Abstract
Background: Uterine environment and fetal period can profoundly affect health of the neonat. Hypoxia-inducible factor-1α (HIF-1α) is a transcription factor that regulates cellular stress responses and its activity is essential in both embryogenesis and postnatal life. The aim of the present study was to investigate the effects of maternal swimming on rat pups' HIF-1α levels as a key regulator of oxygen in lungs.
Methods: Sixteen female Wistar rats weighing 180- 200 grams were acclimated to a new environment consisting of equal light-darkness cycle and ad lib access to chow and adapted to the stress caused by water for two weeks. The rats were divided into two swimming and control groups. Swimming training began on the first day of pregnancy in a pool and continued for 3 weeks (1 h/day, 5 days/wk). Pups' lungs were removed two days after birth and their HIF-1α concentration was determined with enzyme-linked immunosorbent assay (ELISA). Statistical analysis of the data was done using independent t-test. A p-value smaller than 0.05 was considered statistically significant.
Results: Swimming lead to a significant (P<0.001) increase in the pups' lung HIF-1α levels compared with the control group. Although 3-wk period of swimming training, showed no significant increase in weight and also lung weight of newborns. Thus it can be concluded that swimming endurance training in pregnancy, can be considered as appropriate alternative in order to embryos development.
Conclusion: Our research suggests that HIF-1α level is an essential element for the development of the lungs of embryos. Moreover, further studies on the lung HIF-1α levels at post-natal period with different modes of exercise will provide more clear insight into the mechanisms of the findings resulting from this study.

Abstract
Background: There are evidences that suggest the impact of stress on pregnancy outcome. Prolong antenatal depression and anxiety may cause lots of adverse pregnancy outcomes such as abortion, still birth, low birth weight and preterm labor. The aim of this pre-posttest randomized control trial study was to determine the role of stress management training in the first trimester on stress reduction in pregnant women referring to General Yas Women Hospital related to Tehran University of Medical Sciences in Tehran, Iran, from May 2014 to January 2016.
Methods: Anxiety status of 75 pregnant women in the first trimester was assessed by standard anxiety questioner using Hamilton anxiety rating score. Scores 18-25, 25-35 and >35 were considered for mild, moderate and severe anxiety, respectively. According to the level of anxiety, women with moderate and severe anxiety as the interventional group were arranged for participation in stress management workshops, applying mindfulness technique including: body scan, setting meditation and passing thought technique in 5 an hour sessions. For this experimental group were made available CD training for practicing lessons during the week. All groups didn’t need to medical treatment according to the psychiatrist interview. In the ending of therapy, clinical groups were assessed by anxiety scale again. Women with mild anxiety as the control group received only regular prenatal care without any psychological interventions. The validity and reliability of questioner were approved by experts in this field. This research was supported by Tehran University of Medical Sciences and Health Services grant and also the study approved by ethics committee of Tehran University of Medical Sciences. Data were analyzed using the statistical software SPSS version 18, and Student’s t-test analyses were performed.
Results: The level of anxiety and stress was decreased significantly between women in clinical groups, 27.5 to 14.1 for moderated level stress (P= 0.001) and 40.1 to 16.6 for high level of stress (P= 0.0001) respectively.
Conclusion: First trimester of pregnancy is a crucial stage of fetal growth and development. Based on our findings, stress management training in this period has beneficial effects on stress reduction and enhances maternal health status.

