Abstract
BACKGROUND To investigate the genetics of early-onset progressive cerebellar ataxia in Iran, we conducted a study at the Children's Medical Center (CMC), the primary referral center for pediatric disorders in the country, over a three-year period from 2019 to 2022. In this report, we provide the initial findings from the national registry. METHODS We selected all early-onset patients with an autosomal recessive mode of inheritance to assess their phenotype, paraclinical tests, and genotypes. The clinical data encompassed clinical features, the Scale for the Assessment and Rating of Ataxia (SARA) scores, Magnetic Resonance Imaging (MRI) results, Electrodiagnostic exams (EDX), and biomarker features. Our genetic investigations included single-gene testing, Whole Exome Sequencing (WES), and Whole Genome Sequencing (WGS). RESULTS Our study enrolled 162 patients from various geographic regions of our country. Among our subpopulations, we identified known and novel pathogenic variants in 42 genes in 97 families. The overall genetic diagnostic rate was 59.9%. Notably, we observed PLA2G6, ATM, SACS, and SCA variants in 19, 14, 12, and 10 families, respectively. Remarkably, more than 59% of the cases were attributed to pathogenic variants in these genes. CONCLUSIONS Iran, being at the crossroad of the Middle East, exhibits a highly diverse genetic etiology for autosomal recessive hereditary ataxia. In light of this heterogeneity, the development of preventive strategies and targeted molecular therapeutics becomes crucial. A national guideline for the diagnosis and management of patients with these conditions could significantly aid in advancing healthcare approaches and improving patient outcomes.

Abstract
OBJECTIVE Mitochondrial leukodystrophies (MLs) are mainly caused by impairments of the mitochondrial respiratory chains. This study reports the mutation and phenotypic spectrum of a cohort of 41 pediatric patients from 39 distinct families with MLs among 320 patients with a molecular diagnosis of leukodystrophies. METHODS This study summarizes the clinical, imaging, and molecular data of these patients for five years. RESULTS The three most common symptoms were neurologic regression (58.5%), pyramidal signs (58.5%), and extrapyramidal signs (43.9%). Because nuclear DNA mutations are responsible for a high percentage of pediatric MLs, whole exome sequencing was performed on all patients. In total, 39 homozygous variants were detected. Additionally, two previously reported mtDNA variants were identified with different levels of heteroplasmy in two patients. Among 41 mutant alleles, 33 (80.4%) were missense, 4 (9.8%) were frameshift (including 3 deletions and one duplication), and 4 (9.8%) were splicing mutations. Oxidative phosphorylation in 27 cases (65.8%) and mtDNA maintenance pathways in 8 patients (19.5%) were the most commonly affected mitochondrial pathways. In total, 5 novel variants in PDSS1, NDUFB9, FXBL4, SURF1, and NDUSF1 were also detected. In silico analyses showed how each novel variant may contribute to ML pathogenesis. CONCLUSIONS The findings of this study suggest whole-exome sequencing as a strong diagnostic genetic tool to identify the causative variants in pediatric MLs. In comparison between oxidative phosphorylation (OXPHOS) and mtDNA maintenance groups, brain stem and periaqueductal gray matter (PAGM) involvement were more commonly seen in OXPHOS group (P value of 0.002 and 0.009, respectively), and thinning of corpus callosum was observed more frequently in mtDNA maintenance group (P value of 0.042).

Abstract
BACKGROUND Pediatric migraine prophylaxis is indicated when headaches are frequent and/or disabling. We aimed to conduct a study to compare the efficacy of cinnarizine and amitriptyline in pediatric migraine prophylaxis. METHODS In a randomized, double-blind trial, patients aged 4-17 years with migraine who were eligible for prophylaxis enrolled. The primary outcome was a reduction response rate of ≥50% with p < 0.005 with respect to headache characteristics. The secondary outcome was migraine disability assessment. We evaluated patients every four weeks for three months: T1: week 4, T2: week 8 and T3: week 12. The safety profile was also assessed. RESULTS Thirty patients were randomly assigned to each group. However, 43 patients completed the trial. Headache frequency decreased in amitriptyline group more effectively in T1 (p = 0.004). Amitriptyline was more successful in reducing the headache duration in all three periods (p < 0.005). There was no significant difference in severity improvement and reducing disability score between the two groups (p > 0.005). No serious adverse events were observed. CONCLUSIONS Both medications are effective in ameliorating migraine headaches and related disabilities. However, amitriptyline appears be a preferable option over cinnarizine, given its faster onset of action, efficacy in reducing headache duration and longer-lasting effects.Trial Registration: The study was registered with the Iranian Registry of Clinical Trials (IRCT) under the code IRCT-20191112045413N1.

Abstract
Introduction TPP1 variants have been identified as a causative agent of neuronal ceroid lipofuscinosis 2 disease, that ataxia is one of its clinical features. Therefore, here, molecular study of TPP1 variants is presented in an Iranian cohort and a novel pathogenic variant is described. Methods This investigation was conducted as a cross-sectional study in a tertiary referral hospital, Children's Medical Center, Pediatrics Center of Excellence. Clinical presentations and pedigrees were documented. Patients with cerebellar ataxia were enrolled in this study. Next-generation sequencing was applied to confirm the diagnosis. Segregation and bioinformatics analyses were also done for the variants using Sanger sequencing. Results Forty-five patients were included in our study. The mean age of onset was 104 (+55.60) months (minimum = 31 months, maximum = 216 months). The majority of cases (73.3%) were born to consanguineous parents and only 1 patient (2.2%) had an affected sibling. Of the 45 patients, only 1 patient with a novel pathogenic variant (c.1425_1425+1delinsAT, p.A476Cfs*15) in the TPP1 gene was identified. Discussion The main strength of current study is the relatively large sample size. Besides, a novel pathogenic variant could be important toward the diagnosis and management of this condition. With significant advances in various therapies, early diagnosis could improve the treatments using personalized-based medicine.

Abstract
BACKGROUND Aminoacylase-1 deficiency (ACY1D) is an autosomal recessive rare inborn error of metabolism, which is caused by disease-causing variants in the ACY1. This disorder is characterized by increased urinary excretion of specific N-acetyl amino acids. Affected individuals demonstrate heterogeneous clinical manifestations which are primarily neurologic problems. In neuroimaging, corpus callosum hypoplasia, cerebellar vermis atrophy, and delayed myelination of cerebral white matter have been reported. AIMS Finding disease-causing variant and expanding imaging findings in a patient with persistent basal ganglia involvement. METHODS Whole-exome sequencing was performed in order to identify disease-causing variants in an affected 5-year-old male patient who presented with neurologic regression superimposed on neurodevelopmental delay following a febrile illness. He had inability to walk, cognitive impairment, speech delay, febrile-induced seizures, truncal hypotonia, moderate to severe generalized dystonia, and recurrent metabolic decompensation. RESULTS All metabolic tests were normal except for a moderate metabolic acidosis following febrile illnesses. The results of serial brain magnetic resonance imaging (MRI) at ages 1 and 4.5 years revealed persistent bilateral and symmetric abnormal signals in basal ganglia mainly caudate and globus pallidus nuclei with progression over time in addition to a mild supratentorial atrophy. A homozygous missense variant [NM_000666.3: c.1057C>T; p.(Arg353Cys)] was identified in the ACY1, consistent with aminoacylase-1 deficiency. Variant confirmation in patient and segregation analysis in his family were performed using Sanger sequencing. CONCLUSIONS Our findings expanded the phenotype spectrum of ACY1-related neurodegeneration by demonstrating persistent basal ganglia involvement and moderate to severe generalized dystonia.

