Abstract
Background: Screening is a cost-effective method for prevention, early detection of the disease and reducing the burden of the third deadliest cancer in the world, i.e. colorectal cancer. This study aimed to analyze the cost-effectiveness of colonoscopy screening compared to sigmoidoscopy for colorectal cancer in high-risk individuals in Iran.
Methods: This economic evaluation study was conducted using the cost-effectiveness method between July 2016 and February 2017. Evaluation of the effectiveness of screening methods was done using a systematic review. Cost evaluation was also done using the costs obtained from the tariff approved by the Iranian Ministry of Health in 2015 for colonoscopy and sigmoidoscopy. Finally, the combined model of decision tree and Markov was used to evaluate the cost effectiveness. Incremental Cost Effectiveness Ratio (ICER) formula was used for cost effectiveness analysis considering the final outcome of 5-year survival of high-risk individuals. Excel and TreeAge software were used for data analysis.
Results: The effectiveness of sigmoidoscopy and colonoscopy in increasing 5-year survival is 11 and 15.7%, respectively, and colonoscopy screening is 4.7% more than sigmoidoscopy. The cost of colonoscopy and sigmoidoscopy screening was calculated as 1000 and 19920 billion Rials, respectively. Based on cost-effectiveness analysis, the cost of treating patients in the case of screening with colonoscopy and sigmoidoscopy is lower than without screening. The ICER ratio of colonoscopy and sigmoidoscopy compared to no screening was -4/441/389/160 and -4/757/954/940 Rials respectively, and colonoscopy compared to sigmoidoscopy was -3/699/785/880 Rials, respectively. Finally, the use of colonoscopy leads to spending 3/699/785/880 Rials less in exchange for obtaining 4722 additional survivals with the prevention of colorectal cancer compared to sigmoidoscopy.
Conclusion: Screening by colonoscopy and sigmoidoscopy methods are effective in reducing the incidence and death of colorectal cancer compared to no screening. Screening by colonoscopy is a dominant option for the high-risk population in Iran. Colonoscopy screening is more cost effective compared to sigmoidoscopy. However, decisions about colorectal cancer screening and screening methods depend on local resources and personal preferences.

Volume 81, Issue 9 (December 2023)
Abstract
Background: Foot posture is proposed as an important factor that may affect the lower limb alignment. Variations from the normal foot posture may contribute to musculoskeletal injuries of the lower extremity especially knee joint. Considering variations in foot posture and knee joint alignment, this study aimed to assess and compare pennation angles of the vastus medialis oblique (VMO), vastus medialis (VM) and vastus lateralis (VL) in women with pronated foot posture and normal ones.
Methods: This observational, case-control study was carried out on 31 women with pronated foot posture (foot posture index: 6-12) and 31 women with normal foot posture (foot posture index: 0-5) in the age range of 18 to 35 years old.  Participants were recruited from female students of university communities using Non-probability Sampling method. Sampling was carried out from September 2019 up to February 2020 at the biomechanics laboratory of rehabilitation faculty of Tehran University of Medical Sciences. The pennation angle of VMO, VM and VL muscles was measured by using two dimensional. B-mode ultrasound imaging (USI) .A 7.5MHz linear transducer with 50mm footprint was used for the measurements. The ultrasound images were analyzed using Image J software. Three longitudinal scans were captured for each muscle pennation angle while the probe removed between each scan.
Results: The results of this study showed that there is no statistical significant difference between the pennation angles of  VMO, VM and VL in women’s foot posture compare to the normal ones (P>0.05).
However, the results of intraclass correlation coefficient (ICC) of USI measurements showed “good” intrarater reliability for VMO (ICC=0.88), VM (ICC=0.87) and VL (ICC= 0.77) pennation angles.
Conclusion: Based on the results of this study, the pennation angle of knee extensor muscles (VMO, VM, and VL), which was measured in non-weight bearing, is not different in young women with pronated foot compared to the normal ones. In addition, USI demonstrated good reliability for measuring VMO, VM and VL pennation angles.

