Abstract:
For a given bivariate Lévy process (Ut, Lt)t≥0, distributional properties of the stationary solutions of the stochastic differential equation dVt = Vt-dUt + dLt are analysed. In particular, the expectation and autocorrelation function are obtained in terms of the process (U, L) and in several cases of interest the tail behavior is described. In the case where U has jumps of size −1, necessary and sufficient conditions for the law of the solutions to be (absolutely) continuous are given.

Abstract:
Abstract Objective The aim of the study is to investigate the correlations among serum homocysteine (Hcy), D-dimer, and the risk of developing deep venous thrombosis (DVT) of the lower extremities in patients who underwent operation for lower limb fracture. Methods Seventy-five cases who underwent operation for lower limb fracture were included and further divided into DVT group (n = 26) and control group (n = 49) based on post-DVT diagnostic criteria. The serum Hcy and D-dimer were examined 48 h after operation. The serum Hcy and D-dimer levels were compared between the two groups. The correlation between serum Hcy and D-dimer was investigated by the Pearson correlation test. The receiver-operating characteristic (ROC) curve was applied to evaluate the diagnostic performance of serum Hcy and D-dimer as serological markers for DVT. Results The serum Hcy concentrations were 11.96 ± 3.98 μmol/L and 7.92 ± 3.27 μmol/L for DVT and control groups, respectively, with statistical difference (t = 4.72, P < 0.01). The serum D-dimer in the DVT group was significantly higher than that of the control group (8.99 ± 4.50 vs 1.70 ± 2.11) μg/mL with statistical difference (t = 9.56, P < 0.01). Line regression analysis indicated that serum Hcy was positively correlated with serum D-dimer concentration and can be demonstrated by the equation of Y = 0.6651*X + 1.036 for the DVT group. Using serum Hcy as the biomarker for predicting DVT, the prediction sensitivity and specificity were 76.92 and 71.44%, respectively, with the AUC of 0.7804 under the cut-point of 9.54 μmol/L. For serum D-dimer, the prediction sensitivity and specificity were 96.15 and 73.47%, respectively, with the area under the ROC (AUC) of 0.9455 under the cut-point of 1.66 μg/mL. Conclusion Serum Hcy was significantly elevated in DTV patients, and hence, it can be applied as a serological marker for DVT prediction in patients who underwent operation for lower limb fracture. However, the DVT prediction performance of serum Hcy was inferior to D-dimer especially for diagnostic sensitivity.

Abstract:
Background and Purpose. Shorter door-to-needle time (DNT) is associated with a better outcome in acute ischemic stroke (AIS) patients who accept intravenous thrombolysis. We aimed to explore whether triage nurse-activated emergency evaluation would reduce DNT compared with doctor-activated emergency evaluation in AIS patients treated with intravenous thrombolysis who failed to use emergency medical services (EMSs). Methods. This was a retrospective analysis in a general hospital emergency department in Beijing, China. 212 adult AIS patients treated with thrombolysis who failed to use EMSs were included. In addition to DNT, door-to-vein open time (DVT), door-to-blood sample deliver time (DBT), and 7-day NIHSS scores were evaluated. Results. 137 (64.6%) patients were in the triage nurse-activated group and 75 (35.4%) patients were in the doctor-activated group. The DNT of the triage nurse-activated group was significantly reduced compared with the doctor-activated group (28 (26, 32.5) min vs. 30 (28, 40) min, p = 0.001 ). DNT less than 45 min was seen in 95.6% of patients in the triage nurse-activated group and 84% of patients in the doctor-activated group ( p = 0.011 , OR 3.972, 95% CI 1.375–11.477). In addition, DVT (7 (4, 10) min vs. 8 (5, 12) min, P = 0.025 ) and DBT (15 (13, 21) min vs. 19 (15, 26) min, p = 0.001 ) of the triage nurse-activated group were also shorter than those of the doctor-activated group ( p < 0.05 ). The 7-day NIHSS scores were not statistically different between the two groups. Conclusions. Triage nurse-activated urgent emergency evaluation could reduce the door-to-needle time, which provides a feasible opportunity to optimize the emergency department service for AIS patients who failed to use emergency medical services.

