Introduction: Integrating traditional Chinese medicine with Western medicine has been extensively studied in managing respiratory disease. Therefore, in this study, we aimed to examine interferon point alteration (IPA) and its association with disease severity in patients with COVID-19.

Methods: This cross-sectional study was conducted on patients hospitalized due to COVID-19 with lung involvement.

Background: Resistance to carbapenems, the first-line treatment for infections caused by Acinetobacter baumannii, is increasing throughout the world. The aim of the present study was to determine the global status of resistance to carbapenems in clinical isolates of this pathogen, worldwide.

Methods: Electronic databases were searched using the appropriate keywords, including: 'Acinetobacter' 'baumannii', 'Acinetobacter baumannii' and 'A.

Background: The effects of COVID-19 vaccines on immunocompromised people such as hemodialysis (HD) patients are an important topic that should be addressed. This study reports an observation of the effect of the third dose of the Sinopharm vaccine (SphV3) on the level of hepatitis B surface antibody (anti-HBs) in HD patients, and the differences between anti-HBs titers before and after SphV3 were analytically evaluated.

Methods: This single-center observational study involved all HD patients presented to Shariati Hospital, Tehran, Iran, from February 2021 to March 2022.

Human-Building Interaction (HBI) is a convergent field that represents the growing complexities of the dynamic interplay between human experience and intelligence within built environments. This paper provides core definitions, research dimensions, and an overall vision for the future of HBI as developed through consensus among 25 interdisciplinary experts in a series of facilitated workshops. Three primary areas contribute to and require attention in HBI research: humans (human experiences, performance, and well-being), buildings (building design and operations), and technologies (sensing, inference, and awareness).

As humans spend more time indoors, ensuring acceptable indoor air quality (IAQ) through ubiquitous sensing systems has become a necessity. Although extensive studies have been conducted on the IAQ sensing systems, a holistic review of the performance and deployment of Ubiquitous IAQ Sensing (UIAQS) systems with associated requirements in IAQ sensing standards is still lacking. In this study, we first reviewed IAQ pollutants and other IAQ-related factors and the associated requirements in the prominent IAQ sensing standards.

Human activity is known to leave significant effects on indoor airflow patterns. These patterns are carefully designed for many facilities such as cleanrooms, pharmaceutical settings, and healthcare environments, where human-induced wakes contribute to the transport of contaminants. Therefore, the knowledge about these wakes as it relates to indoor air quality is critical.

Inhalation exposure to pure and metabolic elevated carbon dioxide (CO) concentration has been associated with impaired work performance, lower perceived air quality, and increased health symptoms. In this study, the concentration of metabolic CO was continuously measured in the inhalation zone of 41 subjects performing simulated office work. The measurements took place in an environmental chamber with well-controlled mechanical ventilation arranged as an office environment.
