Introduction: High altitude destinations are popular among international travelers. Travel medicine practitioners should be familiar with altitude physiology and high altitude illness recognition, prophylaxis, and management. We performed the first bibliometric analysis of high altitude medicine research. Methods: All articles published in a specialist high altitude medicine journal through April 2020 were mapped against the 34 domains in a theoretical body of knowledge. Citation counts of articles, as well as authors publishing the most articles, were obtained from Scopus. Collaboration analysis was performed using established methods. Results: Mapping of 1150 articles published from 2000 to 2020 identified the leading domains represented by high altitude medicine articles. The top five domains were altitude acclimatization and deterioration (19.4%, n=510); cardiovascular physiology (6.8%, n=180); work at altitude (6.6%, n = 174); acute mountain sickness (6.4%, n=169); respiratory and acid-base physiology (5.9%, n=155). Published articles attracted a total of 13,324 citations, with a mean of 11.6 citations per article. The average number of citations per author was 22.3. The USA was the most productive country with 432 publications (37.6%), followed by the UK (9.5%, n=109) and Switzerland (5.6%, n=64). The collaboration index for multi-authored publications increased from 3.8 in 2002 to 5.4 in 2019. Conclusion: We have performed the first comprehensive bibliometric analysis in high altitude medicine. Efforts to increase the research activity in neglected topics and to promote greater collaboration between high altitude medicine and related fields of study such as travel medicine may be worthwhile.

Abstract Background: Dementia is a large and growing health problem, and since the majority of dementia patients live at home, caring responsibilities generally fall to family members. Caregivers are often inadequately supported by formal health services and have poorer psychological and physical health. Our study aimed to compare the contributions of publications from different countries, institutions and authors and present a bibliometric analysis to determine the future hotspots and trends in research on the health of and interventions for family dementia caregivers. Methods: Studies published during 1988-2018 were extracted from the Science Citation Index Expanded of the Web of Science. Each publication was evaluated to obtain the basic information. Bibliometric analysis was used to evaluate the number or cooperation networks of publications, countries, institutions, journals, citations, authors, references, and keywords. The resulting articles were analyzed descriptively, and data were produced for VOSviewer. Results: Five hundred forty-two articles were identified.The annual number of relevant publications has increased steadily since approximately 2006. The USA has the highest number of publications (36.2%), followed by the UK (12.9%). China entered late, but research there has developed rapidly. The most productive institution, journal, and author in this field are University College London, the Journal of the American Geriatrics Society, and Orrell M from the UK, respectively. A co-occurrence analysis of keywords reveals a mainstream research focus on burden, depression, quality of life, and corresponding interventions for dementia patient caregivers. The keywords “psychosocial intervention”, “long-term”, “e-learning/online”, “communication”, and “qualitative research” reflect the latest hotspots, appearing in approximately 2017-2018. Conclusion: Our study details the performance statistics of and the main topics and trends in the research on the health of and interventions for dementia caregivers from 1988 to 2018 and provides a comprehensive analysis.

Physiologic Responses

With the growing interest in adventure travel and the increasing ease and affordability of air, rail, and road-based transportation, increasing numbers of individuals are traveling to high altitude. The decline in barometric pressure and ambient oxygen tensions in this environment trigger a series of physiologic responses across organ systems and over a varying time frame that help the individual acclimatize to the low oxygen conditions but occasionally lead to maladaptive responses and one or several forms of acute altitude illness. The goal of this Physiology in Medicine article is to provide information that providers can use when counseling patients who present to primary care or travel medicine clinics seeking advice about how to prevent these problems. After discussing the primary physiologic responses to acute hypoxia from the organ to the molecular level in normal individuals, the review describes the main forms of acute altitude illness—acute mountain sickness, high-altitude cerebral edema, and high-altitude pulmonary edema—and the basic approaches to their prevention and treatment of these problems, with an emphasis throughout on the physiologic basis for the development of these illnesses and their management.

Purpose In 2017, the Journal of Knowledge Management (JKM) celebrates its 20th anniversary. This study aims to show an updated analysis of their publications to provide a general overview of the journal, focusing on a bibliometric analysis of its publications between 1997 and 2016. Design/methodology/approach The methodology involves two procedures: a performance analysis and a science mapping analysis of JKM. The performance analysis uses a series of bibliometric indicators such as h-index, productivity and citations. This analysis considers different dimensions, including papers, authors, universities and countries. VOSviewer software is used to carry out the mapping of science of JKM, which, based on the concurrence of key words and co-citation points of view, seeks to graphically analyze the structure of the references of this journal. Findings There is a positive evolution in the number of publications (although with certain oscillations), which shows a growing interest in publishing in JKM. The USA and the UK lead the publications in this journal, although at a regional level, Europe is the most productive. The low participation of emerging economies in JKM is also observed. Practical implications The paper will identify the leading trends in the journal in terms of papers, authors, institutions, countries, journals and keywords. This study is useful for obtaining a quick snapshot of what is happening in the journal. Originality/value From the historical record of JKM publications, this study presents an exclusive bibliometric analysis of its publications until 2016 and identifies its main trends.

