Since the development of new human genome sequencing technologies at the beginning of the 2000, commercial companies have developped direct to consumer genomic services, which means without medical prescription. From 2007 to 2013, many companies have offered services assesing associated risk with human public health in the world especially in the United States. This kind of company is forbidden in France. From 2009 to 2013, in United States, under the pressure of national or state health administrations, these companies have been progressively forbidden. However, in certain parts of the world, companies are still offering such services. The latter raise many different questions such as ethical, juridical, medical, scientific, educative, professional one. Many studies and debates have demonstrated their limit and the lack of usefulness and advantage in the field of human health for the time being. The commercialization of this type of services has arrived all too soon et is not yet ripe. In our time of globalization, with the lack of international rules controlling direct access to genetic services in the field of human health, there is an urgent need to regulate. International administrations and politicians must act fast. Inevitably, under the pressure of lobbies and citizens, companies (multinational or not) will develop especially as 1) new sequencing technologies evolve rapidly, 2) are cheaper from year to year, 3) scientific and medical knowledges are progressing quickly, 4) services are spreading faster through the web and other networks.

IMPORTANCE: D-dimer measurement is an important step in the diagnostic strategy of clinically suspected acute pulmonary embolism (PE), but its clinical usefulness is limited in elderly patients. OBJECTIVE: To prospectively validate whether an age-adjusted D-dimer cutoff, defined as age x 10 in patients 50 years or older, is associated with an increased diagnostic yield of D-dimer in elderly patients with suspected PE. DESIGN, SETTINGS, AND PATIENTS: A multicenter, multinational, prospective management outcome study in 19 centers in Belgium, France, the Netherlands, and Switzerland between January 1, 2010, and February 28, 2013. INTERVENTIONS: All consecutive outpatients who presented to the emergency department with clinically suspected PE were assessed by a sequential diagnostic strategy based on the clinical probability assessed using either the simplified, revised Geneva score or the 2-level Wells score for PE; highly sensitive D-dimer measurement; and computed tomography pulmonary angiography (CTPA). Patients with a D-dimer value between the conventional cutoff of 500 μg/L and their age-adjusted cutoff did not undergo CTPA and were left untreated and formally followed-up for a 3-month period. MAIN OUTCOMES AND MEASURES: The primary outcomewas the failure rate of the diagnostic strategy, defined as adjudicated thromboembolic events during the 3-month follow-up period among patients not treated with anticoagulants on the basis of a negative age-adjusted D-dimer cutoff result. RESULTS: Of the 3346 patients with suspected PE included, the prevalence of PE was 19%. Among the 2898 patients with a nonhigh or an unlikely clinical probability, 817 patients (28.2%) had a D-dimer level lower than 500 μg/L (95% CI, 26.6%-29.9%) and 337 patients (11.6%) had a D-dimer between 500 μg/L and their age-adjusted cutoff (95% CI, 10.5%-12.9%). The 3-month failure rate in patients with a D-dimer level higher than 500 μg/L but below the age-adjusted cutoff was 1 of 331 patients (0.3% [95% CI, 0.1%-1.7%]). Among the 766 patients 75 years or older, of whom 673 had a nonhigh clinical probability, using the age-adjusted cutoff instead of the 500 μg/L cutoff increased the proportion of patients in whom PE could be excluded on the basis of D-dimer from 43 of 673 patients (6.4% [95% CI, 4.8%-8.5%) to 200 of 673 patients (29.7% [95% CI, 26.4%-33.3%), without any additional false-negative findings. CONCLUSIONS AND RELEVANCE: Compared with a fixed D-dimer cutoff of 500 μg/L, the combination of pretest clinical probability assessment with age-adjusted D-dimer cutoff was associated with a larger number of patients in whom PE could be considered ruled out with a low likelihood of subsequent clinical venous thromboembolism.

