Study design: This consisted of a translation and validation study. Background: Acute hamstring injury is a frequent muscle strain in sports that require high explosive strength, impulsion or running phases. Therefore, the Functional Assessment Scale for Hamstring Injury questionnaire was developed to assess pain, physical activity level and ability to perform various exercises in patients with hamstring injuries. The Functional Assessment Scale for Hamstring Injury questionnaire is currently available in English, German, and Greek. Objectives: The goal of this study was to provide a cross-culturally adapted French-translation of the FASH questionnaire and to assess its psychometric performance. Methods: The French-translation and cross-cultural adaptation process were based on international recommendations, following six rigorous steps: (a) two initial translations from English to French; (b) synthesis of the two translations; (c) back-translations; (d) comparisons between the back-translations and the original questionnaire by an expert committee; (e) pretest; and (f) approval of the final French version of the Functional Assessment Scale for Hamstring Injury questionnaire. To validate this French version, 116 subjects (17 pathological patients, 19 patients with other muscle injury, 40 athletes at risk, and 40 healthy control athletes) were recruited to complete the Functional Assessment Scale for Hamstring Injury questionnaire. The Short Form Health Survey (SF-36) was used as a comparative questionnaire. The psychometric properties of the questionnaire were evaluated by determining the test-retest reliability after a 48–60-h interval, internal consistency, construct validity, and floor/ceiling effects. Results: All of the items of the Functional Assessment Scale for Hamstring Injury questionnaire were translated without any major difficulties. The questionnaire showed excellent discriminative power by obtaining significantly different scores from the four groups (p¼0.01). Regarding psychometric performances, the test–retest reliability was excellent (IntraClass Coefficient Correlation of 0.997). Very high internal consistency was also observed (Cronbach’s alpha of 0.969). Correlations with the physical health subscales of the SF-36 were significant and considered to be strong, indicating an excellent convergent validity. The other subscales of the SF-36 (mental health) were weakly correlated with the FASH, reflecting good divergent validity. No floor or ceiling effects were observed. Conclusion: The French-translation of the Functional Assessment Scale for Hamstring Injury questionnaire and its cross-cultural adaptation can be considered to be successful. Functional Assessment Scale for Hamstring Injury-French questionnaire is now a reliable and valid tool for patients suffering from acute hamstring injury, and its application in clinical practice is particularly relevant. IMPLICATIONS FOR REHABILITATION The FASH-F can be considered to be discriminant, reliable and valid for the evaluation of the severity of symptoms and sports ability in individuals with hamstring injuries. FASH-F is now a reliable and valid tool for French-speaking patients suffering from acute hamstring injury, and its application in clinical practice is particularly relevant. A limitation of our study could be that the distribution between the different study groups was not homogeneous implying that our findings may not be fully representative of the general population.

Workers may be exposed to pesticide residues when they enter an area that has been previously treated in order to realize different tasks (e.g. for pruning, cutting, picking, harvesting, pest scouting) or to handle a contaminated crop commodity (e.g. sorting, bundling, packing). A review of the scientific literature on workers exposed to pesticide residues during re-entry tasks provides a comprehensive view of possible exposure routes and a better understanding of the risk assessment context, threshold values and calculation methodology. Methods assessing the risk to workers health are also reported and discussed. The impact of re-entry activities on health and factors affecting workers exposure are examined. Finally, solutions and mitigation measures aiming to reduce their exposure to pesticide residues are recommended. [less ▲]

Leibniz’s conception of the relativity of motion has been discussed at length for a very long time. This paper doesn’t aim to give a full solution to this question, but to contribute to the debate by clarifying how the principle of relativity is introduced, justified and used in the Dynamica. Four different principles are identified : one purely geometrical, and three (meta)physical principles, which express God’s wisdom : a principle of equivalence of hypotheses linked to the action/reaction principle, a galilean principle of relativity and a general principle which apply not only to rectilinear motions but also to circular ones. I argue that to appreciate the coherence of Leibniz’ approach, we should distinguish these principles more sharply than he himself did and pay more attention to their status : are they consequences of the definition of motion, consequences of the physical laws or necessary conditions for any physical theory ?

Objectives: Behavioural activation improves mental health and psychological functioning, especially among patients with depression. Behavioural activation is associated with the improvement of several mechanisms, such as activation, avoidance, and environmental reward. Behavioural activation may also improve cognitive control abilities. Finally, studies on neurological changes suggested an improvement of the functioning of reward structures in response to positive stimuli after a BA treatment. Yet, uncertainty abounds regarding the putative mechanisms of behavioural activation. Prominent cognitive models of depression posit that attentional bias for negative and positive information may play an important role in the maintenance of a depressive mood. Inspired by these models and the results by the mentioned above, we investigated the impact of behavioural activation treatment for depression on attentional selectivity for sad and positive materials. We predicted that (1) attention to sad faces would be reduced after the intervention, (2) attention to happy faces would be enhanced after the intervention, and finally (3) the intervention would improve depressive symptomatology, activation, avoidance and environmental reward. Materials and method: Eight undergraduate students with medium to moderate depressive symptoms participated in a six-week behavioural activation intervention. A dot-probe task with happy and sad faces and self-report questionnaires focused on depression, activation, avoidance, and environmental reward were administered before and after the intervention. Results: Depression, avoidance, and environmental reward scores improved after treatment with large effect sizes. Behavioural activation likewise improves attentional bias for positive faces. However, there was no attentional bias for sad faces at either evaluation time. Conclusion: The preliminary nature of our findings notwithstanding, this study is the first to provide evidence of behavioural activation impact on attentional selectivity vis-à-vis positive material.

