Introduction: A variety of maladies, sometimes disabling, beset many ovulatory women in a recurrent manner during the luteal phase of each ovarian cycle. These problems can deteriorate interpersonal relationships and/or interfere with normal activities of life. Present research was performed to evaluate effects of hypericum perforatum for treatment of physical symptoms of premenstrual syndrome.

Materials and Methods: This study was a randomized, double-blind, placebo-controlled, parallel group compassion study performed over two menstrual cycles on student of Tehran University of Medical Sciences and Tehran University. Volunteers underwent a preliminary screening interview, completed Beck questionnaire as a screening test for depression and attended a medical screening visit before being diagnosed as having premenstrual syndrome. Participants administrated hypericum or placebo, 30 drops BD, for two complete cycles. Premenstrual symptoms were evaluated by a daily symptom report form. Data analysis performed by Chi square, Fisher exact, Wilcoxon and t tests.

Results: Premenstrual daily hypericum caused a significant improvement in mean daily score of severity of premenstrual problems compared to placebo (p<0.05). Premenstrual administration of hypericum, 30 drop BD, showed significant advantage over placebo for physical disorders (%49, p=000).

Conclusion: Daily premenstrual administration of hypericum perforatum treats physical symptoms of premenstrual syndrome. It seems that hypericum perforatum can improve symptoms of premenstrual syndrome.

Background & Aim: Several factors have been reported to be influential in development of the premenstrual syndrome. There are no studies available on relationship between premenstrual syndrome with body mass index in Iran. This study aimed to determine this relationship among university students.

Methods & Materials: This was a cross-sectional study conducted on a random sample of 500 students living in the dorms of Arak University of Medical Sciences. The participants had not stress, anxiety and severe depression on the basis of the DASS21. Data were gathered using Social Status Questionnaire, including demographic, menstrual status, reproductive and eating habits and body mass index measurement items. The participants completed the abbreviated form of premenstrual syndrome evaluation within seven days of bleeding up to two days after onset of bleeding for one cycle. Using logistic regression analysis, the association was assessed by adjusting for confounding variables.

Results: A majority of the students had normal BMI (<25) (90.8%). The results showed that the risk of premenstrual syndrome in the participants with high BMI was 2.43 times more than the participants with normal BMI (OR=2.43 CI=8.33-1.66).

Conclusion: High BMI increased the risk of premenstrual syndrome. Interventions to decrease the BMI should be designed and implemented in overweight and obese patients with premenstrual syndrome.

  Background & Aim: The aim of present study was to assess psychometric properties of premenstrual symptoms screening tool (PSST) to provide a fast and appropriate screening tool for women who suffer from severe PMS/PMDD and their clinicians .

  Methods & Materials: It was a cross-sectional study. The study included 404 female students studying at Semnan University who were randomly selected using stratified method. In order to assess psychometric properties, we used the exploratory factor analysis, convergent validity (evaluated by symptom checklist-90-Revised), criterion-related validity (calculated by comparing psychiatrist diagnosis and PSST). Sensitivity and specificity coefficients of optimal cutoff points were calculated by the ROC Curve and construct validity was evaluated by the PSST ability to separate PMS and PMDD groups from healthy group. Reliability was evaluated using the cronbach’s alpha and test-retest method . 

  Results: The p rinciple component analysis revealed that the PSST consists of four factors: interest reduction, interference in functions, physical and neurotic symptoms, and eating and sleep patterns. As an evidence of convergent validity, PSST scores showed significant correlations with the SCL-90-R’s dimensions. Agreement coefficient between psychiatrists and the PSST diagnosis was 0.314 for the PMS and 0.80 for the PMDD. This tool separated the PMS and PMDD groups from healthy group well. Optimal Cutoff point for separating females suffering from PMDD was 2.22. The sensitivity and specificity coefficients were 0.9 and 0.77, respectively. The cronbach’s alpha was 0.91 and the test-retest reliability was 0.56 for the total tool .

  Conclusion: The translated version of the premenstrual symptoms screening tool can be used as a valid tool for Iranian females. This instrument can be useful for rapid screening and identifying women who suffer from severe PMS/PMDD, especially in clinical settings .

Background & Aim: Although mechanical ventilation is a life-saving intervention for many infants with respiratory distress syndrome, it carries potential complications. One of these complications is prolonged duration of mechanical ventilation. More than 15 days of mechanical ventilation is associated with increased risk of cerebral palsy and attention deficit hyperactivity disorder among extremely low birth weight infants. The current study aimed to determine the relationships between the length of mechanical ventilation and its related factors in neonates with respiratory distress syndrome.

