Introduction: Fatigue is an acknowledged safety risk in diverse operational settings. As a result, there has been growing interest in developing and implementing activities to improve alertness, performance, and safety in real-world operations where fatigue is a factor.
Methods: A comprehensive Alertness Management Program (AMP) that included education, alertness strategies, scheduling, and healthy sleep was implemented in a commercial airline. An operational evaluation was conducted with 29 flight crewmembers, first when flying a standard schedule without AMP components (i.e., standard condition) compared with full AMP implementation, which included flying an innovative schedule that incorporated physiological sleep and alertness principles (i.e., intervention condition). The evaluation included objective measures of sleep quantity (actigraphy), psychomotor vigilance task (PVT) performance, and subjective reports of daily activities and sleep.
Results: The results showed that the 3.5-h educational CD improved pre-education test scores from an average 74% correct to a post-education average of 98%. Alertness strategies showed minimal changes, though the daily diary did not allow for refined evaluation of duration, frequency, and timing of use. The intervention condition was associated with significantly more sleep (1 h, 9 min; p < 0.01) during the trip period compared with the standard schedule. All performance metrics showed significantly better performance during the intervention condition trip schedule (p < 0.01) compared with the standard condition.
Discussion: This first-ever evaluation of a comprehensive AMP showed significantly improved knowledge, support for the use of alertness strategies, and increased sleep and performance during actual operations. The robust and consistent findings support the use of an AMP approach to effectively manage fatigue in operational settings.

Article Synopsis
- This study examines a rare complication of cerebral venous thrombosis (CVT) in patients with primary Sjögren's syndrome (pSS), discussing clinical features, treatment, and outcomes.
- A total of twelve patients were reviewed, predominantly middle-aged women, with common symptoms including headache and typical pSS manifestations such as dry mouth and arthritis.
- All patients received treatment including anticoagulants and recovered fully, highlighting the need for increased awareness and screening for autoimmune diseases in CVT cases, especially with unilateral transverse sinus involvement.

Optimizing an emergency air pollution control strategy for haze events presents a significant challenge due to the extensive computational demands required to quantify the complex nonlinearity associated with controls on diverse air pollutants and regional sources. In this study, we developed a forecasting tool for emergency air pollution control strategies based on a predictive response surface model that quantifies PM responses to emission changes from different pollutants and regions. This tool is equipped to assess the effectiveness of emergency control measures corresponding to various air pollution alerts and to formulate an optimized control strategy aimed at specific PM targets.

Pathogenic microorganisms can infect a variety of niches in the human body. During infection, microbes can only persist if they adapt adequately to the dynamic host environment and the stresses imposed by the immune system. While viruses entirely rely on host cells to replicate, bacteria and fungi use their pathogenicity mechanisms for the acquisition of essential nutrients that lie under host restriction.

Purpose: It is presumed by many that acute sleep loss results in degraded in-game esports (competitive, organized video game play) performance. However, this has not been experimentally investigated to date. The objective of the current experiment was to elucidate whether ~29hrs of total sleep deprivation impacts in-game performance for the popular esport
