Cellular and Molecular Mechanisms Leading to Air Travel-Induced Thrombosis.

Venous thromboembolism, characterized by deep vein thrombosis and pulmonary embolism, is the third cardiovascular disease in the world. Deep vein thrombosis occurs when a blood clot forms in areas of impaired blood flow, and it is significantly affected by environmental factors. Local hypoxia, caused by venous stasis, plays a critical role in deep vein thrombosis under normal conditions, and this effect is intensified when the Po decreases, such as during air travel or high-altitude exposure.

Usefulness of monitoring mycophenolic acid exposure in systemic sclerosis-related interstitial lung disease: a retrospective cohort study.

Background: Systemic sclerosis-related interstitial lung disease (SSc-ILD) represents a significant cause of morbidity and mortality in Systemic Sclerosis (SSc). Mycophenolate mofetil (MMF) is currently the first line treatment for SSc-ILD. There is no recommendation on the dosage of mycophenolic acid (MPA) blood concentrations, so we aimed to study the correlation between MPA exposure and respiratory outcomes in this population.

Targeting BTN2A1 Enhances Vγ9Vδ2 T-Cell Effector Functions and Triggers Tumor Cell Pyroptosis.

Vγ9Vδ2 T cells are potent but elusive cytotoxic effectors. Butyrophilin subfamily 2 member A1 (BTN2A1) is a surface protein that has recently been shown to bind the Vγ9 chain of the γδ T-cell receptor, but its precise role in modulating Vγ9Vδ2 T-cell functions remains unknown. Here, we show that 107G3B5, a monoclonal BTN2A1 agonist antibody, was able to significantly enhance Vγ9Vδ2 T-cell functions against hematologic or solid cell lines and against primary cells from patients with adult acute lymphoblastic leukemia.

Effects of CO₂ on the occurrence of decompression sickness: review of the literature.

Introduction: Inhalation of high concentrations of carbon dioxide (CO₂) at atmospheric pressure can be toxic with dose-dependent effects on the cardiorespiratory system or the central nervous system. Exposure to both hyperbaric and hypobaric environments can result in decompression sickness (DCS). The effects of CO₂ on DCS are not well documented with conflicting results.

Interest of thoracic ultrasound after cardiac surgery or interventional cardiology.

Thoracic ultrasound has attracted much interest in detecting pleural effusion or pulmonary consolidation after cardiac surgery. In 2016, Trovato reported, in the , the interest of using, in addition to echocardiography, thoracic ultrasound. In this editorial, we highlight the value of assessing diaphragm function after cardiac surgery and interventional cardiology procedures.

Diaphragm movement sensor for phrenic nerve monitoring during cryoballoon procedures: the first clinical evaluation.

Background And Aims: Right phrenic nerve palsy is the most frequent complication of cryoballoon procedures. The SMARTFREEZE™ console (Boston Scientific, St. Paul, MN, USA) has integrated a new tool for diaphragm monitoring-the Diaphragm Movement Sensor; however, it has not been evaluated in clinical practice.

Late Post-Dissection Dynamic Intermittent Malperfusion of the Aortic Arch in Association with a Rare Heterogenous LOX Gene Variation.

Late ischaemic consequences of type A aortic dissection are rare. We present a 6-year late complication of type A aortic dissection treated by Bentall surgery in a 41-year-old patient. The patient presented with several episodes of lipothymia associated with hypertensive attacks with anisotension, cervicalgia, hemicranial headache, abdominal pain and lower limb slipping initially on exertion and later at rest.

Persistent COVID-19: A Case Report of an Immunocompromised Patient and a Literature Review.

Introduction: Immunocompromised patients can show prolonged shedding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and persistent symptoms, which is called persistent COVID-19.

Case Presentation: We report a case of an immunocompromised patient who was treated for mantle cell lymphoma and was suffering from B-cell depletion. The patient developed persistent COVID-19, which was confirmed by real-time polymerase chain reaction (RT-PCR) tests in only sputum and bronchoalveolar fluid which remained positive for at least 112 days.

Post-Harvest Atmospheric Pressure and Composition Modify the Concentration and Bioaccessibility of - and -Carotene in Carrots and Sweet Potatoes.

Provitamin A (proVA) carotenoid synthesis and degradation are strongly influenced by environmental factors, including during post-harvest storage. Hypobaric and hyperbaric storages increase the shelf-life of many crops, but their effects on proVA carotenoids are not known. Our aim was to investigate the effects of modifications of atmospheric pressure and composition on - and -carotene concentration and bioaccessibility during the post-harvest storage of carrots and sweet potatoes.

A thrombus is formed by a gradient of platelet activation and procoagulant endothelium.

Background: The contribution of platelets in thrombosis within microcirculation has been extensively documented in the literature. We previously showed, , that platelet activation revealed by intracellular calcium mobilization was a crucial step in the growth of thrombi following laser-induced injury, a model of thromboinflammation.

Objective: Our goal was to investigate the extent of platelet activation and the spatial distribution of platelets throughout a growing thrombus.

Clinical, biological, electrophysiological and therapeutic profile of patients with anti-MAG neuropathy according to MYD88 and CXCR4 mutations and underlying haemopathy.

Introduction: Anti-MAG neuropathies are associated with an IgM monoclonal gammopathy of undetermined significance (MGUS) or with a malignant haemopathy. Our objective was to determine whether the presence of a haemopathy or somatic mutations of MYD88 and CXCR4 genes influences disease presentation and response to rituximab (RTX).

Methods: We included 79 patients (mean age 74 years, disease duration 9.

Net clinical benefit of dual antiplatelet therapy in elderly patients with acute coronary syndrome: A systematic review and meta-analysis.

Background: Contemporary dual antiplatelet therapy (DAPT) strategies, such as short-term DAPT or de-escalation of DAPT, have emerged as attractive strategies to treat patients with acute coronary syndrome (ACS). However, it remains uncertain whether they are suitable for elderly patients.

Methods: PubMed, Embase, and Cochrane CENTRAL databases were searched in September 2022.

Anti-Jo-1 autoantibodies: biomarkers of severity and evolution of the disease in antisynthetase syndrome.

Background: Anti-Jo-1 autoantibodies represent essential markers in the diagnosis of antisynthetase syndrome (ASS). In this retrospective study, we aimed to investigate whether their concentrations and fluctuations could both respectively reflect the severity and evolution of ASS.

Methods: Between 2015 and 2020, clinical and biological features of ASS patients with at least one positive measure of anti-Jo-1 autoantibody were collected.

Fluorinated Benzofuran and Dihydrobenzofuran as Anti-Inflammatory and Potential Anticancer Agents.

Benzofuran and 2,3-dihydrobenzofuran scaffolds are heterocycles of high value in medicinal chemistry and drug synthesis. Targeting inflammation in cancer associated with chronic inflammation is a promising therapy. In the present study, we investigated the anti-inflammatory effects of fluorinated benzofuran and dihydrobenzofuran derivatives in macrophages and in the air pouch model of inflammation, as well as their anticancer effects in the human colorectal adenocarcinoma cell line HCT116.