Mon objectif est de soumettre le concept de « pathologies de la liberté » à triple épreuve. 1/ à travers le célèbre conflit historique de la psychiatrie française opposant Henri Ey à Jacques Lacan sur la présence de la liberté au sein de la maladie mentale ; 2/ à travers l’opposition que nous identifierons entre les méthodes prônées par Binswanger et par Minkowski pour réaliser une compréhension psychopathologique de l’individu ; 3/ à travers la clinique, le cas Germain, patient psychotique dont nous reprendrons l’histoire qui le verra s’opposer au monde entier. Je donnerai différents arguments en analysant ces débats (historiques, méthodologiques et cliniques) afin de proposer une lecture singulière des pathologies de la liberté et de voir comment cette lecture s’inscrit dans le champ psychopathologique. L’objectif de ma contribution sera de rencontrer le vécu en première personne du sujet psychotique qui se retrouve mal dans la qualification de son existence comme étant privée de liberté. Comme le titre de cette étude l’annonce, la thèse que je défends est de considérer que l’interrogation des pathologies de la liberté conduit également à interroger son corollaire, la dimension inéluctablement libre inhérente aux personnes affectées de psychopathologies. Ce décalage, que nous permettra d’entrevoir Lacan, nous mènera à interroger la dimension adaptative de l’expérience psychopathologique et, dans la continuité de Canguilhem, à considérer la pathologie comme la création de normes inédites (généralement inaccessibles à autrui).

Renommée depuis la plus haute antiquité pour son ancienneté et son excellence, la médecine égyptienne a-t-elle pu influencer la médecine occidentale et, si tel est le cas, en quoi et de quelle manière ? Que s’est-il passé lorsque la médecine grecque héritée d'Hippocrate a été importée en Égypte à la suite de la conquête du pays par Alexandre le Grand, en 332 avant notre ère ? Après avoir comparé les écrits médicaux égyptiens et grecs et les pratiques médicales attestées dans le Pays du Nil et dans le monde hellénique, on examinera, à côté des sources littéraires qui font de l' « école médicale d'Alexandrie » un modèle qui restera pour longtemps inégalé, les papyrus médicaux grecs (des IVe/IIIe siècles avant notre ère au VIIe siècle de notre ère), retrouvés en nombre sans cesse croissant dans les sables égyptiens, ainsi que d'autres sources archéologiques, en vue de répondre à ces questions.

When polymer mixtures become increasingly complex, the conventional analysis techniques become insufficient for complete characterization. Mass spectrometric techniques can satisfy this increasing demand for detailed sample characterization. Even though isobaric polymers are indistinguishable using simple mass spectrometry (MS) analyses, more advanced techniques such as tandem MS (MS/MS) or ion mobility (IM) can be used. Here, we report proof of concept for characterizing isomeric polymers, namely poly(2-n-propyl-2-oxazoline) (Pn-PrOx) and poly(2-isopropyl-2-oxazoline) (Pi-PrOx), using MS/MS and IM-MS. Pi-PrOx ions lose in intensity at higher accelerating voltages than Pn-PrOx ions during collision-induced dissociation (CID) MS/MS experiments. A Pn/i-PrOx mixture could also be titrated using survival yield calculations of either precursor ions or cation ejection species. IM-MS yielded shape differences in the degree of polymerization (DP) regions showing the structural rearrangements. Combined MS techniques are thus able to identify and deconvolute the molar mass distributions of the two isomers in a mixture. Finally, the MS/MS and IM-MS behaviors are compared for interpretation.

We hypothesized that the active targeting of αvβ3 integrin overexpressed in neoangiogenic blood vessels and glioblastoma (GBM) cells combined with magnetic targeting of paclitaxel- and SPIO-loaded PLGA-based nanoparticles could improve accumulation of nanoparticles in the tumor and therefore improve the treatment of GBM. Methods: PTX/SPIO PLGA nanoparticles with or without RGD-grafting were characterized. Their in vitro cellular uptake and cytotoxicity was evaluated by fluorospectroscopy and MTT assay. In vivo safety and anti-tumor efficacy of different targeting strategies was evaluated in orthotopic U87MG tumor model over multiple intravenous injections. Results: The nanoparticles of 250nm were negatively charged. RGD targeted nanoparticles showed a specific and higher cellular uptake than untargeted nanoparticles by activated U87MG and HUVEC cells. In vitro IC50 of PTX after 48h was approximately 1 ng/mL for all the PTX-loaded nanoparticles. The median survival time of the mice treated with magnetic targeted nanoparticles was higher than the control (saline) mice or mice treated with other evaluated strategies. The 6 doses of PTX did not induce any detectable toxic effects on liver, kidney and heart when compared to Taxol. Conclusion. The magnetic targeting strategy resulted in better therapeutic effect than the other targeting strategies (passive, active). [less ▲]

Seasonal timing of reproduction is a key life-history trait, but we know little about the mechanisms underlying individual variation in female endocrine profiles associated with reproduction. In birds, 17b-oestradiol is a key repro- ductive hormone that links brain neuroendocrine mechanisms, involved in information processing and decision-making, to downstream mechanisms in the liver, where egg-yolk is produced. Here, we test, using a simulated induction of the reproductive system through a GnRH challenge, whether the ovary of pre-breeding female great tits responds to a brain stimulation by increasing oestradiol. We also assess how this response is modified by individual-specific traits like age, ovarian follicle size and personality, using females from lines artificially selected for divergent levels of explora- tory behaviour. We show that a GnRH injection leads to a rapid increase in circulating concentrations of oestradiol, but responses varied among individ- uals. Females with more developed ovarian follicles showed stronger responses and females from lines selected for fast exploratory behaviour showed stronger increases compared to females from the slow line, indicat- ing a heritable component. This study shows that the response of the ovary to a reproductive stimulation from the brain greatly varies among individ- uals and that this variation can be attributed to several commonly measured individual traits, which sheds light on the mechanisms shaping heritable endocrine phenotypes.

