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.

Impact of minimal self disorders on naturalistic episodic memory in first-episode psychosis and parallels in healthy individuals with schizotypal traits.

Background: Self-disorders constitute a core feature of the schizophrenia spectrum, including early stages such as first-episode psychosis (FEP). These disorders impact the minimal Self, or bodily self-consciousness, which refers to the basic, pre-reflective sense of embodied experience. The minimal Self is intrinsically linked to episodic memory, which captures specific past experiences of the Self.

Use of parenteral nutrition in the management of enterocutaneous fistula.

Nutrition plays an integral role in the management of patients with enterocutaneous fistula (ECF), but practice guidelines are often vague because of limited evidence. As a result, clinicians must rely on expert consensus and sound nutrition principles to guide practice. The initial phase of ECF management involves recognition (eg, fistula location and quantifying output) and stabilization (eg, source control and fluid and electrolyte balance).
