Abstract
PURPOSE This study aimed to implement the Quality of Care (QoC) Assessment Tool from the National Spinal Cord/Column Injury Registry of Iran (NSCIR-IR) to map the current state of in-hospital QoC of individuals with Traumatic Spinal Column and Cord Injuries (TSCCI). METHODS The QoC Assessment Tool, developed from a scoping review of the literature, was implemented in NSCIR-IR. We collected the required data from two primary sources. Questions regarding health system structures and care processes were completed by the registrar nurse reviewing the hospital records. Questions regarding patient outcomes were gathered through patient interviews. RESULTS We registered 2812 patients with TSCCI over six years from eight referral hospitals in NSCIR-IR. The median length of stay in the general hospital and intensive care unit was four and five days, respectively. During hospitalization 4.2% of patients developed pressure ulcers, 83.5% of patients reported satisfactory pain control and none had symptomatic urinary tract infections. 100%, 80%, and 90% of SCI registration centers had 24/7 access to CT scans, MRI scans, and operating rooms, respectively. Only 18.8% of patients who needed surgery underwent a surgical operation in the first 24 h after admission. In-hospital mortality rate for patients with SCI was 19.3%. CONCLUSION Our study showed that the current in-hospital care of our patients with TSCCI is acceptable in terms of pain control, structure and length of stay and poor regarding in-hospital mortality rate and timeliness. We must continue to work on lowering rates of pressure sores, as well as delays in decompression surgery and fatalities.

Abstract
BACKGROUND Since its introduction, thoracic endovascular aortic repair (TEVAR) has revolutionized the treatment of type B aortic dissections (TBADs). However, the proximal aspect of the aortic pathology treated may infringe on the origin of the left subclavian artery or even more proximally. Hence, to ensure durable outcomes, the origin of these vessels needs to be covered, but an extra-anatomical bypass is required to perfuse vital branches, known as aortic arch debranching. This series aims to describe and delineate the disparities of aortic arch debranching during TEVAR for TBAD. METHODS A retrospective review and analysis of a multicenter international database was conducted to identify patients with TBAD treated with TEVAR between 2005 and 2021. Data analyzed included patient demographics, disease characteristics, operative characteristics, and postoperative outcomes with follow-up on mortality and reintervention. All statistical analyses were carried out using IBM SPSS 26. Patient survival was calculated using a Kaplan-Meier survival analysis, and a P value of less than 0.05 was considered statistically significant. RESULTS A total of 58 patients were included in the analysis, of which 27 (46.6%) presented with complicated disease and 31 were uncomplicated, of which 10 (17.2%) were classed as high risk and 21 (36.2%) low risk. Zone 2 was the most common proximal landing zone for the stent graft. Left subclavian artery bypass was performed selectively (26%), with 1 stroke occurring, likely due to embolic reasons. A further 6 underwent more proximal aortic debranching before TEVAR (10%) and was a significant risk factor for mortality and the number of stents deployed. The overall rates of reintervention and mortality were 17.2% (n = 10) and 29.3% (n = 17). CONCLUSIONS Aortic arch debranching and TEVAR for TBAD is associated with significant mortality. Future developments to treat aortic arch pathology could incorporate branched graft devices, eliminating the need for debranching, improving stroke rates, and reducing future reinterventions.

