Hossain R, Ibrahim RB, Hashim HB

World Neurosurg, 2023 Jul;175:57-68.
PMID: 37019303 DOI: 10.1016/j.wneu.2023.03.115

To develop a research overview of brain tumor classification using machine learning, we conducted a systematic review with a bibliometric analysis. Our systematic review and bibliometric analysis included 1747 studies of automated brain tumor detection using machine learning reported in the previous 5 years (2019-2023) from 679 different sources and authored by 6632 investigators. Bibliographic data were collected from the Scopus database, and a comprehensive bibliometric analysis was conducted using Biblioshiny and the R platform. The most productive and collaborative institutes, reports, journals, and countries were determined using citation analysis. In addition, various collaboration metrics were determined at the institute, country, and author level. Lotka's law was tested using the authors' performance. Analysis showed that the authors' publication trends followed Lotka's inverse square law. An annual publication analysis showed that 36.46% of the studies had been reported in 2022, with steady growth from previous years. Most of the cited authors had focused on multiclass classification and novel convolutional neural network models that are efficient for small training sets. A keyword analysis showed that "deep learning," "magnetic resonance imaging," "nuclear magnetic resonance imaging," and "glioma" appeared most often, proving that of the several brain tumor types, most studies had focused on glioma. India, China, and the United States were among the highest collaborative countries in terms of both authors and institutes. The University of Toronto and Harvard Medical School had the highest number of affiliations with 132 and 87 publications, respectively.

Rodd HD, Graham A, Tajmehr N, Timms L, Hasmun N

Int Dent J, 2020 Oct 08.
PMID: 33031573 DOI: 10.1111/idj.12624

BACKGROUND: Molar incisor hypomineralisation (MIH) is a common developmental dental condition that presents in childhood. Areas of poorly formed enamel affect one or more first permanent molars and can cause opacities on the anterior teeth. MIH presents a variety of challenges for the dental team as well as functional and social impacts for affected children.
OBJECTIVES: Here, we provide an up-to-date review of the epidemiology, aetiology, diagnosis and clinical management of MIH.
MATERIALS AND METHODS: A review of the contemporary basic science and clinical literature, relating to MIH, was undertaken using information obtained (up to 10 April 2020) from the electronic databases PubMed, Scopus, Web of Science and the Cochrane Library.
RESULTS: There is a growing body of evidence relating to the aetiology, presentation and clinical management of MIH. Current knowledge appears to be focused on potential genetic aspects, as well as the development and validation of indices for the diagnosis and management of MIH. There has also been increasing recognition of the global and individual burden of this common condition.
CONCLUSIONS: Dental health professionals should regularly appraise the basic science and clinical MIH literature to ensure that they provide the best possible short- and long-term care for their young patients.

PMID: 33822812 DOI: 10.1371/journal.pone.0249788

BACKGROUND: Coronavirus disease 2019 (COVID-19), a pandemic disease caused by the severe acute respiratory syndrome coronavirus 2 started to spread globally since December 2019 from Wuhan, China. Fever has been observed as one of the most common clinical manifestations, although the prevalence and characteristics of fever in adult and paediatric COVID-19 patients is inconclusive. We aimed to conduct a systematic review and meta-analysis to estimate the overall pooled prevalence of fever and chills in addition to fever characteristics (low, medium, and high temperature) in both adult and paediatric COVID-19 patients.
METHODS: The protocol of this systematic review and meta-analysis was registered with PROSPERO (CRD42020176327). PubMed, Scopus, ScienceDirect and Google Scholar databases were searched between 1st December 2019 and 3rd April 2020 without language restrictions. Both adult (≥18 years) and paediatric (<18 years) COVID-19 patients were considered eligible. We used random-effects model for the meta-analysis to obtain the pooled prevalence and risk ratio (RR) with 95% confidence intervals (CIs). Quality assessment of included studies was performed using the Joanna Briggs Institute critical appraisal tools. Heterogeneity was assessed using the I² statistic and Cochran's Q test. Robustness of the pooled estimates was checked by different subgroups and sensitivity analyses.
RESULTS: We identified 2055 studies, of which 197 studies (n = 24266) were included in the systematic review and 167 studies with 17142 adults and 373 paediatrics were included in the meta-analysis. Overall, the pooled prevalence of fever in adult and paediatric COVID-19 patients were 79.43% [95% CI: 77.05-81.80, I2 = 95%] and 45.86% [95% CI: 35.24-56.48, I2 = 78%], respectively. Besides, 14.45% [95% CI: 10.59-18.32, I2 = 88%] of the adult COVID-19 patients were accompanied with chills. In adult COVID-19 patients, the prevalence of medium-grade fever (44.33%) was higher compared to low- (38.16%) and high-grade fever (14.71%). In addition, the risk of both low (RR: 2.34, 95% CI: 1.69-3.22, p<0.00001, I2 = 84%) and medium grade fever (RR: 2.79, 95% CI: 2.21-3.51, p<0.00001, I2 = 75%) were significantly higher compared to high-grade fever, however, there was no significant difference between low- and medium-grade fever (RR: 1.17, 95% CI: 0.94-1.44, p = 0.16, I2 = 87%). 88.8% of the included studies were of high-quality. The sensitivity analyses indicated that our findings of fever prevalence for both adult and paediatric patients are reliable and robust.
CONCLUSIONS: The prevalence of fever in adult COVID-19 patients was high, however, 54.14% of paediatric COVID-19 patients did not exhibit fever as an initial clinical feature. Prevalence and risk of low and medium-grade fevers were higher compared to high-grade fever.

