Reducing airborne transmission of SARS-CoV-2 by an upper-room ultraviolet germicidal irradiation system in a hospital isolation environment
Environ Res. 2023 Aug 22;237(Pt 1):116952. doi: 10.1016/j.envres.2023.116952. Online ahead of print.ABSTRACTUpper-room ultraviolet germicidal irradiation (UVGI) technology can potentially inhibit the transmission of airborne disease pathogens. There is a lack of quantitative evaluation of the performance of the upper-room UVGI for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) airborne transmission under the combined effects of ventilation and UV irradiation. Therefore, this study aimed to explore the performance of the upper-room UVGI system for reducing SARS-CoV-2 virus transmission in a hospital isolation ...

Dispersion of sneeze droplets in a meat facility indoor environment - Without partitions
Environ Res. 2023 Jul 14:116603. doi: 10.1016/j.envres.2023.116603. Online ahead of print.ABSTRACTSpreading patterns of the coronavirus disease (COVID-19) showed that infected and asymptotic carriers both played critical role in escalating transmission of virus leading to global pandemic. Indoor environments of restaurants, classrooms, hospitals, offices, large assemblies, and industrial installations are susceptible to virus outbreak. Industrial facilities such as fabrication rooms of meat processing plants, which are laden with moisture and fat in indoor air are the most sensitive spaces. Fabrication room workers standin...

Production of singlet oxygen from photosensitizer erythrosine for facile inactivation of coronavirus on mask
This study proposes a PPE disinfection method that uses erythrosine, a U.S. Food and Drug Administration-approved food dye, as photosensitizer to produce singlet oxygen for virus inactivation, and indicates the completion of disinfection by its photobleaching color change.After spraying 100 μL of 10 μM erythrosine on the surface of the mask for 3 times and light exposure for 25 min, the titer of coronavirus decreased by more than 99.999%, and the color of erythrosine on the mask surface disappeared. In addition, the structure of the mask was intact and the filtration efficiency was maintained at > 95% after 10 cycles ...

IJERPH, Vol. 20, Pages 5799: Retrospective Analysis of the Outcome of Hospitalized COVID-19 Patients with Coexisting Metabolic Syndrome and HIV Using Multinomial Logistic Regression
ua Modjadji
Globally, the coexistence of metabolic syndrome (MetS) and HIV has become an important public health problem, putting coronavirus disease 19 (COVID-19) hospitalized patients at risk for severe manifestations and higher mortality. A retrospective cross-sectional analysis was conducted to identify factors and determine their relationships with hospitalization outcomes for COVID-19 patients using secondary data from the Department of Health in Limpopo Province, South Africa. The study included 15,151 patient clinical records of laboratory-confirmed COVID-19 cases. Data on MetS was extracted in the form of a cl...

Long-term exposure to air pollution and COVID-19 severity: A cohort study in Greater Manchester, United Kingdom
Environ Pollut. 2023 Apr 6:121594. doi: 10.1016/j.envpol.2023.121594. Online ahead of print.ABSTRACTExposure to outdoor air pollution may affect incidence and severity of coronavirus disease 2019 (COVID-19). In this retrospective cohort based on patient records from the Greater Manchester Care Records, all first COVID-19 cases diagnosed between March 1, 2020 and May 31, 2022 were followed until COVID-19 related hospitalization or death within 28 days. Long-term exposure was estimated using mean annual concentrations of particulate matter with diameter <2.5 μm (PM2.5), <10 μm (PM10), nitrogen dioxide (NO2), ozone (O...

IJERPH, Vol. 20, Pages 4718: Impact of Unexpected In-House Major COVID-19 Outbreaks on Depressive Symptoms among Healthcare Workers: A Retrospective Multi-Institutional Study
This study retrospectively examines depressive symptoms before psychosocial interventions among HCWs working at typical hospitals and nursing homes experiencing in-house major COVID-19 outbreaks. We have offered psychosocial support in eight hospitals and nursing homes, obtaining data on the mental health status of 558 HCWs using the Patient Health Questionnaire-9. The study&rsquo;s results indicate that 29.4% of HCWs have exhibited moderate or higher depressive symptoms, and 10.2% had suicidal ideation. Multiple logistic regression analysis showed that being a nurse was associated with higher depressive symptoms a...

IJERPH, Vol. 20, Pages 4434: Preventive Measures among Healthcare Workers (HCWs) during the COVID-19 Pandemic
sa Rivera-Amill
COVID-19, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), placed health systems worldwide under immense pressure, and healthcare workers (HCWs) were at the front lines. The Puerto Rico Department of Health confirmed the first case of COVID-19 in March 2020. We aimed to assess whether COVID-19 preventive measures implemented by HCWs were effective in a work scenario before vaccine availability. We conducted a descriptive cross-sectional study from July to December 2020 to evaluate the use of personal protective equipment (PPE), hygiene guidelines, and other measures taken by H...

IJERPH, Vol. 20, Pages 3735: Did the COVID-19 Pandemic Restrict Access to Emergency Urological Services: Assessment of Reorganisation Effectiveness for Hospital Treatment
Słojewski
Urolithiasis derived renal colic is a common urological condition. If treated properly, the disease resolves without complications; if not treated, it causes infection and renal failure. The COVID-19 restrictions impacted hospitalised treatment of diseases. We analysed the impact of COVID-19 on renal colic treatment at a hospital in Poland. Clinical and demographic data of patients treated during the COVID-19 era were compared with those treated before this pandemic. During the COVID-19 restrictions, renal colic patient hospital admissions fell significantly. However, more patients presented with chronic ren...

Anran Yang
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has spread across the globe since the end of 2019, posing significant challenges for global medical facilities and human health. Treatment of hospital wastewater is vitally important under this special circumstance. However, there is a shortage of studies on the sustainable wastewater treatment processes utilized by hospitals. Based on a review of the research trends regarding hospital wastewater treatment in the past three years of the COVID-19 outbreak, this review overviews the existing hospital wastewater treatment processes. It is clear tha...

IJERPH, Vol. 20, Pages 2713: The Influence of the COVID-19 Pandemic on Emergency Medical Services to Out-of-Hospital Cardiac Arrests in a Low-Incidence Urban City: An Observational Epidemiological Analysis
g-Chuan Cai
The Emergency Medical Services (EMS) system faced overwhelming challenges during the coronavirus disease 2019 (COVID-19) pandemic. However, further information is required to determine how the pandemic affected the EMS response and the clinical outcomes of out-of-hospital cardiac arrest (OHCA) patients in COVID-19 low-incidence cities. A retrospective study was conducted in Chiayi, Taiwan, a COVID-19 low-incidence urban city. We compared the outcomes and rescue records before (2018&ndash;2019) and during (2020&ndash;2021) the COVID-19 pandemic. A total of 567 patients before and 497 during t...
