Abstract Abstract 4364 Anticoagulation with dose adjusted vitamin-K antagonists (VKA, therapeutic range of the international normalized ratio (INR) of 2 to 3) and low dose aspirin (65 to 330 mg daily) enhance bleeding following tooth extraction. However, intensity of bleeding varies substantially between patients. Guidelines disagree regarding interruption or continuation of anticoagulation for tooth extraction. We hypothesized that personality traits may moderate bleeding intensity under anticoagulation. A total of 180 patients (77 female, 103 male, 49.9+15.3 years (mean, standard deviation)) underwent tooth extraction without interruption of anticoagulation. Sixty three patients did not take any anticoagulant (group 1), 60 patients were on aspirin (group 2), and 57 patients on VKA (INR 2–3, group 3). Patients completed a validated state-trait anxiety inventory (STAI), a personality inventory with 12 dimensions (Freiburg personality inventory (FPI)), and a self-developed questionnaire on general attitudes regarding general feeling and anxiety before tooth extraction. Dentists (JF, PH) rated bleeding intensity ranging from 0 to 9 according a standardized protocol. Intensity of bleeding after tooth extraction was higher in group 3 (score <5 in 40%, score >5 in 60% of patients) compared to groups 1 (40% and 60%) and 2 (53% and 47%) and higher in group 2 compared to group 1 (p<0.005, chi-square test) as expected. Higher anxiety values in STAI questionnaire correlated positively with higher bleeding scores (p<0.0001). High values of some of the FPI dimensions correlated positively with self-consciousness (p<0.0001), physical complaints (p<0.001), and emotionality (p<0.0001) life, and negatively with satisfaction (p<0.02) and extraversion (p<0.003) without differences between groups 1 to 3. Anxiety symptoms of the self questionnaire were identified as moderating factor on bleeding intensity following tooth extraction independently of anticoagulation (p<0.0001) according multinominal regression analysis. Other items of the self questionnaire such as physiological stress symptoms, regular performance of visits, bad experience with dentists, and pains during tooth extraction did not influence bleeding intensity. A short questionnaire is developed to identify the anxiety score of patients as a tool for a non pharmaceutical medical intervention to reduce bleeding complications following tooth extraction. Because differences of the moderating effect of bleeding by personality traits may exist between cultures, the questionnaire will be made available across countries www.blutverduennung.uni-hd.de Disclosures: No relevant conflicts of interest to declare.

Introduction: Among patients receiving vitamin K antagonists (VKA) therapy, maintenance of an international normalized ratio (INR) in the therapeutic range is essential for treatment efficacy and safety. This requires regular monitoring and appropriate dose adjustment. It has been reported that anticoagulation clinics should aim for a time in therapeutic range (TTR) between 70-80% to optimize benefit and minimize the risk of adverse events. Previously (in a study between September 2006 and June 2012), we have reported that patients with longer INR recall interval (4-8 weeks) showed no decrease of monitoring quality and that it would be safe to increase time between measurements. Aim: Since actual recommendations for improving TTR include shortening INR recall interval (Lip et al. 2018) we aimed to evaluate the quality of anticoagulation monitoring after having increased time between measurements beyond the 4-8 weeks recall interval. Methodology: We retrospectively analyzed 37931 appointments of 6 consecutive years (July 2012 to July 2018) corresponding to 1587 patients that are regularly followed up at an outpatient Anticoagulation Clinic of a central hospital under anticoagulation for at least 8 weeks, using TTR determined by Rosendaal method. Patients were divided according to target INR in three groups: Group 1 with target INR 2-3, including 1430 patients corresponding to 30743 appointments with mean age 69±15 years (mean±SD), majority (46.4%) with atrial fibrillation (AF); Group 2 with target INR 2.5-3.5, including 125 patients corresponding to 5439 appointments with mean age 67±12 years, majority (85.6%) with mechanical heart valves; Group 3 with target INR 3-4, including 32 patients corresponding to 1749 appointments with mean age 62±14 years, majority (62.5%) with antiphospholipid syndrome. Descriptive statistics (mean, standard deviation, minimum, maximum, chi-square), inferential statistics (t-test, A-Nova and