Résumé : International audience
Pituitary adenomas are currently classified by histological, immunocytochemical and numerous ultrastructural characteristics lacking unequivocal prognostic correlations. We investigated the prognostic value of a new clinicopathological classification with grades based on invasion and proliferation. This retrospective multicentric case-control study comprised 410 patients who had surgery for a pituitary tumour with long-term follow-up. Using pituitary magnetic resonance imaging for diagnosis of cavernous or sphenoid sinus invasion, immunocytochemistry, markers of the cell cycle (Ki-67, mitoses) and p53, tumours were classified according to size (micro, macro and giant), type (PRL, GH, FSH/LH, ACTH and TSH) and grade (grade 1a: non-invasive, 1b: non-invasive and proliferative, 2a: invasive, 2b: invasive and proliferative, and 3: metastatic). The association between patient status at 8-year follow-up and age, sex, and classification was evaluated by two multivariate analyses assessing disease- or recurrence/progression-free status. At 8 years after surgery, 195 patients were disease-free (controls) and 215 patients were not (cases). In 125 of the cases the tumours had recurred or progressed. Analyses of disease-free and recurrence/progression-free status revealed the significant prognostic value (p < 0.001; p < 0.05) of age, tumour type, and grade across all tumour types and for each tumour type. Invasive and proliferative tumours (grade 2b) had a poor prognosis with an increased probability of tumour persistence or progression of 25- or 12-fold, respectively, as compared to non-invasive tumours (grade 1a). This new, easy to use clinicopathological classification of pituitary endocrine tumours has demonstrated its prognostic worth by strongly predicting the probability of post-operative complete remission or tumour progression and so could help clinicians choose the best post-operative therapy.

Résumé : International audience
TNF-Related Apoptosis-Inducing Ligand (TRAIL) is a well-known apoptosis inducer, which activates the extrinsic death pathway. TRAIL is pro-apoptotic on colon cancer cells, while not cytotoxic towards normal healthy cells. However, its clinical use is limited by cell resistance to cell death which occurs in approximately 50% of cancer cells. Short Chain Fatty Acids (SCFA) are also known to specifically induce apoptosis of cancer cells. In accordance, we have shown that food grade dairy propionibacteria induce intrinsic apoptosis of colon cancer cells, via the production and release of SCFA (propionate and acetate) acting on mitochondria. Here, we investigated possible synergistic effect between Propionibacterium freudenreichii and TRAIL. Indeed, we hypothesized that acting on both extrinsic and intrinsic death pathways may exert a synergistic pro-apoptotic effect. Whole transcriptomic analysis demonstrated that propionibacterial supernatant or propionibacterial metabolites (propionate and acetate), in combination with TRAIL, increased pro-apoptotic gene expression (TRAIL-R2/DR5) and decreased anti-apoptotic gene expression (FLIP, XIAP) in HT29 human colon cancer cells. The revealed synergistic pro-apoptotic effect, depending on both death receptors (TRAIL-R1/DR4, TRAIL-R2/DR5) and caspases (caspase-8, -9 and -3) activation, was lethal on cancer cells but not on normal human intestinal epithelial cells (HIEC), and was inhibited by Bcl-2 expression. Finally, milk fermented by P. freudenreichii induced HT29 cells apoptosis and enhanced TRAIL cytotoxic activity, as did P. freudenreichii DMEM culture supernatants or its SCFA metabolites. These results open new perspectives for food grade P. freudenreichii-containing products in order to potentiate TRAIL-based cancer therapy in colorectal cancer

Résumé : International audience
The adsorption of some major pharmaceutical products (sulfamethoxazole, caffeine, iopromide and carbamazepine) in water was evaluated using four types of activated carbon, three powdered activated carbon (PAC) and one fluidized, coagulated and flocculated activated carbon (FAC) extracted from a Carboplus®P pilot. These substances were the most frequently quantified (in 50% of samples at least) in surface waters of the Vilaine's basin (Brittany, France) during three sampling campaigns. Jar test experiments were carried out in order to assess the removal efficiency of the four activated carbons. Carbamazepine and caffeine were well removed with PAC with a maximum removal rate of 80% whereas it was more difficult for sulfamethoxazole and iopromide with a maximum of 39%. For each molecule, removal rates are clearly dependent on PAC nature. The overall results with FAC are clearly distinguishable from PAC tests with gains of performance on all target molecules (from 80 to >95%).

