Article Abstract
This study investigated changes in utilization of diagnostic imaging-computed tomography (CT) angiography and magnetic resonance (MR) angiography-and treatments-stent placement, angioplasty, atherectomy, and bypass-in peripheral arterial disease (PAD) across different physician specialties and healthcare facilities from 2011 to 2021. Data were gathered from the 2011-2021 Physician/Supplier Procedure Summary files and tallied per 100,000 Medicare beneficiaries. Sites of service included inpatients, physician offices, and hospital outpatient departments. Physician specialties included interventional radiologists, interventional cardiologists, and vascular surgeons. From 2011 to 2021 and per 100,000 Medicare beneficiaries, CT angiography utilization rates grew (+14%), vascular ultrasound (US) utilization rates decreased (-17%), and MR angiography utilization rates decreased (-86%). Per 100,000, atherectomy utilization rates increased by 159% (from 37.7 to 55.1), and bypass grafting utilization rates decreased by 74% (from 40.7 to 10.5). Combined angioplasty, stent placement, stent placement with atherectomy, and atherectomy utilization rates increased (+16%), particularly in the office (angioplasty, +277%; atherectomy, +1036%). These data support that PAD management shifted toward endovascular procedures in office-based laboratories.

Background: There is conflicting literature regarding mortality outcomes associated with REBOA usage in patients with severe thoracic or abdominal trauma. Our study aims to assess the benefits and negative implications of REBOA use in adult trauma patients in hemorrhagic shock with severe thoracic or abdominal injuries.
Methods: This retrospective cohort analysis utilized the American College of Surgeons Trauma Quality Improvement Program Participant Use File (ACS-TQIP-PUF) database from 2017 to 2023 to evaluate adult patients with severe isolated thoracic or abdominal trauma undergoing REBOA placement.

Background: Neutropenia is a common laboratory finding in children, therefore it is a common referral reason to pediatric hematology units. This study hypothesizes that most neutropenic children do not require pediatric hematology consultation, and that key clinical indicators can guide the need for referral.
Methods: Medical records of 180 patients who were admitted to a tertiary reference center, were evaluated in terms of demographical data, physical examination findings, laboratory findings, and outcome measures.

Three new steroidal saponins, kingianoside L-N (1-3), whose structures were elucidated through comprehensive spectroscopic analysis, and 15 known compounds (4-18) were isolated from Polygonatum kingianum var. grandifolium, a source of the traditional antihyperglycemic medicine Polygonati rhizome. The effects of compounds 1-13 on α-glucosidase activity were evaluated in vitro.

The persistent threat posed by phytopathogenic fungi to agricultural systems underscores the critical need for novel fungicides. Here, we synthesized and characterized a series of novel acridospiroisoxazole derivatives (H1-H36) using H/C NMR and mass spectrometry. The absolute configuration of compound H23 was confirmed using single-crystal x-ray diffraction analysis.

Importance: Sepsis remains a leading cause of death in infectious cases. The heterogeneity of immune responses is a major challenge in the management and prognostication of patients with sepsis. Identifying distinct immune response subphenotypes using parsimonious classifiers may improve outcome prediction, particularly in resource-limited settings.
