British Society of Gastroenterology (BSG) and British Society of Paediatric Gastroenterology, Hepatology and Nutrition (BSPGHAN) joint consensus guidelines on the diagnosis and management of eosinophilic oesophagitis in children and adults.

BACKGROUND: Eosinophilic oesophagitis (EoE) is an increasingly common cause of dysphagia in both children and adults, as well as one of the most prevalent oesophageal diseases with a significant impact on physical health and quality of life. We have provided a single comprehensive guideline for both paediatric and adult gastroenterologists on current best practice for the evaluation and management of EoE. METHODS: The Oesophageal Section of the British Society of Gastroenterology was commissioned by the Clinical Standards Service Committee to develop these guidelines. The Guideline Development Group included adult and paediatric gastroenterologists, surgeons, dietitians, allergists, pathologists and patient representatives. The Population, Intervention, Comparator and Outcomes process was used to generate questions for a systematic review of the evidence. Published evidence was reviewed and updated to June 2021. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system was used to assess the evidence and make recommendations. Two rounds of voting were held to assess the level of agreement and the strength of recommendations, with 80% consensus required for acceptance. RESULTS: Fifty-seven statements on EoE presentation, diagnosis, investigation, management and complications were produced with further statements created on areas for future research. CONCLUSIONS: These comprehensive adult and paediatric guidelines of the British Society of Gastroenterology and British Society of Paediatric Gastroenterology, Hepatology and Nutrition are based on evidence and expert consensus from a multidisciplinary group of healthcare professionals, including patient advocates and patient support groups, to help clinicians with the management patients with EoE and its complications.

Comparison of an e-learning package with lecture-based teaching in the management of supraventricular tachycardia (SVT): a randomised controlled study.

INTRODUCTION: To compare the impact of an e-learning package with theoretical teaching on the ability of both graduate and undergraduate medical students to learn the management of supraventricular tachycardia. METHODS: We conducted a randomised, controlled, study at two Welsh medical schools. Participants were graduate-entry and undergraduate medical students, who were randomised (in a 1:1 ratio) to either 1 hour of training using an e-learning package or an hour of lecture-based teaching. The outcome was a comparison, within each group and between groups, of median scores achieved in assessments of knowledge through completion of preintervention, immediate post intervention and 2 weeks postintervention questionnaires. RESULTS: Of the 97 participants available for randomisation, 47 underwent teaching using the e-learning package and 50 were taught in the lecture group. Median scores were higher in the e-learning package group than the lecture group, though this difference was not statistically significant (4.00 vs 3.00; p=0.08) immediately after intervention. At 2 weeks post intervention, median scores in the e-learning package group were significantly higher than the median scores in the lecture group (4.00 vs 3.00; p=0.002). This was despite a subanalysis of the results demonstrating that subjects in the lecture group reported having seen more cases compared with those in the e-learning group (32 vs 13; p=0.002). Further, there was a significant fall in score over 2 weeks in the group receiving lecture-based teaching, but no such decrease in those using the e-learning package. CONCLUSION: E-learning seems to be the preferred method of learning and the method that confers longer retention time for both postgraduate and undergraduate medical students.

Endoscopy findings in patients on dual antiplatelet therapy following percutaneous coronary intervention.

PURPOSE OF STUDY: This study examines the associations between dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) and gastrointestinal bleeding (GIB), to explore possible predictors of outcomes. STUDY DESIGN: Retrospective analysis of 3342 patients who underwent PCI between 1 August 2011 and 31 December 2018 in a single centre was carried out. Oesophagogastroduodenoscopies (OGDs) for patients 12 months post-PCI were analysed. RESULTS: Blood loss occurred in 2% of all (3342) patients post-PCI within 12 months. 128 patients (63% male, mean age (SD) of 69.8 (10) years) who had PCI subsequently underwent an OGD within 12 months of the index PCI procedure. GIB occurred within the first 30 days of DAPT in 36% (n=13/36) of cases. There were no thrombotic events associated with cessation of one antiplatelet agent. Increased age, haemoglobin (Hb) ≤109 g/L and Glasgow-Blatchford score ≥8 were associated with increased 12-month mortality. An Hb drop of ≥30 g/L was a sensitive and specific marker for significant pathology and evidence of bleeding on OGD (sensitivity=0.83, specificity=0.81). CONCLUSIONS: GIB bleeding occurred infrequently in the patients post-PCI on DAPT. Risk assessment scores (such as Glasgow-Blatchford and Rockall scores) are useful tools to assess the urgency of OGD and need for endoscopic therapy.

