Abstract
We investigated using a custom NGS panel of 149 genes the mutational landscape of 64 consecutive adult patients with tyrosine kinase fusion-negative hypereosinophilia (HE)/hypereosinophilic syndrome (HES) harboring features suggestive of myeloid neoplasm. At least one mutation was reported in 50/64 (78%) patients (compared to 8/44 (18%) patients with idiopathic HE/HES/HEUS used as controls; p < .001). Thirty-five patients (54%) had at least one mutation involving the JAK-STAT pathway, including STAT5B (n = 18, among which the hotspot N642H, n = 13), JAK1 (indels in exon 13, n = 5; V658F/L, n = 2), and JAK2 (V617F, n = 6; indels in exon 13, n = 2). Other previously undescribed somatic mutations were also found in JAK2, JAK1, STAT5B, and STAT5A, including three patients who shared the same STAT5A V707fs mutation and features consistent with primary polycythemia. Nearly all JAK-STAT mutations were preceded by (or associated with) myelodysplasia-related gene mutations, especially in RNA-splicing genes or chromatin modifiers. In multivariate analysis, neurologic involvement (hazard ratio [HR] 4.95 [1.87-13.13]; p = .001), anemia (HR 5.50 [2.24-13.49]; p < .001), and the presence of a high-risk mutation (as per the molecular international prognosis scoring system: HR 6.87 [2.39-19.72]; p < .001) were independently associated with impaired overall survival. While corticosteroids were ineffective in all treated JAK-STAT-mutated patients, ruxolitinib showed positive hematological responses including in STAT5A-mutated patients. These findings emphasize the usefulness of NGS for the workup of tyrosine kinase fusion-negative HE/HES patients and support the use of JAK inhibitors in this setting. Updated classifications could consider patients with JAK-STAT mutations and eosinophilia as a new "gene mutated-entity" that could be differentiated from CEL, NOS, and idiopathic HES.

Abstract
BACKGROUND OF THE STUDY AML classification tools have been developed to stratify the risk at AML diagnosis. There is a need to evaluate these tools in the current therapeutic era. COHORT CHARACTERISTICS In this retrospective study, we compared five classifiers: ELN 2017, ELN 2022, ALFA classifier, Papaemmanuil et al. classifier, and Lindsley et al. classifier, in a real-life cohort of 281 patients newly diagnosed for AML in Nice University Hospital. In our cohort median age was 68 years old, sex ratio was M/F 56%/44%, performance status was lower than 2 in 73.1% of patients, AML subtype was "De novo" in 71.5%, "secondary" in 22.4%, and "therapy-related" in 6.0% of patients. Intensive chemotherapy was used in 53.0% of patients, and non-intensive chemotherapy in 40.6% of patients. Molecular analysis was available in a large majority of patients and the main mutations found were NPM1 (22.7%), DNMT3A (17.4%), TP53 (13.1%), TET2 (12.4%), and FLT3-ITD (12.4%). RESULTS In our findings, the comparison of overall survival between the three prognostic groups in the global cohort was statistically significant in all classifiers: ELN 2017 p < 0.0001, ELN 2022 p < 0.0001, ALFA classifier p < 0.0001, Papaemmanuil classifier p < 0.0001, Lindsley classifier p = 0.001. ELN 2017, ELN 2022, ALFA classifier, Papaemmanuil classifier, and Lindsley classifier were calculated respectively in 99%, 99%, 89%, 90%, and 89% of patients. CONCLUSIONS Using Akaike's information criteria (AIC) to compare all five classifiers, ELN 2022 is the best classifier into younger and older patients and for prognosis.

Abstract
Background: Identification of athletic shoes for patients with contact allergy is difficult. Company reports of allergen content are often incorrect. Objectives: To determine whether chemical analysis of 4 athletic shoes, previously reported to be free of the most common contact allergens, contain quantifiable allergen levels. Methods: Samples from the uppers and insoles of 4 shoes believed to be free of common allergens were assessed by mass spectrometry. A total of 4 rubber accelerators and 2 adhesives were directly quantified and additional 7 rubber accelerators were assessed using semiquantitative measures. Results: Aside from carbamates (assayed as 59 ppm zinc in insoles) in SeaVee's Sixty-Six sneakers, para-tertiarybutylphenol formaldehyde resin (PTBFR) (assayed as 7.6 ppm paratertiary butylphenol or 4-tertiary butylphenol [4TBP] in uppers) in Allbirds Tree Runners and rosin (assayed as 628 ppm sodium abietate in uppers) and carbamates (24 ppm zinc in uppers) in Saucony Jazz sneakers, these shoes had low levels of all allergens assayed in this study. Tom's Carlo sneakers contained rosin (127 ppm sodium abietate in insoles), PTBFR (6.5 ppm 4TBP in uppers), and carbamates (112 ppm sodium abietate in insoles) but had low levels of all other assayed allergens. Conclusions: Although identifying allergen-free shoes is challenging, the results of this analysis will help patch testing physicians recommend athletic shoes to patients with specific allergies.