Malaysian Journal of Medicine and Health Sciences, 2020;16(106):205-212.
MyJurnal

The role of dietitians involves not solely on clinical responsibilities. Additionally, operation management responsibil- ities such as managing human labor, financial resources, and problem solver are the tasks that a dietitian look after. It is reported to be challenging and stressful and could affect job satisfaction levels in the working environment. This scoping review aimed to explore the job satisfaction level and skills needed among dietitians to assume management responsibilities at their workplace. This study was completed using PRISMA guidelines. Online databases (Scopus and Science Direct) were used to identify papers published from 2000 to 2019. We selected English publications from the United States, Australia, South Africa, Korea, and the United Kingdom that used job satisfaction as a pri- mary or secondary outcome. Studies were included if they addressed dietitians who were involved in clinical work, food service, and management in their dietetic practices. Findings on existing skills, including managerial skills, communication, teamwork, and time management among dietitians with management responsibilities, have helped to enhance the job satisfaction and work quality of the dietetic profession. The findings would be useful for human resource management in the organisation, preserving the professional identity of a dietitian.

Fulltext Sinensetin: An Insight on Its Pharmacological Activities, Mechanisms of Action and Toxicity

Han Jie L, Jantan I, Yusoff SD, Jalil J, Husain K

Front Pharmacol, 2020;11:553404.
PMID: 33628166 DOI: 10.3389/fphar.2020.553404

Sinensetin, a plant-derived polymethoxylated flavonoid found in Orthosiphon aristatus var. aristatus and several citrus fruits, has been found to possess strong anticancer activities and a variety of other pharmacological benefits and promising potency in intended activities with minimal toxicity. This review aims to compile an up-to-date reports of published scientific information on sinensetin pharmacological activities, mechanisms of action and toxicity. The present findings about the compound are critically analyzed and its prospect as a lead molecule for drug discovery is highlighted. The databases employed for data collection are mainly through Google Scholar, PubMed, Scopus and Science Direct. In-vitro and in-vivo studies showed that sinensetin possessed strong anticancer activities and a wide range of pharmacological activities such as anti-inflammatory, antioxidant, antimicrobial, anti-obesity, anti-dementia and vasorelaxant activities. The studies provided some insights on its several mechanisms of action in cancer and other disease states. However, more detail mechanistic studies are needed to understand its pharmacological effects. More in vivo studies in various animal models including toxicity, pharmacokinetic, pharmacodynamic and bioavailability studies are required to assess its efficacy and safety before submission to clinical studies. In this review, an insight on sinensetin pharmacological activities and mechanisms of action serves as a useful resource for a more thorough and comprehensive understanding of sinensetin as a potential lead candidate for drug discovery.