Evaluation of Erythroferrone, Hepcidin, and Iron Overload Status in Iraqi Transfusion-Dependent ß-Thalassemia Major Patients.

Patients with ß-thalassemia major (ß-TM) show ineffective erythropoiesis and iron overload, which is the leading cause of mortality and organ injury. The present study aimed to investigate the relationships between two iron regulatory hormones, hepcidin and erythroferrone (ERFE) levels, and iron status parameters in Iraqi patients with ß-TM. Iron status parameters and hormones were measured in 60 patients and compared with 30 healthy controls. The results indicated significant changes in different iron status parameters, while ferritin with the ∼11-fold increase showed the most change. Significant reduction in hepcidin and an increase in ERFE levels were detected in patients when compared to the control group, while no direct correlation was identified with the other measured iron status parameters. The receiver operating characteristic (ROC) analysis showed that the z-score of the composite of ERFE + ferritin has a full diagnostic ability for ß-TM. In conclusion, our findings indicated the correlation between different iron status parameters and ferritin as the leading predictor of iron overload and two main iron regulatory hormones.

Effects of Boxing Matches on Metabolic, Hormonal, and Inflammatory Parameters in Male Elite Boxers.

Background and objectives: Boxing is a popular combat sport that requires high intensity and cooperation. However, there are limited data about the influence of boxing matches on blood parameters. The purpose of the present study was to investigate the match-induced changes in the metabolic, hormonal, and inflammatory status in male elite boxers. Materials and methods: High-level 20 male boxers with more than 5 years experience in boxing voluntarily participated in this study. Venous blood samples of the boxers, before and after combat, were taken for determination of the plasma parameters. Results: Our results indicated that a 9-min boxing match caused significant increases in plasma energy fuels (glucose and lactate), metabolic hormones (insulin, adrenocorticotropic hormone (ACTH), cortisol, and growth hormone), inflammatory markers (interleukin-1ß (IL-1ß), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α)), muscle damage indicators (alanine aminotransferase (ALT) and aspartate aminotransferase (AST)), and oxidative stress marker (SOD). A decrease in total oxidant status (TOS) was also considered. However, there were no significant alterations in the plasma levels of androgenic hormone (free and total testosterone), anabolic hormone (IGF-1), lipids (total cholesterol, triglyceride, high-density lipoprotein (HDL), and low-density lipoprotein (LDL)), kidney function markers (creatinine and urea), and minerals (iron (Fe) and magnesium (Mg)). Conclusion: Elevations in the level of energy fuels and metabolic hormones of the boxers could be taken as a reflection of high-energy turnover during combat performance. The increases in inflammatory and tissue damage indicators may possibly be an indication of traumatic injury. Understanding the biochemical changes that occur during boxing match could be valuable to optimize the performance improvement of the athletes.

UK guidelines on oesophageal dilatation in clinical practice.

These are updated guidelines which supersede the original version published in 2004. This work has been endorsed by the Clinical Services and Standards Committee of the British Society of Gastroenterology (BSG) under the auspices of the oesophageal section of the BSG. The original guidelines have undergone extensive revision by the 16 members of the Guideline Development Group with representation from individuals across all relevant disciplines, including the Heartburn Cancer UK charity, a nursing representative and a patient representative. The methodological rigour and transparency of the guideline development processes were appraised using the revised Appraisal of Guidelines for Research and Evaluation (AGREE II) tool.Dilatation of the oesophagus is a relatively high-risk intervention, and is required by an increasing range of disease states. Moreover, there is scarcity of evidence in the literature to guide clinicians on how to safely perform this procedure. These guidelines deal specifically with the dilatation procedure using balloon or bougie devices as a primary treatment strategy for non-malignant narrowing of the oesophagus. The use of stents is outside the remit of this paper; however, for cases of dilatation failure, alternative techniques-including stents-will be listed. The guideline is divided into the following subheadings: (1) patient preparation; (2) the dilatation procedure; (3) aftercare and (4) disease-specific considerations. A systematic literature search was performed. The Grading of Recommendations Assessment, Develop-ment and Evaluation (GRADE) tool was used to evaluate the quality of evidence and decide on the strength of recommendations made.

Securing a cardiology speciality training programme in the UK: how did other people do it?