Abstract
The independent prognostic impact of specific dysplastic features in acute myeloid leukemia (AML) remains controversial and may vary between genomic subtypes. We apply a machine learning framework to dissect the relative contribution of centrally reviewed dysplastic features and oncogenetics in 190 patients with de novo AML treated in ALFA clinical trials. One hundred and thirty-five (71%) patients achieved complete response after the first induction course (CR). Dysgranulopoiesis, dyserythropoiesis and dysmegakaryopoiesis were assessable in 84%, 83% and 63% patients, respectively. Multi-lineage dysplasia was present in 27% of assessable patients. Micromegakaryocytes (q = 0.01), hypolobulated megakaryocytes (q = 0.08) and hyposegmented granulocytes (q = 0.08) were associated with higher ELN-2017 risk. Using a supervised learning algorithm, the relative importance of morphological variables (34%) for the prediction of CR was higher than demographic (5%), clinical (2%), cytogenetic (25%), molecular (29%), and treatment (5%) variables. Though dysplasias had limited predictive impact on survival, a multivariate logistic regression identified the presence of hypolobulated megakaryocytes (p = 0.014) and micromegakaryocytes (p = 0.035) as predicting lower CR rates, independently of monosomy 7 (p = 0.013), TP53 (p = 0.004), and NPM1 mutations (p = 0.025). Assessment of these specific dysmegakarypoiesis traits, for which we identify a transcriptomic signature, may thus guide treatment allocation in AML.

Abstract
To design a simple and reproducible classifier predicting the overall survival (OS) of patients with acute myeloid leukemia (AML) ≥60 years of age treated with 7 + 3, we sequenced 37 genes in 471 patients from the ALFA1200 (Acute Leukemia French Association) study (median age, 68 years). Mutation patterns and OS differed between the 84 patients with poor-risk cytogenetics and the 387 patients with good (n = 13), intermediate (n = 339), or unmeasured (n = 35) cytogenetic risk. TP53 (hazards ratio [HR], 2.49; P = .0003) and KRAS (HR, 3.60; P = .001) mutations independently worsened the OS of patients with poor-risk cytogenetics. In those without poor-risk cytogenetics, NPM1 (HR, 0.57; P = .0004), FLT3 internal tandem duplications with low (HR, 1.85; P = .0005) or high (HR, 3.51; P < 10-4) allelic ratio, DNMT3A (HR, 1.86; P < 10-4), NRAS (HR, 1.54; P = .019), and ASXL1 (HR, 1.89; P = .0003) mutations independently predicted OS. Combining cytogenetic risk and mutations in these 7 genes, 39.1% of patients could be assigned to a "go-go" tier with a 2-year OS of 66.1%, 7.6% to the "no-go" group (2-year OS 2.8%), and 3.3% of to the "slow-go" group (2-year OS of 39.1%; P < 10-5). Across 3 independent validation cohorts, 31.2% to 37.7% and 11.2% to 13.5% of patients were assigned to the go-go and the no-go tiers, respectively, with significant differences in OS between tiers in all 3 trial cohorts (HDF [Hauts-de-France], n = 141, P = .003; and SAL [Study Alliance Leukemia], n = 46; AMLSG [AML Study Group], n = 223, both P < 10-5). The ALFA decision tool is a simple, robust, and discriminant prognostic model for AML patients ≥60 years of age treated with intensive chemotherapy. This model can instruct the design of trials comparing the 7 + 3 standard of care with less intensive regimens.

Abstract
Allergen avoidance is the most effective treatment of contact allergy. Patient improvement ultimately relies on identification of safe alternative products, which can be used by the patient. Safe personal care product options typically can be found using ingredient database programs. Avoidance of allergens in other products (eg, shoes, clothing, and dental care) often is challenging. This article discusses specific safe alternatives for the 80 allergens on the 2017 American Contact Dermatitis Society core allergen series.

