Abstract
The black truffle Tuber melanosporum was disseminated all over the world, propelled by the development of a wide variety of empirical practices. A widespread practice, called ‘truffle trap’, consists of placing pieces of truffles into excavations dug under host trees, and of collecting truffle in these traps in the next years. This research aims at (1) evaluating the effect of this practice on fruitbody production based on the analysis of 9924 truffle traps installed in 11 orchards across T. melanosporum native area in France and (2) exploring the mechanisms involved in fruitbody emergence using traps where the genotypes of introduced truffles were compared with those of fruitbodies collected in the same traps. We confirmed that truffle traps provide a major and highly variable part of truffle ground production, representing up to 89% of the collected fruitbodies. We evidenced a genetic link between introduced spores and collected fruitbodies, and then demonstrated that truffle growers provide paternal partners for mating with local maternal mycelia. We also highlighted that soil disturbance stimulate the vegetative development of established maternal mycelia. This research supports that a widely used traditional practice enhances fruitbody production by shaping favorable conditions and providing sexual partners required for fruiting.

Abstract
BACKGROUND Invasive lobular breast cancer (ILC) is the second most common type of breast cancer after invasive breast cancer of no special type (NST), representing up to 15% of all breast cancers. DESIGN Latest data on ILC are presented, focusing on diagnosis, molecular make-up according to the European Society for Medical Oncology Scale for Clinical Actionability of molecular Targets (ESCAT) guidelines, treatment in the early and metastatic setting and ILC-focused clinical trials. RESULTS At the imaging level, magnetic resonance imaging-based and novel positron emission tomography/computed tomography-based techniques can overcome the limitations of currently used imaging techniques for diagnosing ILC. At the pathology level, E-cadherin immunohistochemistry could help improving inter-pathologist agreement. The majority of patients with ILC do not seem to benefit as much from (neo-)adjuvant chemotherapy as patients with NST, although chemotherapy might be required in a subset of high-risk patients. No differences in treatment efficacy are seen for anti-human epidermal growth factor receptor 2 (HER2) therapies in the adjuvant setting and cyclin-dependent kinases 4 and 6 inhibitors in the metastatic setting. The clinical utility of the commercially available prognostic gene expression-based tests is unclear for patients with ILC. Several ESCAT alterations differ in frequency between ILC and NST. Germline BRCA1 and PALB2 alterations are less frequent in patients with ILC, while germline CDH1 (gene coding for E-cadherin) alterations are more frequent in patients with ILC. Somatic HER2 mutations are more frequent in ILC, especially in metastases (15% ILC versus 5% NST). A high tumour mutational burden, relevant for immune checkpoint inhibition, is more frequent in ILC metastases (16%) than in NST metastases (5%). Tumours with somatic inactivating CDH1 mutations may be vulnerable for treatment with ROS1 inhibitors, a concept currently investigated in early and metastatic ILC. CONCLUSION ILC is a unique malignancy based on its pathological and biological features leading to differences in diagnosis as well as in treatment response, resistance and targets as compared to NST.

Abstract
Abstract
PD-1/PD-L1 blockade has improved survival across many types of cancer, but only in a minority of patients. Co-targeting PD-1/PD-L1 and the CD47/SIRPα myeloid checkpoint with monoclonal antibody (mAb) combinations showed increased antitumor responses in preclinical studies. However, CD47 mAbs are hindered by ubiquitous CD47 expression leading to rapid target-mediated clearance and safety concerns, including anemia and thrombocytopenia. Consequently, dual-targeting CD47xPD-L1 bispecific antibodies (bsAbs) enabling selective inhibition of CD47 on PD-L1-positive tumors offer an alternative approach. A fully human bsAb pairing a high affinity PD-L1 arm to a low affinity CD47 arm was generated using the κλ-body platform. The latter is also used in our CD47xCD19 bispecific antibody NI-1701/TG-1801, currently in phase I clinical trials (NCT03804996, NCT04806035). The resulting CD47xPD-L1 bsAb of human IgG1 isotype (NI-2601) was evaluated in various binding and receptor-blocking assays, and then tested for its capacity to enhance T-cell activation in vitro and induce Fc-mediated killing of tumor cells through phagocytosis (ADCP) and antibody-dependent cell cytotoxicity (ADCC). A surrogate bsAb was also evaluated in vivo in a syngeneic mouse model. NI-2601 demonstrated effective blockade of PD-1/PD-L1 interaction, and T-cell activation in vitro, similar to the anti-PD-L1 clinical benchmarks atezolizumab and avelumab. Consistent with its low-affinity CD47 arm, the bsAb did not bind to red blood cells (RBC) and CD47 blockade was driven by PD-L1 co-engagement. Using a panel of tumor cell lines, expressing various PD-L1 levels, NI-2601 showed superior activity in ADCP and ADCC as compared to the anti-PD-L1 IgG1 mAb, avelumab. The anti-tumor activity of this approach using surrogate CD47xPD-L1 bsAb was confirmed in a syngeneic MC38 colon carcinoma model. Thus, NI-2601 is able to harness Fc-effector function to eliminate PD-L1-positive tumor cells while sparing PD-L1-negative cells, such as RBC or platelets. Pharmacokinetic and tolerability studies in non-human primate are planned for 2022.