Shrestha S, Danekhu K, Kc B, Palaian S, Ibrahim MIM

Ther Adv Drug Saf, 2020;11:2042098620922480.
PMID: 32587678 DOI: 10.1177/2042098620922480

Background: Bibliometric analyses have been used previously to study the measures of quality and impact of research performed in several health-related areas such as adverse drug reactions (ADRs) and pharmacovigilance (PV), etc. This method can assess the research performance of publications quantitatively and statistically. There is no evidence of bibilometric studies analyzing ADRs and PV from Nepal. Therefore, the present study aimed to assess scientific output on ADRs and PV-related research activities in Nepal using a bibliometric analysis of publications from 2004 January to December 2018, that is, 15 years.
Methods: A systematic search was conducted in PubMed, Web of Science, Google Scholar, Scopus and Nepal Journal Online (NepJOL) databases. 'Adverse Drug Reactions' or 'ADRs' or 'ADR' or 'Adverse drug reaction' or 'AE' or 'Adverse Event' or 'Drug-Induced Reaction' or 'Pharmacovigilance' or 'PV' and 'Nepal'. The search covered 15 years (January 2004 to December 2018) of study on ADRs and PV in Nepal. Only articles retrieved from databases were included, whereas published/unpublished drug bulletins, pharmacy newsletters and thesis were excluded. The articles thus retrieved were recorded, and thereafter analyzed. Word count code was used for the analysis of keywords used in the retrieved articles.
Results: A total of 124 articles were retrieved, with the highest rate of publications in 2006 and 2007, with 16 papers each. Among the articles, 10 (8.1%) were published in Kathmandu University Medical Journal (KUMJ). Single papers were published in 38 different journals. Brief reports (1.6%), case reports (31.2%), case series (0.8%), education forums (0.8%), letters to the editor (5.6%), original research articles (41.9%), review articles (9.7%), short communications and short reports (8.1%) on ADRs and PV were recorded. Out of 124 papers, 52 (41.9%) were original research publications. The majority (74.1%) of research was done in the category of ADR incidence, types, prevention, and management, followed by policy and suggestions for strengthening national and regional pharmacovigilance centers of Nepal (14.5%).
Conclusions: During the study years, there was an increase in scientific publications on drug safety. A total of 124 published articles were found during bibliometric analysis of ADRs and PV research activities in Nepal.

Mahi M, Ismail I, Phoong SW, Isa CR

Environ Sci Pollut Res Int, 2021 Jul;28(27):35327-35345.
PMID: 34002315 DOI: 10.1007/s11356-021-14367-7

Energy efficiency (EE) is an evolving research aspect for researchers, businesses, and policymakers for its undeniable role in meeting increasing energy demand, reducing CO2 emissions, and tackling climate change. This paper provides a review of the current state of EE research by mapping the research landscape in business and economics to understand the socioeconomic dimensions within these research areas. To identify key information, we examine the trends and characteristics of 2935 relevant scientific publications over a 30-year period from 1990 to 2019 in the Social Science Citation Index of the Web of Science database using bibliometric analysis with a R language package called 'bibliometrix'. Our analysis shows an increasing trend in publications from 2006 onwards; the period remarkably coincides with the implementation phase of the Kyoto protocol in 2005. Accordingly, we observe that EE research has a strong association with issues like CO2 emissions, climate change, sustainability, and the growing importance of these issues in recent years. Thus, our findings provide crucial understandings by incorporating a wide array of scientific outputs in response to calls for greater theoretical clarification of EE research. These findings provide insights into the current state of the art of, and identify crucial areas for future, research. Hence, our research assists in formulating environmentally sustainable policies to tackle the adverse effects of CO2 emissions and related climate change through providing critical grasps on the scholarly development related to EE.

