Abstract Background: Total lymphocyte count (TLC) has been shown to correlate with outcomes in patients (pts) with acute leukemia. The clinical correlation to TLC in pts with chronic myeloid leukemia in chronic phase (CML-CP) who were treated with a tyrosine-kinase inhibitor (TKI) is unclear. Methods: Lymphocyte data in pts with newly diagnosed CML-CP who were enrolled in consecutive or parallel clinical trials with front-line imatinib (IM), nilotinib (Nilo), or dasatinib (Dasa) were collected at the time of diagnosis, and 3 and 6 months (M) after the start of TKI. Relative lymphocytrosis (RLC) was defined as lymphocyte >150% at 3 or 6M compared with baseline at diagnosis. Absolute lymphocytosis (ALC) was defined as lymphocyte > 4,000 /µL at 3 or 6M after the start of TKI. Pts were assessed for response, overall survival (OS), event-free survival (EFS), transformation-free survival (TFS), and failure-free survival (FFS) based on ALC and RLC. The Kaplan-Meier method was used to calculate OS, EFS, TFS, and FFS. A log-rank test and Cox regression were used for univariate (UVA) and multivariate analysis (MVA), respectively. Results: A total of 483 pts were enrolled in this study: 271 in IM, 105 in Nilo, and 107 in Dasa. Patient characteristics and outcomes are summarized in Table 1. Median age at diagnosis was 48 years, and median follow-up was 85M and ongoing (5-154+). Time from diagnosis to start of TKI, Sokal risk score, and ALC at baseline between groups did not differ clinically. Of 481 pts, 93 (19%) developed RLC at 3 or 6M; IM, 38 (14%); Nilo, 23 (22%); Dasa, 32 (30%) (p= .001). ALC at 3 or 6M was observed in 15 (3%); IM, 3 (1%); Nilo, 1 (1%); Dasa, 11 (10%) (p<.001). Overall, cumulative incidence of complete cytogenetic response (CCyR) at 6M, major molecular response (MMR) at 12M, molecular response with 4.5 log reduction by IS (MR4.5) at 24M did not differ significantly between RLC and non-RLC (3 or 6M), or between ALC and non-ALC (3 or 6M). 5-y TFS, EFS and OS in ALC group were significantly worse than those in non-ALC group (p= .002, p=.016, p=.008, respectively). By UVA and MVA related to OS, age [p <.001; Hazard ratio (HR), 1.062; 95% confidence interval (95%CI), 1.036-1.089], presence of ALC at 3 or 6M [p = .028; HR, 10.948; 95%CI, 1.297-92.415], absence of MMR at 24M [p=.016; HR, 2.263; 95%CI, 1.165-4.393] were identified as adverse prognostic factors for OS. Conclusion: The presence of ALC ≥4,000/µL at 3 or 6M of TKI therapies is rare but is adversely associated with overall survival. Table 1.

Abstract Introduction: Evidence establishes that COVID-19 patients with DM2 are at increased risk for severe disease and worse outcomes. Peer reviewed data is sparse comparing glycemic control and clinical outcomes among COVID-19 patients with vs. without DM2, and thus we sought to address this gap. Methods: We selected patients at least 18 years old who expired or were discharged between March 16, 2020 through September 15, 2020. Principal analysis compared glycemic patterns among patients with DM2 vs. non-DM2. Median, coefficient of variation (CV), maximum and minimum glucose parameters were computed to characterize longitudinal glycemic patterns. Logistic regression modeling identified significant (p&lt;.05) associations between composite outcome vs. glycemic parameters and putative risks for progression to severe COVID-19. Receiver operating characteristic (ROC) curve identified cut points for glycemic parameters. Cox regression models were employed to control for significant confounders. Continuous data summarized as median was compared using Kruskal-Wallis test. Discrete data were compared with Pearson’s chi-square test. Two-tailed p&lt;.05 was significant. Results: Among 494 patients, 157 (32%) had DM2 with no intergroup differences in age (68 [56–79]), sex (52% male, 48% female), or race (68% Caucasian, 19% Other, 13% African American). Insulin was administered to DM2 (93%) and non-DM2 (54%) patients (p&lt;.0001). Comorbidities were more prevalent in DM2, including cardiovascular (68% vs. 54%, p=.003), renal (72% vs. 52%, p&lt;.0001) and obesity (51% vs. 38%, p&lt;.0001). Markers including D-dimer (0.98 [0.61–1.95] mg/L), lactate dehydrogenase (308 [230–392] U/L), ferritin (436 [174–856] ng/mL), and triglycerides (172 [109–239] mg/dL), were not different in DM2 vs. non-DM2 (p&gt;.05). CRP was greater in patients with (8.6 [3.6–14.6]) vs. without (6.1 [2.0–12.6]) DM2 (p=.005). Baseline glucose in DM2 (163 [121–253] mg/dL) vs. non-DM2 (107 [96–124] mg/dL) was significantly greater, with former an independent predictor of composite outcome (p=.0005). Cox modeling of other glucose parameters in DM2 vs. non-DM2 demonstrated various impact regarding risk for composite outcome including median (155 [128–209], p=.46) vs. (103 [94–118], p=.09); coefficient of variation (28 [19–38], p=.08) vs. (15 [9–20], p=.002); maximum (252 [187–362], p=.0005) vs. (129 [110–156], p=.002); and minimum (99 [79–128], p=.95) vs. (89 [81–98], p=.02). The unified baseline glucose cut point for composite outcome risk controlled for significant covariates was 138 gm/dL (p&lt;.0001), which included respectively 20% and 10% of patients with and without DM2. Conclusion: Glycemic dysregulation in COVID-19 patients is independently associated with ICU admission and/or hospital mortality. Presence of DM2 amplifies glycemic dysregulation, but risk stratification appears warranted in all COVID-19 patients.

ObjectiveTo evaluate the cost–utility of 100 days of antibiotics in patients with chronic low back pain (LBP) and type I or II Modic changes included in the Antibiotic treatment In patients with chronic low back pain and Modic changes (AIM) study.DesignA cost–utility analysis from a societal and healthcare perspective alongside a double-blinded, parallel group, placebo, multicentre trial.SettingHospital outpatient clinics at six hospitals in Norway. The main results from the AIM study showed a small effect in back-related disability in favour of the antibiotics group, and slightly larger in those with type I Modic changes, but this effect was below the pre-defined threshold for clinically relevant effect.Participants180 patients with chronic LBP, previous disc herniation and Modic changes type I (n=118) or type II (n=62) were randomised to antibiotic treatment (n=89) or placebo-control (n=91).InterventionsOral treatment with either 750 mg amoxicillin or placebo three times daily for 100 days.Main outcome measuresQuality-adjusted life years (QALYs) by EuroQoL-5D over 12 months and costs for healthcare and productivity loss measured in Euro (€1=NOK 10), in the intention-to-treat population. Cost–utility was expressed in incremental cost-effectiveness ratio (ICER).ResultsMean (SD) total cost was €21 046 (20 105) in the amoxicillin group and €19 076 (19 356) in the placebo group, mean difference €1970 (95% CI; −3835 to 7774). Cost per QALY gained was €24 625. In those with type I Modic changes, the amoxicillin group had higher healthcare consumption than the placebo group, resulting in €39 425 per QALY gained. Given these ICERs and a willingness-to-pay threshold of €27 500 (NOK 275 000), the probability of amoxicillin being cost-effective was 51%. Even when the willingness-to-pay threshold increased to €55 000, the probability of amoxicillin being cost-effective was never higher than 53%.ConclusionsAmoxicillin treatment showed no evidence of being cost-effective for people with chronic LBP and Modic changes during 1-year follow-up.Trial registration numberClinicalTrials.gov NCT02323412.

