Padua prediction score and IMPROVE score do predict in-hospital mortality in Internal Medicine patients.

Padua prediction score (PPS) and IMPROVE bleeding score are validated tools for venous thromboembolism (VTE) risk assessment recommended by guidelines, albeit not frequently used. Some data suggest that a positive PPS and IMPROVE score may be were associated with early mortality in Internal Medicine patients. Aim of the study was to characterize the predictive ability on mortality of the two scores using two different populations, respectively, as derivation and validation cohort. The derivation cohort consisted of 1956 Internal Medicine patients admitted to La Spezia Hospital in 2013. 399 Internal Medicine patients admitted to Carate Brianza Hospital in 2016 constituted the validation cohort. PPS and IMPROVE scores were applied to each patient using their validated cutoffs. Frequency of positive PPS and mortality were significantly higher in La Spezia patients. In the derivation cohort, the positivity of at least one of the two scores was associated with a significantly higher mortality compared to both negative scores. Similar results were observed in the validation cohort. In the derivation cohort, the sensitivity of a positive PPS score in predicting mortality was 0.97 (0.94, 0.98) but the specificity was 0.21 (0.19, 0.23), the negative likelihood ratio being 0.15. Sensitivity and specificity of a positive IMPROVE gave specular findings but the positive likelihood ratio was 2.19. The accuracy data in the validation cohort were in the same direction. Both PPS and IMPROVE are associated with in-hospital mortality but their additional predictive accuracy is modest. It is unlikely that both scores could be useful in clinical practice to predict death in hospitalized Internal Medicine patients.

Patterns and determinants of use of pharmacological therapies for intermittent claudication in PAD outpatients: results of the IDOMENEO study.

BACKGROUND: Peripheral arterial disease (PAD) usually presents with intermittent claudication (IC). The aim of the present study was to assess, in clinical practice, the pattern of use of pharmacological therapies for IC in stable PAD outpatients. METHODS: A propensity analysis was performed using data from the IDOMENEO study, an observational prospective multicenter cohort study. The association between any pharmacological symptomatic IC therapy with different variables was investigated using generalized linear mixed models with pharmacological therapy as response variable and binomial error. RESULTS: Study population: 213 patients, male sex 147 (69.0%), mean age 70.0±8.6 years. Only 36.6% was under pharmacological treatment for IC, being cilostazol the most used medication (21.6%). Univariate analysis showed a probability of a patient of being assigned to any pharmacological symptomatic IC therapy of 67.0% when Ankle-Brachial Index (ABI) <0.6 and 29.8% when ABI>0.6 (P=0.0048), and a propensity to avoid pharmacological treatment for patients with a high number of drugs to treat cardiovascular risk factors (probability of 55.2% for <4 drugs and 19.6% for >4 drugs, P=0.0317). Multivariate analysis confirmed a higher probability of assigning treatment for ABI<0.6 (P=0.0274), and a trend to a lower probability in patients under polypharmacy (>4 drugs: OR=0.13, P=0.0546). CONCLUSIONS: In clinical practice, only one third of stable outpatients with IC used symptomatic pharmacological therapy for IC. We found a propensity of clinicians to assign any symptomatic pharmacological IC therapy to patients with lower values of ABI and a propensity to avoid this kind of treatment in patients under polypharmacy.

Prognostic value of D-dimer in elderly patients with Pulmonary Embolism.

In a general population with acute Pulmonary Embolism (PE) elevated D-dimer concentrations associate with increased mortality. The aim of the study was to assess the ability of D-dimer to predict 30 and 90-days mortality in elderly patients with acute PE. Hemodynamically stable patients aged ≥65 years old with confirmed PE were included in this retrospective cohort study. A pulmonary computerized tomography angiography scan, D-dimer concentrations, simplified Pulmonary Embolism Severity Index (sPESI) variables and vital status were available for all patients. The study included 154 confirmed cases of PE (23.5 % of suspected), median age 79.1 years. D-dimer was higher in patients dead than in those alive at 30 (median 14,547 vs. 8340 ng/mL, p = 0.05) and 90 days (13,604 vs. 7973 ng/mL, p = 0.013). When adding D-dimer to sPESI, the discriminant capacity to predict mortality within 30 and 90 days was increased by 0.080 and 0.089, respectively. The contribution of D-dimer to the discriminating ability was NRI = 0.286 (95 % CI -0.198 to 0.770, p value: 0.247) at 30 days and NRI = 0.605 (95 % CI 0.223-0.988, p-value: 0.002) at 90 days.D-dimer concentration was associated with 30 and 90-days mortality and showed a higher discriminant capacity than sPESI alone to predict 90-days mortality. Adding D-dimer concentrations to sPESI score seems to improve its prognostic ability, supporting multivariable risk models as the best approach to estimate prognosis in elderly patients with PE.

