Drug Therapies for COPD: A Bibliometric Review From 1980 to 2021

Assessment of the Relationship Between Genetic Determinants of Obesity, Unhealthy Eating Habits and Chronic Obstructive Pulmonary Disease: A Mendelian Randomisation Study

Background: Clinical studies have shown that the onset and exacerbation of chronic obstructive pulmonary disease (COPD) are related to obesity and dietary behaviours, but the genetic relationship between them is not clear.Aims: To investigate the relationship between the genetic determinants of obesity, dietary habits (alcohol consumption, intake of sweets, salt intake) and COPD.Methods: Exposure and outcome datasets were obtained from the IEU Open GWAS project. The exposure dataset includes dietary habits (Salt added to food, Sweets intake, Alcohol consumption), obesity level (represented by body mass index (BMI) and body fat percentage (BFP) data sets.). The outcome dataset includes COPD and acute COPD admissions. The collected data were imported into the RStudio software and conducted Mendelian randomisation analysis. Additionally, heterogeneity and horizontal pleiotropy tests were conducted on the data to ensure the veracity of the results.Results: The results showed that BMI was positively correlated with the risk of acute COPD admission (OR = 1.74, 95% CI 1.39-2.18) and COPD (OR = 1.81, 95%CI 1.41-2.33). In addition, BFP was also a risk factor for COPD (OR = 1.98, 95% CI 1.42-2.77) and acute exacerbation of COPD admission (OR = 1.99, 95%CI 1.43-2.77). The increase of salt, sugar and alcohol consumption will not increase the risk of COPD and the risk of hospitalisation due to COPD.Conclusion: Therefore, we should strengthen the guidance of diet and living habits of obese patients. For patients with heavier weight and higher body fat rate, they should be instructed to lose weight and fat to prevent the occurrence of COPD. For obese patients with COPD, more attention should be paid to prevent the occurrence of acute exacerbation of COPD in advance.

Perceptions of the effectiveness of non-pharmacological management of respiratory disorders among CRD patients

Chronic respiratory diseases (CRDs) are among the leading cause of mortality worldwide. While pharmacological approaches are commonly used to manage symptoms, non-pharmacological management of CRDs is considered crucial in preventing disease progression and improving patient self-efficacy. To describe the perceived effectiveness of non-pharmacological management of CRDs among CRD patients and determine whether the CRD patients perceptions of the effectiveness of non-pharmacological management are associated with their demographic characteristics. An analytic cross-sectional study design was utilized. The non-pharmacological management practices of CRD patients and their perception of the effectiveness of these therapeutic measures were assessed using a researcher-developed questionnaire. Data collection took place in primary healthcare centers in Al Ahsa, Saudi Arabia from October 2021 to March 2022. The proportion of CRD patients who perceived that non-pharmacological interventions were effective was computed. Binary logistic regression was performed to determine the association between the demographic characteristics of the respondents and their perception of the effectiveness of non-pharmacological management. Among the 390 respondents, 42% perceived that non-pharmacological measures were effective. Half of the respondents believed that smoking cessation, influenza vaccination, improving physical activity, and nutrition support helped alleviate CRD symptoms, while less than half of the respondents considered pulmonary rehabilitation, educational programs, and oxygen therapy effective measures to control symptoms. Women were found to be 3.24 times more likely to perceive non-pharmacological interventions as effective (P < .0000) compared to men. Those with university-level education were 66.6% less likely to consider non-pharmacological interventions to be effective (P < .0000) than those who completed preuniversity-level education. Age and marital status did not significantly influence perceptions of effectiveness. Differences in the perceptions of the effectiveness of various non-pharmacological measures to alleviate CRD symptoms existed among the CRD patients of Al Ahsa. The perception of effectiveness was significantly associated with the patient's gender and educational attainment.

Trends of therapy in the treatment of asthma

BACKGROUND

To better understand the development of therapy for asthma, grasp the core paradigm associated with the transformation of cognition of asthma treatment and asthma, explore potential and effective therapies for asthma, discover new biomarkers and mechanisms related to asthma treatment, find novel targets for anti-asthma drugs, and predict the future trends of asthma therapy, we used a bibliometric analysis to research articles related to the therapies for asthma published from 1983 to 2022.

METHODS

A comprehensive search was conducted to analyze the articles associated with therapy for asthma with the help of the Web of Science Core Collection (WOSCC) database from January 1, 1983 to August 14, 2022. The CiteSpace 6.1.R2 software and VOS viewer 6.1.8 software were utilized to analyze the overall structure of the network, network clusters, links between clusters, key nodes, and pathways.

RESULTS

A total of 3902 publications related to therapies on asthma were published in 3211 academic journals by a total of 14,655 authors in 3476 organizations from 87 countries or regions from 1983 to 2022. The United States published the most articles (n = 1143), followed by England (n = 574) and China (n = 405). However, the centrality of China was 0.4, higher than the United States (centrality = 0.16) and Singapore (centrality = 0.11). Akdis Cezmi published the most papers. Journal of Allergy and Clinical Immunology published the most studies on therapies for asthma. Asthma was the most frequent keyword (n = 594). The betweenness centrality value of keywords that were greater than 0.1 included airway inflammation (centrality = 0.22), double blind (centrality = 0.18), asthma (centrality = 0.17), inflammation (centrality = 0.12), and inhaled corticosteroid (centrality = 0.11).

CONCLUSIONS

The results from this biometric review provide insight into the development of therapy for asthma, the paradigm of recognition of this field, the approach of discovering new targets, exploration and combination of new mechanisms, and the frontier trend of this field in future.

Drug repositioning: A bibliometric analysis

Drug repurposing has become an effective approach to drug discovery, as it offers a new way to explore drugs. Based on the Science Citation Index Expanded (SCI-E) and Social Sciences Citation Index (SSCI) databases of the Web of Science core collection, this study presents a bibliometric analysis of drug repurposing publications from 2010 to 2020. Data were cleaned, mined, and visualized using Derwent Data Analyzer (DDA) software. An overview of the history and development trend of the number of publications, major journals, major countries, major institutions, author keywords, major contributors, and major research fields is provided. There were 2,978 publications included in the study. The findings show that the United States leads in this area of research, followed by China, the United Kingdom, and India. The Chinese Academy of Science published the most research studies, and NIH ranked first on the h-index. The Icahn School of Medicine at Mt Sinai leads in the average number of citations per study. Sci Rep, Drug Discov. Today, and Brief. Bioinform. are the three most productive journals evaluated from three separate perspectives, and pharmacology and pharmacy are unquestionably the most commonly used subject categories. Cheng, FX; Mucke, HAM; and Butte, AJ are the top 20 most prolific and influential authors. Keyword analysis shows that in recent years, most research has focused on drug discovery/drug development, COVID-19/SARS-CoV-2/coronavirus, molecular docking, virtual screening, cancer, and other research areas. The hotspots have changed in recent years, with COVID-19/SARS-CoV-2/coronavirus being the most popular topic for current drug repurposing research.