Abstract Most children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have mild or minimal disease, with a small proportion developing severe disease or multisystem inflammatory syndrome in children (MIS-C). Complement-mediated thrombotic microangiopathy (TMA) has been associated with SARS-CoV-2 infection in adults but has not been studied in the pediatric population. We hypothesized that complement activation plays an important role in SARS-CoV-2 infection in children and sought to understand if TMA was present in these patients. We enrolled 50 hospitalized pediatric patients with acute SARS-CoV-2 infection (n = 21, minimal coronavirus disease 2019 [COVID-19]; n = 11, severe COVID-19) or MIS-C (n = 18). As a biomarker of complement activation and TMA, soluble C5b9 (sC5b9, normal 247 ng/mL) was measured in plasma, and elevations were found in patients with minimal disease (median, 392 ng/mL; interquartile range [IQR], 244-622 ng/mL), severe disease (median, 646 ng/mL; IQR, 203-728 ng/mL), and MIS-C (median, 630 ng/mL; IQR, 359-932 ng/mL) compared with 26 healthy control subjects (median, 57 ng/mL; IQR, 9-163 ng/mL; P &lt; .001). Higher sC5b9 levels were associated with higher serum creatinine (P = .01) but not age. Of the 19 patients for whom complete clinical criteria were available, 17 (89%) met criteria for TMA. A high proportion of tested children with SARS-CoV-2 infection had evidence of complement activation and met clinical and diagnostic criteria for TMA. Future studies are needed to determine if hospitalized children with SARS-CoV-2 should be screened for TMA, if TMA-directed management is helpful, and if there are any short- or long-term clinical consequences of complement activation and endothelial damage in children with COVID-19 or MIS-C.

There is some evidence that male gender could have a negative impact on the prognosis and severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The aim of the present study was to compare the characteristics of coronavirus disease 2019 (COVID-19) between hospitalized men and women with confirmed SARS-CoV-2 infection. This multicenter, retrospective, observational study is based on the SEMI-COVID-19 Registry. We analyzed the differences between men and women for a wide variety of demographic, clinical, and treatment variables, and the sex distribution of the reported COVID-19 deaths, as well as intensive care unit (ICU) admission by age subgroups. This work analyzed 12,063 patients (56.8% men). The women in our study were older than the men, on average (67.9 vs. 65.7 years; p < 001). Bilateral condensation was more frequent among men than women (31.8% vs. 29.9%; p = 0.007). The men needed non-invasive and invasive mechanical ventilation more frequently (5.6% vs. 3.6%, p < 0.001, and 7.9% vs. 4.8%, p < 0.001, respectively). The most prevalent complication was acute respiratory distress syndrome, with severe cases in 19.9% of men (p < 0.001). In men, intensive care unit admission was more frequent (10% vs. 6.1%; p < 0.001) and the mortality rate was higher (23.1% vs. 18.9%; p < 0.001). Regarding mortality, the differences by gender were statistically significant in the age groups from 55 years to 89 years of age. A multivariate analysis showed that female sex was significantly and independently associated with a lower risk of mortality in our study. Male sex appears to be related to worse progress in COVID-19 patients and is an independent prognostic factor for mortality. In order to fully understand its prognostic impact, other factors associated with sex must be considered.

Background:BAFF, APRIL and BAFFR are genes that encode cytokines with a key role in the development and survival of B-lymphocytes [1-4]: The B cell-activating factor (BAFF, also known as BLyS), a proliferation-inducing ligand (APRIL) and BAFF receptor (BAFF-R), respectively. Previous genetic studies have revealed that the BAFF-APRIL-BAFFR pathway is implicated in the genetic predisposition to several immune-mediated diseases [5].Objectives:To determine whether the BAFF-APRIL-BAFFR pathway represents a novel genetic risk factor for the pathogenesis of Immunoglobulin-A vasculitis (IgAV), an inflammatory disease in which IgA deposits and B-lymphocytes are crucial [6, 7].Methods:A functional BAFF polymorphism (rs374039502) and two tag variants within APRIL (rs11552708 and rs6608) and BAFFR (rs7290134 and rs77874543) were genotyped in 386 Caucasian IgAV patients (the largest series of Caucasian patients with IgAV ever assessed for genetic studies) and 806 sex and ethnically matched healthy controls by TaqMan assays.Results:No statistically significant differences in the genotype and allele frequencies between patients with IgAV and healthy controls were observed when each genetic variant of BAFF APRIL and BAFFR was analyzed independently (Table 1). Likewise, no statistically significant differences in genotype and allele frequencies of BAFF APRIL or BAFFR were found when patients with IgAV were stratified according to the age at disease onset or to the presence/absence of gastrointestinal or renal manifestations. Similar results were disclosed when haplotype frequencies of APRIL and BAFFR were compared between patients with IgAV and healthy controls as well as patients with IgAV stratified according to the age at disease onset or to the presence/absence of gastrointestinal or renal manifestations.Conclusion:Our results suggest that the BAFF-APRIL-BAFFR pathway does not contribute to the genetic network underlying IgAV.References:[1]J Exp Med 1999;190:1697-710; [2] Science 1999;285:260-3; [3] Nat Genet 2005;37:829-34; [4] Nat Immunol 2002;3:822-9; [5] N Engl J Med 2017;376:1615-26; [6] N Engl J Med 2013;368:2402-14; [7] Autoimmun Rev 2018;17:301-315.Table 1.Genotype and allele frequencies of BAFF, APRIL and BAFFR genes in patients with IgA vasculitis and healthy controls.PolymorphismLocus1/2Data set1/11/22/212rs374039502BAFFT/APatients91.9 (353)8.1 (31)095.9 (737)4.1 (31)Controls91.5 (733)8.1 (65)0.4 (3)95.6 (1531)4.4 (71)rs11552708APRILG/APatients78.1 (299)20.6 (79)1.3 (5)88.4 (677)11.6 (89)Controls77.9 (625)20.4 (1641.6 (13)88.1 (1414)11.9 (190)rs6608APRILC/TPatients71.9 (277)26.0 (100)2.1 (8)84.9 (654)15.1 (116)Controls70.0 (561)27.6 (221)2.5 (20)83.7 (1343)16.3 (261)rs7290134BAFFRA/GPatients58.0 (224)36.3 (140)5.7 (22)76.2 (588)23.8 (184)Controls57.2 (459)36.4 (292)6.5 (52)75.3 (1210)24.6 (396)rs77874543BAFFRG/CPatients82.7 (316)16.0 (61)1.3 (5)90.7 (693)9.3 (71)Controls83.0 (666)16.6 (133)0.4 (3)91.3 (1465)8.7 (139)Acknowledgements:This study was supported by European Union FEDER funds and “Fondo de Investigaciones Sanitarias” (grant PI18/00042) from ‘Instituto de Salud Carlos III’ (ISCIII, Health Ministry, Spain).

