Global assessment of marine plastic exposure risk for oceanic birds.

Plastic pollution is distributed patchily around the world's oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters plastic is crucial for targeting research and mitigation.

Adding access blood flow surveillance reduces thrombosis and improves arteriovenous fistula patency: a randomized controlled trial.

Purpose: Stenosis is the main cause of arteriovenous fistula (AVF) failure. It is still unclear whether surveillance based on vascular access blood flow (QA) enhances AVF function and longevity.

Methods: We conducted a three-year follow-up randomized, controlled, multicenter, open-label trial to compare QA-based surveillance and pre-emptive repair of subclinical stenosis with standard monitoring/surveillance techniques in prevalent mature AVFs.

The impact of access blood flow surveillance on reduction of thrombosis in native arteriovenous fistula: a randomized clinical trial.

Purpose: The usefulness of access blood flow (QA) measurement is an ongoing controversy. Although all vascular access (VA) clinical guidelines recommend monitoring and surveillance protocols to prevent VA thrombosis, randomized clinical trials (RCTs) have failed to consistently show the benefits of QA-based surveillance protocols. We present a 3-year follow-up multicenter, prospective, open-label, controlled RCT, to evaluate the usefulness of QA measurement using Doppler ultrasound (DU) and ultrasound dilution method (UDM), in a prevalent hemodialysis population with native arteriovenous fistula (AVF).

Risk Assessment of Tuberculosis in Contacts by IFN-γ Release Assays. A Tuberculosis Network European Trials Group Study.

Rationale: Latent infection with Mycobacterium tuberculosis is defined by a positive IFN-γ release assay (IGRA) result in the absence of active tuberculosis. Only few, mostly monocentric studies have evaluated the role of IGRAs to predict the development of tuberculosis in recent contacts in low-incidence countries of tuberculosis.

Objectives: To analyze IGRA results and the effect of preventive chemotherapy on tuberculosis progression rates among recent contacts.

[Biomarkers of vascular inflammation and subclinical atherosclerosis in the metabolic syndrome].

Background And Objective: The metabolic syndrome (MS) is linked to an increase of cardiovascular mortality and morbidity, the pathological substrate of cardiovascular events being atherosclerosis. Inflammatory phenomena play a role in the genesis of atherosclerosis. The aim of this study was to analyze the vascular (adhesins) and systemic [interleukins, amyloid A serum protein (AAS), C reactive protein (PCR)] inflammation markers as well as hemodynamic parameters and the presence or absence of subclinical atherosclerosis measured by intima-media thickness (TIM) determination in MS.
