Abstract Abstract 3395 Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), represents a public health concern in Western and Asian countries. Venous thromboembolism often complicates the course of hospitalized patients but may also affect ambulatory and otherwise healthy people. The classic risk factors for VTE are cancer, surgery, prolonged immobilization, fracture, paralysis, oral contraceptive use, and hereditary coagulopathies. In addition to these classic risk factors, microparticle containing microRNA is a known risk factor for both arterial and venous thrombosis. The aim of study was to investigate genetic association between microRNAs or microRNA-biogenesis genes and VTE. We selected 6 well-studied polymorphisms of miR-146a (rs2910164), miR-196a2 (rs11614913), miR-499 (rs3746444), DICER (rs3742330), DROSHA (rs10719), and RAN (rs14035). Patients with consecutive VTE with recent (<6 months) objective diagnosis of DVT or PE, who visited to the CHA Bundang Medical Center (Seongnam, Korea) or Keimyung University hospital (Daegu, Korea) between May 2005 and December 2009, were enrolled in the study. We enrolled the patients with symptomatic VTE and excluded the patients with asymptomatic VTE. Venous thromboembolism was defined as provoked or unprovoked, depending on the presence or absence of any of the following risk factors: recent surgery (<3 months), recent trauma/fracture (<3 months), immobilization (>7 days), malignancy, stroke, severe medical disease, autoimmune disease, pregnancy, use of oral contraceptives, and known inherited thrombophilia. Venous thromboembolism was classified as provoked in the presence of at least one of these risk factors. The control group was selected among patients visiting the CHA Bundang Health Promotion Center for periodic health examinations, who had no medical history of VTE. The Institutional Review Board of CHA Bundang Medical Center approved the research protocol and written informed consent was obtained from all participating individuals. Genotyping of microRNA and microRNA-biogenesis gene polymorphisms was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. Multivariate logistic regression was used to calculate strength of association. The genetic distributions of microRNA and microRNA-biogenesis gene polymorphisms were in Hardy-Weinberg equilibrium (Table 1). RAN rs14035 CC genotype was associated with increased VTE risk (adjusted odds ratio [AOR], 1.640; 95% confidence interval [CI], 1.106–2.432; P=0.014; Table 1). The statistical significance of RAN rs14035 CC was strengthened in unprovoked VTE patients (AOR, 2.478; 95% CI, 1.410–4.357; P=0.002; Table 2). Although other microRNA-related polymorphisms showed differences between controls and VTE patients, there were not positive statistical significances. In conclusion, RAN rs14035 CC may be a possible predisposing factor for VTE development. Disclosures: No relevant conflicts of interest to declare.

Abstract Cerebral sinus vein thrombosis (CSVT) is a rare disease with significant neurological sequellae and high mortality rate. Incidence of CSVT diagnosis in the western world has increased despite the reduced occurrence of infectious sinus thrombosis related to otitis media and mastoiditis. The objective of this study was to identify risk factors that may explain the predisposition to the site specific thrombosis based on patients from a single tertiary medical center. The study included 90 consecutive patients aged 15 and up that were diagnosed with acute CSVT from January 2002 to September 2014 at the Sheba Medical Center. As a control group we used the data extracted from the national trauma registry for the years 2012 and 2013 and from Maccabi Healthcare Services, the second largest health care maintenance organization (HMO) in Israel. Trauma history up to one month prior to diagnosis of CVST was found in 13 (14%) patients (10 men and 3 women). Six patients had skull fractures, the others had blunt trauma. Data from the national trauma registry were used to compute annual age and gender specific head trauma rates. The overall SMR was 941 (p < 0.0001); the separate results for men and women were 1206 and 543, respectively. Another important risk factor was infections confined to the head and neck in 7% of the cases and brain tumor in 8%. At the time of CVST, 23 of 50 (46%) women had a hormonal risk factor. The SMR for OC use was 1.63 (p=0.0298). Prothrombotic polymorphisms were detected in 16 of 63 (25.4%) patients who were tested for factor V Leiden and prothrombin G20210A mutation (OR=3.47, p=0.002) in comparison to 49% in DVT patients (OR=9.95, p<0.0001). In 29 of 90 patients at least one of the risk factors for atherosclerosis (hypertension, diabetes or hypercholesterolemia) was discerned but this was very close to the expected number adjusted for sex and age and SMR was 0.98. None of the risk factors correlated with severity of disease and outcome. These data suggest that search for CVST in patients with recent trauma and headache even after intact head CT is required. The other risk factors, such as hormone related and prothrombotic polymorphisms, were not specific just for CVST and the latter play a lesser role in CVST than in DVT.