Ventilator-associated tracheobronchitis has been suggested as an intermediate process between tracheobronchial colonisation and ventilator-associated pneumonia in patients receiving mechanical ventilation. We aimed to establish the incidence and effect of ventilator-associated tracheobronchitis in a large, international patient cohort.We did a multicentre, prospective, observational study in 114 intensive care units (ICU) in Spain, France, Portugal, Brazil, Argentina, Ecuador, Bolivia, and Colombia over a preplanned time of 10 months. All patients older than 18 years admitted to an ICU who received invasive mechanical ventilation for more than 48 h were eligible. We prospectively obtained data for incidence of ventilator-associated lower respiratory tract infections, defined as ventilator-associated tracheobronchitis or ventilator-associated pneumonia. We grouped patients according to the presence or absence of such infections, and obtained data for the effect of appropriate antibiotics on progression of tracheobronchitis to pneumonia. Patients were followed up until death or discharge from hospital. To account for centre effects with a binary outcome, we fitted a generalised estimating equation model with a logit link, exchangeable correlation structure, and non-robust standard errors. This trial is registered with, number NCT01791530.Between Sept 1, 2013, and July 31, 2014, we obtained data for 2960 eligible patients, of whom 689 (23%) developed ventilator-associated lower respiratory tract infections. The incidence of ventilator-associated tracheobronchitis and that of ventilator-associated pneumonia at baseline were similar (320 [11%; 102 of 1000 mechanically ventilated days] vs 369 [12%; 88 of 1000 mechanically ventilated days], p=048). Of the 320 patients with tracheobronchitis, 250 received appropriate antibiotic treatment and 70 received inappropriate antibiotics. 39 patients with tracheobronchitis progressed to pneumonia; however, the use of appropriate antibiotic therapy for tracheobronchitis was associated with significantly lower progression to pneumonia than was inappropriate treatment (19 [8%] of 250 vs 20 [29%] of 70, p<00001; crude odds ratio 021 [95% CI 011-041]). Significantly more patients with ventilator-associated pneumonia died (146 [40%] of 369) than those with tracheobronchitis (93 [29%] of 320) or absence of ventilator-associated lower respiratory tract infections (673 [30%] of 2271, p<00001). Median time to discharge from the ICU for survivors was significantly longer in the tracheobronchitis (21 days [IQR 15-34]) and pneumonia (22 [13-36]) groups than in the group with no ventilator-associated lower respiratory tract infections (12 [8-20]; hazard ratio 165 [95% CI 138-197], p<00001).This large database study emphasises that ventilator-associated tracheobronchitis is a major health problem worldwide, associated with high resources consumption in all countries. Our findings also show improved outcomes with use of appropriate antibiotic treatment for both ventilator-associated tracheobronchitis and ventilator-associated pneumonia, underlining the importance of treating both infections, since inappropriate treatment of tracheobronchitis was associated with a higher risk of progression to pneumonia.None.

Perioperative goal directed therapy (PGDT) has been demonstrated to improve postoperative outcomes and reduce the length of hospital stays. The objective of our analysis was to evaluate the cost of complications, derived from French hospital payments, and calculate the potential cost savings and length of hospital stay reductions.The billing of 2,388 patients who underwent scheduled high-risk surgery (i.e. major abdominal, gynaecologic, urological, vascular, and orthopaedic interventions) over three years was retrospectively collected from three French hospitals (one public - teaching, one public, and one private hospital). A relationship between mortality, length of hospital stays, cost/patient, and severity scores, based mainly on postoperative complications but also on preoperative clinical status, were analysed. Statistical analysis was performed using Students t-tests or Wilcoxon tests.Our analyses determined that a severity score of 3 or 4 was associated with complications in 90% of cases and this represented 36% of patients who, compared with those with a score of 1 or 2, were associated with significantly increased costs (8,2053,335 to 22,081 16,090; p<0.001, delta of 13,876) and a prolonged length of hospital stay (median of 10 to 27 days; p<0.001, delta of 17 days). According to estimates for complications avoided by PGDT, there was a projected reduction in average healthcare costs of between 854 and 1,458 per patient and a reduction in total hospital bed days from 2,573 to 4,423 over three years. Based on French National data (47,000 high risk surgeries per year), the potential financial savings ranged from 42M to 65M, not including the costs of PGDT and its implementation.Our analysis demonstrates that patients with complications are significantly more expensive to care for than those without complications. In our model, it was projected that implementing PGDT during high-risk surgery may significantly reduce healthcare costs and the length of hospital stays in France while probably improving patient access to care and reducing waiting times for procedures.