Abstract
BACKGROUND Product disclaimers listed on personal care products face limited regulation. These disclaimers may be helpful or may mislead the public. OBJECTIVE Review the evidence supporting the potential harms of three compounds commonly addressed by product disclaimers: parabens, aluminum, and sulfates. METHODS Reported cases of adverse events to these compounds were identified. Trends in allergic contact dermatitis to chemicals used in place of these compounds were also identified. RESULTS There is limited evidence that parabens and aluminum pose a threat to human health; there is even less evidence that topical sulfate containing products pose a danger to consumers. In the setting of paraben avoidence, there has been a steady increase in cases of allergic contact dermatitis to preservatives which are more allergenic, specifically the isothiazolinones. LIMITATIONS Assessment of the toxicology of these compounds is ongoing and may change with new data. CONCLUSION There is limited evidence that parabens, aluminum, and sulfates used in personal care products pose a health risk. There is evidence that avoidance of parabens has resulted in an epidemic of allergic contact dermatitis to isothiazolonine preservatives.

Abstract
Gemtuzumab ozogamicin (GO, Mylotarg®) consists of a humanized CD33-targeted antibody-drug conjugated to a calicheamicin derivative. Growing evidence of GO efficacy in acute myeloid leukemia (AML), demonstrated by improved outcomes in CD33-positive AML patients across phase I to III clinical trials, led to the Food and Drug Administration (FDA) approval on 1 September 2017 in CD33-positive AML patients aged 2 years and older. Discrepancies in GO recipients outcome have raised significant efforts to characterize biomarkers predictive of GO response and have refined the subset of patients that may strongly benefit from GO. Among them, CD33 expression levels, favorable cytogenetics (t(8;21), inv(16)/t(16;16), t(15;17)) and molecular alterations, such as NPM1, FLT3-internal tandem duplications and other signaling mutations, represent well-known candidates. Additionally, in depth analyses including minimal residual disease monitoring, stemness expression (LSC17 score), mutations or single nucleotide polymorphisms in GO pathway genes (CD33, ABCB1) and molecular-derived scores, such as the recently set up CD33_PGx6_Score, represent promising markers to enhance GO response prediction and improve patient management.

Abstract
Carpal tunnel syndrome (CTS) is too common a condition not to daily interact with the practitioner, if only because of its entanglement to other pathologies, causal or chance association. The typical symptomatology, with hand paresthesia and morning pain upon waking, is related to a median nerve injury in the confined space of the carpal tunnel, more often by local inflammation and tenosynovitis of the finger flexors (repetitive activity of the hands). SCC may be secondary to situations (pregnancy) or conditions (edema, hypothyroidism…), which exaggerate the ordinary pathophysiology or cause deposits in the channel (amyloidosis, mucopolysaccharidoses, etc.). Otherwise, SCC is favored by all neuropathies that cause nerve fragility (especially diabetes). It is sometimes the first sign of these various affections of which it can allow early diagnosis. Electroneuromyographic examination (ENMG) is a key examination to confirm the diagnosis (slowing of sensitive and motor conduction of the median nerve through the carpal tunnel, due to local demyelination), to look for a predisposing neuropathy and for signs of seriousness (amplitude reduction of electrophysiological signals) that indicate axonal loss. In SCC forms with only slowed conduction without sign of seriousness, a splint or infiltration treatment may be attempted. If this medical treatment does not bring healing, or if there are signs of seriousness or unbearable pains, a decompression surgery is indicated. Whether it is performed traditionally or endoscopically, it provides fast relief, even immediate.

