Background: Top-down (TD) strategy with frontline infliximab proved to be more effective than the traditional step-up (SU) approach in newly diagnosed luminal moderate-to-severe CD patients. However, the considerable cost of infliximab calls its universal use as frontline treatment into question. The aim of this study is to evaluate the cost-effectiveness of the TD approach using a Markov decision model. Methods: Four states were modelled, namely step 1, step 2, step 3 and death. The first three steps were in TD infliximab induction plus azathioprine, infliximab rechallenge plus azathioprine and steroids plus azathioprine, and in SU steroid induction, azathioprine plus steroid rechallenge and infliximab plus azathioprine. Each health state lasted 1 month. The time horizon of the model was 5 years. Transition probabilities and quality of life were estimated from a randomised trial. First- and second-order sensitivity analyses were done to test the robustness of the results. Results: At baseline analysis, TD improved quality-adjusted life expectancy from 3.76 to 3.90 quality-adjusted life years (QALYs), that is, 0.14 QALYs, while allowing a saving of €773, proving dominant when compared to SU. TD was cost-saving in 66 % of the Monte Carlo simulations and cost <€20,000/QALY in 84 %. At sensitivity analysis the most significant variables were infliximab cost and time horizon: doubling infliximab cost (€1,000 per 100 mg vial) resulted in an incremental cost-utility ratio of €12,114/QALY. Conclusions: TD is a cost-effective treatment in newly diagnosed CD patients with luminal moderate-to-severe disease, and sensitivity analysis showed the result to be robust. © 2012 Springer-Verlag.

Neurological diseases which constituted traditionally obstacles to artistic creation can, in the case of migraine, be transformed by the artists into a source of inspiration and artistic production. These phenomena represent a chapter of a broader embryonic neurobiology of painting. © 2014 Springer-Verlag. Source

Alzheimer's disease (AD) is the commonest form of dementia in the elderly, characterized by memory dysfunction, loss of lexical access, spatial and temporal disorientation, and impaired judgment. A growing body of scientific literature addresses the implication of dietary habits in the pathogenesis of AD. This review reports recent findings concerning the modulation of AD development by dietary lipids, in animals and humans, focusing on the pathogenetic role of lipid oxidation products. Oxidative breakdown products of ω-6 polyunsaturated fatty acids (ω-6 PUFAs), and cholesterol oxidation products (oxysterols), might play a role in favoring β-amyloid deposition, a hallmark of AD's onset and progression. Conversely, ω-3 PUFAs appear to contribute to preventing and treating AD. However, high concentrations of ω-3 PUFAs can also produce oxidized derivatives reacting with important functions of nervous cells. Thus, altered balances between cholesterol and oxysterols, and between ω-3 and ω-6 PUFAs must be considered in AD's pathophysiology. The use of a diet with an appropriate ω-3/ω-6 PUFA ratio, rich in healthy oils, fish and antioxidants, such as flavonoids, but low in cholesterol-containing foods, can be a beneficial component in the clinical strategies of prevention of AD. © 2011 WILEY-VCH Verlag GmbH & Co.

Introduction: Since positive blood cultures are uncommon in patients with nosocomial pneumonia (NP), the responsible pathogens are usually isolated from respiratory samples. Studies on bacteremia associated with hospital-acquired pneumonia (HAP) have reported fatality rates of up to 50%. The purpose of the study is to compare risk factors, pathogens and outcomes between bacteremic nosocomial pneumonia (B-NP) and nonbacteremic nosocomial pneumonia (NB-NP) episodes.Methods: This is a prospective, observational and multicenter study (27 intensive care units in nine European countries). Consecutive patients requiring invasive mechanical ventilation for an admission diagnosis of pneumonia or on mechanical ventilation for > 48 hours irrespective of admission diagnosis were recruited.Results: A total of 2,436 patients were evaluated; 689 intubated patients presented with NP, 224 of them developed HAP and 465 developed ventilation-acquired pneumonia. Blood samples were extracted in 479 (69.5%) patients, 70 (14.6%) being positive. B-NP patients had higher Simplified Acute Physiology Score (SAPS) II score (51.5 ± 19.8 vs. 46.6 ± 17.5, P = 0.03) and were more frequently medical patients (77.1% vs. 60.4%, P = 0.01). Mortality in the intensive care unit was higher in B-NP patients compared with NB-NP patients (57.1% vs. 33%, P < 0.001). B-NP patients had a more prolonged mean intensive care unit length of stay after pneumonia onset than NB-NP patients (28.5 ± 30.6 vs. 20.5 ± 17.1 days, P = 0.03). Logistic regression analysis confirmed that medical patients (odds ratio (OR) = 5.72, 95% confidence interval (CI) = 1.93 to 16.99, P = 0.002), methicillin-resistant Staphylococcus aureus (MRSA) etiology (OR = 3.42, 95% CI = 1.57 to 5.81, P = 0.01), Acinetobacter baumannii etiology (OR = 4.78, 95% CI = 2.46 to 9.29, P < 0.001) and days of mechanical ventilation (OR = 1.02, 95% CI = 1.01 to 1.03, P < 0.001) were independently associated with B-NP episodes. Bacteremia (OR = 2.01, 95% CI = 1.22 to 3.55, P = 0.008), diagnostic category (medical patients (OR = 3.71, 95% CI = 2.01 to 6.95, P = 0.02) and surgical patients (OR = 2.32, 95% CI = 1.10 to 4.97, P = 0.03)) and higher SAPS II score (OR = 1.02, 95% CI = 1.01 to 1.03, P = 0.008) were independent risk factors for mortality.Conclusions: B-NP episodes are more frequent in patients with medical admission, MRSA and A. baumannii etiology and prolonged mechanical ventilation, and are independently associated with higher mortality rates. © 2011 Magret et al.; licensee BioMed Central Ltd.

Catheter Design and Anticoagulation on Postablation Silent Cerebral Ischemia. Introduction: Silent cerebral lesions (SCL) are a sensitive tool to evaluate thromboembolic risk of catheter ablation. Recent data showed the possibility to reduce thrombus formation when the electrode-tissue interface cooling is optimized by a homogeneous flushing of saline along the entire surface of the distal electrode through a larger number of irrigation holes. The study aim is to compare procedural parameters and safety of pulmonary vein isolation (PVI) performed by using open-irrigated catheters with different irrigation design. Methods and Results: Eighty patients (74% males; age 57 ± 12 years) with paroxysmal AF randomly underwent PVI performed with a new irrigation design catheter (group A, 40 patients) versus a standard irrigated catheter (group B, 40 patients). A cerebral magnetic resonance imaging (MRI) was performed before and after the procedure. Postprocedural brain MRI unveiled SCL in 2 patients in group A and in 3 in group B (5% vs 7.5%, P = 0.500). Intraprocedural ACT was the only independent factor associated with the occurrence of SCL (OR = 0.996; 95% CI 0.994-0.998, P < 0.001). Among procedural parameters, we observed a reduction of irrigation saline volume of 662 mL in group A versus group B (P < 0.001). Conclusion: PVI performed with a new irrigated catheter did not reduce significantly the SCL risk when compared to a standard irrigated catheter. Intraprocedural ACT reduces the SCL risk of 0.4% for each point of ACT increase. For ACT > 320 seconds no SCL occurred. Finally, compared to a standard irrigated catheter, PVI performed with a new irrigation design catheter reduces significantly saline volume infusion. © 2012 Wiley Periodicals, Inc. Source