Abstract:
Patients with pulmonary embolism (PE) may have symptomatic or asymptomatic concomitant deep vein thrombosis (DVT). The reported prevalence of PE-associated DVT is variable, and thus, the utility of routine testing is controversial. The aim of our study was to analyze the prevalence of DVT and the factors associated with proximal DVT/whole-leg DVT in patients with symptomatic PE. In 428 consecutive patients (mean age: 59 ± 16.4 years; 52.3% men), we performed clinical examination and complete bilateral compression ultrasound and ascertained medical history and risk factors for DVT/PE. χ2 and t tests were used. Deep vein thrombosis was found in 70.6%; proximal DVT in 49.5%. Sensitivity/specificity of DVT symptoms was 42.7%/93.7% for whole-leg DVT and 47.6%/83.3% for proximal DVT. Male gender significantly prevailed among those with whole-leg DVT and with proximal DVT (58.9% and 61.8%). Active malignancy was significantly more frequent in the patients with proximal DVT than without proximal DVT (10.4% vs 3.7%). In conclusion, the prevalence of PE-associated DVT is quite high but clinical diagnosis is unreliable. In our group, male gender and active malignancy were significantly associated with the presence of concomitant proximal DVT.

Abstract:
SummaryThere is a lack of consensus on the value of detecting and treating symptomatic isolated distal deep-vein thrombosis (DVT) of the lower limbs. In our study, we compared the risk factors and outcomes in patients with isolated symptomatic distal DVT with those with proximal symptomatic DVT. We analysed the data of patients with objectively confirmed symptomatic isolated DVT enrolled in the national (France), multicenter, prospective OPTIMEV study.This sub-study outcomes were recurrent venous thromboembolism, major bleeding and death at three months. Among the 6141 patients with suspicion of isolated DVT included between November 2004 and January 2006, DVT was confirmed in 1643 patients (26.8%). Isolated distal DVT was more frequent than proximal DVT (56.8% vs. 43.2%, respectively; p=0.01). Isolated distal DVT was significantly more often associated with transient risk factors (recent surgery, recent plaster immobilisation, recent travel), whereas proximal DVT was significantly more associated with more chronic states (active cancer, congestive heart failure or respiratory insufficiency, age >75 years). Most patients (96.8%) with isolated distal DVT received anticoagulant therapies.There was no difference in the percentage of recurrent venous thromboembolism and major bleeding in patients with proximal DVT and isolated distal DVT. However, the mortality rate was significantly higher (p<0.01) in patients with proximal DVT (8.0%) than in those with isolated distal DVT (4.4%). Symptomatic isolated distal DVT differs from symptomatic proximal DVT both in terms of risk factors and clinical outcome. Whether these differences should influence the clinical management of these two events remains to be determined.

Abstract:
Objectives: To evaluate the effectiveness of LMWH prophylaxis for DVT in high risk patients after general surgery. Study design: Randomized controlled study. Setting: Surgical Unit-IV, District Head Quarters Hospital, Faisalabad. Period: From March 2009 to August 2009. Patients and Methods: Sixty patients in the LMWH group were given perioperative enoxaparin (Clexane) as prophylaxis while compression stockings were used in another control group comprised of 60 patients. At 5th postoperative day, Doppler study was performed to detect DVT in both groups. Categorical data were analyzed for significance using Chi square test through SPSS. Results: There were significant difference in age factor, history of DVT, Medical factor, surgical trauma factor and interpretation on the basis of points. However, there is non significant difference between LMWH group and control group for chemoprophylasis. Conclusions: LMWH administration is effective for the prevention of venous thromboembolism in high risk patients and its practice should be the standard of care in the practice of surgery.

Abstract:
Venous thromboembolism (VTE) encompasses both deep vein thrombosis (DVT) and pulmonary embolism (PE).1,2 Factors such as venous stasis, vascular injury, hypercoagulability and major orthopaedic surgery such as hip/ knee replacement or hip fracture surgery increases the risk for thrombosis. Currently there is limited information on the incidence and risk of VTE following ankle fracture surgery and the economic impact on the use of prophylaxis for the prevention of VTE in these patients. Chapter one of this thesis provides a comprehensive literature review highlighting the epidemiology, risk factors, prophylactic modalities used and complications in both medical and surgical patients for the prevention of VTE. Chapter two is a retrospective study that examines this area, in particular, practice patterns in VTE prevention both in-hospital and beyond hospitalisation following ankle fracture surgery. These results showed that most of these patients received low molecular weight heparin (LMWH) and that the overall in-hospital VTE incidence was 2.9% (95% CI: 1.3 - 4.4). There was a 1.5-fold increase risk of VTE at three months post hospitalisation (4.3% (95% CI: 2.3 - 6.2), bleeding rates were low and there were no major complications. This led to a systematic literature review for chapter three evaluating the economic impact with use of pharmacological prophylaxis in major orthopaedic surgery for VTE prevention as well as complications and treatment costs. These results highlighted economic benefits with the use of LMWH compared to difference in healthcare systems. The first two chapters emphasise the importance of immobility for the risk of thrombosis. This is discussed in chapter four together with a summary of the main findings, gaps and future directions. The need to explore the importance of immobility on DVT risk led to a protocol development and ethics approval for the evaluation of the rates of DVT in diabetic foot ulcer patients with total contact casts.