Abstract
Abstract
Background Outcome of patients with atrial septal defect (ASD) and severe pulmonary arterial hypertension (PAH) relates to right ventricular (RV) function.
Magnetic resonance imaging (MRI) remains the gold standard for evaluating the RV function but it is not used routinely. We investigated the relationship between MRI and multiple echocardiography parameters, including the Right Ventricle End-Systolic Remodeling Index (RVESRI), a new prognostic marker in patients with PAH.
Methods 23 patients with ASD and severe PAH (median age 49y.o.[39-59], Sp0 2 92% [90-95], WHO functional class II or III, mean pulmonary artery pressure 51mmHg [40-59]) were included between 2014 and 2018. All patients underwent MRI and echocardiography assessment. Echocardiographic measurements of RV remodeling and function included TAPSE, RV fractional area change (RVFAC), peak systolic velocity of the tricuspid valve (S’TV), right atrial (RA) area, RV strain, Systolic to diastolic ratio, eccentricity index and RVESRI, defined by septum length divided by lateral wall length (Figure 1). Pericardial effusion was noted.
Results Median RV ejection fraction (EF) evaluated with MRI was 46 % [34-59]. RV dysfunction (RVEF < 45%) was observed in 43% of patients. Median RVFAC and
RVESRI were 29.6%[23-34] and 1.6[1.4-1.7] respectively. By spearman correlation, RVFAC and RVESRI were significantly correlated to RVEF (Rho 0.62, p < 0.007 and
Rho -0.51,p < 0.02 respectively). By linear regression, RVFAC and RVESRI were also correlated to RVEF (R 2 =0.36, p < 0.003 and R 2 =0.34, p < 0.08). Pericardial effusion was associated with RV dysfunction (p< 0.008) and a lower RVFAC (p < 0.01). TAPSE, S’TV and RV strain were not correlated with RVEF.
Conclusion RVFAC, RVESRI and pericardial effusion were markers of RV dysfunction in patients with ASD and severe PAH. RVESRI appears as a simple and reliable parameter for follow-up. Its prognostic value in patients with CHD remains to be demonstrated.

Abstract
Background: B-cell acute lymphoblastic leukemia associated with t(5;14)(q31;q32); IGH-IL3 is an exceptional cause of eosinophilia. The IGH enhancer on 14q32 is juxtaposed to the IL3 gene on 5q31, leading to interleukin-3 overproduction and release of mature eosinophils in the blood. Clinical, biological and outcome data are extremely scarce in the literature. Except for eosinophilia, no relevant common feature has been highlighted in these patients. However, it has been classified as a distinct entity in the World Health Organization classification. Cases Presentation: Eight patients with t(5;14)(q31;q32) treated by French or Austrian protocols were retrospectively enrolled. Array comparative genomic hybridization, multiplex ligation-dependent probe amplification or genomic PCR search for IKZF1 deletion were performed in 7. Sixteen patients found through an exhaustive search in the literature were also analyzed. For those 24 patients, median age at diagnosis is 14.3 years with a male predominance (male to female ratio = 5). Eosinophilia-related symptoms are common (neurologic in 26%, thromboembolic in 26% or pulmonary in 50%). Median white blood cells count is high (72 × 109/L) and linked to eosinophilia (median: 32 × 109/L). Peripheral blasts are present at a low level or absent (median: 0 × 109/L; range: 0–37 × 109/L). Bone marrow morphology is marked by a low blast infiltration (median: 42%). We found an IKZF1 deletion in 5 out of 7 analyzable patients Outcome data are available for 14 patients (median follow-up: 28 months): 8 died and 6 are alive in complete remission. Some of these features are concordant with those seen in patients with other IGH-rearranged B-cell acute lymphoblastic leukemias: young age at onset, male sex, low blast count, high incidence of IKZF1 deletion and intermediate prognosis. Conclusion: Based on shared epidemiological and biological features, B-cell acute lymphoblastic leukemia with t(5;14)(q31;q32) is a peculiar subset of IGH-rearranged B-cell acute lymphoblastic leukemia with an intermediate prognosis and particular clinical features related to eosinophilia.

Abstract
BACKGROUND AND PURPOSE Charcot-Marie-Tooth (CMT) 1C due to mutations in LITAF/SIMPLE is a rare subtype amongst the autosomal dominant demyelinating forms of CMT. Our objective was to report the clinical and electrophysiological characteristics of 18 CMT1C patients and compare them to 20 patients with PMP22 mutations: 10 CMT1A patients and 10 patients with hereditary neuropathy with liability to pressure palsies (HNPP). METHODS Charcot-Marie-Tooth 1C patients were followed-up in referral centres for neuromuscular diseases or were identified by familial survey. All CMT1A and HNPP patients were recruited at the referral centre for neuromuscular diseases of Pitié-Salpêtrière Hospital. RESULTS Two phenotypes were identified amongst 18 CMT1C patients: the classical CMT form ('CMT-like', 11 cases) and a predominantly sensory form ('sensory form', seven cases). The mean CMT neuropathy score was 4.45 in CMT1C patients. Motor nerve conduction velocities in the upper limbs were significantly more reduced in CMT1A than in CMT1C patients. On the other hand, the motor nerve conduction velocity of the median nerve was significantly lower in CMT1C compared to the HNPP group. Distal motor latency was significantly more prolonged in CMT1A patients compared to the CMT1C and HNPP groups, the latter two groups having similar distal motor latency values. Molecular analysis revealed five new LITAF/SIMPLE mutations (Ala111Thr, Gly112Ala, Trp116Arg, Pro135Leu, Arg160Cys). CONCLUSIONS Our study delineates CMT1C as mostly a mild form of neuropathy, and gives clinical and electrophysiological clues differentiating CMT1C from CMT1A and HNPP. Delineating phenotypes in CMT subtypes is important to orient molecular diagnosis and to help to interpret complex molecular findings.