The competences expected from early childhood education and care professionals have evolved significantly in our Western countries following the transformation of services and the affirmation of their educational function. This article is based on action research projects carried out in the Wallonia Brussels Federation (FWB) which integrate an analysis of other education and training systems (France, Flanders, England, Sweden and Quebec). It presents a reflection on the development of professional competencies and their acquisition from the initial training in a holistic approach to education. It notes that a diversity of formations coexists, leading to an absence of clear view on professional skills and profiles. In response to this observation, it proposes a modeling that articulates organizational, relational and reflexive competencies that are needed for the development of a professional posture. That modeling is presented as a grid of analysis that can enable better understanding of the complexity of early education and care in its many dimensions (working with children, families, professionals and the local community). It can be considered as a tool to globally rethink initial and continuing education and training in a systemic perspective. [less ▲]

After hematopoietic stem cell transplantation (HCT), many patients present anemia, which can persist for months due to an inadequate Epo production for the degree of the anemia. In this thesis, we performed two randomized studies with erythropoiesis-stimulating agents (ESA) therapy after allogeneic (including myeloablative and non-myeloablative conditioning) and autologous transplantation. We showed a great efficacy of this growth factor to ensure full erythroid reconstitution when initiated soon after engraftment, and not immediately after the transplant. Furthermore, as iron parameters are quite disturbed following HCT, we sought to study iron metabolism after HCT (which has not been much investigated), integrating the role of hepcidin, the key regulator in iron metabolism. Hence, we demonstrated that hepcidin levels prior to and following autologous HCT were influenced by iron stores and changes in erythropoietic activity [less ▲]

Platelet-rich plasma (PRP) is increasingly used in the treatment of musculoskeletal diseases. Its preservation by freezing it for the realization of multiple injections in clinical use has never been discussed. Calcaneal tendons of rats were surgically sectioned. Platelet concentration of the PRP was 2.5 x 106/μl with autologous plasma of rats. Frozen-thawed PRP was prepared by performing two cycles of freezing and thawing on PRP aliquots. Both platelet preparations were injected in the lesion. Biomechanical and histological evaluations were carried out after 7, 20 or 40 days post surgery. After 7 and 40 days, no significant difference was observed between the PRP and the frozen-thawed PRP group. There is however a difference 20 days after surgery: the ultimate tensile strength (UTS) was greater in the fresh PRP group. No obvious difference with histological aspect was observed between the two groups. In conclusion, fresh PRP and frozen-thawed PRP injections can lead to similar results in the healing process of section calcaneal tendons of rats. Improvements with fresh PRP are slight. PRP could thus be frozen to be preserved if multiple injections are needed (e.g. osteoarthritis). [less ▲]

WVO Quine questions the « myth » of an ideal realm of shared meanings which every national language would express in its own way. Against the hope of transparent translations, he insists on the necessity for building equivalences from one language to another through a strategy of reducing the differences in rationality among nations as much as possible. According to Quine, otherness is not insuperable impediment to meeting/encounter and mutual understanding ; by throwing our conceptual schemes on the other communities’ uses/practices – which of course involves some symbolic violence – gaps can always been narrowed. Similarly E. Laclau questions the traditional conception of political representation, which is seen as the transparent process of transmitting someone’s will or interests on another level. For this ideal conception of representation, Laclau substitutes a pragmatic conception which takes in account the irreducible gap between the actors as well as the constitutive opacity of the process of representation : the subject’s will is constituted within the process of representation and through the representative’s productive role. In order to be transposed at the decision-making level, the subject’s interests must be translated by the representative as well as be negotiated with the other represented interests. This implies that the initial will undergoes some identity transformations. [less ▲]

A classification for peri-implant diseases and conditions was presented. Focused questions on the characteristics of peri-implant health, peri-implant mucositis, periimplantitis, and soft- and hard-tissue deficiencies were addressed. Peri-implant health is characterized by the absence of erythema, bleeding on probing, swelling, and suppuration. It is not possible to define a range of probing depths compatible with health; of more importance are the clinical signs of inflammation. Peri-implant health can exist around implants with reduced bone support.The main clinical characteristic of peri-implant mucositis is bleeding on gentle probing. Erythema, swelling, and/or suppuration may also be present. An increase in probing depth is often observed in the presence of peri-implant mucositis due to swelling or decrease in probing resistance. There is strong evidence from animal and human experimental studies that plaque is the etiological factor for peri-implant mucositis. Peri-implantitis is a plaque-associated pathological condition occurring in tissues around dental implants, characterized by inflammation in the peri-implant mucosa and subsequent progressive loss of supporting bone. Peri-implantitis sites exhibit clinical signs of inflammation, bleeding on probing, and/or suppuration, increased probing depths and/or recession of the mucosal margin in addition to radiographic bone loss. The evidence is equivocal regarding the effect of keratinized mucosa on the longterm health of the peri-implant tissue. It appears, however, that keratinized mucosa may have advantages regarding patient comfort and ease of plaque removal. Case definitions in day-to-day clinical practice and in epidemiological or diseasesurveillance studies for peri-implant health, peri-implant mucositis, and periimplantitis were introduced. The proposed case definitions should be viewed within the context that there is no generic implant and that there are numerous implant designs with different surface characteristics, surgical and loading protocols. It is recommended that the clinician obtain baseline radiographic and probing measurements following the completion of the implant-supported prosthesis. [less ▲]

Linking interindividual differences in psychological phenotype to variations in brain structure is an old dream for psychology and a crucial question for cognitive neurosciences. Yet, replicability of the previously-reported “structural brain behavior” (SBB)-associations has been questioned, recently. Here, we conducted an empirical investigation, assessing replicability of SBB among heathy adults. For a wide range of psychological measures, the replicability of associations with gray matter volume was assessed. Our results revealed that among healthy individuals 1) finding an association between performance at standard psychological tests and brain morphology is relatively unlikely 2) significant associations, found using an exploratory approach, have overestimated effect sizes and 3) can hardly be replicated in an independent sample. After considering factors such as sample size and comparing our findings with more replicable SBB-associations in a clinical cohort and replicable associations between brain structure and non-psychological phenotype, we discuss the potential causes and consequences of these findings.

Poly(vinyl alcohol) (PVA) and poly(vinyl amine) (PVAm) are major industrial polymers involved in countless applications taking advantage of their ability to establish hydrogen bonds and, for the latter, to create charges along the polymer’s backbone upon protonation. Although combining vinyl alcohol and vinyl amine units in specific proportions within copolymers should allow precise tuning of their properties and enlarge the scope of their use, the controlled synthesis of poly(VAm-co-VA)s has been completely dis- regarded so far. In this context, we report a straightforward strategy for preparing the aforementioned copolymers via cobalt-mediated radical copolymerization of vinyl acetate (VAc) and vinyl acetamide (NVA) followed by hydrolysis. Copolymerization conditions were optimized to produce poly(NVA-co-VAc) with predictable molar mass, low dispersity and precise composition. Reactivity ratios were also determined to gain insight into the distribution of the amine and alcohol moieties along the backbone. Depending on the hydrolysis treatment applied to poly(NVA-co-VAc), unprecedented well-defined poly(VAm-co-VA)s and poly(NVA-co-VA)s were achieved via full deprotection of the precursor and selective hydrolysis of its esters, respectively.