A prospective multicentre study on the treatment of cardiovascular risk factors and claudication symptoms in patients with peripheral artery disease (the IDOMENEO study).

BACKGROUND: The objective of this prospective multicenter cohort study was to characterise the use of pharmacological and non-pharmacological treatment for cardiovascular disease (CVD) risk factors and intermittent claudication (IC) symptoms in clinical practice patients with peripheral artery disease (PAD), and to determine the care gap with international guidelines and evidence-based therapy. PATIENTS AND METHODS: From 2011 through 2013, participating centres enrolled consecutive patients with PAD of atherosclerotic, origin demonstrated by ultrasound, ankle brachial index (ABI) < 0.9 and symptoms of IC. A seven item grid was built for the assessment of care gap (percentage of patients eligible for a treatment who did not receive it). cerebrovascular disease or at least two CVD risk factors. Care gap was lower than 25 % for any method to stop smoking, lipid lowering agents, antiplatelet and/or anticoagulation therapy and any kind of exercise program; between 25% and 50% for ACE inhibitors/ angiotensin II antagonist therapy; between 50% and 75% for beta-blocker therapy; and higher than 75% for supervised exercise program and use of cilostazol. Patients with and without CADI cerebrovascular disease were differently treated with clopidogrel (27.3% and 4.8 %, p < 0.001), any antiplatelet/anticoagulant therapy (98.7% and 83.3 %, p <0.001) and beta-blockers (46.8% and 16.0%, p<0.001). RESULTS: All patients (232) presented at least one CVC risk factor, 90.2% at least two, and 91.5% had either established CAD or CONCLUSIONS: Many gaps with evidence-based recommendations are still present in the pattern of the use of pharmacological and non-pharmacological treatment for CVD risk factors and IC symptoms in clinical practice PAD patients.

Mortality at 30 and 90 days in elderly patients with pulmonary embolism: a retrospective cohort study.

Pulmonary Embolism (PE) incidence increases with age. Data on mortality and prognosis in elderly patients with suspected PE are lacking. (1) To assess 30- and 90-day mortality in subjects with PE from an elderly population seen in the emergency department (ED); (2) to test the prognostic accuracy of a simplified Pulmonary Embolism Severity Index (sPESI) coupled to a highly sensitive cardiac Troponin T (hs-cTnT) level. A retrospective cohort study was performed, including patients evaluated in the ED of Vimercate Hospital for clinically suspected PE from 2010 to 2012. Study population: n = 470, 63.4% women, mean age ± SD 73.06 ± 16.0 years, 40% aged ≥80 and 77.7% ≥65 years old, confirmed PE: 22.6% (106 cases). Within 30 and 90 days, mortality among patients with confirmed PE was 14.2% (8.8-22.0) and 20.8% (16.5-41.7). In subjects aged ≥80 years, 30-day mortality was 18.9% among patients with confirmed PE, and 12.6% among those with PE excluded (p = 0.317). Ninety-day mortality rates were 29.7 and 19.9%, respectively (p = 0.193). In patients with confirmed PE, Negative Predictive Value of sPESI was 94.1% (80.3-99.3) for 30 days and 88.2% (72.3-96.7) for 90-day mortality. Adding the hs-cTnT level to sPESI did not improve its performance. (1) In an elderly population referring to the ED with clinically suspected PE, mortality was high both in subjects with and without confirmed PE; (2) the ability of sPESI and hs-cTnT to predict PE mortality seems to be lower than reported in studies based on data from younger populations. Better risk stratification tools will be necessary to improve clinical management in this setting.