Abstract
In addition to being one of the most acute problems impeding chemical control of fungal diseases, the evolution of fungicide resistance is an emblematic case of local adaptation to spatially heterogeneous and temporally variable selection pressures. Here we dissected the adaptation of Botrytis cinerea (the causal agent of grey mould) populations on grapes to several fungicides. We carried out a 2-year survey (four collection dates) on three treated/untreated pairs of plots from vineyards in Champagne (France) and monitored the frequency of four resistant phenotypes that are unambiguously associated with four distinct genotypes. For two loci under selection by currently used fungicides (MDR1 and MDR2), the frequencies of resistant mutations at vintage were greater in treated plots compared to untreated plots, showing that the effect of selection is detectable even at the plot scale. This effect was not detectable for two other loci under selection by previously used fungicides (BenR1 and ImiR1). We also found that treatment with currently used fungicides reduced B. cinerea effective population size, leading to a significant decrease in genic diversity and allelic richness in treated vs. untreated plots. We further highlight that even under ample drift and migration, fungal populations can present an efficient response to selection. Finally, for the four studied loci, the costs of fungicide resistance were estimated by modelling the decrease in the frequency of resistant mutations in the absence of treatment. We discuss the importance of these estimates for defining strategies for limiting or counteracting the local adaptation of pests to fungicides.

Abstract
Suboptimal culture condition before minor or major genome activation is believed to affect the quality and the transcriptome landscape of the resulting blastocysts. Thus, we hypothesised that exposure of bovine embryos to suboptimal culture condition before minor embryonic genome activation could affect the genome methylation patterns of the resulting blastocysts. Therefore, here we aimed to investigate the genome wide DNA methylation patterns of blastocysts derived from embryos developed up to 2-cell stages in vivo followed by in vitro culture. For this, Simmental heifers were superovulated and artificially inseminated. The 2-cell stage embryos were then flushed using a state-of-the-art nonsurgical endoscopic early-stage embryo flushing technique and in vitro cultured until the blastocyst stage. The DNA methylation patterns of these blastocysts were then determined with reference to blastocysts derived from embryos developed completely under in vivo condition. For this, the genomic DNA isolated from each blastocyst group were fragmented, and unmethylated genomic regions were cleaved using methylation sensitive restriction enzymes. The samples were then amplified using ligation mediated PCR and labelled either with Cy-3 or Cy-5 dyes in a dye-swap design using the ULS Fluorescent genomic DNA labelling kit (Kreatech Biotechnology) and hybridized on an EmbryoGENE DNA Methylation Array as described previously (Saadi 2014 BMC Genomics 15, 451; Salilew-Wondim 2015 PLoS ONE 10, e0140467). Array hybridization was performed for 40 h at 65°C, and 4 hybridizations were preformed to represent 4 biological replicates. The slides were scanned using Agilent’s High-Resolution C Scanner (Agilent Technologies, Santa Clara, CA, USA), and Agilent’s Feature Extraction software (Agilent Technologies) was used to extract data features. Differentially methylated regions with fold change ≥1.5 and P-value < 0.05 were identified using linear modelling for microarray and R software. The results have shown that including imprinted genes (PEG3, IGF1, RASGRF1, IGF2R, GRB10, SNRPN, and PLAGL1) and DNA methyltransferases (DNMT1, DNMT3A, and DNMT3B), a total of 10,388 genomic regions were differentially methylated, of which 6393 genomic regions were hypermethylated in blastocysts derived from 2-cell flush compared with the complete vivo group. In addition, comparative analysis of the current DNA methylation data with our previous transcriptome profile data have shown that including DNMT3A, CTSZ, ElF3E, and PPP2R2B, the expression patterns of 603 genes was inversely correlated with the methylation patterns. Moreover, canonical pathways including gap junction, adherens junction, axon guidance, focal adhesion, and calcium signalling were affected by differentially methylated regions. Therefore, this study indicated that exposure of embryos to suboptimal culture condition before embryonic genome activation would lead to a massive dysregulation of methylation pattern of genes involved in developmentally relevant pathways in the resulting blastocysts.

