Background: Accurate diagnosis of pulmonary embolism (PE) using contrast enhanced MRA (CE-MRA) requires awareness of both the direct and indirect findings of PE.
Purpose: To evaluate reader agreement of the direct and indirect findings of PE on CE-MRA.
Methods: We evaluated pulmonary artery diameter, right ventricle/left ventricle ratio, and clot/vessel lumen signal intensity ratio. Also, eight direct and eight indirect findings of PE were interpreted twice by two radiologists with different experience levels. The prevalence, and intra- and inter-reader agreement for the direct and indirect findings of PE were recorded. Statistical analysis of the measurements was assessed using intraclass correlation while Cohen's kappa test determined inter- and intra-reader agreement.
Results: We reviewed 66 positive CE-MRA exams, 10 of which cases were used for training. The largest PE for each of the remaining 56 cases (40 woman) were included in this analysis (38.9 ± 19.7 (mean age (years) ± S.D.)). The highest interobserver agreement for the direct findings were vessel cutoff (κ = 0.52, 95 % CI = (0.30, 0.74), p < .0001) and bright clot (κ = 0.51, 95 % CI = (0.26, 0.78), p = .0001). The highest interobserver agreement for the indirect findings were for atelectasis (κ = 0.67, 95 % CI = (0.49, 0.87), p < .0001), pleural effusions (κ = 0.56, 95 % CI = (0.32, 0.79), p = 0001) and blank slate sing (κ = 0.56, 95 % CI = (0.18, 0.94), p < .0001).
Conclusion: The indirect findings of atelectasis and pleural effusion had better interobserver reproducibility than the direct findings of vessel cutoff and bright clot. The intraobserver reproducibility of the direct and indirect findings is dependent on experience level.
Summary Statement: Using contrast enhanced magnetic resonance angiography for the diagnosis of pulmonary embolism, the indirect findings of atelectasis and pleural effusion had better interobserver reproducibility than the direct findings of vessel cutoff and bright clot.

The Gut in Critical Illness.

Purpose Of Review: The purpose of this narrative review is to describe the mechanisms for gut dysfunction during critical illness, outline hypotheses of gut-derived inflammation, and identify nutrition and non-nutritional therapies that have direct and indirect effects on preserving both epithelial barrier function and gut microbiota during critical illness.
Recent Findings: Clinical and animal model studies have demonstrated that critical illness pathophysiology and interventions breach epithelial barrier function and convert a normally commensal gut microbiome into a pathobiome. As a result, the gut has been postulated to be the "motor" of critical illness and numerous hypotheses have been put forward to explain how it contributes to systemic inflammation and drives multiple organ failure.
The Effect of Executive Function on Word Recognition: Comparison Between Native Chinese and Learners with Chinese as A Second Language (CSL).

Word recognition is a fundamental reading skill that relies on various linguistic and cognitive abilities. While executive functions (EF) have gained attention for their importance in developing literacy skills, their interaction with domain-specific skills in facilitating reading among different learner groups remains understudied. This study examines the relationship between EF, orthographic awareness, morphological awareness, and Chinese word recognition in 204 Chinese as a second language (CSL) students and 419 native Chinese primary students.

This study expanded on the existing literature by examining the unique associations between maternal religious socialization, as a form of cultural socialization, along with civic socialization practices, and Muslim American emerging adults' civic engagement. In addition, the mediating role of Muslim American emerging adults' religious identity in the association between maternal socialization practices and their civic attitudes and behaviors were assessed. Participants included 329 self-identified Muslim American emerging adults (Mage = 21.

Background: Although the number of studies reporting war-induced effects on the health of the Ukrainian population has been growing, there are still little data on assessing patients with type 2 diabetes (T2D) during the war. This study aimed to evaluate the impact of war on T2D patients' health to define key risk factors promoting disease progression.
Methods: A survey covering various aspects of T2D patients' experience and glycemic control data was conducted from June 2022 to February 2024.

Objective: To determine the financial impact of Ehlers-Danlos syndromes (EDS) on patients in the United States by examining the medical expenses incurred by patients.
Patients And Methods: We used a convenience sample approach and disseminated a self-reported survey questionnaire to individuals with EDS via patient advocacy organizations and support groups across the country, social media, and health professionals from April 1, 2023, to December 31, 2023. The survey focused on the out-of-pocket medical expenses incurred by patients.
