Airborne microflora in Quebec dairy farms : lack of effect of bacterial hay preservatives

Pediococcus pentosaceus is a lactic-acid producing bacterium inoculated in hay to prevent hay deterioration. This study sought to verify the effect of this treatment on the barn microenvironment. Air samples were obtained from 19 barns using bacterial hay treatment and from 18 control barns with six-stage Andersen samplers and all-glass impingers. Appropriate culture media were used for the recovery and identification of microorganisms. Endotoxins were measured with chromogenic Limulus amoebocyte lysate assay. Median values (respectively for treated and untreated hay barns) were: 5.28 × 105 and 3.84 × 105 colony-forming units (CFU)/m3 for total bacteria; 3.18 × 106 and 4.5 × 106 CFU/m3 for molds; 1.36 × 103 and 1.74 × 103 endotoxin units/m3 for endotoxin levels; and 1.03 × 103 and 3.00 × 103 CFU/m3 for Saccharopolyspora rectivirgula. No viable P. pentosaceus were recovered. The presence of S. rectivirgula, the causative agent for farmer's lung, was not influenced by the hay treatment. Since no significant difference was observed in any of the airborne contaminants, this type of hay treatment probably does not protect farmers from the respiratory effect of ambient microbial contaminants

Bueil – Le Pelleret, rue du Puits

Dans le cadre de travaux de pose d’une nouvelle conduite d’assainissement entre Bueil et le hameau de Chanu (commune de Villiers-en-Desœuvre), l’entreprise EHTP a fait la découverte de trois sépultures. Suite à un arrêt de chantier, une opération de fouille urgente consécutive à cette découverte fortuite a pu être engagée. Seine-Normandie-Agglomération, maître d’ouvrage des travaux, a accepté de prendre en charge le financement de l’intervention. Des sondages ponctuels ont été réalisés sur le..

L’activité décisionnelle en phase de contre-attaque en Hockey sur glace

L’objectif de cette étude était de comprendre et de décrire les processus sous-jacents à l’activité décisionnelle dans des situations dynamiques, c’est-à-dire incertaines, évolutives, et imposant une forte pression temporelle. Notre travail a consisté à analyser l’activité de joueurs de hockey-sur-glace en phase naturelle de contre-attaque. Des données comportementales sont enregistrées auprès de six joueurs experts en hockey-sur-glace, puis complétées par des données verbales recueillies lors d’un entretien d’autoconfrontation. Six contre-attaques ont été étudiées. Les données ont été analysées en 5 étapes : a) la retranscription des données, b) la sélection et l’identification des unités significatives, c) le découpage du déroulement de l’activité en situations vécues, d) l’identification des situations et des schémas, et e) la validité de l’analyse. L’analyse du contenu des données obtenues permet d’identifier 10 schémas activés par les joueurs experts en situation de forte pression temporelle. Ces schémas constituent des structures d’arrière-plans articulant des composantes perceptives et cognitives, et qui facilitent la reconnaissance rapide de situations pendant la contre-attaque. Les résultats de cette étude éclairent en partie la complexité de l’activité décisionnelle en situation dynamique et sont discutés au regard d’autres études sur la prise de décision en situation naturelle dans le domaine du sport et de l’ergonomie cognitive.The aim of this study was to understand and describe the underlying processes of decision-making in a dynamic situation, i.e. one that was uncertain, gradual and subject to intense time pressure. Our work involved analysing ice hockey players’ activity in a natural situation of counter-attacking. Behavioural data was recorded from six high-level ice hockey players, supplemented by verbal data collected during self-confrontational interviews. Six counter-attacks were studied. The data were analysed in five stages: (1) generating counter-attack logs, (2) selecting and identifying the elementary units of meaning, (3) analysing the courses of action by dividing up the situations, (4) identifying situations and schemata, and (5) checking the validity of the analysis. An analysis of the data content identified ten schemata used by expert ice hockey players in situations with strict time constraints. These represent the underlying structures which link perceptive and cognitive elements and facilitate the recognition of situations during a counter-attack. The results of this study provide empirical support for the complexity of decision-making in dynamic situations and are discussed with regard to the literature on decision-making in natural situations in the field of sport and cognitive ergonomics

Patterns of Bone Failure in Localized Prostate Cancer Previously Irradiated: The Preventive Role of External Radiotherapy on Pelvic Bone Metastases

