 Diabetes is one of the main problems of health systems and a global threat to public health that has increased dramatically over the past two decades. Patients with diabetes are susceptible to multiple complications, such as diabetic foot ulcers. A diabetic foot ulcer is a common diabetes complication that has shown an increasing trend over the past decades. In treating diabetic foot ulcers, using ulcers with wound treatment is one of the critical challenges for therapists. So far, the dressing that meets all the requirements for the treatment of diabetic foot ulcers has not been produced, and the proper choice of sauce depends on the type and stage of the wound, the spread of the injury, the patient's condition, and the tissues involved.

 The present study was conducted using the one-blind clinical work method on 80 diabetic patients referred to the Alborz University of Medical Sciences supervised clinics; 40 patients with diabetic foot ulcers were treated and compared to algae, and 40 patients with alginate dressing. The information collected was analyzed using Chi-Square and T statistical tests.

There were no significant differences in gender, education level, marital condition, land disease, wound time, size, and secretion. In comparing the body mass index, there was no significant difference between the two groups in consequence of wound healing. The recovery percentage in the Alji Pad group was significantly better than in the alginate group. Also, the number of sessions for each patient in the Alji Pad group was considerably lower than in the alginate group. In reviewing the Push scoring process, we evaluated the fifth referral. Because in both groups, most people went to the fifth session. We used repeated measurement analysis. The results showed that the recovery process was good in the two groups (P <0.001), but the recovery in the Alji Pad group was significantly faster than in the alginate group.

 Algae Pad dressing in patients with diabetic foot ulcers is a simple and practical method that, according to the study of the cost of treatment, the duration of treatment is preferable to the conventional alginate dressing method.

Many elderly patients after admission to the cardiac care unit (CCU) are exposed to factors such as stress, which face them with changes in vital signs that these changes could adversely affect these patient's recovery. This study aimed to determine the effect of white noise on the vital signs of elderly patients in the CCU.

This is a quasi-experimental study in which 59 elderly patients in the cardiac intensive care unit of Shaheed Rajai Tehran Heart Center were studied. In this study, samples were selected through convenience sampling and randomly divided into two groups: experimental and control. Vital signs were measured in both groups for 3 consecutive days by charting vital signs. During this period, for the experimental group, white noise with an intensity of 50 to 60 decibels was played for 30 minutes during the day and the elderly patient's vital signs were recorded before and after the intervention, the control group did not have any intervention. Data were analyzed by SPSS, Version 18, by using independent t-test, paired t-test and Chi-square test.

In the present study, 27 elderly patients in the control group and 32 patients in the intervention group were examined. The findings showed that the white noise significantly reduced heart rate in the intervention group compared with the control group (P=0.02), but comparing other variables such as, systolic blood pressure (P=0.89) , diastolic blood pressure (P=0.73) and respiratory rate (P=0.07) did not show significant differences between the two groups.

According to the results of this study use of white noise can reduce heart rate of elderly patients admitted to the CCU.
