Aim: This meta-analysis evaluates the diagnostic accuracy of ultrasound (US) for bone fractures over the past 47 years, comparing it to established imaging standards.

Material And Methods: We adhered to PRISMA 2020 guidelines to search Medline, EMBASE, and the Cochrane Library using tailored search strategies. The primary outcome, US diagnostic performance, was analyzed across various subgroups including clinical relevance, patient age, and anatomical considerations.

Point-of-care ultrasound (PoCUS) has become an indispensable standard in emergency medicine. Emergency medicine ultrasound (EMUS) is the application of bedside PoCUS by the attending emergency physician to assist in the diagnosis and management of many time-sensitive health emergencies. In many ways, using PoCUS is not only the mere application of technology, but also a fusion of already existing examiner skills and technology in the context of a patient encounter.

Stable single metal adatoms on oxide surfaces are of great interest for future applications in the field of catalysis. We studied iridium single atoms (Ir) supported on a FeO(001) single crystal, a model system previously only studied in ultra-high vacuum, to explore their behavior upon exposure to several gases in the millibar range (up to 20 mbar) utilizing ambient-pressure X-ray photoelectron spectroscopy. The Ir single adatoms appear stable upon exposure to a variety of common gases at room temperature, including oxygen (O), hydrogen (H), nitrogen (N), carbon monoxide (CO), argon (Ar), and water vapor.

Article Synopsis
  • The study investigates the link between thrombin generation and the recurrence of venous thromboembolism (VTE), major bleeding, and mortality in elderly patients (aged 65 and older) with acute VTE.
  • Researchers followed 551 patients for 2 years, assessing thrombin generation one year after initial VTE treatment, with the primary focus on outcomes like VTE recurrence, major bleeding, and mortality.
  • The findings indicate that while thrombin generation can help predict VTE recurrence in non-anticoagulated elderly patients, it does not correlate with major bleeding or mortality, suggesting its potential use in identifying high-risk individuals for VTE recurrence.

Sepsis and septic shock are life-threatening emergencies associated with increased morbidity and mortality. Hence, early diagnosis and management of both conditions is of paramount importance. Point-of-care ultrasound (POCUS) is a cost-effective and safe imaging modality performed at the bedside, which has rapidly emerged as an excellent multimodal tool and has been gradually incorporated as an adjunct to physical examination in order to facilitate evaluation, diagnosis and management.
