Ig G (70k and 18l), 28 Ig A (16k and 12l), 3 Ig D (1k and 2l), 21 light chains k and 13 light chains l, 3 non secreting and 4 with plasmocyte leukemias. According to Durie and Salmon classification 75% of patients were in stage III, 15% in stage II and 10% in progressive I. Before transplantation, patients have received 1 line of poly-chemotherapy (n=141), 2 lines (n=15) or 3 lines (n=4) and 154 were evaluated for the response with 11 complete remission, 113 partial remission and 30 stable or evolutive disease just before transplant. As HSC (n=189), patients received PBSC which were recruited by GF alone (n=105) or cyclophosphamide+GF (n= 84). Conditioning (n=189),consisted in melphalan and TBI (n=51), melphalan alone (n=132), melphalan associated to cyclophosphamide or busulfan (n=6). We divided the population into 4 groups : group 1 who received one autoT of PBSC recruited by GF (n=76), group 2 one autoT of PBSC recruited by chemotherapy+GF (n=50), group 3 two autoT of PBSC recruited by GF (n=16) and group 4 two autoT of PBSC recruited by chemotherapy+GF (n=17). The median follow-up (FU) of the 4 groups were different with shorter FU (group 3: 9.9 months, group 4: 13 months) for patients who received tandem autoT because of the recent character of this strategy as compared to a long term follow-up for patients who received only one transplant (group 1: 35months, group 2: 55.3 months). Probabilities of OS and EFS at 2 years were 76% (95%CI 67–87) and 60% (95%CI 49.5–73) for group 1, 77% (95%CI 65–90.5) and 70% (95%CI 57.5–85) for group 2, 87.5% (95%CI 73–100) and 72.9% (95%CI 49–100) for group 3, 100% and 66.7% (95%CI 36–100) for group 4. The difference was not significant because of follow-up differences between the 4 groups and small number of patients in groups 3 and 4. In addition, multivariate analysis did not show any significant influence of the different studied parameters on OS and EFS. Nevertheless, because of these interesting preliminary results, a longer follow-up is warranted for definitive conclusions.
