Soccer on Social Media

In the era of digitalization, social media has become an integral part of our lives, serving as a significant hub for individuals and businesses to share information, communicate, and engage. This is also the case for professional sports, where leagues, clubs and players are using social media to reach out to their fans. In this respect, a huge amount of time is spent curating multimedia content for various social media platforms and their target users. With the emergence of Artificial Intelligence (AI), AI-based tools for automating content generation and enhancing user experiences on social media have become widely popular. However, to effectively utilize such tools, it is imperative to comprehend the demographics and preferences of users on different platforms, understand how content providers post information in these channels, and how different types of multimedia are consumed by audiences. This report presents an analysis of social media platforms, in terms of demographics, supported multimedia modalities, and distinct features and specifications for different modalities, followed by a comparative case study of select European soccer leagues and teams, in terms of their social media practices. Through this analysis, we demonstrate that social media, while being very important for and widely used by supporters from all ages, also requires a fine-tuned effort on the part of soccer professionals, in order to elevate fan experiences and foster engagement

Predicting the psychological well-being of employees based on perceived organizational support, workplace spirituality and self-efficacy

The purpose of the present research was predicting the psychological wellbeing in employees based on perceived organizational support, workplace spirituality and self- efficacy. This research has been carried out in the form of correlational design on the type of predictive study. For this purpose, among the working employees of Markazi Province Electeric Distribution Company in 2015 year, 400 persons were selected by stratified random sampling based on their job conditions, and were examined. To collecting data, the Ryff Psychological Well-being Scale, Eisenberger Survey of Perceived Organizational Support, Milliman Workplace Spirituality Scale and Sherer General Self-efficacy Scale were performed, and the obtained data were analyzed by pearson correlation coefficient and stepwise multiple regressions. The findings indicated that there were significant relationships between perceived organizational support, workplace spirituality and self-efficacy and also their components with psychological well-being. Analysis of regressions also indicated that the variables of efficacy in spite of obstacles, perceived organizational support and general sense of competence, totally explained 25 percent of the variance of psychological well-being. These variables showed also an important role in predicting of the most components of psychological well-being. As a result, it can be said that self-efficacy and perceived organizational support have an important role in predicting of psychological well-being of employees. Accordingly, the managers of organizations should perform educational programs and solutions for empowering self-efficacy, spatially efficacy in spite of obstacles and general sense of competence, and increase support of own employees, with purpose the improving of their psychological well-being

Prognostic and diagnostic values of non-coding RNAs as biomarkers for breast cancer: An umbrella review and pan-cancer analysis

Background: Breast cancer (BC) is the most common cancer in women. The incidence and morbidity of BC are expected to rise rapidly. The stage at which BC is diagnosed has a significant impact on clinical outcomes. When detected early, an overall 5-year survival rate of up to 90% is possible. Although numerous studies have been conducted to assess the prognostic and diagnostic values of non-coding RNAs (ncRNAs) in breast cancer, their overall potential remains unclear. In this field of study, there are various systematic reviews and meta-analysis studies that report volumes of data. In this study, we tried to collect all these systematic reviews and meta-analysis studies in order to re-analyze their data without any restriction to breast cancer or non-coding RNA type, to make it as comprehensive as possible.Methods: Three databases, namely, PubMed, Scopus, and Web of Science (WoS), were searched to find any relevant meta-analysis studies. After thoroughly searching, the screening of titles, abstracts, and full-text and the quality of all included studies were assessed using the AMSTAR tool. All the required data including hazard ratios (HRs), sensitivity (SENS), and specificity (SPEC) were extracted for further analysis, and all analyses were carried out using Stata.Results: In the prognostic part, our initial search of three databases produced 10,548 articles, of which 58 studies were included in the current study. We assessed the correlation of non-coding RNA (ncRNA) expression with different survival outcomes in breast cancer patients: overall survival (OS) (HR = 1.521), disease-free survival (DFS) (HR = 1.33), recurrence-free survival (RFS) (HR = 1.66), progression-free survival (PFS) (HR = 1.71), metastasis-free survival (MFS) (HR = 0.90), and disease-specific survival (DSS) (HR = 0.37). After eliminating low-quality studies, the results did not change significantly. In the diagnostic part, 22 articles and 30 datasets were retrieved from 8,453 articles. The quality of all studies was determined. The bivariate and random-effects models were used to assess the diagnostic value of ncRNAs. The overall area under the curve (AUC) of ncRNAs in differentiated patients is 0.88 (SENS: 80% and SPEC: 82%). There was no difference in the potential of single and combined ncRNAs in differentiated BC patients. However, the overall potential of microRNAs (miRNAs) is higher than that of long non-coding RNAs (lncRNAs). No evidence of publication bias was found in the current study. Nine miRNAs, four lncRNAs, and five gene targets showed significant OS and RFS between normal and cancer patients based on pan-cancer data analysis, demonstrating their potential prognostic value.Conclusion: The present umbrella review showed that ncRNAs, including lncRNAs and miRNAs, can be used as prognostic and diagnostic biomarkers for breast cancer patients, regardless of the sample sources, ethnicity of patients, and subtype of breast cancer