Background There have been well-documented implications of race/ethnicity on the outcome of various vascular diseases. Little literature has examined the effect of race/ethnicity on venous disease. Iliac vein stenting is an emerging technology in treating chronic venous insufficiency. To further characterize this disease and its treatment, we chose to study the effect of selected clinical factors including race/ethnicity on the early complications of non-thrombotic iliac vein stenting. Methods In this observational study, data analysis was performed for 623 patients with chronic venous insufficiency who underwent iliac vein stenting during the time period from August 2012 to September 2014. Patients were categorized by Caucasians ( n = 396), African Americans ( n = 89), Hispanics ( n = 138), and others ( n = 23). These were correlated with the age, gender, presenting sign according to CEAP classification, percentage of iliac vein stenosis, post-operative thrombosis and pain score. Pain score was obtained post-operatively on a Likert scale of 0–10. Follow-up was performed after completion of the procedure, through post-operative visits and duplex exams every three months for the first year. Statistical analysis was performed using Chi-square and Student’s t-test, Pearson’s test and multivariate regression. Results The average age of the study patients was 67.8 years (age range 23–96 years, ± 14.2 SD). Sixty-seven patients were women. The presenting sign according to CEAP classification was (C3 = 331, C4 = 175, C5 = 51, C6 = 66). The average pain score was 2.6 (±2.9 SD). The average degree of stenosis was 64.9% (±3.8 SD). There were insufficient numbers in the “other” race/ethnicity group for further analysis. The number of patients with iliac vein stent thrombosis was 14 (2.2%). When analyzing each race/ethnicity in our dataset with univariate analysis, we found that Caucasians were significantly older than the African Americans and Hispanics ( P < 0.0001). There tended to be more women in the Caucasian group as compared to the Hispanics ( P = 0.04). There were no differences in presenting sign according to CEAP classification or degree of stenosis between the three groups. Hispanics tended to have higher pain scores post-operatively than Caucasians ( P = 0.01). It was found that 1.8% of Caucasians, 3.4% of African Americans and 2.9% of Hispanics had post-operative iliac vein stent thrombosis ( P = 0.55). Men have higher CEAP score than women regardless of race/ethnicity ( P = 0.0001). On the other hand, women tended to have higher pain score than men ( P = 0.04). There were no differences between men and women regarding age, degree of stenosis, and stent thrombosis. Linear multivariate regression test and Pearson’s test revealed that age is inversely related to pain score ( P < 0.0001). ANOVA multivariate regression statistical analysis showed no relation between race/ethnicity and pain score ( P = 0.98), and one-way ANOVA showed that the Caucasians were the eldest ethnic group in the study ( P < 0.0001). Linear multivariate regression test and Pearson’s correlation test revealed that race/ethnicity is not correlated with thrombosis of iliac vein after stenting ( P = 0.8). Conclusion Race/ethnicity is not significantly associated with CEAP score, degree of iliac vein stenosis, or post-operative thrombosis or pain scores. Age was inversely associated with pain score after iliac vein stenting.

Background:Cardiovascular (CVS) diseases are the leading cause of death worldwide and patients with rheumatic diseases have an increased CVS risk including stroke and myocardial infarction (MI) (1-3). CVS risk factors and CVS events are common in SpA (4). Delineating the CVS risk and the association with medications in patients with SpA would be useful.Objectives:The objective of this study was to delineate the CVS risk and the association with medications in patients with SpA.Methods:Patients with SpA and patients with non-specific back pain (NSBP) were identified in rheumatology and orthopedics clinics respectively. Clinical information and CVS events were retrieved. Incidence rates were calculated. Association analysis was performed to determine the CVS risk of SpA and other modifiable risk factors.Results:A total of 5046 patients (SpA 2616 and NSBP 2430) were included from eight centers. Over 56 484 person-years of follow-up, 160 strokes, 84 MI and 262 major adverse cardiovascular events (MACE) were identified. Hypercholesterolemia was more prevalent in SpA (SpA 34.2%, NSBP 28.7%, P<0.01). Crude incidence rates of stroke and MI were higher in SpA patients. SpA was associated with a higher risk of MACE (HR 1.66, 95%CI 1.22-2.27, P<0.01) and cerebrovascular events (HR 1.42, 95%CI 1.01-2.00, p=0.04). The use of anti-tumor necrosis factor (TNF) drugs was associated with a reduced risk of MACE (HR 0.37, 95%CI 0.17-0.80, P=0.01) and cerebrovascular events (HR 0.21, 95%CI 0.06-0.78, P=0.02).Conclusion:SpA is an independent CVS risk factor. Anti-TNF drugs were associated with a reduced CVS risk in these patients.References:[1]Crowson CS, Liao KP, Davis JM, 3rd, Solomon DH, Matteson EL, Knutson KL, et al.

Abstract Background: To describe the clinical characteristics (CC) and survival predictors in NHL pts at a VA medical center. Methods: We performed a retrospective chart review of all pts diagnosed with Non Hodgkin’s lymphoma at the VANJHCS from January 1, 1997 through December 31, 2006. Records were reviewed for demographic, clinical, pathological data and survival. Statistical analyses were performed using STATA. The study was approved by the IRB. Results: 1. Clinical characteristics. There were 92 pts, with 57 deaths(62%). The median (M) age was 62 years (range 27–89). The race distribution was Caucasian 66(72.5%), African American 19(21%), other (6, 6.5%). The overall M survival (MS) was 698 days(13–3825). The M Hemoglobin(Hgb) was 12.3 g/dl (7.3–17.4) The M LDH was 203 IU/L(88–1905). The M Albumin was 3.6 g/dl (1.2–5.4). Beta 2 microglobulin (B2M) and HIV status were not available on all patients. The M Zubrod Performance Status (PS) was 1(0–4). The PS for 46 pts (50%) was 1(0–4). By Ann Arbor Stage, 44 pts(49%) were in stage I–II, and 46 pts(51%) had stages III–IV. MS for pts in stage I–II were 887.5(range 13–3713) days and 552(range 22–3825) days in stages III–IV. 2. Survival by histology is summarized in the accompanying table. Histological categories were low grade (CLL, follicular, MALT, marginal zone), diffuse large cell lymphoma, mantle cell lymphoma (MCL) and other(2 pts). The most common class of pts was low grade 49(53%), followed by intermediate 34(36.9%) and mantle cell lymphoma 9(9.7%). 3. Clinical Prognostic indicators: Charlson Comorbidity Index (CMI), the International Prognostic Index (IPI) and the Follicular Lymphoma International Prognostic Index (FLIPI) scores were tabulated. For pts with intermediate lymphoma, the M IPI score was 3 (range 0–5), and for low grade lymphoma M IPI score 2 (0–5). The 47 pts with low grade lymphomas had median FLIPI score of 1 (0–4). The M CMI was 6(1–12). 4. For all pts, univariate predictors of survival were lymphoma class, hemoglobin, PS, LDH, albumin. The IPI was a significant predictor on univariate analysis. In multivariate analysis, the PS(p<0.02), Albumin (p<0.02), CMI (p<0.05), LDH (p<0.06) and lymphoma class (p<0.02) were significant predictors. For low grade lymphoma pts, univariate predictors were LDH, albumin, IPI, and PS, but not the FLIPI. On multivariate analysis, the predictors were PS (p<0.02), and albumin (p<0.018). For intermediate grade lymphoma pts, univariate predictors were albumin, but not the IPI. On multivariate analysis, the PS (p<.006), albumin (p<0.03), and CMI (p<.02) were significant predictors. Conclusions: In this sample, prognostic factors differed for low grade and intermediate grade lymphomas. IPI did not predict survival in intermediate lymphoma pts. Comorbidity emerged as a potential prognostic factor for pts with intermediate grade lymphomas. The VA provides care for a large veteran population characterized by low socioeconomic status and higher comorbidity. These findings should be confirmed in larger VA and general populations. Survival by Histology Lymphoma type Number of pts Median survival(days) Range(days) Diffuse large 32(37%) 466 17–3402 CLL 14(15%) 1711 25–3541 Follicular 19(20%) 943 13–3825 Mantle cell 9(10%) 748 62–1231 Marginal zone 8(9%) 627 197–2686 MALT 8(9%) 1311 393–3194

