This study is the first bibliometric analysis of vegan-related research. This article aims to identify and organize fundamental and influential works across several decades in order to gain insight into global trends in vegan-related research. We searched the Scopus database and included all relevant articles published from 1960 (inception) to 2020. We limited our search to English language articles containing the terms “vegan,” “vegans,” or “veganism” in the title or abstract. We included all types of articles that were published in journals. We conducted a bibliometric analysis with the open-source R programming software-based Bibliometrix package. There were a total of 1440 relevant articles published in 664 journals over a span of 60 years. The first article was published in 1962. The average publication rate was 9.68 articles per year. The top journal was Nutrients with total publication of 85 (5.9%) articles and 924 total citations. The United States was the leading country with 471 articles and the University of Oxford was the most prolific institution with 59 articles. There was a total of 4586 authors with an average of 28 citations per article. McCarty from the United States was the leading author. The keyword “vegan” was the most used term with 411 occurrences, widely published in Nutrients by the United States authors. We conclude that the United States is the leading country in the field of vegan-related research and, if the trajectory we noted continues, the global trend in vegan-related research is likely to continue surging.
Background and Objective: Distinguishing attributes of stroke subtypes is crucial to establish appropriate planning for patient care and preventive measures. This study aims to compare the associations among demographic characteristics, risk factors, clinical manifestations, and outcomes of different stroke subtypes in a Malaysian stroke-ready hospital. Methods: The study utilized data that were collected from the local hospital-based stroke database, which is part of the Perai Regional Integrated Stroke Intervention System. The database is representative of the population in mainland Penang. All confirmed local ischaemic stroke (IS) and haemorrhagic stroke (HS) cases aged 18 years and above admitted to Hospital Seberang Jaya from 1st January 2010 to 31st December 2019 were included. Descriptive and inferential statistics were employed. Results: There was a total of 1,805 patients with 1,572 (87.1%) IS patients and 233 (12.9%) HS patients. The mean (SD) age for IS patients was 62.75 (12.08) and 60.51 (13.65) for HS patients. Generally, there were more male than female patients: 957 (60.9%) male IS patients and 137 (58.8%) male HS patients. A significantly higher proportion of IS patients were aged ≥60 years old (59.9%, p=0.021), of Indian origin (15.5%, p=0.034), had diabetes (51.2%, p<0.001), hyperlipidaemia (17.8%, p<0.001), ischaemic heart disease (10.9%, p=0.011) and were smokers (54.2%, p=0.028) as compared to HS patients. The proportion of IS patients who exhibited hemiparesis (76.0%, p=0.012) and speech disturbances (54.8%, p=0.015) was higher than HS patients. Most IS patients ranged from no disability to moderate disability (65.3%, p<0.001) with a length of stay in the hospital of ≤ 7 days (77.6%, p<0.001). Conclusion: Significant differences were observed on risk factors between IS and HS. IS was linked mainly with hemiparesis and speech disturbances, whereas HS patients mainly exhibited headaches, nausea and vomiting, altered sensorium, and seizures, in addition to more severe stroke and poor outcomes.
Veganism, a lifestyle that encourages healthy and sustainable living, is gaining more attention. The rising demand for sustainable ways of living has stimulated research initiatives globally. We sought to comprehend the topics of interest to researchers and took a qualitative approach in examining vegan-related research trends worldwide. This article aims to provide a synthesis of underlying research themes and identify the direction of future vegan-related research. We selected relevant articles published between 1960 and 2020 from the Scopus database and performed a bibliographic coupling analysis with the open-source R programming software-based Bibliometrix package followed by a content analysis. We identified four main clusters and the associated sub-clusters for each of them: a) consumerism (cultural, social, personal, and psychological factors), b) medical and health sciences (nutrition, biomarkers, anthropometry, fat and/or cholesterol, blood glucose, gut health, blood pressure, general health, ageing and/or quality of life, physical or exercise performance, mortality or longevity, bone health, and genetics), c) food science and technology (vegan food products or by-products, vegan vitamins or supplements, and vegan food content or toxic elements), and d) environmental impacts (greenhouse gas emissions, land and water use). Our study provides a wide-ranging overview of research domains and introduces readers to key studies, concepts, and methods. These are essential to help researchers conduct more studies for effective policy prescriptions
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