Methods & Materials: In this analytical study, a convenience sample of 60 premature infants of 33 weeks’ gestation or less with respiratory distress syndrome was recruited from three hospitals (Mahdieh, Mofid, and Imam Hossein) affiliated to Shahid Beheshti University of Medical Sciences in 2014-2015. Then, factors related to the length of mechanical ventilation such as sex, type of birth, birth weight, gestational age, Apgar score at the first minute, Apgar score at the fifth minute were assessed. The data were analyzed using descriptive statistics, Pearson correlation, independent t-test, and multiple regression analysis on SPSS software v.20.

Results: The mean gestational age was 30.62±1.8 weeks and the mean weight of infants was 1510.33±390.940 grams. The mean length of mechanical ventilation was 3.58±2.97 days. There  were not any correlations between sex, type of birth and the length of mechanical ventilation (P>0.05). Gestational age and weight were significantly correlated to the length of mechanical ventilation (P<0.001). But in adjusted analysis using multiple regression, only gestational age remained a significant factor related to the length of mechanical ventilation (P<0.05).

Conclusion: The results of the current study revealed that among the studied factors, only gestational age was a factor affecting the length of mechanical ventilation.

Background & Aim: Restless leg syndrome (RLS) is one of the common complications in patients under treatment with hemodialysis. Progressive muscle relaxation is a method which has been designed for reducing patients’ stress, pain and anxiety. The present study aimed to determine the effect of progressive muscle relaxation on the severity of RLS in hemodialysis patients.

Methods & Materials: In this quasi-experimental study (IRCT2015102824769N1), 74 hemodialysis patients were selected by convenience sampling method and divided into intervention and control groups based on records numbers. The intervention group was trained in progressive muscle relaxation technique in two half-hour sessions and they were asked to practice it twice a day for one month. RLS severity was measured using the standardized RLS questionnaire. Data were analyzed by descriptive and inferential statistical tests (independent and paired t-test, analysis of co-variance) using SPSS software version 23.

Results: There was no significant difference in the distribution of variables in the intervention and control group before intervention (P>0.05). Before the intervention, RLS severity score was 28.24±7.33 in the intervention group and 25.57±9.85 in the control group (P=0.189). After the intervention, the score for the intervention group was reduced to 10.67±5.66 (P>0.001) while there was no significant change in the control group after the intervention (26.16±9.69). Also, a significant difference was observed between the two groups in the mean score of RLS severity after removing the effect of RLS severity on pretest (P>0.0001).

Conclusion: The use of progressive muscle relaxation technique reduces RLS severity in patients under treatment with hemodialysis. Therefore, this technique is recommended to be used as one of the non-pharmacological methods to improve RLS in these patients.

Background & Aim: Improving and modifying lifestyle is necessary for health maintenance and promotion. Modification of lifestyle can have an important role in the long-term health of women with Poly Cystic Ovarian Syndrome (PCOS). Therefore, this study aimed to determine the status of health promoting lifestyle and its socio-demographic predictors in women with PCOS.

Methods & Materials: This analytical descriptive cross-sectional study was conducted on 174 women with PCOS referred to gynecology and infertility clinics in Urmia-Iran, in 2015. The data were collected through the socio-demographic and Health Promoting Lifestyle Profile questionnaires. Descriptive statistics, independent t-test, one-way analysis of variance and multivariate linear regression were used to analyze the data through SPSS software version 21.

Results: The mean (standard deviation) of total score of the health promoting lifestyle was 2.2 (0.3) out of 4. The highest mean score was in nutrition subscale [2.9 (0.5)] and the lowest mean score was in the subscale of stress control [1.2 (0.5)]. Based on the multivariate linear regression model, the variables of BMI, spouse’s education level, the first supporter and menstrual bleeding amount were predictors of the health promoting lifestyle in women with PCOS.

Conclusion: Considering that the mean of total score of the health promoting lifestyle and some of its subscales were in the middle of the range of possible scores, it is necessary that besides other therapies, the improvement of health promoting lifestyle in women with PCOS, according to the influencing socio-demographic determinants, be on the agenda of health providers.