Abstract Introduction: MCL is a mature B-cell neoplasm characterized by t(11;14) (q13;q32) and cyclin D1 (CCND1) overexpression. Molecular studies have revealed other alterations in cell-cycle regulation, DNA damage response and cell survival pathways, with a landscape of somatic mutations being recently identified. CNS involvement is a well known complication, occurring in 4-26% of MCL at five years, with an ominous significance. Although different clinical variables have been identified as risk factors for CNS infiltration, the biological parameters related to this complication have not been extensively studied. The aim of the study was to explore the biological parameters associated with CNS involvement in a multicentre and retrospective series of MCL patients. Patients and Methods: 285 patients (M:74%; 64 yr) diagnosed of MCL between 1990-2014 (median survival of 4 years) were analysed. In addition to standard clinico-biological variables, IGHV mutational analysis, chromosomal alteration studies and Sanger sequencing of NOTCH1, NOTCH2, TP53, BIRC3, WHSC1, MEF2B, MLL2, TLR2 and PRDM1 were performed. Results: CNS involvement was observed in 15/285 MCL patients (5.2%), with a 5-yr risk of 9.1% (95%CI: 4.6-13.6), one patient at diagnosis, and at first or second/ulterior progressions in 7 cases each. The clinical, pathological and molecular risk factors identified are detailed in the Table. In addition to what has been already described, CNS involvement was usually observed in MCL cases with a clinical nodal presentation (p=0.05). In fact, no indolent MCL with a non-nodal presentation developed this complication during the follow-up period. No differences were observed in the risk of CNS involvement between patients treated in first-line with conventional or high-dose intense treatment (5-yr risk: 6.1%+/-6% vs. 10.7%+/-10.6%, p=ns). Regarding the biological features, no differences in terms of the IGHV mutational status were observed in cases developing CNS involvement compared to the others (75% vs. 68.7%, using 97% identity cut-off). Similarly, the IGHV gene usage of CNS involved cases corresponded to the more frequent IGHV genes observed in MCL (usually IGHV1-18, IGHV3-23, IGHV4-34, IGHV4-59). Although not significant, a predominance of high number copy number alterations (CNA) (>4) could be observed in the genetic study of MCL cases with CNS involvement as could be expected for the enrichment in blastoid variants (up to 50% of these cases). In fact, we did not observe any case with CNS involvement among those cases with 3 or less CNA. CNS involvement was not related to common poor prognosis genetic alterations such as 9p, 11p and 17p losses, but the presence of 8q gains was associated with a higher risk of CNS involvement (p=0.05). We did not find any significant association between CNS involvement and the large number of oncogenic mutations studied. Conclusions: CNS involvement in MCL is associated with initial aggressive clinico-biological characteristics. Non-nodal MCL cases with a low number of genetic alterations did not present CNS involvement. Finally, the presence of 8q gains was associated with a higher risk of CNS infiltration.

Background:Juvenile systemic sclerosis (jSSc) is a rare disease with a prevalence of around 3 in 1,000,000 children. To better capture the clinical manifestations of jSSc the juvenile systemic sclerosis inception cohort (jSScC) has been prospectively enrolling patients with predetermined clinical variables over the past 12 years. One of the goals is to study the demographic, clinical features, and physician and patient reported outcome differences between those with juvenile limited cutaneous (lc) compared to diffuse cutaneous (dc) disease subtypes, to determine if characteristics are similar or different between dc and lc jSSc.Objectives:Evaluation of the baseline clinical characteristics of jSSc patients in the jSScC. Compare clinical phenotype between diffuse (dcjSSc) and limited cutaneous (lcjSSc) subtypes.Methods:Demographic, physical examination, organ system evaluation, autoantibody profile, treatment, and patient and physician reported outcome variables were evaluated from the jSSc Inception cohort and summary statistics applied using chi-square test and Mann Whitney U-test comparing lcjSSc and dcjSSc subtypes.Results:At the time of data extraction, 175 jSSc patients were enrolled in the cohort, 81% were Caucasian and 81% female. Diffuse cutaneous jSSc subtype predominated (73%). Mean disease duration was 3.1 year (±2.7). Mean age at Raynaud´s was 10 years (+3.8) and mean age of first non-Raynaud´s was 10.2 years (±3.8). Significant differences were found between dcjSSc versus lcjSSc, regarding several clinical characteristics. Patients with diffuse cutaneous subtype had significantly higher modified Rodnan skin score (p=0.001), presence of sclerodactyly (p=0.02), presence of Gottron’s papules (p=0.003), presence of telangiectasia (p=0.001), history of digital tip ulceration (p=0.01), and frequency of elevated CK value (p=0.04). Cardiac involvement was significantly higher in limited cutaneous jSSc subtype (p=0.02). Diffuse cutaneous jSSc patients had significantly worse scores for Physician Global Assessment of disease activity (38 vs 25; p=0.002) and disease damage (34 vs 19; p=0.008).Table 1.Comparison of demographic data and significant differences between dcjSSc and lcjSSc at time of inclusionWhole CohortN=175Diffuse SubtypeN=128Limited SubtypeN=47P valueFemale to Male Ratio4.3:1 (142/33)4.1:1 (103/25)4.8:1 (39/8)0.829Cutaneous subtypeDiffuse subtype73% (128)1280Limited subtype27% (47)047Mean Disease duration (years)3.1 (± 2.7)3.3 (± 2.9)2.6 (± 2.2)0.135Mean age of onset of Raynaud´s (years)10.0 (± 3.8)17 non-Raynaud9.8 (± 3.6)10 non-Raynaud10.6 (± 4.3)7 non-Raynaud0.219Mean age of onset of non-Raynaud´s (years)10.2 (± 3.9)10.0 (± 3.7)10.9 (± 4.3)0.173Disease modifying drugs88% (154)89% (114)85% (40)0.446CutaneousMean modified Rodnan skin score14.3 (0-51)17.4 (0-51)6.1 (0-24)0.001Gottron Papules27% (46/171)33% (41/124)11% (5)0.003Sclerodactyly78% (126/162)82% (98/119)65% (28/43)0.020Laboratory valuesElevated CK25% (30/122)30% (26/88)12% (4/34)0.041VascularTelangiectasia36% (56/154)44% (49/111)16% (7/43)0.001History of ulceration53% (91/173)61% (77/127)30% (14/46)0.001CardiacCardiac Involvement6% (10)2% (3)15% (7)0.002Patient Related OutcomesPhysician global disease activity(0-100) min -max35(0-90) n=14138(0-90) n=10825(0-80) n=330.002Physician global disease damage(0-100) min -max31(0-85) n=14034(0-85) n=10819(0-60) n=320.008Conclusion:Results from this large international cohort of jSSc patients demonstrate significant differences between dcjSSc and lcjSSc patients.

Abstract Abstract 3538 Poster Board III-475 Introduction Recently, Yttrium-90 labeled anti-CD20 (90Y-ibritumomab tiuxetan, Zevalin®) has been introduced as a new therapeutic option in relapsed malignant B cell lymphoma. The results of adding 90Y-ibritumomab tiuxetan to high-dose BEAM with autologous stem-cell transplantation(auSCT) are promising. However, the toxic impact of radioimmunotherapy to the haematopoietic microenvironment, and its effects on stem cell homing and engraftment are largely unknown. Stromal Derived Factor-1 (SDF-1α) is a key regulator of stem cell engraftment. SDF-1α has been found to co-localize with hyaluronan (HA) on human bone marrow sinusoidal endothelium and endosteum, supporting transendothelial migration of human progenitor cells and their final anchorage within specific niches of the BM. External irradiation influences levels of SDF-1α and HA. Therefore, we studied the effect of 90Y-ibritumomab tiuxetan on in vivo SDF-1α and HA levels. Patients and methods Patients with relapsed B cell NHL, treated with Zevalin-BEAM and autologous stem cell transplantation were included after obtaining their informed consent. At 3 different time points, bone marrow aspirates and peripheral blood samples of 9 consecutive patients were analysed: day -22 (before Z-BEAM), day -8 (7 days after Zevalin (0.4 mCi/kg, max. 32 mCi (n=8) or 64 mCi (n=1) (before BEAM)) and day 0 (after BEAM and before auSCT). SDF-1α and HA protein levels were determined in bone marrow and peripheral blood plasma using ELISA. Also, SDF-1α mRNA expression was quantified by real time PCR. Quality of bone marrow stroma was determined by investigating CFU-F after 1 and 2 weeks and the percentage of confluency in cultures after 1, 2 and 3 weeks. Also, in 5 patients dosimetry of Zevalin was performed. Results In 5 patients dosimetry of Zevalin was performed, by using Zirconium-89 labelled Zevalin as surrogate for PET scanning at day 0, +3 and +6 after injection. Patients received 3.4.10 * 6/kg(mean, range 1,9-8,3) CD34+ cells, and all but one showed engraftment. ANC>0.5 10*9/l was reached at 12,8 days (range 11-15, n=9), platelets>50 10*9/l at 18 days (range 11-38, n=8) ), being comparable with retrospective data on BEAM transplantation. In the one patient not recovering, a second transplant did not result in platelet recovery. Zevalin alone did not affect bone marrow MNC count (23,3 vs 17,4 10*6/ml, p=0.40), CFU-F capacity (colonies > 50 cells: 2,4 vs 8,3, p=0.35) and stromal confluency (41,9 vs 62,1%, p=0.31). In addition, the levels of SDF-1α (4584 vs 5305 pg/ml, p=0.11) and HA (227 vs 247 mcg/ml, p=0.86) were not influenced. Following BEAM, production of SDF-1α (4584 vs 6166 pg/ml, p=0.01) and HA levels (227 vs 356 mcg/ml, p=0.03), significantly increased. A corresponding increase in SDF-1α mRNA copies was observed (0.16 vs 17.2 cps % GAPDH, p=0.02), indicating that induction of SDF-1α gene expression was involved. There was a trend in decreased quality of bone marrow stroma, as determined by MNC count, CFU-F capacity and confluency. Whereas Fibroblast Growth Factor increased the confluence of stromal culture before and after Zevalin, it didn't overcome the harmful effect of the BEAM chemotherapy. Conclusion 90Y-ibritumomab tiuxetan alone did not effect the bone marrow environment as measured by SDF-1α and HA. As expected, significant changes were found after high dose chemotherapy. Engraftment and repopulation after Z-BEAM and auSCT was similar to standard BEAM followed by auSCT. Disclosures: No relevant conflicts of interest to declare.

