Background Human instinctively desire to have offspring. Infertility can cause painful emotional experiences throughout the life mainly known as quality of life impairment. This study aimed to investigate the impact of infertility on a woman’s quality of life. Methods A number of 180 infertile and 540 fertile women participated in this matched case-control study. The cases were selected through a combination of multistage stratified and cluster sampling methods. For each infertile woman three fertile women were randomly selected. The data gathering instrument consisted of demographic variables and the WHOQOL-BREF questionnaire. Data collection was conducted through interview with participants. The multivariate marginal model and SPSS software 21 were used for data analyses with a significance level of 0.05. Results The results of the multivariate modeling show infertility can potentially affect various aspects of women’s quality of life such as physical health ( p <  0.001), mental health (p <  0.001), social health (p <  0.001) and the total score of quality of life (p <  0.001) significantly. Conclusion An infertile woman practice a relatively lower scores in QOL sub-scales of mental, physical and environmental health; while they experience a higher social health score than a fertile woman.

There is limited evidence that the gestational age at delivery may influence the risk of maternal breast cancer. While extreme prematurity has been suggested to increase the risk, there seems to be no study available so far that investigates the due effects of a late delivery. This research aimed to identify the impact of both preterm and late deliveries on the risk of maternal breast cancer within a period of 5 years after birth. Our dataset was created by linking data from the Nevada Cancer Registry database (1995-2008) and the birth certificates issued by the Nevada State Health Division (1994-2003). The study cohort consisted of 213,250 women who gave birth from January 1, 1994 to December 31, 2003. We performed a nested population-based case-control study on 126 Nevada mothers with a first lifetime breast cancer diagnosed from January 1, 1995 through December 31, 2003, and 504 Nevada cancer-free mothers. Women with pregnancies who progressed beyond 40 weeks of gestation were at a significantly lower risk of developing breast cancer for the 5-year period following a delivery, when compared to women who delivered at 37-40 weeks of gestation (OR: 0.33, 95% CI: 0.11-0.92) in a multivariate model. Additional pregnancy characteristics did not significantly predict the risk of maternal breast cancer. Pregnancies that extended beyond 40 weeks of gestation were strongly associated with a lower likelihood of premenopausal breast cancer. Biological plausibility for this association may correspond to the fact that as pregnancy develops into more advanced stages, mammary cells have more time to attain complete differentiation and maturation; a process that starts early in the third trimester.

<b><i>Objective:</i></b> Complementary therapies have been increasingly used for the prevention and treatment of migraine so that there is a need for studies in this setting. This study sought to determine the effects of basil essential oil on the severity and frequency of migraine attack headaches. <b><i>Methods:</i></b> A triple-blind clinical trial study was performed on 144 patients diagnosed with migraine. Patients were randomly allocated by a stratified method to four groups of 36 titled basil essential oil 2, 4, 6%, and placebo groups. Medications were used topically every 8 h for 3 successive months. In addition, each individual received 325 mg of acetaminophen every 12 h. The severity and frequency of migraine attacks were measured prior to the study, at weeks 2, 4, 8, and 12. The visual analog scale was used to measure pain intensity. The marginal model and generalized estimation equations were used to compare changes in the intensity and frequency of pain over time. <b><i>Results:</i></b> The interaction of the dose and time factors was significant on both pain intensity (<i>p</i> &#x3c; 0.001) and frequency of attack (<i>p</i> &#x3c; 0.001). The odds ratio of higher pain intensity and rate ratio of higher frequency of attack in the intervention groups compared to the placebo group were decreased over the study time. <b><i>Conclusion:</i></b> Time lapse and higher doses of basil essential oil would reduce both the intensity and frequency of migraine attacks.

Backgroundbreakfast elimination as well as consumption of low-value snacks is ever increasing among adolescents. This study sought to explain the dimensions of social support for breakfast and healthy snacks among students.MethodsA qualitative research was conducted in Isfahan, Tehran, and Khorramabad, Iran high schools in 2017–18. Data were obtained from five focus group discussions and 35 in-depth interviews as well as semi-structured interviews with students of both sex, parents and school authorities. The data simultaneously analyzed using conventional content analysis in three stages including preparation, organization, and reporting. Prolonged engagement, maximum variation of sampling and member check were the enrichment factors of the research.ResultsThree main categories emerged. First, family supports with sub- categories of family in the school programs as well as mother-sponsored support and family life patterns. Second, school supports with sub- categories of instrumental and informational support. And third, support of other community organizations with sub- categories of intra-department coordination and mass media.ConclusionThe concepts emerging in the present study develop multilevel ecological strategies to promote nutritional health including family, school, and community organizations such as school renovations, municipalities, police, education, and mass media to promote healthy breakfast and snack behavior are applicable for students.