Background: Coronavirus disease 2019 (COVID-19) caused by acute respiratory syndrome coronavirus 2 (SARS2), is associated with significant morbidity and mortality. The aim of this study is to characterize risk factors and clinical features of COVID-19 disease in an adult cohort in Jeddah, Saudi Arabia. Methods: A retrospective case control study was conducted at King Abdulaziz University hospital (KAUH) in Jeddah, Saudi Arabia. Clinical and demographic data on patients presenting at KAUH with concern for COVID-19 disease between March 18 and May 18, 2020 were collected and analyzed. Results: Electronic medical records on 297 patients presenting at KAUH were reviewed. Of these, 175 (59%) tested positive for COVID-19 by polymerase chain reaction (PCR) and 122 (41%) tested negative. COVID-19 positive patients were more likely to be males (OR=1.59; 95% CI=1.22-2.07), and non-health care workers (OR=1.53; 95% CI=1.13-2.08). Hypertension (10%), diabetes (10%), and two or more concurrent co-morbid conditions (54.4%), were more prevalent among COVID-19 positive patients. Patients presenting with fever, cough, and loss of sense of taste or smell were more likely to test positive for COVID-19 (p=0.001, 0.008, 0.008, respectively. Radiological evidence of pneumonia was associated with confirmed COVID-19 disease. Dyspnea, cough and gastrointestinal symptoms were not associated with risk of COVID-19 at presentation. On admission, white blood cells, neutrophils, lymphocytes, eosinophils, basophils, and platelets were significantly lower among COVID-19 positive patients compared to controls. Surprisingly, D-dimer levels were lower among COVID-19 positive patients. Furthermore, only two patients developed thrombosis; one with pulmonary embolism and one with coronary artery thrombosis. Conclusion: Male gender, hypertension and diabetes were associated with risk of COVID-19 disease in this study population. D-dimer levels were not elevated in COVID-19 patients, and venous thromboembolism was not prevalent in cases, compared to controls. This is in contrast to previous reports on the association of COVID-19 disease with venous thromboembolism in other populations. Thus, individual and environmental risk factors may play an important role in the pathophysiology of thrombosis in COVID-19 disease. Disclosures No relevant conflicts of interest to declare.

Abstract Introduction: Venous thromboembolism (VTE) is an important cause of maternal morbidity and mortality throughout the developed world. VTE is multifactorial disease. The incidence of VTE increases 2–4 fold in pregnancy and is higher after caeserean section than after vaginal delivery. Individuals with F V Leiden mutation have 3–7 fold higher risk of VTE. The risk of VTE in women with heterozygous form of F V Leiden during pregnancy is considered to be low ( less than 3%), but some other data show higher risk ( almost 10%) according design of the studies. The aim of study: The assessment of the frequency of VTE in women with F V Leiden in heterozygous form in association with pregnancy and puerperium from the East Bohemia region and the comparison of our results with similar studies. Our results and available data should enable us to make an idea about the proper strategy of thromboprophylaxis in these settings. The frequency of F V Leiden is 2% in our region. It is retrospective case control study. Materials and methods: The assessment of the frequency of VTE in the group of 224 women with F V Leiden in association with 460 pregnancies. This group consists from women after VTE with F V Leiden in heterozygous form ( without other inherited thrombophilia and APS) and from asymptomatic family members with F V Leiden ( 104 index cases, 120 family members). The frequency of VTE was compared with the frequency of VTE in the control group of 201 women without F V Leiden in association with 422 pregnancies. This control group consists from asymptomatic family members of women from the first group without detection of F V Leiden and from women examined in our department during the assessment of the frequency of F V Leiden in our population, when F V Leiden was not diagnosed ( 101 asymptomatic family members, 100 healthy women). Coagulation work up was done in the period of 1996 – 2003. All women had at least one pregnant and all pregnancies were without thromboprophylaxis. The presence of F V Leiden mutation was determined after DNA extraction, polymerase chain reaction ( PCR) and Mnll restriction analyses. VTE ( DVT and PE) was objectively determined in all cases. Results: In the investigated group VTE occurred 44x during pregnancy and puerperium. In l7 cases VTE was manifested in pregnancy ( 1x in I. trimester, 2x in II. trimester, 14x in III. trimester), in 27 women VTE occurred in puerperium and always within the first 10 days after delivery. Proximal venous thrombosis was diagnosed in 34 cases, in 5 cases was complicated by pulmonary embolism. In 10 women thrombosis was distal. The frequency of VTE was 9,6%. The frequency of VTE in the control group was 0,24%. The results were statistically assessed by Fisher’s exact test in programme NCSS 2004. The frequency of VTE in the cohort of women with F V Leiden reached statistical significance in comparison with the control group. Conclusion: Pregnancy and puerperium have been found the risk factors for VTE in investigated group. Our data can be affected by high number of index cases in the first group. In spite of this result we do not recommend pharmacological thromboprophylaxis to all women and thromboprophylaxis is considered on individual basis after the assessment of all other risk factors of VTE.

