Abstract
PURPOSE/OBJECTIVE(S) Rectal dose can be significantly decreased after spacer application. An initially fluid spacer (FS) spreads in a predetermined space, whereas the positioning of a viscous spacer is determined by needle guidance. The aim of this study was to evaluate the application a radiopaque viscous spacer (RVS) for prostate cancer radiotherapy (RT). MATERIALS/METHODS In 30 patients including three centers, 10ml (median) of a RVS was injected between the prostate and anterior rectal wall. The resulting distance and distribution were determined in different planes and compared with a control group of 30 patients with a FS. A cone beam computed tomography (CBCT) was performed at least at the end of RT, a magnetic resonance imaging (MRI) 3 months and 12 months after RT. Injection and treatment tolerability were analyzed. RESULTS With a median prostate volume of 40cm3, no overlap was found between planning target volume and rectal volume in most cases (median = 0cm3, interquartile range, IQR 0-0.6cm3). The median contoured RVS before, at the end and 3 months after RT was 8.5cm3, 8.7cm3 und 6.4cm3. Signs of hydrogel migration were not found in any case. Hydrogel visibility in CBCT was rated with "4" on a scale between 1 (poor) and 5 (excellent). Small residues were detected in the MRI 12 months after RT in 3 cases (10%). The median distance between prostate and rectum at the base / midplane / apex was 14mm / 12mm / 11mm. The median rectal volume percentage within the 90% and 80% isodoses was 3.0% (IQR 1.5-4.5%) bzw. 5.9% (IQR 3.0-10.6%). On a scale between 1 (difficult) and 5 (very easy), ease of application was rated with "3-4". Procedure- or device related adverse events have not been observed in any case. Acute and late gastrointestinal toxicities were found in 17% and 3%, respectively (all grade 1). The control of gel distribution of RVS relative to FS was rated with "3-5" on a scale between 1 (much worse) and 5 (much better), the ease of application relative to FS with "2-3" on a scale between 1 (much harder) and 5 (much easier). With a median contoured FS volume of 9.9cm3, the prostate-rectum distance at the base / midplane / apex was 12mm / 10mm / 10mm (significantly smaller in comparison to RVS). However, the lateral gel extension of RVS was smaller in all planes, statistically significant for all comparisons (base: 28mm vs. 34mm, midplane: 28mm vs. 32mm, apex: 21mm vs. 26mm). The gel symmetry (right vs. left) was comparable. CONCLUSION The application of a radiopaque viscous hydrogel spacer is harder in comparison to the initially fluid spacer. However, it can be better controlled and is achievable without any complications. Visibility in CBCT is good. The resulting prostate-rectum distance is >10mm in most cases and slightly larger at the base in comparison to FS. The resulting rectum volume within the high dose region and radiotherapy toxicity are very low.

Abstract
Background and Aim MicroRNAs (miRNAs) play an important role in various biological functions. According to many studies, miRNA expression is tissue-specific, strongly controlled throughout embryogenesis, and over- or under-expressed in numerous disorders, including cardiovascular pathologies. This study aimed to screen, characterize, and profile many induced biomarkers (miRNAs) in dog serum before and after experimentally inducing a regional myocardial infarction (MI) by occluding the coronary arteries under general anesthesia. Materials and Methods A preclinical experimental animal study recruited 12 healthy canine dogs. The selected canine dogs were anesthetized with 1 mg/kg xylazine and 15 mg/kg ketamine before undergoing femoral arterial catheterization under fluoroscopic supervision. Commercial assay kits were used to purify total RNA and miRNA before the occlusion and 2 h after the occlusion according to the manufacturer's guidelines, and the samples were stored in RNase/DNase-free water at -80°C. Data were analyzed by GraphPad Prism 5.0 software (GraphPad Prism, San Diego, CA) SPSS, and GenEx software (www.multid.se) or (REST V3). Results Among 325 transcribed genes, 20 were identified in 2 h. After MI, 14 biomarkers were negative, indicating downregulation, and 6 (3-F08, 3-B10, 4-A11, 1-A06, 2-E01, 3-F10) were positive, indicating upregulation. Polymerase chain reaction assay results showed a normalized fold-change in gene expression in the test sample. Fold values >1 represented a biologically significant change. Conclusion Profiling of miRNAs before and after MI in a dog model revealed upregulation of six previously unidentified biomarkers (3-F08, 3-B10, 4-A11, 1-A06, 2-E01, and 3-F10), indicating various miRNA regulatory patterns.

