19537 Background: Anemia is a frequent complication in lymphoma pts receiving chemotherapy (CT). However, the exact incidence of anemia with the current regimens and risk factors for severe anemia are not well established. Methods: A retrospective cohort study was conducted to determine the incidence of anemia requiring transfusions (Tx). Medical records of all newly referred lymphoma pts (n=1046) in 2003 were reviewed. Logistic regression analysis was performed to identify the clinical and laboratory features correlated with anemia in lymphoma pts during initial regimen received. Results: 425 pts who received ≥ 1 cycle of treatment at MDACC were included in this analysis. Median age was 57 (range 17–87) with 262 (62%) newly diagnosed. Most common first regimens were CHOP (29%), Hyper-CVAD ± Ara-c-MTX (23%), and ABVD (8%) (± rituxan- R).The total number of cycles 1638 (median 3, range, 1–10). The incidence of anemia requiring PRBC Tx was 32 % (136/425) of pts and 14% (231/1638) of cycles (median cycle-2 for Tx). The incidence of PRBC Tx ranged from 8% to 17 % in each cycle. The incidence of PRBC Tx among most common regimens were Hyper-CVAD/ Ara-c/MTX 69 %( 66/95), CHOP 23% (29/125), and ABVD 6% (2/34). In the univariate regression analysis, CT, stage, extranodal/BM involvement, histology, Hb, Ca, β2M, LDH, WBC/lymphocyte counts, were significantly associated with the Txs. Using multivariate logistic regression, baseline Hb (< 12 g/dL vs. ≥ 12 g/dL: OR 2.659, 95% CI 1.670 to 4.232, p< 0.0001), extra nodal involvement (± : OR 2.578, 95% CI 1.609 to 4.133, p<0.0001), and CT (high vs low risk: OR 3.889, 95% CI 2.446 to 6.183, p<0.0001) were the most important baseline risk factors for PRBC Txs. Conclusions: The incidence of anemia in this population is high in early cycles. Baseline pt characteristics including Hb (<12g/dL), extra nodal involvement, and high risk CT were found to be significant risk factors predictive for anemia and Txs. These findings could be useful to identify high risk pts for consideration of prophylaxis with erythropoietic agents for prevention of anemia. No significant financial relationships to disclose.

19616 Background: Neutropenic fever (NF) can be a serious complication of chemotherapy (CT) in lymphoma patients (pts), however the exact incidence with the current regimens and risk factors for NF are not well known. Methods: A retrospective cohort study was conducted to determine the incidence of NF, and logistic regression analysis were performed to identify the clinical and laboratory features correlated with NF in lymphoma. Medical records of all newly referred lymphoma pts (n=1046) in 2003 were reviewed. Results: 425 pts who received ≥ 1 cycle of treatment at MDACC were included in the analysis. Median age was 57 (range 17–87) with 262 (62%) newly diagnosed. Most common first regimens were (± rituxan) CHOP (29%), Hyper-CVAD ± Ara-c-MTX (23%), and ABVD (8%), with the total number of cycles were 1638 (median 3, range, 1–10). NF was observed in 23 % (97/425) of pts and 8 % (123/1638) of cycles, with the highest number in cycle 1 (49/123). The NF incidence among most common regimens were (± rituxan) Hyper-CVAD/ Ara-c/MTX 53% (31/58), Hyper-CVAD 24% (9/37), CHOP 22% (27/125), and ABVD 6% (2/34), and most common subtypes were MCL (33%), LCL (23%), HD (16%), and FL (13%). In the univariate regression analysis, CT, Hb, Ca, LDH, lymphocyte (ALC) and neutrophil (ANC) counts, were significantly associated with the NF. Using multivariate logistic regression, baseline ALC count (=1000 vs. >1000/μL: OR=2.251, 95% CI, 1.194 to 4.244, p=0.0121), Hb (<12 g/dL vs. ≥ 12g/dL: OR=2.117, 95% CI, 1.122 to 3.996, p=0.0207), age (>60 vs. ≤60: OR=2.035, 95% CI, 1.066 to 3.884, p=0.0312), CT (high vs. low risk: OR=2.913, 95% CI, 1.520 to 5.583, p=0.0013) were the most important baseline risk factors for NF in cycle-1. Conclusions: The incidence of NF in this population is high in cycle 1. Baseline pt characteristics including old age, high risk CT, low ALC and Hb were found to be significant risk factors predictive for NF in cycle-1. These findings could be useful to identify high risk pts for consideration of treatment approaches for prevention of NF. No significant financial relationships to disclose.

