Résumé : BACKGROUND: Concussions are a source of major concern in rugby, and a limited number of studies have attempted to identify risk factors for these injuries. PURPOSE: To investigate the incidence of match concussion and associated risk factors, including individual workload, anthropometric variables, playing position, and season phase, in elite rugby union players. STUDY DESIGN: Case-control study; Level of evidence 3. METHODS: All concussions and explanatory variables were collected for every match over 5 consecutive seasons (2014-2018) in 1334 professional players participating in the French Top 14 championship. Concussion risk was estimated using mixed effects Poisson regression. RESULTS: Mean match concussion incidence equated to 10.4 (95% CI, 9.3-11.5) concussions for 1000 hours of game exposure. A peak was reached in the 2016-2017 season (13.7; 95% CI, 11.0-16.5). A greater risk was observed in the playoffs as compared with the first phase of the season (incidence rate ratio, 3.96; 95% CI, 2.10-7.35). In comparison with other positions, half-backs incurred the highest rate of concussion events (incidence, 16.1; 95% CI, 11.8-20.3). Irrespective of playing position, those with greater height and lower body mass reported a higher risk of concussions (P = .02), especially during tackling actions for lighter players (P = .01) and during other match events for taller players (P = .03). When adjusted for season phase, players who had accumulated a higher amount of playing time since the beginning of the season demonstrated a lower risk of concussion (P = .005). CONCLUSION: Inter- and intraseasonal variations in concussion rates were observed. Within positional groups, lighter and taller players were more at risk, with the highest incidence generally observed in half-backs. Workload was measured by the number of matches played before a concussion event, and it appeared to have a protective rather than deleterious effect on concussion risk.

Résumé : The MALINA oceanographic campaign was conducted during summer 2009 to investigate the carbon stocks and the processes controlling the carbon fluxes in the Mackenzie River estuary and the Beaufort Sea. Dur- ing the campaign, an extensive suite of physical, chemical and biological variables was measured across seven shelf–basin transects (south-north) to capture the meridional gradient between the estuary and the open ocean.Key variables such as temperature, absolute salinity, radiance, irradiance, nutrient concentrations, chlorophyll-a concentration, bacteria, phytoplankton and zooplankton abundance and taxonomy, and carbon stocks and fluxes were routinely measured onboard the Canadian research icebreaker CCGS Amundsen and from a barge in shallow coastal areas or for sampling within broken ice fields. Here, we present the results of a joint effort to tidy and standardize the collected data sets that will facilitate their reuse in further studies of the changing Arctic Ocean.

Résumé : Objectives To determine whether the familial clustering of amyotrophic lateral sclerosis (ALS) cases and the phenotype of the disease may help identify the pathogenic genes involved. Methods We conducted a targeted next-generation sequencing analysis on 235 French familial ALS (FALS), unrelated probands to identify mutations in 30 genes linked to the disease. The genealogy, that is, number of cases and generations with ALS, gender, age, site of onset and the duration of the disease were analysed. Results Regarding the number of generations, 49 pedigrees had only one affected generation, 152 had two affected generations and 34 had at least three affected generations. Among the 149 pedigrees (63.4%) for which a deleterious variant was found, an abnormal G4C2 expansion in C9orf72 was found in 98 cases as well as SOD1 , TARBP or FUS mutations in 30, 9 and 7 cases, respectively. Considering pedigrees from the number of generations, abnormal G4C2 expansion in C9orf72 was more frequent in pedigrees with pairs of affected ALS cases, which represented 65.2% of our cohort. SOD1 mutation involved all types of pedigrees. No TARDBP nor FUS mutation was present in monogenerational pedigrees. TARDBP mutation predominated in bigenerational pedigrees with at least three cases and FUS mutation in multigenerational pedigrees with more than seven cases, on average, and with an age of onset younger than 45 years. Conclusion Our results suggest that familial clustering, phenotypes and genotypes are interconnected in FALS, and thus it might be possible to target the genetic screening from the familial architecture and the phenotype of ALS cases.

Résumé : The European Commission mandated EFSA to complement its original scientific opinion on soybean MON 87769 3 MON 89788 (EFSA-GMO-NL-2010-85) considering additional information on the human nutritional assessment of refined bleached deodorised oil produced from the two-event stack soybean (RBD GM-oil). The assessment was mainly based on a replacement scenario with a list of target foods where RBD GM-oil is intended to be added. Intake estimations for several fatty acids present in the RBD GM-oil, in particular c-linolenic acid (GLA), stearidonic acid (SDA) and linoleic acid (LA) were based on the consumption of the corresponding foods that are likely to be displaced. The assessment of LA considered the established adequate intake of 4% of total energy intake (E%) and that LA deficiency has not been observed with intakes > 1 E%. The assessment of GLA and SDA was conducted using maximum doses without adverse effects from intervention human studies as reference (4.2 grams/day for SDA and 2.8 grams/day for GLA) since no tolerable upper intake levels are set for these fatty acids. The decrease observed in the levels of LA in RBD GM-oil as compared to oil from conventional soybean does not represent a nutritional concern as intakes were in all cases above 1 E%. For GLA, all intake estimations were below the reference dose indicating no safety concern. SDA intake estimations do not pose any safety concerns based on the overly conservative nature of the estimates, the absence of toxicological hazards and the rapid metabolism of SDA in humans. The GMO Panel concluded that the consumption of soybean MON 87769 3 MON 89788 and their derived products, in particular its RBD oil, does not represent a nutritional concern in humans. A post-market monitoring plan is recommended to confirm the predicted consumption and the application of conditions of uses considered during the pre-market risk assessment.