Abstract
Purpose.This study aims to predict radiotherapy-induced rectal and bladder toxicity using computed tomography (CT) and magnetic resonance imaging (MRI) radiomics features in combination with clinical and dosimetric features in rectal cancer patients.Methods.A total of sixty-three patients with locally advanced rectal cancer who underwent three-dimensional conformal radiation therapy (3D-CRT) were included in this study. Radiomics features were extracted from the rectum and bladder walls in pretreatment CT and MR-T2W-weighted images. Feature selection was performed using various methods, including Least Absolute Shrinkage and Selection Operator (Lasso), Minimum Redundancy Maximum Relevance (MRMR), Chi-square (Chi2), Analysis of Variance (ANOVA), Recursive Feature Elimination (RFE), and SelectPercentile. Predictive modeling was carried out using machine learning algorithms, such as K-nearest neighbor (KNN), Support Vector Machine (SVM), Logistic Regression (LR), Decision Tree (DT), Random Forest (RF), Naive Bayes (NB), Gradient Boosting (XGB), and Linear Discriminant Analysis (LDA). The impact of the Laplacian of Gaussian (LoG) filter was investigated with sigma values ranging from 0.5 to 2. Model performance was evaluated in terms of the area under the receiver operating characteristic curve (AUC), accuracy, precision, sensitivity, and specificity.Results.A total of 479 radiomics features were extracted, and 59 features were selected. The pre-MRI T2W model exhibited the highest predictive performance with an AUC: 91.0/96.57%, accuracy: 90.38/96.92%, precision: 90.0/97.14%, sensitivity: 93.33/96.50%, and specificity: 88.09/97.14%. These results were achieved with both original image and LoG filter (sigma = 0.5-1.5) based on LDA/DT-RF classifiers for proctitis and cystitis, respectively. Furthermore, for the CT data, AUC: 90.71/96.0%, accuracy: 90.0/96.92%, precision: 88.14/97.14%, sensitivity: 93.0/96.0%, and specificity: 88.09/97.14% were acquired. The highest values were achieved using XGB/DT-XGB classifiers for proctitis and cystitis with LoG filter (sigma = 2)/LoG filter (sigma = 0.5-2), respectively. MRMR/RFE-Chi2 feature selection methods demonstrated the best performance for proctitis and cystitis in the pre-MRI T2W model. MRMR/MRMR-Lasso yielded the highest model performance for CT.Conclusion.Radiomics features extracted from pretreatment CT and MR images can effectively predict radiation-induced proctitis and cystitis. The study found that LDA, DT, RF, and XGB classifiers, combined with MRMR, RFE, Chi2, and Lasso feature selection algorithms, along with the LoG filter, offer strong predictive performance. With the inclusion of a larger training dataset, these models can be valuable tools for personalized radiotherapy decision-making.

Abstract
OBJECTIVES Chronic venous disease (CVD) of the lower extremities is one of the common venous diseases in different populations, with a wide range of clinical manifestations and undetermined exact prevalence owing to different population characteristics and measurement methods. This study aimed to estimate the prevalence of CVD among the modern Iranian urban population and determine its associated risk factors. METHODS The Heart Assessment and Monitoring in Rajaie Hospital study, a longitudinal population-based cohort, aims to investigate the baseline prevalence and the 10-year incidence of cardiovascular diseases and associated risk factors in the adult population aged 30 to 75 years with no overt cardiovascular diseases in Tehran. Two instructed interventional cardiologists performed CVD evaluation using the Clinical-Etiology-Anatomy-Pathophysiology classification. CVD was graded as C1 to C6, and chronic venous insufficiency (CVI) as C3 to C6. A multivariable regression model was used to analyze the association between CVD and prespecified covariates of age, sex, body mass index (≥30 kg/m2), smoking, hypertension, diabetes mellitus, physical activity, dyslipidemia, and delivery method. RESULTS CVD prevalence among 1176 participants was 36.5% (95% confidence interval [CI], 33.8-39.3) and was higher in women than men (44.2% vs 23.5%). CVI prevalence was only 0.7% (95% CI, 0.3-1.3). Multivariable analysis showed that advanced age (odds ratio [OR], 1.06; 95% CI, 1.04-1.08), female sex (OR, 2.98; 95% CI, 2.14-4.14), and body mass index of ≥30 (OR, 1.36; 95% CI, 1.03-1.81) were independently associated with CVD. Physical activity (OR, 0.77; 95% CI, 0.58-1.02) was nearly protective, whereas other factors, including traditional cardiovascular risk factors, had no meaningful association with CVD. CONCLUSIONS Our findings showed that CVD was prevalent in the modern Iranian urban population. However, considering the very low prevalence of the higher stages of the disease, the benefit of mass screening is debatable, and better risk discriminators should be investigated.

