AI Article Synopsis
- Monitoring fungal contamination in hospitals is crucial to prevent invasive aspergillosis (IA), especially during major construction like the demolition at Edouard Herriot Hospital in 2015, which involved ongoing care nearby.
- Environmental surveys were conducted daily in eight adjacent hospital wards to track fungal loads, using agar impact samplers and monitoring factors like temperature and humidity.
- The study aims to enhance current hospital environmental monitoring methods and improve IA risk management during construction while being ethically approved for research dissemination.
Article Abstract
Introduction: Monitoring fungal aerocontamination is an essential measure to prevent severe invasive aspergillosis (IA) infections in hospitals. One central block among 32 blocks of Edouard Herriot Hospital (EHH) was entirely demolished in 2015, while care activities continued in surrounding blocks. The main objective was to undertake broad environmental monitoring and clinical surveillance of IA cases to document fungal dispersion during major deconstruction work and to assess clinical risk.
Methods And Analysis: A daily environmental survey of fungal loads was conducted in eight wards located near the demolition site. Air was collected inside and outside selected wards by agar impact samplers. Daily spore concentrations were monitored continuously by volumetric samplers at a flow rate of 10 L.min. Daily temperature, wind direction and speed as well as relative humidity were recorded by the French meteorological station Meteociel. strains stored will be genotyped by multiple-locus, variable-number, tandem-repeat analysis. Antifungal susceptibility will be assessed by E-test strips on Roswell Park Memorial Institute medium supplemented with agar. Ascertaining the adequacy of current environmental monitoring techniques in hospital is of growing importance, considering the rising impact of fungal infections and of curative antifungal costs. The present study could improve the daily management of IA risk during major deconstruction work and generate new data to ameliorate and redefine current guidelines.
Ethics And Dissemination: This study was approved by the clinical research and ethics committees of EHH.

Context: The healthcare industry faces a critical shortage of qualified physicians. To address this growing concern, medical schools nationwide are increasing their efforts to recruit and train premedical students to fill this gap. Those efforts include adequately preparing premedical students with the competencies and skills to meet the application requirements and gain acceptance to the medical school of their choosing.

Synthetic polymers have found widespread use with functional lifetimes from seconds to decades. However, the lack of end-of-life treatment for these plastics is causing a significant environmental and human health crisis due to their persistence and bioaccumulation. Upcycling post-consumer plastic waste to products with inherent recyclability is an attractive strategy to tackle this problem, as it can broaden the range of accessible materials and uncover unprecedented features while dealing with current plastic waste.

This study utilized deep eutectic solvents (DES) based on choline chloride/lactic acid (ChCl/LA) to deconstruct coconut fibers. The effects of DES with different temperatures and molar ratios on the yield of lignin, recovery rate of residues, structural changes in lignin and solid residues, and saccharification efficiency were investigated. The results showed that acidic DES treatment effectively deconstructed the coconut fibers, resulting in a high lignin yield of 68.

By adopting a constructivist approach, particularly through the lens of Social Representation Theory (SRT), these studies explore the ways in which geopolitical contexts shape decolonial activism within psychological and scientific discourse. The first study sheds light on the lexical divergences in the construction of knowledge within the domains of psychology.

Introduction: Agricultural workplaces have a high number of incidents and fatalities, with the majority occurring from machinery use. Farmers' behaviour plays a critical role in maintaining safety, as improper or unsafe practices often lead to injuries and fatalities. This review categorises interventions targeting farm machine safety, examining both the behaviour change techniques (BCTs) used and their reported outcomes to understand how the techniques influence safety practices and outcomes on farms.
