Systemic inflammation and lymphocyte activation precede rheumatoid arthritis.

Some autoimmune diseases, including rheumatoid arthritis (RA), are preceded by a critical subclinical phase of disease activity. Proactive clinical management is hampered by a lack of biological understanding of this subclinical 'at-risk' state and the changes underlying disease development. In a cross-sectional and longitudinal multi-omics study of peripheral immunity in the autoantibody-positive at-risk for RA period, we identified systemic inflammation, proinflammatory-skewed B cells, expanded Tfh17-like cells, epigenetic bias in naive T cells, TNF+IL1B+ monocytes resembling a synovial macrophage population, and CD4 T cell transcriptional features resembling those suppressed by abatacept (CTLA4-Ig) in RA patients.

Postoperative Complications of Direct-to-Implant and Two-Staged Breast Reconstruction: A Stratified Analysis.

Post-mastectomy implant-based reconstruction can be performed as direct-to-implant (DTI) or two-staged reconstruction (TSR). Rigorous studies have explored postoperative complications between TSR or DTI, yet few have stratified outcomes by relevant populations, pre-operative findings, mastectomy characteristics, or plane of implant placement. We sought to compare the outcomes between these cohorts at our institution.

Critical hematological parameters in bleeding during extracorporeal membrane oxygenation support.

Bleeding complications are frequently observed in patients undergoing extracorporeal membrane oxygenation and are associated with increased mortality. Due to the complex mechanisms, managing bleeding during ECMO remains a challenge. Acquired von Willebrand syndrome (AVWS) in ECMO highlights a potentially reduced affinity of von Willebrand factor (vWF) for binding to platelets and collagen in response to vascular damage, thus contributing to increased bleeding in ECMO patients.

Cannula-Associated Deep Vein Thrombosis Following Extracorporeal Membrane Oxygenation Decannulation: Incidence and Risk Factors.

Thrombotic complications during and after extracorporeal membrane oxygenation (ECMO) are commonly observed clinically. The incidences of cannula-associated deep vein thrombosis (CaDVT) post-ECMO support have predominantly focused on Caucasian demographics. This study aims to determine the incidence and risk factors for CaDVT in Vietnamese patients following ECMO decannulation.