Abstract
BACKGROUND There has been a revolution in the management of type B aortic dissection (TBAD) over the last 2 decades due to the increasing development of endovascular techniques, with the prime example being thoracic endovascular aortic repair (TEVAR). However, many controversies concerning the use of TEVAR in TBAD exist. For instance, there is little available evidence suggesting any differences in demographics, disease characteristics, intervention technicalities, and clinical outcomes between males and females as well as different ethnicities when undergoing TEVAR for TBAD, both in the short and long term. Also, there is no risk prediction model/tool available. The objective of this international study is to describe and delineate the disparities between male and female patients of different ethnicities in terms of demographics, disease and interventional characteristics, and clinical outcomes. METHODS Over 17 years a total of 58 TBAD patients were admitted to 2 tertiary vascular centres and treated using TEVAR. Mortality, postoperative complications and reintervention data were recorded for the first 30 days after the procedure as well as during follow-up. Follow-up for all patients lasted until the study endpoint or until a patient's death. Data were analysed retrospectively using IBM SPSS statistical package 26 for Windows. RESULTS The mean age was similar between the 2 groups, with the majority of patients in both being Caucasian. More than half of the males had complicated TBAD, while the majority of females were classed as having uncomplicated disease. The most commonly utilized proximal and distal landing zone for the TEVAR stent graft was zone 2 and zone 4, respectively. The mean proximal stent diameter was significantly larger in males compared to females (P = 0.004). The difference in mean distal diameter between the 2 groups was insignificant (P = 0.721). The mean total stent coverage of the thoracic aorta was 251.3 mm in male patients compared to 291.2 mm in females (P = 0.203). A total of 32 patients underwent adjunctive procedures. Seven (17%) of the males had one or more postoperative complications compared to 2 (12%) females. Nine (22%) males underwent a reintervention procedure post TEVAR compared to only 1 (6%) female (P = 0.136). Overall, males had a mortality rate of 24% (n = 10) compared to 41% of females (n = 7) (P = 0.201). Estimated survival of males and females post TEVAR was 80.4 ± 9.6 months and 69.7 ± 14.4 months (P = 0.428). For the total population, the number of stent grafts was inversely correlated with mortality. CONCLUSIONS Despite the favourable clinical outcomes achieved by TEVAR in TBAD, there remains a grey area concerning its management. Thus, it is important to perform risk stratification of individual patients using their demographics and comorbidities, particularly scrutinizing patient sex and ethnic origin, when considering intervention for TBAD to achieve optimum results.

Abstract
Massive device-to-device communication nodes and Internet of Things (IoT) devices are expected to be crucial components in next-generation wireless networks. However, the energy constraint of these nodes presents a challenge since the energy of the batteries is limited. Motivated by this, radio frequency energy harvesting (EH) has been developed as an efficient strategy to overcome the energy constraint of IoT devices and sensor networks. In this paper, a wireless-powered dual-hop amplify-and-forward relaying system, in the absence of a direct link between the source (S) and the destination (D), is considered. It is assumed that a dedicated power beacon (PB) transmits an energy-bearing signal from which the power-constrained S and relay (R) harvest energy. Theoretical derivations of bit error probability, outage probability, and throughput expressions are performed for both linear and non-linear energy harvesting models. Moreover, the theoretical results provided for different system parameters are validated via Monte Carlo simulations. The obtained results reveal the difference between the realistic non-linear EH model and the conventional linear EH model, which overestimates the system performance at high levels of harvested energy. Thus, it leads to misunderstanding the real performance of the EH systems. However, at low levels of harvested energy, both models behave similarly and provide realistic results.

Abstract
OBJECTIVES This study sought to compare the safety and efficacy of the balloon-expandable stent (BES) and the self-expandable stent (SES) in the endovascular treatment of coarctation of aorta. BACKGROUND Coarctoplasty with stents has conferred promising results. Although several nonrandomized studies have approved the safety and efficacy of the BES and the SES, no high-quality evidence exists for this comparison. METHODS In the present open-label, parallel-group, blinded endpoint randomized pilot clinical trial, adult patients with de novo native aortic coarctation were randomized into Cheatham-platinum BES and uncovered nitinol SES groups. The primary outcome of the study was a composite of procedural and vascular complications. The secondary outcomes of the study consisted of the incidence of aortic recoarctation, thoracic aortic aneurysm/pseudoaneurysm formation, and residual hypertension at a 12-month follow-up. RESULTS Among 105 patients who were screened between January 2017 and December 2019, 92 eligible patients (32 women [34.8%]) with a median age of 30 years (IQR: 20-36 years) were randomized equally into the BES and SES groups. The composite of procedural and vascular complications occurred in 10.9% of the BES group and 2.2% of the SES group (odds ratio: 0.18; 95% CI: 0.02-1.62; P = 0.20). Aortic recoarctation occurred in 5 patients (5.4%), 3 patients (6.5%) in the BES group and 2 patients (4.3%) in the SES group (odds ratio: 0.65; 95% CI: 0.10-4.09; P = 0.64). Only 1 patient (1.1%) was complicated by aortic pseudoaneurysm. Hypertension control was achieved in 50% of the study population, with an equal distribution in the 2 study groups at the 12-month follow-up. CONCLUSIONS Both the BES and the SES were safe and effective in the treatment of native coarctation.