Abstract
BackgroundPD-1/PD-L1 blockade can significantly improve survival across many types of cancer, but only in a minority of patients. To broaden its therapeutic efficacy, several combination partners are now being evaluated together with PD-1/PD-L1 blockade. Agents blocking CD47/SIRPα innate immune checkpoint are one such example, and co-targeting PD-1/PD-L1 and CD47 with monoclonal antibody (mAb) combinations showed increased antitumor responses in preclinical studies. However, CD47 mAbs are hindered by ubiquitous CD47 expression leading to rapid target-mediated clearance and safety concerns. Consequently, dual-targeting CD47xPD-L1 bispecific antibodies (bsAbs) enabling preferential inhibition of CD47 on PD-L1-positive cells are being tested as an alternative approach. We compare here two distinct bsAbs, based on a common PD-L1 antibody arm, with differing FcgR-enabling effector functions and CD47-binding arm affinities.MethodsAn array of fully human bsAbs associating a high affinity PD-L1 arm to CD47 arms with varying affinities were generated using the κλ-body platform.1 CD47xPD-L1 bsAbs of human IgG1 isotype (CD47 low affinities) or IgG4 isotype (CD47 high affinities) were screened in various binding assays (including to red blood cells (RBC)) and in receptor-blocking assays, and then tested for their Fc-mediated killing and T-cell activation activity (SEA-stimulated PBMC assay). Selected molecules were evaluated in vivo.ResultsBoth bsAb approaches demonstrated strong blockade of PD-1/PD-L1 interaction and significantly enhanced T-cell activation in vitro. CD47lowxPD-L1 IgG1 bsAbs did not bind to RBC and showed PD-L1-guided inhibition of CD47. ADCP and ADCC experiments with a panel of tumor cell lines expressing various target levels showed superior killing activity with CD47lowxPD-L1 IgG1 bsAbs as compared to the anti-PD-L1 IgG1 mAb, avelumab. On the other hand, CD47highxPD-L1 IgG4 bsAbs showed residual RBC binding and PD-L1-independent blocking of CD47/SIRPα. These CD47high IgG4 bsAbs were able to enhance the anti-tumor activity of anti-tumor-associated antigen (TAA) mAbs in vitro (phagocytosis), and in vivo (Raji lymphoma xenograft model). In addition, anti-tumor activity of mouse CD47xPD-L1 bsAbs in a syngeneic MC38 colon carcinoma model was demonstrated.ConclusionsWith the objective of finding the optimal CD47xPD-L1 bsAb design, two approaches targeting CD47 and PD-L1 inhibition were tested. Both the CD47lowxPD-L1 IgG1 bsAbs and CD47highxPD-L1 IgG4 bsAbs were able to mediate enhanced antitumor responses, the former as a standalone treatment, the latter in conjunction with an anti-TAA mAb. To further characterize the CD47lowxPD-L1 and CD47highxPD-L1 bsAbs, lead candidates will be tested in PK and tolerability studies in non-human primates.ReferencesFischer N, Elson G, Magistrelli G, Dheilly E, Fouque N, Laurendon A, et al.

