Behzad Nazemroaya, Fatemeh Kazemi Goraji , Azim Honarmand, Mohammad Saleh Jafarpisheh ,
Volume 80, Issue 11 (February 2023)
Abstract
Background: Double lumen tube (DLT) is used in lung surgeries. Classically, the patient should undergo fiberoptic bronchoscopy (FOB) to confirm the location of the DLT and its proper function. However, the sensitivity of ultrasound and clinical methods in diagnosing the correct position of DLT has not yet been definitively determined. This study was designed to assess the accuracy of point-of-care ultrasound and auscultation versus Fiberoptic Bronchoscope in determining the position of the Double-Lumen Tube.
Methods: This cross-sectional study of diagnostic value measurement type was conducted on patients who were candidates for double lumen implantation. After induction of anesthesia, DLT with the appropriate size was implanted, and then the position of DLT was evaluated. In the first step, the lungs were examined by auscultation, then the ultrasound was performed, and two signs of lung pulse sign and lung sliding sign were examined as signs of normal lung and ventilated lung. FOB was performed by an anesthesiologist. At the end, by opening the chest after surgery, the surgeon's opinion about the quality of lung collapse was recorded.
Results: In our study, the correct placement of the tube was correct in 37 cases and wrong in 3 cases, which were checked and corrected by FOB. Vital signs of the patients were stable before and during the operation. There were no problems with anesthesia during the surgery. Diagnostic sensitivity of lung auscultation clinical examination was 64.9% and chest ultrasound was 91.9%. The sensitivity of ultrasound compared to auscultation was not significant (P=0.242), but there was a clinically significant difference in the positive predictive value of the two, so that the positive predictive value of lung auscultation was 88.9% and lung ultrasound was 91.9%. In terms of surgeon satisfaction level, 22 cases (59.5%) had excellent satisfaction and 15 cases (40.5%) had moderate satisfaction. The sensitivity of ultrasound was not significant in comparison with the surgeon's satisfaction.
Conclusion: Ultrasound can be a good substitute for FOB. Although ultrasound cannot have all the functions of FOB, but having advantages such as lower cost, speed of operation, and non-invasiveness, makes it more practical than FOB.

Abstract
Background: Stem cells play an important role in tissue regeneration and treatment of diseases. This study aimed to investigate the awareness, knowledge and attitudes regarding stem cell donation among different people in the community.
Methods: In this systematic review study, Persian keywords and English keywords such as awareness, knowledge, stem cells, embryonic stem cells, adult stem cells, cord blood stem cells and donation were selected according to MeSH database and then these selected keywords have been searched in the academic databases such as PubMed, Scopus, OVID, Science Direct, Iran Medex and SID. In addition, these selected keywords have been searched in the search engines such as Google Scholar, between January 2010 to December 2021.
Results: The results of this study found a total of twenty-five articles related to the awareness, knowledge and attitudes regarding stem cell donation among different people in the community. They were selected. In this study there were 10 cross-sectional studies, 2 descriptive-cross-sectional studies, 5 descriptive studies, 1 mixed method study, 1 semi-experimental study, 1 intervention study, 1 survey study, 1 review study, and the study type was not mentioned in three studies. Most of the studies were conducted in countries such as India, Saudi Arabia, and then United States (USA) and Turkey. Only one article was found in Iran. The results of studies have shown that the level of awareness and attitude of the majority of different people in the community towards the donation and use of stem cells is medium and low. However, most people have a good and positive attitude towards the donation and use of stem cells and mention the use of stem cells as an effective way to treat diseases.
Conclusion: Considering the importance and application of stem cells, it is suggested that managers and planners provide the necessary conditions to implement educational programs to raise the level of awareness and attitude of different people in the community towards stem cell donation.

