Optimized husbandry and targeted gene-editing for the cnidarian Nematostella vectensis.

Optimized laboratory conditions for research models are crucial for the success of scientific projects. This includes controlling the entire life cycle, having access to all developmental stages and maintaining stable physiological conditions. Reducing the life cycle of a research model can also enhance the access to biological material and speed up genetic tool development.

Extensive environmental survey of free-living amoebae and their elusive association with Mycobacterium bovis or Mycobacterium avium subsp. paratuberculosis.

Free-living amoebae (FLA) are described as environmental reservoirs for some bacteria able to resist their phagocytosis. In the environment, the fate of Mycobacterium bovis (Mbo) and Mycobacterium avium subsp. paratuberculosis (Map) responsible for bovine tuberculosis and paratuberculosis, respectively, remains poorly understood and is considered potentially problematic in the eradication and control of these diseases.

Effectiveness evaluation of an organisational intervention, targeting pregnancy and addiction care professionals, among women who have just given birth in maternity wards and smoked tobacco during pregnancy (5A-QUIT-N): study protocol for a stepped-wedge cluster randomised trial.

Introduction: In 2021, among French women who smoked when they knew they were pregnant, 59% still smoked at the end of pregnancy. Support for pregnant women to stop smoking must include a structured organisational perspective. The main objective of the study is to evaluate the effectiveness of the 5A-QUIT-N organisational intervention on smoking cessation at delivery among pregnant women who smoke during pregnancy.

Development of a performance-based toolkit of the treatable traits of functioning in hospitalised patients with exacerbation of COPD: a survey-based study protocol.

Background: The management of COPD has been based on the premise of identifying problems that guide personalised treatment based on a multidimensional assessment, known as treatable traits. Exacerbation of COPD (ECOPD) results in physical and functional impairments, limitation of daily activities and negative impact on patients' quality of life and prognosis. In this context, identifying treatable traits in patients with ECOPD is essential to properly guide individualised patient care.

Precision Medicine in Pancreatic Ductal Adenocarcinoma: The Impact of Targeted Therapies on Survival of Patients Harboring Actionable Mutations.

Background: Pancreatic ductal adenocarcinoma (PDAC) is the third leading cause of death by cancer worldwide. Mostly diagnosed with locally advanced or metastatic disease, patients lack treatment options. Gene alterations (GAs) are frequently observed in PDAC, some of which are considered for molecular targeted therapies (MTTs), with potential clinical benefits and improved outcomes.

Patient satisfaction, experience and preferences in the implementation of genetics teleconsultations in the North-eastern region of France.

Introduction: In France, few centres per region offer genetics consultations. Consequently, each centre covers a large area, often requiring patients to take a day off to travel long distances. In certain situations, genetic counselling in particular, a physical exam is not required.

Reference equations for quadriceps strength, endurance and power: a multicentre study.

Introduction: The lack of reference values of lower-limb muscle function hinders the clinical recommendations of its measurement in patients with COPD. Therefore, this study aimed to develop reference equations to predict reference values for quadriceps strength, endurance and power and evaluate their construct validity in patients with COPD.

Methods: Quadriceps strength, endurance and power were assessed in 158 healthy individuals and 87 patients with COPD.

Tumor-derived interleukin-1 receptor antagonist exhibits immunosuppressive functions and promotes pancreatic cancer.

Background: Pancreatic ductal adenocarcinoma (PDA) is a pernicious disease characterized by an immunosuppressive milieu that is unresponsive to current immunotherapies. Interleukin-1 receptor antagonist (IL-1Ra) is a natural anti-inflammatory cytokine; however, its contribution to cancer pathogenesis and immunosuppression remains elusive. In this research, we investigated the role and mechanism of IL-1Ra in malignant progression of PDA.

Occupational exposure to silica dust in France: an ongoing concern.

Objectives: Crystalline silica is found in many construction materials. Although it is one of the oldest known occupational exposures, new exposure contexts have emerged in recent years. In 2021, France classified work involving exposure to respirable crystalline silica (ie, silica dust) generated by a work process as carcinogenic.

Symptoms and quality of life before, during, and after a SARS-CoV-2 PCR positive or negative test: data from Lifelines.

This study evaluates to what extent symptoms are present before, during, and after a positive SARS-CoV-2 polymerase chain reaction (PCR) test, and to evaluate how the symptom burden and quality of Life (QoL) compares to those with a negative PCR test. Participants from the Dutch Lifelines COVID-19 Cohort Study filled-out as of March 2020 weekly, later bi-weekly and monthly, questions about demographics, COVID-19 diagnosis and severity, QoL, and symptoms. The study population included those with one positive or negative PCR test who filled out two questionnaires before and after the test, resulting in 996 SARS-CoV-2 PCR positive and 3978 negative participants.

European Respiratory Society statement on frailty in adults with chronic lung disease.

