A growing number of individuals with unmet mental health needs in the United States rely on emergency medical services during mental health crises, and 9-1-1 emergency medical dispatchers (EMD) are often a critical lifeline to help. Unfortunately, current industry-standard dispatching protocols and training required for EMD certification largely lack specificity for managing 9-1-1 calls related to mental health emergencies. The purpose of this report is to illustrate the value of additional targeted training for EMDs that enables them to more effectively assist callers struggling with mental illness or suicidal thoughts. ⋯ Key principles and phrasing from the training were used successfully by the EMD to dissuade the caller from self-harm, and he was ultimately safely met by first responders on scene and transported for care. We also share post-call recollections and reactions from the EMD to demonstrate how in addition to reducing risks for callers and their families, EMHD training has the potential to reduce on-scene risks for field responders and may increase confidence and mitigate negative stress responses in EMDs. Emergency medical services systems in the United States should continue to explore enhanced training and protocols to improve care for 9-1-1 callers experiencing mental health crises.

Observational Study
The pleural gradient does not reflect the superimposed pressure in patients with class III obesity.
The superimposed pressure is the primary determinant of the pleural pressure gradient. Obesity is associated with elevated end-expiratory esophageal pressure, regardless of lung disease severity, and the superimposed pressure might not be the only determinant of the pleural pressure gradient. The study aims to measure partitioned respiratory mechanics and superimposed pressure in a cohort of patients admitted to the ICU with and without class III obesity (BMI ≥ 40 kg/m2), and to quantify the amount of thoracic adipose tissue and muscle through advanced imaging techniques. ⋯ In patients with class III obesity, the superimposed pressure does not approximate the pleural pressure gradient, which is higher than in patients with lower BMI. The quantity and distribution of subcutaneous and intrathoracic adiposity also contribute to increased pleural pressure gradients in individuals with BMI ≥ 40. This study introduces a novel physiological concept that provides a solid rationale for tailoring mechanical ventilation in patients with high BMI, where specific guidelines recommendations are lacking.

Traumatic spinal injuries (TSI) pose a significant life-long burden, impacting both military and civilian populations. Assessing long-term outcomes is crucial for comprehending the enduring consequences of the initial insult and informing effective prevention and management strategies. Most existing studies have narrowly focused on subsets of traumatic cord injuries, leaving a gap in understanding the broader impact of severe spinal trauma. This study aims to examine severe TSIs in military personnel, who may face unique risk factors and injury patterns, and its association with long-term disability. ⋯ Upon long-term follow-up, military personnel with severe TSI exhibit a significantly higher prevalence of debilitating disability compared to those with significant non-spinal traumatic injuries. These findings highlight the critical need for targeted prevention strategies and improved management of spinal injuries to reduce long-term disability. Strengths of this study include its extensive follow-up period and the use of multiple nationwide registries. However, the study may be limited by potential discrepancies in identity matching across databases and the reliance on disability claims, which may underrepresent the true prevalence of long-term disability. Future research should explore the efficacy of early interventions and rehabilitation strategies in mitigating long-term disability following spinal injuries. This study underscores the importance of developing evidence-based policies to enhance care for individuals with TSIs.

Too high or too low patient volumes and work amounts may overwhelm health care professionals and obstruct processes or lead to inadequate personnel routine and process flow. We sought to evaluate, whether an association between current caseload, current workload, and outcomes exists in intensive care units (ICU). ⋯ In a system with comparably high intensive care resources and mandatory staffing levels, patients' survival chances are generally not affected by high intensive care unit caseload and workload. However, extraordinary circumstances, such as the COVID-19 pandemic, may lead to higher risk of death, if planned capacities are exceeded. High workload in ICUs in smaller hospitals with lower staffing levels may be associated with increased risk of death.