effect sizes) tests and correlations were performed. Results: The 1587 patient population, 50.5% male, mean age of 68±17 years and 90.1% in Group 1, showed a mortality of 18%. A point-biserial correlation was run to determine the relationship between mortality and gender, age, INR group and diagnostic. Mortality was correlated with diagnosis (57.2% with AF) (rpb = -.071, n = 1587, p = .004), male gender (60%) (rpb = -.089, n = 1587, p <.001) and age (75±12) (rpb = .175, n= 1587, p<.001) but not with INR group (rpb = -.017, n = 1587, p = .499). Indeed, between groups mortality was not different [Χ2(2)=.492; p=.782; φ=.018] nor mean age [F(2, 1584)=2.588; p=.078; η2=.003], but gender distribution was unequal [Χ2(2)= 10.815; p=.004; φ=.083] with male predominating in Group 1 (51.9%) and female in Group 2 (60.8%) and 3 (65.6%). Patients in Group 1, corresponding to 90.1% of the total population, had TTR of 72%, patients in Group 2 had TTR of 69% and patients in Group 3 had TTR of 60%. Comparatively to the previous study (2006-2012), we noticed a significant decrease in patient population / appointments size (2087/ 61988) (p <.001) with a decrease of TTR in Group 1 (1927 patients) (83%) and Group 2 (120 patients) (74%) but a TTR increase in Group 3 (40 patients) (54%) (p <.001). Conclusions and Discussion: More than 90% of the population under VKA treatment showed effective TTR which may infer safety in increasing INR recall interval. The TTR decrease with a smaller population may be explained by the introduction of direct oral anticoagulants in patients with less comorbidities. The increase of TTR in patients with higher INR target suggests a better management of patients under VKA therapy that is actually the only choice for challenging patients.

Abstract Abstract 1925 In recent years, several pre-transplant models have been developed to predict the outcome after hematopoietic cell transplantation (HCT) through the selection of the best candidates and conditioning regimens. Two models are the most popular one each side of the Atlantic: the HCT Comorbidity Index (HCT-CI) and the European Blood and Marrow Transplantation (EBMT) score. Their predictive capacity has been demonstrated in several studies. Since these models are focused on different pre-HCT characteristics (HCT-CI on comorbidities and the EBMT score on more classical risk factors) we hypothesized that the combination of the two could improve their individual predictive capacity. To that end, we retrospectively analyzed pre-HCT characteristics of all consecutive patients receiving a reduced-toxicity allogeneic HCT (allo-HCT) in 4 Spanish centers from 1999–2008. The HCT-CI and the EBMT scores were calculated as originally defined. Patients were then classified according to the HCT-CI in the original categoriesas originally defined and regardingto the EBMT score in two groups according to the median score of the whole cohort. Multivariate analyseis including pre-HCT characteristics were performed using Cox proportional Hazard models and taking into account the competitive risk structure. The predictive capacity of each model was calculated using the c-statistics. Patients were included in the same protocol of reduced-toxicity allo-HCT with fludarabine-based conditioning in combination with melphalan (70–140 mg/m2) or busulfan (8–10 mg/kg). The median follow-up for survivors was 51 months (range 3–123). A total of 442 recipients (80% transplanted from HLA identical siblings) were included. Most frequent diseases were acute leukemia/MDS (n=156, 35%) and non-Hodgkin lymphoma/chronic lymphocytic leukemia (n=125, 28%). The HCT-CI score distribution was: score 0 (n=87, 20%), score 1–2 (n=130, 29%) and score ≥3 (n=225, 51%) while for the EBMT score was 0–2 (n=62, 14%), 3–4 (n=194, 44%) and >4 (n=187, 42%). The probability of 100-day Non-Relapse Mortality (NRM), 4y-NRM and 4y-overall survival (OS) for the whole cohort were 12% (95%CI 11–14), 35% (95%CI 33–38) and 45% (95%CI 48–50), respectively. In the multivariate analysis, the HCT-CI had and impact on 4y-NRM (score 0: HR 1.0; scores 1–2: HR 1.6 [95%CI 0.9–3], p=0.09; scores ≥ 3: HR 2.3 [95%CI 1.3–3.8], p=0.003) and 4y-OS (score 0:HR of death 1.0; scores 1–2: HR 1.3 [95%CI 0.8–2], p=0.2; scores >2: HR 1.9 [95%CI 1.3–2.8], p=0.002) while the EBMT score did not (p=0.4 and p=0.5, respectively). Using the two models we classified the patients were classified into 3 groups: patients with low HCT-CI (0–2) and low EBMT score (<4) (Group 1), patients with high HCT-CI or high EBMT score (Group 2) and patients with both high HCT-CI and EBMT score (Group 3). The HR for 