Abstract
Glioblastoma (GBM) represents a profoundly aggressive and heterogeneous brain neoplasm linked to a bleak prognosis. Hypoxia, a common feature in GBM, has been linked to tumor progression and therapy resistance. In this study, we aimed to identify hypoxia-related differentially expressed genes (DEGs) and construct a prognostic signature for GBM patients using multi-omics analysis. Patient cohorts were collected from publicly available databases, including the Gene Expression Omnibus (GEO), the Chinese Glioma Genome Atlas (CGGA), and The Cancer Genome Atlas-Glioblastoma Multiforme (TCGA-GBM), to facilitate a comprehensive analysis. Hypoxia-related genes (HRGs) were obtained from the Molecular Signatures Database (MSigDB). Differential expression analysis revealed 41 hypoxia-related DEGs in GBM patients. A consensus clustering approach, utilizing these DEGs' expression patterns, identified four distinct clusters, with cluster 1 showing significantly better overall survival. Machine learning techniques, including univariate Cox regression and LASSO regression, delineated a prognostic signature comprising six genes (ANXA1, CALD1, CP, IGFBP2, IGFBP5, and LOX). Multivariate Cox regression analysis substantiated the prognostic significance of a set of three optimal signature genes (CP, IGFBP2, and LOX). Using the hypoxia-related prognostic signature, patients were classified into high- and low-risk categories. Survival analysis demonstrated that the high-risk group exhibited inferior overall survival rates in comparison to the low-risk group. The prognostic signature showed good predictive performance, as indicated by the area under the curve (AUC) values for one-, three-, and five-year overall survival. Furthermore, functional enrichment analysis of the DEGs identified biological processes and pathways associated with hypoxia, providing insights into the underlying mechanisms of GBM. Delving into the tumor immune microenvironment, our analysis revealed correlations relating the hypoxia-related prognostic signature to the infiltration of immune cells in GBM. Overall, our study highlights the potential of a hypoxia-related prognostic signature as a valuable resource for forecasting the survival outcome of GBM patients. The multi-omics approach integrating bulk sequencing, single-cell analysis, and immune microenvironment assessment enhances our understanding of the intricate biology characterizing GBM, thereby potentially informing the tailored design of therapeutic interventions.

Abstract
BACKGROUND Primary focal hyperhidrosis (PH) can be managed by a wide range of medical and surgical modalities. Compensatory hyperhidrosis (CH) is a well-documented complication of surgical treatment. We aimed to investigate the occurrence of compensatory hyperhidrosis (CH) in PH patients after nonsurgical treatment with botulinum toxin A (BTX- A) or iontophoresis. METHODOLOGY We carried out a unicentric prospective study on PH patients from King Abdullah University Hospital (KAUH) in Jordan. PH patients were evaluated after 1-month of nonsurgical treatment. Patients who developed CH were re-assessed after 3-6 months through a telephone-based interview. RESULTS A total of 86 patients with PH who underwent nonsurgical treatment with iontophoresis or botulinum toxin were recruited. Twenty-four (27.9%) patients developed subjective CH. It was mild in (75%), moderate in (21%), and severe in (4%) of patients affected, it was self-limiting within a few months in all patients. Patients with CH did not differ significantly in demographic or clinical variables from patients who did not develop CH except at the site of PH (p value = .05). CONCLUSION The findings of this study indicate that more than quarter (27.9%) of patients with PH may develop minor compensatory sweating, however this didn't affect satisfaction with treatment.