Abstract Background: Current prognostic models in primary myelofibrosis (PMF) target overall survival (OS) and utilize MIPSS70 (mutation-enhanced international prognostic scoring system for transplant-age patients), MIPSS70+ version 2.0 (karyotype-enhanced MIPSS70) and GIPSS (genetically-inspired prognostic scoring system, which is based on mutations and karyotype) (JCO 2018;36:310; JCO doi: 10.1200/JCO.2018.78.9867; Leukemia. 2018;doi:10.1038/s41375-018-0107). In the current study, we used logistic regression statistics to identify risk factors for leukemic transformation (LT) within 5 years of diagnosis/referral (i.e. early events) and also performed Cox regression analysis of overall leukemia-free survival (LFS). Methods : Study patients were recruited from the Mayo Clinic, Rochester, MN, USA. Diagnoses of LT and chronic phase PMF were confirmed by both clinical and bone marrow examinations, in line with the 2016 World Health Organization criteria (Blood. 2016;127:2391); specifically, LT required presence of ≥20% blasts in the peripheral blood (PB) or bone marrow (BM) (Blood 2016;127:2391). Statistical analyses considered clinical and laboratory data collected at the time of initial PMF diagnosis or Mayo Clinic referral point. Logistic regression statistics was used to identify predictors of LT at 5 years from initial diagnosis/referral; in the particular method, patients with documented LT within 5 years were "uncensored" while those followed up for at least 5 years, without developing LT, were "censored"; the analysis excluded patients without LT and not followed for at least 5 years. In addition, Cox regression analysis was performed to identify risk factors for overall LFS. The JMP® Pro 13.0.0 software from SAS Institute, Cary, NC, USA, was used for all calculations. Results: 1,306 patients with PMF (median age 65 years; 63% males) were included in the current study; MIPSS70+ version 2.0 risk distribution was 20% very high risk, 41% high risk, 19% intermediate risk, 16% low risk and 4% very low risk. 149 (11%) patients were documented to experience LT, and compared to the remaining patients (n=1157), they were more likely to be males (p=0.02) and mutated for ASXL1 (p=0.01), SRSF2 (0.001) and IDH1 (0.02) and present with higher risk MIPSS70+ version 2.0 (p=0.02). Multivariable logistic regression identified the following as predictors of LT in the first 5 years of disease: IDH1 mutation (odds ratio; OR 78.4), very high risk (VHR) karyotype (OR 57.6), ASXL1 mutation (OR 15.1), age >70 years (OR 13.3), SRSF2 mutation (OR 8.5), male sex (OR 6.9), PB blasts ≥3% (OR 5.4), presence of moderate or severe anemia, adjusted for sex (OR 3.6) and constitutional symptoms (OR 3.1). On Cox regression analysis, the following were associated with inferior LFS: IDH1 mutation (HR 4.3), PB blasts ≥3% (HR 3.3), SRSF2 mutation (HR 3.0), age >70 years (HR 2.1), ASXL1 mutation (HR 2.0) and presence of moderate or severe anemia, adjusted for sex (HR 1.9). Subsequently, HR-based risk point allocation resulted in highly discriminating LT predictive model with HR (95% CI) of 39.4 (10.8-114) for high risk and 4.1 (2.4-7.3) for intermediate risk (Figure 1). Conclusions: The current study identifies IDH1 mutation as a main predictor of LT in PMF. Our study also implicates SRSF2 and ASXL1 mutations and VHR karyotype as other genetic markers of early LT. Other independent contributors of early LT and inferior LFS, overall, included PB blasts ≥3%, moderate to severe anemia and older age. We provide LT prediction model, based on these variables, with leukemia risk ranging from 8% to 57%. Disclosures No relevant conflicts of interest to declare.

