Comprehensive profiling of phthalic acid esters (PAEs) in air-conditioning filters from diverse indoor environments across 12 major cities in China.

Phthalic acid esters (PAEs), commonly used as plasticizers, primarily through airborne exposure. Unlike settling dust, air conditioning filters can effectively capture suspended particles and are an important source of indoor pollutants. This study analyzed 94 air-conditioning filter samples collected from five room types: bedrooms, living rooms, kitchens, mahjong rooms, and cloakrooms, across summer, autumn, and winter in 12 major Chinese cities.

Characterizing volatile organic compounds from personal protective equipment users: Implications to cleanroom air quality and occupational health.

Human-related contaminants are the primary pollution source in cleanrooms. This study employed time-of-flight mass spectrometry (PTR-ToF-MS) to characterize volatile organic compound (VOC) emissions from breath and skin under different activity levels and personal protective equipment (PPE) conditions in a climatic chamber. The results show that, without PPE, breath and skin emission rates were 968.

Impact of air conditioning environments on human comfort through exhaled breath and physiological assessments in middle-aged women.

Optimizing indoor thermal environments is crucial for enhancing human comfort, particularly in the context of global warming. By innovatively integrating metabolomics, physiological monitoring, cognitive performance analysis, and subjective comfort evaluations, this study investigated the impacts of three air conditioning (AC) environments on human comfort in 20 middle-aged women volunteers. The three conditions were as follows: (A) refreshing mode, (B) cooling and floor heating modes, and (C) cooling mode at 24 °C with RH 50%.

Non targeted and targeted LC-MS/MS insights into the composition and concentration of atmospheric microplastics and additives: Impacts and regional changes of sandstorms in Shanghai and Hohhot, China.

Increasing dust storms impact ecosystems and human health by resuspending dust and microplastics. Plastic pollution is a major global concern. This study examines the molecular composition and concentration of atmospheric microplastics and additives in Hohhot and Shanghai, China during dust and non-dust days using non-target and target LC-MS/MS analysis with Multiple Reaction Monitoring (MRM) methodology and a self-established plastic monomers database.

Impact of Optimizing the Emergency Care Process on the Emergency Effect and Prognosis of Patients with Hepatic Encephalopathy.

Hepatic encephalopathy (HE) is a serious complication caused by liver disease and is one of the leading causes of death in patients. Studies have shown that proper emergency care for patients after the occurrence of HE can improve their prognosis and quality of life. Therefore, this study focuses on the effect of optimizing the emergency care process on the effectiveness and prognosis of emergency care for patients with hepatic encephalopathy.

The Difficulties and Mental Health Intervention Need of Doctors and Nurses in Biological Emergencies: A Qualitative Study.

When a biological public health event breaks out, due to the characteristics of their work, doctors and nurses must face risks directly when the situation is unknown. Their difficulties and psychological pressure are unimaginable. However, few studies have investigated the difficulties encountered by those doctors and nurses and their requirements for psychological interventions.

Using Mindfulness to Reduce Anxiety and Depression of Patients With Fever Undergoing Screening in an Isolation Ward During the COVID-19 Outbreak.

The coronavirus disease 2019 (COVID-19) continues to spread globally. This infectious disease affects people not only physically but also psychologically. Therefore, an effective psychological intervention program needs to be developed to improve the psychological condition of patients screened for fever during this period.