Abstract:
Clinically, it is difficult to predict deep vein thrombosis (DVT), but the in vitro saline dilution test using the Thrombo-elastograph (TEG) is reported to identify the risk for individual patients [1]. The Biobridge Impedance Clotting Time (ICT) is more sensitive and reproducible than the TEG [2], and we therefore studied 33 patients undergoing elective laparotomy to see if pre-operative saline dilution tests using both the TEG and ICT predicted post-operative DVTs. Post-operatively, both legs were scanned daily for 7 days using 125I Fibrinogen to detect DVTs.The mean age of the patients was 65.7±2.4 years and 17 had malignant disease. In this clinically high risk group, 24 developed a DVT.Fifty-one percent were predicted correctly by TEG. The ICT was significantly better as a predictor with 79% of all patients correctly predicted (p<0.01).The saline dilution test using the ICT is a significant improvement on the TEG, and may enable us to tailor DVT prophylaxis policy to each patient’s specific requirements.Heather BP, Jennings SA, Greenhalgh RM.

Abstract:
Dehydroepiandrosterone sulphate (DHEAS) is a major secretory product of the human adrenal gland. Its precise functions are uncertain, but it has been postulated as a discriminator of life expectancy and aging. We have previously reported significantly lower plasma levels of DHEAS pre- and postoperatively in men developing DVT after major abdominal surgery, as compared to patients who remained free of DVT. Recent data suggest that the DHEAS concentration is also independently and inversely related to death from cardiovascular disease in men over 50 years of age. We here report data on preoperative plasma concentrations of DHEAS (measured with RIA) in 96 patients over 40 years of age, who underwent major abdominal surgery, and correlated the result to the development of postoperative DVT as diagnosed by the 125I-fibrinogen uptake test.Thirty patients (31%) developed postoperative DVT during the first ten postoperative days. The plasma levels of DHEAS were significantly lower in the patients with postoperative DVT compared to those without (median 1.95 umol/1; Q1−Q3, 1.30−3.00 vs. median 3.35 umol/1; Q1−Q3 1.60−4.70; p < 0.02). Ninety per cent of the patients who developed postoperative DVT had a DHEAS value lower than 3.9 umol/1, while 45 % of the patients who remained free of DVT had a DHEAS value higher than 3.9 umol/1.In conclusion, the data suggest that a low preoperative value of DHEAS predisposes the development of postoperative DVT in patients undergoing major abdominal surgery. It seems like the DHEAS concentration in plasma can be a valuable factor in a predictive index for postoperative DVT in those patients.

Abstract:
A semi-quantitative RNP using 99Technetium macroaggregated albumin for the evaluation and follow-up of DVT and CVI has been developed. Values were assigned to the deep veins of the calf, knee, tigh and pelvis based upon the localization and the characteristics of the images obtained: stasis, hot spots and collateral circulation. A maximum score of 18 reflected complete thrombosis of all 4 segments. 208 patients (mean age 53.7 years, range 18-92), 161 of whom had a proven risk factor for DVT were studied. 99Technetium was injected into the dorsal foot vein of 407 limbs with appropriate tourniquets and early and late imaging of the limbs, pelvis and lungs was performed. In 48 patients, 83 limbs, X-ray contrast phlebography (CP) was also done. The mean RNP score was 4.1 units (range 0.4-18) and higher in the left than the right lower limb. It was mostly high in patients with proximal recurrent DVT or in DVT superimposed on CVI. The score was easy to follow and helpful in the assessment of the extent of DVT. It was particularly helpful in 3 instances. 1) Assessment of venous patency following anticoagulant therapy. 2) Estimation of recurrent DVT. 3) Differentiation of recent DVT from venous insufficiency. Overall RNP method had a sensitivity of 87.6%, a specificity of 54% and an accuracy of 64.8%. The sensitivity was similar in above & below-knee thrombi. Yet the specificity was higher in above-knee thrombi. The highest accuracy (87.3%) was observed in pelvic and groin thrombi. The distribution of thrombi on CP was 19% below the knee, 31% above it and 50% both above and below the knee. Pulmonary embolism (PE) was initially observed in 54 patients (26%) with no clinical evidence of DVT and therefore untreated. This high level is most probably related to the high incidence of proximal DVT in the patients. 181 patients were treated with heparin & coumadin and the RNP score was decreased to 3.6 units (range 0.4-8.8). PE occurred during treatment in 11 (6.1%) and recurrent DVT in 16 (8.8%) patients. CVI was observed in 23 patients before treatment and in another 24 patients (13.2%) after treatment. These results indicate that the RNP method is a simple, semi-quantitative and useful technique for the evaluation and follow-up of DVT and CVI. It is most helpful in the assessment of the extent of DVT. It is also a rapid, noninvasive and cost effective techniaue.