BACKGROUND: Application to cardiology specialty training is competitive with uncertainty among candidates as to what the secret recipe for a successful appointment is. We aimed to investigate objective variables, which were demonstrated by successful appointees to cardiology training schemes in the UK. METHODS: Data from successful cardiology applicants for the years 2014 to 2016 were obtained from the Joint Royal Colleges of Physicians Training Board under the Freedom of Information Act. These data included basic demographics as well as objective scores awarded for selection categories such as qualifications, academic, teaching and other achievements. RESULTS: There were a total of 976 applicants during the study period, of whom 423 were successfully appointed, generating a competition ratio of 2.3 applicants for each position. There was an increasing proportion of successful female applicants (22% in 2014, 28% in 2015 and 32% in 2016). Median scores for postgraduate exams (14/14), presentations (6/6) and quality improvement (10/10) scores corresponded to maximum possible scores, whereas median scores for additional undergraduate and postgraduate degrees were 0. Median scores for prizes, publications and teaching experience were 6/10, 4/8 and 9/10, respectively. CONCLUSION: The secret to a successful cardiology training appointment is associated with completion of all postgraduate clinical exams, completion and presentation of quality improvement projects, national presentations and substantial teaching achievements. At least half of the successful candidates had no additional undergraduate or postgraduate degrees but had evidence of some prizes and publications. The ratio of successful female candidates is rising, but remains less than males in cardiology training.

SYN-004 (ribaxamase), an oral beta-lactamase, mitigates antibiotic-mediated dysbiosis in a porcine gut microbiome model.

AIM: To evaluate an antibiotic inactivation strategy to protect the gut microbiome from antibiotic-mediated damage. METHODS AND RESULTS: SYN-004 (ribaxamase) is an orally delivered beta-lactamase intended to degrade penicillins and cephalosporins within the gastrointestinal tract to protect the microbiome. Pigs (20 kg, n = 10) were treated with ceftriaxone (CRO) (IV, 50 mg kg-1 , SID) for 7 days and a cohort (n = 5) received ribaxamase (PO, 75 mg, QID) for 9 days beginning the day before antibiotic administration. Ceftriaxone serum levels were not statistically different in the antibiotic-alone and antibiotic + ribaxamase groups, indicating ribaxamase did not alter systemic antibiotic levels. Whole-genome metagenomic analyses of pig faecal DNA revealed that CRO caused significant changes to the gut microbiome and an increased frequency of antibiotic resistance genes. With ribaxamase, the gut microbiomes were not significantly different from pretreatment and antibiotic resistance gene frequency was not increased. CONCLUSION: Ribaxamase mitigated CRO-mediated gut microbiome dysbiosis and attenuated propagation of the antibiotic resistance genes in pigs. SIGNIFICANCE AND IMPACT OF THE STUDY: Damage of the microbiome can lead to overgrowth of pathogenic organisms and antibiotic exposure can promote selection for antibiotic-resistant micro-organisms. Ribaxamase has the potential to become the first therapy designed to protect the gut microbiome from antibiotic-mediated dysbiosis and reduce emergence of antibiotic resistance.

Genetic analysis and identification of SSR markers associated with rice blast disease in a BC2F1 backcross population.

Rice (Oryza sativa L.) blast disease is one of the most destructive rice diseases in the world. The fungal pathogen, Magnaporthe oryzae, is the causal agent of rice blast disease. Development of resistant cultivars is the most preferred method to achieve sustainable rice production. However, the effectiveness of resistant cultivars is hindered by the genetic plasticity of the pathogen genome. Therefore, information on genetic resistance and virulence stability are vital to increase our understanding of the molecular basis of blast disease resistance. The present study set out to elucidate the resistance pattern and identify potential simple sequence repeat markers linked with rice blast disease. A backcross population (BC2F1), derived from crossing MR264 and Pongsu Seribu 2 (PS2), was developed using marker-assisted backcross breeding. Twelve microsatellite markers carrying the blast resistance gene clearly demonstrated a polymorphic pattern between both parental lines. Among these, two markers, RM206 and RM5961, located on chromosome 11 exhibited the expected 1:1 testcross ratio in the BC2F1 population. The 195 BC2F1 plants inoculated against M. oryzae pathotype P7.2 showed a significantly different distribution in the backcrossed generation and followed Mendelian segregation based on a single-gene model. This indicates that blast resistance in PS2 is governed by a single dominant gene, which is linked to RM206 and RM5961 on chromosome 11. The findings presented in this study could be useful for future blast resistance studies in rice breeding programs.