Abstract
Background: Patient satisfaction is considered as one of the most important elements of the evaluation of healthcare centers. In this research, the level of satisfaction of infertile patients was evaluated.
Methods: This study is a cross-sectional descriptive study. The research population is infertile patients who referred to the infertility clinic (at least 4 visits) and hospitalized in four hospitals affiliated with the Tehran University of Medical Sciences. The satisfaction questionnaire was valid researcher-made which included 56 questions in 9 areas, and were collected from May 2021 to September 2022. In order to comply with the ethical principles in research, hospitals were named 1-4.The results were analyzed using the chi-square test or Fisher's exact test for qualitative variables and analysis of variance for quantitative variables in SPSS software, version 24 (SPSS Inc., Chicago, IL, US).
Results Three hundred–four infertile women in four hospitals were studied. The mean age of the participants was 33.8 years, with a standard deviation of 5.8 years. The average satisfaction with admission and discharge services, medical services, nutrition, accounting, and insurance services in the number-1 Hospital had the highest score, and the average satisfaction with nursing or midwifery services, diagnostic and therapeutic services (radiology/laboratory), hospital services, charter patient rights, management services, paid expenses in Hospital 4 received the most points. The mean score of satisfaction was the highest among those who visited the infertility clinic of Hospital 3 (161.54±21.41). Average satisfaction with admission and discharge services, medical services, nutrition, accounting, and insurance services in Hospital No. 1 had the highest score, and average satisfaction with nursing or midwifery services, medical diagnostic services (radiology/laboratory), hospital services, respecting the patient's rights, management services, paid expenses in hospital number 4 got the most points. The average of nursing or midwifery services, respecting the patient's rights, and hotelling in all hospitals received the highest score, respectively, and nutrition services and paid expenses received the lowest points (most dissatisfaction) (P<0.05).
Conclusion: The level of satisfaction of women referring to the infertility clinic in 35.9% of cases was considered to be at an appropriate and exceptional level, in 49.3% of cases it was at a partially appropriate level, and in 14.8% at an inappropriate level.

Volume 81, Issue 1 (April 2023)
Abstract
Background: The rate of exclusive breastfeeding in Iran at the ages of 3 and 6 months is estimated to be 44% and 27%, respectively, which is still far from the optimal index of the World Health Organization until 2030 (70% in the first six months). In order to monitor breastfeeding counseling centers, which have been set up with the aim of promoting breastfeeding and supporting mothers who have problems with breastfeeding.
Methods: This is a descriptive-retrospective study and all the mothers who were referred to the Health and Treatment Center No. 2 in Mashhad between April 2019 and March 2019 were examined. This health center has two active counseling clinics and the collection of information is based on documents registered in offices and computers. The inclusion criteria for study were not having breast diseases, having an infant child, being able to read and write and living in Mashhad city. The exclusion criteria were also the unwillingness to participate in the study and the newborn suffering from diseases that are incompatible with breastfeeding. Therefore, census sampling was done. The data were analyzed using SPSS 16 software and the significance level was less than 0.05.
Results: In 42.8% of cases, mothers had started feeding combined formula with breast milk before visiting, and in 28.1% of cases, when referring to counseling milk clinics, it was reported that the baby was fed only with formula. After breastfeeding consultations and follow-ups at the end of six months, the rate of exclusive breastfeeding is 34.1% (12% increase compared to the initial reference) and combined formula feeding with breastmilk is 27.8% (a 22% decrease compared to the first visit). And feeding with powdered milk alone was calculated to be 36.5% (an increase of 8.4% compared to the first visit).
Conclusion: The positive role of breastfeeding counseling center in reducing the cases of artificial feeding is clear, and it is recommended to prepare written instructions based on the challenges in breastfeeding for breastfeeding counseling in the first month after delivery.