Abstract
Background Metabolic stress associated with negative energy balance in high producing dairy cattle and obesity in women is a risk factor for decreased fertility. Non-esterified fatty acids (NEFA) are involved in this pathogenesis as they jeopardize oocyte and embryo development. Growing evidence indicates that maternal metabolic disorders can disturb epigenetic programming, such as DNA methylation, in the offspring. Oocyte maturation and early embryo development coincide with methylation changes and both are sensitive to adverse environments. Therefore, we investigated whether elevated NEFA concentrations affect establishment and maintenance of DNA methylation in oocytes and embryos, subsequently altering transcriptomic profiles and developmental competence of resultant blastocysts. Results Bovine oocytes and embryos were exposed to different NEFA concentrations in separate experiments. In the first experiment, oocytes were matured in vitro for 24 h in medium containing: 1) physiological (“BASAL”) concentrations of oleic (OA), palmitic (PA) and stearic (SA) acid or 2) pathophysiological (“HIGH COMBI”) concentrations of OA, PA and SA. In the second experiment, zygotes were cultivated in vitro for 6.5 days under BASAL or HIGH COMBI conditions. Developmental competence was evaluated by assessing cleavage and blastocyst rate. Overall gene expression and DNA methylation of resultant blastocysts were analyzed using microarray. DNA methylation data were re-evaluated by pyrosequencing. HIGH COMBI-exposed oocytes and embryos displayed a lower competence to develop into blastocysts compared to BASAL-exposed counterparts (19.3% compared to 23.2% and 18.2% compared to 25.3%, respectively) (P < 0.05). HIGH COMBI-exposed oocytes and embryos resulted in blastocysts with altered DNA methylation and transcriptomic fingerprints, compared to BASAL-exposed counterparts. Differences in gene expression and methylation were more pronounced after exposure during culture compared to maturation suggesting that zygotes are more susceptible to adverse environments. Main gene networks affected were related to lipid and carbohydrate metabolism, cell death, immune response and metabolic disorders. Conclusions Overall, high variation in methylation between blastocysts made it difficult to draw conclusions concerning methylation of individual genes, although a clear overview of affected pathways was obtained. This may offer clues regarding the high rate of embryonic loss and metabolic diseases during later life observed in offspring from mothers displaying lipolytic disorders.

Abstract
INTRODUCTION The French college of general hospital respiratory physicians (CPHG) has conducted 10 years apart two prospective observational studies to assess changes in the primary lung cancer epidemiology and outcomes, including 1-year mortality. METHODS In 2000 and 2010, all volunteer adult patients followed in the respiratory department of general hospitals participating in the study were consecutively included if their lung cancer was histologically or cytologically diagnosed between 01 January and 31 December (sample date). Their vital status at least 1 year after inclusion and date of death (if applicable) were collected. RESULTS Respectively, 5667 and 7051 patients were included in the study in 2000 and 2010 and vital status of 5441 (96.0%) and 6981 (99%) patients known. One-year mortality rate was 61.8% in 2000 and 56.4% in 2010 (P<0.0001). Mortality rate significantly decreased from 2000 to 2010 in non-small-cell lung cancer (60.7% vs. 55.2%; P<0.0001) but not in small-cell lung cancer (66.9% vs. 64.2%; P=0.22). The year of diagnosis was an independent risk factor of mortality (OR=0.84; 95% CI: 0.77-0.91; P<0.0001). CONCLUSION Although it remains low (43.6% in 2010), life expectancy at 1 year for patients with lung cancer has improved in 10 years. Five-year results are expected to show whether this improvement is maintained or not over time.