Abstract
INTRODUCTION AND OBJECTIVES Long-term follow up of patients with hyper IgE syndrome (HIES), as a primary immunodeficiency disorder, has been poorly investigated. This study describes common clinical and immunological features of patients with HIES in the last 10 years in Shiraz University of Medical Sciences, Shiraz, Iran. METHODS AND PATIENTS In this cross-sectional study, the symptoms and medical records of 18 patients, who were diagnosed with HIES, were observed. Genetic and immunologic study was also performed. RESULTS Eighteen patients with the mean age of 13 years old were investigated. Ten patients were detected to have mutations in DOCK8 gene and autosomal recessive HIES (AR-HIES); and four patients were found with STAT3 mutation and autosomal dominant HIES (AD-HIES). So, 14 patients with known genetic results were considered for further data analysis. Food allergy, eczema, viral and skin infections were the major complications of AR-HIES patients. The major clinical complications of AD-HIES patients were pneumonia, skin infections and eczema. Food allergy and viral infection were significantly higher in DOCK8 deficient patients. The most common causes of hospitalization in both AR-HIES and AD-HIES patients were pneumonia, skin infections and sepsis. The most common cause of death was found to be sepsis. CONCLUSIONS AD-HIES and AR-HIES cannot be differentiated only based on the clinical presentations. Genetic features are also necessary for better diagnosis. This study, summarizing the clinical, immunological and genetic information of the patients with AD-HIES and AR-HIES, may open a way for better diagnosis and management of HIES.

Abstract
Hedgehogs are small spiny-coated insectivores. Due to their low body weight, calm character, and easy maintenance, they are kept as pets. It is therefore worthwhile to care about hedgehogs' health problems and to provide pet owners with information about their reproduction. Moreover, it is necessary to be familiar with their anatomy so as to satisfy the need to improve nutrition and medical care, even surgery. This study was carried out on five adult male European hedgehogs euthanased in a chloroform chamber. The European hedgehog's oval testes are invisible in inguinal region because they have no true scrotal sac. The testes are located in the craniocaudal direction with dorsolateral epididymal attachments. The vesicular glands, the European hedgehog's largest accessory sex glands, are lobulated structures containing dorsomedial and ventrolateral parts on each side. The prostate is an oval gland with right and left lobes. The paired bulbourethral glands are laid on the ischiocavernosus muscle. Histologically the vesicular, prostate gland ducts and ductus deferens as well as urethra separately were discharged in a diverticlum at the level of the pelvic urethra end. A sigmoid flexure exists in the proximal part of shaft body of the penis. There are two retractor penile muscles. In dorsal end of the penile glans, there is a small urethral process with two nail- -like, needle-shaped structures. They are on both sides of the urethral process. Furthermore, there are two intromittent sacs (Sacculus urethralis) in the ventral part of the end of the penis. (Folia Morphol 2018; 77, 1: 36-43).

Abstract
This article reports on the synthesis and full characterization of innovative silica-based nanoparticle composed of fumed silica as a core decorated with polyethylenimine (PEI) with different molecular weights (25, 10 and 1.8 kDa). Wide range of analytical, spectroscopic, and microscopic methods (TEM, DLS, ζ potential, elemental analysis (EA), TNBS and FTIR) were used to characterize the nanoparticles. Furthermore, transfection efficiency of these nanoparticles as non-viral vector was examined. The silica-PEI conjugates retained both the ability of PEI to fully condense plasmid DNA at low N/P ratios and suitable buffering capacity at the endosomal pH range. PEI-functionalized silica remarkably enhanced EGFP-N1 gene expression in murine neuroblastoma (Neuro-2A) cells up to 38 folds compared to PEI 25 kDa. Meanwhile the results of the cytotoxicity assays indicated that these silica-PEI conjugates have acceptable level of viability.

Abstract
Neuroendocrine tumors (NET) arise from neuroendocrine cells and are an exceedingly rare malignancy in the gallbladder. In this case report, a 52-year-old woman with complaints of episodic abdominal pain for two months prior was admitted to our hospital. She had no other signs and symptoms and her laboratory tests were within normal limits. Ultrasonography showed a broad-necked mass (26 × 12 mm) in the gallbladder for which she underwent laparoscopic cholecystectomy. The final pathological diagnosis was a high grade neuroendocrine carcinoma of the gallbladder with involvement of the lymph nodes and omentum. The patient received the chemotherapy regimens of gemcitabine plus cisplatin, followed by docetaxel plus sunitinib for her metastatic liver lesions. She also underwent radiofrequency ablation. Serial CT-scans revealed metastatic liver lesions that had decreased in size, with no significant improvement. The patient refused additional treatment and at 46 months, she was doing well with no complaints of any pain, disease recurrence, or metastatic progression.

