Introduction: Uncontrollable nausea and vomiting can cause delay in chemotherapy and affects patient's life. Since Matricaria chamomilla seems to be effective in reducing nausea and vomiting, this study aimed to determine the effect of its extract on the severity of nausea and vomiting due to chemotherapy. Methods: This quasi experimental study was conducted on the patients receiving chemotherapy in Chemotherapy Wards of Zahedan Tamin Ejtemaee Hospitals in 2015. In doing so, 60 patients were selected through convenience-sampling method and assigned into intervention and control groups. Two hours before chemotherapy, the intervention group was given Matricaria chamomilla extract while the control patients were given distilled water as placebo. Nausea rate was measured using Visual Analogue Scale (VAS) 0, 2, 6, and 12 hours after chemotherapy. Results: In the beginning, there was no significant difference between the mean scores of nausea of two groups (P=0.4); however, 2 hours after the chemotherapy, nausea score increased in both groups and it was significantly higher in the control group. (P=0.034). After 6 and 12 hours, the mean scores of nausea in both groups declined; however, the control patients' mean score was constantly and significantly higher. There was no significant difference between the two groups concerning vomiting (P<0.05). Conclusion: The results indicated that consuming Matricaria chamomilla extract can reduce nausea due to chemotherapy while it has no effect on vomiting.

The removal of the chest tube drainage is a painful experience for patients. Painless pain and patient's discomfort is associated with reduced chest dilatation, respiratory dysfunction with hypoxemia, increased sympathetic response to myocardial ischemia, and increased general response to tachycardia. The purpose of this study was to investigate the use of cold compresses before removing the chest drainage tube on the comfort of patients after cardiac surgery. Method: This was a randomized clinical trial with 120 patients undergoing cardiac surgery in Farshchian Hospital in Hamadan in 1395. The research units were randomly divided into three groups of interventional, placebo, and control groups of ICU patients undergoing cardiac surgery and had at least two duct drainage tubes. Cold compresses and placebo were placed around tubes for 20 minutes before removing the chest tubes. The patient's comfort level was measured using the visual analog scale (VAS) before, immediately after and 5 minutes after removal of the chest tube. Data analysis was done using SPSS16, Chi-square, and ANOVA. Results: There was no significant difference between demographic data in the studied groups. However, the average comfort score before, immediately after and 5 minutes after removing chest tube was significantly different in the groups (P =0.000). Conclusion: The results showed that the use of cold compresses around the chest tube before the removal of tubes in patients undergoing heart surgery increases the comfort of the patients.

Increasing the level of knowledge about X-ray protection can play an important role in reducing the effects of radiation. The aim of this study was to investigate the effect of virtual education of nurses on adherence to X-ray protective principles. Methods: This study was a randomized clinical trial on 90 nurses. Educational intervention was virtualized through social network. Questionnaires were completed before and after the intervention in both groups and the data were analyzed by paired and independent t-test using SPSS 24. Results: The mean and standard deviation of the level of protection against xrays in the intervention group before and after the intervention were 15.84±3.64, 30.2±26.3 and in the control group before and after the intervention was 14.08±4.45, 48.14±4.27, respectively. Mean and standard deviation of nurses' performance score before and after intervention in the intervention group were 2.8±1.03, 5.62±0.96 and 3.82±1.07, 3.93±1.03 in the control group before and after the intervention, respectively. The results of paired and independent t-test showed that the mean of performance and the mean score of nurses' knowledge about the application of the principles of X-ray protection before and after the intervention in the intervention group were significantly different; the mean score of nurses' performance and knowledge after intervention was increased (P=0.000). Conclusion: Learning based on cyberspace increases the level of protection knowledge and the performance of nurses against X-rays.