In male songbirds, the motivation to sing is largely regulated by testosterone action in the medial preoptic area, whereas testosterone acts on song control nuclei to modulate aspects of song quality. Stereotaxic implantation of testosterone in the medial preoptic nucleus (POM) of castrated male canaries activates a high rate of singing activity, albeit with a longer latency than after systemic testosterone treatment. Systemic testosterone also increases the occurrence of male-like song in female canaries. We hypothesized that this effect is also mediated by testosterone action in the POM. Females were stereotaxically implanted with either testosterone or with estradiol targeted at the POM and their singing activity was recorded daily during 2 hours for 28 days until brains were collected for histological analyses. Following identification of implant localizations, 3 groups of subjects were constituted that had either testosterone or estradiol implanted in the POM or had an implant that had missed the POM (Out). Testosterone and estradiol in POM significantly increased the number of songs produced and the percentage of time spent singing as compared with the Out group. The songs produced were in general of a short duration and of poor quality. This effect was not associated with an increase in HVC volume as observed in males, but testosterone in POM enhanced neurogenesis in HVC, as reflected by an increased density of doublecortin-immunoreactive multipolar neurons. These data indicate that, in female canaries, testosterone acting in the POM plays a significant role in hormone-induced increases in the motivation to sing. [less ▲]

Disorders of consciousness (DOC) are a common consequence of severe brain injuries, and clinical evaluation is critical to provide a correct diagnosis and prognosis. The revised Motor Behavior Tool (MBT-r) is a clinical complementary tool aiming to identify subtle motor behaviors that might reflect residual cognition in DOC. In this prospective study including 30 DOC patients in the early stage after brain injury, we show that the revised MBT-r has an excellent inter-rater agreement and has the ability to identify a subgroup of patients, underestimated by the Coma Recovery Scale-Revised, showing residual cognition and a subsequent recovery of consciousness.

Aside from modeling geometric shape, three-dimensional (3D) urban procedural modeling has shown its value in understanding, predicting and/or controlling effects of shape on design and urban planning. In this paper, instead of the construction of flood resistant measures, we create a procedural generation system for designing urban layouts that passively reduce water depth during a flooding scenario. Our tool enables exploring designs that passively lower flood depth everywhere or mostly in chosen key areas. Our approach tightly integrates a hydraulic model and a parameterized urban generation system with an optimization engine so as to find the least cost modification to an initial urban layout design. Further, due to the computational cost of a fluid simulation, we train neural networks to assist with accelerating the design process. We have applied our system to several real-world locations and have obtained improved 3D urban models in just a few seconds. [less ▲]

A clinical case in Belgium demonstrated that feeding a feed concentrate containing considerable levels of deoxynivalenol (DON, 1.13 mg/kg feed) induced severe liver failure in 2- to 3-month-old beef calves. Symptoms disappeared by replacing the highly contaminated corn and by stimulating ruminal development via roughage administration. A multi-mycotoxin contamination was demonstrated in feed samples collected at 15 different veal farms in Belgium. DON was most prevalent, contaminating 80% of the roughage samples (mixed straw and maize silage; average concentration in positives: 637 +/- 621 microg/kg, max. 1818 microg/kg), and all feed concentrate samples (411 +/- 156 microg/kg, max. 693 microg/kg). In order to evaluate the impact of roughage provision and its associated ruminal development on the gastro-intestinal absorption and biodegradation of DON and its acetylated derivatives (3- and 15-ADON) in calves, a toxicokinetic study was performed with two ruminating and two non-ruminating male calves. Animals received in succession a bolus of DON (120 microg/kg bodyweight (BW)), 15-ADON (50 microg/kg BW), and 3-ADON (25 microg/kg) by intravenous (IV) injection or per os (PO) in a cross-over design. The absolute oral bioavailability of DON was much higher in non-ruminating calves (50.7 +/- 33.0%) compared to ruminating calves (4.1 +/- 4.5%). Immediately following exposure, 3- and 15-ADON were hydrolysed to DON in ruminating calves. DON and its acetylated metabolites were mainly metabolized to DON-3-glucuronide, however, also small amounts of DON-15-glucuronide were detected in urine. DON degradation to deepoxy-DON (DOM-1) was only observed to a relevant extent in ruminating calves. Consequently, toxicity of DON in calves is closely related to roughage provision and the associated stage of ruminal development. [less ▲]

Quantifying carbon dynamics in forests is critical for understanding their role in long-term climate regulation1–4. Yet little is known about tree longevity in tropical forests3,5–8, a factor that is vital for estimating carbon persistence3,4. Here we calculate mean carbon age (the period that carbon is fixed in trees7) in different strata of African tropical forests using (1) growthring records with a unique timestamp accurately demarcating 66 years of growth in one site and (2) measurements of diameter increments from the African Tropical Rainforest Observation Network (23 sites). We find that in spite of their much smaller size, in understory trees mean carbon age (74 years) is greater than in sub-canopy (54 years) and canopy (57 years) trees and similar to carbon age in emergent trees (66 years). The remarkable carbon longevity in the understory results from slow and aperiodic growth as an adaptation to limited resource availability9–11. Our analysis also reveals that while the understory represents a small share (11%) of the carbon stock12,13, it contributes disproportionally to the forest carbon sink (20%). We conclude that accounting for the diversity of carbon age and carbon sequestration among different forest strata is critical for effective conservation management14–16 and for accurate modelling of carbon cycling4.

