[PMID: 36082127 PMCID: PMC9445883 DOI: 10.3389/fcvm.2022.956482] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Accepted: 08/03/2022] [Indexed: 11/13/2022] Open
Abstract
BackgroundIncreasing evidence has spurred a considerable evolution of concepts related to atherosclerosis, prompting the need to provide a comprehensive view of the growing literature. By retrieving publications in the Web of Science Core Collection (WoSCC) of Clarivate Analytics, we conducted a bibliometric analysis of the scientific literature on atherosclerosis to describe the research landscape.MethodsA search was conducted of the WoSCC for articles and reviews serving exclusively as a source of information on atherosclerosis published between 2012 and 2022. Microsoft Excel 2019 was used to chart the annual productivity of research relevant to atherosclerosis. Through CiteSpace and VOSviewer, the most prolific countries or regions, authors, journals, and resource-, intellectual-, and knowledge-sharing in atherosclerosis research, as well as co-citation analysis of references and keywords, were analyzed.ResultsA total of 20,014 publications were retrieved. In terms of publications, the United States remains the most productive country (6,390, 31,93%). The most publications have been contributed by Johns Hopkins Univ (730, 3.65%). ALVARO ALONSO produced the most published works (171, 0.85%). With a betweenness centrality of 0.17, ERIN D MICHOS was the most influential author. The most prolific journal was identified as Atherosclerosis (893, 4.46%). Circulation received the most co-citations (14,939, 2.79%). Keywords with the ongoing strong citation bursts were “nucleotide-binding oligomerization (NOD), Leucine-rich repeat (LRR)-containing protein (NLRP3) inflammasome,” “short-chain fatty acids (SCFAs),” “exosome,” and “homeostasis,” etc.ConclusionThe research on atherosclerosis is driven mostly by North America and Europe. Intensive research has focused on the link between inflammation and atherosclerosis, as well as its complications. Specifically, the NLRP3 inflammasome, interleukin-1β, gut microbiota and SCFAs, exosome, long non-coding RNAs, autophagy, and cellular senescence were described to be hot issues in the field.

Sweileh WM. Global research activity on mathematical modeling of transmission and control of 23 selected infectious disease outbreak. Global Health 2022; 18:4. [PMID: 35062966 PMCID: PMC8778503 DOI: 10.1186/s12992-022-00803-x] [Citation(s) in RCA: 26] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Accepted: 01/11/2022] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Mathematical analysis and modeling allow policymakers to understand and predict the dynamics of an infectious disease under several different scenarios. The current study aimed to analyze global research activity on mathematical modeling of transmission and control of several infectious diseases with a known history of serious outbreaks. METHODS Relevant publications were retrieved using a comprehensive validated search query. The database used was SciVerse Scopus. Indicators related to evolution, growth of publications, infectious diseases encountered, key players, citations, and international research collaboration were presented. RESULTS The search strategy found 5606. The growth of publications started in 1967 and showed a sharp rise in 2020 and 2021. The retrieved articles received relatively high citations (h-index = 158). Despite being multidisciplinary, Plos One journal made the highest contribution to the field. The main findings of the study are summarized as follows: (a) COVID-19 had a strong impact on the number of publications in the field, specifically during the years 2020 and 2021; (b) research in the field was published in a wide range of journals, mainly those in the field of infectious diseases and mathematical sciences; (c) research in the field was mainly published by scholars in the United States and the United Kingdom; (d) international research collaboration between active countries and less developed countries was poor; (e) research activity relied on research groups with a large number of researchers per group indicative of good author-author collaboration; (f) HIV/AIDS, coronavirus disease, influenza, and malaria were the most frequently researched diseases; (g) recently published articles on COVID-19 received the highest number of citations; and (h) researchers in the Eastern Mediterranian and South-East Asian regions made the least contribution to the retrieved articles. CONCLUSION Mathematical modeling is gaining popularity as a tool for understanding the dynamics of infectious diseases. The application of mathematical modeling on new emerging infectious disease outbreaks is a priority. Research collaboration with less developed countries in the field of mathematical epidemiology is needed and should be prioritized and funded.