Abstract
The world health organization has announced that SARS-CoV-2 Omicron variant (B.1.1.529), including the three versions; 21K (BA.1), 21L (BA.2) and 21M (BA.3) as a variant of concern (VOC) on November 2022. In this study, we used the specialized computational platforms to predict the stability and flexibility of the spike protein of Omicron. The aim of this study was to investigate the expected effect of Omicron spike mutations on its physiochemical properties. Findings of this study revealed 16 stabilizing mutations that might explain a newly gained environmental stability. We expect the new mutations to play a crucial role in changing the physiochemical properties of epitopes of the spike protein. The notable finding of SuerPose work was the potential linear B-cells epitope G252 → S255 that has been changed in the spike protein of the Omicron 21L to a helix structure which might confer an escape from human monoclonal antibodies.

Abstract
The spike protein of SARS-CoV-2 plays a crucial role in binding with the human cell surface, which causes its pathogenicity. This study aimed to predict molecular dynamics change of emerging variants in the spike protein. In this study, several structural biology tools, such as SuperPose, were utilized to study spike protein structures' thermodynamics, superimposition, and the spike protein disulphide bonds. This questions the current vaccines efficacies that were based on the Nextstrain clade 19A that first documented in Wuhan and lacks any variants. The prediction results of this study have exhibited the stabilizing role of the globally dominant variant, the D614G; clade 20A, and other variants in addition to their role in increasing the flexibility of the spike protein of the virus. The SuperPose findings have revealed a conformational change impact of D614G in allowing the polybasic Furin cleavage site (682RRAR↓S686) to be closer to the receptor-binding domain (RBD) and hence more exposed to cleavage. The presence of D614G in any clade or subclade, such as 20A, B.1.1.7 (20I/501Y.V1) or Alpha, B.1.351 (20H/501Y.V2) or Beta, P.1 (20J/501Y.V3) or Gamma, B.1.617.2 (21A/478K.V1) or Delta, has increased its stability and flexibility and unified the superimposition among all clades which might impact the virus ability to escape the antibodies neutralization by changing the antigenicity drift of the protein three-dimensional (3D) structure from the wild type clade 19A; this is in agreement with previous study. In conclusion, a new design for the current vaccines to include at least the mutation D614G is immediately needed.

Abstract
Purpose Ischemic stroke of the brain is still considered one of the most common causes of disability and death in developed and developing countries in human beings despite advances in medicine and technology. This study was conducted to characterize and profile tens of induced biomarkers (microRNAs) after experimentally inducing regional ischemic stroke of the brain by occluding the middle cerebral artery under fluoroscopic guidance using an autologous blood clot. Patient and Methods A total of six healthy dogs were recruited for this study. The microRNAs were profiled in the blood and urine before and after occluding the middle cerebral artery using genetic techniques. Results The very highly expressed genes were comprised within cluster A, followed by cluster D in both 24 and 48-hour brain samples. Clusters B and C revealed down-regulated genes, while miRNAs remained up-regulated in the 24-hour samples merely in cluster F. Upregulated genes at 48 hours of reperfusion were included in cluster E. On the other hand, changes were observed after a day on the cluster G genes. Exclusive upregulation was notified after 2 days due to the changes in mIR-138. The normalized gene expression in the test sample is witnessed through Fold-Change, which divides the control sample’s normalized gene expression. Moreover, fold-change has emerged as a significant approach for representing fold-regulation. Conclusion The microRNAs expression in blood and urine may have a potential role in the diagnosis, prognosis, and assessment of therapy associated with cerebral artery occlusion under fluoroscopic guidance.