Background The financial impact associated with drug consumption has been poorly investigated among frail subjects and, specifically, in nursing home settings. Aims To determine the association of the average monthly cost of the drugs and dietary supplements consumed by nursing home residents with their frailty status. Methods This is an analysis of the first follow-up year of the SENIOR cohort. All participants were classified into “frail” or “non-frail” categories according to Fried’s criteria at baseline. Monthly bills from the pharmacy were analysed to determine the association between the average monthly cost of the drugs and dietary supplements consumed and frailty status. Results A sample of 87 residents (83.8 ± 9.33 years and 75.9% women) from the SENIOR cohort was included. The prevalence of frailty was 28%. The median number of medications consumed each day was 9 (6–12) (no difference between frail and non-frail subjects; p = 0.15). The overall median monthly cost was € 109.6, of which 49% was covered by Belgian social security and the remaining balance was paid by the patient. When comparing the drug expenses of the frail subjects and the non-frail subjects, the overall average monthly cost did not differ between the 2 groups (p = 0.057). Nevertheless, the expenditure remaining to be paid by the residents, after the Belgian social security intervention, was significantly higher among the frail residents (€ 65.7) than among the non-frail residents (€ 47.6; p = 0.017). Conclusions Frailty status has an impact on the expenditures related to the consumption of drugs. [less ▲]

BACKGROUND:Considerable differences exist among the living donor Kidney Exchange Programmes (KEPs) that are in use and being built in Europe, contributing to a variation in the number of living donor transplants [6]. Efforts of European KEPs to exchange (best) practices and share approaches to address challenges have, however, been limited.METHODS:Experts from 23 European countries, collaborating on the ENCKEP COST Action, developed a questionnaire to collect detailed information on the functioning of all existing KEPs in Europe, as well as their opportunities and challenges. Following a comparative analysis, results were synthesised and interpreted by the same experts.RESULTS:The practices, opportunities and challenges reported by 17 European countries reveal that some of the 10 operating programmes are mature, while others are in earlier stages of development. Over 1300 transplants were performed through existing KEPs up to the end of 2016, providing approximately 8\% of their countries' living kidney donations in 2015. All countries report challenges to either initiating KEPs or increasing volumes. Some challenges are shared, whilst others differ because of differences in context (eg, country size, effectiveness of deceased donor programme) and ethical and legal considerations (eg, regarding living donation as such, nonrelated donors, and altruistic donation). Transnational initiatives have started in Central Europe, Scandinavia, and Southern Europe.CONCLUSIONS:Exchange of best practices and shared advancement of national programmes to address existing challenges, aided by transnational exchanges, may substantially improve access to the most (cost) effective treatment for the increasing number of patients suffering from kidney disease.This is an open access article distributed under the Creative Commons Attribution License 4.0 (CCBY), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.

Les troubles du spectre autistique comportent des comorbidités multiples, dont des altérations du sommeil. Ils sont importants à caractériser dans cette population, car ils peuvent avoir un impact négatif sur les comportements diurnes. Par ailleurs, ils entrainent souvent des difficultés au sein de la famille.

This article focuses on technologies of mobility for people with physical disabilities living in a South African poor urban setting. It moves away from a perspective that exposes limitations to underline specific opportunities for people with disabilities to design the city. In the township of Mitchell’s Plain (Cape Town), known for its violence, defining when and where to use the chair involves a negotiation of moral and medical norms with a pursuit of security. In this process, the wheelchair constitutes one element of a larger continuum of wheeled mobility. The availability of public and private alternative transport enhances already present inequalities among people with disabilities. Two systems of public transport are further discussed, namely Dial-a-Ride (a specialized transport) and MyCiTi bus (a mainstream service). Initiatives of the City of Cape Town, these transports are widely discussed and criticized by people with disabilities. Through discussion with or opposition to the local government, associations participate actively in their inclusion in the post-apartheid city. My conclusions, drawn upon nineteen months of ethnographic fieldwork, call upon the theoretical framework of the anthropology of material things and the sociology of space. [less ▲]

OBJECTIVES: Type 2 diabetes mellitus (T2DM) and osteoarthritis (OA) are common diseases that frequently co-exist, along with overweight/obesity. While the mechanical impact of excess body weight on joints may explain lower limb OA, we sought to explore whether T2DM is linked to OA outside of excess weight and whether T2DM may play a role in OA pathophysiology. The consequence of T2DM on OA outcomes is a question of research interest. METHODS: We conducted a critical review of the literature to explore the association between T2DM and OA, whether any association is site-specific for OA, and whether the presence of T2DM impacts on OA outcomes. We also reviewed the literature to assess the safety of anti-OA treatments in patients with T2DM. RESULTS: T2DM has a pathogenic effect on OA through 2 major pathways involving oxidative stress and low-grade chronic inflammation resulting from chronic hyperglycemia and insulin resistance. T2DM is a risk factor for OA progression and has a negative impact on arthroplasty outcomes. Evidence is mounting for safety concerns with some of the most frequently prescribed anti-OA medications, including paracetamol, non-steroidal anti-inflammatory drugs, and corticosteroid injections, while other anti-OA medications may be safely prescribed in OA patients with T2DM, such as glucosamine and intra-articular hyaluronic acid. CONCLUSIONS: Future research is needed to better understand whether diabetes control and prevention can modulate OA occurrence and progression. The selection of therapy to treat OA symptoms in patients with T2DM may require careful consideration of the evidence based to avoid untoward safety issues. [less ▲]

Resolving population genetic structure is challenging, especially when dealing with closely related populations. Although Principal Component Analysis (PCA)-based methods and genomic var- iation with single nucleotide polymorphisms (SNPs) are widely used to describe shared genetic an- cestry, improvements can be made targeting fine-level population structure. This work presents an R package called IPCAPS, which uses SNP information for resolving possibly fine-level population structure. The IPCAPS routines are built on the iterative pruning Principal Component Analysis (ipP- CA) framework to systematically assign individuals to genetically similar subgroups. Our tool is able to detect and eliminate outliers in each iteration to avoid misclassification. It can be extended to de- tect subtle subgrouping in patients as well. In addition, IPCAPS supports different measurement scales for variables used to identify substructure. Hence, panels of gene expression and methylation data can be accommodated. [less ▲]

In A New World Order (2001) Caryl Phillips claims that “every writer discovers that his or her main struggle is with this one world: form” (293). His struggle with form bears on questions such as how to write about unbearably painful lives, how to mirror the trauma undergone by his characters, or how to speak about the unspeakable. Phillips seems to have found a stylistic device enabling him to offer the readers a sense of his characters’ traumatic experience and mirror their emotional state: the musicalization of his prose. Phillips’s use of what I call musical writing is striking in his 1997 novel The Nature of Blood, especially in the sections devoted to Eva. This essay offers an interpretation of Phillips’s musical prose through close readings of Eva’s story and explores how the author’s musical stylization can also reflect the two different ways of approaching traumatic experience suggested by Dominick LaCapra’s: “acting out” and “working through” (Writing 21–2, History 54,104). This piece also shows how through stylistic devices akin to music Phillips resorts to a language which both seeks and defies the reader’s understanding, thereby avoiding any easy identification with Eva.

