Chest computed tomography (CT) is essential for diagnosing and monitoring thoracic aortic dilations and aneurysms, conditions that place patients at risk of complications such as aortic dissection and rupture. However, aortic measurements in chest CT radiology reports are often embedded in free-text formats, limiting their accessibility for clinical care, quality improvement and research purposes. In this study, we developed a multi-method pipeline to extract structured aortic measurements from radiology reports, and compared the performance of fine-tuned BERT-based models with instruction-tuned Llama large language models (LLMs).

Whispering-gallery mode (WGM) resonators, renowned for their high Q-factors and narrow line widths, are widely utilized in integrated photonics. Integrating diffraction gratings onto WGM cavities has gained significant attention because these gratings function as azimuthal refractive index modulators, enabling single-mode WGM emissions and supporting beams with orbital angular momentum (OAM). The introduction of curved grating structures facilitates guided mode resonances by coupling high-order diffracted waves with leaking modes from the waveguide.

Healthcare workers continue to experience high levels of work-related stress which continue to negatively affect their psychological, physical, and emotional well-being. This is even more prevalent among healthcare workers who work in surgical specialities, with the surgical operation room becoming a known stressor at hospitals. This study aims to assess work-related stress among surgical team members at Ahmadu Bello University Teaching Hospital in Zaria between January 2021-2022.

Acute intermittent porphyria (AIP), one of the most severe types of acute hepatic porphyria, is an autosomal dominant inherited disorder of heme biosynthesis. We present a case of a 16-year-old girl who presented with severe abdominal pain, subjected to a laparotomy and later developed seizures and other neurological manifestations. Initial investigations showed hyponatraemia.
