Value of a secretomic approach for distinguishing patients with COVID-19 viral pneumonia among patients with respiratory distress admitted to intensive care unit.

In intensive care units, COVID-19 viral pneumonia patients (VPP) present symptoms similar to those of other patients with Nonviral infection (NV-ICU). To better manage VPP, it is therefore interesting to better understand the molecular pathophysiology of viral pneumonia and to search for biomarkers that may clarify the diagnosis. The secretome being a set of proteins secreted by cells in response to stimuli represents an opportunity to discover new biomarkers.

O-GlcNAcylation levels remain stable regardless of the anaesthesia in healthy rats.

Anaesthetics are used daily in human and veterinary medicine as well as in scientific research. Anaesthetics have an impact on cell homeostasis especially through modulation of protein post-translational modifications. O-GlcNAcylation, a ubiquitous post-translational modification, plays a role in many biological processes.

Use of FeNO to predict anti-IL-5 and IL-5R biologics efficacy in a real-world cohort of adults with severe eosinophilic asthma.

Introduction: Severe eosinophilic asthma (SEA) is associated with multiple exacerbations. Fractional exhaled nitric oxide (FeNO), a biomarker of airway T2 inflammation, is known to be correlated with the risk of exacerbations. While the use of FeNO is well established to predict the therapeutic response to dupilumab (anti-IL-4/IL-13), it remains uncertain for biologics targeting the IL-5 pathway.

Bronchial smooth muscle cell in asthma: where does it fit?

Asthma is a frequent respiratory condition whose pathophysiology relies on altered interactions between bronchial epithelium, smooth muscle cells (SMC) and immune responses. Those leads to classical hallmarks of asthma: airway hyper-responsiveness, bronchial remodelling and chronic inflammation. Airway smooth muscle biology and pathophysiological implication in asthma are now better understood.

[A new pathophysiological element in severe asthma: GTPase Rac].

Asthma is a chronic airway condition defined by hyperresponsiveness, bronchial remodeling and chronic inflammation. A significant proportion of severe asthmatic patients remain uncontrolled despite recent therapeutic breakthroughs (biotherapies). Better understanding of the signaling pathways involved in the pathophysiological mechanisms underlying severe asthma could successfully address this unmet need.

Type 2 immunity-driven diseases: Towards a multidisciplinary approach.

Asthma, atopic dermatitis and chronic rhinoconjunctivitis are highly heterogeneous. However, epidemiologic associations exist between phenotypic groups of patients. Atopic march is one such association but is not the only common point.

Why women choose at-home abortion via teleconsultation in France: drivers of telemedicine abortion during and beyond the COVID-19 pandemic.

Objectives: In an attempt to understand the demand and main drivers of telemedicine abortion, we analysed the requests that Women on Web (WoW), an online telemedicine abortion service operating worldwide, received from France throughout 2020.

Methods: We conducted a parallel, convergent, mixed-methods study among 809 consultations received from France at WoW between 1 January and 31 December 2020. We performed a cross-sectional study of data obtained from the WoW consultation survey and a manifest content analysis of anonymised email correspondence of 140 women consulting with the WoW helpdesk from France.

Essential role of smooth muscle Rac1 in severe asthma-associated airway remodelling.

Background: Severe asthma is a chronic lung disease characterised by inflammation, airway hyperresponsiveness (AHR) and airway remodelling. The molecular mechanisms underlying uncontrolled airway smooth muscle cell (aSMC) proliferation involved in pulmonary remodelling are still largely unknown. Small G proteins of the Rho family (RhoA, Rac1 and Cdc42) are key regulators of smooth muscle functions and we recently demonstrated that Rac1 is activated in aSMC from allergic mice.

Needs for Systems Approaches to Better Treat Individuals With Severe Asthma: Predicting Phenotypes and Responses to Treatments.

Asthma is a frequent heterogeneous multifactorial chronic disease whose severe forms remain largely uncontrolled despite the availability of many drugs and educational therapy. Several phenotypes and endotypes of severe asthma have been described over the last two decades. Typical type-2-immunity-driven asthma remains the most frequent phenotype, and several targeted therapies have been developed and are now available.

The IL-15 / sIL-15Rα complex modulates immunity without effect on asthma features in mouse.

Background: Interleukin 15 (IL-15) is a growth and modulating factor for B, T lymphocytes and natural killer cells (NK). Its action on innate and adaptive immunity is modulated by its alpha chain receptor (IL-15Rα). The IL-15/sIL-15Rα complex (IL-15Cx) increases the bioavailability and activity of the cytokine in vivo.

Clinical practice guidelines for contraception by the French National College of Gynecologists and Obstetricians (CNGOF).