Abstract
Background: Cytomegalovirus (CMV) stands out as a significant contributor to congenital viral infections, exhibiting a prevalence ranging from 40% to 90%. Cytomegalovirus has different effects on people, such that it appears without symptoms in people with a healthy immune system, but it leads to severe symptoms in infants and those with a weak immune system. To comprehend the disease's societal prevalence, seroepidemiological investigations are imperative. This study aims to ascertain the serum prevalence of cytomegalovirus and explore potential correlations between age, sex, and the prevalence of CMV in patients attending Shahid Motahari Clinic in Shiraz
Methods: A cross-sectional descriptive study was undertaken on 2,469 individuals who assessed their cytomegalovirus antibody levels between March 2019 and February 2023 at Shahid Motahari clinic in Shiraz. The ELISA method was employed to evaluate CMV, and the obtained data were analyzed using SPSS version 19 software. Chi-square tests and Fisher's exact test were applied to examine the correlation between positive antibody results and age as well as gender.
Results: Among the 2469 surveyed people, 658 people (26.65%) were men and 1811 people (73.35%) were women. Based on ELISA test, antibody titer was reported positive in 1157 people (46.9%), including 315 men and 842 women, and 1312 people (53.1%) had negative antibody titer. The highest number of positives is related to IgG, and in IgM, the test results are mostly negative. IgM prevalence showed no gender correlation but demonstrated a significant association with patient age. Meanwhile, IgG prevalence exhibited significant relationships with both age and gender
Conclusion: Considering that the city of Shiraz is considered as one of the centers of treatment in the country and a large number of patients from all parts of the country and even neighboring countries come to this city for treatment and especially for the purpose of organ transplantation; also with Considering the 46.9% prevalence of CMV infection in the region, it is recommended to use preventive methods such as vaccine and immunotherapy against CMV infection in patients

Abstract
Background: Lower gastrointestinal bleeding, a symptom that can become the cause of a life-threatening condition, has a 33 per 100,000 prevalence. The origin of lower gastrointestinal bleeding in most cases is the small intestine, colon, or anorectal parts. Surgical consultation in patients with gastrointestinal bleeding is one of the most necessary measures so that the patient can be treated at the appropriate stage with a greater chance of success before reaching shock. In the case of uncontrolled gastrointestinal bleeding, surgery is recommended as soon as possible when endoscopic and radiological treatments are not possible or effective.
Case Presentation: In this article, we present a case of uncontrolled lower gastrointestinal bleeding in a 50-year-old patient who was admitted to Imam Khomeini Hospital in Tehran on December 15, 2021. Despite performing appropriate paraclinic measures such as sonography, endoscopy, and colonoscopy the gastrointestinal bleeding origin was not determined. On the other hand, our investigations showed that she had liver cirrhosis. Due to the instability of the patient's condition due to continued lower gastrointestinal bleeding, the medical team decided to perform surgery. The surgeon noticed that the origin of the bleeding was a vascular entanglement at the small intestine-navel junction, and the procedure involved segmental excision of the small intestine.
 Conclusion: In cirrhotic patients, lower gastrointestinal bleeding is an emergency condition, and if the source of the bleeding is not accessible via endoscopy or colonoscopy, diagnosing and treatment become extremely difficult. Computed tomography angiography and subsequent surgery are effective approaches for diagnosing and treating these conditions. When lower gastrointestinal bleeding is uncontrolled, exploratory laparotomy should be considered. Due to the unknown origin of bleeding, exploratory laparotomy may not be successful, so using endoscopy during surgery can help to diagnose the location of the lesion in these cases; However, in some cases despite all measures, the source of bleeding may not be determined, in these case the rate of rebleeding after surgery will be high.

The relationship between stroke and physical activity: effects of exercise on prevention and rehabilitation: a review article
Hamid Reza Choobdari , Mohammad Ali Gharaat ,
Volume 81, Issue 10 (January 2024)
Abstract
Stroke is a medical condition in which occluded blood flow to the brain causes cell necrosis. The main types of stroke are ischemic (due to lack of blood flow with much higher prevalence) and hemorrhagic (due to bleeding with low prevalence). Ischemic stroke is caused by the reduction of blood to the brain tissue or complete occlusion of brain vessels by a blood clot following arterial plaques rapture of cerebral arteries due to atherosclerosis, cerebral myocardial infarction and small vascular lesion infarction. Inflammatory reactions, increased oxidative stress, cell death and autophagy are the most aggravating factors in this condition. Instead, hemorrhagic stroke is caused by spontaneous intracranial hemorrhage and subarachnoid hemorrhage, highly common in men. To prevent the possible causes of stroke, investigators attempted to study about the ways that may decrease the risk factors such as trauma, high arterial hypertension, alcohol, low-density lipoprotein and glycerides, tobacco and drugs. Physical activity is a potent inhibitory factor which reported to be effective in prevention of stroke and post-stroke rehabilitation. Aerobic, combined or strenuous activities protect brain tissue by balancing apoptotic and anti-apoptotic pathways, stimulating angiogenesis, reducing oxidative stress, increasing antioxidant activity, optimizing Integrity and preservation of the blood-brain barrier, improving nerve functions and preventing neuronal death. The mechanisms involved in rehabilitation after ischemic stroke with physical activity mostly refer to improved dendrites and synapses, synaptic flexibility, regulation of inotropic receptors with glutamate, increased BDNF, GAP43 and insulin-like growth factor. In patients with cognitive impairments following acute ischemic stroke, high intensity exercise improves processing timing and attention allocation, self-independence, walking ability, aerobic power and reduces memory degradation. Moreover, early start of physical activity after ischemic stroke inhibits the initial physiological response to stroke and prevents optimal recovery. In contrary, reports show positive effects of onset of physical exercise a day after stroke. In hemorrhagic stroke, exercise reduces systolic blood pressure, moderates resting blood pressure via parasympathetic regulations and triggers angiogenesis in the nervous system. Light to moderate or long-term physical training is recommended in comparison to short-term high-intensity training. In addition, early onset of physical activity during recovery after stroke may be beneficial.