Abstract
Mesothelin (MSLN) is a cell surface glycoprotein overexpressed in several solid malignancies, including gastric, lung, mesothelioma, pancreatic and ovarian cancers. While several MSLN-targeting therapeutic approaches are in development, only limited efficacy has been achieved in patients. A potential shortcoming of several described antibody-based approaches is that they target the membrane distal region of MSLN and, additionally, are known to be handicapped by the high levels of circulating soluble MSLN in patients. We show here, using monoclonal antibodies (mAbs) targeting different MSLN-spanning epitopes, that the membrane-proximal region resulted in more efficient killing of MSLN-positive tumor cells in antibody-dependent cell-mediated cytotoxicity (ADCC) assays. Surprisingly, no augmented killing was observed in antibody-dependent cellular phagocytosis (ADCP) by mAbs targeting this membrane-proximal region. To further increase the ADCP potential, we, therefore, generated bispecific antibodies (bsAbs) coupling a high-affinity MSLN binding arm to a blocking CD47 arm. Here, targeting the membrane-proximal domain of MSLN demonstrated enhanced ADCP activity compared to membrane-distal domains when the bsAbs were used in in vitro phagocytosis killing assays. Importantly, the superior anti-tumor activity was also translated in xenograft tumor models. Furthermore, we show that the bsAb approach targeting the membrane-proximal epitope of MSLN optimized ADCC activity by augmenting FcγR-IIIA activation and enhanced ADCP via a more efficient blockade of the CD47/SIRPα axis.

Abstract
Abstract
Up-regulation of CD47 is an immune evasion mechanism used by different cancers to evade immune surveillance. Through its interaction with signal-regulatory protein alpha (SIRPα) on myeloid cells, CD47 delivers a universal “don’t eat me” signal to phagocytes, which prevents immune cells from efficiently eliminating tumor cells. Blockade of the SIRPα–CD47 innate immune checkpoint has therefore emerged as a new way to treat cancer. Several CD47-targeting molecules are in development with encouraging results obtained with monoclonal antibodies (mAb). However, the pharmacologic properties and the safety profile of molecules indiscriminately blocking CD47 can be improved by selectively inhibiting CD47 only on tumor cells. For this purpose, we generated bispecific antibodies (bsAbs) capable of targeting blockade of CD47 specifically to malignanT-cells through the co-engagement of a tumor-associated antigen (TAA). The bsAb NI-1801 specifically targets mesothelin (MSLN)-positive tumors. NI-1801 was shown to bind to MSLN-positive tumor cells, but not to MSLN-negative cells expressing physiologic levels of CD47 (e.g., leukocytes, erythrocytes, platelets). NI-1801 blocks the CD47-SIRPα interaction in a MSLN-dependent manner and thus minimizes the side effects related to a nonspecific blockade of CD47 on healthy cells. Studying antibody-dependent cellular phagocytosis (ADCP) and antibody-dependent cellular cytotoxicity (ADCC) of various MSLN-positive human tumor cell lines revealed that NI-1801 markedly enhanced killing as compared to amatuximab (an anti-MSLN mAb in clinical trials) and to the corresponding anti-MSLN mAb, exemplifying the role of blocking the “don’t eat me” signal to target cancer. NI-1801 also showed efficacy in various xenograft tumor models and analysis of the tumor microenvironment (TME) revealed a significant increase in leukocyte subpopulations (macrophages/monocytes and NK cells) of NI-1801 treated mice, suggesting that NI-1801 mediates the recruitment of monocytes from blood. Additionally, NI-1801 treatment affected the ratio between MHC-II-low and MHC-II-high macrophages in the TME. Finally, nonhuman primate studies with NI-1801 demonstrated a linear elimination profile, minimal target-mediated drug disposition and no hematologic toxicity. Taken together, these results illustrate that this strategy possesses potent anticancer activities both in vitro and in vivo in conjunction with favorable pharmacologic and toxicologic profiles.

Abstract
CD19 is a B cell-specific receptor that regulates the threshold of B cell receptor (BCR)-mediated cell proliferation. A CD47xCD19 bispecific antibody (biAb) was generated to target and deplete B cells via multiple antibody-mediated mechanisms. Interestingly, the biAb, constructed of a CD19 binding arm and a CD47 binding arm, inhibited BCR-mediated B-cell proliferation with an effect even more potent than a CD19 monoclonal antibody (mAb). The inhibitory effect of the biAb was not attributable to CD47 binding because a monovalent or bivalent anti-CD47 mAb had no effect on B cell proliferation. Fluorescence resonance energy transfer analysis demonstrated that co-engaging CD19 and CD47 prevented CD19 clustering and its migration to BCR clusters, while only engaging CD19 (with a mAb) showed no impact on either CD19 clustering or migration. The lack of association between CD19 and the BCR resulted in decreased phosphorylation of CD19 upon BCR activation. Furthermore, the biAb differentially modulated BCR-induced gene expression compared to a CD19 mAb. Taken together, this unexpected role of CD47xCD19 co-ligation in inhibiting B cell proliferation illuminates a novel approach in which two B cell surface molecules can be tethered, to one another in order, which may provide a therapeutic benefit in settings of autoimmunity and B cell malignancies.

