Background Preserving the health of health care workers (HCWs) has now become one of the main concerns of all countries affected by the coronavirus. Maintaining the health of the hospital workers, especially the medical staff, requires knowledge and awareness, followed by proper behavior for disease prevention and transmission. The purpose of this study was to evaluate the knowledge, attitude and behavior of HCWs to ward patients with suspected or confirmed COVID-19.Methods A cross-sectional study was designed to assess the level of knowledge, attitude and behavior of 191 HCWs of Taleghani Hospital in Kermanshah toward patients with suspected or confirmed COVID-19. Responses to the checklists of demographic characteristics, knowledge, attitude, and behavior toward patients with COVID-19 were analyzed by SPSS 22.Results 191 subjects (118 females and 73 males) with a mean age of 34.7 ± 8.6 years participated in this study. The level of knowledge of HCWs in this study was excellent regarding the ways of transmitting the disease such as close contact with the patient with suspected Coronavirus (99%). According to their positions, participants had a significant difference in their knowledge of asymptomatic patients (P < 0.001). The study found that 14% of the HCWs did not have the necessary knowledge about the symptoms of COVID-19, indicating poor knowledge of the HCWs at the beginning of the disease epidemic. The results obtained from the evaluation of HCWs attitudes showed that some workers believed that protective and preventive measures should only be applied when managing people with severe symptoms (P < 0.001). Finally, there was a significant difference in behavior and adherence to protective and preventive measures between the participants when facing patients with severe symptoms and without symptoms of COVID-19 (P = 0.05).Conclusion Knowledge, attitude, and behavior toward COVID-19 infection and facing patients with severe and overt symptoms among health care workers in the hospital were Excellent, but these were insufficient for patients without obvious symptoms. These results suggest that additional training regarding subclinical cases of Coronavirus is needed for HCWs to protect them from contamination and prevent disease transmission to their colleagues and other patients as well.

Background:Postoperative nausea and vomiting (PONV) is a common complication after general anesthesia, and the prevalence ranges between 25% and 30%. The aim of this study was to determine the preventive effects of dry cupping on PONV by stimulating point P6 in the wrist.Methods:This was a randomized controlled trial conducted at the Imam Reza Hospital in Kermanshah, Iran. The final study sample included 206 patients (107 experimental and 99 controls). Inclusion criteria included the following: female sex; age>18 years; ASA Class I-II; type of surgery: laparoscopic cholecystectomy; type of anesthesia: general anesthesia. Exclusion criteria included: change in the type of surgery, that is, from laparoscopic cholecystectomy to laparotomy, and ASA-classification III or more. Interventions are as follows: pre surgery, before the induction of anesthesia, the experimental group received dry cupping on point P6 of the dominant hand's wrist with activation of intermittent negative pressure. The sham group received cupping without activation of negative pressure at the same point. Main outcome was that the visual analogue scale was used to measure the severity of PONV.Results:The experimental group who received dry cupping had significantly lower levels of PONV severity after surgery (P < 0.001) than the control group. The differences in measure were maintained after controlling for age and ASA in regression models (P < 0.01).Conclusion:Traditional dry cupping delivered in an operation room setting prevented PONV in laparoscopic cholecystectomy patients.