Volume 81, Issue 3 (June 2023)
Abstract
Background: Insomnia is the most common sleep disorder that is associated with cortical hyperexcitability. Potentially transcranial direct current stimulation (tDCS) modifies the cortical state related to insomnia. Therefore, we hypothesized that by using tDCS the intensity of insomnia can be reduced, followed by improvement of the mood symptoms.
Methods: This study was an experimental design with a pre-test and post-test with a control group. The statistical sample included 32 females with chronic insomnia that were randomly divided into an experimental group (active stimulation) and a control group (sham stimulation). Transcranial direct current with an intensity of 2 mA was applied for 30 minutes during 12 sessions (three times in the week) in the active stimulation group. In this protocol, anodal stimulation of left Superior temporal gyrus (STG) and cathodal stimulation of right dorsolateral prefrontal cortex (DLPFC) and left secondary motor cortex (SMA). In the control group, sham stimulation was performed for 30 minutes during 12 sessions (three times in the week). The participants were evaluated before and after of the intervention using the Insomnia Severity Index (ISI) and Positive and Negative Affect Scale (PANAS).
Results: The findings of this research showed that the application of transcranial direct current stimulation was effective in reducing the severity of insomnia and improving positive and negative affect (P<0.001, F=19.87). The value of this effect (eta2) in the severity of insomnia, negative mood and positive mood is 0.64, 0.34 and 0.6 respectively.
Conclusion: The results of the present study showed that the implementation of our designed tDCS protocol for the treatment of insomnia, significantly reduced the intensity of insomnia in women with chronic insomnia and improved their mood symptoms.

Volume 81, Issue 5 (August 2023)
Abstract
Background: The aim of the present study is to determine the accuracy of ultrasound imaging in the diagnosis of metastatic lymph nodes compared to postoperative pathology samples of patients with papillary thyroid cancer.
Methods: This study was carried out using a descriptive and analytical epidemiological method on 103 known patients with papillary thyroid cancer who referred to Imam and Golestan hospitals in Ahvaz for neck ultrasound from September 2021 to August 2022. A total of 103 patients (including 94 women (91.3%) and 9 men (8.7%)) with papillary thyroid cancer with an average age of (39.8±11.9) were included in the study. The average tumor size in these patients was estimated to be (16.8±10mm). The ultrasound results of these patients before surgery were compared with the pathology results of these patients after surgery.
Results: According to the obtained results, metastatic involvement of cervical lymph nodes was diagnosed in 36.6% of patients (38 people). Of these, 30.7% of patients (32 people) were real positive. The results of ultrasound before surgery were shown as false positive in 9.5% of patients (6 people). Lymphatic metastasis was not seen in 58.4% of patients (60 people) before surgery, which was consistent with the pathology result after surgery (true negative). The positive predictive value of examining metastatic lymph nodes by ultrasound was estimated at 84.2% and the negative predictive value at 92.3%. The diagnostic accuracy of ultrasound was 89%, the sensitivity rate was 86%, and the specificity rate was 90% with the area under the curve AUC=0.884 and P<0.001. Ultrasound accuracy is not affected by tumor size, Hashimoto's thyroiditis and metastasis location (P<0.05). In patients with Hashimoto's thyroiditis, the tumor size increases significantly more than 10 mm.
Conclusion: Ultrasound alone has an acceptable diagnostic accuracy in detecting metastatic lymph nodes caused by papillary thyroid cancer. However, the incidence of false negative error increases as the tumor size decreases.

Abstract
Background: With a national vaccination program, we have achieved success in the prevention of infectious diseases in the community especially in children. Despite this great success, the side effects of vaccination may not encourage some people in the community to get vaccinated. In this study, we investigate the prevalence of common side effects of vaccination in Shahrood city.
Methods: This study investigated the incidence of complications caused by vaccination in infants and children under seven years old in Shahrood city in a 5-year period from April 2016 to March 2020. We collected demographic and clinical information, by referring to the health centers and complications recorded after routine vaccinations such as fever, rash, diarrhea, swelling and other complications of vaccination were collected.
Results: Findings Among the 429 registered complications between 2016 and 2020, most complications were related to pentavalent and trivalent vaccines. Among the registered complications, high fever is the most common complication in both term and pre-term groups. (202 cases, 47.1%) other complications included maculopapular rash (59 cases), mild local complications (55 cases), vomiting (41 cases), and continuous screaming (36 cases), respectively. Among these, 123 cases were resolved without treatment, 297 cases were resolved with drug treatment on an outpatient basis, and only  eight cases required hospitalization.
Conclusion: In general, the vaccination program is highly effective despite having limited side effects.  Knowing this information, can increase vaccination in the country.