Résumé : International audience
The premature loss of ovarian function may have physical and psychological consequences. A better understanding of its mechanism is therefore needed. Because they are affecting the oocyte quality, the decline of the ovarian reserve and high maternal age are implicated in many defects leading to chromosomal defects, modifications of gene expression or alterations of the mitochondrial pattern of the oocyte. However, cellular therapies such as ovarian follicle activation or isolation of ovarian stem cells are promising treatments of ovarian failure
Le diagnostic d’insuffisance ovarienne chez une femme ayant un projet d’enfanter aura des conséquences non seulement physiques mais également psychologiques. L’optimisation des stratégies de prise en charge thérapeutique nécessite une meilleure compréhension des mécanismes de survenue de cette défaillance. Les mécanismes responsables de la constitution et du maintien de la réserve ovarienne commencent à être élucidés. Avec le déclin de la réserve ovarienne, la qualité ovocytaire diminue, accentuant la baisse de la fertilité associée à l’âge maternel. Les ovocytes et les embryons résultant de patientes âgées présentent des taux d’aneuploïdies élevés, liés à des défauts de cohésion chromosomique et d’instabilité du fuseau méiotique, diminution de la capacité de réparation de l’ADN, altération de l’expression des gènes ou à une altération du fonctionnement mitochondrial. Avec la possibilité d’activer in vitro la folliculogenèse et l’isolement de cellules souches ovariennes, plusieurs pistes de thérapie cellulaire commencent à se développer et semblent très prometteuses.

Résumé : International audience
Background Chlordecone is a persistent organochlorine insecticide with well-defined estrogenic properties. It was intensively used in the French West Indies until 1993 to control the banana root borer. Because of the long-term contamination of soils and water, the population is currently exposed to chlordecone through food consumption. Chlordecone has been found in the blood of pregnant women and in cord blood. It has been shown to be an endocrine-disrupting chemical and exposure during pregnancy may affect fetal growth. Objectives The objective of our study was to examine the association between prenatal exposure to chlordecone and fetal growth based on the TIMOUN birth cohort conducted in Guadeloupe, with a focus on the potential modification of this relationship by maternal body mass index (BMI) and gestational weight gain (GWG). Methods Chlordecone was determined in cord plasma at birth in 593 babies. Birth weight was the indicator of fetal growth. Maternal pre-pregnancy BMI and GWG were determined. Adherence to GWG recommendations of the US Institute of Medicine based on maternal pre-pregnancy BMI was assessed. Birth weight was analyzed relative to cord blood chlordecone levels using linear and non-linear regression models. Results Overall chlordecone in cord blood was not associated with birth weight, but we found an interaction between chlordecone exposure with GWG and adherence to GWG recommendations. After stratification by GWG, we found a significant U-shaped association between birth weight and chlordecone exposure, within the upper quartiles of GWG or excessive GWG. Conclusion Chlordecone exposure may affect fetal growth, particularly when excessive GWG is present. © 2016 Elsevier Inc.

Résumé : International audience
The genome of male germ cells is actively transcribed during spermatogenesis to produce phase-specific protein-coding mRNAs and a considerable amount of different noncoding RNAs. Ribonucleoprotein (RNP) granule-mediated RNA regulation provides a powerful means to secure the quality and correct expression of the requisite transcripts. Haploid spermatids are characterized by a unique, unusually large cytoplasmic granule, the chromatoid body (CB), which emerges during the switch between the meiotic and post-meiotic phases of spermatogenesis. To better understand the role of the CB in male germ cell differentiation, we isolated CBs from mouse testes and revealed its full RNA and protein composition. We showed that the CB is mainly composed of RNA-binding proteins and other proteins involved RNA regulation. The CB was loaded with RNA, including pachytene piRNAs, a diverse set of mRNAs, and a number of uncharacterized long noncoding transcripts. The CB was demonstrated to accumulate nascent RNA during all the steps of round spermatid differentiation. Our results revealed the CB as a large germ cell-specific RNP platform that is involved in the control of the highly complex transcriptome of haploid male germ cells.