SummaryA retrospective study was done to determine the incidence of and the risk factors predisposing to clinical venous thromboembolism (VTE) in patients treated for high grade gliomas. Medical records of 68 consecutive patients diagnosed and treated at Saint Francis Hospital and Medical Center from January 1986 to June 1991 were reviewed. The follow up was to time of death or at least 6 months (up to December 1991). All clinically suspected episodes of VTE were confirmed by objective tests. Sixteen episodes of VTE were detected in 13 patients for an overall episode rate of 23.5%. Administration of chemotherapy (p = 0.027, two tailed Fisher exact test) and presence of paresis (p = 0.031, two tailed Fisher exact test) were statistically significant risk factors for the development of VTE. Thrombotic events were more likely to occur in the paretic limb and this difference was statistically significant (p = 0.00049, chi square test, with Yates correction). No major bleeding complications were seen in the nine episodes treated with long term anticoagulation.We conclude that venous thromboembolic complications are frequently encountered in patients being treated for high grade gliomas and the presence of paresis and the administration of chemotherapy increases the risk of such complications.

Background and Aims: The importance of sessile serrated lesions (SSLs) in the pathogenesis of colorectal carcinoma has been recently established. These are supposed to cause the so-called “interval cancer”, having a rapidly progressive growth and being difficult to detect and to obtain an endoscopic complete resection. We aimed to establish the most important metabolic risk factors for sessile serrated lesions. Methods: We performed a retrospective case-control study, on a series of 2918 consecutive patients who underwent colonoscopy in Gastroenterology and Endoscopy Unit, County Clinical Emergency Hospital, Târgu-Mureș, Romania between 1 st of January 2015-31 th of December 2017. In order to evaluate the metabolic risk factors for polyps’ development, enrolled participants were stratified in two groups, a study group, 33 patients with SSLs lesions, and a control group, 138 patients with adenomatous polyps, selected by systematic sampling for age and anatomical site. Independent variables investigated were: gender, smoking, alcohol consumption, obesity, arterial hypertension, diabetes, hypercholesterolemia, hypertriglyceridemia, hyperuricemia, nonalcoholic liver disease. Results: For SSLs the most common encountered localization was the right colon in 30.55% of cases. By comparative bivariate analysis between SSLs group and control group, it was observed that hypertension (p=0.03, OR 2.33, 95 %CI 1.03-5.24), obesity (p=0.03, OR 2.61, 95 %CI 1.08-6.30), hyperuricemia (p=0.04, OR 2.72, 95 %CI 1.28-7.55), high cholesterol (p=0.002, OR 3.42; 95 %CI 1.48-7.87), and high triglycerides level (p=0.0006, OR 5.75; 95 %CI 1.92-17.2) were statistically associated with SSLs development. By multivariate analysis hypertension and hypertriglyceridemia retained statistical significance. Conclusions: Our study showed that the highest prevalence of SSLs was in the right colon and hypertension and increased triglycerides levels were associated with the risk of SSLs development. These risk factors are easy to detect in clinical practice and may help identifying groups with high risk for colorectal cancer, where screening is recommended.