Fulltext Optimizing total ammonia-nitrogen concentration for enhanced microbial fuel cell performance in landfill leachate treatment: a bibliometric analysis and future directions

Ishaq A, Said MIM, Azman SB, Abdulwahab MF, Jagun ZT

Environ Sci Pollut Res Int, 2023 Aug;30(36):86498-86519.
PMID: 37454007 DOI: 10.1007/s11356-023-28580-z

Untreated landfill leachate can harm the environment and human health due to its organic debris, heavy metals, and nitrogen molecules like ammonia. Microbial fuel cells (MFCs) have emerged as a promising technology for treating landfill leachate and generating energy. However, high concentrations of total ammonia-nitrogen (TAN), which includes both ammonia and the ammonium ion, can impede MFC performance. Therefore, maintaining an adequate TAN concentration is crucial, as both excess and insufficient levels can reduce power generation. To evaluate the worldwide research on MFCs using landfill leachate as a substrate, bibliometric analysis was conducted to assess publication output, author-country co-authorship, and author keyword co-occurrence. Scopus and Web of Science retrieved 98 journal articles on this topic during 2011-2022; 18 were specifically evaluated and analysed for MFC ammonia inhibition. The results showed that research on MFC using landfill leachate as a substrate began in 2011, and the number of related papers has consistently increased every 2 years, totaling 4060 references. China, India, and the USA accounted for approximately 60% of all global publications, while the remaining 40% was contributed by 70 other countries/territories. Chongqing University emerged as one of the top contributors among this subject's ten most productive universities. Most studies found that maintaining TAN concentrations in the 400-800 mg L-1 in MFC operation produced good power density, pollution elimination, and microbial acclimatization. However, the database has few articles on MFC and landfill leachate; MFC ammonia inhibition remains the main factor impacting system performance. This bibliographic analysis provides excellent references and future research directions, highlighting the current limitations of MFC research in this area.

BMC Geriatr, 2020 02 03;20(1):39.
PMID: 32013895 DOI: 10.1186/s12877-020-1444-0

BACKGROUND: Depression is one of the most common psychiatric disorders in the older adult and one of the most common risk factors for suicide in the older adult. Studies show different and inconsistent prevalence rates in Iran. This study aims to determine the prevalence of severe depression in Iranian older adult through a meta-analysis approach.
METHODS: The present meta-analysis was conducted between January 2000-August 2019. Articles related to the subject matter were obtained by searching Scopus, Sciencedirect, SID, magiran, Barakat Knowledge Network System, Medline (PubMed), and Google Scholar databases. The heterogeneity of the studies was evaluated using I2 index and the data were analyzed in Comprehensive Meta-Analysis software.
RESULTS: In a study of 3948 individuals aged 50-90 years, the overall prevalence of severe depression in Iranian older adult was 8.2% (95% CI, 4.14-6.3%) based on meta-analysis. Also, in order to investigate the effects of potential factors (sample size and year of study) on the heterogeneity of severe depression in Iranian older adult, meta-regression was used. It was reported that the prevalence of severe depression in Iranian older adult decreased with increasing sample size and increasing years of the study, which is significantly different (P

Scientific impact of multiple sclerosis and neuromyelitis optica spectrum disorder research from Southeast Asia: A bibliometric analysis

Espiritu AI, Leochico CFD, Separa KJNJ, Jamora RDG

Mult Scler Relat Disord, 2020 Feb;38:101862.
PMID: 31778926 DOI: 10.1016/j.msard.2019.101862

BACKGROUND: Scientific productivity in the Southeast Asian (SEA) region in the field of multiple sclerosis and neuromyelitis optica spectrum disorder (MS/ NMOSD) was hypothesized to be low in magnitude. The aim of this study was to determine and compare MS/ NMOSD research outputs among the SEA countries in terms of established bibliometric indices. The association between these productivity indices and relevant country-specific socioeconomic factors was also determined.
METHODS: A systematic review was conducted to include all relevant published MS/ NMOSD studies in the SEA indexed in MEDLINE, Embase, Scopus and CENTRAL from the inception of these databases to August 1, 2019. Quantity of research productivity was measured in terms of the total published documents. Quality of research impact was evaluated by assessing the study designs of the published reports, publications in journals with impact factor (IF) and PlumX Metrics (citations, usage, captures, mentions and social medias). Population size, gross domestic product (GDP) per capita, percentage (%) of GDP allocated to research and development (R&D), and the total number of neurologists reported in each country were obtained from reliable published data.
RESULTS: Out of 3,547 articles identified, only 142 articles fulfilled the eligibility criteria; therefore, the total number of publications in the SEA region related to MS/ NMOSD was deemed low in quantity. Most studies were cross-sectional and case reports/ series; hence, most studies offered low level of evidence. Since the aggregate scores in citations, usage, captures, mentions, and social medias in PlumX Metrics and publications in journals with IF were low, the overall quality of the published articles was considered low. Thailand (57 articles), Malaysia (40) and Singapore (29) contributed to the majority of publications on the topic-. GDP per capita was statistically correlated with usage. Percent GDP for R&D was positively correlated with total publications, usage, captures and social mediaindices.
CONCLUSION: In conclusion, the scientific impact of MS/ NMOSD in the SEA was considered low in quantity and quality. This study must encourage researchers in the SEA to produce greater volumes of high-quality publications in this particular field and motivate governments to increase % GDP for R&D for the benefit of patients suffering fromthese rare and disabling conditions.

