Objective Gestational diabetes mellitus (GDM) is the most prevalent medical complication in pregnancy. Early diagnosis of GDM can influence maternal/neonatal outcomes. To assess the association between platelet and blood inflammatory indices and the risk of GDM occurrence using the complete blood count (CBC) test. We also aimed to determine the sensitivity of each parameter for an early screening of this disorder during pregnancy. Methods This case-control study included 2 groups of 110 pregnant women with and without GDM. The women in each group were compared after the routine screening for GDM and after the CBC test at 24-28 weeks' gestation after being matched according to the inclusion criteria. Data were analyzed using SPSS version 16 and Medcalc version 14.8.1 software. Results There were statistically significant intergroup differences in white blood cell (WBC) count, platelet count, mean platelet volume (MPV), plateletcrit (PCT), MPV to platelet ratio, platelet to lymphocyte ratio, and Rh values. The values of lymphocyte count, neutrophil count, neutrophil to lymphocyte ratio, and blood group were not significantly different between groups. The logistic regression analysis showed the predictive values of WBC, platelet, MPV, and PCT in GDM. According to the receiver operating characteristic curve for all 3 variables, the level below the PCT chart was more than that of the others. Conclusion Increasing platelet and inflammatory indices on the CBC test in the second trimester of pregnancy seemed to be associated with the probability of GDM occurrence.

Background: Education and counseling during marriage is an opportunity to raise some issues needed by couples on the verge of marriage. This study was conducted with the aim of improving reproductive and sexual health literacy of couples on the verge of marriage. Methods: The current study was participatory action research conducted based on the Find.Organize.Clarify.Understand.Select-Plan.Do.Check.Act (FOCUS-PDCA) model in 9 steps during 2019-2020 in the city of Bandar Abbas. According to the steps of this model, a qualitative study was conducted to examine the views of service providers and couples on the verge of marriage regarding the strengths and weaknesses of the training content and the way of providing the training. Then, the process of providing service to couples was designed, implemented, and evaluated based on the results. The Reproductive Health Literacy Scale and the Service Quality (SERVQUAL) Questionnaire were used to evaluate the interventions. Data were analyzed by SPSS version 26. A significance level of less than 0.05 was considered. Results: The mean age of women and men participating in the quantitative part of the study was 21 ± 5 and 25.84 ± 3.9 years, respectively, which was similar to their counterparts in this part of the study, and the difference in the mean scores of reproductive health literacy before and after the changes in the program showed a significant difference (p>0.001). The study results showed that, except for the understanding dimension, most participants were at an insufficient level in other dimensions of reproductive health literacy. The result of measuring the satisfaction of service recipients indicated good satisfaction in the two dimensions of warranty and accountability, and there was a gap in empathy, assurance, and tangibility dimensions, which the biggest gap was related to the empathy dimension. Conclusion: The changes made in improving the reproductive health literacy of couples were effective, which can be taken into consideration based on the added items in the current program of providing educational services in marriage preparation classes for couples.
