ABSTRACT

The novel coronavirus disease-2019 (COVID-19) illness and deaths, caused by the severe acute respiratory syndrome coronavirus-2, continue to increase. Multiple reports highlight the thromboembolic complications, such as pulmonary embolism (PE), in COVID-19. Imaging plays an essential role in the diagnosis and management of COVID-19 patients with PE. There continues to be a rapid evolution of knowledge related to COVID-19 associated PE. This review summarizes the current understanding of prevalence, pathophysiology, role of diagnostic imaging modalities, and management, including catheter-directed therapy for COVID-19 associated PE. It also describes infection control considerations for the radiology department while providing care for patients with COVID-19 associated PE.

ABSTRACT

Introduction: Healthcare workers are at an increased risk of infectious disease transmission through occupational exposure. Despite this, rates of personal protective equipment (PPE) use vary among healthcare personnel. This cross-sectional study surveyed healthcare workers at a single academic center to determine how the coronavirus disease 2019 (COVID-19) pandemic affected the perceptions and behaviors of PPE usage. Methods: An anonymous online survey through the SurveyMonkey® tool (Zendesk Inc., San Francisco, California) was sent to the University of California, Irvine, Medical Center department listserv of nurses on March 20, 2021, and was closed on June 20, 2021. Results: Of 311 respondents, 23% admitted to suffering a splash injury to the face during a procedure. When compared to one year ago prior to the COVID-19 pandemic, PPE was more important (93% vs. 80%) and more frequently used (80% vs. 54%) by respondents. The recent COVID-19 pandemic had the strongest impact on increasing respondents’ perception of the importance of PPE (44%). Conclusion: The COVID-19 pandemic positively impacted rates of PPE usage and perceptions of the importance of PPE among healthcare workers at a single academic institution. Implementing clear and effective education and training programs, ensuring adequate access to protective gear, and promoting a positive safety climate can help improve adherence to safety protocols and appropriate use of PPE.

ABSTRACT

Face masks have been an effective and indispensable personal protective measure against particulate matter pollutants and respiratory diseases, especially the novel Coronavirus disease recently. However, disposable surgical face masks suffer from low filtration efficiency for particles ranging from nano- to micro-size, and the limited service life of ~ 4h. Here, a nano/micro fibrous hybrid air filter mask composing of electrospun nanofibrous network and poly(3,4-ethylenedioxythiophene:poly(styrenesulfonate) coated polypropylene (PP) is proposed. Furthermore, the resultant filter is supplied with tribo-charges by a freestanding sliding triboelectric nanogenerator. Through the enhanced synergistic effect of mechanical interception and electrostatic forces, the hybrid air filter demonstrates high filtration efficiency for particle size of 11.5nm to 2.5µm, with a 9.3–34.68% enhancement for particles of 0.3–2.5µm compared to pristine PP, and 48-h stable filtration efficiency of 94% (0.3–0.4µm) and 99% (1–2.5µm) with a low pressure drop of ~110Pa. In addition, sterilization ability of the tribo-charge enhanced air filter is demonstrated. This work provides a facile and cost-effective approach for state-of-the-art face masks toward high filtration performance of nano- to micro- particles with greatly extended service life.

ABSTRACT

During the COVID-19 pandemic, many hospitality organizations are trying to help their employees overcome various challenges. Career adaptability has proven to be useful in helping employees handle challenges, while proactive personality is a critical factor affecting the formation of career adaptability. However, career adaptability can be a double-edged sword, and it is unclear how it may impact employees' turnover intentions. Drawing on social exchange theory, the current study reconciles mixed findings in the literature by proposing a moderated mediation model suggesting that work social support moderates the indirect relationship between proactive personality and turnover intentions through career adaptability. Results based on data collected from 339 hotel employees in the United States indicate that proactive personality is positively associated with employees' career adaptability. More importantly, work social support significantly moderates the relationship between career adaptability and turnover intentions. Theoretical and managerial implications are discussed.