Dela Vega MPD, Yu JRT, Espiritu AI, Jamora RDG

Neurol Sci, 2021 Jul;42(7):2683-2693.
PMID: 33880678 DOI: 10.1007/s10072-021-05266-3

BACKGROUND: Although headache is one of the most common neurologic conditions with a high disease burden, primary data on headache research from Southeast Asia (SEA) was hypothesized to be inadequate. This study aimed to evaluate research productivity among the different countries in SEA and to determine the association between specific bibliometric indices and socioeconomic factors.
METHODS: A systematic search was conducted until June 10, 2020 in Scopus, PubMed, Embase, Cochrane Central Register of Controlled Trials, and Index Medicus for South-East Asia Region to include all primary headache studies on migraine, tension-type headache, and trigeminal autonomic cephalalgia, with at least one author affiliated with a SEA country. Bibliometric indices, such as the number of publications and PlumX metrics, were obtained and correlated with the country-specific socioeconomic factors.
RESULTS: We identified 153 articles. Most of the publications (n = 43, 28.1%) were epidemiologic studies and case reports/series (n = 25, 16.3%). Migraine was the most studied primary headache subtype. Malaysia, Singapore, and Thailand were the major contributors to primary headache research in SEA. Only the percent gross domestic product for research and development correlated significantly with research productivity.
CONCLUSION: Despite the high global burden of disease, research productivity on primary headache was low in SEA. The move towards a knowledge-based economy may drive research productivity in SEA.

A Bibliometric Analysis of the Research on Social Attitudes Towards LGBT Community (2002-2022)

Yeo JY, Ting SH, Jerome C

J Homosex, 2024 Jun 06;71(7):1684-1702.
PMID: 36989378 DOI: 10.1080/00918369.2023.2186761

A bibliometric analysis was conducted to map out trends in publications on attitudes toward the LGBT community based on the 470 documents retrieved from the SCOPUS database for 2002-2022. The results revealed that the United States is the leading country contributing to the publications on attitudes toward the LGBT community and has a strong impact in the field (64.68%). The authorship analysis revealed that Flores, Woodford, and Worthen from the United States are the leading researchers in this field. Analysis of publication sources showed that the Journal of Homosexuality is the top publisher of findings on the LGBT community whereas the Journal of Interpersonal Violence and Sexuality and Culture have gained more traction among researchers in recent years. The analysis of the co-occurrence of author's keywords indicated that transgender is the gender group that is the most researched compared to other sexual identities. Negative attitudes such as homophobia, discrimination and being heterosexist toward one's sexuality or same-sex marriage are the current research foci. Religion and culture are seen as important predictors of attitudes about homosexuality and same-sex marriage policy. The study addresses the gaps in the literature by recommending future researchers to investigate attitudes toward other gender identities as a result of the revolution in sexual identities.

Fulltext Politics of disease control in Africa and the critical role of global health diplomacy: A systematic review

Chattu VK, Knight WA, Adisesh A, Yaya S, Reddy KS, Di Ruggiero E, et al.