Abstract
Purpose The study aimed to create a machine learning model (MLM) to predict the stone-free status (SFS) of patients undergoing percutaneous nephrolithotomy (PCNL) and compare its performance to the S.T.O.N.E. and Guy's stone scores. Patients and Methods This is a retrospective study that included 320 PCNL patients. Pre-operative and post-operative variables were extracted and entered into three MLMs: RFC, SVM, and XGBoost. The methods used to assess the performance of each were mean bootstrap estimate, 10-fold cross-validation, classification report, and AUC. Each model was externally validated and evaluated by mean bootstrap estimate with CI, classification report, and AUC. Results Out of the 320 patients who underwent PCNL, the SFS was found to be 69.4%. The RFC mean bootstrap estimate was 0.75 and 95% CI: [0.65-0.85], 10-fold cross-validation of 0.744, an accuracy of 0.74, and AUC of 0.761. The XGBoost results were 0.74 [0.63-0.85], 0.759, 0.72, and 0.769, respectively. The SVM results were 0.70 [0.60-0.79], 0.725, 0.74, and 0.751, respectively. The AUC of Guy's stone score and the S.T.O.N.E. score were 0.666 and 0.71, respectively. The RFC external validation set had a mean bootstrap estimate of 0.87 and 95% CI: [0.81-0.92], an accuracy of 0.70, and an AUC of 0.795, While the XGBoost results were 0.84 [0.78-0.91], 0.74, and 0.84, respectively. The SVM results were 0.86 [0.80-0.91], 0.79, and 0.858, respectively. Conclusion MLMs can be used with high accuracy in predicting SFS for patients undergoing PCNL. MLMs we utilized predicted the SFS with AUCs superior to those of GSS and S.T.O.N.E scores.

Abstract
Royal jelly (RJ) is a multifunctional bee product with a unique composition and wide-ranging biological properties, including antioxidant, anti-inflammatory and antiproliferative activities. Still, little is known about the possible myocardial protective properties of RJ. Considering that sonication could enhance RJ bioactivity, this study aimed to assess the effects of non-sonicated (NS) and sonicated (S) RJ on fibrotic signaling, cell proliferation, and collagen production in cardiac fibroblasts. S-RJ was produced by ultrasonication at 20 kHz. Ventricular fibroblasts isolated from neonatal rats were cultured and treated with different concentrations of NS-RJ or S-RJ (0, 50, 100, 150, 200, and 250 µg/well). S-RJ significantly depressed the expression levels of transglutaminase 2 (TG2) mRNA across all the concentrations tested and was inversely associated with the expression of this profibrotic marker. S-RJ and NS-RJ displayed distinct dose-dependent effects on mRNA expression of several other profibrotic, proliferation, and apoptotic markers. Unlike NS-RJ, S-RJ elicited strong negative dose-dependent relationships with the expression of profibrotic markers (TG2, COL1A1, COL3A1, FN1, CTGF, MMP-2, α-SMA, TGF-β1, CX43, periostin), as well as proliferation (CCND1) and apoptotic (BAX, BAX/BCL-2) markers, indicating that RJ dose-response effects were significantly modified by sonification. NS-RJ and S-RJ increased the content of soluble collagen, while decreasing collagen cross-linking. Collectively, these findings show that S-RJ has a greater range of action than NS-RJ for downregulating the expression of biomarkers associated with cardiac fibrosis. Reduced biomarker expression and collagen cross-linkages upon cardiac fibroblast treatment with specific concentrations of S-RJ or NS-RJ suggests putative roles and mechanisms by which RJ may confer some protection against cardiac fibrosis.

Abstract
Abstract
Background: Glioblastoma multiforme (GBM) is the most common tumor of the central nervous system with poor prognosis. Cuproptosis is a novel programmed cell death pathway targeting lipoylated tricarboxylic acid cycle proteins. Previous studies have found that it participates in tumor progression, but its role in GBM is still elusive. In this study, we aimed to develop a cuproptosis gene-signature risk score using bioinformatics analysis and machine learning.
Methods: We acquired transcriptomic and clinical information of GBM patients from The Cancer Genome Atlas (TCGA). A total of 2283 differentially expressed genes (DEGs) were obtained from the GEPIA2 database. 26 cuproptosis-related genes (CRGs) were retrieved from literature. A correlation analysis between the 26 CRGs and the DEGs were conducted to retrieve the cuproptosis-related DEGs. Then, a univariate cox analysis was conducted to obtain the prognostic-related DEGs for overall survival (OS). The least absolute shrinkage and selection operator (LASSO) were conducted for regularization and the gene risk score was constructed using the multivariate cox coefficients.
Results: A total of 731 downregulated DEGs were correlated with CRGs, while 68 upregulated DEGs were correlated with CRGs and were further screened for prognostic value using the univariate cox analysis. A total of 70 prognostic related CRGs were identified and were further screened using the LASSO cox analysis. After multivariate cox analysis, a total of seven genes were significantly associated with survival (p-value<0.01). A risk-score gene signature was constructed from the cox coefficients multiplied by the expression of the following genes: -0.0012*DPP10+0.0021*EGR4+0.0015*ITPKA+ 0.0003* PTPRN+ 0.0007* STEAP2+ 0.0006* TENM2+- 0.0017* ZNF540.
Conclusion: Univariate and multivariate Cox regression analyses showed the CRGs-based prognostic signature independently functioned as a risk factor for OS in GBM patients. Furthermore, our results gave a promising understanding of cuproptosis in GBM, as well as a tailored prediction tool for prognosis and immunotherapeutic responses in patients.