Volume 81, Issue 10 (January 2024)
Abstract
Background: Today, Methicillin-Resistant Staphylococcus Aureus (MRSA) has become one of the public health concerns due to its resistance to antimicrobial drugs, and this problem makes treating patients with infections caused by this bacterium difficult. Infections caused by methicillin-resistant Staphylococcus aureus (MRSA) strains are pervasive in both community and hospital settings, primarily attributable to Staphylococcus aureus' capacity to colonize areas like the nose or skin. In this study, with the aim of comparing phenotypic (disc diffusion method) and genotypic (PCR) methods, to detect methicillin-resistant Staphylococcus aureus isolated from patients of hospitals under supervision of Tehran university of medical sciences, and also detection of nor A, that is the one of the most important genes in efflux pump cluster genes.
Methods: The present research was a cross- sectional study that was conducted from February 2022 to September 2023. In this research, 43 isolated strains of Staphylococcus aureus from wound discharge and blood samples, were collected from different departments of Tehran hospitals and had submitted to the research laboratory of the school of allied medical sciences in Tehran university of medical sciences. After identifying the strains, the resistance of the isolates to 14 types of antibiotics was checked by disk diffusion method.
Results: Staphylococcus aureus diagnostic tests including gram staining on colonies, catalase, coagulase, DNase tests were performed and it was found that all strains were Staphylococcus aureus. In the next step, all samples were resistant to Cloxacillin by disc diffusion method, and the presence of mec A gene in them was confirmed by PCR method, thus the presence of MRSA strains was confirmed from the genotypic point of view. Of the 43 Staphylococcus aureus strains, 26 samples were identified as having the nor A gene by PCR and electrophoresis.
Conclusion: The results of the present research have shown that the prevalence of Staphylococcus aureus bacteria in hospital samples is significant and resistance to methicillin and ciprofloxacin has increased in the strains of this bacteria.

Ameneh Javanmard, Alireza Salehan,
Volume 81, Issue 10 (January 2024)
Abstract
Background: Coronaviruses were discovered in 1960. Large-sized living organisms from the Coronaviridae family, with single-stranded RNA of animal origin. Coronaviruses in humans can cause mild respiratory illness or severe respiratory illness. In 2020, the World Health Organization declared COVID-19 a global pandemic. The aim of this study is to use the Jaccard similarity coefficient to determine the similarity of COVID-19 behavior patterns in different seasons of the year.
Methods: This study used machine learning systems and similarity metrics to determine the behavior pattern of COVID-19 in different seasons of the year. The location of research was the Mousa ibn Ja'far Hospital in Mashhad, and the time was from May 2020 to August 2021. The symptoms of affected patients were compared with the compiled dataset, and the similarity of patients was prepared in a similarity matrix, and the Jaccard correlation coefficient was calculated on the data. Finally, the analysis of strains from the beginning of emergence to the latest strain was examined. The performance indicators of the algorithm in the Jaccard similarity method showed a recall metric with a value of 0.94, a precision metric with a value of 1, an F1 score with a value of 0.86, and remove accuracy metric with a value of 0.76. The most important factors in the investigation include white blood cells, platelets, RT-PCR, CT SCAN, shortness of breath, fever, SPO2, and respiratory rate.
Results: The transmission of the COVID-19 virus depends on several factors, including human interaction. The evidence of the collected data shows that people with COVID-19 have low lymphocyte count and it is very consistent with the results of recent studies. Due to the lack of a dataset, a comparative study was conducted and a dataset was collected.
Conclusion: This study, leveraging machine learning algorithms, identified a clear seasonal correlation in the spread of COVID-19. Considering geographical and seasonal variations among patients, distinct symptoms were observed in each season corresponding to the prevalent strain during that period.

