Nutrition therapy for critically ill patients - Five key problems.
Clin Nutr
January 2025
Department of Intensive Care Medicine, University Medical Centre Hamburg-Eppendorf, Germany. Electronic address:
Background & Aims: A pragmatic trial and its secondary analyses have demonstrated that nutritional care not only reduces complications but also significantly improves survival in medical patients at risk of malnutrition. In contrast, for critically ill patients comparable evidence is scarce. Consequently, many propositions for refining the research agenda and study design in the field of critical care nutrition have already been made.

Osteopetrosis is a group of genetically and clinically diverse inherited disorders characterized by an increase in bone density. The main known cause is an abnormality in the development or function of osteoclasts. Hence, the process of bone resorption is impaired, resulting in: 1- a reduction in bone marrow volume and, subsequently, a decrement in the hematopoietic capacity of bone marrow, which leads to anemia and compromised immunological function; 2- improper bone development, which leads to pressure on peripheral nerves, causing auditory, visual, and movement impairments; and 3- disturbance in the formation of bone microstructure that leads to susceptibility to bone fracture.

The field of medicine is constantly changing and, as healthcare providers, we are fortunate to be practicing in a time when patients are living longer and novel therapeutic options continue to evolve. However, these new advances may be associated with adverse effects that practitioners need to be aware of. Some of these impair the immune system leading to secondary immunodeficiencies (SID) that increase host susceptibility to infections and other complications.

Department of Medical Biochemistry, Institute of Health, Dambi Dollo University, Dambi Dolo, Ethiopia.
Background: The pathomechanism of blast traumatic brain injury (TBI) and blunt TBI is different. In blast injury, evidence indicates that a single blast exposure can often manifest long-term neurological impairments. However, its pathomechanism is still elusive, and treatments have been symptomatic.
View Article and Find Full Text PDFThe polymerase gamma (POLG) gene mutation is associated with mitochondria and metabolism disorders, resulting in heterogeneous responses to immunological activation and posing challenges for mitochondrial disease therapy. Optical metabolic imaging captures the autofluorescent signal of two coenzymes, NADH and FAD, and offers a label-free approach to detect cellular metabolic phenotypes, track mitochondria morphology, and quantify metabolic heterogeneity. In this study, fluorescence lifetime imaging (FLIM) of NAD(P)H and FAD revealed that POLG mutator macrophages exhibit a decreased NAD(P)H lifetime, and optical redox ratio compared to the wild-type macrophages, indicating an increased dependence on glycolysis.