Abstract
Background and Aims In the pathophysiology of Guillain-Barre syndrome (GBS), inflammation and immunity are believed to play a key role. The neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), and platelet-lymphocyte ratio (PLR) have been recently identified as potential markers of inflammation or immunity. This study aimed to investigate whether NLR, MLR, and PLR are associated with GBS characteristics in children. We also assessed the impact of the COVID-19 pandemic on the characteristics of GBS in Iran. Methods In this retrospective cross-sectional study, we reviewed the records of all 150 children diagnosed with GBS in the Children's Medical Center hospital affiliated with Tehran University of Medical Sciences (TUMS) from March 2017 until March 2022. The TUMS research ethics committee approved the study (Ethics code: IR.TUMS.CHMC.REC.1399.125). Patients' data including gender, age, clinical symptoms, laboratory findings, and electrodiagnostic study results were collected and analyzed. Results This study involved 150 children, comprising 93 boys and 57 girls, with an average age of 7.53 ± 3.75 years. The analysis demonstrated that the number of hospitalization days increased with an increase in NLR (p = 0.025). Moreover, patients with abnormal electrodiagnostic study patterns had a higher risk of intensive care unit (ICU) admission (p: 0.027), although according to binary logistic regression, respiratory failure at admission time was the only significant factor increasing the risk of ICU admission (p = 0.035). The study also found that the pandemic has resulted in a shift from acute inflammatory demyelinating polyneuropathy to acute motor axonal neuropathy as the most common EMG-NCV pattern in our patients (p < 0.001). Conclusion We found that higher NLR was associated with a longer hospitalization duration and could potentially distinguish between severe and mild cases of GBS. We have also shown that the COVID-19 pandemic has changed our patients' most frequent electromyography and nerve conduction velocity (EMG-NCV) patterns.

Abstract
Leukodystrophies (LDs) are a heterogeneous group of progressive neurological disorders and characterized by primary involvement of white matter of the central nervous system (CNS). This is the first report of the Iranian LD Registry database to describe the clinical, radiological, and genomic data of Persian patients with leukodystrophies. From 2016 to 2019, patients suspicious of LDs were examined followed by a brain magnetic resonance imaging (MRI). A single gene testing or whole-exome sequencing (WES) was used depending on the neuroradiologic phenotypes. In a few cases, the diagnosis was made by metabolic studies. Based on the MRI pattern, diagnosed patients were divided into cohorts A (hypomyelinating LDs) versus cohort B (Other LDs). The most recent LD classification was utilized for classification of diagnosed patients. For novel variants, in silico analyses were performed to verify their pathogenicity. Out of 680 registered patients, 342 completed the diagnostic evaluations. In total, 245 patients met a diagnosis which in turn 24.5% were categorized in cohort A and the remaining in cohort B. Genetic tests revealed causal variants in 228 patients consisting of 213 variants in 110 genes with 78 novel variants. WES and single gene testing identified a causal variant in 65.5% and 34.5% cases, respectively. The total diagnostic rate of WES was 60.7%. Lysosomal disorders (27.3%; GM2-gangliosidosis-9.8%, MLD-6.1%, KD-4.5%), amino and organic acid disorders (17.15%; Canavan disease-4.5%, L-2-HGA-3.6%), mitochondrial leukodystrophies (12.6%), ion and water homeostasis disorders (7.3%; MLC-4.5%), peroxisomal disorders (6.5%; X-ALD-3.6%), and myelin protein disorders (3.6%; PMLD-3.6%) were the most commonly diagnosed disorders. Thirty-seven percent of cases had a pathogenic variant in nine genes (ARSA, HEXA, ASPA, MLC1, GALC, GJC2, ABCD1, L2HGDH, GCDH). This study highlights the most common types as well as the genetic heterogeneity of LDs in Iranian children.

Abstract
BACKGROUND Pathogenic variants in the ATCAY gene are associated with a rare autosomal recessive disorder called Cayman cerebellar ataxia. Affected individuals display psychomotor retardation, cerebellar dysfunction, nystagmus, intention tremor, ataxic gait and dysarthric in some cases. CASE PRESENTATION Whole exome sequencing was performed for a 21-month-old girl suffering from developmental delay specifically in motor and language aspects, hypotonia, nystagmus, pes planus and strabismus. The detected variant in the patient was confirmed by family segregation analysis by Sanger sequencing in both of her parents. Previously three homozygous variants in the ATCAY gene (missense, splice site and frameshift deletion) have been reported in patients with Cayman cerebellar ataxia. Here we report the fourth homozygous variant and the second homozygous frameshift deletion in this gene to be associated with autosomal recessive Cayman cerebellar ataxia. CONCLUSION The identification of this novel homozygous frameshift deletion in the ATCAY gene expands our understanding of the genetic landscape underlying Cayman cerebellar ataxia. Furthermore, the occurrence of this variant in Iran, in addition to Pakistan, signifies the importance of considering genotypic and phenotypic factors beyond ethnicity when studying this disorder. These findings contribute to the ongoing efforts to unravel the molecular basis of Cayman cerebellar ataxia and improve diagnostic approaches and potential therapeutic interventions.

Abstract
BACKGROUND Since the results of previous studies regarding the safety and efficacy of miglustat in GM2 gangliosidosis (GM2g) were inconsistent, we aimed to assess miglustat therapy in GM2g patients. METHODS This study followed the latest version of PRISMA. We included the observational or interventional studies reporting GM2g patients under miglustat therapy by searching PubMed, Web of Science, and Scopus. Data extracted included the natural history of individual patient data, as well as the safety and efficacy of miglustat in GM2g patients. The quality assessment was performed using the Joanna Briggs Institute Critical Appraisal checklist. RESULTS A total of 1023 records were identified and reduced to 621 after removing duplicates. After screening and applying the eligibility criteria, 10 articles and 2 abstracts met the inclusion criteria. Overall, the studies represented 54 patients with GM2g under treatment with miglustat and 22 patients with GM2g in the control group. Among patients with available data, 14 and 54 have been diagnosed with Sandhoff disease and Tay-Sachs disease, respectively. Patients included in this review consisted of 23 infantile, 4 late-infantile, 18 juvenile, and 31 adult-onset GM2g. CONCLUSIONS Although miglustat should not be considered a definite treatment for GM2g, it appears that patients, particularly those with infantile or late-infantile GM2g, could benefit from miglustat therapy to some extent. We also make some suggestions regarding future studies presenting their findings in a standard format to facilitate pooling the available data in such rare diseases for a more comprehensive conclusion.

Abstract
BACKGROUND Phospholipase-associated neurodegeneration (PLAN) caused by mutations in the PLA2G6 gene is a rare neurodegenerative disorder that presents with four sub-groups. Infantile neuroaxonal dystrophy (INAD) and PLA2G6-related dystonia-parkinsonism are the main two subtypes. In this cohort, we reviewed clinical, imaging, and genetic features of 25 adult and pediatric patients harboring variants in the PLA2G6. METHODS An extensive review of the patients' data was carried out. Infantile Neuroaxonal Dystrophy Rating Scale (INAD-RS) was used for evaluating the severity and progression of INAD patients. Whole-exome sequencing was used to determine the disease's underlying etiology followed by co-segregation analysis using Sanger sequencing. In silico prediction analysis based on the ACMG recommendation was used to assess the pathogenicity of genetic variants. We aimed to survey a genotype-genotype correlation in PLA2G6 considering all reported disease-causing variants in addition to our patients using the HGMD database and the chi-square statistical approach. RESULTS Eighteen cases of INAD and 7 cases of late-onset PLAN were enrolled. Among 18 patients with INAD, gross motor regression was the most common presenting symptom. Considering the INAD-RS total score, the mean rate of progression was 0.58 points per month of symptoms (Standard error 0.22, lower 95% - 1.10, and upper 95% - 0.15). Sixty percent of the maximum potential loss in the INAD-RS had occurred within 60 months of symptom onset in INAD patients. Among seven adult cases of PLAN, hypokinesia, tremor, ataxic gate, and cognitive impairment were the most frequent clinical features. Various brain imaging abnormalities were also observed in 26 imaging series of these patients with cerebellar atrophy being the most common finding in more than 50%. Twenty unique variants in 25 patients with PLAN were detected including nine novel variants. Altogether, 107 distinct disease-causing variants from 87 patient were analyzed to establish a genotype-phenotype correlation. The P value of the chi-square test did not indicate a significant relationship between age of disease onset and the distribution of reported variants on PLA2G6. CONCLUSION PLAN presents with a wide spectrum of clinical symptoms from infancy to adulthood. PLAN should be considered in adult patients with parkinsonism or cognition decline. Based on the current knowledge, it is not possible to foresee the age of disease onset based on the identified genotype.