Abstract
CD47, an ubiquitously expressed innate immune checkpoint receptor that serves as a universal "don't eat me" signal of phagocytosis, is often upregulated by hematologic and solid cancers to evade immune surveillance. Development of CD47-targeted modalities is hindered by the ubiquitous expression of the target, often leading to rapid drug elimination and hemotoxicity including anemia. To overcome such liabilities, we have developed a fully human bispecific antibody, NI-1701, designed to coengage CD47 and CD19 selectively on B cells. NI-1701 demonstrates favorable elimination kinetics with no deleterious effects seen on hematologic parameters following single or multiple administrations to nonhuman primates. Potent in vitro and in vivo activity is induced by NI-1701 to kill cancer cells across a plethora of B-cell malignancies and control tumor growth in xenograft mouse models. The mechanism affording maximal tumor growth inhibition by NI-1701 is dependent on the coengagement of CD47/CD19 on B cells inducing potent antibody-dependent cellular phagocytosis of the targeted cells. NI-1701-induced control of tumor growth in immunodeficient NOD/SCID mice was more effective than that achieved with the anti-CD20 targeted antibody, rituximab. Interestingly, a synergistic effect was seen when tumor-implanted mice were coadministered NI-1701 and rituximab leading to significantly improved tumor growth inhibition and regression in some animals. We describe herein, a novel bispecific antibody approach aimed at sensitizing B cells to become more readily phagocytosed and eliminated thus offering an alternative or adjunct therapeutic option to patients with B-cell malignancies refractory/resistant to anti-CD20-targeted therapy.

Abstract
In July 2013, the European Regulation (EC) No 1223/2009 came into effect in order to secure cosmetic products. The content-containing interaction between the packaging and the product must be considered for the safety assessment. Indeed, some compounds are able to migrate from the packaging to the product and may be harmful to the consumer health. This is why a first test was established by EXPERTOX laboratory in 2012 to deal with this new regulation. A new analytical method was developed and validated for the quantification of 23 substances able to migrate from the packaging to the product. It was applied on a plastic packaging with the five simulants of migration. To evaluate the content-containing interaction, a gas chromatography-mass spectrometry method was developed and validated. Liquid-liquid extraction was used to extract contaminants (thirteen phthalates and ten substances of very high concern) from migration simulants. Calibration curves showed good linearity regression from 2 to 50 μg mL-1 for nineteen molecules and from 5 to 45 μg mL-1 for the others. The limits of quantification were respectively 2 and 5 μg mL-1 . The accuracy, precision, repeatability of the analytical method and extraction yields were acceptable. No molecule was found in simulants of migration, so the potential contaminants present in the packaging did not migrate. A gas chromatography-mass spectrometry method and liquid-liquid extraction were validated for 23 molecules and can be used for the evaluation of the content-containing interaction of cosmetic products. Both quantification and extraction procedures are more robust and faster than previous method.

Abstract
OBJECTIVE The aim of the study was to report the very long-term functional outcomes of artificial urinary sphincter (AUS) in male neurological patients. MATERIAL AND METHODS Male neurological patients diagnosed with stress urinary incontinence due to sphincter deficiency and undergoing AUS (AMS 800®) implantation between 1985 and 1992 were enrolled. Continence, defined by no pad/condom usage, explantation and revision rates were reported. RESULTS Fourteen patients with a median age of 27.3 years (IQR: 27.3-40.8) were included: four had a spinal cord injury and ten a spina bifida. Prior continence surgery was reported by 6 patients (42.9 %). Artificial urinary sphincter was implanted in a peribulbar (n=4) or periprostatic position (n=10). Median follow-up was 18.3 years (IQR: 10.1-20.3). At last follow-up, all patients were alive. Three native devices were still in place, eight were revised (four of them were secondarily explanted) and three were explanted due to erosion or infection. The 5-, 10-, 15-, 20-year explantation-free survival rates were respectively 85.7, 62.3, 52.0, 39.0 %. The 5-, 10-, 15-, 20-year revision-free survival rates were respectively 78.6, 42.9, 28.6, 7.1 %. At last follow-up, 50 % patients were continent. CONCLUSION In the very long run, AUS provided a 50 % continence rate in male neurological patients but the revision rates were important. LEVEL OF EVIDENCE 4.