The efficacy of sulodexide in the prevention of postthrombotic syndrome.

AIM: The aim of this open, observational registry was to evaluate the effects of antithrombotic treatment on the development of postthrombotic syndrome (PTS): the effects of "standard management" (SM; according to International Union of Angiology guidelines) were compared to SM in association with sulodexide or aspirin. METHODS: Postthrombotic syndrome occurrence was observed in 3 nonparallel groups after deep venous thrombosis (DVT); the registry started after the end of the anticoagulation period. The target was to observe the occurrence of PTS in 5 years. Three possible options were suggested to the patients, and the patients and their caregivers defined the type of management. A group of 167 patients was involved in the SM with reevaluation every 6 months; the sulodexide group included 124 patients and the aspirin group included 48 patients. RESULTS: The 3 groups were clinically similar and comparable for age and sex distribution. Of the 167 patients in the SM group, 154 patients completed 60 months of follow-up. The percentage of patients with PTS in the SM group ranged from 14.9% (1 year after the end of anticoagulation) to 19.5% (60 months). In the nonparallel group using sulodexide (124 comparable patients at inclusion; 115 at 60 months), the percentage of PTS was variable from 8.8% (1 year after anticoagulants) to 12.17% at 60 months. These percentages are significantly lower than those observed with SM. In the nonparallel aspirin group (48 patients at inclusion and 34 at 54 months), there was a PTS incidence of 23.5% at 54 months (vs 12.17% in the sulodexide group and 18.23% in the SM group). The incidence of PTS was significantly higher in comparison with the other 2 groups. The incidence of PTS was lower in the sulodexide group in comparison with the 2 other groups. CONCLUSIONS: Sulodexide administration after DVT appears to be effective in preventing PTS in association with recommended management and a number of recurrent DVTs. Modalities of treatment, dosages, and timing of administration should be explored in more comprehensive and complete studies.

Risk of venous thromboembolism in patients nursed at home or in long-term care residential facilities.

Background. This study investigated the prevalence of and impact of risk factors for deep venous thrombosis (DVT) in patients with chronic diseases, bedridden or with greatly limited mobility, cared for at home or in long-term residential facilities. Methods. We enrolled 221 chronically ill patients, all over 18 years old, markedly or totally immobile, at home or in long-term care facilities. They were screened at the bedside by simplified compression ultrasound. Results. The prevalence of asymptomatic proximal DVT was 18% (95% CI 13-24%); there were no cases of symptomatic DVT or pulmonary embolism. The best model with at most four risk factors included: previous VTE, time of onset of reduced mobility, long-term residential care as opposed to home care and causes of reduced mobility. The risk of DVT for patients with reduced mobility due to cognitive impairment was about half that of patients with cognitive impairment/dementia. Conclusions. This is a first estimate of the prevalence of DVT among bedridden or low-mobility patients. Some of the risk factors that came to light, such as home care as opposed to long-term residential care and cognitive deficit as causes of reduced mobility, are not among those usually observed in acutely ill patients.

Venous thromboembolism in medical patients treated in the setting of primary care: a nationwide case-control study in Italy.