Abstract
MicroRNAs (miRNAs) are non-coding RNAs that control many functions within the human cells by controlling protein levels through binding to messenger RNA (mRNA) translation process or mRNA abundance. Many pieces of evidence show that miRNAs affect the viral RNA replication and pathogenesis through direct binding to the RNA virus to mediate changes in the host transcriptome. Many previous studies have been studying the interaction between human cells' miRNA and viral RNA to predict many targets along the viral genome. In this work, via the miRDB database, we determined the target scores of predicted human miRNA to bind with the ss-RNA of the severe acute respiratory syndrome coronavirus (SARS-CoV-2) in general and its spike gene in specific. Our predicted miRNA targets of the ss-RNA of SARS-CoV-2 might destabilize the ss-RNA translation of SARS-CoV-2 that has been established by more than 80% of asymptomatic infected cases in Jordan due to host miRNA interactions. In respiratory epithelial cells, the high prediction scoring for miRNAs covers the RNA from 5' to 3' that explains successful antiviral defenses against ss-RNA of SARS-CoV-2 and might lead to new nucleotide deletion mechanisms. The exciting findings here that the nucleotide substitution 1841A > G at the viral genomic RNA level, which is an amino acid substation D614G at the spike protein level showed a change in the predicted miRNA sequence from hsa-miR-4793-5p to hsa-miR-3620-3p with an increase in the target score from 91 to 92.

Abstract
Introduction
There are cardiovascular morbid effects of OSA in adults and children. We have previously reported over-expression of Nuclear-Factor-κappa B in tonsils of children with OSA, and NF-κB activation after exposure to sera of children with OSA. In order to investigate NF-kB activation and the physiology of cardiomyocytes of human origin (CM’s), we have established an ex-vivo model where CM’s derived from human embryonic stem cells H-9.1 clone (hES) and from Induced pluripotent stem cells (iPSC) are either incubated with human sera, or exposed to intermittent hypoxia(IH) or room air (RA).
Methods
Serum samples were drawn following overnight polysomnography (PSG) from children with OSA (AHI>5) or control (AHI<1). Differentiated human cardiomyocytes were incubated with 5% OSA sera or control. Average cell beating/min was determined and NF-kB p50 and p65 cytoplasmic or nuclear localization were detected by immunofluorescence (operetta). CM’s were exposed to either RA or to IH (21% alternating with 1% O2, 6 cycles/h, 24 h) in a chamber (BioSpherix Instruments, Redfield, NY)Intracellular calcium transient signal (ionoptix) and mechanical contraction of CM (Musclemotion) were assessed.
Results
1. Cell beating/min was reduced in cells incubated with OSA (n=10) as compared to control (n=10);(p<0.01), and following IH exposure vs RA (p<0.01),). 2. There is an over-expression of NF-κB p50, p65 subunits as a result of exposing CMs to OSA sera, and following IH exposure 3. a rapid decrease (up to 100%) was measured in calcium transient amplitude as well as contraction amplitude (p<0.05) after adding OSA sera, that was completely restored after washing.
Conclusion
We revealed human cardiomyocytes NF-kB activation and decreased contractility following exposure to OSA sera and to IH. The rapid decrease in calcium signaling and contractility infer the presence of factors that reversibly affects CMs contraction. This ex-vivo model enables the study of functional and molecular alterations in human CM

Abstract
Acid sphingomyelinase (ASM) deficiency (ASMD) is a spectrum that includes Niemann-Pick disease (NPD) types A (NPD A) and B (NPD B). ASMD is characterized by intracellular accumulation of unesterified cholesterol and gangliosides within the endosomal-lysosomal system. It is caused by different mutations in SMPD1 gene that result in reduction or complete absence of acid sphingomyelinase activity in the cells. Herein, four unrelated consanguineous families with two NPD A and three NPD B patients were assessed for their genotypes via sequencing of the SMPD1 gene and their acid sphingomyelinase enzymatic activity. Among the eight identified mutations, three were novel and reported for the first time in Jordanian families (c.120_131delGCTGGCGCTGGC or c.132_143delGCTGGCGCTGGC, c.1758T > G, and c.1344T > A). All the patients displayed ASM activity lower than 1.3 µmol/l/h (P < 0.001). Genotyping and enzymatic assessment might play a significant role in disease identification in people at risk to facilitate genetic counseling in the future.

