Volume 81, Issue 10 (January 2024)
Abstract
Background: Exercise programs can lead to different physiological adaptations, but the effects of low-volume, low-frequency HIIT protocols with varying interval structures have not been thoroughly investigated. This study aimed to explore the impact of HIIT with high compression (HC) and low compression (LC), with or without berberine (BBR) supplementation, on hematological parameters in pre-diabetic men.
Methods: This semi-experimental study was conducted between October and December 2021 at Mazandaran University. Fifty-four overweight/obese men with a mean age of 48.6±6.6 years, a body mass index of 30.7±7.3 kg/m², and a body fat percentage of 34.4±4.3% were randomly and equally divided into one of six groups: HC, LC, HC+BBR, LC+BBR, BBR, and control. The HC group (2:1 work-to-rest ratio) and LC group (1:1 work-to-rest ratio) underwent training programs comprising 2-4 sets of 8 exercises at an intensity of 80-95% of their maximum heart rate twice a week for 8 weeks. Hematological responses to Bruce's incremental exercise test were measured before and after the intervention. Data were analyzed using a two-way ANOVA with Bonferroni's post hoc test, with a significance level set at P<0.05.
Results: Baseline hematological indices showed no significant differences between pre-diabetic and non-diabetic groups (all, P>0.05). Following the 8-week intervention, there were significant decreases in white blood cells (WBCs) in the LC and LC+BBR groups, and in lymphocytes across all intervention groups except BBR (all, P<0.05). Additionally, hemoglobin and hematocrit levels showed significant reductions in the HC and HC+BBR groups (both, P<0.05). However, in response to Bruce's incremental exercise test, a significant decrease in WBCs was observed in the LC and LC+BBR groups, with reductions of 18% and 25%, respectively (both, P<0.05).
Conclusion: The LC protocol, even without berberine supplementation, seems to provide better immunological benefits and result in less hemolysis compared to the HC protocol, as evidenced by reductions in white blood cell counts.

The presence of atrioventricular accessory pathway can cause heart failure due to the disorder of cardiac depolarization sequence: a case report
Babak Payami, Shirin Azizidoost , Naem Mansouri ,
Volume 81, Issue 10 (January 2024)
Abstract
Background: Wolff-Parkinson-White syndrome is a rare but well-known disease that predisposes a person to cardiac arrhythmias. But sometimes this syndrome is accompanied by heart failure in the affected person. Several causes have been proposed for this complication including recurrent or incessant tachyarrhythmias that are frequently found in symptomatic (especially children) Wolf-Parkinson-White syndrome patients causing heart dysfunction and dilation and dilated cardiomyopathy, and also pre-excitation-related dyssynchrony leading to progressive ventricular remodeling and dilation. In this report, a patient is introduced who has improved his heart failure by radio-frequency ablation of free wall type of this syndrome.
Case Presentation: A 35-year-old man who had a history of Wolff-Parkinson-White syndrome from 8 years ago and suffered from dilatation and reduced left ventricular ejection fraction in recent years was presented with a pre-excited atrial fibrillation attack at the emergency department. The initial surface ECG showed positive delta wave in all precordial leads and negative QRS complexes in interior leads with QRS duration of about 200 ms. He had undergone electrophysiology study and ablation at the left postero-lateral accessory pathway. After ablation of accessory pathway within the months (from November 2022 until June 2023), left ventricular function was gradually improved and the symptoms of the patient's shortness of breath were also decreased.
Conclusion: The existence of heart failure in patients with Wolff-Parkinson-White syndrome can be due to various reasons including the presence of an accessory pathway and the dyssynchrony of intraventricular contraction which is caused by premature excitation of the connected part of the left ventricle by accessory atrioventricular pathway. Although in order to rule out the possibility of the incidental association of the accessory pathway with primary dilated cardiomyopathy and to investigate the segmental dyskinesia, it is necessary to perform diagnostic measures such as echocardiography and cardiac computerized tomography and magnetic resonance imaging, ablation of such accessory pathway not only controls arrhythmic attacks but also leads to the improvement of the left ventricular systolic function even in a middle age patient.

Alireza Dehghan, Mahbube Abshirini, Hamid Nemati, Mahdi Saeedi-Moghadam ,
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.