Background: There is no consensual first-line chemotherapy for elderly patients with mantle cell lymphoma (MCL). The GOELAMS (Groupe Ouest-Est des Leucémies Aiguë s et Maladies du Sang) group previously developed the (R)VAD+C regimen (rituximab, vincristine, doxorubicin, dexamethasone and chlorambucil), which appeared as efficient as R-CHOP (rituximab, cyclophosphamide, doxorubicine, vincristine, prednisone) while less toxic. Based on this protocol, we now added bortezomib (RiPAD+C: rituximab, bortezomib, doxorubicin, dexamethasone and chlorambucil) given its efficacy in relapsed/refractory MCL patients. The goal of the current phase II trial was to evaluate the feasibility and efficacy of the RiPAD+C regimen as frontline therapy for elderly patients with MCL. Patients and methods: Patients between 65 and 80 years of age with newly diagnosed MCL received up to six cycles of RiPAD+C. Results: Thirty-nine patients were enrolled. Median age was 72 years (65-80). After four cycles of RiPAD+C, the overall response rate was 79%, including 51% complete responses (CRs). After six cycles, CR rate increased up to 59%. After a 27-month follow-up, median progression-free survival (PFS) is 26 months and median overall survival has not been reached. Four patients (10%) discontinued the treatment because of a severe toxicity and seven patients (18%) experienced grade 3 neurotoxicity. Conclusion: The bortezomib-containing RiPAD+C regimen results in high CR rates and prolonged PFS with predictable and manageable toxic effects in elderly patients with MCL. © The Author 2011.

The aim of this study was to analyse the clinico-pathological characteristics and outcomes of a cohort of French patients who were prospectively screened for Anaplastic Lymphoma Kinase (ALK) rearrangement. One hundred and sixteen consecutive patients screened for ALK rearrangement to be recruited into a crizotinib registration trial were included from eight French centres. ALK rearrangement was detected by fluorescence in situ hybridization. Seventeen patients (14.6%) were positive for ALK. ALK+ patients were younger (p = 0.049) and more likely to be males (p = 0.032), non- or light-smokers (p = 0.048) and without underlying respiratory disease (p = 0.025) compared to ALK- patients. Thyroid-transcription factor-1 expression was present in all ALK+ tumours. ALK+ tumours tended to have lymph node and brain metastases. In multivariate analyses, gender, smoking history and N stage were independently associated with ALK status. Median overall survival (OS) was not reached for ALK+ patients and was significantly longer than for ALK- patients (hazard ratio for death for ALK- patients 2.98; 95% CI [1.29-6.90], p = 0.01). French ALK+ patients present a specific phenotype. ALK rearrangement should be determined to improve OS with an effective targeted therapy. © 2014 Elsevier Ltd. All rights reserved.

Autosomal dominant hypercholesterolemia (ADH) is a human disorder characterized phenotypically by isolated high-cholesterol levels. Mutations in the low density lipoprotein receptor (LDLR), APOB, and proprotein convertase subtilisin/kexin type 9 (PCSK9) genes are well known to be associated with the disease. To characterize the genetic background associated with ADH in France, the three ADH-associated genes were sequenced in a cohort of 120 children and 109 adult patients. Fifty-one percent of the cohort had a possible deleterious variant in LDLR, 3.1% in APOB, and 1.7% in PCSK9. We identified 18 new variants in LDLR and 2 in PCSK9. Three LDLR variants, including two newly identified, were studied by minigene reporter assay confirming the predicted effects on splicing. Additionally, as recently an in-frame deletion in the APOE gene was found to be linked to ADH, the sequencing of this latter gene was performed in patients without a deleterious variant in the three former genes. An APOE variant was identified in three patients with isolated severe hypercholesterolemia giving a frequency of 1.3% in the cohort. Therefore, even though LDLR mutations are the major cause of ADH with a large mutation spectrum, APOE variants were found to be significantly associated with the disease. Furthermore, using structural analysis and modeling, the identified APOE sequence changes were predicted to impact protein function.
