Perspectives of dermatology specialists and residents on COVID-19 vaccines: a questionnaire-based survey

AbstractBackground: To evaluate the perspectives of dermatology specialists and residents on coronavirus disease 2019 (COVID-19) vaccines.Methods: Present questionnaire-based study was conducted on dermatology resi dents and specialists between January 5 and 20. A non-validated online questionaryevaluating the attitude of the participants about the COVID-19 vaccine was per formed. In the first step of the study, data related to the demographic features, all par ticipants' clinical characteristics, and working conditions were recorded. Thereafter answers given to 12 specific questions were recorded. The study population was divided into two groups: dermatology residents (n = 138) and specialists (n = 159). Mentioned variables were compared between the two defined groups. Furthermore, a correlation analysis was performed to assess the relationship between vaccination acceptance and various study parameters.Results: Majority of the cases had positive attitudes against COVID-19 vaccines. However, there were significant differences between the resident and specialist groups related to the source of information, working conditions, degree of concern, and type of vaccines. Statistically significant negative, weak correlations were observed for age and duration of medical practice (r = -.128, P = .028; r = -.132, P = .041 respectively). Statistically significant positive weak correlations were observed for chronic diseases, level of knowledge about COVID-19 vaccines, number of information sources about COVİD-19, and previous COVİD-19 infection (r = .133, P = .021; r = .207, P < .001; r= .335, P < .001; r = .176, P = .002 respectively).Conclusion: The acceptance of COVID-19 vaccination may be affected by working conditions, medical experience, level of knowledge and the presence of risk factors for severe disease among dermatology residents and specialists

Evaluation of effectiveness of cold atmospheric plasma treatment methods for prevention of ventilator-associated pneumonia

Hospital-acquired infections (HAI) (nosocomial infection) are serious health problems that occur when person acquires infection during stay in a hospital for causes other reasons than that infection. Colonization of microorganisms pave the way for deaths, in detail, Ventilator Associated Pneumonia (VAP) is remarkable in terms of mortality accounted for 15% of nosocomial infections. Ventilator associated pneumonia (VAP) is common a disease, especially among patients that are on connected ventilators in intensive care units. It is defined as the pneumonia, in which occurs in at least 48 hours after mechanical ventilation, is provided via endotracheal tubes or tracheostomy. This infection occurs because of assault of microorganisms that settle in endotracheal tubes in respiratory tract and then in lung parenchyma tissue. The most common settling organisms in respiratory tract are S.aureus, P. aureginosa, K. pneumonia, E.coli and Acinetobacter, Candida, Enterobacter species. Due to multi drug resistant microorganisms, the current treatments are inadequate and the mortality rate increases. Therefore, plasma can play significant role for the management of ventilator-associated pneumonia. Plasma is ionized gas and defined as the fourth state of matter. The treatments of plasma in health care can ensure quick and pretty effect to protect from resistant microorganism to antibiotics to patients. The purpose of present study is to develop a method of plasma treatment which can be utilized for the control and prevention of ventilatör associated pneumonia. For this concept, we have designed different systems and determined optimum parameters to prevent and eradicate biofilms of Staphylococcus aureus, Acinotabacter baumannii, Pseudomonas aureginosa, and Candida Albicans in endotracheal tubes. Our results indicate that, various plasma treatment modalities are capable of prevention and eradication of biofilms grown in endotracheal tubes. Therefore, cold atmospheric pressure plasma treatment methods could be considered as for the management of ventilator associated pneumonia