Volume 81, Issue 11 (February 2024)
Abstract
Background: Most hemiplegic children experience disorders related to lower limbs such as balance. Considering the importance of balance, in order to participate in activities of daily living, it is very important to use modern neuro-rehabilitation methods such as mirror therapy to improve balance. The purpose of the present study was to determine the effectiveness of mirror therapy on the static and dynamic balance of children with hemiplegic CP aged 5 to 12 years.
Methods: This study was conducted as a double-blind, randomized clinical trial on 20 children with spastic hemiplegia aged between 5-12 years old, from June 2021 to August 2022 in Tehran, Iran. Participating children were randomly allocated into test (n=10) and control (n=10) groups. The children in the treatment group underwent 20 treatment sessions during four weeks. Each session consisted of 30 minutes of routine treatment and 15 minutes of mirror therapy for lower limbs. In the control group, sham therapy was performed instead of mirror therapy. The exercises performed in a seated position were: (1) active flexion of hip, knee, and ankle joints, (2) active knee extension plus ankle dorsiflexion, and (3) knee flexion (> 90°). Both groups were measured by the Pediatric Balance Scale to assess static balance and the Timed Up and Go test to assess dynamic balance at entry and the end of the study. SPSS version 26 software was used for statistical analysis.
Results: Examining the results of the evaluations showed that before the treatment, the static and dynamic balance of the two groups did not differ significantly (p> 0/05), but the static and dynamic balance scores of the children in the treatment group after the four weeks mirror therapy period (five days per week) were statistically significant different from the control group (p<0/05).
Conclusion: According to the present study, it seems that mirror therapy as a complementary treatment can have a positive effect on improving balance (static and dynamic) in children with hemiplegic CP.

Volume 81, Issue 11 (February 2024)
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.

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.

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.

Nima Nejati Boushehri , Valiollah Dabidi Roshan ,
Volume 81, Issue 12 (March 2024)
Abstract
Background: Being sedentary due to internet addiction is a common public health problem that causes overweight and obesity. Novel methods are needed for weight control behaviors. This study aimed to determine effects of short-term (two weeks) and moderate-term (four weeks) of virtual reality (VR) exercise program with and without interval Nordic walking (INW) in adolescent boys on novel body composition and maximal oxygen uptake (VO2max) parameters; body adiposity index (BAI), abdominal volume index (AVI), conicity index (CI), waist-to-height ratio (WHtR), and a body shape index (ABSI).
Methods: In a semi-experimental trial during July to December 2023, 70 adolescent boys (age 14.8 years, body mass index (BMI)=24.4 kg/m2 and VO2max 38 ml/kg/min) with the Young IA tests score ranging over five, were selected from the city of Karaj and randomly was classified to VR, INW, VR+INW and control groups. Individual and combined exercise programs of VR and INW were performed (three session in week for 30 min) for two and or four weeks. The parameters were evaluated at the baseline and the follow up phases (two and four weeks after the interventions period) with a repeated measure ANOVA.
Results: According to Young's internet addiction test scores at the beginning of the study, there was no significant difference between the control and intervention groups (P≥0.05). It has been observed that internet addiction negatively affects cardiorespiratory fitness. When a 2-week intervention of VR exercises was implemented along with INW, the improvement in cardiorespiratory fitness (VO2max) was better than when VR exercises alone lasted for four weeks (P≤0.05). After four weeks of INW intervention, separately and in combination with VR, a significant improvement was observed in VO2max, WHtR and BAI values compared to the control group (P≤0.01).
Conclusion: Although improvement in cardiorespiratory fitness of boys with IA can be achieved by doing short and medium term INW, VR and INW+VR exercises, longer interventions, i.e., four weeks or more, cause more significant changes in the novel body composition.

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.

Daryoush Afshari, Mansour Rezaei, Mojtaba Khazaei, Negin Fakhri ,
Volume 81, Issue 12 (March 2024)
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.

