TiMON: a real-time integrated monitor for improving the placement and wear of emergency tourniquets.

Background: The use of emergency tourniquets among military personnel has helped to dramatically reduce battlefield deaths and has recently gained popularity in the civilian sector. Yet, even well-trained individuals can find it difficult to assess proper tourniquet application. Emergency tourniquets are typically deemed sufficiently tightened through cursory visual confirmation or pulse assessment.

Division of Pediatric Critical Care Medicine, Baylor College of Medicine, Texas Children's Hospital, Houston, TX, USA.
Objectives: Competency in diagnostic reasoning is integral to medical training and patient safety. Situativity theory highlights the importance of contextual factors on learning and performance, such as being informed of a provisional diagnosis prior to a patient encounter. This study aims to determine how being informed of a provisional diagnosis affects an intern's approach to diagnostic reasoning.

Article Synopsis
- The study explored the use of electrical impedance tomography (EIT) to evaluate the impact of thoracic epidural blockade (TEB) combined with general anesthesia on lung function during one-lung ventilation (OLV) in patients undergoing thoracic surgery.
- Thirty patients were randomly assigned to either a control group or a TEB group, where EIT measurements and blood gas analysis were performed to assess pulmonary perfusion distribution and ventilation-perfusion (V/Q) matching at different stages of the procedure.
- Results indicated that TEB significantly decreased mean arterial pressure and worsened arterial oxygen levels and shunt percentages during OLV, suggesting it adversely affected respiratory function in these patients.
Real-time ultrasound elastography in the diagnosis of newly identified thyroid nodules in adults: the ElaTION RCT.
Health Technol Assess
August 2024
Birmingham Clinical Trials Unit, University of Birmingham, Birmingham, UK.
Background: Strain and shear wave elastography which is commonly used with concurrent real-time imaging known as real-time ultrasound shear/strain wave elastography is a new diagnostic technique that has been reported to be useful in the diagnosis of nodules in several organs. There is conflicting evidence regarding its benefit over ultrasound-guided fine-needle aspiration cytology alone in thyroid nodules.
Objectives: To determine if ultrasound strain and shear wave elastography in conjunction with fine-needle aspiration cytology will reduce the number of patients who have a non-diagnostic first fine-needle aspiration cytology results as compared to conventional ultrasound-only guided fine-needle aspiration cytology.
Clinical consequences of computer-aided colorectal polyp detection.
Gut
November 2024
Gastroenterology and Hepatology, UZ Leuven, Leuven, Belgium.
Background And Aim: Randomised trials show improved polyp detection with computer-aided detection (CADe), mostly of small lesions. However, operator and selection bias may affect CADe's true benefit. Clinical outcomes of increased detection have not yet been fully elucidated.
