Intradural extramedullary spinal cord meningioma with a rare extradural foraminal extension: A case report
BackgroundMeningiomas are mostly benign and slow-growing neoplasms of the central nervous system. Spinal meningiomas account for up to 45% of all intradural spinal tumors in adults and up to 25%–45% of all spinal tumors. Spinal extradural meningiomas are rare and may be easily confused with malignant neoplasms.Case descriptionA 24-year-old woman was presented to our hospital with paraplegia and loss of sensation in the T7 dermatome and lower body. MRI findings showed T6-T7 right-sided intradural extramedullary and extradural lesion, measuring 1.4 cm × 1.5 cm × 3 cm, extending to the right foramen, compressing the spinal cord, and displacing it to the left. Hyperintense lesion on T2 and hypointense lesion on T1 were observed. The patient reported improvement after surgery and during follow-up. We recommend maximizing the decompression during surgery to achieve better clinical outcome. Extradural meningiomas represent 5% of all meningiomas; therefore, having an intradural on top of extradural meningioma with extraforaminal extensions makes this a unique and rare case.ConclusionMeningiomas can be easily missed in diagnosis depending on imaging and the pathognomonic pattern it represents, which can mimic other pathologies, such as schwannomas. Therefore, surgeons should always suspect their patient having a meningioma even if the pattern is not typical. Moreover, preoperative preparation, such as navigation and defect closure, must be taken in case it turns out be a meningioma instead of the presumed pathology
Vitamin D serum level predicts stroke clinical severity, functional independence, and disability—A retrospective cohort study
BackgroundStroke is a leading cause of mortality and disability and one of the most common neurological conditions globally. Many studies focused on vitamin D as a stroke risk factor, but only a few focused on its serum level as a predictor of stroke initial clinical severity and recovery with inconsistent results. The purpose of this study was to assess the relationship between serum vitamin D levels and stroke clinical severity at admission and functional independence and disability at discharge in Saudi Arabia.MethodologyA retrospective cohort study of adult ischemic stroke patients who had their vitamin D tested and admitted within 7 days of exhibiting stroke symptoms at King Abdulaziz Medical City (KAMC) Jeddah, Saudi Arabia. Based on vitamin D level, the patients were categorized into normal [25(OH)D serum level ≥ 75 nmol/L], insufficient [25(OH)D serum level is 50–75 nmol/L], and deficient [25(OH)D serum level ≤ 50 nmol/L]. The primary outcome was to assess the vitamin D serum level of ischemic stroke patients’ clinical severity at admission and functional independence at discharge. The National Institute of Health Stroke Scale (NIHSS) was used to assess the clinical severity, whereas the modified Rankin scale (mRS) was used to assess functional independence and disability.ResultsThe study included 294 stroke patients, out of 774, who were selected based on the inclusion and exclusion criteria. The mean age of the participants was 68.2 ± 13.4 years, and 49.3% were male. The patients’ distribution among the three groups based on their vitamin D levels is: normal (n = 35, 11.9%), insufficient (n = 66, 22.5%), and deficient (n = 196, 65.6%). After adjusting for potential covariates, regression analysis found a significant inverse relationship of NIHSS based on 25(OH)D serum level (beta coefficient: −0.04, SE: 0.01, p = 0.003). Patients with deficient serum vitamin D level also had significantly higher odds of worse functional independence in mRS score [OR: 2.41, 95%CI: (1.13–5.16), p = 0.023] when compared to participants with normal vitamin D level.ConclusionLow vitamin D levels were associated with higher severity of stroke at admission and poor functional independence and disability at discharge in patients with acute ischemic stroke. Further randomized clinical and interventional studies are required to confirm our findings
Improving Crisis Communication Efficiency Through Nudging. Insights From and Reflections on the COVID-19 Pandemic
Neuhaus T. Improving Crisis Communication Efficiency Through Nudging. Insights From and Reflections on the COVID-19 Pandemic. In: Al-Suqri MN, Alsalmi JM, Al-Shaqsi OS, eds. Mass Communications and the Influence of Information During Times of Crises. Advances in Information Quality and Management. Hershey, PA: IGI Global; 2022: 142-160.Human action is not rational, and this irrationality manifests itself especially in decisions under uncertainty – the COVID-19 pandemic is one example of many in this respect. At the same time, various branches of research have been able to identify systematic patterns in irrational human behavior, and these have been attempted to be subsumed under the umbrella term of 'nudging'. Nudging describes the intentional change of decision architectures with the purpose of transforming irrationalities and/or distortions of human perception into predictable action. Thus, nudging represents a potent communication tool, especially in crisis communication scenarios. After presenting the basic theoretical assumptions of nudging, two examples of highly effective crisis communication strategies employed during the COVID-19 pandemic will be used to illustrate, contextualize, and reflect on central mechanisms and workings of nudging. This chapter ends with a summary of the most central findings as well as a critical reflection on potential future fields of action
Patient characteristics infected with Middle East respiratory syndrome coronavirus infection in a tertiary hospital
Background: In April 2014, a surge in cases of Middle East respiratory syndrome coronavirus (MERS-CoV) infection was seen in Jeddah, Saudi Arabia. The aim of this study is to describe the demographic and clinical features, laboratory and radiological findings of MERS-CoV patients identified during this outbreak in a single tertiary hospital.