Medical Examiners

High altitude illness (HAI) is the current accepted clinical term for a group of disorders including acute mountain sickness (AMS), high-altitude cerebral edema (HACE), and high-altitude pulmonary edema (HAPE), which occur in travelers visiting high-altitude locations. High-altitude illness is due to hypobaric hypoxia, is not associated with age or physical conditioning, and mild forms are easily treated. High-altitude cerebral edema and HAPE are medical emergencies that are fatal if not promptly treated and fortunately are uncommon. The cause of most high-altitude fatalities is not related to HAI and can be easily distinguished from HACE and HAPE; however, other causes of death may have symptoms and physical findings that overlap with HAI, making postmortem diagnosis challenging. Fatalities due to HAPE and HACE are diagnoses of exclusion. Medical examiners and coroners who work in jurisdictions with high-altitude locations should be aware of the risk factors, physiology, pathology, differential diagnosis, and classification of HAI to accurately recognize HAI as a cause of death. Medical examiners who do not work in jurisdictions with high-altitude locations may be asked to evaluate deaths that occur overseas associated with high-altitude trekking and mountaineering activities.

Objectives. The bibliometric analysis uses the citation count of an article to measure its impact in the scientific community, yet there is still no comprehensive summary of gastric disease researches via bibliometric analysis. We aimed to evaluate the situations and trends of the most cited articles in gastric disease via bibliometric analysis and to provide physicians a practical guide in assessing the most influential articles written on this subject. Methods. The 100 top-cited articles in gastric disease were compiled using Web of Science. The articles selected were evaluated for their number of citations, year of publication, country of origin, type of study, and others. Results. The database had 484,281 articles published between 1965 and 2019. The most cited article received 4,017 citations and the least received 604, with a mean of 1,149 citations. We classified the articles into seven categories: gastric cancer (n=53), Helicobacter pylori (n=17), ulcer (n=7), gastrointestinal stromal tumors (n=6), gastritis (n=5), gastric bypass surgery (n=2), and others (n=10). Altogether, 69 of the articles were from the USA (n=41), the UK (n=17), and Japan (n=11). Among all the institutions, Royal Perth Hospital led the list with 5 articles. One-quarter of authors owned three or more of these top-cited articles. The 100 papers were published in 33 journals, and most of them were clinical researches (n=47). Conclusions. Our study provides a historical perspective for the scientific progress of gastric disease, and the articles of significant findings that contributed great impact on the prevention and treatment of gastric disease had been identified.

A 55-year-old female Nepali pilgrim presented to the Himalayan Rescue Association Temporary Health Camp near the sacred Gosainkund Lake (4380 m) north of Kathmandu, Nepal, with a complaint of severe headache, vomiting and light-headedness. She was diagnosed with severe acute mountain sickness. Intramuscular dexamethasone was administered. Paracetamol (acetaminophen in the USA and Canada) and ondansetron were given as supportive management for headache and nausea. Arrangements were made to have her carried down by a porter immediately. After the descent, all her symptoms resolved. High-altitude pilgrims are a more vulnerable group than trekkers and mountaineers. Pilgrims generally have a rapid ascent profile, have low awareness of altitude illness and are strongly motivated to gain religious merit by completing the pilgrimage. As a result, there is a high incidence of altitude illness among pilgrims travelling to high-altitude pilgrimage sites.

Purpose International Journal of Lean Six Sigma (IJLSS) has completed a decade. To celebrate the same, this study aims to review the articles published in IJLSS from its inception to the year 2020. The journal’s trends and professional impact over the years are investigated and potential future research directions are proposed. Design/methodology/approach A bibliometric analysis comprising of citation, co-citation and keyword co-occurrence methods is used on all the articles published in IJLSS till the year 2020. Content analysis is further done to analyse the type of research, type of industry studied and the articles’ target audience. Findings The journal has improved its reputation, productivity and impact over the years. Currently, studies published in IJLSS have been cited more than 5,000 times, with the most prominent themes being Six Sigma, Lean Six Sigma (LSS) and Lean in manufacturing and services. Researchers from India, the USA and the UK have contributed a significant number of publications. Most of the work published is case-based. There is a need for more empirical or survey-based research having high generalizability. Future studies should also focus on integrating LSS with emerging topics such as sustainability, Industry 4.0 and the like. Research limitations/implications The study provides evidence of the impact of IJLSS and highlights the trend in the domain of LSS. It can be of use for the editorial board members to identify potential areas to focus on in the future. Researchers can use it to further their research by working on the research gaps identified. Originality/value This paper is the first to trace the progress of IJLSS from its inception till the year 2020.

The study assessed physiological responses to induction to high altitude first to 3,500 m and then to 4,200 m and compared the time course of altitude acclimatization in two groups of male volunteers. The acutely inducted group was transported by aircraft (AI) to 3,500 m in 1 h, whereas the gradually inducted group was transported by road (RI) in 4 days. Baseline recordings of basal cardiovascular, respiratory, and blood gas variables were monitored at sea level as well as at 3,500 m on days 1, 3, 5, and 7. Blood gases were measured on day 10 also. After 15 days at 3,500 m, the subjects were inducted to 4,200 m by road, and measurements were repeated on days 1, 3, and 5, except blood gas variables, which were done on day 10 only. Acute mountain sickness symptoms were recorded throughout. The responses of RI were stable by day 3 of induction at 3,500 m, whereas it took 5 days for AI. Four days in transit for RI appear equivalent to 2 days at 3,500 m for AI. Acclimatization schedules of 3 and 5 days, respectively, for RI and AI are essential to avoid malacclimatization and/or high-altitude illness. Both groups took 3 days at 4,200 m to attain stability for achieving acclimatization.
