Mapping the knowledge structure of a gluten-free diet: a global perspective

Abstract Background A gluten-free diet (GFD) has become one of the most popular eating plans and is essential for managing gluten-related medical conditions, signs, and symptoms. Therefore, we performed a bibliometric analysis of the scientific literature on the GFD to describe the research landscape. Methods The Scopus database was searched for publications on the GFD from 1952 to 2021. A bibliometric analysis of the data was performed. VOSviewer software was used to perform visualization analysis, co-occurrence analysis, and publication trends in GFD. Results A total of 3,258 publications were retrieved. In terms of publications, Italy (n = 468, 14.36%) led in the number of publications, followed by the USA (n = 398, 12.22%) and Spain (n = 274, 8.41%). The retrieved documents earned an average of 22.89 citations per document, for a total of 74,560 citations. Since 2001, there has been a gradual growth in the number of articles published, going from 23 to more than 370 in 2021. Using the mapping terms in the title/abstract a minimum of 50 times, 291 terms were divided into two main clusters: ‘adherence to a gluten-free diet in celiac disease’ and ‘improvement of the nutritional and sensory quality of gluten-free products.’ Conclusions Over the past six decades, there has been a growing need for gluten-free bakery products and a noticeable increase in related publications. This study indicates that the “improvement of the nutritional and sensory quality of gluten-free products” will remain a hotspot in this research field for upcoming years

Mapping the output of the global literature on the links between gut microbiota and COVID-19

Abstract Background The term “human microbiota” refers to populations of microorganisms that live harmoniously in co-existence with humans. They contribute significantly to the host's immunological response when confronted with a respiratory viral infection. However, little is known about the relationship between the human microbiome and COVID-19. Therefore, our objective is to perform a bibliometric analysis to explore the overall structure and hotspots of research activity on the links between microbiota and COVID-19 at the global level. Methods The research literature on the microbiota and COVID-19 published between 2020 and 2022 was obtained from the Scopus database. Bibliometric analysis and network visualization were performed with VOSviewer. Results Of the 701 publications selected, the USA contributed the most (n = 157, 22.40%), followed by China (n = 118, 16.83%) and Italy (n = 82, 11.70%). Hotspots in this field were “COVID-19 is associated with an altered upper respiratory tract microbiome,” “the effect of antibiotics on the gut microbiome,” as well as “patient nutrition and probiotic therapy in COVID-19.” Conclusions The links between microbiota and COVID-19 remain an urgent concern at present, and the use of probiotics or/and antibiotics during the pandemic needs to be further improved. This landscape analysis of the links between the microbiota and COVID-19 will provide a basis for future research

Mapping the knowledge structure of research on insulin resistance and metabolic syndrome: a global perspective

Abstract Background Insulin resistance is a major pathogenic factor that plays a crucial role in the development of metabolic syndrome and has been proposed as one of its underlying causes. Most diagnostic criteria for metabolic syndrome do not directly include insulin resistance. Furthermore, research on insulin resistance continues to provide information on the development and treatment of metabolic syndromes and related health conditions. Therefore, this bibliometric analysis aimed to investigate the current research status and identify possible future research hotspots in the area of metabolic syndrome and insulin resistance by analyzing Scopus-based studies. Methods To collect published data on metabolic syndrome and insulin resistance, this study used the Scopus database as its data source without a particular starting date but including records up to December 31, 2022. The gathered documents were then exported to VOSviewer v.1.6.18 to analyze and visualize country collaborations and identify research areas of high interest. Results The study presents an overview of 1932 records between 1988 and 2022, focusing on metabolic syndrome and insulin resistance. Of these records, 77.33% were original journal articles, while 13.30% were review articles. Additionally, 9.35% of the documents fall under other types of publication, including letters, notes, and editorials. The United States came out on top with 463 items, accounting for 23.96% of the contributions in this field, followed by Japan in second place with 119 items (6.16%). China (n = 113, 5.85%) and the United Kingdom (n = 113, 5.85%) ranked third. Most publications on metabolic syndrome and insulin resistance focus on key terms related to the pathogenesis of insulin resistance syndrome, the use of waist circumference as a crucial clinical indicator to evaluate the risk of metabolic syndrome, and the association between metabolic syndrome and oxidative stress and a pro-inflammatory state. Conclusions This study presents the first bibliometric analysis of publications focusing on metabolic syndrome and insulin resistance. The findings of this study offer a comprehensive global perspective on the research carried out on metabolic syndrome and insulin resistance and can be an invaluable source for future research

Assessment of practices and awareness regarding the disposal of unwanted pharmaceutical products among community pharmacies: a cross-sectional study in Palestine

Abstract Background The improper disposal of pharmaceutical preparations substantially threatens human health and environmental safety. Pharmacists are responsible for properly disposing of unwanted medications and educating patients about how to do so themselves. This study aimed to assess community pharmacists’ knowledge, determine their views on how to dispose of unwanted pharmaceuticals, and assess the extent to which they realize that it is their responsibility to guide patients toward the safe disposal of expired medications. Methods A descriptive cross-sectional study was conducted between December 2021 and April 2022 among 400 practicing pharmacists who were chosen to participate by random cluster sampling. Community pharmacists’ practices, awareness, and beliefs about disposing of unused drugs were evaluated. The Statistical Package for Social Sciences (IBM-SPSS) version 21 was used for data entry and analysis. Results Of 400 pharmacists, 348 stated that they did not participate in courses on the safe disposal of unwanted medications. Disposal of drugs in the garbage, an unsafe method, was very frequently recommended by pharmacists to patients, especially regarding inhalers, antibiotics, hormonal drugs, and solid and semisolid drugs. However, many pharmacists advised patients to return their hormonal, category B, and category C drugs to the pharmacy. A total of 61.3% of pharmacists agreed and 26% strongly agreed that unsafe disposal of drugs negatively affects the environment. A total of 54.3% of the participants agreed that improper disposal of antibiotics might be a reason for increased antimicrobial resistance, and 54.5% of them agreed that improper disposal of hormonal drugs might contribute to the development of certain cancers. A total of 80.3% of the participants perceived that most unwanted drugs in pharmacies were those returned from patients. A total of 97.3% of the participants supported establishing a drug disposal system, with 77.5% choosing to have the district health board responsible for funding this system. A total of 48.5% of the participants indicated that a lack of education and awareness on the issue of getting rid of unused drugs constitutes a challenge to the safe disposal of medicines, and 66% of them said that a lack of law enforcement constitutes another challenge. A total of 95.5% of the participants agreed or strongly agreed that good training for health sector workers and organizing workshops to develop knowledge on this subject would improve practices. A total of 93.3% supported distributing educational brochures, and 92.8% supported placing special containers in every pharmacy to collect unwanted drugs. Conclusions Most pharmacists in our study returned drugs to manufacturing companies and stores, and few followed the correct methods of incineration and return of drugs to the Ministry of Health. Current data emphasize the issue of improper disposal of medicine in Palestine and the need for improved education among healthcare workers
