Prevalence, incidence, and complications of malnutrition in severely injured patients.

Background: Severely injured patients may suffer from acute disease-related or injury-related malnutrition involving a marked inflammatory response. This study investigated the prevalence and incidence of malnutrition and its relation with complications in severely injured patients admitted to the intensive care unit (ICU).

Methods: This observational prospective cohort study included severely injured patients (Injury Severity Score ≥ 16), admitted to the ICU of five level-1 trauma centers in the Netherlands and United States.

Developing an alternative medium for in-space biomanufacturing.

In-space biomanufacturing provides a sustainable solution to facilitate long-term, self-sufficient human habitation in extraterrestrial environments. However, its dependence on Earth-supplied feedstocks renders in-space biomanufacturing economically nonviable. Here, we develop a process termed alternative feedstock-driven in-situ biomanufacturing (AF-ISM) to alleviate dependence on Earth-based resupply of feedstocks.

Splenectomy versus angioembolization for severe splenic injuries in a national trauma registry: To save, or not to save, the spleen, that is the question.

Background: The use of angioembolization as a first approach for treating severe, blunt splenic injuries has increased recently, yet evidence showing its superiority to immediate splenectomy is lacking. We compared the prognosis of angioembolization versus splenectomy in patients presenting hemodynamically unstable with high-grade, image-confirmed, blunt splenic injuries in a nationally representative dataset.

Methods: We queried the 2017-2022 Trauma Quality Improvement Program database for adults with blunt splenic injury abbreviated injury scale = 4-5, with arrival systolic blood pressure <90 mm Hg, and treated with either angioembolization or splenectomy <6 hours of arrival after a computed tomography scan.

Cognitive impairment in the schizophrenia spectrum: exploring the relationships of the g-factor with sociodemography, psychopathology, neurodevelopment, and genetics.

Background: Cognitive impairment constitutes a prevailing issue in the schizophrenia spectrum, severely impacting patients' functional outcomes. A global cognitive score, sensitive to the stages of the spectrum, would benefit the exploration of potential factors involved in the cognitive decline.

Methods: First, we performed principal component analysis on cognitive scores from 768 individuals across the schizophrenia spectrum, including first-degree relatives of patients, individuals at ultra-high risk, who had a first-episode psychosis, and chronic schizophrenia patients, alongside 124 healthy controls.