Health Promot Perspect, 2021;11(1):20-31.
PMID: 33758752 DOI: 10.34172/hpp.2021.04

Background: Africa is facing the triple burden of communicable diseases, non-communicable diseases (NCDs), and nutritional disorders. Multilateral institutions, bilateral arrangements, and philanthropies have historically privileged economic development over health concerns. That focus has resulted in weak health systems and inadequate preparedness when there are outbreaks of diseases. This review aims to understand the politics of disease control in Africa and global health diplomacy's (GHD's) critical role. Methods: A literature review was done in Medline/PubMed, Web of Science, Scopus, Embase, and Google scholar search engines. Keywords included MeSH and common terms related to the topics: "Politics," "disease control," "epidemics/ endemics," and "global health diplomacy" in the "African" context. The resources also included reports of World Health Organization, United Nations and resolutions of the World Health Assembly (WHA). Results: African countries continue to struggle in their attempts to build health systems for disease control that are robust enough to tackle the frequent epidemics that plague the continent. The politics of disease control requires the crafting of cooperative partnerships to accommodate the divergent interests of multiple actors. Recent outbreaks of COVID-19 and Ebola had a significant impact on African economies. It is extremely important to prioritize health in the African development agendas. The African Union (AU) should leverage the momentum of the rise of GHD to (i) navigate the politics of global health governance in an interconnected world(ii) develop robust preparedness and disease response strategies to tackle emerging and reemerging disease epidemics in the region (iii) address the linkages between health and broader human security issues driven by climate change-induced food, water, and other insecurities (iv) mobilize resources and capacities to train health officials in the craft of diplomacy. Conclusion: The AU, Regional Economic Communities (RECs), and African Centres for Disease Control should harmonize their plans and strategies and align them towards a common goal that integrates health in African development agendas. The AU must innovatively harness the practice and tools of GHD towards developing the necessary partnerships with relevant actors in the global health arena to achieve the health targets of the Sustainable Development Goals.

Effect of locally delivered doxycycline as an adjunct to scaling and root planing in the treatment of periodontitis in smokers: A systematic review of randomized controlled trials with meta-analysis and trial sequential analysis

Nath S, Pulikkotil SJ, Dharmarajan L, Arunachalam M, Jing KT

Dent Res J (Isfahan), 2020 08 14;17(4):235-243.
PMID: 33282148

Background: Scaling and root planing (SRP) for the treatment of periodontitis may be less effective in some patients. This study evaluated the effectiveness of local doxycycline as an adjunct to SRP among smokers with periodontitis compared to SRP alone in randomized controlled trials (RCTs).
Materials and Methods: For this systematic review and meta-analysis, PubMed and Scopus databases were searched till November 2018 for English publications. RCTs that compared the effect of local doxycycline adjunct to SRP among smokers with periodontitis were selected. Patient characteristics, disease characteristics, and outcome data on clinical attachment level (CAL) and periodontal probing depth at 1, 3- and 6-month follow-up was extracted. Quality of selected studies was assessed by the revised Cochrane Risk of Bias 2.0 tool. Random effects model and trial sequential analysis were performed. GRADE approach was used to assess the quality of evidence. P > 0.05 was considered as statistically significant.
Results: Five trials were included in the review. Local use of doxycycline as an adjunct to SRP was effective in gain of 1.1 mm (0.47-1.74, P = 0.091) in CAL at 6 months calculated from two studies. The evidence was of low quality, and at least a total of 866 patients are required for conclusiveness.
Conclusion: Local doxycycline as an adjunct to SRP significantly improved clinical attachment in smokers with periodontitis and can be recommended. Studies are required with long-term follow-up and patient-related outcome data.

Fulltext Periodontal Diseases as Putative Risk Factors for Head and Neck Cancer: Systematic Review and Meta-Analysis

Gopinath D, Kunnath Menon R, K Veettil S, George Botelho M, Johnson NW

Cancers (Basel), 2020 Jul 14;12(7).
PMID: 32674369 DOI: 10.3390/cancers12071893

Whether "periodontal disease" can be considered as an independent risk factor for head and neck cancer (HNC) remains controversial. The aim of the current meta-analysis was to quantitatively assess this relationship in order to determine whether this represents a true risk factor, with implications for cancer prevention and management. PubMed, Scopus, and Embase databases were systematically searched. Selective studies were reviewed, and meta-analysis was performed to estimate the pooled odds ratio (OR) with 95% confidence intervals (CIs) on eligible studies using a random effects model. In total, 21 eligible observational studies (4 cohorts and 17 case-controls) were identified for qualitative synthesis after a review of 1051 articles. Significant heterogeneity could be identified in measures utilized for reporting of periodontal disease. Meta-analysis performed on nine studies that employed objective measures for reporting periodontal disease demonstrated a significant association between periodontal disease and HNC [OR 3.17, 95% CI, 1.78-5.64]. A diseased periodontium represents an independent risk marker, and a putative risk factor, for HNC. Prospective studies with standardized measures of periodontal disease severity and extent, integrated with microbiological and host susceptibility facets, are needed to elucidate the mechanisms of this positive association and whether treatment of the former influences the incidence and outcomes for HNC.