Abstract
BACKGROUND The subjective experience of young women with breast cancer has some particular features linked to the impact of the disease and its treatment on their age-related issues (e.g. desire for a child, couple relationship, career management). Despite these specific concerns, no questionnaire currently targets the young breast cancer patient's quality of life, subjective experience or common problems when facing cancer. This study presents the psychometric validation of an inventory that aimed to measure the impact of breast cancer on the quality of life of young women (<45 years of age) with non-metastatic disease. METHODS 546 women aged <45 years when diagnosed with a non-metastatic breast cancer were recruited in 27 French cancer research and treatment centers. They answered a self-reported questionnaire created from verbatim collected by non-directive interviews carried out with 69 patients in a first qualitative study. Exploratory and confirmatory analyses were conducted in order to obtain the final structure of the scale. Internal consistency, test-retest reliability and concurrent validity with quality of life questionnaires currently used (QLQ-C30 and the QLQ-BR23 module) were then assessed. RESULTS The YW-BCI36 contains 36 items and highlights 8 factors: 1) feeling of couple cohesion, 2) negative affectivity and apprehension about the future, 3) management of child(ren) and of everyday life, 4) sharing with close relatives, 5) body image and sexuality, 6) financial difficulties, 7) deterioration of relationships with close relatives, and 8) career management. Psychometric analyses indicated good internal consistency (Cronbach's alpha values ranging from 0.76 to 0.91) and temporal reliability (Bravais-Pearson correlations ranging from 0.66 to 0.85). As expected, there were quite strong correlations between the YW-BCI36 and the QLQ-C30 and QLQ-BR23 scores (r ranging from 0.20 to -0.66), indicating adequate concurrent validity. CONCLUSIONS The YW-BCI36 was confirmed as a valid scale for evaluating the subjective experience of breast cancer in young women. This instrument could help to identify the problems of these women more precisely, in order to respond to them better by an optimal care management. This scale may improve the medical, psychological and social care of breast cancer patients.

Abstract
BACKGROUND To date, no strategy for improving early diagnosis of melanoma has been evaluated on a population basis in France. OBJECTIVE To evaluate the efficacy of a general practitioner (GP) awareness and training campaign in a pilot French geographical region (Champagne-Ardenne), including 1.34 million inhabitants, 1241 GPs, 56 dermatologists and a population-based melanoma registry. METHODS All GPs received repeated awareness postal mailings in 2008 and 398 (32.1%) attended training sessions organized by 27 dermatologists. The pre- (2005-7) and post-campaign (2009-11) periods were compared for the following: primary endpoint - the world-standardized incidence of very thick melanomas (VTM) (Breslow thickness ≥ 3 mm); secondary endpoints--the mean Breslow thickness; the proportions of VTM and of thin (< 1 mm) melanomas among invasive cases; and the ratio of in situ/all melanoma cases. Similar measures were performed in the control area of Doubs/Belfort territory (655,000 ha), where no similar campaign was carried out. RESULTS The incidence of VTM decreased from 1.07 to 0.71 per 100 000 habitants per year (P = 0.01), the mean Breslow thickness from 1.95 to 1.68 mm (P = 0.06) and the proportion of VTM from 19.2% to 12.8% (P = 0.01). The proportion of thin and in situ melanomas increased from 50.9% to 57.4% (P = 0.05) and from 20.1% to 28.2% (P = 0.001), respectively. No significant variation was observed in Doubs/Belfort territory. CONCLUSION These results strongly support the efficacy of such a campaign targeting GPs and provide a rationale for a larger public health campaign in France, including training of GPs by dermatologists and encouraging patients to ask their GP for a systematic skin examination.