4y-NRM were: group 1 (HR 1.0), group 2 (HR 1.1 [95%CI 0.6–2], p=0.7), group 3 (HR 1.8 [95%CI 1–3], p=0.04) and for 4y-OS was: group 1 (HR 1.0), group 2 (HR 1 [95%CI 0.6–1.5], p=0.8), group 3 (HR 1.6 [95%CI 1–2.3], p=0.04). Regarding the predictive capacity of each model, the HCT-CI alone captured 58% (c- 95%CI: 53–62), the EBMT score 54% (c- 95%CI: 51–58) while the combination of the two models captured 57% (c- 95%CI: 53–61) of the patients. Finally, the impact of EBMT score was explored in each HCT-CI group. In patients with HCT-CI scores of 0 and 1–2, the EBMT score did not have an impact on NRM and OS. In the cohort of high HCT-CI score (>2), patients with low EBMT score showed a trend to lower risk of NRM (HR 0.6 [95%CI 0.3–1], p=0.08) with a similar risk as for patients with HCT-CI of 1–2 (Figure 1). In conclusion, high HCT-CI scores but not high EBMT scores are associated with worse outcome in patients undergoing reduced toxicity allo-HCT. The addition of the EBMT score contributes little to the HCT-CI, except maybe for patients with more and severe comorbidities. Figure 1. Probability of NRM according to the HCT-CI for all patients and according to the EBMT score in the 225 patients with HCT-CI >2 (MVA) Figure 1.

Abstract Introduction: Hypogonadism, i.e. low total testosterone, is present in approximately a quarter of men older than 70 years (Harman SM et al, J. Clin Endo & Met, 2001, PMID 11158037 and Wu FCW et al, J Clin Endo & M et, 2008, PMID 18270261). Myeloma patients are known to suffer from fatigue and decreased functional performance, mood disturbances, and anemia; similar trends have been found in people with hypogonadism. Cytogenetically high risk myeloma characterized by the amplification of 1q21 is associated with increased serum levels of soluble IL-6 receptor (sIL-6r) (Stephens OW, Blood, 2012, PMID 22072558). We hypothesized that total testosterone levels will be associated with overall survival from the time of diagnosis, presence of 1q21 amplification by CD138-selected FISH, anemia, and anti-depressant use. Methods: The Buckeye Myeloma Registry (OSU 10115) opened in 2011 to enroll any patient with a plasma cell dyscrasia. Serum total testosterone was measured at the time of the initial clinic visit to the myeloma group at Ohio State. Less than 325 ng/dL was defined as the hypogonadal range, and testosterone was divided into <100 (group 1), 100-240 (group 2), 240-325 (group 3), and greater than 325 ng/dL (group 4), although normal testosterone decreases with age. Female patient testosterone levels were also analyzed and divided into <10 (group 1), 10-60 ng/dL (group 2), and >60 ng/dL (group 3). A retrospective chart review was initiated to review all myeloma patients with a serum testosterone drawn at the time of their initial clinic visit to OSU. Results: Among 418 male MM patients, median age was 65 y.o. (range 24-95), 86% were Caucasian and 14% African-American, and the distribution of ISS stage was 32% stage 1, 22% stage 2, and 19% stage 3 with 28% missing staging data. Cytogenetic data was missing from 28% of patients. Out of 418 male MM patients, 29 (7%) had serum testosterone <100, 202 (48%) with testosterone 100-240, 79 (19%) with testosterone 241-325, and 108 (26%) > 325 ng/dL. Out of 172 female MM patients, 44 (26%) had an undetectable serum testosterone, 120 (70%) with testosterone 10-60, and 8 (5%) with testosterone > 60. Among male MM patients, log-rank [Mantel-Cox] analysis of overall survival with serum testosterone including all 4 groups demonstrated no significant differences (p=0.917) with only 80 events. Among 275 male MM patients with cytogenetic information available, there was no correlation between presence of 1q21 trisomies or tetrasomies and overall survival (r=0.0714, p=0.238). There was a strong and expected correlation between testosterone and BMI (r=0.14, p=0.00468). Among 161 total female MM patients, log-rank analysis with serum testosterone including all 3 groups also demonstrated no differences (p=0.416) with only 29 events in total. Among 101 females with cytogenetic information, there was also no correlation with 1q21 amplification (r=0.0895, p=0.373). Conclusion: The majority of male MM patients (74%) have secondary hypogonadism and approximately half have total testosterone levels <240 ng/dL. Cox proportional hazards analyses of survival adjusted for significant univariate covariates will be presented at the meeting. Correlations with anemia and medication use (specifically opiates and anti-depressants) will also be presented at the meeting. Disclosures No relevant conflicts of interest to declare.