Comparative efficacy and safety of interventions for treating head lice: a protocol for systematic review and network meta-analysis. BMJ Paediatr Open 2021; 5:e001129. [PMID: 34041368 PMCID: PMC8112437 DOI: 10.1136/bmjpo-2021-001129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 04/22/2021] [Accepted: 04/24/2021] [Indexed: 11/07/2022] Open
Abstract
Background Head lice infestation is a major public health problem around the globe. Its treatment is challenging due to product failures resulting from rapidly emerging resistance to existing treatments, incorrect treatment applications and misdiagnosis. Various head lice treatments with different mechanism of action have been developed and explored over the years, with limited report on systematic assessments of their efficacy and safety. This work aims to present a robust evidence summarising the interventions used in head lice. Method This is a systematic review and network meta-analysis which will be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement for network meta-analyses. Selected databases, including PubMed, Embase, MEDLINE, Web of Science, CINAHL and Cochrane Central Register of Controlled Trials will be systematically searched for randomised controlled trials exploring head lice treatments. Searches will be limited to trials published in English from database inception till 2021. Grey literature will be identified through Open Grey, AHRQ, Grey Literature Report, Grey Matters, ClinicalTrials.gov, WHO International Clinical Trials Registry and International Standard Randomised Controlled Trials Number registry. Additional studies will be sought from reference lists of included studies. Study screening, selection, data extraction and assessment of methodological quality will be undertaken by two independent reviewers, with disagreements resolved via a third reviewer. The primary outcome measure is the relative risk of cure at 7 and 14 days postinitial treatment. Secondary outcome measures may include adverse drug events, ovicidal activity, treatment compliance and acceptability, and reinfestation. Information from direct and indirect evidence will be used to generate the effect sizes (relative risk) to compare the efficacy and safety of individual head lice treatments against a common comparator (placebo and/or permethrin). Risk of bias assessment will be undertaken by two independent reviewers using the Cochrane Risk of Bias tool and the certainty of evidence assessed using the Grading of Recommendations, Assessment, Development and Evaluations guideline for network meta-analysis. All quantitative analyses will be conducted using STATA V.16. Discussion The evidence generated from this systematic review and meta-analysis is intended for use in evidence-driven treatment of head lice infestations and will be instrumental in informing health professionals, public health practitioners and policy-makers. PROSPERO registration number CRD42017073375.

Abstract
BACKGROUND The World Health Organization recommended the implementation of antimicrobial stewardship (AMS) in the clinical settings to minimize the development and spread of antimicrobial resistance (AMR). The current study aimed to assess global research activity on AMS as one measure for efforts dedicated to contain AMR. METHOD A bibliometric method was applied using Scopus. A validated search query was implemented. Bibliometric indicators and mapping were generated. The study period was from 1990 to 2019. The search query utilized the keywords "antimicrobial stewardship" or "antibiotic stewardship" in the titles or abstracts. In addition, documents with the term "restrict" or "restriction" if used with the terms "antimicrobial" or "antibiotic" were retrieved. RESULTS The search query returned 4402 documents. The keyword "antimicrobial stewardship" returned 2849 documents while the keyword "antibiotic stewardship" returned 1718 documents. The terms restrict/restriction and antimicrobial/antibiotics returned 209 documents. The number of publications and cumulative citations showed a steep and parallel increase in the last decade. The region of the Americas returned the most while the Eastern Mediterranean region returned the least. The United States (n = 1834, 41.7%) ranked first. Main research themes in the retrieved literature were the (1) impact of AMS on hospital length stay, (2) role of pharmacists, and (3) development of resistance of various pathogens. Clostridium difficile (n = 94) and Staphylococcus aureus (n = 76) were among the most frequently encountered author keywords. The Infection Control and Hospital Epidemiology journal ranked first (n = 245, 5.6%, h-index = 134) while documents published in the Clinical Infectious Diseases journal (h-index = 321) received the highest number of citations per document (70.7). At the institutional level, the US Centers for Disease Prevention and Control (n = 93, 2.1%) ranked first followed by the Imperial College London (n = 86, 2.0%). The main funding sponsors were the National Institute of Health. Pfizer, Merck, and Bayer pharmaceutical companies played a key role in funding AMS research. International research collaboration between developed (n = 3693, 83.9%) and developing countries (n = 759, 17.2%). CONCLUSION The fight against AMR is a global responsibility and implementation of AMS need to be carried out across the globe. International research collaboration between developing and developed countries should be encouraged.