Abstract
Immune checkpoint inhibitors (ICIs) became one of the most revolutionary cancer treatments, especially in melanoma. While they have been proven to prolong survival with lesser side effects compared to chemotherapy, the accurate prediction of response remains to be an unmet gap. Thus, we aim to identify accurate clinical and transcriptomic biomarkers for ICI response in melanoma. We also provide mechanistic insight into how high-performing markers impose their effect on the tumor microenvironment (TME). Clinical and transcriptomic data were retrieved from melanoma studies administering ICIs from cBioportal and GEO databases. Four machine learning models were developed using random-forest classification (RFC) entailing clinical and genomic features (RFC7), differentially expressed genes (DEGs, RFC-Seq), survival-related DEGs (RFC-Surv) and a combination model. The xCELL algorithm was used to investigate the TME. A total of 212 ICI-treated melanoma patients were identified. All models achieved a high area under the curve (AUC) and bootstrap estimate (RFC7: 0.71, 0.74; RFC-Seq: 0.87, 0.75; RFC-Surv: 0.76, 0.76, respectively). Tumor mutation burden, GSTA3, and VNN2 were the highest contributing features. Tumor infiltration analyses revealed a direct correlation between upregulated genes and CD8+, CD4+ T cells, and B cells and inversely correlated with myeloid-derived suppressor cells. Our findings confirmed the accuracy of several genomic, clinical, and transcriptomic-based RFC models, that could further support the use of TMB in predicting response to ICIs. Novel genes (GSTA3 and VNN2) were identified through RFC-seq and RFC-surv models that could serve as genomic biomarkers after robust validation.

Abstract
BACKGROUND Migraine is a primary headache disorder that causes debilitating throbbing pain. Several functional MRI (fMRI) and voxel-based morphometry (VBM) studies have been used to investigate the structural and functional alteration in migraine. Here, we aim to study the converged brain regions of functional and structural abnormalities in gray matter volume (GMV) associated with pain processing and management in migraineurs and healthy controls (HC). METHODS A systematic search through PubMed and Sleuth was carried out for peer-reviewed functional and structural neuroimaging studies on migraine patients and HC yielded a total of 1136 studies. We performed an activation likelihood estimation (ALE) meta-analysis on VBM and pain stimulation task-based fMRI studies to investigate the converged areas of GMV and functional abnormalities between migraineurs and HC. We performed two subgroup analyses between migraine with aura (MwA) and migraine without aura (MwoA) relative to HC, and between chronic migraine (CM) and episodic migraine (EM) compared to HC. RESULTS The total sample included 16 fMRI and 22 VBM studies, consisting of 1295 migraine patients, compared to 995 HC. In fMRI analysis, ALE maps for pain stimulation tasks revealed hyperactivation in migraineurs in the substantia nigra compared to HC, whereas hypoactivation was seen in the cerebellum. For the VBM analysis, ALE clusters of increased GMV in migraineurs were observed in the parahippocampus and putamen nucleus. Whereas clusters of reduced GMV in migraineurs were seen in the frontal gyri. Compared to HC, MwoA patients showed a GMV reduction in the insula, and anterior cingulate, whereas MwA patients showed GMV reduction in the cerebellum, cingulate gyrus, and insula. CM patients showed decreased GMV in the precentral gyrus, whereas EM patients showed decreased GMV in the parahippocampus, and inferior frontal gyrus when compared to HC. CONCLUSIONS Our findings represent a potential biomarker for the diagnosis and management of migraine, by showing clustered brain regions of abnormal patterns of activation and GMV changes between migraineurs and HC which might be associated with hyposensitivity to pain in migraineurs. Further studies are required to determine disease progression or therapeutic interventions' effect on migraine.

