Exploring the Impact of ICU Diary on ICU Survivors' Emotions and Feelings: A Qualitative Study.

Background: An intensive care unit (ICU) diary provides a powerful and moving account of a patient's journey through critical care.

Aim: The primary goal of this research was to explore the qualitative perceptions of general ICU survivors toward the ICU diary, which was completed during their hospital stay and reintroduced to them during a follow-up visit 6 months after ICU discharge.

Setting: An Italian general ICU with structured follow-up and an ICU diary program.

Residual flow of the radial artery in the presence of an arterial catheter: A single-centre retrospective observational study.

Background: Arterial catheterisation is a common procedure used to manage critically ill patients. The radial artery, both for its favourable anatomical position and the presence of ulnar collateral circulation, is the most used. While there is a consensus for a catheter/vein ratio of ⩽33% for venous catheterisation, there are no strong indications for arterial catheterisation.

Unraveling the Anti-Aging Properties of Phycocyanin from the Cyanobacterium Spirulina ().

In recent years, marine natural products have become one of the most important resources of novel lead compounds for critical diseases associated with age. , a dietary supplement made from blue-green algae (cyanobacteria: scientific name ), is particularly rich in phycocyanin, a phycobiliprotein, which accounts for up to 20% of this cyanobacterium's dry weight and is considered responsible for its anti-cancer, anti-inflammatory and antioxidant activities. Although the anti-aging activity of phycocyanin has been investigated, how exactly this compound works against aging remains elusive.

Analysis of Petrogenic Hydrocarbons in Plant Tissues: A Simple GC-MS-Based Protocol to Distinguish Biogenic Hydrocarbons from Diesel-Derived Compounds.

Diesel contamination of farming soils is of great concern because hydrocarbons are toxic to all forms of life and can potentially enter the food web through crops or plants used for remediation. Data on plant ability to uptake, translocate and accumulate diesel-derived compounds are controversial not only due to the probable diverse attitude of plant species but also because of the lack of a reliable method with which to distinguish petrogenic from biogenic compounds in plant tissues. The purpose of this study was to set up a GC-MS-based protocol enabling the determination of diesel-derived hydrocarbons in plants grown in contaminated soil for assessing human and ecological risks, predicting phytoremediation effectiveness and biomass disposal.