Résumé : International audience
Leishmaniasis is endemic in southern Europe, and in other European countries cases are diagnosed in travellers who have visited affected areas both within the continent and beyond. Prompt and accurate diagnosis poses a challenge in clinical practice in Europe. Different methods exist for identification of the infecting Leishmania species. Sixteen clinical laboratories in 10 European countries, plus Israel and Turkey, conducted a study to assess their genotyping performance. DNA from 21 promastigote cultures of 13 species was analysed blindly by the routinely used typing method. Five different molecular targets were used, which were analysed with PCR-based methods. Different levels of identification were achieved, and either the Leishmania subgenus, species complex, or actual species were reported. The overall error rate of strains placed in the wrong complex or species was 8.5%. Various reasons for incorrect typing were identified. The study shows there is considerable room for improvement and standardisation of Leishmania typing. The use of well validated standard operating procedures is recommended, covering testing, interpretation, and reporting guidelines. Application of the internal transcribed spacer 1 of the rDNA array should be restricted to Old World samples, while the heat-shock protein 70 gene and the mini-exon can be applied globally.

Résumé : International audience
Objective Oxidative stress, excess production of reactive oxygen species (ROS) and intense colonization of the respiratory tract by microorganisms are described in CF patients, leading to an influx in macrophages. This results in activation of NADPH oxidase that yields ROS, initiating the oxidative burst responsible for pathogen destruction. We showed that phagocytosis was altered in CF macrophages, yet oxidative status in this cell was not defined. The objective of this study is to draw a link between oxidative stress and plasma membrane integrity in CF macrophages, since lipid peroxidation is known to alter cell membrane. Methods Peripheral blood monocytes-derived macrophages were obtained from CF patients and healthy subjects. Plasma membrane fluidity was assessed with di4-ANEPPDHQ and oxidative status was measured with ROS indicating probes. Results In CF macrophages, membrane fluidity was increased whereas lipid peroxidation was diminished. Surprisingly, general oxidative status remained similar to the one observed in non-CF macrophages. Also, CF macrophages did not abolish chemically induced-oxidative stress. In non-CF macrophages, treatment with cholesterol slightly increased membrane fluidity whereas LPS treatment had no effect. Conclusion CF macrophages displayed an increased membrane fluidity associated with a decreased lipid peroxidation. This raises the hypothesis that membrane alteration in CF macrophages may be due to other mechanism than oxidative stress. Nevertheless, since the killing capacity of CF macrophage is defective, a deregulation of O•−2 production is very likely, suggesting alteration of NADPH oxidase or mitochondrial dysfunction

