Impact of ACIST CVi contrast delivery system on iodinated contrast media administration and waste.

The COVID-19 pandemic led to disruptions in iodinated contrast media (ICM) production and produced a global product shortage in the spring of 2022. The ACIST CVi system is an automated contrast injector system approved by the FDA for multi-patient dosing of ICM from a single container. A transition from the traditional manifold system for contrast injection to the ACIST CVi automated injector system in our cardiac angiographic labs during the COVID-19 pandemic led to reductions in contrast waste and cost while limiting patient exposure to ICM.

Risk of antimicrobial resistance spreading via food loss and waste.

BACKGROUND: While the agricultural sector is a known contributor to antimicrobial resistance (AMR), the potential role of food loss and waste (FLW) in AMR dissemination has been largely overlooked. FLW, a byproduct of inefficient food systems, poses economic, environmental, and food security challenges. It may also act as a reservoir and vector for antimicrobial resistance genes and antibiotic-resistant bacteria, contributing to the environmental spread of AMR if improperly managed. This narrative review assessed the presence, fate, and risks of AMR in FLW management. METHODS: Peer-reviewed s

Chemophysical Characterization of Carotenoproteins From Crustacean Shell Waste for Pharmaceutical Applications.

Commercial crustacean species represent some of the most economically valuable fishery products; however, their full potential remains underexploited due to the routine disposal of shellfish waste, which is rich in high-value bioactive compounds. Among these, carotenoid pigments have garnered increasing interest for their antioxidant and anti-inflammatory properties. In this study, we investigate the potential of recovering bioactive compounds from the shells of the European lobster (Homarus gammarus Linnaeus, 1758) and the Atlantic blue crab (Callinectes sapidus Rathbun, 1896), with a particu

Including advanced thermochemical technologies in comparative life cycle assessment (LCA) of municipal organic waste management systems: A systematic review.

Recently, municipalities worldwide have implemented selective collection systems for the organic fraction of municipal solid waste (OFMSW) to avoid the environmental impacts from landfilling organic matter and to promote resource recovery. Currently, biological methods such as anaerobic digestion (AD) predominate in source-separated OFMSW treatment. However, advanced thermochemical approaches - such as pyrolysis - have recently attracted considerable interest for treating OFMSW. While they offer some advantages over biological treatments, the environmental performance of advanced thermochemica

Bidirectional regulation of liver sinusoidal clearance by amino acid nanofibers and IGFBP4 complex: effects on HbA1c.

Therapies for type 2 diabetes primarily target hyperglycemia; however, complications are also triggered by advanced glycation end products (AGEs). We hypothesize that the anti-diabetic efficacy of insulin-like growth factor-binding protein 4 (IGFBP4) is enhanced when it assembles with a specific amino acid compound-2 (AAC2) into nanostructures. Their effects were examined in vitro and in ob/ob mice treated for 30 days with the AAC2-IGFBP4 complex or its individual components. IGFBP4-mediated glucose uptake in human and mouse preadipocytes was enhanced by complex formation with AAC2. This compl

Tackling the increasing contamination of the water supply by iodinated contrast media.

Contrast media are essential for diagnostic and interventional procedures. Iodinated contrast media are the most commonly used agents, with CT requiring the largest overall quantities. Data show that these iodinated contrast media are found in sewage water, surface water and drinking water in many regions in the world. Because standard drinking water purification techniques only provide poor to moderate removal of iodinated contrast media, these substances pose a problem for drinking water preparation that has not yet been solved. There is a growing body of evidence supporting the negative env

Iron sulphides mediated autotrophic denitrification: An emerging bioprocess for nitrate pollution mitigation and sustainable wastewater treatment.

Iron sulphides, mainly in the form of mackinawite (FeS), pyrrhotite (Fe1-xS, x = 0-0.125) and pyrite (FeS2), are the most abundant sulphide minerals and can be oxidized under anoxic and circumneutral pH conditions by chemoautotrophic denitrifying bacteria to reduce nitrate to N2. Iron sulphides mediated autotrophic denitrification (ISAD) represents an important natural attenuation process of nitrate pollution and plays a pivotal role in linking nitrogen, sulphur and iron cycles in a variety of anoxic environments. Recently, it has emerged as a promising bioprocess for nutrient removal from var

Effect of iron sulphate on the phosphorus speciation from agro-industrial sludge based and sewage sludge based compost.

Composting is considered a suitable process for organic waste management, providing stable products that can be safely utilized as fertilizers, but little is still known about the variation of phosphorous (P) extractability during the stabilization process. In this work, sequential chemical extraction (SCE) with increasing strength extractants (H2O; 0.5M NaHCO3 pH 8.5; 0.1M NaOH, 1M HCl) was applied for P speciation over 56days of composting of either agro-industrial or urban wastewater sludge with green waste treated (AICFe+; SSCFe+) or not (AICFe-; SSCFe-) with FeSO4 (2%v/v). Composting stro