Influence of patient and diagnostic parameters on reported retear rates after arthroscopic rotator cuff repair.

PURPOSE: The purpose of this meta-analysis was to investigate patient and diagnostic parameters influencing the reported rates of recurrent rotator cuff defects after ARCR. METHODS: PubMed, EMBASE, Cochrane Library and Scopus databases were searched for clinical studies on tendon defects after ARCR. Imaging modalities, definitions, detection time points, and other known patient risk factors (patient age, tear severity, grade of fatty infiltration, repair technique) as well as reported defect rates were extracted. A meta-analysis of proportion and meta-regression analysis were used to investigate independent variables influencing reported defect rates. RESULTS: Of 109 articles reviewed, the diagnostic studies used magnetic resonance imaging (MRI) only (n = 56), ultrasound (US) only (n = 28), MRI or computed tomography (CT) arthrography (CTA, n = 14) or a combination of US, MRI and CTA (n = 11) up to 57 months after ARCR. Definitions of tendon defects were highly variable, including those of partial tendon healing with insufficient thickness defined as either an acceptable outcome (n = 72) or a recurrent defect (n = 22). Reported defect rates demonstrated highly significant heterogeneity between studies and groups. Follow-up time and the evaluation of partial tendon healing were independent factors of the defect rate alongside age, tear severity and repair technique. The type of imaging did not significantly alter defect rates. CONCLUSION: A number of specific factors significantly alter the rates of rotator cuff defects reported after ARCR. Standardized protocols in clinical practice are required for consistent diagnosis of recurrent defects after ARCR. LEVEL OF EVIDENCE: IV.

Retinoblastoma protein and MyoD function together to effect the repression of Fra-1 and in turn cyclin D1 during terminal cell cycle arrest associated with myogenesis.

The acquisition of skeletal muscle-specific function and terminal cell cycle arrest represent two important features of the myogenic differentiation program. These cellular processes are distinct and can be separated genetically. The lineage-specific transcription factor MyoD and the retinoblastoma protein pRb participate in both of these cellular events. Whether and how MyoD and pRb work together to effect terminal cell cycle arrest is uncertain. To address this question, we focused on cyclin D1, whose stable repression is required for terminal cell cycle arrest and execution of myogenesis. MyoD and pRb are both required for the repression of cyclin D1; their actions, however, were found not to be direct. Rather, they operate to regulate the immediate early gene Fra-1, a critical player in mitogen-dependent induction of cyclin D1. Two conserved MyoD-binding sites were identified in an intronic enhancer of Fra-1 and shown to be required for the stable repression of Fra-1 and, in turn, cyclin D1. Localization of MyoD alone to the intronic enhancer of Fra-1 in the absence of pRb was not sufficient to elicit a block to Fra-1 induction; pRb was also recruited to the intronic enhancer in a MyoD-dependent manner. These observations suggest that MyoD and pRb work together cooperatively at the level of the intronic enhancer of Fra-1 during terminal cell cycle arrest. This work reveals a previously unappreciated link between a lineage-specific transcription factor, a tumor suppressor, and a proto-oncogene in the control of an important facet of myogenic differentiation.

Environmental endocrine disruptors: Effects on the human male reproductive system.

Incidences of altered development and neoplasia of male reproductive organs have increased during the last 50 years, as shown by epidemiological data. These data are associated with the increased presence of environmental chemicals, specifically "endocrine disruptors," that interfere with normal hormonal action. Much research has gone into testing the effects of specific endocrine disrupting chemicals (EDCs) on the development of male reproductive organs and endocrine-related cancers in both in vitro and in vivo models. Efforts have been made to bridge the accruing laboratory findings with the epidemiological data to draw conclusions regarding the relationship between EDCs, altered development and carcinogenesis. The ability of EDCs to predispose target fetal and adult tissues to neoplastic transformation is best explained under the framework of the tissue organization field theory of carcinogenesis (TOFT), which posits that carcinogenesis is development gone awry. Here, we focus on the available evidence, from both empirical and epidemiological studies, regarding the effects of EDCs on male reproductive development and carcinogenesis of endocrine target tissues. We also critique current research methodology utilized in the investigation of EDCs effects and outline what could possibly be done to address these obstacles moving forward.

Hospital doctors' Opinions regarding educational Utility, public Sentiment and career Effects of Medical television Dramas: the HOUSE MD study.

