Evaluating general practitioners' focused lung ultrasound competence and findings in patients with suspected community-acquired pneumonia in general practice.

Objectives: To evaluate general practitioners' (GPs') ability to perform focused lung ultrasound (FLUS) following a training program and assess FLUS feasibility in general practice. Also, to describe FLUS findings and evaluate GPs' ability to interpret these in adults with acute lower respiratory tract infection (LRTI) when pneumonia is suspected and assess GPs' perception of FLUS impact.

Methods: Nine GPs, using point-of-care ultrasound, completed a FLUS training program.

Opportunities and Challenges of Chatbots in Ophthalmology: A Narrative Review.

Artificial intelligence (AI) is becoming increasingly influential in ophthalmology, particularly through advancements in machine learning, deep learning, robotics, neural networks, and natural language processing (NLP). Among these, NLP-based chatbots are the most readily accessible and are driven by AI-based large language models (LLMs). These chatbots have facilitated new research avenues and have gained traction in both clinical and surgical applications in ophthalmology.

The biarylitides: understanding the structure and biosynthesis of a fascinating class of Cytochrome P450 modified RiPP natural products.

The biarylitides are a recently discovered class of RiPP natural products that are fascinating both from the small size of the core peptides as well as the diversity of peptide crosslinking exhibited by the cytochrome P450 enzymes found in these systems. In this review, we address the discovery and biosynthetic diversity of these systems and discuss the methods and challenges of analysing the structures of these constrained cyclic peptides. We also discuss the structures of the P450 enzymes involved in these pathways and address the potential for alternate catalytic outcomes and activities as seen most recently with the inclusion of biarylitide related enzymes within rufomycin biosynthesis.

Does lifting female piglets by one hind leg increase the risk of umbilical and hind leg lesions?

Background: Umbilical lesions in pigs have a negative impact on animal welfare and productivity. It has been suggested that lifting young piglets by one hind leg may be a risk factor for developing omphalitis and umbilical hernia. However, the hypothesis that lifting piglets by one hind leg should stretch the umbilical wall and impede the healing of the umbilicus has not yet been investigated.

Development and psychometric evaluation of an instrument measuring ambulance nurses' adherence and attitudes to acute chest pain guidelines.

Background: Effective prehospital care for acute chest pain critically relies on ambulance nurses' adherence to clinical guidelines. However, current adherence is inadequate, with no instruments available to improve the situation. Therefore, this study aimed to develop and psychometrically evaluate an instrument measuring ambulance nurses' adherence to and attitudes towards acute chest pain guidelines, and to adapt and test the Attitudes Regarding Practice Guidelines instrument for measuring general attitudes towards guidelines.