Onset and Effect Duration of Intrabuccal Space and Intramuscular Ketamine in Pediatrics

Background: Painful diagnostic and therapeutic procedures performed for children are routine actions. Opioids and nonsteroidal anti-inflammatory drugs such as acetaminophens are among medications that can be used for this purpose. This study aimed to compare the onset and duration of action of intrabuccal (IB, submucosal) space and intramuscular (IM) injection of ketamine in pediatrics. Materials and Methods: This clinical trial study was carried out on 126 children of 1–15 years old referred to the emergency room of Al-Zahra and Kashani Hospitals in Isfahan and divided into two 63 populated groups of IM and IB. For one group randomly, 3 mg/kg IB ketamine was administered, and for another group, ketamine was injected intramuscularly at the dose of 5 mg/kg. The drug effect, surgeon satisfaction, and complications were evaluated. Data were analyzed using SPSS software. Results: The mean of time between injection and onset of drug effect in IM group was 5.71 min, whereas in IB group, it was 4.14 min (P < 0.0001). The mean of the duration of drug effect in IM group was 45.54 min, whereas in IB group, it was 24.63 min (P < 0.0001). Complications in IM group were significantly more reported than IB group (33.3% versus 11.1%, respectively, P = 003). The median of surgeon satisfaction in IM group was 3 and in IB group was 4 which was statistically significant (P = 0.007). Conclusions: IB method is preferred over IM method, and hence, it is recommended to use

Electrospinning of Polyacrylonitrile Nanofibers and Simulation of Electric Field via Finite Element method

Objective(s): Since the electric field is the main driving force in electrospinning systems, the modeling and analysis of electric field distribution are critical to the nanofibers production. The aim of this study was modeling of the electric field and investigating the various parameters on polyacrylonitrile (PAN) nanofibers morphology and diameter. Methods: The electric field profile at the nozzle and electrospinning zone was evaluated by Finite Element Method. The morphology and diameter of nanofibers were examined by Scanning electron microscopy (SEM). Results: The results of the electric field analysis indicated that the electric field was concentrated at the tip of the nozzle. Moreover, in the spinning direction, the electric field was concentrated at the surface of the spinneret and decayed rapidly toward the surface of the collector. Increasing polymer solution concentration from 7 to 11wt.% led to increasing nanofibers diameter form 77.76 ± 19.44 to 202.42 ± 36.85. Conclusions: Base on our results, it could be concluded that concentration of the electric field at the tip of the nozzle is high and initiates jet and nanofibers formation. PAN nanofibers can be transformed to carbon nanofibers which have various applications in biomedicine

The Effect of Ondansetron on Reducing Nausea Caused By Ketamine in Pediatric Patients Visiting Emergency Department; a Clinical Trial

Introduction: Nausea is a common side effect of ketamine in pediatric sedation and the controversy is still ongoing regarding use of anti-nausea drugs with ketamine to reduce this side effect. Thus, the present study was done aiming to evaluate the effectiveness of ondansetron in controlling the nausea caused by intramuscular (IM) and intravenous (IV) use of ketamine in pediatric sedation and analgesia. Methods: In the present single-blind randomized clinical trial, 1-18 year old children in need of sedation were divided into 4 treatment groups of IV ketamine, IM ketamine, IV ketamine and ondansetron, and IM ketamine and ondansetron, and prevalence of nausea and vomiting was compared between the groups as the main outcome of the study. Results: 120 children were studied (the most common age group 2-7 years 66.7%; 65.8% male). 18 (15.0%) patients were affected with nausea and vomiting. The prevalence of nausea in IV ketamine, IM ketamine, IV ketamine and ondansetron, and IM ketamine and ondansetron groups was 26.7%, 16.7%, 6.7% and 10.0%, respectively. There was no significant difference between the 4 studied groups regarding rate of nausea (p = 0.17). Conclusion: Based on the results of the present study, it seems that using ondansetron along with ketamine does not reduce nausea. Contradiction between studies is indicative of the need for further studies in this regard