Volume 81, Issue 11 (February 2024)
Abstract
Background: Developmental disorders in children include a group of problems and limitations in learning and acquiring specific skills of each age group. The term global developmental delay is used to describe developmental disability in children under five years of age, which is in at least two areas of major development. Neuroradiological imaging such as brain MRI provides important information for physicians. The purpose of this study is to determine the role of brain MRI in predicting the clinical outcome of global developmental delay in children.
Methods: In this cross-sectional study, from 79 - from September 2013 to September 2018 at Motahari Clinic of Shiraz University of Medical Sciences, Shiraz Iran - eligible children with developmental disabilities, 37 patient who had brain MRI were selected as a sample and children scores in five ASQ clinical areas and MRI findings were reviewed and compared. Patients suffering from metabolic, genetic, trauma, infection and neoplasms problems and diseases were excluded from the study.
Results: Out of 37 patients studied, 23 were female and 14 were male with a dispersion of three 3 to 60 months of age. 31 of these children had at least one abnormal finding in brain MRI images and the other six were completely normal. In relation to the imaging findings, the highest frequency is related to abnormal head circumference with a prevalence of 54% and the lowest frequency is related to abnormal myelinization with a prevalence of 10.8%. Results of MRI findings correlation with developmental domains demonstrated that Children with white matter disorder on MRI show severe gross motor abnormality (P<0.049) and who had MRI finding of cortical problems suffer from developmental delay in fine motor area. (P<0.001).
Conclusion: Considering the mentioned findings; brain MRI can be a useful diagnostic tool in children with developmental delay and also focusing on the developmental area that is more likely to be affected, MRI can help with treatment and rehabilitation process of these children in the future.

Abstract
Background: Diabetes is known to be linked with a high risk of liver stiffness in non-alcoholic fatty liver patients. Previous studies have faced challenges in examining the association between prediabetes and liver stiffness. This study aimed to compare liver fibrosis in diabetes and prediabetes patients.
Methods: This cross-sectional descriptive study was conducted on patients with diabetes and prediabetes who were referred to Imam Khomeini Hospital in Ahvaz from March 2022 to March 2023. The study aimed to clear the relationship between liver stiffness and age, gender, BMI, AST, ALT, ALKP, Bilirubin, and the type of treatment. The normality of quantitative variables was checked using the Kolmogorov-Smirnov test. The chi-square test examined two qualitative variables with more than two levels.
Results: Out of the total participants, 53 people (63.9%) had diabetes, while 30 people (36.1%) had prediabetes. There was a significant difference between the mean severity of liver fibrosis in diabetic and pre-diabetic patients (P=0.014). The frequency of liver stiffness in all levels except in the group with mild or no fibrosis (F0-F1) was higher in diabetic than pre-diabetic patients. In both diabetes and prediabetes groups, there was no significant relationship between gender, age, BMI, ALT, and ALKP with liver fibrosis. However, there was a significant direct relationship between HbA1C% and liver fibrosis (P≥0.003) in both groups. In diabetic patients, a significant relationship between FBS and liver fibrosis was observed (P=0.001). In pre-diabetic patients, significant direct relationship was seen between the severity of liver fibrosis and AST levels (P=0.026).
Conclusion: Diabetic patients showed a higher severity of liver fibrosis compared to pre-diabetic patients. No statistically significant relationship was seen between liver fibrosis and age, sex, body mass index, ALT, and ALKP in both groups. Additionally, both diabetes and prediabetes groups showed significant relationship between liver fibrosis and HbA1C (P≥0.003). Prediabetes was also found to be associated with an elevated risk of liver fibrosis.