The aim of this study was to identify and compare any differences in the position of the anterior limit of the dentition provoked by three different types of orthodontic mechanics: traditional edgewise, straightwire and self-ligating. A sample of 54 patients (selected from a group of 289 patients) possessed a range of Little’s Irregularity Index values for the upper and lower dental arches between a minimum of 6.5 and a maximum of 13.5 at T0, and corresponding final values no greater than 2 and hence of minimal irregularity. The 54 patients were subdivided into three groups according to the type of brackets used in their treatment: Group 1 was composed of 24 patients treated using the self-ligating technique, Group 2 of 15 patients treated using a conventional straight-wire technique (Roth) and Group 3 of 15 patients treated using the standard edgewise technique. Cephalometric tracings were performed on laterolateral teleradiography. Group 1 value was found to be nonsignificant, whereas significant labial inclination was noted in Groups 2 and 3 (). A significant labial inclination of the upper incisors was also evidenced in all three sample groups.

Abstract Background. In chronic myeloid leukemia (CML), achievement of optimal responses by time point has improved long-term outcomes. In IRIS study, patients who achieved major molecular response (MMR) at 18 months had event-free survival (EFS) benefit, compared to those who achieved complete cytogenetic response (CCyR) without MMR. However, the best treatment for these patients is still not confirmed. By the previous studies, sustaining standard-dose of imatinib (IM) is expected to yield less than 20 percent of additive MMR. In this study, we investigated the efficacy of nilotinib (NIL) versus high-dose IM versus sustaining standard-dose IM for CCyR patients with suboptimal molecular response to frontline IM therapy. Methods. Early chronic phase (CP) CML patients who have achieved CCyR but no MMR after at least 18 months and up to 24 months ( 18 to 24 months) on first-line IM therapy at a daily dose of 400 mg were divided into 3 treatment groups; NIL 400mg BID (800 mg/day; group 1) vs IM 400 mg BID (800 mg/day; group 2) vs IM 400mg QD (400mg/day; group 3). Group 1 and 2 patients were selected in RE-NICE multicenter study and group 3 patients were selected with the same inclusion criteria of RE-NICE. The efficacy endpoints are MMR rate by 12 months and MMR rate and undetectable molecular residual disease (UMRD) rates by 36 months. Safety profiles of each group were compared. Patients showing lack of response (lack of complete hematologic response (CHR) at 6 months, increasing WBC, no major cytogenetic response (MCyR) at 24 months), loss of response (loss of CHR or MCyR) or intolerance to treatment were allowed to switch to other treatment. Results. With a data cut-off date of 17 Jul 2014, a total of 83 patients were evaluated; 29 patients in NIL group (group 1), 29 patients in high-dose IM group (group 2) and 25 patients in standard-dose IM group (group 3). With a median follow-up of 36 months (range, 1-63), all patients in group 1 remained in nilotinib treatment, 17 patients in group 2 switched to NIL 400mg BID due to intolerance (n=4) and lack of response (no MMR; n=13). In group 3, with a median follow-up of 71 months (range, 6-132), 15 patients switched to other treatment due to intolerance (n=5) and lack of response (no MMR; n=10). Up to now, all patients in three groups have maintained CCyR without progression or resistance. 10 in 29 (35%), 8 in 29 (28%) and 5 in 25 (20%) patients achieved MMR by 12 months, and 20 in 29 (69%), 15 in 29 (51%) and 11 in 25 (44%) patients achieved MMR by 36 months in group 1, group 2 and group 3 respectively. Overall, 3 patients in group 1 (3/29, 10%) achieved confirmed UMRD. Overall 3 years probability of MMR was significantly higher in group 1 than the other two groups (67.8% vs 41.0% vs 40.4%, group 1, 2, 3 respectively, group 1 vs 2, P=0.089, group 1 vs 3, P=0.035, group 2 vs 3, P=0.614). Compare to other groups, the patients in group 2 showed higher toxicities, such as leukopenia, anemia, thrombocytopenia, edema, fatigue, dyspnea and hypophosphatemia. Conclusions. Nilotinib 400mg twice daily treatment showed better efficacy than high-dose or same standard-dose imatinib for the treatment of patients who have suboptimal molecular response to initial standard-dose imatinib. Additionally, a switch to nilotinib in suboptimal molecular responder to imatinib would also be preferable option in terms of tolerability. Updated data with longer follow-up duration will be presented in the meeting. Disclosures No relevant conflicts of interest to declare.