Background & Aim: Acute coronary syndrome is the most common cardiovascular disorder. Hope and optimism lead to adaptation to and moderation of the damaging effects of depressed mood on the outcome of this disorder. The aim of this study was to determine the effect of positive psychology-based audio messages on hope and optimism among patients with acute coronary syndrome.
Methods & Materials: In this randomized controlled clinical trial, 84 patients with acute coronary syndrome were assigned to either intervention or control groups in Shahrekord educational hospitals in 2017-2018. The intervention group received audio messages based on positive psychology and cardiovascular self-care, and control group only received self-care messages in two hospital admissions and six weeks after discharge. The Life Orientation Test-Revised and the Snyder's Hope Scale were completed before the intervention, at the discharge time, one week and six weeks after the intervention. Data were analyzed by c² and Fisher exact tests and analysis of variance using the SPSS software version 20.
Results: No significant difference is observed in the mean score of hope before the intervention and at the discharge time. However, the mean score of hope was significantly different between the two groups, one week and six weeks after the intervention (P<0.001). There was no significant difference in the mean score of optimism between the two groups before the intervention. Nevertheless, difference in the mean score of optimism was significant at the discharge time (P=0.027), one week and six weeks after the intervention (P<0.001).
Conclusion: Positive psychology-based messages improve hope and optimism in patients with acute coronary syndrome. Therefore, this intervention is recommended along with other treatments.

Background & Aim: Irritable bowel syndrome (IBS) is a functional bowel disorder characterized by abdominal pain or discomfort and altered bowel habits and can significantly impair quality of life (QOL). Personality has an important effect on health-related quality of life. However, its effect on the quality of life of patients with irritable bowel syndrome is yet unknown. The present study was conducted with the aim of determining the relationship of quality of life with neuroticism, extroversion, conscientiousness, and their subcomponents in patients with irritable bowel syndrome.
Methods & Materials: This is a descriptive-correlational study. The studied population was IBS patients referred to a private gastrointestinal clinic in Tehran in 2021.The sample size was 223, and subjects were selected through the consecutive sampling method. The data were collected using NEO Five-Factor Inventory (NEO-FFI) and the Irritable Bowel Syndrome Quality Of Life (IBS-QOL) questionnaire. To analyze the data, descriptive statistics and regression analysis were used at the confidence level of 95% through the SPSS software version 24.
Results: The mean score of IBS-QOL was 57.68±20.55. Regression analysis suggested that personality subcomponents such as self-reproach (β=-0.376, P<0.001) and positive affect (β=0.160, P=0.020) were the most important predictors of the score of IBS-QOL. The scores of self-reproach and positive affect explained 22.6% of the variance score of IBS-QOL.
Conclusion: The results of current study suggested that the scores of some personality subcomponents including self-reproach and positive affect significantly predict the score of IBS-QOL. Hence, it seems that in addition to common pharmaceutical treatments for IBS patients, considering personality subcomponents (particularly self-reproach and positive affect) is effective in improving these patients’ quality of life.

Background & Aim: Chest pain is one of the main symptoms of acute coronary syndrome, and sleep disorders are among common problems in these patients. The aim of this study was to determine the effect of Curcuma Longa on chest pain and sleep quality in patients with acute coronary syndrome.
Methods & Materials: This triple-blind clinical trial was conducted on 270 patients in the Coronary Care Unit of Kowsar Hospital in Semnan, with random allocation to three groups (intervention, placebo and control) in 2020-2021. The intervention group received 500 mg of Curcuma Longa tablets and the placebo group received 500 mg of starch, Oisel and lactose tablets at 9 a.m. after breakfast once a day for 3 days. The control group received daily interventions. Chest pain was assessed using the pain assessment tool before the intervention and half an hour after the intervention for 3 consecutive days. Sleep quality was evaluated by the standardized sleep quality questionnaire of Saint Mary's Hospital in the morning of the first day before the intervention and in the morning of the second and third days after the intervention.
Results: There was no significant difference in the average reduction of chest pain intensity from the first to the third day between the groups (P>0.05). But there was a significant difference in the chest pain intensity within the intervention, placebo and control groups (P<0.001), and the average chest pain intensity on the second day compared to the first day of hospitalization decreased in three groups (P<0.001). However, the decrease in chest pain intensity on the third day compared to the second day of hospitalization was not significant in the three groups (P>0.05). The average score of sleep quality before the intervention in the intervention group was higher than that of in the placebo group (P=0.021), but on the second and third days of the intervention, it was lower in the intervention group compared to the placebo (P<0.001) and control groups (P<0.001).
Conclusion: The results showed that Curcuma Longa did not have a significant effect on chest pain in the patients with acute coronary syndrome, but it improved the quality of sleep. Therefore, Curcuma Longa can be used to improve the sleep quality of these patients.
