Valvular and perivalvular thrombosis following self-expandable aortic valve replacement: analysis of 100 multi-detector computed tomography scans.

Aims: Subclinical thrombosis may represent an early stage of prosthesis structural disease. Most of the available evidence on the incidence, location, predictors, and consequences of thrombosis comes from studies that have employed balloon-expandable valves. We aimed to describe the different localisations of valvular and perivalvular thrombosis and analyse prosthesis-host multi-detector computed tomography predictors in the context of self-expandable prosthesis.

Implementation of the ISO 33405 requirements and production of a certified reference material for nitrofuran metabolites as incurred chicken muscle.

Certified reference materials (CRMs) contribute to the traceability of measurement results to recognized anchor points, ideally to the International System of Units (SI), and consequently, to their comparability and reliability. In the area of veterinary drugs' residues in foods of animal origin, the important role of CRMs must be highlighted, given the problems caused by trade restrictions in some countries. The results of studies concerning the certification of an incurred matrix certified reference material (IMCRM) for the mass fraction of nitrofuran metabolites in chicken muscles are presented in this work.

Criteria for Assessing Exposure to Biomechanical Risk Factors: A Research-to-Practice Guide-Part 1: General Issues and Manual Material Handling.

Musculoskeletal disorders are the most prevalent occupational health problem all over the world and are often related to biomechanical risk factors; to control these risk factors, several assessment methods (mostly observational) have been proposed in the past 40 years. An in-depth knowledge of each method to evaluate biomechanical risk factors is needed to effectively employ them in the field, together with a robust understanding of their effective predictive value and limitations. In Part 1, some general issues relevant to biomechanical risk assessment are discussed, and the method for assessing manual material handling after receiving more robust validation data is reviewed (Revised NIOSH Lifting Equation), together with a discussion about variability of tasks.

Furthering decent work by expanding the role of occupational safety and health.

Background: The International Labour Organization (ILO) and the United Nations (UN) have promoted the concept of decent work as a Sustainable Development Goal for 2030 to address critical global problems. Occupational safety and health (OSH) are components of decent work, primarily through the ILO social protection objective of the goal, and are linked to various other objectives.

Objective: This Commentary applies a previously published staging framework to stimulate thinking about how the OSH field can contribute further to the achievement of decent work.