Volume 81, Issue 12 (March 2024)
Abstract
Background: The increasing prevalence of non-alcoholic fatty liver disease (NAFLD) in recent years has raised concerns about its significant risks for public health. According to previous studies, a diet with low phytochemicals and high inflammatory index is related to non-alcoholic fatty liver disease. In this study, we intend to investigate the relationship between inflammatory diet and phytochemical diet with NAFLD.
Methods: In this case control study, 112 newly diagnosed patients with NAFLD referred to the Shahid Rahimi Hospital clinic in Khorramabad between January 1400 and April 1401 and 112 healthy individuals without NAFLD and any other chronic diseases as the control group, with the range 23-59 years old were selected. General information, demographics, physical activity level and food intake were collected using general information questionnaire, physical activity questionnaire and valid semi-quantitative food frequency questionnaire (FFQ). The energy received between the people of the two groups was adjusted. People's diet was divided into two anti-inflammatory and pro-inflammatory groups based on the DII index based on the score quartiles.
Results: The results showed a significant relationship between DII score and NAFLD in the crude model (OR: 2.22, 95% CI: 1.04 -4.73), model I (adjusted for energy and age classification) (OR: 2.4, 95% CI:1.07-5.58), model II (adjusted for model I+physical activity, sex, education) (OR:2.77, 95% CI:1.14-6.77) and model III (model II+BMI) (OR: 2.16, 95% CI: 0.81-5.71) and DPI score and NAFLD the crude model (OR: 0.69, 95% CI: 0.32-1.47), model I (adjusted for energy and age classification) (OR: 0.56, 95% CI: 1.29-5.58), model II (adjusted for model I+physical activity, sex, education) (OR:0.58, 95% CI: 0.23-1.44) and model III (model II+BMI) (OR: 0.65, 95% CI: 0.24-1.75).
Conclusion: The results obtained from this study showed an inverse relationship between following an anti-inflammatory diet and the risk of NAFLD. However, there was no correlation between receiving a diet with a high phytochemical index and NAFLD.

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.

Volume 82, Issue 1 (April 2024)
Abstract
Background: Nowadays, understanding healthy treatment strategies is crucial in the post-COVID era where immunocompromised patients are more likely to get exposure to fungal infections. The aim of the research was to investigate studies of fungal infections after COVID-19.
Methods: The systematic review study was conducted from 11 July 2023 to 04 February 2024 in Zahedan, Iran. To extract articles on fungal infections, the vocabulary of selected Medical Subjects Headings (Mesh), other specialized literature was determined and a search strategy was formulated in three databases, Web Science, Scopus, and PubMed, without any time limitation. In addition, the articles were analyzed according to the research objectives, types of fungal infections encountered in immunocompromised patients, their incidence in different immunocompromised patient groups, diagnostic and detection strategies, treatment methods and other background information.
Results: A 15 number of related articles were included. The most common type of study was case report. From the lens of Aspergillus and mucormycosis fungal infections, they were given more attention, and in terms of the type of immunodeficiency, patients with a history of diabetes, including groups of diabetic patients, cancer groups, AIDS patients, and some groups with genetic disorders, were investigated in the studies. Appropriate treatment methods; particularly the use of corticosteroid drugs such as methylprednisolone as intravenous injection, systemic antifungal drugs such as liposomal amphotericin B, Antifungal treatment using high-dose amphotericin B, the use of prophylactic drugs, and isolation of the damaged tissue are recommended as the best treatment strategies. In order to prevent fungal infections in groups of Immunocompromised Patients, it is recommended to use simple hygiene Recommendations.
Conclusion: Analyzing the conditions of cocvid-19 patients and recognizing effective treatment strategies is inevitable, especially in the post- COVID era. A review of the literature showed that prevention and control of fungal infections after covid-19 was critical among immunodeficiency patients and the use of the recommended treatment method for their lifecycle continuity should be more considered by health care providers, health system managers and health policy makers.