Abstract Purpose: To describe the rate and time of onset of serious thromboembolic (TE) complications within the first 90 postoperative days in an unselected population of THR patients. Secondary to analyse the data base for possible risk factors of TE. Material and method: Five hundred (430 primary THR and 70 revision THR) consecutive patients undergoing THR in Frederiksborg County, Denmark from January 2004 until May 2005 participated. The patients were interviewed the day before surgery for medical history. On the 5th postoperative day and at a telephone interview 90 days postoperatively patients were asked about signs and symptoms of acute myocardial infarction (AMI), pulmonary embolism (PE), deep vein thrombosis (DVT), transitory cerebral ischemia (TCI)/stroke, retinal vein thrombosis (RVT) and other cardio vascular events. All events were validated in hospital and/or the general practitioners files, using international criteria. All patients except 1 had chemical thromboprophylaxis during hospitalization. No patients had extended thromboprophylaxis after discharge. 498 patients had 90 days follow-up. Two patients withdrew their consent. Results: 24 patients (4.8%) experienced at least one serious TE complication during the first 90 days after the operation. Two (0.4%) patients died in relation to the operation (no autopsy was performed). Five patients (1.0%) had PE. One patient (0.2%) had AMI, 10 (2.0%) had DVT, two (0.4%) had RVT and four (0.8%) had TCI. Two patients experienced two events - one had AMI and later on a TCI, another had PE and TCI on the same day. Nine patients had their first event during the first five postoperative days - 15 patients had their first event after the 5th postoperative day. The only significant risk factor found in a backward logistic regression analysis including interaction (test for confounder/bias) was the length of the operation P=0.003 OR= 1.016 (1.005–1.026). This study has not been able to show any significant correlation between age, gender, co-morbidities, preoperative hemoglobin value ore platelet count, high ASA-score, kind of anesthesia, indication for operation or use of cement or interactions between the above in the logistic regression analysis, but individually all these factors were significant risk factors in the introductory bivariate analysis. Discussion: This study shows that venous and arterial thrombotic complications persist to be a major contribution to postoperative morbidity and mortality after elective total hip replacement, despite of rigorous early mobilization and optimized regimens of prevention of thromboembolism. After this study has been performed ACCP has recommended extend prophylaxis by LMWH, pentasaccharide or warfarin up to 4–5 weeks after total hip replacement. Further research to identify patients at risk is warranted to optimize risk/benefit of total hip replacement and prevention of venous and arterial thromboembolism. The majority of events occurred after discharge calling for improvement of the post-discharge period to reduce the risk of serious thromboembolism.