Abstract
BACKGROUND Deficiency of adenosine deaminase 2 (DADA2) is an autosomal recessive autoinflammatory disease caused by mutations in the ADA2 gene. DADA2 has a broad spectrum of clinical presentations. Apart from systemic manifestations, we can categorize most of the signs and symptoms of DADA2 into the three groups of vasculitis, hematologic abnormalities, and immunologic dysregulations. The most dominant vasculitis features are skin manifestations, mostly in the form of livedo racemosa/reticularis, and early onset ischemic or hemorrhagic strokes. Hypogammaglobulinemia that is found in many cases of DADA2 brings immunodeficiencies into the differential diagnosis. Cytopenia, pure red cell aplasia (PRCA), and bone marrow failure (BMF) are the hematologic abnormalities commonly found in DADA. CASE PRESENTATION We introduce eleven patients with DADA2 diagnosis, including two brothers and sisters, one set of twin sisters, and one father and his daughter and son. Ten patients (91%) had consanguineous parents. All the patients manifested livedo racemose/reticularis. Ten patients (91%) reported febrile episodes, and seven (64%) had experienced strokes. Only one patient had hypertension. Two of the patients (11%) presented decreased immunoglobulin levels. One of the patients presented with PRCA. Except for the PRCA patient with G321E mutation, all of our patients delivered G47R mutation, the most common mutation in DADA2 patients. Except for one patient who unfortunately passed away before the diagnosis was made and proper treatment was initiated, the other patients' symptoms are currently controlled; two of the patients presented with mild symptoms and are now being treated with colchicine, and the eight others responded well to anti-TNFs. The PRCA patient still suffers from hematologic abnormalities and is a candidate for a bone marrow transplant. CONCLUSIONS Considering the manifestations and the differential diagnoses, DADA2 is not merely a rheumatologic disease, and introducing this disease to hematologists, neurologists, and immunologists is mandatory to initiate prompt and proper treatment. The efficacy of anti-TNFs in resolving the symptoms of DADA2 patients have been proven, but not for those with hematologic manifestations. Similarly, they were effective in controlling the symptoms of our cohort of patients, except for the one patient with cytopenia.

Abstract
BACKGROUND Spinal muscular atrophy (SMA) could be classified as 5q and non-5q, based on the chromosomal location of causative genes. A rare form of non-5q SMA is an autosomal-recessive condition called spinal muscular atrophy with progressive myoclonic epilepsy (SMA-PME), phenotypically characterized by myoclonic and generalized seizures with progressive neurological deterioration. SMA-PME is a clinically heterogeneous disorder that arises from biallelic pathogenic variants in ASAH1 gene. METHODS Following clinical and primary laboratory assessments, whole-exome sequencing was performed to detect the disease-causing variants in three cases of SMA-PME from different families. Also, Multiplex ligation-dependent probe amplification (MLPA) was employed for determining the copy numbers of SMN1 and SMN2 genes to rule out 5q SMA. RESULTS Exome sequencing revealed two different homozygous missense mutations (c.109 C > A [p.Pro37Thr] or c.125 C > T [p.Thr42Met]) in exon 2 of the ASAH1 gene in the affected members of the families. Sanger sequencing of the other family members showed the expected heterozygous carriers. In addition, no clinically relevant variant was identified in patients by MLPA. CONCLUSION This study describes two different ASAH1 mutations and the clinical picture of 3 SMA-PME patients. In addition, previously reported mutations have been reviewed. This study could help to fortify the database of this rare disease with more clinical and genomic data.

Abstract
BACKGROUND Giant axonal neuropathy (GAN) is a progressive childhood hereditary polyneuropathy that affects both the peripheral and central nervous systems. Disease-causing variants in the gigaxonin gene (GAN) cause autosomal recessive giant axonal neuropathy. Facial weakness, nystagmus, scoliosis, kinky or curly hair, pyramidal and cerebellar signs, and sensory and motor axonal neuropathy are the main symptoms of this disorder. Here, we report two novel variants in the GAN gene from two unrelated Iranian families. METHODS Clinical and imaging data of patients were recorded and evaluated, retrospectively. Whole-exome sequencing (WES) was undertaken in order to detect disease-causing variants in participants. Confirmation of a causative variant in all three patients and their parents was carried out using Sanger sequencing and segregation analysis. In addition, for comparing to our cases, we reviewed all relevant clinical data of previously published cases of GAN between the years 2013-2020. RESULTS Three patients from two unrelated families were included. Using WES, we identified a novel nonsense variant [NM_022041.3:c.1162del (p.Leu388Ter)], in a 7-year-old boy of family 1, and a likely pathogenic missense variant [NM_022041.3:c.370T>A (p.Phe124Ile)], in two affected siblings of the family 2. Clinical examination revealed typical features of GAN-1 in all three patients, including walking difficulties, ataxic gait, kinky hair, sensory-motor polyneuropathy, and nonspecific neuroimaging abnormalities. Review of 63 previously reported cases of GAN indicated unique kinky hair, gait problem, hyporeflexia/areflexia, and sensory impairment were the most commonly reported clinical features. CONCLUSIONS One homozygous nonsense variant and one homozygous missense variant in the GAN gene were discovered for the first time in two unrelated Iranian families that expand the mutation spectrum of GAN. Imaging findings are nonspecific, but the electrophysiological study in addition to history is helpful to achieve the diagnosis. The molecular test confirms the diagnosis.

Abstract
BACKGROUND COVID-19 infection and its neurological manifestations were seen in children although less common than adults. The aim of this study was to determine the frequency of different types of neurologic findings of hospitalized children with COVID-19. ]. METHODS This retrospective study was performed on hospitalized pediatric patients aged≤18 years with confirmed SARS-CoV-2 at Children's Medical Center Hospital. Neurological manifestations were defined as the presence of any of the following symptoms: seizure, altered mental status, behavioral/personality change, ataxia, stroke, muscle weakness, smell and taste dysfunctions, and focal neurological disorders. RESULTS Fifty-four children with COVID-19 were admitted and their mean age was 6.94±4.06 years. Thirty-four of them (63%) were male. The most frequent neurological manifestation was seizure (19 [45%]) followed by muscle weakness (11 [26%]), loss of consciousness (10 [23%]), and focal neurological disorders (10 [23%]). Other neurological manifestations consisted of headache (n=7), movement disorders (n=6), behavioral/personality change (n=5), ataxia (n=3), and stroke (n=3). Twenty-nine percent of our patients had leukocytosis. A neutrophil count above 70% was seen in 31% of participants. Among our patients, 81% had a positive reverse-transcription polymerase chain reaction (RT-PCR) test for SARS-CoV-2. CONCLUSION During the current pandemic outbreak, hospitalized children with COVID-19 should be evaluated for neurological signs because it is common among them and should not be under-estimated.

Abstract
Spinal muscular atrophy (SMA) is among the most common autosomal recessive disorders with different incidence rates in different ethnic groups. In the current study, we have determined SMN1, SMN2 and NAIP copy numbers in an Iranian population using MLPA assay. Cases were recruited from Genome-Nilou Laboratory, Tehran, Iran and Pars-Genome Laboratory, Karaj, Iran during 2012-2022. All enrolled cases had a homozygous deletion of exon 7 of SMN1. Moreover, except for 11 cases, all other cases had a homozygous deletion of exon 8 of SMN1. Out of 186 patients, 177 (95.16%) patients showed the same copy numbers of exons 7 and 8 of SMN2 gene. In addition, 53 patients (28.49%) showed 2 copies, 71 (38.17%) showed 3 copies and 53 patients (28.49%) showed 4 copies of SMN2 gene exons 7 and 8. The remaining 9 patients showed different copy numbers of exons 7 and 8 of SMN2 gene. The proportions of SMA patients with different numbers of normal NAIP were 0 copy in 73 patients (39.24%), 1 copy in 59 patients (31.72%), 2 copies in 53 patients (28.49%) and 4 copies in one patient (0.5%). These values are different from values reported in other populations. Integration of the data of the SMN1/2 and NAIP genes showed 17 genotypes. Patients with genotype 0-0-3-3-1 (0 copies of SMN1 (E7,8), 3 copies of SMN2 (E7,8) and 1 copy of NAIP (E5)) were the most common genotype in this study. Patients with 0-0-2-2-0 genotype were more likely to have type I SMA. The results of the current study have practical significance, particularly in the genetic counseling of at-risk families.

