Strategies to Reduce Frequent Emergency Department Use among Persons Experiencing Homelessness with Mental Health Conditions: a Scoping Review.

The USA has some of the highest utilization rates of the Emergency Department (ED) worldwide, leading to increased healthcare costs, constrained resources, and fragmented care. Many of the highest ED utilizers are persons experiencing homelessness (PEH) and those with mental health conditions, with even higher use by those with comorbid social challenges. This study reviewed the literature assessing interventional approaches in the ED to minimize the burden of ED utilization by PEH with associated mental health conditions.

Quantitation of insulin injection by high-performance liquid chromatography and high-performance capillary electrophoresis.

High-performance capillary electrophoresis (HPCE) was evaluated as a potential technique for the regulatory analysis of commercial dosage forms of insulin. A comparison was made to a liquid chromatographic analysis presently being proposed as an official monograph in the United States Pharmacopeia. The salient points of this comparison were accuracy, precision and ease of use.

Determination of iodide and thiosulfate by paired-ion, reversed-phase high-performance liquid chromatography with ultraviolet absorbance, electrochemical, and conductimetric detection.

Inorganic anions are typically determined by ion chromatography, ion-selective electrodes, or by "wet chemical" procedures. An alternative to these approaches is afforded by paired-ion, reversed-phase high-performance liquid chromatography (HPLC), and the application of this technique to the determination of iodide and thiosulfate is discussed. Each analyte can be determined using ultraviolet (UV) absorbance detection and oxidative, amperometric electrochemical detection (ED).

High pressure liquid chromatographic determination of antihistamine-adrenergic combination products: collaborative study.

A reverse phase high pressure liquid chromatographic method in which ion-pairing is used for the determination of combinations of pseudoephedrine hydrochloride with triprolidine hydrochloride or chlorpheniramine maleate in syrups and tablets was collaboratively studied by 8 laboratories. Collaborators were supplied with 12 samples including synthetic and commercial syrup formulations and commercial tablet composites. Mean recoveries of pseudoephedrine hydrochloride and triprolidine hydrochloride from synthetic syrup formulations were 100.
