WNT-dependent interaction between inflammatory fibroblasts and FOLR2+ macrophages promotes fibrosis in chronic kidney disease.

Chronic kidney disease (CKD) is a public health problem driven by myofibroblast accumulation, leading to interstitial fibrosis. Heterogeneity is a recently recognized characteristic in kidney fibroblasts in CKD, but the role of different populations is still unclear. Here, we characterize a proinflammatory fibroblast population (named CXCL-iFibro), which corresponds to an early state of myofibroblast differentiation in CKD.

Toxic Shock Syndrome: A Literature Review.

Toxic shock syndrome (TSS) is a rare, life-threatening, toxin-mediated infectious process linked, in the vast majority of cases, to toxin-producing strains of or . The pathophysiology, epidemiology, clinical presentation, microbiological features, management and outcome of TSS are described in this review. Bacterial superantigenic exotoxins induces unconventional polyclonal lymphocyte activation, which leads to rapid shock, multiple organ failure syndrome, and death.

Impact of Multiplex PCR in the Therapeutic Management of Severe Bacterial Pneumonia.

Pneumonia is a common and severe illness that requires prompt and effective management. Advanced, rapid, and accurate tools are needed to diagnose patients with severe bacterial pneumonia, and to rapidly select appropriate antimicrobial therapy, which must be initiated within the first few hours of care. Two multiplex molecular tests, Unyvero HPN and FilmArray Pneumonia+ Panel, have been developed using the multiplex polymerase chain reaction (mPCR) technique to rapidly identify pathogens and their main antibiotic resistance mechanisms from patient respiratory specimens.

Comparison of Direct Oral Anticoagulants vs Vitamin K Antagonists After Transcatheter Mitral Valve Replacement.

Background: There is currently no established recommendation for antithrombotic treatment following transcatheter mitral valve replacement (TMVR). However, based on the analogy with surgical mitral bioprosthesis, vitamin K antagonists (VKAs) are predominantly used.

Objectives: The purpose of this study was to compare bleeding and thrombotic events associated with direct oral anticoagulants (DOACs) or VKAs in a prospective cohort of TMVR patients.

Quality of information and decision regrets during fertility-sparing management for atypical hyperplasia and endometrial cancer in a prospective cohort study.

Objective: To evaluate satisfaction with information, treatment, and decision regret during management to preserve fertility for atypical hyperplasia (AH) or endometrial cancer (EC).

Methods: A cohort study with standardized management using chlormadinone acetate was established through a national referral centre between January 2013 and November 2019. During this period, a questionnaire was given to 136 patients aged 19 to 43 years who were followed for fertility preservation for AH or EC.

Use of Aprotinin versus Tranexamic Acid in Cardiac Surgery Patients with High-Risk for Excessive Bleeding (APACHE) trial: a multicentre retrospective comparative non-randomized historical study.

Objectives: Following the reintroduction of aprotinin into the European market, the French Society of Cardiovascular and Thoracic Anaesthesiologists recommended its prophylactic use at half-dose for high-risk cardiac surgery patients. We examined whether the use of aprotinin instead of tranexamic acid could significantly reduce severe perioperative bleeding.

Methods: This multicentre, retrospective, historical study included cardiac surgery patients treated with aprotinin or tranexamic acid between December 2017 and September 2020.

Occurrences of post-traumatic stress disorder, anxiety, depression, and burnout syndrome in ICU staff workers after two-year of the COVID-19 pandemic: the international PSY-CO in ICU study.

Purpose: The present study aimed at assessing the prevalences of post-traumatic stress disorder (PTSD) (main objective), anxiety, depression, and burnout syndrome (BOS) and their associated factors in intensive care unit (ICU) staff workers in the second year of the COVID-19 pandemic.

Materials And Methods: An international cross-sectional multicenter ICU-based online survey was carried out among the ICU staff workers in 20 ICUs across 3 continents. ICUs staff workers (both caregivers and non-caregivers) were invited to complete PCL-5, HADS, and MBI questionnaires for assessing PTSD, anxiety, depression, and the different components of BOS, respectively.

