Abstract
Background: Permanent pacemakers are applied to treat some 2nd and 3rd degree AV blocks. Previous studies have shown the hemodynamic changes that may occur after pacemaker implantation. In this study, we have evaluated these hemodynamic changes from a different view point, with measurement of urinary sodium and blood pressure. Materials and Methods: This is a before and after clinical trial study in which 30 patients, who were hospitalized for permanent pacemaker implantation for the first time in Tehran heart center during 3 years, including 12 women (mean age 62.92 years) and 18 men (mean age 60.07 years), were tested for urinary specific gravity and sodium, blood pressure, blood sodium and potassium, before and after pacemaker implantation. Paired sample T test and Chi Square test were used for statistical analysis. Results: Systolic blood pressure was 136.5 mmHg and 120.6 mmHg before and after pacemaker implantation, (P<0.001). Also, after pacemaker implantation, urinary sodium rose from 83.45 meq/L to 106.61 meq/L (p=0.018). Conclusion: This study is consistent with previous studies, which showed hemodynamic changes after permanent pacemaker implantation including decrease in blood pressure and elevation of serum neuropeptides.

Abstract
Background: High blood pressure (HBP) is one of the effective risk factors for many diseases. Hence, a variety of studies have been done for identifying its risk factors which have led to the diagnosis of different factors, among which working on shift work (WSW) can be mentioned. In this longitudinal study, we deal with the effect of WSW on BP by controlling the confounding factors through GEE regression which is a powerful tool for correlational and longitudinal data analysis. Materials and Methods:In this retrospective cohort study, data collection was done through annual observations of health and safety executive (HSE) center of Mobarakeh Steel Company (MSCO) of Isfahan on the workers in 2007-2009. For data analysis, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were regarded as dependent variables, whereas body mass index (BMI), age, education level (EL), and shift work were considered independent variables. SPSS version 15 was used to apply GEE regression to the assessment of parameters corresponding to the factors causing change in SBP and DBP. Results: Of the independent variables, BMI and age had a significant relationship with SBP and DBP however, the results did not indicate any significant relationships between BP and WSW and EL. Conclusion: In this study, there was not a significant relationship between shift work and BP. This can be attributed to the likelihood of SWS being healthier, as well as the flexibility of work hours, income, and more intervals for shift workers in comparison to day workers.

Abstract
Background: The most common reasons for discontinuation of Depot Medroxy Progesterone Acetate (DMPA) contraceptive method are irregular bleeding and increased body weight. To reduce these complications, the combined injectable contraceptive drug, cyclofem, is offered as an alternative while its effects on the reduction of these complications are not quite clear. Thus this study was done to compare the effects of cyclofem and DMPA on the pattern of bleeding, body weight, and blood pressure variations. Materials and Methods: In a cross-sectional study, 600 healthy women using DMPA and cyclofem) 300 people in each group (were selected through purposeful sampling and evaluated in 3 time intervals: 3, 6 and 9-12 months after primary injection. Data were collected by questionnaire and analyzed by Chi-square, ANOVA, and Mann-Whitney tests using SPSS software. Results: Spotting and amenorrhea were seen with higher incidence in DMPA users. There was a significant difference between DMPA and cyclofem users in spotting at the end of months 3, 6, and 9-12 after the first injection (p<0.05). Also, there was a significant difference between the two groups in amenorrhea during the three intervals (p<0.05). There was not a significant difference between the two groups in terms of weight variations (p>0.05), but there was a significant difference between the two groups in diastolic blood pressure (p<0.05). Conclusion: Considering the lower incidence of amenorrhea and spotting in cyclofem users, encouraging eligible clients to use the cyclofem contraceptive method is recommended. Also these users are recommended to carefully control their body weight and blood pressure.

Abstract
Background: Measurement of mean arterial blood pressure is better predictive factor for pregnancy-induced hypertension than measurement of the systolic and diastolic blood pressure or systolic blood pressure. According to the theory of “protective effect of fish oil supplementation on pregnancy-induced hypertension “and the importance of blood pressure control in pregnancy, the present study was conducted to investigate the effect of fish oil supplementation in pregnancy on mean arterial blood pressure. Materials and Methods: In this clinical trial study, 120 healthy pregnant women were randomly divided into two groups of 60 persons. Same prenatal care was performed for both groups and the intervention group was received Salmon fish oil capsule 1000 mg/day, from 16th week to the end of the pregnancy. Systolic and diastolic blood pressure were measured in both groups once every four weeks up to 28th week, every 2 weeks from 28th till 36th week and once every week up to the end of pregnancy. Mean arterial blood pressure was calculated and all gathering data was analyzed with T test and Mann-Whitney test. Results: Mean arterial blood pressure in the intervention and control group was 80.76±5.50 and 78.46±4.50 mmHg which was not significantly different (p>0.05). Conclusion: The results showed that adding fish oil supplements to the diet of pregnant mothers had no significant effect on mean arterial blood pressure.