OBJECTIVES: The risk of venous thrombotic events (VTE) among medical outpatients is still not clear and it remains to be clarified whether medical diseases involve the same risk if managed at home or in hospital. The aim of this study was to evaluate in the setting of outpatient family medicine the relationship between VTE and medical conditions known to be at risk during a hospital stay. DESIGN AND SETTING: The study involved a nationwide retrospective observation according to a nested case-control method; 400 general practitioners throughout Italy constituted the network for data collection. Between 2001 and 2004, all cases recorded as having VTE were entered; ten control patients without VTE, matched by sex, physician, and age, were selected from the database for each case. RESULTS: The eligible population comprised 372,000 patients and 1,624 incident VTE were recorded. Univariate analysis indicated hospitalization (OR 5.02; 95% CI 4.01-6.29), cancer (OR 3.06; 95% CI 2.47-3.79), acute infectious disease (OR 2.93; 95% CI 1.94-4.43), neurological disease (OR 2.60; 95% CI 1.56-4.33), congestive heart failure (CHF) (OR 2.48; 95% CI 1.68-3.69), paralysis (OR 1.87; 95% CI 1.51-2.32), COPD (OR 1.58; 95% CI 1.29-1.95), stroke (OR 1.62; 95% CI 1.24-2.12), superficial venous thrombosis (OR 1.51; 95% CI 1.11-2.04, and rheumatic diseases (OR 1.49; 95% CI 1.28-1.74) as significantly associated with an increased risk for VTE. After adjustment, only transient or definitive paralysis, cancer, acute infectious disease, congestive heart failure, neurological diseases, and previous hospitalization remained associated. CONCLUSIONS: This large study indicates that VTE outpatients seen by general practitioners in Italy have a high prevalence of the same medical diseases associated with VTE among patients treated in hospital.

Agenesis of the right internal carotid artery and Klippel-Feil syndrome: case report.

STUDY DESIGN: Case report. OBJECTIVE: To describe the case of a Klippel-Feil anomaly associated with carotid agenesis. SUMMARY OF BACKGROUND DATA: Klippel-Feil anomaly is a spinal malformation characterized by fusion of the cervical vertebrae. Four subtypes have been identified for this congenital disorder with different severity of vertebral fusion and different extra-axial anomalies. Most cases are sporadic, although autosomal dominant and autosomal recessive cases are recognized. It can cause neurologic disorders and is associated to vascular abnormalities. However, agenesis of internal carotid and Klippel-Feil syndrome is an unusual association. METHODS: A 49-year-old woman came to our attention for recurrent transitory ischemic attacks presenting with weakness of left limbs associated with sensory abnormalities. Neurologic examination revealed mild left limb weakness and tactile hypoesthesia. RESULTS: Brain magnetic resonance (MR) and MR angiography demonstrated absence of the right internal carotid and the middle right cerebral artery was filled from the basilar artery. Fusion of vertebral bodies was documented at MR and confirmed at spinal CT scan. The day after the admission the neurologic examination became normal. Ticlopidine was then started. CONCLUSION: Literature of vascular abnormalities in association with Klippel-Feil syndrome takes the form of anecdotal reports. Aortic coarctation, vertebral artery dissection, aneurysms, persistent trigeminal artery, and abnormal origin of internal carotid are described. An unusual association of carotid internal agenesis and Klippel-Feil syndrome is reported with a literature review.

D-dimer before chemotherapy might predict venous thromboembolism.

To see whether D-Dimer levels can identifying patients at high risk of venous thrombotic events and establish the best benefit/risk-of-bleeding ratio. Current guidelines do not recommend routine prophylaxis against venous thromboembolism (VTE) in cancer patients receiving chemotherapy, but the risk increases about 6.5-fold because of this treatment. D-dimer was measured at baseline in 124 cancer patients scheduled for their first chemotherapy. VTE events, including symptomatic episodes of deep vein thrombosis or pulmonary embolism or both, were recorded during the first 6 months of therapy, and asymptomatic deep vein thrombosis was revealed by compression ultrasonography at baseline and after 90 and 180 days. During follow-up, there were 11 episodes of VTE (8.9%). Mean D-dimer values were higher in patients with VTE (2195 +/- 1382 vs. 695 +/- 1039 ng/ml, (P < 0.001). On grouping D-dimer values in tertiles, only 2.4% (confidence interval, 0.9-5.7%) in the first (<262 ng/ml) and second tertiles (262-650 ng/ml) suffered a deep vein thrombosis/pulmonary embolism event as compared with 22% (confidence interval, 9-34%) in the third (>650 ng/dl) (P = 0.003). The VTE-free interval was significantly shorter in the third tertile than in the first (P = 0.0218, log-rank test; relative risk for third vs. first tertile, 11.0; 95% confidence interval, 1.4-81.3; P = 0.0033). Multivariate analysis found that only baseline D-dimer concentrations were correlated with the subsequent development of VTE. Baseline D-dimer values in cancer patients scheduled for chemotherapy might be used to select those at low risk of VTE, most likely to be safe without prophylaxis.