Résumé : National audience
Pneumocystis jiroveci (anciennement P. carinii) est un champignon opportuniste responsable de pneumopathies chez les patients immunodéprimés. Les pneumocystoses des patients non infectés par le VIH se distinguent des pneumocystoses du sida par des difficultés diagnostiques accrues, et un pronostic plus sombre. Il est donc indispensable de cibler les immunodépressions les plus à risque, qui bénéficieront d’un traitement par triméthoprime-sulfaméthoxazole à faible dose au long cours, très efficace en prophylaxie des pneumocystoses : ainsi, les vascularites des moyens et petits vaisseaux, les hémopathies lymphoïdes B (leucémie lymphoïde chronique ou aiguë, lymphome malin non hodgkinien) et les cancers solides sous corticothérapie prolongée doivent faire envisager cette prophylaxie. À l’inverse, la généralisation de la prophylaxie à l’ensemble des patients porteurs de pathologies inflammatoires sous corticothérapie n’est pas justifiée. La prise en charge des pneumocystoses des patients non infectés par le VIH suit les principes établis pour les pneumocystoses du sida. Le diagnostic de certitude repose sur la mise en évidence de kystes de P. jiroveci sur des prélèvements respiratoires, tandis que la PCR ne permet pas formellement, en 2015, de différencier colonisation et infection. Le traitement repose sur le triméthoprime-sulfaméthoxazole à fortes doses. Par contre, l’intérêt de la corticothérapie adjuvante pour les patients hypoxémiques, parfaitement documenté au cours du sida, est discuté pour les autres immunodépressions, d’autant que les patients sont en général déjà sous corticoïdes au moment du diagnostic de pneumocystose. Celle-ci est cependant préconisée par plusieurs experts et sociétés savantes, compte tenu du bénéfice démontré sur la morbi-mortalité au cours du sida. Abstract Pneumocystis jiroveci (formerly P. carinii) is an opportunistic fungus responsible for pneumonia in immunocompromised patients. Pneumocystosis in non-HIV-infected patients differs from AIDS-associated pneumocystosis in mostly two aspects: diagnosis is more difficult, and prognosis is worse. Hence, efforts should be made to target immunocompromised patients at higher risk of pneumocystosis, so that they are prescribed long-term, low-dose, trimethoprime-sulfamethoxazole, highly effective for pneumocystosis prophylaxis. Patients at highest risk include those with medium and small vessels vasculitis, lymphoproliferative B disorders (chronic or acute lymphocytic leukaemia, non-Hodgkin lymphoma), and solid cancer on long-term corticosteroids. Conversely, widespread use of prophylaxis in all patients carrier of inflammatory diseases on long-term corticosteroids is not warranted. The management of pneumocystosis in non-AIDS immunocompromised patients follows the rules established for AIDS patients. The diagnosis relies on the detection of P. jiroveci cyst on respiratory samples, while PCR does not reliably discriminate infection from colonization, in 2015. High-doses trimethoprim-sulfamethoxazole is, by far, the treatment of choice. The benefit of adjuvant corticosteroid therapy for hypoxic patients, well documented in AIDS patients, has a much lower level of evidence in non-HIV-infected patients, most of them being already on corticosteroid by the time of pneumocystosis diagnosis anyway. However, based on its striking impact on morbi-mortality in AIDS patients, adjuvant corticosteroid is recommended in hypoxic, non-HIV-infected patients with pneumocystosis by many experts and scientific societies

Résumé : International audience
Millimeter waves (MMW) will be increasingly used for future wireless telecommunications. Previous studies on skin keratinocytes showed that MMW could impact the mRNA expression of Transient Receptor Potential cation channel subfamily Vanilloid, member 2 (TRPV2). Here, we investigated the effect of MMW exposure on this marker, as well as on other membrane receptors such as Transient Receptor Potential cation channel subfamily Vanilloid, member 1 (TRPV1) and purinergic receptor P2X, ligand-gated ion channel, 3 (P2 × 3). We exposed the Neuroscreen-1 cell line (a PC12 subclone), in order to evaluate if acute MMW exposures could impact expression of these membrane receptors at the protein level. Proteotoxic stress-related chaperone protein Heat Shock Protein 70 (HSP70) expression level was also assessed. We used an original high-content screening approach, based on fluorescence microscopy, to allow cell-by-cell analysis and to detect any cell sub-population responding to exposure. Immunocytochemistry was done after 24 h MMW exposure of cells at 60.4 GHz, with an incident power density of 10 mW/cm2. Our results showed no impact of MMW exposure on protein expressions of HSP70, TRPV1, TRPV2, and P2 × 3. Moreover, no specific cell sub-populations were found to express one of the studied markers at a different level, compared to the rest of the cell populations. However, a slight insignificant increase in HSP70 expression and an increase in protein expression variability within cell population were observed in exposed cells, but controls showed that this was related to thermal effect.

