Understanding Chinese Medicine Patterns of Rheumatoid Arthritis and Related Biomarkers
No full textBackground: A considerable number of Rheumatoid Arthritis (RA) patients only experience side effects from treatment, with little to no actual pain relief. The combination of disease diagnosis in biomedicine and multi-disciplinary integrative approaches such as Chinese Medicine (CM), can help to identify different functional diagnosis of RA in the context of biomarker discovery. We aimed to analyse CM patterns in RA and their biomarker profiles. Methods: Four electronic databases (web of science, CINAHL, Scopus and PubMed) were searched. The reference list of all identified reports and articles were searched for additional studies. All study designs were included and no date limits were set. Studies were considered if they were published in English and explored the possible biomarkers profiles in RA patients, classified according to the American College of Rheumatology and categorized in CM as either cold, heat/hot or deficiency patterns. Methodological quality of included studies was assessed using checklists adapted from the ©Critical Appraisal Skills Programme by two independent reviewers. A narrative synthesis was conducted, using thematic analysis. Results: A total of 10 articles were included. The studies examined 77 healthy volunteers and 1150 RA patients categorized as cold, heat/hot or deficiency pattern and related biomarkers were identified individually or concomitantly. Conclusions: CM pattern differentiation based on clinical signs and symptoms showed a diverse range of biomolecules, proteins and genes from RA patients correlated well with cold, heat/hot or deficiency phenotype-based CM patterns and could be used as diagnostic biomarkers for early detection, disease monitoring and therapeutic targets
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Chinese medicine functional diagnosis: An integrative insight to understand rheumatoid arthritis of the hand
No full textIntroduction: Chinese medicine (CM), may provide insights into understanding the neuro-immunological mechanisms involved in Rheumatoid Arthritis (RA). The objective of this study was to ascertain if objective assessment strategies could help to determine CM functional diagnosis and if the complicated issues surrounding the symptoms of RA of the hand could be more easily understood by using the Shang Han Lun. Methods: First, 190 RA patients were stratified into two groups: (1) “hand pain worsened by handgrip” or (2) “hand pain worsened by thumb resistance”. Second, a CM diagnosis of patients with “hand pain worsened by handgrip” was performed, obtained through inspection, auscultation, interrogation and palpation. Third, clinical features based on data from tongue-diagnosis were assessed by two CM doctors. Results: (1) 79.5% of the participants showed worsening hand pain by handgrip; (2) all these patients showed concomitant presence of imbalances and intermingled symptoms; (3) clinical findings of the invasion of the pathogen agent algor/“cold” were: cold hands (62.9%), tearing and localized pain with gradual onset (82.9%), worse pain upon cold exposure (82.9%), pain relief by applying warmth to the affected area (62.9%), tongue exhibiting a hyaline (85.7%) and white coating (52.4%). Conclusions: This study provides new options for assessing the CM diagnosis, which may improve RA treatment strategies. Identification of joint non-related symptoms and pathogenic external factors such as algor/“cold” may help understanding activation of specific immunological mechanisms, changes of capillary endothelium and the microcirculation disturbances. Overactivation of the functional defence mechanisms by algor/“cold” seem to be of utmost importance for RA symptoms
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Effectiveness of Acupuncture on Pain, Functional Disability, and Quality of Life in Rheumatoid Arthritis of the Hand: Results of a Double-Blind Randomized Clinical Trial.
No full textBackground: Rheumatoid arthritis (RA) is characterized by pain, functional disability, poor quality of life (QoL), high socioeconomic impact, and annual costs of over $56 billion in the United States. Acupuncture (AC) is widely in use; however, studies show severe methodological shortcomings, did not consider the functional diagnosis for the allocation of acupoints and their results showed no differences between verum and control groups.
Objective: The authors aimed to objectively assess the safety and efficacy of AC treatments for RA.
Methods: 105 RA patients with a functional diagnosis of a ‘‘Pivot syndrome’’ or ‘‘Turning Point syndrome’’ were randomly assigned to (1) verum-AC (verum acupoints), (2) control-AC (sham acupoints—points outside of the conduits/meridians and of the extra-conduits), or (3) waiting list (each group n = 35). AC groups experienced the exact same number, depth, and stimulation of needles. Assessments took place before and 5 min after AC with follow-ups over 4 weeks.
Results: (1) Verum-AC significantly improved self-reported pain (Z = -5.099, p < 0.001) and pressure algometry (Z = -5.086, p < 0.001); hand grip strength (Z = -5.086, p < 0.001) and arm strength (Z = -5.086, p < 0.001); health status improved significantly ( p < 0.001, Z = -4.895); QoL improved significantly in 7/8 survey domains; and number of swollen joints (Z = -2.862, p = 0.004) and tender joints (Z = -3.986, p < 0.001) significantly decreased. (2) Control-AC showed no significant changes, except in self-reported pain improvement. (3) Waiting list group showed an overall worsening.
Conclusion: This is the first double-blind controlled study on AC in RA of the hand that objectively and specifically assesses positive effects supporting its integration in rheumatology. Acupoint allocation according to Chinese Medicine functional diagnoses is extremely relevant to assess AC effectiveness in a patient group primarily defined by a ‘‘western’’ medicine diagnosis. Based on clear allocation criteria for acupoints, the authors minimized the possible bias of unspecific and suggestive effects on the control group, showed the specific effects of the points chosen, improved efficacy, and identified an evidence base for AC
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
