[COVID-19, innovating in student mental health].

In this period of health crisis, while students are facing stressful information, a "COVID" nurse demystifies the virus, while a Moroccan nurse promotes the cultural diversity of Arabic and French-speaking prevention messages. Other associative or cultural actions are set up; so many cultural development spaces or solidarity partnerships to help students to get out of their isolation and prevent the appearance of anxiety disorders.

[Students, responsible for their own health].

Like everyone else, students have the ability to adapt. They are socially creative and can become involved in promoting health and their rights. As mediators for their peers, they cultivate solidarity and help strengthen social ties.

[Paramedical students mobilized].

Health students mobilized during the first two epidemic waves of COVID-19. They demonstrated their capacity for autonomy and initiative. They were able to adapt to the reorganization of their training and maintain a strong professional identity.

[COVID-19, student aid, public health and solicitude].

Student aid policies are broad organizational lines. They must not be confused, despite the obvious solicitude of public actors, with the caregiver's posture. It is then necessary to reinterrogate solicitude to defend a form of prevention by the mobilization of the actors, namely the students themselves.

[Urban caregivers helping students].

In this period of pandemic, urban caregivers are directly concerned by the mental or social distress of students. In addition to university health services, psychologists through associations, social workers, doctors and nurses are listening to young people for individual situations, but sometimes also for group situations. So many access to health to propose to the suffering students as well as to their families.

[The university health service: Role of a mental health nurse].

University health services have been serving students for many years. During this very particular health crisis, they are actively caring for the health of their population, including psychological health. Nursing skills are essential here.

[The balance of healthcare students in jeopardy].

Healthcare students have experienced this first year of the COVID-19 pandemic differently. Some have volunteered to support services in tension. They were concerned about whether their training would be provided, especially for technical skills.

[Impact of the pandemic on students].

French society has become aware of the distress of students, to the point of setting up systems dedicated to their mental health. To avoid confusion, it is important to qualify the mental health of students and to suggest ways to understand why this is a vulnerable population facing the health crisis.

Spin occurs in bariatric surgery randomized controlled trials with a statistically nonsignificant primary outcome: A systematic review.

Objectives: To systematically identify the strategy and frequency of spin in reports of bariatric surgery randomized controlled trials (RCTs) with statistically nonsignificant primary endpoint.

Study Design And Setting: The use of specific reporting strategies to highlight the beneficial effect of an experimental treatment can affect the reader interpretation of trial results, particularly when the primary endpoint is not statistically significant. A literature search was performed to identify RCTs publications assessing the impact of bariatric surgery on obesity-related comorbidities published over the past 10 years (from January 2020 till December 2020) in MEDLINE and EMBASE.

Towards improved breast mass detection using dual-view mammogram matching.

Breast cancer screening benefits from the visual analysis of multiple views of routine mammograms. As for clinical practice, computer-aided diagnosis (CAD) systems could be enhanced by integrating multi-view information. In this work, we propose a new multi-tasking framework that combines craniocaudal (CC) and mediolateral-oblique (MLO) mammograms for automatic breast mass detection.

Machine Learning and Natural Language Processing in Mental Health: Systematic Review.

Background: Machine learning systems are part of the field of artificial intelligence that automatically learn models from data to make better decisions. Natural language processing (NLP), by using corpora and learning approaches, provides good performance in statistical tasks, such as text classification or sentiment mining.

Objective: The primary aim of this systematic review was to summarize and characterize, in methodological and technical terms, studies that used machine learning and NLP techniques for mental health.

Transition to turbulence via flame patterns in viscoelastic Taylor-Couette flow.

Transition to inertio-elastic turbulence in Taylor-Couette flow with shear-thinning and viscoelastic polymer solutions is investigated when the rotation rate of the inner cylinder is increased and the outer cylinder is fixed. In two polymer solutions of PEO with elastic number [Formula: see text], the first instability of the circular Couette flow appears as spirals propagating in opposite directions along the axis of cylinders. Just above the onset of the spirals pattern, the localized solitons of the strong radial inflow called flame-like flow appear abruptly inside waves.

Evaluation of the Antioxidant, Anti-Inflammatory and Cytoprotective Activities of Halophyte Extracts against Mycotoxin Intoxication.

Twelve halophyte species belonging to different families, widely represented along French Atlantic shoreline and commonly used in traditional medicine, were screened for protective activities against mycotoxins, in order to set out new promising sources of natural ingredients for feed applications. Selected halophytic species from diverse natural habitats were examined for their in vitro anti-mycotoxin activities, through viability evaluation of Madin-Darby Bovine Kidney (MDBK) and intestinal porcine enterocyte (IPEC-J2) cell lines. Besides, the in vitro antioxidant activities of plant extracts were assessed (total antioxidant and 2,2-diphenyl-1-picrylhydrazyl (DPPH)-scavenging bioassays).

[Consent in mental health, between semiotic object and figure of psychiatric care].

Working on the question of consent in psychiatry means studying closely the word given by a patient, who, before being mentally ill, is a person with a real human value. It is a question of eliciting consent, of seeking it tirelessly rather than demanding it, so that it never becomes a procedure imposed by the fact of setting a purely formal condition, at the risk of otherwise abandoning it to the power of the psychiatric doctor. This is all the more important as the criterion of free care, including today both free hospitalization and freely deployed outpatient care, remains as an essential benchmark of the therapeutic alliance, the consent of the patient.

Spin Crossover and High-Spin State in Fe(II) Anionic Polymorphs Based on Tripodal Ligands.