Highly cross-linked polyethylene is currently a common articulation surface used for THA. The aim of the present study is in-vivo assessment of highly cross-linked Durasul® polyethylene linear and volumetric wear when associated with a 36-mm prosthetic femoral head. We retrospectively reviewed clinical and radiographic data of 78 patients (81 hips) having primary THAs using Durasul® liner combined with a 36-mm CoCr prosthetic head. All of them were followed for more than 10 years. Patient outcome was assessed with the Harris Hip Score (HHS) preoperatively and at last follow-up. Two-dimensional prosthetic head penetration into polyethylene, three-dimensional wear rates and cup migration were evaluated. the preoperative and last follow-up HHS were 50.43 +/- 10.42 and 97.44 +/- 5.51 respectively. The annual penetration of the prosthetic head into Durasul® liner was 0.029 +/- 0.003 mm. The annual linear penetration and volumetric wear extrapolation rates using Charnley and Ilchmann formulas were 37.84% and 57.76% respectively of that seen with conventional polyethylene liner. At last follow-up, the total loss of material in Durasul® represents only 0.15% of the initial polyethylene mass. We did not observed any significant cup migration in the study group. Results are promising and we believe that these data authorize the continued use of highly cross-linked polyethylene liner associated with a 36-mm prosthetic head for total hip arthroplasties in older patients. More long-term follow-up studies are mandatory before we feel comfortable with the project of using cross-linked polyethylene in young and active patients instead of ceramic-on-ceramic bearings.

This paper seeks to shed light on the diversity of scaling strategies of social enterprises, which can be considered as emblematic hybrid organizations. By comparing three Flemish renewable energy cooperatives with contrasted scaling strategies, the paper shows how these strategies can be understood in relation to the organizational mission as imprinted at the founding. We extend the notion of hybridity beyond the combination of institutional logics to highlight the interest orientation (mutual versus general interest). Unlike what is suggested in extant literature, we find that mutual interest orientation may be associated with ‘scale up’, business growth strategies, while general interest orientation may lead to less growth-focused ‘scale out’ and ‘scale deep’ strategies. The findings illuminate aspects of the hybrid nature of social enterprises by explaining their diverse scaling strategies, and extend the notion of imprinting to the inter-organizational level by highlighting how social enterprises may collaborate to collectively achieve the pursuit of their multiple missions.

The skeletal effects of renal transplantation are not completely understood, especially in patients managed with a steroid minimization immunosuppressive protocol and long term. We enrolled 69 adult transplant recipients (39 males; ages 51.1 +/- 12.2 years), free of antiresorptive therapy and managed with a steroid minimization immunosuppressive protocol, into a 5-year prospective observational study to evaluate changes in areal bone mineral density (aBMD), mineral metabolism and bone remodelling. Dual energy X-ray absorptiometry, laboratory parameters of mineral metabolism (including parathyroid hormone, sclerostin and fibroblast growth factor 23) and non-renal cleared bone turnover markers (BTMs) (bone-specific alkaline phosphatase, trimeric N-terminal propeptide and tartrate-resistant acid phosphatase 5b) were assessed at baseline and 1 and 5 years post-transplantation. The mean cumulative methylprednisolone exposure at 1 and 5 years amounted to 2.5 +/- 0.8 and 5.8 +/- 3.3 g, respectively. Overall, bone remodelling activity decreased after transplantation. Post-transplant aBMD changes were minimal and were significant only in the ultradistal radius during the first post-operative year {median -2.2% [interquartile range (IQR) -5.9-1.2] decline, P = 0.01} and in the lumbar spine between Years 1 and 5 [median 1.6% (IQR -3.2-7.0) increase, P = 0.009]. BTMs, as opposed to mineral metabolism parameters and cumulative corticosteroid exposure, associated with aBMD changes, both in the early and late post-transplant period. Most notably, aBMD changes inversely associated with bone remodelling changes. In summary, in de novo renal transplant recipients treated with a steroid minimization immunosuppressive protocol, BMD changes are limited, highly variable and related to remodelling activity rather than corticosteroid exposure.

Co-production of water and sanitation services, especially in the global South, implies that recipients of a service play a fundamental role in managing water resources. In the context of citizen–government synergies, service recipients are more than consumers, and (co)-production alters their involvement in the service production process, with respect to their relationships with both the natural resources and the delivery process. Our hypothesis is that a meaningful understanding of co- production for water and sanitation services is only possible through an interdisciplinary approach that takes into account natural and social dimensions. The objective is to develop a possible new conceptualization of service co-production that can foster a renewed citizenship while taking into account the risks of urban fragmentation. [less ▲]

This paper studies individuals’ preference for reducing advantageous inequality in the distribution of gains and losses. Combining the inequality aversion model of Fehr and Schmidt (Q J Econ 114(3):817–868, 1999) with loss aversion à la Kahneman and Tversky (Econom J Econom Soc:263–291, 1979), we predict the relative dislike for advantageous inequality is lower when outcomes are framed as losses than when outcomes are framed as gains. We test this prediction using data from two modified dictator game experiments. Consistent with the model, we find that the amount of payoff that subjects are willing to sacrifice to increase the net payoff of others and reduce advantageous inequality is smaller under a loss frame than under a gain frame. The results also show that women are more inequality averse than men in both gains and losses. [less ▲]