Abstract
Two rabbit lines have been created to result in better feed efficiency: the ConsoResidual line was selected for a lower residual feed intake under ad libitum feeding, and the ADGrestrict line was selected for higher ADG under restricted feeding (-20% of ad libitum). The present study aimed to analyze the digestion and excretion of N and minerals from 29 to 63 d of age of these 2 lines compared with an unselected control line (G0) under 2 feeding levels (ad libitum or restricted). The ADGrestrict line had greater digestibility compared with G0 (+1.3% for OM and N; < 0.05), and the ConsoResidual line had intermediate values. There was no genetic line effect on the digestibility of N and P and on minerals concentrations (P, Zn, and Cu) in the feces and in the urine. The N balance was improved for the 2 selected lines (+5%; < 0.05), leading to a reduced N output through the feces (0.06 g/d compared with G0; < 0.001) and the urine (-0.07 g/d; < 0.05) and to an improved N retention ratio (+3% compared with G0). Over the whole fattening period (d 29-63), significant differences were observed among lines only when fed ad libitum, with 13% greater DM fecal output and 5% greater N fecal output for G0. The N excretion in urine was 2 g less in the 2 selected lines, leading to a reduction of total N release of 4.4 g (compared with G0). The P excretion in feces (12 g) or urine (0.1 g) did not differ among the 3 lines. Over the whole fattening period and for ad libitum-fed rabbits, the 5% improvement in feed efficiency ( < 0.01) for the 2 selected lines corresponded to 400 g less feed intake (-8%) and to 20 g less N intake. The fecal excretion of the ADGrestrict and ConsoResidual lines were reduced by 200 g DM ( < 0.01), corresponding to 417 g fresh matter and 5 g of N. The excretion in minerals (P, Zn, and Cu) was not affected by the line. The feeding level strongly reduced the fecal and urine outputs (-50 and -60%, respectively; < 0.001). Higher digestibility coefficients ( < 0.001) were found in restricted-fed rabbits for OM (+6%), N (+8%), and P (+11%). The N balance was substantially improved by the restriction, with 40% less total (feces + urine) N excretion ( < 0.001). The P balance was improved by the restriction (0.469 vs. 0.360). Over the fattening period, the P fecal output was 37% less (-6 g) with 24% less feed intake and the Zn and Cu outputs were reduced by 27 (-130 mg) and 29% (-30 mg), respectively.

Abstract
PURPOSE To evaluate the long-term functional outcomes after retropubic tension-free vaginal tape (TVT) placement to treat female stress urinary incontinence (SUI). METHODS From September 1998 to September 2000, we prospectively enrolled all consecutive women in our center suffering SUI caused by urethral hypermobility. All women had a retropubic TVT inserted by the same surgeon. Patients were evaluated at 1, 3, 6 and 12 months postoperatively, and annually thereafter. Postoperative assessment included a measurement of post-voiding residual volume, urinalysis, a 1-hour pad test, a urinary symptom questionnaire, and an assessment of quality-of-life. Objective continence (defined as no urine leakage at clinical examination) and subjective continence (defined as no urine leakage, whatever the mechanism, reported by the patient) were reported. RESULTS Overall, 58 consecutive women (median age 59; IQR 49-67; min 21-max 78) were evaluated. Median follow-up was 10.2years (IQR 1.4-16.0; min 1-max 13.2). At the last follow-up, objective and subjective continence rates were 93% and 78%, respectively and remained stable in the long run. Pad tests, urinary symptom questionnaire scores and quality-of-life were significantly improved. Self-intermittent catheterisation was required by three women. A section of one TVT and removal of another tape was undertaken in two women with chronic pelvic pain. One patient had a chronic urinary infection. Rate of de novo urgency was 10%. CONCLUSIONS TVT implantation offered good and stable functional long-term outcomes. This procedure enhanced quality-of-life and had low morbidity. LEVEL OF EVIDENCE 3.