Abstract Background The median survival (OS) of patients with primary myelofibrosis (PMF; 6.5y) is significantly shortened compared to reference population (Cervantes et al, JCO 2012; 30:2981). OS is predicted by the four risk categories of IPSS, Dynamic-IPSS and DIPSS-plus score, nevertheless pts heterogeneity persists within these categories, necessitating improved risk stratification. We recently reported that pts harboring mutations in any one of the prognostically relevant ASXL1, EZH2, IDH1/2 and SRSF2 genes constitute a IPSS-and DIPPS-plus independent Molecular High Risk category (MHR+) characterized by significant reduction of OS and leukemia free survival (LFS) (Vannucchi et al, Leukemia 2013). The aim of this work was to analyze the impact of the number of prognostically relevant mutated genes on OS and LFS in PMF. Patients and methods Two independent cohorts are included, a “test cohort” from Europe, analyzed at diagnosis, and a “validation cohort” from Mayo Clinic, analyzed at any time after diagnosis. Mutation analysis was performed in DNA from whole blood or granulocytes using RTQ-PCR, HRM and direct sequencing; all mutations were confirmed at least twice. The prognostic value of the molecular variables with regard to OS and LFS was analyzed by Cox regression. Test cohort It included 490 pts (median age 61y; males = 301) risk stratified by IPSS into high (n=74, 15%), intermediate-2 (n=93, 19% ), intermediate-1 (n=147, 30%) and low (n=176, 36%). The median follow-up was 3.63y (95% CI, 0.06-28.33); 161 pts died (33.0%), of whom 76 (15.6%) had progressed to acute leukemia after a median of 3.4y (0.04-28.3) from diagnosis. One hundred forty-six pts (29.8%) presented at least one of the four aforementioned mutated genes and were classified as MHR+. The OS of MHR+ pts was significantly reduced compared to patients with no mutations (n=344): 80.7 vs 148.9 mo (HR 2.2, CI95% 1.6-3.03). One hundred twelve (22.8%) pts had 1 mutation and 34 (6.9%) had 2 or more mutations. In univariate analysis presence of 2 or more mutated genes was significantly more detrimental for OS (29.5mo; HR 4.12, IC95% 2.6-6.4) than having 1 mutated gene (84.2mo; HR 1.8, IC95% 1.2-2.5) compared with having no mutations (148.9mo). Multivariate analysis results adjusted for IPSS indicated that having two or more mutations was an independent prognostic factor for OS (HR 2.9, 95% CI 1.8-4.5). Notably, the prognostic relevance of harboring two or more mutations involved both lower (low and intermediate-1; HR 1.87, 95% CI 1.3-2.6) and higher (intermediate-2 and high; HR 1.6, 95% CI 1.2-2.1) categories of IPSS. Also LFS resulted significantly shorter (129mo; HR 3.1, 95%CI 1.9-4.8) in MHR+ pts compared with pts with no adverse mutations (323mo). Having 2 or more mutations correlated with greater reduction of LFS (79.6mo; HR 7.02, CI95% 3.9-12.6) than having one mutation only (133.9mo; HR 2.2, IC95% 1.3-3.7) as compared with no mutations (323.2mo). Multivariate analysis showed that IPSS high risk category (HR 4.5; 95% CI 2.3-8.8) and two or more mutated genes (HR 5.3; 95% CI 2.9-9.8) predicted independently for a significant reduction in LFS. The negative impact on LFS of having 2 or more mutated genes compared to one or no mutations was maintained in the lower (HR 6.4, 95% CI 2.6-15.2) and higher (HR 5.5, 95% CI 2.3-12.8) risk categories. Validation cohort Validation cohort included 262 patients (median age 64 years; males = 167) risk stratified by DIPSS-plus into high (n=89, 34%), intermediate-2 (n=92, 35%), intermediate-1 (n=46, 18%) and low (n=34, 13%). One hundred forty-six pts (56%) displayed none of the four aforementioned mutations, 93 (36%) harbored one mutation whereas 23 (9%) harbored two or more mutations. In univariate analysis, having two or more mutations (HR 3.7; 95% CI 2.2-6.1) was significantly more detrimental for OS than having no mutations, which is more favorable than having one mutation (HR 1.9; 95% CI 1.4-2.7). When adjusted for DIPSS-plus, the presence of two or more mutations retained its significance (HR 2.1; 95% CI 1.3-3.6) and outperformed ASXL1 mutation alone in its prognostic relevance Conclusions Overall, these results show that the number of prognostically relevant mutated genes correlate with OS and LFS in pts with PMF, suggesting that screening for these mutations might help to improve risk stratification.

Эндофуллерены, содержащие один или несколько атомов металла внутри углеродного каркаса (металлофуллерены), представляют большой практический интерес в связи с возможностью создания на их основе эффективных контрастирующих агентов для магнитно-резонансной томографии (МРТ), антиоксидантных и противораковых средств. Данные соединения могут быть также использованы в спинтронике для создания наноразмерных электронных устройств. В настоящей работе в рамках теории функционала плотности произведен расчет структурных, электронных и термодинамических характеристик эндофуллеренов металлов подгруппы скандия с числом инкапсулированных атомов от одного до семи в газовой фазе. Описаны стабильные структуры с симметриямиCs, C2, C3 и Ci, соответствующие позициям, занимаемым атомами металла внутри каркаса фуллерена. Установлен теоретический предел числа атомов металла, при котором структура эндофуллерена сохраняет устойчивость – шесть атомов для скандия, четыре для иттрия и три для лантана. Расчет показывает, что наиболее устойчивыми являются структуры с двумя и тремя инкапсулированными атомами. Описана зависимость между числом инкапсулированных атомов металла и характером распределения электронной плотности. Общий заряд на инкапсулированном металлическом кластере положителен для соединений Me@C60 – Me3@C60, слабо положителен для Me4@C60(отдельные атомы имеют отрицательный заряд) и отрицателен для соединений Me5C60 – Me6@C60. Описан эффект спиновой утечки для структур с основным дублетным спиновым состоянием. Для соединений с тремя и более инкапсулированными атомами данный эффект незначителен, что указывает на нецелесообразность создания контрастирующих агентов для МРТ на их основе. ЛИТЕРАТУРА 1. Kroto H.

