The National Emergency X-Radiography Utilization Study (NEXUS) criteria were derived from a heterogeneous group of adult blunt trauma patients, with the outcome measure assessed most commonly using plain X-ray radiographs. Recent observations have suggested inadequacy of these criteria for excluding injury in population subgroups such as the elderly. The aim of this systematic review was to determine the sensitivity of the NEXUS criteria in excluding cervical spine injury among older patients aged ≥65 years. A systematic review of the literature published prior to 1 January 2017 that reported on the performance of the NEXUS criteria among older patients was conducted. The databases OVID Embase and OVID Medline were searched. The sensitivity of the NEXUS criteria was recalculated for each study among older patients. There were seven studies included in this review. All studies were considered to be at risk of bias and rated down for quality of evidence. Emergency physicians were assessors in all included studies. Sensitivity of the NEXUS criteria among older patients ranged from 66% to 100%. Variable sensitivity was demonstrated when the NEXUS criteria were applied to older blunt trauma patients. This questions the applicability of the NEXUS criteria in this subgroup.

A psychometric approach to decision-making thresholds across legal and societal domains.
PNAS Nexus

Department of Psychology, Vanderbilt University, Nashville, TN 37240, USA.
What constitutes enough evidence to make a decision? While this is an important question across multiple domains, it takes on special importance in the US legal system, where jurors and judges are instructed to apply specific burdens of proof to render life-changing decisions. Civil trials use a preponderance of evidence (PoE) threshold to establish liability, while criminal trials require proof beyond a reasonable doubt (BaRD) to convict. It is still unclear, however, how laypeople interpret and apply these decision thresholds and how these standards compare to people's intuitive belief (IB) of what constitutes enough evidence.

Specialist weight management services including bariatric surgery are commissioned within regions of England called Integrated Care Systems (ICSs) with eligibility and treatment guidelines determined as part of the National Institute for Health and Care Excellence (NICE) guidance. Reported variation in commissioning and bariatric surgery eligibility criteria has not been previously mapped. Freedom of Information (FOI) requests provide a tool, supported by legislation, to ask questions of public authorities including ICSs such that they must respond accurately.

Background: Drowning is a leading cause of death among young children. The United Nations Resolution on global drowning prevention (2021) and World Health Assembly Resolution in 2023 have drawn attention to the issue. This scoping review synthesizes the current evidence on the effectiveness of child drowning prevention interventions since the 2008 World Report on Child Injury Prevention and implications for their implementation.

Cervical spine injuries are one of the most common injuries of the spine that are encountered in the emergency department (ED). More than half of all spinal injuries presenting to the ED involve the cervical spine, with nearly half of them resulting from road traffic accidents. The majority of spinal cord injuries are found to occur in males of younger age groups, with almost half of them resulting in incomplete spinal cord injuries.