Abstract
Elaphomyces ('deer truffles') is one of the most important ectomycorrhizal fungal genera in temperate and subarctic forest ecosystems, but also one of the least documented in public databases. The current systematics are mainly based on macromorphology, and is not significantly different from that proposed by Vittadini (1831). Within the 49 species recognised worldwide, 23 were originally described from Europe and 17 of these were described before the 20th century. Moreover, very recent phylogenetic treatments of the genus are mainly based on a few extra-European species and most common European species are still poorly documented. Based on an extensive taxonomic sampling mainly made in the biogeographically rich Cantabrian area (Spain), complemented with collections from France, Greece, Italy, Norway, Portugal and Sweden, all currently recognized species in Europe have been sequenced at the ITS and 28S of the rDNA. Combined phylogenetic analyses yielded molecular support to sections Elaphomyces and Ceratogaster (here emended), while a third, basal lineage encompasses the sections Malacodermei and Ascoscleroderma as well as the tropical genus Pseudotulostoma. Species limits are discussed and some taxa formerly proposed as genuine species based on morphology and biogeography are re-evaluated as varieties or forms. Spore size and ornamentation, features of the peridial surface, structure of the peridium, and the presence of mycelium patches attached to the peridial surface emerge as the most significant systematic characters. Four new species: E. barrioi, E. quercicola, E. roseolus and E. violaceoniger, one new variety: E. papillatus var. sulphureopallidus, and two new forms: E. granulatus forma pallidosporus and E. anthracinus forma talosporus are introduced, as well as four new combinations in the genus: E. muricatus var. reticulatus, E. muricatus var. variegatus, E. papillatus var. striatosporus and E. morettii var. cantabricus. Lectotypes and epitypes are designated for most recognised species. For systematic purposes, new infrageneric taxa are introduced: E. sect. Ascoscleroderma stat. nov., E. subsect. Sclerodermei stat. nov., E. subsect. Maculati subsect. nov., E. subsect. Muricati subsect. nov., and E. subsect. Papillati subsect. nov. Lastly, E.laevigatus, E. sapidus, E. sulphureopallidus and E. trappei are excluded from the genus and referred to Rhizopogon roseolus, Astraeus sapidus comb. nov., Astraeus hygrometricus and Terfezia trappei comb. nov. (syn.: Terfezia cistophila), respectively.

Abstract
Life-threatening cytokine release syndromes include primary (p) and secondary (s) forms of hemophagocytic lymphohistiocytosis (HLH). Below detection in healthy individuals, interferon γ (IFNγ) levels are elevated to measurable concentrations in these afflictions suggesting a central role for this cytokine in the development and maintenance of HLH. Mimicking an infection-driven model of sHLH in mice, we observed that the tissue-derived levels of IFNγ are actually 500- to 2000-fold higher than those measured in the blood. To identify a blood biomarker, we postulated that the IFNγ gene products, CXCL9 and CXCL10 would correlate with disease parameters in the mouse model. To translate this into a disease relevant biomarker, we investigated whether CXCL9 and CXCL10 levels correlated with disease activity in pediatric sHLH patients. Our data demonstrate that disease control in mice correlates with neutralization of IFNγ activity in tissues and that the 2 chemokines serve as serum biomarkers to reflect disease status. Importantly, CXCL9 and CXCL10 levels in pediatric sHLH were shown to correlate with key disease parameters and severity in these patients. Thus, the translatability of the IFNγ-biomarker correlates from mouse to human, advocating the use of serum CXCL9 or CXCL10 as a means to monitor total IFNγ activity in patients with sHLH.

