Aim: Transcatheter aortic valve implantation has become an alternative to surgery in higher risk patients with symptomatic aortic stenosis. The aim of the ADVANCE study was to evaluate outcomes following implantation of a self-expanding transcatheter aortic valve system in a fully monitored, multi-centre 'real-world' patient population in highly experienced centres. Methods and results: Patients with severe aortic stenosis at a higher surgical risk in whom implantation of the CoreValve System was decided by the Heart Team were included. Endpoints were a composite of major adverse cardiovascular and cerebrovascular events (MACCE; all-cause mortality, myocardial infarction, stroke, or reintervention) and mortality at 30 days and 1 year. Endpoint-related events were independently adjudicated based on Valve Academic Research Consortium definitions. A total of 1015 patients [mean logistic EuroSCORE 19.4 ± 12.3% [median (Q1,Q3), 16.0% (10.3, 25.3%)], age 81 ± 6 years] were enrolled. Implantation of the CoreValve System led to a significant improvement in haemodynamics and an increase in the effective aortic valve orifice area. At 30 days, the MACCE rate was 8.0% (95% CI: 6.3-9.7%), all-cause mortality was 4.5% (3.2-5.8%), cardiovascular mortality was 3.4% (2.3-4.6%), and the rate of stroke was 3.0% (2.0-4.1%). The life-threatening or disabling bleeding rate was 4.0% (2.8-6.3%). The 12-month rates of MACCE, all-cause mortality, cardiovascular mortality, and stroke were 21.2% (18.4-24.1%), 17.9% (15.2-20.5%), 11.7% (9.4-14.1%), and 4.5% (2.9-6.1%), respectively. The 12-month rates of all-cause mortality were 11.1, 16.5, and 23.6% among patients with a logistic EuroSCORE ≤10%, EuroSCORE 10-20%, and EuroSCORE >20% (P< 0.05), respectively. Conclusion: The ADVANCE study demonstrates the safety and effectiveness of the CoreValve System with low mortality and stroke rates in higher risk real-world patients with severe aortic stenosis. © 2014 Published on behalf of the European Society of Cardiology.

Parkinson's disease is a neurodegenerative disorder characterized by a cardinal clinical triad that comprises resting tremor, akinesia and plastic hypertonia. The main lesion is a loss of midbbrain dopaminergic neurons but throughout the disease evolution, other neuronal systems will also degenerate. Starting from a typical clinical vignette, this review alms at illustrating how neurosciences helped to shape our knowledge of Parkinson's disease mechanisms at two complementary levels: first regarding the cellular dysfunctions leading to neuronal death and second regarding the neuronal networks involved in the occurrence of motor and non-motor symptoms. The paradigmatic example of subthalamic nucleus deep brain stimulation that dramatically transformed the treatment of patients with advanced Parkinson disease illustrates why the dialog between fundamental and clinical neurosciences is crucial for therapeutic advances.

Objective: To identify the genetic defects present in 3 families with muscular dystrophy, contractures, and calpain 3 deficiency. Methods: We performed targeted exome sequencing on one patient presenting a deficiency in calpain 3 on Western blot but for which mutations in the gene had been excluded. The identification of a homozygous truncating mutation in the M-line part of titin prompted us to sequence this region in 2 additional patients presenting similar clinical and biochemical characteristics. Results: The 3 patients shared similar features: coexistence of limb-girdle weakness and early-onset diffuse joint contractures without cardiomyopathy. The biopsies showed rimmed vacuoles, a dystrophic pattern, and secondary reduction in calpain 3. We identified a novel homozygous mutation in the exon Mex3 of the TTN gene in the first patient. At protein level, this mutation introduces a stop codon at the level of Mex3. Interestingly, we identified truncating mutations in both alleles in the same region of the TTN gene in patients from 2 additional families. Molecular protein analyses confirm loss of the C-ter part of titin. Conclusions: Our study broadens the phenotype of titinopathies with the report of a new clinical entity with prominent contractures and no cardiac abnormality and where the recessive mutations lead to truncation of the M-line titin and secondary calpain 3 deficiency. © 2015 American Academy of Neurology.

Background: Using reduced doses of Cyclosporine A immediately after heart transplantation in clinical trials may suggest benefits for renal function by reducing serum creatinine levels without a significant change in clinical endpoints. However, these trials were not sufficiently powered to prove clinical outcomes.Methods: In a prospective, multicentre, open-label, parallel-group controlled trial, 95 patients aged 18 to 65 years old, undergoing de novo heart transplantation were centrally randomised to receive either a low (130 < trough CsA concentrations <200 μg/L, n = 47) or a standard dose of Cyclosporine A (200 < trough CsA concentrations <300 μg/L, n = 48) for the three first post-transplant months along with mycophenolate mofetil and corticosteroids. Participants had a stable haemodynamic status, a serum creatinine level <250 μmol/L and the donors' cold ischemia time was under six hours; multiorgan transplants were excluded. The change in serum creatinine level over 12 months was used as the main criterion for renal function. Intention-to-treat analysis was performed on the 95 randomised patients and a mixed generalised linear model of covariance was applied.Results: At 12 months, the mean (± SD) creatinine value was 120.7 μmol/L (± 35.8) in the low-dose group and 132.3 μmol/L (± 49.1) in the standard-dose group (P = 0.162). Post hoc analyses suggested that patients with higher creatinine levels at baseline benefited significantly from the lower Cyclosporine A target. The number of patients with at least one rejection episode was not significantly different but one patient in the low-dose group and six in the standard-dose group required dialysis.Conclusions: In patients with de novo cardiac transplantation, early Cyclosporine A dose reduction was not associated with renal benefit at 12 months. However, the strategy may benefit patients with high creatinine levels before transplantation.Trial registration: ClinicalTrials.gov NCT00159159. © 2012 Boissonnat et al.; licensee BioMed Central Ltd.

Summary The care pathway of cancer patients is complex and therefore difficult to define. The oral anticancers (AKPO) have shown their benefits to patients and health professionals, however, the risks induced on the care pathway remain unknown. The objective of the study is to define, quantify the risks from AKPO and their effects on the care pathway (breakdown [Ds], rupture [Rt]). From the proposed care pathway model, FMEA method is used to analyze risks. For the 3 identified processes (1 monotherapy, 2 bitherapies: 2 AKPO or 1 AKPO/1 AKIV), analysis revealed an average of 91 risks, 173 Ds, 147 Rt, increased for 1 AKPO/1 AKIV therapy. The administration and delivery are the most risky steps. The lack of training and information of patients and healthcare professionals generates 80% of Ds and Rt. This model confirms the complexity, variability of the care pathway. The development of actions to improve town-hospital coordination and exchange of information is required to optimize and secure the route, confirming the objectives of "Plan Cancer 3". © 2015 Société Française du Cancer.
