Turkish day-to-day impact of vaginal aging questionnaire: reliability, validity and relationship with pelvic floor distress.

INTRODUCTION AND HYPOTHESIS: We aimed to translate the Day-to-Day Impact of Vaginal Aging (DIVA) Questionnaire into Turkish, adapt it culturally, and investigate its reliability and validity. Another aim of the study was to examine the relationship between the impacts of vaginal symptoms and pelvic floor symptoms on quality of life (QoL). We hypothesized primarily that the the Turkish DIVA had good internal consistency, test-retest reliability and construct and criterion validity. Our secondary hypothesis was that the effects of vaginal symptoms and pelvic floor symptoms on QoL would be positively related. METHODS: A total of 218 postmenopausal women were included. In the reliability analyses, Cronbach α coefficients, item-total correlation coefficients and intraclass correlation coefficients (ICCs) were used. Construct validity was investigated with explanatory and confirmatory factor analyses. Criterion validity and the relationship between the effects of vaginal symptoms and pelvic floor symptoms were examined by Pearson correlation analysis. RESULTS: While the Cronbach's alpha coefficients ranged between 0.87 and 0.96, the item-total score correlation coefficients were 0.60-0.91. ICCs ranged from 0.90 to 0.99. It was found with confirmatory factor analysis that the model fit the data. Moderate-strong correlations (r = 0.47-0.73) were observed between DIVA scores and the scores of other scales (p < 0.001). CONCLUSIONS: The Turkish DIVA is a reliable and valid tool that comprehensively evaluates the impact of vaginal symptoms on women's QoL. The positive relationship between the impacts of vaginal and pelvic floor symptoms on functionality and well-being of women suggests a holistic view in pelvic health care.

Effect of Chemical Pre-treatments on Bioethanol Production from Chlorella minutissima.

In recent years, algal bioethanol production comes into prominence as a trend towards sustainable development. Due to being sustainable energy source and environmental friendly, bioethanol production from algae is becoming increasingly popular all over the world. However, yield of bioethanol production from algae is lower than first generation feedstock's currently, and needs to be improved. In order to increase bioethanol yield, pre-treatments should be performed as cell disruption process on algal biomass. For this reason, researchers investigate the most appropriate pre-treatment method and its parameters for high yield bioethanol production from algae. In this study, cultivated Chlorella minutissima was utilized for bioethanol production. Effects of pre-treatment method (dilute acid and alkaline), chemical concentration, pre-treatment temperature and pre-treatment time on bioethanol yield were investigated. It was found that, the highest bioethanol yield was obtained as 18.52% with acid pre-treatment at pre-treatment temperature of 100 °C and pre-treatment time of 60 minutes.