Abstract
OBJECTIVE The main objectives of this study are to investigate the prevalence of HCV among patients with β-thalassemia major and to determine the most prevalent genotype for this virus among them. METHODS One hundred twenty-two β-thalassemia major patients who were previously diagnosed at the molecular level were included. All plasma samples were tested for the presence of antibodies by ELISA. Real-time polymerase chain reaction (PCR) was used in the quantitation the HCV RNA viral loads, and consequently, patients with high virus titer were genotyped by the linear array. RESULTS Forty of the patients were anti-HCV positive. The prevalence of anti-HCV was significantly higher in patients who received blood transfusion before 1993 (83.7%) than in those who received it after 1993 (16.3%) (p=0.000). β-thalassemia major patients with HCV infection had significantly higher rates of elevated aspartate aminotransferase (54.4% vs 40.5%, p=0.045) and alanine aminotransferase (72.47% vs 37.47%, p=0.00) and of splenectomy (54.8% vs 45.2%, p=0.004) than β-thalassemia major patients without HCV. CONCLUSION HCV genotype 4 is the commonest genotype in multi-transfused patients with β-thalassemia major in Jordan.

Abstract
Gorham-Stout disease or the so-called vanishing bone syndrome is a rare disorder characterized by intra-osseous proliferation of vascular channels resulting in destruction and resorption of the osseous matrix. The exact pathology of this disease showed no evidence of malignant, neuropathic, or infectious components involved in the causation of this disorder except for the culprit of lympho-vascular malformations in the bone. The mechanism of bone resorption is yet to be clarified. The clinical presentation of Gorham's disease varies according to the organ of involvement. Patients diagnosed with Gorham's disease in the bone may initially present with insidious onset of dull aching pain, progressive weakness, or pathologic fractures as the initial presentation. Gorham's disease is progressive in most patients; yet it can be self-limiting in a few reported cases. The axes of treating this disease as reported in the literature include the use of medical treatment, surgical intervention, radiotherapy and/or the combination of any them. However, there is no consensus about the most effective approach for treating this rare disease. The challenge in this disease lies in both: how to diagnose and how to treat. Our novel approach combined surgical intervention, medication and radiotherapy as a treatment of Graham-Stout disease in the humerus, and showed no progression of the disease our case.

Abstract
Electrical storm refers to a state of cardiac electrical instability characterized by multiple episodes of ventricular tachycardia (VT) or ventricular fibrillation (VF) within a relatively short period of time and is associated with increased mortality and morbidity. The management of electrical storm involves a variety of strategies, including sedation, anti-arrhythmic and electrolyte replacement as well as revascularization and electrical ablation. However, the management strategy in patients with refractory storm is less clear and may require more invasive approaches. We present a case of severe ventricular tachycardia storm refractory to conservative management that was managed with a HeartMate II left ventricular assist device.

Abstract
BACKGROUND The body of knowledge regarding the different facets of frostbite injury continues to expand. However, beside the administration of physiological saline, local rewarming, local disinfection and symptomatic medications, today no causal therapy is known which would accelerate angiogenesis and wound healing. The aim of this study was to investigate the influences of dilative acting drugs on microcirculation, angiogenesis and leukocyte behavior. MATERIALS AND METHODS Ears of male hairless mice (n=40) were inflicted with full thickness frostbites using a cold air jet. Then the affects of four intraperitoneal injections of isosorbitdinitrate (ISDN, n=10), l-nitroarginine-methyl-ester (l-NAME, n=10), selenium (n=10) or sodium chloride (n=10; each administered to one of four corresponding study groups), on microcirculation, leukocyte-endothelial interaction and angiogenesis were investigated over a 12-day period using intravital fluorescent microscopy. RESULTS Angiogenesis was most improved by ISDN (36.8 vs. 54.5% non-perfused area on day 3, 3.9 vs. 17.0% on day 7 compared to selenium, p<0.006). Venular diameter was most significantly dilated in the ISDN-group, l-NAME showed significantly decreased diameter over the complete time of 12 days. ISDN had positive influences on edema formation, which was significantly reduced compared to control (27% lower values compared to control; p=0.007 on day 3). The l-NAME-group showed the significant highest leukocyte-adhesion compared to control on days 7 and 12 (53% resp. 58% higher, p<0.006). CONCLUSION Overall, out of all the drugs tested, ISDN improved angiogenesis, dilated venules and decreased edema formation and therefore seems to have the greatest positive impact on these crucial parameters after frostbite injury.