Attitudes to prescribing compression stockings for patients with acute DVT: the MASTER registry.

UNLABELLED: Compression therapy is still not widely used for patients with deep vein thrombosis (DVT). This report provides information on Italian doctors' use of elastic stockings (ES) after acute DVT and identifies some predictors of prescription. MATERIAL AND METHODS: The MASTER multicenter registry collected information about clinical characteristics and management of patients with venous thromboembolism (VTE). In patients with objectively confirmed acute VTE, information about clinical presentation, diagnostic methods, temporary and permanent risk factors, pre-event prophylaxis and treatment, including ES prescription, were captured by an electronic data network at the time of the index event. RESULTS: Of 2119 patients enrolled, 1913 had DVT, 1772 in the legs; 1277 were prescribed ES at hospital discharge. The following conditions were associated with more frequent prescription: edema, in-hospital management, known thrombophilia; younger age. In multivariate analysis these factors all remained significantly associated with more frequent use of ES. CONCLUSIONS: Italian clinicians' attitudes to prescribing ES still appear suboptimal. Special attention is needed for patients treated at home, where organizational problems can interfere with the use of ES.

The impact of antithrombotic prophylaxis on infectious complications in cancer patients with central venous catheters: an observational study.

Infections in cancer patients after implantation of a central venous device (CVD) are not infrequent and are potentially serious. The possibility of limiting this complication with antithrombotic drugs is still debated. For this observational study, we recorded the routine management of CVD in cancer patients in 18 oncology centers in Lombardy (northern Italy), assessing the effect of antithrombotic prophylaxis on catheter-related infections. Out of 1410 patients enrolled, 451 received antithrombotic prophylaxis continuously after implantation of the central line. During a median follow-up of 30 months, 57 catheter-related infections were reported in the 1390 patients seen at least once at follow-up visits (4.1% of the whole series), giving an overall incidence of 0.10 infections per 1000 catheter days. This complication was significantly more frequent among patients with an indwelling central venous catheter, or peripherally inserted catheter, than among those with a port device, and the group not given antithrombotic prophylaxis had 0.14 infective complications/1000 CVD days compared with 0.05/1000 CVD days (odds ratio 2.4; 95% confidence interval 1.7-5.0) for those treated. Antithrombotic prophylaxis protected against infections at the catheter exit site and track but not against systemic infections. Confirming earlier evidence, this study found a reduction in catheter-related infections in patients given antithrombotic prophylaxis. However, this reduction, reflecting local infections, seems unlikely to be one of the mechanisms explaining the lower mortality among our patients treated with anticoagulants.

Efficacy of elastic compression stockings used early or after resolution of the edema on recanalization after deep venous thrombosis: the COM.PRE Trial.

Elastic compression stockings are useful for preventing post-thrombotic syndrome after deep venous thrombosis (DVT). Less is known about their effects on thrombus recanalization and the optimal timing for starting compression. This study investigated whether compression applied early was more effective than when started 2 weeks after DVT. Seventy-three patients with DVT were randomly assigned to elastic compression hosiery starting either immediately after diagnosis or 2 weeks later. After 14 and 90 days the residual thrombus was measured by compression ultrasonography, and venous patency and any pathological reflux were recorded. There were significantly more recanalized venous segments in the group treated with early compression. Recanalization of popliteal DVT veins, expressed as the reduction of vein diameter, was also better in the early compression group than controls (day 14, 6.5 +/- 3 versus 5 +/- 2 mm, P = 0.035; day 90, 3.7 +/- 3 versus 2.1 +/- 1.7 mm; P = 0.014). On day 14 the mean score for popliteal patency was significantly better for the early compression patients (1.0 +/- 0.6 versus 1.5 +/- 0.5, P = 0.0015). In conclusion, elastic compression applied immediately at diagnosis of DVT was safe and effective on the surrogate end-points investigated in this study. Longer follow-up in larger series is needed to verify the patterns of recurrence of DVT and post-thrombotic syndrome.