Saleem Z, Hassali MA, Godman B, Versporten A, Hashmi FK, Saeed H, et al.

Expert Rev Anti Infect Ther, 2020 09;18(9):897-910.
PMID: 32394754 DOI: 10.1080/14787210.2020.1767593

Introduction: In view of increasing concerns with antimicrobial resistance (AMR), the World Health Organization (WHO) instituted a Global Action Plan (GAP) to address this. Area covered: One of the strategies to achieve the goals of GAP is to conduct regular surveillance of antimicrobial use through point prevalence surveys (PPS). In this review, PubMed, EBSCO, Proquest, Cinahl, and Scopus were searched for PPS of antimicrobial use published in English between January 2000 and December 2019. After systematic database screening of 2,893 articles, 60 PPS met the inclusion criteria and consequently were incorporated in this systematic review. Expert opinion: This review highlighted that most of the PPS were conducted in upper-middle and high-income countries. Prevalence of antimicrobial use was significantly higher in non-European hospitals compared with European hospitals. The domination of third-generation cephalosporin and fluoroquinolones use across all the regions suggests substantial use of broad-spectrum antimicrobials across countries. Among all identified regions around the world, India was the region where the highest use of antimicrobials was observed. Although PPS is a useful tool to assess the pattern of antimicrobial use and provides a robust baseline; however, a standardized surveillance method is needed. In order to optimize antimicrobial use, more efforts are required to improve antimicrobial use.

With increasing environmental regulation (ER), the requirements for green technology innovation (GTI) in enterprises are also rising. However, there are relatively few systematic summaries of the themes of ER-affecting GTI. Adopting the method of bibliometrics and visual analysis, this research discusses the status of research and development trends of ER-affecting GTI and summarizes the research in this field. The paper takes 738 papers from 2001 to 2021 in the core database of Web of Science as the research sample. Based on CiteSpace, this paper makes a visual analysis of the number of published papers, institutions, authors, keywords, countries (regions) and journals. The study found that to some extent, favorable collaboration between authors and institutions in this field needs to be strengthened. Research hotspots in this field include innovation, technology, performance, policy and environmental regulation. Renewable energy consumption, the pollution haven hypothesis, sustainable development, carbon dioxide emission, energy technology and environmental Kuznets curve are the current research frontiers in this field. In terms of the number of published papers, research in this field has been conducted in a national (regional) layout with China as the core force, and Italy, America, Britain, Germany and other European countries as important forces. This field covers three main research areas: enterprise performance, policy instruments and research methods, going through the start-up phase (2001-2011), the growth phase (2012-2018) and the development phase (2019-2021). Future research can further incorporate the digital economy and synergy of multiple environmental regulation policies into this field, which will continuously enrich the theoretical research system in this field. The content, methods and conclusions of research in this field are becoming increasingly diverse.

Physical Activity and Aging Research: A Bibliometric Analysis

Müller AM, Ansari P, Ebrahim NA, Khoo S

J Aging Phys Act, 2016 07;24(3):476-83.
PMID: 26671908 DOI: 10.1123/japa.2015-0188

Physical activity and aging research has burgeoned in the past few decades. However, despite the increase in scholarly publications, no attempts have been made to summarize the publication landscape and identify work that has had great impact on physical activity and aging research. We conducted a bibliometric analysis and collected publication data from 1980 to February 6, 2015, in the Web of Science Core Collection. Of 9,935 publications, most were published after 2007 and almost 60% were in the category of geriatrics and gerontology or sport sciences. Highly cited publications (n = 45) were mostly authored by researchers from US institutions and were quantitative in nature. Publications that reported on the associations between physical activity and health, or effects of physical activity on health, in older adults made up 60% of the highly cited publications. We expect more scholars from various backgrounds and geographical regions to join the conversation on physical activity and aging.
