Abstract
Background: Coronary angiography is an elective method to confirm or rule out coronary artery disease and to decide on the treatment plan but it is an invasive method and it has some complications. The most important and common complication was hematoma. It could be the cause of mortality and morbidity. The present study was conducted with the aim of investigating the time of hematoma occurrence after angioplasty and investigating the effect of various factors (for example age, sex, BMI, BP, hematocrit, anticoagulant agent, etc.) on the occurrence of hematoma.
Methods: This was a prospective cohort study from March 2022 to March 2023 in Mazandaran heart center. The study population was patients who underwent angioplasty through the femoral artery. If the ACT is less than 150-180, sheet removal was done by applying pressure with the hand on the proximal puncture site for 15-20 minutes and ensuring sufficient hemostasis. Then, the ultrasound of the puncture site was performed before pulling the sheet/one hour and six hours after pulling the sheet, and after collecting the data, the data were analyzed to study the effect of BMI, BP, sex, hematocrit, hemoglobin, age, time of sheet removal, anticoagulant agent, etc. on prevalence of hematoma and it size.
|
Results: 200 patients were examined, of which 44(22%) had hematoma. Women had hematoma more than men (P<0.05). BMI and blood pressure in patients with hematoma decreased and increased, respectively (P<0.05). Older age, female gender, lower hematocrit, and longer duration of sheet retention were effective factors in increasing hematoma size (P<0.05). In the logistic regression model, with increasing BMI, the chance of hematoma occurrence decreased (P=0.029, OR=0.831).
Conclusion: Controlling blood pressure and preventing of decreasing the hematocrit, reduces the incidence of hematoma in patients after angiography. Also, preventing hematocrit drop and removal of sheet at the appropriate time, can prevent of increasing in size of hematoma. There is some difference between nursing report and sonography finding. Nursing report overestimated the hematoma size.

Abstract
Background: Asthma is a chronic inflammatory disease of the airways. Various tests and questionnaires are designed to monitor the severity of asthma and help the therapist and the health system prescribe the best treatment to control it. This study was designed to compare two methods Asthma Control Questionnaires (ACQ) and Asthma Control test-child (ACT-CHILD) in children with asthma.
Methods: This descriptive cross-sectional study was conducted on 92 children with asthma referred to the Taleghani hospital, Gorgan, in 2022-2023. Patients were in a range of age 4-16 years. Asthma control was evaluated and compared by two methods ACT-CHILD and ACQ. ACT-CHILD included one version for 4-11-year patients completed by their parents and another one for 12-16 –year patients completed by the patients. The clinical symptoms, age, gender and the parents' records related to asthma were completed during the clinical interview. Data was analyzed using Chi-square and Spearman correlation tests. The degree of agreement between two questionnaires was determined using the Kappa coefficient.
|
Results: 84 children aged 4-11 years (91.3%) and 8 children aged 12-16 years (8.7%) were included in the study. According to the ACT-CHILD, 40.2% of children (n=37) had controlled asthma, 44.6% (n=41) had partially controlled asthma, and 15.2% (n=14) had uncontrolled asthma. Based on the ACQ, controlled asthma was observed in 18.5% (n=17), partially controlled asthma in 35.8% (n=33), and uncontrolled asthma in 45.7% (n=42) of children. Asthma control results based on two questionnaires were significantly different from each other (P<0.001). The agreement between the ACT-CHILD and ACQ methods in evaluating children's asthma was at a weak level (P=0.014, κ=0.157), however, a significant negative correlation was observed between the scores of the ACT-CHILD and ACQ questionnaires (r=-0.588, P>0.001) which after categorizing based on age group, this correlation was confirmed only in children aged 4-11 years (r=-0.627, P>0.001).
Conclusion: Our findings showed that there is a poor agreement between ACT-CHILD and ACQ results in the assessment of asthma control. Further studies are recommended.

Abstract

Left ventricular thrombosis (LVT) is a very serious condition and life-threatening complication that usually occurs after acute occlusion of the left anterior descending (LAD) coronary artery followed by acute myocardial infarction with ST-segment elevation (STEMI), which leads to significant regional wall motion abnormality (RWMA). It should be noted that its diagnosis, treatment, and management are challenging now and depend on various factors such as the type of thrombus, time of percutaneous coronary intervention (PCI), and underlying disease. The preferred diagnostic method is cardiovascular magnetic resonance imaging (CMR), but transthoracic echocardiography (TTE) is routinely used for diagnostic and screening purposes also follow-up of response to treatment. It is worth mentioning that when the diagnosis of left ventricular thrombus is not clear with conventional echocardiography, contrast echocardiography is used for more resolution and detailed information. Left ventricular thrombosis can appear in both acute and chronic forms and lead to significant complications, the most important of them are stroke and systemic arterial embolism (SE). According to previous studies, vitamin K antagonist (warfarin) by keeping INR within the therapeutic range currently used to treat left ventricular thrombosis. Although the use of direct oral anticoagulants (DOAC) has brought excellent outcomes, but due to the lack of large clinical trials, the routine use of these agents is controversial, and only in case of warfarin intolerance or contraindications, DOACs can be used as an alternative. Generally, the best way to prevent left ventricular thrombosis is primary percutaneous coronary angioplasty (primary PCI) which preserves left ventricular function. Depending on the sensitivity of the diagnostic method, thrombus will likely resolve in >50% of patients by six months after the MI. On the other hand, in rare cases, surgery is indicated if a thrombosis remains despite the medical treatment especially if it is accompanied by a left ventricular aneurysm. The purpose of this narrative review is to evaluate the latest evidence in the field of left ventricular thrombosis management and to adopt the best approach for these patients.