Abstract
Background: According to the direct connection between congenital hypothyroidism and iodine deficiency in pregnant women, also relatively high incidence of congenital hypothyroidism in some areas of Kerman province, especially Raver district located in North of Kerman province, this study was performed to determine and compare the urinary iodine concentration (UIC) in pregnant women referring to health centers.
Methods: This cross-sectional study was done during March 2014 and May 2015. Inclusion and exclusion criteria to be considered and UIC were measured by spectrophotometry in 384 and 374 pregnant women in Ravar and Kerman cities, Iran. Sampling method for this study was all of pregnant women in Ravar and random stratified sampling in Kerman. data were collected using a structured questionnaire. All statistical analyses were performed using SPSS Software, version 20.0 (IBM SPSS, Armonk, NY, USA). Chi-square test, Pearson's correlation coefficient and Logistic regression were used for associations and differences.
Results: The mean UIC was 200.21 µg/L in pregnant women of Ravar and 238.79 µg/L in pregnant women of Kerman. 22.7% of pregnant women were with low concentrations of iodine, 57.8% within the normal range and 19.5 percent were with high iodine concentrations in Ravar. While 5.3 percent of pregnant women were with low concentrations of iodine, 54.5% were within the normal range and 40.1% were with high UIC in Kerman. There were no significant differences between demographic variables and UIC in the two regions (P> 05/0). Multivariate regression models showed significant connections between the residence and UIC pregnant women (P< 0.001).
Conclusion: The results of this study showed that UIC in pregnant women of Ravar was significantly lower than Kerman and the place of living can be considered as a predictor of UIC in pregnant women.

Abstract
Background: Sexually transmitted infections are the most common human infections that lead to severe complications. Mycoplasma genitalium (MG) and Ureaplasma urealyticum (UU) are common and important cause of genitourinary tract infections. MG is a member of genital mycoplasmas which is emerging as an important causative agent of sexually transmitted infections both in males and females. This study aimed to determine the prevalence of UU and MG in pregnant women and to assess the risk factors which may contribute to the predisposition of the individuals to the infection.
Methods: In this cross-sectional study, The population of 210 pregnant women admitted to the Rasoul Akram Hospital in Tehran, were selected for the study using non-random sampling. The urine specimens were collected from 194 pregnant women from May to December, 2015. The samples were transferred to the Infectious Disease Research Center of Rasoul Akram Hospital under sterile condition. Samples were exposed to DNA extraction followed by multiplex polymerase chain reaction (PCR) to detect the infection. Data including sex, age, history of abortion, history of genitourinary tract infections were collected subsequently.
Results: The prevalence of MG and UU infections in urine samples was 5.6%, 11.2%, respectively. The mean and standard deviation of the risk of UU was 2.08 (3.56-1.22) in women with a history of abortion and 0.70 (1.03-0.47) in women without a history of abortion. There was a significant relationship between the history of sexually transmitted diseases and the frequency of UU (P<0.022). From 22 patients with UU infection, six patients had a history of sexually transmitted diseases. A significant correlation was found between prevalence of MG and UU infections. The History of abortion was significantly related with the frequency of UU and MG infections. The prevalence of MG infection is negatively correlated with pregnancy trimesters. The History of genitourinary tract infections was significantly associated with the frequency of UU.
Conclusion: The presence of UU and MG could be associated with abortion.

Abstract
Pregnancy as a natural event leads to changes in various aspects of physiology, psychology, and social life. The adoption of a health promoting lifestyle is an important strategy for achieving the desired outcomes of pregnancy and is important on the future health of mother and child. The aim of this study was to assess the various aspects of health promotion behaviors during pregnancy. The data was obtained with advanced search in the Iranmedex, Magiran, Scientific Information Database (SID), IranDoc, PubMed, Google Scholar, Web of Science and Scopus databases. Articles containing full text were collected using the proper keywords for Persian articles and their equivalent in Mesh included “Health promotion" OR "Behavior health "OR “Health Promoting Lifestyle” AND pregnancy for English articles with a time limitation of 2010 to 2017. At first 3247 articles obtained after reviewing and evaluation of the references, 4 Persian and 25 English articles with observational and qualitative design were included. A review of studies showed that finding a way to pass pregnancy safely is the most important concern for mothers. Pregnant women do some actions to reach favorable outcomes and they have a high incentive to adopt health behaviors during pregnancy due to fear of fetal health, but there is some obstacle to adopt health behaviors including individual factors like that lack of time and inadequate information about pregnancy or health-related functions and social factors including health system problems and cultural factors. In addition age, level of education, individual’s beliefs and factors associated with pregnancy such as high-risk pregnancy and environmental factors such as social support and health system performance play an important role in the adoption of health behaviors. In order to increase the potential of pregnant women to adopt healthy behaviors, changing the health system approach and paying attention to social determinants of health, in order to carry out the necessary interventions, it is recommended to conduct qualitative studies and appropriate design for deep study of the subject in the cultural background.