Introduction: External beam radiation therapy (EBRT) can cure localized prostate cancer (PCa) by sterilizing cancer cells in the prostate gland and surrounding tissues at risk of microscopic dissemination. We hypothesized that pelvic EBRT for localized PCa might have an unexpected prophylactic impact on the occurrence of pelvic bone metastases.Material and Methods: We reviewed the data of 332 metastatic PCa patients. We examined associations between the number (≤5 vs. >5) and the location of bone metastases (in-field vs. out-of-field), which occurred at first relapse, and a previous history of EBRT for PCa (EBRT vs. No-EBRT).Results: One hundred and ten patients M0 at baseline were eligible. Fifty-six patients (51%) were in the No-EBRT group, and 54 patients (49%) in the EBRT group. The proportion of patients who developed >5 bone metastases in the bony pelvis was higher in the No-EBRT group vs. the EBRT group: 10 patients (18%) vs. 2 patients (4%), respectively (p = 0.02). By multivariate analysis EBRT was associated with a lesser occurrence of patients who had >5 bone metastases in the bony pelvis (OR = 0.17 [95%CI, 0.04–0.87], p = 0.03). Time to occurrence of bone metastases ≥5 years (OR = 0.10 [95%CI, 0.05–0.19], p < 0.01), prior curative prostate treatment (OR = 0.58 [95%CI, 0.36–0.91], p = 0.02), >5 bone metastases in bony pelvis (OR = 2.61 [95%CI, 1.28–5.31], p < 0.01), >5 bone metastases out of bony pelvis (OR = 1.73 [95%CI, 1.09–2.76], p = 0.02) were all predictive of overall survival.Conclusion: Previous pelvic EBRT for PCa is associated with a lower number of pelvic bone metastases, which is associated with better overall survival

Chronic disease patients’ experience with telehealth interventions and self-care strategies during the first wave of the COVID-19 pandemic

Purpose. During COVID-19 pandemic, Québec (Canada) Public Health Agency asked Family Medicine Group (FMG) to change their practice such as recommending the use of telehealth interventions. However, it is unknown if telehealth meets patients' needs in terms of self-care, especially those suffered from physical and mental chronic condition (PCDs). This study aimed to explore, from a PCD's perspective, the response of FMG about their self-care needs during COVID-19 pandemic. Methods. We conducted an exploratory qualitative descriptive study using semi-structured interviews to reach 40 PCDs from three regions of Québec. We explored FMGs' responses, PCDs needs, coping strategies regarding the COVID-19 and the changes in primary care services. We used the transactional theory of stress and coping to inform the data collection and analysis and the COREQ appraisal grid to report this study. Results. PCDs appreciated telehealth and perceived that the accessibility was increased. Moreover, family physicians from FMG conducted the majority of the follow-ups although interdisciplinary teams were available. The coping strategies raised by the PCDs were primarily aimed at maintaining their health status, while some of them aimed to reduce stress levels. Conclusions. PCDs seem to appreciate telehealth but believe it requires improvements, and it is not adequate for all types of follow-ups. PCDs adopt coping strategies to face the pandemic that were not always optimal for their health. We call for a better understanding of PCDs' needs in times of a pandemic in order to offer them the appropriate services an interdisciplinary team can provide.http://deepblue.lib.umich.edu/bitstream/2027.42/167663/1/Article patients-covid copingVF_PP.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/167663/3/Article patients-covid coping VF_V2.pdfDescription of Article patients-covid copingVF_PP.pdf : Main ArticleSEL

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente

Search for chargino-neutralino production with mass splittings near the electroweak scale in three-lepton final states in √s=13 TeV pp collisions with the ATLAS detector

A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of √s=13  TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 139  fb−1. A search, emulating the recursive jigsaw reconstruction technique with easily reproducible laboratory-frame variables, is performed. The two excesses observed in the 2015–2016 data recursive jigsaw analysis in the low-mass three-lepton phase space are reproduced. Results with the full data set are in agreement with the Standard Model expectations. They are interpreted to set exclusion limits at the 95% confidence level on simplified models of chargino-neutralino pair production for masses up to 345 GeV

Search for direct stau production in events with two hadronic tau-leptons in root s=13 TeV pp collisions with the ATLAS detector

A search for the direct production of the supersymmetric partners ofτ-leptons (staus) in final stateswith two hadronically decayingτ-leptons is presented. The analysis uses a dataset of pp collisions corresponding to an integrated luminosity of139fb−1, recorded with the ATLAS detector at the LargeHadron Collider at a center-of-mass energy of 13 TeV. No significant deviation from the expected StandardModel background is observed. Limits are derived in scenarios of direct production of stau pairs with eachstau decaying into the stable lightest neutralino and oneτ-lepton in simplified models where the two staumass eigenstates are degenerate. Stau masses from 120 GeV to 390 GeV are excluded at 95% confidencelevel for a massless lightest neutralino