OBJECTIVES: To evaluate the opinions of practicing clinicians on medical television dramas and the effects these series have on society as well as their own practice. DESIGN, SETTING AND PARTICIPANTS: Observational study using a structured questionnaire disseminated among doctors of all grades and specialties at one tertiary centre and two large secondary care district general hospitals in Wales, United Kingdom. Three hundred and seventy-two questionnaires were distributed over a 3-month period, with 200 completed questionnaires received (response rate, 54%). MAIN OUTCOME MEASURES: Frequency and reasons for watching these programs, and opinions regarding realism, educational value and public perception, evaluated by doctors' grades and specialties. Identification of work practice with any observed traits in fictional doctors was also analysed. RESULTS: 65% of doctors surveyed admitted to watching these programs on more than one occasion. Junior doctors (interns and resident medical officers) were more regular viewers. Most doctors who admitted to watching medical dramas did so for entertainment purposes (69%); 8% watched for educational purposes and, of these, 100% watched House MD, 82% felt that these dramas were unrepresentative of daily practice, and 10% thought that they accurately portrayed reality. Most of the positive responses were from junior doctors. 61% of doctors identified some aspect of their clinical practice with another doctor (fictional or non-fictional; most junior doctors identified with a fictional doctor, compared with non-fictional role models for more senior practicing clinicians. CONCLUSIONS: This survey shows that a large body of the medical workforce watches medical television dramas and that such programs exercise a growing influence on the practice of junior doctors, particularly those in physicianly specialties. The reasons for certain role model selections remain unknown and may require further evaluation.

A young child with bilateral diaphragmatic palsy after bilateral bidirectional Glenn shunt.

A 13-months old boy was admitted in National Heart Foundation Hospital and Research Institute on 3 August 2011 with the diagnosis of Dextrocardia, A-V discordance, DORV, large perimembranous VSD, severe infundibular and valvular PS, bilateral SVC. He was operated on 10 August 2011. Bilateral bidirectional Glenn shunt was done off pump along with interruption of PDA. Antegrade pulmonary blood flow was minimized by tight PA banding. Baby was extubated 3 hours after surgery but had to reintubate immediately due to intense respiratory distress. Subsequent three trials of extubation failed. Chest x-ray revealed elevation of both the hemidiaphragm. Ultrasonogram of abdomen and Bronchogram along with fluoroscopy done and bilateral diaphragmatic palsy was diagnosed. Tracheostomy was done on 25th August 2011. Plication of left hemidiaphragm was done on 27th August and right hemidiaphragm plication was done on 10th September 2011. Though it took long period of time we managed to take him out of ventilator on 57th postoperative day. He was oxygen dependent for a period of time and finally he managed to take his own breath without tracheostomy tube from 67th postoperative day. After a long eventful postoperative hospital stay he was discharged home on 78th postoperative day. Discharge Chest x-ray revealed well expanded lung with flattened diaphragm. Echo revealed well functioning bilateral Glenn shunt. Tracheostomy wound healed nicely and there was no evidence of tracheal stenosis.

Utilizing triethylenetetramine-functionalized MIP-206 for highly efficient removal of Pb(II) from wastewater.

The global concern over heavy metal pollution necessitates urgent measures to safeguard human health and the environment. This study focuses on employing triethylenetetramine (TETA)-functionalized MIP-206-OH (TMIP-206) as an effective adsorbent for removing Pb(II) from wastewater. TMIP-206 was synthesized via a hydrothermal method followed by functionalization with TETA. Kinetic studies demonstrate that lead removal on TMIP-206 conforms to the pseudo-second-order model, indicating an efficient removal process. Experimental results reveal that TMIP-206 aligns with the Langmuir isotherm, exhibiting a maximum removal capacity of 267.15 mg/g for lead ions. The sorption efficiency of TMIP-206 for Pb ions remains stable across six cycles, with a reduction of less than 15%. Optimal adsorption performance is observed at a pH of 6. These findings underscore the potential of TMIP-206 as an alternative for adsorbing Pb(II) from aqueous environments, addressing the global challenge of heavy metal pollution. Future research should explore the scalability and long-term stability of TMIP-206-based adsorbents to enhance their practical applicability in diverse environmental contexts and contribute to broader strategies for mitigating heavy metal contamination.

The insights provided offer valuable guidance for planning and sustaining resource centers, positioning them as indispensable allies in the global pursuit of universal immunization coverage.