Abstract
Background: Rheumatoid arthritis is an inflammatory disease. Hypertension could occur as a result of chronic inflammation in RA patients. Some evidence demonstrates anti-inflammatory effects of alpha-lipoic acid in inflammatory diseases. However, a limited number of studies have evaluated the effects of alpha-lipoic acid in rheumatoid arthritis. Therefore, the current study was designed to investigate the effects of alpha-lipoic acid supplementation on blood pressure and some inflammatory factors.
Materials and Methods: The present study was a randomized, double-blinded, placebo-controlled clinical trial in which 70 female patients aged 20–50 years were randomized to two groups to receive either alpha-lipoic acid (1200 mg/day) or placebo. The intervention duration was 8 weeks. Systolic and diastolic blood pressures were measured before and after the supplementation period. Also, C-reactive protein (CRP) and interleukin-6 (IL-6) were measured. Statistical analysis was done using SPSS13 software.
Results: 65 RA patients completed the trial. Systolic and diastolic blood pressure in alpha-lipoic acid group was significantly decreased in comparison with placebo group (p<0.05). But, CRP and IL-6 serum levels did not indicate any significant within- and between group changes.
Conclusion: In the present study, alpha-lipoic acid supplementation resulted in significant blood pressure reduction in rheumatoid arthritis participants.

Abstract
Background and Aim: Pregnancy and exercise training are associated with changes in the cardiovascular anatomy and physiology. There is a few studies on this issue in Iran. In this regard, the aim of this study is to assess the effect of a combined exercise training program on blood pressure and heart rate variability of pregnant women.
Methods & Materials: This randomized clinical trial was conducted in Shahid Akbarabadi Hospital in Tehran, Iran in 2019. Participants were 10 healthy pregnant women with a gestational age of 24-26 weeks in the interventional group and 10 healthy pregnant women in the control group. The interventional group received 8 weeks of combined exercise training at moderate intensity. The blood pressure measurement, electrocardiogram and aerobic and resistant exercise tests of samples were performed before and after training. AST3000 Avicenna software was used to analyze the heart rate variability parameters, and for statistical analysis, paired and independent t-tests, Mann Whitney U, and Wilcoxon tests were used.
Ethical Considerations: This study with registered clinical trial code IRCT20190227042856N1 was approved by the Research Ethics Committee of Islamic Azad University of Science and Research Branch in Tehran, Iran (code: IR.IAU.SRB.REC.1397.101).
Results: The mean systolic and diastolic blood pressure levels were lower in the interventional group by the 34th week of pregnancy compared to the control group (P<0.05). The mean of time-domain parameters in the interventional group were higher by the 34th week of pregnancy compared to the control group (P<0.05).
Conclusion: Combined exercise training can improve autonomic and parasympathetic nervous systems in pregnant women.

Abstract
Background and Aim Preeclampsia is a common complication of the second half of pregnancy. Sleep disorders can cause high blood pressure by causing oxidative stress and endothelial dysfunction. Therefore, the present study was performed to determine the relationship between sleep disorders and preeclampsia.
Methods & Materials This is a case-control study that was performed on 240 women referred to the affiliated university hospitals in Mashhad. Sampling was performed in the case group of hospitalized women with a definite diagnosis of preeclampsia (n=90) and in the control group (n=150) among pregnant women without preeclampsia referred to the obstetrics clinic. Data collection tools included demographic information questionnaire and gynecological/obstetric records, Pittsburgh Sleep Quality Questionnaire and clinical evaluation form to determine the symptoms and severity of preeclampsia. Data analysis was performed using SPSS statistical software (version 22) and Mann-Whitney, Chi-square and Fisher tests. A P value of less than 0.05 was considered significant.
Ethical Considerations The present paper is the result of a research project approved by the Vice-Chancellor for Research of Mashhad University of Medical Sciences (Code: IR.MUMS.NURSE.REC.1397.042).
Results The mean amount of real sleep at night in the group of healthy individuals (8.4±2.3) was significantly higher than patients (8.0±2.2) (P=0.028). In terms of loud snoring, waking up in the middle of the night was most frequent in the affected group (P<0.001). There was a statistically significant difference between the two groups in terms of sleep quality score level (P<0.001) based on logistic regression test in women with severe sleep problems at risk of preeclampsia (P<0.001, 95% CI 2.9-42.2, OR: 11/11) (11/11) was equal compared to healthy women.
Conclusion The present study showed that sleep disorders in pregnancy are associated with an increased risk of preeclampsia.