Abstract Introduction: Patients with paroxysmal nocturnal hemoglobinuria (PNH) suffer high morbidity and mortality, however, data characterizing these patients by hemolytic status are unavailable. The objective of this analysis is to describe disease characteristics in patients with PNH by the presence of hemolysis. Methods: The International PNH Registry is a prospective, observational study of patients with a PNH clone of 0.01-100%. At enrollment, historic data are collected from disease start, prospectively and semi-annually thereafter. Patients enrolled on or before 8 April 2015 were eligible for this analysis and were assessed during two follow-up periods: Cohort A: follow-up time without reported hemolysis, defined as time from disease start until the last reported untreated LDH value <1.5 x upper limit normal (ULN); Cohort B: follow-up time with reported hemolysis, defined as time from LDH³ 1.5 x ULN post-disease start, to most recent untreated follow-up. Mortality and physician-reported symptoms are only assessed after enrollment in the Registry; only the subsets of Cohorts A and B untreated with eculizumab at enrollment with prospective follow-up time were eligible for analysis of these endpoints. Patients could contribute follow-up time to both cohorts. Demographics and disease characteristics were assessed and compared using the chi-square test or Fisher's exact test. Results: A total of n=1,012 patients in Cohort A and n=1,565 patients in Cohort B met the criteria for inclusion; n=191 patients contributed follow-up time to both cohorts. Median years of follow-up time (range) without hemolysis (Cohort A) and with hemolysis (Cohort B) was 2.2 (0.0, 54.2) years and 1.2 (0.0, 37.2) years, respectively. Median disease duration (disease start until last untreated follow-up) was 2.7 (0.0, 54.2) years in Cohort A vs. 5.1 (0.0, 62.9) years in Cohort B. At most recent follow-up, 69.4% of patients in Cohort A and 39.6% in Cohort B had a history of aplastic anemia. Earliest reported granulocyte clone size (median, [range]) without hemolysis (Cohort A) was 4.0% (0.01, 100) and with hemolysis (Cohort B) was 65.6% (0.01, 100.0). The annual rate of thrombotic events (TEs) was higher in Cohort B than in Cohort A (Table). A total of 676 patients in Cohort A and 1,203 patients in Cohort B were untreated at enrollment; 548 and 1,022 of these patients, respectively, had follow-up after enrollment. Median age (range) at enrollment in patients with follow-up time after enrollment was 40.0 years (7, 89) in Cohort A and 43.0 years (8, 90), in Cohort B. Over a median of 1.0 years of prospective follow-up in each cohort (range 0.0, 9.1, and 0.0,9.5), mortality was higher in Cohort B than in Cohort A (1.4% (22 deaths) vs. 0.1% (1 death); p<0.001). Physician-reported symptoms were reported in both cohorts; all except fatigue were significantly higher during hemolysis (Cohort B) (Figure). Conclusions: This real-world analysis from the International PNH Registry showed that patients with PNH had increased morbidity and mortality after reported hemolysis compared with patients without hemolysis. Thrombosis is the leading cause of mortality in patients with PNH. While the annual rate of TE was higher in hemolytic patients, the proportion of patients with TE was similar in the hemolytic and non-hemolytic cohorts. Despite similar follow-up time, mortality was higher in the hemolytic than non-hemolytic cohort. Symptoms of PNH were reported in both the hemolytic and the non-hemolytic groups; fatigue was the most frequent symptom in both cohorts, and was not statistically different between the two groups. Ongoing monitoring of the development of hemolysis in patients with PNH is important. Table 1.

Aims/Objectives/BackgroundGlobally, injuries cause more than 5 million deaths annually. Children and young people are a particularly vulnerable group and injuries are the leading cause of death in people aged 5–24 years globally and a leading cause of disability.In most low and middle-income countries where the majority of global child injury burden occurs, systems for routinely collecting injury data are limited. There is a continuing need for better data on childhood injuries and for injury surveillance.The aim of our study was to introduce a hospital-based injury surveillance tool – the first of its kind in Nepal and explore its feasibility. We undertook prospective collection of data on all injuries/trauma presenting to 2 hospital emergency departments to describe the epidemiology of paediatric hospital injury presentations and associated risk factors.Methods/DesignA new injury surveillance system for use in emergency departments in Nepal was designed and used to collect data on patients presenting with injuries. Data were collected prospectively in two hospitals 24 h a day over 12 months (April 2019 - March 2020) by trained data collectors using tablet computers.Abstract 432 Table 1Socio-demographic profile

<18 years. Most injuries in children were unintentional and over half of children presenting with injuries were <10 years of age. Falls, animal bites/stings and road traffic injuries accounted for nearly 75% of all injuries with some (drowning, poisonings and burns) under-represented. Over half of injuries were cuts, bites and open wounds. The next most common injury types were superficial injuries (14.2%); fractures (11.1%); sprains/dislocations (9.0%). Child mortality was 1%.This is the biggest prospective injury surveillance study in a low or middle country in recent years and supports the use of injury surveillance in Nepal for reducing child morbidity and mortality through improved data.CHILD PAPER: RESULTS SECTIONTotal number of ED patients: 33046Total number of ED patient with injury: 10154 (adult=7458 & children=2696)8.2% (n=2696) patients with injury were children aged <18 yearsHetauda hospital: 2274 (84.3%)Chure hill hospital: 422 (15.7%)

This paper presents a brief review on the ternary phase equilibria in the ternary AV–BVI–I systems (AV = Sb, Bi; BVI = S, Se, Te). These systems includes the series of ternary compounds those are very attractive source materials for photo-, thermos- and ferroelectric energy transformation along the recently discovered semiconductors that exhibit Rashba-type spin splitting in their surface states. In the Rashba semiconductors, a unique toroidal 3D Fermi surface appears on the crystal surface, which leads to unusual properties that make it possible to realize unique electronic devices based on these compounds. The thorough knowledge on the ternary phase diagram of these systems shed light on the chemical and structural design of new multifunctional materials with tunable properties. This knowledge is very important whenfocusing on the chemistry of such multifunctional materials based on complex element systems. REFERENCES Audzijonis A., Sereika R., Ћaltauskas R.

e4360011The objective of this research was to analyze how official documents and educational legislation present the subject of ethnic-racial diversity, and also reflect on their impact on reality through the National Household Sample Survey (PNAD) data. To this end, we conducted an analysis of legislation and official documents created for Brazilian education, from 1988 to 2018, based on the Bardin Content Analysis technique. Subsequently, this analysis was compared with the data available in the PNAD to verify the impact of publications regarding 1) average years of study by color/race in the period; 2) average years of study by color/race, considering the situation of poverty (extremely poor, vulnerable, poor and non-poor); and 3) average years of study in regions of Brazil with a higher percentage of black people. The prescriptions related to the education of ethnic-racial relations of the 12 files analyzed were described, as well as their categories and characteristics. After this process, were established the relations between the categories and the PNAD data. The results allowed us to conclude that the reduction in the average time difference between blacks and whites was a little less than 5 months. Despite the relevance of the efforts, the implementation of policies aimed at combating racial inequality in education is still far from achieving the expected effectiveness.ResumoO objetivo dessa pesquisa foi analisar como são tratadas, em documentos oficiais e na legislação educacional, as questões relativas à diversidade étnico-racial e refletir sobre o seu impacto na realidade por meio dos dados da Pesquisa Nacional por Amostra de Domicílios (PNAD). Para tanto, foi realizada uma análise das legislações e documentos oficiais criados para a educação brasileira, do período de 1988 a 2018, pautada na técnica da Análise de Conteúdo da Bardin. Subsequentemente, essa análise foi comparada com os dados disponíveis na PNAD para verificar o impacto das publicações com relação a: 1) média de anos de estudo por cor/raça, no período; 2) média de anos de estudo por cor/raça, considerando a situação de pobreza (extremamente pobres, vulneráveis, pobres e não pobres); e 3) média de anos de estudo em regiões do Brasil com percentual maior de pessoas negras. As prescrições relacionadas à educação das relações étnico-raciais dos 12 arquivos analisados foram descritas, assim como as categorias e as características que as compõem. Após esse processo, foram estabelecidas as relações entre as categorias e os dados da PNAD. Os resultados permitiram concluir que a redução da diferença de tempo médio de estudo entre brancos e negros foi de pouco menos de 5 meses. Apesar da relevância dos esforços, a implementação das políticas que visam o combate à desigualdade racial na educação ainda se apresenta longe de alcançar a eficácia esperada.Palavras-chave: Relações étnico-raciais, Legislação educacional, Desigualdades raciais, Análise de conteúdo.Keywords: Ethnic-Racial relations, Educational legislation, Racial inequalities, Content analysis.ReferencesAGUIAR, Márcia Angela Da S.

