Performance of Red Cell Distribution Width-to-Platelet Ratio as a Screening Tool of Liver Fibrosis Based on Transient Elastography in Chronic Hepatitis B Infection
Full text linkBackground: Identifying liver fibrosis is crucial for initiating antiviral therapy for hepatitis B infection. Liver biopsy is the gold standard for assessing the degree of fibrosis. However, a liver biopsy is an invasive procedure that carries some risks. This study aimed to evaluate the diagnostic capabilities of the red cell distribution width-to-platelet ratio (RPR) and compare its efficacy for determining the degree of fibrosis in patients with chronic hepatitis B infection with that of the aspartate aminotransferase-to-platelet ratio index (APRI) and the Fibrosis-4 index (FIB-4). Methods: This was a retrospective study conducted on patients with chronic hepatitis B infection who had transient elastography results at the Gastroenterology Hepatology Clinic, Dr. Hasan Sadikin General Hospital, Bandung, between January and December 2024. Statistical analysis was performed using receiver operating characteristic curves to determine the diagnostic values and cutoff points of the RPR, APRI, and FIB-4 to detect liver fibrosis based on Transient Elastography in patients with Chronic Hepatitis B infection. Results: A total of 114 patients with chronic hepatitis B infection were included in this study (42 with significant fibrosis and 72 with nonsignificant fibrosis). The area under the curve (AUC) of the RPR was 0.873 (p 0.0538, whereas the AUCs of the APRI and FIB-4 were 0.833 (p < 0.001) and 0.746 (p < 0.001), respectively. Conclusion: The RPR has a higher diagnostic performance than the APRI and is superior to the FIB-4 in assessing the degree of fibrosis in patients with chronic hepatitis B infection. The RPR is a simple and cost-effective test and has the potential to be a screening tool for patients with hepatitis B infection
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“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

No full textCurrent Guidelines on Antithrombotic Management in Patients Undergoing Gastrointestinal Endoscopy
Full text linkEndoscopic procedure is commonly used to make diagnosis or therapy. Endoscopy has risk on the procedure or after the procedure. Patient with antithrombotic therapy, both antiplatelet and/or anticoagulant, for underlying diseases has higher risk for bleeding and thromboembolic events in this procedure. The physician should consider risk and benefit for adjusting the antithrombotic therapy, in addition to minimize bleeding and thromboembolic events. For low risk procedure, adjustments in antithrombotic therapy usually not necessarily needed. For high risk procedure, there are several adjustments based on the type of medication and patient’s condition in specific. European Society of Gastrointestinal Guidelines Endoscopy (ESGE) and British Society of Gastrointestinal (BSG); American Society of Gastrointestinal Endoscopy (ASGE); and lastly Asian Pacific Association of Gastroenterology (APAGE) and Asian Pacific Society for Digestive Endoscopy (APSDE) have published guidelines to help physician to make decisions regarding antithrombotic therapy management during endoscopy. This article compares and contrasts the approach of each guideline, in design to help the decision-making process. However, each patient’s clinical condition may differ from one to another and should be considered carefully in making a final decision
A Quest for Survival: A Review of the Early Biomarkers of Pancreatic Cancer and the Most Effective Approaches at Present
No full textPancreatic cancer (PC) is the most lethal type of cancer; it has the lowest 5-year survival rate among all other types of cancers. More than half of PC cases are diagnosed at an advanced stage due to PC’s insidious and non-specific symptoms. Surgery remains the most efficacious treatment option currently available, but only 10–20% of PC cases are resectable upon diagnosis. As of now, the sole biomarker approved by the United States Food and Drug Administration (US-FDA) for PC is carbohydrate antigen 19-9 (CA19-9); however, its use is limited for early diagnosis. An increasing number of studies have investigated a combination of biomarkers. Lately, there has been considerable interest in the application of a liquid biopsy, including the utilization of microRNAs (miRNAs), circulating tumor DNA (ctDNA), and circulating tumor cells (CTCs). Screening for PC is indicated for high-risk patients; studies on new diagnostic models combined with biomarkers for early detection have also shown promising results in terms of the ability of these models and biomarkers to aid clinicians in deciding on whether to start screening. This review seeks to provide a concise overview of the advancements in relation to existing biomarkers and explore novel strategies for the early detection of PC
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
3193 The First Case of Hepatocellular Carcinoma in Male Patient Arising From Resolved Hepatitis B After Seroconversion Without Liver Cirrhosis in Indonesia
No full textDispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
