Background & objectives: The spontaneous abortion, loss of the fetus until the twentieth week of pregnancy, is one of the most common medical problems in reproductive age. Approximately 15 to 20 percent of all clinically recognized pregnancies lead to abortion. Failure in pregnancy involves economic costs, physical and mental problems for the family and the society. Recurrent spontaneous abortion is a multifactorial phenomenon and this study analyzed chromosomal abnormalities and the prevalence of consanguineous marriages in parents with recurrent spontaneous abortions in Ardabil province.
Methods: A total of 350 patients with at least two spontaneous abortions were analyzed using GTG-banding cytogenetic technique.
Results:  Parental chromosomal abnormalities were found in 18 cases (10.28% of couples). Most of abnormalities were structural (72.2%). chromosomal aberrations were found in 10 (55.6%) females and 8 (44.4%) males. Translocations were the most common chromosomal abnormalities (55.6 %) diagnosed in this study. Also, there was a significant correlation between recurrent spontaneous abortion due to consanguineous marriage and chromosomal abnormalities (p<0.05).
Conclusion: According to the significant correlation between recurrent spontaneous abortion and chromosomal abnormalities in this study and previous studies, and also the high rate of consanguineous marriages in Ardabil province population, analysis of chromosomal abnormalities is necessary after genetic counseling for both parents with recurrent spontaneous abortions.

Background & objective: The present research has investigated the impact of mental health on the behavioral inhibition and professional judgment of certified accountants with an emphasis on conflict theory.
Methods: In this descriptive-survey research, using Morgan's table, 306 official accountants working in the audit organization and audit institutes of Tehran in 1400, were selected as a sample by a simple random method. To collect data, standard questionnaires including Goldberg and Hiller's mental health, Goldstone and Parker's behavioral inhibition, Knapp, Gul et al.'s professional judgment, and Vahabzadeh's conflict were used. Structural equation model and SMART PLS3 software were used for data analysis.
Results: The research results indicate that the mental health of certified accountants has a negative effect on the conflict between them and the employer and a positive effect on behavioral inhibition and professional judgment of certified accountants. Their behavioral inhibition has a positive effect on professional judgment and a negative effect on the conflict between them and the managers of the receiving companies. Behavioral inhibition and professional judgment of certified accountants play a mediating role in influencing mental health on the conflict between them and the employer. Also, the professional judgment of certified accountants has a mediating role in influencing behavioral inhibition on the conflict between them and business owners.
Conclusion: According to the obtained results, people with higher mental health and stronger behavioral inhibition ability can make more professional judgments and reduce conflicts with others by using their abilities and mental health and managing their behavior. Resolving conflicts will be more successful.
