Abstract
Air quality in a cancer facility is integral to the success of patient treatment. The organization must be committed to providing a patient care environment free of physical and biological hazards that result from construction and demolition activities. This project intended to safely demolish a derelict building in Texas while minimizing air quality risks and impacts to nearby hospitals and a proximal cancer hospital. Two of the neighboring facilities were less than 18 feet (5.5 m) away from the demolition location. Adjacent facilities included inpatient and outpatient cancer treatment clinics, a large data center, a pediatric hospital complex, and a heart institute. Plans to minimize infection risks and dust for respective facilities were designed before implosion and remained in place until total debris removal. Risk assessments of nearby buildings were completed to determine the appropriate precautions and physical barriers needed. Culturable and non-culturable fungal air samples were collected during implosion to verify the management of outside contaminants. Additionally, continuous particulate and routine sampling for culturable and non-culturable fungi were performed for approximately 7 months after the project demolition. Air sampling results from 32 internal areas indicated that most areas remained at pre-implosion background levels. Areas that experienced elevated particle counts were cleaned and resampled, and baseline values returned to pre-implosion levels within 12 hr. Fungal air sampling results were acceptable based on predetermined infection control guidelines. The building was successfully demolished via implosion with no injuries and minimal damage to nearby facilities. The team learned that an integrated approach to project management that includes all stakeholders is essential to success. Contingency planning should account for all variables; no assumptions should be made. Staffing plans should be reviewed to ensure the sampling strategy developed can be implemented appropriately.

Air Sampling for Fungus around Hospitalized Patients with Coronavirus Disease 2019. J Fungi (Basel) 2022; 8:jof8070692. [PMID: 35887448 PMCID: PMC9321969 DOI: 10.3390/jof8070692] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 06/29/2022] [Accepted: 06/29/2022] [Indexed: 11/17/2022] Open
Abstract
The risk of developing coronavirus disease 2019 (COVID-19)-associated pulmonary aspergillosis (CAPA) depends on factors related to the host, virus, and treatment. However, many hospitals have modified their existing rooms and adjusted airflow to protect healthcare workers from aerosolization, which may increase the risk of Aspergillus exposure. This study aimed to quantitatively investigate airborne fungal levels in negative and slightly negative pressure rooms for COVID-19 patients. The air in neutral pressure rooms in ordinary wards and a liver intensive care unit with high-efficiency particulate air filter was also assessed for comparison. We found the highest airborne fungal burden in recently renovated slightly negative air pressure rooms, and a higher airborne fungal concentration in both areas used to treat COVID-19 patients. The result provided evidence of the potential environmental risk of CAPA by quantitative microbiologic air sampling, which was scarcely addressed in the literature. Enhancing environmental infection control measures to minimize exposure to fungal spores should be considered. However, the clinical implications of a periodic basis to determine indoor airborne fungal levels and further air sterilization in these areas remain to be defined.

Abstract
Chronic pulmonary aspergillosis (CPA) is an emerging disease in patients with common chronic pulmonary diseases (CPDs). While its prevalence is linked to tuberculosis (TB) in endemic countries, epidemiological and prognostic data are lacking in low TB incidence countries. The aim of this study was to describe these features in CPA patients hospitalised in France between 2009 and 2018.We estimated the prevalence and mortality of hospitalised CPA patients using the French nationwide administrative hospital database. We also assessed the association with CPD, thoracic interventions and malnutrition.From 2009 to 2018, 17 290 patients were hospitalised in France for CPA, with an increasing prevalence during this period. Most patients were male (63.5%) with a median age of 65 years at CPA diagnosis, living in farming regions and large cities. The proportion of underlying chronic obstructive pulmonary disease (COPD) and emphysema during the previous 5 years was 44% and 22%, respectively, whereas it was only 3% for both TB and non-TB mycobacterial (NTM) infections. The mortality rates during the first hospitalisation, at 1 year and at 5 years were 17%, 32% and 45%, respectively. In multivariate analysis, mortality rates were increased in patients aged >65 years, male patients and patients with malnutrition, diabetes or lung cancer history. The risk of mortality in patients with COPD or emphysema was higher than in those with previous mycobacterial lung infection.In France, CPA is an emerging infection commonly associated with non-mycobacterial CPD. This shift in the distribution profile of underlying CPD will likely worsen CPA mortality.