Volume 81, Issue 11 (February 2024)
Abstract
Background: The emergence of thrombolytic drugs has opened new horizons in the treatment of patients with acute ischemic stroke, and this study was conducted with the aim of evaluating the barriers of receiving tissue plasminogen activator in patients with acute ischemic stroke in Imam Khomeini Hospital of Urmia.
Methods: This descriptive-analytical, cross-sectional study was conducted from April 21, 2015 to March 19, 2016 on patients with acute ischemic stroke referred to the emergency department of Imam Khomeini Hospital in Urmia using census sampling method. To collect data, a checklist containing demographic information was used. After collecting the data, it was entered into SPSS 18 and analyzed with the help of descriptive statistics.
Results: In this study, the results showed that out of 100 patients, most of the participants were male (58%)58 and the rest were female, and the average age was 63.71±17.3 years, and 86% were in the age range of 18-80 years, which was the appropriate age to receive or thrombolytics. and the rest were over 80 years old. The fastest visit time was 25 minutes and the latest was 10080 minutes (168 hours). Among these 40 people, only four people (40%) were in the golden time period of thrombolytic drug, i.e. Three hours from the onset of symptoms to the final evaluation. Among the four people who were placed in the golden time, in 50% of the cases there was a history of taking anticoagulants, in 25% a history of head injury, in 50% of the blood sugar less than 50 and finally 1 person (25% of the people placed in the golden time) that is, 1% of all patients were eligible to receive rtPA. About 24% of patients had NIHSS<4 and 2% had NIHSS>25, and the average number obtained was 10.
Conclusion: The most important obstacle in the timely initiation of thrombolytic therapy is the delay in visiting the emergency room. Therefore, public education in order to improve the level of general awareness of the society can be effective in reducing this time delay.

Hossein Eskandari, Faramarz Sohrabi , Adeleh Rezagholizadeh Shirvan , Mohammad Asgari , Neda Shahvaroughi Farahani ,
Volume 81, Issue 12 (March 2024)
Abstract
Background: The experience of existential distress, along with other forms of distress, is one of the common experiences in end-of-life patients. Therefore, the purpose of this research is to review related studies and conceptualize existential distress in palliative care of cancer patients.
Methods: This study was a systematic review, which was conducted from May 1 to July 31, 1402 at Allameh Tabatabai University and search strategy was written and performed in MEDLINE, Web of Science/PubMed and Scopus databases from the beginning of 2003 to the end of 2022. The inclusion criteria included all quantitative, qualitative, mixed and review studies that focused on the experience of adult patients. Lack of access to the full text of the article and studies in non-English language, clinical trial (randomized and non-randomized), letter to the editor, case report and protocol were excluded from the list of studies. After removing duplicate articles, two research authors reviewed the studies independently according to the inclusion and exclusion criteria, and the differences between them were resolved by discussion.
Results: After searching, screening and selecting articles based on inclusion and exclusion criteria, finally 22 articles were included in the study, of which three were review articles, eight were quantitative and 11 were qualitative. Terminally cancer patients experience existential distress, and the data are significant for estimating the prevalence of these symptoms, especially in the severe category. In addition to examining the prevalence of this symptom, patients have described their experience of existential distress in several categories: Feelings of loneliness and isolation (or loss of support system), relationship concerns (concerns about family, changes in relationships, and conflictual relationships), loss of control/autonomy (physical control, cognitive and emotional control), burden on others, loss of sense of continuity (loss of roles, pleasurable activities and sense of self), uncompleted life tasks, hopelessness/helplessness, dissolving of the future, uncertainty and frightening ambiguity, feeling guilt/ regret about the past, lack of meaning, inevitable thoughts of death.
Conclusion: It seems that the themes raised beyond cultural differences show the universal human suffering, whose accurate conceptualization can help to develop effective therapeutic interventions to reduce existential distress.

Abstract
Background: Fatty liver disease is the most common cause of chronic liver diseases in the world, which can cause cardiovascular diseases, so this research aims to scrutiny a period of intense intermittent sports activity and growth hormone perfuse on cardiac mitochondrial PGC1α and some indicators of oxidative stress in mice with liver damage.
Methods: The present research was conducted from September 2022 to March 2023 in the specialized physical training laboratory of Ferdowsi University of Mashhad. The statistical population was twenty one adult male Syrian mice with an average weight of twenty three grams. The sports activity protocol was adopted for fifty-six days using the special video recorder for rodents. The intense interval training program was carried out in the form of ten one-minute repetitions and two-minute active rest, so that the total daily training time for each person was thirty minutes.The vaccination protocol includes the daily vaccination of somatropin injected intraperitoneally.
Results: The PGC1α levels were significantly higher in both the HIIT (P=0.02) and H- GH (P=0.03) groups collationed to the witness team. Moreover, the levels of SOD were considerably increased, in both the HIIT (P=0.05) and H-GH (P=0.005) team s compared to the witness team. Moreover, the levels of MDA were considerably decreased, in both the HIIT (P=0.007) and H-GH (P=0.04) teams compared to the witness team. The decrease in insulin resistance was significant only in the HIIT (P=0.05) team compared to the witness team and slightly increased in the H-GH (P=0.36) team but was not considered. The difference between HIIT and H-GH team (P=0.03) was also significant.The proportion of ALT/AST in both HIIT (P=0.02) and H-GH (P=0.03) teams had a significant decrease compared to the witness team. LDL/HDL proportion evidenced considered decrement at just in the HIIT team (P=0.01).
Conclusion: Intense intermittent sports activity was able to produce a more optimal response compared to GH peptide in improving NAFLD-related indices. Injection of this hormone single may have adverse outcomes on some indexes of this abnormality.