Methods: All laboratory-confirmed MERS-CoV cases who presented to King Faisal Specialist Hospital from March 1, 2014, to May 30, 2014, were identified. Patients' charts were reviewed for demographic information, comorbidities, clinical presentations, and outcomes.
Results: A total of 39 patients with confirmed MERS-CoV infection were identified. Twenty-one were male (54%), aged 40 ± 19 years and included 3 (8%) pediatric patients (<18-year-old). 16 (41%) patients were health care workers. Twenty-one (53%) patients were previously healthy whereas eighteen (47%) had at least one comorbidity. The predominant comorbidities included hypertension (31%), diabetes (26%), respiratory (23%), and renal disease (18%). Thirty patients (81%) were symptomatic at presentation, fever (69%) being the most common complaint. The overall mortality rate was 28%. In univariate analysis, older age, hypertension, and chronic kidney disease were associated with mortality.
Conclusions: MERS-CoV presentation varies from asymptomatic infection to severe respiratory disease causing death. Future studies to identify the risk factors for worse outcome are needed

When Bacteria Get Good: Progress, Purity, and the Making of Probiotic
Structure-Based In Silico Approaches Reveal IRESSA as a Multitargeted Breast Cancer Regulatory, Signalling, and Receptor Protein Inhibitor
Breast cancer begins in the breast cells, mainly impacting women. It starts in the cells that line the milk ducts or lobules responsible for producing milk and can spread to nearby tissues and other body parts. In 2020, around 2.3 million women across the globe received a diagnosis, with an estimated 685,000 deaths. Additionally, 7.8 million women were living with breast cancer, making it the fifth leading cause of cancer-related deaths among women. The mutational changes, overexpression of drug efflux pumps, activation of alternative signalling pathways, tumour microenvironment, and cancer stem cells are causing higher levels of drug resistance, and one of the major solutions is to identify multitargeted drugs. In our research, we conducted a comprehensive screening using HTVS, SP, and XP, followed by an MM/GBSA computation of human-approved drugs targeting HER2/neu, BRCA1, PIK3CA, and ESR1. Our analysis pinpointed IRESSA (Gefitinib-DB00317) as a multitargeted inhibitor for these proteins, revealing docking scores ranging from −4.527 to −8.809 Kcal/mol and MM/GBSA scores between −49.09 and −61.74 Kcal/mol. We selected interacting residues as fingerprints, pinpointing 8LEU, 6VAL, 6LYS, 6ASN, 5ILE, and 5GLU as the most prevalent in interactions. Subsequently, we analysed the ADMET properties and compared them with the standard values of QikProp. We extended our study for DFT computations with Jaguar and plotted the electrostatic potential, HOMO and LUMO regions, and electron density, followed by a molecular dynamics simulation for 100 ns in water, showing an utterly stable performance, making it a suitable drug candidate. IRESSA is FDA-approved for lung cancer, which shares some pathways with breast cancers, clearing the hurdles of multitargeted drugs against breast and lung cancer. This has the potential to be groundbreaking; however, more studies are needed to concreate IRESSA’s role
Serum Pro-Inflammatory Cytokines and Leptin as Potential Biomarkers for Treatment Response and Toxicity in Locally Advanced Squamous Cell Carcinoma of the Head and Neck
Squamous cell carcinoma of the head and neck (HNSCC) is a globally prevalent form of cancer with significant morbidity and mortality rates. The present study examines the relationship of serum pro-inflammatory cytokines and leptin levels with the effectiveness of therapy in individuals with HNSCC and their potential role as biomarkers for treatment response and toxicity. Induction chemotherapy and concomitant chemoradiotherapy were evaluated for efficacy and safety in 52 individuals with HNSCC. Both response and toxicity were evaluated, and serum levels of pro-inflammatory cytokines Interlukin-1 beta (IL-1β), Interlukin-2 (IL-2), Interlukin-6 (IL-6), and Tumor Necrosis Factor-Alpha (TNF-α) and leptin were measured using enzyme-linked immunoassay before and after treatment. Before treatment, these measurements were made in comparison with a control group with 50 healthy people. The results showed that serum cytokines and leptin levels varied depending on the response to treatment, with patients who had a complete or partial response (PR) showing significant decreases in IL-1 β, IL-6, and TNF-α levels and significant increases in IL-2 and leptin levels after treatment, with an improvement in cachexia. These results imply that variations in serum pro-inflammatory cytokines and leptin levels are likely related to the therapeutic effectiveness in HNSCC and may act as biomarkers for treatment response
