Abstract
Aim. The aim of this study was to examine the effect of self-management training and follow-up with phone calls or mobile social network on the blood pressure of people with hypertension.
Background. Hypertension is one of the main causes of preventable death worldwide, and self-management training and follow-up is of particular importance in these patients.
Method. This randomized controlled clinical trial was conducted on 100 patients with primary hypertension referred to AL-Zahra hospital, Isfahan, Iran in 2016. The patients were recruited through convenience sampling and were allocated by blocking randomization into four groups, control group, “self-management education without follow-up” group, “self-management education by social network follow-up” group (education and weekly follow-up for 6 weeks) and “self-management education by telephone follow-up” group (education along with weekly calls for 6 weeks). Data were collected before and 6 weeks after intervention. The data were analyzed using Chi-square test, ANOVA, and paired t-test in SPSS, version 16.
Findings. After intervention, the study groups were significantly different in terms of blood pressure (P ≤0.0001). According to Scheffe post hoc test, intervention groups (with and without follow-up) had a statistically significant difference regarding to the blood pressure when compared with compared with the control group (P≤0.0001). Scheffe post hoc test results showed that three interventions (education without follow-up, education with telephone follow-up and education with social networks follow-up) did not differ in terms of effect on systolic and diastolic blood pressure.
Conclusion. Self-management training and follow-up by telephone or mobile social network were effective on the blood pressure of people with hypertension. Nurses can take a positive step towards improving the management of hypertension with a comprehensive patient education and follow-up.

Abstract
Aim. This Study aimed to examine the effect of social networking education on blood glucose control and post-surgical infections after open heart surgery in diabetic patients.
Background. Cardiovascular surgery is one of the most common surgeries that is performed with the aim of increasing survival and improving the quality of life in diabetic patients.
Method. This randomized clinical trial study was conducted on 120 diabetic patients (age range 18-60 years) who underwent open heart surgery at Shahid Rajaei Cardiovascular Research and Research Center. The participants were randomly divided into experimental (n=60) and control group (n=60). In the experimental group, posts were delivered to patients with educational content (such as nutrition education, blood sugar self-monitoring, and ...) on a daily basis for three months on the WhatsApp social network. Data were collected by a checklist consisting of three parts: demographic characteristics, fasting blood sugar (FBS) and glycosylated hemoglobin (HbA1c) of patients before and 3 months after the intervention.
Findings. In both experimental and control group, 55 percent were male and 45percent were female. The percent of patients with postoperative wound infection in the experimental and control groups was 5.0 and 3.3, respectively. After intervention, in the experimental group, the FBS and Hb1Ac median was significantly reduced compared to before the intervention (p<0.001). The levels of FBS and Hb1Ac before and after the intervention did not differ significantly between the experimental and control group.
Conclusion. There was no different between groups in terms of blood sugar control and wound infections after open heart surgery. Due to the easy access, lack of time and space limitations of using social networks, further studies with longer follow-up are recommended.