Abstract
Background: Psychosocial improvements of successful strabismus surgery have been reported in previous studies. But the effect of strabismus surgery on the emotional intelligence of patients is unclear. The aim of this study was to evaluate the effect of strabismus surgery on emotional quotient in patients referring to Imam Khomeini Hospital, Ahvaz.
Methods: This prospective interventional study conducted on patients underwent strabismus surgery in Imam Khomeini Hospital, Ahvaz during May 2021 to March 2022. A total of 38 patients between 8-37 years were included. Patients with previous surgery were excluded. All subjects were evaluated before and three months after successful strabismus surgery. Three months post-surgery the improvement of emotional quotient, self-esteem, body image, social anxiety and social avoidance were evaluated and compared with previous surgery. All data were analyzed by SPSS (V25). P-Value less than 0.05 was considered as significant level.
Results: 38 subjects including 18 males (47.4%) and 20 females (52.6%) were included. The mean age of patients was 18.11±9.33 years old. Our results showed that compared with before surgery, significant improvements were noted after surgery, within the emotional quotient subscales including self-awareness (P=0.016), self-regulation (P<0.0001), self-motivation (P<0.0001), empathy (P<0.0001), social skills (P<0.0001) and emotional quotient total score (P<0.0001). Further analysis revealed statistically significant improvements in body image (P<0.0001), social anxiety (P=0.004) and social avoidance (P=0.002). The result showed that the improvement of emotional quotient after strabismus surgery was significantly higher in the age group of less than 12 years (P<0.0001). No significant difference was fund between two  genders for emotional quotient subscales (P>0.05).
Conclusion: The results of this study showed a significant improvement in the psychosocial factors including emotional quotient, body image, social anxiety and social avoidance after strabismus surgery. This result suggests that beyond functional and cosmetic improvements, successful strabismus surgery can result in improved emotional quotient and social anxiety, with the greatest effect noted in younger patients.

Abstract
Background: One of the first-line treatments to prevent migraine attacks is Sodium Valproate. "Booali Daroo" pharmaceutical company has made a herbal capsule called Sodae based on traditional Iranian medicine. The aim of this study is to compare the effect of Sodae and Sodium Valproate on migraine headaches.
Methods: This two-center, double-blind, randomized clinical trial was conducted between December 2021 and July 2022 in the cities of Kermanshah and Hamadan. In this study, 76 migraine patients were randomly divided into two groups. One group received routine medication with Soda capsules and the other group received routine medication with Valproate capsules. Tow group were examined and followed up for three months. Data related to demographic and clinical information of patients were collected and entered into SPSS software version 25. Data analysis was done with a significance level of 0.05.
Results: Overall, 76 patients assessed (36 in the Sodae group and 40 in the Valproate group). The reduction of headache indicators was not significant between the two groups; in such a way that: the frequency (7.49±6.1 vs. 5.75±4.5, P=0.183), the severity (5.66±1.6 vs. 6.34±1.8, P=0.089), the duration of attacks (23.48±30.5 vs. 32.35±32.6, P=0.069), and the Migraine Disability Assessment Score (53.94±77.3 vs. 95.94±104.2, P=0.061) respectively in Valproate and Sodae. Examining different classes of MIDAS score showed that at the end of the study compared to the beginning of the study, the number of people with severe disability decreased significantly and their disability changed from severe disability to lower degrees of disability (P<0.05). The frequency of side effects was not significantly different between the two groups (12 patients (35%) in Sodae versus 21 patients (55%) in Valproate, P=0.090).
Conclusion: In terms of frequency, intensity and duration of migraine headaches as well as side effects, there was no significant difference between Sodium Valproate and Sodae groups.