Two new mononuclear Fe(II) polymorphs, [(CH)N][Fe(pyC-OEt)(NCS)] () and [(CH)N][Fe(pyC-OEt)(NCS)] () (pyC-OEt = tris(pyridin-2-yl)ethoxymethane), have been synthesized and characterized by single-crystal X-ray diffraction, by magnetic and photomagnetic measurements, and by detailed variable-temperature infrared spectroscopy. The molecular structure, in both complexes, is composed of the same anionic [Fe(pyC-OEt)(NCS)] complex (two units for and one unit for ) generated by coordination to the Fe(II) metal center of one tridentate pyC-OEt tripodal ligand and three terminal κ-SCN coligands. Magnetic studies revealed that polymorph displays a high-spin (HS) state over the entire studied temperature range (300-10 K), while complex exhibits an abrupt and complete spin crossover (SCO) transition at ca.

Influence of QD photosensitizers in the photocatalytic production of hydrogen with biomimetic [FeFe]-hydrogenase. Comparative performance of CdSe and CdTe.

Photocatalytic systems comprising a hydrogenase-type catalyst and CdX (X = S, Se, Te) chalcogenide quantum dot (QD) photosensitizers show extraordinary hydrogen production rates under visible light excitation. What remains unknown is the mechanism of energy conversion in these systems. Here, we have explored this question by comparing the performance of two QD sensitizers, CdSe and CdTe, in photocatalytic systems featuring aqueous suspensions of a [Fe (μ-1,2-benzenedithiolate) CO] catalyst and an ascorbic acid sacrificial agent.

Cold-spray ionization mass spectrometry of the choline chloride-urea deep eutectic solvent (reline).

Cold-Spray Ionization mass spectrometry (CSI-MS) that can be compared to an electrospray ionization (ESI) source acting with a nebulizing gas cooled by liquid nitrogen is used for analyzing reline as Deep Eutectic Solvent (DES). The association of cholinium chloride salts with urea molecules is evidenced in negative CSI-MS through the chloride adduct formation. The structure of the supramolecular assemblies forming the reline ions that are observed on CSI mass spectra is rationalized by chemical quantum calculations.

An elevated polyclonal free light chain level reflects a strong interferon signature in patients with systemic autoimmune diseases.

High amount of polyclonal free light chains (FLC) are reported in systemic autoimmune diseases (SAD) and we took advantage of the PRECISESADS study to better characterize them. Serum FLC levels were explored in 1979 patients with SAD (RA, SLE, SjS, Scl, APS, UCTD, MCTD) and 614 healthy controls. Information regarding clinical parameters, disease activity, medications, autoantibodies (Ab) and the interferon α and/or γ scores were recorded.

Relative Efficiency of Pitfall vs. Bait Trapping for Capturing Taxonomic and Functional Diversities of Ant Assemblages in Temperate Heathlands.

Whereas bait and pitfall trappings are two of the most commonly used techniques for sampling ant assemblages, they have not been properly compared in temperate open habitats. In this study, taking advantage of a large-scale project of heathland restoration (three sites along the French Atlantic Coast forming a north-south gradient), we evaluated the relative efficiency of these two methods for assessing both taxonomic and functional diversities of ants. Ants were collected and identified to species level, and six traits related to morphology, behavior (diet, dispersal and maximum foraging distance), and social life (colony size and dominance type) were attributed to all 23 species.

Spectrum Sensing for Cognitive Radio: Recent Advances and Future Challenge.

Spectrum Sensing (SS) plays an essential role in Cognitive Radio (CR) networks to diagnose the availability of frequency resources. In this paper, we aim to provide an in-depth survey on the most recent advances in SS for CR. We start by explaining the Half-Duplex and Full-Duplex paradigms, while focusing on the operating modes in the Full-Duplex.

It is, in particular, used by researchers and industrials to design, optimize, understand and create innovative emission tomography systems. In this paper, we reviewed the recent developments that have been proposed to simulate modern detectors and provide a comprehensive report on imaging systems that have been simulated and evaluated in GATE.

Reduction of RUNX1 transcription factor activity by a CBFA2T3-mimicking peptide: application to B cell precursor acute lymphoblastic leukemia.

Background: B Cell Precursor Acute Lymphoblastic Leukemia (BCP-ALL) is the most common pediatric cancer. Identifying key players involved in proliferation of BCP-ALL cells is crucial to propose new therapeutic targets. Runt Related Transcription Factor 1 (RUNX1) and Core-Binding Factor Runt Domain Alpha Subunit 2 Translocated To 3 (CBFA2T3, ETO2, MTG16) are master regulators of hematopoiesis and are implicated in leukemia.

[Management of patients with a suspicion of giant cell arteritis: Survey among general practitioners and specialists].

Introduction: Headache, visual disturbances and shoulder and hip girdle pain are frequent symptoms of consultation and the diagnosis of giant cell arteritis (GCA) can be evoked in these situations. However, GCA is a rare disease, and the management modalities of a clinical suspicion of GCA are poorly described, which warranted this study.

Methods: This is a survey evaluating the management of a suspected case of GCA.

Thio-ether functionalized glycolipid amphiphilic compounds reveal a potent activator of SK3 channel with vasorelaxation effect.

The modulation of SK3 ion channels can be efficiently and selectively achieved by using the amphiphilic compound Ohmline (a glyco-glycero-ether-lipid). We report herein a series of Ohmline analogues featuring the replacement of one ether function by a thioether function located at the same position or shifted close to its initial position. The variation of the lipid chain length and the preparation of two analogues featuring either one sulfoxide or one sulfone moiety complete this series.