Frailty is a complex, multidimensional syndrome characterised by a loss of physiological reserves that increases a person's susceptibility to adverse health outcomes. Most knowledge regarding frailty originates from geriatric medicine; however, awareness of its importance as a treatable trait for people with chronic respiratory disease (including asthma, COPD and interstitial lung disease) is emerging. A clearer understanding of frailty and its impact in chronic respiratory disease is a prerequisite to optimise clinical management in the future.

The sexual dimorphism of kidney growth in mice and humans.

Kidney mass and function are sexually determined, but the cellular events and the molecular mechanisms involved in this dimorphism are poorly characterized. By combining female and male mice with castration/replacement experiments, we showed that male mice exhibited kidney overgrowth from five weeks of age. This effect was organ specific, since liver and heart weight were comparable between males and females, regardless of age.

Fatigue in patients with chronic disease: results from the population-based Lifelines Cohort Study.

(1) To evaluate the prevalence of severe and chronic fatigue in subjects with and without chronic disease; (2) to assess to which extent multi-morbidity contributes to severe and chronic fatigue; and (3) to identify predisposing and associated factors for severe and chronic fatigue and whether these are disease-specific, trans-diagnostic, or generic. The Dutch Lifelines cohort was used, including 78,363 subjects with (n = 31,039, 53 ± 12 years, 33% male) and without (n = 47,324, 48 ± 12 years, 46% male) ≥ 1 of 23 chronic diseases. Fatigue was assessed with the Checklist Individual Strength-Fatigue.

Objectively Measured Physical Activity as a COPD Clinical Trial Outcome.

Background: Reduced physical activity is common in COPD and is associated with poor outcomes. Physical activity is therefore a worthy target for intervention in clinical trials; however, trials evaluating physical activity have used heterogeneous methods.

Research Question: What is the available evidence on the efficacy and/or effectiveness of various interventions to enhance objectively measured physical activity in patients with COPD, taking into account the minimal preferred methodologic quality of physical activity assessment?

Study Design And Methods: In this narrative review, the COPD Biomarker Qualification Consortium (CBQC) task force searched three scientific databases for articles that reported the effect of an intervention on objectively measured physical activity in COPD.

Recovery from COVID-19: a sprint or marathon? 6-month follow-up data from online long COVID-19 support group members.

Background: It remains unknown whether and to what extent members of online "long COVID" peer support groups remain symptomatic and limited over time. Therefore, we aimed to evaluate symptoms in members of online long COVID peer support groups up to 6 months after the onset of coronavirus disease 2019 (COVID-19)-related symptoms.

Methods: Demographics, symptoms, health status, work productivity, functional status and health-related quality of life were assessed about 3 and 6 months after the onset of COVID-19-related symptoms in members of online long COVID peer support groups.

The prevalence and related factors of fatigue in patients with COPD: a systematic review.

Background: Fatigue is a distressing symptom in patients with COPD. Little is known about the factors that contribute to fatigue in COPD. This review summarises existing knowledge on the prevalence of fatigue, factors related to fatigue and the instruments most commonly used to assess fatigue in COPD.

Worldwide Clinical Practice of High-Flow Nasal Cannula and Concomitant Aerosol Therapy in the Adult ICU Setting.

Background: High-flow nasal cannula (HFNC) oxygen therapy has been broadly used. However, no consensus has been achieved on the practical implementation of HFNC and how to provide aerosol delivery during HFNC therapy in adult patients.

Methods: An online anonymous questionnaire survey endorsed by 4 academic societies from America, Europe, mainland China, and Taiwan was administered from May to December 2019.

Current developments and future directions in respiratory physiotherapy.

Respiratory physiotherapists have a key role within the integrated care continuum of patients with respiratory diseases. The current narrative review highlights the profession's diversity, summarises the current evidence and practice, and addresses future research directions in respiratory physiotherapy. Herein, we describe an overview of the areas that respiratory physiotherapists can act in the integrated care of patients with respiratory diseases based on the Harmonised Education in Respiratory Medicine for European Specialists syllabus.

Generic and Respiratory-Specific Quality of Life in Non-Hospitalized Patients with COVID-19.

The impact of coronavirus disease 2019 (COVID-19) on quality of life appears to be highly underestimated, especially in patients who have not been admitted to the hospital. Therefore, our aim was to assess respiratory-specific quality of life in addition to generic quality of life in former patients with confirmed/suspected COVID-19 who have never been admitted to the hospital. Members of an online Belgian social support group for patients with confirmed/suspected COVID-19 with persistent complaints, completed an online survey.

Persistent symptoms 3 months after a SARS-CoV-2 infection: the post-COVID-19 syndrome?

Background: Many patients with COVID-19 did not require hospitalisation, nor underwent COVID-19 testing. There is anecdotal evidence that patients with "mild" COVID-19 may complain about persistent symptoms, even weeks after the infection. This suggests that symptoms during the infection may not resolve spontaneously.

Signaling pathways predisposing to chronic kidney disease progression.

The loss of functional nephrons after kidney injury triggers the compensatory growth of the remaining ones to allow functional adaptation. However, in some cases, these compensatory events activate signaling pathways that lead to pathological alterations and chronic kidney disease. Little is known about the identity of these pathways and how they lead to the development of renal lesions.
