During events that threaten people's health, high concentrations of pollutants in the air, outbreaks of diseases transmitted by airborne droplets, special filtering means of protection are used. If used correctly, respirators can reduce the risk of exposure to airborne particles, including aerosols of biological and non-biological origin. Mats Friberg tells about what you should pay attention to when choosing respiratory protection products and how to use them correctly.

Abstract ObjectivesTo reduce the spread of the infection, especially during aerosol generating procedures, we invented “The Cupola”, a shield that creates a mechanical barrier around the patient’s head and body. With this pilot study we aimed to assess the effectiveness of an additional layer of protection (The Cupola) developed for providers working in the oropharyngeal region.ResultsThe mean number of 0.3 μm particles with no Cupola was 3777 (SD: ±556), with The Cupola was 2068 (SD: ±1468) and with the Cupola and Drape was 2031 (SD: ±1108) (p<0.015). The mean number of 0.5 μm airborne particles with no Cupola was 65 (SD: ±7), with The Cupola was 29 (SD: ±28) and with the Cupola and Drape was 28 (SD: ±23) (p<0.05). Results showed a significant reduction of aerosols generated during simulated dental procedures when the Cupola was used. The Cupola offers an extra layer of protection in addition to the recommended personal protective equipment.

The mean number of 0.5 μm airborne particles with no Cupola was 65 (SD: ± 7), with The Cupola was 29 (SD: ± 28) and with the Cupola and Drape was 28 (SD: ± 23) (p < 0.05). Results showed a significant reduction of aerosols generated during simulated dental procedures when the Cupola was used.

The worldwide spread of coronavirus COVID-19 infections demonstrates the great need for personal protective equipment and, in particular, hygiene masks. These masks are essential for the primary protection of the respiratory tract against pathogens such as viruses and bacteria that are infectious and transmitted through the air as large droplets or via small airborne particles. The use of protective masks will continue to accompany humans for an indefinite period of time, and therefore there is an urgent need for a safe method to extend their usability by reusing them under perspective with minimal loss of protective properties. Nanofiber mats are widely used in masks and in this study the reusability of nanofiber mats is investigated by washing them at different temperatures. This paper shows the first measurements of the washability of nanofiber mats. Furthermore, the air permeability is measured, and the evaporation resistance is evaluated. According to the results of this study, the air permeability performance of nanofiber mats does not change significantly after washing, confirming the possibility of reuse.

BACKGROUND COVID-19 is a health emergency. It was found in Wuhan, Hubei Province, China and has rapidly spread around the world, leaving no country untouched. SARS-CoV-2 is a respiratory infection characterised by a pneumonia of unknown aetiology. It is transmitted through respiratory droplets, for example: when breathing, talking and coughing. Transmission of the virus is high. Healthcare workers play critical roles in providing help to those affected with COVID-19; this could not be done without the use of personal protective equipment. Personal protective equipment, also known as PPE, involves the use of goggles, masks, gloves and gowns with the aims of protecting healthcare workers and reducing the transmission of the virus. PPE has proven to be effective in reducing the transmission of the virus, however multiple reports of skin disease and damage associated with occupational mask wear have come to light. OBJECTIVE The objective is to review current literature of newly arising dermatological conditions as a result of occupational mask wear during the COVID-19 pandemic. METHODS A qualitative review investigating new reports of dermatological conditions associated with occupational mask wear was carried out by referencing keywords, including: “covid mask dermatology, covid mask skin and covid mask skin damage” from the databases of PubMed, Google Scholar and ResearchGate. 287 articles were found (PubMed: 59, Google Scholar: 90, ResearchGate: 138); 40 articles successfully formed part of the study. A further 7 articles were found by manually reviewing reference lists of the included articles. The findings were tabulated and analysed under the headings: dermatological diagnosis, causes and management. RESULTS Qualitative analysis of the reviewed data was carried out. A number of dermatological conditions, as listed in Table 1, were found to be increasing due to prolonged and frequent contact of facial masks. The number of healthcare workers affected by symptoms of skin damage was significant in almost all studies, showing a worldwide problem was present. Pressure-related injuries were often the most serious complaint; recommendations to reduce this type of injury include hydrocolloid dressings, plastic handles, education and regular moisturising. Innovation of protective equipment as well as services, such as virtual clinics, need to be advanced to protect the welfare of staff. CONCLUSIONS In these unprecedented times, PPE has been an effective barrier in reducing the transmission of COVID-19 to healthcare workers. This has allowed healthcare workers to bravely provide care to patients. However, the evidence collated suggests that despite the obvious benefits of using facial masks to protect the respiratory system, there are also considerable health consequences to the skin. Future research needs to pursue the advancement of facial masks which considers both the protection of the respiratory system as well as skin care, something which this review demonstrates has been neglected.

Abstract Introduction Preparations of health systems to accommodate large number of severely ill COVID-19 patients in March/April 2020 has a significant impact on nuclear medicine departments. Materials and Methods A web-based questionnaire was designed to differentiate the impact of the pandemic on inpatient and outpatient nuclear medicine operations and on public versus private health systems, respectively. Questions were addressing the following issues: impact on nuclear medicine diagnostics and therapy, use of recommendations, personal protective equipment, and organizational adaptations. The survey was available for 6 days and closed on April 20, 2020. Results 113 complete responses were recorded. Nearly all participants (97 %) report a decline of nuclear medicine diagnostic procedures. The mean reduction in the last three weeks for PET/CT, scintigraphies of bone, myocardium, lung thyroid, sentinel lymph-node are –14.4 %, –47.2 %, –47.5 %, –40.7 %, –58.4 %, and –25.2 % respectively. Furthermore, 76 % of the participants report a reduction in therapies especially for benign thyroid disease (-41.8 %) and radiosynoviorthesis (–53.8 %) while tumor therapies remained mainly stable. 48 % of the participants report a shortage of personal protective equipment. Conclusions Nuclear medicine services are notably reduced 3 weeks after the SARS-CoV-2 pandemic reached Germany, Austria and Switzerland on a large scale. We must be aware that the current crisis will also have a significant economic impact on the healthcare system. As the survey cannot adapt to daily dynamic changes in priorities, it serves as a first snapshot requiring follow-up studies and comparisons with other countries and regions.

The article shows that in the daily activities of nursing staff of functional diagnostics departments (offices), it is necessary to strictly observe the requirements and rules for the prevention of infections associated with medical care, especially during the COVID-19 pandemic. The types of personal protective equipment (PPE) of medical personnel (MP), as well as current effective methods of disinfection, rules for collecting medical waste in a complex epidemiological situation are presented.