Analyses of hydrological impacts of climate change require appropriate methods for perturbing meteoric time-series to represent future climate conditions. Two readily available tools for perturbing rainfalls and temperatures are tested for a medium-sized catchment in Belgium. CCI-HYDR provides three scenarios, tailored for Belgium every decade until 2100. In contrast, KNMI-ADC tool provides 191 scenarios, at a regional level and for two horizons (near and far future). With its three contrasted scenarios of possible future climate conditions, CCI-HYDR is found suitable for forcing computationally intensive detailed hydrological models. With its broader spectrum of climate scenarios, KNMI-ADC tool is suitable for forcing multiple runs of fast conceptual hydrological models. As the two perturbation tools deliver stationary time-series, they are also compared to an alternate method producing transient time-series. Transient stochastic tools are particularly computationally demanding due to their stochastic nature, which is not optimal when combined with detailed distributed hydrological models. [less ▲]

La démocratie reste un thème chéri par la philosophie politique contemporaine, pour l’écart entre ses théories et ses pratiques, pour la distance critique que ses théories offrent vis-à-vis des régimes démocratiques et de leur évolution, mais aussi parce qu’elle est un objet perpétuel de dissensus entre philosophes, au sujet duquel toute prétention à la véridiction est suspendue à sa réalisation pratique. À ce titre, la transmission de la volonté démocratique est un topos houleux de la philosophie politique contemporaine. Cette question catalyse les concepts pivots des philosophies politiques, la leur poser permet de mieux saisir les enjeux rivaux derrière une terminologie commune à plusieurs auteurs. C’est dans cette démarche que je vous propose d’examiner en miroir les philosophies de Cornélius Castoriadis et de Jacques Rancière. De plus en plus nombreux, des commentateurs rapprochent leurs pensées , qui peuvent s’appuyer sur plusieurs points communs : un attachement au concept de démocratie brandit contre les régimes parlementaires, une opposition contemporaine (quoique depuis des héritages différents) aux thèses défendues par Althusser, et une proximité de sources d’inspirations : la philosophie, le marxisme, et la psychanalyse. Partant de la manière dont cette proximité s’exprime dans la disjonction que chacun opère entre démocratie et science, je tenterai de discerner comment les inflexions qu’ils impriment aux concepts de volonté et d’égalité sous la guise des enjeux de la transmission dessinent des horizons politiques distincts, et dénotent des compréhensions antithétiques – mais indécidables dans la théorie – de ce que peut être la démocratie.

Although old molecules, alkylating agents and platinum derivatives are still widely used in the treatment of various solid tumors. However, systemic toxicity and cellular resistance mechanisms impede their efficacy. Innovative strategies, including local administration, optimization of treatment schedule/ dosage, synergistic combinations, and the encapsulation of bioactive mole- cules in smart, multifunctional drug delivery systems, have shown promising results in potentiating anticancer activity while circumventing such hurdles. Furthermore, questioning of the old paradigm according to which nuclear DNA is the critical target of their anticancer activity has shed light on subcellular alternative and neglected targets that obviously participate in the mediation of cytotoxicity or resistance. Thus, rethinking of the use of these pivotal anti- neoplastic agents appears critical to improve clinical outcomes in the management of solid tumors. [less ▲]

Dans l’une de ses conversations avec Joachim Gasquet sur le sens de sa peinture (et de la peinture en général), Cézanne aborde de front la conception qu’il se fait de la couleur, dans son rapport à la profondeur picturale et de son articulation à la surface : « La nature n'est pas en surface ; elle est en profondeur. Les couleurs sont l'expression, à cette surface, de cette profondeur. Elles montent des racines du monde ». Cet « organisme de couleurs » que constitue le monde est transcrit dans la peinture de Cézanne par une dynamique symbiotique de la couleur et du dessin, de la ligne et du pan. La couleur restitue, par sa masse, son surgissement, son homogénéité, presque sa viscosité, la véritable chaire perceptive du monde ; une vision qui tient à distance la perspective géométrique, photographique, cinématographique fondée sur la transparence et qui repose, comme le signale Merleau-Ponty, sur la « réversibilité des dimensions » (surface-profondeur) et l’entrelacement des choses. C’est cette épaisseur du visible rendu par la couleur que l’économie de l’image numérique nous permet de redécouvrir, moins dans le registre de la « tactilité » de l’image et la picturalité du pixel, que par l’intégration, entre le support et l’image (parfois indiscernables dans le régime optique), d’un « corps » algorithmique qui règle l’actualisation du visible. Certains défauts techniques du dispositif numérique, aujourd’hui élevés au rang de pratique artistique, permettent de révéler cette matrice qui utilise alors la couleur et la coulure comme mode de visibilité. C’est le cas du Datamoshing, technique de composition numérique qui revisite tout en la radicalisant la pratique de l’incrustation vidéo. Basée sur la perturbation volontaire d’éléments de la matrice, cette technique transforme les couleurs en une forme malléable et fluide révélant ainsi leur double nature spatiale : elles sont à la fois dans l’espace de l’image et l’espace de l’image lui-même. Ces expériences de défigurations d’images s’inscrivent dans le registre des « aberrations chromatiques » dont nous proposons ici une rapide généalogie avant d’interroger la couleur digitale dans ses spécificités.