Kasra Mardani, Farhad Nikkhahi, Fatemeh Fardsanei,
Volume 81, Issue 9 (December 2023)
Abstract
Background: Salmonella enterica subspecies enterica serotype Enteritidis (S. Enteritidis) is one of the leading causes of food-borne infections associated with the consumption of contaminated food products of animal origin in humans. gastroenteritis due to Salmonella is usually a self-limiting disease and does not require antibiotic therapy. However, antibiotic treatment for salmonellosis may be lifesaving for patients with severe infections.The objective of the present study was to examine antimicrobial resistance and determine its genetic basis in recently isolated S.Enteritidis strains.
Methods: During this study, in a cross-sectional descriptive study, 44 isolates of Salmonella enteritidis from human sources were investigated between September 2021 and September 2022.. After identification of the isolates using phenotypic and molecular methods by Multoplex-PCR, antibiotic resistance testing was performed according CLSI 2023. The strains were examined for the presence of qnrA,qnrB,qnrS and gyrA resistance genes by PCR.
Results:  In a cross-sectional descriptive study, 44 isolates of Salmonella Enteritidis from human sources were investigated between September 2022 and September 2023. 100% of the strains were sensitive to imipenem and meropenem, and the sensitivity to the antibiotics ceftriaxone, ceftazidime, and cefotaxime were 93.2%, 90.9%, and 94.1%, respectively. 81.8% of isolates were sensitive to cotrimoxazole, sensitivity to ampicillin was 84.1%. Only 9.1% of isolates were sensitive to ciprofloxacin. Based on MIC results, 16 isolates had MIC between 0.002 and 0.064 and were placed in the sensitive area. 28 isolates had MIC between 0.125 and 0.5 and were placed in the area of reduced sensitivity. None of the strains resistant to disk diffusion method were resistant to MIC method. qnrA, qnrB and qnrS genes were not observed among ciprofloxacin resistant strains. All nalidixic acid resistant strains had gyrA gene.
Conclusion: In general, it was shown in this study that the resistance to the fluoroquinolone family is increasing among Salmonella Enteritidis isolates. On the other hand, we see a decrease in the sensitivity and prevalence of strains resistant to broad-spectrum cephalosporins among serovar Enteritidis, which is the drug of choice for extraintestinal infections.

Jafar Hassanzadeh, Haleh Ghaem Maralani , Fatemeh Jafari , Aboubakr Jafarnezhad,
Volume 81, Issue 11 (February 2024)
Abstract
Background: It is necessary to examine different dimensions of psychometrics in different sciences, and paying attention to the accuracy and precision of the results can lead to the construction of reliable and valid tools; In this article, exploratory factor analysis has been done using SPSS software, version 26.
Methods: This research was a brief report that was conducted between 30 January 2023 to 10 October 2023. Reliability means reproducibility and continuity of results in the same conditions, and validity means matching the test with the purpose for which it was designed. Validity includes face, content, criterion and construct validity. To determine construct validity, various methods are used including: convergent validity, divergent validity, internal consistency and factor analysis. Factor analysis is a method that aims to simplify a complex set of data and allows researchers to find a specific pattern among many variables and complex relationships between them which includes exploratory factor analysis and confirmatory factor analysis. Exploratory factor analysis is a statistical technique that is used to estimate hidden factors or variables and reduce the large number of variables.
Results: exploratory factor analysis is a statistical method that is used by reducing the number of variables and exploring the underlying structure of a large set of variables with the aim of discovering factors or hidden variables, and its basic assumption is that any variable may be related to any factor. It tries to use factor loadings to discover the factorial structure of the data and by identifying the basic structures, grouping the factors by considering the common meaning of the variables.
Conclusion: Reliability means repeatability and validity of the degree of accuracy of the results which are measured through different methods. Exploratory factor analysis uses construct validity measurement methods to simplify the data and provide more reliable and valid tools, so it is very important to pay attention to the accurate and correct measurement of the results in the validation of health system tools.