Abstract Background and Aims Vascular calcification (VC) plays a major role in cardiovascular disease (CVD), which is one of the main causes of mortality in patients with chronic kidney disease (CKD). The study aims at early detection of breast arterial calcification (BAC) in different stages of CKD (stage 2, 3& 4) patients as an indicator of systemic VC. Method A case control study was conducted targeting CKD women, aged 18- 60 years old. The sample was divided into 3 groups; A,B,C (representing stage 2, 3 & 4 of CKD) from women who attended nephrology and Internal medicine clinics and admitted in inpatient ward in Suez Canal University Hospital. A 4th group (D) was formed as a control group and included women with normal kidney functions (each group (A, B, C, D) include 22 women). The selected participants were subjected to history taking, mammogram to detect BAC and biochemical assessment of lipid profile, Serum creatinine (Cr), Mg, P, Ca, PTH and FGF23. Results Our study detected presence of BAC in about 81.8% of hypertensive stage 4 CKD patients compared with 50% in stage 3 CKD, also in the majority of stage 4 CKD patients who had abnormal lipid profile parameters and electrolyte disturbance. Most of the variables had statistical significance regarding the presence of BAC. Conclusion Although it is difficult to determine the definite stage at which the risk of VC begins but in our study, it began late in stage 2 CKD, gradually increased prevalence through stage 3 and became significantly higher in stage 4. These results suggest that preventive strategies may need to begin as early as stage 2 CKD.

Abstract Several studies have demonstrated that higher levels of vitamin D are associated with better prognosis and outcomes in infectious diseases. We aimed to compare the vitamin D levels of paediatric patients with mild/moderate coronavirus disease 2019 (COVID-19) disease and a healthy control group. We retrospectively reviewed the medical records of patients who were hospitalised at our university hospital with the diagnosis of COVID-19 during the period between 25 May 2020 and 24 December 2020. The mean age of the COVID-19 patients was 10.7 ± 5.5 years (range 1–18 years); 43 (57.3%) COVID-19 patients were male. The mean serum vitamin D level was significantly lower in the COVID-19 group than the control group (21.5 ± 10.0 vs. 28.0 ± 11.0 IU, P < 0.001). The proportion of patients with vitamin D deficiency was significantly higher in the COVID-19 group than the control group (44% vs. 17.5%, P < 0.001). Patients with low vitamin D levels were older than the patients with normal vitamin D levels (11.6 ± 4.9 vs. 6.2 ± 1.8 years, P = 0.016). There was a significant male preponderance in the normal vitamin D group compared with the low vitamin D group (91.7% vs. 50.8%, P = 0.03). C-reactive protein level was higher in the low vitamin D group, although the difference did not reach statistical significance (9.6 ± 2.2 vs. 4.5 ± 1.6 mg/l, P = 0.074). Our study provides an insight into the relationship between vitamin D deficiency and COVID-19 for future studies. Empiric intervention with vitamin D can be justified by low serum vitamin D levels.

Background: Venous thromboembolism (VTE) is a frequent and potentially lethal condition. Venous thrombi are mainly constituted of fibrin and red blood cells, but platelets also play an important role in VTE formation. Information about VTE in patients with thrombocytopenia is, however, missing. Objectives: To identify VTE risk factors and describe treatment and outcome (bleeding episodes and mortality) in patients with thrombocytopenia. Patients/Methods: Patients with thrombocytopenia (platelet count <100 × 109/L) admitted to Odense University Hospital, Denmark, between April 2000 and April 2012 were included. Fifty cases had experienced VTE. Controls without VTE were matched 3:1 with cases on sex and hospital department. Medical records were examined, and data were analyzed using conditional logistic regression. Results: In multivariate analysis, platelet count <50 × 109/L (odds ratio [OR] 0.22, P < .05) and chronic liver disease (OR 0.05, 95% confidence interval [CI] 0.01-0.58) reduced the risk of VTE. Surgery (OR 6.44, 95% CI 1.37-30.20) and previous thromboembolism (OR 6.16, 95% CI 1.21-31.41) were associated with an increased VTE risk. Ninety-two percent of cases were treated with anticoagulants. There was no difference in bleeding incidence between cases and controls. Conclusions: Several known VTE risk factors also seems to apply in patients with thrombocytopenia. Also, patients with thrombocytopenia may be VTE risk stratified based on platelet count and comorbidities. Finally, patients having thrombocytopenia with VTE seem to be safely treated with anticoagulants without increased occurrence of bleeding.