Abstract
Background: Today, with the increasing use of ionizing radiation like X-rays in diagnosis and treatment of diseases, the risk of fetal exposure in pregnant women also increases. Therefore, protecting pregnant women from ionizing radiation is essential and is considered as the standard criterion for Medical Radiation Center. So the aim of this study was to investigate the observance of protective principles and 10-day rule in imaging of susceptible women.
Methods: This cross-sectional study was carried out at the Radiography Centers of Semnan University of Medical Sciences, Iran, from July 2017 to September 2017. First, patients who were under radiography, were asked about the knowledge of the radiographers about the 10-day rule and radiation protection. Then a questionnaire with 12 questions was given to the radiographers in radiology and CT scan center. Finally, the existence of protection guidelines for pregnant women was determined by asking manager and checking at the moment.
Results: The patient's question about pregnancy failed about 19%, which did not have a significant relationship with patients' singleness (P=0.0004). Also the mean scores for the knowledge of radiographers about radiation protection were 14.21±0.96, which did not have a significant relationship with their work record and place of employment and their educational level (P=0.09). On the other hand, in half of the radiography centers, the written radiation protection guidelines were not available.
Conclusion: Principles of radiation protection and 10-day rule for radiography of women who were prone to pregnancy were desirable but due to importance of radiation protection, the rules should be more carefully implemented.

Abstract
Background: The health of pregnant mothers is one of the most important health indicators of each country. The midwifery clinic is one of the first places in which pregnant mothers become familiar with at the time they arrive. Providing health services at a desirable level and improving the quality of services in the midwifery clinic require an accurate understanding of the situation and its complications. This study aimed to assess how well pregnant mothers were satisfied with the midwifery services that they have received at midwifery to improve their quality.
Methods: This cross-sectional study was performed on 364 pregnant women who were referred to the midwifery clinic of Shariati Hospital in Tehran in August and September in 2018. Data were collected using a validated, pre-designed questionnaire and were analyzed using chi-square and multivariate logistic regression.
Results: Among the pregnant women referred to the clinic, 70.2% were satisfied with the care services received and 29.8% of them were not satisfied. This satisfaction level had a significant relationship with pregnancy (P=0.009) and mothers' age (P<0.001) while decreased by the increment in the number of pregnancies and age. Also, in this study, the least satisfaction was related to the crowds and waste of time and lack of access to the parking spot (P<0.001). In this research, the least satisfaction was due to crowding and waste of time, which can be addressed by improvement in the health services in the residential areas, appropriate referrals, informing about the expected time of arrival, and providing information on the alternative of the new hospitals in areas around the city with less traffic congestion and better parking sites.
| Conclusion: The results of our study showed the detailed patient satisfaction factors of an educational medical hospital. In overall the satisfaction. |

Abstract
Background: Despite years of continuous research, maternal mortality due to preeclampsia is still a serious threat. Researchers believe that preeclampsia is a multifactorial disease and proposed many risk factors including immunological factors for it. Given the description of preeclampsia as an excessive response of the immune system, the relationship between preeclampsia and immunological changes is of particular importance. Genetic polymorphisms are considered to be one of the causes of immunological defects. Due to the role of immunologic and inflammatory factors in the etiology of preeclampsia, in the present study, the association of rs1028181-513T/C polymorphism of interleukin 19 gene with preeclampsia in the patient and control groups who were referred to Valiasr hospital in Kazerun, was compared.
Methods: The present case-control study was conducted at Islamic Azad University of Kazerun from December 2016 to May 2017. 150 preeclampsia patients and 150 healthy pregnant women who were referred to Valiasr hospital in Kazerun, were enrolled. Genotypes of participants for the -513T/C (rs1028181) variant were determined by the Tetra Primer ARMS-PCR method. SPSS software and Chi-square statistical test were used for data analysis.
|
Results: In the position of the -513T/C (rs1028181) polymorphism, a significant difference in frequency of all genotypes (CC, CT and TT) (P=0.001) and both alleles (C and T) (P=0.002) between preeclampsia pregnant women and healthy pregnant women was observed. There was no significant relationship between the other parameters of the study with the mentioned polymorphism in the patient and control groups.
Conclusion: Due to the significant relationship between (rs1028181) -513T/C polymorphism and the occurrence of preeclampsia, which emphasizes the role of genetic predisposition in the development of preeclampsia disease, the presence of this polymorphism can be considered as a predictor of preeclampsia and concluded that polymorphic genetic markers are good predictive strategies for early detection of preeclampsia before the twentieth week of pregnancy.