Abstract
We assessed whether stroke severity, functional outcome, and mortality in patients with ischemic stroke differed between patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and those without. We conducted a prospective, single-center cohort study in Irbid, North Jordan. All patients diagnosed with ischemic stroke and SARS-CoV-2 infection were consecutively recruited from October 15, 2020, to October 16, 2021. We recorded demographic data, vascular risk factors, National Institutes of Health Stroke Scale (NIHSS) score, stroke subtype according to the Trial of ORG 10172 in Acute Stroke Treatment Criteria (TOAST), treatments at admission, and laboratory variables for all patients. The primary endpoint was the functional outcome at 3 months assessed using the modified Rankin Score. Secondary outcomes involved in-hospital mortality and mortality at 3 months. We included 178 patients with a mean (standard deviation) age of 67.3 (12), and more than half of the cases were males (96/178; 53.9%). Thirty-six cases were coronavirus disease 2019 (COVID-19) related and had a mean (standard deviation) age of 70 (11.5). When compared with COVID-19-negative patients, COVID-19-positive patients were more likely to have a higher median NIHSS score at baseline (6 vs 11; P = .043), after 72 hours (6 vs 12; P = .006), and at discharge (4 vs 16; P < .001). They were also more likely to have a higher median modified Rankin Score after 3 months of follow-up (P < .001). NIHSS score at admission (odds ratio = 1.387, 95% confidence interval = 1.238-1.553]; P < .001) predicted having an unfavorable outcome after 3 months. On the other hand, having a concomitant SARS-CoV-2 infection did not significantly impact the likelihood of unfavorable outcomes (odds ratio = 1.098, 95% confidence interval = 0.270-4.473; P = .896). The finding conclude that SARS-CoV-2 infection led to an increase in both stroke severity and in-hospital mortality but had no significant impact on the likelihood of developing unfavorable outcomes.

Abstract
Background: As the incidence of intracranial infections increase due to diagnostic procedures improvement, more real-life data is needed to reach a more solid informed management approach. Objective: This study aims to describe and analyse clinical features of intracranial abscesses patients treated at a tertiary hospital in North Jordan during a 10-year period. Methods: We retrospectively identified 37 patients treated at King Abdullah University Hospital (KAUH) from 2011 to 2020 in Irbid, North Jordan. Treatment consisted of either aspiration, open craniotomy excision (OCE) or conservative therapy. Extracted variables included demographic data such (age, gender), clinical presentation, lab findings, radiological findings as well as management plan. Retrieved data was compared between the patients who underwent a single operation and those who underwent reoperation after the initial procedure. Results: Thirty-seven patients with 55 intracerebral abscesses were identified, 29 of whom had intraparenchymal brain abscesses, 4 patients had epidural empyema, and 4 had subdural empyema. The mean age was 28.8 (± 20.7) years, with a male predominance (78.4%). Sixteen patients underwent open craniotomy excision (OCE), 14 patients were treated by aspiration and 7 patients were treated conservatively. When comparing the single operation and the reoperation groups, there was no statistically significant difference across variables. Conclusion: Our study presents valuable insight from a tertiary hospital in north Jordan on intracranial abscesses and empyemas. Our findings confirm that good recovery can be established after aspiration or OCE in the majority of patients. Similar results were obtained when comparing the SOP and the ROP groups.

Abstract
BACKGROUND AND AIMS Conservative management of posterior fossa epidural hematoma in the pediatric age group has been increasingly considered in the last decade with good clinical outcomes and comparable results to surgical intervention in carefully selected patients. The purpose of this study is to evaluate the outcome of observation in the management of pediatric patients with posterior fossa epidural hematoma (PFEDH) in our tertiary hospital and present a literature review on PFEDH pediatric patients. METHODS We conducted a retrospective observational study at King Abdullah University Hospital (KAUH), a tertiary hospital in North Jordan. All pediatric patients (≤ 18 years) who were admitted with a diagnosis of PFEDH from January 2010 to December 2020 were included. Demographic data, trauma type, clinical signs and symptoms on admission, CT findings, treatment type, and outcomes were collected and assessed. The outcome was measured using the Glasgow outcome scale (GOS) on discharge from the hospital. RESULTS A total of 16 patients were identified and included in this study. Nine patients were managed conservatively and 7 surgically. The mean age was 7.7 ± 6 years ranging from 1 to 18 years. Falls were the most common cause of injury. Vomiting was the most frequent presenting symptom. Except for 1 patient, 14 patients had good outcomes with a GOS of 5. One case of mortality was seen in our series. CONCLUSION Posterior fossa epidural hematoma is a rare clinical condition among the pediatric age group. Early and consecutive CT scans must be obtained for all suspected cases. Successful conservative management can be achieved depending on multiple factors such as hematoma thickness or volume, neurological status on admission, and other radiological findings as shown in our study. The overall prognosis was good in our patients.