Résumé : The nonreceptor tyrosine kinase FAK is a promising target for solid tumor treatment because it promotes invasion, tumor progression, and drug resistance when overexpressed. In-vestigating the role of FAK in human melanoma cells, we found that both in situ and metastatic melanoma cells strongly express FAK, where it controls tumor cells’ invasiveness by regulating focal adhesion-mediated cell motility. Inhibiting FAK in human metastatic melanoma cells with either siRNA or a small inhibitor targeting the kinase domain impaired migration but led to increased invadopodia formation and extracellular matrix degradation. Using FAK mutated at Y397, we found that this unexpected increase in invadopodia activity is due to the lack of phosphorylation at this residue. To preserve FAK–Src interaction while inhibiting pro-migratory functions of FAK, we found that altering FAK–paxillin interaction, with either FAK mutation in the focal adhesion targeting (FAT) domain or a competitive inhibitor peptide mimicking paxillin LD domains drastically reduces cell migration and matrix degradation by preserving FAK activity in the cytoplasm. In conclusion, our data show that targeting FAK–paxillin interactions could be a potential therapeutic strategy to prevent metastasis formation, and molecules targeting this interface could be alternative to inhibitors of FAK kinase activity which display unexpected effects.

Résumé : La punaise Brachyplatys subaeneus est un ravageur mineur des Fabaceae originaire d’Asie tropicale et subtropicale humide qui a déjà été signalé dans d’autres pays comme le Panama (2012), la République Dominicaine et le Costa Rica (2019). La punaise a été détectée en Guadeloupe en août 2020 sur pois d’Angole (Cajanus cajan – Fabaceae) dans un jardin de particulier sur la commune de Petit-Bourg. Cet organisme nuisible (ON) est potentiellement polyphage. On suppose que Brachyplatys subaeneus a la capacité de se déplacer via les flux commerciaux. En effet, une autre espèce de punaise de la même famille des Plataspidae (Megacopta cribaria) a été interceptée lors de transports de marchandises sans lien avec les filières végétales concernées. Les Antilles et la Guyane ont de nombreux échanges commerciaux avec des pays où Brachyplatys subaeneus est déjà présente tels que la Chine ou la République Dominicaine. L’Anses est saisie afin d’apporter son avis sur les points suivants : - Quelle est la probabilité d’introduction de Brachyplatys subaeneus en Martinique et Guyane via les importations en provenance de pays tiers à risque ou de flux inter-DOM ? Sur quels types de flux (végétaux, palettes en bois, autres marchandises) ? - Est-ce que cet ON présente une nuisibilité (impacts économiques, environnementaux ou sociaux) en Martinique et Guyane ? - Si Brachyplatys subaeneus présente les caractéristiques d’un organisme de quarantaine avec un risque phytosanitaire inacceptable, quelles sont les mesures de gestion appropriées (aux frontières ou à l’intérieur de la zone) vis-à-vis de cette punaise ?

Résumé : UltraViolet & infrared Sensors at high Quantum efficiency onboard a small SATellite (UVSQ- SAT) is a small satellite at the CubeSat standard, whose development began as one of the missions in the International Satellite Program in Research and Education (INSPIRE) consortium in 2017. UVSQ- SAT is an educational, technological and scientific pathfinder CubeSat mission dedicated to the observation of the Earth and the Sun. It was imagined, designed, produced and tested by LATMOS in collaboration with its academic and industrial partners, and the French-speaking radioamateur community. About the size of a Rubik’s Cube and weighing about 2 kg, this satellite was put in orbit in January 2021 by the SpaceX Falcon 9 launch vehicle. After briefly introducing the UVSQ-SAT mission, this paper will present the importance of measuring the Earth’s radiation budget and its energy imbalance and the scientific objectives related to its various components. Finally, the first in-orbit observations will be shown (maps of the solar radiation reflected by the Earth and of the outgoing longwave radiation at the top of the atmosphere during February 2021). UVSQ-SAT is one of the few CubeSats worldwide with a scientific goal related to climate studies. It represents a research in remote sensing technologies for Climate observation and monitoring.

Résumé : The rate of mother-to-child transmission (MTCT) of HIV from breastfeeding is increasing relative to other causes of MTCT. Early effective preconception and antenatal antiretroviral therapy (ART) reduces intrauterine and intrapartum MTCT, whereas maternal post-partum HIV acquisition, untreated maternal HIV, and suboptimal postnatal maternal ART adherence increase the risk of MTCT through breastfeeding. Although the absolute number of cases of MTCT acquired through breastfeeding is decreasing, the rate of decrease is less than the decrease in intrauterine and intrapartum MTCT. Unless current strategies are universally applied, they might not be sufficient to eliminate MTCT due to breastfeeding. Urgent action is needed to evaluate and implement additional preventive biomedical strategies in high HIV prevalence and incidence settings to eliminate MTCT from breastfeeding. Preventive strategies include: pre-exposure prophylaxis in breastfeeding women who have an increased risk of acquiring HIV; postnatal reinforcement strategies, such as maternal retesting for HIV, maternal care reinforcement, and prophylaxis in infants exposed to HIV via breastmilk; and active (vaccine) or passive immunoprophylaxis with long-acting broadly neutralising antibodies.