Abstract
Evidence indicates that optimal nutrition plays a role in bone formation and maintenance. Besides major components of mineralization such as calcium, phosphorus, and vitamin D, other nutrients like boron and fluoride have beneficial role, too. In this study, 34 male Wistar rats were divided into five groups: control diet, fluoride, fluoride + boron, fluoride + calcium + vitamin D, and flouride + boron + calcium + vitamin D. Boron equal to 1.23 mg, calcium and vitamin D equal to 210 mg + 55 IU and fluoride equal to 0.7 mg/rat/day was added to their drinking water for 8 weeks. Plasma blood samples and bones were collected. Findings are evidence that fluoride + boron intake revealed significant positive effects on bone mechanical properties and bone metabolic hormones. These findings suggest that combined intake of these two elements has beneficial effects on bone stiffness and breaking strength comparing to even calcium + vitamin D supplementation. This evidence dealing with health problems related to bone and skeletal system in humans should justify further investigation of the role of boron and fluoride with other elements in relation to bone.

Abstract
Objectives: Reliable evidence is the keystone for any noncommunicable disease (NCD) prevention plan to be initiated. In this study we carried out a risk factor investigation based on the WHO Stepwise approach to Surveillance (STEPS). Methods: The study was conducted on 1000 adults between 15 and 64 years of age living in Ardabil province, north-west Iran during 2006, based on the WHO STEPS approach to surveillance of risk factors for NCD. At this stage only the first and second steps were carried out. Data were collected through standard questionnaires and methods analyzed using STATA version 8 statistical software package. Results: 29.0% of men and 2.6% of women were current daily tobacco smokers. The mean number of manufactured cigarettes smoked per day was 18.9 among current daily smokers. Smoking was most prevalent among men of low-income families and those of lower education. The mean body mass index (BMI) was 26.6 kg/m2, and was significantly correlated with systolic blood pressure. 58.9% were overweight or obese; 18.0% had raised blood pressure and 3.7% had isolated systolic hypertension. The mean number of servings of fruit consumed per day was 1.1; 33.1% had low levels of activity. Combined risk factor analysis showed that 4.1% of participants were in the low-risk group (up to 5.1% among men and 3.2% among women). Those in the high-risk group comprised 25.6% in the 25- to 44-year age group and 49.7% in the 45- to 64-year age group. Mean BMI increased by age in both sexes at least at the first three decades of adult life. Conclusion: Based on observed status of risk for cardiovascular health, burden of cardiovascular diseases is expected to increase if an effective prevention strategy is not undertaken.

The radiotracer technetium-99m methoxyisobutyl isonitrile ((99m)Tc-MIBI) has been widely used for myocardial blood flow imaging. We investigated the genotoxicity of (99m)Tc-MIBI in cultured human lymphocytes at the same concentration used in patients. Radioactivity doses were determined in whole blood at 5 min post-injection of 20 mCi (99m)Tc-MIBI in patients. Subsequently, whole blood of human volunteers was incubated with 1, 2.3, 4 or 8 microCi (99m)Tc-MIBI. After a 30-min incubation, the lymphocytes were stimulated with a mitogen to assay for micronuclei in cytokinesis-blocked binucleated cells. The frequency of micronuclei in samples treated with this radiopharmaceutical up to 2-fold (8 microCi) the concentration of (99m)Tc-MIBI normally found in the blood of patients was not more than in control lymphocyte cultures. We concluded that there is no increased induction of micronuclei in lymphocytes incubated with (99m)Tc-MIBI at the radioactivity doses used for diagnostic purposes.

Abstract
INTRODUCTION Cardiac syndrome X (CSX) includes chest pain, positive exercise stress test and/or radionuclide test for ischaemia and normal coronary angiography. There is no obvious aetiology for this syndrome. Some mechanisms such as endothelial dysfunction and oestrogen deficiency have been invoked. In this study, we surveyed the association of Helicobacter pylori (HP) infection with cardiac syndrome X. METHODS HP infection was detected by urea breath test (UBT) in patients with cardiac syndrome X, and compared with a sex- and age-matched control group. Patients with dyspepsia and coronary spasm were excluded. Statistical analysis was carried out using chi-square test. RESULTS 40 patients (29 females and 11 males) with cardiac syndrome X aged between 30 and 65 years (mean 45.51 +/- 5.03 years) were compared with a control group (28 females and 12 males) aged between 31 and 64 years old (mean 44.93 +/- 5.16 years). 95 percent of patients were HP infected, while only 47.5 percent of members of the control group were infected (p-value is less than 0.001). CONCLUSION Considering the high prevalence of HP infection in patients with CSX in our sample and probable causative effect of chronic infection in vascular diseases, we believe that there is a probable role for HP infection in the pathogenesis of CSX.
