Cardio pulmonary resuscitation (CPR) in the frail and those with multiple health conditions: Outcomes before and during the COVID pandemic.

Coronavirus 2019 (COVID-19)-era resuscitation guidelines advised personal protective equipment before chest compressions and proactive advanced care planning. We investigated the impact of COVID-19 on cardiopulmonary resuscitation (CPR) outcomes according to scoring of frailty and of multiple health conditions. A retrospective single-centre analysis of clinical and electronic records for all adult cardiac arrest calls on wards between June 2020 and June 2021 was performed.

Effects of polystyrene nanoplastics exposure on in vitro-grown Stevia rebaudiana plants.

Nanoplastics (NPs) as environmental contaminants have received increased attention in recent years. Numerous studies have suggested possible negative effects of plants exposure to NPs, but more data are needed with various plants under different exposure conditions to clarify the underlying phytotoxicity mechanisms. In this study, we investigated the effect of polystyrene nanoplastics (PSNPs; 28.

Silver Nanostar-Based SERS for the Discrimination of Clinically Relevant and Species and Clones.

The development of rapid, reliable, and low-cost methods that enable discrimination among clinically relevant bacteria is crucial, with emphasis on those listed as WHO Global Priority 1 Critical Pathogens, such as carbapenem-resistant and carbapenem-resistant or ESBL-producing . To address this problem, we developed and validated a protocol of surface-enhanced Raman spectroscopy (SERS) with silver nanostars for the discrimination of and species, and their globally disseminated and clinically relevant antibiotic resistant clones. Isolates were characterized by mixing bacterial colonies with silver nanostars, followed by deposition on filter paper for SERS spectrum acquisition.

Interface-Dependent Selectivity in Plasmon-Driven Chemical Reactions.

Plasmonic nanoparticles can drive chemical reactions powered by sunlight. These processes involve the excitation of surface plasmon resonances (SPR) and the subsequent charge transfer to adsorbed molecular orbitals. Nonetheless, controlling the flow of energy and charge from SPR to adsorbed molecules is still difficult to predict or tune.

Stage related metabolic profile of the synovial fluid in patients with acute flares of knee osteoarthritis.

Background And Aim: Osteoarthritis (OA) is the most common joint condition and the leading cause of pain and disability in elderly patients. Currently, there is no biomarker available for the early diagnosis of OA, and limited data is available regarding the molecular basis of progression for OA. For this reason, this study aimed to identify the metabolomic profile of early and late OA using high-performance liquid chromatography coupled with untargeted mass spectrometry (LC-MS).
