Air pollution is the world's largest environmental health threat to humans and has wide-ranging adverse effects on the environment. The term ventilation coefficient (VC), which is a function of the average wind speed through the planetary boundary layer (PBL) and the PBL height (PBLH), can be used to estimate air pollution potential. We analyzed PBLH, wind speed through PBL, and VC over Tehran using ERA5, and PM2.5 surface concentration using MERRA-2 during 1991-2020. Both PBLH and VC undergo substantial diurnal variations, with higher values during the day and much lower values at night. As a result, PM2.5 concentration in Tehran is the maximum in the early morning, while it is relatively lower in the afternoon. The average wind speed through PBL shows the same diurnal variation in all seasons, except in winter when winds in PBL are stronger at night than during the day. Both PBLH and VC over Tehran show substantial seasonal variations, with much higher values in summer followed in decreasing order by spring, autumn, and winter, highlighting an extremely high air pollution potential in winter. Hence, due to high pollutant emissions, the occurrence of severe air pollution is expected to be a common feature in Tehran in winter. PBLH has significantly increased over Tehran both during the day and at night for the period 1991-2020, primarily in response to the surface warming in recent decades, while wind speed through PBL has significantly declined only at night. The overall impact of such changes is an increase in VC over Tehran both during the day and at night, although the increasing trend of VC is statistically significant only at night. Our results highlight the urgent need for the implementation of effective sustainable policies to reduce air pollution and its adverse effects in winter when air pollution potential is high in Tehran., (© 2023.

Background and Aims: Preterm birth (PTB) is the leading cause of perinatal mortality and morbidity, progesterone is one of the main hormones to maintain a normal pregnancy. However, there are still conflicting results regarding using progesterone supplementation to prevent PTB and improve neonatal outcomes. The length of treatment with progesterone supplementation is also one of the challenges ahead, so the present study was conducted to investigate the relationship between the duration of progesterone supplementation treatment and neonatal outcomes., Methods: This retrospective cohort study was conducted on pregnant women at risk of PTB and who have taken progesterone supplementation. They were asked about the length of treatment with progesterone supplements and finally, the neonatal outcomes of these women were measured., Results: A total of 265 pregnant women who met the inclusion criteria were included in this study and the subjects were divided into two groups that received progesterone <12 weeks and received progesterone ≥12. In the group of women receiving progesterone with a treatment duration of ≥12 weeks, the rate of preterm labor, respiratory distress syndrome, low birth weight, and the need for hospitalization were significantly lower than in the group receiving progesterone with a treatment duration of ≥12 weeks., Conclusion: Progesterone administration for longer than 12 weeks in women at risk of PTB can improve neonatal outcomes., Competing Interests: The authors declare no conflict of interest., (© 2023 The Authors.

Background and Aim: Although various surveys have been conducted for sexual problems, there is a lack of population-based studies on sexual distress in Iran. Thus, we sought to determine the prevalence and predictive factors of sexual distress in this population., Methods: Overall, 1000 married women aged 16-49 years were enrolled in this study using the two-stage cluster sampling method. To identify sexual distress, the female sexual distress scale-revised (FSDS-R) was completed. The predictive factors were assessed using a checklist., Results: A total of 318 women (31.8%) suffered from sexual distress. Among socio-demographic factors, satisfaction with marriage ( p  = 0.001), among personal factors history of infertility and fear of contracting sexually transmitted infections ( p  < 0.01), and among sexual and interpersonal factors satisfaction with the level of sexual desire ( p  = 0.01), pain during sexual intercourse ( p  < 0.01), premature ejaculation disorders in the partner ( p  < 0.05), and sexual satisfaction ( p  < 0.001) were significantly associated with sexual distress., Conclusion: Clinicians should evaluate sexual distress comprehensively and consider all the related dimensions. The high overall prevalence of sexual distress, with or without an identifiable dysfunction, signals the importance of health professionals being adequately prepared to discuss sexual health concerns., Competing Interests: The authors declare no conflict of interest., (© 2023 The Authors.