Abstract
BACKGROUND Vaccine hesitancy is a growing threat to national and global health security. The current study was undertaken to provide insights into the global scientific literature on vaccine hesitancy in peer-reviewed journals. METHOD The current study was a descriptive bibliometric study. A validated search strategy on vaccine hesitancy was implemented using SciVerse Scopus. Bibliometric indicators such as (1) annual growth of publications, (2) key players, (3) research themes, (4) pathogens/diseases encountered, (5) top-cited documents, and (6) annual growth of publications stratified by world region and by age category were presented. The study period was from 1990 to 2019. RESULTS Search strategy found 2791 documents. The h-index of the retrieved literature was 89. The leading journal was Vaccine (369; 13.2%%) followed by Human Vaccines and Immunotherapeutics (129; 4.6%). Authors from the USA led with 1125 (40.3%) followed by authors from Italy (234; 8.4%) and the UK (204; 7.3%). The US CDC led with 140 (5.0%) documents followed by Emory University (USA) (81, 2.9%). The list of active authors included six from the USA while the remaining were from France, Australia, and Canada. Research themes in the retrieved literature focused on influenza, human papillomavirus, and the role of parents in immunization of their children. The region of the Americas and the European region had the greatest share of publications and showed steep growth of publications lately. Vaccine hesitancy research on adolescents was most noticed after 2007 while that on children was present all the time but escalated lately. Titles/abstracts analysis indicated that 621(22.3%) documents focused on influenza, 392 (14.0%) focused on Human papillomavirus, and 292 (10.5%) focused on measles. The top-cited documents in literature published after 2015 focused on the definition and strategies to overcome vaccine hesitancy. CONCLUSION The last decade witnessed a noticeable increase in the number of publications. Influenza vaccine and parental concerns about the human papillomavirus vaccine were the main focus of the retrieved literature. Information on vaccine hesitancy needs to be collected from all countries to build a better coalition against the anti-vaccination groups. Re-building trust in vaccines requires targeting parents by providing adequate information on the vaccines.

Abstract
Background Antimicrobial resistance (AMR) is a global health threat that requires a "One Health" approach. Of the One Health triad, the environmental component is the most dynamic and most neglected. Therefore, the objective of the current study was to assess and analyze global research activity on AMR in the environment. Methods This was a bibliometric descriptive study of publications on AMR in the environment. Publications were retrieved using SciVerse Scopus for the study period from 2000 to 2019. The search query was developed using terms and phrases related to the topic. The retrieved publications were analyzed for specific bibliometric indicators including annual growth, citation analysis, key players, research output for each world regions, research themes, and occurrences of different drug classes of antimicrobials. Visualization maps including research collaboration were created using VOSviewer program. The Hirsch (h) index was used to assess scientific impact. Results There were 2611 research articles based on the implemented research query. The retrieved documents had an average of 22 citations per document and an h-index of 122. The annual number of publications showed a steep increase from 2011 to 2019. The major research themes in the field were (1) dissemination and abundance of antibiotic-resistant genes and (2) detection of bacterial strains or antibiotic residues in various environmental isolates. The bulk of the retrieved articles (n = 899; 34.4%) originated from the European region. China led with 598 (22.9%) documents. Four of the top 10 active institutions were in China. The top 10 active countries had relatively inadequate international research collaboration. The most commonly encountered antibiotic drug classes in the retrieved articles were penicillin/cephalosporin (n = 1152 occurrences). The most frequently encountered pathogen in the retrieved publications was E. coli (n = 666). The Science of the Total Environment journal was the most prolific journal with 139 (5.3%) publications. Conclusion Scientific literature on the AMR in the environment has witnessed a steep growth lately with a leading role of China and Chinese institutions. Data on AMR in the environment need to be collected from all world regions including the Eastern Mediterranean and African regions through research collaboration and funding of research in this field.