Summary. Background: Prosthetic vascular graft infection (PVGI) is a complication with high mortality. Cyanoacrylate (CA) is an adhesive which has been used in a number of surgical procedures. In this in-vivo study, we aimed to evaluate the relationship between PVGI and CA. Materials and methods: Thirty-two rats were equally divided into four groups. Pouch was formed on back of rats until deep fascia. In group 1, vascular graft with polyethyleneterephthalate (PET) was placed into pouch. In group 2, MRSA strain with a density of 1 ml 0.5 MacFarland was injected into pouch. In group 3, 1 cm 2 vascular graft with PET piece was placed into pouch and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. In group 4, 1 cm 2 vascular graft with PET piece impregnated with N-butyl cyanoacrylate-based adhesive was placed and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. All rats were scarified in 96th hour, culture samples were taken where intervention was performed and were evaluated microbiologically. Bacteria reproducing in each group were numerically evaluated based on colony-forming unit (CFU/ml) and compared by taking their average. Results: MRSA reproduction of 0 CFU/ml in group 1, of 1410 CFU/ml in group 2, of 180 200 CFU/ml in group 3 and of 625 300 CFU/ml in group 4 was present. A statistically significant difference was present between group 1 and group 4 (p < 0.01), between group 2 and group 4 (p < 0.01), between group 3 and group 4 (p < 0.05). In terms of reproduction, no statistically significant difference was found in group 1, group 2, group 3 in themselves. Conclusions: We observed that the rate of infection increased in the cyanoacyrylate group where cyanoacrylate was used. We think that surgeon should be more careful in using CA in vascular surgery.

SummaryWe have previously shown abnormalities of haemostasis suggestive of intravascular coagulation in patients with malignant hypertension, a condition associated with retinopathy and renal fibrin deposition. To determine whether such abnormalities are specific to malignant hypertension, we have measured several haemostatic and haemorheological variables in 18 patients with malignant hypertension (Group 1), 18 matched healthy controls (Group 2), and 18 patients with non-malignant hypertension (Group 3) matched for renal pathology, blood pressure and serum creatinine with Group 1. Both Groups 1 and 3 had increased mean levels of fibrinogen, factor VIIIc, beta-thrombo- globulin, plasma viscosity and blood viscosity (corrected for haematocrit); and decreased mean levels of haematocrit, antithrombin III and platelet count. Mean levels of fast antiplasmin and alpha2-macroglobulin were elevated in Group 1 but not in Group 3. We conclude that most blood abnormalities are not specific to malignant hypertension; are also present in patients with non-malignant hypertension who have similar levels of blood pressure and renal damage; and might result from renal damage as well as promoting further renal damage by enhancing fibrin deposition. However increased levels of fibrinolytic inhibitors in malignant hypertension merit further investigation in relation to removal of renal fibrin.