Abstract
Most often, in vitro produced embryos display poor quality and altered gene expression patterns compared to their in vivo counterparts. Aberrant DNA methylation occurring during in vitro embryo development is believed to be one of the multifaceted factors which may cause altered gene expression and poor embryo quality. Here, we investigated the genome-wide DNA methylation patterns of in vitro derived embryos using the recently developed Bovine EmbryoGENE Methylation Platform (BEGMP) array (Shojaei Saadi et al. BMC Genomics 2014 15, 451. doi: 10.1186/1471-2164-15-451) to unravel the aberrantly methylated genomic region in in vitro developed embryos. For this, in vitro and in vivo produced blastocysts were produced and used for genome-wide DNA methylation analysis. In vitro blastocysts were produced from oocytes retrieved from ovaries collected from the local abattoir and matured, fertilized, and cultured in vitro using SOF media. The in vivo blastocysts were produced by superovulation and AI of Simmental heifers followed by uterine flushing. Genomic DNA (gDNA) was then isolated from four replicates (each 10 blastocysts) of in vivo and in vitro derived blastocysts using Allprep DNA/RNA micro kit (Qiagen, Valencia, CA, USA) and the gDNA was then fragmented using the MseI enzyme. Following this, MseLig21 and MseLig were ligated to the MseI-digested genomic fragments in the presence of Ligase enzyme. Methyl-sensitive enzymes, HpaII, AciI, and Hinp1I, were used to cleave unmethlayted genomic regions within the MseI-MseI region of the fragmented DNA. The gDNA was subjected to two rounds of ligation-mediated polymerase chain reaction (LM-PCR) amplification. After removal of the adapters, the amplified gDNA samples from in vivo or in vitro groups were labelled either Cy-3 or Cy-5 dyes in dye-swap design using ULS Fluorescent gDNA labelling kit (Kreatech Biotechnology BV, Amsterdam, The Netherlands). Hybridization was performed for 40 h at 65°C. Slides were scanned using Agilent's High-Resolution C Scanner (Agilent Technologies Inc., Santa Clara, CA, USA) and features were extracted with Agilent's Feature Extraction software (Agilent Technologies Inc.). The results have shown that from a total of 414 566 probes harboured by the BEGMP array, 248 453 and 253 147 probes were detected in in vitro and in vivo derived blastocysts, respectively. Data analysis using the linear modelling for microarray (LIMMA) package and R software (The R Project for Statistical Computing, Vienna, Austria) revealed a total of 3434 differentially methylated regions (DMRs; Fold change ≥1.5, P-value <0.05), of which 42 and 58% were hyper- and hypo-methylated, respectively, in in vitro derived blastocysts compared to their in vivo counterparts. The DMRs were found to be localised in the intronic, exonic, promoter, proximal promoter, and distal promoter, and some of the probes did not have nearby genes. In addition, 10.8% of the DMRs were found to be stretched in short, long, or intermediate CpG islands. Thus, this study demonstrated genome-wide dysregulation in the epigenome landscape of in vitro-derived embryos by the time they reach to the blastocysts stage.

Abstract
Species of Pyricularia (magnaporthe-like sexual morphs) are responsible for major diseases on grasses. Pyricularia oryzae (sexual morph Magnaporthe oryzae) is responsible for the major disease of rice called rice blast disease, and foliar diseases of wheat and millet, while Pyricularia grisea (sexual morph Magnaporthe grisea) is responsible for foliar diseases of Digitaria. Magnaporthe salvinii, M. poae and M. rhizophila produce asexual spores that differ from those of Pyricularia sensu stricto that has pyriform, 2-septate conidia produced on conidiophores with sympodial proliferation. Magnaporthe salvinii was recently allocated to Nakataea, while M. poae and M. rhizophila were placed in Magnaporthiopsis. To clarify the taxonomic relationships among species that are magnaporthe- or pyricularia-like in morphology, we analysed phylogenetic relationships among isolates representing a wide range of host plants by using partial DNA sequences of multiple genes such as LSU, ITS, RPB1, actin and calmodulin. Species of Pyricularia s. str. belong to a monophyletic clade that includes all P. oryzae/P. grisea isolates tested, defining the Pyriculariaceae, which is sister to the Ophioceraceae, representing two novel families. These clades are clearly distinct from species belonging to the Gaeumannomyces pro parte/Magnaporthiopsis/Nakataea generic complex that are monophyletic and define the Magnaporthaceae. A few magnaporthe- and pyricularia-like species are unrelated to Magnaporthaceae and Pyriculariaceae. Pyricularia oryzae/P. grisea isolates cluster into two related clades. Host plants such as Eleusine, Oryza, Setaria or Triticum were exclusively infected by isolates from P. oryzae, while some host plant such as Cenchrus, Echinochloa, Lolium, Pennisetum or Zingiber were infected by different Pyricularia species. This demonstrates that host range cannot be used as taxonomic criterion without extensive pathotyping. Our results also show that the typical pyriform, 2-septate conidium morphology of P. grisea/P. oryzae is restricted to Pyricularia and Neopyricularia, while most other genera have obclavate to more ellipsoid 2-septate conidia. Some related genera (Deightoniella, Macgarvieomyces) have evolved 1-septate conidia. Therefore, conidium morphology cannot be used as taxonomic criterion at generic level without phylogenetic data. We also identified 10 novel genera, and seven novel species. A re-evaluation of generic and species concepts within Pyriculariaceae is presented, and novelties are proposed based on morphological and phylogenetic data.
