Available data on radiologists' missed cervical spine fractures are based primarily on studies using human reviewers to identify errors on re-evaluation; such studies do not capture the full extent of missed fractures. To use machine-learning (ML) models to identify cervical spine fractures on CT missed by interpreting radiologists, characterize the nature of these fractures, and assess their clinical significance. This retrospective study included all cervical spine CT examinations performed in adult patients in the emergency department between January 1, 2018 and December 31, 2022.

Article Synopsis
  • Traditional pain studies have focused on single pain scores, which don't fully capture the complex effects of chronic pain on a person's daily life, mood, and overall quality of life.
  • The study evaluated the Nalu™ Neurostimulation System for treating low-back and leg pain through a 90-day follow-up of patients implanted with this device at 15 pain centers in the US.
  • Results showed that 94% of participants achieved meaningful improvements in at least two patient-reported outcomes, indicating the system's effectiveness in managing chronic pain.

Article Synopsis
  • Five non-pregnant sows were studied to measure their energy expenditure through heat production while being fed different amounts of energy.
  • When fed at the maintenance energy requirement (1.0 ME), sows lost weight due to higher heat production than energy intake, whereas feeding them double the requirement (2.0 ME) resulted in weight gain and higher heat production.
  • The study suggests a recalibrated maintenance energy requirement of 506 kJ ME/kg for modern non-pregnant sows based on their energy consumption and expenditure observations.

Article Synopsis
  • The highlights cover research from 2022 divided into three sections: preoperative, intraoperative, and postoperative, focusing on advancements in heart transplantation.
  • The preoperative section discusses candidate assessment, donor optimization, and factors like cannabis use and comorbidities that impact transplantation success.
  • The intraoperative section emphasizes teamwork and surgical techniques while the postoperative section highlights managing complications like tricuspid regurgitation and exploring xenotransplantation options.

Purpose To evaluate the performance of the winning machine learning (ML) models from the 2023 RSNA Abdominal Trauma Detection Artificial Intelligence Challenge. Materials and Methods The competition was hosted on Kaggle and took place between July 26, 2023, to October 15, 2023. The multicenter competition dataset consisted of 4,274 abdominal trauma CT scans in which solid organs (liver, spleen and kidneys) were annotated as healthy, low-grade or high-grade injury.