Abstract:
Postoperative deep vein thromboisis(DVT) is a frequent complication following total hip (THR) or knee (TKR)replacement but no test has been devised to identify specific patientswho will develop DVT. Because conventional prophylaxis does not significantly reduce the incidence of DVT, monitoring is widely used to detect evolving thrombosis. More intense anticoagulation (adjusted dose heparin,two step warfarin) may be effective but requires laboratory tests and carries increased risk of bleeding. Itwould be an economic and medical advantage to restrict prophylaxis and monitoring to patients who will develop DVT. Based on observations in a canine model of THR, we developed andtested a method that shows promise of being able toidentify, intraoperatively, patients who will develop DVT.In the canine model we found characteristic venous lesions (gaping tears through endothelium and basementmembrane, localized to confluences,selectively infiltrated with platelets and leukocytes). Incidence of lesions correlated with intraoperative venodilation, measured by a modified ultrasound scanner. Lesionsmight serve as sites for initiationand anchorage of thrombi. Diagnostic ultrasound was used to monitor cephalic vein diameter in 25 THR patients and 12 TKR patients. In THR patients, 1 of 9 patients with venodilation of 6-16% developed DVT. At 21-57% venodilation 12 of 12 THR patients developed thrombi. In the intermediate range of venodilation (19%,20%), 2 of 4 patients developedDVT. In 12 TKR patients, 10 had venodilation of 0-16% and none developedDVT in the non-operated leg. In patients with 22% and 55% venodilation,one did and one did not develop DVT in the non-operated leg (expectedfrcxn equal distribution between legs in THR patients).DVT in the operated leg did not correlate with venodilation. We suggest that in THR patients substances released at the operative site circulate briefly, causing venous dilation. In TKR patients the tourniquet prevented substances from being circulated, reducing venodilation and DVT in the non-operated leg. Proximitv of surgicalwound to calf veins and tourniquet pressure mav have contributed to DVT in the operated leg.

Abstract:
As a blood marker of endothelium, we investigated the seric activity of Angiotensin Converting Enzyme (ACE) at rest and after stimulation either by local venostasis or dDAVP infusion. dDAVP did not induce any significant change in ACE contrarily to venostasis. Searching for an endothelial abnormality implicated in the genesis of Deep Vein Thrombosis (DVT) we applied the local venostasis test to patients affected by recurrent DVT. Patients, divided in 3 groups (group I : documented history of recurrent DVT, group II : only one DVT or recurrent superficial venous thrombosis, group III : history of arterial thrombo embolism), and controls were screened for ACE as well as for plasmatic fibrinolytic activity and von Willebrand factor (vWF) level. Two types of abnormalities of seric ACE activity were found : low basal level in group I and low response to venostasis in groups I and III : group II did not differ from controls. This suggests an endothelial lesion participating to the etiology of some recurrent DVT and supports the measurement of seric ACE to discriminate some patients at high risk of DVT. Measures of fibrinolytic and ACE activities are not redundant since the two types of ACE abnormalities were not individually encountered in the same patients and were independent from abnormalities of the fibrinolytic system

