Marriage and choice of spouse is one of the most important events of human life which affect not only the physical but also mental health of the individual. It is certain that any problem that arises in the family, the losses will concern the total structure and cultural value system of the society. Unfortunately, young couples do not allocate particular time and energy to preparedness to establish relationship and consequently experience the considerable amount of conflict in early years of marital life. The aim of this study is to investigate the effectiveness of choice theory education on increasing self-differentiation and intimacy in married couples. In thisinterventional study, 30 married couples of students (n=60) were selected and allocated randomly to case (15 couples) and control (15 couples) groups. Differentiation of Self-Inventory (DSI) and Marital Intimacy (MIQ) questionnaires were completed by students. The control group received no training. Intervention included 10 sessions of choice theory education. results showed that choice theory education by grouping method is effective in increasing the self-differentiation of married students, in which the mean score of self-differentiation in case group increased from 170.2±19.2 to 191.8±10.1. Also, the effect of intervention on increasing the couples’ marital intimacy was not significant. Result of this research confirmed the effectiveness of choice theory education in increasing the self- differentiation, so regarding the cultural and social transition and also the increasing need of incipient married youth, it is recommended that education of these skills will be concerned in the academic and training centers.

Apart from glucose، insulin release is stimulated or suppressed by some hormones and neural signs. Ghrelin is a gut hormone that stimulates growth hormone (GH) secretion، and recent studies have suggested its role in insulin secretion. The objective of this study was to determine baseline insulin’s relationship to ghrelin and GH concentration in asthma males. In this study، we measured the baseline blood levels of serum ghrelin and GH in adult obese males with mild to moderate asthma and assessed their relationship with serum insulin and pancreatic beta- cell function. Pearson correlation analysis was used to determine the relationship between insulin and other variables. A significant negative correlation was found between fasting serum insulin and both ghrelin and GH concentration. In addition، there was a significant negative correlation between the beta- cell function and both serum ghrelin and GH (P<0. 05). Our study findings demonstrated that in adult asthma patients، an increase in serum ghrelin and GH is accompanied by a decrease in serum insulin secretion، and the measuring of serum ghrelin or GH is a predictor of blood insulin level in these patients.

Problems with sexual function have been reported to occur commonly in women with pelvic organ prolapsed. The aim of this study was to assess the sexual function in women who underwent surgical treatment of pelvic organ prolapsed. This is a before after study in which fifty legible patients suffering from pelvic organ prolapsed were assessed for sexual function) before surgery and three month after surgery. The data were collected through a demographic questionnaire، midwifery history and Female Sexual Function Index (FSFI). The collected data were analyzed through paired T-test، chi-square and multiple linear regressions. Mean FSFI total score improved from baseline 19±10. 8 to 23. 8±5. 2 (P=0. 01). Domain scores of desire (2. 7±1. 2 vs. 3. 4±0. 8)، arousal (2. 6±1. 7 vs. 3. 6±0. 8)، lubrication (3. 8±2. 3 vs. 4. 7±1. 1)، orgasm (3. 2±2. 1 vs. 4±1. 05)، satisfaction (3. 4±1. 8 vs. 4. 1±1. 3) and pain (3. 3±2. 3 vs. 4. 2±1. 1) also significantly increased (P<0. 05). Sexuality improved following surgery for either prolapsed or urinary incontinence، or both. It’s important to counsel women with POP for undergoing surgery.

Health organizations regard behavior as a key foundation of today’s common diseases and health problems. This study was designed and implemented in Qazvin industrial Town in the first half of 2009 in order to assess the impact of educational interventions based on theory of planned behavior on improving safety behavior of porcelain industry workers. 75 workers in each intervention and control groups participated in a quasi-experimental randomized controlled trial. Demographic information and data related to TPB constructs, knowledge and safety performance were collected through a self-administered questionnaire and the safe operation checklist 3 months and 6 months after the intervention. Panel of experts, Cronbach's alpha coefficient, test-retest reliability coefficient and Kappa coefficient were used to confirm the psychometric properties of the tools. Educational intervention accompanied by booklets was applied in the form of four 45 to 60 minute training classes attended by 8 to 15 workers in each class through group discussion method focusing on theory of planned behavior constructs. The Data were analyzed by Repeated measure ANOVA. The average age of participants was 31± 7.4 years, and 65 percent of participants were male. Before the intervention, there was no significant difference between the two groups in terms of demographics and the study main variables. After training, however, results showed significant changes of mean scores of attitude (from 17.17±5.37 to 25.6±4.45, P<0.001), subjective norms (from 4.73±2.05 to 6.95±1.49, P<0.05), perceived behavior control (from2.72±1.07 to 6.89±1.6, P<0.001), intention (from 7.97±3.61±10.86±2.76, P<0.05), self report behavior (from 2.20±1.01 to 3.6±1.22), knowledge (from 6.96±1.84 to 9.87±1.47) and safety behavior (from 6.32±1.45 to 8.5±2.11, P<0.05) in the experimental group, while no significant changes in these variables was observed in the control group. The research results show that TBP educational intervention is able to change workers’ awareness, attitude, subjective norm and perceived behavior control towards unsafe behavior and improve their safety performance.