Résumé : International audience
The use of recombinant antigens has been shown to improve both the sensitivity and the standardization of the serological diagnosis of Farmer's lung disease (FLD). The aim of this study was to complete the panel of recombinant antigens available for FLD serodiagnosis with antigens of Lichtheimia corymbifera, known to be involved in FLD. L. corymbifera proteins were thus separated by 2D electrophoresis and subjected to western blotting with sera from 7 patients with FLD and 9 healthy exposed controls (HEC). FLD-associated immunoreactive proteins were identified by mass spectrometry based on a protein database specifically created for this study and subsequently produced as recombinant antigens. The ability of recombinant antigens to discriminate patients with FLD from controls was assessed by ELISA performed with sera from FLD patients (n = 41) and controls (n = 43) recruited from five university hospital pneumology departments of France and Switzerland. Forty-one FLD-associated immunoreactive proteins from L. corymbifera were identified. Six of them were produced as recombinant antigens. With a sensitivity and specificity of 81.4 and 77.3% respectively, dihydrolipoyl dehydrogenase was the most effective antigen for discriminating FLD patients from HEC. ELISA performed with the putative proteasome subunit alpha type as an antigen was especially specific (88.6%) and could thus be used for FLD confirmation. The production of recombinant antigens from L. corymbifera represents an additional step towards the development of a standardized ELISA kit for FLD diagnosis. © 2016 Rognon et al.

Résumé : International audience
Telomerase reverse transcriptase (TERT) or telomerase RNA (TERC) gene mutation is a major monogenic cause of pulmonary fibrosis. Sequencing of TERT/TERC genes is proposed to patients with familial pulmonary fibrosis. Little is known about the possible predictors of this mutation and its impact on prognosis. We retrospectively analysed all the genetic diagnoses made between 2007-2014 in patients with pulmonary fibrosis. We evaluated the prevalence of TERT/TERC disease-Associated variant (DAV), factors associated with a DAV, and the impact of the DAV on survival. 237 patients with pulmonary fibrosis (153 with familial pulmonary fibrosis, 84 with telomere syndrome features without familial pulmonary fibrosis) were tested for TERT/TERC DAV. DAV was diagnosed in 40 patients (16.8%), including five with non-idiopathic interstitial pneumonia. Prevalence of TERT/TERC DAV did not significantly differ between patients with familial pulmonary fibrosis or with only telomere syndrome features (18.2% versus 16.4%). Young age, red blood cell macrocytosis, and low platelet count were associated with the presence of DAV; the probability of DAV was increased for patients 40-60 years. Transplant-free survival was lower with than without TERT/TERC DAV (4.2 versus 7.2 years; p=0.046). TERT/TERC DAV were associated with specific clinical and biological features and reduced transplantfree survival. ©ERS 2016.

Résumé : International audience
The aim of this study was to determine factors associated with complete satisfaction with the care provided (satisfaction with physicians and satisfaction with services and organization) among HIV-infected patients followed up in the French ANRS CO8 APROCO-COPILOTE cohort. Analyses focused on cross-sectional data collected during the ninth year of cohort follow-up. Satisfaction with care, sociodemographic characteristics, and behavioral data were collected using self-administered questionnaires, while clinical data were derived from medical records. Complete satisfaction with care was defined as being 100% satisfied. Two logistic regression models were used to identify predictors of (1) complete satisfaction with physicians (n=404) and (2) complete satisfaction with services and organization (n=396). Sixteen percent of patients were completely satisfied with physicians, while 15.9% were completely satisfied with services and organization. Being older and reporting fewer discomforting antiretroviral therapy (ART) side effects were factors independently associated with complete satisfaction with both physicians and services and organization. Strong support from friends and absence of hepatitis C (HCV) co-infection were independently associated with complete satisfaction with physicians, while strong support from one's family and comfortable housing conditions were independently associated with complete satisfaction with services and organization. Even after nine years of follow-up, social vulnerabilities still strongly influence HIV-infected patients' interactions with the health care system. Day-to-day experience with the disease, including perceived treatment side effects, appears to play a key role in the quality of these interactions. More attention should be given to patient satisfaction, especially for socially vulnerable patients, in order to avoid potentially detrimental consequences such as poor adherence to ART.