Abstract
BACKGROUND The novel coronavirus, named as 2019-nCoV or coronavirus disease 2019 (COVID-19), has recently appeared in China and has spread worldwide, presenting a health threat to the global community. Therefore, it is important to understand the global scientific output of COVID-19 research during the early stage of the outbreak. Thus, to track the current hotspots, and highlight future directions, we performed a bibliometric analysis to obtain an approximate scenario of COVID-19 to date. METHODS Relevant studies to COVID-19 were obtained from the Scopus database during the early stage of the outbreak. We then analysed the data by using well-established bibliometric indices: document type, country, collaboration patterns, affiliation, journal name, and citation patterns. VOSviewer was applied to map and determine hot topics in this field. RESULTS The bibliometric analysis indicated that there were 19,044 publications on Scopus published on COVID-19 during the early stage of the outbreak (December 2019 up until June 19, 2020). Of all these publications, 9140 (48.0%) were articles; 4192 (22.0%) were letters; 1797 (9.4%) were reviews; 1754 (9.2%) were editorials; 1728 (9.1%) were notes; and 433 (2.3%) were others. The USA published the largest number of publications on COVID-19 (4479; 23.4%), followed by China (3310; 17.4%), Italy, (2314; 12.2%), and the UK (1981; 10.4%). British Medical Journal was the most productive. The Huazhong University of Science and Technology, Tongji Medical, and Harvard Medical School were the institutions that published the largest number of COVID-19 research. The most prevalent topics of research in COVID-19 include "clinical features studies", "pathological findings and therapeutic design", "care facilities preparation and infection control", and "maternal, perinatal and neonatal outcomes". CONCLUSIONS This bibliometric study may reflect rapidly emerging topics on COVID-19 research, where substantial research activity has already begun extensively during the early stage of the outbreak. The findings reported here shed new light on the major progress in the near future for hot topics on COVID-19 research including clinical features studies, pathological findings and therapeutic design, care facilities preparation and infection control, and maternal, perinatal and neonatal outcomes.

Abstract
Background Burnout and compassion fatigue are closely related concepts. Burnout is thought to develop from occupational stress while compassion fatigue results from being in a caregiver role leading to inability to get engaged in a caring relation. The objective of the current study was to investigate research trends, themes, citations, and key players of publications on burnout and compassion fatigue among healthcare providers. Methods A validated search query was developed and implemented in the Scopus database. The study period was all times up to 2019. Results Research query found 4416 publications. Publications started in 1978. Steep growth in the number of publications was observed in the last decade. There were seven research themes in the retrieved publications; six for burnout and one for compassion fatigue. Approximately 36% of the retrieved publications were about nurses; 36% were about physicians, 10% were about medical residents and the remaining did not include a specific profession. The retrieved publications received an average of 22.2 citations per article. Four of the top 10 active journals were in the field of nursing and two in the field of general medicine, one in public health, one in neurology, one in psychology, and one was multidisciplinary. The USA ranked first with 1292 (29.3%) articles followed by Spain (n = 248; 5.6%) and the UK (n = 247; 5.6%). Mayo Clinic was the most active institution (n = 93; 2.1%) followed by Harvard University (n = 46; 1.0%) and University of Washington, Seattle (n = 45; 1.0%). A total of 16,108 authors participated in publishing the retrieved documents, an average of 3.6 authors per article. Shanafelt, T.D. was the most active author (n = 78; 1.8%) followed by Dyrbye, L.N. (n = 43; 1.0%), and West, C.P. (n = 37; 0.8%). A total of 472 (10.7%) articles declared funding. Conclusion The current study was carried out to draw attention to the wellbeing of healthcare providers. Retrieved literature was dominated by high-income countries. Lack of information from low- and middle-income countries will hinder planning for interventional strategies and will negatively affect the health system and the patients. Health researchers in low- and middle-income countries need to focus on burn out and compassion fatigue.