Abstract
Background and Aims Due to increased rate of open-heart surgeries in children, postsurgical mortality and morbidities have increasingly gained attention. Neurological complications are some of the most important postsurgical events. However, the number of studies regarding postsurgical neurological complications seems to be inadequate. We aimed to study the incidence of neurological complications following cardiac surgery in the pediatric cardiac intensive care unit (ICU) of the children's medical center. Methods This cross-sectional study was conducted from March to September 2019. We included all of the children who underwent cardiac surgery and were admitted to ICU at CMC. We collected their demographic data, lab test results (white blood cell count, absolute neutrophile and lymphocyte counts) and calculated their Risk Adjustment for Congenital Heart Surgery (RACHS) score. We then documented neurological adverse events and investigated the associations between those events and the patients' data. Results Of the 267 studied patients, 14 developed neurological complications (5.2%); seven developed chorea (2.6%), four developed seizures (1.5%), and two developed both seizure and chorea (0.7%). One case developed subarachnoid hemorrhage (SAH). We observed that age (p = 0.000), weight (p = 0.000), and RACHS score (p = 0.006) were associated with the development of neurological complications. Additionally, we observed that "neutrophil to lymphocyte ratio" was not associated with the risk of postsurgical neurological complications. Conclusion Younger age, lower weight, and higher RACHS score were associated with neurological complications after operations. Given the importance of postsurgical neurological complications, further investigations should be carried out to cover this issue and discover preventive strategies for such morbidities.

Abstract
BACKGROUND Insufficient amounts of survival motor neuron protein is leading to one of the most disabling neuromuscular diseases, spinal muscular atrophy (SMA). Before the current study, the detailed characteristics of Iranian patients with SMA had not been determined. OBJECTIVE To describe the key demographic, clinical, and genetic characteristics of patients with SMA registered in the Iranian Registry of SMA (IRSMA). METHODS IRSMA has been established since 2018, and the demographic, clinical, and genetic characteristics of patients with SMA were recorded according to the methods of treat neuromuscular disease (TREAT-NMD) project. RESULTS By October 1, 2022, 781 patients with 5q SMA were registered. Of them, 164 patients died, the majority of them had SMA type 1 and died during the first 20 months of life. The median survival of patients with type 1 SMA was 23 months. The consanguinity rate in 617 alive patients was 52.4%, while merely 24.8% of them had a positive family history. The most common type of SMA in live patients was type 3. Morbidities were defined as having scoliosis (44.1%), wheelchair dependency (36.8%), tube feeding (8.1%), and requiring mechanical ventilation (9.9%). Most of the registered patients had a homozygous deletion of SMN1, while the frequency of patients with higher copy numbers of SMN2, was less in more severe types of the disease. Earlier onset of the disease was significantly seen in patients with lower copy numbers of SMN2. The neuronal apoptosis inhibitory protein (NAIP) gene deletion was associated with a higher incidence of more severe types of SMA, higher dependency on ventilators, tube feeding, and earlier onset of the disease. CONCLUSIONS The IRSMA is the first established Iranian nationwide registry of patients with SMA. Using this registry, decision-makers, researchers, and practitioners can precisely understand the epidemiology, characteristics, and genetics of patients with SMA in Iran.

Abstract
We reported an association between SARS-CoV-2 infection and Guillain-Barre syndrome (GBS). From 37 patients with GBS, previous SARS-CoV-2 clinical clues, including fever, cough, and diarrhea, were recorded in 18 patients. Among them, SARS-CoV-2 IgG was detected in seven patients, considered confirmed as cases. SARS-CoV-2 PCR was positive in just one patient. Although we found no increase in patient recruitment during the pandemic compared to previous years, our study indicated that SARS-CoV-2 is associated with poorer outcomes regarding GBS disability scale and hospital stay.

Abstract
OBJECTIVES This study aimed to analyze the health-related quality of life (HRQoL) of patients with spinal muscular atrophy (SMA) based on the type of SMA, demographic and clinical features and compare HRQoL of these patients with a matched healthy control group. METHODS: This was a case-control study of Patients with SMA in Iran. Sixty-six patients with SMA type II and III aged 8-18 years and also 264 healthy age, sex, and socio-economic matched individuals were enrolled. To assess the quality of life, we used the Persian version of the KIDSCREEN-27. RESULTS The health-related quality of life between children with type II and type III SMA was not significant in all 5 subscales. However, HRQoL in healthy children was significantly higher than in SMA children in all 5 subscales. CONCLUSION The quality of life in children with SMA was lower than the healthy control group in all subscales, and physical well-being and psychosocial aspects are the main domains of life impaired by SMA disease. However, no significant difference between the quality of life in children with SMA type II and type III was observed.

Abstract
Background Considering the importance of spiritual aspects of human beings, spiritual care provision is increasingly recognized as a major duty of healthcare providers, particularly nursing staff. Spiritual care competence is necessary for the nurses to be able to provide spiritual care, but the competence itself is associated with other variables. This study aimed to investigate if the spiritual care competence of nurses is related to their spiritual health. Methods A cross-sectional study was conducted with the participation of 172 practicing nurses in hospitals affiliated with Qom University of Medical Sciences, selected through stratified random sampling. Participants completed the Persian versions of the Spiritual Health Questionnaire (Amiri) and the Spiritual Care Competence Scale (Van Leeuwen). To examine the correlation between nurses’ spiritual health and spiritual care competence, a Spearman coefficient was used and a linear regression analysis was done to determine the predictability of the spiritual care competence of the nurses. The data were analyzed using SPSS v.23 and the significance level was set at 0.05. Results The participants showed a mean (SD) score of 108.93 (19.04) on spiritual care competence and 213.38 (16.49) on spiritual health. Spiritual care competence of nurses showed no significant relationship with demographic characteristics and their spiritual health had a significant relationship with gender only. Correlation analysis revealed a significant relationship between spiritual health and spiritual care competence and their subscales. Moreover, the linear regression analysis indicated that the nurses’ performance regarding spiritual health can predict their spiritual care competence. Conclusion The study revealed that the spiritual care competence of nurses is correlated with their spiritual health and performance as a subscale of spiritual health can predict their spiritual care competence. Thus, it can be concluded that the spiritual health of nurses is an important factor in providing spiritual care for patients and meeting their spiritual needs.

Abstract
BACKGROUND An overview of spiritual care studies can help reveal the dimensions of spiritual care and summarize the findings of available studies. Thus, we designed the present study based on existing studies to explain the dimensions of spiritual care. MATERIALS AND METHODS In this thematic analysis, we gathered the related articles published in Persian and English in the last 8 years (2013-2021) with the help of the keywords of Care, Support, Spirituality, Religion, Treatment, Hospice, and Palliative, and searching in electronic databases, including PubMed, Scopus, Web Of Sciences, Magiran, Islamic Science Citation (ISC), and Scientific Information Database (SID). We accurately studied 79 articles that met the inclusion criteria, and then the spiritual care components were extracted and coded, and finally, the codes were categorized as themes and sub-theme. RESULTS Thematic analysis of available studies revealed that the dimensions (theme) of spiritual care include: spiritual and religious assessment, developing a structure for providing spiritual care, establishing effective and supportive communication with the patient, training the patient, answering his questions, encouraging, maintaining, and improving social communications, encouraging the patient to live happily, helping the patient to achieve peace and calmness, supporting for spiritual rituals and activities, supporting and training the patient's family, and supporting the dying patient. CONCLUSIONS Spiritual care includes various and numerous dimensions. Considering the widespread dimensions of spiritual care, it seems necessary to design and plan appropriate studies to reveal other spiritual care dimensions from the perspective of patients and care providers in different cultures.

