AI Article Synopsis
Article Abstract
A 6-month prospective cohort study was performed in patients with or without dementia admitted to two Korean long-term care (LTC) facilities. Participants were categorized into four groups: (a) no delirium or dementia, (b) dementia only, (c) delirium only, and (d) delirium superimposed on dementia (DSD). Delirium incidence, mortality, readmission, discharge placement, length of stay, and other associated factors were evaluated. The incidence of delirium was 48%. The largest number of patients belonged to the DSD group; outcomes associated with delirium were analyzed as covariates. The delirium-only group had a significantly higher mortality rate than other groups. Length of stay was the longest for the dementia-only group. On the Kaplan-Meier survival curve, the delirium-only group had the lowest probability of survival compared to other groups. The mortality rate of patients with delirium only was significantly higher than the mortality rates of all other groups. LTC facilities should provide preventive interventions for patients with delirium. [Journal of Gerontological Nursing, 44(9), 41-50.].

Ten Machine Learning Models for Predicting Preoperative and Postoperative Coagulopathy in Patients With Trauma: Multicenter Cohort Study.

Background: Recent research has revealed the potential value of machine learning (ML) models in improving prognostic prediction for patients with trauma. ML can enhance predictions and identify which factors contribute the most to posttraumatic mortality. However, no studies have explored the risk factors, complications, and risk prediction of preoperative and postoperative traumatic coagulopathy (PPTIC) in patients with trauma.

Background: An aging population in combination with more gentle and less stressful surgical procedures leads to an increased number of operations on older patients. This collectively raises novel challenges due to higher age heavily impacting treatment. A major problem, emerging in up to 50% of cases, is perioperative delirium.

Purpose: We performed a systematic review with meta-analysis examining the relationship between pain or pain medications and delirium occurence, duration, and severity.
Methods: We searched MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials from inception to May 15, 2023. We included randomised or observational studies among critically ill adults, that reported data on pain or exposure to analgesics, and reported delirium presence, duration, or severity with no language or region restrictions.

Background: Chronic neurologic deficits from traumatic brain injury (TBI) and subsequent infectious encephalitis are poorly characterized.
Methods: Using TriNetX database we queried patients 18 years or older with a confirmed diagnosis of encephalitis between 2016 and 2024. Patient cohorts included those with a diagnosis of TBI at least one month before encephalitis ( = 1,038), those with a diagnosis of a TBI anytime before encephalitis ( = 1,886), and those with encephalitis but no TBI, ( = 45,210; = 45,215).

Delirium is a highly prevalent neuropsychiatric syndrome characterised by acute and fluctuating impairments in attention and cognition. Mechanisms driving delirium are poorly understood but it has been suggested that blood cytokines and chemokines cross the blood brain barrier during delirium, directly impairing brain function. It is not known whether these molecules reach higher brain levels when the blood cerebrospinal fluid barrier (BCSFB) is impaired.
