The effect of health belief-based education on physical activates of nulliparous women: A randomized control trial

Background: Regular physical activity during pregnancy is known to have positive effects on the health of the mother and fetus. However, reports indicate that more than half of pregnant women in Iran do not have adequate physical activity. This study was conducted in order to change the behavior of pregnant women in regard to physical activity and also to develop suitable educa-tional/interventional measures. Objectives: This study was conducted to investigate the effects of health belief-based education on the physical activity of nulli-parous women. Methods: This triple blinded randomized control trial was conducted among 64 nulliparous women attending the health centers of Ilam, Iran, in 2018. Participants were selected randomly by the cluster sampling method and were allocated to the two groups of control and intervention. Participants in the intervention groups received education and theoretical training based on the health belief model for at least 45 minutes, and then individual practical training was provided. Samples in the control group received routine pregnancy training. Data were collected in two pre-test and post-test stages by a valid questionnaire and were analyzed by SPSS, version 19, using statistical tests, including Chi-square, paired t-test, and independent t-test. Results: The results showed that the levels of perceived sensitivity (-4.750 ± 2.119), (t = 12.215, P ≤ 0.001), perceived severity of threat (-5.312 ± 1.874), (t =-16.036, P < 0.001), perceived benefits (-2.750 ± 1.502), (P < 0.001, t =-10.352), and self-efficacy (-3.656 ± 1.405), (P < 0.001, t =-14.708) in the intervention group significantly increased after the training compared to pre-training. Also, the level of perceived barriers (4.093 ± 1.444), (P < 0.001, t = 16.027) after the training was significantly less than pre-training level. In the intervention group, the total physical activity with the intensity of moderate/severe (2049/000 ± 963.342), (P < 0.001, t =-12.032) was significantly higher than pre-training. Conclusions: The results of this study indicated that training based on the health belief model can increase the physical activity of pregnant women with moderate/severe intensity and bring it to the optimal level of 150 minutes per week by increasing the health beliefs of pregnant women. Therefore, it is suggested that training based on this model should be appropriately incorporated into the routine education of pregnant women. © 2020, Author(s)

The relationship between phoH and colistin-heteroresistant in clinical isolates of Acinetobacter baumannii

Heteroresistant phenotype is defined as a subpopulation of major bacteria with a minimum inhibitory concentration (MIC) higher than the original population. The molecular mechanisms of this phenotype have not yet been fully described. Therefore, finding its molecular mechanisms to control infection and prevent disease recurrence in the world is of great importance. This study investigated the relationship between phoH and heterogeneity to colistin in A. baumannii clinical isolates. A total of sixty A. baumannii isolates were isolated from the burn ward of Tehran hospitals and identified by biochemical test, and confirmed by molecular methods. The MIC values of the isolates relative to colistin were determined using the broth micro dilution method, and then heteroresistant isolates were identified using the modified population analysis profile (PAP) method. Finally, phoH gene expression in heteroresistant isolates and non-heteroresistant isolates was compared by RT-qPCR. All isolates were intermediate to colistin (MIC <2), and out of 60 confirmed isolates, seven isolates were heteroresistant (11.66). Quantitative real-time PCR results showed that phoH expression was high in the heteroresistant group, while phoH expression was the lowest in Non-heteroresistant. This study indicates that the phoH gene can be considered an anti-heteroresistant target against colistin in A. baumannii isolates, although further studies are needed

Optimism, Communication Skills and Its Related Factors in Midwifery Students

Introduction: Optimism is a tendency towards life and its events. It can affect health via the promotion of social relationships. Aim: This study aimed at investigating optimism, communication skills, and its related factors in midwifery students. Materials and Methods: This descriptive-analytic study was conducted during September to December, 2016. Participants were 115 midwifery students from Ilam University of Medical Sciences who were enrolled into this study through census sampling. Data were collected using demographic characteristics, communication skills, and life-orientation questionnaires. Data were analysed using descriptive and analytical statistics in SPSS version 16. Results: The mean score of communication skills and optimism was 108.9 +/- 10.9 and 13.9 +/- 3.5, respectively. Pearson's correlation coefficient showed that there was a direct correlation between communication skill and optimism scores (r=0.477, p<0.001). Analytical statistical analysis showed a direct relation between age and communication scores (p=0.01) and there was a significant relation in the mean score of communication skills in married people than in single ones (p=0.02). Also, there was a significant correlation between optimism score and the level of awareness of the field of study (p<0.001). Conclusion: In this study, the level of communication skills in midwifery students in Ilam University of Medical Sciences, Iran was moderate and comprehensive training is needed to improve these skills. The level of optimism of life in most midwifery students was relatively good, but more studies are suggested in this regard

The prevalence of gonococcal and non-gonococcal infections in women referred to obstetrics and gynecology clinics

Bacterial vaginosis is a condition caused by changes in the vaginal microbial ecosystem and increases the risk of preterm delivery, premature rupture of membranes, endometritis, and weight loss of the baby. This study aimed to evaluate the frequency of gonococcal and non-gonococcal genital infections in women referred to clinics in Ilam, Iran. Two swab samples were taken from each patient using a sterile swab, one swab was placed in a THB medium for the culture of Streptococcus agalactiae and the other in PBS buffer for PCR. PCR method was conducted for the identification of the other bacterial agents such as Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma urealyticum, and also S. agalactiae. Sampling was performed on 169 women with symptomatic vaginosis. The frequency of S. agalactiae by culture and PCR methods was 4.7 (8 samples) and 13.6 (23 samples) respectively. Also, 6.5 (11 samples), 3.5 (6 samples), 4.1 (7 samples), 1.2 (2 samples), and 0 of the samples were positive for N. gonorrhoeae, M. genitalium, M. hominis, U. urealyticum and C. trachomatis by PCR method. Except for a significant association between S. agalactiae colonization and abortion, there was no significant correlation between the prevalence of these bacteria and the patient's age, age of marriage, number of deliveries, and number of abortions. Overall, the prevalence of gonococcal and non-gonococcal infection in women referred to clinics in Ilam is similar to the other parts of Iran

A Review on Recent Development of Cooling Technologies for Photovoltaic Modules

When converting solar energy to electricity, a big proportion of energy is not converted for electricity but for heating PV cells, resulting in increased cell temperature and reduced electrical efficiency. Many cooling technologies have been developed and used for PV modules to lower cell temperature and boost electric energy yield. However, little crucial review work was proposed to comment cooling technologies for PV modules. Therefore, this paper has provided a thorough review of the up-to-date development of existing cooling technologies for PV modules, and given appropriate comments, comparisons and discussions. According to the ways or principles of cooling, existing cooling technologies have been classified as fluid medium cooling (air cooling, water cooling and nanofluids cooling), optimizing structural configuration cooling and phase change materials cooling. Potential influential factors and sub-methods were collected from the review work, and their contributions and impact have been discussed to guide future studies. Although most cooling technologies reviewed in this paper are matured, there are still problems need to be solved, such as the choice of cooling fluid and its usability for specific regions, the fouling accumulation and cleaning of enhanced heat exchangers with complex structures, the balance between cooling cost and net efficiency of PV modules, the cooling of circulating water in tropical areas and the freezing of circulating water in cold areas. To be advocated, due to efficient heat transfer and spectral filter characters, nanofluids can promote the effective matching of solar energy at both spectral and spatial scales to achieve orderly energy utilization