Abstract Background Silent infarcts are associated with impaired cognitive functioning and have been shown to be predictors of stroke (Miller ST J Pediatr 2001). Until now, reported risk factors for silent infarcts were low pain event rate, history of seizures, high leukocyte count and Sen bS haplotype (Kinney TR Pediatrics 1999). Here, we seek to define the prevalence and risk factors of silent infarcts in the Créteil SCA pediatric cohort comprising patients assessed at least yearly by transcranial doppler (TCD) since 1992, and by MRI/MRA. Methods This study retrospectively analyzed data from the Créteil cohort stroke-free SS/Sb0 children (280; 134 F, 146 M), according to institutional review board. Time-averaged mean of maximum velocities higher than 200 cm/sec were considered as abnormal, resulting in initiation of a transfusion program (TP). A switch to hydroxyurea was proposed to patients with normalized velocities (&lt; 170 cm/sec) and normal MRA on TP, although TP was re-initiated in case of abnormal velocities recurrence. Patients with “conditional” velocities (170–199 cm/sec) were assessed by TCD 4 times yearly. Alpha genes and beta-globin haplotypes were determined. Baseline biological parameters (G6PD activity; WBC, PMN, Reticulocytes, Platelets counts; Hemoglobin, Hematocrit, HbF, LDH levels; MCV; SpO2) were obtained a minimum of 3 months away from a transfusion, one month from a painful episode, after 12 months of age, before the first TCD, and always before therapy intensification. Results. Patients were followed for a total of 2139 patient-years. Alpha-Thal was present in 114/254 patients (45%) and 27/241 (11.2%) had G6PD deficiency. Beta genotype, available in 240 patients, was BaBa in 102 (42.5%), BeBe in 54 (22.5%), SeSe in 19 (7.9%) and “other” in 65 (27.1%); TCD was abnormal in 52 of 280 patients (18.6%). MRA showed stenoses in 30 of 226 evaluated patients (13.3%) while MRI demonstrated presence of silent infarcts in 81/280 patients (28.9%). Abnormal TCD (p&lt;0.001), G6PD deficiency (p=0.008), high LDH (p=0.03), and low Hb (p=0.026) were significant risk factors for stenoses by univariate analysis while multivariate analysis retained only abnormal TCD as a significant risk factor for stenoses ([OR= 10.6, 95% CI (4.6–24.4)]; p&lt;0.001). Univariate logistic regression analysis showed that the risk of silent infarcts was not related to alpha-Thal, beta genotype, abnormal TCD, WBC, PMN, platelets, reticulocyte counts, MCV, LDH level, HbF %, pain or ACS rates but was significantly associated with stenoses detected by MRA (p&lt;0.001), gender (male; p=0.04), G6PD deficiency (p=0.05), low Hb (p=0.016) and Hct (p=0.012). Multivariate logistic regression analysis showed that gender ([OR= 2.1, 95% CI (1.03–4.27)]; p=0.042), low Hb ([OR= 1.4, 95% CI (1.0–1.1)]; p=0.05) and stenoses ([OR= 4.8, 95% CI (1.88–12.28)]; p=0.001) were all significant independent risk factors for silent infarcts. The presence of stenoses was the only significant risk factor for silent infarcts in patients with a history of abnormal TCD ([OR= 5.9, 95% CI (1.6–21.7)]; p=0.008). Conclusion We recently showed that G6PD deficiency, absence of alpha-Thal, and hemolysis are independent significant risk factors for abnormal TCD in stroke-free SCA patients (Bernaudin et al, Blood, 2008, in press). Here, we report that an abnormal TCD is the most significant risk factor for stenoses and, expanding previous studies, we demonstrate that stenoses, low Hb and gender are significant independent risk factors for silent infarcts.

Osteoporosis is a disease characterized by deterioration of bone tissue and mass, with an increasing global prevalence. Therefore, the discovery of biomarkers for osteoporosis would help to guide appropriate treatment. Circulating microRNAs (miRNAs) have become increasingly recognized as biomarkers for detecting diseases. However, few studies have investigated the association of circulating miRNA with osteoporosis in the general population. The aim of this study was to identify miRNA associated with osteoporosis in a general resident health check-up for potential use as an osteoporosis biomarker. We conducted a cross-sectional study as part of a health check-up program and recruited 352 volunteers (139 men, 213 women, mean age 64.1±9.6 years). Osteoporosis was diagnosed according to the WHO classification. Twenty-two candidate microRNAs were screened through real-time quantitative PCR, and miRNAs associated with osteoporosis were analyzed using logistic regression analysis including other risk factors. In total, 95 females and 30 males were diagnosed with osteoporosis with bone mineral density tests (BMD: T‐score<−2.5). We found that miR195 was significantly lower in females, while miR150 and miR222 were significantly higher in males. The results of the logistic regression analysis indicated that in females, higher age and lower miR195 (odds ratio: 0.45, 95% confidential interval: 0.03–0.98) were significant risk factors for lower BMD, while the presence of a smoking habit and lower miR150 (odds ratio: 1.35, 95% confidential interval: 1.02–1.79) were significant risk factors for osteoporosis. Serum levels of miR195 and miR150 are independently associated with low bone mineral density in females and males, respectively.

Objective: Patients with ADHD are at increased risk of acquiring COVID-19. The present study assessed the possibility that ADHD also increases the risk of severe COVID-19 infection. Method: We assessed 1,870 COVID-19 positive patients, aged 5 to 60 years, registered in the database of Leumit Health Services (LHS, Israel), February to -June 2020, of whom 231 with ADHD. Logistic regression analysis models evaluated the association between ADHD and the dependent variables of being symptomatic/referral to hospitalization, controlling for demographic and medical variables. Results: Age, male sex, and BMI were confirmed to be significant risk factors for increased COVID-19 severity. ADHD was found to be associated with increased severity of COVID-19 symptoms ( OR = 1.81, 95% CI [1.29, 2.52], p < .05) and referral to hospitalization ( OR =1.93, 95% CI [1.06, 3.51], p = .03). Conclusion: ADHD is associated with poorer outcomes in COVID-19 infection.