Results: In this study, the results showed that in terms of the frequency of triage level, 5.4% was level one, 65.6% was level two, 26.3% was level three, 2.7% was level four and there was no disease in level five. In terms of shift, 22.5% visited the hospital in the morning shift, 27.6% in the evening shift and 49.9% in the night shift. The average EDWIN index was 2.7±0.75 on holidays and 5.9±4.6 on non-holiday days. Although emergency room congestion was more on non-holiday days, this difference was not statistically significant (P=0.15). Also, the average of EDWIN in the morning shift was 2.5±2.3, in the evening shift it was 0.71±2.16 and in the night shift it was 9.7±5.8 and even though the average of EDWIN in the night shift was higher than in the evening and night shifts, this difference was not statistically significant (P=0.06).
Conclusion: The results of the present study indicated that on most of the investigated days, the emergency room was evaluated as crowded based on the EDWIN criteria. Also, there is no significant difference between the busyness of the emergency room according to the holiday or working day, as well as the morning, evening and night shift.

Caring limbo for nurses, caring for patients with delirium: a letter to the editor
Reza Abdollahi , Yaser Moradi,
Volume 81, Issue 12 (March 2024)
Abstract
سردبیر محترم
دلیریوم (Delirium) یک سندرم روانی- عصبی شناخته شده است که با اختلال در سطح هوشیاری و توجه بیمار مشخص می‌گردد. علایم آن در مدت زمان کوتاهی بروز کرده و معمولاً با نوسان علایم در طول شبانه‌روز همراه است. این اختلال از جمله دلایل اصلی ایجادگیجی در بیماران بستری در بیمارستان می‌باشد که می‌تواند به‌صورت حالاتی از کم‌تحرکی، بیش‌فعالی و یا ترکیبی از هر دو، در بیماران دیده شود.1
پرستاران در تعیین و کنترل دلیریوم در جایگاه مهمی قرار دارند. با توجه به اینکه آنها از مراقبین اصلی بیماران به‌شمار می‌آیند، مشاهدات منظم و به‌موقع آنان باعث تشخیص سریع علایم اصلی دلیریوم از جمله عدم توجه و نوسانات سطح هوشیاری در بیماران می شود.2
با این وجود دلیریوم اغلب اوقات به‌دلیل کمبود دانش و سطح آگاهی پرستاران تشخیص داده نشده و یا نادیده گرفته می‌شود. ماهیت متغیر دلیریوم، همپوشانی علایم آن با علایم بیماری فراموشی، کمبود پروتکل‌های ارزیابی و تشخیصی در بیمارستان‌ها و ضعف کارکنـان تـیم درمـان در نحوه استفاده از ابزارهای شناسایی دلیریوم، از جمله دلایل نقص در تعیین ایـن اختلال محسوب می‌شود.3
علیرغم آگاهی پرستاران از وجود دستورالعمل‌های تدوین شده برای کنترل دلیریوم، پرستاران به دلایلی همچون بار زیاد کاری، عدم آشنایی با پروتکل‌های مراقبتی و نبود انگیزه از اصول مراقبتی و دستورالعمل‌ها به‌صورت کامل تبعیت نمی‌کنند.4
از سوی دیگر، مراقبت پرستاران از بیماران مبتلا به دلیریوم تحت تاثیر ساختار آموزش پرستاران و فرهنگ مراقبت در سیستم درمانی حاک بر سازمان انجام می‌شود. لذا ضعف پرستاران در تشخیص و مراقبت‌های پرستاری موثر و با کیفیت از دلیریوم می‌تواند ریشه در نقص پیشینه سیستم آموزش داشته باشد.5 ماهیت ویژه و منحصر به فرد دلیریوم و عوامل متعدد تاثیرگذار بر آن، پرستاران را در تشخیص و به‌خصوص مراقبت از این بیماران با چالش‌های فروانی روبه‌رو کرده است که از جمله آنها می‌توان به موارد زیر اشاره کرد:
1- بروز رفتار لجام گسیخته در بیمار مبتلا به دلیریوم که باعث بی‌قراری در بیمار شده و به‌دلیل بروز رفتارهای پرخاشگرانه احتمال صدمه و آسیب به بیمار و پرستار بیشتر می‌گردد.6
2- غفلت اعضای خانواده بیمار در بروز و یا تشدید دلیریوم، تغییر ناگهانی شرایط جسمی و روحی بیمار مبتلا به دلیریوم و همچنین نمایش رفتارهای غیرمعمول در بیمار باعث می‌شود تا اعضای خانواده بیمار نتوانند شیوه صحیحی را برای ایجاد آرامش در بیمار خود انتخاب نمایند.7
3- عدم آگاهی اعضای خانواده در مورد ارایه مراقبت‌هایی مطلوب و رفع نیازهای پایه مانند غذا دادن، اجابت مزاج و غیره عاملی برای بروز دلیریوم می‌باشد. تنهایی بیمار در بیمارستان و یا همراهی افراد غیرآشنا در کنار بیمار می‌تواند زمینه بروز دلیریوم را بیشتر کند.8
4- ارتباط ناکارآمد نیز می‌تواند سبب بروز دلیریوم شود. در صورت برقراری ارتباط درست با بیماران می‌توان نیازهای بیماران          را ارزیابی کرد و عوامل مسبب دلیریوم ر ا برطرف نمود. براساس منابع علمی، یکی از مهمترین عوامل مربوط به کیفیت مراقبت          و ایمنی بیمار، مهارت‌های ارتباطی بین پرستاران و بیمارانشان می‌باشد.9
5- ترس از ناشناخته‌ها در قالب تـرس بیمار از محیط درمانی، پرسنل و فرایندهای درمانی نیز می‌تواند به‌عنوان ریشه‌های ظهور دلیریوم شناخته شوند.
6- بی‌ثباتی محیط در بروز دلیریوم نقش دارد. دلیریوم در محیط آرام و بی‌سر و صدا مانند بخش CCU بیشتر بروز می‌کند، بروز دلیریوم در بیماران بستری در بخش‌های پر سر و صدا، شلوغ و پر رفت و آمد را نیز می‌توانند مورد انتظار باشد.10
باتوجه به چالش‌های ذکر شده، به‌دلیل ماهیت چند بعدی و پیچیده دلیریوم، مراقبت از این بیماران را برای پرستاران می‌توان به برزخ مراقبتی تشبیه کرد که با نوعی ابهام و سردرگمی همراه است.  لذا می‌توان با اقداماتی همچون برگزاری دوره‌های آموزشی ویژه‌ای بـرای پرستاران در مورد دلیریوم، ابزارهای تشخیصی آن و روش‌های کنترل و پیشگیری آن، این مشکل را تعدیل کرد. از سوی دیگر با توجه به نقش پرستاران در پیشگیری و کنتـرل دلیریـوم، ضروری اســت گایدلاین‌ها و برنامه‌های پیشگیرانه از دلیریوم مطابق با گایدلاین‌های بین‌المللی تدوین و مورد استفاده پرستاران قرار گیرد.