Abstract
Autosomal recessive spastic ataxia of Charlevoix Saguenay (ARSACS) is now increasingly identified from all countries over the world, possibly rendering it one of the most common autosomal recessive ataxias. Here, we selected patients harboring SACS variants, the causative gene for ARSACS, in a large cohort of 137 patients with early-onset ataxia recruited from May 2019 to May 2021 and were referred to the ataxia clinic. Genetic studies were performed for 111 out of 137 patients (81%) which led to a diagnostic rate of 72.9% (81 out of 111 cases). Ten patients with the molecular diagnosis of ARSACS were identified. We investigated the phenotypic and imaging spectra of all confirmed patients with ARSACS. We also estimated the frequency of ARSACS in this cohort and described their clinical and genetic findings including seven novel variants as well as novel neuroimaging findings. While the classic clinical triad of ARSACS is progressive cerebellar ataxia, spasticity, and sensorimotor polyneuropathy, it is not a constant feature in all patients. Sensorimotor axonal-demyelinating neuropathy was detected in all of our patients, but spasticity and extensor plantar reflex were absent in 50% (5/10). In all patients, brain magnetic resonance imaging (MRI) showed symmetric linear hypointensities in the pons (pontine stripes) and anterior superior cerebellar atrophy as well as a hyperintense rim around the thalami (thalamic rim). Although infratentorial arachnoid cyst has been reported in ARSACS earlier, we report anterior temporal arachnoid cyst in two patients for the first time, indicating that arachnoid cyst may be an associated imaging feature of ARSACS. We also extended molecular spectrum of ARSACS by presenting 8 pathogenic and one variant of unknown significance (VUS) sequence variants, which 7 of them have not been reported previously. MetaDome server confirmed that the identified VUS variant was in the intolerant regions of sacsin protein encoded by SACS.

Abstract
BACKGROUND Duchenne muscular dystrophy (DMD) is the most common muscular dystrophy in the pediatric population. The manifestations of this disease include progressive muscle weakness, gait dysfunction, and motor impairment, leading to a loss of ambulation by the age of 13 years. Molecular diagnosis is the standard diagnostic tool for DMD. This study aimed to investigate disease progression and genetic patterns in Iranian ambulant boys and to find the correlation between genotypes and motor function phenotypes. METHODS This study was performed on 152 DMD patients. Clinical history, including the disease phenotype, steroid therapy, and the North Star Ambulatory Assessment (NSAA) score, was taken for all the patients. Molecular diagnoses were confirmed by multiplex ligation-dependent probe amplification and next-generation sequencing tests. RESULTS A total of 152 Iranian DMD patients were examined in this study. The mean age at the time of disease onset was 4.04 ± 2.00 years, and the mean age at diagnosis was 5.05 ± 2.08 years. The mean age of ambulation loss was 10.9 years. Contracture was reported in 38.9% of cases. In terms of age, the mean total NSAA score showed a peak at 4 years of age, with a mean NSAA score of 24. Annual changes in the NSAA score were determined for all cases, based on the mutation type and exon site. Deletion mutation was found in 79.1% of cases, duplication in 6.8%, nonsense in 12.8%, and splice site in 1.4%. The most common single exon deletion was exon 44 (5.3%), and the most common multiexon deletions were attributed to exons 45-50 and exons 45-52 (4.6%). The results did not indicate any correlation between the mutation type and age at the time of disease onset, loss of ambulation age, and wheelchair dependence; however, a significant association was found between contracture and mutation type. The results showed a significant difference in the NSAA score between the deletion and nonsense groups at the age of 3 years (P = 0.04). No significant correlation was found between the phenotype and exon site. Overall, 91.1% of the study population had a history of corticosteroid use, and 54.1% showed compliance with rehabilitation therapy. CONCLUSION This study demonstrated the phenotypes and mutational features of Iranian DMD boys and provided information regarding the natural motor history of the disease, disease progression, diagnosis, and status of DMD management in Iran. The present findings can promote the development of clinical trials and future advanced molecular therapies in Iran.

Abstract
INTRODUCTION The current multi-center, randomized, double-blind study was conducted among children with cerebral palsy (CP) to assess the safety and efficacy of umbilical cord blood mononuclear cell (UCB-MNC). We performed the diffusion tensor imaging to assess the changes in the white matter structure. METHODS Males and females aged 4 to 14 years old with spastic CP were included. Eligible participants were allocated in 4:1 ratio to be in the experimental or control groups; respectively. Individuals who were assigned in UCB-MNC group were tested for human leukocyte antigen (HLA) and fully-matched individuals were treated with UCB-MNCs. A single dose (5 × 106 /kg) UCB-MNCs were administered via intrathecal route in experimental group. The changes in gross motor function measure (GMFM)-66 from baseline to one year after treatment were the primary endpoints. The mean changes in modified Ashworth scale (MAS), pediatric evaluation of disability inventory (PEDI), and CP quality of life (CP-QoL) were also evaluated and compared between groups. The mean changes in fractional anisotropy (FA) and mean diffusivity (MD) of corticospinal tract (CST) and posterior thalamic radiation (PTR) were the secondary endpoints. Adverse events were safety endpoint. RESULTS There were 72 included individuals (36 cases in each group). The mean GMFM-66 scores increased in experimental group; compared to baseline (+ 9.62; 95%CI: 6.75, 12.49) and control arm (β: 7.10; 95%CI: 2.08, 12.76; Cohen's d: 0.62) and mean MAS reduced in individuals treated with UCB-MNCs compared to the baseline (-0.87; 95%CI: -1.2, -0.54) and control group (β: -0.58; 95%CI: -1.18, -0.11; Cohen's d: 0.36). The mean PEDI scores and mean CP-QoL scores in two domains were higher in the experimental group compared to the control. The imaging data indicated that mean FA increased and MD decreased in participants of UCB-MNC group indicating improvements in white matter structure. Lower back pain, headaches, and irritability were the most common adverse events within 24 h of treatment that were related to lumbar puncture. No side effects were observed during follow-up. CONCLUSIONS This trial showed that intrathecal injection of UCB-MNCs were safe and effective in children with CP. TRIAL REGISTRATION The study was registered with ClinicalTrials.gov ( NCT03795974 ).

Abstract
Introduction Coenzyme Q10 deficiency can be due to mutations in Coenzyme Q10-biosynthesis genes (primary) or genes unrelated to biosynthesis (secondary). Primary Coenzyme Q10 deficiency-4 (COQ10D4), also known as autosomal recessive spinocerebellar ataxia-9 (SCAR9), is an autosomal recessive disorder caused by mutations in the ADCK3 gene. This disorder is characterized by several clinical manifestations such as severe infantile multisystemic illness, encephalomyopathy, isolated myopathy, cerebellar ataxia, or nephrotic syndrome. Methods In this study, whole-exome sequencing was performed in order to identify disease-causing variants in an affected girl with developmental regression and Epilepsia Partialis Continua (EPC). Next, Sanger sequencing method was used to confirm the identified variant in the patient and segregation analysis in her parents. Case Presentation The proband is an affected 11-year-old girl with persistent seizures, EPC, and developmental regression including motor, cognition, and speech. Seizures were not controlled with various anticonvulsant drugs despite adequate dosing. Progressive cerebellar atrophy, stroke-like cortical involvement, multifocal hyperintense bright objects, and restriction in diffusion-weighted imaging (DWI) were seen in the brain magnetic resonance imaging (MRI). Conclusions A novel homozygous missense variant [NM_020247.5: c.814G>T; (p.Gly272Cys)] was identified within the ADCK3 gene, which is the first mutation in this gene in the Iranian population. Bioinformatics analysis showed this variant is damaging. Based on our patient, clinicians should consider genetic testing earlier to instant diagnosis and satisfactory treatment based on exact etiology to prevent further neurologic sequelae.