Application of bone cements based on ceramic and polymer in orthopedic surgeries: a review article
Naeemeh Kalali, Sogand Mirshah, Mohammad Hossein Ebrahimzadeh , Bibi Fatemeh Kalalinia, Ali Moradi, Azar Gharib, Nafiseh Jirofti ,
Volume 81, Issue 12 (March 2024)
Abstract
For over 50 years, bone cement has been used to strengthen artificial joints like hip, knee, shoulder, and elbow joints. The main purpose of bone cement is to fill the space between the prosthesis and the bone. This absorbs the forces on the joint by creating an elastic area. Besides ensuring the long-term stability of the artificial implant, it also improves the damaged bone. Polymeric bone cement consists of a polymer matrix known as polymethyl methacrylate (PMMA) and a liquid monomer called methyl methacrylate (MMA). When these two components are mixed, a free radical polymerization reaction occurs, leading to the cement's hardening at the place of use. The properties of bone cement, such as mechanical strength, biocompatibility, and handling characteristics, can be adjusted by combining the effective polymerization parameters. However, there are some challenges, such as heat generation during polymerization.
Ceramic bone cement is a composite material of ceramic particles dispersed in a polymer matrix, including calcium phosphate and calcium sulfate. The ceramic particles provide strength and bioactivity, while the polymer matrix enhances the transport properties of the cement. This combination results in a mechanically stable, bone-conductive, and biocompatible cement. Moreover, ceramic bone cement can be engineered to release therapeutic agents, such as antibiotics or growth factors, to prevent infection and foster bone regeneration. Ceramic bone cement is a promising alternative material for bone cement in joint replacement. However, more research and development are required to optimize the properties of bone cement and overcome the challenges associated with its use. With continued advancements in biomaterials, ceramic and polymer bone cement could revolutionize the field of orthopedic surgery and improve patient outcomes. Recent research has focused on developing new bone cement with improved properties like bioactivity, antibacterial activity, and drug delivery capabilities. These developments aim to enhance the performance of bone cement and remove the current limitations in orthopedic applications. In this review study, we will focus on the types of bone cement, their mechanical, biological, and structural properties, and how to optimize them.

Lida Saeed, Niusha Bahmanpoor, Robabe Hosseinisadat, Fatemeh Karami Robati ,
Volume 81, Issue 12 (March 2024)
Abstract
Background: One of the factors affecting the outcome of pregnancy is the primary body mass index (BMI) and the amount of weight gain during pregnancy. This study aimed to check the relationship between mother's initial body mass index and weight gain in pregnancy with pregnancy outcomes.
Methods: This cross-sectional study was conducted on 455 pregnant women referred to Afzalipour Hospital in Kerman, Iran, from August 2021 to August 2022. These pregnant women were included in the study through easy and accessible sampling. The mother's initial weight was recorded through the mother's health card. The height of the mother was measured using a standard meter and the final weight of the mother before delivery was measured using a standard scale available in the department. Other information of the mothers was extracted from their records. Weight gain during pregnancy and initial body mass index were calculated and divided into four categories, less than normal, normal, overweight and obese. Maternal-fetal complications were included in the information registration form. Descriptive and analytical statistical methods and SPSS version 24 software were used to analyze the data.
Results: The average age of women was 27.56±6.82 years. Body mass index of more than 40% of them (44.4%) was normal (19.8-26) and more than 45% of them were overweight 11.5-16 (45.5%). There was a significant relationship between initial body mass index and weight gain during pregnancy (P=0.001), gestational diabetes (P=0.001) and newborn weight (P=0.019). There was also a significant relationship between weight gain during pregnancy with premature birth (P=0.001), vaginal delivery (P=0.001), gestational diabetes (P=0.001) and newborn Apgar (P=0.001).
Conclusion: High body mass index of the mother and weight gain during pregnancy can cause complications in the mother and the fetus. Therefore, prenatal care should be done more carefully and health care providers should place mothers who have abnormal body mass index and inappropriate weight gain in pregnancy in the high-risk group and under special care to minimize maternal and fetal complications.