Abstract
PURPOSE To assess high-risk human papillomavirus (HR-HPV) prevalence, and genotype distribution in invasive cervical cancer (CC) and its precursors in Jordanian patients. MATERIALS AND METHODS A total of 124 different specimens of formalin-fixed, paraffin embedded samples, including 18 low-grade squamous intraepithelial lesions (LSILs), 28 high grade squamous intraepithelial lesions (HSILs), and 78 CCs were included in this study. HPV detection and typing was done using HPV High Risk Typing Real-TM Kit that enables the concomitant detection of the 12 most common HR-HPVs. RESULTS Overall, HR-HPV prevalence was 87.2%, 78.6%, and 72.2% in CC, HSIL, and LSIL respectively. Genotype 16 was the most predominant in all cervical lesions, detected in 53.8%, 46.4%, and 38.9% of CC, HSIL, and LSIL, respectively. Among all HPV genotypes, HPV-16 and HPV-18 were found separately or together in 50% of LSILs, 60.7% of HSILs, and 76.9% of CC specimens. HPV-31 was the second most common type detected in LSILs (22.2%) and HSILs (21.4%). HPV-45 was the third most common type detected in CC (11.5%). CONCLUSION The prevalence and genotypes distribution patterns of HR-HPV types among patients with CC and its precursors in Jordan are similar to known international patterns. The results of this study provide baseline information on the HPV type distribution, which may guide the development of CC prevention and control programs in Jordan.

Abstract
Concepts of disease severity, activity, control and responsiveness to treatment are linked but different. Severity refers to the loss of function of the organs induced by the disease process or to the occurrence of severe acute exacerbations. Severity may vary over time and needs regular follow-up. Control is the degree to which therapy goals are currently met. These concepts have evolved over time for asthma in guidelines, task forces or consensus meetings. The aim of this paper is to generalize the approach of the uniform definition of severe asthma presented to WHO for chronic allergic and associated diseases (rhinitis, chronic rhinosinusitis, chronic urticaria and atopic dermatitis) in order to have a uniform definition of severity, control and risk, usable in most situations. It is based on the appropriate diagnosis, availability and accessibility of treatments, treatment responsiveness and associated factors such as comorbidities and risk factors. This uniform definition will allow a better definition of the phenotypes of severe allergic (and related) diseases for clinical practice, research (including epidemiology), public health purposes, education and the discovery of novel therapies.

Abstract
Résumé
Introduction
Le cancer du sein, première pathologie maligne chez la femme, reste une maladie rare chez l’homme. Il représente environ 1 % des cancers du sein et moins de 1 % de l’ensemble des néoplasies masculines. L’objectif de cette étude est d’analyser les caractéristiques cliniques, histologiques et thérapeutiques du cancer du sein chez l’homme.
Patients et méthodes
Les auteurs présentent une étude descriptive menée de manière rétrospective au service de radiothérapie-oncologie du CHU Ibn-Rochd de Casablanca, entre janvier 2006 et décembre 2007, concernant une série de 21 patients de sexe masculin présentant un cancer du sein.
Résultats
L’âge médian était de 70 ans (extrêmes: 39–84). Le délai médian de consultation était de huit mois (extrêmes: 2–24). Il s’agissait, dans 16 cas, d’une tumeur rétroaréolaire dont la taille médiane était de 35 mm (extrêmes: 15–80). Les tumeurs étaient classées T2 dans 12 cas et T4 dans sept cas. Le type histologique le plus représenté était le carcinome canalaire infiltrant (CCI) [18 cas]. Le grade SBR II a été retrouvé dans 13 cas. Le taux d’envahissement ganglionnaire axillaire prouvé histologiquement était de 38 % (huit patients) et dans 14 % des cas plus de trois ganglions étaient envahis. L’effraction capsulaire n’a été retrouvée que dans quatre cas. Les récepteurs hormonaux étaient positifs dans 19 cas. La prise en charge thérapeutique a consisté en une chirurgie radicale dans 14 cas avec une chimiothérapie associée à une radiothérapie dans cinq cas, 66 % des patients ont reçu une hormonothérapie. Après un suivi moyen de 23 mois, trois malades ont développé des métastases et six malades sont encore vivants sans maladie.
Conclusion
Le cancer du sein chez l’homme est rare. Son diagnostic se fait souvent à un stade tardif. Son traitement est similaire à celui de la femme avec un retard diagnostique retentissant sur le pronostic.

