SURVIVAL OF PROSTATE CANCER PATIENTS WITH COMBINATION HORMONAL-RADIOTHERAPY BETTER THAN HORMONAL THERAPY
Full text linkObjective: This study aims to determine the survival of prostate cancer (PCa) patients who did not undergo radical prostatectomy, but received hormonal therapy or a combination of radiotherapy and hormonal therapy. Material & Methods: This study was an observational analytic study with a retrospective cohort design, using secondary data to determine baseline data and diagnosis of patients, and using primary data to determine the survival of prostate cancer patients who received combination hormonal and radiotherapy therapy compared with hormonal therapy alone. The analysis was performed using chi-square and contingency coefficients to assess the relationship between survival with factors such as age, stage T, N, M, clinical stage, type of therapy, and prognosis. It also used the Kaplan Maeier curve to assess the survival picture of prostate cancer patients at Sardjito General Hospital. Results: 79 patients met the inclusion criteria. The mean age of the patients was 68 ± 8.4 years. A total of 52 (65.8%) patients received hormonal therapy, and 27 (34.2%) patients received combination hormonal and radiotherapy. There were 41 (51.9%) patients remain life, while 38 (48.1%) of patients died during the monitoring. We found that the Gleason score, PSA level, and clinical stage were significantly associated with patient survival with p <0.005. The 5 years survival rate patient with local, locally advanced clinical stage and PSA level ≤20 ng/ml who received combination hormonal and radiotherapy achieved 100%. Conclusion: Combination of hormonal and radiotherapy was more improving patient survival compared with hormonal therapy only in patient with locally advanced clinical stage, PSA level ≤20 ng/ml and Gleason score ≤7
THE QUALITY OF SPERM AND FEMALE AGE AS FACTORS INFLUENCING PREGNANCY IN INTRACYTOPLASMIC SPERM INJECTION (ICSI)
No full textObjective: To evaluate the quality of sperm and the female age influence on fertilization and pregnancy rate after Intracytoplasmic Sperm Injection (ICSI) procedure. Material & Methods: This study was an observational analytic study with a retrospective cohort design. The data of infertile and subfertile male undergoing ICSI for five years were analyzed and evaluated to determine factors influencing pregnancy post-ICSI in Central General Hospital Dr. Sardjito. The Data were analyzed by using Chi-squared test, Kolmogorov-Smirnov test, and Mann-Whitney U test with the confidence level of p<0.05 and α=0.05. Results: There was 52 male included in this study. A total of 52 males were infertile, with azoospermia, oligozoospermia, and oligoasthenoteratozoospermia. 2 patients (3.8%) were patients with oligozoospermia, 32 patients (61.5%) were patients with azoospermia and 18 patients (34.6%) were patients with oligoasthenoteratozoospermia. We evaluated 52 ICSI cycle, the percentage of fertilization and pregnancy are 84.6% and 36.5%, respectively. Bivariate analysis showed a significant relationship between wife under 37 years old variable and pregnancy post ICSI procedure with p=0.021 and OR 9.0 (95% CI 1.05-76.4). There was no significant difference between azoospermia, oligozoospermia, and oligoasthenoteratozoospermia and the occurrence of pregnancy post ICSI procedure, p=0.986. Conclusion: The percentage of fertilization and pregnancy post ICSI procedure were 84.6% and 36.5%. Azoospermia, oligozoospermia, and oligoasthenoteratozoospermia variables were not significantly associated with pregnancy post ICSI procedure. ICSI procedure must be carried out immediately before the age of the wife 37 years because of the high success rate
INFLUENCE OF DIABETES MELITUS, BMI, AND HBA1C IN HIGH GRADE PROSTATE CANCER
No full textObjective: This study aims to determine the effect of diabetes mellitus (DM) and body mass index (BMI) on the risk of prostate cancer and high grade prostate cancer. Materials & method: This study is a retrospective observational study with cross-sectional design, using secondary data to determine the relationship of diabetes mellitus, body mass index and HbA1c levels with the degree of differentiation histopathologic prostate cancer. Data were analyzed using Chi-Square test, T-test and Man Whitney test with a confidence level of p<0.05 and a=0.05. Results: There are 78 samples diagnosed with prostate cancer. A total of 12 (15.4%) samples are diabetes mellitus, 18 (22.9%) samples classified as body mass index more than 23.4 (5.1%) samples have elevated levels of HbA1c levels >6.5. On histopathologic examination, it was found as many as 45 (57.7%) samples with high grade prostate cancer, as much as 9 (11.5%) samples with moderate grade prostate cancer, and as many as 24 (30.8%) samples with low grade prostate cancer. In bivariate analysis diabetes mellitus, BMI>23, and HbA1c level relationship with high grade prostate cancer is not statistically significant with p>0.05. Conclusion: There were no statistically significant relationship between diabetes, BMI and increased levels of HbA1c with high grade prostate cancer
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
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
Dispelling 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
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