Abstract
Background In line with the significance of organizational commitment, the question arises "Do spiritual health and psychological well-being optimize teachers' organizational commitment?" The purpose of this study was to determine the relationship between spiritual health, psychological well-being and the organizational commitment of high school teachers. Methods This was a cross-sectional study in which, 346 teachers in Tehran high schools participated through multi-stage sampling. The data were collected using Ryff Psychological Well-being Questionnaire (1989), Spiritual Health Questionnaire in Iranian Society (2014) and Organizational Commitment scale of Allen and Meyer (1990), and their relationships were assessed. Results Psychological well-being and spiritual health had positive and significant relationship with teachers' organizational commitment. Furthermore, approximately 50% of variations in organizational commitment subscales could be explained by the variables of spiritual health and psychological well-being. Conclusion Psychological well-being and spiritual health can predict organizational commitment as the dependent variable among high school teachers.

Background
Peripheral arterial disease (PAD) is a common manifestation of systemic atherosclerosis which strongly correlates to cardiovascular morbidity and mortality and increased risk of limb loss, and despite the wide use of guideline-based antiplatelet therapy, patients remain at high risk for cardiovascular and limb events. There has been increasing interest in novel anticoagulants to improve prevention of complications secondary to PAD.
Purpose
This study aims to determine the effectiveness and safety of combined direct oral anticoagulant plus antiplatelet in reducing MACE, MALE and all-cause mortality among patients with PAD.
Method
Randomized controlled trials with outcomes on major adverse cardiac events (MACE), major adverse limb events (MALE), all-cause mortality and bleeding were searched through PubMed, Cochrane and EBSCOHost.
Result
Pooled analysis of studies on patients peripheral arterial disease showed that anticoagulant combined with antiplatelet have significant benefits compared with antiplatelet alone in reducing major adverse limb events (RR 0.72, 95% CI 0.62 to 0.83) and stroke (RR 0.74, 95% CI 0.57 to 0.97) but had inconclusive results in reducing myocardial infarction (RR 0.85, 95% CI 0.70 to 1.03).There was no significant benefit in reducing cardiovascular death (RR 1.04, 95% CI 0.88 to 1.23) and all-cause mortality (RR 1.02, 95% CI 0.90 to 1.16). Likewise, there was increased risk of bleeding (RR 1.46, 95% CI of 1.18 to 1.80) compared with antiplatelet alone.
Conclusion
Anticoagulant (Rivaroxaban) combined with antiplatelet (aspirin) as alternative to traditional antiplatelet (aspirin) therapy significantly reduced major adverse limb events and stroke. However, there was a higher incidence of bleeding for the combined cohort. Therefore, it is deemed necessary to identify high-risk PAD patients with low risk of bleeding who can benefit the most with the combined intervention.

Abstract
Accurately predicting clinical outcome of aneurysmal subarachnoid hemorrhage (aSAH) patients is difficult. The purpose of this study was to develop and test a new fully-automated computer-aided detection (CAD) scheme of brain computed tomography (CT) images to predict prognosis of aSAH patients. A retrospective dataset of 59 aSAH patients was assembled. Each patient had 2 sets of CT images acquired at admission and prior-to-discharge. CAD scheme was applied to segment intracranial brain regions into four subregions, namely, cerebrospinal fluid (CSF), white matter (WM), gray matter (GM), and leaked extraparenchymal blood (EPB), respectively. CAD then detects sulci and computes 9 image features related to 5 volumes of the segmented sulci, EPB, CSF, WM, and GM and 4 volumetrical ratios to sulci. Subsequently, applying a leave-one-case-out cross-validation method embedded with a principal component analysis (PCA) algorithm to generate optimal feature vector, 16 support vector machine (SVM) models were built using CT images acquired either at admission or prior-to-discharge to predict each of eight clinically relevant parameters commonly used to assess patients' prognosis. Finally, a receiver operating characteristics (ROC) method was used to evaluate SVM model performance. Areas under ROC curves of 16 SVM models range from 0.62 ± 0.07 to 0.86 ± 0.07. In general, SVM models trained using CT images acquired at admission yielded higher accuracy to predict short-term clinical outcomes, while SVM models trained using CT images acquired prior-to-discharge demonstrated higher accuracy in predicting long-term clinical outcomes. This study demonstrates feasibility to predict prognosis of aSAH patients using new quantitative image markers generated by SVM models.

Abstract
Background and Objectives: Patients have certain rights that are expected to be observed and respected by healthcare providers. These rights include universal as well as local rights determined by the social and cultural context of any society. Patient’s rights consist of statements issued to declare the duties of the health providers pertaining to patients. There are charters of patient rights in different countries including Iran. However, it seems necessary to investigate more exactly the patient rights in accordance with the Islamic perspective as the fundamental value system of the country. This study was conducted to explore and explain the patient’s rights from the clerics’ point of view. Methods: This was a conventional qualitative content analysis study. The participants were 20 clerics living in Qom selected through purposeful sampling, who met the inclusion criteria and could provide their understanding of the patient’s rights in the context of Islam. Deep semi-structured interviews were conducted. The interviews were coded and categorized through qualitative content analysis. Results: This study led to the identification of four themes as the main features of patient’s rights from the clerics’ point of view including respect for patient autonomy, considering non-physical needs of patients, high-quality healthcare, and moral conduct. Conclusion: According to the findings of this study, patient rights from the viewpoint of the clerics includes besides attending other needs of patients, their spiritual needs that should be addressed by healthcare providers.

Abstract
BACKGROUND Endovascular mechanical thrombectomy (EMT) is an effective method to treat acute ischemic stroke (AIS) patients due to large vessel occlusion (LVO). However, stratifying AIS patients who can and cannot benefit from EMT remains a clinical challenge. OBJECTIVE To develop a new quantitative image marker computed from pre-intervention computed tomography perfusion (CTP) images and evaluate its feasibility to predict clinical outcome among AIS patients undergoing EMT after diagnosis of LVO. METHODS A retrospective dataset of 31 AIS patients with pre-intervention CTP images is assembled. A computer-aided detection (CAD) scheme is developed to pre-process CTP images of different scanning series for each study case, perform image segmentation, quantify contrast-enhanced blood volumes in bilateral cerebral hemispheres, and compute features related to asymmetrical cerebral blood flow patterns based on the cumulative cerebral blood flow curves of two hemispheres. Next, image markers based on a single optimal feature and machine learning (ML) models fused with multi-features are developed and tested to classify AIS cases into two classes of good and poor prognosis based on the Modified Rankin Scale. Performance of image markers is evaluated using the area under the ROC curve (AUC) and accuracy computed from the confusion matrix. RESULTS The ML model using the neuroimaging features computed from the slopes of the subtracted cumulative blood flow curves between two cerebral hemispheres yields classification performance of AUC = 0.878±0.077 with an overall accuracy of 90.3%. CONCLUSIONS This study demonstrates feasibility of developing a new quantitative imaging method and marker to predict AIS patients' prognosis in the hyperacute stage, which can help clinicians optimally treat and manage AIS patients.

Abstract
In this study, a novel methodology for detecting fuzzy optimal solutions of fuzzy optimal control problems governed by fuzzy differential equations is presented. For this purpose, first the concept of optimal solution is proposed by considering a partial ordering on fuzzy numbers space which is based on a new parametric representation for α-level set of fuzzy numbers. Using this partial ordering and parametric representation, the discussed fuzzy optimal control problems are reduced to general optimal control problems in parametric form. Then by Pontryagin’s principle, a candidate for the solution of the original problem is derived. The procedure of extracting candidate solution is illustrated for two experimental problems, which improve the recent results of Refs. 10 and 17.