Abstract
Background: Given the significance of patient care in obstetrics and gynecology, we aimed to assess the satisfaction of Tehran University of Medical Sciences residents with their training program in this field.
Methods: In this cross-sectional descriptive study, 77 obstetrics and gynecology residents from the first to fourth year at Tehran University of Medical Sciences participated with informed consent, adhering to ethical principles, from April to October 2023 across four teaching hospitals: Imam Khomeini, Shariati, Mohib Yas, and Arash.The researcher developed a questionnaire consisting of 62 online questions, including 15 demographic questions and 47 related to satisfaction. Most of the questions are statements with five response options: strongly agree, agree no opinion, disagree, and strongly disagree. Each criterion was assessed and classified on a scale from one to five. The assistants' satisfaction levels were assessed in various areas, yielding an overall score of 47-235. Scores above 70% indicate high satisfaction, 50-69% reflects average satisfaction, and below 50% signifies dissatisfaction. It's important to clarify that the areas include clinics, with specific focus on rotation shifts for assistants in gynecology, oncology, prenatal care, and infertility. Data analysis was conducted using SPSS software, Version 22. Descriptive statistics included the median and range for continuous variables (number of surgeries and satisfaction scores) and frequency and percentage for nominal variables (quality of satisfaction) across three defined levels of desirability: appropriate, relatively appropriate, and unfavorable.
Results: Satisfaction with the number of surgeries and educational quality at Imam Khomeini Hospital was higher than at other hospitals (P=0.07). Significant differences were noted in the gynecology and pelvic surgery departments, with residents at both Imam Khomeini and Arash hospitals reporting greater satisfaction in gynecology (P=0.018) and pelvic surgery (P=0.036). Additionally, regarding the conference program and educational mornings, Shariati Hospital reported a higher level of satisfaction in this area (P=0.47).
Conclusion: The satisfaction scores in various areas indicate that 64.5% of assistants at Imam Khomeini Hospital rated their educational status as appropriate, while 60% at Arash Hospital rated it as relatively good, and 25% at Yas Hospital found it unfavorable.

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.