Abstract Background Children require anesthesia for MRI to maintain immobility and reduce discomfort; clear indications about the best anesthesiologic management are lacking and each center developed its own protocol. Moreover, children with neuropsychiatric disorders more likely require sedation and are described in literature as more prone to general and respiratory complications. Aim of this study was to analyze the applicability of a sevoflurane-based approach, to describe general and respiratory complications and to identify risk factors in a pediatric neuropsychiatric population. Methods Retrospective cohort study, university Hospital (January 2007–December 2016). All the 1469 anesthesiologic records of children addressed from Neuropsychiatric Unit to undergo MRI under general anesthesia were analyzed; 12 patients equal or older than 18-year-old were excluded. We identified post-hoc nine macro-categories: static encephalopathies, metabolic/evolutive encephalopathies, epileptic encephalopathies, neuromuscular diseases, autistic spectrum disorders, migraine, psychiatric disorders, intellectual disabilities, others. A logistic regression model for events with low frequency (Firth’s penalized likelihood approach) was carried out to identify the mutually adjusted effect among endpoints (complications) and the independent variables chosen on the basis of statistical significance (univariate analysis, p ≤ 0.05) and clinical judgment. Results Of 1457 anesthesiologic records (age 4.0 (IQR 2.0 to 7.0) year-old, males 891 (61.2%), weight 17.0 (IQR 12.0 to 24.9) kg), 18 were cancelled for high anesthesiologic risk, 50 were cooperative, 1389 were anesthetized. A sevoflurane-based anesthesia was feasible in 92.3%; these patients required significantly less mechanical ventilation (8.6 vs. 16.2%; p = 0.012). Complications’ rate was low (6.2%; 3.1% respiratory). The risk for general complications increases with ASA score > 1 (OR 2.22, 95 CI% 1.30 to 3.77, p = 0.003), male sex (OR 1.73, 95% CI 1.07 to 2.81, p = 0.025), multi-drug anesthesia (OR 2.98, 95 CI% 1.26 to 7.06, p = 0.013). For respiratory complications, it increases with ASA score > 1 (OR 2.34, 95 CI% 1.19 to 4.73, p = 0.017), autumn-winter (OR 2.01, 95 CI% 1.06 to 3.78, p = 0.030), neuromuscular disorders (OR 3.18, 95 CI% 1.20 to 8.41, p = 0.020). We had no major complications compromising patients’ outcome or requiring admission to ICU. Conclusions Sevoflurane anesthesia is feasible and safe for children affected by neuropsychiatric disorders undergoing MRI. Specific risk factors for general and respiratory complications should be considered.

Objectives.To identify risk factors for infection with imipenem-resistant Pseudomonas aeruginosa and determine the impact of imipenem resistance on clinical and economic outcomes among patients infected with P. aeruginosa.Designs.An ecologic study, a case-control study, and a retrospective cohort study.Setting.A 625-bed tertiary care medical center.Patients.All patients who had an inpatient clinical culture positive for P. aeruginosa between January 1, 1999, and December 31, 2000.Results.From 1991 through 2000, the annual prevalence of imipenem resistance among P. aeruginosa isolates increased significantly (P<.001 by the χ2 test for trend). Among 879 patients infected with P. aeruginosa during 1999-2000, a total of 142 had imipenem-resistant P. aeruginosa infection (the case group), whereas 737 had imipenem-susceptible P. aeruginosa infection (the control group). The only independent risk factor for imipenem-resistant P. aeruginosa infection was prior fluoroquinolone use (adjusted odds ratio, 2.52 [95% confidence interval {CI}, 1.61-3.92]; P<.001). Compared with patients infected with imipenem-susceptible P. aeruginosa, patients infected with imipenem-resistant P. aeruginosa had longer subsequent hospitalization durations (15.5 days vs 9 days; P = .02) and greater hospital costs ($81,330 vs $48,381; P<.001). The mortality rate among patients infected with imipenem-resistant P. aeruginosa was 31.1%, compared with 16.7% for patients infected with imipenem-susceptible P. aeruginosa (relative risk, 1.86 [95% CI, 1.38-2.51]; P<.001). In multivariable analyses, there remained an independent association between infection with imipenem-resistant P. aeruginosa and mortality.Conclusions.The prevalence of imipenem resistance among P. aeruginosa strains has increased markedly in recent years and has had a significant impact on both clinical and economic outcomes. Our results suggest that curtailing use of other antibiotics (particularly fluoroquinolones) may be important in attempts to curb further emergence of imipenem resistance.
