Background: The public commonly calls 911 for unintentional ingestions, rather than calling the local poison center. By utilizing a series of scripted questions, 911 dispatchers in Los Angeles determine if an ingestion meets "omega-1" classification. Under such circumstances, the regional poison center is contacted prior to dispatch of paramedics. If the poison center advises that the patient can remain at home, EMS is not dispatched and the patient is followed at home by the poison center. The primary objective is to determine the number of averted transports through involvement of a poison center. A secondary objective is to determine the potential costs and charges saved with the use of such a strategy.
Methods: A retrospective review of all overdose calls with an "omega-1" classification to a single EMS system between 1/2008-6/2012. Each call culminating in an EMS dispatch was subsequently reviewed by two additional reviewers. The cost savings was determined by utilizing data from the Medical Expenditure Panel Survey (MEPS) from 2000 to 2010. Monetary values were adjusted to 2012 dollars.
Results: Three hundred eighteen cases received "omega-1" dispatch classification. EMS was dispatched 19 times (5.98 %), and 11 patients (3.46 %) were ultimately transported. The most common reasons for transport were ambiguity over the ingested agent or amount, and caller insistence. Using these estimates, routine consultation of a regional poison center as part of EMS dispatch averted $486,595 in charges, and $183,279 in payments.
Conclusions: Routine consultation of a poison center by emergency medical dispatchers can reduce unnecessary dispatches, ambulance transports, and ED visits with significant associated cost savings.

The issue of plastic pollutants has become a growing concern. Both microplastics (MPs) (particle size < 5 mm) and nanoplastics (NPs) (particle size < 1 µm) can cause DNA damage, cytotoxicity, and oxidative stress in various organisms. The primary known impacts of microplastic/nanoplastic are observed in the liver and respiratory system, leading to hepatotoxicity and chronic obstructive pulmonary disease.

Electrochemical oxidation of small molecules shows great promise to substitute oxygen evolution reaction (OER) or hydrogen oxidation reaction (HOR) to enhance reaction kinetics and reduce energy consumption, as well as produce high-valued chemicals or serve as fuels. For these oxidation reactions, high-valence metal sites generated at oxidative potentials are typically considered as active sites to trigger the oxidation process of small molecules. Isolated atom site catalysts (IASCs) have been developed as an ideal system to precisely regulate the oxidation state and coordination environment of single-metal centers, and thus optimize their catalytic property.

Microplastics (MPs) are ubiquitous environmental pollutants that have garnered significant attention due to their small particle size, resistance to degradation and large specific surface area, which makes it easy to adsorb various pollutants, particularly heavy metals. Arsenic (As), a common metal poisons, poses significant risks due to its widespread industrial use. When MPs and As co-exist in the environment, they can exert combined toxic effects on organisms, affecting various systems, including the nervous system.

Background: Ochratoxin A (OTA) is toxic secondary metabolites produced by fungi and can pose a serious threat to food safety and human health. Due to the high stability and toxicity, OTA contamination in agricultural products is of great concern. Therefore, the development of a highly sensitive and reliable OTA detection method is crucial to ensure food safety.
