Abstract
Introduction: Atherosclerotic coronary artery disease is the most common form of heart disease that is associated with high rates of acute myocardial infarction (AMI) and death in young people.
Methods: Given the importance of pregnancy and the postpartum period and the fact that AMI is associated with poor maternal outcomes in postpartum, the present study reports acute myocardial infarction due to dissection of the coronary arteries associated with premature atherosclerosis in late postpartum.
Results: The case was the maternal death of a 34-year-old woman at 42 days postpartum without any history of underlying diseases or symptoms, whose autopsy report read AMI due to coronary artery dissection associated with atherosclerosis.
Conclusions: This report emphasizes the importance of postpartum care and attention to any symptoms witnessed during this period.

Abstract
Introduction: All viral epidemics are a global health problem and a threat to mental health. Medical sciences students are especially prone to mental health disorders and hence could be more vulnerable to the impact of the COVID-19 pandemic. The aim of the study was to evaluation of perceived stress and its related factors in medical students.
Methods: A cross-sectional web-based study was conducted in December 2020 at Islamic Azad University Tabriz Medical sciences. 434 students participated in the study willingly. Socio-demographic characteristics, the level of fear of COVID-19, and perceived stress were collected and analyzed.
Results: The results showed that the mean (SD) of fear of COVID-19 and perceived stress were 20.45 (5.52) and 24.70 (7.90), respectively. There was a significant and positive relationship between fear of COVID-19 and perceived stress in students and this effect was moderate (r = 0.465, P < 0.001, medium). According to the findings, fear of COVID-19 solely has the capacity to explain 24.6% of the changes related to perceived stress in students (β = 0.496, SE = 0.003, P < 0.001). Additionally, multivariate regression analysis revealed that fear of COVID-19, employment state, and academic year capable to explain 25.3% of stress changes in students.
Conclusions: In this study, there was a positive relationship between fear of COVID-19 disease and perceived stress. It is essential to care and plan in order to reduce the negative influence of COVID-19 on mental health and there is a requirement for proper interventions by specialists in order to maintain mental health, particularly for the medical students who are exposed to the disease.

Abstract
Introduction: Nipple problems are the most important reason for early cessation of breastfeeding among mothers. Considering the high prevalence of nipple problems, the present study aimed at evaluating the effect of lanolin cream on the treatment of traumatic nipples.
Methods: This double-blind randomized controlled trial was carried out on 80 breastfeeding mothers that attend health centers and the children hospital of Sanandaj-Iran. The participants were randomly divided into two groups (lanolin and control). The control group receives all supports of the intervention group but their cream contains colorless and odorless, Gelatinous. Nipple pain and trauma were measured using Storr and Champion scale. Analyses were carried out through the Chi-square, Wilcoxon signed-rank test, and U-Mann Whitney by using SPSS software version 13.
Results: There were no significant differences in pain and trauma score before intervention in lanolin and control groups which were (P = 0.336) and (P = 0.21), respectively; but, the results of the study demonstrated that the mean score of pain and trauma in the third, seventh and fourteenth days of study in lanolin group was decreased (P < 0.001). In intragroup comparison, there was a significant difference among the mean pain and trauma scores the four times in the lanolin group.
Conclusions: According to the results of the study, lanolin cream is an effective, simple, and non-invasive technique with no side effects for prevention and treatment in nipple fissures and pain.

Abstract
Introduction: Since hyperactive children are unable to control or dominate over their surroundings, they cannot achieve their wants or perform them, they show some symptoms of behavioral disorders. The purpose of the present study was to provide a causal model of children’s behavioral disorders based on child-mother interaction and parental acceptance with the mediating role of life satisfaction in hyperactive children’s mothers.
Methods: This research was a descriptive correlational study performed by the path analysis method. The statistical population of the present study included all mothers of hyperactive children visiting psychiatric clinics in Tehran in 2020, out of whom 250 mothers were selected using purposive sampling. The research instruments included Children’s Behavioral Disorders Questionnaire (CBDQ), Child-Mother Interaction Questionnaire (CMIQ), Parental Acceptance Questionnaire (PAQ), and Life Satisfaction Questionnaire (LSQ). The proposed model was evaluated using Path Analysis by SPSS Amos 24.0.
Results: The results showed that there is a positive and significant relationship between child-mother interaction/parental acceptance and life satisfaction. Moreover, there was an inverse and significant relationship between child-mother interaction and parental acceptance. The results also showed that the general parental acceptance path had a greater effect on hyperactive children’s behavioral disorders.
Conclusions: The causal model of children’s behavioral disorders based on child-mother interaction and parental acceptance with the mediating role of life satisfaction in hyperactive children’s mothers has a good fit.

Abstract
Introduction: Marital conflicts are among the main factors that threaten marital relations and contribute to conflicts and divorces in Iranian society. The present study has been carried out in order to predict marital conflicts in couples based on a systemic approach mediated by personality traits in the cities of Tehran and Qom.
Methods: The research method was descriptive-correlational. The statistical population consisted of troubled/struggling couples in Tehran and Qom. The sample consisted of 540 men and women with marital conflict selected by convenience sampling. The research instruments included Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness, (NEO) Five-Factor Inventory (NEO-FFI), Marital Conflict Questionnaire (MCQ), and the Family Assessment Device (FAD). Data were analyzed by Pearson correlation method and structural equation modeling using SPSS version 22.0 and LISREL version 8.0 software.
Results: Results revealed that the hypothetical model fit the measurement model (CFI = 0.97; IFI = 0.96; RMSEA = 0.088). In addition, the systemic approach components mediated by personality traits were able to explain marital conflicts (P = 0.001). These components indirectly influenced marital conflicts through personality traits (β = -0.38, P = 0.005).
Conclusions: Overall, the findings verified the marital conflict model based on a systemic approach mediated by the personality traits.
