Purpose: This study was conducted with the aim of determine the effect of acceptance and commitment therapy on sleep quality and blood pressure of elderly with insomnia. Methodology: The present study was a quasi-experimental with pre-test, post-test and two-month follow-up with a control group. The study population was the elderly with insomnia at the Shiraz Visual Elderly Day Care Center in 2019, from which 40 people were selected by simple random sampling according to the inclusion criteria and randomly replaced in two equal groups. The experimental group received 8 sessions of 90 minutes (two sessions per week) of acceptance and commitment and the control group did not receive training. Data were collected using Pittsburgh Sleep Quality Index (Boise et al. 1989) and blood pressure monitor and analyzed by chi-square, repeated measures variance analysis and Bonferroni post hoc test in SPSS-23 software version 23. Findings: The results showed that the experimental and control groups did not differ significantly in terms of gender, education and marriage (P>0.05). Also, acceptance and commitment treatment improved sleep quality and systolic blood pressure in the elderly with insomnia (P<0.05), but had no significant effect on their diastolic blood pressure (P>0.05) and the results were maintained in the follow-up phase. Conclusion: According to the results, planning is necessary to use the acceptance and commitment therapy method in the field of elderly to improve sleep quality and systolic blood pressure. Therefore, health professionals and therapists can use acceptance and commitment therapy along with other therapies methods to improve sleep quality and systolic blood pressure Manuscript profile

Carbamazepine is used as an anticonvulsant drug in the treatment of simple slight convulsion and generalized tonic-clonic, trigeminal neuralgia, and also as preventive agent in manic depressive. Carbamazepine reduces synaptic transmission by prolonging the inactivity of cellular sodium-potassium pump. Considering the clinical use of carbamazepine, the current study aimed to evaluate its cardiac effects in dogs. In this experimental-interventional study, fourteen native 1.5-2 years old female mixed breed dogs were procured and after laboratory testing and physical examination to ensure their general health status, they were divided into treatment and control groups (7 dogs in each group). On day zero, before drug administration, the electrocardiogram, echocardiogram and blood pressure was recorded. Both groups were maintained in the same conditions and carbamazepine was given orally to the treatment group for 7 days (with a dose of 8 mg/kg). After completing the administration period, the electrocardiogram, echocardiogram and blood pressure was obtained once again and the data were analyzed by one-way ANOVA. Blood pressure was significantly reduced in the treatment group (p < /em><0.05). Significant changes were also induced by carbamazepine in the dogs’ electrocardiogram and echocardiogram (p < /em><0.05). According to the results of the current study, it was found that carbamazepine could decrease blood pressure and induce notable alterations in the electrocardiogram and echocardiogram of dogs.

High blood pressure is one of the risk factors for coronary heart disease, which causes severe damage to the body. A timely diagnosis of blood pressure disease can protect a person from the complications of this disease. A noninvasive method for measuring blood pressure is oscillometric. Accordingly, the blood pressure is estimated by measuring the oscillations created by the opposition of the arterial pressure and the pressure of the cuff wrapped around the arm. In this research, the main goal is to create a software platform for simulating the behavior of veins and cuffs, which can be used to check the performance of different blood pressure measurement algorithms by the Oscillometric method. In this regard, all components including the cuff, and brachial artery, how to extract oscillations from the blood pressure curve, and estimate systolic and diastolic pressures will be modeled. By modeling in MATLAB, the blood pressure measurement can be evaluated without the need for a clinical condition. The output of blood pressure parameters can be obtained by entering the main characteristics of arterial pressure as input. The output of modeling with real samples of 50 measured cases and the accuracy of estimating systolic and diastolic pressures according to two algorithms of maximum oscillation and The maximum/minimum slope were checked considering the actual values. The results of comparing the modeling performance with the measured values indicate that the maximum oscillation algorithm has a better performance than the maximum/minimum slope algorithm. The mean error value in the maximum oscillation algorithm for maximum amplitude pressure, systole, and diastole is 0.64 ± 1.9, 0.82 ± 1.6, and 5.1 ± 6.8, respectively. Manuscript profile

The use of exercise along with herbal supplements is one of the proposed methods for controlling obesity and the complications of obesity, since there are variety of training programs and plant material. However, their exact efficacy is not yet clearly proven. Therefore, the aim of this study was to investigate the effects of aerobic training and green tea supplementation on heart rate and blood pressure among overweight. Thirty overweight healthy female subjects were selected in the age range of 35-25 years. Then, after similarization the groups based on body mass index (BMI) and age, they randomly named to one of three groups: aerobic exercise follow supplementation with green tea group (N=10), green tea supplementation group only (N=10), and exercise group were just aerobics (N=10). Aerobic exercises have been done for 7 weeks in 3 times per week and green tea supplementation was consumed during seven weeks in three times a week in the amount of 2 g after meals. Before and after the intervention period, heart rate, blood pressure and weight of the subjects were measured. One-way ANOVA were used. The results showed that systolic blood pressure follow aerobic training program combined with supplementation of green tea significantly reduced. However, heart rate was reduced in the aerobic exercise group only compared to the green tea supplement group Manuscript profile

Background: Assessment of blood pressure is one of the basics of physical examination that usually is performed by indirect auscultatory method using a mercury manometer. Mercury manometer is the gold standard instrument for blood pressure measurement. Several factors may cause observational error in assessment of blood pressure. Correct and reliable evaluation of blood pressure has a great role in diagnosis and treatment of diseases, so we decided to evaluate the role of auditory perception in measurement of blood pressure after excluding or matching of other interventional factors. Method and materials: seventy specialists in Aria and 22 Bahman hospitals were enrolled in this study. 41 cases were selected randomly using the table of randomized numbers by SPSS software. All cases underwent PTA and tympanometry in order to exclude those with hearing problems. A standard method for assessment of blood pressure was explained for remaining cases and then they recorded the blood pressure of four patients which were presented in a film. Each film was repeated 10 times in a randomized pattern so observers were compared with others and also themselves. Finally, statistical analysis was performed. Results: comparing different observers showed statistically significant differences between observers. Mean interobservers standard error was 9.4 mmHg for systolic blood pressure and 20.5 mmHg for diastolic blood pressure and 16.1 mmHg for mean blood pressure. Comparing observers recordings for each case by themselves, didn’t show any statistically significant difference. Conclusion: according to significant differences between observers, we suggest a new method for assessment of blood pressure that is independent of observers’ auditory perception.   Manuscript profile