Abstract
BACKGROUND This study assessed the safety and efficacy of intrathecal injection of umbilical cord tissue mesenchymal stem cells (UCT-MSC) in individuals with cerebral palsy (CP). The diffusion tensor imaging (DTI) was performed to evaluate the alterations in white-matter integrity. METHODS Participants (4-14 years old) with spastic CP were assigned in 1:1 ratio to receive either UCT-MSC or sham procedure. Single-dose (2 × 107) cells were administered in the experimental group. Small needle pricks to the lower back were performed in the sham-control arm. All individuals were sedated to prevent awareness. The primary endpoints were the mean changes in gross motor function measure (GMFM)-66 from baseline to 12 months after procedures. The mean changes in the modified Ashworth scale (MAS), pediatric evaluation of disability inventory (PEDI), and CP quality of life (CP-QoL) were also assessed. Secondary endpoints were the mean changes in fractional anisotropy (FA) and mean diffusivity (MD) of corticospinal tract (CST) and posterior thalamic radiation (PTR). RESULTS There were 36 participants in each group. The mean GMFM-66 scores after 12 months of intervention were significantly higher in the UCT-MSC group compared to baseline (10.65; 95%CI 5.39, 15.91) and control (β 8.07; 95%CI 1.62, 14.52; Cohen's d 0.92). The increase was also seen in total PEDI scores (vs baseline 8.53; 95%CI 4.98, 12.08; vs control: β 6.87; 95%CI 1.52, 12.21; Cohen's d 0.70). The mean change in MAS scores after 12 months of cell injection reduced compared to baseline (-1.0; 95%CI -1.31, -0.69) and control (β -0.72; 95%CI -1.18, -0.26; Cohen's d 0.76). Regarding CP-QoL, mean changes in domains including friends and family, participation in activities, and communication were higher than the control group with a large effect size. The DTI analysis in the experimental group showed that mean FA increased (CST 0.032; 95%CI 0.02, 0.03. PTR 0.024; 95%CI 0.020, 0.028) and MD decreased (CST -0.035 × 10-3; 95%CI -0.04 × 10-3, -0.02 × 10-3. PTR -0.045 × 10-3; 95%CI -0.05 × 10-3, -0.03 × 10-3); compared to baseline. The mean changes were significantly higher than the control group. CONCLUSIONS The UCT-MSC transplantation was safe and may improve the clinical and imaging outcomes. TRIAL REGISTRATION The study was registered with ClinicalTrials.gov ( NCT03795974 ).

Abstract
BACKGROUND Spirituality is recognized as an important issue in health care, and every individual has spiritual needs. Despite increased knowledge about spiritual care and its necessity, there is no unique agreed-upon framework for spiritual care among the practitioners. This study aimed to explore the concept from the viewpoint of both health-care providers and patients within the Iranian social, cultural and overall contexts and present a charter for providing spiritual care. METHODS The first phase of the study was a systematic literature review. The next phase consisted of two qualitative studies on the components of spiritual care from the perspective of healthcare providers and its dimensions as perceived by patients. The findings were then integrated to make up a charter draft that was accredited through expert opinion. RESULTS The review of literatures led to the identification of two main themes and 10 themes. Perspectives of health-care providers were categorized into four main themes and 10 themes, and patients' opinions were classified into three main themes and 11 themes. The themes and their subthemes were integrated to build the concepts and form the proposed charter with 30 statements. CONCLUSION The charter of spiritual care for patients is intended to present an agreed-upon framework for spiritual care delivery and resolve some of the problems in this path. This can improve health-care delivery system.

Abstract
Background Leukodystrophies are the main subgroup of inherited CNS white matter disorders which cause significant mortality and morbidity in early years of life. Diagnosis is mostly based on clinical context and neuroimaging findings; however, genetic tools, particularly whole-exome sequencing (WES), have led to comprehending the causative gene and molecular events contributing to these disorders. Mutation in Alkaline Ceramidase 3 (ACER3) gene which encodes alkaline ceramidase enzyme that plays a crucial role in cellular growth and viability has been stated as an uncommon reason for inherited leukoencephalopathies. Merely only two ACER3 mutations in cases of progressive leukodystrophies have been reported thus far. Results In the current study, we have identified three novel variants in ACER3 gene in cases with new neurological manifestations including developmental regression, dystonia, and spasticity. The detected variants were segregated into family members. Conclusion Our study expands the clinical, neuroimaging, electroencephalographic, and genetic spectrum of ACER3 mutations. Furthermore, we reviewed and compared the findings of all the previously reported cases and the cases identified here in order to facilitate their diagnosis and management.

Abstract
Complex III (CIII) is the third out of five mitochondrial respiratory chain complexes residing at the mitochondrial inner membrane. The assembly of 10 subunits encoded by nuclear DNA and one by mitochondrial DNA result in the functional CIII which transfers electrons from ubiquinol to cytochrome c. Deficiencies of CIII are among the least investigated mitochondrial disorders and thus clinical spectrum of patients with mutations in CIII is not well defined. We report on a 10-year-old girl born to consanguineous Iranian parents presenting with recurrent visual loss episodes and optic nerve contrast enhancement in brain imaging reminiscent of an acquired demyelination syndrome (i.e. optic neuritis or multiple sclerosis), who was ultimately confirmed to have a novel homozygous missense variant of unknown significance, c.949C > T; p.(Arg317Trp) in the CYC1 gene, a nuclear DNA subunit of complex III of the mitochondrial chain. Sanger sequencing confirmed the segregation of this variant with disease in the family. The effect of this variant on the protein structure was shown in-silico. Our findings, not only expand the clinical spectrum due to defects in CYC1 gene but also highlight that mitochondrial respiratory chain disorders could be considered as a potential differential diagnosis in children who present with unusual patterns of acquired demyelination syndromes (ADS). In addition, our results support the hypothesis that mitochondrial disorders might have an overlapping presentation with ADS.

Abstract
Objective: High prevalence of behavioral and psychological disorders in children with thalassemia can be associated with a decrease in the self-esteem of patients and can completely alter the person's self-concept. The aim of this study was to determine the prevalence of behavioral problems and its relationship with self-esteem and self-concept in patients with thalassemia major aged 6 to 18 years. Method: In a cross-sectional study, 30 patients with thalassemia major at the age of 6 to 18 years were enrolled. behavioral problems, self-esteem, and self-concept were evaluated by the child's behavioral check list at the ages of 6 to 18 years (CBCL 6-18), the Coopersmith's Self-Esteem Inventory, and the Piers-Harris Children's Self-Concept Scale. Results: A total of 10.0% of patients had behavioral disorders, 3 (10.0%) desirable self-esteem, 15 (50.0%) moderate self-esteem, and 12 (40.0%) poor self-esteem. There was a strong but adverse correlation between behavioral disorder score and both self-esteem score (correlation coefficient equal to -0.886, p value = 0.001) and self-concept score (correlation coefficient equal to -0.498, p value = 0.001), and thus those patients with behavioral disorder had less appropriate self-esteem and self-concept. Conclusion: The incidence of behavioral disorders is associated with decreased self-esteem and poor self-concept in these patients. Therefore, improvement in behavioral disorders can be expected by improving self-esteem and self-concept in such patients.

Abstract
Chest-X ray (CXR) radiography can be used as a first-line triage process for non-COVID-19 patients with pneumonia. However, the similarity between features of CXR images of COVID-19 and pneumonia caused by other infections makes the differential diagnosis by radiologists challenging. We hypothesized that machine learning-based classifiers can reliably distinguish the CXR images of COVID-19 patients from other forms of pneumonia. We used a dimensionality reduction method to generate a set of optimal features of CXR images to build an efficient machine learning classifier that can distinguish COVID-19 cases from non-COVID-19 cases with high accuracy and sensitivity. By using global features of the whole CXR images, we successfully implemented our classifier using a relatively small dataset of CXR images. We propose that our COVID-Classifier can be used in conjunction with other tests for optimal allocation of hospital resources by rapid triage of non-COVID-19 cases.