Abstract
BACKGROUND Across the Africa region and beyond, the last decade has seen many countries introducing policies aimed at reducing financial barriers to obstetric care. This article provides evidence of the cost and effects of national policies focussed on improving financial access to caesarean and facility deliveries in Benin, Burkina Faso, Mali and Morocco. METHODS The study uses a comparative case study design with mixed methods, including realist evaluation components. This article presents results across 14 different data collection tools, used in 4-6 research sites in each of the four study countries over 2011-13. The methods included: document review; interviews with key informants; analysis of secondary data; structured extraction from medical files; cross-sectional surveys of patients and staff; interviews with patients and observation of care processes. RESULTS The article finds that the policies have contributed to continued increases in skilled birth attendance and caesarean sections and a narrowing of inequalities in all four countries, but these trends were already occurring so a shift cannot be attributed solely to the policies. It finds a significant reduction in financial burdens on households after the policy, suggesting that the financial protection objectives may have been met, at least in the short term, although none achieved total exemption of targeted costs. Policies are domestically financed and are potentially sustainable and efficient, and were relatively thoroughly implemented. Further, we find no evidence of negative effects on technical quality of care, or of unintended negative effects on untargeted services. CONCLUSIONS We conclude that the policies were effective in meeting financial protection goals and probably health and equity goals, at sustainable cost, but that a range of measures could increase their effectiveness and equity. These include broadening the exempted package (especially for those countries which focused on caesarean sections alone), better calibrated payments, clearer information on policies, better stewardship of the local health system to deal with underlying systemic weaknesses, more robust implementation of exemptions for indigents, and paying more attention to quality of care, especially for newborns.

Abstract
Although enteric viruses constitute a major cause of acute waterborne diseases worldwide, environmental data about occurrence and viral load of enteric viruses in water are not often available. In this study, enteric viruses (i.e., adenovirus, aichivirus, astrovirus, cosavirus, enterovirus, hepatitis A and E viruses, norovirus of genogroups I and II, rotavirus A and salivirus) were monitored in the Seine River and the origin of contamination was untangled. A total of 275 water samples were collected, twice a month for one year, from the river Seine, its tributaries and the major WWTP effluents in the Paris agglomeration. All water samples were negative for hepatitis A and E viruses. AdV, NVGI, NVGII and RV-A were the most prevalent and abundant populations in all water samples. The viral load and the detection frequency increased significantly between the samples collected the most upstream and the most downstream of the Paris urban area. The calculated viral fluxes demonstrated clearly the measurable impact of WWTP effluents on the viral contamination of the Seine River. The viral load was seasonal for almost all enteric viruses, in accordance with the gastroenteritis recordings provided by the French medical authorities. These results implied the existence of a close relationship between the health status of inhabitants and the viral contamination of WWTP effluents and consequently surface water contamination. Subsequently, the regular analysis of wastewater could serve as a proxy for the monitoring of the human viruses circulating in both a population and surface water.

Abstract
Lagomorpha (rabbits and pikas) and Sciuromorpha (squirrels) are grouped in the Glires superorder. Their chromosome diversification, since their separation from the eutherian mammalian common ancestor, was characterized by a low rate of chromosome rearrangements. Consequently, the structure of some chromosomes was either conserved or only slightly modified, making their comparison easy at the genus, family and even order level. Interspecific in situ hybridization (Zoo-FISH) largely corroborates classical cytogenetic data but provides much more reliability in comparisons, especially for distant species. We reconstructed common ancestral karyotypes for Glires, Lagomorpha, Sciuromorpha, and Sciuridae species, and then, determined the chromosome changes separating these ancestors from their common eutherian ancestor. We propose that reticulated evolution occurred during the diversification of Glires, which implies that several pericentric inversions and Robertsonian translocations were conserved in the heterozygous status for an extensive period. Finally, among Lagomorpha and Sciuromorpha, we focused on Leporidae and Sciuridae chromosome evolution. In the various attempts to establish dichotomic evolutionary schemes, it was necessary to admit that multiple homoplasies (convergent and reverse rearrangements) occurred in Sciuridae and in a lesser degree, in Leporidae. In Leporidae, additional rearrangements were sufficient to propose a resolved phylogeny. However, a resolved phylogeny was not possible for Sciuridae because most of the rearrangements occurred in terminal branches. We conclude that a reticulated evolution took place early during the evolution of both families and lasted longer in Sciuridae than in Leporidae. In Sciuridae, most chromosome rearrangements were pericentric inversions involving short fragments. Such rearrangements have only mild meiotic consequences, which may explain the long persistence of the heterozygous status characterizing reticulated evolution.