Abstract Objectives To investigate the impact of thrombocytopenia on survival in patients with APS. Methods Thrombocytopenia and other predictors of outcome were retrospectively evaluated in an aPL-positive and APS cohort with 38-year follow-up (1980–2018). Thrombocytopenia was defined as &lt;150 × 109 platelets/l. Hazard ratios (HR) of mortality were calculated using Cox-regression models. Results Among 114 patients, 64% had primary APS, 25% secondary APS and 10% asymptomatic aPL. Mean follow-up was 19 (range 5–38) years. ANA [hazard ratio (HR) 1.8, 95% CI 0.8, 3.6, P = 0.10], arterial thrombotic events (HR 7.0, 95% CI 1.4, 3.5, P = 0.016), myocardial infarction (HR 8.3, 95% CI 1.1, 59, P = 0.03), intracardiac thrombosis (HR 17, 95% CI 1, 279, P = 0.04) and thrombocytopenia (HR 2.9, 95% CI 1.4, 6.1, P = 0.004) were risk factors for all-cause mortality, but in multivariate analysis only thrombocytopenia (HR 2.7, 95% CI 1.3, 6.0, P = 0.01) remained significant. Persistent (HR 4.4, 95% CI 2.1, 9.2, P = 0.001) and low–moderate thrombocytopenia (HR 2.8, 95% CI 1.2, 6.4, P = 0.01) were associated with a significant increase in mortality compared with acute (HR 1.6, 95% CI 0.5, 5.3, P = 0.40) and severe (HR 2.1, 95% CI 0.5, 9.2, P = 0.30) forms. APS patients with vs without thrombocytopenia were more frequently male (58 vs 24%, P = 0.001) with arterial thrombosis (55 vs 32%, P = 0.04), LA positivity (100 vs 87%, P = 0.04), type I aPL profile (89% vs 71%, P = 0.05) and anticoagulant treatment (89 vs 63%, P = 0.01). Thrombosis caused 13% of deaths in thrombocytopenic patients and 1% in those without (P = 0.01). Conclusion Thrombocytopenia is an aPL-related manifestation that identifies patients with severe disease phenotype and high thrombotic risk. Persistent low–moderate thrombocytopenia is associated with a reduced long-term survival.

Introduction: Obstructive sleep apnea (OSA) is associated with cardiac dysfunction in children without congenital heart disease (CHD). Children with CHD are at increased risk for OSA and may be susceptible to further cardiovascular consequences due to OSA but the extent and nature of such cardiovascular effects of OSA are unknown. Methods: Children (6-17 years old) with corrected CHD without current cyanosis or Down syndrome were recruited from pediatric cardiology clinic. Home sleep tests were done to determine the presence and severity of OSA. OSA was defined as an obstructive apnea hypopnea index (oAHI) ≥1. Mild OSA was defined as an oAHI of ≥1 to <5 and moderate OSA was defined as an oAHI of ≥5 to <10. Standard clinically indicated echocardiograms were performed in clinic. Echocardiographic findings were compared between children with CHD with and without comorbid OSA using t-tests, Wilcoxon-sign rank tests as well as linear or logistic regression as appropriate. Results: Thirty-two children had sleep study and echocardiographic data available. OSA was present in 18 children (56%). OSA was mild in 89% and moderate in 11% of cases. There were no significant differences in age, body mass index, CHD severity, gender or ethnicity between children with and without OSA. Children with OSA had larger height-indexed right ventricular end-diastolic diameter (RVDi) compared to those without OSA (median 1.35, 95% CI 1.09, 1.56 vs. 1.21, 95% CI 1.01, 1.57; p=0.04). Children with moderate OSA had a reduced left ventricular shortening fraction compared to both those with mild OSA and no OSA (30.0 ± 6.1% vs. 38.7 ± 4.4%; p=0.009 and 39.2 ± 3.6%; p=0.007, respectively). Children with moderate OSA had increased left ventricular end-systolic diameter compared to those with mild OSA and no OSA (3.4 ± 0.4 cm vs. 2.5 ± 0.4; p=0.007 and 2.4 ± 0.5; p=0.001, respectively). Children with an RVDi above the median were seven times more likely to have OSA than those with an RVDi below the median (odds ratio 6.9.; 95% CI 1.3, 35; p=0.02). Conclusions: OSA is associated with changes in cardiac morphology and reduced contractility in children with CHD. Additionally, the presence of right ventricular dilation may suggest the need for OSA evaluation in children with CHD.

Background: Characterizing International Classification of Disease (ICD-9) code validity is essential given widespread use of hospital discharge and claims databases in research. Estimates for acute stroke vary depending on the codes investigated. We sought to estimate the validity of ICD-9 codes grouped according to the 2013 American Heart Association/ American Stroke Association (AHA/ASA) updated stoke definition and to explore differences by patient characteristics and study site. Methods: Medical records (N=4,260) containing ICD-9 codes 430-438 or stroke keywords in the discharge summary were abstracted for hospitalizations of Atherosclerosis Risk in Communities (ARIC) Study cohort members from 1987-2010. A computer algorithm and physician reviewer identified definite and probable ischemic stroke, intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH) with differences adjudicated by a second physician. Using ARIC diagnosis as a gold standard, we calculated the positive predictive value (PPV) and sensitivity of groups of ICD-9 codes matched to stroke subtypes by the AHA/ASA (ischemic stroke: 433.01, 433.11, 433.21, 433.31, 433.81, 433.91, 434.01, 434.11, 434.91; ICH: 431; SAH: 430). We excluded codes for spinal and retinal infarcts (336.1, 362.31, 362.32), which were not validated in ARIC (N=3 events). Results: Thirty-three percent of 4,260 hospitalizations were validated as definite or probable strokes (1,251 ischemic, 120 ICH, 46 SAH), and 30% (1,276 of 4,260) of hospitalizations included ICD-9 codes identified by the AHA/ASA. The AHA/ASA code groups had PPV 76% and 68% sensitivity, compared to PPV 40% and 95% sensitivity for ICD-9 codes 430-438 (not 435) traditionally used to identify stroke. For ischemic stroke, AHA/ASA identified ICD-9 codes were present for 1,043 hospitalizations. Among these, PPV was 76% overall and was slightly higher for blacks (80%, N=400) compared to whites (74%, N=643; p=0.04). However, differences by race diminished conditional undergoing a CT scan or MRI (blacks 81%, N=390; whites 78%, N=601). Among whites, PPV for ischemic stroke ranged from 60-79%, and sensitivity ranged from 60-70% across study sites. ICD-9 codes 430-431 for ICH and SAH were present for 225 hospitalizations and had PPV 61%. PPV was higher among blacks (73%, N=89) compared to whites (53%, N=136; p=0.003), and differences by race were not diminished conditional on undergoing a CT scan or MRI. Among whites, PPV for ICH and SAH ranged from 38-60%, and sensitivity ranged from 78-89% across study sites. Conclusion: New AHA/ASA code groups had higher PPV but lower sensitivity for identifying acute stroke than a traditional code group. PPV was higher among blacks compared to whites and both PPV and sensitivity varied by study site. These data may be useful for calibrating estimates of stroke incidence generated from administrative claims data and in sensitivity analyses.

Therefore, the problem of rational use of natural resources, in particular protection of early spring plant species is very important. However, literary sources analysis only reveals data on the biology of species of this genus. The present research,conducted in the spring of 2017-2019, focuses on anatomical and morphological features of two Altai species: Gagealutea and Gagea minima; these features were studied, clarified and confirmed by drawings and photographs. The anatomical structure of the stem and leaf blade was studied in detail. The obtained research results will prove useful for studies of medicinal raw materials and honey plants. The aforementioned species are similar in morphological features, yet G. minima issmaller in size, and its shoots appear earlier than those of other species Keywords: Flora,gageas,Altai species,vegetative organs., Refference: I.

