Acute Mild Hypoxic Hypoxia Effects on Cognitive and Simulated Aircraft Pilot Performance.
The effects of acute mild hypoxic hypoxia (HH) and physical activity on physiological measures, signs and symptoms, mood, fatigue, cognition, and performance on a simulated flight task were investigated between 8000 (8K; 2438 m) and 14,000 ft (14K; 4267 m). ⋯ Our findings indicate a significant influence of mild HH on a number of outcome measures at altitudes above 10K, where operational restrictions are well established. In contrast, there was no clear influence of HH on performance at lower altitudes (i.e., 8K and 10K). The occurrence of HH symptoms and the decrements in target identification latency and accuracy at 8K and 10K may negatively impact flight performance and require further study.Bouak F, Vartanian O, Hofer K, Cheung B.

Evidence supports the efficacy of incorporating select recognized aviation practices and procedures into healthcare. Incident analysis, debrief, safety brief, and crew resource management (CRM) have all been assessed for implementation within the UK healthcare system, a world leader in aviation-based patient safety initiatives. Mindful application, in which aviation practices are specifically tailored to the unique healthcare setting, show promise in terms of acceptance and long-term sustainment. ⋯ Aviation modeled incident analysis, debrief, safety brief, and CRM training are increasingly undertaken within the UK healthcare system. Nuanced application, in which the unique aspects of the healthcare setting are addressed as part of a comprehensive safety approach, shows promise for long-term success. The patient safety brief and aviation modeled incident analysis are in earlier phases of implementation, and warrant further analysis.Powell-Dunford N, Brennan PA, Peerally MF, Kapur N, Hynes JM, Hodkinson PD.

Dysrhythmias in Laypersons During Centrifuge-Simulated Suborbital Spaceflight.
There are limited data on cardiac dysrhythmias in laypersons during hypergravity exposure. We report layperson electrocardiograph (ECG) findings and tolerance of dysrhythmias during centrifuge-simulated suborbital spaceflight. ⋯ Dysrhythmias in laypersons undergoing simulated suborbital spaceflight were well tolerated, though RB was frequently noted during short-duration +Gx exposure. No subjects demonstrated associated symptoms or objective hemodynamic sequelae from these events. Even so, heightened caution remains warranted when monitoring dysrhythmias in laypersons with significant cardiopulmonary disease or taking medications that modulate cardiac conduction.Suresh R, Blue RS, Mathers CH, Castleberry TL, Vanderploeg JM.

Protective Effects of Emotional Intelligence and Proactive Coping on Civil Pilots' Mental Health.
Pilots' mental health is an issue of crucial importance that may endanger flight safety. As such, it is of profound significance to address the question of what characteristics are protective of mental health among pilots. The present study aimed to explore the indirect effects of emotional intelligence (EI) on depression and anxiety via proactive coping, and examine the moderating role of previous flight experience (PFE) in the conditional indirect effect of EI on depression through proactive coping. ⋯ The results showed that EI and proactive coping had protective potential in the prevention of depression and anxiety. Implications for the promotion of mental health and diminishing depression and anxiety among pilots are discussed.Guo Y, Ji M, You X, Huang J.