Abstract
AIM Adequate lymph node resection in rectal cancer is important for staging and local control. This study aims to verify the effect of neoadjuvant chemoradiation, as well as some clinicopathological features, on the yield of lymph nodes in rectal carcinoma. METHODS Data on consecutive patients who had total mesorectal excision for rectal adenocarcinoma at a single cancer center between January 2003 and July 2008 were reviewed. No patient had any prior pelvic surgery or radiotherapy. Patients had neoadjuvant chemoradiotherapy if they were stage II or III. RESULTS A total of 116 patients were included. The mean age was 53 years (range 29-83). Fifty-nine patients (51%) received neoadjuvant therapy before resection. The mean number of lymph nodes removed was 18 (range 4-67) per specimen. There was less lymph node yield in patients who received neoadjuvant therapy (16 vs. 19, p = 0.008). Only 64% of patients who had preoperative therapy had 12 lymph nodes or more in the specimen as opposed to 88% of those who had surgery upfront (p = 0.003). Other factors associated with lower lymph node yield included: female sex (p = 0.03) and tumour location in the lower rectum (p = 0.002). Age, tumour stage and grade, type of operation and surgical delay did not affect the number of lymph nodes removed. CONCLUSION Preoperative chemoradiotherapy for rectal cancer results in reduction in lymph node yield. Female sex and lower rectal tumours are also associated with retrieval of fewer lymph nodes.

Abstract
Neuroendocrine carcinoma with large cells is a slightly different tumor from the high rank of malignity. We report a case of breast localization in a 28-year-old patient. It is a locally advanced classified T4dN1M0 tumor that required neoadjuvant chemotherapy. The clinical answer was 75% of the level of the tumor. A standard surgery mastectomy with axillary lymph node dissection was realized, followed by external radiotherapy. The anatomopathologic and the immuno-histochemical study of the operational part confirmed the diagnosis of neuroendocrine carcinoma with large cells expressing the progesterone receptor. The patient is subjected to adjuvant hormonal treatment. After a 12 months retreat, a complete remission is maintained. Considering the scarcity of neuroendocrine carcinoma with large cells of the breast, the therapeutic standard is not yet available and the forecast remains difficult to determine.

Abstract
BACKGROUND Infants born to diabetic women are at higher risk for hypoglycaemia related to hyperinsulinism in response to maternal hyperglycaemia during pregnancy. As such, recommendations to prevent neonatal hypoglycaemia include infant feeding in the early postpartum period. The present study aimed to examine the effect of early breastfeeding and type of nutrition used for the first feed (human milk or formula) on glucose levels in infants born to women with gestational diabetes. METHODS The prospective pilot study of 84 infants born to gestational diabetic women examined the glycaemic levels of infants who were breastfed in the delivery room compared to glycaemic levels of those who were not. The study also compared the glycaemic levels of infants who breastfed with those who received formula for their first feed. RESULTS Infants who were breastfed in the delivery room had a significantly lower rate of borderline hypoglycaemia than those who were not breastfed in the early postpartum period (10% versus 28%; Fisher's exact test., P = 0.05,). Likewise, infants breastfed in the delivery room had significantly higher mean blood glucose level compared to infants who were not breastfed in the delivery room (3.17 versus 2.86 mmol L(-1), P = 0.03). Additionally, breastfed infants had a significantly higher mean blood glucose level compared to those who were formula fed for their first feed (3.20 versus 2.68 mmol L(-1), P = 0.002). CONCLUSIONS Early breastfeeding may facilitate glycaemic stability in infants born to women with gestational diabetes.