Abstract
Background Assessing research activity is important for planning future protective and adaptive policies. The objective of the current study was to assess research activity on climate change and health with an emphasis on infectious diseases. Method A bibliometric method was applied using SciVerse Scopus. Documents on climate change and human health were called “health-related literature” while documents on climate change and infectious diseases were called “infection-related literature”. The study period was from 1980 to 2019. Results The search query found 4247 documents in the health-related literature and 1207 in the infection-related literature. The growth of publications showed a steep increase after 2007. There were four research themes in the health-related literature: (1) climate change and infectious diseases; (2) climate change, public health and food security; (3) heat waves, mortality, and non-communicable diseases; and (4) climate change, air pollution, allergy, and respiratory health. The most frequently encountered pathogens/infectious diseases in the infection-related literature were malaria and dengue. Documents in infection-related literature had a higher h-index than documents in the health-related literature. The top-cited documents in the health-related literature focused on food security, public health, and infectious diseases while those in infection-related literature focused on water-, vector-, and mosquito-borne diseases. The European region had the highest contribution in health-related literature (n = 1626; 38.3%) and infection-related literature (n = 497; 41.2%). The USA led with 1235 (29.1%) documents in health-related literature and 365 (30.2%) documents in infection-related literature. The Australian National University ranked first in the health-related literature while the London School of Hygiene & Tropical Medicine ranked first in the infection-related literature. International research collaboration was inadequate. Documents published in the Environmental Health Perspectives journal received the highest citations per document. A total of 1416 (33.3%) documents in the health-related literature were funded while 419 (34.7%) documents in the infection-related literature were funded. Conclusion Research on climate change and human health is on the rise with research on infection-related issues making a good share. International research collaboration should be funded and supported. Future research needs to focus on the impact of climate change on psychosocial, mental, innovations, policies, and preparedness of health systems.

[PMID: 31470803 PMCID: PMC6716890 DOI: 10.1186/s12876-019-1076-z] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2019] [Accepted: 08/23/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The pathways and mechanism by which associations between the gut microbiome and the brain, termed the microbiome-gut-brain axis (MGBA), are manifest but remain to be fully elucidated. This study aims to use bibliometric analysis to estimate the global activity within this rapidly developing field and to identify particular areas of focus that are of current relevance to the MGBA during the last decade (2009-2018). METHODS The current study uses the Scopus for data collection. We used the key terms "microbiome-gut-brain axis" and its synonyms because we are concerned with MGBA per se as a new concept in research rather than related topics. A VOSviewer version 1.6.11 was used to visualize collaboration pattern between countries and authors, and evolving research topics by analysis of the term co-occurrence in the title and abstract of publications. RESULTS Between 2009 and 2018, there were 51,504 published documents related to the microbiome, including 1713 articles related to the MGBA: 829 (48.4%) original articles, 658(38.4%) reviews, and 226 (13.2%) other articles such as notes, editorials or letters. The USA took the first place with 385 appearances, followed by Ireland (n = 161), China (n = 155), and Canada (n = 144).The overall citation h-index was 106, and the countries with the highest h-index values were the USA (69), Ireland (58), and Canada (43). The cluster analysis demonstrated that the dominant fields of the MGBA include four clusters with four research directions: "modeling MGBA in animal systems", "interplay between the gut microbiota and the immune system", "irritable bowel syndrome related to gut microbiota", and "neurodegenerative diseases related to gut microbiota". CONCLUSIONS This study demonstrates that the research on the MGBA has been becoming progressively more extensive at global level over the past 10 years. Overall, our study found that a large amount of work on MGBA focused on immunomodulation, irritable bowel syndrome, and neurodevelopmental disorders. Despite considerable progress illustrating the communication between the gut microbiome and the brain over the past 10 years, many issues remain about their relevance for therapeutic intervention of many diseases.

Oxf Med Case Reports 2019; 2019:omz049.