The purpose of the study was to conduct a comparative assessment of the course of the postoperative period after phlebectomy and thermal ablation in patients with varicose veins of the lower extremities in the system of the great saphenous vein (GSV) with class C2 of chronic venous insufficiency (CVI) — CEAP class C2. Materials and methods: 455 patients (455 limbs) with CEAP class C2. Group 1 (n = 154) received stripping + minimally invasive phlebectomy; Group 2 — endovenous laser ablation (EVLA) of GSV trunk + sclerotherapy of varicose veins; 3 group (n = 150) — radiofrequency ablation (RFA) of the GSV + sclerotherapy. All patients were united by a single tactical solution — the elimination of pathological vertical reflux in GSV. In each group, patients were with similar hemodynamic profile were selected (Group 1 = 63; Group 2 = 61; Group 3 = 61). The course of the postoperative period (from 2 days to 2 months) was compared for pain (visual analog scale — VAS), clinical symptoms of chronic venous insufficiency, degree of satisfaction (Darvall questionnaire), and duration of disability. Statistical processing was carried out using Excel programs for Windows XP, MedCalc® (version 11.4.2.0., Mariakerke, Belgium). Results: Postoperative pain is more pronounced (during day 1 for Group 1–4.0, Group 2–3.0, Group 3–2.0) and more prolonged (up to 4 days) after open surgeries (p < 0.05). The dynamics of the clinical symptoms of CVI (including varicose syndrome and use of compression therapy) could not be fully evaluated in connection with the ongoing sclerotherapy procedures for patients of Groups 2 and 3. Satisfaction of patients with aesthetic aspects was higher than expected in all groups. Reliable statistical differences proved decrease in days of disability (Group 1–14; Group 2–4; Group 3–3) and earlier return to physical activities and work in patients after thermal ablation in comparison with phlebectomy. Conclusion: The study shows that all three methods for eliminating vertical reflux in the GSV can be proposed for a large category of patients with CEAP of class C3 and C2. Medical and social rehabilitation of patients using endovascular thermal ablation technologies proceeds faster, which is beneficial both for the patients and for society.

To identify the prevalence of early pathology of cardiovascular diseases, a survey of 400 200 girls) in the age group 15 and 17 years old was conducted as a part of routine medical of the level of blood pressure (BP) was carried out, with the calculation of the average level pressure on the basis of three separate measurements estimated by percentile tables for a registration of a standard resting ECG in 12 leads. According to the results of the survey, into 3 groups: with an increase in blood pressure above 95 ‰ (group 1 – 16 people), which recorded in males (p<0,05); Group 2 (67 people) – adolescents with a normal blood pressure level and group 3 of adolescents with a decrease in blood pressure below 5 ‰ changes in the form of rhythm and conduction disturbances were noted in almost every a predominance of sinus tachycardia in the first group. In the third group of adolescents, form of ectopic rhythm and pacemaker migration were significantly more frequently only 78 % of adolescents were referred for consultation and in-depth examination by a pediatric cardiologist.

Background: We hypothesized that perioperative HbA1c influenced the pattern and outcomes of Lower Extremity Amputation (LEA). Methods: A retrospective analysis was conducted for all patients who underwent LEA between 2000 and 2013. Patients were categorized into 5 groups according to their perioperative HbA1c values [Group 1 (<6.5%), Group 2 (6.5-7.4%), Group 3 (7.5-8.4%), Group 4 (8.5-9.4%) and Group 5 (≥9.5%)]. We identified 848 patients with LEA; perioperative HbA1c levels were available in 547 cases (Group 1: 18.8%, Group 2: 17.7%, Group 3: 15.0%, Group 4: 13.5% and Group 5: 34.9%). Major amputation was performed in 35%, 32%, 22%, 10.8% and 13.6%, respectively. Results: The overall mortality was 36.5%; of that one quarter occurred during the index hospitalization. Mortality was higher in Group 1 (57.4%) compared with Groups 2-5 (46.9%, 38.3%, 36.1% and 31.2%, respectively, p=0.001). Cox regression analysis showed that poor glycemic control (Group 4 and 5) had lower risk of mortality post-LEA [hazard ratio 0.57 (95% CI 0.35-0.93) and hazard ratio 0.46 (95% CI 0.31-0.69)]; this mortality risk persisted even after adjustment for age and sex but was statistically insignificant. The rate of LEA was greater among poor glycemic control patients; however, the mortality was higher among patients with tight control. Conclusion: The effects of HbA1c on the immediate and long-term LEA outcomes and its therapeutic implications need further investigation.