Voropaeva,Viktoriay A. Kolomytseva, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00042 Abstract: This study was aimed at examining the influence of succession cropping on the economic efficiency of no-till field crop rotations on the black earth in the zone of unstable moistening of the Stavropol krai. A long-term stationary experiment was conducted to examine for the purpose nine field crop rotation patterns different in the number of fields (four to six), set of crops, and their succession in crop rotation. The respective shares of legumes, oilseeds, and cereals in the cropping pattern were 17 to 33, 17 to 40, and 50 to 67 %. It has been established that in case of no-till field crop cultivation the economic efficiency of plant production depends on the set of crops and their succession in rotation. The most economically efficient type of crop rotation is the soya-winter wheat-peas-winter wheat-sunflower-corn six-field rotation with two fields of legumes: in this rotation 1 ha of crop rotation area yields 3 850 grain units per ha at a grain unit prime cost of 5.46 roubles; the plant production output return and profitability were 20,888 roubles per ha and 113 %, respectively. The high production profitabilities provided by the soya-winter wheat-sunflower four-field and the soya-winter-wheat-sunflower-corn-winter wheat five-field crop rotation are 108.7 and 106.2 %, respectively. The inclusion of winter wheat in crop rotation for two years in a row reduces the second winter wheat crop yield by 80 to 100 %, which means a certain reduction in the grain unit harvesting rate to 3.48-3.57 thousands per ha of rotation area and cuts the production profitability down to 84.4-92.3 %. This is why, no-till cropping should not include winter wheat for a second time Keywords: No-till technology,crop rotation,predecessor,yield,return,profitability, Refference: I Badakhova G.

View | Download DEVELOPMENT AND TESTING OF AUTONOMOUS PORTABLE SEISMOMETER DESIGNED FOR USE AT ULTRALOW TEMPERATURES IN ARCTIC ENVIRONMENT Authors: Mikhail A. Abaturov,Yuriy V. Sirotinskiy, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00043 Abstract: This paper is concerned with solving one of the issues of the general problem of designing geophysical equipment for the natural climatic environment of the Arctic. The relevance of the topic has to do with an increased global interest in this region. The paper is aimed at considering the basic principles of developing and the procedure of testing seismic instruments for use at ultralow climatic temperatures. In this paper the indicated issue is considered through the example of a seismic module designed for petroleum and gas exploration by passive seismoacoustic methods. The seismic module is a direct-burial portable unit of around 5 kg in weight, designed to continuously measure and record microseismic triaxial orthogonal (ZNE) noise in a range from 0.1 to 45 Hz during several days in autonomous mode. The functional chart of designing the seismic module was considered, and concrete conclusions were made for choosing the necessary components to meet the ultralow-temperature operational requirements. The conclusions made served for developing appropriate seismic module. In this case, the components and tools used included a SAFT MP 176065 xc low-temperature lithium cell, industrial-spec electronic component parts, a Zhaofeng Geophysical ZF-4.5 Chinese primary electrodynamic seismic sensor, housing seal parts made of frost-resistant silicone materials, and finely dispersed silica gel used as water-retaining sorbent to avoid condensation in the housing. The paper also describes a procedure of low-temperature collation tests at the lab using a New Brunswick Scientific freezing plant. The test results proved the operability of the developed equipment at ultralow temperatures down to -55°C. In addition, tests were conducted at low microseismic noises in the actual Arctic environment. The possibility to detect signals in a range from 1 to 10 Hz at the level close to the NLNM limit (the Peterson model) has been confirmed, which allows monitoring and exploring petroleum and gas deposits by passive methods. As revealed by this study, the suggested approaches are efficient in developing high-precision mobile seismic instruments for use at ultralow climatic temperatures. The solution of the considered instrumentation and methodical issues is of great practical significance as a constituent of the generic problem of Arctic exploration.

View | Download COMPARATIVE ANALYSIS OF RESULTS OF TREATMENT OF PATIENTS WITH FOOT PATHOLOGY WHO UNDERWENT WEIL OPEN OSTEOTOMY BY CLASSICAL METHOD AND WITHOUT STEOSYNTHESIS Authors: Yuriy V. Lartsev,Dmitrii A. Rasputin,Sergey D. Zuev-Ratnikov,Pavel V.Ryzhov,Dmitry S. Kudashev,Anton A. Bogdanov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00044 Abstract: The article considers the problem of surgical correction of the second metatarsal bone length. The article analyzes the results of treatment of patients with excess length of the second metatarsal bones that underwent osteotomy with and without osteosynthesis. The results of treatment of patients who underwent metatarsal shortening due to classical Weil-osteotomy with and without osteosynthesis were analyzed. The first group consisted of 34 patients. They underwent classical Weil osteotomy. The second group included 44 patients in whomosteotomy of the second metatarsal bone were not by the screw. When studying the results of the treatment in the immediate postoperative period, weeks 6, 12, slightly better results were observed in patients of the first group, while one year after surgical treatment the results in both groups were comparable. One year after surgical treatment, there were 2.9% (1 patient) of unsatisfactory results in the first group and 4.5% (2 patients) in the second group. Considering the comparability of the results of treatment in remote postoperative period, the choice of concrete method remains with the operating surgeon.

Shulunova,Alexander I.Sidelnikov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00045 Abstract: Purpose.To determine the quantitative echogenicity indicators (and their ratio) of the layers of stomach and small intestine wall in healthy dogs. Methods. A prospective 3-year study of 86 healthy dogs (aged 1-7 yrs) of different breeds and of both sexes. Echo homogeneity and echogenicity of the stomach and intestines wall were determined by the method of Silina, T.L., et al. (2010) in absolute values ​​of average brightness levels of ultrasound image pixels using the 8-bit scale with 256 shades of gray. Results. Quantitative echogenicity indicators of the stomach and the small intestine wall in dogs were determined. Based on the numerical values ​​characterizing echogenicity distribution in each layer of a separate structure of the digestive system, the coefficient of gastric echogenicity is determined as 1:2.4:1.1 (mucosa/submucosa/muscle layers, respectively), the coefficient of duodenum and jejunum echogenicity is determined as 1:3.5:2 and that of ileum is 1:1.8:1. Clinical significance. The echogenicity coefficient of the wall of the digestive system allows an objective assessment of the stomach and intestines wall and can serve as the basis for a quantitative assessment of echogenicity changes for various pathologies of the digestive system Keywords: Ultrasound (US),echogenicity,echogenicity coefficient,digestive system,dogs,stomach,intestines, Refference: I.

When studying the temporal organization of physiological functions, the rhythm parameters of physiological functions were determined, followed by processing the results using the Cosinor Analysis program, which reveals rhythms with an unknown period for unequal observations, evaluates 5 parameters of sinusoidal rhythms (mesor, amplitude, acrophase, period, reliability). The essence of desynchronization is the mismatch of circadian rhythms among themselves or destruction of the rhythms architectonics (instability of acrophases or their disappearance). Desynchronization with respect to the rhythmic structure of the body is of a disregulatory nature, most pronounced in pathological desynchronization. High neurotism, increased anxiety reinforces the tendency to internal desynchronization, which increases with stress. During examination stress, students experience a decrease in the stability of the temporary organization of the biosystem and the tension of adaptive mechanisms develops, which affects attention, mental performance and the quality of adaptation to the educational process. Time is shortened and the amplitude of the “initial minute” decreases, personal and situational anxiety develops, and the level of psychophysiological adaptation decreases. The results of the work are priority because they can be used in assessing quality and level of health.

The difference between active and passive qualitative comparison is shown, two triadic models of passive and active comparison and models for comparing two and three objects are described. Triadic comparison models are proposed as an alternative to dyadic comparison models. Comparison allows finding the common and the different; this approach is proposed for the analysis of the nomothetic and ideographic method of obtaining knowledge. The nomothetic method identifies and evaluates the general, while the ideographic method searches for unique in parameters and in combinations of parameters. Triadic comparison is used in systems and methods of argumentation, as well as in the analysis of consistency/inconsistency.