Background: To effectively manage sexual health, people must have access to sexual health services. A small percentage of women with sexual concerns seek professional help. Hence, the need to explain the help-seeking challenges is felt from the perspective of women and health care providers., Methods: This study explored Iranian women's challenges when seeking help for sexual concerns. Using a purposive sampling method, 26 in-depth interviews were conducted in Rasht in 2019-2020. The participants included sexually active women of reproductive age over 18 years old and 8 health care providers. The recorded interviews were transcribed and analyzed through content analysis., Results: From the description of 17 subthemes provided by the participants, two main themes were achieved, "Unfavorable sexuality development context" and "Inefficient sexual health services.", Conclusions: According to the results, it is suggested that policymakers pay more attention to the challenges women and health care providers face in help-seeking and promote sexuality education and sexual health services to achieve a higher level of help-seeking among women., (© 2023.

Background: One way of dealing with pregnancy-related anxiety is through women's beliefs. This study aimed to assess the effect of spiritual self-care blended learning on anxiety in women with preterm labor., Methods: A non-blinded and parallel randomized clinical trial was conducted in Kashan, Iran, from April to November 2018. In this study, 70 pregnant women with preterm labor were randomized to intervention and control groups (35 each) by flipping a coin. For the intervention group, spiritual self-care training was delivered through two face-to-face sessions and three offline sessions. The control group received routine mental healthcare. The data were collected using socio-demographic information and the Persian Short Form of the Pregnancy-Related Anxiety (PRA) Questionnaires. Participants filled out the questionnaires at baseline, immediately after the intervention, and four weeks after it. Chi-square, Fisher's exact test, independent t-tests, and repeated measures ANOVA were used to analyze the data. SPSS v.22 was used, with a significance level of P<0.05., Results: At baseline, the mean PRA scores in the intervention and control groups were 52.25±29.23 and 49.68±21.66, respectively (P=0.67). There were significant differences immediately after the intervention (28.02±12.13 and 51.42±20.99 in the intervention and control groups, respectively) (P<0.001), and four weeks post-intervention (25.45±10.44 and 52.17±21.13 in the intervention and control groups, respectively) (P<0.001); PRA was lower in the intervention group., Conclusion: Our results revealed the positive effect of spiritual self-care intervention on anxiety in women with preterm labor, so this intervention could be integrated into prenatal care.

Background: Medicalization may lead to over-testing during pregnancy and increased cesarean section (CS). This study investigated the medicalization of low-risk pregnancies and childbirths in Rasht, Iran., Methods: In this cross-sectional study, 337 postpartum women completed a demographic questionnaire and the Medicalized Pregnancy and Childbirth checklist. In this study, medicalization indicators were the source of providing prenatal care, prenatal screening for aneuploidy, number of received care, hospitalization before the onset of labor, intrapartum drug use, and CS. Demographic data were reported using descriptive statistics. Chi-square or Fisher's exact and Man-Whitney tests were used for comparison purposes. Logistic regression was run to determine the medicalization indicators associated with the mode of childbirth., Results: Of the participants, 82.2% received prenatal care from obstetricians, 85.8% had undergone prenatal screening tests. There was a significant difference between the median number of ultrasound examinations (P=0.006), prenatal screening for aneuploidy (P=0.002), and multivitamin/mineral supplements use (P<0.001), according to the source of providing prenatal care. Of the participants, 67.1% had CS. Women who received prenatal care from obstetricians had about 2.3 times more odds of CS (OR=2.23, P=0.019). Furthermore, with the increased number of ultrasounds, the odds of CS augmented by 25% (OR=1.25, P=0.013). Finally, 26.4% of the participants were hospitalized before the onset of labor; the intervention increased the odds of CS more than twice (OR=2.08, P=0.026)., Conclusion: The study showed a picture of medicalization in low-risk pregnancies. Of the medicalization indicators, the source of providing prenatal care, time of admission, and use of ultrasounds were associated with CS. Midwife-led care could diminish medicalization., (Copyright: © International Journal of Community Based Nursing and Midwifery.)

Background: Sexual desire and sexual distress are determined by emotional, psychosocial, hormonal, and anatomical factors during pregnancy., Objective: To identify the factors contributing to female low sexual desire and sexual distress during pregnancy separately and concurrently., Materials and Methods: Overall, 295 pregnant women were enrolled in this cross-sectional study. Sexual desire and distress were assessed by the sexual interest and desire inventory-female (score ≤ 33.0 indicates low sexual desire) and the female sexual distress scale-revised (score ≥ 11 indicates sexual distress)., Results: 56.3% and 17.3% of pregnant women met the clinical cut-off for low sexual desire and sexual distress, respectively. After adjusting for the effect of the confounding variables by logistic regression multivariate analysis, satisfaction with body image before and during pregnancy, frequency of sexual intercourse, and satisfaction with foreplay were found to be significantly associated with low sexual desire. Factors related to sexual distress were similar to those noted for common sexual desire, except for satisfaction with foreplay. Other factors related to sexual distress included increased age, fear of abortion, and pregnancy trimester. Factors linked to concurrent low sexual desire and sexual distress were similar to those found for sexual distress, except for pregnancy trimester., Conclusion: Low sexual desire and sexual distress are relatively common sexual experiences during pregnancy. Several factors could predict low sexual desire but were not associated with sexual distress, and conversely. Comprehensive attention to all of these factors is essential while screening for sexual health during pregnancy., Competing Interests: The authors declare that there is no conflict of interest., (Copyright © 2021 Malary et al.)

