SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2023; 300:122897. [PMID: 37229942 DOI: 10.1016/j.saa.2023.122897] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 03/15/2023] [Accepted: 03/23/2023] [Indexed: 05/27/2023]
Abstract
The abuse of benzodiazepines is a serious health hazard that can cause damage to the central nervous system.Trace monitoring of benzodiazepines in serum can effectively prevent the damage caused by these drugs. Therefore, in this study, a Fe3O4@PDA@Au core-shell satellite nanomaterial SERS(Surface-Enhanced Raman Scattering) probe that integrates magnetic separation techniques and a multi-hotspot structure was synthetized by in situ growth of gold nanoparticles on the surface of PDA(Polymerized dopamine)-coated Fe3O4. The size and gap of Au nanoparticles on the surface of the SERS probe can be modulated by regulating the amount of HAuCl4 to create 3D multi-hotspot structures. The good dispersion and superparamagnetic properties of this SERS probe enable it to fully contact and load the target molecules in the serum, and the applied magnetic field facilitates separation and enrichment.This process increases the molecular density and number of SERS hotspots, thereby enhancing detection sensitivity. Based on the above considerations, this SERS probe can detect traces of eszopiclone and diazepam in serum at concentrations as low as 1 μg/ml with good linearity, offering promising applications in clinical monitoring of drug concentrations in blood.

Process Evaluation of the SImplification of Medications Prescribed to Long-tErm Care Residents (SIMPLER) Cluster Randomized Controlled Trial: A Mixed Methods Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18115778. [PMID: 34072223 PMCID: PMC8199013 DOI: 10.3390/ijerph18115778] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 05/19/2021] [Accepted: 05/25/2021] [Indexed: 02/01/2023]
Abstract
Complex medication regimens are highly prevalent, burdensome for residents and staff, and associated with poor health outcomes in residential aged care facilities (RACFs). The SIMPLER study was a non-blinded, matched-pair, cluster randomized controlled trial in eight Australian RACFs that investigated the one-off application of a structured 5-step implicit process to simplify medication regimens. The aim of this study was to explore the processes underpinning study implementation and uptake of the medication simplification intervention. A mixed methods process evaluation with an explanatory design was undertaken in parallel with the main outcome evaluation of the SIMPLER study and was guided by an established 8-domain framework. The qualitative component included a document analysis and semi-structured interviews with 25 stakeholders (residents, family, research nurses, pharmacists, RACF staff, and a general medical practitioner). Interviews were transcribed verbatim and reflexively thematically content analyzed. Descriptive statistics were used to summarize quantitative data extracted from key research documents. The SIMPLER recruitment rates at the eight RACFs ranged from 18.9% to 48.6% of eligible residents (38.4% overall). Participation decisions were influenced by altruism, opinions of trusted persons, willingness to change a medication regimen, and third-party hesitation regarding potential resident distress. Intervention delivery was generally consistent with the study protocol. Stakeholders perceived regimen simplification was beneficial and low risk if the simplification recommendations were individualized. Implementation of the simplification recommendations varied between the four intervention RACFs, with simplification implemented at 4-month follow-up for between 25% and 86% of residents for whom simplification was possible. Good working relationships between stakeholders and new remunerated models of medication management were perceived facilitators to wider implementation. In conclusion, the one-off implicit medication simplification intervention was feasible and generally delivered according to the protocol to a representative sample of residents. Despite variable implementation, recommendations to simplify complex regimens were valued by stakeholders, who also supported wider implementation of medication simplification in RACFs.