Abstract
Tungiasis is a highly prevalent yet neglected disease of populations affected by extreme poverty. It causes great discomfort and pain, leads to social stigmatization and, when left untreated, can cause serious complications. Although natural repellents have been shown to be effective, too little is being done in terms of systematic prevention and treatment. In addition, self-treatment (usually extraction of fleas with non-sterile sharp instruments) comports high risks of infection, notably with viral hepatitis and human immunodeficiency virus. In this article, we report seven severe cases of tungiasis in children living in a refugee camp in Tanzania, all of whom were treated with surgical extraction of the fleas because the topical treatment (dimethicone) was not available. Refugee camps—particularly in sub-Saharan Africa where tungiasis is endemic—should be considered high-risk areas for the condition. Aid organizations should engage in active case searching, and health promotion should be systematically carried out.

Abstract
Background The Syrian conflict has created the worst humanitarian crisis of our time with approximately half of Syria’s pre-war population killed or forced to flee their homes. The current study aimed to analyze peer-reviewed literature published on Syrian refugees and displaced people. Methods A bibliometric methodology was implemented using Scopus database after retrieving documents relevant to Syrian refugees and displaced people. Findings In total, 323 documents were retrieved. Research articles constituted 71.2% (n = 230) of the retrieved documents. The bulk (61.6%; n = 199) of the retrieved documents were in health-related fields. Research domains of the retrieved health-related documents were mainly in the field of mental and psychosocial (17.3%; n = 56), infectious diseases (15.2%; n = 49), health policy and systems (16.4%; n = 53), maternal and reproductive health (15.2%; n = 49), and non-communicable diseases (NCD) (7.4%; n = 24). Authors from research institutions in the United States produced the highest number of publications (24.5%; n = 79), followed by Turkey (21.4%; n = 69) and Lebanon (10.2%; n = 33). The American University of Beirut was the most active (5.6%; n = 18) research institution. Aside from Lebanon and Jordan, there was very little contribution from other Arab states. Conflict and Health was the most active journal (5.3%; n = 17) in publishing on Syrian refugees and displaced people. Conclusion The study highlighted some particular research gaps – most notably the limited research on NCDs. There was also modest international research collaboration and engagement from Arab countries aside from Lebanon and Jordan.

Sweileh WM. Analysis of global research output on diabetes depression and suicide. Ann Gen Psychiatry 2018; 17:44. [PMID: 30386407 PMCID: PMC6198430 DOI: 10.1186/s12991-018-0214-2] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2018] [Accepted: 10/16/2018] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Diabetic patients, during the course of the disease, are most likely to experience depressive symptoms that might ultimately lead to suicidal ideation or suicide. The size of literature in diabetes depression/suicide is a good indicator of national and international efforts to address psychological co-morbidities associated with diabetes mellitus (DM). Therefore, the objective of this study was to give a comprehensive analysis, both quantitative and qualitative, of scientific literature in diabetes depression/suicide. METHODS SciVerse Scopus was used to retrieve relevant literature up to 2016. RESULTS In total, 1664 journal documents were retrieved with an average of 26.9 citations per article and an h-index of 98. Publications started in 1949 but showed a steep and noticeable increase after 2001. Retrieved articles were published in 641 different journals with Diabetes Care journal being the top productive one with a total of 130 (7.8%) articles. Researchers from 83 different countries participated in retrieved publications. Researchers from the United States of America participated in publishing 685 articles. There was a strong and positive correlation between research output and Gross Domestic Product (r = 0.083; p < 0.001) but not with prevalence or mortality caused by DM. Researchers from 4870 different institutions/organizations participated in publishing retrieved articles. Publications from the University of Washington, Seattle, USA had the highest h-index (38), while "VA medical centers" had the highest number of publications (75; 4.5%). In total, 5715 authors appeared in retrieved articles giving an average of 3.4 authors per article. Top cited articles focused on prevalence, impact of depression on glycemic control, and potential risk of diabetic complications. The total number of publications in depression/suicide in diabetic patients was lesser than that in cardiac (1938) or in cancer (1828) patients. However, publications in diabetes depression/suicide exceeded those in cardiac and cancer in the last 2 years of the study period. CONCLUSION The current study showed a noticeable growth of publications indicative of the importance of this topic. Research focusing on the psychiatric component of diabetes mellitus needs to be strengthened and encouraged. At the practical level, screening for depression/suicide among patients attending primary healthcare clinics is needed to optimize health and quality of life of diabetic patients.