Abstract
In the Hamiltonian adaptive resolution simulation method (H-AdResS) it is possible to simulate coexisting atomistic (AT) and ideal gas representations of a physical system that belong to different subdomains within the simulation box. The Hamiltonian includes a field that bridges both models by smoothly switching on (off) the intermolecular potential as particles enter (leave) the AT region. In practice, external one-body forces are calculated and applied to enforce a reference density throughout the simulation box, and the resulting external potential adds up to the Hamiltonian. This procedure suggests an apparent dependence of the final Hamiltonian on the system's thermodynamic state that challenges the method's statistical mechanics consistency. In this paper, we explicitly include an external potential that depends on the switching function. Hence, we build a grand canonical potential for this inhomogeneous system to find the equivalence between H-AdResS and density functional theory (DFT). We thus verify that the external potential inducing a constant density profile is equal to the system's excess chemical potential. Given DFT's one-to-one correspondence between external potential and equilibrium density, we find that a Hamiltonian description of the system is compatible with the numerical implementation based on enforcing the reference density across the simulation box. In the second part of the manuscript, we focus on assessing our approach's convergence and computing efficiency concerning various model parameters, including sample size and solute concentrations. To this aim, we compute the excess chemical potential of water, aqueous urea solutions and Lennard-Jones (LJ) mixtures. The results' convergence and accuracy are convincing in all cases, thus emphasising the method's robustness and capabilities.

Abstract
BACKGROUND AND OBJECTIVE Non-invasively predicting the risk of cancer metastasis before surgery can play an essential role in determining which patients can benefit from neoadjuvant chemotherapy. This study aims to investigate and test the advantages of applying a random projection algorithm to develop and optimize a radiomics-based machine learning model to predict peritoneal metastasis in gastric cancer patients using a small and imbalanced computed tomography (CT) image dataset. METHODS A retrospective dataset involving CT images acquired from 159 patients is assembled, including 121 and 38 cases with and without peritoneal metastasis, respectively. A computer-aided detection scheme is first applied to segment primary gastric tumor volumes and initially compute 315 image features. Then, five gradients boosting machine (GBM) models embedded with five feature selection methods (including random projection algorithm, principal component analysis, least absolute shrinkage, and selection operator, maximum relevance and minimum redundancy, and recursive feature elimination) along with a synthetic minority oversampling technique, are built to predict the risk of peritoneal metastasis. All GBM models are trained and tested using a leave-one-case-out cross-validation method. RESULTS Results show that the GBM model embedded with a random projection algorithm yields a significantly higher prediction accuracy (71.2%) than the other four GBM models (p<0.05). The precision, sensitivity, and specificity of this optimal GBM model are 65.78%, 43.10%, and 87.12%, respectively. CONCLUSIONS This study demonstrates that CT images of the primary gastric tumors contain discriminatory information to predict the risk of peritoneal metastasis, and a random projection algorithm is a promising method to generate optimal feature vector, improving the performance of machine learning based prediction models.

Abstract
AbstractPreviously known as severe myoclonic epilepsy of infancy, Dravet syndrome is characterized by febrile or afebrile prolonged hemiconvulsive seizures or generalized status epilepticus in an infant with previously normal development. Immediate management of status epilepticus is critical in these patients. Early control of status epilepticus prevents further brain damage; however, there is no consensus regarding the management of status epilepticus in children with Dravet syndrome, as many conventional antiseizure medications that are recommended in the management of status epilepticus worsen the seizures in these patients. A 2.5-year-old girl child patient was referred due to status epilepticus which was refractory to antiseizure medications. Sodium valproate, nitrazepam, ketogenic diet, intravenous phenytoin, and midazolam continuous infusion were administered. After controlling status epilepticus, the probable diagnosis of Dravet syndrome was proposed and confirmed by a mutation in SCN1A. As previously stated in numerous case reports, phenytoin worsens seizures in patients with Dravet syndrome. Therefore, it seems logical that in every infant with status epilepticus and probable Dravet syndrome, the practicing physician considers administering intravenous valproate or even midazolam continuous infusion instead of intravenous phenytoin.

Abstract
Muscular dystrophy-dystroglycanopathies are autosomal recessive neurologic disorders, caused by homozygous or compound heterozygous mutations in the POMGNT1 gene-encoding protein O-mannose beta-1,2-N-acetylglucosaminyl transferase. This type of muscular dystrophy is characterized by early-onset muscle weakness, gait ataxia, microcephaly, and developmental delay.We performed whole-exome sequencing to detect the disease-causing variants in a 4 year-old boy. Afterwards, Sanger sequencing was performed to confirm the detected variant in the patient and his family. We evaluated a 4 year-old Iranian boy presented with delayed speech and language development, gait ataxia, global developmental delay, motor delay, neurodevelopmental delay, postnatal microcephaly and strabismus. His parents were first cousins, and the mother had a history of spontaneous abortion. In this study, we report a novel missense c.386G > A; p.(Arg129Gln) variant in the POMGNT1 gene which was confirmed by Sanger sequencing in the patient and segregated with the disease in the family.

Abstract
OBJECTIVE Since computer-aided diagnosis (CAD) schemes of medical images usually computes large number of image features, which creates a challenge of how to identify a small and optimal feature vector to build robust machine learning models, the objective of this study is to investigate feasibility of applying a random projection algorithm (RPA) to build an optimal feature vector from the initially CAD-generated large feature pool and improve performance of machine learning model. METHODS We assemble a retrospective dataset involving 1,487 cases of mammograms in which 644 cases have confirmed malignant mass lesions and 843 have benign lesions. A CAD scheme is first applied to segment mass regions and initially compute 181 features. Then, support vector machine (SVM) models embedded with several feature dimensionality reduction methods are built to predict likelihood of lesions being malignant. All SVM models are trained and tested using a leave-one-case-out cross-validation method. SVM generates a likelihood score of each segmented mass region depicting on one-view mammogram. By fusion of two scores of the same mass depicting on two-view mammograms, a case-based likelihood score is also evaluated. RESULTS Comparing with the principle component analyses, nonnegative matrix factorization, and Chi-squared methods, SVM embedded with RPA yielded a significantly higher case-based lesion classification performance with the area under ROC curve of 0.84 ± 0.01 (p<0.02). CONCLUSION The study demonstrates that RPA is a promising method to generate optimal feature vectors and improve SVM performance. SIGNIFICANCE This study presents a new method to develop CAD schemes with significantly higher and robust performance.

Abstract
OBJECTIVE This study aims to develop and test a new computer-aided diagnosis (CAD) scheme of chest X-ray images to detect coronavirus (COVID-19) infected pneumonia. METHOD CAD scheme first applies two image preprocessing steps to remove the majority of diaphragm regions, process the original image using a histogram equalization algorithm, and a bilateral low-pass filter. Then, the original image and two filtered images are used to form a pseudo color image. This image is fed into three input channels of a transfer learning-based convolutional neural network (CNN) model to classify chest X-ray images into 3 classes of COVID-19 infected pneumonia, other community-acquired no-COVID-19 infected pneumonia, and normal (non-pneumonia) cases. To build and test the CNN model, a publicly available dataset involving 8474 chest X-ray images is used, which includes 415, 5179 and 2,880 cases in three classes, respectively. Dataset is randomly divided into 3 subsets namely, training, validation, and testing with respect to the same frequency of cases in each class to train and test the CNN model. RESULTS The CNN-based CAD scheme yields an overall accuracy of 94.5 % (2404/2544) with a 95 % confidence interval of [0.93,0.96] in classifying 3 classes. CAD also yields 98.4 % sensitivity (124/126) and 98.0 % specificity (2371/2418) in classifying cases with and without COVID-19 infection. However, without using two preprocessing steps, CAD yields a lower classification accuracy of 88.0 % (2239/2544). CONCLUSION This study demonstrates that adding two image preprocessing steps and generating a pseudo color image plays an important role in developing a deep learning CAD scheme of chest X-ray images to improve accuracy in detecting COVID-19 infected pneumonia.