Volume 82, Issue 1 (April 2024)
Abstract
Background: one of the most common and important complications of COVID-19 is cough. The present study was designed with the aim of comparing the effect of althaea officinalis and eucalyptus nebulizer on the severity of cough in COVID-19 patients.
Methods: in this randomized clinical trial, from January 2022 to June 2022, 36 patients with COVID-19 were selected and randomly divided into three groups. Next, the severity of cough was recorded two hours before the intervention based on the visual analogue (VAS) in both groups until the patient was admitted to the hospital, then, one cc aqueous extract of althaea officinalis with five cc Normal Saline for the althaea officinalis group and four cc aqueous extract eucalyptus whit five cc Normal Saline for the eucalyptus group, were nebulized once a day for 15 minutes. Two hours after the intervention, the intensity of cough was again recorded in two groups. This intervention continued until the hospitalization of the patients. No intervention was done for the control group. The data was analyzed with Spss software at a significance level of less than 0.05.
Results: In this study before the intervention, there was no statistically significant difference between the three groups in terms of cough intensity (p>0.05), but after the intervention on the second and third days, there was a statistically significant difference between the three groups in terms of cough intensity. The rate of reduction in cough severity in althaea officinalis group was higher than the other two groups (p<0.05).  Also, the results of Friedman's test indicated that althaea officinalis and eucalyptus nebulizers incense improved the severity of cough in patients over time.
Conclusion: the use of althaea officinalis and eucalyptus nebulizer improved the severity of cough in patients with COVID-19, but althaea officinalis nebulizer had a greater effect on cough severity compared to eucalyptus. It is suggested to use althaea officinalis nebulizer as well as eucalyptus as a treatment method along with other treatment methods.

Volume 82, Issue 1 (April 2024)
Abstract
Background: Maternal and neonatal complications in twin and multiple pregnancies are higher than in singleton pregnancies. The purpose of this study is to investigate maternal and neonatal outcomes in twin or multiple births.
Methods: In this descriptive and analytical study, 266 pregnant women with twins and multiples were selected in a goal-based manner who had medical records in Imam Khomeini Hospital in Ahwaz from March 2020 to March 2022. This study is based on the purpose of selection and then the required information was extracted from the archive department of Imam Khomeini Hospital in Ahwaz. A two-part checklist was used to collect data, and then the collected information was analyzed by descriptive and analytical statistical tests.
Results:  The observations of this study show that the highest frequency of the total number of births is from March 2020 to March 2021 (6729 people), while the highest ratio of the number of twin or multiple births to the total number of births is from March 2021 to March 2022 (4.63 percent). The frequency of stillbirths is the highest from March 2021 to March 2022 (62.96 percent). There is a significant difference in fetal complications of twin and multiple births, premature birth, low birth weight and intrauterine growth delay between twin and multiple births (P-value<0.05) and for fetal anomaly and death from March 2021 to March 2022. Comparison of the two years under study shows no significant difference was observed between twin and multiple births (P-value>0.05). Pre-eclampsia was observed in 7.8 percent for twin births and 6 percent for multiple births, which statistically has no significant difference between them (P-value=0.331) and for diabetes, placental abruption and placenta Previa. There is a significant difference between twin and multiple births (P-value<0.05).
Conclusion: The frequency of multiple pregnancy shows an increase compared to previous studies in Iran, and prevention of premature birth and careful monitoring of the fetus can improve the outcome of twin or multiple births.