Abstract
Background: Streptococcus beta group (GBS: Group B Streptococcus) is a gram-positive coccus that colonizes in the rectovaginal area. About 4.6% to 31.3% of women of childbearing age carry GBS infection. GBS colonization is a risk factor for subsequent infections in pregnant women that can be transmitted to the fetus through vertical transfer and aspiration of infected amniotic fluid. 2% of cases lead to an invasive infection in the baby. In most countries, treatment is done according to the CDC (Centers for Disease Control and Prevention) protocol which is based on culture results. According to studies conducted in our country, treatment is based on risk factors. Therefore, during this study, we decided to compare the results of treatment based on risk factors and treatment based on culture results and other maternal and neonatal complications in these two groups.
Methods: This case-control study was performed on 98 pregnant women aged 35 to 37 weeks who were referred to the perinatal clinic of Arash Hospital from April 2018 to the end of March 2020 and also 200 pregnant women with a GBS risk factor. Samples of rectovaginal discharge of 98 pregnant women were sent to a selected laboratory for culturing. In this group, treatment was performed based on the culture result. The control samples included 200 pregnant mothers who were treated based on risk factors without culture. Then the two groups were compared in terms of pregnancy outcomes.
|
Results: Out of 98 subjects, 24 (24.5%) had positive rectovaginal culture. Individuals treated with antibiotics based on positive culture results did not show a significant difference in terms of observed pregnancy outcomes compared with the control group.
Conclusion: The prevalence of GBS colonization was significantly higher in patients with a history of vaginal discharge than in those without a history. Due to the small number of studies conducted in Iran, it is recommended to conduct studies with a larger sample size in order to explain a more appropriate protocol in terms of effectiveness and economics.

Abstract
Background: Preterm premature rupture of membranes (PPROM) is one of the factors that can increase maternal and neonatal mortality, which is affected by several factors. This study aimed to investigate the factors affecting the frequency of preterm premature rupture of membranes in pregnant women.
Methods: This descriptive-analytical study was conducted in Afzalipour Hospital in Kerman from January 2018 to January 2019. All pregnant women with PPROM and normal pregnant women referred to this Hospital were included in the study through convenient sampling. The data collection tool was a checklist containing patients' demographic information (age, education, occupation, gestational age, number of pregnancies, urinary tract infection (confirmed by the attending physician), history of premature rupture of the water sac, vaginal bleeding (bleeding in any period of pregnancy as the person had visited the doctor), history of premature birth, pregnancy care and trauma (any trauma)). To analyze the data, descriptive statistics (frequency, percentage, mean, and standard deviation), analytical (Chi-square test) and SPSS software version 22 were used.
|
Results: In this descriptive-analytical study, 400 pregnant women were studied. Two hundred of pregnant women had preterm premature rupture of membranes and 200 of pregnant women did not have such condistion and were normal. The mean age of pregnant women was 27.4±5.4 years old and the mean gestational age of pregnant women was 34.1±2.1 weeks. The mean parity of pregnant women was 2.3±1.4. Risk factors such as maternal age (P=0.011), number of pregnancies (P=0.035), maternal education (P=0.018), history of preterm premature rupture of membranes (P=0.046), history of preterm delivery (P=0.019), trauma (P=0.037) and pregnancy care (P=0.037) affected preterm premature rupture of membranes.
Conclusion: The results of this study showed that maternal age, number of pregnancies, maternal education, and history of preterm premature rupture of membranes, history of preterm delivery, trauma, and prenatal care are risk factors for PROM. Therefore, by educating pregnant mothers about these risk factors, the incidence and complications of preterm premature rupture of membranes can be reduced.
