AI Article Synopsis
- Trace elements are crucial for immune and antioxidant functions, especially in critically ill patients, but measuring their levels can be expensive.
- A study compared two methods of monitoring plasma concentrations of selenium, copper, and zinc in ICU patients: computer reminders in 2006 and nutritionist-guided samplings in 2009.
- The results showed that the nutritionist-guided approach led to a significant reduction in lab tests and costs (by 55%), despite patients in 2009 having more severe illnesses, indicating more efficient use of resources.
Article Abstract
Background & Aims: Trace elements (TE) are involved in the immune and antioxidant defences which are of particular importance during critical illness. Determining plasma TE levels is costly. The present quality control study aimed at assessing the economic impact of a computer reminded blood sampling versus a risk guided on-demand monitoring of plasma concentrations of selenium, copper, and zinc.
Methods: Retrospective analysis of 2 cohorts of patients admitted during 6 months periods in 2006 and 2009 to the ICU of a University hospital.
Inclusion Criteria: to receive intravenous micronutrient supplements and/or to have a TE sampling during ICU stay. The TE samplings were triggered by computerized reminder in 2006 versus guided by nutritionists in 2009.
Results: During the 2 periods 636 patients met the inclusion criteria out of 2406 consecutive admissions, representing 29.7% and 24.9% respectively of the periods' admissions. The 2009 patients had higher SAPS2 scores (p = 0.02) and lower BMI compared to 2006 (p = 0.007). The number of laboratory determinations was drastically reduced in 2009, particularly during the first week, despite the higher severity of the cohort, resulting in à 55% cost reduction.
Conclusions: The monitoring of TE concentrations guided by a nutritionist resulted in a reduction of the sampling frequency, and targeting on the sickest high risk patients, requiring a nutritional prescription adaptation. This control leads to cost reduction compared to an automated sampling prescription.

Influenza accounts for 30% of the total morbidity and mortality in the European Union. However, the specific burden in different European countries is largely unknown, and more research is needed to ascertain the reality of this disease. In this retrospective study, we analyzed the burdens of hospitalization, intensive care unit (ICU) admission and in-hospital mortality in Spain over five seasons (2015-2020) via publicly available Minimum Basic Datasets (MDBS).

Generosity through donation plays a crucial role in reducing inequality and influencing human behavior. However, previous research on donation has overlooked individuals' acceptance of the extent of inequality, which acts as a trigger for donation. To address this gap, this paper systematically explores the impact of donation based on inequality tolerance on the evolution of cooperation in spatial public goods game.

The urgent calls for action on climate change underscore the importance of increasing sustainable behavior among individuals who have traditionally veered away from it, such as those on the political right. Utilizing data from four geopolitical regions across 24 countries, we explore whether vulnerability to natural disasters, brought on by either experiencing or anticipating a natural disaster, is a crucial factor. We find that as vulnerability to natural disasters increases, sustainable consumption intentions significantly increase among rightists in Western Europe, Israel, and the United States.

Phytophthora palmivora, an oomycete pathogen, induces leaf fall disease in rubber trees (Hevea brasiliensis), causing significant economic losses. Effective disease management requires an understanding metabolic dynamics during infection. This study employed untargeted metabolomic and proteomic analyses to investigate the response of rubber seedling leaves to P.