Abstract
BACKGROUND More than half of melanoma patients taking first-line anti-PD-1 therapy either express transient or no response at all. The efficacy and safety of secondary treatments for these patients are still not well established. Here, we evaluate the efficacy and safety of different melanoma FDA-approved ICI modalities used in post-anti-PD-1 refractory settings. MATERIALS AND METHODS We searched the PubMed database and the ASCO meetings library for studies on advanced melanoma patients with cancer progression on anti-PD-1 therapy and were then treated with ipilimumab, nivolumab/ipilimumab combination, or retreated with anti-PD-1. Primary and secondary endpoints were efficacy and toxicity, respectively. Pooled estimates for each treatment group were obtained using a random or fixed effects model according to detected heterogeneity. RESULTS Fourteen studies, of which 10 on ipilimumab, 2 on anti-PD-1 treatment, and 6 on combination therapies, were included, involving a total of 1460 patients. Twelve studies reported objective response rates (ORRs) and nine of them reported immune-related adverse events (irAEs). As for ORR, patients experienced a response that was inferior compared to the same therapy in treatment -naïve patients, with combination therapy having the best ORR of a pooled 23.08% (95% CI: 16.75% to 30.03%), followed by ipilimumab with a pooled ORR of 8.19% (95% CI: 5.78% to 10.92%). Survival data were also inferior in the ipilimumab cohort (mOS: 5.1 to 7.4 months) compared to ipilimumab in anti-PD-1 naive patients. As for grade 3/4 irAE occurrence, the ipilimumab cohort showed an estimate of 43.77% (95% CI 22.55% to 66.19%). CONCLUSION Our findings provide the best current evidence that patients who progress on anti-PD-1 can still respond to different ICI modalities (ipilimumab with or without nivolumab, and retreatment or continuation beyond progression with anti-PD-1) with tolerable grade 3/4 irAEs. However, more prospective clinical trials are needed to confirm these results.

Abstract
AIM To determine if there are correlations between the physical fitness of young soccer players assessed by field and laboratory testing. METHODS Thirty four male soccer players took part in the study (mean (SD) age 17.5 (1.1) years, height 177.8 (6.7) cm, weight 70.5 (6.4) kg). Maximal oxygen uptake (VO(2)MAX) during treadmill running and vertical jump height on a force platform were measured in the laboratory. Field tests consisted of a soccer specific endurance test (Bangsbo test) and 30 m sprint with 10 m lap times. RESULTS The Bangsbo test correlated with the lowest velocity associated with VO(2)MAX (vVO(2)MAX; R(2) = 0.55, p<0.001), but not with VO(2)MAX. Sprint times at 30 m and 20 m were related to peak extension velocity and peak extension force measured during vertical jumping, but not to vertical jump height per se. The jumping force and velocity could explain 46% of the 30 m sprint performance (R(2) = 0.46, p<0.001). CONCLUSION The Bangsbo test and 30 m sprint test correlate with vVO(2)MAX and vertical jump force and velocity respectively. The Bangsbo test does not give a good estimate of VO(2)MAX in young soccer players.

Abstract
A retrospective study was done for 95 eyes of Egyptian children in whom I.O.L. implantation was performed between 1985 and 1986 to treat unilateral cataract due to trauma or congenital or aphakia. The average range of follow up period was three to four years old. It was revealed that I.O.L. In traumatic cataract gave the best results (as regards the visual acuity with minimal complications) especially with anterior chamber lenses and still the secondary implantation of A.C. lenses had to some extent better results than that of primary A.C. lenses. In congenital cataract, P.C. lenses gave the worst results. Again, the older the age of the children, the better the results of I.O.L. implantation.