Abstract:
Plasma protein C inactivates the activated coagulation factors V and VIII. The assay of protein C is important, because a protein C deficiency is associated with a thrombotic tendency. We therefore evaluated 5 commercial assays in 49 normal volunteers, 48 patients suspected of deep vein thrombosis (DVT) of the leg but with negative impedance plethysmography (IPG), and 52 patients with DVT proven by IPG. The assays were rocket electrophoresis (Merz and Dade antibody), ELISA (Boehringer Mannheim), 2 chromogenic activity assays (Behringwerke and Kabi) and a clotting assay (Behringwerke). Coumarin therapy was used by 13 DVT positive, and 3 DVT negative patients. Results are presented in the table.TABLE: In correlation 1 and 2, the assay results all non-coumarin treated individuals (n = 133) were compared with rocket electrophoresis and ELISA resp.In the non-coumarin treated patients, both in the DVT positive and in the DVT negative patient group one protein C deficiency was detected by all assays.Based upon the large assay VC (ROCKET) and normal range (B. CLOT), and poor correlation of the assays with the ELISA (ROCKET, B. CLOT) we conclude that the ELISA, B.CHROM and K.CHROM are to be preferred. However, as B.CHROM does not need a plasma absorption step it is somewhat preferable for activity assays.

In a prospective studie 129 patients with hip fracture surgery under LDH-prophylaxis (3x5000 U Na-heparinat) were examined in order to find an answer tothe question, if there is a correlation between inhibitor activity, parameters of fibrinolysis, plasma heparin activity and the incidence of DVT.100 patients with ascending phlebography on day 7 to9 post op. were taken into final consideration (blood collection on admission and on day 1, 2, 4, 7 after surgery):1)Incidence of DVT : 17 %.2)Inhibitors: No difference between patients with and without DVT with respect to AT III activity and prot. C concentration ( prot. C activity in progress).3)Fibrinolysis: Elevated levels of DD-fragment (x = 1 780 mg/ml), t-PA Inhibitor (x = 31 AU) and fibrinogen (417 rng/dl) before operation due to preceding trauma. No significant difference between t-PA, t-PA inhibitor and antiplasmin with respect to DVT. Whileplasminogen concent was significantly increased in patients with DVT on day 4 and 7, DD-fragments had lower values on day 7 (x = 1395 / x = 2140 ng/ml).4)Heparin effect: Plasma heparin activity was assesed by an amidolytic anti ll^assay. Although plasmaticheparin action only represents one aspect of thromboprophylactic heparin-activity, there is an obvious difference between patients with and without DVT withrespect to plasmatic heparin activity( p <0.005).

Abstract:
The diagnosis of deep vein thrombosis (DVT) by clinical signs and symptoms is unreliable, but contrast venography is expensive and invasive. Therefore, the use of non-invasive methods to detect DVT have become en vogue, of which impedance plethysmography (IPG), either in combination with 125x fibrinogen leg scanning or performed serially as a single test, have been demonstrated to be a safe and effective alternative. Since the principle of IPG is based on the measurement of venous outflow obstruction due to intravascular thrombus and since the aim of anticoagulant treatment is to facilitate recanalisation one might expect a gradual normalisation of IPG in the majority of patients. This information is important for patients presenting with recurrent signs and symptoms. If the IPG has normalized prior to presentation it is possible to separate complaints due to recurrent DVT from post phlebitic syndrome. In this prospective trial we studied 161 consecutive outpatients with abnormal IPG and venography proven DVT three monthly during one year to determine the rate of normalization and to estimate the utility of IPG testing in patients with recurrent symptomatic DVT. The IPG test had normalized in 101 of 151 patients (67%) by three months, in 126 of 148 (85%) after six months, in 133 of 145 (92%) while after one year 139 of 146 (95%) had their IPG normalized. During the one year follow-up 35 of the 161 study patients (23%) returned with recurrent symptoms. Of these 31 had normal IPG tests prior to the visit. In 18 patients IPG remained normal at repeat testing. In 13 patients IPG became again abnormal (venography showed acute on chronic DVT in 10 patients while 3 patients showed no acute DVT). It is concluded that a 95% normalization of IPG occurs and that IPG is useful in the management of recurrent symptoms.

Abstract:
Review question / Objective: The systematic review aim to provide synthesised and appraised evidence to assess the bleeding risk of anticoagulant therapy in patients with advanced cancer in palliative care settings. Condition being studied: Cancer is a recognized risk factor for venous thromboembolism (VTE). The main forms of thromboembolic disease include pulmonary embolism (PE) and deep vein thrombosis (DVT). Given their diagnosis and often poor physical status, patients with advanced cancer are at particularly high risk of developing VTE, resulting in reduced activity levels or even immobility. The exact incidence and prevalence of VTE in the population of cancer patients receiving hospice or palliative care has not been well investigated and few reports are available. Clinical studies have not yet determined whether such patients benefit from anticoagulant therapy and whether there is an increased risk of bleeding and death.