Lack of association between HLA and asymptomatic SARS-CoV-2 infection.

Human genetic studies of critical COVID-19 pneumonia have revealed the essential role of type I interferon-dependent innate immunity to SARS-CoV-2 infection. Conversely, an association between the HLA-B*15:01 allele and asymptomatic SARS-CoV-2 infection in unvaccinated individuals was recently reported, suggesting a contribution of pre-existing T cell-dependent adaptive immunity. We report a lack of association of classical HLA alleles, including HLA-B*15:01, with pre-omicron asymptomatic SARS-CoV-2 infection in unvaccinated participants in a prospective population-based study in the US (191 asymptomatic vs.

Diagnosis and treatment of Tropheryma whipplei infection in patients with inflammatory rheumatic disease: Data from the French Tw-IRD registry.

Objectives: Tropheryma whipplei infection can manifest as inflammatory joint symptoms, which can lead to misdiagnosis of inflammatory rheumatic disease and the use of disease-modifying antirheumatic drugs. We investigated the impact of diagnosis and treatment of Tropheryma whipplei infection in patients with inflammatory rheumatic disease.

Methods: We initiated a registry including patients with disease-modifying antirheumatic drugs-treated inflammatory rheumatic disease who were subsequently diagnosed with Tropheryma whipplei infection.

U-net convolutional neural network applied to progressive fibrotic interstitial lung disease: Is progression at CT scan associated with a clinical outcome?

Background: Computational advances in artificial intelligence have led to the recent emergence of U-Net convolutional neural networks (CNNs) applied to medical imaging. Our objectives were to assess the progression of fibrotic interstitial lung disease (ILD) using routine CT scans processed by a U-Net CNN developed by our research team, and to identify a progression threshold indicative of poor prognosis.

Methods: CT scans and clinical history of 32 patients with idiopathic fibrotic ILDs were retrospectively reviewed.

Large-scale analysis of cell-cell communication reveals angiogenin-dependent tumor progression in clear cell renal cell carcinoma.

Cellular crosstalk in the tumor microenvironment (TME) is still largely uncharacterized, while it plays an essential role in shaping immunosuppression or anti-tumor response. Large-scale analyses are needed to better decipher cell-cell communication in cancer. In this work, we used original and publicly available single-cell RNA sequencing (scRNAseq) data to characterize in-depth the communication networks in human clear cell renal cell carcinoma (ccRCC).

Outcome of lung transplantation for adults with interstitial lung disease associated with genetic disorders of the surfactant system.

Background: Interstitial lung disease associated with genetic disorders of the surfactant system is a rare entity in adults that can lead to lung transplantation. Our objective was to describe the outcome of these patients after lung transplantation.

Methods: We conducted a retrospective, multicentre study, on adults who underwent lung transplantation for such disease in the French lung transplant centres network, from 1997 to 2018.

Quinolone Prophylaxis in Conjunction with Bacillus Calmette-Guérin Instillations for Bladder Cancer: Time To Reconsider the Evidence and Open the Quinolone Box?

Adjuvant bacillus Calmette-Guérin (BCG) instillations represent a cornerstone in the treatment of non-muscle-invasive bladder cancer. Instillation schedule and dose modifications have been evaluated in efforts to reduce the incidence of adverse events (AEs), but none so far has the same treatment efficacy as the full-dose recommended schedule. It has been shown that prophylactic quinolone use in conjunction with BCG instillations reduces AE incidence and improves timely completion of instillation regimens and patient survival.

Management of Adult Patients With Drug Reaction With Eosinophilia and Systemic Symptoms: A Delphi-Based International Consensus.

Importance: Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare but potentially fatal drug hypersensitivity reaction. To our knowledge, there is no international consensus on its severity assessment and treatment.

Objective: To reach an international, Delphi-based multinational expert consensus on the diagnostic workup, severity assessment, and treatment of patients with DRESS.
