Factors in Initial Anticoagulation Choice in Hospitalized Patients With Pulmonary Embolism.
JAMA Netw Open
January 2025
Department of Emergency Medicine, University of Massachusetts Chan Medical School-Baystate, Springfield.
Importance: Despite guideline recommendations to use low-molecular-weight heparins (LMWHs) or direct oral anticoagulants in the treatment of most patients with acute pulmonary embolism (PE), US-based studies have found increasing use of unfractionated heparin (UFH) in hospitalized patients.
Objective: To identify barriers and facilitators of guideline-concordant anticoagulation in patients hospitalized with acute PE.
Design, Setting, And Participants: This qualitative study conducted semistructured interviews from February 1 to June 3, 2024, that were recorded, transcribed, and analyzed in an iterative process using reflexive thematic analysis.
Optimizing Radiation Protection in PET/CT Examinations: Reducing Occupational Exposure During Patient Positioning.
Cureus
December 2024
Department of Emergency and Intensive Care Medicine, Hospital of the University of Occupational and Environmental Health, Fukuoka, JPN.
Objectives The objective of this study was to evaluate the occupational radiation exposure of healthcare workers during positron emission tomography (PET)/CT examinations, focusing on patient positioning and assessing the effectiveness of different radiation protection measures. Methods Thirteen medical workers (physicians, radiological technologists, and nurses) performed PET/CT examinations on 86 patients at a major Japanese hospital from June to August 2019. Occupational doses were measured using a real-time semiconductor dosimeter: RaySafe i2 (Unfors RaySafe, Billdal, Sweden), recording the 1 cm dose equivalent (Hp(10)).

Background And Purpose: Normal pressure hydrocephalus (NPH) is a diagnostic challenge because its clinical symptoms and imaging appearance resemble normal aging and other forms of dementia. Identifying NPH is essential so that patients can receive timely treatment to improve gait distortion and quality of life. An automated marker of NPH was developed and evaluated on clinical CT images, and its utility was assessed in a large patient cohort.

J Ultrasound Med
January 2025
Department of Radiology, Mayo Clinic Arizona, Phoenix, Arizona, USA.
Objectives: To combine sonographic Murphy sign (SMS) with clinical parameters to effectively stratify patients into risk groups for acute cholecystitis.
Methods: Consecutive emergency department patients from April 1, 2019 to August 31, 2022 with possible acute cholecystitis were grouped using patient age, sex, and white blood cell count to determine the rate of acute cholecystitis found in subgroups. Three distinct clinical risk groups were established and then regrouped by prospective assessment of SMS into three non-imaging risk groups.

Neuroendocrine tumors (NETs) are a diverse group of neoplasms whose prevalence is increasing globally, primarily due to advancements in diagnostic techniques. NETs arise from cells of the diffuse endocrine system and can occur in various locations, with the gastrointestinal tract being the most common. Their diverse clinical presentations, which range from asymptomatic to severe hormone-induced syndromes, pose significant diagnostic challenges.