Abstract
Background: Systemic Sclerosis (SSc) is an autoimmune disease with multi-organ involvement mostly due to fibrosis and ectopic or excessive collagen fibers production in organs. Myocardial fibrosis is the main finding of cardiac involvement in patients with systemic sclerosis. In recent studies, the presence of Fragmented QRS complexes (FQRS) has been shown in the surface electrocardiogram in relation to fibrosis.
Methods: The present study is a case-control study during March 2019 to February 2020 that was conducted in 148 patients with scleroderma referred to the Rheumatology clinic in Shariati Hospital and 101 non-ischemic individuals in the control group matched by age and sex with the patient group. All the medical records were reviewed and those who were low risk according to 10-year atherosclerotic cardiovascular disease (ASCVD) risk assessment were selected as case groups. Data of ECG were evaluated for availability of FQRS or conductive abnormalities and calculating PR, QRS, QT, QTc and Tp-e intervals.
Results: Of the 141 patients with systemic sclerosis, 127(85.81%) were female and 21(14.19%) were male. In the control group, 81 women (80.2%) were present. 61(41.2%) of patients with scleroderma and 8(7.9%) of the control group in this study had FQRS changes in their electrocardiogram. In this study, QRS, QTc and Tp-e intervals were significantly higher in patients with systemic sclerosis compared to those in the control group. The frequency of FQRS, LAHB and LPHB in patients with systemic sclerosis was significantly more than control group. The relationship between PR, QRS, QTc, Tp-e intervals with age, length of disease onset and the severity of skin involvement was assessed. There was a significant correlation between PR-interval and age. Furthermore, there were a correlation between QRS interval and Rodnan skin score, Pulmonary Artery Pressure and Finger to Palm. It is also a meaningful correlation between QTc interval and Rodnan score.
Conclusion: The FQRS finding in electrocardiogram in patients with systemic sclerosis, which has no obvious cardiac symptoms, may indicate myocardial fibrosis and predict future cardiac disorders. |

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.

Abstract
Background: Identifying the epidemiological aspects of central nervous system (CNS) tumors is the first step in implementing management protocols to control the condition of these tumors. We aimed to examine the epidemiology and histopathology of both benign and malignant tumors of the CNS in one of the referral and university centers in the east of Iran.
|
Methods: This cross-sectional study was conducted on all files of patients admitted to Qaem Hospital in Mashhad City, Iran, in a period of 10 years from March 2009 to February 2018 with a definitive diagnosis of benign or malignant tumors of the CNS, including tumors of the brain, cerebellum, spinal cord, or meningeal membranes. Information sources included the patients' physical files and the hospital information system (HIS). The statistical software SPSS version 28.0 for Windows (IBM SPSS, Armonk, New York, USA) was used for the statistical analysis.
Results: In total, 775 patients with benign and 771 patients with malignant CNS tumors were included in the study. Regarding epidemiological aspects of benign tumors, the incidence rate of women was almost twice that of men (68.47% versus 31.53%), with an overall average age of 45.31±19.81 years. The most common benign tumors were meningioma (72.77%), followed by schwannoma (13.67%). Regarding malignant brain tumors, the mean age of affected patients was 36.64±19.67 years, with males accounting for 53.04% of cases and females for 46.96%. The most frequent type of tumor was glioblastoma (32.68%), followed by diffuse astrocytoma (16.47%). Both benign and malignant CNS tumors were associated with significant hospital mortality; in-hospital mortality rates for benign and malignant tumors were 10.1% and 17.5%, respectively. Tumor type and its grade were the main determinants of early death in malignant CNS tumors.
Conclusion: The epidemiological characteristics of benign and malignant tumors in our study community were similar to the reports presented in other communities. Knowledge of these characteristics provides the possibility of managing patients and reducing morbidity and mortality related to these tumors.

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.

Abstract
Background: Identifying factors that influence the length of hospital stay for suspected stroke patients is crucial for optimizing the utilization of hospital resources. This study aimed to determine the factors associated with the length of hospital stay for suspected stroke patients transferred to Qaem Hospital in Mashhad through emergency services using survival analysis.
Methods: In this historical cohort study, general information was gathered for all suspected stroke patients who sought emergency services in Mashhad, the largest city in northeast Iran, from March 21, 2018, to March 20, 2019, and were then transferred to the Emergency Department of Qaem Hospital. Pre-hospital emergency data were integrated with hospital records using the mission ID. The primary outcome assessed in the study was the length of hospital stay, with model implementation carried out using the statistical software Stata.
|
Results: The median hospitalization time until patients' recovery was seven days. Out of the 578 participants, 386 cases (66.8%) recovered, while the remaining 190 cases (33.2%) were censored (83 individuals had died during the study, and 107 individuals had exited the hospital for other reasons). The average age of patients at the time of hospitalization was 71.13±13.01 years. Statistical analysis employing Log-rank and Breslow tests identified a significant difference in hospitalization duration among patients receiving various levels of care and based on their insurance status. During multivariate analysis, the Cox regression model was considered unsuitable due to some variables not meeting the proportional hazards assumption, leading to the utilization of AFT models. Following the evaluation of AFT models, including Log-normal, Log-logistic, Exponential, and Weibull, the log-normal model emerged as the most suitable choice, exhibiting AIC and BIC values of 1273.909 and 1356.740, respectively. Significant variables influencing length of stay included patient admission priority, insurance status, season, and residency status.
Conclusion: The study suggests that parametric survival models are effective for analyzing lifetime data. Additionally, in light of the significant variables identified, enhancing facility readiness and resource allocation could facilitate more efficient planning and implementation.
