Critically ill patients often suffer from a complex and severe immunological dysfunction. The differentiation and function of human immune cells are fundamentally controlled through metabolic processes. New concepts of immunonutrition therefore try to use enteral and parenteral nutrition to positively impact on the immune function of intensive care unit patients. This review article concisely presents the currently available evidence on the commonly used isolated supplements (anti-oxidative substances, amino acids, essential fatty acids) and difficulties related to their clinical use. The second part presents new and more comprehensive concepts of immunonutrition to influence the intestinal microbiome and to modulate the macronutrient composition. Immunonutrition of critically ill patients bears enormous potential and could become a valuable clinical tool for modulation of the immunometabolism of intensive care unit patients.

Introduction: Sepsis is a leading cause of morbidity and mortality in neonatal foals. Administration of appropriate antimicrobials and early aggressive supportive treatment is central to the efficacious treatment of neonatal sepsis and has proven to positively influence outcomes. The primary aim of our study was to evaluate microorganism results and antimicrobial sensitivities of neonatal foals with a positive blood culture submitted to our intensive care unit (ICU) during 2005-2022.

These guidelines aim to improve the practices of fluid therapy by adopting a global perspective that considers both clinical efficacy and resource utilization in diverse healthcare settings. The guidelines address three key questions: (1) albumin versus crystalloids, (2) balanced crystalloids versus isotonic saline, and (3) small-volume hypertonic solutions versus isotonic crystalloids.

Objective: To evaluate the accuracy of the defining characteristics of the nursing diagnosis Impaired skin integrity (00046) in patients admitted to intensive care units (ICUs).
Methods: A cross-sectional diagnostic accuracy study was conducted with 105 adult patients admitted to an ICU. A latent class model with random effects was used to test the sensitivity and specificity of the defining characteristics investigated.

Introduction: Invasive pulmonary aspergillosis (IPA) increases the risk of mortality of critically ill patients. Diagnostic criteria specifically targeting patients in intensive care units(ICUs) have been developed to improve diagnostic sensitivity. This study investigated health outcomes among patients in ICUs with Aspergillus isolates identified using bronchoscopy.

Background: Extracorporeal membrane oxygenation (ECMO) has been proven to be a support method and technology for patients with cardiopulmonary failure. However, the transport of patients under ECMO support is challenging given the high-risk technical maneuvers and patient-care concerns involved. Herein, we examined the safety of ECMO during the transport of critically ill patients and its impact on mortality rates, to provide more secure and effective transport strategies in clinical practice.
