Five hundred milligrams per day quercetin supplementation for 8 weeks resulted in significant improvements in clinical symptoms, disease activity, hs-TNFα, and HAQ in women with RA.

It is concluded that in contrast to conventional yogurt, daily consumption of probiotic yogurt for 9 weeks maintains serum insulin levels and might help pregnant women prevent developing insulin resistance.

Parents and school staff play important roles in promoting children's oral health. Our study goals were to investigate whether an intervention targeting parents and school staff can improve the oral-health behavior and oral-health status of schoolchildren. Three-hundred and ninety-two schoolchildren in six schools in Tehran participated in a group randomized trial from September 2010 to March 2011. Schools were randomly allocated into three groups: comprehensive, student, and control. Intervention in the comprehensive group consisted of strategies to encourage children, their parents, and school staff to increase the frequency of toothbrushing and flossing. In the student group, the intervention targeted only children. The control group received no intervention. The primary outcome was change in oral-health behaviors (brushing and flossing), while the secondary outcomes were changes in oral hygiene and Community Periodontal indices and in Health Belief Model components. Multilevel modeling was employed for data analyses. Students who were in the comprehensive intervention group brushed and flossed significantly more frequently compared with those in the student intervention group. Although students' gingival health improved significantly in the comprehensive intervention group, such significant improvement was not seen in the student group. In conclusion, promising results are seen when the oral-health education targets both school and home settings.

as job insecurity, skill discretion, job strain and social support play an important role in maintaining work ability. A positive combination of "psychosocial characteristics" of the job with "individual resources" can promote work ability in such occupations. Work ability is a multifaceted and multidetermined concept not only associated with health but also with competence, values, the working environment and social relations 1) . The level of work ability in the working population can predict both future permanent disability and duration of sick leave absences 2,3) . So far, a large variety of studies have addressed determinants of work ability in occupational populations with predominantly physical demands at work. From these studies, it is known that WAI in such occupations is influenced by various factors like health problems, lifestyles, individual characteristics and many work-related risk factors [4][5][6] . Among the work-related risk factors, Alavinia 7) showed a strong association between psychosocial and physical factors and impairment of work ability.However, a few researches identified a number of psychosocial factors in the work environment as risk factors for work ability. Tuomi 8,9) showed that dissatisfaction with supervisor's attitude, lack of freedom, decrease in recognition and esteem and role ambiguities at work were associated with impaired work ability among municipal workers. Similarly, lack of support at work, poor possibilities to control one's own work and poor management were also associated with a lower WAI among construction workers and home care workers 7,10) . Although the relationship between work ability and some psychosocial factors has been described in In recent decades, work ability index (WAI) has been a common practical tool to measure individuals' work ability in many European, Asian and South American countries. However, there is no study concerning work ability in Iran. The aim of this study was to determine the work ability index in an Iranian petrochemical job setting and to examine its relationship with psychosocial factors. Methods: A cross-sectional study was conducted among 420 male workers in various occupations. Work ability was evaluated using the WAI questionnaire developed by FIOH; the Job content questionnaire (JCQ) was used to assess psychosocial factors. Results: The mean WAI score was 39.1 (SD=5.7) among workers in the studied petrochemical industry. Multiple linear regression analysis revealed a significant association between mean WAI score and age, job tenure, educational level, rest and sleep status and vocational education. Moreover, the results showed that skill discretion, coworker support and supervisor support were positively associated with the mean WAI score. On the other hand, it was inversely associated with job demands, job strain and job insecurity. Conclusions: This study was the first research to determine WAI in an important industry in Iran. Overall, work ability was in the "Good" category among the workers in the studied field. On the...

BackgroundMuch evidence consistent with the Marital Discord Model of Depression (MDMD) suggests that marital discord is associated with depression, but no studies examine the relationship between marital satisfaction and depression at the dyadic level in infertile couples. This study examined the effect of actors’ and partners’ marital satisfaction on depressive symptoms in husband-wife dyads with infertility using an innovative dyadic analysis approach, the Actor–Partner Interdependence Model (APIM).MethodsIn this cross-sectional study, the sample comprised of 141 infertile couples in the evaluation phase of treatment. We collected data in a referral infertility center in Tehran, Iran between February and May 2017. Marital satisfaction and depression were measured using ENRICH marital satisfaction scale and Hospital Anxiety and Depression Scale, respectively, before starting the treatment. Dyadic analysis applying the APIM was used. In this study, actor effect is the impact of a person’s marital satisfaction on his/her own depression. Partner effect is the impact of a person’s marital satisfaction on his/her partner’s depression.ResultsThe APIM analysis revealed that both men and women’s marital satisfaction excreted an actor effect on their own depression (β = − 0.412, P < 0.001; β = − 0.263, P = 0.002, respectively). Furthermore, men’s marital satisfaction exerted a significant partner effect on their wives’ depression symptoms (β = − 0.170, p = 0.047). However, the wives’ marital satisfaction was not related to their husbands’ depressive symptoms (β = − 0.028, P = 0.735).ConclusionsThe findings support that the MDMD is a valid theoretical model for the conceptualization of marital satisfaction and depressive symptoms among infertile couples and suggest that interventions to reduce depressive symptoms should include both men and women.
