New approach methodologies (NAMs) for the assessment of cleaning products for respiratory irritation: workshop report.

The use of new approach methodologies (NAMs) to assess respiratory irritation depends on several factors, including the specifics of exposure methods and cell/tissue-based test systems. This topic was examined in the context of human health risk assessment for cleaning products at a 1-day public workshop held on 2 March 2023, organized by the American Cleaning Institute (ACI). The goals of this workshop were to (1) review NAMs for evaluation of respiratory irritation, (2) examine different perspectives on current challenges and suggested solutions, and (3) publish a manuscript of the proceedings.

Self-extubation Laryngeal Injuries at an Academic Tertiary Care Center: A Retrospective Pilot Study.

Objectives: The purpose of this study is to identify laryngeal symptoms and injuries in self-extubated patients.

Methods: A retrospective chart review was conducted to identify symptoms and clinical findings associated with self-extubation. A novel scoring system was developed and used to quantify these findings.

Current and Future Issues in the Development of Spinal Agents for the Management of Pain.

Targeting analgesic drugs for spinal delivery reflects the fact that while the conscious experience of pain is mediated supraspinally, input initiated by high intensity stimuli, tissue injury and/or nerve injury is encoded at the level of the spinal dorsal horn and this output informs the brain as to the peripheral environment. This encoding process is subject to strong upregulation resulting in hyperesthetic states and downregulation reducing the ongoing processing of nociceptive stimuli reversing the hyperesthesia and pain processing. The present review addresses the biology of spinal nociceptive processing as relevant to the effects of intrathecally-delivered drugs in altering pain processing following acute stimulation, tissue inflammation/injury and nerve injury.
