Assessment of Knowledge, Attitude, and Practices Toward Coronavirus Disease 2019 and the Risks of Severe Acute Respiratory Syndrome Coronavirus 2 Infection Among Iranian Emergency Medical Services Workers: An Online Cross-Sectional Survey.

OBJECTIVE: Coronavirus disease 2019 (COVID-19), a severe acute respiratory infection, has spread rapidly around the world. To expand and enhance knowledge regarding virus prevention/transmission, this study aimed to evaluate the knowledge, attitudes, and practices of emergency medical services (EMS) workers as a part of the health care system because of their essential role in the front lines of the COVID-19 outbreak. METHODS: An online cross-sectional survey was conducted on EMS workers to assess their knowledge, attitudes, and practices toward COVID-19. The questionnaire included 5 topics: demographic information, knowledge and attitude questions, professional behavior of employees during the epidemic, and anxiety score. RESULTS: A total of 86 EMS workers answered the questionnaire, and 55.63% of the respondents answered the knowledge questions correctly; knowledge appeared to have no correlation to their education, age, or experience. In addition, there was no apparent correlation between the infection rate and exposure to an infected or suspected patient. CONCLUSION: The findings of the present study indicate that more than half of the EMS workers have good knowledge about the epidemic, and the level of knowledge was not related to their demographic characteristics. The results of professional behaviors showed a high level of compliance with the principles and guidelines by workers, and the absence of a relationship between employees' contamination and exposure to infected patients supports the awareness and legality of EMS workers.

Evaluation of Lactocare® Synbiotic Administration on the Serum Electrolytes and Trace Elements Levels in Psoriasis Patients: a Randomized, Double-Blind, Placebo-Controlled Clinical Trial Study.

BACKGROUND: Despite the exact etiopathogenesis of psoriasis remains unknown, the increasing or decreasing of some trace elements and oxidative stress status are considered to play a role. In this study, the effect of Lactocare® synbiotic on the serum levels of trace elements including Zn, Cu, Mg, Na, Fe, P, Ca, and K in the patients with mild to moderate psoriasis was investigated. METHODS: Sixty-four patients with mild to moderate psoriasis were included. Patients were randomly divided into treatment (n═32) and control (n═32) groups. The treatment group received Lactocare® and the control group received a placebo (two times daily for 12 weeks). Eight patients from the intervention group and 18 patients from the control group discontinued the study because of the recent COVID-19 condition. For routine trace element analysis, the blood samples were collected from all patients at the baseline as well as week 12 post-treatment. The serum was then isolated and the serum levels of trace elements including Fe, K, Ca, Mg, P, Zn, Na, and Cu were measured using an automatic electrolyte analyzer. For confirmation of the effect of Lactocare® on the alteration of serum levels of trace elements, intra-group analysis was performed at two interval times: baseline and week 12 post-treatment. RESULTS: The serum levels of K, P, and Ca in the placebo group were significantly higher than that of the treatment group at baseline. Serum levels of Zn and Ca were significantly higher in the treatment group compared to the placebo group at week 12 post-treatment. Moreover, a significantly lower serum level of K, P, and Ca in the treatment group at the baseline compared to the placebo group was compensated on week 12 post-treatment. Intra-group analysis in the treatment group showed that the serum levels of Fe, Ca, Mg, P, Zn, and Na was significantly increased at week 12 post-treatment compared to baseline levels. Whereas, intra-group analysis in the control group showed only Ca has a significant difference between baseline and week 12 post-treatment. CONCLUSION: The serum levels of Fe, Zn, P, Mg, Ca, and Na are increased significantly 12 weeks after oral administration of Lactocare® in psoriatic patients. The serum level of Fe and Cu is affected by sex at pre- and post-treatment. This study supports the concept that Lactocare® exerts beneficial effects in the gastrointestinal tract to improve mineral absorption in psoriatic patients.