Abstract
Background: Prolonged stay in intensive care unit (ICU) can worsen the patient's prognosis and represents a significant economic burden. Previous studies have reported the effectiveness of early mobilization in reducing length of stay in ICUs for adult patients; However, conflicting results have been reported regarding its effects on pediatric patients. Therefore, this research aimed to investigate the impact of early mobilization on the length of stay in the pediatric intensive care unit (PICU) in ventilated children.
Methods: This pilot quasi-experimental study was conducted on 60 children admitted to the Children's Medical Center hospital from March 2020 to June 2021. For the control group, routine care (standard physiotherapy) was started on the second day of intubation and continued until discharge from the intensive care unit. In this study, we used an early mobilization protocol including active and passive exercises. The intervention was implemented by Pediatric intensive care unit nurses under supervision of a pediatric critical care fellowship physician. In the intervention group, passive exercises were started on the second day of intubation. At each shift, the nurses check the level of sedation and presence of delirium in the patients using the Richmond Agitation-Sedation Scale and the Cornell Assessment of Pediatric Delirium questionnaire. If the results showed that the sedation was not deep and delirium was not present, then active exercises were initiated. If the child did not achieve an adequate score indicating the absence of deep sedation and delirium, the patient remained in the passive exercise phase. The length of stay was recorded based on the patients' records. Descriptive and inferential statistics were used for data analysis using SPSS version 23.
Results:  The results showed that there was no significant difference in the length of stay in the pediatric intensive care unit (PICU) between the control (23.20±6.34 days) and intervention (22.60±6.18 days) groups (P=0.77).
Conclusion: The implementation of early mobilization did not significantly reduce the length of PICU stay for pediatric. The researchers are advised to identify and evaluate evidence-based guidelines for implementing early mobilization in children with different diagnoses.

Abstract


Background: Increasing the prevalence of non-contagious and chronic disorders such as Non-alcoholic fatty liver disease (NAFLD) takes the attention of researchers. NAFLD recognized by abnormal accumulation in the liver tissue. The aim of present study is investigating the association between liver size liver enzymes and degree of fatty liver in patients with NAFLD.
Methods: Based on the inclusion criteria, 100 Patients were selected from those referred to the radiology and ultrasonography clinic in Golestan Hospital, Ahvaz, for fatty liver evaluation. The study was carried out during May 2022 to April 2023. Liver enzymes, including alanine aminotransaminase (ALT) and Aspartate aminotransferase (AST), were measured. Based on the ultrasonography results, patients were divided into four groups: healthy, mild fatty liver, moderate fatty liver, and severe fatty liver. Ultrasonography was carried out by an experienced expert. All demographic information of patients was collected. Data were analyzed by SPSS (V25).
Results: According to ultrasonography results, the mean of span was 148.4 ± 14.7 cm, which was significantly higher in patients with grade II of NAFLD (P<0.001). Further analysis revealed the highest difference between grades I and II (P<0.001). Also, a significant difference between grades II and III and grades III and I were found  (P<0.001). Our data showed a significant relationship between body mass index (BMI) and NAFLD grades (P<0.001). The mean of BMI in grade I was significantly lower than in grades II and III (P<0.05). Our findings demonstrated that the mean of ALT in grade I was significantly lower than in grades II and III (P<0.05). In this line, the highest AST level was seen in grade III (P<0.001).
Conclusion: Our study showed that as NAFLD progresses, the enzymes and size of the liver increase. Based on ultrasound findings, the increasing liver size suggests NAFLD grade II, while the rise in AST and BMI suggests NAFLD grade II -III and progression of cirrhosis.

Abstract
Background: Medical errors are one of the biggest problems of the health system in countries. Identifying the factors responsible for these errors is crucial to designing optimal strategies to reduce such occurrences. The aim of this study was to investigate the type and nature of medical errors.
Methods: In this cross-sectional descriptive study, all documented medical errors that occurred between March 2021 and February 2022 at Firoozgar Educational and Medical Center were thoroughly examined. The data collection involved reviewing records from various departments within the center to ensure a comprehensive analysis of error types. The extracted data were processed and analyzed using SPSS v.22 software, allowing for statistical evaluation and identification of potential patterns or trends in medical errors over the specified period.
Results: A total of 214 cases were reviewed. 45.3% of the recorded medical errors occurred in the morning shift, 20.6% in the evening shift and 34.1% in the night shift. The highest number of medical errors was reported by nurses (40.7%), followed by physicians (16.8%) and paramedics (11.7%). The etiology of most medical errors was systemic errors (63.6%) followed by pharmacological errors (15.4%) and technical errors (13.1%) and the most reported systemic errors were of insufficient supervision. Most of the patients who had medical errors were admitted to the inpatient wards (40.7%) and later to the surgical wards (17.3%) and ICU (12.6%). 62.1% of medical errors did not cause any specific complication and in 33.2% of cases, mild complication, 10.7% moderate complication and 3.3% severe complication occurred for patients. 62.1% of medical errors had no consequences for anyone, and in 36.9% of cases, the consequences of errors were to the patient and 1% of the consequences of errors were to the organization and employees.
Conclusion: Most of the reported medical errors were performed by nurses and were uncomplicated errors. Establishing transparent and accurate self-reporting systems is essential to identify medical errors of all employees.