Risk of anterior cruciate ligament injury in population with elevated body mass index.

Aim Anterior cruciate ligament (ACL) injury is among the most common orthopaedic injuries. The elevated body mass index (BMI) can contribute to non-contact ACL injury. This study aims to assess the risk of ACL injury among elevated BMI population people (BMI ≥25 Kg\m2 ). Methods This is a cross sectional study that was conducted in a tertiary care centre in the Kingdom of Saudi Arabia. A total of 302 patients, who had an ACL reconstruction surgery in a ten-year-period (January 2008 to December 2018) were included. Results Sport related injury is significantly higher among the overweight and obese groups (p=0.002). Moreover, the combined ACL tear was higher among the overweight and obese groups (p=0.001). In univariate regression analysis for the selected baseline characteristics, it was found that individuals with higher BMI have chance to develop combined (ACL) injury 2 times higher when compared to those with isolated ACL injury (p=0.003). Also, the ACL type, mode of injury, types of injury and type of sports were statistically significant in univariate regression analysis. However, only the mode of injury was statistically significant after controlling the confounding factors. Other selected variables like type of sport, type of injury and ACL type were not significant. Conclusion Elevated BMI was associated with a higher risk of developing combined ACL tear as well as reinjured individuals.

Genetic Influence of Fracture Nonunion (FNU): A Systematic Review.

Purpose: Nonunion of fractures occurs in about 15% of all fractures causing repeated surgical interference and prolonged morbidity. We performed this systematic review to assess genes and polymorphisms influencing fractures' nonunion (FNU). Methods: We searched between 2000 and July 2022 in PubMed, EMBASE, the Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews, Genome Wide Association Studies (GWAS) Catalog, and the Science Citation Index, with the keywords nonunion of fractures, genetic influence, and GWAS. The exclusion criteria were review articles and correspondence. The data were retrieved to determine the number of studies, genes, and polymorphisms and the total number of subjects screened. Results: A total of 79 studies were reported on nonunion of fractures and genetic influence. After the inclusion and exclusion criteria, ten studies with 4402 patients' data were analyzed. Nine studies were case-controlled, and 1 GWAS. It was identified that patients with polymorphisms in the genes ANXA3, BMP2, CALY, CYR61, FGFR1, IL1ß, NOG, NOS2, PDGF gene, and TACR1 are prone to develop a nonunion of fractures. Conclusion: We believe that for patients who develop an early nonunion of fractures, a genetic study should be conducted for single nucleotide polymorphism (SNP) and genes so that alternative and more aggressive treatment can be performed to heal fractures without prolonged morbidity.

Fears and misconceptions toward COVID-19 vaccination among Syrian population: A cross-sectional study.

Background and Aims: Despite the significant milestone of vaccine discovery, the spread of misinformation and pseudoscientific claims has resulted in an increasing number of people refusing vaccination in Syria. In this study, we aimed to explore fears and misconceptions towards COVID-19 vaccines among the Syrian population. Methods: We conducted a nationwide cross-sectional study between January and May 2022, using a convenience sample of 10,006 participants aged at least 18 years and living in Syria. We administered a validated online/paper questionnaire and conducted face-to-face interviews. We used SPSS software (version 26) for statistical analysis, assessing our data using frequency and χ 2 tests, with p < 0.05 considered statistically significant. Results: The majority of the participants were female 6048 (60.4%), university degree holders 7304 (73%), and from urban areas 8015 (80.1%). Approximately half of the participants 5021 (50.2%) belonged to the medical sector (49% had concerns about the vaccine). Females, university degree holders, and participants with a history of symptomatic COVID-19 were more likely to have fears about the vaccines. The main concerns about the vaccines were the rapid development, fears of blood clots, and common side effects. The prevalence of some misconceptions was relatively high, such as the belief that the vaccine is an experiment or a secret plan to reduce the population. Reliable sources are crucial to fight misleading information on social media. Conclusion: COVID-19 vaccine is key to controlling the spread, but acceptance rate is critical. High variability in vaccine acceptance and high vaccine hesitancy can affect the efforts to terminate the COVID-19 pandemic. Addressing the barriers associated with the acceptance of COVID-19 vaccination will be the cornerstone to achieving maximum vaccination coverage. It is important to consider the reasons for refusing the COVID-19 vaccine when interpreting the results of any study on vaccine attitudes among the Syrian population.
