New onset atrial fibrillation post-transcatheter aortic valve implantation (TAVI) is common and is associated with adverse outcomes. However, silent atrial fibrillation (AF) is poorly documented in the context. This study sought to evaluate the incidence, predictive factors, and prognostic value of Silent AF post-TAVI. All the consecutive patients with TAVI were prospectively analyzed by continuous electrocardiogram monitoring≥48 hours after implantation. Silent AF was defined as asymptomatic episodes lasting at least 30 seconds. The population was divided into 3 groups: history of AF, no-AF, and silent AF. Among the 206 patients implanted with TAVI, 19 (16.1%) developed silent AF. Compared with the no-AF group, patients with silent AF shared the same clinical characteristics and cardiovascular risk factors. Procedural success and echography parameters after the device implantation were similar between groups. Left atrial volume was significantly increased (p <0.001) in the silent AF group, together with preimplantation C-reactive protein (CRP) >3 mg/L and glucose (p = 0.048 and p = 0.002). By multivariate analysis, CRP >3 mg/dl and logistic European System for Cardiac Operative Risk Evaluation were identified as independent predictors of silent AF. In-hospital and 1-year mortalities were higher in pre-existing AF patients, whereas no-AF and the silent AF patients share the same prognosis. Our prospective study showed for the first time that silent AF is frequent after TAVI procedures. In conclusion, our work suggests that CRP could help to predict the risk of developing silent AF. However, the onset of silent AF is not associated with worse prognosis in the year following the procedure in our study.

Solitary fibrous tumours (SFTs) are rare soft tissue masses that are often clinically silent until they cause mass effect. A paraneoplastic syndrome manifesting as persistent hypoglycaemia, termed Doege-Potter syndrome (DPS), can be associated with these lesions. Surgical treatment is recommended for the management of these tumours.

Early detection of hepatitis C virus (HCV) infection is crucial for eliminating this silent killer, especially in resource-limited settings. HCV core antigen (HCVcAg) represents a promising alternative to the current "gold standard" HCV RNA assays as an active viremia biomarker. Herein, a highly sensitive electrochemical magneto-immunosensor for the HCVcAg was developed.

To investigate the role of silent information regulator 6 (SIRT6) in regulating podocyte injury in diabetic nephropathy (DN) through autophagy mediated by Notch signaling pathway. A blank control group (group A), a diabetic nephropathy group (group B), and a Sirt6 intervention group (group C) were established. The group A cells were human normal glomerular podocyte cell lines (HGPCs) without any treatment.

Background And Aims: Self-expandable metal stents (SEMS) are effective in alleviating malignant colorectal obstruction. However, bowel perforation following SEMS placement remains a significant concern, as it can adversely affect oncological outcomes. This study aimed to evaluate the recurrence and overall survival rates associated with SEMS-related bowel perforations.

Returning results to participants of environmental exposure studies has become more common in recent years. Despite evidence of benefits for study participants, there are challenges in communicating results to people with limited resources or capacity to mitigate chemical exposures. We interviewed N=54 participants and compared exposure report-back conducted in 2010-2013 across three susceptible study populations: 1) low-income pregnant individuals in the Chemicals in Our Bodies (CIOB) study; 2) the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS) cohort; and 3) early childhood educators (ECE).