Helioseismology and asteroseismology of red giant stars have shown that the distribution of angular momentum in stellar interiors, and its evolution with time remains an open issue in stellar physics. Owing to the unprecedented quality of Kepler photometry, we are able to seismically infer internal rotation rates in γDoradus stars, which provide the MS counterpart to the red-giants puzzle. We confront these internal rotation rates to stellar evolution models with rotationally induced transport of angular momentum, in order to test angular momentum transport mechanisms. We used a stellar model-independent method developed by Christophe et al. in order to obtain seismically inferred, buoyancy radii and near-core rotation for 37 γ Doradus stars observed by Kepler. We show that the buoyancy radius can be used as a reliable evolution indicator for field stars on the MS. We computed rotating evolutionary models including transport of angular momentum in radiative zones, following Zahn and Maeder, with the CESTAM code. This code calculates the rotational history of stars from the birth line to the tip of the RGB. The initial angular momentum content has to be set initially, which is done by fitting rotation periods in young stellar clusters. We show a clear disagreement between the near-core rotation rates measured in the sample and the rotation rates obtained from evolutionary models including rotationally induced transport following Zahn (1992). These results show a disagreement similar to that of the Sun and red giant stars. This suggests the existence of missing mechanisms responsible for the braking of the core before and along the MS. The efficiency of the missing mechanisms is investigated. The transport of angular momentum as formalized by Zahn and Maeder cannot explain the measurements of near-core rotation in main-sequence intermediate-mass stars we have at hand. [less ▲]

Confirming Burnet’s early hypothesis, elimination of self-reactive T cells in the thymus was demonstrated in the late 80’s and an important question immediately arose about the nature of the immune self expressed in the thymus. Many genes encoding neuroendocrine-related and tissue-restricted antigens (TRAs) are transcribed in thymic epithelial cells (TECs). They are then processed for presentation by proteins of the major histocompatibility complex (MHC) expressed by TECs and thymic dendritic cells (DCs). MHC presentation of self-peptides in the thymus programs self-tolerance by two complementary mechanisms: 1° Negative selection of self-reactive ‘forbidden’ T-cell clones starting already in fetal life, and 2° generation of self-specific thymic T regulatory (tTreg) cells, mainly after birth. Many studies, including the discovery of the AutoImmune REgulator (AIRE) and fasciculation and elongation protein zeta family zinc finger (FEZF2) proteins, have shown that a defect in thymus central self-tolerance is the earliest event promoting autoimmunity. AIRE and FEZF2 control the level of transcription of many neuroendocrine self-peptides and TRAs in thymic epithelium. Furthermore, Aire and Fezf2 mutations are associated with development of autoimmunity in peripheral organs. The discovery of the intrathymic presentation of self-peptides has revolutionized our knowledge of immunology and is opening novel avenues for prevention/treatment of autoimmunity. [less ▲]

Cette taxe vise tant les personnes physiques que les entités soumises à l’impôt des personnes morales (I.P.M.) , et donc notamment les A.S.B.L. qui sont soumises à cet impôt . Dans cette contribution, nous proposons un aperçu général des éléments caractéristiques de ce dispositif fiscal pour les assujettis à l’I.P.M., à savoir les différentes définitions des notions-clés (A.), le principe même de la transparence fiscale (B.), l’application différenciée selon la catégorie d’assujettis à laquelle le contribuable appartient (C.), les exceptions à l’application du régime (D.). Pour que l’I.P.M. – et partant la taxe Caïman – puisse être appliqué, l’assujetti devait en principe posséder la personnalité juridique.

Common clay deposits from five localities in Foumban (West Cameroon) were investigated for their morphological, mineralogical and geochemical properties to determine their potential source rocks and suitability in ceramic product. The analytical results were obtained by X-ray diffraction, X-ray fluorescence spectrometry, Thermogravimetric Analysis, Scanning Electron Microscopy, and Fourier Transform Infrared Spectrometry. Morphologically, an homogeneous clayey layer was found in the upper part of a laterite cover on interfluves, and a clayey heterogeneous hydromorphic material in valleys. They are minerallogically composed of kaolinite (25-84%), illite (0-18%), smectite (0- 31%), and chlorite (0-8 %), associated with quartz (2-44 %), K-feldspars (0-27 %.), plagioclase (0-26%), goethite; (0-9%) with traces of rutile and hematite (≤5 %). The geochemical analysis shows a 115 relative large amount of SiO2 (45-71%), Al2O3 (14-31%), and low Fe2O3 (up to 11 %) suggesting weathering of mainly granitic and rhyolitic parent rocks. Most studied clays could be applied to building ceramic product such as bricks (refractory or not) and tiles. Illite may promote the glassy phase responsible for the densification of the final product. In addition, the relatively high proportion of alkali elements (K2O + Na2O, 6-8%) in some samples from Marom, Koutaba and is responsible for low firing temperature. However the presence of smectite (up to 5 %) limits the application of some Koutaba and Marom clays for ceramic building. The high Fe2O3 contents (> 8 %) in some Bangourain clays implied some pretreatment. [less ▲]

We consider a multi-trip vehicle routing problem with time windows (MTVRPTW), in which each vehicle can perform several trips during its working shift. This problem is especially relevant in the context of city logistics. Heuristic solution methods for multi-trip vehicle routing problems often separate routing and assignment phases in order to create trips and then assign them to the available vehicles. We show that this approach is outperformed by an integrated solution method in the presence of time windows. We use an automatic configuration tool to obtain efficient and contextualized implementations of our solution methods. We provide suitable instances for the MTVRPTW as well as an instance generator. Also, we discuss the relevance of two objective functions: the total duration and the total travel time. When minimizing the travel time, large increases of waiting time are incurred, which is not realistic in practice. [less ▲]

Uncountable health care organizations, clinicians, and individuals are striving to prevent obesity and the many chronic medical conditions linked to it by advocating a healthy lifestyle that includes measures such as reducing dietary calorie intake (i.e., calorie restriction = CR and intermittent fasting = IF) or limiting/abolishing animal source foods (i.e., practices termed vegetarianism and veganism). Although these regimens are traditionally considered healthy, their real impact on bone health has yet to be established, and some studies have reported that they have negative effects on bone outcomes. The current work provides an overview of the studies carried out to examine the effect/s of CR, IF and vegetarian/vegan diets on bone health, and, in particular, on bone mineral density (BMD) and fracture risk. Although data on this subject are limited to small studies and there is no information specifically referring to fractures, CR, but not IF, seems to reduce BMD but does not seem to affect bone quality. Vegetarian diets (particularly vegan ones) are associated with significantly lower BMD values with respect to omnivorous ones and could, potentially, increase the risk of fractures. Given these considerations, individuals who decide to follow these diets should be aware of the risk of osteoporosis and of bone fractures and should introduce dietary sources of calcium and Vitamin D and/or supplementation. Future studies examining fracture/osteoporosis incidence in selected populations will be able expand our knowledge about the safety of these diets and the risks linked to them. [less ▲]