Objectives: The purpose of this study was to assess the prevalence and characteristics of dental erosion in children aged 2-4 years old and 12 years old. Study design: 243 subjects were recruited from daycare centers, preschools, and grade schools; they received dental examinations assessing their condition of dental erosion, including both depth and area of tooth surface loss on four maxillary incisors. Questionnaires were given to the subjects to obtain socio-demographic, oral health behaviors at home, and access to dental care. Dental erosion was analyzed and risk factors were assessed using Chi-Square and logistic regression analysis. Results: The subjects were 60% Caucasians, 31% Black, 7% Hispanic and others were 2%. 34% of children could not get the dental care they needed within the past 12 months and 61% of all children brushed their teeth twice or more daily. Overall, 12% of study children had dental erosion with 13% for 2-4 years old and 10% for 12 years old, with the majority of erosive lesions within enamel. Family income (OR 3.98, p=0.021) and acidic fruit juice consumption (OR 2.38, p=0.038) were significant risk factors for dental erosion, even after controlling for other factors, such as source of drinking water and oral hygiene using logistic regression analysis. Conclusions: Dental erosion is a relatively common problem among the children in this study and it is seen as a multi-factorial process.

Study Design Retrospective cohort study. Objectives The aim was to examine cervical spinal cord compression (SCC) in adult scoliosis and clarify the prevalence of and risk factors for cervical SCC. Methods This study included 270 adult scoliosis patients and 1211 healthy volunteers. Cervical SCC was evaluated on cervical magnetic resonance imaging (MRI). The rates of SCC for those with adult scoliosis and the healthy volunteers were compared. Logistic regression analysis was conducted to examine the factors associated with cervical SCC on MRI. Results In cases with adult scoliosis, preoperative major scoliosis curve was 56.0° ± 18.8°, and cervical SCC was detected in 25 patients (9.3%). Among the healthy volunteers, 64 cases with cervical SCC were detected. Only in cases with adult scoliosis, logistic regression analysis revealed higher age (OR 1.09, 95% CI 1.04–1.14, P < .001), narrow canal diameter (OR 2.27, 95% CI 1.35–3.85, P = .002), and inferior sagittal balance (OR 2.45, 95% CI 1.02–5.89, P = .04) as significant risk factors. In the logistic regression analysis in all subjects (including adult scoliosis and healthy volunteers), higher age (OR 1.08, 95% CI 1.06–1.10, P < .001) and narrow canal diameter (OR 1.62, 95% CI 1.37–1.92, P < .001) were also found to be significant risk factors, but the presence of scoliosis was not a significant factor. Conclusions Adult scoliosis itself was not significantly associated with cervical SCC. Inferior sagittal balance in addition to scoliosis constituted a significant risk factor for cervical SCC.

Background: Possible risk factors for postoperative intra-abdominal abscess (IAA) formation after laparoscopic appendectomy (LA) remain controversial. A perforated appendicitis, diabetes mellitus, peritoneal irrigation, obesity and age are considered to be possible risk factors for postoperative IAA, but the existing evidence is insufficient. This study aimed to identify the risk factors for IAA formation in patients receiving LA. Methods: Between January 2010 and December 2013, 1,817 patients who underwent 3-port LA were enrolled in this study. Patients were classified into 2 groups according to the development of postoperative IAA, and the differences between the groups were analyzed. Results: The incidence of IAA after LA was 1.5%, and the only identified risk factor for IAA was peritoneal irrigation. On logistic regression analysis of those patients who received peritoneal irrigation, suppurative appendicitis and non-placement of the peritoneal drain were found to be significant risk factors for the development of IAA. Conclusions: Peritoneal irrigation in a case of abdomen contamination was shown to be a risk factor for the development of postoperative IAA after LA. When peritoneal irrigation is performed, surgeons should consider using peritoneal drainage and postoperative antibiotics (including anti-anaerobic antibiotics) to prevent postoperative IAA formation.
