Systematic literature review informing the EULAR recommendations for the non-pharmacological management of systemic lupus erythematosus and systemic sclerosis.

Through this systematic literature review, we assembled evidence to inform the EULAR recommendations for the non-pharmacological management of systemic lupus erythematosus (SLE) and systemic sclerosis (SSc). We screened articles published between January 2000 and June 2021. Studies selected for data extraction (118 for SLE and 92 for SSc) were thematically categorised by the character of their intervention.

Gastrointestinal involvement in adult IgA vasculitis (Henoch-Schönlein purpura): updated picture from a French multicentre and retrospective series of 260 cases.

Objectives: To describe the clinical presentation, treatments and prognosis of gastrointestinal (GI) involvement in adult IgA vasculitis (IgAV).

Methods: Data from 260 adults with IgAV included in a French multicentre retrospective survey were analysed. Presentation and outcomes of patients with (GI+) and without (GI-) GI involvement were compared.

[Rheumatoid arthritis : cardiovascular and pulmonary manifestations].

Rheumatoid arthritis (RA) often affects extra-articular structures. Treatments used for arthritis are often also effective on the extra-articular manifestations, but exceptions are numerous, particularly for cardiovascular and pulmonary problems. Cardiovascular disorders mainly include complications related to atherosclerosis : they are probably the main contributor to the increased mortality observed in RA, must be specifically taken into account and largely determine the choice of treatments used to treat RA.

Inflammasome Adaptor ASC Suppresses Apoptosis of Gastric Cancer Cells by an IL18-Mediated Inflammation-Independent Mechanism.

Inflammasomes are key regulators of innate immunity in chronic inflammatory disorders and autoimmune diseases, but their role in inflammation-associated tumorigenesis remains ill-defined. Here we reveal a protumorigenic role in gastric cancer for the key inflammasome adaptor apoptosis-related speck-like protein containing a CARD (ASC) and its effector cytokine IL18. Genetic ablation of ASC in the spontaneous mouse model of intestinal-type gastric cancer suppressed tumorigenesis by augmenting caspase-8-like apoptosis in the gastric epithelium, independently from effects on myeloid cells and mucosal inflammation.

Postmortem evaluation of cholesterol, triglyceride, and apolipoprotein levels.

Cholesterol and triglyceride levels have been analyzed in the forensic setting and their values correlated with atherosclerotic lesions found at autopsy and histology. Nevertheless, the results of these investigations have provided diverging information on postmortem molecule stability and postmortem measurement reliability. The aim of this study was to determine triglycerides, total cholesterol, low-density and high-density lipoprotein cholesterol, apolipoprotein B, and apolipoprotein A-I in antemortem and postmortem serum samples in a series of cases (N = 10, including cardiac and noncardiac deaths) that underwent forensic investigations and had both samples available, measure the same molecules in postmortem serum from femoral blood and pericardial and pleural fluids (N = 39, including cardiac and noncardiac deaths), and evaluate whether different levels of these molecules could be observed in cases characterized by different degrees of coronary artery atherosclerosis (N = 39, including cardiac and noncardiac deaths).

Characteristics and Management of IgA Vasculitis (Henoch-Schönlein) in Adults: Data From 260 Patients Included in a French Multicenter Retrospective Survey.

Objective: Data on adult IgA vasculitis (Henoch-Schönlein) (IgAV) are scarce. This survey was designed to better define the clinical spectrum of IgAV and efficacy of treatments in a French patient population.

Methods: Data on clinical characteristics, histologic features, and treatment response from 260 patients with IgAV included in a French multicenter retrospective survey were analyzed.

Life-threatening NLRC4-associated hyperinflammation successfully treated with IL-18 inhibition.

NLRC4-inflammasome hyperactivity causes infantile-onset Macrophage Activation Syndrome and enterocolitis with extraordinary serum IL-18 elevation (NLRC4-MAS). Herein, we report a critically ill infant with severe, refractory NLRC4-MAS who showed sustained response to treatment with experimental IL-18 inhibition.

Elevated serum levels of free interleukin-18 in adult-onset Still's disease.

Objective: IL-18 is a pro-inflammatory cytokine of the IL-1 family that is naturally inhibited by IL-18 binding protein (IL-18BP). High levels of IL-18 have been described in the serum of adult-onset Still's disease (AOSD) patients, but only total IL-18 levels (including inactive IL-18 bound to IL-18BP) have been measured. With a specific immunoassay, we aimed to measure free IL-18 serum levels in AOSD patients and other rheumatic diseases.

Tracheobronchial Stenoses in Granulomatosis With Polyangiitis (Wegener's): A Report on 26 Cases.

Tracheobronchial stenoses (TBSs) are potentially severe manifestations of granulomatosis with polyangiitis (Wegener's) (GPA) that usually respond poorly to corticosteroids and immunosuppressive agents. We describe 26 GPA patients with ≥1 tracheal (mainly subglottic, SGS) and/or bronchial stenosis(ses) (BS(s)).Sixteen patients had solitary SGS and 10 had ≥1 BS(s).

Granulomatosis with polyangiitis: endoscopic management of tracheobronchial stenosis: results from a multicentre experience.

Objectives: Tracheobronchial stenosis (TBS) is noted in 12-23% of patients with granulomatosis with polyangiitis (GPA), and includes subglottic stenosis and bronchial stenosis. We aimed to analyse the endoscopic management of TBS in GPA and to identify factors associated with the efficacy of endoscopic interventions.

Methods: We conducted a French nationwide retrospective study that included 47 patients with GPA-related TBS.

Bilateral angle-closure glaucoma and multifocal choroiditis as a first presentation in hodgkin lymphoma.

Purpose: To report atypical ocular manifestations in two patients with undiagnosed Hodgkin lymphoma.

Methods: Observational case report.

Results: The first patient, a 27-year-old man, presented with bilateral acute angle-closure glaucoma secondary to uveal effusion.

Atlantic leatherback migratory paths and temporary residence areas.

Background: Sea turtles are long-distance migrants with considerable behavioural plasticity in terms of migratory patterns, habitat use and foraging sites within and among populations. However, for the most widely migrating turtle, the leatherback turtle Dermochelys coriacea, studies combining data from individuals of different populations are uncommon. Such studies are however critical to better understand intra- and inter-population variability and take it into account in the implementation of conservation strategies of this critically endangered species.

Yield of bone marrow examination in diagnosing the source of fever of unknown origin.

Background: Fever of unknown origin (FUO) still remains a diagnostic challenge, while diagnosis may remain obscure for several weeks or months. The role of tissue biopsy is crucial in the diagnostic approach. We report a series of 130 consecutive patients with FUO who had undergone a bone marrow biopsy (BMB).

Marine turtles use geomagnetic cues during open-sea homing.

Marine turtles are renowned long-distance navigators, able to reach remote targets in the oceanic environment; yet the sensory cues and navigational mechanisms they employ remain unclear [1, 3]. Recent arena experiments indicated an involvement of magnetic cues in juvenile turtles' homing ability after simulated displacements [4, 5], but the actual role of geomagnetic information in guiding turtles navigating in their natural environment has remained beyond the reach of experimental investigations. In the present experiment, twenty satellite-tracked green turtles (Chelonia mydas) were transported to four open-sea release sites 100-120 km from their nesting beach on Mayotte island in the Mozambique Channel; 13 of them had magnets attached to their head either during the outward journey or during the homing trip.