Abstract
Background: A range of diseases can result in end-stage renal disease (ESRD), characterized by a gradual decline in kidney function and associated with significant morbidity and mortality. Currently, renal transplantation as the most effective treatment for managing ESRD. Tissue engineering presents a considerable opportunity to expand the available supply of donor organs for kidney transplants. The aim of this research was to develop a suitable technique for preparing decellularized kidney scaffolds from human tissues.
Methods: The present study was carried out from April 2019 to August 2019 in Mashhad University of Medical Sciences. In this study, two decellularization protocols were compared using sections of human kidney tissue. Therefore, two human kidneys which collected from Ghaem and Imam Reza hospitals were used. In the first protocol, detergents such as 1% Triton X-100 (1A) and 1% SDS (Sodium Dodecyl Sulfate) (1B) were employed, followed by the application of DNase I. The second protocol utilized 0.5% SDS (2A) and 1% SDS (2B). The effectiveness of these techniques was evaluated using hematoxylin and eosin (H&E) staining, 4',6-diamidino-2-phenylindole (DAPI), DNA quantification, and immunohistochemistry (IHC).
Results:  Based on H&E staining results, comparison of the decellularized and native human kidney tissues showed a successful elimination of cell nuclei and the ameliorate extracellular matrix preservation in triton-treated scaffolds (1A) in comparison with the SDS-treated scaffolds (1B) at all times protocols. Furthermore, DNA quantification illustrated triton X-100 in removing DNA was more effective in eliminating DNA from kidney tissues compared to other protocols in renal tissues. In addition, IHC staining demonstrated that the expression of collagen IV and laminin was preserved throughout the decellularization process with Triton X-100 on day fifth. Also, IHC staining indicated human leukocyte antigen (HLA) was completely eliminated in the cortex-medulla of human scaffolds treated with Triton X-100 within day fifth.
Conclusion: Our results demonstrated that triton X-100 outperformed SDS as a detergent for decellularizing human kidneys. Meanwhile these results indicate suitable method for decellularization of human kidneys to produce functional kidneys.

Abstract
Background: COVID-19 is one of the most recent known human infections that has resulted in a global pandemic, causing high rates of morbidity and mortality worldwide. This study evaluated the clinical and epidemiological characteristics of the waves of the corona epidemic within a university surveillance system in southern Iran.
Methods: This cross-sectional study analyzed data from 24,132 individuals with Covid-19 in the registered waves from the beginning of the Corona epidemic from March 2020 to March 2021 in one of the southern universities of Iran. Information on age, gender, number of infections, severity, hospitalization, recovery rate, dominant strain, and compliance with protocols separately for each wave from 2020 to 2021 was collected from the University's databases. After calculating the cumulative incidence rate, mean and standard deviation and drawing graphs, chi-square, Mann-Whitney and one-way ANOVA were used in SPSS26 at a significance level of 5%.
Results: The cumulative incidence of the disease was 11.36%, with a relative frequency of hospitalization at 11.7% and an average hospital stay of Seven days. The highest percentage of protocol compliance was applied in the initial waves. The highest frequency of infection was in the third wave, where men were more infected than women in all waves except the 4th and 5th waves. High blood pressure was the most common underlying disease in patients and the most lung involvement was observed in the fifth wave. Most of the patients have recovered, and the highest rate of recovery was observed in the sixth wave. Significant associations were found between hospitalization duration, underlying conditions, and clinical symptoms across different waves (P<0.001). Systemic symptoms were the most common, and there was a notable difference in radiological findings between waves (P<0.001).
Conclusion: The findings of this study emphasize the significant impact of underlying diseases and the severity of clinical symptoms on hospitalization outcomes. They also highlight the need for appropriate evidence-based management strategies and consideration of clinical changes and radiological patterns when evaluating diseases in different groups.