Abstract
OBJECTIVES Analyze the results of the bibliometric system and analysis of scientific publications (SIGAPS) in the Assistance publique-Hôpitaux de Paris (AP-HP) and compare the scientific production among the various surgical disciplines of the academic hospitals of Paris and define the place of urology. METHODS The publications from 115 surgical departments between 2006 and 2008 were included. Only surgical departments were considered in the current study. The following data were taken into account: the hospital department of origin, the number of articles published, the number of first place, last places, the number of full-time unit, the SIGAPS score. Statistical analysis focused on the quality and on the quantity of published articles per surgeons and per department. There were eight academic departments of urology identified within the AP-HP. RESULTS The database contained information for 115 surgical departments. The mean number of articles published by department was 42.89±27.34 (13.2 to 110.75). The mean number of publications per full-time surgeon was 6.7±2.59 (3.77 to 12.84), or a mean of 2.25±0.86 released by full-time and by year. The median score SIGAPS of surgery was 304 with a wide interval (122 to 903.5). Urology was the specialty with the highest median score compared to other surgical specialties. The department, which published the most, was the center 1, in comparison with the center 6 which was publishing the most in A/B ranking journals. CONCLUSION Urology was the absolute leader by far in terms of scientific publications in the AP-HP when compared to other surgical disciplines. The discipline is organized efficiently to juggle clinical work and research indicating a certain dynamism of the teams that invest there to fulfill the missions assigned to them in the University Hospital and the part of the autonomy of the universities.

Abstract
With the aim of limiting hospitalisation and a possible loss of autonomy, the paramedical team of the post-emergency and geriatric orientation unit at Nancy general hospital endeavours to anticipate the life programme as soon as the elderly patient arrives. A daily review and close collaboration with the social worker are key elements in the care.

Abstract
Fusions between individuals are a common feature of organisms with modular, indeterminate life forms, including plants, marine invertebrates and fungi. The consequences of fusion for an individual fungus are poorly understood. We used wild-type and fusion mutant strains of the genetic model Neurospora crassa to chronicle the fitness in two different laboratory habitats, and in each experiment started colonies from multiple different densities of asexual spores. On round Petri dishes, fusion enabled wild-type colonies to grow larger than mutant (soft) colonies; but in linear 'race tubes', the soft mutant always grew more quickly than the wild-type. Starting a colony with more spores always provided an advantage to a wild-type colony, but was more often neutral or a cost to the soft mutant. The ability to fuse does not provide a consistent advantage to wild-type colonies; net benefits are shaped by both habitat and initial spore densities.

Abstract
The first decade of the new millennium saw an upsurge in global financing for health. When the world took stock of progress on the Millennium Development Goals in mid-2010 the one addressing maternal health showed the least progress. Did maternal health miss the boat? In mid-2010 the Secretary-General of the United Nations launched a "Global Strategy for Women's and Children's Health", also known as the "Every Woman Every Child" initiative. Has the tide now turned in favour of maternal health? The authors try to answer this question by first examining whether maternal health really missed out with respect to increased global funding and why this may have occurred. They then assess whether the new initiative will make a difference by comparing several elements of the approach taken by HIV/AIDS activist to that of maternal health activists. They suggest that real progress requires international financing, thus pledges must become robust and reliable commitments. They conclude that the absence of an organisational structure in the current initiative means the global maternal health financing revolution will probably not happen.

Abstract
OBJECTIVE To report the functional results and morbidity after implantation of bulbar artificial urinary sphincter (AUS) in incontinent men with at least 5 years of follow-up. PATIENTS AND METHODS The files of patients treated between 1984 and 2003 by setting up a SAU at bulbar location were reviewed. The following data were recorded: age, etiology of incontinence, intra-operative complications. To evaluate the results on continence, patients were seen at 1, 3, 6 and 12 months, and yearly thereafter. RESULTS Overall, 159 men implanted with an AUS were included. The median age was 68.4 years and the median follow-up was 69 months. The etiology of incontinence was a prostate surgery in 83% of cases. The five-year rates of continence and satisfaction were 74.2% (n=118) and 92% (n=140), respectively. The five-year rates of infections and erosions were 4.4% and 9.4%, respectively. In case of previous radiotherapy, the rate of erosion at 5 years was 22.2%. The rate of atrophy and urethral mechanical failure at 5 years was 7.5% and 23.6%, respectively. The rate of reoperation at 5 years was 41.5%. CONCLUSION Our results confirm that the AUS is still the standard treatment for male with urinary incontinence due to intrinsic sphincter deficiency. Minimally invasive therapies are being developed that could overcome the mechanical failures and offer an alternative in case of primary or even secondary failure of the AUS.