The French College of Obstetrics and Gynecology (CNGOF) has released its first comprehensive recommendations for clinical practices in contraception, to provide physicians with an updated synthesis of the available data as a basis for their practice. The organizing committee and the working group adopted the objective methodological principles defined by the French Authority for Health (HAS) and selected 12 themes relevant to medical professionals' clinical practices concerning contraception. The available literature was screened through December 2017 and served as the basis of 12 texts, reviewed by experts and physicians from public and private practices, with experience in this field.

[New protagonists in asthma pathophysiology].

Asthma is often associated with a Th2-type immune response with well-known cellular and molecular actors such as eosinophils, Th2 lymphocytes and associated cytokines such as interleukin-5 or IL-4. Nevertheless, some of the asthmatic patients show clinical manifestations and characteristics that do not correspond to the current pattern of the pathophysiology of asthma. Thus, recently new cellular and molecular actors in the development of asthma have been demonstrated in animal models and in humans.

[Contraception: CNGOF Guidelines for Clinical Practice (Short Version)].

The French College of Obstetrics and Gynecology (CNGOF) releases its first global recommendations for clinical practice in contraception, to provide physicians with an updated synthesis of available data as a basis for their practice. The French Health Authority (HAS) methodology was used. Twelve practical issues were selected by the organizing committee and the task force members.

[Natural Family Planning methods and Barrier: CNGOF Contraception Guidelines].

Objective: To develop clinical practice recommendations for the use of natural contraception and female and male barrier methods.

Materials And Methods: A systematic review of English and French literatures related to the safety and effectiveness of natural contraceptive methods based on PubMed, Cochrane Library, practice recommendations issued by international scientific societies and guidelines provided by the World Health Organization (WHO) as well as updates from the Center for Disease Control and Prevention (CDC).

Results: Natural contraceptives methods include fertility awareness-based methods, lactational amenorrhea method (LAM) and withdrawal method.

Radiological pleuroparenchymal fibroelastosis associated to limited cutaneous systemic sclerosis: a case report.

Background: Pleuroparenchymal fibroelastosis (PPFE) is a very rare interstitial lung disease (ILD) characterized by progressive fibrotic lesions of the visceral pleura and the sub-pleural parenchyma, affecting predominantly the upper lobes. PPFE may occur in different contextes like bone marrow or lung transplantations, but also in the context of telomeropathy with mutations of telomerase reverse transcriptase (TERT), telomerase RNA component (TERC) or regulator of telomere elongation helicase 1 (RTEL1) genes. PPFE-like lesions have recently been described in patients with connective tissue disease (CTD)-related ILD.

Elective abortion: Clinical practice guidelines from the French College of Gynecologists and Obstetricians (CNGOF).

The number of elective abortions has been stable for several decades. Many factors explain women's choice of abortion in cases of unplanned pregnancies. Early initiation of contraceptive use and a choice of contraceptive choices appropriate to the woman's life are associated with lower rates of unplanned pregnancies.

[Medical induced abortion].

Objective: Updated clinical recommendations for medical induced abortion procedure.

Methods: A systematic review of French and English literature, reviewing the evidence relating to the provision of medical induced abortion was carried out on PubMed, Cochrane Library and international scientific societies recommendations.

Results: The effectiveness of medical abortion is higher than 95% when the protocols are adjusted to gestational age (EL1).

[Induced abortion: Guidelines for clinical practice - Text of the Guidelines (short text)].

Objective: Develop recommendations for the practice of induced abortion.

Materials And Methods: The Pubmed database, the Cochrane Library and the recommendations from the French and foreign Gyn-Obs societies or colleges have been consulted.

Results: The number of induced abortions (IA) has been stable for several decades.

Mesenchymal Stem Cells Induce Suppressive Macrophages Through Phagocytosis in a Mouse Model of Asthma.

Mesenchymal stem cell (MSC) immunosuppressive functions make them attractive candidates for anti-inflammatory therapy in allergic asthma. However, the mechanisms by which they ensure therapeutic effects remain to be elucidated. In an acute mouse model of house dust mite (Der f)-induced asthma, one i.

Feasibility of self-performed urine pregnancy testing for follow-up after medical abortion.

Objectives: Medical termination of pregnancy (MToP) follow-up can be simplified by combining a clinical assessment with blood and urine human chorionic gonadotropin (hCG) measurements, the later using a low sensitivity urinary pregnancy (LSUP) testing. This study aimed to describe follow-up modalities of MToP in real-life conditions, and assess the benefit of a self-performed urine semiquantitative test in the follow-up of MToP and its feasibility, acceptability and user-friendliness as well as the women capacity to interpret it correctly. Concordance between qualitative results from LSUP test and quantitative values from the blood hCG measurement was also assessed.