We propose an image-based class retrieval system for ancient Roman Republican coins that can be instrumental in various archaeological applications such as museums, Numismatics study, and even online auctions websites. For such applications, the aim is not only classification of a given coin, but also the retrieval of its information from standard reference book. Such classification and information retrieval is performed by our proposed system via a user friendly graphical user interface (GUI). The query coin image gets matched with exemplar images of each coin class stored in the database. The retrieved coin classes are then displayed in the GUI along with their descriptions from a reference book. However, it is highly impractical to match a query image with each of the class exemplar images as there are 10 exemplar images for each of the 60 coin classes. Similarly, displaying all the retrieved coin classes and their respective information in the GUI will cause user inconvenience. Consequently, to avoid such brute-force matching, we incrementally vary the number of matches per class to find the least matches attaining the maximum classification accuracy. In a similar manner, we also extend the search space for coin class to find the minimal number of retrieved classes that achieve maximum classification accuracy. On the current dataset, our system successfully attains a classification accuracy of 99% for five matches per class such that the top ten retrieved classes are considered. As a result, the computational complexity is reduced by matching the query image with only half of the exemplar images per class. In addition, displaying the top 10 retrieved classes is far more convenient than displaying all 60 classes.

Background: Infertility is a significant psychological stressor among infertile couples. Aggressive behaviour such as domestic violence may be the consequence of this situation., Aims: To determine the relationship between domestic violence and infertility and its associated factors., Methods: This unmatched case-control study was conducted on 400 women who were referred to Al-Zahra teaching Hospital in Rasht, Islamic Republic of Iran, from May to December 2015. The data were collected by WHO Domestic violence questionnaire, which was validated in the Islamic Republic of Iran. Data were analyzed by using descriptive and analytical statistic (Chi square, t test, and logistic regression)., Results: Out of the 200 infertile women 136 (68%) reported a history of physical violence, 120 (60%) had experienced sexual violence and 140 (70%) had psychological violence. There was a significant relationship between infertility and physical, sexual and psychological violence (P < 0.05). Logistic regression analysis revealed that the education level of women [OR= 0.176, 95% CI (0.070-0.446)], unemployment husband [OR=15.83, 95% CI (1.307-191.977)] and infertility [OR= 0.133, 95% CI (0.057-0.31)] were associated with domestic violence (P < 0.05)., Conclusions: In this study there was a relationship between infertility and physical, sexual and psychological violence and infertile women were more likely to encounter domestic violence. Screening for domestic violence is necessary for infertile couples., (Copyright © World Health Organization (WHO) 2019. Some rights reserved.

Background/aim: The prognostic value of the red cell distribution width (RDW) as a cost-effective and noninvasive test in acute pulmonary embolism (PE) is still unknown. We aimed to investigate the prognostic value of the admission RDW level in the long-term survival of PE patients. Materials and methods: In this registry-based, prospective cohort study, a total of 378 patients (mean age: 60.4 ± 17.11 years, 47.4% female) who presented with acute PE were enrolled. All the clinical data for each patient were obtained from our institutional PE registry. The follow-up was performed at a median time of 17 months. The primary endpoint was death at follow-up. Results: The mean RDW in study patients was 14.67 ± 2.13. The all-cause mortality rate during the follow-up was 15.6% (n = 59). After adjustment for potential confounders, the relationship between RDW and long-term mortality showed a trend of a significant level (hazard ratio: 1.109; 95% CI, 0.998−1.232; P = 0.053). We divided patients into 3 groups based on the European Society of Cardiology’s classification. As we moved from the low risk to the higher risk categories, the mean RDW increased significantly (P = 0.037). Conclusion: It seems there may be an independent association between RDW at presentation and PE mortality within 17 months.
